    [001] This application is partly a continuation of US Patent Application Serial No. 12 / 461,977, filed on August 26, 2009 and claims its priority benefit. Field of the Invention
    [002] The present description generally refers to the hot-melt adhesive or other thermoplastic material release systems, and more particularly, to a new and improved hot-melt adhesive or other thermoplastic material release system that comprises the use of two pumps separate, independent rotary gear-type metering units with two separate, independent fluid supply passages that provide two different, independent, separate hot melt adhesives or thermoplastic materials to a common substrate from an outlet device or applicator shared or common, or two separate and independent sets of rotary gear metering pumps with two separate and independent fluid supply passages that provide two different, independent, separate hot melt adhesives or thermoplastic materials, which are adapted to emit or discharge precisely measured quantities of the is hot-melt adhesives or other separate and independent thermoplastic materials on a common substrate from shared or common outlet devices or applicators connected respectively to a pump from each set of gear pumps. In addition, the precisely measured quantities of hot melt adhesives or other thermoplastic materials discharged from the two separate and independent rotary gear metering pumps, to which two hot melt adhesives or other separate, different and independent thermoplastic materials were supplied, or from. two separate and independent sets of rotary gear pumps to which two separate and independent thermo-fusible adhesives or other separate thermoplastic materials have been supplied, are in fact capable of being discharged or emitted independently via devices. - exit positives or suitable applicators on a common substrate in such a way as to result in two different adhesives or other thermoplastic materials according to the desired or predetermined standards, or in desired or predetermined locations.
    [003] Furthermore, the precisely measured quantities of two separate, different and independent thermofusible adhesives or other thermoplastic materials that were released from two separate and independent rotary gear pumps, or from two separate and independent assemblies of gear-type rotary pumps, they can also have their outputs combined effectively such that the volumes discharged and emitted from hot-melt adhesives or other thermoplastic materials from the shared or common outlet device or applicator form effectively, for example , a two-part adhesive or other building material or composition for deposition on the common substrate. Examples of the latter are a two-part epoxy which may comprise, for example, an adhesive and a catalyst, or a polymer and foaming agent that can be used to form a suitable gasket used within refrigeration equipment or systems. Fundamentals of the Invention
    [004] In some conventional liquid measurement systems, such as, for example, those that emit, discharge or release hot-melt adhesives or other thermoplastic materials, it is usual to practice to emit or discharge a hot-melt adhesive or other predetermined thermoplastic material through the pumping of such materials through a pump manifold, by means of, for example, a plurality of suitable metering pumps, to one or more outputs with which the appropriate output devices or applicators are connected or fluidly, so as to deposit the particular material on a suitable substrate according to any of the various predetermined standards. Such conventional metering systems typically comprise a motor to drive the pumps at variable speed rates in order to achieve the desired output volumes from the pumps, in order to achieve, in fact, the desired depositions of the materials on the substrates. Consequently, the speed of the drive motor and the drive resulting from the metering pumps, can be changed depending, for example, on the speed of the substrate when it passes through the output devices or applicators. Depending on the structure or configuration of the particular substrate or product on which the hot melt adhesive or other thermoplastic material is being deposited, it is desirable that the system be able to apply, emit or deposit more than one type of adhesive or thermoplastic material simultaneously on a single substrate, that is, the system must be readily capable of processing multiple types of adhesives or other thermoplastic materials. While some systems can achieve the release of multiple adhesives or other thermoplastic materials by providing these adhesives or other thermoplastic materials to multiple applicators, or where hot melt adhesives or other thermoplastic materials are being supplied by separate metering pumps on a common applicator manifold , pressurization and the spatial limitations of such systems have effectively prevented such systems from reaching commercially such volumes emitted, discharged or released from hot-melt adhesives or other thermoplastic materials when feasibly required or desired. For example, in order to supply multiple types of hot melt adhesive or other thermoplastic materials to the adhesive collector, multiple supply hoses must be effectively connected to the adhesive collector for each hot melt adhesive applicator or other thermoplastic material. separate, independent or different being, in fact, supplied with the hot melt adhesive or other particular thermoplastic material to be released, from the adhesive collector. Such a system becomes excessively large, heavy and complex.
    [005] In the state of the art the invention, EP1880772 describes a spreading head particularly for spreading one or more adhesives or mixtures of adhesives, of the hot-melt or cold type, comprising a body having two or more ducts, which are all separate or from which two or more converge, each duct being connected to one or more feeding channels to transport one or more adhesives or adhesive mixes to one or more extrusion chambers formed on the upper body surface ; an abutment element for one or more adhesives or mixtures of adhesives coming out of one or more mixing chambers is associated in an upper region with the body.
    [006] EP1880773 describes a spreading head comprising a body for carrying one or more adhesives to an extrusion tool; the body having two or more ducts, which are all separate or from which two or more converge, and the tool has one or more first extrusion channels and / or one or more mixing chambers that are connected to a or more second extrusion channels, where the first and / or second extrusion channels are optionally mutually overlapping and / or laterally adjacent.
    [007] As yet an illustrative example of the state of the art, the document WO2008089949 describes a device and a method for dosing compounds and, especially, foamed compounds to a target dosing site. The device comprises at least one unit having respective pumps and nozzles that are fluidly interconnected. The pump is a rotary pump comprising at least one rotating element arranged to rotate within a pump chamber.
    [008] So there is a need in the art for a new and improved measuring system for hot melt adhesive or other thermoplastic material that is readily capable of measuring, for example, two hot melt adhesives or other separate, independent and different thermoplastic materials from from a single collector of hot-melt adhesive or other thermoplastic material to a common exit device or applicator so that the required application or deposition, for example, of the two hot-melt adhesives or other separate, independent and different thermoplastic materials in one substrate or product can be achieved at predetermined periods or locations, and according to predetermined and required standards, during a product processing operation. Summary of the Invention
    [009] The previous and other objectives are achieved according to the teachings and principles of the present invention through the provision of a new and improved release system for hot-melt adhesive or other thermoplastic material that includes the use of two separate and independent rotary gear metering pumps with two separate and independent fluid supply passages providing two separate, independent and different hot melt adhesives or other thermoplastic materials on a common substrate from an outlet or applicator device common or shared, or two sets of separate, independent rotary gear metering pumps with two separate and independent fluid supply passages providing two separate hot melt adhesives or other thermoplastic materials, which are adapted to emit or unload precisely measured quantities of two hot-melt adhesives or other separate and independent thermoplastic materials on a substrate from shared or common outlet devices or applicators connected respectively to a pump from each set of gear pumps. In addition, the precisely measured quantities of hot melt adhesives or other thermoplastic materials discharged from two separate and independent rotary gear metering pumps, which were supplied with two hot melt adhesives or other separate, independent and different thermoplastic materials, or from the two separate and independent sets of rotary gear pumps to which two separate hot-melt adhesives or other separate, independent and different thermoplastic materials have been supplied, are capable of being, in fact, independently discharged or emitted via outlet devices or suitable applicators on a common substrate in order to result in two adhesives or other different thermoplastic materials according to the predetermined required or desired standards, or in predetermined required or desired locations. In addition, the precisely measured quantities of the two hot-melt adhesives or other separate, independent and different thermoplastic materials that were released from the two separate and independent rotary gear pumps, or from the two separate and independent sets of pressure pumps. rotating gears can also have their outputs combined effectively such that volumes emitted or discharged from hot-melt adhesives or other thermoplastic materials from the shared or common outlet device or applicator effectively form, for example, a two-part adhesive. parts or other construction material or composition for deposition on the common substrate. Examples of the latter are a two-part epoxy which may comprise, for example, an adhesive and a catalyst, or a polymer and foaming agent that can be used to form a suitable gasket used within equipment or systems of refrigeration.

    [016] FIGs. 5A to 5D illustrate the various patterns of fluid application material produced using the methods of the present invention and the present measurement system, incorporating the principles of the present invention. Detailed Description of the Invention
    [017] With regard now to the drawings, and more particularly to FIGs. 1 to 3, a modality of a new and improved measurement system is illustrated which was built in accordance with the principles and teachings of the present invention and which is generally indicated by the reference character 100. More particularly, the new and improved system - measurement theme 100 will be used to release, for example, two separate, independent and different thermofusible adhesives or other thermoplastic materials from two separate and independent rotary gear metering pumps with two separate and independent fluid supply passages supplying the two hot-melt adhesives or other separate, independent and different thermoplastic materials on a common substrate from a shared or common output device or applicator, or from at least two rotary gear-type metering pumps separate and independent with two separate and independent fluid supply passages the two hot-melt adhesives or other separate, independent and different thermoplastic materials, on a common substrate from the respective shared or common outlet devices or applicators. The depositions of hot-melt adhesives or other thermoplastic materials can be achieved simultaneously when considered in relation to the different pumps of the various gear-type metering pumps of each set of rotary pumps of the gear type, as well as the alternative modes considered in relation to the different pumps of the various gear-type metering pumps of each set of rotary pumps of the gear type depending on the particular configuration of the particular set of rotary pumps of the gear type, as will be more fully described in the present, on a substrate or underlying product as the substrate or product passes under the exit devices or applicators along a product processing line during an operation or application cycle or release of a hot-melt adhesive or other thermoplastic material as can be readily appreciated from FIG. two.
    [018] In summary, as can best be appreciated from FIG. 1, the new and improved measuring system 100 of the present invention is seen as comprising a filtration block 102 for filtering, for example, the two sources of hot melt adhesives or other thermoplastic materials, a first set of gear pumps 104 which comprises, for example, four rotary pumps of the gear type to emit precisely measured quantities of a first hot melt adhesive or other thermoplastic material, a second set of gear pumps 106 for delivering precisely measured quantities of a second hot melt adhesive or thermoplastic material , which may be different from the first hot-melt adhesive or thermoplastic material, an adhesive collector 108 for driving the first and second hot-melt adhesive or other thermoplastic materials, emitted by means of the first and second set of gear pumps104, 106 to a set of suitable output devices or applicators 110, and a set of o of drive motors 112 operatively connected to the adhesive collector 108 to drive the gear members, not shown, of the first and second sets of gear type pumps 104, 106, as will also be described more specific to follow. The input sources for the two hot-melt adhesives or other thermoplastic materials are adapted to be fluidly connected to the adhesive collector 108 and are consequently illustrated schematically in S1 and S2 in FIG. 1. In addition, it is also appreciated that, as will be more fully described, while each of the first and second gear pump sets 104, 106 is illustrated comprising four gear-type rotary metering pumps, the particular number of such rotary gear type pumps, each of the first and second gear pump sets 104, 106, may vary as required or desired.
    [019] More particularly, and with respect to FIG. 1, it is appreciated that the output drive shaft, not shown, of the drive motor assembly 112 is adapted to be operatively connected to the drive shaft 114 of the first set of gear pumps 104 to which the transmission gear main 116 is fixedly mounted. Thus, as the output shaft, not shown, of the drive motor assembly 112 is rotated, for example, clockwise (CW), the drive shaft 114 and the main drive gear 116 of the first set of gear pumps 104, will also be rotated clockwise (CW) as indicated by arrow A. The outer periphery of main drive gear 116 of the first set of gear pumps 104 is provided with a predetermined number of gear teeth 118, and it is observed that the adhesive collector 108 is supplied with an intermediate gear 120 which is fixedly mounted to the rotating shaft 121, while the second set of gear pumps 106 is supplied with a driven gear 122, where the outer peripheries of the intermediate gear 120 and the driven gear 121 are also provided with a predetermined number of gear teeth 124, 126.
    [020] Consequently, as can be clearer from FIGs. 2 and 3, when the first set of gear pumps 104 is fixedly mounted, but removable, on top of the upper surface part 128 of the adhesive collector 108, and when the second set of gear pumps 106 is mounted so fixed, but removable, on the left side wall 130 of adhesive collector 108, the transmission and drive gears 116,122 of the first and second set of gear pumps104, 106 will be interlocked to the intermediate gear 120 dovo 108 so that the clockwise rotation (CW) of the transmission gear 116 of the first set of gear pumps 104 will effectively result in the anti-clockwise rotation (CCW) of the intermediate gear 120 in the adhesive collector 108 and, in turn, time, the clockwise rotation (CW) of the driven gear 122 of the second set of gear pumps 106, as denoted respectively by arrows B, C, the first and the second co set of gear pumps104, 106 can pump hot melt adhesives or other thermoplastic materials.
    [021] It is further appreciated that as a result of the removable and independent assembly of the first and second set of gear pumps104, 106 in the adhesive manifold 108, each of the gear pump sets 104, 106 can be removed - independently of the adhesive collector 108 in relation to the other gear pump sets104, 106 for the purpose of repairing, maintaining or replacing a particular set of gear pump sets104, 106 with a set of different gear pumps having, for example, a different volumetric outlet rate. Still further, it is also appreciated that as a result of the main transmission gear of the first set of gear pumps 104 having a predetermined number of external gear teeth 118, and similarly, as a result of the intermediate gear 120 of the adhesive collector 108 and the driven gear 122 of the second set of gear pumps 106 also having a predetermined number of external gear teeth 124, 126, a predetermined gear ratio is effectively established between the teeth of gear 118 of the transmission gear 116 and the gear teeth 124, 126 of the intermediate and driven gears 120, 122 so that the gear pump sets104, 106 have predetermined volumetric output rates. However, it is further appreciated that the particular volumetric output rate of a particular set of gear pump sets 104, 106 can be changed or altered by providing one or both of the sets of gear pumps 104, 106 with a transmission gear or driven 116, 122 different having a different number of gear teeth 118, 126, which then, in fact, would change or alter the gear ratio effectively defined between that particular drive gear 116 and the driven gear 122, of the first and second set of gear pumps 104, 106, as well as with respect to the intermediate gear 120 of the adhesive collector 108. Depending on whether a larger or smaller transmission gear 116 is mounted to the first set of gear pumps 104, or if a larger or smaller driven gear 122 is fitted to the second set of gear pumps 106, the linear and angular arrangement of the intermediate gear 12 0 in the adhesive collector 108 can be changed by means of an attached arm or support 123.
    [022] Lastly, with regard to the structural arrangement of the various components of the measurement system 110 described in FIG. 1, that the filter block 102 is adapted to be fixedly mounted to the end of the adhesive collector 108 opposite the end on which the intermediate gear 120 is located. In order to accommodate or facilitate the assembly of the filtration block 102 to such an opposite end of the adhesive collector 108, the adhesive collector 108 is provided with an integrated mounting block 132, and it is observed that a pair of openings 134, 136 it is formed within an upper flanged portion 138 of the mounting block 132 to accept or accommodate suitable mounting screws, not shown.
    [023] In a similar manner, the side wall face or part 140 of the filter block 102 is also provided with a pair of openings 142, 144 for accepting or accommodating the mounting screws, not shown. In addition, the side wall part or face 140 of the filter block 102 is also provided with a pair of outlet passages 146a, 146b to provide, for example, the two hot-melt adhesives or other different thermoplastic materials, towards and towards the adhesive collector108, and a pair of inlet passages 148a, 148b to allow the hot melt adhesive or other recirculated thermoplastic material to be driven back from adhesive collector 108 and to the filtration block 102, the hot-melt adhesive or other recirculated thermoplastic material can once again be carried out of the filter block 102 and towards the adhesive collector 108 via the supply outlet passages 146a, 146b. It is recalled that the original sources, for example, of the two hot-melt adhesives or other different thermoplastic materials are originally fluidly conveyed to the adhesive collector through suitable ducts schematically illustrated in S1 and S2.
    [024] As noted above, each of the gear pump set pairs 104, 106 comprises a predetermined number of gear pumps 150, 152 respectively. In the illustrated embodiment, the number of gear pumps 150, 152 comprising each of the gear pump sets 104, 106 is equal to four, however, that number may be more or less than four as may be desired or required in conjunction with a particular product or substrate processing line.
    [025] Consequently, now with respect to FIG. 3, the fluid flow paths for a particular pump of the gear pumps 150, 152 of the first and second set of gear pumps104, 106, through the adhesive collector 108 and through the outlet device or applicator 110, of in order to be emitted, discharged or released on the substrate or product 154 being conducted under the outlet device or applicator 110 along a product processing line 156, schematically illustrated in FIG. 2, will be described now. More particularly, with reference to FIG. 3, the adhesive collector 108 is illustrated as having the first set of gear pumps 104, comprising a particular pump of its gear pumps 150, is fixedly mounted, but removable to the upper surface part 128 thereof, while the second set of gear pumps 106, comprising a particular pump of its gear pumps 152, is fixedly mounted, but removable to the left side wall part 130 thereof. The adhesive collector 108 is provided with a pair of axially extending fluid supply passages 158a, 158b, which are respectively adapted to be fluidly connected to the hot melt adhesive or other thermoplastic material supply outlet passages 146a, 146b defined within the filtration block 102, as illustrated in FIG. 1, and is also provided with a pair of axially extending recirculating or fluid return passages 160a, 160b, which are adapted to be fluidly connected to the inlet passages of hot melt adhesive or other thermoplastic material 148a, 148b defined within the filtration block 102, as illustrated in FIG. 1.
    [026] It is also appreciated from FIG. 1 that the transmission gear 116 and the driven gear 122, respectively associated with the gear pump sets 104, 106 and respectively driven by means of the drive motor set 112, and the coupling coupled with the intermediate gear 120 arranged on the rotary axis 121 of the adhesive collector 108, the rotary axes 114, 164 which are illustrated in FIGS. 1 and 3. The shafts 114, 116, in turn, have the transmission gears 166, 168 fixedly mounted to them and internally arranged inside the gear pump sets 104, 106, and the transmission gears 166 , 168 are, in turn, coupled with the driven gears of the gear pump 170, 172 of the gear train sets arranged respectively internally within each of the gear pumps 150, 152. Consequently, the supply of hot melt adhesive or other thermoplastic material is supplied from the supply outlet passages 146a, 146b of the filtration block 102, to the supply passages 158a, 158b of the adhesive collector 108, and with respect to the use or operation of a gear pump particular 150, when it is used to pump a first one, for example, of the two different hot melt adhesives or other thermoplastic materials from the supply source S1, this first of the different adhesives hot-melts or other thermoplastic materials will be conducted, for example, into the annular space surrounding the outer periphery of the adhesive collector transmission gear 166 through a connected fluid supply passage 174a extending upwardly within the collector. adhesive 108 and to the base or bottom part of the gear pump assembly 104. A similar connected fluid supply passage 174b is provided, of course, provided internally within the adhesive manifold 108, in conjunction with the particular gear pump 152, and such passage 174b extends left to the right end portion of the gear pump set 106, as seen in FIG. 3, in order to introduce, for example, a second hot-melt adhesive or other thermoplastic material into the annular space surrounding the outer periphery of the transmission gear of the adhesive collector 168.
    [027] Returning to the gear pump 150, the fluid output from the gear train, internally disposed within the gear pump 150 and including gear driven by gear pump 170, is conducted out of the gear pump gears 150 by means of a first vertically oriented supply outlet passage 176, which extends downwardly through the gear pump assembly 104, and a second vertically oriented supply outlet passage 178 which is fluidly connected to the end a downstream of the first vertically oriented supply outlet passage 176 and which is defined within the adhesive collector 108. The downstream end of the second vertically oriented supply outlet passage 178 is in turn connected fluidly to the upstream end of a third horizontally oriented delivery outlet passage 180 which is defined within the adhesive collector 108, and the downstream end te of the third horizontally oriented supply outlet passage 180 is in turn connected fluidly to an end upstream of a fourth horizontally oriented supply outlet passage 182, which is defined within the outlet device or applicator 110. A fifth vertically oriented supply outlet passage 184 has a central portion of this fluidly connected to the downstream end portion of the fourth horizontally oriented supply outlet passage 182, and the downstream end part of the fifth supply outlet passage vertically oriented 184 is fluidly connected to a central part of a sixth horizontally oriented delivery outlet passage 186 which is also defined within the outlet device or applicator 110. It is further noted that the downstream end portion of the sixth passage horizontally oriented delivery outlet 186 is fluidly connected to a release 188, disposed at the bottom of the outlet device or applicator 110, through the intermediary of a set of electronically controlled solenoid activated control valves 190, the detailed structure of which will be provided in a summary form below.
    [028] The valve-controlled output of the set of electrically controlled and solenoid-activated control valves 190 is actually fluidly connected via a seventh vertically oriented supply outlet passage 187 and an eighth horizontally oriented supply outlet passage 189 that actually leads to the outlet port of the release nozzle member 188. Finally, it is observed that the central part of the fifth vertically oriented supply outlet passage 184 is also fluidly connected to a set of pressure relief valves 191, which it is arranged inside a hole 210 of the outlet device or applicator 110, by means of a ninth horizontally oriented fluid passage 193, in order to effectively define a return flow path for the hot melt adhesive or other thermoplastic material in a direction that is opposite to the supply flow of the hot melt adhesive or other thermoplastic material and that takes d direction to the set of electrically controlled solenoid activated control valves 190 and the release nozzle member 188, as will be described more particularly below. The hot melt adhesive or other thermoplastic material is effectively expelled or returned to the first supply source S1 of hot melt adhesive or other thermoplastic material, through the pressure relief valve set 191, when the control valve set is activated electrically controlled solenoid 190 is moved to its closed position so that no further release of hot melt adhesive or other thermoplastic material from the release nozzle member is permitted.
    [029] In a similar manner, it is also appreciated that the fluid output of the gear train, arranged internally within the gear pump 152 and including gear driven by gear pump 172, is conducted externally from the gear pump 152 by means of a first horizontally oriented supply outlet passage 192, which extends horizontally through the gear pump assembly 106, and a second horizontally oriented supply outlet passage 194 which is fluidly connected to the downstream end of the first horizontally oriented supply outlet passage 192 and which is defined within the adhesive collector 108. The part of the downstream end of the second horizontally oriented supply outlet passage 194 is, in turn, fluidly connected to the upstream end of a third vertically oriented supply outlet passage 196 which is also defined d into the adhesive collector 108, and the downstream end portion of the third vertically oriented supply outlet passage 196 is in turn connected fluidly to the upstream end of a fourth horizontally oriented supply outlet passage 198 defined within the adhesive collector 108. A fifth horizontally oriented delivery outlet passage 200, defined within the upper left center of the outlet device or applicator 110, has its upstream end part fluidly connected to the downstream end part of the fourth horizontally oriented supply outlet passage 198, while the downstream end part of the fifth horizontally oriented supply outlet passage 200 is fluidly connected to a substantially central part of the vertically oriented fifth supply outlet passage 184 of a similar to the fluid connection of the fourth supply outlet passage horizontally oriented 182 operatively associated with a gear pump 150.
    [030] As noted, the downstream end part of the fifth vertically oriented supply outlet passage 184 is fluidly connected to a central part of a sixth horizontally oriented supply outlet passage 186 which is defined within the exit device or applicator 110 and which finally leads to the release nozzle 188, however, it is also observed that the opposite end of the fifth vertically oriented supply exit passage 184 is connected fluidly, and ends effectively, in a plug pressure relief 202 disposed inside a hole 208. The reason for this is that when the first hot melt adhesive or other thermoplastic material, supplied from the first supply source S1, is being pumped by means of one of the pumps 150 of the first set of gear pumps 104 so that it is discharged or released out of the associated release nozzle 188, its associated pump from pumps 152 of the second set of gear pumps 106, which would normally be receiving a supply of the second hot melt adhesive or other thermoplastic material from the second supply source S2, is not being used, is not, in fact, receiving a supply from the second hot melt adhesive or other thermoplastic material from the second supply source S2, and is intended to be removed from the second set of gear pumps 106. Consequently, as none of the second hot melt adhesive or other thermoplastic material is being pumped from that particular pump of the four pumps 152 comprising the second set of gear pumps 106, plug 202 is used to effectively close that top end portion of the fifth vertically oriented supply outlet passage 184 which is adapted to be fluidly connected back to the source supply S2. On the other hand, as the first hot-melt adhesive or other thermo-plastic material is being pumped through the particular pump of the pumps 150 of the first set of gear pumps 104, when the set of electrically controlled solenoid-activated control valves 190 it is moved to its closed position so that no more release of hot-melt adhesive or other thermoplastic material, pumped by means of the private gear pump 150 of the first set of gear pumps 104 to the release nozzle 188 is allowed, where the first hot-melt adhesive or other thermoplastic material is capable of being effectively returned or expelled to the first supply source of hot-melt adhesive or other thermoplastic material S1 through the set of pressure relief valves 191.
    [031] It is further understood that the reverse situation is similarly true, that is, when one of the particular gear pumps 152 is pumping the second hot-melt adhesive or other thermoplastic material towards the release nozzle member 188, and its associated gear 150 of the first set of gear pumps 104 is not being used and has been removed from said first set of gear pumps 104, the pressure relief valve set 191 is now located in the position in which plug 202 is illustrated, that is, inside hole 208, and plug 202 is located in the position in which the pressure relief valve assembly 191 is illustrated, that is, inside hole 210. Thus, when the control valve assembly activated by electrically controlled solenoid 190 is moved to its closed position so that no more release of hot-melt adhesive or other thermoplastic material pumped through the particular gear pump home 152 of the second set of gear pumps 106 to the release nozzle member 188 is allowed, where the second hot melt adhesive or other thermoplastic material is capable of being effectively returned or expelled to the second supply source S2 of second adhesive hot-melt or other thermoplastic material through the pressure relief valve set 191.
    [032] With respect also to FIG. 3, it is also noted that, depending on the particular pattern or the location in which one wishes to deposit one of the two hot-melt adhesives or other separate, independent and different thermoplastic materials on the underlying substrate or product, they have just been described effectively different pumps, for example, of the four private pumps 150, 152 of the first and second set of gear pumps104, 106, which will be used in a particular period during the process, operation or deposition cycle of hot melt adhesive or other thermoplastic material. In conjunction with the use of private pumps 150, 152 of the first and second set of gear pumps104, 106, it is clear that pairs of pumps 150, 152 of the first and second set of gear pumps104, 106 will effectively share the same output device or applicator 188. In conjunction with the particular pumps, for example, the four pumps 150, 152 of the first and second set of gear pumps104, 106, which will or will not be used, a pair of plugs, such as, for example shown in 204, 206 can be effectively installed within, for example, supply outlet passages 182, 200, in order to effectively block or restrict the flow of fluid from that supply outlet pass 182, 200. As well as if, in conjunction with plugs 204, 206, the particular pump of pumps 150, 152 is not being used to pump, or the first or second hot-melt adhesive or other thermoplastic material will preferably be r moved from its first or second set of gear pumps 104, 106.
    [033] Consequently, depending on the particular location of plugs 204, 206 within the supply outlet passages mentioned above, two pumps other than the first and second set of gear pumps 150, 152 can discharge their hot-melt adhesives or other thermoplastic materials emitted from an alternative mode through the same release nozzle 188, or through separate and independent release nozzles188 as will be described in more detail in conjunction with FIG. 4. In addition, the two pumps other than the first and second set of gear pumps 150, 152 can simultaneously discharge their hot-melt adhesives or other thermoplastic materials through the same release nozzle 188 if, for example, it is desired to combine the two hot-melt adhesives or other thermoplastic materials, such as, for example, when a two-part adhesive or other thermoplastic material is deposited on the substrate or product. Examples of such adhesives include a two-part epoxy comprising, for example, an adhesive and a catalyst, or a polymer and foaming agent that can be used to form a suitable gasket used in refrigeration equipment or systems. It is also noted that the additional permanent plugs 203, 205 are respectively arranged in the third vertically oriented supply outlet passage 196 and in the six horizontally oriented supply outlet passage 186, defined respectively within the adhesive collector 108 and the device outlet or applicator 110 in order to permanently block the end parts upstream of such supply outlet passages such that there is no leakage of the hot melt adhesive or other thermoplastic material.
    [034] Finally, as described above, a description of the electrically controlled solenoid-activated control valve set 190 will not be presented briefly. The outlet device or applicator 110 is provided with a hole 212 inside the which, a valve mechanism, comprising a ball valve member 216, is adapted to be arranged. The ball valve member 216 is adapted to engage a bottom part of a valve base member 220 when the ball valve member 216 is arranged in its closed and raised position, and it is further observed that the ball valve member 216 is fixedly mounted on the lower end part of a vertically oriented valve stem 224. The upper end part of valve stem 224 is fixedly mounted inside a piston member 228, and the piston member 228 is normally tilted or assisted towards its highest or upper position by means of a spiral spring 232. The electrically controlled solenoid actuated control valve set 190 further comprises a solenoid activator 236 and a pressure port. control air inlet 240. Control air inlet port 240 is fluidly connected to a pair of control air outlet ports 244, 246 via a fluid passageway disposed internally within the solenoid activator 236, but not shown for clarification. Control air outlet ports 244, 246 fluidly connect solenoid actuator 236 to piston housing 252 of valve assembly 190 and solenoid activator 236 is understood or appreciated to comprise suitable valve mechanisms internally arranged therein, but not shown for the purpose of clarity, which will respectively control the flow of inlet control air from control air inlet port 240 to one of control air outlet ports 244, 246. In this way, the control air can, in fact, act on the upper surface or the lower surface part of piston member 228 and thereby control the vertical arrangement of piston member 228 which, in turn, will control the arrangement of the ball valve member 216 with respect to its valve base 220. Consequently, the ball valve member 216 will alternatively be arranged and will define the closed or open states that will prevent them from being between the flow of the hot melt adhesive or other thermoplastic material towards the release nozzle member 188, or it will allow the flow of the hot melt adhesive or other thermoplastic material towards the release nozzle member 188. Finally, the pair of mufflers 256, 258 is operatively associated with the control air inlet 240 in order to effectively silence the sound of the control air expelled when the piston member 228 is moved between its upper and lower positions in order to move the member respectively. ball valve 216 between its closed and open positions.
    [035] Having described substantially all the structural components of the new and improved measuring system 100 of the present invention, a brief description of a particular mode of operation of the new and improved measuring system 100 of the present invention will now be presented with reference mainly to FIG. 4, but also in conjunction with FIG. 2. With reference then to FIG. 4, it is observed that, for example, the two hot-melt adhesives or other separate, independent and differentiated thermoplastic materials provided in the new and improved measurement system 100 from the supply sources S1, S2 and that the hot-melt adhesives or other thermoplastic materials pass respectively through a pair of filter members 300, 302 arranged respectively within the filter block 102. From the filter members 300, 302, it is observed that the two hot-melt adhesives or other separated thermoplastic materials, independent and different from the supply sources S1, S2 are supplied, for example, to gear pumps 150a, 150b, 150c, 150d of the first set of gear pumps 104, as well as, for example, gear pumps 152a, 152b, 152c, 152d of the second set of gear pumps 106.
    [036] It is further noted that the output sources of hot-melt adhesives or other thermoplastic materials from gear pumps 150a, 150b, 150c, 150d are driven respectively towards the release nozzles 188a, 188b, 188c, 188d along of the respective supply outlet passages described in conjunction with FIG. 3 and through electrically controlled solenoid activated control valves 190a, 190b, 190c, 190d. Similarly, the output sources of hot-melt adhesives or other thermoplastic materials from gear pumps 152a, 152b, 152c, 152d are also conducted towards the release nozzle members 188a, 188b, 188c, 188d along the various supply outlet passages described in conjunction with FIG. 3 and through the electrically controlled solenoid activated control valves 190a, 190b, 190c, 190d. Remember that hot melt adhesive or other particular thermoplastic material that flows from separate, independent and different sources S1, S2 will only be pumped by means of the private pumps 150a, 152a, 150b, 152b, 150c, 152c, 150d, 152d and driven to the particular output device or applicator 188a, 188b, 188c, 188d, depending on whether or not one of the configuration plugs 204, 206 was installed inside a respective passage of the supply passages 182, 200 associated in an operational and fluid way with a particular pump of the pumps 150a, 152a, 150b, 152b, 150c, 152c, 150d, 152d.
    [037] It can then be appreciated that when, for example, the electrically controlled solenoid activated control valve 190a is moved to its closed position, the outlet source of the hot melt adhesive or other thermoplastic material from one of the good - gear bases 150a / 152a that pumped its hot-melt adhesive or other thermoplastic material, as allowed by means of the aforementioned configuration plugs 204, 206, will be blocked and disconnected in flow path 184a in order to be led out through the valve pressure relief valve 191a and through one of the return or recirculation paths 160a / 160b, as described in FIG.3, to return to one of the filter members 300 or 302 of the filter block 102. Similarly, when, for example, For example, the electrically controlled solenoid-operated control valve 190b is moved to the closed position, the output source of the hot melt adhesive or other thermoplastic material from one of the gear pumps 1 50b / 152b, depending again on the particular location of the configuration plugs, will be effectively blocked and disconnected on flow path 184b in order to be led out through the pressure relief valve 191b and through one of the pressure paths. return or recirculation 160a, 160b, as described in FIG.3, to return to one of the filtration members 300 or 302 of the filtration block 102. Similar operations and fluid flows of hot-melt adhesives or other thermoplastic materials can, of course , be accompanied in conjunction with gear pumps 150c, 152c, and pumps 150d, 152d, electrically controlled solenoid activated control valves 190c, 190d and pressure relief valves 191c, 191d. It is appreciated that as all gear pumps 150 within the first set of gear pumps 104 are supplied with hot melt adhesive or other thermoplastic material from the first supply source S1, all hot melt adhesive or other material thermoplastic being recirculated or returned to the first supply source S1 from all gear pumps 150 comprising the first set of gear pumps 150 is, in fact, recirculated or returned via the return or recirculating flow path 160a. Similarly, with respect to all gear pumps 152 comprising the second set of gear pumps 106, that is, all hotmelt adhesive or other thermoplastic material being recirculated or returned to the second supply source S2 from all pumps of gears 152 comprising the second set of gear pumps 152 is actually recirculated or returned via the recirculating or return flow path 160b.
    [038] It is also appreciated that through the new and improved measurement system 100, as constructed in accordance with the principles and teachings of the present invention, the emission or release of hot-melt adhesives or other thermoplastic materials, from the nozzle members release 188a, 188b, 188c, 188d, for the discharge, release or deposition of hot-melt adhesives or other thermoplastic materials on the substrate or product 154, as illustrated in FIG. 2 and 3, can effectively reach three operational states. The first operational state is the state where, for example, as already described, the first of the electrically controlled solenoid activated control valves 190a was moved to its open position, with the outlet of the hot-melt adhesive or other thermoplastic material a from the release nozzle member 188a is the hot melt adhesive or other thermoplastic material supplied via the supply source S1. The hot melt adhesive or other thermoplastic material is allowed to flow from the supply source S1 to the release nozzle member 188a as a result of installing the plug member 206 within the fifth horizontally oriented supply outlet passage 200 defined within. from the upper left center of the delivery device or applicator 110, all illustrated in FIG. 3, and removing the plug 204 from the fourth horizontally oriented supply outlet passage 182 which is defined within the outlet device or applicator 110 as is also described in FIG. 3. In addition, pressure relief valve 191a was located inside hole 210 of the outlet device or applicator 110, and pressure relief plug 202 was located inside hole 208 of the outlet device or applicator. 110.
    [039] The second operational state is the state where, for example, as already described, the first of the electrically controlled solenoid activated control valves 190a has been moved to its open position, however, plug member 204 has been installed now within the fourth horizontally oriented delivery outlet passage 182, and plug 206 has been removed from the fifth horizontally oriented delivery outlet passage 200 defined within the upper left center of the delivery device or applicator 110, all as illustrated in FIG. 3. Consequently, the exit of the second hot-melt adhesive or other thermoplastic material from the pump 152a and the release nozzle member 188a is now allowed and facilitated. In addition, pressure relief valve 191a has now been placed into hole 208 of the outlet device or applicator 110, and pressure relief plug 202 has now been located into hole 210 of the outlet device or applicator 110 in order to allow the return flow and recirculation of the hot melt adhesive or other thermoplastic material back to the filtration block 302 when the electrically controlled solenoid activated control valve 190a was moved to its closed position.
    [040] The third operational state is the state where, for example, as already described, the first of the electrically controlled solenoid activated control valves 190a has been moved to its open position, however, both plug members 204, 206 have been removed from their respective supply outlet passages, both of which hot-melt adhesives or other thermoplastic materials from supply sources S1, S2 are now capable of being conducted and released externally from the release nozzle member188a. As noted, such circumstances can be achieved when it is desired, for example, to release a two-part adhesive or other building material or composition for deposition on the common substrate. Examples of the latter are a two-part epoxy that may comprise, for example, the adhesive and a catalyst, or the polymer and foaming agent that can be used to form a suitable gasket used within refrigeration systems or equipment. , of course, that similar operations can be achieved in conjunction with gear pumps150a, 152a, 150b, 152b, 150c, 152c, 150d, 152d as well as together with their associated release nozzle members 188b, 188c, 188d, the electrically controlled solenoid activated control valves 190b, 190c, 190d and the pressure relief valves 191b, 191c, 191d and the like. It is also appreciated that, while the description and drawings were directed to supply two sets of gear pumps104, 106, comprising respectively the various gear pumps 150, 152, sets of additional gear pumps, comprising the pumps of additional gears, can certainly be incorporated into the 100 measurement system. Such additional gear pump sets, their associated gear pumps, electrically controlled solenoid activated control valves and relief valves have been added to the system measurement 100 to provide hot melt adhesives or other additional thermoplastic materials when desired or required according to predetermined or required standards, or at predetermined required or desired locations.
    [041] With respect again to FIG. 2, it is appreciated that an additional operational condition, in addition to those described above, can be readily achieved according to the principles and teachings of the present invention through the measurement system 100. More particularly, it is recalled that each of the sets of gear pumps 104, 106 comprises, for example, four gear pumps 150, 152 which are arranged in an arrangement side by side with each other as described in FIGS. 1 and 2. For purposes of clarification, and to illustrate the additional operating condition of the measuring system 100 of the present invention, the four gear pumps in each set of gear pumps 104, 106 have been designated as the gear pumps. gears 150a, 150b, 150c, 150d, 152a, 152b, 152c, 152d. In addition, each of the gear pumps 150a, 150b, 150c, 150d, 152a, 152b, 152c, 152d has operationally associated with them electrically controlled solenoid activated control valves 190 / 150a, 190 / 150b, 190 / 150c , 190 / 150d, 190 / 152a, 190 / 152b, 190 / 152c, and 190 / 152d, some of which have been illustrated in FIG. 4. It is further appreciated that the side-by-side arrangement of gear pumps 150a, 150b, 150c, 150d, 152a, 152b, 152c, 152d will lead to or enable deposits side by side of hot-melt adhesives or other thermoplastic materials from individual, suitable release nozzle members 188 / 150a, 188 / 150b, 188 / 150c, 188 / 150d, 188 / 152a, 188 / 152b, 188 / 152c, 188 / 152d, some of which have also been illustrated in FIG . 4, on the underlying product or substrate 154 so as to effectively define side-by-side planes or longitudinally extending strips 266, 268, 270, 272 of the hot melt adhesives or other thermoplastic materials on the underlying product or substrate 154.
    [042] With respect again to FIG. 2, it is also appreciated that the total width of a specific type of hot-melt adhesive or other thermoplastic material deposited on the underlying product or substrate 154 can vary, that is, it can extend through two plates 268, 270 as in 274, it can be relatively narrow in order to effectively occupy only a single plane as described, for example, in 266 or 272, or the different hot-melt adhesives or other thermoplastic materials can be deposited inside any one or more from planes 268, 270, 272, 274 in order to achieve several different or mixed patterns at several different locations in the product or substrate, all depending on whether or not a particular pump of the gear pumps 150a, 150b, 150c, 150d, 152a , 152b, 152c, 152d is being used, whether or not the outflow of the first or second hot-melt adhesive or other thermoplastic material from the supply sources S1, S2, by means of a particular pump of the gear shafts 150a, 150b, 150c, 150d, 152a, 152b, 152c, 152d were allowed to flow to their respective release nozzle members 188a, 188b, 188c, 188d by activating the respective electrically controlled solenoid activated control valves 190a, 190b, 190c, 190d, and as a result of the predetermined or selected arrangement of plugs 204a, 204b, 204c, 204d, 206a, 206b, 206c, 206d within the fourth horizontally oriented supply outlet passage 182a, 182b, 182c, 182d, or the fifth horizontally oriented supply outlet passage 200a, 200b, 200c, 200d defined within the outlet device or applicator 110, as well as the location of the respective pressure relief valves 191a, 191b, 191c, 191d and the respective pressure relief plugs 202a, 202b, 202c, 202d into the appropriate holes 208a, 208b, 208c, 208d, 210a, 210b, 210c, 210d.
    [043] Thus, it can be seen that according to the principles and teachings of the present invention, a new and improved release system for hot-melt adhesive or other thermoplastic material has been described, comprising the use of two separate rotary gear metering pumps and independent with two separate and independent fluid supply passages providing two different, independent, separate hot melt adhesives or thermoplastic materials on a common substrate from a shared or common outlet device or applicator, or two separate and independent sets of rotary metering pumps of gears with two separate and independent fluid supply passages providing two different, independent and separate hot-melt adhesives or thermoplastic materials that are adapted to emit or discharge precisely measured quantities of two hot-melt adhesives or other thermoplastic materials if stopped and independent on a common contract from common or shared output devices or applicators respectively connected to a pump from each set of gear pumps.
    [044] Furthermore, the precisely measured quantities of hot-melt adhesives or other thermoplastic materials discharged from the two separate and independent rotary gear metering pumps, which were supplied with two hot-melt adhesives or other separate, independent and different thermoplastic materials, or from the two separate and independent sets of rotary gear pumps to which two separate hot-melt adhesives or other separate, independent and different thermoplastic materials have been supplied, they are, in fact, capable of being independently discharged or emitted through suitable outlet devices or applicators on a common substrate to result in two hot-melt adhesives or other different thermoplastic materials according to predetermined or required standards, or at predetermined or required locations. In addition, the precisely measured quantities of the two hot-melt adhesives or other separate, independent and different thermoplastic materials that have been released from the two separate and independent rotary gear pumps, or from the two separate and independent sets of rotary pumps of gears, can also have their outputs effectively combined so that the volumes discharged or emitted from the hot melt adhesives or other thermoplastic materials from the common or shared output device or applicator effectively form, for example, a two-part adhesive or other construction material or composition for deposition on the common substrate. Examples of the latter are a two-part epoxy that can comprise, for example, an adhesive and a catalyst, or a polymer and foaming agent that can be used to form a suitable gasket used within refrigeration equipment or systems.
    [045] The present system is used to execute a method to manufacture an article having a substrate and two materials applied to it. In such a method, a measured fluid delivery system 100 is provided. The system has the first and second source of supply to supply the first and second fluid, respectively, an outlet device having at least one release nozzle, at least two pumps to pump the first and second fluid from their respective supply sources for at least one release nozzle.
    [046] At least two pumps are in close proximity to at least one release nozzle. The supply outlet passages interconnect at least the two pumps to at least one release nozzle, and the flow control elements selectively control the passage of the first and second fluid from each of at least two pumps. at least one release nozzle.
    [047] The release system is configured for at least three release states, a first state in which the first fluid is released from a first of at least two pumps to at least one release nozzle, a second state in which the second fluid is released from a second of at least two pumps to at least one release nozzle, and a third state in which the first and second fluid are released from the first and second steel pumps at least two pumps for at least one release nozzle.
    [048] The method further includes driving the substrate through the fluid release system in a machine direction and applying the first, or the second, or the first and the second fluid to the substrate in a plurality of segments. Each segment has a volume per unit length and is applied to a length in the machine direction to define a pattern. The standard includes at least some areas in which the first or second fluid is present without the other fluid.
    [049] Exemplified patterns are illustrated in FIGs. 5A to 5D. In FIG. 5A, a window pattern 400 is illustrated in which the first fluid can be present in the area indicated in 402 and the second fluid can be present in the area indicated in 404. As will be clear to those skilled in the art, the area indicated in 404 can be formed with both the first and the second fluid, or, as illustrated, only with the first fluid.
    [050] In FIG. 5B, a ladder pattern 500 is illustrated. In this pattern, the first fluid can be present in the area indicated in 502 and the second fluid can be present in the area indicated in 504. It is understood that the area indicated in 506 can be formed with both the first and the second fluid, or, with the first fluid only or with the second fluid only.
    [051] In FIG. 5C, a striped pattern 600 is illustrated. In this pattern, either the first or the second fluid is applied in an elongated manner in the machine direction as shown in 602, and the second fluid is applied in discrete areas, such as in 604. It is understood that in the areas indicated in 604 , the first fluid may or may not be present, as desired.
    [052] In a last exemplified pattern, a freeform pattern 700 is illustrated in FIG. 5D. In this, the first fluid is contiguous and is present in the areas indicated in 702 and the second fluid is present along the edges (in a pattern), as indicated in 704.
    [053] As such, it is appreciated that the fluids (both the first and the second fluid) can be non-contiguous in the machine direction. And, the fluids can be non-contiguous in the transverse direction. In addition, the fluid (again, both the first and the second fluid) can be non-contiguous in both the machine and transverse directions.
    [054] Fluids can be applied in a variety of processes, including in a contact application (for example, coated with grooves) or in a non-contact application (for example, spray coating). The fluids can be applied, at least in some areas, coinciding with each other.
    [055] In addition, if desired, the volume of one or both of the first and the second fluid can be increased per unit length by at least a predetermined length of a segment in the machine direction. And, the volume of one or both of the first and the second fluid can be increased per unit length by at least a predetermined length of a plurality of segments in a transverse direction.
    [056] In a preferred method, the measured fluid delivery system includes at least two release nozzles and at least two pumps associated with each of the first and second fluids. In such a method, the passages are arranged inside a collector, preferably a non-flexible collector that does not allow expansion.
    [057] The method may also include the step of applying a member, such as a flexible member (for example, a non-woven member or other textile-like member, a resilient member, or the like), on the substrate and the first or the second fluid or the first and the second fluid. An article can be formed using the present method.
    [058] Obviously, many variations and modifications of the present invention are possible in view of the above teachings. It is understood, therefore, that within the scope of the appended claims, the present invention can be practiced contrary to what has been specifically described in this document.
