    The invention relates to a device for producing hair zones for brushes, in particular toothbrushes, comprising a stock of bristles and a device for taking out individual hair tufts. in the stock of hair and a transport device for transporting the tufts of bristles in holes of a receiving plate by means of a flow of gas or air.
    Such a device is known for example from document EP 0 405 204 B1. Several tufts of filaments are transported through flexible hoses in a support plate. The tufts of filaments are then melted with a thermoplastic support plate and / or coated with plastic to form a brush head. The filling rate of the holes of the mold receiving the tufts of filaments, subordinate to the supply of tufts of hair by means of a flow of gas or air, is relatively low since the supply ducts for transport tufts by means of a flow of gas or air allow only a limited filling rate, without the supply ducts clog or that individual filaments remain in the supply duct during transport. The fill ratio is the ratio of the cross section of the hole of a plate to the sum of all cross sections of filaments retained in this hole. The low filling rate has the consequence that during the coating of the pile filaments under high injection pressure, the injection material passes through the filaments and is visible on the surface of the brush, which is not not nice to see or can make the brush unusable.
    The problem, therefore, is to provide a device of the type mentioned at the beginning with which improved tufts transport and denser stuffing density of the tufts of hair can be obtained and with which injection surpluses are avoided even at the same time. high injection pressures.
    The solution according to the invention to this problem consists in that the receiving plate is formed of at least two partial plates, the holes of the various partial plates respectively arranged one behind the other in the supply position having surface structures. different and / or different diameters and / or that in the supply position, a free space connected to the flow channel for the flow of gas or air is provided between the partial plates and this in the region of holes.
    Improved transport of tufts of hair is made possible by the structure of the receiving plate, which in turn allows for a higher packing density.
    Different diameters or different surface structures of the holes and in particular, a free space between the different partial plates through which the volume flow rate of the air or the suction gas is increased in the region of the receiving plate allow improved transport of tufts of bristles in the receiving plate with a constant flow of gas or air so that with constant power from the gas or air flow, tufts of bristles with higher packing density can be transported.
    To obtain an optimal passage of the tufts of bristles from a partial plate into the following partial plate, the holes of the various partial plates ideally have identical diameters or substantially identical diameters with a maximum gap of 0.1 mm.
    But it is also possible that the holes of a subsequent partial plate have diameters greater than the holes of the partial plate preceding this partial plate and that the holes of the following partial plate has input bevels.
    So that the tufts of bristles at the end of the transport path are held in a defined position in the receiving plate, it is appropriate that a bumper plate is provided as a stop for the tufts of bristles inserted into the holes of the plate. reception.
    The bumper plate may be movably mounted to change the distance between the bumper plate and the receiving plate. The suction force of the gas or air flow can be controlled by the distance between the receiving plate and the bumper plate. The more dense the filling ducts are filled with a tuft of hairs to be conveyed, the greater the distance between the receiving plate and the buffer plate to ensure a sufficient suction force.
    By bringing the bumper plate closer to the receiving plate until it is in contact with it, the tufts of bristles can again, after transport, be completely pushed back into the holes of the receiving plate, so that that the receiving plate with the tufts of bristles can be positioned against a subsequent treatment device.
    To bring the tufts of bristles to the receiving plate, the transport device may have at least one hollow duct for a tuft of bristles. The end of the outlet-side hollow duct and the receiving plate may be positioned relative to one another to fill all holes of the receiving plate with tufts of bristles one after the other.
    To allow faster filling of all the holes of the receiving plate with tufts of bristles, it is appropriate that the transport device has a number of hollow ducts adapted to the number of holes of the receiving plate. All holes can be filled at the same time. The different hollow ducts may also have on one side two or more duct sections to receive respectively a tuft of bristles from the stock of bristles, which meet on the outlet side in a larger common duct section to already fill larger individual holes in the receiving plate with a corresponding amount of pile filaments.
    There is a simple and inexpensive design structure when the hollow ducts are flexible hoses made of flexible material. In particular, flexible hoses made of plastics can be used.
    But the hollow ducts can also be tubular fittings made of steel, special steel or another metal. Flexible plastic hoses require a certain thickness of material to be able to withstand the pressure when transporting tufts by means of a flow of gas or air. It is possible to provide hollow metal ducts with a thickness of material and thus a diameter of smaller dimension so that they can be arranged on the end side closer to each other and the holes in the plate. reception can also be placed more closely. Because the receiving plate is smaller in overall size, the size of the device is reduced and allows for areas of bristles with tufts of bristles arranged closer to one another.
    An appropriate embodiment provides that the transport device has a support for the ends of the hollow conduits opposite the stock of bristles and a vacuum chamber which is disposed remotely to generate a vacuum, that the receiving plate can be arranged. between the support and the vacuum chamber and that the bumper plate is disposed inside the vacuum chamber.
    The tufts of bristles are then conveyed into the receiving plate by a suction flow generated in the vacuum chamber. The bumper plate against which the tufts of bristles abut and are thus held in a final position is provided so that the tufts of bristles remain in the receiving plate and are not sucked further into the vacuum chamber.
    Another embodiment provides that, to generate the flow of gas or air carrying the tufts of bristles, a compressed air generator and at least one vacuum suction nozzle cartridge disposed in the region of the carrier plate. reception are provided. This allows a simpler and cheaper design and operation of the design device.
    The space required for the device is significantly reduced, since compared to the previously described embodiment no vacuum chamber is required. Vacuum in the region of the receiving plate that generates the gas or air flow with which the tufts of hair are conveyed into the receiving plate is generated in a simple manner using suction nozzle cartridges under Vacuum available commercially through which compressed air is blown. The receiving plate with its partial plates has free spaces which allow the passage of a flow of gas or air from the holes to the suction nozzle cartridges under vacuum.
    To reduce the exhaust air noise, it is appropriate that a noise attenuation element be associated with the at least one vacuum suction nozzle cartridge. Such a noise attenuation element may in particular be disposed on the evacuation side in the region of a vacuum suction nozzle cartridge.
    To form tufts of bristles with a higher packing density, it is advantageous for a compression plate to be arranged downstream of the receiving plate, which has holes for receiving tufts of bristles and whose cross-section is smaller. that the cross section of the tuft of bristles brought into the relevant hole and that a device is provided for transferring the tuft of bristles from the receiving plate to the compression plate.
    When transferring tufts of bristles into the compression plate, the tufts of bristles are compressed per se, i.e., the entire tuft of bristles is somewhat reduced with respect to its outer circumference and the distance of the different hair filaments of a tuft of bristles relative to each other is thus reduced. Therefore, during the subsequent coating of the tufts of bristles with plastic to form a brush head or the entire brush body, one can work with a high injection pressure without the risk that the injection material is pushed through the tufts of bristles to the outside and that the brush is therefore unusable.
    It is appropriate for the compression plate to be placed downstream of a contouring plate, the contouring plate having holes, at least one of which is dimensioned to receive at least two tufts of bristles from the receiving plate and / or has a cross section diverging from the cross section of the corresponding hole of the receiving plate.
    The tufts of hair are transferred firstly from the receiving plate into the contouring plate where different tufts of hair can be grouped into a larger tuft of common hair or the tufts of hair can be provided with an outer contour special, for example oval or star-shaped, depending on the desired bristle area for the completed brush. Tufts of bristles deformed by means of the contour plate are then transferred into the compression plate where the tufts of bristles are compressed as previously described.
    It is possible that a transfer device is provided for transferring the tufts of bristles from the contour plate into the compression plate. After contouring the tufts of bristles in the contouring plate, the latter is moved in the region of the transfer device and the tufts of contoured bristles are transferred into the compression plate, for example by means of rods which can be inserted into the holes in the contour plate.
    Alternatively, the contouring plate and the compression plate may be arranged one behind the other in the longitudinal direction of the holes of the contouring plate and the device for transferring the tufts of bristles from the receiving plate into the Contouring plate can also be designed to transmit the tufts of bristles to the compression plate. The transfer of the tufts of bristles from the receiving plate into the contouring plate and thence into the compression plate takes place in a single operation, which allows the transfer to take place in a particularly rapid manner and allows a structure to be produced. compact and simple design of the device. The contouring plate can be designed in a particularly compact manner, since it must have in the longitudinal direction of the bristles a small extent to deform the tufts of hair but not so as to receive it by retaining them, since the tufts of bristles are directly transmitted by the contouring plate into the compression plate.
    It may be advantageous for the pile filaments to be trimmed or rounded on one side in the pile stock and the flat, unpaired or rounded ends of the pile filaments to be arranged forward in the conveying direction during transportation of the pile filaments. tufts of hair in the receiving plate.
    This allows the use of tufts of bristles whose useful end has already been treated before bonding with the brush body so that a treatment such as sharpening, rounding and / or grinding in the area of Finished bristle of the brush, which is often problematic, is no longer necessary. In order that the pre-treated ends of the pile filaments are not damaged during the transport of the pile tufts in the receiving plate and during the impact on the bumper plate, the pile filaments are oriented so that the flat ends are arranged at the front in the direction of transport.
    When transporting tufts of hair by means of a flow of gas or air into the receiving plate, it may happen that different pile filaments are transported faster than others, or during transfer into the plate of At the receiving end, different pile filaments can be held back so that pile filaments arranged offset from one another in the longitudinal direction can be in the receiving plate. In order to obtain tufts of newly arranged hairs without shifting in the longitudinal direction of the bristles in the receiving plate, it is appropriate that rods which can be inserted into the holes of the receiving plate are provided for gathering shifted filaments. relative to each other in the axial direction.
    Likewise, several tufts of bristles can be successively inserted axially offset from one another in a hole of the receiving plate, these tufts of bristles being collected, before transfer into the contouring plate or the compression plate. , by means of rods that can be inserted into the holes of the receiving plate. This also helps to increase the density of hair tufts of hair. It is also possible to successively insert different tufts of bristles, for example tufts of bristles of different colors, in a hole of the receiving plate, which are then combined into a tuft of common hairs multicolored.
    In order not to damage the treated ends of curly or rounded pile tufts on one side, it is appropriate for the rods to be inserted into the holes by the side of the receiving plate facing the flat ends of the pile filaments.
    The tufts of bristles can be transferred by means of a transfer device of the receiving plate, the contouring plate or the compression plate directly into a mold plate of an injection mold where they can be coated with of the plastic material to form a brush body or a brush head. Before coating the tufts of bristles, their ends on the attachment side may still be melted.
    To simplify the introduction of tufts of bristles in the plate in question, it is appropriate that the holes of the receiving plate, the contour plate and / or the compression plate respectively have a bevel on the insertion side.
    To allow hair areas comprising tufts of individual bristles obliquely, at least different holes of the compression plate may be arranged obliquely. It is thus possible to achieve more complex hair areas in which all the tufts of hair are not parallel to each other.
    The stock of bristles may have several feeds of material for different pile materials. For example, brushes with tufts of bristles of different materials or different colors can be made.
    When it is necessary to manufacture brushes with profiled bristle areas, it may be appropriate to provide a device for profiling the useful ends of the tufts of bristles. A profiling of the hair areas, after coating the tufts of bristles, by grinding a portion of the tufts of bristles, which requires additional grinding units and is associated with greater dust production, is not necessary. therefore not necessary.
    The device for profiling the useful ends of the tufts of bristles may have profiling rods or a profiling plate for acting on the useful ends of the tufts of bristles and a cutting device for cutting the opposite ends at the useful ends of the tufts of bristles. .
    Exemplary embodiments of the device according to the invention are explained below in more detail on the basis of the drawings.

A sectional representation of a receiving plate with a bundle of rods engaging in the holes of the receiving plate, FIG. 6 the arrangement according to fig. 5 with tufts of hairs gathered by the bundle of stems, fig. 7 is a sectional representation of a receiving plate with tufts of bristles transmitted to a contour plate and a compression plate, FIG. 8 a representation of a receiving plate with a bundle of rods engaging the holes of the receiving plate in the opposite direction with respect to FIG. 5, FIG. 9 the arrangement according to FIG. 8 with tufts of hair gathered by the bundle of stems, fig. 10 an arrangement similar to that of Figure 9 with tufts of bristles transmitted to an additional compression plate and FIG. 11 a device with tufts of bristles transferred from a compression plate into a mold plate of an injection mold.
    A device, designated in its entirety by 1, for producing hair areas for brushes has, according to FIG. 1, a stock of bristles 2 and a device 3 for taking individual tufts of hair in the stock of bristles 2 and a transport device 4 for transporting tufts of bristles 5 in holes 6 of a receiving plate 7 by means of a flow of gas or air.
    In a manner not shown, for example by means of an arcuate divider, individual tufts of bristles are taken from the stock of bristles 2 and are positioned by means of a tuft carrier 38 between a bottom plate 8 and a hose retaining plate 9, a tuft of bristles 5 being disposed in front of a hollow conduit 10 of the transport device 4 retained in the hose retaining plate 9.
    The tufts of bristles 5 are carried by the hollow ducts 10 in the direction of the arrow Pf1 in the holes 6 of the receiving plate 7. The receiving plate 7 is disposed between a support 11 supporting the ends of the hollow ducts 10 and a vacuum chamber 12 and is formed by two partial plates 13a, 13b.
    So that the tufts of bristles 5 are retained in the receiving plate 7, there is provided a bumper plate 14 as a stop for the tufts of bristles 5.
    In the schematic figures 1 and 2, the bottom plate 8 is disposed on the right and the tufts of bristles 5 are sucked to the left. In actual arrangements, the bottom plate 8 is generally down and the suction takes place upwards. Provisions in which the suction takes place downward are also conceivable.
    Parts of the tuft of bristles 5 can be locked on the entry bevel 15 of a hole 6 of the receiving plate 7. The tuft of bristles 5 is divided into two parts: The projecting tuft 5a which is against the bumper plate 14 and the tuft recessed 5b.
    Air is continuously extracted in the direction of the arrow Pf2 of the vacuum chamber 12 by the suction pipe 16. Air is thus extracted from the receiving plate 7 all around the bumper plate 14. By varying the distance between the stop plate 14 and the receiving plate 7, it is possible to control the amount of air that is extracted from the receiving plate 7.
    The distance between the receiving plate 7 and the bumper plate 14 is very important. When the distance is too small, the amount of air is not sufficient to pull all the filaments in the receiving plate 7. If the distance is too great, the filaments of the tuft of bristles 5a can be folded and sucked into the vacuum chamber 12.
    In the device 1 according to FIG. 1, the holes 6 of the partial plates 13a, 13b of the receiving plate 7 have diameters which are almost identical, but nevertheless have different surface structures to favor a division of the tuft of bristles 5 sucked in. a tuft of projecting bristles 5a and a tuft of recessed bristles 5b and thus obtain improved suction with reduced suction pressure.
    In the device 1 according to Figure 2, there is provided between the partial plates 13a, 13b of the receiving plate 7 a free space 18 connected to the flow channel 17 for the flow of gas or air. As a result, the volume flow rate of the air sucked into the interior of the receiving plate 7 can be increased and aspiration of the tufts of bristles 5 can thus be promoted.
    This effect is further reinforced by the additional hollow ducts 19 inside the partial plates 13a, 13b of the receiving plate 7.
    Figures 3 and 4 respectively show a detailed representation of a device 1 in the region of the receiving plate 7.
    Two vacuum suction nozzle cartridges 20 are disposed laterally inside the receiving plate 7. To these are connected on the compressed air side compressed air hoses 21 which are retained in the baffle plate 14 adjacent to the receiving plate 7. Each of the air exhaust nozzle cartridges has a recess 22 in the support 11 on the air evacuation side, on which a sound attenuation element 23 is in turn arranged. to reduce the operating noise.
    Compressed air is blown (arrow Pf3) into the vacuum suction nozzle cartridges 20 by means of a not shown compressed air generator. Due to the flow of compressed air flowing from the ejection nozzle 24 into the receiving nozzle 25, vacuum suction cartridge cartridges 20 and vacuum suction cartridge 20 are formed in the region of the vacuum connector 26. which carries with it the surrounding air. The vacuum connection 26 is connected with the free space 18 (FIG 3) or with the free spaces 18 (FIG 4) between the two partial plates 13a, 13b (FIG 3) or the three partial plates 13a, 13b, 13c (FIG 4) of the receiving plate 7 in which the holes of the partial plates 13a, 13b, 13c open.
    Due to the suction flow thus forming in the holes 6, the tufts of bristles 5 are sucked through the suction hoses, which are only shown in a sketched manner, in the receiving plate 7 where they divide as previously described in two tufts of partial bristles 5a, 5b and the tufts of front bristles abut against the bumper plate 14.
    The vacuum suction nozzle cartridges 20 respectively have in the region of their end of the longitudinal side a sealing ring 27 to ensure a sealing stop in the receiving plate 7 and prevent compressed air losses. It is also provided between the stop plate 14 and the receiving plate 7 and between the receiving plate and the support 11 unrepresented sealing elements.
    Compared with the embodiments according to FIGS. 1 and 2, no vacuum chamber 12 is necessary in addition to the vacuum generator in the embodiments according to FIGS. 3 and 4, which allows a structure of the entire device 1 which is not very cumbersome. , compact and cheap.
    In the embodiment according to Figure 3, the receiving plate 7 is formed by two partial plates 13a, 13b between which are provided a free space 18 and laterally enlarged cavities 19 for an optimized suction effect.
    In the embodiment according to Figure 4, the receiving plate 7 is formed by three partial plates 13a, 13b, 13c. There is provided between the first partial plate 13a and the second partial plate 13b a narrow free space 18a which opens laterally into the flow channel 17 in which is placed the vacuum suction nozzle cartridge 20. It is also provided between the second partial plate 13b and the third partial plate 13c a narrow free space 18b which laterally converts into an enlarged cavity opening into the flow channel 17 and an optimized suction effect is thus also obtained. There is further provided an additional free space 18c between the third partial plate 18c and the bumper plate 14.
    The main flow of the air flow can be influenced by the dimensions of the free spaces 18, 18a, 18b, 18c. In an embodiment according to FIG. 4 for example, the free space 18 a between the first partial plate 13 a and the second partial plate 13 b and the two other free spaces 18 b, 18 c respectively have a thickness of 0.2 mm. which the main flow of the air flow passes over the free space 18a.
    Fig. 5 shows a receiving plate 7 comprising two partial plates 13a, 13b, which rests against a counterplate 28 and on which is disposed on the upper side a bundle of rods comprising a rod guide plate 29, individual rods 30 and a rod support 31.
    The tufts of bristles 5a and 5b are gathered into a complete tuft of bristle by lowering the stems 30 and are thereby compressed, see FIG. 6. A vibration of the counter plate 28 can facilitate this process.
    The tuft of bristles 5 shown on the outside on the right in FIGS. 5 and 6 has a greater diameter than the other tufts of bristles. This larger tuft of bristles may for example, according to Figures 1 and 2, be composed of two smaller tufts of bristles 5 from the stock of bristles 2 by means of a hollow duct 10a branched in a Y-shape.
    The suction hoses 10, 10a of the device 1 according to Figures 1 and 2 are flexible hoses of flexible material, which allows a simple and flexible mounting and is cheap. Safe and reliable transport of tufts of hair 5 is nevertheless guaranteed.
    In FIG. 7, a receiving plate 32 and a compression plate 33 in which the tufts of bristles 5 are transferred by means of the rods 30 are arranged downstream of the receiving plate 7. The contouring plate 32 has holes 34 a hole 34a is dimensioned to receive two tufts of bristles 5 of the receiving plate 7. It is thus possible to obtain areas of bristles comprising areas of partial bristles of different sizes, for example regions with sections of bristles stretched lengthwise.
    The tufts of bristles 5 are directly pushed from the contouring plate 32 into a compression plate 33. Its holes 35 have respectively a cross-section which is smaller than that of the corresponding hole 34 of the contouring plate 32. The density of bristles tufts of bristles 5 are thereby increased, i.e., the individual filaments of the bristle tufts 5 are closer to one another and have a smaller distance from one another. It is thus avoided that, during the subsequent coating of the fastening ends of the tufts of bristles, plastic material is pressed between the individual filaments even at higher injection pressures and the brushes are thereby unusable.
    The individual rods 30 form with the rod support 31 and the rod guide plate 29, according to Fig. 7, a common device for transferring the tufts of bristles 5 from the receiving plate 7 into the contour plate 32 and the plate. compression 33.
    Alternatively, it is possible for the tufts of bristles 5 to be initially transferred from the receiving plate 7 into the contour plate 32 and the contour plate 32 to be subsequently moved to another treatment station where the tufts of The bristles are transported by a separate transfer device into the compression plate 33.
    When hair filaments already trimmed on one side are held ready in the stock of bristles 2, it is appropriate that they are arranged during transport in the receiving plate 7 with their flat end 36, unspecified, forward in the direction of transport, so be sucked through the hollow conduits 10 with their flat end 36 forward (Figure 1). The pointed ends 37 of the pile filaments of a tuft of bristles 5 are therefore not damaged during the impact of the tuft of bristles 5 on the abutment plate 14.
    In order also to avoid damage to the end-pieces 37 during subsequent treatment of the tufts of bristles 5, the tufts 5a, 5b in the partial plates 13a, 13b of the receiving plate 7 according to FIGS. 8 and 9 can be collected by the side of the receiving plate 7 opposite to the embodiment according to Figures 5 and 7. For this purpose, the rods which are also arranged on a rod support 31 and are guided in a rod guide plate 29 are introduced , according to FIG. 8, from below in the holes 6 of the receiving plate 7 so that the pile filaments of the pile tufts 5a, 5b are subjected to the action of these rods on their flat end 36. By introducing further ahead the stems 30 in the holes 6, the partial bristle tufts 5a, 5b are gathered together into a compressed tuft of bristles 5 (FIG. 9). A counterplate 28 covering the holes 6 prevents the tufts of bristles 5 and the individual filaments from coming out.
    According to FIG. 10, the tufts of bristles 5 are then pushed into a compression plate 33. The holes 35 of the compression plate 33 have respectively a smaller diameter than the corresponding holes 6 of the receiving plate 7 so that the tufts of bristles are compressed in themselves during transport in the compression plate 33. To allow a simple introduction of the tufts of bristles 5 in the compression plate 33 and avoid damage to the tips of the ends 37 tufts of bristles 5, bevels 39 are provided on the insertion side on the holes 35 of the compression plate 33.
    According to FIG. 11, the tufts of bristles 5 are transferred from the compression plate 33 into a molding plate 40. For this purpose, the flat ends 36 of the tufts of bristles are again subjected to the action of the rods 30 and expelled. of the compression plate 33.
    The molding plate 40 with the tufts of bristles 5 placed therein can be transferred into an injection mold where the flat ends 36 of the tufts of bristles are coated to form a brush body or a brush head.
    A profiling of the tufts of bristles 5 may possibly take place before the transfer of the tufts of bristles into the molding plate 40. This may take place for example by means of profiled rods insertable in the compression plate 33 and against-stops corresponding.
    Prior to coating the flat ends 36 with tufts of bristles 5, these may also be melted to improve the hold of the individual pile filaments and to reliably prevent excess injection of injection material between the pile filaments.
