    [0001] This registration application claims the benefit of US Provisional Registration Application No. 61 / 389,963 filed on October 5, 2010 and US Provisional Registration Application No. 61 / 523,528, filed on August 15, 2011, whose publications are hereby incorporated by reference in their entirety. Foundations
    [0002] In the art, devices are known which generally work to provide a thread around an article.
    [0003] As an example, US Patent 5,505,504 discloses an apparatus that includes a mechanism for forming a U-shaped loop of a mooring wire, a mechanism for guiding the U-shaped loop for winding it around an outer surface of a portion of the article to be tied, a mechanism for twisting the closed end and the other end of the U-shaped loop, and a mechanism for cutting a tie wire at an appropriate time, at an appropriate length.
    [0004] As an additional example, U.S. Patent 6,279,970 describes an automatic knot tying device for tying a discrete knot around an article, such as, for example, a yarn roll. The device works by pulling a filament transversely around the article, and includes a hand housing, and a mechanism for tying a knot inside the housing, comprising an empty nozzle for locating the filament towards the article, a ring for winding the filament around the article, and a plurality of pins that extend inward and retract out of the filament path to form the knot. The operation is completed with the tightening and cutting of the loose filament, so that the resulting knot is discrete and secure.
    [0005] U.S. Patent 6,648,378 also describes an automatic knot tying device for tying a discrete knot around an article, such as, for example, a roll of yarn. The device operates by pulling a filament, such as the FAA approved loop, transversely around the article. The device includes a hand-held housing and a knot-binding mechanism within the housing, comprising a plurality of carriage rings, to wrap the filament around the article, at least one shuttle to move the filament between the locking mechanism rings transport and along the article, in appropriate steps, and a plurality of hooks to pull the filament away from the article, in appropriate steps. The operation is completed with tightening, cutting and reloading, so that the resulting knot is discrete and secure.
    [0006] Although the devices described in these publications, which are incorporated herein by reference in their entirety, generally work for their intended purposes, an improved knot tying device and a cartridge system to provide the filament to the same. summary
    [0007] An improved device for knot tying and a cartridge system to provide a filament for it are described hereinafter, such as, for example only and without limitations, a multiple strand loop, a single cord loop, FAA approved loop, etc.
    [0008] For example, the knot-binding device may include a pair of rings (which are preferably separate) that surround the article, with each pair of rings having a continuous channel formed in them, the channels of each pair of rings being located opposite each other, a shuttle that can be attached to the filament (the assembly of which may include a filament feeding mechanism, as well as a grabbing mechanism), the shuttle being moved during a lashing process of the node and within the channels of each pair of rings, and thus around and along a section of the article, for example, by the use of selectively driven electromagnets, and at least one hook to pull the filament away from the article, at appropriate times, during the knot tying process.
    [0009] The knot tying mechanism may alternatively include a shuttle, adapted to reliably grasp the filament, the shuttle moving in a circular path in a plane forming a single knot, and a device for pulling the knot. filament away from the article, at appropriate times, during the knot tying process and to rotate the filament to thereby form loops through which the shuttle, carrying the filament, is passed.
    [0010] The cartridge, preferably, has a housing that is dimensioned and arranged to be fixed releasably to the knot's mooring device. The housing has an opening, through which the pre-cut, or loosely coupled sections of the filament can be pulled.

    [0041] In many industries, both military and commercial, such as the aircraft, automotive and appliance industries, cable or harness packages are used extensively in the manufacturing processes of their various products. Each bundle, or harness, usually comprises two or more threads that are usually tied together at various points along their lengths to help ensure safety and durability, as well as a generally clean design. The knot tie device in question and the cartridge system for providing a filament for it, in particular, for loops approved by the FAA and / or for military purposes, work to allow the operator to tie the necessary knots around these articles.
    [0042] Turning now to the Figures, illustrated in Figures 1 - 13 there is an exemplary knot tying device 10. Preferably the knot mooring device 10 is incorporated into a housing (not shown, for the sake of clarity) and dimensioned and configured to allow the device to be carried by hand and operated. As will become clear, the knot tying device 10 can be used to tie a filament 12 around an article 14, such as a yarn roll. Filament 12 is supplied to the knot tying device 10 from a user-replaceable spool 16, which can be mounted on the device, as shown in Figure 1, or, in an additional embodiment, the filament can be supplied for the knot tying device 10, from a user replaceable cartridge 18, which can also be mounted on the device, as illustrated in Figure 10 and described in greater detail hereinafter.
    [0043] To tie a knot around an article 14, the knot tying device 10 includes a shuttle assembly carrying a filament 20 (to which filament 12 is fed from the dispatch device of filament 16/8 being used), a pair of sets of rings 22 and 24 facing opposite sides, that is, the right and the left, between which the shuttle set 20 is displaced while loading the filament 12, and a set of loop hook 26 which works to pull filament 12 during operation away from article 14, in order to provide openings through which the shuttle set 20 will pass, in order to create knots - as illustrated by way of example in the Figures 14A-14L. The shuttle assembly itself may include a feeding mechanism to assist in moving filament 12 to a gripping mechanism that is used by the shuttle assembly to load filament 12.
    [0044] To move the shuttle set 20 around the outer surface of article 14 and between the sets of rings 22 and 24, that is, through article 14 and, more specifically, to move the shuttle set 20 between and within of the channels 28 that are formed in the sets of rings 22 and 24 (channels 28 which, preferably, have a depth so that, when the shuttle set 20 is inside the channel of one of the sets of rings 22 and 24, the set of shuttle 20 will be freed from the channel of the other of the channel sets 22 and 24 - the depth of the channel can be sufficient at least to ensure that the shuttle will not fall out of the channel); each of the sets of rings 22 and 24 is provided with a plurality of electromagnetic coils that, when selectively activated, work to attract (or repel) and thus direct the movement of the shuttle set 20, as desired, to perform the steps of tying the knot. Electromagnetic coils can be incorporated within the channels of ring sets 22 and 24, can be positioned adjacent to, or outside the back surface of ring sets 22 and 24, or similar positions, without limitations. As will be noted, the shuttle assembly 20 is therefore preferably constructed of a ferrous material (possibly even an electromagnetic material) to allow the shuttle assembly 20 to be pulled into (or repelled by) one or more of a plurality of electromagnetic coils that are currently being driven. Although not required, ring sets 22 and 24 are preferably constructed from a non-ferrous material. In any case, ring sets 22 and 24 are preferably constructed from a durable material that should show minimal friction when the shuttle set 20 is being pulled, and within channels 28 of ring sets 22 and 24. As will still be observed, the knot mooring device 10 will include a processor and associated instructions, to selectively drive the plurality of electromagnetic coils in a given sequence, in order to, in this way, cause the shuttle set 20 to be moved to the around article 14, as desired, to form a given knot. The processor and associated instructions can also be used to control other mechanisms, such as motors, actuators, solenoids, etc., of the knot-tying device 14, as can be readily observed. In this way, the knot mooring device 10 can be supplied with energy, for example, from a battery, from a wall socket, etc., to supply electrical energy to the processor, any motors, actuators, solenoids, etc. . In certain circumstances, it will also be noted that other sources of energy, such as pneumatic energy, can be used to drive any moving / actionable parts described herein.
    [0045] In yet another embodiment, to move the shuttle set 20 around the outer surface of article 14, and between sets of rings 22 and 24, one or more electromagnets 60 (which can be selectively driven, as necessary to move the shuttle set) can be mounted on an additional driven plate 62, with, for example, a gear that is positioned adjacent to the outside of the back side of each of the sets of rings 22 and 24. As you go be observed, the driven plate 62, an example of which is shown in Figures 15 and 16, can be controlled to rotate around the article 14, in order to make the electromagnet (s) 60 rotate ( m) around article 14, this electromagnet (s) 60 which, when selectively actuated, causes the shuttle set to be moved within and between stationary sets of rings 22 and 24. In addition, to allow the article to be fed into the device, the driven plate 62 may include an opening, such as that illustrated in Figure 15, which can be separable, in the same way as ring sets, or the like, without limitations. In addition, still, the driven plate 62 can load one or more against weights 64, as necessary, to balance the driven plate 62 during its rotation.
    [0046] To allow the article 14 to be placed inside the knot mooring device 10, the sets of rings 22 and 24 can be made so that they can be separated. By way of example only, the sets of rings 22 and 24 may comprise a lower half and an upper half, the upper half being movable in relation to the lower half in order to create a space in which the article 14 can be inserted. For this purpose, the rear ends of the upper half of the ring sets 22 and 24 can be pivotally connected 30 with the device housing (as, in this example, the lower half of the ring sets 22 and 24, being fixed in the housing device) a motor, or similar connection for drive 32 - which can be operated by trigger - being later coupled with the upper half of the sets of rings 22 and 24, the connection for drive 32 being mobile, to make the upper half of ring sets 22 and 24 are opened and closed in relation to the lower half of ring sets 22 and 24. While this describes a way to open and close ring sets, that is, to create a separation between the halves of ring sets, it should be noted that alternatives can be used, such as making the bottom half of ring sets 22 and 24 mobile, with the top half of ring sets 22 and 24 being fixed, making both halves of ring sets 22 and 24 mobile, in similar ways. Once the article 14 has been placed inside the knot mooring device 10, for example, that the sets of rings 22 and 24 have been opened to create a space within which an article 14 is positioned, a set for fastening actuated 34 can be lowered onto the article 14 to thereby secure the article within a position within the ring sets 22 and 24.
    [0047] In order to apply tension to filament 12 during the knot tying process, an activated tension mechanism 36 is provided. In the illustrative example, the tensioning mechanism 36 comprises an arm 38 which is pivotally attached to the housing, and a hook 40 which is rotatably attached to the arm 38. During the knot tying operation, the arm 38 of the locking mechanism tension 36 can be driven so that it is lowered into an area between sets of rings 22 and 24, in which the hook can be driven to rotate and fit around filament 12, when filament 12 reaches the space between the sets of rings 22 and 24. Alternatively, the tension mechanism 36 can be operated to be lowered into an area between the sets of rings 22 and 24, and the hook can be operated to rotate with filament 12, and then passed on the hook. After the filament 12 has been secured by the hook, in one of these ways, the arm 38 can be actuated to be suspended in order to provide tension in the filament 12. As the knot tying operation proceeds, a spring, induced by torque motor, or similar, associated with tension mechanism 36 will work to maintain the tension of filament 12. After the knot tying operation has been completed, arm 38 can be driven back, into the area between the sets of rings 22 and 24 (if necessary), and the hook 40 activated to rotate, in order to, in this way, release or detach the filament 12 of the tension mechanism 36.
    [0048] It can also be seen that the tension mechanism can be displaced tangentially to the set of rings 22 and 24, to provide a tension for the filament 12. In the preferred embodiments, the tension that the device applies to the filament used to package the wires can be defined by the user.
    [0049] As with the tensioning mechanism, the loop hook assembly 26 comprises at least one hook 42, which must be driven in and out of the area between the ring assemblies 22 and 24, to secure and release / detach the filament 12, when necessary, to create the space in which the shuttle set 20, while carrying the filament 12, can pass through, in this way, to create the desired knot. In addition, you may want the loop hook set 26 to be movable tangentially to the ring sets 22 and 24. To do so, the hook 42 can be mounted on a powered rack and pinion set, as is specifically shown in Figures 16A and 16B. The hook 42 can also be actuated to rotate, to further provide the fitting of and the release / disengagement of the filament 12.
    [0050] For cutting the filament 12 after a knot has been tied around the article 14, by the knot tying device 10, a lining mechanism 44 is provided. As an example only, the packing mechanism 44 comprises a fixed blade and a movable blade, between which the filament 12 is positioned. Then, to cut the filament 12, the movable blade is activated to be displaced in relation to the fixed blade, and the two blades will close on the filament 12. In the example trim mechanism illustrated in Figure 9, the movable blade is activated to be moved, using a rack or pinion set. As will be seen, other assemblies / mechanisms to move the movable blade and / or to secure filament 12 can be employed, without limitation.
    [0051] To feed the filament 12 into the shuttle assembly 20, with which a mechanism associated with the shuttle assembly will work to grip the filament 12, a feed assembly 46 is provided. In the exemplary embodiment, the supply set 46 comprises a pair of driven bearings. Note that other mechanisms capable of carrying out this function can also be employed.
    [0052] As noted above, in an additional embodiment of the knot mooring device 10, a cartridge 18, comprising an enclosure and an opening through which the filament must be pulled, can be used to supply the filament to be tied up. In this sense, the cartridge 18 can be removably inserted into the knot mooring device 10, for example, being adjusted by snap, adjusted by sliding, mounted later, or in a similar way, with the device that houses it, and can if desired, include predetermined portions of the filament 12. In one embodiment, the predetermined portions of the filament may be loosely coupled with each other, so that, once the first strand of the filament is pulled into the anchoring device of knot 10 and used to tie a knot, the additional strands of filament are continuously pulled into the knot mooring device 10; that is, they will follow the stretch of filament previously pulled, until the supply of the strands of filament has been exhausted. This loose coupling of the ends of the strands of the filaments can be accomplished through the use of adhesives, struts of a total length of the filament, providing a perforated guide between the strands of the filament, or similar means without limitation. In such an embodiment the strands of filament can be placed inside the cartridge, in a ventilated or stacked relationship, as illustrated in Figure 11. Although not required, a spring or similar mechanism can be provided to deflect the strands of filament in direction, in the example shown, to the bottom of the cartridge, into which an opening is located, from which the strands of filament are then pulled. It is desirable that these cartridges 18 are refillable. It can also be seen that these strands of filament can be provided by a spool 16.
    [0053] In an additional embodiment, the strands of filament are pre-cut (which may include guides) and are intended to be removed from cartridge 18 at once.
    [0054] To move the strands of filament from the cartridge 18, to the shuttle set 20, for example, the first strand of filament, in the case of loosely attached strands of filament, or each strand of filament, in the case of stretches of pre-cut filament, a feed assembly 50 is provided. In the illustrated example, the feeding set 50 comprises a driven element 52, which is adapted to grasp one end of each exposed filament section, that is, accessible through the opening 54 in the cartridge 18, through which the driven element 52 is driven , to load the strand of filament attached to the shuttle set 20, for collection by the same. For this, the driven element 52 can be loaded on a rack and a pinion set, as illustrated. It should be understood, however, that other mechanisms can be used to move the driven element 52 from the cartridge 18 to the shuttle assembly 20, without limitations.
    [0055] It should also be noted that, if filament 12 has strands of filament pre-cut, or loosely coupled, a trim mechanism may not be necessary.
    [0056] Turning now to Figure 17, an additional exemplary knot mooring device is illustrated. In general, device 10 ', shown in Figure 17, includes a shuttle carrying a filament 2600, which is moved in a circular path, around a roll of yarn 2602, and at least one device 2604 (from which two are illustrated) to release the filament releasably away from the yarn roll 2602 at appropriate times during the knot-tying process, and to rotate the filament to form loops through which the 2600 shuttle is passed, during the knot tying process. During the knot tying process, the 2600 shuttle will move along the circular path in a single plane, which is generally transversal to the yarn roll. The filament is fed to the 2600 shuttle by a 2602 filament feed device.
    [0057] To move the 2600 shuttle in any direction along the circular path, the 2600 shuttle is provided with an external toothed surface, which is adapted to be driven by correspondingly toothed gears driven 2608, as is further illustrated in the Figures 18 and 19. When the 2600 shuttle is driven by the 2608 drive gears, the shuttle is additionally supported by 2610 bearings. As can be seen, the number of 2608 drive gears and 2610 bearings can be varied as needed , depending, for example, on the size of the 2600 shuttle.
    [0058] To drive the drive gears 2608 and thus make the shuttle 2600 move around the circular path, the drive gears 2608 can be mounted on an oscillating plate 2612, as shown in Fig.20. The oscillatory plate 2612 is driven by a drive gear 2616, the oscillatory movement of the oscillatory plate 2612 is transferred to the drive gears 2608, by means of an eccentric pin 2614 and to a drive shaft 2615. More specifically, when the oscillating plate 2612 oscillates, the eccentric pin 2614 is rotated, and the drive shaft 2615 attached to it, rotates in the same way, to drive the drive gear 2608 attached to it. The drive gear 2616 can be driven by a chain, belt, gears or similar means that would be coupled to a motor. Alternatively, the drive gears 2608 can be made to rotate by being directly coupled to a motor, without using the oscillatory plate mechanism described, being driven, for example, by a chain, a belt, gears or similar means.
    [0059] To tie a knot around a roll of yarn 2602, the shuttle 2600 is moved to move on hook 2618 or to hook device 2604, with device 2604 (and hook 2618) being pulled retract, this is to be moved away from the yarn roll 2602, in order to form a loop, as shown in Figure 21. To do so, the device 2604 is mounted on a support 2620, which is adapted to move laterally with respect to the yarn roll 2602 and rotating. As is further illustrated in Figures 21A to 21 D, the support 2620 is specifically rotated, in order to orient the loop at an angle relative to the circular path, followed by the 2600 shuttle to thereby allow the 2600 shuttle to pass through of the loop and, thus, under the filament, as maintained by the hook 2618. The support 2620 can be rotated, both clockwise and counterclockwise, to create loops through which the hook 2600 can pass, by being moved in the direction clockwise and counterclockwise, respectively. Once the shuttle 2600 has been moved through the loop, the hook 2618 can be moved to release the filament, the filament being pressed against the yarn roll 2602, for example, by an additional movement of the 2600 shuttle To provide the hook 2618 with one movement, the hook 2618 is pivotally mounted in the housing 2622, which is loaded by the support 2620, within which is located a switching device, used to pull, or push, the hook 2618 , in relation to the housing 2622 in order to move the hook 2618 between a filament locking position and a filament release position, as shown in Figures 22A and 22B, respectively.
    [0060] To additionally control the position of the filament during the knot tying process, the 2606 system, which is used to feed the filament to the 2600 shuttle, can also be rotated in a plane that is generally transversal to the circular path the shuttle 2600. More specifically, as shown in Figures 23A and 23B, the system 2606 can be rotated in a first direction, for example, in the right direction, shown in Figure 23A, in order to make the filament is applied on the right side of the area in which the knot is being formed, and the system 2602 can be rotated in a second direction, for example, on the left, as shown in Fig. 23B, in order to make the filament is applied on the left side of the area in which the knot is being formed. In addition, as shown in Fig. 24, a positioning pin 2626 can be provided to engage with the knot being formed, when the filament is being tightened, to thereby prevent the knot from being displaced from the mooring location from the knot when, for example, the 2600 shuttle is being moved to tighten the filament around the yarn roll 2602.
    [0061] Preferably, the positioning pin 2626 is arranged on a mobile device, so that the pin 2526 can be retracted, or, on the other hand, moved out of the socket with the filament, during the moments when the device is being used to form the knot, or even to wrap the yarn roll 2602. Positioning pin 2626 is also preferably arranged to provide a force on the knot in a direction that is generally tangential to the yarn roll 2602 at the node points.
    [0062] To insert and remove the yarn roll 2602 from device 10 ', device 10' is provided with an opening. To facilitate the movement of the shuttle 2600, in the circular path during the knot tying process, the opening is preferably closed (totally or partially) by a movable door 2682, as shown in Figures 25A and 25B. The movable door 2628 can therefore include additional drive gears 2630, and a support structure 2632 (which may be bearings, a surface, or the like) to move and support the shuttle 2600 through the movable door 2628. In a preferred embodiment the movable door 2628 has an integrated gear train to drive the drive gears 2630, which gear train can be coupled with the same devices that work to drive the drive gears 2616. As can be seen , an additional drive mechanism will be provided to move the movable door 2628 in and out of a position relative to the opening of the device 10 '. In a further embodiment, illustrated in Figure 26, the movable door 2628 does not need to be provided since the shuttle 2600 is dimensioned to reach the gap created by the opening of the device 10 ’. Specifically, in such an embodiment, the 2600 shuttle will have a length that ensures that when the 2600 shuttle reaches the gap created by opening the device 10 ', the 2600 shuttle will be engaged with at least one of the 2608 drive gears .
    [0063] To hold a roll of yarn 2602 in the proper position, when inserted into device 10 ', device 10' may additionally include a device for securing package 2630. The device for securing package 2630 includes a retractable arm 2632 , having a portion for fitting the 2634 package at one end of it. The retractable arm 2632 can be driven, for example, by using a 2632 motor, having a transmission shaft that carries a worm gear 2638 that , in turn, drives a toothed gear 2640, which fits with a corresponding tooth formed on the retractable arm 2632. The retractable arm 2632 and, thus, the fitting portion of the package 2634, can thus be actuated to, or retracted from the yarn roll 2620, by means of a clockwise and counterclockwise rotation of the worm gear 2638, coupled with the motor transmission shaft 2632. The retractable arm 2632 is preferably arcuate in shape, and thus , d in an arc, as shown in Figures 27A and 27B, in order to allow a fitting portion of the 2634 bundle, precisely shaped, to properly secure and orient the bundles of 2620 yarns of various sizes, against the bottom wall 2642 of the housing, which also has an arcuate shape, in the vicinity of device 2604, that is, the location of the neighborhood from which the node is being formed. Since the device 10 'can accept bundles of yarn 2602 of various sizes, the device 10' can be equipped with an additional device, which works to stop the rotation of the arm 2636 (to allow the arm 2632 to slide against the force of motor 2636), when the retractable arm 2632 presses a roll of yarn 2602 firmly against the back wall 2642
    [0064] For more accurate filament feeding on the 2600 shuttle, the 2602 feeding device is arranged so that it can be retracted into and away from the 2600 shuttle. For this purpose, as shown in Figure 28, the 2606 feeding device can be retracted. provided with a motor 2644, and associated drive mechanism 2646, to drive the feeding device 2606 towards and away from the 2600 shuttle; on arrival at the shuttle 2600, the front end of the feeding device 2606 will work to separate the gripping elements 2648 deviated from the shuttle device 2600, to position the filament between the gripping elements 2648, whereby the feeding device 2026 being retracted, the gripping elements 2648 will close over the fed filament, and grasp the filament for displacement, by moving the 2600 hook. The gripping elements 2648 can be pivotally mounted on the 2600 hook, and can be deflected, to close on each other using a spring or similar means.
    [0065] As will be appreciated, the movement of the various mobile elements of the device 10 'can be controlled by means of a controller having associated instructions and, by the controller, the elements of the device 10' can be moved in several different ways, to make the arrangement 10 'to tie several different types of knots around bundles of yarn 2602.
    [0066] As previously described, device 10 'can also carry a disposable spool, or a 2650 cartridge that carries a stretch of filament for tying knots around one or more bundles of yarn 2602, as shown in Figure 29. In addition hence, the device 10 ', which can be held in hand, may include a shoehorn type arm 2652, for use in guiding the wire roll 2602 into the opening of the device 10', as shown in Figure 30. [0067] Although specific embodiments of the object of the invention have been described in detail, those skilled in the art will note that various modifications and alternatives to details can be developed in the light of the set of teachings in this publication. For example, it should be noted that the programming can allow the control of the elements to, in this way, tie one of the multiple different types of nodes, types of nodes these, to be tied that can be selected by the user. In this way, the specific arrangements that have been disclosed should be taken only as illustrative and not limiting the scope of the invention, which should be given a wide scope by the appended claims and their equivalents.
