DETAILED DESCRIPTION

In many industries, both military and related to commercial activities, for example, in the aviation industry, in the automotive industry and in the instrument-making industry, bundles or wire harnesses are widely used in the manufacturing processes of various products. Each bundle or bundle usually contains two or more wires, which are usually connected to each other at different points along their length to help ensure reliability and durability, as well as, generally speaking, for the convenience of design. A knotter device and a system with a cartridge for supplying a binding thread, in particular, a cord approved by the United States Federal Aviation Agency (FAA) and / or the military, which are the subject of the invention, operate in such a way that they allow the operator to tie the required knots around such products.

Turning now to the consideration of the drawings, in FIG. 1 - FIG. 13 shows an exemplary knotter 10. Preferably, the knotter 10 is integrated into the casing (not shown for clarity) and is sized and configured to allow manual transport and manual control. Obviously, the knitting device 10 is suitable for tying the yarn 12 around the product 14 to be strapped, for example, around a bundle of wires. The thread 12 is fed into a knitting device 10 with a user-replaceable spool 16 installed in the device, as shown in FIG. 1, or in yet another embodiment of the invention, the yarn 12 can be fed to the knitting device 10 from a user-replaceable cartridge 18, also installed in the device, as shown in FIG. 10 and in more detail below.

To tie a knot around the product 14, the knot device 10 comprises a shuttle assembly 20 transporting the thread (to which the thread 12 is fed from the used thread feeding device 16/18), a pair of nodes 22 and 24 facing in the opposite directions, i.e., left and right the shape of the rings between which the shuttle assembly 20 moves during the transportation of the yarn 12, and the loop-forming hook assembly 26, the function of which is to pull the yarn 12 during operation from the product 14 to thereby create holes through which the shuttle assembly 20 passes, for I create, thereby, nodes, such as, for example, those nodes that are shown as examples only in FIG. 14A - FIG. 14L. The shuttle assembly itself may include a feed mechanism to help move the yarn 12 into the pickup mechanism, which is used by the shuttle assembly to transport the yarn 12.

To move the shuttle assembly 20 around the outer surface of the product 14 and between the nodes 22 and 24 in the form of rings, that is, across the product 14, and, in particular, to move the shuttle assembly 20 between the grooves 28 and inside the grooves 28 that are formed in the nodes 22 and 24 in the form of rings (in which the grooves 28 preferably have such a depth that when the shuttle assembly 20 is inside the groove of one of the ring-shaped nodes 22 and 24 of the rings, the shuttle assembly 20 completely leaves the groove of the other of the nodes 22 and 24 in the form of rings , the depth of the groove in which may be at least dos sufficient to ensure that the shuttle is not guaranteed to fall out of this groove), each of the rings-shaped assemblies 22 and 24 is equipped with a corresponding set of electromagnet coils that, when selectively actuated, operate in such a way that they attract (or repel), and, thereby controlling the movement of the shuttle assembly 20 in a desired manner to perform knotting operations. Electromagnetic coils can be embedded inside the grooves of the ring-shaped nodes 22 and 24, can be located adjacent to the rear outer surface of the ring-shaped nodes 22 and 24, and the like, but these examples are not limiting. Therefore, it is understood that the shuttle assembly 20 is preferably structurally made of ferrous metal (possibly even magnetic material) to enable the shuttle assembly 20 to be attracted to one or more electromagnetic coils of the plurality of electromagnetic coils currently actuated (or its repulsion from them). The nodes 22 and 24 in the form of rings are preferably made of non-ferrous metal, although this is not a prerequisite. In any case, the nodes in the form of rings in the form of rings 22 and 24 are preferably made of durable material providing minimal friction when the shuttle assembly 20 is held between the grooves 28 of the rings-shaped nodes 22 and 24 and inside them. In addition, it is understood that the knotter 10 comprises a processor and corresponding instructions for selectively driving a plurality of electromagnetic coils in a predetermined sequence, thereby causing a desired movement of the shuttle assembly 20 around the article 14 to create the desired assembly. It is easy to understand that the processor and corresponding commands can also be used to control other mechanisms, such as, for example, electric motors, drives, solenoids, etc., of the knotting device 14. Accordingly, electricity can be supplied to the knotting device 10, for example, from a battery , wall outlet, etc. for supplying power to the processor, any electric motors, drives, solenoids, etc. It is also understood that, under certain circumstances, other energy sources, such as, for example, pneumatic energy sources, can be used to drive any of the movable / driven components described herein.

In another embodiment, to move the shuttle assembly 20 around the outer surface of the article 14 and between the nodes 22 and 24 in the form of rings, one or more electromagnets 60 can be installed (with the possibility of selectively actuating them as necessary to move the shuttle assembly) on an additional driven plate 62, such as, for example, a gear wheel, which is located near the rear outer side of each of the nodes 22 and 24 in the form of rings. It is understood that control of the driven plate 62, an example of which is shown in FIG. 15 and FIG. 16, can be implemented in such a way that it rotates around the product 14, thereby causing the rotation of the electromagnet (electromagnets) 60 around the product 14, and this electromagnet (these electromagnets) 60, when it is selectively brought into action, causes (cause) ) the movement of the shuttle assembly inside the fixed assemblies 22 and 24 in the form of rings and between them. In addition, to enable the product to be fed into the device, the driven plate 62 may include an opening similar to that shown in FIG. 15, which may be detachable like ring-shaped assemblies, and the like, but these examples are not limiting. In addition, if necessary, the driven plate 62 may contain one or more counterweights 64 for balancing the driven plate 62 during its rotation.

To ensure the possibility of placing the product 14 in the knitting device 10, the nodes 22 and 24 in the form of rings can be made detachable. Just as an example, the ring-shaped assemblies 22 and 24 may comprise a lower half and an upper half, the upper half being movable relative to the lower half, thereby creating a space into which the article 14 can be inserted. For this, the rear parts of the upper half knots 22 and 24 in the form of rings can be connected 30 to the casing of the device with the possibility of rotation (in this example, the lower half of the nodes 22 and 24 in the form of rings is attached to the casing of the device) lever transmission 32 driven by an engine, etc. to The opening can be controlled by a starting device, and it is additionally connected to the upper half of the ring-shaped nodes 22 and 24, while the slave linkage 32 can move so that the upper half of the ring-shaped nodes 22 and 24 are opened and closed relative to the lower half of the nodes 22 and 24 in the form of rings. Despite the fact that one method for opening and closing nodes in the form of rings is described here, that is, creating a gap between the halves of the ring-shaped node, it is clear that alternative options can be used, for example, causing mobility of the lower half of the nodes in the form of rings, 22 and 24, with of this, the upper half of the ring-shaped nodes 22 and 24 is stationary, causing mobility of both halves of the ring-shaped nodes 22 and 24, and the like. After the product 14 is placed inside the knitting device 10, for example, after the nodes 22 and 24 in the form of rings have been opened to create the space in which the product 14 is placed, the driven clamping device 34 for fixing can be lowered onto the product 14, thereby, the articles are in the proper position inside the ring-shaped assemblies 22 and 24.

For tensioning the yarn 12 during knotting operation, a driven tensioning mechanism 36 is provided. In an illustrative example, the tensioning mechanism 36 includes a bracket 38 that is rotatably attached to the casing and to a hook 40 that is rotatably mounted to the bracket 38. In during knotting operation, the bracket 38 of the tensioning mechanism 36 can be brought so that it lowers into the space between the nodes 22 and 24 in the form of rings, after which the hook 40 can be driven so that it rotates and clung to the thread 12, when this thread 12 is stretched between the nodes 22 and 24 in the form of rings. Alternatively, the tensioning mechanism 36 may be driven so that it is lowered into the space between the nodes 22 and 24 in the form of rings, and the hook may be driven so that it rotates with the thread 12, which in this case is passed through the hook. After the yarn 12 is hooked by any of these methods, the bracket 38 can be raised by lifting it to thereby tension the yarn 12. While continuing the knotting operation, the spring, the induced motor torque, and the like, associated with the tension by the mechanism 36, they work so that they retain the tension of the yarn 12. After the knotting operation is completed, the bracket 38 can be retracted into the space between the nodes 22 and 24 in the form of rings (if necessary), and the hook 40 can be rotated, whereby you vobozhdayut thread 12 of the tensioning mechanism 36, or it is disengaged from this tensioning mechanism 36.

It is also understood that the tension mechanism can be tangentially moved to ring-shaped nodes 22 and 24 to provide tension to the yarn 12. In preferred embodiments, the tension this device applies to the yarn used to bundle wires into a bundle can be set by the user.

Like the tensioning mechanism, the loop forming hook assembly 26 comprises at least one hook 42 which is inserted into the space between the ring shaped assemblies 22 and 24 and removed from it for engagement and release / uncoupling of the yarn 12 as necessary to create space in which can go through the shuttle assembly 20 transporting the yarn 12 to thereby create the desired assembly. In addition, it may be desirable for the loop-forming hook assembly 26 to be movable in a tangential direction with respect to the ring-shaped assemblies 22 and 24. For this, the hook 42 can be attached to the slave assembly of the rack and pinion transmission mechanism, as, in particular, shown in FIG. 6A and FIG. 6B. The hook 42 can also be rotated to further engage and release / unhook the yarn 12.

A trimming mechanism 44 is provided for trimming the yarn 12 after the knot 10 is knotted around the product 14. Just as an example, the trimming mechanism 44 includes a fixed blade and a movable blade, between which the yarn 12 is located. For trimming the yarn 12 in this way movable the blade is driven by moving it relative to the fixed blade, after which the two blades clamp the thread 12. In the exemplary trimming mechanism shown in FIG. 9, the movable blade is driven using a rack and pinion gear assembly. It is clear that other nodes / mechanisms can be used to move the movable blade and / or to trim the thread 12 without any restrictions.

A feed assembly 46 is provided for supplying the yarn 12 to the shuttle assembly 20, after which the mechanism associated with the shuttle assembly operates to catch the filament 12. In the exemplary embodiment, the feed assembly 46 comprises a pair of driven rollers. It is understood that other mechanisms capable of performing this function may also be used.

As indicated above, in another embodiment of the knitting device 10, a cartridge 18 may be used as the source of knitting yarn, comprising a closed casing and an opening through which the yarn should be stretched. In this regard, the cartridge 18 can be inserted into the knitting device 10 with the possibility of its removal, being attached to the casing of the device, for example, on a snap fit, on a sliding fit, mounted on a pin or the like, and, if desired, may contain lengths of thread 12 of a given length. In one embodiment, the lengths of thread of a given length can be freely connected to each other so that after the first length of thread is pulled into the knotter 10 and used to tie the knot, the additional lengths of thread are continuously pulled into the knotter 10, i.e. , they follow the previously elongated stretch of thread until the feed ends of the strand are finished. Such free joining of the ends of the yarn segments can be achieved by using adhesives, applying notches along the entire length of the yarn, creating a perforated filler end between the yarn segments, and the like, but these examples are not limiting. In this embodiment, the lengths of thread can be placed inside the cartridge in a fan or multilayer configuration, for example, as shown in FIG. 11. Although this is not a prerequisite, a spring mechanism or the like may be provided for shifting the lengths of thread to the bottom of the cartridge in which the hole is located from which the lengths of thread are pulled, as shown in the example shown. It is desirable that such cartridges 18 are refillable. It is also understood that such lengths of thread can be wound on spool 16.

In yet another embodiment, the lengths of thread are pre-cut (they may include refueling ends) and are intended to be removed from the cartridge 18 one at a time.

A loading device 50 is provided for moving the lengths of thread from the cartridge 18 to the shuttle assembly 20, for example, the first length of the thread in the case of loosely coupled lengths of thread or each length of thread in the case of pre-cut lengths of thread. In the shown example, the loading device 50 includes a slave member 52, which is adapted to capture the end of an open section of thread, which can be accessed through an opening 54 in the cartridge 18, after which the slave element 52 is actuated to transport the captured section of thread to the shuttle assembly 20 for his selection of them. For this, the driven element 52 can be moved by the rack and pinion mechanism assembly, as shown in the drawing. However, it is understood that other mechanisms can be used to move the driven member 52 from the cartridge 18 to the shuttle assembly 20 without any limitation.

In addition to this, it is understood that if the thread 12 has pre-cut or loosely connected to each other segments, then the presence of a trimming mechanism may not be required.

Turning to the drawing of FIG. 17, it shows another knitting device, which is given as an example. In general, the device 10 'of FIG. 17 contains a shuttle 2600 transporting the thread, while causing it to move in a circular path around the bundle 2602 wires, and at least one device 2604 (two of which are shown in the drawing) for pulling the thread from the bundle 2602 wires at suitable times time during knotting operations with the possibility of its release and to rotate the threads to form loops through which shuttle 2600 passes during knotting operations. During the knotting operation, the shuttle 2600 moves along a circular path in one plane, which is usually a transverse bundle of wires. The thread is served in the shuttle 2600 device 2606 filing thread.

To move the shuttle 2600 in any direction along a circular path, the shuttle 2600 is provided with a gear outer surface adapted to be driven by respective driving gears 2608, as further shown in FIG. 18 and FIG. 19. Since the driving gears 2608 cause the shuttle 2600 to move, the shuttle is additionally supported by the rollers 2610. It will be appreciated that the number of driving gears 2608 and the rollers 2610 may be different as necessary depending, for example, on the size of the shuttle 2600.

In order to drive the drive gears 2608 and thereby cause the shuttle 2600 to move in a circular path, the drive gears 2608 can be mounted on the swing plate 2612, as shown in FIG. 20. The driven gear 2616 causes the swinging plate 2612 to swing, and the swinging movement of the swinging plate 2612 is transmitted to the driving gears 2608 through the eccentric pin 2614 and the output shaft 2615. In particular, the swinging of the swinging plate 2612 causes the eccentric pin 2614 to rotate, and similarly rotates the output shaft 2615 connected to it, driving the drive gear 2608 connected to it. The driven gear 2616 may be driven by a chain, belt, gear, or the like, connected to the engine. Alternatively, the rotation of the driving gears 2608 may be caused by direct connection to the engine without using the described swing plate mechanism, driven, for example, by a chain, belt, gear, or the like.

In order to tie a knot around the bundle 2602 of wires, the shuttle 2600 is moved over the hook 2618 or hooks of the device 2604, after which the device 2604 (and hook 2618) is pulled back, that is, moved away from the bundle 2602 of wires, whereby a loop is formed as shown in FIG. For this, the device 2604 is mounted on a support 2620, which is arranged to move laterally relative to the bundle 2602 of wires and rotate. As further shown in FIG. 21A - FIG. 21D, the support 2620 is separately rotated to thereby orient the loop at an angle with respect to the circular path along which the shuttle 2600 moves, thereby ensuring that the shuttle 2600 can pass through the loop and, accordingly, under the thread held by the hook 2618. Support 2620 can be rotated both in a clockwise direction and in a counterclockwise direction relative to the created loops through which the shuttle 2600 can pass when moving, respectively, in a clockwise direction and is directed ie counterclockwise. After the shuttle 2600 has been moved through the loop, the hook 2618 can be moved to release the thread, after which the thread can be tightened around the bundle 2602 wires, for example, by further moving the shuttle 2600. To ensure the movement of the hook 2618, the hook 2618 is installed with the possibility of rotation on the casing 2622, the bearing element for which is a support 2620, inside which is located a device that provides reciprocating motion, which is used to pull or push the hook 2618 relative to the casing 2622 for th to thereby move the hook 2618 between the position of the yarn engaging position and release the yarn as shown respectively in FIGS. 22A and FIG. 22B.

To further control the position of the thread during knotting, the system 2606 used to feed the thread to the shuttle 2600 is also rotatable in a plane typically transverse to the circular path of the shuttle 2600. In particular, as shown in FIG. 23A and FIG. 23B, the system 2606 can rotate in a first direction, for example, to the right, as shown in FIG. 23A, thereby causing the filament to approach the right side of the space in which the assembly is formed, and the system 2606 can rotate in a second direction, for example, to the left, as shown in FIG. 23B, thereby causing the filament to be supplied to the left side of the space in which the assembly is formed. Furthermore, as shown in FIG. 24, a locating pin 2626 may be provided for engaging with the formed assembly when tightening the thread, thereby preventing the assembly from being moved from the place where the assembly is tied, for example, when moving the shuttle 2600 to tighten the thread around the bundle 2602 of wires. Preferably, the locating pin 2626 is located on the movable device so that the pin 2626 can be retracted or otherwise disengaged from the thread during those times when the device is used to form the assembly or otherwise wrap the bundle of wires 2602. Preferably, the mounting pin 2626 is further configured to apply force to the assembly in a direction generally tangential to the bundle of wires 2602 at the location of the assembly.

The device 10 'is provided with an opening for inserting a bundle of wires 2602 into the device 10' and for removing the bundle 2602 of wires from the device 10 '. To facilitate the movement of the shuttle 2600 in a circular path during knotting, this opening is preferably closed (fully or partially) by a movable shutter 2628, as shown in FIG. 25A and FIG. 25B. Therefore, the movable shutter 2628 may further include driving gears 2630 and a support member 2632 (which may be rollers, a surface, etc.) for moving the shuttle 2600 through the movable shutter 2628 and to support it. In a preferred embodiment, the movable flap 2628 has a built-in drive chain for driving the movement of the driving gears 2630, and this drive circuit can be connected to the same devices that operate to drive the driven gears 2616. It is understood that additional could be provided a drive mechanism for moving the movable shutter 2628 to a predetermined position relative to and out of the opening of the device 10 '. In yet another embodiment shown in FIG. 26, there is no need for a movable shutter 2628, since the shuttle 2600 is so large that it overlaps the gap created by the opening of the device 10 '. In particular, in this embodiment, the shuttle 2600 is so long that when the shuttle 2600 overlaps the gap created by the opening of the device 10 ', then the shuttle 2600 engages with at least one of the driving gears 2608.

To hold the bundle of wires 2602 in the proper position when inserted into the device 10 ', the device 10' may further include a bundle capture device 2630. The beam capture device 2630 includes a retractable bracket 2632 that has a beam engagement portion 2634 located at one end thereof. The retractable bracket 2632 can be driven, for example, by an engine 2636 having an output shaft comprising a worm gear 2638, which in turn drives a gear mechanism 2640 that engages with corresponding teeth formed on the retractable bracket 2632. Thus, the retractable bracket 2632 and, accordingly, the beam engaging portion 2634, can be brought to or removed from the wire bundle 2602 by correspondingly rotating the worm gear 2638 connected to the output shaft of the motor 2636 in the direction both clockwise and counterclockwise. The retractable bracket 2632 is preferably made in an arcuate shape, and as a result moves in an arc, as shown in FIG. 27A and FIG. 27B, whereby for enabling and capturing bundles 2602 of wires of various sizes with the bundle engaging portion 2634 relative to the rear wall 2642 of the housing, which also has an arcuate shape, near the device 2604, that is, in the place near it where the assembly is to be formed . Since the device 10 'can accommodate bundles of wires 2602 of various sizes, the device 10' can be equipped with another device whose function is to stop the rotation of the motor 2636 (or to allow the bracket 2632 to slip against the driving force of the motor 2636) when the retractable bracket 2632 reliably presses a bundle of 2602 wires to the rear wall 2642.

For a more accurate filing of the thread to the shuttle 2600, the feeder 2606 is made retractable in the shuttle 2600 and retracted from it.
