Description

Technical Field

[0001] The invention relates to the field of conveying and processing filament materials, and in particular to a wire twisting and knotting device and a wire twisting and knotting method. Background Art

[0002] For various silk and wire products, it is often necessary to wind the silk and wire onto a winding reel to form the final product. The winding machine is a device used to wind the silk thread onto an I-shaped wheel (wire reel). After the silk thread on an I-shaped wheel is fully wound, the silk thread between the pay-off machine and the full-wire wheel will be cut or melted, and then the thread head on the full-wire wheel will be fixed to avoid the silk thread wound on the I-shaped wheel from loosening.

[0003] The existing winding machine twisting and knotting device, such as the invention patent with authorization announcement number CN110625624B, provides a wire end tightening simulation robot and its use method. After winding on the winding machine, the wire end grabbing device, the moving device and the guide fuse device are used to perform the wire end tightening and knotting work. Since the wire end will be tightened synchronously when tying the knot, it can ensure that the wire end is tied tightly and will not be untied during subsequent processing, handling, transportation, etc. However, the device must complete the knotting work on the winding machine, which will affect the subsequent working efficiency of the winding machine. Therefore, the utility model patent with authorization announcement number CN219771437U further provides an automatic wire twisting device. After the winding is completed, the auxiliary robot will synchronously fix the wire wheel and the wire end to the machine platform of the automatic wire twisting device, and the wire twisting and knotting operations of multiple wire wheels can be synchronously completed on multiple machines, thereby realizing the synchronous winding and knotting, and improving the use efficiency of the winding machine.

[0004] The above-mentioned winding machine's twisting and knotting devices have the same twisting and knotting method, which is to set a rotatable wire take-up rod on the outer periphery of the wire wheel. The wire take-up rod forms a coil between the wire head and the wire wheel by revolving along the wire wheel, and drives the wire between the coil and the wire head and the wire wheel into the wire twisting clamp to be fixed, and then twist the wire and knot it. This twisting operation has the following problems:

[0005] 1. If Figure 1As shown, in the above-mentioned wire twisting method, the coil and silk thread between the thread end and the wire wheel are inserted into the wire twisting clamp 409, and the wire twisting clamp 409 gathers and tightens the multiple silk threads from the outside and then twists the wire. However, in this method, before the wire twisting clamp 409 is retracted, the silk thread inserted into the wire twisting clamp 409 is in an open state. When the opening angle of the silk thread is too large, it cannot be effectively inserted into the wire twisting clamp 409. At the same time, when the wire twisting clamp 409 is closed, the silk thread is easy to loosen, especially when the product wire diameter is small, resulting in the silk thread cannot be clamped, the wire twisting fails, and the thread end cannot be positioned, which will also cause the full wire wheel to spread. In addition, it is necessary to limit the position of the coil and the silk thread inserted into the wire twisting clamp 409, otherwise it will also cause the wire twisting failure or interfere with the wire twisting clamp 409.

[0006] 2. When transferring the wire reel to the automatic wire twisting device, in order to avoid interfering with the operation of the winding machine, it is necessary to first fuse and separate the wire between the current full wire reel and the pay-off reel on the winding machine, and simultaneously fix the full wire reel and its separated wire ends to the automatic wire twisting device. In order to realize the subsequent wire picking and twisting processing, a section of wire should be left between the wire end and the wire reel. Therefore, after the wire twisting operation is completed, there will be excess wire ends at the knotted wire ends, affecting the appearance of the product. When the excess wire ends are long, the wire twisting operation is inconvenient, and during the rotation and twisting process, the longer wire ends interfere with other mechanisms on the machine.

[0007] 3. In order to ensure that the winding machine is compatible with the processing of wire and line products with various wire diameters, it is also necessary to measure the wire diameter of the product before the product is knotted, so as to help classify the processed products later. The above-mentioned equipment does not provide a mechanism and method for wire diameter measurement and product classification. Therefore, it cannot adapt to the processing of various types of products, or when different types of products need to be classified, a separate wire diameter measurement step is required, which leads to low work efficiency.

[0008] Therefore, in order to solve the above problems, the present invention provides a wire twisting and knotting device and a wire twisting and knotting method thereof.

[0017] Preferably, the fuse mechanism also includes a second positioning clamp arranged on both sides of the upper fuse and the lower fuse, the second positioning clamp includes a second positioning groove, the opening of the second positioning groove is V-shaped, and the working positions of the upper fuse and the lower fuse are at the same height as the second positioning groove.

[0018] Preferably, the waste wire box is located at the bottom of the moving path of the waste wire clamp, and the inner side wall of the waste wire box close to the waste wire clamp forms a guide surface, and the guide surface is an inclined surface or a curved surface.

[0019] Preferably, the wire twist clamp comprises two opening and closing clamps, and the wire twist clamp is driven by a first rotating motor to rotate along its axis, and the axis of the first rotating motor is perpendicular to the axis of the rotating shaft.

[0020] Preferably, the rotating shaft is driven by the second rotating motor to drive the wire wheel turntable to rotate, and a boss for positioning the wire wheel a is also provided on the top of the wire wheel turntable. The wire take-up turntable is connected to the rotating shaft through a bearing, and is driven by the third rotating motor to drive the wire take-up rod on the bracket to revolve along the wire wheel turntable.

[0021] The method for twisting and knotting a wire, using the twisting and knotting device as described above, comprises the following steps:

[0022] S1: placing the wire wheel a on the wire wheel turntable, and fixing the wire end of the wire wheel a on the wire separation mechanism outside the wire wheel a;

[0023] S2: The two thread take-up rods revolve around the outer periphery of the thread wheel a along the winding direction of the thread wheel a, and after contacting the thread b between the thread end and the thread wheel a for the first time, they drive the thread b to continue to revolve around it, and the thread wheel a adaptively releases the thread as it rotates with the thread take-up rods, forming a coil d wound around the outer periphery of the two thread take-up rods, and then the two thread take-up rods continue to revolve around the thread wheel a, and again drive the thread b to revolve around the thread wheel a, until the thread take-up rods rotate to their initial positions and stop, so that the thread b forms a V-shaped thread b1 and a thread b2, and at least the thread b1 and the coil d are wound between the two thread take-up rods;

[0024] S3: the wire twisting clamp extends between the two wire take-up rods and simultaneously clamps the wire b and the coil d wound between the two wire take-up rods, presses down the wire take-up rods, and separates the wire b and the coil d from the wire take-up rods;

[0027] S6: Rotate the wire twisting clamp to make the wire b and the coil d clamped by the wire twisting clamp rotate and tighten synchronously to complete the knotting.

[0028] Preferably, the step S4 further comprises: when the wire b1 pulled by the waste wire clamp is reset, the wire b1 synchronously enters the working position of the wire diameter measuring instrument and the fusing mechanism, and the wire diameter measurement and the wire fusing are synchronously performed.

[0029] The beneficial effects of the technical solution of the present invention are mainly reflected in:

[0030] 1. The thread taking-up operation is completed synchronously by two thread taking-up rods. When the thread taking-up rods return to the initial position, the wire twisting clamp extends between the two thread taking-up rods. Since the two thread taking-up rods first position the coils and silk threads wound outside them, the wire twisting clamp can stably clamp the coils and silk threads wound outside the two thread taking-up rods, ensuring that the thread ends are successfully positioned before the thread twisting and knotting operation, avoiding loose thread ends, thread twisting failure or the spool a spreading out, and can also adapt to products with different wire diameters. In addition, since the silk threads and coils are fixed by the wire twisting clamp extending between the two thread taking-up rods, there will be no interference between the wire twisting clamp and accessories such as the thread taking-up rods.

[0031] 2. After the wire twisting clamp clamps the wire and the coil, the excess waste wire between the wire end and the wire twisting clamp is separated by the fusing mechanism. Therefore, when twisting the wire, the excess waste wire will not interfere with the various mechanisms on the machine. In addition, after the product processing is completed, no excess wire ends will remain, which improves the processing accuracy of the product. At the same time, before fusing, the two ends of the wire are fixed by the wire twisting clamp and the waste wire clamp respectively, and after fusing, the excess waste wire is transported to the waste wire box through the waste wire clamp to ensure that the wire end is transferred and accurately positioned during the fusing process, will not loosen, and effectively collect the waste wire.

[0032] 3. It includes a wire diameter measuring mechanism, which can measure products with different wire diameters, so as to facilitate the subsequent classification of the knotted products, so that the wire twisting and knotting device can be applied to the processing of products of different sizes, while improving the processing efficiency of the overall process. In addition, the processing positions of the wire diameter measuring mechanism and the fuse mechanism are located on the same horizontal line. Therefore, when the waste wire clamp clamps the excess wire and resets it, the wire between the wire head and the wire wheel a automatically moves to the working position of the fuse mechanism and the wire diameter measuring structure, and the fusing of the wire and the measurement of the wire diameter are completed synchronously. There is no need to move the fuse mechanism and the wire diameter measuring mechanism separately, and there is no need for distributed operations, which further improves the processing efficiency.

The wheel rotating mechanism 2 includes a rotating shaft 201 rotatably provided on the machine 1, and the axis of the rotating shaft 201 is preferably perpendicular to the surface of the machine 1. A wheel turntable 202 for placing a wheel a is provided on the rotating shaft 201, and the wheel turntable 202 is driven by the rotating shaft 201 to rotate, thereby realizing line release. The thread taking-up mechanism 3 includes a thread taking-up turntable 301 provided at the bottom of the wheel turntable 202, and a bracket 302 extends radially from the outer periphery of the thread taking-up turntable 301, and two thread taking-up rods 303 are telescopically provided on the bracket 302 along the axis, and the two thread taking-up rods 303 are parallel to the rotating shaft 201, and revolve along the wheel turntable 202 from the initial position. The thread separation mechanism 5 is located at a set position outside the thread taking-up mechanism 3, wherein when the robot or manipulator places the wire wheel a separated from the winding machine's anti-wire reel by melting on the wire twisting and knotting device, the wire wheel a is fixed on the wire wheel rotating disk 202, and the thread end of the wire wheel a is fixed on the thread separation device, so that a section of silk thread b is formed between the thread end fixed by the thread separation device and the wire wheel a, and two thread taking-up rods 303 rotate between the thread separation device and the wire wheel rotating disk 202 to wind the silk thread between the wire wheel a and the thread end around the outside of the thread taking-up rods 303, which is convenient for subsequent wire twisting and knotting; the specific structure of the robot or manipulator can be any robot or manipulator structure that can simultaneously fix and convey the wire wheel a and the thread end, and preferably adopts the robot structure disclosed in the utility model patent with authorization announcement number CN219771437U, which will not be repeated here.

[0049] like Figure 9-12 As shown, after the thread wheel a and the thread end are fixed on the thread wheel rotating disk 202 and the thread separation mechanism 5 in sequence, the two thread take-up rods 303 located on the outside of the thread wheel a revolve along the thread wheel a in the winding direction of the thread wheel a, and after the two thread take-up rods 303 contact the silk thread b between the thread end and the thread wheel a for the first time, they drive the silk thread b to continue to revolve, and the thread wheel a rotates with the thread take-up rods 303 to adaptively release the thread, forming a coil d wound around the outer periphery of the two thread take-up rods 303, and then the two thread take-up rods 303 continue to revolve around the thread wheel a, and again pull the silk thread b to revolve around the thread wheel a together, until the thread take-up rods 303 rotate to their initial position and stop, so that the silk thread b forms a V-shaped silk thread b1 and silk thread b2, and at least the silk thread b1 and the coil d are wound between the two thread take-up rods 303; during the whole process, the thread wheel a revolves with the thread wheel rotating disk 202 to cooperate with the operation of the thread take-up rods 303.

[0050] like Figure 4 , Figure 5 As shown, the thread twisting mechanism 4 includes a thread twisting clamp 401 that can be opened and closed. The thread twisting clamp 401 can rotate along its axis. When the thread take-up rod 303 is in the initial position, the thread twisting clamp 401 can reciprocate along the y-axis direction and then extend into or withdraw from between the two thread take-up rods 303. Figure 5 , Fig.12 As shown, the wire twisting mechanism 4 is used to tighten the wire wrapped between the two wire take-up rods 303 and twist the wire by rotation to achieve knotting; in actual operation, the wire twisting clamp 401 can simultaneously clamp the wires b1, b2 and the coil d wrapped between the two wire take-up rods 303. When the angle between b1 and b2 is too large, the wire twisting clamp 401 can only clamp the wire b1 and the coil d wrapped between the two wire take-up rods 303, and then press down the wire take-up rod 303 to separate the wire b and the coil d from the wire take-up rod 303, so as to facilitate the subsequent operation of the wire twisting clamp 401.

[0051] like Figure 2 , Figure 4 and Figure 6-Figure 8 As shown, the wire twisting and knotting device also includes a waste wire processing mechanism 6, which is arranged on one side of the wire twisting mechanism 4, preferably side by side on the side of the wire twisting mechanism 4 close to the wire separating mechanism 5 (hereinafter, the arrangement direction of the above-mentioned wire twisting mechanism 4, the waste wire processing mechanism 6 and the wire separating mechanism 5 is set as the x-axis direction, and the direction perpendicular to the upper surface of the machine 1 is set as the axial direction), including a waste wire clamp 601 and a waste wire box 602, the waste wire clamp 601 can reciprocate along the y-axis direction and the moving path of the waste wire clamp 601 passes through the wire separating mechanism 5 and the wire wheel rotating mechanism 2, and is used for clamping the wire b1 between the wire end on the wire separating mechanism 5 and the wire twisting clamp 401 after the wire twisting clamp 401 clamps the wire b and the coil d and before the waste wire is melted, and then reset, and move to the top of the waste wire box 602 after the waste wire is melted and separated, and transport it into the waste wire box 602.

The specific structure of the line-dividing mechanism can refer to the specific structure of the wire clamping head assembly in the utility model patent with authorization announcement number CN219771437U, which will not be repeated here.

[0053] like Figure 2-Figure 5As shown, the wire twisting and knotting device also includes a fuse mechanism 7 and a wire diameter measuring mechanism 8, which are arranged between the waste wire processing mechanism 6 and the wire twisting mechanism 4, and the working positions of the fuse mechanism 7 and the wire diameter measuring mechanism 8 are at the same height, and the fusing and wire diameter measurement of the wire b1 can be completed at the same time. In one embodiment, the fuse mechanism 7 and the wire diameter measuring mechanism 8 are arranged on the same mounting frame, and the mounting frame is driven by a cylinder or a motor to translate along the y-axis and / or z-axis direction. The translation of the mounting frame can be achieved by cooperating with guide mechanisms such as guide rails and moving modules. This is a prior art and will not be elaborated here. The synchronous adjustment of the working heights of the fuse mechanism 7 and the wire diameter measuring mechanism 8 is achieved. When the waste wire clamp 60 After the wire b1 is clamped and reset, since both ends of the wire b1 are fixed by the waste wire clamp 601 and the wire twisting clamp 401, it is only necessary to adjust the position of the mounting frame so that the wire b1 enters the working positions of the fuse mechanism 7 and the wire diameter measuring mechanism 8, and the fusing and wire diameter measurement of the wire b1 can be completed synchronously; in a preferred embodiment, the working positions of the fuse mechanism 7 and the wire diameter measuring mechanism 8 as well as the wire twisting clamp 401 and the waste wire clamp 601 are located at the same height. When the waste wire clamp 601 clamps the wire b1 and resets it, the wire b1 automatically enters the working positions of the fuse mechanism 7 and the wire diameter measuring mechanism 8, and there is no need to adjust the positions of the fuse mechanism 7 and the wire diameter measuring mechanism 8, thereby maximizing the work efficiency and simplifying the configuration.

The elastic member 306 passes through the corresponding guide holes and is connected to the pull-down plate 307.

Specifically, the positioning block 308 is driven to lift by a cylinder. When the thread taking-up rod 303 needs to be lowered, the cylinder drives the positioning block 308 to press on the top of the pull-down plate 307 and continue to descend. The pull-down plate 307 descends, and at this time, the elastic member 306 is driven to be pulled down by the pull-down plate 307, and the two guide rods 305 are also driven to descend along the guide holes, and then the thread taking-up rod 303 on the top of the two guide rods 305 also descends accordingly; when the thread taking-up rod 303 needs to be reset, the positioning block 308 rises and leaves the pull-down plate 307, the pressure disappears, and the elastic member 306 drives the guide rod 305 and the thread taking-up rod 303 to automatically reset.

In a preferred embodiment, the opening of the wire diameter measuring instrument 801 and the interior of the first positioning groove are also V-shaped, and the V-shaped angle inside the first positioning groove is smaller than the opening angle of its external opening, thereby guiding the wire b1 to enter the working position of the wire diameter measuring instrument 801.

[0057] In some embodiments, the fuse mechanism 7 includes an upper fuse 701 and a lower fuse 702 which are arranged relatively to each other. The upper fuse 701 and the lower fuse 702 can move relative to each other and open and close.

In some other embodiments, the waste wire box 602 can also be set on the outside of the workbench. The waste wire clamp 601 can be driven by a driving mechanism to flip to the top of the waste wire box 602, and then the waste wire is released and falls into the waste wire box 602. The driving mechanism can use a flipping motor or a cylinder, etc., which will not be repeated here.

[0060] like Figure 7 , Figure 8As shown, in some embodiments, the thread take-up turntable 301 is also arranged on the rotating shaft 201, and ensures that the thread take-up turntable 301 does not rotate with the rotating shaft 201.

A boss 203 for positioning the thread wheel a is also arranged on the top of the thread wheel turntable 202. The thread take-up turntable 301 is driven by the third rotating motor 10 to drive the thread take-up rod 303 on the bracket 302 to revolve along the thread wheel turntable 202. A transmission part is integrally provided at the bottom of the thread wheel turntable 202, and the motor shaft of the third rotating motor 10 is connected to the second transmission part 14 through a second belt 12.

In one embodiment, the connection structure between the line take-up turntable 301, the rotating shaft 201 and the line take-up turntable 301 can refer to the connection structure between the line wheel rotating mechanism 2 and the line take-up mechanism 3 in the utility model patent with authorization announcement number CN219771437U, which will not be repeated here.

[0061] The method for twisting and knotting a wire, using the twisting and knotting device as described above, comprises the following steps:

[0062] S1: Place the wire wheel a on the wire wheel turntable 202, and fix the thread end of the wire wheel a on the wire separation mechanism 5 outside the wire wheel a.

[0063] S2: Figure 9-11As shown, the two thread take-up rods 303 revolve around the periphery of the thread wheel a along the winding direction of the thread wheel a, and drive the thread b to continue to revolve after the first contact with the thread b between the thread end and the thread wheel a, and the thread wheel a adaptively releases the thread as it rotates with the thread take-up rod 303 to form a coil d wound around the periphery of the two thread take-up rods 303, and then the two thread take-up rods 303 continue to revolve around the thread wheel a, and again drive the thread b to revolve around the thread wheel a until the thread take-up rod 303 rotates to its initial position and stops, so that the thread b forms a V-shaped thread b1 and a thread b2, and at least the thread b1 and the coil d are wound between the two thread take-up rods 303. During the entire thread taking-up process, the thread wheel a rotates to release the thread to cooperate with the winding of the thread take-up rod 303.

[0064] S3: The wire twisting clamp 401 extends between the two thread take-up rods 303 and simultaneously clamps the wire b and the coil d wound between the two thread take-up rods 303 , presses down the thread take-up rods 303 , and separates the wire b and the coil d from the thread take-up rods 303 .

[0065] In some embodiments, the wire twisting clamp 401 can simultaneously clamp the wires b1, b2 and the coil d wound between the two wire take-up rods 303. Fig.12 As shown, when the angle between b1 and b2 is too large, the wire twisting clamp 401 can only clamp the wire b1 and the coil d wound between the two wire take-up rods 303 .

[0066] In one embodiment, a guide seat 304 is provided on the bracket 302 on one side of the thread take-up turntable 301, and a guide rod 305 is provided at the bottom of the two thread take-up rods 303, and the guide rods 305 can be floated on the guide seat 304, and an elastic member 306 is also provided between the two guide rods 305. The guide seat 304 is provided with a guide hole corresponding to each guide rod 305 and the elastic member 306, and the two guide rods 305 can float through the corresponding guide holes, and a pull-down plate 307 is provided at the bottom of the guide seat 304, and the elastic member 306 passes through the corresponding guide holes and is connected to the pull-down plate 307. A positioning pressure block 308 can also be lifted and lowered at the bottom of the thread twisting mechanism 4. When the thread take-up rod 303 is in the initial position, the positioning pressure block 308 is located on the top of the pull-down plate 307, and the positioning pressure block 308 can selectively contact the pull-down plate 307 by lifting and lowering. Specifically, the positioning pressure block 308 is driven to lift and lower by the cylinder. When the thread take-up rod 303 needs to be lowered, the cylinder drives the positioning pressure block 308 to press on the top of the pull-down plate 307 and continue to descend. The pull-down plate 307 descends, and at this time the elastic member 306 is driven to be pulled down by the pull-down plate 307, and the two guide rods 305 are also driven to descend along the guide holes, and then the thread take-up rod 303 on the top of the two guide rods 305 also descends accordingly. At this time, the silk thread b and the coil d are separated from the thread take-up rod 303, and then the wire twisting clamp 401 retracts and resets, which is convenient for the subsequent wire twisting operation of the wire twisting clamp 401; when the thread take-up rod 303 needs to be reset, the positioning pressure block 308 rises and leaves the pull-down plate 307, the pressure disappears, and the elastic member 306 drives the guide rod 305 and the thread take-up rod 303 to automatically reset.

[0067] S4: the waste wire clamp 601 clamps the wire b1 between the wire end and the wire twisting clamp 401, the wire separation mechanism 5 releases the wire end, and the wire b1 pulled by the waste wire clamp 601 is reset.

[0068] In a preferred embodiment, the step S4 also includes that when the wire b1 pulled by the waste wire clamp 601 is reset, the wire b1 synchronously enters the working position of the wire diameter measuring instrument 801 and the fuse mechanism 7. At this time, the working positions of the waste wire clamp 601, the wire twisting clamp 401, the wire diameter measuring instrument 801 and the fuse are at the same height, and the wire diameter measurement and wire fusing can be performed synchronously.

[0069] In one embodiment, before the wire b1 pulled by the waste wire clamp 601 is reset, the upper fuse 701 and the lower fuse 702 of the fuse mechanism 7 are opened, and when the wire b1 pulled by the waste wire clamp 601 is reset, the wire synchronously enters the wire diameter measuring instrument 801 and between the upper fuse 701 and the lower fuse 702. At this time, the upper fuse 701 and the lower fuse 702 are closed, and the wire diameter measurement and wire fusing are synchronously completed.

[0070] S5: After the fusing mechanism 7 fuses and separates the wires between the waste wire clamp 601 and the wire twisting clamp 401 , the waste wire clamp 601 transports the separated waste wires to the waste wire box 602 .

[0071] S6: Rotate the wire twisting clamp 401 to make the wire b and the coil d clamped by the wire twisting clamp 401 rotate and tighten synchronously to complete the knotting. The number of rotations of the wire twisting clamp 401 is not limited and can be adjusted according to actual needs.

[0072] There are many implementation methods of the present invention, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
