Description

Technical Field

[0001] The present invention relates to the field of textile technology, in particular to an automatic wire and film winding device for a hollow tube and an automatic wire and film winding method thereof. Background Art

[0002] Existing automatic winding devices on the market can only perform simple winding operations. The stators of motors and generators used in daily life require winding operations. Currently available winding devices can automatically wind wire around the stators to form coils, achieving high production efficiency. Traditionally, manual winding around the cores can be difficult due to uneven force, causing the wire to become soft and untightened, leading to kinks and deformation, which can affect winding efficiency.

[0003] The other type of automatic winding device is mainly used in the textile field. The automatic winding device includes a speed regulating device, a shock absorbing device and an electronic weighing machine. The speed regulating device can adjust the speed of winding, and the shock absorbing device can reduce vibration and noise. However, the technology for automatic winding of protective film has not yet appeared. The existing automatic textile winding machines on the market cannot achieve winding of protective film while winding the wire. Before winding, it is generally necessary to manually stick the head end of the silk thread to the surface of the winding drum. The operation is not convenient enough, the production efficiency is low, and it cannot be guaranteed that the silk thread can be evenly wound on the surface of the winding drum during the winding process. The product quality pass rate is low.

[0004] In addition, there are four core processes in the production of textile rubber rings: inner and outer rubber sleeves around hollow circular tubes, outer rubber sleeves, winding, and protective film wrapping. The traditional winding and film wrapping process involves manually wrapping the yarn around the hollow tube in circles, and then wrapping the protective film around the tube in circles. This solution not only wastes a lot of manpower but also leads to low production efficiency. During manual winding and film wrapping, the hollow tube often falls over, causing the yarn and protective film wrapped around the hollow tube to misalign, requiring rewinding and film wrapping, which is very cumbersome.

[0005] It should be noted that the information disclosed in this background technology section is only intended to increase understanding of the overall background of the invention and should not be regarded as an admission or any form of implication that the information constitutes prior art already known to a person skilled in the art.

[0052] Example

[0053] Combine Figures 1 to 10 , this embodiment provides an automatic wire winding and film winding equipment for hollow tubes, comprising: a support frame 1, a material frame 2 and an operating frame 3. The support frame 1 includes a workbench 11 suitable for vertical placement of the hollow tube A. An axially rotatable limit seat 12 is provided on the workbench 11, and the limit seat 12 can vertically limit the hollow tube A on the workbench 11 in a quick-install manner, so that the hollow tube A can perform synchronous axial rotation following the limit seat 12. The material frame 2 is equipped with a wire outlet tower 21 and a film outlet disk 22. The opposite sides of the material frame 2 are respectively provided with a wire guide mechanism 23 for the output of the wire outlet tower 21, and a film guide mechanism 24 for the output of the film outlet disk 22. The operating frame 3 is equipped with a lifting module 31. The lifting module 31 can slide freely in the vertical direction. It is equipped with a wire clamping mechanism 32 and a clamping module. The wire feeding path of the wire clamping mechanism 32 is equipped with a wire guide mechanism 34 for inputting wire material, and the film feeding path of the film clamping mechanism 33 is equipped with a film guide mechanism 35 for inputting film material. The wire material is transferred from the wire outlet tower 21 along the wire guide mechanism 23 and the wire guide mechanism 34 to the wire clamping mechanism 32. The wire clamping mechanism 32 winds the wire material around the hollow tube A and, in cooperation with the lifting module 31 and the limit seat 12, performs the winding operation on the hollow tube. In addition, the film material is transferred from the film outlet disk 22 along the film guide mechanism 24 and the film guide mechanism 35 to the film clamping mechanism 33. The film clamping mechanism 33 winds the film material around the hollow tube A and, in cooperation with the lifting module 31 and the limit seat 12, performs the winding operation on the hollow tube A. The wire winding operation precedes the film winding operation, and the film winding operation follows immediately after the wire winding operation. The automatic wire and film winding equipment further includes a mounting frame 4. Mounting frame 4 is provided with a coupling mechanism 41 adapted for the hollow tube A. The coupling mechanism 41 has a first position away from the top of the hollow tube A and a second position close to and pressed against the top of the hollow tube A. When in the second position, the coupling mechanism 41 can stably secure the hollow tube A on the workbench 11 and allow the hollow tube A to rotate relative to the coupling mechanism 41.

[0054] In the above, the winding and film winding operations of the hollow tube are achieved through an automated mechanical method. When the wire outlet tower 21 outputs the wire material and the film outlet disk 22 outputs the film material, the wire guide mechanism 23 and the wire guide mechanism 34 are used to limit and tighten the yarn to prevent the yarn from loosening. The film guide mechanism 24 and the film guide mechanism 35 are used to limit and tighten the protective film so that the yarn will not loosen when it is pulled to the wire clamping mechanism 32 and the protective film will be pulled to the film clamping mechanism 33. The yarn and protective film are automatically wound on the hollow tube by the wire clamping mechanism 32 and the film clamping mechanism 33, eliminating the need for manual winding and film winding, saving a lot of time and increasing work efficiency. In particular, after the coupling mechanism 41 configured on the mounting frame 4 switches to the second position, the hollow tube configured on the limit seat 12 is further stably confined on the workbench 11, allowing the hollow tube to rotate relative to the workbench 11 to cooperate with the winding operation of the wire clamping mechanism 32 and the film clamping mechanism 33, significantly improving the operating performance of the entire machine.

[0055] like Figures 2 to 4 As shown, in one embodiment, the coupling mechanism 41 includes a slide 411 that is in vertical sliding contact with the mounting frame 4, a telescopic member 412 disposed on the slide 411, and a blind head member 413 disposed at the output end of the telescopic member 412. The telescopic member 412 is arranged in the transverse direction to drive the blind head member 413 to be engaged with the top of the hollow tube. The automatic wire winding and film winding equipment also includes an extension plate 42 that is slidably disposed on the other side of the mounting frame 4 and a pin member 43 disposed at the end of the extension plate 42, and the pin member 43 is directly opposite to the upper position of the limit seat 12. The extension plate 42 drives the pin member 43 in a flippable manner to be pressed onto the blind head member 413 located at the top of the hollow tube after the position is adjusted. In this embodiment, the extension plate 42 is specifically disposed on the slide on the other side of the mounting frame 4. The extension plate 42 and the slide are hingedly connected, allowing it to tilt upward by 30° to 45°. This facilitates further limiting the axial movement of the hollow tube via the ejector pin 43 after the bulkhead 413 is docked on the top of the hollow tube. Thus, the flip-type ejector pin 43 on the extension plate 42 uses the principle of leverage to increase the stability of the hollow tube during rotation.

[0056] like Figure 3As shown, in one embodiment, the upper side of the limit seat 12 is constructed as a latch head 121, and the latch head 121 is provided with a plurality of L-shaped spring pieces 122 for elastically engaging the bottom of the hollow tube, and the L-shaped spring pieces 122 arranged around the latch head 121 are axially arranged on the latch head 121 through an elastic member 123. The lower side of the limit seat 12 is connected to the external drive source 13. The latch head 121 is plugged and adapted to the bottom of the hollow tube, and the hollow tube is tightly placed on the workbench 11 by elastic engagement, which serves the purpose of quick release and elastic protection. Obviously, the external drive source 13 can be a motor external transmission mechanism connected to the limit seat 12, so as to realize the transmission of power to the limit seat 12 and thereby drive the hollow tube to rotate around its axis.

[0057] like Figures 5 to 10 As shown, in one embodiment, the material rack 2 includes a bottom plate 2A and a middle frame 2B that divides the bottom plate 2A into different working areas. The front side of the bottom plate 2A is configured as a working area suitable for the film discharge tray 22, and the rear side is configured as a working area suitable for the discharge tower 21. In this embodiment, the support frame 1 and the mounting frame 4 are adjacent to each other side by side, the operating frame 3 is compactly arranged behind the support frame 1, and the material rack 2 is compactly arranged behind the mounting frame 4.

[0058] Among them, such as Figure 5 As shown, the wire mechanism 23 includes a first tensioner 231 arranged on one side of the top of the middle frame 2B, and a plurality of guide wheels 232. The guide wheels 232 are arranged side by side, and a wire guide 232 is provided below one of the guide wheels 232. The wire guide 232 is arranged on the bottom plate 2A and is arranged adjacent to the outlet tower 21. Preferably, the wire guide 232 is configured as a guide wheel structure provided between two vertical brackets, which serves the purpose of threading the wire. In particular, the wire material enters the wire guide 232 through one of the guide wheels 232, and then passes through the wire guide 232 to another guide wheel 232, lengthening the wire transmission path and forming a U-shaped route.

[0059] As well as Figure 9 As shown, the wire guiding mechanism 34 comprises a first retaining ring 341, a wire guide pulley 342, a second tensioner 343, and a second retaining ring 344, which are mounted on the slide of the lifting module 31. The lifting module 31 is preferably a linear module. The wire guiding mechanism 34 is mounted on a horizontal plate of the slide. The first retaining ring 341 engages the wire material on the guide pulley 232 at the outlet end, while the second retaining ring 344 is retractable to guide the wire material into the wire clamping mechanism 32.

[0060] Furthermore, the wire clamping mechanism 32 includes a winding platform 321 and a wire clamping finger 322 disposed at an outer end of the winding platform 321. The wire clamping finger 322 is used as a pneumatic clamp to clamp the end of the wire material. The winding platform 321 can be freely and movably disposed on the slide and drives the wire clamping finger 322 to rotate about its axis to implement wire winding on the hollow tube. In this embodiment, the winding platform 321 can be freely further adjusted on the lifting module 31 under the configuration of the telescopic structure and the lifting structure. It also has a central power source to drive the wire clamping finger 322 at the outer end to move in an outer circle around its center line. This facilitates the wire clamping finger 322 to avoid each other with the mounting frame 4 and its associated coupling mechanism 41 during the winding process, thereby achieving a fast, effective and flexible winding operation.

[0061] Among them, such as Figure 6 As shown, the film guide mechanism 24 includes a plurality of roller members 241 arranged in sequence at intervals on the other side of the top of the middle frame 2B, and a film guide member 242 configured at the front end of the film discharge path of the film discharge tray 22. A sliding member 243 is provided on the film guide member 242. The film material descends along the roller members 241 and is then introduced into the film guide member 242. The sliding member 243 slides vertically to adjust the position of the film material so as to adaptively connect the end of the film material to the film guide mechanism 35. Therefore, the sliding member 243 is used to adjust and control the descending height of the film material on the sliding member 243, playing a more controllable tensioning and guiding role.

[0062] As well as Figure 10 As shown, the film guiding mechanism 35 includes a film turning assembly 351 and a film transport assembly 352, which are arranged on another horizontal plate of the slide of the lifting module 31. The film turning assembly 351 is sequentially provided with multiple rollers arranged in the horizontal, oblique, and longitudinal directions along the film material transmission direction. The film transport assembly 352 is provided with a driving shaft and a driven shaft. The driving shaft is externally powered to drive the turned film material along a preset direction and input it into the film clamping mechanism 33. Specifically, the turning mold assembly is arranged at the front end side of the entire film guiding mechanism 35, closer to the film guiding mechanism 24, and the turning mold assembly is sequentially provided with a horizontally extending roller shaft, an obliquely extending roller shaft, and a longitudinally extending roller shaft, so as to further turn the film material entering therein to provide a suitable posture for film winding preparation. Among them, the film material output by the film output tray 22 is in a horizontal direction, while the film material entering the film clamping mechanism 33 is in a vertical direction for grabbing and film winding operations. In addition, the film transport assembly 352 has its own power source, which drives the film material to be actively transported by rotation, thereby improving the maneuverability of the film material in the transport path and improving the film winding efficiency.

[0063] Furthermore, the film clamping mechanism 33 includes a film winding platform 331 and a film clamping finger 332 disposed at one outer end of the film winding platform 331. The film clamping finger 332 acts as a pneumatic gripper to grip the end of the film. The film winding platform 331 is movably mounted on a slide, driving the film clamping finger 332 to rotate about its axis to wrap the film around the hollow tube. The film winding platform 331 is structurally and functionally identical to the winding platform 321 and will not be further described here.

[0064] In the above description, the film clamping mechanism 33, film guiding mechanism 35, wire clamping mechanism 32, and wire guiding mechanism 34 are arranged in layers at different heights along the vertical direction of the slide of the lifting module 31. During the winding process, each mechanism is independent of each other and does not interfere with each other.

[0065] It should be understood that, in one embodiment, the workbench 11 is provided with a cutter mechanism 14 for wire and film materials at one end away from the limit seat 12. And, the automatic wire and film winding equipment also includes a glue dispensing mechanism (not shown) for performing a glue dispensing operation on the cut film material. Among them, the cutter mechanism 14 can perform automatic telescopic movement, and then cut the wire and film material wound on the bottom of the hollow tube. In particular, after the film material is cut, the end of the wound film material needs to be further tightly fitted to the hollow tube through the glue dispensing mechanism on the hollow tube to prevent the film material from loosening, moving out of position, etc. Whether to perform glue dispensing on the end of the wire material depends on the situation. It should be noted that the glue dispensing mechanism is a prior art and is not subject to excessive restrictions here.

[0066] In one embodiment, the wire clamping finger 322 can be independently raised and lowered on the winding platform 321 to which it belongs, so that the wire clamping finger 322 can be raised to avoid the movement after the first winding of the wire around the top of the hollow tube, and can be lowered and reset to the initial winding position after the wire is wound again for more than half a circle. In addition, the film clamping finger 332 can be independently raised and lowered on the film winding platform 331 to which it belongs, so that the film clamping finger 332 can be raised to avoid the movement after the first winding of the wire around the top of the hollow tube, and can be lowered and reset to the initial winding position after the film is wound again for more than half a circle. In this embodiment, the wire clamping finger 322 is docked to the bottom of the winding platform 321 by a vertically arranged telescopic member (not shown), so that the independent raising and lowering movement of the wire clamping finger 322 is controlled by the telescopic member. Specifically, in order to allow the wire to be wound around the top of the hollow tube, the wire clamping finger 322 can be released during the winding process (and the wire clamping finger 322 can be used to clamp the wire after the winding is completed), so that the wire wound around the hollow tube is continuously wound around the outer surface of the hollow tube under the downward movement of the lifting module 31 and the rotation of the limit seat 12, so that the wire needs to be initially wound and fixed on the hollow tube at the top of the hollow tube. Specifically, after the wire clamping finger 322 grabs the wire and winds it around the top of the hollow tube for one circle, the wire clamping finger 322 is moved upward to avoid the wound wire, and the wire is wound again for more than half a circle, and the wire clamping finger 322 is moved downward to its original position, so that the end of the wire is wound and bound to the hollow tube. At this time, the wire clamping finger 322 can be controlled to release the wire and further implement the winding operation. Similarly, it can be seen that the clamping finger 332 is also equipped with the telescopic parts mentioned above. Its specific implementation method can be referred to the above content and will not be repeated here.

[0067] In one embodiment, both the wire clamping finger 322 and the film clamping finger 332 are provided with a clearance space for the cutter mechanism 14 to extend into the fingertips to cut the end of the wire or film material after it is clamped. Obviously, after the winding or film winding is completed, in order to ensure that the hollow tube after subsequent loading can continue to be wound or film wound. In this embodiment, the winding process is completed after the wire or film is wound to the bottom of the hollow tube. At this time, the wire clamping finger 322 / film clamping finger 332 directly grasps the wire / film material again along the winding path / film winding path, and then the cutter mechanism 14 extends into the respective clearance spaces to cut the wire / film material, ensuring that the end of the wire / film material after cutting is still clamped by the wire clamping finger 322 / film clamping finger 332 for further winding or film winding.

[0068] Combine Figure 11 This embodiment further provides an automatic winding and film winding method for a hollow tube, which is applied to an automatic winding and film winding device to perform automatic winding and film winding operations on the hollow tube. The steps are as follows:

[0069] S1: Place the hollow tube on the workbench 11 and quickly release the bottom of the hollow tube using the limit seat 12 to synchronize the hollow tube with the limit seat 12. Then, switch the coupling mechanism 41 from the first position to the second position, thereby rotatably restraining the hollow tube on the workbench 11.

[0070] S2: Pull the wire material out of the wire outlet tower 21, pass through the wire guide mechanism 23 and the wire guide mechanism 34, and then be clamped in the wire clamping mechanism 32. Also, pull the film material out of the film outlet disc 22, pass through the film guide mechanism 24 and the film guide mechanism 35, and then be clamped in the film clamping mechanism 33.

[0071] S3: The wire is wound around the top of the hollow tube through the wire clamping mechanism 32, while the axial rotation of the hollow tube is controlled, and the lifting module 31 is driven to drive the wire clamping mechanism 32 to move downward, so that the wire material is continuously wound on the outer surface from the top to the bottom of the hollow tube.

[0072] S4: After the winding operation is completed, the film clamping mechanism 33 is controlled to wind the film on the top of the hollow tube, and the lifting module 31 is driven to drive the film clamping mechanism 33 to move downward, so that the film material is continuously wound on the outer surface from the top to the bottom of the hollow tube.

[0073] S5: After the film winding operation is completed, the joining mechanism 41 is switched to the first position to release the pressure limit on the top of the hollow tube. The hollow tube after winding is quickly removed from the limiting seat 12 of the workbench 11 and transferred to the next process. Steps S1 to S4 are continuously performed.

[0074] In the above, after step S3, the process further includes: cutting the wire material wrapped around the bottom of the hollow tube using the cutter mechanism 14. After step S4, the process further includes: cutting the film material wrapped around the bottom of the hollow tube using the cutter mechanism 14. Furthermore, a glue dispensing operation is further performed on the end of the film material to complete the automatic wire and film winding process.

[0075] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
