Description

Technical Field

[0001] This utility model belongs to the field of zipper head production technology, and specifically relates to a zipper head assembly machine with a rotating feeding device for the zipper tab. Background Technology

[0002] Zipper heads consist of the zipper pull and the pull tab that is movably connected to it. Traditionally, assembly is mostly done manually, relying on workers to assemble the components of the zipper head using appropriate tooling and fixtures, and then riveting them together. This method generally suffers from high labor intensity, low production efficiency, and high scrap rates, making it difficult to guarantee the quality of the zipper heads. Therefore, various mechanized zipper head assembly machines have become widespread. Among these, the conveyor mechanism used to transport the various components in the assembly machine is extremely important, directly affecting the stability of the assembly machine's operation and the product qualification rate.

[0003] Existing zipper head assembly machines typically have a circular turntable with a receiving seat for receiving zipper heads or zipper tabs. Around the turntable are zipper head conveying devices, zipper tab conveying devices, riveting devices, and discharge devices. During operation, zipper tabs are generally conveyed into the receiving seat via the zipper tab conveying device. Correspondingly, the receiving seat has slots for placing the zipper tabs. Existing zipper tab conveying devices mainly include a vibrating plate, a zipper tab track, and a push rod. The push rod is located at the end of the zipper tab track, and a cylinder drives the push rod to push the zipper tab from the track into the corresponding slot in the receiving seat. However, this existing zipper tab conveying device has a simple structure and the conveying process is not stable enough.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1 to 5 As shown, a zipper pull assembly machine includes a zipper pull hopper 21, a zipper pull guide rail 22 fixed at the outlet of the zipper pull hopper 21, and a rotating feeding mechanism fixed at the outlet of the zipper pull guide rail 22. The rotating feeding mechanism includes a rotary drive device 23 and a feeding seat 24 rotatably disposed at the output end of the rotary drive device 23. In this invention, the zipper pull hopper 21 is preferably a vibrating hopper conventional in the art. The end of the zipper pull guide rail 22 near the vibrating hopper is slightly higher than the other end. Under the action of vibration, the pull piece 20 is conveyed to the outlet of the pull piece guide rail 22. Then, by rotating the feeding mechanism, the pull piece 20 located at the outlet of the pull piece guide rail 22 is received and sent to the pull piece slot 10 of the receiving seat 1. Specifically, when the pull piece 20 is located in the pull piece guide rail 22, it is in a horizontal position. The loading seat 24 has a groove 240 for supporting the pull piece 20. The size of the groove 240 matches the size of the pull piece 20. When the loading seat 24 rotates to the outlet of the pull piece guide rail 22, it is in the receiving position (e.g., Figure 1 As shown), when the loading seat 24 is in the receiving position, the bottom of the inner side of the groove 240 is flush with the bottom of the outlet of the pull-piece guide rail 22. The pull-piece 20 enters the groove 240 under the vibration of the pull-piece hopper 21. This arrangement allows the groove 240 to receive the pull-piece 20 coming out of the outlet of the pull-piece guide rail 22. When the loading seat 24 rotates to the pull-piece slot 10, it is in the loading position (as shown). Figure 2As shown, the rotating feeding mechanism is also equipped with a pull piece pushing mechanism 25 for feeding the pull piece 20 in the groove 240 of the feeding seat 24 to the pull piece slot 10. When the feeding seat 24 is at the outlet of the pull piece guide rail 22 to receive the pull piece 20, the pull piece 20 is in a horizontal state. When the feeding seat 24 rotates to the feeding station, the pull piece 20 is in a vertically arranged state. The rotating drive device 23 controls the feeding seat 24 to reciprocate between the receiving station and the feeding station, continuously feeding the pull piece 20 that comes out of the pull piece guide rail 22 to the feeding station, and feeding the pull piece 20 into the pull piece slot 10 through the pull piece pushing mechanism 25. The rotating feeding mechanism of this utility model can rotate the horizontal pull piece 20 to a vertical state and then feed the pull piece 20 into the pull piece slot 10 through the pull piece pushing mechanism 25. The structure is stable and reliable.

[0039] Specifically, the rotating feeding mechanism is fixed to the outlet of the pull tab guide rail 22 via a fixed base 26. It should be noted that in actual use, the fixed base 26 is fixed to the frame of the zipper head assembly machine (e.g., Figure 4 As shown), the fixed base 26 includes a horizontally arranged horizontal plate 261 with a vertically arranged vertical plate 262 on the horizontal plate 261. A rotary drive device 23 is fixed on the horizontal plate 261, and a pull-piece pushing mechanism 25 is fixed on the vertical plate 262. The outlet of the pull-piece guide rail 22 is located on the side of the vertical plate 262 near the loading seat 24. The loading seat 24 rotates close to one side of the vertical plate 262. When the loading seat 24 is in the loading position, the pull-piece 20 is located in the groove 240, and the side of the vertical plate 262 near the groove is close to the groove 240. A baffle mechanism for blocking the outlet of the pull-piece guide rail 22 is also fixed on the horizontal plate 261. The baffle mechanism includes a baffle seat 27 and a retractable baffle plate 271 disposed in the baffle seat 27. The baffle plate 271 is vertically arranged and located on one side of the vertical plate 262, corresponding to the outlet of the pull-piece guide rail 22. The top of the material plate 271 is located at the receiving station. A retaining spring 272 is fixedly installed at the bottom of the retaining plate 271. One end of the retaining spring 272 is fixedly connected to the bottom of the retaining plate 271, and the other end is fixedly installed on the horizontal plate 261. The retaining seat 27 is used to fix the retaining plate 271. When the loading seat 24 is located at the loading station, the retaining plate 271 is located at the exit of the pull plate guide rail 22, blocking the pull plate 20 and preventing the pull plate 20 from falling out of the guide rail. When the sheet guide rail 22 falls, and the loading seat 24 rotates to the receiving position, the loading seat 24 presses the baffle plate 271 downward. The baffle plate 271 compresses the baffle spring 272 at its bottom and moves downward. When the loading seat 24 rotates to the loading position after receiving the sheet 20, the baffle plate 271 is reset under the action of the baffle spring 272. The baffle plate 271 extends again to the exit of the sheet guide rail 22 and blocks the sheet 20.

[0040] The feeding seat 24 of this utility model includes a feeding plate 241 rotatably connected to a rotary drive device 23 at one end and a supporting component fixed to the other end of the feeding plate 241. A groove 240 is provided on one end of the feeding plate 241 opposite to the supporting component. The groove opening of the groove 240 near the pull tab groove 10 is the feeding groove opening. The supporting component is used to support the feeding groove opening of the groove 240 to prevent the pull tab 20 from falling out of the feeding groove opening when the feeding seat 24 drives the pull tab 20 to the feeding station. Specifically, the supporting component includes a supporting seat 242 fixed to the feeding plate 241 and a supporting plate 243 fixed to the supporting seat 242. The supporting plate 243 is provided on the side of the supporting seat 242 away from the feeding plate 241. A supporting block 244 is retractably provided inside the supporting seat 242. Correspondingly, the supporting block 244 and the supporting plate 243 are connected to each other. A spring 245 is fixedly installed between the support and the feed trough. A block 244 extends from the support seat 242 to the feed trough opening and blocks the feed trough opening. A cylinder 246 is fixedly installed on the top of the block 244. A relief groove 247 is opened on the top of the support seat 242 corresponding to the position of the cylinder 246 to allow the cylinder 246 to move. The block 244 always blocks the feed trough opening under the action of the spring 245. When the feed seat 24 is in the receiving position, only one side of the groove 240 corresponding to the pull tab guide rail 22 is not blocked, so that the groove 240 can receive the pull tab 20 coming out from the outlet of the pull tab guide rail 22. When the feed seat 24 is in the feeding position, the side of the groove 240 corresponding to the pull tab guide rail 22 is blocked by the vertical plate 262. This setting allows the pull tab 20 to be wrapped around the inside of the groove 240, making it less likely to fall off.

[0041] The pull tab pushing mechanism 25 includes a pull tab pushing cylinder 251 fixed on the vertical plate 262 and a pusher seat 252 fixed on the output end of the pull tab pushing cylinder 251. The pusher seat 252 is at the same horizontal position as the pull tab groove 10. A pusher rod 253 is provided on the pusher seat 252 at the position corresponding to the pull tab groove 10. Correspondingly, a through hole is provided on the groove 240 at the position corresponding to the position of the pusher rod 253 for the pusher rod 253 to extend into. A pusher plate 254 is provided on the pusher seat 252 at the position corresponding to the position of the cylinder 246. A through groove 248 is provided on the abutment seat 242 at the position corresponding to the position of the pusher plate 254 for the pusher plate 254 to extend into. The through groove 248 is connected to the relief groove 247. The push rod 253 and the push plate 254 are arranged in parallel. The cylinder 246 is located on the moving path of the push plate 254. The end of the push plate 254 near the loading seat 24 is provided with a push slope 255 for pushing the cylinder 246 towards the top plate 243. The push slope 255 is set at the position of the cylinder 246 at the top of the top block 244. Furthermore, the push seat 252 is fixedly connected to the output end of the pull plate push cylinder 251 through a straight plate 250. The straight plate 250 is provided with a sensor 256 for sensing the moving distance of the output end of the pull plate push cylinder 251 to prevent the output end of the pull plate push cylinder 251 from moving too far and causing collision.

[0042] The working principle of the pull-tab rotating feeding device of this utility model is as follows:

[0043] When the pull-tab feeding mechanism 25 is not working, the abutment block 244, under the action of the abutment spring 245, always blocks the feeding slot of the groove 240. When it is necessary to feed the pull-tab 20 onto the receiving seat 1, the disc 20 drives the receiving seat 1 to rotate to the position of the pull-tab conveying device 2. Under the action of vibration, the pull-tab hopper 21 feeds the pull-tab 20 towards the outlet of the pull-tab guide rail 22. The rotary drive device 23 drives the feeding seat 24 to rotate to the receiving position to receive the pull-tab 20. The pull-tab 20 is located in the groove. The loading seat 24 behind the slot 240 drives the pull plate 20 to rotate to the loading position. The pull plate pushing mechanism 25 works, and the output end of the pull plate pushing cylinder 251 drives the pushing rod 253 and the top pushing plate 254 on the pushing seat 252 to move towards the position of the loading seat 24. This causes the top pushing plate 254 to touch the cylinder 246 in the through slot 248. Under the pushing action of the top pushing inclined surface 255, the cylinder 246 moves towards the top plate 243, causing the cylinder 246 to move in the relief slot 247. 246 drives the abutment block 244 to compress the abutment spring 245 and move towards the abutment plate 243, away from the feeding slot. This allows the push plate 254 to move towards the feeding seat 24, driving the cylinder 246 and the abutment block 244 away from the feeding slot. At this time, the push rod 253 extends into the through hole of the groove 240 and pushes the pull piece 20 in the groove 240 onto the pull piece slot 10. It should be noted that the lengths of the push plate 254 and the push rod 253, as well as the slope of the push slope 255, are... The device should be reasonably configured so that when the push plate 254 drives the abutment block 244 away from the feeding slot, the push rod 253 can just extend into the groove 240 to push out the pull piece 20. After being pushed out, the output end of the pull piece pushing cylinder 251 retracts, driving the push plate 254 away from the cylinder 246. The abutment block 244 retracts under the action of the abutment spring 245, blocking the feeding slot. It should be noted that the rotary drive device 23 in this utility model preferably adopts a conventional rotary motor in the art.

[0044] The present invention provides a pull sheet rotating feeding device that uses a rotating feeding mechanism to feed the pull sheet 20 from the outlet of the pull sheet guide rail 22 to the pull sheet slot 10, and uses a pull sheet pushing mechanism 25 to feed the pull sheet 20 into the pull sheet slot 10. Compared with the existing pull sheet conveying device, it has a reliable structure and a more stable conveying process.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
