Description

Technical Field

[0001] The invention belongs to the field of zipper machines, and relates to an upper stop oblique-mouth chain threading machine with upper stop detection. Technical Background

[0002] The chain belt with a beveled top stop can be formed into the top stop and the bottom stop at one time before the upper slider is installed, and then the slider is inserted through the beveled top stop to complete the upper slider work. This method of inserting the slider can reduce the process steps and reduce the length of the production line and has been widely promoted recently.

[0003] Chinese invention patent ZL2023114075604 discloses an upper stop oblique chain threading machine, which positions the chain belt to a set position through an upper stop positioning clamp, and then conveys the pull head to the set position through a pull head conveying mechanism, so that the chain inlet of the pull head is aligned with the oblique opening of the chain belt, and then the oblique opening is pushed into the chain inlet of the pull head through a side push block, and then the chain belt traction mechanism drives the chain belt to move to realize chain threading.

[0004] The upper stop positioning clamp of this chain threading method is provided with a chain belt slot at intervals between two clamping parts. The height of the chain belt slot is greater than the height of the chain belt cloth tape, but less than the height of the upper stop, so that the side of the positioning clamp is controlled to abut against the front end of the upper stop when the positioning clamp retreats, and the upper stop is retreated to the set position together, so as to realize the positioning of the upper stop. Since the height of the upper stop is the same as the height of the chain teeth, even if there is no upper stop, the positioning clamp will abut against the side of the chain teeth when retreating, and retreat with the chain teeth together, but due to the wrong position, the upper pull head cannot be effectively pulled up, which will damage the equipment. Therefore, this chain threading method cannot detect whether the upper stop on the chain belt has fallen off, but since the upper stop and the chain teeth only differ in width, and the size is small and the running speed is fast, the light detector cannot accurately detect whether the upper stop has fallen off. Summary of the invention

[0005] In view of the above problems, the present invention provides a top stop bevel chain threading machine with top stop detection, which has the advantage of being able to effectively detect whether there is a top stop on the chain belt, thereby avoiding damage caused by the equipment still running without a top stop.

[0008] The upper stop positioning mechanism also includes a slide rail arranged on the frame, the slide rail is parallel to the chain belt channel, a slider is slidably arranged on the slide rail, a slide seat is fixed on the slider, a telescopic cylinder is fixed on the slide seat, the output end of the telescopic cylinder is fixedly connected to the clamping cylinder, and the telescopic direction of the output end of the telescopic cylinder is perpendicular to the direction of the slide rail;

[0009] A tension spring is also connected between the slide and the frame, and the tension spring always gives the slide a force to move backward;

[0010] The frame is also provided with a position detection plate of an upper stop positioning mechanism;

[0011] The frame is also provided with a positioning cylinder for an upper stop positioning mechanism. When the detection board detects that the upper stop positioning clamp reaches the set position, the protruding end of the positioning cylinder is controlled to extend forward and press against the upper stop positioning mechanism to prevent the slide from retreating; if the detection board does not detect the signal that the upper stop positioning clamp reaches the set position within the set time, the control device stops operating.

[0012] The present invention is further configured as follows: a positioning seat is fixed on the slide seat, a positioning groove is formed on the positioning seat toward the rear, the positioning cylinder is arranged behind the positioning seat, the extended end of the positioning cylinder is arranged toward the positioning groove, and the extended end of the positioning cylinder is extended and abuts against the positioning groove to prevent the slide seat from retreating.

[0013] The present invention is further configured as follows: the extended end of the telescopic cylinder is connected to a first guide seat, a first guide rail matching the first guide seat is fixed on the slide seat, and the clamping cylinder is fixedly connected to the first guide seat via a fixing plate.

[0014] The present invention is further configured such that: the detection plate is arranged above the slide seat and detects the position of the slide seat.

[0015] The present invention is further configured as follows: the upper stop side push mechanism comprises a push block arranged behind the upper stop positioning clamp and a push block cylinder driving the push block to move left and right, and the push block cylinder is fixedly connected to the slide seat.

[0016] The present invention is further configured as follows: the extended end of the push block cylinder is connected to a second guide seat, a second guide rail matching the second guide seat is fixed on the slide seat, and the push block is fixedly connected to the second guide seat.

[0017] The present invention is further configured as follows: the push block comprises an upper stop groove and a cloth belt groove matching with the upper stop, and the side surface of the upper stop groove is a side push surface.

[0018] Through the above arrangement, the push block can push the upper stop more accurately, thereby improving the yield rate.

[0019] The present invention is further configured as follows: the block sensing mechanism includes a sensing strip, which is rotatably arranged on a frame, the lower end of the sensing strip is a sensing part, which is arranged on the block channel and the distance between the sensing part and the block channel is less than the block height, and a detection switch for detecting the position of the sensing strip is also provided on the frame.

[0020] The present invention is further configured as follows: the sensing pressure strip is "L"-shaped, comprising a hinge section and a sensing section, a hinge seat is fixed on the frame, a hinge groove is formed on the hinge seat, the hinge section is partially arranged in the hinge groove, a cover plate is fixed on the outside of the hinge groove, a pin shaft is fixed in the middle of the hinge seat, passing through the cover plate and the hinge section, so that the hinge section is rotatably connected in the hinge groove, and the lower part of the sensing section is the sensing part.

[0021] By arranging the hinge section in the hinge groove, it can be prevented that when the block passes the induction pressure strip quickly during high-speed operation of the equipment, the induction pressure strip is bounced too high and the equipment is damaged.

[0022] The present invention is further configured as follows: the rear of the sensing part is designed as an arc.

[0023] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: the present invention forms a sprocket channel on the upper stop positioning clamp, and the width of the sprocket is less than the width of the sprocket channel and less than the width of the upper stop. In the normal state of the chain belt with the upper stop, after the induction pressure strip detects the block, the upper stop positioning clamp extends and closes in the transition section without sprockets, and the chain belt traction device pulls the chain belt to continue to move forward. Since the width of the upper stop is greater than the width of the sprocket channel in the upper stop positioning clamp, and the positioning clamp is fixed on the slide seat, the front end of the upper stop moves forward together with the side surface of the upper stop positioning clamp until the detection plate detects the signal that the upper stop positioning mechanism reaches the set position, and then controls the positioning cylinder to extend and press against the upper stop positioning mechanism to prevent the slide seat from being pulled back by the tension spring, and then completes the subsequent upper pull head action;

[0024] If the top stop of the chain belt falls off, the sensing pressure strip detects the block, and the top stop positioning clamp extends out and closes in the transition section, and the chain belt continues to move forward. However, since there is no top stop and the sprocket channel on the positioning clamp is larger than the width of the sprocket, the sprocket on the chain belt passes directly through the sprocket channel and cannot move forward with the positioning clamp. Therefore, if the detection board does not detect that the top stop positioning mechanism is in place within the set time, it is determined that there is no top stop on the chain belt, and then the equipment is controlled to stop running to prevent equipment damage.

[0045] A tension spring 312 is also connected between the slide 307 and the frame, and the tension spring 312 always gives the slide 307 a force to move backward;

[0046] A detection plate 313 is provided above the slide 307; the detection plate 313 detects the position of the slide 307, and can also detect the positions of other components of the upper stop positioning mechanism, mainly to detect whether the upper stop positioning mechanism is moved by the upper stop. As for the priority choice of detecting the slide, it is because the slide is large in size and convenient for detection.

[0047] The frame is also provided with a positioning cylinder 314 of the upper stop positioning mechanism, and a positioning seat 315 corresponding to the positioning cylinder 314 is fixed on the slide 307. The positioning seat 315 is formed with a positioning groove 316 facing rearward, and the positioning cylinder 314 is arranged behind the positioning seat 315, and the protruding end of the positioning cylinder 315 is arranged toward the positioning groove 316. When the detection plate 313 detects that the upper stop positioning clamp reaches the set position, the protruding end of the positioning cylinder 314 is controlled to extend forward and abut against the positioning groove 316 to prevent the slide 307 from retreating; if the detection plate 313 does not detect the signal that the upper stop positioning clamp reaches the set position within the set time, the control device stops operating.

[0048] The upper stop side thrust mechanism 4 includes a push block 401 disposed behind the upper stop positioning clamp 301 and a push block cylinder 402 driving the push block 401 to move left and right. The push block cylinder 402 is fixedly connected to the slide seat 307 .

[0049] The extended end of the push block cylinder 402 is connected to a second guide seat 403 , a second guide rail 404 matching the second guide seat 403 is fixed on the slide seat 307 , and the push block 401 is fixedly connected to the second guide seat 403 .

Through the above arrangement, the push block 401 can push the upper stop more accurately, thereby improving the yield rate.

[0051] The block sensing mechanism 5 includes a sensing strip 501, which is rotatably arranged on a frame. The lower end of the sensing strip 501 is a sensing portion 502, which is arranged on the block chain channel 101 and has a spacing with the block chain channel 101 that is smaller than the height of the block 903. A detection switch 503 for detecting the position of the sensing strip is also provided on the frame.

[0052] The induction strip 501 is in an "L" shape, which includes a hinge section 504 and a sensing section 505. A hinge seat 506 is fixed on the frame, and a hinge slot 507 is formed on the hinge seat 506. The hinge section 504 is partially arranged in the hinge slot 507. A cover plate 508 is fixed on the outside of the hinge slot 507. A pin 509 is fixed in the middle of the hinge seat 506, passing through the hinge section 504 and the cover plate 508, so that the hinge section 504 can be rotatably connected in the hinge slot 507. The width of the hinge slot 507 is greater than the width of the hinge section 504, so that the hinge section 504 can rotate a certain distance in the hinge slot 507. The lower part of the induction section 505 is the induction part 502. The hinge section is arranged in the hinge slot, which can prevent the induction strip from being bounced too high and damaging the equipment when the block passes through the induction strip quickly during the high-speed operation of the equipment.

[0053] The rear of the sensing portion 502 is designed as an arc.

[0054] Working principle:

[0055] This patent application is applicable to a chain belt 9 that has been formed with both an upper stop 901 and a lower stop, and the chain insertion action is achieved by forming an oblique opening 902 on the upper stop 901 for the pull head to pass through. The chain belt includes two sub-chains, wherein the lower stop of the sub-chain used for chain insertion is formed with a square 903, and the upper stop is formed with an oblique opening 902; the lower stop of the other sub-chain is a latch 906, and the upper stop 901 is a normal upper stop.

[0056] When the chain belt 9 enters the device, it is in a split chain state. The split chain with the bevel 902 and the block 903 takes the block chain belt channel 101, and the split chain with the lower stop as the latch takes the latch chain belt channel 102. The block chain belt channel 101 is provided with an induction strip 501. When the chain belt moves under the traction of the traction device, the block 903 passes the induction strip 501 and lifts the induction strip 501. After the detection switch 503 detects the induction strip 501, it controls the telescopic cylinder 308 to extend the upper stop positioning clamp 301 and then controls the clamping cylinder 302 to move the two upper stops. The positioning clamp 301 is closed in the transition section 907 without chain teeth, and the chain belt traction device pulls the chain belt to continue to move forward. Since the width of the upper stop 901 is greater than the width of the chain tooth channel 303 in the upper stop positioning clamp 301, and the positioning clamp 301 is fixed on the slide 307, the front end of the upper stop 901 pushes against the side of the upper stop positioning clamp 301 and moves forward together until the detection plate 313 detects the signal that the upper stop positioning mechanism reaches the set position, and then controls the positioning cylinder 314 to extend and push against the upper stop positioning mechanism to prevent the slide 307 from being pulled backward by the tension spring 312;

[0057] Then the telescopic cylinder 308 controls the upper stop positioning clamp 301 to retract, pulling the block chain and the pin chain to create a gap for installing the slider, and then the upper slider mold rotates the slider by a certain angle and moves it upward to position the chain inlet of the slider to the side of the upper stop bevel 902. Then the upper stop positioning clamp 301 is released, and the push block 301 pushes the upper stop bevel 902 toward the chain inlet of the slider, so that the chain belt continues to move forward under the traction device, and the slider is fixed by the upper slider mold, and the slider moves in the chain belt until it reaches the lower stop position to complete the action of the upper slider.

[0058] If the upper stop 901 of the chain belt falls off, after the sensing pressure strip 501 detects the block 903, the upper stop positioning clamp 301 extends out and closes in the transition section 907, and the chain belt continues to move forward. However, since there is no upper stop 901 and the sprocket channel 303 on the positioning clamp 301 is larger than the width of the sprocket 905, the sprocket 905 on the chain belt passes directly through the sprocket channel 303 and cannot move forward with the upper stop positioning clamp 301. Therefore, if the detection plate 3131 does not detect that the upper stop positioning mechanism is in place within the set time, it is determined that there is no upper stop on the chain belt, and then the equipment is controlled to stop running to prevent equipment damage.

[0059] The invention has the characteristics of being able to effectively detect whether there is an upper stop on the chain belt, thereby preventing the equipment from being damaged due to the equipment still running without the upper stop.

[0060] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
