Description

Technical Field

[0001] The invention belongs to the technical field of zipper processing devices, and particularly relates to a slider rotating and conveying mechanism. Background Art

[0002] Zippers consist of chain tape, chain teeth, sliders, top stops, bottom stops and other components. They are a type of daily necessity that people often use in their daily lives. They have the function of combining or separating items and are now widely used in products such as clothing, bags, and tents.

[0003] A zipper threading machine is a special device for automatically installing a slider onto a zipper. For example, the patent document with the authorization announcement number CN212877989U discloses a zipper threading machine, which includes a frame, a slider traction device, a chain splitting device, a slider conveying device and a slider positioning device. The slider conveying device is used to pull the zipper forward, the chain splitting device is used to separate the left and right chain belts of the zipper, the slider conveying device is used to convey the slider to the zipper positioning device, and the slider positioning device is used to push the slider to a specified position (on the zipper travel path) and is located between the left and right chain belts. The slider traction device pulls the zipper forward, is located on the zipper travel path, and the slider located between the left and right chain belts will be threaded onto the zipper. However, the slider supply efficiency of the slider conveying device is slow, and it is necessary to wait for the slider positioning device to reset before the slider conveying device can convey the slider again.

[0004] Automotive zippers are specialized zippers designed for automotive environments, demanding higher levels of durability, strength, environmental adaptability, and safety. Their tape is narrow and rigid, and their sliders are larger than conventional sliders. Threading these sliders is typically done manually, resulting in low efficiency. While existing zipper threading machines can deliver and thread conventional sliders, there's no reliable and robust solution for delivering invisible sliders for automotive zippers. Summary of the Invention

[0005] The purpose of the present invention is to provide a slider rotating conveying mechanism, which can improve the conveying efficiency of the slider and is also suitable for the automatic conveying of invisible sliders for vehicles, which is stable and reliable.

[0032] like Figure 1-11 As shown, a pull head rotating and conveying mechanism is provided on the vertical plate 1, a pull head feeding device 5 is provided on the right side of the pull head rotating and conveying mechanism, and a pull head positioning device 6 is provided below the pull head rotating and conveying mechanism.

[0033] like Figure 1-6 As shown, the pulling head rotating conveying mechanism includes a rotating plate 2, which is connected to a connecting shaft 21, and the connecting shaft 21 is connected to a rotating power device 22. The rotating power device is a servo motor 22 (or other rotating power devices of the same type). The vertical plate 1 is provided with a rotating shaft hole for the connecting shaft 21 to pass through. The connecting shaft 21 is located in the rotating shaft hole. The rotating plate 2 and the servo motor 22 are respectively located on both sides of the vertical plate 1. The rotating power device 22 is used to drive the rotating plate 2 to rotate.

[0034] The rotating plate 2 is provided with four sliding receiving units (such as 31, 32, 33, and 34 in Figure 3). The four sliding receiving units are evenly arranged along the circumference of the rotating plate 2, and the angle between adjacent sliding receiving units is 90°. Specifically, the rotating plate 2 includes a rotating disk, and four slider mounting plates are provided around the rotating disk. The four slider mounting plates are evenly arranged along the circumference of the rotating disk, and the angle between adjacent slider mounting plates is 90°. The four sliding receiving units are respectively provided on the four slider mounting plates. Of course, the four sliding receiving units can also be directly provided on the rotating disk and evenly arranged along the circumference of the rotating disk. Of course, the rotating plate 2 can also be provided with one sliding receiving unit, or more than two sliding receiving units. When there are multiple sliding receiving units (not less than two), in order to facilitate the positioning of each sliding receiving unit and facilitate automated control, the multiple sliding receiving units are evenly arranged along the circumference of the rotating plate 2, that is, the angles between adjacent sliding receiving units are equal, so as to control each rotation of the rotating plate.

[0035] like Figure 4-6 As shown, taking the sliding receiving unit 32 in a horizontal state as an example, the sliding receiving unit includes a slider 8, which is connected to the rotating plate 2 via a slider guide 81. The slider 8 slides back and forth on the rotating plate 2 along the slider guide 81. A reset limit block 84 is provided at the rear end of the slider guide 81. The slider 8 is provided with an elastic component, which is a spring (or other elastic component of the same type). One end of the spring is connected to the slider 8 and the other end is connected to the reset limit block 84. The spring causes the slider 8 to slide and reset toward the rear end of the slider guide 81. As a preferred embodiment, the spring causes the slider 8 to approach the reset limit block 84.

[0036] The front end of the slider 8 is provided with a slider receiving groove 82, and the slider receiving groove 82 opens upward. Specifically, the slider receiving groove 82 includes a left slider groove 821 and a right slider groove 822. The left slider groove 821 and the right slider groove 822 are arranged opposite each other. A supporting portion 823 is provided at the bottom of the slider receiving groove 82. The left slider groove 821 is used to limit the left side of the slider, and the right slider groove 822 is used to limit the right side of the slider. The supporting portion 823 is used to support the bottom of the slider to prevent the slider from falling off from the bottom of the slider receiving groove 82.

[0037] In order to prevent the slider from being separated from the slider receiving groove 82 when not necessary, an elastic limiting component 83 is provided at the notch of the slider receiving groove 82. The elastic limiting component 83 is a ball plunger, which is provided at the left slider groove 821. The ball plunger 83 is used to limit the slider in the slider receiving groove 82 to prevent the slider from being separated from the slider receiving groove 82. Of course, the elastic limiting component 83 can also be a common elastic limiting component, such as a pin hole provided on the side wall of the slider receiving groove 82, a pin provided in the pin hole, the pin sliding back and forth along the pin hole, a spring provided at the tail end of the pin, the spring pushes the pin head end out of the pin hole, when the pin is squeezed by the slider, the pin retracts into the pin hole to avoid the slider (at this time, the spring is compressed and deformed), when the pin is freed from the squeezing, the spring resets the pin head end to extend out of the pin hole again.

[0038] The sliding receiving units 31 , 33 , 34 have the same structure as the sliding receiving unit 32 and are not described separately here.

[0039] A push rod 4 is provided between the four sliding receiving units. The push rod 4 is connected to a push rod power device 41. The push rod power device 41 is connected to the vertical plate 1 through a bracket. The push rod power device 41 is a cylinder (or other similar power device). The cylinder drives the push rod 4 to move to the right. The push rod 4 pushes the slider 8 to slide toward the front end of the slider guide rail 81, causing the slider receiving groove 82 to move to the right to the end of the head delivery device 5. The slider receiving groove 82 receives the slider dropped by the head delivery device 5. The push rod power device 41 drives the push rod 4 to reset, and the elastic component causes the slider 8 to slide along the slider guide rail 81 toward the reset limit block 84 to reset.

[0040] The push rod 4 is arranged between the four sliding receiving units. When the sliding receiving unit 32 rotates to the horizontal direction and is located between the push rod 4 and the head feeding device 5, the push rod power device 41 drives the push rod, and the push rod pushes the slider of the sliding receiving unit 32. The slider slides along the slider guide rail and pushes the slider receiving groove of the sliding receiving unit 32 to the end of the head feeding device 5, so that the sliding receiving unit 32 receives the slider dropped from the head feeding device 5. Similarly, when the sliding receiving unit 31 or the sliding receiving unit 33 or the sliding receiving unit 34 rotates to between the push rod 4 and the head feeding device 5, the push rod power device 41 can also drive the push rod to push the corresponding sliding slider so that the slider receiving groove 82 is pushed to the end of the head feeding device 5 to receive the slider dropped from the head feeding device 5.

[0041] like Figure 3 As shown, the return spring includes a first return spring 35 and a second return spring 36, one end of the first return spring 35 is connected to the slider of the first sliding receiving unit 31, and the other end is connected to the slider of the third sliding receiving unit 33, one end of the second return spring 36 is connected to the slider of the second sliding receiving unit 32, and the other end is connected to the slider of the fourth sliding receiving unit 34.

[0042] Of course, the four sliding supporting units can be individually provided with push rods and push rod power devices, and the four push rod power devices are all provided on the rotating plate 2 and rotate with the rotating plate 2; that is, the rotating plate 2 is provided with four push rod power devices, and the push rod power device is provided with push rods, and the four push rod power devices are respectively used to drive the four sliding supporting units.

[0043] The rotating power device 22 drives the rotating plate 2 to rotate, rotating any sliding receiving unit to the horizontal direction, located between the push rod 4 and the head feeding device 5, and the slider guide rail of the sliding receiving unit is turned to the horizontal direction. The push rod power device drives the push rod to push the slider to the right, pushing the slider receiving groove to the end of the head feeding device, and the slider dropped by the head feeding device is received by the slider receiving groove. The push rod power device drives the push rod to reset, and the elastic component causes the slider to slide to the left (the reset limit block side) and reset, and close to the reset limit block. The rotating power device drives the rotating plate to rotate, turning the sliding receiving unit from the horizontal direction to the vertical direction, rotating the slider receiving groove to the top of the slider positioning device 6, and the slider positioning device 6 limits the slider in the slider receiving groove, thereby completing the head threading.

[0044] In order to detect the rotation of the rotating plate 2 and confirm whether the sliding receiving unit has rotated into place, the connecting shaft 21 is provided with four sensing plates 23. The four sensing plates 23 are evenly arranged along the circumference of the connecting shaft, and the angle between adjacent sensing plates is 90 degrees. The vertical plate 1 is provided with a sensor 24. The sensor 24 is a photoelectric switch (or other sensor with the same function). The photoelectric switch senses the position of the sensing plate 23 to confirm whether the sliding receiving unit has rotated into place. When there are less than three or more than five sliding receiving units, the sensing plates 23 can be adaptively adjusted according to the number of sliding receiving units to monitor the rotation of the rotating plate 2.

[0045] like Figure 7-10 As shown, the head feeding device includes a slider chute 51, and the vibration plate feeding device allows the sliders to enter the slider chute 51 in an orderly manner, and the sliders slide along the slider chute 51 and fall into the slider receiving groove.

[0046] In order to limit the position of the slider in the slider chute 5 and prevent it from sliding off when not necessary, a slider limit block hole 91 is provided on the side wall of the slider chute 51. A slider limit block 92 is provided in the slider limit block hole 91. The slider limit block 92 slides back and forth along the slider limit block hole 91. The leading end of the slider limit block 92 is arc-shaped, and the arc-shaped shape of the slider limit block 92 protrudes from the inner wall of the slider chute 51. The trailing end of the slider limit block 92 is provided with a spring, which is used to reset the slider limit block 91 so that it protrudes from the inner wall of the slider chute 51. When the slider is forced to pass through the slider limit block 92, the slider limit block 92 is forced to retract into the slider limit block hole 91, at which time the spring is compressed and deformed; after the slider passes through, the spring returns to its original shape, causing the leading end of the slider limit block 92 to extend out of the inner wall of the slider chute 5, thereby limiting the position of the next slider.

[0047] In order to push the sliding head through the sliding head limit block hole 91, a sliding head push plate 52 is provided in the sliding head slide 51, and the sliding head push plate 52 is connected to a power device. The power device drives the sliding head push plate 52 to push the sliding head in the sliding head slide 51 so that the sliding head passes through the sliding head limit block hole 91.

[0048] As another embodiment, the pulling head slide 51 is provided with a head feeding push plate 52, and the head feeding push plate 52 is provided on the head feeding rod 53. The head feeding rod 53 is provided with a rotating rod 54. The rotating rod 54 and the head feeding push plate 52 are located on the same side of the head feeding rod 53. The rotating rod 54 is provided in the rotating rod hole of the head feeding mounting plate 56, and is rotatably connected to the head feeding mounting plate 56 through the rotating rod rotating shaft 55. A tension spring 57 is provided between the head feeding rod 53 and the head feeding mounting plate 56. The head feeding rod 53 rotates around the rotating rod rotating shaft 55 as the axis, so that after the head feeding push plate 52 is inserted into the pulling head slide 51, the tension spring is used to rotate and reset the head feeding rod 53 around the rotating rod rotating shaft 55 as the axis.

[0049] A guide rod 58 is provided on one side of the feed rod 53. The guide rod 58 is provided with a guide pressure plate 59. The guide pressure plate 59 has a downward guide portion 591 and a translation guide portion 592. When the feed mounting plate 56 moves, the downward guide portion 591 presses the guide rod 58. The feed rod 53 rotates on the feed mounting plate 56 with the rotating rod shaft 55 as the axis. The head end of the feed push plate 52 extends into the slider chute 51. When the feed mounting plate 56 drives the guide rod 58 along the translation guide portion 592, the feed push plate 52 pushes the slider to move in the slider chute 51. The slider passes through the slider limit block 92 and slides from the slider chute 51 to the slider receiving groove. When the feed mounting plate 56 is reset, the tension spring causes the feed rod 53 to rotate and reset on the feed mounting plate 56 with the rotating rod shaft 55 as the axis, causing the feed push plate 52 to disengage the slider chute 51.

[0050] The push plate pushes the slider forward in the slider chute. The slider presses against the slider stopper, which retracts into the stopper hole. After the slider passes through the stopper, it slides down the slider chute and is received by the slider receiving groove. After the slider stopper is freed from the pressure of the slider, the stopper's return spring allows the slider stopper to automatically protrude from the side wall of the slider chute.

[0051] In order to realize the reciprocating motion of the head feeding mounting plate 56, the head feeding mounting plate 56 is provided with a head feeding guide rail 561 and a head feeding power device 562. The head feeding power device 562 is a cylinder. The head feeding power device 562 drives the head feeding mounting plate 56 to move back and forth along the head feeding guide rail 561 to realize the movement of the head feeding mounting plate 56.

[0052] Of course, the head feeding device can also adopt the head feeding device commonly used in the prior art.

[0053] like Figure 1 、 2 As shown in Figures 6 and 11, the slider positioning device includes a positioning block 61, which is arranged on a positioning seat 62. The positioning seat 62 is provided with a positioning guide rail 63 and a positioning block power device 64. The positioning block power device 64 is a cylinder. The positioning block power device 64 drives the positioning seat 62 to slide back and forth along the positioning guide rail 63, and the positioning block 61 moves away from / close to the slider receiving groove 82. The positioning block 61 includes a first positioning block 611 and a second positioning block 612. The end of the second positioning block 612 is provided with a protrusion 613. The first positioning block 611 is used to extend between the left slider groove 821 and the right slider groove 822 to position the tail of the slider. The second positioning block 612 is used to extend between the left slider groove 821 and the right slider groove 822 to position the head of the slider. The protrusion 613 is used to resist the front end of the slider to prevent the slider from moving along the notch direction of the slider receiving groove. The rotating device drives the rotating plate to rotate. After the slider receiving groove rotates to the top of the positioning block, the positioning block power device drives the positioning block to approach the slider. The pull tab is located between the first positioning block and the second positioning block. The first positioning block pushes against the tail of the slider, and the second positioning block pushes against the head of the slider, thereby clamping the slider and positioning the slider. The slider conveying device pulls the zipper past the slider and then inserts the slider onto the zipper. Of course, the slider positioning device can also adopt the slider positioning device mechanism commonly used in the prior art.

[0054] The above embodiments do not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
