Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of zipper processing equipment, specifically relating to a zipper head rotation and conveying mechanism. Background Technology
[0002] Zippers consist of components such as the zipper tape, zipper teeth, zipper pull, top stop, and bottom stop. They are a common household item used in daily life, serving the function of joining or separating items. They are now widely used in clothing, bags, tents, and other products.
[0003] A zipper threading machine is a specialized device that automatically installs zipper heads onto zippers. For example, patent document CN212877989U discloses a zipper threading machine, which includes a frame, a zipper head traction device, a chain separating device, a zipper head conveying device, and a zipper head positioning device. The zipper head conveying device tractions the zipper, the chain separating device separates the left and right zipper straps, the zipper head conveying device delivers the zipper head to the zipper positioning device, and the zipper head positioning device pushes the zipper head to a designated position (on the zipper's travel path) between the left and right zipper straps. The zipper head traction device pulls the zipper forward, and the zipper head positioned on the zipper's travel path between the left and right zipper straps is threaded onto the zipper. However, this zipper head conveying device has a slow zipper head supply efficiency, requiring the zipper head positioning device to reset before the zipper head conveying device can deliver the zipper head again.
[0004] Automotive zippers are special zippers designed for the automotive environment, requiring higher standards in durability, strength, environmental adaptability, and safety. Automotive zippers have narrower and stiffer zipper tapes, and their zipper pulls are larger than regular zipper pulls, typically requiring manual threading, which is inefficient. While existing zipper threading machines can feed and thread regular zipper pulls, there is no specific, stable, and feasible solution for feeding concealed zipper pulls in automotive zippers. Utility Model Content
[0005] The purpose of this invention is to provide a zipper head rotating conveyor mechanism that can improve the conveying efficiency of zipper heads. It is also applicable to the automated conveying of concealed zipper heads for vehicles, and is stable and reliable.
[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:
[0007] A pull-head rotating conveying mechanism includes a rotating plate, which is equipped with a sliding receiving unit. The sliding receiving unit includes a slider, which is connected to the rotating plate via a slider guide rail. The slider reciprocates along the slider guide rail on the rotating plate. A pull-head receiving groove is provided at the front end of the slider. The slider is also equipped with an elastic component, which is used to allow the slider to slide back to its original position towards the rear end of the slider guide rail. The sliding receiving unit is equipped with a push rod, which is connected to a push rod power device. The push rod power device is used to drive the push rod to push the slider to slide towards the front end of the slider rail, causing the pull-head receiving groove to move to the pull-head position. The rotating plate is connected to a rotation power device, which is used to drive the rotating plate to rotate and transport the pull-head in the pull-head receiving groove to a designated position.
[0008] The rotary power unit drives the rotating plate to rotate, turning the sliding receiving unit to a horizontal position, with the opening of the pull head receiving slot facing upwards. The push rod power unit drives the push rod to move to the right, pushing the slider towards the pull head, causing the pull head receiving slot to move below the pull head (the pull head is supplied by a feed device or other similar device), and the pull head falls into the pull head receiving slot. The rotary power unit drives the rotating plate to rotate, turning the sliding receiving unit from a horizontal to a vertical position, rotating and sending the pull head to the insertion point, thus completing the insertion. After insertion, the push rod power unit drives the push rod to reset, and the elastic component causes the slider to slide along the slider guide rail to reset, thus starting the next work cycle; or after the pull head falls into the pull head receiving slot, if the sliding receiving unit is still in a horizontal state, the push rod power unit drives the push rod to reset, and then the rotary power unit drives the rotating plate to rotate again, transferring the pull head to the insertion point.
[0009] The push rod power unit can be mounted on the rotating plate and rotate synchronously with it; or it can be mounted independently on other components and not rotate with the rotating plate. When the push rod power unit is mounted independently on other components, it needs to first drive the push rod to reset, and then drive the rotating plate to rotate, to avoid the push rod interfering with the rotation of the sliding bearing unit.
[0010] In order to limit the position of the slider reset and to position the slider head receiving groove to facilitate the positioning of the slider head, the slider guide rail is provided with a reset limit block, and the elastic component is used to make the slider close to the reset limit block.
[0011] To prevent the slider from detaching from the slider receiving groove when not necessary, an elastic limiting component is provided at the opening of the slider receiving groove. The elastic limiting component is used to limit the slider within the slider receiving groove.
[0012] Preferably, the slider receiving groove includes a left slider groove and a right slider groove, which are arranged opposite to each other.
[0013] Preferably, a pull head support plate is provided at the bottom of the pull head receiving groove.
[0014] Preferably, the rotating plate is connected to a rotating power device via a rotating shaft, the rotating power device is mounted on the upright plate, the upright plate is provided with a rotating shaft hole for the rotating shaft to pass through, and the rotating plate and the rotating power device are located on opposite sides of the upright plate.
[0015] To locate the rotation position of the rotating plate and facilitate the orientation of the pull head receiving groove, the connecting shaft is equipped with a sensing plate, which is in conjunction with a sensor. By detecting the position of the sensing plate using the sensor, it is possible to confirm whether the rotating plate has rotated to the correct position, facilitating automated control of the rotating plate.
[0016] To further improve the conveying efficiency of the pull head and shorten the waiting time of the pull head, multiple sliding receiving units are provided, and the multiple sliding receiving units are evenly arranged along the circumference of the rotating plate.
[0017] Furthermore, the push rod is located between multiple sliding support units.
[0018] As one application of the pull head rotating conveyor mechanism, a feeder device is provided on the right side of the pull head rotating conveyor mechanism. The push rod power device drives the push rod to push the pull head receiving groove to the feeder device, and the pull head receiving groove receives the pull head falling from the feeder device. A pull head positioning device is provided below the pull head rotating conveyor mechanism. The rotation power device drives the rotating plate to rotate, and rotates and conveys the pull head in the pull head receiving groove to the pull head positioning device, and the pull head positioning device limits the pull head in the pull head receiving groove.
[0019] This invention, through a rotating plate and sliding receiving units, can not only receive the zipper pull but also rotate and transport it to a designated position. Multiple sliding receiving units reduce zipper pull waiting time and improve conveying efficiency. This invention is suitable for the automated conveying of concealed zipper pulls for vehicles, offering stability, reliability, and high conveying efficiency. Attached Figure Description

[0031] Figure 11 This is a schematic diagram of the positioning block structure. Detailed Implementation
[0032] like Figure 1-11 As shown, a pull head rotating conveyor mechanism is provided on the upright plate 1, a feed head device 5 is provided on the right side of the pull head rotating conveyor mechanism, and a pull head positioning device 6 is provided below the pull head rotating conveyor mechanism.
[0033] like Figure 1-6 As shown, the pull head rotating conveying mechanism includes a rotating plate 2, which is connected to a connecting shaft 21. The connecting shaft 21 is connected to a rotating power device 22, which is a servo motor 22 (or other similar rotating power device). The upright plate 1 is provided with a shaft hole for the connecting shaft 21 to pass through. The connecting shaft 21 is located in the shaft hole. The rotating plate 2 and the servo motor 22 are located on both sides of the upright plate 1, and the rotating power device 22 is used to drive the rotating plate 2 to rotate.
[0034] The rotating plate 2 is equipped with four sliding support units (31, 32, 33, and 34 in Figure 3). These four sliding support units are evenly distributed around the circumference of the rotating plate 2, with an included angle of 90° between adjacent units. Specifically, the rotating plate 2 includes a rotating disk, around which four slider mounting plates are evenly distributed around the circumference of the rotating disk, with an included angle of 90° between adjacent plates. The four sliding support units are respectively mounted on the four slider mounting plates. Alternatively, the four sliding support units can be directly mounted on the rotating disk, evenly distributed around its circumference. The rotating plate 2 can also have one or more sliding support units. When there are multiple (no fewer than two) sliding support units, to facilitate positioning of each unit and automatic control, the multiple sliding support units are evenly distributed around the circumference of the rotating plate 2, meaning the included angle between adjacent units is equal, to control each rotation of the rotating plate.
[0035] like Figure 4-6 As shown, taking the horizontal sliding receiving unit 32 as an example, the sliding receiving unit includes a slider 8. The slider 8 is connected to the rotating plate 2 via a slider guide rail 81. The slider 8 slides back and forth on the rotating plate 2 along the slider guide rail 81. A reset limiting block 84 is provided at the rear end of the slider guide rail 81. The slider 8 is provided with an elastic component, which is a spring (or other similar elastic component). One end of the spring is connected to the slider 8, and the other end is connected to the reset limiting block 84. The spring causes the slider 8 to slide back to the rear end of the slider guide rail 81. In a preferred embodiment, the spring causes the slider 8 to come close to the reset limiting block 84.
[0036] The front end of the slider 8 is provided with a pull head receiving groove 82, the opening of which faces upward. Specifically, the pull head receiving groove 82 includes a left pull head groove 821 and a right pull head groove 822, which are arranged opposite to each other. A support part 823 is provided at the bottom of the pull head receiving groove 82. The left pull head groove 821 is used to limit the left side of the pull head, the right pull head groove 822 is used to limit the right side of the pull head, and the support part 823 is used to support the bottom of the pull head and prevent it from falling off the bottom of the pull head receiving groove 82.
[0037] To prevent the slider from detaching from the slider receiving groove 82 unnecessarily, an elastic limiting component 83 is provided at the opening of the slider receiving groove 82. The elastic limiting component 83 is a ball-head plunger, which is located at the left slider groove 821. The ball-head plunger 83 is used to limit the slider within the slider receiving groove 82, preventing the slider from detaching 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, with a pin installed in the pin hole. The pin slides back and forth along the pin hole, and a spring is provided at the tail end of the pin. The spring pushes the head end of the pin 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 squeeze, the spring returns to its original position, allowing the head end of the pin to re-extend from the pin hole.
[0038] The sliding support units 31, 33, and 34 have the same structure as the sliding support unit 32, and will not be 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, which is connected to the upright plate 1 via 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 towards the front end of the slider guide rail 81, causing the pull head receiving groove 82 to move to the right to the end of the feed head device 5. The pull head receiving groove 82 receives the pull head falling from the feed head device 5. The push rod power device 41 drives the push rod 4 to reset. The elastic component causes the slider 8 to slide along the slider guide rail 81 towards the reset limit block 84 to reset.
[0040] The push rod 4 is positioned between the four sliding receiving units. When the sliding receiving unit 32 rotates to a horizontal position and is located between the push rod 4 and the feeding device 5, the push rod power device 41 drives the push rod. The push rod pushes the slider of the sliding receiving unit 32, and the slider slides along the slider guide rail, pushing the pull head receiving groove of the sliding receiving unit 32 to the end of the feeding device 5 so that the sliding receiving unit 32 can receive the pull head falling from the feeding device 5. Similarly, when the sliding receiving unit 31, 33, or 34 rotates between the push rod 4 and the feeding device 5, the push rod power device 41 can also drive the push rod to push the corresponding sliding slider, pushing its pull head receiving groove 82 to the end of the feeding device 5 to receive the pull head falling from the feeding device 5.
[0041] like Figure 3 As shown, the reset spring includes a first reset spring 35 and a second reset spring 36. One end of the first reset spring 35 is connected to the slider of the first sliding support unit 31, and the other end is connected to the slider of the third sliding support unit 33. One end of the second reset spring 36 is connected to the slider of the second sliding support unit 32, and the other end is connected to the slider of the fourth sliding support unit 34.
[0042] Of course, each of the four sliding bearing units can be equipped with a push rod and a push rod power device. All four push rod power devices are set on the rotating plate 2 and rotate with the rotating plate 2. That is, the rotating plate 2 is equipped with four push rod power devices, and each push rod power device is equipped with a push rod. The four push rod power devices are used to drive the four sliding bearing units respectively.
[0043] The rotating power device 22 drives the rotating plate 2 to rotate, turning any sliding receiving unit to a horizontal position, located between the push rod 4 and the feeding device 5. The slider guide rail of the sliding receiving unit is turned to a horizontal position. The push rod power device drives the push rod to push the slider to the right, pushing the pull head receiving groove to the end of the feeding device. The pull head falling from the feeding device is received by the pull head 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 (towards the reset limit block) and reset, fitting tightly against the reset limit block. The rotating power device drives the rotating plate to rotate, turning the sliding receiving unit from a horizontal to a vertical position, causing the pull head receiving groove to rotate above the pull head positioning device 6. The pull head positioning device 6 limits the pull head in the pull head receiving groove, thus completing the threading.
[0044] To detect the rotation of the rotating plate 2 and confirm whether the sliding support unit has rotated into place, four sensing plates 23 are provided on the connecting shaft 21. The four sensing plates 23 are evenly arranged along the circumference of the connecting shaft, and the included angle between adjacent sensing plates is 90°. A sensor 24 is provided on the vertical plate 1. The sensor 24 is a photoelectric switch (or other sensor with the same function). The photoelectric switch senses the position of the sensing plates 23 to confirm whether the sliding support unit has rotated into place. When there are three or fewer or more sliding support units, the sensing plates 23 can be adaptively adjusted according to the number of sliding support units to monitor the rotation of the rotating plate 2.
[0045] like Figure 7-10 As shown, the feeding device includes a feeder slide 51. The vibratory feeder causes the feeder heads to enter the feeder slide 51 in an orderly manner, and the feeder heads slide down the feeder slide 51 into the feeder head receiving groove.
[0046] To limit the slider in the slider groove 5 and prevent it from slipping unnecessarily, a slider limiting block hole 91 is provided on the side wall of the slider groove 51. A slider limiting block 92 is provided inside the slider limiting block hole 91. The slider limiting block 92 slides back and forth along the slider limiting block hole 91. The head end of the slider limiting block 92 is arc-shaped and protrudes from the inner wall of the slider groove 51. A spring is provided at the tail end of the slider limiting block 92. The spring is used to reset the slider limiting block 92 from protruding from the inner wall of the slider groove 51. When the slider is subjected to force and passes through the slider limiting block 92, the slider limiting block 92 is retracted into the slider limiting 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 head end of the slider limiting block 92 to protrude from the inner wall of the slider groove 5, thus limiting the next slider.
[0047] In order to push the slider head through the slider head limiting block hole 91, a slider head push plate 52 is provided in the slider head slide 51. The slider head push plate 52 is connected to a power device. The power device drives the slider head push plate 52 to push the slider head in the slider head slide 51 so that the slider head passes through the slider head limiting block hole 91.
[0048] In another embodiment, the pull head groove 51 is provided with a feed push plate 52, which is mounted on the feed rod 53. The feed rod 53 is provided with a rotating rod 54, which is located on the same side as the feed push plate 52. The rotating rod 54 is mounted in the rotating rod hole of the feed mounting plate 56 and is rotatably connected to the feed mounting plate 56 through the rotating rod shaft 55. A tension spring 57 is provided between the feed rod 53 and the feed mounting plate 56. The feed rod 53 rotates around the rotating rod shaft 55, so that after the feed push plate 52 is inserted into the pull head groove 51, the tension spring is used to reset the feed rod 53 by rotating around the rotating rod shaft 55.
[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, which has a downward guide portion 591 and a translational guide portion 592. When the feed mounting plate 56 moves, the downward guide portion 591 presses against the guide rod 58, and the feed rod 53 rotates on the feed mounting plate 56 around the rotating shaft 55. The head end of the feed push plate 52 extends into the pull head slide groove 51. When the feed mounting plate 56 drives the guide rod 58 to move along the translational guide portion 592, the feed push plate 52 pushes the pull head to move in the pull head slide groove 51. The pull head slides down from the pull head slide groove 51 to the pull head receiving groove through the pull head limiting block 92. When the feed mounting plate 56 returns to its original position, the tension spring causes the feed rod 53 to rotate and return to its original position on the feed mounting plate 56 around the rotating shaft 55, causing the feed push plate 52 to disengage from the pull head slide groove 51.
[0050] The push plate pushes the slider head to move within the slider head groove. The slider head presses against the slider head limiting block, causing the limiting block to retract into its hole. After passing the limiting block, the slider head slides out of the groove, where it is caught by a receiving groove. Once the limiting block is freed from the slider head's pressure, a return spring causes it to automatically protrude from the side wall of the slider head groove.
[0051] To achieve the reciprocating motion of the feeder mounting plate 56, the feeder mounting plate 56 is provided with a feeder guide rail 561 and a feeder power device 562. The feeder power device 562 is a cylinder. The feeder power device 562 drives the feeder mounting plate 56 to move back and forth along the feeder guide rail 561 to achieve the movement of the feeder mounting plate 56.
[0052] Of course, the feeding device can also be a common feeding device in the existing technology.
[0053] like Figure 1 , 2 As shown in Figures 6 and 11, the zipper head positioning device includes a positioning block 61, which is mounted 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, which drives the positioning seat 62 to slide back and forth along the positioning guide rail 63, moving the positioning block 61 away from / towards the zipper head 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 zipper head groove 821 and the right zipper head groove 822 to position the tail of the zipper head. The second positioning block 612 is used to extend between the left zipper head groove 821 and the right zipper head groove 822 to position the head of the zipper head. The protrusion 613 is used to abut against the front end of the zipper head to prevent the zipper head from shifting along the groove opening direction of the zipper head receiving groove. The rotating device drives the rotating plate to rotate. After the zipper head receiving groove rotates to above the positioning block, the positioning block power device drives the positioning block to approach the zipper head. The zipper tab is located between the first positioning block and the second positioning block. The first positioning block pushes the tail of the zipper head, and the second positioning block pushes the head of the zipper head, thereby clamping the zipper head and positioning it. The zipper head conveying device pulls the zipper zipper head forward, thus threading the zipper head onto the zipper. Of course, the zipper head positioning device can also adopt the zipper head positioning device mechanism commonly used in existing technology.
[0054] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
