Pull head slide rail and pull head conveyor

Abstract

This utility model discloses a pull head slide rail, including pull head grooves on both sides, which are arranged opposite to each other and spaced apart. The pull head conveying device includes a pull head slide rail with a pull head release port. A gripper is located at the release port, and the gripper has a gripper power device. The gripper is mounted on a lifting seat, which has a lifting power device. The lifting seat is mounted on a traveling seat, which has a traveling power device. The gripper holds the pull head at the release port, and the lifting power device drives the lifting seat to move on the traveling seat, causing the pull head held by the gripper to release from the release port. The traveling power device drives the traveling seat to move, thus pushing the pull head to the next process. This utility model, through its double-groove spacing structure, ensures that the pull rope always travels within the hollow channel between the double grooves. Regardless of whether the pull rope is located at the front, back, or exposed in both directions of the pull head, it avoids rigid contact with the slide rail, thereby eliminating problems such as jamming and posture deviation caused by traditional enclosed slide rails, significantly improving the smoothness and reliability of the rope-shaped pull head conveying. This invention can not only convey pull heads with rope-like pull tabs, but is also applicable to conventional pull heads, thus improving the applicability of the equipment.

Description

Technical Field

[0001] This utility model belongs to the technical field of zipper production equipment, specifically relating to a zipper pull slide rail. This utility model also relates to a zipper pull conveying device. Background Technology

[0002] As consumers increasingly demand a unified look for fabric products such as clothing and sofas, zipper pull designs are constantly evolving. Some zipper pulls have transitioned from traditional metal tabs to cord-like structures. For example, Chinese Patent CN210747609 U discloses an invisible zipper pull. The zipper pull has a base core between its lower and upper base plates for joining or separating the chains. The area of ​​the upper base plate is smaller than that of the lower base plate. Side guide plates are provided on both sides of the lower base plate, and a top limiting plate is fixedly installed on the top of the side guide plates. The top limiting plate cooperates with the upper base plate to press the chain from above, while the lower base plate is used to press the chain from below. The side guide plates and the base core cooperate to guide the chain from the side. A pull hole is provided on the upper base plate, and a pull rope is movably inserted into the pull hole. The pull rope can be pulled horizontally within the pull hole, and the diameters at both ends of the pull rope are larger than the inner diameter of the pull hole, preventing the pull rope from completely detaching from the pull hole. In use, the pull rope is pulled upwards from the upper base plate, and the user pulls the top end of the pull rope. The bottom end of the pull rope is limited by the pull hole, causing the zipper pull to move along the two chains, closing or opening the chains. When not in use, the pull rope is slid downwards, with only the upper end of the pull rope exposed. The key feature is that the pull tab of the zipper head has a rope-like structure, and the pull rope can slide freely back and forth in the pull hole. It can slide to the upper bottom plate side and be exposed on the front of the zipper head (upper bottom plate side), or slide to the lower bottom plate side and be exposed on the back of the zipper head (lower bottom plate side), or both the front and back sides can be exposed at the same time.

[0003] In automated production, zipper threading machines are automated devices that automatically thread zipper heads into zipper belts. Their zipper head guide rails connect the feeding system (such as the vibratory feeder outlet) and the threading actuator, primarily functioning to maintain the correct posture of the zipper head and ensure continuous and stable conveying. Conventional zipper head guide rails typically employ an inclined, open slot-like structure (feed trough) with the opening facing downwards. The zipper head slides within the slot using its own weight or auxiliary force (such as track vibration), while the zipper tab naturally hangs down outside the slot. Ultimately, the zipper head arrives at the end of the track in a specific posture (usually with the back facing up and the tab facing down) for subsequent threading operations. For example, Chinese Patent No. CN 220859589 U discloses a zipper pull pusher mechanism, which includes a support frame, a feeding track, and a pusher device. The feeding track is connected to the support frame, and the pusher device is installed at one end of the feeding track. The feeding track includes a connecting frame, a feeding trough, and a discharge port. The connecting frame connected to the vibrating plate is installed on the top of the feeding track. A feeding trough is opened on one side of the feeding track, and a discharge port for pushing out the zipper pull is provided at one end of the feeding trough. The feeding track is connected to the vibrating plate. The zipper pull on the vibrating plate can be transported to the discharge port at one end of the feeding track by means of the feeding trough opened on the feeding track. Then, the pusher device pushes out the puller for feeding and installation.

[0004] However, the conventional feed trough structure described above typically has a closed plate-like back. When applied to the aforementioned pull head with rope-like pull tabs, it presents significant drawbacks: the position of the pull rope on the pull head is not fixed. Upon entering the feed trough, the pull rope may be exposed on the front or back of the pull head, or even both simultaneously. If the pull rope happens to be exposed on the back of the pull head (i.e., the side facing the back of the feed trough) upon entering the feed trough, it is prone to spatial interference with the closed back of the feed trough. This interference can disrupt the pull head's posture upon entering the feed trough, leading to anything from incorrect posture and poor conveying to complete blockage at the feed trough's inlet. Even if the pull head can enter the feed trough smoothly, the pull rope on the back of the pull head can still cause spatial interference with the back of the feed trough, further affecting the pull head's conveying. Therefore, existing conventional pull head slide rail structures cannot effectively adapt to and reliably convey the new type of pull head with rope-like pull tabs, limiting the application of such pull heads in automated production. Utility Model Content

[0005] The purpose of this invention is to provide a slider rail that is suitable not only for conveying sliders with rope-like pull tabs, but also for conveying conventional sliders. Additionally, this invention provides a slider conveying device to achieve automatic slider pushing.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0007] The slider rail includes a left slider groove and a right slider groove, which are arranged opposite to each other and have a gap between them. The left side of the slider slides along the left slider groove, and the right side of the slider slides along the right slider groove. The gap between the left and right slider grooves is used for the passage of the pull rope.

[0008] The gap between the left and right slider grooves is designed to avoid the pull rope, allowing it to smoothly enter the slider rail regardless of whether the pull rope is exposed on the front or back of the slider, or both. Even if the pull rope rubs against the slider rail, it does not easily affect the conveying posture of the slider, effectively adapting to and reliably conveying new types of sliders with rope-like pull tabs.

[0009] Furthermore, the left pull head slide groove and the right pull head slide groove are connected to the slide rail mounting base, and the slider mounting base is provided with a pull rope avoidance cavity, which is located in the extended space of the distance between the left pull head slide groove and the right pull head slide groove.

[0010] A pull head conveying device includes a pull head slide rail, which includes a left pull head slide groove and a right pull head slide groove. The left pull head slide groove and the right pull head slide groove are arranged opposite to each other and have a gap between them. The left side of the pull head slides along the left pull head slide groove, and the right side of the pull head slides along the right pull head slide groove. The gap between the left pull head slide groove and the right pull head slide groove is used for the pull rope to pass through.

[0011] The slider rail is provided with a slider release port, the slider release port is provided with a gripper, the gripper is provided with a gripper power device, the gripper is provided on a lifting seat, the lifting seat is provided with a lifting power device, the lifting seat is provided on a traveling seat, and the traveling seat is provided with a traveling power device. The gripper holds the slider at the slider release port, the lifting power device drives the lifting seat to move on the traveling seat, so that the slider held by the gripper releases from the slider release port, and the traveling power device drives the traveling seat to move, thereby pushing the slider to the next process (such as the slider positioning and threading process).

[0012] The end of the slider rail is provided with a rail mounting base. The left slider groove and the right slider groove are connected to the rail mounting base. The rail mounting base is provided with a left baffle and a right baffle. The left baffle and the right baffle form a slider groove. The slider release port is located on the slider groove.

[0013] In order to stop the tail of the pull head and limit the pull head at the pull head release point, a stop block is provided in the pull head slide groove.

[0014] To prevent the slider from tilting to the left or right and to correct its posture, while also limiting the slider to the slider release point, the left baffle has a left guide block for the slider, and the right baffle has a right guide block for the slider.

[0015] In order to avoid the pull cord on the back of the slider, the slider mounting base is provided with a pull cord avoidance cavity, which is located in the extended space between the left slider groove and the right slider groove.

[0016] To limit the zipper pull at the release point and prevent it from detaching unnecessarily, while also allowing it to detach, a flexible limiting component (made of soft glass, rubber, or other flexible material) is provided at the release point. When the zipper pull detaches, the flexible limiting component deforms to allow it to detach; after detachment, the flexible limiting component returns to its original shape, thus limiting the next zipper pull.

[0017] Furthermore, the flexible limiting component includes a left flexible limiting component and a right flexible limiting component. The left flexible limiting component is used to limit the left side of the slider, and the right flexible limiting component is used to limit the right side of the slider.

[0018] This invention utilizes a double-groove spacing structure (the left and right grooves are arranged opposite each other with a pre-reserved gap in the middle) to ensure that the pull rope always travels within the hollow channel between the double grooves. Regardless of whether the pull rope is located at the front, back, or exposed in both directions of the pull head, it avoids rigid contact with the slide rail, thus eliminating problems such as jamming and posture deviation caused by traditional enclosed slide rails. This significantly improves the smoothness and reliability of the rope-type pull head's conveying performance. Furthermore, the double-groove spacing structure does not restrict the extension direction of the pull rope, nor does it rely on a preset posture of the pull rope. Even if the pull rope rubs against the grooves, it will not interfere with the posture of the pull head itself.

[0019] This invention features an adjustable baffle to accommodate zipper pulls of different sizes. Its flexible limiting component dynamically balances the needs of limiting and disengaging, preventing accidental detachment of the zipper pull under normal conditions and releasing it through elastic deformation during clamping. The invention utilizes a three-axis driven gripper system to precisely grasp the zipper pull located at the disengagement point and transfer it to the next insertion station. This design actively eliminates interference from the pull rope on the zipper pull's conveying posture, ensuring the zipper pull enters the insertion process in a stable posture, thus achieving automated insertion of rope-type pull tab zipper pulls.

[0020] This invention can not only convey pull heads with rope-like pull tabs, but is also applicable to conventional pull heads, thus improving the applicability of the equipment. Attached Figure Description

[0023] Figure 2 This is a schematic diagram of the slide rail mounting base structure.

[0024] Figure 3 This is a schematic diagram of the baffle structure.

[0025] Figure 4 This is a schematic diagram of part of the pull head conveyor device. Detailed Implementation

[0026] like Figure 1-2 As shown, the zipper slide rail includes a left zipper slide groove 11 and a right zipper slide groove 12, which are connected to the slide rail mounting base 2. The left zipper slide groove 11 and the right zipper slide groove 12 are arranged opposite to each other, with a gap between them. In use, the head end of the zipper slide rail is connected to the vibrating plate. When the zipper head enters the zipper slide rail, the pull rope is located within the gap between the left zipper slide groove 11 and the right zipper slide groove 12. The left side of the zipper head slides along the left zipper slide groove 11, and the right side of the zipper head slides along the right zipper slide groove 12. The pull rope passes through the gap between the left zipper slide groove 11 and the right zipper slide groove 12. The pull cord exposed on the front of the swivel head can travel within the hollow channel on the front of the swivel head (the distance between the left swivel head groove 11 and the right swivel head groove 12), and the pull cord exposed on the back of the swivel head can travel within the hollow channel on the back of the swivel head (the distance between the left swivel head groove 11 and the right swivel head groove 12). Therefore, regardless of whether the pull cord is exposed on the front or back of the swivel head, or both the front and back are exposed at the same time, it can smoothly enter the swivel head slide rail. Even if the pull cord rubs against the swivel head slide rail, it will not easily affect the conveying posture of the swivel head, effectively adapting to and reliably conveying the new type of swivel head with a rope-like pull tab.

[0027] To avoid interference between the pull rope and the slide rail mounting base 2, the slide rail mounting base 2 is provided with a pull rope avoidance cavity 22, which is located in the extended space between the left pull head slide groove 11 and the right pull head slide groove 12; when the pull head passes through the slide rail mounting base 2, the pull rope travels in the pull rope avoidance cavity 22.

[0028] like Figure 1-4 As shown, the pull head conveying device includes a pull head slide rail, which includes a left pull head slide groove 11 and a right pull head slide groove 12. The tail ends of the pull head slide groove 11 and the right pull head slide groove 12 are connected to the slide rail mounting base 2. The left pull head slide groove 11 and the right pull head slide groove 12 are arranged opposite to each other, and there is a gap between the left pull head slide groove 11 and the right pull head slide groove 12.

[0029] The upper surface of the slide rail mounting base 2 has a pull head groove 21. A left baffle 31 is provided on the left side of the pull head groove 21, and the left baffle 31 is located at the end of the left pull head groove 11. A right baffle 32 is provided on the right side of the pull head groove 21, and the right baffle 32 is located at the end of the right pull head groove 12. On the side of the right baffle 32, the left baffle 31 has a pull head left guide block 311, which is set according to the shape of the left side of the pull head (e.g., ...). Figure 3 As shown in the figure, on the left side of the baffle 31, the right side of the baffle 32 has a right-side guide block for the pull head (not shown in the figure). The left-side guide block for the pull head is set according to the shape of the right side of the pull head. The left-side guide block 311 limits the left side of the pull head, and the right-side guide block limits the right side of the pull head. The left-side guide block 311 and the right-side guide block for the pull head constitute the pull head positioning groove (pull head release port), and the pull head can be released from above the pull head positioning groove. Of course, the left-side guide block 311 or the right-side guide block for the pull head can also adopt a common guide structure. Of course, the pull head slide groove 21 on the upper surface of the slide rail mounting base 2 can also be formed by the left side baffle 31 and the right side baffle 32. Of course, the pull head release port can also be set on the pull head slide rail, such as the upper surface of the left pull head slide groove and the upper surface of the right pull head slide groove are both provided with notches, and the notches of the left pull head slide groove and the right pull head slide groove constitute the pull head release port; of course, a baffle can also be set at the notch, and similarly, a guide block can also be set on the baffle.

[0030] To further restrain the tail of the slider and limit its position at the slider release point, a stop is provided within the slider groove 21, such as... Figure 3 As shown, the stop is a protrusion 312 on the left side baffle 31, which is located inside the slider groove 21. Alternatively, the right side baffle 32 may also have a protrusion located inside the slider groove 21 to block the right side of the slider. Of course, the stop can also be directly located inside the slider groove 21.

[0031] To facilitate adjustment of the distance between the two side baffles and to facilitate the installation of the baffles, both the left and right side baffles are provided with baffle grooves 231 and 232 and oblong holes. The left and right side baffles can slide along the baffle grooves respectively. Fasteners (bolts, screws or other fasteners) are provided in the oblong holes. When the baffles slide along the baffle grooves, the distance between the left side baffle 31 and the right side baffle 32 can be adjusted. At the same time, the fasteners can be relatively displaced within the oblong holes. After adjustment, the baffles are fixed in the predetermined position by the fasteners.

[0032] To guide the slider head to slide into the slider head groove 21, a left slider head guide groove 111 is provided between the left side baffle 31 and the slide rail mounting base 2 at the front end of the slider head release port. The left slider head guide groove 111 and the left slider head groove 11 are connected. A right slider head guide groove 112 is provided between the right side baffle 32 and the slide rail mounting base 2. The right slider head guide groove 112 and the right slider head groove 12 are connected. Of course, to avoid the pull rope, there is also a gap between the left side baffle 31 and the right side baffle 32. This gap is connected to the gap between the left slider head guide groove 111 and the right slider head groove 12. When the slider head travels through the guide groove, the left side of the slider head slides along the left slider head guide groove 111, and the right side of the slider head slides along the right slider head guide groove 112. The pull rope (if present) on the front of the slider head travels within the gap between the left side baffle 31 and the right side baffle 32.

[0033] To avoid the pull cord on the back of the slider head, the slider mounting base 2 is provided with a pull cord avoidance cavity 22, which is located in the extended space between the left slider head slide groove 11 and the right slider head slide groove 12. When the slider head passes through the slider mounting base 2, the pull cord (if any) on the back of the slider head travels within the pull cord avoidance cavity 22.

[0034] To flexibly limit the slider at the release point, a flexible limiting component is provided. This component is made of soft glass (or rubber sheet, or other flexible material). The flexible limiting component includes a left flexible limiting component 41 and a right flexible limiting component 42. The left flexible limiting component 41 is mounted on the left baffle 31 to limit the left side of the slider, and the right flexible limiting component 42 is mounted on the right baffle 32 to limit the right side of the slider. Alternatively, a flexible limiting component can also be provided on one side of the release point, such as on the left side to limit the left side of the slider, or on the right side to limit the right side of the slider. When the slider detaches from the release point, the flexible limiting component deforms to allow the slider to detach; after detachment, the flexible limiting component returns to its original shape, thus limiting the next slider.

[0035] The pull-out end is equipped with grippers, including a left gripper 51 and a right gripper 52. The grippers are mounted on a gripper power device 61, which is a pneumatic finger that drives the left gripper 51 and the right gripper 52 to complete the gripping action. Of course, the gripper power device 61 can also be other common gripping structures, such as the right gripper 52 being a fixed gripper and the left gripper 51 being a movable gripper. The movable gripper is equipped with a slide rail and a cylinder (or electric cylinder, or other type of power device). The cylinder drives the movable gripper to slide along the slide rail, causing the movable gripper to move closer to the fixed gripper, thereby completing the gripping action. Alternatively, the left gripper 51 and the right gripper 52 can each be equipped with a cylinder, and the two cylinders drive the left gripper 51 and the right gripper 52 to move closer to each other, thereby completing the gripping action.

[0036] The gripper power unit 61 is mounted on the lifting plate 62, which is mounted on the lifting seat 63. The lifting seat 63 is equipped with a lifting power unit 64, which is mounted on the traveling seat 65. The lifting power unit 64 is a cylinder that drives the lifting seat 63 to move up and down on the traveling seat 65, thereby causing the gripper to move up and down. Alternatively, the lifting power unit 64 can be an electric cylinder or other types of power unit. Of course, the gripper power unit 61 can also be directly mounted on the lifting seat 63.

[0037] To guide the movement of the lifting seat 63, the lifting seat 63 is provided with a guide groove 632, within which a guide rail 631 is installed. The guide rail 631 is mounted on the traveling seat 65. When the lifting seat 63 moves on the traveling seat, the guide groove 632 moves up and down along the guide rail 631. Alternatively, the guide rail 631 can also be mounted on the lifting seat 63, and correspondingly, the guide groove 632 can be mounted on the traveling seat 65.

[0038] The travel seat 65 is equipped with a travel power device, which is a rodless cylinder. The rodless cylinder drives the travel seat 65 to move, and the travel seat 65 drives the gripper to move, thereby pushing the pull head to the next process. Of course, the travel power device can also be other common linear motion mechanisms. For example, the travel seat 65 is mounted on the travel slider 71, and the travel slider 71 is equipped with a travel guide rail 72 and a power device (such as a cylinder, electric cylinder, or other common power devices). The power device drives the travel slider 71 to slide along the travel guide rail 72, thereby pushing the pull head to the next process.

[0039] In use, the vibratory feeder sequentially transports the slider head to the slider head slide rail. The slider head slides along the slider head slide rail to the slider head release port. The gripper power device 61 drives the gripper to hold the slider head at the release port. The lifting power device 64 drives the lifting seat 63 to move upward on the traveling seat 65, so that the slider head held by the gripper is released from the slider head release port. The traveling power device drives the traveling seat 65 to move forward, and the traveling seat 65 drives the gripper to move forward, thereby pushing the slider head onto the lower die seat 9 of the slider head, thus completing the slider head insertion action.

[0040] When the pull head is pushed into place, the gripper power device 61 drives the gripper to release the pull head, so that the pull head falls onto the lower die seat 9; or the lifting power device 64 drives the lifting seat 63 to move downward on the traveling seat 65, so that the pull head falls onto the lower die seat 9 and then the pull head is released.

[0041] After the pull head is pushed into place, the lifting power device 64 drives the lifting seat 63 to move upward and reset on the traveling seat 65 (if applicable). The traveling power device drives the traveling seat 65 to move backward and reset, so that the gripper is reset above the pull head release port. The lifting power device 64 drives the lifting seat 63 to move downward and reset on the traveling seat 65, so that the gripper is reset to the pull head release port, and then the next pull head is conveyed.

[0042] The grippers can hold the top plate of the zipper pull, or they can hold the sides of the zipper pull.

[0043] 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.
