Description

TECHNICAL FIELD

[0001] The present application relates to a slider pushing positioning device, belonging to the technical field of slider production equipment. BACKGROUND

[0002] A double-nose slider punching slider disclosed in the patent publication CN106213694A includes a slider body, upper and lower nose heads provided on the slider body, upper and lower pull tabs assembled between the upper and lower nose heads and the upper and lower boat plates, and a support core between the upper and lower boat plates. This type of double-pull-tab slider faces special challenges in automatic production.

[0003] The slider clamping device positions the slider on the zipper conveying path, and the chain belt is pulled through the slider to complete the threading action. The slider clamping device usually includes an upper die set and a lower die set, the lower die set includes a left lower die and a right lower die, and the left lower die and the right lower die have a gap therebetween. The slider is conveyed between the upper die set and the lower die set and positioned on the left lower die and the right lower die. At this time, the mounting surface of the pull tab faces downward, and the pull tab naturally falls into the gap between the left lower die and the right lower die. The lower die set is closed to the upper die set (or the upper die set is closed to the lower die set, or the lower die set and the upper die set are closed at the same time), and finally the slider positioning is completed. For example, the patent publication CN215501599U discloses a slider clamping device.

[0004] However, the above-mentioned conventional slider clamping device is only suitable for the clamping and positioning of single-pull-tab sliders, and the mounting surface (the side with the pull tab) of the pull tab needs to face downward. The pull tab naturally falls between the left lower die and the right lower die by gravity and does not interfere with the clamping and positioning of the slider and the subsequent threading action. When the aforementioned double-pull-tab slider or the pull tab mounting surface faces upward is applied, the upper pull tab lacks fixed support and will lie randomly on the tail of the slider or on the left and right sides of the slider, and is easily displaced by external force (vibration). This unpredictable posture not only interferes with the clamping action of the upper die and the lower die, but also interferes with the completion of the subsequent threading process, which may cause damage to the zipper or even cause the equipment to stop.

[0005] The slider threading and cutting machine needs to advance the clamping jaw to the slider clamping device (or the front end) first to pull the chain belt to complete the threading and cutting of the pull tab. The pull tab lying on the tail of the slider will be located on the clamping jaw path, thus interfering with the clamping jaw, which may cause the clamping jaw to collide with the pull tab and damage the slider, or even cause the clamping jaw to fail to clamp the chain belt.

[0006] On the other hand, the existing zipper head cutting machine is not suitable for automatic head threading of double-pull zipper slider, especially, it cannot effectively push the double-pull zipper slider to the zipper clamping device. SUMMARY

[0007] The purpose of the present application is to provide a zipper slider pushing and positioning device to realize automatic pushing and positioning of double-pull zipper slider and meet the automatic process requirements of double-pull zipper slider.

[0008] In order to achieve the above technical purpose, the technical scheme of the present application is:

[0009] The zipper slider pushing and positioning device comprises a zipper slider clamping device, the zipper slider clamping device comprises a lower mold, the lower mold comprises a lower movable mold and a lower fixed mold, the top of the lower movable mold is provided with a movable zipper slider limiting groove, the top of the lower fixed mold is provided with a fixed zipper slider limiting groove, the lower movable mold is provided with a lower movable mold power device, the lower movable mold power device drives the lower movable mold to approach the lower fixed mold, and the movable zipper slider limiting groove and the fixed zipper slider limiting groove cooperate to limit the zipper slider; the upper mold is arranged above the lower mold, and the upper mold cooperates with the lower fixed mold to clamp the zipper slider.

[0010] One side of the zipper slider clamping device is provided with a zipper slider overturning and pushing device, the zipper slider overturning and pushing device comprises a zipper slider receiving groove with an opening facing upward, the zipper slider receiving groove is rotationally connected to an overturning seat, the zipper slider receiving groove is provided with an overturning power device, the overturning power device drives the zipper slider receiving groove to rotate on the overturning seat, and the overturning seat is provided with a traveling power device.

[0011] The zipper slider receiving groove receives the zipper slider sliding down the zipper slider rail, the overturning power device drives the zipper slider receiving groove to rotate, so that the zipper slider is turned to a flat-lying state, the traveling power device drives the overturning seat to travel, and the flat-lying zipper slider is pushed to the space between the upper mold and the lower mold, the zipper slider is located between the lower fixed mold and the lower movable mold, the lower movable mold power device drives the lower movable mold to approach the lower fixed mold, the movable zipper slider limiting groove and the fixed zipper slider limiting groove cooperate to limit the zipper slider, and the upper mold and the lower mold cooperate to clamp the zipper slider.

[0012] Before the upper mold and the lower mold cooperate to clamp the zipper slider, the traveling power device drives the overturning seat to retreat and reset, so that the zipper slider receiving groove is separated from the clamping area of the upper mold and the lower mold, and interference with the clamping action of the upper mold and the lower mold is avoided; when the overturning seat retreats and resets, the overturning power device drives the zipper slider receiving groove to rotate and reset.

[0013] When the puller head is in the vertical state (or approximately vertical, or inclined vertical) and the head slot opening faces upward, the puller head is in the vertical state (or approximately vertical, or inclined vertical), and the two pull tabs will naturally fall on both sides of the puller head due to gravity; the turning power device drives the puller head slot to turn and turn into a flat state, at this time, the puller head also turns from the vertical state to the flat state, the pull tab below the puller head will naturally fall below the puller head, and the pull tab above the puller head will lie on the puller head slot and face the bottom of the puller head slot; when the puller head slot is driven by the advancing power device to advance between the upper die and the lower die, the pull tab above the puller head will remain in the lying state facing the bottom of the puller head slot, on the side of the lower die. Because the lower pull tab is located between the lower die and the lower fixed die, and the upper pull tab lies on the puller head slot, the upper pull tab will not interfere with the puller head limiting slot and the fixed puller head limiting slot to limit the puller head. Because the upper pull tab lies on the side of the lower die, the upper pull tab will not interfere with the upper die and the lower fixed die to clamp the puller head, so as to achieve the clamping and positioning of the puller head.

[0014] In order to facilitate the control of the turning of the puller head slot and avoid the interference between the puller head slot and the puller head slide rail when the puller head slot turns, the advancing power device has a first stroke and a second stroke, the first stroke makes the puller head slot advance between the puller head slide rail and the puller head clamping device, and the second stroke makes the flat puller head push between the upper die and the lower die.

[0015] In order to position the pull tab on the side of the lower die and avoid its displacement and interference with the clamping jaw at the rear end of the clamping and positioning device, a pull tab limiting part is arranged above the lower die, and the pull tab limiting part is used to limit the pull tab.

[0016] Preferably, the pull tab limiting part is a suction nozzle or a clamping jaw or an electromagnet or other components that can position the pull tab. After the moving puller head limiting slot and the fixed puller head limiting slot cooperate to limit the puller head, the pull tab limiting part limits the pull tab (suction or adhesion or clamping), which realizes the fixation of the upper pull tab and eliminates the influence of the upper pull tab. Of course, when the advancing power device pushes the flat puller head between the upper die and the lower die, the pull tab limiting part can limit the pull tab first.

[0017] In order to realize the lifting of the pull tab limiting part, the pull tab limiting part is provided with a limiting part lifting power device, and the limiting part lifting power device is used to drive the pull tab limiting part to lift.

[0018] In order to realize the clamping action of the upper die and the lower die, the lower die is provided with a lower die power device, and the lower die power device is used to drive the lower die to close to the upper die, so that the lower fixed die and the upper die cooperate to clamp the puller head.

[0019] In order to limit the lying posture of the pull tab on the pull head groove, avoid the displacement of the pull tab on the pull head groove, and separate the pull tab from the working area of the pull tab limiting part, a limiting block is arranged on each side of the pull head groove. Of course, the distance between the two limiting blocks should be greater than the width of the pull tab, so that the pull tab can fall between the two limiting blocks.

[0020] In order to avoid the interference of the pull head with the driving of the pull head groove, the pull head groove is composed of a movable block and a fixed block, the tail of the movable block is rotatably connected to the fixed block, and an elastic component (tension spring) is arranged between the movable block and the fixed block. The elastic component is used to make the head of the movable block rotate towards the fixed block to reset the pull head groove. When the driving device drives the pull head groove to retreat (the pull head is limited and fixed by the upper die and the lower die, or is limited and fixed by the movable pull head limiting groove and the fixed pull head limiting groove), the pull head blocks the movable block, and the head of the movable block rotates away from the fixed block to avoid the pull head, so that the movable block can be separated from between the upper die and the lower die. After the movable block is separated from the pull head, the elastic component makes the head of the movable block rotate towards the fixed plate to reset the pull head groove.

[0021] An active block guide and a fixed block guide are arranged in the pull head groove, the active block guide is arranged on the movable block, the fixed block guide is arranged on the fixed block, and the active block guide and the fixed block guide have a distance therebetween. The active block guide and the fixed block guide are used to extend into between the upper and lower boat plates of the pull head, and the distance between the active block guide and the fixed block guide is used for the pull head core to pass through.

[0022] The pull head sliding rail is provided with a pull head blocking component and a pull head pushing component. The pull head pushing component pushes the pull head to slide along the pull head sliding rail, and pushes the pull head to slide through the pull head blocking component and fall into the pull head groove.

[0023] The pull head clamping device provided by the application can actively fix the pull tab above the pull head by adding a pull tab limiting part (such as a suction nozzle, a clamping jaw or an electromagnet) on one side of the upper die, thereby solving the problem of uncontrollable posture of the pull tab of the double-pull-tab pull head or the pull tab installed with the upper surface. Specifically, the pull tab limiting part can fix the pull tab before clamping or during clamping, prevent the pull tab from lying randomly on the tail or both sides of the pull head, avoid interference with the closing action of the upper die and the lower die, and ensure the stability of clamping positioning. By fixing the pull tab above, the pull tab is prevented from hanging in the clamping jaw path and interfering with the clamping jaw diameter, preventing equipment downtime or chain damage caused by clamping jaw collision with the pull tab, and significantly improving the reliability of the threading process.

[0024] The pull head pushing positioning device provided by the application is suitable for the process requirements of the double-pull-tab pull head or the pull tab installed with the upper surface, reduces manual intervention and equipment failure rate, and improves the continuous operation efficiency of the threading cutting machine. Specifically,

[0025] (1) The puller is slid into the upward-opening puller receiving groove in an upright state, and the turning power device drives the puller receiving groove to turn to a flat-lying state, so that the lower pull tab naturally falls and the upper pull tab stably lies on the groove bottom direction, avoiding the loss of control of the pull tab posture during the pushing process.

[0026] (2) When the advancing power device pushes the turning seat to move the puller to the clamping station, the pull tab limiting part can fix the upper pull tab on the lower movable die side, avoiding its drooping at the tail of the puller to interfere with the advancing path of the clamping jaw, preventing the equipment shutdown or chain damage caused by the collision of the clamping jaw with the pull tab, and significantly improving the reliability of the puller threading process; when the turning seat retreats and resets after the pushing is completed, the elastic reset design of the movable block and the fixed block enables the puller receiving groove to automatically avoid the fixed puller when retreating, avoiding structural collision.

[0027] (3) The movable block guide and the fixed block guide extend into the gap between the puller deck, ensuring the passability of the machine core while providing precise guidance. BRIEF DESCRIPTION OF DRAWINGS

Of course, the traveling power device can also be an electric cylinder (or other power device of the same type) capable of providing multi-stroke control, so as to provide more accurate control. Of course, the traveling power device can also have more than two strokes to provide more than two displacements.

[0047] Of course, in order to improve the stability of the movement of the traveling block 35, the traveling block 35 can be provided with a guide mechanism, specifically, the traveling block 35 is matched with a traveling block guide rail 351, and the traveling power device drives the traveling block 35 to slide along the traveling block guide rail 351.

[0048] As shown in Figure 6 The puller groove 31 is composed of a movable block 311 and a fixed block 312, the tail of the movable block 311 is rotatably connected to the fixed block 312 through a rotating shaft 312, and the rotation of the movable block 311 in the fixed block 312 makes the head of the movable block 311 away from the fixed block 312. Of course, the movable block 311 can also be rotatably connected to the fixed block 312 through other common rotating connection modes.

[0049] An elastic component 314 is provided between the movable block 311 and the fixed block 312. The elastic component 314 is a tension spring (or other common elastic components, such as a rubber band). The elastic component 314 is used to make the movable block 311 rotate on the fixed block 312, so that the head end of the movable block 311 moves closer to the fixed block 312 and resets the pull head bearing groove 31. Specifically, a first limiting post is provided on the movable block 311, and a second limiting post is provided on the fixed block 312. One end of the tension spring is connected to the first limiting post, and the other end of the tension spring is connected to the second limiting post. When the movable block 311 is subjected to force and rotates on the fixed block 312, the head of the movable block 311 moves away from the fixed block 312, and the tension spring deforms under force. After the movable block 311 is freed from the external force, the tension spring returns to its original shape, so that the movable block 311 is subjected to force and rotates on the fixed block 312, and the head end of the movable block 311 moves closer to the fixed block 312 and resets the pull head bearing groove 31.

There is a gap between the movable guide plate 315 and the fixed guide plate 316. When the slider slides into the slider receiving groove 31, the movable guide plate 315 and the fixed guide plate 316 extend between the upper and lower plates of the slider. The slider mechanism is located within the gap between the movable guide plate 315 and the fixed guide plate 316. The movable guide plate 315 and the fixed guide plate 316 are located on both sides of the slider mechanism to support the slider sliding down the slider rail. Of course, the gap between the movable guide plate 315 and the fixed guide plate 316 can also be set only at the top of the slider receiving groove 31, such as... Figure 6 As shown, the fixed block guide plate 316 has a specific notch, and the movable block guide plate 315 and the notch form the distance for accommodating the mechanism; of course, the notch can also be set on the movable block guide plate 315, and the fixed block guide plate 316 and the notch form the distance for accommodating the mechanism. Of course, the slider receiving groove 31 can adopt other common slider receiving groove forms. For example, the movable block 311 is provided with a movable block slider groove, and the fixed block 312 is provided with a fixed block groove. The movable block slider groove and the fixed block groove are arranged opposite to each other, and the left and right sides of the slider are respectively located in the two slider grooves to receive the slider sliding down the slider rail.

[0051] In order to limit the lying posture of the upper pull tab (the pull tab lying on the puller groove 31 when the puller groove 31 is turned to a flat lying state) on the puller groove, avoid the upper pull tab swinging displacement on the puller groove when the puller groove 31 moves, and avoid the upper pull tab from the working area of the pull tab limiting part 28, a limiting block is arranged on both sides of the puller groove 31. Specifically, the limiting parts on both sides can be composed of the first limiting column and the second limiting column as described above. The first limiting column and the second limiting column are located on the front side of the puller groove 31 (when the puller groove 31 is turned to a flat lying state, the two limiting columns are turned to an upright state and located above the puller groove 31), and are located on both sides of the puller groove 31. When the puller falls into the puller groove 31, the upper pull tab falls between the first limiting column and the second limiting column. The first limiting column and the second limiting column limit the left and right of the upper pull tab to avoid swinging under stress. Of course, the limiting blocks arranged on both sides of the puller groove 31 can also be arranged separately, or composed of other parts on the front side of the puller groove 31. Of course, the distance between the two limiting blocks should be greater than the width of the front pull tab, so that the pull tab can fall between the two limiting blocks.

[0052] As shown in Figures 7-9 The puller slide rail 4 includes a left slide rail plate 41 and a right slide rail plate 42. The left slide rail plate 41 is provided with a left slide rail piece 43, and the right slide rail plate 42 is provided with a right slide rail piece 44. The left slide rail piece 43 and the right slide rail piece 44 have a space therebetween for the puller movement. When the puller is located in the puller slide rail 4, the left slide rail piece 43 and the right slide rail piece 44 are used to extend between the upper and lower boat plates of the puller. The puller movement is located in the space between the left slide rail piece 43 and the right slide rail piece 44, and the left slide rail piece 43 and the right slide rail piece 44 are located on both sides of the puller movement, respectively.

[0053] The puller slide rail 4 is provided with a puller blocking part. The puller blocking part includes a limiting pin 45, the limiting pin 45 is provided with a limiting pin sliding hole, the limiting pin 45 reciprocally slides along the limiting pin sliding hole, the limiting pin 45 is provided with a spring (or other common elastic part), the spring is located at the tail end of the limiting pin 45, the head end of the limiting pin 45 extends out of the limiting pin sliding hole, so as to block the puller in the puller slide rail 4, and avoid the puller from leaving the puller slide rail 4 when unnecessary. Preferably, the head end of the limiting pin 45 specifically extrudes a slope. When the puller extrudes the extrusion slope of the head end of the limiting pin 45, the limiting pin 45 reciprocally slides along the limiting pin sliding hole and retracts into the limiting pin sliding hole to give way to the puller, and the spring deforms to give way; when the limiting pin 45 is free from the extrusion force of the puller, the spring restores to the original state, so that the head end of the limiting pin 45 extends out of the limiting pin sliding hole, and then limits the next puller.

[0054] The pusher is arranged on the slider 4, and the pusher comprises a pusher clamping plate 61 in the slider 4, the pusher clamping plate 61 is connected to one side of a pusher rod 62, the pusher rod 62 is rotatably connected to a pusher mounting plate 63 through a pusher rod rotating shaft 621, the pusher rod 62 is provided with a cylinder 64 (or other common linear motion mechanism), the cylinder 64 drives the pusher rod 62 to rotate on the pusher mounting plate 63, so that the pusher clamping plate 61 is separated from / inserted into the slider 4. The pusher mounting plate 63 is provided with a pusher mounting plate sliding rail 631 and a cylinder 65 (or other common linear motion mechanism), the cylinder 65 drives the pusher mounting plate 63 to slide along the pusher mounting plate sliding rail 631, so that the pusher clamping plate 61 walks in the slider 4.

[0055] The cylinder 65 drives the pusher mounting plate 63 to slide along the pusher mounting plate sliding rail 631, the pusher clamping plate 61 pushes the slider 4 in the slider 4, so that the slider 4 passes through the limiting pin 45, and then the slider 4 slides along the slider 4. After the slider falls, the cylinder 64 drives the pusher rod 62 to rotate on the pusher mounting plate 63, so that the pusher clamping plate 61 is separated from the slider 4, and the next slider is avoided, so that the push needle can retreat and reset, then the cylinder 65 drives the pusher mounting plate 63 to slide along the pusher mounting plate sliding rail 631 and reset, after the pusher mounting plate sliding rail 631 is reset, the cylinder 64 drives the pusher rod 62 to rotate on the pusher mounting plate 63, so that the pusher clamping plate 61 is inserted into the slider 4 again and located above the slider to be pushed.

[0056] In use, the slider groove 31 receives the slider falling from the slider 4, the first stroke power device 36 drives the turnover seat 33 to move, and pushes the slider groove 31 to the position between the slider 4 and the slider clamping device 2; the turnover power device 34 drives the slider groove 31 to rotate, so that the slider groove 31 is in a flat state, at this time, the slider is also in a flat state; the second stroke power device 38 drives the turnover seat 33 to continue to move, and pushes the flat slider to the position between the upper die and the lower die, the slider is located between the lower fixed die 21 and the lower movable die 22, the lower movable die power device 223 drives the lower movable die 22 to move close to the lower fixed die 21, the movable slider limiting groove 212 and the fixed slider limiting groove 211 cooperate to limit the slider; the second stroke power device 38 drives the turnover seat 33 to retreat and reset, the slider blocks the movable block 311, the head of the movable block 311 rotates away from the fixed block 314 to avoid the slider, so that the movable block 311 can pass through the slider, after the movable block 311 is separated from the slider, the elastic component 314 makes the head of the movable block 311 rotate to the side of the fixed block 316, and the slider groove 31 is reset. Subsequently, the turnover power device 34 drives the slider groove 31 to rotate and reset, the first stroke power device 36 drives the turnover seat 33 to retreat and reset, and the slider groove 31 is reset to the tail end of the slider 4.

[0057] Of course, the second stroke power device 38 can also drive the turnover seat 33 to move first, pushing the puller groove 31 to the puller slide rail 4 and the puller clamping device 2, and then the first stroke power device 36 continues to drive the turnover seat 33 to move, pushing the puller to the upper die and the lower die.

[0058] Of course, the puller groove 31 can also be turned over when it is separated from the puller slide rail 4, or it can be turned over in the second pushing process (when the second stroke power device 38 or the first stroke power device 36 pushes), or it can be turned over when it is at the end of the puller slide rail 4. Of course, in order to solve the interference problem between the puller groove 31 and the puller slide rail 4, a clearance can be reserved between the puller groove 31 and the puller slide rail 4, or a matching mode that does not interfere can be used. At this time, the moving power device can only have one stroke to directly push the puller to the puller clamping device 2. Of course, the moving power device can also only have one stroke, and the puller groove 31 turns over during the movement from the end of the puller slide rail 4 to the puller clamping device 2. After the puller groove 31 is separated from between the upper die and the lower die, the lower die power device 25 drives the lower die to move towards the upper die 27, and the lower fixed die 21 and the upper die 27 cooperate to clamp the puller, achieving the positioning of the puller and then completing the subsequent threading process.

[0059] When the puller is pushed to between the upper die and the lower die, or the movable puller limiting groove 212 and the fixed puller limiting groove 211 cooperate to limit the puller, the pull tab limiting member 28 adsorbs the upper pull tab. Of course, the limiting member lifting power device 281 can drive the pull tab limiting member 28 to move upwards, causing the pull tab limiting member 28 to move the upper pull tab upwards. Of course, the limiting member lifting power device 281 can also drive the pull tab limiting member 28 to move downwards first, and then adsorb the pull tab.

[0060] Because the opening of the puller groove 31 is upward, when the puller slides into the puller groove 31 in a vertical state (or approximately vertical, or inclined vertical), the puller is in a vertical state (or approximately vertical, or inclined vertical), and the two pull tabs will naturally fall on both sides of the puller due to gravity. The turnover power device 34 drives the puller groove 31 to rotate, turning the puller groove 31 to a horizontal state. At this time, the puller also changes from a vertical state to a horizontal state, and the pull tab below the puller will naturally fall below the puller, and the pull tab above the puller will lie on the puller groove 31 and face the direction of the bottom of the puller groove 31. When the moving power device drives the puller groove to move between the upper die and the lower die, the pull tab above the puller will remain in a lying state facing the bottom of the puller groove, on the side of the lower movable die 22. Because the lower pull tab is between the lower movable die 22 and the lower fixed die 21, and the upper pull tab lies on the puller groove 31, the upper pull tab will not interfere with the movable puller limiting groove and the fixed puller limiting groove limiting the puller. Also, because the upper pull tab lies on the side of the lower movable die, the upper pull tab will not interfere with the upper die and the lower fixed die clamping the puller, achieving the clamping and positioning of the double-pull-tab puller.

[0061] The above embodiments do not limit the present application in any way, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present application.
