Description

Technical Field

[0001] The present invention relates to an assembly machine, in particular to a fully automatic assembly machine for production clips. Background Art

[0002] The current manufacturing process of clip-type anchors is to saw the material into the required product size; the first step is to forge the target workpiece to make it hard and strong; the second step is to turn the workpiece to a certain taper, and punch text marks on the bottom and sides of the workpiece, and tap the inside of the target workpiece. This step is to ensure that the workpiece and the steel strand fit together; sawing, saw a groove on the outer surface of the clip, the size of the groove is similar to the inner diameter of the O-ring, the purpose is to combine the two clips into a whole through the O-ring, and after the ring is completed, the clip pair is quality inspected and put into storage.

[0003] At present, the clamping manufacturers mainly adopt manual clamping, which is a traditional manufacturing process with low production efficiency and high cost.

[0004] Major companies are beginning to transition to fully automated production lines, and they need to overcome the obstacles to fully automated production technology and conduct research and development. Most companies processing clips still use the traditional manual ring-making method. Although this method has good quality, its production efficiency is very low and does not meet the needs of high-efficiency production. Prolonged work in this environment can cause fatigue, and if there is mechanical equipment in operation nearby, there will be a significant safety hazard. If a safety accident occurs, the benefits will outweigh the costs.

[0005] Currently, there is a huge demand for clips. Many companies use manual ring-feeding to assemble clips, resulting in very low production. This method has low production efficiency and has led to a shortage of clips. If the problem of fully automatic ring-feeding and loading can be solved, it means that the equipment can perform uninterrupted processing, greatly shortening the product production cycle, improving efficiency and thus increasing production. Manual O-ring fitting and semi-automatic ring-feeding and loading methods have not kept up with the current development trend of high-efficiency, high-quality, and high-profit production and manufacturing. Therefore, the development of a fully automatic clip assembly machine can effectively solve the problems of manual ring-feeding and manual loading, thereby improving product quality, increasing production efficiency, reducing manufacturing costs, and gaining greater profit margins for enterprises. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a fully automatic assembly machine for production clips.

[0007] The technical solution to the above technical problem is: a fully automatic assembly machine for production clips, including a transplanting mechanism, an O-ring vibration plate, a ring mechanism, a control system and a feeding mechanism. The number of the feeding mechanisms is two, and the two feeding mechanisms are respectively connected to the transplanting mechanism through a herringbone channel and a feeding pipe. The clips are fed into the transplanting mechanism by the feeding mechanism, and the two semicircular clips are relatively combined into a circular clip by the transplanting mechanism. The O-ring vibration plate feeds the O-ring to the ring mechanism, and the ring mechanism puts the O-ring on the circular clip formed by the transplanting mechanism, thereby completing the automatic feeding and ringing of the clips.

[0008] The feeding mechanism includes a storage device, a pushing device and a transmission device. The transmission device includes a material channel, a direction-reversing device, a direction-flipping device and a biasing device. The material channel is connected to the straight vibrating machine. The clamps on the material channel are transmitted by the vibration of the straight vibrating machine. The direction-reversing device, the direction-flipping device and the biasing device are sequentially arranged on the material channel. The direction-reversing device, the direction-flipping device and the biasing device are used to reverse, flip and bias the clamps being transmitted in turn, so that the two semicircular clamps form a side-standing state with the arc surface facing outward and the concave surfaces facing each other for unloading.

[0009] The herringbone channel is formed by connecting two channels at one end. The material channels of the two feeding mechanisms are connected to the feeding pipe through the herringbone channel. The two semicircular clips approach and merge through the herringbone channel and enter the feeding pipe.

[0010] A further technical solution of the present invention is as follows: the material storage device includes a hopper, and the material channels include channel I, channel II, channel III, and channel IV; a clip is placed in the hopper, and an O-ring is placed in an O-ring vibrating plate; a control system is used to activate the clip feeding mechanism and the O-ring vibrating plate to operate simultaneously;

[0011] The clips are advanced upward in the hopper by the push plate that moves up and down to reach the material channel; the clips fall into material channel I and move forward under the action of the straight vibrator; the clips conveyed to material channel II are all in a tilted state, and through the direction reversing device on material channel II, the clips conveyed to material channel III are all in a state with the large end facing forward; through the direction flipping device on material channel III, the clips conveyed to material channel IV are all in a state with the semicircular opening facing upward; when the clips reach material channel IV, all of them are in a state with the large diameter end facing forward and the semicircular opening end facing upward; the offset device on material channel IV offsets the clips so that the sawing surface of the clips is perpendicular to the bottom plate of the feed channel, and the clips reach the feeding pipe under the continuous vibration of the straight vibrator;

[0012] The clip falls through the feeding pipe to the switch sensor position of the feeding pipe of the transfer mechanism. When the switch sensor senses that the clip has fallen to this position, it will output an electrical signal, causing the mini cylinder to make a telescopic movement command. The clamping plate is connected to the mini cylinder. Through the telescopic movement of the clamping plate, the clip on the clamping plate is controlled to fall into the slot of the dividing block. The dividing block then drops the clip into the slot of the transfer main board. The transfer main board moves the clip forward to the position for installing the O-ring, and the clamp is ringed by the ring mechanism.

[0013] Through the vibration of the O-ring vibration plate, the O-rings in the O-ring vibration plate follow the two feeding tracks to the O-ring loading plate. The O-ring loading plate is equipped with an electro-optical sensor. The electro-optical sensor senses the presence of O-rings on the O-ring loading plate and transmits a signal. The cylinder controls the air claw to fall and grab the O-ring, and then moves the O-ring to the clamping piece where the ring is required for ring insertion.

[0014] The storage device includes a hopper, and the pushing device includes a pushing plate. The upper end surface of the pushing plate is an inclined surface. The pushing plate includes a fixed plate and a pushing plate. The fixed plate is fixedly set on the bracket. The pushing plate is connected to the cylinder and is set in front of the fixed plate. The clip in the hopper is pushed into the material channel of the transmission device.

[0015] The pushing plate includes pushing plate I and pushing plate II. Pushing plate I is located at the lower end of pushing plate II, and the hopper is located at the lower end of pushing plate I. Pushing plate I includes fixed plate I and pushing plate I. Pushing plate II includes fixed plate II and pushing plate II. Pushing plate I pushes the clip at the hopper to fixed plate I, and pushing plate II pushes the clip at fixed plate I to the top of fixed plate II and drops it to the transmission device.

[0016] The reversing device includes an arc-shaped slide, a reversing baffle and a block. The block is fixed on the material channel II. The distance between the block and the upper end of the arc-shaped slide forms a reversing entrance. One end of the reversing baffle is fixed on the block, and the reversing baffle is located in the reversing entrance. The distance between the reversing baffle and the arc-shaped slide is half the height of the clip. The clip enters the reversing entrance and slides from the material channel II to the material channel III through the arc-shaped slide.

[0017] Method of changing direction: Since the clip is a semicircular structure with one end larger than the other, with half the height of the clip as the dividing line, the center of gravity of the clip deviates from the dividing line and deviates toward the large end; when the small end of the clip faces forward, the center of gravity is located behind the dividing line, and the clip will exceed the dividing line when moving to the turning entrance. At this time, the small end of the clip will continue to move forward to the turning block, and the turning block will block the falling of the small end. At this time, the large end of the clip with the center of gravity toward the large end will fall into the turning entrance first and slide through the arc slide. At this time, the clip changes direction so that the large end faces forward.

[0018] The flipping direction device includes a transition channel and an L-shaped plate. The L-shaped plate is arranged at the upper end of the transition channel. The distance between the L-shaped plate and the side wall of the transition channel forms a flipping entrance. The distance between the L-shaped plate and the side wall of the transition channel is the radius of the clip. When the clip on channel III is conveyed and falls into channel IV, the clip moves to the L-shaped plate and flips through the flipping entrance.

[0019] Flip direction method: Since the clip is an arc-shaped semicircular structure, the center of gravity of the clip is located at the arc convex outward. When the clip on the material channel III is arc-faced upward, the center of gravity of the clip is located at the top. When the clip passes through the flip entrance, the clip falls sideways. Under the action of its own gravity, the clip flips during the falling process to form an arc-faced downward fall. At this time, the clip that falls on the transition material channel flips to become an arc-faced downward state.

[0020] The biasing device includes a rounded corner reversing block, which is a wedge-shaped structure. The edge of one side of the upper end of the rounded corner reversing block is an arc-shaped chamfered structure. The rounded corner reversing block is arranged on the material channel IV and forms a bias channel with the side wall of the material channel IV. The distance between the rounded corner reversing block and the side wall of the material channel IV is the radius of the clip, and the distance is the bias channel. When the clip enters the bias channel, the arc surface of the clip contacts the rounded corner of the bias channel and stands sideways along the rounded corner offset.

[0021] Due to the adoption of the above technical solution, the fully automatic assembly machine for production clips of the present invention has the following beneficial effects:

[0022] The present invention adds an automatic clip loading device to the existing clip and collar device, connecting the clip automatic device and the collar device to form a production line. This allows the clip production process, from loading to collaring, to be completed by automated equipment, requiring only individual personnel for patrol and monitoring, significantly reducing work costs and improving work efficiency. The present invention can integrate loading and clip collaring, while maintaining a simple and easy-to-control mechanism while ensuring stability, reliability, durability, and high efficiency. This will promote the improvement of enterprise economic benefits and meet market demand.

DETAILED DESCRIPTION

[0036] A fully automatic assembly machine for production clips includes a transplanting mechanism, an O-ring vibration plate, a ring mechanism, a control system, and a feeding mechanism. The feeding mechanism comprises two groups, which are respectively connected to the transplanting mechanism via a herringbone channel and a feeding pipe. The clips are fed into the transplanting mechanism by the feeding mechanism, and the two semicircular clips are relatively combined into a circular clip by the transplanting mechanism. The O-ring vibration plate feeds the O-ring to the ring mechanism, and the ring mechanism puts the O-ring on the circular clip formed by the transplanting mechanism, thereby completing the automatic feeding and ringing of the clips. The feeding mechanism includes a storage device, a pushing device, and a transmission device. The transmission device includes a material channel, a direction-reversing device, a direction-flipping device, and a biasing device. The material channel is connected to a linear vibrator, and the vibration of the linear vibrator transports the clips on the material channel. The direction-reversing device, the direction-flipping device, and the biasing device are sequentially arranged on the material channel. The direction-reversing device, the direction-flipping device, and the biasing device sequentially reverse, flip, and bias the clips being transported, so that the two semicircular clips are formed into a side-standing state with the arc surface facing outward and the concave surfaces facing each other for unloading. The herringbone channel is formed by connecting two channels at one end. The material channels of the two sets of feeding mechanisms are connected to the feeding pipe through the herringbone channel. The two semicircular clips approach and merge through the herringbone channel and enter the feeding pipe.

[0037] The pusher mechanism loads and transfers the clips, each consisting of half a clip. The two pushers load the clips together and transfer them to the clip mounting device. The two pushers are arranged side by side, and the offset devices are symmetrical, offsetting the two clips into opposing positions, with their planes facing each other. The two clips are fed into the loading tube through a manifold, where they are unloaded. The clip mounting device then assembles the two opposing semicircular clips into a single, circular clip.

[0038] Automatic assembly method of clips:

[0039] Put the clips into the hopper and the O-rings into the O-ring vibrating plate; start the clip feeding mechanism and the O-ring vibrating plate to work simultaneously through the control system; the clips are advanced upward layer by layer in the hopper through the push plate that moves up and down until they reach the material channel; the clips fall into the material channel I (the first material channel) and move forward under the action of the straight vibrator; the clips sent to the material channel II are in a tilted state, and through the direction-reversing device on the material channel II, the clips sent to the material channel III are in a state with their big ends facing forward; the clips are in the straight vibrator Under the action of , it continues to move forward, and then passes through the flip direction device on the material channel III, and the clips transmitted to the material channel IV are all in the state of semicircular opening facing upward. After being transmitted by the material channel, the clips on the material channel III all have the large diameter end face (big head) facing forward and the semicircular opening end face facing upward when they reach the material channel IV; through the biasing device on the material channel IV, the clip is offset so that the sawing surface of the clip (the plane on the semicircular opening end) is perpendicular to the bottom plate of the feeding channel, and the clip reaches the loading pipe under the continuous vibration of the straight vibration machine.

[0040] The clip falls through the feeding pipe to the switch sensor position of the feeding pipe of the transplanting mechanism. When the switch sensor senses that the clip has fallen to this position, it will output an electrical signal, causing the mini cylinder to make a telescopic movement command. The clamping plate is connected to the mini cylinder. Through the telescopic movement of the clamping plate, the clip falling on the clamping plate is controlled to fall into the slot of the dividing block, and then the clip is dropped into the slot of the transplanting main board through the dividing block. The clip is moved forward to the position for installing the O-ring through the transplanting main board, and the clip is ringed through the ring mechanism.

[0041] Specifically, the clips fall into the discharge tube of the transplanting mechanism through the feeding tube. When the first switch sensor detects that there is a clip on the left and right sides of the first clamping plate, the clamping plate is controlled by the first mini cylinder to perform a telescopic movement, and the clips fall down along the discharge tube to the second clamping plate. Similarly, after the switch sensor detects that there are clips on both the left and right sides of the second clamping plate, the second clamping plate performs a telescopic movement, and the clips fall into the slots of the dividing block. Through the action of the two clamping plates, the two groups of clips that continuously enter the discharge tube from front and back are effectively separated. After the first group of clips passes through the second clamping plate, they fall into the right slot of the dividing block below. The double-axis cylinder extends to drive the dividing block to move the clips to the right. When the double-axis cylinder is fully extended, the clips reach the right end and fall into the right slot of the transplanting main board through the leakage slot. When the cylinder is fully extended, the first set of clips reaches the far right end, and the second set of clips also falls into the left slot of the distributor block. After completing the action, the cylinder carries the distributor block to the left for a return motion. After the return is completed, the second set of clips enters the left slot of the transfer main plate. The distributor mechanism operates in a cycle according to this process, continuously providing clips to the left and right slots of the transfer mechanism.

[0042] O-rings are continuously supplied through the operation of the O-ring vibrating plate, which starts working synchronously with the clip feeding mechanism. Under the action of continuous vibration, the O-rings in the O-ring vibrating plate continuously follow the two feeding tracks to the O-ring feeding plate. The O-ring feeding plate is equipped with an electro-optical sensor. The electro-optical sensor senses the presence of O-rings on the O-ring feeding plate and transmits a signal. The cylinder controls the air gripper to drop and grab the O-ring, and then move the O-ring to the clip where the ring is required for insertion.

[0043] Specifically, an electro-optical sensor mounted on the O-ring loading plate determines the presence of an O-ring. Once the sensor detects the presence of an O-ring at both stations, two air grippers, driven by a three-axis cylinder, move toward the two stations. The grippers pass through the O-rings and quickly open, retracting upward. At this point, the grippers, having returned to their original positions, have successfully secured the O-rings. After the jaws reach the third station (the ring-fed station), the jaws align with the grippers, and the grippers move downward, aligning the O-rings on the grippers with the grooves on the jaws. The pusher plate on the grippers then moves downward, releasing the O-rings from the grippers and allowing them to fall into the grooves on the jaws, completing the process. The cylinder retracts, returning the grippers to their original positions, and the next set of O-rings arriving at the loading station begins to be placed.

[0044] After being sorted by the dividing block, the clips enter the transfer mechanism, which is driven by a reciprocating cylinder at its lower end. The transfer mechanism is designed with four stations. The first set of clips enters the transfer main plate and is located at the first station of the transfer mechanism. The transfer main plate is driven forward by the cylinder, and the clips reach the second station. The transfer main plate is then expanded left and right by the cylinder at its lower end. After the expansion is complete, the cylinder retracts and returns to its original position. After returning to the first station, the transfer main plate retracts left and right, returning the first station to its receiving position. The second set of clips in the dividing mechanism enters the transfer main plate and is located at the first station of the transfer mechanism. The above process repeats. As the second set of clips moves to the second station, the first set of clips simultaneously advances to the third station, where the ringing is performed, where the pneumatic gripper completes the ringing. Clips that have successfully ringed are then driven by the movement of the transfer main plate and enter the fourth station, where they are connected to the discharge pipe for the final discharge.

[0045] This invention develops a feeding mechanism for automatically loading clips based on existing systems, including a transfer mechanism, an O-ring vibrating plate, a ring mechanism, and a control system. The O-ring vibrating plate is already available, while the transfer mechanism and ring mechanism are previously developed by the collaborative team. Our university and industry have collaborated on the development of clip assembly devices for many years, including publications such as CN113305526A and CN216829553U. This invention improves upon these previous clip and ring systems.

[0046] The transplanting mechanism includes a feeding pipe, a clamping plate, a dividing block and a transplanting main board. The dividing block is provided with a dividing slot, and the transplanting main board is provided with a transplanting slot. The feeding pipe is located above the dividing block, and the clamping plates are respectively arranged in the feeding pipe. The clamping plates, the dividing block and the transplanting main board are respectively connected to the corresponding cylinders. The clip falls into the feeding pipe through the feeding pipe and falls onto the clamping plate. The clip is adjusted by the clamping plate, and the clip continues to fall into the feeding slot. The clip is then dropped into the transplanting slot by the movement of the dividing block, and the clip is moved to the ring position and the discharge position by the movement of the transplanting main board.

[0047] The ring mechanism includes an air gripper, a push ring plate and an O-ring placement plate. The O-ring placement plate is provided with an O-ring placement groove. The air gripper is movably arranged on the bracket through a cylinder. The push ring plate is connected to the push ring plate cylinder. The push ring plate is provided with an air gripper grommet. The air gripper grommet on the push ring plate is covered on the air gripper and can move up and down along the air gripper. The O-ring grabbed by the air gripper is pushed down by the push ring plate and covered on the clip to complete the ring of the clip.

[0048] Specific embodiment of the feeding mechanism:

[0049] The loading mechanism includes a storage device, a pushing device, and a transmission device. The storage device, the pushing device, and the transmission device are respectively arranged on a bracket. The clip is placed on the storage device, and the clip is loaded onto the transmission device through the pushing device. The storage device includes a hopper, the pushing device includes a pushing plate, and the transmission device includes a material channel. The pushing plate and the hopper are respectively installed in an inclined state, and the upper end surface of the pushing plate is an inclined surface. The pushing plate includes a pushing plate I and a pushing plate II. Pushing plate I is located at the lower end of pushing plate II, and the hopper is located at the lower end of pushing plate I. Pushing plate I pushes the hopper near pushing plate I onto pushing plate II, and pushing plate II pushes the clip onto the transmission device. The material channel is provided with a direction-reversing device, a flipping direction device, and a biasing device. The direction-reversing device, the flipping direction device, and the biasing device are used to sequentially reverse, flip, and bias the clip being transmitted.

[0050] The pusher plate consists of a fixed plate and a pusher plate. The fixed plate is fixed to the bracket, and the pusher plate is connected to the cylinder and installed in front of the fixed plate. Pusher plate I consists of fixed plate I and pusher plate I, while pusher plate II consists of fixed plate II and pusher plate II. Pusher plate I pushes the clip at the hopper to fixed plate I, while pusher plate II pushes the clip at fixed plate I above fixed plate II and drops it to the conveyor. The top end of fixed plate II at the top of the pusher plate is a pointed surface to facilitate the clip's drop. The upper end surfaces of the remaining pusher plates are inclined surfaces. The thickness of the pusher plate is equal to the radius of the clip. Pushing method: Push plate I moves down to or below the hopper. Due to its tilted state and the up-and-down movement of the push plate, the clip slides onto push plate I. When push plate I moves up to fixed plate I, the upper end surfaces of push plate I and fixed plate I form a slope that slopes downward (inward) toward fixed plate I. The clip on push plate I now slides onto fixed plate I. When push plate II moves down to fixed plate I, the upper end surfaces of fixed plate I and push plate II form a slope that slopes downward (inward) toward push plate II. The clip on fixed plate I now slides onto push plate II. Push plate II moves up, pushing the clip upward and onto the conveyor. The upper end surface of the push plate is inclined downward by 20°-30°, with a slope of 25° in this embodiment. This inclined surface of the push plate facilitates the stacking of clips and facilitates the diagonal pouring of clips into the material channel.

[0051] The material channel is connected to the straight vibrating machine, and the vibration of the straight vibrating machine transfers the clips on the channel. The material channels include channel I, channel II, channel III, and channel IV. The push plate pushes the clips onto channel I. The clips that fall from the push plate onto channel I are in an upright state or a tilted state. Channel II is located below the discharge port of channel I, and a step-like height difference is formed between channels I and II. The upright clips on channel I are tilted into a horizontal state when they are transferred to channel II, so that the clips transferred to channel II are all in a tilted state and continue to be transferred forward. The clips on channel II have two states: one with the large end facing forward and the other with the small end facing forward (the conveying direction is forward, which is the front). Channel II is equipped with a reversing device. When the small end of the clip on channel II is facing forward, the reversing device allows the clips on channel II to be transferred to channel III, where they are reversed so that the large end faces forward, so that all the clips on channel III are in the large end facing forward state and continue to be transferred forward. The clips on channel III have two states: one with the curved surface (convex surface) facing upward and the other with the curved surface facing downward. Channel III is equipped with a reversing device. When the curved surface of the clip on channel III is facing upward, the reversing device allows the clips on channel III to be flipped to a flat surface (concave surface) facing upward when transferred to channel IV, so that all the clips on channel IV are in the curved surface facing downward state. At this time, the clips transferred to channel IV are all in a horizontal position with the curved surface facing downward and the large end facing forward. Channel IV is equipped with a biasing device. The clips on channel IV continue to be transferred forward, and the biasing device allows the clips to stand sideways, forming a biased state.

[0052] The reversing device includes an arc-shaped slide, a reversing baffle and a baffle. The arc-shaped slide and the baffle are respectively fixed at the outlet of the material channel II. The distance between the baffle and the upper end of the arc-shaped slide forms a reversing entrance. The distance between the baffle and the upper end of the arc-shaped slide is equal to or greater than the height of the clip. In this embodiment, the distance between the baffle and the upper end of the arc-shaped slide is slightly greater than the height of the clip (1-2 cm greater than the height of the clip). One end of the reversing baffle is fixed to the baffle, and the reversing baffle is located in the reversing entrance. The distance between the other end of the reversing baffle and the arc-shaped slide is half the height of the clip or slightly greater than half the height of the clip. The two ends of the arc-shaped slide are respectively connected to the material channel II and the material channel III. The clip enters the reversing entrance and slides from the material channel II to the material channel III through the arc-shaped slide. Since the clip is a semicircular structure with one end larger than the other end, the center of gravity of the clip is located at the large end. With half the height of the clip as the dividing line, the center of gravity of the clip deviates from the dividing line and deviates toward the large end. The baffle is installed in an inclined manner, tilted downward by 10°-15°. Specifically, the baffle is at an angle of 15° to the material channel. The length of the baffle is half the height of the clamp or greater than half the height of the clamp.

[0053] When the clip is conveyed to the turning entrance on channel II, when the large end of the clip faces forward, the center of gravity is located in front of the dividing line (large end end), and the center of gravity of the clip is also located in front of the dividing line. The clip will slide into the turning entrance without moving to the dividing line. At this time, the large end of the clip directly falls into the turning entrance and slides down through the curved slide without hitting the turning stopper. When the small end of the clip faces forward, the center of gravity is located behind the dividing line (large end end), and the center of gravity of the clip is also located behind the dividing line. The clip will not fall until it exceeds the dividing line when moving to the turning entrance. That is, the clip needs to move forward more than half of its height before it falls. At this time, the small end of the clip will continue to move forward to the turning stopper, and the turning stopper will block the small end to prevent it from falling first. At this time, the large end of the clip with the center of gravity biased towards the large end will first fall into the turning entrance and slide down through the curved slide, and the clip will reverse direction with the large end facing forward. Specifically, when the small end of the clip moves forward, the small end will move toward the position of the turning block. When the large end of the clip reaches the turning entrance, the large end of the clip will fall along the slide because its center of gravity is at the turning entrance. At this time, the clip successfully turns direction.

[0054] The reversing mechanism includes a transition channel and an L-shaped plate. The L-shaped plate is positioned at the top of the transition channel, and the gap between the L-shaped plate and the sidewall of the transition channel forms a reversing entrance. The gap between the L-shaped plate and the sidewall of the transition channel is equal to or slightly larger than the radius of the clip, so the clip enters the reversing entrance from the side. The transition channel is connected to Channels III and IV at both ends, respectively. The transition channel is located below the exit of Channel III. The L-shaped plate is flush with the bottom plate of Channel III, which is connected to the entrance of Channel IV. When the clip on Channel III is transferred and dropped into Channel IV, it moves onto the L-shaped plate and falls through the reversing entrance into the transition channel, where it is then transferred to Channel IV. Because the clip has an arc-shaped semicircular structure, its center of gravity is located at the outwardly convex arc. When the clip on Channel III is facing downward, its center of gravity is located downward. When the clip passes through the reversing entrance, it remains heavily weighted and falls downward into Channel III, where it remains facing downward. When the clip on channel III is in an arc-shaped upward position, the center of gravity of the clip is located at the top. When the clip passes through the flip entrance, since the width of the flip entrance is the radius of the clip, the clip needs to fall sideways. Under the influence of the center of gravity, the clip flips during the falling process to form an arc-shaped downward position. At this time, the clip that falls on the transition channel flips to a state with an arc-shaped downward position.

[0055] The offset device includes a rounded corner reversing block, which is a wedge-shaped structure with one end higher than the other. The edge of one side of the upper end of the rounded corner reversing block is an arc-shaped chamfered structure, and the chamfered structure is rounded. The rounded corner reversing block is set on the material channel IV and forms an offset channel with the side wall of the material channel IV. The distance between the rounded corner reversing block and the side wall of the material channel IV is the radius of the clip, and this distance is the offset channel. The width of the material channel IV is also the radius of the clip, so the clip can just stand sideways when it is in the material channel IV. When the clip enters the offset channel, the arc surface of the clip contacts the rounded corner of the offset channel and stands sideways along the rounded corner offset. The clip changes from a lying state to a sideways state. The clip is in a sideways state when it enters the material channel IV.
