Description

Technical Field

[0001] This application relates to the field of automated conveying technology, and in particular to a single-chain transverse accumulation device. Background Technology

[0002] Domestic overhead conveyor technology faces challenges in transporting slender workpieces, especially during 180° turns. Conventional turning methods often require large turning radii, leading to wasted workshop space. To address this issue, a lateral turning method has emerged. In this method, the workpiece is pulled by a single chain on straight sections, while on turning sections, two traction chains synchronously pull both ends of the overhead assembly. Through the horizontal lateral displacement of the workpiece, a storage function is simultaneously achieved.

[0003] However, the two traction chains pulling the workpiece require a high degree of synchronization between the pushers of the two traction chains. If the two pushers cannot maintain strict synchronization, or if one of the pushers fails to properly engage with the lifting claw due to deformation or other reasons, the two ends of the mounting assembly may shift, causing the workpiece to jam on the track.

[0004] Therefore, existing technologies have defects and shortcomings, and need further improvement and development. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a single-chain transverse accumulation device, which aims to solve the problem that the workpiece is easily jammed in the two parallel transverse tracks in the prior art.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: A single-chain transverse accumulation device for suspending and conveying workpieces, the single-chain transverse accumulation device includes a suspension frame and a track assembly, the suspension frame is set on the ground, the track assembly is fixedly set on the suspension frame, the track assembly extends to form a transport route, and the single-chain transverse accumulation device further includes:

[0007] Several carrier groups are slidably arranged on the transport route. Each carrier group is provided with a front head and a rear head that are fixedly arranged at intervals. The front head is provided with a front shovel and a lifting claw that are rotatably connected. The rear head is provided with a rear shovel. The front head and the rear head form a mounting assembly. The mounting assembly is used to mount workpieces.

[0008] A traction chain is installed in the transportation route. The traction chain is fixedly equipped with several pushers, all of which are used to engage with the lifting claw to push the carrier group to move.

[0009] The transportation route is configured as an entrance section, a first lateral movement section, a second lateral movement section, and an exit section, with the angle between the second lateral movement section and the entrance section set as α.

[0010] Optionally, the single-chain transverse accumulation device further includes:

[0011] Train set track, which is located below the traction chain;

[0012] A plurality of stoppers are fixedly installed on the side of the transport route. The plurality of stoppers are used to raise or lower the front shovel and control whether the pusher head and the lifting claw are engaged.

[0013] Optionally, the inlet segment and the outlet segment are arranged in parallel, the first lateral segment and the second lateral segment are arranged in parallel and spaced apart, and both the first lateral segment and the second lateral segment are connected to the inlet segment and the outlet segment.

[0014] Optionally, α is set to 20° to 30°.

[0015] Optionally, a first stop is provided at the intersection of the first lateral section and the entrance section, and a second stop is provided at the first lateral section near the exit section; a third stop, a traction chain winding machine, and an automatic lifting machine are provided at the intersection of the first lateral section near the exit section, and the traction chain winding machine is used to wind the traction chain back from the first lateral section to the entrance section.

[0016] Optionally, the automatic lifting machine, the first stop, the second stop, and the third stop each include a telescopic module, a triangular block, a connecting shaft, and a supporting shovel. The triangular block is provided with a first movable hinge point, a second fixed hinge point, and a third movable hinge point. The first movable hinge point is rotatably connected to the telescopic module, the second fixed hinge point is fixedly disposed on the side of the track assembly, and the third movable hinge point is rotatably connected to the supporting shovel.

[0017] When the telescopic module extends, the triangular block rotates around the second fixed hinge point, causing the connecting shaft to rotate, which in turn causes the supporting shovel to rotate counterclockwise, making the supporting shovel contact the front shovel and disengaging the carrier assembly from the traction chain. When the telescopic module retracts, the triangular block rotates around the second fixed hinge point, causing the connecting shaft to rotate, which in turn causes the supporting shovel to rotate clockwise, preventing the supporting shovel from contacting the front shovel and engaging the carrier assembly with the traction chain.

[0018] Optionally, the front shovel includes a swing shaft, a counterweight, and a roller. The counterweight is fixedly mounted on the swing shaft, which is rotatably connected to the lifting claw. The roller is located at the end of the swing shaft opposite to the lifting claw. The roller is used to reduce the rolling friction of the front shovel. The counterweight is used to keep the lifting claw, which is rotatably connected to the swing shaft, in a raised state. The automatic lifting machine also includes a long support plate, which is sleeved on the supporting shovel. The length of the long support plate is set according to the length of the stopping area of ​​the carrier group. The length of the long support plate is 1.5 meters to 1.8 meters. The long support plate is used to ensure that the lifting claw is in a lowered state and that the pusher is disengaged from the lifting claw.

[0019] Optionally, the track assembly includes a suspension adjustment component and a double-rail flange arranged sequentially from top to bottom, with the double-rail flange fixed below the suspension adjustment component; the double-rail flange is provided with a traction track groove, a connecting cavity, and a track groove arranged from top to bottom, the traction track groove being used to place the traction chain track, and the connecting cavity being used for the movement of the pusher and lifting claw.

[0020] Optionally, the suspension adjustment component includes a load-bearing steel beam, a pressure plate, and an adjustable connecting plate arranged sequentially from top to bottom, with the load-bearing steel beam locked between the pressure plate and the adjustable connecting plate.

[0021] Optionally, the single-chain transverse accumulation device further includes a plurality of control sensors, which are disposed in the automatic lifting machine, the first stop, the second stop, and the third stop. The plurality of control sensors are all used to control the extension and retraction of the telescopic module, and the plurality of control sensors are electrically connected to each other.

[0022] Compared with the prior art, this application provides a single-chain lateral transfer accumulation device. This device sets the traction chain as a single chain when the front and rear carrier groups enter the first and second lateral transfer sections, respectively. The traction chain enters the first lateral transfer section but not the second, leaving the rear carrier group in a powerless state. Under the influence of the component force of the traction force from the front carrier group, the rear carrier group enters the second lateral transfer section. Thus, the lateral transfer and accumulation of workpieces can be achieved using only a single traction chain. Furthermore, by designing the traction chain to first detach and then reverse into the track to pull the other end of the carrier group, it enables turning and reversing operations. This overcomes the synchronization and parallelism problems of dual-chain traction, significantly reducing the failure rate, and also reducing the length of the traction chain and the complexity of the system.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] Please refer to the following: Figures 1 to 4 The first embodiment of this application provides a single-chain transverse accumulation device 10, which includes a traction chain 14 and several carrier trolleys 13. The trolleys slide along a track to form a conveying path. Several pushers 141 are fixed on the traction chain 14 sliding on the track. The pushers 141 engage with the lifting claws 1312 of the carrier trolleys 13, driving the trolleys to move along the transport route 121. Each carrier trolley 13 is provided with a front head 131 and a rear head 132, which can not only stably support the workpiece but also protect the mounted workpiece. The single-chain transverse accumulation device 10 can automatically disengage and engage the lifting claws 1312 with the pushers 141. When a carrier group 13 is stopped on a section of the transport route 121, the following carrier group 13 continues to move forward. Its front shovel 1311 will contact the rear shovel 1321 of the preceding group. At this time, the rear lifting claw 1312 will automatically disengage from the pusher head 141, forming a stacking separation state. This prevents the following group from pushing the preceding group, avoiding mutual collisions when the workpieces are stacked, and ensuring the safety of the workpieces during movement. A first stop 161 is provided at the intersection of the first lateral section 1212 and the entrance section 1211. A second stop 162 is provided near the exit section 1214 of the first lateral section 1212. A third stop 163 is provided near the intersection of the first lateral section 1212 and the exit section 1214. The first stop 161, the second stop 162, and the third stop 163 are all used to control the stopping and moving of the carrier group 13. The stoppers at different positions raise or lower the front shovel 1311 to control the engagement of the lifting claw 1312 and the pusher head 141. Specifically, when the stopper needs to pause the train, it raises the front shovel 1311 to a designated height, disengaging the pusher head 141 from the lifting claw 1312, and the train stops immediately. When the stopper returns the front shovel 1311 to its original position, the lifting claw 1312 re-engages with the pusher head 141, and the conveying action continues. This segmented control makes the conveying rhythm of the device more flexible and allows for precise stops at different positions as needed.

[0040] Please refer to the following: Figure 3The overall conveying route of the single-chain transverse accumulation device 10 is divided into an inlet section 1211, a first transverse section 1212, a second transverse section 1213, and an outlet section 1214. The first transverse section 1212 and the second transverse section 1213 are arranged in parallel, with the inlet and outlet located at opposite ends. Through a reasonable path layout, workpieces flow at different angles, adapting to complex factory layouts. When the front and rear carrier groups enter the first transverse section 1212 and the second transverse section 1213 respectively, since the traction chain 14 is a single traction chain, it will enter the first transverse section 1212 but not the second transverse section 1213. That is, the rear carrier group is in a non-powered state. Because the angle between the second transverse section 1213 and the inlet section 1211 is set to 20°–30°, the rear... The carrier train sets enter the second transverse section 1213 under the traction force of the front carrier train sets, and the rear carrier train sets enter the second transverse section 1213 under the traction force of the front carrier train sets. This avoids the problem in existing technologies where two traction chains pull the workpiece, and the pushers of the two traction chains are not synchronized, causing the two ends of the mounting components to shift and the workpiece to get stuck on the track. It also reduces the idle chain winding by 50%, and eliminates the need for adjustment mechanisms at the pusher positions of the traction chains. The overall structure is simple, the chain length of the traction chains is greatly shortened, and nearly 50% of material costs and complex maintenance work are saved. At the same time, the traction chain 14 is wound back to the exit section 1214 by the traction chain winding machine 1215 at the exit section 1214, realizing a 180° chain reversal and completing the closed-loop conveying. An automatic lifting mechanism 1216 is installed at this location. Through a telescopic module 164 and a front shovel 1311, it enables the uncoupling of the carrier train 13. When the train needs to stop, the lifting mechanism raises the supporting shovel 167, disengaging the front shovel 1311 from the pusher head 141, ensuring the train remains stationary. Under normal conditions, the supporting shovel 167 remains in its original position, ensuring the train can continue moving along the path. The front shovel 1311 is equipped with rollers 1315, reducing friction during movement. Simultaneously, a counterweight 1314 ensures that the lifting claw 1312 is in a raised state when the front shovel 1311 is not in use. The design of the counterweight and rollers 1315 effectively avoids resistance caused by excessive friction while enabling the lifting claw 1312 to uncouple, ensuring the smooth operation of the carrier train 13. The suspension adjustment assembly of the single-chain transverse accumulation device 10 achieves height adjustment through the load-bearing steel beam 1221 and the clamping plate 1222, while the double-rail flange 123 ensures smooth sliding of each component during transportation. The double-rail flange 123, arranged below the suspension adjustment assembly, includes a traction track groove 1231, a connecting cavity 1232, and a vehicle track groove 1233, which not only meets the stable sliding requirements of each component on the track but also ensures adjustment requirements at different heights and positions.The single-chain transverse accumulation device 10 employs automated control. Through sensors installed on each stop and the automatic lifting machine 1216, it can monitor the position of the train sets on the conveying path in real time and coordinate start-stop operations, avoiding congestion or collisions caused by too many train sets clustering in the same area. This automated control allows the single-chain transverse accumulation device 10 to adjust the position and movement status of the train sets promptly through sensor signal feedback, giving it high safety, reliability, and efficiency.

[0041] Please refer to the following: Figures 2 to 5 In some embodiments, the single-chain lateral accumulation device 10 includes a suspension frame 11 and a track assembly 12. The suspension frame 11 is mounted on the ground, and the track assembly 12 is fixedly mounted on the suspension frame 11. The track assembly 12 extends to form a transport route 121. The single-chain lateral accumulation device 10 also includes a traction chain 14 and several carrier assemblies 13. The carrier assemblies 13 are slidably mounted on the transport route 121. Each carrier assembly 13 has a front end 131 and a rear end that are fixedly spaced apart. 132, the front cab 131 is provided with a front shovel 1311 and a lifting claw 1312 rotatably connected, and the rear cab 132 is provided with a rear shovel 1321. The front cab 131 and the rear cab 132 form a mounting assembly, which is used to mount workpieces; the traction chain 14 is set in the transport route 121, and the traction chain 14 is fixedly provided with a plurality of push heads 141, which are used to engage with the lifting claw 1312 to push the carrier assembly 13 to move; wherein, the carrier assembly located at the front When the 13th carrier group stops, the front shovel 1311 of the rear carrier group 13 will contact the rear shovel 1321 of the front carrier group 13, causing the lifting claw 1312 of the rear carrier group 13 to disengage from the pusher head 141. The transport route is configured as an entrance section, a first lateral section, a second lateral section, and an exit section, with the angle between the second lateral section and the entrance section set as α. The single-chain lateral accumulation device 10 enters the first lateral section 1212 and the second lateral section 1321 through the front and rear carrier groups, respectively. During the second lateral movement segment 1213, the traction chain 14 is configured as a single traction chain 14. The traction chain 14 will enter the first lateral movement segment 1212 but will not enter the second lateral movement segment 1213, leaving the rear carrier assembly in a powerless state. Under the influence of the traction force component of the front carrier assembly, the rear carrier assembly will enter the second lateral movement segment 1213. This avoids the problem in the prior art where two traction chains 14 pull the workpiece, and the pushers 141 of the two traction chains 14 are not synchronized, causing the two ends of the mounting assembly to shift and resulting in the workpiece getting stuck on the track. This further ensures the stability of the workpiece during the suspended transport process, reduces the probability of the workpiece getting stuck on the track, and effectively improves the safety and efficiency of the single-chain lateral movement accumulation device 10 in transporting workpieces.

[0042] Please refer to the following: Figure 1 In some embodiments, the single-chain transverse accumulation device 10 further includes a train set track 15 and several stops. The train set track 15 is located below the traction chain 14. The several stops are fixedly installed on the side of the transport route 121. Each stop is used to raise or lower the front shovel 1311 and control whether the pusher head 141 engages with the lifting claw 1312. Specifically, when the loading assembly is about to reach the designated position, the stop is pushed to the closed position 2-3 seconds in advance. After the carrying train set 13 arrives, the front shovel 1311 is lifted by the sloping shovel of the stop, the train set lifting claw 1312 descends, disengages from the traction chain 14, the pusher head 141 loses power, and is blocked by the sloping shovel. Upon receiving a release command, the stop cylinder actuates, the sloping shovel tilts outward by 90°, the sloping shovel leaves the train set position, the train set front shovel 1311 is released, and the lifting claw 1312 rises to wait for the next pusher head 141 to come and take away the workpiece. This waiting time is the running time of one pusher head 141 interval. Then, by raising or lowering the front shovel 1311, the engagement state of the pusher head 141 and the lifting claw 1312 is controlled, so that the carrier vehicle 13 can stop or continue to transport as needed, which facilitates accurate positioning and control of the workpiece in the transport path.

[0043] In some embodiments, a backstop claw is also provided behind the lifting claw 1312. The front shovel 1311 is in a sunken state under gravity in its natural state. At this time, the lifting claw 1312 is lifted to a high position, and the backstop claw is also lifted to a high position by the lifting claw 1312. However, the backstop claw can swing in one direction. When the pusher head 141 approaches, it will first encounter the backstop claw, which swings downwards. After the pusher head 141 passes the backstop claw, it engages with the lifting claw 1312, generating thrust. This prevents the carrier assembly 13 from reversing under gravity and colliding with other workpieces.

[0044] Please refer to the following: Figure 3 In some embodiments, the transport route 121 is configured as an entrance section 1211, a first lateral movement section 1212, a second lateral movement section 1213, and an exit section 1214. The entrance section 1211 and the exit section 1214 are arranged parallel to each other, and the first lateral movement section 1212 and the second lateral movement section 1213 are arranged parallel to each other at intervals. Both the first lateral movement section 1212 and the second lateral movement section 1213 are connected to the entrance section 1211 and the exit section 1214. The angle between the second lateral movement section 1213 and the entrance section 1211 is set to α. This allows for a reasonable layout of each path segment. In particular, the arrangement of the lateral movement sections avoids the overlap of multiple paths at the same location, which helps to save factory space and improve space utilization efficiency. Through the horizontal lateral movement traction of a single chain, and the fact that the traction chain 14 can turn back 180°, the synchronization problem of double chain traction is fundamentally avoided.

[0045] In some embodiments, the spacing between the plurality of pushers 141 can be calculated based on the linear speed and production cycle time, and then the pushers 141 are installed on the traction chain 14 at this spacing. When the traction chain 14 is running, a fixture engages with only one pusher 141 at a time. For structures that require lateral accumulation, the carrier assemblies 13 on different workpiece fixtures are identical combinations, thereby ensuring that the carrier assemblies 13 can also accumulate normally in the first lateral section 1212 and the second lateral section 1213.

[0046] Please refer to the following: Figure 3 In some embodiments, α is set to 20° to 30°, which allows the unpowered rear carrier group to slide onto the second transverse section 1213 under the traction of the front carrier group, reducing the contact friction between the carrier group 13 and the second transverse section 1213, and further greatly improving the overall operating efficiency of the single-chain transverse accumulation device 10.

[0047] Please refer to the following: Figure 1 In some embodiments, a first stopper 161 is provided at the intersection of the first transverse section 1212 and the entrance section 1211, and a second stopper 162 is provided at the intersection of the first transverse section 1212 and the exit section 1214; a third stopper 163, a traction chain winding machine 1215, and an automatic lifting machine 1216 are provided at the intersection of the first transverse section 1212 and the exit section 1214. Specifically, the traction chain winding machine 1215 is existing technology. The traction chain winding machine 1215 is used to wind the traction chain 14 from the first transverse section 1212 back to the entrance section 1211, thereby achieving a stable transition at the intersection of the first transverse section 1212 and the exit section 1214, preventing the tension of the traction chain 14 from interfering with the train set, and the stopper controls the parking of the train set at the path intersection point to avoid workpiece accumulation in the transverse section, making the workpiece conveying process smoother.

[0048] Please refer to the following: Figures 6 to 9In some embodiments, the automatic lifting machine 1216, the first stopper 161, the second stopper 162, and the third stopper 163 each include a telescopic module 164, a triangular block 165, a connecting shaft 166, and a supporting shovel 167. The triangular block 165 is provided with a first movable hinge point 1651, a second fixed hinge point 1652, and a third movable hinge point 1653. The first movable hinge point 1651 is rotatably connected to the telescopic module 164, the second fixed hinge point 1652 is fixedly disposed on the side of the track assembly 12, and the third movable hinge point 1653 is rotatably connected to the supporting shovel 167. When the telescopic module 164 extends, the triangular block 165 rotates around the second fixed hinge point... Contact 1652 drives the connecting shaft 166 to rotate, which in turn drives the supporting shovel 167 to rotate counterclockwise, causing the supporting shovel 167 to contact the front shovel 1311, thus disengaging the carrier assembly 13 from the traction chain 14. When the telescopic module 164 retracts, the triangular block 165 drives the connecting shaft 166 to rotate around the second fixed hinge point 1652, which in turn drives the supporting shovel 167 to rotate clockwise, preventing the supporting shovel 167 from contacting the front shovel 1311, thus engaging the carrier assembly 13 with the traction chain 14. This allows for precise control of the contact between the supporting shovel 167 and the front shovel 1311, reducing impact during workpiece disengagement and engagement, and protecting the connecting components of the assembly and the traction chain 14.

[0049] Please refer to the following: Figure 7 and Figure 8 In some embodiments, the front shovel 1311 includes a swing shaft 1313, a counterweight 1314, and a roller 1315. The counterweight 1314 is fixedly mounted on the swing shaft 1313, which is rotatably connected to the lifting claw 1312. The roller 1315 is located at one end of the swing shaft 1313 away from the lifting claw 1312. The roller 1315 is used to reduce the rolling friction of the front shovel 1311, thereby enabling it to contact the track more smoothly during operation, effectively reducing wear and friction, and improving the service life of the front shovel 1311. The counterweight 1314 is used to keep the lifting claw 1312, which is rotatably connected to the swing shaft 1313, in a raised state.

[0050] Please refer to the following: Figure 7 and Figure 8In some embodiments, the automatic lifting machine 1216 further includes a long support plate 1217, which is fitted onto the supporting shovel 167. The length of the long support plate is set according to the length of the stopping area of ​​the carrier group, and the length of the long support plate is 1.5 meters to 1.8 meters. The long support plate is used to ensure that the lifting claw 1312 is in a lowered state and that the pusher head 141 is disengaged from the lifting claw 1312. Specifically, the third stop 163 and the automatic lifting machine 1216 are located on opposite sides of the track to ensure a smooth transition and transmission of the carrier group 13 in the exit section 1214. When the traction chain 14 travels to the third stop 163, it deviates from the track of the exit section 1214 and winds outward under the action of the traction chain winding machine 1215. After winding 180°, the traction chain 14 re-enters the track of the exit section 1214, engages with the lifting claw 1312 of the rear head 132, and propels it forward. Since no automatic lifting mechanism 1216 is installed at the junction of the second lateral section 1213 and the exit section 1214, the lifting claw 1312 of the rear cab 132 remains raised, thus engaging with the pusher 141. This causes the traction chain 14 to push the entire carrier train 13 to move to the right along the exit section 1214, gradually disengaging from the area where the automatic lifting mechanism 1216 is located. Simultaneously, the front cab 131 continues to move to the right until it is above the long pallet of the automatic lifting mechanism 1216. The automatic lifting mechanism 1216 then raises the long pallet, causing the lifting claw 1312 of the front cab 131 to descend, preventing the front cab 131 from engaging with the subsequent pusher 141. Before the front cab 131 completely disengages from the range of the automatic lifting mechanism 1216 and leaves the exit section 1214, the lifting claw 1312 of the front cab 131 remains in a descending state, ensuring it does not contact the subsequently entering pusher 141. The automatic lifting platform 1216 is located on both sides of the junction of the first lateral section 1212 and the exit section 1214, thus preventing interference between the front head 131 and the rear head 132 due to the pusher 141 in opposite directions. After the front head 131 has completely left the range of the automatic lifting platform 1216, its lifting claw 1312 returns to its natural state. At this time, the entire carrying unit 13 moves to the right to the entrance section 1211 to complete the transport of the current workpiece. The automatic lifting platform 1216 then lowers the long pallet so that the next carrying unit 13 carrying a workpiece can enter the area under the pusher 141 and proceed to the third stop 163. The long pallet of the automatic lifting platform 1216 rises, and then other carrying units 13 follow the above process to complete the entire cyclic transport process in sequence. This achieves a 180° turnaround of the chain while greatly reducing the floor space occupied by the single-chain lateral transport and accumulation device 10, and avoids the synchronization problem of double-chain traction in principle.

[0051] Please refer to the following: Figure 10In some embodiments, the track assembly 12 includes a suspension adjustment member 122 and a double-rail flange 123 arranged sequentially from top to bottom. The double-rail flange 123 is fixed below the suspension adjustment member 122. The double-rail flange 123 is provided with a traction track groove 1231, a connecting cavity 1232, and a track groove 1233 arranged from top to bottom. The traction track groove 1231 is used to place the traction chain 14 track, thereby ensuring the stability of the traction chain 14 track and preventing the track from shifting during long-term use. The connecting cavity 1232 is used for the movement of the push head 141 and the lifting claw 1312, thereby providing sufficient movement space for the push head 141 and the lifting claw 1312, ensuring the smooth operation of the suspension adjustment member 122 during the lateral movement of the single-chain lateral accumulation device 10, and reducing the risk of interference between components.

[0052] Please refer to the following: Figure 10 In some embodiments, the suspension adjustment component 122 includes a load-bearing steel beam 1221, a pressure plate 1222, and an adjustable connecting plate 1223 arranged sequentially from top to bottom. The load-bearing steel beam 1221 is locked between the pressure plate 1222 and the adjustable connecting plate 1223, thereby increasing the flexibility of the suspension structure and enabling the track assembly 12 to be finely adjusted during installation to adapt to different working conditions.

[0053] In some embodiments, the single-chain transverse accumulation device 10 further includes several control sensors. These control sensors are disposed in the automatic lifting machine 1216, the first stopper 161, the second stopper 162, and the third stopper 163. Each of the control sensors is used to control the extension and retraction of the telescopic module 164. The control sensors are electrically connected to each other, thereby controlling the extension and retraction of the telescopic module 164 through the control sensors, realizing the automatic adjustment and positioning of the carrier group 13, and ensuring the safety and stability of the single-chain transverse accumulation device 10.

[0054] In some implementations, the carrier trains at the front are arranged with the front locomotive in front and the rear locomotive in back, while the carrier trains at the rear are arranged with the rear locomotive in front and the front locomotive in back. All other carrier trains are arranged in this order, thereby enabling the carrier trains to operate in both directions.

[0055] Please refer to the following: Figure 11 When the pusher of the traction chain engages with the lifting claw in front, it pushes the carrier group to move forward. When the traction chain returns from the first lateral section to the entrance section under the action of the traction chain winding machine, the lifting claw in the rear engages with the pusher of the traction chain, pushing the carrier group to move in the opposite direction.

[0056] In summary, this application provides a single-chain lateral transfer accumulation device, which includes a suspension frame and a track assembly. The suspension frame is disposed on the ground, and the track assembly is fixedly disposed on the suspension frame. The track assembly extends to form a transport route. The single-chain lateral transfer accumulation device further includes: a plurality of carrier trolleys, each of which is slidably disposed on the transport route. Each carrier trolley has a front head and a rear head fixedly disposed at intervals. The front head is provided with a front shovel and a lifting claw rotatably connected, and the rear head is provided with a rear shovel. The front head and the rear head form a mounting assembly for mounting workpieces. A traction chain is disposed in the transport route and is fixedly disposed with a plurality of pushers, each of which is used to engage with the lifting claw to push the carrier trolleys to move. The transport route is configured as an inlet section, a first lateral transfer section, a second lateral transfer section, and an outlet section, with the angle between the second lateral transfer section and the inlet section set as α. This design avoids the problem in existing technologies where two traction chains pull the workpiece, and the pushers of the two traction chains are not synchronized, causing the two ends of the mounting components to shift and the workpiece to get stuck on the track. Furthermore, by designing the traction chain to first detach and then reverse back into the track to pull the other end of the train, it enables turning and reversing operation. This further ensures the stability of the workpiece during the horizontal lateral movement of the suspended conveyor, overcomes the synchronization and parallelism problems of dual-chain traction, greatly reduces the failure rate, and also reduces the length of the traction chain and the complexity of the system.

[0057] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
