[0022] Please refer to Figures 1 to 4 The first embodiment of the present application provides a single-chain transverse shifting accumulation device 10, which includes a traction chain 14 and a plurality of load-bearing vehicle groups 13, and the vehicle groups slide along the track to form a conveying path. A plurality of push heads 141 are fixed on the traction chain 14 sliding on the track, and the push heads 141 are engaged with the lifting claws 1312 of the load-bearing vehicle groups 13 to drive the vehicle groups to move along the transportation route 121. A front head 131 and a rear head 132 are provided on each load-bearing vehicle group 13, which can stably support the workpiece and protect the mounted workpiece to avoid collision and damage during transportation. In case the workpiece collides during travel, the single-chain transverse shifting accumulation device 10 can realize automatic uncoupling and engagement of the lifting claw 1312 and the push head 141. When the front load-carrying vehicle group 13 is stopped on a section of the transport route 121, the rear load-carrying vehicle group 13 continues to move forward, and its front shovel 1311 will contact the rear shovel 1321 of the front vehicle group. At this time, the rear lifting claw 1312 will automatically disengage from the push head 141, forming a stacking separation state, so that the subsequent vehicle group no longer pushes the front vehicle group, avoiding mutual collision when the workpieces are piled up, and ensuring the safety of the workpieces during movement. 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 first transverse section 1212 near the exit section 1214; a third stopper 163 is provided at the intersection of the first transverse section 1212 near the exit section 1214. The first stopper 161, the second stopper 162 and the third stopper 163 are all used to control the pause and movement of the load-carrying vehicle group 13. The stoppers at different positions will raise or lower the front shovel 1311 to control the engagement of the lifting claw 1312 with the pusher head 141. Specifically, when the stopper needs to control the vehicle group to pause, the front shovel 1311 will be raised to a specified height, so that the pusher head 141 will be disengaged from the lifting claw 1312, and the vehicle group will stop immediately; when the stopper restores the front shovel 1311 to its original position, the lifting claw 1312 will re-engage with the pusher head 141 and continue the conveying action. This segmented control makes the conveying rhythm of the device more flexible and can achieve precise pauses at different positions according to needs.

[0023] Please refer to Figure 3The overall conveying route of the single-chain transverse accumulation device 10 is divided into an entrance section 1211, a first transverse section 1212, a second transverse section 1213 and an exit section 1214. The first transverse section 1212 and the second transverse section 1213 are arranged in parallel, and the entrance and the exit are respectively located at both ends. Through a reasonable path layout, the workpieces are circulated at different angles, which can adapt to complex factory layouts. When the front load-bearing vehicle group and the rear load-bearing vehicle group enter the first transverse section 1212 and the second transverse section 1213 respectively, since the traction chain 14 is a single traction chain 14, the traction chain 14 will enter the first transverse section 1212 and will not enter the second transverse section 1213, that is, the rear load-bearing vehicle group is in an unpowered state. Since the second transverse section 1213 and the entrance section 12 The angle of 11 is set to 20°~30°, and the rear load-bearing vehicle group will enter the second transverse shift section 1213 under the component force of the traction force of the front load-bearing vehicle group, thereby not only avoiding the problem of two traction chains pulling the workpiece in the prior art, but also reducing 50% of the idle chain winding, and there is no need to set an adjustment mechanism at the push head position of the traction chain. The overall structure is simple, the chain length of the traction chain is greatly shortened, and nearly 50% of the material cost 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° return of the chain and completing closed-loop transportation. The automatic plate lifter 1216 cooperates with the front shovel 1311 through the telescopic module 164 to realize the uncoupling operation of the load-bearing vehicle group 13. When the vehicle group needs to stop, the plate lifter will lift the supporting shovel 167 to uncouple the front shovel 1311 from the push head 141 to ensure that the vehicle group stays; under normal conditions, the supporting shovel 167 remains in place to ensure that the vehicle group can continue to move forward along the path. The front shovel 1311 is provided with a roller 1315 to reduce the friction during movement. At the same time, the 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 roller 1315 effectively avoids the resistance caused by excessive friction while realizing the uncoupling of the lifting claw 1312, ensuring the smooth operation of the load-bearing vehicle group 13. The suspension adjustment component of the single-chain transverse accumulation device 10 is height-adjustable through the load-bearing steel beam 1221 and the clamping plate 1222, and the double-track flange 123 is provided to ensure the smooth sliding of each component during transportation. The double-track flange 123 arranged below the suspension adjustment component includes a traction track groove 1231, a docking cavity 1232 and a vehicle track groove 1233, which can not only meet the stable sliding requirements of each component on the track, but also ensure the adjustment requirements at different heights and positions. The single-chain transverse accumulation device 10 adopts automatic control. Through the sensors installed on each stopper and the automatic plate lifter 1216 sensor, it can monitor the position of the vehicle group on the conveying path in real time and coordinate the start and stop operations, avoiding blockage or collision caused by too many vehicle groups gathering in the same area.This automated control of the single-chain transverse shifting and accumulating device 10 timely adjusts the position and movement state of the vehicle group through the signal feedback of the sensor, so that the single-chain transverse shifting and accumulating device 10 has higher safety, reliability and efficiency.

[0024] Please refer to Figures 2 to 5 In some embodiments, the single-chain transverse shifting accumulation device 10 includes a suspension frame 11 and a track assembly 12, the suspension frame 11 is arranged on the ground, the track assembly 12 is fixedly arranged on the suspension frame 11, and the track assembly 12 extends to form a transportation route 121. The single-chain transverse shifting accumulation device 10 also includes a traction chain 14 and a plurality of load-bearing vehicle groups 13, and the plurality of load-bearing vehicle groups 13 are all slidably arranged on the transportation route 121. The load-bearing vehicle group 13 is provided with a front head 131 and a rear head 132 that are fixedly arranged at intervals, the front head 131 is provided with a front shovel 1311 and a lifting claw 1312 that are rotatably connected, and the rear head 132 is provided with a rear shovel 1321, and the front head 131 and the rear head 132 form a mounting assembly, and the mounting assembly is used to mount the workpiece; the traction chain 14 is arranged on the transportation In route 121, the traction chain 14 is fixedly provided with a plurality of push heads 141, and the push heads 141 are used to engage with the lifting claws 1312 to push the carrying vehicle group 13 to move; wherein, when the carrying vehicle group 13 located in the front stops, the front shovel 1311 of the carrying vehicle group 13 located in the rear will contact with the stopped rear shovel 1321 of the carrying vehicle group 13 located in the front, so that the lifting claws 1312 of the carrying vehicle group 13 located in the rear are decoupled from the push heads 141, thereby preventing the workpiece from being stuck on the track due to the untimely synchronization of the push heads in the two parallel transverse tracks, thereby further ensuring the stability of the workpiece during the suspension transportation process, reducing the probability of the workpiece getting stuck on the track, and effectively improving the safety and efficiency of the single-chain transverse accumulation device 10 in transporting workpieces.

[0025] Please refer to Figure 1In some embodiments, the single-chain transverse accumulation device 10 further includes a vehicle group track 15 and a plurality of stoppers, wherein the vehicle group track 15 is arranged below the traction chain 14; a plurality of the stoppers are fixedly arranged on the side of the transport route 121, and the plurality of the stoppers are used to lift or lower the front shovel 1311, and control whether the pusher head 141 is engaged with the lifting claw 1312. Specifically, when the mounting assembly is about to reach the specified position, the stopper is pushed to the closed position 2 to 3 seconds in advance. After the load-bearing vehicle group 13 arrives, the front shovel 1311 will be lifted by the oblique shovel of the stopper, and the vehicle group lifting claw 1312 will drop, detach from the pusher head 141 of the traction chain 14, thereby losing power and being blocked by the oblique shovel. After receiving the release command, the stopper cylinder is actuated, the oblique shovel is turned outward 90°, the oblique shovel leaves the vehicle group position, the vehicle group front shovel 1311 is released, and the lifting claw 1312 is raised 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, and then by raising or lowering the front shovel 1311 to control the meshing state of the pusher head 141 and the lifting claw 1312, the carrying vehicle group 13 can stop or continue to transport as needed, which is convenient for accurate positioning and control of the workpiece in the conveying path.

[0026] In some embodiments, a back-stop claw is further provided behind the lifting claw 1312. The front shovel 1311 is in a sinking state due to gravity in a natural state. At this time, the lifting claw 1312 is lifted up at a high position, and the back-stop claw is also lifted up at a high position by the lifting claw 1312. However, the back-stop claw can swing in one direction. When the push head 141 comes over, it will first hit the back-stop claw, and the back-stop claw swings downward. After the push head 141 passes over the back-stop claw, it engages with the lifting claw 1312 to generate thrust, thereby preventing the load-bearing vehicle group 13 from retreating under the action of gravity and colliding with other workpieces.

[0027] Please refer to Figure 3 In some embodiments, the transport route 121 is configured to include an entrance section 1211, a first transverse section 1212, a second transverse section 1213 and an exit section 1214, the entrance section 1211 is arranged in parallel with the exit section 1214, the first transverse section 1212 and the second transverse section 1213 are arranged in parallel and spaced apart, the first transverse section 1212 and the second transverse section 1213 are both connected to the entrance section 1211 and the exit section 1214, and the angle between the second transverse section 1213 and the entrance section 1211 is set to α, so that each section of the path can be reasonably arranged, especially the setting of the transverse section, which avoids the overlap of multiple paths at the same position, helps to save factory space and improve space utilization efficiency, and fundamentally avoids the synchronization problem of double-chain traction through single-chain traction.

[0028] In some embodiments, the spacing between the plurality of pushers 141 can be calculated based on the line speed and the production rhythm, and then the pushers 141 are installed on the traction chain 14 according to the spacing. When the traction chain 14 is running, one hanger is only engaged with one pusher 141 at the same time. For structures that require lateral accumulation, the load-bearing vehicle groups 13 on different workpiece hangers are exactly the same combination, thereby ensuring that the load-bearing vehicle groups 13 can also accumulate normally in the first lateral movement section 1212 and the second lateral movement section 1213.

[0029] Please refer to Figure 3 In some embodiments, the angle α is set to 20°~30°, so that the unpowered rear load-bearing vehicle group can slide onto the second transverse section 1213 under the traction force of the front load-bearing vehicle group, thereby reducing the contact friction between the load-bearing vehicle group 13 and the second transverse section 1213, and further greatly improving the overall operating efficiency of the single-chain transverse accumulation device 10.

[0030] Please refer to 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 first transverse section 1212 near the exit section 1214; a third stopper 163, a traction chain unwinding machine 1215 and an automatic plate lifting machine 1216 are provided at the intersection of the first transverse section 1212 near the exit section 1214, and the traction chain unwinding machine 1215 is used to wind the traction chain 14 from the first transverse section 1212 back to the entrance section 1211, thereby realizing a stable conversion 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 vehicle group, and the stopper controls the parking of the vehicle group at the intersection of the path to avoid the accumulation of workpieces in the transverse section, thereby making the workpiece conveying process smoother.

[0031] Please refer to Figures 6 to 9In some embodiments, the automatic plate lifter 1216, the first stopper 161, the second stopper 162 and the third stopper 163 all include a telescopic module 164, a triangular block 165, a connecting shaft 166 and a supporting shovel 167, and 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 arranged 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 is extended, the triangular block 165 is rotated around the second fixed hinge point The contact point 1652 drives the connecting shaft 166 to rotate, and then drives the supporting shovel 167 to rotate counterclockwise, so that the supporting shovel 167 contacts the front shovel 1311, so that the load-bearing vehicle group 13 is separated from the traction chain 14; when the telescopic module 164 contracts, the triangular block 165 drives the connecting shaft 166 to rotate around the second fixed hinge point 1652, and then drives the supporting shovel 167 to rotate clockwise, so that the supporting shovel 167 does not contact the front shovel 1311, so that the load-bearing vehicle group 13 is engaged with the traction chain 14, thereby achieving precise control of the contact between the supporting shovel 167 and the front shovel 1311, which can reduce the impact when the workpiece is unhooked and engaged, and protect the joint parts of the vehicle group and the traction chain 14.

[0032] Please refer to 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 arranged on the swing shaft 1313. The swing shaft 1313 is rotatably connected to the lifting claw 1312. The roller 1315 is arranged 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, so that it can contact the track more smoothly during operation, effectively reduce wear and friction, and improve the service life of the front shovel 1311; the counterweight 1314 is used to keep the lifting claw 1312 rotatably connected to the swing shaft 1313 in a raised state.

[0033] Please refer to Figure 7 and Figure 8In some embodiments, the automatic plate lifter 1216 also includes a long stripping plate 1217, which is sleeved on the supporting shovel 167, and the length of the long stripping plate is set to 1.8 meters to 2 meters. The long stripping plate is used to ensure that the lifting claw 1312 is in a lowered state, and the push head 141 is unhooked from the lifting claw 1312, so that the load-bearing vehicle group 13 can be achieved in the exit section 1214. When the traction chain 14 has not returned to the exit section 1214 from the winding machine, that is, within the length range of the long stripping plate, the lifting claw 1312 of the load-bearing vehicle group 13 does not contact the push head 141, and when the traction chain 14 enters the exit section 1214, the long stripping plate 1217 is lowered, so that the push head 141 is engaged with the lifting claw 1312, and the load-bearing vehicle group 13 is driven to leave the exit section 1214, realizing a 180° return of the chain, greatly reducing the footprint of the single-chain transverse shifting accumulation device 10, and avoiding the synchronization problem of double-chain traction in principle.

[0034] Please refer to Fig.10 In some embodiments, the track assembly 12 includes a suspension adjustment member 122 and a double-track flange 123 arranged in sequence from top to bottom, and the double-track flange 123 is fixed below the suspension adjustment member 122; the double-track flange 123 is provided with a traction track groove 1231, a docking cavity 1232 and a vehicle track groove 1233 from top to bottom, and the traction track groove 1231 is used to place the traction chain 14 track, thereby ensuring the firmness of the traction chain 14 track and preventing the track from shifting during long-term use; the docking 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 of the single-chain transverse accumulation device 10 during the transverse movement process, and reducing the risk of interference between components.

[0035] Please refer to Fig.10 In some embodiments, the suspension adjustment member 122 includes a load-bearing steel beam 1221, a clamping plate 1222 and an adjustable connecting plate 1223 arranged in sequence from top to bottom. The load-bearing steel beam 1221 is locked between the clamping 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 the installation process to adapt to different working conditions.

[0036] In some embodiments, the single-chain transverse movement and accumulation device 10 also includes a plurality of control sensors, and the plurality of control sensors are arranged in the automatic plate lift 1216, the first stopper 161, the second stopper 162 and the third stopper 163. The plurality of control sensors are used to control the extension and retraction of the telescopic module 164. The plurality of control sensors are electrically connected to each other, and the extension and retraction of the telescopic module 164 are controlled by the control sensors, thereby realizing automatic adjustment and positioning of the load-bearing vehicle group 13, and ensuring the safety and stability of the single-chain transverse movement and accumulation device 10.

[0037] In some embodiments, the load-bearing vehicle group located in the front adopts a configuration in which the front locomotive is in front and the rear locomotive is in the rear, and the load-bearing vehicle group located in the rear adopts a configuration in which the rear locomotive is in front and the front locomotive is in the rear, and other load-bearing vehicle groups are arranged in this order, thereby allowing the load-bearing vehicle groups to operate in both directions.

[0038] Please refer to Fig.11 When the push head of the traction chain engages with the lifting claw at the front, the load-bearing vehicle group is pushed to move forward. When the traction chain is wound back from the first transverse section to the entrance section under the action of the traction chain winding machine, the lifting claw at the rear engages with the push head of the traction chain, pushing the load-bearing vehicle group to move in the reverse direction.

[0039] Please refer to Fig.12 The second embodiment of the present application provides an operation method based on the single-chain transverse accumulation device as described above, and the operation method includes: S100, the traction chain pushes the load-bearing vehicle group forward along the transportation route, wherein the front head of the load-bearing vehicle group is at the front end in the running direction of the workpiece; when the front of the load-bearing vehicle group is empty, the load-bearing vehicle group will continue to move forward until it reaches the second stopper and stops.

[0040] Specifically, after the stopper is opened, the pusher head of the traction chain engages with the lifting claw of the load-carrying vehicle group, and pushes the vehicle group forward along the transportation route through the traction chain. In this process, the front head of the load-carrying vehicle group is at the front end position in the direction of the workpiece movement. When there are no other workpieces or obstacles in front of the load-carrying vehicle group, the load-carrying vehicle group will continue to move forward driven by the traction chain until it reaches the second stopper on the transportation route and stops moving forward due to the second stopper.

[0041] S200. When the subsequent load-bearing vehicle groups enter the entrance section in sequence, under the action of the turnout, the front and rear load-bearing vehicle groups enter the first transverse section and the second transverse section respectively; under the traction of the traction chain, the load-bearing vehicle group located in the first transverse section keeps moving with the traction chain; the second transverse section has a certain oblique angle with the entrance section, so that the load-bearing vehicle group not subjected to traction moves along the component force direction.

[0042] Specifically, when the subsequent load-carrying vehicle groups enter the accumulation area in sequence, the automatic switch machine will divert the load-carrying vehicle groups to the first transverse section and the second transverse section according to the arrangement requirements of the workpieces. The load-carrying vehicle groups in the first transverse section always remain engaged with the traction chain and move forward with the traction chain. The transportation route of the second transverse section forms a certain oblique angle with the entrance section, so that when the traction chain is not directly engaged, the load-carrying vehicle groups can move in the set direction under the action of the oblique angle and the component force, which facilitates the effective distribution of different load-carrying vehicle groups in the transverse section.

[0043] S300, when the working time requirement is met, the second stopper is opened, at which time the front shovel of the front vehicle head sinks, the lifting claw rises, the push head on the rear traction chain engages with the lifting claw, and pushes the load-bearing vehicle group to deliver the workpiece to the exit section; at this time, the third stopper is in a closed state.

[0044] Specifically, when the working time meets the requirements, the second stopper opens, the front shovel on the front head sinks to the bottom of the transport route, and the lifting claw rises at the same time. At this time, the adjacent pusher head on the traction chain engages with the lifting claw, pushing the load-bearing vehicle group with the workpiece forward to the exit section, and stops after reaching the exit section position. At the same time, the third stopper remains closed at this moment to ensure that the load-bearing vehicle group stays at the designated position of the exit section for further operation.

[0045] S400, when the load-carrying vehicle group reaches the third stopper, the front shovel contacts the third stopper, driving the lifting claw to descend, so that the lifting claw is separated from the traction chain push head, and the load-carrying vehicle group stops at the exit section.

[0046] Specifically, when the load-carrying vehicle group reaches the third stopper, the front shovel rises to the inclined surface of the third stopper, and after contacting it, it swings upward, causing the lifting claw to drop and disengage from the pusher head of the traction chain. At this time, the load-carrying vehicle group stops at the third stopper position of the exit section due to the loss of the pushing effect of the traction force, waiting for the next instruction or work station arrangement.

[0047] S500, the traction chain deviates from the exit section at the third stopper and detours from the outside of the exit section. Under the action of the traction chain winding machine, it turns 180° and re-enters the exit section, and contacts the lifting claw on the rear head of the mounting assembly, pushing the mounting assembly to continue moving forward along the exit section.

[0048] Specifically, the third stopper and the automatic plate lifter are respectively located on both sides of the track to ensure the smooth transition and transmission of the load-bearing vehicle group at the exit section.

[0049] When the traction chain reaches the third stopper, it deviates from the exit section track and detours to the outside under the action of the traction chain winding machine. After detour 180°, the traction chain re-enters the exit section track and engages with the lifting claw of the rear head, pushing it forward. Since there is no automatic plate lifter at the junction of the second transverse section and the exit section, the lifting claw of the rear head remains raised, thereby engaging with the pusher, so that the traction chain pushes the entire load-bearing vehicle group to move to the right along the exit section and gradually leaves the area where the automatic plate lifter is located.

[0050] At the same time, the front car head continues to move to the right to the top of the long pallet of the automatic plate lifter. The automatic plate lifter then lifts the long pallet, causing the lifting claw of the front car head to drop to prevent the front car head from engaging with the subsequent pusher head. Before the front car head completely leaves the range of the automatic plate lifter and leaves the exit section, the lifting claw of the front car head is always in a lowered state to ensure that it will not contact the subsequent pusher head. The automatic plate lifter is located on both sides of the junction of the first lateral movement section and the exit section, thereby preventing the front car head and the rear car head from interfering due to the pushers pushing in opposite directions.

[0051] When the front of the vehicle completely leaves the range of the automatic plate lifter, its lifting claw returns to its natural state. At this time, the entire vehicle group moves to the right to the entrance section to complete the transportation of the current workpiece. The automatic plate lifter will then put down the long pallet so that the next vehicle group carrying the workpiece can enter the area under the push of the pusher head and move to the third stopper to stop. The long pallet of the automatic plate lifter rises, and then other vehicle groups follow the above process in turn to complete the entire cycle transmission process.

[0052] In summary, the present application provides a single-chain transverse shifting accumulation device and an operation method, wherein the single-chain transverse shifting accumulation device further comprises: a plurality of load-bearing vehicle groups, wherein the plurality of load-bearing vehicle groups are all slidably arranged on the transport route, wherein the load-bearing vehicle groups are provided with a front head and a rear head arranged at intervals, wherein the front head is provided with a front shovel and a lifting claw connected in rotation, wherein the rear head is provided with a rear shovel, wherein the front head and the rear head form a mounting assembly, wherein the mounting assembly is used to mount workpieces; a traction chain, wherein the traction chain is arranged in the transport route, wherein the traction chain is fixed A pusher head is provided, and the pusher head is used to engage with the lifting claw to push the load-bearing vehicle group to move.

Then, when the load-bearing vehicle group located in the front stops, the front shovel of the load-bearing vehicle group located in the rear will contact the stopped rear shovel of the load-bearing vehicle group located in the front, so that the lifting claw of the load-bearing vehicle group located in the rear is unhooked from the pusher head, avoiding collision and damage of the mounted workpiece, further ensuring the stability of the workpiece during the suspension transportation process, reducing the contact between the workpieces, and effectively improving the safety of the single-chain transverse accumulation device in transporting workpieces.
