Description

Technical Field

[0001] The utility model relates to the technical field of intelligent distribution of automobile parts, in particular to a decoupling device for a packing vehicle. Background Technique

[0002] An automated guided vehicle (AGV) is a transport vehicle equipped with an automatic guidance device such as electromagnetic or optical, capable of traveling along a specified guidance path, having safety protection and various transfer functions. AGVs belong to the category of wheeled mobile robots.

[0003] On the production line, AGVs are often used to tow several packing vehicles equipped with parts from the warehouse to the side of the production line for distribution. The commonly used method at present is: the packing vehicles are connected by hooks, and manual operation is required to engage the hooks. The decoupling of the packing vehicles is also manually operated, resulting in high labor intensity and low efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a decoupling device for a packing vehicle to solve the problems of high labor intensity and low efficiency in the existing manual decoupling of packing vehicles.

[0005] To achieve the above object, the basic scheme of the utility model is as follows: A decoupling device for a packing vehicle, including a front decoupling component and a rear decoupling component. The front decoupling component and the rear decoupling component are respectively installed at the front and rear ends of the packing vehicle. The front decoupling component and the rear decoupling component both include a mounting seat, a collision rod, and an elastic return member. The collision rod is L-shaped. One end of the collision rod is rotatably connected to the mounting seat, and the other end of the collision rod extends beyond the edge of the packing vehicle. The elastic return member is installed between the collision rod and the mounting seat for the return of the collision rod. The front decoupling component further includes a rotating shaft, a hook shaft, and a blocking plate. The rotating shaft is fixed to the mounting seat of the front decoupling component. The hook shaft is rotatably connected to the rotating shaft. An elastic member is provided between the hook shaft and the rotating shaft for the return of the hook shaft. The blocking plate is located at the top of the hook shaft. The blocking plate is fixedly connected to the collision rod. A U-shaped groove is provided at the end of the blocking plate, and the U-shaped groove abuts against the top of the hook shaft. The rear decoupling component further includes a hanging plate, a hanging ring, a locking plate, and a pressing plate. The hanging ring is fixed to the top of the hanging plate. The bottom of the hanging plate is rotatably connected to the mounting seat of the rear decoupling component. An elastic member is provided between the hanging plate and the mounting seat. The locking plate is fixedly connected to the collision rod of the rear decoupling component. The pressing plate is fixedly connected to the side of the hanging plate, and the pressing plate is closely attached to the upper end face of the locking plate.

[0006] Further, the front decoupling component and the rear decoupling component further include a rotating wheel, and the rotating wheel is rotatably connected to the end of the collision rod located outside the packing vehicle.

[0007] Furthermore, the front decoupling hook assembly further includes a limit block, which is fixed on the mounting seat of the front decoupling hook assembly. A strip-shaped hole is provided in the middle of the limit block, and the bottom of the hook shaft is located in the strip-shaped hole.

[0008] Furthermore, both the elastic return member and the elastic member are disc springs.

[0009] Beneficial effects of this solution: (1) Collision piles are provided on the side of the track at the loading and unloading positions. When the packing vehicle needs to hook up with the vehicle in front, the lower part of the hook shaft of the front decoupling hook assembly hits the hook of the vehicle in front. The hook shaft rotates along the rotating shaft until the hook shaft is inserted into the hook ring of the vehicle in front. After the hook shaft of the front decoupling hook assembly is inserted into the hook ring, the hook shaft returns to its original position under the restoring force of the elastic member, and the blocking plate restricts the reverse rotation of the hook shaft, thus locking the hook shaft in the hook ring to achieve automatic hooking; when there is another packing vehicle that needs to be connected behind this packing vehicle when it reaches the predetermined position, the collision rod of the rear decoupling hook assembly collides with the collision pile on the side of the track. As the packing vehicle continues to move forward, the collision pile drives the collision rod of the rear decoupling hook assembly to rotate. The rotation of the collision rod of the rear decoupling hook assembly drives the lock catch plate to flip, and the lock catch plate flips to drive the pressure plate above the lock catch plate, thereby driving the hanging plate and the hanging ring to move downward, so that the hanging ring is directly opposite to the packing vehicle behind. The front decoupling hook assembly of the packing vehicle behind is buckled into the hanging ring through the above method to complete the hanging. When the packing vehicle reaches the unloading position and needs to unload, the end of the collision rod of the front decoupling hook assembly touches the collision pile, and under the action of the collision pile, the end of the collision rod rotates backward, causing the blocking block on the collision rod to flip. The blocking block no longer limits the hook shaft after flipping, and the hook shaft can rotate in the reverse direction. The vehicle in front can move forward to unhook from the front decoupling hook assembly of the vehicle behind, realizing automatic hooking and unhooking, replacing manual operation, saving labor and improving efficiency at the same time.

[0010] (2) The rotating wheel at the end of the collision rod facilitates the collision column to push the collision rod to rotate. Description of the Drawings

[0016] Embodiment

[0017] Basically as shown in the attached Figure 1 figures: A decoupling hook device for a packing cart includes a front decoupling hook assembly 1 and a rear decoupling hook assembly 2. The front decoupling hook assembly 1 and the rear decoupling hook assembly 2 are respectively installed at the front and rear ends of the packing cart 3. Combining Figure 2 、 Figure 3 as shown, both the front decoupling hook assembly 1 and the rear decoupling hook assembly 2 include a mounting seat 4, a collision rod 5, an elastic return member, and a rotating wheel 6. The collision rod 5 is L-shaped. One end of the collision rod 5 is rotatably connected to the mounting seat 4, and the other end of the collision rod 5 extends beyond the edge of the packing cart 3. The rotating wheel 6 is rotatably connected to the end of the collision rod 5 located outside the packing cart 3. The elastic return member is installed between the collision rod 5 and the mounting seat 4 for the collision rod 5 to return. The front decoupling hook assembly 1 further includes a rotating shaft 7, a hook shaft 8, a blocking plate 9, and a limiting block 10. The rotating shaft 7 is fixed to the mounting seat 4 of the front decoupling hook assembly 1. The hook shaft 8 is rotatably connected to the rotating shaft 7. An elastic member is provided between the hook shaft 8 and the rotating shaft 7 for the hook shaft 8 to return. The blocking plate 9 is located at the top of the hook shaft 8. The blocking plate 9 is fixedly connected to the collision rod 5. A U-shaped groove is provided at the end of the blocking plate 9, and the U-shaped groove abuts against the top of the hook shaft 8. The limiting block 10 is fixed to the mounting seat 4 of the front decoupling hook assembly 1. A strip-shaped hole is provided in the middle of the limiting block 10, and the bottom of the hook shaft 8 is located in the strip-shaped hole. The rear decoupling hook assembly 2 further includes a hanging plate 11, a hanging ring 12, a lock catch plate 13, and a pressing plate 14. The hanging ring 12 is fixed to the top of the hanging plate 11. The bottom of the hanging plate 11 is rotatably connected to the mounting seat 4 of the rear decoupling hook assembly 2. An elastic member is provided between the hanging plate 11 and the mounting seat 4. The lock catch plate 13 is fixedly connected to the collision rod 5 of the rear decoupling hook assembly 2. The pressing plate 14 is fixedly connected to the side of the hanging plate 11, and the pressing plate 14 closely abuts against the upper end surface of the lock catch plate 13. The elastic return member and the elastic member are both butterfly springs (the elastic return member and the elastic member are not shown in the figure).

[0018] The specific implementation process is as follows: Collision piles are set beside the tracks at the loading and unloading positions. When the packing vehicle 3 needs to hook up with the vehicle in front, the lower part of the hook shaft 8 of the front decoupling hook assembly 1 impacts the hook of the vehicle in front. The hook shaft 8 rotates along the rotating shaft 7 until the hook shaft 8 is inserted into the hook ring of the vehicle in front. After the hook shaft 8 of the front decoupling hook assembly 1 is inserted into the hook ring, the hook shaft 8 returns to its original position under the restoring force of the elastic member, and the blocking plate 9 restricts the reverse rotation of the hook shaft 8, thereby locking the hook shaft 8 in the hook ring to achieve automatic hooking. When there is another packing vehicle 3 that needs to be connected behind the packing vehicle 3 after it reaches the predetermined position, the collision rod 5 of the rear decoupling hook assembly 2 collides with the collision pile beside the track. As the packing vehicle 3 continues to move forward, the collision pile drives the collision rod 5 of the rear decoupling hook assembly 2 to rotate. The rotation of the collision rod 5 of the rear decoupling hook assembly 2 drives the lock catch plate 13 to flip, and the lock catch plate 13 flips to drive the pressing plate 14 above the lock catch plate 13, thereby driving the hanging plate 11 and the hanging ring 12 to move downward, so that the hanging ring 12 is facing the packing vehicle 3 behind. The front decoupling hook assembly 1 of the packing vehicle 3 behind is buckled into the hanging ring 12 in the above manner to complete the connection. When the packing vehicle 3 reaches the unloading position and needs to unload, the end of the collision rod 5 of the front decoupling hook assembly 1 touches the collision pile, and under the action of the collision pile, the end of the collision rod 5 rotates backward, causing the blocking block on the collision rod 5 to flip. The blocking block no longer limits the hook shaft 8 after flipping, and the hook shaft 8 can rotate in the reverse direction. The vehicle in front can move forward to unhook from the front decoupling hook assembly 1 of the vehicle behind, realizing automatic hooking and unhooking, replacing manual operation, saving labor and improving efficiency at the same time.
