[0001] This utility model relates to the field of cargo transportation technology, and in particular to a rack docking device that works in conjunction with an AGV (Automated Guided Vehicle) trolley. Background Technology

[0002] In the field of modern logistics and warehousing automation, AGVs (Automated Guided Vehicles) have become core equipment in intelligent warehousing systems due to their efficient and precise material handling capabilities. However, when AGVs dock with shelves to handle goods, traditional operating methods present significant efficiency bottlenecks.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the existing technology, the docking of the shelves and AGV carts mostly relies on manual operation. The staff needs to wait for the AGV cart to arrive at the designated position and then manually move the shelves from the storage area to the cart. This not only consumes a lot of manpower and time, but is also prone to problems such as shelves tipping over and goods being damaged due to human error. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the existing technology, workers need to wait for the AGV cart to arrive at the designated position and then manually move the shelves from the storage area to the cart. This not only consumes a lot of manpower and time, but also easily leads to the shelves tipping over and goods being damaged due to human error. Therefore, we propose a shelf docking device that works in coordination with the AGV cart.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rack docking device for collaborative operation with an AGV trolley, comprising a support plate, a support frame fixedly connected to the upper surface of the support plate, two slide rods slidably inserted inside the support plate, a push plate fixedly connected to one end of the two slide rods, a connecting plate fixedly connected to the end of the two slide rods away from the push plate, a strip plate fixedly connected to the upper surface of the connecting plate, a support plate fixedly connected to one side of the strip plate, a sliding groove provided on one side of the support frame, the surface of the sliding groove of the support frame slidably connected to the support plate, a first spring sleeved on the arc surface of the slide rod, and the two ends of the first spring fixedly connected to the connecting plate and the support plate respectively.

A fixing rod is fixedly connected to one side of the slide rail, and an operating plate is slidably connected to the arc surface of the fixing rod. An insertion rod is fixedly connected to one side of the operating plate, and several insertion holes are opened on the surface of the baffle plate.

[0010] Preferably, one end of the fixing rod is fixedly connected to a limiting plate, and the size of the insertion rod is adapted to the size of the insertion hole of the blocking plate.

[0011] Preferably, a second spring is fitted onto the arc surface of the fixing rod, and the two ends of the second spring are fixedly connected to the operating plate and the slide rail, respectively.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the combined use of the push plate, the support plate, and the first spring achieves the effect of facilitating the automatic docking and transfer of goods between the trolley and the small shelf.

Detailed Implementation

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figure 1-5As shown, this utility model provides a technical solution: a shelf docking device for collaborative operation with an AGV trolley, including a support plate 1, a support frame 2 fixedly connected to the upper surface of the support plate 1, two sliding rods 3 slidably inserted inside the support plate 1, a push plate 4 fixedly connected to one end of the two sliding rods 3, a connecting plate 5 fixedly connected to the end of the two sliding rods 3 away from the push plate 4, a strip plate 6 fixedly connected to the upper surface of the connecting plate 5, a support plate 7 fixedly connected to one side of the strip plate 6, a sliding groove opened on one side of the support frame 2, the surface of the sliding groove of the support frame 2 slidably connected to the support plate 7, a first spring 8 sleeved on the arc surface of the sliding rod 3, the two ends of the first spring 8 being fixedly connected to the connecting plate 5 and the support plate 1 respectively, when the trolley is about to dock with the small shelf on the support plate 7, the trolley moves backward. The pusher plate 4 moves, causing the slide bar 3 to slide within the support plate 1. Simultaneously, the first spring 8 is stretched, causing the slide bar 3 to move the connecting plate 5. The connecting plate 5 then moves the strip plate 6, which in turn moves the support plate 7 within the sliding groove of the support frame 2. At this point, the small shelves on the support plate 7 gradually separate and fall onto the trolley. The trolley then begins to move away, and the rebound force of the first spring 8 causes the support plate 7 to return to its original position, supporting the high-level small shelves. This achieves the effect of convenient automatic docking and transfer of goods between the trolley and the small shelves, avoiding the need for workers to wait for the trolley to reach its target location and manually place the small shelves onto it when transferring shelves via trolley docking, which wastes a significant amount of work time and reduces worker efficiency. To address the issue of uneven loading and improve the practicality of the device, several rotating grooves are provided on the surface of the pallet 7. Ball bearings 9 are rotatably connected to the surface of these grooves, facilitating the rapid transfer of small shelves from the pallet 7 to the trolley. This prevents jamming between the pallet 7 and the small shelf, which could cause the small shelf to fail to land at its designated position on the trolley, thus affecting its stability. A fixing plate 11 is fixedly connected to the surface of the support frame 2. A drive rod 12 is threaded into the fixing plate 11, and one end of the drive rod 12 is rotatably connected to a guide frame 13. This provides vertical guidance for small shelves of different sizes, preventing the lower shelf from tilting after being transported by the trolley, and minimizing the tilt after multiple transports. If the size is too large, it may affect transportation. A positioning rod 14 is fixedly connected to one side of the guide frame 13. The arc surface of the positioning rod 14 is slidably connected to the fixed plate 11. The positioning rod 14 restricts the rotation of the guide frame 13 following the drive rod 12, thus providing accurate guidance for the guide frame 13. Two slide rails 15 are fixedly connected to the upper surface of the support frame 2. A blocking plate 16 is slidably connected within the two slide rails 15. A fixing rod 17 is fixedly connected to one side of the slide rail 15. An operating plate 18 is slidably connected to the arc surface of the fixing rod 17. An insertion rod 19 is fixedly connected to one side of the operating plate 18. Several insertion holes are provided on the surface of the blocking plate 16, achieving the effect of blocking taller shelves and preventing excessive tilting angle when small shelves slide into the trolley surface.To prevent the upper shelf from tipping over, a limiting plate 20 is fixedly connected to one end of the fixing rod 17. The size of the insertion rod 19 matches the size of the insertion hole in the blocking plate 16, thus limiting the maximum sliding distance of the operating plate 18 on the arc surface of the fixing rod 17. This prevents the operating plate 18 from detaching from the arc surface of the fixing rod 17 due to excessive pulling force when pulled by the operator. A second spring 21 is fitted onto the arc surface of the fixing rod 17, with both ends of the second spring 21 fixedly connected to the operating plate 18 and the slide rail 15, respectively. The second spring 21 improves the stability of the insertion rod 19 when limiting the blocking plate 16.

[0023] Working principle: When the AGV trolley is ready to dock with the small shelf on pallet 7, the trolley moves backward and pushes the push plate 4. The push plate 4 drives the slide rod 3 to slide within the support plate 1, stretching the first spring 8. At the same time, the slide rod 3 drives the pallet 7 to slide within the sliding groove of the support frame 2 through the connecting plate 5 and the strip plate 6, causing the small shelf on pallet 7 to gradually separate and fall onto the trolley. After the trolley leaves, the rebound force of the first spring 8 causes the pallet 7 to return to its original position, supporting the high-level small shelf and realizing automatic docking and transfer. The ball bearings 9 on the surface of pallet 7 can reduce friction with the small shelf, ensuring that the small shelf slides smoothly into the designated position of the trolley. Rotating the drive rod 12 inside the fixed plate 11, the drive rod 12... The guide rod 14 guides the guide frame 13 to move, which can guide small shelves of different sizes and prevent the small shelves above from tilting. When it is necessary to adjust the position of the blocking plate 16, the operating plate 18 is pulled to overcome the elastic force of the second spring 21, so that the insertion rod 19 is pulled out from the insertion hole of the blocking plate 16. After the blocking plate 16 is slid in the slide rail 15 to the appropriate position, the operating plate 18 is released, and the second spring 21 returns to its original position, which drives the insertion rod 19 to insert into the insertion hole and fix it. The blocking plate 16 can prevent the small shelf from tilting too much when it slides into the trolley and causing it to tip over. The whole device realizes the automatic docking of the AGV trolley and the shelf through the combination of spring drive and mechanical limit, which improves the efficiency of cargo transfer.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
