Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, and more specifically, to a material conveying trolley. Background Art

[0002] In modern production, AGV material conveying carts are widely used in various industries because they can realize the function of automatically conveying materials. Especially in pharmaceutical warehouses, the use of AGV material conveying carts to automatically transport pharmaceutical materials can greatly reduce the problem of pharmaceutical material distribution errors caused by human handling errors, and also keep pharmaceutical materials clean and free from contamination during the transportation process, which increases the safety and accuracy of pharmaceutical transportation to a certain extent. In existing pharmaceutical warehouses, medicines are generally placed in pharmaceutical material boxes, and material racks with multi-layer storage space are used to store pharmaceutical materials. Ordinary AGV material conveying carts only have the function of simply moving and conveying materials, but do not have the function of taking materials out from high-level material racks, and their use in warehouses is relatively limited. In order to meet the material transportation needs of this type of warehouse, storage robots have appeared on the market. Storage robots are AGV material transportation carts used in warehouses, which have the function of picking up and placing materials from high-level material racks. This type of robot moves automatically through the bottom moving component, and picks up and places materials through the lifting component and the clamping component set on the lifting component. However, when picking up and placing materials, this type of robot can only take out and put back a single layer of materials in turn through the lifting component, and cannot directly take out multiple layers of materials from the material rack at one time, so the work efficiency is low.

[0043] The driving assembly drives the transmission assembly, and the transmission assembly drives the side plate 401 and the baffle 402 to move back and forth together, and the baffle 402 pushes the material from the carrier 3 during the movement. Further, a chute is provided on the inner side of the carrier 3, and the side plate 401 is arranged in the chute. The depth of the chute is consistent with the thickness of the side plate 401, that is, the surface of the side plate 401 is flush with the inner side of the carrier 3.

A roller member 6 is provided to assist the sliding of the material. When the material is pushed out or brought back to the carrier 3, it will first pass through the roller. A roller member 6 is provided on the side of each carrier 3. At the same time, the roller member 6 uses the rotating shaft 404 as the rotation axis to further utilize the rotating shaft 404, and adds the function of reducing friction at a lower cost. Specifically, the top of the side of the roller is flush with the working surface of the carrier 3. Side plates 401 are respectively provided on both sides of the carrier 3, and each side plate 401 is driven by a driving assembly.

[0050] The protective shell 7 is used to protect the transmission component from external dust or impurities, and also improves the appearance of the equipment. A blocking member 502 is installed on the rotating end of the driving member 501. The driving member 501 drives the blocking member 502 to rotate out or rotate back. When the telescopic component 4 is extended, the blocking member 502 rotates out to block the material. When the telescopic component 4 is retracted, the blocking member 502 moves with the material, and then moves the material to the carrier 3. The slot portion 4011 is used to prevent the blocking member 502 from rotating excessively, and also enhances the working strength of the blocking member 502. When the blocking member 502 moves with the material, the slot portion 4011 can block the blocking member 502 to prevent the blocking member 502 from deformation.

[0051] Specifically, in this embodiment, the first transmission wheel 403 and the second transmission wheel 405 are sprockets, and the transmission member 406 is a chain.
