Description

Technical Field

[0001] The present invention relates to the technical field of storage shelves, and in particular to a logistics storage shelf and a use method thereof. Background Art

[0002] Logistics storage shelves are equipment used to store and manage goods in modern logistics storage systems. There are many types of logistics storage shelves. Beam shelves are a common type of shelves, which are composed of columns and beams. In the current beam shelf storage system, the platform of each layer lacks an effective limit device. Therefore, when using a forklift to put goods on the shelves, the goods may not be placed accurately. This situation not only increases the risk of collision between the goods and the forklift, affecting the operation of the forklift, but also may cause the goods to be knocked down by the forklift, posing a threat to the storage safety of the goods. In addition, the existing shelf layout allows the forklift to only load and unload the left and right rows of shelves in a single shelf aisle, which limits the operating efficiency of the forklift. In order to meet the operating needs of the forklift in a warehouse, more shelf aisle space must be reserved, which directly affects the space utilization of the warehouse. If you want to load and unload multiple shelves at the same time, you need to deploy multiple forklifts, which not only increases the complexity of warehousing operations, but also increases costs.

[0003] The patent application document with publication number CN116573326A discloses an adjustable storage shelf for warehousing and logistics, which specifically includes: a fixed box, the outside of which is fixedly connected with a positioning mechanism; a lifting mechanism, which is used to fix the position of the goods and drive the goods to be lifted and lowered, and the lifting mechanism includes an electric telescopic column, the top of which is fixedly connected with a lifting box, and the electric telescopic column is fixedly connected to the inside of the positioning mechanism; and an adjustment mechanism includes an arc-shaped shell. The adjustable storage shelf for warehousing and logistics is provided with a pushing component. When the lifting mechanism transports the goods to the bottom plate, the pushing mechanism is turned on to push the goods to the left and right sides. However, when the goods arrive on the shelf, it is easy to fail to push them into place or the thrust is too large, resulting in the goods not being neatly placed on the shelf. Therefore, it is necessary to develop a logistics storage shelf to solve the technical problem that only one row of pallets can be placed on each shelf and the pallets cannot be sorted. Summary of the invention

[0004] In view of this, the present invention provides a logistics storage shelf and a method of using the same, aiming to solve the technical problem in the prior art that each shelf layer can only hold one row of pallets and the pallets cannot be sorted.

[0005] In order to solve the above technical problems, the present invention provides a logistics storage shelf, comprising a column, a beam fixedly connected to the column, and a placement platform arranged on the beam, wherein the placement platform is rotatably connected to a plurality of conveying rollers capable of conveying pallets; a portion of the placement platform is provided with a mobile frame, wherein the mobile frame comprises a mobile frame, a support rod fixedly connected in the mobile frame and parallel to the beam, and the mobile frame is elastically connected to the placement platform;

[0007] By adopting the above technical solution, when the forklift's fork drives the pallet to move to the mobile rack, the mobile rack moves down, and the positioning plate arranges the pallet. When it is necessary to continue to place the pallet, the fork presses down the mobile rack so that the support rod is lower than the conveying roller, and the conveying roller is started to transport the pallet to the other end, and then the pallet can be placed at this position. One row of pallets or two rows of pallets can be placed on each shelf of the present invention, which increases the utilization space of the shelf and improves the operating efficiency of the forklift. After the pallet is placed, the positioning plate can arrange the pallet so that the pallet can be neatly placed in place.

[0016] Preferably, a limiting rod for limiting the position of the pallet is provided on one end of the cross beam away from the movable frame.

[0017] By adopting the above technical solution, when the conveying roller conveys the pallet, the limiting rod can limit the pallet so that the pallet can be placed in place.

[0018] Preferably, a mounting hole is provided on the column, a connecting piece is fixedly connected to the end of the placement platform, and a fixing claw that can be inserted into the mounting hole is fixedly connected to the connecting piece.

[0019] By adopting the above technical solution, the connecting piece is connected to the mounting hole through the fixing claw. A plurality of mounting holes are provided, and the distance between the upper and lower placing platforms can be adjusted to facilitate the storage of goods of different heights.

[0020] Preferably, the method of using the logistics storage shelf comprises the following steps:

[0021] Step S1: When there is only one pallet on the shelf, the forklift's fork drives the pallet to move to the mobile rack, the mobile rack moves down, the spring is compressed, the end face of the support rod is flush with the end face of the conveyor roller, and the pallet is supported together. At the same time, the connecting column on the mobile rack moves down, driving the positioning plates on both sides to slide toward the middle through the curved hole, the pallet is sorted, and then the fork is taken out;

[0022] Step S2: When two pallets need to be placed on the shelf, follow the above step S1. After the positioning plate arranges the pallets, the forklift drives the fork to move downward, the mobile rack continues to descend, the mobile rack is separated from the pallet, the connecting column moves downward, the positioning plate slides to both sides, the motor is started, and the conveyor roller conveys the pallet to the end of the placement platform away from the mobile rack. The motor stops rotating, and step S1 is repeated to transfer the pallet to the mobile rack.

[0023] By adopting the above technical solution, one row of pallets or two rows of pallets can be placed on each shelf, which increases the utilization space of the shelf and improves the operating efficiency of the forklift. After the pallets are placed, the positioning plates can organize the pallets so that the pallets can be neatly placed in place.

[0024] The beneficial effects of the above technical solution of the present invention are as follows:

[0025] 1. One row of pallets or two rows of pallets can be placed on each shelf of the present invention, which increases the utilization space of the shelf and improves the operating efficiency of the forklift. After the pallets are placed, the positioning plates can arrange the pallets so that the pallets can be neatly placed in place.

[0026] 2. When the fork of the present invention drives the pallet to move onto the mobile frame, the mobile frame descends, the connecting column descends, and the curved hole drives the positioning plate to move toward the middle, so that the positioning plate can arrange the pallet.
