Description

Technical Field

[0001] The invention belongs to the technical field of material storage, and in particular relates to an automatic material storage and conveying system. Background Art

[0002] The raw materials for lithium battery production are mainly foil and powder. After being shipped from suppliers to the production site, the foil and powder are usually unloaded manually. Then the materials are classified and piled on the ground. Before use, they are manually inspected to determine whether the quality is qualified. Finally, the materials are transported by manually operated forklifts for production use.

[0003] Raw materials are piled flat on the ground, resulting in a waste of ground space. The supply of production materials and the recycling of empty pallets require a lot of manual labor, which leads to high labor intensity for workers and easily causes production accidents such as operational errors and material turnover errors. The existence of the above disadvantages reduces the material turnover efficiency of the entire production line and the degree of automation of material turnover, and is not conducive to the company's cost reduction and efficiency improvement.

[0004] The packaging sizes of foil and powder are different. Usually, the wooden pallets for foil and powder are rectangular. The wooden pallets for foil are larger in size. The short side length of the wooden pallet for foil is usually equal to the long side length of the wooden pallet for powder. If foil and powder are stored in the same three-dimensional shelf, it will lead to a waste of cargo space. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the present invention provides an automated material storage and conveying system, which effectively improves the material turnover efficiency and the degree of automation of material turnover, while also improving the utilization rate of storage space, reducing the error rate and accident rate during material turnover, reducing the labor intensity of workers, and at the same time reducing production costs.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an automated material storage and conveying system, comprising: a front-end conveying unit, used to transfer the materials to be stored to the storage unit; also used to receive empty pallets sent by the storage unit, and the empty pallets are used to hold the materials to be stored; the storage unit is used to store the materials to be stored sent by the front-end conveying unit, the empty pallets sent by the rear-end conveying unit, and the empty pallets sent by the return conveying unit into the shelves respectively; it is also used to transfer the materials stored in the shelves to the rear-end conveying unit, and transfer the empty pallets stored in the shelves to the front-end conveying unit; it is also used to transfer the unqualified materials stored in the shelves to the return conveying unit; the rear-end conveying unit is used to transfer the materials sent by the storage unit to the production process; it is also used to transfer the empty pallets sent by the production process to the storage unit; the return conveying unit is used to transfer the unqualified materials sent by the storage unit to the return area; it is also used to transfer the empty pallets in the return area to the storage unit.

[0007] The above technical scheme, by setting up a front-end conveying unit, an in-and-out storage unit, a rear-end conveying unit and a return conveying unit, and rationally planning the functions of each conveying unit, effectively improves the material turnover efficiency and the degree of automation of material turnover.

[0018] Furthermore, when the information acquisition module 2 recognizes that the material to be stored in the pallet is the second type of material, the storage-in and storage-out unit sends the second type of material to the storage-in lifting machine 3 through the roller conveyor line 3, the turntable 5, and the roller conveyor line 6, and stores it in the shelf 2 through the stacker 2; when the production process needs to use the second type of material, the storage-in and storage-out unit transfers the second type of material in the shelf 2 to the storage-in lifting machine 4 through the stacker 2, and sends it to the rear-stage conveying unit through the roller conveyor line 7, the turntable 6, and the roller conveyor line 3; when the information acquisition module 3 recognizes that the empty pallet sent by the rear-stage conveying unit is used to store the second type of material, the empty pallet is sent to the storage-in lifting machine 4 through the roller conveyor line 3, the turntable 6, and the roller conveyor line 7, and stores it in the shelf 2 through the stacker 2; when there is a second type of material that needs to be stored, the storage-in and storage-out unit transfers the empty pallet in the shelf 2 to the storage-in lifting machine 3 through the stacker 2, and sends it to the front-stage conveying unit through the roller conveyor line 6, the turntable 5, and the roller conveyor line 3.
