Description

Technical Field

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

[0002] With the rapid development of artificial intelligence technology, automation technology and information technology, the degree of intelligence of end logistics is also continuously improving, and intelligent warehousing is an important link in the logistics process. In intelligent warehousing, the goods and material conveying system is the main equipment that can realize automatic conveying operations. Through the goods and material conveying system, heavy manual labor of humans can be reduced, and the efficiency of conveying operations, warehousing operations and outbound operations can be improved.

[0003] The Chinese Utility Model Publication Specification CN216174411U discloses a goods conveying system, which relates to the technical field of intelligent warehousing and is used to solve the problem that the space occupied by the goods conveying system is relatively large. The goods conveying system includes a loading and unloading integrated machine, a picking conveyor line and a unloading buffer shelf arranged in sequence along the goods conveying direction; the loading and unloading integrated machine includes a loading and unloading shelf and a picking and placing mechanism arranged on the first side of the loading and unloading shelf, and the picking and placing mechanism is used to move the goods on the loading and unloading shelf out, or move the goods into the loading and unloading shelf; the upstream end of the picking conveyor line is docked with the second side of the loading and unloading shelf so that the goods on the loading and unloading shelf are conveyed onto the picking conveyor line; the unloading buffer shelf is docked with the third side of the loading and unloading shelf so that the goods on the unloading buffer shelf are conveyed onto the loading and unloading shelf;

[0004] The above-mentioned goods conveying system can simultaneously realize the feeding function and the discharging function, so that there is no need to separately set a feeding machine and a discharging machine, which is beneficial to reducing the space occupied by the goods conveying system. However, at present, the conveying of goods or materials generally adopts methods such as conveyor belt conveying, elevator or hoisting for operation. These operations have certain limitations in some special cases. For example, when using a conveyor belt to convey in a position with a small space, the hoisting method is not applicable at this time; for this reason, we provide a material conveying device, which can extend the main body twice and lengthen the conveying distance to make up for the above problems.
