Locking and releasing device of transmission shaft for automatic goods shelf

Abstract

The invention relates to a locking and releasing device of a transmission shaft for an automatic goods shelf. The locking and releasing device comprises the goods shelf, wherein the transmission shaft is arranged on the goods shelf. The locking and releasing device is characterized in that a bracket rod is arranged on the goods shelf on the lower side of the transmission shaft; the bracket rod is parallel to the transmission shaft; levers are hinged to the bracket rod; gears are fixed in the positions, corresponding to the levers, of the transmission shaft; racks are arranged in the positions, below the gears, of the levers; when the gravity centers of the levers are positioned on the side, away from the transmission shaft, of the bracket rod, the gears on the transmission shaft mesh with the racks on the levers through the gravity action of the levers; when the gravity centers of the levers are positioned on the side, close to the transmission shaft, of the bracket rod, an extension spring is connected between the ends, away from the transmission shaft, of the levers and the goods shelf below the levers, and the gears on the transmission shaft mesh with the racks on the levers through the tension action of the extension spring. According to the device, the transmission shaft of the automatic goods shelf can be effectively locked, goods are prevented from moving or sliding, the structure is simple, the mounting space is small, the processing cost is low, and the automation requirement can be met.

Description

technical field [0001] The invention relates to an automatic shelf, in particular to a drive shaft locking and releasing device for the automatic shelf, and is especially suitable for the storage position along the track of the conveyor belt or conveyor chain type automatic shelf. Background technique [0002] With the development of science and technology, automated shelves are widely used in storage and transportation. The most typical structure of the automated shelf is the conveyor belt or conveyor chain structure, that is, the drive mechanism is used to drive the transmission shaft to rotate, so as to drive the conveyor belt or conveyor chain to transport the goods to the corresponding position of the shelf, so as to realize the purpose of goods storage and transportation. [0003] However, in the process of storage or transportation of goods, it is inevitable that the shelf will be tilted due to the slope of the ground. In this case, the goods can easily drive the c...

AI Technical Summary

Problems solved by technology

Although this device can realize the shaft locking function when the shelf is tilted to prevent the goods from shifting or slipping out, its structure is complicated, the installation space is large, and the processing cost is high. At the same time, manual operation of the chain and bolts is required, which is time-consuming and laborious. automation requirements
