Driving device and driving method of a four-way shuttle trolley

Abstract

The invention relates to a walking device and a walking method for a four-way shuttle trolley, comprising a walking device for a four-way shuttle trolley, which includes a controller for controlling the walking of the four-way shuttle trolley; The track is set sequentially in units of grids, and there is a counting piece in each grid; the counting piece is used to calculate the number of grids that the four-way shuttle trolley runs, and sends the relevant pulse information to the controller; the four-way shuttle trolley also has An RFID reader is provided, and a corresponding RFID chip is provided in each grid of the running track, and the data matching the grid is provided in the RFID chip; the present invention eliminates the The cumulative error of the four-way shuttle car in the process of walking is reduced to make the positioning of the car more accurate; at the same time, an RFID reader and an RFID chip are added to judge whether the number of walking steps of the four-way shuttle car is counted correctly, further increasing the four-way shuttle. The walking accuracy of the trolley.

Description

technical field [0001] The invention belongs to the technical field of a four-way shuttle trolley, and in particular relates to a driving device and a driving method of a four-way shuttle trolley. Background technique [0002] With the advancement of science and technology, modern logistics warehousing is becoming more and more automated. Automated logistics warehousing can save labor intensity and improve work efficiency. The realization of automated logistics warehousing must rely on automated unmanned shuttle cars. The reciprocating handling of goods by the shuttle trolley can realize the transfer of goods very conveniently. [0003] At present, shuttle trolleys generally use four-wheel shuttle trolleys, which are generally used in modern logistics warehouses to shuttle back and forth in the tracks in three-dimensional shelves to carry goods. Its advantage is that the shuttle is fast and convenient, and the operation is relatively stable. The target address of the four-w...

AI Technical Summary

Problems solved by technology

Its advantage is that the shuttle is fast and convenient, and the operation is relatively stable. The target address of the four-way shuttle trolley can be controlled by pulses. And due to various factors such as chains, wheels, tracks, etc., the same pulse will be caused, and the walking distance will deviate. Moreover, when the walking distance is long, the deviation will be relatively large, and the cumulative error will not meet the actual use requirements.
