Shuttle vehicle control method and device

Abstract

The invention discloses a shuttle vehicle control method and device, and relates to the technical field of warehouse logistics. The shuttle vehicle control method comprises the following steps: afterreceiving a task instruction, judging a task type according to a task type identifier carried by the task instruction; when the task type is a goods taking task, determining a first variable-pitch width corresponding to the goods taking task, so as to control a variable-pitch mechanism to adjust the distance between two fork arms on the shuttle vehicle according to the first variable-pitch width when a material box is taken; and when the task type is a delivery task, determining a second variable-pitch width corresponding to the delivery task so as to control the variable-pitch mechanism to adjust the distance between the two fork arms on the shuttle vehicle according to the second variable-pitch width when the material box is placed. Through the steps, the box collision risk of the shuttle vehicle in the material box taking process can be reduced, and the safety of the shuttle vehicle for taking and delivering the material box is improved.

Description

technical field [0001] The invention relates to the technical field of warehousing and logistics, in particular to a method and device for controlling a shuttle. Background technique [0002] In the three-dimensional warehouse, the shuttle car is an important handling equipment for picking up and delivering goods. When the shuttle car takes out the material box from the storage position and then puts the material box back into the storage position again, the position of the material box on the storage position is prone to shift. When the position deviation is large, it is easy to cause a box collision when the shuttle car picks up the box again. [0003] In order to solve this problem, the existing shuttle car is provided with a mechanical guide mechanism on the vehicle body. After the material box is pulled back to the inside of the car body by the fork on the shuttle car, the material box can be forced to return through the mechanical guide mechanism, so when the materia...

AI Technical Summary

Problems solved by technology

However, when discharging the material box, since there is no guide on the outside of the vehicle body, the material box may be offset when sliding on the outside of the vehicle body, which will cause the material box to shift on the storage position

When the offset is large, a box collision may also occur when the shuttle car picks up the box again

Second, when the positioning accuracy of the car body is poor, even if there is a mechanical guide mechanism in the body of the shuttle car, the poor positioning accuracy of the car body may cause a position shift when sending out the material box, and then there will be a collision when the material box is taken out again. box risk
