A method of depositing and retrieving objects

Abstract

The invention provides a goods storing method. A child-mother car is adopted and comprises a mother car, a shifting device, a child car and a jacking device sequentially from bottom to top. The goodsstoring method includes the following steps that firstly, goods are placed on the jacking device, and the mother car runs to a designated position; the shifting device is butted to a rail; then, the jacking device is jacked up, and the child car moves along the butted rail; and finally, a hydraulic platform descends, one time of goods storing is completed, and each device returns to seat sequentially. The invention further provides a goods taking method. Firstly, the mother car runs to the designated position; the shifting device is butted to the rail, the child car moves along the butted rail, then, the jacking device jacks goods up, and finally, the child car, the shifting device and the jacking device return to seat sequentially. The shifting mechanism and the child car system can achieve high precision of goods taking and storing. Compared with a conventional goods taking and storing method such as forking, the system structure is small in displacement and operates more stably whena goods taking system takes the goods.

Description

technical field [0001] The invention relates to the technical field of logistics, in particular to a storage and retrieval method. Background technique [0002] Traditional transportation equipment mainly includes trackless shuttle vehicles (AGV) and rail shuttle vehicles (RGV), but trackless shuttle vehicles are mainly used for the transportation of lighter goods in logistics, and there are no trackless shuttle vehicles for transporting super-large objects. Newspaper: The self-weight of rail shuttle vehicles is generally within 1000kg. Although the load can reach more than 3000kg, the size of the transported objects is within 2m in length and width, which is not suitable for the storage and retrieval of super-large objects. [0003] There is also a mother and child car system for accessing goods. The shuttle trolley moving longitudinally, the mother shuttle trolley moving laterally, and the elevator moving vertically constitute a mother-carriage system with the shuttle tro...

AI Technical Summary

Problems solved by technology

The shuttle trolley moving longitudinally, the mother shuttle trolley moving horizontally, and the elevator moving vertically constitute a mother-carriage system with the shuttle trolley as the core. Although this type of system can access goods more flexibly, it takes a long time to access goods. The average width needs to be controlled within 1.5m, and the load is mostly within 2000kg, which cannot meet the transmission of super-large objects

[0004] Most of the objects that can be accessed by the access equipment in the prior art are within 2m in length and width, and within 3000kg in weight, and it is impossible to access super-large objects
