Shuttle

Abstract

The invention provides a shuttle comprising a frame and a travelling mechanism fixed on the frame. The shuttle further comprises a traction mechanism disposed on the frame. The traction mechanism comprises an actuator arranged above the frame and a drive mechanism which drives the actuator to operate. The actuator comprises a first sprocket, a second sprocket, a first chain, and traction pins; the first sprocket fixed on the frame is driven by the drive mechanism; the second sprocket faces the first sprocket; the first sprocket and the second sprocket are in meshed connection through the first chain; the traction pins are fixed on the first chain. The shuttle is simple in structure, high in goods handling efficiency, convenient to manufacture and low in cost.

Description

technical field [0001] The invention relates to a transportation device of a warehouse logistics system, in particular to a shuttle car used in storage and retrieval of goods in a three-dimensional warehouse. Background technique [0002] At present, the storage and withdrawal of heavy goods in the three-dimensional warehouse is usually completed by using the roadway stacker. This kind of roadway type stacker has strong bearing capacity and fast single machine operation speed. However, since there are at most two stackers arranged in a single lane, the frequency of access to goods by the stacker is limited. For medium and light cargo, the storage and withdrawal in the form of shuttle vehicles are gradually beginning to be adopted. The use of shuttle vehicles to access goods can realize multi-vehicle and layered access in a single lane, which greatly improves the efficiency of warehouse entry and exit, and can flexibly configure shuttle vehicles according to warehouses, thu...

AI Technical Summary

Problems solved by technology

However, this kind of shuttle car needs to lay the running track under the goods, so that the storage and retrieval process of the shuttle car must abide by the principle of first-in-last-out or first-in-first-out on the one hand, and the goods in the middle cannot be taken out, which is not flexible enough; on the other hand, the shuttle Cars occupy the height space of the shelf, resulting in low space utilization in the height direction of the shelf; in addition, the distance in the traveling direction of the shelf using this kind of shuttle car should not be too large, and three or more shuttle cars cannot be operated at the same time in the same cargo lane
