Modular circulating grid-based storage system and dispatching method

Abstract

The invention discloses a modular circulating grid-based storage system and a dispatching method. The modular circulating grid-based storage system comprises a picking area and a stocking area, The picking area comprises m picking modules, and each picking module comprises a plurality of goods grids. The goods grid at the outermost end of each picking module is a picking position, and the pickingposition is connected with an external picking device. The stocking area comprises a stocking module, and the stocking module comprises a plurality of goods grids. At least one goods grid in each picking module is connected with the goods grids in the stocking module, and the goods grids connected between the picking modules and the stocking module are respective connector positions. Each pickingmodule is internally provided with at least two vacant goods grids, and the stocking module is internally provided with at least two vacant goods grids. The modular circulating grid-based storage system is formed by connecting multiple modularized grid storage modules and has high flexibility and expansibility. A decoupled distributed type dispatching control architecture is adopted, so that flexible transferring of the whole storage system and the order picking work of multiple picking points are realized.

Description

technical field [0001] The invention belongs to the technical field of automated storage systems, and in particular relates to a modular circulation grid type storage system and a dispatching method. Background technique [0002] The automatic storage system is an important part of the modern logistics system. The main function of the automatic storage system is to dispatch goods in and out of the warehouse according to the order requirements. Grid-based storage system (Grid-based Storage System, GBSSystem) is a new type of storage system that has emerged in the past ten years. It is composed of rectangular storage units closely arranged, and each storage unit is loaded or empty. The load can be moved from one compartment to the adjacent empty space, such as figure 1 shown. Compared with the traditional automated three-dimensional warehouse (AS / RS), the grid-type storage system cancels the space occupied by the aisle, has the characteristics of high storage density, easy i...
