Abstract: The number of express package is huge.The appearance of express package is similar.It causes the problems of low storage and access operation efficiency and the high handling cost.Especially for large shelves,courier access to goods and find the goods is very inconvenient.An intelligent express storage and access system is proposed and designed from changing the mode of original express storage and access.Considering the adaptability and extensibility,modular design is used to the structure design of an intelligent express storage and access system.Physical model and movement result show that the proposed system can achieve automatic express package storage and access,improving storage and access operation efficiency,reducing the labor intensity during express package storage and access.

Key words: express, automatic storage and access, modular design
