Stereoscopic library Also known as elevated warehouse or elevated warehouse, it generally refers to a warehouse that uses several, ten or even dozens of layers of shelves to store unit goods and uses corresponding material handling equipment for warehousing and outbound operations. Because such warehouses can make full use of space to store goods, they are often called "three-dimensional warehouses".
Automatic stereo library (AS/RS) is a revolutionary achievement of logistics technology. It is generally composed of high-rise shelves, lane stackers, conveyors, control systems and computer management systems (WMS). It can complete the automatic storage and retrieval of unit goods under the control of computer systems.
The emergence and development of stereoscopic warehouse is the result of production and technological development after World War II. At the beginning of the 1950s, the three-dimensional warehouse with bridge type stacking crane appeared in the United States; At the end of the 1950s and the beginning of the 1960s, a driver operated three-dimensional warehouse of roadway stacking crane appeared; In 1963, the United States took the lead in adopting computer control technology in the elevated warehouse, and established the first computer controlled three-dimensional warehouse. Since then, automated three-dimensional warehouse has developed rapidly in the United States and Europe, and formed a special discipline. In the mid-1960s, Japan began to build three-dimensional warehouses, and the development speed is getting faster and faster, becoming one of the countries with more automated three-dimensional warehouses in the world today. The development of three-dimensional warehouse and its material handling equipment in China is not late. In 1963, the first bridge stacker crane was developed (Beijing Research Institute of Lifting and Transportation Machinery, Ministry of Machinery). In 1973, the first computer controlled automated three-dimensional warehouse (15m high, in the charge of the Lifting Institute, Ministry of Machinery) was developed. The system was put into operation in 1980. So far (2009), the number of automated three-dimensional warehouses in China has exceeded 1200. Because of its high space utilization rate, strong inbound and outbound capacity, and the use of computers for control management, three-dimensional warehouse has become an indispensable storage technology for enterprise logistics and production management, and has been increasingly valued by enterprises.
