The first stage
The material conveying, storage, management and control mainly depend on manual implementation, real-time and intuition are obvious advantages. Artificial storage technology also has the superiority in the initial equipment investment and economic index.
The second stage
The material can be through a variety of transmission belt, industrial transport vehicles, mechanical hand, cranes, stacking machine and lift to move and transport, with a pallet rack and a movable rack storage of materials, through the manual operation with mechanical access device, limit switch, the spiral mechanical braking and mechanical monitor and control the operation of equipment. Mechanization to meet people's speed, precision, height, weight, repeated access and handling requirements.
The third stage
Is automated warehousing technology stage automation technology has played an important role in promoting the development of storage technology and. At the end of the 50's and 60's, automated guided vehicle used have been developed and (AVG), automatic shelf, automatic access to robots, automatic identification and automatic sorting system. The 70's and 80's, rotary type shelves, mobile shelves, tunnel type stacking machine and other transportation equipment have joined the ranks of the automatic control, but this is only a partial automation of the various devices and independent application, known as the "islands of automation". With the development of computer technology, the work focus to the control and management, material requirements of real-time, coordination and integration, computer, data acquisition point between, between mechanical equipment controller and between them and the main communication between the computer can be timely summary information, warehouse computer timely records the ordering and arrival time, display inventory, planning staff can easily make supply decisions, they know what is produced, for what time what goods, send what goods, management personnel keep abreast of supply and demand. The application of information technology has become an important pillar of storage technology.
The fourth stage
Is the integration of automated warehousing technology stage in the late 70's and 80's, automation technology has been increasingly used in the field of production and distribution, obviously, "islands of automation" need to be integrated, so they formed the concept of "integrated system". In the integrated system, the organic coordination of the entire system, combined the overall efficiency and resilience of production greatly exceed the benefits of each part independently. Integrated storage technology as computer integrated manufacturing system (CIMS-Computer Integrated Manufacturing System) material is stored in the center of attention. Although people in 80 years has taken note of system integration, but so far in the integrated storage system has been built in our country is not much. Consists of people, equipment and control system in the integrated system, the three stage is the foundation.
The fifth stage
Intelligent automation storage technology.
