Problems solved by technology

However, if the transportation volume is large and the transportation path is complicated, one crane cannot meet the transportation volume of the stacker, and multiple stackers need to be used at the same time
[0006] If one crane fails and stops its delivery operations, the entire line cannot work until that crane is fully restored

Embodiment Construction

[0026] The invention provides a new and improved automatic storage system, which includes a storage area with constant space, a loading device for loading workpieces in the storage area, and a controller. This automatic storage system is of the stacker type with a storage area and a loading device.

[0027] In the place of the stacker 100 shown in FIG. 3, the system is integrated with the processing equipment of the production line, or separate from the processing equipment in order to load workpieces subjected to constant processing steps. Automated guided vehicles (AGVs) 150 are used to transport workpieces 120 in the bay. AGV150 transports workpieces in and between warehouse partitions. Compared with the rail-guided vehicle (RGV) that moves along the track, the AGV does not need a track and can move directly to the floor of the production line. As shown in FIG. 3 , the AGV receiving the workpiece 120 from the stacker 100 performs an operation of transporting the workpiece...

Abstract

An automatic storage system using multi-cranes includes a pair of storage zones that are arranged in parallel each other to store workpieces, two stacker cranes that convey the workpieces, a crane path that is arranged between the storage zones so as to make the two stacker cranes movable, and two crane parking station that are respectively arranged at both ends of the crane path to stand by the cranes. Since two cranes can be used at the same time, only one automatic storage system can deal well with a great convey amount. Therefore, production equipment cost can be cut down. And, even though one crane is defective, the other can be used. Therefore, the defective crane has no influence upon an entire system.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 01101368.0 and the application date of January 4, 2001, and the invention title is "Automatic storage system for multiple cranes and its control method". technical field [0002] The present invention relates generally to automated storage systems for storing and retrieving workpieces. More specifically, the present invention relates to an automatic storage system with at least two multiple cranes and a control method thereof. Background technique [0003] According to different purposes, people have developed storage systems for storing workpieces with various structures and functions. Specifically, the storage systems used on the production line are combined with various processing equipment on the production line. Therefore, storage systems must supply accurate quantities of workpieces to processing equipment within the required time, and securely st...
