ABSTRACT:
An automatic conveyance system comprises a buffer storage for storing a plurality of unit racks containing units; a plurality of test cells for testing the units contained in the unit racks; and a plurality of test cell controllers, each being provided in one of the test cells and each accepting an operator's requirement to take out a unit rack from the buffer storage, to store a unit rack into the buffer storage, or to convey a unit rack from one of the test cells to another one of the test cells. The system is provided with a plurality of automatic guided vehicles for conveying unit racks. A computer is connected to the test cell controllers by a single bus and has information on the unit racks stored in the buffer storage. The computer controls each vehicle based on the requirement accepted by one of the test cell controllers and the information on the unit racks stored in the buffer storage so that the automatic guided vehicle conveys the unit rack from the buffer storage to a desired one of the test cells, between two of the test cells, or from one of the test cells to the buffer storage, whereby by supplying a requirement by an operator without knowing what, where, and when the units are stored in the buffer storage, a desired conveyance is made possible.
