Abstract
An industrial robot system comprising a single working machine, and a plurality of robots arranged so as to transfer a work to and from this working machine. The operation of these robots and the working machine is controlled by a single control unit, and the operation of all the robots is controlled in a realtime manner in synchronism with the operation of the working machine, thereby ensuring the smooth operation of the overall system while obviating waiting time of each robot and the working machine without using a conventional mutual interlock system. The control unit is set so that clocks of the robots and the working machine and the system clock are counted up in the same cycle time, simultaneously therewith the original point clock value of the robot or the working machine located on the most upstream side of the system is set as the original clock value of the system, and each of the robots and the working machine is operated as the count of the system clock reaches the original clock value of the robot on the working machine.
