Abstract

PURPOSE:To eliminate the danger to the worker when an industrial robot starts its working, by securing an automatic start of the robot only when it is within a range which is safe enough to the worker in case when each working shaft of the robot has an automatic start at its position. CONSTITUTION:A detector 6 works when each working shaft of a robot main body 1 is in the safety region which is sufficiently distant away from the worker. If either one of the working shafts gets out of the safety region, the detector 6 is turned off to the shifted shaft. Thus the output of an AND gate 8 is set at L level. Under these conditions, a gate 9 is not opened although a start switch 7 is pushed, and the terminal Q of an FF13 is kept at L level. Thus no start signal is supplied to a control part 3 of the robot 1, and as a result, the robot 1 cannot have an automatic start. At the same time, the outputs of inverters 11 and 12 are set at H level with the output of a gate 10 set at H level. Thus the shunt position fault signal is supplied to the control part 3 and a driving part 5, and the supply of the automatic operation command signal is discontinued to the robot. This discontinuation of supply is informed to the worker by means of a buzzer, and at the same time the motive power supply is cut off to the part 5 to forcibly stop the working of the robot.
