Abstract

Angular regions (A, B) for turning a trunk body (12) of an industrial robot can be changed in accordance with an operation of the industrial robot by setting movable stoppers (18, 20). Turning movement can be stopped by an electrical means (LS1, LS2, LS3, LS4, LS5) to protect a drive motor and a drive mechanism, just before a stopper (22) fixed on the trunk body collides with mechanical stoppers (14, 16, 18, 20). An accident based on an error operation of the movable stoppers can be prevented by disposing proximity detectors (PS1, PS2, PS3, PS4).
