Abstract
An overtravel detecting device, mounted on an angularly movable shaft of an industrial robot for mechanically determining and detecting the limits of rotation of the movable shaft, is attached to a rotating shaft (12) of a wrist portion (10) of an industrial robot and is provided with a pattern plate member (22) having two grooved paths (24) for setting the limits of rotation of the rotating shaft at predetermined position with respect to an origin position of the rotation, and a detecting element constituted by a limit switch (32) for transmitting an overtravel signal when the switch comes into contact with stop walls (24a, 24b) formed at ends of the two grooved paths for setting limits of rotation.
