Abstract

A safety device connected to an industrial robot and mounting a tool characterized by an arrangement including a first and second flange for stopping the robot in response to a predetermined axially applied force to the tool and a second arrangement including the second flange and a third flange for stopping the robot in response to a shear force being applied to the tool so that a tool is protected both against shear forces and axially applied thrust during a collision in operation or during programming of the robot.
