Abstract
A chuck mechanism that grips a workpiece is configured to be able to twist and rotate the gripped workpiece around a longitudinal axis of the workpiece. A control unit is provided with a first control unit and a second control unit. The first control unit drives an articulated robot to which a bending mechanism for bending the workpiece is attached, and twists the workpiece clamped by the bending mechanism around the longitudinal axis of the workpiece within a preset twisting angle range. When the angle of twisting by the first control unit exceeds the twisting angle range, the second control unit controls the chuck mechanism to twist the workpiece around the longitudinal axis of the workpiece.
