Claims

[Scope of utility model registration request]

Rotation from a standing position to a reclining posture in the front and back direction in which the tip is located directly above the workpiece transfer position of the workpiece transfer device, and rotation from the standing posture to a horizontally lying posture in which the tip is located at the workpiece setting position of the machine tool. A rotary table is provided at the tip of the rotatable robot arm, which is driven by one actuator to rotate in forward and reverse directions within a range of 270 degrees around the longitudinal axis of the arm. A loading chuck and an unloading chuck for holding a shaft-like work in a direction perpendicular to the length direction of the arm are installed in parallel, and the rotary table is rotated within the 270 degree rotation range. A workpiece transfer robot equipped with a rotation angle regulating means equipped with a position switching stopper that stops at a 90 degree position and a 180 degree position.
