装置。[Claims for Utility Model Registration] (1) A workpiece positioning and transporting device that transports a workpiece from a predetermined receiving position to a delivery position while rotating the workpiece around its center line, which a first rotating arm arranged to be rotatable; a second rotating arm attached to the first rotating arm so as to be relatively rotatable about a second axis parallel to the first axis; disposed between a position-fixed member provided near the first axis and the second rotating arm;
As the rotating arm is rotated about the first axis, the second rotating arm is rotated about the second axis in the opposite direction to the rotating direction of the first rotating arm. a first relative rotation mechanism that mechanically rotates relative to the first rotation arm by approximately the same angle as the rotation angle of the rotation arm; and a first relative rotation mechanism that rotates together with the second rotation arm about the second axis. a workpiece receiving member that supports the workpiece rotatably around the centerline in a posture in which the centerline is parallel to the second axis, and is provided with an upwardly facing workpiece receiver; a drive device that rotates the first rotating arm around the first axis so that the first rotating arm is moved from the receiving position to the delivery position; an engaging member that is attached so as to be relatively rotatable about a third axis parallel to the second axis located on an extension of the center line of the workpiece, and that is engaged with the workpiece in a relatively non-rotatable manner; The engaging member is disposed between a portion of the rotating arm located near the second axis and the engaging member, and as the second rotating arm is rotated about the second axis. and a second relative rotation mechanism that mechanically rotates the mating member relative to the second rotation arm about the third axis. (2) A workpiece positioning and transporting device that transports the workpiece from a predetermined receiving position to a delivery position while rotating the workpiece around its center line, the workpiece positioning and transporting device being arranged so as to be rotatable around a first axis at the base end. a first rotating arm; a second rotating arm attached to the first rotating arm so as to be relatively rotatable about a second axis parallel to the first axis; a second rotating arm provided near the first axis; disposed between a position-fixed member and the second rotating arm;
A first mechanism for mechanically rotating the second rotating arm relative to the first rotating arm about the second axis as the rotating arm is rotated about the first axis. a relative rotation mechanism; a third rotation arm parallel to the second axis on the second rotation arm;
a holding device that is attached so as to be relatively rotatable about an axis, and holds the workpiece in a position where the centerline is parallel to the third axis so as not to be rotatable about the centerline; The holding device is disposed between a portion located near a second axis and the holding device, and as the second rotating arm is rotated around the second axis, the holding device is rotated in the second rotation. a second relative rotation mechanism that mechanically rotates the movable arm relative to the third axis; and a second relative rotation mechanism that mechanically rotates the first rotation arm so that the holding device can be moved from the receiving position to the delivery position. A workpiece positioning and conveying device comprising: a drive device that rotates the workpiece around the first axis.
