Abstract: The device for turning and aligning an object useful for a system for the automatic feeding of joining element into processing equipment such as stud welding heads within sheet metal forming tools, comprises a drive implemented over a wedge drive (2), a wedge element (3), which is movably arranged parallel to the rotational axis, where the wedge element is reset by spring force, and a clamping element (6), which is movably arranged. The wedge drive is reset independently by spring force, where the clamping element is force-guided relative to the wedge element over a positive guide. The device for turning and aligning an object useful for a system for the automatic feeding of joining element into processing equipment such as stud welding heads within sheet metal forming tools, comprises a drive implemented over a wedge drive (2), a wedge element (3), which is movably arranged parallel to the rotational axis, where the wedge element is reset by spring force, and a clamping element (6), which is movably arranged. The wedge drive is reset independently by spring force, where the clamping element is force-guided relative to the wedge element over a positive guide, which allows linear motion with superimposed rotation. The guiding is limited between the clamping element and the wedge element by a mechanical stop into a direction. The position of the wedge element is provided so that the position of the clamping element is determined into the position and the restoring movement is released by which applied restoring force of the spring is blocked or fixed in an interval between the wedges and the wedge element. The wedge drive comprises an active surface, which is parallely directed to the direction of motion of the drive wedge and in spite of relative movement between the drive wedge and the output wedge in contact with the wedge and the output wedge in which area releases no movement of the clamping relative to the output wedge. Two clamping elements are oppositely arranged and are separately moved during the activity of the wedge drive in synchronous manner. The clamping elements are synchronously implemented in a coaxial rotation of the same direction of rotation. One of the clamping elements disposes in funnel-shaped manner at primary side for the objects to be inserted. One of the clamping elements is provided at an inner side so that it is adapted on the geometry of the object to be inserted and not additionally pushed into the plug-in direction by the stop over a fixed end position. The inserted object is clamped into the device by a preload force of the spring, and the inserted object is hindered to the clamping element at a movement against the insertion direction through form end. The translation of the wedge drive is adapted so that the directional bias is formed between the output wedge and the clamping element and releases the clamping element by the wedge drive in a fixed movement area of the wedge drive against a housing (1) executed exclusively the rotation and revolves the clamped object around a fixed angle. An independent claim is included for a method for turning and aligning of an object.
