PURPOSE:To take exact measures against parts abnormal holding by providing a detection member which can check whether or not a parts is temporarily locked to a holding device in a device to supply a parts to a desired position with the parts engaged with the head of a supply rod. CONSTITUTION:With a detecting member 23 firstly located at a retraction position, and a clogging member 15 closed, when a bolt 3 is supplied in the recessed section 12 of a holding device 10 through a parts supply passage 20, a detection member 23 advances to detect whether the bolt is properly held or not. If it is judged that the bolt is held properly, the holding device 10 is moved by a cylinder 19 to the side of a box wrench 4, and when the bolt 3 is stopped at the position where the bolt 3 is aligned with the wrench 4, the wrench 4 advances by a specified stroke while rotating, and the bolt head 2 is fitted in an engaging hole 5 and absorbed and held by a magnet 6. When the clogging member 15 is retracted by a cylinder 17 to open the recessed section 12, the holding device 10 has already returned to a parts receiving position. |
