PURPOSE:To convey parts having different sizes with one pickup arm, by providing a two-stage structure of a part conveying arm, and arranging the side corresponding to a part having a large width, on the lower side. CONSTITUTION:First hooking parts 231a, which hold a part having a large width, are arranged at the lower side. Second hooking parts 231b, which hold a part having a small width, are arranged at the upper side. The operating range of the opening and closing of pawl pieces 230 are set in correspondnece with the part having the large width. Then the operating range of the opening and closing for the part having the smaller width can be set within the part having the large range. Therefore, the operating range of the opening and closing can be commonly used. The parts having the large width and the small width can be held by the operating mechansim having the same opening and closing range. Thus, the parts having the different sizes can be picked up with the common opening and closing mechanism. Independent opening and closing control mechansims are not required for the different parts. |
