After the objective work is completed, the jig (10) and its
The elevating body (68) that moves 9 is sequentially lowered by a cam mechanism in the section from do), which turns on as the secondary rotor (6) rotates, to point ao. As a result, the jig (10)
As shown in the figure, the workpiece receiver is completely separated from the workpiece (W) held by the disk (63) and the vertically rotating disks (64) and (65). This separation process (point (do) to point (a')
)) is inspected to see if the intended work has been carried out properly, and if any defective work is found, the defective work is removed from the system. At the next point (ao), the jig (10) is raised again by the cam mechanism and sequentially returns to the height of the light, and stores only the corresponding good workpiece (W). The third conveying means (8), as shown in FIG.
) and a turntable (83) placed at its terminal end.
