ABSTRACT:
Automatic machinery for performing multiple operations on different parts of workpieces includes an incrementally rotating, workpiece supporting turret provided with three workpiece supports. Upon rotating of the turret, a workpiece loaded on a support located at a first position is indexed about the axis of the turret to a second position at which a first operation is performed thereon, then to a third, idle position. Continued rotation of the turret results in an index of the workpiece to the first position, then again to the second position at which a second operation is performed thereon. After the next index to the third position, the workpiece is unloaded from the support. As the turret is indexed, the workpiece is rotated relative to the turret whereupon the workpiece is oriented differently each time it reaches the second position causing the operations to take place on different parts of the workpiece. The workpiece is loaded on one of the three supports following every second index and a workpiece is unloaded from one of the supports following alternate indexes. An operation is performed on a workpiece following each index. In the specifically disclosed embodiment, the workpiece is a two pole stator frame which is to be provided with two identical pieces of insulation at diametrically opposed points on the stator frame. The insulation is delivered along a predetermined path by a delivery mechanism. Accordingly, each stator frame is rotated through a net angle of 180.degree. relative to the turret between the two intervals in which it is located at the second position in order to place the appropriate parts of the stator frame in the predetermined insulation delivery path.
The disclosed mechanism includes means for rotating the turret and a planetary gear system for rotating the stator frame relative to the turret in order to present the proper portion of each stator frame at the operation station at each interval.
