Abstract

An improved conveying system in a parallel processing production line for dynamo-electric machine components having a magnetic core, the conveying system having a main conveyor extending along all of the processing machines of the production line and a load/unload device for transferring components between the main conveyor and a selected processing machine. Components to be processed are loaded directly from the main conveyor onto the load/unload device without the use of an intermediate conveyor. The load/unload device has a base platform with an alignment area at which transfer between the load/unload device and either the main conveyor or a selected processing machine occurs. Two component holders (e.g., collets) are movably mounted on the base platform for alternate positioning at the alignment area. The load/unload device alternately positions the gripping ends of the component holders adjacent the main conveyor and a selected processing machine. The central axis of the load/unload device remains fixed during movement of the load/unload device.

Claims

1. Apparatus for conveying dynamo-electric machine components having a magnetic core from a winding machine which winds coils of wire having coil leads on said core to a fusing machine which forms permanent mechanical and electrical connections between said coil leads and said components comprising:

first and second component holders;

first means for successively positioning said component holders for exchanging components with said winding machine and for exchanging components with said fusing machine; and

second means, operable when said first means positions said component holders for exchanging components with said winding machine, for successively positioning each of said component holders relative to said winding machine so that said first component holder can receive a first one of the components from said winding machine and so that said second component holder can thereafter release a second one of the components to said winding machine, said second means being further operable, when said first means positions said component holders for exchanging components with said fusing machine, for successively positioning each of said component holders relative to said fusing machine so that said second component holder can receive a third one of the components from said fusing machine and so that said first component holder can thereafter release the first one of the components to said fusing machine.

2. The apparatus defined in claim 1 wherein said first, second, and third components are dynamo-electric machine armatures.

3. The apparatus defined in claim 2 wherein said dynamo-electric machine armatures are electric motor armatures.

4. The apparatus defined in claim 1 wherein said winding machine and said fusing machine are disposed adjacent to one another in a predetermined plane, and wherein said first means comprises means for rotating said first and second component holders, as a unit, about an axis which is substantially perpendicular to said plane.

5. The apparatus defined in claim 4 wherein said second means comprises means for shifting said first and second component holders relative to said axis.

6. The apparatus defined in claim 5 wherein said means for shifting shifts said first and second component holders in a plane which is transverse to said axis.

7. The apparatus defined in claim 1 further comprising:

third and fourth means for respectively reciprocating said first and second component holders alternately toward and away from the winding machine or fusing machine with which said first means has positioned said component holders for exchanging components.
