Multiple dynamo-electric machine parts handling and winding methods and apparatus
First Claim
1. Apparatus for winding coils of wire on the cores of dynamo-electric machine parts comprising:
- a conveyor for conveying unwound cores one after another to a transfer location;
a plurality of winders, each of which winds coils of wire on a core received by that winder; and
a transfer mechanism for picking up unwound cores one at a time from said conveyor at said transfer location and supplying said unwound cores to said winders, said transfer mechanism holding a sufficient number of unwound cores between picking up from said conveyor and supplying to said winder so that said winders can be operating simultaneously to wind coils while said transfer mechanism is transferring cores previously wound by said winders and picking up from said conveyor.

Abstract
A transfer mechanism is operatively disposed between a conveyor for dynamo-electric machine parts (such as electric motor armatures) and apparatus for simultaneously processing a plurality of those parts (e.g., by winding coils of wire on those parts). The transfer mechanism delivers processed parts to the conveyor and receives unprocessed dynamo-electric machine parts from the conveyor, one at a time in a single alignment position, at least partly concurrent with the processing of other parts. Loss in production time due to wire breakage at the processing apparatus is reduced by substantially instantaneously controlling the broken wire (e.g., by retracting that wire relative to the associated wire dispenser) while continuing to move the wire dispensers.

22. The method of operating apparatus for winding coils of wire on cores of dynamo-electric machine parts, said apparatus including a conveyor for conveying unwound cores one after another to a transfer location and a plurality of wire coil winders, said method comprising the steps of:
-
simultaneously operating said winders to wind coils of wire on respective unwound cores received by the winders; picking up unwound cores one after another from said conveyor at said transfer location, said picking up step being at least partly performed during performance of said operating step; holding unwound cores picked up in said picking up step until additional unwound cores are required by said winders for continued performance of said operating step; and transferring unwound cores held in said holding step to said winders and moving cores wound in said operating step to said conveyor, wherein said moving step is performed simultaneously with said operating step. - View Dependent Claims (23, 24, 25, 26, 27, 28)
