Abstract

A resin application station has processing units for heating dynamo-electric machine components. In one or more of the processing units batches of components are placed in fixtures on vertically rotating support plates. The vertically rotating support plates are mounted in cabinets. Heated air is circulated in the cabinets to control the ambient temperature. The components travel through regions of the controlled temperature ambient as the support plates rotate and are heated to process temperatures. Intermittent rotation of a support plate in a unit allows loading and unloading of an individual component from the unit while the support plate is stationary. The support plate rotations in all the units are synchronized to increase the station throughput

Claims

1-26. -26. (canceled)

27. A method for applying resin to dynamo-electrical machine components, comprising:

loading said components in first holding fixtures, wherein said first holding fixtures are disposed in an annular region on the face of a first vertical support plate rotatably mounted in a preheating cabinet;

flowing heated air through said cabinet to provide a temperature controlled ambient therein;

rotating said first vertical support plate such that said loaded components travel through said controlled temperature controlled ambient and are heated to a predetermined temperature;

unloading said heated components from said preheating cabinet;

transferring said unloaded heated components to a resin application unit, wherein said resin application unit comprises means for applying a quantity of resin to said components; and

applying resin to said transferred components in said resin application unit.

28. The method of claim 27 wherein said rotating said first vertical support plate further comprises rotating said first vertical plate intermittently with first periods of rotation alternating with first periods of pause such that that a said first holding fixture disposed on said first vertical support plate is aligned with a first loading position,

wherein said unloading said heated components from said preheating cabinet further comprises unloading a said heated component from said first holding fixture aligned with said first loading position during a said first period of pause, and

wherein loading said components in first holding fixtures further comprises loading a said component in said first holding fixture aligned with said first loading position from which said heated component has been unloaded during same said first period of pause.

29. The method of claim 28 wherein transferring said unloaded heated components to a resin application unit further comprises:

reloading said unloaded heated components in an empty second holding fixture, wherein a plurality of said second holding fixtures are disposed in an annular region on the face of a second vertical support plate rotatably mounted in said resin application unit, and wherein said reloading occurs while said second vertical support plate is stationary and said empty second holding fixture is aligned with a second loading position; and

wherein applying resin to said transferred components in said resin application unit further comprises;

intermittently rotating said second vertical support plate with second periods of rotation alternating with second periods of pause to advance said reloaded heated component away from said second loading position through said resin application unit; and

using said means for applying a quantity of resin during a second period of pause after said advanced component has moved away from said second loading position to apply resin said advanced component.

30. The method of claim 27 further comprising:

heat curing the resin applied to said components.

31. The method of claim 30 wherein heat curing the resin applied to said components further comprises:

transferring said components with resin applied to them out of said resin application unit;

loading said components in third holding fixtures, wherein said third holding fixtures are disposed in an annular region on the face of a third vertical support plate rotatably mounted in a resin-curing cabinet;

flowing heated air through said resin-curing cabinet to provide a temperature controlled ambient therein; and

rotating said third vertical support plate such that said loaded components travel through said controlled ambient to heat said applied resin.
