Abstract

A production line (100,200,300,400) for manufacturing wound core components (10,10′) of a dynamo electric machine, comprising a central processing zone (101) provided with at least a winder (104,104′) for winding coils (15) to produce wound core components, a downstream processing zone (111) for finishing the wound core components. The production line further comprises a first load and unload device (105) for transferring the core components to be wound to at least a winder (104,104′) from a waiting position (103a), or from an upstream transport carrier (108a), located at a first position (G), for transferring core components to be wound from an upstream processing zone (201). The first load and unload device (105) transferring wound core components from the at least a winder (104,104′) to a downstream transport carrier (108b), located at a second position (A), for transferring wound core components to the downstream processing zone (111).

Claims

1. A production line for manufacturing wound core components of dynamo electric machine, the production line comprising:

a central processing zone comprising at least one winder for winding coils to produce the wound core components, the winder having a positioning casing therein for positioning and holding core components to be wound with respect to needles of the winder; and

a downstream processing zone for finishing the wound core components;

the production line further comprising;

a first load and unload device for transferring the core components to be wound directly to the positioning casing from an upstream transport carrier located at a first position;

wherein;

the upstream transport carrier transfers the core components to be wound from an upstream processing zone;

the first load and unload device transfers the wound core components directly from the positioning casing to a downstream transport carrier located at a second position different from the first position; and

the downstream transport carrier transfers the wound core components to the downstream processing zone.

2. The production line of claim 1 wherein the upstream transport carrier moves with alternative backwards and forwards motion on a same travel stretch between the upstream processing zone and the central processing zone.

3. The production line of claim 2 wherein the downstream transport carrier moves with alternative backwards and forwards motion on a same travel stretch between the central processing zone and the downstream processing zone.

4. The production line of claim 1 wherein the downstream transport carrier moves with alternative backwards and forwards motion on a same travel stretch between the central processing zone and the downstream processing zone.

5. The production line of claim 1 wherein the upstream transport carrier moves on a recirculation travel conveyor between the upstream processing zone and the central processing zone.

6. The production line of claim 5 wherein the downstream transport carrier moves on a recirculation travel conveyor between the central processing zone and the downstream processing zone.

7. The production line of claim 1 wherein the downstream transport carrier moves on a recirculation travel conveyor between the central processing zone and the downstream processing zone.

8. The production line of claim 1 wherein the central processing zone comprises at least two winders;

and

the first load and unload device transfers unwound core components to the at least two winders.

9. The production line of claim 1 wherein the upstream processing zone comprises:

a plurality of machines;

wherein each machine of the plurality of machines performs a respective production operation on the core components;

first transfer means for positioning the core components according to a sequence order at the machine; and

a second load and unload device for transferring the core components from the first transfer means to the upstream transport carrier.

10. The production line of claim 9 wherein the first transfer means comprises at least two seats for transferring the core components to the machines, wherein each of the seats transfers a specific variation of a core component to the machines;

and the upstream transport carrier comprises at least two seats for transferring the core components to the central processing zone, wherein each of the seats of the upstream transport carrier transfers a specific variation of a core component.

11. The production line of claim 1 wherein the downstream processing zone comprises:

a plurality of machines;
