Abstract

A can curing oven including a housing assembly, a transfer assembly, and a number of heating units. The housing assembly defines a generally enclosed space. The transfer assembly is structured to support and move a number of can bodies. The transfer assembly includes an elongated transfer belt. The transfer belt is movably coupled to the housing assembly and is structured to move through the housing assembly enclosed space. The number of heating units are structured to generate an effective amount of received heat.

First claim

What is claimed is:

1. A can curing oven comprising:
a housing assembly including a heating assembly comprising a number of laterally disposed heating units; and
a transfer assembly including a transfer belt structured to support a number of can bodies in a vertical orientation and to move said number of can bodies past said number of laterally disposed heating units to cure a coating on said can bodies,
wherein said number of laterally disposed heating units comprises a plurality of modular and linkable heating unit plates,
wherein said modular and linkable heating unit plates are disposed in a single first row of opposed pairs.

2. The can curing oven of claim 1 wherein said number of laterally disposed heating units is structured to generate a total effective amount of received heat.

3. The can curing oven of claim 1 wherein said number of heating units includes a number of infrared heating units.

4. The can curing oven of claim 3 wherein said number of infrared heating units includes a plurality of infrared heating units.

5. The can curing oven of claim 3 wherein each infrared heating unit is selected from the group consisting of electrical infrared heating units, gas infrared heating units, or oil infrared heating units.

6. The can curing oven of claim 1
wherein said housing assembly includes an adjustable mounting assembly; and wherein said adjustable mounting assembly is structured to position each heating unit so as to be at an effective distance from a sidewall surface of a can body.

7. The can curing oven of claim 1 wherein said housing assembly is elongated and generally straight.

8. The can curing oven of claim 7
wherein said elongated generally straight housing assembly has a length, a width, and a height; wherein the length is between about 1.0 m and 6.0 m; wherein the width is between about 80 mm and 300 mm; and wherein the height is between about 200 mm and 500 mm.

9. The can curing oven of claim 7 wherein said transfer belt includes a plurality of segments; and wherein said transfer belt is structured to move over a looped path which extends through said elongated generally straight housing assembly.

10. The can curing oven of claim 3 wherein said transfer assembly includes a plurality of support pads; and wherein each said support pad structured to support a base portion of can body.

11. The can curing oven of claim 10 wherein each said support pad is one of a driven pad, a free pad or a fixed pad.

12. The can curing oven of claim 10 wherein each support pad includes a can coupling; and wherein each can coupling is selected from the group consisting of a magnetic coupling or a vacuum coupling.

13. The can curing oven of claim 1 wherein said number of heating units are structured to process can bodies at a maximum can decorator speed.

14. The can curing oven of claim 1 wherein said number of heating units are structured to become fully active in less than one second.

15. A can curing oven comprising:
a housing assembly including a heating assembly comprising a number of laterally disposed heating units; and
a transfer assembly including a transfer belt structured to support a number of can bodies in a vertical orientation and to move said number of can bodies past said number of laterally disposed heating units to cure a coating on said can bodies,
wherein said number of laterally disposed heating units comprises a plurality of modular and linkable heating unit plates,
wherein said modular and linkable heating unit plates are disposed in a plurality of stacked rows of opposed pairs of modular and linkable heating unit plates.

16. The can curing oven of claim 15 wherein said housing assembly is elongated and generally straight.

17. The can curing oven of claim 16 wherein said transfer belt includes a plurality of segments; and wherein said transfer belt is structured to move over a looped path which extends through said elongated generally straight housing assembly.

18. The can curing oven of claim 15 wherein said transfer assembly includes a plurality of support pads; and wherein each said support pad structured to support a base portion of can body.

19. The can curing oven of claim 18 , wherein each said support pad is one of a driven pad, a free pad or a fixed pad.

20. A can curing oven comprising:
a housing assembly including a heating assembly comprising a number of laterally disposed heating units; and
a transfer assembly including a transfer belt structured to support a number of can bodies in a vertical orientation and to move said number of can bodies past said number of laterally disposed heating units to cure a coating on said can bodies,
wherein said transfer assembly includes a plurality of support pads; and wherein each said support pad structured to support a base portion of can body,
wherein said plurality of support pads are driven support pads, wherein each driven pad is rotatably coupled to said transfer assembly transfer belt; and wherein said driven pad includes a body having a generally circular drive engagement surface,
wherein said housing assembly includes an elongated drive bar; and wherein said drive bar is disposed adjacent said transfer belt and structured to operatively engage said driven pad body drive engagement surface.
