Abstract

Devices for preserving components with a preservative agent, e.g., for cavity preservation of motor vehicle body components, are disclosed. An exemplary device, in addition to a preservative agent, may apply a hardener configured to react with the preservative agent, which causes the preservative agent to harden.

First claim

The invention claimed is:

1. An application device, comprising:
a preservative agent line arranged to feed a preservative agent and a hardener line arranged to feed a hardener;
a first nozzle in fluid communication with the preservative agent line and a second nozzle in fluid communication with the hardener line;
a reactive substance, which at least inhibits the hardening, the reactive substance provided to flow through, coat, and/or fill the application device including at least one of the first nozzle and the second nozzle; and
a monofunctional substance, which reacts with at least one of the preservative agent and the hardener, to at least inhibit the hardening, the monofunctional substance provided to flow through, coat, and/or fill the application device including at least one of the first nozzle and the second nozzle;
wherein the device is arranged to flow at least one of a solvent and a rinsing agent through at least one of the first nozzle and the second nozzle; and
wherein the device is arranged to apply the preservative agent and the hardener to a component.

2. The device according to claim 1 , further comprising at least one first application element with at least one first outlet opening.

3. The device according to claim 2 , wherein the first application element has at least one of the first nozzle and the second nozzle on which the first outlet opening is provided.

4. The device according to claim 3 , wherein the preservative agent line and the hardener line discharge into the first application element in such a way that the preservative agent and the hardener can be mixed in the first application element.

5. The device according to claim 3 , wherein the preservative agent line and the hardener line discharge into the first application element in such a way that the preservative agent and the hardener can be mixed upstream from the first nozzle or in the first nozzle.

6. The device according to claim 3 , wherein a second outlet opening is provided on the first nozzle.

7. The device according to claim 3 , wherein the first application element has the second nozzle on which is provided a second outlet opening.

8. The device according to claim 7 , wherein the preservative agent line leads to the first outlet opening and the hardener line leads to the second outlet opening in such a way that the preservative agent and the hardener mix in flight or on the component to be preserved.

9. The device according to claim 2 , further comprising a second application element with at least one second outlet opening.

10. The device according to claim 9 , wherein the second outlet opening is provided on the second nozzle.

11. The device according to claim 9 , wherein the preservative agent line leads to the first outlet opening and the hardener line leads to the second outlet opening in such a way that the preservative agent and the hardener can be mixed in flight or on the component to be preserved.

12. The device according to claim 9 , wherein the first application element is arranged on a preservative agent application station and the second application element is arranged on a hardener application station, wherein the preservative agent application station and the hardener application station are positioned along a conveying route for motor vehicle body components.

13. The device according to claim 9 , wherein:
at least one of the first application element and the second application element is arranged to be guided into a cavity to be preserved; and
at least one of the first application element and the second application element is an application tube or a probe.

14. The device according to claim 9 , wherein
the preservative agent line and the hardener line discharge into at least one of the first and the second application element in such a way that the mixing of the preservative agent and of the hardener is initiated in at least one of the following:
in flight;
on the component to be preserved;
in the first application element; and
in the first nozzle.

15. The device according to claim 1 , further comprising a mixer disposed in at least one of
a first application element; and
the first nozzle.

16. The device according to claim 1 , wherein
the device is arranged to mix the preservative agent and the hardener in at least one of the following:
in the device;
in the application device;
in a first application element;
in the first nozzle;
outside the application device;
outside at least one of the first and a second application element;
outside at least one of first and second outlet openings;
in flight; and
on the component to be preserved.

17. The device according to claim 1 , wherein the device is configured such that application of the preservative agent and of the hardener can be executed simultaneously or sequentially.

18. The device according to claim 1 , wherein
at least one of a first robot arm and a second robot arm is arranged along a conveying route for motor vehicle body components; and
at least one of a first application element and a second application element is arranged on at least one of the first and the second robot arm.

19. The device according to claim 1 , wherein the device is arranged to atomize at least one of the preservative agent and the hardener.

20. The device according to claim 1 , wherein the device is adapted for cavity preservation of motor vehicle body components.

21. The device according to claim 1 , wherein the preservative agent is a wax.
