Abstract

The disclosure relates to a sealing tool for a packaging machine which comprises a tool lower part with at least one centrifugal separator for separating a particle-laden gas flow. The disclosure further relates to a method for separating a particle-laden gas flow at a sealing tool of a packaging machine, where the particle-laden gas flow is separated by way of a centrifugal separator provided at a tool lower part of the sealing tool.

First claim

What is claimed is:

1. A packaging machine, formed as a tray sealer or a deep-drawing packaging machine, comprising a sealing tool for the packaging machine, wherein the sealing tool comprises a tool lower part with at least one centrifugal separator for separating a particle-laden gas flow.

2. The packaging machine according to claim 1 , wherein the centrifugal separator is configured as a tangential cyclone separator.

3. The packaging machine according to claim 1 , wherein the centrifugal separator comprises an inlet cylinder and an inlet which tapers towards the inlet cylinder.

4. The packaging machine according to claim 3 , wherein the inlet is associated with a tray receptacle of the tool lower part.

5. The packaging machine according to claim 1 , wherein the tool lower part comprises at least one extraction duct.

6. The packaging machine according to claim 1 , wherein the tool lower part comprises at least one gas flushing duct.

7. The packaging machine according to claim 1 , wherein the tool lower part comprises a particle collection container for the centrifugal separator.

8. The packaging machine according to claim 1 , wherein the tool lower part comprises several centrifugal separators.

9. The packaging machine according to claim 1 , wherein the centrifugal separator at the tool lower part is configured to separate a particle-laden gas flow blown through the former and/or to separate a particle-laden gas flow sucked through the former.

10. The packaging machine according to claim 1 , wherein the centrifugal separator can be connected to a pump that can be employed at the tool lower part for atmosphere exchange.

11. The packaging machine according to claim 1 , wherein the tool lower part is assembled from several plates disposed one above the other in a stack-like manner, and wherein the centrifugal separator is formed to be integrated within at least two plates that are disposed one above the other.

12. The packaging machine according to claim 1 , wherein the centrifugal separator comprises a cylindrical insert built into the tool lower part and having a conical separation section for the particle-laden gas flow.

13. A method for separating a particle-laden gas flow at a sealing tool of a packaging machine, wherein the particle-laden gas flow is separated by way of a centrifugal separator provided at a tool lower part of the sealing tool.

14. The method according to claim 13 , wherein the centrifugal separator is operated with a pump that can be employed at the tool lower part for atmosphere exchange.

15. A sealing tool for a packaging machine, wherein the sealing tool comprises a tool lower part with at least one centrifugal separator for separating a particle-laden gas flow, wherein the tool lower part is assembled from several plates disposed one above the other in a stack-like manner, and wherein the centrifugal separator is formed to be integrated within at least two plates that are disposed one above the other.

16. The sealing tool according to claim 15 , wherein the centrifugal separator is configured as a tangential cyclone separator.

17. The sealing tool according to claim 15 , wherein the centrifugal separator comprises an inlet cylinder and an inlet which tapers towards the inlet cylinder.

18. The sealing tool according to claim 17 , wherein the inlet is associated with a tray receptacle of the tool lower part.

19. The sealing tool according to claim 15 , wherein the tool lower part comprises at least one extraction duct.

20. The sealing tool according to claim 15 , wherein the tool lower part comprises at least one gas flushing duct.
