Abstract

An arrangement for skinning poultry parts containing the poultry breast includes a conveying device having saddle elements configured for conveying the poultry parts in a conveying direction along a skinning device. The skinning device has at least one rotationally driven profiled roller and a guide element. The roller, together with an entry edge of the guide element, is adapted to form an entry gap for gripping the skin on the side of the poultry breast. The guide element has flank guide elements each adapted for laterally guiding the poultry part, wherein the flank guide elements have inner guide surfaces adapted for contacting the flesh of the poultry part. A method is also provided.

First claim

The invention claimed is:

1. An arrangement for skinning poultry parts containing a poultry breast, comprising:
a skinning device having at least one rotationally driven profiled roller and a guide element with an entry edge, the roller, together with an entry edge of the guide element, being adapted to form an entry gap for gripping skin on a side of the poultry breast, the guide element having flank guide elements each adapted for laterally guiding the poultry part, the flank guide elements having inner guide surfaces adapted for contacting flesh of the poultry part; and
a conveying device having saddle elements configured for conveying the poultry parts in a conveying direction along the skinning device.

2. The arrangement according to claim 1 , wherein the flank guide elements each comprise outer guide surfaces which are adapted for guiding the skin on the side of the poultry breast, each of the outer guide surfaces extending between the entry edge and a separating edge, each inner guide surface adjoining the respective outer guide surface at the separating edge.

3. The arrangement according to claim 2 , wherein the inner guide surfaces with their respective separating edge are each curved concavely.

4. The arrangement according to claim 1 , wherein the guide element comprises a contact surface arranged between the inner guide surfaces, the contact surface, starting from the entry edge, forms a run-on ramp which is inclined by an angle α relative to a tangential of the roller.

5. The arrangement according to claim 4 , wherein the separating edge in each case seamlessly laterally adjoins an edge the contact surface.

6. The arrangement according to claim 5 , wherein the contact surface edge is adapted to directly adjoin the entry edge.

7. The arrangement according to claim 1 , wherein the flank guide elements are configured such that a clear width between the inner guide surfaces tapers in the conveying direction.

8. The arrangement according to claim 1 , wherein the inner guide surfaces of the flank guide elements each have an end edge, each end edge being shorter than a respective portion of the separating edge of the same inner guide surface.

9. The arrangement according to claim 8 , wherein each of the inner guide surfaces is configured as an enveloping surface which spans a region between the end edge and the separating edge of the respective inner guide surface.

10. The arrangement according to claim 8 , wherein the separating edge, the contact surface edges and/or the end edges are in rounded form.

11. The arrangement according to claim 1 , wherein the roller is driven by a drive unit in such a manner that a circumferential speed of the roller is greater than a conveying speed of the conveying device.

12. The arrangement according to claim 1 , wherein, in a region of the flank guide elements, the roller has a peripheral surface profile which is inclined relative to its axis of rotation.

13. The arrangement according to claim 12 , wherein the peripheral surface profile in the region of the flank guide elements is inclined to end faces of the roller contrary to a direction of rotation of the roller.

14. The arrangement according to claim 4 , wherein, in a region of the contact surface forming the run-on ramp, the roller has a peripheral surface profile oriented parallel to its axis of rotation.

15. The arrangement according to claim 1 , wherein the skinning device is mounted such that the skinning device is resiliently deflectable relative to the conveying device.

16. The arrangement according to claim 1 , wherein the flank guide elements each comprise cutting means adapted for separating a connection between the skin and the poultry breast.

17. The arrangement according to claim 16 , wherein each cutting means is arranged on an exit side, downstream of the guide element relative to the conveying direction.

18. The arrangement according to claim 16 , wherein each of the cutting means has a cutting edge, the cutting edges being configured to be inclined relative to the conveying direction.

19. The arrangement according to claim 18 , wherein each cutting edge is sickle-shaped.

20. The arrangement according to claim 18 , wherein the cutting edges are each bevelled on both sides.

21. The arrangement according to claim 16 , wherein the cutting means are mounted such that the cutting means are resiliently deflectable transversely to the conveying direction.

22. A method for skinning poultry parts containing a poultry breast, comprising the steps of:
conveying the poultry parts in a conveying direction along a skinning device by saddle elements of a conveying device;
driving at least one profiled roller in rotation, wherein the roller, together with an entry edge of a guide element, forms an entry gap for gripping skin on a side the poultry breast;
automatically gripping the skin by the entry gap;
wherein lateral guiding of the poultry part is by flank guide elements, by contact of an inner guide surface of each flank guide elements with the flesh of the poultry part.

23. The method according to claim 22 , further comprising:
guiding the skin on the side of the poultry part by outer guide surfaces of the flank guide elements, each outer guide surface extending between the entry edge and a separating edge, each inner guide surface adjoining the respective outer guide surface at the separating edge.

24. The method according to claim 22 , further comprising:
elastic squeezing at least of part-regions of the poultry part by conveying the poultry part over a run-on ramp which is formed by a contact surface arranged between the inner guide surfaces, the contact surface of the run-on ramp, starting from the entry edge, is inclined by an angle α relative to a tangential of the roller.

25. The method according to claim 22 , further comprising:
lateral squeezing of the poultry part transversely to the conveying direction by the flank guide elements, a clear width of which between the inner guide surfaces tapers in the conveying direction.

26. The method according to claim 22 , wherein:
the driving of the roller is by a drive unit such that that a circumferential speed of the roller is greater than a conveying speed of the conveying device.

27. The method according to claim 22 , further comprising:
removal of the skin at least with a sub-component in a direction of end faces of the roller by a peripheral surface profile of the roller in a region of the flank guide elements which is oriented inclined relative to an axis of rotation of the roller.

28. The method according to claim 24 , further comprising:
pulling of the skin into the entry gap in the region of the run-on ramp in a direction of rotation of the roller by a peripheral surface profile oriented parallel to an axis of rotation of the roller.

29. The method according to claim 22 , further comprising:
resiliently deflecting the skinning device relative to the conveying device as one of the poultry bodies passes through.

30. The method according to claim 22 , further comprising:
separation of a remaining connection between the skin and the poultry part by cutting means.

31. The method according to claim 30 , wherein the separation takes place on an exit side, immediately before the poultry part has passed completely through the guide e
