Abstract

The invention relates to an interface between a knife and a knife holder, wherein the knife and the knife holder are designed such that the knife can be mounted on the knife holder in such a way that the knife is initially positioned on the knife holder in the axial direction, and then by rotating either the knife relative to the knife holder and/or the knife holder relative to the knife, the knife is locked on the knife holder with respect to the axial direction, wherein the knife has a single central fastening opening which is delimited by a knife edge region, and the knife holder has a fastening section for the fastening opening of the knife, which is delimited by a holder edge region.

First claim

What is claimed is:

1. A blade mount for a high-speed slicer, the blade mount being configured such that a blade can be attached thereto by first moving the blade in an axial direction parallel to a rotational axis of the blade mount to place the blade on the blade mount, and then securing the blade in the axial direction at the blade mount by rotating the blade about the rotational axis relative to the blade mount and/or by rotating the blade mount about the rotational axis relative to the blade, the blade mount comprising:
a first part including a ring and a plurality of mount projections spaced apart around a periphery of the ring and projecting radially outwardly from the periphery of the ring, the ring and the plurality of mount projections being formed as a single component, wherein the plurality of mount projections are configured to secure the blade in the axial direction at the blade mount when the blade is placed on the blade mount and at least one of:
the blade is rotated about the rotational axis relative to the blade mount; and
the blade mount is rotated about the rotational axis relative to the blade;

a second part; and
a clamping device, wherein:
the clamping device can be adjusted between a release state and a clamping state; and
the clamping device clamps the blade between the first part and the second part such that the first and second parts contact opposite faces of the blade when the clamping device is in the clamping state and the blade is disposed between the first and second parts.

2. A blade mount in accordance with claim 1 , wherein the blade mount has a fastening section for a fastening opening of the blade which is bounded by a marginal mount region.

3. A blade mount in accordance with claim 1 , wherein the blade mount has a mount-side component of a security against rotation for the blade.

4. A blade mount in accordance with claim 3 , wherein the mount-side component comprises at least one securing pin or two securing pins spaced apart in a peripheral direction.

5. A blade mount in accordance with claim 4 , wherein at least one securing pin is able to be lowered by means of the blade against a restoring force on the attachment of the blade.

6. A blade mount in accordance with claim 3 , wherein the security against rotation is arranged or formed at a contact area for the blade disposed radially outside a marginal mount region.

7. A blade mount in accordance with claim 1 , wherein the blade mount has a contact section having a contact area for the blade which is spaced apart in the axial direction with respect to a marginal mount region.

8. A blade mount in accordance with claim 7 , wherein an axial spacing is present between a contact plane defined by the contact area and a locking plane which is defined by a rear side of the marginal mount region facing in a direction of the contact plane.

9. A system having a blade mount in accordance with claim 1 and having a blade which is configured for attachment to the blade mount by first moving the blade in the axial direction to place the blade on the blade mount and then securing the blade in the axial direction at the blade mount by rotating the blade about the rotational axis relative to the blade mount and/or by rotating the blade mount about the rotational axis relative to the blade.

10. A system in accordance with claim 9 , wherein the blade has a single central fastening opening which is bounded by a marginal blade region.

11. A system in accordance with claim 9 , wherein a marginal mount region has a larger axial thickness than a marginal blade region, and/or wherein a marginal blade region and a marginal mount region are coordinated with one another such that on setting on the blade, a rotation of the blade is suppressed until the marginal blade region has passed the marginal mount region.

12. A system in accordance with claim 9 , wherein:
the first part includes a mounting edge;
the second part has a contact surface that defines a contact plane;
a rear side of the mounting edge faces in a direction of the contact plane and defines a locking plane;
the contact plane and the locking plane are parallel to and spaced apart from one another; and
an axial spacing between the contact plane and the locking plane of the blade mount is larger in at least the release state of the blade mount than an axial thickness of a marginal blade region bounding a fastening opening.

13. A system in accordance with claim 12 , wherein the axial spacing is smaller than 1 mm, or smaller than 0.5 mm, or smaller than 0.3 mm, or smaller than 0.1 mm.

14. A system in accordance with claim 9 , wherein the clamping device clamps the blade at a marginal blade region which bounds a central fastening opening of the blade.

15. A system in accordance with claim 14 , wherein the central fastening opening of the blade is bounded at a plurality of radially inwardly directed blade projections of the marginal blade region.

16. A blade head of a high-performance slicer, the blade head having a system in accordance with claim 9 .

17. A high-performance slicer having a system in accordance claim 9 .

18. A blade mount in accordance with claim 1 , wherein the first part is formed by a fastening section for a fastening opening of the blade.

19. A blade mount in accordance with claim 18 , wherein the first part is formed by a marginal mount region bounding the fastening section.

20. A blade mount in accordance with claim 1 , wherein the second part is formed by a contact section for the blade.

21. A blade mount in accordance with claim 1 , wherein the clamping device comprises a spring arrangement which acts between the first part and the second part.

22. A blade mount in accordance with claim 1 , wherein the clamping device is preloaded into the clamping state.

23. A blade mount in accordance with claim 1 , wherein the clamping device comprises at least one plate spring and/or at least one plate spring package.

24. A blade mount in accordance with claim 1 , wherein the clamping device is adjustable by setting on the blade.

25. A blade mount in accordance with claim 1 , further comprising an actuation device configured to adjust the clamping device between the release state and the clamping state.

26. A blade mount in accordance with claim 25 , wherein the actuation device acts against a preload on the clamping device to adjust the clamping device from the clamping state into the release state when the actuation device is actuated.

27. A blade mount in accordance with claim 25 , wherein at least one of:
the actuation device is a pneumatic device, a hydraulic device or an electric device; and
the actuation device exerts excess pressure on a closed inner space of the blade mount on actuation.

28. A blade mount in accordance with claim 1 , wherein at least one counter-weight is provided for setting the mass distribution of the arrangement comprising the blade and the blade mount and rotating in operation, with the counter-weight being at least partly integrated into the blade mount.

29. A blade mount in accordance with claim 28 , wherein at least a part of the counter-weight is formed by a functional part which bounds an inner space of the blade mount which can be pressurized, and/or wherein the counter-weight is arranged at both sides of a blade plane.

30. A blade mount in acc
