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.
Claims18
A system comprising:
- a blade for a high-speed slicer, the blade being configured for rotation about a rotational axis and configured for attachment to a blade mount of the slicer by first moving the blade in an axial direction parallel to the rotational axis to place the blade on the blade mount and then securing the blade in the axial direction by rotating the blade about the rotational axis and relative to the blade mount and/or by rotating the blade mount about the rotational axis and relative to the blade, wherein:
- the blade has a single fastening opening defined by an opening edge for attachment to the blade mount;
- the opening edge has a non-circular shape;
- the opening edge defines a plurality of blade projections arranged in intervals along the fastening opening and extending radially inward toward the rotational axis;
- the plurality of blade projections have a uniform thickness in the axial direction;
- at least two adjacent ones of the plurality of blade projections each has an undercut, the undercuts forming a pocket that extends in a peripheral direction;
- the pocket is configured to receive a pair of pins on the blade mount and extend partially around a perimeter surface of the pins;
- and
- the blade mount, which is configured such that the blade is attachable thereto by first setting the blade is-onto the blade mount in the axial direction and subsequently locking the blade with respect to the axial direction at the blade mount by rotating the blade relative to the blade mount and/or by rotating the blade mount relative to the blade, wherein:
- the pins engage the undercuts in the two adjacent ones of the plurality of blade projections to prevent the blade from rotating relative to the blade mount;
- and
- at least one of the pins is preloaded by a spring that causes the pin to move upward into the pocket formed by the undercuts when the pocket is above the pin.
