Abstract

A whetting device for a slicer has a whetstone for sharpening a circular blade of the slicer; a hone for deburring the blade; a handle for moving the whetstone or hone toward the blade; a mount fastenable to a stop plate of the slicer, having an insertion apparatus for form-fittingly insertion into the stop plate, a U-shaped plate receptacle which has a gap for introducing the stop plate into the gap when the whetting device is pushed onto the stop plate; a receptacle for engaging around an end of the blade guard ring when the stop plate is a predetermined distance from the circular in the direction of rotation of the blade, and not to engage when shorter than that distance between; and a frame covering a cutting edge of the circular blade and for pivoting the whetting device into a working position.

First claim

The invention claimed is:

1. A whetting device for a slicer for slicing off slices from a length of material to be sliced, the whetting device comprising:
a whetstone configured to sharpen a circular blade of the slicer, the circular blade being configured to rotate or be movable in a circulating manner;
a hone configured to deburr the circular blade;
a handle configured to move the whetstone or the hone toward the circular blade;
a mount configured to be fastened to a stop plate of the slicer having an insertion apparatus for being form-fittingly inserted into the stop plate, the mount having a U-shaped plate receptacle which has a gap for introducing the stop plate into the gap in a state where the whetting device is pushed onto the stop plate;
a receptacle configured to form-fittingly engage around an end of a blade guard ring of the slicer, the receptacle being configured to engage around an end of the blade guard ring in a state where the stop plate is at least at a predetermined distance from the circular blade in a direction of an axis of rotation of the circular blade, and not to engage around the end of the blade guard ring in a state where the distance between the stop plate and the blade guard ring is shorter than the predetermined distance in the direction of the axis of rotation of the circular blade; and
a frame configured to cover at least one portion of a cutting edge of the circular blade and to pivot the whetting device from an installation position into a working position.

2. The whetting device according to claim 1 , wherein the insertion apparatus comprises at least one lug configured to engage in an associated recess in the stop plate, the at least one lug being configured to engage in the recess on a rear face of the stop plate, and the rear face of the stop plate facing away from a carriage of the slicer in the direction of the axis of rotation of the circular blade.

3. The whetting device according to claim 1 , wherein the receptacle is a cut-out for introducing the end of the blade guard ring.

4. The whetting device according to claim 1 , wherein the frame of the whetting device comprises cover plates configured to cover the cutting edge of the circular blade, the whetstone and the hone arranged between the cover plates.

5. The whetting device according to claim 1 , further comprising a latching mechanism configured to lock the whetting device in the working position or in the installation position.

6. The whetting device according to claim 1 , further comprising a pivot mechanism configured to pivot the whetting device from the working position into the installation position.

7. The whetting device according to claim 6 , further comprising a stop for the pivot mechanism.

8. The whetting device according to claim 1 , wherein the mount for fastening the whetting device to a stop plate of the slicer has a threaded spindle for clamping the stop plate.

9. The whetting device according to claim 1 , wherein the insertion apparatus is on the inner surface of the gap of the plate receptacle.

10. The whetting device according to claim 1 , wherein the insertion apparatus has a tapering shape in a direction of the insertion.

11. The whetting device according to claim 1 , wherein the handle for moving the whetstone or the hone toward the circular blade of the slicer is a wheel of the frame of the whetting device, the wheel being configured, when turned, to move the whetstone and/or the hone toward the circular blade, such that they can be arranged on the circular blade, and/or to move them away from the circular blade.

12. A slicing system comprising, the slicing system comprising:
a slicer for slicing off slices from a length of material to be sliced, the slicer comprising:
a slicer housing, which retains a drive motor and a circular blade that is driven by the drive motor and is rotatable or is movable in a circulating manner, a cutting edge of the circular blade being covered in a first portion by a blade guard ring;
a stop plate; and
a displaceably arranged carriage, which is configured to feed the material to be sliced to the circular blade, the stop plate being movable in a direction of an axis of rotation of the circular blade; and

a whetting device configured to whet the circular blade, the whetting device comprising:
a whetstone configured to sharpen the circular blade and a hone for deburring the circular blade, the whetting device having a handle for moving the whetstone and/or the hone toward the circular blade;

a mount configured to be fastened to the stop plate having an insertion apparatus configured to be form-fittingly inserted into the stop plate, the mount having a U-shaped plate receptacle that has a gap for introducing the stop plate into the gap in a state where the whetting device is pushed onto the stop plate;
a receptacle configured to form-fittingly engage around an end of the blade guard ring, the receptacle being configured to engage around the end of the blade guard ring in a state where the stop plate is at a predetermined distance from the circular blade in a direction of an axis of rotation of the circular blade, and the receptacle being configured not to engage around the end of the blade guard ring in a state where the distance between the stop plate and the blade guard ring is shorter than the predetermined distance in the direction of the axis of rotation of the circular blade; and
a frame configured to cover a second portion of a cutting edge of the circular blade and configured to pivot the whetting device from an installation position into a working position.

13. The slicing system according to claim 12 , wherein the stop plate of the slicer has at least one recess, for form-fittingly receiving the insertion apparatus of the whetting device, the recess being formed on a rear face of the stop plate, the rear face facing away from a carriage of the slicer in the direction of the axis of rotation of the circular blade.

14. The slicing system according to claim 12 , wherein a width of the frame in the direction of the axis of rotation of the circular blade is such that the frame always covers the cutting edge of the circular blade while the stop plate is in motion.

15. The slicing system according to claim 12 , wherein the stop plate of the slicer is moveable into a zero position in which the stop plate and the blade guard ring together fully cover the cutting edge of the circular blade such that the circular blade does not slice the material to be sliced.
