Abstract

An electrically-operated slice-cutting machine for cutting slices off—in particular, strand-shaped—material to be cut—preferably, food—includes: a machine housing which holds a drive motor and a rotating and/or circumferentially-movable cutting blade driven by the drive motor; a product feed for feeding the material to be cut to the cutting blade; a carrier plate; and a cutting frame arranged on the carrier plate and via which the material to be cut is fed to the cutting blade. The cutting frame is geometrically arranged such that the material to be cut is feedable by the product feed through the cutting frame to the cutting blade in an operating state of the slice-cutting machine. The slice-cutting machine has at least a first and a second lever element for releasably fixing the cutting frame, each of the two lever elements being transferrable from a holding position into a release position.

First claim

What is claimed is:

1. An electrically-operated slice-cutting machine for cutting slices off material to be cut, the slice-cutting machine comprising:
a machine housing which holds a drive motor and a rotating and/or circumferentially-movable cutting blade driven by the drive motor;
a product feed configured to feed the material to be cut to the cutting blade;
a carrier plate; and
a cutting frame arranged on the carrier plate and via which the material to be cut is fed to the cutting blade,
wherein the cutting frame is geometrically configured such that the material to be cut is feedable by the product feed through the cutting frame to the cutting blade in an operating state of the slice-cutting machine,
wherein the slice-cutting machine has at least a first and a second lever element configured to releasably fix the cutting frame, each of the two lever elements being transferrable from a holding position into a release position by a movement mechanism, each of the two lever elements in the holding position abutting the cutting frame,
wherein the cutting frame is fixable to the carrier plate by the lever elements in the holding position,
wherein, in the release position, the first and second lever element are spaced apart from the cutting frame, and
wherein the cutting frame is releasable from the carrier plate without tools,
wherein the cutting frame in connection with the carrier plate is self-centering, and
wherein the cutting frame and the carrier plate have beveled surfaces abutting each other in a form-fitting manner.

2. The slice-cutting machine according to claim 1 , wherein the movement mechanism has a pivot mechanism and/or a folding mechanism of each of the first and second lever element.

3. The slice-cutting machine according to claim 1 , wherein at least one of the lever elements is pivotable about a pivot point from the holding position into the release position.

4. The slice-cutting machine according to claim 1 , further comprising at least one securing block which at least one of the lever elements in the holding position abuts,
wherein the securing block is arranged in a movement direction of the lever element from the holding position into the release position.

5. The slice-cutting machine according to claim 4 , wherein the securing block is attached to a blade hood of the slice-cutting machine.

6. The slice-cutting machine according to claim 4 , wherein at least one of the lever elements has a tab which abuts the securing block in the holding position of the lever element.

7. The slice-cutting machine according to claim 6 , wherein the securing block, in the release position of the lever element, is movable against the tab of the lever element and thereby prevents closing of the machine housing, and
wherein at least a part of the lever element with the tab is arranged in the release position at a position at which the securing block is located in the holding position of the lever element.

8. The slice-cutting machine according to claim 1 , wherein at least one of the lever elements comprises a rocker with a support, and a spring is arranged on the at least one of the lever elements, and
wherein the spring is tensionable by pivoting the lever element from the holding position.

9. The slice-cutting machine according to claim 1 , wherein the cutting frame has a groove in which the lever elements engage in the holding position.

10. The slice-cutting machine according to claim 1 , wherein at least one of the lever elements comprises a tensioning lever element.

11. The slice-cutting machine according to claim 1 , wherein the machine housing has a closure-monitoring sensor, and
wherein the slice-cutting machine is startable only when the machine housing is closed.

12. The slice-cutting machine according to claim 1 , wherein the cutting frame has a bevel, a stepped supporting surface for the lever elements, and/or a stepped contour for positioning on the carrier plate.

13. The slice-cutting machine according to claim 1 , wherein the carrier plate is rigidly connected and screwed to the machine housing.

14. An electrically-operated slice-cutting machine for cutting slices off material to be cut, the slice-cutting machine comprising:
a machine housing which holds a drive motor and a rotating and/or circumferentially-movable cutting blade driven by the drive motor;
a product feed configured to feed the material to be cut to the cutting blade;
a carrier plate; and
a cutting frame arranged on the carrier plate and via which the material to be cut is fed to the cutting blade,
wherein the cutting frame is geometrically configured such that the material to be cut is feedable by the product feed through the cutting frame to the cutting blade in an operating state of the slice-cutting machine,
wherein the slice-cutting machine has at least a first and a second lever element configured to releasably fix the cutting frame, each of the two lever elements being transferrable from a holding position into a release position by a movement mechanism, each of the two lever elements in the holding position abutting the cutting frame,
wherein the cutting frame is fixable to the carrier plate by the lever elements in the holding position,
wherein, in the release position, the first and second lever element are spaced apart from the cutting frame, and
wherein the cutting frame is releasable from the carrier plate without tools,
wherein the cutting frame is shaped to be precisely positioned in the carrier plate, and
wherein the cutting frame has a beveled corner.
