Assembly of the edge knife on the blade holder. According to a preferred embodiment of the present invention, it is provided that the edge cutter is attached non-positively to the blade holder.

A frictional connection of edge knife and the geometrically adapted blade holder further increases the stability of the device. The at the

Movement of the device occurring forces can hereby be used to fix the edge knife on the knife holder stronger. The increase in the strength of the fixation also reduces the number of required screw connections between edge knife and knife holder, resulting in a reduction of

Setup time of the device leads.

According to a preferred embodiment of the present invention, it is provided that the edge knife and the blade holder are designed such that in the main plane of extension, the difference between outer radius and inner radius of the edge blade is smaller than the radius of the blade holder, so that the edge knife is a narrow edge.

By reducing the blade volume in comparison with the prior art material is saved, which leads to a reduction of the knife weight and this in turn to a simpler and more manageable assembly. There is also a cost reduction through material savings, as well as the ability to use higher quality materials for the edge knife when dealing with costs consistent with prior art devices. Furthermore, the balance is better accomplished by the smaller edge knife and the adjusted blade holder. This can be easily attached to the, compared to the prior art enlarged, knife mount, which brings a significant cost savings.

When, compared to the prior art, constant possibility for absorbing forces acting per screw connection results in a total increased ability to absorb forces acting, in comparison to the prior art, increasing the number of screw. Furthermore, the position of the mounting surface leads to the reduction of mechanical levers, which increases

Reduction of bending, torsion and nutation of the edge knife contributes.

According to a preferred embodiment of the present invention, it is provided that the edge knife has one or more segments, which can be replaced individually.

This makes it possible to partially exchange cutting areas. This is

For example, it makes sense in the area in which the interleaver material is cut. As an interleaver, the person skilled in the art refers to a release sheet, which is usually placed between two sliced food slices. Here is an increased wear of the cutting area. The replacement of individual cutting areas reduces operating costs and reduces maintenance times and is also significant less effort than the entire edge knife to exchange, which improves handling.

According to a preferred embodiment of the present invention, it is provided that the individual segments of the edge knife consist of different materials.

This makes it possible to produce different areas of the edge knife according to their different stress when cutting from different materials. For example, areas in which interleaver material is cut can be made of harder material, which increases the durability of the device.

According to a preferred embodiment of the present invention, it is provided that the connection between two segments takes place in a form-fitting manner.

The forces during start-up, deceleration and rotation of the knife could pull apart the segments of the edge knife. This would create a gap between the segments which creates a small area on the

Device would represent between two cutting areas without cutting function. This would be detrimental to the cut quality of the device. The gap between the segments also comes into contact with food during cutting. However, since the cleaning of the device takes place when the device is stationary, a cleaning of the gap would not be possible, resulting in a hygiene problem. The positive fit could prevent this.

According to a preferred embodiment of the present invention, it is provided that the connection between two or more segments of the edge diameter is non-positively.

The forces which occur when starting, braking and during the rotation of the

Edge knives could pull apart the segments of the edge knife as stated above, the segments pull apart, causing a gap between the segments of the edge knife and in turn causing problems Cutting quality and hygiene leads. A frictional connection solves this problem, in which the forces are used for a stronger connection between the segments.

According to a preferred embodiment of the present invention, it is provided that one or more segments are designed such that they hide the screw connections of one or more other segments.

Food residues on the screw connections could be a hygiene problem. By covering the screw connections, a smooth surface of the device is created, which is easier to clean.

According to a preferred embodiment of the present invention, it is provided that one or more segments of the edge cutter a

have increasing expansion in an axis orthogonal to the main extension plane of the device along an axis of the main extension plane of the device.

Hereby, the cutting material can be given a pulse orthogonal to the cut

Main extension plane of the device given and thus the falling behavior of the cut material are influenced differently depending on the cutting area. For example, when cutting the food slice, a pulse other than the interleaver material could be given.

Embodiments of the invention

FIG. 1 schematically shows a device for slicing

Food bars in food slices according to an exemplary

Embodiment of the present invention shown. The device comprises a removable edge blade 1, preferably made of metal, for cutting the

Food bar and a knife holder 2 for receiving the edge blade 1. The edge knife 1 is asymmetrically shaped in its main extension plane. The blade receptacle 2 is also asymmetrically shaped in its main extension plane, so that it coincides with the shape of the edge cutter 1. The

Knife holder 2 is mounted on a rotor (not shown), so that

Knife holder 2 and edge knife 1 about an axis orthogonal to

Main extension plane of the blade holder 2 are preferably movable, particularly preferably rotatable.

The food bar (not shown) is preferably laterally to the

preferably rotating edge knife 1 out and cut. The assembly of the knife in previous slicing designed by the heavy weight of the knife as difficult. However, a reduction in the weight of the knife is detrimental to the stability of the device. In order to avoid these disadvantages, the device according to the invention provides an asymmetrical shape adapted to the asymmetrical blade geometry

Knife holder 2 before. This increases the stability of the device and simplifies assembly and handling. Furthermore, this complicates the use of knives which are not intended for the knife holder, which reduces the risk of poor cutting results and possible risk to employees and technology.

The inner diameter of the edge blade 1 is significantly increased in comparison to the prior art, the knife is here no knife disc as usual in the art, but an edge knife 1 in the form of a narrow edge. The narrow shape of the edge knife 1 requires a small blade volume, which saves blade material and thus weight. At the same time, however, the stability of the edge blade is maintained. Furthermore, it is also possible to use higher quality materials at a constant cost.

Due to the enlarged inner diameter of the edge blade 1 is the

Anschraubfläche for the screw 3 for fixing the edge blade 1 on the blade holder 2 increases. The compared to previous ones

Slicing significantly larger An r looted surface and significantly increased number of fittings 3 increases the stability of the device. The enlarged with the inner diameter of the edge diameter 1 knife holder 2 leaves in the present invention more space for balancing the device, which is preferably mounted on the main extension plane of the blade holder 2 (not shown). This simplifies balancing and reduces their costs.

The connection (not shown) of edge knife 1 and knife holder 2 is preferably positive fit. This further increases the stability of the device and simplifies its assembly. Furthermore, a preferred embodiment of the invention provides the frictional connection of edge cutter 1 and knife holder 2. In this case, the forces occurring during the movement of the device are used to further increase the stability of the device. The edge knife 1 has one or more segments 10 and 11, each of which forms its own cutting area. The segments 10 and 11 can be replaced individually. This has the advantage compared to the previous slicing apparatus that areas which are particularly heavily stressed, for example the cutting areas in which interleaver material is cut, are more often

can be exchanged.

In order to meet the different load on the cutting areas, the individual segments 10 and 11 of the edge blade are made of different

Materials executed. Thus, the edge knife segment 11 of the heavily stressed area in which the interleaver material is cut is made of a particularly hard material. This is particularly maintenance-friendly and cost-effective, since at the same time longer durability expensive high-quality material is used only there, if it is needed.

FIG. 2 schematically shows a section orthogonal to the main extension plane through two edge cutter segments 4 and 5. The edge cutter segments 4 and 5 are positively connected to each other. Through this form-fitting prevents a gap between the individual edge cutter segments 4 and 5 is formed during operation by the forces acting on the rotation or the start-up of the machine. This would adversely affect the quality of cut and could lead to hygiene problems due to the deposition of food residues.

FIG. 3 schematically shows a section orthogonal to the main extension plane through two edge cutter segments 6 and 7. The segments 6 and 7 of

Edge knife point along an axis of the main plane of extension
