Description

The invention is based on a knife holder for a cutting knife of a sausage cutting machine, comprising an arm on which a support surface is formed which is set up in such a way that a twisting point to be cut between two sausages of a sausage chain to be cut is on the support surface before the cut Support can come and the sausages to be separated are located on opposite sides of the support surface, in particular lying and / or hanging.

Such a knife holder is from the DE 100 15 664 A1 known.

The content of the document DE 100 15 664 A1 , in particular the description, the claims, the drawing and the abstract, form part of the present description by express reference, unless otherwise stated in what is described below and / or in the accompanying drawing.

Such knife holders are used in particular for cutting knives that are used in sausage cutting machines that separate sausages of a sausage chain from one another according to the random principle by means of a drum provided with cutting blades.

The object of the present invention is to provide a knife holder, a cutting knife and a sausage cutting machine, by means of which the sausages of a sausage chain to be cut can be separated from one another particularly efficiently.

The object is initially achieved by a knife holder for a cutting knife of a sausage cutting machine, comprising an arm on which a support surface is formed which is set up in such a way that a twisting point to be cut between two sausages of a sausage chain to be cut is on the support surface before the cut can come to rest and the sausages to be separated are located on opposite sides of the support surface, in particular can lie and / or hang, the support surface having at least one indentation.

The invention is based on the knowledge that, particularly in the case of longer sausage chains, twist-off points that are not located in the center of the sausage chain, but off-center twist-off points on the support surface are often used. In this case, the remaining chains of the sausage chain hanging down on both sides of the support surface are of different lengths and thus of different weights. As a result, it often happens that the sausage chain slips off to the side of the longer remaining chain. In this way, the relevant twist-off point cannot be fed to a cutting edge of the cutting knife, at least in this passage, so that the relevant twist-off point is not severed in this passage. It is therefore necessary to catch the sausage chain again, in particular accidentally, at this twisting point by means of this or another cutting knife of the sausage cutting machine.

The invention intervenes here in that, according to the invention, the bearing surface has at least one indentation. As a result of the indentation, one, in particular the shorter, remaining chain can be prevented from sliding over the support surface so that the sausage chain does not slip off the cutting knife before the relevant twisting point is cut.

This increases the probability that a twisting point of a sausage chain that has got caught on the cutting knife, in particular on the knife holder, is actually fed to the cutting edge of the cutting knife to separate the two sausages in question. The overall efficiency of a sausage cutting machine can thus be increased.

The terms “sausage” and / or “sausage chain” can be understood very broadly. In particular, these terms can be interpreted to represent foods or chains of foods that are usually arranged in chains and later to be separated, at least in the context of their production. In particular, it is conceivable to subsume sausage products of any type and / or size under the term “sausage” and / or chains of such sausage products under the term “sausage chain”.

An inlet edge can be formed on the arm of the knife holder, in particular along part of the arm. The inlet edge can be set up to guide a sausage chain caught on the knife holder, in particular on the arm, to the cutting edges. For this purpose, the support surface can preferably extend into the inlet edge or over the inlet edge.

Since sausages of a sausage chain usually have a circular or at least substantially circular cross-section, it is preferred if the at least one indentation has a circular arc-shaped or at least substantially circular arc-shaped cross section.

If sausage chains with sausages of different thicknesses are processed on a sausage cutting machine, it is advantageous if the longest chord of the at least one indentation is shorter than the smallest diameter of the sausages to be cut Sausage chain is. It can thus be ensured that a sausage chain with thin or with the thinnest sausages to be separated can also be processed efficiently.

The knife holder can be manufactured inexpensively if it is made at least partially from plastic, preferably from polyethylene. Weight advantages can also be achieved through such a knife holder. This can be particularly important when a large number, for example between 20 and 100 or even more than 100, of cutting knives are used in a sausage cutting machine.

For this purpose, it is particularly conceivable that the knife holder or at least part of the knife holder is manufactured as an injection-molded part, preferably as a plastic injection-molded part.

The knife holder can preferably be in two parts. The knife holder can then be formed from two parts, in particular parts that are mirror-symmetrical to one another, in particular shell-shaped parts. One or more blades of the cutting knife can then be enclosed between the two parts of the knife holder, in particular clamped, glued in and / or cast. However, a one-piece knife holder is also conceivable.

A cutting knife of a sausage cutting machine, comprising a knife holder according to the invention and at least one blade, the at least one blade preferably being mounted in the knife holder, also falls within the scope of the invention.

Due to the knife holder according to the invention, the probability that a sausage chain to be separated slips off the cutting knife before it is cut can be reduced, so that the probability that the sausage chain is separated, and thus the efficiency of a sausage separating machine equipped with such a cutting knife, can be increased .

In particular, a tapering gap can be formed by means of at least one cutting edge of the at least one blade. For this purpose, one or more cutting edges can be formed on at least one of the blades. One or more cutting edges of one or more blades of the cutting knife can overall form the tapering gap. The tapering gap can form an insertion gap for two sausages to be separated from one another in a sausage chain. With such a cutting knife, the twisting point to be separated of the two sausages of the sausage chain to be separated can be fed to the tapering gap so that it can then be separated from the at least one cutting edge, in particular driven by gravity by the weight of the sausage chain.

Due to food hygiene requirements, in a particularly preferred class of embodiments of the cutting knife it is provided that the blade has at least one recess within an interface between it and the knife holder. The recess can be penetrated by a sealant, an adhesive and / or a plastic. In particular, in the case of a knife holder manufactured by means of plastic injection molding, plastic, in particular the knife holder's own material, can also penetrate the recess. Gaps between the blade and the knife holder in the area of the interface can thus be minimized or prevented. In particular, the area of the interface can be sealed. Thus, water and / or residues of the cut material to be processed, in particular sausages, cannot adhere to the knife holder and / or to the blade. This also makes cleaning the cutting knife easier.

The scope of the invention also includes a sausage cutting machine comprising a drum on and / or in which at least one cutting knife according to the invention is formed and / or arranged. A cutting knife according to the invention is thus used in such a sausage cutting machine. By using this cutting knife, the probability that a sausage chain caught on the knife holder of the cutting knife will actually be separated can be increased. The number of rotations of the drum required to completely cut all twisting points can thus be reduced, which ultimately allows the overall efficiency of the sausage cutting machine to be increased considerably.

Further advantages of the invention, in particular the knife holder, the cutting knife and the sausage cutting machine, emerge from the aforementioned document incorporated by reference in this description, from the following description of exemplary embodiments of the invention with reference to the figures of the drawing, which shows details essential to the invention , as well as from the claims.
In the schematic drawing, exemplary embodiments of the invention are shown and explained in more detail in the following description.

• 4th a sausage cutting machine in a schematic representation from the front.

To facilitate understanding, the same reference numerals are used for corresponding elements in the figures. As far as possible, the reference numerals of the publication, which is incorporated by reference, are used for corresponding elements in the following.

1 shows a cutting knife 1 with a knife holder 3 in which a blade 2 with two cutting edges 4th is recorded.

The two cutting edges 4th the blade 2 form an acute angle.

The knife holder 3 has an arm 10 on. On the arm 10 is a leading edge 7th educated. In particular, the leading edge runs 7th from a point in the area of a free end of the knife holder 3 right down to the cutting edges 4th the blade 2 .

Along the leading edge 7th extends a support surface 8th . The supporting surface 8th extends in particular into the leading edge 7th inside.
The supporting surface 8th is set up to record twisting points to be cut between at least two sausages to be separated in a sausage chain before they are separated.

The supporting surface 8th has several indentations, of which two indentations are exemplary 12 , 12 ' in 1 are marked with a reference number. The indentations 12 , 12 ' have an arcuate cross section. In particular, the indentations 12 , 12 ' a substantially semicircular cross-section.

The longest tendons 14th , 14 ' of the indentations 12 , 12 ' are of different lengths. In particular, the two are the longest tendons 14th , 14 ' shorter than the smallest diameter of the sausages to be cut of the sausage chains that are processed on a sausage cutting machine in which the in 1 shown cutting knife 1 should be used is.

The knife holder 3 is manufactured as a plastic injection molded part. It consists of two half-shells, between which the blade 2 is jammed.

2 shows the cutting knife 1 according to 1 in a perspective view obliquely from the front. The multiple indentations can again be seen, two of which are in turn 12 , 12 ' are provided with reference numerals.

It can also be seen that the support surface 8th the knife holder 3 has a certain width. In particular, the width of the support surface 8th or the leading edge 7th adapted to the expected length of the turning points to be cut.
3 shows a schematic view of one of the two half-shells of the knife holder 3 of the cutting knife 1 with their contact surface 8th .

The supporting surface 8th has several indentations, two of which in turn with the reference numerals 12 , 12 ' are provided.

The view according to 3 also leaves the arrangement of the blade 2 on the half-shell or in the knife holder 3 detect.

In the area of an interface 13 inside the knife holder 3 and in the area of the blade 2 extends and through one along the edge of the knife holder 3 formed boundary line 5 is limited, it can be seen that the blade 2 has a plurality of elongated recesses, one of which is an example 6th is marked with a reference number.

The recesses 6th are designed as elongated holes. Through the recesses 6th is plastic during the manufacture of the cutting knife 1 , especially during the manufacture of the knife holder 3 by means of plastic injection molding.

The gap along the border line 5 between the blade 2 and the one in the area of the border line 5 located knife holder 3 is thereby sealed. In particular, neither leftover food nor water can move along the borderline 5 in the intermediate area between the blade 2 and the knife holder 3 crawl in and / or lay down there.

4th shows a sausage cutting machine 16 . The sausage ripper 16 has a drum 18th on. The sausage chains are placed in this drum to separate twisting points from sausage chains 18th given. Then the drum 18th set in rotation.

The drum 18th has a large number of cutting knives on the inside 1 on, one of which is provided with a reference symbol by way of example. Preferably at least one of the cutting knives corresponds 1 the drum 18th one of the related to 1 to 3 previously described cutting knife 1 .

It can be seen that the cutting knife 1 obliquely from the inside of the drum 18th protrude. This arrangement allows sausage chains, in particular, on the knife holders 3 ( 1 ) the cutting knife 1 caught and in the area of the respective blade 2 ( 1 ) of the cutting knife 1 get in and be separated there.

Because of the indentations 12 , 12 ' ( 1 ) of the support surface 8th ( 1 ) this separation takes place with increased probability, so that the sausage separating machine 16 can have a particularly high efficiency.
