Description

(1) A preferred example embodiment of a set of cutters according to the invention is described in further detail below with the aid of the drawings. There are shown:

(2) FIG. 1 a lateral view, partially in section, of a mincer worm with a set of cutters in place;

(3) FIG. 2 an enlarged lateral view of a cutter holder with cutter of the set of cutters of FIG. 1;

(4) FIG. 3 a top view onto a cutter of the set of cutters of FIG. 1.

(5) FIG. 1 shows a set of cutters 10, which in the illustrated example has two perforated discs 12, 14 with cutter holders 11, 13 arranged respectively in front. The set of cutters 10 is placed onto a shaft 15 of a mincer worm 16, wherein the cutter holders 11, 13 are driven in a rotating manner jointly with the worm 16. In the illustrated example, the perforated discs 12, 14 have two radially spaced rows of holes 17, 18 or respectively 19, 20.

(6) The cutter holders 11, 13 have three wings, of which two wings 21, 22 or respectively 23, 24 are to be seen in the lateral view. Each wing 21, 22, 23, 24 carries a cutter 25, 26, 27, 28, the shape and mounting of which are described in greater detail by means of the enlarged illustration of the cutter holder 11 in FIG. 1 and by means of FIG. 2. In the illustrated example, the wings 21, 22, 23, 24 are of equal length and are preferably spaced apart from one another respectively by 120. The axes R (FIG. 2) of the cutters 25, 26, 27, 28 therefore lie on a circle around the shaft axis W, so that the cutters 25, 26, 27, 28 are moved over the rows of holes 17, 18, 19, 20, when the cutter holders 11, 13 rotate about the shaft axis W of the mincer. The cutters 25, 26, 27, 28 could, however, also lie on different circles. FIG. 1 illustrates in addition that the cutters 25, 26, 27, 28 in the unstressed state are arranged with a small axial distance a in front of the perforated discs 12, 14, when no material which is for cutting is to be processed. The mincer with the set of cutters 10 according to the invention can therefore also run in a wear-free manner without material.

(7) FIG. 2 illustrates the mounting of the cutters 25 to 28 in the cutter holders 11, 13 using the example of the cutter 26. The cutter 26 has a round foot 29, which is inserted into a round through-bore 30 in the wing 21 and is mounted there by a sealing ring 31 so as to be axially movable and rotatable. The foot 29 can carry out, in addition, limited tilting movements in the through-bore 30, which is somewhat larger in diameter, so that the cutter 26 is additionally mounted in a floating manner in the cutter holder 11. Through the simple plug-in connection between cutter 26 and cutter holder 11, an easy installation and exchangeability of the cutter 26 is provided. The sealing ring 31, in addition, prevents the penetration of pieces of meat.

(8) The cutter 26 has in addition a relief area E, the size of which depends on the material which is for cutting.

(9) The axial mobility enables a pressing of the cutter 26 against the perforated disc 12 by the material for cutting, which is transported up thereto in arrow direction 32. Through the floating mounting, the cutter can then also lie here with the entire surface against the perforated disc 11, if this is not aligned exactly parallel to the cutter holder 11. In addition, the material which is for cutting can set the cutter 26 in rotation, whereby a very good cut quality is produced, as tests have shown. The material which is held secure by the openings 19, 20 of the perforated disc 12 is in fact cut at a distinctly higher percentage and not ground by crushing, as is the case in conventional sets of cutters.

(10) As FIG. 3 shows, the cutter 26 has three wings 33, 34, 35, which carry blades 36, 37, 38 respectively on their outer periphery, which in the illustrated example are provided with a serrated edge. The blades 36, 37, 38 are configured in the form of a circular arc and all have the same radial distance to the rotation axis A of the cutter 26. The illustrated cutter shape here is only by way of example. The cutter 26 could also be round, i.e. could have no wings 33, 34, 35 and could carry a circular or polygonal blade. The shape of the cutter 26 can be selected according to the material for cutting which is to be processed and the end product which is to be produced. Through the simple plug-in connection between cutter 26 and cutter holder 11, the cutters can be quickly exchanged for cutters of a different shape.
