Definitions

  • the invention relates to a meat cutter according to the preamble of claim 1.
  • Meat cutters are used in meat processing for the comminution and mixing of meat products, especially in sausage production.
  • Such meat cutters usually have a ring bowl, in which a rotating cutter head is arranged with several cutter knives.
  • the ring bowl rotates here about an axis perpendicular to the axis of rotation of the cutter head axis, so that the material to be processed is supplied by the rotation of the ring bowl in the work area of the cutter head.
  • Knife heads have already become known for such meat cutters (cf. DE 37 35 651 A1 ), in which two cutter knives are arranged in a plane. Such cutter knives are usually fastened with bolts or the like to traction sheaves, which are rotatably mounted with a hexagon socket on a drive shaft of the Fleischkutters with external hexagonal profile.
  • meat cutters with cutter heads are known in the trade, in which the knife on a round shaft with Help from keyways and feather keys are attached. Also, a star-shaped wave profile with two mutually offset hexagonal profiles is used in commercial cutter heads.
  • the object of the invention is in contrast to propose a meat cutter, a cutter head and associated cutter knives, in which these disadvantages are avoided or reduced.
  • This object is based on a meat cutter of the aforementioned type by the characterizing features of claim 1.
  • a meat cutter is characterized in that the cutter head comprises at least two cutter knives arranged in a plane, wherein at least two separate cutter knives lying opposite one another are provided or wherein the two cutter knives arranged in one plane are designed as double knives.
  • the toothing structure can be arranged on the circumference of the drive shaft so that after fixing the mating toothings by pushing in the axial direction the knife not only rotatably, but is also secured against removal in the radial direction.
  • At least two cutter knives arranged in a plane are provided in a cutter head according to the invention.
  • Such an arrangement requires a smooth running without major imbalances and thus reduces the load on the drive shaft.
  • two cutter knives arranged in a plane can be designed as double knives.
  • a double knife in which the knife feet are centrally connected in one piece, is more difficult and more dangerous to handle than a single knife due to the larger mass and the existing sharp edges on both sides.
  • the fixation of such knives according to the invention in turn facilitates handling and improves the working safety, so that a double knife in this embodiment is easier and safer to use than in conventional meat cutters.
  • a holding element is provided, which is provided between the knife foot or the knife feet and the drive shaft and which the Having the toothing structure of the knife matching tooth structure.
  • Such a support member is formed according to the invention as a sleeve which extends in the axial direction over several planes of the knife.
  • a sleeve has the advantage that only a single support member must be inserted before mounting the knife on the drive shaft and thus the tooth structure is provided for fixing a plurality of knives in different planes in one operation.
  • the support profile with a Hexagon socket and / or a keyway for the rotationally fixed connection by means of a feather key, so that the toothing structure according to the invention, as already indicated above, can be used in commercially available and in particular already existing meat cutters.
  • At least the toothing structure is provided on the side of the drive shaft with a uniform circumferential distribution. This is particularly advantageous when using a retaining sleeve for the formation of the drive-side toothing structure, since with a circumferential even distribution of the desired angular displacement between the individual knife levels can be achieved without additional measures by pushing the knife in the desired angular position.
  • the tooth structure is advantageously constructed so that a uniform division over the outer circumference or an angular range of 360 degrees results.
  • a uniform angular offset of one or more pitch angles of the cutter blades in the construction of the cutter head is possible.
  • the knife feet also have a uniform circumferential distribution of the tooth structure over the angular range covered by them.
  • tooth structures In order to bring about the telescoping of the tooth structures in the axial direction not only a rotationally secure attachment, but also a fixation in the radial direction, in any case tooth structures must be selected with a correspondingly large angular distance and / or a corresponding configuration of the individual gears, so that after the placement of the knife in the axial direction and a radial fixation is ensured, which is in particular also able to absorb the centrifugal forces occurring during rotation of the cutter head.
  • Such a radial fixation can be achieved, for example, in that the individual toothings of the toothing structure are at least partially undercutting in the radial direction.
  • a radial fixation is effected by each individual toothing. This embodiment therefore provides a increased stability against radial centrifugal forces.
  • one or more spacers are further provided in the axial direction for axial displacement of different blade levels. This makes it possible to achieve a proven structure with desired axial offset with regard to the axial arrangement of the knife.
  • These spacers can have inside a circular Auf originallyung, since they do not interact with the tooth structure, such as a support sleeve interact.
  • an initial friction ring and / or a closing ring for axially securing the cutter head to the drive shaft are additionally provided.
  • These rings which can be fixed on the drive shaft in a conventional manner, for example, clamped or screwed, provide on the one hand for the axial positioning of the cutter head and beyond for the Cohesion of the different levels of the assembled cutterhead in the axial direction.
  • the spacers, the initial driving ring and / or the closing ring are provided with weight-reducing structures, for example with material recesses, in order to reduce the total weight of the cutter head.
  • a gearing according to the invention it is also possible to provide knife levels with only one cutter knife. This is advantageous, for example, in the catchment area of the material to be processed in order to improve the intake of the material into the cutter head and to avoid a build-up of material.
  • This single knife can be readily constructed identical to the other cutter knives.
  • FIG. 1 shows a cutter knife 1 with a knife base 2 and three mutually angled arranged cutting 3, 4, 5.
  • the knife base 2 shows a straight edge 6 and a semicircular recess 7.
  • the circumference is in the recess 7, a tooth structure 8, consisting of projections or teeth 9 and recesses or gaps 10 attached.
  • a cutter knife 1 can be fastened on a drive shaft.
  • FIG. 2 shows the arrangement of a knife plane on a drive shaft of a Fleischkutters in plan view.
  • Two cutter knives 11, 12, which may be formed, for example, according to the cutter knife 1 each have a blade base 2, as he said FIG. 1 has been described.
  • These knife feet 2 are connected with their tooth structure 8 with a support member 13, wherein the support member 13 is formed sleeve-shaped.
  • the holding element 13 in turn has a toothed structure 14 with teeth 15 and gaps 16 which fits the toothing structure 8.
  • the support member 13 is provided with a hexagonal profile 17, which is designed to match a corresponding external hexagonal profile 18 of a drive shaft 19.
  • the support member 13 is rotatably mounted on the drive shaft 19.
  • the support member 13 in the axial direction, i. pushed onto the drive shaft 19 perpendicular to the plane of representation.
  • the two cutter knives 11, 12 with their knife feet 2 also in the axial direction, i. are brought perpendicular to the plane of representation in the illustrated installation position, wherein the teeth 9 of the toothed structure 8 of the knife feet 2 engage in the gaps 16 of the toothed structure 14 of the support member 13 and vice versa, i. the teeth 15 of the support member 13 engage in the gaps 10 of the knife feet 2.
  • FIG. 3 shows a perspective view of a partially constructed cutter head.
  • the support member is a support sleeve 21 having an axial length that extends over a plurality of blade planes.
  • This support sleeve 21 has a hexagon socket 17, so that it in the manner described rotationally fixed to the hexagon profile 18 of the drive shaft 19 can be plugged.
  • the holding sleeve 21 shows a toothing structure 14 according to the embodiment according to FIG. 2 ,
  • the cutter knives 11, 12 are already shown in the assembled position, after they in axial Direction A were pushed onto the support sleeve 21.
  • FIG. 4 shows three components of another embodiment, ie an initial drive ring 22, a support plate 23 and cutter knives 24, 25, the knife feet 26 are formed with one of the above-toothing structure similar tooth structure 26 consisting of teeth 27 and gaps 28.
  • FIG. 5 shows a section of the support sleeve 21 in plan view, in particular, the teeth 9 and gaps 10 are better recognizable in their profile.
  • the parallel configuration of the side edges 29, 30 of the teeth 9 or gaps 10 can be seen. This means that the toothed structure 9 is designed directed radially outward without being undercut of the individual teeth.
  • FIG. 6 shows a plan view of another support member 31, which is formed according to the sleeve sleeve 21 sleeve-shaped for several levels knife.
  • the gaps 32 are semicircular in this embodiment, so that the side edges of the teeth 33 have the shape of circle segments. This type of toothing is aligned in the radial direction and not undercutting the individual teeth.
  • the shape of the tooth structure 34 is as shown in FIG. 4 such that the teeth 35 have a radius which leads to an undercut shape of the individual teeth.
  • All shown toothing structures 8, 14, 26, 34 are suitable for the inventive construction of a cutter head.
  • the radial hold can be increased by an undercut shaping of the individual teeth and gaps, for example, according to the teeth 35 and gaps 36.
