  • micrometer set screws are used. The attachment of the cutter head to the conical shaft by means of a nut.
  • cutter heads have the disadvantage that they are only comparatively expensive to install, because the cutter head disks are usually only mounted together with the knives on the cutter shaft. Furthermore, the cutter heads are comparatively unhygienic because the material to be cut can settle within the cutter head disc and between the cutter head disc and the blades mounted thereon.
  • the document D2 (DE 304 079 C) discloses a machine for cutting meat, in which two groups of knives are arranged perpendicular to each other so that the cut material is detected by both groups of knives.
  • the knife groups can be removed from the machine as a whole to clean them.
  • the present invention is therefore based on the object to provide a cutter head disc for a meat cutter, which does not have the disadvantages of the prior art.
  • the sheath is made of plastic. This feature of the present invention has the advantage that the cutter head disc has a comparatively low weight, which has a positive effect during transport, during assembly and at high rotational speeds. Furthermore, plastic sheaths are comparatively elastic, so that the knife head discs and the associated knives brace well against each other and sealing.
  • the core has recesses in each of which at least one eccentric retaining bolt for the knife can be attached.
  • a cutter head disc according to claim 1, the recesses, in each of which an eccentric retaining bolt for the knife is attached.
  • the eccentric retaining bolts are preassembled on the cutterhead disk before the cutterhead disk is mounted on the cutterhead shaft.
  • the knife head disk preferably has magnets on which the knife can be fixed to the knife head disk.
  • the cutter head disc according to the invention has a sealing edge, preferably on both sides of the disc.
  • this sealing edge is formed as a raised circular ring.
  • the cutter head disc according to the invention has recesses into which, for example, weights for balancing the weight of the disc together with the knife can be inserted.
  • the cutter head disc has shoulders between which the foot of the knife can be attached.
  • the height of the shoulder is substantially equal to or slightly less than the thickness of the foot of the knife, and more preferably the distance of the shoulders is substantially equal to the width dimension of the foot of the knife.
  • the knife head disc according to the invention has the advantage that no cutting material can penetrate between the preferably metallic core and the plastic sheath. Furthermore penetrates through the sealing edge no cutting material between the cutterhead and the mounted blades, which also represents a significant hygienic advantage.
  • the knife head disc according to the invention can first be mounted on the knife head shaft without a knife. Only then are the knives mounted on the knife head disc and held with the magnets on the knife head disc, before the knife head disc, including knives on the shaft, for example, with a clamping nut, is braced, which is a considerable ease of assembly ..
  • the transport of knife blade including knives is with the knife head disc according to the invention considerably simplified, because the blades and the cutter head disc are easy to disassemble and therefore can be transported separately from each other.
  • the knife head disc according to the invention is simple and inexpensive to manufacture.

  • Another aspect of the present invention is a system consisting of the knife head disc according to the invention, a knife and a filling mat, the knife and the filling plate each having two recesses, preferably bores, are introduced through the eccentric pin.
  • the filler plate is preassembled on the cutterhead disk before the cutterhead disk is mounted on the cutterhead shaft.
  • the filler plate recesses, through which the dynamic imbalance can be compensated.
  • the knives and / or the filling plate with the magnets are reversibly attached to the cutter head disc.
  • This embodiment of the present invention has the advantage that the cutter head disc can be attached to the cutter head shaft without the blades and the blades are subsequently mounted by guiding the recesses of the blades over the eccentric pins and forming a releasable frictional connection between the metallic blade and the magnets ,
  • the cutter head disk or the blades mounted thereon are designed such that the ratio of clamping radius B to cutter radius A is 0.3 to 0.4, preferably 0.37 to 0.38. Further preferably, the ratio of knife radius A to receiving width C is 1.4 to 2.0, preferably 1.6 to 1.7.
  • This preferred embodiment of the system according to the invention has the advantage that the knives withstand higher axial loads and the knife head disc is not formed so large that the volume flow of the cut material is hindered.
  • the system according to the invention has the advantage that no cutting material can penetrate between the metallic core and the casing. Furthermore penetrates through the sealing edge no cutting material between the cutterhead and the mounted blades, which also represents a significant hygienic advantage.
  • Another object of the present invention is a cutter head having a plurality of inventive systems. These systems are arranged one behind the other on a cutterhead shaft and are clamped on the cutterhead shaft with a clamping nut.
  • the knife head according to the invention is particularly suitable for very high rotational speed of the knife tip, preferably> about 145 m / sec.
  • the compensation of the dynamic imbalance takes place in the area of the cutter head disks; i.e. in the knife level. All knives of the knife head have the same length and can therefore be arranged on any knife head disk within the knife head. The knives do not have to be assigned to a specific meat cutter, which greatly simplifies knife logistics. A malfunction of the cutter head by poor balancing is avoided.
  • the cutter head according to the invention is completely self-contained so that no clippings can accumulate between the individual cutter head disks. The cleaning of the cutter head according to the invention can be done without tools after loosening the clamping nut. A static or dynamic balancing of the cutter head according to the invention is generally not carried out.

  • the cutter head is then clamped on the shaft with a clamping screw.
  • cutterhead disks and the blades or filler plates can be preassembled on a sleeve, which is then attached to the cutterhead shaft.
  • the method according to the invention is very simple and very cost-saving and injury-prone to perform for the fitter, since first the knife head disc on the cutter head shaft and then the knife can be mounted to the cutter head disc. Then the next knife head disc is assembled. After the assembly of all cutterhead discs and knives, these need only be clamped by a clamping nut on the cutterhead shaft. During disassembly, the blades are first removed from a knife head disc and then this Knife head disc removed from the shaft. Each knife can be combined with each cutterhead, greatly simplifying assembly and knife logistics. The same knife can even be used in different meat cutters.
  • FIG. 1 shows an embodiment of the cutterhead 1 according to the invention, which consists of a metallic core 2 and a plastic casing 3.
