Definitions

  • the invention relates to a knife with at least two wings rotatable about a common axis for processing a strand of meat into slices.
  • the meat strand is aligned parallel to the axis of the knife and can be moved in the longitudinal direction.
  • Each wing of the knife is provided with an arcuate cutting edge, the effective cutting length of which corresponds at least to the maximum diameter of the meat strand.
  • Knives of this type are generally known (see DE-U-86 27 902) and make it possible, even with constant angular velocity of the wings, to guide the cutting edges across the meat strand at different feed speeds.
  • the feed rate can be kept correspondingly low, for example at the beginning of a cut with a large tendency to deform the meat strand, then increased in the further course of the cut depending on the reduced tendency to deform the meat strand and finally reduced again towards the end of the cut when the tendency to deform the meat strand increases again.
  • a preferred area of application for a double-winged knife is, however, a device for dividing a chop strand into chop slices. It is Usually, the knife is driven by an electric motor which is connected to the shaft of the knife via a worm gear.
  • the worm gear for example, has a gear ratio of 1: 8, so that a blade speed of approximately 180 rpm is achieved at an engine speed of 1500 rpm.
  • considerable rotational energy is stored within the drive system, since the electric motor has a relatively large moment of inertia, which has a corresponding effect on the storable energy at high speeds. Without this stored energy, the installed power of the electric motor alone would not be sufficient to split the bone with the knife hitting a chop bone.
  • the rotational energy can also cut a bone in the cutting plane of the knife.
  • the known knife is to be used in a device which is provided with a hydraulic motor as the drive, there is inevitably no rigid connection between the hydraulic drive and the knife shaft. Due to the lower speed of the drive system, in particular it is not possible to introduce sufficient rotational energy into the system.
  • the invention has for its object to design a knife of the type described above so that so that considerable rotational energy can be stored even at low speeds, and the blades of the knife should also experience substantial stabilization.
  • the additional mass according to the invention not only significantly increases the moment of inertia of the knife, but also fixes the individual blades of the knife. If, according to one embodiment of the invention, the additional mass consists of a ring connecting the free ends of the wings and concentric to the axis, the knife is thereby given an overall stable design which, when processing a meat strand, favors the accuracy of shape, in particular with regard to a uniform thickness of the resulting slices.
  • an additional mass segment can be arranged on the ring in the connection area of each wing.
  • the mass moment of inertia of the knife can be significantly increased by the additional mass segments increase, without the ring itself having to be made from a relatively wide profile, which could make the disassembly and reassembly of the knife more difficult, because usually the strand to be processed is passed through a groove which has a relatively narrow transverse gap to pass through it pass the knife blades so that the ring runs around the guide trough and must pass through the gap to disassemble and reassemble the knife.
  • the wings can either be made with one blade from a knife blank or can consist of individual parts which are held in position by a shaft which rotates the knife and the ring.
  • each wing may be advisable to provide each wing with a square opening, the inner contour of which corresponds to the outer contour of the shaft in the arrangement area of the knife.
  • This design favors the torsional strength of the knife blades on the shaft, although an unintentional displacement of the individual blades relative to one another is already prevented by the combination of the components acting on the blades, namely the drive shaft and the ring.
  • the multi-part nature of the knife with respect to the individual blades has the advantage that, in the event of damage, individual blades can be replaced without having to replace the knife as a whole.
  • the knife 1 consists of two one-piece wings 2 which rotate about an axis 3 in the direction of the arrow 4, each knife wing 2 being provided with an arcuate cutting edge 5. Ends 6 of the wings 2 are connected via a ring 7 arranged concentrically to the axis 3 by means of bolts 8. In the connection area of the wings 2 on the ring 7, additional mass segments 9 are attached to the ring in order to increase the mass moment of inertia of the knife 1 as a whole.
