Definitions

  • the invention relates to a device for the defined severing of the backbone of an animal body half transported on a conveyor device along a cutting line
  • a cutting unit with at least one machine-driven circular knife including a suspension unit held on a support system, via which the cutting unit is suspended above the conveyor device, with a The upper frame fixed to the support system and with a lower frame fixed to the cutting unit, the frames being connected to one another via a support arm that can be pivoted at least in relation to the upper frame via a first joint bearing with a first joint axis and at least one guide strut pivoted at the end with respect to the frame are connected, further comprising a guide unit held on the lower frame as a part of the cutting mechanism with two opposite insertion sides facing one of the carcass half and widened in front of the Guide elements held m circular knives, over which the device is guided on the backbone during separation.
  • the part of a spinal column located above the base of the ribs or the backbone of an animal body half is separated lengthwise in order to be able to further process the surrounding meat of a middle section of the animal body half.
  • the cut made here to separate the spine from the center piece is referred to below as the CB cut.
  • the carcass halves can come from all large animals, in particular a middle pork half (in English “Middle”) or a chop string (in English "Loin”).
  • it is important to make the CB cut as precisely as possible along the naturally curved course of the backbone referred to as the cutting line in the present application.
  • the CB cut can be performed with a conventional band saw.
  • this requires the operator to guide the half of the carcass on the band saw, and this entails an extremely high risk of accidents.
  • a device of the generic type developed by the applicant is disclosed in the German utility model DE 20 2015 104 624 U1.
  • two machine-driven circular knives are arranged opposite one another with an offset and at a cutting angle, so that they separate the backbone in a V-shaped cut from two sides from the middle piece of the carcass half.
  • the guide elements of the guide unit of the cutting mechanism are designed as tubular guide bars cranked towards the insertion side, with one of the two circular knives being supported by a guide bar
  • the device is passed through.
  • the device is held above a conveyor belt by a suspension unit so that the circular knives grip under the spine when it is cut.
  • the device is also guided horizontally on the backbone via the guide bars. Nevertheless, it is the case here that the device wobbles due to its inertia and cannot automatically and precisely follow the naturally curved contour of the backbone in the vertical direction, so that the device must be guided by hand or through an additional device for a precise cut.
  • the object of the present invention is to provide an alternative, inexpensive and compact device of the generic type with which the CB cut can be carried out fully automatically and aligned with the spine to be separated.
  • the invention in connection with the preamble of claim 1 is characterized in that the circular knife is held along the cutting line when it is cut off by adding a mass to the support arm on a side opposite the cutting mechanism relative to the first joint axis of the first joint bearing a mass center of gravity is placed in such a way that a first torque acting on the first joint axis as a result of a weight force of the cutting unit has a second torque acting on the first joint axis as a result of a counterbalance weight force of the mass body is opposite, the second torque being greater than 30% and less than 100% of the first torque.
  • the particular advantage of the invention consists in the balanced suspension of the cutting unit by the suspension unit. This ensures that the cutting unit is suspended with an essentially balanced mass inertia.
  • the circular knife can automatically be aligned with the backbone when the backbone is separated from the center piece of the half-carcass, in that the half-carcass transported on the conveyor is pressed against the essentially balanced weight of the cutting mechanism. The circular knife is thus held at the level of the cutting line when it is cut off. This makes use of the fact that a cutting resistance when cutting through a meat or muscle fiber mass, which is found essentially below the spine to be separated in the middle piece, is lower than when cutting through a bone or cartilage mass, which has the backbone.
  • the device When cutting, the device is suspended at a cutting height above the conveyor device, which is selected so that the circular knife can reach under the spine at the beginning.
  • the device is swiveled out of a balanced starting position and, due to the inertia, the circular knife is pressed in the direction back to the starting position with a slight pressure against the backbone.
  • the weight of the cutting mechanism is balanced in such a way that the cutting resistance of the bone mass of the backbone is sufficiently great that the circular knife finds itself in the underlying meat or muscle fiber mass or below the
  • Bone attachment of the spine is held.
  • the center of gravity of the mass body relative to the first spherical bearing is placed so that the second torque is greater than 50% and less than 80% of the first torque.
  • This arrangement ensures that a counterweight to the cutting unit formed by the mass body compensates for a large part of the weight of the cutting unit and presses a small part of the weight of the cutting unit in the form of a slight pressure force on the backbone of the carcass half to be cut. In this way, the device is guided on the backbone in the vertical direction during separation.
  • the cutting line when cutting, the cutting unit is also suspended in a defined manner via the suspension unit with several degrees of mechanical freedom.
  • the support arm absorbs the weight of the cutting unit, the guide strut takes over the alignment of the cutting unit within the suspension unit.
  • the support arm is pivotably connected to the lower frame via a second joint bearing with a second joint axis.
  • the cutting mechanism held on the lower frame can be pivoted with respect to a longitudinal axis of the support arm.
  • the suspension unit prevents the cutting unit from sagging and essentially holds the cutting unit in a horizontal plane when it is cut.
  • the support arm is connected to the upper frame via a third joint bearing positioned above the first joint bearing with a vertically oriented third joint axis.
  • the first joint axis of the first joint bearing and the second joint axis of the second joint bearing are oriented horizontally.
  • the support arm is preferably designed such that more than one mass body can be held on the same and that mass bodies of different masses can be held on the support arm in an exchangeable or expandable manner. In this way, the weight of the cutting unit can be balanced in a flexible ratio.
  • the first joint axis is the first
  • Joint bearing or the second joint axis of the second joint bearing mounted horizontally or vertically inclinable.
  • the support arm is mounted displaceably along the first joint axis or along the second joint axis.
  • the suspension unit has several mechanical degrees of freedom and ensures that the cutting unit is suspended both in the horizontal direction and in the vertical direction so that it can move or is displaceable with respect to the joint axes of rotation and is suspended so that it can pivot about the joint axes of rotation of the joint bearings. In this way, the circular knife can flexibly follow the cutting line when cutting.
  • the guide elements are designed as plow-shaped guide plates. They enclose the backbone in a V-shape when severed. The guide elements are widened towards the introduction side and form a type of introduction funnel or introduction lane, over which the
  • the guide elements enclose the backbone during separation and ensure that the device is guided or aligned on the backbone in the horizontal direction. In this way, one is on the guide elements and the rotating circular knife when cutting
  • Three-point fixing of the device is formed on the half of the carcass, which ensures that the circular knife penetrates into the half of the carcass driven forward on the conveyor device and makes the CB cut.
  • Another shape of the guide unit with, for example, runner-shaped guide elements which are cranked towards the insertion side, is also conceivable.

  • the second guide element and the fork swivel joints can thus be designed to be compact and inexpensive, since the essential forces as a result of the animal body half being advanced by the conveyor device are absorbed by the first guide element.
  • the suspension unit has two guide struts of equal length.
  • the pivot axes of the pivot bearings are oriented horizontally and the guide struts are held parallel to the support arm and lie opposite one another in parallel and at the same height.
  • the support arm and the guide struts of the suspension unit form a flexibly movable parallelogram arrangement, which holds the cutting mechanism essentially horizontally, but very movably above the conveyor device with the mechanical degrees of freedom described above.
