Definitions

  • the invention relates to a machine for cutting a strand of material into slices with a cutting device which has a circular knife rotating on a rotatable drive arm, a feed device for the strand of material to be cut and a receiving device for the cut slices, which has at least one contact surface on which the cut off Disks are movable away from the cutting device.
  • Such a machine is known for example from DE 37 06 485 C2.
  • This machine which is also provided for dividing the estate strand, is designed as a table or counter device.
  • the cutting device is arranged in a housing below the transport cross section of the material strand.
  • the rotating circular knife is attached to a drive arm, which is rotatable about an axis parallel to the feed direction.
  • the drive arm is actuated by a crank mechanism and therefore carries out an oscillating pivoting movement.
  • the drive arm carrying the circular knife is wedge-shaped.
  • the drive arm In connection with the wedge shape of the knife in cross-section in its edge area, the drive arm is designed such that a tangent to the end of the housing runs approximately through the cutting edge of the knife.
  • the invention has for its object to develop such a machine so that damage to the material to be cut is excluded even if it is very sensitive to deformation or pressure forces.
  • this object is achieved according to the invention in that the contact surface forms an angle with the feed direction of the crop strand such that a wedge-shaped gap is formed for the drive arm of the cutting device between the cut disks and the cut surface of the crop strand.
  • the creation of the wedge-shaped gap ensures that the last disks which have already been cut off are not entrained by the drive arm due to frictional forces when the drive arm is moved away from the contact surface, as a result of which the desired loaf-like disk arrangement would be disturbed.
  • the axis of rotation of the drive arm is arranged not far from a vertical central plane of the loaf of bread, so that the drive arm is within the conveying cross section makes both a downward and an upward movement with respect to the contact surface of the disks.
  • the compressive forces acting on the disc being created during the cutting process are particularly low if a housing of the drive arm is wedge-shaped in a longitudinal section running parallel to the feed direction, since in this case the knife with the drive arm and the cut-off disc are very good at the wedge-shaped gap are adapted between the cut surface of the crop strand and the existing disk pack.
  • Best cutting results can be achieved if the angle between the contact surface and the feed direction is between 5 ° and 15 °, preferably 10 °.
  • a step falling in the feed direction is provided at the transition from a contact surface of the feed device to the contact surface of the receiving device for the cut-off slices. Due to this step, a nascent disk can be prevented from penetrating into a gap between the knife and a shaft bottom forming the contact surface of the discharge device in the last phase of the cutting process, whereby particularly sensitive material to be cut can be damaged.
  • the contact surface of the feed device extends with its end face parallel to the knife plane so far in the feed direction that an upper edge of the end face forms a counter-cutting edge to the end edge of the cutting knife, no tearing or breaking of the material to be cut occurs even in the final phase of the cutting process.
  • the axis of rotation of the drive arm is arranged above the conveying cross section of the crop strand.
  • the contact surface of the feed device can be approximated to the knife level so that the upper edge of the end face of the contact surface and the cutting edge of the circular knife, such as cutting edge and counter cutting edge, interact as described above, as a result of which a very good cutting result can be achieved .
  • the machine 1 shown in FIGS. 1 and 2 is used to cut a loaf of bread 2, indicated by dashed lines, into slices 3, of which only the last, just cut slice 3 is shown in FIG. 1 for the sake of simplicity.
  • the machine 1 has a feed device 4, which is designed in the form of a shaft formed from sheet metal.
  • the loaf of bread 2 to be sliced lies with its underside on the top of a shaft bottom 5 and is thereby advanced in the direction of advance (arrow 6) with a known feed device (not shown in the figures) onto a cutting device 7 described in more detail later.
  • the shaft in the area of the feed device 4 (but also in the area of a receiving device 8 for the cut-off slices 3 that follows behind the cutting device 7) is arranged with its base 5 inclined by approximately 45 ° to the horizontal.
  • the loaf of bread 3 is therefore not only supported on the shaft floor 5, but also with a lateral surface on a shaft wall 9 arranged at right angles thereto.
  • the cutting device 7 consists of a rotary-driven circular knife 10, which is mounted in a drive arm 11, which is also driven by rotation.
  • the circular knife 10 is driven by means of a belt drive, which is closed within a housing 12 of the drive arm 11 and is therefore protected from bread crumbs and flour dust.
  • the drive arm 11 rotates about its axis of rotation 13 in the clockwise direction (arrow 14), whereas the circular knife 10 rotates counterclockwise about its axis of rotation 15 (arrow 16).
  • the drive arm 11 rotates uniformly with the circular knife 10, the latter penetrates - as can be seen in FIG. 1 - into a gap between the feed device 4 and the receiving device 8.
  • the circular knife 10 sweeps with its cutting edge 17 so close to an edge 18 of an end face of the shaft bottom 5 that there is a very important interaction of the cutting edge and the counter cutting edge for the cutting process.
  • the circular knife 10 is curved so that the slices being created, starting from the cutting edge 17, are deflected by the side surface of the circular knife 10 facing the slices 3.
  • the housing 12 of the drive arm 11 is wedge-shaped in longitudinal section in its end region facing away from the axis of rotation 13 of the drive arm 11 and therefore finds sufficient space in the wedge-shaped gap which is between the one just cut off Disk 3 and the disk pack (not shown) located in front of it are present due to the inclination of the contact surface 19 of the shaft bottom 20 of the receiving device 8.
  • the angle ⁇ between the contact surface 19 and the feed direction (arrow 6) or the shaft bottom 5 of the feed device 4 is 10 °.
  • An angle ⁇ with which a housing end section of the drive arm 11 is inclined with respect to the plane of the circular knife 10 is also of this order of magnitude.
  • the angular velocity of the circular knife 10 is approximately ten times greater than the angular velocity of the drive arm 11, as a result of which very good cutting quality can be achieved.
  • the rotating drive arm 11 with the circular knife 10 is covered by a knife protection box 21, which extends only over a small width and is also partially indicated in FIG. 1.
  • the cross section of the machine 1 is essentially pentagonal, the shafts of the feed device 4 and the receiving device 8 being accessible from a beveled side 22.
  • a particularly compact construction results, while at the same time the advantages of a simple and secure support of the loaf of bread 2 on the shaft bottom 5 and the shaft wall 9 are given .
  • the cut slices 3 are secured against falling over by a support device, so that a slice packet in the form of the original loaf of bread 2 is gradually built up.
  • the support device is pushed in synchronism with the bread loaf 2 due to the advancing movement of the loaf of bread 2 and thus also the advancing movement of the slice packet from the first slice 3 lying against it, so that when all slices 3 are cut off a support in the form of the previously cut slice 3 is always present .
