Definitions

  • the invention relates to a device for dividing cuboid blocks of frozen food or feed into smaller cuboid units (plates), consisting of a circular saw formed by a plurality of blades seated side by side on a drive shaft, over a main conveyor track for the blocks formed by a plate and is arranged at a smaller distance from it than the height of the blocks, from separating elements aligned with the blades of the circular saw for separating the webs in the blocks not separated from the blades of the circular saw, and from a collecting and application unit assigned to the circular saw the material machined by the circular saw can be applied to the smaller units.
  • plates consisting of a circular saw formed by a plurality of blades seated side by side on a drive shaft, over a main conveyor track for the blocks formed by a plate and is arranged at a smaller distance from it than the height of the blocks, from separating elements aligned with the blades of the circular saw for separating the webs in the blocks not separated from the blades of the circular saw,
  • a device for dividing cuboid blocks which works with a band saw.
  • One difficulty with the use of band saws is the high cutting loss.
  • the machined material can not be, as in the known device described with of the circular saw and reapply.
  • Another disadvantage is that the cuts can be made less accurately with a band saw than with a stiff circular saw blade. If there are hard spots in the frozen block, there is a risk that the saw band will move sideways. As a result, the tolerance is exceeded in the subsequent division upwards and downwards, so that the desired exact dimensions required for the exact weight are not achieved with the smaller units, but also the smaller units with the exact ones Dimensioned guides get stuck.
  • the invention has for its object to provide a device of the type mentioned, with which there is even less loss of cut when dividing blocks into smaller units (plates).
  • the separating elements are designed as blades of a further circular saw arranged below the plate of the main conveyor track, which reach through the plate of the main conveyor track to such an extent that the webs are at least largely severed that further below the plate of the main conveyor track
  • Secondary conveyor track is arranged with the opposite direction to the conveying direction of the main conveyor track and that between the end of the secondary conveyor track and
  • a transfer unit is provided at the beginning of the main conveyor track, with which the incoming blocks can be transferred from the secondary conveyor track to the main conveyor track.
  • a transverse conveyor track with the conveying direction of the first conveyor track transversely extending conveying direction is provided, a cut-to-length unit being arranged at the transition from the secondary conveyor track to the first conveyor track, with which the frozen food or feed supplied as a rectangular strand can be divided into the individual blocks.
  • the end faces of the "raw blocks” can no longer be processed.
  • the freezing of the "raw blocks” on the end faces can be done either by the natural cold of the "raw blocks” or in a continuous freezer, preferably in the joint at the abutting end faces of the "raw blocks” a liquid or pasty mass from the Material of the blocks is fed.
  • the freezing together of the "raw blocks” and the cutting of the "raw blocks” to the correct length for the circular saw can also be achieved independently of the two-lane transport of the blocks one above the other.
  • Frozen raw blocks with a rectangular cross-section are pushed in the longitudinal direction via a lower transverse conveyor track 2 onto a lower secondary conveyor track 3. Via the lower transverse conveyor track 3, they are conveyed in the transverse position to a transfer unit 4 arranged at the end of the transverse conveyor track 3.
  • the transfer unit 4 consists of a further lower transverse conveyor track 5, a lifting table 6 and an upper opposite transverse conveyor track 7, which leads to an upper main conveyor track 8.
  • the transport directions on the individual conveyor tracks are indicated by the arrows T1, T2, T3, T4, T5.
  • the conveyor tracks 1,3,5,7,8 can be formed by grates or plates. Guide rails are used for lateral guidance of the parts to be conveyed 1a, 1b, 3a, 3b, 5b, 7a, 7b, 8a, 8b, 8c are provided.
  • the transfer unit 4 consists of a lifting table 9 which can be raised from the level of the lower cross conveyor track 5 to the level of the upper cross conveyor track 7.
  • the movement of the lifting table 9 is indicated by the double arrow T6.
  • a continuous freezing chamber 10 is arranged on the upper transverse conveyor track 7.
  • a saw 11 is provided which can be moved in the direction of arrow T7. This saw 11 is used to cut the blocks to be cut.
  • a circular saw 12 is arranged above the plate of the conveyor track 7, the circular saw blades 12a to 12d of which are arranged on a common drive shaft at a distance from one another and at a distance from the top of the plate of the conveyor track 8 which is smaller than the height of the cut blocks which have been cut to length 13.
  • the circular saw 12 is assigned a collecting and application unit, which consists of a hood 14 enclosing the circular saw 12 and a pressure roller 15 which applies the machined material uniformly to the tops of the blocks.
  • a further circular saw 16 is provided below the plate of the main conveyor track 8 and in the conveying direction T5 of the circular saw 12, the saw blades of which extend through the plate of the conveyor track 8 so far that the webs which are not severed when severed by the circular saw 12 are completely or at least almost severed will.
  • Carriers 17, 18, 19, 20 serve to promote blocks 1, 13.
  • the ingots 1 are pushed in the longitudinal direction and face-to-face on the secondary conveyor track 3, by means of which they are pushed forward to the transfer unit 4 in the transverse position and also adjacent to one another.
  • the blocks 1 are again pushed in the longitudinal direction onto a secondary conveyor track 5 by means of drivers 18 to the lifting table 9.
  • the lifting table 9 brings the blocks to the level of the upper cross conveyor 7, where they are pushed through the continuous freezing unit 10 by carriers 19. Before they get into this continuous freezing unit 10, a liquid or pasty mass made of the material of the blocks is introduced between the end faces. The blocks then freeze together at the parting line 21 in the freezer unit 10.
  • the blocks are then advanced to the guide bar 8b, which forms a stop, and cut to the desired length by the saw 11 in this position. From here, the blocks 13 are advanced again in the transverse position to the two circular saws 12, 16, where they are divided into individual plates.
  • the machined material produced by the upper circular saw is collected by the hood 14 and applied again by the roller 15.
  • the material machined by the lower circular saw 16 is applied to the upper sides of the blocks 1 conveyed on the lower secondary conveyor track 3.
  • the overall cutting loss is extremely low, since machined material that is produced on the circular saws 12, 16 is reapplied and the end faces of the plates to be cut into smaller units are geometrically cut in front of the circular saws 12, 16 by cutting to length the frozen food supplied as a strand have been designed precisely, without resulting in non-recyclable panes.
