Definitions

  • the invention relates to a cutting device for portioning chunks of foodstuffs and foodstuffs, in particular cheese, with a knife blade which is held displaceably transversely to the feed direction of the piece to be cut and which has a grinding surface on at least one side of its insert edge.
  • this part of the cheese block should be as small as possible, since this is practically a waste product.
  • the risk of the knife blade evading is particularly great.
  • the knife blade leading over a certain length deviates laterally by up to 12 mm when cutting cheese, in particular when cutting off the beginning and end section, so that no straight cut and no optimal weight portioning of the next or the preceding one Section can be achieved. It can also happen that the knife blade does not penetrate the cheese block at all if a too small gate is to be cut off, so that the knife blade immediately dodges to the side without penetrating into the cheese block.
  • the present invention has therefore set itself the task of creating a cutting device for portioning lumpy foods and foods, especially cheese, with which the disadvantages shown can be avoided and with which exact portioning is made possible by exact cutting.
  • the knife blade for parallel or acute-angled alignment of the knife blade with respect to the feed plane of the carrier and thus with respect to the cutting surface of the piece to be cut is held in an angle-adjustable manner on a carrier carrying out the cutting feed movement.
  • the lateral force component which counteracts the knife and is applied by the gating part of a piece of cheese, is very small on this gating side, so that there is no support from this side. As a rule, the knife would therefore deflect and bend in the direction of the gate to be cut. If the knife blade is now inclined accordingly with respect to the feed plane of the carrier which receives the knife blade, compensation can be created so that an exact cutting surface is always achieved in the angle provided for this purpose in relation to the feed direction of the piece to be cut.
  • a particularly advantageous effect is one in which the angle between the feed plane and the blade is continuously variable and possibly the knife blade can be fixed in the set position relative to the carrier. As a result, an exact angle setting can always be made depending on the requirement and the type of the piece to be cut.
  • the inclination of the knife blade with respect to the feed plane of the carrier during the cutting process can be adjusted as a function of the lateral forces acting on the cutting area of the knife blade. It would thus be possible to produce an approximately angular adjustment of the knife blade by mechanical, pneumatic, hydraulic or electrical means, in which case the knife blade can then be adjusted slightly automatically during a cutting process with reference to the force components acting on it.
  • a particularly simple construction results when the knife blade is held about a carrier which can be pivoted about an axis which runs transversely to the feed direction and lies in the cutting edge of the knife blade.
  • the cutting plane based on the direction of advance of the carrier, is constant with each angle setting, so that there are no problems with regard to the advance of the piece to be cut even when changing the angle setting of the knife blade.
  • the knife blade be assigned adjustable and lockable end stops to limit the angle adjustment.
  • the area in which the knife blade is to be adjusted for cutting foodstuffs and foodstuffs can thereby be limited.
  • the adjustment angle of the knife blade corresponds at least approximately to the angle of the abutment surfaces, based on the central plane of the knife blade.
  • holders for a knife blade are provided on the carrier in various predetermined angular positions relative to the feed plane.
  • FIG. 1 shows schematically a cutting device; Figures 2 to 4 different situations with different angular positions of the knife blade with respect to the feed plane.
  • FIG. 5 shows an enlarged knife blade inserted into a piece to be cut with the force relationships shown;
  • Fig. 6 is the same representation as in Fig. 5, but with the knife blade at a certain angle to the feed plane.
  • a support table 1 is shown, on which a piece 2 to be cut is fed, and a carrier 4, which is held displaceably in the arrow directions 3 and on which a knife blade 5 is held.
  • a conveyor belt 6 is provided as a support table in the embodiment shown, which, depending on the size of the desired portions, advances the piece 2 to be cut by a certain amount after each cut to be made.
  • the exact design of this support table is not shown, since this is not the subject of the present invention. In any case, a number of support rollers or support plates would have to be provided here, so that a proper feed and a firm support for the piece 2 to be cut is given.
  • the design of the support table is also conceivable in other ways, e.g. as a flat table top or with rollers for supporting the piece 2 to be cut, in which case a corresponding slide could be provided for the feed.
  • the carrier 4 per se performs the cutting movement for the knife blade 5 held on this carrier 4 by its movement in the arrow directions 3.
  • the displacement of the carrier 4 can be carried out mechanically, pneumatically, hydraulically and / or electrically, with a cyclical adjustment in each case according to a pre thrust of the piece to be cut 2 is possible by appropriate electrical or electronic circuits.
  • the support table will be aligned in the horizontal direction and the support 4 can be displaced in a plane perpendicular to this support table.
  • the carrier 4 is not aligned exactly at right angles to the support table if, for example, oblique cuts in the piece 2 to be cut are desired. It would also be possible to move the knife blade in the horizontal direction against a support table standing in the vertical direction.
  • the essence of the present invention lies in the fact that the knife blade 5 is held in an angle-adjustable manner on this carrier 4 which carries out the cutting feed movement.
  • the knife blade In the position shown with solid lines, the knife blade is aligned parallel to the feed plane of the carrier 4. In the two positions shown in broken lines, the knife blade in each case forms an acute angle ⁇ with the feed plane of the carrier 4.
  • the gate 7 When cutting a piece 2, the gate 7 must first be cut off, whereupon the individual sections 8 are then cut off in the same or different sizes. In the last cut to be made, a gate 9 is again to be cut off.
  • the lateral force component FG1 which is exerted from the side of the gate 9 against the grinding surface 12, is significantly smaller than the lateral component FG2, which is opposed by the relatively wide piece 2.
  • the knife blade 5 extends about an axis which runs transversely to the feed direction 3 and lies in the cutting edge 10 of the knife blade 5 15 is pivotable. This can be done, for example, by inserting the knife blade 5 in a holder which can be pivoted about this axis 15 on the carrier 4.
  • adjustable and lockable end stops 16 and 17 are provided which limit the angle adjustment of the knife blade. These end stops 16 and 17 can be formed, for example, by adjustable screws 18 and 19. For the cutting process itself, the knife is fixed in the respective angular adjustment and also when the knife blade 5 is aligned parallel to the feed direction 3 sheet in this setting is necessary.
  • the angle between the feed plane of the carrier 4 and the knife blade 5 can be varied continuously, the knife blade 5 possibly being fixable relative to the carrier 4 in the set position.
  • an exact angle adjustment can always be made depending on the requirements and the type of the piece 2 to be cut.
  • the inclination of the knife blade with respect to the feed plane of the carrier 4 before and / or during the cutting process is adjustable depending on the lateral forces acting on the cutting area of the knife blade 5. It would thus be possible to produce an approximately angular setting of the knife blade by mechanical, pneumatic, hydraulic or electrical means, in which case the knife blade 5 can then be adjusted slightly automatically with reference to the force components acting on it.
  • the adjustment angle ⁇ of the knife blade 5 corresponds to the angle ⁇ of the grinding surfaces 11, 12 corresponds to the central plane 14 of the knife blade 5. Since with such very narrow gates 7 and 9 there is practically no counteraction on the knife blade 5 from this side, it is advantageous if the corresponding grinding surface 11 or 12 corresponds directly to the feed plane.
  • Such a correspondence between the angles ⁇ and ⁇ is of course given only very specifically applicable force components which act on the cutting area of the knife blade 5. It is therefore also possible that the adjustment angle ⁇ of the knife blade 5 is chosen to be smaller or larger than the angle ⁇ of the abutment surfaces 11, 12.
  • the force components which lead to the bending of the knife during the cutting process can thus be reduced or eliminated, so that exactly straight cuts can be carried out without bending the knife.
  • This also ensures with a corresponding curvature of the gates 7 and 9 that when these gates 7 and 9 are cut off, the knife does not simply slide off the surface.
  • the measure according to the invention also makes it possible to cut off the gates 7 and 9 much thinner than was previously possible, so that the gates to be separated and possibly further used in some way also become much smaller in weight.
  • the measures according to the invention can of course also be used if a grinding surface for forming the cutting edge 10 is provided only on one side. It is then again achieved by a corresponding angle adjustment that the lateral force components are balanced so that bending of the knife is prevented during the cutting process.
  • abutment surfaces 11, 12 on both sides these advantageously lie symmetrically with respect to one another in relation to the central plane 14 of the knife blade 5.
  • the two grinding surfaces have unequal ground angles, that is to say the cutting edge is formed by two grinding surfaces which are asymmetrical with respect to one another in relation to the central plane 14 of the knife blade 5. Of course, this again causes a corresponding change in the adjustment angle of the knife blade for the cutting process.
  • a cutting device By designing a cutting device according to the invention, all cut-resistant types of cheese can be cut easily and precisely portioned. All cheese molds must also be portioned with such a cutting device.
  • the cutting device according to the invention can, however, also be used for all other foodstuffs and foodstuffs to be cut into portions, and also for all cutting devices usable in other areas with which similar materials are to be cut in consistency with foodstuffs and foodstuffs.
