Definitions

  • the invention relates to knives, in particular rotating knives, in particular rotating sickle knives, as used primarily in slicers for slicing sausage, cheese or other strand-shaped, elastic food products.
  • the problem here is that the thin and very elastic disks temporarily stick to the back of the knife facing the disk when they are cut off and therefore do not lie flat when separated and thrown onto a base, but instead form waves or folds or are not in the desired target position. Come to rest on the surface.
  • the DE-10 2026 005443 A1 discloses a knife according to the preamble of claim 1.
  • a cutting device such as a slicer, which cuts strand-shaped elastic products such as sausage or cheese, so-called calibers, into slices at high speed, usually has a base frame to which, on the one hand, a product holder is attached, on which the product to be sliced or the product strand is fed to the cutting point and on the other hand a rotating knife, which successively separates slices from the strand at the cutting point.
  • the knife especially in the slicers used today, is usually a rotating knife, usually a so-called sickle knife, which, in contrast to a sickle, does not carry the cutting edge on the concave inner contour but on the convex outer contour, which due to the direction of rotation of the sickle knife Front edge of the knife base body is.
  • the cutting edge points in a direction of progression of this cutting edge, the so-called cutting direction a constantly increasing, in particular continuously increasing, distance from the axis of rotation, which can also have the shape of a geometric spiral around the axis of rotation of the sickle knife.
  • the knife is circular disc-shaped with an annularly closed, in particular circularly closed, endless cutting edge on the outer circumference, the axis of rotation of the knife must be moved in the cutting operation in order to cut off slices, in particular oscillating back and forth.
  • the known knives are plate-shaped and have a cross section that is curved outwards on one side, the back of the knife, from the cutting plane defined by the cutting edge, while the knife on the front of the knife - which is in the cutting device of the product holder, i.e. facing the strand of the product lying on it - usually does not protrude beyond the cutting plane.
  • the cutting edge is formed in cross section through the base body of the knife by a front cutting surface, which can be flat, for example, but, e.g. set back radially from the cutting edge, can also have a front recess, and a rear cutting surface, the two cutting surfaces being in run to each other at an acute cutting angle.
  • a front cutting surface which can be flat, for example, but, e.g. set back radially from the cutting edge, can also have a front recess, and a rear cutting surface, the two cutting surfaces being in run to each other at an acute cutting angle.
  • the inner end of the cutting surface facing away from the cutting edge is adjoined by a pressure surface, which is also part of the curved back of the knife, but extends to the cutting plane at a pressure angle that is smaller than the cutting angle.
  • the inner end of the pressure surface facing away from the cutting edge is adjoined by the mostly flat remaining knife back of the plate-shaped knife, which generally has a uniform thickness in this central area, apart from the front recess that may be present on the front of the knife.
  • At least one recess is arranged in the curved back of the knife in order to minimize the adhesion of the disc in separation to the back of the knife, in particular its pressure surface.
  • This at least one recess is adapted to the properties of the product and can also depend on various parameters of the cutting device in which this knife is used, for example the material and the roughness of the outer sides of the knife, the cutting speed and other parameters.
  • One possibility of adapting to such parameters is to vary the size and/or the shape of the cross-sectional area of the recess lying transversely, in particular perpendicular, to the cutting plane and/or transversely, in particular perpendicularly, to the direction of the cutting edge in the direction of the cutting edge, in particular at a sickle-shaped knife.
  • Another possibility is to vary the position, in particular the radial distance, of the recess from the cutting edge in the direction of the cutting edge.
  • the width of the cutting surface - depending on the state of wear - is only around 0.5 mm to 2 mm, while the pressure surface in this direction is at least 10 times, possibly even at least 15 times as wide.
  • the cutting angle is on the order of 30°, while the pressure angle is only around 20°.
  • a parameter to be taken into account is the high speed of such knives in so-called slicers, which is at least 500 revolutions per minute, which is a very significant penetration speed of the cutting edge for a sickle-shaped knife with a maximum radius of, for example, 50cm into the product.
  • the at least one recess is a groove, which extends with its main direction of extension, i.e. primarily, along the direction of the cutting edge, but preferably at a distance therefrom.
  • the bottom of the groove has a uniform curvature transverse to its main extent, so that the groove can be created in a simple manner by grinding with a round grinding wheel.
  • the at least one recess in the top view of this recess is usually located in the printing area and in particular only in the printing area.
  • the recess extends in the direction of the cutting edge, preferably at most up to the transition of the pressure surface into the cutting surface, i.e. the rear cutting surface, which is formed on the back of the knife. This means that the recess does not change due to regrinding of the cutting surface, especially if when the knife is new there is a distance between the cutting surface and the recess of at least 1 mm, better at least 2 mm.
  • the at least one recess in particular in the embodiment as a groove, can also extend only along part of the extent of the cutting edge parallel to the latter, with a finite cutting edge preferably having no recess in the initial region and end region along the extent of the cutting edge is.
  • the size in particular the width measured transversely to the direction of extension of the cutting edge, and/or the shape viewed in the top view of the cutting plane and/or the cross-sectional shape and/or the radial position of the recess relative to the axis of rotation in the direction of extension of the cutting edge can be constant, in particular for circular disc-shaped knives.
  • these parameters can change along the direction of the cutting edge, in particular increase or decrease consistently along the direction of progression.
  • the depressions will preferably be designed differently, with design parameters of the depressions preferably increasing or decreasing continuously in a direction along the direction of the cutting edge.
  • the changing entry angle of the cutting edge into the product as well as the changing cutting speed i.e. the relative speed between the knife and the product at a point on the cutting edge, can be taken into account - especially with a knife that is not in the shape of a circular disk in the product must be taken into account.
  • the thickness of the base body of the knife is a maximum of 15 mm, better a maximum of 12 mm, better a maximum of 8 mm.
  • the maximum depth of the depression should be at most 2 mm, better at most 1 mm, better at most 0.5 mm, better at most 0.3 mm.
  • the depth of the depression should be a maximum of 20%, better a maximum of 10%, better a maximum of 5%.
  • the clearance angle with which, in a cross section through the recess, the flank facing the cutting edge runs to the back of the knife immediately adjacent to the edge of the recess can - especially in the case of circular disc-shaped knives - be constant along the direction of the cutting edge for a single recess or for each Recess, and in the case of several recesses, also be the same across the number of recesses.
  • this value can increase or decrease steadily along the direction of the cutting edge, preferably continuously.
  • the at least one recess When viewed from above the pressure surface, the at least one recess should extend over at least part of its extent to the cutting surface in order to avoid a pressure surface running continuously along the cutting surface in the direction of the cutting edge, which promotes the start of adhesion of the disc.
  • the width of the depression measured perpendicular to the cutting edge along the back of the knife should be at least 30%, better at least 50%, better at least 70% of the width of the printing surface in this direction in order to achieve a sufficient effect.
  • the desired effect in the inventive design of the recesses in the back of the knife occurs to a sufficient extent, preferably when the speed of the cutting blade is at least 500 rpm, better at least 700 rpm, better at least 1000 rpm, better at least 1200 rpm.
  • an upper limit of a maximum of 5000 rpm, preferably a maximum of 3000 rpm, preferably a maximum of 2500 rpm, of the cutting blade should not be exceeded.
  • Figure 1a shows a conventional slicer 20 as a cutting device for slicing a strand-shaped product P into slices S.
  • the strand-shaped product P lies on a product support 22, which is usually inclined downwards towards the knife 1, for example a sliding surface or a roller conveyor, and is moved from the rear end by a slide 24 located there, usually step by step. pushed forward, but also prevented from sliding forward too quickly by means of retaining claws 25.
  • the protrusion of the caliber P protruding from the cutting frame 23 is cut off immediately in front of the cutting-side end face of the cutting frame 23 facing away from the slide 24 by a rotating, sickle-shaped knife 1 along a cutting plane 1" as a disk S with a thickness D and usually falls onto one conveyor, not shown.
  • the base body 1b of the plate-shaped knife 1 tapers along its outer circumference in cross section, the acute-angled cutting edge 1a being formed by the rear cutting surface 2 present on the back of the knife 1.2 and the front cutting surface 3 present on the front of the knife 1.1 becomes.
  • the cutting edge 1a running around in a plane defines a cutting plane 1".
  • the rear cutting surface 2 is inclined to the cutting plane 1" at a cutting angle ⁇ . On the side of the rear cutting surface 2 facing away from the cutting edge 1a, it is flatter than the cutting surface 2 Cutting plane 1" at a pressure angle ⁇ to the cutting plane 1" running pressure surface 4, which is intended to push the separated disk S away from the cutting plane 1".
  • Figure 2 shows in an analog representation according to the Figure 1c the design of the knife 1 according to the invention :
  • a recess 5 is arranged in the pressure surface 4, the cross-sectional contour of which - in a section perpendicular to the direction of the cutting edge 1a, the viewing direction of the Figure 2 - represents a circular section, i.e. the bottom of the recess 5 represents part of a circular arc with the center 7, mainly because the recess 5 can then be produced with a round, rotating grinding wheel 8 indicated by dashed lines, the axis of rotation of which is preferably in the direction of view the Figure 2 , i.e. the direction 9 of the cutting edge 1a runs through the in Figure 2
  • the center point 7 of the circular arc of the depression 5 is shown.
  • the depression 5 extends to the transition between the pressure surface 4 and the rear cutting surface 2, but could also be arranged at a distance from this.
  • the depression 5 On the end facing away from the rear cutting surface 2, the depression 5 does not reach the end of the pressure surface 4 there, but its extension in this direction is approximately 60% of the width B measured in this direction the pressure surface 4, but is approximately 10 - 15 times the width b of the rear cutting surface 2 in this direction.
  • the clearance angle ⁇ with which the flanks of the recess 5, in particular the flank pointing in the direction of the cutting edge 1a, open into the surrounding pressure surface 4 is a maximum of 3°, better a maximum of 2°, and the transition can also be rounded. This prevents damage to the cutting surface on product P, especially on disk S.
  • the design of the recess 5 in the top view of the back of the knife 1.2, in particular along the circumferential direction 9 of the knife 1, is in the Figures 3a - c but different:
  • the design Figure 3a is the width BV of the recess 5 measured along the pressure surface 4 and perpendicular to the cutting edge 1a in the circumferential direction 9, and in particular only increases at the beginning and decreases again at the end, with the radially outer edge of the recess 5 even as the width BV increases or decreases always runs at the same distance 12 from the cutting edge 1a, and in particular up to the transition, usually a bend, between the pressure surface 4 and the rear cutting surface 2 or maintains a distance 12 in comparison, as in the upper area of the Figure 3a shown.
  • the recess 5 has an increasing width BV in the cutting direction 9.1, i.e. the circumferential direction as the distance of the cutting edge 1a from the axis of rotation 1 ' increases, in particular a continuously increasing width BV.
  • the recess 5 also extends over the entire circumferential length parallel to the cutting edge 1a, which, however, is not a requirement for a design with a width BV that increases in the circumferential direction.
  • these depressions 5 have, at least in their central region in the circumferential direction 9, a constant width BV measured perpendicular to the cutting edge 1a along the pressure surface 4, which becomes smaller and smaller at the beginning and end and tapers off.
