Definitions

  • the invention relates to a device for cutting fruit, vegetables or the like into slices, with a knife holding plate, on the front edge of which a V-shaped cutting knife is arranged, which consists of two knife blades; two frame strips arranged essentially in parallel, which are connected to one another by the knife holding plate and at least one further crosspiece; and a slide plate guided on the frame strips and insertable parallel to the knife holding plate, a narrow gap remaining between the rear edge of the slide plate and the cutting knife.
  • Such a device is known for example from EP 0 306 017 A2, although the V-shaped cutting knife used there is formed in one piece, which is particularly disadvantageous in terms of production technology.
  • FIG. 1 schematically showing a device according to the preamble of claim 1, as has been used by the Amelder for some time is distributed.
  • FIG. 2 shows an enlarged representation of the corresponding arrangement of the knife blades in the device according to FIG. 1.
  • the known device 1 comprises two frame strips 2, which are held together in their rear part by a knife holding plate 4 and in their front part by two transverse webs arranged on the underside of the device 1 and not shown in the drawing.
  • a parallel to the knife holding plate 4 insertable slide plate 8 is arranged, which is guided in a lateral groove in the frame strips 2 and is arranged in the engaged state so that between the rear portion of the slide plate 8 and a cutting knife 6, the is attached to the front edge of the knife holding plate 4, a narrow gap remains.
  • the slide plate 8 on which the material to be cut is additionally provided with longitudinal grooves 9 provided for this purpose.
  • the 2 shows the arrangement of knife blades 10 and 12 of the cutting knife 6 of the known device 1 in an enlarged view.
  • the dashed lines each indicate a profile step 16 of the knife blades 10 and 12, the areas of the knife blades 10 and 12 lying towards cutting edges 11 and 13 being higher than the areas adjacent to the peripheral edges 14 and 15.
  • the profile stages 16 usually consist of bevels, the areas of the knife blades connected by these bevels running parallel to one another.
  • a V-tip 19 of the cutting knife 6 is formed by the two knife blades 12 and 13 abutting one another, their mounting in the knife holding plate 4 being carried out by rivet-like, corresponding bores 17 of the two knife blades 10 and 12 penetrating plastic knobs.
  • the plastic knobs are manufactured by injection molding.
  • the known device is disadvantageous in that it is very difficult to keep the two knife blades exactly on a cutting plane, so that when certain cutting forces, e.g. B. when cutting relatively hard objects, picking up the knife blades is inevitable. A corresponding displacement of the two knife blades against each other then increases more and more over time and ultimately leads to the entire device becoming unusable.
  • the present invention is therefore based on the object of developing the known device to ensure that the knife blades are held reliably in order to improve the overall functionality and service life of the device.
  • this object is achieved in that the peripheral edge of the knife blades is held in a form-fitting manner by injection-molded plastic strands in the form of a lying U-profile, at least in its rear area adjacent to the V-tip of the cutting knife.
  • This configuration of the mounting of the knife blades in the knife holding plate makes it possible to reliably avoid the lifting of the blades, which has hitherto been inevitable in the long run, and the resulting defects in the common cutting plane.
  • the molded plastic strands completely merge into the plastic mass of the knife holding plate and at the same time penetrate the rear region of the knife blades at at least one point. It is particularly preferred that either at least one separate hole is provided in the rear area of each knife blade or one edge cutout each, the edge cutouts having the shape of a single elongated hole together after the knife blades have been assembled to form the cutting knife.
  • the plastic strands thus prevent the U-profile from expanding and thus loosening the positive locking, but also ensure that the knife blades are precisely secured against displacement in the plane of the cutting surface.
  • a further embodiment of the invention proposes that the knife blades are arranged in such a way that at least one attachment of one knife blade lies at least partially below the other knife blade, said attachment being kinked, beveled, designed as a step or similar in relation to the main part of the one knife blade is formed.
  • This measure according to the invention additionally effectively counteracts a widening of the knife blades in the area of the knife tip, whereby the corresponding kinking, step formation or beveling of the knife blade located below ensures that the cutting surfaces of the knife blades actually lie exactly in one plane and also remain there reliably.
  • the invention further provides that the knife blades have a profile with a step which is rounded in the rear area of the knife blades adjacent to the tip of the knife so that an almost semicircular profile guidance results when the knife blades are assembled.
  • This special design of the rear area of the knife blades makes it particularly firm due to the molded plastic strands in the particularly sensitive area of the V-tip of the cutting knife, since the entire circumferential edge can be encompassed in a form-fitting manner.
  • a generic device is thus made available, the knife blades of which are held particularly securely and firmly in the knife holding plate and which ensures that the cutting surfaces of the knife blades remain reliably in one plane, even under high mechanical and thermal loads.
  • the injection molding techniques used according to the invention are particularly easy to use, since no core pull is necessary for demolding.
  • FIG. 3 shows a representation similar to FIG. 1.
  • An essential difference between the device according to the invention according to FIG. 3 and the device according to the prior art according to FIG. 1 lies in the different guidance of the step profile, which is indicated by the dashed lines in both drawings Lines on the knife blades is indicated.
  • these profile steps run straight from one end of the knives blade to another.
  • the respective profile ends at a front side edge of the knife blade in front of the frame strip 2, while at the other end it ends in a curve, so that when the knife blades are assembled, an almost semicircular runout of the step profile at the upper end of the V-shaped knife 6 results.
  • the form-fitting holding of the knife blades 10 and 12 of the cutting knife 6 takes place in the specified manner at least in the area of the V-tip 19 of the cutting knife 6.
  • an extension 18 of the left-hand knife blade 12 is provided, which bends towards the main part of the knife blade 12 , beveled or designed as a step so that it comes to rest under the section of the right knife blade 10 located there.
  • at least two bores 17 are provided, one of which is arranged in one of the two knife blades 10 and 12.
  • the molded plastic strands overlap at least this area of the knife sound form-fitting from both sides and reach through the holes 17 at the same time.
  • edge cutouts 21, 22 can alternatively also be provided in each knife blade 10, 12, which together take the form of a single elongated bore, which can then be penetrated by the plastic carriers.
