Definitions

  • the present invention relates to a tool for rotary knives, particularly for cutting food.
  • This type of tool is generally used to remove mold, infiltrations and the like from food such as hams or cheeses, although different applications, for example for cutting plastic products or products that otherwise derive from industrial processes, are not excluded.
  • a tool for rotary knives of a known type is disclosed by EP1418028 .
  • EP1418028 disloses a tool that has a rotating body which can be associated with a tool supporting assembly, on the outer lateral surface of which there is a circular blade obtained monolithically with the rotating body.
  • the rotating body is made to rotate with respect to the tool supporting assembly by way of rotary actuation means, so that the circular blade that is formed thereon can apply a cutting action to the product to be processed, for example a piece of meat.
  • the aim of the present invention is to eliminate the above-mentioned drawbacks of the background art, by devising a tool for rotary knives that allows to remove easily a certain quantity of a product to be processed, such as the unhealthy parts that are present on a piece of meat.
  • an object of the present invention is to provide a tool that penetrates easily in the product to be processed, such as highly seasoned meats which therefore are characterized by high compactness, thus facilitating the operations for removing the unhealthy parts.
  • Another object of the present invention is to provide a tool that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
  • the present tool for rotary knives of the type comprising a supporting element for at least one tool and means for the rotary actuation of the tool with respect to said supporting element, comprising:
  • the reference numeral 1 generally designates a tool for rotary knives of the type that comprises an element P for supporting at least one tool 1 and means, not shown in the figures, for rotary actuation of the tool with respect to the supporting element P.
  • the tool 1 comprises a rotating body 2, which has a rotation axis 3 and can be associated rotatably with the supporting element P about the rotation axis 3; the supporting element P can be gripped by an operator as shown in Figure 3 .
  • the tool 1 comprises at least one pair of cutting elements 4, which are mutually distinct, are jointly associated with the rotating body 2 and form respective cutting profiles 40, which are mutually spaced along the direction identified by the rotation axis 3, so as to form, during the rotation of the rotating body 2, a cutting region that is comprised between the cutting profiles.
  • the rotating body 2 comprises an element 5 for supporting the cutting elements 4 which is substantially circular and sheet-like and is arranged transversely to the rotation axis 3.
  • the supporting element 5 therefore has two mutually opposite faces which are substantially parallel and an outer lateral surface that is substantially circular.
  • the supporting element 5 is annular and therefore also has a substantially circular inner lateral surface.
  • the cutting elements 4 are arranged at the opposite faces of the supporting element 5.
  • the cutting profiles 40 of the cutting elements 4 are arranged so as to be mutually substantially mirror-symmetrical with respect to a central plane of the supporting element 5 that is substantially parallel to its faces and perpendicular to the rotation axis 3.
  • the cutting elements 4 of each pair are arranged at the same face of the supporting element 5.
  • the cutting profiles 40 of the cutting elements 4 are arranged with respect to each other substantially mirror-symmetrically relative to a plane of symmetry that is substantially perpendicular to the rotation axis 3 and is arranged proximate to the face of the supporting element 5 at which the cutting elements 4 are arranged.
  • the cutting profiles 40 protrude at least partially in a radial direction from the profile formed by the outer lateral surface of the supporting element 5.
  • the cutting elements 4 of each pair are arranged in mutual succession along the outer perimetric extension of the supporting element 5, i.e., are not mutually aligned along the direction identified by the rotation axis 3, so as to face each other.
  • each cutting profile 40 has a cut adjustment portion 40a and a removal portion 40b, which are arranged so as to be mutually contiguous; the removal portion 40b is arranged upstream of the corresponding adjustment portion 40a in the direction of rotation 6 of the rotating body 2 that is imparted by the rotary actuation means and is identified in the figures by the arrow 7.
  • the direction of rotation 7 imposed by the rotary actuation means is oriented so that the adjustment portion 40a of each cutting element 4 makes contact with the product to be worked before the corresponding removal portion 40b, so as to define the depth of the cut.
  • each cutting profile 40 forms, at the corresponding adjustment portion 40a, a substantially curvilinear region that is adapted to rest against the product to be worked and forms, at the corresponding removal portion 40b, a region that lies substantially parallel to the rotation axis 3 and protrudes toward the other cutting element 4, so as to remove a given quantity of the product to be processed.
  • the penetration of the removal portion 40b of each cutting element 4 within the product to be cut therefore depends on the dimensions and curvature of the corresponding adjustment portion 40a.
  • the tool 1 comprises a plurality of cutting elements 4, which are associated jointly with the rotating body 2, where each pair of cutting elements 4 has the characteristics described above.
  • the cutting elements 4 are arranged in mutual succession along the outer perimetric extension of the supporting element 5 and are arranged alternately at either face of the supporting element.
  • Each cutting element 4 associated with the supporting element 5 at one of its faces is therefore preceded and followed by another cutting element 4 arranged at the other face of the supporting element.
  • each cutting profile 40 is arranged substantially mirror-symmetrically, with respect to a plane of symmetry that is substantially perpendicular to the rotation axis 3 and is arranged proximate to the face of the supporting element 5 at which the cutting elements 4 are associated, to the cutting profile 40 of the directly preceding and following cutting element 4.
  • the tool 1 further comprises a safety element 8, which is arranged at the outer lateral surface of the supporting element 5 and is shown in broken lines in Figure 3 .
  • the safety element 8 is arranged so as to cover partially the part of the rotating body 2 that is arranged on the opposite side of the supporting element P, so as to prevent the operator from accidentally coming into contact, during use, with the cutting elements 4, leaving exposed only the portion that is designed to cut into the product to be processed.
  • the safety element 8 is associated with suction means, not shown in detail in the figures, which comprise for example a suction duct that is associated with one end of the safety element 8 and is adapted to collect the residues of the product to be processed that have been removed by the action of the cutting elements 4.
  • suction means can be associated with the safety element 8 at the operator's discretion, since they are not provided in the basic embodiment of the tool according to the invention.
  • the rotating body 2 comprises means for mating with the rotary actuation means associated with the supporting element 5.
  • the mating means are formed monolithically with respect to the supporting element 5 and are preferably constituted, in the embodiment shown in the Figures, by a set of teeth 10, which is formed so as to protrude from one of the faces of the supporting element 5.
  • the set of teeth 10 is formed at the outer base of a substantially tubular raised portion 11, which protrudes from one of the faces of the supporting element 5, at its inner lateral surface, and lies substantially coaxially with respect to the supporting element.
  • the teeth of the set of teeth 10 lie substantially parallel to the rotation axis 3 and are designed to mesh with a gear, not visible in the figures, which is inserted within the supporting element P and has a rotation axis that is substantially perpendicular to the rotation axis 3.
  • the present invention does not exclude different embodiments of the mating means, which are known to the person skilled in the art.
  • the tool 1 is associated with the supporting element P so that the set of teeth 10 meshes with the rotary actuation means, which are not visible in the figures.
  • the operator who grips the supporting element P moves the tool 1 toward the product to be processed, for example a piece of meat, and activates the rotary actuation means.
  • the rotating body 2 thus begins to rotate in the direction of rotation 7, which is preset according to the orientation of the cutting profiles 40.
  • the cutting elements 4 arranged at the opposite faces of the supporting element 5 thus make contact with the part to be processed, which is to be cut at two mutually distinct regions.
  • the particular shape of the cutting profiles 40 facilitates the penetration of the cutting elements 4 within the product to be processed.
  • the cut adjustment portion 40a allows the corresponding cutting element 4 to rest against the surface of the product to be processed, so that the rotation of the rotating body 2 makes the corresponding removal portion 40b to penetrate within the product to be processed by an extent that is a function of the curvature and size of the adjustment portion 40a.
  • the action of the cutting elements 4 during the rotation of the rotating body 2 therefore allows to remove the portion of the product to be processed that lies at the cutting region interposed between the cutting profiles 40 of each pair of cutting elements 4 and, more precisely, between the regions of contact of the cutting profiles 40 with the product to be processed.
  • the residues of the product to be worked that are removed by means of the action of the cutting elements 4 are pushed by the rotation of the rotating body 2 against the safety element 8 and consequently aspirated by the suction duct that is associated with the safety element.
  • the described invention achieves the intended aim and objects, and in particular the fact is stressed that it allows to perform a precise and delimited cut on a product to be processed, so as to remove easily and precisely the unhealthy parts that are present on food, and in particular also parts that extend deeply into such food.
  • the tool according to the invention by delimiting the cutting region in an extremely precise manner, allows to avoid the removal of the healthy parts of food that are located proximate to the portions to be removed.
