Definitions

  • the present invention relates to a process for cutting into radial portions round and flat cheese wheels such as emmental wheels. and a device implementing the method.
  • a wheel of Emmental weighs typically between 75 and 80 kilograms due to the economy of manufacturing this type of cheese.
  • the cutting of such a cheese is generally carried out radially from the periphery of the grinding wheel to its center, using tools that are mostly manual or wire, so as to obtain elementary portions in the form of sectors of a circle. .
  • cutting operations are commonly carried out on the ground, the grinding wheel being held vertically between the legs of the preparer who is responsible for the detail of the cheese.
  • the invention provides precisely a solution to these problems which relate to the cutting into radial portions of round and flat cheese wheels, such as emmental or county wheels, characterized in that said wheel, held vertically on a holding device comprising rolling means on which it centers and can rotate freely along its horizontal axis, being enclosed in a mobile frame in rotation, on the holding device, around a horizontal axis passing through the center of the grinding wheel, is cut into radial portions by any known means, with blade or wire, from a first cutting zone close to the movable frame and progressing, in the same direction of rotation, to the two approximately a third of the circumference of the grinding wheel, the remaining third, reassembled by a rotation of the movable frame in the opposite direction to the cutting direction, then coming into positive abutment on a vertical stop provided for this purpose, thus allowing an integral cutting of the cheese wheel.
  • the invention also relates to a device for holding a simple and new cheese wheel which is characterized in that it comprises two feet held parallel, in a horizontal plane, by two cylindrical spacers around which rollers can rotate freely , each foot supporting a telescopic upright extending vertically equidistant from the two spacers and provided, at its upper end, with means of articulation of a movable frame consisting of two substantially coplanar arms of adequate shape to grip the grinding wheel to be cut , clamping and blocking means being provided to make the grinding wheel integral with the frame thereby allowing the angular displacement of the grinding wheel resting and rolling on the rollers, its cutting position then being determined by means such as chain or stop.
  • the mobile frame articulated on the upper ends of the vertical uprights integral with the feet of the device, consists of two arms each having a profile and its own function: a first arm is articulated on a first vertical upright, at one of its ends, thanks to an advantageously threaded axis allowing, in cooperation with a clamping lever, a punctual tightening of the arm on the upright.
  • this arm is a simple bar, preferably made of stainless metal, extending in a rectilinear fashion and provided, at its free end, with a perpendicular axis and integral with said arm; this axis comprising a thread and having a length substantially equal to the average width of the grinding wheels, comes to cooperate with the second arm of the movable frame, articulated on the second vertical post, to enclose the grinding wheel radially by means of a clamping lever.
  • the movable frame fits as well as possible the surface shape of the grinding wheel and, in this regard, provision has been made, on the one hand, to give the second arm a curved shape, increasing the zones of contact with the grinding wheel and, on the other hand, to regularly have, on the internal faces of the two arms in contact with the grinding wheel, breaks in continuity, such as claws or points, which, by penetrating into the cheese crust, increase the adhesion of the frame to the grinding wheel.
  • the articulation of the second arm on the second upright comprises means of linear and horizontal displacement on the axis of rotation coming apart the upright of the arm which can thus adapt exactly to the 'thickness of the wheel.
  • the two vertical uprights can have a free movement in the vertical direction so as to compensate at any time for irregularities in the shape of the grinding wheel when it has been rotated on itself by means two lines of lower rollers on which it rolls and centers itself automatically in relation to the vertical plane of the uprights.
  • the latter are moreover provided with tightening keys preventing any vertical movement, making it possible to raise the grinding wheel which can thus escape from its support on the rollers which would detrimentally mark said grinding wheel in prolonged parking, for example during the rest times.
  • the grinding wheel to be detailed is cut radially into successive sectors from a first cutting zone close to the arms of the frame; the cut is always made in the same direction and the imbalance created by the removal of material brings the cutting plane substantially back into the operating area, and this to an extreme position corresponding substantially to the cutting of two-thirds of the wheel.
  • the operator has the advantage of raising the third of the grinding wheel remaining in the lower part of the device which hinders and complicates the cutting.
  • a vertical stop fixed to a foot and on which the first arm of the movable frame rests when the preparer returns, by rotation of the movable frame in opposite direction to the cutting direction, the third of the grinding wheel remaining in the lower part so as to arrange it in upper part and thus facilitate its work.
  • the height of said stop is such that the plane of the movable frame, pressing on it, has a downward inclination of about 30 ° relative to the horizontal.
  • the holding device according to the invention is advantageously completed by an inclined plane from an area close to the ground to the plane of the pebble lines: thus is it possible to bring the cheese wheels for the position between the rollers.
  • the process for cutting round and flat cheese wheels can take place in three main stages.
  • the grinding wheel 1 to be detailed is brought to the holding device by rolling it vertically up to a ramp access 2 allowing the grinding wheel 1 to come to center on two lines of lower rollers 3, of transverse axes, between two vertical uprights 4, the rollers 3 and uprights 4 being carried by a lower frame bearing on the ground.
  • the grinding wheel 1 is gradually cut according to successive radial cutting planes in the direction of the arrow C in FIG. 1B, the grinding wheel 1 refocusing after each cut by rotation on itself according to the arrow M, being guided by the rollers 3 by the unbalance effect created by the removal of the material, successively to an extreme position corresponding substantially to two thirds of the circumference of the grinding wheel 1.
  • the part of the grinding wheel remaining to be cut is brought to the upper position as shown in FIG. 1C, by a simple rotation in the anticlockwise direction of the movable frame 5 tightening the remaining part of the grinding wheel, as indicated in FIG. 1C, until the movable frame 5 comes to rest in abutment on a vertical stop 6.
  • the cut along the radial plane F can resume and progress in the same direction as in the first step following the arrow C counterclockwise.
  • the holding device according to the invention is shown in top view in Figure 2, and it is supported by two legs 7.1 and 7.2 consisting of two cross-section beams in an inverted "U" section, extending side by side in a horizontal plane, and held in parallel, with a spacing substantially greater than the thickness of the grinding wheels 1, thanks to two transverse spacers arranged symmetrically with respect to the median axis of the support thus produced.
  • These spacers advantageously constitute axes 8 which are provided to each receive two rollers 3 which can rotate freely and intended to support the grinding wheels 1.
  • the rollers 3 are preferably made of food-grade plastic and they are conventionally mounted on ball bearings and axially maintained on their axes 8 by spacers 9.
  • each upright 4.1, 4.2 consists of a first upper tube 10 of square section which slides outwardly along a second tube 11 welded, at its lower end, to one of the legs 7.1,7.2.
  • the amounts 4.1 and 4.2 can thus, to a certain extent, vary in height to be constantly adapted to the radius of the grinding wheels to be cut into vertical portions.
  • the sliding of the tubes 10,11 can be blocked by a counter-clamping device as shown in detail in Figure 4 for the amount 4.2.
  • the vertical sliding blocking system is obtained by a counter plate 12 housed inside the tube 11 and comprising perpendicularly a threaded axis on which a lever 13 clamps the tubes 11 and 12 preventing their relative displacement.
  • the axis 14, carried by the amount 4.1 ensures the articulation of a first arm 16 which can rotate freely on this same axis 14 or be pressed against the amount 4.1 by means of a lever 17 which can be screwed on a external threaded part of the axis 14.
  • the arm 16 of the movable frame 5 comprises a rectilinear part, preferably made of stainless metal, of sufficient section to radially hold a cheese wheel 1 and of length substantially greater than the radius of said wheel 1.
  • a threaded axis 18 which constitutes the transverse part of the frame 5 extending over a width substantially greater than the thickness of the grinding wheel 1.
  • the other axis 15, carried by the upright 4.2, ensures the articulation and the displacement of a second arm 19 of the movable frame 5.
  • the internal end 151 of the axis 15 comprises a ball joint 20 blocked in translation by two circlips 21 secured to the arm 19 according to a well known assembly. In this way, the axis 15, threaded, can move inside a threaded sleeve, integral with the upright 4.2 and move the arm 19 on the ball 20 in horizontal translation.
  • the arm 19, of section identical to that of the arm 16 has a curved portion 191 to match the shape of the flat front face of the grinding wheel 1 thus increasing the contact area and therefore the connection between the frame 5 and the grinding wheel 1.
  • the end portion 192 of the arm 19 extends parallel to the direction of the arm 16 and it is provided with an oblong hole 22 receiving the axis 18 which will come to clamp the two arms 16 and 19 around the grinding wheel 1 by screwing d 'a lever 23, in contact with the end portion 192 of the arm 19, on the threaded axis 18.
  • the stop 6 extends horizontally over a height corresponding substantially to half that of the upright 4.1. This stop 6 is welded to the internal face of the foot 7.1 substantially in line with a line of rollers 3. The stop 6 can then serve as positive support for the arm 16 of the movable frame 5 when the latter supports the last third of the grinding wheel to be cut 1.
  • the access ramp 2 is advantageously arranged between the feet 7.1 and 7.2 so as to facilitate the entry of the grinding wheel 1 from the ground to the cutting area between the two lines of rollers 3.
  • the ramp 2 is a simple sheet metal, preferably stainless steel.
