Definitions

  • the invention belongs to the field of cutting cheese wheels, with a view to in particular to obtain whole or point portions, that is to say made up of pieces extending over the entire thickness of said wheels.
  • the cheese wheels in question have a shape generally cylindrical, the two bases of which are sometimes domed.
  • the first of these consists first of all in carrying out a central core drilling within the grinding wheel, by means of a circular blade, i.e. to remove the heart from the grinding wheel so as to obtain a crown, then to position said crown on a turntable, in order to subject it to the action of a single fixed blade operating on the guillotine principle, and actually generating portions in accordance with the wishes of users.
  • the cutting of grindstones into portions in accordance with the invention requires less constraints in terms of sizes of said grinding wheels compared to known prior techniques, templates which are known to be likely to vary from one wheel to another, and a fortiori from one type of cheese to another.
  • This type of cutting also allows adaptation of the portion size according to the radius of the grinding wheel.
  • the half-wheels thus obtained are measured at several points, in particular in diameter, and in height, so as to optimize the variation of the pitch of rotation of the half-grinding wheel, during its radial cutting, to result in a better dispersion thereof.
  • the movable blade constituting the radial cutting member is fitted with an ejector, intended, when said blade is at the end of its travel, to push the radial portion then produced on a conveyor for discharging said portions.
  • the radial cutting device is associated with a centering or off-centering the half-wheels with respect to a fictitious vertical axis, parallel to the radial cutting axis of the cutting device, i.e., relative to to a homothetic frame of reference of the radial cutting frame.
  • This organ of centering is in fact located in the extension and just upstream of the radial cut. In this way, it is possible to modify the coring carried out at the level of said cutting tool, and therefore modifying the resulting crown, in order to adapt the profile of the latter at the desired weight of the final portions.
  • the installation according to the invention is in particular intended to be put in place after a wheel transfer device, for example conveying said wheels from a storage or maturing cellar, first to a washing station, then to a cutting area.
  • a wheel transfer device for example conveying said wheels from a storage or maturing cellar, first to a washing station, then to a cutting area.
  • the diameter wheels as well as their thickness or height can vary from one to the other according to a certain proportion.
  • the installation - object of the invention has a certain flexibility in terms of size range, allowing good adaptation to dimensions of the grinding stones to be treated.
  • each of the grinding wheels undergoes a diametrical cutting, the torques half-grinding wheels (2) thus formed being brought to the cutting device automatic according to the invention via a conveyor (1).
  • a separation member (not shown), which first of all separates the two half-wheels and moreover, ensures their respective rotation of 90 °, so that the operator, placed along one of the sides of said conveyor, can perform a visual sorting, so the case remove any non-conforming grinding stones.
  • the half-wheels (2) are then conveyed by the conveyor (1) to a device (3) radial cutting, intended to produce within them point portions, corresponding to a crown sector, as will be described below.
  • This device (3) is oriented perpendicular to the conveyor (1) and comprises advantageously a centering member (5), as can be seen in the figures 1 and 2.
  • This centering member (5) is intended to modify the positioning of the half-wheel (2) prior to its cutting into points, depending in particular on its dimensions and desired average weight of said spikes.
  • this organ (5) is automatically managed by a programmable controller or equivalent, which, depending parameters entered (e.g. portion weight) and measurements performed (diameter and height of the half-wheels), will induce centering or off-center the half-wheel relative to a fictitious axis parallel to the cutting axis radial described later.
  • the radial cutting station being aligned with the centering, the half-wheel retains the orientation given to it at its level of its passage to the centering station.
  • the installation comprises a member pusher (4), moved in translation by any means, in particular electric, and comprising two spaced fingers (4a).
  • the centering member (5) has a plurality of rollers or cylinders horizontal (6) free in rotation and parallel to each other, at the level of which install the half wheel (2).
  • the member (5) also includes pawns respectively lateral (7) and frontal (8) intended to modify the centering of the half-wheel relative to a fictitious axis, supposed to correspond by translation to the axis of effective rotation of the cutting plate described below in more detail.
  • the side pins (7) consist of a roller mounted idle in rotation on a vertical axis secured to a support (20). Both supports are likely to be animated by a translational movement, antagonistic relative to each other. To do this, they are each fixed at the end of two parallel racks (16), each guided by two sets of two rollers (17) (see Figure 4), and cooperating with pinions (18) common to the two racks, such so that the translation of one of the racks. in a sense, drives the translation on the other in the opposite direction.
  • the front pawns (8) for example seven in number, also consist each of a roller mounted idly in rotation on a vertical axis, and connected to a bar (21) horizontal, capable of being moved up and down under the action of a hydraulic or pneumatic cylinder (22), and two columns of guide (23).
  • the front pins (8) are positioned under one cylinders or rollers (6) on which the half-wheel rests at the level of the member centering (5), in particular under the penultimate, to which they are connected by bearings (24) integral with the bar (21), thus allowing the half-wheel to slide on the rollers (6), while in the raised position, said front pins (8) provide the positioning in abutment of the half-wheel, for its centering.
  • the centering of the half-wheel depends on the measurements carried out prior to its routing at this level by probes, measuring on the one hand, the diameter of the half-wheel and this, in at least two different places of it, and secondly, its height. Using this data, and parameters entered by the user, it is then possible to determine the number of divisions, ie radial cuts to be made within the grinding wheel according to the weight nominal of each portion sought.
  • This centering member (5) is therefore actuated so as to obtain portions from the outer ring of the half grinding wheel, produced during the cut, of balanced size according to the radius of the grinding wheel.
  • the half-wheel thus centered is pushed again by the pusher member (4) at the level of the actual cutting member (9).
  • the half-wheel is then held firmly on a plate (10) by means of two peaks (25) passing through it, said peaks being actuated by a vertical cylinder (26).
  • This plate (10) is actuated in translation by a carriage (27) controlled by a system screw-nut (28), connected to an electric motor (29) or equivalent.
  • this fixed blade is at least as high as the maximum height of the half millstones.
  • the coring thus produced of the half-wheel defines an outer crown, of which the dimensions are a function, on the one hand, of the dimensions specific to the half-wheel, and on the other hand, characteristics of said coring. These are directly dependent on the orientation given to the half-wheel during the previous phase of centering or off-centering, taking into account the fixed nature of the fixed vertical blade (11).
  • the cutting member also comprises a movable blade (12) radially by compared to the crown from the half-wheel.
  • This blade (12) is actuated by the through an electric motor (15) and through a typical assembly crankshaft (14), constituted by a wheel actuated in rotation by a motor, and on which is fixed a connecting rod (13), the other end of which is secured to a carriage (30) carrying said movable blade (12), so as to ensure a radial cut of said crown.
  • the direction of movement of this blade is therefore substantially perpendicular to the fixed blade (11).
  • a pallet (31) coming to rest against the cut face of the half-wheel at one of the ends, ensures the rotation of the latter according to a determined value, in order to allow the cutting of a portion of dimensions also determined.
  • the pallet (31) is connected by means of an arm (32) to a toothed crown (33), centered on a bearing (34) and meshing on a pinion (35) integral with the output shaft of a stepping motor (36).
  • the actuation of this motor (36) is controlled by a programmable controller, depending on the parameters found at the centering. It is the same with regard to the adjustment in position of the plate (10).
  • the stroke of the movable blade (12) is such that it comes flush with the fixed blade so to ensure a clean slicing of said portions.
  • the movable blade (12) is provided with a spacer (not shown), intended to fold the slices or portions as soon as they are cut on a conveyor (37) positioned in the immediate vicinity of the radial cutting member (9), in order to ensure the evacuation of the portions so cut towards the weighing and packing place, and more general way of packing.
  • the core drilling carried out by the fixed blade is unloaded automatically without operator intervention of the cutting member (9) on a belt conveyor (38). It can be routed to a device for cutting portions well known in self, or on the contrary, be transferred to a grated cheese maker.
