Definitions

  • the present invention relates to young people; mounting and balancing device allowing the adjustment and locking in place of the knives used in the machines used for cutting, grinding and chopping food products, in particular in delicatessen and salted meats, these machines comprising a certain number knives arranged on an axis rotating at high speed a generally semi-toroidal tank.
  • the knives are placed either 180 °, 120 °, 90 °, 60 °, or 30 ° one from the other, depending on the number of knives, on a single line.
  • the adjustment is obtained by transforming the rotational movement of an adjustment washer carrying two opposite lugs in rectilinear movement, ensuring the simultaneous adjustment of two knives opposite at 180 °.
  • Balancing can be done knife by knife, or in pairs, or possibly for a complete torque set.
  • the principle is very simple and inexpensive. It is by multiplying the possible positions of weights, the number of which can also be multiple, that the desired balancing can be obtained.
  • This system has the advantage of a low cost price and great compactness. On the other hand, its precision can only be approximate and the use of multiple weights risks creating some irritating problems for the user. In addition, the compensation capacity is limited.
  • the present invention overcomes these drawbacks by creating a balancing and tightening device ensuring complete security.
  • the massive central part of the knife is pierced an opening of substantially rectangular shape to allow the establishment of a boss of square shape integral with a support washer itself pierced with an opening which the shape is identical to that of the machine shaft, the boss having an eccentric hole intended to cooperate with a finger, a balancing washer provided with a sleeve on which is placed the balancing washer of circular shape but having in its center an oblong recess thus ensuring the possibility of eliminating unbalances to achieve a balancing of the knives mounted on the machine shaft.
  • a knife known as a cutter knife 1 is shown, the shape of which is conventional, the cutting area of the knife being designated by 2.
  • the massive central part 1d of the knife has an opening 3 of substantially rectangular shape but the side 3b of which is not not parallel to the opposite side 3a but, on the contrary, moves away from right to left of the side 3b.
  • Semicircular cutouts 4, 5 are provided in the middle area of the sides 3b, 3c of the opening 3.
  • a cylindrical support washer 10 has been shown, the central part 10a of which has an additional thickness or boss 11 pierced with an opening 12 with a hexagon corresponding to the section of the drive shaft of the machine.
  • boss 11 there is provided in the boss 11 a hole 13 whose role will be explained below.
  • hexagonal hole 12 there could be an opening of another shape.
  • a circular balancing washer 15 is shown, the central part 15a of which forms a sleeve 16.
  • a stud finger 17 provided on the face of the washer 15 opposite the sleeve 16, this stud finger 17 being intended to cooperate with the hole 13 of the support washer 10.
  • a cover 30 having in section the shape of a bowl (see FIG. 10) and the central part of which is pierced with a hole 32 intended to allow the setting in place of the cup 30 on the machine shaft.
  • a fixed needle 40 which supports a cylindrical-conical piece 41 terminated, at its base, by a flange 42.
  • This cylindrical-conical piece 41 is intended to allow the mounting, adjustment and balancing of the knives which are , then mounted on the shaft 50 (fig. 12) of a cutter machine.
  • the cylindrical-conical part 41 which is in unstable equilibrium on the pointed end of the needle 40, allows precise adjustment of the knife balancing.
  • the threaded plug 45 can be screwed into the channel 46, it can be moved in height according to the setting that one wishes to make and thus adjust the sensitivity of the cylindrical-conical part 41.
  • the outside diameter of the part 41 corresponds to the diameter of the 50 of the machine.
  • the central boss 11 of a support washer 10 is placed in the opening 3 of a knife 1 so as to allow the knife 1 to be placed on the cylindrical-conical part 41, the face 41a of which has hexagon like 50 of the machine.
  • the second knife 1 with its support washer is placed, for example at 60 ° from the first knife, then the third knife 1 at 60 ° relative to the second knife, etc., up to the sixth knife 1 (see fig. 8 and 12).
  • the six knives are arranged at 60 ° from each other on the part 41 a of the cylindrical-conical part 41.
  • Each knife 1 is wedged by an intermediate part 60 relative to the corresponding washer 10.
  • the piece 60 has a substantially rectangular shape and is adjusted so as to fill the space between the boss 11 and the side 3b of the opening 3, then blocking pieces 61 are placed in the cutouts 4, 5, these pieces of blocking being small cams which can be turned using a screwdriver since they have a slotted head as shown in FIG. 8. An exact adjustment of the knife is thus obtained without risking seeing it then move on the shaft 50 of the machine since the locking pieces 61, cooperating with the intermediate pieces 60, ensure perfect attachment of this knife to the shaft 50.
  • the openings of the sleeves 16 of the balancing washers, the recessed opening 21 of oblong shape of the balancing washer and the opening 32 of the bowl 30 are provided. large enough for the shaft 50 to pass, the elements can be stacked easily on top of each other, it being understood that the hexagon shape could be modified in the event that the shaft 50 has another shape, for example a shape circular with a locking device.
  • the assembly is then balanced by slowly rotating this assembly which is locked, by the introduction into the hole 13 of the support washer 10 of the last knife placed on the shaft of the nipple 17 of the balancing washer 15.
  • the balancing washer 20 is then placed on the sleeve 16 in its neutral position and, if all of the knives 1 show a imbalance, the balancing washer 20 is correctly placed to compensate for the imbalance movement. At this time, and thanks to the screws 25, 26 the balancing washer 20 is blocked. It then remains to set up the bowl 30 so that the assembly is particularly well balanced and adjusted in layout and length. From this moment, all of the knives can be mounted on the shaft 50 of a machine eliminating all the risks caused by the centrifugal force tending to move the knives 1 longitudinally as well as by removing any unbalance causing vibrations dangerous for the machine and knives.
  • the attachment of all the knives to the shaft 50 is generally carried out by a locking nut screwing onto the threaded part 50a of the shaft 50 but other means can be envisaged.
  • the support washer 10 which has a boss 11 of square shape and in its center an opening 12 with a hexagon, allows in a simple way the use of this support washer for the installation of the knives either at 30 °, either at 60 °, or at 90 °, or at 120 °, or at 180 °, etc., from each other without any modification of the structure of the assembly since the combination of the boss 11 square with the opening hexagon ensures this division in a simple and easy way.
  • this boss 11 allows excellent guidance of each knife, the contact surface between the sides of the opening 3 and the boss 11 being larger than that currently existing between the elements allowing the mounting of a knife on a shaft. hexagon of an existing machine. This ensures better contact by a larger surface, the fatigue of the shaft 50 is therefore reduced considerably and there is less wear of this shaft and of the ball bearings maintaining this shaft.
  • the balancing washer 20 is made in one piece which was not the case in the devices comprising a balancing element since it was necessary to adjust the balancing by several separate flyweights, on the one hand, a greater trial and error and, on the other hand, a limitation of the unbalance compensations to a low value which hardly exceeds 20 to 30 grams.
  • the shim or intermediate piece 60 which is most often made of mild steel easily ground or filed, allows exact and very quick adjustment even in precarious working conditions.
