Definitions

  • the present invention relates to improvements in cleaners, transporters, ginners and calibrators of vegetables or fruits, such as potatoes, carrots, onions, endives, beets, oysters or the like, consisting of parallel trees in the same plane, all rotating in in the same direction and carrying equidistant discs or cogwheels or stars, the change in size being effected mechanically by varying and adjusting the distance between the axes of the shafts, this distance generally being greater and greater from upstream to 'downstream of the machine to let between products larger and larger products, each of the trees, held in a frame, being driven in rotation.
  • Transporter cleaners have been proposed, the center distance of the rollers of which can vary with a gear wheel control device in which the intermediate pinions can rise on the perpendicular bisector of the segment separating two axes of the consecutive rollers. This is achieved by V-shaped levers or even crossing levers.
  • V-shaped levers or even crossing levers we come back to the disadvantage of the pinion drive which was mentioned above.
  • the present invention is intended to remedy these drawbacks.
  • the device of the invention allows a continuous and uniform adjustment of the spacing between rollers even during operation of the machine.
  • the chain drive is reliable and silent and, despite the variations in its travel, only a small tensioner is needed. Indeed, during the elongation of the device, the bending of the chain is less important and it elongates little; while during the shortening of the device, the chain traverses zigzags at more pronounced angles.
  • the star-shaped discs or V-shaped discs make square openings for the passage of products, square openings whose sides enlarge when the trees are spread in a diagonal direction. these squares.
  • Adapting the movement of the deflector shafts by extending the telescopic device has the advantage of having a fixed feed point without modifying the length of work.
  • the machine consists of a number of parallel shafts, in this case, from 1 to 14, but which can be decreased or increased and whatever the quantities, are located in the same plane and all rotate in the Same direction.
  • On these shafts are threaded discs 15 with a V profile, so that they have an edge (16).
  • These discs are advantageously made of elastomer so that their rotation causes the vegetables or the like to be shaken without damaging them.
  • FIG. 5 two trees (2, 3) have been shown as close together as possible so that the edges (16) of the discs (15) of two adjoining trees almost touch each other while in FIG. 6 the two trees have been represented (2 and 3) separated so that the edges (16) are at a certain distance from each other.
  • FIG. 5 two trees (2, 3) have been shown as close together as possible so that the edges (16) of the discs (15) of two adjoining trees almost touch each other while in FIG. 6 the two trees have been represented (2 and 3) separated so that the edges (16) are at a certain distance from each other.
  • the rotation of the shafts (1) is ensured by a geared motor (21), which controls one of the shafts, the movement being communicated to the other shafts by a kinematic chain which, in the known examples, consists of a cascade of pinions.
  • the assembly is held by a chassis (22), of which the side members are recognized at (25), (24).
  • a first characteristic of the invention consists in the fact that the bearings such as (25), (26) of the shafts (1) to (14) are supported and guided by the central median articulations and aligned levers inclined relatively to the right and to the left such as (27) and ( 28). Each of these levers is articulated at its end to the neighboring lever inclined in the other direction.
  • This arrangement of equal levers articulated in the middle part and at the ends is very old and is sometimes known as the "Nuremberg chisel". This arrangement forms a series of equal deformable diamonds, all of which therefore have the same diagonals.
  • each of the shafts (1) to (7), on the one hand and (8) to (14), on the other hand, which form part of two different lever systems is always the same and varies between a maximum distance shown in Figure 1 and a minimum distance shown in Figure 2.
  • Each set of levers (27, 28) includes a fixed point which are the axes of the shafts ( 7), (8) and a lever which moves with the greatest) amplitude which is, on the one hand, the lever (271) and, on the other hand, the lever (281).
  • the shafts (1) to (14) are held in the same plane by guiding between slides (77), (78).
  • the levers (271) and (281) are separated or brought closer by a system of connecting rods (29), (30) articulated in (31), 5 (32) respectively with the levers (271), (2ôl) and in (33) , (34) to a lifting beam (35) (which can be doubled ensuring two different calibers on the same machine, therefore two control cranks, and which can be made possibly integral) oscillating itself around a axis (36) integral with a support (37) fixed to the beam (23).
  • the oscillation of the lifter (35) is ensured by a nut integral with said lifter in which is screwed the threaded end (3S) of a crank (39) rotating in a thrust bearing (40) fixed on the frame (22).
  • each crank (39) oscillates in one direction or the other, one or two spreaders (35) by pushing or pulling the rods (29) or (30) which act themselves on the levers (271) and (281) to either remove the series of levers according to the arrows (41, 42) ( Figure 1), or bring them together according to the arrows (43, 44) ( Figure 2).
  • a discharge deflector (49) is fixed on the last lever (27) directed towards the bottom of the shaft (14) corresponding to the other series of crossed levers.
  • the shafts (7) and (8) of the machine ( Figures 3 and 4) have at their end a pinion wedged on them such that (57) which is engaged with a chain (58) ( Figure 1 and Figure 2) so that the synchronous rotation of the two shafts (7) and (8) is ensured.
  • all the other shafts (1) to (14) have at one end a pinion such as (59) wedged on the tree and at the other end, a idler pinion (60). Odd shafts have idler gears on one side of the machine while even shafts have idler gears on that same side. It is the opposite on the other side of the machine.
  • an endless chain such as (61) which, on one side of the machine, passes over all of the fixed pinions (59) and below all of the idlers (60).
  • an endless chain (62) or a belt which passes beneath all of the propelled sprockets of the shafts and above all of the idler sprockets.
  • the chains (61) and (62) therefore rotate in opposite directions.
  • the chain (61) drives the fixed sprockets of the shafts from above, while the chain (62) drives them from below. They are each held at one end by a gypsy (63) and, at the other end, by a pinion (64) held at the end of an oscillating lever (65) and which is recalled in the direction of the arrows ( 66, 67) by a spring (68) held around a rod (69) attached to the chassis (22), the assembly serving as a chain tensioner.
  • This drive of the shafts (1) to (14) is very regular and is done without noise, especially if endless chains (61), (62) with rollers are used, the technique of which is well mastered, in particular in motorcycles.
  • this drive device is not exclusive and one could use belts which could function in good conditions if one could avoid the sliding of said belts on the pulleys replacing the pinions wedged on the shafts (1) to (14) .
  • the mechanism is protected towards the outside by protective casings (71), (72) (FIG. 7) and, on the inside of the machine, by flaps (73), (74) which are oblique and flexible, for example of rubber, and which are fixed above the shafts to the walls (75), (76) of the chute formed by the machine.
  • the lower end of the flaps (73), (74) touches the shafts (1) to (14) and the end discs (15) which they support.
  • the machine is used for cleaning, transport and calibration all kinds of vegetables, such as potatoes, carrots, onions, endives, beets or others. It can also be used for the same purpose with regard to fruit and even seafood, for example oysters.
  • the space between discs or stars is therefore cleaned by a comb comprising as many teeth directed upwards as there are spaces between the discs (15) and the spacing of which corresponds precisely to the spacing of said discs. spaces.
  • This comb is held on slides parallel to the plane of the rollers so as to be able to move parallel to itself and parallel to the shafts (1) to (14), under these so that the teeth of the comb are introduced between the disc spaces (15).
  • Each end of the comb, near its slide, is main-) held by an endless chain returned, at each end of the machine, by a pinion wedged on two shafts. The rotation of these shafts, in one direction then in the other, displaces the chains and the comb from one end to the other of the machine in both directions while carrying out the planned cleaning.
  • the machine can be composed of several successive groups of rotary rotary shafts (1) to (14), each group being adjusted for a different rating on this same machine.
  • the caliber change can be carried out either independently of the other groups, or mechanically and simultaneously.
