Definitions

  • the object of the present invention is to provide a machine in which the skins to be stacked are raised, using appropriate means, on a number of trains of rotating rollers, which trains are mounted on a continuous moving chain in a closed circuit. on itself, for example with a rectangular profile, in order to allow the skins to be deposited on a stacking plate while being oriented either all in the same direction, or in alternating directions, or even in contact flower against flower and flesh against flesh.
  • Appropriate stop mechanisms for example constituted by jacks, ensure the immobilization of the drive belt of the rollers during the advance of the transfer chain, in order to operate the unloading of the skins on the tray. stacking as said chain advances.
  • Another stop device provided immediately below the transfer ribbon and in front of the stacking plate, intervenes to bring the skins down on top of each other in an inverted arrangement, so as to put flower against flower in contact or flesh for flesh in each successive pair of skins, this provision being sometimes necessary taking into account particular treatment requirements.
  • the machine may include two or more of two movable support planes of the skins to be stacked, in order to increase the production capacity of the assembly while maintaining the characteristics previously described with regard to each of the stacking plates.
  • one of the roller trains is provided with toothed wheels disposed on one side, while the following train comprises these toothed wheels on the opposite side.
  • These roller trains mesh with appropriate racks, supported by a control system preferably of the deformable parallelogram type, in order to ensure the rotation of all the rollers of a train for the desired time.
  • the rack devices are two in number to correspond to the two sides of the assembly, thus being able to act independently on one train or the other and thereby giving the possibility of unloading a skin with the first train of rollers in motion, while the second train rises by moving the skin which will then be unloaded during the next phase.
  • the stacking of the skins with flower against flower or flesh against flesh contact is capable of being carried out even in this variant of construction of the machine, by using a second transfer mat on which the skins coming from the main mat of loading of the machine, making it return to the level of the transfer rollers to be superimposed on the second skin and of course reversing the direction of travel while lifting the conveyor belt on one side to allow access to it in a position superimposed on the next skin.
  • the stacking machine comprises four successive trains of rollers, respectively referenced 1, 2, 3 and 4 and mounted one after the other by defining a rectangular profile and being separated by a free space suitably calculated in view of allowing the skins to be unloaded onto the stacking plate 5.
  • Idler gear wheels 6, 7, 8 and 9 cooperate with an actuation chain 10 which ensures the movement of the aforementioned rollers and which is controlled by a electric motor 11 associated with a belt or chain transmission 12.
  • Two small jacks 13 and 14 ensure, when desired, the immobilization of the transfer belts mounted on the four roller trains which are thus likely to advance by turning either in the opposite direction if one acted on the jack 13, or in the same direction if one acted on the jack 14.
  • An inclined plane 15 pivotally mounted makes it possible to load the skins on the rollers during their advance. This inclined plane can however be eliminated when the loading is carried out by a machine arranged upstream or by a conveyor belt independent of the machine itself.
  • FIG. 3 shows a first pair of rollers 1 mounted idly on support shafts 16 which are provided with toothed wheels 17 cooperating with a chain 18, while the transfer chain 19 is fixed on axes 20 provided projecting from the ends of the trees 16 above.
  • rollers 1 are profiled so as to have projecting and depression parts which are alternated with respect to the adjacent rollers, in the manner shown in FIG. 3.
  • these rollers can be hollowed out with grooves 21 which receive elastic rings 22, which form guides for the belts 23 which constitute the conveyor belt, it being observed that this can be constituted by a single element .
  • the machine is provided double in order to be capable of carrying out the simultaneous loading of two stacking plates respectively referenced 24 and 25.
  • the stacking system comprises in such a case six trains of rollers 26 and two pairs of jacks stop tires referenced 27 and 28 for the plate 24, 29 and 30 for the plate 25.
  • the transfer ribbon provided at each train of rollers, it can take the form of a series of elementary ribbons 23 according to FIG. 4 as that of a single element which surrounds the rollers of each train. In this case, it is no longer necessary to rotate all the rollers; one can be content to train only the first, because the ribbons which are mounted on said rollers also serve to transmit movement to others.
  • the subsequent train 2 If during this stacking phase the subsequent train 2 is left free, it will continue with the next skin until it comes in superposition on the plate 5 on which it will then unload the skin with the same orientation as the previous one. Under these conditions, the skins will overlap one another, all being oriented in the same way.
  • each train of rollers ensures the constitution of a corresponding pile by skipping the preceding batteries and by operating in each stack a stacking in identical superposition or alternating, depending on the actuation of the stop cylinders 27, 28, 29 and 30.
  • the speed of rotation of the elementary rollers can be identical to the speed of advance, but it can also be different by modifying the diameter of the pinions which join these elementary rollers.
  • double-width machines can be produced, equipped with rollers which make it possible to simultaneously treat skins arranged side by side and intended to constitute two adjacent stacks.
  • rollers of the four trains 31, 32, 33 and 34 are prevented from rotating by racks 35 and 36 which act alternately on one train of rollers or on another depending on the side where said rollers comprise the cogwheels.
  • Another transfer mat 39 provided after the introduction conveyor 40, can be raised or lowered by a jack 41 by turning around a pivot 42, so as to allow a first skin to mount on the mat 39 when the latter is in the lowered position, while then this mat 39 is raised by actuating the jack 41 and, by reversing its direction of movement, causes the skin to rise on the train of rollers 31 surmounted by a second skin coming from always carpet 40, the skins being in such a case in contact flower against flower or flesh against flesh, or alternatively.
  • the mat 39 is not used and remains in the raised position when the skins are to be stacked, all being oriented in the same direction.
  • the machine according to the invention can be provided with detection means, for example photoelectric cells, to detect the arrival of a skin and start the ribbons which in this way stop when no skin to be stacked comes from previous operations, while when the skins are brought regularly to close distances, the whole remains in permanent operation without ever Stop.
  • detection means for example photoelectric cells
