Definitions

  • the present invention relates to a pallet, that is to say a tanning machine comprising two plates provided with teeth and arranged one above the other, which plates alternately approach or move away from it. one of the other.
  • Pallids are used at the end of the drying operation in order to pull the skin in all directions with violent stresses, so that said skin can regain flexibility and softness.
  • the other plate Opposite each of the teeth of one of the plates, the other plate has a recess inside which the abovementioned tooth penetrates during the phase during which the two plates are closest together.
  • one of the two plates is fixed by being made integral with the structure of the machine, while the other is assigned the role of performing the entire alternative race.
  • Such a device is described in GB-A-1 448 355.
  • the system most often used to move the movable plate is formed by a rod-crank type device arranged at one of the two edges of said plate.
  • Such a device has the serious disadvantage of requiring very robust connecting rods, of large dimensions, since it is essential that the movable plate be applied against the fixed plate with high pressure; hence the obligation to have to move considerable masses which are difficult to balance, so that the working speed is necessarily limited, which affects the productivity of the machine itself.
  • the present invention proposes to make a pallet equipped with an animation system thanks to which it is possible to exceed the limitations devices of known type.
  • the pallet according to the invention is defined in claim 1.
  • the displacement of the bottom plate of the palisson is obtained using one or more pairs of rods oriented substantially vertically, which, at their opposite ends are respectively articulated to the base of the machine and the movable plate and which at their other ends brought into reciprocal contact, are themselves articulated to each other.
  • the movable plate is guided so that its movements can be carried out alternately upwards and downwards.
  • the pairs of rods are arranged in two distinct groups, each of these comprising one of the arms indicated above and being placed in lateral position with respect to two eccentric elements, provided at the central part of the machine and to each of which is articulated an auxiliary arm itself articulated by its end opposite to one of the aforementioned arms.
  • the movement of the eccentric elements determines the horizontal translation of the arms, which causes the arms to reconcile and move apart alternately and therefore generates the inclination of the rods relative to the vertical and, in the final analysis, the lowering and the raising alternate of the bottom plate.
  • the device according to the invention makes it possible to obtain very simply the balancing of the masses in movement, so that the working speed of the machine can turn out to be much higher than that which can be obtained with conventional devices.
  • the palisson comprises an upper plate 1 superimposed on a lower plate 2, these two plates having in correspondence on their faces opposite the teeth 3 to which correspond on the opposite plate cavities 4.
  • the skin is intended to pass into the space between the two plates and is then subjected to a tensioning action exerted by the teeth 3 of said plates.
  • the upper plate 1 is fixed by being made integral with the support structure 10 of the machine, while the lower plate 2 is movable.
  • the displacement of this lower plate is obtained by means of one or more pairs of rods 5 'and 5'', oriented substantially vertically below said plate.
  • the lower rod 5 '' is articulated at 6 to the fixed structure 10 of the machine, as well as at 7 at the lower end of the upper rod 5 '.
  • the latter is itself articulated at 8 by its end opposite to the lower plate 2.
  • a guide support 9 integral with the structure 10 of the machine and suitable for allowing said lower plate only a reciprocating movement oriented vertically.
  • the fundamental condition for the functioning of the device lies in the fact that the upper rods, like the lower rods, must be arranged in parallel.
  • the essential characteristic of the invention consists in the fact that the lower rods 5 '' are forced to perform an alternating movement centered on the hinge 6, so that the hinge 7 travels a short arc.
  • the presence of the arm 11, in the case where more than one pair of rods has been provided, is essential to guarantee the concordance of the phases between the different pairs of rods, as well as to allow the setting in movement by means of a single device.
  • a flywheel 12 is placed on which articulate at 13, symmetrically with respect to the axis of said flywheel, two auxiliary arms 14 whose opposite ends are articulated at 15 to the arms 11.

Claims (4)

  1. Stollmaschine, bestehend aus einer oberen Platte (1), die über einer unteren Platte (2) angeordnet ist, wobei die beiden Platten auf der Ebene ihrer einander gegenüberliegenden Flächen Zähne (3) enthalten, denen eine Reihe von Vertiefungen (4) auf der gegenüberliegenden Platte entsprechen, wobei die untere Platte (2) durch mindestens ein Paar unter dieser Platte vorgesehene Stangen (5' und 5'') im wesentlichen senkrecht zur Maschine verschiebbar ist, und wobei die Stange (5') ihrerseits durch ein Scharnier (8) mit der unteren Fläche der unteren Platte (2) verbunden ist, dadurch gekennzeichnet, daß die untere Stange (5'') durch ein Scharnier (6) mit der Fußplatte der Maschine verbunden ist, während sie mit ihrem oberen Ende mittels eines Scharniers (7) zur Führung der genannten Platte (2) mit der oberen Stange (5') verbunden ist, indem sie lediglich dieser Platte (2) gestattet, sich im senkrechten Sinne zu verschieben, wobei ein einzelner horizontal ausgerichteter Arm (11) vorgesehen ist, in den die verschiedenen Scharniere (7) eingesetzt sind, um die beiden Stangen (5' und 5'') eines Paares zu verbinden, wobei ein an zwei Hilfsarmen (14) befestigtes Schwungrad (12) dazu dient, eine abwechselnde Bewegung der Stange (5'') um das Scharnier (6) auszuführen, so daß das Scharnier (7) abwechselnd einen kurzen Kreisbogen durchläuft.
  2. Stollmaschine nach Anspruch 1, dadurch gekennzeichnet, daß sie unterhalb der beweglichen Platte (2) Mittel (16) besitzt, die dazu bestimmt sind, die Platte (2) gegen die obere Platte (1) zu drücken.
  3. Stollmaschine nach Anspruch 2, dadurch gekennzeichnet, daß die verschiedenen Paare von Stangen (5' und 5'') in zwei Gruppen unterteilt sind, die beidseitig des mittleren Teils der Maschine angeordnet sind, wobei die Stangenpaare jeder dieser Gruppen gegenseitig untereinander mittels eines Armes (11) verbunden sind, der die Scharniere (7) enthält, die die Stangen desselben Paares mit den im mittleren Teil der Maschine vorgesehen Mitteln (12, 13, 14, 15) verbinden, um die abwechselnde Bewegung der Annäherung und Entfernung beider Arme (11) durchzuführen.
  4. Stollmaschine nach Anspruch 3, dadurch gekennzeichnet, daß im mittleren Teil der Maschine ein Schwungrad (12) angeordnet ist, das sich um eine Horizontalachse dreht und an dem mittels Scharnieren (13), die symmetrisch in bezug auf die Achse des Schwungrades angeordnet sind, zwei Hilfsarme (14) befestigt sind, deren entgegengesetzte Enden durch Scharniere (15) mit den Enden der Arme (11) verbunden sind.
