Definitions

  • the present invention mainly intends to remedy, and this using a simple and perfectly reliable machine, allowing fully automatic operation.
  • the machine according to the invention is mainly remarkable in that it firstly comprises an opening hatch device, the plate of which is formed by two tilting flaps arranged side by side with their pivot axis located at the outer edge, the edges adjacent free of these flaps being coupled to each other by two lateral hinge mechanisms. Furthermore, at least one of the flaps is associated with actuation means, for example in the form of a pneumatic cylinder, capable of moving the flap under consideration in the direction of the other kept fixed, so as to cause the opening of the hatch by progressive tilting of the two flaps to the vertical position.
  • actuation means for example in the form of a pneumatic cylinder
  • the machine shown in fig. 1 comprises a lower frame which is supposed to be constituted by two longitudinal members 1 connected to one another by two upper crosspieces 2. On these are fixed two profiles 3 with a C-shaped cross section, suitable for forming paths bearing for four rollers referenced 4 and 5.
  • the two rollers 4 are mounted idly on ends of the axle reported at the two ends of a reinforcement 6 oriented parallel to the crosspieces 2 mentioned above and welded against the underside of a flap tilting 7.
  • the arrangement is identical for the two rollers 5 carried by a reinforcement 8 fixed against the underside of a tilting flap 9, identical to the flap 7 mentioned above.
  • the two tilting flaps 7 and 9 are arranged side by side so as to form a sort of horizontal plate.
  • the reinforcements 6 and 8 which carry the rollers 4 and 5 are located in the vicinity of the outer edge of each flap 7, respectively 9, so that the assembly constitutes an opening hatch device with two flaps. It should however be observed that the two inner edges of the flaps 7 and 9 are coupled to each other by two lateral hinge mechanisms referenced 10, which maintain said edges at a certain distance from one another.
  • the hatch device thus arranged are associated with actuating means comprising two pneumatic cylinders 11 and 12, the body of which is fixed to the corresponding cross member 2 of the frame 1-2, while the end of the movable member of the piston is rendered integral with the reinforcement 6, respectively 8, of the flap 7 or 9 envisaged.
  • actuating means comprising two pneumatic cylinders 11 and 12, the body of which is fixed to the corresponding cross member 2 of the frame 1-2, while the end of the movable member of the piston is rendered integral with the reinforcement 6, respectively 8, of the flap 7 or 9 envisaged.
  • each of these cylinders 11 and 12 is connected to a source of compressed air through a system of valves not shown, suitable for ensuring the appropriate control of said cylinders.
  • the hatch device is shown in the closed position with the two flaps 7 and 9 in the horizontal top position.
  • a stack of skins A has been deposited, taking care that the median axis of said stack A coincides with the space formed between said flaps.
  • a packing box B which was supposed to be supported by an elevator C.
  • FIG. 3 shows that this movement of the flap 7 causes the opening of the hatch device: following the immobilization of the flap 9 in translation and as a result of the articulated connection operated by the hinge mechanisms 10, the two flaps 7 and 9 tilt down causing progressive folding of the stack A that they support.
  • the stack A When the two flaps 7 and 9 arrive at the end of their travel in the vertical orientation (stops 13 being advantageously provided on one of the flaps to limit the travel), being placed against one of the vertical walls of the body B, the stack A, then in the fully folded state, can slide vertically through the lower free space provided by the hinge mechanisms 10 (fig. 4) and bear against the bottom of said box.
  • the jack 12 is then supplied at the same time as the jack 11 is connected to the atmosphere, which has the effect (fig. 5) of pushing the flaps 7 and 9 towards the opposite vertical wall of the body and d 'thus spread the folded stack A against the bottom thereof.
  • the two jacks 11 and 12 are then controlled by contraction to return the device to the initial position of FIG. 4.
  • the plate formed by the two flaps 7 and 9 in the high horizontal position can receive a new stack A 'of skins to be folded and the cycle can then start again. It will however be observed (FIG. 7) that it is the jack 12 which will be controlled this time, the jack 11 remaining in the contracted position; the same folding process is carried out, but the fold is formed in the box B opposite the fold of the stack A.
  • the elevator C is controlled to descend as the body B is filled.
  • each hinge mechanism 10 is constituted by a simple link articulated at each of its ends, but it is obviously possible to have recourse to more sophisticated arrangements, allowing in particular the adjustment of the width of the free space provided between the adjacent edges of the two flaps 7 and 9.
  • hinge mechanisms 10 must be adjusted very precisely as a function of the thickness of the stacks of skins A to be folded, so that these do not slide vertically through the space free that said mechanisms spare, that at the exact moment when the flaps 7 and 9 arrive at the vertical position according to fig. 4.
  • a stack A must not fall too early (because the fold would not be placed against the vertical wall of the box B), nor should it remain applied against one of the two aforementioned flaps.
  • each of the hinge mechanisms was formed by a link 101, one end of which is coupled to a pivot of the flap 9 while the opposite end is cut out from a longitudinal slot 101a inside which can move a stud 101b integral with the flap 7. It is understood that when the cylinder 11 pushes the flap 7 along the arrow of fig. 7 to bring the two flaps vertically according to fig. 4, the lower opening provided by the mechanisms 101 has a reduced section which prevents any fall of the folded stack A. Once this vertical position has been reached, the jack 11 is actuated in the opposite direction (fig. 8), so that the stud 101b slides in the light 101a, thus allowing the two flaps 7 and 9 to move apart. on the other, which increases the section of the lower opening and promotes the passage of stack A.
  • each hinge mechanism comprises a small pneumatic cylinder 103 of the double-acting type, the body and the movable member of which are coupled to the flap 7, respectively to the flap 9, said cylinder being supplied to operate the spacing of the lower part of said flaps once these brought to the vertical position according to FIG. 4.
  • the flaps 7 and 9 are coupled to each other by hinge mechanisms 10 identical to those used in the embodiment according to FIG. 1 and 6; however one of these flaps, namely that referenced 7 in the embodiment considered, is provided with at least one pneumatic box 104 associated with a deformable membrane 104a, which in the inflated position constitutes a kind of elastically applied plunger against stacking A folded between the flaps. This stack A is thus retained in place until the box 104 is decompressed and allows retraction of the membrane 104a.
  • the system 104-104a is replaced by a pneumatic cylinder 105, the cylinder of which is carried by the flap 7, while its movable member is provided with a plate 105a, guided so as to play a role of pusher identical to that of the membrane 104a.
