Definitions

  • the invention relates to a sheet retaining member for a stacking magazine, in particular for a magazine for stacking cut sides, plates or cardboard boxes, of the type comprising an upper grid and a lower sheet retaining grid. , constituted by the rods of cylinders arranged in the front and rear walls of the magazine.
  • This stacking store includes, among other things, a front wall and a rear wall in which jacks are mounted, the rods of which, when they are advanced, constitute a first sheet retaining grid allowing the evacuation of a packet of sheets beforehand. formed on a second retaining grid also constituted by the rods of other jacks also mounted in the front and rear walls. The evacuation of the package formed on the second grid being ensured, after the rods of the cylinders of the second grid have been retracted, by a roller conveyor.
  • the jacks used in the device mentioned above are conventional jacks that can be found commercially. In particular, their rods are metallic and therefore very rigid.
  • the rigidity of the metal rods of the jacks constitutes a non-negligible drawback in that the accumulation of the sheets between the first grid, in this case the upper grid, formed by the rods of the cylinders, and the conveyor belts caused significant damage to the rods of the cylinders or, in certain cases, their rupture.
  • the resetting of the device after jamming is very difficult due to the compression of the sheets between the grid and the conveyor belts which prevents easy removal of the rods from the jacks, the latter being more or less bent or curved. and stuck in the guides of their respective cylinders.
  • Cylinders used in stacking stores are also known from documents DE-A-195 7337 and EP-A-153 983.
  • the present invention aims to remedy the aforementioned drawbacks by solving the problem posed by the permanent deformation of the rods of the jacks during jamming occurring in a stacking magazine.
  • the sheet retaining member is constituted by a series of jacks each comprising an elastically deformable rod, in a non-permanent manner, embedded at one of its ends in a piston also elastically deformable in a non-permanent manner, the rod as well as the piston of the cylinders being elastically deformable so that, during a possible jamming occurring during the stacking of the sheets on the rods of the cylinders, these rods elastically deform and are not damaged by permanent deformation and in that said elastically non-permanently deformable rod is guided, during its movement, in a bearing and by the circumferential surface of the piston sliding in the skirt of the cylinder of the jack.
  • the elastically deformable rod, in a non-permanent manner, of each of the jacks is guided, during its movement in a smooth bearing.
  • the elastically deformable rod, in a non-permanent manner, of each of the jacks is guided, during its movement in a spherical bearing.
  • the elastically deformable rod, in a non-permanent manner, of each of the jacks is made of thermoplastic polyester.
  • the elastically deformable piston in a non-permanent manner, is made of thermoplastic polyester.
  • the use of a retaining member according to the invention makes it possible to ensure a better performance of the stacking device due to the ease and speed of putting this stacking device back into service after an untimely tamping. .
  • the stacking device 1 shown in FIG. 1 comprises a series of conveyor belts 2 cooperating with a suction device 3 and a member 4 for ejecting the sheets of corrugated cardboard.
  • the sheets of corrugated cardboard, coming from a processing machine placed upstream of the stacking device 1, are transported by the conveyor belts 2 to the top of a magazine 6, formed of a front wall 7 and of a rear wall 8, in which they will be stacked after having been detached from the conveyor belts 2 by means of the ejection member 4.
  • the sheets of corrugated cardboard will be stacked on a lower grid 9 materialized by the metal rods of the jacks 10 and 11 arranged in the front 7 and rear walls 8.
  • FIG. 9 materialized by the metal rods of the jacks 10 and 11 arranged in the front 7 and rear walls 8.
  • the rods of the jacks 10 and 11 are in the retracted position because the stack 12 of sheets of corrugated cardboard already formed is represented in its phase d discharge on the conveyor rollers 13.
  • an upper grid 14, formed by the metal rods 15 and 16 of the jacks 17 and 18, is arranged in the lower vicinity of the c conveyor belts 2 so as to retain the sheets of corrugated cardboard arriving in the stacking device 1 during the time necessary for the operations of evacuating the stack 12 of sheets already formed.
  • the kind of stacking device 1 that we have just described works at high speed and there can sometimes be untimely jams due, for example, to a non-conforming or deteriorated sheet arriving in the device.
  • Corrugated cardboard is a relatively resistant material, its accumulation between the conveyor belts 2 and the rods 15 and 16 of the upper grid 14 will generate significant forces on the rods 15 and 16 and even cause permanent deformation on them, even their complete deterioration or rupture.
  • the metal rods 15 and 16 are bent under the effect of stuffing and it can be understood, obviously, that it will not be possible to actuate the jacks 17 and 18 to restore conditions normal operation by eliminating the compressed sheets between the rods 15 and 16 and the conveyor belts 2.
  • a complete disassembly of this part of the stacking device 1 will therefore be necessary and will take a long time to restore the situation. It will even be necessary, in the case where the rods 15 and 16 have undergone a permanent deformation or have been irreparably damaged, proceed to replace the cylinders concerned.
  • FIG. 2 represents, in partial section, a first embodiment of a jack 17, respectively 18, of the upper grid 14.
  • the cylinder 17 comprises a cylinder 25 closed at one of its ends by a sleeve 26 through which the fluid is supplied to this cylinder.
  • the fluid used is compressed air.
  • the other end of the cylinder 25 is, for its part, closed by another sleeve 27 in which is arranged a smooth bearing 28 serving as a guide for the rod 15, respectively 16, of the jack 17.
  • the smooth bearing 28, is preferably consisting of a socket 29 and a seal 30.
  • the rod 15 is a cylindrical rod and has mechanical characteristics allowing non-permanent deformation when it is subjected to radial forces illustrated theoretically here by the simple arrow 31. As we have previously exposed, these forces on the rods 15, 16 forming the upper grid 14 come essentially from the forces generated by the accumulation of sheets of corrugated cardboard between the conveyor belts 2 and the rods 15, 16 of the grid 14 (see FIG. 1).
  • the rod 15 is preferably made of synthetic material such as thermoplastic polyester, but one could also imagine making it for example by means of a mechanical member such as a spring with flat and contiguous turns surrounded by a sheath ensuring movement acceptable rod in plain bearing 28.
  • the rod 15 is embedded in a piston 32 where it is secured using a pin 33.
  • the piston 32 is also made of thermoplastic polyester so as to what he can also be somewhat deformed when forces are applied to the rod 15 when it occupies its advanced position.
  • the piston 32 is returned back by means of a spring 34 bearing, on the one hand, against the face 35 of the piston 32 and on the other hand against the face 36 of the sleeve 27.
  • this spring 34 to use a jack of the double-acting type.
  • FIG. 3 represents, in partial section, a second embodiment of a jack 17, respectively 18, of the upper grid 14.
  • the guide bearing of the rod 15 housed in the sleeve 27 is a spherical bearing 37 which ensures better operation of the jack during a significant deformation of the rod 15.
