Definitions

  • the invention relates to a device for fixing a plate to a cylinder while allowing rapid control, at certain times, of the application and fixing of said plate on a determined angular portion of this cylinder and, d 'other times, the release of this plaque.
  • the plate is held on the cylinder by mechanical tensioning means, such as flanges gripping the ends of the plate or by magnetic means.
  • One result which the invention aims to obtain is such a device which ensures both perfect application of the plate on the cylinder and rapid erasure of the plate in order to release the cylinder.
  • the machine comprises a cylinder 1 on an angular portion "A" of the lateral surface 2 from which, during work, must be perfectly applied and energetically fixed a plate 3 such as a plate.
  • This cylinder 1 is provided with two journals or rockets 4 by which it is guided and driven in rotation around its axis 5 by any known means (not shown).
  • the plates are rarely perfect, and the smallest defect in thickness in the plate resulting in a defect in the work provided, touch-ups must frequently be carried out and, for this purpose, it is necessary to be able to place shims 8 under the plate in fixing them directly on the face 2 of the cylinder 1 or on an intermediate sheet.
  • the device for fixing the plate comprises means 10 for perfect application of both the middle part and the ends of the plate, on cylinder 1.
  • These application means 10 comprise, inside the bearing surface of the plate on the cylinder, on the one hand, all along the edges of this surface, a groove 11 housing a seal 12 and , on the other hand, at a short distance from this joint, orifices 13 connected to a circuit 14 for suction of a vacuum pump 15.
  • the orifices 13 open into a peripheral groove 16.
  • a non-return valve 17 is placed on the circuit 14.
  • the grooves 11, 16 can both be carried by the plate or distributed one on the plate, the other on the cylinder but, preferably, they are carried by the cylinder 1, which is hollow and, therefore, interposed between the orifices 13 and the circuit 14, the cavity 18 of the cylinder 1 can be used as a reserve chamber, in particular in the hypothesis mentioned above of stopping the vacuum pump 15.
  • the orifices 13 open into the cavity 18 to which the circuit 14 is connected by means of a rotary joint 19.
  • the circuit 14 is connected to a distributor 20 allowing, with a view to erasing the plate, to bring the chamber 18 to the atmospheric pressure.
  • this means 9 comprises two hubs 21 each engaged on one of the rockets 4 of the cylinder 1 around the axis 5 from which these hubs 21 are free to oscillate at least by a certain angle and, at each of these hubs 21, is, by at least one arm 22 of length adjustable, associated with a support such as a flange 23 capable of grasping by any known means one end of the plate 3.
  • the hubs 21 advantageously carry counterweights 24 which, when the plate is, by elongation arms 3, separated from cylinder 1, balance the load of the assembly formed by the arms, the supports and said plate 3.
  • this assembly will be able to oscillate around the axis 5 of the cylinder 1 and will thus make it possible to drive out the plate 3 of its bearing area on the cylinder 1 for example, to perform touch-up operations there.
  • the adjustable arms 22 consist of jacks supplied with pressurized fluid by a circuit 25 controlled by a distributor 26.
  • each arm 22, consisting of a cylinder, single or double acting, is provided with an elastic element 27, such as a spring, permanently urging the support and therefore the plate towards the cylinder 1 , whereby, even in the event of a break in the fluid supply to the jacks 22, the plate will be applied to the cylinder and the machine can be used, the fluid then being essential only for spreading the plate.
  • an elastic element 27 such as a spring
