Definitions

  • the printing cylinders of printing machines may, in some cases, consist of a removable sleeve which is fixed on a bearing shaft.
  • Such an arrangement has many advantages and in particular that of allowing the user, by a simple exchange of the sleeve, to vary as desired the print format. It has been proposed to ensure the attachment of the sleeve on the carrier cylinder to play on the deformation of the sleeve under the effect for example of a pressurized air circuit, or on that of the carrier shaft by expanding it during of use under the effect of oil pressure.
  • the means delivering a clamping force and / or loosening may consist of energy storage means such as for example at least one resilient element in the compressed state when in the working position, including a spring or a spring ring.
  • the pressing element may consist of a block formed for example of at least one connecting washer.
  • the sleeve will bear against a shoulder of the carrier shaft, so as to ensure the indexing in translation of these two elements. Furthermore their indexing in rotation will be provided by a connecting element such as for example a pin or a key.
  • the control shaft may comprise a frustoconical portion, and the wall of the carrier shaft will be traversed by at least one radial housing in which a ball will be arranged, so that a longitudinal displacement of the control shaft in one direction applies this ball against the sleeve so as to secure it to the carrier shaft and that a longitudinal displacement of the control shaft in the other direction does not apply this ball against the sleeve so as to separate it from the carrier shaft.
  • FIG. 1 is a longitudinal sectional view of a printing cylinder according to FIG. invention shown in position of assembly / disassembly of its sleeve
  • Figure 2 is a longitudinal sectional view of the printing cylinder shown in Figure 1 in the working position
  • Figure 3 is an enlarged partial sectional view showing a detail of embodiment of the clamping means of the sleeve on its carrier shaft
  • Figure 3a is a perspective view of an assembly washer used in the clamping blocks implemented according to the invention
  • Figure 3b is a diametral sectional view along the line III-III of Figure 3a of the assembly washer shown thereon
  • Figure 4 is a longitudinal sectional view of a second embodiment of a printing cylinder according to the invention r represented in working position
  • Figure 5 is a longitudinal sectional view of a third embodiment of a printing cylinder according to the invention shown in the working position
  • Figure 6 is a partial longitudinal sectional view of of
  • FIGS. 1 to 3 show a printing cylinder 1 which can be, for example, depending on the use, a plate cylinder, a blanket cylinder in the case of offset printing, a cylinder which is stamped in the case of a flexo printing or an engraved cylinder in the case of a heliographic printing.
  • a printing cylinder 1 which can be, for example, depending on the use, a plate cylinder, a blanket cylinder in the case of offset printing, a cylinder which is stamped in the case of a flexo printing or an engraved cylinder in the case of a heliographic printing.
  • This printing cylinder 1 essentially consists of a carrier shaft 3 on which is releasably attached a sleeve 5.
  • the sleeve 5 consists of a tubular element of strong Steel thickness, coming to slip on the carrier shaft 3, so that its stiffened area extends over its entire length.
  • the carrier shaft consists of a cylindrical element terminating at each of its ends by a portion 3a of smaller diameter on which are disposed two bearings respectively 7 and 7 ', the left part in the figure comprising a drive gear 8.
  • the carrier shaft 3 is pierced, throughout its length, a central and longitudinal housing 9 inside which is slidably mounted a control shaft 11.
  • the bearing shaft 3 On one of its sides, left on the Figures 1 and 2, the bearing shaft 3 is provided with a cylindrical shoulder 13 against which, in the working position, one of the transverse faces 5a of the sleeve 5 is held in abutment.
  • the displacement of the transmission rings 17 is ensured by transverse pins 19 which pass through the rings 17, the carrier shaft 3 and the control shaft 11.
  • the pins 19 are fitted into the control shaft 11 and there is provided a clearance between said pins 19 and the transverse orifices made in the carrier shaft 3, so that when the control shaft 11 is moved longitudinally in its housing 9 inside the carrier shaft 3, the transmission rings 17 so as to ensure either the compression of the connecting washers 15, when it is desired to ensure the clamping of the sleeve 5 on the carrier shaft 3, or the debridement of these washers 15 when it is desired to ensure the release of the sleeve 5 relative to the carrier shaft 3.
  • the energy required for the application of the transmission rings 17 on the connecting washers 15 is provided by elastic compression washers 21 which are arranged between the shoulder 13 and a cylindrical ring 22 threaded onto the portion 3a of the carrier shaft 3, this ring 22 being immobilized in translation by a transverse pin 23 passing therethrough and the carrier 3 and control shaft 11.
  • the positioning of the ring 22 with respect to the shoulder 13 is such that said ring 22 assures a compression of the elastic compression washers 21 such that the energy stored by them during this compression is greater than the force that the transmission rings 17 must transmit to ensure the crushing of the connecting washers 15.
  • the printing cylinder 1 consists of a carrier shaft 3 and a sleeve 5 which is slidably fitted thereon.
  • This sleeve is hollowed at both ends of a cylindrical housing in which is housed a stiffness ring formed in this case by a bearing ring 24, so that the sleeve 5 is supported on the carrier shaft 3 by the inner surface of the latter.
  • the carrier shaft 3 is traversed by a central and longitudinal housing 9 in which is slidably mounted a control shaft 11 which comprises, at the right of the bearing rings 24, a frustoconical portion 27.
  • the wall of the carrier shaft 3 is pierced with a plurality of radial housings 28 which receive balls 30 of diameter d greater than the thickness e of said wall.
  • the energy required for securing the sleeve 5 and the shaft 3 is provided by a compression spring 32 which is arranged between two cups, one formed by a recessed chamber. at the end of the control shaft 11 and the other in an extension member 3 'of the carrier shaft 3 which is fixed at the end of the latter by fastening means not shown in the drawing.
  • the stiffness of the compression spring 32 will be determined so that, in the compression state in which it is when the impression cylinder 1 is in the working position, the energy it delivers is sufficient for the force clamping action exerted by the balls 30 on the sleeve 5 ensures a correct drive of the latter.
  • the energy source is provided by a hydraulic cylinder 51 whose piston 52 comprises a cage 53 at its active end ensuring the maintenance of a bearing 54 whose inner portion is integral with the end of the control shaft 11.
  • the jack exerts a force F on the control member 11, having the effect of applying, by means of the pins 19, the transmission rings 17 on the connecting washers 15 constituting the pressing element.
  • an opposite direction force F ' is exerted with the cylinder 51, which has the effect of moving the transmission rings 17 away from the assembly washers 15 so as to no longer compress them, thus freeing the sleeve of its carrier shaft 3.
