Definitions

  • the description relates to a pressure cylinder with a metal cylinder core, on which a carbon fiber-containing sleeve is arranged.
  • the print length is due to the effective diameter of the printing cylinder carrying the clichés. So not for everyone you want Print length of a special cylinder with the associated bearing structures needed, it is known on the peripheral surface of the cylinder core to postpone a replaceable sleeve called a sleeve then the effective diameter and thus the print length is determined.
  • EP-A-0 732 201 describes a printing cylinder of this type in which the Sleeve has a multilayer structure. Two layers from one through Carbon fiber reinforced composite material form an intermediate space with Plastic is foamed. The inner surface of the sleeve lies well on the peripheral surface of the steel core, so that during the printing process occurring relatively high radial forces due to the relatively soft Foam layer of the sleeve through on the rigid cylinder core can be transferred.
  • a disadvantage of this construction is that with the help of the sleeve only a limited increase in print length is achieved because larger ones Print lengths, the layer thickness of the sleeve would be so great that the necessary stiffness and dimensional accuracy of the outer surface of the sleeve is no longer guaranteed could be.
  • Another disadvantage is that the replacement of the sleeve is relatively labor-intensive, since the sleeve covers the entire surface rests on the cylinder core and thus when pushed on or pulled off high friction forces have to be overcome. To reduce these frictional forces it is known to introduce compressed air into the interior of the cylinder core, the via radial openings in the space between the cylinder core and Sleeve enters.
  • EP-A-0 769 373 describes a pressure cylinder in which the sleeve, the the print length determines, at both axial ends stub axle with a smaller one Has diameter and is stored directly in the machine frame.
  • a yourself steel shaft extending through the sleeve spaced from the sleeve is only used to remove the sleeve when changing the sleeve Raise bearings and hold them so that they are axially withdrawn from the shaft can be.
  • the object of the invention is to provide a pressure cylinder in which the Print length can be varied over a wide range by changing the sleeve can without affecting the print quality.
  • this object is mentioned in the case of a pressure cylinder of the input Art solved in that the sleeve is self-supporting and through in the area disks arranged at both ends at a distance from the circumferential surface of the cylinder core is held.
  • the term "self-supporting" in this context means that the sleeve has such a high degree of inherent rigidity that, although only at the ends is supported by the disks on the cylinder core, those that occur during printing Can withstand radial forces, so that occurring in the sleeve Deformations remain within the permissible tolerance limits. It has shown, that this property of the sleeve through the use of a carbon fiber existing or reinforced by carbon fiber material can. Because of the relatively low specific weight of such a material the total weight and moment of inertia of the sleeve remain relative low, which is beneficial to the smooth running of the press and to the Manageability affects the sleeve or the entire printing cylinder.
  • the effective diameter of the sleeve not like conventional sleeves alone determined by the layer thickness of the sleeves, but it is largely determined by determines the distance between the sleeve and the cylinder core. This allows the Use of sleeves with relatively large diameters, so that accordingly large print lengths can be achieved.
  • Another advantage of the invention is that the sleeve is essential can be removed more easily from the cylinder core, since they are only arranged at the ends Disks is supported on the cylinder core, so that only relatively small Frictional forces occur.
  • the two disks can be made from a different material from the sleeve Material, for example made of steel or aluminum. You can however, optionally also consist of the same material as the sleeve or even be formed in one piece with the sleeve. It is also possible to form these washers bearing pins with which the sleeve directly in the machine frame is stored.
  • the cylinder core is preferably also one without the Sleeve insertable pressure cylinder.
  • the impression cylinder can be opened a minimum print length can be set by simply omitting the sleeve becomes.
  • the clichés can then be arranged on a conventional sleeve be pushed onto the impression cylinder, but you can choose can also be clamped directly onto the circumferential surface of the cylinder core.
  • the cylinder core preferably has a compressed air line in a manner known per se lead from the radial openings to the peripheral surface.
  • a compressed air line in a manner known per se lead from the radial openings to the peripheral surface.
  • the printing cylinder shown in Fig. 1 has a cylinder core 10, which is preferably is formed by a conventional steel pressure cylinder and is provided at both ends with stub axles 12, the storage in enable a machine frame, not shown. Furthermore, the cylinder core 10, as is known per se in the case of pressure cylinders, an axial bore 14 on which compressed air can be supplied, which then has radial openings 16 can emerge from the peripheral surface 18 of the cylinder core.
  • the cylinder core 10 is surrounded at a distance by a cylindrical sleeve 20, which is formed by a tubular body made of carbon fiber composite material becomes.
  • a tubular body made of carbon fiber composite material and so far for example as web guide rollers in printing machines or, if necessary also used as a printing cylinder for shorter printing lengths.
  • this tubular body is a scaffold made of diagonally wound carbon fibers, which a matrix of plastic are embedded.
  • the sleeve 20 is at both ends by flat washers 22 made of steel or aluminum completed and is supported only by these discs on the cylinder core 10 from.
  • the disks 22 are non-rotatably connected to the cylinder core 10, as symbolized in the drawing by wedges 24.
  • the sleeve 20 rotatably connected to the disks 22, so that the cylinder core 10 and the sleeve 20 together a rigid, bending and torsional stiffness Form the pressure cylinder.
  • Clichés not shown, can be on the outer peripheral surface the sleeve 20 are clamped.
  • the sleeve 20 however, a conventional sleeve can also be pushed on, which in turn is then carries the clichés.
  • For easier replacement of such a sleeve also has the sleeve 20 openings 26 with which those from the openings 16 of the cylinder core escaping compressed air to the peripheral surface of the sleeve can be forwarded.
  • the dimensions of the impression cylinder can vary within a wide range.
  • the outer diameter of the impression cylinder can be expanded widely Change area. Due to the relatively small wall thickness of the sleeve 20 and the low specific weight of this sleeve also increases with large ones Outside diameter, the total weight and the moment of inertia of the Printing cylinder not significantly.
  • the working width of the impression cylinder is about 800 to 2000 mm
  • the diameter of the cylinder core 10 about 10 mm, corresponding to a minimum print length of the order of magnitude of just over 30 mm
  • the outer diameter of the sleeve 20 is, for example up to 400 mm.
  • the wall thickness of the sleeve 20 is of the order of magnitude from about 15 to 20 mm. Because of the carbon fiber reinforced material this wall thickness sufficient to the required inherent rigidity of the sleeve 20 guarantee. Those that act on the outer surface of the sleeve when printing Radial forces are introduced into the two disks 22 without the Sleeve 20 deformed significantly. Because the force transmission in the cylinder core 10 in the vicinity of the stub axle 12 is also a training of the cylinder core 10 largely avoided. In addition, the bending stiffness of the printing cylinder increased overall by the shell-shaped structure.
  • the disks 22 are flush with the ends of the sleeve 20, 2 shows an embodiment in which the disks 22 face each other the sleeve are slightly indented.
  • the discs 22 will have a better distribution of the support forces on the Length of the sleeve 20 and thus a significant reduction in printing reached bending moments acting on the sleeve 20.
  • they are bending moments acting on the cylinder core 10 slightly increased, but lift these effects do not affect each other, but the end result will be higher Bending rigidity of the impression cylinder reached.
