Definitions

  • the invention relates to a device for applying a sleeve to a cylinder, in particular a serving as a printing form or rubber-coated sleeve on the cylinder of an offset rotary printing press, with an auxiliary device which feeds the sleeve through an opening in the printing unit side wall, axially parallel to the cylinder, before the release of the Axle journal bearing in this side wall supports the cylinder with a bracket, after which the sleeve can be pushed onto the cylinder via the axle journal bearing.
  • Such a device is known from DE-PS 470 937 for a rotogravure printing machine.
  • a carrier arranged in the printing unit side wall and grasping the journal bearing is lowered in the plane of the printing unit side wall after the cylinder has previously been gripped by an auxiliary device that supplies the sleeve parallel to the axis of the printing unit cylinder, i.e. was supported.
  • This allows the sleeve to be pushed onto the gravure cylinder via the journal bearing.
  • the carrier is then raised again against the journal bearing and the auxiliary device is removed.
  • rotogravure cylinders of this type do not have to be pivoted so that they can be stored in a stationary manner in the two printing unit side walls.
  • the print carrier web can be printed in the usual way by means of rollers, so-called impression rollers, which can be adjusted to the gravure cylinders. If, for example, sleeves of this type are to be applied to printing couple cylinders which are adjustable for engagement with other adjacent printing couple cylinders, i.e. Usually have to be stored eccentrically, safe application with this known device is not indicated.
  • a cylinder for example a so-called offset cylinder 3 with a rubber coating, is mounted between two printing unit side walls 1, 2 via its axle journals 4, 5.
  • Such cylinders have to be used against other cylinders, e.g. be mounted on a plate cylinder and / or on an impression cylinder so as to be displaceable or pivotable, which is why eccentrics 11, 12 which can be rotated in the circumferential direction on bearings 4, 5 via bearings 8, 9 are used, which in turn are provided in side wall openings provided in printing unit side walls 1, 2 6, 7 are positioned.
  • a drive gear 10 which is usually helically toothed, is mounted on the elongated axle journal 4 which projects beyond the printing unit side wall 2.
  • only one eccentric is shown, but it goes without saying that two eccentrics lying one above the other can also be used within the scope of the invention for corresponding adjustment or movement possibilities.
  • a printing unit side wall here the printing unit side wall 1
  • a side wall opening 7 whose diameter dw is greater than the diameter D of the printing unit cylinder 3
  • the diameter dL being arranged on the bearings, here the bearing 9 Bushing or eccentric 11 is smaller than the diameter D of the printing unit cylinder.
  • the printing unit side wall 2 can be made in a known manner, but partial features of the invention can also be used here, as will be described below.
  • a jaw chuck 13 is provided in or on the side wall 1, which must have at least two jaws.
  • a three-jaw chuck is useful.
  • the jaw chuck 13 can be displaced in the opposite direction in the direction of the double arrow 14 in the plane of the printing unit side wall 1 in order to enable the sleeve 15 indicated in FIG. 2 to be applied through the wall opening 7. If a sleeve is applied to the plate cylinder of an offset rotary printing machine or to the form cylinder of a flexographic or high-pressure machine, this is entered by e.g. chemical treatment generated print image. If the sleeve 15, as shown in FIGS. 1, 2, is applied to a blanket cylinder (offset cylinder) of an offset rotary printing press, it is provided with a rubber layer, which can be vulcanized on, for example.
  • an auxiliary device 16 Before the sleeve 15 is slid onto the cylinder 3, an auxiliary device 16 must be attached from the side to the printing unit side wall, which can be moved up, for example, by means of wheels that are not specified.
  • This carries on a cylindrical support 17 to be pushed onto the cylinder 3 sleeve 15.
  • a holder 18 On this a holder 18 is arranged, which in the simplest case can consist of a tip which engages in a corresponding recess 19 on the pin 5 to the cylinder during the sliding process 3 on the lin to keep one side. Then the jaw chuck 13 can be moved apart so that the sleeve 15 can be pushed onto the cylinder 3 through the side wall opening 7.
  • the carrier 17 and the sleeve 15 are shown somewhat shorter in FIG. 2.
  • a sleeve or eccentric 12 arranged on the bearing 9 is fixed in the circumferential direction, in a circumferential position which is set for the desired axial position or the required center-to-center distance from one or more adjacent cylinders to be able to slide on the sleeve 15.
  • the circumferential fixation of the eccentric 12 shown there can be achieved in that the eccentric 12 before the jaw chuck 13 is moved apart by a mechanical or magnetic or other holding or fixing device, which possibly allows a change in length, with the printing unit side wall 1 or with the Jaw chuck 13 is connected.
  • Such locking, indicated at 57 can take place, for example, by means of a disc brake or with the aid of electromagnetic devices.
  • the locking or circumferential fixation of the eccentric 12 ensures that the center-to-center distance of the cylinder 3 is maintained during the pushing-on process to other cylinders.
  • the auxiliary device 16 can be moved back again after the jaw chuck 13 has been moved together again and the locking mechanism 57 has been released. It is expedient for the slight expansion of the sleeve 15, for example by means of compressed air flowing out of the cylinder jacket of the cylinder 3, to facilitate the sliding-on process.
  • a support 20 can also be used, which can be placed approximately in the middle of the cylinder 3 in the direction of arrow 21 in the cylinder 3 in order to support it at the beginning of the pushing-on process until the sleeve 15 has been pushed on far enough. If the auxiliary device 16 is long enough, however, the support 20 may be dispensed with.
  • An impression cylinder 22 and a plate cylinder 23 are assigned to the cylinder 3 used as the offset cylinder. Due to the eccentric mounting of the cylinder 3, the latter can be placed at least on the plate cylinder 23 and possibly also on the impression cylinder 22. However, the counter-pressure cylinder 21 can also be moved to the cylinder 3 by means of a corresponding eccentric bearing in order to print on a print carrier web 24 passing between them.
  • An annular extension 35 is provided on the pin 25, on which the locking or blocking device is positioned in the form of a clutch or a brake 36 which acts against the inner bore of the eccentric, i.e. that when activated, there is a circumferential blocking of the eccentric 33 on the journal 25.
  • This blocking takes place in accordance with the preceding statements within the scope of the invention in each case before the axle journal bearing is released, i.e. before the jaws 27, 28 move apart as shown in FIG. 4.
  • the jaws 27 and 28 for the cylinder 3 and the jaws 29, 30 for the plate cylinder 23 can be displaced in opposite directions by having 7 toothings on them and on the side wall opening 37, 37 'and 38, 38' are attached, in each of which a toothed drive, for example spur gears 40, 41, 42, 43, engage.
  • a toothed drive for example spur gears 40, 41, 42, 43
  • the opposing displacement of the jaws 27 to 30 is possible. It may be expedient to separate the adjacent upper jaw areas by a gap, as indicated at 39.
  • Appropriate means are provided for adjusting the eccentric bushes 33 and 50, which, as indicated at 46 and 47, can be motors which engage with the eccentrics 33, 50 via a toothing, so that the required starting and stopping processes are carried out can be.
  • this eccentric adjustment 46 which are arranged on the jaws 28, are moved apart, which is advantageous.
  • the plate cylinder is positioned according to FIG. 5 via its axle journals 51, 54 via bearings 52, 55 in bushes 53, 56, the bush 56 being arranged in the jaws 29, so that the application of a sleeve to the plate cylinder is also carried out in the manner described above 23 can be done.
  • the cylinders 3, 23 are driven in a conventional manner via gearwheels, the toothed rim arranged on the journal 48 being designated 59.
  • eccentrics 12 are fixed circumferentially on the printing unit side wall 1 or on the jaw chuck 13 which can be moved apart, they should have a two-part or multi-part construction.
  • a further advantageous, extensive fixing of the eccentrics (e.g. 12) is possible in that a blocking 60, e.g. in the form of a tip or brake, which is provided when starting, i.e. Attaching the auxiliary device 16 holds the eccentric 12 as positively as possible.
