Definitions

  • the invention relates to a web-fed rotary offset printing machine with a printing unit for flying plate changes, in which one plate cylinder / blanket cylinder pair can be stopped for the plate change and the other can be turned on a common rotating impression cylinder, with the impression cylinder as the paper guide roller for the intermediate between the printing and reverse printing operation the track guided by the blanket cylinders can be used and gear wheels are positioned on the axis of the impression cylinder, which selectively connect the main drive to one of the two rubber cylinder drive wheels via a first or second clutch.
  • Figures 1 and 2 show a printing unit consisting of five cylinders in which a print carrier web 1 optionally on both sides, i.e. can be provided with a perfect and reverse print (Fig.1) or from one side with a double face print (Fig.2), as indicated. If the print carrier web 1 is only provided with a face print, the printing unit shown can work in the so-called "flying plate change", in which, as is known, a pair of blanket cylinders / plate cylinders can be stopped for each plate change, while the other pair of blanket cylinders / plate cylinders can be used to apply a face print is used.
  • the printing unit comprises two rubber cylinders 2, 3, against which one of the plate cylinders 4, 5 can be adjusted.
  • the print carrier web 1 is provided with a face and an impression, the printing between the two rubber cylinders 2, 3 and the impression cylinder 6, if desired, acting as a paper guide roller.
  • the impression cylinder 6 can be placed on the upper rubber cylinder 2 or can be turned off slightly. 2, double printing is applied to one side of the print carrier web 1, the common impression cylinder being set against both the blanket cylinder 2 and the blanket cylinder 3, and the blanket cylinders 2, 3 must be spaced apart.
  • the cylinders 2 to 6 shown each have pits 7 to 11, each of which must have a specific position with respect to adjacent cylinders in the different operating modes. If the operating mode according to FIG. 1 is used in perfecting, the pit 8 of the blanket cylinder 3 must face the pit 7 of the blanket cylinder 2. When changing to production according to FIG. 2, the lower rubber cylinder 3 must be rotated so that its pit 8 faces the pit 11 of the impression cylinder 6.
  • Figures 3 and 4 show the cylinders 2 to 6, on the respective shafts or stub shafts 13 to 17 corresponding gears are positioned.
  • the main drive from a gearwheel 18 arrives at a gearwheel 19 which is arranged in a rotationally fixed manner on the shaft 17 of the impression cylinder 6.
  • Another gearwheel 20 is positioned on the same shaft 17 and can optionally be connected to the shaft 17 with the aid of a coupling 21.
  • a gear 22 meshes with the gear 20, which is arranged on the shaft 13 of the upper rubber cylinder 2, and a gear 23 meshes with the gear 22 on the shaft 15 of the upper plate cylinder 4.
  • the common counter-pressure cylinder 6 can thus and the upper pair of rubber cylinders / plate cylinders 2, 4 are driven, while the lower pair of cylinders 3, 5 can be stopped for a plate change when the cylinders are turned off.
  • a further gear wheel 24 is arranged, which can optionally be connected to the shaft 17 of the counter-pressure cylinder 6 by actuating a clutch 25.
  • the gear 24 meshes with a preferably double-wide gear 26 on the shaft 14 of the rubber cylinder 3 in the exemplary embodiment.
  • a gear 27 meshes with the double-wide gear 26, which is arranged on the shaft 16 of the lower plate cylinder 5. If the clutch 25 is activated instead of the clutch 21, the lower pair of blanket cylinders / plate cylinders 3, 5 can be driven together with the impression cylinder 6, while the upper one when the clutch 21 is released Rubber cylinder / plate cylinder pair 2, 4 can be stopped for a plate change.
  • a further gearwheel 28 is positioned on the shaft of a rubber cylinder, for example on the shaft 13 of the upper rubber cylinder 2, which gear wheel can optionally be coupled to the shaft 13 of the rubber cylinder 2 with the aid of a third clutch.
  • the gear 28 always meshes directly or indirectly with the gear 26 with which the gear 24 also meshes.
  • the gear 26 is therefore preferably double width.
  • the printing unit according to the invention is to operate in the perfecting mode, in which the print carrier web 1 according to FIG. 1 is passed between the two rubber cylinders 2, 3, the impression cylinder 6 serving only as a paper guide roller, then the third clutch 29 and in the exemplary embodiment the Clutch 21 are activated while the clutch 25 is released. As a result, the drive comes from the gearwheels 18, 19, 20, 22, 28 to the double-width gearwheel 26 and the gearwheels 27 and 23. Thus, all cylinders 2 to 6 are driven, but reversing the direction of rotation for the lower one in the exemplary embodiment in accordance with the invention Cylinder pair 3, 5 was reached.
  • the gears used can always remain in engagement in all operating modes. This means that no significant profile shift is required. It is understood that using the principle underlying the invention, the drive for the double Fine pressure and for the plate change can also be varied, with corresponding, in individual cases desired arrangements of the clutches and gears on other sides of the cylinders 2 to 6 also being possible.
  • the gears 24, 26, 28 can mesh directly with one another, as in the exemplary embodiment. However, it is also possible, particularly in the case of correspondingly large machines, to arrange further gears or pairs of gears between them, so that the gears are indirectly meshed with one another.

Claims (2)

  1. Rotative offset comportant une unité d'impression permettant un changement de plaques en marche, dans laquelle un couple (4,2;5,3) cylindre porte-plaque/cylindre porte-blanchet peut être arrêté pour le changement des plaques et l'autre couple de cylindres peut être serré contre un cylindre rotatif commun de contre-pression, et dans laquelle, dans le cas du fonctionnement à retiration, le cylindre de contre-pression (6) peut être utilisé en tant que cylindre guide-papier pour la bande guidée entre les cylindres porte-blanchet (2,3) et que sur l'axe (17) du cylindre de contre-pression sont positionnés des pignons (20,24), qui, par l'intermédiaire d'un premier ou d'un second accouplement (21,25), relient le dispositif d'entraînement principal (18,19) au choix à l'un des deux pignons (22,26) d'entraînement des cylindres porte-blanchet,
