Definitions

  • the invention relates to a web-fed offset printing press with a plurality of printing units arranged one behind the other; in each of which a printing material web can be coated with ink on both sides and a printing unit for flying plate changes, in which one plate cylinder and blanket cylinder pair can be stopped for the plate change and the other can be turned on a common rotating impression cylinder.
  • an offset rotary printing press in which a plurality of printing units are arranged one behind the other, a printing material web in each of the printing units being able to be coated with a color on both sides.
  • the first printing unit a so-called single-printing unit, comprises a double-large common impression cylinder, to each of which a pair of blanket-plate cylinders is attached, while the other pair of blanket-plate cylinders can be prepared for the plate change.
  • This known printing machine has the disadvantage that a separate printing unit is required for the single-printing unit with a flying plate change.
  • Fig. 1 shows the cylinder arrangement of the first printing unit in a web offset rotary printing press which has a plurality of printing units for face and back printing, which are arranged one behind the other.
  • the printing unit shown comprises a first pair of cylinders, consisting of a plate cylinder 1 and a blanket cylinder 2, and a second pair of cylinders, consisting of a plate cylinder 3 and a blanket cylinder 4.
  • a printing material web 5 between the blanket cylinders 2 and 4 is usually printed on both sides, d. H. provided with a perfecting.
  • the main drive for the cylinders 1 to 4 is fed in the printing unit in the printing unit from a gear 7, a bevel gear 6 which, like the other gears used, is preferably helically toothed.
  • the gear wheel 6 is seated on a shaft 8 (FIG. 3) on which two clutches 9, 10 are further arranged.
  • the shaft 8 is aligned with the axis of a common impression cylinder 11 for the blanket cylinders 2, 4 or is identical to this.
  • Two gearwheels 11 ′, 11 ′′ are arranged on the shaft 8, and can optionally be fixedly connected to the drive shaft 8 by means of the couplings 9, 10.
  • FIG. 2 shows the drive wheel train of the cylinders 1 to 4 on one machine side from the main drive the drive by actuating the clutch 9 in such a way that the gear 11 'is driven by the bevel gear 6.
  • the gear 11' meshes with the gear 2 'on the axis of the rubber blanket cylinder 2.
  • This gear arranged on the axis of the rubber blanket cylinder 2 'then directs the drive directly to the meshing drive wheel 1' of the plate cylinder 1 and the meshing gear 4 'of the blanket cylinder 4.
  • the double-wide gear 3' of the plate cylinder 3 also meshes with the gear 4 ', so that the Cylinders 1 to 4 can be driven by the main drive in the straight-printing reverse pressure operation shown in Fig. 1.
  • the drive therefore takes place from B to A1 and A3 and from B to A2 according to Fig. 1.
  • the impression cylinder 11 serves as a paper guide roller for the web 5 to be printed during normal perfecting and counter-printing operations. In this operating mode, it is also possible to slightly turn off the impression cylinder 11 serving as the paper guide roller from the blanket cylinder 2. It is separated from the blanket cylinder 4 anyway. Conventional conventional eccentrics, which are indicated in FIGS. 1 and 4 but not described in more detail, can be used for this. The impression cylinder 11 is also separated from the blanket cylinder 4.
  • the printing unit in addition to the operating mode shown in FIG. 1, can also be used as a single-printing unit with a flying plate change.
  • This is indicated schematically in FIG. 4.
  • the print carrier web 5 is not passed between the two blanket cylinders 2 and 4, but rather around the impression cylinder 11.
  • the main drive is introduced via the impression cylinder 11 or via the gearwheels 11 ′ or 11 ′′ arranged on it.
  • 4 is to be released with the help of the clutches 9 and 10 either the gear 11 'or the gear 11 "from the drive shaft 8.
  • the bevel gear 6, ie the main drive 7, 8 only the gears 2', 1 'and thus the cylinders 2 and 1 or the gears 11 ", 4 'and 3' and thus the cylinders 4 and 3 driven.
  • the non-driven plate cylinder 1 or 3 with the associated blanket cylinder can be stopped for a plate change.
  • the cylinder for example 1
  • the cylinder is accelerated from the auxiliary drive 12 via a bevel gear 14, a clutch 16 and a further bevel gear 18 to the speed of the main drive and is synchronized with it.
  • the coupling 15 separates the auxiliary drive 12 from the lower plate cylinder 3.
  • a corresponding conventional electronic circuit ensures that the auxiliary drive 12 is connected to the plate cylinder 1 or the plate cylinder 3 either after corresponding preparatory work.
  • the cylinders 1 and 2 can then be connected to the impression cylinder 11, i. H. the blanket cylinder 2 is turned on the impression cylinder 1 by actuating the eccentric.
  • the main drive 6, 7 is separated from the cylinder pair 3 and 4 and in turn the gear 4 'is displaced and, after a corresponding plate change on the plate cylinder 3, the auxiliary drive via a bevel gear 13 of the clutch 15 and a bevel gear 17 of the plate cylinder 3 and thus the blanket cylinder 4 is accelerated and synchronized to the operating speed, after which the adjustment to the impression cylinder 11 takes place in the same way. 2, the drive takes place via B1 and C1 or B2 and C2.
