Definitions

  • the invention relates to a sheet-fed printing machine in unit construction.
  • the main types are satellite printing presses, tandem printing presses and row printing machines / unit printing machines known (Walenski; Offset printing; Polygraph Verlag Frankfurt / M; 1991; Page 64 ff.).
  • the satellite printing presses have several cylinder groups (offset cylinder / printing form cylinder) a multi-size impression cylinder with a sheet feed and a sheet discharge cooperates, assigned.
  • At least two machines are through Transfer cylinder or a chain system connected in series. Any machine is in five-cylinder design - one impression cylinder, two offset cylinders and two Printing form cylinder - trained and the first machine is with the sheet feeder and the second machine connected to the sheet discharge.
  • the first printing unit is the sheet feeder and the last one Assigned the sheet discharge to the printing unit.
  • An aggregate printing unit is also known (DE 197 14 807 A1), which consists of a Printing cylinder, a transfer cylinder and a plate cylinder with a chamber doctor blade inking system consists.
  • a disadvantage of the inflexibility of the satellite machines is offset by the high degree of compactness.
  • a disadvantage of the unit machines is the large construction space-consuming construction, which is, however, offset by a high degree of variability and an inexpensive manufacturing option.
  • the tandem machines whose design has almost completely disappeared from the market, require a large number of sheet transfers and this design is not variable.
  • CH-A 583 096 is a sheet-fed printing press for offset printing known from at least two printing units.
  • the printing cylinders of the printing units have a triple-sized diameter, with each printing cylinder being assigned two single-size offset cylinders and each offset cylinder being assigned a single-size printing form cylinder.
  • the sheet is transported from printing unit to printing unit via a transfer cylinder. Like the printing cylinders, this has a triple size diameter.
  • a disadvantage of this type of construction is that the triple-sized transfer cylinder makes the printing press long, so that a large installation space is again required for its installation.
  • the object of the invention is to provide a sheet-fed press in unit construction compact design with high variability.
  • the first printing unit 1.1 is connected to a known sheet feeder (not shown) via a plant unit 2. Either a third printing unit, not shown, or a sheet discharge, not shown, is assigned to the second printing unit 1.2.
  • Each printing unit 1 contains two cylinder groups 4 assigned to a printing cylinder 3; 5 or 4; 18 or 18; 21 and a transfer cylinder 8.
  • the impression cylinder 3 and the transfer cylinder 8; 15 are in a substructure 19 and the cylinder groups 4; 5 or 4; 18 or 18; 21 housed in a superstructure 20.
  • the substructure 19 is configured identically for all different superstructures.
  • the cylinder groups 4; 5 are equipped with a printing form cylinder 6 and a downstream offset cylinder 7 which is operatively connected to the printing cylinder 3.
  • An inking unit 13 is assigned to each printing form cylinder 6.
  • a superstructure 20 of a printing unit 1.1 or 1.2 is equipped with a first cylinder group 4 and a flexographic printing cylinder group 18, the flexographic printing cylinder group 18 consisting of a plate cylinder 17 with a chambered doctor blade inking system 16 or each superstructure 20 with two flexographic printing cylinder groups 18; 21 equipped.
  • the two cylinder groups 4; 5 or 18; 21 are arranged in mirror image with respect to a mirror plane 14; the mirror plane is arranged vertically or almost vertically.
  • the printing form cylinder 6, the offset cylinder 7 and the plate cylinder 17 are simply large; relative to the printing form cylinder 6, the printing cylinder 3 is three times the size or larger, the size of the transfer cylinder 8 is double the size.
  • the transfer cylinder 8 can also be designed as a generally known turning cylinder 15.
