Definitions

  • the invention relates to a printing unit of a web-fed rotary printing press according to the preamble of claim 1.
  • Printing units of web-fed rotary printing presses usually have a plurality of printing units, each printing unit comprising at least one transfer cylinder, a forme cylinder and an inking unit, and preferably a dampening unit.
  • printing units without dampening There are also printing units without dampening known.
  • counter-pressure cylinder which are also referred to as a satellite cylinder, have, wherein such an impression cylinder can interact with one or more transfer cylinders of different printing units.
  • printing units are also known which do not have counter-pressure cylinders, with such printing units without counterpressure cylinders unrolling the transfer cylinders of two printing couples.
  • the transfer cylinders are also referred to as rubber cylinders and the form cylinder as a plate cylinder.
  • the form cylinder or plate cylinder carry printing forms.
  • the present invention is based on the problem to provide a novel printing unit of a web-fed rotary printing press. This problem is solved by a printing unit according to claim 1.
  • motor-driven ductor rollers of the inking units are mounted on separate side walls together with an ink fountain and a film roller of the inking units such that in the area of each printing unit the ductor roller, the ink fountain and the film roller of the respective inking unit relative to the cylinders and rollers coupled on the drive side via a gear train Printing units are displaced to release access to the drive train coupled via a gear train cylinders and rollers of the printing units.
  • a printing unit of a web-fed rotary printing press is divided into modules such that on the one hand all via a gear train drive side coupled cylinder and rollers are mounted on sidewalls of the printing unit in the form of a first module together, and that on the other hand, ductor rollers of the inking units together with an ink fountain and a film roller of the inking units are mounted on separate side walls as second modules, so that in the region of each inking unit of a printing unit the ductor roller, the ink fountain and the film roller can be displaced relative to the drive train coupled via a gear train cylinders and rollers of the printing units.
  • Fig. 1 shows a schematic section of a web-fed rotary printing press in the region of a printing tower 10, which is formed from two superimposed positioned, printing units 11 according to the invention.
  • Each of the two printing units 11 each comprise four printing units 12, wherein each of the printing units 12 comprises a transfer cylinder 13, a forme cylinder 14, an inking unit 15 and a dampening unit 16.
  • the transfer cylinders 13 of each two horizontally juxtaposed printing units 12 roll off to form printing areas for a printing material to be printed.
  • the printing units 11 are 8-cylinder printing units.
  • the printing units 11 are separated into modules, wherein the nature of the separation of the printing unit in modules constitutes the core of the present invention.
  • the printing unit 11 comprises a first module which comprises all cylinders and rollers coupled on the drive side via gears or a gear train, ie the transfer cylinders 13, the forme cylinders 14 and all rollers of the inking unit 15 to be driven by the transfer cylinder 13 and / or forme cylinder 14 Dampening units 16.
  • This module may also include rollers driven by friction via cylinders or rollers driven by the gear trains.
  • Eigenmotorisch driven ductor rollers 18, ink boxes 19 and film rollers 20 of the inking units 15 are mounted on separate side walls and form independent modules, in such a way that in the area of each printing unit 12, the ductor roller 18, the ink fountain 19 and the film roller 20 of the respective inking unit 15 relative to the drive cylinders coupled via a gear train cylinders and rollers of the printing units are displaced, according to Fig. 1 in a direction which is perpendicular to the longitudinal center axis of the transfer cylinder 13 and the forme cylinder 14. This will, as in the right side of Fig.
  • the modules with the ductor rollers 18, ink ducts 19 and film rollers 20 may further comprise the same friction driven rollers.
  • the modules which comprise the ductor rollers 18, the ink ducts 19 and the film rollers 20 may also be displaceable in a direction which runs parallel to the longitudinal central axis of the transfer cylinders 13 and forme cylinders 14.
  • Fig. 1 In the illustrated embodiment of the Fig. 1 are in the range of each printing unit 11, the ductor rollers 18, ink boxes 19 and film rollers 20 of two superimposed printing units 12 each jointly displaceable. Likewise, it is possible that if, how Fig. 1 shows two printing units 11 are positioned vertically to one another to a printing tower 10, the ductor rollers 18, ink boxes 19 and film rollers 20 of the four printing units positioned one above the other are jointly displaceable.
  • the invention is not limited to printing machines with eight-cylinder rubber-rubber arrangement, but also extends to satellite arrangements.
