Definitions

  • the invention relates to a printing unit of a web-fed rotary printing press according to the preamble of patent claim 1.
  • Printing units of web-fed rotary printing presses have a plurality of printing units, wherein each printing group at least consists of a transfer cylinder, a forme cylinder and an inking unit, and preferably a dampening unit.
  • printing units without dampening can have impression cylinders, wherein 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.
  • Printing units of web-fed rotary printing presses are increasingly compact, that is, designed with smaller dimensions.
  • the available space at the printing units of a Duckmaschine that is available for positioning or arrangement of the inking and dampening units space is reduced.
  • Direction of the cylinders of the printing units runs. From the EP 0 638 419 B1 a printing unit of a web-fed rotary printing press is known, in which the inking units and dampening units are combined into modular units, which are arranged above or below the printing units and can be moved in the axial direction of the cylinders of the printing units.
  • rail-bound or roll-bound transport devices are used which, on the one hand, always specify a fixed transport direction and which on the other hand complicate the structural design of the web-fed rotary printing press and thus cause higher costs.
  • the present invention is based on the problem to provide a novel printing unit of a web-fed rotary printing press, which on the one hand has a compact design with good access to the cylinders and on the other hand a simple structural design.
  • each inking module of the printing unit can be moved relative to the other components of the printing unit by means of an air cushion transport device.
  • Fig. 1 and 2 show a section of a web-fed rotary printing press in the range of two vertically stacked, inventive printing units 10, 11, which together form a printing tower.
  • each of the printing units 10, 11 has four printing units 12 for printing on a web-shaped printing material 13, which is transported in the vertical direction by the printing units 10, 11.
  • Each of the printing units 12 has a forme cylinder 14, a transfer cylinder 15, an inking unit 16 and a dampening unit 17, wherein each two transfer cylinders 15 from 12 to different sides of the printing units 10, 11 positioned printing units 12 roll on each other and print the substrate 13 on both sides.
  • the printing units 10 and 11 shown in FIG. 1 are therefore 8-cylinder printing units.
  • Each of the printing units 10, 11 is mounted on a mounting plane 18 and 19, wherein the mounting planes are also referred to as gallery levels of the web-fed rotary printing press.
  • the on opposite sides of the printing units 10, 11 arranged inking 16 and dampening 17 of the printing units 12 of the respective printing unit 10, 11 are each combined to form a coloring module 20 so that accordingly in the embodiment shown each printing unit 10, 11 two inking modules 20, each with two Ink fountain 16 and two dampening 17 includes.
  • each inking module 20 of each printing unit 10, 11 is movable relative to the other components of the printing unit, in particular relative to the cylinders 14, 15 thereof, with the aid of an air cushion conveyor.
  • a inking module 20 can be lifted off a mounting plane 18 or 19, on which it rests, so as to move the inking module 20 in the raised position relative to the remaining components of the printing unit 10, 11.
  • a dyeing module 20 can be moved in the direction of the arrow 21 in any direction between two positions. To realize a change in direction, since air cushion transport devices operate virtually frictionless, virtually no additional effort is required.
  • each inking module 20 a Vietnamesekissentransport dressed is firmly connected, which comprises at least two air cushion modules 22 in the illustrated embodiment, in each case an air cushion module 22 engages on two opposite sides of a Einärbemoduls 20. Then, when the air cushion modules associated with a colorant module are subjected to different or uneven loads, this can be compensated for by an individual pressure regulation for the airbag modules.
  • the number of air cushion modules 22 assigned to a coloring module 20 depends on the weight of the inking module and on the load capacity of the air cushion modules and can be chosen as desired.
  • each inking module using a flexible air cushion transport device, such. B. with the help of a Heilkissentransportwagen to transport.
  • the inking modules 20 no air cushion conveyor permanently assigned, but if necessary, a Heilkissentransportwagen is pushed under the inking module to be transported in order to then lift the same from the mounting plane.
  • the present invention proposes to move or transport coloring modules of a printing unit by means of air cushion transporting devices.
  • About such Gutkissentransport acquired from a printing unit with the aid of an air cushion transport device, stops are provided on the printing unit which precisely determine the operating position.
  • Clamping elements can be used to protect the operating position against dynamic influences. Only the operating position of the inking modules on the printing unit must be strictly adhered to to ensure a high print quality, but all other positions of the inking modules with respect to the respective printing unit are not codified in their position and need not be exactly achieved.
