Definitions

  • the invention relates to a dryer system for arcuate Printing materials in a rotary printing machine according to the generic term of the main claim.
  • a dryer system of this type is known from DE 36 32 744 A1 a drying device, which a sheet-guiding cylinder is known. This drying facility is fixedly arranged within a transfer drum, wherein the transfer drum between printing units in series is arranged.
  • a dryer system for which a dryer means a sheet-guiding cylinder is assigned, this arc-guiding cylinder between two coating units is arranged.
  • U1 is a rotary printing press for sheet-shaped substrates known in the offset printing units, at least one flexographic printing unit and coating units combined are arranged.
  • a dryer device in the case of an arched one provided with a lacquer application Substrate is first fed a stream of hot air and then UV radiation on the substrate surface acts. To cool the sheet-like printing material before being placed on a stack of cantilevers, the sheet is arched Media cooled with cold air.
  • the disadvantage here is that arranged between printing units Dryer devices transfer heat to the neighboring printing units can take place. Such heat transfer can lead to functional impairments in the neighboring Printing units or too high a temperature load lead in the boom stack like this from in the boom arranged dryer units is known.
  • the invention is based on the object of a dryer system of the type described in the introduction to create that Disadvantages avoids that in particular compliance with functionally stable processing temperatures allowed and The temperature load of neighboring printing units is noticeably reduced.
  • a first advantage of the dryer system according to the invention is justified that the dryer system to the neighboring upstream and downstream printing units, including flexographic printing units and / or coating units, a temperature lock by means of has a partitioning device. So that in Rotary presses functionally stable processing temperatures guaranteed, including a defined one Temperature in the boom stack. A possible heat transfer, which, for example, by drying paint or varnish in the each work shows is also in the neighboring printing works (including flexographic printing or coating units) can be prevented.
  • Another advantage is that the bulkhead pneumatically using ambient or cold air as blowing air is operable.
  • the bulkhead facility also leads the sheet-shaped printing material through its pneumatic action supported considering the direction of funding.
  • the formation of the dryer system according to the invention is not an arrangement of only one dryer unit between printing units, flexographic printing units and / or coating units, limited. Rather, there is also a multiple arrangement of Dryer units between upstream and downstream printing units, Flexographic printing units and / or coating units, realizable, each dryer system assigned to a sheet guide cylinder is.
  • a multicolor offset rotary printing press consists of a plurality of printing units 1, each of which has a plate cylinder 8, a blanket cylinder 9 and a printing cylinder 11 as a sheet guide cylinder.
  • Each plate cylinder 8 is assigned at least one inking unit, not described in detail, possibly a dampening unit.
  • a first coating unit 2 is arranged after the last printing unit 1 in the conveying direction 17 of the sheet-shaped printing materials.
  • Such a coating unit 2 has a forme cylinder 12 and an associated metering system 13, for example formed from a chamber doctor blade and a rastered application roller, and a printing cylinder 11 as a sheet guide cylinder.
  • the first coating unit 2 is followed in the conveying direction 17 by two modular dryer units 4.
  • Each dryer unit 4 consists, among other things, of two sheet guide cylinders, which in the present example are formed from a transfer cylinder 10 and a printing cylinder 11.
  • a second coating unit 3 is arranged downstream of the second dryer unit 4 in the conveying direction 17.
  • the coating unit 3 is constructed analogously to the coating unit 2.
  • Each printing cylinder 11 in the printing unit 1 and the coating units 2, 3 is preceded by a transfer cylinder 10 as a sheet guide cylinder.
  • all (including those of the dryer units 4) sheet-guiding cylinders, transfer cylinders 10 and impression cylinders 11 are double-sized.
  • the coating unit 3 is followed by a downstream delivery arm 5 with an endless circulating conveyor system 7, which conveys the sheet-like printing materials from the coating unit 3 and deposits them on a delivery stack 6.
  • the first dryer unit 4 in the conveying direction 17 has a guide device 16 arranged above the printing cylinder 11 to support the guidance of the sheet-like printing material fixed on the printing cylinder 11 in the gripper closure.
  • the guide device 16 is formed by a guide bracket or a guide plate with a corresponding hole pattern or a lattice structure.
  • a dryer device 15 within the first dryer unit 4 is assigned to the printing cylinder 11 as a sheet guide cylinder above the guide device 16. This dryer device 15 is preceded in the conveying direction 17 by a partitioning device 14 which preferably extends over the width of the printing cylinder 11.
  • the printing cylinder 11 of the first drying unit 4 is followed in the conveying direction 17 by the second drying unit 4, which in turn has a transfer cylinder 10 and a downstream printing cylinder 11 as a sheet guiding cylinder.
  • a guide device 16 is arranged analogously to the first dryer unit 4.
  • a drying device 15 is in turn associated with the printing cylinder 11 at a defined distance.
  • This dryer device 15 is preferably one over the Width of the pressure cylinder 11 extending partition device 14 downstream in the conveying direction 17.
  • each partition device 14 is designed as a nozzle arrangement, which with blowing air from the ambient air and / or Cold air can be acted upon pneumatically.
  • This pneumatic actionable nozzle arrangement has a plurality of openings in the form of perforated and / or slot nozzles, which preferably across the width of the impression cylinder 11 extend.
  • the processing temperatures in the Dryer units 4 themselves and the neighboring coating units 2, 3 are functionally stable.
  • the bulkhead devices 14 form thus an air partition or an air barrier.
  • a Arrangement of the bulkhead 14 is in the immediate Neighborhood to the dryer devices 15 (FIG. 2, second dryer unit 4) or at a defined distance to the dryer devices 15 (FIG. 2, first dryer unit 4) realizable.
  • the training according to the invention is not based on the described Example limited. Rather, it is just one Dryer unit 4 between two adjacent printing units, Flexographic printing units and / or coating units, can be arranged.
