Definitions

  • the invention relates to a dryer system for arcuate Substrates in a rotary printing press according to the preamble 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 assigned, known.
  • This drying device is fixedly disposed within a transfer drum, wherein the transfer drum between printing units in series construction is arranged.
  • a dryer system is known in a drying device a sheet-guiding cylinder is assigned, with this arc-guiding cylinder between two coating units is arranged.
  • U1 is a rotary printing press for arcuate substrates known in the offset printing, at least one flexographic printing unit and painting units combined are arranged.
  • a drying device in the one provided with a paint job arcuate Printing material is first supplied to a hot air stream and then a UV radiation on the substrate surface acts. For the purpose of cooling the sheet-shaped printing material before being deposited on a delivery pile, the sheet becomes arcuate Substrate cooled with cold air.
  • the disadvantage here is that arranged at between printing units Dryer devices heat transfer to the can be done adjacent printing units. Such heat transfer can cause functional impairment in the neighboring Printing units or too high a temperature load in the delivery pile, as in the delivery arranged drying units is known.
  • the invention is based on the object, a dryer system of the type described above to provide that said Disadvantages avoids that in particular the adherence of stable working temperatures allowed and the Temperature load on adjacent printing units noticeably reduced.
  • a first advantage of the dryer system according to the invention is based in that the dryer system to the adjacent upstream and downstream printing units, including flexographic printing units and / or coating units, a temperature barrier means a Abschott proposed has. This will be in Rotary printing machines functionally stable processing temperatures guaranteed, including a defined Temperature in the delivery pile. A possible heat transfer, For example, by drying paint or paint in shows each work is also in the neighboring printing works (including flexographic printing or coating plants) preventable.
  • the Abschott drove additionally the leadership of the sheet-shaped substrate by its pneumatic loading supported by the funding direction.
  • the embodiment of the dryer system according to the invention is not on an arrangement of only one dryer unit between printing units, flexographic printing units and / or coating units, limited. Rather, as well as a multiple arrangement of Dryer units between upstream and downstream printing units, Flexographic printing units and / or coating units, feasible, wherein each dryer system associated with a sheet guiding cylinder is.
  • a multi-color offset rotary printing machine consists of a plurality of printing units 1, which each have a plate cylinder 8, a blanket cylinder 9 and a printing cylinder 11 as a sheet guiding cylinder.
  • Each plate cylinder 8 is at least one inking unit not described in detail, optionally associated with a dampening unit.
  • a first coating unit 2 is arranged downstream of the last printing unit 1.
  • Such a coating unit 2 has a forme cylinder 12 and an associated metering system 13, for example formed from a chambered doctor blade and a screened applicator roller, and a printing cylinder 11 as a sheet guiding cylinder.
  • the first coating unit 2 is followed in the conveying direction 17 by two modularly constructed dryer units 4.
  • Each dryer unit 4 consists inter alia of two sheet guiding cylinders, which in the present example are formed by a transfer cylinder 10 and a printing cylinder 11.
  • a second coating unit 3 is arranged downstream.
  • 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 in each case by a transfer cylinder 10 as a sheet guiding cylinder.
  • a single-size forme cylinder 12 or blanket cylinder 9 single-turn shaft
  • the coating unit 3 is followed by a downstream boom 5 with an endlessly circulating conveyor system 7, which ab vitamint the sheet-shaped substrates from the coating unit 3 and stores 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 for assisting the guidance of the sheet-shaped printing material fixed on the printing cylinder 11 in the gripper closure.
  • the guide 16 is formed by guide bar or baffle with a corresponding hole pattern or a grid structure.
  • the printing cylinder 11 as a sheet guiding cylinder is assigned a drying device 15 within the first dryer unit 4 above the guide 16. This drying device 15 is preceded in the conveying direction 17, preferably over the width of the printing cylinder 11 extending Abschott sensible 14.
  • the printing cylinder 11 of the first dryer unit 4 is followed in the conveying direction 17 by the second dryer unit 4, which in turn has a transfer cylinder 10 and a downstream printing cylinder 11 as a sheet guiding cylinder.
  • a guide 16 is arranged analogously to the first dryer unit 4.
  • a dryer device 15 is associated with the printing cylinder 11 adjacent to a defined distance.
  • This dryer device 15 is preferably one of the Width of the printing cylinder 11 extending Abschott Rhein 14 downstream in the conveying direction 17.
  • each screening device 14 is designed as a nozzle arrangement, which with blown air from the ambient air and / or Cold air can be acted upon pneumatically.
  • This pneumatically can be acted upon nozzle arrangement has a plurality of openings in the form of perforated and / or slot nozzles, which preferably over the width of the printing cylinder eleventh extend.
  • the processing temperatures in the Dryer units 4 themselves and the adjacent coating units 2, 3 are functionally stable.
  • the Abschott Publisheden 14 form thus a Luftabschottung or an air lock off.
  • a Arrangement of the Abschott driving 14 is in the immediate Neighboring to the dryer devices 15 (FIG. 2, FIG. second dryer unit 4) or at a defined distance to the dryer devices 15 ( Figure 2, first dryer unit 4) feasible.
  • the embodiment of the invention is not on the described Example limited. Rather, only one is Dryer unit 4 between two adjacent printing units, Flexographic printing units and / or coating units, can be arranged.
