Definitions

  • the invention relates to a device for processing viscous or highly viscous fluids for refining Print products in a finishing unit on one Rotary printing press according to the preamble of claim 1.
  • DE 34 27 898 C1 discloses a device for applying Liquid, in particular a paint unit for a Printing press. With this solution from the prior art there are jams in the gusset area of two rollers, the individual connecting the gusset areas Have channels.
  • the present Invention the object of the invention Device widest possible spectrum from To be able to process suitable fluids.
  • the object is achieved in that the Dosing roller swiveling or over a swiveling roller or over the feed roller can be supplied from a paint tray.
  • the advantage of the solution according to the invention is that according to the rheological properties of the Surface of the printing material refining fluid, which for the processing of which is selected in the optimal funding principle can. All that is required is either pivoting the Metering roller or swiveling one roller into another Position; in this way can be compact both the dip roller principle and the roller wedge principle realize.
  • Developments of the invention lying thought provide the metering roller along a Travel between two stationary rollers move. This is an indirect order from the Refinement fluids via one of the paint-guiding cylinders in the Plate cylinder possible.
  • a roller wedge which is formed between the metering roller and a squeeze roller is arranged, a second paint supply whereby a Paint supply as close as possible to the roller wedge is ensured. With the one below a feed roller box-shaped collecting sheets can be a Mixing of the excess fluid can be achieved.
  • finishing unit provided a stationary metering roller and Pinch roller a switchable in its direction of rotation Assign feed roller.
  • Assign feed roller When the feed roller rotates in The processing fluid is conveyed clockwise from a tub; when the feed roller rotates against the The paint supply is clockwise above the Supply roller arranged paint supply guaranteed.
  • a rubber roller assigned to the metering roller together with a paint supply in a first and in a second position is pivotable.
  • Rubber roller and paint supply can do this of course also implemented manually in the different positions will.
  • a separate Squeeze roller is not necessary, as this is due to the roller wedge in the second position limiting rubber roller is formed.
  • the finishing unit 1 shown in Figure 1 comprises a in the positions 2 'and 2' 'swiveling metering roller 2. Das Swiveling the metering roller 2 takes place along the Travel 11. The metering roller 2 is both at a Feed roller 3, as well as on a squeeze roller 4.
  • a paint supply 5 Located above the nip roller 4 and wedge elements 7 a paint supply 5; above the feed roller 3 is one set up another paint feed 6. Under the feed roller 3 are cascade-shaped collecting plates 8 and 9 attached, under which a paint tray 10 extends up to a paint cylinder 12. Above the Lacquer blanket cylinder 12 is a plate cylinder 13, via which an indirect paint application at position 2 '' pivoted metering roller 2 can be done. Below the paint-bearing cylinders 12 and 13 is located Printing cylinder 14, on which printing sheets from be transferred to a transfer drum 15.
  • a Roller wedge 26 between the metering roller 2 and the one Side wall 18 of the stationary squeeze roller 4 educated.
  • the paint supply 5 supplies the roller wedge 26 with Paint so that the plate cylinder 13 is supplied with paint.
  • This indirect paint application called working mode through the plate cylinder 13 of the blanket cylinder 12 with paint supplied, which in turn on the circumference of the multi-large executed printing cylinder 14 located sheet refined.
  • the metering roller 2 is pivoted into position 2 ', it is in contact with the roller surface of the Feed roller 3.
  • the feed roller 3 can do the printed products finishing fluid can be supplied via a paint feed 6.
  • a paint holder is also from the collecting plate 8 possible, under which another collecting plate 9 with arcuate contour is arranged.
  • the to the stationary in the side walls 18 of the finishing unit 1 Feed roller 3 employed metering roller 2 takes the fluid from from the jacket of the feed roller 3 and carries it in the way of direct paint job on the paint cylinder 12 on the print product to be refined.
  • Below the in position 2 '' pivoted metering roller 2 and the collecting plates 8 and 9 extends a paint tray 10, which of the Transfer drum 15 on the circumference of the printing cylinder 14 protected sheet protects against splashes.
  • Figure 2 shows the configuration of a finishing unit again, with a feed roller in two directions is drivable.
  • the feed roller 3 are the Pinch roller 4, the metering roller 2 and the Paint cylinder 12 stationary in the side walls 18th stored.
  • a paint feed 6 arranged below the Feed roller 3 is a paint tray 10.
  • Den Roller wedge 26 have laterally delimiting wedge elements 7 one - based on the paint tray 10 - paint inlet 16, through which excess fluid in the paint tray 10th can be directed.
  • the paint tray 10 has a Paint drainage 17.
  • Figure 3 finally shows a finishing unit a metering roller swiveling between two positions assigned rubber roller.
  • the metering roller 2 is assigned a roller 20, which as Rubber roller can be formed and in a first position 20 'and a second position 20' ' is pivotable.
  • a paint supply 21 arranged, also from a first position 21 'into a second position 21' ' is.
  • the paint supply 21 describes during its movement a semi-circular pivot path 22, while the Roller 20 describes a pivot path 23.
  • the Sidewalls 18 are stationary a paint tray 25, Wedge elements 7 on both sides of the roller wedge 26, as well as below the position 20 'added a paint tray 10.
  • the paint is supplied according to the dip roller principle.
  • a control of the on the Metering roller 2 to be applied would be over the amount of paint Position 20 'fixed immersion depth of the roller 20 achievable.
  • the paint is applied in position 20 'on the Surface of the metering roller 2 from there to the Lacquered blanket cylinder 12 refining the surfaces of the printing material.
