Definitions

  • the invention relates to an inking unit for a Rotogravure printing press according to the Claim 1.
  • the end faces of the forme cylinder can Printing ink.
  • GB 532 460 A discloses a printing press with one Forme cylinder that prints a web directly. This The forme cylinder is moved by a roller that is immersed in ink colored. This forme cylinder does not dive into one Color filled paint tray.
  • the invention is based on the object improved gravure inking unit to the state of the art create.
  • ink tray filled to the brim with gravure ink 1 2 dip a inking roller 3 and a forme cylinder 4 a.
  • the paint pan designated as a whole has 2 a clear length l on.
  • the forme cylinder 4 has one Bale length m on both sides, the inside length l of the Ink tray 2 (inking length of the forme cylinder 4) each protrudes an amount or an excess x or y.
  • the value x can be equal to y. However, it is also possible that x is greater than y or y is greater than x.
  • a supernatant x or y also includes the amount in each case Material thickness of an end face 8, 9 of the paint tray 2.
  • End faces 6, 7 of the forme cylinder 4 are thus located outside the paint tray 2 and are not connected with the gravure ink 1.
  • End faces 8, 9 of the ink tray 2 therefore point towards the forme cylinder 4
  • Side a recess with a radius r, which is a few millimeters larger than the radius s of the Forme cylinder 4, so that between the radii r, s a gap 11 is formed in each case.
  • the Recess of each end 8, 9 corresponds to one of the Radius s of the forme cylinder 4 adapted gap 11.
  • the inking roller 3, the z. B. no own drive depending on the diameter of the forme cylinder 4, e.g. B. with 5/6 of their diameter or up to their entire diameter in gravure ink 1 a.
  • the inking roller 3 is on its outer surface covered with a textile cover and stands on the side spaced, e.g. B. at a distance b from FIG. 1 to the left of a vertical plane through an axis of rotation 12 of the forme cylinder 4 below in frictional contact with the jacket of the forme cylinder 4.
  • the distance b is about that one to two times the diameter of the inking roller 3.
  • the forme cylinder 4 is via its journal 13, 14 in Side frames 16, 17 (clockwise according to Fig. 1) rotatably mounted.
  • the inking roller 3 is not a shown, ink tray-proof lever system rotatable stored (see DE 40 30 377 A1).
  • a bottom plate 17 of the paint pan 2 is in the center one end of a rack 19 positively connected.
  • the rack 19 is in a fixed, not shown guide slidable, but not rotatably mounted.
  • a pinion 21 stands with the Teeth of the rack 19 in engagement and is via a shaft 22 with a reduction gear connected to stepper motor 23 and a counter 24.
  • the counter 24 serves as an indication of the current one Height adjustment of the ink tray 2 and is a measure of that Immersion depth of the forme cylinder 4 to use or for the adjustment of the height of the ink tray 2 to another Diameter of another forme cylinder 4.
  • one Rack 19 can also be two in parallel at a distance Toothed racks with a common one Drive may be provided.
  • a trough fixed to the frame 26 which both from the columns 11 emerging gravure ink 1 as well as that of a doctor blade device designated overall by 27 doctored gravure ink 1 and this over an ink circulation device, not shown with the addition of new gravure ink 1 to the ink tray 2 feeds.
  • the doctor device 27 is fixed on the side frame on an axis 28 against the forme cylinder 4 one in the horizontal plane perpendicular to Rotation axis 12 of the forme cylinder 4 adjustable Stop 30 arranged and pivoted and does not wear one on her swiveling head shown clamping device for a doctor blade 29.
  • the doctor device 27 is below the Doctor blade 29 in the vicinity of the end faces 6, 7 with squeegee-fixed or side frame-fixed nozzles 31, 32 provided which solvents for gravure ink 1, e.g. B. toluene finely divided as spray 33, 34 into the areas of the projections x, y of the forme cylinder 4 spray the paint tray 2 on both sides tower over.
  • solvents for gravure ink 1, e.g. B. toluene finely divided as spray 33, 34 into the areas of the projections x, y of the forme cylinder 4 spray the paint tray 2 on both sides tower over.
  • the Nozzles 31, 32 each have a feed 35 for Toluene or compressed air.
  • the doctor device 27 can advantageously also work iridescent, which is another more uniform color distribution on the surface of the Forme cylinder 4 takes place.
  • the forme cylinder 4 is a Forme cylinder 4 pressing, rotatable impression 36 arranged, which on both sides via its axle journals 37, 38 mounted in rockers 39, 41 and each with a side frame fixed and height adjustable, carriage, not shown, non-positive and positive connected is.
  • the bale length m of the forme cylinder 4 can, for. B. are between two and three meters.
