Definitions

  • the invention relates to an inking unit for a printing unit of a Ro L Lenrot at i onsdruc k aschi ne according to the preamble of claims 1, 2 and 3.
  • a short inking unit for a rotary printing press has become known from GB-PS 18 907 and DE 195 35 266 A1.
  • the following measures are provided to improve the printing ink application on a forme cylinder:
  • a first inking roller has a smaller diameter than the form cylinder
  • first ink transfer roller (rider roller) is attached to the first inking roller
  • This additional inking unit roller is an inking roller connected to a central inking roller - here, for. B. a rider roll
  • the further inking roller based on the direction of rotation of the central inking roller, is in contact with the central roller before the first inking roller.
  • DE 35 45 720 A1 shows a short inking unit with an anilox roller, with the non-rasterized Full of color, good color coverage should be achieved.
  • the same principle of printing is applied as in the above-mentioned publications GB-PS 18 907 and DE 195 35 266 A1. This is because two inking rollers are used, both of which are in contact with an anilox roller. After the printing ink has been delivered by the first inking roller to a first roller, its residual printing ink application is given to an inking roller in accordance with the inking law. This then delivers ink to the first roller.
  • the invention has for its object to provide an inking unit for a rotary printing press.
  • the inking unit can be realized in a low overall height and, when using chambered doctor blades or doctor blade devices, directly on a central printing ink "distributing" ink roller, even in a short overall length.
  • two inking rollers can be set up with a plurality of inking rollers, each applying an ink to a common forme cylinder.
  • Fig. 1 is a side view of a schematic
  • FIG. 2 shows an illustration analogous to FIG. 1, but with an inking unit with a rider roller placed on the inking roller;
  • the diameter of the central roller 2 can be the same, larger or smaller than the diameter of the rollers 12, 16, 29 or 3, 17, 31. It corresponds to a non-integer multiple of the aforementioned rolls.
  • the aforementioned rollers can all have different diameters.
  • each inking roller 12; 13 additionally one on the inking roller 12; 13 acting rider roller 38; 39 in contact (Fig. 2).
  • the roll neck 41; 42 of the rider roller 38; 39 are in the ends of a pair of holding arms 43 and 44 on the rockers 8; 9 rotatably attached.
  • the roller 38; 39 is in each case by means of a tension or compression spring 28 on the outer surface of the inking roller 12; 13 pulled or pressed.
  • the rider rolls 38; 39 have a z. B. hard oleophilic surface (plastic or metal) and can also be made iridescent.
  • each inking roller 12; 13 and the ink roller 16; 17 is pivotable on the carrier 8; 9 at least one rider roller 29; 31, e.g. B. with a hard oleophilic surface, e.g. B. made of plastic, "Rilsan” arranged. It is against the force of one on the wings 8; 9 supporting spring 32 pressed onto the jackets of the inking roller 12 or 13 and the inking roller 16 or 17 (Fig. 2).
  • the axle journals 33; 34 of the rider rollers 29; 31 in each case at first ends of pivotably mounted pivot arms 36; 37 stored.
  • the second ends of the swivel arms 51 are on the rockers 8; 9 hinged. All or individual rollers of both inking rollers 20; 25 can be iridescent, d. H. be designed as a distribution roller.
