Definitions

  • the invention relates to a drive device for the inking and dampening unit of a rotary printing press with a plurality of oscillating friction rollers which can be driven by toothing on a plate cylinder.
  • an inking unit which comprises a number of distribution cylinders which can be driven from the plate cylinder via gear trains having gear wheels.
  • the distribution cylinders are also driven in the axial direction, ie in an oscillating manner.
  • a separate drive mechanism is used to generate the traversing movements of the distribution cylinders, which is particularly complex when different adjustment options with regard to traversing stroke and phase position of the traversing movement are required.
  • the object of the invention is to provide a compact drive device for the friction in a inking and / or dampening unit, with which both the rotary drive and the traversing drive for the friction rollers are derived from the plate cylinder and the friction Rolls can be made available, an individual temporal influence on the dead positions of the traversing stroke should be possible with each friction roller.
  • the drive mentioned advantageously serves to generate the traversing movement for the friction rollers, the phase position of the traversing stroke being able to be changed in a simple manner by rotating the eccentrics assigned to each friction roller.
  • the eccentrics are rotated so that all the friction rollers never come to the end or dead position at the same time, i. H. do not reach the reversal point at the same time, which contributes significantly to the required leveling of the ink and / or dampening solution layers or films to be rubbed.
  • Fig. 1 shows schematically a printing unit 1, which comprises three blanket cylinders 2, 3 and 4 as well as three plate cylinders 5, 6 and 7, each placed on one of the blanket cylinders 2 to 4 mentioned.
  • An inking unit and a dampening unit are assigned to each of the plate cylinders 5 to 7.
  • the drive device according to the invention on each of the plate cylinders 5 to 7, i. H. is usable in all geometric installation positions, the invention is described only with reference to the drive device assigned to the plate cylinder 5.
  • Ink application rollers 8, 9 and a dampening application roller 10 are set on the plate cylinder 5.
  • the inking rollers 8, 9 receive ink from an inking roller 11 and an inking roller 12 and the dampening roller 10 receives dampening liquid via the dampening roller 13, wherein an inking roller 14 is arranged between the inking rollers 11 and 12 and the inking roller 12 receives the ink from one in FIG. 1 Ink box not shown coming is fed via an inking roller 15.
  • the inking rollers 11 and 12 and the dampening roller 13 are rotated by a central gear 16 arranged between them, which in turn is driven by the plate cylinder 5.
  • a paper web 17 can be provided with a double face print through the rubber cylinders 2 and 4 and with a back pressure through the rubber cylinder 3.
  • other paper web guides are also possible.
  • the inking and dampening unit described in connection with the plate cylinder 5 can also be used on the plate cylinder 6 and on the plate cylinder 7. This brings significant advantages in terms of rationalization.
  • the central gear 16 is driven from the plate cylinder 5. 3 and 4 that it can be seen that a helical toothing 19 meshes with a helical toothing 18 on the plate cylinder, which is arranged on a shaft 20 which is drawn in the machine side wall 21 of the printing press, which is usually drawn as side II- (drive side) , is stored.
  • the central gear 16 is also mounted on the shaft 20 and at the end of the shaft 20 (FIG. 4) a bevel drive 31 is shown, via which the shaft 20 drives a shaft 32 arranged at right angles to this.
  • drive gearwheels 11 ', 12' and 13 ' are mounted, which mesh with the central gearwheel 16, so that the grater 11 to 13 from the plate cylinder 5 through the latter are drivable here.
  • the shaft 32 arranged transversely to the shaft 20 is driven via the bevel drive 31.
  • the shaft 32 is supported on both sides.
  • an eccentric 35 is arranged on the left end of the shaft 32 and an eccentric 36 on the right end of the shaft, and an eccentric 37 is rotatably arranged next to it.
  • each of the eccentrics 35, 36, 37 can be rotated on the shaft 32. Due to the position of the eccentrics 35, 36, 37 on the shaft 32, an individual temporal influence on the traversing movement, i. H.
  • the eccentrics 35, 36, 37 are set so that never all three friction rollers 11, 12, 13 their end positions at the same time, i. H. their turning points.
  • a preferred setting position of the three eccentrics 35, 36, 37 is indicated by the letters X, Y, Z in FIG. 3.
  • Bearings 38, 39, 40 sit on the eccentrics 35, 36, 37, on each of which a rocker arm 41, 42, 43 is mounted.
  • the rocking lever 42 is cranked since the friction rollers 12, 13 are arranged one above the other.
  • rocker arms 41, 42, 43 are also held at their pivot points on the fastening plates 33, 34, only the fastenings 44 and 45 for the rocker arms 41, 42 being shown in the views shown (FIGS. 3 and 4).
  • Fig. 2 shows best that on each of the rocker arms 41, 42 and 43, a pin 46, 47 and 48th is attached, which carries one of the sliding blocks 28, 29, 30 already mentioned.
