Definitions

  • the invention relates to a printing press with at least one doctor blade inking unit, which delivers the ink to an anilox roller.
  • the invention has for its object to provide a printing machine of this type, in which a change of colors during production changes is simplified and facilitated.
  • Each printing unit comprises a blanket cylinder 4, a plate cylinder 5, an inking cylinder 6 and an anilox roller 7.
  • a dampening unit 8 is also assigned to each plate cylinder 5.
  • Each anilox roller is supplied with ink by means of a doctor blade inking unit, designated 9 in total. All squeegee inking units 9 are identical to one another.
  • a doctor blade inking unit 9 consists of a chamber doctor blade 10 with a support 11 and an ink supply device 12.
  • the chamber doctor blade 10 is connected to the ink supply device via a hose 13, one end of which is connected to the carrier 11 of the carrier 11 by means of a releasable hose coupling 14
  • Chamber doctor 10 can be connected while the other end of the hose 13 is connected to the ink supply device.
  • the ink supply device 12 comprises an ink pan 15, which is open at the top and a slot 16 is provided in the side walls of each.
  • a paint pump 17 is arranged below the paint tray, the drive shaft 18 of which projects out of the housing of the paint pump 17.
  • a holder 19 is provided in front of each anilox roller 7 for connecting a chambered doctor blade 10.
  • the holder 19 is seated on a cross member 20, which is rotatably supported at both ends on side walls 21 of the printing press, and comprises two holders 22 which are placed at a distance from one another on the cross member 20 and each have two retaining lugs 23.
  • Two bolts 24, which are fixedly attached to the carrier 11, can be suspended in the retaining lugs.
  • an eccentric 26 which can be rotated by means of a hand lever 25 is also mounted, which acts on the upper side of the support 11 and can thereby hold the bolts 24 in firm contact with the holding projections 23.
  • a further holder 27 which comprises a support plate 28 and a further cross member 29. Both the support plate 28 and the cross member 29 are connected to the side walls 21 at both ends.
  • the crossbeam 29 carries a plurality of bearings 30 in which a main shaft 31 is guided. One end of the main shaft 31 passes through a side wall 21 and is fixedly coupled to a motor 32.
  • the main shaft 31 is connected to output shafts 35 via a plurality of branching gears.
  • the branching gears are designed so that a plurality of bevel gears 33 are placed on the main shaft 31, each with one also comb bevel gear 34 mounted on the crossmember 29.
  • Each bevel gear 34 is firmly seated on an output shaft 35, on the free end of which a coupling part 36 with claws 37 is placed.
  • the coupling part 36 interacts with a counter-coupling part 38, which is firmly attached to the drive shaft 18 of the ink pump 28.
  • the mating coupling part 38 also carries claws 39.
  • FIG. 3 shows a traverse 29 for a printing machine in which four doctor blades 10 are arranged side by side. Accordingly, four brackets 19 are arranged side by side on the cross member 20.
  • the machine can also be designed only for a chamber doctor blade extending over the full length of the cylinders or for another number of chamber doctor blades which are arranged next to one another.
  • a squeegee inking unit 9 starting from the position shown in FIGS. 1 and 2, is to be exchanged for another one which contains a different color
  • the clamping of the support 11 relative to the holder 22 is released by actuating the hand lever 25.
  • the bolts 24 can then be removed from the retaining lugs 23.
  • the chambered doctor blade 10 is suspended with the carrier 11 by means of the two front bolts 24 in the slots 16 of the side walls of the ink tray 15.
  • the ink supply device 12 is then pulled off from the support plate 28 in the direction of arrow a.
  • the counter-coupling half 38 separates from the coupling half 36.
  • the doctor blade inking unit can now be parked in the position shown in FIG. 4 or used at another location on the printing press.
  • the selected arrangement of the ink tray in a plane below the anilox roller 7 has the further advantage that the ink, which is doctored off by the anilox roller 7 from the anilox roller 7, can drip back directly into the ink tray 15.
  • the drive shaft 18 has an end cone which forms the counter-coupling half 50.
  • Each coupling half 51 is formed by a bush, which is firmly placed on the output shaft 35.
  • the socket has a tapered inner wall.
  • a conically wound spring 52 is also fixed to it at one end.
  • the drive shaft 18 with the counter coupling half 50 is pushed in the direction of arrow b into the coupling half 51 designed as a seeker until the spring 52 bears firmly against the conical inner wall of the counter coupling half 50.
  • the ink supply device on the support plate 28 is secured against displacement against the direction of the arrow b by a latch or a catch, not shown, so that the coupling cannot be released during operation.
