Definitions

  • the invention relates to an ink application bar for a rinse inking unit of a rotary printing press according to the preamble of claim 1.
  • DE-OS 31 35 711 shows a flushing inking unit for a rotary printing press.
  • the flushing inking unit consists of an ink application bar and two doctor blades arranged above and below it, which together with an anilox roller form an ink distribution channel.
  • the cross section of this ink distribution channel is rectangular and each has an additional edge in the area of the doctor blade.
  • the US-PS 41 58 333 shows a flushing inking unit, which is also employed on an anilox roller having cups.
  • the flushing inking unit has a doctor blade arranged underneath and a number of vertical walls which are provided with openings.
  • a disadvantage of the one shown by the US-PS 41 58 333 The device is the suitability of the flushing inking unit for only one direction of rotation of the anilox roller.
  • the ink flow through stationary walls and openings does nothing to change the pressure of the ink on the anilox roller.
  • there is an extraordinarily large space requirement for the flushing inking unit which is many times larger than in the case of a conventional ink application bar.
  • the invention has for its object to provide an ink application bar for a rinse inking unit of a rotary printing press, which favors the flow of ink in the ink chamber.
  • the advantages of the invention are, in particular, that by building up a uniform ink flow without turbulence, even ink contact with the inking roller is possible even at high peripheral speeds, and ink liquid pressure can be regulated to better fill the cells of the inking roller.
  • a inking roller designed as anilox roller 1 is rotatably mounted in inking units (not shown).
  • the anilox roller 1 forms, with an ink application bar 2 arranged parallel to its axis of rotation, an upper doctor blade 3 and a lower doctor blade 4, a roller-long ink distribution chamber 6.
  • the ink distribution chamber 6 has smooth, rounded inner walls 7. In the middle of the ink distribution chamber 6 there is a hole 9 for the ink supply, which can be connected to an ink supply device, not shown.
  • the paint knife 3 is screwed from the outside to an upper slope 11, the doctor blade 4 from the outside to a lower slope 12 of the paint application bar 2.
  • the color distribution chamber 6 is covered on its end faces by means of side plates 14, 15 which, for. T.
  • a profile body 16 is pivotally mounted in side plates 23, 28 by means of shaft journals 19, 21 attached to its end faces 17, 18.
  • the side plates 23, 28 are each screwed to the side of the paint application bar 2, so that the side plates 14, 15 each between the paint application bar 2 and the side plates 23; 28 are arranged.
  • the profile body 16 is almost as long as a width b of the anilox roller 1.
  • the profile body 16 is elliptical in cross section.
  • a pivoting of the profile body 16 about its axis of rotation 22 thus results in a change in the smallest gap width S O.
  • the gap S is formed by the anilox roller 1 and the lateral surface 24 of the profile body 16 facing the anilox roller 1.
  • a force F of the ink in the gap S is greatest just before the smallest gap width S O , as seen in the direction of rotation of the anilox roller 1.
  • the load capacity f / b of the printing ink and thus the force of the ink on the cups 28 of the anilox roller 1 can be calculated using the following formula: (see also VDI research booklet 391, pages 82 - 85)
  • ⁇ toughness of the color
  • r1 radius of the anilox roller 1
  • r2 radius of the outer surface 24 facing the anilox roller 1
  • v1 peripheral speed of the anilox roller 1
  • b length of the profile body 16.
  • a change in the smallest gap width S o thus has an immediate change in the force of the color on the Anilox roller 1 result.
  • the profile body 16 is pivoted by adjusting devices 31, 32 attached to the outside of the side plates 23, 28 in each case.
  • the adjusting devices 31, 32 each consist of an adjusting spindle 33, 34 which is passed through a threaded through hole 38; 39 one on the side plate 23; 28 attached bracket 36; 37 is screwed through.
  • At each end 41; 42 has the adjusting spindle 33; 34 a ball 43; 44, which in a vertical guide groove 46; 47 a lever 48; 49 engages.
  • the lever 48; 49 is on the through the side plate 14; 15 and the side plate 23; 28 protruding shaft journal 19; 21 rotatably arranged.
  • the adjusting spindle 33; 34 has an adjusting head 51; 52 on the z. B. can be knurled so that it is easy to use by hand. Of course, it is also possible to arrange a servomotor there for the purpose of remote adjustment.
  • the profile body 16 is by means of the adjusting devices 31, 32 from a central position shown in dashed lines in FIG. 2, depending on the direction of rotation of the anilox roller 1 and the required force F of the ink on the anilox roller 1 by an angle ⁇ z. B. can be swung out ⁇ 20 °.
  • FIG. 1 shows with a solid line a pivoting position of the profile body 16 for an anilox roller rotation direction in the clockwise direction.
  • the dash-dotted line indicates a possible position of the profile body 16 for a direction of rotation of the anilox roller 1 counterclockwise.
  • profile bodies 53, 54, 55
  • 5 shows a cross section of the profile body 53 which has a convex shape on a side facing the anilox roller 1 and a concave shape on a color backflow side.
  • the ends of the profile body 53 are rounded, one rounding having a larger radius than the other (wing profile).
  • the profile body 54 in FIG. 6 essentially corresponds to the profile body 53, but with the same end radii.
  • the profile body 56 in FIG. 7 has two concave outer surfaces.
  • a cylindrical profile body 57 is arranged within a circular color distribution chamber 58.
  • the profile body 57 is rotatably mounted in the side plates 23, 28 and is set against the anilox roller 1.
  • the profile body 57 is driven by the anilox roller 1 by friction.
  • means for example, mounting the profile body 57 in eccentric bushes) for changing the center distance of the profile body 57 and anilox roller 1, as a result of which there is greater slippage between the anilox roller 1 and the profile body 57.
