Definitions

  • the invention relates to a flushing inking unit for a rotary printing press according to the preamble of claim 1.
  • the object of the invention is therefore to improve the known rinsing inking unit in that a sensitive adjustment of the doctor blade is made possible.
  • an inking unit in which the ink head fed under pressure with the ink can be adjusted to the ink application roller with its ink outlet slot in that the ink application head is pivotally mounted in the printing machine frame via levers below the ink application roller and via a screw spindle, which is screwed into a threaded hole in the printing machine frame and can be pressed against the inking roller.
  • the ink head can also not be sensitive to the inking roller because almost the full weight of the inking head rests on the pressure serving spindle, so that it must be lifted with the spindle.
  • doctor blade is expediently made of a more elastic material than the other, so that the doctor blades are in good contact with the anilox roller even when the doctor blades are not exactly aligned with the latter. Due to its greater elasticity and flexibility, the more elastic doctor knife compensates for possible misalignments of the ink application bar.
  • the anilox roller 1 forming the inking roller is mounted in inking units 2, 3.
  • Carrier plates 4.5 are screwed onto the inking blocks 2 and 3, on which bearing blocks 6, 7 are fastened.
  • a shaft 8 is rotatably and longitudinally displaceably, which is square in the section lying between the bearing blocks 6, 7.
  • the cages 6, 7 of the Kugelumlauflac for the shaft 8 extend across the width of the bearing blocks 6, 7 also.
  • the shaft 8 is extended to the right.
  • a guide piece 12 On the protruding part of the shaft 8, a guide piece 12 is rotatably supported, but is secured against longitudinal displacement on the shaft 8 by a locking ring 13 engaging in the shaft 8.
  • the guide piece 12 has a fork 14 into which a ball bearing 15 is fitted, the inner ring of which is fastened in the bearing block 7 by means of a bolt 16. With this arrangement, the guide piece 12 is prevented from rotating with respect to the shaft 8, the movement, i. H. the squeegee movement in the direction of the longitudinal extension of the shaft 8 is, however, possible.
  • This squeegee movement is generated by an electric motor 17 which is screwed to a bearing housing 18 fastened to the inking unit 3.
  • a shaft 19 is rotatably mounted, in which the drive pin 20 of the electric motor 17 engages.
  • an inner ring of a ball bearing 21 is fastened eccentrically, the outer ring of which is fitted into a groove 22 which is incorporated in a plate 23.
  • the plate 23 is attached to the guide piece 12 so that the eccentric movement of the ball bearing 21 is transmitted to the shaft 8 as a reciprocating movement.
  • a lever 25 is clamped on the protruding part of the shaft 8, the free end of which is articulated to the piston rod of a pneumatic cylinder 26.
  • ears 27 are provided which are articulated to a fork 28 worked on the plate 23, so that the pneumatic cylinder 26 can move freely when actuated.
  • the shaft 8 can be pivoted about its longitudinal axis and thereby pressed against the anilox roller 1 or raised from it.
  • a bar 30 which is reinforced at its end is fastened, to which a paint application bar 31 is screwed by means of two toggle screws 32 distributed uniformly over the length of the paint application bar 31.
  • the toggle screws reach through somewhat larger through holes in the bar 30, so that the paint application bar 31 can be moved to a limited extent.
  • adjustable stop screws 33 are provided at a suitable distance from one another, against which the application bar 31 can strike, so that it assumes the intended position relative to the anilox roller 1.
  • a doctor blade 34 and a doctor blade 35 are screwed to the ink application bar 31. Therefore, a cavity 36 is formed between the anilox roller 1, the ink application bar 31 and the knives 34, 35, which is enlarged by a recess 37 which extends over the entire length of the ink application bar 31.
  • a hose 38 feeds the cavity 36 via a pipe 39 in a manner not shown.
  • cover plates which, for. T. also cover the end faces of the anilox rollers 1. These cover plates do not close exactly to the anilox roller 1, so that paint and any contaminants in the paint can flow there, which are collected in a drip plate, not shown.
  • the focus of the ink application bar 31 is under the shaft 1 such that it already bears against the anilox roller 1 by its own weight. If the color is to be changed, the ink application bar 31 can be lifted from the anilox roller 1 by actuating the pneumatic cylinder 26 and can be removed from the machine after loosening the screws 32. By actuating the pneumatic cylinder 26 in the other sense, the ink application bar 31 can be pressed against the anilox roller 1 if this is necessary.
