Definitions

  • the invention relates to rinse inking units on an ink fountain roller of a rotary printing press.
  • the contact of the ink compartment plates with the rapidly moving surface of the anilox roller inevitably leads to scoring on the surface of the anilox roller and wear of the ink compartment plates.
  • the color compartment sheets are initially automatically readjusted using the provided pressure means, but ultimately have to be replaced.
  • the problem of scoring on the surface of the anilox roller weighs more heavily here. This reduces the quality of the color distribution, in particular when the format to be printed is changed from, for example, 1/4 wide printing to 1/2 wide printing or panoramic printing.
  • the speed of rotation of the anilox roller is limited by the contact of the ink compartment plates with the anilox roller, since the wear of both parts increases enormously with the higher peripheral speed of the anilox roller.
  • the invention has for its object to provide a rinsing inking unit in which the ink compartment plates have no contact with the ink fountain roller.
  • the advantages of the invention are as follows, no wear of the ink fountain roller and ink compartment sheets, especially in their sealing area, no temperature problems due to frictional heating of the ink compartment sheets. Highest peripheral speeds of the anilox roller are possible. Post-doctoring devices can be omitted. Guiding and adjusting devices for the color compartment sheets can also be omitted.
  • the device according to the invention is suitable for both oil-based and water-based paints. A reversal of the direction of rotation is possible.
  • An ink fountain roller 1 designed as anilox roller has in the axial direction a plurality (for example 4) of rinsing inking units 2 (for example 1/4 wide each) which are arranged next to one another and preferably from below on a jacket surface 3 of the Ink fountain roller 1 are employed without touching them with their ink compartment plates.
  • Each flushing inking unit 2 has a housing 4, consisting of a base plate 6, in each case a front and rear side wall 7; 8 and in each case a left and right side cover 9; 11.
  • On the front and rear side walls 7, 8 is in each case by means of a clamping piece 12; 13 a doctor blade 14; 16 clamped, which by means of a front doctor edge 17; 18 is employed on the anilox roller 1.
  • the anilox roller 1 forms a closed ink space 19 with the flushing inking unit housing, which only has a small gap s (approx. 0.2-0.5 mm) between the covers 9, 11 and the jacket surface 3.
  • a paint application channel 23 is provided within the flushing inking unit housing 2 and extends in the axial direction almost over the entire length of the flushing inking unit housing 2.
  • the paint application channel 23 consists of a cut tube. With an upper opening 24, the ink application channel 23 is set against the surface 3 of the anilox roller 1.
  • a left and right inking sheet 24, 26 is provided, which is adapted to the circumference of the ink fountain roller 1 and is arranged at a small distance (e.g. 0.2 mm) from the latter.
  • the ink application channel 23 forms an almost closed ink space 29 with the anilox roller 1 and the ink compartment plates 24, 26.
  • an ink supply channel 32 is provided, which has the same length has the same as the ink application channel 23.
  • the ink supply channel 32 is formed from a part of the base plate 6, two side walls 33, 34 and the base 27 of the ink application channel 23.
  • ink supply bores 28 are provided in the axial direction over the length of the ink application channel 23, the opening cross section of which increases from the center outwards.
  • An ink supply connection 31 is also arranged in the middle of the flushing ink unit housing 4. The arrangement of the ink supply bores 28 prevents a drop in pressure in the ink application channel 23.
  • the printing ink is pumped under a slight excess pressure (approx. 0.5-1 bar) via the ink supply connection 31 and the ink supply channel 32 and the ink supply holes into the ink application channel 23.
  • the anilox roller 1 is set in rotation and colored by the ink application channel 23.
  • the small distance a between the ink compartment plates 24, 26 allows the printing ink, which is under a slight overprint, to emerge from the sides in small amounts, depending on the viscosity of the ink used.
  • the emerging paint now enters the unpressurized space 19 and can flow through ink drain holes 36, 37 in the base plate 6 and be fed to a color reservoir.
  • a suction device (not shown) connected to the paint drain holes 36, 37 can further intensify the sealing process if the space 19 is thereby subjected to a slight negative pressure.
  • the shape of the paint application channel 23 was selected as a simple embodiment. However, other paint application strips or channels are also conceivable. For example, a further exemplary embodiment, corresponding to the outer flushing inking unit housing 2, also have doctor blades which have contact with the anilox roller 1.
  • 23 profile bodies can be provided in the paint application groove, which favor a circulation of the color in the paint application groove 23.
  • 23 paint extraction holes can be provided on the paint application channel, by means of which e.g. a quantity of ink enriched with air bubbles is aspirated.
  • two side plates 9, 11 and color compartment plates 24, 26 are provided on the rinsing inking unit ends; it is hereby also proposed to provide additional side covers if necessary, so that three or more covers are also conceivable on each side.
