Definitions

  • a color division device between different color-promoting areas of ink rollers of printing presses is known e.g. B. become known from DE-C-1 961 033.
  • this ink separation device has the disadvantage that relatively wide ink-free areas are formed on the circumferences of the rollers. These pressure-free spaces continue through the following ink transfer rollers down to the print carrier.
  • DE-A-3 135 711 shows a flushing inking unit with an anilox roller for a rotary printing press according to the preamble of claim 1. It consists of an ink fountain whose storage space consists of a rear wall of an application bar on the job bar arranged doctor blade and doctor blade and part of the jacket of the anilox roller. However, no color compartment devices for different-colored printing inks are provided.
  • an ink compartment device for a conventional ink fountain is known, in which the ink fountain roller is not rasterized and rotates slowly.
  • the ink fountain roller sealant is made of a soft, resilient material held between two thin sides.
  • An automatic adjustment of the color compartment is not provided.
  • the side panels must be loosened.
  • This ink compartment device cannot be used as a seal on high-speed ink fountain rollers, in particular anilox rollers.
  • the invention has for its object to provide an ink separation device between different ink-promoting areas of ink rollers of printing presses with a very narrow sealing surface between the ink separation device and ink roller.
  • the advantages that can be achieved with the invention are, in particular, that no gaseous medium is required for sealing.
  • the ink separation device can be made very thin, so that, despite the ink plate being buried in the inking roller, only negligible disturbances in the printed image are noticed when the ink separations are later shifted.
  • the color division device adjusts itself automatically when worn.
  • the ink separation device is suitable for both oil-based and water-based flexo inks and other low-viscosity printing inks. It can be used with ink rollers with a smooth as well as with a rastered surface. It is easy to change the sheet-shaped color compartment sheets, they are also very easy and inexpensive to manufacture. Even with a high peripheral speed of the inking roller, the ink compartment plates heat up only slightly, so that special cooling of the ink compartment plates is not necessary.
  • the ink division device between areas of ink rollers of printing machines which promote different colors is described in use in a flushing inking unit known from DE-A-3 135 711.
  • a driven anilox roller 1 is mounted in side frames (not shown).
  • One or more ink application bars 2 are arranged on and off the anilox roller 1.
  • An upper doctor blade 3 and a lower doctor blade 4 are attached to the ink application bars 2.
  • the paint application bar 2 is provided with a recess 7 opposite the outer surface 6 and extending over the entire length of the paint application bar 2. This recess 7 is connected via a through hole 8 to an ink supply device.
  • a face plate 12 is screwed onto the end face 11 of each paint application bar 2.
  • the guide plate 12 is provided with a guide recess 14.
  • the guide recess 14 lies opposite the end face 9 or 11 of the paint application bar 2.
  • the guide recess 14 is closed at the top and bottom and is dimensioned such that a thin paint compartment plate 17 can be pushed into it and is guided through it.
  • the color compartment sheet 17 according to the invention is designed so that it can be easily pushed back and forth in the guide recess 14 and has a width 16 of z. B. 65 mm and a length 20 of z. B. 45 mm.
  • a second end face 21 of the paint compartment plate 17 is preferably not curved.
  • leaf springs 22, 23 ensure that the curved end surfaces 19 of the ink compartment plates 17 are always pressed against the outer surface 6 of the anilox roller 1.
  • the ink compartment plates 17 rest on the end faces 9 of the doctor blades 3 and doctor blades 4.
  • the thickness of the color compartment plates 17 can be between 0.1 mm and several millimeters thick.
  • the ink compartment plate 17 is thick at an end 24 facing the anilox roller 1 over its entire width between 0.03 and 0.3 mm. If a guide part 26 of the paint compartment plates 17 is thicker than the thickness 27 according to the invention of the front end 24 between 0.03 and 0.3 mm, a cut, e.g. B. be provided at a depth 18 of 3 mm, as shown in Figures 5 and 6. It is essential to the invention that the sealing surface 19 of the paint compartment plates 17 is made as narrow as possible.
