Definitions

  • the invention relates to an ink fountain with an automatic ink supply for printing presses.
  • the sheet-like ink supply of the individual printing towers is on sheetfed offset printing machines in a wedge ink fountain that lies along a duct with ink metering elements that can be adjusted in zones.
  • the dosing elements form an inlet gap to the duct, through which the paint application is regulated.
  • the machine's ink fountain is marked with a Color stock filled.
  • Ink supply devices are also known (DE 43 39 939 C2), in which the wedge-shaped ink supply space has been reduced in size and has been designed in a closed design. The ink is supplied to the reduced and closed ink supply room by means of color cartridges.
  • the disadvantage of this device is that there is inadequate or inadequate coloring and the degree of automation is low.
  • an ink fountain is completely dispensed with and an ink rail extending along the ink fountain roller.
  • the color is via ink guide channels arranged in the ink rail onto the surface of the ink fountain roller brought and distributed there on individual sections that have their own pumps.
  • the feed channels are connected to a central distribution chamber via lines.
  • the object of the invention is to provide an automatic ink supply including one needs-based coloring.
  • the invention is explained in more detail below using an exemplary embodiment.
  • the drawing shows an ink fountain with automatic ink supply.
  • a duct roller 1 is assigned a lower part 2 of a known wedge ink fountain, wherein on Lower part 2 ink metering elements 3 for setting a gap in relation to the doctor roller 1 are arranged.
  • an ink fountain insert 4 is placed and between the Lower part 2 and the bottom 7 of the ink fountain insert 4 is for sealing a flat gasket 5 is arranged.
  • the bottom 7 of the ink fountain insert 4 is at least a fastening screw 6 detachably connected to the lower part 2.
  • a color distribution element 8 is firmly connected to the underside 7 of the ink fountain insert 4.
  • the ink distribution element 8 has an end face 9 that is operatively connected to the duct roller 1 on.
  • the face 9 does not touch the duct roller 1, i.e. it there is a small gap.
  • the front side 9 and the color metering elements 3 close in connection with the underside 7 of the Ink box insert 4 a color storage space 10.
  • a Port 11 for the ink supply to the ink supply space 10 is arranged on the color distribution element 8 .
  • the ink supply from Connection 11 to the ink supply space 10 is made via at least one color distribution channel 12, whereby further ink distribution channels 12 can be arranged across the width of the ink fountain.
  • a pressure sensor 13 is arranged in the color distribution channel 12.
  • connection 11 is with a metering valve 14 with a paint supply system 15 connected.
  • the pressure sensor 13 is connected to the metering valve 14 via a pressure switch 16.
  • the pressure in the ink reservoir 10 drops via the pressure sensor 13 and the pressure switch 16 - pressure sensor 13 and pressure switch 16 can also be in one unit be united - a signal is fed to the metering valve 14 and the ink supply space 10 color added again.
  • connection 11 of the color distribution element 8 is removed from the color supply system separated, the fastening screw loosened and the ink fountain insert 4 from the wedge ink fountain removed.
  • the removed unit is now outside the printing press cleanable, whereby the ink storage room is easily accessible.
