Definitions

  • the invention relates to a method and an apparatus for Feeding ink from a color dispenser into one Ink fountain with an ink fountain roller and ink metering elements in an inking unit of a printing press.
  • a device of this type is known from DE-G 1 944 832, at the one ink donor device slidable on the ink fountain roller is arranged and the color from the ink dispenser below Pressure pressed directly onto the outer surface of the ink fountain roller becomes. A note on the disposal of the residual paint from the paint box cannot be seen.
  • a method for determining the consumption of printing ink is over known from DE 3 835 221 C2.
  • Calculation of the expected amount of paint the color consumption is continuously calculated and the used one
  • the amount of paint is added to the amount of ink in the paint box continuously compared.
  • a refill is still available standing amount of color during the execution of the print job will lapse.
  • the solution is relatively complex because there are many Data must be recorded and processed.
  • From DE-A 23 24 462 is a device for maintaining a predetermined level of the ink in a color box known.
  • the device has i.a. a counter that shows the number of times ink is printed was fed to the ink fountain.
  • the object of the invention is to develop a solution to the Cleaning effort of paint remaining in the paint box at the end of a print job or during a planned color change reduced. This is solved by the characteristic part of the Claims 1 and 5.
  • the invention has the advantage that in the ink fountain from the start of printing there is always a minimal supply of color, which is indicated by a controlled dosing of the color from the ink dispenser is approximately constant.
  • the minimum color reserve of the buffer memory is much smaller in quantity than the conventional amount Color supply of a color box. The amount must just be enough to to avoid tearing off the ink film on the ink fountain roller.
  • the solution according to the invention allows optimal use of color fed into the paint box and reduces the problem of Disposal of residual paint remaining in the paint box is noticeable.
  • the ink is supplied from a paint dispenser to the Buffer memory directly to the color-consuming color metering elements.
  • the present solution is suitable for both web and sheetfed offset presses.
  • 1 is a sheet-fed rotary printing press in series with a feeder 2, two printing units 1, each with an inking unit 4 and a boom 3 shown.
  • 2 is essentially an ink fountain 5 and an associated ink fountain roller 7 of the inking unit 4 shown.
  • the ink fountain 5 has an ink fountain floor 6, the one below, centered on the ink fountain roller 7 ink metering elements 8, preferably color slides, are assigned.
  • the color dosing elements 8 extend over the entire length of the ink fountain roller 7.
  • Im Ink fountain 5 is in the immediate vicinity of the ink metering elements 8 a buffer memory between the ink fountain base 6 and the ink fountain roller 7 provided for the formation of the minimum color supply.
  • a color dispenser is used to form the buffer store 9 13 protruding into the ink fountain 5 with its outlet opening arranged.
  • a sensor 12 is arranged which is connected to the color donor device 13 is connected in terms of circuitry.
  • the sensor 12 controls the filling level of the buffer memory 9.
  • the ink dispenser 13 is parallel to the ink fountain roller 7 within the ink fountain 5 movable (not shown). This can be done, for example, using a Realize a traverse or a portal with a corresponding linear guide. The traverse or the portal is preferably at the same time vertically movable with the paint dispenser.
  • the paint dispenser 13 is with a preset counter 11 for the number of to processing bow coupled in terms of circuitry.
  • the preset counter 11 can be integrated in the area of the feeder 2 or in a control center be arranged.
  • the mode of operation is as follows: In the ink fountain 5 from the Color dispenser 13 under pressure offset printing ink in the Buffer memory 9 fed until there is a minimal supply of color forms. According to the color consumption is in the buffer memory 9 again added color from the ink dispenser 13. To the ink donor device 13 becomes parallel to the ink fountain roller 7 to the required, assigned to the ink metering elements 8, Position driven. In the present example, at the positions 8.2; 8.3; 8.5; 8.6 and 8.9 more color added (Fig. 3, 4) than in the remaining positions of the color metering elements 8.
  • the preselection counter 11 is based on the amount of substrate to be processed adjustable e.g. according to the criteria of time or number of sheets.
