Definitions

  • the invention relates to an ink fountain for printing machines according to the preamble of the first claim.
  • the ink fountain side parts are first set against the ink fountain roller and there is rough regulation of the ink metering device, e.g. B. the color meter or the color metering elements with the machine stopped.
  • the inking unit see DE patent application Az. F 10648, At .: 23.06.51
  • the ink fountain see DE utility model 1 675 338
  • parts of the ink fountain DE- OS 3 325 005, US-A-2 268 594
  • the color metering device DE utility model 1 891 449
  • thermal expansions against one another are also brought to a limited extent, so that the thermal stresses in the ink fountain, the dosing means and the ink fountain roller partially cancel each other out.
  • Reduced tension due to thermal expansion leads to fewer ink fluctuations on the ink fountain roller, which can be more easily adjusted by the printer.
  • the thermal insulation on the bottom and back of the ink fountain reduces the annoying heating of these parts, which are particularly exposed to the hot air flow from the sheet guiding devices of the machine.
  • the side of the ink fountain facing the ink fountain roller is only slightly affected by the warm machine air, depending on the installation conditions. This part of the ink fountain is then at a lower temperature than the rest of the ink fountain body. To equalize the temperature, the hot air flow is directed by fans and baffles at the ink fountain edge on the metering side. This reduces the temperature gradient to less than 1 degree. Due to this low temperature gradient, correspondingly lower tensions occur in the ink fountain lower part, the metering elements and the ink fountain roller, i.e. H. the set color gap is subject to fewer fluctuations in the thickness, which can be more easily adjusted by the printer without the need for temperature control or additional heating.
  • the invention also brings about a temperature control of the printing ink and a stabilization of the ink / fountain solution emulsion. Since the air from the sheet guiding systems of the machine heats up after a short period of operation, the ink is heated by blowing on the ink fountain roller. Because of this temperature control, the printing ink shows a much more uniform viscosity behavior in the warm-up phase of the machine, which is also important for constant Color guide is.
  • the ink fountain 2 shown in FIGS. 1 and 2 is deposited on both sides on supports which are connected by a cross member 5 and can be inserted into the machine as a whole via rails of the machine frame (not shown here). This operating position is defined by stops, not shown, which end the insertion movement.
  • the ink fountain 2 is arranged such that it can be pivoted away from the ink fountain roller 1 via a pivot point, not shown.
  • the ink fountain 2 is delimited on the two end faces in a known manner by in each case one ink fountain side part, the end face of which is provided with a recess corresponding to the surface curvature of the ink fountain roller 1. This will cause the color to leak in the Contacting area prevented.
  • the pivoting movement of the ink fountain 2 to the ink fountain roller 1 takes place via a toggle lever (not shown) and a swivel gear, also in a known manner.
  • the underside of the ink fountain fuselage is provided with thermal insulation 6.
  • a middle region (1/2) of the side of the ink fountain body facing the ink fountain roller 1 is acted upon by a warm air flow during the operating time of the printing press, which is increased by fans 3.
  • the fans 3 are in the vicinity of a heat source arising in the operating time in the printing press, e.g. B. arranged below the ink fountain 2 above a sheet guide drum, so that the hot air flow from this drum acts on this area of the ink fountain 2.
  • the fans 3 are surrounded by a guide device 4 such that the hot air is said middle area comes exactly into the gap between the ink fountain roller 1 and the side of the ink fountain body facing this. In this way, all essential parts of the ink fountain 2 are washed around evenly.
  • thermal insulation 6 As insulation material against the flow of warm air, for example, three mm thick styrofoam (registered trademark) with aluminum lamination is suitable as thermal insulation 6.
  • FIGS. 1 and 2 The air flow is illustrated by arrows in FIGS. 1 and 2, while in FIG. 1 it is also indicated that the guiding device 4 encloses the traverse 5 and thereby leaves a gap to the ink fountain body between the guiding device and the traverse, the guiding device 4 being by means of a screw is attached to the traverse.
