Definitions

  • the invention relates to an inking unit for rotary printing presses, in which the ink can be fed from at least one applicator roller from an ink fountain roller via an ink transport line which consists of a plurality of inking unit rollers arranged in series in the ink transport direction.
  • Such an inking unit is known from DE-AS 27 03 425, Fig. L.
  • the invention has for its object to develop such an inking unit so that a change in the thickness range of the ink film to be delivered to the plate cylinder can be achieved without changing the ink knife setting.
  • the inking unit shown comprises an ink fountain roller 1 driven at low surface speed, against which an ink knife 2 can be adjusted more or less strongly.
  • the ink in the setting according to FIG. 2 is transferred from the ink fountain roller 1 via five inking rollers 3 to 7 to two applicator rollers 8, 9, which in turn deliver the ink to a plate on a plate cylinder 10.
  • the inking rollers 3, 5 and 7 expediently have a metallic, hard surface and are designed as a grater, that is to say they are arranged so as to change in the longitudinal direction.
  • pivoted levers 13, 14 In front of the two ends of the inking unit rollers 3 and 7 mounted on inking unit side walls, not shown are pivoted levers 13, 14 about axles aligned with their axes, 12, between the other ends of which the inking rollers 4 and 6 are rotatably supported with their axles 15, 16.
  • the inking unit rollers 3, 5 and 7 are also expediently driven, at the same surface speed as the plate cylinder 10, while the inking unit rollers 4 and 6 and the application rollers 8 and 9 are carried along by friction.
  • Hydraulic cylinders 17, 18 with adjusting rods 19, 20, which are articulated on the levers 13, 14, are used to actuate the levers 13, 14.
  • levers 25, 26 are pivotably mounted by means of axle journals 23, 24, which are aligned with the axes of the additional inking unit rollers 21, 22.
  • Axle journals 27 of a further additional inking unit roller 28 are rotatably mounted on the levers 25, while the levers 26 serve to support the axle journals 29 of an additional inking unit roller 30.
  • the levers 25, 26 are in turn pivotable by means of hydraulic cylinders 31, 32 and adjusting rods 33, 34.
  • the ink is guided to the applicator rollers 8 and 9 via the inking unit rollers 3 to 7 which are connected to one another by the dash-dot line A.
  • the application rollers 8, 9 are fed a relatively thick ink film.
  • the inking unit can therefore be used in this setting for DiLitho printing. This setting can also be used for offset printing if large contiguous areas are to be printed.
  • the ink film thickness on the inking rollers 8 are obtained.
  • the ink knife 2 thus only serves to fine-tune the ink film thickness within the thickness range preset by changing the number of rollers of the ink transport strand. It can thus be prevented that the printer tries to open the ink knife 2 to such an extent that the ink film thickness on the inking roller 3 rotating at a higher speed becomes so great that the ink squirts off.
  • inking unit rollers 4 and 6 can be switched off from the inking unit roller 5 in the exemplary embodiment, there is also the possibility of setting an intermediate position for a medium ink film thickness, for example by virtue of the fact that the inking unit roller 6 and the additional inking unit roller 30 assume the position shown in FIG. 1 while the Inking roller 4 and the additional inking roller 28 are left in the position shown in Fig. 2.
  • the invention is not restricted to the exemplary embodiment shown. Instead of interrupting the short ink transport strand at two points, it can also be interrupted at one or three points. There is also the possibility of switching on either one or more than two rollers, which are then to be arranged in series, in order to bridge the interruption points of the short ink transport strand.
