Definitions

  • the invention relates to a convertible lifter / film inking unit with an ink fountain roller 1 arranged on an ink fountain, an inking roller 4 supplying ink to the downstream ink rollers, a lifting roller 2 which can be adjusted to the ink fountain roller 1 and can be swung away therefrom, the pivot mechanism of which can be switched off in film operation, and an additional roller 3 with a hard surface.
  • an inking unit for offset printing presses of the type specified above is known.
  • a lifter roller is pivoted between an ink fountain roller arranged on an ink fountain and an ink take-off roller as an additional roller.
  • the said ink take-off roller is placed directly on the ink fountain roller, so that it now works as a film roller, while the lifting roller remains in permanent contact with the ink take-off roller, so that it acts as a rider roller.
  • the ink take-off rollers or film rollers used in film inking units which are attached to the ink fountain roller for ink take-off, have a structured surface.
  • the object of the invention is to design a convertible inking unit of the type mentioned at the outset so that the lifting roller can interact with the ink fountain roller and an inking roller if necessary without a structured surface in the lifting operation, an additional roller with such a surface should be usable in film operation a minimum of rollers.
  • An advantage of the design of the convertible lifter / film inking unit according to the invention lies in the possibility of having the lifter roller set up against an inking unit roller, for example an ink fountain pen with a smooth surface, so that signs of wear can be prevented, while in film operation the ink fountain roller as an additional roller Film roller with a textured surface is adjustable.
  • Another advantage lies in the simple adjustment of the film roller to the lifting roller, since it is not necessary to readjust a lifting roller that works as a film rider roller.
  • the film roller bearing is not covered by the jack levers.
  • a convertible lifter / film inking unit is shown schematically, which is used in a known manner with a number of ink transfer rollers and ink drivers (not shown) for inking a plate cylinder (not shown).
  • Said part of the convertible inking unit comprises a driven ink fountain roller 1, a lifting roller 2, an additional or ink take-off roller 3 and a driven inking roller 4, which can be designed as an ink grater.
  • the lifting roller 2 can be pivoted by a schematically illustrated pivot mechanism 5, so that it can assume the position shown in solid lines in the drawing and the dash-dotted position 2 '.
  • the additional roller 3 can be pivoted by a pivot mechanism 6 between the position shown in solid lines and a position 3 'shown in broken lines.
  • other mechanical, pneumatic or hydraulic actuating devices can be used to switch the additional roller 3 on and off.
  • the ink fountain roller 1 and the rollers 3 and 4 have hard, for example metallic surfaces, while the surface of the, for example, rubber-coated lifting roller 2 is soft.
  • the lifting roller 2 When the inking unit operates in the lifting mode, the lifting roller 2 is pivoted back and forth between the ink fountain roller 1 and the inking unit roller 4 by the pivot mechanism 5.
  • the inking roller 4 can act as a grater and have a smooth surface, so that the soft surface of the lifting roller 2 is protected when the lifting roller 2 is placed on the inking roller 4. If the inking unit operates in the lifting mode described above, the film roller 3 is switched off from the ink fountain roller 1 and the lifting roller 2 and assumes the position shown at 3 '.
  • the lifting roller 2 remains in contact with the inking unit roller 4, the pivoting mechanism 5 being stopped. Furthermore, the additional roller 3 is placed against the ink fountain roller 1 and the ink lifter roller 2, an ink transfer gap being set between the latter and the additional roller 3 to bridge speed differences due to the slower running ink fountain roller 1, the width of which depends on the speed difference and the desired ink transfer . With this roller configuration, the additional roller 3 now takes off ink from the ink fountain roller 1 and transfers it via the lifting roller 2 to the ink transfer roller or inking roller 4.
  • Ink transfer between the ink fountain roller 1 and the additional roller 3 can be structured, for example, the metallic surface of the inking roller 3.
  • the jack roller 2 and the additional roller 3 are driven by friction, so they do not need their own drive.
  • the roller configuration shown in the drawing enables a compact construction, the pivoting or adjusting mechanisms used for the lifting roller 2 and the additional roller 3 being able to be set in locally suitable positions. It is essential that the arrangement of the additional roller 3 approximately above or approximately below the ink fountain roller 1 and the inking roller 4 approximately at the level of the lifting roller 2 between the additional roller 3 and the inking roller 4, so that, for. B. with an expansion of the lifter roller 2 by heating in film operation, the additional roller 3 is moved approximately tangentially to the ink fountain roller 1, so that no significant gap changes occur between these rollers.
  • a conventional film inking unit can be switched to a conventional jack inking unit by switching off the additional roller 3 and switching on the swivel mechanism 5.
