Definitions

  • the invention relates to a device for cleaning an inking unit an offset printing machine with a separately driven ink fountain roller immersed in an ink fountain, an ink lifter roller and a downstream ink take-off roller of an inking unit roller train.
  • An inking unit of this type is known from DE-AS 2 316 635, at who applied the cleaning liquid to a first inking roller is and by a second ink roller, the mixture of ink and Cleaning liquid scraped off.
  • DE 3 606 006 A1 describes a device for cleaning a Inking unit known in which the application of the cleaning liquid depending on the ink layer thickness on the rollers / cylinders taking into account the strand length. At least two Feeds for the cleaning liquid are the primary and Assigned secondary strand of the inking unit.
  • An inking unit for offset printing machines which as a film inking unit or lifter inking unit can be operated, is from the DE 2 703 424 B1 known.
  • the ink lifter roller is in lift operation between the ink fountain roller and the assigned ink removal roller Single drum roller pivoted.
  • the Ink take-up roller coupled to the ink fountain roller and the ink lifter roller serves as a rider roller.
  • About an eccentric bearing Ink pick-up roller can be transferred to both positions.
  • a disadvantage of the Execution according to DE 3 606 006 is that the ink fountain roller is not compatible with the rest of the single drum roller can be cleaned and therefore manually by the operator must be cleaned.
  • a device for cleaning an inking unit is known from US Pat. No. 4,643,092 an ink fountain roller, an ink lifter roller and an ink take-off roller known.
  • Ink fountain roller By switching on an additional roller in the cleaning operation Ink fountain roller in contact with the ink lifter roller via this roller.
  • the Ink lifter roller is also in contact with the ink take-off roller, so that everyone called rollers form a single drum roller.
  • JP-A-57120443 Patent Abstracts of Japan, Vol. 6, No. 213 (M-167)
  • M-167 Patent Abstracts of Japan, Vol. 6, No. 213 (M-167)
  • the Ink lifter roller carrying lever moves spring-loaded, such that the Ink lifter roller is in contact with the ink feed roller and the ink take-off roller.
  • the object of the invention is to develop a solution that a simultaneous Cleaning of ink fountain roller and the downstream single drum roller permitted.
  • a lifter inking unit arranged, of which an ink fountain roller 1 and an ink take-off roller 3rd are shown.
  • the ink take-off roller 3 is arranged downstream of a single drum roller at least one feed device for the cleaning liquid and one Doctor tray as receiving device for the ink / cleaning liquid mixture assigned (not shown).
  • an ink fountain roller 2 is arranged intermittently.
  • the inking roller 2 is rotatably arranged on each end of a lever 7.
  • Lever 7 is rotatably fixed with an eccentric bearing 4 and carries at the free end a cam roller 6.
  • the cam roller 6 is one Control device 5, e.g. assigned as a cam.
  • the Eccentric bearing 4 is connected via an articulated coupling 9 Working cylinder 8 connected.
  • the mode of operation is as follows: after a print job has ended, after the end of the shift or with an unfavorable ink / dampening solution ratio it is necessary to clean the inking unit.
  • the ink fountain roller 1 is driven by its separate drive decoupled.
  • the inking roller 2 is in constant at its circumference Contact with the ink fountain roller 1 and the ink removal roller 3 brought (cleaning position).
  • the working cylinder 8 is from actuated from a control station and moved over the coupling 9 and Eccentric 4 the lever 7 so that the inking roller 2 in Cleaning position is spent.
  • the intermittent movement the inking roller 2 is exposed by the cam roller 6 is separated from the control device 5 (see dashed lines Presentation).
  • the ink fountain roller 1 and ink fountain roller 2 are driven by friction on the downstream single drum roller.
  • the Feeding device for the cleaning liquid is activated and the paint / cleaning fluid mixture is from a downstream arranged receiving device, e.g. a squeegee tray from which relevant inking unit roller doctored.
  • the ink fountain roller 1 remains with her Drive coupled by this with the drive for the ink roller 3 and the downstream inking roller synchronously in the Cleaning position operated at the same peripheral speed becomes.
  • the ink fountain roller 1 is also used for Ink take-up roller 3 different peripheral speed in the Cleaning position driven. The slip that occurs increases the cleaning effect on the Roller surface.
