Definitions

  • the invention relates to an inking unit for a rotary printing press according to the preamble of claim 1.
  • the invention has for its object to provide an inking unit with a doctor blade for inking a roller z. B. to create a screened roller or gravure cylinder for a rotary printing press.
  • the invention achieves the advantage in particular that the same doctor blade chambers can always be used in adjusting devices, although the diameter of the cylinders to be inked can change from job to job, but also from machine to machine. Only the side sealing lips would have to be replaced.
  • a chamber doctor device designated overall 7 is adjustable against an adjustable, frame-fixed stop 5.
  • the stop 5 is adjustable in a horizontal plane and at right angles to an axis of rotation 8 of the cylinder 6; likewise the chamber doctor device 7.
  • the chamber doctor device 7 consists of a support body 9 which extends axially parallel to the axis of rotation 8 of the cylinder 6 and which has a channel 10 with a length l which runs parallel to the axis of rotation 8 and is open in the direction of the forme cylinder 6.
  • the end face of the carrier body 9 is closed in each case with a: striking plate 11, 12.
  • Squeegees 16, 17 are each arranged on free legs 13, 14 of the carrier body 9, each of which rests with its edge facing the cylinder 6 in the axis-parallel direction to the axis of rotation 8 on the lateral surface 18 of the cylinder 6.
  • the doctor blade 16 is designed as a closing doctor blade and is first passed by an axially parallel line on the outer surface 18 of the cylinder 6 rotating clockwise according to FIG. 2.
  • the doctor blade 17 is designed as a working doctor blade. Both doctor blades 16, 17 are each by a known doctor holder 19, 21, z. B. held an axially extending strip-shaped terminal block.
  • the channel 10 in connection with the doctor blades 16, 17 forms a doctor chamber 22 which via one or more supply lines 25, the z. B.
  • the cylinder 6 has a bale length m which is two times the same length x greater than the length l of the chamber doctor device 7.
  • the carrier body 9 of the chamber doctor device 7 can be pivoted at a first end 23 of one or more swivel arms 24 be stored.
  • a second end 26 of the swivel arms 24 is mounted in an axle 27 which is fixedly mounted on the side frame, so that the entire chamber doctor device 7 can be swiveled in and out on the cylinder 6 via the stop 5.
  • the entire chambered doctor device 7 is arranged to be changeable in the axis-parallel direction to the cylinder 6.
  • a trough 28 is arranged below the cylinder 6, which collects gravure printing ink running off from the doctor blade device 7 and is fed via a drain 29 and a pipeline 31 to a symbolically represented and overall designated 32 feed device, via which new gravure printing ink is added, if necessary cooled and the mixed gravure ink is fed back into the doctor blade chamber 22 via a pipeline 33 (only in FIG. 1 shown).
  • a rotatable impression roller 34 Arranged above the cylinder 6 is a rotatable impression roller 34 which presses on the cylinder 6 and is mounted on both sides via its axle journals 37, 38 in rockers 39, 41 and is each connected to a side frame-fixed and height-adjustable carriage, not shown, in a force-locking and positive-locking manner.
  • a paper web is printed between impression roller 34 and cylinder 6.
  • the bale length m of the cylinder 6 can, for. B. are between two and three meters.
  • the respective partial length x can e.g. B. are each 50 mm.
  • the bale length m of the cylinder 6 can be between two and three meters.
  • the respective front partial length x can, for. B. each up to 50 mm (pressure-free space), the same distance y (not shown) between two chamber doctor devices, provided that it is multi-part chamber doctor devices with different printing inks.
  • the striking plates 11, 12 and the doctor blade 16 can be made of a color-solvent-insoluble plastic, for. B. consist of glass fiber reinforced plastic.
