Definitions

  • the invention relates to an inking unit for a Rotary printing machine according to the preamble of Claim 1.
  • EP 06 63 293 A1 (according to Art 54 (3) EPC) and the EP 04 99 382 A1 show that can be set on an anilox roller Chamber squeegee.
  • the chambered doctor blades are on a carrier for Starting and stopping pivoted.
  • the invention has for its object an inking unit with chamber doctor blade for inking a roller z.
  • the invention is particularly advantageous achieved that always the same doctor chambers in Adjustments can be used, though the diameter of the cylinders to be colored is Can change order to order, but also from machine to machine. It would only be the side sealing lips exchange.
  • an anilox roller or Gravure cylinder (can be rasterized) is one a total of 7 chamber doctor blade device against an adjustable, frame-fixed stop 5 employable.
  • the stop 5 is in a horizontal Plane and perpendicular to a rotation axis 8 of the Cylinder 6 adjustable; as well as the Chamber doctor device 7.
  • the chamber doctor device 7 consists of a to the axis of rotation 8 of the Cylinder 6 support body 9 extending axially parallel, which one running parallel to the axis of rotation 8 and open channel 10 in the direction of the forme cylinder 6 has a length l.
  • the carrier body 9 is each with one end: striking plate 11, 12 locked.
  • doctor blades 16, 17 are arranged, which each face the cylinder 6 Edge in the direction parallel to the axis of rotation 8 rest on the outer surface 18 of the cylinder 6.
  • the doctor blade 16 is designed as a closing doctor blade and is of one on the lateral surface 18 of the in FIG Clockwise rotating cylinder 6, axis-parallel line happens first.
  • the doctor blade 17 is executed as a working squeegee.
  • Both doctor blades 16, 17 are each by a known doctor holder 19, 21, z. B. one extending in the axial direction strip-shaped terminal strip held.
  • the channel 10 in A doctor chamber forms a connection with the doctor blades 16, 17 22, which via one or more feed lines 25, the e.g. B.
  • the cylinder 6 has a bale length m by an amount of two same partial lengths x is greater than the length l of the Chamber doctor blade device 7.
  • the carrier body 9 of the Chamber doctor device 7 is pivotable on one first end 23 of one or more pivot arms 24 stored.
  • a second end 26 of the pivot arms 24 is in a side frame fixed axis 27 stored so that the entire chamber doctor device 7th to and on the cylinder 6 via the stop 5 is pivotable.
  • the entire doctor blade device 7 is in the axis-parallel direction to cylinder 6 arranged changeable.
  • a trough 28 is arranged below the cylinder 6, which may be from the doctor blade device 7 running gravure ink fields and over a drain 29 and a pipe 31 symbolically shown and designated a total of 32 Feeder is fed, via which new Gravure ink is added, if necessary cooled and the mixed gravure ink via a pipe 33 the Doctor chamber 22 is fed back (only in Fig. 1st shown).
  • cylinder 6 Above cylinder 6 is a cylinder 6 pressing, rotatable impression 34 arranged, which on both sides via its pivot 37, 38 in rocker 39, 41 stored and each with a side frame fixed and height-adjustable sled, not shown is positively and positively connected.
  • the bale length m of the cylinder 6 can, for. B. between two and three meters.
  • the respective partial length x can e.g. B. are each 50 mm.
  • doctor chamber 22 in spaced axially parallel to each other Arrange spray nozzles for spraying gravure ink.
  • This can e.g. B. by means of in the doctor blade chamber 22nd located tube and closed at its ends happen, which over several supply lines with Gravure ink is applied and which by in bores extending axially. Excess or scraped gravure ink can over in the axially parallel direction in the doctor blade 16 - Squeegee - drilled holes in the Trough 28 and the feed device 32 returned become.
  • the bale length m of the cylinder 6 can be between two and three meters.
  • the respective front Partial length x can e.g. B. each up to 50 mm (less pressure Space), as well as the distance y (not between two chamber doctor blade devices, provided it is multi-part chamber doctor blade devices deals with different printing inks.
