Definitions

  • the invention relates to a doctor blade device for a rinse inking unit a rotary printing press consisting of a through a profile strip formed with a groove-shaped recess Doctor knife carrier, on the approximately roof-shaped and parallel two mutually adjustable on an inking or anilox roller Doctor blades are attached, which together with the inking roller, the channel-shaped recess of the doctor blade carrier and at the end of this provided sealing means delimit an ink chamber from lines for feeding and discharging of paint into and out of the paint chamber, and from adjusting devices for pressing the doctor blade holder onto the Inking roller.
  • the object of the invention is therefore a doctor blade device to create the type specified, in which the ends a good sealant provided on the doctor blade carrier Ensure that the ink chamber is sealed against leaking paint.
  • this object is achieved with a doctor device of the generic type solved in that the trough-shaped Recess with a middle, preferably up to End portions extending middle part forming a main chamber and end-side side panels forming side chambers which is connected to the main chamber by throttling gaps are that in the main chamber the paint supply line opens and that the side parts with the color-dissipating Connected lines and provided with ventilation holes are.
  • the doctor device can be by Introducing the paint into the main chamber of the paint chamber the desired one Maintain overpressure in color. From the The color enters the main chamber through the throttle column unpressurized secondary chambers, so that the end of the doctor blade carrier provided seals the ink chamber laterally are able to seal well, since the seals do not pass underneath Pressurized color can be applied.
  • the main chamber and the secondary chambers are expedient by radial partitions of the groove-shaped recess from each other separated, the edges of which are curved in the shape of a circular arc limit the throttle gap with the anilox roller.
  • the partitions can be formed by rib-like elevations. Farther can the partition walls by curved wall parts pass into the main chamber. Conveniently, the outer sides of the partition walls on radial planes.
  • each of the partitions with a coating is made of plastic covering the edges of the partitions dominates and thus the squeegee throttle gap limited.
  • the secondary chambers can be in the longitudinal section of the doctor blade carrier have an L-shaped cross section. Expediently extends one each by an L-leg of the secondary chambers formed space up to the main chamber.
  • doctor blades are subject to unavoidable wear, so that with their increasing wear the radial partitions with its arcuate curved and the choke column bordering edges approximate to the anilox roller and the width of the throttle gap undesirably decreases.
  • the essentially impassable connection of the partitions with the inking unit frame carrying the squeegee device be accomplished by different means.
  • the partitions through resilient tongues or webs with the profile strip are connected so that they correspond to the progressive Dodge wear of the doctor blades to the rear can.
  • the partitions can each have rods on one stop the inking box be supported.
  • the rods can pass through special holes or openings be led out of the profile bar. However, it is useful the rods through the ventilation holes from the profile strip lead out, which are present anyway, so that no special openings or openings for the rods must be provided.
  • the stop is expedient by an actuating device adjustable, so that there is also the possibility adjust the width of the throttle gap.
  • the inking unit 1 which is movable in the usual way on the pressure cylinder block, which is also designed as a slide is stored in the usual and therefore not described in detail
  • One side of the anilox roller 2 stored.
  • the inking unit 1 On the inking unit 1 are the parallel links around the hinge axes 3, 4 5, 6 pivotally mounted. The upper ends of the parallel link 5, 6 are pivotable about the joint axes 7, 8 connected to the support 9 forming a coupling.
  • the carrier 9 is integrally formed with the doctor blade 10.
  • the squeegee 10 is by screws provided with handwheels 11 with the doctor blade carrier connected.
  • the piston rod 12 of a pneumatic cylinder 13 articulated, which in turn via a support piece 14 articulated by the joint 15 to the inking unit 1 is.
  • the hinge axes 4 of the parallel link 6 are with an eccentric adjustment 4 'provided, due to which the pivot axis the parallel link 6 can be raised and lowered.
  • the parallel link 5, 6 each of the two anilox roller 2 storing Inking units can double to increase stability be executed.
  • the doctor blade carrier 11 consists of a profile strip, the 1 can be seen.
  • the bar of the doctor blade holder 11 is with a forming the interior of the ink chamber Channel 20 provided. This channel flows into the lower middle
  • the area, as can be seen from FIG. 3, is the printing ink feeding bore 21.
  • the end faces 26, 27 of the gutter edges are roof-shaped in opposite directions beveled. On these end faces 26, 27 are through Clamping brackets 28, 29 the doctor blades 30, 31 in the usual and therefore attached not described in more detail.
  • Seals 33, 34 are on the sides of the doctor blade carrier 11 arranged, the ink chamber interior 20 opposite the anilox roller 2 seal. To hold these seals are with the side end faces of the bar of the doctor blade holder Screwed lid 35, 36.
  • the interior of the ink chamber is cross-sectionally on its sides provided approximately L-shaped chambers 38, 39. These chambers are from the middle part of the interior of the ink chamber through intermediate walls 40, 41 divided, against the anilox roller 2 bounding edges delimiting circularly curved gaps 42, 43. Starting from the edges 42, 43 are curved wall parts 44, 45 in the central main part of the interior of the ink chamber about.
  • the side chambers 38, 39 are through the throttling gaps 42, 43 connected to the central part of the interior of the ink chamber.
  • the wall parts 40, 41 thus form, as it were, weirs, through which in the middle part of the interior of the ink chamber the feed hole 21 introduced paint under pressure reduction enters the unpressurized lateral chambers 38, 39.
  • open vent holes 24, 25 into these To ensure the depressurization of the chambers 38, 39, open vent holes 24, 25 into these.
  • the outer sides of the walls 40, 41 are covered with coverings 48, 49 made of plastic, which limit the gaps 42, 43 Slightly protrude edges so that there is a metallic contact the edges with the anilox roller 2 are excluded.
