Definitions

  • the invention relates to a dampening system according to the preamble of claim 1.
  • DE 43 12 523 A1 describes a dampening unit with an applicator roller which can be set on a forme cylinder for offset printing and an intermediate roller arranged between the latter and an immersion roller immersed in a dampening solution, the intermediate roller and the immersion roller both being shared by the applicator roller and with a later reproducibility thereof previous mutual contact setting can be switched off.
  • the submersible roller driven at different circumferential speeds with slip to the intermediate roller can also be adjustably limited in relation to the intermediate roller in order to improve the metering of the dampening solution in addition to changing its center distance from the intermediate roller, so that the gap or the pressure between the two rollers can be adjusted axially both uniformly and differently.
  • both solutions have in common that, contrary to a compact design, they consist of a relatively large number of bearing levers and that the rollers are not switched on and off partially overlapping by simple, separate and form-fitting functional elements.
  • the invention has for its object to provide a dampening system according to the preamble of claim 1 that is characterized by a compact design and without the addition of alcohol, the formation of a well-metered, homogeneous, both for newspaper and illustration printing suitable dampening solution film.
  • the object is achieved by the characterizing features of claim 1.
  • the common mounting of all dampening rollers in a bearing plate which can be pivoted in the direction of the forme cylinder permits a particularly stable, space-saving construction which can be realized in a particularly advantageous manner by a plate-shaped configuration of the bearing plate and the levers.
  • the adjustment means according to the invention are simple and, in particular, enable an exact, positive-locking adjustment of the dipping roller to the intermediate roller while guaranteeing their mutual separation when the machine is idle for a longer period of time and being re-engaged by taking their previous contact setting by means of only one adjustment operation.
  • the sensitive metering of the dampening solution between the dipping roller and the intermediate roller and a slippery forced drive of all dampening rollers with each other enables the application of a homogeneous dampening solution film that is suitable for both newspaper and illustration printing and is free of alcohol addition to the forme cylinder.
  • the distribution rollers employed on the applicator roller further optimize the dampening process in order to equalize impurities picked up by the printing plate and to further smooth the dampening solution film.
  • Fig. 1 shows a dampening unit placed on a forme cylinder 1 of an offset printing press, in which an applicator roller 2, an intermediate roller 3 and an immersion roller 4 on both sides in the first case directly and in the other two cases with the interposition of the adjustability and deactivation the means enabling the rollers are mounted in a bearing plate 5 so that they can be adjusted together on the forme cylinder.
  • the bearing plate 5 is pivotally mounted in the frame 7 by means of a bolt 6 (FIG. 2).
  • the pivoting movement takes place by means of a pressure medium-operated working cylinder 8 articulated on the one hand on the frame 7 and on the other hand on the bearing plate 5 and is limited by an adjustable stop 9 which is fixed to the frame and serves to adjust the contact of the application roller 2 with respect to the forme cylinder 1.
  • the intermediate roller 3 is pivotably mounted on and off relative to the applicator roller 2 via a guide bushing 10 in a lever 12 mounted coaxially to the immersion roller 4 in the bearing plate 5 via a bearing bushing 11 (FIGS. 1 and 2).
  • the pivoting movement of the lever 12 is carried out by a pressure medium-operated working cylinder 13 articulated on this and the bearing plate 5 and is limited in the direction of the application roller 2 by an adjustable stop 14 which is attached to the bearing plate 5 and serves to adjust the contact of the intermediate roller 3 with respect to the application roller 2 .
  • the dip roller 4 wetted in a dampening solution tank 15 attached to the frame 7 is mounted in a further lever 17 via an eccentric bushing 16.
  • the eccentric bushing 16 is designed as a worm wheel 18, into which an adjusting screw 20 mounted on the lever 17 and equipped with an adjusting spindle 19 engages.
  • the lever 17 lies in a recess 21 via parallel guide surfaces 22; 23 displaceable in the direction of the intermediate roller 3 on the guide bush 10 of the lever 17 which projects in the region of the recess 21.
  • the recess 21 in the area of the center running through the dip roller 4 and intermediate roller 3 has a support surface 24 equipped with a curvature coaxial with the intermediate roller 3 for a positioning eccentric 25 mounted in the lever 12 for the intermediate roller 3 and opposite for the parking of the dip roller 4 the intermediate roller 3 can be adjusted to effect a displacement of the lever 17 in the direction of the center by means of a pressure-medium-operated working cylinder 26 articulated on the lever 17.
  • the lever 17 Via an adjusting spindle 27 articulated below the dip roller 4 on the lever 17 and guided in a threaded bore fixed relative to the lever 12 for the intermediate roller 3, the lever 17 can be moved with the dip roller 4 via the guide surfaces 22; 23 and the support surface 24 can be pivoted relative to the intermediate roller 3. So that's about a different one The levers 17 can be pivoted on both sides of the plunger roller 4, which in the axial direction can produce a different dampening agent dosage than the intermediate roller 3. This enables the plunger roller 4 to be supported axially via a self-aligning bearing 28 in the eccentric bushing 16 (FIG. 2).
  • the end shield 5 and the lever 12; 17 for the intermediate roller 3 and the plunger roller 4 are plate-shaped for reasons of cost and to realize their displaceability and are left with the claws 29; 30; 31 slidably held laterally (Fig. 4).
  • All rollers of the dampening unit are positively driven, the applicator roller 2 with the same peripheral speed from the forme cylinder 1 via two spur gears 32; 33 and an articulated shaft 34 (FIG. 3), which enables the pivoting movement of the application roller 2 relative to its spur gear 33 mounted in the frame 7, and the intermediate roller 3 and the dip roller 4 from a speed-adjustable motor 35 arranged on the outside of the frame 7 via a frame 7 in a bore penetrating, on the inside of the frame 7 in a recess 36 equipped with a spur gear 37 and a shaft 38 on the shafts 39; 40 of these spur gear 41; 42 are driven (Fig. 2).
  • the spur gears 41; 42 for the intermediate roller 3 and the submersible roller 4 via a corresponding tooth play and the spur gear 42 of the submersible roller 4 is additionally equipped with a curved toothing which enables it to be set.
  • distribution rollers 44 In order to equalize the impurities picked up by the forme cylinder in the dampening solution return and for an additional smoothing of the dampening solution film in the dampening solution supply, distribution rollers 44; shown in broken lines in FIG. 45 are provided, the traversing drive of which, in each case with the interposition of a cardan shaft to compensate for the pivoting movement of the bearing plate 5, is carried out by the forme cylinder 1 in a manner not shown.
  • the distribution rollers 44; 45 are each adjustable in the bearing plate 5 via an eccentric bushing relative to the applicator roller 2.
  • roller locks 46; 47; 48 are on both sides in roller locks 46; 47; 48 stored (Fig. 2; 3).
  • the application roller 2 and the dipping roller 4 are coated with hydrophilic rubber, the intermediate roller 3 and the distribution roller 45 in the dampening solution supply with chrome and the distribution roller 44 in the dampening solution return with copper or Rilsan.
