Definitions

  • the invention relates to an inking unit of a rotary printing press, in particular offset printing press, consisting of transfer and application rollers accessible from the outside and inner transfer and / or application rollers accessible from the outside only after pivoting about a stationary roller and / or removal of rollers, at least of which two rollers are mounted in pivotable lifts and have devices for positioning and pivoting rollers, the pivotable levers of the applicator rollers being mounted on eccentric bushings which have adjusting means by which the pivotable levers can be adjusted to the adjacent stationary transfer roller.
  • Such inking units are known, e.g. from DE patent application F 6910 dated 06.08.51, CH-A 443 355 and DE-PS 3 112 745.
  • the devices described therein enable the swiveling of one or two rollers around a further stationary application or transfer roller and thus access to inner rollers, which are covered by outer rollers or otherwise covered, in order to enable their service-friendly adjustment or removal.
  • the invention has for its object to provide an inking unit, in which a service-friendly access from only one side is guaranteed with more than two application rollers and / or transfer rollers covered by external rollers or otherwise covered by pivoting by more than two stationary rollers, thereby achieving should be that such an inking unit can be rigidly connected to the printing unit.
  • the inking unit shown in FIG. 1 receives the dampening solution in a conventional manner via the dampening unit 3 and the rollers 4, 5, 6 the ink required for inking the plate cylinder 1.
  • the ink is transferred via transfer rollers 15, 17, 18 to a stationary transfer roller 11 and via a further stationary transfer roller 13 and a transfer roller 16 to a lower stationary transfer roller 12.
  • From the stationary transfer rollers 11, 12, the finely ground ink film is transferred from application rollers 7 to 10 connected in series to the plate cylinder 1, a further transfer roller 14 connecting the application rollers 8 and 9.
  • Fig. 1 it can be seen that the application rollers 8 to 10 and the transfer rollers 14 to 18 can be removed from below after several switching operations and no service-friendly access to the removal and / or adjustment of the application rollers 7 to 10 is available from another side, without decoupling the entire inking unit from the printing unit.
  • the transfer roller 14 resting on the inner applicator rollers 8, 9 and all other portable transfer rollers 15 to 18 are supported against stationary transfer rollers 6, 11, 12, 13 in a single bearing arm 21 via springs 22, 23, 32.
  • the transfer rollers 15 and 16 are removed from their spring-loaded bearing levers 19, 20, with the upper tra tion rollers 17 and 18 are relieved and can be removed.
  • the bearing arm 21 is then after loosening an index bolt 24 by adjusting an eccentric bush 25, which is arranged centrally to the transfer roller 13 on its fixed axis, by 180 °, as shown in FIG. 2, with the eccentric center and the transfer roller 14 from item I to item II movable, the spring 50 is first relaxed.
  • the bearing arm 21 with the entire bearing and the transfer roller 14 can be pivoted according to item III.
  • An index bolt engages in a bore 26 on the stand and secures this position of the bearing arm 21, in which all application rollers can be adjusted from below.
  • the transfer roller can be removed by folding down a notch lever, not shown.
  • All application rollers 7 to 10 are mounted in levers 28 to 31 which can be pivoted about the stationary transfer rollers 11, 12.
  • the swivel device for the application rollers 9, 10 around the Transfer roller 12 consists of pivoting levers 53, 54 rotatable on bolts 40 and a bush 43, on one side of which spring rods 34 and 39 are slidably arranged, which by rotating in opposite directions in bearing bolts 36, spiral spring pin 37 and intermediate pieces 33, 40 threaded rods 35 and 3 can be moved in such a way that the levers 30, 31 articulated on the other side of the pivot levers 53, 54 can be pivoted either with the applicator roller 9 via a connecting piece 42 or with the applicator roller 10 via a switching rod 55.
  • the pivoting device around the stationary transfer roller 11 is designed to pivot the applicator roller 8 and to position the applicator rollers 7, 8.
  • a spring rod 45, 49 is articulated on the lever 29 of the application roller 8 via a spring rod support 46.
  • the spring rod 45 slides in a spring tube 47 which can be screwed into a spring tube support 44 via a plug 48.
  • the spring tube support 44 is articulated on the lever 28 of the applicator roller 7, which is not pivoted away.
  • levers 28 to 31 are each mounted on eccentric bushings arranged one behind the other, which are connected by known adjusting means, e.g. Worm gearboxes are adjustable in order to be able to adjust the application rollers to the respective stationary transfer rollers by changing the center distances.
  • the entire bearing of the applicator rollers 7 to 10 receives a torque from the pivoting devices around the stationary transfer rollers 11, 12 by spring force, which causes both the adjustable adjustment of the applicator rollers 7 to 10 to the plate cylinder 1, as well as the parking lock for changing the applicator rollers 8 to 10.
