Definitions

  • the invention relates to a device in offset printing machines for driving a dampening unit according to the preamble of the claim.
  • a device of the type mentioned is known from DE-PS 3 623 590, Fig. 3.
  • a water box roller and a metering roller are driven independently of the machine with a separate, speed-controllable gear motor via a clutch, a first gear and a second gear, which is firmly seated on the pin of the water box roller.
  • Another gearwheel drives the metering roller either synchronously, i.e. without circumferential slip or asynchronous when the translation is changed, i.e. with slip to the water tank roller inevitably.
  • the latter is disadvantageous when washing dampening and inking units together, e.g.
  • the object of the invention is to drive the metering roller solely by friction from the water tank roller when washing the dampening and inking units together.
  • the advantage of the invention is that washing the water tank roller, the metering roller and the applicator roller together of the dampening unit and the rollers of the inking unit coupled via the bridge roller is possible without slippage by friction of the roller surfaces, while the positive gear drive of the dampening unit is disengaged.
  • This position is also suitable as a painting position, that is, with the intermediate gear between the metering roller and water tank roller pre-dosed lacquer between the water tank roller and application roller can be applied continuously in a metered manner, the intermediate roller 5 being switched off from the application roller 2, and if necessary the metering roller can also be turned off be so that a two-roller dampening or coating unit is created.
  • the plate cylinder 1 and 2 leads dampening fluid from a dampening solution tank through a water tank roller 3 via an applicator roller 2 directly onto the printing plate of a plate cylinder 1.
  • the plate cylinder 1 is supported by pins at both ends in side walls 16 in the printing press.
  • the cones are driven in a conventional manner, not shown, by gears arranged outside the one side wall from the main drive of the machine.
  • the strength of the dampening liquid is adjusted by means of a metering roller 4.
  • the dampening unit 2, 3, 4 thus guides the dampening liquid in a very short way to the pressure plate of the plate cylinder 1, so that the dampening solution evaporation is low.
  • the application roller 2 is connected via two oleophilic intermediate rollers 5, 6 to the first inking cylinder 8 of an inking unit, at least one of the intermediate rollers 5, 6 being able to be switched on and off by the ink supply and / or the fountain solution supply by known means not shown in the drawing. With 7 an inking roller is designated.
  • the dampening unit can be connected to the inking unit in a known manner by only one oleophilic intermediate roller, then to the first inking roller.
  • the metering roller 4 is mounted on both sides in levers 17, 20 which can be pivoted about the axis of the water tank roller 3 and can be adjusted in a known manner in terms of their center distance with respect to the water tank roller by rotating eccentric bushes, not shown in the drawing, wherein double-eccentric mounting is also possible is so that the metering roller can be adjusted by means of a hand lever or the like.
  • the metering roller 4 could also be brought into an inclined position with respect to the water tank roller axis and the means for this are not shown in the drawing, since they are also known.
  • an intermediate gear 11 is rotatably mounted in the lever pivotable about the pin 18 of the water tank roller 3 by means of a bearing pin 22, which is in meshing engagement with a gear 12 seated on the pin 19 of the metering roller 4 and is in meshing engagement with an intermediate gear 9.
  • the intermediate gear 9 is in meshing engagement with the gear 10 seated on the water tank roller 3 and the drive is connected to a speed-adjustable gear motor 15 via a belt drive 13 and a clutch 14.
  • the inevitable drive of the water tank roller 3 and the metering roller 4 by means of gear wheels 9 to 12 can be disengaged and engaged by separating and restoring the tooth engagement of the two intermediate gear wheels 9, 11 by pivoting the lever 17 about the pin 18 of the water tank roller 3 with gap "S" ( see Fig. 2).
  • the pivoting of the lever 17 about the pin 18 of the water tank roller 3 takes place by means of a working cylinder 24 which is articulated on the side walls 16 with a pivot point 26.
  • the piston of the working cylinder 24 is received by means of a pin 23 on the fork-shaped end of the lever 17 (see FIGS. 1 to 3).
  • the bearings are indicated, in which the pins 18 and 19 of the water tank roller 3 and the metering roller 4 are rotatably received in the pivot levers 17 and 20, respectively.
  • the eccentric bush 25 is used to adjust the center distance of the rollers 3, 4 and is provided on one of the two roller axes.
  • the drive works as follows:
