Definitions

  • the invention relates to an inking unit for printing presses, in particular offset printing machines, in which the ink is metered from an ink reservoir to the inking rollers of the inking unit, individual rollers of this inking unit being in contact with the plate cylinder as changing ink transfer rollers, which are preceded by changing inking rollers.
  • Inking units are generally based on the task of feeding the printing plate of an offset printing press a uniform, thin ink film. Depending on the type of printing form, however, these inking units can appear which have a negative impact on the print quality.
  • an inking unit in which at least two distribution rollers are provided. However, these are assigned to another area of the inking unit and are practically driven at the same stroke frequency, the stroke movement of the one friction roller being superimposed only by a small oscillating oscillating movement which, seen over several periods of the stroke frequency, practically does not change the same.
  • CH-A-603 359 also discloses a device for an oscillating friction roller, with which the stroke frequency can be changed with a constant stroke amplitude.
  • Ink rubbing rollers are known from various writings: From DE-OS 1 611 196 z. B. a color distribution roller is known in which a gear is provided in the interior of the roller through which a relatively long stroke period can be achieved.
  • the disadvantage of the device is, in particular, that due to the compact internal structure and the complex gear mechanism of the distribution roller, an inadmissibly high weight is created for easy and subsequent installation as an application roller. It should be noted that application rollers must be pivoted away.
  • An embodiment of the distributor roller according to DE-OS 2 045 717 cannot be used for a distributor roller, as is to be used in the invention, since the space inside the tube body is cramped. Furthermore, in this embodiment of the applicator roll there is a stroke frequency which does not meet the prerequisite for the invention.
  • the object of the invention is to improve a known inking unit by simple measures so that uniform inking of the printing cylinder is possible and faults z. B. are avoided by stenciling, the measures can also be applied to existing inking units if possible.
  • the advantage of this device consists primarily in the fact that such a uniform ink film can be applied to the printing plate due to the differing stroke frequency between the friction roller and the application roller, so that perfect printing quality can be achieved as the printing result.
  • Another advantage is that due to the special design of the inking rollers it is easy to retrofit existing inking units.
  • the simple drive of the inking roller shaft allows the stroke frequency of the inking roller to be dimensioned in a very inexpensive manner in such a way that optimal printing results can be achieved.
  • Another advantage with regard to the service life of the printing plate is that this is increased by the use of an application roller coating, as is customary in letterpress machines.
  • control gear enables light a continuous adjustment of the stroke frequency of the distribution to different print jobs.
  • the ink is metered from an ink reservoir 1 via an ink lifter 2 to a 1st friction roller 3.
  • This 1st rubbing roller 3 is assigned a plurality of transfer rollers 4, which take over the ink transport.
  • the ink passes through several transfer rollers 4 to further rubbing rollers 6 and 7.
  • These rubbing rollers 6 and 7 are assigned inking rollers 8-11, which feed the ink to the plate cylinder 12 in finely divided form.
  • the fourth inking roller 11 and at least one further inking roller 8-10 are designed as a rubbing roller.
  • the friction roller 11 shows in its sectional view a tubular body 13 which is provided with a coating 14.
  • the tubular body 13 is freely rotating on the shaft 15.
  • a drum curve 16 is fixedly connected to the shaft 15 at one end.
  • a cam roller 18 engages in the cam track 17 of the drum cam 16 and sits on a roller bolt 19 fastened to the tubular body 13.
  • the friction roller 11 is driven by the friction roller 7 by means of friction. With the shaft 15 at a standstill, the friction roller 11 would execute an oscillating movement in this case, in such a way that one stroke occurs per revolution of the friction roller 11.
  • a gearwheel 20 is attached to the shaft 15 and firmly connected to the latter.
  • This gear 20 meshes with a gear 21 attached to the grater 7 and sets the shaft 15 in rotation.
  • a relative speed occurs between the casing body 13 and the shaft 15, by means of which the drum curve 16 lags behind the tubular body 13.
  • the fact that tubular body 13 and drum curve 16 have the same direction of rotation reduces the relative speed between the tubular body 13 and shaft 15 and with the drum curve 16 so that, according to the translation of the gears 20 and 21, only a fraction of the stroke per friction roller revolution is present.
  • the gear 21 on the grater 7 is designed as a divided gear which must be screwed onto the grater pin of the grater 7.
  • the coating 14 of the tubular body 13 from a material which has the properties of the material commercially available under the name Febolith 01 33/30.
  • the friction function of the application roller is switched off, this can be done quite simply by removing the roller bolt 19 together with the cam roller 18.
  • the speed of the shaft can be increased so that the speed of the shaft 15 is equal to the speed of the tubular body 13 and thus synchronous movement of the cam roller 18 and drum cam 16 occurs, whereby the friction frequency becomes zero.
  • Another possibility of switching off the friction movement of the applicator roller is achieved by arranging a clutch 22 between the gear 20, 21 and the shaft 15.
  • the coupling 22 is to be designed in such a way that when the transmission 20, 21 is uncoupled, a relative rotation of the shaft 15 relative to the tubular body 13 and thus a traversing movement of the inking roller is not possible.
