Definitions

  • the invention relates to an anilox roller for short inking units It is known that in short inking units with anilox rollers, as are known, for example, from DE-OS 37 04 433, the anilox rollers have to be changed frequently, according to the particular printing task to be performed.
  • the variety of printing tasks requires a wide range of variations for the amount of color, i.e. a variety of engravings of different capacities, which are realized by the shape, size and number of grid cups per unit area.
  • the provision of a large number of anilox rollers of different raster engravings causes considerable costs and the exchange of the anilox rollers is often not easy, for example due to lack of space or unfavorable roller or cylinder arrangements.
  • EP-A-0279394 discloses a holding device for applying a sleeve to a cylinder carrying a printing form. This and the document mentioned at the outset, however, do not provide any obvious information on the transferability to anilox rollers in short inking units, since the needs and special features prevailing there have not been addressed.
  • the object of the present invention is therefore to provide a novel device for a cylinder-sized anilox roller with which different amounts of ink are made available for inking the forme cylinder without removing the roller from the printing press or from the inking unit.
  • An inking unit with the inking unit roller according to the invention is suitable for the printing press shown in FIG. 1, which has printing units 1, 2, 3.
  • Each printing unit comprises a blanket cylinder 4, a plate cylinder 5, an inking roller 6 and an anilox roller 7.
  • Each of the plate cylinders 5 is assigned a dampening unit 8 and each anilox roller 7 a doctor blade inking unit 9.
  • the doctor blade inking units 9 each have a chambered doctor blade 10, which is from the anilox roller 7 can be turned off.
  • the anilox roller 7 can also be stopped by the inking roller 6.
  • the inking roller 6 in FIG. 1 has the same diameter as the plate cylinder 5, but it can also have the same diameter as the anilox roller 7 or the anilox roller 7 can have the diameter of the inking roller 6 or the cylinder 5.
  • the invention is described with reference to the anilox roller 7. However, within the scope of the invention it is also possible to use the invention on the inking roller 6 or cylinder 6 or on other inking rollers.
  • Fig. 1 shows further details of the doctor blade inking units, namely an ink supply 13, an ink pump 17 over a holder 27 for the unspecified ink tray and a holder 19 for the chambered doctor blade 10 as well as a support plate 28 and a traverse 29.
  • these parts play in context with the present invention with the exception of the doctor blade 10 no significant role.
  • the anilox roller 7, which, as mentioned, can also have the same diameter as the inking roller 6, is equipped on both sides with pins 32, 33, via which the anilox roller 7 can be stored in the side walls 1, 1 '.
  • a side wall here the side wall 1 referred to as “side I”
  • the openings 30, 31 must each have a diameter which is dimensioned such that the sleeves 34 which can be pushed onto the inking unit rollers, here onto the anilox roller 7, can be pushed through the openings 30 and 31, respectively.
  • the sleeve 34 has a raster with a certain raster engraving.
  • the anilox roller 7 can be provided through the associated opening 31 with a sleeve 34 which has the desired raster engraving in order to supply the inking unit or the forme cylinder 5 with a corresponding amount of ink.
  • the anilox roller 7 can also be conical in order to facilitate the application of the sleeve 34.
  • the auxiliary holding device 35 to 43 essentially consists of an auxiliary shaft 36 which is arranged on the gear box 35 approximately transversely to the axle journal 32 and is mounted on both sides in vertical walls of the gear box 35.
  • the auxiliary shaft 36 preferably has recesses 38 in the middle. With these, it is placed on the journal 32 before the bearing of the journal 33 on the other side of the anilox roller 7 is removed so that the sleeve 34 can be pushed on.
  • eccentric mounting of the auxiliary shaft 36 as indicated at 42, can be rotated by means of a square 43 on an axle journal of the auxiliary shaft 36, so that the eccentric mounting initially places it on the axle journal 32 and adjusts it vertically so that the desired position the anilox roller 7 is reached.
  • the employment can be predetermined by an adjustable stop 41.
  • the auxiliary shaft 36 On the other side of the gearbox 35, the auxiliary shaft 36 has a thread on which on both sides of the side wall of the gearbox 35 for the horizontal adjustment of the auxiliary shaft 36 adjusting nuts 39, 40 are arranged, which enable a corresponding left / right shift, whereby the anilox roller 7 adjust or adjust in this direction. is fixable.
  • the anilox roller 7 between the side walls 1, 1 ' can be brought into a defined position or held there, so that the sleeve 34 can be easily applied through the associated opening 31 can be.
  • a corresponding bearing (not shown here) is again placed on the journal 33 of the anilox roller 7 in the printing unit side wall 1, after which the auxiliary shaft 36 can be slightly lifted from the journal 32 by rotating the square 43, so that the anilox roller 7 or the journal 32 is freely rotatable again.
  • the detent roller 7 can be forcibly driven via a drive 37.
  • auxiliary holding device serves only as a preferred exemplary embodiment, but does not limit the field of application of the invention, since the inking roller cleared on one side, here the anilox roller 7, can be held in the cleared position in order to apply a sleeve, here the sleeve 34.
  • inking rollers are equipped with exchangeable sleeves, corresponding to the sleeve 34 shown in FIG. 2, the possibility arises, e.g. after the corresponding coatings (plastic or rubber) have worn out or if other roller coatings are advantageous for certain jobs, the change can be carried out in a simple manner without changing or removing inking rollers in the area of the inking units which is difficult to access anyway.
