Definitions

  • the invention relates to a roller block adjustable to a plate cylinder of an offset or high-pressure machine, in particular for an inking unit, consisting of a plurality of transfer or application rollers with inner rollers hidden by outer rollers, with at least one transfer or application roller which can be pivoted about an outer transfer roller is, further consisting of arranged on the end faces of the fixedly mounted outer roller, respectively, about its roller bearing pivotable first bearing plates, in which at least one roller is mounted, which is in contact with the outer roller, with each first bearing plate rotatable relative to this second bearing plate for storing a roller is arranged, associated with the mounting and stopping means fastened on the first bearing plate, and wherein the first bearing plates together with the second bearing plates arranged thereon can be pivoted in such a way about the outer roller by means of a pivoting device nd that an inner roller is accessible in the pivoted position.
  • roller mill has become known through the obvious prior use of a machine from WIFAG, Bern.
  • an inking unit in which a plate cylinder can be inked over a number of inking rollers.
  • ink is fed to the inking rollers via two roller trains, so-called ink strands.
  • it is also known to pivot a further roll that can be adjusted to a stationary roll in order to switch it on and off or for changeover processes.
  • the disadvantage of this known roller block is that certain rollers cannot be replaced without the rollers hiding them being removed beforehand. The replacement of inner rollers covered by outer rollers thus requires a considerable amount of time.
  • the object of the invention is to further develop a roller mill of the type defined at the outset in such a way that an expansion and adjustment of rollers which are covered by other rollers is possible in a very short time without the expansion of the rollers covering them.
  • the advantageous design of the roller bearing means that the rollers, which are not freely accessible in normal operation, can be swiveled out in a simple and simple manner, so that they can be replaced without prior removal of further pressure rollers, for example after wear. Furthermore, service-friendly adjustment is possible without removing the outer rollers.
  • the invention can preferably be used in so-called two-strand or multi-strand inking units for offset or high-pressure machines. Another possible application is especially in the case of more complex dampening systems of offset printing machines or in so-called combined inking or dampening systems.
  • a not inconsiderable further advantage of an embodiment of the roller bearing according to the invention is that by using a stop in the pivoting device according to the invention after the necessary work has been carried out on the inner rollers, they only have to be pivoted back without a new adjustment of the pivoted rollers relative to the fixed rollers is required.
  • the inking unit 2 shown in FIGS. 1 and 2 which can be used for inking a plate cylinder 1, receives the ink required for inking the plate cylinder 1 in a conventional manner from an ink fountain with the interposition of possibly further inking unit rollers and an ink fountain roller operating as a lifting or film roller. Since this upper part of the inking unit is generally known, it has not been shown in FIGS. 1 and 2.
  • This single drum roller is referred to as ink strand A.
  • An ink ribbon B runs from the aforementioned inking unit roller 3, in its place a inking device can also be used, via inking unit rollers 7 and 8 to an inking unit 9.
  • Two inking rollers 10 and 11 are attached to the inking unit 9, which together with the inking roller 6 for one ensure even coloring of the plate cylinder 1.
  • the inking roller 11 is a so-called inner roller and is covered by the rollers 7, 8, 10 and the ink grinder 9, so that it is no longer freely accessible from the outside and above all without the removal of at least some the outer rollers cannot be replaced or adjusted.
  • a bearing plate 13 is rotatably arranged around the bearing bush of the color grater 9 on the two end faces of the color grater 9. These bearing plates 13 serve to accommodate the mounting of the inking rollers 7 and 8. On the plate 13, but rotatable relative to this, a further bearing plate 14 is also pivotable about the bearing pin of the ink grater 9. These arranged on the end faces of the ink grater 9 bearing plates 14 serve to accommodate the bearings of the inking roller 11. In order to be able to position the inking roller 11 on the plate cylinder 1 in the desired manner, an on and off device 15, z. B. in the form of pneumatic actuating means, with the help of which the bearing plate 14 and thus the applicator roller 11 can be pivoted independently of the bearing plate 13 and is thus adjustable.
  • the bearing plate 13 can be pivoted together with the bearing plate 14 by a pivoting device 16, 17, 18 and 19 so far clockwise around the ink fountain 9 that the inking roller 11 is freely accessible in the right end position and can be removed without changing an outer ink roller.
  • the mentioned pivoting device comprises a guide rod 16 which is pivotally articulated on one side on the bearing plate 13.
  • the other side of the guide rod 16, which is provided with a thread, is guided in a fixed but rotatable holder 17.
  • Adjustment nuts 18 and 19 are screwed onto the guide rod 16 on both sides of the holder 17, with the aid of which the position of the guide rod 16 in the holder 17 can be fixed.
  • an adjustment button 20 is provided on the setting and stopping device 15.
  • the position of the inking roller 11 relative to the plate cylinder 1, once set by means of the adjustment button 20, is not changed by the described pivoting about the roller bearing 21 of the inking device 9.
  • the color strand A can also be designed like the color strand B (mirror image).
