Definitions

  • the invention relates to a roller block that can be adjusted to a plate cylinder of an offset or high-pressure machine, in particular for an inking unit, consisting of a plurality of transfer and application rollers accessible from the outside and inner transfer and / or application rollers covered by the outer rollers, with at least one transfer roller. or applicator roller, which is pivotable about a further transfer or applicator roller.
  • 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 for starting and stopping or. to swivel an additional roller that can be adjusted to a stationary roller.
  • the disadvantage of these known roll stands is that certain rolls cannot be replaced without the rolls covering 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 or 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 pivoted out without great expenditure of time and in a simple manner, so that they can be replaced without further removal of further pressure rollers, for example after wear. Furthermore, a 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 in the more complex dampening units of offset printing presses or in so-called combined inking and dampening units.
  • a not insignificant further advantage 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, these only have to be pivoted back again without the need to readjust the pivoted rollers with respect to the stationary ones Rolling 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 was not shown in FIGS. 1 and 2.
  • the ink coming from the ink fountain, not shown passes via an inking roller 3 and via inking rollers 4 and 5 to an inking roller 6, which inks the plate cylinder 1.
  • This single drum roller is referred to as ink strand A.
  • a color strand B extends from said F arbwerkwalze 3, in its place.
  • an ink fountain pen can also be used, via inking rollers 7 and 8 to form an ink fountain 9.
  • Two inking rollers 10 and 11 are placed on the ink fountain 9, which, together with the inking roller 6, ensure uniform inking 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 receive the bearings 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 and thus adjusted independently of the bearing plate 13.
  • 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 having to replace 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 on and off 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).
