Definitions

  • the invention relates to a bearing for an ink fountain of a rotary printing press according to the preamble of claim 1.
  • Ink boxes are well known, e.g. by US-PS 4 058 058, in which both the ink fountain roller and the ink fountain are mounted in side frames of the rotary printing press.
  • Ink control elements attached to the ink fountain interact with the ink fountain roller, the ink fountain being arranged to pivot about means fixed on the side frame.
  • Swiveling ink boxes for rotary printing presses are e.g. B. become known from DE-B-12 90 154.
  • a paint box with a plurality of paint metering elements is shown, which can be pivoted about holding pins fixed on the side frame.
  • the holding pins engage in recesses in the side walls of the ink fountain.
  • the ink metering elements interact with the ink fountain roller.
  • Ink tanks mounted in this way have the disadvantage that they promote an annoying deflection of the ink fountain roller.
  • the deflection occurs because the ink control elements press against the ink fountain roller over the ink film.
  • an ink pan can be found which is mounted on the two pins of an ink roller.
  • the ink pan can be swiveled, but cannot be swiveled away, and has no ink metering elements which stress the ink roller against bending.
  • the invention is based on the object of designing a bearing for an ink fountain of a rotary printing press in such a way that a reduction in the bending length of the ink fountain roller is achieved, a plurality of ink metering elements interacting with the ink fountain roller.
  • the advantages which can be achieved with the invention consist in particular in that the shortening of the support distance of the ink fountain roller in the ink fountain reduces the deflection of the ink fountain roller caused by the ink control elements.
  • the ink fountain being mounted on the shaft ends of the ink fountain roller, the ink fountain can be pivoted away from the ink fountain roller.
  • An ink fountain roller 6 is arranged in a known manner between two side frames 1, a rotary printing press. Your two roller journals 7, 8 are supported by bearings 3, 4 in the side frames 1, 2.
  • the ink fountain roller 6 can be driven in a known manner from the main drive of the printing press or by a separate drive.
  • an ink fountain 9 is not attached to the inside of the side frames 1 and 2, as was previously the case, but to the roller journals 7 and 8. For this reason, it is as close as possible (4-6 mm) on both end faces 11, 12 of the ink fountain roller 6 on the roll neck 7, 8 z.
  • a supporting ring 16, 17 is fastened to an outer ring of the ball bearings 13.
  • Each supporting ring 16, 17 is provided with a semicircular groove 21, 22 in the middle on its outer surface 18, 19.
  • a stepped holding pin 26, 27 is screwed on each inner side 23, 24 of the side frames 1, 2, a stepped holding pin 26, 27 is screwed.
  • the holding pins 26, 27 engage in a bore 28, 29 in a side wall 31, 32 of the ink fountain 9.
  • the holding pins 26, 27 are resiliently suspended in the bores 28, 29.
  • the bores 28, 29 are approximately 8 mm larger than the diameter of the associated holding pin 26, 27.
  • a plastic bushing 30, 33 which receives the holding pins 26, 27, is pressed into the bores 28, 29.
  • a compression spring 36 can also be arranged in a recess 35 in the side walls 31, 32 of the ink fountain 9, the abutment of the compression spring 36 in the side wall 31, 32 and the force applied to the holding pin 26, 27.
  • a base plate 34 is fitted between the side walls 31, 32 of the ink fountain 9 and screwed to them.
  • a traction device 41 for example a wire rope
  • the traction means 41 wraps around the support ring 16 in the groove 21 by approximately 180 °, and its second end 42, designed as a rope thimble 43, is attached to a pin 44 which is positively connected to a one-armed pivot lever 46.
  • the pivot lever 46 is arranged in a laterally open recess 47 on the upper part 48 of the ink fountain 9 so as to be pivotable about a pivot 49 fixed to the ink fountain side wall.
  • the pivot lever 46 can be pivoted in such a way that the center lines of the first and second ends 39, 42 of the traction means 41 do not run parallel to one another, but at an acute angle a to one another. I.e. in this position, the pivot lever 46 has been pressed down beyond its dead center, and thus the ink fountain 9 is attached to the roll neck 7 or 8. Should the Connection ink fountain 9 - roller pin 7 are loosened, the pivot lever 46 must be moved clockwise.
  • the traction means 41 lifts out of the groove 21 and the cable thimble 43 can be removed from the pin 44. It goes without saying that this must be done for both roller journals 7, 8 in order to release the ink fountain 9-roller journal 7 and 8 connection.
  • the ink fountain 9 can then be pivoted about the holding pins 26 and 27.
