Definitions

  • the invention relates to an ink fountain for printing machines, with adjustable metering elements, which is mounted such that it can be pivoted relative to a ink fountain roller on an axis, the latter being held on parts of the printing machine.
  • DE-AS 1 942732 shows an ink fountain for printing presses with ink knives and zone screws, which is pivotably supported by an axis relative to a ink fountain pen.
  • the focus of the ink fountain is chosen so that it rests against a stop on the machine frame.
  • the object is achieved to create a setting option for the color profile, color gap and angle of attack of a color box while maintaining the support line between color knives and color profile levers.
  • the object of the invention is to keep the ink layer thickness on the ink ductor constant even in the event of extreme changes in temperature of the printing press.
  • an ink fountain for printing presses of the type mentioned in that adjustably guided distance compensation elements are attached to the ink fountain, which have an expansion coefficient greater than steel, that the distance compensation elements are supported by spring-loaded tie rods, which are supported on the press side and held on the ink fountain are, can be pressed under constant force against a cylindrical surface in lateral end areas of the ink ductor, and that the tie rods can be locked in the area of disc springs by means of threaded bolts.
  • Adjustable distance compensation elements are attached to the ink fountain, which have a compensation coefficient greater than steel. Different designs are available as distance compensation elements, depending on which of the printing machines the distance compensation element is to be used for.
  • the distance compensation elements compensate for temperature differences of the printing press due to their expansion. Once the dosing elements have been set, they remain at a constant distance from the ink ductor over long periods of operation.
  • the expansion or contraction of the distance compensation elements depends on the temperature fluctuations.
  • the distance compensation elements can be pressed under constant force against a cylindrical surface in lateral end areas of the ink ductor by means of spring-loaded tie rods, which are supported on the printing machine side parts and are mounted on the ink fountain.
  • the plate springs are set to a specified value using a torque wrench and a star grip during assembly or repair. After the exact setting of the preload of the spring forces, the threaded bolt is adjusted as a mechanical stop.
  • the ink fountain side walls themselves are used as distance compensation elements.
  • an equally large plate with an expansion coefficient greater than steel can also be screwed onto the ink fountain side walls, to which stop rollers are attached.
  • Another version avoids frictional forces by supporting the distance compensation elements against the cylindrical bearing shells of the ink ductor.
  • the tie rods can be locked in the area of disc springs using threaded bolts.
  • the pretension set by means of the torque wrench with the distance compensation elements is thus maintained constant.
  • a sealing and temperature-compensating felt insert is attached to the distance compensation elements in the area covering the ink duct.
  • FIG. 1 shows a partial area of a printing press 1 with an ink fountain 2 and metering elements 3 located thereon in the area of an ink ductor 4 in a side view.
  • the ink fountain 2 is pivotally mounted on an axis 5.
  • a distance compensation element 9 which is designed in the form of a rod 17, is adjustably arranged in a guide 18.
  • the guide 18 is fastened to the ink fountain 2 by means of screws 9.2, 9.3 via a special holder 2.1.
  • the holder 2.1 is also arranged laterally on the ink fountain 2 so as to be rotatable about the axis 5.
  • the rod 17 is adjustable in the guide 18 by slight twisting by the smallest difference. During the adjustment process, the entire ink fountain 2 swivels about the axis 5 and thus changes the gap to the ink duct 4.
  • the rod 17 is fixed in the guide 18 with a screw 9.1.
  • a drawbar 10 engages the ink fountain 2 at a short distance from the axis 5.
  • the pull rod 10 is supported over a contact surface 10.1 on printing machine side parts 6, not shown, via plate springs 13.
  • the plate springs 13 are guided in spring holders 20.
  • a star grip 10.3 is arranged in the area of the plate springs 13, which has a threaded bolt 14. When set, the threaded bolt 14 acts as an end stop of the pull rod 10.
  • FIG. 2 shows a top view of the same section of the printing press 1 as FIG. 1.
  • the bearing shell 4.1 of the ink ductor 4 like the contact surface 10.1, is held on a printing machine side part 6.
  • the direction of action of the pull rod 10 is only slightly offset from the direction of action of the distance compensation element 9.
  • the plate springs 13 in the area of the contact surface 10.1 ensure the above-mentioned prestressing of the rod 17.
  • FIG. 1 shows a side view similar to FIG. 1 with a different embodiment of the distance compensation element 7.
  • the distance compensation element 7 is the ink fountain side wall 15 on the side of the ink fountain 2.
  • two stop rollers 16 are fastened to the ink fountain side walls 15 .
  • the pull rod 10 is particularly advantageously arranged centrally between the two stop rollers 16 in the pressure direction of the ink fountain side wall 15.
  • the contact surface 10.2 is screwed to the ink fountain 2.
  • the pretensioning via the pull rod 10 is kept constant, similar to the first version, by means of plate springs 13 in spring holders 20, just like the locking of the pull rod 10 by means of the threaded bolt 14.
  • a felt insert 19 is fastened for sealing.
  • FIG. 4 shows the top view of FIG. 3.
  • the ink fountain 2 is mounted on the axis 5 in the printing machine side part 6.
  • a third very simple embodiment consists in that the spacing elements 8 in the form of the ink fountain side walls 15 are made of a brass or aluminum material and are screwed onto the ink fountain side wall 15 parallel to the latter. In this case, the stop rollers 16 are attached to the distance compensation elements 8.
