Definitions

  • Ink metering device for book and offset printing machines consisting of an ink fountain, an ink fountain roller, a squeegee and an ink fountain pen, the ink fountain consists of juxtaposed disks that oscillate individually and independently of each other between the ink fountain roller and an upper support roller and the width of which corresponds to a specific ink zone.
  • the CH-PS 169 362 shows an inking unit for rotary - printing machines arranged side by side with a plurality on a common shaft, individually switched on and stoppable vibrating rollers whose lengths each corresponding to the width of a printing plate.
  • a control disk with several cams of different sizes lying next to one another is arranged on a common shaft so as to be longitudinally displaceable and adjustable.
  • the object is to be able to program predetermined and / or calculated dosed amounts of ink in a programmed manner, as well as malfunctions in the course of printing with control technology with ma to be able to eliminate technical requirements.
  • the object is to be achieved with a color metering device in book and offset printing presses, which is said to be less susceptible to interference from paper components and fountain solution and is to enable a color requirement of the printing form that corresponds precisely to the ink supply.
  • an ink metering device which consists of an ink fountain with ink knife and an ink fountain roller with ink lifter for electronic ink zone remote controls for book and offset printing presses and in which several ink lifter wheels are provided which oscillate individually and independently of one another and whose width corresponds to a specific ink zone .
  • the object of the invention is to achieve ink transfer without gaps between the individual zones, the mounting of the ink-lifting discs being designed to be stable.
  • the holders of the paint lifter discs can be swiveled with springs and magnets.
  • the spring acts on the holder in such a way that the ink lifter disc rests on the upper support roller when the magnet is switched off.
  • the suspension of the brackets is chosen so that there is a mass balance, which leads to small control forces.
  • the design of the magnetic control mechanism is provided with end position damping.
  • the ink fountain roller is driven by the machine through gears so that the ink fountain roller adapts in proportion to the change in machine speed.
  • FIG. 1 an ink fountain 1 with a doctor blade 2 is shown.
  • An ink fountain roller 3 transports the ink through its direction of rotation to the squeegee 2.
  • the ink is reduced to a predetermined layer thickness on the ink fountain roller 3, the rest of the ink drips from the squeegee 2 back into the ink fountain 1.
  • the ink fountain 1 has a raised edge in the area of the squeegee 2.
  • a metering roller can also be used.
  • a row of ink lift disks 5 and a row of ink lift disks 6 are arranged below for the ink transport.
  • the ink lift discs 5, 6 are very stably supported on brackets 7, 8, so that the upper support roller 4 can carry out the back and forth movement of a friction roller without the brackets 7, 8 being bent laterally.
  • the brackets 7, 8 each pivot about pivots 9.
  • the suspension of the color control discs 5, 6 is designed on the supports 7, 8 so that a mass balance is made so that the control forces for controlling the color control discs 5, 6 are minimal.
  • Springs 10 and magnets 11 act on the brackets 7, 8 in the ratio 1/5.
  • the direction of action of the magnets 11 on the brackets 7, 8 is designed so that the ink lifting discs 5, 6 rest against the ink fountain roller 3 when the magnet 11 is switched on. When the magnet 11 is switched off, the springs 10 pull the ink regulator discs 5, 6 in rich tion of the top roller 4 down.
  • the drives can also be hydraulic or pneumatic instead of magnetic.
  • Fig. 2 shows an overall view of the ink lift discs 5, 6 distributed over the entire width of the ink fountain roller 3, in which the ink lift discs 5, 6 are clearly held on both sides by brackets 7, 8.
  • the inking discs 5, 6 are arranged opposite each other so that no empty gaps between the inking discs 5, 6 arise when transferring the ink from the ink fountain roller 3 to the transfer roller 4.
  • the ink lifter disks 5, 6 can be controlled in such a way that, viewed circumferentially, different ink stripe lengths can be transmitted at different stroke frequencies from zone to zone. Zero quantity regulations and a particularly high sensitivity as well as optimal reproducibility of the orders can be carried out.
