Definitions

  • the invention relates to a drive device for a roller, preferably in offset printing machines according to the preamble of the main claim.
  • a dampening unit is known in which the dampening solution is conveyed from a dampening solution container (water tank) by means of an immersion roller (dampening roller) to a metering roller and is further transferred to a downstream inking roller.
  • the dip roller is set in rotation by a separate drive via a traction mechanism.
  • the speed of the immersion roller can be regulated.
  • the solution shows no axial rubbing of the roller.
  • US Pat. No. 3,635,167 is an offset printing machine with a drive for the plate cylinder known as well as rollers.
  • a pinion output unit is in shape in a chain drive a sprocket with stub shaft arranged, on the one hand from the stub shaft a cam roller engaging in it and a cam roller (groove curve)
  • the friction drive for two rollers takes place and on the other hand the stub shaft a gear that carries for the rotation drive with gears of the two neighboring Rollers is coupled.
  • DE 41 40 048 A1 describes an inking unit for a printing press with at least one known a friction roller.
  • the friction drive of the friction roller is through a actuatable clutch can be stopped or switched on while the printing unit continues to rotate.
  • the friction drive of the friction roller takes place by means of a gear transmission Plate cylinder.
  • a disadvantage of the last two versions is that both documents are not individual drives have for the respective roller. Both rollers are each in the Printing unit drive integrated.
  • the object of the invention is therefore to develop a separate roller drive, the Axial drive (friction of the roller) independent of the radial drive (rotary movement) of the Roller is.
  • the device of a roller drive according to the invention is suitable for rollers in Painting equipment, folding units and especially in dampening systems. Independent of The machine speed of the printing press becomes constant via the separate drive Guidance of the medium to be conveyed, such as paint, ink or dampening solution, guaranteed.
  • the axial drive of the roller is preferably kept constant, the radial drive in the coupled state, the roller is synchronized with the axial drive. Im decoupled The radial drive is stopped.
  • the axial drive of the roller is also retained for the "washing rollers" operating mode, the radial drive, however, is decoupled and thus stopped.
  • the axial drive causes that the washing time is shortened by the trituration and the roller edges are also washed will. This improves the washing result in the "washing rollers" mode and the duration of the washing time is noticeably reduced.
  • An offset printing unit consists of a plate cylinder 1, an adjacent blanket cylinder 2 and an inking unit 8 and a dampening unit.
  • the dampening system is formed from a dampening solution tank (water tank) 3, one as a dampening roller (immersion roller) acting roller 4, which is in contact with a dampening roller 6 and a metering roller 5, which is assigned to the roller 4.
  • a bridge roller 7 is arranged, via which the dampening unit can be selected 3 to 6 can be coupled to the inking unit 8.
  • the roller 4 should have a roller drive.
  • a drive unit 9 e.g. an electric motor attached.
  • the drive unit 9 acts on a drive member 11 designed as a gear, which preferably has a traction means 10 a toothed belt rotated.
  • the traction means 10 is with a first Output unit for the axial drive and with a second output unit for the radial drive of the roller 4 in engagement.
  • An output member 12 is on one on the machine frame 14 fixed storage 15 attached.
  • the storage 15 consists inter alia. from a wave, which has an eccentric bolt on one side.
  • the eccentric bearing 15 is with a coupling 16 rotatably connected, which on two swivel joints on one Machine frame 14 fixed angle lever 17 acts.
  • the angle lever 17 is gear technology a ternary link and has a cam roller at one end, which is used in a cam controller 19 rotates.
  • the cam controller 19 is axially and radially movable Fixed rod 18 which is coupled to the roller 4.
  • the shaft 20 is mounted in the machine frame 14 parallel to the roller 4 and has a pneumatically acting coupling 21, which between the shaft parts is arranged.
  • a gear 22 is fixed on the shaft 20 at the free end.
  • the gear 22 is in engagement with an externally toothed bearing bush 23 arranged on the roller 4.
  • the bearing bush 23 is mounted in the machine frame 14 and at the same time forms one Slide bearing 24 for the pin of the rollers 4.
  • the bearing bush 23 is with a pin 25 connected to the pin of the roller 4 or optionally to the rod 18.
  • the pin 25 is movable in the radial direction for the rubbing in a longitudinal guide 26.
  • the exemplary embodiment represents a preferred roller drive.
  • the output unit can likewise have a clutch for the axial drive, which preferably in the area of the bearing 15 is arranged.
  • the roller drive can also via two couplings for the output unit of the axial drive in the area the bearing 15 and for the output unit for the radial drive in the region of the shaft 20th
  • the mode of action is as follows:
  • the drive unit 9 is actuated and sets the drive member 11 in rotary motion.
  • the traction means 10 rotates and sets the first output unit 27 for the axial drive of the roller 4 in motion and at the same time the second output unit 28 for the radial drive of the roller 4 is set in motion by the traction means 10.
  • the output member 12 rotates on the bearing 15 and the eccentric sets the coupling 16 in motion.
  • the swinging movement of the coupling in an axial drive movement (rubbing) of the rod 18 is deflected.
  • the rod 18 actuates the roller 4.
  • the output member 13 rotates on the shaft 20. In the coupled state, this is Transfer torque from the shaft 20 to the gear 22.
  • the gear 22 is offset the bearing bush 23, via its external toothing, in a rotational movement.
  • the rotary motion is from the bearing bush 23 via the pin 25 to the roller 4 through the rod 18 transferred. If the rotary movement of the roller 4 is to be stopped, the Coupling 21 pneumatically activated, such that a technical decoupling from the output member 13 and gear 22.
  • the part of FIG Shaft 20 is brought to a standstill while the part of shaft 20 carrying output member 13 is stopped continues to rotate by the drive of the traction means 10.
