Definitions
- the invention relates to an inking unit for a printing press, in particular offset printing machine, according to the preamble of Claim 1.
- the color to be printed is from an ink fountain and an ink fountain roller interacting with it, a lifter roller and other inking rollers the inking rollers interacting with a forme cylinder fed.
- One or more of the ink rollers are included formed as a friction roller, which during the rotation also perform axial traverse movements. These traversing movements can also be adjusted in phase and / or stroke be so that the print length becomes noticeable counteracting differences in color density can.
- DE 34 24 721 C2 describes an inking unit of a printing press of the kind briefly outlined above further shown a friction drive, in which a Rotary movement of a disc the axial reciprocation a friction roller is generated.
- the friction rollers of modern offset inking units are not only used for Generation of the axial traversing movement is driven instead also set in rotation. This is necessary to avoid one only by viscosity the paint-driven roller is not strong enough from the surrounding ink rollers, i.e. in certain circumstances unwanted slip occurs.
- the object of the present invention is therefore an inking unit to further develop in accordance with the preamble of claim 1, so that a simple and space-saving drive of a friction roller is possible.
- the drive for the Rotation movement at one end of the friction roller and the drive for the rubbing movement on the opposite one End of the friction roller is arranged.
- both on the A and on the B-side the respective drives for the Rotational movement of the grater or the rubbing movements the grater, each with a traction device in the form of a wedge or other belt drive coupled together and by each driven by a separate drive motor.
- FIG. 1 and 2 show an inking unit, in which with a Form cylinder 1 inking rollers 2 interact.
- the inking rollers 2 stand over friction 3 and further inking rollers 4 with a friction roller 3 in connection, which with a Lifter roller 5 cooperates, which corresponds to the lifter cycle
- Ink is removed from an ink fountain roller 6 and sent to the single drum roller passes.
- the Ends of the grater 3 pulleys 7 on which one Traction means 10 in the form of a toothed belt or multi-groove belt are entwined. So that the pulleys 7 in the intended Ways can be wrapped around by the traction device additionally deflection disks 8 which are fixed to the frame are stored.
- the traction means 10 is also a drive pulley a drive motor 9 looped so that the individual friction rollers 3 together by this motor 9 in Rotation can be driven.
- Figure 2 shows the formation of the inking unit from the opposite Side according to Figure 1.
- individual friction gear 11 At the ends of the friction rollers are arranged individual friction gear 11, in this way are such that a rotating movement of a pulley 12 inside this friction gear 11 in an axial oscillating movement be transmitted.
- the individual friction gear 11 assigned to the rubbers 3 preferably are designed as individual gear blocks - Each have a pulley 12, which of a common traction means 13 are wrapped. For generation the necessary wrap angles are additional pulleys 15 provided fixed to the frame. Furthermore, that is common traction means 13 around a drive pulley of a drive motor 14 out. The drive of the individual friction gears 11 thus takes place from this motor 14.
- Figure 3 shows a grater 3, which at its two ends each a pin 16, 17 in frame walls, not shown a printing press is stored. At one end is the grater 3 rotatably but axially displaceable via a pin 16 connected to a pulley 7, around which the Traction means 10 is looped. On the opposite On the side, the grater 3 has a pin 17, which in the Immersed housing of the friction drive 11. Through this friction gear 11 is the axial traversing movement of the grater 3 embossed - as shown by the double arrows in Figure 3.
- the connection of the friction gear 11 with the pin 17 of the grater 3 is such that only one axial, but not a rotary coupling.
- the friction gear 11 are preferably such that the Stroke and / or the phase of the axial traversing movements independently can be adjusted from each other. So it is possible, each in the inking unit shown in Figures 1 and 2 single friction roller 3 in any way with respect to adjust other graters and make appropriate movements produce. This is a very differentiated response to the different color flow distributions accordingly the subject possible.
