Definitions

the invention relates to a control for a lifter inking unit of a printing press, in particular sheet-fed offset printing press according to the preamble of claim 1.
the ink to be printed is fed by an ink fountain roller fed to the rollers of an inking unit via a lifting roller and via inking rollers on the printing form mounted on a plate cylinder upset.
the lifter roller is in particular between an ink fountain roller and one trained as a friction roller ink roller back and forth. This movement is assigned to the bearing of the lifting roller Drive generated.
the frequency of the lifting movement (lifting stroke) and also the width of the lifting strip, i.e. the amount of through by the ink fountain roller the color to be removed from the siphon roller (length of the color strip) is adjustable.
DE 44 36 953 C1 describes such a method for producing a Ink layer thickness distribution on inking unit rollers of an inking unit of a printing press known.
this method during a first number of Machine revolutions through the ink metering elements on the ink fountain roller a quantity of color introduced into the inking unit, this quantity of color the so-called Corresponds to the basic color quantity of the next order. Then during a second number of machine revolutions for the coming one Print order determined metering profile set on the ink fountain roller, until then the actual printing with releasing the sheet travel and starting the Printing unit cylinder takes place.
the lift strip width set to a possible maximum value i.e. the lifter roller takes the largest possible amount of ink from the ink fountain roller and transfers this on the friction roller arranged after the lifting roller. It is also provided that that the printing machine is run up to the highest possible speed is (if possible the maximum speed of the machine), so that the corresponding Number of machine revolutions in the shortest possible time is going through.
ink usually runs into the inking unit at the beginning of the shift, i.e. with cold machine. Then the machine will run at maximum speed driven, this causes increased wear in the bearings of cylinders, rollers and other moving machine parts. To do that reducing the resulting increased risk of machine damage, Accordingly, the running-in process with a cold machine must always be reduced Machine speed.
the printing machine has a lifter inking unit with one that changes automatically depending on the machine speed Width of the squeegee strip, this in turn requires that the opposite accordingly the maximum speed reduced the running-in speed narrower lift strip width comes to adjustment, which is the running-in process additionally extended.
a lifter inking unit with depending on the machine speed tracking strip width is from DE 43 14th 426 C2 known.
the object of the present invention is therefore to provide a control for a lifter inking unit a printing press according to the preamble of claim 1 expand so that a while avoiding the disadvantages mentioned above best possible shortening of the time period for the running-in process can be achieved.
the control when selected Run-in process via the drive assigned to the lifter roller independently of the machine speed intended for the running-in process (Machine speed) the largest possible lift strip width (handling of the lifting roller on the ink fountain roller) for adjustment.
Machine speed machine speed
the control according to the invention resetting the lift strip width from that intended for the inlet Maximum value at that provided for the current speed (machine speed) Value.
the drive for the lifting roller consists of a pair rotatable relative to each other Cam discs, which are generated by an assigned actuator the desired lift strip widths depending on the machine speed are moved, these cams are replaced by the invention Proceed in this way with the preselected run-in process, see above that the siphon roller takes the greatest possible contact time with the ink fountain roller. After the end of the running-in process is carried out by appropriate Signal generation on the part of the control according to the invention the corresponding Reset to that provided for the current machine speed Value of the lift strip.
the control of the lifter inking unit according to the invention can be done with the control station the printing press are in signal connection, so that the control room the machine speed intended for the running-in process can be preselected.
the control then takes place after selection of the running-in process and after input the desired inlet speed, the automatic setting of the maximum Lifter strip during the entire running-in process, so that the over Ink fountain roller provided color as quickly as possible to the other rollers of the Inking unit can be fed.
An inking unit 4 has an ink fountain roller 1, a lifting roller 2, one of the lifting roller 2 downstream friction roller 3 and further rollers.
the over the Ink fountain roller 1 and remotely controllable dosing elements having ink fountain 14 color supplied to the inking unit 4 can be switched on and off Ink application rollers 5 applied to the printing plate stretched around the plate cylinder 8.
the figure also shows a dampening unit 6 with an on and off stored dampening roller 7.
the back and forth between the ink fountain roller 1 and the friction roller 3 Lifter roller 2 has a drive 13, which with the invention Controller 12 is in signal connection.
the lifter roller can be driven by the drive 13 2 in terms of both frequency and contact time (investment time) with respect to ink fountain roller 1 and friction roller 3 can be set.
the control 12 is also operatively connected to the drive 11 of the printing press, so that can be generated by the controller 12 machine speed-dependent signals are so that during the printing operation the jack roller 2 one of the machine speed (Print speed) dependent color strips (Lift strip width) decreases from the ink fountain roller 1 and this amount of ink passes to the friction roller 3 and the other rollers of the inking unit 4.
the controller 12 is also available with the actuating means, not shown, for switching on and off Parking the inking rollers 5, the dampening roller 7 and that Pressure switching of the blanket cylinder 9 effecting gear in operative connection.
actuating means not shown
the controller 12 corresponding control commands to interact with the ink fountain 14 remotely controllable dosing elements directed so that on the ink fountain roller 1 the metering profile provided for the inlet comes to the setting.
the controller 12 also generates corresponding control commands for the drive 13 of the jack roller 2, so that the largest possible jack strip width (contact time Lifter roller 2 on ink fountain roller 1) comes to the setting.
the controller 12 becomes dependent on the run-in process otherwise during printing the machine speed caused tracking of the lifting speed canceled and the lift strip width via the drive 13 to the maximum value booted.
the drive strip width of the lifting roller 2 is the lifting strip width back to the one intended for the current machine speed Value shut down. You can then switch accordingly the inking rollers 5, the dampening roller 7 and starting the blanket cylinder 9 on the plate cylinder 8 thus the impression cylinder 10 the first and the other sheets are printed.
