Description
Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Beeinflussung der Farbverteilung in Heberfarbwerken von Druckmaschinen.The invention relates to a method and a device for influencing the color distribution in jack inking units of printing machines.
Es sind Heberfarbwerke bekannt (EP 040 3861 A1), die eine in einem Farbkasten umlaufende
Duktorwalze und einen mit der Duktorwalze und einem Reibzylinder in Wirkverbindung
stehenden Farbheber aufweisen.
Der Reibzylinder ist Bestandteil des Walzenstuhles des Farbwerkes. Der Farbheber schwingt
periodisch zwischen Duktorwalze und Reibzylinder hin und her und überträgt einen Farbstreifen
von der Duktorwalze auf den Reibzylinder. Die Länge des Farbstreifens ist abhängig
von der Anlagezeit des Farbhebers am Farbduktor und der Rotationsgeschwindigkeit des
Farbduktors.Lifter inking units are known (EP 040 3861 A1) which have a duct roller which rotates in an ink fountain and an ink lifter which is operatively connected to the duct roller and a distribution cylinder.
The distribution cylinder is part of the roller unit of the inking unit. The ink lifter periodically swings back and forth between the doctor roller and the distribution cylinder and transfers an ink strip from the duct roller to the distribution cylinder. The length of the color strip depends on the time the ink lifter has been in contact with the ink roller and the speed of rotation of the ink roller.
Es ist ein Effekt der Farbverteilung in Heberfarbwerken von Druckmaschinen allgemein bekannt, wobei unter Farbverteilung sowohl das Fördern von Überschußfarbe von den Walzen des Heberfarbwerkes in den Farbkasten bei Auftragsende als auch das Fördern von Zusatzfarbe zur Erreichung eines neuen Farbprofils, aufbauend auf dem alten Farbprofil, bzw. die Kombination beider Fördermöglichkeiten verstanden wird.An effect of the color distribution in siphon inking units of printing machines is generally known, with ink distribution both conveying excess ink from the rollers the lifter inking unit in the ink fountain at the end of the order as well as the conveyance of additional ink to achieve a new color profile, based on the old color profile, or the combination of both funding options is understood.
Bei einem Verfahren gemäß der DE-OS 37 07 695 wird unter Ausnutzung dieses Effektes zunächst das vom vorhergehenden Druckauftrag im Farbwerk vorhandene Farbprofil bei sich drehender Maschine durch Schließen der Farbdosierelemente und durch Rücktransport der zonal im Farbwerk profilabhängig vorhandenen Farbmengen in den Farbkasten nach einer bestimmten Anzahl von Umdrehungen bis auf eine auf allen Walzen gleichmäßig geringe, definierte und profilunabhängige Farbschichtdicke abgebaut und danach das für den nachfolgenden Druckauftrag im Farbwerk benötigte, auftragsentsprechende Farbprofil durch zonenweises Einstellen der Farbdosierelemente, durch Einstellen der Länge des in das Farbwerk zu übertragenden Farbstreifens und durch eine definierte Anzahl von Farbwerksumdrehungen aufgebaut In a method according to DE-OS 37 07 695 is using this effect First the color profile from the previous print job in the inking unit rotating machine by closing the ink metering elements and by returning the zonal in the inking unit, depending on the profile, existing ink quantities in the ink fountain after one certain number of revolutions except for one that is evenly small on all rollers, defined and profile-independent ink layer thickness and then that for the subsequent one Print order in the inking unit required, corresponding color profile by zone Setting the ink metering elements, by adjusting the length of the inking unit to be transferred color strip and by a defined number of inking unit revolutions built up
Nachteilig ist dabei, daß die Beeinflussung der Farbverteilung in Heberfeuchtwerken infolge der diskontinuierlichen Arbeitsweise des Farbhebers ein zeitaufwendiger Prozeß ist.The disadvantage here is that the influence on the color distribution in lifter dampening systems as a result the discontinuous operation of the ink lifter is a time-consuming process.
Aus den "PATENT ABSTRACTS OF JAPAN vol. 6, no. 213 (M-167), 26.10.1982 & JP 57 120443 ist eine Einrichtung bekannt geworden, die aus Farbduktor, einem farbabnehmenden Reibzylinder und einem zwischen Farbduktor und Reibzylinder hin- und herschwingenden Farbheber besteht Der Farbheber ist an einem Ende eines Hebels gelagert und dem anderen Ende des Hebels ist eine mit einer Kurve zusammenwirkende Kurvenrolle zugeordnet. Zur Herstellung einer Wirkverbindung zwischen Farbduktor, Farbheber und Reibzylinder sowie zur Aufhebung der Wirkverbindung zwischen Kurvenrolle und Kurve wird der Hebel verschoben. Die dann vorhandene Wirkverbindung zwischen Farbduktor, Farbheber und Reibzylinder besteht darin, dass der während des Maschinenlaufs hin- und hergehenden Farbheber nun in eine Stellung steht, in der ein ständiger Kontakt zwischen dem Farbduktor und dem farbabnehmenden Reibzylinder vorliegt. Eine derartige Stellung wird gebraucht, um beim Waschen des Farbwerkes den Farbheber und den Farbduktor einzubeziehen. Diese Veröffentlichung liefert keine Anregung, die Farbverteilung bei Heberfeuchtwerken zu beeinflussen.From "PATENT ABSTRACTS OF JAPAN vol. 6, no. 213 (M-167), October 26, 1982 & A device has become known from JP 57 120443, which consists of a ink ductor, an ink-removing device Distribution cylinder and a oscillating between the ink duct and distribution cylinder Ink lifter exists The ink lifter is supported at one end of a lever and the other end of the lever is associated with a cam roller cooperating with a cam. For establishing an active connection between the ink fountain pen, ink lifter and distribution cylinder and to remove the active connection between the cam roller and the cam Lever shifted. The then existing operative connection between ink ductor and ink lifter and distribution cylinder is that of the reciprocating during the machine run Ink lifter is now in a position in which there is constant contact between the ink fountain pen and the ink-removing distribution cylinder is present.

Die Überschußfarbe wird nunmehr von den Walzen in Richtung Farbkasten gefördert (Ausgleich Farbschichtdicken).The excess ink is now conveyed by the rollers towards the ink fountain (Compensation of ink layer thicknesses).
Nachdem die Überschußfarbe in den Farbkasten zurückgefördert worden ist wird die Geschwindigkeit des Farbduktors und des Reibzylinders wieder auf die für den Druckprozeß erforderliche Geschwindigkeit gebracht.After the excess paint has been fed back into the paint box, the Speed of the ink ductor and the distribution cylinder back to that for the Speed brought to the printing process.
Gleichzeitig wird die ursprüngliche Funktion des Farbhebers wieder aktiviert.At the same time, the original function of the ink lifter is reactivated.
Mit diesen Verfahrensschritten wird erreicht daß Überschußfarbe auf schnellstem Wege, d.h. innerhalb weniger Umdrehungen in den Farbkasten zurückgefördert wird.With these process steps, excess paint is achieved as quickly as possible, i.e. is returned to the ink fountain within a few turns.
Soll gleichzeitig bei Auftragwechsel das Farbprofil gewechselt (neues Farbprofil) werden sind folgende Verfahrensschritte erforderlich.If the color profile is to be changed at the same time as the order is changed (new color profile) the following process steps are required.
