Description

Verfahren und Einrichtung zur Beeinflussung der FarbverteilungMethod and device for influencing the color distribution
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 lift inking units of printing machines.
Es sind Heberfarbwerke bekannt (EP 0403861 A1), die eine in einem Farbkasten umlaufende Duktorwalze und einen mit der Duktorwalze und einem Reibzylinder in Wirkverbindung stehenden Farbheber aufweisen.Lifter inking units are known (EP 0403861 A1), which have a ductor roller rotating in an ink fountain and an ink lifter that is operatively connected to the ductor roller and a distribution cylinder.
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.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 presses is generally known, whereby under color distribution both the conveyance of excess ink from the rollers of the siphon inking unit into the ink fountain at the end of the order and 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 3707695 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 3707695, using this effect, the color profile from the previous print job in the inking unit is first turned on the machine when the machine is rotating by closing the ink metering elements and by returning the ink quantities present in the inking unit depending on the profile to the ink fountain after a certain number of revolutions apart from a uniformly small, defined and profile-independent ink layer thickness on all rollers and then the color profile required for the subsequent print job in the inking unit by zone-by-zone adjustment of the ink metering elements, by adjusting the length of the ink strip to be transferred to the inking unit and by a defined number of Ink 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 influencing the ink distribution in lifter dampening systems is a time-consuming process due to the discontinuous mode of operation of the ink lifter.
Aufgabe der Erfindung ist die Schaffung eines Verfahrens und einer Einrichtung zur Beeinflussung der Farbverteilung in Druckmaschinen in kurzer Zeit. Die Aufgabe wird erfindungsgemäß durch die Patentansprüche gelöst; zweckmäßige Ausgestaltungen sind in den Unteransprüchen offenbart.The object of the invention is to create a method and a device for influencing the color distribution in printing machines in a short time. The object is achieved by the claims; expedient configurations are disclosed in the subclaims.
Nachfolgend wird die Erfindung an einem Ausführungsbeispiel näher beschrieben. In der Zeichnung ist ein Heberfarbwerk einer Druckmaschine dargestellt. Anhand dieser Zeichnung werden die erfindungsgemäßen Verfahrensschritte näher erläutert. Das Heberfarbwerk besteht aus einem Farbkasten 1 , mit einem Farbduktor 2, einem Farbheber 3, einem Reibzylinder 4 und einem dem Reibzylinder 4 nachgeordneten, mehrere Walzen 5 enthaltenden Walzenstuhl 6.The invention is described in more detail below using an exemplary embodiment. In the drawing, a lifter inking unit of a printing press is shown. The method steps according to the invention are explained in more detail with reference to this drawing. The lifter inking unit consists of an ink fountain 1, with an ink fountain roller 2, an ink lifter 3, a distribution cylinder 4 and a downstream of the distribution cylinder 4, containing several rollers 5.
Der Farbkasten 1 ist mit motorisch angetriebenen Farbprofilstelleinrichtungen 7 ausgestattet. Der Farbduktor 2 ist mit einem Antriebsmotor 8 verbunden, der den Farbduktor schrittweise und kontinuierlich mit unterschiedlicher Geschwindigkeit antreiben kann. Der Reibzylinder 4 ist mit einem nicht dargestellten Antriebsrad ausgestattet, welches Bestandteil des Antriebsräderzug der Druckmaschine ist, d.h. die Geschwindigkeit des Reibzy- iinders ist über die Geschwindigkeit der Druckmaschine veränderbar. Der Farbheber 3 ist in einem ersten Hebelarm 9' eines Winkelhebels 9 gelagert. Der zweite Hebelarm 9" des Winkelhebels 9 trägt eine Kurvenrolle 10, die mit einer Kurve 11 in Wirkverbindung steht.The ink fountain 1 is equipped with motor-driven ink profile adjusting devices 7. The ink duct 2 is connected to a drive motor 8 which can drive the ink duct step by step and continuously at different speeds. The distribution cylinder 4 is equipped with a drive wheel, not shown, which is part of the drive wheel train of the printing press, i.e. the speed of the friction cylinder can be changed via the speed of the printing press. The paint lifter 3 is mounted in a first lever arm 9 'of an angle lever 9. The second lever arm 9 "of the angle lever 9 carries a cam roller 10 which is operatively connected to a cam 11.
Der Winkelhebel 9 ist in einem Drehpunkt 12 gelagert. Dieser Drehpunkt 12 ist wiederum in einem mit einem Betätigungsglied 14 verbundenen Schwenkhebel 13 angeordnet. Die geometrischen Verhältnisse der Anordnung des Winkelhebels und des Schwenkhebels sind so ausgelegt, daß die Herstellung der Wirkverbindung zwischen Farbduktor/Farbheber/ Reibzylinder mit der Trennung der Kurvenrolle 10 von der Kurve 11 verbunden ist. Alternativ ist auch die Sperrung der Kurvenrolle 10 mittels einer Sperrklinke 16 über ein Bewegungselement 15 möglich.The angle lever 9 is mounted in a pivot point 12. This pivot point 12 is in turn arranged in a pivot lever 13 connected to an actuating member 14. The geometric relationships of the arrangement of the angle lever and the swivel lever are designed such that the production of the operative connection between the ink duct / ink lifter / distribution cylinder is connected with the separation of the cam roller 10 from the cam 11. Alternatively, the cam roller 10 can also be locked by means of a pawl 16 via a movement element 15.
Der Verfahrensablauf zur reaktionsschnellen Beeinflussung der Farbverteilung umfaßt folgende Verfahrensschritte.The process sequence for quickly influencing the color distribution comprises the following process steps.
Der Farbduktor 2 wird auf maximale Geschwindigkeit beschleunigt; dazu wird der Antriebsmotor 8 entsprechend angesteuert.The ink fountain roller 2 is accelerated to maximum speed; the drive motor 8 is controlled accordingly.
Der Reibzylinder 4 wird nunmehr auf eine Geschwindigkeit gebracht, der der Geschwindigkeit des Farbduktors entspricht. Dies erfolgt durch Geschwindigkeitsangleichung der Druckmaschine. Der Farbheber 3 wird in Wirkverbindung sowohl mit dem Farbduktor 2 als auch mit dem Reibzylinder 4 gebracht (gestrichelte Darstellung in der Zeichnung). Gleichzeitig wird die Kurvenrolle 10 von der Kurve 11 weggesteuert und damit der Schwingantrieb für den Farbheber stillgesetzt.The distribution cylinder 4 is now brought to a speed which corresponds to the speed of the ink ductor. This is done by adjusting the speed of the printing press. The ink lifter 3 is brought into operative connection both with the ink ductor 2 and with the distribution cylinder 4 (dashed illustration in the drawing). At the same time, the cam roller 10 is steered away from the cam 11 and the vibratory drive for the ink lifter is thus stopped.
Diese Operationen werden durch das Betätigungsglied 14 eingeleitet. Alternativ ist auch die Herstellung einer Wirkverbindung zwischen Farbduktor, Farbheber und Reibzylinder durch Verschieben und/oder Verschwenken des Farbkastens einschließlich Farbduktor in Richtung Farbheber möglich.These operations are initiated by the actuator 14. Alternatively, it is also possible to establish an operative connection between the ink duct, ink lifter and distribution cylinder by moving and / or pivoting the ink fountain including ink duct in the direction of the ink lifter.
Vermittels der Farbprofileinstelleinrichtung 7 wird der Farbkasten 1 geschlossen, so daß keine Farbe zu den nachfolgenden Walzen gefördert wird.The ink fountain 1 is closed by means of the ink profile adjusting device 7, so that no ink is conveyed to the subsequent rollers.
Die Überschußfarbe wird nunmehr von den Walzen in Richtung Farbkasten gefördert (Ausgleich Farbschichtdicken).The excess ink is now conveyed by the rollers in the direction of 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 ink has been fed back into the ink fountain, the speed of the ink ductor and the distribution cylinder are brought back to the speed required for 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 it is achieved that excess paint in the quickest way, 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.
Der Farbduktor 2 wird auf maximale Geschwindigkeit beschleunigt; dazu wird der Antriebsmotor 8 entsprechend angesteuert.The ink fountain roller 2 is accelerated to maximum speed; the drive motor 8 is controlled accordingly.
Der Reibzylinder 4 wird nunmehr auf eine Geschwindigkeit gebracht, der der Geschwindigkeit des Farbduktors entspricht. Dies erfolgt durch Geschwindigkeitserhöhung der Druckmaschine. Der Farbheber 3 wird in Wirkverbindung sowohl mit dem Farbduktor 2 als auch mit dem Reibzylinder 4 gebracht (gestrichelte Darstellung in der Zeichnung). Gleichzeitig wird die Kurvenrolle 10 von der Kurve 11 weggesteuert und damit der Schwingantrieb für den Farbheber stillgesetzt.The distribution cylinder 4 is now brought to a speed which corresponds to the speed of the ink ductor. This is done by increasing the speed of the printing press. The ink lifter 3 is brought into operative connection both with the ink ductor 2 and with the distribution cylinder 4 (dashed illustration in the drawing). At the same time, the cam roller 10 is steered away from the cam 11 and the vibratory drive for the ink lifter is thus stopped.
Diese Operationen werden durch das Betätigungsglied 14 eingeleitet.These operations are initiated by the actuator 14.
Auch hier ist alternativ das Verschieben und/oder Verschwenken des Farbkastens, wie bereits beschrieben, möglich.Here too, as an alternative, moving and / or pivoting the ink fountain is possible, as already described.
Das neue Farbprofil wird vermittels der Farbprofileinstelleinrichtung 7 am Farbkasten 1 eingestellt.The new color profile is set by means of the color profile setting device 7 on the ink fountain 1.
Ist Überschußfarbe vorhanden wird diese nunmehr von den Walzen in Richtung Farbkasten gefördert (Ausgleich Farbschichtdicken). Ist entsprechend des neuen Farbprofils Zusatzfarbe auf den Walzen erforderlich wird diese vom Farbduktor zu den Walzen gefördert. Dabei laufen die beiden genannten Prozesse je nach Erfordernis auch gleichzeitig ab.If there is excess ink, this is now conveyed by the rollers in the direction of the ink fountain (compensation of ink layer thicknesses). If additional ink is required on the rollers in accordance with the new color profile, this is conveyed to the rollers by the ink ductor. The two processes mentioned can also run simultaneously, as required.
Nachdem dieser Prozeß abgeschlossen ist wird die Geschwindigkeit des Farbduktors und des Reibzylinders wieder auf die für den Druckprozeß erforderliche Geschwindigkeit gebracht.After this process is completed, the speed of the ink ductor and the distribution cylinder are brought back to the speed required for 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.
Ist in dem verwendeten Walzenstuhl 6 eine bekannte Farbwalzentrennung bei Druckunterbrechung integriert, so ist es zweckmäßig bei den beschriebenen Verfahrensschritten diese Walzentrennung aufzuheben.If a known inking roller separation is integrated in the roller mill 6 used when printing is interrupted, it is expedient to remove this roller separation in the method steps described.
Des weiteren ist es zweckmäßig die nicht dargestellten Farbauftragwalzen bei diesem Prozeß von dem Druckformzylinder abzustellen.
