Abstract
Description
Die Erfindung betrifft ein Verfahren zur Farbwerksteuerung sowie eine Vorrichtung zur Durchführung des Verfahrens gemäß dem Oberbegriff des Verfahrens- bzw. Vorrichtungsanspruchs.The invention relates to a method for inking unit control and an apparatus for performing the method according to the preamble of the process or device claim.
Bei Bogenoffsetdruckmaschinen erfolgt die Farbzufuhr über eine mit einem Farbkasten zusammenwirkende Farbkastenwalze, eine Heberwalze sowie nachfolgende Farb- und Farbauftragwalzen. Durch die Vielzahl von Spaltvorgängen im Farbwerk erfährt die Druckfarbe eine Konditionierung, d.h. sie wird in einen für den Druck optimalen rheologischen Zustand versetzt. Die rheologischen Eigenschaften der Druckfarbe hängen von der Temperatur ab, so dass bei Änderung der Temperatur im Farbwerk bei unverändert eingestellter Farbdosierung (Drehzahl Duktor, Taktfrequenz Heberwalze, Einstellung Farbdosierelemente) sich die Farbschichtdicken auf den Walzen und dem Bedruckstoff ändern.In sheetfed offset presses, the ink is fed via an ink fountain roller interacting with an ink fountain, a siphon roller and subsequent ink and ink application rollers. Experienced by the large number of splitting processes in the inking unit the printing ink a conditioning, i.e. she will in an optimal rheological condition for printing. The rheological properties of the printing ink depend on the Temperature down, so that when the temperature changes in the inking unit with unchanged color metering (speed Ductor, cycle frequency lifter roller, setting of ink metering elements) the ink layer thicknesses on the rollers and the Change substrate.
Aus der DE 43 12 459 C2 ist eine Messeinrichtung zum Erfassen der Temperatur eines Farbwerkes von Druckmaschinen bekannt. Es wird die aus einem Raum im Bereich der Farbwerkwalzen abgesaugte Luft über einen Temperaturmessfühler geleitet, dessen Signale dann zum Steuern einer Temperiereinrichtung verwendet werden. Durch die Temperiereinrichtung ist es möglich, die Farbwerkswalzen und die darauf befindliche Druckfarbe auf ein vorgesehenes Temperaturniveau zu verbringen und insbesondere eine optimale Drucktemperatur einzustellen. Nachteilig ist hierbei aber, das Temperiereinrichtungen zum einen sehr aufwendig sind und zum anderen auch die gewünschte Temperatur erst nach einer bestimmten Zeit erreichbar ist.DE 43 12 459 C2 describes a measuring device for detection the temperature of an inking unit of printing machines is known. It becomes the one room in the area of the inking rollers extracted air passed through a temperature sensor, whose signals are then used to control a temperature control device be used. Through the tempering device it is possible, the inking rollers and the one located on them Spend ink at an intended temperature level and in particular to set an optimal printing temperature. The disadvantage here, however, is the temperature control devices are very complex on the one hand and the desired one on the other Temperature can only be reached after a certain time is.
Wegen der großen Anzahl von Farbwalzen im Farbwerk einer Bogenoffsetdruckmaschine nimmt das Farbwerk eine große Farbmenge auf weswegen diese Systeme relativ träge reagieren. Insbesondere bei Schichtbeginn bzw. bei einem Auftragwechsel ist zur Vermeidung von Anlaufmakulatur nötig, einen Farbeinlauf durchzuführen und in einem sich diesem Prozess überlagernden bzw. anschließenden weiteren Vorgang eine derartige Schichtdickenstufung auf den Walzen zu erzeugen, wie sie im späteren Druck auch vorliegt (Farbvoreinstellung).Because of the large number of inking rollers in the inking unit Sheet-fed offset press, the inking unit takes a large amount of ink to which these systems react relatively sluggishly. Especially at the start of a shift or when changing jobs a color run-in is necessary to avoid start-up waste and in an overlapping process or subsequent further process such To produce layer thickness gradation on the rollers, as in later printing is also available (color presetting).
Aus der DE 33 38 143 A1 sowie der DE 198 57 218 A1 sind Farbeinlauf- und Farbvoreinstellmethoden bekannt, wie sie zu Druckbeginn bzw. bei Auftragwechsel angewendet werden. Diese Verfahren bieten aber nur dann eine bestmögliche Reduktion der Anlaufmakulatur nach Schichtbeginn bzw. einem Auftragwechsel, wenn die in das Farbwerk eingefüllte Farbe sowie die Einstellungen an der Farbdosierung einerseits exakt an das zu verdruckende Motiv als auch an die sonstigen Maschinenparameter angepasst sind.From DE 33 38 143 A1 and DE 198 57 218 A1 Ink and ink presetting methods are known as to Start of printing or when changing jobs. This However, processes only offer the best possible reduction the start-up waste after the start of a shift or an order change, if the color filled in the inking unit and the Settings on the color dosage on the one hand exactly to the printing motif as well as to the other machine parameters are adjusted.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zur Steuerung eines Farbwerkes sowie eine Vorrichtung zur Durchführung des Verfahrens nach dem Oberbegriff des Verfahrens- bzw. Vorrichtungsanspruches derartig zu erweitern, so dass eine Makulatur spürbar reduzierende und vorzugsweise auch automatische Füllung und Voreinstellung eines Farbwerkes möglich ist.The object of the present invention is therefore a method for controlling an inking unit and a device for Execution of the procedure according to the preamble of the procedure or device claim to expand in such a way that waste is noticeably reducing and preferably also automatic filling and presetting of an inking unit is possible.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Verfahrens- bzw. Vorrichtungsanspruches. Weiterbildungen der Erfindung ergeben sich aus den jeweiligen Unteransprüchen.This task is solved by the characteristic features of the process or device claim. further developments the invention result from the respective subclaims.

Es ist vorgesehen, die Einstellungen für das Vorfüllen und/oder das Voreinstellen in Abhängigkeit der Farbwerkstemperatur zu wählen, wozu ein oder mehrere Temperatursensoren im Farbwerk angeordnet sind. Temperaturwerte können alternativ auch über die Laufzeit der Maschine (Historie) abgeleitet werden. Dazu wird die Laufzeit der Maschine in Verbindung mit weiteren Parametern erfasst und es wird insbesondere empirisch berücksichtigt, welche Temperatur das Farbwerk aufweist, wenn die Druckmaschine zuvor eine bestimmte Zeit in einer bestimmten Betriebsweise gefahren wurde.It is intended to prefill the settings and / or presetting depending on the inking unit temperature to choose, why one or more temperature sensors are arranged in the inking unit. Alternatively, temperature values can be used also derived over the life of the machine (history) become. To do this, the runtime of the machine is linked to other parameters and it is particularly empirical takes into account the temperature of the inking unit, if the press has been in for a period of time a certain mode of operation.
Die erfindungsgemäß vorgesehene temperaturabhängige Vorfüllung und/oder Voreinstellung des Farbwerkes erfolgt durch Variationen derjenigen Einstellungen, welche beim Vorfüllen bzw. Voreinstellen des Farbwerkes vorgenommen werden. Hier ist insbesondere nach der Erfindung vorgesehen, die in das Farbwerk einzubringende Farbmenge temperaturabhängig zu gestalten und dazu durch Modellrechnung gebildete bzw. empirisch erfasste Zusammenhänge zugrunde zu legen, die wiedergeben, wie bei einer gegebenen Temperatur die Farbdosierung, die Heberwalze usw. eingestellt werden muss.The temperature-dependent pre-filling provided according to the invention and / or the inking unit is preset by Variations of the settings that are used when priming or pre-setting the inking unit. Here is particularly provided according to the invention, which in the Ink quantity to be introduced depends on the temperature design and to do this, formed by model calculation or empirically to use recorded relationships that reflect like the dose of paint at a given temperature, the jack roller, etc. must be adjusted.
Da während des Druckes die Farbschichtdicke und somit die Farbdichte auf dem Bedruckstoff mit der Temperatur zunimmt, wird auch die Farbmenge, die beim Vorfüllen und Voreinstellen die in das Farbwerk einzubringen ist, entsprechend von der Temperatur im Farbwerk abhängig gemacht. Dieser Zusammenhang wird durch Modellrechnung bzw. durch Versuche bestimmt. Somit ist also eine Kennlinie ermittelbar, die wiedergibt, welche Farbmenge bei welcher Farbwerkstemperatur in das Farbwerk einzubringen ist. Nun können die Einstellparameter für beispielsweise die Farbdosierelemente, für die Farbkastenwalze (Drehzahl), die Heberwalze (Frequenz) und weitere die Farbzufuhr bestimmende Stellglieder bestimmt werden. Diese Parameter für die Voreinstellung und/oder Vorbefüllung können gemäß einer weiteren Ausführungsform der Erfindung vorzugsweise in Abhängigkeit des Sujets, d.h. dem Anteil druckender Fläche gewählt werden. Dies erfolgt vorzugsweise durch eine Unterteilung in Klassen mit geringem Anteil druckender Fläche, mittlerem Anteil druckender Fläche, hohem Anteil druckender Fläche.Since the color layer thickness and thus the Color density on the substrate increases with temperature, will also be the amount of paint used during priming and presetting which is to be brought into the inking unit, according to the Temperature in the inking unit made dependent. This connection is determined by model calculation or by tests. Consequently a characteristic curve can thus be determined which represents which Ink quantity at which inking unit temperature in the inking unit is to be brought in. Now the setting parameters for, for example the ink metering elements, for the ink fountain roller (Speed), the siphon roller (frequency) and others the ink supply determining actuators are determined. These parameters for presetting and / or pre-filling can be carried out in accordance with a further embodiment of the invention preferably in Dependence of the subject, i.e. the proportion of printing area to get voted. This is preferably done by subdivision in classes with a small amount of printing area, medium proportion of printing area, high proportion of printing Area.
Gemäß einer Ausführungsform der Erfindung wird ein gegebenes Programm zum automatischen Vorbefüllen und Voreinstellen eines Farbwerkes zugrunde gelegt. Dies besteht beispielsweise aus einer bestimmten Abfolge von Einstellungen an den Farbdosierelementen gegenüber der Farbkastenwalze, dem Betreiben der Farbkastenwalze mit einer bestimmten Anzahl von Umdrehungen und mit gegebener Drehzahl, dem Betreiben der Heberwalze mit einer bestimmten Anzahl Takten und vorgegebener Frequenz sowie beispielsweise dem gezielten Schalten von Stellgliedern für die Farbzugtrennung (Unterbrechung des Walzenzuges). Nach der Erfindung ist nun vorgesehen, beispielsweise ausschließlich die Anzahl der Hebertakte, durch welche Farbe von der Farbkastenwalze in den unteren Teil des Farbwerkes transportiert wird, in Abhängigkeit der Farbwerkstemperatur zu variieren. Auch kann gemäß einer Ausführungsform der Erfindung vorgesehen sein, durch Einstellung der Duktordrehzahl (Farbkastenwalze) die in das Farbwerk hinein zu fördernde Farbmenge temperaturabhängig zu gestalten oder über eine Einstellung der Farbdosierelemente gegenüber der Farbkastenwalze die Menge des in das Farbwerk hinein zu fördernde Druckfarbe in Abhängigkeit der Farbwerkstemperatur vorzunehmen. According to one embodiment of the invention, a given Program for automatic pre-filling and pre-setting based on an inking system. This is the case, for example from a certain sequence of settings on the color metering elements compared to the ink fountain roller, the operation the ink fountain roller with a certain number of revolutions and at a given speed, the operation of the lifting roller with a certain number of cycles and a predetermined frequency and, for example, the targeted switching of actuators for color separation (interruption of the roller train).

Bei einer Farbvoreinstellung, bei welcher zu bestimmten Zeiten der Farbwalzenzug getrennt bzw. wieder zusammen geschaltet wird, können die Zeitintervalle in Abhängigkeit der Farbwerkstemperatur gewählt werden. Die entsprechenden Einstellwerte werden durch Modellrechnung bestimmt bzw. empirisch festgelegt. In vorteilhafter Weise kann dies dadurch erfolgen, dass durch Probedrucke festgestellt wird, wie sich die Farbdichte in Abhängigkeit der Temperatur ändert. Daraus ist dann ein Korrekturfaktor berechenbar, der angibt, wie ein entsprechender Einstellungswert zu verändern ist, um einer Abnahme der Farbschichtdicke bei abnehmender Temperatur entgegen zu wirken. Somit sind Kennlinien ermittelbar und werden in einem der Steuerung des Farbwerkes zugeordneten Speicher abgelegt.With a color preset, with which to determine Times the inking roller separately or switched together again the time intervals depending on the Inking unit temperature can be selected. The corresponding setting values are determined by model calculation or empirically established. This can be done in an advantageous manner take place that test prints determine how the color density changes depending on the temperature. from that a correction factor can then be calculated, which indicates how a corresponding setting value is to be changed to one Decrease in the color layer thickness with decreasing temperature to counteract. Characteristic curves can thus be determined are assigned to the control of the inking unit Memory stored.
