Beide obigen Aspekte können entweder alleine oder auch in Kombination miteinander bei Druckmaschinen zur Anwendung kommen.Both of the above aspects can be used either alone or in combination with printing presses.
Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, nachfolgend näher erläutert.Further developments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be explained in more detail below, without being limited thereto.
Die hier vorliegende Erfindung betrifft ein Verfahren zum Betreiben einer Druckmaschine, nämlich zur Durchführung eines fliegenden Druckplattenwechsels an mindestens einem Druckwerk einer Bogendruckmaschine, während andere Druckwerke der Bogendruckmaschine im Fortdruck betrieben werden.The present invention relates to a method for operating a printing press, namely for performing a flying printing plate change on at least one printing unit of a sheet-fed press, while other printing units of the sheet-fed printing press are operated in the production.
Bogendruckmaschinen verfügen über mehrere Druckwerke, wobei in jedem der Druckwerke ein Teildruckbild auf Druckbogen aufgetragen wird. Jedes der Druckwerke verfügt über einen Gegendruckzylinder, einen auf dem Gegendruckzylinder abrollenden Gummizylinder und einen auf dem Gummizylinder abrollenden Formzylinder, wobei auf dem Gummizylinder ein Gummituch und auf dem Formzylinder eine Druckform positioniert ist. Weiterhin verfügt jedes Druckwerk über ein Farbwerk sowie im bevorzugten Ausführungsbeispiel auch über ein Feuchtwerk. Mithilfe des Farbwerks wird Druckfarbe auf die auf dem Formzylinder positionierte Druckform aufgetragen. Mithilfe des Feuchtwerks wird Feuchtmittel auf die auf dem Formzylinder positionierte Druckform aufgetragen.Sheetfed presses have several printing units, each of the printing units a partial print image is applied to sheet. Each of the printing units has an impression cylinder, a rolling on the impression cylinder blanket cylinder and a rolling cylinder on the blank cylinder, wherein on the blanket cylinder a blanket and on the forme cylinder is positioned a printing forme. Furthermore, each printing unit has an inking unit and in the preferred embodiment also has a dampening unit. The inking unit applies ink to the printing block positioned on the plate cylinder. Moistening agent is applied to the printing block positioned on the forme cylinder with the aid of the dampening unit.
Ausgehend vom Formzylinder wird die Druckfarbe auf den Gummizylinder und ausgehend vom Gummizylinder auf Druckbogen übertragen, die durch einen zwischen dem Gummizylinder und Gegendruckzylinder gebildeten Spalt hindurch gefördert werden. Die zu bedruckenden Druckbogen werden mithilfe sogenannter Transferzylinder von Druckwerk zu Druckwerk übergeben.Starting from the forme cylinder, the printing ink is transferred to the blanket cylinder and, starting from the blanket cylinder, to printing sheets, which are conveyed through a gap formed between the blanket cylinder and impression cylinder. The printed sheets to be printed are transferred from printing unit to printing unit by means of so-called transfer cylinders.
Bei derartigen Druckmaschinen werden im sogenannten Fortdruck die Transferzylinder sowie im Bereich der Druckwerke die Gegendruckzylinder, Gummizylinder, Farbwerke sowie Feuchtwerke von einem Hauptantrieb der Bogendruckmaschine angetrieben. Nachfolgend soll davon ausgegangen werden, dass den Formzylindern bzw. Plattenzylindern der Druckwerke Eigenantriebe bzw. Direktantriebe zugeordnet sind, mithilfe derer die Formzylinder im Fortdruck entkoppelt vom Hauptantrieb, jedoch synchronisiert zum Hauptantrieb, angetrieben werden.In such printing presses, the transfer cylinders and in the area of the printing units the impression cylinders, blanket cylinders, inking units and dampening units are driven by a main drive of the sheet-fed printing machine. It will be assumed below that the printing cylinders or plate cylinders of the printing units are assigned self-drives or direct drives, by means of which the forme cylinders are decoupled from the main drive but decoupled from the main drive in deceleration.
Soll nun an einem Druckwerk der Druckmaschine ein fliegender Druckplattenwechsel durchgeführt werden, während andere Druckwerke im Fortdruck betrieben werden, so werden in einem ersten Schritt an dem noch im Fortdruck betriebenen Druckwerk, an welchem nachfolgend der fliegende Druckplattenwechsel durchgeführt werden soll, die Farbauftragwalzen des Farbwerks vom Formzylinder des jeweiligen Druckwerks abgestellt, wohingegen die Feuchtauftragwalze des Feuchtwerks zuerst am Formzylinder angestellt bleibt. Formzylinder sowie Gummizylinder bleiben in einer Druckanstellung. Nach einer vorgegebenen ersten Zeitdauer bzw. einer vorgegebenen ersten Anzahl an Maschinenumdrehungen bzw. Zylinderumdrehungen nach dem Abstellen der Farbauftragwalzen vom Formzylinder wird auch die Feuchtauftragwalze vom Formzylinder abgestellt, Formzylinder und Gummizylinder bleiben jedoch weiterhin in Druckanstellung. Im Anschluss hieran werden in einem weiteren Schritt des erfindungsgemäßen Verfahrens nach einer vorgegebenen zweiten Zeitdauer bzw. einer vorgegebenen zweiten Anzahl an Maschinenumdrehungen bzw. Zylinderumdrehungen nach dem Abstellen der Feuchtauftragwalze vom Formzylinder der Formzylinder und der Gummizylinder in eine Druckabposition überführt.If a flying printing plate change is now to be carried out on a printing unit of the printing machine, while other printing units are operated in the production run, then the inking rollers of the inking unit of. Are to be performed in a first step on the printing unit still being operated in the continuous printing on which subsequently the flying printing plate change Shut down form cylinder of the respective printing unit, whereas the dampening roller of the dampening system is first employed on the forme cylinder. Form cylinder and blanket cylinder remain in a pressure position. After a predetermined first time or a predetermined first number of machine revolutions or cylinder revolutions after stopping the inking rollers from the forme cylinder and the dampening form roller is parked from the forme cylinder, but form cylinder and blanket cylinder remain in pressure position. Following this, in a further step of the method according to the invention, after a predetermined second period of time or a predetermined second number of machine revolutions or cylinder revolutions, after stopping the dampening form roller, the forme cylinder and the blanket cylinder are transferred to a print position.
Während der vorgegebenen ersten Zeitdauer sowie der vorgegebenen zweiten Zeitdauer bzw. während der vorgegebenen ersten Anzahl an Zylinderumdrehungen und der vorgegebenen zweiten Anzahl an Zylinderumdrehungen, für welche Formzylinder und Gummizylinder des Druckwerks, an welchem ein fliegender Druckplattenwechsel durchgeführt werden soll, in der Druckanposition bleiben, können ein auf dem Gummizylinder gespanntes Gummituch sowie eine auf dem Formzylinder gespannte Druckplatte gereinigt werden, indem auf der Druckplatte sowie auf dem Gummizylinder befindliche Druckfarbe im Sinne eines Makulaturdrucks auf Druckbogen übertragen wird. Hierbei werden dann vorzugsweise im Bereich der Druckwerke, an welchen kein Druckplattenwechsel durchgeführt werden soll und die demnach weiterhin im Fortdruck betrieben werden sollen, Formzylinder und Gummizylinder vorübergehend in eine Druckabposition, um an diesen Druckwerken Druckfarbe und Feuchtmittel während des Makulaturdrucks bzw. des Reinigens des einem Druckplattenwechsels zu unterziehenden Druckwerks zu sparen.During the predetermined first time period and the predetermined second time period or during the predetermined first number of cylinder revolutions and the predetermined second number of cylinder revolutions for which forme cylinder and blanket cylinder of the printing unit, on which a flying pressure plate change is to be performed, remain in the pressure position can a rubber blanket stretched on the blanket cylinder and one on the Form cylinder tensioned printing plate to be cleaned by ink located on the printing plate and on the blanket cylinder is transferred in the sense of waste printing on sheet. In this case, preferably in the field of printing units to which no printing plate change is to be carried out and therefore continue to be operated in the continuous printing, forme cylinder and blanket cylinder temporarily in a print position to print at these printing units and dampening solution during waste printing or cleaning of a To save printing plate change to undergo printing unit.
Nach dem Überführen des Formzylinders sowie Gummizylinders des einem Druckplattenwechsels zu unterziehenden Druckwerks in die Druckabposition wird in einem weiteren Schritt des erfindungsgemäßen Verfahrens an diesem Druckwerk der fliegende Druckplattenwechsel durchgeführt. In etwa zeitgleich mit dem Überführen des Formzylinders und des Gummizylinders des einem Druckplattenwechsels zu unterziehenden Druckwerks in die Druckabposition werden die Formzylinder sowie Gummizylinder der weiterhin im Fortdruck zu betreibenden Druckwerke, die zwischenzeitlich in eine Druckabposition überführt wurden, wieder in die Druckanposition gebracht. Während des Fortdrucks wird dann an dem einem Druckplattenwechsel zu unterziehendem Druckwerk der fliegende Druckplattenwechsel ausgeführt, wobei hierbei das Farbwerk und das Feuchtwerk des Druckwerks entweder weiterhin vom Hauptantrieb angetrieben werden oder vom Eigenantrieb des entsprechenden Formzylinders.After the transfer of the forme cylinder and blanket cylinder of a printing plate to be subjected to changing printing unit in the printing position, the flying printing plate change is performed in a further step of the method according to the invention at this printing unit. In about the same time as the transfer of the forme cylinder and the blanket cylinder of a printing plate to be subjected printing unit in the printing position, the forme cylinder and blanket cylinders of the continue to be operated in the production printing units, which were transferred in the meantime in a print position, brought back into the printing position. During the printing process, the printing plate change is then carried out on the printing plate to be subjected printing under a change, in which case the inking unit and the dampening unit of the printing unit either continue to be driven by the main drive or the self-propelled of the corresponding forme cylinder.
Dann, wenn während des Druckplattenwechsels das Farbwerk sowie Feuchtwerk des einem Druckplattenwechsel zu unterziehenden Druckwerks vom Hauptantrieb angetrieben werden, wird das Farbwerk vorzugsweise von einem Druckfarbebehälter getrennt, so dass keine zusätzliche Druckfarbe in das Farbwerk eingebracht wird und sich demnach keine Druckfarbe im Farbwerk staut. Hierzu werden entweder alle Farbzonenstellelemente geschlossen, oder es wird eine Heberwalze bzw. Filmwalze des Farbwerks deaktiviert. In diesem Fall bleiben das Farbwerk sowie das Feuchtwerk des jeweiligen Druckwerks an den Hauptantrieb der Bogendruckmaschine gekoppelt.Then, when the inking unit and dampening unit of a printing plate to be subjected printing unit are driven by the main drive during the printing plate change, the inking unit is preferably separated from a printing ink container, so that no additional ink is introduced into the inking and thus accumulates no ink in the inking unit. For this purpose, either all Farbzonenstellelemente be closed, or it is disabled a squeegee roller or film roller of the inking unit. In this case, the inking remain as well as the dampening unit of the respective printing unit coupled to the main drive of the sheet-fed press.
In dem Fall, in welchem während der Ausführung des fliegenden Druckplattenwechsels das Farbwerk sowie Feuchtwerk des einem Druckplattenwechsels zu unterziehenden Druckwerks vom Eigenantrieb bzw. Direktantrieb des Plattenzylinders des entsprechenden Druckwerks angetrieben werden, werden Farbwerk sowie Feuchtwerk vom Hauptantrieb entkoppelt und an den Formzylinder bzw. den Eigenantrieb desselben gekoppelt. In diesem Fall werden dann das Farbwerk sowie Feuchtwerk mit einer deutlich niedrigeren Drehzahl angetrieben als die vom Hauptantrieb vorgegebene Drehzahl, so dass auch bei einem vom Druckfarbebehälter ungetrennten Farbwerk in denselben optimale Fortdruckbedingungen aufrecht erhalten werden können.In the case in which during the execution of the flying pressure plate change the inking unit and dampening of a pressure plate change to undergo printing unit are driven by the drive or direct drive of the plate cylinder of the corresponding printing unit, inking unit and dampening unit are decoupled from the main drive and to the form cylinder or self-propelled the same coupled. In this case, then the inking unit and dampening are driven at a significantly lower speed than the specified by the main drive speed, so that even with a separate ink tank from the inking unit in the same optimal conditions for continuous printing can be maintained.
Nach ausgeführtem Druckplattenwechsel werden die Farbauftragwalzen des Farbwerks sowie die Feuchtauftragwalze des Feuchtwerks an den mit der neuen Druckplatte versehenen Formzylinder angestellt, um so eine Voreinfärbung der Druckplatte zu erzielen. Bei der Voreinfärbung bleiben Gummizylinder und Formzylinder weiterhin in einer Druckabposition.After the printing plate change the inking rollers of the inking unit and the dampening roller of the dampening unit are employed on the provided with the new printing plate form cylinder, so as to achieve a pre-inking of the printing plate. During pre-inking, blanket cylinders and forme cylinders continue to be in a print position.
Nach Ausführung dieser Voreinfärbung werden dann der Formzylinder und Gummizylinder des Druckwerks in die Druckanposition überführt, um wieder in den Fortdruck eingeschaltet zu werden. Dies kann nach einer ersten Variante unmittelbar durchgeführt werden.After execution of this pre-inking of the form cylinder and blanket cylinders of the printing unit are then transferred to the printing position, to be turned on again in the print run. This can be done immediately according to a first variant.
Nach einer zweiten Variante wird dann, wenn unmittelbar im Anschluss an einem anderen Druckwerk ein fliegender Druckplattenwechsel durchgeführt werden soll, dieses nachfolgend einem Druckplattenwechsel zu unterziehende Druckwerk zuerst wiederum durch Reinigen von Gummizylinder und Formzylinder auf den Druckplattenwechsel vorbereitet.According to a second variant, if a flying printing plate change is to be carried out immediately after another printing unit, this printing unit to be subsequently subjected to a printing plate change is first prepared again by cleaning the blanket cylinder and forme cylinder on the printing plate change.
Das oben beschriebene, erfindungsgemäße Verfahren ist selbstverständlich auch dann einsetzbar, wenn an mehreren Druckwerken einer Druckmaschine während des Fortdrucks anderer Druckwerke ein fliegender Druckplattenwechsel durchgeführt werden soll.Of course, the method according to the invention described above can also be used if a flying printing plate change is to be carried out at several printing units of a printing machine during the printing of other printing units.
Mithilfe des erfindungsgemäßen Verfahrens ist ein besonders effizienter fliegender Druckplattenwechsel mit minimalem Makulaturdruck durchführbar.With the aid of the method according to the invention, a particularly efficient flying printing plate change can be carried out with minimal wastepaper pressure.
