Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Bogendruckmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for operating a sheet-fed printing press according to the preamble of claim 1.
Aus dem Stand der Technik, nämlich aus der
Bei der dort offenbarten Bogendruckmaschine werden im Fortdruckbetrieb die Gegendruckzylinder, die Übertragungszylinder, die Farbwerke sowie die Feuchtwerke der Druckwerke sowie die Bogenführungszylinder von mindestens einem Hauptantrieb der Bogendruckmaschine angetrieben. Den Formzylindern der Druckwerke sind hingegen Direktantriebe zugeordnet, welche die Formzylinder im Fortdruckbetrieb entkoppelt von dem oder jedem Hauptantrieb der Bogendruckmaschine eigenmotorisch antreiben.In the sheet-fed printing machine disclosed therein, the counter-pressure cylinders, the transfer cylinders, the inking units and the dampening units of the printing units as well as the sheet guiding cylinders are driven by at least one main drive of the sheet-fed printing machine in the continuous printing operation. The form cylinders of the printing units, however, are associated with direct drives, which decouples the form cylinder in the continuous printing operation of the or each main drive of the sheet-fed press self-propelled.
Nach der
Bislang sind keine Verfahren bekannt, mit Hilfe deren eine solche Bogendruckmaschine derart betrieben werden kann, dass Geometriefehler der Druckwerke, deren Formzylinder eigenmotorisch mit Hilfe von Direktantrieben angetrieben werden, mit hinreichender Genauigkeit ermittelt werden können.So far, no methods are known with the aid of which such a sheet-fed printing press can be operated such that geometry errors of the printing units whose form cylinders are driven by an own motor with the aid of direct drives, can be determined with sufficient accuracy.
Bei Geometriefehlern handelt es sich insbesondere um Rundlauffehler in einer Geberanbindung und/oder um kardanische Fehler in der Geberanbindung und/oder um Fehler in Folge einer Unrundheit von Schnitzringen und/oder um Fehler in Folge einer Unrundheit der Zylinderlager.Geometric errors are, in particular, concentricity errors in a sensor connection and / or cardanic errors in the encoder connection and / or errors as a result of out-of-roundness of carving rings and / or errors as a consequence of out-of-roundness of the cylinder bearings.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde ein neuartiges Verfahren zum Betreiben einer Bogendruckmaschine zu schaffen. Dieses Problem wird durch ein Verfahren gemäß Anspruch 1 gelöst.On this basis, the present invention is based on the problem to provide a novel method for operating a sheet-fed press. This problem is solved by a method according to claim 1.
Erfindungsgemäß werden zur Ermittlung eines Geometriefehlers der Druckwerke der Bogendruckmaschine die Übertragungszylinder und die Formzylinder der Druckwerke derart in eine Druckanstellung überführt, dass dieselben ausschließlich über einen Schmitzringkontakt derselben aufeinander abrollen, wobei Reglerparameter von Antriebsreglern der Direktantriebe derart eingestellt werden, dass über die Direktantriebe ein konstantes bzw. quasikonstantes Antriebsmoment in die Formzylinder eingetrieben wird, wobei Sollwerte und Istwerte der Antriebsregler der Direktantriebe und/oder Regelabweichungen zwischen den Sollwerten und den Istwerten der Antriebsregler der Direktantriebe erfasst werden, und wobei die Regelabweichungen dem Geometriefehler der Druckwerke der Bogendruckmaschine entsprechen.According to the invention, to determine a geometry error of the printing units of the sheet-fed printing press, the transfer cylinders and the forme cylinders of the printing units are transferred into a pressure position such that they roll over one another exclusively via a bearer ring contact, controller parameters of drive controllers of the direct drives being set in such a way that via the direct drives a constant or constant speed is achieved ., Quasikonstantes drive torque is driven into the form cylinder, with setpoints and actual values of the drive controller of the direct drives and / or control deviations between the setpoints and the actual values of the drive controller of the direct drives are detected, and wherein the deviations correspond to the geometry error of the printing units of the sheet-fed press.
Mit dem erfindungsgemäßen Verfahren kann ein Geometriefehler der Druckwerke, deren Formzylinder eigenmotorisch mit Hilfe von Direktantrieben angetrieben werden, genau ermittelt werden.With the method according to the invention, a geometry error of the printing units whose form cylinders are driven by an own motor with the aid of direct drives can be accurately determined.
Hierzu werden die Übertragungszylinder und die Formzylinder der Druckwerke in eine definierte Druckanstellung überführt, weiterhin werden definierte Reglerparameter für die Antriebsregler der Direktantriebe eingestellt.For this purpose, the transfer cylinder and the forme cylinder of the printing units are transferred to a defined pressure setting, further defined controller parameters for the drive controller of the direct drives are set.
Hiermit kann ein ausreichendes Maß an Gleichlauf für die Druckwerke bereitgestellt werden, wobei die Antriebsregler der Druckwerke nur in vernachlässigbarem Maße vorhandene Ungenauigkeiten ausregeln. Auf diese Art und Weise lassen sich Geometriefehler der Druckwerke direkt aus den Zustandsgrößen der Antriebsregler, nämlich aus den Istwerten und Sollwerten derselben, ablesen.This can provide a sufficient degree of synchronization for the printing units, with the drive controllers of the printing units only compensate negligibly existing inaccuracies. In this way, geometry errors of the printing units can be read directly from the state variables of the drive controllers, namely from the actual values and nominal values of the same.
Vorzugsweise werden die ermittelten Geometriefehler der Druckwerke der Bogendruckmaschine im Fortdruckbetrieb als Korrekturwert bei der Antriebsregelung verwendet.Preferably, the determined geometry errors of the printing units of the sheet-fed printing machine are used in the continuous printing operation as a correction value in the drive control.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ein Ausführungsbeispiel der Erfindung wird, ohne hierauf beschränkt zu sein, nachfolgend näher erläutert.Preferred embodiments of the invention will become apparent from the dependent claims and the description below. An embodiment 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, die mehrere Druckwerke umfasst. Jedes Druckwerk umfasst einen Gegendruckzylinder, einen auf dem Gegendruckzylinder abrollenden Übertragungszylinder, einen auf dem Übertragungszylinder abrollenden Formzylinder, ein Farbwerk sowie vorzugsweise ein Feuchtwerk.The present invention relates to a method for operating a printing press, which comprises a plurality of printing units. Each printing unit comprises an impression cylinder, a rolling on the impression cylinder transfer cylinder, a rolling on the transfer cylinder form cylinder, an inking unit and preferably a dampening unit.
Zwischen den Gegendruckzylindern benachbarter Druckwerke ist jeweils mindestens ein Bogenführungszylinder positioniert, um zu bedruckende Druckbogen durch die Druckwerke zu transportieren. Die Übertragungszylinder der Druckwerke werden auch als Gummizylinder und die Formzylinder derselben als Plattenzylinder bezeichnet.Between the counter-pressure cylinders of adjacent printing units, at least one sheet-guiding cylinder is in each case positioned in order to transport printing sheets to be printed through the printing units. The transfer cylinders of the printing units are also referred to as a blanket cylinder and the forme cylinder thereof as a plate cylinder.
Im Fortdruckbetrieb der Druckmaschine werden zumindest die Gegendruckzylinder und die Übertragungszylinder jedes Druckwerks von mindestens einem Hauptantrieb der Bogendruckmaschine angetrieben. Vorzugsweise werden im Fortdruckbetrieb die Gegendruckzylinder und die Übertragungszylinder sämtlicher Druckwerke, die zwischen den Gegendruckzylindern der Druckwerke positionierten Bogenführungszylinder sowie die Farbwerke und Feuchtwerke der Druckwerke von dem oder jedem Hauptantrieb angetrieben.In the continuous printing operation of the printing press, at least the impression cylinders and the transfer cylinders of each printing unit are driven by at least one main drive of the sheet-fed printing machine. Preferably, in the continuous printing operation, the counter-pressure cylinder and the transfer cylinder of all printing units, the sheet guiding cylinders positioned between the impression cylinders of the printing units and the inking units and dampening units of the printing units are driven by the or each main drive.
Dem Formzylinder jedes Druckwerks ist ein Direktantrieb zugeordnet, um den jeweiligen Formzylinder im Fortdruckbetrieb entkoppelt vom Hauptantrieb eigenmotorisch anzutreiben, und zwar synchron zum Übertragungszylinder.The form cylinder of each printing unit is associated with a direct drive to drive the respective form cylinder decoupled in the continuous printing operation of the main drive self-engine, in synchronism with the transfer cylinder.
Im Fortdruckbetrieb dient demnach ein Lagesignal des Übertragungszylinders des jeweiligen Druckwerks als Sollwert für den jeweiligen Antriebsregler des Direktantriebs des Formzylinders des Druckwerks.In the continuous printing operation, therefore, a position signal of the transfer cylinder of the respective printing unit serves as a setpoint for the respective drive controller of the direct drive of the forme cylinder of the printing unit.
Zur Ermittlung eines Geometriefehlers der Druckwerke der Bogendruckmaschine wird die Bogendruckmaschine derart betrieben, dass die Übertragungszylinder und die Formzylinder der Druckwerke in eine definierte Druckanstellung überführt werden, nämlich derart, dass dieselben ausschließlich über einen Schmitzringkontakt derselben aufeinander abrollen. Hierzu werden vorzugsweise von den Formzylindern Druckformen und/oder von den Übertragungszylindern Übertragungsformen entfernt. Das Abrollverhalten der Übertragungszylinder und der Formzylinder der Druckwerke ist demnach zur Ermittlung des Geometriefehlers unbeeinflusst von einem Kanaldurchgang der aufeinander abrollenden Zylinder. Farbauftragwalzen und gegebenenfalls Feuchtauftragwalzen werden von den Formzylindern abgestellt. Bei Geometriefehlern handelt es sich insbesondere um Rundlauffehler in einer Geberanbindung und/oder um kardanische Fehler in der Geberanbindung und/oder um Fehler in Folge einer Unrundheit von Schnitzringen und/oder um Fehler in Folge einer Unrundheit der Zylinderlager.In order to determine a geometry error of the printing units of the sheet-fed printing press, the sheet-fed press is operated in such a way that the transfer cylinders and the forme cylinders of the printing units are transferred to a defined pressure position, namely such that they roll over one another only via a bearer ring contact. For this purpose, transfer molds are preferably removed from the forme cylinders and / or from the transfer cylinders. The rolling behavior of the transfer cylinder and the forme cylinder of the printing units is therefore unaffected by a channel passage of the rolling cylinders rolling to determine the geometry error. Ink application rollers and optionally dampening rollers are turned off by the forme cylinders. Geometric errors are, in particular, concentricity errors in a sensor connection and / or cardanic errors in the encoder connection and / or errors as a result of out-of-roundness of carving rings and / or errors as a consequence of out-of-roundness of the cylinder bearings.
Weiterhin werden zur Ermittlung eines Geometriefehlers Reglerparameter der Antriebsregler der Direktantriebe derart eingestellt, dass über die Direktantriebe ein konstantes bzw. quasikonstantes Antriebsmoment in die Formzylinder der Druckwerke eingetrieben wird. Dabei werden Sollwerte und Istwerte der Antriebsregler der Direktantriebe und/oder Regelabweichungen zwischen den Sollwerten und den Istwerten der Antriebsregler der Direktantriebe erfasst, wobei die Regelabweichungen dem Geometriefehler der Druckwerke der Bogendruckmaschine entsprechen.Furthermore, controller parameters of the drive controllers of the direct drives are set such that a constant or quasi-constant drive torque is driven into the forme cylinders of the printing units via the direct drives in order to determine a geometry error. Setpoint values and actual values of the direct drive drives and / or control deviations between the setpoint values and the actual values of the direct drive drives are recorded, with the system deviations corresponding to the geometry error of the printing units of the sheet-fed press.
Bei der Ermittlung der Geometriefehler werden zur Bereitstellung des konstanten bzw. des quasikonstanten Antriebsmoments der Direktantriebe als Reglerparameter der Antriebsregler der Direktantriebe ein relativ kleiner Proportional-Verstärkungsfaktor für den Proportionalanteil des Antriebsreglers und eine relativ große Integral-Verzögerungszeit für den Integralanteil des Antriebsreglers eingestellt.When determining the geometry errors, a relatively small proportional gain factor for the proportional component of the drive controller and a relatively large integral delay time for the integral component of the drive controller are set as controller parameters of the direct drive controllers to provide the constant or quasi-constant drive torque of the direct drives.
Der hierbei eingestellte Proportional-Verstärkungsfaktor ist zumindest um den Faktor 10, insbesondere zumindest um den Faktor 20, kleiner als ein im Fortdruckbetriebe eingestellter Proportional-Verstärkungsfaktor. Bevorzugt ist der bei Ermittlung des Geometriefehlers eingestellte Proportional-Verstärkungsfaktor zumindest um den Faktor 40 kleiner als ein im Fortdruckbetrieb eingestellter Proportional-Verstärkungsfaktor.The proportional gain set here is at least by a factor of 10, in particular at least by a factor of 20, smaller than a proportional gain set in the printing operation. The proportional amplification factor set when determining the geometry error is preferably at least 40 times smaller than a proportional amplification factor set in the continuous printing mode.
Die bei Ermittlung des Geometriefehlers eingestellte Integral-Verzögerungszeit ist zumindest um den Faktor 10, insbesondere um den Faktor 20, größer als eine im Fortdruckbetrieb eingestellte Integral-Verzögerungszeit. Bevorzugt ist die zur Ermittlung des Geometriefehlers eingestellte Integral-Verzögerungszeit zumindest um den Faktor 60 größer als die im Fortdruckbetrieb eingestellte Integral-Verzögerungszeit. Die Integral-Verzögerungszeit wird zur Ermittlung des Geometriefehlers derart eingestellt, dass das Verhältnis aus der Integral-Verzögerungszeit zu einer Umlaufzeit des Formzylinders größer als 1 ist.The integral delay time set when determining the geometry error is at least a factor of 10, in particular by a factor of 20, greater than an integral delay time set in the continuous mode. The integral delay time set for determining the geometry error is preferably greater by at least a factor of 60 than the integral delay time set in the continuous printing mode. The integral delay time is set to determine the geometric error such that the ratio of the integral delay time to a cycle time of the forme cylinder is greater than one.
Die auf die obige Art und Weise ermittelten Geometriefehler der Druckwerke werden im Fortdruckbetrieb vorzugsweise als Korrekturwert-Werte bei der Antriebsregelung verwendet. Hierdurch kann im Fortdruckbetrieb die Antriebsregelung der eigenmotorisch angetriebenen Formzylinder verbessert werden.The geometrical errors of the printing units determined in the above manner are preferably used in the continuous printing operation as correction value values in the drive control. As a result, in drive mode, the drive control of the self-propelled forme cylinder can be improved.
