Description
Die vorliegende Erfindung betrifft ein Verfahren zum Ansteuern eines Digitaldruckwerks sowie eine Digitaldruckmaschine nach den Oberbegriffen der unabhängigen Patentansprüche.The present invention relates to a method for driving a digital printing unit and a digital printing machine according to the preambles of the independent claims.
In der Drucktechnik werden hauptsächlich sogenannte analoge Druckwerke eingesetzt, bei denen das Druckbild als komplette Vorlage, beispielsweise in Form einer Druckplatte oder eines Klischees, vorliegt. Daneben werden jedoch in jüngster Zeit vermehrt sogenannte digitale Druckwerke eingesetzt, bei denen das Druckbild in einer Recheneinheit erzeugt und anschließend, beispielsweise im Tintenstrahldruckverfahren oder im elektrofotografischen Druckverfahren, auf das Material oder einen Bildübertragungszylinder aufgebracht wird. Bei digitalen Druckverfahren besteht insbesondere die Schwierigkeit, den Beginn und das innere Raster, beispielsweise Druckzeilen, des Druckbildes mit dem Bahntransport zu synchronisieren, um eine Registerhaltigkeit zu gewährleisten.In printing technology mainly so-called analog printing units are used in which the printed image as a complete template, for example in the form of a printing plate or a cliché, is present. In addition, however, more and more recently so-called digital printing units are used in which the printed image is generated in a computing unit and then applied to the material or an image transfer cylinder, for example in the inkjet printing process or electrophotographic printing process. In digital printing processes, in particular, there is the difficulty of synchronizing the beginning and the inner screen, for example printed lines, of the printed image with the web transport in order to ensure register registration.
Im Stand der Technik werden dazu reale Inkrementalgeber oder Inkrementalgebernachbildungen verwendet. Üblicherweise wird dabei eine Geberauflösung gewählt, die auf einfache Weise in die druckwerksinterne Bearbeitung umgerechnet werden kann. Wird ein Druckwerk beispielsweise mit 600 dpi (Dots per Inch) betrieben, ist es zweckmäßig, wenn der Geber bzw. die Geberemulation ein Vielfaches oder, wie üblicherweise ausgebildet, ein Teiler von 600 ist. D. h. pro Inch Vorschubgeschwindigkeit der Warenbahn oder des Materialbogens wird eine entsprechende Anzahl an Inkrementen am Gebereingang des Digitaldruckwerks erwartet. Im Falle von 600 dpi kann beispielsweise eine Geberauflösung von 15 Inkrementen pro Inch gewählt werden. In einer typischen Geberauswertung innerhalb eines Druckwerks kann dies dann mit einer sogenannten Vierfach-Auswertung auf 60 Inkremente pro Inch gesteigert werden. Eine Erhöhung auf 600 Inkremente pro Inch wird dann typischerweise mittels einer Phasenregelschleife (PLL) durchgeführt.The prior art uses real incremental encoders or incremental encoder replicas for this purpose. Usually one will Encoder resolution selected, which can be easily converted into the internal processing. If a printing unit is operated, for example, at 600 dpi (dots per inch), it is expedient for the encoder or the encoder emulation to be a multiple or, as is usually the case, a divisor of 600. Ie. per inch feed rate of the web or the material sheet, a corresponding number of increments at the encoder input of the digital printing unit is expected. In the case of 600 dpi, for example, a sensor resolution of 15 increments per inch can be selected. In a typical encoder evaluation within a printing unit, this can then be increased to 60 increments per inch with a so-called quadruple evaluation. An increase to 600 increments per inch is then typically performed by means of a Phase Locked Loop (PLL).

Diese Lösung weist jedoch eine Anzahl von Nachteilen auf. Zunächst ist festzustellen, dass sowohl die Position des Druckbildes auf dem Bedruckstoff als auch die innere, gerasterte Zusammensetzung des Druckbildes von der Geberauflösung abhängt. Zusätzlich ist die Auswertung des Gebereingangs jitterbehaftet, da diese oftmals zeitdiskret durchgeführt wird. Die Auswertung des Gebereingangs ist darüber hinaus rauschbehaftet. Filterungen zur Verbesserung des Gebersignals führen zu Totzeiten bzw. Verzögerungen im Gesamtsystem. Auch ist es nicht immer möglich, einen Geber bzw. eine Geberemulation mit einer für das Druckwerk passenden Auflösung bereitzustellen. In diesem Fall verschlechtert sich die Genauigkeit weiter. Auch mechanische Störungen im Bahntransport im Falle eines realen Gebers oder Fehler in einer Geberankopplung führen zu Fehlern im Druckbild. Schließlich ist eine realer Inkrementalgeber bzw. eine Geberemulation zusammen mit der im Druckwerk notwendigen Geberauswertung kostenintensiv.However, this solution has a number of disadvantages. First, it should be noted that both the position of the printed image on the substrate and the inner, screened composition of the printed image depends on the encoder resolution. In addition, the evaluation of the encoder input is jittery, since this is often performed time-discrete. The evaluation of the encoder input is also noisy. Filtering to improve the encoder signal lead to dead times or delays in the overall system. Also, it is not always possible to provide a transmitter or a Geberemulation with a resolution suitable for the printing unit. In this case, the accuracy deteriorates further. Even mechanical disturbances in rail transport in the case of a real encoder or errors in a encoder connection lead to errors in the printed image. Finally, a real incremental encoder or encoder emulation together with the encoder evaluation necessary in the printing unit is cost-intensive.
Die
Es ist daher wünschenswert, ein Digitaldruckwerk genauer und insbesondere auch einfacher an den Transport der Warenbahn bzw. des Materialbogens anzukoppeln.It is therefore desirable to couple a digital printing unit more precisely and in particular also easier to the transport of the material web or of the material sheet.
Erfindungsgemäß werden ein Verfahren zum Ansteuern eines digitalen Druckwerks sowie eine Digitaldruckmaschine mit den Merkmalen der unabhängigen Patentansprüche vorgeschlagen. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche sowie der nachfolgenden Beschreibung.According to the invention, a method for driving a digital printing unit and a digital printing machine with the features of the independent claims are proposed. Advantageous embodiments are the subject of the dependent claims and the following description.
Die Erfindung fußt im Wesentlichen auf der Erkenntnis, dass eine genauere und dennoch einfachere Ankopplung eines digitalen Druckwerks an den Bahntransport bereitgestellt werden kann, wenn eine - zweckmäßigerweise wellenlose - Transporteinrichtung verwendet wird und das Druckwerk direkt an die Bewegungssteuerungseinrichtung (Motion Control, SPS), insbesondere über eine Echtzeit-Busankopplung, angebunden wird. Eine herkömmliche, mittelbare und daher nur ungenaue Ankopplung über Inkrementalgebersignale wird vermieden. Der Druckvorgang, d.h. die Bebilderung des Zylinders bei einem elektrofotographischen Verfahren bzw. Aufbringen von Farbe bei einem Tintenstrahlverfahren, wird direkt mittels der digital übertragenen Werte gesteuert.The invention is based essentially on the recognition that a more accurate and yet simpler coupling of a digital printing unit to the web transport can be provided if a - expediently shaftless - transport device is used and the printing unit directly to the motion control device (Motion Control, PLC), in particular via a real-time bus connection. A conventional, indirect and therefore only inaccurate coupling via incremental encoder signals is avoided. The printing process, i. the imaging of the cylinder in an electrophotographic process in an ink-jet process is directly controlled by the digitally transmitted values.
Zweckmäßigerweise wird das Digitaldruckwerk direkt an die Motion Control und/oder die Antriebe und/oder das Kommunikationssystem (z.B. Feldbus) angeschlossen. Direkter Anschluss bedeutet dabei, dass keine (binären) Inkrementalgeberinformationen vom Bewegungssteuerungssystem an das Digitaldruckwerk übertragen werden, sondern Zahlenwerte und optional auch weitere (Binär-)Informationen. Diese Zahlenwerte können beispielsweise eine Maschinengeschwindigkeit, eine Leitachsposition, eine Beschleunigung, ein Ruck usw. sein. Die weiteren Informationen können z.B. zur Übertragung von Statusinformationen dienen (Beschleunigungsvorgänge signalisieren, Steuerung der Bebilderung aus der SPS, usw.).Conveniently, the digital printing unit is connected directly to the motion control and / or the drives and / or the communication system (eg fieldbus). In this case, direct connection means that no (binary) incremental encoder information is transmitted from the motion control system to the digital printing unit, but numerical values and optionally also further (binary) information. These numerical values can be, for example, a machine speed, a master axis position, a Acceleration, a jerk, etc. The further information can be used, for example, to transmit status information (signal acceleration processes, control the imaging from the PLC, etc.).
Vorteilhaft hieran ist, dass die Auflösung der übertragenen Informationen wesentlich höher gewählt werden kann, als dies bei Geberauswertung der Fall ist. Die übertragenen Informationen sind nicht jitter- oder rauschbehaftet, sondern digital genau.An advantage of this is that the resolution of the transmitted information can be chosen much higher than is the case with encoder evaluation. The transmitted information is not jittery or noisy, but digitally accurate.
In der digitalen Drucktechnik gilt - ganz im Gegensatz zur herkömmlichen analogen Drucktechnik - das Prinzip, dass die Formatlänge nicht mit der Leitachsbewegung zusammenhängt. Ein digitales Druckwerk wird üblicherweise lediglich im Abstand des Druckrasters, bspw. einer Druckzeile, mit Impulsen versorgt, um den Druckzeitpunkt des nächsten Rasterelements zu kennzeichnen. Aus diesem Grund besteht in der digitalen Drucktechnik auch seit langem die gefestigte Übung, Druckwerke impulsbehaftet anzubinden. Die Erfindung wendet sich nun bewusst von dieser Tradition ab. Durch eine direkte, digitale Anbindung können deutlich genauere Positionsdaten von dem Druckwerk empfangen werden, welches dann intern basierend auf diesen Positionsdaten die Druckzeitpunkte für die Rasterelemente bestimmt.In digital printing technology, in contrast to conventional analogue printing technology, the principle is that the format length is not related to the leading axis movement. A digital printing unit is usually provided with pulses only at a distance from the print screen, for example a print line, in order to mark the printing time of the next screen element. For this reason, in digital printing technology, there has been a long-established practice of binding printing units with impulses. The invention now consciously turns away from this tradition. By means of a direct, digital connection, significantly more precise position data can be received by the printing unit, which then internally determines the printing times for the raster elements based on these position data.
Eine zyklische Übertragung bietet den Vorteil genauer Extrapolationen und Interpolationen. Anhand der Übertragung von Positionsdaten zu bekannten und damit vorbestimmbaren, insbesondere äquidistanten, Zeitpunkten kann das die Positionsdaten empfangende Druckwerk bzw. dessen Steuergerät ein Druckbild mit geringem Versatz ausgeben. Bei Echtzeitkommunikationssystemen wird Information typischerweise in sog. Kommunikationszyklen übertragen. Meist ist bekannt, zu welchem Zeitpunkt (innerhalb des Kommunikationszyklus) die übertragenen Daten gültig sind (im selben Zyklus), gültig waren (in vorangegangenen Zyklen) oder gültig sein werden (in folgenden Zyklen). Hierdurch können im Digitaldruckwerk hochgenaue Interpolationen durchgeführt werden. Durch die Kenntnis der hochgenauen Zykluszeit des Kommunikationszyklus bzw. Istwertverarbeitungszeitpunkte innerhalb des Kommunikationszyklus kann im Digitaldruckwerk auch eine bessere Datenverarbeitung, z.B. durch eine PLL, zur Bebilderung (z.B. Druckkopfansteuerung) erreicht werden. Ein weiterer Vorteil von Echtzeitkommunikationssystemen mit zyklischer Übertragung ist die nahezu jitterfreie Taktung der (hochsetzenden) PLL mittels der Information der Übertragungszyklen (z.B. Synchronisationsinformation des Echtzeitkommunikationsystems SERCOS III).Cyclic transmission offers the advantage of accurate extrapolations and interpolations. On the basis of the transmission of position data to known and thus predeterminable, in particular equidistant, times, the printing unit receiving the position data or its control unit can output a printed image with a small offset. In real-time communication systems, information is typically transmitted in so-called communication cycles. It is usually known at what time (within the communication cycle) the transmitted data will be valid (in the same cycle), valid (in previous cycles) or will be valid (in subsequent cycles). As a result, highly accurate interpolations can be performed in the digital printing unit. By knowing the highly accurate cycle time of the Communication cycle or actual value processing times within the communication cycle in the digital printing unit also better data processing, eg by a PLL, for imaging (eg printhead control) can be achieved. Another advantage of cyclic-transmission real-time communication systems is the almost jitter-free clocking of the (up-setting) PLL by means of the information of the transmission cycles (eg synchronization information of the SERCOS III real-time communication system).
Die direkte Anbindung bietet zusätzlich vorteilhaft die Möglichkeit einer diagnostischen Anbindung. Auch kann das digitale Druckwerk von der Bewegungssteuerungseinrichtung gesteuert werden, so dass die bisher bestehende Notwendigkeit einer überlagerten Steuerungseinrichtung entfällt.The direct connection additionally offers the possibility of a diagnostic connection. Also, the digital printing unit can be controlled by the motion control device, so that the previously existing need for a higher-level control device is eliminated.
