Description

Die Erfindung betrifft eine Verarbeitungsmaschine, insbesondere eine Bogenmaterial verarbeitende Druckmaschine bzw. Lackiermaschine, nach dem Oberbegriff des unabhängigen Anspruchs.The invention relates to a processing machine, in particular a sheet material processing printing machine or coating machine, according to the preamble of the independent claim.

Bogenmaterial verarbeitende Druckmaschinen sowie Lackiermaschinen verfügen über eine Vielzahl von Einrichtungen, die im Druck-/Lackierbetrieb, Einrichtbetrieb oder Wartungsbetrieb der jeweiligen Maschine angetrieben werden müssen. Bei klassischen Konstellationen werden alle anzutreibenden Einrichtungen einer derartigen Druck- bzw. Lackiermaschine von einem sogenannten Hauptantrieb angetrieben. Alle anzutreibenden Einrichtungen sind dann üblicherweise mechanisch über eine getriebetechnische Kopplung, insbesondere einen geschlossenen Räderzug, mit dem Hauptantrieb verbunden.Sheet-fed printing machines and painting machines have a variety of facilities that need to be driven in the printing / painting, setting or maintenance operation of the respective machine. In classical constellations all driven devices of such a printing or coating machine are driven by a so-called main drive. All driven devices are then usually mechanically connected via a transmission technology coupling, in particular a closed gear train, with the main drive.

Bei modernen Konzepten für Bogenmaterial verarbeitenden Druckmaschinen sind zumindest einige der anzutreibenden Einrichtungen einer Druckmaschine eigenmotorisch angetrieben. So ist es aus dem Stand der Technik bereits bekannt, Formzylinder bzw. Plattenzylinder von Druckwerken der Druckmaschine eigenmotorisch dadurch anzutreiben, dass jedem der Formzylinder ein separater Antrieb zugeordnet ist, so dass die Formzylinder unabhängig vom Hauptantrieb angetrieben werden können.In modern concepts for sheet material processing printing presses at least some of the driven devices of a printing press are driven by an engine. Thus, it is already known from the prior art to drive form cylinders or plate cylinders of printing units of the printing press by virtue of the fact that each of the form cylinder is assigned a separate drive, so that the form cylinder can be driven independently of the main drive.

Eine Bogenmaterial verarbeitende Druckmaschine, deren Druckwerke eigenmotorisch angetriebene Formzylinder (Plattenzylinder) aufweisen, ist aus der EP 0 834 398 B1 bekannt, wobei nach diesem Stand der Technik vom Hauptantrieb angetriebene Gummizylinder der Druckwerke und der jeweilige eigenmotorisch angetriebene Formzylinder (Plattenzylinder) jedes Druckwerks über jeweils eine schaltbare Kupplung koppelbar bzw. entkoppelbar sind.A sheet material processing printing machine whose printing works have self-propelled forme cylinder (plate cylinder), is from the EP 0 834 398 B1 known, which is driven by the main drive according to this prior art Blanket cylinders of the printing units and the respective self-propelled forme cylinder (plate cylinder) of each printing unit can be coupled or decoupled via a respective switchable coupling.

Um einen sicheren Betrieb einer Druckmaschine zu gewährleisten, müssen steuerungsseitig für alle Gefährdungen, die durch Antriebe der Druckmaschine verursacht werden, Schutzmaßnahmen implementiert werden. Dies gilt sowohl für den Hauptantrieb als auch für jeden unabhängig vom Hauptantrieb antreibbaren Antrieb einer eigenmotorisch angetriebenen Einrichtung. So ist üblicherweise nur dann ein sicherer Betrieb eines Antriebs zu gewährleisten, wenn für denselben grundlegende Schutzmaßnahmen bzw. Sicherheitsvorgaben implementiert sind, insbesondere Maßnahmen für ein sicheres Stillsetzen des Antriebs, Maßnahmen gegen ein unerwartetes Anlaufen des Antriebs, Maßnahmen zur Einhaltung maximaler Geschwindigkeiten des Antriebs, Maßnahmen zur Einhaltung maximaler Wege des Antriebs sowie Maßnahmen zur Einhaltung einer korrekten Drehrichtung desselben. Die Implementierung all dieser Schutzmaßnahmen für den Hauptantrieb sowie jeden vom Hauptantrieb unabhängig antreibbaren Antrieb der eigenmotorisch angetriebenen Einrichtungen der Druckmaschine erfordert steuerungsseitig einen hohen Aufwand. Dies ist insgesamt von Nachteil.In order to ensure safe operation of a printing machine, protective measures must be implemented on the control side for all hazards caused by drives of the printing press. This applies both to the main drive as well as each independently driven by the main drive drive a self-propelled device. Thus, a safe operation of a drive is usually only to be ensured if basic protective measures or safety specifications are implemented for it, in particular measures for a safe shutdown of the drive, measures against an unexpected start of the drive, measures to maintain maximum speeds of the drive, measures to comply with maximum distances of the drive and measures to maintain a correct direction of rotation of the same. The implementation of all these protective measures for the main drive and each independently driven from the main drive drive the self-propelled devices of the printing press requires a lot of effort on the control side. This is disadvantageous overall.

Aufgabe der Erfindung ist es, eine Verarbeitungsmaschine der eingangs genannten Art mit wenigstens einem Druck- und/oder Lackwerk umfassend je einen eine Druckform tragenden, mit einem Einzelantrieb gekoppelten Plattenzylinder bzw. Formzylinder, hinsichtlich der Betriebssicherheit zu verbessern.The object of the invention is to improve a processing machine of the type mentioned with at least one printing and / or coating unit each having a printing plate bearing, coupled with a single drive plate cylinder or forme cylinder, in terms of reliability.

Die Aufgabe wird durch die Ausbildungsmerkmale von Anspruch 1 gelöst.The object is solved by the training features of claim 1.

Die erfindungsgemäße Verarbeitungsmaschine weist eine Steuerungseinrichtung auf, die unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses einen Synchronbetrieb zwischen den von dem oder jedem Hauptantrieb und Räderzug angetriebenen Zylindern bzw. Walzen eines Druckwerks und dem jeweiligen eigenmotorisch angetriebenen, d.h. einzeln angetriebenen Platten-/Formzylinder vorgibt, nämlich dadurch, dass die Steuerungseinrichtung die oder jede schaltbare Kupplung reibschlüssig (kraftschlüssig) zwischen dem Gummituchzylinder oder dem zugeordneten Bogenführungszylinder (Druckzylinder) und dem Plattenzylinder des jeweiligen Druckwerks bzw. zwischen dem Formzylinder und dem Bogenführungszylinder (Druckzylinder) des jeweiligen Lackwerkes schließt und den Einzelantrieb des Plattenzylinders im Druckwerk bzw. den Einzelantrieb des Formzylinders im Lackwerk momentenlos schaltet. Dabei schließt die Angabe "Einzelantrieb des Formzylinders im Lackwerk" auch einen eigenmotorisch angetriebenen (Einzelantrieb) Antrieb eines Formzylinders in einem Flexodruckwerk ein. Ebenso schließt der Begriff "Druckform" eine Lackform bzw. eine Flexodruckform ein. Der Begriff der Betriebssicherheit schließt den Notbetrieb eines einzelmotorisch angetriebenen Plattenzylinders /Formzylinders bei Ausfall dessen Einzelantriebes sowie die Betriebssicherheit unterstützende Diagnosemöglichkeiten ein.The processing machine according to the invention has a control device auf, which specifies directly in the presence of a safety-related event synchronous operation between the driven by the or each main drive and gear train cylinders or rollers of a printing unit and the respective self-propelled, ie individually driven plate / forme cylinder, namely the fact that the control device or each switchable clutch frictionally (positively) between the blanket cylinder or the associated sheet guiding cylinder (impression cylinder) and the plate cylinder of the respective printing unit or between the forme cylinder and the sheet guiding cylinder (impression cylinder) of the respective coating unit closes and the single drive of the plate cylinder in the printing unit or the single drive of Form cylinder in the coating unit torquelessly switched. The term "single drive of the forme cylinder in the coating unit" also includes an own motor driven (single drive) drive of a forme cylinder in a flexographic printing unit. Likewise, the term "printing form" includes a paint form or a flexographic printing form. The term of operational safety includes the emergency operation of a single-motor driven plate cylinder / forme cylinder in case of failure of the individual drive and the reliability supporting diagnostic options.

Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, dass eine Steuerungseinrichtung unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses einen Synchronbetrieb zwischen den vom Hauptantrieb und Räderzug angetriebenen Einrichtungen der Verarbeitungsmaschine und dem eigenmotorisch angetriebenen Platten- bzw. Formzylinder erzwingt. Der Synchronbetrieb wird dadurch erzwungen, dass die Steuerungseinrichtung die Schaltkupplung, die im Druck-/ Lackierbetrieb der Verarbeitungsmaschine geöffnet ist und den Platten- bzw. Formzylinder vom Hauptantrieb und Räderzug entkoppelt, schließt und den Einzelantrieb des Platten- bzw. Formzylinders momentenlos schaltet. Hierdurch wird erzielt, dass alle Schutzmaßnahmen bzw. Sicherheitsvorgaben des Hauptantriebs mit Räderzug auf den Antrieb des jeweiligen eigenmotorisch angetriebenen Platten-/Formzylinders steuerungsseitig übertragen werden.
Mit dieser Betriebsweise kann ein unkontrolliertes Drehen (Austrudeln) eines Zylinders nach Ausfall des Antriebsmomentes des dem Zylinder zugeordneten Einzelantriebes unterbunden werden. Ein weiterer Vorteil besteht darin, dass der Produktionsprozess (Druck- und/oder Lackierbetrieb) nach Ausfall eines Einzelantriebes nicht unterbrochen werden muss. Damit sind Notlaufeigenschaften an dem ausgefallenen, ansonsten eigenmotorisch angetriebenen Zylinder gewährleistet. Ist die Einsatzfähigkeit des ausgefallenen Einzelantriebes wieder hergestellt, so kann die Schaltkupplung (über die Steuereinrichtung) geöffnet und der bisher antriebslose (Einzelantrieb momentenlos) Zylinder mittels des Einzelantriebes eigenmotorisch wieder angetrieben werden.For the purposes of the present invention, it is proposed that a control device force a synchronous operation between the devices of the processing machine driven by the main drive and the gear train and the plate or forme cylinder driven by the motor directly in the presence of a safety-relevant event. The synchronous operation is enforced by the fact that the control device closes the clutch, which is open in the printing / painting operation of the processing machine and the plate or forme cylinder from the main drive and gear train, and switches the single drive of the plate or forme cylinder torqueless. This ensures that all protective measures or safety requirements of the main drive with gear train are transmitted to the drive of the respective self-propelled plate / plate cylinder control side.
With this mode of operation can uncontrolled turning (tumbling) of a cylinder be suppressed after failure of the drive torque of the cylinder associated with individual drive. Another advantage is that the production process (printing and / or painting) after failure of a single drive must not be interrupted. This emergency running properties are guaranteed on the failed, otherwise self-propelled cylinder. If the operational capability of the failed individual drive is restored, then the clutch can be opened (via the control device) and the previously unpowered (individual torque-less) cylinder can be driven by the individual drive by means of an individual motor.

Ein weiterer Vorteil besteht darin, dass bei einer möglichen Überlastung des Einzelantriebes die Steuereinrichtung die Schaltkupplung zwischen einem der von Hauptantrieb und Räderzug angetriebenen Zylinder und dem Platten- bzw. Formzylinder unter Kraftschluss schließt und danach den Einzelantrieb des Platten- bzw. Formzylinders momentenlos schaltet. Somit kann der jeweilige Platten- bzw. Formzylinder ohne Beeinträchtigung des Momentes in den Hauptantrieb gekuppelt werden. Die in diesem Fall nicht mehr realisierbare Registerung der betroffenen Zylinderachse kann über die Registerkorrektureinrichtungen anderer Zylinderachse ausgeglichen werden.Another advantage is that with a possible overload of the individual drive, the control device closes the clutch between one of the driven by the main drive and gear train cylinder and the plate or forme cylinder under adhesion and then switches the single drive of the plate or forme cylinder torqueless. Thus, the respective plate or forme cylinder can be coupled without affecting the moment in the main drive. The registration of the cylinder axis concerned which can no longer be realized in this case can be compensated for via the register correction devices of other cylinder axes.

Von Vorteil ist ebenso, dass - beispielsweise zu Diagnosezwecken - der Antrieb von Platten- bzw. Formzylinder wahlweise über den Hauptantrieb und Räderzug oder über den jeweiligen Einzelantrieb erfolgen kann. Hierzu wird mittels der Maschinensteuerung die Schaltkupplung wahlweise geöffnet oder geschlossen. Beispielsweise können durch den wahlweisen Antrieb mögliche Qualitätsabweichungen im Verarbeitungsprozess festgestellt, Veränderungen analysiert und dem jeweiligen Antriebskonzept zugewiesen und abgestellt werden.Another advantage is that - for diagnostic purposes, for example - drive of plate or form cylinder can be done either via the main drive and gear train or via the respective single drive. For this purpose, the clutch is selectively opened or closed by means of the machine control. For example, by the optional drive possible quality deviations can be detected in the processing process, changes analyzed and assigned to the respective drive concept and turned off.

Die Bogenrotationsdruckmaschine ist beispielsweise mit einem Anleger 4, fünf Offsetdruckwerken 1, einem Lackwerk 2 sowie einem Ausleger 5 dargestellt. Jedes Offsetdruckwerk 1 weist in bekannter Weise ein Farbwerk 12 mit Farbwerkwalzen, einen eine Druckform tragenden Zylinder 10, hier als Plattenzylinder 10, und einen Gummituchzylinder 8 auf. Bei Bedarf ist jedem Plattenzylinder 10 ein Feuchtwerk zugeordnet.
Das Lackwerk 2 weist in bekannter Weise eine Dosiereinrichtung 11 für das zu verarbeitende Medium (Lack, Farbe), bevorzugt ein Kammerrakel mit zugeordneter, gerasterter Auftragwalze, sowie einen eine Druckform (Lackform, Flexodruckform) tragenden Zylinder 9, hier als Formzylinder 9, auf.The sheet-fed rotary printing machine is shown for example with a feeder 4, five offset printing units 1, a coating unit 2 and a boom 5. Each offset printing unit 1 has in a known manner an inking unit 12 with inking rollers, a cylinder 10 carrying a printing plate, here as a plate cylinder 10, and a blanket cylinder 8. If necessary, each plate cylinder 10 is associated with a dampening unit.
The coating unit 2 has in a known manner a metering device 11 for the medium to be processed (paint, ink), preferably a chambered doctor blade with assigned, screened applicator roll, as well as a printing plate (paint form, flexographic printing) carrying cylinder 9, here as a forme cylinder 9, on.

Plattenzylinder 10 und Formzylinder 9 tragen jeweils zumindest eine Druckform und sind mit den Farbauftragwalzen des Farbwerkes 12 bzw. der Auftragwalze der Dosiereinrichtung 11 in Kontakt. Für den Bogentransport in Förderrichtung 3 sind mehrere Bogenführungszylinder 6 vorgesehen. In jedem Offsetdruck- bzw. Lackwerk 1, 2 ist ein als Druckzylinder ausgebildeter Bogenführungszylinder 6 mit dem jeweiligen Gummituchzylinder 8 bzw. Formzylinder 9 in Funktionsverbindung, wobei im ersten Offsetdruckwerk 1 dem als Druckzylinder ausgebildeten Bogenführungszylinder 6 eine Anlagetrommel als Bogenführungszylinder 6 vorgeordnet ist. Für den Bogentransport sind zwischen den als Druckzylinder ausgebildeten Bogenführungszylindern 6 der Druck- bzw. Lackwerke 1, 2 weitere Bogenführungszylinder 6 als Transferzylinder angeordnet. Den als Druckzylinder ausgebildeten Bogenführungszylindern 6 sowie den Gummituchzylindern 8 und dem Formzylinder 9 sind bevorzugt Waschvorrichtungen 7 zugeordnet.
Zumindest sämtliche Bogenführungszylinder 6 sind über einen nicht näher aufgezeigten Hauptantrieb (zumindest ein einspeisender Antriebsmotor) und einen geschlossenen Räderzug antriebsseitig miteinander gekoppelt. In diesen Räderzug sind ebenfalls die Gummituchzylinder 8 der Offsetdruckwerke 1 mit je einem Gummituchzylinder-Zahnrad 13 integriert. Bei den Lackwerken 2 ist der dem Formzylinder 9 benachbarte Bogenführungszylinder 6 mit je einem Bogenführungszylinder-Zahnrad 17 in diesen Räderzug integriert.Plate cylinder 10 and forme cylinder 9 each carry at least one printing plate and are in contact with the inking rollers of the inking unit 12 or the applicator roller of the metering device 11. For the sheet transport in the conveying direction 3 more sheet guiding cylinder 6 are provided. In each offset printing or coating unit 1, 2 is designed as a printing cylinder sheet guiding cylinder 6 with the respective blanket cylinder 8 and form cylinder 9 in functional connection, wherein in the first offset printing unit 1 formed as a printing cylinder sheet guiding cylinder 6 a collision drum is arranged as a sheet guiding cylinder 6. For the sheet transport between the printing cylinder 2 designed as a pressure cylinder sheet of the printing or coating units 1, 2 more sheet guiding cylinder 6 are arranged as a transfer cylinder. Designed as a pressure cylinder sheet guiding cylinders 6 and the blanket cylinders 8 and the forme cylinder 9 washing devices 7 are preferably assigned.
At least all of the sheet guiding cylinders 6 are coupled to each other via an unspecified main drive (at least one feeding drive motor) and a closed gear train on the drive side. In this gear train also the blanket cylinder 8 of the offset printing units 1, each with a blanket cylinder gear 13 are integrated. In the coating units 2 of the forme cylinder 9 adjacent sheet guiding cylinder 6, each with a sheet guiding cylinder gear 17 is integrated into this gear train.

Bevorzugt ist jeder Plattenzylinder 10 und jeder Formzylinder 9 - von Hauptantrieb und Räderzug mechanisch entkoppelt - durch je einen Einzelantrieb M (auch Direktantrieb genannt), d.h. einen separaten Antriebsmotor, antreibbar. Diese Einzelantriebe M sind mit einer Maschinensteuerung gekoppelt und werden in vorgebbarer Weise gegenüber dem Hauptantrieb und Räderzug mit den Bogenführungszylindern 6 bei den Lackwerken 2 sowie den zusätzlich mit Hauptantrieb und Räderzug gekoppelten Gummituchzylindern 8 bei den Offsetdruckwerken 1 einzeln angetrieben. Beim Formzylinder 9 und Plattenzylinder 10 handelt es sich demnach um eine mittels Einzelantrieb M eigenmotorisch angetriebene Einrichtung der Bogenrotationsdruckmaschine.
An dieser Stelle sei darauf hingewiesen, dass die Bogenrotationsdruckmaschine mehrere Hauptantriebe umfassen kann, die in den geschlossenen Räderzug einspeisen. Bei den Offsetdruckwerken 1 wird jeder mit dem benachbarten Bogenführungszylinder 6 antriebsseitig gekoppelte Gummituchzylinder 8 vom Hauptantrieb mit Räderzug angetrieben und in den Offsetdruckwerken 1 wird bevorzugt jeder Plattenzylinder 10 eigenmotorisch mittels Einzelantrieb M angetrieben. Der dem Formzylinder 9 im Lackwerk 2 benachbarte Bogenführungszylinder 6 wird vom Hauptantrieb mit Räderzug angetrieben und bevorzugt jeder der Formzylinder 9 der Lackwerke 2 wird eigenmotorisch mittels Einzelantrieb M angetrieben. Erfindungsgemäß kann eine Bogenrotationsdruckmaschine mit mehreren Offsetdruckwerken 1 bzw. Lackwerken 2 auch einzelne Offsetdruckwerke 1 und/oder Lackwerke 2 aufweisen, deren Platten- bzw. Formzylinder 10, 9 keinen Einzelantrieb M aufweisen. Derartige konventionelle Werke 1, 2 werden insgesamt mittels Hauptantrieb und Räderzug innerhalb der Verarbeitungsmaschine angetrieben. Die entsprechenden Platten- bzw. Formzylinder 10, 9 sind somit in den Räderzug integriert.Preferably, each plate cylinder 10 and each form cylinder 9 - mechanically decoupled from the main drive and gear train - each by a single drive M (also called direct drive), ie a separate drive motor, driven. These individual drives M are coupled to a machine control and are driven in a predeterminable manner with respect to the main drive and gear train with the sheet guiding cylinders 6 in the coating units 2 and additionally coupled with main drive and gear train blanket cylinders 8 at the offset printing units 1 individually. When form cylinder 9 and plate cylinder 10 is therefore a self-powered by means of individual drive M device of the sheet-fed rotary printing press.
It should be noted at this point that the sheet-fed rotary printing press may comprise a plurality of main drives which feed into the closed gear train. In the offset printing 1 each with the adjacent sheet guiding cylinder 6 drive side coupled blanket cylinder 8 is driven by the main drive with gear train and in the offset printing units 1, preferably each plate cylinder 10 is driven by motor M by means of individual drive. The form cylinder 9 in the coating unit 2 adjacent sheet guiding cylinder 6 is driven by the main drive with gear train and preferably each of the forme cylinder 9 of the coating units 2 is driven by an individual motor M self-propelled. According to the invention, a sheet-fed rotary printing press with a plurality of offset printing units 1 or coating units 2 can also be individual offset printing units 1 and / or coating units 2, the plate or forme cylinder 10, 9 have no single drive M. Such conventional plants 1, 2 are driven in total by means of the main drive and gear train within the processing machine. The corresponding plate or forme cylinder 10, 9 are thus integrated into the gear train.

Bei Druckwerken 1 ist die Schaltkupplung 15 zwischen den von Hauptantrieb und Räderzug angetriebenen Zylindern und dem jeweiligen mittels Einzelantrieb eigenmotorisch angetriebenen Plattenzylinder 10 angeordnet.
Wie in Fig. 2 gezeigt, ist zwischen dem Gummituchzylinder 8 und dem Plattenzylinder 10 eines Offsetdruckwerkes 1 eine kraftschlüssig wirkende Schaltkupplung 15 angeordnet. Alternativ ist die Schaltkupplung 15 auch zwischen einem Bogenführungszylinder 6 und dem Plattenzylinder 10 anordenbar.In printing units 1, the clutch 15 is disposed between the driven by the main drive and gear train cylinders and the respective by means of individual drive motor driven plate cylinder 10.
As in Fig. 2 is shown, a force-locking clutch 15 is disposed between the blanket cylinder 8 and the plate cylinder 10 of an offset printing unit 1. Alternatively, the clutch 15 can also be arranged between a sheet guiding cylinder 6 and the plate cylinder 10.

Im vorliegenden Beispiel ist die Schaltkupplung 15 am Plattenzylinder 10 angeordnet und am Plattenzylinder 10 ist ferner ein frei drehbares Zahnrad 14 der Schaltkupplung 15 benachbart angeordnet. Das frei drehbare Zahnrad 14 ist mit dem Gummituchzylinder-Zahnrad 13 des vom Hauptantrieb angetriebenen Räderzuges im ständigen Eingriff. Von Hauptantrieb und Räderzug wird somit auf das Gummituchzylinder-Zahnrad 13 ein Eintrieb 16 (vom Hauptantrieb mit Räderzug) eingespeist.
In einer weiteren Ausbildung kann das frei drehbare Zahnrad 14 mittels einer getriebetechnischen Verbindung direkt oder mittels einer weiteren Kupplung mit dem nachgeordneten Farbwerk 12 antriebsseitig gekoppelt sein.In the present example, the clutch 15 is disposed on the plate cylinder 10 and the plate cylinder 10, a freely rotatable gear 14 of the clutch 15 is further arranged adjacent. The freely rotatable gear 14 is in constant mesh with the blanket cylinder gear 13 of the gear train driven by the main drive. Of the main drive and gear train is thus fed to the blanket cylinder gear 13 a drive 16 (from the main drive with gear train).
In a further embodiment, the freely rotatable gear 14 may be coupled by means of a transmission connection directly or by means of another coupling with the downstream inking unit 12 on the drive side.

Im Normaldruckbetrieb, in welchem der Plattenzylinder 10 eigenmotorisch vom Einzelantrieb M angetrieben wird, ist die Schaltkupplung 15 geöffnet, um so den Plattenzylinder 10, speziell das Zahnrad 14, vom Hauptantrieb bzw. vom Gummituchzylinder-Zahnrad 13 zu entkoppeln.In normal pressure operation, in which the plate cylinder 10 is driven by an individual motor M, the clutch 15 is opened, so as to decouple the plate cylinder 10, especially the gear 14, from the main drive or from the blanket cylinder gear 13.

Zur Implementierung der notwendigen Sicherheitsmaßnahmen für den eigenmotorisch angetriebenen Plattenzylinder 10 wird im Sinne der hier vorliegenden Erfindung vorgeschlagen, die Sicherheitsmaßnahmen des Hauptantriebs (mit Räderzug) steuerungsseitig auf den eigenmotorisch angetriebenen Plattenzylinder 10 des jeweiligen Offsetdruckwerks 1 dadurch zu vererben, dass bei Vorliegen eines sicherheitsrelevanten Ereignisses ein Synchronbetrieb zwischen dem vom Hauptantrieb und Räderzug angetriebenen Zylinder, insbesondere der Bogenführungszylinder 6 (Druckzylinder) oder Gummituchzylinder 8 und dem vom Einzelantrieb M eigenmotorisch antreibbaren Plattenzylinder 10 vorgegeben wird. Im vorliegenden Beispiel wird dies über ein Gummituchzylinder-Zahnrad 13 realisiert.To implement the necessary safety measures for the self-propelled plate cylinder 10 is proposed in the sense of the present invention, the safety measures of the main drive (with gear train) on the control side on the self-propelled plate cylinder 10 of the respective offset printing unit 1 thereby inherit that in the presence of a security-related event a Synchronous operation between the cylinder driven by the main drive and gear train cylinder, in particular the sheet guiding cylinder 6 (impression cylinder) or blanket cylinder 8 and the self-propelled by the individual drive M plate cylinder 10 is specified. In the present example, this is realized via a blanket cylinder gear 13.

Hierzu dient im Sinne der vorliegenden Erfindung eine Steuerungseinrichtung 18, der als Eingangssignal ein Signal zugeführt wird, welches Daten darüber enthält, ob ein sicherheitsrelevantes Ereignis vorliegt oder nicht. Die Steuerungseinrichtung 18 ist bzw. mehrere Steuereinrichtungen 18 sind bevorzugt mit einem Leitstand gekoppelt. Eine derartige Steuereinrichtung 18 gibt unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses einen Synchronbetrieb zwischen dem vom Hauptantrieb angetriebenen Gummituchzylinder-Zahnrad 13 und dem vom Einzelantrieb M angetriebenen Plattenzylinder 10 dadurch vor, dass die Steuerungseinrichtung 18 über ein Ausgangssignal die Schaltkupplung 15 zum frei drehbaren Zahnrad 14 unter Kraftschluss schließt. In dieser ersten Schaltstellung ist die Schaltkupplung 15 mit dem Zahnrad 14 und über das Zahnrad 14 mit dem Gummtuchzylinder-Zahnrad 13 gekoppelt. Über ein weiteres Ausgangssignal der Steuereinrichtung 18 wird der Einzelantrieb M des Plattenzylinders 10 momentenlos geschaltet, indem dieser z. B. stromlos bzw. energielos geschaltet wird. Durch das Schließen der kraftschlüssigen Schaltkupplung 15 unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses erzwingt demnach die Steuerungseinrichtung 18 unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses den Synchronbetrieb zwischen dem Plattenzylinder 10 und dem vom Hauptantrieb (mit Räderzug) angetriebenen Gummituchzylinder 8, alternativ dem Bogenführungszylinder 6 (Druckzylinder). Hierdurch wird erzielt, dass der Plattenzylinder 10 dem Hauptantrieb folgt. Über ein weiteres Ausgangssignal wird die Schaltkupplung 15 nach Beseitigung des sicherheitsrelevanten Ereignisses in einer zweiten Schaltstellung von dem Zahnrad 14 entkoppelt (Normalbetrieb).For this purpose, in the context of the present invention, a control device 18 is used, which is supplied with a signal as an input signal, which contains data on whether a security-relevant event is present or not. The control device 18 or a plurality of control devices 18 are preferably coupled to a control station. Such a control device 18 is directly in the presence of a safety-related event synchronous operation between the driven by the main drive blanket cylinder gear 13 and driven by the single drive M plate cylinder 10, characterized in that the control device 18 via an output signal, the clutch 15 to the freely rotatable gear 14 under adhesion closes. In this first switching position, the clutch 15 is coupled to the gear 14 and via the gear 14 with the rubber blanket gear 13. About a further output signal of the controller 18, the single drive M of the plate cylinder 10 is switched torqueless by z. B. is switched off or de-energized. By closing the non-positive clutch 15 immediately in the presence of a safety-related event, the control device 18 forces the synchronous operation between the plate cylinder 10 and the main drive (with gear train) driven blanket cylinder 8, alternatively the sheet guiding cylinder 6 (impression cylinder) immediately in the presence of a safety-relevant event. This achieves that the plate cylinder 10 the Main drive follows. About another output signal, the clutch 15 after removal of the safety-related event in a second switching position of the gear 14 decoupled (normal operation).

In Fig. 3 ist gezeigt, dass zwischen dem Formzylinder 9 und dem benachbarten Bogenführungszylinder 6 (Druckzylinder) eines Lackwerkes 2 eine kraftschlüssig wirkende Schaltkupplung 15 angeordnet ist.
Im vorliegenden Beispiel ist die Schaltkupplung 15 am Formzylinder 9 angeordnet und am Formzylinder 9 ist ferner ein frei drehbares Zahnrad 14 der Schaltkupplung 15 benachbart angeordnet. Das frei drehbare Zahnrad 14 ist mit dem Bogenführungszylinder-Zahnrad 17 des vom Hauptantrieb angetriebenen Räderzuges im ständigen Eingriff. Von Hauptantrieb und Räderzug wird auf das Bogenführungszylinder-Zahnrad 17 ein Eintrieb 16 (vom Hauptantrieb mit Räderzug) eingespeist. In einer weiteren Ausbildung kann das frei drehbare Zahnrad 14 mit der nachgeordneten Auftragwalze der Dosiereinrichtung 11 mittels einer getriebetechnischen Verbindung direkt oder mittels einer weiteren Kupplung antriebsseitig gekoppelt sein.
Im Normallackbetrieb bzw. Normaldruckbetrieb, in welchem der Formzylinder 9 eigenmotorisch vom Einzelantrieb M angetrieben wird, ist die Schaltkupplung 15 geöffnet, um so den Formzylinder 9 vom Hauptantrieb bzw. vom Bogenführungszahnrad 17 zu entkoppeln.
Zur Implementierung der notwendigen Sicherheitsmaßnahmen für den jeweils eigenmotorisch angetriebenen Plattenzylinder 10 bzw. Formzylinder 9 wird im Sinne der hier vorliegenden Erfindung vorgeschlagen, die Sicherheitsmaßnahmen des Hauptantriebs steuerungsseitig auf den eigenmotorisch angetriebenen Plattenzylinder 10 des jeweiligen Offsetdruckwerks 1 bzw. des eigenmotorisch angetriebenen Formzylinders 9 des jeweiligen Lackwerkes 2 dadurch zu vererben bzw. zu übertragen, dass bei Vorliegen eines sicherheitsrelevanten Ereignisses ein Synchronbetrieb zwischen dem vom Hauptantrieb angetriebenen Gummituchzylinder-Zahnrad 13 und dem vom Einzelantrieb M eigenmotorisch antreibbaren Plattenzylinder 10 bzw. dem vom Hauptantrieb angetriebenen Bogenführungszylinder-Zahnrad 17 und dem vom Einzelantrieb M eigenmotorisch antreibbaren Formzylinder 9 vorgegeben wird.In Fig. 3 It is shown that between the form cylinder 9 and the adjacent sheet guiding cylinder 6 (printing cylinder) of a coating unit 2, a force-acting clutch 15 is arranged.
In the present example, the clutch 15 is arranged on the forme cylinder 9 and on the forme cylinder 9, a freely rotatable gear 14 of the clutch 15 is also arranged adjacent. The freely rotatable gear 14 is in constant mesh with the sheet guiding cylinder gear 17 of the gear train driven by the main drive. From main drive and gear train is a drive 16 (from the main drive with gear train) fed to the sheet guiding cylinder gear 17. In a further embodiment, the freely rotatable gear 14 may be coupled to the downstream applicator roller of the metering device 11 by means of a transmission connection directly or by means of a further coupling on the drive side.
In solid color operation or normal pressure operation, in which the forme cylinder 9 is driven by the individual drive M, the clutch 15 is opened so as to decouple the forme cylinder 9 from the main drive or from the sheet guiding gear 17.
To implement the necessary safety measures for the respective self-propelled plate cylinder 10 or form cylinder 9 is proposed in the sense of the present invention, the safety measures of the main drive control side on the self-propelled plate cylinder 10 of the respective offset printing unit 1 and the self-propelled forme cylinder 9 of the respective coating unit 2 thereby inherit or transfer, that in the presence of a safety-related event synchronous operation between the driven by the main drive blanket cylinder gear 13 and the self-propelled by the individual drive M plate cylinder 10 and the main drive driven sheet guiding cylinder gear 17 and the self-propelled by the individual drive M form cylinder 9 is specified.

Hierzu dient im Sinne der vorliegenden Erfindung wenigstens eine Steuerungseinrichtung 18, der als Eingangssignal ein Signal zugeführt wird, welches Daten darüber enthält, ob ein sicherheitsrelevantes Ereignis vorliegt oder nicht. Jeder mit einem Einzelantrieb M gekoppelte Plattenzylinder 10 sowie Formzylinder 9 ist schaltungstechnisch bevorzugt mit je einer eigenen Steuereinrichtung 18 gekoppelt. Die Steuerungseinrichtung 18 ist bevorzugt mit einem Leitstand gekoppelt und gibt unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses einen Synchronbetrieb zwischen dem vom Hauptantrieb angetriebenen Gummituchzylinder-Zahnrad 13 bzw. Bogenführungszylinder-Zahnrad 17 und dem vom Einzelantrieb M angetriebenen Plattenzylinder 10 bzw. Formzylinder 9 dadurch vor, dass die Steuerungseinrichtung 18 über ein Ausgangssignal die Schaltkupplung 15 zum frei drehbaren Zahnrad 14 schließt und über ein weiteres Ausgangssignal den Einzelantrieb M des Plattenzylinders 10 momentenlos schaltet, indem dieser z. B. stromlos bzw. energielos geschaltet wird. Durch das Schließen der kraftschlüssigen Schaltkupplung 15 unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses erzwingt demnach die Steuerungseinrichtung 18 unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses den Synchronbetrieb zwischen dem Plattenzylinder 10 bzw. Formzylinder 9 und dem vom Hauptantrieb angetriebenen Gummituchzylinder 8 bzw. Bogenführungszylinder 6 . Hierdurch wird erzielt, dass der Plattenzylinder 10 bzw. der Formzylinder 9 dem Hauptantrieb folgt.For this purpose, within the meaning of the present invention, at least one control device 18 is used, to which a signal is fed as input signal, which contains data on whether a safety-relevant event is present or not. Each with a single drive M coupled plate cylinder 10 and forme cylinder 9 is preferably circuit technology coupled with its own control device 18. The control device 18 is preferably coupled to a control station and immediately in the presence of a safety-relevant event synchronous operation between the driven by the main drive blanket cylinder gear 13 and sheet guiding cylinder gear 17 and driven by the individual drive M plate cylinder 10 or forme cylinder 9 in that the control device 18 via an output signal, the clutch 15 to the freely rotatable gear 14 closes and via a further output signal the single drive M of the plate cylinder 10 torque-free by z. B. is switched off or de-energized. By closing the frictional clutch 15 immediately in the presence of a safety-relevant event, the control device 18 thus forces the synchronous operation between the plate cylinder 10 or forme cylinder 9 and the blanket cylinder 8 or sheet guiding cylinder 6 driven by the main drive immediately in the presence of a safety-relevant event. As a result, it is achieved that the plate cylinder 10 or the forme cylinder 9 follows the main drive.

Um beim kraftschlüssigen Schließen der Schaltkupplung 15 eine Relativbewegung der Zylinder, insbesondere in der Kontaktstelle (Druckzone, Lackierzone) des Gummituchzylinders 8 oder des Formzylinders 9 mit dem zugeordneten Bogenführungszylinder 6 (Druckzylinder) zu verhindern, wird in einer weiteren Ausbildung der Gummituchzylinder 8 oder der Formzylinder 9, vorzugsweise vorgegeben durch die Steuereinrichtung 18, in Druck ab - Position bewegt.In order to prevent the positive locking of the clutch 15, a relative movement of the cylinder, in particular in the contact point (printing zone, painting) of the blanket cylinder 8 or the forme cylinder 9 with the associated sheet guiding cylinder 6 (pressure cylinder), in a further embodiment of the blanket cylinder 8 or the forme cylinder 9, preferably predetermined by the control device 18, in pressure from - moved position.

Zusammengefasst ist die Erfindung dadurch charakterisiert, dass eine Steuerungseinrichtung 18, die unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses einen Synchronbetrieb

  • bei Druckwerken 1 zwischen den von dem Hauptantrieb und Räderzug angetriebenen Zylindern, insbesondere Bogenführungszylindern 6 oder Gummituchzylindern 8, und dem jeweiligen eigenmotorisch mittels Einzelantrieb M angetriebenen Plattenzylinder 10, oder
  • bei Lackwerken 2 zwischen den von Hauptantrieb und Räderzug angetriebenen, dem Formzylinder 9 zugeordneten Bogenführungszylinder 6 und dem jeweiligen eigenmotorisch mittels Einzelantrieb M angetriebenen Formzylinder 9,
vorgibt, indem die Steuerungseinrichtung 18 die jeweilige Schaltkupplung 15 zwischen
  • dem einem der Zylinder 6, 8, insbesondere Bogenführungszylinder 6 oder Gummituchzylinder 8 und dem Plattenzylinder 10 des jeweiligen Druckwerks 1, oder
  • dem Bogenführungszylinder 6 und dem Formzylinder 9 des jeweiligen Lackwerks 2 unter Kraftschluss schließt
und den Einzelantrieb M des Plattenzylinders 10 oder Formzylinders 9 momentenlos schaltet.In summary, the invention is characterized in that a control device 18, the synchronous operation immediately in the presence of a safety-related event
  • in printing units 1 between the driven by the main drive and gear train cylinders, in particular sheet guiding cylinders 6 or blanket cylinders 8, and the respective own motor driven by single drive M plate cylinder 10, or
  • in coating units 2 between the main drive and gear train driven, the forme cylinder 9 associated sheet guiding cylinder 6 and the respective self-propelled motor driven by single drive M forme cylinder 9,
pretends, by the control device 18, the respective clutch 15 between
  • one of the cylinders 6, 8, in particular sheet guiding cylinder 6 or blanket cylinder 8 and the plate cylinder 10 of the respective printing unit 1, or
  • the sheet guiding cylinder 6 and the forme cylinder 9 of the respective coating unit 2 closes under adhesion
and the single drive M of the plate cylinder 10 or forme cylinder 9 torqueless switches.

Als sicherheitsrelevantes Ereignis wird vorzugsweise überwacht, ob eine Schutzeinrichtung an der Bogendruckmaschine offen und damit ein Gefahrbereich an derselben zugänglich ist. Als sicherheitsrelevantes Ereignis kann jedoch auch jedes andere Signal ausgewertet werden. So kann insbesondere bei Ausfall einer Hilfsenergiequelle bzw. eines Einzelantriebes M, ein Synchronbetrieb, wie oben beschrieben, erzwungen werden. Ein unkontrolliertes Bewegen (Austrudeln) eines Zylinders nach Ausfall des Antriebsdrehmomentes des Einzelantriebs M an diesem Zylinder ist damit ebenso unterbunden. Ein zusätzlicher Vorteil ist, dass der normale Produktionsprozess (Druckbetrieb/Lackierbetrieb) nach Ausfall eines Einzelantriebs M nicht unterbrochen werden muss. Damit sind Notlaufeigenschaften des ansonsten eigenmotorisch mittels angetrieben Zylinders gewährleistet, bis die Einsatzfähigkeit des ausgefallenen Einzelantriebs M wieder gewährleistet ist.
Eine weitere Ausgestaltung erlaubt im Falle einer Überlastung des Einzelantriebs M eine Umschaltung des Plattenzylinders / Formzylinders auf den Hauptantrieb ohne Momentenpause. Hierbei wird mittels Steuerungseinrichtung 16 der Einzelantrieb M erst momentenfrei geschaltet wird, wenn die Schaltkupplung 15 unter Kraftschluss geschlossen ist.
Die in diesem Fall nicht mehr mögliche Registerung der betroffenen Zylinderachse kann über die Registerkorrektureinrichtungen anderer Zylinderachsen ausgeglichen werden.
Eine weitere Verfahrensausgestaltung erlaubt, beispielsweise zu Diagnosezwecken, den wahlweisen Antrieb des Plattenzylinders 10 bzw. Formzylinders 9 über den Hauptantrieb mit Räderzug oder über den Einzelantrieb M. Damit können die Ursachen von Änderungen der Druck- bzw. Lackierqualität im Produktionsprozess dem Bereich des Einzelantriebes M oder dem Hauptantrieb mit Räderzug, alternativ der sonstigen Maschinenperipherie - nach Analyse - zugeordnet und verändert bzw. abgestellt werden.
Bei mehreren Offsetdruckwerken 1 verfügt bevorzugt jedes Werk 1 über einen eigenmotorisch antreibbaren Plattenzylinder 10, dem jeweils ein Einzelantrieb M zugeordnet ist. Bei mehreren Lackwerken 2 verfügt bevorzugt jedes Werk 2 über einen eigenmotorisch antreibbaren Formzylinder 9, dem jeweils ein Einzelantrieb M zugeordnet ist. Es liegt dabei im Sinne der hier vorliegenden Erfindung, dass für jeden eigenmotorisch angetriebenen Plattenzylinder 10 bzw. Formzylinder 9 für jedes Offsetdruckwerk 1 sowie Lackwerk 2 separat bzw. individuell das Vorliegen mindestens eines sicherheitsrelevanten Ereignisses überwacht wird.As a security-relevant event, it is preferably monitored whether a protective device is open on the sheet-fed printing press and thus a danger zone is accessible to it. However, any other signal can be evaluated as a security-relevant event. Thus, in particular in case of failure of an auxiliary power source or a single drive M, a synchronous operation, as described above, be enforced. An uncontrolled moving (tumbling) of a cylinder after failure of the drive torque of the single drive M on this cylinder is thus also prevented. An additional advantage is that the normal production process (printing operation / painting operation) does not have to be interrupted after the failure of a single drive M. This is emergency running the otherwise self-propelled by means of driven cylinder ensures until the operational capability of the failed individual drive M is ensured again.
A further embodiment allows in the event of overloading of the single drive M switching the plate cylinder / forme cylinder on the main drive without torque break. In this case, the individual drive M is only switched torque-free by means of control device 16, when the clutch 15 is closed under adhesion.
The registration of the affected cylinder axis, which is no longer possible in this case, can be compensated for via the register correction devices of other cylinder axes.
A further process configuration allows, for example for diagnostic purposes, the optional drive of the plate cylinder 10 or forme cylinder 9 via the main drive with gear train or the single drive M. Thus, the causes of changes in printing or Lackierqualität in the production process in the field of single drive M or the main drive with gear train, alternatively the other machine peripherals - after analysis - assigned and changed or turned off.
In the case of several offset printing units 1, each work 1 preferably has a plate cylinder 10 which can be driven by its own motor, to which a single drive M is assigned. In the case of several coating units 2, each work 2 preferably has a form cylinder 9 which can be driven by an own motor, to which a single drive M is assigned. It is within the meaning of the present invention that for each self-propelled plate cylinder 10 or forme cylinder 9 for each offset printing unit 1 and coating unit 2 separately or individually the presence of at least one security-relevant event is monitored.
