Description
Die Erfindung betrifft eine Druckmaschine, insbesondere eine Bogendruckmaschine, nach dem Oberbegriff des Anspruchs 1 und ein Verfahren zum Betreiben einer Druckmaschine, insbesondere einer Bogendruckmaschine, nach dem Oberbegriff des Anspruchs 6.The invention relates to a printing machine, in particular a sheet-fed printing machine, according to the preamble of claim 1 and a method for operating a printing press, in particular a sheet-fed printing press, according to the preamble of claim 6.
Druckmaschinen verfügen über eine Vielzahl von Einrichtungen, die im Druckbetrieb, Einrichtbetrieb oder Wartungsbetrieb der Druckmaschine angetrieben werden müssen. Bei klassischen Konstellationen werden alle anzutreibenden Einrichtungen einer Druckmaschine von einem sogenannten Hauptantrieb der Druckmaschine angetrieben. Alle anzutreibenden Einrichtungen sind dann üblicherweise mechanisch über Getriebe oder Zahnriemen mit dem Hauptantrieb verbunden.Printing machines have a variety of facilities that must be driven in the printing, setup or maintenance operation of the printing press. In classical constellations all driven devices of a printing press are driven by a so-called main drive of the printing press. All devices to be driven are then usually mechanically connected via gears or toothed belt to the main drive.
Bei modernen Konzepten für 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 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 Druckmaschine, deren Druckwerke eigenmotorisch angetriebene Formzylinder aufweisen, ist aus der
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.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde eine neuartige Druckmaschine und ein Verfahren zum Betreiben derselben zu schaffen.On this basis, the present invention is based on the problem to provide a novel printing press and a method for operating the same.
Dieses Problem wird durch eine Druckmaschine gemäß Anspruch 1 gelöst. Die erfindungsgemäße Druckmaschine weist eine erste Steuerungseinrichtung auf, die unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses einen Synchronbetrieb zwischen den von dem oder jedem Hauptantrieb angetrieben Zylindern bzw. Walzen eines Druckwerks und dem jeweiligen eigenmotorisch antreibbaren Formzylinder vorgibt, nämlich dadurch, dass die erste Steuerungseinrichtung die oder jede schaltbare Kupplung zwischen dem Gummizylinder und dem Formzylinder des jeweiligen Druckwerks schließt und den Antrieb des Formzylinders momentenlos schaltet.This problem is solved by a printing machine according to claim 1. The printing press according to the invention has a first control device which, in the presence of a safety-relevant event, prescribes synchronous operation between the cylinders or cylinders of a printing unit driven by the or each main drive and the respective forme motor driven form cylinder, namely in that the first control device is the or each switchable coupling between the blanket cylinder and the forme cylinder of the respective printing unit closes and switches the drive of the forme cylinder torqueless.
Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, dass eine erste Steuerungseinrichtung unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses einen Synchronbetrieb zwischen den vom Hauptantrieb angetriebenen Einrichtungen der Druckmaschine und dem eigenmotorisch angetriebenen Formzylinder erzwingt. Der Synchronbetrieb wird dadurch erzwungen, dass die erste Steuerungseinrichtung eine Kupplung, die im Druckbetrieb der Druckmaschine geöffnet ist und den Formzylinder vom Hauptantrieb entkoppelt, schließt und den Antrieb des Formzylinders momentenlos schaltet. Hierdurch wird erzielt, dass alle Schutzmaßnahmen bzw. Sicherheitsvorgaben des Hauptantriebs auf den Antrieb der jeweiligen eigenmotorisch angetriebenen Formzylinders steuerungsseitig vererbt werden. Hierdurch lassen sich mit relativ geringem Aufwand steuerungsseitig für alle Gefährdungen aller Antriebe der Druckmaschine Schutzmaßnahmen implementieren.For the purposes of the present invention, it is proposed that a first control device force a synchronous operation between the devices of the printing press driven by the main drive and the form-cylinder driven by the motor directly in the presence of a safety-relevant event. The synchronous operation is enforced by the fact that the first control device closes a clutch, which is opened in the printing operation of the printing press and decouples the forme cylinder from the main drive, and switches the drive of the forme cylinder torque-free. This ensures that all protective measures or safety specifications of the main drive are inherited on the drive of the respective self-propelled forme cylinder controlled by the control. As a result, control measures can be implemented with relatively little effort on the control side for all hazards of all drives of the printing press.
Nach einer vorteilhaften Weiterbildung der Erfindung weist die erfindungsgemäße Druckmaschine eine zweite Steuerungseinrichtung auf, die unabhängig von der ersten Steuerungseinrichtung nach Ablauf einer definierten Zeitspanne nach Vorliegen des sicherheitsrelevanten Ereignisses einen Synchronbetrieb zwischen den von dem oder jedem Hauptantrieb angetrieben Zylindern bzw. Walzen eines Druckwerks und dem jeweiligen eigenmotorisch antreibbaren Formzylinder dadurch vorgibt, dass die zweite Steuerungseinrichtung die oder jede schaltbare Kupplung zwischen dem Gummizylinder und dem Formzylinder des jeweiligen Druckwerks schließt und den Antrieb des Formzylinders momentenlos schaltet.According to an advantageous development of the invention, the printing machine according to the invention has a second control device which, independently of the first control device after a defined period of time after the presence of the safety-relevant event synchronous operation between the driven by the or each main drive cylinders or rollers of a printing unit and the respective own cylinder drivable form cylinder dictates that the second control device closes the or each switchable coupling between the blanket cylinder and the forme cylinder of the respective printing unit and the drive of the forme cylinder torque-free switches.
Das erfindungsgemäße Verfahren zum Betreiben einer Druckmaschine ist in Anspruch 6 definiert.The inventive method for operating a printing press is defined in claim 6.

Es wird demnach über zwei unabhängig voneinander arbeitende Steuerungseinrichtungen 15 und 19 bei Vorliegen eines sicherheitsrelevanten Ereignisses ein Synchronbetrieb zwischen dem Formzylinder 12 und dem vom Hauptantrieb 10 angetriebenen Gummizylinder 11 erzwungen. Die erste Steuerungseinrichtung 15 gibt dabei unmittelbar bei Vorliegen eines sicherheitsrelevanten Ereignisses den Synchronbetrieb vor. Die zweite Steuerungseinrichtung 19 erzwingt den Synchronbetrieb erst nach Ablauf einer definierten Zeitspanne, die vorzugsweise in der Größenordnung von einigen Sekunden liegt.It is therefore enforced via two independently

Stellt die zweite Steuerungseinrichtung 19 hierbei fest, dass die erste Steuerungseinrichtung 15 nicht ordnungsgemäß arbeitet, so kann eine Fehlermeldung bzw. ein Warnhinweis generiert werden. Von der zweiten Steuerungsrichtung kann zusätzlich auch das zweite Ausgangssignal 18 der ersten Steuerungseinrichtung 15 gelesen werden, um den ordnungsgemäßen Betrieb der ersten Steuerungseinrichtung 15 zu überwachen. Durch Vergleich des erzwungenen Synchronlaufs bei geschlossener Kupplung 14 kann in der ersten Steuerungseinrichtung 15 der ordnungsgemäße Betrieb der Kupplung 14 überwacht werden, wobei dann, wenn hierbei ein Fehler der Kupplung 14 festgestellt wird, wiederum ein Warnhinweis bzw. eine Fehlermeldung generiert werden kann.According to an advantageous development of the present invention, the
