Description

Die Erfindung betrifft eine Steuerung für eine Druckmaschine, insbesondere Bogenoffsetdruckmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a controller for a printing press, in particular a sheet-fed offset printing press according to the preamble of claim 1.

Bogenoffsetdruckmaschinen der heute weit verbreiteten Art weisen in der Regel sogenannte Zentralsteuerungen auf, welche insbesondere in Form einer SPS- bzw. PC-Board-Steuerung aufgebaut sind. Auch ist es bekannt, die Steuerung der Druckmaschine funktional aufzuteilen. So kann ein Rechner vorgesehen sein, der permanent die Schaltzustände bzw. Signale von Aktuatoren, Bedientastern bzw. Sensoren einliest und ein zweiter Rechner insbesondere den Hauptantrieb sowie die aufden Drehwinkel von bewegten Maschinenteilen bezogenen Schaltvorgange der Druckmaschine steuert. Als sogenannte drehwinkelabhängige Schaltfunktionen seien hier beispielhaft das Druck-An-/Druck-Abstellen das An- und Abstellen von Farb- und Feuchtauftragwalzen, das Sperren des Bogeneinlaufes, das Schalten des Anlegers sowie das Schalten bestimmter Funktionen im Ausleger genannt. Diese Schaltvorgänge sind zeitkritisch, d.h. insbesondere das Anstellen des eingefärbten Gummituchzylinders an den bogentragenden Gegendruckzylinder darf nur während der Kanalkorrespondenz der Zylinder folgen, wenn also der erste zu bedruckende Bogen bereits aufdem Gegendruckzylinder liegt.Sheet-fed offset printing presses of the type which are widely used today generally have so-called central controls, which are constructed in particular in the form of a PLC or PC board control. It is also known to divide the control of the printing press functionally. Thus, a computer can be provided which permanently reads the switching states or signals from actuators, control buttons or sensors and controls a second computer in particular the main drive and the switching operations of the printing press related to the angle of rotation of moving machine parts. As so-called rotation-dependent switching functions, the printing on / printing off, the switching on and off of ink and dampening rollers, the blocking of the sheet inlet, the switching of the feeder and the switching of certain functions in the delivery are examples. These switching operations are time-critical, i.e. in particular, the positioning of the inked blanket cylinder on the sheet-bearing impression cylinder may only follow the cylinder during channel correspondence, that is, when the first sheet to be printed is already on the impression cylinder.

Nachteilig bei derartig zentral aufgebauten und eine Folgeschaltung realisierenden Steuerung ist dabei, daß der Programmaufbau im Rechner der Steuerung exakt auf die Konfiguration der Maschine abgestellt sein muß. Eine Bogendruckmaschine mit einer unterschiedlichen Zahl von Druckwerken bedingt somit eine unterschiedliche Programmierung der entsprechenden Steuerung. Dieser Sachverhalt kompliziert sich dadurch erheblich, das heutzutage ein deutlicher Trend zur sogenannten In-Line-Veredelung bzw. Weiterverarbeitung besteht. Bei Bogenoffsetdruckmaschinen sind häufig nach dem letzten Druckwerk und vor dem Ausleger ein oder mehrere Lackiereinrichtungen oder sonstige Beschichtungswerke zwischengeschaltet. Da auch in diesen Einrichtungen drehwinkelstellungsabhängige Schaltvorgänge auszuführen, muß auch diese Funktion von der Zentralsteuerung übernommen werden.A disadvantage of such a centrally constructed control system which implements a sequential circuit is that the program structure in the computer of the control system must be geared precisely to the configuration of the machine. A sheetfed press with a different number of printing units therefore requires different programming of the corresponding control. This fact is complicated considerably by the fact that there is now a clear trend towards so-called in-line finishing or further processing. In sheetfed offset presses there are often one or more after the last printing unit and before the delivery Painting facilities or other coating plants interposed. Since switching operations dependent on the angle of rotation position must also be carried out in these devices, this function must also be taken over by the central control.

Aus der DE 3 815 534 A1 ist eine Zentralsteuerung der oben kurz umrissenen Art bekannt, welche ein System zur Erfassung der Position von beweglichen Maschinenteilen aufweist. Dazu werden die Signale eines an einer eintourig drehenden Welle der Maschine angebrachten Inkrementalgebers ausgewertet. Ausgewertet werden bei diesem System dabei nicht nur die um 90° phasenverschobenen Rechtecksignale des Inkrementalgebers sondern zusätzlich auch noch die sogenannten Null-Impulse, welche jeweils bei einer vollen, eintourigen Maschinenumdrehung anfallen. Eine Zentralsteuerung mit einem derartigen System weist die zuvor genannten Nachteile auf. Anstelle eines Inkrementalgebers kann zur Erfassung der Stellung von beweglichen Maschinenteilen auch ein sogenannter Absolut-Winkelgeber verwendet werden. Dies ändert jedoch nichts an der Komplexität der Steuerung, die sich ergibt, wenn eine Druckmaschine individuell mit einer verschiedenen Anzahl von Aggregaten ausgestattet wird.A central control of the type briefly outlined above is known from DE 3 815 534 A1, which has a system for detecting the position of moving machine parts. For this purpose, the signals of an incremental encoder attached to a single-rotating shaft of the machine are evaluated. This system not only evaluates the square-wave signals of the incremental encoder, which are phase-shifted by 90 °, but also also the so-called zero pulses, which occur each time a full, single-revolution machine revolution. A central control with such a system has the aforementioned disadvantages. Instead of an incremental encoder, a so-called absolute angle encoder can also be used to record the position of moving machine parts. However, this does not change the complexity of the control that arises when a printing press is individually equipped with a different number of units.

Aus der EP 0 543 281 A1 ist eine Steuerung für Rotationsdruckmaschinen bekannt, bei welcher jedem Anlageteil ein die Steuerung darstellender Rechner zugeordnet ist und diese Rechner in den einzelnen Anlageteilen zwecks Signalaustausch über ein als Netzwerk bezeichnetes Bus-System miteinander verbunden sind. Als Vernetzungsschnittstelle zwischen den einzelnen Rechnern wird ARCNET mittels Koaxkabel vorgeschlagen. Wie einzelne drehwinkelabhängige Schaltvorgänge auszuführen sind, ist in dieser Schrift jedoch nicht beschrieben.A control for rotary printing presses is known from EP 0 543 281 A1, in which a computer representing the control is assigned to each system part and these computers are connected to one another in the individual system parts for the purpose of signal exchange via a bus system called a network. ARCNET using coax cables is proposed as the networking interface between the individual computers. However, this document does not describe how individual switching operations dependent on the angle of rotation are to be carried out.

Aufgabe der vorliegenden Erfindung ist es daher, eine Steuerung gemäß dem Oberbegriff von Anspruch 1 derartig zu erweitern, so daß die zuvorstehend beschriebenen Nachteile vermieden werden können und eine hohe Flexibilität hinsichtlich der Ausrüstung der Maschine erzielbar ist.The object of the present invention is therefore to expand a control according to the preamble of claim 1 in such a way that the disadvantages described above can be avoided and a high degree of flexibility with regard to the equipment of the machine can be achieved.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by the characterizing features of claim 1. Further developments of the invention result from the subclaims.

Gemäß der Erfindung ist vorgesehen, daß neben dem die einzelnen Stationen vernetzenden Bus ein weiterer Bus vorgesehen ist, über welchen die Signale der Winkelstellung eines Winkelgebers übertragbar sind, wobei dieser Winkelgeber an einem eintourig rotierenden Maschinenteil der Druckmaschine angebracht ist. Durch dieses Winkelstellungswerte übertragende Bus-System erhält jede einzelne Station die Information über den aktuell vorliegenden Winkelwert. In den einzelnen Stationen sind entsprechend den über den Bus übertragbaren Ereignissen Soll-Winkelstellungswerte abgespeichert, so daß die einzelnen Stationen die vorgesehenen Schaltvorgänge in den zugeordneten Einheiten auslösen können. Als Beispiel sei hier das folgerichtige Druck-Ab-Schalten bei einem Fehlbogen/Schiefbogen und das Auskoppeln des Anlegers genannt.According to the invention it is provided that in addition to the bus networking the individual stations, a further bus is provided, via which the signals of the angular position of an angle transmitter can be transmitted, this angle transmitter being attached to a single-part rotating machine part of the printing press. This bus system, which transmits angular position values, provides each individual station with information about the current angular value. Target angular position values are stored in the individual stations in accordance with the events which can be transmitted via the bus, so that the individual stations can trigger the intended switching operations in the assigned units. As an example, here is the logical switching off of pressure in the case of a missed / skewed sheet and the coupling of the feeder.

Gemäß einer Weiterbildung der Erfindung kann vorgesehen sein, daß in einer Einheit der Druckmaschine an einem eintourig rotierenden Maschinenteil ein sogenannter Inkrementalwinkelgeber angeordnet ist. Das erfindungsgemäß vorgesehene Bus-System umfaßt eine Anzahl von Leitungen, über welche die einzelnen gegeneinander phasenverschobenen Inkrementalsignale gesendet werden. Das erfindungsgemäße Bus-System weist ferner eine weitere Leitung auf, über welche nach jeder vollen Maschinenumdrehung ein sogenannter Null-Impuls gesendet wird. Durch ein derartiges Bus-System ist gewährleistet, daß in den einzelnen Stationen auch Schaltvorgänge auflösbar sind, welche erst nach einer bestimmten Anzahl von eintourigen Maschinenumdrehungen, ausgehend vom festgestellten Ereignis, auszuführen sind. Hier sei wiederum als Beispiel das dem Papierlaufentsprechende folgerichtige Zu- bzw. Abschalten der Druckwerkszylinder genannt.According to a development of the invention it can be provided that a so-called incremental angle encoder is arranged in a unit of the printing press on a single-speed rotating machine part. The bus system provided according to the invention comprises a number of lines via which the individual incremental signals which are phase-shifted with respect to one another are sent. The bus system according to the invention also has a further line via which a so-called zero pulse is sent after each full machine revolution. Such a bus system ensures that switching operations can also be resolved in the individual stations, which are only to be carried out after a certain number of single-revolution machine revolutions, starting from the determined event. Here again, as an example, the corresponding switching on and off of the printing unit cylinders corresponding to the paper run should be mentioned.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung kann vorgesehen sein, daß in einer Einheit der Druckmaschine an einem eintourig umlaufenden Maschinenteil ein sogenannter Absolut-Winkelgeber angebracht ist, dem die der Winkelstellung entsprechenden Digital-Werte parallel oder auch seriell entnehmbar sind. Das erfindungsgemäß vorgesehene Bus-System ist dann als ein an die Auflösung des Absolut-Winkelgebers angepaßtes paralleles bzw. serielles Bus-System ausgebildet. Auch hier ist weiterbildend vorgesehen, daß über das Bus-System nicht nur Winkelwerte innerhalb einer Maschinenumdrehung aufgelöst übertragen werden, sondern zusätzlich auch Signale, welchejeweils einer vollen Maschinenumdrehung entsprechen.According to a further preferred embodiment of the invention, it can be provided that in a unit of the printing press, a so-called absolute angle encoder is attached to a single-rotating machine part, from which the digital values corresponding to the angular position can be taken in parallel or in series. The bus system provided according to the invention is then designed as a parallel or serial bus system adapted to the resolution of the absolute angle encoder. Here, too, it is further developed that not only angular values are transmitted resolved within one machine revolution via the bus system, but also signals which correspond in each case to one full machine revolution.

Voranstehend wurde dargelegt, daß vom Inkremental- bzw. Absolutwinkelgeber lieferbarer Nullimpuls zur Feststellung ganzzahliger Maschinenumdrehungen herangezogen werden kann. Bei Inkremental- bzw. Absolutwinkelgebern ist es aber auch möglich, ganzzahlige Maschinenumdrehungen durch Summieren der Winkelimpulse bzw. durch einen vorgegebenen Winkelwert des Absolutgebers zu definieren.It was explained above that the zero pulse that can be supplied by the incremental or absolute angle encoder can be used to determine integer machine revolutions. In the case of incremental or absolute angle encoders, however, it is also possible to define integer machine revolutions by summing the angular pulses or by a predetermined angular value of the absolute encoder.

Wie bereits voranstehend aufgezeigt, werden über das erfindungsgemäße Bus-System den einzelnen Stationen in den Einheiten die Winkelwerte eines an einem eintourig rotierenden Maschinenbauteil angebrachten Winkelgebers zugeführt. Unter einem eintourig rotierenden Maschinenbauteil der Druckmaschine ist insbesondere der Plattenzylinder, der Gummituchzylinder, der einfach große Gegendruckzylinder oder beispielsweise eine eintourig laufende Anlegtrommel zu verstehen.As already shown above, the angular values of an angle encoder attached to a single-speed rotating machine component are supplied to the individual stations in the units via the bus system according to the invention. A single-component rotating machine component of the printing press is to be understood in particular to mean the plate cylinder, the blanket cylinder, the simply large impression cylinder or, for example, a single-drum feed drum.

Nach einer Weiterbildung der Erfindung ist vorgesehen, daß der neben dem die Winkelwerte übertragenen Bus-System vorhandene Bus als ein ereignisgesteuertes, nachrichtenorientiertes Kommunikationssystem, also als ein Bus-System mit einem nachrichtenorientierten Protokoll ausgebildet ist. Bevorzugt findet hier der CAN-Bus (Controller - Area - Network) Verwendung. Durch einen derartig ausgebildeten Bus ist es möglich, daß eine Station, welche durch Sensoren oder sonstige Kontrollmittel ein bestimmtes Ereignis feststellt, über diesen CAN-Bus eine Nachricht dieses Ereignisses übermittelt und die Stationen sodann in den zugeordneten Einheiten die vorgesehenen winkelabhängigen Schaltvorgange auslösen. Hier sei beispielsweise die Feststellung eines Fehlbogens/Schiefbogens an der Anlage des ersten Druckwerkes oder ein Bogenverlust zwischen dem zweiten und dritten Druckwerk genannt. Die der jeweiligen Einheit zugeordnete und das Ereignis feststellende Station sendet nun über das Bus-System die Nachricht "Fehlbogen" bzw. "Schiefbogen" bzw. "Bogenverlust zwischen DW 2 und DW 3" an die übrigen Stationen. Im Falle eines Fehlbogens/Schiefbogens löst nun die dem ersten Druckwerk zugeordnete Station die winkelabhängig zu schaltenden Vorgänge im ersten Druckwerk (z.B. Druck-Ab) aus.According to a development of the invention, it is provided that the bus, which is present in addition to the bus system transmitting the angle values, is designed as an event-controlled, message-oriented communication system, that is to say as a bus system with a message-oriented protocol. The CAN bus (controller - area - network) is preferably used here. Such a bus makes it possible for a station which detects a specific event by sensors or other control means to transmit a message of this event via this CAN bus, and the stations then trigger the intended angle-dependent switching processes in the assigned units. Here, for example, the detection of a missing sheet / inclined sheet in the system of the first printing unit or a sheet loss between the second and third printing units may be mentioned. The station assigned to the respective unit and determining the event now sends the message "missed sheet" or "skewed sheet" or "sheet loss between DW 2 and DW 3" to the other stations via the bus system. In the case of a misfed / skewed sheet, the station assigned to the first printing unit now triggers the angle-dependent processes in the first printing unit (e.g. print down).

Entsprechend den in den übrigen Stationen für die empfangende Nachricht abgespeicherten Soll-Winkelstellungswerten lösen nun diese die jeweiligen Schaltvorgängen in denen im zugeordneten Einheiten aus (z.B. folgerichtiges Druck-Ab in dem dem ersten Druckwerk nachgeordneten Druckwerken sowie Auskuppeln des Anlegers).According to the target angular position values stored in the other stations for the receiving message, these now solve the respective switching processes in which in the assigned units (eg consistent print-Ab in the print units downstream of the first printing unit and disengagement of the feeder).

So übernimmt die Station 1' sämtliche Schaltfunktionen für die den Anleger darstellende Einheit 1. Hier sei insbesondere das phasenrichtige An- und Abschalten des Anlegers erwähnt. Die Stationen 2', 3' und 4' übernehmen in den Druck- bzw. Lackierwerken der Einheiten 2 bis 4 die entsprechenden An- und Abstellvorgänge der dort angeordneten Zylinder. Die Station 5' übernimmt in der den Ausleger der Bogendruckmaschine darstellenden Einheit 5 sämtliche für den Ausleger relevanten Schaltvorgänge wie insbesondere das aufdem Bogenlauf abgestimmte, d.h. also auch zu einer bestimmten Winkelstellung erfolgende Schalten von Mitteln für einen automatisierten Stapelwechsel bzw. eine Probebogenentnahme. Die Station 2' in der das erste Druckwerk darstellenden Einheit 2 steht zusätzlich noch mit Sensoren für die Bogenankunft an der Anlage in Verbindung - dargestellt ist hier lediglich eine Bogenkontrolle 9. Die einzelnen Stationen 1' bis 5' sind zum Signalaustausch über einen Bus 6 miteinander verbunden, wobei dieser Bus 6 als ein Nachrichtenbus (CAN-Bus/Controller Area - Network) ausgebildet ist. Über den Bus 6 sind die einzelnen Stationen 1' - 5' zusätzlich noch mit einem nicht dargestellten Leitstandrechner sowie dem Hauptantrieb der Maschine verbunden, so daß Daten für Voreinstellungen u. dgl. an die einzelnen Rechner und Laufkomandos an den Antrieb weiterleitbar sind.In Fig. 1 with 1 to 5 individual units of a sheet-fed offset printing machine are indicated, unit 1 being the feeder, units 2 and 3 offset printing units, unit 4 being a coating unit and unit 5 being a delivery unit. The individual units 1 to 5 are each assigned at least one computer 1 'to 5', which trigger the switching functions in the individual units 1 to 5 via interfaces and actuating means, not shown. The station 1 'thus takes over all switching functions for the unit 1 representing the investor. In particular, the phase-correct switching on and off of the investor should be mentioned. Stations 2 ', 3' and 4 'in the printing or coating units of units 2 to 4 take over the corresponding starting and stopping processes of the cylinders arranged there. The station 5 'takes over in the unit 5 representing the delivery of the sheet-fed printing press all switching operations relevant for the delivery, in particular the switching of means for an automated stack change or a sample sheet removal which is coordinated with the sheet travel, ie also for a certain angular position. The station 2 'in the unit 2 representing the first printing unit is also connected to sensors for the sheet arrival at the system - only one sheet control 9 is shown here. The individual stations 1' to 5 'are for signal exchange with one another via a bus 6 connected, this bus 6 being designed as a message bus (CAN bus / controller area - network). Via the bus 6, the individual stations 1 '- 5' are also included a control center computer, not shown, and the main drive of the machine connected, so that data for presets u. Like. Can be forwarded to the individual computers and running commands to the drive.

Die Station 2' der das erste Druckwerk darstellenden Einheit 2 der Bogenoffsetdruckmaschine weist einen an einer eintourigen Welle angebrachten Winkelgeber 7 auf, der zum einen direkt mit der Station 2' verbunden ist und zum anderen über ein noch weiter untenstehend erläuterten und die Winkelwerte dieses Gebers übertragenen Bus 8 an die übrigen Stationen 1', 3', 4' und 5' geschaltet ist. Jede der Stationen 1' bis 5' weist dabei entsprechende, als Interface ausgebildete Einrichtungen auf, vermittels der die Signale des Winkelgebers 7 ständig erfaßt und eingelesen werden können.The station 2 'of the unit 2 of the sheetfed offset printing machine which represents the first printing unit has an angle transmitter 7 which is attached to a single-speed shaft and which is connected on the one hand directly to the station 2' and on the other hand via a transmitter which is explained further below and transmits the angle values of this transmitter Bus 8 is connected to the other stations 1 ', 3', 4 'and 5'. Each of the stations 1 'to 5' has corresponding devices designed as an interface, by means of which the signals from the angle transmitter 7 can be continuously detected and read.

Des weiteren erfolgt die Funktionweise der hier dargestellten Ausführungsvariante der Erfindung am Beispiel eines sogenannten Fehlbogens. Unter einem Fehlbogen wird dabei ein Ausbleiben eines Bogens an der Anlage bei laufender Maschine verstanden. Bei einem solchen Fehlbogen ist es somit unbedingt nötig, daß in den einzelnen Druckwerken die Gummituchzylinder von den Gegendruckzylinder abgestellt werden, um ein Einfarben der Gegendruckzylinder zu verhindern. Auch der den Lackauftrag bewirkende Zylinder in dem Lackwerk (Einheit 4) muß abgestellt werden. Die beschriebenen Abstellvorgänge haben dabei dem Bogenlauf entsprechend folgerichtig zu erfolgen, damit die noch korrekt in die Maschine einlaufenden Bogen ausgedruckt werden.Furthermore, the functioning of the embodiment variant of the invention shown here takes place using the example of a so-called missing sheet. A missed sheet is understood to mean a sheet missing on the system when the machine is running. In the case of such a missing sheet, it is therefore absolutely necessary that the blanket cylinders in the individual printing units are switched off from the impression cylinders in order to prevent the impression cylinders from inking. The cylinder in the coating unit (unit 4) that applies the paint must also be switched off. The described shutdown processes have to be carried out in accordance with the sheet travel, so that the sheets that are still correctly entering the machine are printed out.

Die Station 2' der das erste Druckwerk darstellenden Einheit 2 steht mit einer Bogenkontrolle 9 in Verbindung und wertet das Signal dieser Bogenkontrolle 9 permanent aus. Zu einem bestimmten Zeitpunkt wird durch die Station 2' ein Ausbleiben des Bogens, also ein Fehlbogen festgestellt. In einem Speicher der als Rechner ausgebildeten Station 2' sind Winkelwerte abgelegt, welche denjenigen Werten entsprechen, zu denen das Abstellen der Druckwerkszylinder in der Einheit 2 zu erfolgen hat. Die Station 2' bewirkt nun bei den entsprechend vorgegebenen Winkelwerten das Sperren der Anlage, des Vorgreifers sowie daraufhin das Abstellen des Gummituchzylinders vom Gegendruckzylinder und das Abstellen gegenüber dem Plattenzylinder im ersten Druckwerk.The station 2 'of the unit 2 which represents the first printing unit is connected to a sheet control 9 and continuously evaluates the signal of this sheet control 9. At a certain point in time, station 2 'detects the absence of the sheet, that is to say a missing sheet. Angle values are stored in a memory of the station 2 'designed as a computer, which correspond to those values at which the printing unit cylinders have to be switched off in the unit 2. The station 2 'now effects the locking of the system, the pre-gripper and then the blanket cylinder from the impression cylinder and the parking relative to the plate cylinder in the first printing unit at the corresponding predetermined angle values.

Während des Zeitpunktes, zu welchem durch die Station 2' der Fehlbogen festgestellt worden ist, gibt die Station 2' ein das Ereignis "Fehlbogen im ersten Druckwerk" entsprechendes Signal auf den Bus 6. In den Speicher der Stationen 1', 3', 4' und 5' sind ebenfalls Winkelwerte abgespeichert, bei welchen in diesen Einheiten 1, 3, 4, 5 vorzunehmende Schaltmaßnahmen auszuführen sind. Nachdem die Station 1 über den Bus 6 das Ereignis "Fehlbogen im ersten Druckwerk" empfangen hat, wird durch die Station 1' der Anleger abgeschaltet. Nach einer dem Bogenlauf entsprechenden Anzahl von Umdrehungen wird durch die ebenfalls die Nachricht "Fehlbogen im ersten Druckwerk" empfangenen Stationen 3', 4', 5' zur vorgesehenen, abgespeicherten Winkelwerten das Druck-Abstellen eingeleitet. Dazu werten die Stationen 1' bis 5' sowohl die Winkelsignale innerhalb einer Umdrehung als auch die Anzahl der Umdrehungen insgesamt aus.During the time at which the missed sheet was detected by station 2 ', station 2' outputs a signal corresponding to the "missed sheet in the first printing unit" event on bus 6. In the memory of stations 1 ', 3', 4 'and 5' are also stored angle values at which switching measures to be carried out in these units 1, 3, 4, 5 are to be carried out. After station 1 has received the "Missing sheet in the first printing unit" event via bus 6, station 1 'switches off the feeder. After a number of revolutions corresponding to the sheet travel, the stations 3 ', 4', 5 ', which also receive the message "Missing sheet in the first printing unit", initiate printing shutdown for the stored angle values provided. For this purpose, stations 1 'to 5' evaluate both the angle signals within one revolution and the total number of revolutions.

Beim zuvorstehend aufgezeigten Ausführungsbeispiel der Erfindung wurde das Druck-Abstellen bei einem Fehlbogen beschrieben. Entsprechend dem aufgezeigten Ablauf werden auch die sonstigen Schaltvorgänge in den einzelnen Einheiten 1 bis 5 eingeleitet. Wesentlich ist hierbei, daß die einzelnen Stationen 1' bis 5' permanent die Winkelstellungswerte des Winkelgebers 7 einlesen und über den Nachrichtenbus eine dem Ereignis entsprechend Nachricht von einer der Stationen 1' bis 5' an die übrigen Stationen 1' bis 5' gesendet wird und dabei jede der Stationen 1' bis 5' die erforderlichen Schaltvorgänge in den zugehörigen Einheiten 1 bis 5 durch einen Vergleich der erfaßten aktuellen mit den entsprechend gespeicherten Winkelwerten selbständig ausführt. Ein weiterer Vorteil der permanenten Erfassung und Auswertung der Winkelstellungssignale in den einzelnen Stationen 1' bis 5' liegt ferner darin, daß die einzelnen Stationen 1' bis 5' auch unabhängig vom Vorliegen bzw. Empfangen einer Nachricht / eines Ereignisses winkelabhängige Schaltfunktionen in den zugehörigen Einheiten ausführen können. Hier sei als Beispiel das Steuern der Pendelbewegung einer Heberwalze, das schrittweise Antreiben einer Duktorwalze, das aufdem Bogenlauf abgestimmte Pudern mittels elektronisch ansteuerbare Antriebe oder sonstigen Einrichtungen während des normalen Druckvorganges genannt. Eine derartig erfindungsgemäß aufgebaute dezentrale Steuerung gestaltet sich dabei sehr vorteilhaft bei sogenannten zeitkritischen Funktionen.In the exemplary embodiment of the invention shown above, the printing shutdown in the case of a missing sheet has been described. In accordance with the sequence shown, the other switching operations in the individual units 1 to 5 are also initiated. It is essential here that the individual stations 1 'to 5' permanently read in the angular position values of the angle transmitter 7 and via the message bus a message corresponding to the event is sent from one of the stations 1 'to 5' to the other stations 1 'to 5' and each of the stations 1 'to 5' independently carries out the required switching operations in the associated units 1 to 5 by comparing the detected current with the correspondingly stored angle values. Another advantage of the permanent detection and evaluation of the angular position signals in the individual stations 1 'to 5' is that the individual stations 1 'to 5' also have angle-dependent switching functions in the associated units, regardless of the presence or reception of a message / event can execute. Examples include the control of the pendulum movement of a lifting roller, the gradual driving of a duct roller, the powder coordinated with the sheet travel by means of electronically controllable drives or other devices during the normal printing process. A decentralized control system constructed in this way according to the invention is very advantageous in the case of so-called time-critical functions.

Fig. 2 zeigt eine Ausführungsform der Erfindung, wobei hier der Winkelgeber 7 als ein sogenannter Inkrementalgeber ausgebildet ist. Auch hier ist der Winkelgeber 7 in der das erste Druckwerk der Bogenoffsetdruckmaschine darstellenden Einheit 2 eintourig angebracht. Über insgesamt drei Leitungen werden der Station 2' der Einheit 2 die jeweils um 90° gegeneinander phasenverschobenen Inkrementalsignale der Spur A und B und ein sogenannter Null-Impuls auf der Spur N zugeleitet. Der erfindungsgemäß vorgesehene Bus zur Übertragung der Winkelstellungswerte an die übrigen Stationen 1', 3', 4', 5' weist dabei ebenfalls drei Leitungen so daß auch hier die Inkrementalsignale der Spuren A und B als auch die eintourigen Null-Impulse N übertragbar sind.Fig. 2 shows an embodiment of the invention, wherein the angle encoder 7 is designed as a so-called incremental encoder. Here, too, is the angle encoder 7 first printing unit of the sheet-fed offset printing unit 2 attached single-speed. Via a total of three lines, station 2 'of unit 2 is fed the incremental signals of track A and B, each phase-shifted by 90 ° relative to one another, and a so-called zero pulse on track N. The bus provided according to the invention for transmitting the angular position values to the other stations 1 ', 3', 4 ', 5' also has three lines so that the incremental signals of tracks A and B as well as the single-speed zero pulses N can also be transmitted here.

Die Fig. 3 zeigt ein weiteres Ausführungsbeispiel der Erfindung, wobei hier ein Winkelgeber 7 Verwendung findet, der als sogenannter Absolut-Winkelgeber ausgebildet ist. Bei diesem Ausführungsbeispiel ist vorgesehen, daß dieser Winkelgeber 7 über den als paralleles Bus-System ausgebildeten Bus 8 die Winkelwerte an die Stationen 1' bis 5' weiterleitet. Der erfindungsgemäße Bus 8 zur Übertragung der Winkelstellung an die einzelnen Stationen 1' bis 5' weist entsprechend dem Auflösungsvermögen des Winkelgebers 7 eine Anzahl von Leitungen auf, wobei vorgesehen sein kann, daß auf einer weiteren Leitung ebenfalls ein sogenannter Null-Impuls übertragen wird, aus dem die einzelnen Stationen 1' - 5' die Anzahl eintouriger Umdrehungen der Druckmaschine ableiten können. Auch im Ausführungsbeispiel gemäß der Fig. 3 ist der Winkelgeber 7 an der das erste Druckwerk der Bogenoffsetdruckmaschine darstellende Einheit 2 angebracht.3 shows a further exemplary embodiment of the invention, an angle encoder 7 being used here, which is designed as a so-called absolute angle encoder. In this exemplary embodiment, it is provided that this angle transmitter 7 forwards the angle values to the stations 1 'to 5' via the bus 8 designed as a parallel bus system. The bus 8 according to the invention for transmitting the angular position to the individual stations 1 'to 5' has a number of lines corresponding to the resolving power of the angle transmitter 7, it being possible for a so-called zero pulse to be transmitted on a further line from which the individual stations 1 '- 5' can derive the number of single-revolution revolutions of the printing press. In the exemplary embodiment according to FIG. 3, the angle transmitter 7 is also attached to the unit 2 which represents the first printing unit of the sheet-fed offset printing press.
