Definitions
- the invention relates to the field of printing technology. It relates in particular to a rotary printing press with individually driven cylinders.
- the object of the present invention is now to provide a directly driven rotary printing press which has the advantages mentioned above and avoids the disadvantages of the complexity, the susceptibility to faults and the lack of flexibility of the control system due to its special design.
- the advantage of the structure according to the invention is that the entire control system of the rotary printing press becomes very simple and susceptible to faults by combining the individual drives into arbitrary printing point groups via a fast bus system.
- the individual printing point groups are independent of each other and obtain their position reference from the folder assigned to them.
- the management of the pressure point groups takes place via a higher-level control system and only includes the specification of setpoints and setpoint deviations as well as the processing of actual values.
- the entire control system of a directly driven rotary printing press is so complicated because the cylinders have to be positioned with an accuracy of 0.05 mm at a cylinder peripheral speed of 13 m / s.
- the data transmission speed of the connecting bus system is subject to the same high demands. Only the inventive division of the entire control system into drive groups, the components of which are connected via a fast bus system, for the time-critical control and a higher-level control system, which may easily have a lower data transmission speed, for the non-time-critical tasks such as the specification of setpoints and setpoint deviations and The processing of actual values allows a simple and robust structure despite the high accuracy requirements.
- Another advantage of the arrangement according to the invention is that the machine can be flexibly configured, since there is no need to take mechanical connections into account.
- the entire control system is therefore not totally networked, but has clear interfaces. As a result, it is also insensitive to malfunctions, for example of an individual drive, since these only affect a single pressure point group.
- the essence of the invention is therefore to provide a directly driven rotary printing press which is characterized by the simplicity and robustness of the control system. This is achieved by dividing the entire control system into autonomous pressure point groups and a higher-level control system.
- the individual drives of the cylinders and their drive controllers within a pressure point group are connected via a fast bus system, adapted to the time-critical tasks.
- the pressure point groups are connected to each other and to the higher-level control system via a higher-level bus system.
- This bus system can have a lower data transmission speed, since it only has to deal with non-time-critical tasks.
- the printing point groups get their position reference directly from the assigned folder.
- the relative position of the cylinders of a pressure point group to each other is set independently of the higher-level control system via the fast bus system.
- the individual pressure point groups therefore have a high degree of autonomy during operation.
- the entire control system Due to the aforementioned division of the entire control system into a higher-level control system and autonomous pressure point groups, the entire control system has one The degree of simplicity, flexibility and robustness against malfunctions, which is necessary for the implementation of a directly driven rotary printing press.
- each cylinder in particular the impression and impression cylinders and the folder, are driven by their own electric motor. This eliminates the mechanical connections.
- the individual drives must of course be coordinated with each other. Due to the high demands on the positioning accuracy, the connecting bus system must have a high data transmission speed.
- the most obvious approach to regulating all drives with a single higher-level central unit fails because of the complexity and the limited flexibility. A completely different approach is now assumed for the rotary printing press according to the invention. This will be explained in connection with the figures.
- FIG. 1 shows a block diagram of a rotary printing press according to the invention. It has k pressure point groups (2a-d) which are connected via a data bus (3) both to the operating and data processing unit (1) and to the folder (12). The individual drives of the cylinders and their drive controllers are combined into pressure point groups (2a-d). Only these pressure point groups (2a-d) are connected to the operating and data processing unit, ie to the higher-level control system (1). The printing point groups obtain their position reference directly from the folder (12). So you have a high degree of autonomy.
- FIG. 2 shows a block diagram of an individual pressure point group (2).
- the drive controllers (6a-d) are via a fast bus system Drive bus (5) connected to a drive system (4).
- the drive system (4) is connected to the data bus (3).
- the positioning of the individual drives (7a-d) in relation to the folder (12) and relative to one another is regulated in the drive system (4).
- the data and commands coming from the higher-level control system (1) are adapted in the drive system (4) to the form required for the drive controllers (6a-d).
- Global control via the data bus (3) can therefore be limited to specifying setpoints, setpoint deviations and actual values, as well as setpoint control.
- the parameters for the fine adjustment of the individual drives (7a-d) are calculated separately in each pressure point group (2a-d) in the drive system (4).
- n drives and drive controllers (7a-d or 6a-d) there are m input / output units (9a-d). They are connected to a control system (10) via a control bus (8). This control system (10) is in turn connected to the data bus (3). The control system (10) coordinates the input / output units (9a-d) with each other and with the higher-level control system (1).
- responsibility is delegated from the higher-level control system to the largely autonomous pressure point groups. This means that the entire control system can be set up more simply and flexibly.
- FIG 3 finally shows schematically how the pressure point groups (2a-e) are assigned to a folder (12).

Abstract
Description
Die Erfindung bezieht sich auf das Gebiet der Drucktechnik. Sie betrifft insbesondere eine Rotationsdruckmaschine mit einzeln angetriebenen Zylindern.The invention relates to the field of printing technology. It relates in particular to a rotary printing press with individually driven cylinders.
Eine solche einzeln angetriebene Rotationsdruckmaschine ist auf den Seiten 78-80 der Zeitschrift "Zeitungstechnik" vom Dezember 1991 und in der Patentschrift DE-A-2 204 224 beschrieben.Such an individually driven rotary printing press is described on pages 78-80 of the magazine "Zeitungstechnik" from December 1991 and in the patent DE-A-2 204 224.
Bei einer einzeln angetriebenen Rotationsdruckmaschine fallen die mechanischen Wellenverbindungen (Längs- und Stehwellen) sowie die meisten Getriebe weg. Jeder Zylinder wird von einem separaten Motor direkt angetrieben.In the case of an individually driven rotary printing machine, the mechanical shaft connections (longitudinal and standing shafts) and most of the gears are eliminated. Each cylinder is driven directly by a separate engine.
Im oben genannten Artikel wird die technische Entwicklung auf dem Gebiet der direkt angetriebenen Rotationsdruckmaschinen dargelegt. Die Idee der längswellenfreien Rotationsdruckmaschine wurde schon Mitte der 60er Jahre von der schweizerischen Druckmaschinenfabrik Wifag erprobt. Der Versuch scheiterte jedoch daran, dass im unteren Drehzahlbereich kein stabiler Lauf erreicht wurde. Die hohen Genauigkeitsanforderungen konnten deshalb nicht befriedigt werden. Die Firma MAN Roland Druckmaschinen AG unternahm 1978 einen neuen Anlauf. Die Versuchsmaschine absolvierte alle Tests erfolgreich. Auch im Bezug auf die Genauigkeit konnten die Erfordernisse erfüllt werden. Die Genauigkeit der längswellenangetriebenen, konventionellen Rotationsdruckmaschinen wurde sogar noch übertroffen. Die Vorteile einer direkt angetriebenen Rotationsdruckmaschine sind vielfältig und umfassen:
- erhöhte Passergenauigkeit,
- präzisere Druckergebnisse durch Wegfall von Getriebespielen,
- kein Umfangregister mehr notwendig, da die Lage der Antriebe untereinander verschoben werden können,
- vereinfachte mechanische Konstruktion der Rotationsdruckmaschine,
- erleichterte Erweiterungsmöglichkeit der Maschine.
- increased register accuracy,
- more precise printing results by eliminating gear play,
- no more circumferential register necessary, since the position of the drives can be shifted among each other,
- simplified mechanical design of the rotary printing press,
- easier expansion of the machine.
Trotzdem konnte sich das Prinzip des Einzelantriebs nicht durchsetzten. Die Gründe dafür liegen in der Kompliziertheit der Regelung der einzelnen Antriebe, der Vernetzung des Leitsystems und der dadurch bedingten Störanfälligkeit und beschränkten Flexibilität des Aufbaus.Nevertheless, the principle of the single drive could not prevail. The reasons for this lie in the complexity of the control of the individual drives, the networking of the control system and the resulting susceptibility to faults and the limited flexibility of the structure.
Aufgabe der vorliegenden Erfindung ist es nun, eine direkt angetriebene Rotationsdruckmaschine anzugeben, welche die oben genannten Vorteile aufweist und die Nachteile der Kompliziertheit, Störanfälligkeit und der mangelnden Flexibilität des Leitsystems durch seinen speziellen Aufbau vermeidet.The object of the present invention is now to provide a directly driven rotary printing press which has the advantages mentioned above and avoids the disadvantages of the complexity, the susceptibility to faults and the lack of flexibility of the control system due to its special design.
Diese Aufgabe wird bei einer Rotationsdruckmaschine umfassend
- a) eine Anzahl einzeln angetriebener Zylinder, wobei die Antriebe mit Elektromotoren erfolgen und
- b) mindestens einen separat angetriebenen Falzapparat, dadurch gelöst, dass
- c) die Einzelantriebe der Zylinder und deren Antriebsregler zu Druckstellengruppen beliebig zusammengefasst werden,
- d) die Druckstellengruppen einem der Falzapparate zugeordnet sind und ihre Positionsreferenz von diesem Falzapparat beziehen, und
- e) die Verwaltung der Druckstellengruppen durch ein übergeordnetes Leitsystem erfolgt.
- a) a number of individually driven cylinders, the drives being carried out with electric motors and
- b) at least one separately driven folder, solved in that
- c) the individual drives of the cylinders and their drive controllers are combined into pressure point groups,
- d) the pressure point groups are assigned to one of the folders and obtain their position reference from this folder, and
- e) the management of the pressure point groups is carried out by a superordinate control system.
Durch die Zusammenfassung der Einzelantriebe und deren Antriebsregler zu beliebigen Druckstellengruppen und durch den Umstand, dass die Druckstellengruppen ihre Positionsreferenz vom Falzapparat beziehen, ergibt sich ein gesamtes Leitsystem, welches sich durch Einfachheit und Flexibilität auszeichnet.By combining the individual drives and their drive controllers into any pressure point groups and by the fact that the pressure point groups get their position reference from the folder, a complete control system results, which is characterized by simplicity and flexibility.
In einer ersten bevorzugten Ausführungsform wird die Rotationsdruckmaschine nach Anspruch 1 in einer Anordnung verwendet, die dadurch gekennzeichnet ist, dass
- a) die Einzelantriebe und deren Antriebsregler einer Druckstellengruppe über ein schnelles Bussystem, den Antriebsbus, verbunden sind;
- b) die Druckstellengruppen untereinander und mit einer Bedienungs- und Datenverarbeitungseinheit über einen Datenbus verbunden sind, und
- c) die Datenverarbeitungseinheit die Druckstellengruppen verwaltet, wobei
- d) diese Verwaltung die Vorgabe von Sollwerten und Sollwertabweichungen und die Verarbeitung von Istwerten umfasst sowie die Sollwertführung der verschiedenen Druckstellengruppen untereinander und zum Falzapparat koordiniert;
- e) der mindestens eine Falzapparat über den Datenbus mit den Druckstellengruppen verbunden ist.
- a) the individual drives and their drive controllers of a pressure point group are connected via a fast bus system, the drive bus;
- b) the pressure point groups are connected to one another and to an operating and data processing unit via a data bus, and
- c) the data processing unit manages the pressure point groups, wherein
- d) this administration includes the specification of target values and target value deviations and the processing of actual values, and coordinates the target value management of the various printing point groups with one another and with the folder;
- e) the at least one folder is connected to the printing point groups via the data bus.
Der Vorteil des erfindungsgemässen Aufbaus besteht darin, dass das gesamte Leitsystem der Rotationsdruckmaschine durch die Zusammenfassung der Einzelantriebe zu beliebigen Druckstellengruppen über ein schnelles Bussystem sehr einfach und störungsunanfällig wird. Die einzelnen Druckstellengruppen sind voneinander unabhängig und beziehen ihre Positionsreferenz von dem ihnen zugeordneten Falzapparat. Die Verwaltung der Druckstellengruppen erfolgt über ein übergeordnetes Leitsystem und umfasst nur noch die Vorgabe von Sollwerten und Sollwertabweichungen sowie die Verarbeitung von Istwerten.The advantage of the structure according to the invention is that the entire control system of the rotary printing press becomes very simple and susceptible to faults by combining the individual drives into arbitrary printing point groups via a fast bus system. The individual printing point groups are independent of each other and obtain their position reference from the folder assigned to them. The management of the pressure point groups takes place via a higher-level control system and only includes the specification of setpoints and setpoint deviations as well as the processing of actual values.
Das gesamte Leitsystem einer direkt angetriebenen Rotationsdruckmaschine wird nämlich deshalb so kompliziert, weil die Zylinder bei einer Zylinderumfangsgeschwindigkeit von 13 m/s auf 0.05 mm genau positioniert werden müssen. An die Daten-Uebertragungsgeschwindigkeit des verbindenden Bussystems werden in gleichem Masse sehr hohe Anforderungen gestellt. Erst die erfindungsgemässe Aufteilung des gesamten Leitsystems in Antriebsgruppen, deren Bestandteile über ein schnelles Bussystem verbunden sind, für die zeitkritische Regelung und ein übergeordnetes Leitsystem, welches problemlos eine kleinere Daten-Uebertragungsgeschwindigkeit aufweisen darf, für die zeitunkritischen Aufgaben wie die Vorgabe von Sollwerten und Sollwertabweichungen sowie die Verarbeitung von Istwerten, erlaubt trotz der hohen Genauigkeitsanforderungen einen einfachen und robusten Aufbau.The entire control system of a directly driven rotary printing press is so complicated because the cylinders have to be positioned with an accuracy of 0.05 mm at a cylinder peripheral speed of 13 m / s. The data transmission speed of the connecting bus system is subject to the same high demands. Only the inventive division of the entire control system into drive groups, the components of which are connected via a fast bus system, for the time-critical control and a higher-level control system, which may easily have a lower data transmission speed, for the non-time-critical tasks such as the specification of setpoints and setpoint deviations and The processing of actual values allows a simple and robust structure despite the high accuracy requirements.
Da die einzelnen Druckstellengruppen ihre Referenz vom zugeordneten Falzapparat beziehen und die Position der gesamten Gruppe in Relation zum Falzapparat verschoben werden kann, ist kein Hauptregister mehr notwendig. Ein weiterer Vorteil der erfindungsgemässen Anordnung liegt darin, dass die Maschine flexibel konfiguriert werden kann, da keine Rücksicht auf mechanische Verbindungen genommen werden muss. Das ganze Leitsystem ist also nicht total vernetzt, sondern weist klare Schnittstellen auf. Dadurch ist es auch unempfindlich gegenüber Störungen z.B. eines Einzelantriebes, da solche nur eine einzelne Druckstellengruppe betreffen.Since the individual printing point groups get their reference from the assigned folder and the position of the the entire group can be moved in relation to the folder, a main register is no longer necessary. Another advantage of the arrangement according to the invention is that the machine can be flexibly configured, since there is no need to take mechanical connections into account. The entire control system is therefore not totally networked, but has clear interfaces. As a result, it is also insensitive to malfunctions, for example of an individual drive, since these only affect a single pressure point group.
Kern der Erfindung ist es also, eine direkt angetriebene Rotationsdruckmaschine anzugeben, die sich durch Einfachheit und Robustheit des Leitsystems auszeichnet. Dies wird dadurch erreicht, dass das gesamte Leitsystem aufgeteilt wird in autonome Druckstellengruppen und ein übergeordnetes Leitsystem. Die Einzelantriebe der Zylinder und deren Antriebsregler innerhalb einer Druckstellengruppe sind über ein schnelles Bussystem, angepasst an die zeitkritischen Aufgaben, verbunden. Die Druckstellengruppen sind untereinander und mit dem übergeordneten Leitsystem über ein übergeordnetes Bussystem verbunden. Dieses Bussystem kann eine kleinere Daten-Uebertragungsgeschwindigkeit aufweisen, da es nur zeitunkritischen Aufgaben zu bewältigen hat. Die Druckstellengruppen beziehen ihre Positionsreferenz direkt vom zugeteilten Falzapparat. Die relative Lage der Zylinder einer Druckstellengruppe zueinander wird dabei unabhängig vom übergeordneten Leitsystem über das schnelle Bussystem eingestellt. Die einzelnen Druckstellengruppen weisen während dem Betrieb also ein hohes Mass an Autonomie auf.The essence of the invention is therefore to provide a directly driven rotary printing press which is characterized by the simplicity and robustness of the control system. This is achieved by dividing the entire control system into autonomous pressure point groups and a higher-level control system. The individual drives of the cylinders and their drive controllers within a pressure point group are connected via a fast bus system, adapted to the time-critical tasks. The pressure point groups are connected to each other and to the higher-level control system via a higher-level bus system. This bus system can have a lower data transmission speed, since it only has to deal with non-time-critical tasks. The printing point groups get their position reference directly from the assigned folder. The relative position of the cylinders of a pressure point group to each other is set independently of the higher-level control system via the fast bus system. The individual pressure point groups therefore have a high degree of autonomy during operation.
Durch die erwähnte Aufteilung des gesamten Leitsystems in ein übergeordnetes Leitsystem und autonome Druckstellengruppen, weist das gesamte Leitsystem dasjenige Mass an Einfachheit, Flexibilität und Robustheit gegenüber Störungen auf, welches für die Realisierung einer direkt angetriebenen Rotationsdruckmaschine notwendig ist.Due to the aforementioned division of the entire control system into a higher-level control system and autonomous pressure point groups, the entire control system has one The degree of simplicity, flexibility and robustness against malfunctions, which is necessary for the implementation of a directly driven rotary printing press.
Aus der Gesamtheit der abhängigen Ansprüche ergeben sich weitere vorteilhafte Ausführungsformen.Further advantageous embodiments result from the totality of the dependent claims.

Die in den Zeichnungen verwendeten Bezugszeichen und deren Bedeutung sind in der Bezeichnungsliste zusammengefasst aufgelistet. Grundsätzlich sind in den Figuren gleiche Teile mit gleichen Bezugszeichen versehen.The reference symbols used in the drawings and their meaning are summarized in the list of designations. In principle, the same parts are provided with the same reference symbols in the figures.
Bei einer einzeln angetriebenen oder längswellenfreien Rotationsdruckmaschine wir jeder Zylinder, insbesondere die Druck- und Gegendruckzylinder sowie der Falzapparat von einem eigenen Elektromotor angetrieben. Dadurch fallen die mechanischen Verbindungen weg. Die Einzelantriebe müssen natürlich aufeinander abgestimmt werden. Aufgrund der hohen Anforderungen an die Positioniergenauigkeit muss das verbindende Bussystem eine grosse Daten-Uebertragungsgeschwindigkeit aufweisen. Der naheliegendste Ansatz, alle Antriebe mit einer einzigen übergeordneten Zentraleinheit zu regeln, scheitert an der Kompliziertheit und an der beschränkten Flexibilität. Bei der erfindungsgemässen Rotationsdruckmaschine wird nun von einem ganz anderen Ansatz ausgegangen. Dies soll im Zusammenhang mit den Figuren erläutert werden.In the case of an individually driven or longitudinal shaft-free rotary printing press, each cylinder, in particular the impression and impression cylinders and the folder, are driven by their own electric motor. This eliminates the mechanical connections. The individual drives must of course be coordinated with each other. Due to the high demands on the positioning accuracy, the connecting bus system must have a high data transmission speed. The most obvious approach to regulating all drives with a single higher-level central unit fails because of the complexity and the limited flexibility. A completely different approach is now assumed for the rotary printing press according to the invention. This will be explained in connection with the figures.
Figur 1 zeigt ein Blockdiagramm einer erfindungsgemässen Rotationsdruckmaschine. Sie weist k Druckstellengruppen (2a-d) auf, welche über einen Datenbus (3) sowohl mit der Bedienungs- und Datenverarbeitungseinheit (1) als auch mit dem Falzapparat (12) verbunden sind. Die Einzelantriebe der Zylinder und deren Antriebsregler werden zu Druckstellengruppen (2a-d) zusammengefasst. Nur noch diese Druckstellengruppen (2a-d) stehen mit der Bedienungs- und Datenverarbeitungseinheit, d.h. mit dem übergeordneten Leitsystem (1) in Verbindung. Ihre Positionsreferenz beziehen die Druckstellengruppen direkt vom Falzapparat (12). Sie weisen also ein hohes Mass an Autonomie auf. FIG. 1 shows a block diagram of a rotary printing press according to the invention. It has k pressure point groups (2a-d) which are connected via a data bus (3) both to the operating and data processing unit (1) and to the folder (12). The individual drives of the cylinders and their drive controllers are combined into pressure point groups (2a-d). Only these pressure point groups (2a-d) are connected to the operating and data processing unit, ie to the higher-level control system (1). The printing point groups obtain their position reference directly from the folder (12). So you have a high degree of autonomy.
Figur 2 zeigt ein Blockdiagramm einer einzelnen Druckstellengruppe (2). Es sind n Einzelantriebe (7a-d) und dazugehörige n Antriebsregler (6a-d) vorhanden. Die Antriebsregler (6a-d) sind über ein schnelles Bussystem, den Antriebsbus (5) mit einem Antriebssystem (4) verbunden. Das Antriebssystem (4) steht mit dem Datenbus (3) in Verbindung. Im Antriebssystem (4) wird die Positionierung der Einzelantriebe (7a-d) in Relation zum Falzapparat (12) sowie relativ zueinander geregelt. Zusätzlich wird im Antriebssystem (4) die Anpassung der vom übergeordneten Leitsystem (1) kommenden Daten und Befehle an die für die Antriebsregler (6a-d) benötigte Form vorgenommen. Die globale Regelung über den Datenbus (3) kann sich also auf eine Vorgabe von Sollwerten, Sollwertabweichungen und Istwerten sowie die Sollwertführung beschränken. Die Berechnung der Parameter für die Feinjustierung der Einzelantriebe (7a-d) wird in jeder Druckstellengruppe (2a-d) separat im Antriebssystem (4) vorgenommen. FIG. 2 shows a block diagram of an individual pressure point group (2). There are n individual drives (7a-d) and associated n drive controllers (6a-d). The drive controllers (6a-d) are via a fast bus system Drive bus (5) connected to a drive system (4). The drive system (4) is connected to the data bus (3). The positioning of the individual drives (7a-d) in relation to the folder (12) and relative to one another is regulated in the drive system (4). In addition, the data and commands coming from the higher-level control system (1) are adapted in the drive system (4) to the form required for the drive controllers (6a-d). Global control via the data bus (3) can therefore be limited to specifying setpoints, setpoint deviations and actual values, as well as setpoint control. The parameters for the fine adjustment of the individual drives (7a-d) are calculated separately in each pressure point group (2a-d) in the drive system (4).
Neben den n Antrieben und Antriebsreglern (7a-d bzw. 6a-d) sind m Ein-/Ausgabeeinheiten (9a-d) vorhanden. Sie sind über einen Steuerbus (8) mit einem Steuersystem (10) verbunden. Dieses Steuersystem (10) steht wiederum mit dem Datenbus (3) in Verbindung. Das Steuersystem (10) koordiniert die Ein-/Ausgabeeinheiten (9a-d) untereinander und mit dem übergeordneten Leitsystem (1). Auch hier wird wieder deutlich wie, bildlich gesprochen, die Verantwortung vom übergeordneten Leitsystem auf die zu einem grossen Grad autonomen Druckstellengruppen delegiert wird. Dadurch kann das gesamte Leitsystem einfacher und flexibler aufgebaut werden.In addition to the n drives and drive controllers (7a-d or 6a-d), there are m input / output units (9a-d). They are connected to a control system (10) via a control bus (8). This control system (10) is in turn connected to the data bus (3). The control system (10) coordinates the input / output units (9a-d) with each other and with the higher-level control system (1). Here, too, it becomes clear how, figuratively speaking, responsibility is delegated from the higher-level control system to the largely autonomous pressure point groups. This means that the entire control system can be set up more simply and flexibly.
Figur 3 schliesslich zeigt schematisch, wie die Druckstellengruppen (2a-e) auf einen Falzapparat (12) zugeordnet werden. Selbstverständlich können auch mehrere Falzapparate (12) vorhanden sein und die Druckstellengruppen (2a-e) verschiedenen Falzapparaten (12) zugeordnet werden. Der Einfachheit halber wird in Figur 3 jedoch die Situation mit nur einem Falzapparat (12) dargestellt. Der Falzapparat (12) wird wie die Zylinder der Druckstellengruppen (2a-e) einzeln mit einem separaten Falzapparat-Antrieb (13) angetrieben. Die einzelnen Druckstellengruppen (2a-e) beziehen ihr Papier von den Papier-Abrollungen (11a-f). Die bedruckte Papierbahn wird im Falzapparat (12) geschnitten und gefaltet und z.B. zu kompletten Zeitungen zusammengefasst. Vorzugsweise bilden diejenigen Einzelantriebe der Zylinder eine Druckstellengruppe (2a-d), welche auf eine gemeinsame Papierbahn zuordnungsbar sind. Mit den Einzelantrieben der Zylinder können aber auch Untergruppen gebildet werden, sodass eine Druckstellengruppe (2e) mehrere, z.B. zwei, Papierbahnen gleichzeitig bedrucken kann. Figure 3 finally shows schematically how the pressure point groups (2a-e) are assigned to a folder (12). Of course, there can also be a plurality of folders (12) and the printing point groups (2a-e) can be assigned to different folders (12). For the sake of simplicity, however, the situation is shown in FIG shown with only one folder (12). The folder (12), like the cylinders of the pressure point groups (2a-e), is driven individually with a separate folder drive (13). The individual pressure point groups (2a-e) obtain their paper from the paper unwinds (11a-f). The printed paper web is cut and folded in the folder (12) and, for example, combined into complete newspapers. Those individual drives of the cylinders preferably form a pressure point group (2a-d) which can be assigned to a common paper web. With the individual drives of the cylinders, however, sub-groups can also be formed, so that one printing point group (2e) can print several, for example two, paper webs at the same time.
Abschliessend kann gesagt werden, dass sich die erfindungsgemässe, direkt angetriebene Rotationsdruckmaschine wegen der Auftrennung des gesamten Leitsystems in ein übergeordnetes Leitsystem und autonome Druckstellengruppen durch Einfachheit und Flexibilität auszeichnet und damit die Anforderungen erfüllt, welche für den wirtschaftlichen Betrieb einer direkt angetriebenen Rotationsdruckmaschine nötig sind.In conclusion, it can be said that the direct-driven rotary printing press according to the invention is characterized by simplicity and flexibility due to the separation of the entire control system into a higher-level control system and autonomous printing point groups and thus fulfills the requirements which are necessary for the economical operation of a directly-driven rotary printing press.
