Abstract

The invention relates to a process and a facility for the operation of a single-color or multi-color printing facility. A first, uniformly designed, idle time occasioning movable machine group of at least one machine unit is used substantially constantly for printing operation. It interacts along a congruent separating line (T), common to all colors, with a second, idle time occasioning machine group of the machine unit, which, for a new run, is exchanged for a further idle time occasioning machine group. The stationary machine groups can be designed differently for the passage of divided or continuous printing material. The separating line runs between plate cylinders of the movable machine group and rubber blanket cylinders of the stationary machine group, which can be components of a rotary sheet-fed or reel-fed printing press. The stationary machine groups are connected by a transport device to a turning device for receiving the movable machine groups. This makes a substantially continuous operation possible for the printing of finite or continuous printing material.

Description

Die Erfindung betrifft eine Rotations-Druckeinrichtung der Satellitenbauart für Flach- und indirekten Hochdruck.The invention relates to a rotary printing device of the satellite type for flat and indirect high pressure.

Der Betrieb konventioneller Druckmaschinen, gleichgültig, ob Ein- oder Mehrfarbenmaschinen, setzt den Stillstand solcher Maschinen bei ihrer Aufrüstung zur Druckbereitschaft, wie Farbwechsel, Druckplattenwechsel, Reinigen usw. voraus, weil die Maschinen eine in sich geschlossene Einheit bilden. Während dieser Stillstände sind daher diese Maschinen unproduktiv, d.h., sie verursachen Totzeiten. Besonders zeitraubend können diese Vorgänge dann sein, wenn aus Gründen der Zugänglichkeit, z.B. zu einem Plattenzylinder, Teilaggregate, wie z.B. das Farbwerk oder Teile davon, innerhalb der Maschine verschoben oder gekippt werden müssen. Naturgemäß multipliziert sich bei Mehrfarben-Druckmaschinen der Zeitaufwand und Personalbedarf.The operation of conventional printing machines, regardless of whether single or multi-color machines, requires the standstill of such machines when they are ready for printing, such as color changes, printing plate changes, cleaning, etc., because the machines form a self-contained unit. During these downtimes, these machines are therefore unproductive, i.e. they cause dead times. These processes can be particularly time-consuming if, for reasons of accessibility, e.g. to a plate cylinder, subassemblies, e.g. the inking unit or parts thereof must be moved or tilted within the machine. Naturally, the time and manpower required for multi-color presses is multiplied.

Bei sehr kleinen Druckeinrichtungen, wie z.B. Etikettenlinien, hat man versucht, dieses Problem der "Totzeiten" dadurch zu lösen, daß man einzelne Elemente kassettenartig austauschen kann. Dies ist bei den an solche Maschinen gestellten Qualitätsansprüchen möglich, wegen der Vielzahl solcher kleiner Elemente aber wiederum zeitaufwendig.With very small printing devices, e.g. Label lines, one has tried to solve this problem of "dead times" in that individual elements can be exchanged like a cassette. This is possible with the quality requirements placed on such machines, but again time-consuming because of the large number of such small elements.

So ist in der DE-A-2 025 676 ein Farbwerk zur Einfärbung einer Druckplatte auf dem Druckzylinder einer Druckmaschine beschrieben, bei dem eine Mehrzahl von Walzen einen Farbweg von einem Farbspender zu einem Druckzylinder bilden. Die Walzen und der Farbspender sind dabei in einem austauschbaren Kassettengehäuse angeordnet. Das Kassettengehäuse besteht aus einem Übertragungsteil, das an der Außenseite des Gehäuses angebracht ist und Antriebskräfte von der Druckmaschine aufnimmt, sowie aus einer Vorrichtung zur Verbindung dieses Übertragungsteiles mit mindestens einer der Walzen in dem Kassettengehäuse. Diese Anordnung bezweckt, die Lagerung und Reinigung des Farbverteilers zu erleichtern und einen schnellen Wechsel der Farbe zu ermöglichen.DE-A-2 025 676, for example, describes an inking unit for inking a printing plate on the printing cylinder of a printing press, in which a plurality of rollers form an ink path from an ink dispenser to a printing cylinder. The rollers and the ink dispenser are arranged in an exchangeable cassette housing. The cassette housing consists of a transmission part which is attached to the outside of the housing and receives drive forces from the printing press, and of a device for connecting this transmission part to at least one of the rollers in the cassette housing. The purpose of this arrangement is to facilitate the storage and cleaning of the paint distributor and to enable a quick change of color.

Aus der DE-B-1 169 959 ist eine als Reihenmaschine ausgebildete Mehrfarben-Bogenrotationsdruckmaschine bekannt, bei der eine Druckwerkseinheit durch zwei einem Druckzylinder zugeordnete, etwa übereinander angeordnete Plattenzylinder und diesen zugeordnete Farbwerke gebildet ist, wobei die beiden Farbwerke in einem gemeinsamen Rahmen auf Schrägbahnen von den Plattenzylindern wegbewegbar sind. Dieser Konstruktion liegt der Gedanke zugrunde, daß es bei Dreizylinderdruckwerken für Zweifarbenhochdruck vorteilhaft ist, die beiden Farbwerke, wie an sich bekannt, gemeinsam abfahrbar zu lagern und sie dabei außerdem in steiler Bahn ähnlich hochfahrbar anzuordnen, wie es bei Schnellpressen für das von ihrer ebenen Druckform abfahrbare Farbwerk bekannt ist. Dadurch wird der Abstand zwischen dem Formzylinderpaar und einer Druckwerkseinheit und dem nächsten Aggregat, einer weiteren Druckwerkseinheit oder einem Großstapelausleger so verkürzt, daß der entsprechende Raum abwechselnd entweder nur für das Doppelfarbwerk in seiner Arbeitsstellung ausreicht oder in der Ausfahrstellung des schräg hochfahrbaren Doppelfarbwerkes den erforderlichen Bedienungsraum für die Plattenzylinder als üblichen, vom Fußboden aus betretbaren Querdurchgang der Maschine bildet. Auf diese Weise soll der sonst übliche besondere Bedienungsraum hinter jeder Druckeinheit eingespart werden, während der besteigbare Querdurchgang der Maschine erst bei schräg hochgefahrenem Doppelfarbwerk entsteht, weil der Raum zwischen den Plattenzylindern und dem nächsten Aggregat im Betriebszustand durch das eingefahrene Farbwerk ausgefüllt ist.From DE-B-1 169 959 a multi-color sheet-fed rotary printing press designed as a series machine is known, in which a printing unit is formed by two plate cylinders assigned to one another, approximately one above the other, and inking units assigned to them, the two inking units in a common frame on inclined paths are movable away from the plate cylinders. This construction is based on the idea that it is advantageous in three-cylinder printing units for two-color letterpress printing to store the two inking units together, as is known per se, in such a way that they can be moved down and, in addition, to arrange them on a steep path in a similar manner to that which can be achieved in high-speed presses for their flat printing form removable inking unit is known. This shortens the distance between the pair of forme cylinders and a printing unit and the next unit, a further printing unit or a large stack delivery, so that the corresponding space alternately either suffices only for the double inking unit in its working position or in the extended position of the double inking unit, which can be raised at an angle, the necessary operating space for forms the plate cylinder as a normal cross passage of the machine that can be entered from the floor. In this way, the otherwise usual special operating space behind each printing unit is to be saved, while the mountable cross passage of the machine is only created when the double inking unit is raised at an angle, because the space between the plate cylinders and the next unit is filled in by the retracted inking unit in the operating state.

Trotz der oben zum Stand der Technik angeführten Entwicklungen ist es bisher nicht gelungen, beim Betrieb von Druckeinrichtungen die Rüstzeiten aus der Produktionszeit weitestgehend zu eliminieren. Dieser Nachteil wirkt sich insbesondere bei Satellitenmaschinen aus, die im Vergleich zu den Reihenmaschinen wesentlich kompakter, aber entsprechend schwieriger zugänglich sind. Darüber hinaus ist bei den genannten Druckeinrichtungen keine Möglichkeit vorgesehen, sie auf das Bedrucken unterschiedlichster Bedruckstoffe, wie Papier, Karton und Blech in Form von Tafeln, Bogen, Rollen oder Etiketten umzustellen.Despite the developments in the state of the art mentioned above, it has so far not been possible to largely eliminate the set-up times from the production time when operating printing devices. This disadvantage has a particular effect on satellite machines, which are considerably more compact than the in-line machines, but are correspondingly more difficult to access. In addition, no possibility is provided for the printing devices mentioned to convert them to printing on a wide variety of printing materials, such as paper, cardboard and sheet metal, in the form of sheets, sheets, rolls or labels.

Der Erfindung liegt daher die Aufgabe zugrunde, sämtliche Totzeiten verursachende Arbeiten abgelöst von einer ständig betriebsbereiten stationären Maschinengruppe durchführen und gleichzeitig die Einsatzmöglichkeit für das Bedrucken praktisch sämtlicher Arten von Bedruckstoffen ermöglichen zu können.The invention is therefore based on the object of carrying out all the work that causes dead times, detached from a permanently operational stationary machine group and, at the same time, being able to enable the use for printing on virtually all types of substrates.

Die Erfindung löst diese Aufgabe durch die Kombination der im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale.The invention solves this problem by combining the features listed in the characterizing part of patent claim 1.

Eine derart ausgestaltete Rotations-Druckeinrichtung der Satellitenbauart für Flach- und indirekten Hochdruck ermöglicht einerseits eine selbständige Funktionsfähigkeit der stationären und der beweglichen Maschinengruppe sowie die unmittelbare Zugänglichkeit der Plattenzylinder mit den zugehörigen Farb- und Feuchtwerken einerseits sowie andererseits der Gummituchzylinder und des Gegendruckzylinders. Durch die senkrecht verlaufende Trennfuge zwischen der stationären Maschinengruppe und der beweglichen Maschinengruppe wird eine optimale Trennung und Zugänglichkeit der in der beweglichen Maschinengruppe befindlichen, Totzeiten verursachenden Aggregate von den ständig produktionsbereiten Aggregaten in der stationären Maschinengruppe erreicht. Durch die Transportvorrichtung für die beweglichen Maschinengruppen, die mit einer Wendevorrichtung zur gleichzeitigen Aufnahme von mindestens zwei Maschinengruppen vorgesehen ist, können zwei bewegliche, Totzeiten verursachende Maschinengruppen gleichzeitig mit den beiden stationären Maschinengruppen verbunden und für die Produktion eingesetzt werden, so daß eine dritte bewegliche, Totzeiten verursachende Maschinengruppe nach ihrer Wartung oder Reinigung nicht bis zur erneuten Auswechslung mit der soeben ausgetauschten bewegelichen Maschinengruppe mit dem Arbeitseinsatz warten muß, sondern gegen eine von zwei beweglichen Maschinengruppen ausgewechselt werden kann. Infolgedessen ist eine optimale Ausnutzung der Produktionskapazität der Einrichtung sowie eine Einsparung an Totzeiten der Ersatz-Maschinengruppe möglich. Da die Trennfuge sowohl für als Rotations-Bogendruckmaschine ausgebildete bewegliche Maschinengruppen als auch für als Rotations-Rollenmaschine ausgebildete bewegliche Maschinengruppen gleich ist, wird eine bisher nicht erreichbare Vielseitigkeit der erfindungsgemäßen Druckeinheit erreicht, ohne daß die beweglichen Maschinengruppen einer Umstellung bedürfen, um sie an das Bedrucken von Bogen oder Rollen anzupassen.Such a rotary printing device of the satellite type for flat and indirect high pressure enables on the one hand an independent functionality of the stationary and the moving machine group as well as the direct accessibility of the plate cylinders with the associated inking and dampening units on the one hand and on the other hand the rubber blanket cylinder and the impression cylinder. The vertical joint between the stationary machine group and the movable machine group ensures optimal separation and accessibility of the units in the movable machine group that cause dead times from the constantly production-ready units in the stationary machine group. Due to the transport device for the movable machine groups, which is provided with a turning device for the simultaneous reception of at least two machine groups, two movable machine groups which cause dead times can be connected to the two stationary machine groups at the same time and used for production, so that a third Movable machine groups causing dead times do not have to wait until they are replaced with the mobile machine group that has just been replaced with their work, but can be exchanged for one of two mobile machine groups. As a result, an optimal utilization of the production capacity of the device as well as a saving in dead times of the replacement machine group is possible. Since the parting line is the same both for movable machine groups designed as a rotary sheet-fed printing machine and for movable machine groups designed as a rotary web press, the versatility of the printing unit according to the invention, which has not been achieved to date, is achieved without the movable machine groups needing to be changed in order to adapt them to printing of sheets or rolls.

Nachstehend ist die Erfindung anhand der schematischen Darstellung eines Ausführungsbeispiels näher beschrieben. Es zeigen:

  • Fig. 1 eine Ansicht der stationären Maschinengruppen einer Bogen-Rotationsdruckmaschine und einer Rollen-Rotationsdruckmaschine mit drei auswechselbaren, identischen, Totzeiten verursachenden Maschinengruppen und
  • Fig. 2 eine Draufsicht eines Teils der Wendevorrichtung in Fig. 1.
The invention is described in more detail below on the basis of the schematic illustration of an exemplary embodiment. Show it:
  • Fig. 1 is a view of the stationary machine groups of a sheet-fed rotary printing press and a web-fed rotary printing press with three interchangeable, identical machine groups and causing dead times
  • FIG. 2 shows a top view of a part of the turning device in FIG. 1.

Bogen- und Rollen-Rotationsdruckmaschine der Satelliten-Bauart ausgebildet ist. Die Bogen-Rotationsdruckmaschine besteht aus einer stationären, permanent betriebsbereiten Maschinengruppe 1 und zwei identischen, beweglichen, Totzeiten verursachenden Maschinengruppen 2a, 2c. Die bewegliche Maschinengruppe 2a ist mit der stationären Maschinengruppe 1a betriebsbereit verbunden, wobei die Maschinengruppen 1a und 2a eine für alle Farben gemeinsame kongruente Trennfuge T bilden, die im wesentlichen senkrecht verläuft.Sheet and roll rotary printing machine of the satellite type is designed. The sheet-fed rotary printing press consists of a stationary, permanently operational machine group 1 and two identical, movable machine groups 2a, 2c which cause dead times. The movable machine group 2a is operatively connected to the stationary machine group 1a, the machine groups 1a and 2a forming a congruent parting line T which is common to all colors and runs essentially perpendicular.

Die stationäre Maschinengruppe 1a besteht aus einem Gegendruckzylinder, mit dem ein Antriebsritzel kämmt, das über einen Kettentrieb und ein Getriebe mit einem Antriebsmotor verbunden ist.The stationary machine group 1a consists of an impression cylinder with which a drive pinion meshes, which is connected to a drive motor via a chain drive and a transmission.

Der stationären Maschinengruppe 1a sind ferner eine Anlage 9 und eine Auslage 10 für den bogen- oder tafelförmigen Bedruckstoff an der der beweglichen Maschinengruppe 2a abgekehrten Seite zugeordnet. An der der beweglichen Maschinengruppe 2a zugekehrten Seite des Gegendruckzylinders sind vier Gummituchzylinder angeordnet, die über etwa eine Hälfte des Umfangs des Gegendruckzylinders an diesem anliegen. Die Gummituchzylinder sind in einem Maschinenrahmen der stationären Maschinengruppe 1a drehbar gelagert und weisen einen wesentlich geringeren Durchmesser als der Gegendruckzylinder auf. Es ist somit ersichtlich, daß die stationäre Maschinengruppe 1 ständig betriebsbereit ist.The stationary machine group 1a is also assigned a system 9 and a delivery 10 for the sheet or sheet-shaped printing material on the side facing away from the movable machine group 2a. On the side of the impression cylinder facing the movable machine group 2a, four blanket cylinders are arranged which rest on the impression cylinder over about half of the circumference thereof. The blanket cylinders are rotatably mounted in a machine frame of the stationary machine group 1a and have a much smaller diameter than the impression cylinder. It can thus be seen that the stationary machine group 1 is always ready for operation.

In dem Maschinenrahmen 3a der beweglichen Maschinengruppe 2a sind entlang der Trennfuge T vier Plattenzylinder 13 drehbar gelagert, die zu jedem Druck gefeuchtet und eingefärbt werden. Die Plattenzylinder 13 bringen die Farbe mit einem Teil der Feuchtigkeit spiegelverkehrt auf die Gummituchzylinder auf, welche die Farbe an den Bedruckstoff weitergeben und ebenfalls entlang der Trennfuge T angeordnet sind.In the machine frame 3a of the movable machine group 2a, four plate cylinders 13 are rotatably mounted along the parting line T, which are moistened and colored at every pressure. The plate cylinders 13 apply the ink with some of the moisture in a mirror-inverted manner to the blanket cylinders, which pass on the ink to the printing material and are likewise arranged along the parting line T.

Den Plattenzylindern 13 in der beweglichen Maschinengruppe 2a sind zu diesem Zweck jeweils ein Farbwerk und ein Feuchtwerk mit einem Farbkasten bzw. Feuchtkasten und einer Vielzahl von Farb- und Feuchtwalzen zugeordnet.For this purpose, the plate cylinders 13 in the movable machine group 2a are each assigned an inking unit and a dampening unit with an inking unit or dampening unit and a multiplicity of inking and dampening rollers.

Infolge der zwischen den Plattenzylindern 13 der beweglichen Maschinengruppe 2a und den Gummituchzylindern der stationären Maschinengruppe 1a im wesentlichen senkrecht verlaufenden kongruenten Trennfuge T sind demnach die Plattenzylinder 13 sowie die dazugehörigen Farbwerke und Feuchtwerke 15, 15a ebenso wie die Gummituchzylinder und der Gegendruckzylinder unmittelbar für Wartungs- und Austauschzwecke zugänglich, wenn die bewegliche Maschinengruppe 2a von der stationaren Maschinengruppe 1a getrennt wird.As a result of the congruent parting line T running essentially vertically between the plate cylinders 13 of the movable machine group 2a and the rubber blanket cylinders of the stationary machine group 1a, the plate cylinders 13 and the associated inking units and dampening units 15, 15a as well as the rubber blanket cylinders and the impression cylinder are directly for maintenance and Exchange purposes accessible when the movable machine group 2a is separated from the stationary machine group 1a.

Die zwischen die Plattenzylinder 13 und die Gummituchzylinder gelegte Trennfuge T ermöglicht somit eine saubere Trennung zwischen den in der beweglichen Maschinengruppe 2a angeordneten, durch Personal zu wartenden Aggregaten und den in der stationären Maschinengruppe 1a angeordneten wartungsfreien Aggregaten, die, soweit sie einer Wartung bedürfen, automatisch gewartet, z.B. gewaschen bzw. gereinigt werden. Die Verlegung der Trennfuge T längs der Plattenzylinder 13 und Gummituchzylinder macht diese jeweils unmittelbar zugänglich und die ihnen zugehörigen Feucht- und Farbwerke für Austausch- oder Reinigungszwecke erreichbar.The parting line T placed between the plate cylinders 13 and the blanket cylinders thus enables a clean separation between the units arranged in the movable machine group 2a, to be serviced by personnel, and the maintenance-free units arranged in the stationary machine group 1a, which, insofar as they require maintenance, automatically serviced, e.g. be washed or cleaned. The laying of the parting line T along the plate cylinders 13 and blanket cylinders makes them directly accessible and the associated dampening and inking units can be reached for exchange or cleaning purposes.

Die bewegliche Maschinengruppe 2b ist mit der beweglichen Maschinengruppe 2a identisch, also ebenfalls mit vier Plattenzylindern 13 versehen, denen in gleicher Weise Farbwerke und Feuchtwerke zugeordnet sind.The movable machine group 2b is identical to the movable machine group 2a, that is also provided with four plate cylinders 13, to which inking units and dampening units are assigned in the same way.

Gemäß Fig. 1 und 2 ist die bewegliche Maschinengruppe 2a mittels einer Transportvorrichtung 18 gegen die bewegliche Maschinengruppe 2c austauschbar, um den Stillstand der Produktion auf eine geringstmögliche Zeit zu begrenzen und die Rüstzeit für die ausgewechselte Maschinengruppe 2a zugunsten der Produktionszeit einsparen zu können. Zu diesem Zweck ist die bewegliche Maschinengruppe 2a auf Schienen 16 angeordnet, die zu einem Drehtisch 17 führen, auf dem die bewegliche Maschinengruppe 2c steht.1 and 2, the movable machine group 2a can be exchanged for the movable machine group 2c by means of a transport device 18 in order to limit the standstill of the production to the shortest possible time and to save the set-up time for the replaced machine group 2a in favor of the production time. For this purpose, the movable machine group 2a is arranged on rails 16 which lead to a turntable 17 on which the movable machine group 2c stands.

Parallel zu den Schienen 16 ist in senkrechter Ebene ein Kettentrieb 18a angeordnet, dessen Kette mit Mitnehmern 19 versehen ist, die in geeigneter Weise mit entsprechenden Kupplungselementen 20 der beweglichen Maschinengruppen 2a, 2c kuppelbar sind. Der Kettentrieb 18 ist durch ein Antriebssystem 21 antreibbar. Obwohl zwischen den Transportschienen 16 ein einziger Kettentrieb 18a für den Transport der beweglichen Maschinengruppen vorgesehen ist, kann auch jeweils im Bereich einer Schiene 16 je einer von zwei derartigen Kettentrieben 18a angeordnet sein. Die endlosen Transportketten der Kettentriebe 18a sind in üblicher Weise um Kettenzahnräder 22, 23 herumgeführt, von denen das Kettenzahnrad 23 in geeigneter Weise mit dem Antrieb 21 verbunden ist.In parallel to the rails 16, a chain drive 18a is arranged in the vertical plane, the chain of which is provided with drivers 19 which can be coupled in a suitable manner to corresponding coupling elements 20 of the movable machine groups 2a, 2c. The chain drive 18 can be driven by a drive system 21. Although a single chain drive 18a is provided between the transport rails 16 for the transport of the movable machine groups, one of two such chain drives 18a can also be arranged in the region of a rail 16 to be in order. The endless transport chains of the chain drives 18a are routed in a conventional manner around sprockets 22, 23, of which the sprocket 23 is connected to the drive 21 in a suitable manner.

Anstelle von Kettentrieben können andere mechanische oder auch hydraulische, pneumatische und elektrische Antriebe oder Kombinationen derselben verwendet werden.Instead of chain drives, other mechanical or hydraulic, pneumatic and electrical drives or combinations thereof can be used.

An dem der stationären Maschinengruppe 1a abgekehrten Ende der Transportvorrichtung 18 befindet sich der Drehtisch 17, der um eine senkrechte Achse 24 mittels eines Antriebs 25 drehbar ist. Die Antriebskräfte des Antriebs 25 auf den Drehtisch 17 können beispielsweise mittels eines Kettentriebs 26 übertragen werden.At the end of the transport device 18 facing away from the stationary machine group 1a there is the turntable 17, which can be rotated about a vertical axis 24 by means of a drive 25. The driving forces of the drive 25 on the turntable 17 can be transmitted, for example, by means of a chain drive 26.

Wie ersichtlich, ist der Drehtisch 17 so groß bemessen, daß auf ihm zumindest die beiden beweglichen Maschinengruppen 2a, 2b Platz finden. Infolgedessen kann im Rahmen eines feststehenden Arbeitszyklus die Maschinengruppe 2a mittels der Transportvorrichtung 18 auf den Schienen 16 zu dem Drehtisch 17 in die strichpunktiert dargestellte Stellung C befördert werden. Anschließend wird der Drehtisch mittels des Antriebs 25 um 180 Grad gedreht, damit eine Maschinengruppe 2c mittels der Transportvorrichtung 18 auf den Schienen 16 in die Betriebsstellung an der stationären Maschinengruppe 1a gefahren und mit dieser wiederum entlang der kongruenten Trennfuge T mechanisch gekuppelt werden kann. Infolgedessen nimmt die ausgewechselte Maschinengruppe 2a nunmehr die in Fig. 1 gezeigte Stellung der Maschinengruppe 2c ein und ist allseitig für Wartungsarbeiten zugänglich, während gleichzeitig die Bogen-Rotationsmaschine, die aus der stationären Maschinengruppe 1a und der beweglichen Maschinengruppe 2c besteht, praktisch ohne Unterbrechung weiter produzieren kann.As can be seen, the turntable 17 is dimensioned so large that at least the two movable machine groups 2a, 2b find space on it. As a result, the machine group 2a can be transported on the rails 16 to the turntable 17 in the position C shown in broken lines in the context of a fixed work cycle by means of the transport device 18. The turntable is then rotated by 180 degrees by means of the drive 25, so that a machine group 2c can be moved by means of the transport device 18 on the rails 16 into the operating position on the stationary machine group 1a and can be mechanically coupled to it along the congruent parting line T. As a result, the replaced machine group 2a now assumes the position of the machine group 2c shown in FIG. 1 and is accessible from all sides for maintenance work, while at the same time the sheet-fed rotary machine, which consists of the stationary machine group 1a and the movable machine group 2c, continues to produce practically without interruption can.

Gemäß der Erfindung ist vorgesehen, die Totzeiten zu verringern, die dadurch entstehen, daß die auf dem Drehtisch 17 befindliche bewegliche Maschinengruppe 2c auf ihren erneuten Austausch gegen die andere bewegliche Maschinengruppe 2a nach ihrer Wartung und Vorbereitung auf den nächsten Betriebseinsatz warten muß. Diese Wartezeit kann vermieden werden, wenn der Produktionszyklus so gestaltet wird, daß die gewartete und für den nächsten Produktionseinsatz vorbereitete bewegliche Maschinengruppe 2c einer weiteren stationären Maschinengruppe zugeführt und mit dieser für den gemeinsamen Betriebseinsatz verbunden werden kann.According to the invention, it is provided to reduce the dead times which result from the fact that the movable machine group 2c located on the turntable 17 has to wait for its renewed exchange with the other movable machine group 2a after its maintenance and preparation for the next operational use. This waiting time can be avoided if the production cycle is designed in such a way that the mobile machine group 2c, which has been serviced and prepared for the next production use, is fed to a further stationary machine group and can be connected to it for the common operational use.

Gemäß Fig. 1 und 2 ist diese Einsparung von Rüstzeiten dadurch vorgesehen, daß der stationären Maschinengruppe 1a der Bogen-Rotationsdruckmaschine im Abstand gegenüberliegend eine zweite, identische stationäre Maschinengruppe 27 einer Rollen-Rotationsdruckmaschine angeordnet ist. In der Mitte zwischen den beiden stationären Maschinengruppen 1a, 27 ist der Drehtisch 17 vorgesehen, zu dem jeweils zwei Kettentriebe 18a, 18b hinführen. Die beweglichen Maschinengruppen 2a, 2b sind zum Betriebseinsatz mit den stationären Maschinengruppen 1a, 27 entlang der gemeinsamen Trennfuge T verbunden, während die dritte bewegliche Maschinengruppe 2c auf dem Drehtisch 17 in einer gegenüber den beiden anderen Maschinengruppen 2a, 2b um 90 Grad gedrehten Stellung angeordnet ist und auf die Auswechslung mit einer der beiden anderen beweglichen Maschinengruppen 2a, 2b wartet.1 and 2, this saving of makeready times is provided in that a second, identical stationary machine group 27 of a web-fed rotary printing press is arranged at a distance opposite the stationary machine group 1 a of the sheet-fed rotary printing press. The turntable 17 is provided in the middle between the two stationary machine groups 1a, 27, to which two chain drives 18a, 18b each lead. The movable machine groups 2a, 2b are connected for operation with the stationary machine groups 1a, 27 along the common parting line T, while the third movable machine group 2c is arranged on the turntable 17 in a position rotated by 90 degrees with respect to the other two machine groups 2a, 2b and waits for replacement with one of the other two moving machine groups 2a, 2b.

Fig. 1 veranschaulicht, daß die beweglichen Maschinengruppen 2a, 2b nach Belieben mit der stationären Maschinengruppe 1a einer Bogen-Rotationsdruckmaschine oder der stationären Maschinengruppe 27 einer Rollen-Rotationsdruckmaschine betriebsmäßig verbunden werden können.Fig. 1 illustrates that the movable machine groups 2a, 2b can be operatively connected to the stationary machine group 1a of a sheet-fed rotary printing press or the stationary machine group 27 of a web-fed rotary printing press as desired.

Die stationäre Maschinengruppe 27 der Rollen-Rotationsdruckmaschine ist wie die stationäre Maschinengruppe 1a der Bogen-Rotationsdruckmaschine in Satelliten-Bauweise ausgeführt und weist einen Gegendruckzylinder 28 auf, um den herum vier Gummituchzylinder 29 angeordnet und in dem Maschinengestell 30 drehbar gelagert sind. In der Anlage ist mit 31 eine Rolle für den Bedruckstoff bezeichnet, der eine Ersatzrolle 32 vorgelagert ist. Der Bedruckstoff wird in der Auslage durch eine Trockenvorrichtung 33 wahlweise einer Rolle 34 oder einem Querschneider 35 und einer Planauslage 36 zugeführt. In diesem Zusammenhang ist es selbstverständlich denkbar, im rechten Winkel zu den hier dargestellten Maschineneinheiten einer Bogen-Rotationsdruckmaschine bzw. Rollen-Rotationsdruckmaschine, ausgehend vom Drehtisch 17, weitere stationäre Maschinengruppen für Bogen- und/oder Rollen-Rotationsdruck anzuordnen.The stationary machine group 27 of the web-fed rotary printing press, like the stationary machine group 1a of the sheet-fed rotary printing press, is designed in a satellite design and has an impression cylinder 28, around which four blanket cylinders 29 are arranged and rotatably mounted in the machine frame 30. In the system, 31 is a roller for the printing material, which is preceded by a replacement roller 32. The printing material is fed in the delivery through a drying device 33 either to a roller 34 or a cross cutter 35 and a flat delivery 36. In this context, it is of course conceivable to arrange further stationary machine groups for sheet and / or web rotary printing at right angles to the machine units of a sheet-fed rotary printing press or web-fed rotary printing press shown here, starting from the rotary table 17.

Aus der vorstehenden Beschreibung ergibt sich somit deutlich, daß die Erfindung eine optimale, weil praktisch kontinuierliche Ausnutzung der zur Verfügung stehenden kapazitäten von Bogen- und Rollen-Rotationsdruckmaschinen ermöglicht, wobei eine besonders vorteilhafte Lösung für Maschinen der Satelliten-Bauart gefunden wurde, deren Wartung im Hinblick auf die kompakte Anordnung ihrer einzelnen Aggregate unmöglich ist. Ferner können endliche und endlose Bedruckstoffe verschiedenster Materialien bedruckt werden, wie Papier oder Blech.From the above description it is clear that the invention enables an optimal, because practically continuous utilization of the available capacities of sheet and web rotary printing presses, a particularly advantageous solution for machines of the satellite type having been found in the maintenance In view of the compact arrangement of their individual units is impossible. Furthermore, finite and endless substrates can be printed on various materials, such as paper or sheet metal.
