Description

Die Erfindung betrifft ein System zum Bedrucken von Bedruckstoffbahnen.The invention relates to a system for printing substrate webs.

Zum Bedrucken von Bedruckstoffbahnen sind verschiedene Systeme bekannt, die nach unterschiedlichen Druckprinzipien arbeiten. Die vorliegende Erfindung bezieht sich auf solche Systeme, die nach dem Tiefdruckprinzip arbeiten.For printing substrate webs various systems are known which operate according to different printing principles. The present invention relates to such systems which operate on the gravure principle.

Bei diesem Druckprinzip werden meist mit einer metallischen Oberfläche versehene Druckzylinder eingesetzt, in die das Druckmotiv eingearbeitet ist. In der heutigen Zeit werden dazu mittels Laserstrahlen Vertiefungen, die später die Farbe transportieren, in die Oberflächen der Zylinder eingebracht. Diese Zylinder werden als Formzylinder bezeichnet.In this printing principle usually provided with a metallic surface pressure cylinder are used, in which the print motif is incorporated. At the present time, by means of laser beams, depressions, which later transport the paint, are introduced into the surfaces of the cylinders. These cylinders are called form cylinders.

Beim Druckvorgang tauchen diese Formzylinder in eine Farbwanne ein und nehmen so die auf den Bedruckstoff aufzutragende Farbe auf. Die Farbe auf den nicht bildgebenden Bereichen des Zylinders wird dabei von einer Rakelvorrichtung abgenommen. Der Bedruckstoff, welcher auf einer als Presseur bezeichneten Gegenlage läuft, nimmt die Farbe dann direkt von dem Formzylinder ab. In der Regel sind in einer Tiefdruckmaschine mehrere einzelne Tiefdruckwerke vorgesehen, um einen Mehrfarbendruck zu ermöglichen.During the printing process, these forme cylinders dip into a paint tray and thus absorb the ink to be applied to the substrate. The color on the non-imaging areas of the cylinder is removed by a squeegee device. The printing material, which runs on a designated as impression roller counter, then takes the color directly from the forme cylinder. In general, a plurality of individual gravure printing units are provided in a gravure printing machine to allow multi-color printing.

Ist nach der Abarbeitung eines Druckauftrages das Druckmotiv zu wechseln, so ist es aus der Patentanmeldung DE 100 21 398 A1 bekannt, den Formzylinder, welcher sich während des Druckvorgangs auf Lagerrollen abstützt, in radialer Richtung aus dem Tiefdruckwerk zu entnehmen. Das Maschinengestell des Tiefdruckwerks weist dazu entsprechende Ausnehmungen auf. Auf umgekehrtem Wege kann dem Druckwerk ein neuer Formzylinder zugeführt werden.If the print motif is to be changed after the execution of a print job, then it is from the patent application DE 100 21 398 A1 known, the form cylinder, which is supported during the printing operation on bearing rollers in the radial Direction to be taken from the gravure printing unit. The machine frame of the gravure printing unit has corresponding recesses. In the opposite way, the printing unit, a new form cylinder can be supplied.

Da derartige Formzylinder, die als Ganzes für verschiedene Druckaufträge vorgehalten werden, sehr teuer sind, hat es in der jüngeren Vergangenheit Tendenzen gegeben, die Formzylinder mehrteilig auszuführen und die einzelnen Bestandteile leicht trennbar zu gestalten. So bestehen solche Formzylinder oft aus einem Zylinderdorn, auf die eine Zylinderhülse aufbringbar ist, wobei letztere das eigentliche Druckmotiv trägt. Daher brauchen für die verschiedenen Druckmotive nur noch die Zylinderhülsen vorgehalten zu werden, während ein Zylinderdorn für verschiedene Druckaufträge herangezogen werden kann. Zylinderhülsen und Zylinderdorne müssen vor dem Rüsten des Tiefdruckwerks zu einem Formzylinder montiert werden, um in das Tiefdruckwerk eingebracht werden zu können.Since such form cylinder, which are kept as a whole for different print jobs are very expensive, there have been tendencies in the recent past to make the form cylinder in several parts and to make the individual components easily separable. So such form cylinder often consist of a cylinder mandrel on which a cylinder sleeve can be applied, the latter carries the actual print motif. Therefore, only the cylinder sleeves need to be maintained for the various print motifs, while a cylinder mandrel can be used for various print jobs. Cylinder sleeves and cylinder mandrels must be mounted before the gravure unit is set up to form a forme cylinder in order to be able to be introduced into the gravure printing unit.

Die Dokumente EP 0 485 913 A und US 3 098 433 A sind auch Teil des Standes der Technik.The documents EP 0 485 913 A and US 3,098,433 A are also part of the state of the art.

Die Aufgabe der vorliegenden Erfindung ist es, ein System vorzuschlagen, bei dem der Motivwechsel einfacher durchführbar ist.The object of the present invention is to propose a system in which the motif change is easier to carry out.

Die Aufgabe wird gelöst durch die Merkmale des Anspruchs 1.The object is solved by the features of claim 1.

Demnach umfasst ein erfindungsgemäßes System zumindest einen Formzylinder mit endseitigen Lagerzapfen, der in radialer Richtung in das Tiefdruckwerk eingesetzt werden kann. Weiterhin umfasst das System aber auch zumindest einen Zylinderdorn, der anstelle des Formzylinders in das Druckwerk eingebracht werden kann. Auf diesen in dem Druckwerk befindlichen Dorn sind dann verschiedene Zylinderhülsen in axialer Richtung des Zylinderdornes aufbringbar, ohne dass der Zylinderdorn aus dem Druckwerk entnommen werden muss. Damit kann also durch einfaches Austauschen der Zylinderhülsen das Druckmotiv geändert werden, oder wahlweise, wenn das Druckmotiv in einen Formzylinder mit endseitigen Lagerzapfen eingebracht ist, durch das Ersetzen des Formzylinders oder des Zylinderdorns durch den neuen Formzylinder. Auf diese Weise bietet das Druckwerk die Möglichkeit, den Motivwechsel so einfach wie möglich zu gestalten, wobei die Möglichkeit gegeben ist, bekannte Formzylinder, die oft über Jahre hinweg für wiederkehrende Druckaufträge vorgehalten werden, weiterhin einzusetzen. Der Formzylinder oder der anstelle dessen in das Druckwerk eingebrachte Zylinderdorn sind dabei mit einem Antrieb des Tiefdruckwerks drehfest verbindbar, so dass der Antrieb das zur Rotation notwendige Drehmoment auf die Zylinder übertragen kann. Der Antrieb, der also als Drehantrieb für den Formzylinder oder den Zylinderdorn dient, umfasst dabei einen Rotor und einen Stator, wobei die Zylinder mit dem Rotor drehfest verbunden sind und der Stator sich über eine geeignete Drehmomentstütze beispielsweise an zumindest einem Seitengestell des Tiefdruckwerks abstützt. Mit der vorliegenden Erfindung wird auch die Möglichkeit geschaffen, die Tiefdruckmaschine flexibel einzusetzen. Für qualitativ hochwertige Produkte werden häufig herkömmliche Formzylinder verwendet, die in der Regel eine hohe Festigkeit aufweisen. Für Produkte, die möglichst kostengünstig hergestellt werden sollen, bitten sich Zylinderdorne mit Zylinderhülsen. Beide Zylinderarten können erfindungsgemäß in einem Tiefdruckwerk eingesetzt werden. Dieses Tiefdruckwerk ist entsprechend hinsichtlich seiner technischen Eigenschaften ausgestaltet, wie im Folgenden ausgeführt wird.Accordingly, a system according to the invention comprises at least one forme cylinder with end bearing journals which can be inserted into the gravure printing unit in the radial direction. Furthermore, the system also includes at least one cylinder mandrel, which can be introduced into the printing unit instead of the forme cylinder. On this located in the printing unit mandrel then various cylinder sleeves in the axial direction of the cylinder mandrel can be applied without the cylinder mandrel has to be removed from the printing unit. Thus, therefore, the print motif can be changed by simply replacing the cylinder sleeves, or optionally, when the print motif is introduced into a forme cylinder with end journal, by replacing the forme cylinder or cylinder mandrel with the new forme cylinder. In this way, the printing unit offers the opportunity to To make motif changes as easy as possible, with the possibility of using known form cylinder, which are often kept for years for recurring print jobs continue to use. The forme cylinder or the cylinder mandrel instead inserted in the printing unit are rotatably connected to a drive of the gravure printing unit, so that the drive can transmit the torque required for rotation to the cylinders. The drive, which thus serves as a rotary drive for the forme cylinder or the cylinder mandrel, in this case comprises a rotor and a stator, wherein the cylinders are rotatably connected to the rotor and the stator is supported via a suitable torque arm, for example on at least one side frame of the gravure printing unit. With the present invention, the possibility is created to use the gravure printing machine flexible. For high-quality products often conventional form cylinder are used, which usually have a high strength. For products that are to be produced as inexpensively as possible, ask cylinder mandrels with cylinder sleeves. Both types of cylinders can be used according to the invention in a gravure printing unit. This gravure printing unit is designed accordingly in terms of its technical properties, as will be explained below.

Vorteilhaft ist es dabei, wenn der Antrieb des Tiefdruckwerks in axialer Richtung des betreffenden Zylinders verschiebbar ist. Dazu kann der Stator auf Schienen geführt sein, welche mit dem Seitengestell verbunden sein können. Der Rotor, der über geeignete Drehlager im oder am Stator drehbar, aber axial unverschieblich gelagert ist, ist über eine geeignete Kupplung mit den Zapfen des Formzylinders oder des Zylinderdornes verbunden. Zum Austausch des Formzylinders oder des Zylinderdornes muss also nur die Kupplung gelöst werden und der Antrieb so weit in axialer Richtung verschoben werden, bis der Zapfen des Zylinders frei liegt, so dass der Formzylinder oder der Zylinderdorn in radialer Richtung aus dem Druckwerk entnommen werden kann. Alternativ kann der Rotor axial innerhalb des Stators verschiebbar sein. Der Stator muss dann nicht verschiebbar sein, sondern kann fest, beispielsweise mit dem Tiefdruckwerksgestell, verbunden sein. Zum An- bzw. Abkoppeln des Formzylinders oder des Zylinderdorns braucht nun lediglich der Rotor verschoben zu werden.It is advantageous if the drive of the gravure printing unit in the axial direction of the cylinder in question is displaced. For this purpose, the stator may be guided on rails, which may be connected to the side frame. The rotor, which is rotatably mounted on suitable rotors in or on the stator, but axially immovable, is connected via a suitable coupling with the pins of the forme cylinder or the cylinder mandrel. To replace the forme cylinder or the cylinder mandrel so only the coupling must be solved and the drive so far be moved in the axial direction until the pin of the cylinder is exposed, so that the forme cylinder or the cylinder mandrel can be removed in the radial direction from the printing unit. Alternatively, the rotor may be axially displaceable within the stator. The stator then does not have to be displaceable, but can be fixed, for example connected to the gravure printing unit frame. To connect or disconnect the Form cylinder or the cylinder mandrel now only needs the rotor to be moved.

Auf dem dem Antrieb gegenüber liegenden Ende des Formzylinders oder des Zylinderdorns kann in einer vorteilhaften Ausführungsform ein Abfanglager angeordnet sein, welches ebenfalls in axialer Richtung verschiebbar ist. Mit diesem auf einen Lagerzapfen aufschiebbares und ein Drehlager umfassendes Abfanglager kann der Zylinder während des Druckvorganges unterstützt werden. Dieses Abfanglager kann zudem in radialer Richtung des Zylinders verschoben oder verschwenkt werden, um ein axiales Abziehen der Zylinderhülse von dem Zylinderdorn zu ermöglichen.On the drive opposite end of the forme cylinder or the cylinder mandrel can be arranged in an advantageous embodiment, an interceptor, which is also displaced in the axial direction. With this can be pushed onto a journal and a pivot bearing comprehensive intercepting the cylinder can be supported during the printing process. This interceptor can also be moved or pivoted in the radial direction of the cylinder to allow an axial withdrawal of the cylinder sleeve of the cylinder mandrel.

In einer vorteilhaften Ausführungsform der Erfindung sind Haltemittel vorgesehen, die den Formzylinder oder den Zylinderdorn in einer Position halten, in der seine Achse mit den Achsen des Abfanglagers und/oder des Antriebs fluchtet, wenn Abfanglager und/oder Antrieb noch nicht oder nicht mehr in Kontakt mit dem Formzylinder oder dem Zylinderdorn stehen oder den Formzylinder oder den Zylinderdorn noch nicht oder nicht mehr fest halten. Dies ist insbesondere der Fall, wenn eine Transportvorrichtung den betreffenden Zylinder an das Druckwerk zur Montage übergibt oder kurz bevor die Transportvorrichtung den Zylinder übernimmt. Selbstverständlich kann die Übergabe- oder Übernahmeposition sich von der mit dem Abfanglager oder dem Antrieb fluchtenden Position unterscheiden. Wichtig ist dann, dass die Haltemittel den Zylinder in eine fluchtende Position verbringen können. Als fluchtende Position wird diejenige Position verstanden, in der die Drehachsen des Antriebs, speziell die Drehachse des Rotors, mit der Drehachse des Formzylinders oder des Zylinderdorns fluchtet.In an advantageous embodiment of the invention holding means are provided which hold the forme cylinder or the cylinder mandrel in a position in which its axis is aligned with the axes of the interceptor and / or the drive, if interceptor and / or drive is not or no longer in contact stand with the forme cylinder or the cylinder mandrel or not hold the form cylinder or the cylinder mandrel or no longer firm. This is particularly the case when a transport device transfers the cylinder in question to the printing unit for assembly or just before the transport device takes over the cylinder. Of course, the transfer or transfer position may differ from the position aligned with the interceptor or drive. It is important then that the holding means can spend the cylinder in an aligned position. The aligned position is that position in which the axes of rotation of the drive, especially the axis of rotation of the rotor, are aligned with the axis of rotation of the forme cylinder or the cylinder mandrel.

Weitere Ausführungsbeispiele der Erfindung gehen aus der gegenständlichen Beschreibung und den Ansprüchen hervor.Further embodiments of the invention will become apparent from the description and the claims.

Die Figuren 1 a und 1 b zeigen einen Formzylinder 2, welcher zum Zweck der Montage in dem Druckwerk 1 gehalten wird. Der Formzylinder 2 umfasst dabei einen zylindrischen Druckbereich 3, in dessen metallische Oberfläche das Druckmotiv eingraviert ist. Über eine oder mehrere Ringstufen geht der Formzylinder 2 in Lagerzapfen 4 und 5 über. Die Lagerzapfen 4 und 5 ragen seitlich über die Seitengestellwände 6 und 7 des Druckwerks 1 hinaus, welches aus diesem Grunde über schlitzartige Einkerbungen 8 verfügt, so dass der Formzylinder 2 in radialer Richtung, die durch den Doppelpfeil R angedeutet ist, in das Druckwerk 1 eingeführt werden kann. Die in die Seitengestellwand 7 eingebrachte Einkerbung 8 ist größer dimensioniert als die in der Seitengestellwand 6. Das Einführen des Formzylinders 2 oder auch des Zylinderdorns kann mittels einer geeigneten Transport- und/oder Transfereinrichtung erfolgen, mit welcher der Formzylinder 2 oder der Zylinderdorn zum Tiefdruckwerk transportiert werden kann und/oder der Zylinder 2 oder der Dorn dem Druckwerk zugeführt werden kann. Ist der Formzylinder in Richtung R in das Tiefdruckwerk eingeführt worden, so kann im Bereich der Enden des Formzylinders je ein Haltearm 9 in Kontakt mit dem Formzylinder gebracht werden. Jeder Haltearm 9 wird dazu von unten an den den Formzylinder heran gebracht. Ist dies erfolgt, kann die Transport- und/oder Transfereinrichtung den Formzylinder freigeben, da er nun von den Haltearmen gehalten wird.The FIGS. 1 a and 1b show a form cylinder 2, which is held in the printing unit 1 for the purpose of assembly. The forme cylinder 2 in this case comprises a cylindrical pressure region 3, in the metallic surface of which the print motif is engraved. About one or more ring stages of the forme cylinder 2 in bearing pins 4 and 5 goes over. The journals 4 and 5 protrude laterally beyond the side frame walls 6 and 7 of the printing unit 1, which for this reason has slot-like notches 8, so that the forme cylinder 2 in the radial direction, which is indicated by the double arrow R, can be introduced into the printing unit 1. The introduced into the side frame wall 7 notch 8 is dimensioned larger than that in the side frame wall 6. The insertion of the forme cylinder 2 or the cylinder mandrel can be done by means of a suitable transport and / or transfer device with which the forme cylinder 2 or the cylinder mandrel transported to the gravure printing unit can be and / or the cylinder 2 or the mandrel can be supplied to the printing unit. If the forme cylinder has been introduced in the direction of R in the gravure printing unit, so each holding arm 9 can be brought into contact with the forme cylinder in the region of the ends of the forme cylinder. Each support arm 9 is brought zoom from below to the forme cylinder. If this is done, the transport and / or transfer device can release the form cylinder, since it is now held by the holding arms.

In der in der Fig. 1a dargestellten Situation wird der Formzylinder 2 durch die als Haltearme 9 ausgebildeten Haltemittel in dem Druckwerk 1 gehalten, wobei die Achsen des Formzylinders 2, des in dem Lagergehäuse 10 befindlichen Drehlagers 11 und des Antriebs 12 fluchten. Die Haltearme 9 weisen Vertiefungen 13 auf, in die Abschnitte des Formzylinders 2 eingelegt sind, so dass dieser nicht von den Haltearmen 9 herunterrollen kann. Zu diesem Zweck sind auch Festlegehebel 14 vorgesehen, die ebenfalls Vertiefungen 15 aufweisen. Die Haltearme 9 und die Festlegehebel 14 sind in dem dargestellten Ausführungsbeispiel um an den Seitengestellwänden 6 und 7 angreifenden Drehpunkte schwenkbar gelagert. Die Haltearme 9 und Festlegehebel 14 können jedoch grundsätzlich an anderen Bauteilen des Druckwerks 1 angebracht sein oder sogar an einer nicht mit dem Druckwerk in Verbindung stehenden Einrichtung. So ist es denkbar, dass die nicht gezeigte, aber oben erwähnte Transport- und/oder Transfereinrichtung Halteelemente wie etwa Haltearme 9 und Festlegehebel 14 umfasst. Im Rahmen der Erfindung ist zudem eine andere Bewegungsmöglichkeit der Haltearme un der Festlegehebel abgesehen von dem Schwenkbewegung denkbar. So ist eine einfach, laterale Verfahrmöglichkeit denkbar.In the in the Fig. 1a illustrated situation, the forme cylinder 2 is held in the printing unit 1 by the holding means formed as a holding arms 9, wherein the axes of the forme cylinder 2, located in the bearing housing 10 pivot bearing 11 and the drive 12 are aligned. The holding arms 9 have recesses 13, in which portions of the forme cylinder 2 are inserted, so that it can not roll down from the support arms 9. For this purpose, locking lever 14 are also provided, which also have recesses 15. The retaining arms 9 and the locking lever 14 are pivotally mounted in the illustrated embodiment by pivot points acting on the side frame walls 6 and 7. However, the retaining arms 9 and locking lever 14 may in principle be attached to other components of the printing unit 1 or even on a device not connected to the printing unit. Thus, it is conceivable that the transport and / or transfer device not shown, but mentioned above holding elements such as holding arms 9 and locking lever 14 includes. In the context of the invention, another possibility for movement of the retaining arms and the locking lever is also conceivable apart from the pivoting movement. So a simple, lateral Verfahrmöglichkeit is conceivable.

Je ein Haltearm 9 und ein Festlegehebel 14 werden von einem Antrieb verschwenkt. Ein solcher Antrieb, der in den Figuren als Kolbenzylindereinheit 17 dargestellt ist, wirkt auf nicht näher dargestellte Weise auf die vorgenannten Bauteile. Die Bewegung eines Haltearms 9 und des ihm zugeordneten Festlegehebels 14 können durch geeignete Mittel, etwa getriebliche Mittel, miteinander gekoppelt sein, um ein gleichmäßiges Erfassen des Formzylinders zu ermöglichen.Depending on a holding arm 9 and a locking lever 14 are pivoted by a drive. Such a drive, which is shown in the figures as a piston-cylinder unit 17, acts in a manner not shown on the aforementioned components. The movement of a support arm 9 and its associated locking lever 14 may be coupled to each other by suitable means, such as gear means, to allow a uniform detection of the forme cylinder.

Die Haltearme 9 und die Festlegehebel 14 sind an den einander zugewandten Seiten der Seitengestellwände angelenkt, aber derartig positioniert, dass sie den Formzylinder außerhalb des druckempfindlichen Druckbereichs 3 erfassen. Zumindest eine Kombination aus einem Haltearm 9 und einem Festlegehebel 14 ist so dimensioniert, dass sie dem Kippmoment des Formzylinders dauerhaft entgegenwirken, wenn dieser nur von einer Haltearm-/Festlegehebel-Kombination und dem am gleichen Seitenwandgestell angeordneten Antrieb oder Lager gehalten wird.The holding arms 9 and the fixing levers 14 are hinged to the mutually facing sides of the side frame walls, but positioned so as to grip the form cylinder outside the pressure-sensitive printing area 3. At least one combination of a retaining arm 9 and a locking lever 14 is dimensioned so that they permanently counteract the tilting moment of the forme cylinder when it is held only by a Haltearm- / Festlegehebel combination and arranged on the same side wall frame drive or bearing.

In der in der Fig. 1 a dargestellten Situation brauchen nur noch das Lager 11 und der Antrieb 12 axial in Richtung auf die Lagerzapfen 4 und 5 aufgeschoben zu werden.In the in the Fig. 1 a situation shown only need the bearing 11 and the drive 12 to be pushed axially in the direction of the bearing pins 4 and 5.

Nach dem Aufschieben des Lagers 11 und des Antriebs können die Haltearme 9 und die Festlegemittel 14 von dem Formzylinder gelöst und entfernt werden. Nun wird der Druckvorgang ermöglicht. Diese Situation ist in den Figuren 2a und 2b dargestellt.After pushing the bearing 11 and the drive, the retaining arms 9 and the fixing means 14 can be released from the forme cylinder and removed. Now the printing is possible. This situation is in the FIGS. 2a and 2b shown.

Die Figuren 3a und 3b zeigen eine den Figuren 1 a und 1 b analoge Situation, in der jedoch statt eines Formzylinder ein Zylinderdorn 18 in das Druckwerk verbracht wurde. Der Zylinderdorn 18 wird von den bereits oben beschriebenen Haltearmen 9 und Festlegehebel 14 gehalten. Im Unterschied zur in der Fig. 1 a dargestellten Situation ist nun das Lagergehäuse 10 nicht nur in axialer Richtung, sondern auch in radialer Richtung bewegt worden. Auf diese Weise gibt das Lagergehäuse den Weg frei, um die Druckzylinderhülse 19 nachträglich auf den Zylinderdorn 18 aufschieben zu können. Es ist selbstverständlich möglich, den Zylinderdorn bereits mit einer Hülse auszustatten, welche für den ersten Druckauftrag in das Druckwerk eingesetzt benötigt wird. Zur Montage der Hülse 19 bei einem bereit in das Druckwerk eingebrachten Dorn sind jedoch weitere Schritte notwendig, die anhand der Figuren 4a und 4b erläutert werden.The FIGS. 3a and 3b show a den FIGS. 1 a and 1 b analogous situation in which, however, instead of a forme cylinder, a cylinder mandrel 18 has been spent in the printing unit. The cylinder mandrel 18 is held by the retaining arms 9 and locking lever 14 already described above. Unlike in the Fig. 1 a situation shown, the bearing housing 10 has now been moved not only in the axial direction, but also in the radial direction. In this way, the bearing housing clears the way to the pressure cylinder sleeve 19th subsequently be able to postpone on the cylinder mandrel 18. It is of course possible to equip the cylinder mandrel already with a sleeve which is needed for the first print job used in the printing unit. For mounting the sleeve 19 in a ready introduced into the printing unit mandrel, however, further steps are necessary, based on the FIGS. 4a and 4b be explained.

In den Figuren 4a und 4b ist zu erkennen, dass der Antrieb 12 bereits auf den Lagerzapfen 4 aufgeschoben und an diesen angekuppelt wurde. Danach können die Haltearme 9 und die Festlegehebel 14 von dem Zylinderdorn 18 gelöst werden, so dass die Zylinderhülse 19 durch die Seitengestellwand 7 hindurch auf den Zylinderdorn 18 aufgeschoben werden kann. Zwischen der Innenoberfläche der Zylinderhülse 19 und der Außenoberfläche des Zylinderdorns 18 kann Druckluft eingeblasen werden, die den Zylinderdorn zur Verringerung der Reibungskräfte leicht dehnt. Der Rotor des Antriebs 12 stützt sich dabei mit mindestens zwei Drehlagern an dem Stator bzw. dem Antriebsgehäuse ab, damit durch den in dieser Situation nur einendig gehaltenen Zylinderdorn verursachten Hebelkräfte abgefangen werden können. Alternativ dazu kann auch im Prinzip der dem Seitengestell 6 zugeordnete Haltearm 9 den Zylinderdorn 18 halten. In diesem Fall kommt der Antriebsmotor auch mit einem einzigen Drehlager aus.In the FIGS. 4a and 4b It can be seen that the drive 12 has already been pushed onto the bearing journal 4 and coupled to this. Thereafter, the retaining arms 9 and the locking lever 14 can be released from the cylinder mandrel 18, so that the cylinder sleeve 19 can be pushed through the side frame wall 7 on the cylinder mandrel 18. Between the inner surface of the cylinder sleeve 19 and the outer surface of the cylinder mandrel 18 compressed air can be injected, which easily stretches the cylinder mandrel to reduce the frictional forces. The rotor of the drive 12 is supported with at least two pivot bearings on the stator or the drive housing, so that can be intercepted by the lever in this situation only one-end held cylinder mandrel leverage. Alternatively, in principle, the support arm 9 associated with the side frame 6 can hold the cylinder mandrel 18. In this case, the drive motor also comes with a single pivot bearing.

Die Figuren 5a und 5b zeigen den Zylinderdorn 18 mit vollständig aufgeschobener Zylinderhülse 19. Der Bereich des Zylinderdorns 18, welcher die Zylinderhülse 19 aufnimmt, wird im Folgenden als Hülsenaufnahmeabschnitt 20 bezeichnet. Der Zylinderdorn 18 kann mit so genannten Dehnspannhülsen ausgestattet sein, die ein Festlegen der Zylinderhülse auf dem Dorn 18 ermöglichen. In der dargestellten Situation haben der der Seitengestellwand 7 zugeordnete Haltearm 9 und der Festlegehebel 14 wieder das dem Abfanglager 11 zugewandte Ende des Zylinderdorns 18 erfasst und dieses so weit angehoben, dass die Achse des Dorns 18 wieder mit der Achse des Lagers 11 fluchtet. Dieser Schritt ist notwendig, da es sich nicht vermeiden lässt, dass sich der nur einendig gehaltene Dorn 18 an seinem freien Ende ein wenig absenkt. Der Haltearm 9 ist also in der Lage, das entsprechende Ende des Zylinderdorns 18 wieder anzuheben. Auch das Lagergehäuse 10 wurde wieder radial bewegt, so dass die Achsen des Zylinderdorns 18 und des Lagers 11 wieder fluchten. Danach kann das Lagergehäuse wieder axial verschoben werden, so dass das Lager 11 den Lagerzapfen 5 umfasst und der Haltearm 9 und Festlegehebel 14 entfernt werden. Diese dadurch entstandene Situation ist in den Figuren 6a und 6b dargestellt. Der Zylinder, bestehend aus Dorn 18 und Hülse 19, ist nun druckbereit.The FIGS. 5a and 5b show the cylinder mandrel 18 with the cylinder sleeve 19 fully pushed in. The region of the cylinder mandrel 18 which receives the cylinder sleeve 19 is referred to below as the sleeve receiving portion 20. The cylinder mandrel 18 may be equipped with so-called Dehnspannhülsen that allow fixing the cylinder sleeve on the mandrel 18. In the illustrated situation of the side frame wall 7 associated holding arm 9 and the locking lever 14 again the scavenger 11 facing end of the cylinder mandrel 18 has detected and this raised so far that the axis of the mandrel 18 is aligned with the axis of the bearing 11 again. This step is necessary because it can not be avoided that the only one-end held mandrel 18 lowers a little at its free end. The holding arm 9 is thus able to raise the corresponding end of the cylinder mandrel 18 again. The bearing housing 10 was again moved radially, so that the axes of the cylinder mandrel 18 and the bearing 11 are aligned again. Thereafter, the bearing housing can be moved axially again, so that the bearing 11 comprises the bearing pin 5 and the retaining arm 9 and locking lever 14 are removed. This resulting situation is in the Figures 6a and 6b shown. The cylinder, consisting of mandrel 18 and sleeve 19, is now ready to print.

Die Figuren 7a, 7b und 7c zeigen ein in axialer und radialer Richtung verschobenes Lagergehäuse 10. Die der Seitengestellwand 6 zugeordnete Haltearm 9 und Festlegehebel 14 sind soweit zusammengefahren, dass zwischen ihnen noch ein Abstand verbleibt, der größer als der Außendurchmesser des Zylinderaufnahmeabschnitts 20 ist, aber kleiner als der Außendurchmesser der Zylinderhülse 19 (siehe Figur 7c). Auf diese Weise werden Haltearm 9 und Festlegehebel 14 in die Bereiche der Stirnseite 21 der Zylinderhülse 21 gefahren. Wird nun der Antrieb 12 in axialer Richtung A verschoben, ohne dass der Lagerzapfen 4 abgekoppelt wird, wird der Zylinderdorn 18 ein Stück weit aus der Hülse 19 herausgezogen, die durch den Haltearm 9 und den Festlegehebel 14 in ihrer Position verbleibt. Diese Situation ist in der Fig. 8 dargestellt. Der Haltearm 9 und der Festlegehebel sind dazu mit Dämpfungsstücken 22 belegt, die eine Beschädigung der Zylinderhülse 19 vermeiden. Wenn nun der Antrieb 12 wieder in die entgegen gesetzte Richtung verschoben wird, gelangt der Zylinderdorn 18 wieder in seine Ausgangsstellung zurück, die Zylinderhülse 19 ist jedoch gegenüber der Ausgangsstellung zur Seitengestellwand 7 verschoben (siehe Figur 9). In dieser Position kann die Hülse nun vom Bedienpersonal ergriffen und in axialer Richtung aus dem Druckwerk entfernt werden (Figur 10).

The side frame wall 6 associated holding arm 9 and locking lever 14 are moved together so far that between them still leaves a distance which is greater than the outer diameter of the cylinder receiving portion 20, but smaller than the outer diameter of the cylinder sleeve 19 (see FIG. 7c ). In this way, holding arm 9 and locking lever 14 are moved into the areas of the end face 21 of the cylinder sleeve 21. Now, if the drive 12 is moved in the axial direction A, without the bearing pin 4 is decoupled, the cylinder mandrel 18 is pulled a little way from the sleeve 19, which remains in position by the support arm 9 and the locking lever 14. This situation is in the Fig. 8 shown. The retaining arm 9 and the locking lever are assigned to this with damping pieces 22, which avoid damage to the cylinder sleeve 19. Now, if the drive 12 is moved back in the opposite direction, the cylinder mandrel 18 returns to its original position, the cylinder sleeve 19, however, relative to the starting position to the side frame wall 7 is moved (see FIG. 9 ). In this position, the sleeve can now be grasped by the operator and removed in the axial direction of the printing unit ( FIG. 10 ).
