Description

Die Erfindung bezieht sich auf eine Druckmaschine mit mindestens einem Formzylinder mit einer eine Druckform tragenden, auswechselbaren Hülse.The invention relates to a printing press with at least one forme cylinder with an interchangeable sleeve carrying a printing form.

Bei bekannten Flachdruckmaschinen, insbesondere Offset-Druckmaschinen, müssen, wenn das zu druckende Bild geändert werden soll, die Druckformen ausgewechselt werden. Dazu muß die gesamte Druckmaschine angehalten werden; der Wechsel der Druckformen geschieht in der Regel von Hand. Es sind aber auch automatische Umrüstsysteme bekannt (Robotik). Bei Formulardruckmaschinen werden Zylinder teilweise von Hand ausgewechselt. Bei Tiefdruckmaschinen ist der Zylinderwechsel mit Kränen ein gebräuchliches Verfahren.In known planographic printing machines, in particular offset printing machines, if the image to be printed is to be changed, the printing forms must be replaced. To do this, the entire printing press must be stopped; the change of printing forms is usually done by hand. However, automatic changeover systems are also known (robotics). On form printing machines, cylinders are partially replaced by hand. In gravure printing machines, changing cylinders with cranes is a common procedure.

Aus der US 5 186 103 ist eine Druckmaschine bekannt, die insbesondere zum Bedrucken einer Papierbahn aus schwerem oder hartem Kartonmaterial dient, und die austauschbare Zylinder aufweist. Da entsprechend den verschiedenen zu bedruckenden Verpackungsmaterialien die zu druckenden Bilder unterschiedliche Breiten und Längen haben, ist es notwendig, Formzylinder mit unterschiedlichen Durchmessern zu verwenden und aus zuwechseln. Dabei ist entweder nur der Formzylinder (beim Direktdruck) oder der Formzylinder zusammen mit dem Übertragungszylinder (beim Offsetdruck) in einer auswechselbaren Kassette angeordnet, die aus dem jeweiligen Druckwerksturm der Druckmaschine herausnehmbar ist. Zum Herausnehmen dient eine Förderwinde, die auf einer Schiene beweglich angeordnet ist. Sie zieht die Kassette zunächst nach oben und transportiert sie dann weg, um sie gegen eine andere Kassette mit einem Formzylinder oder einem Formzylinder in Verbindung mit einem Übertragungszylinder auszutauschen, der bzw. die einen anderen Durchmesser hat bzw. haben.A printing press is known from US Pat. No. 5,186,103 which is used in particular for printing on a paper web made of heavy or hard cardboard material and which has interchangeable cylinders. Since the images to be printed have different widths and lengths according to the different packaging materials to be printed, it is necessary to use and replace forme cylinders with different diameters. Either only the forme cylinder (for direct printing) or the forme cylinder together with the transfer cylinder (for offset printing) is arranged in an exchangeable cassette the respective printing tower of the printing press is removable. A winch, which is movably arranged on a rail, serves to remove it. It first pulls the cassette up and then transports it away to be exchanged for another cassette with a forme cylinder or a forme cylinder in connection with a transfer cylinder which has a different diameter.

Ein derartiges Wechselverfahren, das nicht nur das Herausnehmen eines einzigen Formzylinders, sondern darüber hinaus noch das Entfernen einer Kassette, die in der Seitenwand des jeweiligen Druckwerks befestigt ist, erfordert, ist sehr aufwendig. Es führt zu einem langen Stillstand der Maschine bei einem Wechsel der Formzylinder und dem damit verbundenen Wechsel der Druckformen. Durch den Stillstand einer Druckmaschine wird aber das Wasser-Farbe-Gleichgewicht in Farbwerk und Feuchtwerk der Druckmaschine empfindlich gestört und muß wieder neu eingestellt werden.Such a changing process, which requires not only the removal of a single forme cylinder, but also the removal of a cassette which is fastened in the side wall of the respective printing unit, is very complex. This leads to a long standstill of the machine when changing the forme cylinder and the associated change of printing forms. When a printing machine comes to a standstill, the water-ink balance in the inking unit and dampening unit of the printing machine is disturbed and must be readjusted.

Aus der CH 314 349 und der US 3 147 702 sind Druckmaschinen mit Mitteln zur umfangs- und seitenregisterrichtigen Lagerung der Formzylinder bekannt. Aus der EP 0 453 973 A1 ist eine Offset-Druckmaschine bekannt, in der bei Änderung des Formats der Druckform sowohl der Formzylinder als auch der Übertragungszylinder und der Druckzylinder jeweils gegen einen anderen Formzylinder, Übertragungszylinder bzw. Druckzylinder ausgewechselt werden. Die Zylinder werden mittels eines Wagens transportiert. Diese Maschine ist geeignet zum Austauschen eines eine Druckform in Form einer auf seinem Mantel kraftschlüssig haltenden Hülse tragenden Formzylinders und hat die Merkmale des Oberbegriffs des Anspruchs 1.From CH 314 349 and US Pat. No. 3,147,702, printing machines with means for storing the forme cylinders in the correct circumferential and lateral register are known. An offset printing machine is known from EP 0 453 973 A1, in which, when the format of the printing form is changed, both the forme cylinder and the transfer cylinder and the impression cylinder are each replaced by another forme cylinder, transfer cylinder or impression cylinder. The cylinders are transported by a cart. This machine is suitable for replacing a forme cylinder which carries a printing form in the form of a sleeve holding non-positively on its jacket and has the features of the preamble of claim 1.

Aus der WO 92/07716 ist eine Druckmaschine für den Direktdruck bekannt, deren Druckform von einer dünnen Folie gebildet wird. Die Druckfolie wird mittels einer Bebilderungseinrichtung innerhalb der Druckmaschine bebildert.A printing machine for direct printing is known from WO 92/07716, the printing form of which is formed by a thin film. The printing film is imaged within the printing machine by means of an imaging device.

Es ist die Aufgabe der vorliegenden Erfindung, eine Druckmaschine der eingangs genannten Art so zu verbessern, daß sich die Druckform auf dem Formzylinder leicht austauschen läßt.It is the object of the present invention to improve a printing press of the type mentioned at the outset so that the printing form on the forme cylinder can be easily replaced.

Diese Aufgabe wird, wie in Patentanspruch 1 angegeben, gelöst.This object is, as stated in claim 1, solved.

Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous further developments result from the subclaims.

Der Wechsel der Druckform kann auch durch einen Roboter geschehen. Besonders geeignet ist ein Formzylinder, der mit einer erneuerbaren Druckform bespannt ist. In der Zeit, in der der andere Formzylinder zum Drucken dient, läßt sich die verdruckte Druckform durch eine Löschvorrichtung löschen und anschließend neu bebildern. Dies geschieht beispielsweise durch ein Tintendruckverfahren oder durch ein Thermotransferverfahren mit einer Folie, die den Formzylinder bedeckt. Für die Erneuerung der Oberflache des Formzylinders steht damit genügend Zeit zur Verfügung. Dadurch, daß der Formzylinder aus der Druckmaschine ausgeladen und nicht in ihr selbst wieder bebildert wird, ergeben sich keine Platzprobleme für die Bebilderungseinheit.The printing form can also be changed by a robot. A form cylinder that is covered with a renewable printing form is particularly suitable. During the time in which the other forme cylinder is used for printing, the printed printing form can be deleted by an erasing device and then re-imaged. This is done for example by an ink printing process or by a thermal transfer process with a film that covers the forme cylinder. Sufficient time is therefore available for the renewal of the surface of the forme cylinder. The fact that the forme cylinder is unloaded from the printing press and is not imaged again in the printing press does not result in any space problems for the imaging unit.

Durch die Erfindung werden definierte Schnittstellen zwischen der Druckmaschine, d.h. der Lagerung des Formzylinders in den Seitenwänden der Druckmaschine, und dem Formzylinder selbst geschaffen. Um ihn umfangs und seitenregisterrichtig in der Druckmaschine zu lagern, sind beispielsweise in den Seitenwänden in Richtung der Längsachse des Formzylinders bewegliche Lagerpinolen für den Formzylinder, Formzylinderspanner und Stirnverzahnungen zwischen dem Zylinderlager und dem Formzylinder vorgesehen.The invention creates defined interfaces between the printing press, ie the mounting of the forme cylinder in the side walls of the printing press, and the forme cylinder itself. In order to store it correctly and circumferentially in the printing machine, bearing sleeves for the forme cylinder, forme cylinder tensioner and spur gears between the cylinder bearing and the forme cylinder are provided, for example, in the side walls in the direction of the longitudinal axis of the forme cylinder.

Das Ablagemagazin, das zum Auswechseln der Formzylinder dient, weist vorzugsweise einen Trommelspeicher auf, in dem einer oder mehrere Formzylinder zum Auswechseln gelagert wird bzw. werden. Die Greif-, Dreh- und Hubelemente, mit denen der Formzylinder aus der Druckmaschine herausgenommen wird und gegen einen anderen Formzylinder ausgetauscht wird, sind vorzugsweise nach der Art von derartigen Einrichtungen ausgebildet, wie sie bei Werkzeugmaschinen, z.B. CNC-Werkzeugmachinen, Verwendung findet.The storage magazine, which is used to replace the forme cylinders, preferably has a drum store in which one or more forme cylinders are stored for replacement. The gripping, rotating and lifting elements with which the forme cylinder is removed from the printing machine and exchanged for another forme cylinder are preferably designed in the manner of such devices as are used in machine tools, e.g. CNC machine tools, used.

Der Formzylinder trägt die Druckform als auswechselbare Hülse. Die Hülse läßt sich leicht entfernen, wenn der Formzylinder zunächst von einer Entnahme-Anordnung aus seiner Lagerung herausgeholt wird, so daß anschließend bei Aufhängung des Formzylinders an einem seiner Zapfen die Hülse vorzugsweise senkrecht nach unten abgezogen werden kann. Dabei trägt aufgrund der Schwerkraft das Gewicht der Hülse dazu bei, daß sie sich leicht entfernen läßt. Der Wechsel der Hülse läßt sich somit durchführen, ohne Löcher in den Seitenwänden des jeweiligen Druckwerks vorsehen oder ein Lager in einem der Zapfen des Formzylinders anordnen zu müssen, um das dieser für den Wechsel der Hülse schwenkbar sein müßte.The forme cylinder carries the printing form as an exchangeable sleeve. The sleeve can be easily removed if the forme cylinder is first taken out of its storage by a removal arrangement, so that the sleeve can then preferably be pulled off vertically downward on one of its pins when the forme cylinder is suspended. The weight of the sleeve contributes to the fact that it can be easily removed due to gravity. The change of the sleeve can thus be carried out without having to provide holes in the side walls of the respective printing unit or having to arrange a bearing in one of the pins of the forme cylinder, about which this should be pivotable for changing the sleeve.

Nachstehend wird anhand der Figuren 1 bis 6 der Austausch eines Formzylinders 5 gegen einen neuen Formzylinder 5' in einer Bogendruckmaschine 1 beschrieben. Bei einem Formzylinder 95, der eine austauschbare Hülse 96 aufweist (Fig. 8 bis 12), läßt sich das Herausnehmen und Wiedereinsetzen des Formzylinders 95 in derselben Weise vollziehen, wie anhand des Wechsels der Formzylinder 5, 5' gemäß Fig. 1 bis 6 in der zugehörigen Beschreibung erläutert wird.The exchange of a forme cylinder 5 for a new forme cylinder 5 'in a sheet-fed printing machine 1 is described below with reference to FIGS. 1 to 6. In the case of a forme cylinder 95 which has an exchangeable sleeve 96 (FIGS. 8 to 12), the removal and reinsertion of the forme cylinder 95 can be carried out in the same way as by changing the forme cylinders 5, 5 'according to FIGS. 1 to 6 in the associated description is explained.

Eine Bogendruckmaschine 1 (Fig. 1) umfaßt einen Bogenspeicher 2 mit den zu druckenden Bögen, einen Bogenanleger 3, der die Bögen an einen Druckzylinder 4 anlegt, auf dessen Umfangsfläche sie von einem Formzylinder 5 über einen Übertragungszylinder 6 im Offset-Druckverfahren bedruckt werden. Die bedruckten Bögen werden von dem Druckzylinder 4 zu einer Abnahmetrommel 7 weitertransportiert. Diese übergibt sie einem hier nicht dargestellten Druckzylinder eines weiteren Druckwerks der Bogendruckmaschine 1.A sheet printing machine 1 (Fig. 1) comprises a sheet storage 2 with the sheets to be printed, a sheet feeder 3, which applies the sheets to a printing cylinder 4, on the circumferential surface of which they are transferred from a forme cylinder 5 via a transfer cylinder 6 Offset printing processes can be printed. The printed sheets are transported from the printing cylinder 4 to a take-up drum 7. It transfers this to a printing cylinder, not shown here, of a further printing unit of the sheet-fed printing press 1.

Die Bogendruckmaschine 1 ist mit einer Auswechseleinheit zum Wechseln des Formzylinders 5 ausgestattet, die ihrerseits einen Greifer 8, eine Hubvorrichtung 9 und einen Doppelgreifer 10 umfaßt, der in einem eigenen Gestell 11 gelagert ist. Der Doppelgreifer 10 trägt bereits einen Formzylinder 5', der gegen den Formzylinder 5 ausgetauscht werden soll, wenn dessen Druckform verdruckt ist oder wenn ein anderer Druckauftrag ausgeführt werden soll. Er fungiert als Zylinderwechselvorrichtung.The sheet-fed printing press 1 is equipped with an exchange unit for changing the forme cylinder 5, which in turn comprises a gripper 8, a lifting device 9 and a double gripper 10 which is mounted in its own frame 11. The double gripper 10 already carries a forme cylinder 5 'which is to be exchanged for the forme cylinder 5 when its printing form is printed or when another print job is to be carried out. It acts as a cylinder changing device.

Der Greifer 8 ist beispielsweise in den Seitenwänden 11 der Bogendruckmaschine 1 in den Richtungen eines Doppelpfeils A schwenkbar befestigt. Der Greifer 8 hat zwei Greifarme 80, die an ihren Enden jeweils mit einem Schenkel 82 und einer Klemmvorrichtung 81 ausgestattet sind, die in ein Aufnahmemittel, z.B. eine Aufnahmenut 51 (Fig. 10) in einem Zapfen 520, des Formzylinders 5 jeweils seitlich der Stirnseiten des Formzylinders 5 hineinpassen.The gripper 8 is, for example, fastened pivotably in the directions of a double arrow A in the side walls 11 of the sheet-fed printing press 1. The gripper 8 has two gripper arms 80, each of which is equipped at its ends with a leg 82 and a clamping device 81, which are inserted into a receiving means, e.g. a receiving groove 51 (FIG. 10) in a pin 520 of the forme cylinder 5 fit into the side of the end faces of the forme cylinder 5.

Wenn also der Formzylinder 5 ausgewechselt werden soll, werden Farbwerkswalzen 130, 131, 132 eines Farbwerks 13 der Bogendruckmaschine 1, die im Schwenkbereich des Formzylinders 5 liegen, zunächst von dem Formzylinder 5 mit nicht näher dargestellten Bewegungsmitteln abgeschwenkt (Pfeil B). Dann greifen der Schenkel 82 und die Klemmvorrichtung 81 an den Greifarmen 80 des Greifers 8 in die jeweilige seitliche Aufnahmenut 51 des Formzylinders 5. Die Klemmvorrichtung 81 preßt den Zapfen 520 des Formzylinders 5 gegen den Schenkel 82, und der Greifer 8 bewegt sich in Richtung zu der Hubvorrichtung 9, die den Formzylinder 5 in ebenfalls dafür vorgesehenen Aufnahmenuten 52 (Fig. 7) in dessen Zapfen 520 mit seinen beiden seitlichen Schenkeln trägt.If the forme cylinder 5 is to be replaced, the inking unit rollers 130, 131, 132 of an inking unit 13 of the sheet-fed printing press 1, which are in the swivel range of the forme cylinder 5, are first pivoted away from the forme cylinder 5 with movement means (not shown) (arrow B). Then the leg 82 and the clamping device 81 on the gripping arms 80 of the gripper 8 engage in the respective lateral receiving groove 51 of the forme cylinder 5. The clamping device 81 presses the pin 520 of the forme cylinder 5 against the leg 82, and the gripper 8 moves in the direction the lifting device 9, which supports the forme cylinder 5 in receiving grooves 52 (FIG. 7), also provided for this purpose, in its pin 520 with its two lateral legs.

Die Hubvorrichtung 9 weist an der Seitenwand 12 der Bogendruckmaschine 1 eine Gewindespindel 91 auf oder ist über eine Zahnstange oder über einen Kettenantrieb in Richtung eines Doppelpfeils C beweglich. Nachdem der Greifer 8 den Formzylinder 5 der Hubvorrichtung 9 übergeben hat, trägt diese den Formzylinder 5 nach oben, um ihn dem Doppelgreifer 10 zu übergeben (Fig. 2). Dieser ist zur Aufnahme des Formzylinders 5 bereits zu der Hubvorrichtung 9 hingeschwenkt. Der Doppelgreifer 10 nimmt den Formzylinder 5 mit seinen beiden Schenkeln wiederum in Aufnahmenuten 51 des Formzylinders 5 auf einem Hebelarm 100 auf. Der Doppelgreifer 10 hat in jedem seiner beiden Hebelarme 100, 101 je ein vor- und zurückziehbares Haltemittel 102 zum Festklemmen des Formzylinders 5 bzw. des Formzylinders 5', der gegen den Formzylinder 5 ausgetauscht werden soll.The lifting device 9 has a threaded spindle 91 on the side wall 12 of the sheet-fed printing machine 1 or is movable in the direction of a double arrow C via a toothed rack or via a chain drive. After the gripper 8 has transferred the forme cylinder 5 to the lifting device 9, it carries the forme cylinder 5 upwards in order to transfer it to the double gripper 10 (FIG. 2). This is already pivoted towards the lifting device 9 for receiving the forme cylinder 5. The double gripper 10 receives the forme cylinder 5 with its two legs in turn in receiving grooves 51 of the forme cylinder 5 on a lever arm 100. The double gripper 10 has in each of its two lever arms 100, 101 a retractable and retractable holding means 102 for clamping the forme cylinder 5 or forme cylinder 5 ', which is to be exchanged for the forme cylinder 5.

Nachdem der Doppelgreifer 10 (Fig. 3) den Formzylinder 5 von der Hubvorrichtung 9 übernommen und ihn mittels des Haltemittels 102 festgeklemmt hat, fährt die Hubvorrichtung 9 wieder nach unten (Doppelpfeil C) aus dem Schwenkbereich des Doppelgreifers 10 heraus.After the double gripper 10 (FIG. 3) has taken over the forme cylinder 5 from the lifting device 9 and clamped it by means of the holding means 102, the lifting device 9 moves down again (double arrow C) out of the pivoting range of the double gripper 10.

Sodann dreht sich der Doppelgreifer 10 (Fig. 4) um 180°, um den Formzylinder 5' in Aufnahmeposition für die Hubvorrichtung 9 zu bringen. Die Hubvorrichtung 9 wird wieder nach oben gefahren, bis sie die Position erreicht, in der sie den Formzylinder 5' übernimmt, sobald das ihn haltende Haltemittel 102 des Doppelgreifers 10 gelöst ist.The double gripper 10 (FIG. 4) then rotates through 180 ° in order to bring the forme cylinder 5 ′ into the receiving position for the lifting device 9. The lifting device 9 is moved up again until it reaches the position in which it takes over the forme cylinder 5 'as soon as the holding means 102 of the double gripper 10 holding it is released.

Die Hubvorrichtung 9 erübrigt sich, wenn der Greifer 8 mit ausfahrbaren Teleskoparmen versehen ist, mit denen er den Formzylinder 5 unmittelbar dem Doppelgreifer 10 übergibt.The lifting device 9 is not necessary if the gripper 8 is provided with extendable telescopic arms with which it transfers the forme cylinder 5 directly to the double gripper 10.

Während nun der Formzylinder 5' (Fig. 5) von der Hubvorrichtung 9 und dem Greifer 8 in derselben Weise in seine Druckposition gebracht wird, wie vorher der Formzylinder 5 aus seiner Position in der Bogendruckmaschine 1 herausgenommen wurde, wobei auch die Farbwerkswalzen 130, 131 und 132 wieder nach unten (Doppelpfeil B) zurückgeschwenkt werden, wird nun der Formzylinder 5, der sich innerhalb des Gestells 11 des Doppelgreifers 10 befindet, für einen erneuten Druckvorgang vorbereitet. Hierzu dient eine Bebilderungseinheit 14, wie sie beispielsweise in Fig. 5 dargestellt ist. Die Bebilderungseinheit 14 ist in einem Gestell 140 angeordnet, welches mit den Seitenwänden 13 des Druckwerks der Bogendruckmaschine 1 integriert ist und ebenfalls das Gestell 11 des Doppelgreifers 10 umfaßt. Die Bebilderungseinheit 14 umfaßt eine Löschvorrichtung 141. Die Löschvorrichtung 141 ist beispielsweise ein Plasmabrenner, der in die Drehachse des Doppelgreifers 10 integriert ist. Der Formzylinder 5 ist in dem Hebelarm 100 des Doppelgreifers 10, der ihn trägt, durch einen Motor, der hier nicht dargestellt ist, drehbar gelagert. Dadurch läßt sich das Bild, das die Druckform auf ihrer Mantelfläche trägt, durch den Plasmabrenner löschen, während der Formzylinder 5 eine Umdrehung um seine Lagerung in dem Hebelarm 100 vollzieht. Die Bebilderungseinheit 14 umfaßt weiterhin eine Bebilderungsvorrichtung 142, um die Druckform auf der Mantelfläche des Formzylinders 5 neu zu beschreiben, z.B. mittels Tintenstrahl oder durch Laserablation. Die Bebilderungsvorrichtung 142 ist in Richtungen eines Doppelpfeils E beweglich auf einer Halterung 143 angeordnet, damit sie bei den Schwenkbewegungen des Doppelgreifers 10 jeweils zur Seite geschoben werden kann, z.B. mittels eines Motors. Außerdem ist eine Fixiervorrichtung 144, z.B. ein IR-Strahler, zum Fixieren des von der Bebilderungsvorrichtung 142 erzeugten Bildes vorhanden, der ebenfalls aus dem Schwenkbereich des Doppelgreifers 10 herausbewegbar ist.While the forme cylinder 5 '(FIG. 5) is now brought into its printing position by the lifting device 9 and the gripper 8 in the same way as the forme cylinder 5 was previously removed from its position in the sheet-fed printing press 1, the inking unit rollers 130, 131 also being taken and 132 down again (double arrow B) be pivoted back, the forme cylinder 5, which is located within the frame 11 of the double gripper 10, is now prepared for a new printing process. An imaging unit 14, such as is shown in FIG. 5, is used for this purpose. The imaging unit 14 is arranged in a frame 140, which is integrated with the side walls 13 of the printing unit of the sheet-fed printing machine 1 and also comprises the frame 11 of the double gripper 10. The imaging unit 14 comprises an erasing device 141. The erasing device 141 is, for example, a plasma torch which is integrated in the axis of rotation of the double gripper 10. The forme cylinder 5 is rotatably mounted in the lever arm 100 of the double gripper 10, which carries it, by a motor, which is not shown here. As a result, the image which the printing form bears on its outer surface can be erased by the plasma torch, while the form cylinder 5 makes one revolution about its mounting in the lever arm 100. The imaging unit 14 further comprises an imaging device 142 in order to rewrite the printing form on the outer surface of the forme cylinder 5, for example by means of inkjet or by laser ablation. The imaging device 142 is arranged movably in the directions of a double arrow E on a holder 143, so that it can be pushed to the side during the pivoting movements of the double gripper 10, for example by means of a motor. In addition, there is a fixing device 144, for example an IR radiator, for fixing the image generated by the imaging device 142, which can also be moved out of the swivel range of the double gripper 10.

Anstelle der Bebilderungseinheit 14 läßt sich auch eine andere Bebilderungseinheit (Fig. 6) vorsehen, die ebenfalls in einem Gestell 150 angeordnet ist und eine Löschvorrichtung 151, z.B. einen Plasmabrenner, umfaßt. Die Bebilderungseinheit 15 weist eine Prägewalze 152 mit einer integrierten Heizung auf, die entsprechend einem auf der Druckform zu erzeugenden Bild Material von einer Folie 153 auf den Formzylinder 5 aufprägt, wobei sich dieser in einer Position 5a befindet. Die Prägefolie 153 wird nach Art eines Films aus einer Kassette 154 abgewickelt, und die verbrauchte Prägefolie 153 wird wieder in einer Kassette 155 aufgewickelt. Dieser Bebilderungsvorgang vollzieht sich, während die Bögen mit dem auf dem Formzylinder 5' aufgebrachten Bild gedruckt werden. Das Druckbild auf der Druckform wird durch eine Fixiervorrichtung 156 fixiert.Instead of the imaging unit 14, another imaging unit (FIG. 6) can also be provided, which is likewise arranged in a frame 150 and comprises an extinguishing device 151, for example a plasma torch. The imaging unit 15 has an embossing roller 152 with an integrated heater which, in accordance with an image to be produced on the printing form, imprints material from a film 153 onto the forme cylinder 5, the latter being in a position 5a. The embossing film 153 is like a film unwound from a cassette 154, and the used embossing foil 153 is wound up again in a cassette 155. This imaging process takes place while the sheets are being printed with the image applied to the forme cylinder 5 '. The printed image on the printing form is fixed by a fixing device 156.

Der Greifer 8 ist vorzugsweise auch in Richtung eines Doppelpfeils C' (Fig. 1 bis 6) verschiebbar.The gripper 8 is preferably also displaceable in the direction of a double arrow C '(FIGS. 1 to 6).

Es ist wichtig, daß die Bebilderungseinheit 14 oder die Bebilderungseinheit 15 erschütterungsfrei gelagert ist. Wenn sie oberhalb des Druckwerkturms angebracht ist, sind geeignete Dämpfungsmittel vorzusehen, um die Schwingungen der Zylinder abzufangen. Wenn eine solche Maßnahme nicht ausreicht, wird die Bebilderungseinheit neben oder unter dem Druckwerksturm angebracht.It is important that the imaging unit 14 or the imaging unit 15 is mounted in a vibration-free manner. If it is installed above the pressure tower, suitable damping devices must be provided to absorb the vibrations of the cylinders. If such a measure is not sufficient, the imaging unit is attached next to or under the printing unit tower.

In der Druckmaschine (16) kann ein Ablagemagazin mit einem Trommelspeicher oder einem Kettenspeicher vorgesehen werden.A storage magazine with a drum store or a chain store can be provided in the printing press (16).

Die in dem Ketten- oder Trommelspeicher gelagerten Formzylinder sind jeweils um ihre Längsachse drehbar und können durch eine Reinigungsvorrichtung die neben dem Ketten- oder Trommelspeicher angeordnet ist, gereinigt werden.The forme cylinders stored in the chain or drum store can each be rotated about their longitudinal axis and can be cleaned by a cleaning device which is arranged next to the chain or drum store.

Der Formzylinder 95 (Fig 8 bis 11) ist in ähnlicher oder in gleicher Weise gelagert wie der Formzylinder 5 (Fig. 7), der in einem Lagerzapfen 505 über eine Lagerung 50 in der Seitenwand 13 (vgl. Fig. 1) gelagert ist. Die Lagerung 50 weist eine Lagerbuchse 500 mit hydraulischer Klemmung auf, in der eine Lagerpinole 501 innerhalb eines Bereiches d parallel zur Längsachse des Formzylinders 5 beweglich angeordnet ist. Über ein axiales Lager 503 und ein radiales Lager 504 ist der Lagerzapfen 505 für den Formzylinder 5 beweglich in der Lagerpinole 501 angeordnet. Der Lagerzapfen 505 ist weiterhin mit einem Formzylinderspanner 506 ausgestattet, der Klemmbacken 507 hat. Diese umschließen einen entsprechenden Spannzapfen 508 des Formzylinders 5 und werden beispielsweise pneumatisch be- und entlastet. Außerdem weisen der Formzylinder 5 und der Lagerzapfen 505 eine Verzahnung 509, beispielsweise eine Hirth-Verzahnung, miteinander auf, durch die der Formzylinder 5 gehalten und auf der Welle zentriert wird.The forme cylinder 95 (FIGS. 8 to 11) is mounted in a similar manner or in the same way as the forme cylinder 5 (FIG. 7), which is mounted in a journal 505 via a bearing 50 in the side wall 13 (see FIG. 1). The bearing 50 has a bearing bush 500 with hydraulic clamping, in which a bearing sleeve 501 within an area d is arranged movably parallel to the longitudinal axis of the forme cylinder 5. The bearing journal 505 for the forme cylinder 5 is movably arranged in the bearing sleeve 501 via an axial bearing 503 and a radial bearing 504. The bearing journal 505 is also equipped with a forme cylinder tensioner 506, which has clamping jaws 507. These enclose a corresponding clamping pin 508 of the forme cylinder 5 and are, for example, pneumatically loaded and unloaded. In addition, the forme cylinder 5 and the bearing journal 505 have a toothing 509, for example a Hirth toothing, with one another, by means of which the forme cylinder 5 is held and centered on the shaft.

Anstelle der hier dargestellten Verzahnung 509 sind auch andere Arten von Verzahnungen möglich, insbesondere solche, deren Zähne an ihren Füßen geneigt sind, so daß der Formzylinder 5 beim Einsetzen in die Druckmaschine selbstzentrierend ist.Instead of the toothing 509 shown here, other types of toothing are possible, in particular those whose teeth are inclined at their feet, so that the forme cylinder 5 is self-centering when inserted into the printing press.

Um die Position des Formzylinders 5 beim Herausnehmen oder beim Wiedereinsetzen genau festzulegen, sind mechanische, optische oder elektronische Positioniermittel einsetzbar.Mechanical, optical or electronic positioning means can be used to precisely determine the position of the forme cylinder 5 when it is removed or reinserted.

Die Rollendruckmaschine 16 ist (Fig. 8, 9) mit einem Formzylinder 96, ausgerüstet, dessen Druckform als auf seinem Mantel kraftschlüssig haftende, auswechselbare Hülse 96 ausgebildet ist. Diese Ausgestaltung der Druckform ist an sich beispielsweise bereits aus der DE 35 43 704 A1 bekannt. Gemäß der Erfindung wird der Formzylinder 95 durch eine Entnahme-Anordnung 90 mittels Greifern 92 und 93 herausgehoben. Die Greifer 92 und 93 halten den Formzylinder 95 jeweils in den Nuten 51 in dessen Zapfen 520, 520'. Die Entnahme-Anordnung 90 fährt anschließend auf dem Schienengestell 23 von dem Druckwerk weg und dreht den Formzylinder um eine Drehachse 900 in die senkrechte Lage. Der Greifer 93 wird nach unten in Richtung eines Pfeils K von dem Zapfen 520' abgeschwenkt, so daß der Formzylinder 95 von unten frei zugänglich ist und seine Hülse 96 durch eine hier nicht dargestellte Wechselvorrichtung gegen eine Ersatzhülse austauschbar ist. Anschließend fährt der Greifer 97 wieder in die Halteposition zurück, der Formzylinder 95 wird wieder in die waagrechte Lage gedreht und zur Fortsetzung des Druckprozesses in das Druckwerk wieder eingesetzt.The web printing machine 16 is (Fig. 8, 9) equipped with a forme cylinder 96, the printing form of which is designed as an interchangeably adhering sleeve 96 on its jacket. This configuration of the printing form is known per se, for example from DE 35 43 704 A1. According to the invention, the forme cylinder becomes 95 lifted out by a removal arrangement 90 by means of grippers 92 and 93. The grippers 92 and 93 each hold the forme cylinder 95 in the grooves 51 in its pin 520, 520 '. The removal arrangement 90 then moves away from the printing unit on the rail frame 23 and rotates the forme cylinder about an axis of rotation 900 into the vertical position. The gripper 93 is pivoted downward in the direction of an arrow K from the pin 520 ', so that the forme cylinder 95 is freely accessible from below and its sleeve 96 can be exchanged for a replacement sleeve by a changing device, not shown here. The gripper 97 then moves back into the holding position, the forme cylinder 95 is rotated again into the horizontal position and is inserted into the printing unit again in order to continue the printing process.

Wenn die Druckmaschinen 1, 16 mehrere Druckwerke aufweisen, kann die Auswechseleinheit mit ihren Greifern 8 und die Zylinderwechselvorrichtung 10 sowie die Entnahme-Anordnung 90 jeweils zwischen zwei Druckwerken angeordnet sein und den Wechsel von Hülsen in ihnen ausführen. Dazu ist die Auswechseleinheit mit den Greifern 8; um ihre senkrechte Achse drehbar gelagert.If the printing presses 1, 16 have a plurality of printing units, the exchange unit with its grippers 8 and the cylinder changing device 10 and the removal arrangement 90 can each be arranged between two printing units and carry out the exchange of sleeves in them. For this purpose, the exchange unit with the grippers 8; pivoted about its vertical axis.

In Figur 10 ist die Bogendruckmaschine 1 mit dem Formzylinder 95 mit der auswechselbaren Hülse 96 dargestellt, der dem mit dem gleichen Bezugszeichen versehenen Formzylinder der Rollendruckmaschine 16 in Fig. 7 und 8 entspricht. Im übrigen entsprechen die in Fig. 10 dargestellten Teile und Elemente den in Fig. 1 bis 6 dargestellten Teilen und Elementen; sie sind daher mit den gleichen Bezugszeichen versehen und werden hier nicht mehr näher erläutert. Die Hubvorrichtung 9 weist zwei Greifarme 901, 902 auf. Der Greifarm 901 weist eine hier nicht dargestellte Klemmvorrichtung auf, mit der er den Formzylinder 95 an seinem Zapfen 520 einklemmen und halten kann. Der Greifarm 901 ist vorzugsweise zusätzlich noch gegenüber dem Greifarm 902 einzeln verfahrbar. Mittels der Klemmvorrichtung umgreift er den Zapfen 520' des Formzylinders 95 und dreht diesen um 90° um seine Drehachse in Richtung eines Pfeils L nach oben. In dieser Position ist die Hülse 96 des Formzylinders 95 mittels einer hängend angeordneten und hier nicht dargestellten Abziehvorrichtung von dem Formzylinder 95 abziehbar und gegen eine Ersatz-Hülse austauschbar. Nachdem dieselbe eingesetzt ist, wird der Formzylinder 95 durch die genau umgekehrten Bewegungsabläufe wieder in den Druckwerksturm der Bogendruckmaschine 1 eingesetzt.FIG. 10 shows the sheet-fed printing press 1 with the forme cylinder 95 with the exchangeable sleeve 96, which corresponds to the forme cylinder of the web printing press 16 with the same reference number in FIGS. 7 and 8. Otherwise, the parts and elements shown in FIG. 10 correspond to the parts and elements shown in FIGS. 1 to 6; they are therefore provided with the same reference numerals and are no longer explained here. The lifting device 9 has two gripping arms 901, 902. The gripper arm 901 has a clamping device, not shown here, with which it can clamp and hold the forme cylinder 95 on its pin 520. The gripping arm 901 is preferably additionally movable individually in relation to the gripping arm 902. By means of the clamping device it engages around the pin 520 'of the forme cylinder 95 and rotates it 90 ° about its axis of rotation in the direction of an arrow L upwards. In this position, the sleeve 96 of the forme cylinder 95 can be removed from the forme cylinder 95 by means of a hanging pulling device which is not shown here and can be exchanged for a replacement sleeve. After the same has been inserted, the forme cylinder 95 is reinserted into the printing unit tower of the sheet-fed printing press 1 due to the exactly opposite movement sequences.

Figur 11 zeigt wieder die Bogendruckmaschine 1 mit einem oberhalb des Druckwerksturms angeordneten Gestell 11', das größer ausgebildet ist als das Gestell 11 (Fig. 10). Der Greifarm 901 der Hubvorrichtung 9 ist wieder so ausgebildet, daß er allein den Formzylinder 95 mit der auswechselbaren Hülse 96 zu tragen vermag. Im Unterschied zu der anhand von Fig. 10 dargestellten Ausführungsform der Erfindung dreht der Greifarm 901 in diesem Fall den Formzylinder 95 um 90° nach unten, so daß dieser senkrecht an ihm hängt. Durch eine hier nicht dargestellte Entnahme-Vorrichtung läßt sich dann die Hülse 96 des Formzylinders 95 nach unten abziehen, wobei vorzugsweise der andere Greifarm 902 der Hubvorrichtung 9 nach unten (Doppelpfeil C) weggefahren ist, um Platz zu schaffen, wie in Fig. 11 dargestellt.FIG. 11 again shows the sheet-fed printing press 1 with a frame 11 ′ which is arranged above the printing unit tower and is larger than the frame 11 (FIG. 10). The gripping arm 901 of the lifting device 9 is again designed such that it alone can carry the forme cylinder 95 with the exchangeable sleeve 96. In contrast to the embodiment of the invention shown in FIG. 10, the gripper arm 901 in this case rotates the forme cylinder 95 by 90 ° so that it hangs vertically on it. By means of a removal device, not shown here, the sleeve 96 of the forme cylinder 95 can then be pulled downwards, the other gripper arm 902 of the lifting device 9 preferably being moved downwards (double arrow C) in order to create space, as shown in FIG. 11 .

Eine andere Variante dieser Bogendruckmaschine 1 zeigt Figur 12. Dort wird der Formzylinder 95 ebenfalls von dem Greifarm 901 der Hubvorrichtung 9 gehalten und festgeklemmt. Weil bei dieser Bogendruckmaschine 1 das Gestell 11 oder 11' nicht vorhanden ist, läßt sich der an dem Greifarm 901 gehaltene Formzylinder um seinen Zapfen 520' oberhalb des Druckwerksturms in der waagrechten Ebene in Richtung eines Pfeils M drehen, nachdem der andere Greifarm 902 der Hubvorrichtung 9 wieder ein Stück nach unten aus dem Schwenkbereich des Greifarms 901 ausgefahren ist. Anschließend läßt sich die Hülse 96 waagrecht durch eine hier ebenfalls nicht dargestellte Entnahmevorrichtung von dem Formzylinder 95 abziehen und durch eine andere Ersatz-Hülse austauschen. Durch die entsprechenden umgekehrten Bewegungsabläufe wird der Formzylinder 95 wieder in seine Lagerung 50 in der Bogendruckmaschine 1 eingesetzt.Another variant of this sheet-fed printing machine 1 is shown in FIG. 12. There the forme cylinder 95 is also held and clamped by the gripping arm 901 of the lifting device 9. Because the frame 11 or 11 'is not present in this sheet-fed printing press 1, the forme cylinder held on the gripper arm 901 can be rotated in the horizontal plane in the direction of an arrow M around its pin 520' above the printing unit tower, after the other gripper arm 902 of the lifting device 9 is again extended a little downward from the swivel range of the gripping arm 901. Subsequently, the sleeve 96 can be removed horizontally from the forme cylinder 95 by a removal device, also not shown here, and exchanged for another replacement sleeve. Through the corresponding reverse movements the forme cylinder 95 is reinserted into its mounting 50 in the sheet-fed printing press 1.
