Description

Die Erfindung bezieht sich auf eine Druckmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a printing machine according to the preamble of Claim 1.

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 plates must be used be replaced. To do this, the entire printing press must be stopped; the change of printing forms is usually done by hand. But there are also automatic changeover systems known (robotics). For form printing machines cylinders are partially replaced by hand. For gravure printing machines, that is 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 auszuwechseln. 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. From US 5 186 103 a printing press is known, in particular for Printing on a paper web made of heavy or hard cardboard material, and which has interchangeable cylinders. Because according to the different too printing packaging materials, the images to be printed differ Having widths and lengths, it is necessary to use form cylinders with different Use and replace diameters. It is either just that Forme cylinder (for direct printing) or the forme cylinder together with the Transfer cylinder (for offset printing) in an exchangeable cassette arranged out of the respective printing unit tower of the printing press is removable. A conveyor winch, which is on a Rail is arranged movably. First she pulls the cassette up and then transported them away to another cassette with one Forme cylinder or a forme cylinder in connection with a Exchange cylinder that has a different diameter or have.

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 an exchange process that is not just taking out a single one Forme cylinder, but also removing a cartridge that is in the side wall of the respective printing unit is attached, is very expensive. It leads to a long standstill of the machine when changing the Forme cylinder and the associated change of printing forms. By the A printing press comes to a standstill, however, the water-color balance The inking unit and dampening unit of the printing press are disturbed and must be used again be reset.

Es ist die Aufgabe der Erfindung, eine Druckmaschine zu schaffen, in der die Formzylinder leicht auswechselbar sind, so daß zwischen Druckaufträgen flexibel gewechselt werden kann oder eine Reinigung leicht möglich ist.It is the object of the invention to provide a printing press in which the Forme cylinders are easily interchangeable, so flexible between print jobs can be changed or cleaning is easily possible.

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.

Vorteilhaft ist es insbesondere, daß, nachdem der verdruckte Formzylinder mit der verdruckten Form ausgetauscht worden ist, der verdruckte Formzylinder während des Druckens mit dem eingetauschten Formzylinder erneuert werden kann. Dies kann beispielsweise dadurch geschehen, daß der Formzylinder eine konventionelle Druckform trägt, die manuell gegen eine neue Druckform ausgetauscht wird, wofür dann soviel Zeit zur Verfügung steht, wie der eingetauschte Formzylinder zum Drucken dient. Der Wechsel der Druckform kann jedoch auch durch einen Roboter geschehen. Besonders geeignet ist jedoch 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 Oberfläche 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.It is particularly advantageous that after the printed form cylinder with the printed form has been replaced, the printed form cylinder during printing can be renewed with the exchanged forme cylinder. This can be done, for example, in that the forme cylinder is a conventional one Printing form that is exchanged manually for a new printing form for what then as much time is available as the exchanged forme cylinder for Print serves. However, a robot can also change the printing form happen. However, a forme cylinder is particularly suitable, which with a renewable printing form is covered. At the time when the other forme cylinder is used for printing, the printed form can be deleted by an eraser delete and then re-image. This is done, for example, by a Ink printing process or by a thermal transfer process with a film that covered the forme cylinder. For the renewal of the surface of the forme cylinder there is enough time available. The fact that the forme cylinder from the Printing machine is unloaded and not imaged in itself again there are no 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 defines defined interfaces between the printing press, d. H. the storage of the forme cylinder in the side walls of the printing press, and created the form cylinder itself. To get it right and full in to store the printing press are, for example, in the side walls in the direction bearing sleeves movable for the forme cylinder along the longitudinal axis of the forme cylinder, Forme cylinder clamps and spur gears between the cylinder bearing and the Form cylinder provided.

Das Ablagemagazin, das zum Auswechseln der Formzylinder dient, weist vorzugsweise einen Trommelspeicher auf, in dem ein 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-Werkzeugmaschinen, Verwendung findet.The storage magazine, which is used to replace the forme cylinder, has preferably a drum store in which one or more forme cylinders is or will be stored for replacement. The gripping, rotating and lifting elements, with which the forme cylinder is removed from the printing press and is exchanged for another forme cylinder, are preferably after Kind of such devices trained as they are in machine tools, for.

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 memory 2 with the printing sheets, a sheet feeder 3, the sheets to a printing cylinder 4th creates, on the circumferential surface of a forme cylinder 5 via a Transfer cylinder 6 are printed using the offset printing process. The printed ones Sheets are transferred from the impression cylinder 4 to a take-up drum 7 transported on. It transfers this to a printing cylinder, not shown here another 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 equipped, which in turn a gripper 8, a lifting device 9 and comprises a double gripper 10 which is mounted in its own frame 11. The Double gripper 10 already bears a forme cylinder 5 ′ that bears against the forme cylinder 5 should be replaced if the printing form is printed or if a another print job is to be executed. It acts as 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, in the side walls 11 of the sheet-fed printing press 1 pivotally attached in the directions of a double arrow A. The gripper 8 has two Gripping arms 80, each with a leg 82 and one at their ends Clamping device 81 are equipped, which in a receiving means, for. Legs Receiving groove 51 (FIG. 10) in a pin 520, the forme cylinder 5 laterally fit into the front 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. 10) in dessen Zapfen 520 mit seinen beiden seitlichen Schenkeln trägt. So if the forme cylinder 5 is to be replaced, inking rollers 130, 131, 132 of an inking unit 13 of the sheet-fed printing press 1, which in The pivoting range of the forme cylinder 5 is initially with the forme cylinder 5 Movement means not shown are pivoted away (arrow B). Then grab the leg 82 and the clamping device 81 on the gripper arms 80 of the gripper 8 into 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 of the lifting device 9, which the forme cylinder 5 in also provided grooves 52 (Fig. 10) in the pin 520 with his two side thighs.

Die Hubvorrichtung 9 weist an der Seitenwand 12 der Bogendruckmaschine 1 eine Gewindespindel 91 auf oder ist über eine Zahnstange oder über einen Kettenantrie 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 on the side wall 12 of the sheet-fed printing press 1 Threaded spindle 91 on or is via a rack or via a chain drive movable in the direction of a double arrow C. After the gripper 8 the Form cylinder 5 has passed the lifting device 9, this carries the form cylinder 5th upwards to hand it over to the double gripper 10 (FIG. 2). This is for Recording of the forme cylinder 5 already pivoted towards the lifting device 9. The Double gripper 10 takes the form 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 one in front and in each of its two lever arms 100, 101 retractable holding means 102 for clamping the forme cylinder 5 or the 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) removes the forme cylinder 5 from the lifting device 9 has taken over and clamped it by means of the holding means 102, the Lifting device 9 down again (double arrow C) from the swivel range of the Double gripper 10 out.
