Abstract

A process for replacing the printing sleeves of a printing machine includes mounting printing sleeves that are not required for the printing process in at least one storage device. The transportation of the printing sleeves necessary for replacement between the storage device and the printing machine is performed by a transportation device. The transportation device has printing sleeve retaining devices that bring the printing sleeves into a position that facilitates their replacement. The arrangement of the printing sleeves in the transportation device is determined by a processing and control unit to which set positions of the printing sleeves during the next printing job are known. The processing and control unit adjusts the arrangement of the printing sleeves such that at least one printing sleeve retaining device remains free in the transportation device.

Description

Verfahren zum Wechseln von Druckhülsen In einer Druckmaschine Process for changing printing sleeves in a printing press
Die Erfindung betrifft ein Verfahren zum Wechseln von Druckhülsen in einer Druckmaschine gemäß des Oberbegriffs des Anspruchs 1The invention relates to a method for changing printing sleeves in a printing press according to the preamble of claim 1
Zur Abwicklung von Druckaufträgen ist es häufig notwendig, die Druckmotive der Druckwalzen einer Druckmaschine zu wechseln. Um diesen Auftragswechsel möglichst schnell und einfach durchführen zu können, werden häufig nur die Druckhülsen, welche die Druckmotive tragen und auf den Walzendornen aufliegen, ausgewechselt.To process print jobs, it is often necessary to change the print motifs on the printing rollers of a printing press. In order to be able to carry out this job change as quickly and easily as possible, often only the printing sleeves that carry the printing motifs and rest on the roller mandrels are replaced.
Die noch unveröffentlichte Patentanmeldung DE 102 23 414 zeigt eine Transportvorrichtung für Druckhülsen mit einer Mehrzahl von Tragedornen zur Aufnahme der Druckhülsen. Jeweils zwei benachbarte Tragedorne haben dabei einen Abstand, der dem Abstand der Druck- und Rasterwalze in deren Rüstpositionen entspricht. Diese beiden Tragedorne bilden eine Zeile innerhalb der Transportvorrichtung. Die Transportvorrichtung ist an eine an der Druckmaschine befestigten Hubvorrichtung ankoppelbar und damit relativ zur Druckmaschine horizontal und vertikal verfahrbar.The as yet unpublished patent application DE 102 23 414 shows a transport device for printing sleeves with a plurality of carrying mandrels for receiving the printing sleeves. Two adjacent mandrels each have a distance that corresponds to the distance between the printing and anilox rollers in their set-up positions. These two mandrels form a line within the transport device. The transport device can be coupled to a lifting device attached to the printing press and can thus be moved horizontally and vertically relative to the printing press.
Soll nun eine Druckhülse gewechselt werden, muss das Bedienpersonal zunächst die Transportvorrichtung mit den in die Druckmaschine einzubringenden Druckhülsen bestücken und die Transportvorrichtung vor dem Druckwerk, in dem sich die zu wechselnden Druckhülsen befinden, mit Hilfe der Hubvorrichtung positionieren, so dass zwei freie Tragedorne vor den Druckwalzen positioniert sind. Dann können die auf den Druckwalzendörnen befindlichen Druckhülsen vom Bedienpersonal abgezogen werden. Anschließend wird die Transportvorrichtung neu positioniert, um die aufzuschiebenden Druckhülsen in eine passende Lage zum Aufschieben auf die Walzendorne zu bringen. Dann können die Druckhülsen aufgeschoben werden. Gegebenenfalls wird für weitere Druckwerke auf gleiche Weise verfahren.If a printing sleeve is now to be changed, the operating personnel must first equip the transport device with the printing sleeves to be inserted into the printing press and the transport device in front of the printing unit in which the printing sleeves to be changed are located position the lifting device so that two free mandrels are positioned in front of the pressure rollers. Then the printing sleeves on the printing roller mandrels can be removed by the operating personnel. The transport device is then repositioned in order to bring the pressure sleeves to be pushed onto a suitable position for being pushed onto the roll mandrels. Then the pressure sleeves can be pushed on. If necessary, the same procedure is followed for other printing units.
Bei den beschriebenen Verfahren zum Wechseln von Druckhülsen einer Druckmaschine erfolgt die Bestückung der Transportvorrichtung durch das Bedienpersonal, wobei es keine festgelegte Anordnung der Druckhülsen in der Transportvorrichtung gibt. Das Bedienpersonal muss also selbstständig eine Anordnung der Druckhülsen in der Transportvorrichtung entwerfen, wobei die Anordnung zum Teil ungünstig für den Rüstvorgang ist. Zudem besteht die Gefahr einer fehlerhaften Zuordnung der Druckhülsen zu den Walzendornen.In the described methods for changing printing sleeves of a printing press, the transport device is loaded by the operating personnel, there being no fixed arrangement of the printing sleeves in the transport device. The operating personnel must therefore independently design an arrangement of the pressure sleeves in the transport device, the arrangement being in part unfavorable for the setup process. There is also the risk of incorrect assignment of the pressure sleeves to the roll mandrels.
Die Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zum Wechseln von Druckhülsen in Druckmaschinen vorzuschlagen, das das Wechseln von Druckhülsen vereinfacht.The object of the present invention is therefore to propose a method for changing printing sleeves in printing presses, which simplifies the changing of printing sleeves.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim 1.

Die Rechen- und Steuereinheit berücksichtigt dabei alle relevanten Druckhülsen, also nicht nur diejenigen, die der Druckmaschine zugeführt werden sollen, sondern auch solche, die aus der Druckmaschine abgeführt und der Speichervorrichtung zugeführt werden müssen. Als Grundlage für die Bestimmung der Anordnung verwendet die Rechen- und Steuereinheit Daten über die Sollpositionen der einzelnen Druckhülsen zur Bearbeitung des neuen Druckauftrags sowie Daten über die aktuellen Positionen von Druckhülsen in der Druckmaschine. Auch Daten über die Positionen der Druckhülsen in der Speichervorrichtung können der Rechen- und Steuereinheit bekannt sein.Pressure sleeve receiving device remains free in the transport device. The computing and control unit takes into account all relevant printing sleeves, not only those that are to be fed to the printing press, but also those that have to be removed from the printing press and fed to the storage device. As the basis for To determine the arrangement, the computing and control unit uses data about the target positions of the individual printing sleeves for processing the new print job and data about the current positions of printing sleeves in the printing press. Data about the positions of the printing sleeves in the storage device can also be known to the computing and control unit.

Eine Zeile der Transporteinrichtung ist dabei einem bestimmten Druckwerk zugeordnet. Für jedes Druckwerk ist also zumindest eine leereThe computing and control unit advantageously determines the arrangement of the printing sleeves in the transport device such that at least one empty printing sleeve receiving device and the at least one new printing sleeve required for the new print job are contained in each line. One line of the transport device is assigned to a specific printing unit. So there is at least one empty one for each printing unit
Druckhülsenaufnahmevorrichtung vorgesehen. Ist das . Druckwerk beispielsweise horizontal angeordnet, können die in einer Zeile angeordneten Druckhülsenaufnahmevorrichtungen ebenfalls horizontal angeordnet sein. In diesem Fall muss nach dem Abschieben einer Druckhülse eines abgearbeiteten Druckauftrags die Transportvorrichtung nur horizontal verschoben werden, um eine Position zu erreichen, in welcher eine neue Druckhülse auf den Walzendorn aufgeschoben werden kann.Pressure sleeve receiving device provided. Is this . For example, if the printing unit is arranged horizontally, the printing sleeve receiving devices arranged in one row can also be arranged horizontally. In this case, after a printing sleeve of a processed print job has been pushed off, the transport device only has to be moved horizontally in order to reach a position in which a new printing sleeve can be pushed onto the roll mandrel.
In einer weiteren bevorzugten Ausführungsform der Erfindung bestimmt die Rechen- und Steuereinheit die Anordnung der Druckhülsen in der Transportvorrichtung derart, dass eine Zeile vonIn a further preferred embodiment of the invention, the computing and control unit determines the arrangement of the printing sleeves in the transport device such that a line of
Druckhülsenaufnahmevorrichtungen frei bleibt und die anderen Zeilen die den jeweiligen Druckwerken zugeordneten Druckhülsen enthalten. In diesem Fall werden also zunächst alle Druckhülsen eines Druckwerks von den Walzendomen entfernt. Sodann wird die Transportvorrichtung vertikal verschoben, so dass die dem betreffenden Druckwerk zugeordneten neuen Druckhülsen in eine für den Wechsel geeigneten Position gebracht werden können. Es ist besonders vorteilhaft, wenn die von einer Rechen- und Steuereinheit bestimmte Anordnung der Druckhülsen in der Transportvorrichtung auf einer Anzeigeeinheit angezeigt wird. Als Anzeigeeinheit kann ein Bildschirm vorgesehen sein, jedoch eignen sich zu diesem Zweck auch weitere Mittel zum Anzeigen der Anordnung, beispielsweise Ausdrucke eines Druckers.Printing sleeve receiving devices remains free and the other lines contain the printing sleeves assigned to the respective printing units. In this case, all printing sleeves of a printing unit are first removed from the roller domes. The transport device is then moved vertically so that the new printing sleeves assigned to the printing unit in question can be brought into a position suitable for the change. It is particularly advantageous if the arrangement of the printing sleeves in the transport device determined by a computing and control unit is displayed on a display unit. A screen can be provided as the display unit, but other means for displaying the arrangement, for example printouts of a printer, are also suitable for this purpose.
In einer bevorzugten Ausführungsform der Erfindung wird die von der Rechen- und Steuereinheit bestimmte Anordnung der Druckhülsen in der Transportvorrichtung vom Bedienpersonal vorgenommen. Das Bedienpersonal entnimmt dazu der Speichervorrichtung die entsprechenden Druckhülsen und ordnet diese gemäß der auf der Anzeigeneinheit dargestellten Anordnung in der Transportvorrichtung ein.In a preferred embodiment of the invention, the arrangement of the printing sleeves in the transport device determined by the computing and control unit is carried out by the operating personnel. For this purpose, the operating personnel takes the corresponding pressure sleeves from the storage device and arranges them in the transport device in accordance with the arrangement shown on the display unit.
Besonders vorteilhaft ist es, wenn die Rechen- und Steuereinheit über Schnittstellen zu Aktuatoren der Speicher- und/oder Transportvorrichtung verfügt und diese so ansteuert, dass sie den Transfer zwischen den beiden vorgenannten Vorrichtungen zumindest teilweise durchführen. Zu diesemIt is particularly advantageous if the computing and control unit has interfaces to actuators of the storage and / or transport device and controls them in such a way that they carry out the transfer between the two aforementioned devices at least partially. To this

A such control is used for the automatic transfer of the transport device to the printing press and back. The control can further comprise the coupling and uncoupling of the transport device to and / or from a lifting device and the method of the transport device relative to the printing press.
In einer bevorzugten Ausführungsform steuert die Rechen- und Steuereinheit aufgrund der von ihr bestimmten Anordnung der Druckhülsen in der Transportvorrichtung die Position der Transportvorrichtung relativ zur Druckmaschine so, dass leere Druckhülsenaufnahmevorrichtungen in eine Entnahmeposition zu den mit den auszuwechselnden Druckhülsen beaufschlagten Walzendornen gebracht werden und anschließend die mit den neuen Druckhülsen beaufschlagten Druckhülsenaufnahmevorrichtungen in die Wechselposition gebracht werden. Bei dieser Vorgehensweise kann das Bedienpersonal zunächst eine Druckhülse des bereits bearbeiteten Druckauftrags von dem Walzendorn entfernen und auf eine leere Druckhülsenaufnahmevorrichtung aufschieben. Hat das Bedienpersonal der Rechen- und Steuereinheit die Beendigung dieser Tätigkeit, beispielsweise über einen Tastendruck, angezeigt, so steuert die Rechen- und Steuereinheit die Aktuatoren derart an, dass die Druckhülse des neuen Druckauftrags, die auf den Walzendorn aufgeschoben werden soll, in die Wechselposition gebracht wird. Dieses Verfahren wird für alle Walzendorne durchgeführt, von welchen eine Druckhülse entfernt und/oder eine Druckhülse aufgeschoben werden soll.In a preferred embodiment, the computing and control unit controls the position of the transport device relative to the printing machine based on the arrangement of the printing sleeves in the transport device that it determines, so that empty printing sleeve receiving devices are brought into a removal position with respect to the roller mandrels loaded with the printing sleeves to be replaced and then with the new pressure sleeves pressurized sleeve receiving devices are brought into the change position. With this procedure, the operating personnel can first remove a printing sleeve from the already processed print job from the roll mandrel and slide it onto an empty printing sleeve receiving device. If the operating personnel of the computing and control unit have indicated that this activity has ended, for example by pressing a button, the computing and control unit controls the actuators in such a way that the printing sleeve of the new print job, which is to be pushed onto the roller mandrel, is in the change position brought. This process is carried out for all roll mandrels from which a pressure sleeve is to be removed and / or a pressure sleeve is to be pushed on.
Die einzige Figur zeigt eine Druckmaschine, die nach dem erfindungsgemäßen Verfahren gerüstet wird.The only figure shows a printing press which is set up using the method according to the invention.
Die Druckmaschine 1 umfasst zwei Seitengestelle, von denen das vordere Seitengestell 2 zu sehen ist. Von dem vorderen Seitengestell 2 sind mehrereThe printing press 1 comprises two side frames, of which the front side frame 2 can be seen. There are several of the front side frame 2
Druckwerke zugänglich, von denen exemplarisch zwei Druckwerke 3, 4 dargestellt sind. Von dem Druckwerk 3 sind die beiden Lagerböcke 22 zu sehen, die sich in abgerückter Position befinden, so dass die Druckwalze 5 und die Rasterwalze 6 zugänglich sind. Die Druckwalze 5 besteht im wesentlichen aus dem Walzendorn 8 und der darauf aufgeschobenen Druckhülse 7. In gleicher Weise ist die Rasterwalze 6 aufgebaut.Printing units accessible, of which two printing units 3, 4 are shown as examples. The two bearing blocks 22 are closed by the printing unit 3 see who are in the moved position so that the printing roller 5 and the anilox roller 6 are accessible. The printing roller 5 essentially consists of the roller mandrel 8 and the printing sleeve 7 pushed thereon. The anilox roller 6 is constructed in the same way.
Um die unteren Druckwerke, von denen nur das Druckwerk 4 gezeigt ist, erreichen zu können, kann der Laufsteg 10, welcher in dem Podest 12 gelagert ist, entlang des Pfeils A verschoben werden. Zusätzlich kann eine der beiden Treppen 11 eingeklappt werden.In order to be able to reach the lower printing units, of which only the printing unit 4 is shown, the catwalk 10, which is mounted in the platform 12, can be moved along the arrow A. In addition, one of the two stairs 11 can be folded.
Die Druckmaschine umfasst weiterhin eine Hubvorrichtung 15, mit welcher eine Transportvorrichtung 13 relativ zur Druckmaschine 1 verfahren werden kann. Eine horizontale Bewegung wird durch eine an dem Seitengestell 2 befestigten Laufschiene 17 ermöglicht. Zum Anheben der Transportvorrichtung 13 dient eine Seilwinde 16, die auf der Laufschiene 17 verschieblich gelagert ist.The printing press further comprises a lifting device 15 with which a transport device 13 can be moved relative to the printing press 1. Horizontal movement is made possible by a running rail 17 attached to the side frame 2. A cable winch 16, which is displaceably mounted on the running rail 17, is used to lift the transport device 13.
Zum Rüsten der Druckmaschine 1 für einen neuen Druckauftrag kann das Bedienpersonal zunächst der Rechen- und Steuereinheit 19 über eine Tastatur 21 Informationen über den neuen Druckauftrag erteilen. Anschließend berechnet die Rechen- und Steuereinheit die Anordnung der Druckhülsen , in der Transportvorrichtung 13. Nun muss das Bedienpersonal 9 auf nicht näher dargestellte Weise die Transportvorrichtung 13 gemäß der von der Rechen- und Steuereinheit 19 bestimmten Anordnung bestücken. Zu diesem Zweck wird diese Anordnung auf dem Bildschirm 20 dargestellt. Anschließend begibt sich das Bedienpersonal 9 zum ersten Druckwerk 3, von dem die Druckhülsen 7 entfernt werden müssen. Die Rechen- und Steuereinheit 19 steuert die Hubvorrichtung 15 über die Steuerleitung 18 derart, dass zunächst ein freier Tragedom 14 der Transportvorrichtung 13 in eine Position gebracht wird, die ein Abziehen einer Druckhülse 7 von dem Walzendorn 8 ermöglicht. Nach dem Verschieben der Druckhülse 7 von dem Walzendorn 8 auf einen Tragedorn 14 betätigt das Bedienpersonal 9 einen nicht dargestellten Taster. Die Rechen- und Steuereinheit 19 steuert nun die Hubvorrichtung 15, so dass ein Tragedorn 14, auf dem sich eine neue Druckhülse 7 befindet, eine Wechselposition einnimmt. Nach dem Verschieben dieser Druckhülse 7 betätigt das Bedienpersonal 9 erneut den nicht dargestellten Taster.To prepare the printing press 1 for a new print job, the operating personnel can first give the computing and control unit 19 information about the new print job via a keyboard 21. The computing and control unit then calculates the arrangement of the printing sleeves in the transport device 13. Now the operating personnel 9 must equip the transport device 13 in a manner not shown in accordance with the arrangement determined by the computing and control unit 19. For this purpose, this arrangement is shown on the screen 20. The operating personnel 9 then go to the first printing unit 3, from which the printing sleeves 7 have to be removed. The computing and control unit 19 controls the lifting device 15 via the control line 18 in such a way that first a free carrying dome 14 of the transport device 13 is brought into a position which enables a pressure sleeve 7 to be pulled off the roller mandrel 8. After moving the pressure sleeve 7 from the roller mandrel 8 to a carrying mandrel 14, the operating personnel 9 actuates a button (not shown). The computing and control unit 19 now controls the lifting device 15, so that a carrying mandrel 14, on which there is a new pressure sleeve 7, assumes an exchange position. After moving this pressure sleeve 7, the operating personnel 9 actuates the button (not shown) again.
Die beschriebene Vorgehensweise wird nun für alle weiteren Druck- und/oder Rasterwalzen 5, 6, welche für neuen Druckauftrag ausgerüstet werden müssen, durchgeführt. The procedure described is now carried out for all further printing and / or anilox rollers 5, 6 which have to be equipped for a new print job.
