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

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Wechseln von Druckhülsen in einer Druckmaschine gemäß des Oberbegriffs der Ansprüche 1 und 8.The invention relates to a method and a device for changing printing sleeves in a printing press according to the preamble of claims 1 and 8.

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.For the processing of print jobs, it is often necessary to change the print motifs of the printing rollers of a printing press. In order to carry out this job change as quickly and easily as possible, often only the printing sleeves, which carry the print motifs and rest on the rolling mandrels, 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befestigten Hubvorrichtung ankoppelbar und damit relativ zur Druckmaschine horizontal und vertikal verfahrbar.The still unpublished patent application DE 102 23 414 shows a transport device for printing sleeves with a plurality of support pins for receiving the printing sleeves. In each case two adjacent support pins have a distance corresponding to the distance of the printing and anilox roller in their setup positions. These two support pins form a row within the transport device. The transport device can be coupled to a lifting device fastened to the printing press and thus 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 now a printing sleeve to be changed, the operator must first equip the transport device with the introduced into the printing press sleeves and the transport device in front of the printing unit in which there are to be replaced printing sleeves, with the help Position the lifting device so that two free support pins are positioned in front of the pressure rollers. Then the pressure sleeves located on the print roller loops can be removed by the operating personnel. Subsequently, the transport device is repositioned to bring the aufzuschiebenden printing sleeves in a suitable position for sliding onto the rolling mandrels. Then the pressure sleeves can be pushed. If necessary, the procedure is the same 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 method for changing printing sleeves of a printing machine, the loading of the transport device by the operating personnel, there is no fixed arrangement of the pressure sleeves in the transport device. The operating personnel must therefore independently design an arrangement of the pressure sleeves in the transport device, wherein the arrangement is partly unfavorable for the setup process. In addition, there is a risk of incorrect assignment of the printing sleeves to the rolling mandrels.

Ein Verfahren und eine Vorrichtung gemäß dem Oberbegriff der Ansprüche 1 und 8 ist auch vom Dokument US 2002/0056392 bekannt.A method and apparatus according to the preamble of claims 1 and 8 is also of the document US 2002/0056392 known.

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 exchange of printing sleeves.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils der Ansprüche 1 und 8 gelöst.According to the invention this object is solved by the features of the characterizing part of claims 1 and 8.

Demnach wird die Anordnung der Druckhülsen in der Transportvorrichtung von einer Rechen- und Steuereinheit bestimmt. Die Anordnung der Druckhülsen wird dabei so eingerichtet, dass zumindest eine Druckhülsenaufnahmeeinrichtung in der Transportvorrichtung frei bleibt. 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.Accordingly, the arrangement of the pressure sleeves in the transport device is determined by a computing and control unit. The arrangement of the pressure sleeves is set up so that at least one compression 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 supplied to the printing press, but also those that must be removed from the printing press and the storage device must be supplied. As a basis for the Determination of the arrangement uses the arithmetic and control unit data on the nominal positions of the individual printing sleeves for processing the new print job and data on the current positions of printing sleeves in the printing press. Also, data about the positions of the printing sleeves in the storage device may be known to the computing and control unit.

Vorteilhafterweise bestimmt die Rechen- und Steuereinheit die Anordnung der Druckhülsen in der Transportvorrichtung derart, dass in jeder Zeile zumindest eine leere Druckhülsenaufnahmevorrichtung und die zumindest eine für den neuen Druckauftrag benötigte neue Druckhülse enthalten sind. Eine Zeile der Transporteinrichtung ist dabei einem bestimmten Druckwerk zugeordnet. Für jedes Druckwerk ist also zumindest eine leere 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.Advantageously, the arithmetic and control unit 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 printing job are contained in each line. One line of the transport device is assigned to a specific printing unit. For each printing unit so at least one empty printing sleeve receiving device is provided. For example, if the printing unit is arranged horizontally, the printing sleeve receiving devices arranged in a row can likewise be arranged horizontally. In this case, after the removal of a printing sleeve of a processed print job, the transport device must only be moved horizontally in order to reach a position in which a new printing sleeve can be pushed onto the roller mandrel.

In einer weiteren bevorzugten Ausführungsform der Erfindung bestimmt die Rechen- und Steuereinheit die Anordnung der Druckhülsen in der Transportvorrichtung derart, dass eine Zeile von 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 Walzendornen 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.In a further preferred embodiment of the invention, the arithmetic and control unit determines the arrangement of the printing sleeves in the transport device such that one line of printing sleeve receiving devices remains free and the other lines contain the printing sleeves associated with the respective printing units. In this case, therefore, first all printing sleeves of a printing unit are removed from the rolling mandrels. Then, the transport device is moved vertically, so that the respective printing unit associated new printing sleeves can be brought into a suitable position for the change.

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.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. As a display unit, a screen may be provided, but are suitable for this purpose, further means for displaying the arrangement, such as prints of a printer.

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 operator. For this purpose, the operator removes the corresponding pressure sleeves from the storage device and arranges them in the transport device according to 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 diesem Zweck hat die Rechen- und Steuereinheit Zugang zu Daten, die die Positionen jeder einzelnen Druckhülse in der Speichervorrichtung beinhaltet. Auf diese Weise kann die Transportvorrichtung mit Druckhülsen, beispielsweise mit Hilfe einer Greifervorrichtung, bestückt werden, ohne dass Vertauschungen vorkommen. Auf gleiche Weise werden die aus der Druckmaschine entfernten und in der Transportvorrichtung transportierten Druckhülsen der Speichervorrichtung zugeführt werden, wobei die die Positionen der Druckhülsen beinhaltenden Daten für die Rechen- und Steuereinheit zugänglich bleiben. Hierzu kann ein mit der Rechen- und Steuereinheit verbundener Datenspeicher dienen.It is particularly advantageous if the arithmetic and control unit has interfaces to actuators of the storage and / or transport device and controls them in such a way that they at least partially carry out the transfer between the two aforementioned devices. For this purpose, the computing and control unit has access to data that includes the locations of each individual printing sleeve in the storage device. In this way, the transport device can be equipped with pressure sleeves, for example with the aid of a gripper device, without permutations occurring. In the same way, the printing sleeves removed from the printing press and transported in the transporting device are fed to the storage device, the data containing the positions of the printing sleeves remaining accessible to the computing and control unit. For this purpose, a data memory connected to the computing and control unit can be used.

Vorteilhaft ist weiterhin, wenn die Rechen- und Steuereinheit über Schnittstellen zu Aktuatoren der Transportvorrichtung und/oder der Druckmaschine verfügt und diese so ansteuert, dass sie den Transfer zwischen den beiden vorgenannten Vorrichtungen zumindest teilweise durchführen. Eine derartige Ansteuerung dient dem automatischen Transfer der Transportvorrichtung zur Druckmaschine und zurück. Die Ansteuerung kann weiterhin das An- und Abkoppeln der Transportvorrichtung an und/oder von einer Hubvorrichtung sowie das Verfahren der Transportvorrichtung relativ zur Druckmaschine umfassen.It is also advantageous if the computing and control unit has interfaces to actuators of the transport device and / or the printing press and controls them so that they perform the transfer between the two aforementioned devices at least partially. A Such control is used for automatic transfer of the transport device to the printing press and back. The control may 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 arithmetic and control unit controls the position of the transport device relative to the printing press so that empty Druckhülsenaufnahmevorrichtungen are brought into a removal position to be acted upon by the printing sleeves to be replaced Walzendornen and then the with the new printing sleeves acted upon Druckhülsenaufnahmevorrichtungen be brought into the change position. In this approach, the operator can first remove a printing sleeve of the already processed print job from the roller mandrel and postpone it to an empty printing sleeve receiving device. If the operating personnel of the computing and control unit has indicated the termination of this activity, for example via a keystroke, the arithmetic and control unit controls the actuators in such a way that the pressure sleeve of the new print job which is to be pushed onto the roller mandrel is in the interchangeable position is brought. This method is carried out for all rolling mandrels from which a pressure sleeve is removed and / or a pressure sleeve to be pushed.

Die einzige Figur zeigt eine Druckmaschine, die nach dem erfindungsgemäßen Verfahren gerüstet wird.The single FIGURE shows a printing press which is prepared by 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 mehrere 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.The printing machine 1 comprises two side frames, of which the front side frame 2 can be seen. From the front side frame 2 more printing units are accessible, of which two printing units 3, 4 are exemplified. From the printing unit 3, the two bearing blocks 22 to see that are in the extended position, so that the pressure roller 5 and the anilox roller 6 are accessible. The pressure roller 5 consists essentially of the roller mandrel 8 and the pressure sleeve 7 pushed onto it. 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 reach the lower printing units, of which only the printing unit 4 is shown, the catwalk 10, which is mounted in the pedestal 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 machine further comprises a lifting device 15, with which a transport device 13 can be moved relative to the printing press 1. A horizontal movement is made possible by a running rail 17 fastened to the side frame 2. To lift the transport device 13 is a winch 16 which is slidably mounted on the running rail 17.

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 Tragedorn 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 set up the printing machine 1 for a new print job, the operator can first give the computing and control unit 19 via a keyboard 21 information about the new print job. Subsequently, the computing and control unit calculates the arrangement of the printing sleeves in the transport device 13. Now, the operating personnel 9 in a manner not shown to equip the transport device 13 according to the determined by the computing and control unit 19 arrangement. For this purpose, this arrangement is displayed on the screen 20. Subsequently, the operator 9 goes to the first printing unit 3, from which the printing sleeves 7 must be removed. The arithmetic and control unit 19 controls the lifting device 15 via the control line 18 such that initially a free support mandrel 14 of the transport device 13 is brought into a position which allows removal of a pressure sleeve 7 of the roller mandrel 8. After moving the pressure sleeve 7 of the roller mandrel 8 on a support mandrel 14 actuates the operator 9 a button, not shown. The computing and control unit 19 now controls the lifting device 15, so that a support mandrel 14, on which there is a new pressure sleeve 7, assumes a change position.
