Description

Die Erfindung betrifft eine Druckmaschine mit einer Vorrichtung zur Einstellung oder Einstellung und Identifizierung von auf Formzylindern der Druckmaschine aufgebrachten Druckformen in Abhängigkeit von Parametern der jeweiligen Druckform.The invention relates to a printing press with a device for adjusting or setting and identification of printing cylinders applied to the printing cylinders of the printing machine as a function of parameters of the respective printing forme.

Aus der EP 1 559 572 A1 geht ein System hervor, mit dessen Hilfe die Position eines RFID-Bausteins ermittelt werden kann, wobei in einem nachfolgenden Schritt anhand der ermittelten Position die Einstellung der Druckmaschine vorgesehen ist.From the EP 1 559 572 A1 goes out a system with the help of which the position of an RFID module can be determined, wherein in a subsequent step on the basis of the determined position, the setting of the printing press is provided.

Die WO 2004/098890 A1 offenbart eine Ermittlung der Positionen von Druckformträgern anhand von Sensoren, um anschließend mit Hilfe einer Steuervorrichtung eine Registereinstellung für die jeweiligen Druckformträger durchzuführen. Hierzu soll auf der Druckform ein Informationsträger vorgesehen sein, dem durch einen Sensor Informationen entnehmbar sind, die zur Feststellung der relativen Lage des Druckformträgers auf dem Dorn oder Zylinder einer Rotationsdruckmaschine geeignet sind.The WO 2004/098890 A1 discloses a determination of the positions of printing form carriers by means of sensors, in order subsequently to perform a register setting for the respective printing form carriers with the aid of a control device. For this purpose, an information carrier is to be provided on the printing form, which information can be removed by a sensor, which are suitable for determining the relative position of the printing form carrier on the mandrel or cylinder of a rotary printing press.

Die GB 2 424 392 A offenbart eine Druckplattenerkennung auf der Basis von RFID-Bausteinen, um bei einer Druckmaschine mit einer Vielzahl von Druckwalzen eine fehlerhafte Anbringung einer Druckplatte an einer Druckwalze zu vermeiden.The GB 2 424 392 A discloses a printing plate recognition based on RFID components to be used in a printing press with a plurality of pressure rollers to avoid incorrect attachment of a pressure plate to a pressure roller.

Hierbei ist vorgesehen, eine Druckplatte einer Auslesevorrichtung zuzuführen und den Druckplattencode vom RFID-Baustein auszulesen, um dann nach Auswertung des Druckplattencodes eine Anzeige der korrekte Druckwalze sowie der Druckplattenposition auf der Druckwalze zu ermöglichen.In this case, it is provided to supply a printing plate to a read-out device and to read out the printing plate code from the RFID module, in order to then enable, after evaluation of the printing plate code, an indication of the correct printing roller and the printing plate position on the printing roller.

Aus der EP 1593505 A2 ist ein Verfahren zur schnellen Kontrolle eines Druckbildes auf einer Druckform bekannt. Nach exakter Positionierung der Druckform an Passstiften wird über ein Kamerasystem sowohl das Druckbild als auch eine in Form einer Marke neben dem Druckbild angeordnete Bezugsposition erfasst. Aus dem Kamerabild wird dann die Bezugsposition des Druckbildes auf der Druckform mittels eines Rechnersystems ermittelt. Das Ergebnis dient zur Einstellung der jeweiligen Druckform auf dem Formzylinder der Druckmaschine und/oder zur Einstellung der Position des mit der Druckform versehenen Formzylinders bzw. der Bogenübergabeelemente. Nachteilig an dem bekannten Verfahren ist es, dass die ermittelten Korrekturdaten auf dem Rechnersystem gespeichert sind, wobei jeweils eine Zuordnung der zugehörigen Druckform erfolgen muss.From the EP 1593505 A2 is a method for rapid control of a printed image on a printing form known. After exact positioning of the printing form on dowel pins, a camera system records both the printed image and a reference position arranged in the form of a mark next to the printed image. The reference position of the printed image on the printing form is then determined from the camera image by means of a computer system. The result serves to set the respective printing forme on the forme cylinder of the printing press and / or for adjusting the position of the forme cylinder or sheet transfer elements provided with the printing form. A disadvantage of the known method is that the determined correction data are stored on the computer system, in each case an assignment of the associated printing form must be carried out.

Dies ist zum einen relativ umständlich und kann zu Verwechslungen von Druckformen führen.This is on the one hand relatively cumbersome and can lead to confusion of printing forms.

Eine Aufgabe der vorliegenden Erfindung besteht darin, eine Druckmaschine mit einer Vorrichtung zu schaffen, durch die eine automatische Positionierung der Druckform beziehungsweise des entsprechenden Formzylinders möglich wird, ohne dass zuvor irgendwelche Zuordnungen erforderlich wären.An object of the present invention is to provide a printing machine with a device by which an automatic positioning of the printing plate or the corresponding forme cylinder is possible without the need for any prior assignments.

Diese Aufgabe wird erfindungsgemäß durch eine Druckmaschine mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a printing press with the features of claim 1.

In vorteilhafter Weise werden die beispielsweise durch das bekannte Verfahren erfassten Korrekturdaten sowie optional weitere Parameter der jeweiligen Druckform auf einem sich auf dieser befindlichen Transponder direkt gespeichert. Hierdurch wird nicht nur erreicht, dass eine eindeutige Zuordnung dieser Transponderdaten zur jeweiligen Druckform gewährleistet ist, sondern die Transponderdaten können auch automatisch über das Transponder-Übertragungssystem von der jeweiligen Druckmaschine ausgelesen werden und können dann zur manuellen oder automatischen motorischen Einstellung der Position der Druckform auf dem jeweiligen Formzylinder oder zur Einstellung des jeweiligen Formzylinders in der Maschine dienen. Neben den Korrekturdaten, beispielsweise Verstelldaten für das Umfang-, Seiten- und Diagonalregister, können als weitere Transponderdaten beziehungsweise Parameter auch eine Auftragsnummer, die zugehörige Druckfarbe, das zugehörige Druckwerk, die Zusammensetzung und die Reihenfolge des Plattensatzes und dergleichen im Transponder gespeichert werden. Diese Transponderdaten lassen sich auch in einfacher Weise ändern und ergänzen, wobei zusätzliche Transponderdaten beispielsweise die Häufigkeit des Platteneinsatzes oder zusätzliche Korrekturgrößen oder Transponderdaten für Folgeaufträge sein können. Durch die Möglichkeit einer Identifizierung solcher Druckformen über große Distanzen mittels Transpondersystemen wird auch ein leichtes Auffinden und Identifizieren von Druckformen in einem Archiv oder Magazin möglich. Eine Verwechslung von Druckformen ist kaum mehr möglich.Advantageously, the correction data acquired, for example, by the known method and optionally further parameters of the respective printing form are stored directly on a transponder located thereon. This not only ensures that an unambiguous assignment of these transponder data is guaranteed to the respective printing form, but the transponder data can also be read automatically via the transponder transmission system of the respective printing press and can then for manual or automatic motorized adjustment of the position of the printing plate on the each form cylinder or to adjust the respective forme cylinder in the machine. In addition to the correction data, such as adjustment data for the perimeter, page and diagonal register, as an additional transponder data or parameters and an order number, the associated ink, the associated printing unit, the composition and the order of the plate set and the like are stored in the transponder. These transponder data can also be changed and supplemented in a simple manner, wherein additional transponder data can be, for example, the frequency of the disk insert or additional correction variables or transponder data for subsequent jobs. The possibility of identifying such printing forms over long distances by means of transponder systems also makes it easy to find and identify printing forms in an archive or magazine. A confusion of printing forms is hardly possible anymore.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Vorrichtung möglich.The measures listed in the dependent claims advantageous refinements and improvements of claim 1 device are possible.

In vorteilhafter Weise ist die Leseeinrichtung (Reader) für die Transponderdaten am oder im Bereich des Druckwerks der Druckmaschine ortsfest angeordnet, zu der der jeweilige Formzylinder gehört. Aufgrund der relativ großen Reichweiten der Transponderdatenübertragung wird diese direkte Übertragung ermöglicht.Advantageously, the reading device (reader) for the transponder data is fixedly arranged on or in the region of the printing unit of the printing press to which the respective form cylinder belongs. Due to the relatively large ranges of transponder data transmission, this direct transmission is made possible.

Alternativ hierzu kann die Leseeinrichtung (Reader) für die Transponderdaten auch am Formzylinder, insbesondere an oder in einer Festspanneinrichtung für die Druckform, angeordnet sein, wobei ein mit der Leseeinrichtung verbundener Datenübertrager zur weiteren Datenübertragung zur Auswerteeinrichtung hin ausgebildet ist. Dieser weitere Datenübertrager kann als weiterer Transponder ausgebildet sein. Hierdurch ist eine noch sicherere Datenübertragung gewährleistet.Alternatively, the reading device (reader) for the transponder data can also be arranged on the forme cylinder, in particular on or in a clamping device for the printing forme, wherein a data transmitter connected to the reading device is designed for further data transmission to the evaluation device. This additional data transmitter can be designed as another transponder. This ensures even more secure data transmission.

Zur einfachen und sicheren Auslösung der Datenübertragung ist in vorteilhafter Weise eine Sensoreinrichtung am Formzylinder zur Erfassung der korrekten Anlageposition der Druckform vorgesehen, wobei ein bei korrekter Position ausgelöstes Signal auch zur Auslösung der Datenübertragung ausgebildet ist. Die Sensoreinrichtung ist bevorzugt als an einer in Ausnehmungen der Druckform eingreifende Passstiftanordnung am Formzylinder ausgebildet, wobei die Passstiftanordnung und die Ausnehmungen ohnehin vorhanden sind, sodass keine zusätzlichen Hardware-Maßnahmen erforderlich sind.For simple and reliable triggering of data transmission, a sensor device is advantageously provided on the forme cylinder for detecting the correct abutment position of the printing form, wherein a signal triggered in the correct position is also designed to trigger the data transmission. The sensor device is preferably embodied as a dowel pin arrangement engaging recesses in the printing form on the forme cylinder, the dowel pin arrangement and the recesses being present anyway, so that no additional hardware measures are required.

Der Transponder ist zweckmäßigerweise an der Anlageseite der Druckform angeordnet, insbesondere im Bereich der Festspanneinrichtung des Formzylinders, da dort radial nach innen gerichtete Hohlräume vorhanden sind.The transponder is expediently arranged on the contact side of the printing form, in particular in the region of the clamping device of the forme cylinder, since there are radially inwardly directed cavities.

Anstelle einer manuellen Positionierung von Druckform und/oder Formzylindern in Abhängigkeit der übermittelten Transponderdaten kann in vorteilhafter Weise die Auswerteeinrichtung auch zur automatischen Steuerung der motorisch einstellenden Einstellmittel ausgebildet sein.Instead of a manual positioning of the printing forme and / or forme cylinders as a function of the transmitted transponder data, the evaluation device can also be designed to automatically control the motor-adjusting means.

In einer bevorzugten Ausführung ist die Datenübertragungseinrichtung wenigstens teilweise als RFID-System (Radio Frequency Identification) ausgebildet.In a preferred embodiment, the data transmission device is at least partially designed as an RFID system (Radio Frequency Identification).

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen:

An embodiment of the invention is illustrated in the drawing and explained in more detail in the following description. Show it:
FIG. 1
a side view of a provided with a printing plate designed as a plate cylinder in a partial view and
FIG. 2
a plan view of the voltage applied to dowel pins on the forme cylinder printing form.

Beim in den Figuren 1 und 2 dargestellten Ausführungsbeispiel besitzt ein in der Teildarstellung dargestellter Formzylinder 10 einer im Übrigen nicht dargestellten Druckmaschine in an sich bekannter Weise eine Festspanneinrichtung 11 zum Festspannen einer als Druckplatte 12 ausgebildeten Druckform. Eine Druckmaschine besitzt üblicherweise mehrere Druckwerke für die verschiedenen Farben, wobei jedes Druckwerk mindestens einen Formzylinder 10 besitzt, auf dem die jeweilige Druckplatte 12 festgespannt werden kann.When in the Figures 1 and 2 illustrated embodiment has a shown in the partial view of the form cylinder 10 of a printing machine, not shown, in a conventional manner a tightening device 11 for clamping a pressure plate 12 formed as a printing plate. A printing machine usually has several printing units for the different colors, each printing unit has at least one forme cylinder 10, on which the respective pressure plate 12 can be tightened.

Zum exakten Positionieren der Druckplatte 12 auf dem Formzylinder 10 besitzt die Druckplatte 12 zwei randseitige Positionierausnehmungen 13, 14, wobei beim Aufbringen der Druckplatte 12 auf den Formzylinder 10 die Druckplatte 12 so an der Festspanneinrichtung 11 angelegt wird, dass dort vorhandene Passstifte 15, 16 in die Positionierausnehmungen 13, 14 eingreifen. Diese sind üblicherweise mit Sensoren versehen, die das Erreichen der korrekten Anlageposition entweder nur anzeigen oder alternativ oder zusätzlich den Festspannvorgang der Festspanneinrichtung 11 auslösen.For exact positioning of the pressure plate 12 on the forme cylinder 10, the pressure plate 12 has two peripheral positioning recesses 13, 14, wherein the pressure plate 12 is applied to the clamping device 11 during application of the pressure plate 12 on the forme cylinder 10 so that there existing dowel pins 15, 16 in the positioning recesses 13, 14 engage. These are usually provided with sensors that either only indicate the achievement of the correct contact position or alternatively or additionally trigger the tightening operation of the clamping device 11.

Beim Aufbringen eines Druckbilds 17 auf die Druckplatte 12 muss auf die Genauigkeit der Zuordnung zwischen Druckbild und Positionierausnehmungen 13, 14 geachtet werden, die auch als Passstanzungen bezeichnet werden. Im eingangs genannten Stand der Technik ( EP 1593505 A2 ) ist ein Verfahren beschrieben, um eine schnelle Lagekontrolle eines Druckbilds auf der Druckplatte 12 durchzuführen. Dies erfolgt mittels eines Kamerasystems. Das Ergebnis, also das Feststellen von eventuellen Abweichungen, erhält man als Datensatz. Gemäß der vorliegenden Erfindung wird dieser Datensatz in einem Transponder 18 gespeichert, der an der Druckplatte 12 fixiert ist. Gemäß Figur 1 ist dieser Transponder 18 an der Anlage- oder Unterseite der Druckplatte 12 zum Formzylinder 10 hin an einer Stelle fixiert, an der neben der Festspanneinrichtung 11 ein kleiner Hohlraum vorhanden ist. Dies verhindert zum einen eine Beschädigung des Transponders 18 und zum anderen eine ungleiche Auflage auf dem Formzylinder 10. Der Transponder 18 kann beispielsweise als Aufkleber mittels eines Etikettenspenders bei der Bestimmung des Druckbildstandes aufgebracht werden.When applying a printed image 17 to the printing plate 12, attention must be paid to the accuracy of the association between the printed image and the positioning recesses 13, 14, which are also referred to as punch punches. In the aforementioned prior art ( EP 1593505 A2 ), a method is described for performing a rapid position control of a printed image on the printing plate 12. This is done by means of a camera system. The result, ie the determination of possible deviations, is obtained as a data record. According to the present invention, this data record is stored in a transponder 18 which is fixed to the printing plate 12. According to FIG. 1, this transponder 18 is fixed on the contact or underside of the pressure plate 12 to the forme cylinder 10 at a point at which a small cavity is present in addition to the clamping device 11. This prevents on the one hand damage to the transponder 18 and, on the other hand, an unequal overlay on the forme cylinder 10. The transponder 18 can be applied, for example, as a label by means of a label dispenser in the determination of the printed image.

Neben der Einspeicherung von Korrekturdaten beziehungsweise Positionierdaten können noch weitere Transponderdaten in den Transponder 18 eingespeichert werden, beispielsweise Identifikationsdaten für die Druckplatte 12 oder Druckform, Auftragsnummerndaten, Zuordnung des Druckwerks, Zusammengehörigkeit und Reihenfolge des Plattensatzes, Daten für Folgeaufträge und dergleichen. Die Korrekturdaten beziehungsweise Positionierdaten können Daten zur Korrektur der Position der Druckplatte 12 auf dem Formzylinder 10 sein oder Positionierdaten für den Formzylinder 10, beispielsweise Verstelldaten für Umfang-, Seiten- und Diagonalregister.In addition to the storage of correction data or positioning data even more transponder data in the Transponder 18 are stored, for example, identification data for the printing plate 12 or printing form, order number data, assignment of the printing unit, togetherness and order of the plate set, data for follow-up orders and the like. The correction data or positioning data may be data for correcting the position of the printing plate 12 on the forme cylinder 10 or positioning data for the forme cylinder 10, for example adjustment data for circumferential, lateral and diagonal registers.

Zur Datenübertragung der Transponderdaten dient eine Datenübertragungseinrichtung, die beispielsweise als RFID-System ausgebildet ist. Eine solche Datenübertragungseinrichtung besteht aus dem Transponder 18 selbst und einer Leseeinrichtung 19, die beim Ausführungsbeispiel an der Festspanneinrichtung 11 des Formzylinders 10 im Nahbereich des Transponders 18 angeordnet ist und die auch als Reader bezeichnet wird. Diese Leseeinrichtung 19 kann prinzipiell auch an einer anderen Stelle des Formzylinders 10 angeordnet sein. Sie ist mit einem Datensender 20 verbunden, der beim Ausführungsbeispiel ebenfalls in der Festspanneinrichtung 11 angeordnet ist und beispielsweise ebenfalls als Transponder-Datenübertragungseinrichtung ausgebildet sein kann, das heißt, dieser Datensender 20 enthält ebenfalls einen Transponder oder besteht aus einem solchen. Die Transponderdaten vom Transponder 18 werden in diesen Datensender 20 eingelesen und drahtlos einer externen Auswerteeinrichtung 21 übermittelt, die im Falle einer Transponder-Datenübertragungseinrichtung ebenfalls eine Leseeinrichtung (Reader) enthält. Diese ist beispielsweise an der zugehörigen Druckmaschine beziehungsweise am zugehörigen Druckwerk oder in der Nähe desselben angeordnet und über Leitungen oder wirkungsmäßig mit dieser beziehungsweise diesem verbunden.For data transmission of the transponder data is a data transmission device, which is designed for example as an RFID system. Such a data transmission device consists of the transponder 18 itself and a reading device 19, which is arranged in the embodiment of the clamping device 11 of the forme cylinder 10 in the vicinity of the transponder 18 and which is also referred to as a reader. This reading device 19 can in principle also be arranged at a different location of the forme cylinder 10. It is connected to a data transmitter 20, which is also arranged in the clamping device 11 in the embodiment and, for example, can also be designed as a transponder data transmission device, that is, this data transmitter 20 also contains a transponder or consists of such. The transponder data from the transponder 18 are read into this data transmitter 20 and transmitted wirelessly to an external evaluation device 21, which also contains a reading device (reader) in the case of a transponder data transmission device. This is arranged, for example, on the associated printing press or on the associated printing unit or in the vicinity of the same and connected via lines or operatively connected to this or this.

Wird die korrekte Anlage der Druckplatte 12 an der Festspanneinrichtung 11 mittels der Sensoren an den Passstiften 15, 16 festgestellt, so schließt zum einen die Festspanneinrichtung 11 und gleichzeitig oder danach wird ein Auslösesignal an den Datensender 20 übermittelt, das diesen veranlasst, die Transponderdaten an die Auswerteeinrichtung 21 zu übermitteln. Die Transponderdaten werden dort ausgewertet und können im einfachsten Falle manuell zur Korrektur der Position des Formzylinders 10 verwendet werden, oder sie dienen zur automatischen motorischen Positionskorrektur des Formzylinders 10, also zur Verstellung des entsprechenden Umfang-, Seiten- und/oder Diagonalregisters.If the correct installation of the pressure plate 12 on the clamping device 11 detected by the sensors to the dowel pins 15, 16, so on the one hand, the clamping device 11 and simultaneously or thereafter, a trigger signal is transmitted to the data transmitter 20, which causes these, the transponder data to the To transmit evaluation device 21. The transponder data are evaluated there and can be used in the simplest case manually to correct the position of the forme cylinder 10, or they are used for automatic motor position correction of the forme cylinder 10, so for adjusting the corresponding perimeter, page and / or diagonal register.

Die Auswertung der Transponderdaten kann auch wenigstens zum Teil in einer internen Auswerteeinrichtung 22 am Formzylinder 10 beziehungsweise in oder an der Festspanneinrichtung 11 erfolgen.The evaluation of the transponder data can also be carried out at least partially in an internal evaluation device 22 on the forme cylinder 10 or in or on the tightening device 11.

Da Transponderübertragungssysteme heutzutage eine relativ große Reichweite haben, kann die Übertragung der Transponderdaten vom Transponder 18 auch direkt zur externen Auswerteeinrichtung 21 ohne Zwischenschaltung eines Datensenders 20 und einer internen Leseeinrichtung 19 erfolgen. Die Auswerteeinrichtung 21 enthält dann eine entsprechende Leseeinrichtung (Reader).Since transponder transmission systems today have a relatively large range, the transmission of the transponder data from the transponder 18 can also take place directly to the external evaluation device 21 without the interposition of a data transmitter 20 and an internal reading device 19. The evaluation device 21 then contains a corresponding reading device (reader).

Wenn der Transponder 18 auch Identifikationsdaten für die jeweilige Druckplatte 12 enthält, kann dies auch in einfacher Weise zum Auffinden einer bestimmten Druckplatte 12 in einem Druckplatten-Magazin dienen. Darüber hinaus lassen sich alle im Druckplatten-Magazin gespeicherten Druckplatten oder sonstige Druckformen identifizieren, das heißt, der gesamte Inhalt des Magazins kann gleichzeitig ausgelesen und registriert werden.If the transponder 18 also contains identification data for the respective printing plate 12, this can also be used in a simple manner for finding a specific printing plate 12 in a printing plate magazine. In addition, all printing plates or other printing forms stored in the printing plate magazine can be identified, that is, the entire contents The magazine can be read out and registered at the same time.

Die Transponderdaten können auch nachträglich noch verändert oder ergänzt werden, zum Beispiel können dadurch die Häufigkeit des Platteneinsatzes, die Einsatzorte, Korrekturdaten aus der letzten laufenden Produktion und dergleichen in den Transponder eingeschrieben werden.The transponder data can also be subsequently changed or supplemented, for example, by the frequency of disk use, the locations, correction data from the last ongoing production and the like are written into the transponder.
