Description
Die Erfindung betrifft ein Verfahren zur Handhabung von Druckplatten an einer Rollendruckmaschine, nämlich zur Anordnung von Druckplatten in bei einem Druckplattenwechsel als Druckplattenspeicher dienenden Kassetten, nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for handling printing plates on a web-fed printing press, namely for the arrangement of printing plates in cartridges serving as printing plate stores in the case of a printing plate change, according to the preamble of claim 1.
Zur Ausführung eines Druckplattenwechsels müssen im Bereich einer Rollendruckmaschine Druckplatten gehandhabt werden. Dabei ist es von Bedeutung, dass zur Ausführung eines Druckplattenwechsel jede Druckplatte dem richtigen Druckwerk der richtigen Druckeinheit einer Rollendruckmaschine zugeführt wird, und dass jede Druckplatte innerhalb des richtigen Druckwerks an der richtigen Plattenzylinderposition auf dem Plattenzylinder des Druckwerks gespannt wird. Bei Rollendruckmaschinen mit einem manuellen Druckplattenwechsel werden die Druckplatten an den Plattenzylinderpositionen der Druckwerke der Druckeinheiten einer Rollendruckmaschine von einem Drucker manuell bereitgehalten. Bei Druckmaschinen mit einem automatisierten Druckplattenwechsel erfolgt das Bereitstellen der Druckplatten an den Plattenzylinderpositionen der Druckwerke der Druckeinheiten einer Rollendruckmaschine mit Hilfe von Kassetten, die als Druckplattenspeicher dienen. Die in den Kassetten bereitgehaltenen Druckplatten können mit Hilfe eines Manipulatorarms aus den Kassetten automatisch entnommen und den Plattenzylindern der Druckwerke automatisch zugeführt werden.To perform a printing plate change printing plates must be handled in the area of a web press. It is important that each plate is fed to the correct printing unit of the correct printing unit of a web press to perform a printing plate change, and that each printing plate is clamped within the correct printing unit at the correct plate cylinder position on the plate cylinder of the printing unit. In web-fed presses with a manual printing plate change, the printing plates are manually held ready at the plate cylinder positions of the printing units of the printing units of a web-fed printing press by a printer. In printing presses with an automated printing plate change, the printing plates are provided at the plate cylinder positions of the printing units of the printing units of a web-fed printing press with the aid of cartridges, which serve as printing plate stores. The printing plates kept in the cassettes can be automatically removed from the cassettes by means of a manipulator arm and automatically fed to the plate cylinders of the printing units.
Sowohl bei Rollendruckmaschinen mit einem manuellen Druckplattenwechsel als auch bei Rollendruckmaschinen mit einem automatischen Druckplattenwechsel kann es zu Fehlbelegungen bei einem Druckplattenwechsel kommen, d. h. Druckplatten können den falschen Druckwerken bzw. den falschen Plattenzylinderpositionen an einem Druckwerk zugeführt werden.Both with web presses with a manual plate change and with web presses with an automatic plate change can lead to incorrect assignments in a printing plate change, ie printing plates can be fed to the wrong printing units or the wrong plate cylinder positions on a printing unit.
Bei einem manuellen Druckplattenwechsel kann diese Fehlbelegung dadurch erfolgen, dass ein Drucker eine Druckplatte an einem falschen Druckwerk bzw. an einer falschen Plattenzylinderposition zum Druckplattenwechsel bereithält. Bei einem automatischen Druckplattenwechsel kann eine derartige Fehlbelegung dadurch verursacht werden, dass Druckplatten in falschen Kassetten oder an falschen Aufnahmepositionen innerhalb einer Kassette bereitgehalten werden.In the case of a manual printing plate change, this misregistration can take place in that a printer holds a printing plate at a wrong printing unit or at a wrong plate cylinder position for the printing plate change. In an automatic printing plate change, such misregistration can be caused by holding printing plates in wrong cassettes or in wrong receiving positions within a cassette.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein neuartiges Verfahren zur Handhabung von Druckplatten zu schaffen. Diese Aufgabe wird durch ein Verfahren gemäß Anspruch 1 gelöst.On this basis, the present invention has the object to provide a novel method for handling printing plates. This object is achieved by a method according to claim 1.
Mit dem erfindungsgemäßen Verfahren kann sichergestellt werden, dass Druckplatten zur Ausführung eines automatisierten Druckplattenwechsels sowohl in den richtigen Kassetten als auch an den richtigen Aufnahmepositionen innerhalb der Kassetten, die als Druckplattenspeicher dienen, bereitgehalten werden. Die Anordnung der Druckplatten in den Kassetten ist eineindeutig, so dass Fehlbelegungen von Druckplatten an Plattenzylindern auf ein absolutes Minimum reduziert werden können.The method according to the invention makes it possible to ensure that printing plates for carrying out an automated printing plate change are kept ready both in the correct cassettes and in the correct receiving positions within the cassettes which serve as printing plate stores. The arrangement of the printing plates in the cassettes is unambiguous so that misplacements of printing plates on plate cylinders can be reduced to an absolute minimum.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, nachfolgend näher erläutert.Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be explained in more detail below, without being limited thereto.
Die hier vorliegende Erfindung betrifft ein Verfahren zur Handhabung von Druckplatten an einer Rollendruckmaschine, nämlich zur Anordnung von Druckplatten in bei einem automatisierten Druckplattenwechsel als Druckplattenspeicher dienenden Kassetten.The present invention relates to a method for handling printing plates on a web-fed printing press, namely for the arrangement of printing plates in cartridges used in an automated printing plate change as a print-plate storage.
Im Sinne der hier.vorliegenden Erfindung wird jede Druckplatte mit einer Codierung versehen, wobei die Codierung eindeutig identifiziert, an welcher Plattenzylinderposition welches Druckwerks welcher Druckeinheit einer Rollendruckmaschine die jeweilige Druckplatte verwendet wird. Die Codierung wird jeder Druckplatte vor dem Belichten oder beim Belichten oder im Anschluss an das Belichten zugeordnet. Die Codierung enthält eine eindeutige Information zum Zielort der Druckplatte.For the purposes of the present invention, each printing plate is provided with a coding, wherein the coding clearly identifies at which plate cylinder position which printing unit which printing unit of a web-fed printing press the respective printing plate is used. The coding is assigned to each printing plate before exposure or exposure or after exposure. The coding contains a clear information about the destination of the printing plate.
Die jeder Druckplatte zugeordnete Codierung kann als optisch auslesbarer Barcode bzw. Textcode ausgeführt sein. Weiterhin ist es möglich, jeder Druckplatte eine in einem berührungslos auslesbaren RFID-Tag gespeicherte Codierung zuzuordnen. Weiterhin ist es möglich, jede Druckplatte mit Hilfe einer mechanisch auslesbaren Codierung zu versehen, wobei eine derartige mechanisch auslesbare Codierung vorzugsweise als Stanzung der Druckplatte ausgebildet ist.The coding associated with each printing plate can be embodied as a visually readable bar code or text code. Furthermore, it is possible to assign each printing plate a stored in a non-contact readable RFID tag encoding. Furthermore, it is possible to provide each printing plate by means of a mechanically readable coding, wherein such mechanically readable coding is preferably formed as a punching of the printing plate.
Jede belichtete und codierte Druckplatte wird anschließend in den Bereich einer Kassette transportiert. Jede Kassette dient der Aufnahme mehrerer Druckplatten, woraus folgt, dass in den Bereich jeder Kassette mehrere Druckplatten transportiert werden.Each exposed and coded printing plate is then transported into the area of a cassette. Each cassette accommodates a plurality of printing plates, with the result that several printing plates are transported into the area of each cassette.
Zum Transport der Druckplatten in Richtung auf die Kassetten wird vorzugsweise die Codierung der Druckplatten ausgelesen, um abhängig von der Codierung den Transport der Druckplatten in den Bereich der Kassetten zu steuern. Alternativ ist es jedoch auch möglich, die Druckplatten ohne die in der Codierung enthaltene Information in den Bereich der Kassetten zu transportieren.For transporting the printing plates in the direction of the cassettes, the coding of the printing plates is preferably read in order to control the transport of the printing plates into the region of the cassettes, depending on the coding. Alternatively, however, it is also possible to transport the printing plates into the area of the cassettes without the information contained in the coding.
Nach dem Transport der Druckplatten in den Bereich der jeweiligen Kassette wird im Bereich jeder Kassette die Codierung der Druckplatten, die sich im Bereich der jeweiligen Kassette befinden, ausgelesen. Abhängig von der Codierung erfolgt das Auslesen derselben z. B. optisch, über Radiowellen oder mechanisch.After transporting the printing plates in the area of the respective cassette, the coding of the printing plates, which are located in the area of the respective cassette, is read out in the area of each cassette. Depending on the coding, the reading of the same z. As optical, radio waves or mechanical.
Beim Auslesen der Codierungen der Druckplatten wird überprüft, ob sich die Druckplatten an der richtigen Kassette befinden. Dann, wenn festgestellt wird, dass sich eine Druckplatte an einer falschen Kassette befindet, wird eine Fehlermeldung generiert. Wird hingegen festgestellt, dass sich eine Druckplatte an der richtigen Kassette befindet, so wird anschließend für die jeweilige Druckplatte in der Kassette eine definierte Aufnahmeposition freigegeben und die Druckplatte an dieser bzw. in dieser Aufnahmeposition innerhalb der Kassette positioniert.When reading out the codings of the printing plates, it is checked whether the printing plates are on the correct cassette. Then, when it is determined that a printing plate is on a wrong cartridge, an error message is generated. If, on the other hand, it is determined that a printing plate is located on the correct cassette, then a defined receiving position is released for the respective printing plate in the cassette and the printing plate is positioned at this or in this receiving position within the cassette.
Sämtliche in den Bereich einer Kassette transportierte Druckplatten werden sequenziell, d. h. nacheinander, im Sinne des Auslesens der Codierung, der Überprüfung der Codierung, des Freigebens der Aufnahmepositionen sowie des Positionierens derselben in der jeweiligen Aufnahmeposition gehandhabt. Nur dann, wenn die Handhabung einer Druckplatte abgeschlossen ist, wird mit der Handhabung einer anderen Druckplatte begonnen. Die Druckplatten werden demnach nacheinander in die entsprechenden Aufnahmepositionen der jeweiligen Kassetten eingeführt.All printing plates transported in the area of a cassette are sequentially, i. H. successively, in the sense of reading out the coding, checking the coding, releasing the recording positions and positioning them in the respective recording position. Only then, when the handling of a printing plate is completed, the handling of another printing plate is started. The printing plates are thus successively inserted into the respective receiving positions of the respective cassettes.
Das Freigeben der Aufnahmepositionen der Kassetten erfolgt vorzugsweise dadurch, dass an der Kassette eine der jeweiligen Aufnahmeposition zugeordnete Klappe bzw. ein Riegel freigegeben wird.The release of the receiving positions of the cassettes preferably takes place in that a flap assigned to the respective receiving position or a latch is released on the cassette.
Erst nach dem Freigeben der Klappe bzw. des Riegels auf Grundlage des Auslesens der Codierung einer Druckplatte kann eine Druckplatte in eine Aufnahmeposition einer Kassette eingeführt werden.Only after the release of the flap or the bolt based on the reading of the encoding of a printing plate, a printing plate can be inserted into a receiving position of a cassette.
Vorzugsweise wird das Einführen der Druckplatten in die Aufnahmepositionen der Kassetten überwacht, um so festzustellen, dass eine Druckplatte tatsächlich in die richtige Aufnahmeposition gelangt und vollständig in dieselbe eingeführt wird. Sollte hierbei festgestellt werden, dass eine Druckplatte in eine falsche Aufnahmeposition gelangt, oder eine Druckplatte nicht vollständig in die Aufnahmeposition eingeführt wird, so wird vorzugsweise eine Fehlermeldung generiert.Preferably, the insertion of the printing plates into the receiving positions of the cassettes is monitored so as to detect that a printing plate actually comes into the correct picking position and is completely inserted therein. Should it be determined that a pressure plate is getting into the wrong picking position, or a pressure plate is not being fully inserted into the picking position, an error message is preferably generated.
Beim Einführen von Druckplatten in die Aufnahmepositionen der Kassetten können die Druckplatten weiterhin auf Beschädigungen überprüft werden, um so sicherzustellen, dass nur unbeschädigte Druckplatten in Kassetten gelangen und zum Druckplattenwechsel verwendet werden. Weiterhin kann beim Einführen der Druckplatten in die Aufnahmeposition der Kassetten überwacht werden, dass die Druckplatten in der richtigen Orientierung, also weder unter Vertauschen eines Vorlaufendes und eines Nachlaufendes der Druckplatte noch unter Vertauschen einer Vorderseite sowie Rückseite der Druckplatte in die Aufnahmeposition einer Kassette gelangen.When inserting printing plates into the cassette receiving positions, the plates can continue to be inspected for damage, ensuring that only undamaged plates enter cassettes and are used to change the printing plate. Furthermore, it can be monitored during insertion of the printing plates in the receiving position of the cassettes that the printing plates in the correct orientation, so neither interchanging a leading end and a trailing end of the printing plate still get under swapping a front and back of the printing plate in the receiving position of a cassette.
Sämtliche Schritte des erfindungsgemäßen Verfahrens können automatisch durchgeführt werden. So können die Codierungen auf die Druckplatten automatisch aufgebracht werden. Weiterhin kann der Transport der Druckplatten zu den Kassetten automatisch erfolgen. Auch das Auslesen der Codierungen der Druckplatten im Bereich der Kassetten, das Überprüfen der Codierungen sowie das Freigeben der Aufnahmepositionen und das Einführen der Druckplatten in die Aufnahmepositionen der Kassetten kann automatisch durchgeführt werden. Hierdurch ist es möglich, durch manuelle Fehlbedienungen verursachte Fehlbelegungen von Druckplatten beim Druckplattenwechsel auszuschließen.All steps of the method according to the invention can be carried out automatically. Thus, the codings can be applied automatically to the printing plates. Furthermore, the transport of the printing plates to the cassettes can be done automatically. Also, the reading of the codes of the printing plates in the area of the cassettes, the checking of the codes as well as the release of the receiving positions and the insertion of the printing plates in the receiving positions of the cassettes can be carried out automatically. This makes it possible to exclude errors caused by manual incorrect operation of printing plates when changing the printing plate.
