Abstract
Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Detektion der Lage einer Druckplatte auf einer Auflagefläche in einer durch ein Anlegemittel vorbestimmten Position mit mindestens einem Detektor, der in der vorbestimmten Position ein Detektionssignal generiert und an eine Auswerteeinheit übermittelt.The The invention relates to an apparatus and a method for detection the location of a printing plate on a support surface in a by a contact means predetermined position with at least one detector in the predetermined position generates a detection signal and to a Evaluation unit transmitted.
Nach dem Stand der Technik in der Reproduktionstechnik wird für die Herstellung einer Druckseite mit Bild, Text und Grafik eine Druckvorlage elektronisch erzeugt und in verschiedenen Technologien auf die Druckplatte übertragen, die wiederum, aufgezogen auf einen Plattenzylinder in einer Druckmaschine, das Druckbild in verschiedenen Technologien auf den Druckbogen überträgt. Unabhängig von den verschiedenen Technologien der Druckplatteherstellung und des Druckprozesses ist es in jedem Falle erforderlich, die Druckplatte beim Positionieren in der Herstellungsvorrichtung sowie beim Druckprozess auf dem Plattenzylinder konform auf der Auflagefläche auszurichten. Dies ist insbesondere wichtig, wenn beim Mehrfarbendruck das Druckbild aus mehreren deckungsgleich übereinander zu druckender Farbauszügen mittels verschiedener Druckplatten für die jeweiligen Farbauszügen zu erstellen ist. Zur genauen Ausrichtung der Druckplatte sind in festliegendem Bezug zu den Seitenkanten der Druckplatte oder zu Registermarken auf der Druckplatte Ausstanzungen an der in Positionierungsrichtung vorderen Kante der Druckplatte vorgesehen, die beim Positionieren der Druckplatte gegen Passstifte in den jeweiligen Vorrichtungen angelagert werden. Die Lage des Druckbildes bei der Druckplatteherstellung ist wiederum in Bezug zu den Seitenkanten oder den Registermarken der Druckplatte festgelegt. Zur Kontrolle der korrekten Ausrichtung der meist automatisch erfolgten Positionierung der Druckplatte auf der jeweiligen Auflagefläche sind verschiedene Detektionsvorrichtungen bekannt, die eine Fehllage der Druckplatte signalisieren.To The state of the art in reproduction technology is used for the production a print page with image, text and graphics a print template electronically generated and transferred to the printing plate in various technologies, which in turn, mounted on a plate cylinder in a printing machine, transfers the printed image in different technologies to the printed sheet. Independent of the various technologies of printing plate making and the Printing process, it is necessary in any case, the printing plate when positioning in the manufacturing device as well as the printing process align the plate cylinder conforming to the support surface. This is especially important if in multi-color printing the printed image several congruent one above the other to be printed color separations to create using different printing plates for the respective color separations is. For exact alignment of the printing plate are in fixed Reference to the side edges of the printing plate or register marks on the pressure plate punched on the in the direction of positioning provided at the front edge of the pressure plate when positioning the pressure plate against dowel pins in the respective devices be attached. The position of the print image during the printing plate production is in turn related to the side edges or register marks the pressure plate set. To check the correct alignment the most automatic positioning of the printing plate the respective bearing surface Various detection devices are known which cause misplacement signal the pressure plate.

Kontaktprobleme ergeben sich auch aus der Notwendigkeit von Tolleranzen der Ausstanzungen gegenüber den Passstiften, sowie der seitlichen Führungen gegenüber der Druckplattenseitenkanten, damit die Druckplatte ohne zu Verklemmen leicht verschiebbar und leicht anlegbar ist. Bei bereits geringem seitlichem Versatz der Druckplatte, kann der Kontakt der Anlagedetektoren mit dem Bodenbereich der Ausstanzung wegen der auf kleinem Umfangswinkel begrenzten Kontaktfläche ausbleiben, obwohl die Vorderkante der Druckplatte in ausreichender Genauigkeit ausgerichtet ist.Contact problems also arise from the need for Tolleranzen the punched out against the dowel pins, as well as the lateral Füh ments with respect to the pressure plate side edges, so that the pressure plate is easy to move without jamming and easy to apply. With only a slight lateral offset of the pressure plate, the contact of the system detectors with the bottom portion of the punch can be omitted because of limited contact area on a small circumferential angle, although the leading edge of the printing plate is aligned with sufficient accuracy.

Nachteilig an dieser Lösung ist, dass zum einen die Fertigung solcher kontaktreichen Passelemente sehr kompliziert und kostenintensiv ist, da in den isoliert ausgeführten Grundkörper des Passelementes mehrere passgerechte Ausnehmungen für die einzelnen Sensorelemente vorgefertigt sein müssen, in die die Sensorelemente mit ihrer Kontaktfläche und den Verbindungsleitungen sorgfältig eingebracht und befestigt werden müssen. Geringe Maßabweichungen in der Lage der seitlichen Kontaktflächen zur übrigen Umfangsfläche des Passelementes führen zu inhomogenen Übergängen in der Umfangsfläche der Passelemente, die nachträglich kaum zu beheben sind. Ergeben sich Spalten oder Senken, tragen sich dort kontaktbehindernde Verschmutzungen ab. Überstände und scharfkantige Vorsprünge an der Umfangsfläche behindern das Eingleiten der Passelemente in die Registerausnehmungen der Druckplatte und führen im ungünstigsten Fall zum „Hängen bleiben" der Druckplatte oder zu Beschädigung der Ausstanzung. Zudem werden auch mit dieser Lösung die im Übrigen genannten Kontaktprobleme nicht zuverlässig behoben.adversely at this solution is that on the one hand the production of such contact-rich fitting elements is very complicated and costly because in the isolated running body of the Passelementes several passgerechte recesses for each Sensor elements must be prefabricated, in which the sensor elements with their contact surface and the connecting lines carefully inserted and fixed Need to become. Small deviations in the position of the lateral contact surfaces with the remaining peripheral surface of the Pass element to inhomogeneous transitions in the peripheral surface the mating elements, which hardly afterwards to fix. If there are gaps or depressions, they are there contact-hindering dirt. Overhangs and sharp-edged projections on the peripheral surface hinder the sliding of the fitting elements into the register recesses the pressure plate and lead in the worst case to "hang" the pressure plate or damage the punching. In addition, with this solution, the otherwise mentioned contact problems not reliable Fixed.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur Detektion der Lage einer Druckplatte derart weiter zu bilden, dass mit geringem Aufwand eine zuverlässigere Detektion der Lage der Druckplatte erreicht wird.Of the Invention is therefore based on the object, a device and a method for detecting the position of a printing plate so on to form that with little effort a more reliable detection of the situation the pressure plate is reached.
Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des 1. Anspruchs und durch ein Verfahren mit den Merkmalen des 16. Anspruches gelöst.According to the invention Task by a device having the features of the first claim and solved by a method having the features of the 16th claim.
Die Erfindung hat den Vorteil, dass mit einfachen Mitteln eine sichere und störungsfreie Detektion der Lage der Druckplatten auf einer Auflagefläche möglich ist.The Invention has the advantage that with simple means a safe and trouble-free Detection of the position of the printing plates on a support surface is possible.
