Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Detektion von Überschießbogen an Anlegern von Bogendruckmaschinen.The The invention relates to a method and a device for detection overdrafts to investors from sheetfed presses.
Auf Schuppenanlegern von Bogendruckmaschinen werden die einzeln von einem Stapel geförderten Bogen in Schuppenformation abgelegt, wobei das Bogenende des jeweils vorhergehenden Bogens über dem Bogenanfang des nachfolgenden Bogens liegt. Die Schuppenformation wird kontinuierlich in Richtung auf eine Anlegelinie gefördert, wobei der jeweils vordere Bogen an vorderen Anschlägen (Vordermarken) ausgerichtet und dann durch seitliches Verschieben an Seitenmarken in eine definierte Einzugsposition gebracht wird, um danach einzeln auf Maschinengeschwindigkeit beschleunigt und in das erste Druckwerk eingezogen zu werden. Insbesondere bei adhäsiven oder elektrostatisch sensiblen Bedruckstoffen, wie z.B. Kunststofffolien oder beschichteten Papieren, kommt es dabei immer wieder zu Problemen beim Vereinzeln der Bogen infolge der Haftung übereinanderliegender Bogen, so dass zwei oder mehrere Bogen übereinander liegen bleiben und nicht vollständig schuppenförmig vereinzelt werden (Bildung von Doppel- oder Mehrfachbogen) oder zum Mitreißen des nachfolgenden, erst in die Vordermarken einlaufenden Bogens mit dem bereits abziehenden, in das erste Druckwerk einlaufenden Bogen (Überschießbogen). In beiden Fällen können durch das gleichzeitige Einziehen mehrerer Bogen in die Druckzone Druckstörungen und Druckmaschinenschäden verursacht werden.On Schuppenanlegern of sheet-fed presses are individually from a stack sponsored Arches filed in dandruff formation, with the end of the bow of each previous arc over the beginning of the bow of the subsequent bow is. The scaly formation is continuously promoted towards a landing line, where each front bow aligned with front stops (front marks) and then by moving laterally to side marks in a defined Feeding position is brought to then individually on machine speed accelerated and fed into the first printing unit. Especially at adhesive or electrostatically sensitive substrates, e.g. Plastic films or coated papers, it always comes back to problems when separating the sheets due to the adhesion of superimposed sheets, so that two or more sheets are on top of each other lie down and not completely imbricated isolated (formation of double or multiple sheets) or to thrill of the following, only in the front marks incoming bow with the already withdrawing, entering the first printing unit Bow (overflow bow). In both cases can by simultaneously feeding several sheets into the print zone pressure disturbances and printing machine damage caused.
Zur Erfassung von Doppel- oder Mehrfachbogen ist es bekannt, Doppelbogenkontrolleinrichtungen (DBK) im Bereich des Schuppenstromes oder der Anlegelinie einzusetzen, die die Bogenzufuhr zur Druckmaschine unterbrechen, sobald ein Doppel- oder Mehrfachbogen detektiert wird.to Detection of double or multiple sheets is known, double sheet control devices (DBK) in the area of the shingled stream or the laying line, which interrupt the sheet feed to the printing press, as soon as a double or Multiple arc is detected.

Die Aufgabe der Erfindung besteht darin, ein weiteres Verfahren und eine Vorrichtung zur Detektion von Überschießbogen anzugeben, die mit geringem wirtschaftlichen Aufwand realisierbar sind.The The object of the invention is a further method and to provide a device for the detection of Überschussbogen that with low economic effort can be realized.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des ersten oder zweiten Anspruchs gelöst.According to the invention Problem solved by the features of the first or second claim.
Die Erfindung hat den Vorteil, dass das Verfahren mit einfachen Mitteln realisierbar ist und keine bedruckstoffabhängige Kalibrierung erfordert.The Invention has the advantage that the method with simple means can be realized and requires no substrate-dependent calibration.
Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Die dazugehörigen Zeichnungen zeigen inThe Invention is intended to an embodiment be explained in more detail. The accompanying drawings show in
