Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung nach dem Oberbegriff des Anspruchs 1 bzw. des Anspruchs 3.The invention relates to a method and a device according to the preamble of claim 1 and the Claim 3.
Es ist bekannt, auf einer bewegten Druckbahn in vorgegebenen Abständen vorgesehene Druckmarken mittels eines lichtempfindlichen Sensors abzutasten, um Informationen über die Lage der Druckbahn beim Bedrucken zu erhalten. Der Sensor, beispielsweise eine Fotodiode, kann hierbei relativ klein ausgebildet sein, jedoch muss die Druckmarke eine gewisse Größe aufweisen, damit sie vom Sensor zuverlässig erfasst wird. Die Größe der Druckmarken kann aber das Druckbild beeinträchtigen, weswegen man daran interessiert ist, die Druckmarke möglichst klein zu machen.It is known to be moving Print web at predetermined intervals intended printing marks by means of a light-sensitive sensor to scan for information about to maintain the position of the printing path when printing. The sensor, for example a photodiode, can be made relatively small, however the print mark must have a certain size so that it Sensor reliable is recorded. The size of the print marks but can affect the printed image, which is why one is interested in making the print mark as small as possible.
Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung der eingangs angegebenen Art so auszubilden, dass auch bei kleinen Druckmarken eine zuverlässige Abtastung möglich ist.The object of the invention is a To design methods and a device of the type specified at the outset that reliable scanning is possible even with small print marks.
Dies wird erfindungsgemäß durch die Merkmale im kennzeichnenden Teil der Ansprüche 1 und 3 erreicht. Dadurch, dass dieselbe Druckmarke wiederholt durch schräg zur Bahnlaufrichtung liegende, strichförmige Sensorelemente abgetastet und das Verhältnis der Durchlaufzeiten der Druckmarke zwischen den einzelnen Abtastvorgängen in Beziehung zueinander gesetzt wird, kann eine Information über die Seitenlage der Druckmarke erhalten werden, auch wenn diese sehr klein ausgebildet ist.This is done according to the invention the features in the characterizing part of claims 1 and 3 achieved. Thereby, that the same print mark is repeated by line-shaped sensor elements lying at an angle to the web running direction sampled and the ratio the throughput times of the print mark between the individual scanning processes in Relation to each other can provide information about the Lateral position of the print mark can be obtained, even if this is very is small.

Nach einer weiteren Ausgestaltung kann ein flaches Bündel aus Lichtleitfasern vorgesehen werden, um ein strichförmiges Sensorelement auszubilden. Hierbei bildet die eine Stirnseite des flachen Bündels aus Lichtleitfasern das strichförmige Sensorelement, während das gegenüberliegende Ende des Bündels zu einer Fotodiode führt.According to a further embodiment can be a flat bundle of optical fibers are provided to a line-shaped sensor element train. Here forms one end face of the flat bundle Optical fibers the line-shaped Sensor element while the opposite End of bundle leads to a photodiode.
