Abstract
Description
Die Erfindung betrifft ein Verfahren zum Ausrichten von Bogen in einer Bogen verarbeitenden Maschine nach dem Oberbegriff des 1. Anspruchs und eine Vorrichtung hierfür nach dem Oberbegriff des 11. Anspruchs.The invention relates to a method for aligning sheets in a sheet-processing machine according to the preamble of the first claim and an apparatus therefor according to the preamble of the 11th claim.
Aus der
Bei dieser Einrichtung ist lediglich eine geschwindigkeitsoptimierte Bogenzuführung möglich. Zuführfehler werden nicht ausgeglichen. Nur in Verbindung mit einem Bogenankunftssensor an den Vordermarken könnte auf Fehler in Bezug auf die Phasenlage, also auf die fehlerhafte Lage des Bogens in Bezug auf den Drehwinkel der Druckmaschine, reagiert werden.In this device, only a speed-optimized sheet feeder is possible. Feed errors are not compensated. Only in conjunction with a sheet arrival sensor at the leading brands could be responded to errors in relation to the phase position, so the faulty position of the sheet with respect to the rotation angle of the printing press.
Dabei ist von Nachteil, dass sich der Bogen beim Messvorgang in der Ausrichtlinie befindet. Wird hier ein Fehler detektiert, kann das zu Stoppern führen. Deshalb ist es mit dieser Einrichtung nur möglich, tendenzielle Fehler zu korrigieren.The disadvantage here is that the sheet is in the alignment during the measurement process. If an error is detected here, this can lead to stoppages. Therefore, with this facility, it is only possible to correct biased errors.
In der
Damit wird eine Lösung gezeigt, eine verdeckte Bogenkante noch vor der Anleglinie zu erfassen. Ohne entsprechende Wirkelemente sind diese Einrichtungen ebenfalls auf eine Anwesenheitskontrolle beschränkt.Thus, a solution is shown to detect a hidden arc edge even before the landing line. Without appropriate active elements, these facilities are also limited to attendance control.
In der
Ein Nachteil dabei ist, dass der Sensor, bedingt durch die hohe Zuführungsgeschwindigkeit, einen relativ großen Messbereich besitzen muss. Weiterhin muss das erste Greifersystem zur Vorausrichtung den Gesamtfehler ausgleichen, der sich aus der fehlerhafte Lage der Bogen zum Drehwinkel der Druckmaschine und dem Schieflagefehler des Bogens ergibt.A disadvantage here is that the sensor, due to the high feed rate, must have a relatively large measuring range. Furthermore, the first gripper system for pre-alignment must compensate for the total error resulting from the misalignment of the sheets to the rotational angle of the printing press and the misalignment error of the sheet.
Aus der
Nachteilig an dieser Lösung ist es, dass der Bogen an seiner Anleglinie angehalten und geklemmt wird, was insbesondere bei dünnen Bedruckstoffen zu einer Verwerfung führen kann.The disadvantage of this solution is that the sheet is stopped and clamped at its Anlegglinie, which can lead to a rejection especially for thin substrates.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu entwickeln, durch das die oben genannten Nachteile beseitigt werden.The invention is therefore based on the object to develop a method and an apparatus by which the abovementioned disadvantages are eliminated.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren nach dem 1. Anspruch und eine Vorrichtung nach dem 11. Anspruch gelöst.According to the invention the object is achieved by a method according to the first claim and a device according to the eleventh claim.
Durch die erfindungsgemäße Lösung ist eine dynamische Bogenausrichtung möglich. Der Bogen wird nicht wie in bekannten Einrichtungen an mechanischen Anschlägen ausgerichtet, so dass die mechanische Beanspruchung des Bogens beim Anprall ausgeschlossen werden kann. Dadurch werden Bogenverspannungen vermieden, was eine Leistungssteigerung, besonders bei der Verarbeitung von instabileren Materialien, möglich macht.The inventive solution a dynamic sheet alignment is possible. The arc is not aligned with mechanical stops, as in known devices, so that the mechanical stress of the sheet during impact can be excluded. This will be Avoiding bow tensions, which makes it possible to increase performance, especially when processing less stable materials.
Im Folgenden soll die Erfindung beispielhaft erläutert werden. Die dazugehörigen Zeichnungen stellen dabei dar:In the following, the invention will be explained by way of example. The accompanying drawings represent:
