Abstract

Die Erfindung betrifft eine Tasteinrichtung zum Fixieren eines Bogens unter Druck auf einem Bogenstapel eines Bogenanlegers und eine Überwachungseinrichtung für die Bogenzufuhr von einem Bogenstapel in einem Bogenanleger zu einer Bogen verarbeitenden Maschine, wobei die Stapelhöhe in Bezug auf eine Trenn- und Fördereinrichtung erfasst wird. Zur exakteren Erfassung und Beeinflussung der oberen Stapellage wird die Tasteeinrichtung mittels einer aktiven Feder gebildet. Diese besteht aus einem Verbund eines Federmaterials und eines oder mehrerer Piezoaktuatoren. Mittels der Tasteinrichtung kann ein Andrückmittel gegen den Bogenstapel oder von diesem weg verlagert werden. Außerdem kann mittels der Tasteinrichtung die Stapelhöhe erfasst werden.

The invention relates to a scanning device for fixing a sheet under pressure on a stack of sheets of a sheet feeder and a monitoring device for the sheet feed from a sheet stack in a sheet feeder to a sheet-processing machine, wherein the stack height is detected with respect to a separating and conveying device. For more precise detection and influencing of the upper stack layer, the button device is formed by means of an active spring. This consists of a composite of a spring material and one or more piezo actuators. By means of the sensing device, a pressing means can be displaced against the sheet stack or away from it. In addition, the stack height can be detected by means of the sensing device.
