Abstract

Die Erfindung bezieht sich auf einen Bogenanleger zum in einem Arbeitstakt vereinzelten Zuführen von Bogen zu einer Weiterfördereinrichtung. Diese weist ein den jeweils obersten Bogen eines Bogenstapels 1 in dessen in Förderrichtung 2 hinteren Bereich erfassendes und etwa senkrecht zu Schleppsaugern 8 anhebendes Trennelement auf, wobei der angehobene Bogen 9 an seiner nach oben gerichteten Fläche von den Schleppsaugern 8 erfaßbar und in gestreckter Ausrichtung etwa parallel zur Stapeloberfläche 5 in Förderrichtung 2 der Weitertransporteinrichtung zuführbar ist. Weiterhin ist ein Drückerfuß 3 vorhanden, der während der Weiterförderung des Bogens 9 durch die Schleppsauger 8 über dem hinteren Bereich des Bogenstapels 1 nach unten auf diesen zubewegbar ist. Das Trennelement ist der Drückerfuß 3, der im Arbeitstakt etwa senkrecht zwischen einer stapeloberflächennahen und einer angehobenen Position bewegbar antreibbar ist und eine etwa parallel zur Stapeloberfläche 5 in Weiterförderrichtung 2 gerichtete Düse 4 aufweist, die während des Bewegungswegs von der stapeloberflächennahen Position zur angehobenen Position mit Druckluft beaufschlagbar und die oberhalb ihrer Luftaustrittsöffnung 6 eine sich in Weiterförderrichtung 2 erstreckende Anströmfläche 15 besitzt.

The invention relates to a sheet feeder for feeding sheets to a further conveying device in a single work cycle. This has a separating element which detects the uppermost sheet of a sheet stack 1 in its rear area in the conveying direction 2 and is lifted approximately perpendicular to suction cups 8, the lifted sheet 9 being detectable by the suction cups 8 on its upward-facing surface and approximately parallel in the stretched orientation can be fed to the stacking surface 5 in the conveying direction 2 of the further transport device. Furthermore, a presser foot 3 is provided, which can be moved downward towards the stack of sheets 1 while the sheet 9 is being conveyed by the suction cups 8. The separating element is the presser foot 3, which can be driven in the work cycle approximately vertically between a position close to the stack surface and a raised position and has a nozzle 4 directed approximately parallel to the stack surface 5 in the conveying direction 2, which with compressed air during the movement path from the position close to the stack surface to the raised position acted upon and which has an inflow surface 15 extending above its air outlet opening 6 in the direction of further conveyance 2.
