Wird ein Bogen nicht auf einem ersten Bogenstapel ausgelegt, so besteht die Gefahr, dass der Bogen bei seinem Weitertransport einen auf diesem Bogenstapel befindlichen obersten Stapel berührt und diesen aufgrund der Relativbewegung beschädigt, zum Beispiel zerkratzt. Wird ein Bogen überhaupt nicht abgestapelt, sondern zur nachfolgenden Begutachtung weiter transportiert, so kann dieses Problem ebenfalls auftreten, dann auf den obersten Bogen beider Stapel.

Aufgabe der vorliegenden Erfindung ist es, einen Ausleger einer Bogendruckmaschine zu schaffen, bei welchem mit kostengünstigen, einfach anzusteuernden und effektiv wirksamen Mitteln eine Beschädigung vom obersten Bogen eines Stapels verhindert wird, wenn ein Bogen über den Stapel hinweg weiter transportiert wird.The object of the present invention is to provide a boom of a sheet-fed printing machine in which damage is prevented from the topmost sheet of a stack with inexpensive, easy-to-control and effective means when a sheet is transported across the stack.
Gelöst wird diese Aufgabe durch einen Ausleger einer Bogendruckmaschine mit den Merkmalen von Anspruch 1.This object is achieved by a boom of a sheet-fed printing machine having the features of
Der erfindungsgemäße Ausleger einer Bogendruckmaschine besitzt einen Bogenstapel zum Ablegen von Bogen, ein Transportsystem zum Zuführen von Bogen in einer Bogentransportrichtung in einer Transportebene und ein stromabwärtig des Bogenstapels angeordnetes Transportmittel zum Weitertransport von Bogen, die nicht auf dem Bogenstapel abgelegt werden. Der Weitertransport erfolgt in eine nachfolgende Station. Erfindungsgemäß ist zwischen dem Bogenstapel und der Transportebene eine Blaseinrichtung angeordnet zum Leiten der Bogen, d. h. auf einer Höhe, welche zwischen dem obersten Bogen des Bogenstapels und der Transportebene liegt. So wird verhindert, dass ein transportierter Bogen auf dem obersten Bogen des Bogenstapels schleift und diesen womöglich beschädigt.
Weiterhin ist es vorgesehen, dass die Blaseinrichtung - in Bogentransportrichtung gesehen nach, d. h. - stromabwärtig des Bogenstapels und angrenzend an die Bogenstapelvorderkante angeordnet und insbesondere am Maschinengestell des Auslegers befestigt ist. Die Blaseinrichtung befindet sich somit - in Maschinenlaufrichtung gesehen - zwischen dem Bogenstapel und dem Transportmittel.
Ein solcher Ausleger hat den Vorteil, dass ein Bogen, auch bei hoher Geschwindigkeit, sicher geführt werden kann. Auch kann die Blaseinrichtung schnell abgeschaltet bzw. umgeschaltet werden, so dass eine Anpassung an die tatsächlich vorliegenden Erfordernisse der Bogenführung ermöglicht wird.The boom of a sheet-fed printing machine according to the invention has a sheet stack for depositing sheets, a transport system for feeding sheets in a sheet transport direction in a transport plane and downstream of the sheet stack arranged transport means for further transport of sheets that are not stored on the sheet stack. The further transport takes place in a subsequent station. According to the invention, a blowing device is arranged between the sheet stack and the transport plane for guiding the sheets, ie at a height which lies between the uppermost sheet of the sheet stack and the transport plane. This prevents a transported sheet from dragging on the top sheet of the sheet pile and possibly damaging it.
Furthermore, it is provided that the blowing device - as seen in the sheet transport direction, ie - downstream of the sheet stack and adjacent to the sheet stack leading edge is arranged and in particular attached to the machine frame of the boom. The blowing device is thus - seen in the machine direction - between the sheet stack and the transport.
Such a boom has the advantage that a bow, even at high speed, can be performed safely. Also, the blowing device can be quickly switched off or switched so that an adaptation to the actual requirements of the bowing is made possible.
In einer besonders vorteilhaften und daher bevorzugten Weiterbildung des erfindungsgemäßen Auslegers ist durch die Blaseinrichtung ein zum Transportmittel weiter bewegter Bogen von unten anblasbar, d. h. ein Bogen, welcher nicht auf dem Bogenstapel abgelegt wird, kann von der unterhalb der Transportebene angeordneten Blaseinrichtung angeblasen werden. Als besonders vorteilhaft wird es angesehen, wenn die Blaseinrichtung eine Blasluft bereitstellt, welche im Wesentlichen entgegen der Bogentransportrichtung ausgerichtet ist. D.h. die Blasluft ist entgegen der Bogentransportrichtung orientiert und es gibt immer eine Komponente welche entgegen der Bogentransportrichtung wirkt. Dadurch kann ein stabiler Bogenlauf ohne Flattern der Bogen erreicht werden. Zusätzlich kann die Blasluft eine Komponente besitzen, welche von unten nach oben wirkt, sodass sich eine schräge Ausrichtung der Blasluft ergibt.In a particularly advantageous and therefore preferred embodiment of the boom according to the invention by the blowing device for moving further moving sheet from below inflatable, ie a sheet which is not stored on the sheet stack can be blown by the arranged below the transport plane blowing device. It is considered to be particularly advantageous if the blowing device provides a blown air, which is aligned substantially opposite to the sheet transport direction. That is, the blowing air is oriented counter to the sheet transport direction and there is always a component which acts counter to the sheet transport direction. This allows a stable sheet travel without flapping the sheet can be achieved. In addition, the Blow air have a component which acts from bottom to top, so that there is an oblique orientation of the blown air.

Die Bogen 1000 werden von einem Transportsystem 10 in einer Transportebene E in einer Bogentransportrichtung T zum Ausleger 100 transportiert. Dazu sind an umlaufenden Ketten 11 Greifer 12 vorgesehen.The
Im Ausleger 100 kann ein jeweiliger Bogen 1000 entweder auf einen Bogenstapel 1003 abgelegt werden, wobei der oberste Bogen des Bogenstapels 1003 mit dem Bezugszeichen 1001 versehen ist. Alternativ kann der Bogen 1000 über den Bogenstapel 1003 hinweg in Transportrichtung T weiter transportiert werden zu einem Transportmittel 13, welches hier als umlaufendes Transportband oder Transportbandpaar ausgeführt ist.

Die Steuereinheit 17 kann über einen Speicher 18 verfügen, in welchem Druckkennlinien hinterlegt sind, wobei die Druckkennlinien, z. B. abhängig von der Grammatur sowie der Bearbeitungsgeschwindigkeit, den zeitlichen Verlauf sowie die Stärke des Blasluftstrahls festlegen. Von der Steuereinheit 17 werden Blaslufterzeuger 16 und Ventil 15 entsprechend angesteuert.The
Oberhalb des Bogenstapels 1003 können zusätzlich Blasrohre 20 angeordnet sein, welche eine nach unten in Richtung des Bogenstapels 1003 gerichtete Blasluft bereitstellen. Diese Blasluft unterstützt das Ablegen eines Bogens 1001. Die Blasluft der Blasrohre wird nur dann aktiviert, wenn an der Blaseinrichtung 14 keinen Blasluft b bereitgestellt wird und umgekehrt. Die Blasluft für die Blasrohre 20 kann ebenfalls vom Blaslufterzeuger 16 zur Verfügung gestellt werden. Und die Ansteuerung eines Ventils zwischen Blasrohren 20 und Blaslufterzeuger 16 kann ebenfalls durch die Steuereinheit 17 erfolgen.
Von der Steuereinheit 17 können auch die Dreiwegeweiche 19 sowie ein Antrieb des Transportmittels 13 angesteuert werden.Above the
