Description
Die Erfindung betrifft eine Vorrichtung zum Führen von Bogen in einer bogenverarbeitenden Maschine mit einem Anlegtisch und an der Vorderkante des Anlegtischs vorgesehenen, aus Vorder- und Deckmarken bestehenden Anlegmarken sowie im Anlegtisch angeordneten, Blasluft in Bogenlaufrichtung zwischen den Anlegtisch und die Bogenunterseite führenden Blasdüsen.The invention relates to a device for guiding sheets in a sheet processing Machine with a feed table and provided at the front edge of the feed table Front and cover marks existing feed marks and arranged in the feed table, Blowing air in the direction of sheet travel leading between the feed table and the underside of the sheet Nozzles.
Eine derartige Vorrichtung ist aus der DE 11 86 473 bekannt, bei der im Raum zwischen den Seitenziehmarken und den Anlegmarken aus Aussparungen zwischen einer Deckleiste und dem Anlegtisch Blasluft in Bogenlaufrichtung geleitet wird.Such a device is known from DE 11 86 473, in which in the space between the Side pull marks and the contact marks from recesses between a cover strip and the feed table blowing air is directed in the direction of sheet travel.
Nachteilig ist, daß durch den aus den Aussparungen austretenden Blasluftstrom im Bereich unmittelbar nach den Aussparungen ein statischer Unterdruck zur Strömungsrichtung aufgebaut wird, der Ursache einer Injektorwirkung ist, die die Bogen großflächig gegen den Anlegtisch führt, so daß es zu einer den Bogenlauf nachteilig beeinflussenden Haftung auf dem Anlegtisch kommen kann.It is disadvantageous that the blown air stream emerging from the cutouts in the area A static negative pressure to the flow direction is built up immediately after the cutouts is the cause of an injector effect, which spreads the sheet against the feed table leads, so that it leads to a disadvantageous influence on the sheet travel liability on the Feed table can come.
Weiterhin ist aus dem DE-G'M 82 25 956 eine derartige Vorrichtung bekannt, bei der zur Erzeugung eines Blasluftstromes in der Bogentransportebene Düsen vorgesehen sind, die mit mindestens zwei getrennten, gegenüber der Transportebene unterschiedlich geneigten Düsenkanälen versehen sind. Damit soll der Volumenstrom des Blasstrahls erhöht und ein nachteiliges Haften der Bogen am Anlegtisch verhindert werden.Furthermore, such a device is known from DE-G'M 82 25 956, in which for Generation of a blown air flow in the sheet transport plane nozzles are provided with at least two separate, differently inclined to the transport level Nozzle channels are provided. The volume flow of the blowing jet should thus increase and decrease disadvantageous adhesion of the sheets to the feed table can be prevented.
Nachteilig ist jedoch, daß durch den zusätzlichen Düsenkanal ein zusätzlicher Impuls auf die Bogen übertragen wird, was bei labilen Bogen zu einem den Bogenlauf nachteilig beeinflussenden Flattern kommen kann.The disadvantage, however, is that the additional nozzle channel gives an additional impulse to the Sheet is transferred, which in the case of unstable sheets adversely affects sheet travel Flutter can come.
Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, die es ermöglicht, einen störungsfreien Bogentransport im Bereich des Anlegtisches zu realisieren.The object of the invention is to provide a device which enables trouble-free Realize sheet transport in the area of the feed table.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of
Durch die erfindungsgemäße Lösung wird mit einfachen Mitteln sichergestellt, daß einerseits die zur Verarbeitung gelangenden Bogen gegen den Anlegtisch und ihre Vorderkante unter die Deckmarken gegen die Vordermarken geführt werden, andererseits wird vermieden, daß die Bogen auf den Anlegtisch haften oder den Bogenlauf in ebenfalls nachteiliger Weise durch Flattern beeinflussen.The solution according to the invention ensures with simple means that, on the one hand the sheets for processing against the feed table and their leading edge under the cover marks are guided against the front marks, on the other hand it is avoided that the sheets stick to the feed table or the sheet run also disadvantageously influenced by flutter.

In Figur 1 ist ausschnittsweise ein Anlegtisch 4 mit im Abstand zueinander und über die
Breite des Anlegtisch 4 verteilt angeordneten Strömungskanälen 9 dargestellt. Die Strömungskanäle
9 verlaufen geneigt zur Bogenlaufrichtung 10, wobei die Strömungskanäle 9
schräg nach außen gerichtet sind. Jedem Strömungskanal 9 ist eine Blasdüse 1 zugeordnet,
die mittels eines oder mehrerer über die Breite des Anlegtischs verteilt angeordneter Druckkammern
5 mit Blasluft versorgt werden. Die Druckkammern 5 und die Blasdüsen 1 sind mit
einem Deckblech 7 abgedeckt, was mit der Oberfläche des Anlegtischs 4 eine Ebene bildet.
Unmittelbar den Öffnungen 1.1 der Blasdüsen 1 sind in den Strömungskanälen 9 jeweils eine
Saugbohrung 6 vorgesehen, die in Verbindung zum atmosphärischen Umgebungsdruck
steht. Durch die Zuordnung dieser Saugbohrungen 6 unmittelbar zu den Öffnungen 1.1 der
Blasdüsen 1, wobei die Saugbohrungen 6 etwa senkrecht zum Blasstrahl 2 verlaufen, entsteht
ein Injektor und der im Austrittsbereich des Blasstrahls 2 sich üblicherweise aufbauende
statische Unterdruck wird reduziert, so daß durch Erhöhung des Volumenstromes des
Blasstrahls 2 und Verminderung der Injektorwirkung zwischen der Unterseite der Bogen 3
und Anlegtisch 4 ein großflächiges Haften der Bogen 3 auf dem Anlegtisch 4 vermieden wird.
Damit können die in Bogenlaufrichtung 8 zum Anlegtisch 4 geförderten Bogen 3 störungsfrei
an nicht dargestellte, aus Vorder- und Deckmarken bestehende Anlegmarken geführt werden. In Figure 1 is a section of a feed table 4 with a distance from each other and over the
