Hierbei können die Leitflächen eine unterschiedliche, dem jeweiligen Luftbedarf angepaßte Flächenbelegung mit Düsen aufweisen. Die Luftversorgung der Düsen erfolgt über Ventilatoren, deren Drehzahl zur Einstellung der Schwebeführung im Blasbetrieb und zur Anpassung der Reibkraft des Bogens auf den Leitflächen im Saugbetrieb regelbar ist. Zur Umsteuerung von Blasbetrieb auf Saugbetrieb können außerdem die Ventilatoren in ihrer Drehrichtung umschaltbar sein.In a sheet guiding device known from EP 0 725 025 B1 of the specified type in the sheet transport direction seen in the inlet area of a guide surface arranged nozzles depending on the processed Printing material optionally with suction air or with blown air acted upon and the nozzles between the inlet area and the outlet area of the guide surface arranged guide zone are blown with air, at least some of the nozzles blow the air essentially tangentially to the surface of the guide surface. Here, the Guiding surfaces a different, the respective air requirement have adapted area coverage with nozzles.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Anstellwinkel zumindest einzelner Düsen gegenüber der Leitfläche einstellbar ist. Zusätzlich kann auch die Größe des Durchtrittsquerschnitts zumindest einzelner Düsen einstellbar sein. Die Erfindung ermöglicht eine zonenweise individuelle Einstellung des Blasluftstroms und damit eine optimale Anpassung der Bogenführung an die jeweils gegebenen Betriebssituationen, ohne daß es einer Vielzahl von Ventilatoren mit regelbarer Drehzahl bedarf.According to the invention this object is achieved in that the Angle of attack of at least individual nozzles relative to the guide surface is adjustable. In addition, the size of the Passage cross section adjustable at least individual nozzles his. The invention enables a zone-by-zone individual Adjustment of the blown air flow and thus an optimal one Adjustment of the arch guidance to the given one Operating situations without having a large number of fans with adjustable speed required.
Gemäß einer besonders einfachen und vorteilhaften Ausgestaltung der Erfindung können die Düsen durch eine schlitzförmige Öffnung in einer die Leitfläche bildenden Wand und mindestens jeweils eine in der Öffnung angeordnete Lamelle gebildet sein, wobei die Lamelle in einem Winkel zur Leitfläche angestellt ist. Der Anstellwinkel der Lamelle kann zudem verstellbar sein. Mit dieser erfindungsgemäßen Ausbildung der Düsen läßt sich die Richtung des Blasluftstroms und gleichzeitig der Durchtrittsquerschnitt auf einfache Weise variieren und damit der Blasdruck sowie die Ausbildung und Lage von die Bogen führenden Luftpolstern an die Erfordernisse der Bogenführung optimal anpassen. Besonders vorteilhaft ist eine Ausgestaltung, bei der die Lamellen eine konvex gekrümmte Luftleitfläche haben, durch die die an den Lamellen entlangströmende Luft in eine zur Leitfläche parallele Strömungsrichtung umlenkbar ist. Die konvex gekrümmte Luftleitfläche kann lediglich auf einer oder auf beiden Seiten der Lamelle ausgebildet sein. Im letzteren Fall kann bei entsprechender Verstellung des Anstellwinkels der Lamellen der Luftstrom auch in der entgegengesetzten Richtung parallel zur Leitfläche gelenkt werden. Zur zonenweisen Anpassung der Blas- oder Saugluft an die Erfordernisse der Bogenführung kann außerdem die Verteilung der schlitzförmigen Öffnungen über die Leitfläche ungleichmäßig sein.According to a particularly simple and advantageous embodiment According to the invention, the nozzles can be slit-shaped Opening in a wall forming the guide surface and at least one lamella arranged in the opening be formed, the lamella at an angle to the guide surface is employed. The angle of attack of the slat can also be adjustable.

Die in Figur 1 schematisch dargestellte Druckmaschine weist
mehrere in Reihe angeordnete Druckwerke 1 auf, von denen
jeweils der Plattenzylinder 2, der Gummituchzylinder 3 und
der doppelt große Druckzylinder 4 wiedergegeben sind. Zwischen
den Druckwerken erfolgt der Transport der Bogen
jeweils über Transfertrommeln 5 oder wenn eine Möglichkeit
zur Bogenwendung besteht über eine Wendetrommel 6. Vom
Druckzylinder des letzten Druckwerks werden die Bogen durch
ein Kettengreifersystem 7 eines Auslegers 8 zu einem Auslegerstapel
9 transportiert. An den Transfertrommeln 5, der
Wendetrommel 6 und dem Kettengreifersystem 7 sind jeweils
Bogenführungseinrichtungen 10 angeordnet, die für eine
abschmierfreie Bogenführung der bedruckten Bogen sorgen.
Die Bogenführungseinrichtungen 10 haben je nach Verlauf des
Bogentransportwegs gekrümmte oder ebene Leitflächen 11, an
denen die Bogen entlangbewegt werden. Durch das Zuführen
oder Absaugen von Luft über in den Leitflächen 11 angeordnete
Düsen wird eine berührungsfreie Bogenführung erreicht.The printing press shown schematically in FIG. 1 has
several in series arranged
Figur 2 zeigt ausschnittsweise eine Ausführungsform einer
Bogenführungseinrichtung, bei der in einer die Leitfläche
11 bildenden Wand 12 Öffnungen 15 in Form rechteckiger
Schlitze vorgesehen sind, durch die Blasluft in den Zwischenraum
zwischen einem Bogen 16 und der Leitfläche 11
geleitet wird. An den Längsseiten sind die Öffnungen 15
durch Flächen 17 begrenzt, die in einem spitzen Winkel zur
Leitfläche 11 derart geneigt sind, daß die Breite der Öffnungen
15 mit dem Abstand von der Leitfläche 11 zunimmt. In
den Öffnungen 15 sind Lamellen 18 um eine Achse 19 schwenkbar
angeordnet. Die Lamellen 18 haben in symmetrischer
Anordnung zwei konvex gekrümmte Aussenflächen 20, 21, die
an den parallelen Längskanten der Lamellen 18 in einem
spitzen Winkel zusammentreffen. Die Krümmungsachsen der
Außenflächen 20, 21 verlaufen hierbei in Längsrichtung der
Lamellen 18. Durch eine nicht näher dargestellte Stelleinrichtung
können die Lamellen 18 um ihre Achse 19 geschwenkt
und in einer beliebigen Winkelstellung fixiert werden.Figure 2 shows a detail of an embodiment of a
Sheet guiding device, in which the
In Figur 2 sind die Lamellen 18 etwa in einem spitzen
Winkel zur Leitfläche 11 geneigt. Hierdurch wird auf ihrer
Oberseite zwischen den Flächen 17 und den Außenflächen 20
ein als Düse 22 wirkender Spalt gebildet, durch den auf der
Unterseite der Wand 12 zugeführte Blasluft in Form eines
Blasstrahls unter den Bogen 16 geleitet wird. Durch die
gekrümmte Form der Fläche 20 legt sich der Blasstrahl entsprechend
dem Coanda-Effekt an die Lamelle an und tritt
dadurch nahezu parallel zur Leitfläche 11 aus der Düsenöffnung
aus. Auf diese Weise entsteht zwischen dem Bogen 16
und der Leitfläche 11 ein gleichmäßiges Luftpolster, das
den Bogen 16 trägt. Durch Änderung des Anstellwinkels der
Lamellen 18 kann die Richtung des austretenden Blasstrahls
und gleichzeitig der Luftaustrittsquerschnitt und damit
auch die Stärke des Blasstrahls geändert werden. Hierdurch
läßt sich der Blasstrahl optimal an die Bedürfnisse der
Bogenführung bei unterschiedlichen Druckgeschwindigkeiten
und unterschiedlichen Bedruckstoffen anpassen. Der Neigungswinkel
der Lamelle 18 kann auch soweit verkleinert
werden, daß die Lamelle 18 mit der Außenfläche 20 die Fläche
17 berührt, um den Luftaustritt aus der Öffnung 15
weitgehend zu unterbinden. In Figure 2, the
Figur 3 zeigt eine Weiterbildung der Bogenführungseinrichtung
gemäß Figur 2. Die Öffnung 15 in der Wand 12 ist hierbei
so breit ausgeführt, daß nebeneinander fünf Lamellen 18
in der Öffnung 15 angeordnet werden können. Die Außenflächen
20 der Lamellen 18 sind bei diesem Ausführungsbeispiel
weniger stark konvex gekrümmt und die Krümmung der unteren
Außenfläche 21 ist geringer als die der oberen Außenfläche
20. Anstelle einer konvexen Krümmung kann die untere Außenfläche
21 auch mit einer konkaven Krümmung versehen werden.
Die Lamellen 18 sind alle im gleichen Winkel zur Leitfläche
11 geneigt und können wie bei dem Ausführungsbeispiel gemäß
Figur 2 in einem weiten Bereich in ihrer Neigung gemeinsam
und auch unabhängig voneinander verstellt werden. In der
gezeigten Position bilden die Lamellen 18 fünf schlitzförmige
Düsen 22, die unter dem Bogen 16 ein gleichmäßig tragendes
Luftpolster erzeugen.FIG. 3 shows a development of the sheet guiding device
according to Figure 2. The opening 15 in the
