Abstract
Bogenleiteinrichtung für Bogen im Bereich einer Wendeeinrichtung in einer Bogen verarbeitenden Maschine, wobei die Bogenleiteinrichtung pneumatisch beaufschlagbar ist, dadurch gekennzeichnet, dass die Bogenleiteinrichtung (34) jenseits einer gemeinsamen Tangente (T) angeordnet ist, die sich von einer der Wendeeinrichtung (28, 31) vorgeordneten Übergabetrommel (33) bis zur Wendetrommel (31) erstreckt, dass die Bogenleiteinrichtung (34) im Bereich unterhalb der Speichertrommel (28) mindestens eine Saugeinrichtung (36) aufweist, dass die Saugeinrichtung (36) eine Anordnung von in Reihe nebeneinander vorgesehenen Sauglüftern umfasst und dass die Bogenleiteinrichtung (34) im Bereich unterhalb der Wendetrommel (31) und des nachgeordneten Zylinders (29) mindestens eine Blaseinrichtung (37) aufweist, dass die Blaseinrichtung (37) mindestens eine quer zur Bogentransportrichtung angeordnete Reihe von Blaslüftern aufweist, und dass die Sauglüfter und die Blaslüfter in Abhängigkeit von der Grammatur der zu verarbeitenden Bogen und der Verarbeitungsgeschwindigkeit geregelt werden.Sheet guiding device for sheets in the region of a turning device in a sheet-processing machine, wherein the sheet guiding device can be acted upon pneumatically, characterized in that the sheet guiding device (34) is arranged beyond a common tangent (T) extending from one of the turning devices (28, 31) upstream transfer drum (33) to the turning drum (31) that the sheet guiding device (34) in the area below the storage drum (28) at least one suction device (36), that the suction device (36) comprises an array of suction fans in series next to each other and in that the sheet guiding device (34) has at least one blowing device (37) in the region below the turning drum (31) and the downstream cylinder (29), that the blowing device (37) has at least one row of blower fans arranged transversely to the sheet transporting direction, and that the Suction fan and the blower fan depending on the Grammage of the processed sheets and the processing speed are regulated.
Description
Bogenleiteinrichtung für Bogen einer Bogen verarbeitenden Maschine, insbesondere im Bereich einer Wendeeinrichtung, bei der der Bogen von einem vorgeordneten Druckzylinder übernommen mittels einer Wendetrommel gewendet und einem nachfolgenden Druckzylinder übergeben wird.Sheet guiding device for sheets of a sheet-processing machine, in particular in the area of a turning device, in which the sheet taken from an upstream printing cylinder turned by means of a turning drum and transferred to a subsequent impression cylinder.
Insbesondere bei einer Ein-Trommel-Wendeeinrichtung neigen leichte Grammaturen bei höheren Druckgeschwindigkeiten im Wendebetrieb zu sehr unruhigem Bogenlauf im Speicherbereich und damit unterhalb der Wendetrommel, was zu unerwünschter Faltenbildung und Knicken im Bogen bzw. der Grammatur führen kann und damit die Qualität beeinträchtigt.In particular, in a single-drum turning device light grammages tend at higher printing speeds in turning mode to very restless sheet travel in the storage area and thus below the turning drum, which can lead to unwanted wrinkles and wrinkles in the sheet or the grammage and thus affects the quality.

Es liegt der Erfindung die Aufgabe zugrunde, eine Bogenleiteinrichtung im Bereich der Wendetrommel – insbesondere bei einer Ein-Trommel-Wendeeinrichtung – zu schaffen, welche nicht mit dem gewendeten Bogen in Berührung gelangt.It is the object of the invention to provide a sheet guiding device in the area of the turning drum, in particular in the case of a single-drum turning device, which does not come into contact with the turned arc.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.
Es ist ein besonderer Vorteil der Erfindung, dass die erfindungsgemäße Bogenleiteinrichtung in großem Abstand zu den bogenführenden Trommeln und Zylindern angeordnet ist. Durch diese Maßnahme wird gewährleistet, dass die zu wendenden Grammaturen oder Bogen nicht in Kontakt mit der Bogenleiteinrichtung gelangen. Hierbei ist es von besonderem Vorteil, dass die Bogenleiteinrichtung im hinteren Bereich des Bogens, insbesondere in der Phase während des Lösens und Abziehens des Bogens vom vorherigen Zylinder, eine pneumatische Beaufschlagung mit Unterdruck erzeugt und im vorderen Bereich eine pneumatische Beaufschlagung mit Überdruck (z. B. Blasluft) erzeugt. Durch diese Maßnahmen wird sichergestellt, dass der hintere Bogenbereich schnell nach unten vom Druckzylinder bzw. der Speichertrommel abgezogen wird, während die Blaseinrichtungen dafür sorgen, dass keine Berührung zwischen Bogen und Bogenleiteinrichtung stattfindet. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.It is a particular advantage of the invention that the sheet guiding device according to the invention is arranged at a great distance from the sheet-guiding drums and cylinders. This measure ensures that the grammages or sheets to be used do not come into contact with the sheet guiding device. It is particularly advantageous that the sheet guiding device in the rear region of the sheet, in particular in the phase during the loosening and removal of the sheet from the previous cylinder, generates a pneumatic application of negative pressure and in the front region a pneumatic admission with overpressure (z Blown air). These measures ensure that the rear sheet area is quickly pulled down from the printing cylinder or the storage drum, while the blowing devices ensure that no contact between sheet and sheet guide takes place. Further advantageous embodiments are described in the subclaims.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden beschrieben.An embodiment of the invention is illustrated in the drawings and will be described below.
