Abstract
Bei einer Saugfläche zum Fixieren eines Bogens auf einer Bogenauflagefläche sind Saugöffnungen vorgesehen, die in verschiedenen Rastern angeordnet sind, wobei die Raster unterschiedliche Teilungen bzw. Abstände aufweisen, so dass eine Verschiebung der Raster zu kleinen oder größeren Saugflächen führt, insbesondere sind Saugflächen von einem zu verarbeitenden Minimalformat bis zu einem Maximalformat einstellbar.In a suction surface for fixing a sheet on a sheet support surface suction openings are provided, which are arranged in different grids, wherein the grid have different pitches or distances, so that a shift of the grid leads to small or larger suction surfaces, in particular suction surfaces are from one to processing minimum format up to a maximum format adjustable.
Description
Die Erfindung betrifft eine Saugfläche eines Bogentransporttisches oder eines Druckzylinders einer Bogen verarbeitenden Maschine, welche Saugöffnungen zum Fixieren der Bögen aufweist. The invention relates to a suction surface of a sheet transport table or a printing cylinder of a sheet-processing machine, which has suction openings for fixing the sheets.
Durch die
Der Erfindung liegt die Aufgabe zugrunde, eine Saugfläche zu schaffen, welche stufenlos an unterschiedliche Bogenformate anpassbar ist. The invention has for its object to provide a suction surface which is continuously adaptable to different sheet formats.
Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 und 2 gelöst. The object is achieved by the features of
Es ist ein besonderer Vorteil der Erfindung, dass beliebige Formatgrößen fixiert werden können, wobei jedem Bogenformat bis zu seinen Randbereichen aktivierbare Saugöffnungen zugeordnet sind. It is a particular advantage of the invention that any format sizes can be fixed, wherein each sheet format are assigned to its peripheral areas activatable suction openings.
Erfindungsgemäß kann die Saugfläche die Oberfläche eines Tisches oder eines Zylinders sein. According to the invention, the suction surface may be the surface of a table or a cylinder.
Durch diese Maßnahme kann nahezu jeder Bogen vollflächig angesaugt und fixiert werden. By this measure, almost every sheet can be sucked and fixed over the entire surface.
Insbesondere bei einer Verwendung der Saugfläche auf einem Druckzylinder in einer Inkjetdruckeinheit ist es notwendig, dass der Bogen vollflächig angesaugt wird, damit ein notwendiger Abstand zur Inkjetdruckeinheit gleichmäßig eingehalten wird. In particular, when using the suction surface on a printing cylinder in an inkjet printing unit, it is necessary that the sheet is sucked over the entire surface, so that a necessary distance to the inkjet printing unit is maintained evenly.
Zur Erzielung der erfindungsgemäßen Saugfläche sind z. B. mindestens zwei Saugöffnungen aufweisende Bleche oder Folien, bei einem Zylinder gekrümmte Bleche oder Folien, vorgesehen, welche eine unterschiedliche Saugöffnungsverteilung aufweisen und wobei eines der Bleche fest angeordnet ist und das andere oder die beiden anderen gegeneinander verschiebbar angeordnet sind, insbesondere eines in Umfangsrichtung verdrehbar und das zweite in Seitenrichtung verschiebbar angeordnet ist. To achieve the suction surface according to the invention z. B. at least two suction openings having sheets or foils, in a cylinder curved sheets or foils, provided which have a different Saugöffnungsverteilung and wherein one of the sheets is fixed and the other or the other two are arranged mutually displaceable, in particular one rotatable in the circumferential direction and the second is slidably disposed in the lateral direction.
Bei einem zweiten Ausführungsbeispiel weist die Saugfläche ein Saugöffnungen aufweisendes, fest angeordnetes Leitblech und ein gegenüber diesem verschiebbar angeordnetes Schiebeblech auf, welches sowohl in Umfangsrichtung als auch seitlich verschiebbar angeordnet ist. Bei einem Zylinder ist ein Saugöffnungen aufweisendes gekrümmtes Blech vorgesehen, welches in Umfangsrichtung verdrehbar und in Seitenrichtung verschiebbar angeordnet ist. In a second embodiment, the suction surface has a suction openings exhibiting, fixedly arranged baffle plate and a slide plate arranged displaceably with respect to this, which is arranged both in the circumferential direction and laterally displaceable. In the case of a cylinder, a curved plate having suction openings is provided, which is rotatable in the circumferential direction and displaceable in the lateral direction.
Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im Folgenden beschrieben. Embodiments of the invention are illustrated in the drawings and will be described below.
Die mit den Saugöffnungen versehenen Bleche oder Folien sind aus Metall oder Kunststoff hergestellt. The sheets or foils provided with the suction openings are made of metal or plastic.

Außerhalb des Minimalformates sind – in Bogentransportrichtung (Umfangsrichtung) gesehen – Lochreihen mit einem Abstand Z, welcher größer ist als der Abstand Y vorgesehen (Z > Y). Outside the minimum format are - seen in the sheet transport direction (circumferential direction) - rows of holes with a distance Z, which is greater than the distance Y provided (Z> Y).
Außerhalb des Minimalformates in Seitenrichtung gesehen ist der Abstand V zwischen den Lochreihen (V = X + R) und auf der anderen Seite der Abstand W der Lochreihen (W = X – R), wobei R = X – W = V – X ist. Outside the minimum format seen in the lateral direction is the distance V between the rows of holes (V = X + R) and on the other side the distance W of the rows of holes (W = X - R), where R = X - W = V - X.
