Description

Die Erfindung bezieht sich auf ein Schwebeelement zur Bogenführung in einer Bogen bearbeitenden Maschine, insbesondere in einer Druckmaschine. The invention relates to a floating member to the sheet guide in a sheet-fed machine base, in particular in a printing machine.

Bekannt sind Schwebeelemente, die in Halterungen oder Führungen der Druckmaschine zwischen Druckwerken oder im Bereich eines Bogenauslegers eingesetzt sind, um die Bogenführung besonders an kritischen Stellen zu verbessern. are known floating elements which are inserted in brackets or guides of the printing press between the printing units or in the region of the sheet delivery, to improve the sheet guide particularly at critical locations. Schwebeelemente werden in unterschiedlicher Ausbildung zur schwebenden Bogenstützung auf einem Luftpolster, zur Bogenstraffung, Bogenglättung, zum Bogenbremsen, durch Ansaugung zum schwebend ziehenden Bogentransport eingesetzt. Floating elements are used in different training for floating on an air cushion support sheet, to the sheet lifting, sheet smoothing the sheet brakes, by suction for withdrawing floating sheet transport. Sie bestehen aus einem fest in der Maschine angeordneten Gehäuse mit an der den Bogen führenden Außenseite angeordneten Luftdüsen und einem an das Druckluftsystem und/oder an das Saugluftsystem der Maschine anschließbaren Gehäuseinnenraum. They consist of a fixedly disposed in the machine housing at the sheet-guiding outer side air nozzles are arranged and a connectable to the compressed air system and / or to the suction air system of the machine housing interior. Der notwendige Einsatz solcher Schwebeelemente ist in hohem Maße von der Beschaffenheit des Bedruckstoffes, aber auch von Betriebsbedingungen abhängig. The required use of such floaters depends to a large extent on the nature of the printed material, but also on operating conditions. Schwebeelemente werden daher je nach der Art des abzuwickelnden Auftrages für unterschiedliche Aufgabe an unterschiedlichen Stellen benötigt. Floating elements are therefore required, depending on the type of outstanding order for different tasks at different locations. Häufig sind nicht benötigte Schwebeelemente störend im Wege. Often unnecessary floaters are disruptive in the way. Die Luftversorgung erfolgt durch externe Ansteuerung mit Druckluft oder mit Saugluft. Air is supplied by external actuation with compressed air or suction air.

Aus der DE 42 42 730 A1 sind blasluftversorgte Bogenführungselemente bekannt, die als Wechselkassetten ausgebildet sind. From DE 42 42 730 A1 blasluftversorgte sheet guiding elements are known, which are formed as a removable cassette. Damit ist es möglich, an einer bestimmten Stelle an der Maschine das Bogenführungselement gegen ein anderes mit unterschiedlichen Düsenöffnungen auszutauschen. This makes it possible to exchange at a specific location on the machine, the sheet guide element for another with different nozzle openings. Die Kassetten sind jedoch bedingt durch ihre relativ große Ausdehnung in Bogenlaufrichtung nicht beliebig an anderen Stellen in der Maschine einsetzbar. However, the cartridges are conditioned not be arbitrarily used by their relatively large extent in the direction of sheet travel elsewhere in the machine.

Aus der US-PS 5,088,717 ist eine Blasleiste für den Anleger einer Kopiermaschine bekannt, die stabförmig ist und einen an ihrer Stirnseite angesetzten Ventilator besitzt. From US-PS 5,088,717 a blowing strip to the investor of a copying machine is known, which is rod-shaped and has an attached on its end face fan. Diese Leiste besitzt einen quadratischen Querschnitt und baut deshalb sehr hoch, so daß ihre Einsatzmöglichkeiten zum Beispiel in einer Druckmaschine sehr eingeschränkt sind. This bar has a square cross-section and therefore builds very high, so that their applications are for example very limited in a printing machine.

Es ist Aufgabe der Erfindung, ein Schwebeelement der eingangs genannten Bauart als kompakten Baustein in unterschiedlichen Bereichen wahlweise einsetzbar zu gestalten. It is an object of the invention to create a floating member of the initially mentioned type as a compact module in different areas can be used either.

Diese Aufgabe wird durch eine Ausbildung gemäß den Merkmalen des Patentanspruches 1 gelöst. This object is achieved by a construction according to the features of claim 1.

Ein Schwebeelement mit den Erfindungsmerkmalen kann nachträglich an beliebiger Stelle einer Bogen bearbeitenden Maschine, insbesondere einer Druckmaschine, eingesetzt werden, und zwar zum Bogenstrecken, Bogenbremsen, Bogenbeschleunigen oder Bogenführen, insbesondere beim Umführen, Abrollen oder Halten. A floating member with the invention features may subsequently be processed at any position of a sheet machine, in particular a printing machine, are used, namely to the arc routes sheet brakes, Arch accelerating or sheet guiding, especially during Umführen, rolling or holding.

Bevorzugt wird eine Ausbildung mit einem möglichst flachen Gehäuse in Sandwichbauweise, damit die Unterbringung eines Schwebeelements mit den Erfindungsmerkmalen auch in engen Bauräumen möglich ist. a formation is preferred with a flat housing as possible in a sandwich construction so that the placement of a floating member with the invention characteristics is possible even in confined spaces. Gegebenenfalls können Schwebeelemente aus luftführenden Gehäuseteilen und anderen, die Luftquelle aufnehmenden Gehäuseteilen zusammengesetzt sein. If necessary, suspension elements from air-conducting housing parts and others, the air source may be composed receiving housing parts.

Auf der Zeichnung ist ein Ausführungsbeispiel dargestellt. On the drawing an embodiment is shown. Die Figur zeigt eine Seitenansicht des erfindungsgemäßen Schwebeelementes. The figure shows a side view of the floating element of the invention.

Dieses besteht aus einem stabförmigen Blechgehäuse 1 , welches aus einem im Querschnitt etwa U-förmigen Unterteil 1 a und einem dessen Oberseite dicht abschließenden Oberteil 1 b besteht, wobei dieses Oberteil in Abständen voneinander und in Reihe hintereinander liegende Blasdüsen 2 aufweist. This consists of a rod-shaped sheet metal housing 1, which consists of a cross-sectionally approximately U-shaped lower part 1 a and close a the upper side of the final upper part 1 b, wherein this upper part has at intervals from each other and in series one behind the other tuyeres. 2 Oberteil 1 b und Unterteil 1 a des Blechgehäuses 1 sind an sich überlappenden Rändern luftdicht miteinander verbunden. Upper part 1 b and the lower part 1 a of the sheet metal housing 1 are connected at the overlapping edges air-tight with each other. An einem Stirnende ist das langgestreckte Gehäuse 1 mit einem Ejektor 3 gekuppelt, der mit dem luftführenden Innenraum des Gehäuses 1 verbunden ist. At a front end of the elongated housing 1 is coupled with an ejector 3, which is connected to the air-conducting interior of the housing. 1 Der Ejektor 3 ist über eine Druckluftleitung 4 mit einer entsprechend bemessenen Druckluftquelle oder gegebenenfalls auch mit einem unter entsprechend hoher Vorspannung stehenden Druckluftsystem einer Maschine verbunden. The ejector 3 is connected via a compressed air line 4 with a correspondingly sized source of pressurized air or possibly also with a correspondingly high pretension under compressed air system of a machine.
