The compressed-air pipe is positioned in the middle inside a slot-shaped nozzle (2) connected to a vacuum fan (10). Part-slots are positioned on both sides of the compressed air pipe. The slot-shaped nozzle including the width of the compressed air pipe has a total width of 15 to 25 millimetres. the air outlets are spaced apart by 7 -15, preferably 8 -10, millimetres.

Description

Die Erfindung betrifft eine Druckmaschine, die zum Reinigen der zugeführten, insbesondere bogen- oder bahnförmigen Druckträger mit einer Reinigungseinrichtung versehen ist, die eine sich senkrecht zur Druckträger-Förderrichtung erstreckende, mit auf die Druckträger-Förderbahn gerichteten Luftauslässen versehene Druckluftleitung aufweist, die im wesentlichen mittig innerhalb einer an eine Saugluftquelle angeschlossenen Schlitzdüse angebracht ist, derart, daß beidseitig von der Druckluftleitung Teilschlitze gebildet sind. The invention relates to a printing press for cleaning the supplied, in particular sheet or sheet-shaped printing medium is provided with a cleaning device, the one extending perpendicular to the printing medium conveying direction, with air outlets directed towards the print carrier conveyor track Compressed air line which is substantially centered within a slot nozzle connected to a suction air source is attached such that on both sides of the compressed air line Partial slots are formed.

Bei den von den Papieroberflächen zu entfernenden Partikeln handelt es sich unter anderem in erster Linie um Trennmittel, die ein Anhaften zwischen benachbarten Papierlagen verhindern sollen.For the particles to be removed from the paper surfaces are primarily release agents, which prevent sticking between adjacent layers of paper should.

Der in der DE-20 06 716 beschriebenen Reinigungsvorrichtung zum Absaugen von Staub von einer Druckmaschine zuzuführenden bahnförmigen Druckträgern lag der grundsätzlich richtige Gedanke zugrunde, durch eine kombiniertes Druckluft-Saugluftsystem den Reinigungseffekt zu optimieren. Ausgehend davon, daß die zeichnerische Darstellung der DE-20 06 716 A im Großen und Ganzen repräsentativ für die Abmessungen der bekannten Reinigungsvorrichtung sind, hat der die beiden einzelnen Saugschlitze und die Druckluftleitung (Blaskasten) aufnehmende Saugkasten eine Gesamtbreite, die etwa dem 14- bis 19-fachen der Öffnungsbreite der Druckluftauslässe entspricht, während die Druckluftleitung (Blaskasten) eine Gesamtbreite hat, die etwa dem 10- bis 14-fachen der Breite der Druckluftauslässe entspricht. Der zu reinigende Druckträger wird demzufolge aufgrund der großen Breite des Saugkastens einer erhöhten elektrostatischen Aufladung ausgesetzt, wodurch die Gefahr entsteht, daß infolge der von den Druckluftauslässen relativ weit entfernten Saugspalten bereits mittels der Druckluft von dem Druckträger losgelöste und aufgewirbelte Staubpartikel sich wieder an der Druckträgerbahn ablagern können. Dieser Tendenz kann auch nur in geringem Umfang dadurch entgegengewirkt werden, daß mehrere Reihen von Druckluftauslässen vorhanden sein können.The cleaning device described in DE-20 06 716 for extracting dust to be fed from a printing press web-like print media was basically the right idea based on a combined compressed air-suction air system Optimize cleaning effect. Assuming that the graphic Representation of DE-20 06 716 A largely representative for the dimensions of the known cleaning device the two individual suction slots and the Suction box receiving compressed air line (blow box) a total width, which is about 14 to 19 times the opening width of the Compressed air outlets correspond while the compressed air line (Blow box) has a total width that is about the 10- to 14 times the width of the compressed air outlets. The too cleaning print media is therefore due to the large width the suction box is exposed to increased electrostatic charge, which creates the risk that as a result of the compressed air outlets already relatively far away by means of suction gaps the compressed air detached and whirled up by the pressure carrier Dust particles can be deposited on the print carrier web again. This tendency can only be counteracted to a small extent there will be several rows of compressed air outlets could be.

Der Erfindung liegt die Aufgabe zugrunde, die der bekannten Vorrichtung anhaftenden, oben beschriebenen Nachteile zu beheben. Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Luftauslässe einen Durchmesser von 2 - 4 mm, vorzugsweise 2,5 - 3 mm, haben, und daß die Schlitzdüse einschließlich der von der Druckluftleitung eingenommenen Breite eine Gesamtbreite im Bereich von 15 - 25 mm hat. The invention is based, that of the known task To fix device-inherent disadvantages described above. To achieve this object, the invention provides that the air outlets have a diameter of 2 - 4 mm, preferably 2.5 - 3 mm, and that the slot nozzle including those taken up by the compressed air line Width has a total width in the range of 15-25 mm.

Das die Erfindung tragende Merkmale besteht somit im wesentlichen darin, die Saugschlitze in unmittelbarer Nähe der Druckluftauslässe anzuordnen um sicherzustellen, daß bereits von dem Druckträger abgelöste Staubpartikel sich nicht wieder auf dem Druckträger ablagern können, indem die Gesamtbreite der Schlitzdüse einschließlich der Druckluftleitung nur etwa dem 6-fach Durchmesser der Druckluftauslässe entspricht.The features bearing the invention thus essentially exist in it, the suction slots in the immediate vicinity of the Arrange compressed air outlets to ensure that already Dust particles detached from the print carrier do not reappear can deposit on the print carrier by the total width the slot nozzle including the compressed air line only about corresponds to 6 times the diameter of the compressed air outlets.

Der im Anspruch 4 behandelten Lösung liegt die Teilaufgabe zugrunde, die Umweltbelastung so gering wie möglich zu halten.The solution dealt with in claim 4 is the subtask to keep the environmental impact as low as possible.

Weitere Merkmale der Erfindung sind in den Unteransprüchen behandelt.Further features of the invention are in the subclaims treated.
