Abstract

In the air cushion roller (1), air streams fed through a hollow space (12) in the interior of the roller emerge from openings in the roller jacket (8), by means of which air streams the sheets are pressed away from the roller jacket (8). For reducing the air stream noise, a noise-absorbing layer (18) is provided in the hollow space (12) with radial channels (19), which forms in the hollow space (12) an air-permeable partition wall equidistant from the roller jacket (8).

Description

Die Erfindung betrifft eine Luftkissentrommel für Bogen­druckmaschinen, bei der aus Öffnungen im Trommelmantel durch einen Hohlraum im Innern der Trommel zugeführte Luftströme austreten, durch die die Bogen vom Trommel­mantel weggedrückt werden.The invention relates to an air cushion drum for sheet-fed printing presses, in which air flows are supplied from openings in the drum shell through a cavity in the interior of the drum and through which the sheets are pressed away from the drum shell.

Eine Luftkissentrommel der angegebenen Art ist aus der DE-PS 1 561 043 bekannt. Der Trommelmantel besteht bei dieser bekannten Luftkissentrommel aus einem porösen Ma­terial, so daß die Luft über die Trommellänge gleich­mäßig verteilt aus einer Vielzahl von Poren radial ins Freie tritt und auf dem Trommelumfang ein dünnes Luft­polster bildet, wodurch eine Berührung der bedruckten Bogen mit der Trommel und damit ein Verschmieren des Druckfarbenauftrags verhindert wird. Die bekannte Trom­mel ist doppelwandig ausgeführt und der durch die Dop­pelwandung geschaffene Hohlraum ist durch Rippen in ein­zelne, sich parallel zur Trommelachse erstreckende Kam­mern aufgeteilt, die mit Hilfe von Steuerungselementen während einer Umdrehung der Trommel nacheinander mit Luft versorgt werden.An air cushion drum of the type specified is known from DE-PS 1 561 043. In this known air cushion drum, the drum jacket consists of a porous material, so that the air is radially distributed evenly over the drum length from a large number of pores and forms a thin air cushion on the drum circumference, causing the printed sheets to come into contact with the drum and thus smearing of the ink application is prevented. The known drum is double-walled and the cavity created by the double wall is divided by ribs into individual chambers extending parallel to the drum axis, which are supplied with air in succession by means of control elements during one revolution of the drum.

In der Praxis haben sich Luftkissentrommeln der angegebenen Art bewährt. Die durch die Luftströme verursachten Ge­räusche werden jedoch als nachteilig empfunden.Air cushion drums of the specified type have proven themselves in practice. However, the noises caused by the air currents are perceived as disadvantageous.

Aufgabe der Erfindung ist es, eine Luftkissentrommel der ein­gangs genannten Art zu schaffen, bei der die Strömungsge­räusche gering sind.The object of the invention is to provide an air cushion drum of the type mentioned, in which the flow noise is low.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß den Öffnungen für den Luftaustritt im Trommelmantel im Hohl­raum eine schallabsorbierende Schicht gegenüberliegt.This object is achieved in that the openings for the air outlet in the drum shell in the cavity is opposite a sound absorbing layer.

Überraschenderweise hat sich gezeigt, daß durch die erfin­dungsgemäße Anbringung einer schallabsorbierenden Schicht im Hohlraum der Trommel, durch den die Luft zugeführt wird, eine erhebliche Reduzierung der Strömungsgeräusche erreicht wird.Surprisingly, it has been shown that the application of a sound-absorbing layer according to the invention in the cavity of the drum through which the air is supplied results in a considerable reduction in the flow noise.

Eine noch wirksamere Geräuschreduzierung läßt sich nach einem weiteren Vorschlag der Erfindung dadurch erreichen, daß die schallabsorbierende Schicht in dem Hohlraum eine zum Trommelmantel im wesentlichen äquidistante, luft­durchlässige Trennwand bildet, durch die die Luft zur In­nenseite des Trommelmantels hindurchgeleitet wird. Diese Anordnung hat zusätzlich den Vorteil, daß eine gleich­mäßige Druckverteilung über die gesamte Trommelbreite er­reicht wird und sich ein gleichmäßiges Luftkissen unter dem Bogen einstellt. Die schallabsorbierende Schicht der Trennwand kann erfindungsgemäß von einem Gitter getragen werden und es kann zur Minderung des Strömungswiderstands vorgesehen sein, daß die Streben des Gitters einen in Strömungsrichtung tropfenförmigen Querschnitt haben. Um auch den Strömungswiderstand der schallabsorbierenden Schicht möglichst klein zu halten, kann diese nach einem weiteren Vorschlag der Erfindung mit einer Vielzahl radi­aler Kanäle versehen sein. Dabei hat sich gezeigt, daß durch diese Kanäle die schallabsorbierende Wirkung noch begün­stigt wird.An even more effective noise reduction can be achieved according to a further proposal of the invention in that the sound-absorbing layer in the cavity forms an air-permeable partition wall which is essentially equidistant from the drum shell and through which the air is passed to the inside of the drum shell. This arrangement has the additional advantage that a uniform pressure distribution over the entire drum width is achieved and a uniform air cushion is created under the arch. According to the invention, the sound-absorbing layer of the dividing wall can be carried by a grating and, in order to reduce the flow resistance, it can be provided that the struts of the grating have a cross-section which is drop-shaped in the direction of flow. In order to keep the flow resistance of the sound-absorbing layer as low as possible, it can be provided with a plurality of radial channels according to a further proposal of the invention. It has been shown that the sound-absorbing effect is further favored by these channels.

Die schallabsorbierende Schicht kann erfindungsgemäß mit einer formstabilen Schicht, vorzugsweise aus Kunststoff, ummantelt sein, die die durch die Luftströmung und die Drehbewegung der Trommel hervorgerufenen Kräfte aufnimmt und die Schicht an dem Gitter festhält. Erfindungsgemäß ist die schallabsorbierende Schicht aus Filz hergestellt.According to the invention, the sound-absorbing layer can be coated with a dimensionally stable layer, preferably made of plastic, which absorbs the forces caused by the air flow and the rotary movement of the drum and holds the layer to the grille. According to the invention, the sound absorbing layer is made of felt.

Als besonders wirkungsvoll haben sich die erfindungsge­mäßen Maßnahmen in Verbindung mit einem Trommelmantel er­wiesen, der aus mehreren luftdurchlässigen Schichten zu­sammengesetzt ist. Vorzugsweise besteht dabei der Trom­melmantel in der Reihenfolge von innen nach außen aus ei­nem Stützsieb, einem Filterkarton und einem Decksieb.The measures according to the invention in connection with a drum jacket, which is composed of several air-permeable layers, have proven to be particularly effective. The drum jacket preferably consists of a support screen, a filter carton and a cover screen in the order from the inside to the outside.

Die Erfindung wird nachfolgend anhand eines in der Zeich­nung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung zeigt einen Querschnitt durch eine erfin­dungegemäße Luftkissentrommel.The invention is explained in more detail below with reference to an embodiment shown in the drawing. The drawing shows a cross section through an air cushion drum according to the invention.

Die dargestellte Luftkissentrommel 1 besteht aus einem in­neren im wesentlichen zylindrischen Trommelkörper 2, der mit geteilten Flanschringen 3, 4 auf einer durchgehenden Welle befestigbar ist. An beiden Enden weist der Trommel­körper 2 sich keglig nach außen erweiternde Stirnwände 5, 6 auf, an die sich jeweils ein radialer Ringbund 7 an­schließt. Auf den beiden Ringbünden 7 ist ein Trommelman­tel 8 befestigt, der aus drei aufeinanderliegenden, luft­durchlässigen Schichten besteht, nämlich aus einem innen­liegenden Stützsieb 9, einem mittleren Filterkarton 10 und einem äußeren Decksieb 11.The air cushion drum 1 shown consists of an inner, essentially cylindrical drum body 2, which can be fastened on a continuous shaft with divided flange rings 3, 4. At both ends, the drum body 2 has conically widening end walls 5, 6, to each of which a radial annular collar 7 is connected. A drum jacket 8, which consists of three air-permeable layers lying one on top of the other, is attached to the two ring bundles 7, namely an inner support sieve 9, a middle filter box 10 and an outer cover sieve 11.

In dem Hohlraum 12 zwischen dem Trommelmantel 8 und dem Trommelkörper 2 ist konzentrisch zu diesen ein Gitter 13 vorgesehen, welches aus achsparallelen Streben 14 und in Umfangsrichtung verlaufenden Streben 15 gebildet ist.In the cavity 12 between the drum casing 8 and the drum body 2, a grating 13 is provided concentrically to the latter, which is formed from struts 14 which are parallel to the axis and struts 15 extending in the circumferential direction.

Durch radiale und achsparallele Wände 16, die sich von dem Trommelkörper 2 bis zum Trommelmantel 8 erstrecken, ist der Hohlraum 12 in einzelne Kammern unterteilt, die während einer Umdrehung der Trommel 1 über Zuführkanäle 17 nacheinander an eine Luftzufuhr angeschlossen werden können.By means of radial and axially parallel walls 16, which extend from the drum body 2 to the drum casing 8, the cavity 12 is divided into individual chambers which can be connected in succession to an air supply via feed channels 17 during one revolution of the drum 1.

Auf dem Gitter 13 ist eine Schicht 18 aus einem schallab­sorbierenden Material, beispielsweise einem Schaumstoff oder einem Fasermaterial befestigt, die eine Vielzahl ra­dialer Kanäle 19 für den Durchtritt der Luft hat. Auf ihrer Außenseite ist die Schicht 18 mit einer formstabilen Schicht 20 überzogen, durch die die Schicht 18 auf dem Gitter 13 gehalten wird und die die radial nach außen ge­richteten Strömungs- und Fliehkräfte aufnimmt. Die Schicht 20 ist ebenfalls von den Kanälen 19 durchsetzt. Die Au­ßenfläche der Schicht 20 befindet sich in einem Abstand von dem Trommelmantel 8, so daß die Luft zur gesamten In­nenfläche des Trommelmantels 8 freien Zutritt hat. Außer­dem wird durch diesen Abstand die schalldämmende Wirkung der Schicht 18 erhöht.A layer 18 made of a sound-absorbing material, for example a foam or a fiber material, is fastened on the grille 13 and has a plurality of radial channels 19 for the passage of air. On its outside, the layer 18 is coated with a dimensionally stable layer 20, by means of which the layer 18 is held on the grating 13 and which absorbs the flow and centrifugal forces directed radially outwards. The layer 20 is also penetrated by the channels 19. The outer surface of the layer 20 is at a distance from the drum shell 8, so that the air has free access to the entire inner surface of the drum shell 8. In addition, the sound-absorbing effect of the layer 18 is increased by this distance.

Die schallabsorbierende Schicht kann aus Faserstoffen oder einem Schaumstoff bestehen. Bevorzugt wird ein Filz verwen­det, da dieser eine hohe Dämmwirkung hat, sich gut verar­beiten läßt und die Mitnahme von Fasern durch die Luft minimal ist.The sound absorbing layer can consist of fibrous materials or a foam. A felt is preferably used because it has a high insulating effect, is easy to process and the entrainment of fibers in the air is minimal.

Durch die Anordnung der schallabsorbierenden Schicht 18 werden bei der beschriebenen Trommel die auftretenden Strö­mungsgeräusche in starkem Maße gedämpft, wobei die schall­absorbierende Schicht auf ihrer Innen- und Außenseite eine Dämpfungswirkung entfaltet. Die schallabsorbierende Schicht 18 trägt wieterhin zu einer gleichmäßigen Druckverteilung auf der Innenseite des Trommelmantels 8 bei, indem sie die mit vergleichsweise hoher Strömungsgeschwindigkeit seit­lich durch die Zuführkanäle 17 einströmende Luft abbremst und über die Kanäle 19 mit ausgeglichenem Druck in Rich­tung auf den Trommelmantel 8 umlenkt.The arrangement of the sound-absorbing layer 18 in the drum described dampens the flow noises to a great extent, the sound-absorbing layer developing a damping effect on its inside and outside. The sound-absorbing layer 18 further contributes to an even pressure distribution on the inside of the drum shell 8 by the Decelerates air flowing in laterally through the supply channels 17 at a comparatively high flow rate and deflects them via the channels 19 with a balanced pressure in the direction of the drum jacket 8.
