Description

Schleif- und Körnmaschine für Offsetdruckplatten Die Erfindung betrifft eine Schleif- und Körnmaschine für Offsetdruckplatten mit kreisend in der Horizontaalen bewegtem Schleifkasten.Grinding and graining machine for offset printing plates The invention relates to a grinding and graining machine for offset printing plates with circling in the horizontal moving grinding box.

Um die kreisförmige Bewegung der Schleifkästen der Schleif- und Körnmaschinen zu ermöglichen, wurden bisher folgende Wege beschritten. Entweder ruhte der Kasten auf Stahlkugeln, die in Pfannen liefen, oder auf elastischen Stützen, z.B. Manila-Rohrstäben oder Stahlspiralen, oder der Kasten wurde beweglich an Drähten oder Stäben aufgehängt. Außerdem ist die Lagerung der Kästen auf starren Stützen, die auf Stahlkugeln ruhen, bekannt.About the circular movement of the grinding boxes of the grinding and graining machines to enable, the following paths have been taken so far. Either the box was resting on steel balls that ran in pans, or on elastic supports, e.g. Manila pipe rods or steel spirals, or the box was suspended movably on wires or rods. In addition, the boxes are stored on rigid supports resting on steel balls, known.

Der Nachteil dieser bekannten Lagerungen des Schleifkastens besteht in der starken Geräuschentwicklung. Überträgt sich doch das Kugelgeräusch über die Aufhängung auf den Fußboden oder die Decke. Bei der hängenden Lagerung des Schleifkastens kommt außerdem die Behinderung beim Plattenwechsel durch die Drähte oder Stäbe hinzu.The disadvantage of this known bearings of the grinding box is in the strong noise development. The bullet noise is transmitted via the Can be hung on the floor or ceiling. With the hanging storage of the grinding box there is also the hindrance when changing plates due to the wires or rods.

Erfindungsgemäß werden diese Nachteile dadurch beseitigt, daß der Schleifkasten an elastischen, unterhalb desselben an einem Ständer angebrachten Stäben aus Gummi oder gummiähnlichem Material so aufgehängt ist, daß die Stäbe auf Zug beansprucht sind. Durch diese Art der Aufhängung werden Geräuschübertragungen durch die dämpfende Wirkung der auf Zug beanspruchten Gummistäbe vermieden.According to the invention these disadvantages are eliminated in that the Grinding box attached to elastic, underneath the same on a stand Rods made of rubber or rubber-like material is suspended so that the rods on Train are stressed. This type of suspension prevents noise from being transmitted avoided by the damping effect of the rubber rods subjected to tensile stress.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.

Fig. 1 zeigt die Vorderansicht und Fig.2 die Seitenansicht einer Schleif- und Körnmaschine nach der Erfindung.Fig. 1 shows the front view and Fig. 2 the side view of a grinding and a graining machine according to the invention.

Auf einem Ständer 1 ist ein Schleifkasten 2 mittels Gummistäben 3 über an der Unterseite des Schleifkastens 2 angebrachten Streben 4 so aufgehängt, daß die Gummistäbe 3 auf Zug beansprucht sind. Der Antrieb des Schleifkastens 2 erfolgt in an sich bekannter Weise von einem im Ständer 1 untergebrachten Elektromotor 5 aus, der über eine biegsame Welle 6 eine am Kastenboden drehbar gelagerte Schwungscheibe 7 antreibt. Auf der Schwungscheibe 7 ist ein Fliehgewicht 8 angebracht, das den Kasten in kreisende Bewegungen versetzt.On a stand 1 is a grinding box 2 by means of rubber rods 3 suspended via struts 4 attached to the underside of the grinding box 2 in such a way that that the rubber rods 3 are claimed to train. The drive of the grinding box 2 takes place in a manner known per se by an electric motor accommodated in the stand 1 5 from which, via a flexible shaft 6, a flywheel rotatably mounted on the box bottom 7 drives. On the flywheel 7, a flyweight 8 is attached, which the Put the box in circular movements.
