Description
Die Erfindung bezieht sich auf eine Anordnung, insbesondere eine Einrichtung zum Schleifen von Platten aus Glas oder ähnlichen Stoffen.The invention relates to an arrangement, in particular a device for grinding plates made of glass or similar materials.
Die Erfindung richtet sich auf umlaufende Werkzeuge mit zentraler Schleif mittel Versorgung, insbesondere zum Klarschleifen eines sich kontinuierlich vorwärts bewegenden Glasbandes.The invention is directed to rotating tools with a central grinding medium supply, in particular for clear grinding of a continuously moving glass ribbon.
Bekanntlich hat der Schleifkopf solcher Werkzeuge die Form einer Krone" and enthält durch Kanäle getrennte Schleifrippen, wobei die Kanäle von einem mittleren Durchlaß ausgehen und zum Rand hin verlaufen, ohne aus der Seitenfläche des Werkzeuges auszutreten. Die Schleifmittelsuspension wird durch die Mittelöffnung zugeführt und verteilt sich in den Verteilungskanälen unter dem Einfluß des Verteilungsdruckes und der-auf sie wirkenden Zentrifugalkraft.As is known, the grinding head of such tools has the shape of a crown and contains channels separated by channels Grinding ribs, with the channels starting from a central passage and running towards the edge, without coming out of the side surface of the tool. The abrasive suspension is through the Central opening supplied and distributed in the distribution channels under the influence of the distribution pressure and the centrifugal force acting on them.
Sie tritt an den Enden der Kanäle aus und überschwemmt beim Umlauf des Werkzeuges das Glasband. ■■ ■It emerges at the ends of the channels and floods the glass ribbon as the tool rotates. ■■ ■
Es zeigt sich dabei, daß die Schleifmittelsuspension nur pulsierend und ungenügend austritt, so daß sich eine ausreichende Zirkulation nicht aufrechterhalten läßt, d. h. nicht immer ausreichend frisches Schleifmittel auf der Glasoberfläche zur Verfugung steht.It turns out that the abrasive suspension emerges only pulsating and insufficiently, so that fails to maintain adequate circulation, d. H. not always enough fresh abrasive is available on the glass surface.
Durch den nur intermittierenden Austritt der Schleifmittelflüssigkeit ist ein Absetzen der größeren Sandkörner möglich, so daß, bedingt durch eine etwaige Ansammlung von Sandkörnern oder ein Trockenlauf en der Schleifflächen, gefährliche Überhitzungserscheinungen auftreten, die zur Unbrauchbarkeit des behandelten Glases führen.Due to the only intermittent discharge of the abrasive liquid, the larger ones settle out Grains of sand possible, so that, due to a possible accumulation of grains of sand or dry running of the grinding surfaces, dangerous overheating phenomena occur which render the treated surface unusable Lead glass.
Weiterhin ist bei dieser Vorrichtung ein gleichmäßiger Zufluß der S;chleifflüssigkeit nicht gewährleistet. Hierdurch entstehen leicht unterschiedliche Strukturen auf der Glasoberfläche, die die Unbrauchbarkeit des Glases bedingen.Furthermore, with this device, a uniform flow of the grinding liquid is not guaranteed. This creates slightly different structures on the glass surface that make it unusable of the glass.
Es ist auch bereits bekannt, den Druck der Schleifmittelflüssigkeit durch Anwendung einer in Art von kommunizierenden Röhren ausgebildeten Zuführungsleitung konstant zu halten. Bei dieser bekannten Vorrichtung wird jedoch das Problem der kontinuierlichen Führung der Schleifmittelflüssigkeit über die zu schleifende Fläche nicht gelöst, so daß auch hier Ablagerungen und damit Fehler beim Schleifen auftreten können.It is also already known to reduce the pressure of the abrasive fluid by using an in kind of To keep communicating tubes trained supply line constant. In this known device however, the problem of continuously guiding the abrasive liquid over the too Abrasive surface not solved, so that deposits and thus errors occur when sanding can.
Durch die Erfindung werden diese Nachteile beseitigt, indem man am äußersten Ende der Verteilungskanäle Öffnungen vorsieht, die den Abfluß des Schleifmittels sichern und seinen Druck innerhalb des Kanals konstant halten. Hierdurch ist eine gleichmäßige Beschickung der Glas- und Schleifflächen mit Schleifflüssigkeit gewährleistet und der Anfall an Ausschußware in derartigen Betrieben erheblich herabgesetzt. The invention overcomes these disadvantages by providing openings at the extreme end of the distribution channels which allow the abrasive to drain secure and keep its pressure constant within the canal. This is a uniform Filling of the glass and grinding surfaces with grinding liquid guaranteed and the accumulation on Rejects in such establishments are considerably reduced.

Durch die Erfindung ist ferner sichergestellt, daß das Schleifmittel aus den Kanälen während des ganzen Umlaufs des Werkzeuges und nicht nur beim Austritt des Kanalendes über den Glasbandrand austreten kann, so daß im Kanal immer der gewünschte Flüssigkeitsdruck aufrechterhalten wird.The invention also ensures that the abrasive from the channels during the whole Around the tool and not only when the end of the duct exits over the edge of the glass ribbon, so that the desired fluid pressure is always maintained in the channel.
Die erfindungsgemäßen Austrittsöffnungen weisen vorzugsweise einen regelbaren Querschnitt auf, um in jedem Falle die optimale Schleifmittelverteilung zu erzielen.The outlet openings according to the invention preferably have a controllable cross section in order to to achieve the optimal distribution of abrasives in each case.
Die Austrittsöffnung kann ein am Grund des Kanalendes vorgesehenes Loch sein. Vorzugsweise wird die Austrittsöffnung mit Vorrichtungen versehen, die den Austrittsquerschnitt zu verändern gestatten, z. B. mit einem Kegelventil oder Nadelventil, einem Gummiklappenventil od. dgl.The outlet opening can be a hole provided at the bottom of the channel end. Preferably the The outlet opening is provided with devices that allow the outlet cross-section to be changed, e.g. B. with a cone valve or needle valve, a rubber flap valve or the like.
Gemäß einer anderen Ausführungsform der Erfindung wird der Austritt des Kanalendes ins Freie dadurch erhalten, daß man den Rand der Schleifoberfläche des Glasbearbeitungswerkzeuges über einen Abrichtschleifstein od. dgl. laufen läßt. Hierbei wird der Außenrand des Glasbearbeitungswerkzeuges so weit abgenommen, bis die Radialkanäle den gewünschten Austrittsquerschnitt haben.According to another embodiment of the invention, the exit of the channel end into the open is thereby obtained that the edge of the grinding surface of the glass processing tool over a dressing grindstone or the like. Here, the outer edge of the glass processing tool becomes so wide removed until the radial channels have the desired outlet cross-section.
