Description
DEUTSCHESGERMAN
Für das Polieren von Glasplatten werden Werkzeuge benutzt, die eine Relativbewegung gegenüber den zu polierenden Platten erhalten und auf diese einen gewissen Druck ausüben, wobei Flüssigkeit zugeführt wird, die von Natur aus oder durch ein von ihr in Suspension mitgeführtes Poliermittel mit den Werkzeugen polierend wirkt.For polishing glass plates, tools are used that move relative to one another receive the plates to be polished and exert a certain pressure on them, whereby liquid is supplied by nature or by a polishing agent carried along in suspension with the tools has a polishing effect.
Die Erfindung bezieht sich insbesondere auf Werkzeuge zum Polieren eines Glasbandes, das ununterbrochen unter in der Bewegungsrichtung hintereinander angeordneten Polierwerkzeugen fortbewegt wird. Hierbei werden z. B. Polierwerkzeuge von rechteckiger Form benutzt, deren Länge ungefähr der Breite des Glasbandes entspricht und die quer zum Glasband angeordnet sind. Durch Kanäle, die die Werkzeuge durchsetzen und auf ihrer Arbeitsfläche münden, wird den Werkzeugen die Polierflüssigkeit unter Druck zugeführt. Da bei dieser Anordnung das Werkzeug eine verhältnismäßig große Fläche des Glasbandes bedeckt, ist es schwierig, die Polierflüssigkeit auf alle mit dem Glas in Berührung kommende Stellen des Werkzeuges gleichmäßig zu verteilen.The invention particularly relates to tools for polishing a ribbon of glass that is continuous is advanced under polishing tools arranged one behind the other in the direction of movement. Here z. B. Polishing tools of rectangular shape used, the length of which is approximately the width of the Glass ribbon corresponds and which are arranged transversely to the glass ribbon. Through channels that enforce the tools and open onto their work surface, the tools are supplied with the polishing fluid under pressure. Since with this arrangement the tool covers a relatively large area of the glass ribbon, it is difficult to apply the polishing fluid to all parts of the tool that come into contact with the glass to distribute evenly.
Die Erfindung hat den Zweck, diese Schwierigkeit zu beheben. Sie besteht dar^n, daß die mit dem Glas in Berührung kommende Arbeitsfläche des Polierwerkzeuges mit quer zur Werkstückbewegungsrichtung verlaufenden Rinnen versehen ist, in welche die die Polierflüssigkeit zuführenden Kanäle münden, wobei von zwei benachbarten Rinnen wenigstens eine mit einer oder mit mehreren Zufuhröffnungen für die Flüssigkeit versehen ist.The invention aims to overcome this problem. She insists that the one with the glass Working surface of the polishing tool that comes into contact with that which extends transversely to the direction of movement of the workpiece Grooves is provided, in which the polishing liquid feed channels open, from two adjacent channels at least one with one or more feed openings for the liquid is provided.
Vorzugsweise sind alle reibenden Teile des Werkzeuges durch die Rinnen derart begrenzt, daß für alle Punkte der zu polierenden Fläche bei gleicher Bearbeitungsdauer eine annähernd gleiche Summe der wirksamen Einzelstrecken am Werkzeug gewährleistet ist.Preferably, all rubbing parts of the tool are limited by the grooves so that for all Points of the surface to be polished with the same processing time an approximately equal sum of the effective Individual stretches on the tool is guaranteed.
Gemäß der Erfindung können geschlossene Rinnen für Flüssigkeitszufuhr mit offenen Rinnen mit Flüssigkeitsabfluß abwechseln.According to the invention, closed channels for liquid supply with open channels with liquid drainage alternate.
Es können aber auch alle Rinnen Flüssigkeitszu- und -abflußöffnungen aufweisen, die so bemessen sind, daß in den Rinnen ein Flüssigkeitsdruck entsteht, der die an der Polierstelle wirkende Flüssigkeitsmenge bestimmt.However, all channels can also have liquid inflow and outflow openings that are dimensioned in such a way that that a liquid pressure arises in the grooves, the amount of liquid acting at the polishing point certainly.
Bei der letzteren Ausführung sind die Rinnen zweckmäßig an ihrem einen Ende geschlossen, an ihrem anderen Ende offen und die Zuflußöffnungen nahe dem geschlossenen Ende jeder Rinne vorgesehen.In the latter embodiment, the channels are expediently closed at one end and at the other End open and the inflow openings provided near the closed end of each channel.

Das in Abb. 1 dargestellte Polierwerkzeug hat die Form eines Rechtecks, dessen zur Schmalseite parallele Achse mit X-X bezeichnet ist. Es hat Reibstreifen, die sich über die ganze Länge des Rechtecks erstrecken und mit Bezug auf die Achse X-X symmetrisch sind. Es sind vier Reibstreifen 1, 2, 3, 4 dargestellt, die von einer mittleren geschlossenen Rinne 5, die durch Öffnungen 6 gespeist wird, und durch zwei offene Abflußrinnen 7, 8 begrenzt sind.The polishing tool shown in Fig. 1 has the shape of a rectangle, the one parallel to the narrow side Axis is labeled X-X. It has rub strips that run the length of the rectangle and are symmetrical with respect to the X-X axis. There are four rub strips 1, 2, 3, 4 shown, that of a central closed channel 5, which is fed through openings 6, and by two open gutters 7, 8 are limited.
