Abstract

The aim of the invention is to resharpen a grinding tool, in particular a grinding wheel (1) that is provided for trimming the edges (5) of a glass panel (7). This is achieved in that a resharpening tool (21) is associated with the grinding wheel (1), said resharpening tool being constantly or intermittently active in order to resharpen the grinding wheel (1) during the operation of the grinding wheel (1) to trim edges (5). Halting production for resharpening is thus not necessary, and a constantly unvarying quality of the result of the grinding work (trimmed edge (5) of a glass panel (7)) is ensured.

Description

Verfahren und Anordnung zum Nachschärfen von Schleifscheiben  Method and arrangement for re-sharpening grinding wheels
Die Erfindung betrifft ein Verfahren zum Nachschärfen (Richten) von Schleifscheiben und eine Anordnung, mit der das Verfahren ausgeführt werden kann. The invention relates to a method for re-sharpening (grinding) of grinding wheels and an arrangement with which the method can be carried out.
Insbesondere beim Besäumen der Ränder von Glastafeln werden Schleifscheiben verwendet, die als abrasiven Werkstoff Diamant enthalten. In particular, when trimming the edges of glass panels grinding wheels are used, which contain diamond as an abrasive material.
Problematisch ist es, dass sich das Werkzeug (die Schleifscheibe) abnützt, wenn es zum Schleifen verwendet wird, so dass das Ergebnis des Schleifens, insbesondere die Form der besäumten Ränder von Glastafeln nicht gleichbleibend ist, sondern sich unerwünscht ändert. The problem is that the tool (the grinding wheel) wears off when it is used for grinding, so that the result of the grinding, in particular the shape of the edged edges of glass sheets, is not constant, but changes undesirably.
Bislang wurden Schleifscheiben, nachdem sie einen bestimmten Grad der Abnützung erreicht hatten, aus der Maschine entfernt und in einer gesonderten Maschine nachgeschärft. Dies bedeutet eine Unterbrechung der Produktion für den Schärfvorgang und im Ergebnis eine nicht gleichbleibende Kantenqualität. So far, grinding wheels, after reaching a certain degree of wear, have been removed from the machine and resharpened in a separate machine. This means an interruption of the production for the sharpening process and as a result a non-constant edge quality.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Gattung zur Verfügung zu stellen, welche die geschilderten Nachteile nicht aufweist. The invention has for its object to provide a method and an apparatus of the type mentioned are available, which does not have the disadvantages described.
Gelöst wird diese Aufgabe erfindungsgemäß mit einem Verfahren, welches die Merkmale von Anspruch 1 aufweist. This object is achieved according to the invention with a method having the features of claim 1.
Insoweit die Anordnung betroffen ist, löst die Erfindung die Aufgabe mit einer Anordnung, welche die Merkmale des unabhängigen, auf die Anordnung gerichteten Anspruches aufweist. Bevorzugte und vorteilhafte Ausgestaltungen der Erfindung, sowohl was das Verfahren als auch was die Anordnung betrifft, sind Gegenstand der Unteransprüche. As far as the arrangement is concerned, the invention solves the problem with an arrangement having the features of independent, directed to the arrangement claim. Preferred and advantageous embodiments of the invention, both as regards the method and the arrangement, are the subject matter of the subclaims.
Da bei dem erfindungsgemäßen Verfahren das Schleifwerkzeug (Schleifscheibe) auch während des Benützens der Schleifscheibe zum Schleifen von Werkstücken, insbesondere zum Besäumen der Ränder von Glastafeln, nachgeschärft werden kann, ergeben sich sich keine Produktionsunterbrechungen für den Schärfvorgang (Richtvorgang) der Schleifwerkzeuge (Schleifscheiben) und die Form und die Qualität der nach dem Schleifen erhaltenen Werkstücke, insbesondere der Ränder von Glastafeln, die besäumt worden sind, bleibt gleich. Im Rahmen der Erfindung kann das Nachschärfen in bestimmten, vorgegebenen Zeitabständen oder aber kontinuierlich ausgeführt werden. In the method according to the invention, since the grinding tool (grinding wheel) can also be sharpened during use of the grinding wheel for grinding workpieces, in particular for trimming the edges of glass sheets, there are no production stoppages for the sharpening process (straightening process) of the grinding tools (grinding wheels) and the shape and quality of the workpieces obtained after grinding, in particular the edges of glass sheets which have been trimmed, remain the same. In the context of the invention, the resharpening can be carried out continuously at specific, predetermined time intervals or else.
Insoweit die erfindungsgemäße Anordnung betroffen ist, wird dem Schleifwerkzeug ein Werkzeug zum Schärfen desselben zugeordnet, das an dem Schleifwerkzeug an einer Stelle angreift, die von der Stelle, an der das Schleifwerkzeug am Werkstück angreift, beabstandet ist. As far as the arrangement according to the invention is concerned, the grinding tool is assigned a tool for sharpening the same, which acts on the grinding tool at a location which is spaced from the point at which the grinding tool acts on the workpiece.
Das Werkzeug, das zum Nachschärfen verwendet wird, kann ein stillstehendes oder ein rotierendes Werkzeug sein. The tool used for re-sharpening can be a stationary or a rotating tool.
Eine beispielsweise Anwendung der Erfindung ist es, Schleifscheiben, die Nuten aufweisen, nachzuschärfen, wie sie beispielsweise zum Besäumen von Glastafeln an ihren Rändern verwendet werden. In diesem Fall hat das Werkzeug zum Nachschärfen eine Kontur, die der gewünschten Kontur des besäumten Randes der Glastafel entspricht. For example, an application of the invention is to resharpen grinding wheels having grooves such as are used for trimming glass sheets at their edges. In this case, the re-sharpening tool has a contour corresponding to the desired contour of the edged edge of the glass sheet.
Wenn das Schleifwerkzeug mit Diamant als abrasivem Werkstoff bestückt ist, ist es bevorzugt, wenn das Werkzeug zum Nachschärfen als abrasiven Werkstoff Korund enthält. Es versteht sich, dass, wie beim Schleifen üblich, das Nachschärfen des Schleifwerkzeuges ausgeführt wird, während eine Flüssigkeit zugegeben wird, die kühlt und abgeriebenen Werkstoff entfernt (wegspült). If the grinding tool is equipped with diamond as an abrasive material, it is preferred if the tool contains re-sharpening as an abrasive material corundum. It is understood that, as is common practice in grinding, the sharpening of the abrasive tool is performed while adding a liquid which cools and abrades (scours away) abraded material.
Weitere Einzelheiten und Merkmale der Erfindung ergeben sich der nachstehenden Beschreibung eines bevorzugten Ausführungsbeispieles an Hand der Zeichnungen. Further details and features of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings.
Es zeigt It shows
Fig. 1 schematisch eine Anordnung zum Ausführen des erfindungsgemäßen Verfahrens in Seitenansicht und  Fig. 1 shows schematically an arrangement for carrying out the method according to the invention in side view and
Fig. 2 eine Schrägansicht zu Fig. 1. 2 is an oblique view to Fig. 1st
In dem gezeigten Ausführungsbeispiel ist das Schleifwerkzeug eine Schleifscheibe 1 , die eine ringförmige Nut 3 aufweist, mit welcher der Rand 5 einer Glastafel 7 besäumt wird, so dass der Rand 5 dann einen abgerundeten, z.B. annähernd halbkreisförmigen, Querschnitt aufweist. Die Schleifscheibe 1 wird durch einen nicht gezeigten Antrieb in Drehung versetzt, wobei die Richtung der Drehung (Pfeil 9) der Relativbewegung zwischen Glastafel 7 und Schleifwerkzeug 1 entgegengerichtet ist, wie dies in Fig. 1 durch die Pfeile 9 und 11 angedeutet ist. In Fig. 1 ist auch angedeutet, dass der Schleifscheibe 1 mit Abstand von dem Angriffspunkt 13 der Schleifscheibe 1 an dem Rand 5 der Glastafel 7 ein Werkzeug 21 (die in der Zeichnung dargestellte unregelmäßige Umrissform des Werkzeuges 21 ist nur eine zeichentechnische Maßnahme, das Werkzeug 21 ist "abgerissen" dargestellt) zum Nachschärfen zugeordnet ist. Dieses Werkzeug 21 zum Nachschärfen ist z.B. als stillstehendes Werkzeug ausgebildet, das in Richtung des Pfeiles 23 in die Nut 3 der Schleifscheibe 1 gedrückt wird. Wenn die Schleifscheibe 1 mit Diamant als abrasiven Werkstoff bestückt ist, kann das Nachscharfwerkzeug 21 aus Korund bestehen oder mit Korund als abrasiven Werkstoff bestückt sein. Die Umrissform des Werkzeuges 21 kann kreisförmig oder polygonal, z.B. achteckig, sein. In the embodiment shown, the grinding tool is a grinding wheel 1, which has an annular groove 3, with which the edge 5 of a glass sheet 7 is trimmed, so that the edge 5 then has a rounded, for example approximately semicircular, cross-section. The grinding wheel 1 is rotated by a drive, not shown, wherein the direction of rotation (arrow 9) of the relative movement between the glass sheet 7 and grinding tool 1 is directed opposite, as indicated in Fig. 1 by the arrows 9 and 11. In Fig. 1 is also indicated that the grinding wheel 1 at a distance from the point 13 of the grinding wheel 1 on the edge 5 of the glass sheet 7, a tool 21 (the irregular outline shape of the tool 21 shown in the drawing is only a drawing technical measure, the tool 21 is "demolished" shown) is assigned for resharpening. This tool 21 for re-sharpening is formed, for example, as a stationary tool which is pressed in the direction of the arrow 23 in the groove 3 of the grinding wheel 1. If the grinding wheel 1 is equipped with diamond as an abrasive material, the sharpening tool 21 may consist of corundum or be equipped with corundum as an abrasive material. The outline shape of the tool 21 may be circular or polygonal, eg octagonal.
Vorteilhaft bei der erfindungsgemäßen Anordnung ist es, wenn das Werkzeug 21 zum Nachschärfen wenigstens einen Abschnitt aufweist, der mit dem selben Radius gekrümmt ist wie die wirksame Fläche der Schleifscheibe 1 (im Beispiel die Nut 3) und eine Kontur aufweist, die der Kontur entspricht, die der Rand 5 der Glastafel 7 nach dem Besäumen haben soll. It is advantageous in the arrangement according to the invention if the resharpening tool 21 has at least one section which is curved with the same radius as the effective surface of the grinding wheel 1 (in the example the groove 3) and has a contour corresponding to the contour, which should have the edge 5 of the glass sheet 7 after trimming.
Vorteilhaft bei der in Fig. 1 und 2 gezeigten Anordnung ist, dass das Werkzeug 21 zum Nachschärfen der Schleifscheibe 1 in dem Bereich der Schleifscheibe 1 , der sich vom Werkstück 7 wegbewegt, angeordnet ist, und nicht in dem Bereich, der sich zum Werkstück 7 hinbewegt. It is advantageous in the arrangement shown in FIGS. 1 and 2 that the tool 21 for re-sharpening the grinding wheel 1 is arranged in the region of the grinding wheel 1 which moves away from the workpiece 7, and not in the region which faces the workpiece 7 moving towards.
Dies bedeutet, dass das Werkzeug 21 der Hälfte 2 der Schleifscheibe 1 zugeordnet ist, die sich von der Eingriffsstelle 13 der Schleifscheibe (1 ) am Werkstück (Glastafel 7) wegbewegt. Dies hat den Vorteil, dass die für das Besäumen der Glastafel 7 aufgebrachte Kühl- und Spülflüssigkeit auch in hinreichendem Ausmaß für das Nachschärfen zur Verfügung steht, so dass in vielen Anwendungsfällen ein gesondertes Aufgeben von Kühl- und Spülflüssigkeit für das Nachschärfen nicht erforderlich ist. Der Angriff des Werkzeuges 21 an der Schleifscheibe 1 kann ständig sein oder das Werkzeug 21 wird in vorgegebenen und einstellbaren Zeitabständen in Eingriff mit der Schleifscheibe 1 gebracht, um diese nachzuschärfen. This means that the tool 21 of the half 2 is associated with the grinding wheel 1, which moves away from the engagement point 13 of the grinding wheel (1) on the workpiece (glass panel 7). This has the advantage that the cooling and rinsing liquid applied for trimming the glass panel 7 is also available to a sufficient extent for re-sharpening, so that in many applications a separate application of cooling and rinsing liquid for re-sharpening is not required. The attack of the tool 21 on the grinding wheel 1 can be permanent or the tool 21 is brought in predetermined and adjustable intervals in engagement with the grinding wheel 1, to sharpen this.
Zusammenfassend kann ein Ausführungsbeispiel der Erfindung wie folgt beschrieben werden: In summary, an embodiment of the invention can be described as follows:
Um ein Schleifwerkzeug, insbesondere eine Schleifscheibe 1 , die zum Besäumen der Ränder 5 einer Glastafel 7 vorgesehen ist, nachzuschärfen, ist der Schleifscheibe 1 ein Nachschärfwerkzeug 21 zugeordnet, das während des Betriebes der Schleifscheibe 1 , um Ränder 5 zu besäumen, ständig oder intermittierend tätig ist, um die Schleifscheibe 1 , nachzuschärfen. So sind Produktionsstillstände für das Nachschärfen nicht erforderlich und es wird eine ständig gleichbleibende Qualität des Ergebnisses der Schleifarbeit (besäumter Rand 5 einer Glastafel 7) gewährleistet. In order to re-sharpen a grinding tool, in particular a grinding wheel 1, which is provided for trimming the edges 5 of a glass sheet 7, the grinding wheel 1 is associated with a re-sharpening tool 21 which operates continuously or intermittently during operation of the grinding wheel 1 in order to edge edges 5 is to the grinding wheel 1, resharpen. So production stoppages for resharpening are not required and it is a constantly consistent quality of the result of the grinding work (edged edge 5 of a glass sheet 7) guaranteed.
