Abstract

Die Erfindung befaßt sich mit einer Vorrichtung und einem Verfahren zum Reinigen eines mit kubischem Bornitrid beschichteten Schleifkörpers (14) innerhalb einer Vorrichtung zum Trennen von Tabak von einem Tabakkuchen. Beim Trennen von Tabak werden die Trennelemente während der Tabakverarbeitung durch geeignete beschichtete Schleifkörper (14) nachgeschliffen. Aufgrund der Ablagerung von Tabaksoße und Tabakstaub an der Schneidkante des Trennelementes, die sich auch auf dem Schleifkörper (14) niederschlägt, ist eine Reinigung des Schleifkörpers (14) erforderlich.The invention relates to a device and a method for cleaning a cubic boron nitride coated abrasive article (14) within a device for separating tobacco from a tobacco cake. When separating tobacco, the Separating elements during tobacco processing by means of suitable coated grinding wheels (14) reground. Due to the deposition of tobacco sauce and tobacco dust the cutting edge of the separating element, which also deposits on the grinding wheel (14), a cleaning of the grinding wheel (14) is required.

Bei bekannten Vorrichtungen und Verfahren werden die Schleifkörper mit gehärteter Oberfläche durch das sogenannte "Abziehen" mittels eines Diamanten gereinigt und somit von der Tabaksoße und den Staubresten befreit. Dies hat jedoch den Nachteil, daß durch Abnutzung des Schleifkörpers selbst zum einen die Standzeit des Schleifkörpers gering ist und zum anderen ein kontinuierlicher Vorschub desselben erforderlich ist, was zu einem komplexen Aufbau der Vorrichtung führtIn known devices and methods, the grinding wheels are hardened Surface cleaned by the so-called "peeling" by means of a diamond and thus freed from the tobacco sauce and the dust residues. However, this has the disadvantage that by abrasion of the abrasive body itself on the one hand the life of the abrasive body is low and on the other a continuous feed of the same is required resulting in a complex structure of the device

Die Aufgabe, eine Vorrichtung und ein Verfahren zum Reinigen eines Schleifkörpers (14) vorzuschlagen, bei der der Schleifkörper (14) zum Schärfen der Trennelemente während des Betriebes effektiv und einfach zu reinigen ist, wird erfindungsgemäß dadurch gelöst, daß Mittel (16) vorgesehen sind, mittels denen das Reinigen des Schleifkörpers durch Aufbringen eines Strahls aus flüssigem oder gasförmigem Medium auf den Schleifkörper erfolgt. Dadurch wird eine den Schleifkörper (14) schonende und effektive Reinigung ermöglicht.

Figure 00000001
The object of providing a device and a method for cleaning an abrasive article (14) in which the abrasive article (14) is effective and easy to clean during operation for sharpening the separator elements is achieved in accordance with the invention by providing means (16) by means of which the cleaning of the abrasive article by applying a jet of liquid or gaseous medium is carried out on the abrasive body. As a result, an abrasive cleaning (14) gentle and effective cleaning is possible.
