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.
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 führt
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.
