Description

Vorrichtung 'zur Speisung von stetig arbeitenden Holzschleifern Es sind Vorrichtungen zur Speisung von stetig arbeitenden Holzschleifern zum Schleifen von Holz, holzartigen Trümmern, Faserstengeln u. dgl. bekannt, bei denen ein Walzenpaar mit darin beweglichen Fördermitteln das Arbeitsgut der Schleifwalze zutreibt. Bei diesen Einrichtungen bewegt sich das Arbeitsgut selbst durch einen Schacht, und die Walzen greifen mit ihren Fördermitteln seitlich in diesen Schacht ein. Der sich dadurch ergebende Aufbau ist nichteinfach genug und macht Schwierigkeiten hinsichtlich des unteren Schachtabschlusses.Device for feeding continuously working wood grinders Es are devices for feeding continuously working wood grinders for sanding of wood, wood-like debris, fiber stalks and the like. Known in which a pair of rollers drives the work material to the grinding roller with movable conveyors. at these facilities move the work material itself through a shaft, and the rollers engage with their conveying means laterally in this shaft. Which the resulting structure is not simple enough and poses difficulties as to of the lower shaft end.

Erfindungsgemäß werden diese Schwierigkeiten dadurch behoben, daß die in@,den Walzen vorgesehenen Mitnehmer zum Ergreifen und Freigebendes Gutes gegenüber der Walzenachse radial hin und her bewegbar angeordnet sind. Dadurch kann man die Förderwalze in unmittelbare Berührung mit dem Schleifstein bringen und braucht dann einen besonderen Schachtkörper nicht vorzusehen. Die Walzen selbst begrenzen seitlich den Schachtraum. Eine besondere Abdichtung 'ist nicht vorgesehen. Es treten die radial beweglichen Mitnehmer vollständig in die Förderwalzen hinein, sobald sie in die Verbindungsebene zwischen den Achsender einzelnen Förderwalzen und der Schleifwalze geraten, um dann wieder aus ihrem Spalt nach außen hervorzutreten. Bei dieser radialen Hinundherbewegbarkeit der Mitnehmer in den Förderwalzen kann man nun mehrere solcher Walzenpaare derart hintereinander anordnen, daß man -dadurch einen verhältnismäßig tiefen Zuführungsschacht erhält, den allein die Förderwalzen bilden.According to the invention, these difficulties are eliminated in that the drivers provided in @, the rollers for gripping and releasing goods opposite the roller axis are arranged such that they can be moved radially back and forth. This allows you to use the Bring the conveyor roller into direct contact with the grindstone and then needs not to provide a special shaft body. The rollers themselves limit laterally the shaft room. A special seal is not provided. The radially movable driver completely into the conveyor rollers as soon as they in the connection level between the axes of the individual conveyor rollers and the grinding roller advised to then emerge again from their gap to the outside. With this radial The reciprocation of the driver in the conveyor rollers can now be several such Arrange pairs of rollers one behind the other in such a way that one is relatively receives deep feed shaft, which alone form the conveyor rollers.

In -der Zeichnung sind schematisch zwei Ausführungsbeispiele von Speisevorrichtungen nach der Erfindung dargestellt. Bei beiden sind z die Schleifsteine, 2, 211 bzw. 3, 3d die die Mitnehmer tragenden Walzenpaare. In den Walzenkörpern 2, 211 bzw. 3, 3d sind Mitnehmer 5 radial hin und her bewegbar angeordnet. Bei der Drehung ihrer Walzen im Sinne der eingezeichneten Pfeile um die Achse 6 laufen die Mitnehmer mit ihren inneren Kanten an feststehenden Exzentern 4 entlang und erhalten -dabei die aus der Zeichnung ersichtlichen Stellungen, bei denen die punktiert eingezeichneten Mittelstellungen auftreten. Die Mitnehmer können auf der ganzen Länge der Walzen durchlaufende Schienen oder auch Stiftringe oder sonstige gleichwertige Mittel sein. Die bei den Baumwollvorbereitungsmaschinen benutzten Zylinder mit radial durch Exzenter hin und her gehenden bzw. aus ihnen hinaustretenden und wieder in sie hineingehenden und darin verschwindenden Stiften dienen einem ganz anderen Zwecke, als er bei der Vorrichtung zur Speisung stetig arbeitender Holzschleifer auftritt.In the drawing are two exemplary embodiments of feed devices shown according to the invention. For both, z are the grindstones, 2, 211 and 3, 3d the pairs of rollers carrying the drivers. In the roller bodies 2, 211 and 3, 3d drivers 5 are arranged such that they can be moved radially back and forth. When turning her Rollers in the sense of the arrows drawn around the axis 6 run with the drivers their inner edges on fixed eccentrics 4 along and received -this positions shown in the drawing, in which the dotted lines Mid-positions occur. The drivers can run along the entire length of the rollers continuous rails or pin rings or other equivalent means. The cylinders used in the cotton preparation machines have a radial eccentric going back and forth or stepping out of them and going back into them and the pens disappearing in it serve a completely different purpose than he did with the Apparatus for feeding continuously working wood grinders occurs.
