Description

Bei Messerschleifvorrichtungen mit zwei sich kreuzenden Schleifwalzen wird das Messer leicht in einer falschen Richtung zwischen den Mantelflächen der Schleifkörper hindurchgezogen, so daß. es sich unter dem Druck der führenden Hand festklemmt. Diesem Übelstand suchte man durch einen Führungsschlitz für den Messerrücken in dem die Schleifwalzen umgebenden Gehäuse abzuhelfen. Abgesehen von der dadurch erhöhten Hemmung der Schleifbewegung des Messers entsteht der Nachteil, daß- sich die Messerklinge mit ihren Keilflächen an den Schlitzkanten reibt und dadurch geschrammt oder sonstwie beschädigt wird.In knife sharpening devices with two intersecting grinding rollers, the knife easily pulled in the wrong direction between the outer surfaces of the grinding wheels, so that. it gets stuck under the pressure of the leading hand. This evil one looked through a guide slot for the knife back in which the grinding rollers the surrounding housing. Apart from the resulting increased inhibition of the grinding movement of the knife the disadvantage that the knife blade rubs against the edges of the slot with its wedge surfaces and thereby scratched or otherwise damaged.

Es sind ferner Schärfvorrichtungen mit mehreren Schleifwalzenpaaren bekannt. Hierbei wird zwar, insbesondere wegen der zwangsläufigen Führung des Messers ein Klemmen der Schneide verhütet; doch wirken sämtliche Walzenpaare- als Schärf rollen für je einen bestimmten Teil der Klinge, wobei noch der Umstand zu beachten ist, daß. infolge der Unmöglichkeit des gleichzeitigen und gleichmäßigen Anliegens sämtlicher Walzen an der Schneide ein unregelmäßiges und zu Scharten führendes Abziehen der Klinge eintritt.There are also known sharpening devices with several pairs of grinding rollers. Here is a jamming, especially because of the inevitable guidance of the knife the edge avoids; but all roller pairs act as sharpening rollers for one each certain part of the blade, noting the fact that. as a result of Impossibility of the simultaneous and even contact of all rollers to the Cut an irregular and nicking peeling of the blade occurs.

Durch die Erfindung wird die Aufgabe gelöst, das Messer unter weitgehender Schonung sicher und gerade zu führen. Hierzu dient ein die Messerschneide mit rollender Reibung senkrecht führender Wälzkörper. Zweckmäßig wird die Führungswalze derart zu den Schärfrollen gelagert, daß sie die Schneidenbahn des Messers tangiert.The invention solves the problem, the knife with extensive protection safe and straight to lead. A knife edge with rolling friction is used for this purpose vertically leading rolling elements. The guide roller expediently becomes the sharpening rollers in this way stored that it touches the cutting path of the knife.

Durch diese neue Ausbildung des Gerätes wird das Messer bzw. die zu schärfende Klinge in einer dem Schärfgang günstigsten Lage gehalten, und dieses kann, ohne sich zu klemmen, zwischen den Schärf rollen hindurchgezogen werden. Die Führungswalze übt hierbei keine Schleif wirkung auf die Messerschneide aus, sondern wirkt infolge der tangentialen Lage zur Schneidenbahn glättend auf diese.With this new design of the device, the knife or the one to be sharpened The blade is held in the most favorable position for the sharpening gear, and this can be done without having to clamp, be pulled through between the sharpening rollers. The guide roller exercises this no grinding effect on the knife edge, but acts as a result of the tangential Position to the cutting path smoothing on this.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel nachIn the drawing, the subject matter of the invention is shown in an exemplary embodiment according to

Fig. ι in einer Seitenansicht mit weggeschnittener Seitenwand undFig. Ι in a side view with cut away Sidewall and

Fig. 2 in Draufsicht hierzu dargestellt.Fig. 2 is shown in plan view of this.

Die Schleifwalzen 1, 2 der Schleifvorrichtung sind mit sich kreuzenden Drehachsen 5 in Gelenkaugen 6 eines kastenförmigen Rahmens 3 gelagert. Das Führungsglied für die Schneide besteht in einer Walze 4, die im Rahmen 3 so gelagert ist, daß sie die Schneide mit der dieser zugekehrten Seitenfläche tangential berührt und ohne Schärfwirkung beim Hinundhergang auf ihr gleitet bzw. abrollt. Die Führungswalze 4 übt somit eine Glattwirkung auf die von den Schleifwalzen 1, 2 abgezogene Klinge aus. Auf diese Weise wird die Messerklinge an einer Verdrehung oder Windschieflage, in die sie sonst infolge der gekreuzten Stellung der Schleifwalzen gelangen könnte, und somit am Festklemmen verhindert und stets in der richtigen Schleifrichtung geführt.The grinding rollers 1, 2 of the grinding device have axes of rotation 5 that cross one another mounted in hinge eyes 6 of a box-shaped frame 3. The leading link for the The cutting edge consists of a roller 4 which is mounted in the frame 3 so that it is the cutting edge touched tangentially with the side face facing this and without a sharpening effect at Moving back and forth on it slides or rolls off. The guide roller 4 thus exerts a smooth effect onto the blade pulled off the grinding rollers 1, 2. In this way If the knife blade is twisted or tilted, it would otherwise result the crossed position of the sanding rollers could get, and thus get stuck prevented and always guided in the correct grinding direction.
