Description

Beim Schleifen von Kegelrollen werden bekanntlich dieselben mittels eines langem Rohres, immer mit der Spitze, also dem kleineren Durchmesser voraus der Schleifmaschine, zugeführt. Das Ausrichten der Kegelrollen erfolgte bisher, mangels 'eitler geeigneten Vorrichtung hierzu, besonders beim Fertigschleifen stets mit der Hand. Dieses Verfahren hat den Nachteil, daß. trotz aller Vorsicht immer wieder Rollen verkehrt, also mit dem Kopf voran, in die Maschine gelangen. Die Folge davon können schwere Beschädigungen der Maschine und der Werkzeuge sein. Außerdem können die Rollen nur periodisch eingefüllt und ausgerichtet werden, - es stehen also -einmal viel, 'einmal wenig Rollen im Zuführungsrohr, was sich bei Schneckienschleifrnaschinen ungünstig für den Schneckeneinlauf gestaltet. Bei dem bis oben angefüllten Zubringrohr überschlagen sich hierbei die schon ausgerichteten Kegelrollen in dem zwecks Handeinfüllung offenen Rohrende oftmals.When grinding tapered rollers are known to be the same by means of a long Pipe, always with the point, i.e. the smaller diameter in front of the grinding machine, fed. The alignment of the tapered rollers has so far been done, for lack of 'vain suitable device for this, especially when finishing sanding, always by hand. This Method has the disadvantage that. despite all caution, roles always wrong, so head first into the machine. This can result in severe damage to the machine and tools be. In addition, the rolls can only be filled and aligned periodically, - so there are - once a lot, 'once few rollers in the feed pipe, which is unfavorable for worm grinders designed the screw inlet. Roll over the feed pipe that is filled up to the top Here, the already aligned tapered rollers in the open for manual filling Often the end of the pipe.

Hier soll die Erfindung abhelfen. Zu diesem Zwecke werden die Kegelrollen zunächst in bekannter Weise alle in die Längsrichtung hintereinander gebracht. Nun werden sie quer einer schiefen Ebene zugeführt. Die Zuführung bann entweder durch ein Transportband oder in sonst geeigneter Weise erfolgen. Die Kegelrollen rollen nun durch ihr Eigengewicht auf der schiefen Ebene abwärts, und zwar wiegen ihrer konischen Form im Bogen nach der Seite hin, der ihr kleinerer Durchmesser zugekehrt ist. Dadurch kommen die Kegelrollen alle in einer Richtung zu liegen. Die Kante, an welcher die Rollen die schiefe Ebene verlassen, wird zweckmäßig derart zu einer Kurve ausgebildet, daß sie bei den verschiedenen Kegelwinkeln der rohen 'Rollen stets mit der Rollenachse parallel ist.The invention is intended to remedy this. For this purpose, the tapered rollers first in a known manner, all brought one behind the other in the longitudinal direction. so they are fed across an inclined plane. The feeder disables either by means of a conveyor belt or in any other suitable manner. The tapered rollers now roll down the inclined plane by their own weight, namely weigh their conical shape in the arch towards the side, which faces its smaller diameter is. As a result, the tapered rollers all come to lie in one direction. The edge on which the rollers are crooked Leave level is expediently formed into a curve in such a way that it is at the various Taper angles of the raw 'roles is always parallel to the roll axis.

In. der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt Fig. ι die Seitenansicht der schiefen Ebene, Fig. 2 die Draufsicht auf die schiefe Ebene. Die zu richtenden Kegelrollen werden an der Kante iß der schiefen Ebene & zugeführt. Auf dieser beschreiben die Rollen nach der Seite ihres kleineren Durchmessers hin einen Kreisbogen. Da die zu richtenden Kegelrollen oft sehr verschiedene Konizität besitzen, wird auch der auf der schiefen Ebene beschriebene Kreisbogen verschieden groß sein. Die Rollen werden deshalb an verschiedenen Punkten an die Abfallkante c gelangen. Damit nun Rollenachse und Abfallkante c stets parallel sind, ist letztere kurvenförmig ausgebildet, 'und zwar derart, daß dieselbe mit der Tangente an die Rollenbahn einen rechten Winkel bildet.In. the drawing shows the subject matter of the invention, namely Fig. ι shows the side view of the inclined plane, FIG. 2 shows the plan view of the inclined plane. The tapered rollers to be straightened are fed at the edge of the inclined plane &. On this, the rollers describe an arc of a circle towards the side of their smaller diameter. Since the tapered rollers to be straightened often have very different conicity, the circular arc described on the inclined plane will also be of different sizes. The rolls will therefore come to the waste edge c at different points. So that the roller axis and the trailing edge c are always parallel, the latter is designed to be curved, in such a way that it forms a right angle with the tangent to the roller conveyor.

Die Rollen verlassen die schiefe Ebene b über die Abfallkante c völlig ausgerichtet, also sämtlich mit der Spitze voraus. Das Weiter befördern kann nun durch ein Transportband, 6g Flüssigkeitsstrahl oder in sonst geeigneter Weise erfolgen.The roles leave the inclined plane b over the waste edge c completely aligned, so all with the tip first. The further conveyance can now take place by means of a conveyor belt, 6g liquid jet or in any other suitable manner.
