US-Patente 40 58 201 und 38 96 536 legen auch sogenannte Quer­ richter vor, in welchen die Späne in der Querrichtung auf den Späne­ förderer gesetzt werden.A chip judge of this type is e.g. B. featured in U.S. Patent 4,388,055 sets. US Patents 40 58 201 and 38 96 536 also lay so-called cross judge in which the chips crosswise on the chips promoters are set.

Die Aufgabe der vorliegenden Erfindung ist, einen neuen Typ von Spänerichter zu schaffen, der einfach, billig, und zuverlässig ist.The object of the present invention is to create a new type of chip judge that is simple, cheap, and is reliable.

Der erfindungsgemäße Spänerichter ist dadurch gekennzeichnet, daß die Richtelemente aus radialen Schaufelstrukturen bestehen, die längs­ weise auf ihren Achsen befestigt sind. Bei Anwendung des erfindungsge­ mäßen Spänerichters werden alle durch den Spänerichter durchgehende Späne in derselben Richtung auf den darunter gelegenen Späneförderer gesetzt. Die Späne setzen sich in die gleiche Richtung schon beim Fallen in die Zwischenräume zwischen den Schaufeln, und sie werden noch genauer gerichtet, wenn sie zwischen den Schaufeln von oben nach unten und weiter auf den Späneförderer bewegen. Die Späne strömen auch sehr gleichmäßig durch die Spalte zwischen den Richtelementen, so daß die sich auf dem Späneförderer bildende Späneschicht auch sehr gleichmäßig ist.The chip judge according to the invention is characterized in that the straightening elements consist of radial blade structures that run lengthways are wisely attached to their axes. When using the fiction According to the chip judge, all who pass through the chip judge Chips in the same direction on the chip conveyor below set. The chips set in the same direction when Fall into the gaps between the blades and they will even more precisely when directed between the blades from the top move down and further onto the chip conveyor. The chips are flowing too very evenly through the gap between the straightening elements, see above that the chip layer forming on the chip conveyor is also very is even.

Eine vorteilhafte Ausführungsform der Erfindung ist dadurch gekenn­ zeichnet, daß die Richtvorrichtung mit zwischen den Richtelementen gelegenen Hüllblechen versehen ist, die die Richtelemente teilweise umhüllen. Die länglichen Späne setzen sich in die zwischen den Schaufeln und den Hüllblechen gebildeten keilförmigen Zwischenräume und gleiten vorwärts auf der Innenseite des Hüllblechs, bevor sie auf den Späneförderer fallen, wobei alle Späne in der gleichen Richtung gerichtet sind.An advantageous embodiment of the invention is characterized records that the straightening device with between the straightening elements located cladding is provided, which partially the straightening elements envelop. The elongated chips settle in between the Blades and the cladding formed wedge-shaped spaces  and slide forward on the inside of the cladding sheet before going on the chip conveyor fall, with all chips in the same direction are directed.

Eine andere vorteilhafte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß die Schaufeln derart keilförmig ausgeformt sind, daß ihre Durchschnittsbreite von der Schaufelspitze her gegen die Achse wächst. Zwischen den Schaufeln und den Hüllblechen sind damit keilförmige Räume gebildet, die den Richtvorgang fördern.This is another advantageous embodiment of the invention characterized in that the blades are shaped in a wedge shape, that their average width from the tip of the blade against the Axis is growing. So there are between the blades and the cladding wedge-shaped spaces that promote the straightening process.

Die Erfindung wird nachfolgend anhand eines Beispieles unter Bezugnahme auf die Zeichnungen näher erläutert.The invention will be described below with reference to an example explained in more detail on the drawings.

Fig. 1 zeigt die Hauptteile des Spänerichters schräg von oben gesehen. Fig. 1 shows the main parts of the chip judge seen obliquely from above.

Fig. 2 zeigt das Richtelement gemäß einer Ausführungsform vom Ende gesehen. Fig. 2 shows the directional element according to one embodiment viewed from the end.

Spänerichter zum Richten von Spänen auf einer Späneförderlinie, welcher Spänerichter aus Ausbreitungswalzen 1 besteht, die den Späne­ strom auf eine unter den Ausbreitungswalzen gelegene Richtvorrichtung 2 ausbreitet, in welcher die Späne gerichtet und dann in der erwünschten Richtung auf den darunter gelegenen Späneförderer 3 gesetzt werden. Die Richtvorrichtung besteht aus mehreren nebeneinan­ der gelegenen, um ihre Achsen 4 rotierenden Richtelementen. Die Richt­ elemente bestehen aus radialen Schaufelstrukturen 5, die längsweise auf ihren Achsen 4 befestigt sind. Die Richtvorrichtung ist mit zwischen den Richtelementen gelegenen, die Richtelemente teilweise umhüllenden Hüllblechen 6 versehen. Die Schaufeln 5 sind derart keil­ förmig ausgeformt, daß die Breite ihres Durchschnitts von der Schau­ felspitze her gegen die Achse 2 wächst. Die länglichen Späne setzen sich in die keilförmigen Zwischenräume 7, wobei sie schon teilweise in der erwünschten Richtung gerichtet werden. Spätestens bei der Phase 8 gleiten die Späne auf der steilen Schaufelseite 9 in den Keilraum zwischen der Schaufelseite 9 und der Hüllfläche 10 nieder, wobei sie genauer gerichtet werden. Bei der Phase 11 bleiben die Späne momentan auf dem Hüllblech stehen, und die Schaufelkante 12 schiebt sie weiter vorwärts, bis sie auf den unter der Richtvorrichtung laufenden Späne­ förderer 3 niederfallen. Da die Späne um die Hüllblechkante 13 in kleinen Partien niederfallen und dabei an einander gestützt sind, geschieht beim freien Fallen fast keine Zerstörung der Richtung der Späne.Chip straightener for straightening chips on a chip conveyor line, which chip straightener consists of spreading rollers 1 , which spreads the chips stream onto a straightening device 2 located under the spreading rollers, in which the chips are straightened and then placed in the desired direction on the underlying chip conveyor 3 . The straightening device consists of several juxtaposed straightening elements rotating about their axes 4 . The straightening elements consist of radial blade structures 5 , which are fastened longitudinally on their axes 4 . The straightening device is provided with cladding plates 6 located between the straightening elements and partially enveloping the straightening elements. The blades 5 are wedge-shaped in such a way that the width of their average from the show felspitze grows against the axis 2 . The elongated chips settle into the wedge-shaped spaces 7 , whereby they are already partially directed in the desired direction. At the latest in phase 8, the chips slide down on the steep blade side 9 into the wedge space between the blade side 9 and the envelope surface 10 , whereby they are more precisely aligned. In phase 11 , the chips currently remain on the cladding sheet, and the blade edge 12 pushes them further forward until they fall onto the chip conveyor 3 running under the straightening device. Since the chips fall around the cladding sheet edge 13 in small portions and are supported on one another, there is almost no destruction of the direction of the chips when falling freely.

Es ist dem Fachmann offenbar, daß die Erfindung nicht auf die oben beschriebenen Ausführungsbeispiele beschränkt ist, sondern daß sie im Rahmen der folgenden Patentansprüche variiert werden kann. So kann z. B. der Späneförderer in der Horizontalebene winkelig, sogar in einem Winkel von 90 Grad, zur Richtvorrichtung angebracht sein, wobei die Späne sich schräg oder sogar längsweise auf den Späneförderer setzen.It will be apparent to those skilled in the art that the invention is not limited to the above described embodiments is limited, but that they in The scope of the following claims can be varied. So can e.g. B. the chip conveyor is angled in the horizontal plane, even in one Angle of 90 degrees to the straightening device, the Chips are placed on the chip conveyor at an angle or even lengthways.
