Auf einem Rahmen 8 ist die Guttransporteinrichtung angeordnet. Sie besteht aus einer Gutaufgabestation 6, an die sich eine Aufschlagzone 2 anschließt. Auf diese folgt eine Zone für eine Kontrollsiebung 5, um ungeeignete Teilchen abzuführen. Danach ist eine Konditionierungszone 3 vorgesehen, in der das Schüttgut befeuchtet wird. Flüssiges Wasser wird an einer Abtropfstrecke 4 abgeführt. In einer an die Abtropfstrecke 4 folgenden Zellenradschleuse 7 werden die Schüttgutteilchen vereinzelt, wobei mittels einer Sensorik die notwendige Vereinzelung der Objekte in der Detektionsebene erfolgt. Beim Verlassen der Zellenradschleuse 7 erfolgt die Trennung der Schüttgutteilchen mittels einer Gutselektierstation 9. Die selektierten Schüttgutteilchen gelangen dann durch Schwerkraft auf Bodenförderer 10, 11 und werden abgeführt. The material transport device is arranged on a frame 8. it consists of a delivery station 6, which is followed by a service zone 2. On this follows a zone for a control sieve 5 for unsuitable particles dissipate. Thereafter, a conditioning zone 3 is provided, in which the Bulk material is moistened. Liquid water is drained 4 dissipated. In a cellular wheel sluice 7 following the draining section 4 the bulk material particles isolated, the necessary using a sensor system The objects are separated in the detection plane. When leaving the Cell wheel lock 7 is used to separate the bulk material particles by means of a Good selection station 9. The selected bulk goods particles then pass through Gravity on floor conveyor 10, 11 and are discharged.

Am ausgangsseitigen Endabschnitt 12 der Abtropfstrecke 4, der als Abwurfkante ausgebildet ist, ist eine nach unten geneigte Rutsche 13 angeordnet, auf die das entfeuchtete Schüttgut gelangt (Fig. 2). Im Abstand a von dem Endabschnitt 12 ist im Abstand b von der Oberfläche der Rutsche 13 die Zellenradschleuse 7 angeordnet. Diese kann als Bürstenwalze ausgebildet sein. Sie ist über der Rutsche 13 so angeordnet, daß die Teilchen des Schüttgutes durch die Bürstenwalze eingezogen und nach dem Angleichen der Geschwindigkeit wieder freigegeben werden. Über einen nicht näher dargestellten Frequenzumrichter kann die Umfangsgeschwindigkeit der Bürstenwalze verändert werden. In einer Ebene unter dem unteren Endabschnitt 28 der Rutsche 13 ist eine Zeilenkamera 14 und ein dieser zugeordneter Hintergrund 15 angeordnet. Es können auch zwei Zeilenkameras 14 oder eine durch eine lichtempfindliche Diodenkette gebildete Zeile vorgesehen werden.At the outlet-side end section 12 of the draining section 4, which acts as a discharge edge is formed, a downwardly inclined slide 13 is arranged on which dehumidified bulk material arrives (Fig. 2). At a distance a from the end section 12 is the rotary valve 7 at a distance b from the surface of the slide 13 arranged. This can be designed as a brush roller. It is over the Slide 13 arranged so that the particles of the bulk material through the Brush roller retracted and after adjusting the speed again be released. Via a frequency converter, not shown the peripheral speed of the brush roller can be changed. In a Level below the lower end portion 28 of the slide 13 is a line scan camera 14 and a background 15 assigned to it. It can also be two Line cameras 14 or one formed by a light-sensitive diode chain Line can be provided.

Wie in Fig. 3 dargestellt, ist vor der Zeilenkamera 14 ein Kamerafilter 16 angeordnet, der für Normallicht, Ultraviolettlicht und Infrarotlicht wirksam ist. Der durch die Zeilenkamera 14 und den Hintergrund 15 gebildeten Meßstrecke ist eine Beleuchtungseinrichtung 17 zugeordnet. Die Beleuchtungseinrichtung 17 besteht aus 3 Dioden oder Leuchten 18, 19, 20, die jeweils Ultraviolettlicht bzw. Infrarotlicht bzw. Normallicht ausstrahlen. Diese drei Lichtfraktionen werden je nach zu sortierendem Produkt gemischt. Vor den Dioden oder Leuchten 18, 19, 20 ist ein Langpaßfilter 21 angeordnet.As shown in FIG. 3, there is a camera filter 16 in front of the line camera 14 arranged, which is effective for normal light, ultraviolet light and infrared light. Of the measuring line formed by the line camera 14 and the background 15 an illumination device 17 is assigned. The lighting device 17 consists of 3 diodes or lights 18, 19, 20, each of which is ultraviolet light or Emit infrared light or normal light. These three light fractions are each mixed by product to be sorted. In front of the diodes or lights 18, 19, 20 a long pass filter 21 is arranged.

Unter der Beleuchtungseinrichtung 17 sind in der Detektionsebene einander entgegengesetzt zwei Düsenstöcke 22, 23 angeordnet, die mit Druckluft von z.B. 3 - 6 bar Druck beaufschlagt werden. Die Druckluft kann gekühlt auf z.B. 1 - 3°K unter Umgebungstemperatur oder aber auch ungekühlt sein. Die Düsen sind wandungseng aneinandergereiht. Die Düsendurchmesser können 0,8 bis 6 mm betragen. Die Düsenstöcke 22, 23 werden gegenläufig angesteuert, damit mit einem Sortiervorgang drei Produktqualitäten unterschiedlicher Graustufe anfallen. Das Produkt B gelangt im freien Fall in einen Aufnahmebehälter 24. Das Produkt A wird durch den Düsenstock 23 aus dem Schüttgutstrom 27 ausgelenkt und fällt in den Aufnahmebehälter 25. Das Produkt C wird durch den Düsenstock 22 aus dem Schüttgutstrom 27 ausgelenkt und gelangt in den Aufnahmebehälter 26. Die Aufnahmebehälter 24, 25, 26 sind auf den Bodenförderern 10, 11 angeordnet (Fig. 1).Under the illuminating device 17 there are each other in the detection plane oppositely arranged two nozzle assemblies 22, 23, which with compressed air from e.g. 3 - 6 bar pressure can be applied. The compressed air can be cooled to e.g. 1 - 3 ° K be below ambient temperature or uncooled. The nozzles are strung together. The nozzle diameter can be 0.8 to 6 mm be. The nozzle blocks 22, 23 are driven in opposite directions, so with one sorting process results in three product qualities of different shades of gray. The product B falls into a receptacle 24 in free fall. The product A is deflected from the bulk material flow 27 by the nozzle assembly 23 and falls into the receptacle 25. The product C is discharged through the nozzle assembly 22 the bulk material flow 27 deflected and reaches the receiving container 26. Die Receptacles 24, 25, 26 are arranged on the floor conveyors 10, 11 (Fig. 1).

Fig. 4 zeigt eine Zellenradschleuse 7, mittels derer insbesondere die Ausschleussicherheit bei kleinen Schüttgutobjekten erhöht wird. Bei diesen besteht das Problem, daß im Vergleich zu größeren Objekten andere Fallgeschwindigkeitsverhältnisse vorliegen. Daher muß der Betrachtungs- und Trennbereich für kleine Objekte möglichst klein gestaltet werden. Da aufgrund der großen Fraktion die geometrischen Abmessungen der Objekte nicht verkleinert werden können, wird nach der Erfindung die Fallgeschwindigkeit harmonisiert. Hierzu ist die Zellenradschleuse 7 nach Fig. 4 besonders geeignet. Diese besteht aus zwei gegenläufig rotierenden Bürsten 29, 30, die koaxial zueinander angeordnet sind und von zwei gegenläufigen Pendelhubantrieben 31, 32 über einen Frequenzgleichrichter angetrieben werden.Fig. 4 shows a rotary valve 7, by means of which in particular the Rejection security for small bulk objects is increased. With these there is the problem that compared to larger objects others Fall speed ratios exist. Therefore, the viewing and Separation area for small objects can be made as small as possible. Because due the geometrical dimensions of the objects do not affect the large fraction can be reduced, the fall speed according to the invention harmonized. The cellular wheel sluice 7 according to FIG. 4 is particularly suitable for this. This consists of two counter-rotating brushes 29, 30, which are coaxial are arranged to each other and by two counter-rotating pendulum lifting drives 31, 32 are driven by a frequency rectifier.
