Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Sortieren von Abfallstoffen, insbesondere Kunststoffabfällen gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a device for sorting waste materials, especially plastic waste according to the preamble of claim 1.

Bekannte Trenn- bzw. Sortiervorrichtungen stoßen sehr bald an ihre Grenzen, was die zu sortierende Menge pro Zeiteinheit betrifft. So sind zum Beispiel sogenannte Drehteller aus der AT 402.165 bekannt, bei denen die Abfallstoffe einzeln dem Drehteller zugeführt werden und sich an dessen Rand positionieren um dann an entsprechender Stelle ausgeblasen zu werden. Eine Erhöhung der Sortierleistung kann bei dieser Art von Sortiervorrichtung nur dadurch erreicht werden, daß die Drehzahl des Drehtellers erhöht wird oder aber dessen Radius. Beide Schritte sind problematisch, da die räumliche Ausdehnung der Maschine unproportional schneller wächst als die Leistungssteigerung beim Sortieren der Abfallstoffe und sehr schnell Unterbringungsprobleme am Standort auftreten. Durch die Erhöhung der Drehzahl kommt es andererseits zu Ungenauigkeiten bei der Sortierung.Known separation or sorting devices come up very soon to its limits what the amount to be sorted per unit of time concerns. For example, so-called turntables from AT 402,165 known, in which the waste materials individually the Turntable are fed and position themselves on the edge to be blown out at the appropriate point. A Sorting performance can increase with this type of Sorting device can only be achieved in that the speed of the turntable is increased or its radius. Both Steps are problematic because of the spatial extent of the Machine grows disproportionately faster than that Performance increase in sorting the waste and very Housing problems quickly arise. Through the On the other hand, increasing the speed leads to inaccuracies when sorting.

Weiters sind Förderbänder aus Gummi bekannt, die die auszusortierenden Abfallstoffe transportieren und wo die Sortierung durch Stoßen oder Blasen der Abfallstoffe über die Seitenkanten des Förderbandes. Dies hat jedoch den Nachteil, daß nicht die gesamte Breite des Förderbandes genutzt werden kann, da zwischen den auszusortierenden Stücken und der Stoß- oder Blasvorrichtung keine anderen Abfallstücke liegen dürfen. Um die Sortierleistung zu erhöhen muß somit die Länge des Förderbandes unproportional stärker erhöht werden.Furthermore, conveyor belts made of rubber are known, which transport waste to be sorted out and where the Sorting by bumping or blowing the waste materials over the Side edges of the conveyor belt. However, this has the disadvantage that not the entire width of the conveyor belt can be used because between the pieces to be sorted out and the joint or No other pieces of waste may lie on the blowing device. To the Sorting performance must therefore increase the length of the conveyor belt be increased disproportionately more.

Es sind auch Förderbänder aus Gummi bekannt, wo die Abfallstoffe nach dem Ende des Förderbandes im Fallen in die gewünschte Richtung geblasen werden. Dies hat jedoch ebenfalls den Nachteil, daß am Ende des Förderbandes nur ein begrenzter Raum für die Anordnung von Ausblasdüsen und für die Behälter zur Aufnahme der aussortierten Abfallstücke zur Verfügung steht, womit die Sortierleistung dieser Bänder sehr gering ist. Rubber conveyor belts are also known where the Waste materials after the end of the conveyor belt falling into the the desired direction. However, this also has the disadvantage that only a limited at the end of the conveyor belt Space for the arrangement of blow-out nozzles and for the containers for The sorted waste pieces are available, with which the sorting performance of these belts is very low.

Ziel der vorliegenden Erfindung ist daher eine Vorrichtung der eingangs erwähnten Art, die die erwähnten Nachteile vermeidet und eine hohe Sortierrate bei geringem Flächenbedarf der Sortiervorrichtung gewährleistet.The aim of the present invention is therefore a device of the type mentioned at the beginning, which avoids the disadvantages mentioned and a high sorting rate with a small footprint of the Sorting device guaranteed.

Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention, this is due to the characteristic features of claim 1 achieved.

Durch die Verwendung eines Förderbandes mit gitterartiger Struktur und der Anordnung der Ausblasdüsen unterhalb des Förderbandes kann die gesamte Breite des Förderbandes zum Sortieren ausgenutzt werden, da die Ausblasdüsen auch entlang der gesamten Breite des Förderbandes angeordnet werden können. Ein doppelt so breites Förderband bewirkt somit eine doppelt so hohe Sortierleistung.By using a conveyor belt with a grid-like Structure and arrangement of the exhaust nozzles below the Conveyor belt can cover the entire width of the conveyor belt Sorting can be exploited because the exhaust nozzles also along the entire width of the conveyor belt can be arranged. On Conveyor belt twice as wide thus causes twice as high Sorting performance.

Durch die Merkmale des Anspruchs 2 ergibt sich der Vorteil, daß eine exakte Ansteuerung der auszusortierenden Elemente erfolgen kann, da die Ausblasdüsen nur wenige Millimeter unterhalb jener Fläche angeordnet werden können, auf der die auszusortierenden Abfallstoffe liegen. Bei einer Erhöhung der Förderbandgeschwindigkeit kann somit trotzdem eine hohe Genauigkeit bei der Sortierung erzielt werden.The features of claim 2 give the advantage that an exact control of the elements to be sorted out can be done because the blow-out nozzles are only a few millimeters can be arranged below the surface on which the waste materials to be sorted out. With an increase in Conveyor belt speed can still be high Sorting accuracy can be achieved.

Durch die Merkmale des Anspruchs 3 ergibt sich der Vorteil, daß die angeblasenen Abfallstücke direkt auf die Abfördereinrichtung geblasen werden können und dann weiter verteilt werden können, wobei die örtlichen Gegebenheiten nicht relevant sind. So können zum Beispiel, je nach aussortierten Stoffe, die verschiedenen Behälter in unterschiedlichen Räumen stehen bzw. können die aussortierten Stoffe direkt einer Weiterverarbeitungsvorrichtung zugeführt werden, ohne daß eine Zwischenspeicherung notwendig wäre.The features of claim 3 give the advantage that the blown waste directly on the Abfördereinrichtung can be blown and then continue can be distributed, but the local conditions are not are relevant. For example, depending on the sorted out Fabrics, the different containers in different rooms the sorted materials can or can be directly one Processing device can be supplied without a Caching would be necessary.

Anspruch 4 ermöglicht eine kompakte Bauweise der erfindungsgemäßen Vorrichtung, die sehr platzsparend eingesetzt werden kann. Claim 4 enables a compact design of the Device according to the invention, which is used in a very space-saving manner can be.

Durch die Merkmale des Anspruchs 5 ergibt sich der Vorteil, daß die erfindungsgemäße Vorrichtung unempfindlich Ungenauigkeiten der Ausblasevorrichtungen und unterschiedlichen Gewichten der Abfallstücke ist. Wird ein Abfallstück nicht exakt angeblasen bzw. variieren die Gewichte der Abfallstücke in einer gewissen Bandbreite, so kann es passieren, daß die ausgeblasenen Abfallstücke nicht exakt auf der Austragevorrichtung zu liegen kommen. Durch die erfindungsgemäßen Fangvorrichtungen werden die Abfallstücke jedoch in jedem Fall auf die Austragevorrichtung befördert, selbst wenn die Flugbahn der Abfallstücke zu kurz oder zu weit ist.The features of claim 5 result in the advantage that the device according to the invention is insensitive Inaccuracies of the blowing devices and different Weighting of the pieces of waste. If a piece of waste is not exactly blown or vary the weights of the waste pieces in one certain range, it can happen that the blown out Waste pieces do not lie exactly on the discharge device come. By the safety devices according to the invention However, pieces of waste always on the discharge device transported even if the trajectory of the pieces of waste is too short or is too far.

Im folgenden erfolgt nun eine detaillierte Beschreibung eines Ausführungsbeispieles anhand von Zeichnungen. Dabei zeigt

    • In Fig. 1 ist über einem Förderband 1 ein Sensor 2 angeordnet, an dessen Seiten Lampen 3 angebracht sind, die Licht unterschiedlicher Wellenlänge ausstrahlen. Auf dem Förderband 1 befinden sich Abfallstoffe 4, insbesondere Kunststoffabfälle wie zum Beispiel Hohlkörper aus PVC, Polyäthylen oder Kunstoffolien etc.. In Förderrichtung 5 dem Sensor 2 nachgeordnet sind quer zur Förderrichtung Austragevorrichtungen 6, wie zum Beispiel Förderbander, angeordnet, die entlang ihrer Förderrichtung im Bereich des Förderbandes 1 von im Querschnitt im wesentlichen uförmigen Fangvorrichtungen 7 umgeben sind.In FIG. 1, a sensor 2 is above a conveyor belt 1 arranged, on the sides of which lamps 3 are attached, the light emit different wavelengths. On the conveyor belt 1 there are waste materials 4, in particular plastic waste such as For example, hollow bodies made of PVC, polyethylene or plastic films etc. In the conveying direction 5 the sensor 2 are arranged transversely to Delivery direction discharge devices 6, such as Conveyor belts, which are arranged along their conveying direction in the Area of the conveyor belt 1 of substantially U-shaped in cross section Safety devices 7 are surrounded.

    In Förderrichtung 5 vor den Austragevorrichtungen 6 sind unterhalb des oberen Trums 8 und oberhalb des unteren Trums 9 des Förderbandes 1 Ausblasedüsen 10 so angeordnet, daß ihre Ausblaserichtung 11 nach oben in Richtung Austragevorrichtung 6 gerichtet ist.In the conveying direction 5 in front of the discharge devices 6 below the upper run 8 and above the lower run 9 of the Conveyor belt 1 blowing nozzles 10 arranged so that their Blow-out direction 11 upwards in the direction of discharge device 6 is directed.

    Die Funktionsweise der erfindungsgemäßen Sortiervorrichtung ist dabei wie folgt:The operation of the sorting device according to the invention is as follows:

    Die Abfallstücke 4 werden ungeordnet auf vor dem Sensor 2 auf das Förderband 1 aufgebracht. Der Sensor 2 erkennt aufgrund des von den Abfallstücken 4 reflektierten Anteils des von den Lampen 3 abgestrahlten Lichtes, um was für eine Art von Abfallstoff (Polyäthylen, PVC, Tetra Paks, Kunststoffhohlkörper, etc) es sich handelt. Weiters ist es auch möglich, die Abfallstoffe aufgrund der Farben zu unterscheiden.The waste pieces 4 are disordered in front of the sensor 2 applied to the conveyor belt 1. The sensor 2 detects of the portion reflected by the waste pieces 4 of the Lamps 3 emitted light to what kind of Waste material (polyethylene, PVC, Tetra Paks, plastic hollow body, etc) it is. It is also possible that Differentiate waste based on color.

    Nach erfolgter Erkennung sind die jeweiligen Positionen der Abfallstücke 4 auf dem Transportband bekannt und beim passieren der Ausblasedüsen 10 werden genau definierte Luftstrahlen von unten durch das gitterartige Förderband 1 auf die jeweiligen auszusortierenden Abfallstücke 4 geblasen. Durch den Impuls des Luftstrahles werden die Abfallstücke 4 in Richtung der Austragevorrichtungen 6 bewegt. Die Fangvorrichtungen 7 bewirken, daß die Abfallstücke 4 nur ungefähr in Richtung der Austragevorrichtung 6 bewegt werden müssen und diese trotzdem nicht verfehlen.After recognition, the respective positions are the Waste pieces 4 known on the conveyor belt and when passing the blow-out nozzles 10 are precisely defined air jets from below through the grid-like conveyor belt 1 to the respective blown out waste pieces 4 blown. By the impulse of Air jets are the waste pieces 4 in the direction of Discharge devices 6 moves. The safety devices 7 cause that the waste pieces 4 only approximately in the direction of Discharge device 6 must be moved and this nevertheless do not miss.

    Jede Austragevorrichtung 7 ist für eine Art von Abfallstoff vorgesehen. Je mehr unterschiedliche Arten an Abfallstoffen zu sortieren sind, desto mehr Austragevorrichtungen sind vorzusehen.Each discharge device 7 is for one type of waste intended. The more different types of waste materials too are sorted, the more discharge devices are to be provided.
