The invention concerns a sorting machine (1) which sorts, according to size, the components of a mixture such as rubbish, initially using a bucket-type sieve (2). The contents of the buckets (12) are subsequently blown out by a blower (8), thus separating out the lighter components of the mixture in the cups (12).

Description

Sortiervorrichtung mit Becher-oder Taschensiebwerk Sorting device with cup or pocket sieve

Beschreibung:Description:

Die Erfindung betrifft eine Sortiervorrichtung insbesondere zum Auftrennen und Sortieren von Müllgemischen nach dem Oberbegriff des Anspruchs 1.The invention relates to a sorting device in particular for separating and sorting waste mixtures according to the preamble of claim 1.

Zum Sortieren und Auftrennen von Stoffgemischen mit Bestandteilen verschiedener Größe und Formen mittels eines Becher- oder Taschensiebwerks sind bereits verschiedene Vorrichtungen bekannt geworden.Various devices have already become known for sorting and separating mixtures of substances with components of different sizes and shapes by means of a cup or pocket screen.

So ist beispielsweise, allerdings auf einem der MüllSortierung völlig artfremden Gebiet, in der US-A 2 116 006 eine Vorrichtung zur Sortierung von Hopfen beschrieben worden. Diese Vorrichtung weist ein umlaufendes Förderband mit einer Vielzahl von Taschen auf, das dazu dient, den Hopfen vom Hopfenstil zu trennen. Die aus den Taschen herausragenden Hopfenstile werden hierbei von einer Bürste abgeschert und weggeschleudert. Die übrigen feineren Hopfenteile fallen bei der Umkehr des Bandes, bei der die Öffnung der Taschen nach unten gekehrt wird, aus den Taschen in einen dafür vorgesehenen Behälter.For example, a device for sorting hops has been described in US-A-2 116 006, however, in a field that is completely alien to waste sorting. This device has a rotating conveyor belt with a plurality of pockets, which serves to separate the hops from the hop style. The hop styles sticking out of the pockets are sheared off by a brush and flung away. The other finer hop parts fall out of the pockets into a container provided for this purpose when the band is reversed, in which the opening of the pockets is turned downwards.

Desweiteren ist aus der EP 0 265 669 eine Sortiermaschine mit einem Bechersiebwerk bekannt geworden, die unter anderem a ~h zur Sortierung von Müllgemischen geeignet ist. Diese Vorrichtung weist ein mit Becher versehenes Förderband auf, das quer zur Förderrichtung des einzubringenden Stoffgemisches umläuft. Die in den Bechern festgehaltenen feinkörnigeren Güter werden entlang einer ansteigenden Flanke des Förderbandes nach oben transportiert, wobei die gröberen Bestandteile des Gemisches aufgrund der Steigung des Förderbandes nach unten rutschen und dabei ständig umgewälzt werden. Über eine obere Umlenkwalze werden die mit dem Förderband verbundenen Becher umgelenkt und zur Entleerung herumgedreht. Dabei ist das Förderband quer zu seiner Umlaufrichtung und entlang der ursprünglichen Transportrichtung des Sortiergutes so geneigt, daß die nicht von den Bechern aufgenommenen gröberen Bestandteile in dieser ursprünglichen Transportrichtung weitertransportiert werden.Furthermore, from EP 0 265 669 a sorting machine with a cup screen has become known, which among other things is suitable for sorting waste mixtures. This device has a conveyor belt provided with a cup, which rotates transversely to the conveying direction of the substance mixture to be introduced. The fine-grained goods held in the cups are along a rising flank of the conveyor belt is transported upwards, the coarser constituents of the mixture sliding downward due to the incline of the conveyor belt and being constantly circulated. The cups connected to the conveyor belt are deflected by an upper deflecting roller and turned around for emptying. The conveyor belt is inclined transversely to its direction of rotation and along the original direction of transport of the goods to be sorted so that the coarser components not taken up by the cups are transported further in this original direction of transport.

Mit einer solchen Vorrichtung können sehr effektiv Bestandteile eines Gemisches getrennt werden, die sich aufgrund ihrer Ausmaße und Körnigkeit unterscheiden. Allerdings kann eine solche Vorrichtung keine Bestandteile des Sortierguts trennen, die vergleichbare Ausmaße, jedoch ein unterschiedliches Gewicht aufweisen. Eine solche Trennung wäre äußerst vorteilhaft, da hiermit beispielsweise Kunststo fteile von Stein- oder Metallgütern separiert werden könnten.With such a device components of a mixture can be separated very effectively, which differ in their dimensions and granularity. However, such a device cannot separate components of the goods to be sorted which have comparable dimensions but a different weight. Such a separation would be extremely advantageous, since it could be used to separate plastic parts from stone or metal goods, for example.

Auch die Auftrennung von folienartigenAlso the separation of film-like ones

KunstStoffbestandteilen gegenüber Kunststoffbehältnissen gleicher Größe, wie Becher oder Dosen, kann mit einer Vorrichtung der genannten Art nicht bewerkstelligt werden.Plastic components compared to plastic containers of the same size, such as cups or cans, can not be achieved with a device of the type mentioned.

Aufgabe der Erfindung ist es deshalb, eine Sortiervorrichtung vorzuschlagen, die ein Sortiergut nicht nur aufgrund seiner Ausmaße oder Kδrnigkeit auftrennt, sondern zusätzlich eine Sortierung nach Gewicht der einzelnen Bestandteile des Sortierguts erlaubt. Diese Aufgabe wird ausgehend von einer Sortiermaschine der einleitend bezeichneten Art erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserung der im Hauptanspruch angegebenen Sortiervorrichtung möglich.The object of the invention is therefore to propose a sorting device which not only separates a product to be sorted on the basis of its dimensions or granularity, but also permits sorting by weight of the individual components of the product to be sorted. Starting from a sorting machine of the type described in the introduction, this object is achieved according to the invention by the characterizing features of claim 1. The measures listed in the subclaims enable advantageous further developments and improvement of the sorting device specified in the main claim.

Demgemäß wird eine Sortiervorrichtung mit einem auf einer ' Fördereinrichtung angeordneten Becher- oder Taschensiebwerk zur Sortierung des Sortiergutes aufgrund seiner unterschiedlichen Ausmaße mit einer Ausblasvorrichtung zur weiteren Auftrennung des in den Bechern oder Taschen aussortierten Sortiergutes versehen. Hierdurch wird es möglich, schwere Bestandteile des Sortiergutes von den leichteren Bestandteilen, die durch die Ausblasvorrichtung entfernt werden, zu trennen.Accordingly, a sorting device with a cup or pocket sieve arranged on a conveyor device for sorting the sorted goods is provided due to its different dimensions with a blow-out device for further separation of the sorted goods in the cups or pockets. This makes it possible to separate heavy components of the goods to be sorted from the lighter components which are removed by the blow-out device.

Dabei ist es besonders zweckmäßig, die Ausblasvorrichtung zwischen der Füll- und der Entleerungszone der Becher anzubringen. Hierdurch können die zur Sortierung verwendeten Becher ausgeblasen werden, ohne daß es zusätzlicher Behältnisse für das Sortiergut innerhalb der Ausblasvorrichtung bedarf.It is particularly expedient to attach the blow-out device between the filling and the emptying zone of the cups. As a result, the cups used for sorting can be blown out without the need for additional containers for the sorted material within the blow-out device.

Besonders vorteilhaft ist eine Anordnung in Höhe der Drehachse der oberen Umlenkwalze des Bechersiebwerkes. Eine solche Anordnung hat zur Folge, daß die Ausblasvorrichtung in einen nahezu rechtwinklig geneigten Becher bläst und somit bei kleinem Energieaufwand mit vergleichsweise niedrigem Luftdruck und entsprechend schwachem Luftstrom die leichten Bestandteile des in den Bechern befindlichen Sortiergutes aus diesen heraus befördern kann.An arrangement at the level of the axis of rotation of the upper deflecting roller of the cup screening machine is particularly advantageous. Such an arrangement has the result that the blow-out device blows into an almost right-angled cup and can thus convey the light components of the sorted material from the cups with little energy expenditure with comparatively low air pressure and correspondingly weak air flow.

Als vorteilhaft hat sich eine Ausstattung der Ausblasvorrichtung mit einem Blasrohr und einer Auffangrinne empfohlen. Dadurch kann, insbesondere wenn das Blasrohr parallel zu einer Becherreihe angeordnet und mit radialen Öffnungen zur Erzeugung des zum Ausblasen notwendigen Luftstroms versehen ist, die Ausblasvorrichtung starr innerhalb der Sortiermaschine angeordnet werden. Eine solche Ausblasvorrichtung bearbeitet entlang einer Geraden die gesamte Breite des förderbandartigen Bechersiebwerks, ohne daß eine Luftdüse o. dgl. in Verbindung mit einer Auffangvorrichtung an den Bechern entlang hin- und hergeführt wird.It has been recommended to equip the blow-out device with a blow pipe and a gutter. As a result, the blow-out device can be rigid, in particular if the blow pipe is arranged parallel to a row of cups and is provided with radial openings for generating the air flow required for blowing out be arranged within the sorting machine. Such a blow-out device processes the entire width of the conveyor belt-type cup screen along a straight line, without an air nozzle or the like being moved back and forth along the cups in connection with a collecting device.

Zum Abtransport des in der Auffangrinne aufgefangenen Sortiergutes wird die Auffangrinne gegenüber einer horizontalen Ebene geneigt, so daß das Sortiergut entlang dieser Neigung heruntergleiten kann.In order to remove the sorting material caught in the collecting trough, the collecting trough is inclined relative to a horizontal plane, so that the sorting material can slide down along this inclination.

Zur Verbesserung des Abtransports des aufgefangenen Sortiergutes kann die Auffangrinne mit einer eigens dafür bestimmten Transportvorrichtung versehen werden. Denkbar wäre hierbei ein Antrieb, der die Auffangrinne in eine Vibrations¬ oder Schüttelbewegung versetzt und somit einen Gleitvorgang wie oben angeführt in Gang setzen oder unterstützen kann.To improve the removal of the collected sorting material, the collecting trough can be provided with a specially designed transport device. A drive would be conceivable that would set the gutter in a vibrating or shaking motion and thus could start or support a sliding process as mentioned above.

Eine weitere Möglichkeit, den Abtransport des Sortiergutes aus der Auffangrinne zu bewerkstelligen, ist durch das Anbringen eines Förderbandes am Boden der Auffangrinne gegeben.Another way of transporting the sorted goods out of the collecting trough is by attaching a conveyor belt to the bottom of the collecting trough.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert.An embodiment of the invention is shown in the drawing and explained in more detail in the following description.

In Fig. 1 ist eine Sortiermaschine 1 gezeigt, wie sie prinzipiell aus der EP 0 265 669 Bl der Anmelderin bekannt ist. Auf den Inhalt dieser Patentschrift wird hiermit zur Beschreibung der vorliegenden Erfindung ausdrücklich Bezug genommen.1 shows a sorting machine 1 as is known in principle from the applicant's EP 0 265 669 B1. Reference is hereby expressly made to the content of this patent specification to describe the present invention.

Diese Sortiermaschine 1 weist ein förderbandartig umlaufendes Bechersiebwerk 2 auf. Hinter dem Bechersiebwerk 2 befindet sich eine Zulaufrinne 3. Das Bechersiebwerk wird über eine untere 4 und eine obere 5 Umlenkwalze geführt. In Verlängerung der Drehachse 6 der oberen Umlenkwalze befindet sich ein Elektromotor 7 zum Betrieb des Bechersiebwerks 2.This sorting machine 1 has a cup sieve 2 rotating around in the manner of a conveyor belt. An inlet channel 3 is located behind the cup screen 2. The cup screen is guided over a lower 4 and an upper 5 deflection roller. An extension of the axis of rotation 6 of the upper deflecting roller is an electric motor 7 for operating the cup screen 2.

Auf Höhe der Drehachse 6 befindet sich eine Ausblasvorrichtung 8. Diese besteht aus einem Ausblasrohr 9 und einer Auffangrinne 10 die gesamte Vorrichtung ist auf einem Rahmen 11 montiert.At the level of the axis of rotation 6 there is a blow-out device 8. This consists of a blow-out pipe 9 and a collecting channel 10. The entire device is mounted on a frame 11.

Über die Zulaufrinne 3 wird das Sortiergut der Sortiermaschine 1 zugeführt. Das Bechersiebwerk 2 ist so ausgebildet, daß umlaufende Becher 12 bei ihrer Bewegung auf die obere Umlenkwalze 5 nach oben geführt und gleichzeitig um ungefähr 90° in eine waagerechte Position geschwenkt werden. Auf der Höhe der Drehachse 6 der oberen Umlenkwalze 5 befinden sich die Becher also in einer idealen Position, um mit sehr geringem Energieaufwand leichte Bestandteile des in den Becher befindlichen Sortiergutes aus den waagerecht geneigten Bechern herauszublasen. Über das Ausblasrohr 9 wird Druckluft zugeführt und in die Becher 12 eingeblasen. Die Strömungsrichtung der Luft ist durch die vom Ausblasrohr 9 ausgehenden Pfeile L gekennzeichnet. In der Auffangrinne 10 wird das ausgeblasene Gut gesammelt. Entsprechend der Neigung der Auffangrinne 10 gleitet das gesammelte Gut innerhalb der Auffangrinne vorwärts und kann beispielsweise in einem nicht dargestellten Behälter abgefüllt werden.The material to be sorted is fed to the sorting machine 1 via the feed trough 3. The cup sieve 2 is designed such that rotating cups 12 are guided upwards as they move onto the upper deflecting roller 5 and at the same time are pivoted by approximately 90 ° into a horizontal position. At the level of the axis of rotation 6 of the upper deflecting roller 5, the cups are thus in an ideal position in order to blow out light components of the items to be sorted from the horizontally inclined cups with very little energy expenditure. Compressed air is supplied via the blow-out pipe 9 and blown into the cup 12. The direction of flow of the air is indicated by the arrows L emerging from the blow-out pipe 9. The blown-out material is collected in the gutter 10. According to the inclination of the gutter 10, the collected goods slide within the Collecting channel forward and can for example be filled in a container, not shown.

In Fig. 2 ist ein schematischer Querschnitt durch eine solche Maschine während des Betriebs dargestellt. Das gröbere Sortiergut 13 wälzt sich durch seine Schwerkraft ständig entgegen der Umlaufrichtung des Bechersiebwerks 2 nach unten. Das in den Bechern 12 befindliche feinere Sortiergut 14 wird nach oben geführt und passiert in etwa auf der Höhe der Drehachse 6 der oberen Umlenkwalze 5 die Ausblasvorrichtung 8. Das nach dem Ausblasen in den Bechern 12 verbliebene schwerere Sortiergut 15 wird um die obere Umlenkwalze 5 herumgeführt und anschließend aus den Bechern 12 zur weiteren Verarbeitung ausgeleert. Die Ausblasvorrichtung 8 ist in dem mit "Z" gekennzeichneten Bildausschnitt in Fig. 3 vergrößert dargestellt.2 shows a schematic cross section through such a machine during operation. The coarser sorting material 13 constantly rolls downward against the direction of rotation of the cup screen 2 due to its gravity. The finer sorting material 14 located in the cups 12 is guided upward and passes the blow-out device 8 approximately at the height of the axis of rotation 6 of the upper deflecting roller 5. The heavier sorting material 15 remaining in the cups 12 after blowing out is guided around the upper deflecting roller 5 and then emptied out of the cups 12 for further processing. The blow-out device 8 is shown enlarged in the image section marked "Z" in FIG. 3.

Im einzelnen ist in Fig. 3 das Ausblasrohr 9 und eine radial angeordnete Ausblasöffnung 16 zu sehen. Aus der Ausblasöffnung 16 entströmt die über das Ausblasrohr 9 zugeführte Druckluft. Der Luftstrom außerhalb des Ausblasrohrs 9 im Anschluß an die AusblasÖffnung 16 ist durch Pfeile L veranschaulicht. Er trifft auf einen Becher 12, der aufgrund oben genannter Umstände nahezu waagrecht geneigt ist, in der Nähe der in dieser Neigung oberen Seitenwand 17 des Bechers 12. Am Boden 18 des Bechers wird der Luftstrom L umgelenkt, so daß er schließlich entlang der unteren Seitenwand 19 des Bechers 12 diesen wieder verläßt. Beim Verlassen des Bechers 12 nimmt der Luftström L leichtere, nicht dargestellte Partikel des im unteren Bereich des Bechers 12 vornehmlich auf der Seitenwand 19 liegenden Sortiergutes mit. Das mitgenommene leichte Sortiergut fällt anschließend aufgrund seines Gewichts entlang der Pfeilrichtung 20 in die Auffangrinne 10. Aus der Auffangrinne 10 kann das aussortierte Gut durch verschiedene Maßnahmen abtransportiert werden. Eine Lösung hierzu bietet ein Förderband 21 oberhalb des Bodens 22 der Auffangrinne 10. Das Förderband 21 nimmt das aussortierte Gut auf und entfernt es aus der Auffangrinne 10 in einer seinem Umlaufsinn entsprechenden Transportrichtung, die senkrecht zur Papierebene steht.The blow-out pipe 9 and a radially arranged blow-out opening 16 can be seen in detail in FIG. 3. The compressed air supplied via the blow-out pipe 9 flows out of the blow-out opening 16. The air flow outside the blow-out pipe 9 following the blow-out opening 16 is illustrated by arrows L. It encounters a cup 12, which is inclined almost horizontally due to the above-mentioned circumstances, in the vicinity of the upper side wall 17 of the cup 12 at this inclination 19 of the cup 12 leaves it again. When leaving the cup 12, the air flow L takes lighter particles, not shown, of the items to be sorted, which are located in the lower region of the cup 12, primarily on the side wall 19. Because of its weight, the light sorting material that is taken along then falls into the collecting trough along the direction of the arrow 20. The sorted out material can be removed from the collecting trough 10 by various measures. A solution to this offers one Conveyor belt 21 above the bottom 22 of the collecting trough 10. The conveyor belt 21 picks up the sorted material and removes it from the collecting trough 10 in a transport direction corresponding to its direction of rotation, which is perpendicular to the paper plane.
