Abstract

A sorting machine which serves for treatment of mixtures of refuse, especially household rubbish, trade waste, industrial waste, refuse from demolition, waste from building sites, and also waste from wood or the like. To achieve a drum-like motion, a mixture of useful material is supplied to a conveyor belt which is inclined transversely to the direction of transport, the conveyor belt having the shape of part of a cylindrical shell. For the production of a screen effect, the screen conveyor belt is provided with screen pockets on its surface, so that fine material falling into the screen pockets is transported in the longitudinal direction of the screen conveyor belt, and coarse material is transported in the transverse direction of the screen conveyor belt, and thereby they are separated.

Description

Die Erfindung betrifft eine Sortiermaschine, insbesondere für die Sortierung von Müllgemischen insbesondere Hausmüll, Gewerbemüll, Industriemüll, Müll aus Abbrüchen, Baustellenabfällen, sowie Holzabfälle o. dgl. nach dem Oberbegriff des Anspruchs 1.The invention relates to a sorting machine, in particular for the sorting of waste mixtures, in particular domestic waste, commercial waste, industrial waste, waste from demolitions, construction site waste, and wood waste or the like. According to the preamble of claim 1.

Aus der älteren Anmeldung der Anmelderin DE 34 15 090 Al ist eine Sortieranlage zur Wertstoffsortierung bekannt geworden. Eine hierin enthaltene Sortiermaschine besteht aus einem vibrierenden, quer zur Förderrichtung geneigten und in Förderrichtung ansteigenden Förderband zur Trennung von körperförmigen von flächenhaftem Sortiergut. Ein Siebvorgang mittels Maschen findet nicht statt.A sorting system for sorting valuable materials has become known from the earlier application of the applicant DE 34 15 090 A1. A sorting machine contained therein consists of a vibrating conveyor belt, which is inclined transversely to the conveying direction and rises in the conveying direction, for separating body-shaped from flat sorting goods. A sieving process using meshes does not take place.

Das Auftrennen von Trockenmüll und das Sortieren in einzelne, wiederverwertbare Bestandteile bereitet wegen der starken Verschlungenheit des anfallenden Mülls große Probleme. Insbesondere neigen sämtliche Bauarten von Sieben mehr oder weniger stark zu Verstopfungen, da sich in den Siebmaschen einzelne Bestandteile verklemmen können. Dies gilt insbesondere für Materialien ohne feste Struktur und Gestalt, wie Strümpfe, Stoffreste, Schnüre und Bänder die zum Teil durch die Siebmaschen hindurchfallen, zum Teil durch übrigen Müll zurückgehalten werden. Hierdurch verkleinert sich automatisch die Maschenweite.The separation of dry waste and the sorting into individual, reusable components causes great problems due to the high degree of entanglement of the waste. In particular, all types of screens tend to clog to a greater or lesser extent, since individual components can become jammed in the screen mesh. This applies in particular to materials without a fixed structure and shape, such as stockings, fabric remnants, cords and ribbons that partly fall through the sieve mesh and are partly retained by other waste. This automatically reduces the mesh size.

Siebvorrichtungen mit Maschen bzw. Siebformen jeglicher Art sind deshalb bei der Müllverarbeitung nur bedingt und mit besonderen Maßnahmen einsatzfähig. Die Wirkungsweise zur Auftrennung von Materialien ist deshalb mehr oder weniger beschränkt. Trommelsiebe haben zwar den Vorteil, daß das eingebrachte Material ständig durch die Drehbewegung übereinander geworfen und damit auseinander gezogen wird. Für die Müllsortierung eignen sich jedoch Trommelsiebe nicht, da die Maschen ebenfalls stark zur Verstopfung mit Müllbestandteilen neigen. Außerdem erfordert die Trag- und Antriebs-Konstruktion von Trommelsieben axialen Raum, was ggf. unerwünscht ist.Screening devices with meshes or screen shapes of any kind are therefore only of limited use in waste processing and can be used with special measures. The mode of action for separating materials is therefore more or less limited. Drum sieves have the advantage that the material introduced is constantly thrown over one another by the rotary movement and thus pulled apart. However, drum screens are not suitable for waste sorting, since the meshes also tend to clog with waste components. In addition, the support and drive construction of drum screens requires axial space, which may be undesirable.

Aus dem völlig artfremden Gebiet der Sortierung von Hopfen ist aus der US-PS 2 116 006 eine Vorrichtung bekannt geworden, die aus einem umlaufenden Förderband besteht, welches eine Vielzahl von Taschen aufweist. Der Trennvorgang des Hopfens vom Hopfenstiel geschieht dadurch, daß eine Bürste die aus den Taschen herausragenden Hopfenstiele abschert und wegschleudert. Die übrigen Hopfenteile fallen bei Umkehr des Bandes in einen vorgesehenen Behälter.From the completely alien field of sorting hops, a device has become known from US Pat. No. 2,116,006 which consists of a revolving conveyor belt which has a multiplicity of pockets. The process of separating the hops from the hops stalk occurs in that a brush shears the hops stalks sticking out of the pockets and throws them away. The remaining hop parts fall into a designated container when the tape is reversed.

Diese Vorrichtung ist zur Müllsortierung nicht geeignet, da ein Trennvorgang mittels einer Bürstenvorrichtung nicht möglich ist. Die Taschenform des Transportbandes hat darüber hinaus lediglich die Funktion einer Haltevorrichtung zur Abstreifung der darüber hinaus stehenden Stiele.This device is not suitable for sorting waste since a separation process using a brush device is not possible. In addition, the pocket shape of the conveyor belt only has the function of a holding device for stripping off the stalks which are beyond.

Der Erfindung liegt die Aufgabe zugrunde, eine Sortiermaschine für die Müllverarbeitung zu schaffen, die vor allem ein möglichst verstopfungsfreies Trennen und Sortieren von Müllgemischen, insbesondere Hausmüll, Gewerbemüll, Industriemüll und den besonders schwer zu verarbeitenden Müll aus Bauabbrüchen, Baustellenabfälle sowie Abfälle aus Altholz erlaubt.The invention has for its object to provide a sorting machine for waste processing, which above all allows a clog-free separation and sorting of waste mixtures, in particular household waste, commercial waste, industrial waste and the particularly difficult to process waste from demolition, construction site waste and waste from waste wood.

Diese Aufgabe wird ausgehend von einer Sortiermaschine der einleitend bezeichnenden Art erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved on the basis of a sorting machine of the type described in the introduction by the characterizing features of claim 1.

In den Unteransprüchen sind weitere Maßnahmen zur zweckmäßigen und vorteilhaften Weiterbildung der im Hauptanspruch angegebenen Sortiermaschine angegeben.Further measures for the expedient and advantageous development of the sorting machine specified in the main claim are specified in the subclaims.

Die Erfindung arbeitet zunächst nach dem Prinzip des aufgeteilten Mengenstroms in der Längs- und Querrichtung einer Fördereinrichtung. Hierzu wird das zu sortierende Wertstoffgemisch auf einer Seite eines geneigten Förderbandes aufgegeben und kann durch Schwerkraft und/oder durch Vibrations- bzw. Schwingungsunterstützung das umlaufende Förderband quer zur Laufrichtung passieren. Ein Teil des Wertstoffgemisches fällt in die auf das Siebband aufgebrachte Siebtaschen und wird in Transport-­Längsrichtung der Fördereinrichtung so lange mitgenommen, bis die Siebtaschen an der Umlenkrolle umkippen. Die Siebtaschen stellen demnach ein Lochsieb dar, jedoch mit begrenzter Durchfallhöhe. Hierdurch ist das ganze Siebsystem praktisch verstopfungsfrei.The invention first works on the principle of the divided flow in the longitudinal and transverse directions of a conveyor. For this purpose, the mixture of recyclable materials to be sorted is placed on one side of an inclined conveyor belt and can pass the rotating conveyor belt transversely to the direction of travel by gravity and / or by vibration or vibration support. Part of the mixture of recyclable materials falls into the sieve pockets attached to the sieve belt and is carried along in the longitudinal direction of the conveying device until the sieve pockets on the deflection roller tip over. The sieve pockets therefore represent a perforated sieve, but with a limited drop height. This means that the entire screening system is practically free of blockages.

Erfindungsgemäß wird die Siebvorrichtung derart ausgestaltet, daß das Transportband im Bereich der Siebstrecke nach Art eines Trommelsiebs ausgebildet ist, d. h. das Transportband ist nach Art einer Zylindermantelfläche kreisförmig durchhängend geführt. Hierdurch wird das auf diesem trommelartigen Sieb transportierte Wertstoffgemisch ständig umgewälzt, was zur Auflockerung und Auftrennung der Bestandteile führt. Der trommelartige Effekt des normalerweise ebenen Transport-­Siebbandes wird dadurch erzielt, daß die Längsachsen der Umlenkwalzen höher gelagert sind, als der tiefste Punkt auf der Transport-Bearbeitungsebene. Durch diese Maßnahmen arbeitet die erfindungsgemäße Sortiermaschine mit den vorteilhaften Wirkungen eines Trommelsiebs ohne dessen Nachteile in Bezug auf die Verstopfungsneigung sowie der ungünstigen baulichen Länge in Kauf nehmen zu müssen. Die erfindungsgemäße Vorrichtung kann die zusätzliche axiale Länge gegenüber herkömmlichen Sieben im Ein- und Auslaufbereich voll nutzen.According to the invention, the screening device is designed in such a way that the conveyor belt in the area of the screening section is designed in the manner of a drum screen, ie the conveyor belt is guided in a circular, sagging manner in the manner of a cylinder jacket surface. As a result, the mixture of valuable materials transported on this drum-like sieve is constantly circulated, which leads to the loosening and separation of the constituents. The drum-like effect of the normally flat transport screen belt is achieved in that the longitudinal axes of the deflecting rollers are positioned higher than the lowest point on the transport processing plane. Through these measures the sorting machine according to the invention works with the advantageous effects of a drum screen without having to accept its disadvantages with regard to the tendency to blockage and the unfavorable structural length. The device according to the invention can fully utilize the additional axial length compared to conventional screens in the inlet and outlet area.

Besonders vorteilhaft ist weiterhin die erfindungsgemäße Ausbildung der Siebtaschen dergestalt, daß sich diese beim Umlenkvorgang über die obere Umlenkrolle selbständig öffnen und hierdurch ein einwandfreies Entleeren der Siebtasche ermöglicht wird. Jeweils eine, für zwei hintereinander folgenden Siebtaschen gemeinsame Rückwand wird beim Umlenkvorgang von einer Tasche weggeklappt, so daß eine Öffnung in diesem Bereich entsteht.Furthermore, the inventive design of the sieve pockets is particularly advantageous in such a way that they open automatically during the deflection process via the upper deflection roller and this enables the sieve pocket to be emptied properly. One back wall, common to two successive sieve pockets, is folded away from a pocket during the deflection process, so that an opening is created in this area.

Im Bereich der höher gelegenen seitlichen Kante (18) des Siebförderbands (11) ist die Aufgabevorrichtung (19) in Form einer Schütte mit Schwingantrieb (20) für das auf die Sortiermaschine aufzubringende Wertstoffgemisch (32) dargestellt. Auf der gegenüberliegenden niedrigen seitlichen Kante (21) ist die Austragsvorrichtung (22) für das Grobgut (29) dargestellt.In the area of the higher lateral edge (18) of the sieve conveyor belt (11), the feed device (19) is shown in the form of a chute with oscillating drive (20) for the mixture of recyclable materials (32) to be applied to the sorting machine. The discharge device (22) for the coarse material (29) is shown on the opposite low side edge (21).

Die Umlenkrollen (12 und 13) für das Siebförderband (11) sind in Bezug zur Anordnung und Länge des Siebförderbands derart angeordnet, daß sich im Bereich der Förderstrecke für das Transportgut ein Aufbau nach Art eines Trommelsiebs ergibt. Die Transportfläche für das Sortiergut bewegt sich deshalb entlang einer Zylindermantelfläche (23). Der Krümmungsradius dieser Zylindermantelfläche wird je nach zu behandelndem Material gewählt. Der trommelartige Aufbau im Transportbereich wird durch Höhersetzen der Längsachsen (24 bzw. 25) der Umlenkrollen (12 bzw. 13) gegenüber dem tiefsten Punkt (26) auf dem Siebförderband erreicht. Im Ausführungsbeispiel nach Fig. 1 ist die Längsachse (25) der Umlenkrolle (13) räumlich höher angeordnet als die Längsachse (24) der Umlenkrolle (12). Hierdurch ergibt sich der steile Anstieg des Siebförderbands (11) und damit der trommelartige Aufbau zur ständigen Umwälzung des darauf befindlichen Wertstoffgemisches.The deflection rollers (12 and 13) for the sieve conveyor belt (11) are arranged in relation to the arrangement and length of the sieve conveyor belt in such a way that a structure in the manner of a drum sieve results in the region of the conveyor line for the goods to be transported. The transport surface for the goods to be sorted therefore moves along a cylindrical surface (23). The radius of curvature of this cylindrical surface is selected depending on the material to be treated. The drum-like structure in the transport area is achieved by raising the longitudinal axes (24 or 25) of the deflection rollers (12 or 13) relative to the lowest point (26) on the screen conveyor belt. In the exemplary embodiment according to FIG. 1, the longitudinal axis (25) of the deflection roller (13) is arranged spatially higher than the longitudinal axis (24) of the deflection roller (12). This results in the steep rise of the sieve conveyor belt (11) and thus the drum-like structure for the constant circulation of the mixture of materials located thereon.

Der Antrieb der Umlenkrolle (13) und damit des Siebförderbands (11) ist mit dem Antriebsmotor (27) gekennzeichnet, wobei der Antrieb mittels eines Kettenantriebs (43) erfolgt, der vom Transportband (11) überdeckt ist.The drive of the deflection roller (13) and thus of the sieve conveyor belt (11) is identified by the drive motor (27), the drive being effected by means of a chain drive (43) which is covered by the conveyor belt (11).

Der Materialtransport quer zur Siebförderbandlängsrichtung (16), d. h. in Siebförderbandquerrichtung (17) erfolgt durch die Neigung des Siebförderbands (11) um den Winkel (α). Der Winkel (α) wird im Größenbereich zwischen 5 bis 20° ähnlich wie bei Trommelsieben gewählt. Er kann jedoch auch je nach Materialbeschaffenheit des zu sortierenden Wertstoffgemisches andere Werte einnehmen. Der Materialtransport wird demnach wie bei einem Trommelsieb mit materialumwälzenden Eigenschaften durch die Schwerkraft bewirkt. Zusätzlich oder alternativ kann auch ein Schwingantrieb bzw. ein Rüttelantrieb für das Siebförderband (11) vorgesehen sein.The material is transported transversely to the longitudinal direction of the conveyor belt (16), ie in the transverse direction of the conveyor belt (17), by the inclination of the conveyor belt (11) by the angle (α). The angle (α) is chosen in the size range between 5 to 20 ° similar to that of drum screens. However, it can also have different values depending on the material properties of the mixture of materials to be sorted. Material transport is therefore effected by gravity like a drum screen with material-circulating properties. Additionally or alternatively, an oscillating drive or a vibrating drive can also be provided for the sieve conveyor belt (11).

Die auf der gesamten Oberfläche des Siebförderbands (11) angebrachten Siebtaschen (14) bilden eine Art Lochsieb, in welche feineres Siebgut hineinfällt und in Siebförderbandlängsrichtung (16) weitertransportiert wird. Erst durch den Umlenkvorgang über die Umlenkrolle (13) fällt das Feingut (28) als gesonderte Sortierfraktion aus. Das für die Siebtaschen (14) zu große Material wird demgegenüber in Siebförderbandquerrichtung (17) weitertransportiert und in der Austragsvorrichtung (22) als Grobgut (29) ausgetragen. Um eine ausreichende Verweildauer des Wertstoffgemisches auf dem Siebförderband (11) zu gewährleisten, muß dieses eine gewisse Mindestbreite (B) aufweisen, welches der Länge einer Trommel-Siebeinrichtung einschließlich Tragkonstruktion entspricht. Die Breite (B) liegt in der Größenordnung von B∼4 m.The sieve pockets (14) attached to the entire surface of the sieve conveyor belt (11) form a type of perforated sieve into which finer sieve material falls and is transported further in the longitudinal direction of the sieve conveyor belt (16). Only through the deflection process via the deflection roller (13) does the fine material (28) drop out as a separate sorting fraction. In contrast, the material that is too large for the sieve pockets (14) is transported further in the transverse direction of the sieve conveyor belt (17) and discharged as coarse material (29) in the discharge device (22). In order to ensure a sufficient residence time of the material mixture on the sieve conveyor belt (11), this must have a certain minimum width (B), which corresponds to the length of a drum sieve device including the supporting structure. The width (B) is of the order of B∼4 m.

Die auf dem Siebförderband angeordneten Siebtaschen (14) können in ihrer Taschengröße entweder alle gleich groß oder auch unterschiedlich groß ausgestaltet sein. So wäre es möglich, im Bereich der Aufgabevorrichtung (19) gröbere Taschen und im Bereich der Austragevorrichtung (22) feinere Siebtaschen anzuordnen, um den während des Siebvorganges sich ständig auflösenden und trennenden Wertstoffgemisches Rechnung zu tragen. Es könnten dann im Bereich der Umlenkrolle (13) unterschiedlich große Fraktionen als Grobfraktion (28a) und Feinfraktion (28b) entnommen werden. Die Siebtaschen (14) können auch als Längsrinnen ausgebildet sein, mit einer Längserstreckung in Richtung der Siebförderbandquerrichtung (17). In diese Rinnen können beispielsweise längliche Güter wie Stangen, Bretter usw. aufgenommen werden. In Fig. 1 ist weiterhin eine Prallwand (50) mit flexiblem Vorhang (51) z. B. aus einem Kettenvorhang o. dgl. dargestellt. Diese Prallwand hält durch den Trommeleffekt zurückgeworfenes Material zurück.The sieve pockets (14) arranged on the sieve conveyor belt can either be all the same size or different in their pocket size. It would thus be possible to arrange coarser pockets in the area of the feed device (19) and finer sieve pockets in the area of the discharge device (22) in order to take into account the mixture of valuable substances which is constantly dissolving and separating during the sieving process. Fractions of different sizes could then be removed as coarse fraction (28a) and fine fraction (28b) in the area of the deflection roller (13). The sieve pockets (14) can also be designed as longitudinal channels, with a longitudinal extension in the direction of the sieve conveyor belt transverse direction (17). For example, elongated goods such as poles, boards, etc. can be accommodated in these channels. In Fig. 1 is also a baffle (50) with a flexible curtain (51) z. B. from a chain curtain or the like. This baffle holds back material thrown back by the drum effect.

Der in Fig. 2a dargestellte Längsschnitt durch die Siebförderbandlängsrichtung zeigt deutlich den Aufbau und die Wirkung des Siebförderbands (11) nach Art eines Trommelsiebs. Die Zylindermantelfläche (23) erstreckt sich nahezu um einen vollen Halbkreis mit dem Radius (r). Die Transportrichtung des Siebförderbands (11) in Siebförderbandlängsrichtung ist mit Pfeil (30) gekennzeichnet. Pfeil (31) zeigt den Umwälzvorgang des Wertstoffgemisches (32), hervorgerufen durch den Trommelsiebeffekt. Das Feingut (28) wird in den Siebtaschen (14) gesammelt und in Richtung Pfeil (33) zur oberen Umlenkrolle (13) transportiert und umgelenkt. Im Bereich des Transportpfeils (34) kippt das Feingut (28) aus den sich umdrehenden und öffnenden Siebtaschen (14) heraus.The longitudinal section shown in FIG. 2a through the longitudinal direction of the sieve conveyor belt clearly shows the structure and the effect of the sieve conveyor belt (11) in the manner of a drum sieve. The cylindrical surface (23) extends almost around a full semicircle with the radius (r). The transport direction of the sieve conveyor belt (11) in the longitudinal direction of the sieve conveyor belt is indicated by arrow (30). Arrow (31) shows the circulation process of the material mixture (32), caused by the drum screen effect. The fine material (28) is collected in the sieve pockets (14) and transported and deflected in the direction of arrow (33) to the upper deflection roller (13). In the area of the transport arrow (34), the fine material (28) tilts out of the rotating and opening sieve pockets (14).

Die Längsachse (25) der oberen Umlenkrolle (13) befindet sich in einer Höhe (H₁∼2,1 bis 2,4 m) oberhalb der Längsachse (24) der Umlenkrolle (12). Diese Höhe (H₁) bestimmt im Zusammenhang mit der seitlichen Länge (L₁∼­5,1 m) den Krümmungsradius (r) des trommelsiebartigen Siebförderbands (11). Im Ausführungsbeispiel nach Fig. 2a befindet sich der tiefste Punkt (26) des Siebförderbands etwa in gleicher Höhe wie die Längsachse (24) der Umlenkrolle (12). Die in Fig. 1 dargestellte Gesamtlänge (L₂) beträgt ca. L₂∼7,2 m, die Gesamthöhe (H₂) der Siebfördereinrichtung ohne Traggestell (15) ca. H₂∼­5,2 m.The longitudinal axis (25) of the upper guide roller (13) is at a height (H₁∼2.1 to 2.4 m) above the longitudinal axis (24) of the guide roller (12). This height (H₁) determines the radius of curvature (r) of the drum-like sieve conveyor belt (11) in connection with the lateral length (L₁∼5.1 m). In the exemplary embodiment according to FIG. 2a, the lowest point (26) of the sieve conveyor belt is approximately at the same height as the longitudinal axis (24) of the deflection roller (12). The total length shown in Fig. 1 (L₂) is approximately L₂∼7.2 m, the total height (H₂) of the screen conveyor without support frame (15) is approximately H₂∼5.2 m.

In Fig. 2b ist die Ansicht "X" nach Fig. 2a dargestellt. Danach wird das Wertstoffgemisch (32) dem Siebförderband (11) an der seitlichen oberen Kante (18) aufgegeben (Pfeil 35) (s. auch Fig. 1). Das Wertstoffgemisch wandert dann durch die Neigung des Siebförderbands (11) und durch den Weitertransport in der trommelartigen Vorrichtung in Richtung der Siebförderbandquerrichtung (17), wobei das Grobgut (29) an der der Seitenkante (18) gegenüberliegenden Kante (21) ausgetragen wird, (Pfeil 29, 36) während das Feingut durch die Siebtaschen (14) in Siebförderbandlängsrichtung (16) gefördert wird. Die in Fig. 2a dargestellten (Pfeile 30, 33) sind in Siebförderbandlängsrichtung (16) ausgerichtet. Die untere (12) und die obere (13) Umlenkrolle ist in Fig. 2b schematisch dargestellt. Die strichpunktierte Linie (37) in Fig. 2b entspricht derjenigen in Fig. 2a und stellt den Außenradius der über die Umlenkrollen (12, 13) laufenden Siebtaschen dar.2b shows the view “X” according to FIG. 2a. The material mixture (32) is then fed to the screen conveyor belt (11) at the lateral upper edge (18) (arrow 35) (see also FIG. 1). The material mixture then migrates in through the inclination of the screen conveyor belt (11) and through further transport in the drum-like device Direction of the cross conveyor belt direction (17), the coarse material (29) being discharged on the edge (21) opposite the side edge (18) (arrow 29, 36) while the fine material is conveyed through the screen pockets (14) in the longitudinal conveyor belt direction (16) . 2a (arrows 30, 33) are aligned in the longitudinal direction of the conveyor belt (16). The lower (12) and the upper (13) deflection roller is shown schematically in Fig. 2b. The dash-dotted line (37) in FIG. 2b corresponds to that in FIG. 2a and represents the outer radius of the sieve pockets running over the deflection rollers (12, 13).

Das Ausführungsbeispiel gemäß Fig. 3 zeigt eine Variante der Ausführungsform nach Fig. 2a. Durch eine geänderte Anordnung oder Form der unteren Umlenkrolle (12) wird ein zunächst ebenes Siebförderband im Bereich des (Pfeils 38) eingerichtet. Dies kann ggf. den Vorteil haben, daß über ein längere Auflagebreite die Wertstoffgemischaufgabe und entsprechende Verteilung auf dem Transportband erfolgen kann.The embodiment according to FIG. 3 shows a variant of the embodiment according to FIG. 2a. Due to a changed arrangement or shape of the lower deflection roller (12), an initially flat screen conveyor belt is set up in the area of (arrow 38). This may have the advantage that the mixture of recyclable materials and corresponding distribution on the conveyor belt can take place over a longer support width.

Prinzipiell arbeitet dieses Siebförderband jedoch gleich wie in Fig. 1 bzw. 2a dargestellt. Gleiche Positionen sind mit gleichen Bezugszeichen dargestellt.In principle, however, this screen conveyor belt works the same as shown in Fig. 1 or 2a. The same positions are shown with the same reference numerals.

In den Figuren 4a und b ist der Aufbau der Siebtaschen (14) sowie die Anordnung in verschiedenen Betriebszuständen dargestellt. Jede Siebtasche (14) besteht aus zwei Seitenwänden (39, 40) in Siebförderbandlängsrichtung (16) sowie zwei Querwänden (41, 42) in Siebförderbandquerrichtung (17). Die Längswände (39, 40) bilden mit der Querwand (41) einen an drei Seiten geschlossenen Behälter, während die vierte Seitenwand (42) jeweils durch die Rückwand (41) der nächstfolgenden Siebtasche gebildet wird. In Fig. 4a ist deshalb die Siebtasche (14) beispielsweise durch die fest miteinander verbundenen Wände (39 bis 41) gebildet, während die Querwand (42) durch die darauffolgende Siebtasche (14ʹ) gebildet wird.4a and b show the structure of the sieve pockets (14) and the arrangement in various operating states. Each sieve pocket (14) consists of two side walls (39, 40) in the longitudinal direction of the conveyor belt (16) and two transverse walls (41, 42) in the transverse direction of the conveyor belt (17). The longitudinal walls (39, 40) form with the transverse wall (41) a container closed on three sides, while the fourth side wall (42) each through the rear wall (41) next sieve pocket is formed. 4a, the sieve pocket (14) is therefore formed, for example, by the walls (39 to 41) which are firmly connected to one another, while the transverse wall (42) is formed by the sieve pocket (14ʹ) which follows.

Wie in Fig. 4a dargestellt, liegt die gegenüber der Siebtasche (14) bewegliche Querwand (42) eng an den Seitenwänden (39, 40) an und bildet einen geschlossenen Behälter. Dieser Zustand ist im Bereich der trommelartigen Ausbildung mit einem Krümmungsradius (r) gegeben. Der schematisch dargestellte Kettenförderer (43) ist in Fig. 4a deshalb in der Formgebung des Trommelsiebs gekrümmt ausgebildet.As shown in Fig. 4a, the transverse wall (42) which is movable with respect to the sieve pocket (14) lies closely against the side walls (39, 40) and forms a closed container. This condition exists in the area of the drum-like design with a radius of curvature (r). The chain conveyor (43) shown schematically in FIG. 4a is therefore curved in the shape of the drum screen.

Im Bereich der Umlenkrollen (11, 12) wird der Kettenförderer (43) in umgekehrter Richtung als im Trommelsiebbereich umgelenkt, so daß die Siebtaschen (14) sich durch Wegschwenken der Querwand (42) öffnen. Das Siebtaschenvolumen wird damit im Umlenkbereich der Umlenkrolle (13) vergrößert, so daß der Inhalt noch leichter herausfallen kann.In the area of the deflection rollers (11, 12), the chain conveyor (43) is deflected in the opposite direction than in the drum sieve area, so that the sieve pockets (14) open when the transverse wall (42) is pivoted away. The sieve pocket volume is thus increased in the deflection area of the deflection roller (13), so that the contents can fall out even more easily.

Damit zwischen der wegklappenden Querwand (42) und dem aus den Wänden (39 bis 41) bestehenden Behälter (14) kein Feingut herausfallen kann, sind die Querwände (41, 42) in ihrem unterhalb des Bodens (44) angeordneten Bereich als U-förmige Auffangvorrichtung (45) ausgebildet. Vom Siebtaschenboden (44) herabrutschende Teile (Pfeil 46) werden deshalb in der U-förmigen Ausnehmung (45) aufgefangen und können nicht zur Verklemmung des Kettenförderers (43) führen.So that no fine material can fall out between the folding transverse wall (42) and the container (14) consisting of the walls (39 to 41), the transverse walls (41, 42) are U-shaped in their area below the floor (44) Collection device (45) formed. Parts that slide down from the bottom of the sieve pocket (44) are therefore caught in the U-shaped recess (45) and cannot lead to the chain conveyor (43) becoming jammed.

Die Seitenwände (39, 40) bzw. Querwände (41, 42) können in ihrem oberen Bereich noch zusätzliche Winkelbleche (47) aufweisen, zur Versteifung der Siebtasche und zur Vermeidung des Herausrutschens von Teilen.The side walls (39, 40) or transverse walls (41, 42) can have additional angle plates (47) in their upper area. have, to stiffen the sieve pocket and to prevent slipping out of parts.

In Fig. 5a und b ist eine alternative Ausführungsform der Siebtasche nach Fig. 4a bzw. 4b dargestellt. Anstelle der U-förmigen Auffangvorrichtung (45) ist ein flexibles Verbindungsband (48) zwischen dem Siebtaschenboden (44) und dem unteren Teil der wegklappbaren Querwand (42) angebracht. Im Bereich der trommelförmigen Ausgestaltung bzw. ebenen Ausgestaltung des Siebförderbands (11) liegt die bewegliche Querwand (42) an den Seitenwänden (39, 40) an. Erst wenn sich der Kettenförderer (43) um die Umlenkrollen (12, 13) bewegt, öffnet sich die Siebtasche (14) und die Querwand (42), welches die Rückwand zur nächstfolgenden Siebtasche darstellt, schwenkt von der Siebtasche weg. Die hierdurch entstehende Öffnung (49) wird durch das flexible Verbindungsband (48) geschlossen.5a and b show an alternative embodiment of the sieve bag according to FIGS. 4a and 4b. Instead of the U-shaped collecting device (45), a flexible connecting band (48) is attached between the sieve pocket bottom (44) and the lower part of the foldable transverse wall (42). The movable transverse wall (42) bears against the side walls (39, 40) in the area of the drum-shaped design or flat design of the screen conveyor belt (11). Only when the chain conveyor (43) moves around the deflection rollers (12, 13) does the sieve pocket (14) open and the transverse wall (42), which represents the rear wall to the next sieve pocket, pivots away from the sieve pocket. The opening (49) thus created is closed by the flexible connecting band (48).

Zur Bildung von größeren Siebtaschen (14) können mehrere Seitenwände (39, 40) entfallen, so daß eine Art Querrinne mit einer Erstreckung in Siebförderbandquerrichtung (17) entsteht.To form larger sieve pockets (14), several side walls (39, 40) can be omitted, so that a kind of transverse trough with an extension in the transverse direction of the sieve belt (17) is created.

Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt. Sie umfaßt vielmehr sämtliche fachmännischen Ausbildungen und Weiterbildungen ohne erfinderischen Gehalt.The invention is not restricted to the exemplary embodiments shown and described. Rather, it encompasses all professional training and further education without inventive step.
