Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Reinigung von Fasergut mit einem eine Reinigungswalze und ein Reinigergehäuse aufweisenden Reiniger und einem oberhalb des Reinigers angeordneten Kondenser.The invention relates to a device for the purification of fiber material with a cleaning roller and a cleaner housing having cleaner and arranged above the cleaner Kondenser.

Aus dem Stand der Technik, z. B. aus der veröffentlichten CH 695 154 A5 , sind Vorrichtungen bekannt, welche zum Öffnen und Reinigen von Fasergut vorgesehen sind. Dabei wird das Fasergut (z. B. in Form von Faserflocken) über einen Transportkanal unter Einwirkung einer erzeugten Transportluft einem Kondenser zugeführt, welcher mit einer drehbar gelagerten Siebtrommel versehen ist. Innerhalb der Siebtrommel ist ein Unterdruck angelegt, der von einer Unterdruckquelle erzeugt wird. Dadurch wird das, der Siebtrommel zugeführte Fasergut auf die Oberfläche der Siebtrommel angesaugt und auf dieser abgelegt. Bei diesem Vorgang erfolgt eine Trennung zwischen dem Fasergut und der Transportluft. Die nunmehr sich auf der Oberfläche (Aussenumfang) der Siebtrommel gebildete Fasermatte wird durch die Drehbewegung der Siebtrommel zu einer rotierenden Speisewalze (Fächerwalze) überführt, welche mit nach aussen ragenden Abstreifern, bzw. mit Fächern versehen ist, über welche das auf der Siebtrommel befindliche Fasergut abgenommen wird. Das abgenommene Fasergut wird durch die Drehbewegung der Speisewalze an einen nachfolgenden Kanal abgegeben, welcher die Form eines Trichters aufweist und in eine Einlauf, bzw. Eintrittsstutzen eines nachfolgenden Reinigers mündet. Der Reiniger ist mit einer Reinigungswalze versehen, über welche das Fasergut spiralförmig in Richtung der Längsachse der Reinigungswalze bis zu einer Abgabeöffnung transportiert wird. Der spiralförmige Transport des Fasergutes wird durch entsprechend im Reiniger angebrachte Leitelemente bewirkt. Während des Transportes des Fasergutes durch den Reiniger passiert dieses mehrmals einen unterhalb der Reinigungswalze angebrachten Rost, über welchen durch den Einfluss von, auf der Reinigungswalze angebrachten Schlagstiften und unter Einwirkung der Fliehkraft Verunreinigungen aus dem Fasergut abgeschieden werden.From the prior art, for. B. from the published CH 695 154 A5 , Devices are known which are provided for opening and cleaning of fiber material. In this case, the fiber material (eg in the form of fiber flakes) is fed via a transport channel under the action of a generated transport air to a condenser, which is provided with a rotatably mounted screen drum. Within the screen drum, a negative pressure is applied, which is generated by a vacuum source. As a result, the fiber material supplied to the screen drum is sucked onto the surface of the screen drum and deposited thereon. In this process, there is a separation between the fiber and the transport air. The now formed on the surface (outer circumference) of the screen drum fiber mat is transferred by the rotational movement of the screen drum to a rotating feed roller (fan roller), which is provided with outwardly projecting scrapers, or with subjects, on which the fiber drum located on the screen drum is removed. The removed fiber material is delivered by the rotational movement of the feed roller to a subsequent channel, which has the shape of a funnel and opens into an inlet, or inlet connection of a subsequent cleaner. The cleaner is provided with a cleaning roller, via which the fiber material is transported spirally in the direction of the longitudinal axis of the cleaning roller to a discharge opening. The spiral transport of the fiber material is effected by appropriately mounted in the cleaner guide elements. During the transport of the fiber material through the cleaner this happens several times below the cleaning roller mounted grate, over which by the influence of, mounted on the cleaning roller pins and under the action of centrifugal impurities from the fiber material are deposited.

Durch den Einsatz eines trichterförmigen Kanals zwischen der Speisewalze und eines Eintrittsstutzens des nachfolgenden Reinigers wird das, von einer Siebtrommel über eine grosse Querschnittsfläche abgegebene Fasergut, auf die Querschnittsfläche des Eintrittsstutzens zusammengeführt. Nachteilig an dieser Ausführung ist, dass innerhalb des Kanals Störungen entstehen, durch welche Ablagerungen und Verstopfungen im Kanal auftreten. Diese Störungen können durch Reibungen an den Kanalinnenwänden und unerwünschte Luftströmungen innerhalb des Kanals entstehen. Ebenso kommen bei den bekannten Ausführungen unerwünschte Verdichtungen des Fasergutes im Kanal vor.Through the use of a funnel-shaped channel between the feed roller and an inlet nozzle of the subsequent cleaner is the, from a sieve drum over a large cross-sectional area discharged fiber material, merged into the cross-sectional area of the inlet nozzle. A disadvantage of this design is that within the channel disturbances occur through which deposits and blockages occur in the channel. These disturbances can be caused by friction on the channel inner walls and unwanted air currents within the channel. Likewise, unwanted densifications of the fiber material in the channel occur in the known embodiments.

Der Erfindung liegt nunmehr die Aufgabe zugrunde eine Vorrichtung zur Reinigung von Fasergut vorzuschlagen, welche ein kontinuierliches Reinigen von Fasergut mit hoher Produktivität mit einer störungsfreien Übergabe des Fasergutes vom Kondenser in den Reiniger ermöglicht.The invention is now based on the object to propose a device for the purification of fiber material, which allows a continuous cleaning of fiber material with high productivity with a trouble-free transfer of the fiber material from the condenser in the cleaner.

Die Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des unabhängigen Anspruchs.The object is achieved by a device having the features of the independent claim.

Zur Lösung der Aufgabe wird eine neuartige Vorrichtung zur Reinigung von Fasergut mit einem eine Reinigungswalze und ein Reinigergehäuse aufweisenden Reiniger und einem oberhalb des Reinigers angeordneten Kondenser und einer pneumatischen Zuführung des Fasergutes mit Transportluft zum Kondenser vorgeschlagen. Der Kondenser weist eine luftdurchlässige, in einem Siebtrommelgehäuse drehbar gelagerte Siebtrommel und eine, in einem Speisewalzengehäuse drehbar gelagerte Speisewalze mit jeweils einer Längsachse auf. Die Speisewalze ist zwischen der Siebtrommel und der Reinigungswalze angeordnet und das Fasergut ist mit der Transportluft auf eine äussere Oberfläche der Siebtrommel gerichtet geführt. Es ist eine Trennung von Fasergut und Transportluft durch die Siebtrommel vorgesehen, wobei ein Innenraum der Siebtrommel an eine Unterdruckquelle angeschlossen ist. Die Speisewalze weist an ihrem Umfang in Richtung der Längsachse angeordnete radial abstehende Rippen mit äusseren Enden auf, welche einen Hüllkreis bilden. Zwischen der äusseren Oberfläche der Siebtrommel und dem Hüllkreis der Speisewalze ist ein Abstand von weniger als 1,0 mm vorgesehen. Ein Abstand zwischen dem Hüllkreis der Speisewalze und einer Oberfläche der Reinigungswalze beträgt 30 mm bis 250 mm.To solve the problem, a novel device for cleaning of fiber material with a cleaning roller and a cleaner housing having cleaner and a cleaner arranged above the condenser and a pneumatic feed of the fiber material with transport air to the condenser proposed. The condenser has an air-permeable, in a screen drum housing rotatably mounted screen drum and a rotatably mounted in a Speisewalzengehäuse feed roller, each having a longitudinal axis. The feed roller is arranged between the screen drum and the cleaning roller and the fiber material is guided with the transport air directed onto an outer surface of the screen drum. There is provided a separation of fiber material and transport air through the screen drum, wherein an interior of the screen drum is connected to a vacuum source. The feed roller has on its circumference in the direction of the longitudinal axis arranged radially projecting ribs with outer ends, which form an enveloping circle. Between the outer surface of the screen drum and the enveloping circle of the feed roller is provided a distance of less than 1.0 mm. A distance between the enveloping circle of the feed roller and a surface of the cleaning roller is 30 mm to 250 mm.

Damit wird ermöglicht, dass infolge des vorgeschlagenen geringen Abstandes zwischen der Oberfläche der Siebtrommel und der Rippen der Speisewalze ein vollständiges Abstreifen des Fasergutes gewährleistet wird und zusätzlich eine Sperrwirkung für die Transportluft entsteht, um zu verhindern, dass diese zum nachfolgenden Reiniger gelangt. Gleichzeitig wird durch die unmittelbare Abgabe des Fasergutes von der Speisewalze in eine Eingangsöffnung des nachfolgenden Reinigers ohne Zwischenschaltung eines zusätzlichen Kanals oder Füllschachtes ein störungsfreier Übergang des Fasergutes vom Kondenser in den Reiniger gewährleistet.This makes it possible that as a result of the proposed small distance between the surface of the drum and the ribs of the feed roller complete stripping of the fiber material is ensured and in addition creates a barrier effect on the transport air, to prevent them from getting to the subsequent cleaner. At the same time a trouble-free transition of the fiber material is ensured by the condenser in the cleaner by the immediate delivery of the fiber material from the feed roller in an input port of the subsequent cleaner without the interposition of an additional channel or hopper.

Für die unmittelbare Übernahme des von der Speisewalze nach unten abgegebenen Fasergutes durch die nachfolgende Reinigungswalze des Reinigers ist der Abstand zwischen den äusseren Enden der Rippen der Speisewalze und der Oberfläche der Reinigungswalze auf 30 mm bis 250 mm begrenzt, wobei vorteilhafterweise das Speisewalzengehäuse im Bereich einer Eingangsöffnung des Reinigers mit dem Reinigergehäuse verbunden ist. Damit wird ein gleichmässiger und störungsfreier Fasergutstrom zum Reiniger im Anschluss an die Speisewalze gewährleistet. Der Kondenser ist somit direkt auf dem Reinigergehäuse aufgesetzt, was auch zu einer konstruktiv einfacheren Lösung führt.For the direct takeover of the downwardly discharged from the feed roller fiber material by the subsequent cleaning roller of the cleaner, the distance between the outer ends of the ribs of the feed roller and the surface of the cleaning roller is limited to 30 mm to 250 mm, advantageously the feed roller housing in the region of an inlet opening of the cleaner is connected to the cleaner housing. This ensures a uniform and trouble-free fiber flow to the cleaner following the feed roller. The condenser is thus placed directly on the cleaner housing, which also leads to a structurally simpler solution.

Vorteilhafterweise beträgt eine Drehzahl der Speisewalze 300 bis 500 Umdrehungen pro Minute und der Siebtrommel 100 bis 200 Umdrehungen pro Minute. Damit werden eine schonende Behandlung des Fasergutes und ein sicheres Abstreifen des Fasergutes von der Siebtrommel gewährleistet. Durch den in der Regel grösseren Durchmesser der Siebtrommel gegenüber dem Hüllkreisdurchmesser der Speisewalze ergibt sich eine nahezu gleichgrosse Umfangsgeschwindigkeit zwischen der Oberfläche der Siebtrommel und den äusseren Enden der Rippen der Speisewalze, womit der Abstreifvorgang des Fasergutes von der Siebtrommel gewährleistet wird, wobei vorteilhafterweise der Abstand zwischen dem Hüllkreis der Speisewalze und der äusseren Oberfläche der Siebtrommel Null ist und sich der Hüllkreis der Speisewalze und die äussere Oberfläche der Siebtrommel berühren.Advantageously, a speed of the feed roller is 300 to 500 revolutions per minute and the screen drum 100 to 200 revolutions per minute. This ensures a gentle treatment of the fiber material and a safe stripping of the fiber material from the sieve drum. Due to the generally larger diameter of the screen drum relative to the enveloping circle diameter of the feed roller results in a nearly equal circumferential speed between the surface of the screen drum and the outer ends of the ribs of the feed roller, whereby the stripping process of the fiber material is ensured by the screen drum, advantageously the distance between the enveloping circle of the feed roller and the outer surface of the screen drum is zero and touching the enveloping circle of the feed roller and the outer surface of the screen drum.

Bevorzugterweise sind eine Drehrichtung der Speisewalze und der Siebtrommel entgegengerichtet, wodurch der Abstreifvorgang weiter verbessert wird.
Vorteilhafterweise sind die Achsen der Siebtrommel und der Speisewalze parallel zur Achse der Reinigungswalze angeordnet. Dadurch wird eine kontinuierliche tangentiale Zuführung des Fasergutstromes zur Reinigungswalze gewährleistet.Preferably, a direction of rotation of the feed roller and the screen drum are opposite, whereby the stripping process is further improved.
Advantageously, the axes of the screen drum and the feed roller are arranged parallel to the axis of the cleaning roller. This ensures a continuous tangential feeding of the fiber flow to the cleaning roller.

Um die Breite des von der Siebtrommel abgestreiften Fasergutstromes auf die nachfolgende Eingangsöffnung des Einlaufes des Reinigers anzupassen weist bevorzugterweise die Speisewalze eine Länge auf, welche der Länge der Eingangsöffnung des Reinigers entspricht. Damit sind keine weiteren Mittel notwendig, um den von der Speisewalze abgegebenen Fasergutstrom auf die Breite der Eingangsöffnung des Reinigers anzupassen. Entsprechend ist es von Vorteil, wenn eine Länge der Speisewalze einer Länge der Siebtrommel entspricht.In order to adapt the width of the stripped Fasergutstromes of the screen drum to the subsequent inlet opening of the inlet of the cleaner preferably has the feed roller on a length which corresponds to the length of the inlet opening of the cleaner. Thus, no further means are necessary to adapt the output of the feed roller Fasergutstrom to the width of the inlet opening of the cleaner. Accordingly, it is advantageous if a length of the feed roller corresponds to a length of the screen drum.

Figur 1 zeigt eine schematische Darstellung einer Ausführungsform einer Reinigungsvorrichtung nach dem Stand der Technik, welche einen Kondenser 4 und einen unterhalb des Kondensers 4 angeordneten Reiniger 1 mit einer in einem Reinigergehäuse 22 drehbar gelagerten Reinigungswalze 3 umfasst. Der Kondenser 4 weist eine um eine Längsachse 7 drehbar in einem Siebtrommelgehäuse 14 gelagerte Siebtrommel 5 auf, welche über einen Kanal 17 mit Fasergut 2 beschickt wird, und eine um eine Längsachse 8 drehbar in einem Speisewalzengehäuse 18 gelagerte Speisewalze 6 (auch Fächerwalze genannt) auf. FIG. 1 shows a schematic representation of an embodiment of a cleaning device according to the prior art, which comprises a condenser 4 and arranged below the condenser 4 cleaner 1 with a cleaning housing 3 rotatably mounted in a cleaning roller 3. The condenser 4 has a sieve drum 5 mounted rotatably about a longitudinal axis 7 in a sieve drum housing 14, which is fed with fiber material 2 via a channel 17, and one about a longitudinal axis 8 rotatably mounted in a feed roller housing 18 feed roller 6 (also called fan roller) on.

Mittels Transportluft 9 wird das Fasergut 2 der Siebtrommel 5 zugeführt. Im Innenraum 25 der Siebtrommel 5 ist ein Unterdruck durch eine Unterdruckquelle 29 angelegt. Dadurch wird das zugeführte Fasergut 2 auf die Oberfläche 10 der Siebtrommel 5 angesaugt und durch die luftdurchlässige Oberfläche 10 der Siebtrommel 5 von der Transportluft 9 getrennt, welche die Öffnungen der Siebtrommel 5 passiert und über die Unterdruckquelle 29 abgeführt wird. Bei diesem Vorgang bildet sich ein Fasergutvlies auf dem Umfang 10 der Siebtrommel 5, welches durch die, mit einem Pfeil gekennzeichnete Drehrichtung der Siebtrommel 5 zu einer Durchtrittsöffnung 28 im Siebtrommelgehäuse 14 überführt wird.By means of transport air 9, the fiber material 2 of the screen drum 5 is supplied. In the interior 25 of the screen drum 5, a negative pressure is applied by a vacuum source 29. Thereby, the supplied fiber material 2 is sucked onto the surface 10 of the screen drum 5 and separated by the air-permeable surface 10 of the screen drum 5 of the transport air 9, which passes through the openings of the screen drum 5 and is discharged via the vacuum source 29. In this process, a fibrous nonwoven forms on the circumference 10 of the screen drum 5, which is transferred by the, indicated by an arrow direction of rotation of the screen drum 5 to a passage opening 28 in the screen drum housing 14.

Die Speisewalze 6 ist unterhalb der Siebtrommel 5 angeordnet und das Speisewalzengehäuse 18 schliesst unmittelbar an das Siebtrommelgehäuse 14 an. Die Drehrichtung der Speisewalze 6 entspricht der Drehrichtung der Siebtrommel 5. Dadurch bewegen sich die Oberfläche der Speisewalze 6 und die Oberfläche 10 der Siebtrommel 5 in entgegengesetzter Richtung.The feed roller 6 is arranged below the screen drum 5 and the feed roller housing 18 directly adjoins the screen drum housing 14. The direction of rotation of the feed roller 6 corresponds to the direction of rotation of the screen drum 5. As a result, the surface of the feed roller 6 and the surface 10 of the screen drum 5 move in the opposite direction.

Das auf der Oberfläche 10 der Siebtrommel 5 gebildete Fasergutvlies wird durch die Drehbewegung der Speisewalze 6 und den am Umfang der Speisewalze 6 angebrachten, nach aussen ragenden Rippen 11 abgestreift und über Schwerkraft nach unten in einen Förderkanal 20 abgegeben. Der Förderkanal 20 ist dabei trichterförmig ausgebildet (siehe Fig.2 der CH 695 154 A5 ), damit die von der Speisewalze 6 abgegebene Fasergutmasse auf den Querschnitt einer nachfolgenden Eingangsöffnung 21 des Reinigers 1 zusammengefasst wird. Über diese Eingangsöffnung 21 wird das Fasergut tangential der Reinigungswalze 3 zugeführt. Die Reinigungswalze 3 ist auf ihrem Aussenumfang mit Schlagstiften 23 versehen, über welche das zugeführte Fasergut im Zusammenwirken mit oberhalb der Reinigungswalze 3 angeordneten Leitblechen 27 schraubenlinienförmig in Richtung der Längsachse 12 zu einem Auslauf 26 des Reinigers überführt wird. Nachfolgend wird das gereinigte Fasergut an weitere Prozessstufen abgegeben. Bei diesem schraubenlinienförmigen Transport innerhalb des Reinigers 1 wird das Fasergut mehrmals an einem unterhalb der Reinigungswalze 3 angebrachten Rost 24 vorbeigeführt, dabei werden Verunreinigungen aus dem Fasergut abgeschieden.The formed on the surface 10 of the screen drum 5 Fasergutvlies is stripped by the rotational movement of the feed roller 6 and attached to the circumference of the feed roller 6, outwardly projecting ribs 11 and discharged by gravity down into a conveyor channel 20. The delivery channel 20 is funnel-shaped (see Fig.2 of the CH 695 154 A5 ), so that the output of the feed roller 6 Fasergutmasse is summarized on the cross section of a subsequent input port 21 of the cleaner 1. The fiber material is fed tangentially to the cleaning roller 3 via this inlet opening 21. The cleaning roller 3 is provided on its outer circumference with impact pins 23, via which the supplied fiber material in cooperation with arranged above the cleaning roller 3 baffles 27 is helically transferred in the direction of the longitudinal axis 12 to an outlet 26 of the cleaner. Subsequently, the cleaned fiber material is transferred to further process stages. In this helical transport within the cleaner 1 the fiber material is passed several times at a mounted below the cleaning roller 3 grate 24, while impurities are separated from the fiber material.

Die Siebtrommel 5 ist in einem Siebtrommelgehäuse 14 um eine Längsachse 7 drehbar gelagert. Die Speisewalze 6 ist in einem Speisewalzengehäuse 18 um eine Längsachse 8 drehbar gelagert. Der Kondenser 4 respektive die Siebtrommel 5 wird über einen Kanal 17 mit Fasergut 2 mittels Transportluft 9 beschickt. Die Siebtrommel 5 ist mit ihrem Innenraum 25 mit einer Unterdruckquelle 29 verbunden. Dadurch wird das zugeführte Fasergut 2 auf die Oberfläche 10 der Siebtrommel 5 angesaugt und durch die luftdurchlässige Oberfläche 10 der Siebtrommel 5 von der Transportluft 9 getrennt, welche die Öffnungen der Siebtrommel 5 passiert und über die Unterdruckquelle 29 abgeführt wird. Bei diesem Vorgang bildet sich ein Fasergutvlies auf dem Umfang 10 der Siebtrommel 5, welches durch die, mit einem Pfeil gekennzeichnete Drehrichtung der Siebtrommel 5 zu einer Durchtrittsöffnung 28 im Siebtrommelgehäuse 14 überführt wird.Also in the embodiment of the FIG. 2 is a cleaner 1 with a about a longitudinal axis 12 in a cleaner housing 22 rotatably mounted cleaning roller 3 and a condenser 4 with a sieve drum 5 and a feed roller 6 is provided.

In this process, a fibrous nonwoven forms on the circumference 10 of the screen drum 5, which is transferred by the, indicated by an arrow direction of rotation of the screen drum 5 to a passage opening 28 in the screen drum housing 14.

Das auf dem Umfang 10 der Siebtrommel 5 gebildete Fasergutvlies wird im Bereich der Durchtrittsöffnung 28 von der unterhalb der Siebtrommel 5 angeordneten Speisewalze 6 abgestreift und zur Eingangsöffnung 21 des Reinigers 1 gefördert. Die Enden 15 der auf der Speisewalze 6 am Umfang angebrachten Rippen 11 bilden einen Hüllkreis 13 der Speisewalze. Die Speisewalze 6 ist zur Siebtrommel so angeordnet, dass ein Abstand a zwischen dem Hüllkreis 13 der Speisewalze und der Oberfläche 10 der Siebtrommel 5 besteht. Der Abstand a ist dabei kleiner als 1 mm und im besten Fall Null, wodurch die Enden 15 der Rippen 11 beim Abstreifvorgang direkt in Anlage auf der Oberfläche 10 der Siebtrommel 5 kommen.

Thus, the ribs 11 additionally form during the stripping process a blocking element for the passage of transport air still in this area 9th

Durch die gleichgerichteten Drehrichtungen der Siebtrommel 5 und der Speisewalze 6 bewegt sich die Oberfläche 10 der Siebtrommel 5 entgegen den Rippen 11 der Speisewalze. Dadurch wird eine effiziente Abstreifung des Fasergutes von der Siebtrommel 5 erreicht.Due to the rectified directions of rotation of the screen drum 5 and the feed roller 6, the surface 10 of the screen drum 5 moves against the ribs 11 of the feed roller. As a result, efficient stripping of the fiber material from the screen drum 5 is achieved.

Um eine störungsfreie direkte Abgabe von der Speisewalze 6 an die Reinigungswalze 3 zu gewährleisten ist der Abstand b zwischen den äusseren Enden 15 der Rippen 11 der Speisewalze 6 und der Oberfläche 16 der Reinigungswalze 3 von 30 mm bis 250 mm gewählt. Damit wird ein kontinuierlicher Faserguttransport gewährleistet.In order to ensure a trouble-free direct delivery of the feed roller 6 to the cleaning roller 3, the distance b between the outer ends 15 of the ribs 11 of the feed roller 6 and the surface 16 of the cleaning roller 3 is selected from 30 mm to 250 mm. This ensures a continuous transport of fiber material.

Über die Eingangsöffnung 21 wird das Fasergut tangential der Reinigungswalze 3 zugeführt. Die Reinigungswalze 3 ist auf ihrem Aussenumfang mit Schlagstiften 23 versehen, über welche das zugeführte Fasergut im Zusammenwirken mit oberhalb der Reinigungswalze 3 angeordneten Leitblechen 27 schraubenlinienförmig in Richtung der Längsachse 12 zu einem Auslauf 26 überführt wird. Nachfolgend wird das gereinigte Fasergut an weitere Prozessstufen abgegeben. Bei diesem schraubenlinienförmigen Transport innerhalb des Reinigers 1 wird das Fasergut mehrmals an einem unterhalb der Reinigungswalze 3 angebrachten Rost 24 vorbeigeführt, dabei werden Verunreinigungen aus dem Fasergut abgeschieden.The fiber material is fed tangentially to the cleaning roller 3 via the inlet opening 21. The cleaning roller 3 is provided on its outer circumference with impact pins 23, via which the supplied fiber material in cooperation with arranged above the cleaning roller 3 baffles 27 is helically transferred in the direction of the longitudinal axis 12 to an outlet 26. Subsequently, the cleaned fiber material is transferred to further process stages. In this helical transport within the cleaner 1, the fiber material is passed several times at a mounted below the cleaning roller 3 grate 24, while impurities are separated from the fiber.

Dabei ist das Speisewalzengehäuse 18 im Bereich einer Eingangsöffnung 21 des Reinigers 1 mit dem Reinigergehäuse 22 verbunden. Der Kondenser 4 ist somit direkt auf dem Reinigergehäuse 22 aufgesetzt.The fiber material discharged downwardly from the feed roller 6 is directly and immediately supplied to an inlet opening 21 of the cleaner 1, whereby it is discharged directly onto the circumference of the cleaning roller 3 provided with impact pins 23. In this case, the feed roller housing 18 is connected to the cleaner housing 22 in the region of an inlet opening 21 of the cleaner 1. The condenser 4 is thus placed directly on the cleaner housing 22.

Die Siebtrommel 5 weist eine Länge d und die Speisewalze 6 ein Länge c auf, welche gleich gross sind und etwa der Breite der Eingangsöffnung 21 des Reinigers entsprechen. Damit ist es nicht notwendig, das von der Siebtrommel 5 abgegebene Fasergut zusammenzuführen. D.h. das von der Siebtrommel 5 abgegebene Fasergut kann direkt über die Speisewalze 6 der Eingangsöffnung 21 zugeführt werden.The screen drum 5 has a length d and the feed roller 6 a length c, which are equal in size and approximately equal to the width of the inlet opening 21 of the cleaner.
