Abstract

Bei einem Verfahren zum Abscheiden von Abfall aus einem Faser-Abfall-Gemisch an einer Textilmaschine wird das Faser-Abfall-Gemisch tangential von einer rotierenden Walze (1) abgeschleudert. Zwecks Schaffung eines Verfahrens, bei dem Abfall mit möglichst wenig Fasern abgeschieden wird, wirkt auf das Faser-Abfall-Gemisch derart ein Luftstrom (6, 7) ein, dass eine Trennung der Fasern von dem Abfall erfolgt, wobei die Fasern wieder auf die Walze zurückgeführt werden und der Abfall abgesaugt wird.In a method for separating waste from a fiber-waste mixture on a textile machine, the fiber-waste mixture is thrown off tangentially by a rotating roller (1). In order to create a process in which waste is deposited with as few fibers as possible, an air flow (6, 7) acts on the fiber-waste mixture in such a way that the fibers are separated from the waste, the fibers again on the roller be returned and the waste is suctioned off.

Description

Die Erfindung betrifft ein Verfahren zum Abscheiden aus einem Faser-Abfall-Gemisch an einer Textilmaschine, bei dem das Faser-Abfall-Gemisch tangential von einer rotierenden Walze abgeschleudert wird und umfaßt eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for separating from a fiber-waste mixture on a textile machine, in which the fiber-waste mixture is thrown off tangentially by a rotating roller and comprises an apparatus for carrying out the method.

Im Bereich der Spinnereivorbereitung, insbesondere beim öffnen, Reinigen und Kardieren, sowie bei nachfolgenden Weiterverarbeitungsschritten müssen Abfälle o. dgl. von Fasern getrennt und abgeschieden werden. Das geschieht regelmäßig in der Praxis über rotierende Walzen in Verbindung mit Rosten u. dgl. Häufig wird mit den Abfällen zugleich ein erheblicher Teil an Fasern abgeschieden. Das ist u. a. auf unkontrollierte Luftströmungen zurückzuführen. Die Ansammlung von Fasern im Abfall stellt einen Verlust dar.In the area of spinning preparation, in particular when opening, cleaning and carding, and in subsequent processing steps, waste or the like must be separated and separated from fibers. This happens regularly in practice on rotating rollers in connection with rusting and. The like. A considerable part of the fibers is often separated with the waste. That is u. a. attributable to uncontrolled air flows. The accumulation of fibers in the waste represents a loss.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, bei dem Abfall mit möglichst wenig Fasern abgeschieden wird, so daß der Verlust an Fasern weitgehend reduziert ist.The invention is therefore based on the object of providing a method of the type mentioned at the beginning, in which Waste is deposited with as few fibers as possible, so that the loss of fibers is largely reduced.

Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved by the characterizing features of claim 1.

Der Erfindung liegt der Gedanke zugrunde, die unterschiedliche Masse der Abfallpartikel und der Fasern zur Trennung der beiden Komponenten heranzuziehen. Dadurch, daß auf das Faser-Abfall-Gemisch ein Luftstrom einwirkt, werden die erheblich leichteren Fasern aus diesem Gemisch herausgeblasen und vorzugsweise auf die rotierende Walze zurückgeführt; der Abfall, der noch wenige Fasern enthalten kann, wird anschließend abgesaugt. Aufgrund der größeren Masse weisen die Abfallteile eine höhere kinetische Energie auf, so daß die Abfallteile in einen z. B. gegenläufigen Fluidstrom einen wesentlich längeren Bremsweg aufweisen, als die Fasern, die eine geringere Masse besitzen. Das erfindungsgemäße Verfahren macht sich diesen Vorgang zunutze und erlaubt dadurch eine sichere Trennung zwischen den Abfallteilen und den Fasern.The invention is based on the idea of using the different mass of the waste particles and the fibers to separate the two components. Due to the fact that an air stream acts on the fiber-waste mixture, the considerably lighter fibers are blown out of this mixture and preferably returned to the rotating roller; the waste, which may still contain a few fibers, is then suctioned off. Due to the larger mass, the waste parts have a higher kinetic energy, so that the waste parts in a z. B. counter-rotating fluid flow have a much longer braking distance than the fibers, which have a lower mass. The method according to the invention takes advantage of this process and thereby allows a safe separation between the waste parts and the fibers.

Das erfindungsgemäße Verfahren wird insbesondere bei rotierenden, garnierten Walzen, z. B. Reinigungswalzen mit Schlagnasen, Vorreißer, Trommel o. dgl. angewandt, die die Abfallteile und Fasern in Rotationsrichtung mitreißen. Dies wird durch äußere Abdeckungen der Walzen möglich. Bei einer oder mehreren Öffnungen in der Abdekkung sind die Abfallteile und die Fasern bestrebt, unter einem bestimmten Winkel tangential an der öffnungsstelle aus der Öffnung herauszutreten.The method according to the invention is used in particular with rotating, garnished rollers, e.g. B. cleaning rollers with impact lugs, licker, drum or the like. Applied to carry the waste parts and fibers in the direction of rotation. This is made possible by the outer covers of the rollers. In the case of one or more openings in the cover, the waste parts and the fibers endeavor to emerge tangentially from the opening at a certain angle at the opening point.

Nach dem Passieren der Öffnung, d. h. beim Wiedereintritt der Garnitur unter die Abdeckung, entsteht am Eintrittsspalt ein Unterdruck, der als Sog (Luftmengendefizit) in Erscheinung tritt. Dieser Sog wird durch den für die Bremswirkung erforderlichen Luftstrom ausgeglichen.After passing through the opening, i.e. H. When the clothing re-enters under the cover, a negative pressure is created at the entry gap, which appears as suction (air deficit). This suction is compensated for by the air flow required for the braking effect.

Bei bekannten Abfallteil- und Faserabmessungen (Größe, Form) können für bestimmte Geschwindigkeiten die Bremswege xkrit p (Bremsweg Abfallteil) und xkrit f (Bremsweg Faser) nach der folgenden Beziehung berechnet werden:

 With known waste part and fiber dimensions (size, shape), the braking distances x crit p (braking distance waste part) and x crit f (braking distance fiber) can be calculated for certain speeds according to the following relationship:

Figure imgb0010

Bei üblicher Geometrie der Abfallteile und Fasern läßt sich errechnen, daß die Bremswege der Abfallteile und der Fasern sich etwa wie folgt verhalten:

Figure imgb0011
With the usual geometry of the waste parts and fibers, it can be calculated that the braking distances of the waste parts and fibers behave approximately as follows:
Figure imgb0011

Das bedeutet, daß ein Abfallteil im gegenläufigen Luftstrom ca. 10 bis 20 mal so weit wie eine Faser fliegen kann, so daß auf diese Weise eine wirkungsvolle Trennungder Abfallteile von den Fasern verwirklicht werden kann.This means that a waste part in the opposite air flow can fly about 10 to 20 times as far as a fiber, so that an effective separation of the waste parts from the fibers can be achieved.

Zweckmäßig wird der Luftstrom in entgegengesetzter Richtung auf das Faser-Abfall-Gemisch gerichtet. Vorzugsweise wird der Luftstrom schräg oder etwa senkrecht auf das Faser-Abfall-Gemisch, und zwar in Richtung auf die Walze gerichtet, so daß die Fasern wieder auf die Walze zurückgeführt werden können.The air flow is expediently directed in the opposite direction onto the fiber / waste mixture. The air stream is preferably directed obliquely or approximately perpendicularly to the fiber-waste mixture, specifically in the direction of the roller, so that the fibers can be returned to the roller.

Eine vorteilhafte Vorrichtung zur Durchführung des Verfahrens ist dadurch gekennzeichnet, daß in Richtung der Fliehkraft des Faser-Abfall-Gemisches ein Bremskanal vorgesehen ist, der in eine Abfallsammelkammer führt, die an eine Absaugeinrichtung angeschlossen ist und daß ein an eine Druckluftquelle angeschlossener Druckluftkanal vorgesehen ist, dessen Ausgang auf den Bremskanal gerichtet ist.An advantageous device for carrying out the method is characterized in that a braking duct is provided in the direction of the centrifugal force of the fiber-waste mixture, which leads into a waste collecting chamber which is connected to a suction device and that a compressed air duct connected to a compressed air source is provided, whose output is directed to the brake channel.

Vorzugsweise ist die Weite des Bremskanals einstellbar, um eine Dosierung für die Abstimmung des Bremsluftstromes zu ermöglichen. Zweckmäßig ist eine Arretierung dieser Einstellung vorgesehen.The width of the brake duct is preferably adjustable in order to enable metering for the adjustment of the brake air flow. This setting is expediently locked.

Bevorzugt ist die Länge des Bremskanals einstellbar. Dadurch kann der Bremsweg variiert werden, so daß am Ort die noch zur Abscheidung zuzulassenden Grenzpartikelgrößen eingestellt werden können. Nach einer weiteren vorteilhaften Ausführungsform ist die Richtung des Druckluftkanals einstellbar.The length of the brake channel is preferably adjustable. This allows the braking distance to be varied so that the limit particle sizes still to be permitted for separation can be set on site. According to a further advantageous embodiment, the direction of the compressed air channel is adjustable.

Figur 1 zeigt die Trommel 1 einer nicht näher dargestell- .ten Karde. Die Trommel 1 dreht sich entgegen dem Uhrzeigersinn (sh. Pfeil). Der Trommel 1 ist ein Trommelabdeckblech 2 zugeordnet, das eine Öffnung 3 aufweist. Das Faser-Abfall-Gemisch wird von der Trommel mitgerissen und tritt an der öffnung 3 in Richtung der Fliehkraft in einen Bremskanal 4. Der Bremskanal 4 führt in eine Abfallsammelkammer 5, die an eine (nicht dargestellte) Absaugeinrichtung angeschlossen ist. In der Verlängerung des Bremskanals 4 und etwas abgesetzt vom unteren Trommelabdeckblech 2 ist ein Druckluftkanal 6 vorgesehen, der über einen Druckluftanschluß 7 an eine Druckluftkammer 8 angeschlossen ist, die mit einer (nicht dargestellten) Druckluftquelle in Verbindung steht. Der Ausgang des Druckluftkanals 6 ist auf den Eingang des Bremskanals 4 gerichtet. Am Ausgang des Bremskanals 4 ist ein Verstellelement 9 vorgesehen, mit dem die Weite des Bremskanals 4 einstellbar ist. Dieses Verstellelement 9 kann arretiert werden.Figure 1 shows the drum 1 of a card, not shown. The drum 1 rotates counterclockwise (see arrow). The drum 1 is assigned a drum cover plate 2 which has an opening 3. The fiber-waste mixture is entrained by the drum and enters the brake channel 4 at the opening 3 in the direction of the centrifugal force. The brake channel 4 leads into a waste collection chamber 5 which is connected to a suction device (not shown). In the extension of the brake channel 4 and somewhat offset from the lower drum cover plate 2, a compressed air channel 6 is provided which is connected via a compressed air connection 7 to a compressed air chamber 8 which is connected to a compressed air source (not shown). The outlet of the compressed air duct 6 is directed towards the inlet of the brake duct 4. At the output of the brake channel 4, an adjusting element 9 is provided, with which the width of the brake channel 4 can be adjusted. This adjustment element 9 can be locked.

Im Betrieb wird das Faser-Abfall-Gemisch durch die Trommel 1 mitgerissen und tritt durch die Öffnung 3 im Trommelabdeckblech 2 heraus und in den Bremskanal 4 ein. Ein Luftstrom aus dem Bremskanal 6 wirkt schräg auf das Faser-Abfall-Gemisch ein und bläst dabei die Fasern auf die Trommel zurück. Die Abfallteile fliegen infolge ihrer größeren Massen weiter in den Bremskanal 4 und werden über die Abfallsammelkammer und die Absaugeinrichtung entfernt.In operation, the fiber-waste mixture is entrained by the drum 1 and exits through the opening 3 in the drum cover plate 2 and into the brake channel 4. An air flow from the brake channel 6 acts obliquely on the fiber-waste mixture and blows the fibers back onto the drum. The waste parts fly due to their larger masses into the brake channel 4 and are removed via the waste collection chamber and the suction device.

Nach Figur 2 ist die Länge des Bremskanals 4 einstellbar. Dazu ist der Bremskanal 4 als Stutzen 41 ausgebildet, über dessen Ende ein Rohrstutzen 42 gestülpt ist. Das Ende des Rohrstutzens 42 ist auf dem Ende 41 verschiebbar angeordnet und z. B. durch eine Arretiereinrichtung 10 feststellbar. Weiterhin ist die Richtung des Druckluftkanals 6 einstellbar. Der Druckluftkanal 6 besteht aus der Wand 61, der eine bewegliche Wand 62 gegenüberliegt. Diese Wand 62 kann je nach Partikelaustrittswinkeln und- Geschwindigkeit variiert werden.According to Figure 2, the length of the brake channel 4 is adjustable. For this purpose, the brake channel 4 is designed as a socket 41, over the end of which a pipe socket 42 is slipped. The end of the pipe socket 42 is slidably arranged on the end 41 and z. B. detectable by a locking device 10. Furthermore, the direction of the compressed air channel 6 is adjustable. The compressed air duct 6 consists of the wall 61, which is opposite a movable wall 62. This wall 62 can be varied depending on the particle exit angle and speed.
