Abstract

Fibre tufts are introduced with a first airstream into a collecting shaft (12) and removed therefrom at an exit point (27). On the one hand, the discharged fibre material (16) is formed into tufts of a suitable shape. On the other hand, the air of the first airstream is passed through a bypass (21) and used for forming a second airstream which is used for the continued transportation of the tufts formed. This results in a saving of energy for moving the airstreams. In particular, the amount of transportation air flowing outward is significantly reduced and consequently relatively high costs for cleaning such air are also appreciably reduced. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Behandeln von Faserflocken, bei welchem mittels eines ersten Luftstromes Faserflocken laufend an einer Eintrittsstelle in einen Ablagerungsschacht eingebracht werden und bei welchem eingebrachtes Fasermaterial laufend an einer Austrittsstelle dem Ablagerungsschacht wieder entnommen wird.The present invention relates to a method for treating fiber flakes, in which fiber flakes are continuously introduced at an entry point into a deposition shaft by means of a first air stream, and in which introduced fiber material is continuously removed from the deposition shaft at an exit point.

Durch die deutsche Auslegeschrift Nr. 1 286 436 und durch die schweizerische Patentschrift Nr. 599 362 ist es bereits bekannt, Faserflocken mittels Transportluft einem Ablagerungsschacht zuzuführen und in diesem abzulegen. Dabei ist der Schacht mit einer geschlitzten Seitenwand versehen. Diese ermöglicht es der Transportluft, die ja wegbewegt werden muss, durch die Schlitze zu entweichen.It is already known from German patent specification No. 1 286 436 and from Swiss patent specification No. 599 362 to supply fiber flakes to a deposit shaft by means of transport air and to deposit them there. The shaft is provided with a slotted side wall. This enables the transport air, which has to be moved, to escape through the slots.

In der Spinnereivorbereitung entstehen an verschiedenen Stellen Faseransammlungen, z.B. in der Putzerei, an den Karden, an den Strecken, an den Kämmaschinen usw.During the spinning preparation, fiber accumulations occur at various points, e.g. in the blow room, on the cards, on the lines, on the combing machines, etc.

Dieser sogenannte "Abgang" präsentiert sich u.a. in Faserflocken verschiedener Formen. Damit er wieder verwendet werden kann, muss er in einer geeigneten Flockenform vorliegen. Solche Flocken lassen sich beispielsweise wieder verwerten, indem sie mit frischem Flockenmaterial vermischt werden. Die vorliegende Erfindung dient zum Bilden von Faserflocken solcher geeigneter Flockenform und ist dadurch gekennzeichnet, dass das aus dem Ablagerungsschacht wieder entnommene Fasermaterial erneut zu Flocken aufgelöst wird, dass diese Flocken mittels eines zweiten Luftstromes weiter transportiert werden und dass die durch den ersten Luftstrom bedingte, sich vom Ablagerungsschacht wegbewegende Transportluft zum Bilden des zweiten Luftstromes wieder verwendet wird.This so-called "exit" is presented in Fiber flakes of various shapes. So that it can be used again, it must be in a suitable flake form. Such flakes can be recycled, for example, by mixing them with fresh flake material. The present invention is used to form fiber flakes of such a suitable flake shape and is characterized in that the fiber material removed again from the deposition shaft is again broken down into flakes, that these flakes are transported further by means of a second air stream, and that the flakes caused by the first air stream transport air moving away from the deposit shaft is used again to form the second air stream.

Gemäss den obenerwähnten Veröffentlichungen wird die die Flocken zum Ablagerungsschaft transportierende Luft ins Freie geleitet. Es ist dabei zu beachten, dass solche Transportluft mit Kosten verbunden ist: Es muss die zum Bewegen derselben benötigte Energie aufgewandt werden. Zudem muss die ins Freie gelangende Luft gereinigt werden; dabei ist als Folge der heute bestehenden Vorschriften das Erzielen des vorgeschriebenen Reinheitsgrades kostspielig. Durch die Erfindung sollen die Kosten der die Flocken transportierenden Luftströme relativ klein gehalten werden.According to the publications mentioned above, the air transporting the flakes to the deposit shaft is led outside. It should be noted that such transport air is associated with costs: the energy required to move it must be used. In addition, the outside air must be cleaned; as a result of today's regulations, achieving the prescribed level of purity is costly. The aim of the invention is to keep the costs of the air flows transporting the flakes relatively low.

Falls es vorkommen sollte, dass die vom Ablagerungsschacht wegfliessende Luft noch einige der in den Schacht ausgeschiedenen Fasern mitnehmen sollte, so ist dies bei vorliegender Erfindung ohne Bedeutung. Solche mitgenommenen Fasern gelangen in den zweiten Luftstrom, durch welchen die erneut aufgelösten Faserflocken transportiert werden. Sie sind mengenmässig im Vergleich zu diesen Flocken vollständig unbedeutend und vermengen sich mit diesen.If it should happen that the air flowing away from the deposit shaft should also take away some of the fibers which have been separated out in the shaft, this is of no importance in the present invention. Such entrained fibers enter the second air stream through which the redissolved fiber flakes are transported. In terms of quantity, they are completely insignificant compared to these flakes and mix with them.

Die Erfindung bezieht sich ausserdem auf eine Vorrichtung zum Durchführen des Verfahrens. Diese weist den Ablagerungsschacht auf, welcher ein erstes Abteil für die eingebrachten Faserflocken und ein von diesem durch eine luftdurchlässige Wand getrenntes, zweites Abteil für die aus dem ersten Abteil austretende Luft umfasst, und weist ausserdem eine zum ersten Abteil führende, erste pneumatische Transportleitung zum Transportieren der Faserflocken auf. Die Vorrichtung ist gekennzeichnet durch eine sich an der Austrittsstelle am Ablagerungsschacht befindliche Flockenbildungseinrichtung, durch eine von der Flockenbildungseinrichtung wegführende, zweite pneumatische Transportleitung zum Transportieren von Faserflocken und durch eine vom zweiten Abteil des Ablagerungsschachtes zur zweiten Transportleitung führende Umleitung für die aus dem zweiten Abteil austretende, von der ersten Transportleitung gelieferte Transportluft.The invention also relates to a device for performing the method. This has the deposit shaft, which comprises a first compartment for the fiber flakes introduced and a second compartment for the air emerging from the first compartment, separated by an air-permeable wall, and also has a first pneumatic transport line leading to the first compartment for transport of the fiber flakes. The device is characterized by a flocculation device located at the exit point on the deposit chute, by a second pneumatic transport line leading away from the flocculation device for transporting fiber flocks and by a bypass leading from the second compartment of the deposit chute to the second transport line for the exiting from the second compartment. Transport air supplied by the first transport line.

Im folgenden sei die Erfindung anhand eines Ausführungsbeispiels und der Figur näher erläutert. Die letztere ist ein schematischer Querschnitt durch eine erfindungsgemässe Vorrichtung.In the following, the invention will be explained in more detail using an exemplary embodiment and the figure. The latter is a schematic cross section through a device according to the invention.

Die Figur zeigt eine erste, pneumatische Transportleitung 11, welche zum Transport von Faserflocken dient. Anschliessend an diese ist ein Ablagerungsschacht 12 vorgesehen. Dieser besteht aus einem ersten Abteil 13 und einem von diesem durch eine luftdurchlässige Wand 14 getrennten, zweiten Abteil 15. Im ersten Abteil 13 befindet sich in dieses eingebrachtes Fasermaterial 16.The figure shows a first, pneumatic transport line 11, which is used to transport fiber flakes. Following this, a deposit shaft 12 is provided. This consists of a first compartment 13 and one of these through an air-permeable wall 14 separate, second compartment 15. The first compartment 13 contains fiber material 16 introduced therein.

Unterhalb des Schachtes 12 ist eine Flockenbildungseinrichtung vorhanden. Sie besteht aus einer Speisewalze 17, einer neben dieser angeordneten Pressmulde 18 und einer Oeffnungswalze 19. Die letztere ist mit über ihre Mantelfläche verteilten Stiften 20 ausgestattet. Eine zweite pneumatische Transportleitung 22 dient zum Wegführen der durch die Flockenbildungseinrichtung 17, 18, 19 gebildeten Faserflocken.A flocculation device is provided below the shaft 12. It consists of a feed roller 17, a pressing trough 18 arranged next to it and an opening roller 19. The latter is equipped with pins 20 distributed over its outer surface. A second pneumatic transport line 22 serves to lead away the fiber flakes formed by the flaking device 17, 18, 19.

Im Betrieb der Vorrichtung werden durch einen in der Richtung des gezeigten Pfeiles durch die erste Transportleitung 11 fliessenden, ersten Luftstrom Faserflokken an einer Eintrittsstelle 26 in das erste Abteil 13 eingebracht. Dabei strömt die durch den ersten Luftstrom herangebrachte Transportluft durch die luftdurchlässige Wand 14 in das zweite Abteil 15, wie dies wiederum durch Pfeile gezeigt ist. Durch die Rotation der Speisewalze 17 wird das im Schacht 12 bzw. Abteil 13 abgelagerte Flockenmaterial 16 an einer Austrittsstelle 27 erfasst und zwischen der Walze 17 und der Pressmulde 18 durchbewegt. Dadurch bildet sich ein Faserbart 23. Die Stifte 20 der im Gegenuhrzeigersinn rotierenden Oeffnungswalze 19 reissen vom Faserbart 23 Fasern in Form von Faserflocken weg.During operation of the device, fiber flakes are introduced into the first compartment 13 at an entry point 26 by a first air stream flowing through the first transport line 11 in the direction of the arrow shown. The transport air brought in by the first air stream flows through the air-permeable wall 14 into the second compartment 15, as is again shown by arrows. As a result of the rotation of the feed roller 17, the flake material 16 deposited in the shaft 12 or compartment 13 is detected at an exit point 27 and moved through between the roller 17 and the pressing trough 18. This forms a fiber beard 23. The pins 20 of the counterclockwise rotating opening roller 19 tear away from the fiber beard 23 fibers in the form of fiber flakes.

Die ins zweite Abteil 15 eintretende Transportluft wird gemäss der Erfindung nicht ins Freie geleitet, sondern über eine Umleitung 21 der zweiten, pneumatischen Transportleitung 22 zugeführt. Durch diese Luft und durch den in der Leitung 22 fliessenden zweiten Luftstrom werden die mittels der Einrichtung 17, 18, 19 gebildeten Flocken zu ihrer nächsten Verarbeitungsstufe transportiert.According to the invention, the transport air entering the second compartment 15 is not conducted outside, but is supplied to the second pneumatic transport line 22 via a diversion 21. Through this air and through the second air flow flowing in line 22 the flakes formed by means 17, 18, 19 are transported to their next processing stage.

Das Vorsehen der Umleitung 21 vermittelt die eingangs erwähnten Vorteile, nämlich eine nur kleine Verlangsamung der strömenden Transportluft und ein Wegfallen der Notwendigkeit, die die Flocken in den Ablagerungsschacht 12 transportierende Luft reinigen zu müssen.The provision of the diversion 21 conveys the advantages mentioned at the outset, namely only a slight slowdown in the flowing transport air and the elimination of the need to clean the air transporting the flakes into the deposit shaft 12.

Im gezeigten Beispiel weist der Ablagerungsschacht 12 bei einem Schnitt mit einer horizontalen, d.h. zur Zeichenebene senkrechten Ebene, einen rechteckigen Querschnitt auf. Auch das erste Abteil 13 und das zweite Abteil 15 haben einen rechteckigen, horizontalen Querschnitt. Es ist ersichtlich, dass unter diesen Umständen in der gezeigten Ausführungsform, in welcher sich das Abteil 15 und die Umleitung 21 auf der Seite der Pressmulde 18 befinden, die Umleitung 21, welche sich bis zur Leitung 22 erstreckt, nur minimale Umbiegungen aufweist und auch von minimaler Länge ist. Somit übt die Umleitung 21 auf den durch sie fliessenden Luftstrom nur eine kleine Bremswirkung aus. Beim Bilden von Faserflocken rotiert die Oeffnungswalze 19 mit grosser Geschwindigkeit. Damit unterstützt diese Rotation bei der beschriebenen Art der Anordnung zusätzlich die Luftströmung durch die Umleitung 21.In the example shown, the deposit shaft 12 has a horizontal, i.e. plane perpendicular to the drawing plane, a rectangular cross section. The first compartment 13 and the second compartment 15 also have a rectangular, horizontal cross section. It can be seen that under these circumstances, in the embodiment shown, in which the compartment 15 and the bypass 21 are located on the side of the press trough 18, the bypass 21, which extends to the line 22, has only minimal bends and also by minimum length. The diversion 21 thus exerts only a small braking effect on the air flow flowing through it. When forming fiber flakes, the opening roller 19 rotates at high speed. This rotation thus additionally supports the air flow through the diversion 21 in the type of arrangement described.

Gemäss der Figur bildet die Rückseite der Mulde 18 einen Teil der Wand der Umleitung 21, was eine Vereinfachung und Verbilligung der Vorrichtung bedeutet.According to the figure, the back of the trough 18 forms part of the wall of the diversion 21, which means simplifying and reducing the cost of the device.

Es ist unter bestimmten Umständen möglich, dass bei vorgegebenem, erstem Luftstrom der zweite Luftstrom ohne äusseres Dazutun von der gewünschten Stärke ist. Um bei jeder Grösse des ersten Luftstromes den zweiten Luftstrom den Anforderungen entsprechend bemessen zu können, kann in einer speziellen Ausführungsform der Erfindung an der zweiten Transportleitung 22 eine Saugeinrichtung 28 von variabler Saugkraft vorgesehen sein. Falls die von der Leitung 11 bzw. dem zweiten Abteil 15 herkommende Luftmenge für die Leitung 22 zu klein ist, kann in einer weiteren Ausgestaltung der Erfindung die Umleitung 21 mit einer Oeffnung 24 für Falschluft, d.h. für von aussen einströmende Luft, versehen sein. In der Figur ist eine Oeffnung 24 gezeigt, deren Grösse durch einen Schieber 25 eingestellt werden kann.It is possible under certain circumstances that predetermined, first air flow, the second air flow is of the desired strength without external addition. In order to be able to measure the second air flow according to the requirements for each size of the first air flow, a suction device 28 of variable suction power can be provided on the second transport line 22 in a special embodiment of the invention. If the amount of air coming from the line 11 or the second compartment 15 is too small for the line 22, the diversion 21 can be provided with an opening 24 for false air, ie for air flowing in from outside, in a further embodiment of the invention. In the figure, an opening 24 is shown, the size of which can be adjusted by a slide 25.
