Description

Die Erfindung betrifft einen Fasermischer, der zum Einbau in einen freien Raum oder eine Kammer vorgesehen ist, in der das gemischte Fasergut abgelegt wird.The invention relates to a fiber mixer which is provided for installation in a free space or a chamber in which the mixed fiber material is deposited.

Durch die deutsche Patentschrift 330 799 ist ein solcher Fasermischer bekanntgeworden, bei dem die zu mischenden Fasern dem Raum durch einen Luftstrom zugeführt werden und der eine drehbare Verteilereinrichtung aufweist, die von dem die Fasern führenden Luftstrom beaufschlagt wird.Such a fiber mixer has become known from German patent specification 330 799, in which the fibers to be mixed are supplied to the room by an air stream and which has a rotatable distributor device which is acted upon by the air stream carrying the fibers.

Ausgehend von diesem bekannten Fasermischer liegt der Erfindung die Aufgabe zugrunde, den Fasermischer so auszubilden, dass zugeführte Fasern verschiedener Eigenschaften so sorgfältig miteinander gemischt werden, dass grosse Partien mit durchgehend einheitlichen Eigenschaften hergestellt werden können.Proceeding from this known fiber mixer, the object of the invention is to design the fiber mixer in such a way that supplied fibers of different properties are mixed with one another so carefully that large batches with consistently uniform properties can be produced.

Die Fasern können sich dabei entweder nach ihrer Farbe oder nach ihrer Länge oder nach dem Faserdurchmesser unterscheiden; es können aber auch Fasern verschiedenen Ursprungs miteinander zu mischen sein, beispielsweise Fasern aus Wolle, Baumwolle oder synthetischer Art.The fibers can differ either by their color or by their length or by the fiber diameter; however, fibers of different origins can also be mixed with one another, for example fibers of wool, cotton or synthetic.

Besonders schwierig wird ein Mischen solcher Fasern dann, wenn sich die Faserlängen und Faserdurchmesser, besonders aber die spezifischen Gewichte derselben erheblich voneinander unterscheiden. Dann erfolgt nämlich bei den bekannten Fasermischern stets wieder eine gewisse Entmischung, die dadurch zustandekommt, dass die schwereren Fasern bzw. die Fasern mit der grösseren Sinkgeschwindigkeit sich von den anderen Fasern im Luftstrom mehr oder weniger stark trennen.Mixing such fibers becomes particularly difficult when the fiber lengths and fiber diameters, but especially the specific weights thereof, differ significantly from one another. Then, in the known fiber mixers, there is always a certain segregation, which is caused by the fact that the heavier fibers or the fibers with the higher sinking speed separate more or less strongly from the other fibers in the air flow.

Umso mehr müssen die Fasern durch den Fasermischer gleichmässig verteilt und miteinander vermischt werden, damit eine Partie völlig einheitlichen Aussehens und einheitlicher Eigenschaften erzielt wird.All the more, the fibers have to be evenly distributed and mixed by the fiber mixer so that a batch of completely uniform appearance and properties is achieved.

Bei den bekannten Fasermischern ist es im allgemeinen nicht möglich, die in der Praxis gewünschten Partien bis zu 20t und darüber so sorgfältig zu vermischen, dass am fertigen Produkt keine Unterschiede innerhalb der Partie wahrnehmbar sind.In the known fiber mixers, it is generally not possible to mix the batches desired in practice up to 20 tons and above so carefully that no differences within the batch can be perceived on the finished product.

Die vorstehend genannte Aufgabe wird erfindungsgemäss durch einen Fasermischer nach den Merkmalen des Anspruchs 1 gelöst.The above object is achieved according to the invention by a fiber mixer according to the features of claim 1.

Das in einer der Kammer vorgeschalteten Vorrichtung geöffnete und verwirbelte Fasermaterial wird dem Fasermischer über ein weites Rohr durch einen Luftstrom zugeführt und jetzt noch einmal flockig aufgewirbelt und so verteilt, dass keine Entmischung infolge des bekannten Windsichtungseffektes mehr auftritt. Das wird insbesondere dadurch erreicht, dass der Fasern zuführende Luftstrom, der noch in den Zuführungsrohrstutzen und anschliessend in den drehbaren Rohrstutzen gelangt, nach seinem Austritt aus dem letzteren durch die umlaufende, mit Schaufeln besetzte Trommel so gebrochen wird, dass der gefürchtete Windsichtungseffekt nicht mehr auftritt. Das gemischte Fasergut wird vielmehr völlig gleichmässig in einem gewissen Umkreis verwirbelt und abgelegt, und die Fasern verschiedener Art liegen dann in der Kammer völlig regellos durcheinander derart, dass man fast von einer homogenen Mischung sprechen kann. Jedenfalls ist der optische Eindruck des durch diesen Fasermischer gemischten und abgelegten Fasergutes beispielsweise bei langgestreckten rechteckigen Kammern am einen Ende der Kammer genau so wie an deren anderem Ende. Entsprechend ändern sich auch die sonstigen Eigenschaften der Fasermischung nicht von Ort zu Ort, sondern sind völlig gleichmässig.The fiber material opened and swirled in a device upstream of the chamber is fed to the fiber mixer through a wide tube by an air stream and is now whirled up again and distributed so that no separation due to the known wind separation effect occurs. This is achieved in particular by the fact that the air supplying the fibers, which still gets into the supply pipe socket and then into the rotatable pipe socket, is broken after it emerges from the latter by the rotating drum, which is covered with blades, so that the dreaded wind separation effect no longer occurs . Rather, the mixed fiber material is whirled and deposited completely uniformly in a certain area, and the fibers of various types are then randomly mixed up in the chamber in such a way that one can almost speak of a homogeneous mixture. In any case, the optical impression of the fiber material mixed and deposited by this fiber mixer, for example in the case of elongated rectangular chambers, is exactly the same at one end of the chamber as at the other. Accordingly, the other properties of the fiber mixture do not change from place to place, but are completely uniform.

Um die Mischwirkung noch mehr zu verbessern, ist die horizontale Achse für die Trommel an einem etwa vertikal verlaufenden Arm befestigt, der oberseitig mit dem drehbaren Rohrstutzen drehfest verbunden ist. Die Trommel dreht sich also jetzt nicht nur um ihre horizontale Achse, sondern ausserdem auch noch um eine vertikale Achse, die mit der Mittelachse des Zuführungsrohrstutzens beziehungsweise des drehbaren Rohrstutzens zusammenfällt. Die Trommel kann dabei entweder zylindrisch oder konisch ausgebildet sein.In order to improve the mixing effect even more, the horizontal axis for the drum is attached to an approximately vertically extending arm, which is connected in a rotationally fixed manner on the upper side to the rotatable pipe socket. The drum now rotates not only about its horizontal axis, but also about a vertical axis that coincides with the central axis of the feed pipe socket or the rotatable pipe socket. The drum can be either cylindrical or conical.

Die Trommel ist entweder frei drehbar und wird dann durch die auf die einzelnen Schaufeln auftreffende Luft mit dem Fasergut von selbst in Bewegung versetzt, oder sie ist angetrieben. Der Antrieb kann entweder durch einen besonderen Motor oder auch durch eine Verbindung mit dem Antrieb des drehbaren Rohrstutzens erfolgen.The drum is either freely rotatable and is then set to move by itself with the fiber material by the air impinging on the individual blades, or it is driven. The drive can be done either by a special motor or by a connection to the drive of the rotatable pipe socket.

Die Erfindung wird nachstehend in einem Ausführungsbeispiel anhand der Zeichnung näher erläutert.The invention is explained in more detail below in an exemplary embodiment with reference to the drawing.

Dabei zeigen:

  • Fig. 1 einen Längsschnitt durch einen erfindungsgemässen Fasermischer;
  • Fig. 2 eine Draufsicht auf die Trommel in Richtung des Pfeiles 11-11 in Fig. 1 und
  • Fig.3 eine Draufsicht auf die Vorrichtung in Fig.1.
Show:
  • 1 shows a longitudinal section through a fiber mixer according to the invention;
  • Fig. 2 is a plan view of the drum in the direction of arrow 11-11 in Fig. 1 and
  • 3 shows a plan view of the device in FIG. 1.

In Fig. 1, die zugleich einen Schnitt längs der abgekröpften Schnittebene I-I in Fig. darstellt, ist der Fasermischer mit sämtlichen Einzelteilen dargestellt. Die Fasern werden dem feststehenden Zuführungsrohrstutzen 1 oberseitig durch einen Luftstrom zugeführt, indem dort beispielsweise ein Rohr beziehungsweise ein Rohrkrümmer angeflanscht ist. Unterseitig schliesst sich an diesen festen Zuführungsrohrstutzen ein etwas kürzerer Rohrstutzen 2 an, der den Zuführungsrohrstutzen 1 übergreift und diesem gegenüber drehbar ist. Der Rohrstutzen 2 trägt oberseitig einen radial nach aussen vorstehenden Ring 19, der ein Wälzlager aufnimmt, das eine leichte Drehbarkeit gegenüber dem festen Zuführungsrohrstutzen 1 garantiert. Die Wälzkörper 18 rollen in diesem Falle auf dem äusseren Mantel des Zuführungsrohrstutzens 1 ab, von dem im übrigen ein schmaler Ring 17 nach aussen vorsteht, auf dem die Wälzkörper 18 aufliegen.In Fig. 1, which also represents a section along the cranked section plane I-I in Fig., The fiber mixer is shown with all the individual parts. The fibers are fed to the fixed feed pipe socket 1 on the upper side by an air stream, for example by flanging a pipe or a pipe bend there. On the underside, this fixed feed pipe connection is followed by a somewhat shorter pipe connection 2, which overlaps the supply pipe connection 1 and can be rotated relative to it. The pipe socket 2 carries on the upper side a radially outwardly projecting ring 19 which receives a roller bearing which guarantees easy rotation relative to the fixed feed pipe socket 1. In this case, the rolling elements 18 roll on the outer jacket of the feed pipe socket 1, from which a narrow ring 17 projects outwards, on which the rolling elements 18 rest.

Oberseitig ist das Lager durch eine Scheibe 20 abgeschlossen.The bearing is closed at the top by a disk 20.

Der Drehantrieb des Rohrstutzens 2 erfolgt über den vorgenannten Ring 19, indem sich an diesen aussen ein Reibrad 4 anlegt, das von einem Elektromoior 3 angetrieben wird. Sowohl der Elektromotor als auch das Reibrad sind in einem Vorsprung eines einarmigen Hebels 14 gelagert und geha!tert, der bei 15 schwenkbar in einem Rahmen Üi, 11, 12, 13 gelagert ist. Eine sich an diesem Rahmen abstützende Schraubendruckfeder 16 drückt den Hebel 14 und damit das Reibrad 4 in Richtung auf den Ring 19, so dass ein Antriebsmoment von dem Reibrad auf den Ring und damit auf den Rohrstutzen 2 übertragen werden kann.The rotary drive of the pipe socket 2 takes place via the aforementioned ring 19, in that a friction wheel 4, which is driven by an electric motor 3, is placed on the outside of the latter. Both the electric motor and the friction wheel are mounted and supported in a projection of a one-armed lever 14, which is pivotably mounted at 15 in a frame U i, 11, 12, 13. A helical compression spring 16 supported on this frame presses the lever 14 and thus the friction wheel 4 in the direction of the ring 19, so that a drive torque can be transmitted from the friction wheel to the ring and thus to the pipe socket 2.

An dem drehbaren Rohrstutzen 2 ist aussen ein im wesentlichen vertikal verlaufender Arm 9 fest verbunden, der also bei Drehung des Rohrstutzens 2 mit diesem umläuft.On the rotatable pipe socket 2, an essentially vertically extending arm 9 is firmly connected to the outside, which therefore rotates with the pipe socket 2 when it rotates.

An seinem unteren Ende trägt dieser Arm 9 eine horizontal verlaufende Achse 6, auf der über Wälzlager 21 und 22 und Tragscheiben 23 und 24 eine Trommel 8 drehbar gelagert ist. Diese Trommel ist konisch ausgebildet und am einen Ende durch die Tragscheibe 24 und eine zusätzliche Scheibe 25, am anderen, verjüngten Ende durch eine Scheibe 26 verschlossen. An ihrem Umfang trägt die konische Trommel Schaufeln 7, die von den aus der unteren Öffnung 5 des drehbaren Rohrstutzens 2 herausfallenden Fasern beaufschlagt werden und die Trommel in Drehung versetzen.At its lower end, this arm 9 carries a horizontally extending axis 6, on which a drum 8 is rotatably mounted via roller bearings 21 and 22 and support disks 23 and 24. This drum is conical and closed at one end by the support disk 24 and an additional disk 25, at the other, tapered end by a disk 26. On its circumference, the conical drum carries blades 7, which are acted upon by the fibers falling out of the lower opening 5 of the rotatable pipe socket 2 and set the drum in rotation.

Der Halterahmen für den festen Zuführungsrohrstutzen 1 besteht aus zwei tangential zum Stutzen 1 und paralell zueinander verlaufenden schmalen Trägern 11 und 12 und an deren Ende je eine sie miteinander verbindende Querstrebe 10 beziehungsweise 13.The holding frame for the fixed feed pipe connection 1 consists of two narrow supports 11 and 12 which run tangentially to the connection 1 and parallel to one another and at the end of which a cross strut 10 or 13 connecting them to one another.
