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.

Dabei kann es sich um eine quadratische Kammer handeln, in der der Fasermischer unterhalb des Daches beziehungsweise der Decke fest eingebaut ist. Es kann sich aber auch um eine langgestreckte rechteckige Materialkammer handeln, die über eine Teleskoprohreinrichtung, am einen Ende beginnend, gefüllt wird.This can be a square chamber in which the fiber mixer is permanently installed below the roof or ceiling. However, it can also be an elongated rectangular material chamber which is filled via a telescopic tube device, beginning at one end.

Derartige Kammern sind bekannt und es werden dabei verschiedene Arten von Fasermischern verwendet, um zugeführte Fasern verschiedener Art miteinander so gut wie möglich zu mischen und in der Kammer abzulegen.Such chambers are known and different types of fiber mixers are used in order to mix supplied fibers of different types with one another as well as possible and to deposit them in the chamber.

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 beziehungsweise 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 each other. 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 with one another by the fiber mixer so that a batch of completely uniform appearance and uniform properties is achieved.

Bei den bekannten Fasermischern ist es im allgemeinen nicht möglich, die in der Praxis gewünschten Partien bis zu 20 t 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 t and above so carefully that no differences within the batch can be perceived on the finished product.

Der Erfindung liegt die Aufgabe zugrunde, einen Fasermischer zu schaffen, der durch einen Luftstrom zugeführte Fasern verschiedener Eigenschaften so sorgfältig miteinander mischt, daß große Partien mit durchgehend einheitlichen Eigenschaften hergestellt werden können.The invention has for its object to provide a fiber mixer that mixes fibers of different properties supplied by an air stream so carefully that large batches can be produced with consistently uniform properties.

Diese Aufgabe wird erfindungsgemäß durch einen Fasermischer nach den Merkmalen des Anspruchs 1 gelöst.This object is achieved 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 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 regelos 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 genauso 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 through an air stream and is now whirled up again and distributed so that no separation due to the known wind sifting effect occurs occurs. This is achieved in particular in that the fiber-feeding air flow, which still enters the feed pipe socket and then the rotatable pipe socket, is broken after its exit from the latter by the rotating drum, which is covered with blades, in such a way that the dreaded wind separation effect no longer occurs. Rather, the mixed fiber material is whirled and deposited completely uniformly in a certain radius and the fibers of different types then lie in the chamber completely randomly 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 is, for example in the case of elongated rectangular chambers, at one end of the chamber as well as at the other end. 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 also about a vertical axis which coincides with the central axis of the feed pipe socket or of 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 automatically moved with the fiber material by the air hitting the individual blades sets, 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 is a top view of the device in FIG. 1.

In Fig. 1, die zugleich einen Schnitt längs der abgekröpften Schnittebene I-I in Fig. 3 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 cropped section plane II in Fig. 3, 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 a radially outwardly projecting ring 19 on the top side, which receives a roller bearing that guarantees easy rotation relative to the fixed feed pipe socket 1. The rolling elements 18 roll in this case 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 Elektromotor 3 angetrieben wird. Sowohl der Elektromotor als auch das Reibrad sind in einem Vorsprung eines einarmigen Hebels 14 gelagert und gehaltert, der bei 15 schwenkbar in einem Rahmen 10, 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 connection 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, engages on the outside of the latter. Both the electric motor and the friction wheel are mounted and held in a projection of a one-armed lever 14, which is pivotally mounted at 15 in a frame 10, 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 on the outside, which therefore rotates when the pipe socket 2 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 parallel 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 socket 1 consists of two narrow supports 11 and 12 which run tangentially to the socket 1 and parallel to one another and at the end of which a cross strut 10 or 13 connecting them to one another.
