Abstract
Description
Die Erfindung betrifft ein Verfahren zum Vereinzeln von auf
kanalisierten Flugbahnen bewegten Tabak- oder dergleichen
Fasern nach dem Oberbegriff des Anspruchs 1. Ein derartiges
Verfahren ist bereits aus DE-C-954137 bekannt.The invention relates to a method for separating on
channeled trajectories moving tobacco or the like
Fibers according to the preamble of
Die Erfindung betrifft außerdem eine Vorrichtung zum Vereinzeln von durch ein Beschleunigungsmittel in durch Kanalwände begrenzte Flugbahnen überführte Tabakfasern zur Durchführung des Verfahrens nach den Ausprüchen 1-3.The invention also relates to a device for separating from through an accelerator into through channel walls limited trajectories to carry tobacco fibers the procedure according to claims 1-3.
Unter dem Begriff "dergleichen Fasern" werden allgemein Fasern
aus rauchfähigem Material, beispielsweise auch aus Tabakersatzstoffen
verstanden.
Bei der Herstellung von Zigaretten kommt der Einhaltung
bestimmter Qualitätsmerkmale der Endprodukte, d. h. der
fertigen Zigaretten oder Filterzigaretten eine besondere
Bedeutung zu. Diese Qualitätsmerkmale betreffen jeweils in
definierter Schwankungsbreite diverse Produkteigenschaften, wie
die Gleichmäßigkeit der Tabakverteilung in den Zigaretten,
Gewichtsschwankungen, Füllkraft, Härte, Faserlänge und Kopfqualität
der Zigaretten.
Die genannten Qualitätsmerkmale hängen unter anderem entscheidend
von einer möglichst kompletten Vereinzelung, gleichmäßigen
Verteilung und Aufschüttung der Tabakfasern im sogenannten
Verteiler der Zigarettenmaschine ab.
Es sind bereits vielfältige Versuche unternommen worden, um
eine möglichst komplette Vereinzelung der Fasern zu erreichen,
indem Tabak im Verteiler der Zigarettenmaschine mehrfach unter
Auflösung von Verklumpungen von einem Förderer auf einen nachgeordneten
Förderer überführt und dabei zunehmend vereinzelt
wird (US-Patente 3 757 800, 3 825 152) oder mit Hilfe von
unterschiedlich schnell rotierenden, miteinander kämmenden und
mit Mitnehmern besetzten Walzen unter Auseinanderreißen von
Verklumpungen vereinzelt wird (US-Patent 4 036 239). The term “similar fibers” generally means fibers made of smokable material, for example also made of tobacco substitutes.
In the production of cigarettes, compliance with certain quality characteristics of the end products, ie the finished cigarettes or filter cigarettes, is of particular importance. These quality features relate to various product properties in a defined range of variation, such as the uniformity of the tobacco distribution in the cigarettes, weight fluctuations, filling power, hardness, fiber length and head quality of the cigarettes.
The quality features mentioned depend crucially, among other things, on the most complete separation possible, even distribution and filling of the tobacco fibers in the so-called distributor of the cigarette machine.
Various attempts have already been made to achieve as complete a separation of the fibers as possible, in that tobacco in the distributor of the cigarette machine is transferred several times from a conveyor to a downstream conveyor with resolution of clumps and is thereby increasingly separated (US Patents 3,757,800, 3,825,152) or with the aid of rollers rotating at different speeds, meshing with one another and equipped with carriers, with the tearing apart of clumps (US Pat. No. 4,036,239).
Durch die dabei zum Teil recht unsanften mechanischen Einwirkungen auf den Tabak werden die Tabakfasern in unerwünschter Weise verkürzt.Due to the sometimes very rough mechanical effects on the tobacco the tobacco fibers become undesirable Way shortened.
Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen für eine den Tabak schonende Vereinzelung der Tabakfasern zu treffen.The invention has for its object measures for to separate the tobacco fibers carefully.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die
Tabakfasern entlang ihrer Flugbahn wechselweise von gegenüberliegenden
Seiten her durch im wesentlichen quer zur Bewegungsrichtung
bzw. mit einer Komponente in Bewegungsrichtung der
Tabakfasern geführte Blasluft beaufschlagt werden. Durch das
wechselweise Anblasen eines derartigen Tabakschauers werden die
Tabakfasern mehrmals aus ihrer Hauptbewegungsrichtung abgelenkt,
wobei die schnellere seitliche Luftströmung Verklumpungen löst
und die Tabakfasern vereinzelt.
Ein optimaler Löse- und Vereinzelungseffekt wird nach einer
Weiterbildung dadurch erzielt, daß die Tabakfasern an wechselweise
versetzt gegenüberliegenden Stellen der die Flugbahnen
begrenzenden Seiten durch die Blasluft beaufschlagt werden.This object is achieved in that the tobacco fibers along their trajectory are acted upon alternately from opposite sides by blowing air guided essentially transversely to the direction of movement or with a component in the direction of movement of the tobacco fibers. By alternately blowing such a tobacco shower, the tobacco fibers are deflected several times from their main direction of movement, the faster lateral air flow loosening clumps and separating the tobacco fibers.
According to a further development, an optimal release and separation effect is achieved in that the tobacco fibers are acted upon by the blown air at alternately offset locations on the sides delimiting the trajectories.
Zweckmäßigerweise erstrecken sich die Flugbahnen in im wesentlichen vertikaler Fallrichtung der Tabakfasern.The trajectories expediently extend in substantially vertical fall direction of the tobacco fibers.
Die Vorrichtung zur Durchführung des eingangs bezeichneten Verfahrens wird gebildet durch entlang der Flugbahn der Tabakfasern wechselweise an gegenüberliegenden Kanalwänden austretende, im wesentlichen quer zur Flugbahn bzw. mit einer Komponente in Flugrichtung der Tabakfasern ausgerichtete Blasluftöffnungen. Auf diese Weise läßt sich eine gezielte, konzentrierte, schnelle Blasluftströmung auf den vorbeifliegenden Tabakschauer richten, der damit abwechselnd gegen die einander gegenüberliegenden Kanalwände umgelenkt und dabei aufgefächert bzw. in sich gelöst und bezüglich seiner Fasern vereinzelt wird. The device for carrying out the input Process is formed by following the trajectory of the tobacco fibers alternately emerging on opposite channel walls essentially across the trajectory or with a Blown air openings component oriented in the direction of flight of the tobacco fibers. In this way, a targeted, concentrated, fast blown air flow on the flying past A tobacco shower aimed alternately against each other opposite channel walls redirected and fanned out or dissolved in itself and separated with respect to its fibers.
Zur Verstärkung und Optimierung des Effektes sind nach einem weiteren Vorschlag die Blasluftöffnungen an wechselweise versetzt gegenüberliegenden Steilen der Kanalwände angeordnet.To reinforce and optimize the effect are after a Another suggestion to alternately offset the blown air openings opposite parts of the channel walls.
Die Blasluftöffnungen können im Sinne der Erfindung auf unterschiedliche
Weise gestaltet sein, so zum Beispiel als
Bohrungsreihen ausgeführt sein. Nach einer bevorzugten erfindungsgemäßen
Ausgestaltung sind die Blasluftöffnungen als sich
über die Breite der Kanalwände erstreckende Schlitze ausgebildet.
Die erfindungsgemäße Blasluftablenkung läßt sich auf vorteilhafte
Weise in einen üblichen Verteiler einer Zigarettenmaschine
integrieren, bei dem die Kanalwände einen im wesentlichen
senkrechten Fallschacht für die Tabakfasern begrenzen.The blown air openings can be designed in different ways within the meaning of the invention, for example they can be designed as rows of holes. According to a preferred embodiment of the invention, the blown air openings are designed as slots which extend over the width of the channel walls.
The blown air deflection according to the invention can advantageously be integrated into a conventional distributor of a cigarette machine, in which the channel walls delimit a substantially vertical chute for the tobacco fibers.
Bei einer derartigen Anordnung lassen sich die Blasluftöffnungen
nach einer Ausgestaltung am besten dadurch realisieren,
daß die Blasluftöffnungen in die Kanalwände integrierten
Düsenkästen zugeordnet sind.
Die als Vorbedingung für die seitliche Blasluftbeaufschlagung
erforderlichen Flugbahnen der Tabakfasern lassen sich nach
einem zusätzlichen Vorschlag am besten dadurch erzielen, daß
das Beschleunigungsmittel eine rotierende, mit einer Tabak aus
einem Stauschacht austragenden Entnahmewalze zusammenwirkende
Schlägerwalze ist.
Um die auf diese Weise erzielte komplette Vereinzelung der
Tabakfasern für den weiteren Strangaufbauprozeß zu erhalten und
nutzbar zu machen, ist außerdem vorgesehen, daß der Fallschacht
unterseitig in eine Tabakfasern durch eine Querluftströmung in
eine Strangaufbauzone überführende Sichteinrichtung einmündet.With such an arrangement, the blown air openings can best be realized according to one embodiment in that the blown air openings are assigned to nozzle boxes integrated in the channel walls.
The trajectories of the tobacco fibers required as a prerequisite for the lateral blowing air can best be achieved, according to an additional proposal, in that the accelerating means is a rotating beater roller which interacts with a tobacco discharging roller from a storage chute.
In order to maintain and utilize the complete separation of the tobacco fibers achieved in this way for the further strand building process, it is also provided that the chute opens on the underside of a tobacco fibers through a cross-air flow into a sighting device that transports a strand building zone.
Der mit der Erfindung erzielte Vorteil besteht darin, daß der Tabak durch das versetzte seitliche Anblasen aus seiner vorgegebenen Flugbahn mehrmals abgelenkt und dabei auf sanfte, Tabak schonende Weise vereinzelt wird. Dieser stärker vereinzelte und in seiner Faserlänge erhalten gebliebene Tabak bewirkt letzten Endes eine gleichmäßigere Tabakverteilung, geringere Gewichtsschwankungen, eine größere Härte sowie eine gleichmäßigere, bessere Kopfqualität der Zigaretten.The advantage achieved by the invention is that Tobacco through the offset side blowing from its predetermined The trajectory is deflected several times and thereby on gentle, Tobacco sparing way is isolated. This more isolated and tobacco preserved in its fiber length ultimately results in a more even tobacco distribution, less weight fluctuations, greater hardness and a smoother, better head quality of the cigarettes.
Die Erfindung wird nachstehend anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is described below with reference to the drawing illustrated embodiment explained in more detail.
Die Figur zeigt schematisch den Verteiler einer Zigarettenstrangmschine im Längsschnitt.The figure shows schematically the distributor of a cigarette rod machine in longitudinal section.
Der zum Verständnis der Erfindung nur zum Teil dargestellte
Verteiler weist einen Stauschacht 1 mit einem Tabakvorrat 2 und
einer Entnahmevorrichtung 3 auf, welche aus einer Entnahmewalze
4 und einer Schlägerwalze 6 besteht. Der von der Entnahmevorrichtung
3 aus dem Stauschacht 1 entnommene Schauer 7 aus
Tabakfasern gelangt in einen sich trichterförmig verengenden
Fallschacht 8, an dessen Unterseite eine einen Vorsichter
bildende Sichteinrichtung 9 durch eine Querluftströmung aus
einer Druckkammer 11 zugeordneten Blasdüsen 12 die aus dem
Fallschacht 8 austretenden Tabakfasern in eine nachfolgend
beschriebene Strangaufbauzone überführt. Der quergerichtete
Sichtluftstrom trennt leichtere Tabakfasern 13 von schwereren
Tabakfasern 14 (Tabakrippen) und fördert sie in Richtung des
Pfeils 16 zur Strangaufbauzone ab. Einige leichtere Tabakfasern
13 sinken mit den schwereren Tabakrippen 14 nach unten. Sie
gelangen durch eine Zellenradschleuse 17 in einen Sichtschacht
18, in welchem die schwereren Tabakrippen 14 weiter nach unten
sinken und ausgetragen werden, während die leichteren Tabakfasern
13 infolge der Injektorwirkung eines Blasluftstrahls aus
einer einen Nachsichter bildenden Düse 19 nach oben steigen und
in den Strom der leichteren Fasern 13 zurückgeführt werden. Mit
Unterstützung weiterer Blasluftdüsen 21 einer Druckkammer 22
werden die Tabakfasern auf eine Führungsbahn in Gestalt einer
Führungsfläche 23 überführt, auf der sie zu einem Tabakstrom 24
aufgelockerter und ausgebreiteter Tabakfasern aufgebaut werden,
wobei sich Blasluft und Tabakpartikel zu einer dicht an der
Führungsfläche 23 entlangbewegten Wandströmung ausbilden. Zur
Unterstützung der weiteren Förderung des ausgebreiteten und
aufgelockerten Tabakstroms 24 an der Führungsfläche 23 entlang
sind Blasluftdüsen 26 einer Druckkammer 27 sowie gegebenenfalls
weitere im Verlauf der Führungsfläche 23 angeordnete, in der
Zeichnung aber nicht dargestellte Blasluftdüsen vorgesehen.Only partially shown for understanding the invention

Der aufgelockerte und ausgebreitete Tabakstrom 24 gelangt in
einer Strangaufbauzone 28 zu einem Saugstrangförderer 29, an
den durch die Saugwirkung einer Unterdruckkammer 31 von der
Rückseite her ein Saugzug zum Bilden und Halten eines Tabakstranges
angelegt ist. Überschüssige Blasluft entweicht durch
ein Sieb 32 in einen Entspannungsraum 33.
Der Saugstrangförderer 29 läuft in einem Tabakkanal 34 um, der
von zwei Kanalwangen 36 und 37 seitlich begrenzt wird. Der
Endabschnitt 23a der Führungsfläche 23 ist auf eine der Kanalwangen
36 ausgerichtet, so daß ein lückenloser, glatter Übergang
der Führungsfläche zum Tabakkanal 34 gewährleistet ist.
Der Endabschnitt 23a der Führungsfläche 23 ist als um eine
Schwenkachse 38 abschwenkbarer Leitkörper 39 ausgebildet, um
eine bessere Zugänglichkeit der Vorrichtung bei Störungen zu
gewährleisten.
Nach der Erfindung dient die den Tabak aus der Entnahmewalze 4
herausschlagende Schlägerwalze 6 als Beschleunigungsmittel für
den Tabakschauer 7, der auf diese Weise in eine abwärtsgerichtete
Hauptflugbahn (Pfeil 41) überführt wird. Der Fallschacht 8
ist von gegenüberliegenden, nach unten konvergierenden Kanalwänden
42 und 43 begrenzt, in die wechselweise versetzte Blasluftöffnungen
in Form von sich über die Breite der Kanalwände
(senkrecht zur Zeichenebene) erstreckenden Schlitzen 44 bzw. 46
eingelassen sind. Die Schlitze 44 und 46 sind in wesentlichen
quer bzw. mit einer leichten Komponente in Richtung der Flugbahn
41 des Tabakschauers 7 ausgerichtet. Die Schlitze 44 und
46 werden aus an der Rückseite der Kanalwände 42 und 43 angeordneten
Düsenkästen 47 bzw. 48 mit Blasluft gespeist.
Durch den wechselweise gegen den abwärts geschleuderten Tabakschauer
7 im wesentlichen quergerichteten Blasluftstrom aus den
Schlitzen 44 und 46 wird der Tabakschauer 7 wechselweise aus
seiner Hauptflugbahn 41 abgelenkt und die in ihm enthaltenen
