Abstract
Description
Die Erfindung betrifft eine Kanalwange für einen Kanal zum Führen eines Strangs der tabakverarbeitenden Industrie, einen Strangförderer, insbesondere einen Strangförderer einer Zigarettenstrangmaschine, mit einer solchen Kanalwange, und eine Mehrstrangmaschine mit mindestens zwei Strangförderern mit jeweils einem Kanal zum Führen eines Strangs der tabakverarbeitenden Industrie mit einer solchen Kanalwange. Unter einem Strang der tabakverarbeitenden Industrie wird hier insbesondere ein Faserstrang, vorzugsweise aus Schnitttabak verstanden.The invention relates to a channel cheek for a channel for guiding a strand of the tobacco processing industry, a strand conveyor, in particular a strand conveyor of a cigarette rod machine, with such a channel cheek, and a multi-strand machine with at least two strand conveyors each having a channel for guiding a strand of the tobacco processing industry with a such channel cheek. A strand of the tobacco-processing industry is understood to mean in particular a fiber strand, preferably cut tobacco.
Derartige Kanalwangen sind aus dem Stand der Technik bekannt. So zeigt beispielsweise die
Die Saugstrangförderer, die zumeist mit Hilfe der Kanalwangen im Tabakkanal geführt sind, dienen in einer Zigarettenstrangmaschine zusammen mit den Kanalwangen dazu, den Tabak, welcher in Form eines Schauers dem den Boden des Strangführungskanals bildenden Saugstrangförderer zugeführt wird, in einer Strangbildungszone anzusammeln und aus dieser - ggf. durch eine Überschussabnahmeeinrichtung, den sogenannten Trimmer, hindurch - in Form eines Strangs abzufördern.The Saugstrangförderer, which are usually performed with the help of channel cheeks in the tobacco channel, serve in a cigarette rod machine together with the channel cheeks, the tobacco, which is supplied in the form of a shower to the bottom of the strand guide channel forming Saugstrangförderer in a strand formation zone and from this - if necessary by an excess removal device, the so-called trimmer, through - in the form of a strand.
Der Trimmer wird dabei in der Regel mit einer Einrichtung zur Einbringung einer Kopfverstärkung in den Faserstrang versehen. So zeigt beispielsweise die
Die hohe Geschwindigkeit der modernen Zigarettenstrangmaschinen stellen jedoch hohe Anforderungen an die in direktem Kontakt mit dem Faserstrang stehenden Kanalwangen.However, the high speed of modern cigarette rod making machines make high demands on the standing in direct contact with the fiber strand channel cheeks.
Aufgabe der vorliegenden Erfindung ist es, die aus dem Stand der Technik bekannten Kanalwangen und Strangförderer zu verbessern.The object of the present invention is to improve the channel cheeks and strand conveyors known from the prior art.
Diese Aufgabe wird durch eine Kanalwange gemäß Anspruch 1, durch einen Strangförderer gemäß Anspruch 11, und durch eine Mehrstrangmaschine nach Anspruch 12 gelöst.This object is achieved by a channel cheek according to claim 1, by a rope conveyor according to
Die Erfindung schließt die Erkenntnis ein, dass alle direkt oder indirekt mit dem Faserstrang in Kontakt stehenden Teile, also auch die eingangs genannten Kanalwangen, den Verlauf und das Verhalten des Faserstrangs deutlich beeinflussen. Insbesondere unmittelbar stromabwärts der Trimmerscheiben, in deren Bereich die Kanalwangen oftmals seitlich zurücktreten, haben die Kanalwangen die Aufgabe, den Faserstrang wieder sanft auf seine gewünschte Form zu zentrieren.The invention includes the knowledge that all directly or indirectly in contact with the fiber strand parts, including the channel cheeks mentioned above, the course and behavior of the fiber strand significantly influence. In particular immediately downstream of the trimmer discs, in the region of which the channel cheeks often recede laterally, the channel cheeks have the task of gently centering the fiber strand again to its desired shape.
Dabei müssen die Kanalwangen insbesondere die von den Trimmerscheiben in den Faserstrang eingebrachte Kopfverstärkung sanft aus der größeren Weite des Tabakkanals im Bereich der Trimmerscheiben in die schmalere Weite des Kanals stromabwärts der Trimmer zurückführen. Hierzu wurde im vorstehend genannten Stand der Technik die Kanalwange mit einer Kante versehen. Diese Kante definiert zumeist einen oberen, dem Saugförderband näherliegenden Abschnitt mit schmalerer Kanalweite, und einen unteren, der Unterseite der Kanalwange näherliegenden Abschnitt der Kanalwange mit größerer Weite. Im Stand der Technik verläuft diese Kante nicht parallel zum Saugförderband. Gemäß der vorliegenden Erfindung verläuft die Kante jedoch erstmals im wesentlichen parallel zu dem Saugförderband.In this case, the channel cheeks in particular have to recirculate the head reinforcement introduced by the trimmer discs into the fiber strand gently from the larger width of the tobacco channel in the region of the trimmer discs into the narrower width of the channel downstream of the trimmer. For this purpose, the channel cheek was provided with an edge in the aforementioned prior art. This edge usually defines an upper, closer to the suction conveyor section narrower channel width, and a lower, closer to the underside of the channel cheek section of the channel cheek with greater width. In the prior art, this edge is not parallel to the suction conveyor belt. However, according to the present invention, the edge for the first time runs substantially parallel to the suction conveyor belt.
Ausführungsformen der erfindungsgemäßen Kanalwangen weisen daher insbesondere den Vorteil auf, dass ein unerwünschtes Aufweiten des Tabakvlieses des Strangs im Bereich der Kante vermieden wird.Therefore, embodiments of the channel cheeks according to the invention have the particular advantage that unwanted widening of the tobacco fleece of the strand in the region of the edge is avoided.
Auch wird entgegen dem Stand der Technik bei diesen Ausführungsformen vorteilhaft vermieden, dass Tabak des Strangs an der Kante hängen bleibt. Letzteres hätte eine unerwünschte Verstopfung des Tabakkanals zur Folge oder eine Verschlechterung der Qualität der Kopfverstärkung.Also, contrary to the prior art in these embodiments, it is advantageously avoided that tobacco of the strand gets caught on the edge. The latter would result in an undesirable obstruction of the tobacco channel or a deterioration in the quality of the head reinforcement.
Diese Ausführungsformen der Erfindung erzielen somit gegenüber dem Stand der Technik eine sanftere Rückführung des Faserstranges nach der Trimmung.These embodiments of the invention thus achieve, compared to the prior art, a gentler recycling of the fiber strand after trimming.
Bevorzugt ist es, wenn der Kanal eine Förderrichtung aufweist, und der untere Abschnitt zumindest entlang eines Teils seiner Erstreckung in Förderrichtung und von der Aufnahme aus gesehen gegenüber dem oberen Abschnitt zurückspringt. Der zurückspringende Teil kann so den die Kopfverstärkung aufweisenden Teil des Faserstrangs besser aufnehmen.It is preferred if the channel has a conveying direction, and the lower portion at least along part of its extension in the conveying direction and viewed from the receptacle relative to the upper portion returns. The recessed part can thus better absorb the head reinforcement having part of the fiber strand.
Besonders bevorzugte Ausführungsbeispiele der Erfindung zeichnen sich dadurch aus, dass der untere Abschnitt entlang verschiedener Teile seiner Erstreckung in Förderrichtung gegenüber dem oberen Abschnitt verschieden stark, bevorzugt abnehmend, weiter bevorzugt linear abnehmend, zurückspringt. Auf diese Weise kann die Kopfverstärkung bzw. der Tabakvlies im Bereich der Kopfverstärkung besonders sanft aufgefangen und in die gewünschte Bahn gelenkt werden.Particularly preferred embodiments of the invention are characterized in that the lower portion along different parts of its extension in the conveying direction relative to the upper portion of different strength, preferably decreasing, more preferably linear decreasing, springs back. In this way, the head reinforcement or the tobacco mat in the region of the head reinforcement can be collected very gently and directed into the desired path.
Bei einer anderen bevorzugten Ausführungsform der Erfindung erstreckt sich der untere Abschnitt entlang verschiedener Teile seiner Erstreckung in Förderrichtung von der Aufnahme aus gesehen verschieden weit, bevorzugt zunehmend, weiter bevorzugt linear zunehmend, in den Kanal.In another preferred embodiment of the invention, the lower portion extends along different parts of its extension in the conveying direction from the receptacle different, preferably increasingly, more preferably linearly increasing, in the channel.
Besonders bevorzugt findet die erfindungsgemäße Kanalwange in Mehrstrangmaschinen zur gleichzeitigen Herstellung von mindestens zwei Strängen der tabakverarbeitenden Industrie Verwendung, bei denen mindestens zwei Strangförderer nach Anspruch 11 vorgesehen sind, wobei die jeweiligen Kanäle zum Führen des jeweiligen Strangs jedes der Strangförderer zumindest im Bereich der jeweiligen Kante in ihren Förderebenen zueinander beabstandet sind.The channel cheek according to the invention is particularly preferably used in multi-strand machines for the simultaneous production of at least two strands of the tobacco-processing industry, in which at least two strand conveyors are provided according to
Weitere bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Further preferred embodiments of the invention are specified in the subclaims.

Die Funktionsweise der Zigarettenstrangmaschine 50 ist wie folgt:Fig. 1 shows a perspective view of a single-stranded cigarette
Von einer Schleuse 1 wird ein Vorverteiler 2 portionsweise mit Tabak beschickt. Eine Entnahmewalze 3 des Vorverteilers 2 ergänzt gesteuert einen Vorratsbehälter 4 mit Tabak, aus dem ein Steilförderer 5 Tabak entnimmt und einen Stauschacht 6 gesteuert beschickt. Aus dem Stauschacht 6 entnimmt eine Stiftwalze 7 einen gleichförmigen Tabakstrom, der von einer Ausschlagwalze 8 aus den Stiften der Stiftwalze 7 herausgeschlagen und auf ein mit konstanter Geschwindigkeit umlaufendes Streutuch 9 geschleudert wird. Ein auf dem Streutuch 9 gebildetes Tabakvlies wird in eine Sichteinrichtung 11 geschleudert, die im Wesentlichen aus einem Luftvorhang besteht, den größere bzw. schwerere Tabakteile passieren, während alle anderen Tabakteilchen von der Luft in einen von einer Stiftwalze 12 und einer Wand 13 gebildeten Trichter 14 gelenkt werden. Von der Stiftwalze 12 wird der Tabak in einen Strangführungskanal 16 gegen einen Strangförderer 17 geschleudert, an dem der Tabak mittels in eine Unterdruckkammer 18 gesaugter Luft gehalten und ein Tabakstrang aufgeschauert wird. Für eine detaillierte Beschreibung eines solchen Strangförderers 17 sei bspw. auf die

Zur allgemeinen Beschreibung der Verwendung derartiger Kanalwangen 1 und zu der Art und Weise ihres Einbaus sei beispielsweise auf die eingangs erwähnte
Die dargestellte Kanalwange 60 weist eine Oberfläche 62 auf, die einer zweiten, in Förderrichtung parallel verlaufenden, nicht dargestellten Kanalwange des Kanals 16 des Saugstrangförderers 17 der Zigarettenstrangmaschine 50 zur Bildung des Kanals 16 zugewandt ist. Auf der Oberfläche 62 ist in Form eines Vorsprungs 64 eine Aufnahme zum Aufnehmen des zugeordneten Strangförderers 17 ausgebildet.The illustrated
In der Figur 2 unterhalb des Vorsprungs 64 und parallel zu diesem verlaufend ist eine Kante 66 vorgesehen, die entlang eines Teils 68 der Kanalwange 60 einen oberen, dem Vorsprung 64 näherliegenden Abschnitt 70 und einen unteren, von dem Vorsprung 64 weiter abliegenden Abschnitt 72 definiert. Der untere Abschnitt 72 springt, beginnend an dem Punkt 74, von dem Vorsprung 64 aus gesehen entlang des Teils 68 der Kanalwange 60 gegenüber dem oberen Abschnitt 70 zurück. Dieses Zurückspringen nimmt in Förderrichtung von dem Punkt 74 ausgehend linear ab, bis der untere Abschnitt 72 an einem Übergang 76 stetig in die Oberfläche 62 der Kanalwange 60 übergeht, welche Oberfläche 62 auch die Oberfläche des oberen Abschnitts 70 bildet.In the figure 2 below the
