Abstract

The formatting belt curves the strip (24) of wrapper material in the transfer part round the tube of fibrous tobacco material. The formatting belt (21) of the suction conveyor (6) forces a horizontal strip-guide (27) onto the strip of wrapper material, in the transfer part (26). The part (7,17) shaping and forming the tube of tobacco has a horizontal guide part (28) and a guide part (29) sloping towards the formatting belt in the direction of travel (14) in the transfer part. The sloping guide-part defines the top of the tube of fibrous tobacco, and the horizontal guide-part defines the bottom of the fibrous tube.

Description

Die Erfindung betrifft eine Anordnung zum Übergeben eines Faserstranges der tabakverarbeitenden Industrie von einem den Faserstrang aufbauenden und formenden Saugstrangförderer auf ein einen Hüllmaterialstreifen in einem Übergabebereich vorkrümmendes und in einer Formateinrichtung um den Faserstrang herumlegendes Formatband. Eine solche Anordnung ist aus der EP-A-0 497 731 bekannt. Unter einem "Faserstrang der tabakverarbeitenden Industrie" ist in erster Linie ein endloser Strang aus Tabak aber auch aus Filtermaterial zu verstehen, der beim Beispiel eines Tabak-bzw. Zigarettenstranges nach seiner Vorformung, beispielsweise durch Aufschauern eines Tabakstromes aus vereinzelten Tabakfasern an einem Saugstrangförderer, unter kontinuierlicher Querschnittsverjüngung auf den Querschnitt des fertigen Zigarettenstranges in einer Formateinrichtung durch einen Papierstreifen umhüllt wird.The invention relates to an arrangement for transferring a Fiber strands of the tobacco processing industry from one The fiber strand-building and forming suction strand conveyor a pre-curving a strip of wrapping material in a transfer area and in a format device around the fiber strand format tape lying around. Such an arrangement is from the EP-A-0 497 731 known. Under a "fiber strand of the tobacco processing industry" is primarily an endless strand of tobacco but also made from To understand filter material that in the example of a tobacco or. Cigarette rod after its preforming, for example by looking up a stream of tobacco from isolated tobacco fibers on a suction line conveyor, under continuous Cross-sectional taper to the cross-section of the finished cigarette rod in a format device by a paper strip is enveloped.

Der Erfindung liegt die Aufgabe zugrunde, die Anordnung der eingangs bezeichneten Streifen- und Strangfördermittel im Sinne einer baulichen und funktionsmäßigen sowie letzten Endes die Produktqualität des hergestellten Zigarettenstranges bzw. der daraus entstehenden Einzelartikel verbessernden Optimierung weiterzubilden.The invention has for its object the arrangement of Strip and strand conveyors referred to in the introduction a structural and functional as well as ultimately the Product quality of the manufactured cigarette rod or resulting optimization of individual items further education.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß dem im Übergabebereich dem Hüllmaterialstreifen eine im wesentlichen horizontale Streifenführung aufzwingenden Formatband der Saugstrangförderer mit einem im Strangaufbau- und Strangformungsbereich im wesentlichen horizontal verlaufenden Strangführungsabschnitt und einem im Übergabebereich in Förderrichtung gegen das Formatband geneigten Strangführungsabschnitt zugeordnet ist.
Es ist weiterhin von Vorteil, wenn der geneigte Strangführungsabschnitt den Faserstrang oberseitig und der horizontale Streifenführungsabschnitt des Formatbandes den Faserstrang unterseitig begrenzt. Auf diese Weise kann durch die von oben erfolgende trichterartige Verengung der Führungsabschnitte der Faserstrang gezielt auf den auf dem horizontalen unteren Führungsabschnitt in Querrichtung bereits konkav vorgeformten Hüllmaterialstreifen überführt und anschließend faltenfrei umhüllt werden.According to the invention, this object is achieved in that the format belt of the suction strand conveyor which is forced on the wrapping material strip in the transfer area to have an essentially horizontal strip guide is assigned a strand guide section which runs essentially horizontally in the strand build-up and strand forming area and a strand guide section which is inclined in the conveying direction in the conveying direction against the format belt.
It is furthermore advantageous if the inclined strand guide section delimits the fiber strand on the top side and the horizontal strip guide section of the format band delimits the fiber strand on the underside. In this way, the funnel-like narrowing of the guide sections from above allows the fiber strand to be transferred specifically to the wrapping material strip which has already been concavely shaped in the transverse direction on the horizontal lower guide section and then to be wrapped wrinkle-free.

Der mit der Erfindung erzielte Vorteil besteht darin, daß durch die insbesondere im Strangaufbaubereich horizontal verlaufende Anordnung des Saugstrangförderers eine einfachere konstruktive Gestaltung des betreffenden Maschinensektors bei gleichzeitig durch das abknickende bzw. geneigt verlaufende Abgabeende des Saugstrangförderers bewirkter faltenfreier Papierumhüllung des Tabakstranges erreicht wird.The advantage achieved by the invention is that the one that runs horizontally, particularly in the area of strand construction Arrangement of the suction line conveyor a simpler constructive Design of the machine sector concerned at the same time through the kinking or inclined delivery end of the Suction line conveyor caused wrinkle-free paper wrapping of the Tobacco rod is reached.

Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.
Die Figur zeigt die Strangaufbauzone einer Zigarettenstrangmaschine mit Einzelheiten der Strangführung sowie der Führung von Formatband und Zigarettenpapierstreifen.The invention is explained in more detail using an exemplary embodiment shown in the drawing.
The figure shows the strand build-up zone of a cigarette rod machine with details of the strand guide and the guidance of the format tape and cigarette paper strips.

In der Zeichnung ist mit 1 ein nur zum Teil dargestellter Schacht einer Zigarettenmaschine dargestellt, zwischen dessen Seitenwänden 2 Luft entsprechend den Pfeilen 3 nach oben strömt und dabei Tabakfasern 4 mitnimmt. Die Luft strömt durch einen als luftdurchlässiges Förderband ausgebildeten Saugstrangförderer 6 hindurch und gelangt in einem Strangaufbaubereich 7 durch Öffnungen 8 in einer stationären Führung 9, die als Lochboden ausgebildet ist, in eine Unterdruckkammer 11, die über eine Leitung 12 mit einer nicht dargestellten Unterdruckquelle, zum Beispiel der Saugseite eines Ventilators, in Verbindung steht. Der Saugstrangförderer 6 ist über Rollen 13, von denen nur eine dargestellt ist, geführt, von denen mindestens eine angetrieben ist, so daß der Saugstrangförderer 6 eine Bewegung in Richtung des Pfeils 14 ausführt. An seiner Unterseite sammeln sich im Strangaufbaubereich 7 über dem Schacht 1 die Tabakfasern 4 zu einem Tabakstrang 16 an, der in einem Strangformungsbereich 17 von einem bekannten Egalisator 18 in seiner Höhe egalisiert und einem bekannten Format 19 zugeführt wird. Dem Format 19 werden außerdem ein angetriebenes Formatband 21 und ein Zigarettenpapierstreifen 22 zugeführt, die über Umlenkrollen 23 bzw. 24 geführt sind. Der Zigarettenpapierstreifen 22 gelangt bei der Umlenkrolle 23 in einem Übergabebereich 26 des Tabakstranges 16 auf das über eine horizontale Streifenführung 27 geführte Formatband 21, worauf beide zum Format 19 gefördert werden.
Der im Strangaufbau- und Strangformungsbereich 7 bzw. 17 entlang eines horizontalen Strangführungsabschnitts 28 der Führung 9 bewegte Saugstrangförderer 6 wird im Übergabebereich 26 an einem gegen die horizontale Streifenführung 27 des Formatbandes 21 geneigten Strangführungsabschnitt 29 der Führung 9 entlangbewegt und führt dabei den egalisierten Tabakstrang 16 von oben her mit dem bereits im Bereich der horizontalen Streifenführung 27 in Querrichtung konkav vorgeformten Zigarettenpapierstreifen 22 zusammen.In the drawing, 1 shows a shaft of a cigarette machine, only partially shown, between the side walls 2 of which air flows upwards according to the arrows 3 and thereby takes tobacco fibers 4 with it. The air flows through a suction strand conveyor 6 designed as an air-permeable conveyor belt and in a strand build-up area 7 passes through openings 8 in a stationary guide 9, which is designed as a perforated floor, into a vacuum chamber 11, which is connected via a line 12 to a vacuum source, not shown Example of the suction side of a fan. The suction strand conveyor 6 is guided over rollers 13, only one of which is shown, of which at least one is driven, so that the suction strand conveyor 6 executes a movement in the direction of the arrow 14. On its underside, the tobacco fibers 4 accumulate in the strand building area 7 above the shaft 1 to form a tobacco rod 16, the height of which is equalized in a strand forming region 17 by a known leveler 18 and fed to a known format 19. The format 19 is also supplied with a driven format belt 21 and a cigarette paper strip 22, which are guided over deflection rollers 23 and 24, respectively. The cigarette paper strip 22 arrives at the deflection roller 23 in a transfer area 26 of the tobacco rod 16 onto the format belt 21 guided over a horizontal strip guide 27, whereupon both are conveyed to the format 19.
The suction line conveyor 6, which is moved in the line building and line forming area 7 or 17 along a horizontal line guide section 28 of the guide 9, is moved in the transfer area 26 along a line guide section 29 of the guide 9 inclined against the horizontal line guide 27 of the format belt 21 and thereby guides the leveled tobacco line 16 from above together with the cigarette paper strip 22 which has already been concavely shaped in the transverse direction in the region of the horizontal strip guide 27.
