Description

Die Erfindung betrifft eine Vorrichtung zum Fördern eines Stranges der tabakverarbeitenden Industrie mit einer Luftdurchlässe aufweisenden Führung für ein den Strang förderndes, von Saugluft durchströmtes Band, das am Grunde eines Kanals läuft.The invention relates to a device for conveying a strand of tobacco processing Industry with an air passage guide for a strand-promoting, from Belt through which suction air flows and which runs at the bottom of a channel.

Unter einem "Strang der tabakverarbeitenden Industrie" wird insbesondere ein Faserstrang, vorzugsweise aus Schnittabak, verstanden.Under a "strand of the tobacco processing industry" is in particular a fiber strand, preferably from cut tobacco, understood.

In einer Maschine zum Herstellen eines Zigarettenstranges (Zigarettenstrangmaschine) wird einem den Boden eines Strangführungskanals (Tabakkanal) bildenden, umlaufenden Strangförderer Tabak in Form eines Schauers aus vereinzelten Tabakfasern zugeführt, in einer Strangbildungszone im Tabakkanal auf dem Strangförderer angesammelt und als Tabakstrang aus der Strangbildungszone abgefördert. Der Tabakstrang wird anschließend durch Überschußabnahme vergleichmäßigt, bevor er im weiteren Verlauf des Herstellungsprozesses durch Umhüllen mit einem Hüllmaterialstreifen zu einem Zigarettenstrang verarbeitet und schließlich in Tabakstäbe einfacher oder mehrfacher Gebrauchslänge zerschnitten wird. Als Strangförderer wird in modernen Maschinen in der Regel das Untertrum eines Strangförderbandes benutzt, an welchem der angesammelte Faserstrang hängend gefördert wird. Das Strangförderband wird von seiner Rückseite her mit Unterdruck beaufschlagt, so daß durch das Strangförderband hindurch ein die Tabakfasern haltender Saugzug entsteht. Man bezeichnet diese Art von Förderern auch als Saugstrangförderer. Das Fördertrum des Strangförderbandes erstreckt sich im Tabakkanal vom Anfang der Strangbildungszone durch den Bereich der Überschußabnahmeeinrichtung bis zu seinem Abgabeende, an welchem der gebildete Tabakstrang an eine Strangeinheit abgegeben wird. In der Strangeinheit wird der Tabakstrang mit dem Hüllmaterialstreifen umhüllt, so daß ein Zigarettenstrang entsteht, der schließlich zu Zigaretten oder Filterzigaretten weiterverarbeitet wird. Die Länge der Förderstrecke des Saugstrangförderers und die hohe Geschwindigkeit der modernen Strangmaschinen stellen hohe Anforderungen an den Strangförderer und die den Lauf des Strangförderers beeinflussenden Führungsmittel. In a machine for producing a cigarette rod (cigarette rod machine) becomes a circumferential one that forms the bottom of a strand guide channel (tobacco channel) Strand conveyor tobacco in the form of a shower made of isolated tobacco fibers, in a strand formation zone in the tobacco channel accumulated on the strand conveyor and as Extract of tobacco from the strand formation zone. The tobacco strand is then equalized by decrease in excess before it continues in the course of the manufacturing process by wrapping a strip of wrapping material into a cigarette rod processed and finally cut into single or multiple tobacco rods becomes. The lower strand is usually used as a strand conveyor in modern machines a strand conveyor belt, on which the accumulated fiber strand hanging is promoted. The strand conveyor belt is subjected to negative pressure from the rear, so that a suction train holding the tobacco fibers passes through the strand conveyor belt arises. This type of conveyor is also known as a suction line conveyor. The The conveyor belt of the strand conveyor belt extends from the beginning of the tobacco channel Strand formation zone through the area of the excess decrease device to its Dispensing end at which the tobacco rod formed is delivered to a strand unit becomes. The tobacco rod is wrapped in the wrapping material strip in the strand unit, see above that a cigarette rod is formed, which is finally processed into cigarettes or filter cigarettes becomes. The length of the conveyor line of the suction line conveyor and the high speed of modern strand machines place high demands on the strand conveyor and the guide means influencing the run of the strand conveyor.

Als der eingangs bezeichneten Vorrichtung nächstkommender Stand der Technik zeigt die GB-A-974 821 einen derartigen Saugstrangförderer zum Aufbauen und Führen eines unumhüllten Tabakstranges.As the closest prior art to the device referred to at the outset, FIG GB-A-974 821 discloses such a suction line conveyor for building and guiding an uncovered one Tobacco rod.

Weitere vergleichbare Vorrichtungen an Zigarettenstrangmaschinen mit Strangförderbändern der vorbeschriebenen Art sind beispielsweise in der US-PS 4 805 641 und der US-PS 4 344 526 dargestellt.
Desweiteren ist in der GB-A-629 853 eine auf den eingangs bezeichneten Saugstrangförderer folgende Strangeinheit in Gestalt einer Formateinrichtung offenbart, deren einen Hüllstreifen um den Tabakstrang herumschlagende Führungsbahn mit in Förderrichtung aneinandergereihten Auflagesegmenten unterschiedlicher Materialbeschaffenheit versehen ist.Further comparable devices on cigarette rod machines with strand conveyor belts of the type described above are shown, for example, in US Pat. No. 4,805,641 and US Pat. No. 4,344,526.
Furthermore, GB-A-629 853 discloses a line unit following the suction line conveyor described at the beginning in the form of a format device, the guide track of which wraps around an envelope strip around the tobacco line is provided with support segments of different material properties lined up in the direction of conveyance.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine Vorrichtung der eingangs beschriebenen Art im Sinne einer optimalen Anpassung an wechselnde Betriebsbedingungen weiter zu verbessern.The object underlying the invention is a device of the beginning described type in the sense of an optimal adaptation to changing operating conditions continue to improve.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der durch spezifische Aneinanderreihung von Einzelelementen/Segmenten mit unterschiedlichen Luftdurchlässen gebildeten Führung ein definiertes Strömungsprofil über die Länge des Tabakkanals einstellbar ist.This object is achieved in that by the specific sequence of individual elements / segments with different air passages Guide a defined flow profile adjustable over the length of the tobacco channel is.

Weiterbildungen und weitere Ausgestaltungen der Erfindung sind den untergeordneten Ansprüchen zu entnehmen.Further developments and further refinements of the invention are the subordinate claims refer to.

Die Erfindung bietet den Vorteil, daß die relativ kleinen Einzelelemente aus hochverschleißfestem Material, z. B. aus Hartmetall oder Keramik, bestehen können, ohne so teuer zu werden, wie eine ganze Führungsfläche aus einem derartigen Material. Die Einzelelemente lassen sich bei Abnutzung schnell austauschen. Das gleiche gilt für den Fall, daß die Strömungsverhältnisse der Luft im Tabakkanal geändert werden sollen, beispielsweise wenn die Fasern des zugeführten Tabaks eine andere Struktur aufweisen. ln diesem Fall werden einfach Einzelelemente mit anderen Strömungswiderständen in die Führungsnuten eingeschoben. Die Strömungsverhältnisse können leicht so eingestellt werden, daß die Luftwiderstände im Verlauf zunehmender Stranghöhe abnehmen. Außerdem ist es durch unterschiedliche Ausgestaltung der Führungsflächen der Einzelelemente leicht möglich, die Form des Strangförderbandes zu variieren von eben zu gerundeten Endbereichen bis zur ganz gerundeten teilzylindrischen Form. The invention offers the advantage that the relatively small individual elements made of highly wear-resistant Material, e.g. B. made of hard metal or ceramic, without being too expensive like an entire guide surface made of such a material. The individual elements can be quickly replaced when worn. The same applies in the event that the flow conditions the air in the tobacco channel should be changed, for example if the fibers of the supplied tobacco have a different structure. ln this case simply insert individual elements with different flow resistances into the guide grooves. The flow conditions can easily be adjusted so that the air resistance decrease in the course of increasing strand height. It is also different Design of the guide surfaces of the individual elements easily possible To vary the shape of the strand conveyor belt from flat to rounded end areas to completely rounded part-cylindrical shape.
