Description

Die Erfindung betrifft eine Vorrichtung zum Fördern eines Stranges der tabakverarbeitenden Industrie mit einer Führung für ein den Strang förderndes Band, das am Grunde eines offenen Kanals läuft. Unter einem "Strang der tabakverarbeitenden Industrie" wird insbesondere ein Faserstrang, vorzugsweise aus Schnittabak, verstanden.The invention relates to a device for conveying a strand of tobacco processing industry with a guide for a conveyor belt, that runs at the bottom of an open channel. Under a "strand of tobacco processing industry "is especially 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) is the bottom of a strand guide channel (tobacco channel), circulating strand conveyor tobacco in the form of a shower of isolated Tobacco fibers fed in a strand formation zone in the tobacco channel on the Strand conveyor accumulated and as a tobacco strand from the strand formation zone conveyed away. The tobacco rod is then reduced by excess equalized before going through in the further course of the manufacturing process Wrapping with a strip of wrapping material processed into a cigarette and finally cut into single or multiple tobacco rods. As a conveyor in modern machines, the lower strand is usually one Strand conveyor belt used, on which the accumulated fiber strand hanging is promoted. The strand conveyor belt is vacuumed from the back acted on, so that the tobacco fibers through the strand conveyor holding suction is created. This type of sponsor is also known as Suction rod. The conveyor strand of the strand conveyor extends in Tobacco canal from the beginning of the line through the area of the Surplus withdrawal facility until its end of delivery, at which the formed Strand of tobacco is delivered to a strand unit. In the strand unit, the Tobacco rod wrapped with the wrapping material strip so that a cigarette rod is formed, which is finally processed into cigarettes or filter cigarettes. 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 barrel the guide means influencing the strand conveyor.

Zigarettenstrangmaschinen mit Strangförderbändern der vorbeschriebenen Art sind beispielsweise in der US-PS 4 805 641, der GB-PS 974 821 und der US-PS 4 344 526 dargestellt.
Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine Vorrichtung der eingangs beschriebenen Art weiter zu verbessern.Cigarette rod machines with strand conveyor belts of the type described above are shown, for example, in US Pat. No. 4,805,641, GB Pat. No. 974,821 and US Pat. No. 4,344,526.
The object on which the invention is based is to further improve a device of the type described at the outset.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Führung aneinandergrenzende Einzelelemente aufweist, die in einem Halter angeordnet sind.This object is achieved in that the leadership has adjacent individual elements which are arranged in a holder.

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

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. In 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 has the advantage that the relatively small individual elements highly wear-resistant material, e.g. B. made of hard metal or ceramic, without becoming as expensive as an entire guide surface made of such a material. The individual elements can be quickly replaced when worn. The same applies the case that the flow conditions of the air in the tobacco channel are changed should, for example, if the fibers of the tobacco supplied have a different structure exhibit. In this case, individual elements are simply combined with others Flow resistances inserted into the guide grooves. The Flow conditions can easily be adjusted so that the air resistance in the Decrease course of increasing strand height. It is also different Design of the guide surfaces of the individual elements easily possible, the shape of the Belt conveyor to vary from flat to rounded end areas to the whole rounded part-cylindrical shape.
