Description

Vorrichtung zum Fördern eines Stranges der tabakverarbeitenden Industrie Device for conveying a strand of the tobacco processing industry
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 the tobacco processing industry with a guide for a belt that conveys the strand and runs at the bottom of an open channel. A “strand of the tobacco processing industry” is understood in particular to mean a fiber strand, preferably made from cut tobacco.
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 Saug- zug 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. Zigarettenstrangmaschinen mit Strangförderbändern der vorbeschriebenen Art sind bei- spielsweise 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.In a machine for producing a cigarette rod (cigarette rod machine), tobacco in the form of a shower made of individual tobacco fibers, which is the bottom of a rod guide duct (tobacco duct), is fed in the form of a shower, is collected in a rod forming zone in the tobacco duct on the rod conveyor and is conveyed out of the rod forming zone as a tobacco rod. The tobacco rod is then evened out by a decrease in excess, before it is processed into a cigarette rod in the further course of the manufacturing process by wrapping it with a strip of wrapping material and finally cut into tobacco rods of one or more lengths of use. In modern machines, the lower strand of a strand conveyor belt, on which the accumulated fiber strand is conveyed hanging, is generally used as the strand conveyor. The strand conveyor belt is subjected to negative pressure from its rear side, so that a suction draft which holds the tobacco fibers is created through the strand conveyor belt. This type of conveyor is also known as a suction line conveyor. The conveying strand of the strand conveyor belt extends in the tobacco channel from the beginning of the strand formation zone through the area of the excess removal device to its end of delivery, at which the tobacco strand formed is delivered to a strand unit. The tobacco rod is wrapped with the wrapping material strip in the rod unit, so that a rod of cigarettes is formed which is finally processed into cigarettes or filter cigarettes. The length of the conveyor section of the suction strand conveyor and the high speed of modern strand machines place high demands on the strand conveyor and the guiding means influencing the running of the strand conveyor. 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 in the introduction.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Führung aneinandergren- zende Einzelelemente aufweist, die in einem Halter angeordnet sind.This object is achieved in that the guide has adjoining 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 can be found in 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 made of highly wear-resistant material, for. 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 in the event that the flow conditions of the air in the tobacco channel are to be changed, for example if the fibers of the tobacco supplied have a different structure. In this case, individual elements with different flow resistances are simply inserted into the guide grooves. The flow conditions can easily be adjusted so that the air resistance decreases as the height of the strand increases. In addition, it is easily possible by varying the design of the guide surfaces of the individual elements to vary the shape of the strand conveyor belt from flat to rounded end regions to the completely rounded partially cylindrical shape.

Die Figuren 1 und 2 zeigen einen Teil einer Strangführungseiπheit 1 einer Zigaret- tenstrangmaschine in vergrößertem Maßstab, die zur besseren Darstellbarkeit durch Bruchlinien stark verkürzt ist. Ein in Figur 1 von unten dargestellter Halter weist Luftdurchlässe 2 auf, durch die Saugluft von unten nach oben in einen Unterdruckraum (Position 3 in den Figuren 3 und 4) strömen kann.FIGS. 1 and 2 show part of a strand guide unit 1 of a cigarette rod machine on an enlarged scale, which is greatly shortened by broken lines for better representation. A holder shown in FIG. 1 from below has air passages 2 through which suction air can flow from bottom to top into a vacuum chamber (position 3 in FIGS. 3 and 4).
In den Figuren 3 und 4 sind weitere Einzelheiten zeigende Schnitte entsprechend den Schnittlinien A-A bzw. B-B in Figur 2 dargestellt. In diese Schnitte sind zusätzlich Einzelelemente 4 zur Führung eines Strangförderbandes 6 (übertrieben dick gezeichnet) und ein Tabakkanal 7 eingezeichnet. Der Halter 1 weist zwei Wangen 8 und 9 auf, die mittels nicht sichtbarer Schrauben miteinander verschraubt werden können. In Figur 2 ist eine entsprechende Gewindebohrung 11 dargestellt. Die Wangen 8 und 9 haben Führungsnuten 12, in die segmentförmige Einzelelemente 4 zur Bandführung, von denen Figur 5 Einzelheiten zeigt, senkrecht zur Zeichenebene einschiebbar sind. Zur klemmenden Fixierung der Ein- zelelemente/Segmente 4 können nicht dargestellte Stiftschrauben in Gewindebohrungen 13 dienen. Im Mittenbereich haben die Einzelelemente 4 Luftdurchlässe 5, welche unterschiedliche Strömungsquerschnitte aufweisen können. Die Einzelelemente 4 begrenzen und führen mit oben und seitlich angeordneten Führungsflächen das luftdurchlässige Förderband 6, das in Richtung senkrecht zur Zeichenebene antreibbar ist. Unterhalb der Wan- gen 8 und 9 und der Einzelelemente 4 erstrecken sich in bekannter Weise Wangen 14 und 16, die den Tabakkanal 7 begrenzen. Die von unten zugeführten Tabakfasern werden von einem Saugluftstrom, der durch den Kanal 7, das luftdurchlässige Band 6, die Luftdurchlässe 5 in den Einzelelementen 4 sowie durch die Luftdurchlässe 2 in dem Halter 1 in den Unterdruckraum 3 strömt, mitgenommen und lagern sich an dem Band 6 an, wo sie sich zu einem nicht dargestellten Tabakstrang ansammeln und abgefördert werden.FIGS. 3 and 4 show further details of sections corresponding to section lines A-A and B-B in FIG. 2. In these cuts, individual elements 4 for guiding a strand conveyor belt 6 (drawn excessively thick) and a tobacco channel 7 are also shown. The holder 1 has two cheeks 8 and 9 which can be screwed together by means of invisible screws. A corresponding threaded bore 11 is shown in FIG. The cheeks 8 and 9 have guide grooves 12 into which segment-shaped individual elements 4 for tape guidance, of which FIG. 5 shows details, can be inserted perpendicular to the plane of the drawing. Studs (not shown) in threaded bores 13 can serve for the clamping fixation of the individual elements / segments 4. In the central area, the individual elements 4 have air outlets 5, which can have different flow cross sections. The individual elements 4 limit and guide the air-permeable conveyor belt 6 with guide surfaces arranged at the top and on the side, which can be driven in the direction perpendicular to the plane of the drawing. Beneath the cheeks 8 and 9 and the individual elements 4, cheeks 14 and 16, which delimit the tobacco channel 7, extend in a known manner. The tobacco fibers fed from below are taken along by a suction air flow that flows through the channel 7, the air-permeable band 6, the air passages 5 in the individual elements 4 and through the air passages 2 in the holder 1 into the vacuum chamber 3 and are stored on the band 6 to where they accumulate and are transported to a tobacco rod, not shown.
Figur 4 unterscheidet sich von Figur 3 nur dadurch, daß die Gewindebohrungen 13 zum Klemmen der Einzelelemente 4 fehlen.Figure 4 differs from Figure 3 only in that the threaded holes 13 for clamping the individual elements 4 are missing.
Figur 5 zeigt eine Draufsicht auf die Führungsseite eines Einzelelementes 4. Die in denFigure 5 shows a plan view of the guide side of an individual element 4. Die in the
Führungennuten 12 der Wangen 8, 9 eingeschobenen Flächen der Einzelelemente 4 wer- den von den Linien 18, 19 begrenzt. Von den Linien 19 und 21 wird ein Steg 22 begrenzt. Zwischen den Stegen 22 ist das Strangförderband 6 an Führungsflächen 24 geführt. Mit 23 sind leichte Abschrägungen nach unten bezeichnet. Die gegenüberliegende Rückseite des Einzelelementes 4 ist glatt.Guide grooves 12 of the cheeks 8, 9 inserted surfaces of the individual elements 4 are bounded by lines 18, 19. A web 22 is delimited by lines 19 and 21. The strand conveyor belt 6 is guided on guide surfaces 24 between the webs 22. With 23 slight bevels are designated below. The opposite back of the individual element 4 is smooth.
Anhand der Figuren 1 bis 5 lassen sich die in der Einleitung erwähnten Vorteile leicht erkennen: Leichtes Anbringen der relativ kurzen Einzelelemente, die auch dann preisgünstig sind, wenn sie aus relativ teurem verschleißfestem Material bestehen; leichtes Auswechseln der Einzelelemente, z. B. wegen Verschleißes oder zur Beeinflussung der Strömungs- Verhältnisse der Saugluft im Tabakkanal 7.The advantages mentioned in the introduction can be easily recognized on the basis of FIGS. 1 to 5: easy attachment of the relatively short individual elements, which are also inexpensive if they consist of relatively expensive wear-resistant material; easy replacement of the individual elements, e.g. B. due to wear or to influence the flow conditions of the suction air in the tobacco duct 7.
Durch den Einsatz spezifisch gestalteter Einzelelemente 4 mit in Form und Größe unterschiedlichen Strömungsquerschnitten ihrer Luftdurchlässe 5 läßt sich durch entsprechende Kombination oder Auswechslung von Einzelelementen ein gewünschtes bzw. optimales Strömungsprofil über die Länge des Strangführungskanals erzielen.Through the use of specifically designed individual elements 4 with different flow cross sections in shape and size of their air passages 5, a desired or optimal flow profile can be achieved over the length of the strand guide channel by appropriate combination or replacement of individual elements.
Figur 6 zeigt eine Variante eines geschnitten gezeichneten Einzelelementes 4 mit einer Führungsfläche 24 für das Strangförderband 6, deren Endbereiche 24a gerundet sind in vergrößertem Maßstab.FIG. 6 shows a variant of a single element 4 shown in section with a guide surface 24 for the strand conveyor 6, the end regions 24a of which are rounded on an enlarged scale.
