Gelöst wird diese Aufgabe durch ein Verfahren zum Herstellen von stabförmigen Rauchprodukten, vorzugsweise an einer Trommelmaschine der Tabak verarbeitenden Industrie oder Filteransetzmaschine, wobei stabförmige Artikel der Tabak verarbeitenden Industrie in Aufnahmemulden von rotierenden Fördertrommeln einer Förderanordnung zum Fördern von stabförmigen Artikeln queraxial hintereinander angeordnet werden oder sind und durch die Rotation der Fördertrommeln in queraxialer Richtung gefördert werden und wobei die stabförmigen Artikel im jeweiligen Übergabebereich zwischen zwei Fördertrommeln von jeweils einer Artikel abgebenden Fördertrommel an eine Artikel aufnehmende Fördertrommel übergeben werden, wobei die Förderanordnung einen ersten Förderabschnitt mit einer ersten Schneidtrommel und einer an der ersten Schneidtrommel angeordneten ersten Schneideinrichtung zum Schneiden von stabförmigen Artikeln und einen zweiten Förderabschnitt mit einer zweiten Schneidtrommel und einer an der zweiten Schneidtrommel angeordneten zweiten Schneideinrichtung zum Schneiden von stabförmigen Artikeln aufweist, wobei auf der ersten Schneidtrommel des ersten Förderabschnitts stabförmige Artikel mehrfacher Gebrauchslänge jeweils in stabförmige Artikelstäbe geschnitten werden und nachfolgend auf der zweiten Schneidtrommel des zweiten Förderabschnitts die stabförmigen Artikelstäbe jeweils in Artikelstabstücke geschnitten werden, wobei bezogen auf die queraxiale Förderrichtung der stabförmigen Artikel nach der ersten Schneidtrommel des ersten Förderabschnitts und der zweiten Schneidtrommel des zweiten Förderabschnitts eine Zuführeinrichtung zum Zuführen von Rauchartikelkomponenten zu den auf den Fördertrommeln geförderten stabförmigen Artikeln vorgesehen ist, wobei im ersten Förderabschnitt die stabförmigen Artikel auf der ersten Schneidtrommel mit einem ersten vorbestimmten Teilungsabstand zwischen den Aufnahmemulden der ersten Schneidtrommel gefördert werden und wobei im zweiten Förderabschnitt die stabförmigen Artikel auf der zweiten Schneidtrommel mit einem zweiten vorbestimmten Teilungsabstand zwischen den Aufnahmemulden der zweiten Schneidtrommel gefördert werden und wobei der erste vorbestimmte Teilungsabstand der ersten Schneidtrommel des ersten Förderabschnitts gleich oder größer als der zweite vorbestimmte Teilungsabstand der zweiten Schneidtrommel des zweiten Förderabschnitts ist.This object is achieved by a method for producing rod-shaped smoking products, preferably on a drum machine in the tobacco processing industry or filter attachment machine, with rod-shaped articles from the tobacco processing industry being or being arranged transversely one behind the other in receiving troughs of rotating conveyor drums of a conveyor arrangement for conveying rod-shaped articles and are conveyed by the rotation of the conveyor drums in the transverse axial direction and the rod-shaped articles are transferred in the respective transfer area between two conveyor drums from a conveyor drum delivering articles to a conveyor drum receiving articles, the conveyor arrangement having a first conveyor section with a first cutting drum and a first cutting device arranged on the first cutting drum for cutting rod-shaped articles, and a second conveyor section with a second cutting drum and a second cutting device arranged on the second cutting drum for cutting rod-shaped articles, with the first cutting drum of the first conveyor section Rod-shaped articles of multiple usage length are each cut into rod-shaped article rods and then the rod-shaped article rods are each cut into article rod pieces on the second cutting drum of the second conveyor section, with the rod-shaped articles being downstream of the first cutting drum of the first conveyor section and the second cutting drum of the second in relation to the transverse-axial conveying direction Conveying section is provided a feeding device for feeding smoking article components to the rod-shaped articles conveyed on the conveyor drums t, wherein in the first conveying section the rod-shaped articles are conveyed on the first cutting drum with a first predetermined pitch between the receiving troughs of the first cutting drum and wherein in the second conveying section the rod-shaped articles are conveyed on the second cutting drum with a second predetermined pitch between the receiving troughs of the second cutting drum and wherein the first predetermined pitch of the first cutting drum of the first conveyor section is equal to or greater than the second predetermined pitch of the second cutting drum of the second conveyor section.

Die Erfindung beruht auf dem Gedanken, dass an einer Trommelmaschine zur Herstellung von stabförmigen Rauchprodukten beispielsweise von einer Strangmaschine mehrfach lange Artikelstäbe als Produkte der Strangmaschine an die Trommelmaschine, insbesondere Filteransetzmaschine, übernommen werden, wobei in einem ersten Förderabschnitt eine erste Schneidtrommel vorgesehen ist, um die Artikelstäbe, insbesondere mehrfach lange Tabakstöcke, in entsprechende stabförmige Artikelstäbe zu schneiden, wobei anschließend die stabförmigen Artikelstäbe zu einer zweiten Schneidtrommel mit einer Schneideinrichtung, die im zweiten Förderabschnitt der Trommelmaschine angeordnet ist, gefördert werden. Hierbei kann im ersten Förderabschnitt, bezogen auf die Förderrichtung der stabförmigen Produkte stromaufwärts vor der ersten Schneidtrommel eine Übernahmetrommel angeordnet sein, um von einer Strangmaschine die mehrfach langen Produkte zu übernehmen und zu der ersten Schneidtrommel im ersten Förderabschnitt zu fördern. Hierbei weist die Übernahmetrommel im ersten Förderabschnitt denselben Teilungsabstand von Aufnahmemulden auf wie die Aufnahmemulden der ersten Schneidtrommel. Anschließend werden die stabförmigen Artikelstäbe von der ersten Schneidtrommel an weitere Fördertrommeln, wie zum Beispiel Staffeltrommeln, Schiebetrommeln, Transfertrommeln, Spreiztrommeln oder dergleichen, übergeben.The invention is based on the idea that on a drum machine for the production of rod-shaped smoking products, for example, from a rod machine, multiple long article rods are taken over as products from the rod machine to the drum machine, in particular a filter attachment machine, with a first conveyor section first cutting drum is provided in order to cut the article rods, in particular multi-length tobacco rods, into corresponding rod-shaped article rods, the rod-shaped article rods then being conveyed to a second cutting drum with a cutting device which is arranged in the second conveyor section of the drum machine. A transfer drum can be arranged in the first conveyor section, based on the conveying direction of the rod-shaped products upstream of the first cutting drum, in order to take over the multiple-length products from a strand machine and convey them to the first cutting drum in the first conveyor section. In this case, the take-over drum in the first conveyor section has the same pitch of receiving troughs as the receiving troughs of the first cutting drum. The rod-shaped article rods are then transferred from the first cutting drum to further conveyor drums, such as staggered drums, pushing drums, transfer drums, spreading drums or the like.

Gemäß der Erfindung wird eine produktschonende Verarbeitung bzw. Bearbeitung der stabförmigen Produkte dadurch erreicht, dass der Teilungsabstand der Aufnahmemulden sowohl der ersten Schneidtrommel im ersten Förderabschnitt als auch der Teilungsabstand der Aufnahmemulden der zweiten Schneidtrommel im zweiten Förderabschnitt gleich sind oder dass der Teilungsabstand der Aufnahmemulden der zweiten Schneidtrommel kleiner ist als der Teilungsabstand der Aufnahmemulden der ersten Schneidtrommel im ersten Förderabschnitt.According to the invention, a product-friendly processing or processing of the stick-shaped products is achieved in that the pitch of the receiving troughs of both the first cutting drum in the first conveyor section and the pitch of the receiving troughs of the second cutting drum in the second conveyor section are the same or that the pitch of the receiving troughs of the second cutting drum is smaller than the pitch of the receiving troughs of the first Cutting drum in the first conveyor section.

Unter Teilungsabstand wird bei Fördertrommeln der queraxiale Abstand der Aufnahmemulden verstanden, in denen die Rauchartikelgruppen angeordnet oder transportiert werden. Der (queraxiale) Abstand wird dabei vom Muldenmittelpunkt der Aufnahmemulde zum darauffolgenden Muldenmittelpunkt der benachbarten Aufnahmemulde des auf der Oberfläche die stabförmigen Rauchartikel(gruppen) transportierenden Muldenförderers oder von Muldengrund zu Muldengrund bei z.B. einer prismenförmigen Aufnahmemulde gemessen. Der Teilungsabstand bei einem Trommelförderer, auch als Fördertrommel bezeichnet, ist der queraxiale Abstand bzw. die Länge des (Kreis-)Bogens zwischen (benachbarten) Muldenmittelpunkten auf der Kreislinie, auf der die Muldenmittelpunkte bzw. Muldenmittelpunktsachsen der Mulden angeordnet sind.In the case of conveyor drums, the pitch distance is understood to mean the transverse axial distance between the receiving troughs in which the groups of smoking articles are arranged or transported. The (transverse axial) distance is measured from the trough center of the receiving trough to the subsequent trough center of the adjacent receiving trough of the trough conveyor transporting the rod-shaped smoking articles (groups) on the surface or from trough base to trough base in the case of a prism-shaped receiving trough, for example. The pitch in a drum conveyor, also referred to as a conveyor drum, is the transverse axial distance or the length of the (circular) arc between (adjacent) trough centers on the circular line on which the trough centers or trough center axes of the troughs are arranged.

Weisen alle Fördertrommeln des ersten und des zweiten Förderabschnitts, und damit auch die erste Schneidtrommel des ersten Förderabschnitts und die zweite Schneidtrommel des zweiten Förderabschnitts, jeweils den gleichen Teilungsabstand auf, so endet der erste Förderabschnitt zwischen der ersten Schneidtrommel und der Fördertrommel, an die von der ersten Schneidtrommel die geschnittenen stabförmigen Artikelstäbe übergeben werden. Der zweite Förderabschnitt beginnt ab der nach der ersten Schneidtrommel des ersten Förderabschnitts angeordneten Fördertrommel, an die die stabförmigen Artikelstäbe übergeben werden.If all conveyor drums of the first and second conveyor section, and thus also the first cutting drum of the first conveyor section and the second cutting drum of the second conveyor section, each have the same pitch, the first conveyor section ends between the first cutting drum and the conveyor drum to which the the cut rod-shaped article rods are transferred to the first cutting drum. The second conveyor section starts from the conveyor drum arranged after the first cutting drum of the first conveyor section, to which the rod-shaped article rods are transferred.

Haben die Fördertrommeln des zweiten Förderabschnitts einen geringeren Teilungsabstand als die Fördertrommeln des ersten Förderabschnitts, so beginnt der zweite Förderabschnitt mit der Fördertrommel, die einen geringeren Teilungsabstand zwischen den Aufnahmemulden aufweist als die vorangehende Fördertrommel des ersten Förderabschnitts mit dem größeren Teilungsabstand.If the conveyor drums of the second conveyor section have a smaller spacing than the conveyor drums of the first conveyor section, the second conveyor section begins with the conveyor drum, which has a smaller pitch between the receiving troughs than the preceding conveyor drum of the first conveyor section with the larger pitch.

Dadurch, dass beispielsweise die stabförmigen Produkte im zweiten Förderabschnitt auf Fördertrommeln mit einem geringeren Teilungsabstand als auf den Fördertrommeln des ersten Förderabschnitts gefördert werden, werden diese stabförmigen Produkte in ihrer Bahngeschwindigkeit reduziert, wodurch die stabförmigen Produkte produktschonend an der Trommelmaschine gefördert und geschnitten werden.Because, for example, the rod-shaped products in the second conveyor section are conveyed on conveyor drums with a smaller pitch than on the conveyor drums of the first conveyor section, these rod-shaped products are reduced in their web speed, which means that the rod-shaped products are conveyed and cut gently on the drum machine.

Erst nach der zweiten Schneidtrommel, bezogen auf die Förderrichtung der stabförmigen Produkte an der Trommelmaschine, werden über eine Zuführeinrichtung stabförmige Segmente oder Artikelsegmente, wie zum Beispiel Filtersegmente, an die geschnittenen Produkte angelegt, so dass daraus Artikelgruppen gebildet werden, die anschließend zum Beispiel mit einem Umhüllungsmaterialstreifen umhüllt und geschnitten werden. Dabei kann es vorgesehen sein, dass zwischen zwei längsaxial beabstandete Artikelstabstücke auf einer Zusammenstelltrommel entsprechende Filtersegmente oder andere Rauchartikelsegmente eingelegt werden und diese anschließend mittels eines Materialstreifens umhüllt werden, so dass nachfolgend durch einen mittigen Schnitt durch die gebildete Rauchartikelgruppe stabförmige Rauchprodukte einfacher Gebrauchslänge entstehen, die anschließend weiterverarbeitet werden. Dadurch ist es möglich, auch kurze stabförmige Produkte, wie zum Beispiel Heat-Not-Burn-Produkte, mit beispielsweise einer Produktlänge von 40 bis 65 mm an einer Trommelmaschine bzw. Filteransetzmaschine herzustellen.Only after the second cutting drum, in relation to the conveying direction of the rod-shaped products on the drum machine, are rod-shaped segments or article segments, such as filter segments, applied to the cut products via a feed device, so that article groups are formed from them, which are then, for example, Wrapping material strips are wrapped and cut. Provision can be made for corresponding filter segments or other smoking article segments to be inserted between two lengthwise-axially spaced article rod pieces on an assembly drum and for these to then be wrapped by means of a strip of material, so that a central cut through the group of smoking articles formed results in rod-shaped smoking products of a simple usable length which are then be further processed. This makes it possible to also produce short rod-shaped products, such as heat-not-burn products, with a product length of 40 to 65 mm, for example, on a drum machine or filter attachment machine.

Dazu ist in einer Weiterbildung des Verfahrens vorgesehen, dass der erste Förderabschnitt eine weitere Fördertrommel oder mehrere Fördertrommeln aufweist, wobei der Teilungsabstand der Aufnahmemulden der weiteren Fördertrommel oder die Teilungsabstände der Aufnahmemulden der Fördertrommeln des ersten Förderabschnitts dem ersten Teilungsabstand der ersten Schneidtrommel des ersten Förderabschnitts entsprechen. Dadurch haben alle Fördertrommeln des ersten Förderabschnitts jeweils den gleichen Teilungsabstand. Insbesondere ist eine Fördertrommel des ersten Förderabschnitts als Übernahmetrommel ausgebildet, wodurch stabförmige Produkte beispielsweise von einer Strangmaschine übernommen werden und anschließend zur ersten Schneidtrommel des ersten Förderabschnitts gefördert werden.For this purpose, in a further development of the method, it is provided that the first conveyor section has a further conveyor drum or a plurality of conveyor drums, the spacing of the receiving troughs of the further conveyor drum or the spacing of the receiving troughs of the conveyor drums of the first conveyor section correspond to the first pitch of the first cutting drum of the first conveyor section. As a result, all conveyor drums of the first conveyor section each have the same pitch. In particular, a conveyor drum of the first conveyor section is designed as a transfer drum, whereby rod-shaped products are taken over, for example, from a strand machine and then conveyed to the first cutting drum of the first conveyor section.

Darüber hinaus ist in einer Ausführungsform des Verfahrens vorgesehen, dass der zweite Förderabschnitt eine weitere Fördertrommel oder mehrere Fördertrommeln aufweist, wobei der Teilungsabstand der Aufnahmemulden der weiteren Fördertrommel oder die Teilungsabstände der Aufnahmemulden der Fördertrommeln des zweiten Förderabschnitts dem zweiten Teilungsabstand der zweiten Schneidtrommel des zweiten Förderabschnitts entsprechen. Hierbei kann der zweite Förderabschnitt eine Staffeltrommel, eine Transfertrommel, eine Schiebetrommel sowie eine Spreiztrommel usw. umfassen, wobei die Trommeln, bezogen auf die Förderrichtung der stabförmigen Produkte, vor, d.h. stromaufwärts, oder nach der zweiten Schneidtrommel, d.h. stromabwärts, angeordnet sein können.In addition, one embodiment of the method provides that the second conveyor section has a further conveyor drum or a plurality of conveyor drums, with the pitch of the receiving troughs of the further conveyor drum or the pitch of the receiving troughs of the conveyor drums of the second conveyor section corresponding to the second pitch of the second cutting drum of the second conveyor section . The second conveyor section can include a staggered drum, a transfer drum, a shift drum and a spreading drum, etc., with the drums being able to be arranged before, i.e. upstream, or after the second cutting drum, i.e. downstream, in relation to the conveying direction of the stick-shaped products.

Gemäß der Erfindung ist vorgesehen, dass auf der ersten Schneidtrommel des ersten Förderabschnitts stabförmige Artikel mehrfacher Gebrauchslänge jeweils in stabförmige Artikelstäbe geschnitten werden und nachfolgend auf der zweiten Schneidtrommel des zweiten Förderabschnitts die stabförmigen Artikelstäbe jeweils in Artikelstabstücke geschnitten werden. Die Länge der Artikelstabstücke beträgt beispielsweise zwischen 10 bis 38 mm.According to the invention, it is provided that on the first cutting drum of the first conveyor section rod-shaped articles of multiple usage lengths are each cut into rod-shaped article rods and then on the second cutting drum of the second conveyor section the rod-shaped article rods are each cut into article rod pieces. The length of the article rod pieces is, for example, between 10 and 38 mm.

Beispielsweise ist es im Rahmen der Erfindung möglich, dass von einer Strangmaschine stabförmige Artikel mehrfacher Gebrauchslänge übernommen werden und mittels der ersten Schneidtrommel und der Schneideinrichtung in zwei oder drei gleich lange stabförmige Artikelstäbe mittels der Schneideinrichtung an der ersten Schneidtrommel im ersten Förderabschnitt geschnitten werden, die anschließend an eine Staffeltrommel mit einem geringeren Teilungsabstand als die Fördertrommeln des ersten Förderabschnitts übergeben werden, so dass anschließend die übernommenen stabförmigen Artikelstäbe auf der Staffeltrommel gestaffelt werden und anschließend an eine Schiebetrommel übergeben werden. Auf der Schiebetrommel wird eine Reihe von queraxial hintereinander angeordneten stabförmigen Artikelstäben gebildet, die nachfolgend an die zweite Schneidtrommel des zweiten Förderabschnitts übergeben werden, um die stabförmigen Artikelstäbe in Artikelstabstücke auf der Schneidtrommel zu schneiden. Anschließend werden auf einer nachfolgenden Spreiztrommel des zweiten Förderabschnitts die geschnittenen stabförmigen Artikelstäbe längsaxial voneinander beabstandet, so dass nachfolgend mittels einer Zuführeinrichtung ein oder mehrere Artikelstabsegmente, wie zum Beispiel Filtersegmente, zwischen die längsaxial beabstandeten Artikelstabstücke eingelegt werden, wodurch Rauchartikelgruppen doppelter Gebrauchslänge gebildet werden, die anschließend mittels eines Umhüllungsmaterialstreifens umhüllt werden. Die umhüllten Rauchartikelgruppen doppelter Gebrauchslänge werden anschließend durch einen mittigen Schnitt in Rauchartikelgruppen einfacher Gebrauchslänge als stabförmige Rauchprodukte geschnitten.For example, it is possible within the scope of the invention for rod-shaped articles of multiple useful lengths to be taken over from a strand machine and by means of the first cutting drum and the cutting device into two or three rod-shaped article sticks of equal length by means of the cutting device on the first cutting drum in the first conveyor section, which are then transferred to a staggering drum with a smaller pitch than the conveyor drums of the first conveyor section, so that the bar-shaped article sticks taken over are then staggered on the staggering drum and then transferred to a sliding drum. A series of cross-axially arranged rod-shaped article rods arranged one behind the other is formed on the pushing drum and are subsequently transferred to the second cutting drum of the second conveyor section in order to cut the rod-shaped article rods into article rod pieces on the cutting drum. The cut rod-shaped article rods are then longitudinally and axially spaced from one another on a subsequent spreading drum of the second conveyor section, so that one or more article rod segments, such as filter segments, are then inserted between the longitudinally and axially spaced article rod pieces by means of a feed device, whereby smoking article groups with double the useful length are formed, which are then covered by a strip of wrapping material. The wrapped double use length smoking article groups are then cut through a center cut into single use length smoking article groups as rod-shaped smoking products.

Ferner zeichnet sich das Verfahren dadurch aus, dass nach dem Schneiden der Artikelstäbe jeweils in Artikelstabstücke durch die zweite Schneidtrommel des zweiten Förderabschnitts an die jeweiligen Artikelstabstücke auf wenigstens einer Zusammenstelltrommel durch die Zuführeinrichtung eine oder mehrere stabförmige Rauchartikelkomponenten, insbesondere Artikelsegmente oder Filtersegmente, in längsaxialer Richtung der Artikelstabstücke angefügt werden, so dass stabförmige Rauchartikelgruppen, insbesondere einfacher oder mehrfacher Länge, gebildet werden.Furthermore, the method is characterized in that after the article sticks have been cut into article stick pieces by the second cutting drum of the second conveyor section, one or more stick-shaped smoking article components, in particular article segments or filter segments, are attached to the respective article stick pieces on at least one assembly drum by the feed device in the longitudinal axial direction of the Article rod pieces are added so that rod-shaped smoking article groups, in particular single or multiple lengths, are formed.

Dazu ist vorteilhafterweise weiter vorgesehen, dass nach der Bildung von stabförmigen Rauchartikelgruppen aus Artikelstabstücken und stabförmigen Rauchartikelkomponenten die stabförmigen Rauchartikelgruppen von wenigstens einem Materialstreifen, insbesondere Umhüllungsmaterialstreifen, jeweils wenigstens teilweise umhüllt werden.This is advantageously further provided that after the formation of Rod-shaped smoking article groups made up of article rod pieces and rod-shaped smoking article components, the rod-shaped smoking article groups being at least partially encased by at least one strip of material, in particular strip of wrapping material.

Insbesondere werden nach der Bildung von stabförmigen Rauchartikelgruppen mehrfacher Länge die stabförmigen Rauchartikelgruppen jeweils mittels einer weiteren Schneideinrichtung geschnitten. Insbesondere werden hierbei stabförmige Rauchartikelgruppen einfacher Gebrauchslänge als stabförmige Rauchprodukte hergestellt.In particular, after the formation of rod-shaped smoking article groups of multiple lengths, the rod-shaped smoking article groups are each cut by means of a further cutting device. In particular, rod-shaped smoking article groups with a simple use length are produced as rod-shaped smoking products.

Ferner wird die Aufgabe gelöst durch eine Förderanordnung einer Trommelmaschine der Tabak verarbeitenden Industrie, insbesondere Filteransetzmaschine, zum Herstellen von stabförmigen Rauchprodukten mit mehreren Fördertrommeln wobei stabförmige Artikel der Tabak verarbeitenden Industrie in Aufnahmemulden von rotierenden Fördertrommeln queraxial hintereinander angeordnet werden oder sind und durch die Rotation der Fördertrommeln in queraxialer Richtung gefördert werden und wobei die stabförmigen Artikel im jeweiligen Übergabebereich zwischen zwei Fördertrommeln von jeweils einer Artikel abgebenden Fördertrommel an eine Artikel aufnehmende Fördertrommel übergeben werden, wobei die Förderanordnung einen ersten Förderabschnitt mit einer ersten Schneidtrommel und einer an der ersten Schneidtrommel angeordneten ersten Schneideinrichtung zum Schneiden von stabförmigen Artikeln und einen zweiten Förderabschnitt mit einer zweiten Schneidtrommel und einer an der zweiten Schneidtrommel angeordneten zweiten Schneideinrichtung zum Schneiden von stabförmigen Artikeln aufweist, wobei auf der ersten Schneidtrommel des ersten Förderabschnitts stabförmige Artikel mehrfacher Gebrauchslänge jeweils in stabförmige Artikelstäbe geschnitten werden und nachfolgend auf der zweiten Schneidtrommel des zweiten Förderabschnitts die stabförmigen Artikelstäbe jeweils in Artikelstabstücke geschnitten werden, wobei bezogen auf die queraxiale Förderrichtung der stabförmigen Artikel nach der ersten Schneidtrommel und der zweiten Schneidtrommel eine Zuführeinrichtung zum Zuführen von Rauchartikelkomponenten zu den auf den Fördertrommeln geförderten stabförmigen Artikeln vorgesehen ist, wobei im ersten Förderabschnitt die stabförmigen Artikel auf der ersten Schneidtrommel mit einem ersten vorbestimmten Teilungsabstand zwischen den Aufnahmemulden der ersten Schneidtrommel gefördert werden oder förderbar sind und wobei im zweiten Förderabschnitt die stabförmigen Artikel auf der zweiten Schneidtrommel mit einem zweiten vorbestimmten Teilungsabstand zwischen den Aufnahmemulden der zweiten Schneidtrommel gefördert werden oder förderbar sind und wobei der erste vorbestimmte Teilungsabstand der ersten Schneidtrommel des ersten Förderabschnitts gleich oder größer als der zweite vorbestimmte Teilungsabstand der zweiten Schneidtrommel des zweiten Förderabschnitts ist.Furthermore, the object is achieved by a conveyor arrangement of a drum machine in the tobacco processing industry, in particular a filter attachment machine, for the production of rod-shaped smoking products with several conveyor drums, with rod-shaped articles from the tobacco processing industry being or being arranged transversely one behind the other in receiving troughs of rotating conveyor drums and by the rotation of the conveyor drums are conveyed in a transverse axial direction and wherein the rod-shaped articles are transferred in the respective transfer area between two conveyor drums from a conveyor drum delivering articles to a conveyor drum receiving articles, wherein the conveyor arrangement has a first conveyor section with a first cutting drum and a first cutting device arranged on the first cutting drum for cutting of stick-shaped articles and a second conveyor section with a second cutting drum and one arranged on the second cutting drum n second cutting device for cutting rod-shaped articles, wherein rod-shaped articles of multiple usage lengths are each cut into rod-shaped article rods on the first cutting drum of the first conveyor section, and the rod-shaped article rods are then each cut into article rod pieces on the second cutting drum of the second conveyor section, wherein based on the cross-axial conveying direction of the rod-shaped articles after the first cutting drum and the second Cutting drum is provided with a feed device for feeding smoking article components to the rod-shaped articles conveyed on the conveyor drums, wherein in the first conveying section the rod-shaped articles are conveyed or can be conveyed on the first cutting drum with a first predetermined spacing between the receiving troughs of the first cutting drum and wherein in the second conveying section the rod-shaped articles are conveyed or can be conveyed on the second cutting drum with a second predetermined pitch between the receiving troughs of the second cutting drum and wherein the first predetermined pitch of the first cutting drum of the first conveyor section is equal to or greater than the second predetermined pitch of the second cutting drum of the second conveyor section .

Die Filteransetzmaschine F weist eine Übernahmetrommel 12 auf, mittels der beispielsweise Tabakstockstäbe 100 (vgl. Fig. 2) mehrfacher Gebrauchslänge von einer (hier nicht dargestellten) Strangmaschine übernommen werden und von der Übernahmetrommel 12 an eine nachfolgende Schneidtrommel 14 übergeben werden. An der Schneidtrommel 14 ist eine Schneideinrichtung 16 in Form von mehreren Messern vorgesehen, um die mehrfach langen Tabakstockstäbe 100 (vgl. Fig. 2) in stabförmige Artikelstäbe bzw. Tabakstöcke zu schneiden. Die Schneideinrichtung 16 kann hierbei ein oder mehrere Schneidmesser aufweisen. Bei der in Fig. 1 und 2 gezeigten Schneideinrichtung 16 sind zwei Schneidmesser vorgesehen, um die Tabakstockstäbe 100 in drei gleich lange Tabakstöcke 111, 112, 113 zu schneiden.The filter attachment machine F has a transfer drum 12, by means of which, for example, tobacco rods 100 (cf. 2 ) of multiple useful lengths are taken over by a strand machine (not shown here) and transferred from the transfer drum 12 to a subsequent cutting drum 14 . A cutting device 16 in the form of several knives is provided on the cutting drum 14 in order to cut the tobacco rods 100 (cf. 2 ) into rod-shaped article rods or tobacco rods. The cutting device 16 can have one or more cutting knives. At the in 1 and 2 In the cutting device 16 shown, two cutting knives are provided in order to cut the tobacco rods 100 into three tobacco rods 111, 112, 113 of equal length.

Die Schneidtrommel 14 und die stromauf an der Schneidtrommel 14 angeordnete Übernahmetrommel 12 sind als Fördertrommeln für den queraxialen Transport von stabförmigen Artikeln der Tabak verarbeitenden Industrie mit Aufnahmemulden ausgebildet, wobei die Schneidtrommel 14 und die Übernahmetrommel 12 in Umfangsrichtung jeweils denselben und gleichen queraxialen Teilungsabstand zwischen den regelmäßig angeordneten Aufnahmemulden aufweisen. Die Schneidtrommel 14 und die Übernahmetrommel 12 sind in einem ersten Förderabschnitt A1 der Filteransetzmaschine F angeordnet, wobei der Teilungsabstand der Aufnahmemulden der (ersten) Schneidtrommel 14 dem Teilungsabstand der anderen Fördertrommeln, wie z.B. der Übernahmetrommel 12, entspricht.The cutting drum 14 and the transfer drum 12 arranged upstream of the cutting drum 14 are designed as conveyor drums for the transverse axial transport of rod-shaped articles in the tobacco processing industry with receiving troughs, with the cutting drum 14 and the transfer drum 12 each having the same transverse axial spacing in the circumferential direction between the regularly have arranged receiving troughs. The cutting drum 14 and the transfer drum 12 are arranged in a first conveyor section A1 of the filter tipping machine F, with the pitch of the receiving troughs of the (first) cutting drum 14 corresponding to the pitch of the other conveyor drums, such as the transfer drum 12 .

Gemäß dem in Fig. 2 dargestellten Verfahrensablauf werden aus Tabakstockstäben 100 sechsfacher Gebrauchslänge, die von einer Strangmaschine hergestellt wurden und an die Filteransetzmaschine F übergeben wurden, drei Tabakstöcke 111, 112, 113 doppelter Gebrauchslänge auf der Schneidtrommel 14 geschnitten.According to the 2 In the process sequence shown, three tobacco rods 111, 112, 113 of twice the useful length are cut on the cutting drum 14 from tobacco rods 100 of six times the useful length, which were produced by a rod machine and transferred to the filter attachment machine F.

Anschließend werden die geschnittenen Tabakstöcke doppelter Länge 111, 112, 113 an die Aufnahmemulden einer nachfolgenden Staffeltrommel 22 eines zweiten Förderabschnitts A2 übergeben. Auf der Staffeltrommel 22 werden die geschnittenen Tabakstöcke 111, 112, 113 in gestaffelter Weise queraxial hintereinander und längsaxial versetzt zueinander in gestaffelter Weise in den Aufnahmemulden der Staffeltrommel 22 angeordnet.The cut tobacco rods of twice the length 111, 112, 113 are then transferred to the receiving troughs of a subsequent staggered drum 22 of a second conveyor section A2. On the staggered drum 22, the cut tobacco rods 111, 112, 113 are arranged in a staggered manner transversely axially one behind the other and offset longitudinally to one another in a staggered manner in the receiving troughs of the staggered drum 22.

Danach werden die gestaffelten Tabakstöcke 111, 112, 113 in gestaffelter Weise an die Aufnahmemulden einer Fördertrommel 24 übergeben, so dass die auf der Fördertrommel 24 weitergeförderten gestaffelten Tabakstöcke 111, 112, 113 anschließend an die Aufnahmemulden einer Schiebetrommel 26 übergeben werden, auf der die Tabakstöcke 111, 112, 113 in einer Reihe queraxial hintereinander in Förderrichtung der Tabakstöcke 111, 112, 113 angeordnet werden.The staggered tobacco rods 111, 112, 113 are then transferred in a staggered manner to the receiving troughs of a conveyor drum 24, so that the staggered tobacco rods 111, 112, 113 conveyed further on the conveyor drum 24 are then transferred to the receiving troughs of a sliding drum 26, on which the tobacco rods 111, 112, 113 are arranged in a row transversely one behind the other in the conveying direction of the tobacco rods 111, 112, 113.

Anschließend werden die gebildeten Rauchartikelgruppen 140 von einer nachfolgenden Fördertrommel 36 zu einer (hier nicht dargestellten) Belageinrichtung gefördert, so dass die gebildeten Rauchartikelgruppen 140 von einem Umhüllungsstreifen umhüllt werden. Anschließend kann in einem weiteren (hier nicht dargestellten) Verfahrensschritt vorgesehen sein, dass die gebildeten umhüllten Rauchartikelgruppen 140 mittig geschnitten werden, wodurch stabförmige Rauchprodukte entstehen, die in entsprechenden Vorrichtungen von Rauchern konsumiert werden können.The filter tipping machine F also has a feed device Z for feeding rod-shaped article segments 120 or groups of article segments, by means of which rod-shaped article segments, for example consisting of several different multi-segment filters, are conveyed to the assembly drum 34, so that the article rod segments or rod-shaped article segments 120 between the longitudinally axially spaced pairs of tobacco rod pieces 111.A, 111.B and 112.A, 112.B and 113.A, 113.B for the formation of smoking article groups 140 (cf. 2 ) are inserted in each case. The smoking article groups 140 that are formed are then conveyed by a downstream conveyor drum 36 to a covering device (not shown here), so that the smoking article groups 140 that are formed are wrapped in a wrapping strip. Subsequently, in a further method step (not shown here), provision can be made for the formed, wrapped smoking article groups 140 to be cut in the middle, resulting in rod-shaped smoking products which can be consumed by smokers in corresponding devices.

Gemäß der Erfindung weisen die Übernahmetrommel 12 und die Schneidtrommel 14 im ersten Förderabschnitt A1 einen größeren Teilungsabstand zwischen den Aufnahmemulden auf als die Staffeltrommel 22, die Fördertrommel 24, die Schiebetrommel 26, die (zweite) Schneidtrommel 28 und die Schiebetrommel 32 im zweiten Förderabschnitt A2. Sowohl die Zusammenstelltrommel 34 als auch weitere in Förderrichtung nachfolgende Fördertrommeln können kleinere queraxiale Teilungsabstände zwischen den Aufnahmemulden aufweisen als die Übernahmetrommel 12 und die Schneidtrommel 14 im ersten Förderabschnitt A1.According to the invention, the take-over drum 12 and the cutting drum 14 have a larger pitch in the first conveying section A1 between the receiving troughs as the relay drum 22, the conveyor drum 24, the shift drum 26, the (second) cutting drum 28 and the shift drum 32 in the second conveyor section A2. Both the collating drum 34 and other conveyor drums that follow in the conveying direction can have smaller transverse axial spacings between the receiving troughs than the transfer drum 12 and the cutting drum 14 in the first conveying section A1.

Somit bilden die Trommeln 12, 14 einen ersten Förderabschnitt A1, wobei die Schneidtrommel 14 als erste Schneidtrommel dem ersten Förderabschnitt A1 zugeordnet wird. Von der ersten Schneidtrommel 14 im ersten Förderabschnitt A1 werden aus den Aufnahmemulden der Schneidtrommel 14 die Tabakstöcke 111, 112, 113 in die Aufnahmemulden der Staffelrommel 22 (vgl. Fig. 2) übergeben, wobei der queraxiale Teilungsabstand der Aufnahmemulden der Schneidtrommel 14 größer ist als der Teilungsabstand der Aufnahmemulden der Staffeltrommel 22 des zweiten Förderabschnitts A2, so dass der queraxiale Abstand zwischen den Tabakstöcken 111, 112, 113 bei der Übergabe von der Schneidtrommel 14 an die Staffeltrommel 22 verkürzt wird.The drums 12, 14 thus form a first conveyor section A1, with the cutting drum 14 being assigned to the first conveyor section A1 as the first cutting drum. From the first cutting drum 14 in the first conveyor section A1, the tobacco rods 111, 112, 113 are transferred from the receiving troughs of the cutting drum 14 into the receiving troughs of the relay drum 22 (cf. 2 ) are transferred, with the transverse axial pitch of the receiving troughs of the cutting drum 14 being greater than the pitch of the receiving troughs of the staggered drum 22 of the second conveyor section A2, so that the transverse axial distance between the tobacco rods 111, 112, 113 when they are transferred from the cutting drum 14 to the staggered drum 22 is shortened.

Nach der Übergabe der geschnittenen Tabakstöcke 111, 112, 113 an die Staffeltrommel 22 des zweiten Förderabschnitts wird bzw. ist der queraxiale Abstand zwischen den Tabakstöcken 111, 112, 113 auf den Fördertrommeln im zweiten Förderabschnitt A2 im Vergleich zu den Fördertrommeln im ersten Förderabschnitt A1 verkürzt, wodurch die Bahngeschwindigkeit der geförderten stabförmigen Produkte insgesamt im zweiten Förderabschnitt verringert wird oder ist.After the cut tobacco rods 111, 112, 113 have been transferred to the staggering drum 22 of the second conveyor section, the transverse axial distance between the tobacco rods 111, 112, 113 on the conveyor drums in the second conveyor section A2 is shortened compared to the conveyor drums in the first conveyor section A1 , whereby the web speed of the conveyed rod-shaped products is or is reduced overall in the second conveying section.

Nach der Übergabe der Tabakstöcke 111, 112, 113 von der Schneidtrommel 14 im ersten Förderabschnitt A1 werden die Tabakstöcke 111, 112, 113 an die Fördertrommeln des zweiten Förderabschnitts A2 übergeben, so dass die stabförmigen Produkte auf den Fördertrommeln des zweiten Förderabschnitts A2 mit einem kürzeren queraxialen Abstand gefördert werden.After the tobacco rods 111, 112, 113 have been transferred from the cutting drum 14 in the first conveyor section A1, the tobacco rods 111, 112, 113 are transferred to the conveyor drums of the second conveyor section A2, so that the rod-shaped products on the conveyor drums of the second conveyor section A2 have a shorter transverse axial distance are promoted.

Im Rahmen der Erfindung ist es ebenfalls gemäß einem hier nicht dargestellten alternativen Ausführungsbeispiel möglich, dass sowohl die oder alle Fördertrommeln im ersten Förderabschnitt A1 als auch die oder alle Fördertrommeln im zweiten Förderabschnitt A2 den gleichen Teilungsabstand zwischen den Aufnahmemulden aufweisen. Der zweite Förderabschnitt A2 beginnt dabei nach der Übergabe der auf der ersten Schneidtrommel geschnittenen stabförmigen Artikel in die Aufnahmemulden auf der der Schneidtrommel nachfolgenden Fördertrommel. Der zweite Förderabschnitt endet, wenn die stabförmigen Artikel von einer Fördertrommel des zweiten Förderabschnitts an eine Fördertrommel mit einem größeren oder kleineren queraxialen Teilungsabstand zwischen den Aufnahmemulden übergeben werden.According to an alternative embodiment not shown here, it is also possible within the scope of the invention for both the or all conveyor drums in the first conveyor section A1 and the or all conveyor drums in the second conveyor section A2 to have the same spacing between the receiving troughs. The second conveyor section A2 begins after the transfer of the rod-shaped articles cut on the first cutting drum into the receiving troughs on the conveyor drum following the cutting drum. The second conveyor section ends when the rod-shaped articles are transferred from a conveyor drum of the second conveyor section to a conveyor drum with a larger or smaller transverse-axial spacing between the receiving troughs.
