Ferner betrifft die Erfindung eine Maschine der Tabak verarbeitenden Industrie, insbesondere Multisegmentfilterherstellungsmaschine oder Filteransetzmaschine, sowie eine Verwendung einer Trommelanordnung.Furthermore, the invention relates to a machine in the tobacco processing industry, in particular a multi-segment filter manufacturing machine or filter attachment machine, as well as a use of a drum arrangement.

In Maschinen der Tabak verarbeitenden Industrie, insbesondere Filteransetzmaschinen oder Maschinen zur Herstellung von alternativen Rauchprodukten, wie z.B. Heat-Not-Burn-Produkten oder E-Zigaretten, werden Fördertrommeln eingesetzt, um Zigaretten, Filterstücke oder deren Komponenten zu transportieren.In machines in the tobacco processing industry, especially filter attachment machines or machines for the production of alternative smoking products, such as heat-not-burn products or e-cigarettes, conveyor drums are used to transport cigarettes, filter pieces or their components.

Das Fördern der vorgenannten stabförmigen Gegenstände während der Herstellung von Zigaretten, Filtern sowie Filterzigaretten oder sogenannten Heat-Not-Burn-Produkten oder E-Zigaretten wird bei modernen Produktionsmaschinen der Tabak verarbeitenden Industrie im Allgemeinen mittels Fördertrommeln durchgeführt, deren Mantelfläche bzw. deren Trommelkörper zum queraxialen Fördern von stabförmigen Gegenständen (Zigaretten, Filterstäben oder Filterstopfen, Filterzigaretten) mit Nuten oder Aufnahmemulden zum Aufnehmen der stabförmigen Gegenstände versehen ist. Die Aufnahmemulden weisen hierbei einen Muldengrund auf.The conveying of the aforementioned rod-shaped objects during the manufacture of cigarettes, filters and filter cigarettes or so-called heat-not-burn products or e-cigarettes is generally carried out in modern production machines in the tobacco processing industry by means of conveyor drums, the outer surface or drum body of which is provided with grooves or receiving troughs for receiving the rod-shaped objects for the transverse-axial conveying of rod-shaped objects (cigarettes, filter rods or filter plugs, filter cigarettes). The receiving troughs have a trough base.

Während der Förderung sind diese stabförmigen Artikel der Tabak verarbeitenden Industrie in Aufnahmemulden im Allgemeinen in Reihen queraxial hintereinander angeordnet.During conveying, these rod-shaped articles of the tobacco processing industry are generally arranged in rows transversely axially one behind the other in receiving troughs.

Darüber hinaus sind als Fördertrommeln auch Schiebetrommeln z.B. in Filterzuführeinrichtungen an Filteransetzmaschinen bekannt, auf denen Filterstopfen als stabförmige Artikel längsaxial verschoben werden. Hierbei werden an einer mehrere Transporttrommeln aufweisenden Filterzuführeinrichtung mehrfachlange Filterstäbe aus einem Filterstabmagazin entnommen und in doppeltlange Filterstopfen auf einer Schneidtrommel geschnitten. Nach dem Schneiden werden die Filterstopfen auf einer Staffeltrommel gestaffelt, d.h. jeder geschnittene Filterstopfen wird separat in einer Mulde der Staffeltrommel versetzt zum nächsten Filterstopfen angeordnet. Im Anschluss daran werden die gestaffelten Filterstopfen in einem Verfahrensschritt auf einer Schiebetrommel in den Aufnahmemulden längsaxial verschoben, so dass die Filterstopfen danach in einer Reihe in queraxialer Richtung hintereinander ausgerichtet werden bzw. sind, wodurch die in der Reihe hintereinander angeordneten und ausgerichteten Filterstopfen von der Schiebetrommel an eine nachfolgende Fördertrommel übergeben werden.In addition, sliding drums are also known as conveyor drums, e.g. in filter feed devices on filter attachment machines, on which Filter plugs are moved longitudinally axially as rod-shaped articles. In this case, multiple-length filter rods are taken from a filter rod magazine on a filter feed device having several transport drums and cut into double-length filter plugs on a cutting drum. After cutting, the filter plugs are staggered on a staggering drum, i.e. each cut filter plug is arranged separately in a trough of the staggering drum, offset from the next filter plug. The staggered filter plugs are then moved longitudinally axially in a process step on a sliding drum in the receiving troughs, so that the filter plugs are then aligned one behind the other in a row in the transverse axial direction, whereby the filter plugs arranged and aligned one behind the other in the row are transferred from the sliding drum to a subsequent conveyor drum.

Diese Trommeln werden üblicherweise im Zuge der Konfektionierung von Filterstäben und von Filterzigaretten eingesetzt, wobei Filterstabkomponenten mehrfacher Gebrauchslänge in einem so genannten Querverfahren, d.h. quer zu ihren Längsachsen, durch einmalige oder mehrmalige Unterteilung, Staffelung und Hintereinanderreihung für ihre nachfolgende Verbindung mit weiteren Filterkomponenten oder Rauchartikelkomponenten vorbereitet werden.These drums are usually used in the assembly of filter rods and filter cigarettes, whereby filter rod components of multiple usage lengths are prepared in a so-called transverse process, i.e. transverse to their longitudinal axes, by one or more subdivisions, staggering and arranging them one after the other for their subsequent connection with other filter components or smoking article components.

particular in length, which is further developed in that a further conveyor drum is provided upstream or downstream of the first conveyor drum with respect to the conveying direction of the rod-shaped articles, wherein the further conveyor drum has a drum body rotatable about a rotation axis with receiving troughs for the rod-shaped articles arranged one behind the other in the circumferential direction, wherein a first swash plate and a second swash plate are provided on the two sides of the drum body of the further conveyor drum, each for longitudinally axially displacing the rod-shaped articles in the receiving troughs, wherein the first swash plate of the further conveyor drum is set up to displace rod-shaped articles of the first type in the respective receiving troughs,

Die Erfindung beruht auf dem Gedanken, dass unter Verwendung von zwei beidseitigen Taumelscheiben an einem Trommelkörper der Fördertrommel die in den Aufnahmemulden alternierend angeordneten stabförmigen Artikel der ersten Art und der Artikel der zweiten Art in entgegengesetzte Richtungen längsaxial in den Aufnahmemulden verschoben werden. Hierzu sind für die Bewegung der an beiden Seiten des Trommelkörpers angeordneten Taumelscheiben der ersten Fördertrommel entsprechende jeweilige Bewegungskulissen für die Taumelscheiben vorgesehen. Beispielsweise sind hierbei für die erste Taumelscheibe und die zweite Taumelscheibe jeweils eine Kulissenführung oder dergleichen vorgesehen, um unterschiedliche längsaxiale Verschiebebewegungen der stabförmigen Artikel entsprechend auszuführen bzw. zu bewirken.The invention is based on the idea that, using two swash plates on both sides of a drum body of the conveyor drum, the rod-shaped articles of the first type and the article of the second type arranged alternately in the receiving troughs are displaced in opposite directions longitudinally axially in the receiving troughs. For this purpose, corresponding respective movement guides for the swash plates are provided for the movement of the swash plates of the first conveyor drum arranged on both sides of the drum body. For example, a guide guide or the like is provided for the first swash plate and the second swash plate in order to carry out or bring about different longitudinal axial displacement movements of the rod-shaped articles accordingly.

Mittels der Trommelanordnung bzw. der Fördertrommel werden vorzugsweise in den Aufnahmemulden hintereinander alternierend angeordnete stabförmige Artikel einer ersten Art und einer zweiten Art queraxial gefördert, wobei insbesondere die stabförmigen Artikel der ersten Art sich in der Länge von den stabförmigen Artikeln der zweiten Art unterscheiden. Sowohl für die stabförmigen Artikel der ersten Art als auch für die stabförmigen Artikel der zweiten Art werden die unterschiedlich langen stabförmigen Artikel beispielsweise vor einem Schneidvorgang gegen einen festen Anschlag jeweils, z.B. mittig, ausgerichtet. Hierzu ist jeweils der Anschlagspunkt für die stabförmigen Artikel der ersten Art und auch der Anschlagspunkt für die Artikel der zweiten Art auf der Fördertrommel fest definiert.By means of the drum arrangement or the conveyor drum, rod-shaped articles of a first type and a second type, preferably arranged alternately one behind the other in the receiving troughs, are conveyed transversely axially, with the rod-shaped articles of the first type in particular differing in length from the rod-shaped articles of the second type. For both the rod-shaped articles of the first type and the rod-shaped articles of the second type, the rod-shaped articles of different lengths are each aligned against a fixed stop, e.g. in the middle, before a cutting process. For this purpose, the stop point for the rod-shaped articles of the first type and also the stop point for the articles of the second type are firmly defined on the conveyor drum.

Im Rahmen der Erfindung ist vorzugsweise weiterhin vorgesehen, dass die Kulissenführung für die erste Taumelscheibe für die stabförmigen Artikel der ersten Art und/oder die Kulissenführung für die zweite Taumelscheibe für die stabförmigen Artikel der zweiten Art einstellbar sind, wodurch die Hublänge für die Verschiebebewegung mittels der Taumelscheiben der stabförmigen Artikel der ersten Art und für die stabförmigen Artikel der zweiten Art in den jeweiligen Aufnahmemulden der Fördertrommel, insbesondere unabhängig voneinander, variierbar sind.Within the scope of the invention, it is preferably further provided that the link guide for the first wobble plate for the rod-shaped articles of the first type and/or the link guide for the second wobble plate for the rod-shaped articles of the second type are adjustable, whereby the stroke length for the displacement movement by means of the wobble plates of the rod-shaped Articles of the first type and for the rod-shaped articles of the second type in the respective receiving troughs of the conveyor drum can be varied, in particular independently of one another.

Ferner zeichnet sich eine Weiterbildung der Trommelanordnung dadurch aus, dass an der ersten Taumelscheibe an der den Aufnahmemulden der Fördertrommel zugewandten Seite in Umfangsrichtung der Fördertrommel Stiftkörper vorgesehen sind, wobei die Stiftkörper sich parallel zur Rotationsachse der Fördertrommel erstrecken. In einer Ausgestaltung ist hierbei die erste Trommelscheibe mit den Stiftkörpern für die längsaxiale Bewegung der stabförmigen Artikel der ersten Art, die in der Länge kürzer als die stabförmigen Artikel der zweiten Art sind, in den entsprechenden Aufnahmemulden vorgesehen. Mittels den an den Kopfenden der stabförmigen Artikel der ersten Art ansetzenden Enden der Stiftkörper werden bei einer Hubbewegung der ersten Taumelscheibe während der Rotation der Fördertrommel die stabförmigen Artikel der ersten Art durch die Bewegung der Stiftkörper der ersten Taumelscheibe in längsaxialer Richtung verschoben.Furthermore, a further development of the drum arrangement is characterized in that pin bodies are provided on the first swash plate on the side facing the receiving troughs of the conveyor drum in the circumferential direction of the conveyor drum, wherein the pin bodies extend parallel to the axis of rotation of the conveyor drum. In one embodiment, the first drum plate with the pin bodies is provided for the longitudinal axial movement of the rod-shaped articles of the first type, which are shorter in length than the rod-shaped articles of the second type, in the corresponding receiving troughs. By means of the ends of the pin bodies attached to the head ends of the rod-shaped articles of the first type, the rod-shaped articles of the first type are displaced in the longitudinal axial direction by the movement of the pin bodies of the first swash plate during a lifting movement of the first swash plate during rotation of the conveyor drum.

Ferner zeichnet sich eine Ausgestaltung der Trommelanordnung dadurch aus, dass die zweite Taumelscheibe an der den Aufnahmemulden der Fördertrommel zugewandten Seite flach ausgebildet ist. Hierbei ist die zweite Taumelscheibe der ersten Fördertrommel für die längsaxiale Verschiebebewegung der stabförmigen Artikel der zweiten Art vorgesehen. Ferner ist es im Rahmen der Erfindung in einer Ausgestaltung möglich, dass die zweite Taumelscheibe Stiftkörper für die längsaxiale Bewegung der stabförmigen Artikel der zweiten Art aufweist. Hierbei sind die Stiftkörper an der den Aufnahmemulden der Fördertrommel zugewandten Seite in Umfangsrichtung der Trommel vorgesehen. Die Stiftkörper erstrecken sich hierbei im Wesentlichen parallel zur Rotationsachse der Fördertrommel.Furthermore, one embodiment of the drum arrangement is characterized in that the second swash plate is flat on the side facing the receiving troughs of the conveyor drum. The second swash plate of the first conveyor drum is provided for the longitudinal axial displacement movement of the rod-shaped articles of the second type. Furthermore, within the scope of the invention, it is possible in one embodiment for the second swash plate to have pin bodies for the longitudinal axial movement of the rod-shaped articles of the second type. The pin bodies are provided on the side facing the receiving troughs of the conveyor drum in the circumferential direction of the drum. The pin bodies extend essentially parallel to the axis of rotation of the conveyor drum.

Im Rahmen der Erfindung ist es möglich, dass die seitlich an den Taumelscheiben angeordneten Stiftkörper einstückig mit den jeweiligen Taumelringen der Taumelscheiben ausgebildet sind, so dass der jeweilige Taumelring und die daran angeordneten Stiftkörper aus einem Bauteil gebildet bzw. gedreht sind. D.h. dass aus einem Bauteil für eine Taumelscheibe ein Taumelring und die daran angeordneten Stiftköper eine einteilige Taumelscheibe gebildet wird. In einer alternativen Ausgestaltung ist es im Rahmen der Erfindung möglich, dass einzelne Stiftkörper an den jeweiligen Taumelring mittels entsprechender Befestigungsmittel, z.B. Schrauben oder dergleichen, seitlich angeordnet werden bzw. sind.Within the scope of the invention, it is possible that the swash plates on the sides arranged pin bodies are formed in one piece with the respective wobble rings of the wobble plates, so that the respective wobble ring and the pin bodies arranged thereon are formed or turned from one component. This means that a wobble ring is formed from a component for a wobble plate and the pin bodies arranged thereon form a one-piece wobble plate. In an alternative embodiment, it is possible within the scope of the invention that individual pin bodies are arranged laterally on the respective wobble ring by means of appropriate fastening means, e.g. screws or the like.

Ferner ist bei einer Ausgestaltung der Fördertrommel vorgesehen, dass die Fördertrommel zur queraxialen Förderung von mehr als zwei Arten von stabförmigen Artikeln unterschiedlicher Länge eingerichtet oder ausgebildet ist. Hierbei ist es beispielsweise denkbar, dass die Stiftkörper der Taumelscheiben unterschiedliche Längen aufweisen, um die verschieden langen stabförmigen Artikel mittels der Taumelscheiben entsprechend längsaxial zu verschieben bzw. in den Aufnahmemulden auszurichten.Furthermore, in one embodiment of the conveyor drum, it is provided that the conveyor drum is set up or designed for the transverse axial conveyance of more than two types of rod-shaped articles of different lengths. In this case, it is conceivable, for example, that the pin bodies of the wobble plates have different lengths in order to displace the rod-shaped articles of different lengths longitudinally axially by means of the wobble plates or to align them in the receiving troughs.

Darüber hinaus zeichnet sich eine Weiterbildung der Trommelanordnung dadurch aus, dass der Trommelkörper Aufnahmemulden für die stabförmigen Artikel der ersten Art und Aufnahmemulden für die stabförmigen Artikel der zweiten Art aufweist, wobei die Aufnahmemulden für die stabförmigen Artikel der ersten Art und die Aufnahmemulden für die stabförmigen Artikel der zweiten Art sich in der Länge unterscheiden. Hierbei erstreckt sich die Länge der Aufnahmemulden parallel zur Rotationsachse der Fördertrommel.Furthermore, a further development of the drum arrangement is characterized in that the drum body has receiving troughs for the rod-shaped articles of the first type and receiving troughs for the rod-shaped articles of the second type, wherein the receiving troughs for the rod-shaped articles of the first type and the receiving troughs for the rod-shaped articles of the second type differ in length. The length of the receiving troughs extends parallel to the axis of rotation of the conveyor drum.

Vorzugsweise ist dabei gemäß einem weiteren Aspekt bei der Trommelanordnung vorgesehen, dass die Aufnahmemulden für die stabförmigen Artikel der ersten Art und die Aufnahmemulden für die stabförmigen Artikel der zweiten Art in Umfangsrichtung der Fördertrommel alternierend hintereinander angeordnet sind.Preferably, according to a further aspect, the drum arrangement is provided such that the receiving troughs for the rod-shaped articles of the first type and the receiving troughs for the rod-shaped articles of the second type are arranged alternately one behind the other in the circumferential direction of the conveyor drum.

Darüber hinaus ist in einer Ausführungsform der Trommelanordnung vorteilhafterweise vorgesehen, dass der Trommelkörper der ersten Fördertrommel seitlich angrenzend an die Aufnahmemulden für die stabförmigen Artikel der ersten Art an einer Seite oder an beiden Seiten der Aufnahmemulden eine Vertiefung zur Aufnahme eines Stiftkörpers, insbesondere eines Stiftkörpers der ersten Taumelscheibe der ersten Fördertrommel, aufweist. Durch die Vertiefungen des Trommelkörpers an den Aufnahmemulden für die stabförmigen Artikel der ersten Art wird ermöglicht, dass beispielsweise Stiftkörper einer Taumelscheibe zum längsaxialen Verschieben der stabförmigen Artikel in den Aufnahmemulden eingebracht werden. Im Rahmen der Erfindung ist es ebenfalls denkbar, dass der Trommelkörper derart ausgebildet ist, dass seitlich angrenzend an die Aufnahmemulden für die stabförmigen Artikel der zweiten Art an einer oder an beiden Seiten der Aufnahmemulden jeweils eine Vertiefung zur Aufnahme eines Stiftkörpers vorgesehen ist. Hierbei werden beispielsweise in die Vertiefungen, die an die Aufnahmemulden für die stabförmigen Artikel der zweiten Art angrenzen, Stiftkörper der zweiten Trommelscheibe zum längsaxialen Verschieben der stabförmigen Artikel in den Aufnahmemulden eingebracht.Furthermore, in one embodiment of the drum arrangement, it is advantageously provided that the drum body of the first conveyor drum has a recess for receiving a pin body, in particular a pin body of the first swash plate of the first conveyor drum, laterally adjacent to the receiving troughs for the rod-shaped articles of the first type on one side or on both sides of the receiving troughs. The recesses of the drum body on the receiving troughs for the rod-shaped articles of the first type make it possible, for example, for pin bodies of a swash plate to be introduced into the receiving troughs for the longitudinal axial displacement of the rod-shaped articles. Within the scope of the invention, it is also conceivable that the drum body is designed in such a way that a recess for receiving a pin body is provided laterally adjacent to the receiving troughs for the rod-shaped articles of the second type on one or on both sides of the receiving troughs. In this case, for example, pin bodies of the second drum disc are introduced into the recesses that border the receiving troughs for the rod-shaped articles of the second type for the longitudinal axial displacement of the rod-shaped articles in the receiving troughs.

Durch die längsaxiale Verschiebebewegung der stabförmigen Artikel der ersten Art und die Verschiebebewegung der stabförmigen Artikel der zweiten Art auf der Fördertrommel werden die stabförmigen Artikel beispielsweise in Bezug auf eine Schneidvorrichtung auf der Fördertrommel ausgerichtet. Durch die Anordnung einer Schneidvorrichtung an der Fördertrommel ist die Fördertrommel als Schneidtrommel ausgebildet.Through the longitudinal axial displacement movement of the rod-shaped articles of the first type and the displacement movement of the rod-shaped articles of the second type on the conveyor drum, the rod-shaped articles are aligned, for example, in relation to a cutting device on the conveyor drum. By arranging a cutting device on the conveyor drum, the conveyor drum is designed as a cutting drum.

Ferner zeichnet sich eine Ausgestaltung der Trommelanordnung dadurch aus, dass an der ersten Fördertrommel eine Schneidvorrichtung, insbesondere Schneidmesser, angeordnet ist.Furthermore, an embodiment of the drum arrangement is characterized in that a cutting device, in particular a cutting knife, is arranged on the first conveyor drum.
