  • This is a continuous processing process in which the processing steps are carried out on a quasi-endless tobacco rod.
  • Common is the use of single or multiple strand machines, such as double-strand machines.
  • the processed cut tobacco is first introduced as a tobacco mat in the strand formation zone of the cigarette rod machine, in Form of a shower of isolated tobacco fibers passed in a strand guide channel, the tobacco channel, and accumulated there.

  • the diameter of the tobacco rod results in each case from the dimensions of the tobacco channel, in particular from the width of the tobacco channel defined by the spacing of the tobacco channel wall elements.

  • the respectively to be set distance of the tobacco channel wall elements to each other corresponds to the diameter of the different cigarette types and is in the range of a few millimeters, from about 5 mm to about 9 mm. Therefore, the differences in the different mounting positions, each corresponding to different types of cigarette, only a maximum of a few millimeters. This requires a high accuracy of fit in the connection of tobacco channel wall elements and channel base element.

Description

Die Erfindung betrifft ein Tabakkanalwandelement zumindest mit einer Kanalinnenwandung, einer Kanalaußenwandung und einer zur Befestigung an einem Kanalbasiselement vorgesehenen Basisseitenfläche, wobei das Tabakkanalwandelement an der Basisseitenfläche ein Verbindungsmittel aufweist, das zur passgenauen Befestigung an dem Kanalbasiselement in einer festgelegten Einbaulage ausgebildet ist und zumindest zwei voneinander in einem bestimmten Abstand beabstandete äußere Verbindungselemente umfasst. Ferner betrifft die Erfindung ein Tabakkanalsystem umfassend ein erstes Tabakkanalwandelement, ein zweites Tabakkanalwandelement und ein Kanalbasiselement mit einer Kanalinnenwandung sowie eine Tabakkanalanordnung mit einem ersten Tabakkanalsystem und einem zweiten Tabakkanalsystem.The invention relates to a tobacco channel wall element at least with a channel inner wall, a channel outer wall and provided for attachment to a channel base element base side surface, wherein the tobacco channel wall element on the base side surface has a connecting means which is formed for accurately fitting to the channel base element in a fixed installation position and at least two from each other in comprises a certain distance spaced outer connecting elements. Furthermore, the invention relates to a tobacco channel system comprising a first tobacco channel wall element, a second tobacco channel wall element and a channel base element with a channel inner wall and a tobacco channel arrangement with a first tobacco channel system and a second tobacco channel system.

Ein Tabakkanalwandelement ist z.B. aus der Druckschrift EP-A-1389430 bekannt.A tobacco channel wall element is for example from the document EP-A-1389430 known.

Bei der Herstellung von Tabakprodukten wie Zigaretten, insbesondere filterlosen Zigaretten und Filterzigaretten, wird der Tabak in der Strangbildungszone einer Zigarettenstrangmaschine zunächst in die Form eines fortlaufenden Tabakstrangs gebracht, in der Strangeinheit mit einem Hüllmaterialstreifen umgeben und der so entstehende Zigarettenstrang schließlich in Tabakstäbe einzelner oder mehrfacher Gebrauchslänge unterteilt. Hierbei handelt es sich um einen kontinuierlichen Verarbeitungsprozess, bei dem die Verarbeitungsschritte an einem quasi-endlosen Tabakstrang ausgerührt werden. Üblich ist hierbei der Einsatz von Einzel- oder Mehrfachstrangmaschinen, etwa Doppelstrangmaschinen.In the production of tobacco products such as cigarettes, in particular filterless cigarettes and filter cigarettes, the tobacco is first placed in the strand formation zone of a cigarette rod machine in the form of a continuous tobacco strand, surrounded in the Strangeinheit with a wrapping material strip and the resulting cigarette rod finally in tobacco rods of single or multiple use length divided. This is a continuous processing process in which the processing steps are carried out on a quasi-endless tobacco rod. Common here is the use of single or multiple strand machines, such as double-strand machines.

Um derartige Tabakstränge zu erzeugen, wird zuerst der aufbereitete Schnitt-Tabak als Tabakvlies in die Strangbildungszone der Zigarettenstrangmaschine eingebracht, in Form eines Schauers aus vereinzelten Tabakfasern in einen Strangführungskanal weitergeleitet, dem Tabakkanal, und dort angesammelt. Der Tabakstrang, der sich hierbei bildet, wird dann kontinuierlich über ein Förderungselement mit hoher Fördergeschwindigkeit aus der Strangbildungszone abgeleitet.To produce such tobacco strands, the processed cut tobacco is first introduced as a tobacco mat in the strand formation zone of the cigarette rod machine, in Form of a shower of isolated tobacco fibers passed in a strand guide channel, the tobacco channel, and accumulated there. The tobacco rod that forms in this case is then continuously discharged from the strand formation zone via a high-speed conveying element.

Ein Tabakkanal wird von einem Tabakkanalsystem gebildet, das als Kanalgrundkörper oder -konsole ein horizontales Kanalbasiselement und als Kanalwände zwei im Wesentlichen vertikale Tabakkanalwandelemente aufweist. Die Innenflächen dieser Elemente konstituieren als Kanalinnenwandung den Kanal. Üblicherweise wird eine Anordnung eingesetzt, bei der vereinzelter Tabak dem Tabakkanal von unten zugeleitet und in diesem Tabakkanal an einem Strangförderband als Förderungselement hängend aus der Strangbildungszone herausgeführt wird. Der Tabak wird also von unten nach oben in den Tabakkanal eingebracht, so dass der Tabakkanal an seiner Unterseite offen ist. Das horizontale Kanalbasiselement ist daher als Decke des Tabakkanals ausgebildet, also als dessen obere Begrenzung. Das Strangförderband ist in dieser Anordnung dicht unterhalb des Kanalbasiselements angeordnet und befindet sich daher im oberen Bereich des Tabakkanals.A tobacco channel is formed by a tobacco channel system which has a horizontal channel base element as channel main body or console and two substantially vertical tobacco channel wall elements as channel walls. The inner surfaces of these elements constitute the channel as channel inner wall. Usually, an arrangement is used in which isolated tobacco is fed to the tobacco channel from below and led out in this tobacco channel on a strand conveyor belt as a conveyor element hanging from the strand formation zone. The tobacco is thus introduced from bottom to top in the tobacco channel, so that the tobacco channel is open at its bottom. The horizontal channel base element is therefore formed as a ceiling of the tobacco channel, so as its upper limit. The strand conveyor belt is arranged in this arrangement, just below the channel base member and is therefore located in the upper region of the tobacco channel.

Der Durchmesser des Tabakstrangs ergibt sich jeweils aus den Abmessungen des Tabakkanals, insbesondere aus der durch den Abstand der Tabakkanalwandelemente festgelegten Breite des Tabakkanals. Da der Durchmesser des Tabakstrangs den Durchmesser der Zigarette als Endprodukt festlegt, werden die Abmessungen des Tabakkanals stets so gewählt, dass sie mit dem jeweils erwünschten Durchmesser des Endprodukts korrespondieren.The diameter of the tobacco rod results in each case from the dimensions of the tobacco channel, in particular from the width of the tobacco channel defined by the spacing of the tobacco channel wall elements. Since the diameter of the tobacco rod sets the diameter of the cigarette as the final product, the dimensions of the tobacco channel are always chosen so that they correspond to the respective desired diameter of the final product.

Im Rahmen einer optimalen Ausnutzung der Produktionskapazität von Maschinen zur Zigarettenherstellung ist es erforderlich, auf einer einzigen Maschine verschiedene Zigarettentypen herstellen zu können. Dafür ist es wichtig, dass eine jeweils erforderliche Umrüstung der Maschine von dem einen Zigarettentypen auf den anderen Zigarettentypen möglichst schnell ausgeführt werden kann. Da sich die unterschiedlichen Zigarettentypen auch hinsichtlich ihres Durchmessers unterscheiden können, beinhaltet eine derartige Umrüstung häufig auch die Anpassung der Breite des Tabakkanals. Hierzu werden die Tabakkanalwandelemente von dem horizontalen Kanalbasiselement gelöst werden, entsprechend der erwünschten Breite des Tabakkanals angepasst und in der neuen Einbaulage wieder an dem Kanalbasiselement befestigt.In order to make optimum use of the production capacity of cigarette making machines, it is necessary to be able to produce different cigarette types on a single machine. For this it is important that a required conversion of the machine from one type of cigarette to the other types of cigarette can be performed as quickly as possible. Since the different types of cigarette can also differ in terms of their diameter, such a conversion often also includes the adaptation of the width of the tobacco channel. For this purpose, the tobacco channel wall elements of the horizontal Channel base element to be solved, adapted according to the desired width of the tobacco channel and fixed in the new mounting position again to the channel base member.

Der jeweils einzustellende Abstand der Tabakkanalwandelemente zueinander entspricht dem Durchmesser der unterschiedlichen Zigarettentypen und liegt im Bereich einiger Millimeter, von etwa 5 mm bis etwa 9 mm. Daher betragen auch die Unterschiede in den unterschiedlichen Einbaulagen, die jeweils verschiedenen Zigarettentypen entsprechen, nur maximal wenige Millimeter. Dies erfordert eine hohe Passgenauigkeit bei der Verbindung von Tabakkanalwandelementen und Kanalbasiselement. Bei der Wahl der Verbindungsmittel ist man daher auf spezielle Verbindungsarten mit hoher Passgenauigkeit festgelegt, so dass beispielsweise herkömmliche Schraubverbindungen nicht zum Einsatz gelangen können, da die Gewinde der Einzelkomponenten ein Spiel von jeweils 0,5 mm aufweisen.The respectively to be set distance of the tobacco channel wall elements to each other corresponds to the diameter of the different cigarette types and is in the range of a few millimeters, from about 5 mm to about 9 mm. Therefore, the differences in the different mounting positions, each corresponding to different types of cigarette, only a maximum of a few millimeters. This requires a high accuracy of fit in the connection of tobacco channel wall elements and channel base element. In the choice of connecting means is therefore set to special types of connections with high accuracy of fit, so that, for example, conventional screw can not be used, since the threads of the individual components have a play of 0.5 mm.

Aufgrund dieser hohen Anforderungen an die Verbindungsmittel werden üblicherweise Tabakkanalwandelemente und Kanalbasiselemente verwendet, die jeweils nur für eine einzige Einbaulage geeignet sind, so dass eine Anpassung des Tabakkanalsystems an unterschiedliche Kanalbreiten regelmäßig mit einem Austausch der Tabakkanalwandelemente und des dazugehörigen Kanalbasiselements verbunden ist. Soll daher eine einzelne Zigarettenstrangmaschine für verschiedene Zigarettentypen ausgelegt sein, so muss für jede erwünschte Kanalbreite jeweils ein spezifisch auf diese Breite angepasster Satz Tabakkanalwandelemente mit jeweils einem entsprechenden Kanalbasiselement vorhanden sein. Bei Mehrstrangmaschinen können die zwei Kanalwände zwischen zwei parallelen benachbarten Kanälen jedoch auch als ein einziges Tabakkanaldoppelwandelement zusammengefasst sein, so dass in diesem Fall für die Anpassung beider Tabakkanäle jeweils nur vier Elemente anstelle von fünf oder sogar sechs Elementen zu wechseln sind.Due to these high demands on the connecting means tobacco channel wall elements and channel base elements are usually used, which are only suitable for a single installation position, so that an adjustment of the tobacco channel system to different channel widths is regularly connected to an exchange of the tobacco channel wall elements and the associated channel base element. If, therefore, a single cigarette rod machine is to be designed for different cigarette types, then for each desired channel width, a set of tobacco channel wall elements, each adapted specifically to this width, must be present, each with a corresponding channel base element. In multi-strand machines, however, the two channel walls between two parallel adjacent channels may also be combined as a single tobacco channel double wall element, so that in this case only four elements instead of five or even six elements have to be changed for the adaptation of both tobacco channels.

Infolge des hohen Tabakdurchsatzes in Anlagen zur Zigarettenfertigung sind gerade die Tabakkanalwandelemente besonders hohen mechanische Beanspruchung ausgesetzt und unterliegen daher einem starken Verschleiß. Dies führt dazu, dass nicht bloß mehrere Tabakkanalwandelemente vorrätig sein müssen, nämlich je ein Satz für jeden Zigarettendurchmesser, sondern zusätzlich für jeden Zigarettendurchmesser auch noch mehrere identische Sätze, um bei Verschleiß zügig ausgetauscht werden zu können. Nachteilig an derartigen Tabakkanalsystemen ist demnach das Erfordernis einer aufwändige Lagerhaltung, um eine verzögerungsarme Produktion gewährleisten zu können.As a result of the high tobacco throughput in systems for cigarette production just the tobacco channel wall elements are exposed to particularly high mechanical stress and are therefore subject to heavy wear. This means that not just several tobacco channel wall elements must be in stock, namely one set for each Cigarette diameter, but also for each cigarette diameter even more identical sets to be quickly replaced when worn can. A disadvantage of such tobacco channel systems is therefore the requirement of an expensive storage in order to ensure a low-delay production.

Alternativ zu einem Wechsel des Systems Tabakkanalwandelemente/Kanalbasiselement ist es auch möglich, ein einziges Tabakkanalwandelement zur Realisierung unterschiedlicher Kanalbreiten einzusetzen. Ein derartiges Tabakkanalwandelement für verschiedene Kanalwandabstände erfordert jedoch die Verwendung zusätzlicher Distanzstücke oder Abstandhalter, um das Tabakkanalwandelement relativ zu dem Kanalbasiselement in unterschiedlichen Einbaulagen befestigen zu können. In diesem Fall sind also nicht die Tabakkanalwandelemente, sondern lediglich die Distanzstücke oder Abstandhalter an die jeweilige Kanalbreite angepasst. Auch wenn sich so unterschiedliche Tabakkanalwandelementabstände jeweils mit nur einem Typ Tabakkanalwandelemente erreichen lassen, so hat dies den Nachteil, dass durch die Verwendung von Distanzstücken oder Abstandhaltern die Komplexität der Konstruktion erheblich steigt, wenn auf diese Weise dennoch eine spielarme und feste Verbindung von Tabakkanalwandelementen und Kanalbasiselement sicher gestellt sein soll. Zudem ist ein derartiges Tabakkanalwandsystem gegenüber mechanischen Belastungen deutlich anfälliger. Schließlich ist auch hier jeweils mindestens ein Satz zusätzlicher Elemente vorrätig zu halten, um unterschiedliche Kanalbreiten realisieren zu können, nämlich die entsprechend angepassten Distanzstücke oder Abstandhalter.As an alternative to a change of the system tobacco channel wall elements / channel base element, it is also possible to use a single tobacco channel wall element for the realization of different channel widths. However, such a tobacco channel wall element for different channel wall spacings requires the use of additional spacers or spacers in order to fix the tobacco channel wall element relative to the channel base member in different mounting positions can. In this case, therefore, not the tobacco channel wall elements, but only the spacers or spacers are adapted to the respective channel width. Even if so different tobacco channel wall element distances can be achieved with only one type tobacco channel wall elements, so this has the disadvantage that by the use of spacers or spacers, the complexity of the design increases considerably, if in this way still a low-backlash and firm connection of tobacco channel wall elements and channel base element should be ensured. In addition, such a tobacco channel wall system is much more susceptible to mechanical stress. Finally, at least one set of additional elements is to be kept in stock here in order to be able to realize different channel widths, namely the appropriately adapted spacers or spacers.

Eine Aufgabe der vorliegenden Erfindung ist es daher, ein Tabakkanalwandelement zur Verfügung zu stellen, das diese Nachteile beseitigt, das insbesondere als einfache Konstruktion ausführbar ist und eine belastbare und gleichzeitig passgenaue Befestigung an dem Kanalbasiselement in festgelegten Einbaulagen ermöglicht und dabei wieder verwendet werden kann, ohne dass für jede Einbaulage zusätzliche spezifische Elemente verwendet werden müssen. Eine weitere Aufgabe der Erfindung besteht darin, ein Tabakkanalsystem bereit zu stellen, dass für unterschiedliche Kanalbreiten anpassbar ist, ohne dass zur Anpassung jeweils zusätzliche spezifische Elemente erforderlich sind, sowie eine Tabakkanalanordnung mehrerer derartiger Tabakkanalsysteme.An object of the present invention is therefore to provide a tobacco channel wall element which eliminates these disadvantages, which can be executed in particular as a simple construction and enables a reliable and at the same time accurately fitting attachment to the channel base element in fixed mounting positions and can be reused without that additional specific elements must be used for each installation position. Another object of the invention is to provide a tobacco channel system that is adaptable to different channel widths without additional specific ones for adaptation Elements are required, as well as a tobacco channel arrangement of several such tobacco channel systems.

Diese Aufgabe wird erfindungsgemäß durch ein Tabakkanalwandelement der eingangs genannten Art gelöst, an dessen Basisseitenfläche zusätzlich zu dem bereits genannten ersten Verbindungsmittel, das zur passgenauen Befestigung an dem Kanalbasiselement in einer festgelegten ersten Einbaulage ausgebildet ist und zumindest zwei voneinander in einem bestimmten ersten Abstand beabstandete äußere Verbindungselemente umfasst, weiterhin mindestens ein zweites Verbindungsmittel vorgesehen ist, das zur passgenauen Befestigung an dem Kanalbasiselement in einer von der ersten Einbaulage verschiedenen festgelegten zweiten Einbaulage ausgebildet ist und zumindest zwei voneinander in einem bestimmten zweiten Abstand beabstandete äußere Verbindungselemente umfasst. Auf diese Weise ist es zum einen möglich, ein einziges Tabakkanalwandelement für unterschiedliche Einbaulagen verwenden zu können. Zusätzlich erlaubt die Anordnung der Verbindungsmittel direkt an der Basisseitenfläche insbesondere bei einem Tabakkanalwandelement mit mehreren Verbindungsmitteln eine besonders einfache Konstruktion des Verbindungssystems, da auf zusätzliche Elemente wie etwa Abstandhalter oder dergleichen verzichtet werden kann. Über die beabstandete Anordnung der zumindest zwei Verbindungselemente wird zusätzlich zu der Passgenauigkeit eine ausreichend hohe Belastbarkeit der Verbindung gegenüber seitlich einwirkenden Kräften erzielt. Erst diese drei Faktoren zusammen erfüllen die Voraussetzungen, die in technischer Hinsicht an ein in unterschiedlichen Einbaulagen einsetzbares Tabakkanalwandelement gestellt werden. Es sei darauf hingewiesen, dass erfindungsgemäß ein Verbindungsmittel natürlich auch mehr als zwei Verbindungselemente aufweisen kann; derartige weitere Verbindungselemente sind in diesem Fall als innere Verbindungselemente zwischen den zuvor genannten äußeren Verbindungselementen dieses Verbindungsmittels angeordnet.This object is achieved by a tobacco channel wall element of the type mentioned above, at its base side surface in addition to the already mentioned first connecting means, which is designed for accurately fitting to the channel base element in a fixed first installation position and at least two spaced from each other at a certain first distance outer connecting elements Furthermore, at least one second connecting means is provided, which is designed to fit accurately to the channel base element in a different from the first mounting position fixed second mounting position and at least two spaced from each other at a certain second distance outer connecting elements. In this way, it is firstly possible to use a single tobacco channel wall element for different mounting positions. In addition, the arrangement of the connecting means directly on the base side surface, in particular in a tobacco channel wall element with a plurality of connecting means allows a particularly simple construction of the connection system, as can be dispensed with additional elements such as spacers or the like. By means of the spaced arrangement of the at least two connecting elements, in addition to the accuracy of fit, a sufficiently high load-bearing capacity of the connection with respect to laterally acting forces is achieved. Only these three factors together meet the requirements that are technically set to be used in different mounting positions tobacco channel wall element. It should be noted that, according to the invention, a connecting means can naturally also have more than two connecting elements; Such further connecting elements are arranged in this case as inner connecting elements between the aforementioned outer connecting elements of this connecting means.

Dabei ist es zudem günstig, wenn die Verbindungselemente des ersten Verbindungsmittels und die Verbindungselemente des zweiten Verbindungsmittels für eine formschlüssige Verbindung des Tabakkanalwandelements mit dem Kanalbasiselement an der Basisseitenfläche des Tabakkanalwandelements ausgebildet sind. Bei derartigen formschlüssigen Verbindungen ist es möglich, eine Toleranz einzuhalten, das heißt die Abweichungen der tatsächlichen Abmessungen vom jeweiligen Normmaß, die jeweils sehr gering ist. Dadurch wird also eine besonders passgenaue Verbindung zwischen dem Tabakkanalwandelement und dem Kanalbasiselement ermöglicht. Sind etwa die Verbindungselemente des ersten Verbindungsmittels und die Verbindungselemente des zweiten Verbindungsmittels Zylinderbohrungen, die zur Aufnahme von Zylinderstiften (als Verbindungsmittlungselemente) ausgebildet sind, so wird zudem die Fertigung der Tabakkanalwandelemente dadurch stark vereinfacht, dass die Basisseitenflächen der Tabakkanalwandelemente lediglich mit Verbindungselementen in Form von Präzisionsbohrungen versehen werden müssen. Sind die Verbindungselemente des ersten Verbindungsmittels und die Verbindungselemente des zweiten Verbindungsmittels hingegen Nutelemente zur Aufnahme von Federelementen, so wird hierbei zusätzlich zur hohen Passgenauigkeit der Vorteil geboten, dass auf zusätzliche Hilfselemente wie etwa Verbindungsmittlungselemente verzichtet werden kann, zum Beispiel auf Zylinderstifte.It is also advantageous if the connecting elements of the first connecting means and the connecting elements of the second connecting means for a positive connection of the tobacco channel wall element with the channel base element are formed on the base side surface of the tobacco channel wall element. In such positive connections, it is possible to have a tolerance To comply with, that is, the deviations of the actual dimensions of the respective standard size, which is very low. As a result, a particularly precisely fitting connection between the tobacco channel wall element and the channel base element is thus made possible. For example, if the connecting elements of the first connecting means and the connecting elements of the second connecting means cylinder bores, which are designed to accommodate cylindrical pins (as Verbindungsmittlungselemente), so the production of tobacco channel wall elements is greatly simplified by the fact that the base side surfaces of the tobacco channel wall elements only with fasteners in the form of precision holes must be provided. If the connecting elements of the first connecting means and the connecting elements of the second connecting means, however, groove elements for receiving spring elements, this is in addition to high accuracy of fit the advantage offered that can be dispensed with additional auxiliary elements such as Verbindungsmittlungselemente, for example on cylindrical pins.

Vorteilhaft ist es hierbei, wenn der erste Abstand von dem zweiten Abstand verschieden ist. Durch diese Ausbildung werden Fehler beim Befestigen eines Tabakkanalwandelements an dem Kanalbasiselement vermieden, etwa eine Schrägstellung der Tabakkanalwandelemente, da es aufgrund der verschiedenen Abstände nicht möglich ist, irrtümlich die Verbindungselemente des ersten Verbindungsmittels des Tabakkanalwandelements mit den Verbindungselementen des zweiten Verbindungsmittels dem Kanalbasiselement zu verbinden und umgekehrt. Besonders vorteilhaft ist es dabei, wenn der erste Abstand größer ist als der zweite Abstand und wenn die Verbindungselemente des zweiten Verbindungsmittels hinsichtlich der Längsrichtung des Tabakkanalwandelements zwischen den Verbindungselementen des ersten Verbindungsmittels angeordnet sind. Infolge einer solchen Ausbildung wird vom Bedienungspersonal bereits beim Einbau intuitiv erkannt, welches Verbindungselement für welche der möglichen Einbaulagen ausgebildet ist.It is advantageous here if the first distance is different from the second distance. This design avoids errors in attaching a tobacco channel wall member to the channel base member, such as skewing of the tobacco channel wall members, because it is not possible due to the different distances to erroneously connect the connecting elements of the first connecting means of the tobacco channel wall element with the connecting elements of the second connecting means the channel base member and vice versa , It is particularly advantageous if the first distance is greater than the second distance and if the connecting elements of the second connecting means are arranged with respect to the longitudinal direction of the tobacco channel wall element between the connecting elements of the first connecting means. As a result of such training is already intuitively recognized by the operator during installation, which connecting element is designed for which of the possible mounting positions.

Günstig ist es ferner, wenn zumindest ein Teilabschnitt der Kanalinnenwandung aus Hartmetall ausgebildet ist. Auf diese Weise wird die Abnutzung des Tabakkanalwandelements aufgrund mechanischer Belastung verringert.It is also advantageous if at least a portion of the channel inner wall is formed of hard metal. In this way, the wear of the tobacco channel wall element is reduced due to mechanical stress.

Schließlich ist es vorteilhaft, wenn das erste Verbindungsmittel und das zweite Verbindungsmittel weiterhin zumindest ein Sicherungselement zum Sichern der Verbindung zwischen dem Tabakkanalwandelement und dem Kanalbasiselement umfasst, zum Beispiel in Form von Schraubverbindungen. Hierdurch ist es möglich, die Verbindung zwischen dem Tabakkanalwandelement und dem Kanalbasiselement nicht nur gegen eine seitliche Belastung, sondern zusätzlich auch gegen eine etwaige Zugbelastung zu sichern.Finally, it is advantageous if the first connection means and the second connection means further comprise at least one securing element for securing the connection between the tobacco channel wall element and the channel base element, for example in the form of screw connections. This makes it possible to secure the connection between the tobacco channel wall element and the channel base element not only against a lateral load, but in addition against a possible tensile load.

Ferner wird die Aufgabe durch das Tabakkanalsystem der eingangs beschriebenen Art gelöst, bei dem zumindest eines der beiden Tabakkanalwandelemente ein erfindungsgemäßes Tabakkanalwandelement ist und bei dem das Kanalbasiselement an der Kanalinnenwandung ein erstes Verbindungsmittel aufweist, das zur passgenauen Befestigung mittels des ersten Verbindungsmittels des zumindest einen erfindungsgemäßen Tabakkanalwandelements an diesem Tabakkanalwandelement in der ersten Einbaulage ausgebildet ist, wobei das erste Verbindungsmittel des Kanalbasiselements zu dem ersten Verbindungsmittel dieses Tabakkanalwandelements komplementär eingerichtet ist, und dass das Kanalbasiselement an der Kanalinnenwandung ein zweites Verbindungsmittel aufweist, das zur passgenauen Befestigung mittels des zweiten Verbindungsmittels des zumindest einen erfindungsgemäßen Tabakkanalwandelements an diesem Tabakkanalwandelement in der zweiten Einbaulage ausgebildet ist, wobei das zweite Verbindungsmittel des Kanalbasiselements zu dem zweiten Verbindungsmittel dieses Tabakkanalwandelements komplementär eingerichtet ist. Ein derartiges Tabakkanalsystem bietet den Vorteil, dass mit wenigen Elementen Tabakkanäle unterschiedlicher Breiten gebildet werden können, die gleichzeitig hinsichtlich Belastbarkeit und Passgenauigkeit den besonderen technischen Erfordernissen der Zigarettenfertigung genügen, ohne dass dabei für jede Tabakkanalbreite unterschiedliche Einzelelemente verwendet werden müssen.Furthermore, the object is achieved by the tobacco channel system of the type described above, in which at least one of the two tobacco channel wall elements is a tobacco channel wall element according to the invention and in which the channel base element on the channel inner wall has a first connection means for precisely fitting attachment by means of the first connection means of the at least one tobacco channel wall element according to the invention is formed on this tobacco channel wall element in the first installation position, wherein the first connecting means of the channel base member is complementary to the first connecting means of this tobacco channel wall element, and in that the channel base member on the channel inner wall has a second connection means for the precise attachment by means of the second connecting means of the at least one inventive Tobacco channel wall element is formed on this tobacco channel wall element in the second mounting position, wherein the second connecting means of the K analbasiselements is set up complementary to the second connecting means of this tobacco channel wall element. Such a tobacco channel system offers the advantage that with a few elements tobacco channels of different widths can be formed, which at the same time meet the special technical requirements of cigarette production in terms of resilience and accuracy of fit without having to use different individual elements for each tobacco channel width.

Schließlich stellt die Erfindung eine Tabakkanalanordnung zur Verfügung, bei der das Kanalbasiselement des ersten Tabakkanalsystems ebenfalls als Kanalbasiselement des zweiten Tabakkanalsystems ausgebildet ist, an dem das erste Tabakkanalwandelement des ersten Tabakkanalsystems, das zweite Tabakkanalwandelement des ersten Tabakkanalsystems, das erste Tabakkanalwandelement des zweiten Tabakkanalsystems und das zweite Tabakkanalwandelement des zweiten Tabakkanalsystems jeweils passgenau befestigbar sind. Auf diese Weise wird gerade für Doppelstrangmaschinen eine besonders einfache, Platz sparende und auch hinsichtlich der Anpassung der Kanalbreite flexible Konstruktion paralleler Tabakkanäle erreichbar.Finally, the invention provides a tobacco channel arrangement in which the channel base element of the first tobacco channel system is likewise designed as a channel base element of the second tobacco channel system, on which the first tobacco channel wall element the first tobacco channel system, the second tobacco channel wall element of the first tobacco channel system, the first tobacco channel wall element of the second tobacco channel system and the second tobacco channel wall element of the second tobacco channel system are each accurately fit fastened. In this way, a particularly simple, space-saving and also with regard to the adaptation of the channel width flexible construction parallel tobacco channels can be achieved especially for double-strand machines.

Die Erfindung soll im folgenden unter Bezugnahme auf die beigefügten Zeichnungen eines besonders vorteilhaften Ausführungsbeispiels ohne Beschränkung des diesem Ausführungsbeispiel zugrunde liegenden allgemeinen Erfindungsgedankens näher beschrieben werden, woraus sich auch weitere Vorteile des erfindungsgemäßen Gedankens ergeben. Dabei zeigt

  • Fig. 1 eine perspektivische schematische Darstellung eines Paares erfindungsgemäßer Tabakkanalwandelemente und
  • Fig. 2 eine perspektivische schematische Darstellung eines Kanalbasiselements des Tabakkanalsystems einer Tabakkanalanordnung für eine Doppelstrangmaschine.
The invention will be described in more detail below with reference to the accompanying drawings of a particularly advantageous embodiment without limiting the general inventive concept underlying this embodiment, resulting in further advantages of the inventive concept. It shows
  • Fig. 1 a perspective schematic representation of a pair of inventive tobacco channel wall elements and
  • Fig. 2 a perspective schematic representation of a channel base element of the tobacco channel system of a tobacco channel assembly for a double-strand machine.

In Fig. 1 ist ein Paar der erfinderischen Tabakkanalwandelemente 1, 1' dargestellt, die gemeinsam die seitlichen Wände eines Tabakkanals in der Strangbildungszone einer Zigarettenstrangmaschine bilden. Die in Fig. 1 dargestellte paarweise Anordnung entspricht im Wesentlichen der parallelen Anordnung innerhalb eines Tabakkanalsystems, bei dem zusätzlich noch ein komplementär ausgebildetes Kanalbasiselement enthalten ist. Ein derartiges Kanalbasiselement 2 ist in Fig. 2 dargestellt. Es sei darauf hingewiesen, dass bei den in Fig. 1 gezeigten Tabakkanalwandelementen 1, 1' aus Gründen der Übersichtlichkeit der Abstand der Tabakkanalwandelemente 1, 1' zueinander größer gewählt wurde als dies in einem tatsächlichen Tabakkanalsystem der Fall wäre.In Fig. 1 For example, a pair of the inventive tobacco channel wall elements 1, 1 'are shown which together form the lateral walls of a tobacco channel in the strand formation zone of a cigarette rod making machine. In the Fig. 1 shown paired arrangement substantially corresponds to the parallel arrangement within a tobacco channel system, in which additionally a complementarily formed channel base element is included. Such a channel base element 2 is in Fig. 2 shown. It should be noted that in the in Fig. 1 shown tobacco channel wall elements 1, 1 'for reasons of clarity, the distance of the tobacco channel wall elements 1, 1' each selected larger than would be the case in an actual tobacco channel system.

Die in Fig. 1 wiedergegebenen Tabakkanalwandelemente 1,1' sind als schmale leistenartige Bauteile ausgeführt, deren Abmessungen in Längsrichtung größer sind als die Abmessungen in den Querrichtungen und die zumeist aus Metall gefertigt sind. Wie aus Fig. 1 erkennbar ist, ist die genaue Form der Tabakkanalwandelemente 1, 1' an die jeweilige Ausbildung der Strangbildungszone in der Zigarettenstrangmaschine angepasst; so weisen beide Tabakkanalwandelemente 1, 1' besondere Ausgestaltungen wie etwa Aussparungen auf, um die Tabakkanalwandelemente 1, 1' in die Strangbildungszone einpassen zu können.In the Fig. 1 reproduced tobacco channel wall elements 1,1 'are designed as narrow strip-like components whose dimensions are larger in the longitudinal direction than the dimensions in the transverse directions and which are mostly made of metal. As out Fig. 1 can be seen, the exact shape of the tobacco channel wall elements 1, 1 'adapted to the respective formation of the strand formation zone in the cigarette rod machine; Thus, both tobacco channel wall elements 1, 1 'on special designs such as recesses in order to fit the tobacco channel wall elements 1, 1' in the strand formation zone can.

Jedes Tabakkanalwandelement 1,1' weist an seinen vertikalen Seiten zwei Stirnseitenflächen sowie eine Kanalinnenwandung (an den einander zugekehrten Seiten) und eine Kanalaußenwandung (an den einander abgekehrten Seiten) auf. Außerdem weisen die Tabakkanalwandelemente 1, 1' an ihren horizontalen Seiten je eine untere Seitenfläche sowie eine obere Seitenfläche auf. An der oberen Seitenfläche, der Basisseitenfläche, befinden sich Verbindungsmittel, um die Basisseitenfläche eines Tabakkanalwandelements 1,1' unter Zuhilfenahme von Verbindungsmittlungselementen mit dem Kanalbasiselement 2 formschlüssig zu verbinden.Each tobacco channel wall element 1,1 'has on its vertical sides two end faces and a channel inner wall (on the sides facing each other) and a Kanalaußenwandung (on the opposite sides) on. In addition, the tobacco channel wall elements 1, 1 'each have a lower side surface and an upper side surface on their horizontal sides. On the upper side surface, the base side surface, there are connection means for positively connecting the base side surface of a tobacco channel wall element 1, 1 'to the channel base element 2 with the aid of connection determination elements.

An den einander zugekehrten Kanalinnenwandungen weisen die Tabakkanalwandelemente 1, 1' jeweils Teilabschnitte 16, 16' auf, die aus Hartmetallen großer Härte und von hoher Verschleißfestigkeit bestehen, etwa aus gesinterten Karbidhartmetallen. Bei diesen Teilabschnitten 16, 16' handelt es sich um die Bereiche, die als Prallflächen für von unten in den Tabakkanal eingebrachte Tabakfasern und als Reibeflächen für den aus der Strangbildungszone heraus geförderten Tabakstrang besonders hohen mechanischen Belastungen ausgesetzt sind. Natürlich kann auch die gesamte Kanalinnenwandung aus Hartmetall bestehen.At the mutually facing channel inner walls, the tobacco channel wall elements 1, 1 'in each case sections 16, 16', which consist of hard metals of high hardness and high wear resistance, such as sintered carbide carbides. These subsections 16, 16 'are the areas which are exposed to particularly high mechanical loads as baffles for tobacco fibers introduced from below into the tobacco channel and as friction surfaces for the tobacco strand conveyed out of the strand formation zone. Of course, the entire channel inner wall made of hard metal.

Die Hartmetallelemente der Teilabschnitte 16, 16' sind an den Tabakkanalwandelementen 1,1' mit einem hochfesten Klebstoff verklebt und zusätzlich über Schraubverbindungen gesichert, die mittels Schrauben bewirkt werden, die in Bohrungen an den Kanalaußenwandungen eingeführt sind. Zur Verringerung des Widerstandes der von unten in den Tabakkanal eingetragenen Tabakfasern weisen die Teilabschnitte an ihrer unteren Innenkante jeweils Fasen auf.The hard metal elements of the sections 16, 16 'are glued to the tobacco channel wall elements 1,1' with a high-strength adhesive and additionally secured by screw, which are effected by means of screws which are inserted into bores on the Kanalaußenwandungen. In order to reduce the resistance of tobacco fibers introduced from below into the tobacco channel, the sections have respective chamfers at their lower inner edge.

Die Verbindungsmittel des vorderen Tabakkanalwandelements 1 umfassen das erste Verbindungsmittel mit zwei Zylinderbohrungen 11, 13 als Verbindungselemente sowie das zweite Verbindungsmittel mit zwei Zylinderbohrungen 12, 14 als Verbindungselemente. Die Zylinderbohrungen 11, 12, 13, 14 sind zur Aufnahme von Zylinderstiften ausgebildet und daher Präzisionsbohrungen mit geringer Toleranz, also mit geringer Maß- und Formtoleranz. Zur Verbindung mit dem Kanalbasiselement 2 werden entweder in beide Zylinderbohrungen 11, 13 des ersten Verbindungsmittels oder aber in beide Zylinderbohrungen 12, 14 des zweiten Verbindungsmittels Zylinderstifte (in den Abbildungen nicht dargestellt) als Verbindungsmittlungselemente eingeführt. Es sei darauf hingewiesen, dass auch wenn im Folgenden lediglich das vordere Tabakkanalwandelement 1 explizit beschrieben ist, Entsprechendes jeweils auch für das hintere Tabakkanalwandelement 1' mit dessen ersten und zweiten Verbindungsmitteln gilt, die jeweils die Zylinderbohrungenpaare 11', 13' und 12', 14' umfassen.The connecting means of the front tobacco channel wall element 1 comprise the first connecting means with two cylinder bores 11, 13 as connecting elements and the second connecting means with two cylinder bores 12, 14 as connecting elements. The cylinder bores 11, 12, 13, 14 are designed to receive cylindrical pins and therefore precision holes with low tolerance, ie with low dimensional and shape tolerance. For connection to the channel base member 2, cylindrical pins (not shown in the figures) are introduced as connection detection elements either in both cylinder bores 11, 13 of the first connection means or in both cylinder bores 12, 14 of the second connection means. It should be noted that even if only the front tobacco channel wall element 1 is explicitly described below, the same applies in each case to the rear tobacco channel wall element 1 'with its first and second connecting means, in each case the cylinder bore pairs 11', 13 'and 12', 14 'include.

Die Zylinderstifte sind mit ähnlich geringer Toleranz gefertigt wie die Zylinderbohrungen 11, 12, 13, 14 des Tabakkanalwandelements 1, so dass jeder Zylinderstift nahezu spielfrei von den Zylinderbohrungen 11, 12, 13, 14 aufgenommen wird. Die Länge der Zylinderstifte ist jeweils in etwa doppelt groß ist wie die Tiefe der Zylinderbohrungen 11, 12, 13, 14. Daher ragen die Endabschnitte der in die Zylinderbohrungen 11, 12, 13, 14 eingesetzten Zylinderstifte aus den Zylinderbohrungen 11, 12, 13, 14 heraus. Diese Endabschnitte werden in die in Fig. 2 dargestellten Zylinderbohrungen 21, 22, 23, 24 des Kanalbasiselements 2 eingeführt, die ebenfalls mit geringer Toleranz gefertigt sind, so dass sich die Zylinderstifte dort daher nahezu spielfrei einfügen lassen. Durch Verwendung einer derartigen Zylinderstiftverbindung wird also eine insgesamt nahezu spielfreie und somit passgenaue Verbindung zwischen dem Tabakkanalwandelement 1 und dem Kanalbasiselement 2 geschaffen.The cylinder pins are manufactured with a similarly low tolerance as the cylinder bores 11, 12, 13, 14 of the tobacco channel wall element 1, so that each cylinder pin is received almost free of play by the cylinder bores 11, 12, 13, 14. The length of the cylindrical pins is approximately twice as large as the depth of the cylinder bores 11, 12, 13, 14. Therefore, the end portions of the cylinder pins inserted into the cylinder bores 11, 12, 13, 14 protrude from the cylinder bores 11, 12, 13, 14 out. These end sections are in the in Fig. 2 shown cylinder bores 21, 22, 23, 24 of the channel base member 2 introduced, which are also made with low tolerance, so that there can be inserted the cylinder pins there almost free of play. By using such a dowel pin connection, therefore, an overall connection between the tobacco channel wall element 1 and the channel base element 2 that is virtually free from play and thus fits precisely is created.

Anstelle von Verbindungselementen, die als Zylinderbohrungen ausgebildet sind, können natürlich auch andere hochpräzise Verbindungselemente eingesetzt werden. Exakte Verbindungen werden etwa auch mit anderen passgenau-formschlüssigen Verbindungselementsystemen möglich, beispielsweise mit einer Kombination von Nutelementen und Federelementen, wobei es für die Funktion unerheblich ist, ob das Nutelement an dem Tabakkanalwandelement 1 und das Federelement an dem Kanalbasiselement 2 vorgesehen ist oder umgekehrt. Nicht geeignet sind hingegen unpräzise Verbindungen, etwa herkömmliche Schraubverbindungen, mit denen keine Verbindung mit Spiel im Mikrometerbereich erhalten werden könnte, sondern allenfalls von der Größenordnung einzelner Millimeter.Of course, other high-precision connecting elements can be used instead of connecting elements which are designed as cylinder bores. Exact connections are about possible with other precise-fit connection element systems, for example, with a combination of groove elements and spring elements, where it is irrelevant for the function, whether the Groove element is provided on the tobacco channel wall element 1 and the spring element on the channel base element 2 or vice versa. Not suitable, however, are inaccurate connections, such as conventional screw, with which no connection could be obtained with game in the micrometer range, but at most of the order of an individual millimeter.

Zur zusätzlichen Sicherung der Verbindung des Tabakkanalwandelements 1 an dem Kanalbasiselement 2 werden in der in Fig. 1 dargestellten Ausführung zusätzlich noch drei in den Bohrungen 15, 15' angeordnete Schrauben als Sicherungselemente verwendet, die in entsprechende Bohrungen an dem 25, 25' an Kanalbasiselement 2 eingreifen und so beide Elemente aneinander sichern. Insofern diese Sicherungselemente die Verbindung lediglich gegenüber solchen Zugbelastungen sichern, die parallel zu der Achse der Zylinderstifte und der Zylinderbohrungen 11, 12, 13, 14 gerichtet sind, jedoch nicht zu einer räumlichen Fixierung des Tabakkanalwandelements 1 an dem Kanalbasiselement 2 beitragen, können hierfür auch unpräzisere Verbindungsarten verwendet werden, etwa herkömmliche Schraubverbindungen. Stattdessen können natürlich auch andere geeignete Sicherungselemente zum Einsatz kommen wie etwa Sperrzapfen oder dergleichen.To additionally secure the connection of the tobacco channel wall element 1 to the channel base element 2 in the in Fig. 1 illustrated embodiment additionally three in the holes 15, 15 'arranged screws used as securing elements, which engage in corresponding holes on the 25, 25' on the channel base element 2 and thus secure both elements together. Insofar as these securing elements secure the connection only against such tensile loads, which are directed parallel to the axis of the cylindrical pins and the cylinder bores 11, 12, 13, 14, but do not contribute to a spatial fixation of the tobacco channel wall element 1 to the channel base element 2, this can also imprecise Connection types are used, such as conventional screw. Instead, of course, other suitable security elements may be used, such as locking pin or the like.

Um mit dem Tabakkanalwandelement 1 unterschiedliche Einbaulagen zu realisieren, weist dieses zwei unterschiedliche Verbindungsmittel auf und somit auch zwei Sätze an Verbindungselementen, nämlich die Zylinderbohrungen 11, 13 einerseits und die Zylinderbohrungen 12, 14 andererseits. Mit diesen zwei Verbindungsmitteln lassen sich zwei Einbaulagen verwirklichen. Soll das Tabakkanalwandelement 1 in einer ersten Einbaulage mit dem Kanalbasiselement 2 verbunden werden, so werden die Zylinderstifte in die äußeren beiden Zylinderbohrungen 11, 13 eingeführt. Auf diese Weise wird jedes Tabakkanalwandelement 1,1' so angeordnet, dass dessen Kanalinnenwandung einen konstanten Abstand von 4,5 mm zu der Tabakkanalmitte hat, woraus sich insgesamt eine Kanalbreite von 9,0 mm ergibt.In order to realize with the tobacco channel wall element 1 different mounting positions, this has two different connection means and thus two sets of connecting elements, namely the cylinder bores 11, 13 on the one hand and the cylinder bores 12, 14 on the other. Two mounting positions can be achieved with these two connection devices. If the tobacco channel wall element 1 is to be connected to the channel base element 2 in a first installation position, the cylindrical pins are inserted into the outer two cylinder bores 11, 13. In this way, each tobacco channel wall element 1,1 'is arranged so that its channel inner wall has a constant distance of 4.5 mm to the tobacco channel center, resulting in a total channel width of 9.0 mm.

Soll hingegen das Tabakkanalwandelement 1 in einer zweiten Einbaulage mit dem Kanalbasiselement 2 verbunden werden, so werden die Zylinderstifte in die inneren beiden Zylinderbohrungen 12, 14 eingeführt. Auf diese Weise wird das Tabakkanalwandelement 1 so angeordnet, dass dessen Kanalinnenwandung einen konstanten Abstand von 4,0 mm zu der Tabakkanalmitte hat, woraus sich eine Kanalbreite von insgesamt 8,0 mm ergibt.If, on the other hand, the tobacco channel wall element 1 is to be connected to the channel base element 2 in a second installation position, the cylindrical pins are inserted into the inner two cylinder bores 12, 14. That's how it works Tobacco channel wall element 1 is arranged so that its channel inner wall has a constant distance of 4.0 mm to the tobacco channel center, resulting in a channel width of 8.0 mm in total.

Die unterschiedlichen Abstände der Kanalinnenwandung von der Kanalmitte ergeben sich aus der Lage der Zylinderbohrungen 11, 13 bzw. 12, 14 auf der Basisseitenfläche des Tabakkanalwandelements 1 einerseits und der Lage der zu diesen komplementären Zylinderbohrungen 21, 23 bzw. 22, 24 des Kanalbasiselements 2 andererseits. So weisen vorliegend die Zylinderbohrungen 11, 13 des Tabakkanalwandelements 1 denselben Abstand von der oberen Kante der Kanalinnenwandung auf wie die Zylinderbohrungen 12, 14 des Tabakkanalwandelements 1, jedoch sind die Zylinderbohrungen 21, 23 des Kanalbasiselements 2 jeweils 0,5 mm weiter von der Kanalmitte entfernt angeordnet als die Zylinderbohrungen 22, 24 des Kanalbasiselements 2. Derselbe Effekt ließe sich natürlich auch dann erzielen, wenn die Zylinderbohrungen 11, 13 und die Zylinderbohrungen 12, 14 des Tabakkanalwandelements 1 unterschiedlich weit von der oberen Kante der Kanalinnenwandung entfernt vorgesehen wären, stattdessen aber die Zylinderbohrungen 21, 23 und die Zylinderbohrungen 22, 24 des Kanalbasiselements 2 einen gleichen Abstand von der Kanalmitte aufweisen würden, oder aber wenn sowohl die Zylinderbohrungen 11, 13 und die Zylinderbohrungen 12, 14 des Tabakkanalwandelements 1 als auch die Zylinderbohrungen 21, 23 und die Zylinderbohrungen 22, 24 des Kanalbasiselements 2 jeweils unterschiedliche Abstände aufweisen würden.The different distances of the channel inner wall of the channel center arise from the position of the cylinder bores 11, 13 and 12, 14 on the base side surface of the tobacco channel wall element 1 on the one hand and the position of these complementary cylinder bores 21, 23 and 22, 24 of the channel base element 2 on the other , Thus, in the present case, the cylinder bores 11, 13 of the tobacco channel wall element 1 at the same distance from the upper edge of the channel inner wall as the cylinder bores 12, 14 of the tobacco channel wall element 1, but the cylinder bores 21, 23 of the channel base element 2 are each 0.5 mm further away from the channel center Of course, the same effect could also be achieved if the cylinder bores 11, 13 and the cylinder bores 12, 14 of the tobacco channel wall element 1 were provided at different distances from the upper edge of the channel inner wall, but instead the Cylinder bores 21, 23 and the cylinder bores 22, 24 of the channel base member 2 would have an equal distance from the channel center, or if both the cylinder bores 11, 13 and the cylinder bores 12, 14 of the tobacco channel wall element 1 and the cylinder bores 21, 23 and the cylinder bores 22, 24 of the Kanalba Siselements 2 would each have different distances.

Um unterschiedliche Einbaulagen zu erzielen werden also entweder die beiden äußeren Zylinderbohrungen 11, 13 oder aber die beiden inneren Zylinderbohrungen 12, 14 zum Verbinden des Tabakkanalwandelements 1 mit dem Kanalbasiselement 2 verwendet. Dadurch, dass der erste Abstand, also der Abstand zwischen Zylinderbohrung 11 und Zylinderbohrung 13, von dem zweiten Abstand verschieden ist, also dem Abstand zwischen Zylinderbohrung 12 und Zylinderbohrung 14, wird verhindert, dass versehentlich eine schiefe Ausrichtung des Tabakkanalwandelements 1 erfolgt, die etwa dann eintreten könnte, wenn das Tabakkanalwandelement 1 über Zylinderbohrung 11 in Kombination mit Zylinderbohrung 14 oder über Zylinderbohrung 12 in Kombination mit Zylinderbohrung 13 mit dem Kanalbasiselement 2 verbunden werden könnte.In order to achieve different mounting positions so either the two outer cylinder bores 11, 13 or the two inner cylinder bores 12, 14 are used for connecting the tobacco channel wall element 1 with the channel base element 2. The fact that the first distance, so the distance between the cylinder bore 11 and cylinder bore 13, is different from the second distance, ie the distance between the cylinder bore 12 and the cylinder bore 14, prevents accidentally an oblique orientation of the tobacco channel wall element 1 takes place, which is about could occur when the tobacco channel wall element 1 via cylinder bore 11 in Combination with cylinder bore 14 or via cylinder bore 12 in combination with cylinder bore 13 could be connected to the channel base element 2.

Vorliegend ist der erste Abstand also größer als der zweite Abstand gewählt und derart an der Basisseitenfläche des Tabakkanalwandelements 1 angeordnet, dass sich die Zylinderbohrungen 12, 14 des zweiten Verbindungsmittels zwischen den Zylinderbohrungen 11, 13 des ersten Verbindungsmittels befinden. Da der größere Abstand der Zylinderbohrungen 11, 13 also auch der Einbaulage mit der größeren Kanalbreite entspricht, kann das mit dem Umbau der Zigarettenstrangmaschinen betraute Personal auf diese Weise intuitiv erfassen, welche Zylinderbohrungen für eine erwünschte Einbaulage zu verwenden sind.In the present case, the first distance is thus chosen larger than the second distance and arranged on the base side surface of the tobacco channel wall element 1 such that the cylinder bores 12, 14 of the second connection means are located between the cylinder bores 11, 13 of the first connection means. Since the greater distance between the cylinder bores 11, 13 also corresponds to the installation position with the larger channel width, entrusted with the conversion of cigarette rod machines staff can intuitively grasp in this way, which cylinder bores are to be used for a desired installation position.

Soll ein Tabakkanalwandelement für mehr als zwei Einbaulagen geeignet sein, so können darüber hinaus natürlich auch noch weitere Verbindungsmittel an dessen Basisseitenfläche vorgesehen sein, die in Weiterbildung des vorliegenden Ausfiihrungsbeispiels ebenfalls aus Sätzen an Zylinderlochbohrungen bestehen könnten.If a tobacco channel wall element is to be suitable for more than two installation positions, it is of course also possible to provide further connection means on its base side surface which, in a further development of the present exemplary embodiment, could also consist of sets of cylinder bore holes.

Ferner ist es selbstverständlich auch möglich, dass jedes Verbindungsmittel mehr als zwei Zylinderbohrungen umfasst. Durch eine Verwendung weiterer Verbindungselemente wäre es möglich, die ohnehin schon hohe Stabilität der Verbindung zwischen dem Tabakkanalwandelement 1 und dem Kanalbasiselement 2 sogar noch weiter zu erhöhen. In diesem Fall wäre darauf zu achten, dass jeweils der Abstand zwischen den beiden äußeren Zylinderbohrungen jedes Verbindungsmittels unterschiedlich groß ausfällt, um die intuitive Erfassbarkeit der Einbaulagen zu gewährleisten. Überdies können das erste Verbindungsmittel und das zweite Verbindungsmittel auch unterschiedliche Anzahlen an Verbindungselementen aufweisen. Dabei können einzelne Verbindungselemente des einen Verbindungsmittels mit einzelnen Verbindungselementen eines anderen Verbindungsmittels nicht nur verschieden, sondern auch identisch sein. Dies betrifft insbesondere den Fall, dass bei einem ersten Verbindungsmittel mit mehr als zwei Verbindungselementen innere Verbindungselemente, die jeweils zwischen den äußeren Verbindungselementen angeordnet sind, identisch sein können mit inneren oder äußeren Verbindungselementen eines zweiten Verbindungsmittels.Furthermore, it is of course also possible that each connecting means comprises more than two cylinder bores. By using further connecting elements, it would be possible to increase the already high stability of the connection between the tobacco channel wall element 1 and the channel base element 2 even further. In this case, it should be ensured that in each case the distance between the two outer cylinder bores of each connecting means varies in size to ensure the intuitive detectability of the mounting positions. Moreover, the first connection means and the second connection means may also have different numbers of connection elements. In this case, individual connecting elements of one connecting means with individual connecting elements of another connecting means may not only be different but also identical. This applies in particular to the case that in a first connecting means with more than two connecting elements inner connecting elements, which are each arranged between the outer connecting elements, may be identical to inner or outer connecting elements of a second connecting means.

In Fig. 2 ist ein Kanalbasiselement 2 dargestellt, das für eine Doppelstrangmaschine ausgelegt ist und daher für zwei verschiedene Tabakkanäle eingerichtet ist. Die jeweiligen einzelnen Kanalbasiselemente der beiden Systeme sind hierbei in einem einzigen Doppelkanalbasiselement 2 integriert. Das gemeinsame Kanalbasiselement 2 wird hierbei mit zwei Sätzen Tabakkanalwandelementen passgenau verbunden, also mit vier einzelnen Tabakkanalwandelementen, die jeweils in unterschiedlichen Einbaulagen befestigt werden können. Eine derartige Tabakkanalanordnung umfasst somit zwei Tabakkanalsysteme mit je einem Tabakkanal. Der Übersichtlichkeit halber beschränkt sich die Beschreibung vorliegend auf ein einziges Tabakkanalsystem, nämlich das vordere; für das hintere Tabakkanalsystem gilt natürlich Entsprechendes.In Fig. 2 a channel base element 2 is shown, which is designed for a double-strand machine and is therefore adapted for two different tobacco channels. The respective individual channel base elements of the two systems are in this case integrated in a single double-channel base element 2. The common channel base element 2 is in this case accurately connected to two sets of tobacco channel wall elements, ie with four individual tobacco channel wall elements, which can each be mounted in different mounting positions. Such a tobacco channel arrangement thus comprises two tobacco channel systems, each with a tobacco channel. For the sake of clarity, the description herein is limited to a single tobacco channel system, namely the front; Of course, the same applies to the rear tobacco channel system.

Jedes Tabakkanalsystem verfügt über ein eigenes Fördermittel, um den Tabakstrang in Kanalrichtung aus der Strangbildungszone zu transportieren; dieses ist als Unterdrucktabakförderungsmittel ausgebildet (in Fig. 2 nicht dargestellt). Jedes Unterdrucktabakförderungsmittel umfasst ein Saugband, dass parallel zu der innerhalb des Kanals liegenden Kanalinnenwandung nahe der Unterseite des Kanalbasiselements 2 entlangläuft, sowie Bandführungselemente. Letztere können je nach Ausgestaltung des Sauggurtes unbeweglich oder beweglich ausgebildet sein, etwa als Rollenauflage. Um ein vollflächiges Ansaugen der Tabakfasern an dem Sauggurt zu ermöglichen, weist das Kanalbasiselement 2 Saugluftöffnungen 27 auf, über die Ansaugluft aus dem Tabakkanal durch das Saugband hindurch in einen Unterdruckbereich gelangen kann.Each tobacco channel system has its own conveying means for transporting the tobacco rod in channel direction out of the strand formation zone; this is designed as a vacuum tobacco conveying means (in Fig. 2 not shown). Each vacuum tobacco conveying means comprises a suction belt running parallel to the channel inside wall located near the underside of the channel base member 2, and tape guide members. The latter can be immobile or movable depending on the design of the suction belt, for example as a roller support. In order to enable a full-surface suction of the tobacco fibers on the suction belt, the channel base element 2 on suction air openings 27, can pass through the intake air from the tobacco channel through the suction belt into a negative pressure region.

Das Kanalbasiselement 2 hat an der unteren Seite eine Kanalinnenwandung, die mit den Basisseitenflächen der Tabakkanalwandelemente 1, 1' passgenau verbunden werden kann. Dazu weist das Kanalbasiselement 2 an der Kanalinnenwandung ein erstes Verbindungsmittel und ein zweites Verbindungsmittel auf. Das erste Verbindungsmittel umfasst zur Verbindung mit einem ersten vorderen Tabakkanalwandelement 1 einen Satz Zylinderbohrungen 21, 23 als erstes Verbindungselement sowie einen weiteren Satz Zylinderbohrungen 22, 24 als zweites Verbindungselement. Zur Verbindung mit einem zweiten hinteren Tabakkanalwandelement 1' weist das Kanalbasiselement 2 zudem einen Satz Zylinderbohrungen 21', 23' als erstes Verbindungselement sowie einen weiteren Satz Zylinderbohrungen 22', 24' als zweites Verbindungselement auf.The channel base element 2 has on the lower side of a channel inner wall, which can be accurately connected to the base side surfaces of the tobacco channel wall elements 1, 1 '. For this purpose, the channel base element 2 on the channel inner wall on a first connecting means and a second connecting means. The first connecting means comprises, for connection to a first front tobacco channel wall element 1, a set of cylinder bores 21, 23 as a first connecting element and a further set of cylinder bores 22, 24 as a second connecting element. For connection to a second rear tobacco channel wall element 1 ', the channel base element 2 also has a set of cylinder bores 21', 23 'as a first connecting element and a further set of cylinder bores 22', 24 'as a second connecting element.

Die Zylinderbohrung 21 ist - wie obenstehend beschrieben - zum Verbinden des Kanalbasiselements 2 mit der Zylinderbohrung 11 des ersten Tabakkanalwandelements 1 vorgesehen, die Zylinderbohrung 22 ist zum Verbinden des Kanalbasiselements 2 mit der Zylinderbohrung 12 des ersten Tabakkanalwandelements 1 vorgesehen, die Zylinderbohrung 23 ist zum Verbinden des Kanalbasiselements 2 mit der Zylinderbohrung 13 des ersten Tabakkanalwandelements 1 vorgesehen und die Zylinderbohrung 24 ist zum Verbinden des Kanalbasiselements 2 mit der Zylinderbohrung 14 des ersten Tabakkanalwandelements 1 vorgesehen.The cylinder bore 21 is provided as described above for connecting the channel base member 2 to the cylinder bore 11 of the first tobacco channel wall member 1, the cylinder bore 22 is provided for connecting the channel base member 2 to the cylinder bore 12 of the first tobacco channel wall member 1, the cylinder bore 23 is for connecting the Channel base member 2 is provided with the cylinder bore 13 of the first tobacco channel wall member 1 and the cylinder bore 24 is provided for connecting the channel base member 2 with the cylinder bore 14 of the first tobacco channel wall element 1.

Entsprechend ist die Zylinderbohrung 21' ist zum Verbinden des Kanalbasiselements 2 mit der Zylinderbohrung 11' des zweiten Tabakkanalwandelements 1' vorgesehen, die Zylinderbohrung 22' zum Verbinden des Kanalbasiselements 2 mit der Zylinderbohrung 12' des zweiten Tabakkanalwandelements 1' vorgesehen, die Zylinderbohrung 23' zum Verbinden des Kanalbasiselements 2 mit der Zylinderbohrung 13' des zweiten Tabakkanalwandelements 1' vorgesehen und die Zylinderbohrung 24' zum Verbinden des Kanalbasiselements 2 mit der Zylinderbohrung 14' des zweiten Tabakkanalwandelements 1' vorgesehen.Accordingly, the cylinder bore 21 'is provided for connecting the channel base member 2 to the cylinder bore 11' of the second tobacco channel wall member 1 ', the cylinder bore 22' for connecting the channel base member 2 to the cylinder bore 12 'of the second tobacco channel wall member 1' provided, the cylinder bore 23 'to Connecting the channel base member 2 with the cylinder bore 13 'of the second tobacco channel wall element 1' provided and the cylinder bore 24 'for connecting the channel base member 2 with the cylinder bore 14' of the second tobacco channel wall element 1 'is provided.

Diese Ausbildung beinhaltet daher ferner, dass die Zylinderbohrungen 21, 22, 23, 24 des Kanalbasiselements 2 komplementär zu den jeweiligen Zylinderbohrungen 11, 12, 13, 14 des entsprechenden Tabakkanalwandelements 1 eingerichtet sind, so dass sich die komplementären Zylinderbohrungen jeweils hinsichtlich ihrer Anordnung und Lage auf den jeweiligen Elementen entsprechen.Therefore, this design further includes that the cylinder bores 21, 22, 23, 24 of the channel base member 2 are arranged complementary to the respective cylinder bores 11, 12, 13, 14 of the corresponding tobacco channel wall element 1, so that the complementary cylinder bores each with respect to their arrangement and location correspond to the respective elements.

Somit wird die Einbaulage der Tabakkanalwandelemente 1, 1' mittels der jeweils komplementär eingerichteten Zylinderbohrungen 11. 12, 13, 14, 11', 12', 13', 14' der Tabakkanalwandelemente 1,1' einerseits und der Zylinderbohrungen 21, 22, 23, 24, 21', 22', 23', 24' des Kanalbasiselements 2 andererseits festgelegt. Die Tabakkanalwandelemente 1, 1' sind daher parallel zueinander und beabstandet voneinander ausrichtbar, wobei die Kanalbreite, also die Entfernung zwischen der Kanalinnenwandung des ersten Tabakkanalwandelements 1 und der Kanalinnenwandung des zweiten Tabakkanalwandelements 1' wählbar ist.Thus, the installation position of the tobacco channel wall elements 1, 1 'by means of the respective complementary cylinder bores 11. 12, 13, 14, 11', 12 ', 13', 14 'of the tobacco channel wall elements 1,1' on the one hand and the cylinder bores 21, 22, 23rd , 24, 21 ', 22', 23 ', 24' of the channel base member 2 on the other hand. The tobacco channel wall elements 1, 1 'are therefore parallel to each other and spaced from each other alignable, the channel width, ie the distance between the channel inner wall of the first tobacco channel wall element 1 and the channel inner wall of the second tobacco channel wall element 1' is selectable.

Natürlich ist es auch möglich, die Breite des Tabakkanals dadurch zu ändern, dass lediglich jeweils nur die Einbaulage eines einzigen Tabakkanalwandelements anstelle der Einbaulage beider Tabakkanalwandelemente geändert wird. Da sich bei einer derartigen einseitigen Anpassung jedoch auch die Lage der Kanalmitte und damit auch die Mitte des Tabakstrangs verschiebt, erfordert eine derartige einseitige Anpassung einen weiteren Anpassungsschritt, bei dem die Lage der Strangbildungszone relativ zu den weiteren Verarbeitungszonen der Zigarettenstrangmaschine verändert wird.Of course, it is also possible to change the width of the tobacco channel in that only only the installation position of a single tobacco channel wall element instead of the installation position of both tobacco channel wall elements is changed. However, since in such a one-sided adjustment, the position of the channel center and thus also the middle of the tobacco rod moves, such a one-sided adjustment requires a further adaptation step, in which the position of the strand formation zone is changed relative to the other processing zones of the cigarette rod machine.
