Die Erfindung betrifft eine Maschine der Tabak verarbeitenden Industrie mit mehreren Saugeinrichtungen zum Erzeugen von Unterdruck an Arbeitsorganen der Maschine. Ferner betrifft die Erfindung eine Verwendung von mehreren Saugeinrichtungen an einer Maschine der Tabak verarbeitenden Industrie sowie ein Verfahren zum Betreiben einer Maschine der Tabak verarbeitenden Industrie mit mehreren mit Unterdruck beaufschlagbaren Arbeitsorganen.The invention relates to a machine of the tobacco processing industry with a plurality of suction devices for generating negative pressure to working organs of the machine. Furthermore, the invention relates to a use of a plurality of suction devices on a machine of the tobacco-processing industry and a method for operating a machine of the tobacco-processing industry with a plurality of pressurizable working members.

Unter der Bezeichnung "MAX" ist beispielsweise eine Filteransetzmaschine der Patentanmelderin als Maschine der Tabak verarbeitenden Industrie bekannt.By the term "MAX", for example, a filter attachment of the patent applicant is known as a machine of the tobacco processing industry.

Als Filteransetzmaschine wird eine Vorrichtung bzw. Maschine zur Herstellung von Filterzigaretten verstanden mit Mitteln zur Aufnahme von Tabakstäben doppelter Länge, mit Mitteln zum Schneiden dieser doppeltlangen Tabakstöcke in Tabakstöcke einfacher Länge, mit Mitteln zum Einbringen von Filterstopfen doppelter Länge zwischen die Tabakstöcke einfacher Länge, mit Mitteln zum Verbinden des doppeltlangen Filterstopfens mit den beiden Tabakstöcken einfacher Länge durch Umhüllen mit einem Belagpapierblättchen, das mittels einer Schneideinrichtung von einem zugeführten Belagpapierstreifen abgetrennt wird, mit Mitteln zum nachfolgenden Ausführen eines Trennschnitts durch den doppeltlangen Filterstopfen, so dass Filterzigaretten normaler Gebrauchslänge entstehen.As a filter attachment machine is a device or machine for the production of filter cigarettes understood with means for receiving tobacco rods of double length, with means for cutting this double-length tobacco sticks in tobacco sticks of simple length, with means for introducing filter plug of double length between the tobacco sticks of simple length, with means for connecting the double-length filter plug with the two tobacco sticks simple length by wrapping with a tipping paper leaflet separated by a cutter from a supplied tipping paper strip with means for subsequently performing a cut through the double-length filter plug so that filter cigarettes of normal use length are formed.

Es ist bei Maschinen der Tabak verarbeitenden Industrie umfassend Fördervorrichtungen mit wenigstens einer Trommel üblich, Produkte der Tabak verarbeitenden Industrie wie Zigaretten, Filterbelagblättchen und ähnlichem in Mulden bzw. auf Mulden von Trommeln bzw. auf Trommeln durch Halteluft bzw. Saugluft beim Transport bzw. beim Fördern dieser Artikel zu halten. Hierzu wird, wie beispielsweise in DE 101 42 181 A1 der Anmelderin offenbart, maschinenseitig im Inneren der Fördertrommel ein Unterdruck zur Verfügung gestellt und der Innenraum der Trommel mit einer maschinenseitigen Ansaugvorrichtung verbunden. Durch den im Innenraum vorherrschenden Unterdruck werden während der Drehung der Trommel an einer bestimmten Stelle Zigaretten bzw. Artikel der Tabak verarbeitenden Industrie angesogen und aufgenommen und/oder von einer anderen Transporteinrichtung übernommen. Infolge des Ansaugens und des Unterdrucks im Innenraum haften die Zigarettenkomponenten in den Aufnahmen bzw. an den Stellen, an denen der Unterdruck herrscht bzw. die Halteluft angreift.It is common in machines of the tobacco processing industry comprising conveying devices with at least one drum, products of the tobacco processing industry such as cigarettes, filter cover sheets and the like in troughs or on troughs of drums or on drums by holding air or suction during transport or during conveying to keep this article. For this purpose, such as in DE 101 42 181 A1 The applicant discloses, provided on the machine side inside the conveyor drum, a negative pressure and the interior of the drum connected to a machine-side intake. As a result of the negative pressure prevailing in the interior, cigarettes or articles of the tobacco-processing industry are sucked in and picked up at a certain point during the rotation of the drum and / or taken over by another transport device. As a result of the suction and the negative pressure in the interior of the cigarette components adhere to the recordings or at the points where the negative pressure prevails or attacks the holding air.

Um die Positionen zu definieren, an denen eine entsprechende Halteluft vorherrschen soll, dient üblicherweise ein Steuerkörper oder ein Steuerring, um den der Trommelkörper selbst rotiert. Hierzu sei beispielsweise auf DE 42 15 060 A1 , die GB 225 98 44 A entspricht, verwiesen. In diesem Dokument ist eine Rolltrommel offenbart, die ausgebildet ist, um Zigaretten-Filter-Gruppen mittels Belagblättchen zu verbinden. In dieser Druckschrift ist außerdem ein pneumatisches Aussonderungsmittel zum gezielten Entfernen von unerwünschten, insbesondere unvollständigen, Komponentengruppen vorgesehen.In order to define the positions at which a corresponding holding air is to prevail, usually serves a control body or a control ring, around which the drum body rotates itself. For example, be on DE 42 15 060 A1 , the GB 225 98 44 A corresponds, directed. In this document, a roller drum is disclosed, which is adapted to connect cigarette filter groups by means of covering sheets. In this document, a pneumatic separation means for targeted removal of unwanted, especially incomplete, component groups is also provided.

Weiterhin ist aus EP-A-1 637 044 eine Fördervorrichtung der Tabak verarbeitenden Industrie bekannt, wobei die Fördervorrichtung eine Trommel aufweist. Die Trommel umfasst Halteelemente zur Aufnahme von Artikeln der Tabak verarbeitenden Industrie, wobei je Halteelement wenigstens ein Halteluftkanal vorgesehen ist, der in das Halteelement reicht, wobei der Halteluftkanal wenigstens zeitweise oder wenigstens abschnittsweise mit einer Saugluftquelle verbunden ist. Zwischen der Saugluftquelle und den Haltekanälen ist dabei ein Saugluftpufferraum vorgesehen.Furthermore, it is off EP-A-1 637 044 a conveying device of the tobacco processing industry, wherein the conveying device comprises a drum. The drum comprises holding elements for receiving articles of the tobacco-processing industry, wherein each holding element is provided at least one holding air duct, which extends into the holding element, wherein the holding air duct is at least temporarily or at least partially connected to a suction air source. In this case, a Saugluftpufferraum is provided between the suction air source and the holding channels.

Ferner ist aus diesem Dokument eine Maschine der Tabak verarbeitenden Industrie bekannt, die mehrere Saugluftpufferräume aufweist, wobei die Saugluftpufferräume jeweils einer Trommel zugeordnet sind.Furthermore, from this document, a machine of the tobacco processing industry is known, which has a plurality Saugluftpufferräume, wherein the Saugluftpufferräume are each associated with a drum.

Ausgehend von diesem Stand der Technik besteht die Aufgabe der vorliegenden Erfindung darin, die Versorgung mit Unterdruck an Arbeitsorgangen bzw. Förderorganen einer Maschine der Tabak verarbeitenden Industrie oder einer Anlage der Tabak verarbeitenden Industrie zu verbessern.Based on this prior art, the object of the present invention is to improve the supply of negative pressure at Arbeitsorgangen or conveying organs of a machine of the tobacco processing industry or a plant of the tobacco-processing industry.

Die Aufgabe wird gelöst durch eine Maschine der Tabak verarbeitenden Industrie mit mehreren Saugeinrichtungen zum Erzeugen von Unterdruck an Arbeitsorganen der Maschine, die dadurch weitergebildet wird, dass zwei oder mehr als zwei Saugeinrichtungen an ihren jeweiligen Saugseiten an einen gemeinsamen Unterdruckversorgungskanal parallel angeschlossen sind, so dass mehrere mit Unterdruck beaufschlagbare Arbeitsorgane der Maschine über den gemeinsamen Unterdruckversorgungskanal mit Unterdruck, insbesondere parallel, beaufschlagt werden oder sind.The object is achieved by a machine of the tobacco processing industry with a plurality of suction devices for generating negative pressure on working organs of the machine, which is further developed by having two or more than two suction devices are connected in parallel at their respective suction sides to a common vacuum supply channel, so that a plurality of under pressure acted upon working members of the machine via the common vacuum supply channel with negative pressure, in particular, are applied in parallel, or are.

Gemäß dem Stand der Technik werden die Arbeitsorgane bzw. Fördertrommeln beispielsweise an einer Filteransetzmaschine mit Unterdruck beaufschlagt, wobei mehrere Fördertrommeln jeweils mit einer Saugeinrichtung verbunden sind, die Unterdruck an den Fördertrommeln zum Halten von stabförmigen Artikeln der Tabak verarbeitenden Industrie in den Mulden der Fördertrommel bereitstellt. Hierbei sind den Saugeinrichtungen jeweils mehrere Fördertrommeln direkt zugeordnet.According to the prior art, the working organs or conveyor drums are subjected, for example, to a filter attachment machine with negative pressure, wherein a plurality of conveyor drums are each connected to a suction device which provides negative pressure on the conveyor drums for holding rod-shaped articles of the tobacco processing industry in the wells of the conveyor drum. Here, the suction devices are each assigned directly to several conveyor drums.

Demgegenüber beruht die Erfindung auf dem Gedanken, dass die Saugeinrichtungen bzw. Ventilatoren parallel an einen zentralen und gemeinsamen Unterdruckversorgungskanal angeschlossen werden, an dem auch die Fördertrommeln als Arbeitsorgane parallel angeschlossen sind, so dass an den Fördertrommeln Unterdruck zum Halten der stabförmigen Artikel auf den Fördertrommeln bereitsteht. Der Vorteil des gemeinsamen Unterdruckversorgungskanals besteht darin, dass bei plötzlich auftretenden Luftstromänderungen bzw. Volumenstromänderungen an einer oder mehreren Fördertrommeln, z.B. bei Entnahme von stabförmigen Artikeln von einer Fördertrommel, nur ein relativ geringer Druckabfall an den betroffenen Fördertrommeln bewirkt wird, da der Druckeinbruch an den Fördertrommeln bzw. an einem Modul mit den Fördertrommeln nunmehr über mehrere Saugeinrichtungen bzw. Ventilatoren in Parallelschaltung mit Unterdruck versorgt wird.In contrast, the invention is based on the idea that the suction devices or fans are connected in parallel to a central and common vacuum supply channel to which the conveyor drums are connected in parallel as working organs, so that is ready to hold the rod-shaped article on the conveyor drums on the conveyor drums , The advantage of the common negative pressure supply channel is that in the event of sudden changes in air flow or volume flow changes to one or more conveyor drums, e.g. When removing rod-shaped articles from a conveyor drum, only a relatively small pressure drop is effected on the conveyor drums concerned, since the pressure drop on the conveyor drums or on a module with the conveyor drums is now supplied via several suction devices or fans in parallel with negative pressure.

Darüber hinaus ist es aufgrund des gemeinsamen Unterdruckversorgungskanals möglich, dass die Kapazität der Unterdruckversorgung der Maschine bzw. der Anlage auf einfache Weise modular erweiterbar ist. Beispielsweise wenn eine Filteransetzmaschine um ein weiteres Modul erweitert wird, wird die für das Modul vorgesehene Saugeinrichtung ebenfalls an den gemeinsamen und zentralen Unterdruckversorgungskanal der Maschine angeschlossen.In addition, it is due to the common vacuum supply channel possible that the capacity of the vacuum supply of the machine or the system is easily expandable in a modular manner. For example, if a filter attachment machine is extended by a further module, the suction device provided for the module is also connected to the common and central vacuum supply channel of the machine.

Im Rahmen der Erfindung wird unter einer Maschine der Tabak verarbeitenden Industrie eine Strangmaschine oder eine Filteransetzmaschine oder eine weitere Herstellungsmaschine von Produkten der Tabak verarbeitenden Industrie verstanden. Im Rahmen der Erfindung wird auch unter einer Maschine der Tabak verarbeitenden Industrie eine Anlage verstanden, die aus einer Kombination von mehreren Einzelmaschinen gebildet ist.In the context of the invention, a machine of the tobacco-processing industry is understood to mean an extrusion machine or a filter attachment machine or a further production machine of products of the tobacco-processing industry. In the context of the invention, a machine of the tobacco-processing industry is understood to mean a system which is formed from a combination of several individual machines.

In einer bevorzugten Ausführungsform weist die Maschine mehrere, insbesondere separate, Maschinenfunktionsmodule auf, die jeweils wenigstens ein oder mehrere mit Unterdruck beaufschlagbare Arbeitsorgane bzw. Förderorgane oder dergleichen aufweisen, wobei die Arbeitsorgane der Maschinenfunktionsmodule über den gemeinsamen Unterdruckversorgungskanal mit Unterdruck beaufschlagt werden. Dadurch ist es möglich, eine Maschine mit mehreren Funktionsmodulen modular aufzubauen bzw. zu errichten, wobei die für die Arbeitsorgane der Maschinenfunktionsmodule jeweils vorgesehenen Saugeinrichtungen an dem gemeinsamen Unterdruckversorgungskanal angeschlossen werden, wobei die Saugeinrichtung parallel zu den bereits vorhandenen Saugeinrichtungen für die gesamte Maschine parallel angeschlossen ist.In a preferred embodiment, the machine has several, in particular separate, machine function modules, each having at least one or more acted upon by vacuum working organs or conveying members or the like, wherein the working organs of the machine function modules are acted upon by the common vacuum supply channel with negative pressure. This makes it possible to construct a modular machine with multiple functional modules, wherein the appropriate for the working organs of the machine function modules suction devices are connected to the common vacuum supply channel, wherein the suction device is connected in parallel to the already existing suction for the entire machine in parallel ,

Darüber hinaus ist es in einer Ausgestaltung vorteilhaft, dass die parallel an den gemeinsamen Unterdruckversorgungskanal angeschlossenen Saugeinrichtungen zwischen den Betriebspunkten der Maschine stabile Druck/Volumenstrom-Kennlinien aufweisen. Dadurch wird ein dauerhafter und sicherer Betrieb der Maschine bzw. der Anlage während der Produktion gewährleistet. Die Betriebspunkte ergeben sich durch die Schnittpunkte der Anlagenkennlinie bzw. Maschinenkennlinie mit den Ventilatorkennlinien im Druck/Volumenstrom-Diagramm.In addition, it is advantageous in one embodiment that the suction devices connected in parallel to the common vacuum supply channel between the operating points of the Machine have stable pressure / flow characteristics. This ensures a permanent and safe operation of the machine or system during production. The operating points result from the intersections of the system characteristic curve or machine characteristic curve with the fan characteristic curves in the pressure / volumetric flow diagram.

Ferner ist es von Vorteil, dass eine bzw. die Summenkennlinie der Druck/Volumenstrom-Kennlinien der parallel an den gemeinsamen Unterdruckversorgungskanal angeschlossenen Saugeinrichtungen zwischen den Betriebspunkten der Maschine stabil ist. Vorzugsweise sind die Druck/Volumenstrom-Kennlinien der Saugeinrichtungen, die an den gemeinsamen Unterdruckversorgungskanal angeschlossen sind, im Wesentlichen gleich oder identisch, so dass gleiche bzw. baugleiche Ventilatoren als Saugeinrichtungen verwendet werden, die ein gleiches Unterdruckniveau bereitstellen.Furthermore, it is advantageous that one or the sum characteristic of the pressure / volume flow characteristics of the suction devices connected in parallel to the common vacuum supply channel is stable between the operating points of the machine. Preferably, the pressure / volume flow characteristics of the suction devices connected to the common vacuum supply channel are substantially equal or identical, so that identical or identical fans are used as suction devices that provide a same level of negative pressure.

Insbesondere entspricht die Summenkennlinie der Druck/Volumenstromkennlinien der parallel arbeitenden Saugeinrichtungen bzw. dem Gebläse oder den Ventilatoren in ihrer Summe in etwa der Kennlinie eines einzelnen großen Gebläses für die gesamte Maschine oder Anlage.In particular, the sum characteristic of the pressure / volume flow characteristics of the suction devices operating in parallel or the blower or the fans in their sum approximately corresponds to the characteristic curve of a single large blower for the entire machine or plant.

Darüber hinaus zeichnet sich eine Weiterbildung der Maschine dadurch aus, dass die an den gemeinsamen Unterdruckversorgungskanal parallel angeschlossenen Saugeinrichtungen, insbesondere Ventilatoren, Druck/Volumenstrom-Kennlinien ohne Scheitelpunkte und/oder ohne Wendepunkte aufweisen.In addition, a development of the machine is characterized by the fact that the suction devices, in particular fans, which are connected in parallel to the common vacuum supply channel, in particular fans, have pressure / volume flow characteristics without apexes and / or without inflection points.

From the cutting drum 20, the tobacco sticks simple use length are transferred to a spreading drum 23, on which the cut tobacco rod pairs are longitudinally spaced apart or spread apart. Subsequently, the longitudinally-spaced tobacco rod pairs are transported via a conveyor drum 24 to the compilation drum 21.

Auf ihrem Förderweg zu einer Zusammenstelltrommel 21 werden die Tabakstöcke doppelter Gebrauchslänge geschnitten und längsaxial gespreizt. Auf der Zusammenstelltrommel 21 werden über eine weitere Trommelanordnung M doppeltlange Filterstopfen transportiert, die jeweils zwischen zwei längsaxial beabstandete Tabakstöcke eingefügt werden. Hierdurch wird auf der Zusammenstelltrommel 21 eine Folge von queraxial hintereinander angeordneten Tabakstock-Filterstopfen-Tabakstock-Gruppen gebildet.On their conveyor to a compilation drum 21, the tobacco rods are cut twice the length of use and spread longitudinally axially. On the assembly drum 21 are transported over a further drum assembly M double-length filter plugs, which are inserted between two longitudinally spaced tobacco rods. As a result, a sequence of tobacco rod filter plug tobacco rod groups arranged transaxially behind one another is formed on the assembly drum 21.

Um doppeltlange Filterstopfen zwischen die längsaxial beabstandeten Tabakstockpaare auf der Zusammenstelltrommel einzulegen bzw. anzuordnen, verfügt die Trommelanordnung M über Fördertrommeln 14, 15, 16 und 17, auf denen Filterstäbe, die in Filterstopfen doppelter Länge geschnitten werden, sowie Filterstopfen doppelter Länge queraxial zu der Zusammenstelltrommel 21 gefördert werden.To place double-length filter plugs between the longitudinally spaced tobacco rod pairs on the assembly drum, the drum assembly M has conveyor drums 14, 15, 16 and 17 on which filter rods cut into double length filter plugs and filter plugs twice length transversely to the assembly drum 21 are promoted.

Die doppeltlangen Filterzigaretten werden nachfolgend an eine Fördertrommel 28 und weiter nachfolgend an eine weitere Fördertrommel 29 übergeben und für den weiteren Bearbeitungsprozess an einer Filteransetzmaschine bereitgestellt.The double-length filter cigarettes are subsequently transferred to a conveyor drum 28 and further below to a further conveyor drum 29 and provided for the further processing process on a filter attachment machine.

Von der Fördertrommel 29 werden die doppeltlangen Filterzigaretten über eine Fördertrommel 30 zu einer Schneidtrommel 31 gefördert, an der ein Schneidmesser 32 angeordnet ist, welches aus den doppeltlangen Filterzigaretten durch einen mittigen Trennschnitt Filterzigaretten einfacher Gebrauchslänge herstellt.From the conveyor drum 29, the double-length filter cigarettes are conveyed via a conveyor drum 30 to a cutting drum 31, on which a cutting blade 32 is arranged, which produces from the double-length filter cigarettes by a central separating cut filter cigarettes simple use length.

Die Filterzigaretten werden anschließend von der Schneidtrommel 31 an eine Spreiztrommel 33 übergeben. Auf der Spreiztrommel 33 werden die Filterzigarettenpaare längsaxial voneinander beabstandet und anschließend an eine erste Prüftrommel 34 übergeben. An der Prüftrommel 34 ist ein erstes Prüforgan 44 angeordnet, welches die Filterzigaretten einer ersten Prüfung, z.B. einer Kopfendenprüfung, unterzieht.The filter cigarettes are then transferred from the cutting drum 31 to a spreading drum 33.

Anhand des Ausführungsbeispiels in Fig. 1 soll nachfolgend die Bereitstellung von Unterdruck bzw. Saugluft an den Förderorganen bzw. der Fördertrommel beispielhaft erläutert werden, wobei die bzw. Fördertrommeln der Trommelanordnung T, bestehend aus den Fördertrommeln 18, 19, 20, 21, 23, 24 und die Trommeln 14, 15, 16, 17 der Trommelanordnung M für die Zuführung von Filterstopfen doppelter Länge und die Fördertrommeln 12, 22, 26, 27, 28, 29 sowie die Fördertrommeln 30, 31, 33, 34, 35 des nachfolgenden Fördermoduls jeweils direkt mit einem einzigen Ventilator 50 verbunden sind, um Saugluft an den Fördertrommeln bereitzustellen, was aus Gründen der Übersichtlichkeit nur schematisch angedeutet ist.Based on the embodiment in Fig. 1 the supply of negative pressure or suction air to the conveyor members or the conveyor drum is to be explained below by way of example, wherein the or conveyor drums of the drum assembly T, consisting of the conveyor drums 18, 19, 20, 21, 23, 24 and the drums 14, 15th , 16, 17 of the drum assembly M for the supply of filter plugs double length and the conveyor drums 12, 22, 26, 27, 28, 29 and the conveyor drums 30, 31, 33, 34, 35 of the subsequent conveyor module each directly with a single fan 50th are connected to provide suction air to the conveyor drums, which is only schematically indicated for reasons of clarity.

Der für die Filteransetzmaschine F vorgesehene (einzige) Ventilator 50 ist so dimensioniert, um alle mit Unterdruck beaufschlagbaren Fördertrommeln oder Arbeitsorgane der Anlage bzw. der Filteransetzmaschine F entsprechend mit Unterdruck zu versorgen.The (single) fan 50 provided for the filter attachment machine F is dimensioned so as to supply all vacuum drums or working members of the installation or the filter attachment machine F with negative pressure.

Bei dem in Fig. 1 gezeigten Ausführungsbeispiel gemäß dem Stand der Technik werden die Fördertrommeln der Trommelanordnung T, bestehend aus den Fördertrommeln 18, 19, 20, 21, 23, 24 mittels des Ventilators 50 mit Unterdruck beaufschlagt, um die queraxial geförderten Tabakstöcke bzw. Artikelgruppen in den Mulden der Fördertrommeln zu halten. Ferner sind die Trommeln 14, 15, 16, 17 der Trommelanordnung M für die Zuführung von Filterstopfen doppelter Länge ebenfalls den Ventilator 50 angeschlossen, der die Fördertrommeln 14, 15, 16, 17 der Trommelanordnung M mit Unterdruck beaufschlagt.At the in Fig. 1 shown embodiment according to the prior art, the conveyor drums of the drum assembly T, consisting of the conveyor drums 18, 19, 20, 21, 23, 24 applied by means of the fan 50 with negative pressure to the queraxial promoted tobacco sticks or article groups in the wells of the conveyor drums to keep.

Darüber hinaus wird auch durch den Ventilator 50 an dem Fördermodul bzw. an der Anordnung der Fördertrommeln 12, 22, 26, 27, 28, 29 jeweils ein entsprechendes Haltevakuum für die zu transportierenden Artikel der Tabak verarbeitenden Industrie bereitstellt.In addition, by the fan 50 to the conveyor module or to the arrangement of the conveyor drums 12, 22, 26, 27, 28, 29 respectively provides a corresponding holding vacuum for the transportable articles of the tobacco processing industry.

Weiterhin versorgt der Ventilator 50 gleichzeitig ebenfalls die Fördertrommeln 30, 31, 33, 34, 35 des nachfolgenden Fördermoduls mit Unterdruck, um die Filterzigaretten auf bzw. in den Mulden der Fördertrommeln zu halten.Furthermore, the fan 50 also simultaneously supplies the conveyor drums 30, 31, 33, 34, 35 of the subsequent conveyor module with negative pressure to keep the filter cigarettes on or in the wells of the conveyor drums.

Ferner kann die Zigarettenstrangmaschine P ebenfalls über einen Ventilator 61 verfügen, der beispielsweise ein Saugband mit Unterdruck versorgt.Furthermore, the cigarette rod maker P can also have a fan 61, which supplies, for example, a suction belt with negative pressure.

Hierbei werden durch den ausschließlich einen Ventilator 50 jeweils die entsprechenden Förderorgane bzw. Arbeitsorgane des Funktionsmoduls oder Fördermoduls mit Unterdruck beaufschlagt.According to the state of the art, the only fan 50 dimensioned in accordance with the vacuum volumes to be provided is operated solely for the corresponding conveyor drums or function modules or conveyor modules, wherein the fan 50 is assigned directly to the conveyor drums (the function modules) , In this case, by the only one fan 50 in each case the corresponding conveying members or working members of the functional module or conveyor module subjected to negative pressure.

Fig. 2 zeigt in einer schematischen Ansicht eine erfindungsgemäße Ausgestaltung einer Filteransetzmaschine F, wobei gleichzeitig mehrere Ventilatoren 51, 52, 53, 54 parallel an einen gemeinsamen Unterdruckversorgungskanal 70 angeschlossen sind, so dass die Fördertrommeln der einzelnen Fördermodule mit Unterdruck aus dem gemeinsamen Unterdruckversorgungskanal 70 beaufschlagt werden. Hierbei sind beispielsweise die Fördertrommeln 18, 19, 20, 23, 24, 21 der Trommelanordnung T parallel an den Unterdruckversorgungskanal 70 angeschlossen. Ebenso sind auch die Fördertrommeln 14, 15, 16, 17 der Trommelanordnung M parallel an den Unterdruckversorgungskanal 70 angeschlossen. Fig. 2 shows a schematic view of an inventive embodiment of a filter attachment machine F, wherein simultaneously a plurality of fans 51, 52, 53, 54 are connected in parallel to a common vacuum supply channel 70, so that the conveyor drums of the individual conveyor modules with negative pressure from the common vacuum supply channel 70 are acted upon. Here, for example, the conveyor drums 18, 19, 20, 23, 24, 21 of the drum assembly T are connected in parallel to the vacuum supply channel 70. Likewise, the conveyor drums 14, 15, 16, 17 of the drum assembly M are connected in parallel to the vacuum supply channel 70.

Auch die Fördertrommeln 12, 22, 26, 28, 29 des Fördermoduls zwischen der Zusammenstelltrommel 21 und der Fördertrommel 30 sind ebenfalls parallel mit dem Unterdruckversorgungskanal 70 verbunden. Auch die Fördertrommeln, 30, 31, 33, 34, 35 des nachfolgenden Förderfunktionsmoduls bzw. Fördermoduls sind jeweils parallel zueinander an den Unterdruckversorgungskanal angeschlossen.Also, the conveyor drums 12, 22, 26, 28, 29 of the conveyor module between the assembly drum 21 and the conveyor drum 30 are also connected in parallel to the vacuum supply passage 70. Also, the conveyor drums, 30, 31, 33, 34, 35 of the subsequent conveyor function module or conveyor module are each connected in parallel to each other to the vacuum supply channel.

In einer schematisch eingezeichneten möglichen Weiterbildung ist auch der Ventilator 61, der gemäß dem Stand der Technik an der Zigarettenstrangmaschine P angeordnet ist (vgl. Fig. 1), parallel zu den Ventilatoren 51, 52, 53, 54 der Filteransetzmaschine F an dem Unterdruckversorgungskanal 70 angeschlossen, so dass auch entsprechende Förderorgane bzw. Arbeitsorgane der Zigarettenstrangmaschine P, die mit Unterdruck beaufschlagt werden, ebenfalls mit Unterdruck aus dem Unterdruckversorgungskanal 70 beaufschlagt werden.In a schematically drawn possible development is also the fan 61, which is arranged according to the prior art on the cigarette rod machine P (see. Fig. 1 ), parallel to the fans 51, 52, 53, 54 of the filter attachment machine F connected to the vacuum supply channel 70, so that also corresponding conveying organs or working organs of the cigarette rod maker P, which are subjected to negative pressure, are also subjected to negative pressure from the vacuum supply channel 70.

Insbesondere haben die Ventilatoren 51, 52, 53, 54 die gleiche Größe, d.h. dass die Druck/Volumenstrom-Kennlinien der Ventilatoren gleich sind. Durch die Parallelschaltung der Ventilatoren 51, 52, 53, 54 über den gemeinsamen Unterdruckversorgungskanal 70 werden plötzlich auftretende Druckschwankungen an der Filteransetzmaschine beispielsweise bei der Entnahme von Filterzigaretten von einer Fördertrommel ausgeglichen, wobei aufgrund der Parallelschaltung der Ventilatoren 51, 52, 53, 54 ein geringerer Druckabfall in dem betreffenden Fördermodul entsteht im Vergleich zu der Ausführungsform, bei der ein Ventilator eines Moduls jeweils mit den entsprechenden Fördertrommeln (vgl. Fig. 1) direkt verbunden ist.In particular, the fans 51, 52, 53, 54 are the same size, that is, the pressure / flow characteristics of the fans are the same. By the parallel connection of the fans 51, 52, 53, 54 via the common vacuum supply channel 70 suddenly occurring pressure fluctuations are compensated at the Filteransetzmaschine for example in the removal of filter cigarettes from a conveyor drum, due to the parallel connection of the fans 51, 52, 53, 54 a lesser Pressure drop in the relevant conveyor module is formed in comparison to the embodiment in which a fan of a module in each case with the corresponding conveyor drums (see. Fig. 1 ) is directly connected.

Insbesondere ist bei der Parallelschaltung der Ventilatoren 51, 52, 53, 54 unter Verwendung des gemeinsamen Unterdruckversorgungskanals 70 die Summe der Druck/Volumenstrom-Kennlinien der einzelnen Ventilatoren 51, 52, 53, 54, in etwa oder annähernd gleich der Summe der einzelnen Ventilatoren für die gesamte Filteransetzmaschine.In particular, in the parallel connection of the fans 51, 52, 53, 54 using the common negative pressure supply channel 70, the sum of the pressure / flow characteristics of the individual fans 51, 52, 53, 54, approximately equal to or approximately equal to the sum of the individual fans for the entire Filteransetzmaschine.

Darüber hinaus ist es im Rahmen der Erfindung denkbar, dass bei einer weiteren Ausgestaltung der Filteransetzmaschine F unter Verwendung weiterer Fördermodule oder Arbeitsorgane, die mit Unterdruck beaufschlagt werden, die Arbeitsorgane des erweiterten Moduls an den Unterdruckversorgungskanal angeschlossen werden, wobei außerdem der Ventilator, der dem Erweiterungsmodul zugeordnet ist, parallel zu den bereits bestehenden und parallel zueinander geschalteten Ventiltoren der entsprechende Module am Unterdruckversorgungskanal 70 saugseitig angeschlossen wird.Moreover, it is conceivable within the scope of the invention that in a further embodiment of the filter attachment F using further conveyor modules or working organs, which are subjected to negative pressure, the working organs of the extended module are connected to the vacuum supply channel, wherein also the fan, the expansion module is assigned, parallel to the already existing and parallel valve connected to the corresponding modules on the vacuum supply channel 70 is connected to the suction side.

Durch die modulare Erweiterbarkeit des Unterdruckversorgungssystems mit den parallel angeschlossenen Ventilatoren und dem gemeinsamen Unterdruckversorgungskanal ist auf einfache Weise ein modulares Unterdruckversorgungssystem einer Maschine der Tabak verarbeitenden Industrie möglich. Bei der Kombination mehrerer Maschinen der Tabak verarbeitenden Industrie zu einer Fertigungsanlage ist ebenfalls eine modulare Bauweise der Einzelmaschinen möglich, wobei für die Kombination der Einzelmaschinen ein gemeinsames Unterdruckversorgungssystem für alle Arbeitsorgane, die mit Unterdruck beaufschlagt werden, denkbar ist.Due to the modular expandability of the vacuum supply system with the parallel connected fans and the common vacuum supply channel is easily a modular vacuum supply system of a machine of the tobacco processing industry possible. In the combination of several machines of the tobacco processing industry to a manufacturing plant is also a modular design of the individual machines possible, for the combination of the individual machines, a common vacuum supply system for all working organs, which are acted upon by negative pressure, is conceivable.

Weiterhin können zusätzlich oder alternativ auf der Saugseite der Ventilatoren 51 , 52, 53, d.h. in den Verbindungsleitungen zwischen dem Unterdruckversorgungskanal 70 und den Ventilatoren 51, 52, 53, in einer Ausgestaltung entsprechende Luftklappen vorgesehen sein.The schematically designated delivery module A has a plurality of workpieces or conveyor drums 81, 82 that can be acted upon by negative pressure, while the delivery module B has conveyor drums 91, 92. Here, the conveyor drums 81, 82 and 91, 92 may also be connected to the vacuum supply channel 70 with the interposition of air dampers and / or Saugluftpufferräumen. Furthermore, additionally or alternatively, on the suction side of the fans 51, 52, 53, i. in the connecting lines between the vacuum supply channel 70 and the fans 51, 52, 53, be provided in one embodiment corresponding louvers.

Vorzugsweise werden Luftklappen in den Verbindungsleitungen zwischen dem Unterdruckversorgungskanal 70 und den Fördertrommeln 81, 82, 91, 92 und Luftklappen in den Verbindungsleitungen zwischen dem Unterdruckversorgungskanal 70 und den Ventilatoren 51, 52, 53 verwendet, wenn die an den Unterdruckversorgungskanal 70 angeschlossenen Ventilatoren 51, 52, 53 ungleich groß sind, d.h. dass beispielsweise die Druck/Volumenstrom-Kennlinien der Ventilatoren 51, 52, 53 die an den gemeinsamen Unterdruckversorgungskanal 70 parallel angeschlossen sind, ungleich oder nicht identisch sind und sich dadurch unterscheiden.Preferably, louvers are used in the communication lines between the negative pressure supply passage 70 and the conveyor drums 81, 82, 91, 92 and louvers in the connection lines between the negative pressure supply passage 70 and the fans 51, 52, 53 when the fans 51, 52 connected to the negative pressure supply passage 70 , 53 are unequal size, ie that, for example, the pressure / flow characteristics of the fans 51, 52, 53 which are connected in parallel to the common negative pressure supply channel 70, are unequal or not identical and thereby differ.

Die weiteren Module C, ... der Maschine verfügen ebenfalls über entsprechende Arbeitsorgane bzw. Förderorgane, die mit dem Unterdruckversorgungskanal 70 verbunden sind. Insbesondere sind die an den Unterdruckversorgungskanal 70 angeschlossenen Ventilatoren 51 52, 53 baugleich ausgebildet, wobei die Ventilatoren insbesondere auch über Druck/Volumenstrom-Kennlinien verfügen, die keine Scheitelpunkte oder Wendepunkte aufweisen.The other modules C,... Of the machine likewise have corresponding working members or conveying members, which are connected to the vacuum supply channel 70.

Durch die Parallelschaltung des Ventilators 51 des Fördermoduls A sowie des Ventilators 52 des Fördermoduls B sowie des Ventilators 43 des Fördermoduls C usw. werden Druckschwankungen an der gesamten Maschine auf einfache Weise ausgeglichen.By the parallel connection of the fan 51 of the conveyor module A and the fan 52 of the conveyor module B and the fan 43 of the conveyor module C and so on, pressure fluctuations on the entire machine are compensated in a simple manner.

Außerdem ist es im Rahmen der Erfindung möglich, dass ein Ventilator, der an den Unterdruckversorgungskanal 70 angeschlossen ist, zusätzlich auch direkt mit einem Förderorgan verbunden ist, um an diesem Förderorgan einen entsprechenden Unterdruck bereitzustellen. Dies ist beispielhaft in Fig. 3 dadurch angedeutet, dass eine Fördertrommel 93 des Fördermoduls B mit dem Ventilator 52 direkt verbunden ist, ohne dass die Fördertrommel 93 an den Unterdruckversorgungskanal 70 angeschlossen ist. Der Ventilator 52 selbst ist außerdem an den Unterdruckversorgungskanal 70 angeschlossen. Insbesondere wird eine Fördertrommel oder ein mit Unterdruck beaufschlagbares Arbeitsorgan direkt mit einem Ventilator verbunden, wenn die Fördertrommel bzw. das Arbeitsorgan einen besonderen Bedarf oder einen Mehrbedarf an Unterdruck erfordert.In addition, it is possible within the scope of the invention that a fan, which is connected to the vacuum supply channel 70, in addition also connected directly to a conveying member to provide a corresponding negative pressure on this conveying member. This is exemplary in Fig. 3 indicated that a conveyor drum 93 of the conveyor module B is connected directly to the fan 52 without the conveyor drum 93 is connected to the vacuum supply channel 70. The fan 52 itself is also connected to the vacuum supply passage 70. In particular, a conveyor drum or an under pressure acted upon working member is connected directly to a fan when the conveyor drum or the working member requires a special need or an additional demand for negative pressure.

Außerdem ist es im Rahmen der Erfindung weiterhin denkbar, dass an einer Anlage oder einer Maschine mehrere, z.B. zwei Unterdruckversorgungssysteme, mit jeweils einem Unterdruckversorgungskanal vorgesehen sind, wobei die Unterdruckversorgungssysteme sowie die Unterdruckversorgungskanäle der Versorgungssysteme voneinander getrennt sind und wobei an die Unterdruckversorgungskanäle jeweils mehrere Ventilatoren parallel saugseitig angeschlossen sind. Hierdurch ist es möglich, eine Maschine oder Anlage der Tabak verarbeitenden Industrie mit verschiedenen Unterdruckniveaus, insbesondere im Produktionsbetrieb, zu betreiben.In addition, it is also conceivable within the scope of the invention that a system or a machine several, eg two vacuum supply systems, each provided with a vacuum supply channel, wherein the vacuum supply systems and the vacuum supply ducts of the supply systems are separated from each other and wherein the vacuum supply channels each more fans in parallel are connected on the suction side. This makes it possible to have a machine or plant of the tobacco industry with different levels of vacuum, especially in production, operate.

Fig. 4 zeigt schematisch ein Diagramm der Kennlinien eines Ventilators und mehrerer Ventilatoren, wobei in dem Diagramm die Totaldruckerhöhung p gegen den Volumenstrom V aufgetragen. Die Kennlinie eines einzelnen Ventilators ist mit V bezeichnet, während die Summenkennlinie von mehreren parallel geschalteten Ventilatoren mit S bezeichnet ist. Fig. 4 schematically shows a diagram of the characteristics of a fan and a plurality of fans, wherein plotted in the diagram, the total pressure increase p against the flow rate V. The characteristic of a single fan is denoted by V, while the sum characteristic of several fans connected in parallel is denoted by S.

Ferner sind im Diagramm mehrere Anlagenkennlinien eingezeichnet. Hierbei sind die Kennlinie für das Fördermodul, an das der eine Ventilator V angeschlossen ist, um an den Förderorganen des Fördermoduls Unterdruck zu erzeugen bzw. bereitzustellen, im Produktionsbetrieb (Kennlinie AMP) und bei Auftreten einer Störung, z.B. einer Entnahme von geförderten Produkten (Kennlinie AME) eingezeichnet. Werden beispielsweise von einer Fördertrommel mehrere Produkte entnommen, so entsteht an dem einen Fördermodul mit dem einen Ventilator beim Übergang von der Produktion (Kennlinie AMP) ein Druckeinbruch (Δp1), da die Förderorgane des Fördermoduls von nur einem Ventilator mit Unterdruck versorgt werden.Furthermore, several system characteristics are shown in the diagram. Here, the characteristic curve for the delivery module to which a fan V is connected in order to produce or provide negative pressure on the conveying elements of the delivery module, in production mode (characteristic curve AMP) and in the event of a malfunction, eg removal of subsidized products (characteristic curve AME). If, for example, several products are removed from a conveyor drum, a pressure drop (Δp 1 ) occurs at one conveyor module with the one fan during the transition from production (characteristic curve AMP) since the conveying elements of the conveyor module are supplied with negative pressure by only one fan.

Ferner sind in Fig. 4 auch die Anlagenkennlinien der Maschine eingezeichnet, wobei die Fördermodule aus dem gemeinsamen Unterdruckversorgungskanal, an dem die Ventilatoren der Fördermodule parallel angeschlossen sind, dargestellt sind. Hierbei ist die Anlagenkennlinie der Maschine bei Produktion bei Parallelschaltung der Ventilatoren mit SMP bezeichnet. Die Anlagenkennlinie der Maschine bei parallel geschalteten Ventilatoren im Entnahmefall oder im Störfall ist mit SME bezeichnet. Die Schnittpunkte der Kennlinien SMP sowie SME mit der Summenkennlinie ergeben die Betriebspunkte L1 sowie L2 der betriebenen gesamten Maschine.Furthermore, in Fig. 4 also the system characteristics of the machine are shown, wherein the conveyor modules from the common vacuum supply channel to which the fans of the conveyor modules are connected in parallel, are shown. In this case, the plant characteristic curve of the machine is designated as SMP when the fans are connected in parallel. The plant characteristic curve of the machine with fans connected in parallel in the case of removal or in case of malfunction is designated SME. The points of intersection of the characteristic curves SMP and SME with the sum characteristic curve yield the operating points L1 and L2 of the entire machine operated.

Beim Übergang vom Produktionsmodus (Betriebspunkt L1) bei Auftreten einer Störung (Betriebspunkt L2), so dass mehr Luft durch die Arbeitsorgane der Maschine von außen angesaugt wird, entsteht ein Druckeinbruch (Δp2), der im Vergleich zum Druckeinbruch (Δp1) an einem einzigen Modul, das über einen direkt angeschlossenen Ventilator mit Unterdruck versorgt wird, kleiner bzw. relativ klein ist. Hierdurch wird der Betrieb der gesamten Anlage aufgrund des geringeren Druckeinbruchs deutlich verbessert.During the transition from the production mode (operating point L1) in the event of a malfunction (operating point L2), so that more air is sucked from the outside by the working organs of the machine, there is a pressure drop (Δp 2 ), compared to the pressure drop (Δp 1 ) at a single module, which is supplied via a directly connected fan with negative pressure, smaller or relatively small. As a result, the operation of the entire system is significantly improved due to the lower pressure drop.

Alle genannten Merkmale, auch die den Zeichnungen allein zu entnehmenden sowie auch einzelne Merkmale, die in Kombination mit anderen Merkmalen offenbart sind, werden allein und in Kombination als erfindungswesentlich angesehen. Erfindungsgemäße Ausführungsformen können durch einzelne Merkmale oder eine Kombination mehrerer Merkmale erfüllt sein.All mentioned features, including the drawings alone to be taken as well as individual features that are disclosed in combination with other features are considered alone and in combination as essential to the invention. Embodiments of the invention may be accomplished by individual features or a combination of several features.
