Diese Ausbildung ermöglicht eine besonders einfache und sichere Zuführung des Fluids. Ist die Scheibe angetrieben, wird der Strang getaktet mit Fluid beaufschlagt. Steht die Scheibe still, ist die Zuführung des Fluids in Abhängigkeit der Position der Durchgangsbohrungen entweder gestoppt oder der Strang wird kontinuierlich mit Fluid beaufschlagt. An expedient development of the invention is characterized in that the rotary body has at least one disc with a plurality of uniformly distributed over the circumference, radially directed through holes. This design allows a particularly simple and secure supply of the fluid. If the disc is driven, the strand is clocked with fluid acted upon. If the disc is stopped, the supply of fluid is either stopped depending on the position of the through holes or the strand is continuously supplied with fluid.
In einer bevorzugten Ausfuhrungsform der Erfindung umfasst der Drehkörper zwei oder mehr solcher Scheiben, wobei die einzelnen Scheiben in einem axialen Abstand zueinander auf der Hohlwelle gelagert sind. Damit kann in sehr kompakter Weise mehr als ein Strang gleichzeitig parallel und zeitgleich mit einem Fluid versehen werden, was z.B. für eine Zwei- oder Mehrstrangmaschine vorteilhaft ist. In a preferred embodiment of the invention, the rotary body comprises two or more such discs, wherein the individual discs are mounted at an axial distance from each other on the hollow shaft. Thus, more than one strand can be simultaneously and simultaneously provided with a fluid in a very compact manner, e.g. is advantageous for a two-strand or multi-strand machine.
Vorteilhafterweise sind die Scheiben zur Bildung einer Trommel mit einem Advantageously, the discs are for forming a drum with a
hülsenartigen Verbindungselement miteinander verbunden, wobei der sleeve-like connecting element connected to each other, wherein the
Außendurchmesser der Scheiben größer ist als der Außendurchmesser des hülsenartigen Verbindungselementes. Mit dieser Ausführungsform kann die Teileanzahl reduziert werden, da mehrere Stränge gleichzeitig in kompakter und sicherer Weise durch einen einzelnen Rotationskörper mit Fluid beaufschlagt werden können. Outer diameter of the discs is greater than the outer diameter of the sleeve-like connecting element. With this embodiment, the number of parts can be reduced because several strands can be acted upon simultaneously in a compact and safe manner by a single body of revolution with fluid.
Vorzugsweise sind die Innendurchmesser der Durchgangsbohrungen in dem Drehkörper größer als die Innendurchmesser der oder jeder Durchgangsbohrung in der Hohlwelle. Diese Ausbildung optimiert das Strömungsverhalten des Fluids aus dem Aufhahmeraum an den Strang. Die Aufgabe wird auch durch eine Strangmaschine der eingangs genannten Art dadurch gelöst, dass die dem Strangförderer zugeordnete Vorrichtung zum Zuführen von Fluiden nach einem der Ansprüche 1 bis 5 ausgebildet ist. Die sich daraus ergebenden Vorteile wurden bereits im Zusammenhang mit der Vorrichtung selbst beschrieben, weshalb zur Vermeidung von Wiederholungen auf die entsprechenden Passagen verwiesen wird. Preferably, the inner diameters of the through-holes in the rotary body are larger than the inner diameters of the or each through-hole in the hollow shaft. This design optimizes the flow behavior of the fluid from the receiving space to the strand. The object is also achieved by a stranding machine of the type mentioned in that the strand conveyor associated device for supplying fluids according to one of claims 1 to 5 is formed. The resulting advantages have already been described in connection with the device itself, so reference is made to avoid repetition on the corresponding passages.
Eine bevorzugte Weiterbildung der Strangmaschine ist dadurch gekennzeichnet, dass die Vorrichtung zum Zuführen von Fluiden in Transportrichtung T des oder jedes Stranges hinter dem Trimmmittel angeordnet ist. Damit wird sichergestellt, dass die Zuführung des Fluids erst dann an den Strang erfolgt, wenn dieser seine endgültige Masse hat. Anders ausgedrückt wird vermieden, dass bereits besprühte Teile des Strangs durch das Trimmmittel abgeschnitten werden, was zu Verlusten beim Fluid führen würde. Außerdem würde bereits besprühter, abgetrennter Tabak in den A preferred development of the stranding machine is characterized in that the device for supplying fluids in the transport direction T of the or each strand is arranged behind the trim means. This ensures that the supply of the fluid only takes place on the strand when it has its final mass. In other words, it is avoided that already sprayed parts of the strand are cut off by the trimming agent, which would lead to losses in the fluid. In addition, already sprayed, separated tobacco in the
Tabakkreislauf zurück geführt werden und somit würden Undefinierte, besprühte Tabakzusammensetzungen entstehen. Tobacco cycle are led back and thus undefined, sprayed tobacco compositions arise.
Vorteilhafterweise ist die Vorrichtung zum Zuführen von Fluid unterhalb der Advantageously, the device for supplying fluid below the
Saugbandeinheit angeordnet. Bei dieser Ausführungsform ist die Vorrichtung komplett auf der Unterseite angeordnet, was eine platzsparende Positionierung darstellt. Ein weiterer Vorteil besteht darin, dass das Fluid dadurch direkt und nahezu verlustfrei auf den Strang gebracht werden kann, da der Spritz- oder Sprühweg des Fluids frei von störenden Komponenten und dergleichen ist. Saugbandeinheit arranged. In this embodiment, the device is arranged completely on the underside, which represents a space-saving positioning. Another advantage is that the fluid can be brought directly and almost lossless on the strand, since the spray or Sprühweg of the fluid is free of interfering components and the like.
Eine weitere besonders zweckmäßige Ausfuhrungsform der Erfindung zeichnet sich dadurch aus, dass die Vorrichtung zum Zuführen von Fluiden integraler Bestandteil der Saugbandeinheit ist, derart, dass die Vorrichtung zum Zuführen von Fluiden eine Umlenk- oder Bandlaufrolle der Saugbandeinheit bildet. Dies ermöglicht eine besonders kompakte und effiziente Einbindung der Vorrichtung zum Zuführen von Fluiden in eine Strangmaschine, wobei des Weiteren auch die Teileanzahl reduziert wird. Die üblicherweise endlos umlaufenden Saugbänder der Saugbandeinheiten werden im Übergabebereich der Stränge von den Saugbändern an die Formatbänder mittels Umlenkrollen oder Bandlaufrollen umgelenkt. Anstelle einer üblichen Umlenk- oder Bandlaufrolle kann die weiter oben beschriebene Vorrichtung zum Zuführen von Fluiden eingesetzt sein, so dass die Vorrichtung zum Zuführen von Fluiden mit einer Doppelfunktion versehen ist. Das Zuführen des Fluids erfolgt dann durch das ohnehin perforiert ausgebildete Saugband. Eine weitere zweckmäßige Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass die Vorrichtung zum Zuführen von Fluiden integraler Bestandteil des Another particularly expedient embodiment of the invention is characterized in that the device for supplying fluids is an integral part of the suction belt unit, such that the device for supplying fluids forms a deflection or belt roller of the suction belt unit. This allows a particularly compact and efficient integration of the device for supplying fluids into a stranding machine, wherein furthermore also the number of parts is reduced. The usually endless circulating suction belts of the suction belt units are deflected in the transfer region of the strands of the suction belts to the format belts by means of deflection rollers or belt rollers. Instead of a conventional deflection or belt roller, the device described above for supplying Be used fluids, so that the device for supplying fluids is provided with a dual function. The feeding of the fluid then takes place through the already perforated trained suction belt. A further expedient development of the invention is characterized in that the device for supplying fluids is an integral part of the
Trimmmittels ist. Die Vorteile der sich daraus ergebenden Doppelfunktion wurden bereits im Zusammenhang mit einer anderen Ausführungsform beschrieben. Der Vorteil dieser Weiterbildung liegt wie bei der Anordnung nach dem Trimmen darin, dass das Fluid direkt und unmittelbar in den Strang gebracht werden kann, was die Fluidverluste bei der Zuführung minimiert. Trimming agent is. The advantages of the resulting dual function have already been described in connection with another embodiment. The advantage of this development is, as in the arrangement after trimming, that the fluid can be brought directly and directly into the strand, which minimizes the fluid losses during the feeding.
Die Aufgabe wird des Weiteren durch ein Verfahren mit den eingangs genannten Schritten dadurch gelöst, dass das Fluid, das innerhalb eines Aufnahmeraums einer Hohlwelle der Vorrichtung zum Zuführen unter Druck bevorratet wird, zum Besprühen des oder jedes Strangs durch Rotieren eines auf der Hohlwelle gelagerten Drehkörpers der Vorrichtung zum Zuführen entspannt wird, indem Durchgangsbohrungen des Drehkörpers mit Durchgangsbohrungen der Hohlwelle in Überdeckung gebracht werden. Die Vorteile, die das erfindungsgemäße Verfahren gegenüber dem Stand der Technik bildet, wurden bereits im Zusammenhang mit der Vorrichtung zum Zuführen sowie der Strangmaschine ausgeführt. The object is further achieved by a method with the steps mentioned above in that the fluid, which is stored within a receiving space of a hollow shaft of the device for supplying pressurized, for spraying the or each strand by rotating a mounted on the hollow shaft body Feeding device is relaxed by bringing through holes of the rotary body with through holes of the hollow shaft in register. The advantages of the method according to the invention over the prior art have already been implemented in connection with the feeding device and the stranding machine.

Der Strangförderer 13, 14 weist (in Abhängigkeit der Anzahl der zu produzierenden Stränge) eine described processing industry, namely a 4-strand cigarette rod machine, with details of the description of essential processing elements is omitted. The material to be processed into a strand 12 (tobacco fleece, filter fleece or the like) is fed to a strand conveyor 13, 14. The strand conveyor 13, 14 has (depending on the number of strands to be produced) one
Saugbandeinheit 15 oder mehrere Saugbandeinheiten 15, 16, 17, 18 mit entsprechenden Saugbändern auf. Die perforiert ausgebildeten Saugbänder sind umlaufende und um Umlenk- oder Bandlaufrollen 19 bzw. Antriebsrollen geführte Bandförderer, so dass die Stränge 12 mittels Ansaugen hängend transportiert werden.

Saugbandeinheit 15 bis 18 ist ein übliches Trimmmittel 20, 21, 22, 23 zum Trennen überschüssiger Anteile von den Strängen 12 angeordnet. In Transportrichtung T hinter den Trimmmitteln 20 bis 23 und kurz vor dem Auslaufen bzw. Umlenken der Saugbandeinheit 15 to 18 is a conventional trim means 20, 21, 22, 23 arranged for separating excess portions of the strands 12. In the transport direction T behind the trim means 20 to 23 and shortly before the leakage or redirecting the
Saugbänder 15 bis 18 ist korrespondierend zu jeder Saugbandeinheit 15 bis 18 ein (nicht explizit dargestelltes) Formatband angeordnet, das zur Weiterführung und Formung des jeweiligen Strangs 12 dient. Des Weiteren umfasst die Strangmaschine 11 optional die erfindungsgemäße Vorrichtung 10 zum Zufuhren von Fluiden in den Strang 12. Suction belts 15 to 18 is arranged corresponding to each Saugbandeinheit 15 to 18 (not explicitly shown) format tape, which serves for continuation and shaping of the respective strand 12. Furthermore, the stranding machine 11 optionally comprises the device 10 according to the invention for supplying fluids into the strand 12.
Die Vorrichtung 10, die zum Zuführen von Fluiden in einen Strang 12 ausgebildet und eingerichtet ist, umfasst eine mit einem Druckelement 24 versehene Einspritzeinheit 25. Erfindungsgemäß weist die Einspritzeinheit 25 eine stehende Hohlwelle 26 sowie einen rotierend antreibbaren und auf der Hohlwelle 26 dichtend gelagerten Drehkörper 27 auf. Die Hohlwelle 26 weist einen an das Druckelement 24 angeschlossenen Aufnahmeraum 28 für das Fluid auf. Damit das Fluid aus dem Aufnahmeraum 28 nach außen strömen kann, ist mindestens eine vom Aufnahmeraum 28 nach außen gerichtete The device 10, which is designed and arranged for supplying fluids into a strand 12, comprises an injection unit 25 provided with a pressure element 24.

The hollow shaft 26 has a connected to the pressure element 24 receiving space 28 for the fluid. So that the fluid can flow out of the receiving space 28 to the outside, at least one of the receiving space 28 is directed outward
Durchgangsbohrung 29 vorgesehen. Der Drehkörper 27 weist ebenfalls mindestens eine Durchgangsbohrung 30 auf. Die Durchgangsbohrungen 29, 30 sind im Wesentlichen radial ausgerichtet. Durchgangsbohrung bedeutet in diesem Zusammenhang lediglich, dass eine durchgehende Verbindung zwischen dem innen liegenden Aufnahmeraum 28 und der äußeren Umgebung für die Hohlwelle 26 bzw. zwischen einer inneren Through hole 29 is provided. The rotary body 27 also has at least one through-bore 30. The through holes 29, 30 are aligned substantially radially. Through hole in this context only means that a continuous connection between the inner receiving space 28 and the outer environment for the hollow shaft 26 and between an inner
Lagerbohrung 31 und der äußeren Umgebung für den Drehkörper 27 besteht, ohne das es zunächst auf die Ausformung der Durchgangsbohrungen 29, 30 ankommt. DieBearing bore 31 and the outer environment for the rotary body 27 is, without it first on the formation of the through holes 29, 30 arrives. The
Hohlwelle 26 ist ein ortsfester und stehender Körper. Das bedeutet, dass die Position der oder jeder Durchgangsbohrung 29 konstant ist. Der Drehkörper 27 ist rotierend antreibbar. Durch das Drehen des Drehkörpers 27 um die Hohlwelle 26 herum ist die oder jede Durchgangsbohrung 30 des Drehkörpers 27 mindestens temporär in Hollow shaft 26 is a stationary and upright body. This means that the position of the or each through-hole 29 is constant. The rotary body 27 is rotationally driven.

Durchgangsbohrungen 30 auf. Selbstverständlich kann die Verteilung über den Umfang auch wahllos sein. Eine Vorrichtung 10 mit einer einzelnen Scheibe 32 ist für eine Einstrangmaschine besonders geeignet. Für eine Zweistrangmaschine umfasst der Drehkörper 27 zwei solcher Scheiben 32 entsprechend der Figur 4, wobei die einzelnen Scheiben 32 in einem axialen Abstand auf der Hohlwelle 26 gelagert sind. Die Scheiben 32 sind in einem Abstand, der dem Abstand der beiden Stränge 12 entspricht, auf der Hohlwelle 26 angeordnet, wobei die Scheiben 32 wahlweise mit unterschiedlicher oder gleicher Geschwindigkeit antreibbar sind. Die Anzahl der Scheiben 32 hängt von der Anzahl der parallel und/oder zeitgleich mit Fluiden zu beaufschlagenden Strängen 12 ab. Die einzelnen Scheiben 32 können unabhängig voneinander auf der Hohlwelle 26 gelagert sein. Bevorzugt sind die Scheiben 32 jedoch miteinander verbunden bzw. zumindest synchronisiert. Besonders bevorzugt ist eine Ausfuhrungsform, bei der die Scheiben 32 zur Bildung einer Trommel 33 mit einem hülsenartigen Through holes 30 on. Of course, the distribution over the scope can also be random. A device 10 with a single disc 32 is particularly suitable for a single-strand machine. For a two-strand machine, the rotary body 27 comprises two such disks 32 according to FIG. 4, the individual disks 32 being mounted on the hollow shaft 26 at an axial distance. The disks 32 are arranged on the hollow shaft 26 at a distance which corresponds to the spacing of the two strands 12, wherein the disks 32 can be driven optionally at different or the same speed. The number of disks 32 depends on the number of strands 12 to be acted upon in parallel and / or simultaneously with fluids. The individual discs 32 may be mounted independently of each other on the hollow shaft 26. However, the disks 32 are preferably connected to each other or at least synchronized. Particularly preferred is an embodiment in which the discs 32 for forming a drum 33 with a sleeve-like
Verbindungselement 34 miteinander verbunden sind. Die Trommel 33 kann über die gesamte Länge in axialer Richtung einen gleichbleibenden Durchmesser aufweisen. Vorzugsweise ist der Außendurchmesser der Scheiben 32 aber größer als der Connecting element 34 are connected together.

Jede der Durchgangsbohrungen 29, 30 kann durchgängig mit einem einheitlichen Durchmesser versehen oder gestuft ausgebildet sein. Es besteht weiterhin die The design and arrangement of the through holes 29, 30 may in principle vary. For example, the inner diameters of the through holes 29, 30 may be identical. In preferred embodiments, the inner diameters of the through-holes 30 in the rotary body 27 or more precisely in the discs 32 are larger than the inner diameters of the through-holes 29 in the hollow shaft 26.

Durchgangsbohrung sich verändernden Durchmesser bzw. Querschnitt aufweisen, beispielsweise indem sich die Innendurchmesser der Durchgangsbohrungen 29, 30 von innen nach außen verjüngen, um einen Düseneffekt zu erzielen. Die Through hole have varying diameter or cross-section, for example, by the inner diameter of the through holes 29, 30 of taper inwards to create a jet effect. The
Durchgangsbohrungen 30 im Drehkörper 27 können bezüglich ihrer Ausrichtung auch versetzt zur Mittelachse M der Hohlwelle 26 bzw. zur Drehachse D des Drehkörpers 27 angeordnet sein. Anders ausgedrückt können die Durchgangsbohrungen 30 in einem (spitzen) Winkel zur radialen Ausrichtung angeordnet sein. Through holes 30 in the rotary body 27 may be arranged with respect to their orientation also offset from the central axis M of the hollow shaft 26 and the axis of rotation D of the rotary body 27. In other words, the through-holes 30 may be disposed at an (acute) angle for radial alignment.

In the rotary body 27 and more precisely in the trim plate 35, at least one through-hole 38 is formed.
Vorzugsweise weist die Trimmscheibe 35 mehrere Durchgangsbohrungen 38 auf, wobei die Anzahl der Durchgangsbohrungen 38 der Anzahl der Trimmtaschen 36 entspricht. Die Durchgangsbohrungen 38 sind im Wesentlichen radial gerichtet. Im Wesentlichen radial bedeutet, dass sich die Durchgangsbohrungen 38 von einer Lagerbohrung 39 radial nach außen erstrecken jeweils in eine Trimmtasche 36 münden. Dabei können die Durchgangsbohrungen 38 seitlich in die Trimmtaschen 36 (siehe z.B. Figur 5), also in radialer Richtung, oder von unten in die Trimmtaschen 36 (siehe z.B.

Sobald der Strang 12 die Vorrichtung 10 erreicht hat, wird der Strang 12 je nach Bedarf gar nicht, getaktet oder kontinuierlich mit dem Fluid besprüht oder bespritzt. Das Besprühen bzw. The material to be processed into a strand 12 is fed in a known manner to the strand conveyor 13, 14 and more precisely to the suction belts of the suction belt units 15 to 18. The hanging from the suction belts strand 12 is transported in the transport direction T, so that the strand 12 passes past a plurality of processing elements in the region of the device 10 for supplying fluids. As soon as the strand 12 has reached the device 10, the strand 12 is not at all, as required, clocked or sprayed or sprayed continuously with the fluid. The spraying or
Bespritzen erfolgt, indem das Fluid, das innerhalb des Aufnahmeraums 28 der Splashing takes place by the fluid, which within the receiving space 28 of the
Hohlwelle 26 der Vorrichtung 10 unter Druck bevorratet wird, durch Rotieren des Drehkörpers 27 um die Hohlwelle 26 herum entspannt wird. Die Entspannung wird dadurch erreicht, dass die Durchgangsbohrungen 30 des Drehkörpers 27 mit den Durchgangsbohrungen 29 der Hohlwelle 26 in Überdeckung gebracht werden. Anders ausgedrückt wird durch eine mindestens temporäre Überdeckung der Hollow shaft 26 of the device 10 is stored under pressure, is relaxed by rotating the rotary body 27 around the hollow shaft 26 around. The relaxation is achieved in that the through holes 30 of the rotary body 27 are brought into coincidence with the through holes 29 of the hollow shaft 26. In other words, by an at least temporary coverage of the

Aufnahmeraum 28 und der Umgebung geschaffen. Der Druck innerhalb des Aufnahmeraums 28 ist optional z.B. über ein Ventil steuerbar und insbesondere abschaltbar. In einigen Ausfuhrungsformen wird das Fluid direkt auf den Strang 12 gesprüht. Bei anderen Ausführungsformen wird das Fluid indirekt, z.B. durch das Saugband der Saugbandeinheiten 15 bis 18 hindurch, auf den Strang 12 gesprüht. Bei noch anderen Ausführungsformen wird das Fluid durch das Trimmmittel 20 bis 23 selbst auf den Strang 12 gesprüht. Das Sprühen kann getaktet oder kontinuierlich erfolgen. Der Zeitpunkt des Besprühens kann ebenfalls variieren. Bei einzelnen Ausführungsformen erfolgt das Zufuhren des Fluids nach einem Recording room 28 and the environment created. The pressure within the receiving space 28 is optionally controllable eg via a valve and in particular switched off. In some embodiments, the fluid is sprayed directly onto the strand 12. In other embodiments, the fluid is sprayed onto the strand 12 indirectly, eg, through the suction belt of the suction belt assemblies 15-18. In yet other embodiments, the fluid is sprayed onto the strand 12 by the trim means 20 to 23 itself. The spraying can be timed or continuous. The time of spraying may also vary. In some embodiments, the supply of the fluid takes place after a
Trimmvorgang, der durch die Trimmmittel 20 bis 23 der Strangmaschine 1 1 ausgeführt wird. In weiteren Ausführungen wird das Fluid durch die Trimmmittel 20 bis 23 selbst auf den Strang 12 aufgetragen, indem das Fluid durch die Trimmscheibe 35, die Bestandteil des Drehkörpers 27 ist, strömt. Das bedeutet, dass während des Trimmens bzw. Trennens von überschüssigen Anteilen des Strangs 12 dieser positions- und zeitgleich an der Trimm- bzw. Trennposition mit Fluid beaufschlagt wird. Bei der letztgenannten Ausführung kann das Fluid aus dem Aufnahmeraum 28 der Hohlwelle 26 durch deren Durchgangsbohrung 29 und die Durchgangsbohrung 38 der Trimming process, which is performed by the trim means 20 to 23 of the stranding machine 1 1. In further embodiments, the fluid is applied by the trim means 20 to 23 even on the strand 12 by the fluid through the trim plate 35, which is part of the rotary body 27, flows. This means that during the trimming or separation of excess portions of the strand 12, this position and time at the trim or separation position is acted upon with fluid. In the latter embodiment, the fluid from the receiving space 28 of the hollow shaft 26 through the through hole 29 and the through hole 38 of the
Trimmscheibe 35 in die Trimmtaschen 36 strömen. Das Einströmen des Fluids in die Trimmtasche 36 kann einerseits seitlich, also im Wesentlichen radial, und andererseits von unten, also im Wesentlichen axial erfolgen. Bei der im Wesentlichen axialen Zuführung ist die Durchgangsbohrung 38 aus der radialen Ausrichtung umgelenkt. Trim disk 35 flow into the trimming pockets 36. The inflow of the fluid into the trimming pocket 36 can take place on the one hand laterally, that is to say essentially radially, and on the other hand from below, that is, essentially axially. In the substantially axial feed, the through-hole 38 is deflected from the radial orientation.
