Definitions
- the invention relates to a device for introducing additives into a strand already provided for the production of a smoking article and having already a round shape, with a guide section through which the strand can be guided in the transport direction, and a feed device acting in the guide section for the downstream feeding of additives into the infeed Lead section strand.
- Such a device is used in particular for the production of cigarette filters, so that in such a case the strand is a filter tow strand.
- the performance of the smoking article can be improved and / or its taste properties can be specifically influenced.
- the introduction of additives, for example in a filter tow for the production of cigarette filters also leads to an improvement in the filter properties, which is often used as an additive activated carbon granules.
- strand is understood primarily as meaning an endless strand, in the context of the present invention it is not excluded that the strand to be processed may also be finite if necessary and, for example, a total length of only a slight multiple of the length of a tobacco or filter rod and possibly only in the order of a rod may have.
- various types of strands can be processed as are suitable for the manufacture of smoking articles.
- tobacco strands can also be treated accordingly with the present device.
- smoking article for the purposes of the present invention smoking articles of all kinds to understand, in particular cigarettes, filter cigarettes, cigarillos and cigars and parts of these fall.
- the feed device used for this purpose consists of an inner permeable tubular wall portion of a guide tube through which the Towstring moves, and a surrounding this tubular wall portion cavity in which the supplied liquid additive is distributed.
- the liquid additive then enters in the radial direction into the interior of the guide tube and thus meets in the radial direction on the circumference of the tow line located in the guide tube.
- additives can be present both in liquid and in pulverized form.
- One way of additive addition is to use in a similar manner as in the EP 0 196 867 A2 to give the additive radially from the outside to the circumference of the Towstranges.
- a delivery tube extends through the wall of a Tow strang receiving guide tube and terminates in a centrally disposed and extending in the transport direction end portion, whereby the additive is fed as a jet substantially punctiform in the middle of the cross-sectional area of the tow strand.
- beats EP 0 128 031 B1 the arrangement of two spaced feed tubes within a guide tube, wherein each of these two spaced supply tubes is oriented with its end portion parallel to the transport direction of the tow strand.
- the additive is injected selectively not only at one point but at two points.
- the bundling of a plurality of feed tubes according to the invention into a common tube bundle leads to a greater distribution of the additive or of the additives over the cross-sectional area of the strand moving through the guide section. This is inventively achieved in that the tube bundle extends in the region of the outlets over a certain cross-sectional area. Thus, even in this embodiment, a selective feed of additive is avoided in the strand.
- the plurality of feed tubes enter the guide section at an angle to the transport direction of the strand and have a section which is curved toward its end in the transport direction.
- the tube bundle can be arranged at the end of the feed tubes approximately centrally within the guide section.
- the guide portion has a channel along which the strand is feasible.
- the guide section may advantageously be designed such that the strand can be guided substantially rectilinearly, at least in the area of the feed device.
- a pneumatic device for generating the strand in the guide section acting transport air may be provided to move the strand in the transport direction by the guide portion.
- a pneumatic device for generating the additive or the additives acting on transport air may be provided in the feed device to feed the additive or additives through the feed device in the guide section.
- a preferred use of the feed device consists in the application of substantially granular additive.
- the device according to the invention is preferably used for introducing additives into a filter tow line intended for the production of a filter for a smoking article and already round-shaped.
- a pneumatically operated transport nozzle can be arranged upstream of the feed device.
- additives are to be introduced or fed into an already round-shaped tow line.
- such a device is used for the production of cigarette filters, so that in such a case the tow strand is a filter tow strand.
- cellulose acetate is used as a material for the manufacture of cigarette filters.
- the device has a guide tube 2, which has an inlet at its end according to the figures right front end and there opens to a funnel 4.
- the guide tube 2 serves to receive a tow line (not shown), which is moved by the guide tube 2 in the transport direction according to arrow A.
- the guide tube 2 has a substantially circular cross-section.
- the inner diameter of the guide tube 2 must be at least slightly larger than the outer diameter of the Towstranges so that the tow strand does not get stuck in the guide tube 2; if necessary, the diameter of the guide tube 2 but also be significantly larger than the diameter of the tow rope therein and be for example in a range of about 30 to 60 mm.
- the guide tube 2 may have a length of about 100 to 300 mm. After all, therefore, the guide tube 2 in the device forms a channel-shaped guide section for the Towstrang.
- the guide tube 2 terminates downstream of a housing 6 designed as a rotary body.
- the housing 6 is provided with an outlet 8, through which the tow strand leaves the illustrated device, in order then to be subjected to further processing steps, which in particular comprise an enclosure Paper, preferably with simultaneous bonding, in a downstream of the illustrated device located (not shown in the figures) format and a division of the Towstranges in discrete filter rods in a downstream (also not shown in the figures) cutting device comprises.
- the housing 6 contains a transport nozzle 18. Since the housing 6 is located downstream of the guide tube 2, located in the illustrated embodiment, the transport nozzle 18 downstream of the guide tube 2. Thus, the tow line, not shown in the figures, passes from the guide tube 2 into the housing 6 and runs there through the transport nozzle 18, before it exits the outlet 8. In addition, it is also conceivable to provide a transport nozzle at the inlet 4 of the guide tube 2 or upstream of the guide tube 2, whereby the tow can be treated in accordance with low prior to feeding the additives.
- the air outlet 10 on the housing 6 also allows the discharge of excess transport air.
- Suction bell 20 connects to the housing 6 downstream, at the downstream end of the outlet 8 is formed.
- the suction bell 20 serves to catch excess additive, which is then sucked off via the air outlet 10.
- a feed device which is formed in the illustrated embodiment of a tube bundle 30, to which a plurality of feed tubes 32 are combined together physically.
- the tube bundle 30 enters at a relatively steep angle through the wall 14 of the guide tube 2, wherein the angle can be up to 90 degrees relative to the transport direction according to arrow A or the center axis of the guide tube 2, not shown.
- the feed pipes 32 have upstream of their end portion 32a on a bent portion 32b, which forms approximately a quarter circle in the illustrated embodiment.
- the bent portion 32 b ensures that the feed tubes 32 are aligned with its end portion 32 a in the transport direction according to arrow A or in the direction of the central axis of the guide tube 2, not shown, such as FIG. 3 recognize.
- FIG. 3 recognize that in the illustrated embodiment, the tube bundle 30 in the region of the end portions 32a of the feed tubes 32 is aligned approximately centrally within the guide tube 2. The latter has the consequence that from the outlets 36 of the end portions 32a of the feed tubes 32, the additives indeed emerge as parallel rays. However, since the tube bundle 30 in the region of the outlets 36 extends over a certain cross-sectional area, such as FIG. 3 can be seen, this configuration also leads to a stronger distribution of the additives over the cross section of the guide tube through the second guided towstranges.
- the additive or additives are distributed over a larger cross-sectional area in the already round towstring, so that a selective feed of additive into the tow strand is avoided.
- the cross-sectional area or the diameter of the tube bundle 30 compared to the inner diameter of the guide tube 2 is significantly smaller, whereby a significant obstruction of the tow strand is avoided during its movement through the guide tube 2; Rather, there is enough room for the Towstrang to move on both sides of the tube bundle 30 over.
- the transport of the additive through the supply pipes 32 takes place by means of compressed air, for which purpose a compressed air source, not shown in the figures, is to be connected to the supply pipes 32.
- a compressed air source not shown in the figures, is to be connected to the supply pipes 32.
- the additive for its transport through the supply pipes 32 is acted upon, accelerated at the outlet 16 of the corresponding feed pipe 32 offered and entrained by the revolving round Towstrang.
- the compressed air After emerging from the feed pipes 32, the compressed air enters the housing 6 and is sucked out of it through the air outlet 10.

Description
Die Erfindung betrifft eine Vorrichtung zum Einbringen von Additiven in einen zur Herstellung eines Rauchartikels vorgesehenen und bereits rundgeformten Strang, mit einem Führungsabschnitt, durch den der Strang in Transportrichtung führbar ist, und einer in den Führungsabschnitt wirkenden Einspeiseeinrichtung zur stromabwärts gerichteten Einspeisung von Additiven in den im Führungsabschnitt befindlichen Strang.The invention relates to a device for introducing additives into a strand already provided for the production of a smoking article and having already a round shape, with a guide section through which the strand can be guided in the transport direction, and a feed device acting in the guide section for the downstream feeding of additives into the infeed Lead section strand.
Eine solche Vorrichtung wird insbesondere für die Herstellung von Zigarettenfiltern verwendet, so dass es sich in einem solchen Fall bei dem Strang um einen Filtertowstrang handelt. Mit dem Einbringen von Additiven lassen sich insbesondere die Leistungsfähigkeit des Rauchartikels verbessern und/oder dessen Geschmackseigenschaften gezielt beeinflussen. Das Einbringen von Additiven beispielsweise in einen Filtertowstrang zur Herstellung von Zigarettenfiltern führt auch zu einer Verbesserung der Filtereigenschaften, wozu häufig als Additiv Aktivkohlegranulat verwendet wird.Such a device is used in particular for the production of cigarette filters, so that in such a case the strand is a filter tow strand. With the introduction of additives, in particular, the performance of the smoking article can be improved and / or its taste properties can be specifically influenced. The introduction of additives, for example in a filter tow for the production of cigarette filters also leads to an improvement in the filter properties, which is often used as an additive activated carbon granules.
Obwohl unter "Strang" in erster Linie ein endloser Strang verstanden wird, ist es im Sinne der vorliegenden Erfindung nicht ausgeschlossen, dass der zu verarbeitende Strang bei Bedarf auch endlich sein und beispielsweise eine Gesamtlänge von nur einem geringfügigen Mehrfachen der Länge eines Tabak- oder Filterstabes und ggf. auch nur in der Größenordnung eines Stabes aufweisen kann. Wie bereits zuvor angedeutet wurde, können verschiedene Arten von Strängen verarbeitet werden, wie sie für die Herstellung von Rauchartikeln in Frage kommen. Auch wenn zur Zeit ein wesentlicher Anwendungsfall bei der Herstellung von Filtern liegt und insoweit es sich dann beim Strang um einen Filtertowstrang handelt, ist es aber auch denkbar, dass mit der vorliegenden Vorrichtung ebenfalls Tabakstränge entsprechend behandelt werden können. Somit sind unter "Rauchartikel" im Sinne der vorliegenden Erfindung Rauchartikel aller Art zu verstehen, unter die insbesondere Zigaretten, Filterzigaretten, Zigarillos und Zigarren sowie Teile von diesen fallen.Although "strand" is understood primarily as meaning an endless strand, in the context of the present invention it is not excluded that the strand to be processed may also be finite if necessary and, for example, a total length of only a slight multiple of the length of a tobacco or filter rod and possibly only in the order of a rod may have. As previously indicated, various types of strands can be processed as are suitable for the manufacture of smoking articles. Although at present an essential application is in the production of filters and insofar as the strand is a filter tow strand, it is also conceivable that tobacco strands can also be treated accordingly with the present device. Thus, "smoking article" for the purposes of the present invention smoking articles of all kinds to understand, in particular cigarettes, filter cigarettes, cigarillos and cigars and parts of these fall.
