Description

Die vorliegende Erfindung betrifft eine Vorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1.
Im Rahmen der Herstellung von Zigaretten ist es bekannt, den Zigaretten Geschmacks- und/oder Aromastoffe zuzusetzen, wie z.B aus dem Dokument DE 10 2009 058 589 A1 . Beispielsweise ist bekannt, bahnförmiges Material für eine (Innen-)Umhüllung einer Zigarettenpackung bereits vor der Herstellung der Zigarettenpackungen mit einer Mentholschicht zu versehen. Die Mentholschicht wird dabei auf diejenige Seite des bahnförmigen Umhüllungsmaterials aufgebracht, die bei der späteren fertigen Zigarettenpackung nach innen zeigt und die Zigarettengruppe dabei zumindest bereichsweise überdeckt. Das Menthol kann anschließend von der Umhüllung in die Zigaretten strömen. Die Materialbahnen werden dabei von dem Hersteller solcher Bahnen auf Bobinen gewickelt und anschließend an die Zigarettenproduzenten geliefert. Letztere verwenden diese Bobinen im Rahmen der Fertigung der Zigarettenpackungen und stellen diese als Ausgangsmaterial den Verpackungsmaschinen zu.
The present invention relates to a device having the features of the preamble of claim 1.
In the context of the production of cigarettes, it is known to add flavoring and / or flavoring substances to the cigarettes, for example from the document DE 10 2009 058 589 A1 , For example, it is known to provide web-like material for an (inner) wrapping of a cigarette packet with a menthol layer even before the cigarette packets are produced. The menthol layer is applied to that side of the web-shaped wrapping material, which points inwards during the later finished cigarette packet and covers the cigarette group at least partially. The menthol can then flow from the wrapper into the cigarettes. The webs are wound by the manufacturer of such webs on bobbins and then delivered to the cigarette producers. The latter use these reels as part of the production of the cigarette packs and supply them as starting material to the packaging machines.

Nachteilig hierbei ist, dass durch das Aufwickeln der mit der Mentholschicht versehenen Materialbahnen auf die Bobinen das Menthol häufig ungewollt von der beschichteten Außenseite einer weiter innen angeordneten Wickellage auf die Innenseite der nächstfolgenden Wickellage übertragen wird (oder ggf. umgekehrt). Mit anderen Worten werden hierdurch die eigentlich unbeschichteten Seiten der Materialbahn mit Menthol kontaminiert. Im Produktionsprozess der Zigarettenpackungen müssen die Mentholkristalle dann von der "falschen" Materialbahnseite mühsam wieder entfernt werden, da ansonsten verschiedenste Organe der jeweiligen Verpackungsmaschine durch die Mentholkristalle ungewollt verunreinigt werden.The disadvantage here is that the menthol is often unintentionally transferred from the coated outer side of a further inwardly disposed winding layer on the inside of the next following winding layer by winding the provided with the menthol layer material webs on the reels (or possibly vice versa). In other words, the actually uncoated sides of the material web are thereby contaminated with menthol. In the production process of the cigarette packs, the menthol crystals then have to be painstakingly removed again from the "wrong" material web side be otherwise contaminated organs of the respective packaging machine by the Mentholkristalle unintentionally.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen vorzuschlagen, mit der solche Verunreinigungen der Verpackungsmaschine vermieden oder reduziert werden können.The invention has for its object to propose measures with which such contamination of the packaging machine can be avoided or reduced.

Diese Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Anspruchs 1.This object is achieved by a device having the features of claim 1.

Es ist ein Verfahren vorgesehen zum Herstellen einer Verpackung für eine Gruppe von rauchbaren Artikeln, insbesondere Zigaretten, mit einer Umhüllung aus dünnem Verpackungsmaterial, bei dem eine Materialbahn des Verpackungsmaterials in einzelne Zuschnitte getrennt wird, und bei dem die zu umhüllenden Artikelgruppen jeweils mit den einzelnen Zuschnitten umhüllt werden. Auf die Verpackungsmaterialbahn werden Geschmacks- und/oder Aromastoffportionen für die rauchbaren Artikel aufgebracht, die nach dem Aufbringen durch ein Bearbeitungsmittel mindestens bereichsweise in ihrer Höhe reduziert werden, bevorzugt, indem sie durch das Bearbeitungsmittel flachgestrichen und/oder flachgedrückt werden.A method is provided for producing a package for a group of smokable articles, in particular cigarettes, with a wrapping of thin packaging material, in which a material web of the packaging material is separated into individual blanks, and in which the article groups to be wrapped in each case with the individual blanks be wrapped. Flavor and / or aroma portions for the smokable articles are applied to the packaging material web, which are at least partially reduced in height after application by a processing means, preferably by being flattened and / or flattened by the processing means.

Demnach ist vorgesehen, die Geschmacks- und/oder Aromastoffportionen unmittelbar im Verpackungsprozess auf die Verpackungsmaterialbahn aufzubringen und die einzelnen aufgebrachten Portionen anschließend durch ein geeignetes Bearbeitungsmittel in ihrer Höhe zu reduzieren bzw. flachzustreichen und/oder flachzudrücken, um hierdurch Verschmutzungen der nachfolgenden Organe zu verhindern. Ohne dieses Flachstreichen und/oder Flachdrücken derselben würde ansonsten die Gefahr bestehen, dass sämtliche nachfolgenden Aggregate mit dem Geschmacks- und/oder Aromastoff belastet werden.Accordingly, it is provided to apply the flavor and / or aroma portions directly in the packaging process on the packaging material web and then reduce the individual applied portions by a suitable processing means in height or flatten and / or flatten, thereby preventing contamination of the subsequent organs. Without this flattening and / or flattening of the same would otherwise risk that all subsequent units are charged with the flavor and / or flavor.

Dies gilt insbesondere für ein Trennorgan, mit dem die einzelnen Zuschnitte von der fortlaufenden Materialbahn abgetrennt werden. Bei dem Trennorgan handelt es sich häufig um eine Messerwalze, deren Messer ansonsten kontaminiert werden würden.This applies in particular to a separating element with which the individual blanks are separated from the continuous material web. The separating device is often a knife roller whose blades would otherwise be contaminated.

Bevorzugt ist das Bearbeitungsmittel daher stromauf des Trennorgan angeordnet, insbesondere zwischen einem Auftragsorgan mit einem oder mehreren Auftragsventilen, mit dem die Portionen auf die Materialbahn aufgebracht werden, und dem Trennorgan.Preferably, the processing means is therefore arranged upstream of the separating member, in particular between an applicator member with one or more application valves, with which the portions are applied to the material web, and the separating member.

Zweckmäßigerweise werden die Portionen auf diejenige Seite der Verpackungsmaterialbahn aufgebracht, die nach dem Umhüllungsvorgang nach innen in Richtung der Artikelgruppe zeigt. Die Zigarettengruppe kann dabei teilweise oder vollständig von der Umhüllung umhüllt sein. Die Umhüllung ist vorzugsweise eine Innenumhüllung aus Stanniol, Papier oder Folie einer Zigarettenpackung, die zusätzlich noch eine entsprechende Außenumhüllung bzw. -verpackung aufweist, in der die Innenumhüllung angeordnet ist.The portions are expediently applied to that side of the packaging material web which, after the wrapping process, points inwards in the direction of the article group. The cigarette group can be partial or completely enveloped by the cladding. The wrapper is preferably an inner wrapper made of tinfoil, paper or foil of a cigarette packet which additionally has a corresponding outer wrapper or packaging in which the inner wrapper is arranged.

Das Bearbeitungsmittel ist vorzugsweise eine stromab des Auftragsorgans angeordnete, beheizte bzw. beheizbare Walze, insbesondere eine Umlenkwalze, entlang der die Materialbahn nach dem Auftragen der Portionen zum Flachdrücken derselben geführt wird. Zu diesem Zweck wird die Materialbahn bevorzugt unter leichter Spannung entlang eines Teilbereichs des Umfangs der Walze geführt und dabei mindestens leicht umgelenkt.The processing means is preferably a heated or heatable roller arranged downstream of the application member, in particular a deflection roller, along which the material web is guided after the application of the portions for flattening the same. For this purpose, the material web is preferably guided under slight tension along a portion of the circumference of the roller and thereby deflected at least slightly.

Alternativ kann das Bearbeitungsmittel auch mindestens eine Leiste sein oder eine solche Leiste umfassen, mit der die Portionen flachgestrichen, insbesondere glattgestrichen werden. Die Leiste wird zweckmäßiger Weise parallel zu der Materialbahn geführt, natürlich benachbart zu der Seite, auf der die Portionen aufgebracht werden. Vorzugsweise wird die Materialbahn ähnlich wie bei der obigen Lösung mit Umlenkwalze unter leichter Spannung entlang der Leiste geführt und dabei ebenfalls mindestens leicht umgelenkt.Alternatively, the processing means may also be at least one bar or comprise such a bar with which the portions are flat-stripped, in particular smoothed. The strip is conveniently guided parallel to the material web, of course adjacent to the side on which the portions are applied. Preferably, the web is similar to the above solution with deflecting guided under slight tension along the bar and thereby also at least slightly deflected.

Vorzugsweise bildet die Leiste dabei einen Teil einer Düse des Ventils des Auftragsorgans. Bevorzugt wird eine an die Düsenöffnung angrenzende, stromab der Düsenöffnung angeordnete Düseninnenfläche durch die Leiste bzw. durch eine Seite der Leiste gebildet.Preferably, the strip forms part of a nozzle of the valve of the applicator member. Preferably, a nozzle inner surface adjoining the nozzle opening and arranged downstream of the nozzle opening is formed by the strip or by one side of the strip.

Insofern das Auftragsorgan mehrere, quer zur Materialbahnförderrichtung nebeneinander angeordnete Ventile umfasst, kann die entsprechende Düseninnenfläche jeder Düse jedes Ventils in dieser Weise durch eine allen Ventilen gemeinsam zugeordnete Leiste gebildet werden.Insofar as the applicator member comprises a plurality of valves arranged juxtaposed transversely to the material web conveying direction, the corresponding nozzle inner surface of each nozzle of each valve can be formed in this way by a bar associated with all the valves.

Gemäß einer weiteren wichtigen Besonderheit der Erfindung erfolgt das Auftragen der Portionen auf die Materialbahn derart, dass die Gesamtmenge der pro Zuschnitt auf die Materialbahn aufgebrachten Einzelportionen unabhängig von der Maschinengeschwindigkeit der Vorrichtung und/oder der Materialbahngeschwindigkeit konstant bleibt. Dabei kann vorgesehen sein, dass bei identischer Gesamtportionsmenge pro Zuschnitt die Anzahl von Einzelportionen, die auf einen Zuschnitt aufgebracht werden, nach Maßgabe der Maschinengeschwindigkeit und/oder der Materialbahngeschwindigkeit erfolgt. In weiterer Ausbildung dieser Ausführungsform ist vorgesehen, dass bei identischer Gesamtportionsmenge pro Zuschnitt bei einer ersten, niedrigeren Maschinen- und/oder Materialbahngeschwindigkeit pro Zuschnitt mehr Einzelportionen auf die Materialbahn aufgebracht werden als bei einer zweiten, höheren Geschwindigkeit.According to another important feature of the invention, the portions are applied to the material web in such a way that the total amount of individual portions applied to the material web per blank remains constant, independently of the machine speed of the apparatus and / or the web speed. It can be provided that with an identical total portion quantity per blank, the number of individual portions, which are applied to a blank, in accordance with the speed of the machine and / or the web speed he follows. In a further embodiment of this embodiment, it is provided that with identical total serving quantity per blank at a first, lower machine and / or material web speed per blank more individual portions are applied to the material web than at a second, higher speed.

Diese Maßnahmen haben insbesondere den Zweck zu verhindern, dass sich zu viel Geschmacks- und/oder Aromastoffe bei beispielsweise (zu) langsamer Maschinengeschwindigkeit auf ein und derselben Stelle anhäufen.In particular, these measures have the purpose of preventing too much flavoring and / or flavoring substances from accumulating at one and the same place, for example at (too) slow machine speed.

Weitere Besonderheiten der Erfindung ergeben sich aus den beigefügten Unteransprüchen, aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie aus den beigefügten Zeichnungen.Other features of the invention will become apparent from the appended subclaims, from the following description of preferred embodiments and from the accompanying drawings.

Die Zeichnungen befassen sich mit der Fertigung von Zigarettenpackungen, speziell mit der Fertigung einer Innenumhüllung aus Stanniol, Papier oder Folie für die Zigarettenpackungen. Vornehmlich Hinge-Lid-Packungen oder Weichbecherpackungen weisen derartige, von einer Außenumhüllung umfasste Innenumhüllungen auf. Solche Zigarettenpackungen werden mit Verpackungsmaschinen hergestellt, von denen nachfolgend nur ein Teil dargestellt ist, nämlich der Bereich, in dem die einzelnen Zigarettengruppen in die Innnenumhüllungen eingehüllt werden.The drawings are concerned with the manufacture of cigarette packs, especially with the manufacture of an inner wrapping of tinfoil, paper or foil for the cigarette packs. In particular, hinge-lid packs or soft-cup packs have such inner sheaths covered by an outer sheath. Such cigarette packs are produced with packaging machines, of which only one part is shown below, namely the area in which the individual groups of cigarettes are enveloped in the inner sheaths.

Die Fig. 6-8 zeigen Zuschnitte 10, bevor mit den Zuschnitten 10 die jeweiligen Zigarettengruppen bzw. Zigarettenformationen 27 unter Bildung der Innenumhüllung eingehüllt werden. Solche Zuschnitte 10, auch Innenliner-Zuschnitte genannt, sind an sich bekannt. Einzelheiten derselben sind beispielsweise in der EP 1 016 593 A1 offenbart, deren Inhalt in die vorliegende Anmeldung integriert wird.The Fig. 6-8 show blanks 10 before the respective cigarette groups or cigarette formations 27 are wrapped with the blanks 10 to form the inner sheath. Such blanks 10, also called inner liner blanks, are in themselves known. Details thereof are for example in the EP 1 016 593 A1 discloses the content of which is incorporated into the present application.

Der Zuschnitt 10 verfügt über Bodenwand 11, Vorderwand 12, Rückwand 13, Stirnfaltlappen 14, 15, die eine gegenüberliegende, obere Stirnwand bilden, sowie Seitenfaltlappen 16 und 17, die schmale Seitenwände bilden. Im Bereich der Vorderwand 12 ist eine quergerichtete Perforation 18 angebracht, die einen stirnseitigen Bereich des Zuschnitts 10 begrenzt und als sogenannter Flap dient, der bei erstmaliger Ingebrauchnahme der Packung durch Erfassen des Stirnwandlappens 14 abgezogen wird. Obwohl der Zuschnitt 10 aus dünnem Verpackungsmaterial besteht, ist er mit Prägelinien versehen, nämlich mit zwei parallelen, quergerichteten Querprägelinien 19, 20, die die Bodenwand 11 gegenüber Vorderwand 12 und Rückwand 13 begrenzen. Die Querprägelinien 19, 20 bilden bodenseitige Faltkanten. Weiter sind in Längsrichtung des Zuschnitts 10 verlaufende Längsprägelinien 21 und 22 vorhanden, die die streifenförmigen Seitenfaltlappen 16 bzw. 17 gegenüber dem übrigen Teil des Zuschnitts 10 abgrenzen. Auch die Längsprägelinien 21 und 22 dienen als Faltkanten. Weiter weist der Zuschnitt 10 noch Bodenfaltlappen 24 auf und neben diesen angeordnete Faltwickel 25. Diese sind voneinander durch Faltlinien 26 getrennt.The blank 10 has bottom wall 11, front wall 12, rear wall 13, front fold tabs 14, 15 forming an opposite upper end wall, and side folding tabs 16 and 17 forming narrow side walls. In the area of the front wall 12, a transverse perforation 18 is provided, which delimits an end region of the blank 10 and serves as a so-called flap, which is removed by grasping the end wall flap 14 when the package is used for the first time. Although the blank 10 is made of thin packaging material, it is provided with stamping lines, namely with two parallel transverse transverse stamping lines 19, 20 bounding the bottom wall 11 opposite the front wall 12 and rear wall 13. The transverse stamping lines 19, 20 form bottom fold edges. Further extending in the longitudinal direction of the blank 10 longitudinal longitudinal lines 21 and 22 are present, which delimit the strip-shaped Seitenfaltlappen 16 and 17 relative to the remaining part of the blank 10. The Längsprägelinien 21 and 22 serve as folding edges. Next, the blank 10 still floor folding tabs 24 and arranged next to this folding wrap 25. These are separated from each other by fold lines 26.

Die mit den Zuschnitten 10 zu umhüllenden Zigarettengruppen 27 werden mittels eines Zigarettenförderers 28 mit in gleichen Abständen voneinander beabstandeten Mitnehmern 29 entlang eines Zuschnittaggregats 30 gefördert.The cigarette groups 27 to be wrapped with the blanks 10 are conveyed along a cut-to-size unit 30 by means of a cigarette conveyor 28 with drivers 29 spaced at equal intervals from one another.

Im Bereich des Zuschnittaggregats 30 werden die Zuschnitte 10 nacheinander zugeführt und zur Übernahme durch eine Zigarettengruppe 27 bereitgehalten. Die Zuschnitte 10 werden dabei von einer fortlaufenden Materialbahn 31 aus Papier, Stanniol oder anderem Verpackungsmaterial durch ein Trennorgan 32 abgetrennt und in einer Position quer zur Bewegungsrichtung der Zigarettengruppen 27 als "Vorhang" bereitgehalten.In the area of the trimming unit 30, the blanks 10 are fed one after the other and kept ready for takeover by a group of cigarettes 27. The blanks 10 are separated from a continuous web of paper 31, Stanniol or other packaging material by a separating member 32 and held in a position transverse to the direction of movement of the cigarette groups 27 as a "curtain".

Der Zuschnitt 10 wird im Bereich des Zuschnittaggregats 30 so positioniert, dass die Zigarettengruppe 27 mit in Förderrichtung vorn liegenden Endflächen, im vorliegenden Fall mit den filterfreien Zigarettenenden, den Zuschnitt 10 im Bereich seiner Bodenwand 11 erfassen, nämlich zwischen den beiden Querprägelinien 19, 20. Bei Fortsetzung der Förderbewegung der Zigarettengruppe 27 wird der Zuschnitt U-förmig gefaltet. Im Bereich des Zuschnittaggregats 30 ist zu diesem Zweck ein nicht dargestelltes Mundstück angeordnet mit entsprechenden Führungen oberhalb und unterhalb der Bewegungsbahn der Zigarettengruppe 27.The blank 10 is positioned in the region of the trimming unit 30 so that the group of cigarettes 27 with end surfaces lying forward in the conveying direction, in the present case with the filter-free cigarette ends, grasp the blank 10 in the region of its bottom wall 11, namely between the two transverse stamping lines 19, 20. Upon continuation of the conveying movement of the cigarette group 27, the blank is folded in a U-shape. In the area of the cutting unit 30, a mouthpiece, not shown, is arranged for this purpose with corresponding guides above and below the movement path of the cigarette group 27.

Das Trennorgan 32 umfasst eine rotierend angetriebene Messerwalze 33, die mithilfe eines auf deren Umfangsfläche angebrachten Trennmessers 34a, das mit einem ortsfesten Trennmittel 34b zusammenwirkt, die fortlaufende Materialbahn 31 in die einzelnen Zuschnitte 10 trennt.The separating member 32 comprises a rotatingly driven knife roller 33, which separates the continuous material web 31 into the individual blanks 10 by means of a separating knife 34a, which is mounted on its peripheral surface and interacts with a stationary separating agent 34b.

Mit einem Perforationsmesser 35 bringt die Messerwalze 33 die Perforationslinie 18 in den Zuschnitt 10 ein.With a Perforationsmesser 35 brings the knife roller 33, the perforation 18 in the blank 10 a.

Zum Einbringen der Querprägelinien 19, 20 verfügt das Zuschnittaggregat 30 über eine Prägewalze 36, auf deren Umfang die Prägewerkzeuge angebracht sind, nämlich zwei quergerichtete, rippenartige Prägenoppen 37. Die Prägewalze 36 ist bezogen auf die Förderrichtung stromab der Messerwalze 33 angeordnet. Entsprechend werden die Querprägelinien 19, 20 an der Materialbahn 31 angebracht, wobei während des Prägevorgangs eine Andrückwalze 38 als Gegendruckorgan am Umfang der Prägewalze 36 bzw. an der Materialbahn 31 anliegt.For introducing the transverse stamping lines 19, 20, the blanking unit 30 has an embossing roller 36, on the circumference of the embossing tools are mounted, namely two transverse, rib-like embossing nubs 37. The embossing roller 36 is located downstream of the knife roller 33 relative to the conveying direction. Correspondingly, the transverse stamping lines 19, 20 are attached to the material web 31, wherein during the embossing process a pressure roller 38 bears against the circumference of the embossing roll 36 or against the material web 31 as a counterpressure element.

Nicht gezeigt ist ein weiteres, stromauf angeordnetes Prägeaggregat, mit dem die Längsprägelinien 21, 22 in die Materialbahn 31 angebracht werden.Not shown is another, upstream arranged embossing unit, with which the Längsprägelinien 21, 22 are mounted in the web 31.

Die von der Materialbahn 31 abgetrennten Zuschnitte 10 werden von der Messerwalze 33 an drehende Saugscheiben 39 übergeben. Die Saugscheiben 39 sind längs des Umfangs mit Saugbohrungen 40 versehen und erfassen den Zuschnitt 10 an seitlichen Rändern. Zur Führung des Zuschnitts während dieser Saug-/Dreh-Förderbewegung ist ein Leitorgan 41 vorgesehen, nämlich ein Leitblech, auf dem der Zuschnitt 10 mindestens bereichsweise aufliegt. Die Zigarettengruppen 27 sind zwischen den Saugscheiben 39 hindurchförderbar, wobei der Zuschnitt 10 im Bereich der Bodenwandung 11 von der Zigarettengruppe 27 erfasst und von den Saugscheiben 39 abgezogen wird.The blanks 10 cut off from the material web 31 are transferred by the knife roller 33 to rotating suction disks 39. The suction discs 39 are provided along the circumference with suction holes 40 and detect the blank 10 at lateral edges. To guide the blank during this suction / rotary conveying movement, a guide member 41 is provided, namely a baffle on which the blank 10 rests at least partially. The cigarette groups 27 can be conveyed through between the suction discs 39, the blank 10 being grasped by the cigarette group 27 in the region of the bottom wall 11 and drawn off by the suction discs 39.

Eine wichtige Besonderheit ist, dass auf die - kontinuierlich oder taktweise angetriebene - Materialbahn 31 stromauf des Trennorgans 32 im vorliegenden Fall raupenförmige Aromastoffportionen 42 aufgebracht werden, im vorliegenden Fall Menthol.An important feature is that caterpillar-shaped flavoring portions 42 are applied to the material web 31, which is driven continuously or cyclically, upstream of the separating member 32 in the present case, in this case menthol.

Diese Aromastoffportionen 42 werden auf die nachfolgend als Innenseite 43 bezeichnete Seite der Materialbahn 31 aufgebracht, die im späteren eingehüllten Zustand der Zigarettengruppe 27 nach innen zeigt, das heißt zur Zigarettengruppe 27. Hierdurch wird gewährleistet, dass der (flüchtige) Aromastoff in die einzelnen Zigaretten der Zigarettengruppe 27 übergehen kann, während diese in der Zigarettenpackung angeordnet sind.These aroma substance portions 42 are applied to the side of the material web 31 designated below as the inner side 43, which faces the cigarette group 27 in the later wrapped state, that is to the cigarette group 27. This ensures that the (volatile) flavoring substance in the individual cigarettes of the Cigarette Group 27 can go over while they are arranged in the cigarette pack.

Zur Aufbringung der Aromastoffportionen 42 ist der Innenseite 43 der Materialbahn 31 ein Auftragsorgan 44 zugeordnet. Das Auftragsorgan 44 umfasst im vorliegenden Fall mehrere (vier), nebeneinander angeordnete Ventile 45a-d mit Düsen 62 mit Ventil- bzw. Düsenöffnungen 52, mit denen parallele Reihen bzw. Bahnen 46a-d von einzelnen Aromastoffportionen 42 aufgebracht werden können.For application of the flavoring agent portions 42, the inner side 43 of the material web 31 is assigned an application member 44. In the present case, the application member 44 comprises a plurality of (four), juxtaposed valves 45a-d with nozzles 62 having valve or nozzle openings 52, with which parallel rows or webs 46a-d of individual flavoring agent portions 42 can be applied.

In den Fig. 3-5 ist eine besondere Ausführungsform der Erfindung gezeigt. Die Unterschiede betreffen insbesondere, aber nicht ausschließlich die Ausbildung der Ventile 45a-d eines Auftragsorgans 44, die gegenüber den Ventilen 45a-d der Ausführungsform gemäß Fig. 1, von denen nur das vordere Ventil 45a zu sehen ist, später noch näher erläuterte Besonderheiten aufweisen.In the Fig. 3-5 a particular embodiment of the invention is shown. The differences relate in particular, but not exclusively, to the formation of the valves 45a-d of an applicator 44, which are opposite to the valves 45a-d of the embodiment according to FIG Fig. 1 , of which only the front valve 45a can be seen, later explained in more detail have special features.

Insofern nicht explizit auf Unterschiede der einzelnen Ausführungsformen eingegangen wird, gelten die nachfolgenden Erläuterungen für beide Ausführungsformen.Insofar as no explicit reference is made to differences between the individual embodiments, the following explanations apply to both embodiments.

Gemäß der Ausführungsform der Fig. 1, 2 sind die Leimventile 45a-d mit geringem Abstand von der Materialbahn 31 angeordnet, vorliegend oberhalb derselben.According to the embodiment of the Fig. 1 . 2 the glue valves 45a-d are arranged at a small distance from the material web 31, in the present case above the same.

Um zu verhindern, dass die Aromastoffportionen 42 die nachfolgenden Aggregate verunreinigen, insbesondere das Trennorgan 32, ist bei dieser Ausführungsform stromab des Auftragsorgans 44 ein Bearbeitungsmittel 47 angeordnet, in diesem Fall eine Umlenkwalze 47a.In order to prevent the flavoring agent portions 42 from contaminating the subsequent aggregates, in particular the separating member 32, a processing means 47, in this case a deflecting roll 47a, is arranged downstream of the application member 44 in this embodiment.

Die Materialbahn 31 wird entlang dem Bearbeitungsmittel 47 geführt, nämlich derart, dass deren Innenseite 43 mit den darauf aufgebrachten Aromastoffportionen 42 während des Umlenkvorgangs an der Umfangsfläche der Umlenkwalze 47 anliegt. Die Breite der Umlenkwalze bzw. der Umfangsfläche der Umlenkwalze 47 ist dabei derart an die Materialbahn 31 bzw. an das Auftragsbild der einzelnen Aromastoffportionen 42 auf der Materialbahn 31angepasst, dass sämtliche Portionen 42 bzw. sämtliche parallelen Reihen 46a-d von Portionen 42, vgl. Fig. 6-8, durch die Umlenkwalze 47 flachgedrückt werden. Zu diesem Zweck wird die Materialbahn 31 unter einer gewissen Spannung entlang der Umlenkwalze 47 geführt. Infolge des Flachdrückens der Portionen 42 verbreitern sich diese etwas gegenüber dem Zustand vor dem Flachdrücken, vgl. Fig. 6.The material web 31 is guided along the processing means 47, namely in such a way that its inner side 43, with the aroma substance portions 42 applied thereto, bears against the peripheral surface of the deflection roller 47 during the deflection process. The width of the deflection roller or peripheral surface of the deflection roller 47 is adapted to the material web 31 or to the application pattern of the individual flavoring agent portions 42 on the material web 31 such that all portions 42 or all parallel rows 46a-d of portions 42, cf. Fig. 6-8 be flattened by the guide roller 47. For this purpose, the material web 31 is guided at a certain tension along the deflection roller 47. As a result of the flat pressing of the portions 42, these widen somewhat compared to the state before flattening, cf. Fig. 6 ,

Die Umfangslänge der rotierenden Umlenkwalze 47 ist an die Länge der jeweils von der Materialbahn 31 abzutrennenden Zuschnitte 10 angepasst. Sie entspricht vorliegend dieser Länge. Entsprechend berühren dieselben Bereiche der Walze 47 jeweils dieselben Bereiche der jeweiligen Zuschnitte 10 bzw. der auf den Zuschnitten 10 angeordneten Aromastoffportionen 42. Sollten sich von den Aromastoffportionen 42 gewisse Anteile im Verlaufe der Produktion auf die Walze 47 übertragen, lagern sich diese nur an bestimmten Positionen der Walze 47 ab. Mit anderen Worten würde jeder Zuschnitt 10, von dem sich Aromastoffanteile auf die Walze 47 übertragen, seine Anteile auf dieselben Walzenbereiche bzw. Walzenpositionen übertragen.The circumferential length of the rotating deflection roller 47 is adapted to the length of the blanks 10 to be separated from the material web 31 in each case. In the present case, it corresponds to this length. Accordingly, the same areas of the roller 47 each contact the same areas of the respective blanks 10 and arranged on the blanks 10 Aromastoffportionen 42. Should be transferred from the flavoring portions 42 certain shares in the course of production on the roller 47, these store only at certain positions the roller 47 from. In other words, each blank 10 from which flavoring ingredients are transferred to the roller 47 would transfer its portions to the same roller areas.

In der Folge würde die Walze 47 das auf ihrer Umfangsfläche entstehende Ablagerungsbild immer auf dieselben Stellen der später folgenden Zuschnitte 10 der fortlaufenden Materialbahn 31 übertragen. Im Optimalfall wäre das Ablagerungsbild auf der Walze 47 derart, dass die Übertragung der Ablagerungen auf die folgenden Zuschnitte 10 nur an denjenigen Stellen des jeweiligen Zuschnitts 10 erfolgt, an denen sich ohnehin Aromastoffportionen 42 befinden.As a result, the roller 47 would always transfer the deposited image formed on its peripheral surface to the same locations of the subsequent blanks 10 of the continuous material web 31. In the optimal case, the deposit image on the roller 47 would be such that the transfer of the deposits to the subsequent blanks 10 takes place only at those points of the respective blank 10 at which flavoring portions 42 are present anyway.

Im Unterschied zu der Ausführungsform gemäß Fig. 1, 2 kann in der Ausführungsform gemäß den Fig. 3, 4 und 5 auf die Verwendung einer Umlenkwalze als Bearbeitungsmittel 47 verzichtet werden. Anstelle der Umlenkwalze wird eine Leiste 61 verwendet, die unmittelbar nach der Aufbringung der Portionen 42 die einzelnen Portionen 42 flachstreicht.Unlike the embodiment according to Fig. 1 . 2 can in the embodiment according to the Fig. 3 . 4 and 5 to dispense with the use of a guide roller as a processing means 47. Instead of the guide roller, a strip 61 is used, which flattens the individual portions 42 immediately after the application of the portions 42.

Die Leiste 61 erstreckt sich quer zur Materialbahn 31, und zwar wie bei der Lösung mit Umlenkwalze 47 unter Erzeugung einer gewissen Materialbahnspannung, vgl. Fig. 5. Die Leiste 61 ist als Keramikleiste ausgebildet und beheizt, um Aromastoffablagerungen an der Leiste zu verhindern. Im vorliegenden Fall ist sie unmittelbar an dem Auftragsorgan 44 angeordnet.The strip 61 extends transversely to the material web 31, and indeed as in the solution with deflection roller 47 to produce a certain web tension, see. Fig. 5 , The strip 61 is formed as a ceramic strip and heated to prevent flavor deposits on the bar. In the present case, it is arranged directly on the applicator 44.

Genauer gesagt ist sie Teil jeder Austrittsdüse 62 jedes Ventils 45a-d. Die Leiste 61 bildet dabei eine Wandung 62a jeder Düse 62. Eine in Förderrichtung hintere Seite 64a der Leiste 61 bildet dabei jeweils eine der Innenseiten der die Düsenaustrittsöffnungen 52 begrenzenden Düsenwandungen. Eine der weiteren Düsenwandungen ist in Fig. 5 erkennbar, nämlich die der Wandung 62a gegenüberliegende Düsenwandung 62b mit entsprechender Innenseite 64b.More specifically, it is part of each outlet nozzle 62 of each valve 45a-d. In this case, the strip 61 forms a wall 62a of each nozzle 62. A rear side 64a of the strip 61 in the conveying direction in each case forms one of the inner sides of the nozzle walls defining the nozzle outlet openings 52. One of the other nozzle walls is in Fig. 5 recognizable, namely the wall 62a opposite nozzle wall 62b with corresponding inner side 64b.

Im durch die Düsenwandungen bzw. durch deren entsprechende Innenseiten umschlossenen Raum befindet sich der flüssige Aromastoff, bevor er auf die Materialbahn 31 aufgetragen wird.In the space enclosed by the nozzle walls or by their corresponding inner sides, the liquid flavoring substance is present before it is applied to the material web 31.

Schließlich ist vorgesehen, dass das Auftragsorgan 44 gemäß der Fig. 3-5 aus einer Arbeitsstellung, in der die Kontaktleiste der Kontaktdüse 62 die Materialbahn 31 unter Spannung berührt, in eine Ruhestellung verschwenkbar ist, vgl. den gestrichelten Umriss des Auftragsorgans 44 in Fig. 3.Finally, it is provided that the application member 44 according to the Fig. 3-5 from a working position, in which the contact strip of the contact nozzle 62 touches the material web 31 under tension, is pivotable into a rest position, cf. the dashed outline of the applicator 44 in Fig. 3 ,

Bei beiden beschriebenen Ausführungsformen der Erfindung entstammt der Aromastoff (das Menthol), der mithilfe des Auftragsorgans 44 auf die Materialbahn 31 aufgetragen wird, einem Aromastoffreservoir 48. Aus dem Reservoir 48 wird der flüssige Aromastoff über eine oder mehrere Leitungen 49 (beispielsweise Schlauchleitungen) dem Auftragsorgan 44 zugeführt, insbesondere den Ventilen 45a-d desselben.In both described embodiments of the invention, the flavor (menthol) applied to the web 31 by the applicator 44 is derived from a flavor reservoir 48. From the reservoir 48, the liquid flavor is delivered to the applicator via one or more conduits 49 (eg, tubing) 44 supplied, in particular the valves 45 a-d thereof.

Die Signale, mit Hilfe derer das Auftragsorgan 44 zur Abgabe der einzelnen Portionen 42 gesteuert wird, entstammen einer Steuerung 50, an die das Auftragsorgan 44 mit einer oder mehreren Signalleitungen 51 angeschlossen ist. Letztlich steuert die Steuerung 50 die Öffnung eines Verschlussorgans 51 in dem jeweiligen Ventil 45a-d, das im verschlossenen Zustand des jeweiligen Ventils 45a-d die jeweilige Düsenöffnung 52 verschließt und im geöffneten Zustand freigibt.The signals by means of which the applicator 44 is controlled to dispense the individual portions 42 come from a controller 50 to which the applicator 44 is connected to one or more signal lines 51. Finally, the controller 50 controls the opening of a closure member 51 in the respective valve 45a-d, which closes the respective nozzle opening 52 in the closed state of the respective valve 45a-d and releases it in the opened state.

Die Erzeugung der einzelnen Portionen 42 erfolgt in besonderer Weise derart, dass die Gesamtmenge der pro Zuschnitt 10 auf die Materialbahn 31 aufgebrachten Einzelportionen 42 unabhängig ist von der Maschinengeschwindigkeit der Vorrichtung bzw. von der Materialbahngeschwindigkeit. Mit anderen Worten wird das Auftragsorgan 44 bzw. werden die einzelnen Ventile 45a-d des Auftragsorgans 44 so gesteuert, dass jeweils die Gesamtmenge Aromastoff, der auf den jeweiligen Zuschnitt 10 der Materialbahn 31 aufgebracht wird, unabhängig von der Materialbahngeschwindigkeit/Maschinengeschwindigkeit konstant ist. Dies geschieht in der Regel dadurch, dass die Öffnungszeiten der Ventile 45a-d an die jeweilige Maschinen- bzw. Bahngeschwindigkeit angepasst werden.The generation of the individual portions 42 takes place in a special manner such that the total amount of individual portions 42 applied to the material web 31 per blank 10 is independent of the machine speed of the apparatus or of the material web speed. In other words, the application member 44 or the individual valves 45a-d of the application member 44 are controlled so that in each case the total amount of flavoring agent applied to the respective blank 10 of the material web 31 is constant, independent of the material web speed / machine speed. This is usually done by adjusting the opening times of the valves 45a-d to the respective machine or web speed.

Weiter ist vorgesehen, dass bei identischer Gesamtportionsmenge pro Zuschnitt 10 die Anzahl von Einzelportionen 42, die auf einen Zuschnitt 10 aufgebracht werden, nach Maßgabe der Maschinengeschwindigkeit der Verpackungsmaschine und/oder der Materialbahngeschwindigkeit eingestellt ist bzw. abhängig davon ist.It is further provided that with identical total portion quantity per blank 10, the number of individual portions 42 which are applied to a blank 10 is set according to the machine speed of the packaging machine and / or the web speed or depends on it.

Beispielsweise kann vorgesehen sein, dass bei einer ersten, niedrigeren Maschinen- und/oder Materialbahngeschwindigkeit pro Zuschnitt 10 mehr Einzelportionen auf die Materialbahn 31 aufzubringen sind als bei einer zweiten, höheren Geschwindigkeit. Hierdurch könnte eine zu große Anhäufung von Aromastoff auf ein und derselben Stelle bei niedrigerer Maschinen- bzw. Materialbahngeschwindigkeit verhindert werden.For example, it may be provided that at a first, lower machine and / or material web speed per blank 10 more individual portions are to be applied to the material web 31 than at a second, higher speed. As a result, an excessive accumulation of flavoring could be prevented in the same place at lower machine or material web speed.

In Fig. 6 ist das Auftragsbild der einzelnen Aromaportionen 42 eines Zuschnitts 10 gezeigt. Dieses Auftragsbild entspricht einer zweiten, höheren Maschinen- und/oder Bahngeschwindigkeit als das Auftragsbild des Zuschnitts 10 der Fig. 7.In Fig. 6 the application image of the individual flavor portions 42 of a blank 10 is shown. This application pattern corresponds to a second, higher machine and / or web speed than the application pattern of the blank 10 of FIG Fig. 7 ,

In Fig. 8 ist ein Auftragsbild gezeigt, bei dem die Geschwindigkeit der Materialbahn bzw. die Maschinengeschwindigkeit nochmals höher eingestellt ist
als bei der Variante der Fig. 6. Bei identischer Öffnungszeit der Ventile 45a-d des Auftragsorgans 44 entstehen entsprechend längere Aromastoffportionen 42.
In Fig. 8 an order picture is shown in which the speed of the material web or the machine speed is set even higher
as in the variant of Fig. 6 , With an identical opening time of the valves 45a-d of the application member 44, correspondingly longer flavoring portions 42 are produced.

Eine weitere Besonderheit der Steuerung des Auftragsvorgangs ist, dass bevorzugt die Bereiche des Zuschnitts 10 ausgespart, das heißt nicht mit Portionen 42 belegt werden, die nach der späteren Umhüllung der Zigarettengruppen 27 die Filter der Zigaretten von vorne, seitlich und von oben überdecken. In Fig. 6 bis 8 sind hierzu die Stirnfaltlappen 14, 15 ausgespart, die die Zigarettenfilter von oben bzw. endseitig überdecken. Weiter sind die Bereiche ausgespart, die die Filter der Zigaretten vorne und seitlich überdecken.A further special feature of the control of the application process is that preferably the areas of the blank 10 are recessed, that is not covered with portions 42, which cover the filters of the cigarette groups from the front, side and from the top after the later wrapping of the cigarette groups 27. In Fig. 6 to 8 For this purpose, the Stirnfaltlappen 14, 15 are recessed, which cover the cigarette filter from above or end. Furthermore, the areas are left out, which cover the filter of the cigarette front and side.

Durch die Querlinien 53 in den Fig. 6-8 sind jeweils die Zeitpunkte visualisiert, zu denen die jeweiligen Ventile 45a-d geöffnet werden. In der Variante der Fig. 7 werden zur Erzeugung der doppelten Anzahl von Portionen 42 die Ventile zusätzlich zwischen zwei Zeitpunkte 53 ein weiteres Mal geöffnet.Through the cross lines 53 in the Fig. 6-8 each time points are visualized, to which the respective valves 45a-d are opened. In the variant of Fig. 7 In order to generate the double number of portions 42, the valves are additionally opened between two times 53 again.

Um die Materialbahngeschwindigkeit zu erfassen, ist der Messerwalze 33 ein Drehgeber 54 zugeordnet, der die Drehzahl der Messerwalze 33 erfasst. Die Signale des Drehgebers 54 werden über eine Signalleitung 55 an die Steuerung 50 übertragen. Aus den Drehzahlen der Messerwalze 33 errechnet die Steuerung 50 die Materialbahngeschwindigkeit.To detect the material web speed, the knife roller 33 is associated with a rotary encoder 54 which detects the rotational speed of the knife roller 33. The signals of the rotary encoder 54 are transmitted to the controller 50 via a signal line 55. From the rotational speeds of the knife roller 33, the controller 50 calculates the material web speed.

Um zu verhindern, dass sich auf einzelnen Organen, die mit dem Aromastoff in Berührung kommen, Aromstoffablagerungen bilden, sind diese Organe gemäß einer weiteren Besonderheit beheizt bzw. beheizbar.In order to prevent flavor deposits from forming on individual organs that come into contact with the flavoring agent, these organs are heated or heated according to another feature.

So sind beispielsweise die Umlenkwalze 47, das Auftragsorgan 44 bzw. die einzelnen Ventile 45a-d, das Reservoir 48 sowie die Leitungen 49 mit entsprechenden Heizorganen, insbesondere Heizdrähten, ausgestattet, die über geeignete Stromleitungen 57 mit einem zentralen Heizaggregat 58 verbunden sind. Das Heizaggregat 58 umfasst unter anderem eine notwendige Spannungsquelle zur Versorgung der Heizorgane. Zum anderen umfasst das Heizaggregat eine geeignete Heizregelung, die über eine Leitung 59 zudem mit der Steuerung 50 verbunden ist.Thus, for example, the guide roller 47, the application member 44 and the individual valves 45a-d, the reservoir 48 and the lines 49 with corresponding heating elements, in particular heating wires, equipped, which are connected via suitable power lines 57 to a central heating unit 58. The heating unit 58 includes, inter alia, a necessary voltage source for supplying the heating elements. On the other hand, the heating unit includes a suitable heating control, which is also connected via a line 59 to the controller 50.

Eine weitere Besonderheit ist ein Sensor 60, der über eine Signalleitung 55 mit der Steuerung 50 verbunden ist. Mit Hilfe dieses Sensors 60 können ein oder mehrere charakteristische Merkmale der auf die Materialbahn 31 aufgebrachten Portionen 42 erfasst und in der Steuerung 50 zur Prüfung ausgewertet werden. Konkret handelt es sich im vorliegenden Fall um einen Glanzsensor 60, der Glanzwerte der einzelnen Portionen 42 erfasst. Sollten die erfassten Glanzwerte von bestimmten, vorgegebenen Sollwerten abweichen, wird in der Steuerung 50 ein Fehlersignal erzeugt. Ggf. wird die Verpackungsmaschine abgeschaltet werden.Another special feature is a sensor 60, which is connected via a signal line 55 to the controller 50. With the aid of this sensor 60, one or more characteristic features of the portions 42 applied to the material web 31 can be detected and evaluated in the controller 50 for testing. Specifically, in the present case, it is a gloss sensor 60 which records gloss values of the individual portions 42. If the detected gloss values deviate from certain, predetermined setpoint values, an error signal is generated in the controller 50. Possibly. the packaging machine will be switched off.
