  • a) the blank has two longitudinal, continuous longitudinal embossing lines, by means of which a central region of the blank, consisting of bottom wall, front wall, rear wall and end flaps, is delimited from folding flaps arranged on both sides, namely side folding flaps and bottom folding flaps,
  • b) the transverse embossing lines extend exclusively between the longitudinal embossing lines,
  • c) the area of the side folding flaps and the bottom folding flaps is free from embossed lines.

    • Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung werden durch die Merkmale der Ansprüche 2 und 3 gekennzeichnet.The method according to the invention and the device according to the invention are characterized by the features of claims 2 and 3.

    Zunächst sind vorgeformte bzw. vorgeprägte Faltlinien, nämlich zwei Längsprägelinien, zur Abgrenzung eines mittleren, durchgehenden Bereichs des Zuschnitts von seitlichen Faltlappen vorgesehen. Alle Faltlappen werden erfindungsgemäß an einer fortlaufenden Materialbahn zum Herstellen der Zuschnitte angebracht, wobei die Längsprägelinien als durchgehende Prägelinien in Längsrichtung der Materialbahn ausgebildet sind.First there are pre-formed or pre-embossed fold lines, namely two longitudinal embossing lines, to delimit a central, continuous area of the cut from lateral Folding flaps provided. According to the invention, all folding flaps are arranged on a continuous Material web attached to produce the blanks, the longitudinal embossing lines as continuous embossing lines are formed in the longitudinal direction of the material web.

    Weiterhin sind von der Zigarettengruppe bzw. von den in Förderrichtung vomliegenden Zigarettenenden erfasste Bereiche des Zuschnitts, nämlich die Bodenwand, durch vorgeformte bzw. vorgeprägte, in Bezug auf die Längsrichtung der Materialbahn quergerichtete Faltlinien, gegenüber einer Vorderwand und einer Rückwand des Zuschnitts abgegrenzt, so dass hier die auftretende mechanische Belastung auf Grund der Faltung des Zuschnitts reduziert ist. Die quergerichteten Faltlinien sind als Querprägelinien ausgebildet, die sich ausschließlich im Bereich zwischen den Längsprägelinien und nicht im Bereich der seitlichen Faltlappen des Zuschnitts erstrecken, zumal dort ein anderes, komplexes Faltbild durch Bodenfaltlappen und Faltzwickel vorhanden ist.Furthermore, of the cigarette group or of those lying in the conveying direction Areas of the blank that are cigarette ends, namely the bottom wall, are formed by preformed ones or pre-embossed, transverse in relation to the longitudinal direction of the material web Fold lines, delimited from a front wall and a rear wall of the blank, so that here the occurring mechanical load due to the folding of the Cutting is reduced.

    Der Zuschnittstation 28 ist ein Zuschnittaggregat 33 zugeordnet. Diesem wird die Materialbahn 29 - von einer Bobine 34 kommend - zugeführt. Der Zuschnitt 10 wird durch ein Trennaggregat, nämlich durch eine Messerwalze 35 mit Trennmesser 46 von der Materialbahn 29 abgetrennt und der jeweiligen Zigarettengruppe 23 zugeführt. Die Messerwalze 35 ist auch mit einem Perforationsmesser 36 ausgerüstet zum Herstellen der Perforationslinie 18.A cutting unit 33 is assigned to the cutting station 28. This is the material web 29 - coming from a bobbin 34 - fed. The blank 10 is cut by a separating unit, namely by a knife roller 35 with cutting knife 46 from the material web 29 separated and the respective cigarette group 23 supplied. The knife roller 35 is also with a perforation knife 36 equipped for making the perforation line 18th

    Das Zuschnittaggregat 33 weist ein Prägeorgan auf zum Anbringen der Querprägelinie 19, 20. Es handelt sich dabei um eine Prägewalze 37. Auf dem Umfang derselben sind Prägewerkzeuge angebracht, nämlich zwei quergerichtete rippenartige Prägenoppen 38. Die Prägewalze 37 ist der Messerwalze 35 in Förderrichtung vorgeordnet. Die Querprägelinien 19, 20 werden demnach an der Materialbahn 29 angebracht. Ein Gegendruckorgan, nämlich eine (bewegbare) Andrückwalze 39, liegt mindestens während der Prägung am Umfang der Prägewalze 37 bzw. an der Materialbahn 29 an. Die Andrückwalze 39 ist taktweise bewegbar, z.B. über eine Kurbel, und besteht mindestens teilweise aus elastischem Werkstoff, z.B. Vulkolan. Der Prägewalze 37 ist eine Umlenkwalze 40 vorgeordnet, die einen großen Umschlingungswinkel auf der Prägewalze 37 erzeugt.The cutting unit 33 has an embossing member for attachment the cross embossing line 19, 20. It is an embossing roller 37. Embossing tools are attached to the circumference thereof, namely two transverse rib-like embossing knobs 38. The embossing roller 37 is the knife roller 35 in the conveying direction upstream. The cross embossing lines 19, 20 are accordingly on the Material web 29 attached. A counter pressure element, namely one (movable) pressure roller 39 lies at least during the embossing on the circumference of the embossing roller 37 or on the material web 29 on. The pressure roller 39 can be moved in cycles, e.g. over a Crank, and consists at least partially of elastic material, e.g. Vulkolan. The embossing roller 37 is a deflection roller 40 preceded by a large wrap angle on the embossing roller 37 generated.

    Die Längsprägelinien 21, 22 werden in der Materialbahn 29 durch ein eigenständiges Prägeaggregat hergestellt, welches bei dem vorliegenden Ausführungsbeispiel in Transportrichtung dem Zuschnittaggregat 33 vorgeordnet ist. Ein separat angeordnetes Prägeaggregat 49 weist zwei ständig aneinander liegende Prägewalzen 55, 56 auf, von denen eine - z.B. die Prägewalze 55 - zwei ringsherum laufende, ringförmige Prägerippen (nicht gezeigt) aufweist entsprechend der Position der Längsprägelinien 21, 22. Die andere Prägewalze 56 kann als Andrückwalze dienen, vorzugsweise ebenfalls mit elastischem Mantel. Die durch das Prägeaggregat 49 fortlaufend geprägte Materialbahn wird über Umlenk- und Führungswalzen dem beschriebenen Zuschnittaggregat 33 zugeführt.The longitudinal embossing lines 21, 22 are through in the material web 29 an independent embossing unit manufactured, which in the present embodiment in the transport direction of the cutting unit 33 is upstream. A separately arranged Embossing unit 49 has two embossing rollers which are constantly adjacent to one another 55, 56, one of which - e.g. the embossing roller 55 - two circular embossing ribs running around (not shown) has according to the position of the longitudinal embossing lines 21, 22. The other embossing roller 56 can serve as a pressure roller, preferably also with an elastic jacket. The through that Embossing unit 49 continuously embossed material web is over Deflection and guide rollers the cutting unit described 33 fed.

    Eine Besonderheit besteht darin, dass das Zuschnittaggregat 33, einschließlich Prägeorgan, eigenständig angetrieben ist, also nicht durch zentralen Antrieb der Verpackungsmaschine, jedoch in Abstimmung mit diesem. Dem Zuschnittaggregat 33 ist ein Motor zugeordnet, nämlich ein Servomotor 41. Dieser treibt ein zentrales Antriebsrad an.A special feature is that the cutting unit 33, including embossing organ, is driven independently, so not through the central drive of the packaging machine, however in coordination with this. The cutting unit 33 is a motor assigned, namely a servomotor 41. This drives central drive wheel.

    Der Antrieb des Zuschnittaggregats 33 wird in Abhängigkeit von der Position der zugeführten Zigarettengruppen 23 gesteuert. The drive of the cutting unit 33 is dependent on the position of the supplied cigarette groups 23 controlled.

    Durch diese Maßnahme wird erreicht, dass der Zuschnitt 10 in einer exakten Relativstellung - hinsichtlich der Querprägelinie 19, 20 - für die Übernahme durch die Zigarettengruppe 23 bereitgehalten wird. Oberhalb der Förderbahn für die Zigarettengruppe 23 ist ein Tastorgan angeordnet, nämlich ein optoelektronischer Sensor 47. Dieser tastet mit einer Lichtschranke die Vorderseite einer Zigarettengruppe 23 ab und steuert den Servomotor 41 und damit die Zuführung des Zuschnitts 10 in exakter Übereinstimmung mit den tatsächlich ankommenden Zigarettengruppen 23. Werden demnach keine Zigarettengruppen dem Zuschnittaggregat 33 zugeführt und durch den Sensor 47 erkannt, wird auch die Zufuhr des Verpackungsmaterials gestoppt.This measure ensures that the blank 10 in an exact relative position - with regard to the cross stamping line 19, 20 - for takeover by cigarette group 23 is kept ready. Above the conveyor for the cigarette group 23 is a sensing element, namely an optoelectronic one Sensor 47. This probes with a light barrier the front of a group of cigarettes 23 and controls the Servomotor 41 and thus the feeding of the blank 10 in exact correspondence with the actually arriving cigarette groups 23. If there are no cigarette groups Cutting unit 33 fed and detected by sensor 47, the supply of packaging material is also stopped.

    Der Antrieb des Zuschnittaggregats 33 durch den Servomotor 41 erfolgt jedoch in Abstimmung bzw. synchron mit dem Maschinentakt. Zu diesem Zweck ist ein Sensor dem Zuschnittaggregat 33 zugeordnet, nämlich ein Initiator 58. Dieser wirkt mit einer (metallischen) Markierung 59 des Zuschnittaggregats 33 zusammen. Die Markierung 59 ist an der Messerwalze 35 angebracht und steuert in Abstimmung mit dem Maschinentakt den Antrieb des Zuschnittaggregats 33.The drive of the cutting unit 33 by the servo motor 41 however, takes place in coordination or in synchronism with the machine cycle. For this purpose, a sensor is the cutting unit 33 assigned, namely an initiator 58. This acts with a (metallic) marking 59 of the cutting unit 33 together. The mark 59 is attached to the knife roller 35 and controls the drive of the cutting unit in coordination with the machine cycle 33rd

    Eine Besonderheit der Vorrichtung besteht darin, dass die Zigarettengruppen 23 ungleichförmig gefördert werden, nämlich mit schwellend ansteigender und entsprechend abfallender Fördergeschwindigkeit. Der Antrieb ist so gewählt, dass der Zigarettenförderer 25 während der Übernahme einer Zigarettengruppe 23 im Bereich des Zigarettenrevolvers 24 eine verminderte Geschwindigkeit aufweist. Gleichermaßen ist eine verminderte Geschwindigkeit des Zigarettenförderers 25 im Moment der Übernahme eines Zuschnitts 10 durch eine Zigarettengruppe 23 gegeben. Während der übrigen Phase der Förderung wird der Zigarettenförderer 25 mit entsprechend höherer Geschwindigkeit angetrieben. Vorzugsweise wird so vorgegangen, dass gleichzeitig eine Zigarettengruppe 23 im Bereich des Zigarettenmagazins 24 und ein Zuschnitt 10 von einer anderen Zigarettengruppe 23 erfaßt wird. Der Zigarettenförderer kann dabei beispielsweise nach Maßgabe der DE 1 288 970 angetrieben sein, also mit zyklisch wechselnder Geschwindigkeit. A special feature of the device is that the cigarette groups 23 are promoted non-uniformly, namely with increasing and correspondingly decreasing conveying speed. The drive is chosen so that the cigarette conveyor 25 during the takeover of a cigarette group 23 in Area of the cigarette revolver 24 a reduced speed having. Likewise is a reduced speed of the cigarette conveyor 25 at the time of the takeover a blank 10 given by a cigarette group 23. During the rest of the promotion, the cigarette conveyor 25 driven at a correspondingly higher speed. The procedure is preferably such that a cigarette group is used at the same time 23 in the area of the cigarette magazine 24 and a Blank 10 from another cigarette group 23 is detected. The cigarette conveyor can, for example, as required of DE 1 288 970 be driven, that is with a cyclically changing Speed.

    Die Bewegungscharakteristik des Zuschnittaggregats 33 ist an die Bewegungscharakteristik des Zigarettenförderers 25 angepaßt, nämlich ungleichförmig mit an- und abschwellendem Verlauf. Die Charakteristik der Förderbewegung ist so gewählt, dass während der Übernahme eines Zuschnitts 10 durch eine Zigarettengruppe 23 die Fördergeschwindigkeit des Zuschnitts 10 reduziert, im übrigen aber entsprechend erhöht ist. Diese Förderbewegung für die Materialbahn 29 bzw. den Zuschnitt 10 wird durch die Prägewalze 37 bewirkt, die als Exzenterwalze ausgebildet bzw. gelagert ist, nämlich mit außermittig liegender Drehachse 48. Die Anordnung ist so getroffen, dass die Prägewalze 37 während der Prägung, also während des Anbringens der Querprägelinie 19, 20, mit verminderter Geschwindigkeit gefördert wird und danach mit entsprechend höherer Geschwindigkeit.The movement characteristic of the cutting unit 33 is on adapted the movement characteristics of the cigarette conveyor 25, namely non-uniform with increasing and decreasing course. The characteristic of the funding movement is chosen so that during the takeover of a blank 10 by a cigarette group 23 the conveying speed of the blank 10 reduced, but is increased accordingly. This funding movement for the material web 29 or the blank 10 caused by the embossing roller 37, which is designed as an eccentric roller or is stored, namely with off-center Axis of rotation 48. The arrangement is such that the embossing roller 37 during the embossing, that is to say during the application of the Cross embossing line 19, 20, conveyed at reduced speed and then at a correspondingly higher speed.

    Der von der Materialbahn 29 abgetrennte Zuschnitt 10 wird von der Messerwalze 35 an drehende Saugscheiben 51 übergeben. Die Saugscheiben 51 sind längs des Umfangs mit Saugbohrungen versehen und erfassen den Zuschnitt an seitlichen Rändern. Die Zigarettengruppen 23 sind zwischen den Saugscheiben 51 hindurchförderbar, wobei der Zuschnitt im Bereich der Bodenwand 11 von der Zigarettengruppe 23 erfaßt und von den Saugscheiben 51 abgezogen wird.The blank 10 separated from the material web 29 is cut by passed the knife roller 35 to rotating suction disks 51. The Suction disks 51 are provided with suction bores along the circumference and capture the cut on the side edges. The Cigarette groups 23 can be conveyed between the suction disks 51, the cut in the area of the bottom wall 11 gripped by the cigarette group 23 and by the suction disks 51 is subtracted.

    Im Bereich des Mundstücks 30 sind weitere Hilfsorgane angeordnet, die die belastungsfreie Mitnahme des Zuschnitts 10 durch die Zigarettengruppe 23 unterstützen. Es handelt sich dabei um Saugwalzen 53, 54, die queraxial zur Förderrichtung der Zigarettengruppen 23 oberhalb und unterhalb der Bewegungsbahn derselben positioniert sind, und zwar als Eingangsorgane des Mundstücks 30. Die Zigarettengruppe 23 wird mit dem Zuschnitt 10 zwischen den oberen und unteren Saugwalzen 53, 54 hindurchgefördert.In the area of the mouthpiece 30, further auxiliary organs are arranged, which the load-free taking of the blank 10 through support the cigarette group 23. It is about Suction rolls 53, 54, which are transverse to the direction of conveyance of the cigarette groups 23 above and below the trajectory of the same are positioned, namely as the input organs of the mouthpiece 30. The cigarette group 23 is cut to size 10 conveyed between the upper and lower suction rollers 53, 54.

    Die besondere Antriebsform des Zigarettenförderers 25 kann auch in anderem Zusammenhang eingesetzt werden, also unabhängig von der Prägung der Innenumhüllung. The special drive form of the cigarette conveyor 25 can also are used in a different context, i.e. independently of the embossing of the inner casing.
