Description

Die Erfindung betrifft einen Bodenfaltungspacker zum Verpacken von Zi­garetten mit einem hohle, sternförmig angeordnete Faltdorne aufweisenden Um­hüllrevolver, der taktweise um jeweils eine Faltdornteilung weiterschaltbar ist, mit Einrichtungen zum Zuführen sowohl von Innen- als auch von Außenpapier sowie mit stationären und beweglichen Faltorganen zum Falten des Innenpapiers um einen mit einem Zigarettenblock gefüllten Faltdorn und des Außenpapiers um das um den Faltdorn gefaltete Innenpapier.The invention relates to a bottom-folding packer for packing cigarettes with a hollow, star-shaped folding mandrel having a revolving turret which can be incrementally incremented by one folding mandrel division, with devices for feeding both inner and outer paper and with stationary and movable folding members for folding the inner paper around a folding mandrel filled with a cigarette block and the outer paper around the inner paper folded around the folding mandrel.

Ein derartiger Bodenfaltungspacker zur Herstellung sogenannter Weich­packungen ist beispielsweise aus der DE-A-3 0 46 063 oder WO 80/00246 bekannt. Hierbei wird Innenpapier in Form von mit Aluminiumfolie beschichteter Folie eingesetzt, das in der umgefalteten Form trotz der Tatsache, daß auf einem derartigen Packer keine schargen Kanten gefaltet werden können, verbleibt, auch wenn das entsprechende Faltorgan zum entsprechenden Umfalten des Außen­papiers vom Innenpapier abhebt.Such a bottom folding packer for producing so-called soft packs is known, for example, from DE-A-3 0 46 063 or WO 80/00246. Here, inner paper is used in the form of foil coated with aluminum foil, which remains in the folded form despite the fact that no sharp edges can be folded on such a packer, even if the corresponding folding element lifts off the inner paper to fold the outer paper accordingly.

Mit Aluminiumfolie beschichtete Folie ist jedoch relative teuer, weshalb es wünschenswert wäre, metallisierte Folie verwenden zu können. Diese kehrt jedoch, wenn sie nach dem Falten losgelassen wird, im wesentlichen in ihre ursprüngliche Form zurück, d.h. sie springt auf. Ein Verarbeiten von metalli­sierter Folie auf einem Bodenfaltungspacker ist daher nicht möglich.However, foil coated with aluminum foil is relatively expensive, which is why it would be desirable to be able to use metallized foil. However, when released after being folded, it essentially returns to its original shape, i.e. she jumps up. It is therefore not possible to process metallized film on a bottom folding packer.

Aufgabe der Erfindung ist es daher, einen Bodenfaltungspacker der ein­ gangs genannten Art zu schaffen, mit dem sich metallisierte Folie als Innen­papier verarbeiten läßt.The object of the invention is therefore a bottom folding packer to create the type mentioned above, with which metallized film can be processed as inner paper.

Diese Aufgabe wird dadurch gelöst, daß sich über den von den Faltdornen durchlaufenen Bereich, in dem das Einfalten des Innenpapierbodens bis zum kompletten Schließen des Außenpapierbodens stattfindet, eine die Faltdorne kopfseitig beaufschlagende Saugstrecke vorgesehen ist und die Faltdorne in ihrer bezüglich der Revolverdrehrichtung nachlaufenden Radialwandung mit Lö­chern versehen sind.This object is achieved in that over the area traversed by the folding mandrels, in which the folding of the inner paper bottom takes place until the outer paper bottom is completely closed, a suction path acting on the folding mandrels on the head side is provided and the folding mandrels with holes in their radial wall trailing with respect to the direction of rotation of the turret are provided.

Hierbei ist es zweckmäßig, wenn die Saugstrecke ein an eine Unterdruck­quelle angeschlossener, sich über einen Kreisringabschnitt erstreckender Kanal ist, der faltdornseitig mit Saugöffnungen versehen ist, deren Abstand in Um­fangsrichtung geringer als die Breite eines Faltdorns ist, und wenn zwischen den Faltdornen Abdeckbleche für die sich zwischen den Faltdornen befindende Saugstrecke angeordnet sind.It is expedient here if the suction path is a channel connected to a vacuum source and extending over a circular ring section, which is provided with suction openings on the folding mandrel side, the spacing of which in the circumferential direction is less than the width of a folding mandrel, and if cover plates for the are located between the folding mandrels suction path located between the folding mandrels are arranged.

Die Erfindung wird nachstehend anhand des in den beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.

  • Fig. 1 zeigt schematisiert und ausschnittweise in Frontansicht einen Revolver eines Seitenfaltungspackers im wesentlichen in dem Bereich, in dem Innen- und Außenpapier gefaltet werden.
  • Fig. 2a und 2b zeigen einen Faltdorn des Revolvers von Fig. 1 im Schnitt und in Frontansicht.
  • Fig. 3a bis 3f zeigen verschiedene Stadien beim Falten von Innen- und Außenpapier um einen Faltdorn.
The invention is explained below with reference to the embodiment shown in the accompanying figures.
  • Fig. 1 shows schematically and partially a front view of a revolver of a side-folding packer essentially in the area in which the inner and outer paper are folded.
  • 2a and 2b show a folding mandrel of the turret of Fig. 1 in section and in front view.
  • 3a to 3f show different stages in the folding of inner and outer paper around a folding mandrel.

Der ausschnittweise dargestellte Bodenfaltungspacker besitzt einen Um­hüllrevolver 1, dem Zigaretten 2 in Form eines Zigarettenblocks etwa über ei­nen (nicht dargestellten) Blockrevolver, dessen in Übergabeposition befindli­che Zelle axial fluchtend zu einem mit einem kopfseitigen Mundstück 3 verse­henen, hohlen Faltdorn 4 des Umhüllrevolvers 1 angeordnet ist, mittels eines (nicht dargestellten) Stößels zugeführt werden. Benachbart zum Umhüllrevolver 1 befinden sich eine (nicht dargestellte) Einrichtung zum Zuführen von Innen­papier 5 und eine Einrichtung 6 zum Zuführen von Außenpapier 7. Mit Hilfe von nur teilweise dargestellten stationären und beweglichen Faltorganen 8, 9, 10, 11 wird zunächst das Innenpapier 5 und dann das Außenpapier 7 um den Faltdorn 4 gefaltet, so sich eine bodenseitig geschlossene Packung ergibt, die zusammen mit dem im Faltdorn 4 befindlichen Zigarettenblock auf einen nicht darge­stellten Kopfschließrevolver überschoben wird, wo die Packung kopfseitig ge­schlossen wird. Der Antrieb ist ein Schrittschaltantrieb, durch den die Re­ volver um jeweils eine Zellenteilung weiterschaltbar sind, wobei sich der Um­hüllrevolver 1 in Richtung des Pfeils 12 dreht. Da dies an sich beispiels­weise aus den eingangs genannten Schriften bekannt ist, wird hierauf nicht näher eingegangen.The bottom folding packer shown in sections has an enveloping turret 1, the cigarette 2 in the form of a block of cigarettes, for example, via a turret (not shown), the cell in the transfer position of which is axially aligned with a hollow folding pin 4 of the enveloping turret 1 provided with a mouthpiece 3 on the head side, by means of a plunger (not shown). Adjacent to the enveloping turret 1 are a device (not shown) for feeding inner paper 5 and a device 6 for feeding outer paper 7. With the help of only partially illustrated stationary and movable folding members 8, 9, 10, 11, the inner paper 5 and then the outer paper 7 is folded around the folding mandrel 4, so that a bottom-closed package results which, together with the cigarette block located in the folding mandrel 4, is pushed onto a head-closing revolver, not shown, where the package is closed on the head side. The drive is a stepper drive through which the Re volver can be switched by one cell division, the enveloping revolver 1 rotates in the direction of arrow 12. Since this is known per se, for example, from the writings mentioned at the outset, it is not dealt with in more detail here.

Das zugeführte Innenpapier 5, ein rechteckiger Abschnitt einer metalli­sierten Folie, wird zunächst von einem kurvenbetätigten, auf dem Umhüllrevol­ver 1 gelagerten Faltarm 8 gegen die in Drehrichtung 12 des Umhüllrevolvers 1 vorlaufende Seitenwand des hohlen Faltdorns 4 gedrückt. Durch stationäre (nicht dargestellte) Faltorgane wird das Innenpapier entgegen der Drehrichtung 12 in Anlage an die oder- und unterseitige Wandung des Faltdorns 4 gebracht sowie anschließend durch entsprechende Falthebel (nicht dargestellt) auf die zur Drehrichtung 12 nachlaufende Seitenwandung des Faltdorns 4 umgefaltet. In dieser Stellung wird das Innenpapier 5 dann durch einen kurvenbetätigten, auf dem Umhüllrevolver 1 gelagerten Faltarm 9 gehalten, vgl. insbesondere Fig. 3b. Zur Bildung des Innenpapierbodens werden zunächst mittels eines nicht darge­stellten Faltorgans die bezüglich der Drehrichtung 12 nachlaufenden überste­henden Innenpapierabschnitte 13 in Drehrichtung 12 umgefaltet, wonach der verbleibende gegenüber dem Faltdorn 4 überstehende Abschnitt 14 durch Auflau­fen auf ein stationäres Faltorgan (nicht dargestellt) entgegen der Drehrich­tung 12 auf die Abschnitte 13 umgefaltet wird. Ober- und unterseitige Zipfel 15 bleiben hierbei zunächst bestehen (vgl. Fig. 3c).The supplied inner paper 5, a rectangular section of a metallized film, is first pressed by a cam-operated folding arm 8, which is mounted on the enveloping turret 1, against the side wall of the hollow folding mandrel 4 which runs in the direction of rotation 12 of the enveloping revolver 1. By means of stationary (not shown) folding members, the inner paper is brought into contact against the direction of rotation 12 against the or- and underside wall of the folding mandrel 4 and then folded over by appropriate folding levers (not shown) onto the side wall of the folding mandrel 4 trailing in the direction of rotation 12. The inner paper 5 is then held in this position by a cam-operated folding arm 9 mounted on the enveloping turret 1, cf. in particular Fig. 3b. To form the inner paper base, the protruding inner paper sections 13 trailing with respect to the direction of rotation 12 are first folded in the direction of rotation 12 by means of a folding member (not shown), after which the remaining section 14 protruding from the folding mandrel 4 by running onto a stationary folding member (not shown) against the direction of rotation 12 the sections 13 is folded over. The top and bottom tips 15 initially remain (see FIG. 3c).

Danach wird das Außenpapier 7 zugeführt, indem der Faltarm 8 vom Innen­papier 5 entfernt und das Außenpapier 7 nach oben und unten gegenüber dem Faltdorn 4 überstehend zwischen das Innenpapier 5 und den Faltarm 8 eingeführt wird. Der Faltarm 8 legt sich außenseitig an das Außenpapier 7 an und der Faltdorn läuft zwischen zwei stationären Faltorganen 10, 11 hindurch, die das Außenpapier 7 um das Innenpapier 5 herum entgegen der Drehrichtung 12 umfal­ten. Mittels zweier nicht dargestellter Falthebel werden die nach hinten überstehenden Abschnitte des Außenpapiers 7 in radialer Richtung auf das In­nenpapier 5 umgefaltet, während der Falthebel 8 das Außenpapier 7 weiterhin festhält. Dann erfolgt das Schließen des Außenpapierbodens zunächst durch zwei radial bewegliche Faltdaumen (nicht dargestellt), durch die außerdem die Zip­fel 15 des Innenpapiers 5 einwärts gefaltet werden, während beide Falthebel 8, 9 das Außenpapier 7 gegen den Faltdorn 4 gedrückt halten (vgl. Fig. 3d, 3e). Anschließend erfolgt das Falten der noch verbleibenden Seitenteile des Außen­papierbodens übereinander durch zwei (nicht dargestellte) Faltorgane, von de­nen eines stationär angeordnet ist (vgl. Fig. 3f und 1).The outer paper 7 is then fed in by removing the folding arm 8 from the inner paper 5 and inserting the outer paper 7 upwards and downwards over the folding mandrel 4, projecting between the inner paper 5 and the folding arm 8. The folding arm 8 rests on the outside against the outer paper 7 and the folding mandrel runs between two stationary folding members 10, 11, which fold the outer paper 7 around the inner paper 5 against the direction of rotation 12. By means of two folding levers, not shown, the portions of the outer paper 7 projecting to the rear are folded over onto the inner paper 5 in the radial direction, while the folding lever 8 continues to hold the outer paper 7. Then the outer paper base is first closed by two radially movable folding thumbs (not shown), through which the tips 15 of the inner paper 5 are also folded inwards, while both folding levers 8, 9 hold the outer paper 7 pressed against the folding mandrel 4 (cf. 3d, 3e). The remaining side parts of the outer paper base are then folded one above the other by two (not shown) folding members, one of which is arranged in a stationary manner (see FIGS. 3f and 1).

Damit das um den Faltdorn 4 gefaltete Innenpapier 5 nicht aufspringen kann, ist in dem von den Faltdornen 4 durchlaufenen Bereich, in dem das Ein­falten des Innenpapierbodens bis zum kompletten Schließen des Außenpapierbo­dens stattfindet (vgl. Fig. 1), eine die Faltdorne 4 kopfseitig, d.h. vom Mundstück 3 her beaufschlagende Saugstrecke vorgesehen, die aus einem an eine Unterdruckquelle über einen Anschluß 16 angeschlossenen, sich über einen Kreisringabschnitt erstreckenden Kanal 17 besteht, der faltdornseitig mit Saugöffnungen 18 versehen ist, deren Abstand in Umfangsrichtung geringer als die Breite eines Faltdorns 4 ist.So that the inner paper 5 folded around the folding mandrel 4 cannot open, in the area through which the folding mandrels 4 pass, in which the inner paper bottom is folded in until the outer paper bottom is completely closed (see FIG. 1), one of the folding mandrels 4 is on the head side, ie from the mouthpiece 3 acting suction section is provided, which consists of a connected to a vacuum source via a connection 16, extending over a circular ring section, which is provided on the folding mandrel side with suction openings 18, the circumferential distance of which is smaller than the width of a folding mandrel 4.

Außerdem sind die Faltdorne 4 in ihrer bezüglich der Revolverdrehrich­tung 12 nachlaufenden Seitenwandung mit Löchern oder Perforation 19 verse­hen.In addition, the folding mandrels 4 are provided with holes or perforations 19 in their side wall trailing with respect to the turret rotation direction 12.

Hierdurch wird erreicht, daß das Innere der Faltdorne 4 bei Erreichen der Position, in der der Innenpapierboden gebildet werden soll (Fig. 1), über die Saugöffnungen 18 mit Unterdruck beaufschlagt wird, so daß die Lücken zwi­schen den Zigaretten 2 wie Saugluftbohrungen wirken und die Bodenabschnitte 13, 14 ansaugen sowie diese in der umgefalteten Position halten. Entsprechend wirken die seitlichen Löcher 19, die die Abschnitte 5ʹ und 5ʺ des Innenpapiers in Anlage an den Faltdorn 4 halten, wenn der Hebel 9 hiervon abhebt, damit das Außenpapier 7 auch in diesem Bereich auf das Innenpapier 5 gefaltet werden kann. Die seitlichen Löcher 19 sind zweckmäßigerweise in zwei übereinander liegenden Reihen derart angeordnet, daß eine Reihe den Abschnitt 5ʹ und die andere den Abschnitt 5ʺ festhält. Auf diese Weise kann als Innenpapier 5 eine metallisierte Folie verwendet werden, ohne daß zu befürchten ist, daß diese während des Faltvorgangs wieder aufspringt.This ensures that the inside of the folding mandrels 4 when the position in which the inner paper base is to be formed (Fig. 1) is applied via the suction openings 18 with vacuum, so that the gaps between the cigarettes 2 act like suction air holes and the Aspirate bottom sections 13, 14 and hold them in the folded position. The lateral holes 19, which hold the sections 5ʹ and 5ʺ of the inner paper in contact with the folding mandrel 4, act correspondingly when the lever 9 lifts therefrom, so that the outer paper 7 can also be folded onto the inner paper 5 in this area. The side holes 19 are expediently arranged in two rows one above the other such that one row holds the section 5ʹ and the other the section 5 den. In this way, a metallized film can be used as the inner paper 5 without fear that it will open again during the folding process.

Zur Verminderung der benötigten Saugluftleistung können zwischen den Faltdornen 4 Abdeckbleche für die sich zwischen den Faltdornen 4 befindliche Saugstrecke angeordnet sein, jedoch können diese eventuell die Zugänglichkeit beeinträchtigen.To reduce the required suction air power, 4 cover plates for the suction section located between the folding mandrels 4 can be arranged between the folding mandrels, but these can possibly impair the accessibility.

Beispielsweise ist der Kanal 17 an eine Pumpe mit einer Leistung von 180 m³/h angeschlossen, so daß sich ein maximaler Unterdruck von 225 mbar ergibt.For example, the channel 17 is connected to a pump with an output of 180 m³ / h, so that there is a maximum negative pressure of 225 mbar.
