Der Erfindung liegt deshalb die Aufgabe zu Grunde, Maßnahmen für eine rationelle, insbesondere kontinuierliche Fertigung von Hartpackungen im Allgemeinen und Klappschachteln bzw. Schieber- und Hülsepackungen im Besonderen vorzuschlagen.The invention is therefore based on the object to propose measures for a rational, in particular continuous production of hard packs in general and folding boxes or slide and sleeve packs in particular.

Zur Lösung dieser Aufgabe besteht das erfindungsgemäße Verfahren in folgenden Merkmalen:

  • a) die Außenumhüllung wird mit einer im Querschnitt geschlossenen, rechteckigen und an mindestens einem Ende offenen Hülse als äußere Packungseinheit vorgefertigt,
  • b) der Packungsinhalt wird unter Verwendung eines dünnwandigen Hohlkörpers - Faltdorn - gesondert vorbearbeitet, wobei auf der Außenseite des Faltdorns die Innenumhüllung angebracht und gefaltet wird sowie mindestens ein zusätzliches Packungsteil, insbesondere Kragen oder Schieber (slide),
  • c) die Zigarettengruppe wird aus dem Faltdorn ausgeschoben unter Mitnahme der im Bereich einer Bodenwand geschlossenen bzw. gefalteten Innenumhüllung und des außen aufliegenden zusätzlichen Packungsteils unter Bildung einer inneren Packungseinheit,
  • d) die innere Packungseinheit wird unmittelbar im Anschluss an den Faltdorn in die offene Seite der als Hülse benachbart zum Faltdorn bereitgehaltenen Außenumhüllung eingeschoben,
  • e) die Packung wird sodann fertiggefaltet, wobei zuerst Faltlappen einer Stirnwand der Innenumhüllung und sodann Faltlappen des Schiebers oder eines Deckels gefaltet werden.
To solve this problem, the method according to the invention consists of the following features:
  • a) the outer sheath is prefabricated with a cross-sectionally closed, rectangular sleeve open at at least one end as outer packing unit,
  • b) the contents of the package are preprocessed separately using a thin-walled hollow body-folding mandrel-on the outside of the folding mandrel, the inner casing is attached and folded, and at least one additional packing part, in particular collar or slide,
  • c) the group of cigarettes is ejected from the folding mandrel with the entrainment of the inner sheath closed or folded in the region of a bottom wall and of the outer additional pack part, forming an inner packing unit,
  • d) the inner packing unit is inserted immediately after the folding mandrel into the open side of the outer casing held as a sleeve adjacent to the folding mandrel,
  • e) the package is then folded to completion, first folding flaps of an end wall of the inner wrapper and then folding flaps of the slider or a lid are folded.

Der Erfindungsgedanke besteht demnach darin, zwei Packungseinheiten, nämlich die Außenumhüllung einerseits und den Packungsinhalt - Zigarettenblock - mit einem zusätzlichen Packungsteil (Kragen oder Schieber) andererseits gesondert während des (kontinuierlichen) Transports entlang paralleler, synchron gesteuerter Bewegungsbahnen vorzubereiten bzw. vorzufalten und dann diese Packungseinheiten durch quer zur Förderrichtung verlaufende Bewegung miteinander zu vereinen. Danach werden erfindungsgemäß abschließende Faltschritte durchgeführt zur Komplettierung der Packung.The concept of the invention therefore consists of preparing or prefolding two packing units, namely the outer casing on the one hand and the pack contents - cigarette block - with an additional packing part (collar or slider) separately during the (continuous) transport along parallel, synchronously controlled movement paths and then these packing units to unite by transverse to the conveying direction movement. Thereafter, according to the invention, final folding steps are carried out to complete the package.

Die innere Packungseinheit wird auf einem Faltrevolver gefertigt, der mit Falthohlkörpem, nämlich Faltdomen, ausgestattet ist. Auf der Außenseite wird die Innenumhüllung vorbereitet und Kragen bzw. Schieber positioniert. Innen befindet sich die Zigarettengruppe. Die andere, äußere Packungseinheit wird in mit den Faltdomen synchron und gleichgerichtet umlaufenden Taschen bzw. entsprechenden Halterungen vorbereitet.The inner packing unit is manufactured on a folding turret, which is equipped with Falthohlkörpem, namely Faltdomen. On the outside of the inner wrapper is prepared and positioned collar or slider. Inside is the cigarette group. The other, outer packing unit is prepared in synchronous with the folding domes and rectified circumferential pockets or corresponding brackets.

Eine Besonderheit besteht darin, dass in einem ersten Bewegungstäkt die innere Packungseinheit - Zigarettenblock mit Kragen oder Schieber - nur mit einem Teilbereich in den Schachtelteil bzw. in die Hülse eingeschoben und danach - nämlich nach dem Lösen vom Faltdorn - die Faltung des Innenzuschnitts, des Schiebers und - bei Klappschachteln - Faltungen an der Außenumhüllung komplettiert werden, bevor der Packungsinhalt vollständig in den Schachtelteil bzw. in die Hülse eingeschoben wird.A special feature is that in a first Bewegungsstäkt the inner packing unit - cigarette block with collar or slider - inserted only with a portion in the box part or in the sleeve and then - namely after release from the folding mandrel - the folding of the inner blank, the slider and - in folding boxes - Folds are completed on the outer sheath before the contents of the package is completely inserted into the box part or in the sleeve.

Eine weitere Besonderheit ist die Zuführung des Kragens bzw. des Schiebers zum Faltdorn und die Faltung dieses Packungsteils.Another special feature is the supply of the collar or the slider to the folding mandrel and the folding of this pack part.

Die in den Zeichnungen dargestellten Ausführungsbeispiele befassen sich mit der Fertigung von Hartpackungen für Zigaretten. Mindestens eine Außenumhüllung besteht aus dünnem Karton.The embodiments illustrated in the drawings are concerned with the production of hard packs for cigarettes. At least one outer wrapper is made of thin cardboard.

Fig. 1 zeigt eine Zigarettenpackung des Typs Schieber und Hülse (shell and süde). Bei diesem Packungstyp ist ein Zigarettenblock 10, bestehend aus einer in einen Innenzuschnitt 11 eingehüllten Zigarettengruppe 12, in einem Innenteil der Packung angeordnet, nämlich in einem Schieber 13. Dieser ist im Querschnitt U-förmig ausgebildet, besteht aus Schieberwand 14, Seitenstegen 15, einer Bodenlasche 16 und einer Stimiasche 17. Die Bodenlasche 16 und Stirnlasche 17 weisen jeweils eine Fortsetzung auf, nämlich eine Stecklasche 18 bzw. 19. Der Schieber 13 besteht ebenfalls aus Karton.Fig. 1 shows a cigarette pack of the type slide and sleeve (shell and south). In this type of package, a cigarette block 10, consisting of a wrapped into an inner blank 11 cigarette group 12, arranged in an inner part of the pack, namely in a slide 13. This is U-shaped in cross-section, consists of slide wall 14, side bars 15, a Bottom flap 16 and a Stimiasche 17. The bottom flap 16 and end flap 17 each have a continuation, namely a plug-in tab 18 and 19. The slider 13 is also made of cardboard.

Eine aus Zigarettenblock 10 und Schieber 13 gebildete (innere) Packungseinheit ist in einer Außenumhüllung angeordnet, nämlich in einer Hülse 20. Es handelt sich dabei um eine im Querschnitt geschlossene, an beiden Enden offene äußere Packungseinheit mit Vorderwand 21, Rückwand 22 sowie Seitenwänden 23. Bei der kontinuierlichen Fertigung werden die beiden Packungseinheiten in zwei parallelen Bewegungsbahnen gefördert, gefaltet bzw. komplettiert und sodann zur Bildung der Packung mittels Querverschiebung vereinigt.An (inner) packing unit formed from cigarette block 10 and slide 13 is arranged in an outer casing, namely in a sleeve 20. This is an outer packing unit with front wall 21, rear wall 22 and side walls 23 which is closed in cross section and open at both ends. In continuous production, the two packing units are conveyed in two parallel trajectories, folded or completed and then combined to form the package by means of transverse displacement.

Ein erster Faltrevolver, nämlich Dornrevolver 24, befasst sich mit der Vorbereitung der aus Zigarettenblock 10 und Schieber 13 bestehenden Packungseinheit. Der Dornrevolver 24 weist eine Vielzahl von längs des Umfangs verteilt angeordneten Faltdomen 25, also dünnwandige Hohlkörper, die an beiden Enden offen sind. Im Inneren des im Querschnitt rechteckigen Faltdorns 25 findet jeweils eine Zigarettengruppe 12 Aufnahme. Die Zigarettengruppen 12 werden durch einen Endlosförderer, nämlich durch eine Taschenkette 26 dem Dornrevolver 24 zugeführt. Im Bereich eines Umfangsabschnitts läuft die Taschenkette 26 in axialer Ausrichtung mit den Faltdomen 25. Die Zigarettengruppen 12 werden in diesem Bereich aus den Taschen der Taschenkette 26 in achsparalleler Richtung aus- und in einen zugeordneten Faltdorn 25 eingeschoben (US 4 750 607).A first folding turret, namely mandrel turret 24, deals with the preparation of the packaging unit consisting of cigarette block 10 and slide 13. The mandrel turret 24 has a multiplicity of folding mandrels 25 distributed along the circumference, ie thin-walled hollow bodies which are open at both ends. Inside the folding mandrel 25, which is rectangular in cross-section, there is a respective cigarette group 12. The groups of cigarettes 12 are fed to the mandrel turret 24 by an endless conveyor, namely by a pocket chain 26. In the region of a peripheral portion, the pocket chain 26 runs in axial alignment with the folding domes 25. The cigarette groups 12 are in this area from the pockets of the bag chain 26 in the axis-parallel direction off and inserted into an associated folding mandrel 25 (US 4,750,607).

Bei fortgesetzter Drehbewegung des Dornrevolvers 24 gelangen die Faltdorne 25 mit jeweils einer Zigarettengruppe 12 in den Bereich einer Zuschnittstation 27. Im Bereich derselben wird ein Innenzuschnitt 11 bereitgehalten und an den Faltdorn 25 angelegt. Der Innenzuschnitt 11 ist dabei so positioniert, dass an einer in Drehrichtung rückwärtigen Seitenwand 28 des Faltdorns 25 Faltlappen überstehen, von denen ein radial außen liegender, innerer Faltlappen durch ein Faltorgan 29 und danach ein außen liegender Faltlappen durch einen Falthebel 30 gegen die Seitenwand 28 gefaltet wird. Der Falthebel 30 ist winkelförmig ausgebildet mit einem etwa radial gerichteten Faltschenkel 31. Dieser fixiert die beiden Faltlappen des Innenzuschnitts 11 an der Seitenwand 28 des Faltdorns 25.With continued rotational movement of the mandrel turret 24, the folding mandrels 25, each with a cigarette group 12, reach the area of a blanking station 27. In the area thereof, an inner blank 11 is held ready and applied to the folding mandrel 25. The inner blank 11 is positioned so that 25 overlap at a rear side in the direction of rotation of the folding mandrel 25 folding flaps, of which a radially outer, inner folding flaps folded by a folding member 29 and then an outboard folding tab by a folding lever 30 against the side wall 28 becomes. The folding lever 30 is angularly formed with an approximately radially directed folding leg 31. This folds the two folding tabs of the inner blank 11 on the side wall 28 of the folding mandrel 25th

Bei fortgesetzter Drehung des Faltrevolvers bzw. Dornrevolvers 24 wird eine am freien Ende des Faltdorns 25 durch überstehende Faltlappen gebildete Bodenfaltung 32 des Innenzuschnitts 11 hergestellt, und zwar durch herkömmliche, bekannte Faltorgane.With continued rotation of the folding turret or mandrel 24, a bottom fold 32 of the inner blank 11 formed at the free end of the folding mandrel 25 by projecting folding tabs is produced, by conventional, known folding members.

In besonderer Weise ist eine in Bewegungsrichtung des Dornrevolvers 24 folgende Schieberstation 33 ausgebildet. Im Bereich derselben wird ein Zuschnitt zur Bildung des Schiebers 13 zugeführt und an die Außenseite des Faltdorns 25 bzw. des Innenzuschnitts 11 angelegt zur Bildung der Packungseinheit aus Zigarettenblock 10 und Schieber 13. Die Zuschnitte für den Schieber 13 werden einem Zuschnittmagazin 34 entnommen und ungefaltet aus einer horizontalen Ebene in eine vertikale Ebene umgelenkt, und zwar durch eine Umlenkwalze 35. Die Zuschnitte werden sodann in der Vertikalebene abwärtsbewegt. Die Schieberstation 33 ist oberhalb des in einer vertikalen Ebene rotierenden Dornrevolvers 24 angebracht. In Radialrichtung werden die Zuschnitte des Schiebers 13 einem zugeordneten Faltdorn 25 zugeführt während der fortgesetzten Drehbewegung (Fig. 4). Zur Umlenkung des Zuschnitts sind der Umlenkwalze 35 mehrere am Außenumfang angeordnete Gegenwalzen 36 zugeordnet.In a special way, a following in the direction of movement of the mandrel turret 24 slide station 33 is formed. In the area of the same, a blank for forming the slider 13 is supplied and applied to the outside of the folding mandrel 25 and the inner blank 11 to form the packing unit of cigarette block 10 and slide 13. The blanks for the slide 13 are taken from a blank magazine 34 and unfolded a horizontal plane deflected into a vertical plane, by a guide roller 35. The blanks are then moved down in the vertical plane. The slider station 33 is mounted above the mandrel turret 24 rotating in a vertical plane. In the radial direction, the blanks of the slider 13 are fed to an associated folding mandrel 25 during the continued rotational movement (Figure 4). For deflecting the blank, the guide roller 35 is assigned a plurality of counter-rollers 36 arranged on the outer circumference.

Der Schieber 13 wird so an den Dornrevolver 24 übergeben, dass ein Randbereich an einer in Drehrichtung vorderen Seitenwand 37 des Faltdorns 25 bzw. des Innenzuschnitts 11 anliegt. Der Zuschnitt des Schiebers 13 wird quer zur Längserstreckung zugefördert. Ein in Förderrichtung vomliegender Seitensteg 15 erhält Anlage an der Seitenwand 37. Durch entsprechende Ausbildung einer Förderwalze 38 wird der Zuschnitt des Schiebers 13 sodann freigegeben und kann von dem Dornrevolver 25 mitgenommen werden. Der Schieber 13 wird dabei an dem betreffenden Faltdorn 25, nämlich an der vorderen Seitenwand 37 fixiert, und zwar durch ein Andrückorgan, nämlich eine Andrückwalze 39, die an einem Hebel 40 angebracht ist und aufgrund entsprechend gesteuerter Bewegung den Zuschnitt des Schiebers 13 am Faltdorn 25 bzw. Innenzuschnitt 11 gehaften.The slider 13 is transferred to the mandrel turret 24 so that an edge region abuts against a front side wall 37 of the folding mandrel 25 or the inner blank 11 that is in the direction of rotation. The blank of the slider 13 is conveyed transversely to the longitudinal extent. A in the conveying direction vomliegender side bar 15 receives contact with the side wall 37. By appropriate design of a feed roller 38 of the blank of the slider 13 then released and can be taken from the mandrel turret 25. The slider 13 is thereby fixed to the respective folding mandrel 25, namely on the front side wall 37, by a Andrückorgan, namely a pressure roller 39 which is attached to a lever 40 and due to appropriately controlled movement the blank of the slider 13 on the folding mandrel 25th or inner blank 11 stick.

Bei Weiterbewegung des Dornrevolvers 24 wird der Schieber 13 um den Faltdorn 25 herumgefaltet durch bekannte Faltorgane. Ein in Förderrichtung rückseitig überstehender Schenkel wird durch ein Faltrad 41 gegen die rückwärtige Seitenwand 28 umgefaltet (Fig. 4, links). Der Falthebel 36 wird bei dieser Gelegenheit kurzzeitig betätigt, derart, dass der Faltschenkel 31 abgehoben und der Seitensteg 15 gefaltet werden kann. Dieser wird dann durch den Falthebel 30 mit fixiert.Upon further movement of the mandrel turret 24, the slider 13 is folded around the folding mandrel 25 by known Faltorgane. A leg protruding in the direction of conveyance is folded over by a folding wheel 41 against the rear side wall 28 (FIG. 4, left). The folding lever 36 is briefly actuated on this occasion, such that the folding leg 31 lifted off and the side web 15 can be folded. This is then fixed by the folding lever 30 with.

Im weiteren Verlauf der Drehbewegung des Dornrevolvers 24 wird die Bodenlasche 16 des Schiebers 13 einschließlich der zugeordneten Stecklasche 18 gefaltet. Damit ist die auf dem Faltdorn 25 gebildete innere Packungseinheit fertiggestellt.In the further course of the rotational movement of the mandrel turret 24, the bottom flap 16 of the slider 13, including the associated insertion tab 18, is folded. Thus, the formed on the folding mandrel 25 inner packing unit is completed.

Separat, jedoch in abgestimmter und synchronisierter Weise wird die andere Packungseinheit vorbereitet. Es handelt sich dabei um die Hülse 20. Diese wird in einer zum Dornrevolver 24 versetzten, parallelen, aufrechten Ebene vorbereitet. Zu diesem Zweck werden fertige, flach zusammengelegte Hülsen 20 einem Hülsenmagazin 42 entnommen und durch einen Hülsenrevolver 43 einem Zwischenrevolver 44 zugeführt. Der Hülsenrevolver 43 weist eine Mehrzahl von längs des Umfangs angeordneten ebenen Anlageflächen 45 mit etwa radialgerichteter Querfläche auf. An den Anlageflächen 45 werden die Hülsen 20 jeweils mit einer großflächigen Wandung gehalten, und zwar durch Saugbohrungen (nicht gezeigt).Separately, but in a coordinated and synchronized manner, the other packing unit is prepared. It is the sleeve 20. This is prepared in a mandrel turret 24 offset, parallel, upright level. For this purpose, finished, flat-folded sleeves 20 are removed from a sleeve magazine 42 and fed through a sleeve turret 43 to an intermediate turret 44. The sleeve turret 43 has a plurality of planar contact surfaces 45, which are arranged along the circumference, with an approximately radially directed transverse surface. At the contact surfaces 45, the sleeves 20 are each held with a large wall, through suction holes (not shown).

Der Zwischenrevolver 44 weist Taschen 46 als Aufnahmen für die Hülsen 20 auf. Bei der Übergabe an den Zwischenrevolver 44 werden die Hülsen 20 in die dreidimensionale Form aufgerichtet. Der Ablauf ergibt sich aus Fig. 5. Die Taschen 46 weisen bewegliche, nämlich schwenkbare seitliche Taschenwände 47, 48 auf. Bei der Zuführung der leeren Taschen 46 zur Übernahme einer Hülse 20 befinden sich die Taschenwände 47, 48 in einer offenen, gespreizten Stellung (Fig. 5, unten). Die Relativbewegung zwischen dem Hülsenrevolver 43 und dem Zwischenrevolver 44 ist so gesteuert bzw. so gewählt, dass die Hülse 20 mit einer in Transportrichtung vomliegenden Faltkante 49 gegen die in Drehrichtung vom liegende Taschenwand 47 einer Tasche 46 gefördert wird. Eine diagonal an der Rückseite der Hülse 20 gegenüberliegende Faltkante 50 wird durch die andere, nachfolgende Taschenwand 48 erfasst. Durch Zusammenbewegen der Taschenwände 47, 48 wird die Hülse 20 aufgerichtet.The intermediate turret 44 has pockets 46 as receptacles for the sleeves 20. When transferring to the intermediate turret 44, the sleeves 20 are erected in the three-dimensional shape. The sequence results from FIG. 5. The pockets 46 have movable, namely pivotable, lateral pocket walls 47, 48. When feeding the empty pockets 46 to take over a sleeve 20, the pocket walls 47, 48 are in an open, spread position (FIG. 5, bottom). The relative movement between the sleeve turret 43 and the intermediate turret 44 is controlled or chosen so that the sleeve 20 is conveyed with a folding edge 49 lying in the transporting direction against the pocket wall 47 of a pocket 46 lying in the direction of rotation of the lying pocket wall. A folding edge 50 lying diagonally opposite the rear side of the sleeve 20 is grasped by the other, following pocket wall 48. By moving together the pocket walls 47, 48, the sleeve 20 is erected.

Die Taschen 46 weisen einen leicht gewölbten Boden 51 auf, an dem die Hülse 20 mit Vorderwand 21 oder Rückwand 22 anliegt. Des Weiteren ist ein Endhalter 52 vorgesehen, der die Hülse 20 in der Tasche 46 in Axialrichtung ausrichtet.The pockets 46 have a slightly curved bottom 51 on which the sleeve 20 rests with front wall 21 or rear wall 22. Furthermore, an end holder 52 is provided, which aligns the sleeve 20 in the pocket 46 in the axial direction.

Der Zwischenrevolver 24 transportiert die Hülsen 20 zu einem weiteren Revolver, nämlich einem Taschenrevolver 53. Dieser bildet das Gegenstück zum Dornrevolver 24, ist gleichachsig mit diesem gelagert und wird kontinuierlich drehend und synchron mit dem Dornrevolver 24 angetrieben. Insbesondere sind Dornrevolver 24 und Taschenrevolver 53 als Revolvereinheit ausgebildet mit zwei Teilrevolvern, analog zu US 5 979 140.The intermediate turret 24 transports the sleeves 20 to another revolver, namely a pocket turret 53. This forms the counterpart to the mandrel turret 24, is coaxially mounted therewith and is continuously driven in rotation and synchronously with the mandrel turret 24. In particular mandrel turret 24 and pocket turret 53 are designed as a turret unit with two partial revolvers, analogous to US Pat. No. 5,979,140.

Der Taschenrevolver 53 ist längs des Umfangs mit Aufnahmen für die Hülse 20 versehen, nämlich mit Hülsentaschen 54. Beide Halterungen, nämlich Faltdorne 25 einerseits und Hülsentaschen 54 andererseits werden entlang endloser, nämlich kreisförmiger Bewegungsbahnen gefördert, wobei einem Faltdorn 25 jeweils eine zugeordnete Hülsentasche 54 in exakter Ausrichtung mit Abstand gegenüberliegt. Während der Drehung der beiden Revolver 24 und 53 werden, soweit zutreffend, Faltungen durchgeführt bzw. Verschiebebewegungen. Die Übergabe der Hülsen vom Zwischenrevolver 24 erfolgt in der Weise, dass sich die Hülsentaschen 54 in einer in achsparalleler Richtung zurückgezogenen Stellung befinden. Die Hülsen 20 werden nun in einem Bereich zwischen den Hülsentaschen 54 einerseits und den Faltdomen 25 andererseits in einer Übemahmeposition gehalten. Durch achsparallele Verschiebung der Hülsentasche 54 wird die bereitgehaltene Hülse 20 aufgenommen.The pocket turret 53 is provided along the circumference with receptacles for the sleeve 20, namely with sleeve pockets 54. Both brackets, namely folding mandrels 25 on the one hand and sleeve pockets 54 on the other hand are conveyed along endless, namely circular trajectories, with a folding mandrel 25 each associated sleeve pocket 54 in exact alignment with distance opposite. During the rotation of the two turrets 24 and 53, as far as applicable, convolutions are carried out or displacement movements. The transfer of the sleeves from the intermediate turret 24 takes place in such a way that the sleeve pockets 54 are in a retracted in the axis-parallel direction position. The sleeves 20 are now held in an area between the sleeve pockets 54 on the one hand and the folding mandrels 25 on the other hand in a take-up position. By axially parallel displacement of the sleeve pocket 54, the prepared sleeve 20 is received.

Wenn im Bereich der Faltdorne 25 der Schieber 13 entsprechend Fig. 8 gefaltet ist, also mit an dem Zigarettenblock 10 anliegenden Stecklasche 18, jedoch mit ausgestreckter, noch nicht gefalteter Stirnlasche 17, werden die beiden Packungseinheiten einander zugeführt. Dies geschieht in der Weise, dass die Halterung der Hülse 20, nämlich die Hülsentasche 54, in achsparalleler Richtung, also quer zur Förderrichtung, zum Faltdorn 25 hin verschoben wird in eine Position gemäß Fig. 6 bis Fig. 9. Die Hülsentasche 54 hat in dieser Stellung einen relativ geringen Abstand vom zugekehrten freien Ende des Faltdorns 25. Die Hülsentaschen 54 sind auf der dem Faltdorn 25 zugekehrten Seite offen, so dass die Hülse 20 mit einer freien Öffnung dem Faltdorn 25 zugekehrt ist. Auf der gegenüberliegenden Seite ist die Hülsentasche 54 an einem Tragstück 55 angebracht, welches seinerseits mit dem Taschenrevolver 53 verbunden ist. Die Hülsentasche 54 besteht weiterhin aus einer radial innen liegenden Tragwand 56 und einer gegenüberliegenden, kürzeren Außenwand 57. Die Vorderwand 21 und Rückwand 22 der Hülse 20 liegen an der Tragwand 56 und der Außenwand 57 an. Die exakte Position der Hülse 20 innerhalb der Hülsentasche 54 wird durch obere und untere Anschläge 58 gewährleistet, die paarweise an der Innenseite von Tragwand 56 einerseits und Außenwand 57 andererseits angeordnet sind. Die Hülse 20 liegt mit einer freien Kante an diesen Anschlägen an.If, in the region of the folding mandrels 25, the slider 13 is folded as shown in FIG. 8, ie with the insertion tab 18 resting on the cigarette block 10, but with the end tab 17 not yet folded, the two packing units are fed to one another. This is done in such a way that the holder of the sleeve 20, namely the sleeve pocket 54, in the axis-parallel direction, ie transversely to the conveying direction, the folding mandrel 25th The sleeve pocket 54 has in this position a relatively small distance from the facing free end of the folding mandrel 25. The sleeve pockets 54 are open on the folding mandrel 25 facing side, so that the Sleeve 20 is facing the folding mandrel 25 with a free opening. On the opposite side, the sleeve pocket 54 is attached to a support piece 55, which in turn is connected to the pocket turret 53. The sleeve pocket 54 further consists of a radially inner support wall 56 and an opposite, shorter outer wall 57. The front wall 21 and rear wall 22 of the sleeve 20 abut the support wall 56 and the outer wall 57 at. The exact position of the sleeve 20 within the sleeve pocket 54 is ensured by upper and lower stops 58, which are arranged in pairs on the inside of the support wall 56 on the one hand and outer wall 57 on the other. The sleeve 20 abuts against these stops with a free edge.

In der zum Faltdorn 25 benachbarten Stellung der Hülsentasche 54 mit Hülse 20 wird die andere Packungseinheit in die Hülse 20 eingeschoben. Zu diesem Zweck wird innerhalb des Faltdorns 25 ein Stößel 59 wirksam, der die Zigarettengruppe 12 erfasst und am freier Ende aus dem Faltdorn 25 ausschiebt. Dabei wird der außen auf dem Faltdorn 25 gefaltete Innenzuschnitt 11 und der teilweise gefaltete Schieber 13 mit von dem Faltdorn 25 abgezogen. Diese Packungseinheit wird dabei in die offene Hülse 20 eingeschoben (Fig. 8, Fig. 9).In the position adjacent to the folding mandrel 25 of the sleeve pocket 54 with sleeve 20, the other packing unit is inserted into the sleeve 20. For this purpose, a plunger 59 is effective within the folding mandrel 25, which detects the cigarette group 12 and ausschiebt at the free end of the folding mandrel 25. Here, the folded on the outside of the folding mandrel 25 inner blank 11 and the partially folded slider 13 is subtracted from the folding mandrel 25. This packing unit is inserted into the open sleeve 20 (FIGS. 8, 9).

Innerhalb der Hülse 20 befindet sich ein mit der Hülsentasche 54 verbundener Gegenhalter 60, der über eine Schubstange 61 verschiebbar ist. Dieser den Querschnitt der Hülse 20 weitgehend ausfüllende Gegenhalter 60 wird zunächst bis an das freie Ende der Hülse 20 bewegt. Die durch Abschieben von dem Faltdorn 25 zugeführte Einheit kommt mit der Bodenlasche 16 des Schiebers 13 zunächst zur Anlage an diesem Gegenhalter 60 (Fig. 6, Fig. 7). Dieser Bereich des Schiebers 13, nämlich Bodenlasche 16 und Stecklasche 18, werden so in der packungsgerechten Form fixiert (Fig. 7).Within the sleeve 20 is a connected to the sleeve pocket 54 counter-holder 60, which is displaceable via a push rod 61. This counter-holder 60, which largely fills the cross-section of the sleeve 20, is initially moved as far as the free end of the sleeve 20. The unit supplied by pushing away from the folding mandrel 25 initially comes to bear against the bottom tab 16 of the slide 13 against this counterholder 60 (FIG. 6, FIG. 7). This area of the slide 13, namely bottom flap 16 and insertion tab 18, are thus fixed in the package-oriented form (FIG. 7).

Am Gegenhalter 60 ist beidseitig jeweils ein Führungsorgan angeordnet, nämlich schmale, dünnwandige Führungsstege 62. Diese sind in Richtung auf den Faltdorn 25 leicht divergierend ausgebildet. Sie dienen zum Erfassen und Halten der beiden Seitenstege 15 des Schiebers 13 in der Anlagestellung an dem Zigarettenblock 10.On the counter-holder 60, a guide member is arranged on both sides, namely narrow, thin-walled guide webs 62. These are slightly divergent in the direction of the folding mandrel 25. They serve for detecting and holding the two side webs 15 of the slider 13 in the contact position on the cigarette block 10th

Der Gegenhalter 60 wird entsprechend der Zuführung der Packungseinheit vom Faltdorn 25 in die Hülse 20 innerhalb derselben zurückgezogen, und zwar bis in eine Stellung, in der der überwiegende Teil von Zigarettenblock 10 und Schieber 13 innerhalb der Hülse 20 positioniert ist (Fig. 9). Des Weiteren kehrt die Hülsentasche 54 in die Ausgangsstellung zurück, nämlich mit größerem Abstand von dem Faltdorn 25 (Fig. 10).The anvil 60 is withdrawn in accordance with the delivery of the packing unit from the folding mandrel 25 in the sleeve 20 within the same, to a position in which the majority of the cigarette block 10 and slide 13 is positioned within the sleeve 20 (Fig. 9). Furthermore, the sleeve pocket 54 returns to the starting position, namely at a greater distance from the folding mandrel 25 (FIG. 10).

In dieser Stellung werden zunächst der Innenzuschnitt 11 und danach der Schieber 13 fertig gefaltet. In der Position gemäß Fig. 10 sind innenliegende Stirnfaltlappen bereits gefaltet. Längsfaltlappen 63 der Stirnwand sind achsparallel gerichtet. Durch Faltorgane bekannter Ausführung werden die Längsfaltlappen 63 nacheinander bei Drehung des Taschenrevolvers 53 gefaltet zur Bildung der in Fig. 1 erkennbaren typischen Stimfaltung des Zigarettenblocks 10. Danach wird der stirnseitige Bereich des Schiebers 13 gefaltet, nämlich die Stirnlasche 17 und die an dieser angebrachte Stecklasche 19, und zwar durch eine ortsfest in der Bewegungsbahn der Packungen bzw. Hülsentaschen 54 positionierte Faltweiche 64 (Fig. 11). Die Einheit Zigarettenblock und Schieber 13 wird nun vollständig in die Hülse 20 eingeschoben, und zwar durch Bewegung der Hülsentasche 54 mit der Hülse 20 in Richtung auf den Faltdorn 25, wobei Zigarettenblock 10 und Schieber 13 auf der winkelförmigen Faltweiche 64 abgestützt sind. Die fertigen Zigarettenpackungen werden nun von dem Taschenrevolver 53 abgegeben an einen Abförderer 65.In this position, first the inner blank 11 and then the slider 13 are finished folded. In the position according to FIG. 10, inner front fold flaps are already folded. Longitudinal folding tabs 63 of the end wall are directed axially parallel. By folding members of known design, the longitudinal folding tabs 63 are successively folded upon rotation of the pocket turret 53 to form the recognizable in Fig. 1 typical Entfaltung the cigarette block 10. Thereafter, the frontal region of the slider 13 is folded, namely the end flap 17 and attached thereto the insertion tab 19th , and by a fixedly in the movement path of the packages or sleeve pockets 54 positioned folding switch 64 (Fig. 11). The unit cigarette block and slider 13 is now fully inserted into the sleeve 20, by movement of the sleeve pocket 54 with the sleeve 20 in the direction of the folding mandrel 25, wherein the cigarette block 10 and slider 13 are supported on the angle-shaped Faltweiche 64. The finished cigarette packs are now discharged from the pocket turret 53 to a discharge conveyor 65th

In analoger Weise geht die Fertigung von Zigarettenpackungen des Typs Klappschachtel (Fig. 2) von statten. Die typische Klappschachtel besteht aus einem einstückigen Zuschnitt 69 zur Bildung von Schachtelteil 70 und Deckel 71. Innerhalb des Schachtelteils 70 ist ein hier aus einem gesonderten Zuschnitt bestehender Kragen 72 fixiert. Dieser umgibt den oberen Teil des Zigarettenblocks 10 mit Kragen-Vorderwand 73 und Kragen-Lappen 74, 75. Der Kragen 72 ist U-förmig gefaltet, wobei die beiden Kragen-Lappen 74, 75 im Bereich von Seitenwänden liegen.The production of cigarette packs of the folding box type (FIG. 2) proceeds in an analogous manner. The typical folding box consists of a one-piece blank 69 for forming box part 70 and lid 71. Within the box part 70, a collar 72 consisting of a separate blank is fixed. This surrounds the upper part of the cigarette block 10 with collar front wall 73 and collar flaps 74, 75. The collar 72 is folded in a U-shape, with the two collar flaps 74, 75 lying in the region of side walls.

Der typische Zuschnitt 69 für eine Klappschachtel ergibt sich insbesondere aus Fig. 14 a). Danach sind in einem mittleren Teil des langgestreckten Zuschnitts Vorderwand 76, Boden 77, Rückwand 78, Deckel-Rückwand 79, Stirnwand 80, Deckel-Vorderwand 81 und Deckel-Innenlappen 82 als aufeinanderfolgende durch Faltlinien markierte Felder gebildet. Äußere Seitenlappen 83, innere Seitenlappen 84, Boden-Ecklappen 85, Deckel-Seitenlappen 86 (außen), Deckel-Seitenlappen 87 (innen) sowie Deckel-Ecklappen 88 erstrecken sich zu beiden Seiten des Zuschnitts 69.The typical blank 69 for a folding box results in particular from Fig. 14 a). Thereafter, in a central portion of the elongate blank, front wall 76, bottom 77, rear wall 78, lid rear wall 79, end wall 80, lid front wall 81 and lid inner tabs 82 are formed as successive panels marked by fold lines. Outer side tabs 83, inner side tabs 84, bottom corner tabs 85, lid side tabs 86 (outside), lid side flaps 87 (inside) and lid corner flaps 88 extend to both sides of the blank 69.

Die Fertigung der so ausgebildeten Klappschachtel erfolgt in der Weise, dass der vorstehend beschriebene Zuschnitt die eine Packungseinheit und die Zigarettengruppe 12 mit Innenzuschnitt 11, also der Zigarettenblock 10 mit Kragen 72 die zweite Packungseinheit bildet. Beide Packungseinheiten werden getrennt voneinander, aber in synchron gesteuerten Arbeitsschritten gefertigt bzw. vorbereitet und miteinander vereinigt. Die Fertigung bzw. Vorbereitung erfolgt während des kontinuierlichen Transports entlang kreisförmiger Bewegungsbahnen.The manufacture of the folding box designed in this way takes place in such a way that the blank described above forms the one packing unit and the cigarette group 12 with inner blank 11, that is the cigarette block 10 with collar 72, the second packing unit. Both packing units are manufactured separately from each other but in synchronously controlled working steps and combined with each other. The production or preparation takes place during the continuous transport along circular trajectories.

Der Ablauf der Faltschritte beider Packungseinheiten ist schematisch in Fig. 14 gezeigt, wobei die gleichzeitig vollzogenen Schritte einander gegenübergestellt sind. Als Erstes wird der Deckel-Innenlappen 82 des Zuschnitts umgefaltet (Fig. 14 b)). Danach werden seitliche Faltlappen aufgerichtet, nämlich die innenliegenden Seitenlappen 84 und 87 sowie Ecktappen 85 und 88. Die Boden-Ecklappen 85 werden sodann in eine quergerichtele nämlich der Packung entsprechenden Position gefaltet (Fig. 14 c)). Gemäß Fig. 14 d) wird ein Teil des Zuschnitts als Schenkel aufgerichtet, nämlich Boden 77 mit Vorderwand 76 und Seitenlappen 83. Dieser Schenkel wird sodann nochmals umgefaltet bis zur Anlage an den aufgerichteten inneren Seitenlappen 84 bzw. Boden-Ecklappen 86. Nunmehr werden die äußeren Seitenlappen 83 bis zur Anlage an den inneren Seitenlappen 84 gefaltet (Fig. 14 f)). Dadurch entsteht ein einseitig, nämlich oben offenes, hülsenförmiges Packungsteil, nämlich der Schachtelteil 70. In diesen wird nun die Einheit aus Zigarettenblock 10 und Kragen 72 teilweise eingeschoben (Position Fig. 14 j)). Nach Durchführung abschließender Faltschritte wird die innere Packungseinheit vollständig in den weitgehend fertiggefalteten Zuschnitt der Klappschachtel eingeschoben. Diese wird nun durch weitere Faltschritte im Bereich des Deckels 71 komplettiert - Fig. 14 k) bis Fig. 14 m).The sequence of the folding steps of both packing units is shown schematically in FIG. 14, wherein the simultaneously executed steps are contrasted with one another. First, the lid inner tab 82 of the blank is folded over (Figure 14b)). Thereafter, side folding flaps are erected, namely the inner side flaps 84 and 87 and corner flaps 85 and 88. The bottom corner flaps 85 are then folded into a position which is transverse to the packing namely (Fig. 14c)). According to Fig. 14 d), a part of the blank is erected as a leg, namely bottom 77 with front wall 76 and side tabs 83. This leg is then folded over again until it rests against the upright inner side lobe 84 and bottom corner tabs 86 outer side tabs 83 folded up against the inner side tabs 84 (Figure 14f)). This results in a one-sided, namely open at the top, sleeve-shaped packing part, namely the box part 70. In these, the unit of cigarette block 10 and collar 72 is now partially inserted (position Fig. 14 j)). After completion of final folding steps, the inner packing unit is completely inserted into the largely finished folded blank of the folding box. This is now completed by further folding steps in the area of the lid 71 - Fig. 14 k) to Fig. 14 m).

Die beiden Packungseinheiten werden im Bereich paralleler Bewegungsbahnen vorbereitet. Der Zigarettenblock 10 mit Kragen 72 wird durch einen Faltrevolver transportiert und gefaltet, nämlich durch den Dornrevolver 24. Dieser ist analog zu dem Dornrevolver 24 der Fig. 3 bzw. Fig. 4 ausgebildet. An Stelle der Schieberstation 33 ist hier oberhalb des in vertikaler Ebene umlaufende Dornrevolvers 24 eine Kragenstation 89 gebildet. Im Bereich derselben werden ungefaltete Zuschnitte des Kragens 72 auf einem Kragenförderer 90 zugeführt und analog zum Schieber 13 in Radialrichtung dem Dornrevolver 24 übergeben sowie an einen Faltdorn 25 bzw. einen Innenzuschnitt 11 angelegt. Der in Transportrichtung des Kragens 72 vornliegende Kragenlappen 74 wird an die in Förderrichtung des Dornrevolvers 24 vornliegende Seitenwand 37 des Faltdorns angelegt und in dieser Position durch ein bewegbares Halteorgan fixiert, nämlich durch eine Andrückwalze 39. Danach wird der Kragen 72 durch weitere Faltorgane, einschließlich Faltrad 41, U-förmig um den Innenzuschnitt 11 bzw. den Faltdorn 25 herumgefaltet (Fig. 15). Die Gesamtheit der Fertigungs- bzw. Faltschritte im Bereich des Dornrevolvers 24 sind in Fig. 14 b) bis Fig. 14 h) schematisch im Ablauf dargestellt.The two packing units are prepared in the area of parallel trajectories. The cigarette block 10 with collar 72 is transported and folded by a folding turret, namely by the mandrel turret 24. This is analogous to the mandrel turret 24 of Fig. 3 and Fig. 4 is formed. Instead of the slide station 33, a collar station 89 is formed here above the mandrel turret 24, which rotates in the vertical plane. In the area of the same are unfolded blanks of the collar 72 on a collar conveyor Fed 90 and analogously to the slide 13 in the radial direction of the mandrel turret 24 and applied to a folding mandrel 25 and an inner blank 11. The front in the transport direction of the collar 72 collar tabs 74 is applied to the forward direction of the mandrel turret 24 side wall 37 of the folding mandrel and fixed in this position by a movable holding member, namely by a pressure roller 39. Thereafter, the collar 72 by further folding organs, including folding 41, U-shaped around the inner blank 11 and the folding mandrel 25 folded around (Fig. 15). The entirety of the manufacturing or folding steps in the area of the mandrel turret 24 are shown schematically in the flow in FIG. 14 b) to FIG. 14 h).

Die Vorbereitung bzw. Fertigung der äußeren Packungseinheit, nämlich die Faltschritte des Zuschnitts der Klappschachtel, werden in mehreren Bereichen vollzogen, wobei der Zuschnitt mehrere Förderer bzw. Revolver durchläuft, in deren Bereich einzelne Faltschritte durchgeführt werden. Die Vorrichtung ist in ihrer Gesamtheit schematisch in Fig. 13 gezeigt, wobei die Fertigung der inneren Packungseinheit in einer ersten Arbeitsebene, festgelegt durch den Dornrevolver 24 und die Fertigung der äußeren Packungseinheit in einer hierzu paralleren, versetzten zweiten Arbeitsebene stattfindet, die durch eine Anzahl von aufeinanderfolgenden Revolvern und letztendlich durch einen Taschenrevolver 53 bestimmt ist.The preparation or production of the outer packing unit, namely the folding steps of the blanking of the folding box, are carried out in several areas, wherein the blank passes through a plurality of conveyors or turrets, in the region of which individual folding steps are carried out. The apparatus is shown schematically in its entirety in Fig. 13, wherein the manufacture of the inner packing unit takes place in a first working plane defined by the mandrel turret 24 and the manufacture of the outer packing unit in a staggered second working plane parallel thereto, represented by a number of successive revolvers and ultimately by a pocket turret 53 is determined.

Die Zuschnitte für die Klappschachtel werden als fortlaufende Materialbahn 91 mit quer zu dieser gerichteten Zuschnitten zugeführt (zum Beispiel entsprechend US 4 898 569). Im Bereich eines aufwärts gerichteten Förderabschnitts der Materialbahn 91 werden die Deckel-Innenlappen 82 fortlaufend durch bekannte, ortsfeste Faltorgane gefaltet. Ein Überwachungsorgan 92 kontrolliert die korrekte Faltung der Deckel-Innenlappen 82.The blanks for the folding box are fed as a continuous material web 91 with blanks directed transversely thereto (for example according to US Pat. No. 4,898,569). In the region of an upwardly directed conveyor section of the material web 91, the lid inner tabs 82 are continuously folded by known, stationary folding members. A monitoring member 92 controls the correct folding of the lid inner tabs 82.

Im Bereich eines ersten Revolvers, nämlich eines Trennrevolvers 93 werden die einzelnen Zuschnitte gemäß Fig. 14 a) nacheinander von der Materialbahn 91 abgetrennt. Der Trennrevolver 93 weist zu diesem Zweck Halteorgane für die Materialbahn 91 bzw. die einzelnen Zuschnitte auf. Es handelt sich dabei um je einem Zuschnitt zugeordnete Halter 94. Diese weisen an der radial nach außen gerichteten Seite Saugorgane 95 auf zum Erfassen und Halten jeweils eines Zuschnitts.In the area of a first turret, namely a separating turret 93, the individual blanks according to FIG. 14 a) are successively separated from the material web 91. The separating turret 93 has holding members for the material web 91 or the individual blanks for this purpose. These are each assigned to a blank holder 94. These have on the radially outward side suction members 95 for detecting and holding each one blank.

Zum Abtrennen der Zuschnitte 69 von der Materialbahn 91 arbeiten Trennorgane mit dem Trennrevolver 93 zusammen, nämlich Trennwalzen 96, 97. Diese sind mit einem Abstand in Umfangsrichtung des Trennrevolvers 33 voneinander angeordnet, entsprechend der Breite eines Zuschnitts. Die Trennwalzen 96, 97 drücken jeweils Zuschnitte an die Halter 94. Aufgrund unterschiedlicher Drehgeschwindigkeiten - die zweite Trennwalze 97 hat eine größere Umfangsgeschwindigkeit als die Trennwalze 96 - wird der jeweils vordere Zuschnitt von der Materialbahn 91 abgetrennt und sodann durch einen Halter 94 mitgeführt.For separating the blanks 69 of the material web 91 separating members work together with the separating turret 93, namely separating rollers 96, 97. These are spaced from each other with a distance in the circumferential direction of the separating turret 33, corresponding to the width of a blank. The separation rollers 96, 97 each press blanks to the holder 94. Due to different rotational speeds - the second separation roller 97 has a greater peripheral speed than the separation roller 96 - the respective front blank is separated from the web 91 and then carried by a holder 94.

Die einzelnen Zuschnitte 69 werden von dem Trennrevolver 93 an einen nachfolgenden Revolver übergeben, nämlich an einen ersten Faltrevolver 98. Dieser nimmt jeweils einen Zuschnitt durch eine Revolvertasche 99 auf. Während des Transport der Zuschnitte durch diesen Faltrevolver 98 werden die in Fig. 14 c) bis Fig. 14 f) dargestellten Faltschritte vollzogen.The individual blanks 69 are transferred from the separating turret 93 to a subsequent revolver, namely to a first folding turret 98. This one each takes a blank through a turret pocket 99. During the transport of the blanks through this folding turret 98, the folding steps shown in FIG. 14 c) to FIG. 14 f) are completed.

Der demnach weitgehend gefaltete Zuschnitt 69 wird sodann von dem ersten Faltrevolver 98 an einen zweiten-Faltrevolver 100 übergeben. Bei der Übergabe werden die seitwärtsgerichteten äußeren Seitenlappen 83 umgefaltet zur Anlage an den innenliegenden Seitenlappen 84.The largely folded blank 69 is then transferred from the first folding turret 98 to a second folding turret 100. Upon transfer, the laterally directed outer side flaps 83 are folded over to rest against the inner side flaps 84.

Der Faltrevolver 100 führt die Zuschnitte 69 in der Faltposition gemäß Fig. 14 g) dem gleichachsig zum Dornrevolver 24 positionierten Taschenrevolver 53 zu. Dieser ist - analog zum Ausführungsbeispiel gemäß Fig. 3 bis Fig. 11 - mit Zuschnitttaschen 101 bestückt, die in achsparalleler Richtung verschiebbar sind und in einer zurückgezogenen Ausgangsstellung eine dritte Arbeitsebene bilden.The folding turret 100 guides the blanks 69 in the folding position according to FIG. 14 g) to the pocket turret 53 positioned equiaxially to the mandrel turret 24. This is - similarly to the embodiment of FIG. 3 to FIG. 11 - equipped with blank pockets 101 which are displaceable in the direction parallel to the axis and form a third working plane in a retracted initial position.

Aufbau und Arbeitsweise der Faltrevolver 98 und 100 sind nur schematisch in Fig. 16, Fig. 17, Fig. 18 und Fig. 19 dargestellt. Faltschritte werden insbesondere bei der Übergabe von einem Revolver zum anderen durchgeführt. So ist in Fig. 16 gezeigt, dass die im Bereich des Trennrevolvers 93 flachen Zuschnitte bei Übernahme durch eine Revolvertasche 99 des Faltrevolvers 98 gefaltet werden, und zwar werden seitliche Faltlappen gemäß Fig. 14 c) aufgerichtet durch seitliche Taschenwände 102. Bei diesem Faltschritt wird ein zunächst radial nach außen bewegter Taschenboden 103 im Verlauf des Faltvorgangs radial nach innen bewegt, also in die Revolvertasche 99 hinein. In Axialrichtung sind die Revolvertaschen 99 so bemessen, dass Bereiche des Deckels und der Vorderwand 76 nicht erfasst sind (Fig. 14 c)). Bei der Förderbewegung in Pfeilrichtung gemäß Fig. 16 werden die in einem ersten Faltschritt aufgerichteten Boden-Ecklappen 85 quergestellt (Fig. 14 d)).Construction and operation of the folding turrets 98 and 100 are shown only schematically in FIGS. 16, 17, 18 and 19. Folding steps are carried out in particular when transferring from one revolver to another. Thus, it is shown in FIG. 16 that the blanks which are flat in the region of the separating turret 93 are folded when taken over by a turret pocket 99 of the folding turret 98, namely lateral folding tabs according to FIG. 14 c) are set up by lateral pocket walls 102. In this folding step an initially moved radially outward pocket bottom 103 moves radially inward in the course of the folding process, ie in the turret pocket 99 inside. In the axial direction are the Turret pockets 99 sized so that areas of the lid and the front wall 76 are not detected (Fig. 14 c)). During the conveying movement in the direction of the arrow according to FIG. 16, the bottom corner flaps 85 erected in a first folding step are transposed (FIG. 14 d)).

Während des Transports der Zuschnitte 69 durch den ersten Faltrevolver 98 wird durch bekannte, ortsfeste Faltmittel ein aus Boden 77, Vorderwand 76 und mit diesen verbundenen Faltlappen bestehender Teil des Zuschnitts zunächst aufgerichtet (Fig. 14 e)) und sodann bis zur Position etwa parallel zur Rückwand 78 gefaltet (in Fig. 14 f) gezeigte Position). So wird der Zuschnitt an den zweiten Faltrevolver 100 übergeben. Bei diesem Übertragungsschritt werden wiederum seitliche Lappen gefaltet, nämlich die äußeren Seitenlappen 83, und zwar in die packungsgerechte Position gemäß Fig. 14 g). Beim Einführen der (gefalteten) Zuschnitte in die Zuschnitttasche 101 werden bewegbare, nämlich schwenkbare Taschenwände 104 wirksam. Diese werden aus einer gespreizten, nach außen divergierenden Relativstellung (Fig. 17, Fig. 18) während des Übergabeschritts der Zuschnitte in eine parallele Schließstellung bewegt. Dabei werden nacheinander die beiden Seitenlappen 83 gefaltet. In dieser weitgehend fertiggestellten Formation des Zuschnitts gemäß Fig. 14 g) wird der Zuschnitt mit fertiggefaltetem Schachtelteil 70 an den Hauptrevolver, nämlich an den Taschenrevolver 53, übergeben.During the transport of the blanks 69 through the first folding turret 98, a part of the blank consisting of bottom 77, front wall 76 and folding flaps connected thereto is first erected by known, stationary folding means (FIG. 14 e)) and then up to the position approximately parallel to the Rear wall 78 folded (shown in Fig. 14 f) position). Thus, the blank is transferred to the second folding turret 100. In this transfer step, in turn, side flaps are folded, namely the outer side flaps 83, in the package-oriented position shown in FIG. 14 g). When inserting the (folded) blanks in the blank pocket 101 movable, namely pivotable bag walls 104 are effective. These are moved from a spread, outwardly diverging relative position (Fig. 17, Fig. 18) during the transfer step of the blanks in a parallel closed position. The two side tabs 83 are successively folded. In this largely completed formation of the blank according to FIG. 14 g), the blank with finished folded box part 70 is transferred to the main turret, namely to the pocket turret 53.

Der Taschenrevolver 53 bildet mit dem Dornrevolver 24 auch bei diesem Ausführungsbeispiel eine Revolvereinheit. Der Taschenrevolver 53 ist mit zwei in Axialrichtung versetzten Halteorganen für die Packungen bzw. gefalteten Zuschnitte ausgestattet. In der (zweiten) Arbeitsebene sind paarweise einander zugeordnete Haltebacken 106 für jeden Zuschnitt vorgesehen. Diese erfassen die vom Faltrevolver 100 zugeführten Zuschnitte in der Faltstellung gemäß Fig. 14 g), und zwar im Bereich von einander gegenüberliegenden Seitenwänden des Schachtelteils 70 und Deckels 71. Packungstaschen 107 sind am Umfang des Taschenrevolvers 53 angeordnet, und zwar jeweils in achsparalleler Richtung auf einen Faltdorn 25 des benachbarten Dornrevolvers 24 ausgerichtet. Packungstaschen 107 und Faltdorne 25 sind demnach auf einer Kreisfläche desselben Durchmessers angeordnet. Die Packungstaschen 107 sind in achsparalleler Richtung verschiebbar, und zwar aus einer Ausgangsstellung (Fig. 20, Fig. 21), die der dritten Arbeitsebene entspricht, in eine Position zur Übernahme der gefalteten Zuschnitte (zweite Arbeitsebene) entsprechend Fig. 22, Fig. 23. Die gefalteten Zuschnitte bzw. (leeren) Packungen werden dabei zunächst durch die Haltebacken 106 bereitgehalten (Fig. 20, Fig. 21). Die Haltebacken 106 sind schwenkbar gelagert, und zwar an verhältnismäßig langen Schwenkarmen 108, 109, die mit Rücksicht auf eine angestrebte Kinematik unterschiedlich lang sind und etwa parallel zueinander schwenkbar gelagert sind. Ein den Zuschnitten bzw. Packungen zugekehrter Bereich der Schwenkarme 108, 109 ist U-förmig gestaltet, einschließlich der Haltebacken 106, unter Bildung einer etwa mittigen Ausnehmung 110.The pocket turret 53 forms with the mandrel turret 24 in this embodiment, a turret unit. The pocket turret 53 is equipped with two offset in the axial direction retaining members for the packages or folded blanks. In the (second) work plane, mutually associated holding jaws 106 are provided for each blank. These detect the blanks supplied by the folding turret 100 in the folded position according to FIG. 14 g), in the region of opposite side walls of the box part 70 and lid 71. Packing pockets 107 are arranged on the circumference of the pocket turret 53, in each case in the axis-parallel direction a folding mandrel 25 of the adjacent mandrel turret 24 aligned. Packing pockets 107 and folding mandrels 25 are therefore arranged on a circular area of the same diameter. The packing pockets 107 are displaceable in the direction parallel to the axis, namely from a starting position (FIG. 20, FIG. 21) corresponding to the third working plane into a position for taking over the folded blanks (second working plane) according to FIG. 22, FIG The folded blanks or (empty) packs are Initially held by the holding jaws 106 (Fig. 20, Fig. 21). The holding jaws 106 are pivotally mounted, namely on relatively long pivot arms 108, 109 which are different in length with regard to a desired kinematics and are mounted approximately parallel to each other pivotally. A portion of the pivot arms 108, 109 facing the blanks or packs is U-shaped, including the holding jaws 106, forming an approximately central recess 110.

Während die Zuschnitte/Packungen in einer Position gemäß Fig. 20, Fig. 21 bereitgehalten werden, erfolgt die Übernahme durch die Packungstaschen 107, indem diese in achsparalleler Richtung verschoben werden. Die Packungstaschen 107 bestehen aus einer radial innenliegenden Bodenplatte 111, aus fingerartigen Seitenführungen 112 und einer radial außenliegenden Oberführung 113. Bodenplatte 111 und Oberführung 113 liegen einander gegenüber im Bereich von (radial innenliegender) Rückwand 78 einerseits und der radial außenliegenden Vorderwand 76 andererseits. Die Bodenplatte 111 erstreckt sich bis in den Bereich der Deckel-Rückwand 79, während die Oberführung 113 eine geringere Abmessung aufweist. Die - noch nicht durch Klebung miteinander verbundenen - Seitenlappen 83, 84 werden durch die Seitenführung 112 erfasst. Die tritt bei der Verschiebung der Packungstasche 107 in eine nutartige Vertiefung 114 der beiden Haltebacken 106 ein. Nach Übernahme einer Packung bzw. eines Zuschnitts durch eine Packungstasche 107 können die Haltebacken 106 auseinanderbewegt werden unter Freigabe der Packung bzw. des Zuschnitts 69.While the blanks / packs are kept ready in a position according to FIG. 20, FIG. 21, they are taken over by the packing pockets 107 by being displaced in the axis-parallel direction. The packing pockets 107 consist of a radially inner bottom plate 111, of finger-like side guides 112 and a radially outer upper guide 113. Base plate 111 and upper guide 113 lie opposite each other in the area of (radially inner) rear wall 78 on the one hand and the radially outer front wall 76 on the other hand. The bottom plate 111 extends into the region of the lid rear wall 79, while the upper guide 113 has a smaller dimension. The side tabs 83, 84, which are not yet joined together by adhesive bonding, are grasped by the side guide 112. This occurs during the displacement of the packing pocket 107 into a groove-like depression 114 of the two holding jaws 106. After taking over a package or a blank through a packing bag 107, the holding jaws 106 can be moved apart releasing the package or the blank 69.

Es beginnt nun die Vereinigung der beiden Packungseinheiten. Zu diesem Zweck wird in der im Zusammenhang mit dem Ausführungsbeispiel gemäß Fig. 3 bis Fig. 11 beschriebenen Weise die innere Packungseinheit vom Faltdorn 25 abgeschoben, und zwar einschließlich Kragen 72. Zuvor sind noch nicht gefaltete Teile des Deckels 71, nämlich Deckel-Rückwand 79, Stirnwand 80 und Deckel-Vorderwand 81 mit Deckel-Innenlappen 82 radial nach innen verformt unter Bildung einer trichterartigen Position (Fig. 23). Des Weiteren sind seitliche Faltlappen, nämlich Deckel-Ecklappen 88, ebenfalls in eine schräggerichtete, trichterförmige Position geformt (Fig. 22). Die noch nicht durch Klebung miteinander verbundenen Seitenlappen 83, 84 sind geringfügig gegeneinander verschoben, so dass der Schachtelteil 70 zur offenen Seite hin durch Schrägstellung der Vorderwand 76 leicht trichterförmg geöffnet ist. Die Oberwand bzw. Oberführung 113 der Packungstaschen 107 ist entsprechend innenseitig abgeschrägt. Nunmehr kann der Zigarettenblock 10 durch den Stößel 59 in die Verpackung eingeschoben werden, und zwar teilweise, nämlich derart, dass ein stimseitiger Bereich des Zigarettenblocks freiliegt (Fig. 24). In achsparalleler Richtung weisende Faltlappen einer stirnseitigen Faltung des Zigarettenblocks 10, nämlich Längsfaltlappen 63, können nun infolge fortgesetzter Drehbewegung der Revolver gefaltet werden unter Bildung der kompletten Stimfaltung des Zigarettenblocks 10. Der noch ungefaltete Teil des Deckels 71, nämlich Stirnwand 80 und Deckel-Vorderwand 81 werden nunmehr in die Schließstellung gefaltet entsprechend Fig. 14 I). Hierzu dient ein ortsfestes, schienenartiges Faltorgan 115 mit winkelförmigem Profil (Fig. 26).It now begins the union of the two packing units. For this purpose, in the manner described in connection with the embodiment according to FIGS. 3 to 11, the inner packing unit is pushed away from the folding mandrel 25, including collar 72. Previously, unfolded parts of the lid 71, namely lid rear wall 79 are not yet folded , End wall 80 and lid front wall 81 with lid inner tabs 82 deformed radially inwardly to form a funnel-like position (Figure 23). Furthermore, lateral folding flaps, namely lid corner flaps 88, are also shaped into an oblique, funnel-shaped position (Figure 22). The not yet interconnected by gluing side tabs 83, 84 are slightly offset from each other, so that the box part 70 is open to the open side by tilting the front wall 76 slightly funnel-shaped. The top wall or upper guide 113 of the packing pockets 107 is correspondingly beveled on the inside. Now the cigarette block 10 are pushed by the plunger 59 into the packaging, in part, namely such that a frontal area of the cigarette block is exposed (FIG. 24). Folding tabs of an end-side folding of the cigarette block 10, namely longitudinal folding tabs 63, pointing in the direction parallel to the axis can now be folded as a result of continued rotational movement of the turret to form the complete creasing of the cigarette block 10. The still unfolded part of the lid 71, namely end wall 80 and lid front wall 81 are now folded into the closed position corresponding to Fig. 14 I). This purpose is served by a stationary, rail-like folding member 115 with an angular profile (FIG. 26).

Der Schachtelteil. 70 der Klappschachtel wird ebenfalls komplettiert, nämlich aus der trichterförmigen Öffnungsstellung (Fig. 23) in die packungsgerechte Position gefaltet bei vollständiger Überdeckung der Seitenlappen 83 und 84. Des Weiteren werden nun die durch Leim miteinander zu verbindenden Faltlappen durch Aktivierung von entsprechenden Leimflächen miteinander verbunden. Zu diesem Zweck sind die Zuschnitte 69 im Bereich von durch Leim miteinander zu verbindenden Faltlappen bei der (industriellen) Fertigung mit Leimflächen versehen, die durch Einwirkung von Wärme und/oder Druck oder auf andere Weise aktiviert bzw. reaktiviert werden können. Beispielsweise können die betreffenden Faltlappen mit Hot-Melt-Leim versehen sein. Nach Komplettierung der Packung (Fig. 26) werden die betreffenden Faltlappen durch Aktivierung der Leimflächen miteinander verbunden.The box part. 70 of the folding box is also completed, namely from the funnel-shaped opening position (Fig. 23) folded into the package-oriented position with complete coverage of the side tabs 83 and 84. Furthermore, the folding tabs to be joined together by glue are now connected by activation of corresponding glue surfaces. For this purpose, the blanks 69 are provided in the area of folding flaps to be joined together by glue in (industrial) production with glue surfaces which can be activated or reactivated by the action of heat and / or pressure or in another way. For example, the respective folding flaps can be provided with hot-melt glue. After completion of the package (Fig. 26) the respective folding flaps are connected by activating the glue surfaces.

Die zuletzt beschriebenen Faltschritte werden bei zurückgezogenen Packungstaschen 107 ausgeführt, also in der dritten Arbeitsebene. In dieser Stellung haben die Packungstaschen 107 einen größeren Abstand von den Faltdornen 25 (Fig. 24 bis Fig. 26). Nach Falten der Längsfaltlappen 63 wird darüber hinaus der Zigarettenblock 10 vollständig in die Verpackung bzw. in den Schachtelteil 70 eingeschoben (Fig. 25). Danach wird der Deckel 71 fertiggestellt.The folding steps described last are carried out with the packing pockets 107 withdrawn, that is to say in the third working plane. In this position, the packing pockets 107 have a greater distance from the folding mandrels 25 (Fig. 24 to Fig. 26). After folding the longitudinal folding tabs 63, moreover, the cigarette block 10 is completely inserted into the packaging or into the box part 70 (FIG. 25). Thereafter, the lid 71 is completed.

Die fertigen Packungen werden von einem Abförderer 116 übernommen und abtransportiert. Dabei wird so vorgegangen, dass die fertigen Packungen durch achsparallele Verschiebung der Packungstaschen 107 in die den Faltdomen 25 zugekehrte Position (mittlere Arbeitsebene) an die Haltebacken 106 zurückgegeben werden. Die Haltebacken werden durch entsprechende Bewegung der Schwenkarme 108, 109 gegen die Seiten der Packungstaschen 107 gefahren. Durch Rückziehen der Packungstaschen 107 in eine Stellung gemäß Fig. 20, Fig. 21 werden die fertigen Packungen an die Haltebacken 106 zurückgegeben. Ein sternförmiger Übergabeförderer 117 kann nun die Packungen 10 durch Eintritt in die Ausnehmung 110 von den Haltebacken 106 übernehmen und dem Abförderer 116 zuführen.The finished packages are taken over by a discharge conveyor 116 and transported away. In this case, the procedure is such that the finished packages are returned to the holding jaws 106 by axially parallel displacement of the packing pockets 107 in the position facing the folding mandrels 25 (middle working plane). The jaws are by appropriate movement of the pivot arms 108, 109 against the sides the pack bags 107 drove. By retracting the packing pockets 107 into a position according to FIG. 20, FIG. 21, the finished packs are returned to the holding jaws 106. A star-shaped transfer conveyor 117 can now take over the packages 10 by entering the recess 110 of the holding jaws 106 and the discharge conveyor 116 out.
