  • the aim of the invention is to improve the preparation of the package contents (cigarette group) during transport to the partially folded package, in such a way that, at the high working speeds, the cigarettes are treated gently on the one hand, but the inside wrapping (tinfoil cut) on the other hand is precise the contents of the pack are folded over. Since during the supply and introduction of the package contents this is subject to considerable accelerations and delays, care should be taken in accordance with the invention to ensure that the package is exactly fixed within a block pocket open at the front and rear during this transport, which is directed towards the folding turret in the radial direction. Above all, care should be taken to ensure that the cigarette blocks fixed in the block pocket are released again without any problems. Finally, the invention is concerned with feeding a (separate) collar blank with the package contents to the folding turret.

Description

Die Erfindung betrifft eine Vorrichtung zum Zuführen von Gruppen von stabförmigen Gegenständen, insbesondere von Zigaretten-Gruppen, zu einer Verpackung (Zigaretten-Packung) sowie zum Einführen in diese gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to a device for feeding groups of rod-shaped objects, in particular cigarette groups, to packaging (cigarette pack) and for introducing them into the packaging according to the preamble of claim 1.

Die Erfindung wendet sich an Verpackungsmaschinen zum Herstellen von Packungen bzw. Verpackungen mit stückigem Packungsinhalt, insbesondere mit einem einzelnen Gegenstand für jede Packung. Bevorzugtes Anwendungsgebiet der Erfindung ist die Herstellung von Zigaretten-Packungen, und zwar hiervon die Herstellung von sogenannten Klappschachteln (Hinge-Lid-Packungen).The invention is applied to packaging machines for producing packs or packagings with piece-like pack contents, in particular with a single object for each pack. The preferred field of application of the invention is the manufacture of cigarette packs, specifically the manufacture of so-called hinged boxes (hinge-lid packs).

Die Erfindung kommt weiterhin vornehmlich bei solchen Verpackungsmaschinen zum Einsatz, bei denen die Verpackung bzw. der Zuschnitt zur Herstellung derselben bereits teilweise gefaltet sind, bevor die Gegenstände zu- und eingeführt werden. Nach dem Einschieben der Gegenstände werden noch weitere, die Packung fertigstellende Faltungen durchgeführt.The invention is also used primarily in packaging machines in which the packaging or the blank for producing the same is already partially folded before the objects are fed in and introduced. After the objects have been pushed in, further folds which complete the pack are carried out.

Ein bevorzugtes Anwendungsbeispiel für die Erfindung ist in der DE-OS 2 440 006 beschrieben. Diese Druckschrift befasst sich mit der Herstellung und Füllung von Klappschachteln für Zigaretten. Ein Zuschnitt für die Herstellung der Packung aus Papier bzw. dünner Pappe wird dabei in eine Tasche eines um eine vertikale Achse umlaufenden Faltrevolvers eingeführt und teilweise gefaltet, bevor der Packungsinhalt (Zigaretten-Gruppe mit Umhüllung durch einen Stanniol-Zuschnitt) in Radialrichtung zum Faltrevolver in die Tasche bzw. in die in dieser angeordneten Packung eingeschoben wird.A preferred application example for the invention is described in DE-OS 2 440 006. This document deals with the manufacture and filling of hinged boxes for cigarettes. A blank for the production of the paper or thin cardboard pack is inserted into a pocket of a folding turret rotating around a vertical axis and partially folded before the contents of the pack (cigarette group with wrapping by a tinfoil blank) in the radial direction towards the folding turret in the bag or is inserted into the package arranged in this.

Bei der Erfindung geht es darum, die Vorbereitung des Packungsinhalts (Zigaretten-Gruppe) während des Transports zur teilgefalteten Pakkung zu verbessern, derart, dass bei den hohen Arbeitsgeschwindigkeiten die Zigaretten einerseits schonend behandelt werden, andererseits aber der Inneneinschlag (Stanniol-Zuschnitt) exakt um den Packungsinhalt herumgefaltet wird. Da während der Zu- und Einführung des Pakkungsinhalts dieser erheblichen Beschleunigungen und Verzögerungen ausgesetzt ist, soll erfindungsgemäss dafür Sorge getragen werden, dass die Packung während dieses in Radialrichtung zum Faltrevolver gerichteten Transports innerhalb einer vorn und rückseitig offenen Blocktasche exakt fixiert ist. Vor allem soll darauf geachtet werden, dass die in der Blocktasche fixierten Zigaretten-Blöcke störungsfrei wieder freigegeben werden. Schliesslich befasst sich die Erfindung mit der Zuführung eines (gesonderten) Kragen-Zuschnitts mit dem Packungsinhalt zum Faltrevolver.The aim of the invention is to improve the preparation of the package contents (cigarette group) during transport to the partially folded package, in such a way that, at the high working speeds, the cigarettes are treated gently on the one hand, but the inside wrapping (tinfoil cut) on the other hand is precise the contents of the pack are folded over. Since during the supply and introduction of the package contents this is subject to considerable accelerations and delays, care should be taken in accordance with the invention to ensure that the package is exactly fixed within a block pocket open at the front and rear during this transport, which is directed towards the folding turret in the radial direction. Above all, care should be taken to ensure that the cigarette blocks fixed in the block pocket are released again without any problems. Finally, the invention is concerned with feeding a (separate) collar blank with the package contents to the folding turret.

Die vorstehende Aufgabe wird durch die kennzeichnenden Massnahmen des Patentanspruches 1 gelöst.The above object is achieved by the characterizing measures of claim 1.

Die erfindungsgemässe Vorrichtung ist - ebenso wie bei der Vorrichtung gemäss der DE-OS 2 440 006 - mit einer hin-und herbewegbaren Tasche ausgerüstet, in der der Packungsinhalt während der letzten Phase des Transportes zum Faltrevolver Aufnahme findet. In dieser Tasche wird die Zigaretten-Gruppe bzw. die in einen (Stanniol-)Zuschnitt eingehüllte Gruppe (Zigaretten-Block) festgehalten, und zwar durch Andrükken des Zigaretten-Blocks und dadurch verursachtes Festklemmen an einer Wandung der Tasche, vorzugsweise an deren Oberwand. Das Andrücken wiederum wird durch Relativbewegung einer gegenüberliegenden Wandung der Tasche bewirkt. Diese Massnahme ist zwar an sich bekannt aus der GB-A-985 185. Dort erfolgt die Festklemmung eines Zigaretten-Blocks jedoch nicht innerhalb einer hin- und herbewegbaren Blocktasche, sondern längs des Transportweges durch die Verpackungsmaschine während eines Bewegungsstopps der teilweise gefalteten Packung mit der Folge, dass diese zur Endfaltung zunächst abgebremst werden muss, um dann wieder beschleunigt zu werden. Dieser durch starke Verzögerungen und Beschleunigungen gekennzeichnete Bewegungsablauf kann zu Beschädigungen der relativ stossempfindlichen Zigaretten führen. Durch die Verwendung einer hin- und herbewegbaren Blocktasche werden die auf die Packung einwirkenden Verzögerungs- und Beschleunigungskräfte in diesem Bereich der Verpackungsmaschine ganz erheblich reduziert. Ferner wird bei der bekannten Vorrichtung vorgeschlagen, die gesamte Oberwand als Klemmplatte auszubilden, wodurch die Gefahr besteht, dass die endgefalteten Packungen durch Adhäsion zwischen Pakkungsoberseite und Klemmplatte beim Hochschwenken derselben mit angehoben werden, wodurch grössere Betriebsstörungen ausgelöst werden können. Ferner werden dadurch die Zigaretten innerhalb der Packung zusätzlich in Richtung quer zu ihrer Längsrichtung belastet.Like the device according to DE-OS 2 440 006, the device according to the invention is equipped with a pocket which can be moved back and forth, in which the contents of the package are accommodated during the last phase of the transport to the folding turret. The cigarette group or the group (cigarette block) encased in a (tinfoil) blank is held in this pocket, namely by pressing the cigarette block and thereby causing it to become stuck to a wall of the pocket, preferably on the upper wall thereof. The pressing in turn is brought about by the relative movement of an opposite wall of the pocket. This measure is known per se from GB-A-985 185. There, however, the clamping of a cigarette block does not take place within a block block which can be moved back and forth, but along the transport path through the packaging machine during a movement stop of the partially folded package with the As a result, this must first be slowed down to the final folding in order to then be accelerated again. This movement, characterized by strong decelerations and accelerations, can damage the relatively shock-sensitive cigarettes. By using a block pocket that can be moved back and forth, the deceleration and acceleration forces acting on the pack are considerably reduced in this area of the packaging machine. Furthermore, it is proposed in the known device to design the entire top wall as a clamping plate, so that there is a risk that the end-folded packs will be lifted by adhesion between the upper side of the package and the clamping plate when it is pivoted upward, as a result of which major malfunctions can be triggered. Furthermore, the cigarettes within the pack are additionally loaded in the direction transverse to their longitudinal direction.

Dieses Problem wird erfindungsgemäss dadurch gelöst, dass die Festklemmung des Zigaretten-Blocks innerhalb der Blocktasche nur durch einen Teilbereich einer Wandung erfolgt, insbesondere durch Aufwärtsbewegung eines Teilbereichs der Bodenwand der Tasche. Dadurch wird der Zigaretten-Block innerhalb der Blocktasche ausreichend gegen die Oberwand gedrückt und während des Transports in der Blocktasche sicher fixiert. Durch den unbeweglich ausgebildeten Teilbereich der Wandung, insbesondere Bodenwand der Tasche, wird eine sichere Freigabe des Zigaretten-Blocks gewährleistet. Der Zigaretten-Block kann durch den beweglichen Teilbereich der Wandung bei Rückbewegung in die Ausserklemm-Stellung nicht mitgenommen werden.This problem is solved according to the invention in that the cigarette block is clamped within the block pocket only by a partial region of a wall, in particular by an upward movement of a partial region of the bottom wall of the pocket. As a result, the cigarette block within the block pocket is pressed sufficiently against the top wall and securely fixed in the block pocket during transport. Reliable release of the cigarette block is ensured by the immovable portion of the wall, in particular the bottom wall of the pocket. The cigarette block cannot be taken along due to the movable part of the wall when moving back into the unclamped position.

Bei der Erfindung wird des weiteren für eine einwandfreie Zuführung eines Kragen-Zuschnitts Sorge getragen. Dieser wird quer zur Transportrichtung des Zigarettenblocks bzw. der Tasche der letzteren zugefördert und oberhalb derselben synchron mit der Tasche weitertransportiert. Während des unmittelbaren Einschubs des Zigaretten- Blocks in die Packung innerhalb der Revolvertasche des Faltrevolvers erfolgt die Absenkung des Kragen-Zuschnitts auf den Zigaretten-Block und die Positionierung auf demselben.In the invention, care is also taken to ensure that a collar blank is correctly fed. This is conveyed transversely to the direction of transport of the cigarette block or the pocket of the latter and transported above it synchronously with the pocket. During the direct insertion of the cigarette block into the pack inside the turret pocket of the folding turret, the Cut the collar onto the cigarette block and position it on it.

Für die exakte Halterung der teilgefalteten Pakkung in der radial nach aussen offenen Revolvertasche sind erfindungsgemäss ebenfalls Massnahmen vorgesehen. Diese bewirken, dass die Packung gegen einen Taschenboden gedrückt wird. Darüber hinaus werden in eine aufrechte Stellung gefaltete Zuschnitteile in eine sich trichterförmig öffnende Position gebracht, so dass der Einschub des Zigaretten-Blocks störungsfrei gewährleistet ist. Des weiteren sind Massnahmen dafür vorgesehen, die den eingeschobenen Zigaretten-Block in der Packung fixieren und dabei eventuelle Positionsdifferenzen ausgleichen.According to the invention, measures are also provided for the exact holding of the partially folded package in the turret pocket which is open radially outwards. These cause the pack to be pressed against the bottom of a pocket. In addition, cut parts folded into an upright position are brought into a funnel-shaped opening position, so that the insertion of the cigarette block is ensured without interference. In addition, measures are provided to fix the inserted cigarette block in the package and to compensate for any differences in position.

Die beschriebene Vorrichtung ist besonders geeignet als Teilaggregat einer Verpackungsmaschine für (quaderförmige) Faltschachteln im Sinne der DE-OS 2 440 006. Bevorzugtes Anwendungsgebiet ist die Herstellung von Klappschachteln, für die zum besseren Verständnis ein Zuschnitt 20 in Fig. 1 gezeigt ist. Dieser ist durch längs- und quergerichtete Faltlinien 21 in einzelne Flächenbereiche aufgeteilt zur Bildung einer Bodenwand 22, einer Vorderwand 23, Seitenlappen 24, einer Rückwand 25, an dieser angeordneten Seitenlappen 26. Die Seitenlappen 24 einerseits sowie 26 andererseits sind bei der fertigen Pakkung zur Bildung von Seitenwänden übereinander gefaltet und durch Klebung miteinander verbunden. Zur Bildung eines Klappdeckels sind Deckelstirnwand 27, Deckelvorderwand 28, an diese anschliessende Aussenzwickel 29, Innenzwickel 30 und Deckelecklappen 31 vorgesehen. Letztere, nämlich Innenzwickel 30 und Deckelecklappen 31, erstrecken sich in Verlängerung der Seitenlappen 24, sind jedoch gegenüber diesen durch einen keilförmigen Einschnitt abgetrennt, der an den Seitenlappen 24 eine schräg gerichtete Endkante 32 bildet. Der Innenzwickel 30 mit dem anschliessenden Deckelecklappen 31 ist mit der Rückwand 25 verbunden.The device described is particularly suitable as a sub-assembly of a packaging machine for (rectangular) folding boxes in the sense of DE-OS 2 440 006. A preferred area of application is the production of folding boxes, for which a blank 20 is shown in FIG. 1 for better understanding. This is divided by longitudinal and transverse fold lines 21 into individual surface areas to form a bottom wall 22, a front wall 23, side tabs 24, a rear wall 25, side tabs 26 arranged thereon. The side tabs 24 on the one hand and 26 on the other hand are for formation in the finished package folded from side walls on top of each other and connected by gluing. In order to form a hinged lid, the end wall 27 of the lid, the front wall 28 of the lid, the outer gusset 29 adjoining it, the inner gusset 30 and the lid corner flap 31 are provided. The latter, namely the inner gusset 30 and the lid corner tabs 31, extend in the extension of the side tabs 24, but are separated from them by a wedge-shaped incision which forms an obliquely directed end edge 32 on the side tabs 24. The inner gusset 30 with the adjoining corner flap 31 is connected to the rear wall 25.

Als weiteres Packungsteil spielt ein Innenzuschnitt (Stanniol-Zuschnitt 33) eine Rolle. Dieser umhüllt den Packungsinhalt, nämlich eine Gruppe von Zigaretten. Diese bilden zusammen mit dem Stanniol-Zuschnitt 33 einen Zigaretten-Block 34, der in die aus dem Zuschnitt 20 gebildete, teilweise gefaltete Packung eingeführt werden soll.An inner blank (tin foil blank 33) plays a role as a further packing part. This envelops the contents of the pack, namely a group of cigarettes. Together with the tinfoil blank 33, these form a cigarette block 34 which is to be inserted into the partially folded package formed from the blank 20.

Die Vor- bzw. Teilfaltung des Zuschnitts 20 für die Aufnahme des Zigaretten-Blocks 34 erfolgt vorzugsweise in der in der DE-OS 2440006 beschriebenen Weise. Der Zuschnitt 20 wird demnach in einen als flacher Teller ausgebildeten Faltrevolver 35 eingeführt, der längs seines Umfangs mit Packungstaschen 36 je zur Aufnahme eines Zuschnitts 20 bzw. einer Packung versehen ist. Die Packungstaschen 36 sind unten durch einen Taschenboden 37 und auf der radial innen liegenden Seite durch eine Innenwand 38 begrenzt, die im vorliegenden Fall durch einen nach unten weisenden Schenkel eines Winkelprofils gebildet wird. An den etwa mittig geteilten Taschenboden 37 schliessen seitlich im wesentlichen radial verlaufende Taschenseitenwände 39 an. Auf der Oberseite sowie auf der radial aussen liegenden Seite sind die Packungstaschen 36 offen.The pre-folding or partial folding of the blank 20 for receiving the cigarette block 34 is preferably carried out in the manner described in DE-OS 2440006. The blank 20 is accordingly inserted into a folding turret 35 designed as a flat plate, which is provided along its circumference with packing pockets 36 each for receiving a blank 20 or a pack. The packing pockets 36 are delimited at the bottom by a pocket bottom 37 and on the radially inner side by an inner wall 38, which in the present case is formed by a leg of an angular profile pointing downwards. The pocket bottom walls 39, which are divided approximately centrally, are connected laterally by essentially radially extending pocket side walls 39. The packing pockets 36 are open on the top and on the radially outer side.

Im Bereich einer hier interessierenden Beschickungsstation 40 des um eine vertikale Achse drehbaren Faltrevolvers 35 ist der Zuschnitt 20 so weit vorgefaltet, dass in Radialrichtung gesehen eine winkelförmige Zwischenfaltstellung gegeben ist. Die Rückwand 25 mit den anschliessenden Zuschnitteilen Deckelstirnwand 27 und Deckelvorderwand 28 erstreckt sich in horizontaler Ebene, wobei die Rückwand 25 auf dem entsprechend bemessenen Taschenboden 37 aufliegt, während die daran anschliessenden Zuschnitteile aussen in Radialrichtung über den Taschenboden 37 hinwegragen. Die mit der Rückwand 25 verbundenen Seitenlappen 24 sind in eine aufrechte bzw. schräge Stellung gefaltet unter Anlage an der Innenseite der Taschenseitenwände 39. Diese sind mit geneigten, nämlich nach oben divergierenden Anlageflächen 41 ausgebildet, derart, dass die an diesen anliegenden Seitenlappen 24 ebenfalls schräg gerichtet sind, so dass eine in dieser Faltstellung nach oben weisende Seitenlappenkante 42 einen Abstand von dem in die Packung bzw. in die Packungstasche 36 eingeführten Zigaretten-Block 34 einnimmt.In the area of a loading station 40 of interest here of the folding turret 35, which can be rotated about a vertical axis, the blank 20 is pre-folded to such an extent that, seen in the radial direction, there is an angular intermediate folding position. The rear wall 25 with the adjoining cut parts, lid end wall 27 and lid front wall 28, extends in a horizontal plane, the rear wall 25 resting on the appropriately dimensioned pocket bottom 37, while the adjoining blank parts protrude radially beyond the pocket bottom 37. The side tabs 24 connected to the rear wall 25 are folded into an upright or inclined position, bearing against the inside of the pocket side walls 39. These are formed with inclined, namely upwardly diverging contact surfaces 41 such that the side tabs 24 lying against them are also inclined are directed so that a side tab edge 42 pointing upward in this folded position is at a distance from the cigarette block 34 inserted into the pack or into the pack pocket 36.

Die auf der radial aussen liegenden Seite auf die Seitenlappen 24 folgenden Zuschnitteile, nämlich der Innenzwickel 30 und der Deckelecklappen 31, die mit dem zugeordneten Seitenlappen 24 nicht verbunden sind, befinden sich in einer im wesentlichen aufrechten Position. Die an den Innenzwickel 30 anschliessenden Deckelecklappen 31 sind jedoch - im Grundriss gesehen - trichterförmig nach aussen gefaltet, um die Einführung des Zigaretten-Blocks 34 zu erleichtern.The cut parts following on the radially outer side of the side tabs 24, näm Lich the inner gusset 30 and the lid corner tab 31, which are not connected to the associated side tab 24, are in a substantially upright position. However, the lid corner flaps 31 adjoining the inner gusset 30 are - as seen in the plan - folded outwards in a funnel shape in order to facilitate the introduction of the cigarette block 34.

Ein aufrechter Schenkel des winkelförmig gefalteten Zuschnitts 20 wird durch die Bodenwand 22 und die anschliessende Vorderwand 23 gebildet. Die zu dieser gehörenden Seitenlappen 26 sind ebenfalls aufgerichtet und erstrecken sich in der Ebene der Vorderwand 23.An upright leg of the angularly folded blank 20 is formed by the bottom wall 22 and the adjoining front wall 23. The side tabs 26 belonging to this are also erected and extend in the plane of the front wall 23.

Während der radial gerichteten Einführung des Zigaretten-Blocks 34 in die in der beschriebenen Weise bereitgehaltene Packung bzw. den Zuschnitt 20 wird dieser in der Packungstasche 36 (zeitweilig) fixiert. Gegen unerwünschte Verschiebungen des Zuschnitts 20 in Radialrichtung sind seitliche Haltebacken 43 jeder Packungstasche 36 zugeordnet. Diese sind an den Enden eines zweiarmigen Schwenkhebels 44 angeordnet und können in die besonders in Fig. und 5 gezeigte Position gebracht werden. In dieser liegen die Haltebacken 43 an den aufrechten Innenzwickeln 30 an. Eine schräg gerichtete Stützkante 45 der Haltebacken 43 kommt zur Anlage an der ebenfalls schräg liegenden Endkante 32 der Seitenlappen 24. Diese Anlage ist durch die Schräglage der Seitenlappen 24 gegeben. Eine Verschiebung des Zuschnitts 20 in Radialrichtung innerhalb der Pakkungstasche 36 ist dadurch ausgeschlossen.During the radially directed insertion of the cigarette block 34 into the pack or blank 20 provided in the manner described, it is (temporarily) fixed in the pack pocket 36. Lateral holding jaws 43 are assigned to each packing pocket 36 against undesired displacements of the blank 20 in the radial direction. These are arranged at the ends of a two-armed pivot lever 44 and can be brought into the position shown particularly in FIGS. 5 and 5. In this, the holding jaws 43 rest on the upright inner gussets 30. An obliquely directed support edge 45 of the holding jaws 43 comes to rest on the likewise oblique end edge 32 of the side tabs 24. This contact is given by the inclined position of the side tabs 24. A displacement of the blank 20 in the radial direction within the packaging pocket 36 is thereby excluded.

Unerwünschte Aufwärtsbewegungen werden (zeitweilig) durch Niederhalter 46 verhindert, die von oben her auf die Packungstasche 36 bzw. den Zuschnitt 20 abgesenkt werden, derart, dass ein nach unten weisender Druckschenkel 47 auf dem Seitenlappen 24, nämlich der oberen Seitenlappenkante 42 aufliegt.Unwanted upward movements are prevented (temporarily) by holding-down devices 46, which are lowered from above onto the packing pocket 36 or the blank 20, such that a downward-pointing pressure leg 47 rests on the side tab 24, namely the upper side tab edge 42.

Die trichterförmige Position der Deckelecklappen 31 wird (zeitweilig) durch in eine entsprechende Position bewegbare Führungswände 48 gewährleistet, die im vorliegenden Fall mit dem Niederhalter 46 jeweils ein gemeinsames Organ bilden. Die Führungswände 48 sind jeweils an seitlichen Schwenkhebeln 49 angebracht und so ausgebildet, dass der Deckelecklappen 31 an entsprechend liegenden, schräg zur Transportrichtung des Zigaretten-Blocks 34 sich erstreckenden Stützflächen 50 Anlage erhält. Durch Bewegung der Schwenkhebel 49 wird die Führungswand 48 in Position gebracht, wobei infolge der keilförmigen Gestaltung der Führungswand 48 im Bereich der Stützfläche 50 der Deckelecklappen 31 gegenüber dem durch den Haltebacken 43 gehaltenen Innenzwickel 30 in die schräge Stellung gefaltet wird.The funnel-shaped position of the lid corner flaps 31 is (temporarily) ensured by guide walls 48 which can be moved into a corresponding position and which, in the present case, form a common organ with the hold-down device 46. The guide walls 48 are each attached to lateral pivot levers 49 and are designed such that the cover corner flap 31 is supported on correspondingly lying support surfaces 50 which extend obliquely to the transport direction of the cigarette block 34. The guide wall 48 is brought into position by movement of the pivoting lever 49, the wedge-shaped design of the guide wall 48 in the region of the supporting surface 50 of the lid corner flaps 31 folding the oblique position relative to the inner gusset 30 held by the holding jaws 43.

Schliesslich ist im Bereich der Beschickungsstation 40 dafür Sorge getragen, dass der in den Zuschnitt 20 eingeführte Zigaretten-Block 34 in einer exakten Stellung positioniert wird. Zu diesem Zweck ist von oben her eine Stempelplatte 51 zustellbar, die sich auf die Oberseite des Zigaretten-Blocks 34 auflegt und mit einer Abkantung 52 eine radial aussen liegende Stirnfläche 53 des Zigaretten-Blocks 34 erfasst.Finally, care is taken in the area of the loading station 40 that the cigarette block 34 inserted into the blank 20 is positioned in an exact position. For this purpose, a stamp plate 51 can be delivered from above, which lies on top of the cigarette block 34 and, with a bevel 52, detects a radially outer end face 53 of the cigarette block 34.

Die Zigaretten-Blöcke 34 werden im Sinne der Vorrichtung gemäss DE-OS 2440006 in Radialrichtung zum Faltrevolver 35 diesem zugefördert. Während der hier interessierenden Endphase des Transports wird der eine Gruppe von Zigaretten einhüllende Stanniol-Zuschnitt 33 im Bereich der in Transportrichtung rückseitigen Stirnfläche 53 fertiggefaltet.The cigarette blocks 34 are fed in the sense of the device according to DE-OS 2440006 in the radial direction to the folding turret 35. During the final phase of transport that is of interest here, the tinfoil blank 33 enveloping a group of cigarettes is finished in the region of the end face 53 on the back in the transport direction.

Die Zigaretten-Blöcke 34 werden nacheinander auf einer Packungsbahn 54 durch einen Kettenförderer einer Blocktasche 55 zu- und in diese eingeführt. Die Blocktasche 55 übernimmt den Transport des Zigaretten-Blocks 34 bis in die Nähe des Faltrevolvers 35. Die Blocktasche 55 ist zu diesem Zweck hin- und herbewegbar. Bei dem vorliegenden Ausführungsbeispiel ist die Blocktasche 55 auf einer quer zur Bewegungsrichtung sich erstreckenden plattenförmigen Traverse 56 gebildet. Diese wiederum ist auf seitlichen Führungsstangen 57 gelagert und gleitend verschiebbar.The cigarette blocks 34 are successively fed to and inserted into a block pocket 55 on a packing track 54 by a chain conveyor. The block pocket 55 takes over the transport of the cigarette block 34 into the vicinity of the folding turret 35. The block pocket 55 can be moved back and forth for this purpose. In the present exemplary embodiment, the block pocket 55 is formed on a plate-shaped cross member 56 which extends transversely to the direction of movement. This in turn is mounted on side guide rods 57 and slidably.

Die Blocktasche 55 besteht aus einem Boden 58, aufrechten Seitenwänden 59 und einer Oberwand 60. Letztere wird durch zwei (horizontale) Schenkel 61, 62 gebildet, zwischen denen ein etwas aussermittig verlaufender Schlitz 63 gebildet ist. Die Rückseite zum Einführen des Zigaretten- Blocks 34 und die Vorderseite für den Ausschub desselben sind offen.The block pocket 55 consists of a base 58, upright side walls 59 and an upper wall 60. The latter is formed by two (horizontal) legs 61, 62, between which a slightly eccentric slot 63 is formed. The back for inserting the cigarette block 34 and the front for ejecting it are open.

Der Boden 58 der Blocktasche 55 besteht aus zwei Teilen, nämlich einem hier in Transportrichtung vorn liegenden Festteil 64 und einem etwa die rückwärtige Hälfte des Bodens 58 bildenden Hubteil 65. Letzterer ist nach dem Einführen eines Zigaretten-Blocks 34 in die Blocktasche 55 anhebbar, derart, dass der Zigaretten-Block 34 mit angehoben und dadurch an der Oberwand 60 der Blocktasche 55 durch Andrücken fixiert wird. Dadurch wird der Zigaretten-Block 34 während des Transports durch die Blocktasche 55 in dieser gegen Relativbewegungen fixiert.The bottom 58 of the block pocket 55 consists of two parts, namely a fixed part 64 located here at the front in the transport direction and a lifting part 65 which forms approximately the rear half of the bottom 58. The latter can be lifted after inserting a cigarette block 34 into the block pocket 55, such that the cigarette block 34 is also lifted and thereby fixed to the top wall 60 of the block pocket 55 by pressing. As a result, the cigarette block 34 is fixed in the block pocket 55 during transport against relative movements.

Der bewegbare Teil des Bodens 58, also der Hubteil 65, ist bei dem vorliegenden Ausführungsbeispiel an einem (zweiarmigen) Druckhebel 66 angeordnet. Dieser um ein Lager 67 schwenkbare Druckhebel 66 ist mit dem freien Ende über eine Tastrolle 68 auf einer Führungsbahn in Gestalt einer Stützschiene 69 abstützbar. Die sich in horizontaler Ebene erstreckende Stützschiene 69 ist heb- und senkbar, im vorliegenden Fall durch ein Parallelogrammgestänge 70. Die Anordnung ist hier so getroffen, dass das Hubteil 65 bzw. der Druckhebel 66 durch eine Druckfeder 71 vorgespannt sind, und zwar in Richtung auf Anheben und Festklemmen des Zigaretten-Blocks 34. Gegen diese Belastung durch die Druckfeder 71 ist der Druckhebel 66 durch Anheben der Stützschiene 69 im Uhrzeigersinn schwenkbar, wodurch das Hubteil 65 abgesenkt wird und der Zigaretten-Block 34 aus der Klemmstellung freikommt. Die Stützschiene 69 wird demnach jeweils an den Endstellungen der Blocktasche 55 angehoben.The movable part of the base 58, that is to say the lifting part 65, is arranged on a (two-armed) pressure lever 66 in the present exemplary embodiment. This pressure lever 66, which can be pivoted about a bearing 67, can be supported with the free end via a feeler roller 68 on a guideway in the form of a support rail 69. The support rail 69, which extends in the horizontal plane, can be raised and lowered, in the present case by means of a parallelogram linkage 70. The arrangement here is such that the lifting part 65 or the pressure lever 66 are prestressed by a compression spring 71, specifically in the direction of Lifting and clamping the cigarette block 34. Against this load by the compression spring 71, the pressure lever 66 can be pivoted clockwise by lifting the support rail 69, as a result of which the lifting part 65 is lowered and the cigarette block 34 is released from the clamping position. The support rail 69 is accordingly raised at the end positions of the block pocket 55.

An der Blocktasche 55 ist weiterhin ein Unterfalter 72 in Gestalt eines schwenkbaren Hebels angeordnet. Dieser wird nach Einführung des Zigaretten-Blocks 34 in die Blocktasche 55 in faltendem Sinne verschwenkt, und zwar etwa in die Position gemäss Fig. 6. Dabei wird ein unterer, nach rückwärts gerichteter Stirnlappen 73 des Stanniol-Zuschnitts 33 in die Ebene der rückseitigen Stirnfläche 53 gefaltet. Der Unterfalter 72 und der Druckhebel 66 sind im vorliegenden Fall gleichachsig gelagert, nämlich auf einer quer gerichteten Achse 74 angeordnet, die in Tragschenkein 75 an der Unterseite der Traverse 56 gelagert ist.At the block pocket 55 there is also an underfold 72 in the form of a pivotable lever orderly. After the cigarette block 34 has been introduced into the block pocket 55, it is pivoted in a folding sense, approximately into the position shown in FIG 53 folded. The lower folder 72 and the pressure lever 66 are mounted coaxially in the present case, namely arranged on a transverse axis 74, which is mounted in support legs 75 on the underside of the cross member 56.

Durch formschlüssiges Ankuppeln ist gewährleistet, dass die Blocktasche 55 in der der Pakkungsbahn 54 zugekehrten Ausgangsstellung stets in einer exakten Relativstellung zu dieser gehalten ist, um ein einwandfreies Einführen des Zigaretten-Blocks 34 in die Blocktasche 55 sicherzustellen. Zu diesem Zweck sind an der Packungsbahn 54 Bodenzungen 76 und Seitenzungen 77 angeordnet. Diese vorstehenden Führungsteile treten in der entsprechenden Position der Blocktasche 55 formschlüssig in Ausnehmungen derselben ein. Zu diesem Zweck sind der Boden 58 und die Seitenwände 59 mit zur Rückseite offenen Ausnehmungen 78 und 79 für den Eintritt der Bodenzungen 76 einerseits und der Seitenzungen 77 andererseits versehen. Die Seitenzungen 77 sind dabei als Fortsetzung einer Seitenbegrenzung 80 der Packungsbahn 54 ausgebildet, während die Bodenzungen 76 an die plattenförmige Packungsbahn 54 anschliessen.A form-fitting coupling ensures that the block pocket 55 is always held in an exact relative position in the starting position facing the packing path 54, in order to ensure a correct insertion of the cigarette block 34 into the block pocket 55. For this purpose, bottom tongues 76 and side tongues 77 are arranged on the packing track 54. In the corresponding position of the block pocket 55, these protruding guide parts form-fit into recesses in the same. For this purpose, the bottom 58 and the side walls 59 are provided with recesses 78 and 79 open to the rear for the entry of the bottom tongues 76 on the one hand and the side tongues 77 on the other hand. The side tongues 77 are designed as a continuation of a side boundary 80 of the packing web 54, while the bottom tongues 76 connect to the plate-shaped packing web 54.

Der Zigaretten-Block 34 wird durch die Blocktasche 55 - wie bei der Vorrichtung gemäss DE-OS 2 440 006 - bis in einen mit Abstand vor dem Faltrevolver 35 liegenden Bereich gefördert. Während die Blocktasche 55 durch gegenläufige Bewegung wieder in die Ausgangsposition zurückgeführt wird, tritt ein Ausschieber 81 in Aktion, der oberhalb der Bewegungsbahn der Blocktasche 55 angeordnet ist und eine komplexe Auf- und Abbewegung sowie eine Bewegung in Transportrichtung des Zigaretten-Blocks 34 ausführt.The cigarette block 34 is conveyed through the block pocket 55 - as in the device according to DE-OS 2 440 006 - into a region lying at a distance in front of the folding turret 35. While the block pocket 55 is returned to the starting position by counter-movement, an ejector 81 comes into action, which is arranged above the path of movement of the block pocket 55 and performs a complex up and down movement and a movement in the transport direction of the cigarette block 34.

Der Ausschieber 81 hat eine Mehrfachfunktion. Winkelstück 82 dient als Oberfalter. Bei der Abwärtsbewegung des Ausschiebers 81 zum Erfassen des Zigaretten-Blocks 34 an der rückseitigen Stirnfläche 53 wird ein oberer, nach rückwärts gerichteter Stirnlappen 83 in die Ebene der Stirnfläche 53 umgefaltet. Zuvor sind bereits Seitenlappen des Stanniol-Zuschnitts 33 ebenfalls in die Ebene der Stirnfläche 53 gefaltet worden, und zwar durch im einzelnen hier nicht dargestellte, jedoch der Vorrichtung gemäss DE-OS 2 440 006 entsprechende Seitenfalter, die mit an der Blocktasche 55 angeordnet sind.The pusher 81 has a multiple function. Angle piece 82 serves as an upper butterfly. During the downward movement of the ejector 81 for gripping the cigarette block 34 on the rear end face 53, an upper, rearward-facing end tab 83 is folded over into the plane of the end face 53. Previously, side tabs of the tinfoil blank 33 had also been folded into the plane of the end face 53, specifically by side folders not shown here but corresponding to the device according to DE-OS 2 440 006, which are also arranged on the block pocket 55.

Der in der dem Faltrevolver 35 zugekehrten Endstellung der Blocktasche 55 - etwa die mit strichpunktierten Linien dargestellte Position in Fig. 5 - aus der Blocktasche 55 durch den Ausschieber 81 herausgeförderte Zigaretten-Block 34 wird anschliessend durch ein Übergabeorgan übernommen, welches dem Mundstück 116 der Vorrichtung gemäss DE-OS 2 440 006 entspricht. Die bereits beschriebenen Führungswände 48 sind Teil dieses Mundstücks. Der Zigaretten-Block 34 wird durch den Ausschieber 81 bis in die Endstellung innerhalb der Packung bzw. innerhalb des Zuschnitts 20 gefördert. Die Führungswände 48 bzw. das aus diesen gebildete Mundstück 84 vollführt dabei eine Schwenkbewegung, wobei die an diesem Mundstück 84 bzw. an den Führungswänden 48 angeordneten Niederhalter 46 in die Arbeitsstellung bewegt werden. Diese Schwenkbewegung führt auch dazu, dass die Deckelecklappen 31 in die trichterförmige Position gelangen, die sich im Detail aus Fig. 11 ergibt. Zuvor sind bereits die Haltebacken 43 in Position gebracht worden. Nach dem Einschub des Zigaretten-Blocks 34 wird die Stempelplatte 51 in die bereits beschriebene Justierstellung abgesenkt.The cigarette block 34 conveyed out of the block pocket 55 by the ejector 81 in the end position of the block pocket 55 facing the folding turret 35 - approximately the position shown in dash-dotted lines in FIG. 5 - is then taken over by a transfer device which is attached to the mouthpiece 116 of the device corresponds to DE-OS 2 440 006. The guide walls 48 already described are part of this mouthpiece. The cigarette block 34 is conveyed by the pusher 81 to the end position within the pack or within the blank 20. The guide walls 48 or the mouthpiece 84 formed therefrom performs a pivoting movement, the hold-down devices 46 arranged on this mouthpiece 84 or on the guide walls 48 being moved into the working position. This pivoting movement also leads to the lid corner flaps 31 reaching the funnel-shaped position which results in detail from FIG. 11. The holding jaws 43 have already been brought into position beforehand. After inserting the cigarette block 34, the stamp plate 51 is lowered into the adjustment position already described.

Die weiteren Faltschritte für den Zuschnitt 20 können in der in der DE-OS 2 440 006 beschriebenen Weise vonstatten gehen.The further folding steps for the blank 20 can take place in the manner described in DE-OS 2 440 006.

Die hier vorrangig angesprochenen Packungen des Typs «Klappschachtel» sind überwiegend mit einem Kragen ausgestattet, der von einem gesonderten Kragenzuschnitt 85 gebildet wird. Dieser muss dem Zigaretten-Block 34 zugefördert und vor der Fertigstellung der Packung in geeigneter Weise mit dieser vereinigt werden, derart, dass sich der Kragen im Bereich der Vorderwand 23 sowie der durch die Seitenlappen 24 und 26 gebildeten Seitenwände erstreckt.The packs of the “hinged box” type that are primarily addressed here are predominantly equipped with a collar which is formed by a separate collar cut 85. This must be conveyed to the cigarette block 34 and combined with it in a suitable manner before the pack is completed, such that the collar extends in the region of the front wall 23 and the side walls formed by the side tabs 24 and 26.

Die Kragenzuschnitte 85 werden zu diesem Zweck quer zur Förderrichtung des Zigaretten- Blocks 34 zugefördert und danach parallel und synchron dazu bis zur Einführung in die Packung bzw. den Zuschnitt 20 transportiert. Die Vereinigung erfolgt erst innerhalb der Packungstasche 36 des Faltrevolvers 35.For this purpose, the collar blanks 85 are fed in transversely to the conveying direction of the cigarette block 34 and then transported in parallel and in synchronism therewith until they are introduced into the pack or the blank 20. The union takes place only within the packing pocket 36 of the folding turret 35.

Die Einführung der Kragenzuschnitte 85 in die radiale Bewegungsbahn des Zigaretten-Blocks 34 erfolgt im Bereich der rückwärtigen Endstellung der Blocktasche 55. Die Kragenzuschnitte 85 werden dieser Station aufeinanderfolgend durch einen Kragenförderer 86 zugeführt. Es handelt sich dabei um einen besonders leichten bzw. massearmen Zahnriemen aus Kunststoff. Auf der Aussenseite desselben sind im Abstand voneinander Mitnehmernasen 87 angebracht, die jeweils einen Kragenzuschnitt an der Seite erfassen, nämlich im Bereich einer der Kragenseitenwände 88. Die Kragen werden demnach durch den Kragenförderer 86 in der dem Weitertransport entsprechenden Relativstellung transportiert.The collar cuts 85 are introduced into the radial movement path of the cigarette block 34 in the area of the rear end position of the block pocket 55. The collar cuts 85 are fed to this station in succession by a collar conveyor 86. It is a particularly light or low-mass toothed belt made of plastic. On the outside thereof, driver lugs 87 are attached at a distance from one another, each of which grips a collar cut on the side, namely in the region of one of the collar side walls 88. The collars are accordingly transported by the collar conveyor 86 in the relative position corresponding to the further transport.

Die Anordnung im Bereich des Kragenförderers 86 ist so getroffen, dass ein Untertrum 89 den Transport besorgt, wobei die Kragenzuschnitte 85 ausserhalb des Bereichs des Kragenförderers 86 in bzw. auf einer feststehenden Transportbahn 90 aufliegend gefördert werden. Diese ist im wesentlichen als feststehende Platte ausgebildet mit seitlichen Führungsschlitzen 91 für den Eintritt seitlicher Bereiche des Kragenzuschnitts 85 und mit einer etwa mittigen Vertiefung 92 für den Eintritt des Kragenförderers 86. Die Kragenzuschnitte 85 werden dem Kragenförderer 86 quer zu dessen Transportrichtung durch Förderwalzen 93 zugeführt.The arrangement in the area of the collar conveyor 86 is such that a lower strand 89 takes care of the transport, the collar cuts 85 being conveyed lying outside the area of the collar conveyor 86 in or on a fixed transport path 90. This is essentially designed as a fixed plate with lateral guide slots 91 for the entry of lateral areas of the collar cut 85 and with an approximately central recess 92 for the entry of the collar conveyor 86. The collar cuts 85 are fed to the collar conveyor 86 transversely to its transport direction by conveyor rollers 93.

Die Kragenzuschnitte 85 werden durch den Kragenförderer 86 jeweils auf der Oberseite der Blocktasche 55 abgelegt, wenn sich diese in der packungsfernen Ausgangsstellung befindet. Zur Aufnahme des Kragenzuschnitts 85 ist oberhalb der Blocktasche 55, nämlich mit geringem Abstand über der Oberwand 60, eine Kragentragplatte 94 ortsfest angeordnet. Diese erstreckt sich zwischen seitlichen Mitnehmervorsprüngen 95 auf der Oberwand 60 der Blocktasche 55 und im rückwärtigen Bereich derselben. Die vorgenannten Mitnehmervorsprünge 95 erfassen den Kragenzuschnitt 85 während des Transportes durch die Blocktasche 55 an der Rückseite.The collar blanks 85 are each deposited on the top of the block pocket 55 by the collar conveyor 86 when the latter is in the initial position remote from the pack. To receive the collar blank 85, a collar support plate 94 is arranged in a stationary manner above the block pocket 55, namely at a short distance above the upper wall 60. This extends between lateral driver projections 95 on the top wall 60 of the block pocket 55 and in the rear region thereof. The aforementioned driver projections 95 capture the collar blank 85 during transport through the block pocket 55 on the back.

Um die Einführung des Kragenzuschnitts 85 in die Bewegungsbahn der Blocktasche 55 zu ermöglichen, ist die Transportbahn 90 für den Kragenzuschnitt 85 mit einem plattenförmigen Verlängerungsstück 96 versehen, welches auf der zum Kragenförderer 86 gegenüberliegenden Seite in bezug auf die Blocktasche 55 einen Anschlag zur Positionierung des Kragenzuschnitts 85 bildet, und zwar innerhalb eines Anschlagschlitzes 97.In order to enable the introduction of the collar blank 85 into the path of movement of the block pocket 55, the transport path 90 for the collar blank 85 is provided with a plate-shaped extension piece 96 which, on the side opposite the collar conveyor 86 with respect to the block pocket 55, has a stop for positioning the collar blank 85 forms, namely within a stop slot 97.

Um den Kragenzuschnitt 85 während dieser Änderung der Bewegungsrichtung exakt auf der Kragentragplatte 94 zu fixieren, ist ein Niederhalter 98 oberhalb der Kragentragplatte 94 angeordnet. Dieser besteht aus einem Federblech mit einer an der Oberseite des Kragenzuschnitts 85 federnd anliegenden Andrücknase 99. Der Niederhalter 98 ist ortsfest gelagert. Der Kragenzuschnitt 85 wird bei der Zuführung durch den Kragenförderer 85 unter die Andrücknase 99 geschoben und bei der Weiterförderung aus dieser Halteposition herausgezogen, wenn der Kragenzuschnitt 85 durch die Mitnehmervorsprünge 95 der Blocktasche 55 mitgenommen wird. An der Unterseite der Kragentragplatte 94 ist ein länglicher Nocken 100 angeordnet, der in der Ausgangsstellung in den zwischen den Schenkeln 61 und 62 der Oberwand 60 der Blocktasche 55 gebildeten Schlitz 63 ragt und im wesentlichen mit der Unterseite der Oberwand 60 bündig abschliesst.In order to fix the collar blank 85 exactly on the collar support plate 94 during this change in the direction of movement, a hold-down device 98 is arranged above the collar support plate 94. This consists of a spring plate with a pressing nose 99 resiliently resting on the upper side of the collar blank 85. The hold-down device 98 is mounted in a stationary manner. The collar blank 85 is pushed under the pressing nose 99 during the feeding by the collar conveyor 85 and pulled out of this holding position during the further conveying if the collar blank 85 is taken along by the driver projections 95 of the block pocket 55. On the underside of the collar support plate 94 there is an elongated cam 100 which, in the starting position, projects into the slot 63 formed between the legs 61 and 62 of the top wall 60 of the block pocket 55 and is essentially flush with the underside of the top wall 60.

Der Kragenzuschnitt 85 wird während des Weitertransports durch die Blocktasche 55 mit Abstand oberhalb der Oberwand 60 derselben gefördert. Zu diesem Zweck schliesst an das Verlängerungsstück 96 bzw. an den Anschlagschlitz 97 beidseitig eine Führungsbahn 101 für den Kragen- zuschnitt 85 an. Sie besteht aus langgestreckten Führungsschienen 102 und 103, zwischen denen ein Führungsschlitz 104 für den Eintritt der seitlichen Teile (Kragenseitenwände 88) des Kragen- zuschnitts 85 gebildet ist.The collar blank 85 is conveyed through the block pocket 55 at a distance above the top wall 60 thereof during further transport. For this purpose, a guide track 101 for the collar blank 85 adjoins the extension piece 96 or the stop slot 97 on both sides. It consists of elongated guide rails 102 and 103, between which a guide slot 104 is formed for the entry of the lateral parts (collar side walls 88) of the collar blank 85.

Der Kragenzuschnitt 85 wird erst unmittelbar im Bereich der Packungstasche 36 des Faltrevolvers 35 aus der Führungsbahn 101 herausgefördert, und zwar unter Absenken auf den sich darunter befindenden Zigaretten-Block 34. Während dieser Übergabephase vollziehen sich mehrere Bearbeitungsvorgänge. Durch die seitlichen Führungswände 48 bzw. durch an diesen angeordnete, besonders geformte (bogenförmige) Faltkanten 105 werden die Kragenseitenwände 88 infolge der Relativbewegung des Kragenzuschnitts 85 gegenüber den Führungswänden 48 nach unten umgefaltet. Dieses Umfalten der Kragenseitenwände 88 vollzieht sich während einer Phase, in der der Kragenzuschnitt 85 noch in der Führungsbahn 101 gehalten wird. Die Kragenseitenwände 88 werden dabei um die untere Führungsschiene 103 gefaltet (Fig. 10). Die Führungswände 48 werden dabei in schwenkendem Sinne bewegt und dienen als Faltorgan. Der Kragenzuschnitt 85 wird demnach mit nach unten gefalteten Kragenseitenwänden 88 aus der Führungsbahn 101 herausgefördert und auf den Zigaretten-Block 34 innerhalb des Zuschnitts 20 abgesenkt.The collar blank 85 is only conveyed out of the guideway 101 directly in the area of the packing pocket 36 of the folding turret 35, specifically by lowering it onto the cigarette block 34 located underneath. During this transfer phase, several processing operations take place. Due to the lateral guide walls 48 or by means of specially shaped (arc-shaped) folded edges 105 arranged thereon, the collar side walls 88 are folded downward as a result of the relative movement of the collar blank 85 relative to the guide walls 48. This folding over of the collar side walls 88 takes place during a phase in which the collar blank 85 is still held in the guideway 101. The collar side walls 88 are folded around the lower guide rail 103 (FIG. 10). The guide walls 48 are moved in a pivoting sense and serve as a folding member. The collar blank 85 is accordingly conveyed out of the guideway 101 with the collar side walls 88 folded down and lowered onto the cigarette block 34 within the blank 20.

Zugleich wird der Kragenzuschnitt 85 hinsichtlich der exakten Relativstellung in bezug auf den Zigaretten-Block 34 justiert, und zwar durch Anlage des Kragenzuschnitts 85 an einem mit dem Ausschieber 81 verbundenen Justierstück 106. Dieses befindet sich während der Übergabe des Kragenzuschnitts 85 an dem Zigaretten-Block 34 unmittelbar und mit geringem Abstand oberhalb desselben. Durch den Ausschub des Zigaretten- Blocks 34 aus der Blocktasche 55 durch den Ausschieber 81 wird auch der Kragenzuschnitt 85 weitertransportiert, und zwar durch ein am vorderen Ende des Ausschiebers 81 angeordnetes Justierstück 106. Dieses hat zugleich die Funktion, die exakte Relativstellung des Kragenzuschnitts 85 in bezug auf den Zigaretten-Block 34 zu bestimmen, bevor der Kragenzuschnitt 85 auf diesem abgelegt wird. Das Justierstück 106 erhält dabei Anlage an einer während des Transports nach rückwärts weisenden Kante des Kragenzuschnitts 85 innerhalb einer Kragenausnehmung 107. Der Abstand zwischen dem Justierstück 106 und dem Winkelstück 82 als eigentliches Schuborgan für den Zigaretten-Block 34 entspricht demnach der Relativstellung zwischen Kragenzuschnitt 85 und Zigaretten-Block 34.At the same time, the collar cut 85 is adjusted with regard to the exact relative position with respect to the cigarette block 34, namely by the collar cut 85 resting on an adjustment piece 106 connected to the ejector 81. This is located during the transfer of the collar cut 85 to the cigarette block 34 immediately and at a short distance above it. By pushing the cigarette block 34 out of the block pocket 55 through the pusher 81, the collar blank 85 is also transported further, namely by an adjusting piece 106 arranged at the front end of the pusher 81. At the same time, this function has the function of the exact relative position of the collar blank 85 in to determine with respect to the cigarette block 34 before the collar blank 85 is placed thereon. The adjusting piece 106 is in contact with an edge of the collar cut 85 facing backwards during transport within a collar recess 107. The distance between the adjusting piece 106 and the angle piece 82 as the actual thrust member for the cigarette block 34 therefore corresponds to the relative position between the collar cut 85 and Cigarette block 34.

Nach dem bereits beschriebenen Arbeitstakt der Stempelplatte 51 gehen die weiteren Faltschritte für die Packung in bekannter Weise vonstatten, insbesondere im Sinne der DE-OS 2 440 006.After the work cycle of the stamp plate 51 already described, the further folding steps for the pack take place in a known manner, in particular in the sense of DE-OS 2 440 006.
