Es geht um die Behandlung von quaderförmigen Packungen 10, und zwar insbesondere von Zigarettenpackungen des Typs Klappschachtel. Es handelt sich dabei um eine üblicherweise aus dünnem Karton bestehende Klappschachtel mit Packungsflächen bzw. -seiten unterschiedlicher Abmessungen, nämlich mit großflächiger Vorderseite 11 und Rückseite 12, schmalen Seitenflächen 13, 14 und Stirn- sowie Bodenflächen 15, 16.It is about the treatment of cuboidal packs 10, in particular cigarette packs of the folding box type. It is a folding carton, usually consisting of thin cardboard, with packing surfaces or sides of different dimensions, namely with a large front side 11 and rear side 12, narrow side surfaces 13, 14 and front and bottom surfaces 15, 16.

Die Packung 10 ist von einer Außenumhüllung aus Folie 17 umgeben, die vorzugsweise an allen Pakkungsflächen anliegt. Die Folie 17 weist Faltungen im Bereich der Stirn- und Bodenfläche 15, 16 sowie im Bereich einer Seitenfläche 13 auf. Die Faltlappen sind durch thermisches Siegeln miteinander verbunden. Die Folie 17 besteht aus thermisch schrumpfbarem Material. Zu diesem Zweck werden die mit der Außenumhüllung, nämlich mit der Folie 17 versehenen Packungen 10 einem Schrumpfaggregat zugeführt, und zwar einem vorzugsweise kontinuierlich drehenden Schrumpfrevolver 19. Die komplett fertiggestellten Packungen 10 werden dem Schrumpfrevolver 19 von einem ebenfalls vorzugsweise kontinuierlich angetriebenen Förderer zugeführt, insbesondere von einem Siegelrevolver 20 zum thermischen Siegeln der Faltlappen der Folie 17. Der Schrumpfrevolver 19 ist mit einer Mehrzahl von längs des Umfangs verteilten Taschen bzw. Aufnahmen 21 versehen für je eine Packung 10. Die Packungen 10 sind in den Aufnahmen 21 mit ihrerLängserstreckung in achsparalleler Richtung positioniert. Die großen Packungsflächen, nämlich Vorderseite 11 und Rückseite 12, sind annähernd radial gerichtet, in Förderrichtung vorn oder rückseitig, die Seitenflächen 13,14 demnach radial innen bzw. außen liegend.The package 10 is surrounded by an outer envelope of film 17, which preferably rests against all Pakkungsflächen. The film 17 has folds in the region of the front and bottom surface 15, 16 and in the region of a side surface 13. The folding flaps are connected by thermal sealing. The film 17 is made of thermally shrinkable material. For this purpose, the packs 10 provided with the outer wrapper, namely with the film 17, are fed to a shrinkage aggregate, namely a shrinking revolver 19 which preferably rotates continuously. The completely finished packs 10 are fed to the shrinking revolver 19 by a likewise preferably continuously driven conveyor, in particular a sealing turret 20 for thermal Sealing the folding tabs of the film 17. The shrinking turret 19 is provided with a plurality of distributed along the circumference of pockets or receptacles 21 for each pack 10. The packs 10 are positioned in the receptacles 21 with their longitudinal extension in the axis-parallel direction. The large packing surfaces, namely front side 11 and rear side 12, are directed approximately radially, in the conveying direction at the front or rear side, the side surfaces 13, 14 accordingly lying radially inwards or outwards.

Im Bereich einer Aufnahme 21 wird die Pakkung 10 während des Transports durch den Schrumpfrevolver 19 einer Wärmebehandlung unterzogen. Dabei wird Wärme auf die großflächigen Packungsseiten, also auf Vorderseite 11 und Rückseite 12, übertragen. Wärmeorgane sind als Wärmeplatten 22, 23 ausgebildet. Diese liegen mit einer vorzugsweise elastischen Heizauflage 24 an Vorderseite 11 und Rückseite 12 an. Die Wärmeplatten 22,23 sind so bemessen, dass die betreffenden Packungsseiten vollflächig abgedecktsind. Jeder Aufnahme sind zwei gemeinsam, gleichzeitig bewegbare Wärmeplatten 22, 23 zugeordnet.In the region of a receptacle 21, the package 10 is subjected during the transport through the shrinking turret 19 to a heat treatment. In this case, heat is transferred to the large-area sides of the package, that is, on the front 11 and back 12. Heat elements are designed as heat plates 22, 23. These lie with a preferably elastic heating pad 24 on the front 11 and 12 back. The heat plates 22,23 are dimensioned so that the relevant package pages are covered over the entire surface. Each recording is associated with two common, simultaneously movable heat plates 22, 23.

Die Wärmeplatten 22, 23 sind quer zu den Pakkungen 10 bzw. den zu beaufschlagenden Packungsseiten 11, 12 bewegbar. Jede Wärmeplatte 22, 23 ist an einem Schwenkhebel 25, 26 angebracht. Die Kinematik für die Wärmeplatten 22, 23 ist aufgrund der Ausgestaltung, Bemessung und Lagerung der Schwenkhebel 25, 26 so gewählt, dass jede Wärmeplatte 22, 23 in der Heizstellung vollflächig an der zugeordneten Packungsseite anliegt. Bei einer quaderförmigen Packung 10 sind demnach die Wärmeplatten 22, 23 in dieser Funktionsstellung parallel zueinander gerichtet. Für die Aufnahme und Freigabe einer Packung 10 werden die Wärmeplatten 22, 23 in eine nach außen divergierende Öffnungsstellung geschwenkt. Das Einführen der Packungen 10 in einer annähernden Radialrichtung ist dadurch erleichtert, ebenso die Entnahme der behandelten Packungen, insbesondere bei Übergabe an einen Abförderer27. Die unterschiedlich langen Schwenkhebel 25,26 sind mittels Schwenklager 40, 41 an dem Schrumpfrevolver 19 bzw. an einer Revolverscheibe gelagert. Die Schwenklager 40, 41 sind etwa auf einer gemeinsamen Radialebene gelagert, wobei der Schwenkhebel 25 winkelförmig und der kürzere Schwenkhebel 26 geradlinig ausgebildet ist.The heat plates 22, 23 are movable transversely to the packages 10 and the package sides 11, 12 to be charged. Each heat plate 22, 23 is attached to a pivot lever 25, 26. The kinematics for the heat plates 22, 23 is due to the design, dimensioning and storage of the pivot lever 25, 26 chosen so that each heat plate 22, 23 in the heating position over the entire surface of the associated pack side. In the case of a parallelepipedic packing 10, the heating plates 22, 23 are therefore directed parallel to one another in this functional position. For receiving and releasing a pack 10, the heat plates 22, 23 are pivoted into an outwardly diverging open position. The introduction of the packs 10 in an approximate radial direction is thereby facilitated, as is the removal of the treated packs, in particular when they are transferred to a discharge conveyor 27. The differently long pivot lever 25,26 are mounted by means of pivot bearings 40, 41 on the shrinking turret 19 and on a turret disc. The pivot bearings 40, 41 are mounted approximately on a common radial plane, wherein the pivot lever 25 is angular and the shorter pivot lever 26 is formed in a straight line.

Eine Besonderheit ist die Ausbildung der Aufnahme 21 zur Handhabung der Packungen 10. Jeder Aufnahme 21 sind bewegbare Halteorgane für die Pakkungen 10 zugeordnet, nämlich schwenkbare Haltebakken 28, 29. Diese sind unabhängig von den Wärmeplatten 22, 23 betätigbar und erfassen die Packung 10 an nicht durch die Wärmeplatten 22, 23 abgedeckten, quergerichteten Packungsseiten, hier im Bereich von Stirnfläche 15 und Bodenfläche 16. Die Haltebacken 28, 29 sind demnach in achsparalleler Richtung zwischen Haltestellung (Fig. 4, Fig. 5) und Öffnungsstellung (Fig. 6, Fig. 9) bewegbar.A special feature is the formation of the receptacle 21 for handling the packs 10. Each receptacle 21 are associated with movable holding members for the packages 10, namely pivotable Haltebakken 28, 29. These are independent of the heat plates 22, 23 actuated and detect the pack 10 at not by the heat plates 22, 23 covered, transverse pack sides, here in the region of the end face 15 and bottom surface 16. The holding jaws 28, 29 are therefore in the direction parallel to the axis between the holding position ( Fig. 4, Fig. 5 ) and open position ( Fig. 6 . Fig. 9 ) movable.

Die Haltebacken haben eine mehrfache Funktion, dienen nämlich auch zur Übernahme der Packungen 10 von dem Zuförderer bzw. dem Siegelrevolver 20, zur Positionierung der Packung 10 in der Aufnahme 21 und zur Überführung an den Abförderer 27. Die Haltebacken 28, 29 sind entsprechend bewegbar. Jeder Haltebacke 28, 29 zugeordnete Schwenkarme 30, 31 sind - schwenkbar - an einem Träger angebracht, der seinerseits bewegbar am Schrumpfrevolver 19 gelagert ist. Es handelt sich dabei um eine drehbare Tragstange 32, auf der die beiden Schwenkarme 30, 31 mit Haftemuffen in gleich gerichteter Relativstellung gelagert sind. Durch Drehen der Tragstange 32 werden die Tragstücke 33 entsprechend gedreht und mit diesen die Haltbacken 28. 29 über die Schwenkarme 30, 31.The holding jaws have a multiple function, namely serve to take over the packs 10 from the feed conveyor or the sealing turret 20, for positioning the pack 10 in the receptacle 21 and for transfer to the discharge conveyor 27. The holding jaws 28, 29 are movable accordingly. Each holding jaw 28, 29 associated pivot arms 30, 31 are - pivotally mounted on a support which in turn is movably mounted on the shrinking turret 19. It is a rotatable support rod 32, on which the two pivot arms 30, 31 are mounted with adhesive sleeves in the same direction relative position. By rotating the support rod 32, the support pieces 33 are rotated accordingly and with them the retaining jaws 28. 29 via the pivot arms 30, 31.

Aufgrund entsprechender Steuerung der Haltebacken 28, 29werden in eineroberen Aufnahmestation 34 die Packungen 10 im Bereich des Siegelrevolvers 20 erfasst und durch entsprechende Schwenkbewegung am Außenumfang des Schrumpfrevolvers 19 (außerhalb desselben) entlang bewegt. Unter Drehung der Packungen 10 um ihre Längachse werden diese schließlich von außen in den Bereich der Aufnahme 21 eingeführt und dort auf einem feststehenden Anlagestück 35 des Revolvers positioniert. Danach werden die Wärmeplatten 22, 23 in die Behandlungsposition unter Anlage an Vorderseite 11 und Rückseite 12 gefahren, wobei die Haltebacken 28, 29 in der Halterposition bleiben. Anschließend werden diese kurzzeitig zurückgeschwenkt (Fig. 6), damit sich die Packung 10 spannungsfrei auf die Wärmeplatten 22, 23 ausrichten können. Die Haltebakken 28, 29 kehren sodann in die Haltestellung zurück und bleiben in dieser während des Schrumpfprozesses.Due to appropriate control of the holding jaws 28, 29, the packs 10 in the region of the sealing turret 20 are detected in an upper receiving station 34 and moved along the outer circumference of the shrinking turret 19 (outside the same) by corresponding pivoting movement. When the packages 10 are rotated about their longitudinal axis, they are finally introduced from the outside into the region of the receptacle 21 and positioned there on a fixed contact piece 35 of the revolver. Thereafter, the heat plates 22, 23 are moved into the treatment position under contact with the front 11 and back 12, wherein the holding jaws 28, 29 remain in the holder position. These are then swung back briefly ( Fig. 6 ), so that the pack 10 can be aligned stress-free on the heat plates 22, 23. The Haltebakken 28, 29 then return to the holding position and remain in this during the shrinking process.

Die Packungen 10 werden während der Schrumpfung der Folie 17 längs eines Teilkreises durch den Schrumpfrevolver 19 transportiert, hier etwa entlang einer halben Umdrehung. Im Bereich einer Abgabestation 36 werden die Wärmeplatten 22,23 in die Öffnungsstellung gefahren. Die Haltebacken 28, 29 werden in einer zur Aufnahme einer Packung entgegengesetzten Bewegung betätigt. Die fertige Packung 10 wird in einem Bereich außerhalb des Schrumpfrevolvers 19 bewegt und an den Abförderer27 übergeben. Dieser ist als Gurtfördererausgebildet, nämlich mit einem mittigen Gurt 37, der Mitnehmer 38 aufweist. Diese sind in einem der Abmessung der Packungen 10 entsprechenden Abstand voneinander angeordnet, sodass die Packungen 10 in offene Taschen des Abförderers 27 eingelegt werden (Fig. 7, Fig. 8). Die Bewegungscharakteristik der Haltebacken 28, 29 ermöglicht die Ablage auf dem mit Abstand vom Schrumpfrevolver 19 laufenden Gurt 37. Eine feststehende Außenführung 39 sichert die Packungen 10 beim Weitertransport durch den Abförderer 27.The packs 10 are transported during the shrinkage of the film 17 along a pitch circle by the shrinking revolver 19, here approximately along half a revolution. In the area of a delivery station 36, the heat plates 22, 23 are moved into the open position. The holding jaws 28, 29 are actuated in a movement opposite to receive a pack. The finished package 10 is moved in an area outside of the shrinking revolver 19 and transferred to the discharge conveyor 27. This is designed as a belt conveyor, namely with a central belt 37, the driver 38 has. These are arranged in a distance corresponding to the dimensions of the packs 10, so that the packs 10 are inserted into open pockets of the discharge conveyor 27 ( Fig. 7 . Fig. 8 ). The movement characteristic of the holding jaws 28, 29 allows the tray on the belt 37 running at a distance from the shrinking turret 19. A stationary outer guide 39 secures the packs 10 during further transport through the discharge conveyor 27.

Die Ausgestaltung des Schrumpfrevolvers 19 ermöglicht eine exakte Anpassung des Schrumpfprozesses an technische Erfordernisse. So kann die Temperatur der Wärmeplatten 22,23 eingestellt werden, und zwar mit einer Veränderung während des Schrumpfprozesses. Des Weiteren ermöglicht die individuelle Bewegbarkeit der Wärmeplatten 22,23 ein Abheben von den Pakkungen 10, soweit dies erforderlich ist. Fig. 10 zeigt einen Betriebszustand mit insgesamt abgehobenen bzw. zurückgeschwenkten Wärmeplatten 22, 23. Dies ist beispielsweise erforderlich, wenn der Schrumpfrevolver 19 betriebsbedingt angehalten werden muss. Auch können erforderlichenfalls einzelne Packungen 10 ausgesondert werden durch Öffnung der Wärmeplatten 22, 23 und der Haltebacken 28, 29 der betreffenden Aufnahme 21.The design of the shrinking revolver 19 allows an exact adaptation of the shrinking process to technical requirements. Thus, the temperature of the heat plates 22, 23 can be adjusted with a change during the shrinking process. Furthermore, the individual mobility allows the heat plates 22,23 a lifting of the packages 10, if necessary. Fig. 10 shows an operating condition with a total of lifted or pivoted-back heat plates 22, 23. This is required, for example, when the shrinking revolver 19 must be stopped for operational reasons. Also, if necessary, individual packages 10 can be discarded by opening the heat plates 22, 23 and the holding jaws 28, 29 of the respective receptacle 21st

Alle Organe des Schrumpfrevolvers 19 sind an einem gemeinsamen, drehenden Träger angeordnet, nämlich an einer Revolverscheibe.All organs of the shrinking revolver 19 are arranged on a common, rotating support, namely on a turret disc.
