Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von Packungen mit durch Klebung verbundenen Faltlappen, insbesondere Zigaretten-Packungen aus dünnem Karton, die nach Fertigstellung einem Trockenrevolver zuförderbar sind, der längs des Umfanges eine Mehrzahl von als durchgehende, achsparallele Öffnungen ausgebildeten Taschen aufweist, wobei die Zigaretten-Packungen in einer Beschickungsstation in die Taschen ein- und in einer zur Beschickungsstation in Drehrichtung des Trockenrevolvers versetzten Ausschubstation auf der gegenüberliegenden Seite ausschiebbar sind.The invention relates to a device for producing packs with folding flaps connected by adhesive, in particular cigarette packs made of thin cardboard, which after completion can be fed to a drying turret which has a plurality of pockets formed as continuous, axially parallel openings along the circumference, the cigarettes -Packages can be inserted into the pockets in a loading station and pushed out on the opposite side in an ejection station offset to the loading station in the direction of rotation of the drying turret.

Bei der Herstellung von quaderförmigen Zigaretten-Packungen mit durch Klebung verbundenen Faltlappen ist es üblich, die Zigaretten-Packungen nach dem Fertigungsprozeß in einen Trockenrevolver einzuführen und in diesem unter Aufrechterhaltung des fortlaufenden Fertigungsprozesses für eine Weile zum Abbinden des Leimes zu halten. Ein derartiger Trockenrevolver muß geeignet sein, eine große Anzahl von Packungen aufzunehmen, damit diese bei einer Umdrehung des Trockenrevolvers während einer ausreichenden Verweilzeit in diesem bleiben.In the production of cuboid cigarette packs with folding tabs connected by gluing, it is customary to put the cigarette packs into one after the manufacturing process Introduce a dry turret and hold it there for a while to keep the glue setting while maintaining the ongoing manufacturing process. Such a drying turret must be able to accommodate a large number of packs so that they remain in the drying turret for a sufficient dwell time during a rotation.

Bekannt ist ein Faltrevolver mit am Umfang sternförmig angeordneten, achsparallel verlaufenden Taschen, je zur Aufnahme einer Mehrzahl von in Axialrichtung nebeneinanderliegenden Packungen. Bei diesem Faltrevolver werden während des Aufenthalts der Packungen in den Taschen die radial außenliegenden Seiten mit Wärme beaufschlagt und sodann durch Andrücken an die Stirnflächen mit diesen sowie miteinander verbunden. Die Packungen mit den gesiegelten Stirnlappen werden gruppenweise aus den Taschen in achsparalleler Richtung ausgeschoben. (DE-B-1 270 476).A folding turret is known with pockets arranged in a star shape on the circumference and running parallel to the axis, each for receiving a plurality of packs lying next to one another in the axial direction. In this folding turret, the radially outer sides are subjected to heat during the stay of the packs in the pockets and then connected to them and to one another by pressing on the end faces. The packs with the sealed front flaps are pushed out of the pockets in groups in the axis-parallel direction. (DE-B-1 270 476).

Des weiteren ist ein aus zwei hintereinanderliegenden Zellrädern bestehender Trockenrevolver bekannt, wobei jedes Zellrad längs des Umfangs eine Mehrzahl als durchgehende, achsparallele Öffnungen ausgebildete Taschen je zur Aufnahme einer Packung aufweist. Die Packungen werden den Taschen eines Zellrades in einem Kopfschließrevolver zugefördert und mittels Schieber zugeführt. Nach einer Verweilzeit der Packungen bedingt durch eine Weiterbewegung des Zellrades werden die Packungen mittels Schieber in das zweite Zellrad übergeschoben. In Umfangsrichtung des Trockenrevolvers versetzt zum Kopfschließrevolver ist ein Doppelschieber zum Ausschub der Packungen auf ein Abtransportorgan angeornet.(DE-A-3 046 065).Furthermore, a drying turret consisting of two cell wheels lying one behind the other is known, wherein each cell wheel has a plurality of pockets designed as continuous, axially parallel openings along the circumference, each for receiving a pack. The packs are fed into the pockets of a cellular wheel in a head-closing revolver and fed by means of a slide. After the packs have dwelled due to further movement of the cellular wheel, the packs are pushed into the second cellular wheel by means of a slide. In the circumferential direction of the drying revolver, offset to the head-closing revolver, a double slide is arranged to eject the packs onto a removal member (DE-A-3 046 065).

Der vorstehende, bekannte Faltrevolver ist hinsichtlich Funktion und Aufbau nicht mit einem Trockenrevolver gleichzusetzen, da der Faltrevolver die Funktion eines Trockenrevolvers nicht übernehmen kann. Gleichwohl ist der aus zwei Zellrädern bestehende Trockenrevolver aufgrund der Einzel-Packungsaufnahme nicht als Trockenrevolver mit hoher Leistung und vor allem hohem Durchsatz an Packungen einer leistungsfähigen Packungsmaschine geeignet. Insbesondere fehlt es bei den genannten, bekannten Revolvern an einem wirksamen Mittel zur Positionierung der Packungs-Gruppe innerhalb der Tasche.The above, known folding turret is not to be equated with a drying turret in terms of function and structure, since the folding turret cannot perform the function of a drying turret. Nevertheless, the dry revolver consisting of two cellular wheels is due to the Single pack receptacle is not suitable as a drying turret with high performance and, above all, high throughput of packs from a powerful packaging machine. In particular, the known revolvers mentioned lack an effective means of positioning the pack group within the pocket.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Trockenrevolver mit Taschen zur Aufnahme jeweils einer Gruppe von Packungen dahingehend weiterzuentwickeln und zu verbessern, daß die Packungs-Gruppen bei hoher Leistung jeweils exakt in den Taschen positioniert werden und ohne Gefahr von Beschädigungen weitertransportiert werden können.The invention is therefore based on the object to further develop and improve a dry turret with pockets for receiving a group of packs in such a way that the pack groups are positioned exactly in the pockets at high power and can be transported without risk of damage.

Zur Lösung dieser Aufgabe ist die Vorrichtung durch folgende Merkmale gekennzeichnet: Die Taschen sind je zur Aufnahme einer Packungs-Gruppe aus mehreren nebeneinanderliegenden Zigaretten-Packungen ausgebildet, den Taschen ist austrittsseitig im Bereich der Beschickungsstation ein ortsfest gelagerter Taschenanschlag zugeordnet, der Taschenanschlag weist einen in Anschlagstellung in die zu beschickende Tasche ragenden Anschlagvorsprung auf, gegen den die in die Tasche in der Beschickungsstation eintretenden Zigaretten-Packungen der Packungs-Gruppe zuförderbar sind, der Taschenanschlag ist außerhalb des Trockenrevolvers bewegbar gelagert, derart, daß zum Weiterbewegen des Trockenrevolvers der Taschenanschlag aus der Anschlagstellung innerhalb der Tasche in eine Stellung außerhalb des Bereichs des Trockenrevolvers bewegbar ist.To achieve this object, the device is characterized by the following features: the pockets are each designed to accommodate a pack group of several cigarette packs lying next to one another, the pockets are assigned a fixed pocket stop on the outlet side in the area of the loading station, the pocket stop has one in the stop position in the pocket to be loaded projecting stop against which the cigarette packs entering the pocket in the loading station of the pack group can be fed, the pocket stop is movably mounted outside the drying turret, such that the pocket stop from the stop position for moving the drying turret further is movable within the pocket into a position outside the area of the drying turret.

Bei der Ausbildung des Trockenrevolvers werden Packungs-Gruppen in den Taschen des Trockenrevolvers jeweils in der Beschickungsstation durch einen dort wirkenden Anschlag positioniert. Außerhalb der Beschickungsstation ist dieser Anschlag nicht erforderlich. Durch die Bewegbarkeit des Anschlags ist gewährleistet, daß die in der jeweiligen Tasche angestauten Packungen störungsfrei, nämlich ohne Anlage an den Anschlag, weitertransportiert werden können bei Drehung des Trockenrevolvers.When the drying turret is formed, pack groups are positioned in the pockets of the drying turret in the loading station by a stop acting there. This stop is not required outside the loading station. The movability of the stop ensures that the packs pent up in the respective bag are free of interference, namely without contact with the stop, can be transported further when the drying turret is rotated.

Nach einem weiteren Merkmal der Erfindung ist eine der Seitenwände der Taschen bewegbar ausgebildet, nämlich als Teil eines zweiarmigen Hebels und steht unter federbelastung, derart, daß die Packungen in den Taschen außerhalb des Bereichs der Beschickungsstation und der Ausschubstation federelastisch mit Druck beaufschlagt werden.According to a further feature of the invention, one of the side walls of the pockets is designed to be movable, namely as part of a two-armed lever and is under spring loading, such that the packs in the pockets are subjected to spring elastic pressure outside the area of the loading station and the extension station.

Weitere Merkmale der Erfindung ergeben sich aus den Patentansprüchen.Further features of the invention emerge from the patent claims.

Das in den Zeichnungen dargestellte Ausführungsbeispiel betrifft eine Verpackungsmaschine bzw. Teile derselben zum Herstellen von quaderförmigen Zigaretten-Packungen 10. Vorzugsweise handelt es sich dabei um Klappschachteln (Hinge-Lid-Packungen) aus dünnem Karton. Der Teil der Verpackungsmaschine, der sich auf die Herstellung der eigentlichen Packung 10 bezieht, ist im einzelnen nicht dargestellt, entspricht jedoch vorzugsweise der Ausführungsform gemäß DE-OS 24 40 006.The exemplary embodiment shown in the drawings relates to a packaging machine or parts thereof for producing cuboid-shaped cigarette packs 10. These are preferably hinged boxes (hinge-lid packs) made of thin cardboard. The part of the packaging machine which relates to the production of the actual package 10 is not shown in detail, but preferably corresponds to the embodiment according to DE-OS 24 40 006.

Die Zigaretten-Packungen 10 sind so ausgebildet, daß im Bereich schmaler Seitenflächen 11 einander überdeckenden Seitenlappen durch Kleber miteinander verbunden sind. Die Zigaretten-Packungen 10 mit noch nicht ausgehärtetem Kleber werden auf einer Packungsbahn 12 zugefördert, durch Anheben einem Übergaberevolver 13 zugeführt und von diesem an einen ersten Trockenrevolver 14 übergeben. Dieser ist vorzugsweise so ausgebildet wie in der DE-OS 26 32 968 beschrieben, nämlich mit einer Mehrzahl von radial gerichteten Taschen 15, je zur Aufnahme einer Zigaretten-Packung 10. Die Taschen 15 sind so ausgebildet, daß ein formierender Druck auf die Zigaretten-Packungen 10 ausgeübt und dadurch deren quaderförmige Gestalt korrigiert und stabilisiert wird. Die Packungen werden zweckmäßigerweise in diesem ersten Faltrevolver 14 leicht erwärmt.The cigarette packs 10 are designed in such a way that in the area of narrow side surfaces 11 side flaps overlapping one another are connected to one another by adhesive. The cigarette packs 10 with adhesive that has not yet cured are conveyed on a packing track 12, fed to a transfer turret 13 by lifting and transferred from the latter to a first drying turret 14. This is preferably designed as described in DE-OS 26 32 968, namely with a plurality of radially directed pockets 15, each for receiving a cigarette pack 10. The pockets 15 are designed so that a forming pressure on the cigarette Packs 10 exercised and thereby their cuboid shape is corrected and stabilized. The packs are expediently slightly heated in this first folding turret 14.

Nach einer nahezu vollständigen Drehung des Trockenrevolvers 14 werden die Packungen durch einen Ausstoßer 16 aus den Taschen 15 ausgeschoben und in einen unmittelbar an den Trockenrevolver 14 anschließenden Bandförderer eingeführt, der zugleich Zuförderer 17 für einen weiteren (zweiten) Trockenrevolver 18 ist.After an almost complete rotation of the drying turret 14, the packs are pushed out of the pockets 15 by an ejector 16 and introduced into a belt conveyor directly connected to the drying turret 14, which is also a feed conveyor 17 for a further (second) drying turret 18.

Der Zuförderer 17 besteht aus einem umlaufenden, endlosen Obergurt 19 und einem ebenfalls endlos umlaufenden Untergurt 20. Zwischen diesen finden die Zigaretten-Packungen 10 Aufnahme in einer Relativstellung, bei der die langgestreckten Seitenflächen 11 nach unten und oben gerichtet sind, Stirnflächen 21 also zu den Seiten hinweisen.The feed conveyor 17 consists of an encircling, endless top chord 19 and an endless encircling also Lower flange 20. Between these, the cigarette packs 10 are received in a relative position, in which the elongated side surfaces 11 are directed downwards and upwards, that is to say end surfaces 21 point to the sides.

Die Zigaretten-Packungen 10 werden durch den Zuförderer 17 mit Abstand voneinander unmittelbar dem zweiten Trockenrevolver 18 zu und in Taschen 22 desselben eingefördert. Dabei werden durch Aufstauen der Zigaretten-Packungen 10 Packungsgruppen 23 gebildet, die je zur Aufnahme in einer Tasche 22 bestimmt sind. Bei dem vorliegenden Ausführungsbeispiel besteht jede einer Taschen 22 zugeordnete Packungsgruppe 23 aus vier Zigaretten-Packungen 10.The cigarette packs 10 are fed by the feed conveyor 17 at a distance from one another directly to the second drying turret 18 and into pockets 22 of the same. In this case, 10 pack groups 23 are formed by stowing the cigarette packs, each of which are intended to be received in a pocket 22. In the present exemplary embodiment, each pack group 23 assigned to a pocket 22 consists of four cigarette packs 10.

Der Trockenrevolver 18 ist in einer um 90° versetzten Ebene zum ersten Trockenrevolver 14 angeordnet, beide in aufrechten Ebenen. Die Taschen 22 des zweiten Trockenrevolvers 18 sind als in Axialrichtung durchgehende Kammern ausgebildet, durch die die Packungsgruppe 23 in Axialrichtung hindurchgeschoben wird. Jede Tasche besteht aus zwei Seitenwänden 24 und 25, von denen im vorliegenden Falle eine (Seitenwand 25) bewegbar ist. Diese ist Teil eines zweiarmigen Wandhebels 26, der um ein Drehlager 27 verschwenkt wird und dessen freier Stützarm mit einer Tastrolle 28 auf einer ortsfesten Kurvenscheibe 29 abgestützt ist. Eine (Zug- )Feder 30, die am freien Arm des Wandhebels 26 angreift, bewirkt, daß die Seitenwand 25 in Schließstellung belastet wird. Im Bereich einer Beschickungsstation 31 sowie einer Ausschubstation 32 werden die Seitenwände 25 jeweils durch Auflaufen der Tastrolle 28 auf eine Erhöhung der Kurvenscheibe 29 gegen die Spannung der Feder 30 geöffnet. Die radial außenliegende Seite der Taschen 22 wird durch eine ortsfeste Ringwand 33 begrenzt. Auf der gegenüberliegenden Seite bildet eine geschlossene mit umlaufende Tragscheibe 34, an der auch die feststehenden Seitenwände 24 und die schwenkbaren Seitenwände 25 angebracht sind, die Begrenzung der Tasche 22. Die Packungen 10 werden zwischen den Seitenwänden 24 und 25 durch Festklemmen fixiert.The drying turret 18 is arranged in a plane offset by 90 ° to the first drying turret 14, both in upright planes. The pockets 22 of the second drying turret 18 are designed as continuous chambers in the axial direction, through which the packing group 23 is pushed in the axial direction. Each pocket consists of two side walls 24 and 25, one of which (side wall 25) is movable in the present case. This is part of a two-armed wall lever 26 which is pivoted about a pivot bearing 27 and the free support arm of which is supported on a stationary cam 29 by a feeler roller 28. A (tension) spring 30, which acts on the free arm of the wall lever 26, causes the side wall 25 to be loaded in the closed position. In the area of a loading station 31 and an extension station 32, the side walls 25 are opened in each case by running the feeler roller 28 on an increase in the cam disc 29 against the tension of the spring 30. The radially outer side of the pockets 22 is fixed by a Ring wall 33 limited. On the opposite side, a closed, circumferential support disk 34, to which the fixed side walls 24 and the pivotable side walls 25 are attached, forms the boundary of the pocket 22. The packs 10 are fixed between the side walls 24 and 25 by clamping.

Dieser ist bei dem vorliegenden Ausführungsbeispiel als zweiarmiger Hebel ausgebildet mit einem Anschlagvorsprung 36, der von der Austrittsseite her in die Tasche 22 hineinragt. Ein Schwenklager 37 ist an einer feststehenden Haltescheibe 38 angebracht. Ein von dem Anschlagvorsprung 36 anliegender Schenkel 39 des Taschenanschlags 35 ist mit einer Laufrolle 40 auf einer topfförmigen Kurvenscheibe 41 abgestützt. Eine am Taschenanschlag 35 angreifende (Zug-)Feder 42 bewirkt, daß die Laufrolle 40 ständig an der Kurvenscheibe 41 anliegt, der Anschlagvorsprung 36 demnach in Richtung des Zurückziehens belastet ist.The cigarette packs 10 transported by the feed conveyor 17 into the pocket 22 located in the loading station 31 run against a pocket stop 35 on the opposite side. In the present exemplary embodiment, this is designed as a two-armed lever with a stop projection 36 that extends from the exit side protrudes into the pocket 22. A pivot bearing 37 is attached to a fixed holding disc 38. A leg 39 of the pocket stop 35 abutting the stop projection 36 is supported by a roller 40 on a cup-shaped cam 41. A (tension) spring 42 engaging the pocket stop 35 causes the roller 40 to bear against the cam disk 41, so that the stop projection 36 is loaded in the direction of retraction.

Bei Einfördern der Packungs-Gruppe 23 in die Tasche 22 befindet sich der Anschlagvorsprung 36 in der in die Tasche 22 hineinbewegten Stellung (ausgezogene Linie in Fig. 6). Die Packungsgruppe 23 läuft gegen den Anschlagvorsprung 36. Bei Weiterbewegung des Trockenrevolvers 18 wird der Anschlagvorsprung 36 zurückgezogen (gestrichelte Stellung). Die Zigaretten-Packungen 10 können nun belastungsfrei in der Tasche 22 mit bewegt werden. Eine abgeschrägte Einlaufkante 43 in einer Revolverseitenwand 44 bewirkt eine Ausrichtung der Packungs-Gruppe 23 in der Tasche 22 durch leichte Verschiebung zur gegenüberliegenden Seite hin (Revolverseitenwand 45).When the pack group 23 is fed into the pocket 22, the stop projection 36 is in the position moved into the pocket 22 (solid line in FIG. 6). The pack group 23 runs against the stop projection 36. When the drying turret 18 moves further, the stop projection 36 is withdrawn (dashed position). The cigarette packs 10 can now be moved in the pocket 22 without stress. A beveled lead-in edge 43 in a turret side wall 44 brings about an alignment of the pack group 23 in the pocket 22 by slight displacement to the opposite side (turret side wall 45).

Die Taschen 22 sind so ausgebildet, daß die in Höhe einer horizontalen Mittelebene zugeführten Zigaretten-Packungen 10 mit den Stirnflächen 21 in Radialrichtung nach außen bzw. innen gerichtet in den Taschen 22 Aufnahme finden. Die Seitenflächen 11 sind in Umfangsrichtung weisend.The pockets 22 are designed in such a way that the cigarette packs 10, which are fed in at a horizontal central plane, are received in the pockets 22 with the end faces 21 directed radially outwards or inwards. The side surfaces 11 point in the circumferential direction.

Um einen störungsfreien Weitertransport der Packungsgruppe 23 in der Tasche 22 zu gewährleisten, werden die nachfolgenden Zigaretten-Packungen im Bereich des Zuförderers 17 momentan angehalten. Im vorliegenden Falle werden die in Bewegungsrichtung vornliegenden (aufgestauten) Zigaretten-Packungen 10 durch Festklemmen angehalten. Zu diesem Zweck ist seitlich neben dem Zuförderer 17 eine Klemmplatte 46 beweglich gelagert. Dieser ist an einem langgestreckten Hebelarm 47 angebracht, der durch ein geeignetes Getriebe 48 pulsierend angetrieben wird. In der in Fig. 6 gezeigten Stellung werden mehrere Zigaretten-Packungen mit ihren Stirnflächen 21 gegen eine feststehende Seitenführung 49 neben dem Zuförderer 17 gedrückt. Sobald die nächste Tasche 22 in die Beschickungsstation 31 bewegt worden ist, wird die Klemmplatte 46 zurückbewegt, so daß die aufgestauten Zigaretten-Packungen 10 in die Tasche 22 gefördert werden können. Die Seitenführung 49 ist bei dem vorliegenden Ausführungsbeispiel mit der Revolverseitenwand 44 verbunden.In order to ensure trouble-free further transport of the pack group 23 in the pocket 22, the following cigarette packs are momentarily stopped in the area of the feed conveyor 17. In the present case, the cigarette packs 10 lying in front in the direction of movement are stopped by clamping. For this purpose, a clamping plate 46 is movably mounted on the side next to the feed conveyor 17. This is attached to an elongated lever arm 47 which is driven by a suitable gear 48 pulsating. In the position shown in FIG. 6, a plurality of cigarette packs are pressed with their end faces 21 against a fixed side guide 49 next to the feed conveyor 17. As soon as the next pocket 22 has been moved into the loading station 31, the clamping plate 46 is moved back so that the pent-up cigarette packs 10 can be conveyed into the pocket 22. The side guide 49 is connected to the turret side wall 44 in the present exemplary embodiment.

Der Trockenrevolver 18 wird bei der Darstellung in Fig. 4 in Gegenuhrzeigersinn angetrieben. Die Zigaretten-Packungen befinden sich nahezu während einer gesamten Umdrehung des Trockenrevolvers 18 in dessen Taschen 22. Die Ausschubstation 32 ist unmittelbar unterhalb der Beschickungsstation 31 gebildet. Die Packungsgruppe 23 wird durch einen Ausstoßer 50 aus der betreffenden Tasche 22 herausgefördert über ein gewundenes Zwischenstück 51 bis in einen Abförderer 52. Letzterer besteht ebenfalls aus oberen und unteren Gurten, zwischen denen die in bezug auf Klebungen ausgehärteten Packungen Aufnahme finden. Das Zwischenstück 51 besteht aus schräg- bzw. bogenförmig verlaufenden Führungswänden als Übergang von der Tasche 22 zum in horizontaler Ebene sich erstreckenden Abförderer 52.The drying turret 18 is driven counterclockwise in the illustration in FIG. 4. The cigarette packs are located in the pockets 22 of the drying revolver 18 for almost an entire revolution. The ejection station 32 is formed immediately below the loading station 31. The pack group 23 is conveyed out of the relevant pocket 22 via an ejector 50 meandering intermediate piece 51 into a discharge conveyor 52. The latter also consists of upper and lower belts, between which the packs cured with regard to adhesives are accommodated. The intermediate piece 51 consists of inclined or curved guide walls as a transition from the pocket 22 to the removal conveyor 52 extending in the horizontal plane.

Der Ausstoßer 50 ist als abgewinkelter Arm ausgebildet mit einem horizontalen Schenkel 53, der bei hin- und hergehender Bewegung des Ausstoßers 50 durch die zu entleerende Tasche 22 hindurchbewegt wird bis zum Abförderer 52. Der übrige Teil des Ausstoßers 50 ist seitlich neben dem Trockenrevolver 18 verschiebbar gelagert, und zwar auf im wesentlichen horizontalen, achsparallel zum Trockenrevolver 18 gerichteten Tragstangen 54. Der Antrieb des so ausgebildeten Ausstoßers 50 erfolgt durch eine Kurbel 55 mit umlaufender Antriebsscheibe 56 und Kurbelstange 57. Letztere ist (schwenkbar) mit einem den Ausstoßer 50 tragenden Schlitten 58 verbunden. Dieser ist gleitend auf den Tragstangen 54 gelagert.The ejector 50 is designed as an angled arm with a horizontal leg 53 which, when the ejector 50 moves back and forth, is moved through the pocket 22 to be emptied up to the discharge conveyor 52. The remaining part of the ejector 50 can be moved laterally next to the drying turret 18 mounted, namely on essentially horizontal, parallel to the drying turret 18 support rods 54. The ejector 50 thus formed is driven by a crank 55 with a rotating drive disk 56 and crank rod 57. The latter is (pivotable) with a carriage 58 carrying the ejector 50 connected. This is slidably supported on the support rods 54.

Die äußere Ringwand 33 sowie die Revolverseitenwände 44 und 45 des Trockenrevolvers 18 sind im Bereich der Ausschubstation 32 und im Bereich der Beschickungsstation 31 unterbrochen bzw. mit Ausnehmungen 59 und 60 versehen. Die Ausnehmung 59 im Bereich der Ausschubstation 32 ermöglicht den freien Durchtritt des Ausstoßers 50 bzw. des Schenkels 53.The outer ring wall 33 and the turret side walls 44 and 45 of the drying turret 18 are interrupted in the region of the extension station 32 and in the region of the loading station 31 or are provided with recesses 59 and 60. The recess 59 in the region of the ejection station 32 enables the ejector 50 or the leg 53 to pass freely.

Der weitere Aufbau des Trockenrevolvers 18 in der vorliegenden Ausführungsform ergibt sich vor allem aus Fig. 6 und 7. Die Revolverseitenwände 44 und 45 bilden mit der Ringwand 33 ein geschlossenes Gehäuse.The further structure of the drying turret 18 in the present embodiment results primarily from FIGS. 6 and 7. The turret side walls 44 and 45 form a closed housing with the ring wall 33.

In diesem ist auch der Antrieb für den Trockenrevolver 18 untergebracht. Über ein Zahnradgetriebe 61 wird ein Hauptrad 62 angetrieben, welches auf einer feststehenden mittigen Achse 63 gelagert ist. Mit dem Hauptrad 62 umlaufend und deshalb mit diesem verbunden ist die Tragscheibe 34, an dessen äußeren Umfang die Taschen 22 angebracht sind. An der Tragscheibe 34 ist auch die Kurvenscheibe 41 als seitlich abstehender Kranz angeordnet. Die den Taschen 22 bzw. der beweglichen Seitenwand 25 derselben zugeordnete Kurvenscheibe 29 ist mit der Achse 63 verbunden. Bei dem gezeigten Ausführungsbeispiel ist die Kurvenscheibe 29 mit der Haltescheibe 38 identisch, der äußere Umfang dieser Haltescheibe 38 bildet zugleich die Kurvenscheibe 29. Die Haltescheibe ist mit einer Öffnung 64 versehen, durch die der Schenkel 39 des Taschenanschlags 35 samt Laufrolle 40 hindurchtritt, um Anlage an der Kurvenscheibe 41 zu erhalten.The drive for the drying turret 18 is also accommodated in this. A main gear 62 is driven via a gear transmission 61 and is mounted on a fixed central axis 63. With the main wheel 62 rotating and therefore connected to it, the support disk 34, on the outer circumference of which the pockets 22 are attached. The cam disk 41 is also arranged on the support disk 34 as a laterally protruding ring. The cam plate 29 assigned to the pockets 22 or the movable side wall 25 thereof is connected to the axis 63. In the exemplary embodiment shown, the cam disc 29 is identical to the retaining disc 38, the outer circumference of this retaining disc 38 also forms the cam disc 29. The retaining disc is provided with an opening 64 through which the leg 39 of the pocket stop 35 together with the roller 40 passes through for planting to get on the cam 41.

Bei dem vorliegenden Ausführungsbeispiel sind die Kapazitäten der Trockenrevolver 14 und 18 so ausgelegt, daß die Packungen jeweils etwa 15 sec. in jedem Trockenrevolver Aufnahme finden. Die gesamte Trockenzeit von 30 sec. ist ausreichend, um stabile Packungen zu erhalten. Der zweite Trockenrevolver 18 kann - wie der erste Trockenrevolver 14 - in geeigneter Weise beheizt sein.In the present exemplary embodiment, the capacities of the drying turrets 14 and 18 are designed such that the packs are accommodated in each drying turret for about 15 seconds each. The total drying time of 30 seconds is sufficient to obtain stable packs. The second drying turret 18 - like the first drying turret 14 - can be heated in a suitable manner.
