Description

Die Erfindung betrifft eine Vorrichtung zur Abpackung von gruppierten Einzelpackungen mittels Zuführung von Verpackungszuschnitten, insbesondere Kartonzuschnitten, aus mindestens einem Magazin in einer Zuführstation und anschließender, räumlich definierter, vom Verpackungstyp abhängiger, zumindest teilweiser Umschließung der Einzelpackungsgruppe durch den Verpackungszuschnitt in mindestens einer weiteren Verarbeitungssta-tion, wobei Zuführstation und Verarbeitungsstation einen gemeinsamen Drehteller beinhalten, dem die Einzelpackungsgruppen zugeführt, mittels einer Formeinrichtung mit einem Verpackungszuschnitt umschlossen und von dem die abgepackten Einzelpackungsgruppen entnommen werden, und dem ein Magazin für die Verpackungszuschnitte zugeordnet ist, die über Fördereinrichtungen dem Drehteller zuführbar sind.The invention relates to a device for packing grouped individual packs by feeding packaging blanks, in particular cardboard blanks, from at least one magazine in a feed station and then spatially defined, at least partially enclosing the individual pack group by the packaging blank in at least one further processing station, depending on the packaging type , wherein the feed station and processing station contain a common turntable, to which the individual pack groups are fed, enclosed with a packaging blank by means of a shaping device and from which the packaged individual pack groups are removed, and to which a magazine for the packaging blanks is assigned, which can be fed to the turntable via conveying devices.

Eine derartige Vorrichtung ist aus der DE-A 25 07 022 bekannt. Derartige Vorrichtungen werden eingesetzt, um gleichartige Verpackungen (z.B. Schokoladepackungen bei der genannten DE-A 25 07 022), die in eine geeigneten Gruppierungsstation zusammengefaßt wurden, beispielsweise übereinandergestapelt wurden, mit geeignetem Verpackungsmaterial, insbesondere Kartonzuschnitten, transport- und lagerfähig zusammenzufassen.Such a device is known from DE-A 25 07 022. Devices of this type are used to combine similar packaging (e.g. chocolate packs in the aforementioned DE-A 25 07 022), which have been combined in a suitable grouping station, for example stacked on top of one another, with suitable packaging material, in particular carton blanks, for transport and storage.

Der Einsatzbereich der vorbekannten "Sammelpackanlage" ist allerdings beschränkt: Der Drehteller bildet lediglich eine Verarbeitungsstation; der dort dargestellte Faltkasten ist als Teil des Drehtellers ("Faltrad") ausgebildet, für einen Arbeitstakt wird immer ein voller 360°-Umlauf des Faltrades benötigt.However, the area of application of the previously known "multi-pack system" is limited: the turntable merely forms a processing station; the folding box shown there is part of the turntable ("folding bike") trained, a full 360 ° rotation of the folding bike is always required for one work cycle.

Je nach Art und Menge der in einer Gruppe zusammengefaßten Einzelpackungen und je nach Art und Typ der gewünschten Verpackung können jedoch hierfür mehrere Einzel-Verpackungszuschnitte, insbesondere Kartonzuschnitte erforderlich sein, um den gewünschten Verpackungstyp zu erzeugen, beispielsweise eine mehrteilige, kartonähnliche Verpackung, die nach Entfernen eines Verpackungsteils (beispielsweise eines Deckels) dann gleichzeitig zur Präsentation der Ware, z.B. in einem Supermarkt verwendet werden kann.Depending on the type and quantity of the individual packs combined in a group and depending on the type and type of packaging desired, several individual packaging blanks, in particular cardboard blanks, may be required to produce the desired type of packaging, for example a multi-part, cardboard-like packaging that is removed a packaging part (for example a lid) then simultaneously for the presentation of the goods, for example can be used in a supermarket.

Die verschiedenen Arten der Einzelpackungen und die Anzahl der Einzelpackungen innerhalb einer Gruppe mit der spezifischen Besonderheit des Warenmaterials (beispielsweise Beutel) erfordert jedoch eine Vielzahl von Verpackungszuschnitten und damit einen erheblichen apparativen Aufwand, um diese Verpackungszuschnitte ggf. nach entsprechender Vorformung mit den gebildeten Einzelpackungsgruppen in Verbindung zu bringen und diese sicher und in der gewünschten Form zu umschließen. Eine derartige Verarbeitung ist mit der gattungsgemäßen Vorrichtung nicht möglich. Weitere bekannte Vorrichtungen dieser Art benutzen daher hierzu mehrere nacheinander geschaltete Stationen, die in der Regel über Bänder, Rollenförderer oder ähnliche Fördervorrichtungen miteinander verkettet sind.However, the different types of individual packs and the number of individual packs within a group with the specificity of the material of the goods (e.g. bags) require a large number of packaging cuts and thus a considerable outlay in terms of apparatus in order to connect these packaging cuts to the individual pack groups formed, if necessary after appropriate preforming to bring and enclose them safely and in the desired form. Such processing is not possible with the generic device. Further known devices of this type therefore use several stations connected in series, which are generally linked to one another via belts, roller conveyors or similar conveying devices.

Derartige Vorrichtungen haben einen erheblichen Platzbedarf und müssen in der Regel bei Wechsel der Verpackungsart aufwendig umgerüstet werden (sofern dies überhaupt möglich ist) bzw. es ist erforderlich, daß für jeden gewünschten Typ der Verpackung separate Verpackungsstraßen mit entsprechend hohem Investitionsaufwand angeschafft werden müssen.Devices of this type take up a considerable amount of space and generally have to be converted in a complex manner when the type of packaging is changed (if this is possible at all) or it is necessary for separate packaging lines to be purchased for each desired type of packaging with a correspondingly high investment outlay.

Es ist daher Aufgabe der Erfindung, die gattungsgemäße Vorrichtung derart weiterzubilden, daß ihr Einsatzbereich wesentlich erweitert ist, insbesondere auch die Verarbeitung von mehreren Verpackungszuschnitten möglich ist und daß sie trotzdem mit hohen Arbeitstakten arbeiten kann und besonders raumsparend ausgebildet werden kann.It is therefore an object of the invention to develop the generic device in such a way that its field of application is significantly expanded, in particular the processing of several packaging blanks is possible and that it can still work with high work cycles and can be designed to be particularly space-saving.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß im äußeren Umfangsbereich des Drehtellers sich auf diesem mehrere, sich bis zum Rand des Drehtellers erstreckende, rahmenförmige Aufnahmeeinrichtungen befinden, deren Anzahl die Arbeitstakte des Drehtellers bestimmt, mit mindestens einer Formeinrichtung zum Einschub oder zur Entnahme eines Verpackungszuschnittes bei jedem Arbeitstakt in die aus der jeweils gegenüberliegenden Aufnahmeeinrichtung auf dem Drehteller, und daß eine Anzahl N von Magazinen dem Umfangsbereich des Drehtellers zugeordnet ist, von denen von mindestens zwei bei jedem Arbeitstakt jeweils eine der Aufnahmeeinrichtungen mit einem Verpackungszuschnitt und/oder einer bereits vorgeformten Teilverpackung beschickbar ist.According to the invention, this object is achieved in that in the outer peripheral region of the turntable there are several frame-shaped receiving devices extending to the edge of the turntable, the number of which determines the work cycles of the turntable, with at least one shaping device for inserting or removing a packaging blank each work cycle into the respective opposite receiving device on the turntable, and that a number N of magazines is assigned to the peripheral area of the turntable, of which at least two of each of the receiving devices can be loaded with a packaging blank and / or a preformed partial packaging for each work cycle is.

Durch diese Konzeption, bei der sämtliche Arbeitsgänge auf einen gemeinsamen Drehtteller hin ausgerichtet sind bzw. dort stattfinden, kann die Vorrichtung äußerst kompakt ausgebildet werden, da durch die Anordnung solcher Vorrichtungen sowohl auf dem Drehteller als auch im unmittelbaren Peripheriebereich des Drehtellers, insbesondere auch über dem Drehteller, der zur Verfügung stehende Raum optimal ausgenutzt werden und insbesondere mit einer äußerst geringen Baulänge ausgekommen werden kann.Due to this concept, in which all operations are oriented towards a common turntable or take place there, the device can be made extremely compact, since by arranging such devices both on the turntable and in the immediate peripheral area of the turntable, in particular also above the Turntable, the available space can be optimally used and in particular with an extremely short overall length.

Die erfindungsgemäße Lösung erlaubt auch einen äußerst rationellen, modulartigen Aufbau der Vorrichtung in dem Sinne, daß die auf den Drehteller hin arbeitenden Magazine mit unterschiedlichen Verpackungszuschnitten beschickbar sind, so daß eine sehr große Variabilität hinsichtlich Art und Zuordnung der einzelnen Verpackungszuschnitte gewährleistet ist. Es können zum Teil insbesondere Verpackungen realisiert werden, die mit konventionellen Anlagen und auch der vorbekannten, gattungsmäßigen Vorrichtung gar nicht herstellbar sind.The solution according to the invention also allows an extremely rational, modular structure of the device in the sense that the magazines working on the turntable can be loaded with different packaging blanks, so that a very large variability with regard to the type and assignment of the individual packaging blanks is ensured. In particular, it is possible in part to produce packaging that cannot be produced with conventional systems or with the known generic device.

Die erfindungsgemäße Vorrichtung erhöht durch die Mehrfachausnützung des Drehtellers den Verarbeitungstakt um das Drei- bis Fünffache, so daß sie besonders geeignet zur Zusammenarbeit mit sehr schnellen Gruppierungsstationen ist, so daß insgesamt Verpackungsleistungen erreicht werden, die ebenfalls um das Drei- bis Fünffache höher sind als bei konventionellen Anlagen. Zusammen mit der Flexibilität infolge des modularen Aufbaus der erfindungsgemäßen Vorrichtung bedeutet dies eine erhebliche Produktivitätssteigerung und damit eine Verringerung der Verpackungskosten.Due to the multiple use of the turntable, the device according to the invention increases the processing cycle by three to five times, so that it is particularly suitable for cooperation with very fast grouping stations, so that overall packaging performances are achieved which are also three to five times higher than at conventional systems. Together with the flexibility due to the modular construction of the device according to the invention, this means a considerable increase in productivity and thus a reduction in packaging costs.

Bei einer genügend großen Anzahl von Magazinen mit verschiedenen Verpackungszuschnitts-Typen können die Magazine auch selektiv angesteuert werden, so daß beispielsweise bei insgesamt fünf Magazinen nur durch einen Umschaltvorgang zwei verschiedene Verpackungen, beispielsweise mit je zwei und je drei Verpackungszuschnitten erzeugt werden können; aufwendige Umrüstvorgänge können entfallen.With a sufficiently large number of magazines with different types of packaging blanks, the magazines can also be controlled selectively, so that, for example, with five magazines in total, only one switching operation can produce two different types of packaging, for example with two and three packaging blanks each; there is no need for time-consuming retrofitting.

Die Flexibilität der erfindungsgemäßen Vorrichtung ermöglicht insbesondere auch die Abwicklung von Form- oder Vorformabläufen unter Einbeziehung der Verpackungsgruppen selbst, die beispielsweise indirekt als Formstempel benutzt werden können. Die Magazine können je nach Bedarf auch zur Aufnahme horizontal liegender Zuschnitte ausgebildet sein, wobei dann die entsprechenden Formabläufe in vertikaler Richtung erfolgen. Insgesamt eröffnet sich auch die besondere Möglichkeit, gleiche Zuschnitte zu verarbeiten, wodurch Abfälle beim Zuschnittmaterial vermieden werden.The flexibility of the device according to the invention in particular also enables the handling of molding or preforming processes, including the packaging groups themselves, which can be used indirectly, for example, as mold stamps. Depending on requirements, the magazines can also be designed to accommodate horizontally lying blanks, in which case the corresponding form sequences take place in the vertical direction. Overall, there is also the special possibility of processing the same blanks, thereby avoiding waste in the blanks.

In einer vorteilhaften Ausgestaltung ist vorgesehen, daß die Magazine zumindest teilweise oberhalb der Ebene des Drehtellers angeordnet sind, wobei Fördereinrichtungen als im wesentlichen vertikal arbeitende Bandförderer ausgebildet sind, die die vertikal in ihrem zugeordneten Magazin stehenden Verpackungszuschnitte vereinzeln und einer der Aufnahmeeinrichtungen auf dem Drehteller zuführen.In an advantageous embodiment it is provided that the magazines are arranged at least partially above the level of the turntable, conveyor devices being designed as essentially vertically operating belt conveyors which separate the packaging blanks standing vertically in their assigned magazine and feed one of the receiving devices on the turntable.

Diese Ausgestaltung nutzt den in der Regel über einer Verpackungsmaschine zur Verfügung stehenden Raum aus, der normalerweise in entsprechenden Werksanlagen ohnehin vorhanden ist. Auch bei der vorbekannten Vorrichtung ist das dort vorgesehene (einzige) Magazin oberhalb der Ebene des Drehteller angeordnet, jedoch wirkt sich dieser Vorteil natürlich besonders stark aus, wenn mehrere Magazine untergebracht werden müssen.This configuration makes use of the space which is usually available above a packaging machine and which is normally present anyway in corresponding plant systems. In the known device too, the (only) magazine provided there is arranged above the level of the turntable, but of course this advantage has a particularly strong effect if several magazines have to be accommodated.

Die Vereinzelung und Zuführung über vertikal arbeitende Bandförderer ist außerdem äußerst platzsparend. Bei dieser Konzeption können auch Magazine über anderen Vorrichtungseinheiten angeordnet werden, beispielsweise über der dem Drehteller zuarbeitenden Gruppierungsstation und/oder über einem nachgeschalteten Ausgangsförderband. Letztlich können die Magazine mit ihrer Vereinzelungs- und Zuführeinrichtung also teilweise oder insgesamt in der "zweiten Etage" angeordnet werden, ohne für sich Stellfläche zu beanspruchen.The separation and feeding via vertically working belt conveyors is also extremely space-saving. With this concept, magazines can also be arranged above other device units, for example above the grouping station to be used for the turntable and / or above one downstream output conveyor belt. Ultimately, the magazines with their separating and feeding devices can thus be arranged partially or entirely on the "second floor" without taking up any space.

Weitere vorteilhafte Ausführungen des Erfindungsgedankens sind den Unteransprüchen zu entnehmen.Further advantageous embodiments of the inventive concept can be found in the subclaims.

An embodiment of the device according to the invention will now be explained in more detail with reference to drawings.
Show it:
  • 1 is a side view of the device,
  • Fig. 2 is a plan view of the device and

Vorab soll bemerkt werden, daß in den Figuren 1 und 2 aus Gründen der Deutlichkeit der Darstellung nicht jeweils alle Bauteile dargestellt sind.It should be noted in advance that not all components are shown in Figures 1 and 2 for reasons of clarity of representation.

In einem gemeinsamen Maschinenrahmen 30 ist die erfindungsgemäße Vorrichtung zusammen mit einer Gruppierungsstation 40 als Baueinheit ausgebildet, wobei die Gruppierungsstation 40 je nach Art der zusammenzufassenden Einzelpackungen unterschiedlich ausgebildet sein kann; deren konstruktive Ausbildung ist nicht Gegenstand der vorliegenden Erfindung. Grundsätzlich können beliebige Gruppierungsstationen mit der erfindungsgemäßen Vorrichtung zusammenarbeiten, beispielsweise eine Gruppierungsstation gemäß dem DE-GM 87 09 053, wo die mittels eines Bürstenförderers 40A gruppierten Einzelpackungen zur Verfügung gestellt werden.In a common machine frame 30, the device according to the invention is designed as a structural unit together with a grouping station 40, the grouping station 40 being able to be designed differently depending on the type of individual packs to be combined; their constructive training is not the subject of the present invention. In principle, any grouping stations can work with the device according to the invention, for example a grouping station according to DE-GM 87 09 053, where the individual packs grouped by means of a brush conveyor 40A are made available.

Der zentrale Teil der Vorrichtung besteht aus einem Drehteller 10, zu dessen taktweiser Drehung um die vertikale Achse X ein geeigneter Motor 10A im Maschinenrahmen 30 befestigt ist.The central part of the device consists of a turntable 10, for the clockwise rotation of which around the vertical axis X, a suitable motor 10A is fastened in the machine frame 30.

Im äußeren Umfangsbereich des Drehtellers 10 befinden sich jeweils um 90° versetzt vier sich bis zum Rand des Drehtellers 10 erstreckende Aufnahmeeinrichtungen 11A, B, C und D, die als zum Zentrum des Drehtellers 10 offene Rahmen ausgebildet sind. Entsprechend der Anzahl dieser Aufnahmevorrichtungen arbeitet der Drehteller folglich mit vier Arbeitstakten.In the outer circumferential area of the turntable 10 there are four receptacles 11A, B, C and D which extend to the edge of the turntable 10 and are designed as frames open to the center of the turntable 10. Depending on the number of these holding devices, the turntable therefore works with four work cycles.

Im Zentrum des Drehtellers 10 ist ortsfest ein Ausstoßstempel 17 gelagert, der über geeignete, beispielsweise pneumatische Antriebe durch den offenen Boden der jeweils gegenüberliegenden Aufnahmeeinrichtung (bei der dargestellten Arbeitsposition die Aufnahmeeinrichtung 11D) über den Rand des Drehtellers 10 hinaus verschiebbar ist.In the center of the turntable 10, an ejection ram 17 is mounted in a stationary manner, which, by means of suitable, for example pneumatic drives, through the open bottom of the opposite receiving device (In the working position shown, the receiving device 11D) can be moved beyond the edge of the turntable 10.

Gegenüber dem Ausstoßstempel 17 befindet sich außerhalb des Drehtellers 10 ein auf diesen radial zu bewegbarer Zuführstempel 19, mit dessen Hilfe die von der Gruppierungsstation 40 angelieferten Einzelverpakkungsgruppen nacheinander in die gegenüberliegende Aufnahmeeinrichtung (im dargestellten Ausführungsbeispiel die Aufnahmeeinrichtung 11B) und den dort bereits befindlichen Verpackungsteil eingeschoben werden können, wie dies weiter unten noch im einzelnen erläutert wird.Opposite the ejection ram 17 is located outside the turntable 10 a feed ram 19 which can be moved radially thereon, with the aid of which the individual packaging groups delivered by the grouping station 40 are successively inserted into the opposite receiving device (in the exemplary embodiment shown, the receiving device 11B) and the packaging part already located there can, as will be explained in more detail below.

Beim dargestellten Ausführungsbeispiel sind die von den Aufnahmeeinrichtungen 11A, B und D belegten Positionen mit Verpackungszuschnitten 13A, B, C, D und E beschickbar. Hierzu sind Magazine 12A...E vorgesehen, die jeweils zum Teil in den Figuren 1 und 2 dargestellt sind. In diesen Magazinen befinden sich verschiedene Kartonzuschnitte (Fig. 3), die zusammen eine vollständige Verpackung für die zugeführten Einzelpackungsgruppen 20 bilden.In the exemplary embodiment shown, the positions occupied by the receiving devices 11A, B and D can be loaded with packaging blanks 13A, B, C, D and E. Magazines 12A ... E are provided for this purpose, some of which are shown in FIGS. 1 and 2. In these magazines there are various cardboard blanks (FIG. 3) which together form a complete package for the supplied individual package groups 20.

Beim dargestellten Ausführungsbeispiel sind die Magazine 12A und 12B mit geneigtem Boden 120 ausgebildet,und die betreffenden Zuschnitte 13A, 13B, 13C stehen senkrecht in ihrem zugehörigen Magazin. Zur Vereinzelung und Förderung, der aus den Zuschnitten 13A und 13B gebildeten Teilverpackung dienen vertikale Bandförderer 14B, die diese Teilverpackung zu einer Formeinrichtung 15 transportieren, die die Verpackungszuschnitte 13C (Verpackungsboden) verarbeitet und dieses Ensemble dann mittels eines Stempels 14A in die gegenüberliegende Aufnahmeeinrichtung (bei der dargestellten Position die Aufnahmeeinrichtung 11A) einschiebt.In the illustrated embodiment, the magazines 12A and 12B are formed with an inclined bottom 120, and the respective blanks 13A, 13B, 13C are perpendicular in their associated magazine. Vertical belt conveyors 14B serve to separate and convey the partial packaging formed from the blanks 13A and 13B, which transport this partial packaging to a shaping device 15, which processes the packaging blanks 13C (packaging base) and then this ensemble by means of a stamp 14A in the opposite receiving device (in the receiving device 11A) in the position shown.

Oberhalb des Ausgangsbereichs der Gruppierungsstation 40 ist ein (nur in Fig. 2 dargestelltes) Magazin 12D mit den Zuschnitten 13D angeordnet, die gleichzeitig mit dem Einschub durch den Zuführstempel 19 der bereits gebildeten Teilverpackung hinzugefügt werden und eine Zwischenwand zwischen den zweireihig anzuordnenden Einzelverpackungen 20 bildet. Über einem gegenüber der Gruppierungsstation angeordneten Ausgangsförderband 18 ist ein weiteres Magazin 12E vorgesehen, in dem die als Verpackungsdeckel dienenden Zuschnitte 13E vor dem Ausstoß durch den Ausstoßstempel 17 zugeführt werden, so daß beim Ausstoßen mit Hilfe der nachfolgenden Formeinrichtung 16 die Verpackung komplettiert wird und vom nachgeschalteten Ausgangsförderband 18 abtransportiert wird.Above the exit area of the grouping station 40 there is a magazine 12D (only shown in FIG. 2) with the blanks 13D, which are added to the part packaging already formed as it is inserted through the feed ram 19 and form an intermediate wall between the individual packaging 20 to be arranged in two rows. Another magazine 12E is provided above an exit conveyor belt 18 arranged opposite the grouping station, in which the blanks 13E serving as packaging lids are fed through the ejection stamp 17 before ejection, so that the ejection with the help of the following shaping device 16 completes the packaging and the downstream one Output conveyor belt 18 is transported away.

Zur Verdeutlichung soll die Verpackung einer Packungsgruppe 20 im folgenden schrittweise nochmals beschrieben werden:For clarification, the packaging of a pack group 20 will be described again step by step in the following:

Die aus dem zugehörigen Magazin 12A/12B entnommenen, die späteren Seitenteile der Verpackung bildenden Zuschnitte 13A und 13B werden mit (nicht dargestellten) Einrichtungen vorgeformt und zu einem hochkant stehenden Rahmen verarbeitet, der sich dann vor dem Stempel 14A befindet. Über die Bandförderer 14B wird diese Teilverpackung nach unten befördert, gleichzeitig wird aus dem nicht dargestellten Magazin 12C der Verpackungszuschnitt 13C entnommen, der als Bodenteil dient. Beim Einschieben des aus den Verpackungszuschnitten 13A, 13B gebildeten Rahmens gegen den das Bodenteil bildenden Zuschnitt 13C durch eine geeignete Formeinrichtung 15 werden die Seitenflächen des Bodenteils 13C umgeklappt und ggf. verleimt, so daß in die rahmenförmig ausgebildete Aufnahmeeinrichtung 11A bereits eine aus Seitenteilen und Bodenteil gebildete Verpackung eingeschoben wird. Nach Beendigung dieses Arbeitsganges dreht sich der Drehteller um 90° weiter, so daß diese Aufnahmeeinrichtung nunmehr gegenüber dem Zuführstempel 19 für die gruppierten Einzelpackungen liegt. Gleichzeitig mit dem Einschub dieser Einzelpackungen wird aus dem Magazin 12D ein Zuschnitt zugeführt, der als Zwischenwand in der Verpackung dient. Nach zwei weiteren Takten wird dann die Position gegenüber dem Ausstoßstempel 17 erreicht, der die gefüllte Verpackung gegen den Deckelzuschnitt 13E drückt, und mittels der nachgeschalteten Formeinrichtung 16 wird dann dieser Deckel auf der Verpackung gebildet und ein Arbeitszyklus ist beendet. Die betreffende Aufnahmeeinrichtung ist somit wieder frei und kann nach einer weiteren Umdrehung des Drehtellers um 90° wieder ihre Ausgangsposition (11A) einnehmen und ein neuer Arbeitszyklus beginnt.The blanks 13A and 13B removed from the associated magazine 12A / 12B and forming the later side parts of the packaging are preformed with devices (not shown) and processed into an upright frame which is then located in front of the stamp 14A. This partial packaging is conveyed downwards via the belt conveyors 14B, at the same time the packaging blank 13C, which serves as the base part, is removed from the magazine 12C, not shown. When the frame formed from the packaging blanks 13A, 13B is pushed in against the blank 13C forming the base part by means of a suitable shaping device 15, the side surfaces of the bottom part 13C are folded over and possibly glued, so that one already formed from side parts and bottom part is formed in the frame-shaped receiving device 11A Packaging is inserted. After completion of this operation, the turntable rotates through 90 °, so that this receiving device is now opposite the feed ram 19 for the grouped individual packs. Simultaneously with the insertion of these individual packs, a blank is fed from the magazine 12D, which serves as an intermediate wall in the packaging. After two further cycles, the position opposite to the ejection stamp 17 is then reached, which presses the filled packaging against the lid blank 13E, and by means of the downstream molding device 16 this lid is then formed on the packaging and a work cycle is ended. The receiving device in question is thus free again and, after a further rotation of the turntable by 90 °, can return to its starting position (FIG. 11A) and a new work cycle begins.

Aus dieser Beschreibung wird leicht einsichtig, daß mit der erfindungsgemäßen Vorrichtung eine sehr große Variabilität hinsichtlich Art und Zuordnung der einzelnen Verpackungszuschnitte gewährleistet ist. Es können zum Teil auch Verpackungen realisiert werden, die mit konventionellen Anlagen gar nicht herstellbar sind.From this description it is easy to see that the device according to the invention ensures a very large variability with regard to the type and assignment of the individual packaging blanks. In some cases, packaging can also be realized that cannot be produced with conventional systems.

Die erfindungsgemäße Vorrichtung ist besonders geeignet zur Zusammenarbeit mit sehr schnellen Gruppierungsstationen, so daß Verpackungsleistungen erreicht werden können, die um das Drei- bis Fünffache höher sind als mit konventionellen Anlagen. Zusammen mit der Flexibilität infolge des modularen Aufbaus der erfindungsgemäßen Vorrichtung bedeutet dies eine erhebliche Produktivitätssteigerung und damit Verringerung der Verpackungskosten.The device according to the invention is particularly suitable for cooperation with very fast grouping stations, so that packaging performances which are three to five times higher than with conventional systems can be achieved. Together with the flexibility due to the modular design of the device according to the invention, this means a considerable increase in productivity and thus a reduction in packaging costs.

Die Flexibilität der Vorrichtung ermöglicht insbesondere auch die Abwicklung von Form- oder Vorformabläufen unter Einbeziehung der Verpackungsgruppen selbst, die beispielsweise indirekt als Formstempel benutzt werden können. Die Magazine können je nach Bedarf auch zur Aufnahme horizontal liegender Zuschnitte ausgebildet sein, wobei dann die entsprechenden Formabläufe in vertikaler Richtung erfolgen. Insgesamt eröffnet sich auch die besondere Möglichkeit gleiche Zuschnitte zu verarbeiten, wodurch Abfälle beim Zuschnittmaterial vermieden werden.The flexibility of the device in particular also enables the handling of mold or preform processes, including the packaging groups themselves, which can be used indirectly, for example, as mold stamps. Depending on requirements, the magazines can also be designed to accommodate horizontally lying blanks, in which case the corresponding form sequences take place in the vertical direction. Overall, there is also the special possibility of processing the same blanks, thereby avoiding waste in the blanks.
