Description

Die Erfindung betrifft eine Verpackungseinrichtung für großformatige, quaderförmige, aus neben- und übereinander gestapelten quaderförmigen Gegenständen, insbesondere aus Zigarettenstangen bestehende Gebinde, mit einer Fördereinrichtung für Schlauchfolie zu einer Schneid- und Schweißstation zum Abtrennen und einseitigen Verschließen eines Folienabschnitts, einer Einrichtung zum Öffnen des Folienabschnitts, einem schrittweise antreibbaren Revolver, der für jede Schaltstation eine Halteeinrichtung für den geöffneten Folienabschnitt aufweist, die einen Aufnahmeraum für ein Gebinde begrenzt, einer in Einführposition des Revolvers vorgesehenen Einrichtung zum Einführen des Gebindes in einen Folienabschnitt sowie einer Schweißstation zum Verschließen des unverschweißten Endes des an einem Ende durch eine Schweißnaht verschlossenen, mit dem Gebinde befüllten Folienabschnitts.The invention relates to a packaging device for large-sized, cuboid, cuboid objects stacked next to and on top of one another, in particular containers consisting of cigarette sticks, with a conveying device for tubular film to a cutting and welding station for separating and closing a film section on one side, and a device for opening the film section , a step-by-step turret, which has a holding device for the open film section for each switching station, which limits a receiving space for a container, a device provided in the insertion position of the turret for inserting the container into a film section, and a welding station for closing the unwelded end of the one end closed by a weld seam, filled with the film section.

Aus der US-A-4 495 751 ist eine derartige Verpackungseinrichtung in Form einer Folieneinschweißeinrichtung bekannt, bei der eine Schlauchfolie von einer Bobine abgezogen und über einen Aufweitkopf auf einen Hohldorn geschoben und dort zusammengerafft wird. Der Hohldorn ist an einem Revolver angeordnet, der, nachdem eine bestimmte Länge an Schlauchfolie, die am nachlaufenden Ende verschweißt ist, aufgenommen worden ist, um 180° in eine Abgabeposition verschwenkt wird. In dieser werden zu verpackende Produkte durch den Hohldorn hindurch gegen die Schweißnaht geschoben, wodurch eine bestimmte Länge an Schlauchfolie vom Hohldorn abgezogen wird, die dann vom restlichen Teil der Schlauchfolie abgetrennt wird, während der verbleibende Teil wieder verschweißt wird. Das so von dem beutelartigen Schlauchfolienabschnitt aufgenommene Produkt wird mittels eines Transportbandes in eine Station transportiert, wo der Beutel evakuiert und auch am noch offenen Ende verschlossen wird. Diese Einrichtung ist für zu verpackende, verderbliche Lebensmittel wie Fleisch etc. konzipiert. Zum Verpacken von Gebinden aus quaderförmigen Gegenständen wie Zigarettenstangen ist diese Einrichtung nicht geeignet, zumal wenn diese möglichst platzsparend ausgebildet sein soll.From US-A-4 495 751, such a packaging device in the form of a film sealing device is known, in which a tubular film is pulled off a bobbin and opened over an expansion head a hollow mandrel is pushed and gathered there. The hollow mandrel is arranged on a turret which, after a certain length of tubular film, which is welded at the trailing end, has been taken up, is pivoted through 180 ° into a dispensing position. In this, products to be packaged are pushed through the hollow mandrel against the weld seam, as a result of which a certain length of tubular film is pulled off the hollow mandrel, which is then separated from the remaining part of the tubular film while the remaining part is welded again. The product thus taken up by the bag-like tubular film section is transported by means of a conveyor belt to a station, where the bag is evacuated and also closed at the still open end. This facility is designed for perishable food such as meat, etc. to be packaged. This device is not suitable for packaging containers made of cuboid objects such as cigarette sticks, especially if they are to be designed to be as space-saving as possible.

Aufgabe der Erfindung ist es, eine Verpackungseinrichtung der eingangs genannten Art zu schaffen, die platzsparend und einfach ausgebildet ein Folieneinschweißen und Kartonieren von Gebinden ermöglicht.The object of the invention is to provide a packaging device of the type mentioned at the outset which, in a space-saving and simple manner, enables film sealing and cartoning of containers.

Diese Aufgabe wird gelöst, daß mittels der Fördereinrichtung für Schlauchfolie letztere horizontal flach liegend in die Schneid- und Schweißstation in einer für den Folieneinschlag benötigten Länge plus einem Folienüberstand förderbar ist, aus der der Folienabschnitt auf die in Einführposition für ein Gebinde befindliche Halteeinrichtung in Förderrichtung der Schlauchfolie verschiebbar ist, die Einrichtung zum Einführen des Gebindes eine Sammelstation für flachliegende quaderförmige Gegenstände zum Zusammenstellen des Gebindes umfaßt, die Ausschubposition des Revolvers zum Ausschieben des befüllten Folienabschnittes gegenüber der Einführposition um 90° zur Seite hin versetzt ist und die Schweißstation zum Verschließen des unverschweißten Endes, die zwischen der Ausschubposition des Revolvers und einer Einschubposition eines als Förderer ausgebildeten Kartonierers angeordnet ist, mit in den Folienüberstand an gegenüberliegenden Seiten hiervon eingreifenden und auseinanderfahrbaren Spannern versehen ist.This object is achieved that by means of the conveying device for tubular film the latter can be conveyed horizontally lying flat in the cutting and welding station in a length required for the film wrapping plus a film protrusion from which the film section onto the holding device in the insertion position for a container in the conveying direction of the Tubular film is displaceable, the device for inserting the container comprises a collecting station for flat, cuboid objects for assembling the container, the ejection position of the revolver for pushing out the filled film section is offset by 90 ° to the side with respect to the insertion position, and the welding station for closing the unwelded end , which is arranged between the ejection position of the revolver and an insertion position of a cartoner designed as a conveyor, with un engaging in the film overhang on opposite sides thereof d extendable tensioners is provided.

Bei dieser Einrichtung wird nur ein Schlauchfolienabschnitt der jeweils benötigten Länge abgetrennt und auf eine Halteeinrichtung des Revolvers geschoben, die sich bereits in Einführposition für das Gebinde befindet. Hierbei werden die quaderförmigen Gegenstände des Gebindes zunächst flach liegend gesammelt und zu dem Gebinde zusammengestellt in den auf der Halteeinrichtung befindlichen Folienabschnitt geschoben, um dann um 90° gedreht zu werden. Hierdurch werden die quaderförmigen Gegenstände, durch den Folienabschnitt zusammengehalten, hochkant gestellt, wodurch die Grundfläche kleiner wird, so daß auch für den nachfolgenden Kartonierer, der als Elevatorförderer ausgebildet ist, eine entsprechend kleine Grundfläche benötigt wird.In this device, only a tubular film section of the required length is cut off and onto a holding device of the revolver, which is already in the insertion position for the container. Here, the cuboid objects of the container are first collected lying flat and put together to form the container and pushed into the film section on the holding device, in order to then be rotated through 90 °. As a result, the cuboid objects, held together by the film section, are placed upright, as a result of which the base area becomes smaller, so that a correspondingly small base area is also required for the subsequent cartoner, who is designed as an elevator conveyor.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention can be found in the following description and the subclaims.

Die Erfindung wird nachstehend anhand eines in den beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention is explained below with reference to an embodiment shown in the accompanying figures.

Fig. 1 und 2 zeigen perspektivisch, schematisiert und ausschnittweise einen Kartonierer für quaderförmige Stapel von Zigarettenstangen.1 and 2 show, in perspective, schematically and in detail, a cartoner for cuboid stacks of cigarette sticks.

Der dargestellte Kartonierer umfaßt einen schrittweise getaktet angetriebenen Elevatorförderer 1, der durch zwei gegenüberliegend angeordnete Gruppen von Riemen 2, die insbesondere als Zahnriemen ausgebildet und jeweils um obere und untere Umlenkrollen 3 geführt sind, einen Schacht entsprechend der Breite eines aufgerichteten Kartonzuschnitts 4 bildet. Gegebenenfalls können zwischen den Stillstandspositionen des Elevatorförderers 1 nicht dargestellte Stützrollen für die Riemen 2 angeordnet sein.The cartoner shown comprises an elevator conveyor 1 which is driven step-by-step and which forms a shaft corresponding to the width of an erected carton blank 4 by means of two oppositely arranged groups of belts 2, which are designed in particular as toothed belts and are each guided around upper and lower deflection rollers 3. If necessary, support rollers (not shown) for the belts 2 can be arranged between the standstill positions of the elevator conveyor 1.

Die Kartonzuschnitte 4 werden beispielsweise einem Kartonzuschnittmagazin entnommen und in einer Kartonaufrichtstation (wie sie beispielsweise aus der deutschen Patentanmeldung P 42 10 813.6 bekannt ist) zu einem Hohlkörper mit rechteckigem Querschnitt, der beidseitig offen ist, gegebenenfalls unter Verkleben entsprechender sich überlappender Teile aufgerichtet, um dann in den zwischen den Riemen 2 gebildeten Schacht des Elevatorförderers 1 mittels eines entsprechenden Schiebers in einer Stillstandsphase des Elevatorförderers 1 in dessen unterste Position eingeschoben zu werden, und zwar zwischen Halteleisten 5, die an den Riemen 2 angebracht sind und den aufgerichteten Kartonzuschnitt 4 unter- und oberseitig erfassen und damit den aufgerichteten Kartonzuschnitt 4 derart aufgerichtet halten, daß zum boden- und kopfseitigen Verschließen des Kartons dienende, am umlaufenden Seitenwandbereich befindliche, äußere bzw. innere Laschen 6 bzw. 7 und 8 bzw. 9 seitlich gegenüber dem Elevatorförderer 1 überstehen.The carton blanks 4 are taken, for example, from a carton blank magazine and in a carton erection station (as is known, for example, from German patent application P 42 10 813.6) to form a hollow body with a rectangular cross section that is open on both sides, possibly with the gluing of corresponding overlapping parts, and then erected to be inserted into the shaft between the belts 2 of the elevator conveyor 1 by means of a corresponding slide in a standstill phase of the elevator conveyor 1 in its lowest position, namely between holding strips 5 which are attached to the belts 2 and the erected cardboard blank 4 grasp the underside and top and thus keep the erected cardboard blank 4 erect such that the outer and inner tabs 6 or 7 and 8 or 9 located on the circumferential side wall area are used for closing the cardboard at the bottom and top, laterally opposite the elevator conveyor 1 survive.

Hierzu ist es zweckmäßig, das überschieben des aufgerichteten Kartonzuschnitts 4 in einer solchen Position des Elevatorförderers 1 vorzunehmen, in der die unteren Halteleisten 5 noch nicht ihre horizontale Position eingenommen haben, sondern noch schräg abwärts um einen Winkel von beispielsweise 45° gerichtet sind. Hierdurch ergibt sich genügend Spiel zum Einschieben des aufgerichteten Kartonzuschnitts 4, der beim Weiterfördern dann zwischen den entsprechenden Halteleisten 5 eingespannt wird.For this purpose, it is expedient to push the erected carton blank 4 in such a position of the elevator conveyor 1, in which the lower holding strips 5 have not yet assumed their horizontal position, but are still directed obliquely downward at an angle of, for example, 45 °. This results in sufficient play for inserting the erected carton blank 4, which is then clamped between the corresponding holding strips 5 during further conveying.

Während des Überführens des aufgerichteten Kartonzuschnitts 4 in die nächsthöhere Position infolge der schrittweisen Bewegung des Elevatorförderers 1 werden die vertikal verlaufenden Laschen 6 und gegebenenfalls 8 des aufgerichteten Kartonzuschnitts 4 durch entsprechende Führungsleisten (nicht dargestellt) leicht nach außen ausgestellt. In dieser Position werden ferner die bodenseitigen, horizontal verlaufenden Laschen 9 zur Bildung eines Bodens mittels entsprechender Falter (nicht dargestellt) einwärts um 90° in einer vertikale Stellung umgelegt. Ein vom Kartonzuschnitt 4 aufzunehmendes, großformatiges Gebinde 10 (ein quaderförmiger Block aus Zigarettenstangen 11) wird mittels eines (nicht dargestellten) Schiebers von der Kopfseite her in den aufgestellten Kartonzuschnitt 4 überschoben, wobei das Gebinde 10 gegen die in diesem Moment noch von den zugehörigen Faltern in ihrer um 90° einwärts umgelegten Stellung abgestützten Laschen 9 als Anschlag geschoben wird. Anschließend erfolgt das Schließen der oberen und unteren, kopfseitigen Lasche 7.During the transfer of the erected carton blank 4 into the next higher position due to the gradual movement of the elevator conveyor 1, the vertically extending tabs 6 and optionally 8 of the erected carton blank 4 are slightly exposed to the outside by corresponding guide strips (not shown). In this position, the bottom-side, horizontally extending tabs 9 are also folded inwards by 90 ° in a vertical position to form a bottom by means of appropriate folders (not shown). A large-sized container 10 to be picked up from the cardboard blank 4 (a cuboid block made of cigarette sticks 11) is pushed from the head side into the cardboard blank 4 that is set up by means of a slide (not shown), the container 10 being countered by the associated folders at that moment in their position turned by 90 ° inward brackets 9 is pushed as a stop. The upper and lower tabs 7 on the head side are then closed.

Während des Transports in die nächsthöhere Position werden die nun bereits geschlossenen Laschen 7, 9 mittels zwischen diesen Stillstandspositionen des Elevatorförderers 1 angeordneten Leimdüsen 12 beleimt. Als Leim kommt Heiß- oder Kaltleim infrage. Kaltleim wird insbesondere dann verwendet, wenn anschließend noch eine Verklebung des fertigen Kartons 13 mittels Klebeband 14 vorgenommen wird.During the transport to the next higher position, the tabs 7, 9, which are now closed, are glued by means of glue nozzles 12 arranged between these standstill positions of the elevator conveyor 1. Hot or cold glue can be used as glue. Cold glue is used especially when the finished product is then glued Cartons 13 is made by means of adhesive tape 14.

Mittels entsprechender Falter (nicht dargestellt) erfolgt ein Umfalten der noch offenen äußeren Laschen 6, 8 auf die beleimten inneren Laschen 7, 9 und ein Andrücken der äußeren Laschen 6, 8 an die inneren Laschen 7, 9 mittels horizontal verschiebbar geführter Andrückplatten 15 in der dritten Position von unten.Using a corresponding folder (not shown), the still open outer flaps 6, 8 are folded over onto the glued inner flaps 7, 9 and the outer flaps 6, 8 are pressed onto the inner flaps 7, 9 by means of horizontally displaceable pressure plates 15 in the third position from below.

Beim Transport in die vierte Position von unten läuft der nunmehr gefüllte und geschlossene Karton 13 in seinem mittleren Bereich zunächst gegen die Enden von zwei (naß- oder selbstklebenden) Klebebändern 14, die jeweils von einer entsprechenden Klebebandzuführung 16 bereit gestellt werden. Beim weiteren Transport wird das jeweilige Klebeband 14 entlang der Naht zwischen den beiden Paaren von benachbarten äußeren Laschen 6 bzw. 8 geführt und mittels einer entsprechend vorgespannten Rolle 17 angedrückt. Nach Durchlauf des Kartons 13 wird das jeweilige Klebeband 14 abgelängt und das freie Ende mittels der Rolle 17 auf die unten befindliche Seite des Kartons 13 umgelegt.When transported to the fourth position from below, the now filled and closed carton 13 initially runs in its central region against the ends of two (wet or self-adhesive) adhesive tapes 14, each of which is provided by a corresponding adhesive tape feed 16. During further transport, the respective adhesive tape 14 is guided along the seam between the two pairs of adjacent outer tabs 6 and 8 and pressed on by means of a correspondingly pre-tensioned roller 17. After the carton 13 has been passed through, the respective adhesive tape 14 is cut to length and the free end is folded onto the side of the carton 13 located below by means of the roller 17.

Aus der vierten Position wird der fertige Karton 13 in eine fünfte und Auswurfposition gefördert. Aus dieser Auswurfposition wirft ein schwenkbarer, an der unten befindlichen Seite des Kartons 13 angreifender Auswerfer 18 unter Drehung des Kartons 13 um 90° auf ein Abförderband 19.The finished carton 13 is conveyed from the fourth position into a fifth and ejection position. From this ejection position, a pivotable ejector 18, which engages on the side of the carton 13 located below, rotates the carton 13 by 90 ° onto a conveyor belt 19.

Die Gebinde 10 werden zum Schutz gegen Feuchtigkeit in eine Schlauchfolie 20 verpackt und darin eingeschweißt. Diese wird von einer Bobine 21 in flach gelegtem Zustand, bei dem die Schlauchfolie 20 mit beidseitigem Einschlag versehen ist, über Walzen 22 schrittweise zunächst einer Schweiß- und Schneidstation 23 in einer Horizontalebene liegend zugeführt, wo ein Folienabschnitt 24 der flach liegenden Schlauchfolie 20 an dem in Förderrichtung hinteren Ende mittels entsprechender, aufeinanderzu beweglicher und schließbarer Backen 25 zugeschweißt und abgetrennt wird.The containers 10 are packaged in a tubular film 20 for protection against moisture and are welded therein. This is fed by a bobbin 21 in a flat state, in which the tubular film 20 is provided with a wrap on both sides, gradually fed via rollers 22 to a welding and cutting station 23 lying in a horizontal plane, where a film section 24 of the flat lying tubular film 20 on the is welded and cut off in the conveying direction at the rear end by means of corresponding jaws 25 which can be moved and closed towards one another.

Vertikal bewegliche und in Förderrichtung des Folienabschnitts 24 gemeinsam verfahrbare Sauger 26 ergreifen den Folienabschnitt 24 an dem in Förderrichtung vorderen Ende an der Ober- und/oder Unterseite, um zunächst den Folienabschnitt 24 am vorderen Ende zu öffnen und ihn dann an einen Revolver 27 zu übergeben.Vertically movable suction cups 26, which can be moved together in the conveying direction of the film section 24, grip the film section 24 at the front end in the conveying direction on the top and / or underside in order to first open the film section 24 at the front end and then to be handed over to a revolver 27.

Der schrittweise angetriebene Revolver 27 umfaßt eine senkrecht zur Förderrichtung des Folienabschnitts 24 sich erstreckende Revolverscheibe 28, die insgesamt vier gleichmäßig über den Umfang verteilte, im wesentlichen rechteckige Ausnehmungen 29 aufweist. In Richtung auf die zuzuführenden Folienabschnitte 24 trägt die Revolverscheibe 28 sich senkrecht hierzu erstreckende Leisten 30 in einer Anordnung derart, daß ein in den aufgestellten Kartonzuschnitt 4 einzufüllender Stapel 31 aus Zigarettenstangen 11 durch die jeweils von vier Leisten 30 an den Ecken begrenzte Ausnehmung 29 hindurch paßt.The step-by-step driven turret 27 comprises a turret disk 28 which extends perpendicular to the conveying direction of the film section 24 and which has a total of four substantially rectangular recesses 29 distributed uniformly over the circumference. In the direction of the film sections 24 to be fed, the turret disk 28 carries strips 30 extending perpendicularly thereto in an arrangement such that a stack 31 of cigarette sticks 11 to be filled into the cardboard blank 4 that is set up fits through the recess 29 delimited by four strips 30 at the corners .

Die Leisten 30 können insbesondere als winkelförmige Leisten und gegebenenfalls als Spreizleisten ausgebildet sein. Sie können aber auch einwärts federvorgespannte Leisten oder Leistenpaare bilden, die durch das Einschieben eines Gebindes 10 gespreizt werden.The strips 30 can in particular be designed as angular strips and optionally as spreading strips. However, they can also form inwardly spring-loaded strips or pairs of strips, which are spread apart by inserting a container 10.

Wenn der Folienabschnitt 24 auf die in der Füllstation des Revolvers 27 befindlichen Leisten 30 benachbart zu einer Ausnehmung 29 geschoben ist, wird mittels eines Schiebers 32 der in einer Sammelstation 33 gebildete Stapel 31 und je nach Größe des Kartons auch ein weiterer in der gleichen oder einer weiteren Sammelstation 33 gebildeter Stapel 31 in den gespreizten Folienabschnitt 24 eingeschoben, wobei sich ein Folienüberstand 24a benachbart zur Revolverscheibe 28 ergibt. Gegebenenfalls können nicht dargestellte Stützbleche für den oder die in dem Folenabschnitt 24 befindlichen Stapel 31 an der Revolverscheibe 28 vorgesehen sein.When the film section 24 is pushed onto the strips 30 located in the filling station of the revolver 27 adjacent to a recess 29, the stack 31 formed in a collecting station 33 and, depending on the size of the carton, also another in the same or one, by means of a slide 32 Another collecting station 33 stack 31 formed inserted into the spread film section 24, wherein a film overhang 24a adjacent to the turret 28 results. If necessary, support plates (not shown) can be provided on the turret disk 28 for the stack or stacks 31 located in the film section 24.

Der Revolver 27 dreht sich nun um eine Schritteilung in eine Übergabeposition zum Elevatorförderer 1. Mittels eines beispielsweise unterseitig angreifenden Transporteurs 34 wird der befüllte Folienabschnitt 24 in Richtung auf den Elevatorförderer 1 transportiert und auf dem Weg zu diesem greift in den bezüglich der Transportrichtung rückwätigen Bereich des Folienabschnitts 24 oben und unten jeweils ein winkelförmiger Spanner 35 ein. Die Spanner 35 werden dann vertikal auseinander bewegt, so daß das hintere Ende des Folienabschnitts 24 im Bereich des Folienüberstands 24a in vertikaler Richtung gespannt wird, so daß sich zwei benachbarte, vertikale Kantenbereiche des Folienüberstands 24a ergeben, die mittels zweier horizontal gegeneinander beweglicher und vertikal verlaufender Schweißbacken 36 verschweißt werden (wobei die Spanner 35 kurz vor dem Schließen der Schweißbacken 36 aus dem Folienüberstand 24a herausgezogen werden). Das so gebildete, hermetisch durch den Folienabschnitt 24 eingeschlossene Gebinde 10 wird dann in den im Elevatorförderer 1 bereitsgestellten, aufgestellten Kartonzuschnitt 4 eingeschoben.The turret 27 now rotates a step division into a transfer position to the elevator conveyor 1. By means of a conveyor 34, which acts on the underside, for example, the filled film section 24 is transported in the direction of the elevator conveyor 1 and, on the way to it, engages in the area of the conveyor which is reverse with respect to the transport direction Foil section 24 above and below an angular tensioner 35 each. The tensioners 35 are then moved vertically apart, so that the rear end of the film section 24 is stretched vertically in the region of the film projection 24a, so that there are two adjacent, vertical edge regions of the film projection 24a, which are welded by means of two horizontally movable and vertically extending welding jaws 36 (the clamps 35 being pulled out of the film projection 24a shortly before the welding jaws 36 are closed). The container 10 thus formed, hermetically enclosed by the film section 24, is then inserted into the cardboard blank 4 already provided in the elevator conveyor 1.

Anstelle eines vierteiligen Revolvers 27 läßt sich auch ein zweiteiliger verwenden.Instead of a four-part revolver 27, a two-part can also be used.

Die Bildung der Gebinde 10 kann auch auf beiden Seiten des Elevatorförderers 1 erfolgen, wobei dann die Gebinde 10 auf beiden Seiten des Elevatorförderers 1 beispielsweise aus Stangen 11 von unterschiedlichen Zigarettenmarken gebildet werden. Dem Schieber zum Einschieben des Gebindes 10 kann auch auf der gegenüberliegenden Seite ein Abholer zugeordnet sein, wobei der Abholer gegebenenfalls als Schieber und der Schieber als Abholer beim Einschieben von der anderen Seite verwendet werden kann.The bundles 10 can also be formed on both sides of the elevator conveyor 1, the bundles 10 then being formed on both sides of the elevator conveyor 1, for example from rods 11 of different cigarette brands. A pickup can also be assigned to the slide for inserting the container 10 on the opposite side, the pickup possibly being used as a slide and the slide as a pickup when inserting from the other side.

Gegebenenfalls kann der Förderer 1 auch horizontal fördern, obwohl ein Elevatorförderer wegen seines geringen Platzbedarfs besonders vorteilhaft ist.If necessary, the conveyor 1 can also convey horizontally, although an elevator conveyor is particularly advantageous because of its small space requirement.

Als Antriebsaggregrate für die einzelnen Teile eignen sich elektrische Antriebe. Dies bietet einerseits die Möglichkeit, über Programmierung die Formatmaße zu ändern, und andererseits, die (über Schrittmotoren gesteuerten) Bewegungen durch Programm zu optimieren und dadurch die Leistung zu erhöhen.Electric drives are suitable as drive units for the individual parts. On the one hand, this offers the possibility to change the format dimensions via programming and, on the other hand, to optimize the movements (controlled by stepper motors) through the program and thereby increase the performance.

Der Kartonierer ermöglicht eine zumindest im wesentlichen symmetrische und damit konstruktiv günstige und aufeinanderfolgende Anordnung von Faltern, Beleimdüsen, Klebebandzuführungen u.dgl. auf beiden Seiten eines schrittweise geschalteten, einfach aufgebauten Förderers, so daß die einzelnen Komponenten gut zugänglich sind, so daß Störfälle leicht behoben werden können. Insbesondere können aufgestellte Kartonzuschnitte und/oder zu verpackende Gebinde von zwei gegenüberliegenden Seiten beispielsweise wechselweise dem Förderer zugeführt werden.The cartoner enables an at least essentially symmetrical and thus structurally advantageous and successive arrangement of folders, glue nozzles, adhesive tape feeders and the like. on both sides of a step-by-step, simply constructed conveyor, so that the individual components are easily accessible so that malfunctions can be easily remedied. In particular, erected cardboard blanks and / or packs to be packed can be fed alternately to the conveyor from two opposite sides, for example.
