Abstract

A process and an apparatus for erecting and closing a folding carton made from a one-piece board blank consisting of base, side and top panels connected by folding lines. The board blank is transported with its base panel (5) facing downwards through a device in which the side and top panels (7,9) are folded upwards and on top of each other. A fixed tongue (12) which is fastened at one end from above and is located inside the sleeve-shaped folding carton once the top panels have been folded into position, is provided to support the top panels (9). The transport unit has supports (14) which move with it, engage the underneath of the tongue and give it support against downward pressure.

Description

Die Erfindung betrifft ein Verfahren zum Aufrichten und Verschliessen einer Faltschachtel aus einem einteiligen Kartonzuschnitt mit über Faltlinien verbundenen Boden-, Wand- und Deckseiten sowie eine Vorrichtung zum Durchführen dieses Verfahrens.The invention relates to a method for erecting and closing a folding box from a one-piece cardboard blank with bottom, wall and cover sides connected by folding lines, and a device for carrying out this method.

Derartige Verfahren laufen im allgemeinen so ab, dass der Kartonzuschnitt mit seiner Deckseite auf das zu verpackende Gut gelegt wird, worauf von feststehenden Faltelementen die Wandseiten und dann die Bodenseiten eingefaltet werden. Zum Schluss werden die Bodenseiten verschlossen. Während dieses ganzen Vorganges ist es notwendig, das zu verpackende Gut so zu halten und zu führen, dass die Bodenseiten herangefaltet werden können.Such methods generally run in such a way that the cardboard blank is placed with its top side on the goods to be packed, whereupon the wall sides and then the bottom sides are folded in by fixed folding elements. Finally, the bottom sides are closed. During this entire process, it is necessary to hold and guide the goods to be packaged in such a way that the bottom sides can be folded up.

Es bietet sich nun an, den Falt- und Verschliessvorgang in entgegengesetzter Richtung ablaufen zu lassen, nämlich so, dass das zu verpackende Gut auf der Bodenseite des Kartonzu­schnitts aufliegt und die Wand- und Deckseiten nach oben gefaltet werden. Beim Verschliessvorgang werden dabei jedoch die Deckseiten auf dem Füllgut abgestützt, was bei empfind­lichem Füllgut nicht tragbar ist.It now makes sense to have the folding and closing process run in the opposite direction, namely in such a way that the goods to be packaged lie on the bottom side of the cardboard blank and the wall and top sides are folded upwards. During the closing process, however, the top sides are supported on the filling material, which is not acceptable for sensitive filling material.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung vorzuschlagen, bei denen eine möglichst einfache Vorrichtung ausreichend ist und gleichzeitig eine Beeinträchtigung des Füllgutes ausgeschlossen ist.The invention is based on the object of proposing a method and a device in which the simplest possible device is sufficient and at the same time an impairment of the filling material is excluded.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Kartonzuschnitt mit seiner Bodenseite auf einer Transport­einrichtung aufliegend durch eine Vorrichtung transportiert wird, in der zuerst die Wandseiten des Kartonzuschnitts um 90 Grad nach oben abgebogen und dann die Deckseiten um 90 Grad nach aussen umgefaltet werden, daraufhin werden die Deckseiten um eine feststehende Zunge bis zur gegenseitigen überdeckung nach innen umgefaltet und miteinander verklebt, worauf evtl. an den Stirnseiten vorgesehene Wandseiten ebenfalls umgefaltet und miteinander verklebt werden.According to the invention, this object is achieved in that the cardboard blank is transported with its bottom side lying on a transport device by a device in which the wall sides of the cardboard blank are first bent upwards by 90 degrees and then the cover sides are folded outwards by 90 degrees, then the deck sides are folded inwards around a fixed tongue to the point of mutual overlap and glued to one another, whereupon any wall sides provided on the end faces are also folded over and glued to one another.

Dieser Verfahrensablauf ist sehr einfach aufgebaut und läuft völlig unabhängig von einem evtl. vorhandenen Füllgut ab. Ein Abstützen am bzw. auf dem Füllgut kommt dabei nicht in Betracht.This procedure is very simple and takes place completely independently of any filling material that may be present. A support on or on the filling material is not an option.

Eine vorteilhafte Vorrichtung ist erfindungsgemäss dadurch gekennzeichnet, dass als Transporteinrichtung eine Kette vorgesehen ist, die Mitnehmer für den Kartonzuschnitt auf­weist, die mit Stützen versehen sind, welche eine nur ein­seitig gelagerte Zunge beim Durchlaufen und Falten der Deckseiten des Kartonzuschnittes von unten abstützen.An advantageous device according to the invention is characterized in that a chain is provided as the transport device, which has carriers for the cardboard blank, which are provided with supports which support a tongue, which is only supported on one side, from below when passing through and folding the cover sides of the cardboard blank.

Die nur zu einem U verformte Faltschachtel kann dabei ohne weiteres am einseitigen Lager der Zunge vorbeilaufen. Sodann wird die Faltschachtel um die Zunge herum zu einer Hülse geformt. Diese kann dann die Zunge zusammen mit den Stützen verlassen.The folding box, which is only deformed into a U, can easily pass the one-sided bearing of the tongue. The carton is then formed into a sleeve around the tongue. This can then leave the tongue together with the supports.

Sehr vorteilhaft ist auch eine erfindungsgemässe Weiterbil­dung, bei der eine Fördereinrichtung für das zu verpackende einstückige Füllgut vorgesehen ist, welche das Füllgut in die nach oben offene Faltschachtel einbringt.A further development according to the invention is also very advantageous, in which a conveying device is provided for the one-piece filling material to be packaged, which introduces the filling material into the folding box which is open at the top.

Da dieses Einbringen von oben während des Aufrichtens und Transportierens des Kartonzuschnittes erfolgt, ist damit ein besonders rationelles Befüllen ermöglicht.Since this introduction takes place from above during the erection and transport of the cardboard blank, a particularly efficient filling is made possible.

Ebenfalls sehr vorteilhaft ist es, wenn erfindungsgemäss die Mitnehmer für den Kartonzuschnitt gleichzeitig als Mitnehmer für das einstückige Füllgut ausgebildet sind und an diesem angreifen.It is also very advantageous if, according to the invention, the drivers for the cardboard blank are simultaneously designed as drivers for the one-piece filling material and act on it.

Dabei ist es besonders günstig, wenn die Mitnehmer mit einem Halsstück zum Angreifen am Kartonzuschnitt und einem in Transportrichtung darüber hinausragenden Kopfstück zum Angreifen am Füllgut ausgerüstet sind.It is particularly advantageous if the drivers are equipped with a neck piece for gripping the carton blank and a head piece protruding further in the transport direction for gripping the filling material.

Damit ist ein gleichmässiger Transport des Kartonzuschnittes und des Füllgutes mit einem festliegenden Versatz zueinander gewährleistet.This ensures a uniform transport of the carton blank and the contents with a fixed offset to each other.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht. Dabei zeigen:

  • Fig. 1 eine schematisierte Draufsicht auf eine Vorrichtung zum Aufrichten, Füllen und Ver­schliessen einer Faltschachtel,
  • Fig. 2 eine Seitenansicht eines Teils der Vorrich­tung nach Fig. 1 und
  • Fig. 3 eine Ansicht eines Mitnehmers für die Falt­schachtel.
An exemplary embodiment of the invention is illustrated in the drawing. Show:
  • 1 is a schematic plan view of a device for erecting, filling and closing a folding box,
  • Fig. 2 is a side view of part of the device according to Fig. 1 and
  • Fig. 3 is a view of a driver for the folding box.

Mit (1) ist in Fig. 1 eine Transporteinrichtung bezeichnet, die Bestandteil einer Vorrichtung zum Aufrichten und Ver­schliessen einer Faltschachtel ist. Die Faltschachtel wird aus einem flachliegenden Kartonzuschnitt (2) gebildet, der in mehreren Bearbeitungsstufen gefaltet wird.
Auf der Transporteinrichtung sind jeweils zwei paarweise angeordnete Mitnehmer (3) vorgesehen, von denen in Fig. 3 einer näher dargestellt ist. Diese beiden Mitnehmer greifen an der in Transportrichtung hinteren Kante des Kartonzu­schnittes (2) an und gewährleisten seinen sicheren Transport ohne seitliches Versetzen.1 in FIG. 1 denotes a transport device which is part of a device for erecting and closing a folding box. The folding box is formed from a flat cardboard blank (2) that is folded in several processing steps.
Two pairs of drivers (3) are provided on the transport device, one of which is shown in more detail in FIG. 3. These two drivers engage on the rear edge of the carton blank (2) in the transport direction and ensure its safe transport without lateral displacement.

Oberhalb der Transporteinrichtung sind zwei Faltlineale (4) angeordnet, welche den Bodenabschnitt (5) der Faltschachtel festhalten, während zwei weitere Faltschienen (6) ihre Seitenwände (7) senkrecht nach oben umfalten und im weiteren Verlauf abstützen. Im Anschluss daran sind zwei gekrümmte Schienen (8) angeordnet, welche die beiden Deckwände (9) unter Beibehaltung der senkrechten Stellung der Seitenwände um 90 Grad nach aussen umfalten. So aufgefaltet läuft die Faltschachtel unter einer Fördereinrichtung (10) durch, welche das Füllgut (11) herantransportiert und einzeln auf den Bodenabschnitt (5) aufschiebt. Die noch offene Falt­schachtel wird dann zusammen mit dem Füllgut, an welchem die Mitnehmer (3) ebenfalls angreifen, unter eine feststehende Zunge (12) transportiert, die über zwei Lager (13) nach oben hin befestigt ist, wie dies besonders aus Fig. 2 ersehen werden kann.
Nicht dargestellte Faltlineale falten die Deckenwände (9) um die Zung (12) herum, wodurch eine hülsenförmige Verpackung gebildet wird. Die Zunge (12) wird dabei durch Stützen (14) an ihrem freien, nicht befestigten Ende abgestützt, so dass der Faltdruck nicht auf das Füllgut (11) gelangt. Wie in Fig. 3 dargestellt, hat der Mitnehmer (3) ein Halsstück (15), mit dem er am Kartonzuschnitt angreift sowie ein Kopfstück (16), das zum Transport des Füllgutes dient. Auf beiden sitzt dann die Stütze (14), welche die Zunge (12) von unten her abstützt.
Mit einer solchen Einrichtung ist es möglich, auch sehr empfindliche Füllgüter auf schonende Art zu verpacken.Above the transport device, two folding rulers (4) are arranged which hold the bottom section (5) of the folding box, while two further folding rails (6) fold their side walls (7) vertically upwards and support them in the further course. Following this, two curved rails (8) are arranged which fold the two cover walls (9) outwards by 90 degrees while maintaining the vertical position of the side walls. Folded in this way, the folding box passes under a conveyor device (10) which transports the filling material (11) and pushes it individually onto the bottom section (5). The still open folding box is then transported together with the filling material, on which the drivers (3) also engage, under a fixed tongue (12), which is fastened upwards via two bearings (13), as is particularly evident from FIG. 2 can be seen.
Folding rulers, not shown, fold the ceiling walls (9) around the tongue (12), whereby a sleeve-shaped packaging is formed. The tongue (12) is supported by supports (14) on its free, non-fastened end so that the folding pressure does not reach the filling material (11). As shown in Fig. 3, the driver (3) has a neck piece (15) with which it engages the cardboard blank and a head piece (16) which serves to transport the filling material. The support (14), which supports the tongue (12) from below, then sits on both.
With such a device, it is possible to pack even very sensitive goods in a gentle manner.
