Description

Die Erfindung betrifft eine Vorrichtung zum Aufrichten eines Klappbehälters, der eine Bodenplatte und an der Bodenplatte angelenkte, einander paarweise gegenüberliegende Seiten- und Stirnwände bildende Klappwände aufweist, mit einer Schwenkeinrichtung für die auf die eingeschwenkten Stirnwände abgeklappten Seitenwände und mit den freien Längsrand der Stirnwände jeweils umfassenden, mit Schwenktrieben verbundenen Schwenkarmen für die Stirnwände.The invention relates to a device for erecting a folding container, which has a bottom plate and hinged to the bottom plate, pairwise opposite side and end walls forming folding walls, with a pivoting device for the folded on the end walls pivoted side walls and with the free longitudinal edge of the end walls each comprehensive , Swivel arms connected to swivel drives for the end walls.

Derartige Klappbehälter, die im zusammengelegten Zustand aufeinander platzsparend stapelbar sind finden insbesondere beim Transport von Lebensmitteln oder dergleichen Verwendung und sind üblicherweise aus Kunststoffen gefertigt. Im zusammengefalteten Zustand sind die Seiten- und Stirnwände im Wesentlichen parallel zu der Bodenplatte angeordnet, wobei die Seitenwände auf den eingeklappten Stirnwänden oder umgekehrt abgelegt werden. Beim Aufklappen werden die Seiten- und Stirnwände in eine zur Bodenplatte senkrecht ausgerichtete Lage übergeführt, also um 90° aufgeschwenkt, und in dieser Lage mittels Rastelementen zueinander verrastet.Such folding containers, which are stackable to save space in the folded state find particular use in the transport of food or the like use and are usually made of plastics. In the folded state, the side and end walls are arranged substantially parallel to the bottom plate, wherein the side walls are placed on the folded end walls or vice versa. When unfolding the side and end walls are transferred to a vertically oriented to the bottom plate layer, so pivoted by 90 °, and locked in this position by means of locking elements to each other.

Vorrichtungen zum Aufrichten derartiger Klappbehälter sind beispielsweise aus der DE 94 05 299 U1 bzw. aus der EP 1 320 456 B1 bekannt. Diese bekannten Vorrichtungen umfassen hintereinander angeordnete Arbeitsbereiche, eine Übernahmestation, eine Auffaltstation und eine Ausgabestation, wobei die Klappbehälter den einzelnen Stationen über ein Transportmittel, insbesondere ein Förderband, zugeleitet werden. Die zusammengeklappten Klappbehälter werden an der Übernahmestation abgegeben, mittels des Transportmittels an die Aufrichtstation weitergeleitet, dort aufgerichtet und anschließend an eine Ausgabestation weitertransportiert. Aus der EP 1320456 B1 ist es bekannt, zusätzlich eine Prüfeinrichtung vorzusehen, welche prüft ob die aufgeklappten Klappbehälter ordnungsgemäß aufgestellt worden sind, insbesondere ob die Klappwände ordnungsgemäß zueinander verrastet wurden. Bei den bekannten Vorrichtungen ist jeder Seiten- und Stirnwand eine eigene Aufrichteinrichtung zugeordnet.Devices for erecting such folding containers are for example from the DE 94 05 299 U1 or from the EP 1 320 456 B1 known. These known devices comprise successively arranged working areas, a transfer station, a Auffaltstation and an output station, wherein the folding containers are the individual stations via a transport, in particular a conveyor belt, fed. The folded folding containers are delivered to the transfer station, forwarded by the means of transport to the Aufrichtstation, erected there and then transported to an output station. From the EP 1320456 B1 it is known to additionally provide a test device, which checks whether the unfolded Folding container have been properly placed, especially if the flap walls were properly locked to each other. In the known devices, each side and end wall is assigned its own righting device.

Zum Aufstellen werden beispielsweise zuerst die Seitenwände mittels eines die Seitenwände stirnseitig greifenden Schwenkantriebes aufgeklappt und anschließend die Stirnwände von den freien Längsrand der Stirnwände jeweils umfassenden, mit Schwenkantrieben verbundenen, Schwenkarmen aufgestellt, wonach die Klappwände mittels einer Klemmvorrichtung zueinander verrastet werden. Diese bekannten Schwenkarme umfassen eine an einem Maschinengestell verschwenkbar gelagerte Parallelogrammhebelanordnung, wobei der Schwenkarm über einen Schubstößel mit einer Kulissensteuerung in Antriebsverbindung steht. Dabei handelt es sich um eine konstruktiv aufwändige, wartungsintensive und verschleißanfällige Konstruktion. Zudem kann es beim Aufklappen der Stirnwände aufgrund der Kinematik zu Klemmungen der Stirnwände bzw. zu unnötigen Krafteinwirkungen auf die Stirnwände kommen.To set up, for example, first the side walls are opened by means of a lateral side walls cross-swivel drive and then the end walls of the free longitudinal edge of the end walls each comprehensive, associated with rotary actuators, pivot arms set up, after which the flap walls are locked to each other by means of a clamping device. These known pivot arms comprise a parallelogram lever arrangement pivotably mounted on a machine frame, wherein the pivot arm is drive-connected to a slide control via a pushrod. It is a structurally complex, maintenance-intensive and wear-prone construction. In addition, when the end walls are opened due to the kinematics, clamping of the end walls or unnecessary force effects on the end walls may occur.

Eine Vorrichtung zum Aufstellen von Schachteln ist aus der US 3 013 477 A1 bekannt, gemäß der zum Aufrichten der Schachtelwände mit Zahnradsektoren versehene Hebel vorgesehen sind, die über Zahnstangen angetrieben werden. Diese Vorrichtung ist aber nicht zum Aufrichten von Klappbehältern geeignet.A device for erecting boxes is from the US 3,013,477 A1 in accordance with the provided for erecting the box walls with gear sectors levers are provided, which are driven by racks. However, this device is not suitable for erecting folding containers.

Der Erfindung liegt die Aufgabe zugrunde eine Vorrichtung der eingangs geschilderten Art zu schaffen, welche konstruktiv möglichst einfach und störunanfällig ausgebildet ist und dabei ein rasches Aufstellen von Klappbehältern ermöglicht, ohne die aufzustellenden Klappbehälter dabei übermäßig mechanisch zu beanspruchen.The invention has for its object to provide a device of the type described above, which is designed to be as simple as possible and störunanfällig, thereby allowing a quick installation of hinged containers without claiming to be erected folding container thereby excessively mechanically.

Die Erfindung löst diese Aufgabe dadurch, dass die Schwenkarme in Kreisbogenführungen verschiebbar gelagert sind, deren Achsen mit den Anlenkachsen der zugehörigen Stirnwände zumindest im Wesentlichen zusammenfallen.The invention solves this problem in that the pivot arms are slidably mounted in circular arc guides whose axes with the pivot axes the associated end walls at least substantially coincide.

Mit der verschiebbaren Lagerung der Schwenkarme in den Kreisbogenführungen wird wegen der verhältnismäßig geringen auf die Vorrichtung einwirkenden Kräfte nicht nur eine einfache und wartungsarme Konstruktion mit sehr hohen Standzeiten geschaffen, sondern kann auch in besonders einfacher Weise ein für die Klappbehälter schonendes Aufklappen gewährleistet werden, da unnötige Krafteinwirkungen auf den Klappbehälter beim Aufklappvorgang durch die mit den Anlenkachsen der zugehörigen Stirnwände zumindest im wesentlichen zusammenfallenden Achsen der Kreisbogenführung vermieden werden. Geringe diesbezügliche Toleranzabstände zwischen den Achsen spielen nur eine untergeordnete Rolle. Die erfindungsgemäße Schwenkvorrichtung kann mit einfachen Mitteln vollständig gekapselt und somit gegenüber Umwelteinflüssen, wie Staub, Feuchtigkeit oder dgl. bei schmaler Bauweise abgedichtet werden.With the sliding bearing of the pivot arms in the circular arc guides is not only created a simple and low-maintenance construction with very long service lives because of the relatively low forces acting on the device, but can also be ensured in a particularly simple manner gentle for the folding container unfolding, as unnecessary Force effects on the folding container during Aufklappvorgang be avoided by the at least substantially coinciding axes of the circular arc guide with the pivot axes of the associated end walls. Low tolerance distances between the axes play only a minor role. The pivoting device according to the invention can be completely encapsulated with simple means and thus sealed against environmental influences, such as dust, moisture or the like. Narrow design.

Zum Aufklappen umfasst der Schwenkarm die aufzuklappende Stirnwand vorzugsweise mit einer Art Kralle, wonach der Schwenkarm in der Kreisbogenführung mittels des Stelltriebes von der Greifstellung in die Aufstellstellung um rund 90° verlagert wird. Es versteht sich dabei von selbst, dass die Schwenkarmlänge dabei an verschiedenste Klappbehältergrößen individuell anpassbar ausgestaltet sein kann. Seiten- und Stirnwände können je nach Klappbehälterform und Größe wahlweise sowohl die Längs- als auch die Querwand der aufzustellenden Klappbehälter sein. Bei der Darstellung der Erfindung sind Stirnwände stets Wände, deren Anlenkachsen an der Bodenplatte im Wesentlichen parallel zur Transportrichtung der Fördereinrichtung für die Klappbehälter durch die Vorrichtung zum Aufrichten des Klappbehälters parallel liegen.For unfolding, the swivel arm preferably includes the fold-up end wall with a kind of claw, after which the swivel arm is displaced in the circular arc guide by means of the actuating drive from the gripping position to the erect position by approximately 90 °. It goes without saying that the Schwenkarmlänge can be configured individually adapted to a variety of folding container sizes. Depending on the folding container shape and size, side and end walls can be either the longitudinal wall or the transverse wall of the hinged containers to be erected. In the presentation of the invention, end walls are always walls whose pivot axes are parallel to the bottom plate substantially parallel to the transport direction of the conveyor for the folding container through the device for erecting the folding container.

Zur Gewährleistung einer möglichst einfachen Konstruktion empfiehlt es sich, wenn die Schwenkarme die Stirnwände umgreifende Mitnehmer aufweisen, die entlang der Schwenkarme mit Hilfe von Stelltrieben zwischen einer Freigabe und einer Greifstellung verlagerbar sind. Die Schwenkarmlänge lässt sich beispielsweise mittels hinsichtlich ihrer Länge verstellbarer Schwenkarme bzw. durch die Lage der Mitnehmer über die Stelltriebe in einfacher Weise rasch an unterschiedliche Wandhöhen verschiedener Klappbehälter anpassen, wodurch kein umständliches Umrüsten der Anlage zum Aufstellen verschiedener Klappbehältergrößen erforderlich ist, da die Länge der Schwenkarme von einer Steuereinrichtung her in Abhängigkeit der Größe des aufzustellenden Klappbehälter problemlos individuell eingestellt werden kann.To ensure the simplest possible construction, it is recommended that the pivot arms have the end walls encompassing driver, along the pivot arms by means of actuators between a Release and a gripping position are displaced. The Schwenkarmlänge can be quickly adapted to different wall heights of different folding containers, for example by means of adjustable length swivel arms or by the position of the driver via the actuator in a simple manner, whereby no cumbersome retooling of the system for setting up different folding container sizes is required because the length of the pivot arms can be easily adjusted individually by a control device depending on the size of the folding container to be set up.

Besonders einfache Konstruktionsverhältnisse ergeben sich, wenn die Schwenkarme ein zur Kreisbogenführung konzentrisches Zahnkranzsegment aufweisen, das mit einer an einen Stelltrieb angeschlossenen Zahnstange kämmt. Dadurch lassen sich kurze Aufstellzeiten für den Klappbehälter bei geringer mechanischer Belastung von Klappbehälter und Vorrichtung erzielen.Particularly simple construction conditions arise when the pivot arms have a circular arc guide concentric sprocket segment which meshes with a rack connected to an actuator. As a result, short setup times for the folding container with low mechanical load of folding container and device can be achieved.

Eine Vorrichtung zum Aufrichten eines Klappbehälters 1, der eine Bodenplatte 2 und an der Bodenplatte 2 angelenkte, einander paarweise gegenüberliegende Seiten- und Stirnwände 3, 4 bildende Klappwände aufweist umfasst gemäß dem dargestellten Ausführungsbeispiel unter anderem eine in einem Rahmen 5 angeordnete Schwenkeinrichtung 6 für die auf die eingeschwenkten Stirnwände 4 abgeklappten Seitenwände 3 und zudem den freien Längsrand der Stirnwände 4 jeweils umfassende, mit Schwenktrieben 7 verbundene Schwenkarme 8 für die Stirnwände 4.A device for erecting a folding container 1, which has a bottom plate 2 and on the bottom plate 2 hinged, pairwise opposite side and end walls 3, 4 forming folding walls comprises according to the illustrated embodiment, inter alia, arranged in a frame 5 pivoting device 6 for on the pivoted end walls 4 folded side walls 3 and also the free longitudinal edge of the end walls 4 each comprehensive, associated with pivoting drives 7 pivot arms 8 for the end walls. 4

Im dargestellten Ausführungsbeispiel ist für jede Stirnwand 4 ein eigener Schwenkarm 8 und für jede Seitenwand 3 eine eigene Schwenkeinrichtung 6 vorgesehen. Des weiteren gehört der Vorrichtung eine Transporteinrichtung 9 mit einem nicht dargestellten Förderer, wie einer Förderkette, einem Förderband oder dgl. zu, mit dem der Klappbehälter 1 von einer Aufgabeposition (in Fig. 3 links) zu einer Aufstellposition (Fig. 3 mitte) und von dort zu einer Ausgabeposition transportiert werden kann. Der Klappbehälter 1 wird mittels des Förderbandes 9 von der Aufgabeposition zur Aufrichtposition verlagert, wo er beispielsweise mittels nicht eingezeichneter Anschläge bzw. Positionierelemente in seine ordnungsgemäße Aufstelllage ausgerichtet wird. Dazu können am Rahmen geeignete, hinsichtlich der Klappbehältergröße gegebenenfalls automatisch einstellbare bzw. von einer Steuereinrichtung her einstellbare Anschläge bzw. Positionierhilfen angeordnet sein.In the illustrated embodiment, a separate pivot arm 8 is provided for each end wall 4 and a separate pivoting device 6 for each side wall 3. Furthermore, the device includes a transport device 9 with a conveyor, not shown, such as a conveyor chain, a conveyor belt or the like. To which the folding container 1 from a loading position (in Fig. 3 left) to an installation position ( Fig. 3 middle) and can be transported from there to a delivery position. The folding container 1 is displaced by means of the conveyor belt 9 from the loading position to the erecting position, where it is aligned, for example, by means of not marked stops or positioning in its proper installation position. These can be arranged on the frame suitable, with respect to the folding container size optionally automatically adjustable or adjustable by a controller ago stops or positioning.

Zum Aufstellen werden zunächst die Seitenwände 3 mittels die Seitenwände 3 stirnseitig greifender Schwenkeinrichtungen 6 von ihrer horizontalen Lage in ihre aufgeklappte vertikale Lage verschwenkt. Dazu umfassen die Schwenkeinrichtungen 6 Stellmotoren 10, die je einen in Richtung der Seitenwand 3 verlagerbaren und die Seitenwand 3 stirnseitig greifenden Schwenkhebel 11 betätigen. Sind die Seitenwände 3 aufgeklappt, schwenken die Stelltriebe 7 die Schwenkarme 8 auf die Stirnwände 4 ein, umgreifen die Stirnwände 4 an ihrem freien Längsrand und verlagern die Stirnwände in ihre vertikale aufgestellte Lage. Abschließend werden die Klappwände mittels einer oberhalb des Klappbehälters 1 angeordneten Klemmeinrichtung 12 zueinander verrastet. Zur Schaffung einer erfindungsgemäßen Vorrichtung, die nur eine geringe Arbeitsbreite quer zur Transportrichtung der Klappbehälter 1 durch die Vorrichtung aufweist, die zudem hohe Aufstellgeschwindigkeiten und Standzeiten gestattet, sind die Schwenkarme 8 in Kreisbogenführungen 13 verschiebbar gelagert, deren Achsen 14 mit den Anlenkachsen 15 der zugehörigen Stirnwände 4 zumindest im Wesentlichen zusammenfallen.To set up the side walls 3 are first pivoted by means of the side walls 3 frontally pivoting devices 6 of its horizontal position in its unfolded vertical position. For this purpose, the pivoting devices comprise 6 servomotors 10 which each actuate a pivoting lever 11 which can be displaced in the direction of the side wall 3 and which engages the side wall 3 on the front side. If the side walls 3 are opened, the adjusting drives 7 pivot the pivot arms 8 onto the end walls 4, embrace the end walls 4 at their free longitudinal edge and displace the end walls into their vertical erected position. Finally, the flap walls are latched to one another by means of a clamping device 12 arranged above the folding container 1. To create a device according to the invention, which has only a small working width transverse to the transport direction of the folding container 1 through the device, which also allows high installation speeds and service life, the pivot arms 8 are slidably mounted in circular arc guides 13, the axes 14 with the pivot axes 15 of the associated end walls 4 at least substantially coincide.

Die Schwenkarme 8 weisen dabei die Stirnwände 4 umgreifende Mitnehmer 16 auf, die entlang der Schwenkarme 8 mit Hilfe von Stelltrieben 17, im dargestellten Ausführungsbeispiel Druckluftzylinder, zwischen eine Freigabe- und einer Mitnahmestellung verlagerbar sind. Mit diesen Stelltrieben 17 bzw. mit zusätzlichen vorzusehenden Stelleinrichtungen, kann zudem die Schwenkarmlänge eingestellt und somit an verschiedene Kistenhöhen angepasst werden.The pivot arms 8 in this case have the end walls 4 encompassing driver 16, along the pivot arms 8 by means of actuators 17, in illustrated embodiment of compressed air cylinder, between a release and a driving position are displaced. With these actuators 17 or with additional control devices to be provided, in addition, the Schwenkarmlänge can be adjusted and thus adapted to different box heights.

Den Schwenkarmen 8 gehört ein zur Kreisbogenführung 13 konzentrisches Zahnkranzsegment 18 zu, welches mit einer an den Stelltrieb 7 angeschlossenen und in einer Linearführung 18 geführten Zahnstange 19 kämmt. Mit einem linearen Verlagern der Zahnstange 19 mit dem Stelltrieb 7 in der Führung 18 wird der Schwenkarm 8 aus seiner Aufnahme- in seine Aufstellstellung verlagert. Genauso könnte das Zahnkranzsegment 1 natürlich auch über ein Zahnrad(segment) angetrieben werden.The pivoting arms 8 include a circular arc guide 13 concentric sprocket segment 18, which meshes with a connected to the actuator 7 and guided in a linear guide 18 rack 19. With a linear displacement of the rack 19 with the actuator 7 in the guide 18, the pivot arm 8 is moved from its receiving position to its erect position. Likewise, the sprocket segment 1 could of course also be driven by a gear (segment).

Dem Rahmen 5 gehören vorzugsweise eine nicht dargestellte Steuereinrichtung und weitere Stelltriebe zu, mit denen der Abstand V der einzelnen Schwenktriebe bzw. Schwenkeinrichtungen zueinander, sowie die Arbeitsbreite der Transporteinrichtung 9 und dergleichen automatisiert an verschiedenste Klappbehältergrößen angepasst werden kann.The frame 5 preferably includes a control device, not shown, and further actuating drives, with which the distance V of each pivot drives or pivoting devices to each other, and the working width of the transport device 9 and the like can be automatically adapted to a variety of folding container sizes.
