Abhängige Vorrichtungsansprüche können hierbei mit dem Verfahren gemäß Anspruch 8 kombiniert werden.The present invention also provides a method having the features of claim 8. Dependent device claims can be combined with the method according to claim 8.

Ein Gedanke der vorliegenden Erfindung ist es hierbei, eine Vorrichtung bereitzustellen, die es ermöglicht, Verpackungsmaterialien unterschiedlicher Dimensionen individuell zu verarbeiten. Dennoch ermöglicht es die erfindungsgemäße Vorrichtung sowie das erfindungsgemäße Verfahren, einen relativ hohen Durchsatz zu realisieren.One idea of the present invention is to provide a device that enables packaging materials of different dimensions to be processed individually. Nevertheless, the device according to the invention and the method according to the invention make it possible to achieve a relatively high throughput.

Die erfindungsgemäße Vorrichtung und/oder das erfindungsgemäße Verfahren ist/sind zur Handhabung von "Verpackungsmaterial" geeignet. Der Begriff "Verpackungsmaterial" umfasst hierbei insbesondere Karton, der zunächst als Kartonzuschnitt vorliegt und durch die Vorrichtung oder das Verfahren weiterverarbeitet wird. Insbesondere ist es vorgesehen, aus dem Verpackungsmaterial, insbesondere dem Kartonzuschnitt, eine Box/ ein gefaltetes Verpackungsmaterial zur Aufnahme von Gegenständen zu formen.The device according to the invention and / or the method according to the invention is / are suitable for handling "packaging material". The term "packaging material" here includes in particular cardboard, which is initially available as a cardboard blank and is further processed by the device or the method. In particular, it is provided that a box / folded packaging material for receiving objects is formed from the packaging material, in particular the cardboard blank.

Ein Kartonzuschnitt als ein bevorzugtes Beispiel des Verpackungsmaterials kann dabei bereits mit ausgeschnitten Laschen ausgebildet sein. Ferner ist es möglich, dass die Falzlinien bereits eingebracht wurden.A cardboard blank as a preferred example of the packaging material can already be designed with tabs cut out. It is also possible that the fold lines have already been introduced.

"Breitenrichtung" oder "Breite" meint in Zusammenhang mit einer Falteinrichtung eine Richtung quer, insbesondere senkrecht, zu einer Durchlaufrichtung.“Width direction” or “width” in connection with a folding device means a direction transverse, in particular perpendicular, to a direction of passage.

Gemäß einer ersten Zielrichtung der vorliegenden Erfindung wird eine Vorrichtung zum Verarbeiten von Verpackungsmaterial, insbesondere Kartonzuschnitten, bereitgestellt, welche Vorrichtung umfasst: eine erste Falteinrichtung zum Falten und/oder Falzen des Verpackungsmaterials und eine zweite Falteinrichtung zum Falten und/oder Falzen des Verpackungsmaterials. Insbesondere sind die erste Falteinrichtung und die zweite Falteinrichtung in einer Durchlaufrichtung nacheinander angeordnet.According to a first aspect of the present invention, a device for processing packaging material, in particular cardboard blanks, is provided, which device comprises: a first folding device for folding and / or folding the packaging material and a second folding device for folding and / or folding the packaging material. In particular, the first folding device and the second folding device are arranged one after the other in a passage direction.

Ferner umfasst die Vorrichtung zumindest eine Transporteinrichtung zum Transportieren eines Verpackungsmaterials (bevorzugt in einer Durchlaufrichtung) relativ zur ersten und zweiten Falteinrichtung. Die Transporteinrichtung kann, wie nachfolgend beschriebenen, eine Transporteinrichtung sein, die das Verpackungsmaterial von einer Unterseite greift (Saugnapf/Saugnäpfe). Auch kann die Transporteinrichtung gemäß einer weiteren Alternative einen Roboterarm betreffen, der das Verpackungsmaterial relativ zur ersten und/oder zweiten Falteinrichtung, insbesondere von der ersten zur zweiten Falteinrichtung, bewegt.Furthermore, the device comprises at least one transport device for transporting a packaging material (preferably in a passage direction) relative to the first and second folding device. As described below, the transport device can be a transport device which grips the packaging material from an underside (suction cup / suction cups). According to a further alternative, the transport device can also relate to a robot arm that moves the packaging material relative to the first and / or second folding device, in particular from the first to the second folding device.

Die beschriebene Vorrichtung zeichnet sich dadurch aus, dass die erste und zweite Falteinrichtung unabhängig voneinander, insbesondere quer zu einer Durchlaufrichtung, verstellbar sind.The device described is characterized in that the first and second folding devices can be adjusted independently of one another, in particular transversely to a direction of passage.

Die Erfindung zeichnet sich ferner dadurch aus, dass die Vorrichtung eine Steuereinrichtung aufweist, die eingerichtet ist, die erste Falteinrichtung quer zur Durchlaufrichtung zu verstellen, während die zweite Falteinrichtung ein Verpackungsmaterial verarbeitet. Somit werden Stillstandzeiten vermieden und ein hoher Durchsatz bei hoher Flexibilität ermöglicht.The invention is further characterized in that the device has a control device which is set up to adjust the first folding device transversely to the direction of passage while the second folding device is processing a packaging material. This avoids downtimes and enables high throughput with high flexibility.

Mit "verstellbar" ist bevorzugt gemeint, dass die erste und die zweite Falteinrichtung unabhängig voneinander an eine Abmessung eines zu faltenden und/oder zu falzenden Verpackungsmaterials anpassbar sind."Adjustable" preferably means that the first and the second folding device can be adapted independently of one another to a dimension of a packaging material to be folded and / or folded.

In einer weiter bevorzugten Ausführungsform sind die Falteinrichtungen senkrecht zu einer Durchlaufrichtung verstellbar.In a further preferred embodiment, the folding devices can be adjusted perpendicular to a direction of passage.

Die Durchlaufrichtung kann eine geradlinige oder gekrümmte Richtung sein.The direction of passage can be a straight line or a curved direction.

Da die zuvor beschriebenen Falteinrichtungen unabhängig voneinander verstellbar sind, ist die Vorrichtung für Verpackungsmaterialien oder hieraus hergestellte Boxen unterschiedlicher Größen, insbesondere Breite, besonders flexibel einsetzbar. Somit ist es möglich, mit einer Vorrichtung Boxen unterschiedlicher Breite herzustellen, ohne dass aufwendige Rüstarbeiten notwendig sind oder der Herstellungsprozess angehalten werden müsste.Since the folding devices described above can be adjusted independently of one another, the device can be used particularly flexibly for packaging materials or boxes of different sizes, in particular widths, made from them. It is thus possible to produce boxes of different widths with one device without that complex set-up work is necessary or the manufacturing process would have to be stopped.

Die zweite Falteinrichtung kann an die zu faltende und/oder zu falzende Abmessung des Verpackungsmaterials anpassbar und die erste Falteinrichtung (40) an eine zu faltende und/oder zu falzende Abmessung eines in der Verarbeitung nachfolgenden Verpackungsmaterials anpassbar sein.The second folding device can be adaptable to the dimensions of the packaging material to be folded and / or folded, and the first folding device (40) can be adapted to a dimension to be folded and / or folded of a packaging material that is to be processed.

Es ist bevorzugt, dass die erste und/oder zweite Falteinrichtung jeweils zumindest ein Faltelement aufweist/aufweisen, bevorzugt zwei oder mehr Faltelemente, wobei das zumindest eine Faltelement, bevorzugt quer zur Durchlaufrichtung, verstellbar ist/sind, um die erste und/oder zweite Falteinrichtung zu verstellen. Beispielsweise kann es sich bei dem Faltelement um ein hochklappbares Faltelement handeln, oder im Falle mehrerer Faltelemente, um hochklappbare Faltelemente. Durch die Verstellbarkeit ist die beanspruchte Vorrichtung besonders flexibel.It is preferred that the first and / or second folding device each have at least one folding element, preferably two or more folding elements, wherein the at least one folding element is / are adjustable, preferably transversely to the direction of passage, around the first and / or second folding device to adjust. For example, the folding element can be a folding element that can be folded up, or in the case of several folding elements, folding elements that can be folded up. Due to the adjustability, the claimed device is particularly flexible.

Insbesondere weisen die erste und/oder zweite Falteinrichtung Träger auf, an denen jeweils ein Faltelement angebracht ist, wobei die Träger quer zur Durchlaufrichtung verstellbar sind. Somit wird ein flexibler und robuster Aufbau bereitgestellt.In particular, the first and / or second folding device have supports on each of which a folding element is attached, the supports being adjustable transversely to the direction of passage. A flexible and robust structure is thus provided.

Es ist bevorzugt, dass die Faltelemente oder Träger relativ zu einer in Durchlaufrichtung verlaufenden Mittenachse, insbesondere gleichzeitig, verfahrbar sind. Die mittige Ausrichtung gestattet es, Verpackungsmaterial verschiedener Dimensionen in vorteilhafter Weise zu verarbeiten.It is preferred that the folding elements or carriers can be moved relative to a central axis running in the direction of passage, in particular at the same time. The central alignment allows packaging material of different dimensions to be processed in an advantageous manner.

Es ist bevorzugt, dass die Vorrichtung eine erste Transporteinrichtung und eine zweite Transporteinrichtung umfasst, die derart angeordnet sind, dass das Verpackungsmaterial nach einem Transportieren mit der ersten Transporteinrichtung von der zweiten Transporteinrichtung übernommen werden kann. Auf diese Weise kann der Durchsatz erhöht werden.It is preferred that the device comprises a first transport device and a second transport device, which are arranged in such a way that the packaging material after being transported with the first transport device from the second transport device can be taken over. In this way the throughput can be increased.

Gemäß einer Ausführungsform ist es vorgesehen, dass die erste Transporteinrichtung eingerichtet ist, das Verpackungsmaterial zumindest abschnittsweise entlang der ersten Falteinrichtung zu transportieren, und die zweite Transporteinrichtung eingerichtet ist, das Verpackungsmaterial zumindest abschnittsweise entlang der zweiten Falteinrichtung zu transportieren. Somit kann ein hoher Verarbeitungstakt ermöglicht werden.According to one embodiment, it is provided that the first transport device is set up to transport the packaging material at least in sections along the first folding device, and the second transport device is set up to transport the packaging material at least in sections along the second folding device. A high processing rate can thus be made possible.

Es ist bevorzugt, dass die erste Transporteinrichtung und/oder die zweite Transporteinrichtung derart angeordnet sind, dass das Verpackungsmaterial beim Transportieren in Breitenrichtung im Wesentlichen mittig erfasst wird. Die mittige Ausrichtung gestattet es, Verpackungsmaterial verschiedener Dimensionen in vorteilhafter Weise zu verarbeiten.It is preferred that the first transport device and / or the second transport device are arranged in such a way that the packaging material is gripped essentially centrally in the width direction during transport. The central alignment allows packaging material of different dimensions to be processed in an advantageous manner.

Ferner ist es bevorzugt, dass die zumindest eine Transporteinrichtung, bevorzugt die erste Transporteinrichtung und/oder die zweite Transporteinrichtung, eingerichtet ist, das Verpackungsmaterial von einer Unterseite zu greifen.Furthermore, it is preferred that the at least one transport device, preferably the first transport device and / or the second transport device, is set up to grip the packaging material from an underside.

Die Vorrichtung kann eine Entnahmeeinheit umfassen, (die in Durchlaufrichtung nachrangig zur zweiten Falteinrichtung angeordnet ist,) wobei die Entnahmeeinheit bevorzugt eingerichtet ist, das Verpackungsmaterial gegen eine quer zur Durchlaufrichtung ausgerichtete, feststehende Ausrichteinrichtung zu bewegen, insbesondere zu schieben. Bezüglich der Vorteile einer solchen Entnahmeeinheit wird auf die nachfolgenden Erläuterungen verwiesen.The device can comprise a removal unit (which is arranged subordinate to the second folding device in the flow direction), wherein the removal unit is preferably set up to move, in particular to push, the packaging material against a stationary alignment device oriented transversely to the flow direction. With regard to the advantages of such a removal unit, reference is made to the following explanations.

Ferner kann es vorgesehen sein, dass, insbesondere benachbart zur Entnahmeeinheit, eine Transportvorrichtung vorgesehen ist, insbesondere ein Förderband oder Riemenförderer angeordnet ist, und die Entnahmeeinheit eingerichtet ist, das Verpackungsmaterial an wählbaren Positionen auf die Transportvorrichtung abzulegen.Furthermore, it can be provided that, in particular adjacent to the removal unit, a transport device is provided, in particular a conveyor belt or belt conveyor is arranged, and the removal unit is set up to deposit the packaging material at selectable positions on the transport device.

Die Vorrichtung kann derart ausgebildet sein, dass die Transportvorrichtung mit einer konstanten Geschwindigkeit bewegt wird, und eine Steuereinrichtung eingerichtet ist, die Ablageposition des Verpackungsmaterials auf der Transportvorrichtung derart zu wählen, dass die Lücke zwischen aufeinanderfolgenden Verpackungsmaterialien gleich oder im Wesentlichen gleich bleibt.The device can be designed such that the transport device is moved at a constant speed, and a control device is set up to select the storage position of the packaging material on the transport device such that the gap between successive packaging materials remains the same or essentially the same.

Ferner betrifft die vorliegende Erfindung ein Verfahren, welches bevorzugt eine Vorrichtung gemäß einer der zuvor genannten Aspekte einsetzt. Das Verfahren umfasst dabei die Schritte: Bewegen eines Verpackungsmaterials zu einer ersten Falteinrichtung und Falten und/oder Falzen des Verpackungsmaterials mit der ersten Falteinrichtung, und Bewegen des Verpackungsmaterials zu einer zweiten Falteinrichtung und Falten und/oder Falzen des Verpackungsmaterials mit der zweiten Falteinrichtung. Dabei wird die erste Falteinrichtung, bevorzugt quer zur Durchlaufrichtung des Verpackungsmaterials, verstellt, während das Verpackungsmaterial zur zweiten Falteinrichtung bewegt oder mit dieser gefaltet wird. Es ist bevorzugt, dass die erste und die zweite Falteinrichtung unabhängig voneinander an eine Abmessung eines zu faltenden und/oder zu falzenden Verpackungsmaterials anpassbar sind.The present invention also relates to a method which preferably uses a device according to one of the aforementioned aspects. The method comprises the steps of moving a packaging material to a first folding device and folding and / or folding the packaging material with the first folding device, and moving the packaging material to a second folding device and folding and / or folding the packaging material with the second folding device. The first folding device is adjusted, preferably transversely to the direction of passage of the packaging material, while the packaging material is moved to the second folding device or is folded with it. It is preferred that the first and the second folding device can be adapted independently of one another to a dimension of a packaging material to be folded and / or folded.

Somit ist es möglich, mit Boxen unterschiedlicher Breite herzustellen, ohne dass der Herstellungsprozess angehalten werden müsste. Damit ist das Verfahren trotz der beschriebenen Flexibilität zu einer Herstellung mit hohem Durchsatz geeignet.It is thus possible to produce boxes of different widths without having to stop the production process. Thus, despite the flexibility described, the method is suitable for production with a high throughput.

Darüber hinaus kann die Erfindung eine Verwendung einer der zuvor genannten Vorrichtungen betreffen.In addition, the invention can relate to the use of one of the aforementioned devices.

Nachfolgend wird anhand der beigefügten Figuren eine bevorzugte Ausführungsform der vorliegenden Erfindung im Detail beschrieben. Weitere in diesem Zusammenhang genannte Modifikationen bestimmter Einzelmerkmale können jeweils miteinander kombiniert werden, um zusätzliche Ausführungsformen auszubilden.A preferred embodiment of the present invention is described in detail below with reference to the accompanying figures. Further modifications of certain individual features mentioned in this context can each be combined with one another in order to form additional embodiments.

In der in Fig. 1 gezeigten Draufsicht wird eine Ausführungsform der erfindungsgemäßen Vorrichtung dargestellt, welche mehrere Abschnitte aufweist. Insbesondere umfasst die Vorrichtung einen ersten Beschickungsbereich 10 sowie einen dem ersten Beschickungsbereich 10 gegenüberliegenden zweiten Beschickungsbereich 20. Gemäß einer Modifikation der vorliegenden Ausführungsform kann die Vorrichtung jedoch auch lediglich einen der Beschickungsbereiche aufweisen.In the in Fig. 1 The top view shown is an embodiment of the device according to the invention, which has several sections. In particular, the device comprises a first loading area 10 and a second loading area 20 opposite the first loading area 10 In a modification of the present embodiment, however, the device can also have only one of the loading areas.

Der erste Beschickungsbereich 10 und der zweite Beschickungsbereich 20 sind jeweils vorgesehen, Verpackungsmaterial (im vorliegenden Ausführungsbeispiel ein Kartonzuschnitt/Kartonzuschnitte) in einem jeweiligen Stapel M1, M2 aufzunehmen. Der Kartonzuschnitt kann vereinzelt und zu einer Übergabeeinrichtung 30 übergeben werden.The first loading area 10 and the second loading area 20 are each provided to receive packaging material (in the present exemplary embodiment a cardboard blank / cardboard blanks) in a respective stack M1, M2. The cardboard blank can be separated and transferred to a transfer device 30.

Über dem ersten Beschickungsbereich 10 erstreckt sich ein Portal 11, entlang dem, jeweils seitlich ausgerichtet, Aufnahmeeinheiten 12, 13 verfahrbar angeordnet sind. Die Aufnahmeeinheiten 12, 13 umfassen Aufnahmeeinrichtungen wie Saugnäpfe, welche in vertikaler Richtung nach unten ausgerichtet sind und einen Kartonzuschnitt, der sich auf dem Stapel M1 befindet, von oben zu greifen.A portal 11 extends over the first loading area 10, along which, in each case laterally aligned, receiving units 12, 13 are movably arranged. The receiving units 12, 13 comprise receiving devices such as suction cups, which are oriented vertically downwards and which grip a cardboard blank located on the stack M1 from above.

Mit den Aufnahmeeinheiten 12, 13 können jeweils abwechselnd Kartonzuschnitte vom ersten Stapel M1 aufgenommen und zu einer später detaillierter beschriebenen Übergabevorrichtung 30 bewegt werden (siehe Pfeil 1). Während eine der Aufnahmeeinheiten einen Kartonzuschnitt in Richtung der Übergabeeinrichtung 30 bewegt, kann die jeweils andere Aufnahmeeinheit von der Übergabeeinrichtung 30 in einen Bereich oberhalb des Stapels M1 bewegt werden.The receiving units 12, 13 can alternately pick up cardboard blanks from the first stack M1 and move them to a transfer device 30, which will be described in more detail later (see arrow 1). While one of the receiving units is moving a carton blank in the direction of the transfer device 30, the other receiving unit can be moved by the transfer device 30 into an area above the stack M1.

Das Portal 11 erstreckt sich ferner über den zweiten Beschickungsbereich 20. Die Aufnahmeeinheiten 12, 13 sind entlang des Portals 11 auch in den zweiten Beschickungsbereich verfahrbar. Somit können sowohl vom ersten Stapel M1 als auch vom zweiten Stapel M2 Verpackungsmaterialien entnommen werden.The portal 11 also extends over the second loading area 20. The receiving units 12, 13 can also be moved along the portal 11 into the second loading area. Packaging materials can thus be removed from both the first stack M1 and the second stack M2.

Am Portal 11 sind zwei Schutzwände 14, 15 angebracht, wobei sich eine erste Schutzwand 14 im Bereich des ersten Beschickungsbereichs 10 und eine zweite Schutzwand 15 im Bereich des zweiten Beschickungsbereichs 20 befindet. Die Schutzwände 14, 15 können entlang des Portals 11 verfahren werden und dienen als Schutzeinrichtung im Falle der Beschickung des ersten oder zweiten Beschickungsbereichs 10, 20 mit neuen Kartonzuschnitten. Hierfür kann die jeweilige Schutzwände 14, 15 in Richtung der Übergabeeinrichtung 30 verfahren werden, so dass eine Arbeiter nicht in den Bereich der Übergabeeinrichtung 30 gelangen kann.Two protective walls 14, 15 are attached to the portal 11, with a first protective wall 14 in the area of the first Loading area 10 and a second protective wall 15 is located in the area of the second loading area 20. The protective walls 14, 15 can be moved along the portal 11 and serve as a protective device in the event that the first or second loading area 10, 20 is loaded with new cardboard blanks. For this purpose, the respective protective walls 14, 15 can be moved in the direction of the transfer device 30 so that a worker cannot get into the area of the transfer device 30.

Die Aufnahmeeinheiten 12, 13 erfassen Kartonzuschnitte des ersten oder zweiten Stapels M1, M2 in einem Randbereich der Kartonzuschnitte, so dass die in Fig. 1 dargestellte Stellung der Schutzwände 14, 15 den Betrieb der Aufnahmeeinheiten 12, 13 nicht beeinträchtigt.The receiving units 12, 13 capture cardboard blanks of the first or second stack M1, M2 in an edge region of the cardboard blanks, so that the in Fig. 1 The position shown of the protective walls 14, 15 does not affect the operation of the receiving units 12, 13.

Die Übergabeeinrichtung 30 umfasst einen Auflagetisch 31, der sich quer, insbesondere senkrecht, zum Portal 11 erstreckt. Der Auflagetisch 31 der Übergabevorrichtung 30 weist eine Vielzahl von Längsnuten 32 auf. Gemäß einer weiteren Ausführungsform kann der Auflagetisch 31 jedoch auch lediglich eine Längsnut 32 umfassen.The transfer device 30 comprises a support table 31 which extends transversely, in particular perpendicularly, to the portal 11. The support table 31 of the transfer device 30 has a multiplicity of longitudinal grooves 32. According to a further embodiment, the support table 31 can, however, also comprise only one longitudinal groove 32.

Durch die Längsnuten 32 können, ausgehend von der Unterseite des Auflagetisches 31, Krallen in vertikaler Richtung nach oben bewegt werden. Befinden sich die Krallen in einer angehobenen Position, sodass sich die Krallen abschnittsweise über die Auflagefläche des Auflagetisches 31 erstrecken, so können die Krallen bei einer Bewegung entlang der Längsnuten 32 einen Kartonzuschnitt, der zuvor auf den Auflagetisch 31 aufgelegt wurde, entlang des Auflagetisches 31 bewegen.Through the longitudinal grooves 32, starting from the underside of the support table 31, claws can be moved upwards in the vertical direction. If the claws are in a raised position so that the claws extend in sections over the support surface of the support table 31, the claws can move a cardboard blank that was previously placed on the support table 31 along the support table 31 when moving along the longitudinal grooves 32 .

Die Bewegung des Kartonzuschnitts entlang der Übergabeeinrichtung 30 erfolgt dabei derart, dass der Kartonzuschnitt nach einer Bewegung entlang des Auflagetisches 31 relativ zu einer Mittenachse X1 zentriert ausgerichtet ist.The movement of the carton blank along the transfer device 30 takes place in such a way that after a movement along the support table 31 the carton blank is centered relative to a central axis X1.

Die Mittenachse X1 ist eine imaginäre Achse, die sich quer, insbesondere senkrecht, zur Bewegungsrichtung des Kartonzuschnitts entlang des Auflagetisches 31 erstreckt und entlang der nachfolgend beschriebenen Falteinrichtungen 40, 50 verläuft.The center axis X1 is an imaginary axis which extends transversely, in particular perpendicularly, to the direction of movement of the carton blank along the support table 31 and runs along the folding devices 40, 50 described below.

Entlang der Mittenachse X1 befindet sich eine Führung, mittels der der Kartonzuschnitt entlang oder durch eine erste Falteinrichtung 40 und eine zweite Falteinrichtung 50 bewegt wird. Die Falteinrichtungen 40, 50 sind eingerichtet, unterschiedliche Faltoperationen am Kartonzuschnitt durchzuführen.A guide is located along the center axis X1, by means of which the carton blank is moved along or through a first folding device 40 and a second folding device 50. The folding devices 40, 50 are set up to carry out different folding operations on the carton blank.

Zur Bewegung des Kartonzuschnitts entlang der Mittenachse X1 umfasst die Vorrichtung eine erste Transporteinrichtung 60, mit der der Kartonzuschnitt von der Übergabeeinrichtung 30 übernommen und entlang oder durch die erste Falteinrichtung 40 bewegt wird.

Figure 3 FIG. 13 is a top plan view of a portion of the FIG Figure 1 device shown. The first folding device 40 and the second folding device 50 are provided in this area.

An einem Ständer 200 ist eine Führungsschiene 220 für die erste Transporteinrichtung 60 und die zweite Transporteinrichtung 70 vorgesehen, wobei sich die Führungsschiene 220 entlang der Mittenachse X1 erstreckt. Die Führungsschiene 220 ist am Ständer 200 fixiert, bspw. angeschraubt. Die erste und zweite Transporteinrichtung 60, 70 sind entlang der Führungsschiene 220 verfahrbar.A guide rail 220 for the first transport device 60 and the second transport device 70 is provided on a stand 200, the guide rail 220 extending along the central axis X1. The guide rail 220 is fixed, for example screwed, to the stand 200. The first and second transport devices 60, 70 can be moved along the guide rail 220.

Entlang einer gemeinsamen Führungsschiene 220 sind die erste Transporteinrichtung 60 und die zweite Transporteinrichtung 70 verfahrbar, wobei sich die erste Transporteinrichtung 60 im Bereich der in Fig. 3 nicht dargestellten Übergabeeinrichtung 30 befindet und somit in dieser Position einen Kartonzuschnitt übernehmen kann.The first transport device 60 and the second transport device 70 can be moved along a common guide rail 220, the first transport device 60 being in the area of the in Fig. 3 Transfer device 30, not shown, is located and can thus take over a carton blank in this position.

Die erste Transporteinrichtung 60 und die zweite Transporteinrichtung 70 können an parallel angeordneten Verfahrbahnen aneinander vorbeibewegt werden, so das sich deren Verfahrwege entlang der Mittenachse X1 überlappen können.The first transport device 60 and the second transport device 70 can be moved past one another on parallel travel paths so that their travel paths along the central axis X1 can overlap.

Die erste und zweite Falteinrichtung 40, 50 werden durch einen Ständer 200 aufgenommen. Der Ständer 200 umfasst mehrere quer zur Förderrichtung angeordnete Führungsschienen 201, 202, 203, welche die nachfolgend detaillierter beschriebene Verstellbarkeit der Falteinrichtungen 40, 50 gestatten oder führen. Ferner sind in der vorliegenden Ausführungsform zwei Antriebselemente 204, 205 vorgesehen.The first and second folding devices 40, 50 are received by a stand 200. The stand 200 comprises a plurality of guide rails 201, 202, 203 which are arranged transversely to the conveying direction and which allow or guide the adjustability of the folding devices 40, 50, which is described in more detail below. Furthermore, two drive elements 204, 205 are provided in the present embodiment.

Die Antriebselemente 204, 205 sind in der vorliegenden Ausführungsform als Zahnriemen ausgebildet.The drive elements 204, 205 are designed as toothed belts in the present embodiment.

Die erste Falteinrichtung 40 umfasst einen ersten Träger 42a und einen zweiten Träger 42b, die sich in einer zur Mittenachse X1 parallelen Richtung erstrecken. An den Trägern 42a, 42b ist die Aufrichteinrichtung 41 angebracht.The first folding device 40 comprises a first carrier 42a and a second carrier 42b, which extend in a direction parallel to the central axis X1. The erecting device 41 is attached to the carriers 42a, 42b.

Ferner ist an jedem Träger 42a, 42b ein Faltelement 45a, 45b der ersten Falteinrichtung 40 vorgesehen, die in vertikaler Richtung nach oben geklappt werden können (in Fig. 3 senkrecht zur Zeichnungsebene). Das Hochklappen erfolgt dabei entgegengesetzt zur Durchlaufrichtung. Werden die Faltelemente 45a, 45b nach oben geklappt, so kann eine Querseite des Kartonzuschnitts nach oben geklappt werden.Furthermore, a folding element 45a, 45b of the first folding device 40 is provided on each carrier 42a, 42b, which folding element 45a, 45b can be folded upwards in the vertical direction (in FIG Fig. 3 perpendicular to the plane of the drawing). The folding up takes place in the opposite direction to the direction of passage. If the folding elements 45a, 45b are folded up, a transverse side of the cardboard blank can be folded up.

Der erste Träger 42a und der zweite Träger 42b sind durch das Antriebselement 204 entlang der Führungsschienen 201, 202 bewegbar. Der Antrieb hierfür erfolgt mittels des Motors 210, der ebenfalls am Ständer 200 aufgenommen ist. Nachdem die Träger 42a, 42b jeweils mit dem Antriebselement 204 gekoppelt sind, erfolgt eine gleichzeitige Bewegung der Träger 42a, 42b relativ zur Mittenlinie X1 (oder zur Führungsschiene 220). Somit wird die Breite der Falteinrichtung 40 eingestellt.The first carrier 42a and the second carrier 42b can be moved along the guide rails 201, 202 by the drive element 204. The drive for this takes place by means of the motor 210, which is also accommodated on the stand 200. After the carriers 42a, 42b are each coupled to the drive element 204, the carriers 42a, 42b are simultaneously moved relative to the center line X1 (or to the guide rail 220). Thus, the width of the folding device 40 is adjusted.

Die zweite Falteinrichtung 50 umfasst ferner einen ersten Träger 52a und einen zweiten Träger 52b, die entlang der Führungsschiene 203 bewegbar sind.The second folding device 50 further comprises a first carrier 52a and a second carrier 52b, which can be moved along the guide rail 203.

Ferner umfasst die zweite Falteinrichtung 50 ein erstes Faltelement 55a und ein zweites Faltelement 55b, die jeweils an einem Träger 52a, 52b angebracht sind. Die Faltelemente 55a, 55b sind in vertikaler Richtung nach oben schwenkbar, wobei die Schwenkbewegung der Faltelemente 55a, 55b in Richtung der Durchlaufrichtung erfolgt, wohingegen die zuvor beschriebenen Faltelemente 45a, 45b der ersten Falteinrichtung 40 entgegen der Durchlaufrichtung verschwenkt werden.Furthermore, the second folding device 50 comprises a first folding element 55a and a second folding element 55b, which are each attached to a carrier 52a, 52b. The folding elements 55a, 55b can be pivoted upwards in the vertical direction, the pivoting movement of the folding elements 55a, 55b taking place in the direction of the passage direction, whereas the previously described folding elements 45a, 45b of the first Folding device 40 can be pivoted against the direction of passage.

Somit kann durch die erste Falteinrichtung 40 eine in Durchlaufrichtung vordere Querseite des Kartonzuschnitts aufgerichtet werden, wohingegen durch die zweite Falteinrichtung 50 eine hintere Querseite des Kartonzuschnitts aufgerichtet wird.Thus, the first folding device 40 can erect a front transverse side of the carton blank in the direction of passage, whereas the second folding device 50 erects a rear transverse side of the carton blank.

Der erste Träger 52a und der zweite Träger 52b können durch das Antriebselement 205 verstellt werden, sodass die Breite der zweiten Falteinrichtung 50 durch eine Bewegung der Träger 52a, 52b relativ zur Mittenachse X1 einstellbar ist. Das Antriebselement 205 wird dabei ähnlich wie das Antriebselement 204 durch einen in den Figuren nicht explizit gezeigten Motor angetrieben.The first carrier 52a and the second carrier 52b can be adjusted by the drive element 205, so that the width of the second folding device 50 can be adjusted by moving the carriers 52a, 52b relative to the central axis X1. The drive element 205 is driven similarly to the drive element 204 by a motor not explicitly shown in the figures.

Im Bereich der Entnahmeeinheit 80 befindet sich eine Transportvorrichtung 90, die gemäß der hier beschriebenen Ausführungsform ein Förderband ist. In der vorliegenden Ausführungsform sind als Transportvorrichtung 90 zwei hintereinander angeordnete Förderbänder vorgesehen, jedoch ist ersichtlich, dass die Anzahl der Förderbänder nicht auf eine bestimmte Anzahl beschränkt ist. Nachfolgend wird deshalb lediglich auf ein Förderband 90 Bezug genommen.In the area of the removal unit 80 there is a transport device 90 which, according to the embodiment described here, is a conveyor belt. In the present embodiment, two conveyor belts arranged one behind the other are provided as the transport device 90, but it can be seen that the number of conveyor belts is not limited to a specific number. In the following, therefore, reference will only be made to a conveyor belt 90.

Seitlich zum Förderband 90 ist ein Ausrichtlineal 100 vorgesehen, welches entlang einer Ausrichtachse X2 verläuft. Die Ausrichtachse X2 ist versetzt zur Mittenachse X1 vorgesehen.An alignment ruler 100 is provided to the side of the conveyor belt 90 and runs along an alignment axis X2. The alignment axis X2 is offset to the central axis X1.

Die Entnahmeeinheit 80 umfasst einen Längsträger 81, der sich seitlich zum Förderband 90 erstreckt, und zwar in einer zur Mittenachse X1 oder zur Ausrichtachse X2 parallelen Richtung. Der Längsträger 81 bildet eine Führung für einen Auslegerarm 82, der entlang des Längsträgers 81 verfahrbar ist. Der Auslegerarm erstreckt sich zumindest abschnittsweise über das Förderband 90, und zwar quer, insbesondere senkrecht, zur Erstreckungsrichtung des Längsträgers 81.The removal unit 80 comprises a longitudinal support 81 which extends laterally to the conveyor belt 90, specifically in a direction parallel to the central axis X1 or to the alignment axis X2. The longitudinal beam 81 forms a guide for a cantilever arm 82 which can be moved along the longitudinal beam 81. The extension arm extends at least in sections over the Conveyor belt 90, specifically transversely, in particular perpendicularly, to the direction in which the longitudinal beam 81 extends.

Der Auslegerarm 82 ist zusätzlich zu einer Bewegung entlang des Längsträgers auch quer, insbesondere senkrecht, hierzu verstellbar.In addition to moving along the longitudinal beam, the extension arm 82 can also be adjusted transversely, in particular perpendicularly, to this end.

An einem Endabschnitt des Auslegerarms 82 ist ein Aufnahmeelement 83 vorgesehen, welches sich in einer zum Längsträger 81 im Wesentlichen parallelen Richtung erstreckt. Das Aufnahmeelement 83 ist eingerichtet, eine Box B (einen durch die Aufrichteinrichtung 41 und die Falteinrichtungen 40, 50 umgeformten Kartonzuschnitt) an einer Seitenwand der Box B aufzunehmen und die Box B gegen das Ausrichtlineal 100 zu führen und/oder daran auszurichten. Hierzu weist das Aufnahmeelement 83 in der vorliegenden Ausführungsform mehrere Saugnäpfe auf, wobei die Aufnahmeelement 83 in einer Modifikation auch lediglich einen Saugnapf oder andere Aufnahmeelemente aufweisen kann, beispielsweise einen oder mehrere Greifer, Zangen, oder ähnliches.At one end section of the cantilever arm 82, a receiving element 83 is provided, which extends in a direction essentially parallel to the longitudinal beam 81. The receiving element 83 is set up to receive a box B (a cardboard blank formed by the erecting device 41 and the folding devices 40, 50) on a side wall of the box B and to guide the box B against the alignment ruler 100 and / or to align it therewith. For this purpose, the receiving element 83 in the present embodiment has several suction cups, wherein the receiving element 83 in a modification can also have only one suction cup or other receiving elements, for example one or more grippers, pliers, or the like.

In der vorliegenden Ausführungsform ist am Auslegerarms 82 an einer zum Aufnahmeelement 83 benachbarten Position ein Halteelement 84 vorgesehen, das ähnlich oder entsprechend wie das Aufnahmeelement 83 eingerichtet ist, eine Box B zu halten. Das Halteelement 84 ist allerdings quer, insbesondere senkrecht, zum Aufnahmeelement 83 weggeklappt. Wird das Halteelemente 84 ausgeklappt, erstreckt es sich in einer Richtung des Aufnahmeelements 83. Durch den kombinierten Einsatz können längere Boxen B gehalten werden.
Die Entnahmeeinheit 80 ist auf Grund der zuvor beschriebenen Ausgestaltung somit eingerichtet, insbesondere mittels dem Aufnahmeelement 83, eine Box B (einen durch die Aufrichteinrichtung 41 und die Falteinrichtungen 40, 50 umgeformten Kartonzuschnitt) an einer Seitenwand der Box B aufzunehmen und die Box B gegen das Ausrichtlineal 100 zu führen und/oder daran auszurichten.In the present embodiment, a holding element 84 is provided on the cantilever arm 82 at a position adjacent to the receiving element 83, which is set up in a manner similar to or corresponding to the receiving element 83 to hold a box B. The holding element 84 is, however, folded away transversely, in particular perpendicularly, to the receiving element 83. If the holding element 84 is folded out, it extends in a direction of the receiving element 83. Longer boxes B can be held by the combined insert.
Due to the configuration described above, the removal unit 80 is thus set up, in particular by means of the receiving element 83, to receive a box B (a cardboard blank formed by the erecting device 41 and the folding devices 40, 50) on a side wall of the box B and to hold the box B against the To guide alignment ruler 100 and / or to align with it.

Dabei kann die Bewegung der Entnahmeeinheit 80 in Richtung des Ausrichtlineals 100 entweder dadurch gesteuert werden, dass der Maschinensteuerung die Dimensionen der Box B bekannt sind, oder es wird ein Taster eingesetzt, der eine Bewegung der Entnahmeeinheit 80 in Richtung des Ausrichtlineals 100 beendet, wenn die Box B gegen das Ausrichtlineal 100 gedrückt wird.The movement of the removal unit 80 in the direction of the alignment ruler 100 can either be controlled by the fact that the machine control system knows the dimensions of the box B, or a button is used that ends a movement of the removal unit 80 in the direction of the alignment ruler 100 when the Box B is pressed against the alignment ruler 100.

Nachdem das seitlich angeordnete Ausrichtlineal 100 verwendet wird, können Boxen unterschiedlicher Dimensionen, insbesondere unterschiedlicher Breiten, ausgerichtet werden.After the laterally arranged alignment ruler 100 is used, boxes of different dimensions, in particular different widths, can be aligned.

Das Aufnahmeelement 83 der Entnahmeeinheit 80 hält die Box B solange, bis ein Befehl aus der Maschinensteuerung zur Freigabe der Box B erfolgt. Daraufhin kann die Box B mit dem Förderband 90 weiter transportiert werden. Nachdem die Freigabe der Box B ggf. verzögert durchgeführt wird, ist es möglich, die Lücken zwischen aufeinander folgenden Boxen B auf ein bestimmtes Maß einzustellen.The receiving element 83 of the removal unit 80 holds the box B until a command from the machine control to release the box B is issued. The box B can then be transported further with the conveyor belt 90. After the release of box B is carried out with a delay, if necessary, it is possible to set the gaps between successive boxes B to a certain extent.

Nachfolgend wird ein beispielhafter Verfahrensablauf gemäß der vorliegenden Ausführungsform beschrieben.An exemplary method sequence according to the present embodiment is described below.

Zunächst wird in einem ersten Verfahrensschritt entweder vom Stapel M1 oder vom Stapel M2 ein Kartonzuschnitt entnommen und zur Übergabeeinrichtung 30 bewegt (Schritt S1). Hierbei wird der Kartonzuschnitt durch Saugnäpfe einer der Aufnahmeeinheiten 12, 13 von oben gegriffen und auf den Auflagetisch 31 der Übergabeeinrichtung 30 gezogen.First, in a first method step, a carton blank is removed either from the stack M1 or from the stack M2 and moved to the transfer device 30 (step S1). Here, the cardboard blank is gripped from above by suction cups of one of the receiving units 12, 13 and pulled onto the support table 31 of the transfer device 30.

Nachdem der Kartonzuschnitt auf dem Auflagetisch 31 der Übergabeeinrichtung 30 aufgelegt wurde, werden Krallen durch die Längsnuten 32 des Auflagetischs 31 nach oben bewegt. Nachfolgend werden die Krallen entlang der Längsnuten 32 verfahren, und somit der auf dem Auflagetisch 31 befindliche Kartonzuschnitt entlang der Übergabeeinrichtung 30 bewegt (Schritt 2). Hierbei wird der Kartonzuschnitt derart verfahren, dass dieser mittig zur Mittenachse X1 angeordnet ist.After the cardboard blank has been placed on the support table 31 of the transfer device 30, claws are moved upwards through the longitudinal grooves 32 of the support table 31. The claws are then moved along the longitudinal grooves 32, and thus the cardboard blank located on the support table 31 is moved along the transfer device 30 (Step 2). Here, the cardboard blank is moved in such a way that it is arranged in the middle of the center axis X1.

Die Krallen können nunmehr wieder abgesenkt und in Richtung des Portals 11 zurück bewegt werden. Dort können die Krallen einen weiteren Kartonzuschnitt übernehmen.The claws can now be lowered again and moved back in the direction of the portal 11. There the claws can take on another cardboard cut.

Der an der Mittenachse X1 ausgerichteten Kartonzuschnitt wird nunmehr von einer ersten Transporteinrichtung 60 übernommen und entlang der Mittenachse X1 bewegt (Schritt S3). Die Bewegung des Kartonzuschnitts erfolgt hierbei bis zur ersten Falteinrichtung 40. Im Zuge der Bewegung mit der ersten Transporteinrichtung 60 wird der Kartonzuschnitt durch die Aufrichteinrichtung 41 entlang von Faltlinien umgeformt. Somit umfasst der zu einer Box zu formende Kartonzuschnitt nunmehr einen Boden und zwei Längsseitenwände.The carton blank aligned on the central axis X1 is now taken over by a first transport device 60 and moved along the central axis X1 (step S3). The carton blank is moved up to the first folding device 40. In the course of the movement with the first transport device 60, the carton blank is reshaped by the erecting device 41 along fold lines. Thus, the cardboard blank to be formed into a box now comprises a base and two longitudinal side walls.

Durch die erste Falteinrichtung 40 wird eine erste Querseite des Kartonzuschnitts hochgeklappt (Schritt S4), so dass der zu einer Box zu formende Kartonzuschnitt zusätzlich eine (in Bewegungsrichtung vordere) Querseitenwand aufweist.A first transverse side of the carton blank is folded up by the first folding device 40 (step S4), so that the carton blank to be formed into a box additionally has a transverse side wall (front in the direction of movement).

Nachfolgend wird der Kartonzuschnitt von der zweiten Transporteinrichtung 70 übernommen und weiter entlang der Mittenachse X1 bewegt (Schritt S5). Hierbei gelangt der Kartonzuschnitt in den Bereich der zweiten Falteinrichtung 50, mit der eine zweite (in Durchlaufrichtung hintere) Querseite des Verpackungsmaterials hochgeklappt wird (Schritt S6) .The cardboard blank is then taken over by the second transport device 70 and moved further along the central axis X1 (step S5). Here, the cardboard blank arrives in the area of the second folding device 50, with which a second transverse side of the packaging material (at the rear in the direction of passage) is folded up (step S6).

Somit umfasst der zu einer Box zu formende Kartonzuschnitt nunmehr einen Boden, zwei Längsseitenwände und zwei Querseitenwände. Der Deckel des Verpackungsmaterials steht in vertikaler Richtung hoch.Thus, the cardboard blank to be formed into a box now comprises a base, two longitudinal side walls and two transverse side walls. The lid of the packaging material stands up in the vertical direction.

Nachfolgend wird die Box durch die Entnahmeeinheit 80 entnommen. Im Bereich der Entnahmeeinheit 80 wird der Kartonzuschnitt von der Entnahmeeinheit 80 aufgenommen und am Ausrichtlineal 100, das entlang der versetzt zur Mittenachse X1 angeordneten Ausrichtachse X2 verläuft, ausgerichtet und schließlich aus der Vorrichtung entnommen (Schritt S7).The box is then removed by the removal unit 80. In the area of the removal unit 80, the carton blank is picked up by the removal unit 80 and aligned on the alignment ruler 100, which runs along the alignment axis X2 offset from the central axis X1, and is finally removed from the device (step S7).

Dabei wird die Transportvorrichtung 90 mit einer konstanten Geschwindigkeit bewegt, und die Entnahmeeinheit 80 positioniert die Box B derart auf dem Förderband 90, dass die Lücke zwischen aufeinanderfolgenden Boxen B gleich oder im Wesentlichen gleich bleibt.The transport device 90 is moved at a constant speed and the removal unit 80 positions the box B on the conveyor belt 90 in such a way that the gap between successive boxes B remains the same or essentially the same.

Die bevorzugte Ausführungsform der vorliegenden Erfindung kann verwendet werden, um Verpackungsmaterial, wie Kartonzuschnitte, zu verarbeiten. Ein Kartonzuschnitt wird hierbei aus stabilisierten Papiersorten hergestellt.The preferred embodiment of the present invention can be used to process packaging materials such as cardboard blanks. A cardboard blank is made from stabilized types of paper.

Die aus Kartonzuschnitten hergestellten Boxen können zur Verpackung vielfältigster Produkte oder Waren zum Einsatz kommen. Die Dimensionen der Boxen unterscheiden sich, auch wenn im Bereich der Verpackungstechnik einige Einheitsgrößen bekannt sind.The boxes made from cardboard blanks can be used to pack a wide variety of products or goods. The dimensions of the boxes differ, even if some unit sizes are known in the field of packaging technology.

Da die zuvor beschriebenen Falteinrichtungen 40, 50 in der Breite (quer zur Durchlaufrichtung) verstellbar sind, ist die dargestellte Ausführungsform für Boxen unterschiedlicher Breite besonders flexibel einsetzbar. Mit anderen Worten ist es möglich, mit einer Maschine Boxen unterschiedlicher Breite herzustellen, ohne dass aufwendige Rüstarbeiten notwendig wären oder der Herstellungsprozess angehalten werden müsste.Since the previously described folding devices 40, 50 are adjustable in width (transverse to the direction of passage), the embodiment shown can be used particularly flexibly for boxes of different widths. In other words, it is possible to produce boxes of different widths with one machine without the need for complex set-up work or the production process having to be stopped.

Ferner ermöglicht die Entnahmeeinheit 80, die Ablageposition der Boxen/des Verpackungsmaterials auf der Transportvorrichtung 90 derart zu wählen, dass die Lücke zwischen aufeinanderfolgenden Verpackungsmaterialien gleich oder im Wesentlichen gleich bleibt. Somit ist die Ausführungsform gemäß dieser Zielrichtung für Boxen flexibel einsetzbar, die sich - in Durchlaufrichtung betrachtet - in ihren Dimensionen unterscheiden.Furthermore, the removal unit 80 enables the storage position of the boxes / packaging material on the transport device 90 to be selected such that the gap between successive packaging materials remains the same or essentially the same. So the Embodiment according to this objective can be used flexibly for boxes which - viewed in the direction of passage - differ in their dimensions.

Auch wenn die beschriebenen Falteinrichtungen 40, 50 und die Entnahmeeinheit 80 in der zuvor beschriebenen Ausführungsform bevorzugt zusammen zum Einsatz kommen, können die Falteinrichtungen 40, 50 und die Entnahmeeinheit 80 gemäß weiteren Modifikationen auch einzeln in einer Vorrichtung aufgenommen sein.Even if the described folding devices 40, 50 and the removal unit 80 are preferably used together in the embodiment described above, the folding devices 40, 50 and the removal unit 80 can also be accommodated individually in a device according to further modifications.
