Description

Technisches GebietTechnical field

Die vorliegende Erfindung betrifft ein Verfahren zum Falten von plattenförmigen Elementen, insbesondere von Kartonagen. Des weiteren betrifft die vorliegende Erfindung eine Vorrichtung zum Falten von plattenförmigen Elementen zur Durchführung des Verfahrens.The present invention relates to a method for folding of plate-shaped elements, especially cardboard. The present invention further relates to a Device for folding plate-shaped elements for Execution of the procedure.

Stand der TechnikState of the art

Plattenförmige Elemente, wie beispielsweise Kartonagen werden für vielfältige Zwecke verwendet, wie beispielsweise für das Verpacken von Gegenständen. Während des Verpackungsvorganges ist in der Regel ein Falten der Kartonagen erforderlich, um den zu verpackenden Gegenstand mit der Kartonage zu umschließen.
Im Stand der Technik sind Verfahren zum Falten von Kartonagen sowie entsprechende Vorrichtungen bekannt, bei denen benachbarte Kartonabschnitte entlang einer Faltkante gefaltet werden, wobei entlang der Faltkante feste oder bewegliche Gegendruckelemente anliegen und zumindest ein Kartonabschnitt um die Achse der Faltkante herum gebogen wird.
Diese bekannten Verfahren und Vorrichtungen zum Falten von Kartonagen besitzen zunächst den Nachteil, dass die Gegendruckelemente nach dem Faltvorgang im Inneren des gefalteten Elementes liegen und von dort entfernt werden müssen. Darüber hinaus müssen das zu faltende Element und/oder die Gegendruckelemente derart verfahren und gesteuert werden, dass sie während des Faltens aneinander anliegen, was eine erhöhte Komplexität des Verfahrens und der Vorrichtung zum Falten mit sich bringt.
Insbesondere bei einer hohen Anzahl an nacheinanderfolgenden Faltvorgängen werden diese häufig im Durchlaufbetrieb durchgeführt, d. h. die zu faltenden Gegenstände werden während des Faltvorganges nacheinander durch eine Faltvorrichtung geführt.
Allerdings ist im Durchlaufbetrieb die Anordnung von Gegendruckelementen besonders nachteilig, da die oben genannten Nachteile des Standes der Technik verstärkt werden und der reibungslose Durchlauf der zu faltenden Elemente durch die Gegendruckelemente behindert wird.Plate-shaped elements, such as cardboard boxes, are used for a variety of purposes, such as for packaging objects. During the packaging process, folding of the cardboard boxes is usually necessary in order to enclose the object to be packed with the cardboard box.
Methods for folding cardboard boxes and corresponding devices are known in the prior art, in which adjacent cardboard sections are folded along a folding edge, fixed or movable counterpressure elements being present along the folding edge and at least one cardboard section being bent around the axis of the folding edge.
These known methods and devices for folding cardboard boxes initially have the disadvantage that the counterpressure elements lie inside the folded element after the folding process and have to be removed from there. In addition, the element to be folded and / or the counter-pressure elements must be moved and controlled in such a way that they abut against one another during the folding, which results in an increased complexity of the method and the device for folding.
Particularly when there are a large number of consecutive folding processes, these are often carried out in continuous operation, ie the objects to be folded are passed through a folding device one after the other during the folding process.
However, the arrangement of counterpressure elements is particularly disadvantageous in continuous operation, since the above-mentioned disadvantages of the prior art are amplified and the smooth passage of the elements to be folded is hindered by the counterpressure elements.

Darstellung der ErfindungPresentation of the invention

Der vorliegenden Erfindung liegt das technische Problem zugrunde, ein Verfahren zum Falten plattenförmiger Elemente, insbesondere von Kartonagen bereitzustellen, welches die genannten Nachteile des Standes der Technik, insbesondere im Durchlaufbetrieb, beseitigt und einfach durchzuführen ist.
Zusätzlich soll eine Vorrichtung zum Falten plattenförmiger Elemente, insbesondere von Kartonagen, bereitgestellt werden, die das Verfahren vorteilhaft ausgestaltet.The present invention is based on the technical problem of providing a method for folding plate-shaped elements, in particular cardboard boxes, which eliminates the disadvantages of the prior art, in particular in continuous operation, and is simple to carry out.
In addition, a device for folding plate-shaped elements, in particular cardboard boxes, is to be provided, which advantageously embodies the method.

Dieses technische Problem wird durch ein Verfahren zum Falten plattenförmiger Elemente nach Anspruch 1 sowie eine entsprechenden Vorrichtung nach Anspruch 5 gelöst, bei welchen dank der Erfindung auf störende Gegendruckelemente verzichtet werden kann.This technical problem is solved by a method of folding plate-shaped elements according to claim 1 and a corresponding device according to claim 5 solved at which thanks to the invention on disturbing counter pressure elements can be dispensed with.

Der vorliegenden Erfindung liegt der Gedanke zugrunde, dass die Kraftkomponente für den Abbiegevorgang an dem zu faltenden Abschnitt des plattenförmigen Elementes nicht durch separate, aufwändige Gegendruckelemente, sondern durch die Vertikalkomponente der Kontaktkraft zwischen der zweiten Druckvorrichtung und plattenförmigem Element ausgeglichen wird. Mit anderen Worten, dank des verbesserten Kraftangriffs der zweiten Druckvorrichtung an dem plattenförmigen Element kann bei der vorliegenden Erfindung auf die im Stand der Technik erforderlichen Gegendruckelemente entlang der Faltkante verzichtet werden.The present invention is based on the idea that the force component for the turning process on the not folding section of the plate-shaped element separate, complex counter pressure elements, but through the Vertical component of the contact force between the second Pressure device and plate-shaped element balanced becomes. In other words, thanks to the improved force attack the second printing device on the plate-shaped element can in the present invention to those in the prior art Technology required counter pressure elements along the Folding edge can be dispensed with.

Die mit der Erfindung erreichten Vorteile bestehen insbesondere darin, dass sich dank des Verzichtes auf Gegendruckelemente ein ungestörter Ablauf des Faltvorganges und eine vereinfachte Konstruktion und Steuerung der Faltvorrichtung ergeben. So müssen Gegendruckelement und Faltkante nicht mehr aneinander angelegt werden und es wird kein Gegendruckelement durch das Falten eingeschlossen. Diese Verbesserungen wirken sich besonders vorteilhaft auf Faltvorgänge im Durchlaufverfahren aus, da die plattenförmigen Elemente die Faltvorrichtung ohne Gegendruckelement ungehindert durchlaufen können.The advantages achieved with the invention exist especially that thanks to the waiver Counter pressure elements an undisturbed sequence of the folding process and simplified design and control of the Folding device result. So counter pressure element and Folded edges can no longer be put together and it will no counter pressure element enclosed by the folding. This Improvements are particularly beneficial Folding processes in the continuous process because the plate-shaped elements without the folding device Counter pressure element can pass through unhindered.

Nach einer ersten Weiterbildung der vorliegenden Erfindung wird die Faltkante der plattenförmigen Elemente als Falterleichterung, bevorzugt als Querschnittsverjüngung und/oder Perforation, erzeugt. Auf diese Weise wird die gewünschte Lage der Faltkante vordefiniert und die zum Falten erforderliche Kraft wird erheblich vermindert.After a first development of the present invention is the folded edge of the plate-shaped elements as Easier to fold, preferably as a cross-sectional taper and / or perforation. In this way the Predefined position of the folded edge and the position for folding required force is significantly reduced.

Insbesondere bei einer hohen Anzahl an nacheinanderfolgenden Faltvorgängen ist es vorteilhaft, das Falten gemäß einer Weiterbildung der vorliegenden Erfindung im Durchlaufverfahren durchzuführen. Dabei werden die zu faltenden plattenförmigen Elemente nacheinander in die Faltvorrichtung eingelegt und zum Falten durch diese hindurchgeführt. Dadurch ergibt sich ein kontinuierlicher Faltvorgang, was zu Zeit- und Kosteneinsparungen führt.Especially with a high number of consecutive ones Folding processes, it is advantageous to fold according to one Development of the present invention in Continuous process. In doing so, they become folding plate-shaped elements one after the other into the Folding device inserted and for folding by this passed. This results in a continuous Folding process, which leads to time and cost savings.

Um den Steuerungsaufwand des Faltverfahrens und den Konstruktionsaufwand der Faltvorrichtung zu vermindern, nimmt die zweite Druckvorrichtung gemäß einer Weiterbildung der Erfindung während des Faltens eine stationäre Position ein, an welcher der zweite Abschnitt der plattenförmigen Elemente entlanggeführt wird. Bei dieser Weiterbildung erfolgt das Falten des plattenförmigen Elementes nicht durch eine Bewegung der zweiten Druckvorrichtung, sondern durch die Bewegung des plattenförmigen Elementes. Besonders vorteilhaft ist diese Vorgehensweise im Durchlaufverfahren, da dann die Durchlaufbewegung des plattenförmigen Elementes durch die Faltvorrichtung gleichzeitig zur Ausführung des Faltvorganges genutzt wird.In order to control the folding process and the To reduce the design effort of the folding device takes the second printing device according to a development of the Invention during folding a stationary position, at which the second section of the plate-shaped elements is guided along. This is done with this training Do not fold the plate-shaped element by one Movement of the second printing device, but by the Movement of the plate-shaped element. Particularly advantageous is this procedure in the continuous process, because then the Continuous movement of the plate-shaped element through the Folding device at the same time as the folding process is being used.

Zur Erzeugung der zweiten Kraftkomponente in der Ebene des zweiten Abschnittes des plattenförmigen Elementes ist es vorteilhaft, gemäß einer weiteren Fortbildung der vorliegenden Erfindung Kontaktkräfte infolge Gleit- oder Haftreibung zwischen der zweiten Druckvorrichtung und dem zweiten Abschnitt der plattenförmigen Elemente auszunutzen.
Auf diese Weise sind keine besonderen Vorrichtungen, wie beispielsweise formschlüssige Kontaktelemente zwischen dem zweiten Abschnitt des plattenförmigen Elementes und der zweiten Druckvorrichtung erforderlich. Allerdings kann es auch sinnvoll sein, dass das plattenförmige Element während des Faltens durch die erste und/oder zweite Druckvorrichtung gehalten ist, beispielsweise durch Kraft- oder Formschluss.To generate the second force component in the plane of the second section of the plate-shaped element, it is advantageous according to a further development of the present invention to use contact forces due to sliding or static friction between the second pressure device and the second section of the plate-shaped elements.
In this way, no special devices, such as positive contact elements between the second portion of the plate-shaped element and the second printing device are required. However, it can also make sense for the plate-shaped element to be held by the first and / or second pressure device during folding, for example by a force fit or a form fit.

Um die Durchlaufbewegung der plattenförmigen Elemente beim Durchlaufverfahren zu erleichtern, weist die zweite Druckvorrichtung gemäß einer Weiterbildung der vorliegenden Erfindung zumindest eine Rolle auf, die beim Falten an dem zweiten Abschnitt des plattenförmigen Elementes anliegt. Besonders vorteilhaft ist diese Anordnung, wenn an der zweiten Druckvorrichtung mehrere in Durchlaufrichtung hintereinander angeordnete Rollen, die an dem zweiten Abschnitt des plattenförmigen Elementes anliegen, zu einem oder mehreren Rollensätzen zusammengefasst werden. Die Rollen oder Rollensätze führen das plattenförmige Element im Durchlaufverfahren durch die Faltvorrichtung und sind gleichzeitig derart angeordnet, dass der zweite Abschnitt des plattenförmigen Elementes durch die Rollen oder Rollensätze gefaltet wird.To the continuous movement of the plate-shaped elements when The second shows that continuous processing is easier Printing device according to a development of the present Invention at least one role in folding the second section of the plate-shaped element rests. This arrangement is particularly advantageous if at the second printing device several in the direction of flow one behind the other rolls on the second Section of the plate-shaped element bear to a or more than one set of roles. The roles or roller sets guide the plate-shaped element in the Pass through the folder and are simultaneously arranged such that the second section of the plate-shaped element by the rollers or roller sets is folded.

Zur Erreichung des erfindungsgemäßen Kraftangriffs der Rollen an dem zweiten Abschnitt des plattenförmigen Elementes ist die Ausrichtung der Rollen bzw. Rollensätze gegenüber dem plattenförmigen Element entscheidend. Nach einer Weiterbildung der vorliegenden Erfindung verlaufen die Achsen der Rollen beim Falten im wesentlichen parallel zu dem an der Rolle anliegenden zweiten Abschnitt des plattenförmigen Elementes. Gleichzeitig weisen die Achsen der Rollen gegenüber der Faltkante keinen rechten Winkel auf, d. h. die Rollen sind gegenüber der Durchlaufrichtung schräggestellt. Durch die Schrägstellung der Rollen laufen diese nicht lediglich entlang des zweiten Abschnitts der plattenförmigen Elemente, sondern es entsteht eine Reibungskraft zwischen den Rollen und dem zweiten Abschnitt, die erfindungsgemäß eine zweite Kraftkomponente erzeugt, welche in der Ebene des zweiten Abschnitts verläuft und in Richtung der Faltkante wirkt. Auf diese Weise wird der erste Abschnitt des plattenförmigen Elementes an die erste Druckvorrichtung gepresst.To achieve the force application of the rollers according to the invention on the second section of the plate-shaped element the alignment of the rollers or roller sets with respect to the plate-shaped element crucial. After a Further development of the present invention, the axes run the rollers when folded substantially parallel to that on the Roll adjacent second section of the plate-shaped Element. At the same time, the axes of the rollers point no right angle with respect to the fold edge, i.e. H. the Rollers are inclined in relation to the direction of flow. Due to the inclination of the rollers, they don't run only along the second section of the plate-shaped Elements, but there is a frictional force between the Rolls and the second section, the invention a generates second force component, which in the plane of second section runs and in the direction of the folded edge acts. In this way, the first section of the plate-shaped element to the first printing device pressed.

Die Höhe der Reibungskraft zwischen den Rollen und dem zweiten Abschnitt der plattenförmigen Elemente kann gemäß einer Weiterbildung der Erfindung nicht nur über die Anordnung der Rollen, sondern auch über die Auslegung der Laufflächen mit einem bestimmten Reibungsbeiwert gesteuert werden. Hierbei sind hohe Reibungsbeiwerte der Laufflächen, die beispielsweise aus Gummi bestehen können, bevorzugt, um ein ausreichendes Anpressen des plattenförmigen Elementes an die erste Druckvorrichtung zu gewährleisten.The amount of friction between the rollers and the second section of the plate-shaped elements can according to a development of the invention not only on the Arrangement of roles, but also on the interpretation of the Treads controlled with a certain coefficient of friction become. Here are high friction coefficients of the tread, which may be made of rubber, for example, to sufficient pressing of the plate-shaped element to ensure the first printing device.

Um die Ausrichtung der Rollen bzw. Rollensätze an die Randbedingen des Faltvorganges, beispielsweise die Geometrie des plattenförmigen Elementes oder den gewünschten Faltwinkel anpassen zu können, sind die Rollen um die Faltkante schwenkbar und/oder um eine Achse senkrecht zum zweiten Abschnitt drehbar. Hierdurch wird eine erhöhte Flexibilität der Faltvorrichtung erreicht.In order to align the rollers or roller sets to the Boundary conditions of the folding process, for example the geometry of the plate-shaped element or the desired folding angle to be able to adapt are the rolls around the folded edge pivotable and / or about an axis perpendicular to the second Section rotatable. This increases flexibility the folding device reached.

Weiterhin ist es zur Erleichterung der Durchlaufbewegung der plattenförmigen Elemente durch die Faltvorrichtung gemäß einer Weiterbildung der vorliegenden Erfindung von Vorteil, dass die erste Druckvorrichtung ebenfalls zumindest eine Rolle aufweist, die beim Falten an dem ersten Abschnitt anliegt.Furthermore, it is to facilitate the continuous movement of the plate-shaped elements according to the folding device a further development of the present invention is advantageous, that the first printing device also has at least one Has role that when folding on the first section is applied.
