Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Vorfalten von mit Falzen ausgerüsteten Folienverpackungen, insbesondere von Seitenfalzbeuteln für Schüttgüter, umfassend zumindest ein in die Folienverpackung einführbares Aufweitelement für die Verpackung.The invention relates to a device for pre-folding of foil packages equipped with folds, in particular of side fold bags for bulk goods, comprising at least one expansion element for the packaging which can be inserted into the foil package.
Folienverpackungen werden für die Aufnahme von Schüttgütern verwendet. Derartige Schüttgüter sind beispielsweise rieselfähige Gewürze, lose Tabakschnittmengen oder auch Produkte, die nicht für den Verzehr bzw. für einen Konsum geeignet sind. Damit eine derartige Folienverpackung ein größeres Volumen bereitstellen kann, werden ihre Seitenränder häufig mit Falzen versehen. Im Bereich eines Falzes liegt das Material der Folienverpackung in ihrem flachen Ausgangszustand mehrlagig vor. Ein Falz kann sich beispielsweise in einer Aufstellfläche einer derartigen Folienverpackung befinden. Auch an Seitenflächen werden Falze vorgesehen, diese sind regelmäßig nach innen zur Folienverpackungsmitte hin ausgerichtet.Foil packaging is used to hold bulk materials. Such bulk materials are, for example, free-flowing spices, loose amounts of tobacco or even products that are not suitable for consumption or for consumption. For such a film package to provide a larger volume, its side edges are often provided with folds. In the area of a fold, the material of the foil packaging is in multiple layers in its flat initial state. A fold can be located, for example, in a footprint of such a foil package. Folds are also provided on side surfaces, which are regularly aligned inwards towards the film packaging center.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung aufzuzeigen, mit der mit Falzen versehene Folienverpackungen insbesondere in einer Produktionsstraße zum Befüllen der Folienverpackungen definiert vorgefaltet werden können.The invention has for its object to provide a device of the type mentioned, can be prefilled defined with the folded film packages especially in a production line for filling the film packaging.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass das in die Folienverpackung einführbare Aufweitelement wenigstens ein Scheibenkörper ist, in dessen schmale umlaufende Kantenfläche eine nutförmige Vertiefung eingebracht ist und dass dem Aufweitelement Andrückkörper annäherbar zugeordnet sind, wobei die Andrückkörper in die Vertiefung vorstehbare und zur Vertiefung kongruent ausgeformte Abschnitte haben.This object is inventively achieved in that the insertable into the film wrap expander is at least one disk body, in the narrow circumferential edge surface a groove-shaped depression is introduced and that the expansion element Andrückkörper are associated with an approximate, the Andrückkörper protruding into the recess and congruent to recess formed Have sections.
Bei der erfindungsgemäßen Vorrichtung dient das Aufweitelement nicht nur dem Aufweiten der Folienverpackung beispielsweise vor Einfüllen von Schüttgütern in die Folienverpackung, sondern auch dem Vorfalten der mit Falzen ausgerüsteten Abschnitte. Da sich diese Abschnitte an den Rändern der Folienverpackung befinden, werden konstruktive Maßnahmen in der umlaufenden Kantenfläche des als Scheibenkörper ausgebildeten Aufweitelementes vorgenommen. Das Aufweitelement ist ein Scheibenkörper, daher ist seine flächige Erstreckung größer als seine umlaufende Kantenfläche. Diese Kantenfläche wird aber beim Einführen des Aufweitelementes den Rändern der Verpackung zugeordnet.In the device according to the invention, the expansion element serves not only the expansion of the film packaging, for example, before filling bulk materials in the film packaging, but also the pre-folding of the equipped with folding sections. Since these sections are located at the edges of the film packaging, constructive measures are taken in the peripheral edge surface of the expander formed as a disk body. The expansion element is a disk body, so its areal extent is greater than its peripheral edge surface. However, this edge surface is assigned to the edges of the packaging during insertion of the expansion element.
Nach der Erfindung ist in der umlaufenden Kantenfläche eine Vertiefung vorhanden und es sind weiterhin Andrückkörper vorhanden, welche in die Vertiefung einführbare Abschnitte aufweisen. Diese Abschnitte sind kongruent zur Vertiefung ausgebildet, das bedeutet, dass diese Abschnitte formschlussartig in die Vertiefung eingeführt werden. Nach dem Einführen des Aufweitelementes in die Verpackung sind Verpackungsabschnitte zwischen Vertiefung und Abschnitten der Andrückkörper angeordnet, sie werden also von den Andrückkörpern in die Vertiefung zwangsgeführt. Dabei erfolgt ein Vorfalten, ein sogenanntes Brechen der mit Falzen ausgerüsteten Abschnitte der Folienverpackung.According to the invention, a recess is present in the peripheral edge surface and there are further Andrückkörper available which have insertable sections in the recess. These sections are congruent with the recess, which means that these sections are inserted into the recess in a form-fitting manner. After insertion of the expansion element into the packaging packaging sections between the recess and portions of the Andrückkörper are arranged, so they are forcibly guided by the Andrückkörpern in the depression. In this case, there is a pre-folding, a so-called breaking the equipped with folding sections of the film packaging.
Aufweitelement und Andrückkörper bilden eine Art Presse für die mit Falzen ausgerüsteten Abschnitte der Verpackung aus. Durch die Vertiefung in der umlaufenden Kantenfläche des Aufweitelementes ist dabei sichergestellt, dass die Randabschnitte der Verpackung in die Vertiefung hinein nach innen zur Mitte der Verpackung geführt werden. Dadurch wird die später gewünschte Faltung nach innen sicher ausgebildet.Expander element and pressing body form a kind of press for the sections of the packaging equipped with folds. By the recess in the peripheral edge surface of the expansion element is thereby ensured that the edge portions of the package in the recess inside to Center of the packaging to be performed. As a result, the later desired folding is formed securely inside.
Nach einer ersten Weiterbildung der Erfindung ist vorgesehen, dass das Aufweitelement aus zwei Scheibenkörpern ausgebildet ist, deren Abstand zueinander veränderbar ist. Beide Scheibenkörper sind regelmäßig in ein und derselben Ebene angeordnet, ihr Abstand kann verändert werden, um eine Anpassung an Folienverpackungen mit von einander verschiedenen Dimensionen, insbesondere von einander verschiedenen Innenbreiten zu ermöglichen. Nach einer Veränderung des Abstandes werden die Scheibenkörper festgelegt, dazu ist vorzugsweise eine Längsführung vorgesehen. Die Längsführung ist vorzugsweise zur Haltung des Aufweitelementes ausgelegt, dabei kann die Längsführung parallel zur Einführung des Aufweitelementes in die Folienverpackung verschiebbar sein. Aufgrund dieser Verschiebbarkeit ist ein Ein- und Herausführen des Aufweitelementes in die bzw. aus der Folienverpackung möglich. Nach dem Einführen in eine Folienverpackung ist zudem noch ein Stück weit eine Bewegung des Aufweitelementes in Richtung des Bodens der Folienverpackung einstellbar, dadurch wird eine im Bodenbereich der Folienverpackung angeordnete Falz vorgefaltet.According to a first development of the invention, it is provided that the expander element is formed from two disk bodies whose distance from one another can be changed. Both disk bodies are regularly arranged in one and the same plane, their distance can be changed to allow adaptation to film packaging with different dimensions, in particular of different inner widths. After a change in the distance, the disk body are fixed, this is preferably a longitudinal guide provided. The longitudinal guide is preferably designed for holding the expanding element, while the longitudinal guide can be displaced parallel to the introduction of the expansion element in the film package. Due to this displaceability, it is possible to feed in and out the expansion element into or out of the foil packaging. After insertion into a film packaging, a movement of the expansion element in the direction of the bottom of the film packaging can also be adjusted to a certain extent, as a result of which a fold arranged in the bottom region of the film packaging is prefolded.
Eine konstruktive Ausbildung der Erfindung sieht vor, dass die Vertiefung in der umlaufenden Kantenfläche v-förmig ausgebildet ist. In das Tal des V kann ein Seitenabschnitt der Folienverpackung eingeführt werden und dadurch vorgefaltet werden.A structural design of the invention provides that the recess in the peripheral edge surface is V-shaped. In the valley of the V, a side portion of the film package can be introduced and thereby pre-folded.
Nach einer nächsten Weiterbildung der Erfindung ist vorgesehen, dass jeder Andrückkörper an der Längsführung schwenkbeweglich gehalten ist und von einem Schwenkantrieb beaufschlagt ist. Die Andrückkörper sind gleichfalls an der Längsführung gehalten, dadurch können sie dem Aufweitelement zugeordnet werden. Das Zuordnen erfolgt durch eine Annäherung auf einem Schwenkwege, die Andrückkörper sind dazu von einem Schwenkantrieb beaufschlagt. Vorzugsweise weist der Schwenkantrieb Hebelelemente auf, welche die Andrückkörper tragen.According to a next development of the invention, it is provided that each pressure body is held pivotably on the longitudinal guide and is acted upon by a pivot drive. The Andrückkörper are also held on the longitudinal guide, thereby they can be assigned to the expander. The assignment is made by approaching on a pivoting path, the Andrückkörper are acted upon by a pivot drive. Preferably, the pivot drive on lever elements which carry the Andrückkörper.
Die Vertiefung in der umlaufenden Kantenfläche ist vorzugsweise v-förmig ausgebildet. In diesem Fall sind die zur Vertiefung kongruent ausgeformten Abschnitte der Andrückkörper im Schnitt keilförmig ausgebildet, die Keilflächen der kongruent ausgeformten Abschnitte können sich an die entsprechenden Flächen der v-förmig ausgebildeten Vertiefung anlegen. Dazwischen befindet sich dann die vorzufaltende Kante der Folienverpackung.The recess in the peripheral edge surface is preferably V-shaped. In this case, the congruently shaped sections of the pressing bodies are wedge-shaped in section, the wedge surfaces of the congruently shaped sections can rest against the corresponding surfaces of the v-shaped recess. In between is then the prefolded edge of the foil packaging.
Für die Bewegung der Hebelelemente ist vorgesehen, dass an den Hebelarmen Führungsprofile angreifen, welche durch Kraftelemente beaufschlagt werden. Kraftelemente können beispielsweise Arbeitszylinder umfassen, welche eine Bewegung der Hebelelemente in der Weise bewirken, dass sich die Andrückkörper an das Aufweitelement annähern bzw. sich von diesem entfernen, wenn die Verpackung vorgefaltet wurde.For the movement of the lever elements is provided that attack on the lever arms guide profiles, which are acted upon by force elements. Force elements may, for example, comprise working cylinders which cause movement of the lever elements in such a way that the pressure bodies approach or move away from the expansion element when the packaging has been prefolded.
Als Kraftelemente für die Führungsprofile wie auch für die Längsführung des Aufweitelementes sind vorzugsweise Elektromotoren vorgesehen.As power elements for the guide profiles as well as for the longitudinal guidance of the expansion element electric motors are preferably provided.
Zur weiteren Ausbildung ist noch vorgesehen, dass das Aufweitelement und jeder Andrückkörper aus Metall gefertigt ist, welches die erforderliche Härte für das Aufbringen der Andrückkräfte hat.For further training is still provided that the expansion element and each pressure body is made of metal, which has the required hardness for the application of the pressing forces.
Schließlich ist nach einer Weiterbildung noch vorgesehen, dass die Vorrichtung insgesamt auswechselbar in eine Produktionsstraße zum versandfertigen Befüllen von Folienverpackungen mit Schüttgütern, insbesondere mit Tabak, einsetzbar ist. Das Einsetzen kann anhand entsprechend ausgebildeter Halterungen mit wenigen Handgriffen erfolgen. Bei dem Verpacken von Tabak sind neben Seitenfalzbeuteln auch andere Beutel üblich, beispielsweise Wickelbeutel. Die erfindungsgemäße Vorrichtung kann aufgrund ihrer einfachen Ein- und Ausbaubarkeit somit in eine Produktionsstraße eingesetzt werden, in welcher von einander verschiedene Tabakverpackungen befüllt und verschlossen werden können.Finally, according to a further development, it is provided that the device can be used interchangeably as a whole in a production line for the ready-to-fill filling of film packagings with bulk goods, in particular with tobacco. The insertion can be done with a few simple steps based on appropriately trained brackets. In the packaging of tobacco in addition to Seitenfalzbeuteln other bags are common, such as wrapper. The device according to the invention can thus be used in a production line, in which tobacco packaging different from each other can be filled and sealed due to their ease of installation and removal.
