Description

Die Erfindung betrifft einen Abroller, insbesondere für Folien, mit einem Gehäuse und mit in dem Gehäuse seitlich angeordneten Stegen.The invention relates to a dispenser, in particular for films, with a housing and with laterally arranged webs in the housing.

Abroller der eingangs genannten Art werden vielfach bei der Verpackung von Waren und Produkten aller Art eingesetzt, insbesondere dann, wenn es gilt, die Waren und Produkte mit Folien oder Papier zu verpacken.Dispensers of the type mentioned are often used in the packaging of goods and products of all kinds, especially when it comes to packaging the goods and products with films or paper.

Hierzu verfügen die aus dem Stand der Technik bekannten Abroller über ein Gehäuseteil, das auch den Bereich der Aufnahme- und Schneidvorrichtung mit umschließt. Das Gehäuseteil, das zumeist aus Kunststoff hergestellt ist, ist dabei so dimensioniert, dass es über die seitlichen Stirnseiten einer Rolle, beispielsweise einer Folienrolle, hinausreicht.For this purpose, known from the prior art dispensers have a housing part, which also encloses the area of the receiving and cutting device. The housing part, which is usually made of plastic, is dimensioned such that it extends beyond the lateral end faces of a roll, for example a film roll.

Die Abroller verfügen über einen Wickelkern, der seitlich über in den Wickelkern hineinragende Stege drehbar gelegt ist. Die vorbekannten Abroller verfügen hierzu zumeist an ihren beiden Stirnseiten über eine Scheibe, die mittig mit dem Steg verbunden ist, so dass durch Aufschieben des Wickelkernes auf die Stege die Rolle zwischen den beiden Stegen gehaltert wird.The dispensers have a winding core, which is laterally rotatable about protruding into the winding core webs. The previously known dispensers for this purpose usually have at their two end faces on a disc which is connected centrally with the web, so that by sliding the winding core on the webs, the role between the two webs is supported.

Abroller der eingangs genannten Art sind zudem vorderseitig mit einem Klappdeckel und Gleitschlitz versehen, der länger als die Breite des abzurollenden Produktes, beispielsweise eine Folie, ist bzw. der eine Länge aufweist, die mit der Breite des Produktes korrespondiert.Dispensers of the type mentioned above are also provided on the front side with a hinged lid and sliding slot which is longer than the width of the product to be unrolled, for example a film, or which has a length which corresponds to the width of the product.

Die Funktionsweise der Abroller der eingangs genannten Art gestaltet sich derart, dass, nachdem die Rolle in das Gehäuse eingelegt ist, ein Stück der Folienfahne je nach Bedarf (einhändig) herausgezogen wird, um das betreffende Stück der Folienfahne mittels der Schneidvorrichtung von der Rolle zu trennen. Hierzu wird der Klappdeckel heruntergedrückt, um eine saubere Abtrennung der Folie herbeizuführen.The operation of the dispenser of the aforementioned type is such that, after the roll is inserted into the housing, a piece of film tab is pulled out as needed (one-handed) to separate the relevant piece of film tab by means of the cutter from the roll , For this purpose, the hinged lid is depressed to bring about a clean separation of the film.

Hierbei dreht sich der Wickelkern um die Stege. Der Wickelkern wird dabei nahezu passgenau, d.h. mit einem gewissen Spiel, zwischen Wickelkern und Stege gehaltert.Here, the winding core rotates around the webs. The winding core is almost accurate fit, i. with a certain play, held between hub and webs.

Aus der US 3,991,878 A ist ein Abroller, insbesondere für eine Folie, mit einem Gehäuse und mit in dem Gehäuse seitlich angeordneten Stegen bekannt, wobei der Steg mit einem Aufnahmeelement versehen ist, dessen zu dem Steg korrespondierende Flächenabschnitte den Steg lösbar oder unlösbar umschließen und Aufnahmeflächen für das abzurollende Produkt aufweisen.From the US 3,991,878 A is a dispenser, in particular for a film, with a housing and laterally arranged in the housing webs known, wherein the web is provided with a receiving element whose corresponding to the web surface portions the web detachably or permanently separate and have receiving surfaces for the product to be unrolled ,

Derartige Gestaltungen sind auch aus der US 2003/178462 A1 , JP 63 105630 U , US 2008/098868 A1 , JP 2000 1009065 A und US 5,806,786 A bekannt.Such designs are also from the US 2003/178462 A1 . JP 63 105630 U . US 2008/098868 A1 . JP 2000 1009065 A and US 5,806,786 A known.

Es hat sich herausgestellt, dass Wickelkerne länderspezifische Durchmesser aufweisen können, die insbesondere bei im asiatischen und nordamerikanischen Raum verwendeten Abrollern größer als der Durchmesser der herkömmlichen Stege ist. Dies hat jedoch den Nachteil, dass zuviel Spiel zwischen Steg und Wickelkern gegeben ist, so dass die Drehbewegung des Kernes und somit das Abrollen beeinträchtigt wird.It has been found that winding cores may have country-specific diameters, which is greater than the diameter of the conventional webs, especially in Abrollern used in Asian and North American space. However, this has the disadvantage that there is too much play between web and winding core, so that the rotational movement of the core and thus the rolling is impaired.

Es ist deshalb Aufgabe der vorliegenden Erfindung, einen Abroller der eingangs genannten Art derart weiterzuentwickeln, dass die Funktionalität der Abroller auch bei größeren Wickelkernen bzw. größeren Rollen gewährleistet ist.It is therefore an object of the present invention to develop a dispenser of the type mentioned in such a way that the functionality of the dispenser is guaranteed even with larger hubs or larger roles.

Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved with the features of claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims.

Die Erfindung sieht vor, dass der Steg mit einem Aufnahmeelement versehen ist, dessen zu dem Steg korrespondierende Flächenabschnitte den Steg lösbar oder unlösbar umschließen und Aufnahmeflächen für das abzurollende Produkt aufweisen, wobei die Aufnahmeelemente bogenförmige Vorsprünge - ähnlich wie ein Schaufelrad - aufweisen.The invention provides that the web is provided with a receiving element whose surface sections corresponding to the web detachably or non-detachably surround the web and have receiving surfaces for the product to be unrolled, wherein the receiving elements arcuate projections - similar to a paddle wheel - have.

Grundlegende Idee der Erfindung ist es, den für die Aufnahme des abzurollenden Produktes bzw. Wickelkernes erforderlichen Durchmesser des Steges durch ein Ergänzungsstück, das einen herkömmlichen Steg umgibt und den Wickelkern bzw. das abzurollende Produkt aufnimmt, zu vergrößern.The basic idea of the invention is to increase the diameter of the web required for receiving the product or winding core to be unrolled by a supplementary piece which surrounds a conventional web and receives the winding core or the product to be unrolled.

Dieses Aufnahmeelement kann im Zuge einer Neuproduktion eines Abrollers einteilig mit einem herkömmlichen normierten Steg ausgebildet werden.This receiving element can be integrally formed with a conventional normalized web in the course of a new production of a unwinder.

Alternativ ist es aber auch möglich, durch gegenüber einem herkömmlichen Steg erfolgende axiale Relativverschiebung das Aufnahmeelement auf den Steg aufzuschieben, so dass das Aufnahmeelement auf dem Steg lösbar und flächig aufliegt.Alternatively, it is also possible to postpone the receiving element onto the web by taking place relative to a conventional web axial relative displacement, so that the receiving element rests on the web detachable and flat.

Der Vorteil der Erfindung ist es, dass der Durchmesser eines herkömmlichen Steges eines gängigen Abrollers von vornherein oder nachträglich erweitert werden kann, so dass ein Wickelkern bzw. ein abzurollendes Produkt auch an länderspezifische Durchmesser unabhängig von der Stegdicke angepasst werden kann.The advantage of the invention is that the diameter of a conventional web of a common unwinding can be extended from the outset or subsequently, so that a winding core or a product to be unrolled can also be adapted to country-specific diameter regardless of the web thickness.

Um eine Vielzahl von Papier- und Folienrollen unterschiedlicher Bemessung zu erfassen, ist es von Vorteil, dass das Gehäuse eine Länge zwischen 335 mm und 345 mm, vorzugsweise mindestens 340 mm, eine Breite zwischen 835 mm und 845 mm, vorzugsweise mindestens 840 mm, und eine Höhe zwischen 695 mm und 705 mm, vorzugsweise mindestens 700 mm, aufweist. Es hat sich herausgestellt, dass durch Wahl dieser Maße eine Vielzahl von Abrollern von unterschiedlichen Herstellern und Anbietern Verwendung finden können. Hierzu trägt auch bei, dass der Steg vorteilhafterweise eine Länge zwischen 14,5 mm und 15,5 mm, vorzugsweise 15 mm, und die Scheibe einen Durchmesser zwischen 44,5 mm und 45,5 mm, vorzugsweise 45 mm, aufweisen.To capture a variety of paper and film rolls of different design, it is advantageous that the housing has a length between 335 mm and 345 mm, preferably at least 340 mm, a width between 835 mm and 845 mm, preferably at least 840 mm, and a height between 695 mm and 705 mm, preferably at least 700 mm. It has been found that by choosing these dimensions, a large number of unwinders from different manufacturers and suppliers can be used. This is also contributed to that the web advantageously has a length between 14.5 mm and 15.5 mm, preferably 15 mm, and the disc has a diameter between 44.5 mm and 45.5 mm, preferably 45 mm.

Eine praktikable Variante der Erfindung sieht vor, dass das Aufnahmeelement eine Länge zwischen 9 mm und 10 mm, vorzugsweise 9,5 mm, aufweist, so dass der der Scheibe abgewandte Endbereich des Steges frei übersteht.A practicable variant of the invention provides that the receiving element has a length between 9 mm and 10 mm, preferably 9.5 mm, so that the end region of the web facing away from the disc protrudes freely.

Ein Element der Erfindung sieht vor, dass das Aufnahmeelement bogenförmige Vorsprünge - ähnlich wie ein Schaufelrad - aufweist. Die Vorsprünge können dabei aus Kunststoff sein, so dass die Vorsprünge biegsam sind und sich so auch geringfügigen Änderungen eines Durchmessers von Wickelkernen anpasst. Die Breite der Vorsprünge beträgt dabei vorzugsweise zwischen 9 mm und 10 mm, bevorzugt 9,5 mm.An element of the invention provides that the receiving element arcuate Projections - similar to a paddle wheel - has. The projections may be made of plastic, so that the projections are flexible and thus also adapts to minor changes in a diameter of winding cores. The width of the projections is preferably between 9 mm and 10 mm, preferably 9.5 mm.

Als probates Maß für den Durchmesser des Aufnahmeelementes, das eine Vielzahl von Papierrollen und Folienrollen aufnehmen kann, hat sich ein Durchmesser zwischen 30 mm und 40 mm, bevorzugt 35 mm, erwiesen.As a proven measure of the diameter of the receiving element, which can accommodate a variety of paper rolls and rolls of film, a diameter between 30 mm and 40 mm, preferably 35 mm, has proven.

Um einen leichten Gebrauch des Abrollers zu gewährleisten, sieht eine weitere praktikable Variante der Erfindung vor, dass die Scheibe und/oder der Steg und/oder das Aufnahmeelement lösbar miteinander verbunden sind. Hierdurch können auch unliebsame Schmutzstellen beseitigt werden, die sich beispielsweise im Übergangsbereich zwischen Steg und Scheibe befinden.In order to ensure easy use of the unwinder, provides another practical variant of the invention that the disc and / or the web and / or the receiving element are releasably connected together. This also unpleasant dirt spots can be eliminated, which are located for example in the transition region between the web and disc.

Im Folgenden wird die Erfindung anhand der Zeichnungen näher erläutert. Es zeigt in schematischer Darstellung:

Fig. 1a, 1b zeigen einen mit dem Bezugszeichen 1 versehenen Abroller. Fig. 1a, 1b show a provided with the reference numeral 1 dispenser.

Der Abroller 1 weist ein Gehäuse 2 auf, das oberseitig mit der lösbaren Abdeckung 4 versehen ist. Das aus Kunststoff hergestellte Gehäuse 2 ist so bemessen, dass auch größere Rollen 3 mit ihrem Wickelkern um das Aufnahmeelement 9 drehbar gelegt werden können. Das Gehäuse 2 weist eine Länge von ca. 340 mm, eine Breite von ca. 840 mm und eine Höhe von ca. 700 mm auf und ist so breit, dass es über die beiden Stirnseiten der Rolle 3 reicht.The dispenser 1 has a housing 2, which is provided on the upper side with the detachable cover 4. The housing 2 made of plastic is dimensioned such that Larger rollers 3 with its winding core around the receiving element 9 can be rotated. The housing 2 has a length of about 340 mm, a width of about 840 mm and a height of about 700 mm and is so wide that it extends over the two end faces of the roller 3.

An seiner Vorderseite verfügt das Gehäuse 2 über eine Schneidvorrichtung 5 in Gestalt einer Klinge und über einen Klappdeckel 6. Die in das Gehäuse 2 eingelegte Rolle 3 wird je nach Bedarf aus dem Gehäuse 2 herausgezogen, um mittels der Schneidvorrichtung 5 von der Rolle 3 getrennt zu werden. Dabei wird der Klappdeckel 3 heruntergedrückt, um eine saubere Abtrennung der auf der Rolle 3 aufgerollten Folie zu ermöglichen.At its front, the housing 2 has a cutting device 5 in the form of a blade and a hinged lid 6. The inserted into the housing 2 roller 3 is pulled out as needed from the housing 2 to separated by means of the cutting device 5 of the roller 3 become. In this case, the hinged lid 3 is depressed to allow a clean separation of the rolled on the roll 3 film.

Wie aus den Fig. 1a, 1b zudem hervorgeht, ist im Inneren des Gehäuses 2 an den beiden Stirnseiten 13 eine aus Kunststoff hergestellte und mit den Stirnseiten 13 verbundene Scheibe 7 angeordnet, die einteilig und in ihrer Mitte mit einem Steg 10 verbunden ist, der sich in das Innere des Gehäuses 2 erstreckt. Der Steg 10 weist eine Länge von ca. 15 mm auf und ist mit dem Aufnahmeelement 9 lösbar oder unlösbar verbunden.Like from the Fig. 1a, 1b In addition, it is apparent that inside the housing 2 at the two end faces 13 there is arranged a disk 7 made of plastic and connected to the end faces 13, which is connected in one piece and at its center to a web 10 which extends into the interior of the housing 2 , The web 10 has a length of about 15 mm and is releasably or permanently connected to the receiving element 9.

Die zu dem Steg 10 korrespondierenden Flächenabschnitte des Aufnahmeelementes 9, die in den Fig. 2 und 3 gezeigt sind und mit dem Bezugszeichen 14 versehen sind, umschließen den Steg 10.The corresponding to the web 10 surface portions of the receiving element 9, in the Fig. 2 and 3 are shown and are provided with the reference numeral 14, enclose the web 10th

Das in den Fig. 1a, 1b gezeigte Aufnahmeelement 9 verfügt über Außenflächen, die zumindest zum Teil Aufnahmeflächen 15 für die auf der Rolle 3 aufgerollte Folie bilden. Das Aufnahmeelement 9 weist eine Länge von ca. 9,5 mm und einen Durchmesser von ca. 35 mm auf, so dass auch die Rolle 3 mit einem größeren Wickelkern zwischen den beiden Aufnahmeelementen 9 sicher gehaltert wird. Die Aufnahmeelemente 9 sind folglich derart bemessen, dass sie sich flexibler und besser auch einer größeren Breite der Rolle 3 anpassen, so dass das Abrollen und Abschneiden der Folie verbessert wird.That in the Fig. 1a, 1b shown receiving element 9 has outer surfaces which form at least in part receiving surfaces 15 for the rolled-up on the roll 3 film. The receiving element 9 has a length of about 9.5 mm and a diameter of about 35 mm, so that the roller 3 is securely held with a larger winding core between the two receiving elements 9. The receiving elements 9 are thus dimensioned such that they adapt more flexibly and better to a larger width of the roller 3, so that the rolling and cutting of the film is improved.

Wie aus Fig. 2 ersichtlich ist, die einen Ausschnitt aus dem Inneren 8 des Gehäuses 2 zeigt, verfügt das Aufnahmeelement 9 des erfindungsgemäßen Abrollers 1 über bogenförmige Vorsprünge 12 - ähnlich wie ein Schaufelrad. Konvex ausgebildete Flächen der Vorsprünge 12 bilden die Aufnahmeflächen 15 für die in den Fig. 1a, 1b gezeigte Rolle 3.How out Fig. 2 it can be seen that a section of the interior 8 of the housing 2 shows, the receiving element 9 of the unwinder according to the invention 1 has arcuate projections 12 - similar to a paddle wheel. Convex trained surfaces of the projections 12 form the receiving surfaces 15 for in the Fig. 1a, 1b shown roll 3.

Die in Fig. 2 gezeigten Vorsprünge 12 sind aus Kunststoff hergestellt und weisen eine gewisse Elastizität auf, so dass auch Rollen mit Wickelkern, die leicht unterschiedliche Durchmesser aufweisen, von dem Aufnahmeelement 9 aufgenommen und so gehaltert werden können. Wie aus Fig. 2 weiter hervorgeht, steht der von der Scheibe 7 abgewandte Endbereich des Steges 10 ein Stück frei über. Bei der in Fig. 2 gezeigten Ausführungsform des Abrollers 1 ist der Steg 10 von dem Aufnahmeelement 9 umhüllt und mit diesem fest verbunden.In the Fig. 2 projections 12 shown are made of plastic and have a certain elasticity, so that even rollers with winding core, which have slightly different diameters, can be absorbed by the receiving element 9 and so supported. How out Fig. 2 it can be seen further that the end region of the web 10 facing away from the disk 7 projects a bit freely. At the in Fig. 2 shown embodiment of the unwinder 1, the web 10 is enveloped by the receiving element 9 and fixedly connected thereto.

Eine weitere Ausführungsform des Abrollers 1 sieht vor, wie Fig. 3 verdeutlicht, dass das Aufnahmeelement 9 mit dem Steg 10 lösbar verbunden ist. Das Aufbringen des Aufnahmeelementes 9 erfolgt derart, dass durch axiale Relativverschiebung, d.h. Verschiebung in Richtung der in Fig. 3 dargestellten Pfeile, das Aufnahmeelement 9 auf die Außenflächen 11 des Steges 10 aufgeschoben wird, so dass die zueinander korrespondierenden Flächenabschnitte 14 und Außenflächen 11 aneinanderliegen. Somit steht auch schon für herkömmliche Abroller ein Nachrüstsatz zur Verfügung, der aus dem Aufnahmeelement 9 besteht.Another embodiment of the unwinder 1 provides, as Fig. 3 illustrates that the receiving element 9 is detachably connected to the web 10. The application of the receiving element 9 takes place such that by axial relative displacement, ie displacement in the direction of Fig. 3 arrows shown, the receiving element 9 is pushed onto the outer surfaces 11 of the web 10, so that the mutually corresponding surface portions 14 and outer surfaces 11 abut each other. Thus, a retrofit kit is already available for conventional dispensers, which consists of the receiving element 9.

Die vorliegende Erfindung beschränkt sich in ihrer Ausführung nicht auf die vorstehend angegebenen bevorzugten Ausführungsbeispiele. Vielmehr ist eine Anzahl von Varianten denkbar, welche von der dargestellten Lösung auch bei grundsätzlich anders gearteten Ausführungen Gebrauch machen. Beispielsweise können die Aufnahmeflächen der Aufnahmeelemente 9 über andere als in den vorstehenden Ausführungsbeispielen gezeigte Geometrien verfügen.The present invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a number of variants are conceivable, which make use of the illustrated solution even with fundamentally different types of execution. For example, the receiving surfaces of the receiving elements 9 may have different geometries than shown in the preceding embodiments.
