Moreover said adapter is in contact with a lateral surface of the winding tube body substantially over its entire periphery on an axial portion of the winding tube body. The invention aims at producing a winding tube of this type which can be reused, easy to use and inexpensive to produce. Therefor, the adapter is designed so that it can be detached from the winding tube body without being damaged.

Description

Wickelhülsemandrel
Die Erfindung betrifft eine Wickelhülse zum Aufnehmen eines bahnförmigen Guts, mit einem zylinderförmig langgestreckten, hohlen Hülsenkörper und mindestens einem ebenfalls zylin- derförmigen, hohlen Adapter, der endseitig verdrehfest an dem Hülsenkörper angebracht ist, dessen Außendurchmesser den des Hülsenkörpers nicht überschreitet und der auf einem axialen Abschnitt des Hülsenkörpers im Wesentlichen auf dem gesamten Umfang mit einer Mantelfläche des Hülsenkörpers in Kontakt steht.The invention relates to a winding tube for receiving a web-like material, with a cylindrical, elongated, hollow tube body and at least one likewise cylindrical, hollow adapter, which is attached at the end to the tube body in a rotationally fixed manner, the outside diameter of which does not exceed that of the tube body and that on an axial one Section of the sleeve body is essentially in contact with an outer surface of the sleeve body over the entire circumference.
Derartige Wickelhülsen werden beispielsweise in der Papierindustrie, insbesondere auch in der Druckindustrie zu Aufnehmen von Papierbahnen eingesetzt. Wickelhülsen bestehen im Wesentlichen aus einem zylinderförmig langgestreckten, hohlen Hülsenkörper aus Papier oder Pappe. In jüngerer Zeit kommen vereinzelt auch aus thermoplastischen Kunststoffen extrudierte Hülsenkörper zum Einsatz.Such winding cores are used, for example, in the paper industry, in particular also in the printing industry, to take up paper webs. Winding tubes essentially consist of a cylindrical, elongated, hollow tube body made of paper or cardboard. More recently, sleeve bodies extruded from thermoplastic materials have also been used occasionally.
Zum Auf- oder Abwickeln des bahnförmigen Gutes wird die Wickelhülse in einer Wickelmaschine auf Spannfutter montiert, die von innen in die Enden des Hülsenkörpers eingreifen und durch Klemmen oder über Formschlusselemente die Einleitung eines Drehmomentes erlauben.To wind or unwind the web-shaped material, the winding tube is mounted in a winding machine on chucks which engage from the inside into the ends of the tube body and which allow the introduction of a torque by clamping or by means of form-locking elements.
Stand der TechnikState of the art
Für Papier- Wickelhülsen ist es bekannt, den Hülsenkörper endseitig mit Adaptern auszustatten, die ein zerstörungsfreies Einspannen der relativ weichen Hülse erlauben. Häufig werden zu diesem Zweck U-förmige Stirnkappen aus Metall auf die offenen Enden des Hülsenkörpers aufgesetzt.For paper winding tubes, it is known to provide the end of the tube body with adapters which allow the relatively soft tube to be clamped in a non-destructive manner. Often, U-shaped metal end caps are placed on the open ends of the sleeve body for this purpose.
Die DE 44 13 810 der Sonoco Products Co. beschreibt einen ringförmigen Adapter, der mit einer kegelstumpfförmigen Außenfläche in eine entsprechend kegelig ausgebildete Innenfläche in den offenen Enden eines Hülsenkörpers aus Papier eingeklebt wird. Der Adapter ver- stärkt zum Einen die Enden der Wickelhülse, die damit den Spannkräften in der Wickelmaschine besser widerstehen, zum Andern erlaubt er die Verwendung eines Hülsenkörpers, dessen Innendurchmesser größer ist als das Spannfutter der Wickelmaschine. Auch bei den relativ preiswert herzustellenden Wickelhülsen aus Papier und Pappe stellt sich heutzutage zunehmend die Aufgabe, zur Vermeidung von Abfall diese Wickelhülsen mehrfach verwendbar zu gestalten. Bei dem in der DE 44 13 810 vorgeschlagenen Adapter werden jedoch einerseits durch die Nerwendung eines Kegelsitzes die Kosten bei der Herstellung so- wohl des Hülsenkörpers als auch des Adapters erhöht. Andererseits verhindert das vorgeschlagene Einkleben des Adapters in den Hülsenkörper die Weiterverwendung eines Adapters aus einem beschädigten Hülsenkörper.DE 44 13 810 from Sonoco Products Co. describes an annular adapter which is glued with a frustoconical outer surface into a correspondingly conical inner surface in the open ends of a sleeve body made of paper. On the one hand, the adapter reinforces the ends of the winding tube, which thus better withstand the tension forces in the winding machine, and on the other hand, it allows the use of a tube body whose inner diameter is larger than the chuck of the winding machine. Even with the relatively inexpensive to manufacture winding sleeves made of paper and cardboard, there is an increasing task today to make these winding sleeves usable to avoid waste. In the adapter proposed in DE 44 13 810, however, on the one hand, the use of a conical seat increases the costs in the production of both the sleeve body and the adapter. On the other hand, the proposed gluing of the adapter into the sleeve body prevents further use of an adapter from a damaged sleeve body.
Kunststoff- Wickelhülsen werden dagegen in der Regel aus Kostengründen aus einfachen Materialien gefertigt, die allerdings regelmäßig den hohen Belastungen durch die Spannfutter nicht gewachsen sind. Die Herstellung von Wickelhülsen unter Nerwendung hochwertiger, verschleißarmer Kunststoffe für die mehrfache Nerwendung ist jedoch aufgrund des hohen Materialaufwandes nicht wirtschaftlich.Plastic winding cores, on the other hand, are generally made of simple materials for cost reasons, but these are usually not able to cope with the high stresses caused by the chuck. However, the production of winding cores using high-quality, low-wear plastics for multiple uses is not economical due to the high cost of materials.
Aufgabetask
Aufgabe der Erfindung ist es, eine Wickelhülse vorzuschlagen, die mehrfach wiederverwend- bar, dabei preiswert herzustellen und variabel in der Anwendung ist.The object of the invention is to propose a winding tube which can be reused several times, is inexpensive to manufacture and is variable in its use.
Lösungsolution
Ausgehend von einer Wickelhülse der eingangs beschriebenen Art wird diese Aufgabe nach der Erfindung dadurch gelöst, dass der Adapter von dem Hülsenkörper zerstörungsfrei demontierbar ist.Starting from a winding tube of the type described in the introduction, this object is achieved according to the invention in that the adapter can be removed from the tube body in a non-destructive manner.
Durch die erfindungsgemäße Demontierbarkeit des Adapters sind die zwei Funktionen der Wickelhülse - die Halterung des bahnförmigen Gutes und die Übertragung eines Drehmomentes aus der Wickelmaschine - auf einfache Weise getrennt. Sowohl für den Hülsenkörper als auch für den Adapter können je nach Anwendungsfall geeignete verschiedene Materialien gewählt werden. Bei Versagen eines Bauteils muss nicht mehr zwangsläufig die gesamte Wi- ckelhülse ersetzt werden. Darüber hinaus wird sogar die Nerwendung von Spannfuttern mit unterschiedlichen Maßen oder unterschiedlichen Formschlusselementen beim Auf- und Abwickeln - also bei Herstellung und Nerwendung - derselben Rolle eines bahnförmigen Gutes möglich. Gerade bei der Nerwendung von Kunststoff kann der Adapter auf besonders einfache Weise formschlüssig mit dem Hülsenkörper verbunden werden - nämlich indem beide in der Kontaktfläche mit ineinander greifenden Nuten und Zähnen ausgestattet werden. Aber auch bei Hülsenkörpern aus Papier können an einem aus Kunststoff gefertigten Adapter angeordnete axiale Zähne sich in das relativ weiche Material des Hülsenkörpers eindrücken und so die formschlüssige Drehmomentübertragung sicherstellen. Als besonders vorteilhaft erweist sich die formschlüssige Verbindung von Adapter und Hülsenkörper auch in Bezug auf die Demontierbarkeit.Because the adapter can be dismantled according to the invention, the two functions of the winding tube - the holding of the web-like material and the transmission of a torque from the winding machine - are separated in a simple manner. Suitable materials can be selected for both the sleeve body and the adapter, depending on the application. If a component fails, it is no longer necessary to replace the entire winding sleeve. In addition, it is even possible to use chucks with different dimensions or different form-locking elements during winding and unwinding - that is to say during manufacture and use - of the same role of a web-like product. Especially when plastic is used, the adapter can be connected to the sleeve body in a form-fitting manner in a particularly simple manner - namely, by providing both in the contact area with interlocking grooves and teeth. But also in the case of paper sleeve bodies, axial teeth arranged on an adapter made of plastic can press into the relatively soft material of the sleeve body and thus ensure the positive torque transmission. The positive connection of adapter and sleeve body also proves to be particularly advantageous with regard to the ability to be dismantled.
Die kraftschlüssige Verbindung von Adapter und Hülsenkörper hingegen ist dann besonders vorteilhaft einzusetzen, wenn der Fertigungsaufwand reduziert werden soll. Dies ist in einfacher Weise dadurch zu erzielen, dass die Kontaktfläche als reine Zylinderfläche ausgebildet wird. Durch Einsetzen eines abgekühlten Adapters in einen bedarfsweise erwärmten Hülsenkörper kann im Bereich der Kontaktfläche mit dem Hülsenkörper eine verdrehfeste Schrumpfpressung erzielt werden.The non-positive connection of adapter and sleeve body, however, is particularly advantageous when the manufacturing effort is to be reduced. This can be achieved in a simple manner by designing the contact surface as a pure cylinder surface. By inserting a cooled adapter in a sleeve body that is heated as required, a torsion-resistant shrinkage compression can be achieved in the area of the contact surface with the sleeve body.
Insbesondere bei geringen Anforderungen an die zu übertragenden Drehmomente kann bereits durch aufgeraute Oberflächen - im Sinne eines Mikro-Formschlusses - die Verdrehfestigkeit sichergestellt werden.In particular with low demands on the torques to be transmitted, the torsion resistance can already be ensured by roughened surfaces - in the sense of a micro-positive fit.
Bei speziellen Anforderungen an die Wickelhülse können die vorgestellten Möglichkeiten zur form- und kraftschlüssigen Verbindung vielfältig untereinander kombiniert und durch die Verwendung aufgerauter Oberflächen verstärkt werden.In the case of special requirements for the winding tube, the options presented for positive and non-positive connection can be combined with one another in a variety of ways and reinforced by the use of roughened surfaces.
Besonders bevorzugt wird die Kontaktfläche von Adapter und Hülsenkörper zylindrisch gestaltet. Durch die Verwendung eines axialen Abschnitts der vorhandenen inneren Mantelfläche des Hülsenkörpers kann wiederum der Herstellaufwand wesentlich gesenkt werden.The contact surface of adapter and sleeve body is particularly preferably cylindrical. By using an axial section of the existing inner lateral surface of the sleeve body, the manufacturing effort can in turn be significantly reduced.
Zusätzlich zur Klemmwirkung in der Kontaktfläche von Adapter und Hülsenkörper ist der Einsatz von Mitteln vorgesehen, die die axiale Verschiebung der Bauteile gegeneinander verhindern. Auf diese Weise können über den Adapter auch axiale Kräfte - beispielsweise zur Positionierung des Wickels in einer Maschine - aufgebracht werden. Besonders bevorzugt ist zu diesem Zweck ein radial vorstehender Bund an dem Adapter vorzusehen. Wird der Außendurchmesser des Bundes an den Außendurchmesser des Hülsenkörpers angeglichen, so kann die äußere Mantelfläche dieses Bundes ebenfalls als Wickelfläche genutzt werden. Beim Transport eines derart gestalteten Wickels trägt das aufgewickelte bahnförmige Gut zusätzlich zur axialen Fixierung des Adapters an dem Hülsenkörper bei. Zur Beeinflus- sung der Abkühleigenschaften des Bundes können in diesen stirnseitige Aussparungen eingebracht werden.In addition to the clamping effect in the contact surface of the adapter and sleeve body, the use of means is provided which prevent the axial displacement of the components against one another. In this way, axial forces can also be applied via the adapter, for example for positioning the winding in a machine. For this purpose it is particularly preferred to provide a radially projecting collar on the adapter. If the outside diameter of the collar is adjusted to the outside diameter of the sleeve body, the outer lateral surface of this collar can also be used as a winding surface. When a winding of this type is transported, the wound web-like material also contributes to the axial fixation of the adapter on the sleeve body. In order to influence the cooling properties of the federal government, cutouts can be made in the front.
Bevorzugt ist weiterhin, auf der inneren Mantelfläche des Adapters Formschlusselemente anzubringen, die die Kombination mit unterschiedlichen Spannfuttern ermöglichen.It is furthermore preferred to fit positive locking elements on the inner surface of the adapter, which enable the combination with different chucks.
Bei Verwendung von zwei erfindungsgemäßen Adaptern ist die Einleitung eines Drehmomen- tes an beiden Enden einer Wickelhülse möglich. Dies bietet sich insbesondere bei sehr langen Wickelhülsen an, wie sie beispielsweise in der Druckindustrie zum Einsatz kommen.When using two adapters according to the invention, the introduction of a torque is possible at both ends of a winding tube. This is particularly useful for very long winding cores, such as those used in the printing industry.
Bevorzugt wird der Adapter aus einem widerstandsfähigeren Material gefertigt als der Hülsenkörper. Die Verwendung hochwertiger - und damit teurer - Rohstoffe, zum Beispiel hochverschleißfester Kunststoffe wie faserverstärktes Polyamid kann so auf relativ kleine Bauteile beschränkt werden.The adapter is preferably made of a more resistant material than the sleeve body. The use of high-quality - and therefore more expensive - raw materials, for example highly wear-resistant plastics such as fiber-reinforced polyamide, can thus be restricted to relatively small components.
Der Adapter kann günstig im Spritzgussverfahren gefertigt werden. Insbesondere ist so die Ausformung von mehreren komplexen Merkmalen wie Nuten und Zähnen in der Kontaktfläche, von einem Bund mit stirnseitigen Aussparungen und von Formschlusselementen auf der inneren Mantelfläche in einem Arbeitsgang möglich.The adapter can be manufactured cheaply using the injection molding process. In particular, the formation of several complex features such as grooves and teeth in the contact surface, of a collar with recesses on the end and of form-locking elements on the inner lateral surface is possible in one operation.
Bei einer möglichen Ausführungsform des Hülsenkörpers wird dieser aus Papier oder Pappe gefertigt, da so einerseits die Produktionskosten gering gehalten, andererseits Recyclingmaterialien einer sinnvollen Verwendung zugeführt werden können.In a possible embodiment of the sleeve body, it is made of paper or cardboard, since on the one hand this keeps the production costs low, and on the other hand recycling materials can be used in a sensible manner.
Die Verwendung höherwertiger Hülsenkörper aus thermoplastisch formbaren Kunststoffen, beispielsweise aus Styrolbutadien bietet sich an, wenn die Kontaktfläche von Adapter und Hülsenkörper Nuten und Zähne aufweisen soll. Bei Herstellung dieser Hülsenkörper durch Extrusion können diese Formschlusselementen unmittelbar angeformt werden und verlaufen über die ganze Länge des Hülsenkörpers.The use of high-quality sleeve bodies made of thermoplastically moldable plastics, for example of styrene butadiene, is appropriate if the contact surface of the adapter and sleeve body is to have grooves and teeth. When these sleeve bodies are produced by extrusion, these positive locking elements can be molded on directly and run over the entire length of the sleeve body.
Bei Herstellung des Hülsenkörpers durch Extrusion kann dieser darüber hinaus in beliebigen Längen je nach dem konkreten Bedarf hergestellt werden. AusführungsbeispielWhen the sleeve body is produced by extrusion, it can also be produced in any length depending on the specific need. embodiment
