Description

Die Erfindung betrifft eine Bandaufwickelvorrichtung gemäß den Merkmalen des Oberbegriffs des Anspruchs 1 und ein Verfahren zum Fixieren eines Abschnitts eines durch Wärmeeintrag zumindest an einer Oberfläche schmelzbaren Bands auf einem bereits um eine Spule gewickelten Teil des Bands gemäß dem Oberbergriff des Anspruchs 7.The invention relates to a tape winding device according to the features of the preamble of claim 1 and a method for fixing a section of a tape that can be melted by heat input at least on one surface on a part of the tape already wound around a reel according to the preamble of claim 7.

Bei der Herstellung von Bändern, Fäden und Fasern aus Kunststoff werden diese im Allgemeinen zur sicheren platzsparenden Lagerung und späteren Weiterverarbeitung mittels einer Aufwickelvorrichtung auf Spulen aufgewickelt. Eine Bandaufwickelvorrichtung zum Aufwickeln eines Bands auf eine Spule ist beispielsweise aus dem Dokument WO 2004/101415 A1 bekannt. Zum Aufwickeln des Bands auf der Spule wird das Band zur Spule zugeführt und durch Drehung der Spule mittels eines Spulenantriebs lagenweise um die Spule gewickelt. Ferner umfasst die Bandaufwickelvorrichtung eine Changiereinrichtung, mittels welcher das Band gleichmäßig auf die Spule aufgewickelt werden kann
Die EP 3 281 902 A1 offenbart eine Bandaufwickelvorrichtung, wobei ein Ende des Bands reibschlüssig und/oder formschlüssig an der gewickelten Spule gesichert wird.In the production of ribbons, threads and fibers from plastic, these are generally wound onto spools by means of a winding device for safe space-saving storage and subsequent further processing. A tape winding device for winding a tape onto a reel is for example from the document WO 2004/101415 A1 known. To wind the tape on the reel, the tape is fed to the reel and wound in layers around the reel by rotating the reel by means of a reel drive. Furthermore, the tape winding device comprises a traversing device, by means of which the tape can be wound evenly onto the reel
The EP 3 281 902 A1 discloses a tape winder wherein one end of the tape is frictionally and / or positively secured to the wound reel.

Die EP 1 627 840 A1 offenbart ein Garnwickel, dessen Faden einen aus dem Wickelinneren herausstehenden Anfangsabschnitt und einen an der äußeren Mantelfläche des Garnwickels sich erstreckenden Endabschnitt aufweist, wobei der Endabschnitt des aus einem unter Hitzeeinwirkung verschleißbaren Material bestehenden Fadens mit den an der äußeren Mantelfläche des Garnwickels liegenden Fadenabschnitten verschweißt ist.The EP 1 627 840 A1 discloses a yarn package, the thread of which has a starting section protruding from the inside of the package and an end section extending on the outer jacket surface of the yarn package, the end section of the thread consisting of a material which can be worn under the action of heat is welded to the thread sections lying on the outer jacket surface of the yarn package.

Die DE 21 39 930 A1 offenbart eine Spule und einen auf dieser Spule aufgewickelten Faden, wobei der Faden mindestens einen Teil aufweist, der mit der Spule heißverschweißt ist.The DE 21 39 930 A1 discloses a bobbin and a thread wound on that bobbin, the thread having at least a portion which is heat-sealed to the bobbin.

Wenn eine Spule voll ist, wird sie gegen eine leere Spule ausgetauscht, wobei dazu einerseits manuell das Band durchtrennt werden muss und andererseits ein durch das Durchtrennen entstehendes Bandende von Hand mittels eines Stücks Klebeband an der vollen Spule fixiert werden muss. Diese Fixierung des Bandendes ist notwendig, damit sich das Band bei einer anschließenden Handhabung oder beim Transport der Spule nicht selbsttätig von der Spule abwickelt und ein Verfangen des Bandendes an anderen Elementen vermieden wird. Das Fixieren des Bandendes per Hand ist aber nicht nur zeitaufwendig, es stellt auch aufgrund der Vielzahl an Spulen, die in industriellen Produktionsanlagen gewickelt werden, eine sehr mühsame monotone Arbeit dar.When a reel is full, it is exchanged for an empty reel, whereby on the one hand the tape has to be cut manually and on the other hand a tape end resulting from the cutting has to be fixed to the full reel using a piece of adhesive tape. This fixing of the end of the tape is necessary so that the tape does not unwind automatically from the reel during subsequent handling or transport of the reel and the end of the tape is prevented from getting caught on other elements. Fixing the end of the tape by hand is not only time-consuming, it is also a very tedious, monotonous job due to the large number of spools that are wound in industrial production systems.

Es ist die Aufgabe der vorliegenden Erfindung eine Bandaufwickelvorrichtung bereit zu stellen, die die oben beschriebenen Nachteile des Standes der Technik überwindet.It is the object of the present invention to provide a tape winding device which overcomes the disadvantages of the prior art described above.

Erfindungsgemäß wird die Aufgabe durch Fortbildung einer eingangs erwähnten Bandaufwickelvorrichtung gemäß den kennzeichnenden Merkmalen des Anspruchs 1 und durch Fortbildung eines eingangs erwähnten Bandaufwickelverfahrens gemäß den kennzeichnenden Merkmalen des Anspruchs 7 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche und der Beschreibung.According to the invention, the object is achieved by developing a tape winding device mentioned at the beginning according to the characterizing features of claim 1 and by developing a tape winding method mentioned at the beginning according to the characterizing features of claim 7. Preferred embodiments of the invention are the subject matter of the dependent claims and the description.

Die erfindungsgemäße Bandaufwickelvorrichtung umfasst eine Bandbefestigungsvorrichtung, welche dazu ausgebildet ist, thermische Energie in einen Erwärmungsabschnitt des Bands einzubringen. Dieser Erwärmungsabschnitt des Bands liegt in einem Teil des der Spule zugeführten Bands, der noch nicht um die Spule gewickelt ist, oder gerade auf die Spule aufgewickelt wird, oder bereits zu einem Teil, z.B. über einen Winkel von 30 Grad, auf die Spule aufgewickelt ist. Es sei hier noch darauf hingewiesen, dass der Begriff "Band", wie hierin verwendet, auch Fasern, Filamente oder Fäden umfasst.The tape winding device according to the invention comprises a tape fastening device which is designed to introduce thermal energy into a heating section of the tape. This heating section of the tape lies in a part of the tape fed to the reel that has not yet been wound around the reel, or is currently being wound onto the reel, or is already partly wound onto the reel, for example over an angle of 30 degrees . It should also be pointed out here that the term “tape”, as used herein, also includes fibers, filaments or threads.

Durch die von der Bandbefestigungsvorrichtung in das Band eingebrachte thermische Energie wird das Band in dem oben genannten Erwärmungsabschnitt zumindest teilweise oberflächlich soweit aufgeheizt, dass das Band auf seiner Oberfläche aufschmilzt und an einem bereits zumindest einmal um die Spule gewickelten Teil des Bands festklebt. Bevorzugt wird der Erwärmungsabschnitt des Bands, in den die thermische Energie eingebracht wird, so festgelegt, dass die Spule möglichst vollgefüllt wird, bevor das Band in besagtem Erwärmungsabschnitt mit thermischer Energie beaufschlagt und an dem bereits um die Spule gewickelten Teil des Bands fixiert wird. Hierdurch ist der Vorteil erhalten, dass der Erwärmungsabschnitt des Bands ohne weitere Klebemittel und ohne Handarbeit an dem bereits um die Spule gewickelten Teil des Bands befestigt werden kann und die Spule somit für die weitere Verwendung leichter handhabbar ist. Da das Band in dem Erwärmungsabschnitt vorzugsweise nur oberflächlich aufgeschmolzen wird, kann das Band in dem besagten Erwärmungsabschnitt bei Bedarf wieder leicht von dem bereits um die Spule gewickelten Teil des Bands gelöst werden.Due to the thermal energy introduced into the tape by the tape fastening device, the tape is at least partially superficially heated in the above-mentioned heating section to such an extent that the tape melts on its surface and sticks to a part of the tape that has already been wound around the reel at least once. The heating section of the strip into which the thermal energy is introduced is preferably set so that the coil is filled as completely as possible before the strip is subjected to thermal energy in said heating section and is fixed to the part of the strip already wound around the coil. This has the advantage that the heating section of the tape can be attached to the part of the tape that has already been wound around the reel without further adhesive and without manual work, and the reel is therefore easier to handle for further use. Since the tape is preferably only melted on the surface in the heating section, the tape in the heating section can be easily detached from the part of the tape that has already been wound around the reel if necessary.

Die Bandbefestigungsvorrichtung ist durch Elektroden zur Erzeugung von zumindest elektrischen Funken gebildet.The tape fastening device is formed by electrodes for generating at least electrical sparks.

Vorteilhaft erfolgt die Einbringung von thermischer Energie in das Band mittels der Bandbefestigungsvorrichtung, wenn diese nicht erfindungsgemäß von einem Heizelement gebildet ist, in einem Abstand von der Spule. Die Spule wird während oder nach dem Einbringen von thermischer Energie in das Band durch den Spulenantrieb weitergedreht, wodurch der wärmebeaufschlagte und dadurch aufgeschmolzene Erwärmungsabschnitt des Bands mit dem bereits auf der Spule aufgewickelten Teil des Bands in Kontakt kommt und daran festklebt. Dreht sich die Spule während der Zufuhr von thermischer Energie weiter, so kann je nachdem, wie lange die thermische Energie auf das Band eingebracht wird, die Länge des aufgeschmolzenen Erwärmungsabschnitts verändert werden. Hierdurch ist der Vorteil erhalten, dass das Bandende über eine einstellbare Länge mit der obersten auf der Spule befindlichen Bandlage verbunden werden kann, wodurch die Festigkeit der Verbindung variiert werden kann. Bevorzugt wird aber der besagte Erwärmungsabschnitt des Bandendes, in den die thermische Energie eingebracht wird, sehr kurz gewählt, um das Bandende wieder leicht lösen zu können.Thermal energy is advantageously introduced into the tape by means of the tape fastening device, if this is not formed according to the invention by a heating element, at a distance from the coil. The reel is rotated further by the reel drive during or after the introduction of thermal energy into the band, whereby the heated and thereby fused heating section of the band comes into contact with the part of the band already wound on the reel and sticks to it. If the coil continues to rotate during the supply of thermal energy, the length of the melted heating section can be changed depending on how long the thermal energy is applied to the strip. This has the advantage that the tape end over an adjustable length with the top one on the reel located tape layer can be connected, whereby the strength of the connection can be varied. Preferably, however, the said heating section of the strip end into which the thermal energy is introduced is selected to be very short in order to be able to easily detach the strip end again.

Bei einer Elektroden umfassenden Bandbefestigungsvorrichtung befindet sich vorteilhaft der Erwärmungsabschnitt des Bands während des Einbringens von thermischer Energie durch die Bandbefestigungsvorrichtung in einem Arbeitsbereich, in dem das zur Spule zugeführte Band gerade auf die Spule aufgewickelt wird bzw. bis zu einem gewissen Umschlingungsbereich, z.B. von 30 Grad bezogen auf das Bandende, bereits auf die Spule aufgewickelt ist. Mittels der Elektroden kann die thermische Energie dosiert punktgenau in den Arbeitsbereich eingebracht werden, wodurch eine punktgenaue Schweißung ohne Beschädigung des Bands sichergestellt werden kann. Das hat den Vorteil, dass reproduzierbar Spulen mit hoher Qualität ohne Bandschädigungen und mit exakt der gleichen Menge an Band erzeugt werden können.In a tape fastening device comprising electrodes, the heating section of the tape is advantageously located during the introduction of thermal energy by the tape fastening device in a working area in which the tape fed to the reel is being wound onto the reel or up to a certain wrapping area, e.g. 30 degrees based on the end of the tape, is already wound onto the spool. By means of the electrodes, the thermal energy can be introduced into the work area in a precisely dosed manner, which ensures a precise weld without damaging the strip. This has the advantage that reels of high quality can be produced reproducibly without damage to the tape and with exactly the same amount of tape.

Es sei hier noch darauf hingewiesen, dass auch bei einer ein Heizelement umfassenden Bandbefestigungsvorrichtung Spulen von hoher Qualität erzeugt werden können, wobei die Einbringung der thermischen Energie nicht so exakt steuerbar ist wie bei einer eine Elektrode umfassenden Bandbefestigungseinrichtung.It should be pointed out here that coils of high quality can also be produced with a tape fastening device comprising a heating element, the introduction of the thermal energy not being as precisely controllable as with a tape fastening device comprising an electrode.

Bei einer durch die Elektroden gebildeten Bandbefestigungsvorrichtung weist die Bandaufwickelvorrichtung vorteilhaft eine Bandschneidevorrichtung auf, mit der das zur Spule zugeführte Band durchtrennt werden kann.In the case of a tape fastening device formed by the electrodes, the tape winding device advantageously has a tape cutting device with which the tape fed to the reel can be cut.

In einer sehr einfachen Ausführungsvariante ist die Spule 3 im Wesentlichen nur durch einen zylindrischen Spulenkern gebildet, auf den eine Vielzahl von Bandlagen gewickelt werden. Figure 1 shows a first embodiment of a tape winding device 1 not according to the invention in a simplified perspective view.

In a very simple embodiment variant, the coil 3 is essentially only formed by a cylindrical coil core on which a large number of tape layers are wound.

Der Spulenantrieb 4 ist durch einen elektrischen oder pneumatischen Motor gebildet, wobei der Spulenantrieb 4 und die Spule 3 direkt oder über ein zwischengeschaltetes Getriebe gekoppelt sind.The tape winding device 1 has a motorized reel drive 4 which rotates the reel 3 in order to wind the tape 2 onto the reel 3. The coil drive 4 is formed by an electric or pneumatic motor, the coil drive 4 and the coil 3 being coupled directly or via an interposed gear.

Weiterhin weist die Bandaufwickelvorrichtung 1 eine durch ein Heizelement 5 gebildete Bandbefestigungsvorrichtung auf. Das Heizelement 5 ist dazu ausgebildet, thermische Energie in das Band 2 einzubringen, indem das Heizelement 5 mit dem zur Spule 3 zugeführten Band 2 in Kontakt oder außer Kontakt gebracht wird. Das Heizelement 5 ist bevorzugt ein elektrisches Heizelement, z.B. eine elektrisch beheizte Heizpatrone. Es besteht aber auch die Möglichkeit, die Heizpatrone mittels einer Flamme zu erhitzen. Das Heizelement 5 kann auch als elektrisch oder mittels einer Flamme beheizbarer Draht ausgebildet sein.Furthermore, the tape winding device 1 has a tape fastening device formed by a heating element 5. The heating element 5 is designed to introduce thermal energy into the strip 2 by bringing the heating element 5 into contact with or out of contact with the strip 2 fed to the coil 3. The heating element 5 is preferably an electrical heating element, for example an electrically heated heating cartridge. But there is also the possibility of heating the heating cartridge with a flame. The heating element 5 can also be designed as a wire that can be heated electrically or by means of a flame.

Das Heizelement 5 ist in einem Arbeitsbereich 9 positioniert, der in dieser Ausführungsform von der Spule 3 beabstandet ist. Je nach verwendetem Material und Durchmesser des Bands 2 wird der Abstand des Arbeitsbereichs 9 von der Spule 3 gewählt, wobei der Arbeitsbereich 9 aber bevorzugt möglichst nahe an der Spule 3 liegen sollte.The heating element 5 is positioned in a working area 9, which in this embodiment is spaced from the coil 3. Depending on the material used and the diameter of the tape 2, the distance between the working area 9 and the reel 3 is selected, but the working area 9 should preferably be as close as possible to the reel 3.

Das Heizelement 5 ist zweckmäßig so in Bezug auf die Spule 3 positioniert, dass das Band 2 im Arbeitsbereich 9 automatisch bei voller Spule 3 durch den sich in Abhängigkeit vom Füllzustand der Spule 3 verändernden Spulendurchmesser mit dem Heizelement 5 in Kontakt kommt und somit thermische Energie in einen Erwärmungsabschnitt 11 des Bands 2 einbringt. Das hat den Vorteil, dass die Bandaufwickelvorrichtung 1 sehr einfach und kostengünstig aufgebaut werden kann und in wiederkehrender Weise Spulen 3 mit gleichem Füllzustand erzeugt werden können.The heating element 5 is expediently positioned in relation to the reel 3 that the tape 2 in the working area 9 automatically comes into contact with the heating element 5 when the reel 3 is full due to the reel diameter that changes depending on the filling level of the reel 3, and thus thermal energy in a heating section 11 of the belt 2 introduces. This has the advantage that the tape winding device 1 can be constructed very simply and inexpensively and reels 3 with the same filling state can be produced in a recurring manner.

Es besteht aber auch die Möglichkeit, dass das Heizelement 5 manuell oder durch einen Stellantrieb angetrieben mit dem Band 2 im Arbeitsbereich 9 in Kontakt gebracht bzw. außer Kontakt gebracht wird, um in einem definierten Zeitraum thermische Energie in den Erwärmungsabschnitt 11 des Bands 2 einzubringen. Der Stellantrieb kann beispielsweise durch einen elektrischen, pneumatischen oder hydraulischen Linearantrieb oder einen Rotationsantrieb gebildet sein. Vorteilhaft wird der Stellantrieb und/oder das Heizelement 5 durch einen Steuercomputer, wie einen Mikrocontroller oder eine SPS, gesteuert.However, there is also the possibility that the heating element 5 is brought into contact or out of contact with the belt 2 in the working area 9 manually or driven by an actuator in order to introduce thermal energy into the heating section 11 of the belt 2 within a defined period of time. The actuator can for example be formed by an electric, pneumatic or hydraulic linear drive or a rotary drive. The actuator and / or the heating element 5 is advantageously controlled by a control computer, such as a microcontroller or a PLC.

Die Spule 3 wird durch den Spulenantrieb 4 weiter angetrieben, während das Heizelement 5 mit dem Band 2 im Arbeitsbereich 9 in Kontakt steht. Hierdurch ist der Vorteil erhalten, dass unabhängig von einer Bewegung des Heizelements 5 der Erwärmungsabschnitt 11 beliebig lange gewählt werden kann. Je länger der oberflächlich aufgeschmolzene Erwärmungsabschnitt 11 ist, desto größer ist eine Haftlänge, mit der die nebeneinander liegenden Bänder 2 aneinanderhaften.The reel 3 is driven further by the reel drive 4, while the heating element 5 is in contact with the belt 2 in the working area 9. This has the advantage that the heating section 11 can be selected as long as desired regardless of a movement of the heating element 5. The longer the superficially melted heating section 11, the greater is an adhesive length with which the strips 2 lying next to one another adhere to one another.

In einer weiteren Ausführungsform ist aber vorgesehen, dass die Spule 3 stillsteht oder in Relation zu einer Bewegung des Heizelements 5 nur sehr langsam angetrieben wird, solange das Heizelement 5 mit dem Band 2 im Arbeitsbereich 9 in Kontakt steht. Dabei fällt der Erwärmungsabschnitt 11 sehr kurz aus. Bei stillstehender Spule 3 wird diese nach dem Aufschmelzen des Erwärmungsabschnitts 11 durch das Heizelement 5 wieder gedreht, um das Band 2 weiter auf die Spule 3 aufzuwickeln, wodurch der Erwärmungsabschnitt 11 mit bereits auf die Spule 3 aufgewickelten Teilen 10 des Bands 2 in Kontakt kommt und daran anhaftet.In a further embodiment, however, it is provided that the coil 3 stands still or is only driven very slowly in relation to a movement of the heating element 5, as long as the heating element 5 is in contact with the belt 2 in the work area 9. The heating section 11 is very short. When the reel 3 is stationary, it is rotated again by the heating element 5 after the heating section 11 has melted in order to continue to wind the tape 2 onto the reel 3, whereby the heating portion 11 comes into contact with parts 10 of the tape 2 already wound on the reel 3 and attached to it.

In einer besonders bevorzugten Ausführungsvariante durchtrennt das Heizelement 5 das Band 2 im Erwärmungsabschnitt 11. Ein dabei entstehendes Ende des Bands 2 wird durch Weiterdrehen der Spule 3 oder auch durch Schwerkraft an dem zumindest einmal um die Spule 3 gewickelten Teil 10 des Bands 2 fixiert. Hierdurch ist der Vorteil erhalten, dass auf eine zusätzliche Bandschneidevorrichtung, wie zum Beispiel ein manuell oder automatisch betätigtes Messer, verzichtet werden kann.In a particularly preferred embodiment, the heating element 5 cuts through the band 2 in the heating section 11. An end of the band 2 that is created in this way is fixed to the part 10 of the band 2 that is wound at least once around the reel 3 by further turning the coil 3 or by gravity. This has the advantage that an additional tape cutting device, such as a manually or automatically operated knife, can be dispensed with.

In einer weiteren Ausführungsvariante ist vorgesehen, dass bei angetriebener Spule 3 in einem ersten Schritt das Heizelement 5 nur leicht an das Band 2 im Arbeitsbereich 9 angedrückt wird, um einen Erwärmungsabschnitt 11 des Bands oberflächlich über eine bestimmte Länge aufzuschmelzen, und anschließend das Heizelement 5 fester gegen das Band 2 gedrückt wird, um das Band 2 mittels Schmelzen zu durchtrennen. Je nach Leistung des Heizelements 5 kann es auch ausreichend sein, das Heizelement 5 zum Aufschmelzen des Bandes 2 im Arbeitsbereich 9 nur in die Nähe des Bands 2 zu bringen und das Heizelement 5 nur zum Durchtrennen des Bands 2 direkt mit dem Band 2 in Kontakt zu bringen.In a further embodiment it is provided that with the coil 3 driven, in a first step the heating element 5 is only lightly pressed against the belt 2 in the working area 9 in order to melt a heating section 11 of the belt over a certain length, and then the heating element 5 more firmly is pressed against the band 2 to cut the band 2 by means of melting. Depending on the power of the heating element 5, it may also be sufficient to melt the heating element 5 of the band 2 in the working area 9 only in the vicinity of the band 2 and to bring the heating element 5 directly into contact with the band 2 only to cut the band 2.

Figur 2 zeigt eine zweite Ausführungsform der erfindungsgemäßen Bandaufwickelvorrichtung 6 in einer vereinfachten perspektivischen Darstellung. Elemente, die den Elementen der Bandaufwickelvorrichtung 1 gemäß Figur 1 gleichen, sind mit gleichen Bezugszeichen versehen; zu ihrer Erläuterung wird auf die obige Beschreibung verwiesen. Figure 2 shows a second embodiment of the tape winding device 6 according to the invention in a simplified perspective illustration. Elements that correspond to the elements of the tape winding device 1 according to Figure 1 the same are provided with the same reference numerals; for their explanation, reference is made to the above description.

Im Unterschied zu der in Figur 1 dargestellten Bandaufwickelvorrichtung 1 umfasst die Bandaufwickelvorrichtung 6 eine durch Elektroden 7 gebildete Bandbefestigungsvorrichtung. Die Elektroden 7 sind voneinander beabstandet angeordnet, wobei zwischen den Elektroden 7 ein Isolator 14 angeordnet ist, der aus einem nicht leitfähigen Material besteht. Die Elektroden 7 sind ausgebildet, elektrische Funken 8 zu erzeugen. Der Isolator 14 verhindert, dass ein erzeugter elektrischer Funken 8 den kürzesten Weg zwischen den Elektroden 7 nimmt. Durch den Isolator 14 wird der Funken 8 gezwungen, den zweitbesten Weg um den Isolator 14 herum zu nehmen. Dadurch bedingt kann die durch den Funken 8 entstehende thermische Energie in einem Arbeitsbereich 9 direkt in das Band 2 eingetragen werden, wobei der Isolator 14 im Arbeitsbereich 9 sehr nahe an das Band 2 herangeführt werden muss, wodurch der Funken 8 durch das Band 2 durchschlägt und die thermische Energie präzise in das Band 2 eingetragen wird. Das Band 2 wird in einem Erwärmungsabschnitt 11, der in diesem Fall nur die Größe eine Schweißpunkts aufweist, an einem um die Spule 3 gewickelten Teil 10 des Bands 2 fixiert. Siehe dazu insbesondere auch Figur 3. Durch den Eintrag der thermischen Energie mittels des Funkens 8 ist der Vorteil erhalten, dass die thermische Energie sehr dosiert, effizient und genau in das Band 2 eingebracht werden kann, ohne dass das Band 2 beschädigt wird.In contrast to the in Figure 1 The tape winding device 1 shown in the figure, the tape winding device 6 comprises a tape fastening device formed by electrodes 7. The electrodes 7 are arranged at a distance from one another, with an insulator 14 made of a non-conductive material being arranged between the electrodes 7. The electrodes 7 are designed to generate electrical sparks 8. The insulator 14 prevents a generated electrical spark 8 from taking the shortest path between the electrodes 7. The spark 8 is forced by the insulator 14 to take the second best path around the insulator 14. As a result, the thermal energy generated by the spark 8 can be entered directly into the belt 2 in a work area 9, the insulator 14 in the work area 9 having to be brought very close to the belt 2, whereby the spark 8 breaks through the belt 2 and the thermal energy is entered precisely into the band 2. The band 2 is fixed in a heating section 11, which in this case only has the size of a weld point, on a part 10 of the band 2 wound around the reel 3. See also in particular Figure 3 . By introducing the thermal energy by means of the spark 8, the advantage is obtained that the thermal energy can be introduced into the strip 2 in a very metered, efficient and precise manner without the strip 2 being damaged.

Die Elektroden 7 sind vorteilhaft so gegenüber der Spule 3 befestigt, dass das Band 2 im Arbeitsbereich 9 bei voller Spule 3 automatisch durch den sich in Abhängigkeit eines Füllzustandes der Spule 3 verändernden Spulendurchmesser in Reichweite der Elektroden 7 kommt, um mittels dem Funken 8 thermische Energie in den Erwärmungsabschnitt 11 des Bands 2 einzutragen und mittels dem dabei entstehenden Schweißpunkt den Erwärmungsabschnitt 11 des Bands an dem bereits auf die Spule 3 aufgewickelte Teil 10 des Bands 2 zu befestigen. Das hat den Vorteil, dass auf einen Stellantrieb zur Bewegung der Elektroden 8 verzichtet werden kann.The electrodes 7 are advantageously attached to the coil 3 in such a way that the strip 2 in the working area 9 when the bobbin 3 is full is automatically within reach of the electrodes 7 due to the coil diameter that changes depending on the filling state of the coil 3, in order to generate thermal energy by means of the spark 8 to be entered in the heating section 11 of the strip 2 and, by means of the weld point that is created, to attach the heating section 11 of the strip to the part 10 of the strip 2 already wound onto the reel 3. This has the advantage that an actuator for moving the electrodes 8 can be dispensed with.

Weiterhin besteht die Möglichkeit, dass die Elektroden 7 manuell oder von einem Stellantrieb angetrieben so gegenüber dem Erwärmungsabschnitt 11 positioniert werden, dass mittels des Funkens 8 ausreichend thermische Energie aufgebracht werden kann, um den Erwärmungsabschnitt 11 des Bands 2 mittels eines Schweißpunktes auf dem bereits auf der Spule 3 aufgewickelten Teil 10 des Bands 2 zu befestigen. Der Stellantrieb kann beispielsweise durch einen elektrischen, pneumatischen oder hydraulischen Linearantrieb oder einen Rotationsantrieb gebildet sein.Furthermore, there is the possibility that the electrodes 7 are positioned manually or driven by an actuator opposite the heating section 11 so that sufficient thermal energy can be applied by means of the spark 8 to heat the heating section 11 of the strip 2 by means of a welding point on the already on the Coil 3 to fasten the wound part 10 of the tape 2. The actuator can for example be formed by an electric, pneumatic or hydraulic linear drive or a rotary drive.

Vorteilhaft wird der Erwärmungsabschnitt 11 des Bands 2, in den die thermische Energie durch den elektrischen Funken 8 eingebracht wird, in Abhängigkeit von zumindest einem der folgenden Parameter gewählt:

  • einer Menge an Band 2, das auf die Spule 3 aufgewickelt werden soll (Wunschlauflänge);
  • einem Wunschdurchmesser der vollen Spule 3;
  • einer Geschwindigkeit, mit der die Spule 3 beim Aufwickeln des Bands 2 angetrieben wird;
  • einer Banddicke;
  • einem Bandmaterial, insbesondere einer Art und Anzahl an Additiven im Bandmaterial; und/oder
  • einer Bandbreite.
The heating section 11 of the strip 2, into which the thermal energy is introduced by the electrical spark 8, is advantageously selected as a function of at least one of the following parameters:
  • an amount of tape 2 to be wound on reel 3 (desired run length);
  • a desired diameter of the full bobbin 3;
  • a speed at which the spool 3 is driven when the tape 2 is wound up;
  • a tape thickness;
  • a strip material, in particular a type and number of additives in the strip material; and or
  • a bandwidth.

Bevorzugt weist die Bandaufwickelvorrichtung einen Steuercomputer, insbesondere eine SPS oder einen Mikrocontroller, auf, der mit den Elektroden 7 verbunden ist und eine Bildung der elektrischen Funken 8 und eine Einbringung der dabei entstehenden thermischen Energie in das Band 2 steuert. Vorteilhaft wählt der Steuercomputer in Abhängigkeit zumindest eines der obigen Parameter den Erwärmungsabschnitt 11, in den der Funken 8 eingebracht wird, aus. Der Erwärmungsabschnitt 11 wird vorteilhaft durch einfaches festlegen eines Zeitpunkts, wann der Funken in das Band 2 eingebracht wird, festgelegt.The tape winding device preferably has a control computer, in particular a PLC or a microcontroller, which is connected to the electrodes 7 and controls the formation of the electrical sparks 8 and the introduction of the resulting thermal energy into the tape 2. The control computer advantageously selects the heating section 11 into which the spark 8 is introduced as a function of at least one of the above parameters. The heating section 11 is advantageously defined by simply defining a point in time when the spark is introduced into the strip 2.

Vorteilhaft weist die Bandaufwickelvorrichtung 6 eine Bandschneidevorrichtung 15 auf, die dazu ausgebildet ist, das Band 2 nach dem oder vor dem Befestigen des Erwärmungsabschnitts 11 des Bands 2 an dem bereits um die Spule 3 gewickelten Teil 10 des Bands 2 zu durchtrennen. Vorteilhaft wird das Band 2 beabstandet vom Erwärmungsabschnitt 11 durchtrennt. Dabei wird zwischen dem Erwärmungsabschnitt 11 und einem beim Durchtrennen entstehenden Ende 12 des Bands 2 ein Überstand 13 gebildet. Hierdurch ist der Vorteil erhalten, dass das Ende 12 sofort ersichtlich ist und dass das Band 2 leicht am Überstand 13 ergriffen werden kann. Vorteilhaft wird der Überstand 13 so gewählt, dass dieser leicht ergriffen werden kann, aber dennoch keine Gefahr besteht, dass sich der Überstand 13 bei der Handhabung oder beim Transport der Spule 3 an anderen Elementen verfängt. Durch den Überstand 13 kann die Haftung des Erwärmungsabschnitts 11 des Bands 2 an dem bereits um die Spule 3 gewickelten Teil 10 des Bands 2 einfach gelöst werden. Der Überstand ist vorteilhaft ca. 3cm lang.The tape winding device 6 advantageously has a tape cutting device 15 which is designed to cut the tape 2 after or before the fastening of the heating section 11 of the tape 2 to the part 10 of the tape 2 already wound around the reel 3. The band 2 is advantageously severed at a distance from the heating section 11. In this case, a protrusion 13 is formed between the heating section 11 and an end 12 of the strip 2 that is produced during severing. This has the advantage that the end 12 is immediately visible and that the tape 2 can easily be gripped at the protrusion 13. The protrusion 13 is advantageous selected so that this can be easily grasped, but there is still no risk of the protrusion 13 getting caught on other elements during handling or during transport of the coil 3. Due to the protrusion 13, the adhesion of the heating section 11 of the band 2 to the part 10 of the band 2 already wound around the reel 3 can be easily released. The protrusion is advantageously about 3cm long.

Vorteilhaft steht die Spule 3 während der Einbringung von thermischer Energie mittels des Funkens 8 in das Band 2 im Erwärmungsabschnitt 11 still. Es besteht aber auch die Möglichkeit, dass sich die Spule 3 zumindest langsam dreht.The coil 3 advantageously stands still during the introduction of thermal energy by means of the spark 8 into the strip 2 in the heating section 11. But there is also the possibility that the coil 3 rotates at least slowly.

Figur 3 zeigt die zweite Ausführungsvariante der erfindungsgemäßen Bandaufwickelvorrichtung 6 gemäß Figur 2 in einer Seitensicht während der Einbringung von thermischer Energie mittels eines Funkens 8 in dem Arbeitsbereich 9 in das Band 2. Figure 3 shows the second variant embodiment of the tape winding device 6 according to the invention according to FIG Figure 2 in a side view during the introduction of thermal energy by means of a spark 8 in the work area 9 into the belt 2.
