Abstract

In an apparatus for winding up flat material webs or foils, by means of a rotary winding cylinder, the cylinder is provided with a longitudinal slot and which accommodates a clamping device and by which a portion of the web to be wound up and introduced through the slot by means of a vertically movable blade which causes the web to be seized and firmly held. Upon finishing a roll, the seized portion of the web is disengaged and the roll can be withdrawn by means of a take-off device. This makes it possible to wind up the web at a high speed without forming folds. Also, the laps of the formed roll are very firmly wound and their edges are throughout in a definite position so that they may be heated in a working station.

Description

Die Erfindung bezieht sich auf eine Einrichtung zum Wickeln von flächigen Stoff- oder Folienbahnen mittels einer rotierend anbreibbaren Wickelwalze, in die zur Verspannung der aufzuwickelnden Bahn eine Klemmvorrichtung eingesetzt ist, in die die Bahn durch eine in die Wickelwalze eingearbeitete Längsnut teilweise einführbar und nach Erstellung des Wickels von der Klemmvorrichtung lösbar ist.The invention relates to a device for winding flat fabric or film webs by means of a rotatably drivable winding roller, in which a clamping device is used for tensioning the web to be wound, into which the web can be partially inserted through a longitudinal groove incorporated into the winding roller and after the creation of the Winding is detachable from the clamping device.

Wickelwalzen zur Aufnahme von Stoffbahnen, um diese zu komprimieren und somit leicht transportieren zu können, sind in Form von Wickelrohren aus Metall oder Hartpapier bekannt. Hierbei wird die Stoffbahn mit einem Ende lose auf das meist von Hand in Rotation versetzte Rohr aufgewickelt, das andere Ende der Stoffbahn nimmt demnach keine definierte Lage, da dies für den Transport des Wickels auch nicht erforderlicht ist, ein. Außerdem bilden sich vielfach Falten, so daß ein in dieser Weise hergestellter Wickel für eine Weiterverarbeitung nicht verwendbar ist.Winding rollers for receiving webs of fabric in order to compress them and thus to be able to transport them easily are known in the form of winding tubes made of metal or hard paper. Here, one end of the fabric is loosely wound onto the tube, which is usually rotated by hand, and the other end of the fabric therefore does not assume a defined position, since this is also not required for the transport of the wrap. In addition, folds often form, so that a roll produced in this way cannot be used for further processing.

Durch die US-A-41 20 464 ist eine längeschlitzte Wickelwalze bekannt, die im Walzeninneren beiderseits des Längsschlitzes angeordnete Klemmfedern als Klemmvorrichtung aufweist, in die der durch den Längsschlitz eingeführte Anfang der zu wickelnden Materialbahn einklemmbar und nach Fertigstellung des Wickels herausziehbar ist. Die Klemmfedern sind bei dieser bekannten Wickelwalze mit einem seitlich ausladenden, flachliegend U-förmigen Verbindungsstreifen ausgebildet. Diese Verbindungsstreifen bilden aufgrund der Befestigung der Klemmfedern beiderseits des Längsschlitzes der Wickelwalze einen Einführungsschlitz für den Anfangsbereich der Materialbahn, dessen Breite schmäler als die Materialbahn ist. Infolgedessen eignet sich diese bekannte Wickelwalze nur für Materialbahnen mit einem der Breite des Einführungsschlitzes der Klemmfedern angepaßten Anfangsbreich. Das ist bei Gewebe- oder Folienbahnen aber nicht der Fall.From US-A-41 20 464 a longitudinally slotted winding roller is known which has clamping springs arranged as a clamping device in the inside of the roller on both sides of the longitudinal slot, into which the beginning of the material web to be wound inserted through the longitudinal slot can be clamped and pulled out after completion of the winding. The clamping springs are formed in this known winding roller with a laterally protruding, flat lying U-shaped connecting strip. Due to the fastening of the clamping springs on both sides of the longitudinal slot of the winding roller, these connecting strips form an insertion slot for the initial region of the material web, the width of which is narrower than the material web. As a result, this known winding roller is only suitable for material webs with an initial area adapted to the width of the insertion slot of the clamping springs. However, this is not the case with fabric or film webs.

Eine Wickeiwalze, in die der Anfangsbereich einer Materialbahn über die ganze Breite eingespannt werden kann, ist durch die US-A-38 63-857 bekannt. Die Wickelwalze ist hierbei mehrteilig als Ausdehnungswalze ausgebildet. Sie besteht aus einer Ausdehnungskammer im Inneren eines Zwischenzylinders, die durch entsprechende Druckluftzuführung ausdehnbar oder zusammenziehbar ist. An der Außenwand der Ausdehnungskammer sind durch Bohrungen in dem Zwischenzylinder geführte Befestigungsstutzen für zwei äußere lose Schalenteile aufweisende Tragplatten angeordnet. Die beiden Schalenteile und ein drittes, mit dem Zwischenzylinder fest verbundenes Schalenteil sind unter Zwischenschaltung eines Abstandskörpers im Abstand zum Zwischenzylinder gehalten. Eine weitere Tragplatte an der Außenwand der Ausdehnungskammer trägt eine Druckleiste für den durch einen Schlitz zwischen einem losen und dem festen Schalenteil einzuführenden Anfang der zu wickelnden Materialbahn, der durch Druckluftzuführung in die Ausdehnungskammer an der Innenwand des festen Schalenteiles geklemmt wird, wobei die losen Schalenteile nach außen gedrückt werden, so daß sich die drei Schalenteile zu einem Kreiszylinder ergänzen, auf dessen Außenfläche der Wickel gebildet wird. Diese bekannte Wickelwalze ist ersichtlich sehr kompliziert aufgebaut. Eine Abzugsvorrichtung für die aufgewickelte Bahn ist nicht vorhanden. Das Einführen in den Schlitz dürfte nur bei steifen Materialien problemlos sein.A wrap-around roller, in which the starting area of a material web can be clamped over the entire width, is known from US-A-38 63-857. The winding roller is designed in several parts as an expansion roller. It consists of an expansion chamber inside an intermediate cylinder, which can be expanded or contracted by a corresponding compressed air supply. On the outer wall of the expansion chamber, mounting sockets for two outer loose shell parts are arranged through support holes through bores in the intermediate cylinder. The two shell parts and a third shell part firmly connected to the intermediate cylinder are kept at a distance from the intermediate cylinder with the interposition of a spacer. Another support plate on the outer wall of the expansion chamber carries a pressure bar for the beginning of the material web to be inserted through a slot between a loose and the fixed shell part, which is clamped by compressed air supply into the expansion chamber on the inner wall of the fixed shell part, the loose shell parts following be pressed outside, so that the three shell parts complement each other to form a circular cylinder, on the outer surface of which the winding is formed. This known winding roller is obviously very complicated. A take-off device for the wound web is not available. The insertion into the slot should only be problem-free with stiff materials.

Eine weitere durch die DE-B-12 64 204 bekannte Ausdehnungswickelwalze weist einen einen hohlzylindrischen Füllkörper umgebenden Luftsack im Inneren eines mit Radialdurchbrüchen versehenen Zylinders auf, durch dessen Radialdurchbrüche mit dem Luftsack in Verbindung stehende Druckbolzen zum Abstützen und Verspannen des Kerns einer Papierrolle oder einer Rolle aus anderem Material nach außen treten und zum Abnehmen des Bahnwickels nach innen zurückfallen, wobei der Füllkörper ein zu starkes Zurückfallen verhindert.Another expansion winding roller known from DE-B-12 64 204 has an airbag surrounding a hollow cylindrical filler body inside a cylinder provided with radial openings, through the radial openings of which pressure bolts are connected to the airbag for supporting and tensioning the core of a paper roll or a roll stepping out of other material and falling backwards to remove the web wrap, the packing preventing excessive falling back.

Auch diese bekannte Wickelwalze ist relativ kompliziert aufgebaut, es ist keine Abnahmevorrichtung für die fertigen Bahnwickel vorhanden und es ist auch keine Klemmvorrichtung für den Anfangsbereich einer zu wickelnden Bahn vorgesehen.This known winding roller is also constructed in a relatively complicated manner, there is no removal device for the finished web windings and there is also no clamping device for the initial region of a web to be wound.

Bei keiner der Vorrichtungen nach den Entgegenhaltungen sind im übrigen Vorkehrungen zum faltenfreien Aufwickeln einer Materialbahn getroffen.With none of the devices according to the documents, provisions are otherwise made for the crease-free winding of a material web.

Außer den Vorrichtungen zur Verspannung des Wickels mit der Wickelwalze durch die beiden ersten der vorgenannten Druckschriften ist durch die DE-B-21 28 851 eine Vorrichtung zum Verspannen einer Wickelhülse mit einer Antriebsvorrichtung bekannt, die einen auf einem Wellendende angeordneten, in die Wickelhülse einschiebbaren Spannkopf mit entgegen einer Rückholvorrichtung spreizbaren Spannbacken aufweist. Der Spannkopf dient lediglich zum Herstellen einer Antriebsverbindung zwischen der antreibenden Welle und der Wickelhülse.In addition to the devices for tensioning the winding with the winding roller by the first two of the aforementioned documents, DE-B-21 28 851 discloses a device for tensioning a winding tube with a drive device which has a tensioning head which is arranged on a shaft end and can be inserted into the winding tube with jaws that can be expanded against a return device. The clamping head only serves to establish a drive connection between the driving shaft and the winding tube.

Aufgabe der Erfindung ist es daher, eine Einrichtung zum Wickeln von flächigen Stoff- oder Folienbahnen zu schaffen, die als Wickel in einer Verarbeitungsanlage nicht nur leicht zu den einzelnen Arbeitsstationen zu transportieren ist, sondern deren Kanten im aufgewickelten Zustand auch bearbeitet, z. B. gesäumt oder geschweißt werden können, da der Abstand zu dem Wickelrohr stets exakt einstellbar ist. Außerdem soll erreicht werden, daß das Aufwickeln ohne Schwierigkeiten in kurzer Zeit vorzunehmen ist und daß dabei keine Falten entstehen. Auch soll die Abnahme eines Wickels von der Wickelwalze leicht zu bewerkstelligen sein.The object of the invention is therefore to provide a device for winding flat fabric or film webs, which is not only easy to transport as a winding in a processing system to the individual workstations, but also processes the edges thereof in the wound state, e.g. B. can be hemmed or welded, since the distance to the winding tube is always exactly adjustable. In addition, it should be achieved that the winding is to be carried out without difficulty in a short time and that no wrinkles occur. The removal of a roll from the winding roller should also be easy to accomplish.

Gemäß der Erfindung wird dies dadurch erreicht, daß die vorzugsweise auf zwei mit seitlichem Abstand zueinander angeordneten Stützwalzen abgestützte Wickelwalze in ihrer Länge zweigeteilt und der eine Teil als axial verschiebbare, mit einem über den anderen Teil überstehenden Wikkelbereich der zu wickelnden Bahn von innen verspannbare Abzugsvorrichtung ausgebildet ist, die eine Freisparung als Fortsetzung der Längsnut für den Durchtritt eines höhenverstellbaren Schwertes zum teilweisen Einführen der Bahn in die Klemmvorrichtung aufweist.According to the invention, this is achieved in that the winding roller, which is preferably supported on two support rollers arranged at a lateral distance from one another, is divided in two in length and one part is designed as an axially displaceable pull-off device which can be braced from the inside with a winding region of the web to be wound which projects beyond the other part is a cutout as a continuation of the longitudinal groove for the passage of a height-adjustable sword for partial insertion of the web in the clamping device.

Zur Abnahme des Wickels ist es ferner angebracht, die Abzugsvorrichtung aus einem mit einem Einsatzstück versehenen, mit diesem in die Wickelwalze einsetzbaren, axial verstellbar angeordneten Spannkopf zu bilden, der nach Art einer Spannzange mit der Innenmantelfläche des Wickeis verspannbar ist.To remove the winding, it is also appropriate to form the take-off device from an axially adjustable clamping head provided with an insert piece which can be inserted into the winding roller and which can be clamped to the inner circumferential surface of the wick in the manner of a collet.

Um dies in einfacher Weise vornehmen zu können, sollte der Spannkopf mehrere sich vorzugsweise in Achsrichtung erstreckende Durchbrechungen aufweisen und in diesem sollte ein aufblasbarer Schlauch oder ein ähnl. durch Druckmittel verformbarer und durch die Durchbrüche austretender Einsatz eingesetzt sein, mittels dem der Wickel mit dem Spannkopf verspannbar ist. Des weiteren ist es hierbei angebracht, daß der im Spannkopf angeordnete verformbare Einsatz aus zwei beiderseits der Freisparung gehaltenen aufblasbaren Teilen hergestellt ist, die über eine Verteilerkammer an eine gemeinsame Druckmittelzuführungsleitung angeschlossen sind.In order to be able to do this in a simple manner, the clamping head should have a plurality of openings which preferably extend in the axial direction and in this an inflatable tube or the like should be provided. insert which can be deformed by pressure medium and emerges through the openings, by means of which the winding can be clamped with the clamping head. Furthermore, it is appropriate here that the deformable insert arranged in the clamping head is made of two inflatable parts held on both sides of the clearance, which are connected via a distributor chamber to a common pressure medium supply line.

Die Klemmvorrichtung der Wickelwalze kann in unterschiedlicher Weise ausgebildet werden, und zwar durch eine in diese eingesetzte geschlitzte Klemmhülse, die im Bereich der in die Wickelwalze eingearbeiteten Längsnut nach innen abgewinkelte federnde Arme aufweist, durch mehrere in die Wickelwalze eingesetzte geschlitzte Federringe, die an einem in der Wickelwalze angeordneten Käfig befestigt und im Bereich der in diese eingearbeiteten Längsnut mit nach innen abgewinkelten federnden Armen versehen sind oder durch zwei vorzugsweise winkelig ausgebildete, drehbar gelagerte und durch Federkraft gegeneinander verspannbare Klemmleisten, die im Bereich der in die Wickelwalze eingearbeiteten Längsnut angeordnet sind. Nach einer weiteren Ausgestaltung kann die Klemmvorrichtung der Wickelwalze auch aus zwei beiderseits der in diese eingearbeiteten Längsnut angeordneten gemeinsam aufblasbaren Schläuchen oder ähnl. von Druckmittel verformbaren Einsätzen gebildet werden. Mittels des Schwertes kann somit ohne Schwierigkeiten ein Teil der aufzuwickelnden Bahn zwischen die federnden Arme der Klemmhülse oder der Federringe bzw. die Klemmleiste oder die aufblasbaren Schläuche eingeführt werden.The clamping device of the winding roller can be designed in different ways, namely by a slotted clamping sleeve inserted into it, which in the area of the longitudinal groove worked into the winding groove has inwardly angled resilient arms, by several slotted spring washers inserted into the winding roller, which are attached to one in the cage arranged and fastened in the area of the incorporated longitudinal groove with inwardly angled resilient arms or by two preferably angled, rotatably mounted and by spring force clamped against each other, which are arranged in the area of the longitudinal groove incorporated in the winding roller. According to a further embodiment, the clamping device of the winding roller can also consist of two inflatable tubes or the like arranged on both sides of the longitudinal groove worked into this. inserts which can be deformed by pressure medium. By means of the sword, part of the web to be wound can thus be inserted between the resilient arms of the clamping sleeve or the spring washers or the clamping strip or the inflatable tubes without difficulty.

Die gemäß der Erfindung ausgebildete Einrichtung zum Wickeln von flächigen Stoff- oder Folienbahnen ist nicht nur einfach in der konstruktiven Ausgestaltung und somit auf wirtschaftliche Weise herstellbar, sondern auch vielseitig verwendbar, funktionssicher und leicht zu handhaben. Wird nämlich die aufzuwickelnde Bahn mittels einer in der Wickelwalze angeordneten Klemmvorrichtung mit dieserverspannt, so ist es möglich, die Wickelwalze während des Wickelns mit hoher Geschwindigkeit anzutreiben und somit Wickel in kurzer Zeit herzustellen, ohne daß sich dabei Falten bilden. Auch kann, wird die aufzuwickelnde Bahn etwa in der Mitte eingespannt, eine doppelte Wicklung vorgenommen werden.The device designed according to the invention for winding flat fabric or film webs is not only simple in its structural design and thus economical to manufacture, but also versatile, reliable and easy to handle. Namely, if the web to be wound is tensioned with it by means of a clamping device arranged in the winding roller, it is possible to drive the winding roller at high speed during winding and thus to produce windings in a short time without wrinkles being formed. A double winding can also be carried out if the web to be wound is clamped approximately in the middle.

Außerdem wird die Stoff- oder Folienbahn äußerst fest gewickelt. Vor allem aber ist von großem Vorteil, daß deren Kanten nach vorgegebenen Voll- und/oder Teilumdrehungen der Wickelwalze in eine stets definierte Lage gebracht werden und somit in einer oder mehreren Arbeitsstationen bearbeitet werden können. Auf diese Weise wird der Transport flächiger Gebilde, da diese auf kleinem Raum kompakt zusammengepreßt sind, erheblich erleichtert, auch werden Führungsmittel sowie Bauraum eingespart. Die mittels der erfindungsgemäß ausgebildeten Einrichtung hergestellten Wickel sind demnach vielseitig, zumal diese mittels der Abzugsvorrichtung rasch von der Wickelwalze abzunehmen sind, verwendbar.In addition, the fabric or film web is wrapped extremely tight. Above all, however, it is of great advantage that their edges are brought into a constantly defined position after predetermined full and / or partial revolutions of the winding roller and can thus be processed in one or more workstations. In this way, the transport of flat structures, since they are compactly compacted in a small space, is made considerably easier, and guide means and installation space are also saved. The windings produced by means of the device designed according to the invention are therefore versatile, especially since they can be quickly removed from the winding roller by means of the take-off device.

Um dies zu bewerkstelligen, ist die Wickelwalze 11 mit einer Längsnut 12 versehen, durch die mit Hilfe eines höhenverstellbaren Schwertes 3 das betreffende Teil der abgelenkten Bahn 2 in die Klemmvorrichtung 21 eingeführt werden kann. Die Wickelwalze 11 ist auf Stützwalzen 13, denen Apreßrollen 14 zugeordnet sind und durch die die Bahn 2 geführt wird, gehalten.The device shown in FIG. 1 and designated 1 for winding a flat fabric or film web 2 consists of a rotationally drivable winding roller 11 and a clamping device 21 inserted therein, by means of which the web 2 can be connected with the central part 2 'or with one of the both end parts 2 "or 2" 'can be clamped. To accomplish this, the winding roller 11 is provided with a longitudinal groove 12 through which the part of the deflected web 2 in question can be inserted into the clamping device 21 with the aid of a height-adjustable sword 3. The winding roller 11 is held on support rollers 13, which are assigned press rollers 14 and through which the web 2 is guided.

Die Klemmvorrichtung 21 besteht bei dem Ausführungsbeispiel nach Fig. 1 aus einer in der Wickelwalze 11 angeordneten geschlitzten Klemmhülse 22, die in Bereich der Längsnut 12 nach innen abgewinkelte federnde Arme 23 und 24 aufweist. Mittels des Schwertes 3 wird somit das Teil 2' - oder eines der Endteile 2" bzw. 2'" - leicht zwischen die federnden Arme 23 und 24 eingeführt werden, so daß auf einfache Weise eine Verspannung der Bahn 2 mit der Wickelwalze 11 zu bewerkstelligen ist.In the exemplary embodiment according to FIG. 1, the clamping device 21 consists of a slotted clamping sleeve 22 which is arranged in the winding roller 11 and which has resilient arms 23 and 24 which are angled inwards in the region of the longitudinal groove 12. By means of the sword 3, the part 2 '- or one of the end parts 2 "or 2'" - is easily inserted between the resilient arms 23 and 24, so that tensioning of the web 2 with the winding roller 11 can be accomplished in a simple manner is.

Gemäß Fig. 2 besteht die in der Wickelwalze 11 angeordnete Klemmvorrichtung 31 aus mehreren mit seitlichem Abstand zueinander angeordneten Federringen 32, die im Bereich der Längsnut 12 ebenfalls nach innen abgewinkelte federnde Arme 33 und 34 aufweisen. Die Federringe 32 sind mittels Nieten 36 oder auf ähnliche Weise an einem Käfig 35 befestigt, der mit der Wickelwalze 11 lageorientiert verbunden ist. Das jeweilige Teil der einzuspannenden Bahn wird bei der Klemmvorrichtung 31 im Gegensatz zu der Klemmvorrichtung 21 somit nicht auf der gesamten Länge, sondern nur abschnittweise von den federnden Armen 33 und 34 gehalten, so daß dieses leicht und nur mit einem geringen Kraftaufwand wiederum herauszunehmen ist.2, the clamping device 31 arranged in the winding roller 11 consists of a plurality of spring rings 32 which are arranged at a lateral distance from one another and which also have resilient arms 33 and 34 which are angled inwards in the region of the longitudinal groove 12. The spring rings 32 are fastened by means of rivets 36 or in a similar manner to a cage 35 which is connected to the winding roller 11 in a positionally oriented manner. The respective part of the web to be clamped in the clamping device 31, in contrast to the clamping device 21, is thus not held over the entire length, but only in sections by the resilient arms 33 and 34, so that it can be removed again easily and with little effort.

Die Klemmvorrichtung 41 nach Fig. 3 besteht aus zwei winkelig geformten und im Bereich der Längsnut 12 der Wickelwalze 11 angeordneten Klemmleiste 42 und 43, die mittels Bolzen 44 bzw. 45 drehbar an einem oder mehreren mit Abstand zueinander angebrachten Halteringen 46 abgestützt sind. Durch die nach innen gerichteten Schenkel der Klemmleiste 42 und 43 wird das in die Wickelwalze 11 eingeführte Teil der Bahn zusammengepreßt und somit festgehalten, da auf deren außere Schenkel jeweils eine Zugfeder 47 bzw. 48 einwirkt, die an dem Haltering 46 befestigt ist.3 consists of two angularly shaped clamping strips 42 and 43 which are arranged in the region of the longitudinal groove 12 of the winding roller 11 and which are rotatably supported by means of bolts 44 and 45 on one or more retaining rings 46 arranged at a distance from one another. Due to the inwardly directed legs of the terminal block 42 and 43, the part of the web introduced into the winding roller 11 is pressed together and thus held in place, since a tension spring 47 or 48 acts on the outer leg, which is fastened to the retaining ring 46.

Nach den Fig. 4 und 5 ist die Klemmvorrichtung 51 aus zwei aufblasbaren Schläuchen 52 und 53 gebildet, die beiderseits der Längsnut 12 in die Wickelwalze 11 eingesetzt sind. Über Düsen 54 und 55, die an eine gemeinsame Druckkammer 56 angeschlossen sind, ist den Schläuchen 52 und 53 gesteuert Druckluft zuführbar, so daß, sobald ein Teil der einzuspannenden Bahn sich zwischen diesen befindet, diese aufgeblasen werden können. Die sich durch das Aufblasen der Schläuche 52 und 53 ergebende Lage ist in Fig. 4 strichpunktiert eingezeichnet.4 and 5, the clamping device 51 is formed from two inflatable tubes 52 and 53 which are inserted into the winding roller 11 on both sides of the longitudinal groove 12. Compressed air can be supplied to the tubes 52 and 53 in a controlled manner via nozzles 54 and 55, which are connected to a common pressure chamber 56, so that as soon as a part of the web to be tensioned is between them, these can be inflated. The position resulting from the inflation of the tubes 52 and 53 is shown in broken lines in FIG. 4.

Die Zuführung der Druckluft in die Druckkammer 56 erfolgt über einen in den Lagerzapfen 4 der Wickelwalze 11 eingearbeiteten Druckmittelzuführungskanal 57 von einer nicht dargestellten Druckmittelquelle. Zum Antrieb der mittels des Zapfens 4 und eines Wälzlagers 5 in einem Gehäuse 6 drehbar gelagerten Wickelwalze 11 dient. ein schematisch dargestellter Antriebsmotor 7, durch den diese gesteuert antreibbar ist.The compressed air is fed into the pressure chamber 56 via a pressure medium supply channel 57, which is incorporated into the bearing journal 4 of the winding roller 11, from a pressure medium source (not shown).

Um einen Wickel von der Wickelwalze 11 rasch und auf einfache Weist abnehmen zu können, ist eine Abzugsvorrichtung 61 vorgesehen, die in den Fig. 6 und 7 dargestellt ist und aus einem nach Art einer Spannzange ausgebildeten Spannkopf 62 besteht, der mit einem Ende der kürzer als die Breite der zu wickelnden Bahn ausgebildeten Wickelwalze 11 verbunden wird und die Wickelwalze 11 bis etwa auf die Breite der zu wickelnden Bahn 2 ergänzt, um ein von der Abzugsvorrichtung innen ergreifbares Wickelteil zu erhalten.In order to be able to remove a winding from the winding roller 11 quickly and in a simple manner, a take-off device 61 is provided, which is shown in FIGS. 6 and 7 and consists of a clamping head 62 designed in the manner of a collet and having one end of the shorter one when the width of the winding roller 11 to be wound is connected and the winding roller 11 is expanded to approximately the width of the web to be wound 2 in order to obtain a winding part which can be gripped from the inside by the take-off device.

In dem mit einer zu der Längsnut 12 der Wickelwalze 11 fluchtenden Freisparung 67, in die das Schwert 3 mit einem Ende einführbar ist, versehenen Spannkopf 62 ist ein verformbarer Einsatz 64 angeordnet, der als aufblasbare Schlauchteile 65 und 66 ausgebildet ist. Außerdem sind in den Spannkopf 62 sich in Achsrichtung erstreckende Durchbrüche 63 eingearbeitet, aus denen, wie dies strichliniert in Fig. 7 gezeigt ist, die Schlauchteile 65 und 66 heraustreten können. Im aufgeblasenen Zustand der Schlauchteile 65 und 66 ist somit der Spannkopf 62 mit dem Wickel verspannt, so daß dieser leicht von der Wickelwalze 11 durch eine Axialverschiebung abgenommen werden kann.In the clamping head 62, which is aligned with the longitudinal groove 12 of the winding roller 11 and into which the sword 3 can be inserted at one end, a deformable insert 64 is arranged, which is designed as an inflatable tube parts 65 and 66. In addition, openings 63 extending in the axial direction are machined into the clamping head 62, from which, as shown in broken lines in FIG. 7, the hose parts 65 and 66 can emerge. In the inflated state of the hose parts 65 and 66, the tensioning head 62 is thus clamped to the winding so that it can be easily removed from the winding roller 11 by an axial displacement.

Das eingespannte Teil der aufgewickelten Bahn wird dabei aus der Klemmvorrichtung gelöst.The clamped part of the wound web is released from the clamping device.

Zur Druckmittelzuführung ist in den mittels eines Wälzlagers 74 in einem Bauteil 75 drehbar gelagerten Zapfen 72 des Spannkopfes 62, auf dem mit Hilfe eines in diesen eingesetzten Einsatzstückes 71 die Wickelwalze 11 mit ihrem freien Ende abgestützt ist, ein an eine nicht dargestellte Druckmittelquelle angeschlossener Kanal 70 eingearbeitet, über den Druckmittel in eine Sammelkammer 68 einbringbar ist, aus der dieses über Düsen 69 den Schlauchteilen 65 und 66 zuströmen kann. Zur Axialverschiebung des Spannkopfes 62 sowie zu dessen Verdrehung gegenüber der Wickelwalze 11 nach Abnahme eines Wickels ist eine schematisch eingezeichnete Servoeinrichtung 73 vorgesehen, mittels der nach Beendigung eines Wickelvorganges der Spannkopf 62 zusammen mit dem fest gespannten Wickel zunächst nach links, um die Verbindung zwischen diesem und der Wickelwalze 11 zu lösen, verschoben und nachfolgend gegenüber dieser verdreht wird, um den Wickel beispielsweise einer Arbeitsstation zuzuführen.For the supply of pressure medium, a channel 70 connected to a pressure medium source (not shown) is connected to the pin 72 of the clamping head 62, which is rotatably mounted in a component 75 by means of a roller bearing 74 and on which the winding roller 11 is supported with the aid of an insert 71 inserted therein incorporated, via which pressure medium can be introduced into a collecting chamber 68, from which the hose parts 65 and 66 can flow via nozzles 69. For the axial displacement of the tensioning head 62 and for its rotation with respect to the winding roller 11 after removal of a winding, a schematically drawn servo device 73 is provided, by means of which after the end of a winding process the tensioning head 62 together with the firmly tensioned winding initially to the left in order to establish the connection between it and to loosen the winding roller 11, shifted and subsequently rotated relative to this in order to feed the winding to a work station, for example.
