Description

Die Erfindung bezieht sich auf eine Wickelvorrichtung wie sie im Oberbegriff des Hauptanspruches angegeben ist.The invention relates to a winding device as specified in the preamble of the main claim.

Bekannte Wickelvonichtungen verwenden Wickelköpfe, an denen der Anfang des Wickeigutes vor dem Wickelvorgang von Hand festgeklemmt werden muß. Als Klemmeinrichtung werden bei den bekannten Wickelköpfen keilförmige Ausschnitte am Wickelkem vorgesehen, in die der jeweilige Anfang des Wickelgutes eingeschoben und festgeklemmt wird. Die aufgewickelten Kabel-, Schlauch- oder Profilringe, die von Hand oder mit Motorantrieb aufgewickelt wurden, müssen nun wieder manuell entnommen werden. Diese manuellen Arbeiten sind zeitaufwendig und monoton.Known winding devices use winding heads on which the beginning of the material to be wound must be clamped by hand before the winding process. In the known winding heads, wedge-shaped cutouts are provided on the winding core as a clamping device, into which the respective beginning of the winding material is inserted and clamped. The coiled cable, hose or profile rings that have been coiled by hand or with a motor drive must now be removed manually. This manual work is time consuming and monotonous.

Bekannt ist auch bereits eine Wickelvorrichtung (EP-A1-0 049 552), mit einem Wickelkopf, der einen mehrteiligen Wickelkem aufweist wobei von den aus Einzelstreben bestehenden Seitenflanschen der eine zusammenklappbar und in den Wickelkem einschiebbar ist. Das Spreizen bzw. Verjüngen des Wickelkems erfolgt beim Zusammenklappen der den Flansch bildenden Einzelelemente, der Antrieb erfolgt von hier aus, Störungen sind bei dieser bekannten Wickeivorrichtung beim Abwurf des Wickelgutes vom Wickelkem durch das noch nach außen ragende Gestänge zu erwarten. Darüberhinaus läßt die bekannte Vorrichtung nicht erkennen, in welcher Art und Weise das freie Ende des Wickelgutes zu Beginn des Wickelvorganges gehalten werden kann. Das ist aber entscheidend, wenn man, wie bei Kabeln und Leitungen, also flexiblem Wickelgut, erhöhte Wickelgeschwindigkeiten anstrebt.A winding device (EP-A1-0 049 552) with a winding head which has a multi-part winding core is also already known, one of the side flanges consisting of individual struts being collapsible and insertable into the winding core. The spreading or tapering of the winding core takes place when the individual elements forming the flange are collapsed, the drive takes place from here, malfunctions are to be expected in this known winding device when the winding material is ejected from the winding core due to the rod which still protrudes outwards. In addition, the known device does not reveal the manner in which the free end of the material to be wound can be held at the start of the winding process. However, this is crucial if, like with cables and wires, i.e. flexible material to be wound, the aim is to increase winding speeds.

Eine andere bekannte Wickelvorrichtung (GB-A1-1102 770) sieht zwei seitliche Spulenflansche vor sowie einen Spulenkern aus drei in Achsrichtung geführten Stangen, die zum Abnehmen des Wickelgutes mittels vorgegebener Nuten in radialer Richtung parallel zueinander verschoben werden. Auch hier ist ein kurzfristiges Abwerfen des Wickelbundes zur Anpassung an hohe Wickelgeschwindigkeiten ebensowenig möglich wie ein definiertes Halten des Wickelgutendes.Another known winding device (GB-A1-1102 770) provides two lateral coil flanges and a coil core made of three rods guided in the axial direction, which are displaced in the radial direction parallel to one another by means of predetermined grooves in order to remove the winding material. Here too, a short-term ejection of the winding bundle to adapt to high winding speeds is just as impossible as a defined holding of the end of the winding material.

Hier helfen auch nicht andere bekannte Vorrichtungen (EP-Ai-0101 134 und GB-A-105 682) weiter bei denen im festen Spulenkem einer Wickelvorrichtung mit festgelegten Flanschen ein innerer Kem einschiebbar ist, dessen Einzelelemente radial nach außen bewegbar sind bzw. an einer Bodenplatte Winkelprofile angelängt sind, die von Hand alle gemeinsam nach innen oder nach außen geschwenkt werden können.Other known devices (EP-Ai-0101 134 and GB-A-105 682) do not help here either, in which an inner core can be inserted in the fixed core of a winding device with fixed flanges, the individual elements of which can be moved radially outwards or on one Bottom plate angle profiles are attached, which can all be swiveled inwards or outwards by hand.

Ausgehend von diesem Stand der Technik, liegt der Erfindung die Aufgabe zugrunde eine motorgetriebene Wickelvorrichtung zu schaffen, mit der eine Verarbeitung des Wickelgutes zumindest weitgehend maschinell durchgeführt werden kann.Starting from this prior art, the invention has for its object to provide a motor-driven winding device with which processing of the winding material can be carried out at least largely by machine.

Die Lösung dieser Aufgabe wird bei einer Wickelvorrichtung der eingangs genannten Art durch die im Kennzeichen des Hauptanspruches angegebenen Merkmale erhalten. Durch die abnehmbare Befestigung des zweiten Seitenflansches ist ein problemloses Herunterrutschen oder Herunterfallen des Wickelgutes vom verjüngten Kern gewährleistet, eine Behinderung dieses Abwurfes im Wickelkembereich tritt nicht auf. Erhöhte Wickelgeschwindigkeiten gegenüber dem Stand der Technik ergeben sich bei der Erfindung auch dadurch, daß beim Lösen des zweiten Seitenflansches vom Wickelkern sich dieser durch Antrieb der Einzelelemente vom ersten Seitenflansch her zu den freien Enden hin verjüngt und mit dem Lösen des Seitenflansches dieser den zwischen dem zweiten Seitenflansch und dem freien Ende eines Einzelsegmentes festklemmbaren Anfang des Wickelgutes freigibt.The solution to this problem is obtained in a winding device of the type mentioned by the features specified in the characterizing part of the main claim. The removable attachment of the second side flange ensures that the winding material can easily slide down or fall off the tapered core, and there is no obstruction to this release in the winding core area. Increased winding speeds compared to the prior art also result in the invention in that when the second side flange is detached from the winding core, it tapers by driving the individual elements from the first side flange to the free ends, and when the side flange is released, the latter between the second Side flange and the free end of a single segment clampable beginning of the winding material releases.

Die Einzelsegmente des Kernes des Wickelkopfes können mittels eines pneumatischen oder hydraulischen Antriebs gemeinsam verschwenkt werden. Eine automatische Entnahme des Wickelgutes kann durch eine Schwenkeinrichtung sichergestellt werden, mit der der erste Seitenflansch und damit der Wickelkem nach vorne geschwenkt wird, so daß das Wickelgut abfällt. Die Klemmeinrichtung, die den Anfang des Wickelgutes während des Wickelvorgangs festhält, öffnet sich beim Abnehmen des zweiten Seitenflansches.The individual segments of the core of the winding head can be pivoted together by means of a pneumatic or hydraulic drive. Automatic removal of the material to be wound can be ensured by means of a pivoting device with which the first side flange and thus the winding core is pivoted forward so that the material to be wound falls off. The clamping device, which holds the start of the material to be wound during the winding process, opens when the second side flange is removed.

Die Klemmeinrichtung ist bevorzugt so ausgebildet, daß an wenigstens einem der Einzelsegmente im Bereich ihrer dem zweiten Seitenflasch zugewandten Enden eine Aussparung vorgesehen ist, in die der Anfang des Wickelgutes hineinragt, und daß am zweiten Seitenflansch wenigsten ein federndes Klemmelement angeordnet ist, welches bei aufgestecktem zweiten Seitenflansch den Wickelgutanfang in der Aussparung verklemmt. Der Wickelgutanfang wird dabei am Rand der Aussparung angedrückt.The clamping device is preferably designed such that a recess is provided in at least one of the individual segments in the region of its ends facing the second side bottle, into which the beginning of the winding material protrudes, and that at least one resilient clamping element is arranged on the second side flange, which element is attached when the second one is attached Side flange jammed the beginning of the material to be wound in the recess. The beginning of the material to be wound is pressed onto the edge of the recess.

Zum Aufstecken und Abnehmen des zweiten Seitenflansches ist vorgesehen daß der zweite Seitenflansch auf einer Verschiebeeinheit axial verschiebbar befestigt ist und daß die Verschiebeeinheit ein mittels eines Pneumatikzylinders parallel zur Rotationsachse des Wickelkopfes verschiebbares Traggestell besitzt, an dem der zweite Seitenflansch drehhar gelagert ist. Zum Festhalten des Wickelkopfes kann der zweite Seitenflansch mit einer elektromagnetischen Bremseinrichtung versehen sein.To attach and remove the second side flange, it is provided that the second side flange is axially displaceably fastened on a displacement unit and that the displacement unit has a support frame which can be displaced by means of a pneumatic cylinder parallel to the axis of rotation of the winding head and on which the second side flange is rotatably mounted. To hold the winding head, the second side flange can be provided with an electromagnetic braking device.

Die schwenkbaren Einzelsegmente des ersten Seitenflansches sind so angeordnet, daß beim Aufstecken des zweiten Seitenflansches diese über Gelenklaschen nach außen gedrückt werden, bis die Oberfläche des Wickelkems parallel zur Rotationsachse verläuft Wird der zweite Seitenflansch nach Beendigung des Wickelvorganges abgenommen, drückt eine Spiralfeder die schwenkbaren Einzelsegmente wieder nach innen. Die Schwenkgelenke der Einzelsegmente befinden sich außerhalb des Wickelkems.The swiveling individual segments of the first side flange are arranged in such a way that when the second side flange is attached, they are pressed outwards via hinge plates until the surface of the winding core runs parallel to the axis of rotation inside. The swivel joints of the individual segments are located outside the winding core.

Die Antriebswelle des ersten Seitenflansches ist mit der seitlichen Scheibe, die den Wickelkem einseitig begrenzt starr verbunden und ragt in das Innere des Wickelkerns hinein. Dort ist auf der Antriebswelle eine gleitend gelagerte Buchse angeordnet, die über Gelenklaschen mit den Einzelsegmenten verbunden ist. Wird die Buchse gegen eine Federkraft nach innen zu der genannten Scheihe gedrückt, so werden dadurch die Einzelsegmente üher die Gelenklaschen nach außen gedrückt, bis die Oberfläche des Wickelkems parallel zur Antriebswelle verläuft Die auf der Antriebswelle befindliche Buchse wird von einer ebenfalls federnd gelagerten zweiten Buchse des zweiten Seitenflansches beim Aufsetzen des zweiten Seitenflansches betätigt.The drive shaft of the first side flange is rigidly connected to the side disk that limits the winding core on one side and projects into the interior of the winding core. There is a slidably mounted bushing on the drive shaft, which is connected to the individual segments by means of link plates. If the bushing is pressed inwards against the spring by a spring force, the individual segments are pushed outwards via the joint plates until the surface of the winding core runs parallel to the drive shaft. The bushing on the drive shaft is supported by a second bushing, which is also spring-mounted second side flange actuated when placing the second side flange.

Der für den Antrieb des Wickelkopfes vorgesehene Motor ist vorzugsweise ein Schritt-Motor, mit dem ein exaktes Positionieren der für die Aufnahme des Wickelgut-Anfanges vorgesehenen Aussparungen vorgenommen werden kann. Auf diese Weise ist es möglich, den einzufädelnden Anfang des Wickelgutes mechanisch mittels eines Greifarmes in die Aussparung am Wickelkopf einzuführen. Anschließend wird der zweite Seitenflansch beispielsweise mittels eines pneumatischen Antriebs in axialer Richtung auf den ersten Seitenflansch aufgesteckt. Damit die am zweiten Seitenflansch angeordneten Klemmelemente und die Aussparungen des ersten Seitenflansches immer übereinstimmen, wird der zweite Seitenflansch mittels einer Bremseinrichtung in der entsprechenden Position gehalten, so daß er sich während der axialen Verschiebungen nicht drehen kann.The motor provided for driving the winding head is preferably a stepping motor with which the recesses provided for receiving the start of the material to be wound can be positioned exactly. In this way, it is possible to mechanically insert the beginning of the winding material to be threaded into the recess on the winding head by means of a gripper arm. The second side flange is then slipped onto the first side flange in the axial direction, for example by means of a pneumatic drive. So that the clamping elements arranged on the second side flange and the recesses of the first side flange always match, the second side flange is held in the corresponding position by means of a braking device, so that it cannot rotate during the axial displacements.

Vorteilhafte Weiterbildungen der Erfindung sind in den übrigen Unteransprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the remaining subclaims.

Der Gegenstand der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen :

  • Figur 2 den ersten Seitenflansch im Schnitt,
  • Figur 3 einen Ausschnitt aus der Draufsicht des in Figur 2 dargestellten Seitenflansches und
  • Figur 4 den zweiten Seitenflansch in Verbindung mit dem andeutungsweise dargestellten ersten Seitenflansch im Schnitt.
The object of the invention is explained in more detail with reference to the drawings. Show it :
  • 1 shows a winding device with a two-part winding head consisting of a first and a second side flange,
  • FIG. 2 shows the first side flange in section,
  • Figure 3 shows a detail from the top view of the side flange shown in Figure 2 and
  • Figure 4 shows the second side flange in connection with the first side flange shown in section.

Bei der in Figur 1 dargestellten Wickelvorrichtung ist auf einer Grundplatte 1 eine Verschiebeeinheit 2 und eine Schwenkeinrichtung 3 montiert. An einer Schwenkachse 4 der Schwenkeinrichtung 3 ist ein hier nur andeutungsweise dargestellter erster Seitenflansch 5 eines Wickelkopfes 6 gelagert. Der erste Seitenflansch 5 wird von einem Schritt-Motor 7 angetrieben. An der Schwenkachse 4 ist ein Schwenkarm 8 angebracht, der mittels eines Zylinders 9 betätigbar ist. Der Schwenkarm 8 läßt sich von dem Zylinder 9 nach oben beispielsweise um einen Winkel a = 50° nach oben schwenken, so daß der erste Seitenflansch 5 nach vorne gekippt wird. Ein auf dem hier nicht dargestellten Wickelkern des ersten Seitenflansches befindliches Wickelgut kann auf diese Weise vom Seitenflansch 5 abgeworfen werden.In the winding device shown in FIG. 1, a displacement unit 2 and a swivel device 3 are mounted on a base plate 1. A first side flange 5 of a winding head 6, which is only indicated here, is mounted on a pivot axis 4 of the pivot device 3. The first side flange 5 is driven by a stepping motor 7. A pivot arm 8 is attached to the pivot axis 4 and can be actuated by means of a cylinder 9. The swivel arm 8 can be swiveled upward from the cylinder 9, for example by an angle a = 50 °, so that the first side flange 5 is tilted forward. A winding material located on the winding core (not shown here) of the first side flange can be thrown off the side flange 5 in this way.

Die Verschiebeeinheit 2 besteht im wesentlichen aus einem Traggestell 10, welches parallel zur Antriebsachse des ersten Seitenflansches 5 mittels eines Zylinders 11 verschiebbar ist. Als Führungselemente sind in der Zeichnung für die axiale Verschiebung des Traggestelles 10 zwei Führungsstäbe 12 dargestellt. Am oberen Ende des Traggestelles 10 ist der zweite Seitenflansch 13 des Wickelkopfes 6 drehhar gelagert, der jedoch in jeder beliebigen Stellung mittels einer elektromagnetischen Bremse 14 arretiert bzw. festgehalten werden kann.The displacement unit 2 consists essentially of a support frame 10 which can be displaced parallel to the drive axis of the first side flange 5 by means of a cylinder 11. Two guide rods 12 are shown as guide elements in the drawing for the axial displacement of the support frame 10. At the upper end of the support frame 10, the second side flange 13 of the winding head 6 is rotatably mounted, which, however, can be locked or held in any position by means of an electromagnetic brake 14.

Die beiden Seitenflansche 5 und 13 sind hier nur andeutungsweise dargestellt und befinden sich in der geöffneten Stellung, da der zweite Seitenflansch 13 vom ersten Seitenflansch 5 abgezogen ist. Mittels des Zylinders 11 kann der zweite Seitenflansch 13 in die hier nicht dargestellte Stellung verbracht und auf den ersten Seitenflansch 5 aufgeschoben werden.The two side flanges 5 and 13 are only indicated here and are in the open position, since the second side flange 13 has been withdrawn from the first side flange 5. By means of the cylinder 11, the second side flange 13 can be brought into the position (not shown here) and pushed onto the first side flange 5.

In Figur 2 ist insbesondere der Aufbau des ersten Seitenflansches 5 ersichtlich. Dieser besteht im wesentlichen aus einer seitlichen Scheibe 15 und dem Wickelkern 16, der einseitig von der Scheibe 15 begrenzt wird. Der zweite Seitenflansch 13 ist in Figur 2 mit unterbrochener Linie andeutungsweise dargestellt.The structure of the first side flange 5 can be seen in particular in FIG. This consists essentially of a lateral disc 15 and the winding core 16 which is delimited on one side by the disc 15. The second side flange 13 is shown in FIG. 2 with a broken line.

Der Wickelkern 16 des ersten Seitenflansches 5 besteht aus mehreren Einzelsegmenten 17, 18, 19, die sich hier in der nach innen geschwenkten Stellung befinden, wie sie bei abgezogenem zweiten Seitenflansch 13 auftritt. Befindet sich der zweite Seitenflansch 13 dagegen in der mit unterbrochenen Linien dargestellten Stellung, so werden die Einzelsegmente 17 bis 19 in die mit unterbrochenen Linien dargestellte Stellung 20 gebracht.The winding core 16 of the first side flange 5 consists of a plurality of individual segments 17, 18, 19, which are here in the inwardly pivoted position, as occurs when the second side flange 13 is removed. However, if the second side flange 13 is in the position shown with broken lines, the individual segments 17 to 19 are brought into the position 20 shown with broken lines.

Die Einzelsegmente 17 bis 19 sind auf Streben 21 befestigt, die schwenkbar in Schwenkgelenken 22 am Seitenflansch gelagert sind. Im Abstand von den Schwenkgelenken 22 sind an den Streben 21 Gelenklaschen 23 befestigt, die mit ihrem anderen Ende an einer achsial verschiebbaren Buchse 24 befestigt sind. Die Buchse 24 sitzt auf einer Verlängerung 25 der Antriebswelle 26, die sich in das Innere des Wickelkerns 16 erstreckt. Mittels einer Spiralfeder 27 stützt sich die Buchse 24 federnd gegenüber der Scheibe 15 ab.The individual segments 17 to 19 are attached to struts 21 which are pivotally mounted in pivot joints 22 on the side flange. At a distance from the swivel joints 22, joint straps 23 are fastened to the struts, the other ends of which are fastened to an axially displaceable bush 24. The bushing 24 is seated on an extension 25 of the drive shaft 26, which extends into the interior of the winding core 16. The bushing 24 is resiliently supported with respect to the disk 15 by means of a spiral spring 27.

Beim Aufstecken des zweiten Seitenflansches 13 drückt ein am zweiten Seitenflansch 13 befestigtes federndes Element entsprechend der Pfeilrichtung a auf die Buchse 24, so daß die Einzelsegmente 17 bis 19 gleichzeitig nach außen in die mit unterbrochenen Linien 20 dargestellte Stellung geschwenkt werden.When the second side flange 13 is attached, a resilient element fastened to the second side flange 13 presses on the bushing 24 in the direction of the arrow a, so that the individual segments 17 to 19 are simultaneously pivoted outward into the position shown by broken lines 20.

Bei dem in Figur 2 dargestellten Ausführungsbeispiel besitzt das Einzelsegment 18 eine Aussparung 28, in die der Anfang des Wickelgutes vor dem Wickelvorgang eingeschoben wird. Dabei kann der zweite Seitenflansch 13 entweder noch völlig vom ersten Seitenflansch 5 abgenommen sein oder er ist nur soweit auf den ersten Seitenflansch 5 aufgeschoben, daß die Klemmelemente im Bereich der Aussparung 28 noch nicht wirksam sind. Im letztgenannten Fall können jedoch die Einzelsegmente 17 bis 19 bereits in die Stellung 20 geschwenkt sein. Nachdem der Anfang des Wickelgutes in die Aussparung 28 eingeführt ist, kann dann der zweite Seitenflansch 13 ganz aufgesteckt werden, so daß er unmittelbar am Wickelkern 16 anliegt und diesen seitlich begrenzt.In the exemplary embodiment shown in FIG. 2, the individual segment 18 has a cutout 28 into which the beginning of the material to be wound is inserted before the winding process. The second side flange 13 can either be completely removed from the first side flange 5 or it is only so far on the first sides flange 5 pushed that the clamping elements in the area of the recess 28 are not yet effective. In the latter case, however, the individual segments 17 to 19 can already be pivoted into position 20. After the beginning of the material to be wound is inserted into the recess 28, the second side flange 13 can then be pushed on completely, so that it lies directly against the winding core 16 and laterally delimits it.

Die in Figur 3 dargestellte Draufsicht zeigt den Seitenflansch 5 mit Wickelkem 16, bei dem die Einzelsegmente 17 bis 19 sich in der senkrechten Stellung 20 befinden. Die hier verwendeten Bezugszahlen stimmen in ihrer Bedeutung mit denen von Figur 2 überein. Zum Einfädeln des Wickelgut-Anfanges 29 kann der gesamte Wickelkopf 6 und damit auch der erste Seitenflansch 5 mittels des SchrittMotors 7 in eine definierte Stellung gebracht werden, so daß die Aussparung 28 für den Einfädelvorgang immer in der gleichen Position angeordnet ist. Durch diese Maßnahme kann das Einfädeln des Wickelgut-Anfanges 29 automatisch mittels einer hier nicht dargestellten Einfädelvorrichtung erfolgen.The top view shown in FIG. 3 shows the side flange 5 with a winding core 16, in which the individual segments 17 to 19 are in the vertical position 20. The meaning of the reference numbers used here corresponds to that of FIG. 2. To thread the beginning of the winding material 29, the entire winding head 6 and thus also the first side flange 5 can be brought into a defined position by means of the stepping motor 7, so that the cutout 28 is always arranged in the same position for the threading process. As a result of this measure, the threading of the winding material start 29 can take place automatically by means of a threading device, not shown here.

Die Scheibe 15 des Seitenflansches 5 besitzt symmetrisch angeordnete, radial verlaufende Ausschnitte 30, die es ermöglichen, daß das hier nur andeutungsweise dargestellte aufgewickelte Wickelgut 31 vor dem Entfernen vom Wickelkern 16 abgebunden werden kann.The disc 15 of the side flange 5 has symmetrically arranged, radially extending cutouts 30, which make it possible for the wound winding material 31, which is only indicated here, to be tied off before the winding core 16 is removed.

In Figur 4 ist der Aufbau des zweiten Seitenflansches 13 ersichtlich, der zum Festklemmen des Wickelgut-Anfanges 29 Klemmelemente 32, 33 besitzt. In der Zeichnung sind zwei unterschiedliche Arten von Klemmelementen 32, 33 dargestellt. Das Klemmelement 32 wird von einer Druckfeder 34 in der Pfeilrichtung nach unten gedrückt. Die Kammer 35, in der ein Teil des Klemmelementes 32 und die Druckfeder 34 angeordnet sind, ist vorzugsweise im Querschnitt kreisförmig ausgebildet Das andere Klemmelement 33 ist um eine Achse 36 schwenkbar gelagert und wird mittels einer Zugfeder 37 in der angegebenen Pfeilrichtung bewegt. Die für das Klemmelement 33 vorgesehene. Halterung 38 besitzt einen Anschlag 39, der die Beweglichkeit des Klemmelementes 33 begrenzt.FIG. 4 shows the structure of the second side flange 13, which has 29 clamping elements 32, 33 for clamping the start of the winding material. The drawing shows two different types of clamping elements 32, 33. The clamping element 32 is pressed down by a compression spring 34 in the direction of the arrow. The chamber 35, in which a part of the clamping element 32 and the compression spring 34 are arranged, is preferably circular in cross section. The other clamping element 33 is pivotally mounted about an axis 36 and is moved in the direction of the arrow indicated by means of a tension spring 37. The one provided for the clamping element 33. Bracket 38 has a stop 39 which limits the mobility of the clamping element 33.

Der zweite Seitenflansch 13 besitzt eine Achse 40, die mit einer elektromagnetischen Bremse 14 verbunden ist. Die in den Wickelkern 16 des Wickelkopfes hineinragende Verlängerung 41 der Achse 40 dient ebenfalls als Führungselement für eine federnd angeordnete Buchse 42. Mittels einer verhältnismäßig starken Spiralfeder 43 wird die Buchse 42 gegenüber der als seitliche Begrenzung dienenden Scheibe 44 des zweiten Seitenflansches 13 in der angegebenen Pfeilrichtung weggedrückt. Beim Aufstecken des zweiten Seitenflansches 13 auf den ersten Seitenflansch 5 entsprechend der Pfeilrichtung b, wird zunächst die Buchse 24 von der Buchse 42 in der Pfeilrichtung b nach unten gedrückt, da die Spiralfeder 27 eine geringere Federkraft als die Spiralfeder 43 aufweist. Somit werden die Einzelsegmente 17 bis 19 zunächst in die in Figur 4 dargestellte Stellung gebracht, bevor der zweite Seitenflansch 13 am Wickelkern 16 anliegt. Die Buchse 42 wird erst dann gegen die Federkraft der Spiralfeder 43 nach oben gedrückt, wenn die Buchse 24 ihre untere Endstellung erreicht hat. Die Klemmelemente 32, 33 können so ausgelegt sein, daß sie erst dann wirksam werden, nachdem die Buchse 24 ihre untere Endstellung erreicht hat und der Seitenflansch- 13 weiter bis an den Wickelkern 16 gedrückt wird.The second side flange 13 has an axis 40 which is connected to an electromagnetic brake 14. The extension 41 of the axis 40 protruding into the winding core 16 of the winding head also serves as a guide element for a resiliently arranged bushing 42. By means of a relatively strong spiral spring 43, the bushing 42 is opposite the washer 44 of the second side flange 13 serving as a lateral limitation in the direction of the arrow indicated pushed away. When the second side flange 13 is plugged onto the first side flange 5 in the direction of the arrow b, the bushing 24 is first pressed down by the bushing 42 in the direction of the arrow b, since the coil spring 27 has a lower spring force than the coil spring 43. Thus, the individual segments 17 to 19 are first brought into the position shown in FIG. 4 before the second side flange 13 abuts the winding core 16. The bushing 42 is only pressed upward against the spring force of the spiral spring 43 when the bushing 24 has reached its lower end position. The clamping elements 32, 33 can be designed such that they only become effective after the bush 24 has reached its lower end position and the side flange 13 is pressed further against the winding core 16.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt, welches aber auch dahingehend abgeändert sein kann, daß die Buchse 24 mittels eines speziellen Antriebs völlig unabhängig vom Abnehmen des zweiten Seitenflansches 13 betätigbar ist. Als Antrieb kann hierfür ein pneumatischer Zylinder dienen, der die Buchse 24 in axialer Richtung verschiebt. Dieser pneumatische Antrieb kann auch an der Welle 26 angreifen, die mit der Buchse 24 starr verbunden sein kann. In diesem Fall müßte die Welle 26 axial verschiebbar durch den Seitenflansch 15 hindurchgeführt sein, wobei der Antrieb für den Wickelvorgang an dem in Figur 2 schraffiert dargestellten Flansch angreifen würde. Eine solche Ausführung mit separatem Antrieb für die Buchse 24 hätte den Vorteil, daß das bereits aufgewickelte Wickelgut bei abgenommenem zweiten Seitenflansch 13 noch fest auf dem Wickelkem sitzen würde, wo es vor dem Abwerfen abgebunden werden könnte. Während des Abbindevorgangs wäre dabei sichergestellt, daß das Wickelgut seine Ringform nicht verändert. Erst nach dem erfolgten Abbinden würde dann die Buchse 24 verschoben und damit eine Verjüngung des Wickelkemdurchmessers vorgenommen werden. PatentansprücheIn the drawing, an embodiment is shown, which can also be modified so that the bushing 24 can be actuated by means of a special drive completely independently of the removal of the second side flange 13. A pneumatic cylinder can be used as a drive for this purpose, which displaces the bushing 24 in the axial direction. This pneumatic drive can also engage the shaft 26, which can be rigidly connected to the bushing 24. In this case, the shaft 26 would have to be guided axially displaceably through the side flange 15, the drive for the winding process acting on the flange shown hatched in FIG. 2. Such an embodiment with a separate drive for the bushing 24 would have the advantage that the winding material that had already been wound up would still sit firmly on the winding core when the second side flange 13 was removed, where it could be tied off before being thrown off. During the setting process, it would be ensured that the material to be wound does not change its ring shape. Only after the setting had been carried out would the bushing 24 be displaced and thus the winding core diameter be tapered. Claims
