Description

Die Erfindung betrifft eine Wickeleinrichtung für eine Materialbahn, insbesondere für eine Rollenschneidvorrichtung, nach dem Oberbegriff des Anspruchs 1.The invention relates to a winding device for a Material web, in particular for a roll cutting device, according to the preamble of claim 1.

Eine derartige Wickeleinrichtung ist aus GB 2 162 157 A bekannt. Hier werden die Wickelhülsen von Greifern erfaßt, die an den Haltearmen angeordnet sind, und mit ihnen zur Anlage an einer auf einer Stütztrommel liegenden Materialbahn geschwenkt. Dort können Lagerzapfen in die Wickelhülse eingefahren werden.Such a winding device is from GB 2 162 157 A. known. Here the winding cores are gripped by grippers, which are arranged on the holding arms, and with them to rest on a lying on a support drum Material web pivoted. There can journal be inserted into the winding tube.

Die Erfindung wird im folgenden anhand einer Papierbahn als Beispiel für eine Materialbahn erläutert. Sie ist darauf aber nicht beschränkt.The invention is based on a paper web explained as an example of a material web. she is but not limited to this.

Bevor Papierbahnen zur Auslieferung gelangen, müssen sie auf Rollen aufgewickelt werden. Als Rollenkern wird vielfach eine Wickelhülse verwendet, die beispielsweise aus Pappe besteht. Die fertigen Rollen haben hierbei eine Breite im Bereich von 0,4 bis 3,8 m. Ihr Durchmesser ist vielfach geringer als der von sogenannten Jumborollen, die am Ausgang einer Papiermaschine oder nach der Satinage erzeugt werden. Er liegt im Bereich von 0,3 bis 2,0 m. Before paper webs are delivered, must they are wound on rolls. As a core role often used a winding tube, for example is made of cardboard. The finished roles have here a width in the range of 0.4 to 3.8 m. Your diameter is often less than that of so-called jumbo rolls, that at the exit of a paper machine or after of the satin. It is in the range of 0.3 to 2.0 m.

Die im folgenden als "Fertigrollen" bezeichneten Rollen werden häufig dadurch erzeugt, daß die Papierbahn von der Jumbo- oder Mutterrolle abgewickelt, geschnitten und dann auf den Rollenkern aufgewickelt wird. Hierbei reicht die Bahnlänge einer Jumborolle in der Regel für mehrere Fertigrollen. Beim Übergang von einer Fertigrolle zur nächsten möchte man dabei den Aufwand möglichst klein halten. Dies gilt insbesondere dann, wenn die Wickeleinrichtung Bestandteil einer Rollenschneidvorrichtung ist, weil man dann nach dem Erreichen des gewünschten Durchmessers der Fertigrollen eine Vielzahl von neuen Wickelhülsen zuführen muß.The roles referred to below as "finished roles" are often generated by the paper web of the jumbo or parent roll unwound, cut and then wound up on the roll core. in this connection the web length of a jumbo roll is usually sufficient for several finished rolls. When moving from a finished roll to the next one would like the effort as much as possible keep it small. This applies in particular if the winding device is part of a roll cutting device is because after reaching the desired diameter of the finished rolls a variety of new winding cores.

GB 2 136 403 A beschreibt eine weitere Wickeleinrichtung für einen Rollenschneider, bei dem neue Wickelhülsen in einem Halter abgelegt werden können. Der Halter befindet sich am oberen Ende einer Hubeinrichtung, die ortsfest im Fundament der Wickelvorrichtung angeordnet ist. Mit der Hubeinrichtung kann der Halter angehoben werden, bis die Wickelhülse die Position von Lagerzapfen erreicht.GB 2 136 403 A describes another winding device for a slitter winder with new winding cores can be stored in a holder. The keeper is located at the top of a lifting device, the arranged in the foundation of the winding device is. The holder can be raised with the lifting device until the winding sleeve reaches the position of the journal reached.

DE 23 52 685 A zeigt eine Übergabevorrichtung für einen Rollenwickler, bei dem eine Hülsenaufnahme für neue Wickelhülsen an einem Ende eines Schwenkarms angeordnet ist. Die Hülsenaufnahme weist eine Verriegelungseinrichtung einerseits und einen Umschlingungsgurt andererseits auf. Der Umschlingungsgurt ist um mehrere Rollen geführt und dient dazu, die ersten Lagen der aufzuwickelnden Materialbahn eng an den Spulenumfang anzudrücken.DE 23 52 685 A shows a transfer device for a Roll winder, with a tube holder for new Winding sleeves arranged at one end of a swivel arm is. The sleeve receptacle has a locking device on the one hand and a belt around the other on. The belt is around several roles guided and serves to wind the first layers of the Press the material web tightly against the circumference of the spool.

GB 2 271 345 A zeigt eine Bahnwickelmaschine, bei der die einzelnen Wickelpositionen auf einer umlaufenden Scheibe angeordnet sind. Durch Drehen der Scheibe kann eine volle Wickelrolle in eine Ausgabeposition verdreht werden, wobei gleichzeitig eine neue Wickelhülse in eine Wickelposition bewegt wird. In dieser Wickelposition kann eine haubenförmige Leiteinrichtung um die Wickelhülse gelegt werden, wobei Blasmittel vorgesehen sind, um den Anfang der Materialbahn um die Wickelhülse herum zu blasen.GB 2 271 345 A shows a web winding machine in which the individual winding positions on a rotating Disc are arranged. By turning the disc you can a full winding roll twisted into a dispensing position be, at the same time a new winding tube in a Winding position is moved. In this winding position can a hood-shaped guide device around the winding tube be placed, with blowing agents provided, around the beginning of the material web around the winding tube to blow.

DE 295 13 526 U1 zeigt eine Vorrichtung zum automatischen Hülsenzuführen in Rollenschneidemaschinen des Stützwalzentyps, bei der die Hülsen auf Winkelhebeln abgelegt werden, die angehoben werden können, bis sie die Position von Lagerzapfen erreichen. Hierbei ist eine Verriegelungsvorrichtung vorgesehen, die durch das Eigengewicht der Hülsen gelöst werden kann, so daß nur solche Winkelhebel gekippt werden, die mit einer Wikkelhülse beladen sind.DE 295 13 526 U1 shows an automatic device Sleeve feeding in roll cutting machines of the Back-up roll type, in which the sleeves on angle levers filed, which can be raised until they reach the position of trunnions. Here is one Locking device provided by the Dead weight of the sleeves can be solved, so that only such angle levers are tilted with a winding sleeve are loaded.

BE 691 439 A beschreibt eine Wickelmaschine, bei der Wickelrollen auf zwei Seiten einer zentralen Stützwalze gewickelt werden. Die Wickelrollen werden hierbei durch Haltearme getragen, die sich von der Stützwalze entfernen können, wenn der Durchmesser der Wickelrollen größer wird.BE 691 439 A describes a winding machine in which Winding rolls on two sides of a central support roller be wrapped. The winding rolls are thereby Holding arms worn, which move away from the backup roller can if the diameter of the winding rolls is larger becomes.

Der Erfindung liegt die Aufgabe zugrunde, den Wechsel der Rollen zu erleichtern.The invention has for its object the change to facilitate the roles.

Diese Aufgabe wird gelöst durch eine Wickeleinrichtung mit den Merkmalen des Anspruchs 1.This task is solved by a winding device with the features of claim 1.

Bei einer derartigen Wickeleinrichtung wird die Wickelhülse beim Wickeln auf den Lagerzapfen gehalten. Sie wird freigegeben, indem die Haltearme, an denen die Lagerzapfen befestigt sind, in Axialrichtung der fertigen Rolle auseinandergefahren werden. Alternativ dazu können auch die Lagerzapfen zumindest teilweise in die Tragarme zurückgezogen werden. Beide Bewegungen können auch kombiniert werden. Eine Wickelhülse für eine nachfolgend zu wickelnde Rolle kann auf der Tragschale abgelegt werden. Da die Tragschale an jedem Haltearm zumindest so lange eine größere axiale Erstreckung als die Lagerzapfen aufweist, wie die Lagerzapfen noch nicht in die Wickelhülse eingefahren sind, können die Haltearme in Axialrichtung auseinandergefahren bleiben, ohne daß die Wickelhülse von der Tragschale herunterfällt. Sie kann auf jeden Fall auf dem axial über den Lagerzapfen überstehenden Ende gehalten werden. Gleichzeitig kann sie, wenn die Haltearme die fertige Rolle abgelegt haben, in eine Position verfahren werden, in der sie beim Zusammenfahren der Haltearme oder auch nur der Lagerzapfen von den Lagerzapfen erfaßt werden kann. Mit anderen Worten: die Lagerzapfen können durch eine eigene Bewegung und/oder beim Zusammenfahren der Haltearme in die auf der Tragschale liegenden Wickelhülse eingefahren werden. Damit ist der Übergabevorgang praktisch beendet. Das Auseinanderfahren der Haltearme oder das Zurückziehen der Lagerzapfen zum Abgeben der fertigen Rolle ist ohnehin notwendig. Man nutzt nun den Schritt des Zusammenfahrens aus, um die neue Wickelhülse gleich in der Wickeleinrichtung zu befestigen. Danach kann die Tragschale wieder in die Aufnahmeposition verfahren werden, so daß sie den nachfolgenden eigentlichen Wickelvorgang nicht stört. Mit der Leiteinrichtung für die Materialbahn erfüllt die Tragschale nicht nur die Funktion, die Wickelhülse zu den Lagerzapfen zu transportieren. Sie erleichtert auch das Anlegen des Beginns der zu wickelnden Materialbahn an die Wickelhülse. In diesem Fall verbleibt die Tragschale dann nicht nur so lange im Bereich der Lagerzapfen, bis die Wickelhülse von den Lagerzapfen aufgenommen wird. Sie verbleibt noch einen kurzen Augenblick länger, nämlich bis die Materialbahn zur Anlage an die Wickelhülse gebracht worden ist.In such a winding device, the winding tube held on the trunnion during winding. she is released by the holding arms on which the trunnion are attached in the axial direction of the finished Roll apart to be moved. Alternatively, you can also the bearing pins at least partially in the Support arms are withdrawn. Both movements can can also be combined. A winding tube for a subsequent one Roll to be wrapped can be placed on the tray become. As the carrier shell at least on each arm as long as a larger axial extension than has the bearing journal, like the bearing journal still are not inserted into the winding tube, the Stay arms moved apart in the axial direction, without the winding tube falling off the carrier shell. You can definitely on the axially over the Bearing journal protruding end are kept. simultaneously it can if the holding arms take the finished roll have moved to a position in of them when the holding arms move together or just the bearing journal can be gripped by the bearing journal. In other words: the trunnions can be replaced by a own movement and / or when moving the holding arms together into the winding tube lying on the carrier shell be retracted. The transfer process is therefore practical completed. The spreading of the holding arms or withdrawing the trunnions to deliver the finished one Role is necessary anyway. You now use the Step of moving together to create the new winding tube to fasten in the winding device. After that the tray can be returned to the receiving position be moved so that they follow the actual Winding process does not interfere. With the guidance system for the material web, the carrier shell does not meet only the function of closing the winding tube to the bearing journal transport. It also makes it easier to put on the Beginning of the material web to be wound on the winding tube. In this case, the carrier shell remains not just in the bearing journal area until the Winding sleeve is received by the bearing journal. she remains a little longer, namely until the material web is brought into contact with the winding tube has been.

In einer besonders bevorzugten Ausgestaltung ist vorgesehen, daß die Haltearme von einer Wickelstellung, in der sie im wesentlichen vertikal stehen, in eine Ablagestellung verschwenkbar sind, wobei die Aufnahmeposition der Tragschale dem Schwenkpunkt benachbart ist. Wenn die Haltearme in der Wickelstellung senkrecht stehen, dann sind sie ohne weiteres in der Lage, das mit zunehmenden Wickeldurchmesser größer werdende Gewicht der Rollen zu tragen. Die Ablage der fertigen Rollen erfolgt dann in einer anderen Position, so daß der Abtransport der Rollen den Wickelvorgang einer nachfolgenden Rolle nicht behindert. Da gleichzeitig die Aufnahmeposition der Tragschale dem Schwenkpunkt benachbart ist, kann die Beschickung der Tragschale mit der Wickelhülse der nachfolgenden Rolle relativ frühzeitig erfolgen, d.h. unter Umständen bereits dann, wenn der Haltearm noch in der Ablagestellung liegt. Dies verkürzt die Wechselzeiten.In a particularly preferred embodiment, that the holding arms from a winding position, in which they are essentially vertical, in a storage position are pivotable, the recording position the support shell is adjacent to the pivot point. If the holding arms are vertical in the winding position, then they are easily able to do that with increasing winding diameter increasing weight of the roles to bear. The storage of the finished rolls then takes place in a different position, so that the removal the reels the winding process of a subsequent one Role not hindered. Because at the same time the shooting position the support shell adjacent to the pivot point is, the loading of the tray with the Winding core of the subsequent roll relatively early take place, i.e. under certain circumstances, if the Holding arm is still in the storage position. This shortens the changing times.

Vorzugsweise ist der Schwenkpunkt in Schwerkraftrichtung unterhalb des Lagerzapfens angeordnet. Im Normalbetrieb wirken auf den Haltearm dann ausschließlich Druckkräfte.The pivot point is preferably in the direction of gravity arranged below the journal. In normal operation then only act on the holding arm Compressive forces.

Mit Vorteil weist jeder Haltearm einen Tragschalenantrieb auf, der nur dann aktivierbar ist, wenn sich der Haltearm in der Wickelstellung befindet. Damit wird sichergestellt, daß ein Transport der Wickelhülse in die Wickelstellung nur dann erfolgen kann, wenn der Haltearm tatsächlich in der Lage ist, unmittelbar anschließend den Wickelvorgang zu beginnen. Darüber hinaus hat diese Ausgestaltung den Vorteil, daß die Hülse mit hoher Zuverlässigkeit auf den Tragschalen verbleibt und nicht durch eine Positionsänderung der Tragschale im Raum, wie sie beispielsweise bei einem Verschwenken der Haltearme erfolgen würde, von der Tragschale herabfällt.Each holding arm advantageously has a tray drive which can only be activated if the Holding arm is in the winding position. This ensures that a transport of the winding tube in the Winding position can only take place if the holding arm is actually able to immediately afterwards to start the wrapping process. It also has this configuration has the advantage that the sleeve with high Reliability remains on the trays and not by changing the position of the support shell in the Space, such as when pivoting the Holding arms would take place, falls from the carrier shell.

Mit Vorteil ist die Aufnahmeposition dem unteren Ende einer Schrägfläche benachbart angeordnet. Auf der Schrägfläche können dann die Wickelhülsen der Tragschale zugeführt werden. Die Schrägfläche kann sich insbesondere bei einer Rollenschneidvorrichtung über die gesamte Breite erstrecken, so daß man bei einer Änderung der Breiten der einzelnen Teilbahnen und der damit einhergehenden Änderung der Position und Breiten der Teilbahnrollen immer noch in der Lage ist, die einzelnen Wickelhülsen der Tragschale beziehungsweise dem Paar von Tragschalen zuzuführen.The recording position is advantageously the lower end arranged adjacent to an inclined surface. On the The winding sleeve of the carrier shell can then be inclined are fed. The inclined surface can in particular with a roll cutter over the entire Extend width so that when there is a change the widths of the individual partial webs and the associated ones Change of position and width of the partial web rolls is still able to meet the individual Winding sleeves of the carrier shell or the pair feed from trays.

Hierbei ist besonders bevorzugt, daß die Schrägfläche mit einer Sperrklinke versehen ist. Man kann dann die Übergabe der Wickelhülse von der Schrägfläche an die Tragschale steuern.It is particularly preferred that the inclined surface is provided with a pawl. You can then Transfer of the winding tube from the inclined surface to the Control the tray.

Mit Vorteil ist am oberen Ende der Schrägfläche eine Hülsenzuführeinrichtung angeordnet. Eine derartige Hülsenzuführeinrichtung kann aus einem Magazin bestehen. Sie kann aber auch durch einen Transportwagen gebildet werden, der an das obere Ende der Schrägfläche gefahren werden kann. Von dort kann die Wickelhülse einfach auf die Schrägfläche abgegeben werden.There is an advantage at the upper end of the inclined surface Sleeve feeder arranged. Such a sleeve feeder can consist of a magazine. But it can also be formed by a dolly be driven to the top of the sloping surface can be. From there, the winding tube can simply be opened the inclined surface are given.

Hierbei ist besonders bevorzugt, daß die Leiteinrichtung als Luftleitblech ausgebildet ist. Es reicht hierbei aus, wenn das Luftleitblech auf die Materialbahn im Bereich der Kanten wirkt. Da die Tragschale ohnehin über die axiale Erstreckung der Lagerzapfen vorstehen muß, ergibt sich an den Kanten der Materialbahn ein Streifen, der breit genug ist, um die Führung bewirken zu können. Das Luftleitblech bläst dann den Anfang der Materialbahn sozusagen um den Wickelkern herum, so daß der Wickelvorgang relativ schnell gestartet werden kann.It is particularly preferred that the guide device is designed as an air baffle. It is enough here off when the air baffle on the material web in Area of the edges. Since the carrier shell anyway protrude beyond the axial extension of the trunnion must result at the edges of the material web Strip that is wide enough to effect the lead to be able to. The air baffle then blows the beginning of the Material web, so to speak, around the winding core, so that the winding process can be started relatively quickly can.

Mit Vorteil ist von den beiden Lagerzapfen mindestens einer als Spanndorn ausgebildet und angetrieben. Damit ist die Wickeleinrichtung als Zentrumswickler ausgebildet. Damit die Antriebsleistung auf die Wickelhülse und damit auf die Rolle übertragen werden kann, ist eine zumindest kraftschlüssige Verbindung zwischen dem Lagerzapfen und der Wickelhülse notwendig, die mit relativ wenig Aufwand über einen Spanndorn realisiert werden kann. Der Spanndorn kann beispielsweise pneumatisch betrieben werden.It is an advantage of at least the two journals one designed and driven as a mandrel. In order to the winding device is designed as a center winder. So that the drive power on the winding tube and so that can be transferred to the role is one at least non-positive connection between the bearing journal and the winding tube necessary with the relative little effort can be achieved using a mandrel can. The mandrel can be pneumatic, for example operate.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher beschrieben. Darin zeigen:

The invention is described below with reference to a preferred embodiment in connection with the drawing. In it show:
Fig. 1
is a schematic side view of a winding device and
Fig. 2
a schematic front view of the winding device.

Eine Wickeleinrichtung 1 weist zwei Haltearme 2, 3 auf, die mit Hilfe eines schematisch dargestellten Schwenkantriebs 4 aus einer im wesentlichen senkrechten Stellung, die in Fig. 1 mit durchgezogenen Linien dargestellt ist, in eine Stellung verschwenkt werden kann, in der eine gewickelte Rolle 5 auf dem Fußboden 6 abgelegt werden kann, wie dies in Fig. 1 mit gestrichelten Linien für die Rolle 5 dargestellt ist. Die Rolle bewegt sich dabei mit ihrem Mittelpunkt entlang des Doppelpfeiles 7. Die Haltearme schwenken dabei um Schwenkpunkte 8.A winding device 1 has two holding arms 2, 3, that with the help of a schematically shown swivel drive 4 from an essentially vertical position, which are shown in Fig. 1 with solid lines can be swiveled into a position in which a wound roll 5 placed on the floor 6 can be, as shown with dashed lines in Fig. 1 Lines for the roll 5 is shown. The role moves itself with its center along the double arrow 7. The holding arms swivel about pivot points 8th.

Die Rolle 5 weist eine Wickelhülse 9 als Rollenkern auf. Beim Wickeln wird die Wickelhülse 9 über einen Spanndorn 10 der mit einem Rotationsantrieb 11 verbunden ist, in Drehung versetzt und zieht eine Materialbahn 12 auf sich. Eine Andruckwalze 13 sorgt für einen gesteuerten Aufbau der Rolle.The roll 5 has a winding tube 9 as the roll core on. When winding, the winding tube 9 is a Mandrel 10 connected to a rotary drive 11 is rotated and pulls a material web 12 on himself. A pressure roller 13 ensures one controlled construction of the role.

Die beiden Haltearme 2, 3 sind in Richtung der Doppelpfeile 14, 15 bewegbar. Insbesondere dann, wenn die Wickeleinrichtung 1 in einer Rollenschneidvorrichtung eingesetzt ist, sind die Haltearme 2, 3 dadurch individuell steuerbar. Damit läßt sich nicht nur ihre axiale Position, d.h. die Position in Richtung der Doppelpfeile 14, 15, einstellen, sondern auch der Abstand der Haltearme 2, 3 zueinander, so daß unterschiedlich breite Rollen gewickelt werden können.The two holding arms 2, 3 are in the direction of the double arrows 14, 15 movable. Especially if the Winding device 1 in a roll cutting device is used, the holding arms 2, 3 are thereby individual controllable. This not only allows their axial Position, i.e. the position in the direction of the double arrows 14, 15, but also the distance of the Holding arms 2, 3 to each other, so that different widths Rolls can be wrapped.

Der Haltearm 3 weist einen Lagerzapfen 16 auf, der dem Spanndorn 10 entgegengerichtet ist. Der Spanndorn 10 und der Lagerzapfen 16 können von entgegengesetzten Richtungen in die Wickelhülse 9 eingefahren werden, wenn die Haltearme 2, 3 aufeinander zu bewegt werden. Auch der Lagerzapfen 16 kann als Spanndorn ausgebildet und angetrieben sein.The holding arm 3 has a bearing pin 16 which the Mandrel 10 is opposite. The mandrel 10 and the journal 16 can be of opposite Directions are inserted into the winding tube 9, if the holding arms 2, 3 are moved towards each other. The bearing pin 16 can also be designed as a mandrel and be driven.

Am Haltearm 2 ist eine Tragschale 17 und am Haltearm 3 eine Tragschale 18 angeordnet. Die beiden Tragschalen 17, 18 können aus einer unteren Position, die gestrichelt eingezeichnet ist, in eine obere Position, die mit durchgezogenen Linien eingezeichnet ist, bewegt werden. Hierfür weisen sie einen nicht näher dargestellten Antrieb auf. Dieser Antrieb kann beispielsweise durch ein Spindelsystem gebildet werden.There is a support shell 17 on the holding arm 2 and 3 on the holding arm a carrier shell 18 is arranged. The two trays 17, 18 can be from a lower position, which is dashed is drawn in an upper position, the is drawn with solid lines become. For this they have a not shown Drive on. This drive can, for example be formed by a spindle system.

Die untere Position, die in der Nähe des Schwenkpunkts 8 angeordnet ist (siehe Fig. 1), dient als Aufnahmeposition. In dieser Position kann eine Wickelhülse von einer Schrägfläche 19, wo sie mit Hilfe einer Sperrklinke 20 festgehalten wird, in die Tragschalen 17, 18 rollen. In Fig. 1 sind mehrere Wickelhülsen in verschiedenen Positionen dargestellt. Eine weitere Wickelhülse befindet sich auf einem Transportschlitten 21 am oberen Ende der Schrägfläche 19, der zur Zufuhr der Wickelhülsen dient.The lower position, which is near the pivot point 8 is arranged (see Fig. 1), serves as the receiving position. In this position, a winding tube from an inclined surface 19, where it with the help of a pawl 20 is held in the support shells 17, 18th roll. In Fig. 1 there are several winding tubes in different Positions shown. Another winding tube is located on a carriage 21 on upper end of the inclined surface 19, which is used to supply the Serves winding sleeves.

Die Tragschalen 17, 18 haben eine größere axiale Erstreckung als der Spannbolzen 10 und der Lagerzapfen 16, d.h. sie ragen über den Spannbolzen 10 bzw. den Lagerzapfen 16 in Axialrichtung hinaus. Damit ist es möglich, daß die Wickelhülse 9 zwar auf den Tragschalen 17, 18 aufliegt und von diesen aus der Aufnahmeposition in die Übergabeposition (obere Position) bewegt werden kann, ohne von dem Spannbolzen 10 und dem Lagerzapfen 16 behindert zu werden. Wenn die Tragschalen 17, 18 ihre Übergabeposition erreicht haben, dann können die beiden Haltearme 2, 3 aufeinander zu bewegt werden. Hierbei werden der Spannbolzen 10 und der Lagerzapfen 16 in die Wickelhülse 1 gefahren. Die Wickelhülse 9 gleitet dabei auf den Tragschalen 17, 18, was ohne Probleme möglich ist. Wenn die Wickelhülse 9 zwischen den beiden Haltearmen 2, 3 auf dem Spanndorn 10 und dem Lagerzapfen 16 eingespannt ist, können sich die Tragschalen 17, 18 wieder nach unten bewegen.The support shells 17, 18 have a larger axial extent than the clamping bolt 10 and the bearing pin 16, i.e. they protrude over the clamping bolt 10 or the bearing journal 16 in the axial direction. It is possible that the winding tube 9 is indeed on the trays 17, 18 rests and from the receiving position be moved to the transfer position (upper position) can without the clamping bolt 10 and the bearing pin 16 to be hindered. If the support shells 17, 18 their Have reached the transfer position, then the two holding arms 2, 3 are moved towards each other. Here, the clamping bolt 10 and the bearing pin 16 moved into the winding tube 1. The winding tube 9 slides on the trays 17, 18, what without Problems is possible. If the winding tube 9 between the two holding arms 2, 3 on the mandrel 10 and the Bearing pin 16 is clamped, the support shells 17, 18 move down again.

In Fig. 1 ist dargestellt, daß sich die Tragschalen auf der Zuführseite der Materialbahn 12 verlängern. Sie bilden dort ein Luftleitblech 22, welches es erleichtert, die Materialbahn 12 um die Wickelhülse herumzuleiten, so daß der Wickelvorgang fast automatisch begonnen werden kann.In Fig. 1 it is shown that the support shells on extend the feed side of the material web 12. she form an air baffle 22 there, which facilitates to guide the material web 12 around the winding tube, so that the wrapping process started almost automatically can be.

Wenn die Tragschalen 17, 18 derartige Luftleitbleche 22 aufweisen, dann bleiben die Tragschalen 17, 18 in der Übergabeposition (obere Position), bis der Wickelvorgang begonnen hat. Danach werden sie abgesenkt. Hierbei können die Luftleitbleche 22 gegebenenfalls weggeklappt werden, damit sie nicht an der Wickelhülse hängen bleiben. Wenn die Luftleitbleche 22 fehlen, können die Tragschalen 17, 18 bereits dann abgesenkt werden, wenn die Wickelhülse 9 zwischen dem Spanndorn 10 und dem Lagerzapfen 16 aufgehängt ist.If the support shells 17, 18 such air baffles 22nd have, then the support shells 17, 18 in the Transfer position (upper position) until the winding process has begun. Then they are lowered. in this connection the air baffles 22 can be folded away if necessary so that they do not get caught on the winding tube. If the air baffles 22 are missing, the Carrier shells 17, 18 are already lowered when the winding sleeve 9 between the mandrel 10 and the bearing journal 16 is suspended.

Der Antrieb der Tragschalen 17, 18 kann so ausgebildet sein, daß die Tragschalen 17, 18 nur dann von ihrer Aufnahmeposition in die Übergabeposition bewegt werden können, wenn die Haltearme 2, 3 sich in ihrer Wickelstellung befinden, also senkrecht stehen. In dieser Lage ist nämlich sichergestellt, daß die Tragschalen nach unten geschlossen und praktisch nur nach oben offen sind, so daß die Wickelhülse 9 nicht herausfallen kann.The drive of the support shells 17, 18 can be designed in this way be that the support shells 17, 18 only from their Recording position can be moved to the transfer position can when the holding arms 2, 3 are in their winding position located, i.e. standing vertically. In this situation it is ensured that the trays after closed at the bottom and practically only open at the top are so that the winding tube 9 cannot fall out.

Der Übergang auf eine neue Rolle geht bei der dargestellten Wickeleinrichtung relativ schnell. Sobald eine Rolle 5 fertig gewickelt ist, schwenken die Haltearme 2 und legen die Rolle auf dem Fußboden 6 ab. Sobald die Rolle dort unterstützt ist, fahren die beiden Haltearme 2, 3 auseinander und geben die Rolle frei. Im auseinandergefahrenen Zustand werden die Haltearme 2, 3 wieder in ihre vertikale Position zurückgeschwenkt. Die Tragschalen 17, 18 befinden sich in ihrer Aufnahmeposition. Eine neue Wickelhülse 9 rollt auf die Tragschalen und wird dann von ihnen nach oben zu der Übergabeposition verbracht. Sobald die Wickelhülse dort angelangt ist, fahren die beiden Haltearme 2, 3 zusammen, und der Wikkelvorgang kann beginnen.The transition to a new role goes with the one shown Winding device relatively quickly. As soon as one Roll 5 is completely wound, pivot the holding arms 2 and put the roll on the floor 6. As soon as the Role is supported there, the two holding arms move 2, 3 apart and release the role. I'm apart Condition will be the arms 2, 3 again pivoted back into its vertical position. The support shells 17, 18 are in their receiving position. A new winding tube 9 rolls on the trays and will then move up from them to the transfer position spent. As soon as the winding tube has got there, the two holding arms 2, 3 move together, and the winding process can start.
