Description

Die Erfindung betrifft eine Vorrichtung zum Aufwickeln von Materialbahnen, insbesondere Papier- und Textilbahnen, die der Aufwickelvorrichtung mittels einer Vorschubeinrichtung diskontinuierlich zugeführt werden, wobei die Vorschubeinrichtung und eine Aufwickelwelle der Aufwickelvorrichtung durch einen Riemenantrieb gekoppelt sind.The invention relates to a device for winding material webs, in particular paper and textile webs, which are fed to the winding device discontinuously by means of a feed device, the feed device and a winding shaft of the winding device being coupled by a belt drive.

Bei einer derartigen Vorrichtung ist es nicht möglich, die Vorschubeinrichtung und die Aufwickelvorrichtung synchron diskontinuierlich anzutreiben, da mit zunehmendem Wickeldurchmesser auch die Länge des pro Antriebsschritt aufgewickelten Materialbahnabschnittes zunimmt.With such a device, it is not possible to drive the feed device and the winding device synchronously discontinuously, since the length of the material web section wound per drive step also increases with increasing winding diameter.

Es sind Aufwickelvorrichtungen bekannt, welche die Aufwickelwelle mit einem kontinuierlich wirkenden Drehmoment antreiben. Wenn die Materialbahn vor dem Aufwickeln eine Bearbeitungsstation durchläuft, in der eine Bearbeitung der stillstehenden Materialbahn erfolgt, so muß das an der Aufwickelwelle angreifende Drehmoment begrenzt werden, damit die Materialbahn nicht während des Bearbeitungsvorganges aus der Bearbeitungsstation herausgezogen wird. Dadurch ist die erreichbare Festigkeit des Wickels beschränkt, so daß dieser viel Raum benötigt.Winding devices are known which drive the winding shaft with a continuously acting torque. If the material web passes through a processing station in which processing of the stationary material web takes place, the torque acting on the winding shaft must be limited so that the material web is not pulled out of the processing station during the processing operation. This is the achievable strength of the winding is limited, so that it requires a lot of space.

Ferner sind Aufwickelvorrichtungen bekannt mit einem Antrieb, der über eine Meldung, z. B. einen eine Vorratsbildung von Wickelgut vor der Aufwickelvorrichtung feststellenden Kontakt gesteuert wird. Diese Aufwickelvorrichtungen besitzen ebenfalls den oben genannten Nachteil einer lockeren Wickelbildung.Furthermore, take-up devices are known with a drive, which via a message, for. B. a supply of winding material is controlled in front of the winding device determining contact. These winding devices also have the above-mentioned disadvantage of loose winding.

Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute Vorrichtung der eingangs genannten Art anzugeben, welche die Bildung eines festen Wickels ermöglicht, ohne daß die Gefahr besteht, daß die Materialbahn während des Bearbeitungsvorganges aus der Bearbeitungsstation herausgezogen wird.The invention has for its object to provide a simply constructed device of the type mentioned, which enables the formation of a fixed roll without the risk that the material web is pulled out of the processing station during the processing operation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Riemen des Riemenantriebs in seiner Längsrichtung elastisch dehnbar ist und daß die Aufwickelwelle mit dem einen Teil eines Rastgesperres verbunden ist, dessen anderes Teil durch eine mit der Vorschubeinrichtung verbundene Mitnehmeranordnung intermittierend in seine Freigabestellung bewegbar ist.This object is achieved in that the belt of the belt drive is elastically stretchable in its longitudinal direction and that the winding shaft is connected to one part of a locking mechanism, the other part of which can be moved intermittently into its release position by a driver arrangement connected to the feed device.

Bei der erfindungsgemäßen Aufwickelvorrichtung wird bei einem oder mehreren Vorschubschritten der Vorschubeinrichtung der elastische Riemen elastisch gedehnt und damit gespannt, so daß bei der Freigabe des Rastgesperres die Aufwickelwelle durch den sich entspannenden elastischen Riemen ruckartig verdreht wird und dabei die Materialbahn aufwickelt. Durch das ruckartige Verdrehen der Aufwickelwalze wird die aufzuwickelnde Materialbahn gespannt so daß sich ein fester Wickel bildet. Die von der Vorschubeinrichtung über den Riemenantrieb auf die Aufwickelwelle übertragene Antriebsenergie wird daher zunächst in dem elastischen Riemen gespeichert, bevor sie beim Lösen des Rastgesperres schlagartig auf die Aufwickelwelle übertragen wird.In the take-up device according to the invention, the elastic belt is elastically stretched and thus tensioned in one or more feed steps of the feed device, so that when the locking mechanism is released, the take-up shaft is jerked by the relaxing elastic belt and thereby winds up the material web. The jerky twisting of the take-up roller turns the take-up roller Material web stretched so that a firm wrap is formed. The drive energy transmitted from the feed device via the belt drive to the winding shaft is therefore first stored in the elastic belt before it is suddenly transmitted to the winding shaft when the locking mechanism is released.

Gemäß einer bevorzugten Ausführungsform ist die Aufwickelwelle mit einem Rastrad mit an seinem Umfang ausgebildeten Rastzähnen drehfest verbunc2n, zwischen die ein zwischen einer L.ngriffsstellung und einer Freigabestellung verschwenkbar gelagerter Rasthebel eingreift, wobei der Rasthebel über eine Klinke verschwenkbar ist, die im Wege der Mitnehmerzähne eines mit der Antriebswelle der Vorschubeinrichtung drehfest verbundenen Mitnehmerrades angeordnet ist.According to a preferred embodiment, the winding shaft is provided with a ratchet wheel having formed on its periphery ratchet teeth rotationally fixed verbunc 2n, between which engages a pivotally mounted between a L.ngriffsstellung and a release position detent lever, the detent lever via a jack is pivoted, the way of driving teeth a driving wheel connected to the drive shaft of the feed device in a rotationally fixed manner is arranged.

Die Papieraufwickelvorrichtung ist in Verbindung mit einem Schreib- oder Druckwerk dargestellt. Die Figuren zeigen jeweils eine, nämlich die rechte Lagerplatine 1 des Schreibwerkes, an der alle für die Funktion erforderlichen Bauteile gelagert sind.The paper winder is shown in connection with a writing or printing unit. The figures each show one, namely the right-hand mounting plate 1 of the writing mechanism, on which all the components required for the function are mounted.

Von einer Papiervorratsrolle 2 wird eine Papierbahn 3 um eine Führungsstange 29 und weiter um eine Schreibwalze 6 des Schreibwerkes zu einem Wickeldorn oder einer Aufwickelwelle 4 geführt, wo das Vorderende der Papierbahn in einem Klemmschlitz 5 gehalten wird. Nahe der Führungsstange 29 ist eine Spannachse 30 angeordnet, die beidendig an Andruckhebeln 31 befestigt ist, die ihrerseits im Nieten 33 schwenkbar an der Lagerplatine 1 gelagert und mit Hilfe von Federn 32 so vorgespannt sind, daß die Spannachse 30 gegen die Papierbahn 3 gedrückt wird und die Papierbahn vor dem Einlauf in die Bearbeitungsstation (die Schreibwalze) straff hält. Mit Hilfe von Andruckrollen 7 und 71 wird die Papierbahn gegen die Schreibwalze gedrückt, um eine gute Übertragung der Abzugskraft von der Schreibwalze 6 auf die Papierbahn 3 zu erreichen.From a paper supply roll 2, a paper web 3 is guided around a guide rod 29 and further around a platen roller 6 of the writing mechanism to a winding mandrel or a winding shaft 4, where the front end of the paper web is held in a clamping slot 5. Near the guide rod 29 there is a tensioning axis 30, which is attached at both ends to pressure levers 31, which in turn are pivotally mounted in the rivets 33 on the bearing plate 1 and are preloaded with the aid of springs 32 so that the tensioning axis 30 is pressed against the paper web 3 and the paper web taut before entering the processing station (the platen). With the help of pressure rollers 7 and 71, the paper web is pressed against the platen roller in order to achieve a good transfer of the pulling force from the platen roller 6 to the paper web 3.

In der Fig. 2 erkennt man den Antrieb der Schreibwalze 6. Ein Motor 16 treibt über ein Getriebe 17, ein Ritzel 18 und ein Zwischenrad 19 ein Zahnrad 20 an, das drehfest mit der Welle 8 der Schreibwalze 6 verbunden ist. Mit der Welle 8 ist ferner eine Keilriemenscheibe 21 verbunden, von der über einen elastischen Vierkant-Keilriemen 22 eine Keilriemenscheibe 26 und eine mit dieser drehfest verbundene Achse 25 des Wickelantriebes angetrieben wird (siehe auch Fig. 3 bis 5). Die Achse 25 ist-in einem-Haltewinkel 28 und in einem Federgehäuse 23 axial verschiebbar gelagert, um den Wickeldorn 4 von der Achse 25 abkuppeln und den Wickel aus dem Schreibwerk herausnehmen zu können. Zum Auskuppeln ist eine Verschiebeinrichtung vorgesehen, die einen an der Lagerplatine 1 befestigten gezahnten Stator 27 und einen auf der Achse 25 drehbar gelagerten gezahnten Ausheber 24 mit einem Betätigungshebel 241 umfaßt. Die Fig. 4 zeigt den Ausheber 24 in Eingriff mit dem Stator 27 entsprechend der Kupplungsstellung zwischen Achse 25 und Wickeldorn 4. In dieser Stellung wird die Achse 25 durch eine in dem Federgehäuse 23 untergebrachte Feder mit dem Wickeldorn 4 in einer Drehmoment übertragenden Verbindung gehalten. Fig. 5 zeigt dagegen den Ausheber 24 in seiner ausgehobenen Stellung, in der die Zähne von Ausheber 24 und Stator 27 durch ein Verdrehen des Aushebers übereinander stehen. Dadurch wird die Achse 25 in axialer Richtung entgegen der Vorspannung der in dem Federgehäuse 23 untergebrachten Feder nach rechts (in den Fig. 4 und 5 betrachtet) verschoben und die Drehmoment übertragende Verbindung zwischen der Achse 25 und dem Wickeldorn 4 gelöst, so daß der Wickel aus dem Schreibwerk entnommen werden kann.The drive of the platen roller 6 can be seen in FIG. 2. A motor 16 drives a gearwheel 20 via a gear 17, a pinion 18 and an idler gear 19, which gear rotates is connected to the shaft 8 of the platen roller 6. Also connected to the shaft 8 is a V-belt pulley 21, from which a V-belt pulley 26 and an axis 25 of the winding drive, which is connected in a rotationally fixed manner, is driven via an elastic square V-belt 22 (see also FIGS. 3 to 5). The axis 25 is mounted axially displaceably in a holding bracket 28 and in a spring housing 23 in order to uncouple the winding mandrel 4 from the axis 25 and to be able to remove the winding from the writing mechanism. For disengaging, a displacement device is provided which comprises a toothed stator 27 fastened to the bearing plate 1 and a toothed lifter 24 rotatably mounted on the axis 25 with an actuating lever 241. 4 shows the lifter 24 in engagement with the stator 27 in accordance with the coupling position between the axis 25 and the winding mandrel 4. In this position, the axis 25 is held in a torque-transmitting connection with the winding mandrel 4 by a spring accommodated in the spring housing 23. 5, on the other hand, shows the lifter 24 in its raised position, in which the teeth of the lifter 24 and the stator 27 are positioned one above the other by rotating the lifter. As a result, the axis 25 is displaced in the axial direction against the bias of the spring accommodated in the spring housing 23 to the right (viewed in FIGS. 4 and 5) and the torque-transmitting connection between the axis 25 and the winding mandrel 4 is released, so that the winding can be taken from the writing mechanism.

Die Achse 25 ist ferner mit einem Rastrad 15 mit Rastzähnen 151 drehfest verbunden, in die ein Rasthebel 13 mit einer Rastklinke 14 eingreift. Der Rasthebel 13 ist mittels einer Buchse 101 auf einem Stift 11 drehbar gelagert (Fig. 1) der seinerseits an der Lagerplatine 1 befestigt ist. Eine einerseits an der Lagerplatine und andererseits an dem Rasthebel 13 angreifende Feder 12 spannt den Rasthebel 13 in seine Raststellung vor. Der Rasthebel 13 weist an seinem der Rastklinke 14 abgewandten Ende einen Klinkenhebel 10 auf, der zum Eingriff in ein Mitnehmerrad 9 bestimmt ist, das auf der Achse 8 der srhreibwalze 6 befestigt ist. Das Mitnehmerrad 9 weist auf seinem Umfang Mitnehmerzähne 91 auf, deren gegenseitiger Abstand etwa jeweils zwei Schreibzeilen entspricht.The axis 25 is also non-rotatably connected to a ratchet wheel 15 with ratchet teeth 151 into which a ratchet lever 13 engages with a latch 14. The locking lever 13 is rotatably mounted on a pin 11 by means of a bushing 101 (FIG. 1), which in turn is fastened to the bearing plate 1. A spring 12 acting on the one hand on the bearing plate and on the other hand on the latching lever 13 biases the latching lever 13 into its latching position. The latching lever 13 has at its end facing away from the latching pawl 14 a latching lever 10 which is intended for engagement in a driving wheel 9 which is fastened on the axis 8 of the friction roller 6. The driving wheel 9 has driving teeth 91 on its circumference, the mutual spacing of which corresponds to approximately two writing lines each.

Sobald eine Zeilenschaltung der Schreibwalze 6 erfolgt, bildet die Papierbahn 3 hinter derselben eine kleine Vorratsschlaufe, während sich der Keilriemen 22 spannt, da die Rastklinke 14 ein Verdrehen der Achse 25 und damit des Wickeldornes 4 verhindert. Nach einer oder zwei weiteren Zeilenschaltungen hat dann der gerade mit dem Klinkenhebel 10 in Eingriff stehende Mitnehmerzahn 91 den Klinkenhebel 10 und damit den Rasthebel 13 soweit verschwenkt, daß die Rastklinke 14 aus den Rastzähnen 151 ausgehoben ist und der Keilriemen 22 über die Achse 24 ruckartig den Wickeldorn 4 und damit den Wickel antreibt. Danach rastet der Rasthebel 13 wieder ein. Die ruckartige Wickelbewegung führt zu einer festen Wickelbildung. Andererseits bewirkt sie kein Herausziehen des Papiers aus der Schreibstellung auf der Schreibwalze, da die Papierbahn durch die Führung um die Führungsstange 29 einen großen Wickelbereich der Schreibwalze 6 umschlingt. Ein ständiger Zug auf die Papierbahn von der Aufwickelvorrichtung her erfolgt nicht, da das Rastgesperre den Riemenzug aufnimmt.As soon as a line connection of the platen roller 6 takes place, the paper web 3 forms a small supply loop behind it, while the V-belt 22 tightens, since the latching pawl 14 prevents the axis 25 and thus the winding mandrel 4 from rotating. After one or two further line connections, the driver tooth 91 which is currently engaged with the ratchet lever 10 has pivoted the ratchet lever 10 and thus the latching lever 13 to such an extent that the latching pawl 14 is lifted out of the latching teeth 151 and the V-belt 22 abruptly over the axis 24 Winding mandrel 4 and thus drives the winding. Then the locking lever 13 engages again. The jerky winding movement leads to a firm winding. On the other hand, it does not pull the paper out of the writing position on the platen roller, since the paper web wraps around a large winding area of the platen roller 6 through the guide around the guide rod 29. There is a constant pull on the paper web from the take-up device not because the locking mechanism picks up the belt pull.

Der elastische Vierkant-Keilriemen gewährleistet ein ausreichendes Drehmoment sowie eine ausreichende Speicherung der Vorschubenergie und gleicht durch Gleiten auf der Riemenscheibe 26 das sich ständig ändernde Übersetzungsverhältnis bei zunehmender Wickeldicke aus.The elastic square V-belt ensures sufficient torque and sufficient storage of the feed energy and, by sliding on the pulley 26, compensates for the constantly changing transmission ratio with increasing winding thickness.

Die Elastizität des Keilriemens 22 muß so gewählt werden, daß die in dem Keilriemen 22 während der Sperrung des Wickeldornes 4 vom Antrieb her eingespeicherte Energie ausreicht, die Reibungsverluste zu überwinden, die bei einem vollen Wickel in den Lagern des Wickeldornes 4 und den Lagern der Achse 25 auftreten. Ein nach dem erfolgten Drehen des Wickeldornes verbleibender Energieüberschuß wird durch die erneute Verrastung des Rastgesperres 13, 14, 15 aufgefangen und wirkt nur sehr kurz bis zur Verrastung auf die Papierbahn 3 zurück, so daß kein Nachziehen der Papierbahn 3 aus der Bearbeitungsstellung 61 erfolgen kann.The elasticity of the V-belt 22 must be chosen so that the energy stored in the V-belt 22 during the locking of the winding mandrel 4 from the drive is sufficient to overcome the frictional losses that occur with a full winding in the bearings of the mandrel 4 and the bearings of the axle 25 occur. Any excess energy remaining after the winding mandrel has been rotated is caught by the renewed latching of the locking mechanism 13, 14, 15 and acts only very briefly until it latches back onto the paper web 3, so that no retraction of the paper web 3 from the processing position 61 can take place.

Die in dem Riemen elastisch speicherbare Energie ergibt sich einerseits aus dem Reibschluß zwischen dem Keilriemen 22 und der Riemenscheibe 26 und andererseits aus der Dehnung des Keilriemens 22 auf der Zugseite zwischen den Riemenscheiben 26 und 21 bei diesem Reibschluß.The energy which can be stored elastically in the belt results on the one hand from the frictional engagement between the V-belt 22 and the pulley 26 and on the other hand from the expansion of the V-belt 22 on the pulling side between the pulleys 26 and 21 in this frictional engagement.

Ein wesentlicher Vorteil der erfindungsgemäßen Vorrichtung liegt darin, daß die Belastung des Antriebes durch die Wickelvorrichtung nicht von der veränderlichen Größe des Wickels abhängt, sondern nur von dem zum Spannen des Keilriemens 22 über die Riemenscheibe 21 erforderlichen Drehmoment.A major advantage of the device according to the invention is that the load on the drive by the winding device does not depend on the variable size of the winding, but only on the torque required to tension the V-belt 22 via the pulley 21.
