Description

Die Erfindung betrifft eine Wickelmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a winding machine according to the preamble of claim 1.

Eine solche Wickelmaschine ist aus DE 31 09 587 C2 bekannt geworden. Dabei geht es darum, Maßnahmen zu treffen, um beim Durchtrennen der Bahn ein Beschädigen der Antriebsfläche der bahnumschlungenen Walze durch die Klinge zu vermeiden. Zu diesem Zwecke ist dem Klingenträger ein Halteorgan zugeordnet, das sich auf der Papierbahn und damit auf der Mantelfläche der bahnumschlungenen Walze im Augenblick des Schneidens abstützen kann, so daß ein gewisser Mindestabstand zwischen der Schneide der Klinge und der Mantelfläche der Walze bestehen bleibt.Such a winding machine has become known from DE 31 09 587 C2. The aim is to take measures to prevent the blade from damaging the drive surface of the roll wrapped in the web when the web is cut. For this purpose, the blade carrier is assigned a holding member which can be supported on the paper web and thus on the outer surface of the roll wrapped in the web at the moment of cutting, so that a certain minimum distance between the cutting edge of the blade and the outer surface of the roller remains.

Eine ähnliche Vorrichtung ist aus DE-AS 29 30 474 bekannt geworden. Dabei arbeitet das Halteorgan mit einer mit Ausnehmungen versehenen schmalen Kante mit einer mit entsprechenden Ausnehmungen versehenen Perforierklinge zusammen, die im wesentlichen in Umfangsrichtung der Tragwalze im Abstand von deren Oberfläche auf das Halteorgan zubewegt wird. Dabei sind sowohl für das Halteorgan als auch die Perforierklinge je eine gesonderte Halterung und je ein gesonderter Schwenkantrieb nötig.A similar device is known from DE-AS 29 30 474. The holding member cooperates with a narrow edge provided with recesses with a perforating blade provided with corresponding recesses, which is moved towards the holding member essentially in the circumferential direction of the support roller at a distance from its surface. A separate holder and a separate swivel drive are required for both the holding member and the perforating blade.

Weiterhin wird auf DE-OS 29 20 707 verwiesen. Hierbei kommt es zu einem Andrücken der Schneide der Klinge an die Mantelfläche der betreffenden Tragwalze, so daß diese beschädigt werden kann.Furthermore, reference is made to DE-OS 29 20 707. This results in the cutting edge of the blade being pressed against the lateral surface of the supporting roller in question, so that it can be damaged.

Bei Wickelmaschinen gemäß dem Gattungsbegriff ist ein weiteres Problem aufgetreten, das besonders unangenehm bei schweren, steifen Papiersorten in Erscheinung tritt. Wird nämlich die fertige Wickelrolle aus dem Wickelbett ausgestoßen, so daß die zu durchtrennende Bahn unter Spannung an der Schneide der Klinge anliegt, so wird hierdurch eine Kraft auf die Klinge ausgeübt, und damit auf den Klingenträger sowie auf die gesamte Bahn-Trenneinrichtung. Die Bahn-Trenneinrichtung besteht im allgemeinen aus einer maschinenbreiten Platte, die an beiden Enden gelagert ist. Diese Platte und gegebenenfalls der Klingenträger werden aufgrund der genannten Krafteinwirkung verbogen. Ist die Klinge nicht mehr besonders scharf, so kann dies dazu führen, daß durch die Verbiegung eine Durchtrennung der Bahn überhaupt unterbleibt.Another problem has arisen in winding machines according to the generic term, which is particularly unpleasant with heavy, stiff types of paper. If the finished winding roll is ejected from the winding bed, so that the web to be cut rests under tension on the cutting edge of the blade, this exerts a force on the blade, and thus on the blade carrier and on the entire web cutting device. The web separator generally consists of a machine-wide plate that is supported at both ends. This plate and possibly the blade carrier are bent due to the aforementioned force. If the blade is no longer particularly sharp, this can result in the bend not cutting through the web at all.

Als Abhilfe könnte daran gedacht werden, die Trenneinrichtung insgesamt steifer zu machen, vor allen Dingen die genannte Platte. Dem sind jedoch Grenzen gesetzt, da der Zwischenraum zwischen den beiden Tragwalzen nur minimal ist. Selbst wenn man die Platte steifer macht, so daß diese der Kraft standhält, ohne sich zu verbiegen, hat die Kraft dennoch nachteilige Folgen für das Gelenk, über welches der Klingenträger an der Platte gelagert wird. Dieses kann nämlich ebenfalls nicht beliebig stark dimensioniert werden.As a remedy, one could think of making the separating device more rigid overall, above all the plate mentioned. There are limits to this, however, since the space between the two support rollers is minimal. Even if the plate is made stiffer so that it can withstand the force without bending, the force still has adverse consequences for the joint via which the blade carrier is mounted on the plate. This is because it cannot be dimensioned to any size.

Der Erfindung liegt die Aufgabe zugrunde, eine Wickelmaschine gemäß dem Oberbegriff von Anspruch 1 derart zu gestalten, daß bei steifen, schweren Papiersorten eine Verbiegung der Trenneinrichtung bzw. ihrer Teile unterbunden bleibt, und daß auch keine unzulässig hohen Kräfte auf das Gelenk zwischen Klingenträger und Platte einwirken; auf jeden Fall soll sichergestellt werden, daß die Bahn einwandfrei vertrennt wird.The invention has for its object to design a winding machine according to the preamble of claim 1 such that in the case of stiff, heavy types of paper a bending of the separating device or its parts is prevented, and that no impermissibly high forces act on the joint between the blade support and the plate; in any case, it should be ensured that the web is properly separated.

Diese Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is solved by the characterizing features of claim 1.

Die Erfindung ist anhand eines Ausführungsbeispieles mit Bezug auf die Zeichnung näher erläutert. Darin zeigt

Fig. 1 und 2
schematisch in Seitenansicht eine Doppeltragwalzenwickelmaschine mit einer Trennvorrichtung nach der Erfindung in zwei verschiedenen Betriebsstellungen und

The invention is explained in more detail using an exemplary embodiment with reference to the drawing. It shows
1 and 2
schematically in side view a double carrier roll winding machine with a separating device according to the invention in two different operating positions and
Fig. 3
increases the area of the separating device when separating the web.

Die Fig. 1 zeigt einen auf zwei Tragwalzen 3 und 4 einer Tragwalzenwickelmaschine ruhenden fertig gewickelten Wickel 5. Die ankommende Warenbahn 6, welche die Tragwalze 3 teilweise umschlingt, ist noch nicht von dem fertigen Wickel 5 abgetrennt. Zwischen beiden Tragwalzen 3 und 4 ist bereits eine Trennvorrichtung in den zwischen den Tragwalzen 3 und 4 und dem Wickel 5 gebildeten Zwickel hochgebracht worden. Die Trennvorrichtung besteht aus einem beidseitig geführten Balken 7, der an seinem oberen Ende einen schwenkbar angeordneten Klingenträger 8 aufweist, an dem eine Abreißklinge 9 angeschraubt ist. In dem Klingenträger 8 sind im Abstand von der Abreißklinge 9 als Bolzen ausgebildete Halteorgane 10 verteilt über die Klingenbreite eingeschraubt. Die Halteorgane 10 tragen auf ihren der Tragwalze 3 zuweisenden Enden Filzauflagen 11. Der Klingenträger 8 kann mittels seitlicher Gestänge 12, die an fest an dem Träger angebrachten Hebeln 13 angreifen, gegen die Tragwalzen 3 geschwenkt werden (Fig. 2 und 3). In dieser Betriebsstellung klemmen die Halteorgane 10 die Warenbahn 6 fest gegen die Tragwalze 3, während zwischen der Abreißkante der Klinge 9 und der Warenbahn 6 ein geringer Spalt s verbleibt. Erst wenn der Wickel 5 durch die Ausdrückrolle 14 über die zweite Tragwalze 4 bewegt wird, kommt die Warenbahn 6 zum Anliegen an die Abreißkante der Abreißklinge 9, die in an sich bekannter Weise als Perforierkante gezahnt ausgebildet sein kann. Die Warenbahn 6 reißt von dem fertigen Wickel 5 ab und letzterer kann weiterbefördert werden. Nunmehr wird innerhalb der Tragwalze 3 ein Vakuum aufgebracht, welches durch Bohrungen 15 im Tragwalzenmantel die abgetrennte Warenbahn festhält, so daß die Abreißklinge 9 von der Warenbahn abgeschwenkt und die gesamte Trennvorrichtung wieder abgesenkt werden kann, um Platz für einen in den Zwickel einzulegenden neuen Wickelkern zu schaffen, der dann die ankommende Warenbahn gegen die Tragwalze 3 hält. Beim Wickelbeginn wird die Warenbahn 6 an dem Wickelkern in an sich bekannter Weise z.B. durch einen auf diesen aufgebrachten Klebestreifen angeklebt.1 shows a fully wound roll 5 resting on two support rolls 3 and 4 of a support roll winding machine. The incoming web 6, which partially wraps around the support roll 3, has not yet been separated from the finished roll 5. A separating device has already been brought up between the two supporting rollers 3 and 4 in the gusset formed between the supporting rollers 3 and 4 and the winding 5. The separating device consists of a bar 7 guided on both sides, which has at its upper end a pivotably arranged blade carrier 8, to which a tear-off blade 9 is screwed. In the blade carrier 8 are spaced from the tear-off blade 9 designed as bolts holding members 10 screwed across the width of the blade. The holding members 10 carry on their ends facing the support roller 3 felt pads 11. The blade support 8 can by means of lateral Linkage 12, which engage on levers 13 fixedly attached to the carrier, are pivoted against the support rollers 3 (FIGS. 2 and 3). In this operating position, the holding members 10 clamp the web 6 firmly against the support roller 3, while a small gap s remains between the tear-off edge of the blade 9 and the web 6. Only when the winding 5 is moved by the squeezing roller 14 over the second support roller 4, the web 6 comes to rest against the tear-off edge of the tear-off blade 9, which can be toothed in a manner known per se as a perforated edge. The web 6 tears off the finished roll 5 and the latter can be conveyed on. Now a vacuum is applied within the support roller 3, which holds the separated web of material through bores 15 in the support roller shell, so that the tear-off blade 9 can be pivoted away from the web and the entire separating device can be lowered again to provide space for a new winding core to be inserted into the gusset create, which then holds the incoming web against the support roller 3. At the start of winding, the web 6 is glued to the winding core in a manner known per se, for example by means of an adhesive strip applied to it.

Ganz entscheidend ist, daß der Klingenträger 8 als Doppelhebel ausgebildet ist. Er umfaßt zwei Hebelarme 8a und 8b, wie man aus Fig. 3 erkennt. Er ist an Balken 7 (oben auch "Platte" genannt) angelenkt - siehe Gelenk 20. Dabei hat Hebelarm 8b eine Stützfläche 21. Diese ist in Bezug auf die Längsachse von Klingenträger 8 leicht angeschrägt, und zwar derart, daß sie im Betriebszustand gemäß Fig. 3 - somit im Augenblick des Schneidens - mehr oder minder satt an der Mantelfläche 22 von Tragwalze 4 anliegt. Beim Ausstoßen des Wickels 5 aus dem Wickelbett, so wie in Fig. 2 gezeigt, tritt in Bahn 6 zwischen der Klinge 9 und der Ausdrückrolle 14 eine Zugspannung auf. Diese wirkt über die Klinge 9 auf den Klingenträger 8 in dem Sinne, daß sie diesen im Uhrzeigersinne um Gelenk 20 zu verschwenken versucht. Dies ist jedoch aufgrund der erfindungsgemäßen Ausbildung nicht möglich, und zwar wegen der Abstützung der Stützfläche 21 von Hebelarm 8b an der Anschlußfläche 22 von Tragwalze 4. Aus diesem Grunde ist aber auch eine Verbiegung des Balkens 7 nicht möglich. Der Balken bleibt vielmehr völlig gerade, so daß auch bei steifen, kartonähnlichen Papieren kein Verbiegen des Balkens 7 eintritt, und daher die Bahn 6 durch die Klinge 9 sauber durchtrennt wird.It is very important that the blade carrier 8 is designed as a double lever. It comprises two lever arms 8a and 8b, as can be seen from Fig. 3. It is articulated on beam 7 (also called "plate" above) - see joint 20. Lever arm 8b has a support surface 21. This is slightly beveled with respect to the longitudinal axis of blade carrier 8, in such a way that in the operating state according to FIG 3 - thus at the moment of cutting - more or less fully abuts against the lateral surface 22 of the supporting roller 4. When the winding 5 is ejected from the winding bed, as shown in FIG. 2, a tension occurs in the web 6 between the blade 9 and the pressing roller 14. This acts via the blade 9 on the blade carrier 8 in the sense that it tries to pivot it clockwise around the joint 20. However, this is not possible due to the design according to the invention, namely because of the support of the support surface 21 of the lever arm 8b on the connection surface 22 of the support roller 4. For this reason, however, a bending of the beam 7 is not possible. Rather, the bar remains completely straight, so that even with stiff, cardboard-like papers there is no bending of the bar 7, and therefore the web 6 is cut cleanly by the blade 9.
