Description

Die Erfindung betrifft eine Vorrichtung zum Aufwickeln insbesondere von mit Klebstoff beschichteten Warenbahnen auf einen Wickelkern, mit einer ortsfest gelagerten ersten Walze, über die die Warenbahn zuläuft und auf deren Umfang sich der Wickel entlang einer ersten Berührungslinie abstützt, ferner mit einer zweiten Walze, auf deren Umfang sich der Wickel entlang einer zweiten Berührungslinie abstützt und mit einer dritten, entlang einer dritten Berührungslinie auf dem Wickel aufliegenden Walze, wobei die Lage der zweiten und dritten Walze in Abhängigkeit vom Wickeldurchmesser verstellbar ist.The invention relates to a device for winding in particular of adhesive-coated webs on a winding core, with a fixed first roller, over which the web runs and on the circumference of which the roll is supported along a first line of contact, further with a second roller, on the The winding is supported circumferentially along a second line of contact and with a third roller resting on the winding along a third line of contact, the position of the second and third rollers being adjustable depending on the winding diameter.

Bei einer bekannten Vorrichtung dieser Art (DE-OS 25 22 011) ist unterhalb der ersten und zweiten Walze noch eine vierte Walze angeordnet. Mit zunehmendem Wickeldurchmesser entfernt sich die zweite Walze von der ersten Walze und es entsteht zwischen diesen beiden Walzen ein sich ständig vergrößernder Durchtrittsspalt. Der größer werdende Wickel wird mit Hilfe der dritten Walze nach unten gedrückt und wandert durch den Durchtrittsraum hindurch, bis er mit seiner Unterseite auf der schwenkbar angeordneten vierten Walze aufsitzt.In a known device of this type (DE-OS 25 22 011), a fourth roller is arranged below the first and second roller. As the winding diameter increases, the second roller moves away from the first roller and a continuously increasing passage gap is created between these two rollers. The larger roll is pressed down with the help of the third roller and moves through the passage space until its underside is on the fourth roller arranged pivotably.

Der geschilderte Bewegungsablauf der verschiedenen Walzen wird über Kurvenscheiben gesteuert.The movement sequence described for the various rollers is controlled via cam disks.

Die bekannte Vorrichtung ist zum Wickeln von problematischen Warenbahnen, insbesondere zum Wickeln von mit Klebstoff beschichteten Warenbahnen nicht geeignet. Bei problematisch zu wickelnden Warenbahnen muß nämlich angestrebt werden, daß sich die Berührungslinien des Wickels mit den erwähnten drei Walzen über den gesamten Walzendurchmesser möglichst nicht am Umfang verlagern. Die besten Wickelergebnisse werden erzielt, wenn die von der Wickelachse und den Berührungslinien des Wickelkerns mit den drei Walzen bestimmten Ebenen während des gesamten Wickelvorgangs gleichbleibende Winkel miteinander einschließen. Diese anzustrebende Bedingung ist in der Praxis nur unzureichend erfüllbar, weil sich für eine Verwirklichung dieser Forderung der Abstand der drei verschiedenen Walzen während des gesamten Wickelvorgangs stets im gleichen Maß ändern müßte. Eine solche theoretisch günstige Konstruktion erfordert jedoch einen sehr hohen konstruktiven Aufwand. Bei der bekannten Lösung (DE-OS 25 22 011) ist die Erfüllung der theoretisch einzuhaltenden Forderung völlig ausgeschlossen. Durch die geschilderte Konstruktion erfolgt die Verlagerung der Berührungslinien zwischen den Walzen und dem Wickel im Verlauf des Wickelvorgangs um einen besonders großen Betrag. Mit einer derartigen Vorrichtung könnte man demzufolge ohne unerwünschte Faltenbildung, Lufteinschlüsse oder andere Unzuträglichkeiten jedenfalls mit Klebstoff beschichtete Warenbahnen nicht ordnungsgemäß wickeln.The known device is not suitable for winding problematic webs, in particular for winding webs coated with adhesive. In the case of webs of goods to be wound with problems, the aim must be that the contact lines of the roll with the three rolls mentioned do not shift as far as possible over the entire roll diameter. The best winding results are achieved if the planes defined by the winding axis and the lines of contact of the winding core with the three rollers enclose constant angles during the entire winding process. In practice, this desired condition can only be met inadequately because the distance between the three different rollers would have to change to the same extent during the entire winding process in order to meet this requirement. Such a theoretically favorable construction, however, requires a very high level of design effort. In the known solution (DE-OS 25 22 011) the fulfillment of the theoretical requirement can be completely ruled out. Due to the construction described, the contact lines between the rollers and the winding are shifted by a particularly large amount in the course of the winding process. With such a device it would consequently not be possible to properly wrap webs coated with glue without undesirable wrinkling, air pockets or other inconveniences.

Es sind ferner auch Wickelvorrichtungen bekannt, bei denen statt der zweiten Walze ein umlaufendes Band vorgesehen ist. Auch bei dieser Konstruktion tritt ein unerwünschtes Wandern der Berührungslinien im Verlauf des Wickelvorgangs ein. Bei dieser bekannten Konstruktion ist es ferner nachteilig, daß mit größer werdendem Wickeldurchmesser die Berührungslinie zwischen dem Wickel und dem Wickelband ständig weiter in den freien, nicht von der Umlenkrolle unterstützten Bereich des Wickeltuchs wandert. Hierdurch entstehen nicht genau definierte Wickelverhältnisse.Winding devices are also known, in which a rotating belt is provided instead of the second roller. With this construction, too, an undesirable migration of the contact lines occurs in the course of the winding process. In this known construction, it is also disadvantageous that, as the winding diameter increases, the line of contact between the winding and the winding tape constantly moves further into the free area of the winding blanket which is not supported by the deflection roller. This creates winding conditions that are not precisely defined.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs erwähnten Art so auszubilden, daß sie mit verringertem Aufwand die möglichst weitgehende Einhaltung der Forderung ermöglicht, daß die Berührungslinien zwischen Wickel und Walzen sich mit zunehmendem Wickeldurchmesser in einem nur unschädlichen Maße verlagern. Außerdem soll die an den Berührungslinien der ersten und zweiten Walze übertragene Andruckkraft möglichst während des gesamten Wickelvorgangs annähernd gleich bleiben.The invention has for its object to provide a device of the type mentioned in such a way that it allows the greatest possible compliance with the requirement that the lines of contact between the winding and rollers shift with an increasing winding diameter to an innocuous extent with reduced effort. In addition, the pressure force transmitted at the contact lines of the first and second rollers should remain approximately the same as far as possible during the entire winding process.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß die Andruckkraft der dritten Walze entsprechend dem zunehmenden Wickeldurchmesser verringert wird und sich die zweite Walze entlang einer geradlinigen Führungsbahn bewegt, wobei die durch die Wickelachse und die Berührungslinien verlaufenden Ebenen über den gesamten Wickeldurchmesser zumindest annähernd gleiche Winkel zueinander bilden und die Lagerung der zweiten Walze auf einem Schwenkarm angeordnet ist, auf dem sie mittels Stellmotor verschiebbar ist.This object is achieved according to the invention in that the pressing force of the third roller is reduced in accordance with the increasing winding diameter and the second roller moves along a straight guide path, the planes running through the winding axis and the lines of contact over the entire winding diameter at least approximately equal angles to one another form and the storage of the second roller is arranged on a swivel arm on which it is displaceable by means of a servomotor.

Mit einer derartigen Vorrichtung wird erreicht, daß während des gesamten Wickelvorgangs zwei Einflußfaktoren, nämlich die Lage der Berührungslinie und der Kontaktliniendruck praktisch unverändert bleiben. Hierdurch wird eine faltenfreie Führung der Materialbahn und das Vermeiden von Lufteinschlüssen an der Schneidwalze ermöglicht.With such a device it is achieved that two influencing factors, namely the position of the contact line and the contact line pressure remain practically unchanged during the entire winding process. This enables wrinkle-free guidance of the material web and the avoidance of air pockets on the cutting roller.

Eine Warenbahn 1 läuft über ein Saugband 4 und über eine erste Walze 3 auf einen Wickelkern 2. Oberhalb der ersten Walze 3 ist ein Querschneider 5 angeordnet, der von einem nicht dargestellten Längenzähler geschaltet wird und die Warenbahn nach Erreichen des vorgegebenen Wickeldurchmessers trennt. Der nicht dargestellte Längenzähler gibt gleichzeitig ein Signal zum Stopp des Saugbandes 4. Die durch den Stopp des Saugbandes 4 entstehende Schlaufe der Warenbahn 1 wird beispielsweise über eine nicht dargestellte Pendelwalze gespeichert. Der Umlauf der ersten Walze 3 wird durch den Ab-schneidevorgang nicht beeinflußt.A material web 1 runs over a suction belt 4 and over a first roller 3 onto a winding core 2. Above the first roller 3, a cross cutter 5 is arranged, which is switched by a length counter, not shown, and separates the material web after reaching the predetermined winding diameter. The length counter, not shown, simultaneously gives a signal to stop the suction belt 4. The suction belt 4 that arises when the suction belt 4 stops Loop of the web 1 is stored, for example, via a pendulum roller, not shown. The rotation of the first roller 3 is not influenced by the A b cutting process.

Der Wickelkern 2 stützt sich entlang dreier Berührungslinien an der ersten Walze 3, der zweiten Walze 6 und der dritten Walze 7 ab. Die dritte Walze 7 ist als Andruckwalze ausgebildet, deren Lage über Hebel 8 mittels eines Stellmotors 9 verstellbar ist. Der Stellmotor ist in der Praxis meistens eine pneumatische Kolben-Zylinder-Einheit.The winding core 2 is supported along three lines of contact on the first roller 3, the second roller 6 and the third roller 7. The third roller 7 is designed as a pressure roller, the position of which can be adjusted via lever 8 by means of a servomotor 9. In practice, the servomotor is mostly a pneumatic piston-cylinder unit.

Die zweite Walze 6 ist beidseitig in einem spitzwinklig geneigt geführten Lagerschild 10 gelagert. Die Führung des Lagerschilds 10 und damit die Bewegungsbahn des Lagerschilds 10 verläuft etwa unter 300 zur Horizontalen. Das Lagerschild 10 wird mittels eines Stellmotors 11 verstellt.The second roller 6 is supported on both sides in a bearing plate 10 which is inclined at an acute angle. The guidance of the bearing plate 10 and thus the path of movement of the bearing plate 10 runs approximately below 30 ° to the horizontal. The bearing plate 10 is adjusted by means of a servomotor 11.

Die Parallelführung der zweiten Walze 6 erfolgt über beidseitig vorgesehene Zahnstangen, die auf ebenfalls beidseitig angeordneten Schwenkarmen 13 vorgesehen sind. Die beidseitigen Lagerschilde 10 tragen miteinander gekoppelte Zahnräder 12a, die auf den zugehörigen Zahnstangen 12 ablaufen. Die Lagerschilde 10 werden zusätzlich in nicht dargestellten Kugelbuchsen geführt.The second roller 6 is guided in parallel via toothed racks provided on both sides, which are provided on swivel arms 13 likewise arranged on both sides. The bearing plates 10 on both sides carry gears 12 a which are coupled to one another and run on the associated racks 12. The end shields 10 are additionally guided in ball bushings, not shown.

Die Schwenkarme 13 sind um die Achse 13a verschwenkbar gelagert und können mit Hilfe des Stellmotors 14, der am fest mit dem Schwenkarm 13 verbundenen Hebel 13a angreift, verschwenkt werden.The pivot arms 13 are pivotally mounted about the axis 13a and can be pivoted with the aid of the servomotor 14, which engages on the lever 13a fixedly connected to the pivot arm 13.

Die Lage der Lagerschilde 10 und damit die Lage der zweiten Walze 6 wird in Richtung auf die erste Walze 3 über unterschiedlich lange Anschlagbolzen 15 begrenzt, die auf einer verdrehbaren Anschlagscheibe sitzen. Die unterschiedlich langen Abschlagbolzen 15 sind für unterschiedliche Hülsendurchmesser vorgesehen.The position of the end shields 10 and thus the position of the second roller 6 is in the direction of the first roller 3 limited by stop pins 15 of different lengths, which sit on a rotatable stop disk. The differently long tapping bolts 15 are provided for different sleeve diameters.

Eine Fotozelle 17 ist in einer nur schematisch angedeuteten, am Schwenkarm 13 festen Geradeführung 22 geführt. Die Fotozelle 17 wird von einer Gabel 21 mitgenommen, die um das Lager 25 am Schwenkarm 13 verschwenkt wird. Die Mitnahme der Gabel erfolgt durch einen Ansatz oder eine Führungsnut an der Achse der zweiten Walze 6. Die Fotozelle 17 tastet den Wickeldurchmesser ab und gibt über nicht dargestellte Verstärker ein Stellsignal an den Stellmotor 11, der das Lagerschild 10 und damit die zweite Walze 6 entsprechend der Durchmesserzunahme des Wickels 20 verstellt.A photocell 17 is guided in a straight guide 22, which is only indicated schematically and is fixed on the swivel arm 13. The photocell 17 is carried by a fork 21 which is pivoted about the bearing 25 on the swivel arm 13. The fork is carried by a shoulder or a guide groove on the axis of the second roller 6. The photocell 17 scans the winding diameter and sends an actuating signal to the servomotor 11 via an amplifier (not shown), which corresponds to the end shield 10 and thus the second roller 6 adjusted the diameter increase of the winding 20.

Oberhalb der dritten Walze befindet sich ein Hülsenmagazin 18 mit den bereitliegenden Wickelkernen 2a für einen Rollenwechsel. Unterhalb der Walzen und des Schwenkarms befindet sich ein Ablageblech 19, welches die fertigen Wickel 20 aufnimmt.Above the third roller there is a sleeve magazine 18 with the winding cores 2a ready for a roll change. Below the rollers and the swivel arm there is a storage plate 19 which receives the finished rolls 20.

In Figur 2 ist ein Wickel 20 dargestellt, der bis auf den Restbereich 19, welcher vom Querschneider 5 von der Warenbahn 1 getrennt wurde, fertig gewickelt ist. Aus Figur 2 ist ferner ersichtlich, daß die Fotozelle 17 mit der schwenkbaren Gabel 21 in eine dem Wickeldurchmesser entsprechende Stellung gewandert ist.FIG. 2 shows a winding 20, which is completely wound except for the remaining area 19, which was separated from the web 1 by the cross cutter 5. From Figure 2 it can also be seen that the photocell 17 has moved with the pivotable fork 21 in a position corresponding to the winding diameter.

Zur Bestimmung des gewünschten Andrucks an den Wickel 20 mittels der dritten Walze 3 ist ein pneumatischer, kurvengesteuerter Feindruckregler 23 vorgesehen, der den Druck des Stellmotors 9 beeinflußt.To determine the desired pressure on the winding 20 by means of the third roller 3, a pneumatic, curve-controlled fine pressure regulator 23 is provided, which influences the pressure of the servomotor 9.

Figur 3 zeigt den freigegebenen Wickel im Fall auf das Ablageblech, ferner den zurückgeschwenkten Schwenkarm 13, die hochgeschwenkte dritte Walze 7 und den Anlauf des neuen Anfangs der Warenbahn 1. Ein neuer Wickelkern 2a liegt in Bereitstellungslage. Nach Ablage des Wickels 20 wird der neue Wickelkern 2a vom Hülsenmagazin 18 freigegeben und der Schwenkarm 13 mit der Steuerwalze 6 sowie die dritte Walze 7 schwenken nacheinander in die Ausgangspositionen gemäß Figur 1 zur Aufnahme des leeren Wickelkerns 2a.FIG. 3 shows the released reel in the case of the storage tray, furthermore the swiveled-back swivel arm 13, the swiveled-up third roller 7 and the start of the new start of the web 1. A new reel core 2a is in the ready position. After the winding 20 has been deposited, the new winding core 2a is released from the sleeve magazine 18 and the swivel arm 13 with the control roller 6 and the third roller 7 pivot successively into the starting positions according to FIG. 1 for receiving the empty winding core 2a.
