Abstract

A device for winding or rewinding a paper web employs an apparatus (18) for moving the wound winding core from the winding station (A) to a position (B) in such a way that then the course of the paper web, which is still arriving, is such that the newly supplied winding core sinks into the paper web, and, after a corresponding cutting operation, the winding-on operation onto the empty winding core can be carried out by this means in a particularly simple manner. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum kontinuierlichen Auf- oder Umrollen einer Papierbahn auf einen Wickelkern, mit einem Grundgestell, mit an der Wickelstelle befindlichen Drehlagerungsaufnahmen, die mit einem Antrieb bestückt und für die entgegengesetzten freien Enden des Wickelkerns bestimmt sind, einer lageveränderbaren Andrückwalze für das Anlegen an die Umfangsfläche des Wickelkerns, bzw. der gewickelten Papierrolle, einer Schneideinrichtung zum Schneiden der Papierbahn, einer Einrichtung zum Bewegen des bewickelten Wickelkerns weg von den Drehlagerungsaufnahmen, einer Einrichtung zum Anlegen der geschnittenen Papierbahn an einen leeren Wickelkern, und mit einer Einrichtung zum Eingeben eines leeren Wickelkerns in die Drehlagerungsaufnahme.The invention relates to a device for the continuous reeling or rewinding of a paper web onto a winding core, with a base frame, with rotary bearing receptacles located at the winding point, which are equipped with a drive and are intended for the opposite free ends of the winding core, a position-changeable pressure roller for the application to the circumferential surface of the winding core or the wound paper roll, a cutting device for cutting the paper web, a device for moving the wound winding core away from the rotary bearing receptacles, a device for applying the cut paper web to an empty winding core, and with a device for Enter an empty winding core in the rotary bearing holder.

Eine derartige Vorrichtung ist aus der DE-OS 36 30 744 bekannt. Bei dieser Vorrichtung wird ein Andrückarm verwendet, an dessem freien Ende eine Umlenkrolle angebracht ist. Dieser Andrückarm ist zwischen einer oberen und unteren Stellung bewegbar, so daß die Bahnkurve des Andrückarmes zwischen der Andrückwalze und dem die Papierbahn aufwickelnden Wickelkern verläuft. Die Papierbahn ist derart um den Andrückarm geführt, daß in der unteren Stellung des Armes und in der Offenstellung der Andrückwalzeneinheit die Papierbahn von dem Arm unterhalb eines Spaltes für die Papierbahn gehalten wird.Such a device is known from DE-OS 36 30 744. In this device, a pressure arm is used, on the free end of which a deflection roller is attached. This pressure arm can be moved between an upper and lower position, so that the path curve of the pressure arm runs between the pressure roller and the winding core winding the paper web. The paper web is guided around the pressure arm such that in the lower position of the arm and in the open position of the pressure roller unit, the paper web is held by the arm below a gap for the paper web.

Eine bei der Andrückwalzeneinheit sich befindende Messerstange erzeugt einen Längsschnitt, der etwa 150 mm von der Kante der Papierbahn entfernt liegt. Ein im Untergestell erzeugter Druckluftstrom zieht den Streifen auf den leeren Wickelkern auf. Daraufhin bewegt sich die Messerstange quer über die ganze Papierbahn, so daß die Bahn vollständig auf den Wickelkern aufgezogen wird.A knife bar located on the pressure roller unit produces a longitudinal cut that is approximately 150 mm from the edge of the paper web. A stream of compressed air generated in the base draws the strip onto the empty winding core. The knife bar then moves across the entire paper web, so that the web is completely drawn onto the winding core.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung der eingangs genannten Art dahingehend zu schaffen, daß mit einfacheren konsttruktiven Mitteln im Sinne eines kontinuierlichen Aufroll- oder Umrollvorganges ein optimaler Übergang des Wickelvorganges von der vollen Papierrolle auf einen neuen, leeren Wickelkern ermöglicht wird.The object of the invention is to provide a device of the type mentioned in such a way that an optimal transition of the winding process from the full paper roll to a new, empty winding core is made possible with simpler constructional means in the sense of a continuous winding or rewinding process.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Einrichtung zum Bewegen des bewickelten Wickelkerns mit ihrem den Wickelkern erfassenden Teil aus der Wickelstelle an eine Stelle bewegbar ist, in der der Verlauf der auf die Papierrolle weitergewickelten Papierbahn in Verlaufsrichtung vor der Papierrolle derart ist, daß dort ein in die Drehlagerungsaufnahmen eingelegter leerer Wickelkern beim Einlegen mit der laufenden Papierbahn zumindest in Berührung gelangt.This object is achieved according to the invention in that the device for moving the wound winding core, with its part which grips the winding core, can be moved out of the winding location to a point in which the course of the paper web wound on the paper roll in the direction of travel in front of the paper roll is such that there an empty winding core inserted into the rotary bearing receptacles at least comes into contact with the running paper web during insertion.

Dadurch, daß durch das Wegbewegen des bewickelten Wickelkerns, d.h. des Wickelkerns mit der Papierrolle in eine Abführbereitschaftsstellung und dadurch, daß in dieser Stellung die Papierbahn vor der Papierrolle mit dem leeren Wickelkern bereits in Berührung gelangt, kann nach dem eingeleiteten Schneidvorgang der Papierbahn ohne zusätzliche Hilfsmittel der Anwickelvorgang der Papierbahn an den leeren Wickelkern auf die an sich bekannte Weise vorgenommen werden, d.h. die Abführbewegung des mit der Papierrolle versehenen Wickelkerns wird dazu ausgenutzt, die zulaufende Papierbahn zu verlagern, und zwar derart im Verhältnis zu den Drehlagerungsaufnahmen, daß beim Einlegen des leeren Wickelkems dieser mit seiner Umfangsfläche mit der der Papierrolle zulaufenden Papierbahn in Berührung gelangt, was den Anwickelvorgang fördernd beeinflußt.By moving the wound core, i.e. of the winding core with the paper roll in a ready-to-discharge position and in that in this position the paper web already comes into contact with the empty winding core in front of the paper roll, after the initiated cutting process of the paper web, the winding process of the paper web on the empty winding core can be carried out without additional aids known way to be made, ie the removal movement of the winding core provided with the paper roll is used to shift the incoming paper web, in such a way in relation to the rotary bearing receptacles that when the empty winding core is inserted, its circumferential surface comes into contact with the paper web running towards the paper roll, which causes the winding process encouragingly influenced.

Vorzugsweise lenkt ein in die Drehlagerungsaufnahmen eingelegter leerer Wickelkern die auf die Papierrolle weitergewickelte Papierbahn sogar ab, so daß der leere Wickelkern die Papierbahn bereits berührt, bevor dieser endgültig in die Drehlagerungsaufnahmen eingelegt ist mit der Folge, daß die Papierbahn in zunehmendem Maße bis zum endgültigen Einlegen in die Drehlagerungsaufnahmen den leeren Wickelkern umschlingt und durch die dadurch auftretende Reibung den Wickelkern am Umfang mitnimmt und in Drehung versetzen kann. Dies fördert im weiteren Umfang den Anwickelvorgang.Preferably, an empty winding core inserted into the rotary bearing receptacles even deflects the paper web wound onto the paper roll, so that the empty winding core already touches the paper web before it is finally inserted into the rotary bearing receptacles, with the result that the paper web is increasingly used until it is finally inserted wrapped around the empty winding core in the rotary bearing receptacles and the resulting friction Takes the winding core along the circumference and can set it in rotation. This further promotes the start-up process.

Zweckmäßigerweise ist die Einrichtung zum Bewegen des bewickelten Wickelkerns als Schwenkarm ausgebildet. Dieser Schwenkarm ist mit zwei Haltegabeln für die entgegengesetzten freien Enden des Wickelkerns versehen. Durch diese Schwenkbewegung ist es auf besonders einfache Weise möglich, unter Aufrechterhaltung der Wandspannung bei weiterlaufender Papierbahn die gewünschte Verlagerung der Papierrolle vorzunehmen.The device for moving the wound winding core is expediently designed as a swivel arm. This swivel arm is provided with two holding forks for the opposite free ends of the winding core. This pivoting movement makes it possible in a particularly simple manner to carry out the desired displacement of the paper roll while maintaining the wall tension while the paper web continues to run.

Damit der Schwenkvorgang auch vorgenommen werden kann, wenn die freien Enden des Wickelkerns insbesondere in der Wickelstellung den Gabeln im Wege steht, kann zumindest ein Gabelteil der Haltegabel schwenkbar angeordnet sein. Damit beim Bewegen der Papierrolle aus der Wickelstellung in die zweite Stellung ein Weiterdrehbetrieb der Papierrolle bzw. des Wickelkerns möglich ist, ist diese Einrichtung zum Bewegen des bewickelten Wickelkerns mit einem Antriebsmotor (Hilfsmotor) versehen.So that the pivoting process can also be carried out when the free ends of the winding core, particularly in the winding position, stands in the way of the forks, at least one fork part of the holding fork can be arranged pivotably. So that when the paper roll is moved from the winding position into the second position, further operation of the paper roll or the winding core is possible, this device for moving the wound winding core is provided with a drive motor (auxiliary motor).

Gemäß dem erläuterten Stand der Technik wird durch die Schneideinrichtung ein Randstreifen längsgeschnitten und dann aus der Papierbahn von einer Blaseinrichtung abgetrennt und um den sich drehenden leeren Wickelkern gelegt, wonach durch eine Querbewegung der Schneideinrichtung ein Querdurchtrennen der gesamten Papierbahn erfolgt. Es ist von Vorteil, diese Schneideinrichtung mit zwei parallelen Schneiden mittig anzuordnen und somit aus der Mitte der Bahn den entsprechenden Streifen herauszuschneiden, da dadurch ein sichereres Anwickeln mit dem danach folgenden Querdurchtrennen gewährleistet werden kann.According to the explained prior art, an edge strip is cut lengthwise by the cutting device and then separated from the paper web by a blowing device and placed around the rotating empty winding core, after which a transverse cutting of the entire paper web takes place by a transverse movement of the cutting device. It is advantageous to arrange this cutting device in the middle with two parallel cutting edges and thus to cut out the corresponding strip from the middle of the web, since this ensures a more reliable winding with the subsequent transverse cutting.

Die Erfindung wird nachfolgend anhand der beigefügten Zeichnung, bzw. einer darin rein schematisch dargestellten Vorrichtung zum Auf- oder Umrollen einer Papierbahn näher erläutert.The invention is explained in more detail below with the aid of the attached drawing, or a device for rolling up or rewinding a paper web, shown purely schematically therein.

Dieser Schwenkhebel 18 befindet sich natürlich auf beiden Seiten des Wickelkerns und ist mit einer Aufnahmegabel 24 versehen, deren linkes Gabelteil 26 mittels eines hydraulischen oder pneumatischen Zylinders 28 schwenkbar angeordnet ist, was durch ausgezogene und strichpunktierte Linien angedeutet ist.The winding station A is assigned a swivel arm 18 downstream of the paper path, which can be swiveled about a lower swivel axis 20 from a dot-dash position shown in the drawing into the extended position by means of a hydraulic or pneumatic cylinder 22. This pivot lever 18 is of course located on both sides of the winding core and is provided with a receiving fork 24, the left fork part 26 is pivotally arranged by means of a hydraulic or pneumatic cylinder 28, which is indicated by solid and dash-dotted lines.

In der ausgezogenen Stellung der Schwenkhebel 18 sind die freien Lagerenden 14 des Wickelkerns 18 auf einer Ablage 30 abgelegt, auf der die bewickelten Wickelkerne für das Abgeben derselben mit einer Papierrolle 32 gerollt werden können, und zwar aus der durch B gekennzeichneten Stelle in die durch D gekennzeichnete Stelle.In the extended position of the pivot lever 18, the free bearing ends 14 of the winding core 18 are placed on a tray 30, on which the wound winding cores can be rolled with a paper roll 32 for dispensing them, namely from the position indicated by B into the position indicated by D marked place.

Oberhalb der Wickelstation A befindet sich ein Magazin 34 für leere Wickelkerne 16, wobei sich jeweils immer ein Wickelkern 16 an einer Bereitschaftsstelle C befindet.Above the winding station A there is a magazine 34 for empty winding cores 16, with a winding core 16 always being at a standby point C.

Stromauf der Wickelstation A befindet sich eine Wickelkernzuführeinrichtung mit einem ersten Hebel 36, der bei 38 angelenkt und durch einen hydraulischen oder pneumatischen Zylinder 40 aus der ausgezogenen Stellung in die strichpunktierte Stellung bewegbar ist. Die Wickelkernzuführeinrichtung 35 weist einen am ersten Hebel 36 bei 42 angelenkten zweiten Hebel 44 auf, an dessen freiem Ende sich eine Gabel 46 mit einem schwenkbaren Teil 48 befindet. Diese Hebelanordnung der Wickelkernzuführeinrichtung 35 befindet sich natürlich wiederum beidseitig des Wickelkerns, um die jeweiligen Enden 14 des Wickelkerns erfassen zu können. Der zweite Hebel 44 ist mittels des hydraulischen oder pneumatischen Zylinders 48 um die Achse 42 schwenkbar, wie dies in strichpunktierten Linien in zwei Stellungen dargestellt ist.Upstream of the winding station A there is a winding core feed device with a first lever 36 which is articulated at 38 and can be moved from the extended position into the dash-dotted position by a hydraulic or pneumatic cylinder 40. The winding core feed device 35 has a second lever 44 articulated on the first lever 36 at 42, at the free end of which there is a fork 46 with a pivotable part 48. This lever arrangement of the winding core feed device 35 is of course located on both sides of the winding core in order to be able to grasp the respective ends 14 of the winding core. The second lever 44 can be pivoted about the axis 42 by means of the hydraulic or pneumatic cylinder 48, as is shown in two positions by dash-dotted lines.

Weiterhin stromauf der Wickelstation A befindet sich ein weiterer Schwenkhebel 50, der mittels eines hydraulischen oder pneumatischen Zylinders 52 aus einer strichpunktierten Stellung in eine ausgezogene Stellung um die Schwenkachse 54 schwenkbar ist. An diesem Hebel 50 befindet sich eine Andrückrolle 56, die die Papierbahn zunächst gegen den Wickelkern 16 drückt und während des Wickelns auf der Oberfläche des entstehenden Wickels (Papierrolle 32) aufliegt, um einen einwandfreien Wickelvorgang gewährleisten zu können. An dem Hebel 50 befindet sich auch ein Spitzenschneider 58 zum Längs- und Querschneiden der Papierbahn.Further upstream of the winding station A there is a further pivot lever 50 which can be pivoted about a pivot axis 54 from a dash-dotted position into an extended position by means of a hydraulic or pneumatic cylinder 52. On this lever 50 there is a pressure roller 56 which first presses the paper web against the winding core 16 and rests on the surface of the resulting winding (paper roll 32) during winding in order to be able to ensure a perfect winding process. There is also a tip cutter 58 on the lever 50 for longitudinal and transverse cutting of the paper web.

Wenn in der Wickelstation A der Wickel 32 fertiggestellt ist, so wird der Hebel 50 im Gegenuhrzeigersinn in die strichpunktierte Stellung verschwenkt, in der die Andrückrolle 56 von dem Wickel 32 abgehoben ist. Dabei nimmt die Papierbahn den Verlauf P′ und P˝. In dieser Stellung wird der Schwenkhebel 18 aus der ausgezogen dargestellten Stellung entgegen dem Uhrzeigersinn in die strichpunktierte Stellung bewegt, wobei der Gabelteil 26 sich in der Stellung 26′ befindet, um die Enden 14 des Wickelkerns zu erfassen, wozu die Gabel 24 geschlossen wird. Ein am Schwenkhebel 18 befindlicher Hilfsantrieb (nicht dargestellt) besorgt dann den Weiterantrieb der Papierrolle mit einer reduzierten Geschwindigkeit von beispielsweise 10 bis 40 m/min. Dann wird der Schwenkhebel 18 zusammen mit dem bewickelten Wickelkern 16 im Uhrzeigersinn in die ausgezogene Stellung verschwenkt. In dieser Stellung nimmt die Papierbahn den Verlauf P′, P˝ ′,d.h. deutlich auf der in der Zeichnung rechten Seite des Zentrums Z der Wickelstation A, und zwar bei Aufrechterhaltung der Bahnspannung.When the winding 32 is completed in the winding station A, the lever 50 is pivoted counterclockwise into the dot-dash position in which the pressure roller 56 is lifted off the winding 32. The paper web takes the course P 'and P˝. In this position, the pivot lever 18 is moved from the position shown in the counterclockwise direction to the dash-dotted position, the fork part 26 is in the position 26 'to detect the ends 14 of the winding core, for which purpose the fork 24 is closed. An auxiliary drive (not shown) located on the swivel lever 18 then ensures the further drive of the paper roll at a reduced speed of, for example, 10 to 40 m / min. Then the pivot lever 18 is pivoted together with the wound winding core 16 clockwise into the extended position. In this position, the paper web takes the course P ', P˝', ie clearly on the right side of the center Z of the winding station A in the drawing, while maintaining the web tension.

Wenn der leere Wickelkern auf eine Geschwindigkeit vorbeschleunigt wird, so kann auch mit einer höheren Bahngeschwindigkeit während des Wechselns weitergefahren werden.If the empty winding core is pre-accelerated to a speed, it is possible to continue at a higher web speed during the change.

Die Wickelkernzuführeinrichtung 35 bringt nun einen leeren Wickelkern 16 in die Drehlagerungsaufnahmen 12. Dabei taucht der Wickelkern 16 in den Verlauf der Papierbahn P˝ ′ein und lenkt den Papierverlauf ab in den Verlauf P˝˝. Dabei kann die weiterlaufende Papierbahn durch Reibung den Wickelkern bereits in Drehung versetzen, was insbesondere bei reduzierter Bahngeschwindigkeit realisierbar ist.The winding core feed device 35 now brings an empty winding core 16 into the rotary bearing receptacles 12. The winding core 16 dips into the course of the paper web Pbahn 'and deflects the paper course into the course P˝˝. The running paper web can already set the winding core in rotation by friction, which is particularly feasible with a reduced web speed.

Dann wird die Andrückrolle 56 auf den Umfang des leeren Wickelkerns 16 aufgelegt, und der Spitzenschneider 58 schneidet entweder in der Mitte oder am Rand einen ca. 10 cm breiten Streifen durch Längsschneiden, welcher Streifen durch die Blaseinrichtung 60 abgetrennt und um den Wickelkern 16 gelegt wird, was durch das Eintauchen des Wickelkerns in die Papierbahn unmittelbar ohne zusätzliche Maßnahmen möglich ist.Then the pressure roller 56 is placed on the circumference of the empty winding core 16, and the tip cutter 58 cuts either in the middle or at the edge an approximately 10 cm wide strip by slitting, which strip is separated by the blowing device 60 and placed around the winding core 16 , which is possible by immersing the winding core in the paper web directly without additional measures.

Nach erfolgtem Überführen des Streifens der Papierbahn auf den Wickelkern 16 schneidet der Spitzenschneider den Streifen sofort "breit", womit die Papierbahn vollständig auf den leeren Wickelkern aufgewickelt wird. Danach kann die Bahngeschwindigkeit wieder gesteigert werden, und die volle Papierrolle kann von der Stelle B in die Stelle D und von dort abgegeben werden.After the strip of the paper web has been transferred onto the winding core 16, the tip cutter immediately cuts the strip "wide", with which the paper web is completely wound onto the empty winding core. The web speed can then be increased again, and the full paper roll can be delivered from point B to point D and from there.

Dieser Vorgang wiederholt sich jedes Mal, wenn eine volle Papierrolle hergestellt worden ist.This process is repeated every time a full roll of paper has been made.

Ein derartiger Vorgang ist sowohl hinsichtlich eines allgemeinen Aufrollens als auch hinsichtlich eines Umrollens möglich. Insbesondere schließt sich eine derartige Vorrichtung an einen Kalander oder Superkalander an.Such an operation is both in terms of general reeling as well possible with respect to a roll. In particular, such a device connects to a calender or supercalender.
