Abstract
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 on 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 peripheral 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.
Bei einer anderen bekannten Wickelmaschine (DE 15 74 426 C2) verlagert sich der Wickelkern während des Wickelns. Der Hauptantrieb für den Wickelkern muß daher beweglich gelagert sein, was Probleme in bezug auf das Gewicht und die Hydraulik mit sich bringt. Leere Wickelhülsen werden zwischen einer antreibbaren Tragwalze und einer Hilfskontaktwalze mit Hilfe von Sperrollen festgehalten. Diese Elemente überdecken einen großen Teil des Umfangs des Wickelkerns, so daß für eine Schneidvorrichtung mit zugehöriger Blasvorrichtung nur noch wenig Platz verbleibt.In another known winding machine (DE 15 74 426 C2), the winding core is shifted during winding. The main drive for the winding core must therefore be movably mounted, which causes problems in terms of weight and hydraulics. Empty winding tubes are held between a drivable carrier roller and an auxiliary contact roller with the aid of locking rollers. These elements cover a large part of the circumference of the winding core, so that only a little space remains for a cutting device with an associated blowing device.
Bei einer weiteren bekannten Wickelmaschine (EP 0 089 595 A3) gibt es eine erste Station, in der ein leerer Wickelkern mit dem Anfang eines abgeschnittenen Papierabschnitts versorgt wird, und eine zweite Station, in der der eigentliche Wickelvorgang erfolgt. Eine Umschlingung des leeren Wickelkerns durch die laufende Papierbahn wird dadurch erreicht, daß eine mit Rollen versehene Schneidvorrichtung um den Wickelkern herum geschwenkt wird.In another known winding machine (EP 0 089 595 A3) there is a first station in which an empty winding core is supplied with the beginning of a cut-off paper section, and a second station in which the actual winding process takes place. Wrapping of the empty winding core by the running paper web is achieved in that a cutting device provided with rollers is pivoted around the winding core.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, bei der im Sinne eines kontinuierlichen Aufroll- oder Umrollvorgangs ein optimaler Übergang des Wickelvorgangs von der vollen Papierrolle auf einen neuen, leeren Wickelkern ermöglicht wird.The invention has for its object to provide a device of the type mentioned, in which an optimal transition of the winding process from the full paper roll to a new, empty winding core is made possible in the sense of a continuous winding or rewinding process.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
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 Wickelkerns dieser mit seiner Umfangsfläche mit der der Papierrolle zulaufenden Papierbahn weitgehend frei in Berührung gelangt. Dies wird dadurch erreicht, daß der Wickelkern nicht durch Trag- und Hilfskontaktwalzen oder Sperrollen gelagert wird, sondern frei in die Papierbahn eintaucht, was den Anwickelvorgang fördernd beeinflußt.Characterized in that by moving the wound winding core, ie the winding core with the paper roll, into a ready-to-discharge position and in that position the paper web in front of the paper roll already comes into contact with the empty winding core, 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 in the known manner without additional aids, i.e. the removal movement of the winding core provided with the paper roll is used to shift the incoming paper web, in this way in Relation to the rotary bearing receptacles that when the empty winding core is inserted, its circumferential surface largely comes into free contact with the paper web approaching the paper roll. This is achieved in that the winding core is not supported by support and auxiliary contact rollers or locking rollers, but is freely immersed in the paper web, which has a positive effect on the winding process.
Wie bereits angedeutet, lenkt dabei 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.As already indicated, 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 into the rotary bearing receptacles, wraps around the empty winding core and, due to the resulting friction, the 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 safer 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 reference to the accompanying drawing, or a device for winding or rewinding a paper web, which is shown purely schematically therein.
Auf einem Grundgestell 10 befinden sich in der Wickelstation A Drehlagerungsaufnahmen 12 zur Aufnahme von frei abstehenden Lagerenden 14 von Wickelkernen 16 (Tambour).On a
Der Wickelstation A zugeordnet ist stromab der Papierverlaufsbahn ein Schwenkarm 18, der um eine untere Schwenkachse 20 aus einer in der Zeichnung dargestellten strichpunktierten Lage in die ausgezogene Lage mittels eines hydraulischen oder pneumatischen Zylinders 22 schwenkbar ist. 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.Associated with the winding station A is a swivel arm 18 downstream of the paper path, which swivel arm can be swiveled about a lower swivel axis 20 from a dash-dotted position shown in the drawing into the extended position by means of a hydraulic or
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 levers 18, the
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
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 41 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
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
Stromab des Wickelkerns 16 in der Wickelstation A befindet sich eine Blaseinrichtung 60.A blowing
In der Zeichnung sind mehrere Betriebszustände in verschiedenen Linien dargestellt. So ist ausgezogen in der Wickelstation A der Verlauf der Papierbahn B, die Andrückrolle 56 und der Wickelkern 16 und strichpunktiert die gewickelte Papierrolle 32 dargestellt. An der Stelle B ist in ausgezogenen Linien der bewickelte Wickelkern 16 mit der Papierrolle 32 dargestellt. Diese Einheit ist in der Position D, wo eine Abgabe derselben erfolgt, gestrichelt dargestellt.Several operating states are shown in different lines in the drawing. Thus, in the winding station A, the course of the paper web B, the
Nachfolgend soll nun die Betriebsweise der Vorrichtung beschrieben werden:
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.The mode of operation of the device will now be described below:
When the winding 32 is completed in the winding station A, the
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
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
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
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 a process is both in terms of general reeling as well possible with regard to a roll over.
