Wickelmaschine zum Aufwickeln von Papier- oder KartonbahnenWinding machine for winding paper or cardboard webs
Technisches GebietTechnical field
Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln von Papier- oder Kartonbahnen gemäß dem Oberbegriff des Patentanspruchs 1 .The invention relates to a winding machine for winding paper or cardboard webs according to the preamble of claim 1.
Zur Herstellung von Wickelrollen aus durch Längsschneiden in Einzelbahnen unterteilte Papier- oder Kartonbahnen sind Wickelmaschinen bekannt, bei denen die Wickelrollen beim Aufwickeln umfänglich an einer oder zwei angetriebenen Stütz- oder Tragwalzen anliegen. Bei diesen als Umfangswickler bezeichneten Wickeimaschinen werden die Wickelrollen von den angetriebenen Stütz- oder Tragwalzen beim Aufwickeln gedreht. Die DE 39 33 861 -A1 beschreibt eine gattungsgemäße Stützwalzen-Rollmaschine, bei denen die Wickelrollen wechselweise beidseits der Scheitellinie einer zentralen Stützwalze angeordnet sind, an der sie beim Aufwickeln anliegen. Seitlich in die Hülse einer jeden Wickelrolle einfahrbare, frei drehbare Führungsköpfe tragen ganz oder teilweise das Roliengewicht.For the production of winding rolls from paper or cardboard webs divided by longitudinal cutting into individual webs, winding machines are known in which the winding rolls lie circumferentially against one or two driven support or support rollers during winding. In these winding machines, which are referred to as circumferential winders, the winding rollers are rotated by the driven support or support rollers during winding. DE 39 33 861-A1 describes a generic backup roller rolling machine in which the winding rollers are alternately arranged on both sides of the apex line of a central backup roller, on which they rest during winding. Freely rotatable guide heads that can be inserted laterally into the sleeve of each winding roll bear all or part of the roll weight.
Stand der TechnikState of the art
Aus der DE 40 12 979-A1 ist es bekannt, jeden der Führungsköpfe mit einem Drehantrieb zu verbinden, um die Zugspannung jeder Wickelrolle beim Aufwickeln individuell regeln zu können. Diese zusätzlichen Zentrumsantriebe sind bei der Verarbeitung von sehr breiten (8 m und mehr) Papierbahnen mit Wickelmaschinen, die viele Wickeistationen (10 und mehr) aufweisen, sehr aufwendig, und darüber hinaus wird die minimale Breite einer Wickelrolle vergrößert, da die angetriebenen Führungsköpfe nicht zum Einspannen neuer Hülsen und zum Entladen der Wickelrollen in den Wickelböcken versenkt werden können.From DE 40 12 979-A1 it is known to connect each of the guide heads to a rotary drive in order to tension each winding roll during winding to be able to regulate individually. These additional center drives are very complex when processing very wide (8 m and more) paper webs with winding machines, which have many winding stations (10 and more), and in addition the minimum width of a winding roll is increased because the driven guide heads are not used for Clamping new tubes and for unloading the winding rolls can be sunk in the winding trestles.
In der Praxis hat es sich gezeigt, daß bei Papieren mit niedrigem Flächenge¬ wicht, insbesondere bei Zeitungsdruckpapieren, in den beiden äußeren Wickel¬ rollen (Randrollen) unter bestimmten Umständen unerwünschte Kreppfalten als Roilenfehler auftreten können, sofern sie mit Wickelmaschinen gewickelt werden, bei denen die Wickelrolien ausschließlich von der angetriebenen Stütz¬ oder Tragwalze beim Aufwickeln gedreht werden.In practice, it has been found that, in certain circumstances, undesired crepe folds can occur as roll defects in papers with a low basis weight, in particular in newsprint papers, in the two outer winding rolls (edge rolls), provided that they are wound with winding machines in which the winding sheets are rotated exclusively by the driven support or support roller during winding.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Wickelmaschine so zu verbessern, daß mit möglichst geringem konstruktiven Aufwand die Randrollen mit verbesserter Qualität gewickelt werden können.The invention has for its object to improve a generic winding machine so that the edge rolls can be wound with improved quality with the least possible design effort.
Diese Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of patent claim 1.
Es hat sich gezeigt, daß bei Zeitungsdruckpapieren die Papierbahn keine homogene Länge aufweist, sondern an den Bahnrändern länger ist. Dadurch ist bei den beiden Randrollen die Bahnzugspannung vor dem Aufwickeln geringer als bei den mittleren Rollen, was zum Erreichen einer gleichmäßigen Wickelhärte eines Wickelrollensatzes durch eine erhöhte Linienlast an der Anliegelinie der Randrollen zur Stütz- oder Tragwaize kompensiert werden muß. Das geänderte Verhältnis zwischen Bahnzugspannung und Linienlast bei den Randrollen erhöht jedoch die Anfälligkeit für das Auftreten von Kreppfalten.It has been shown that in newsprint paper, the paper web is not homogeneous in length, but is longer at the edges of the web. As a result, the web tension before winding is lower for the two edge rolls than for the middle rolls, which has to be compensated for in order to achieve a uniform winding hardness of a set of winding rolls by means of an increased line load on the line of contact of the edge rolls for supporting or carrying rolls. However, the changed relationship between web tension and line load for the edge rolls increases the susceptibility to the occurrence of crepe folds.
Nach der Erfindung läßt sich die Bahnzugspannung der Randrollen unabhängig von den übrigen Wickelrollen durch ein gleichmäßiges Drehmoment der Umfangsantriebe erhöhen, um die Inhomogenitäten der Bahn auszugleichen. Am Rand eingesetzte Zentrumsantriebe wären konstruktiv aufwendiger, da sie nicht mit gleichmäßigem Drehmoment arbeiten könnten und zudem eine größere Anzahl erforderlich wäre, um alle möglichen, bei verschiedenen Formatkombinationen die Randrollen aufwickelnden Wickelstationen damit auszurüsten.According to the invention, the web tension of the edge rolls can be increased independently of the other winding rolls by a uniform torque of the peripheral drives in order to compensate for the inhomogeneities of the web. At the Center drives used on the edge would be more complex in terms of design, since they would not be able to work with a uniform torque and, in addition, a larger number would be required in order to equip them with all possible winding stations that wind up the edge rolls in different format combinations.
Die Unteransprüche enthalten bevorzugte, da besonders vorteilhafte Ausgestaltungen einer erfindungsgemäßen Wickelmaschine.The subclaims contain preferred, since particularly advantageous, configurations of a winding machine according to the invention.
Während sich die quer zur Bahnlaufrichtung verfahrbaren Umfangsantriebe nach Anspruch 2 auf verschiedene Formatbreiten einstellen lassen, werden durch die elastische und mit Nuten versehene Oberfläche der Walze oder des Bandes nach Anspruch 3 schädliche Einflüsse beim Andrücken und Probleme durch eingewickelte Luft vermieden.While the circumferential drives movable transversely to the direction of web travel can be set to different format widths according to claim 2, the elastic and grooved surface of the roller or belt according to claim 3 avoids harmful influences during pressing and problems caused by wrapped air.
Eine Walze mit integriertem Trommelantrieb nach Anspruch 4 ist konstruktiv besonders vorteilhaft und platzsparend. Bei der Ausgestaltung nach Anspruch 5 werden von den vorhandenen Druckwalzen, die zu Beginn einer Wicklung die Linienlast erhöhen, die beiden äußeren vorteilhaft zugleich für die Umfangsantriebe an den Randrollen verwendet.A roller with an integrated drum drive according to claim 4 is structurally particularly advantageous and space-saving. In the embodiment according to claim 5 of the existing pressure rollers, which increase the line load at the beginning of a winding, the two outer ones are advantageously used at the same time for the peripheral drives on the edge rollers.
Beim Aufwickeln entlang zweier Wickellinien sind nach Anspruch 6 an den beiden Randseiten jeder Wickellinie jeweils ein zusätzlicher Umfangsantrieb, also insgesamt vier Umfangsantriebe, angeordnet, um eine unterschiedliche Anzahl von Wickelrollen mit unterschiedlichen Formatbreiten frei auf beide Wickellinien verteilen zu können. Patentanspruch 7 beansprucht eine Wickelmaschine zum Aufwickeln von breiten Papierbahnen, bei der die Breite der angetriebenen Walzen oder Bänder der erforderlichen Erhöhung der Zugspannung an den Rändern angepaßt ist.When winding along two winding lines, an additional peripheral drive, that is a total of four peripheral drives, are arranged on the two edge sides of each winding line, in order to be able to distribute a different number of winding rolls with different format widths freely on both winding lines. Claim 7 claims a winding machine for winding wide paper webs, in which the width of the driven rollers or belts is adapted to the required increase in tension at the edges.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Die mehr als 5 Meter breite Papierbahn 1 wird von einer in einer Abrollung aufgehängten Vorratsrolle 2 abgezogen, durch Längsschneiden in Einzelbahnen aufgeteilt und anschließend zu Wickelrollen 3 aufgewickelt. Die Bahn 1 wird mittels Leitrollen 4 von der Abrollung bis in den Bereich unterhalb einer ebenfalls mehr als 5 m breiten Stützwalze 5 geführt, wo eine Längsschneideeinrichtung 6, bestehend aus mehreren Kreismesserpaaren, angeordnet ist, die die Bahn 1 in mehrere Einzelbahnen aufteilt, die dann wechselweise den beiden Wickellinien zugeführt werden.The paper web 1, which is more than 5 meters wide, is drawn off from a supply roll 2 suspended in a roll, divided into individual webs by slitting and then wound up into winding rolls 3. The web 1 is guided by means of guide rollers 4 from the unwind to the area below a support roller 5, also more than 5 m wide, where a longitudinal cutting device 6, consisting of several pairs of circular knives, is arranged, which divides the web 1 into several individual webs, which then alternately fed to the two winding lines.
Die Wickelrollen 3 liegen während des Aufwickeins wechselweise beidseits der Scheitellinie an der angetriebenen Stützwalze 5. Sie werden dabei jeweils von zwei beidseits in die Wickelhüisen eingefahrenen, frei drehbaren Führungsköpfen 7 gehalten. Die Führungsköpfe 7 sind an quer zur Bahnlaufrichtung verfahrbaren Wickelböcken 8 gelagert, wobei jeweils zwei Wickelböcke 8 eine Wickeistation für eine Wickelrolle 3 bilden. Es können 10 und mehr Wickelstationen vorhanden sein. Die Führungsköpfe 5 sind, um ihre Position dem wachsenden Wickelrollendurchmesser anpassen zu können, radial zur Stützwalze 5 verfahrbar an den Wickelböcken 8 befestigt. An der Einlauf- und Auslaufseite der Maschine ist außerhalb des Wickelbereichs jeweils eine heb- und senkbare Traverse 9, 10 angeordnet, die sich über die gesamte Arbeitsbreite erstreckt. Auf den Traversen 9, 10 sind Schlitten 1 1 , 12 quer zur Bahnlaufrichtung verfahrbar gelagert, an denen Schwenkarme 13, 14 mit jeweils einem Druckrollenpaar 15 befestigt sind. Die um eine Achse parallel zur Stützwalzenachse frei drehbaren Druckrollenpaare 15 werden zu Beginn einer Wicklung gegen den Umfang der Wickelrollen 3 gedrückt, um die Linienlast an der Anliegelinie zwischen den Wickelrollen 3 und der Stützwalze 5 zu vergrößern, wenn das Eigengewicht der Wickelrollen 3 noch nicht ausreicht. Bei der vorstehend beschriebenen Ausführungsform übernehmen die Führungsköpfe 5 bei zunehmendem Wickelrollendurchmesser einen Teil des Roliengewichts, um die Linienlast an der Anliegelinie zur Stützwalze 5 auf einem gewünscht niedrigen Wert zu halten. Anstelle einer Stützwalze 5 können auch zwei Tragwalzen eingesetzt werden, die ein Walzenbett bilden, in dem die Wickelrollen 3 beim Aufwickeln aufliegen.The winding rollers 3 lie alternately on both sides of the apex line on the driven support roller 5. They are each held by two freely rotatable guide heads 7 which are inserted into the winding sleeves on both sides. The guide heads 7 are mounted on winding blocks 8 which can be moved transversely to the web running direction, two winding blocks 8 each forming a winding station for a winding roll 3. There can be 10 or more winding stations. In order to be able to adapt their position to the growing winding roll diameter, the guide heads 5 are fastened to the winding stands 8 such that they can be moved radially to the support roller 5. On the inlet and outlet side of the machine, a lifting and lowering cross-piece 9, 10 is arranged outside the winding area, which extends over the entire working width. On the crossbeams 9, 10, carriages 11, 12 are mounted such that they can be moved transversely to the direction of web travel, on which swivel arms 13, 14 are each fastened with a pair of pressure rollers 15. The pressure roller pairs 15, which can be freely rotated about an axis parallel to the support roller axis, are pressed against the circumference of the winding rollers 3 at the beginning of a winding in order to increase the line load on the contact line between the winding rollers 3 and the support roller 5 when the dead weight of the winding rollers 3 is not yet sufficient . In the embodiment described above, the guide heads 5 take over part of the roll weight as the winding roll diameter increases, in order to keep the line load on the contact line to the support roll 5 at a desired low value. Instead of a support roller 5, two support rollers can also be used, which form a roller bed in which the winding rollers 3 rest during winding.
Fig. 2 zeigt einen der beiden Randbereiche an einer der Längsseite der Wickelmaschine, in dem die äußere Wickelrolle (Randrolle 16) gewickelt wird. Es wird in zwei Wickellinien gewickelt (in Fig. 1 und 2 links und rechts der angetriebenen Stütz walze 5), wobei in der linken Wickellinie das An wickeln einer neu eingelegten Wickelhülse gezeigt ist. An den beiden Längsseiten jeder Wickeliinie ist jeweils ein zusätzlicher Umfangsantrieb 17, 18 für die Randrollen 16 angeordnet, es sind somit ingesamt vier Umfangsantriebe vorhanden. Die Umfangsantriebe 17, 18 bestehen im beschriebenen Ausführungsbeispiel aus einer in etwa radial zur Stützwalze 5 elastisch gegen die jeweilige Randrolle 16 andrückbaren, mit einem eigenen Drehantrieb versehenen Walze 19, 20, deren Drehachse parallel zur Achse der Stützwalze 5 verläuft. Als Drehantrieb ist in die Walzen 19, 20 ein sogenannter elektrischer Trommelantrieb integriert, alternativ können die Walzen 19, 20 von anderen Motoren (Elektro-, Hydraulik- oder Pneumatikmotoren) über ein Getriebe (z. B. einen Riementrieb) angetrieben werden. Die Oberfläche der Walzen 19, 20 sind elastisch und weisen Nuten auf, um ein unerwünschtes Einwickeln von Luft zu verhindern. Sie sind am freien Ende von Schwenkarmen 21 , 22 gelagert, die jeweils an einem quer verfahrbaren Schlitten 23, 24 angelenkt sind. Die Schlitten 23, 24 sind quer zur Bahnlaufrichtung verfahrbar auf den Druckwalzentraversen 9, 10 gelagert, um die Umfangsantriebe 17, 18 den jeweiligen Positionen der Randroilen 16 anpassen und bei Nichtbenutzung außerhalb des Bahnbereichs parken zu können.Fig. 2 shows one of the two edge areas on one of the long sides of the winding machine, in which the outer winding roller (edge roller 16) is wound. It is wound in two winding lines (in Fig. 1 and 2 left and right of the driven support roller 5), with the winding on the left of a newly inserted winding tube is shown. On the two long sides of each winding line, an additional peripheral drive 17, 18 is arranged for the edge rollers 16, so there are a total of four peripheral drives. The circumferential drives 17, 18 in the exemplary embodiment described consist of a roller 19, 20 which can be pressed elastically against the respective edge roller 16 and is provided with its own rotary drive, approximately radially to the support roller 5 and whose axis of rotation runs parallel to the axis of the support roller 5. A so-called electric drum drive is integrated as a rotary drive in the rollers 19, 20; alternatively, the rollers 19, 20 can be driven by other motors (electric, hydraulic or pneumatic motors) via a gear (e.g. a belt drive). The surface of the rollers 19, 20 are elastic and have grooves to prevent unwanted wrapping of air. They are mounted on the free end of swivel arms 21, 22, which are each articulated on a cross-movable carriage 23, 24. The carriages 23, 24 are mounted such that they can be moved transversely to the web running direction on the pressure roller traverses 9, 10 in order to adapt the peripheral drives 17, 18 to the respective positions of the edge rollers 16 and to be able to park outside the web area when not in use.
Alternativ zu den angetriebenen Walzen 19, 20 können auch angetriebene Bänder eingesetzt werden, deren Drehachsen dann ebenfalls parallel zur Achse der Stütz walze 5 verlaufen. Nach einer anderen Ausführungsform der Erfindung werden von den in Fig. 1 gezeigten Druckwalzenpaaren 14 jeweils die beiden äußeren, gegen die Randrollen 16 andrückbaren mit einem abschaltbaren Drehantrieb verbunden und dienen so als zusätzlicher Umfangsantrieb für die Randrollen 16.As an alternative to the driven rollers 19, 20, driven belts can also be used, the axes of rotation of which then also run parallel to the axis of the support roller 5. According to another embodiment of the invention, each of the two outer pressure roller pairs 14 shown in FIG. 1 are connected to a rotary drive that can be switched off and can be pressed against the edge rollers 16 and thus serve as an additional peripheral drive for the edge rollers 16.
Die jeweils quer zur Bahniaufrichtung gemessene Breite der angetriebenen Walzen 19, 20 oder Bänder beträgt zwischen 300 mm und 700 mm, vorzugsweise zwischen 400 mm und 500 mm. Der Durchmesser der Walzen 19, 20 beträgt ca. 200 mm.The width of the driven rollers 19, 20 or belts measured transversely to the web direction is between 300 mm and 700 mm, preferably between 400 mm and 500 mm. The diameter of the rollers 19, 20 is approximately 200 mm.
Beim Aufwickeln der Wickelrollen 3, 1 6 werden die Walzen 19, 20 mit einem vorgegebenen Drehmoment angetrieben, um die Bahnzugspannung zum Ausgleich der größeren Bahnlänge in den Randbereichen der Bahn 1 beim Aufwickeln der Randrollen 16 zu erhöhen. When winding the winding rolls 3, 1 6, the rollers 19, 20 are driven with a predetermined torque in order to increase the web tension to compensate for the greater length of the web in the edge regions of the web 1 when winding up the edge rolls 16.
