Description

Die Erfindung betrifft eine Rollenschneidvorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a roll cutting device with the features of the preamble of claim 1.

Viele Materialbahnen werden in einer Breite produziert, die größer ist als diejenige, die ein späterer Verarbeiter benötigt. Beispielsweise werden Papierbahnen in Papiermaschinen hergestellt, die eine Breite von bis zu 10 m aufweisen. Drucker, die die Papierbahnen später weiterverwenden möchten, benötigen allerdings nur Breiten im Bereich von 0,4 bis 3,8 m. Aus diesem Grunde wird in einem der letzten Herstellungsschritte die Materialbahn in Teilbahnen unterteilt. Hierbei wird die Materialbahn in der Regel von einer sogenannten Jumborolle abgewickelt. Die einzelnen Teilbahnen müssen dann gleichzeitig und gemeinsam zu Teilbahnrollen aufgewikkelt werden.Many material webs are produced in one width, which is larger than that of a later processor needed. For example, paper webs in Paper machines manufactured that are up to a width 10 m. Printers the paper webs later want to continue to use, but only need widths in the range of 0.4 to 3.8 m. For this reason in one of the last manufacturing steps, the material web divided into partial webs. Here, the Material web usually from a so-called jumbo roll settled. The individual sub-lanes must then coiled up simultaneously into partial web rolls become.

Auch beim Aufwickeln von Teilbahnrollen möchte man den Aufbau einer derartigen Teilbahnrolle möglichst gut steuern können, d.h. man möchte in der Lage sein, die Wickelspannung und damit die Wickelhärte der Teilbahnrollen zu beeinflussen. In vielen Fällen möchte man außerdem erreichen, daß alle Teilbahnrollen mit der gleichen Qualität gewickelt werden, also praktisch den gleichen inneren Aufbau haben. You also want to do this when winding up partial web rolls Structure of such a web roll as good as possible can control, i.e. you want to be able to Winding tension and thus the winding hardness of the partial web rolls to influence. In many cases, you also want to achieve that all partial web rolls with the same Quality are wrapped, practically that have the same internal structure.

Zur Steuerung und Beeinflussung der Wickelqualität sind eine Reihe von Maßnahmen bekannt. Eine derartige Maßnahme besteht darin, daß eine Andruckwalze beim Wickeln mit einem vorbestimmten Druck am Umfang der entstehenden Rolle gehalten wird. Eine entsprechende Wickelvorrichtung wird von der Anmelderin unter dem Namen "Sensomat" vertrieben. Damit lassen sich gute Wickelergebnisse erzielen. Es ist allerdings aufwendig, eine derartige Sensomat-Vorrichtung für jede Wickeleinheit vorzusehen. Darüber hinaus bereitet ein derartiger Einsatz dann Schwierigkeiten, wenn die Rollenschneidvorrichtung Teilbahnen mit wechselnden Bahnbreiten erzeugen soll. Man müßte dann für jede Breite eine entsprechende Andruckwalze vorrätig halten.To control and influence the winding quality a number of measures are known. Such a measure is that a pressure roller when winding with a predetermined pressure on the circumference of the emerging Role is held. A corresponding winding device is registered by the applicant under the name "Sensomat" distributed. This allows good winding results achieve. However, it is expensive such a Sensomat device for each winding unit provided. In addition, such an application prepares then difficulties when the roll cutter Generate partial webs with changing web widths should. One would then have a corresponding one for each width Keep the pressure roller in stock.

Eine Rollenschneidvorrichtung der eingangs genannten Art ist aus FR 2 620 117 A1 bekannt. Hier ist für jede Wickelpositionsgruppe eine über die Maschinenbreite durchgehende Andruckwalze vorgesehen. Die einzelnen Wickelrollen sind jeweils auf Wickelrollenhalterungen angeordnet, die einerseits mit einer Drucksteuereinrichtung versehen sind, um die Wickelrollenhalterung mit einem gewissen Anpreßdruck gegen die Andruckwalze zu drücken. Andererseits ist ein Abstandseinstellglied vorgesehen, um die Rollen mit zunehmendem Durchmesser weiter weg von der Andruckwalze zu positionieren.A roll cutting device of the aforementioned Art is known from FR 2 620 117 A1. Here is for everyone Winding position group one across the machine width continuous pressure roller provided. The single ones Winding rolls are each on winding roll holders arranged the one hand with a pressure control device are provided around the winding roll holder with a certain contact pressure against the pressure roller to press. On the other hand, there is a distance adjuster provided to the rollers with increasing diameter position further away from the pressure roller.

Die Wickelrollen sind in jeder Wickelpositionsgruppe auf einer gemeinsamen Wickelwelle angeordnet. Die Wickelwelle ist an Schwenkarmen gehalten, die mit Hilfe eines Antriebs verschwenkt werden können. Eine Andruckrolle, die über die gesamte Länge der Maschine durchgeht, ist an einem Hebel angeordnet, der wiederum von einem Druckgeber beaufschlagt ist. Zwischen dem Hebel und einem Maschinengestell ist ein Drucksensor angeordnet.JP 61 075 760 shows a roll winding device with an automatic control for recording the contact pressure. The winding rolls are in each winding position group arranged on a common winding shaft. The winding shaft is held on swivel arms that can be pivoted using a drive.

Jede Wickelgruppe weist eine Umlenkwalze und eine schwenkbare Traverse auf, die auf Doppelhebelarmen jeweils Wickelkerne aufnimmt und in Abhängigkeit vom zunehmenden Wickeldurchmesser verstellbar ist. Ferner sind in jeder Wickelgruppe einzeln pendelnd andrückbar aufgehängte Andruckrollen vorgesehen, die mit einer vorbestimmten Kraft gegen die Wickelrollen gedrückt werden können.GB 2 137 175 A describes a roll cutting and winding machine.

DE 37 21 969 A1 beschreibt eine Vorrichtung zum Aufwikkeln einer Folienbahn, insbesondere einer Kunststoffolienbahn, zu einem Folienwickel auf einem Wickelkern. Der Wickelkern ist hierbei an Schwenkarmen angeordnet, die mit Hilfe eines Antriebs verschwenkbar werden können. Beim Verschwenken kann eine Wickelkernaufnahme, die in einem gabelförmigen Ende des Schwenkarmes geführt ist, auf einer Führungsfläche entlang bewegt werden. Ferner ist eine Kontaktwalze vorgesehen, wobei der Kontaktdruck durch den Antrieb der Schwenkarme hergestellt wird.DE 37 21 969 A1 describes a device for winding up a film web, in particular a plastic film web, to a film wrap on a winding core.

EP 0 561 128 A1 beschreibt eine Vorrichtung zum Erzeugen von Wickeln. Eine Materialbahn wird eine Wickeltrommel einem Wickelkern bzw. dem darauf sich bildenden Wickel zugeführt. Die Wickeltrommel ist verschiebbar, während der Wickel beim Wickeln ortsfest bleibt. Eine Stellvorrichtung hält die Wickeltrommel unter konstantem Druck am Wickel gegen die Kraft der Stellvorrichtung in eine Grenzlage. Beim Erreichen der Grenzlage wird die Blockierung des Wickels gelöst und die Stellvorrichtung schiebt die Wickeltrommel in eine andere Grenzlage, worauf der Wickel wieder blockiert wird. Die Bewegungsfolge wiederholt sich, bis der Wickel fertig ist.EP 0 561 128 A1 describes a device for generating of wrapping. A web of material becomes a winding drum a winding core or the one that forms on it Winding fed. The winding drum can be moved, while the winding remains stationary during winding. A Adjustment device keeps the winding drum under constant Pressure on the winding against the force of the actuator to a borderline location. When the limit is reached the blockage of the winding is released and the adjusting device pushes the winding drum into another Limit position, whereupon the wrap is blocked again. The The sequence of movements is repeated until the wrap is finished is.

Der Erfindung liegt die Aufgabe zugrunde, den Aufbau von mehreren Teilbahnrollen mit möglichst geringem Aufwand zu steuern.The invention has for its object the structure of several partial web rolls with the least possible effort to control.

Diese Aufgabe wird bei einer Rollenschneidvorrichtung der eingangs genannten Art dadurch gelöst, daß der Positionierantrieb einen Sensor aufweist, der den Durchmesser der Teilbahnrolle ermittelt und die Teilbahnrolle in Abhängigkeit vom Durchmesser so positioniert, daß der Umfang aller Teilbahnrollen in der Kontaktzone mit der Andruckwalze auf einer Geraden liegt.This task is done with a roll cutter of the type mentioned solved in that the positioning drive has a sensor that has the diameter the partial web roll is determined and the partial web roll positioned depending on the diameter so that the extent of all partial web rolls in the contact zone the pressure roller lies on a straight line.

Diese Vorgehensweise hat mehrere Vorteile. Zum einen reicht nun eine einzige Andruckwalze für alle Teilbahnrollen einer Wickelpositionsgruppe aus. Dementsprechend genügt auch eine einzige Steuerung zum Steuern der Anlagekraft. Es spielt keine Rolle mehr, welche Breiten die einzelnen Teilbahnrollen aufweisen, da die Andruckwalze in Axialrichtung keine festgelegten Grenzen mehr definiert. Es spielt im Grunde keine größere Rolle mehr, an welcher Position oder an welchen Abschnitten der Andruckwalze die jeweilige Teilbahnrolle anliegt. Man kann also wechselnde Schneidprogramme fahren, d.h. Teilbahnrollen mit unterschiedlichen und wechselnden Breiten erzeugen. Die Wickelqualität der Teilbahnrollen, die in einer Wickelpositionsgruppe gewickelt werden, ist für alle Teilbahnrollen dieser Wickelpositionsgruppe im wesentlichen gleich. Dies wird dadurch erreicht, daß jede Wickeleinheit mit Hilfe des Positionierantriebs so positioniert wird, daß sie an der Andruckwalze anliegt. Man kann also durch die Verwendung des Positionierantriebs praktisch die gleichen Ergebnisse erzielen, wie man sie bisher nur bei einer einzelnen Wickelrolle pro Andruckwalze erzielen konnte. Der Positionierantrieb positioniert die Teilbahnrolle also nicht mehr in Abhängigkeit vom Druck, sondern lediglich in Abhängigkeit von der Geometrie der Teilbahnrolle, d.h. in Abhängigkeit von dem Durchmesser der Teilbahnrolle. Man kann die Teilbahnrollen so positionieren, daß ihr Umfang in dem Bereich, in dem sie an der Andruckwalze anliegen, immer auf einer Geraden liegt. Damit ist die geometrische Anordnung festgelegt. Die Andruckwalze kann dann mit dem gewünschten Druck an den Teilbahnrollen gehalten werden, so daß die Wickelhärte und die Wickelspannung auf den gewünschten Werten gehalten werden. Hierdurch entkoppelt man die Positionierung der Teilbahnrollen vom Druck. Die Position ist nur von der Geometrie abhängig. Normalerweise haben die Teilbahnrollen bei gleichartigem Aufbau auch den gleichen Durchmesser, wenn ihnen die gleiche Länge der Materialbahn zugeführt worden ist. Es kommt in der Praxis aber immer wieder vor, daß die Papierdicke über die Bahnbreite nicht konstant ist. In einem derartigen Fall ergeben sich kleine Unterschiede von Teilbahnrolle zu Teilbahnrolle, die über den Positionierantrieb ausgeglichen werden können.This approach has several advantages. On the one hand a single pressure roller is now sufficient for all partial web rolls a winding position group. Accordingly A single control is also sufficient to control the investment power. It no longer matters which widths have the individual web rolls, since the pressure roller no longer defined limits in the axial direction Are defined. It doesn't really matter much more, at which position or in which sections the respective partial web roll lies against the pressure roller. So you can drive changing cutting programs, i.e. Partial web rolls with different and changing Generate widths. The winding quality of the partial web rolls, that are wound in a winding position group, is for all partial web rolls in this winding position group essentially the same. This is achieved that each winding unit with the help of the positioning drive is positioned so that it is on the pressure roller is applied. So you can by using of the positioning drive practically the same results achieve, as you have only done with a single Could achieve winding roll per pinch roller. The positioning drive positions the partial web roll So no longer depending on the pressure, but only dependent on on the geometry of the partial web roll, i.e. dependent on on the diameter of the partial web roll. you can position the partial web rolls so that their circumference in the area where they are in contact with the pressure roller, always lies on a straight line. So that's it geometric arrangement set. The pressure roller can then with the desired pressure on the partial web rolls are held so that the winding hardness and Winding tension can be kept at the desired values. This decouples the positioning of the Partial web rolls from printing. The position is only from that Geometry dependent. Usually the partial web rolls with the same structure also the same Diameter if they have the same length of material web has been supplied. It happens in practice though again and again that the paper thickness over the web width is not constant. In such a case small differences from partial web roll to Partial web roll, which is balanced by the positioning drive can be.

Vorzugsweise ist die Andruckwalze in einem Schlitten angeordnet, der senkrecht zur Achse der Teilbahnrollen bewegbar ist. Mit zunehmendem Durchmesser der Teilbahnrollen kann dann der Schlitten wegbewegt werden, so daß die Funktion der Andruckwalze über den gesamten Wickelvorgang erhalten bleiben kann. Innerhalb des Schlittens kann die Andruckwalze noch über eine Drucksteuerung bewegt werden, die den Anpreßdruck einstellt.The pressure roller is preferably in a carriage arranged perpendicular to the axis of the partial web rolls is movable. With increasing diameter of the partial web rolls the carriage can then be moved away so that the function of the pressure roller over the entire winding process can be preserved. Inside the sled the pressure roller can still be moved using a pressure control that sets the contact pressure.

Hierbei ist besonders bevorzugt, daß der Schlitten linear in Radialrichtung der Teilbahnrollen bewegbar ist. Damit ändert sich mit zunehmendem Durchmesser der Teilbahnrollen die Anlagegeometrie der Andruckwalze an den Teilbahnrollen nicht, was die Steuerung weiter vereinfacht.It is particularly preferred that the carriage is linear is movable in the radial direction of the partial web rolls. This changes with increasing diameter of the partial web rolls the contact geometry of the pressure roller to the Partial web rolls do not, which further simplifies control.

Mit Vorteil weist der Schlitten einen Antrieb auf, der in Abhängigkeit vom Durchmesser der Teilbahnrollen gesteuert ist. Der Schlitten wird also mit zunehmendem Durchmesser der Teilbahnrollen verfahren, und zwar immer so, daß die Andruckwalzen dem Durchmesserzuwachs folgen kann. Die Steuerung der Kraft beziehungsweise des Drucks, mit dem die Andruckwalze an den Teilbahnrollen anliegt, ist von der linearen Bewegung des Schlittens entkoppelt.The slide advantageously has a drive which controlled depending on the diameter of the partial web rolls is. So the sled gets more and more Always move the diameter of the partial web rolls so that the pressure rollers the diameter increase can follow. The control of the force respectively the pressure with which the pressure roller on the partial web rolls is from the linear movement of the Sled decoupled.

Vorteilhafterweise verbleibt jede Wickeleinheit beim Wickeln im wesentlichen ortsfest. Hierdurch wird die Bewegungssteuerung vereinfacht. Der Positionierantrieb muß lediglich dafür sorgen, daß alle Teilbahnrollen mit ihrem Umfang in dem Bereich, in dem sie an der Andruckrolle anliegen, auf einer Gerade liegen. Überlagerte Bewegungen, wie sie etwa durch einen Durchmesserzuwachs der Teilbahnrollen erforderlich wären, muß der Positionierantrieb nicht berücksichtigen.Each winding unit advantageously remains with the Winding essentially stationary. This will make the Movement control simplified. The positioning drive only has to ensure that all partial web roles with their scope in the area where they are on the pinch roller lie on a straight line. Superimposed Movements such as those caused by an increase in diameter of the partial web rolls would be required, the positioning drive disregard.

Vorzugsweise weist jede Wickeleinheit ein Paar von Schwenkarmen auf, die Lagerdorne für Rollenkerne aufweisen, wobei die Schwenkarme aus einer Wickelstellung in eine Ablagestellung verschwenkbar sind. Man nutzt die Schwenkarme dann für zwei Aufgaben aus. Zum Wickeln werden die Schwenkarme in ihre Wickelstellung verbracht. Dort kann der Positionierantrieb in Tätigkeit gesetzt werden, falls dies notwendig ist. Die Schwenkarme werden gleichzeitig aber auch dazu ausgenutzt, die fertigen Teilbahnrollen aus der Wickelstellung herauszubewegen und in eine Ablagestellung zu bringen, wo sie aus der Rollenschneidvorrichtung, genauer gesagt, aus der Wickelstation, entnommen werden können.Each winding unit preferably has a pair of Swivel arms with bearing mandrels for roll cores, the swivel arms from a winding position are pivotable into a storage position. You use the swivel arms are then used for two tasks. For wrapping the swivel arms are brought into their winding position. The positioning drive can be active there be set if necessary. The swivel arms but are also used at the same time, the to move finished partial web rolls out of the winding position and put it in a storage position where it from the roll cutter, more precisely, from the winding station, can be removed.

Vorzugsweise stehen die Schwenkarme in der Wickelstellung im wesentlichen senkrecht. In der Wickelstellung nimmt das Gewicht der Teilbahnrollen mit zunehmendem Durchmesser zu. Wenn die Schwenkarme senkrecht stehen, können sie das Gewicht aufnehmen, ohne daß man Halteelemente zusätzlich belasten muß.The swivel arms are preferably in the winding position essentially vertical. In the winding position the weight of the partial web rolls increases with increasing Diameter too. If the swivel arms are vertical, they can take up the weight without holding elements must also burden.

Hierbei ist besonders bevorzugt, daß die Schwenkarme einzeln parallel zur Axialrichtung der Teilbahnrollen verfahrbar sind. Damit lassen sich durch eine einfache Veränderung der Position der Schwenkarme unterschiedliche Breiten der Teilbahnrollen einstellen.It is particularly preferred that the swivel arms individually parallel to the axial direction of the partial web rolls are movable. This can be done by a simple Change the position of the swivel arms different Set the widths of the partial web rolls.

Mit Vorteil ist mindestens ein Lagerdorn jedes Paares von Schwenkarmen als Spanndorn ausgebildet und angetrieben. Die Teilbahnrollen werden dann über einen Zentrumsantrieb angetrieben. Hierzu ist es notwendig, daß von den Lagerdornen mindestens einer eine Antriebsleistung auf den Rollenkern übertragen kann. Dies erfolgt zweckmäßigerweise durch eine Ausbildung als Spanndorn.At least one bearing pin of each pair is advantageous formed and driven by swivel arms as a mandrel. The partial web rolls are then driven by a center drive driven. For this it is necessary that at least one of the bearing arbors has a drive power can be transferred to the roll core. this happens expediently by training as a mandrel.

Mit Vorteil erfolgt die Materialbahnzufuhr in die Wikkelpostionsgruppe von oben. Dies erleichtert die Zuführung. Die Teilbahnrollen können dann in Halte- oder Schwenkarmen aufgenommen sein, die in Schwerkraftrichtung unten abgestützt sind. Auch kann die Andruckwalze in ihrem Schlitten auf einem Fundament oder einem Maschinengestell abgestützt sein, ohne daß sie bei ihrer Bewegung mit der zugeführten Materialbahn in Konflikt gerät. The material web is advantageously fed into the winding post group from above. This makes feeding easier. The partial web rolls can then be held or Swivel arms can be added in the direction of gravity are supported at the bottom. The pressure roller can also in their sled on a foundation or machine frame be supported without her Movement in conflict with the material web being fed device.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung beschrieben. Hierin zeigen:

Fig. 1
eine schematische Seitenansicht einer Rollenschneidvorrichtung und
Fig. 2
eine schematische Draufsicht auf eine Wickelpositionsgruppe.
The invention is described below with reference to a preferred embodiment in conjunction with the drawing. Show here:
Fig. 1
is a schematic side view of a roll cutting device and
Fig. 2
is a schematic plan view of a winding position group.

Eine Rollenschneidvorrichtung 1 weist einen Bahnzuführabschnitt 2 für eine Materialbahn 3 auf, die mit Hilfe eines Längsschneiders 4 in mehrere Teilbahnen geschnitten werden soll. Die Teilbahnen werden dann zu Teilbahnrollen 5, 6 aufgewickelt, die in zwei Wickelpositionsgruppen 7, 8 so angeordnet sind, daß die Teilbahnrollen 5, 6 benachbarter Teilbahnen auf Lücke zueinander angeordnet sind.A roll cutting device 1 has a web feed section 2 for a material web 3, which with the help a slitter 4 cut into several partial webs shall be. The partial webs then become partial web rolls 5, 6 wound up in two winding position groups 7, 8 are arranged so that the partial web rolls 5, 6 of adjacent partial webs to each other are arranged.

Die Teilbahnen werden in einer Weichenanordnung 9 also abwechselnd nach links und nach rechts transportiert (bezogen auf die Darstellung in Fig. 1), beispielsweise mit Hilfe von Blasrohren 10, 11, die einzeln steuerbare Düsen aufweisen.The partial tracks are in a switch arrangement 9 alternately transported to the left and to the right (based on the representation in Fig. 1), for example with the help of blowpipes 10, 11, the individually controllable Have nozzles.

Die Teilbahnen 18, 19 werden dann über Umlenkrollen 12, 13, Leitwalzen 14, 15 und Umlenkrollen 16, 17 zu den Teilbahnrollen 5, 6 geführt. In jeder Wickelpositionsgruppe 7, 8 ist eine Andruckwalze 20, 21 vorgesehen, die mit den Teilbahnrollen 5, 6 jeweils einen Nip bildet, in den die Teilbahnen 18, 19 eingeführt werden.The partial webs 18, 19 are then over deflection rollers 12, 13, guide rollers 14, 15 and guide rollers 16, 17 to the Partial web rollers 5, 6 out. In each winding position group 7, 8 a pressure roller 20, 21 is provided, which forms a nip with the partial web rolls 5, 6, into which the partial webs 18, 19 are introduced.

Die Teilbahnrollen 5, 6 sind auf Schwenkarmen 22, 23 gelagert. Die Schwenkarme sind mit Hilfe eines schematisch dargestellten Antriebs 24, der beispielsweise als Kolben-Zylinder-Einheit ausgebildet sein kann, aus einer im wesentlichen senkrechten Stellung, wie sie in Fig. 1 dargestellt ist, um etwa 90° verschwenkbar, so daß eine fertig gewickelte Teilbahnrolle 5, 6 auf dem Fußboden 25 abgelegt werden kann. Die Teilbahnrolle 5, 6 legt dann einen Weg zurück, wie er durch den gestrichelt dargestellten Doppelpfeil 26 angedeutet ist.The partial web rolls 5, 6 are on swivel arms 22, 23 stored. The swivel arms are schematic using a shown drive 24, for example as Piston-cylinder unit can be formed from one essentially vertical position, as in Fig. 1 is shown, pivotable about 90 °, so that a fully wound partial web roll 5, 6 on the Floor 25 can be stored. The partial web roll 5, 6 then travels a path as shown by the dashed line shown double arrow 26 is indicated.

Jede Teilbahnrolle weist eine Wickelhülse 27 auf, in die ein Spanndorn 28, 29 an jedem Haltearm 22, 23 eingreift. Die Spanndorne 28, 29 können beispielsweise pneumatisch betätigt sein. Sie sind durch schematisch dargestellte Antriebe 30, 31 antreibbar, so daß die Teilbahnrollen 5, 6 über ihre Wickelhülse 27, also über den Rollenkern, angetrieben werden. Es handelt sich mit anderen Worten also um einen Zentrumsantrieb.Each partial web roll has a winding tube 27, in which engages a mandrel 28, 29 on each holding arm 22, 23. The mandrels 28, 29 can for example be pneumatically operated. They are through schematically shown drives 30, 31 driven so that the Partial web rolls 5, 6 over their winding tube 27, that is over the roller core. It's about in other words, a center drive.

Aus Gründen der Übersichtlichkeit ist in Fig. 2 mit durchgezogenen Linien die Position der Teilbahnrollen 5 dargestellt, in der sie auf den Fußboden 25 abgelegt sind. Mit gestrichelten Linien ist die Wickelposition der Teilbahnrollen 5 dargestellt.For reasons of clarity, in Fig. 2 with solid lines indicate the position of the partial web rolls 5 shown in which it is placed on the floor 25 are. With dashed lines is the winding position the partial web rolls 5 shown.

Die Andruckwalzen 20, 21 sind jeweils auf Schlitten 32, 33 angeordnet, die in Richtung der Doppelpfeile 34, 35 radial zu den Teilbahnrollen 5, 6 verschiebbar sind. Sie sind hierzu auf einem Maschinengestell 36 verschiebbar abgestützt. An den Schlitten 32, 33 sind auch noch die Leitwalzen 14, 15 und die Umlenkwalzen 16, 17 angeordnet. Die Andruckwalzen 20, 21 werden daher beim Wickeln der Teilbahnrollen 5, 6 von der gestrichelt dargestellten Position, in der sie praktisch an der Wickelhülse 27 anliegen, in die in durchgezogenen Linien dargestellte Position verfahren. Hierbei werden sie unter der Wirkung eines nicht näher dargestellten Anstellantriebs, der am Schlitten 32,33 angeordnet ist, mit einem gewissen Druck am Umfang der Teilbahnrollen 5, 6 gehalten.The pressure rollers 20, 21 are each on slides 32, 33 arranged in the direction of the double arrows 34, 35 are radially displaceable to the partial web rolls 5, 6. For this purpose, they can be moved on a machine frame 36 supported. On the sled 32, 33 are also still the guide rollers 14, 15 and the deflection rollers 16, 17th arranged. The pressure rollers 20, 21 are therefore at Wind the partial web rolls 5, 6 from the dashed shown position in which they are practically at the Wrap sleeve 27 abut in the solid lines Move position shown. Here they will under the action of a positioning drive, not shown, which is arranged on the slide 32, 33 with a certain pressure on the circumference of the partial web rolls 5, 6 held.

Die Steuerung der Bewegung der Schlitten 32, 33 erfolgt mit Hilfe von Durchmessersensoren 37, 38, die fortlaufend den Durchmesser der Teilbahnrollen ermitteln. Hierbei sind derartige Sensoren für jede Wickeleinheit vorgesehen, d.h. es werden tatsächlich die Durchmesser aller Teilbahnrollen 5, 6 ermittelt. Die Durchmessersensoren können beispielsweise als Entfernungsmesser ausgebildet sein, die die Entfernung von ihrer Position zum Umfang der Teilbahnrollen 5, 6 ermitteln.The movement of the slides 32, 33 is controlled with the help of diameter sensors 37, 38, which are continuous determine the diameter of the partial web rolls. Here are such sensors for each winding unit provided, i.e. it will actually be the diameter of all web rolls 5, 6 determined. The diameter sensors can be used, for example, as a rangefinder be trained the distance from their position determine the extent of the partial web rolls 5, 6.

Die Durchmessersensoren 37, 38 liefern Informationen für zwei Aufgaben. Zum einen wird die Steuerung der Bewegung der Schlitten 32, 33 und damit auch der Bewegung 20, 21 mit Hilfe der Durchmesserinformation vorgenommen. Je stärker der Durchmesser ansteigt, desto weiter muß der Schlitten 32, 33 verfahren werden. Hierfür werden die Durchmesserwerte aller Teilbahnrollen 5, 5', 5" beispielsweise gemittelt. Es ist aber auch möglich, den Durchmesser der größten oder der kleinsten oder auch einer der mittleren Teilbahnrollen zu verwenden.The diameter sensors 37, 38 provide information for two tasks. Firstly, the control of the movement the carriage 32, 33 and thus also the movement 20, 21 made with the aid of the diameter information. The more the diameter increases, the further the carriage 32, 33 must be moved. For that be the diameter values of all partial web rolls 5, 5 ', 5 " for example averaged. But it is also possible that Diameter of the largest or the smallest or also to use one of the middle web rolls.

Der Durchmesser jeder einzelnen Teilbahnrolle 5, 5', 5" (Fig. 2) wird darüber hinaus noch für eine weitere Aufgabe benötigt. Jede Wickeleinheit 39, 39', 39" ist nämlich noch mit einem Positionierantrieb versehen, der den Umfang der entsprechenden Teilbahnrolle 5, 5', 5" an der Andruckwalze 20 hält. Genauer gesagt, wird jede Teilbahnrolle 5, 5', 5" so positioniert, daß im Bereich des Kontaktes der Teilbahnrollen mit der Andruckwalze 20 sämtliche Teilbahnrollen auf einer Geraden liegen. Wenn nun die Andruckwalze 20 mit der entsprechenden Andruckkraft beaufschlagt wird, dann liegt sie an allen Teilbahnrollen 5, 5', 5" mit der gleichen Kraft an, da alle Teilbahnrollen hier die gleiche Position eingenommen haben.The diameter of each individual web roll 5, 5 ', 5 " (Fig. 2) is also used for another task needed. Each winding unit 39, 39 ', 39 "is namely provided with a positioning drive that the scope of the corresponding partial web roll 5, 5 ', 5 " holds on the pressure roller 20. More specifically, everyone will Partial web roll 5, 5 ', 5 "positioned so that in the area the contact of the partial web rolls with the pressure roller 20 all partial web rolls lie on a straight line. If now the pressure roller 20 with the corresponding pressure force is applied, then it is up to everyone Partial web rolls 5, 5 ', 5 "with the same force, because all partial web reels are in the same position here to have.

Der Positionierantrieb kann beispielsweise durch den Antrieb 24 gebildet sein, der dann, wenn der Durchmesser der Teilbahnrolle 5, 5', 5" größer oder kleiner ist als der einer anderen Teilbahnrolle 5, 5', 5" den Schwenkarm 22 näher zur Andruckwalze 20 hin- oder weiter wegschwenkt.The positioning drive can, for example, by the Drive 24 may be formed when the diameter the partial web roll 5, 5 ', 5 "is larger or smaller than that of another part web roll 5, 5 ', 5 " Swivel arm 22 closer to or closer to the pressure roller 20 pivots away.

Im übrigen bleiben aber die Schwenkarme 22, 23 beim Wickeln ortsfest.Otherwise, the swivel arms 22, 23 remain with Wrap stationary.

Unterschiedliche Durchmesser der Teilbahnrollen 5, 5', 5" können sich beispielsweise ergeben, wenn die Papierbahn über ihre Breite keine konstante Dicke aufweist und sich deswegen Teilbahnen mit unterschiedlicher Dikke ergeben, die Teilbahnrollen mit unterschiedlichen Durchmessern erzeugen.Different diameters of the partial web rolls 5, 5 ', 5 "can arise, for example, if the paper web does not have a constant thickness over its width and therefore partial webs with different thickness result, the partial web rolls with different Generate diameters.

Wie in Fig. 2 schematisch angedeutet ist, können die einzelnen Schwenkarme in Richtung der Doppelpfeile 40 einzeln verfahren werden. Hierdurch lassen sich unterschiedliche Teilbahnrollenbreiten und unterschiedliche Abstände einstellen, so daß unterschiedliche Schneidmuster gefahren werden können.As indicated schematically in Fig. 2, the individual swivel arms in the direction of the double arrows 40 can be moved individually. This allows different Partial web widths and different Set distances so that different cutting patterns can be driven.
