Abstract

The invention relates to a winder for rolling up a running web of paper, film or the like, comprising a carrier roll (1) having the same width as the web, a spool (2) on which the web is wound up into a roll, a first pair of swivel levers (5) (primary levers), which each have at their one end a fork for receiving a bearing journal of the drum (2) and which are mounted by the other end in the region of the axis of the carrier roll in such a way that as the spool swings out of a first position above the carrier roll in the running direction of the web and around the carrier roll (1), it approaches said roll and at the same time runs through a primary section until it reaches a second position, in which the spool with the as yet unfinished roll is taken over by a second pair of swivel levers (12) (secondary levers), the winder also comprising an essentially horizontal guide track which extends from the second position over a secondary section to a third position, and a pressing device for pressing the spool (2) together with the roll forming thereon against the carrier roll (1). The invention is characterised by the following features;   (a) a pair of cam discs (10) is provided, each of which is assigned one of the primary levers (5) such that, together with said lever, they at least partially run through the primary section and at the same time release the spool (2) corresponding to their contour and corresponding to the distance covered;   (b) the cam discs (10) are assigned a drive which rotates the two discs about a horizontal axis. <IMAGE>

Description

Die Erfindung betrifft eine Wickelmaschine gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a winding machine according to the preamble of claim 1.

Derartige Wickelmaschinen, auch "Poperoller" genannt, bilden im allgemeinen die Endpartie einer Papiermaschine, um die dort anfallende Papierbahn in Rollenform zu bringen. Sie werden aber auch dazu benutzt, um eine bereits fertige Rolle umzurollen, damit eine neue Rolle entsteht.Winding machines of this type, also called "pop rollers", generally form the end section of a paper machine in order to bring the paper web obtained there into roll form. However, they are also used to rewind an already finished roll so that a new roll is created.

In jedem Falle soll die Rolle ganz bestimmte Eigenschaften aufweisen, insbesondere was die Wickelhärte betrifft. Die Wickelhärte soll von einem gewissen Anfangswert auf einen Endwert abfallen. Der Abfall soll von der ersten bis zur letzten Lage möglichst gleichmäßig sein. Er soll einen bestimmten Gradienten aufweisen, d.h. nicht zu stark und nicht zu schwach sein. Der Verlauf der Wickelhärte soll auf gar keinen Fall Sprungstellen aufweisen, z.B. einen plötzlichen Abfall.In any case, the roll should have very specific properties, especially as far as the winding hardness is concerned. The winding hardness should drop from a certain initial value to an end value. The waste should be as even as possible from the first to the last layer. It should have a certain gradient, i.e. not too strong and not too weak. The course of the winding hardness should under no circumstances have jump points, e.g. a sudden drop.

All dies wurde bisher angestrebt, jedoch nicht erreicht. Wickelmaschinen bekannter Bauart erzeugen statt dessen Rollen, bei denen der Kern extrem hart ist. Dies hat zur Folge, daß dieser Kern unbrauchbar ist, weil nämlich die Bahn in diesem Bereich überdehnt wird und platzt, so daß dieser Teil als Ausschuß weggeworfen werden muß.So far, all of this has been attempted, but has not been achieved. Instead, winding machines of a known type produce rolls in which the core is extremely hard. The result of this is that this core is unusable, because the web in this area is overstretched and bursts, so that this part must be thrown away as a committee.

Bekannte Mittel zum Beeinflussen der Wickelhärte sind zwei Maßnahmen, die man beispielsweise bei Rollenschneidmaschinen anwendet. Die eine besteht darin, die Bahn beim Aufwickeln einer mehr oder minder starken Zugspannung zu unterwerfen. Die andere Maßnahme besteht darin, die Rolle mehr oder minder stark an die Tragwalze anzupressen, beispielsweise durch Aufbringen eines Druckes auf die Achsen des Tambours, oder durch Anpressen einer Reiterwalze, die parallel zur entstehenden Rolle angeordnet ist und gegen diese angedrückt wird, so daß ein Liniendruck zwischen der Rolle und der Tragwalze entsteht.Known means of influencing the winding hardness are two measures that are used, for example, in slitter rewinder. One is to subject the web to a more or less strong tension when winding it up. The other measure is to keep the role more or less strong Pressing the support roller, for example by applying pressure to the axes of the spool, or by pressing a rider roller, which is arranged parallel to the roll being created and pressed against it, so that a line pressure is created between the roll and the support roll.

Häufig wird in der genannten Primärstrecke durch das Gewicht des Tambours ein Liniendruck zwischen der entstehenden Rolle und der Tragwalze erzeugt. Der Tambour ist außerordentlich schwer. Er erreicht ein Eigengewicht von mehreren Tonnen, so daß ein entsprechend hoher Liniendruck entsteht. Dieser ist für die extrem hohe Wickehärte des Kernes der Rolle verantwortlich.In the primary section mentioned, the weight of the spool frequently creates a line pressure between the resulting roll and the support roller. The drum is extremely heavy. It reaches a dead weight of several tons, so that a correspondingly high line pressure is created. This is responsible for the extremely high winding hardness of the core of the roll.

Um den Liniendruck und damit auch die Wickelhärte im Kernbereich etwas zu verringern, hat man schon Tambour-Entlastungsvorrichtungen angewandt, die im Sinne eines Abhebens des Tambours und damit einer Verringerung des Liniendruckes wirken sollen. Theoretisch ist dies auch der Fall. Jedoch kommt es aufgrund der unvermeidbaren Vibrationen der ganzen Maschine während des Betriebes zu einem "Tanzen", so daß die Entlastung nur mit Vorsicht - und damit wenig wirksam - durchgeführt werden kann, um ein Herausspringen des Tambours aus den Gabeln der beiden ersten Schwenkhebel zu vermeiden. Dem Problem des überharten Kernes war somit bisher nicht beizukommen. Das Problem ließ sich auch dadurch nicht lösen, daß man den Tambour vor dem Abwickeln einer neuen Rolle im oberen Scheitelbereich der Tragwalze auf Wickeldrehzahl brachte, bis die Umfangsgeschwindigkeit von Tambour und Tragwalze synchron waren. Auch das andere Problem - nämlich der oben erwähnte steile Abfall der Wickelhärte im Endbereich - ließ sich bisher nicht lösen. Besonders ungünstig ist während des gesamten Wickelverlaufes die Zeitspanne des Übergebens der entstehenden Rolle von der Primärstrecke an die Sekundärstrecke. Während dieser Zeitspanne ist die Wickelhärte praktisch außer Kontrolle.In order to somewhat reduce the line pressure and thus also the winding hardness in the core area, spool relief devices have already been used, which should act in the sense of lifting the spool and thus reducing the line pressure. In theory, this is also the case. However, due to the unavoidable vibrations of the entire machine during operation, there is a "dancing", so that the relief can only be carried out with caution - and therefore not very effectively - in order to prevent the drum from jumping out of the forks of the first two pivot levers . So far, the problem of the over-hard core could not be solved. The problem could not be solved by bringing the reel to winding speed in the upper apex area of the support roller before unwinding a new reel, until the peripheral speed of the reel and support roller were synchronized. The other problem - namely the steep drop in winding hardness in the end area mentioned above - has not yet been solved. The period of time in which the resulting roll is transferred from the primary section to the secondary section is particularly unfavorable during the entire winding process. During this period, the winding hardness is practically out of control.

Der Erfindung liegt die Aufgabe zugrunde, eine Wickelmaschine gemäß dem Oberbegriff von Patentanspruch 1 derart zu gestalten, daß die Wickelhärte vom Anfang bis zum Ende der Rolle den gewünschten Verlauf hat, d.h. daß die extreme Härte im Kernbereich vermieden wird, und daß sich die Wickelhärte in jedem Augenblick des Wickelvorganges unter Kontrolle befindet. Außerdem soll natürlich der maschinelle Aufwand möglichst gering gehalten werden.The invention has for its object to design a winding machine according to the preamble of claim 1 such that the winding hardness has the desired course from the beginning to the end of the roll, i.e. that the extreme hardness in the core area is avoided and that the winding hardness is under control at every moment of the winding process. In addition, the mechanical effort should of course be kept as low as possible.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Hauptanspruches gelöst.This object is achieved by the characterizing features of the main claim.

Im einzelnen wird durch die Erfindung folgendes erreicht:In particular, the following is achieved by the invention:

Durch die Kurvenscheiben wird eine genau dosierbare Entlastung des großen Tambourgewichtes erreicht. Die beiden Kurvenscheiben können beispielsweise jeweils an einer Achse des Tambours angreifen. Dadurch, daß sie mit den Primärhebeln verbunden sind, durchlaufen sie die Primärstrecke. Durch ihre Verdrehung um ihre eigene, horizontale Achse läßt sich das Maß genau bestimmen, mit welchem die Wirkung des Eigengewichtes des Tambours verringert wird. Dabei kann die Verdrehung der beiden Kurvenscheiben um die eigene Achse beispielsweise derart gestaltet werden, daß zunächst - im oberen Scheitelbereich und damit in der ersten Position - noch keine Berührung zwischen der Mantelfläche der Tragwalze und der Mantelfläche des Tambours stattfindet, daß dies jedoch nach Durchlaufen einiger Winkelgrade der Primärhebel eintritt. Sodann läßt sich durch entsprechendes weiteres Verdrehen der Kurvenscheibe zu jedem Zeitpunkt, d.h. an jedem Punkt der zurückgelegten Strecke, die Linienkraft zwischen Tambour und Tragwalze genau dosieren.The cam disks achieve a precisely metered relief of the large reel weight. The two cams can each engage one axis of the reel, for example. Because they are connected to the primary levers, they pass through the primary path. By twisting it around its own horizontal axis, it is possible to precisely determine the extent to which the effect of the weight of the drum is reduced. The rotation of the two cams around its own axis can be designed, for example, so that initially - in the upper vertex area and thus in the first position - there is still no contact between the outer surface of the support roller and the outer surface of the reel, but this happens after some Angular degrees of the primary lever occurs. Then by further turning the cam accordingly at any time, i.e. precisely meter the line force between the reel and the idler roller at every point along the route.

Es ist ganz wichtig, daß die erfindungsgemäße Einrichtung in der Lage ist, den Tambour derart zu positionieren, daß seine Mantelfläche (bzw. die Mantelfläche des angewickelten Papieres) einen endlichen Abstand zur Mantelfläche der Tragwalze einnimmt, und daß auch dieser Abstand in beliebiger Weise kontinuierlich verändert werden kann, bis schließlich zur Berührung zwischen den beiden genannten Mantelflächen. Diese erfindungsgemäße Eigenschaft ist entscheidend beim Aufwickeln von druckempfindlichen Papieren, beispielsweise sogenannten NC-Papieren (= Ohne-Kohle-Papiere), oder bei hochwertigen gestrichenen Papieren.It is very important that the device according to the invention is able to position the drum in such a way that its outer surface (or the outer surface of the wound paper) is one takes up a finite distance from the lateral surface of the support roller, and that this distance can also be continuously changed in any way, until finally contact between the two named lateral surfaces. This property according to the invention is decisive in the winding of pressure-sensitive papers, for example so-called NC papers (= without carbon papers), or in the case of high-quality coated papers.

Die Erfindung ist anhand der Zeichnung näher erläutert. Die Zeichnung zeigt einen sogenannten Poperoller.The invention is explained in more detail with reference to the drawing. The drawing shows a so-called pop roller.

Ein solcher Poperoller dient zum Aufwickeln einer laufenden Papierbahn. Die Papierbahn ist hier nicht dargestellt, sondern lediglich die aus ihr gebildete Rolle. Die Papierbahn wird in der Zeichnung von der linken Seite her dem Poperoller zugeführt.Such a pop roller is used to wind up a running paper web. The paper web is not shown here, but only the role formed from it. The paper web is fed from the left side of the pop roller in the drawing.

Der Poperoller weist eine bahnbreite Tragwalze 1 auf. Ein Tambour 2 hat an seinen beiden Enden Lagerzapfen 3. Jeder Lagerzapfen ist in der Gabel 4 eines Primärhebels 5 gelagert. Die beiden Primärhebel, die sich demgemäß ebenfalls im Bereich der Stirnseiten der Tragtrommel 1 und damit auch des Tambours 2 befinden, sind mittels eines pneumatischen Antriebes 6a um einen Schwenkpunkt 6b entsprechend dem Pfeil 7 auf einer Kreisbahn verschwenkbar. Dabei kann der Schwenk-Mittelpunkt der Primärhebel 5 gegenüber der Drehachse der Tragwalze 1 etwas versetzt sein. Es ist jedoch ein Vorteil der Erfindung, daß die beiden konzentrisch zueinander sein können.The pop roller has a web-wide support roller 1. A drum 2 has bearing pins 3 at both ends. Each bearing pin is mounted in the fork 4 of a primary lever 5. The two primary levers, which are accordingly also located in the area of the end faces of the carrying drum 1 and thus also the drum 2, can be pivoted about a pivot point 6b according to the arrow 7 on a circular path by means of a pneumatic drive 6a. The pivot center of the primary lever 5 can be offset somewhat from the axis of rotation of the support roller 1. However, it is an advantage of the invention that the two can be concentric with each other.

Der Tambour 2 befindet sich zunächst in seiner Position I, entweder genau oder fast genau senkrecht über der Tragtrommel 1. In dieser Position ist er noch leer, d.h. noch nicht von Papier umwickelt.The drum 2 is initially in its position I, either exactly or almost exactly vertically above the carrying drum 1. In this position, it is still empty, that is, it has not yet been wrapped in paper.

Die Tragtrommel 1 wird sodann im Sinne des Pfeiles 8 angetrieben, und mit ihr der Tambour 2 im Sinne des Pfeiles 9. Damit wird die Papierbahn mehr und mehr auf dem Tambour 2 aufgewickelt. Unter dem Gewicht des Tambours 2 wirken hierbei ganz erhebliche Kräfte auf die Papierbahn ein. Diese Kräfte beeinflussen die Wickelhärte der entstehenden Rolle ganz entscheidend. Da die Rolle auf ihrem Wege entsprechend dem Pfeil 7 an Gewicht gewinnt, wirkt dieses ebenfalls, und beeinflußt damit die Wickelhärte.The carrying drum 1 is then driven in the direction of arrow 8, and with it the drum 2 in the direction of arrow 9. The paper web is thus wound more and more onto the drum 2. Under the weight of the reel 2, very considerable forces act on the paper web. These forces have a decisive influence on the winding hardness of the resulting roll. Since the roll gains weight on its way according to the arrow 7, this also acts and thus influences the winding hardness.

Gemäß der Erfindung ist im Bereich der Enden des Tambours 2 jeweils eine Kurvenscheibe 10 vorgesehen. Die beiden Kurvenscheiben 10 sind jeweils an einem der beiden Primärhebel 5 gelagert. Sie machen somit die Verschwenkbewegung der Primärhebel 5 mit. Die Kurvenscheiben 10 wirken - mittelbar oder unmittelbar - auf den Tambour 2. Sie stützen sich entweder gegen dessen Mantelfläche ab, wohlgemerkt im Randbereich, oder gegen dessen Lagerzapfen 3.According to the invention, a cam 10 is provided in the region of the ends of the drum 2. The two cams 10 are each mounted on one of the two primary levers 5. They thus take part in the pivoting movement of the primary lever 5. The cam disks 10 act - indirectly or directly - on the drum 2. They are supported either against the lateral surface thereof, mind the edge area, or against the bearing journal 3.

Zwischen einer jeden Kurvenscheibe 10 und dem zugehörenden Primärhebel 5 ist eine Meßdose 11 vorgesehen. Diese mißt die Kraft, die zwischen Tambour 2 und Kurvenscheibe 10 herrscht. Auf die Wirkungsweise der Kurvenscheibe 10 und der Meßdose 11 wird weiter unten noch eingegangen werden.A load cell 11 is provided between each cam plate 10 and the associated primary lever 5. This measures the force that prevails between drum 2 and cam 10. The mode of operation of the cam plate 10 and the load cell 11 will be discussed further below.

Die beiden Primärhebel 5 wandern im Laufe des Betriebes des Poperollers zusammen mit dem Tambour 2 und der hierauf befindlichen Teil-Rolle der Papierbahn, wie oben erwähnt - in Richtung des Pfeiles 7 - und gelangen somit von der Position I des Tambours in dessen Position II. In der Position 11 ist die Kurvenbewegung des Tambours mit Teil-Rolle zu Ende. Hier werden Tambour 2 mit Teil-Rolle vom Primärhebelpaar 5 an ein Sekundärhebelpaar 12 abgegeben. Jeder Sekundärhebel hat ebenfalls eine Gabel 13 zur Aufnahme des betreffenden Lagerzapfens 3 des Tambours 2. Ein pneumatischer oder hydraulischer Antrieb 14 greift an den beiden Sekundärhebeln 12 an und verschwenkt die Sekundärhebel nach rechts, so daß der Tambour 2 mit der nunmehr immer weiter wachsenden Papierrolle eine horizontale Sekundärstrecke durchläuft, bis er schließlich die Position III erreicht, wo die Rolle fertig ist.The two primary levers 5 migrate during the operation of the pop roller together with the drum 2 and the partial roll of the paper web located thereon, as mentioned above - in the direction of arrow 7 - and thus move from position I of the drum to its position II. In position 11, the curve movement of the drum with partial roller has ended. Here drum 2 with partial roll are delivered from the primary lever pair 5 to a secondary lever pair 12. Each secondary lever also has a fork 13 for receiving the relevant journal 3 of the reel 2. A pneumatic or hydraulic drive 14 engages the two secondary levers 12 and pivots the secondary levers to the right, so that the reel 2 with the paper roll, which continues to grow, runs through a horizontal secondary section until it finally reaches position III, where the roll is finished.

Bei der ganzen Operation ist vor allem die Primärstrecke im Hinblick auf das Wickelergebnis kritisch, also die Strecke zwischen der Position I und II. Ganz besonders kritisch ist die Übergabephase von der Primärstrecke auf die Sekundärstrecke.In the entire operation, the primary route is particularly critical with regard to the winding result, that is the route between positions I and II. The transfer phase from the primary route to the secondary route is particularly critical.

Die bisher aufgetretenen Probleme werden nunmehr mit den erfindungsgemäßen Kurvenscheiben 10 gelöst. Die Kurvenscheiben 10 und - gegebenenfalls - die Meßdosen 11 arbeiten wie folgt: Sie sind beide angetrieben, und zwar auf der Führerseite und auf der Triebseite des Poperollers in synchronisierter Weise. Dabei ist der Antrieb über Winkelkodierer geregelt. Die beiden Kurvenscheiben bewirken eine Entlastung des Tambour-Gewichtes sowie des Gewichtes der entstehenden Rolle. Es gelingt damit, die Linienkraft zwischen Tragtrommel 1 und Tambour 2 gezielt zu steuern. Dabei werden als Stellgrößen die Winkelposition der Primärhebel 5 sowie die an der Meßdose 11 gemessenen Kräfte herangezogen.The problems previously encountered are now solved with the cam disks 10 according to the invention. The cams 10 and - if necessary - the load cells 11 work as follows: They are both driven, on the driver side and on the drive side of the pop roller in a synchronized manner. The drive is controlled via an angle encoder. The two cams relieve the weight of the reel and the weight of the resulting roll. It is possible to control the line force between the drum 1 and drum 2 in a targeted manner. The angular position of the primary lever 5 and the forces measured on the load cell 11 are used as the manipulated variables.

Die erfindungsgemäße Einrichtung ist in der Lage, den Tambour 2 kontinuierlich derart abzuheben, daß gar keine Berührung mit der Tragtrommel 1 stattfindet. Diese Betriebsweise ist besonders geeignet bei Papieren, die gegen Oberflächendruck empfindlich sind, wie beispielsweise NC-Papiere oder hochwertige gestrichene Papiere.The device according to the invention is able to continuously lift the drum 2 in such a way that there is no contact with the carrying drum 1 at all.
