Definitions

  • the layers move laterally relative to one another, so that the end faces of the finished roll appear frayed and the web edges can be easily damaged.
  • a badly built core does not allow the rest of the roll to be built properly.
  • the problem is particularly serious with pressure sensitive papers, e.g. self-copying (SD) papers, whereby the pressing of the reel with the resulting roll on it is limited against the outer surface of the drum.
  • SD self-copying
  • the resulting paper roll is, as mentioned, shifted in the horizontal direction in accordance with the roll growth.
  • the paper roll has an enormous weight that can exceed 100 tons. For this reason, the paper roll cannot be pressed so sensitively against the pressure drum as it grows that fluctuations in the line force are avoided.
  • Document (8) shows and describes a winding machine for winding a paper web onto a spool with a central drive.
  • This machine includes a winding station, a take-up station and a drive-less pressure roller.
  • the pressure roller lies continuously on the circumference of the secondary winding up to the winding station.
  • the web is guided in such a way that it continuously enters the inlet gap without being looped.
  • the diameter of the pressure roller is as small as that of a normal web guide roller. Due to the lack of sufficient bending stiffness, it is therefore not suitable for the application of line forces of any desired size, especially not for extremely large web widths (up to approx. 10 m).

The winding takes place exclusively by applying the force acting on the circumference.
  • EP 0 483 092 A1 relates to the following method: an empty spool is accelerated to the web speed, then placed on horizontal rails, pressed onto a "winding cylinder", and the start of the web is shown on the empty spool.

  • the invention is based on EP 0 483 092 A1. There is shown a winding machine in which the winding takes place primarily by means of a center drive.
  • the invention has for its object to design a method and an apparatus for winding a running paper web in such a way that the winding hardness of the roll has the desired course from the beginning to the end of the winding process, that is to say that the winding hardness is under control at every moment of the winding process located.
  • the course of the winding hardness should be adjustable as the roll diameter increases; for example, it should be constant or slightly increasing or (preferably) slightly decreasing, but always constant.
  • a particularly high, but sometimes a relatively low winding hardness is usually required (see patent application 195 22 975.4 - PA 10176).
  • the winding hardness should be able to be influenced without the application of a line force between the resulting winding and the outer surface of the pressure roller.
  • the torque for the central reel drive and the line force mentioned must be independently adjustable within wide limits.
  • An additional requirement can be that the longitudinal tension of the incoming web - again independent of the other sizes - is adjustable. Nevertheless, the mechanical effort should of course be kept as low as possible.
  • the inventors first recognized that the poor quality of the windings produced on known winding machines is due to a number of interfering influences. These are in detail: Swiveling the reel along the circumference of the drum during the winding process, abrupt placement of the wound drum on the guideway, impacts and thus irregularities caused by the transfer of the drum from the primary lever pair to the secondary lever pair, irregularities when changing the drives. An important finding is that the properties of the finished paper roll are created to a decisive degree in the first phase of the winding. The inventors have further recognized that even the slightest irregularities during winding can be extremely harmful if these irregularities occur in the first phase mentioned. Such irregularities can consist, for example, in that the paper roll is wound up in a first station, moved to a second station and finished winding in this second station if vibrations occur.
  • the resulting paper roll is kept absolutely still, free of any bumps. If the paper layer wound on the spool has reached a certain thickness, for example 0.2 times the target layer thickness, the spool can be transferred to a finished winding position without this affecting the winding quality. There is also no up and down movement - contrary to the procedure according to document (8). In a variant (claim 8), the reel with the resulting paper roll remains in one and the same "winding position". In all variants, the machine is extremely simple Construction. In addition, the inventors have consistently focused on the central drive, which is the most important means of controlling the course of the winding hardness during the winding process.
  • the pressure roller is designed as a rigid and press-fitted "pressure drum”. This achieves two things:
  • the "wrapped" web tension can be regulated very sensitively by controlling the two drives. Irrespective of this, the line force between the pressure drum and the winding roll can be set as desired within wide limits, for example between 0.2 and 3.0 kN / m, that is, if desired, to very low values.
  • the tried-and-tested center drive is used with simultaneous application of a line force which acts on the jacket of the paper roll being produced, by means of the pressure drum.
  • the line force to be applied to the jacket of the paper roll has an outstanding influence on the winding result.
  • the smallest changes in this line force lead to a disproportionate influence on the winding hardness.
  • Sharp deflections of the roll during winding, especially during winding, are harmful. Such diversions are avoided according to the invention.
  • the paper roll remains essentially in one and the same place during the winding process - either in the winding position, or in the finished winding position. Only the pressure drum is moved in accordance with the roll growth, not the heavy roll itself. The pressure is therefore sensitive.

Abstract

The system is for winding up a strip of paper on a roll (9). When a roll is full, another roll spindle is spun up to speed on an arrangement (7) with a belt (7.3) stretched over two rollers (7.1,7.2). The roll core is then dropped or positively moved down onto the paper web just before it joins the nearly full roll. The paper web is then cut before it joins the full roll, but after the empty roll core. An air blast nozzle blows the paper strip towards the empty roll core, which then catches the loose end of the paper strip and proceeds to roll it up. The support for the full roll is then dropped away and the roll is then removed and the new roll then moves onto the support.

Wickelmaschinen zum Aufwickeln von Papierbahnen können am Ende einer Papiermaschine angeordnet, um die dort anfallende Papierbahn in Rollenform zu bringen (sogenannter Pope-Roller). Sie werden aber auch dazu benutzt, um eine fertige Rolle umzurollen, um Rollen einer ganz bestimmten Wickelqualität herzustellen.Winding machines for winding paper webs can be arranged at the end of a paper machine in order to bring the resulting paper web into roll form (so-called Pope-Roller). However, they are also used to roll over a finished roll in order to produce rolls of a specific winding quality.

In jedem Falle soll der Wickel ganz bestimmte Eigenschaften aufweisen, insbesondere was die Wickelhärte betrifft. Die Wickelhärte soll meistens von einem gewissen Anfangswert auf einen Endwert abfallen, wobei ganz am Anfang eine harte Kernwicklung besonders wichtig ist. 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. Im Wickel dürfen keine die Papierbahn beeinträchtigenden oder zerstörenden Radial- oder Tangentialspannungen auftreten.In any case, the winding should have very specific properties, particularly as far as the winding hardness is concerned. The winding hardness should mostly drop from a certain initial value to a final value, with a hard core winding being particularly important at the very beginning. The waste should be as even as possible from the first to the last layer. It should have a certain gradient, ie not too strong and not too weak. The course of the winding hardness should under no circumstances show jump points, for example a sudden drop. No in the wrap Radial or tangential tensions that impair or destroy the paper web.

All dies wurde bisher angestrebt, jedoch nicht erreicht. Wickelmaschinen bekannter Bauart erzeugen statt dessen z.B. Wickel, bei denen der Kern entweder extrem weich oder extrem hart ist, und bei denen gegen Ende - etwa bei vier Fünftel des Wickeldurchmessers - ein starker Abfall der Wickelhärte eintritt. Dies hat zur Folge, daß der erste Teil, also der extrem weiche oder harte Kern, unbrauchbar ist, weil nämlich die Bahn in diesem Bereich gestaucht wird und platzt, so daß dieser Teil als Ausschuß weggeworfen werden muß; im Endbereich, in dem der Wickel nicht genügend hart gewickelt ist, kommt es zu einem seitlichen Verschieben der Lagen relativ zueinander, so daß die Stirnseiten der fertigen Rolle ausgefranst erscheinen und die Bahnränder leicht beschädigt werden können.So far, all of this has been attempted, but has not been achieved. Instead, winding machines of known design produce e.g. Windings in which the core is either extremely soft or extremely hard, and in which towards the end - around four fifths of the winding diameter - there is a sharp drop in winding hardness. This has the consequence that the first part, ie the extremely soft or hard core, is unusable, because the web is compressed and bursts in this area, so that this part must be thrown away as a committee; in the end region, in which the winding is not wound hard enough, the layers move laterally relative to one another, so that the end faces of the finished roll appear frayed and the web edges can be easily damaged.

Ein schlecht aufgebauter Kern (zu geringe oder zu große Härte) erlaubt nämlich keinen einwandfreien Aufbau des übrigen Wickels. Das Problem ist besonders gravierend bei druckempfindlichen Papieren, z.B. selbstdurchschreibenden (SD-)Papieren, wobei dem Anpressen des Tambours mit dem hierauf befindlichen, entstehenden Wickel gegen die Mantelfläche der Tragtrommel enge Grenzen gesetzt sind.A badly built core (too little or too hard) does not allow the rest of the roll to be built properly. The problem is particularly serious with pressure sensitive papers, e.g. self-copying (SD) papers, whereby the pressing of the reel with the resulting roll on it is limited against the outer surface of the drum.

Bei dem Verfahren gemäß Dokument (1) wird die entstehende Papierrolle, wie erwähnt, in horizontaler Richtung entsprechend dem Rollenwachstum verschoben. Die Papierrolle erreicht ein gewaltiges Gewicht, das hundert Tonnen übersteigen kann. Deswegen kann die Papierrolle bei ihrem Anwachsen gar nicht so feinfühlig gegen die Anpreßtrommel angedrückt werden, daß Schwankungen der Linienkraft vermieden werden.In the method according to document (1), the resulting paper roll is, as mentioned, shifted in the horizontal direction in accordance with the roll growth. The paper roll has an enormous weight that can exceed 100 tons. For this reason, the paper roll cannot be pressed so sensitively against the pressure drum as it grows that fluctuations in the line force are avoided.

Dokument (8) zeigt und beschreibt eine Wickelmaschine zum Aufwickeln einer Papierbahn auf einen Tambour mit Zentralantrieb. Diese Maschine umfaßt eine Wickelstation, eine Aufnahmestation und eine antriebslose Andrückwalze. Die Andrückwalze liegt am Umfang des Sekundärwickels kontinuierlich bis in die Wickelstation an. Die Bahn ist derart geführt, daß sie ständig umschlingungsfrei in den Einlaufspalt eintritt. Der Durchmesser der Andrückwalze ist so klein wie derjenige einer normalen Bahnleitwalze. Sie ist deshalb mangels ausreichender Biegesteifigkeit nicht zum Aufbringen beliebig hoher Linienkräfte geeignet, insbesondere nicht für extrem große Bahnbreiten (bis ca. 10 m).Document (8) shows and describes a winding machine for winding a paper web onto a spool with a central drive. This machine includes a winding station, a take-up station and a drive-less pressure roller. The pressure roller lies continuously on the circumference of the secondary winding up to the winding station. The web is guided in such a way that it continuously enters the inlet gap without being looped. The diameter of the pressure roller is as small as that of a normal web guide roller. Due to the lack of sufficient bending stiffness, it is therefore not suitable for the application of line forces of any desired size, especially not for extremely large web widths (up to approx. 10 m).

Eine besondere Einrichtung fördert dabei einen Sekundärtambour und die mit ihm gekoppelte Andrückwalze bis zum Niveau der Wickelstation, aus welcher eine zuvor aufgewickelte Papierrolle entfernt wurde. Der hierzu notwendige Hubantrieb bedingt eine aufwendige Konstruktion.A special device supports a secondary drum and the pressure roller coupled to it up to the level of the winding station, from which a previously wound paper roll was removed. The lifting drive required for this requires a complex construction.

Dieses Dokument beschreibt das folgende Verfahren:
Ein Leertambour ist zusammen mit der genannten antriebslosen Andrückwalze an einem Vertikalschlitten gelagert. Tambour und Andrückwalze sind an dem genannten Schlitten auf- und abfahrbar. Zunächst wird der Tambour in einer ersten oberen Position angewickelt. Sodann wird er auf horizontale Schienen abgesenkt, zusammen mit der Andrückwalze, und in eine feste erste Position auf den Schienen verbracht. Während dieser Vorgänge läuft der Wickelprozeß weiter. In dieser ersten Position wird die Papierbahn bis zur vollen Rolle aufgewickelt, sodann in eine Abgabeposition verbracht und aus der Maschine entfernt.This document describes the following procedure:
An empty reel is mounted on a vertical slide together with the drive-less pressure roller mentioned. Drum and pressure roller can be moved up and down on the slide mentioned. First the reel is wound in a first upper position. It is then lowered onto horizontal rails, together with the pressure roller, and brought into a fixed first position on the rails. The winding process continues during these processes. In this first position, the paper web is wound up to the full roll, then brought into a delivery position and removed from the machine.

Bei dem Verfahren gemäß Dokument (8) wird der Tambour zwar auch in einer ersten Position nur angewickelt, sodann auf die Schienen abgesenkt und dann in einer zweiten Position fertiggewickelt. Beim Aufsetzen auf die Schienen kann es zu einem Stoß kommen, der die Umfangskraft beeinflußt, so daß es wiederum zu einer unstetigen Wickelhärte kommt.In the method according to document (8), the reel is only wound up in a first position, then lowered onto the rails and then finished in a second position. When placed on the rails, there may be an impact that affects the circumferential force, so that there is again an unsteady winding hardness.

Ein weiterer wichtiger Nachteil dieses Verfahrens besteht darin, daß die Papierbahn direkt in den Preßspalt zwischen Andrückwalze und Tambour eingeführt wird, d.h. ohne daß sie hierbei die Andrückwalze umschlingt. Die Erfinder haben erkannt, daß dies zu Lufteinschlüssen zwischen den einzelnen Lagen der entstehenden Papierrolle führt.Another important disadvantage of this method is that the paper web is introduced directly into the press nip between the pressure roller and the reel, i.e. without it wrapping around the pressure roller. The inventors have recognized that this leads to air pockets between the individual layers of the resulting paper roll.

US 3 857 524 zeigt und beschreibt eine Wickelmaschine, die nach dem Poperoller-Prinzip arbeitet. Eine Tragtrommel dient hierbei u.a. zum Anwerfen eines ersten Tambours. Alternativ hierzu ist eine Tambour-Anwurf-Vorrichtung oder "Beschleunigungseinrichtung" vorgesehen (Sp. 5, Z. 61-67). Der Tambour wird um den Umfang der Tragtrommel herumgeschwenkt und gelangt auf horizontale Schienen, wobei er an die Tragtrommel angedrückt wird. Nach dem Durchtrennen der laufenden Bahn beginnt der Wickelvorgang auf dem Tambour. Mittels der Tragtrommel wird auf den Umfang des Tambours und der entstehenden Papierrolle ein Drehmoment übertragen. Das Aufwickeln erfolgt hierbei ausschließlich durch Aufbringen der am Umfang angreifenden Kraft. Sobald die Papierrolle voll ist, wird sie, angetrieben mittels einer "enveloper roll 31", von der Tragtrommel entfernt, um Raum für einen nachfolgenden Leertambour zu schaffen. Der Nachteil dieser Maschine ist ähnlich wie bei der Maschine gemäß Dokument (1). Hinzu kommt, daß für den Tambour kein Zentralantrieb vorhanden ist. Dadurch ist der Aufbau der Wickelhärte nicht beliebig steuerbar; außerdem kann die Bahnspannung zwischen Tragtrommel und der von dieser entfernten Wickelrolle - für das Durchtrennen der Bahn - nicht beliebig gesteuert werden.US 3 857 524 shows and describes a winding machine that works according to the pop-roller principle. A carrying drum serves among other things. for starting a first drum. Alternatively, a reel spooling device or "acceleration device" is provided (column 5, lines 61-67). The drum is swung around the circumference of the carrier drum and reaches horizontal rails, where it is pressed against the carrier drum. After cutting the running web, the winding process on the reel begins. Torque is transferred to the circumference of the reel and the paper roll that is created by means of the carrying drum. The winding takes place exclusively by applying the force acting on the circumference. As soon as the paper roll is full, driven by an "enveloper roll 31", it is removed from the carrying drum in order to make room for a subsequent empty reel. The disadvantage of this machine is similar to the machine according to document (1). In addition, there is no central drive for the drum. As a result, the build-up of the winding hardness cannot be controlled at will; moreover, the web tension between the carrying drum and the winding roll removed from it - for severing the web - cannot be controlled arbitrarily.

EP 0 483 092 A1 betrifft das folgende Verfahren: Ein Leertambour wird auf Bahngeschwindigkeit beschleunigt, sodann auf horizontale Schienen aufgelegt, an einen "Wickelzylinder" angedrückt, und der Bahnanfang wird auf den Leertambour aufgeführt. Die Papierbahn wird sodann bis zur vollen Rolle aufgewickelt. Dabei ist der Wickelzylinder ortsfest, während der Tambour mit der entstehenden Rolle entsprechend deren Wachstum auf den Schienen verschoben wird. Dabei wirken ein Zentrumsantrieb sowie ein Umfangsantrieb auf die Rolle ein. Ist die Rolle voll, so wird sie in eine Abgabeposition verbracht und aus der Maschine entfernt, während ein neuer Leertambour beschleunigt und auf die Schienen abgesenkt wird. Auch hier ist es (wie bei Dokument 1 und 7) nicht möglich, die Linienkraft zwischen dem Wickelzylinder und der entstehenden Rolle genügend feinfühlig auf beliebige Werte einzustellen.EP 0 483 092 A1 relates to the following method: an empty spool is accelerated to the web speed, then placed on horizontal rails, pressed onto a "winding cylinder", and the start of the web is shown on the empty spool. The paper web is then wound up to the full roll. The winding cylinder is stationary, while the reel with the resulting roll corresponding to its growth on the rails is moved. A center drive and a peripheral drive act on the roller. When the roll is full, it is brought into a delivery position and removed from the machine, while a new empty reel is accelerated and lowered onto the rails. Here too (as with documents 1 and 7) it is not possible to set the line force between the winding cylinder and the resulting roll with sufficient sensitivity to any values.

Die Erfindung geht aus von EP 0 483 092 A1. Dort ist eine Wickelmaschine dargestellt, bei der das Aufwickeln in erster Linie mittels eines Zentrumsantriebes vonstatten geht.The invention is based on EP 0 483 092 A1. There is shown a winding machine in which the winding takes place primarily by means of a center drive.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie eine Vorrichtung zum Aufwickeln einer laufenden Papierbahn derart zu gestalten, daß die Wickelhärte der Rolle vom Anfang bis zum Ende des Wickelvorganges den gewünschten Verlauf hat, d.h. daß sich die Wickelhärte in jedem Augenblick des Wickelvorganges unter Kontrolle befindet. Mit anderen Worten: Der Verlauf der Wickelhärte soll mit zunehmendem Rollendurchmesser beliebig einstellbar sein; er soll z.B. konstant oder leicht zunehmend oder (bevorzugt) leicht abnehmend, immer jedoch stetig sein. Im Kernbereich wird meistens eine besonders hohe, manchmal aber auch eine relativ geringe Wickelhärte verlangt (s. Patentanmeldung 195 22 975.4 - PA 10176). Dabei soll die Wickelhärte bei Bedarf auch ohne das Aufbringen einer Linienkraft zwischen dem entstehenden Wickel und der Mantelfläche der Anpreßwalze beeinflußt werden können. Anders ausgedrückt: Das Drehmoment für den zentralen Tambourantrieb und die genannte Linienkraft müssen in weiten Grenzen voneinander unabhängig einstellbar sein. Eine zusätzliche Forderung kann darin bestehen, daß die Längsspannung der zulaufenden Bahn - wiederum unabhängig von den anderen Größen - einstellbar ist. Trotzdem soll natürlich der maschinelle Aufwand möglichst gering gehalten werden.The invention has for its object to design a method and an apparatus for winding a running paper web in such a way that the winding hardness of the roll has the desired course from the beginning to the end of the winding process, that is to say that the winding hardness is under control at every moment of the winding process located. In other words: the course of the winding hardness should be adjustable as the roll diameter increases; for example, it should be constant or slightly increasing or (preferably) slightly decreasing, but always constant. In the core area, a particularly high, but sometimes a relatively low winding hardness is usually required (see patent application 195 22 975.4 - PA 10176). If necessary, the winding hardness should be able to be influenced without the application of a line force between the resulting winding and the outer surface of the pressure roller. In other words, the torque for the central reel drive and the line force mentioned must be independently adjustable within wide limits. An additional requirement can be that the longitudinal tension of the incoming web - again independent of the other sizes - is adjustable. Nevertheless, the mechanical effort should of course be kept as low as possible.

Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst.This object is solved by the features of the independent claims.

Die Erfinder haben zunächst erkannt, daß die mangelhafte Qualität der auf bekannten Wickelmaschinen erzeugten Wickel auf eine Reihe von Störeinflüssen zurückgeht. Diese sind im einzelnen:
Schwenken des Tambours während des Wickelvorganges entlang des Umfangs der Trommel,
stoßartiges Aufsetzen des angewickelten Tambours auf die Führungsbahn, Stöße und damit Unregelmäßigkeiten, verursacht durch die Übergabe des Tambours vom Primärhebel-Paar an das Sekundärhebel-Paar, Unregelmäßigkeiten beim Wechsel der Antriebe. Eine wichtige Erkenntnis besteht darin, daß die Eigenschaften der fertigen Papierrolle in entscheidendem Maße in der ersten Phase des Aufwickelns geschaffen werden. Die Erfinder haben weiterhin erkannt, daß selbst geringste Unregelmäßigkeiten beim Aufwickeln äußerst schädlich sein können, sofern sich diese Unregelmäßigkeiten in der genannten ersten Phase ereignen. Derartige Unregelmäßigkeiten können beispielsweise darin bestehen, daß die Papierrolle in einer ersten Station angewickelt, zu einer zweiten Station verbracht und in dieser zweiten Station fertiggewickelt wird, wenn hierbei Erschütterungen auftreten.The inventors first recognized that the poor quality of the windings produced on known winding machines is due to a number of interfering influences. These are in detail:
Swiveling the reel along the circumference of the drum during the winding process,
abrupt placement of the wound drum on the guideway, impacts and thus irregularities caused by the transfer of the drum from the primary lever pair to the secondary lever pair, irregularities when changing the drives. An important finding is that the properties of the finished paper roll are created to a decisive degree in the first phase of the winding. The inventors have further recognized that even the slightest irregularities during winding can be extremely harmful if these irregularities occur in the first phase mentioned. Such irregularities can consist, for example, in that the paper roll is wound up in a first station, moved to a second station and finished winding in this second station if vibrations occur.

All dies wird vermieden durch Anwendung der Erfindung. Während des kritischen Bereiches des Anwickelns wird die entstehende Papierrolle absolut ruhig gehalten, frei von irgendwelchen Stößen. Hat die auf den Tambour aufgewickelte Papierschicht eine bestimmte Dicke erreicht, beispielsweise das 0,2-fache der Soll-Schichtdicke, so kann der Tambour in eine Fertigwickelposition überführt werden, ohne daß dies der Wickelqualität schadet. Auch eine Auf- und Abbewegung unterbleibt - entgegen dem Verfahren gemäß Dokument (8). In einer Variante (Anspruch 8) verbleibt der Tambour mit der entstehenden Papierrolle dauernd in ein und derselben "Wickelposition". In allen Varianten wird die Maschine extrem einfach im Aufbau. Außerdem haben sich die Erfinder konsequent auf den Zentralantrieb konzentriert, der das wichtigste Mittel ist, um den Verlauf der Wickelhärte während des Wickelvorganges zu steuern. Dies hat den Vorteil, daß durch das zentral aufgebrachte Drehmoment eine "eingewickelte" Bahnspannung entsteht, die völlig stetig ist, und die während des gesamten Wickelvorganges hinweg konstant gehalten oder stetig verändert werden kann. Es treten somit keinerlei Sprungstellen der Bahnspannung auf, so daß die Wickelhärte während des gesamten Wickelvorganges unter Kontrolle gehalten wird, indem sie auf jeden beliebigen Wert einstellbar ist. Abweichend von Dokument (8) ist die Andrückwalze als eine biegesteife und mit einem Antrieb versehene "Anpreßtrommel" ausgebildet. Dadurch wird zweierlei erreicht: Die "eingewickelte" Bahnspannung kann durch Steuern der beiden Antriebe besonders feinfühlig geregelt werden. Davon unabhängig ist die Linienkraft zwischen Anpreßtrommel und Wickelrolle in weiten Grenzen beliebig einstellbar, z.B. zwischen 0,2 und 3,0 kN/m, also auch, falls gewünscht, auf sehr niedrige Werte.All of this is avoided by applying the invention. During the critical area of winding, the resulting paper roll is kept absolutely still, free of any bumps. If the paper layer wound on the spool has reached a certain thickness, for example 0.2 times the target layer thickness, the spool can be transferred to a finished winding position without this affecting the winding quality. There is also no up and down movement - contrary to the procedure according to document (8). In a variant (claim 8), the reel with the resulting paper roll remains in one and the same "winding position". In all variants, the machine is extremely simple Construction. In addition, the inventors have consistently focused on the central drive, which is the most important means of controlling the course of the winding hardness during the winding process. This has the advantage that the centrally applied torque creates a "wrapped" web tension that is completely steady and that can be kept constant or changed continuously during the entire winding process. There are therefore no jumps in the web tension, so that the winding hardness is kept under control during the entire winding process by being adjustable to any value. Deviating from document (8), the pressure roller is designed as a rigid and press-fitted "pressure drum". This achieves two things: The "wrapped" web tension can be regulated very sensitively by controlling the two drives. Irrespective of this, the line force between the pressure drum and the winding roll can be set as desired within wide limits, for example between 0.2 and 3.0 kN / m, that is, if desired, to very low values.

Gemäß der Erfindung wird der bewährte Zentrumsantrieb eingesetzt, bei gleichzeitigem Aufbringen einer Linienkraft, die am Mantel der entstehenden Papierrolle angreift, und zwar mittels der Anpreßtrommel.According to the invention, the tried-and-tested center drive is used with simultaneous application of a line force which acts on the jacket of the paper roll being produced, by means of the pressure drum.

Die Erfinder haben im einzelnen folgendes erkannt:
Die auf den Mantel der Papierrolle aufzubringende Linienkraft hat auf das Wickelergebnis einen überragenden Einfluß. Kleinste Veränderungen dieser Linienkraft führen zu einer überproportionalen Beeinflussung der Wickelhärte. Scharfe Umlenkungen der Rolle wärend des Wickelns, besonders während des Anwickelns, sind schädlich. Gemäß der Erfindung werden solche Umlenkungen vermieden.The inventors recognized the following in detail:
The line force to be applied to the jacket of the paper roll has an outstanding influence on the winding result. The smallest changes in this line force lead to a disproportionate influence on the winding hardness. Sharp deflections of the roll during winding, especially during winding, are harmful. Such diversions are avoided according to the invention.

Ferner verbleibt die Papierrolle während des Wickelvorganges im wesentlichen an ein und derselben Stelle - entweder in der Anwickelposition, oder in der Fertigwickelposition. Nur die Anpreßtrommel wird entsprechend dem Rollenwachstum verschoben, nicht die schwere Rolle selbst. Die Anpressung ist daher feinfühlig.Furthermore, the paper roll remains essentially in one and the same place during the winding process - either in the winding position, or in the finished winding position. Only the pressure drum is moved in accordance with the roll growth, not the heavy roll itself. The pressure is therefore sensitive.

Die Erfindung ist anhand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.

Dabei zeigen die Figuren 1 bis 6 sechs verschiedene Arbeitsphasen einer ersten Ausführungsform einer erfindungsgemäßen Wickelmaschine.Figures 1 to 6 show six different working phases of a first embodiment of a winding machine according to the invention.

Die Figuren 7 bis 9 sowie 10 und 11 zeigen weitere Ausführungsbeispiele.FIGS. 7 to 9 and 10 and 11 show further exemplary embodiments.

Die Maschine umfaßt einen Horizontalschlitten 1, der auf einer Führungsbahn 2 in horizontaler Richtung verfahrbar ist. Der Horizontalschlitten 1 trägt eine Anpreßtrommel 3. Diese weist einen Antrieb auf. Die Lager 3a der Anpreßtrommel 3 sind mittels eines Kurzhub-Kraftgebers 3.1 ("Sensomat") auf dem Horizontalschlitten 1 ebenfalls horizontal verfahrbar. Der Horizontalschlitten 1 trägt weiterhin einen Schaber 3.2 zum vorübergehenden Führen der Papierbahn (als Ausschuß) nach unten.The machine comprises a horizontal slide 1 which can be moved in the horizontal direction on a guideway 2. The horizontal slide 1 carries a pressure drum 3. This has a drive. The bearings 3a of the pressure drum 3 can also be moved horizontally on the horizontal slide 1 by means of a short-stroke force sensor 3.1 (“Sensomat”). The horizontal slide 1 also carries a scraper 3.2 for temporarily guiding the paper web (as a committee) downwards.

In einem horizontalen Abstand vom Horizontalschlitten 1 befindet sich eine Vorrichtung 4 zum flächigen Unterstützen der entstehenden Papierrolle 9 (Stützvorrichtung). Die Stützvorrichtung 4 ist hier nur schematisch angedeutet. Sie kann unterschiedliche Ausführungsformen haben. So kann sie beispielsweise zwei zur Papierrolle parallele Walzen umfassen, die von einem Stützband umschlungen sind.At a horizontal distance from the horizontal slide 1 there is a device 4 for supporting the resulting paper roll 9 (support device). The support device 4 is only indicated schematically here. It can have different embodiments. For example, it can comprise two rollers parallel to the paper roll, which are wrapped in a support belt.

Im Bereich der Stützvorrichtung 4 ist eine Andrückrolle 5 vorgesehen. Diese erstreckt sich über die gesamte Breite der Papierrolle 9.A pressure roller 5 is provided in the area of the support device 4. This extends over the entire width of the paper roll 9.

Dem neuen Tambour 8 ist eine Vorrichtung 7 zu dessen Beschleunigen zugeordnet (Beschleunigungsvorrichtung). Im vorliegenden Falle umfaßt die Beschleunigungsvorrichtung Rollen 7.1, 7.2 sowie ein Antriebsband 7.3.The new drum 8 is assigned a device 7 for accelerating it (acceleration device). In the present case, the acceleration device comprises rollers 7.1, 7.2 and a drive belt 7.3.

Bei der in Fig. 1 dargestellten Arbeitsphase ist die Papierrolle 9 nahezu fertiggewickelt. Der Horizontalschlitten 1 befindet sich in [s]einer rechten [Extrem]position. Die Anpreßtrommel 3 liegt noch am Umfang der Papierrolle 9 an. Die Andrückwalze 5 liegt hingegen noch nicht am Umfang der Papierrolle 9 an.In the working phase shown in Fig. 1, the paper roll 9 is almost finished. The horizontal slide 1 is in a right [extreme] position. The pressure drum 3 is still on the circumference of the paper roll 9. The pressure roller 5, however, is not yet on the circumference of the paper roll 9.

Bei der Phase gemäß Fig. 2 ist der Horizontalschlitten 1 in seine linke Extremposition (Ausgangsposition) zurückgefahren. Die Andrückrolle 5 liegt nunmehr am Umfang der Papierrolle 9 an. Sie wurde bereits vor dem Abfahren des Horizontalschlittens 1 angelegt, so daß es keine andruckfreie Zeitspanne gibt. Der neue Leertambour 8 befindet sich in Bereitschaftsposition und wird auf die Geschwindigkeit der Papierbahn 10 beschleunigt.In the phase according to FIG. 2, the horizontal slide 1 has moved back into its left extreme position (starting position). The pressure roller 5 is now on the circumference of the paper roll 9. It was created before the horizontal slide 1 was driven, so that there is no pressure-free period. The new empty reel 8 is in the standby position and is accelerated to the speed of the paper web 10.

Bei der Phase gemäß Fig. 3 ist der neue Leertambour 8 in seine Arbeitsposition abgesenkt. Hierbei liegt er auf einem Schienenpaar, das hier nicht weiter dargestellt ist, das sich aber in horizontaler Richtung erstreckt und unterhalb der Achsen der Anpreßtrommel 3, des Tambours 8 und der Papierrolle 9 verläuft.3, the new empty reel 8 is lowered into its working position. Here it lies on a pair of rails, which is not shown here, but which extends in the horizontal direction and runs below the axes of the pressure drum 3, the spool 8 and the paper roll 9.

Bei der Phase gemäß Fig. 4 wurde die Papierbahn 10 durchtrennt, so daß ein Bahnanfang entsteht. Dieser wird mit Hilfe einer Blasdüse am Schaber 3.2 sowie einer weiteren Blasdüse 3.3 auf dem Tambour 8 angewickelt.In the phase according to FIG. 4, the paper web 10 was cut through, so that a web start is formed. This is wound on the scraper 3.2 with the aid of a blowing nozzle and a further blowing nozzle 3.3 on the reel 8.

Bei der Phase gemäß Fig. 5 hat die neue Papierrolle 9.1 einen gewissen Durchmesser (besser: eine gewisse Schichtdicke) erreicht. Die fertige Papierrolle 9 hingegen wurde bereits aus der Maschine entfernt. Bei der Phase gemäß Fig. 6 befindet sich die neue, entstehende Papierrolle 9.1 in der Fertigwickelposition auf der Stützvorrichtung 4. Sie wurde dorthin auf den genannten Schienen verfahren, wobei ihr der Horizontalschlitten 1 mit der Anpreßtrommel 3 folgte, wobei die Mantelflächen der entstehenden Papierrolle 9.1 und der Anpreßtrommel 3 ständig aneinander anlegen.5, the new paper roll 9.1 has reached a certain diameter (better: a certain layer thickness). The finished paper roll 9, however, has already been removed from the machine. In the 6 is the new, emerging paper roll 9.1 in the finished winding position on the support device 4. It was moved there on the rails mentioned, followed by the horizontal slide 1 with the pressure drum 3, the lateral surfaces of the resulting paper roll 9.1 and Apply pressure drum 3 to each other constantly.

Bei der Ausführungsform gemäß der Figuren 7 bis 9 ist die Wickelmaschine mit einer Niederhaltevorrichtung 12 ausgerüstet. Diese umfaßt einen Schwenkarm 12.1 mit einer Niederhalterolle 12.2. Die Figuren 7 bis 9 veranschaulichen drei verschiedene Phasen. Bei der in Fig. 7 dargestellten Phase ist die Niederhaltevorrichtung in ihre funktionslose Position geschwenkt.In the embodiment according to FIGS. 7 to 9, the winding machine is equipped with a hold-down device 12. This includes a swivel arm 12.1 with a hold-down roller 12.2. Figures 7 to 9 illustrate three different phases. In the phase shown in FIG. 7, the hold-down device is pivoted into its non-functional position.

Bei der Phase gemäß Fig. 8 sind Horizontalschlitten 1 und fertige Papierrolle 9 in horizontaler Richtung voneinander getrennt, so daß ein Zwischenraum für das Herabfahren des neuen Tambours 8 geschaffen wird.In the phase according to FIG. 8, the horizontal slide 1 and the finished paper roll 9 are separated from each other in the horizontal direction, so that a space for the descent of the new reel 8 is created.

Bei der Phase gemäß Fig. 9 ist die Niederhaltevorrichtung 12 in ihre Arbeitsposition eingeschwenkt, in der sie die Papierbahn 10 niederhält. Deshalb konnte der neue Leertambour 8 auf die Schienen abgesenkt werden, ohne vorher angeworfen zu werden.In the phase according to FIG. 9, the hold-down device 12 is pivoted into its working position, in which it holds the paper web 10 down. Therefore, the new empty reel 8 could be lowered onto the rails without being started.

Es besteht somit die Möglichkeit, ihn jetzt an einen Zentralantrieb zu koppeln. Dieser beschleunigt sodann den Leertambour 8 auf die Maschinengeschwindigkeit, wonach die Niederhaltevorrichtung 12 wieder hochgeschwenkt wird. Gleichzeitig bewegt sich der Horizontalschlitten 1, so daß Anpreßtrommel 3 und Tambour 8 in Kontakt kommen und ein neuer Wickelvorgang gemäß den Figuren 4 bis 9 ablaufen kann.It is now possible to couple it to a central drive. This then accelerates the empty drum 8 to the machine speed, after which the hold-down device 12 is pivoted up again. At the same time, the horizontal slide 1 moves, so that the pressure drum 3 and drum 8 come into contact and a new winding process according to FIGS. 4 to 9 can take place.

Figur 10 veranschaulicht den Verfahrensablauf, so wie in Anspruch 8 definiert, und zwar in drei Phasen, A, B und C des Wickelvorganges. Die Positionen der entstehenden bzw. fertigen Papierrolle sind dabei mit I und II gekennzeichnet.Figure 10 illustrates the process flow as defined in claim 8, in three phases, A, B and C of the winding process. The positions the resulting or finished paper roll is marked with I and II.

In der Phase A steht der Wickelvorgang kurz vor seinem Ende; die Wickelrolle 9 befindet sich in Wickelposition.In phase A, the winding process is nearing its end; the winding roller 9 is in the winding position.

In der Position B befindet sich die Wickelrolle 9 in ihrer Endposition; ein neuer Leertambour 8 wird auf Bahngeschwindigkeit beschleunigt.In position B, the winding roll 9 is in its end position; a new empty reel 8 is accelerated to web speed.

In der Position C ist der Leertambour 8 in die Wickelposition eingesetzt.In position C, the empty reel 8 is inserted into the winding position.

Figur 11 zeigt denselben Gegenstand wie Figur 10, jedoch ohne Druckwalze 5. Hierbei geht die Anpreßtrommel 3 kurzzeitig mit der Wickelrolle 9 in die Endposition.FIG. 11 shows the same object as FIG. 10, but without pressure roller 5. Here, the pressure drum 3 briefly goes into the end position with the winding roller 9.
