Abstract

The roller winding machine has a first support element with circumferential supporting surface and a second support element formed by at least one belt (6) guided over at least two guide pulleys (7,8) and made permeable to dust, e.g. perforated, so that the dust can be removed from the space underneath the upper string (10) of the belt through a dust discharge device. A suction device with suction box (12) can be used to remove dust. Several belts can be arranged axially spaced from each other.

Description

Die Erfindung betrifft eine Rollenwickeleinrichtung zum Aufwickeln einer zulaufenden Materialbahn zu einer Wickelrolle mit einem ersten Stützelement, das eine umlaufende Stützfläche aufweist, und einem zweiten Stützelement, das durch mindestens ein Band gebildet ist, das über mindestens zwei Umlenkrollen geführt ist, deren Rotationsachsen parallel zur Achse der Wickelrolle angeordnet sind.The invention relates to a reel winding device for winding a tapered Material web to a winding roll with a first support member having a circumferential Supporting surface, and a second support member by at least one Band is formed, which is guided over at least two pulleys whose axes of rotation are arranged parallel to the axis of the winding roll.

Eine derartige Rollenwickeleinrichtung ist aus DE 36 39 244 C2 bekannt. Das erste Stützelement ist durch eine Tragwaize gebildet. Zwischen der Tragwalze und dem Band ist ein Wickelbett ausgebildet, in dem die Wickelrolle bis zu einem vorbestimmten Durchmesser ruht. Wenn der Durchmesser der Wickelrolle darüber hinaus anwächst, wird das Gewicht der Wickelrolle zunehmend auf das obere Trum des Bandes verlagert. Damit möchte man die Druckspannung vermindem, die sich zwischen der Wickelrolle und den Stützelementen ergibt. Das Band stellt mit seinem oberen Trum eine vergrößerte Auflagefläche zur Verfügung, so daß die Druckspannungen entsprechend abnehmen. Die Druckspannungen in den Auflagenips sind mit ein Kriterium für die Wickelhärte der Wickelrolle. Die Wickelhärte soll dabei von innen nach außen abnehmen oder zumindest konstant bleiben.Such a reel winding device is known from DE 36 39 244 C2. The first Support element is formed by a Tragwaize. Between the carrier roll and the Band is formed a winding bed in which the winding roll to a predetermined Diameter rests. As the diameter of the winding roll increases beyond that, The weight of the winding roll is increasingly on the upper run of the tape relocated. So you want to reduce the compressive stress, which is between the winding roll and the support elements results. The band represents with its upper Trum an enlarged contact surface available, so that the compressive stresses accordingly lose weight. The compressive stresses in the support chips are one of the criteria for the winding hardness of the winding roll. The winding hardness should be from the inside out decrease or at least remain constant.

Allerdings kann man beobachten, daß Papierbahnen, die in einer derartigen Rollenwickeleinrichtung zu Wickelrollen aufgewickelt worden sind, beim Bedrucken gelegentlich Probleme zeigen.However, one can observe that paper webs used in such a reel winding device to winding rolls have been wound up, when printing occasionally Show problems.

Der Erfindung liegt die Aufgabe zugrunde, die Bedruckbarkeit einer in einer derartigen Rollenwickeleinrichtung aufgewickelten Papierbahn zu verbessem.The invention is based on the object, the printability of a in such Roll winding device wound paper web to Improve.

Diese Aufgabe wird bei einer Rollenwickeleinrichtung der eingangs genannten Art dadurch gelöst. daß das Band staubdurchlässig ausgebildet ist und eine Staubabführeinrichtung zur Entfernung von Staub aus einem Raum unterhalb des oberen Trums des Bandes vorgesehen istThis object is achieved in a roll winding device of the type mentioned solved by it. in that the band is permeable to dust and a dust removal device to remove dust from a space below the upper run of the Bandes is provided

Man geht davon aus, daß die Probleme bei der Bedruckbarkeit unter anderem auf Staub zurückzuführen ist, der sich beim Wickeln ergibt. Ursächlich für die Staubentwicklung sind möglicherweise Mikrofriktionen zwischen der Wickelrolle und dem Band. Dieser Staub schlägt sich nicht nur unkontrolliert auf der Rollenwickeleinrichtung nieder, sondern er gerät auch zwischen die einzelnen Lagen der Wickelrolle. Wenn man nun das Band staubdurchlässig macht, dann schafft man einen Pfad, durch den der Staub entfernt werden kann. Die Staubentfernung wird durch die Staubabführeinrichtung noch gefördert. Das Band kann natürlich auch über mehr als zwei Umlenkrollen geführt werden. Auch in derartigen Fällen wird man aber den Staub unterhalb des oberen Trums des Bandes abführen können, d.h. des Teils des Bandes, auf dem die Wickelrolle beim Wickeln aufliegt.It is believed that the printability problems include, among others Dust that results from winding. Cause of the dust development There may be microtractions between the reel and the belt. This dust not only settles uncontrollably on the reel winder, but he also gets between the individual layers of the winding roll. If now the tape makes it permeable to dust, then creates a path through which the Dust can be removed. The dust removal is by the dust removal device still encouraged. Of course, the band can also have more than two pulleys be guided. Even in such cases but you will see the dust below the top Runs of the band can dissipate, i. the part of the tape on which the winding roll during winding rests.

Vorzugsweise weist das Band eine flächige Perforation auf. Eine flächige Perforation besteht aus einer Vielzahl von Löchern oder anderen Durchbrechungen, die zumindest annähernd gleichförmig übedas Band verteilt sind. Der Staub kann durch diese Löcher und damit durch das Band hindurchtreten. Der Abstand der Löcher zueinander und die Größe der Löcher sind dabei so aufeinander abgestimmt, daß das Band die notwendige Festigkeit behält und gleichzeitig keine Markierungen auf der Bahn erzeugt werden.Preferably, the band has a flat perforation. A flat perforation consists of a large number of holes or other openings, at least Almost uniform over the band are distributed. The dust can through this Holes and thus pass through the tape. The distance between the holes and the size of the holes are coordinated so that the tape the necessary Maintains strength and at the same time produces no markings on the web become.

Bevorzugterweise weist zumindest die Umlenkrolle, die dem ersten Stützelement benachbart ist, eine gasundurchlässige Oberfläche auf. Solange also das Band auf dieser Umlenkrolle aufliegt, ist ein Staubdurchtritt nicht möglich. Gleichzeitig ist aber auch ein Gasdurchtritt nicht möglich, so daß man, falls erforderlich, zwischen dem ersten Stützelement und der Umlenkrolle ein Druckluftpolster erzeugen kann, was ebenfalls zur Gewichtsentlastung der Wickelrolle dient Preferably, at least the deflection roller, which is the first support element adjacent to a gas impermeable surface. So long as the tape on this deflection roller rests, a dust passage is not possible. But at the same time Gas passage is not possible, so that, if necessary, between the first Support element and the pulley can produce a compressed air cushion, which also for weight relief of the winding roll is used

Vorzugsweise ist die Staubabführeinrichtung als Saugeinrichtung ausgebildet Mit Hilfe einer Saugeinrichtung kann man den Staub durch das Band hindurch saugen und gleichzeitig aus dem Raum unterhalb des oberen Trums des Bandes entfernen. Der hierfür erforderliche Unterdruck muß nicht sehr groß sein. Er kann sogar geringer sein als ein Unterdruck, den man zum Ansaugen der Bahn an einer Walze oder einem anderen Transportelement benötigt, um die Bahn in ihre Wickelposition zu transportieren.Preferably, the dust removal device is designed as a suction device with Help a suction device can suck the dust through the tape and at the same time remove from the space below the upper run of the tape. The required negative pressure must not be very large. He can even lower be as a negative pressure, which is used to suck the web on a roller or a another transport element needed to transport the web in its winding position.

Hierbei ist bevorzugt, daß die Saugeinrichtung mindestens einen Saugkasten aufweist, der zwischen dem oberen Trum und dem unteren Trum des Bandes angeordnet ist und dessen dem oberen Trum des Bandes zugewandte Oberseite mindestens eine Ansaugöffnung aufweist. Durch den Saugkasten läßt sich das Volumen begrenzen, in dem der Unterdruck erzeugt werden muß. Durch den Saugkasten wird also der Luftverbrauch beim Absaugen des Staubes klein gehalten.It is preferred that the suction device has at least one suction box, which is arranged between the upper run and the lower run of the band is and the upper strand of the band facing top at least having a suction opening. Through the suction box, the volume can be limited, in which the negative pressure must be generated. By the suction box so is the Air consumption while sucking the dust kept small.

Hierbei ist von Vorteil, wenn der Saugkasten den Umlenkrollen benachbarte Seitenwände aufweist, die der Form der Umlenkrollen angepaßt sind. In diesem Fall läßsich die Größeder Ansaugöffnung oder der Ansaugöffnungen maximieren.It is advantageous if the suction box the pulleys adjacent side walls has, which are adapted to the shape of the pulleys. In this case, you can maximize the size of the suction port or ports.

Bevorzugterweise weist Saugeinrichtung einen seitlichen Anschlußstutzen zum Anschließen einer Saugleitung auf. Der Staub wird also seitlich aus der Rollenwickeleinrichtung herausgeführt. Dies hat den Vorteil, daß in der axialen Länge der Rollenwickeleinrichtung keine Unterbrechungen vorgesehen sein müssen.Preferably, suction means comprises a lateral connecting piece for connection a suction line. The dust is thus from the side of the reel winding device led out. This has the advantage that in the axial length of the reel winder no interruptions must be provided.

Vorzugsweise sind mehrere Bänder mit axialem Abstand zueinander angeordnet, und die Saugeinnchtung ist auch im Bereich der Abstände wirksam. Das zweite Stützelement kann also nicht nur ein Band aufweisen, das über die gesamte axiale Erstreckung der Rollenwickeleinrichtung durchgeht, sondern es kann aus einer Vielzahl von schmaleren Bändem gebildet sein, deren Breite beispielsweise 200 mm beträgt. Diese Bänder sollen im Betrieb nicht aneinander anstoßen, um eine zusätzliche Staubentwicklung zu vermeiden. Dementsprechend sind Kleiner Abstände zwischen den Bändern vorgesehen, deren Größern Bereich von 5 mm bis etwa 20 mm liegt. Wenn man auch durch diese Abstände zwischen den Bändern hindurch saugen kann, dann wird auch dort Staub entfernt. Der Staub wird hier sogar ohne Behinderung abgesaugt, so daß die Saugwirkung verbessert werden kann.Preferably, a plurality of bands are arranged at an axial distance from each other, and The suction is also effective in the range of distances. The second support element Thus, not only can a band have that over the entire axial extent passes through the reel winder, but it can from a variety of be formed narrower bands whose width is for example 200 mm. These Ribbons should not abut against each other during operation, in order to generate additional dust to avoid. Accordingly, smaller distances between the bands whose size ranges from 5 mm to about 20 mm. If you too through these distances between the bands can suck through, then will there dust removed. The dust is sucked out even without hindrance, so that the suction effect can be improved.

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

The invention will be described below with reference to a preferred embodiment in conjunction with the drawings. Herein show:

Fig. 1 zeigt eine Rollenwickeleinrichtung 1 zum Aufwickeln einer Papierbahn 2 zu einer Wickelrolle 3. Die Wickelrolle wird beim Wickeln abgestützt auf einer Walze 4, die ein erstes Stützelement 5 bildet, und auf einem Band 6, das über zwei Umlenkrollen 7, 8 geführt ist, und ein zweites Stützelement 9 bildet Das Band 6 kann natürlich auch noch über mehr als die beiden dargestellten Umlenkrollen 7, 8 geführt werden, wie des beispielsweise aus DE 36 39 244 C2 bekannt ist. Die Wickelrolle 3 liegt mit zunehmendem Durchmesser immer stärker auf dem oberen Trum 10 des Bandes 6 auf. Mit zunehmendem Durchmesser der Wickelrolle 3 steigt ihr Gewicht an. Dies würde ohne zusätzliche Maßnahmen dazu führen, daßlie Druckspannungen in den Auflageflächen der Wickelrolle 3 auf den beiden Stützelementen 5, 9 ansteigt. Die Druckspannungen sind aber mitbestimmend für die Wickelhärte. Dementsprechend würde die Wickelhärte der Wickelrolle 3 ansteigen, was nicht gewünscht ist. Dadurch, daß man die Wickelrolle 3 mit Hilfe des Bandes 6 auf einer größeren Fläche abstützen kann, wird ein unerwünschter Anstieg der Druckspannungen vermieden.Fig. 1 shows a reel winding device 1 for winding a paper web 2 to a winding roll 3. The winding roll is supported during winding on a roll 4, which forms a first support element 5, and on a belt 6, via two pulleys 7, 8 is guided, and a second support member 9 forms the band 6 can of course also be guided over more than the two pulleys 7, 8 shown, as is known for example from DE 36 39 244 C2. The winding roll 3 is with increasing diameter on the upper run 10 of the belt 6 on. As the diameter of the winding roll 3 increases, its weight increases. This would lead without additional measures thatlielie compressive stresses in the bearing surfaces the winding roller 3 on the two support members 5, 9 increases. The compressive stresses but are decisive for the winding hardness. Accordingly, would the winding hardness of the winding roll 3 rise, which is not desirable. As a result of that you can support the winding roll 3 by means of the belt 6 on a larger area, an undesirable increase in compressive stresses is avoided.

In nicht näher dargestellter, aber an sich bekannter Weise kann die Papierbahn 2 vor dem Aufwickeln noch durch Längsschnitte in mehrere Teilbahnen unterteilt werden, die dann jeweils zu Teilbahnrollen aufgewickelt werden. Alle Wickelrollen haben dann im wesentlichen die gleichen Wickelachsen 11.In a manner not shown, but known per se, the paper web 2 before the winding still be divided by longitudinal sections into several partial webs, which are then each wound to partial web roles. All bobbins have then essentially the same winding axes 11.

Zwischen den beiden Umlenkrollen 7, 8 und unterhalb des oberen Trums 10 des Bandes 6 ist ein Saugkasten 12 angeordnet, der an seiner Oberseite 13 offen ist, d.h. mindestens eine Öffiung 14 (Fig. 2) aufweist Der Saugkasten 12 weist Seitenwände 15,16 auf, die den Umlenkrollen 7, 8 benachbart sind. Die Seitenwände 15, 16 sind so gekrümmt, daßsie dem Umfang der Umlenkrollen 7, 8 folgen. Dadurch ist es möglich, die Oberseite 13 und damit die Öffnung 14 möglichst großzu machen. Die Öffnung 14 kann dadurch fast die gesamte Länge des oberen Trums 10 in Umlaufrichtung abdecken.Between the two pulleys 7, 8 and below the upper run 10 of the Band 6 is arranged a suction box 12 which is open at its upper side 13, i. at least one Öffiung 14 (Fig. 2) The suction box 12 has side walls 15,16 on which the pulleys 7, 8 are adjacent. The side walls 15, 16 are so curved so that they follow the circumference of the pulleys 7, 8. This makes it possible make the top 13 and thus the opening 14 as großzu. The opening 14 can thereby cover almost the entire length of the upper run 10 in the circumferential direction.

Der Saugkasten 12 weist an einer Stimseite einen Anschlußstutzen 19 auf, der mit einer Saugleitung verbunden werden kann. Dementsprechend wird fortlaufend Luft durch die Öffnung 14 abgesaugtThe suction box 12 has on a front end on a connection piece 19 which with a suction line can be connected. Accordingly, air is continuously sucked through the opening 14

Wie insbesondere aus Fig. 2 zu erkennen ist, sind neben dem Band 6 weitere Bänder 6a-6e angeordnet, die ebenfalls um die beiden Umlenkrollen 7, 8 verlaufen. Jedes Band 6, 6a-6e hat eine Erstreckung in Axialrichtung (bezogen auf die Umlenkrollen 7, 8) von etwa 200 mm. Zwischen benachbarten Bändern 6,6a-6e ist ein Abstand 17 vorhanden, der etwa 5 bis 20 mm beträgt.As can be seen in particular from Fig. 2, in addition to the band 6 more bands 6a-6e arranged, which also extend around the two pulleys 7, 8. each Band 6, 6a-6e has an extension in the axial direction (relative to the deflection rollers 7, 8) of about 200 mm. Between adjacent bands 6, 6a-6e is a distance 17 present, which is about 5 to 20 mm.

Die Bänder 6, 6a-6e sind flächig perforiert, d.h. sie weisen eine Vielzahl von Durchgangsöffnungen 18 auf, durch die Luft und auch Staub treten kann.The bands 6, 6a-6e are perforated flat, i. they have a multiplicity of passage openings 18 on, through the air and dust can occur.

Dieser Staub entsteht beim Wickeln. Ursächlich hierfür sind möglicherweise Mikrofriktionen zwischen der Wickelrolle 3 und den Bändem 6, 6a-6e. Der Staub schlägt sich unkontrolliert auf der Wickeleinrichtung 1 nieder, was schon an sich nachteilig ist. Darüber hinaus würde er ohne zusätzliche Maßnahmewischen die einzelnen Lagen der Papierbahn auf der Wickelrolle 3 gelangen, was beim nachfolgenden Bedrucken zu erheblichen Problemen führen kann. Wenn man nun die Bahnen 6, 6a-6e perforiert, wie dargestellt, und gleichzeitig den Saugkasten 12 unter Unterdruck setzt, dann kann man den Staub durch die Bänder 6, 6a-6e und durch die Abstände 17 zwischen den Bändem absaugen. Man verhindert dadurch nicht nur, daß sich der Staub in der Umgebung der Rollenwickeleinrichtung 1 ausbreitet. Man verhindert auch, daß der Staub mit eingewickelt wird. Die Papierbahn 2 bleibt "sauberer" und kann später besser bedruckt werden, weil der Staub das Drucken nicht behindert.This dust is created during winding. This may be due to microfriactions between the winding roll 3 and the bands 6, 6a-6e. The dust is beating uncontrolled on the winding device 1 down, which is disadvantageous in itself. In addition, he would without any additional measures between the individual layers get the paper web on the winding roll 3, resulting in the subsequent printing can lead to significant problems. Now if you perforate the webs 6, 6a-6e, as shown, and at the same time sets the suction box 12 under negative pressure, then you can see the dust through the bands 6, 6a-6e and by the distances 17 between aspirate the tape. It prevents not only that the dust in the Surrounding the reel winder 1 spreads. It also prevents the Dust is wrapped up with. The paper web 2 remains "cleaner" and can later better be printed because the dust does not hinder printing.

Der zum Absaugen des Staubs erforderliche Unterdruck ist relativ klein. Er muß nicht einmal so groß sein, wie ein Druck, der zum Festhalten eines Bahnanfangs benötigt wird, wenn man den Bahnanfang mit Hilfe einer Saugwalze in das Wickelbett zwischen den beiden Stützelementen 5, 9 transportieren will. Erforderlich ist lediglich ein Unterdruck, der in der Lage ist, Staubpartikel abzutransportieren. Da diese Staubpartikel praktisch im Moment ihrer Entstehung abgesaugt werden, haben sie sich noch nicht an anderen Teilen festgesetzt, so daß im Grunde keine höhere Saugkraft erforderlich ist. Dies gilt insbesondere dann, wenn sich das obere Trum 10 des Bandes 6 vom ersten Stützelement 5 weg bewegt und die Bahn 2 oben über das erste Stützelement 5 zugeführt wird. In diesem Fall entsteht der Staub hauptsächlich am Ausgang eines Auflagenips 19 zwischen der Wickelrolle 3 und dem oberen Trum 10. Dort wird der Staub aber unmittelbar wieder entfernt.The vacuum required to extract the dust is relatively small. He does not have to once as large as a pressure needed to hold on to a web start is, if you start the web with the help of a suction roller in the winding bed between wants to transport the two support elements 5, 9. Required is only one Underpressure capable of removing dust particles. Because these dust particles They are sucked off practically at the moment of their formation not fixed to other parts, so that basically no higher suction required is. This is especially true when the upper run 10 of the belt 6 moved away from the first support member 5 and the web 2 above the first support member 5 is supplied. In this case, the dust is mainly produced at the exit a Auflagenips 19 between the winding roll 3 and the upper run 10. There is the dust but immediately removed.
