Description

Die Erfindung betrifft eine Vorrichtung zum kontinuierlichen Aufwickeln einer Faserstoffbahn, insbesondere Papier- beispielsweise Tissuebahn, wobei die Bahn über eine Tragtrommel geführt und in weiterer Folge auf einem Tambour aufgewickelt wird, mit einer horizontal verschiebbaren Haltevorrichtung.The invention relates to a device for the continuous winding of a fibrous web, in particular paper, for example tissue web, wherein the web is guided over a carrier drum and subsequently wound on a spool, with a horizontally displaceable holding device.

Solche Vorrichtungen werden z.B. in der WO 99/65806, die als nächstes Stand der Technik angesehen wird, offenbart, sowie in der WO 99/57048 und der DE 90 06 554 U.Such devices are e.g. in WO 99/65806, which is considered as the closest prior art, as well as in WO 99/57048 and DE 90 06 554 U.

Derartige Vorrichtungen sind bei der Herstellung von Papierbahnen seit langem bekannt. Nachteilig bei den bekannten Vorrichtungen ist, dass entweder der Anpressdruck des Tambours an die Tragwalze derart ist, dass der Tambour durch die durch Reibung erzeugte Kraft angetrieben wird, oder wenn ein separater Antrieb des Tambours vorgesehen wird, kann die Anpresskraft nicht exakt eingestellt werden, da zu viele Stellen vorliegen, an denen nicht kalkulierbare Verluste z.B. durch Reibung entstehen. Der vorgegebene Druck, der in den Anpressdruckzylindern eingestellt wird, definiert daher nicht die tatsächliche Anpresskraft zwischen Tragtrommel und Tambour. Speziell bei Tissuepapier mit hohem Volumen ist eine geringe Anpresskraft erwünscht, um das hohe Volumen nicht durch den Anpressdruck wieder zu zerstören. Bei den bisherigen konventionellen Einrichtungen ist die Anpresskraft jedoch nur ungenau einstellbar und die Verluste durch Reibung in den Mechanikteilen liegen bereits über dem erforderlichen Anpressdruck, so dass eine exakte Regelung nicht erfolgen kann. Bei bisherigen Anlagen tritt auch eine Verschmutzung der Führungsprofile auf, was unter anderem zu ruckartigen Bewegungen und damit zu einer fehlerhaften Papierbahn führt.Such devices have long been known in the manufacture of paper webs. A disadvantage of the known devices is that either the contact pressure of the spool on the support roller is such that the spool is driven by the force generated by friction, or if a separate drive of the spool is provided, the contact pressure can not be set exactly there are too many places where non-calculable losses eg caused by friction. The predetermined pressure, which is set in the contact pressure cylinders, therefore, does not define the actual contact force between the carrier drum and drum. Especially with tissue paper with high volume, a low contact pressure is desired in order not to destroy the high volume again by the contact pressure. However, in the previous conventional devices, the contact pressure is only inaccurately adjustable and the losses due to friction in the mechanical parts are already above the required contact pressure, so that an exact control can not be done. In previous systems, contamination of the guide profiles also occurs, which among other things leads to jerky movements and thus to a faulty paper web.

Ziel der Erfindung ist es, eine gleichmäßige Horizontalbewegung der Wickelrolle (Tambour) zu ermöglichen.The aim of the invention is to enable a uniform horizontal movement of the winding roll (spool).

Die Erfindung ist daher dadurch gekennzeichnet, dass die horizontal verschiebbare Haltevorrichtung mit Tragrollen versehen ist, die in Führungsprofilen laufen, wobei die Führungsprofile durch ein vertikal laufendes Band abgedichtet sind. Damit können Verschmutzungen der Führungsprofile und die dadurch entstehende ruckartige Bewegung der Haltevorrichtung vermieden werden.The invention is therefore characterized in that the horizontally displaceable holding device is provided with support rollers which run in guide profiles, wherein the guide profiles by a vertically running Tape are sealed. This contamination of the guide profiles and the resulting jerky movement of the holding device can be avoided.

Eine vorteilhafte Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass das vertikal laufende Band als Endlosband ausgeführt ist und über zwei an den Enden der Führungsprofile vorgesehenen Umlenkrollen verläuft. Damit werden die Reibungsverluste auf ein Minimum gesenkt.An advantageous development of the invention is characterized in that the vertically running belt is designed as an endless belt and extends over two provided at the ends of the guide profiles pulleys. This reduces the friction losses to a minimum.

Eine günstige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass das Endlosband aus Gewebe, Kunststoff oder Stahl besteht. So kann jeweils das geeignete Band ausgewählt werden.A favorable embodiment of the invention is characterized in that the endless belt consists of fabric, plastic or steel. Thus, the appropriate band can be selected in each case.

Eine günstige Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass die Umlenkrollen Trapeznuten zur Führung des Bandes aufweisen, wobei das Endlosband mindestens ein trapezförmiges Führungsprofil aufweist, das in die Trapeznuten der Umlenkrollen eingreift. Damit wird eine sichere Führung des Bandes gewährleistet und eine seitliche Verschiebung verhindert.A favorable development of the invention is characterized in that the deflection rollers have trapezoidal grooves for guiding the band, wherein the endless band has at least one trapezoidal guide profile which engages in the trapezoidal grooves of the deflection rollers. This ensures a secure guidance of the band and prevents lateral displacement.

Eine vorteilhafte Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass zur Führung des Bandes Schlitze vorgesehen sind, die die Bandkanten umschließen. Damit kann zusätzlich eine gute Abdichtung erreicht werden.An advantageous development of the invention is characterized in that slots are provided for guiding the band, which enclose the band edges. This can also be achieved a good seal.

Eine günstige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass der Hohlraum zwischen Führungsprofil und Band durch Druckluft beaufschlagbar ist. Damit ist es möglich, auch kleinste Staubteilchen fernzuhalten.A favorable embodiment of the invention is characterized in that the cavity between the guide profile and band can be acted upon by compressed air. This makes it possible to keep even the smallest dust particles away.

Eine günstige Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass die Haltevorrichtung eine Kraftmesseinrichtung aufweist. Damit kann die Andruckkraft der Wickelrolle an die Tragrolle direkt und exakt gemessen werden.A favorable development of the invention is characterized in that the holding device has a force measuring device. Thus, the pressing force of the winding roll can be measured directly and accurately to the support roller.

Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass die verschiebbare Haltevorrichtung mit Druckzylindern, insbesondere Hydraulikzylindern verbunden ist, wobei die Druckzylinder mit einer Regel- und/oder Steuereinrichtung verbunden sind. So kann immer eine exakte kontinuierliche Bewegung der Haltevorrichtung gewährleistet werden, so dass die Anpresskraft konstant gehalten werden kann.An advantageous embodiment of the invention is characterized in that the displaceable holding device is connected to pressure cylinders, in particular hydraulic cylinders, wherein the pressure cylinders are provided with a control and / or control device are connected. Thus, an exact continuous movement of the holding device can always be ensured, so that the contact force can be kept constant.

Die Erfindung wird nun anhand der Zeichnungen beispielhaft beschrieben, wobei Fig. 1 eine Anlage gemäß der Erfindung, Fig. 2 einen Schnitt gemäß Linie II-II in Fig. 1, Fig. 3 einen Ausschnitt aus Fig. 1, Fig. 4 einen Schnitt gemäß Linie IV-IV in Fig. 1, Fig. 5 einen Schnitt gemäß Linie V-V in Fig. 4, Fig. 6 einen Schnitt gemäß Linie VI-VI in Fig. 4 und Fig. 7 einen Ausschnitt gemäß Kreis VII in Fig. 6 darstellt.The invention will now be described by way of example with reference to the drawings, in which Fig. 1 is a plant according to the invention, Fig. 2 is a section along line II-II in Fig. 1, Fig. 3 is a detail of Fig. 1, Fig. 4 is a section 4 shows a section according to line VV in FIG. 4, FIG. 6 shows a section according to line VI-VI in FIG. 4 and FIG. 7 shows a section according to circle VII in FIG represents.

Anhand von Fig. 1 wird nun die Wirkungsweise der Vorrichtung beschrieben. Die Wickelwelle (Tambour) 1 wird über eine Absenkvorrichtung 2 in den Primärarm 3 eingelegt und hydraulisch senkrecht über der Tragtrommel 4 festgeklemmt. Auf der Führerseite FS ist ein Getriebemotor 6, der auf einer Platte in Achsrichtung verschiebbar angeordnet ist, montiert. Dieser wird mit der Wickelwelle 1 gekuppelt, um diese auf Maschinengeschwindigkeit zu bringen.The mode of operation of the device will now be described with reference to FIG. The winding shaft (drum) 1 is inserted via a lowering device 2 in the primary arm 3 and clamped vertically vertically above the carrier drum 4. On the driver's side FS is a geared motor 6, which is slidably mounted on a plate in the axial direction mounted. This is coupled to the winding shaft 1 to bring them to machine speed.

Der Primärarm 3 wird nun mittels einer Schwenkeinrichtung 7 solange um die Achse der Tragtrommel 4 gedreht, bis die Wickelwelle 1 auf dieser aufsetzt. Dabei übernimmt die Wickelwelle 1 mit Hilfe einer geeigneten Vorrichtung die Papierbahn P in voller Breite und beginnt sie aufzuwickeln und vergrößert dabei ihren Durchmesser. Die erforderliche Anpresskraft zwischen Wickelwelle 1 und Tragtrommel 4 wird über Hydraulikzylinder 8, die mit einer Kraftmesseinrichtung ausgerüstet sind, aufgebracht und geregelt. Dabei wird auch die Kompensation des Gewichtes der Wickelwelle 1 berücksichtigt. Der Primärarm 3 wird nun weiter um die Achse der Tragtrommel 4 geschwenkt bis die Wickelwelle 1 in eine horizontale Lage kommt. Dabei nimmt die Dicke der Papierrolle kontinuierlich bis maximal 350 mm zu. Der äußere Teil des Primärarms 3 bewegt sich dabei teleskopartig nach außen. Er ist auf Rollenlager 9 geführt, um die Reibungseinflüsse auf die Nipkraft möglichst gering zu halten. Der Papierwickel wird auf eine horizontal verschiebbare Haltevorrichtung 11 aufgesetzt und festgeklemmt.The primary arm 3 is then rotated by means of a pivoting device 7 as long as the axis of the carrier drum 4 until the winding shaft 1 touches on this. The winding shaft 1 takes over by means of a suitable device, the paper web P in full width and starts to wind up and thereby increases its diameter. The required contact force between the winding shaft 1 and the carrier drum 4 is applied and controlled by hydraulic cylinders 8, which are equipped with a force measuring device. In this case, the compensation of the weight of the winding shaft 1 is taken into account. The primary arm 3 is now further pivoted about the axis of the carrier drum 4 until the winding shaft 1 comes in a horizontal position. The thickness of the paper roll increases continuously up to a maximum of 350 mm. The outer part of the primary arm 3 moves telescopically outwards. He is led to roller bearings 9 to the To minimize friction effects on the nip force. The paper roll is placed on a horizontally displaceable holding device 11 and clamped.

Fig. 2 zeigt einen Schnitt gemäß Linie II-II in Fig. 1. Die Haltevorrichtung 11 besteht aus einem Aufnahmeteil 12 mit zwei hydraulisch betätigten Klemmhebeln 13, 14 und sitzt auf einer Kraftmesseinrichtung 16 die ihrerseits wieder auf dem Verschiebeteil 17 montiert ist.Fig. 2 shows a section along line II-II in Fig. 1. The holding device 11 consists of a receiving part 12 with two hydraulically operated clamping levers 13, 14 and sits on a force measuring device 16 which in turn is mounted on the sliding part 17.

Die gesamte Einheit wird auch Sekundärarm 30 genannt. Auf der Triebseite TS ist nun ein in Achsrichtung verschiebbarer Getriebemotor 18 mit der Haltevorrichtung 11 verbunden. Sobald der Papierwickel in horizontaler Lage ist, wird dieser Antrieb 18 auf der Triebseite TS an die Wickelwelle 1 angekuppelt und der Antrieb 6 im Primärarm 3 ausgekuppelt. Während des weiteren Wickelvorganges wird über den Sekundärarm 30 die horizontale Nipkraft (Anpresskraft zwischen Tambour 1 und Tragrolle 4) über je einen Hydraulikzylinder 19 auf Führerseite FS und Triebseite TS erzeugt und über die Kraftmesseinrichtungen geregelt.The entire unit is also called secondary arm 30. On the drive side TS now a sliding in the axial direction geared motor 18 is connected to the holding device 11. Once the paper roll is in a horizontal position, this drive 18 is coupled on the drive side TS to the winding shaft 1 and the drive 6 disengaged in the primary arm 3. During the further winding process, the horizontal nip force (contact force between spool 1 and support roller 4) via a respective hydraulic cylinder 19 on the driver side FS and drive side TS generated via the secondary arm 30 and regulated by the force measuring devices.

Während des weiteren Wickelvorganges im Sekundärarm 30 wird im Primärarm 3 die nächste Wickelwelle 1 vorbereitet. Sobald der Papierwickel die gewünschte Größe erreicht hat, wird er von der Tragtrommel 4 weggezogen, die neue Wickelwelle 1 im Primärarm 3 in die Anwickelposition auf die Tragtrommel 4 gesetzt und die volle Papierbahn P übernommen. Nach dem Ausstoßen der fertigen Papierrolle aus dem Sekundärarm 30 bewegt sich dieser wieder zur Tragtrommel 4 und übernimmt dann die neue Wickelwelle 1 aus dem Primärarm 3. Die Kraftmesseinrichtungen 16 sind derart gestaltet, dass sie nur die tatsächlich aufgebrachten Horizontalkräfte im Nip zwischen Tambour 1 und Tragtrommel 4 erfassen. Vertikalkomponenten aus den Antrieben bzw. aus dem sich veränderten Eigengewicht des Papierwickels beeinflussen die Messwerte nicht. Die erfassten Messwertsignale steuern die Bewegung der beiden Hydraulikzylinder 19, sodass dafür gesorgt ist, dass ein absoluter Parallellauf der Sekundärarme 30 auf Führerseite FS und Triebseite TS sowie ein vorgewählter Nipkraftverlauf (konstant oder veränderlich) über den gesamten Wickelvorgang gesichert ist. Der Verschiebeteil 17 des Sekundärarms 30 ist auf horizontal laufenden Tragrollen 21 gelagert, um auch hier die Reibungseinflüsse gering zu halten.During the further winding process in the secondary arm 30, the next winding shaft 1 is prepared in the primary arm 3. Once the paper roll has reached the desired size, it is pulled away from the carrier drum 4, set the new winding shaft 1 in the primary arm 3 in the Anwickelposition on the carrier drum 4 and the full paper web P taken. After ejecting the finished paper roll from the secondary arm 30, this moves back to the carrier drum 4 and then takes over the new winding shaft 1 from the primary arm 3. The force measuring devices 16 are designed such that they only the actually applied horizontal forces in the nip between the drum 1 and carrier drum 4 capture. Vertical components from the drives or from the changed net weight of the paper reel do not influence the measured values. The detected measured value signals control the movement of the two hydraulic cylinders 19, so that it is ensured that an absolute parallel operation the secondary arms 30 on the driver's side FS and drive side TS and a preselected nip force profile (constant or variable) are secured over the entire winding process. The displacement part 17 of the secondary arm 30 is mounted on horizontally running support rollers 21 in order to keep the friction influences low here as well.

Fig. 3 zeigt nun einen Ausschnitt aus Fig. 1, der den Sekundärarm 30 darstellt. Man kann hier einerseits die Tragrolle 4 und Wickelwelle 1 mit einem bereits teilweise aufgewickelten Papierwickel erkennen. Die Anpresskraft A kann über die Kraftmesseinrichtung 16 unabhängig von der Position und verlustfrei gemessen werden, da keine verlustbehafteten Zwischenelemente vorhanden sind. Während des Wickelvorgangs wird der Verschiebeteil 17 des Sekundärarms 30 durch die Hydraulikzylinder 19 verschoben, so dass immer die gleiche Anpresskraft A der Wickelwelle 1 gegen die Tragrolle 4 wirkt. Die jeweilige Position des Sekundärarms 30 wird dabei durch in den Zylindern 19 integrierte Meßsysteme erfasst.FIG. 3 now shows a section of FIG. 1, which represents the secondary arm 30. One can here on the one hand recognize the support roller 4 and winding shaft 1 with an already partially wound paper roll. The contact force A can be measured via the force measuring device 16 regardless of the position and loss-free, since no loss-prone intermediate elements are present. During the winding process, the displacement part 17 of the secondary arm 30 is displaced by the hydraulic cylinder 19, so that always the same contact pressure A of the winding shaft 1 acts against the support roller 4. The respective position of the secondary arm 30 is detected by integrated in the cylinders 19 measuring systems.

Um das Volumen der Papierbahn P nicht zu zerstören werden sehr geringe Anpresskräfte (bis minimal ca. 0,1 N/mm) angewandt. Mittels der Tragrollen 21 kann eine Verschiebung des Verschiebeteils 17 mit geringsten Reibungsverlusten erzielt werden.In order not to destroy the volume of the paper web P, very low contact forces are applied (to a minimum of approximately 0.1 N / mm). By means of the support rollers 21, a displacement of the sliding part 17 can be achieved with the least friction losses.

Diese Tragrollen 21 werden vor Verschmutzung durch eine spezielle Einrichtung geschützt, wie sie aus Fig. 4 (Schnitt IV-IV in Fig. 1) erkennbar ist.These support rollers 21 are protected from contamination by a special device, as can be seen from Fig. 4 (section IV-IV in Fig. 1).

Sie besteht aus zwei Umlenkrollen 22 pro Führungseinheit 26 (insgesamt 8 Umlenkrollen für eine Anlage), wobei eine Rolle 22 spannbar ist. Um die Umlenkrollen 22 läuft ein Endlosband 23 aus Gewebe, Kunststoff oder Stahl. An diesem Band 23 sind die Tragrollen 21 befestigt, wobei hier beispielhaft nur eine Tragrolle 21 dargestellt ist.It consists of two pulleys 22 per guide unit 26 (a total of 8 pulleys for a system), wherein a roller 22 is tensioned. To the pulleys 22 runs an endless belt 23 made of fabric, plastic or steel. At this band 23, the support rollers 21 are fixed, which by way of example only one support roller 21 is shown here.

Fig. 5 zeigt nun einen Schnitt gemäß Linie V-V in Fig. 4, wobei hier der Aufbau der Tragrollen 21 erkennbar ist. Die Tragrollen 21 laufen dabei auf Schienen 27. Auf der Ober- und Unterseite sind die Flächen 28 des Führungsprofils 26 erkennbar. Auch kann man hier das Endlosband 23, an dem die Tragrollen 21 befestigt sind und das auf der anderen Seite ebenfalls dicht an den Wandflächen 28 des Führungsprofils 26 entlang bewegt wird, gut erkennen.FIG. 5 now shows a section according to line VV in FIG. 4, wherein the structure of the carrying rollers 21 can be seen here. The support rollers 21 run on rails 27. On the top and bottom surfaces 28 of the guide profile 26 can be seen. Also you can here the endless belt 23, to the support rollers 21 are fixed and which is also moved on the other side also close to the wall surfaces 28 of the guide profile 26 along, well.

Fig. 6 zeigt nun einen Schnitt gemäß Linie VI-VI in Fig. 4, der durch eine Umlenkwalze 22 gelegt ist. Die Umlenkwalzen 22 sind mit beispielsweise je zwei Trapeznuten versehen, wobei auf dem Endlosband 23 beispielsweise ebenfalls zwei Trapezprofile 24 aufgebracht sind, die in die Nuten der Umlenkrollen 22 eingreifen und damit ein seitliches Verlaufen verhindern. Die Anzahl der Nuten kann je nach Bandbreite variieren.6 now shows a section according to line VI-VI in FIG. 4, which is laid through a deflection roller 22. The guide rollers 22 are provided with, for example, two trapezoidal grooves, wherein on the endless belt 23, for example, two trapezoidal profiles 24 are applied, which engage in the grooves of the guide rollers 22 and thus prevent lateral bleeding. The number of grooves may vary depending on the bandwidth.

Fig. 7 zeigt einen Ausschnitt VII in Fig. 6. Man erkennt hier sehr deutlich seitliche Schlitze 25 an der Wand 28 des Führungsprofils 26 die zur Führung der Bänder 23 sowie zur Abdichtung dienen. Zusätzlich wird der durch diese Vorrichtung geschaffene Hohlraum 29 durch stetiges Einblasen von Druckluft vor Eindringen von Staub geschützt.FIG. 7 shows a section VII in FIG. 6. It can be seen here very clearly lateral slots 25 on the wall 28 of the guide profile 26 which serve to guide the belts 23 and to seal. In addition, the created by this device cavity 29 is protected by continuous injection of compressed air against the ingress of dust.
