    Tragtrommelroller bilden die Schlußgruppe einer Papiermaschine. Sie dienen dem Aufwickeln der fertigen Papierbahn zu einem Wickel. Dabei wird als Wickelkern ein Tambour verwendet. Dieser ist parallel zur Tragtrommel angeordnet und mit seinen Lagerzapfen in den Gabeln zweier schwenkbarer Hebel gelagert, so daß der Tambour um einen Teil des Umfanges der Tragtrommel herum schwenkbar ist. Dabei wird der Tambour meist im oberen Scheitelbereich auf die Tragtrommel aufgesetzt und beim Anwickeln des Bahnanfangs um etwa einen Quadranten der Tragtrommel herum verschwenkt, und zwar im Sinne einer Entfernung von der Papiermaschine. Anschließend wird die Wicklung auf horizontal verlaufender Schiene fortgesetzt, und die Anpressung erfolgt über ein Paar Hebel.Carrier drum rollers form the final group of a paper machine. You serve winding the finished paper web into a roll. It is called Winding core used a drum. This is parallel to the carrier drum arranged and with its bearing pins in the forks of two swiveling Lever mounted so that the drum around part of the circumference of the Carrier drum is pivotable. The drum is usually in the upper The apex area is placed on the carrying drum and when the At the beginning of the path around a quadrant of the carrier drum pivoted, in the sense of a distance from the paper machine. Then the winding is on a horizontal rail continued, and the pressure is applied via a pair of levers.

    Um eine fehlerhafte Wicklung zu verhindern, muß eine bestimmte Wickelhärte in jedem Durchmesserbereich gewährleistet sein, welche durch den Bahnzug und in größerem Maße durch das Anpressen der Rolle an die Tragtrommel erzeugt wird. Bei breiten und schnellaufenden Papiermaschinen mit sehr großen Wickeldurchmessern reichen die vorgenannten Möglichkeiten nicht mehr aus, um Papierfehler wie Falten und Aufplatzungen im Kernbereich der fertigen Rolle zu verhindern. To prevent faulty winding, a certain winding hardness must be used be guaranteed in every diameter range caused by the web train and to a greater extent by pressing the roller onto the carrier drum is produced. For wide and high-speed paper machines with very Large winding diameters do not suffice for the aforementioned options more out to paper errors like creases and splits in the core area of the finished roll to prevent.

    Die Entstehung dieser Fehler ist auf hohe Radialpressung bei ungenügender Tangentialspannung des Papiers mit daraus resultierenden Lageverschiebungen zurückzuführen.The emergence of these errors is due to high radial pressure with insufficient Tangential tension of the paper with resulting Changes in location attributable.

    Um die Wickelhärte zu erhöhen, ist es notwendig, die Tangentialspannung im Wickel zu erhöhen. Zu diesem Zwecke werden Tambourantriebe verwendet, die ein Drehmoment in den Tambour einleiten - sogenannte Zentrumsantriebe. Ein solcher Zentrumsantrieb ist aus Druckschrift (4) bekanntgeworden. Dabei ist es notwendig, zwei Tambourantriebe vorzusehen deren einer auf der Triebseite und deren anderer auf der Führerseite des Tragtrommelrollers angeordnet ist. Hierdurch wird sichergestellt, daß auf den entstehenden Wickel während dessen gesamter Wanderung entlang der Führungsbahn ein Drehmoment aufgebracht wird.To increase the winding hardness, it is necessary to adjust the tangential tension in the Increase wrap. Drum drives are used for this purpose, which introduce a torque into the drum - so-called Center drives. Such a center drive is from document (4) known. It is necessary to provide two reel drives one on the drive side and the other on the driver side of the Carrier drum roller is arranged. This will ensure that emerging wraps during its entire hike along the Guideway a torque is applied.

    Das Vorsehen zweier Antriebe ist mit erheblichem baulichen Aufwand verbunden. Auch kann das genaue zeitliche Einkoppeln des betreffenden Antriebes zu Problemen führen. Deswegen hat der bekannte Tragtrommelroller in der Praxis nicht befriedigt.The provision of two drives is very complex connected. The exact time coupling of the relevant can also Lead to problems. That's why the well-known Carrier drum roller not satisfied in practice.

    Die US-A-3 258 217 bildet den Oberbegriff von Anspruch 1. US-A-3 258 217 zeigt einen Tragtrommelhalter für eine Papiermaschine zum Aufwickeln einer Papierbahn, der zwei Tragtrommeln umfaßt, die beide antreibbar sind.US-A-3 258 217 forms the preamble of claim 1. US-A-3 258 217 shows a support drum holder for a paper machine for winding a Paper web comprising two carrying drums, both of which are drivable.

    Druckschrift (5) zeigt eine zweite Tragtrommel, die dazu dient, während einer verhältnismäßig kurzen Zeitspanne mit dem Papierwickel in Kontakt zu gelangen. Dies findet statt, bevor der Papierwickel von der ersten - eigentlichen - Tragwalze abgefahren wird. Es hat den Zweck, den Zutritt von Luft in die einzelnen Papierlagen auf dem Papierwickel zu verhindern.Document (5) shows a second carrier drum, which is used during a relatively short period of time in contact with the paper wrap reach. This takes place before the paper wrap from the first - actual - carrier roller is moved. It has the purpose of admitting Prevent air in the individual layers of paper on the paper wrap.

    Druckschrift (6) beschreibt eine Wickelmaschine für Kunststoffolien. Dort ist ebenfalls eine zweite Trommel vorhanden, die in vertikaler Richtung verfahrbar ist. Auch Druckschrift (7), die sich auf eine Wickelmaschine für Papierbahnen bezieht, beschreibt die vertikale Verfahrbarkeit einer zweiten Tragtrommel.Document (6) describes a winding machine for plastic films. There is there is also a second drum that can be moved in the vertical direction is. Also publication (7) referring to a winding machine for paper webs refers, describes the vertical travel of a second carrier drum.

    Der Erfindung liegt die Aufgabe zugrunde, einen Tragtrommelroller zur Verfügung zu stellen, bei dem die Wickelhärte vom Anfang bis zum Ende des Wickels den gewünschten Verlauf hat und eine extreme Weichheit im Kernbereich sowie ein plötzlicher Abfall der Härte im mittleren oder äußeren Bereich vermieden wird und sich die Wickelhärte in jedem Augenblick des Wickelvorganges unter Kontrolle befindet; dies soll erreicht werden ohne die Nachteile, die mit einem zweiten Zentrumsantrieb verbunden sind.The invention has for its object to a support drum roller To provide, in which the winding hardness from the beginning to the end of Has the desired course and is extremely soft Core area as well as a sudden drop in hardness in the middle or outer Area is avoided and the winding hardness changes at every moment of the day Winding process is under control; this is to be achieved without the Disadvantages associated with a second center drive.

    Diese Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is achieved by the characterizing features of claim 1 solved.

    Durch die Merkmale von Anspruch 1 wird vor allem erreicht, daß eine höhere Wickeldichte in kontrollierter Weise einstellbar ist. Ein besonderer Vorteil liegt in der Stützwirkung der zweiten Tragwalze während des Wickelns. Durch die Verringerung der Durchbiegung des Tambours infolge der Abstützung auf eine einzige Stützwalze wird ein Kneten und Walken des Tambours im Papierwickel beträchtlich verringert, und es werden Papierschäden im Kern des Papierwickels vermieden.The features of claim 1 primarily achieve that a higher Winding density is adjustable in a controlled manner. There is a particular advantage in the support effect of the second carrier roller during winding. Through the Reduction of the deflection of the drum due to the support a single back-up roll becomes a kneading and milling of the drum in the Paper wrap is significantly reduced and there is paper damage in the core of the paper wrap avoided.

    Die Erfindung ist anhand der Figuren 1-4 näher erläutert. Dabei ist der Aufbau des Tragtrommelrollers bereits sehr gut aus den Figuren 1 und 4 erkennbar. The invention is explained in more detail with reference to FIGS. 1-4. Here is the structure of the carrier drum roller can already be seen very well from FIGS. 1 and 4.

    Die Papierbahn 1 wird über eine Breitstreckwalze 2 auf eine Tragtrommel 3 geführt und mittels eines Tambours 5 zu einem Wickel 4 aufgewickelt. Tambour 5 rollt dabei auf einer horizontalen Führungsbahn 6 ab. Die Anpressung erfolgt über Schlitten 7, die jeweils auf beiden Seiten des Rollers angeordnet sind und mittels Zylindern 8 bewegt werden. Nach Erreichen eines maximalen Wickeldurchmessers wird ein Klemmhebel 9 mittels eines Druckzylinders 10 abgesenkt, so daß der Wickel ausgeworfen werden und Schlitten 7 einen neuen Wickel übernehmen kann. Während des Wickelns werden die Tambourlager 12 zwischen den Hebeln 9 und 11 fest eingespannt. Hebel 11 ist im Gegenzeigersinn schwenkbar, so daß er bei Übernahme eines neuen Tambours unter dem Tambourlager hindurchgleiten kann. Ein Anschlag 13 begrenzt das Wegklappen beim Anpressen.The paper web 1 is spread over a spreader roller 2 Carried drum 3 and by means of a drum 5 to one Coil 4 wound up. Drum 5 rolls on one horizontal guideway 6 from. The pressure is applied via Carriage 7, each on both sides of the scooter are arranged and moved by means of cylinders 8. After A maximum winding diameter is reached Clamping lever 9 lowered by means of a pressure cylinder 10, see above that the wrap are ejected and carriage 7 one can take over new wraps. During the wrapping the drum bearing 12 between the levers 9 and 11 firmly clamped. Lever 11 is pivotable in the counterclockwise direction, so that when he took over a new drum under the Reel bearing can slide through. A stop 13 limits folding away when pressed.

    Ein Leertambour 14 ist in Schwenkhebeln 15 gelagert, die ihrerseits um das Tambourlager 16 schwenkbar sind. Die Schwenkhebel 15 können den Tambour 14 bis auf die Führungsbahn 6 entlang der Umfangslinie der Tragtrommel abschwenken. Hierzu dient ein Druckzylinder 17. Dabei werden die Lager 20 des Tambours 14 mittels Hebeln 18 gehalten, die ihrerseits durch Druckzylinder 19 betätigt werden.An empty reel 14 is mounted in swivel levers 15 which are in turn pivotable about the reel bearing 16. The Swivel lever 15 can the drum 14 up to the Guideway 6 along the circumferential line of the support drum swing away. A pressure cylinder 17 is used for this purpose the bearings 20 of the drum 14 by means of levers 18th held, which in turn operated by pressure cylinder 19 will.

    Eine weitere Tragtrommel 21 befindet sich unterhalb der Führungsbahn 6. Sie ist mit ihren Lagern 22 in Gleitschienen 23 geführt. Es sind Druckzylinder 24 auf beiden Seiten der Maschine vorgesehen, die an den Lagern 22 der zweiten Tragtrommel 21 angreifen und diese gegen den laufenden Wickel 4 andrücken.Another support drum 21 is located below the Guideway 6. It is 22 in with its bearings Slide rails 23 out. There are pressure cylinders 24 on Both sides of the machine provided on the bearings 22nd attack the second support drum 21 and this against the Press on the running winding 4.

    Die Antriebe der Tragtrommeln 3 und 21 sind derart regelbar, daß die gesamte Antriebsleistung willkürlich auf die beiden Tragtrommeln verteilt werden kann, so daß eine der beiden Tragtrommeln im Extremfall Null oder Hundert % der Antriebsleistung übernimmt. Desgleichen ist die gesamte Antriebsleistung zwischen den beiden Tragtrommeln und dem Zentrumsantrieb beliebig aufteilbar.The drives of the carrying drums 3 and 21 are of this type adjustable that the total drive power is arbitrary the two carrying drums can be distributed so that one of the two carrying drums in extreme cases zero or one hundred percent the drive power takes over. The same is the whole Drive power between the two carrying drums and the Center drive can be divided as required.

    Unterhalb des Tragtrommelrollers befindet sich ein Pulper 27. Das Ausschußpapier, das bei Abrissen anfällt, wird über eine Öffnung 28 auf ein Förderband 30 aufgegeben. Eine Schutzvorrichtung 29 sichert die Öffnung.There is a pulper below the carrier drum roller 27. The scrap paper that arises from demolition is over an opening 28 on a conveyor belt 30 is given. A Protective device 29 secures the opening.

    Die Arbeitsweise des Tragtrommelrollers ist am besten aus den Figuren 2 und 3 erkennbar. Ist der maximale Wickeldurchmesser erreicht - siehe Figur 2 -, so wird der Wickel 4 von Tragtrommel 3 auf der Führungsbahn 6 abgefahren. Tragtrommel 21 folgt dabei dem Wickel 4 und hält den Bahnzug dadurch aufrecht, daß sie auf den Wickel 4 an dessen Umfang durch Reibungsmitnahme Drehmoment aufbringt. Gleichzeitig wird Leertambour 14 durch eine Anwurfvorrichtung 31 auf die Geschwindigkeit der Papierbahn 1 gebracht und mittels der Schwenkhebel 15 auf die Führungsbahn 6 abgeschwenkt. Der volle Tambour 5 wird indessen weiter abgefahren, und Tragtrommel 21 wird hierbei weiterhin angehoben, so lange, bis die Mantelfläche von Tragtrommel 21 an der Mantelfläche des Leertambours 14 anliegt. Der Rollenwechsel erfolgt nunmehr mittels eines Blasrohres 35 - siehe Figur 3 - oder durch Schlaufenbildung, ausgelöst durch das Abfahren von Tambour 5 mit Wickel 4 von Tragtrommel 21.The mode of operation of the carrier drum roller is best off Figures 2 and 3 recognizable. Is the maximum Winding diameter reached - see Figure 2 -, the Roll 4 of carrier drum 3 on the guideway 6 crazy. Carrier drum 21 follows the winding 4 and maintains the web train by placing it on the winding 4 on its circumference by drag torque applies. At the same time, empty drum 14 is replaced by a Starting device 31 on the speed of the paper web 1 brought and by means of the pivot lever 15 on the Guideway 6 pivoted. The full drum 5 will meanwhile, further down, and carrier drum 21 is here continue to be raised until the outer surface of Carrying drum 21 on the outer surface of the empty drum 14 is present. The role change now takes place by means of a Blow pipe 35 - see Figure 3 - or through Loop formation triggered by the descent of the reel 5 with roll 4 of carrier drum 21.

    Bei Bedarf kann dem jeweils wickelnden Tambour ein Zentrumsantrieb zugeordnet werden. Dies ist eine weitere Maßnahme zur Verbesserung der Wickelqualität. Dabei kuppelt der Tambourantrieb kurz vor Erreichen des Maximaldurchmessers des Wickels 4 aus und fährt zur Ausgangsposition vor die Tragtrommel, um Tambour 14 von Wickelbeginn an anzutreiben.If necessary, the respective winding drum Center drive can be assigned. This is another one Measure to improve the winding quality. It couples the reel drive shortly before reaching the Maximum diameter of the winding 4 and moves to Starting position in front of the drum, around drum 14 from Start of winding to drive.
