Description

B E S C H R E I B U N G DESCRIPTION
Wickelmaschine zum Aufwickeln einer Materialbahn, insbesondere einer Papier- oder Kartonbahn zu einer WickelrolleWinding machine for winding a material web, in particular a paper or cardboard web, into a winding roll
Technisches GebietTechnical field
Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln einer Materialbahn, insbesondere einer Papier- oder Kartonbahn, zu einer Wickelrolle gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a winding machine for winding up a material web, in particular a paper or cardboard web, to form a winding roll according to the preamble of patent claim 1.
Zur Herstellung von Wickelrollen aus durch Längsschneiden in Einzelbahnen unterteilten Papier- oder Kartonbahnen sind verschiedene Typen von Wickelmaschinen bekannt.Various types of winding machines are known for producing winding rolls from paper or cardboard webs which are divided into longitudinal webs by longitudinal cutting.
Bei sogenannten Tragwalzen-Wickelmaschinen bilden zwei angetriebene Tragwalzen ein Walzenbett, in dem die Wickelrollen mit fluchtenden Achsen aufgereiht auf den Tragwalzen aufliegen, die somit das gesamte Wickelrollengewicht tragen (DE 43 34 029- A). Die für die Qualität der Wickelrollen entscheidende Wickelhärte (= Flächenpressung zwischen den Lagen einer Wickelrolle) ist entscheidend von der Zugspannung abhängig, mit der die äußerste Lage aufgewickelt wird. Diese Zugspannung beim Aufwickeln wird von den angetriebenen Tragwalzen erzeugt und entscheidend von der Linienlast und den geometrischen Verhältnissen im Nip zwischen einer Wickelrolle und einer Tragwalzen beeinflußt, da im Nip eine zusätzliche Dehnung der Bahn erzeugt wird. Als Linienlast wird die auf die Wickelroilenbreite normierte Anpreßkraft der Wickelrollen, gemessen in N/m, bezeichnet. Da die Dehnung im Nip mit wachsendem Rollengewicht ansteigt, begrenzt ihr Wert den maximalen Enddurchmesser einer fehlerfrei mit der gewünschten Wickelhärte gewickelten Wickelrolle.In so-called carrier roller winding machines, two driven carrier rollers form a roller bed, in which the winding rollers with aligned axes rest on the carrier rollers, which thus carry the entire winding roller weight (DE 43 34 029-A). The winding hardness (= surface pressure between the layers of a winding roller), which is decisive for the quality of the winding rolls, is crucially dependent on the tension with which the outermost layer is wound up. This tension during winding is generated by the driven support rollers and is decisively influenced by the line load and the geometric conditions in the nip between a winding roller and a support roller, since an additional stretch of the web is generated in the nip. The line load is the contact pressure of the winding rolls standardized to the winding roll width, measured in N / m. Since the elongation in the nip increases with increasing roll weight, its value limits the maximum final diameter of a winding roll wound correctly with the desired winding hardness.
Um die für die Wickelqualität entscheidende Linienlast an der Auflagelinie zu der das Rollengewicht tragenden Walze in einem gewünscht niedrigen Bereich halten zu können, sind bei sogenannten Stützwalzen-Rollmaschinen an beiden Seiten einer zentralen Stützwalze aus jeweils zwei Tragelementen bestehende Wickelstationen angeordnet, denen die Einzelbahnen wechselweise zum Aufwickeln zugeführt werden. Jede Wickelstation hält eine Wickelrolle mittels an dem Tragelement drehbar gelagerten Führungsköpfen, die seitlich in die Wickelhülse einfahren. Die Führungsköpfe tragen dabei ganz oder teilweise das Wickelrollengewicht. Der restliche Anteil des Wickelrollengewichts - der gegen Null gehen kann - wird von der Stützwalze getragen. Derartige Stützwalzen-Wickelmaschinen ermöglichen es, Wickelrollen mit großem Durchmesser und/oder aus sehr empfindlichen Papieren mit der gewünschten Qualität herzustellen (DE 40 12 979-A1).In order to be able to keep the line load, which is decisive for the winding quality, on the support line to the roller supporting the roller weight in a desired low range, there are one on both sides in so-called backup roller rolling machines central support roller arranged from two support elements each winding stations, to which the individual webs are alternately fed for winding. Each winding station holds a winding roll by means of guide heads which are rotatably mounted on the support element and which move laterally into the winding tube. The guide heads bear all or part of the winding roll weight. The remaining part of the winding roll weight - which can go to zero - is borne by the backup roller. Back-up roll winding machines of this type make it possible to produce winding rolls of large diameter and / or from very sensitive papers of the desired quality (DE 40 12 979-A1).
Die Stützwalze bei Stützwalzen-Wickelmaschinen und eine der Tragwalzen bei Tragwalzen-Wickelmaschinen dienen zugleich als Kontaktwalze, die mit der Wickelrolle einen Walzennip bilden, in dem die Bahn der Wickelrolle zugeführt wird. Als Kontaktwalze haben sie zugleich die Funktion, den Einzug von Luft in die Wickelrolle zu verhindern, also die Wickelrolle über ihre Breite abzudichten.The support roller in support roller winding machines and one of the support rollers in support roller winding machines also serve as a contact roller, which form a roller nip with the winding roller, in which the web is fed to the winding roller. As a contact roller, they also have the function of preventing air from entering the winding roll, i.e. sealing the winding roll across its width.
Die für die Wickelhärte erforderliche Zugspannung in der Bahn wird bei Tragwalzen- Wickelmaschinen von den als Umfangsantrieb wirkenden Tragwalzen erzeugt, die dazu jeweils mit einem Drehantrieb verbunden sind. Bei Stützwalzen-Wickelmaschinen wirkt die angetriebene Stützwalze ebenfalls als Umfangsantrieb. Um die Härte der Wicklung, insbesondere im Bereich geringer Wickelrollendurchmesser, zusätzlich beeinflussen zu können, ist es bekannt, die Führungsköpfe mit Drehantrieben auszustatten. Über die als Zentrums- oder Kernantrieb arbeitenden Drehantriebe der Führungsköpfe läßt sich so ein zusätzliches Drehmoment zur Beeinflussung der Zugspannung an jeder Wickelrolle erzeugen.The tensile stress in the web required for the winding hardness is generated in the case of carrier roller winding machines by the carrier rollers which act as peripheral drives and which are each connected to a rotary drive for this purpose. In backup roller winding machines, the driven backup roller also acts as a peripheral drive. In order to be able to additionally influence the hardness of the winding, in particular in the area of small winding roll diameters, it is known to equip the guide heads with rotary drives. Additional torque to influence the tension on each winding reel can thus be generated via the rotary drives of the guide heads, which act as a center or core drive.
Stand der TechnikState of the art
Aus der WO 97/28075 ist eine Tragwalzen-Wickelmaschine mit zwei permanent beim Wickeln angetriebenen Tragwalzen bekannt, bei der eine der Tragwalzen einen Mantel aus einer verformbaren Schicht hat, die aus einem zelligen Kunststoffmaterial mit einer Vielzahl von gleichmäßig verteilten Poren besteht und daß ein Kompressionsmodul K von weniger als 10 MPa aufweist. Die volumenkompressible Mantelschicht verringert die nipinduzierte Dehnung der äußersten Lage der Wickelrolle im Walzennip zur Tragwalze. Es wird so das Aufwickeln von Wickelrollen mit größerem Enddurchmesser ermöglicht, ohne daß die Papier- oder Kartonbahn beschädigt wird oder in der Wickelrolle Wickelfehler auftreten. In der WO 93/15007 ist beschrieben, daß bei großen Wickelrollen (Rollenbreite mehr als 2 m, Rollendurchmesser mehr als 1000 mm) gehäuft Platzstellen und Kreppfalten im Bereich des Rollenkerns auftreten, falls das an den Führungsköpfen lastende Rollenge- wicht zu groß wird. Es wird daher bei einer Stützwalzen-Wickelmaschine vorgeschlagen, spätestens ab einem Wickelrollendurchmesser von 1000 mm die Wickeirollen unterhalb ihres Schwerpunkts zusätzlich mittels eines durch Druckluft erzeugten Überdrucks zu unterstützen.From WO 97/28075 a carrier roller winding machine with two carrier rollers permanently driven during winding is known, in which one of the carrier rollers has a jacket made of a deformable layer, which consists of a cellular plastic material with a multiplicity of uniformly distributed pores, and that a compression module K of less than 10 MPa. The volume-compressible jacket layer reduces the nip-induced stretching of the outermost layer of the winding roll in the roller nip to the support roller. It is thus possible to wind winding rolls with a larger final diameter without the paper or cardboard web being damaged or winding errors occurring in the winding roll. In WO 93/15007 it is described that in the case of large winding rolls (roll width more than 2 m, roll diameter more than 1000 mm) there are frequent places and crepe folds in the area of the roll core if the roll weight on the guide heads becomes too large. It is therefore proposed in a backup roller winding machine to support the winding rollers below their center of gravity additionally by means of an excess pressure generated by compressed air, at the latest from a winding roller diameter of 1000 mm.

Darstellung der ErfindungPresentation of the invention
Bei allen bekannten Wickelmaschinen haben die nicht primär für die Erzeugung der gewünschten Wickelhärte notwendigen Elemente zum Halten der Wickelrollen, zur Abstützung des Rollengewichts, zur Vermeidung von Rollenfehlern etc. zugleich einen erheblichen Einfluß auf die für die Qualität der Wickelrollen entscheidende Wickelhärte, oder sie sind konstruktiv sehr aufwendig.In all known winding machines, the elements that are not primarily required for generating the desired winding hardness for holding the winding rolls, for supporting the roll weight, for avoiding roll errors, etc., at the same time have a considerable influence on the winding hardness, which is decisive for the quality of the winding rolls, or they are constructive very complex.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Wickelmaschine zu schaffen, bei der ohne großen konstruktiven Aufwand auch schwere Wickelrollen aus empfindlichen Papieren mit hoher Wickelqualität und -geschwindigkeit aufgewickelt werden können.The object of the invention is therefore to create a winding machine in which even heavy winding rolls made of sensitive papers can be wound up with high winding quality and speed without great design effort.
Diese Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of patent claim 1.
Bei der Wickelmaschine nach der Erfindung übernimmt eine Unterstützungsrolle die sekundären Aufgaben wie Halten der Wickelrollen und/oder Aufnahme des Wickelrollengewichtes, ohne daß von ihr die Wickelhärte merklich beeinflußt wird. Falls sie einen Antrieb aufweist, dient dieser nur dazu, sie auf eine zur Wickelrolle synchrone Umfangsgeschwindigkeit zu beschleunigen und/oder im Kernbereich eine harte Anwicklung zu erzielen. Der Antrieb ist dann abkuppelbar, um die Unterstützungswalze auf Freilauf zu schalten, damit beim Aufwickeln außerhalb des Kernbereichs kein die Wickelhärte beeinflussendes Drehmoment erzeugt wird. Die an der Wickelrolle anliegende Kontaktwalze kann so ausgestaltet werden, daß sie auf ihre wichtigste Funktion, nämlich die Bahn auf die Wickelrolle zu führen, und das Einwickeln von Luft in die Wickelrolle zu verhindern, beschränkt werden kann. Die für die gewünschte Wickelhärte erforderliche Zugspannung der Bahn beim Aufwickeln kann mittels eines Umfangs- und/oder mittels eines Zentrums-/Kernantriebs erzeugt werden, bei dessen Gestaltung die für das Wickeln sekundären Aufgaben (Halten der Wickelrollen, Gewichtsaufnahme) nicht berücksichtigt werden brauchen. Dies schließt natürlich nicht aus, daß in Abhängigkeit von der aufzuwickelnden Papier- oder Kartonsorte, dem Enddurchmesser der Wickelrollen und der erforderlichen Wickelqualität die Kontaktwalze zusätzliche Funktionen übernehmen kann; inbesondere als Umfangsantrieb zu arbeiten und/oder einen Teil des Wickelrollengewichts aufzunehmen.In the winding machine according to the invention, a support role takes on the secondary tasks such as holding the winding rolls and / or taking up the winding roll weight without the winding hardness being noticeably influenced by it. If it has a drive, it only serves to accelerate it to a peripheral speed synchronous with the winding roll and / or to achieve a hard winding in the core area. The drive can then be uncoupled in order to switch the support roller to freewheel so that no torque influencing the winding hardness is generated when winding outside the core area. The contact roller resting on the winding roller can be designed in such a way that it can be limited to its most important function, namely to guide the web onto the winding roller and to prevent the wrapping of air in the winding roller. The tension of the web required for the desired winding hardness during winding can be generated by means of a circumferential and / or by means of a center / core drive, the design of which does not take into account the secondary tasks for winding (holding the winding rollers, weight absorption). Of course, this does not exclude that, depending on the type of paper or cardboard to be wound up, the final diameter of the winding rolls and the required winding quality, the contact roll can take on additional functions; in particular to work as a peripheral drive and / or to take up a part of the winding roll weight.
Tragwalzen-Wickelmaschinen mit einer als Unterstützungswalze nach der Erfindung gestalteten zweiten Tragwalze haben den weiteren Vorteil, daß sie in der Lage sind, auch empfindliche Papiersorten mit hohen Produktionsgeschwindigkeiten aufwickeln zu können. Bei empfindlichen Papiersorten mit hohen Reibkoeffizienten zwischen den Lagen, die keine Lagenverschiebung zwischen der äußeren Lage und den inneren Lagen einer Wickelrolle zulassen, treten von der Wickelgeschwindigkeit abhängige Vibrationen auf. Die Vibrationen werden von der Differenzgeschwindigkeit zwischen den beiden angetriebenen Tragwalzen ausgelöst und begrenzen die Produktionsgeschwindigkeit auf sehr niedrige Werte.Carrier roller winding machines with a second carrier roller designed as a support roller according to the invention have the further advantage that they are able to wind even sensitive types of paper at high production speeds. Vibrations dependent on the winding speed occur with sensitive paper types with high friction coefficients between the layers, which do not allow a layer shift between the outer layer and the inner layers of a winding roll. The vibrations are triggered by the differential speed between the two driven carrier rollers and limit the production speed to very low values.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Bei der in den Figuren 1 und 2 dargestellten Stützwalzen-Wickelmaschine wird die mehrere Meter breite Papier- oder Kartonbahn 1 von einer Vorratsrolle abgezogen, mittels einer Längsschneideeinrichtung 2 in Einzelbahnen aufgeteilt und anschließend zu Wickelrollen 3 aufgewickelt. Die Wickelrollen 3 sind in zwei Wickellinien zu beiden Seiten der Scheitellinie einer angetriebenen, aus Stahl gefertigten Stützwalze 4 von z. B. 1500 mm Durchmesser angeordnet, an der sie während des Aufwickeins anliegen und von der die Rollengewichte ganz oder teilweise getragen werden. Jede Wickelrolle 3 wird jeweils von zwei beidseits in ihre Wickelhülse eingefahrenen, drehbar gelagerten Führungsköp- fen 5 gehalten, die an Schlitten 6 befestigt sind. Die Schlitten 6 sind jeweils mittels einer Kolben-Zylinder-Einheit 7 in etwa radial zur Stützwalze 4 verfahrbar an Tragelementen 8 gelagert. Jeweils zwei quer zur Laufrichtung der Bahn 1 zur Anpassung an verschiedene Bahnbreiten verfahrbare Tragelemente 8 bilden eine Wickelstation, in der eine Wickelrolle 3 aufgewickelt wird.In the support roller winding machine shown in FIGS. 1 and 2, the paper or cardboard web 1, which is several meters wide, is drawn off from a supply roll, divided into individual webs by means of a slitter 2 and then wound up into winding rolls 3. The winding rolls 3 are in two winding lines on both sides of the apex line of a driven, made of steel support roller 4 of z. B. 1500 mm in diameter, to which they rest during winding and from which the roll weights are carried in whole or in part. Each winding roll 3 is held in each case by two rotatably mounted guide heads 5 which are inserted into its winding tube on both sides and are fastened to carriages 6. The carriages 6 are each mounted on support elements 8 by means of a piston-cylinder unit 7 which can be moved approximately radially to the support roller 4. Two supporting elements 8, which can be moved transversely to the running direction of the web 1 to adapt to different web widths, form a winding station in which a winding roll 3 is wound.
Die Stützwaize dient als Kontaktwalze, an der die Wickelrollen 3 beim Aufwickeln unter Druck anliegen. Sie bildet mit jeder Wickelrolle 3 einen Walzennip, in dem jede Einzelbahn 1 der zugehörigen Wickelrolle zugeführt wird. Zugleich dichtet die Stützwalze 4 jede Wickelrolle 3 ab, um das Einwickeln von Luft zu verhindern. Eine Stützwalze 4 als Kontaktwalze hat die zusätzliche Funktion, als Umfangsantrieb zu arbeiten, also die Wickelrollen 3 beim Aufwickeln zu drehen und die für die Wickelhärte erforderliche Zugspannung zu erzeugen. Um die Härte der Wicklung, insbesondere im Kernbereich einer Wickelrolle 3, zusätzlich beeinflussen zu können, sind an dem Schlitten 6 zusätzlich Drehantriebe 9 für die Führungsköpfe 5 befestigt. Bei verschiedenen Papiersorten kann der gewünschte radiale Verlauf der Wickelhärte ohne die zusätzlichen Drehantriebe 9 erreicht werden, dann werden frei drehbar gelagerte Führungsköpfe 5 ohne Drehantriebe 9 verwendet.The support roller serves as a contact roller on which the winding rollers 3 rest under pressure during winding. It forms a roll nip with each winding roll 3, in which each individual web 1 is fed to the associated winding roll. At the same time, the support roller 4 seals each winding roll 3 in order to prevent the wrapping of air. A support roller 4 as a contact roller has the additional function of working as a circumferential drive, that is to say rotating the winding rollers 3 during winding and generating the tensile stress required for the winding hardness. In order to be able to additionally influence the hardness of the winding, in particular in the core region of a winding roller 3, rotary drives 9 for the guide heads 5 are additionally fastened to the carriage 6. In the case of different types of paper, the desired radial course of the winding hardness can be achieved without the additional rotary drives 9, then freely rotatably mounted guide heads 5 without rotary drives 9 are used.
Mit Abstand neben der Stützwalze 4 ist an jeder Seite im Gestell 10 der Wickelmaschine eine Quertraverse 11 angeordnet, die mittels einer Kolben-Zylinder-Einheit 12 heb- und senkbar ist. An den Quertraversen 11 ist für jede Wickelstation ein Schlitten 12 quer zur Bahn 1 verfahrbar gelagert. An jedem Schlitten 12 ist ein Schwenkarm 13 angelenkt, der an seinem Ende ein Druckrollenpaar 14 trägt, das mittels einer Kolben-Zylinder-Einheit 15 gegen den Umfang einer Wickelrolle 3 anschwenkbar ist, um zu Beginn des Aufwickeins, wenn das Auflagegewicht noch nicht ausreicht, die Linienkraft an der Kontaktlinie der Wickelrolle 3 an der Stützwaize 4 für eine größere Wickelhärte zu steigern. Die Kolben-Zylinder-Einheiten 15 sind in der Lage, die Druckrollen 14 in eine nicht störende Ruheposition hochzuschwenken, wie in den Figuren dargestellt ist. Um eine fertige Wickelrolle 3 aus der Wickelmaschine entfernen zu können, kann die Traverse 11 mit den daran befestigten Druckrollen 14 ausreichend hoch bewegt werden.At a distance from the support roller 4, a crossbar 11 is arranged on each side in the frame 10 of the winding machine and can be raised and lowered by means of a piston-cylinder unit 12. On the crossbeams 11, a slide 12 is mounted so that it can move across the web 1 for each winding station. A pivot arm 13 is articulated on each slide 12, which at its end carries a pair of pressure rollers 14, which can be pivoted by means of a piston-cylinder unit 15 against the circumference of a winding roller 3, in order to start the winding, when the weight is not sufficient, the line force on the contact line of the winding roller 3 on the support roller 4 for a higher winding hardness. The piston-cylinder units 15 are able to pivot the pressure rollers 14 up into a non-disturbing rest position, as shown in the figures. In order to be able to remove a finished winding roll 3 from the winding machine, the crossmember 11 with the pressure rolls 14 attached to it can be moved sufficiently high.
Um das an den Führungsköpfen 5 lastende Rollengewicht begrenzen zu können, sind- an jeder Seite der Wickeimaschine neben der Stützwalze 4 Unterstützungsrollen 16 achsparallel zur Stützwalze 4 angeordnet, die von unten gegen jeweils eine Wickelrolle 3 bewegbar gelagert sind. Jede Unterstützungsrolle 16 besteht aus einem hohlzylinder- förmigen Tragkörper 19 aus einem festen Material, insbesondere aus Stahl, auf dessen äußeren Mantelfläche eine begrenzt verformbare Schicht 20 aus einem zelligenIn order to be able to limit the roll weight on the guide heads 5, 4 support rolls 16 are arranged on each side of the winding machine in addition to the support roll 4, parallel to the support roll 4, which are movably supported from below against a winding roll 3. Each support roller 16 consists of a hollow cylindrical support body 19 made of a solid material, in particular steel, on the outer circumferential surface of which a layer 20 of a cellular form which can be deformed to a limited extent
Kunststoffmaterial mit einer Vielzahl von gleichmäßig verteilten Poren aufgebracht ist. Das aus einem zelligen Elastomer, insbesondere Polyurethan bestehende Kunststoffmaterial weist ein Kompressionsmodul K von weniger als 10 MPa, vorzugsweise zwischen 1 MPa und 5 MPa, auf. Die Größe der Poren beträgt weniger als 5 mm, bevorzugt zwischen 0,05 und 1 mm. Bevorzugt sind die Poren in der verformbaren Schicht teilweise offen - also miteinander verbunden -, teilweise in sich geschlossen. Der Anteil der offenen Poren beträgt 30 % bis 70 %, vorzugsweise ca. 50 %. Das Verhältnis der offenen Poren zu den geschlossenen Poren bestimmt sowohl die Kompressibilität als auch die Fähigkeit der Schicht, im Innern entstehende Wärme abzuleiten, um uner- wünschte Überhitzungen zu vermeiden. Die vorstehend angegebenen Parameter haben sich als besonders geeignet gezeigt.Plastic material with a variety of evenly distributed pores is applied. The plastic material consisting of a cellular elastomer, in particular polyurethane, has a compression modulus K of less than 10 MPa, preferably between 1 MPa and 5 MPa. The size of the pores is less than 5 mm, preferably between 0.05 and 1 mm. The pores in the deformable layer are preferably partially open - that is, connected to one another - and partially closed. The proportion of open pores is 30% to 70%, preferably approximately 50%. The ratio of the open pores to the closed pores determines both the compressibility and the ability of the layer to dissipate heat generated in the interior in order to avoid undesired overheating. The parameters specified above have been shown to be particularly suitable.
Der Durchmesser der Unterstützungsrollen 16 beträgt 300 mm bis 600 mm, vorzugsweise ca. 400 mm, die radial gemessene Dicke der verformbaren Schicht 20 beträgt 10 mm bis 40 mm, vorzugsweise 15 mm bis 25 mm. Bevorzugt ist jedem Druckrollenschlitten 12 eine Unterstützungsrolle 16 zugeordnet, deren axiale Länge der Länge der Druckrollen 14 entspricht; im Beispiel ca. 400 mm. Jede Unterstützungswalze 16 ist an dem zugehörigen Druckwalzenschlitten 12 so gelagert, daß sie von einer nicht dargestellten pneumatischen Kolben-Zylinder-Einheit gegen die Unterseite einer Wickelrolle 3 hochgeschwenkt und mit einer steuerbaren Kraft gegen diese angedrückt werden kann. Die Lagerung an dem Druckrollenschlitten 12 hat den Vorteil, daß die Unterstützungsrollen 16 mit diesen automatisch quer positioniert werden. In der Regel unterstützen mehrere, axial fluchtend nebeneinander positionierte Unterstützungswalzen 16 eine Wickelrolle 3 über deren gesamte axiale Länge, die bis zu 3,5 m betragen kann.The diameter of the support rollers 16 is 300 mm to 600 mm, preferably approximately 400 mm, the radially measured thickness of the deformable layer 20 is 10 mm to 40 mm, preferably 15 mm to 25 mm. A support roller 16 is preferably assigned to each pressure roller carriage 12, the axial length of which corresponds to the length of the pressure rollers 14; 400 mm in the example. Each support roller 16 is mounted on the associated pressure roller carriage 12 so that it can be pivoted up by a pneumatic piston-cylinder unit, not shown, against the underside of a winding roll 3 and pressed against it with a controllable force. The storage on the pressure roller carriage 12 has the advantage that the support rollers 16 are automatically positioned transversely with them. Usually support a plurality of axially aligned support rollers 16 one winding roller 3 over its entire axial length, which can be up to 3.5 m.
Um eine reibungsfreie Anlage an die Wickelrolle 3 während des Aufwickelns zu ermöglichen, ist jede Unterstützungsrolle 16 mit einem zu- und abschaltbaren Drehantrieb verbunden, mit dem ihre Umfangsgeschwindigkeit vor dem Anlegen an eine Wickelrolle 3 mit deren Umfangsgeschwindigkeit synchronisiert werden kann. Anschließend wird der Synchronantrieb abgeschaltet, die Unterstützungsrolle 16 liegt frei drehbar an der zugehörigen Wickelrolle 3 an.In order to enable a frictionless contact with the winding roller 3 during winding, each support roller 16 is connected to a rotary drive which can be switched on and off and with which its peripheral speed can be synchronized with its peripheral speed before being applied to a winding roller 3. Then the synchronous drive is switched off, the support roller 16 is freely rotatable on the associated winding roller 3.
Da zum Entladen einer vollen Wickelrolle 3 die Druckrollentraverse 11 mit den daran befestigten Elementen nach oben bewegt werden muß, kann jede Unterstützungsrolle 16 in eine entsprechende Aussparung der Traverse 1 versenkt werden. Alle Unterstützungsrollen 16 einer Wickellinie werden so mit der Traverse 11 nach oben in eine Position bewegt, bei der unterhalb der Traverse 11 ein ausreichend großer Freiraum vorhanden ist, durch den eine fertig gewickelte Wickelrolle 3 aus der Wickelmaschine bewegt werden kann.Since in order to unload a full winding roll 3, the pressure roll crossmember 11 with the elements attached to it must be moved upward, each support roll 16 can be sunk into a corresponding recess in the crossmember 1. All support rollers 16 of a winding line are thus moved with the crossbar 11 upwards into a position in which there is a sufficiently large free space underneath the crossbar 11, through which a completely wound winding roller 3 can be moved out of the winding machine.
Zu Beginn der Wicklung werden die Traversen 11 in ihre untere Position abgesenkt, und die Druckrollen 14 werden gegen die Wickelrollen 2 bewegt, um die Linienkraft an der Kontaktstelle mit der Stützwalze 4 zu erhöhen. Wenn das Auflagegewicht der Wickelrollen 3 einen gewissen Wert erreicht hat, wird zunächst der weitere Gewichtszuwachs so kompensiert, daß mittels der ziehenden Kolben-Zylinder-Einheiten 7 über die Führungsköpfe 5 eine Entlastungskraft aufgebracht wird. Spätestens ab einem Rollendurchmes- ser von ca. 1000 mm erfolgt eine weitere Entlastung mit den Unterstützungsrollen 16, damit das an den Führungsköpfen 5 lastende Rollengewicht nicht zu groß wird. Die Unterstützungsrollen 16 werden dazu aus ihrer Ruheposition in der Traverse 11 hinausbewegt, auf eine mit den Wickelrollen 3 synchrone Umfangsgeschwindigkeit beschleunigt und anschließend von unten gegen die Wickelrollen 3 gedrückt. Bei wachsendem Durchmesser der Wickelrollen 3 werden die Unterstützungsrollen 16 - wie in Figur 2 gezeigt - nachgeführt, vorzugsweise durch eine kombinierte Schwenk- und Vertikalbewegung. Die letztere Bewegung kann durch eine lineare Vertikalbewegung der Druckrollentraverse 11 bewirkt werden.At the beginning of the winding, the traverses 11 are lowered into their lower position, and the pressure rollers 14 are moved against the winding rollers 2 in order to increase the line force at the point of contact with the support roller 4. When the bearing weight of the winding rolls 3 has reached a certain value, the further weight increase is first compensated for so that a relieving force is applied by means of the pulling piston-cylinder units 7 via the guide heads 5. At least from a roller diameter of approx. 1000 mm, the support rollers 16 provide further relief so that the roller weight on the guide heads 5 does not become too large. For this purpose, the support rollers 16 are moved out of their rest position in the crossmember 11, accelerated to a circumferential speed synchronized with the winding rollers 3, and then pressed against the winding rollers 3 from below. As the diameter of the winding rolls 3 increases, the support rolls 16 - as shown in FIG. 2 - are adjusted, preferably by a combined pivoting and vertical movement. The latter movement can be brought about by a linear vertical movement of the pressure roller crossmember 11.
Die Entlastungskraft der Stützrollen 16 wird über die von unten nach oben drückenden pneumatischen Kolben-Zyiinder-Einheiten so gesteuert, daß die gewünschte Verteilung des Wickelrollengewichts auf die Stützwalze 4, die Unterstützungsrollen 16 und die Führungsköpfe 5 vorliegt. Die Gewichtsverteilung wird durchmesserabhängig gesteuert, um den gewünschten Wickelaufbau zu erreichen.The relief force of the support rollers 16 is controlled by the pneumatic piston-cylinder units pushing upwards in such a way that the desired distribution of the winding roller weight on the support roller 4, the support rollers 16 and the Guide heads 5 is present. The weight distribution is controlled depending on the diameter in order to achieve the desired winding structure.
Nach dem Ende des Aufwickeins werden zunächst die Unterstützungsrollen 16 in die Traversen 11 versenkt. Anschließend wird die Traverse 11 mit den Unterstützungsrollen 16 und den Druckrollen 14 in eine obere Parkposition bewegt, bei der die Wickelrollen 3 aus der Maschine entfernt werden können.After the end of the winding up, the support rollers 16 are first sunk into the crossbeams 11. The traverse 11 with the support rollers 16 and the pressure rollers 14 is then moved into an upper parking position, in which the winding rollers 3 can be removed from the machine.
In den Figuren 3 und 4 ist eine Tragwalzen-Wickelmaschine dargestellt, die als Kontaktwalze eine angetriebene Tragwalze 19 aufweist. Neben dieser ersten Tragwalze 19 ist eine Unterstützungswalze 20 achsparallel angeordnet, die mit der ersten Tragwalze 19 ein Walzenbett bildet, in dem die Wickelrollen 3 beim Aufwickeln auf den Tragwalzen 19, 20 aufliegen. Ebenso wie die erste Tragwalze 19 erstreckt sich die zweite Tragwalze 20 über die gesamte Arbeitsbreite, i. e. die maximale Breite der aufzuwickelnden Papier- oder Kartonbahn 1. Die Papier- oder Kartonbahn 1 wird von einer Längsschneideeinrichtung in Einzelbahnen aufgeteilt, die bei der Ausführungsform nach Figur 3 durch den Spalt zwischen den Tragwalzen 19, 20 in das Walzenbett geführt werden, wo sie auf fluchtend aufgereihte Hülsen 21 gewickelt werden. Oberhalb des Walzenbetts ist im Gestell der Wickelmaschine ein Druckrollensystem angeordnet, das eine freilaufend gelagerte Druckrolle 22 enthält. Zu Beginn der Aufwicklung, wenn das Auflagegewicht der Wickelrollen 3 auf den Tragwalzen 19, 20 für die gewünschte Wickelhärte noch nicht ausreicht, läßt sich mittels der von oben drückenden Druckrolle 22 das Auflagegewicht der Wickelrollen 3 auf den Tragwalzen 1 , 2 erhöhen. An jeder Maschinenseite ist ein Führungskopf vertikal beweglich gelagert, der jeweils von außen in die Hülse 21 der Randrolle einfährt, um den Satz von Wickelrollen 3 beim Aufwickeln seitlich zu führen.FIGS. 3 and 4 show a carrier roller winding machine which has a driven carrier roller 19 as the contact roller. In addition to this first support roller 19, a support roller 20 is arranged axially parallel, which forms a roller bed with the first support roller 19, in which the winding rollers 3 rest on the support rollers 19, 20 during winding. Like the first support roller 19, the second support roller 20 extends over the entire working width, i. e. the maximum width of the paper or cardboard web 1 to be wound up. The paper or cardboard web 1 is divided by a longitudinal cutting device into individual webs which, in the embodiment according to FIG. 3, are guided through the gap between the support rollers 19, 20 into the roller bed, where they open aligned sleeves 21 are wound. Above the roller bed, a pressure roller system is arranged in the frame of the winding machine, which contains a free-running pressure roller 22. At the beginning of the winding, when the bearing weight of the winding rollers 3 on the support rollers 19, 20 is not yet sufficient for the desired winding hardness, the support weight of the winding rollers 3 on the support rollers 1, 2 can be increased by means of the pressure roller 22 pressing from above. On each side of the machine, a guide head is vertically movably mounted, which in each case moves from the outside into the sleeve 21 of the edge roller in order to laterally guide the set of winding rollers 3 during winding.
Die beiden Tragwalzen 19, 20 haben einen Durchmesser von 300 mm bis 1000 mm. Ihre von der Breite der Papier- oder Kartonbahn 1 abhängige axiale Länge kann bis zu 10 m betragen. Die einlaufseitige Tragwalze 19 hat einen Mantel aus Stahl, der mit einer elastisch verformbaren Laufschicht aus einem Vollelastomer, beispielsweise aus Gummi, beschichtet sein kann. Sie hat die primäre Aufgabe, jede Einzelbahn 1 in den mit der jeweiligen Wickelrolle 3 gebildeten Walzennip zu führen und das Einwickeln von Luft in die Wickelrollen 3 zu verhindern. Zusätzlich wird in den Walzennips zwischen der Tragwalze 19 und den Wickelrollen 3 durch nipinduzierte Dehnung die gewünschte Wickelhärte erzeugt. Damit diese Funktion erfüllt werden kann, ist der Belag der Tragwalze 19 nicht volumenkompressibel. Die als Unterstützungswalze dienende zweite Tragwalze 20 besteht aus einem hohlzylinderförmigen Tragkörper 23 aus einem festen Material, insbesondere aus Stahl, auf dessen äußere Mantelfläche eine volumenkompressible Schicht 24 aus einem zelligen Kunststoffmaterial mit einer Vielzahl von gleichmäßig verteilten Poren aufgebracht ist. Die Dicke und Materialeigenschaften der Schicht 24 entsprechen denen der Schicht 20 der Unterstützungsrollen 16 der vorstehend beschriebenen Stützwalzen- Wickelmaschine nach den Figuren 1 und 2. Die zweite Tragwalze 20 ist frei drehbar gelagert oder mit einem Drehantrieb verbunden, der auf Freilauf schaltbar ist. Falls ein Drehantrieb vorhanden ist, dient dieser nur dazu, die Tragwalze 20 beim Anfahren der Wickelmaschine synchron zur Tragwalze 19 zu beschleunigen und/oder im Kernbereich einer Wickelrolle 3 eine harte Anwicklung zu erzielen. Beim Aufwickeln außerhalb des Kernbereichs einer Wickelrolle 3 ist der Drehantrieb abgekuppelt. Die Tragwalze 20 dreht frei, damit kein die Wickelhärte beeinflussendes Drehmoment erzeugt wird. Beim Aufwickeln außerhalb des Kernbereichs einer Wickelrolle dient die Tragwalze 20 ausschließlich dazu, die Wickelrollen 3 in ihrer Wickelposition zu halten und einen Anteil des Wickelrollengewichts zu tragen, ohne daß durch ein Drehmoment oder durch Erzeugung einer nipinduzierten Dehnung Einfluß auf die Wickelhärte genommen wird. Als Unterstützungsrolle ist die Tragwalze 20 relativ zu der als Kontaktwalze dienenden einlaufseitigen Tragwalze 19 so angeordnet, daß von ihr 30 % bis 80 % des Wickelrollengewichts aufgenommen wird. Der Rest des Wickelrollengewichts wird von der Tragwalze 19 getragen.The two support rollers 19, 20 have a diameter of 300 mm to 1000 mm. Their axial length depending on the width of the paper or cardboard web 1 can be up to 10 m. The inlet-side support roller 19 has a jacket made of steel, which can be coated with an elastically deformable running layer made of a solid elastomer, for example made of rubber. It has the primary task of guiding each individual web 1 into the roll nip formed with the respective winding roll 3 and preventing the wrapping of air in the winding rolls 3. In addition, the desired winding hardness is generated in the roller nips between the support roller 19 and the winding rollers 3 by nip-induced stretching. In order for this function to be fulfilled, the covering of the support roller 19 is not volume-compressible. The second support roller 20, which serves as a support roller, consists of a hollow cylindrical support body 23 made of a solid material, in particular steel, on the outer lateral surface of which a volume-compressible layer 24 made of a cellular plastic material with a large number of uniformly distributed pores is applied. The thickness and material properties of the layer 24 correspond to those of the layer 20 of the support rollers 16 of the above-described backup roller winding machine according to FIGS. 1 and 2. The second support roller 20 is freely rotatably mounted or connected to a rotary drive which can be switched to freewheeling. If a rotary drive is present, this only serves to accelerate the support roller 20 when the winding machine starts up, in synchronism with the support roller 19 and / or to achieve a hard winding in the core area of a winding roller 3. When winding outside the core area of a winding roll 3, the rotary drive is uncoupled. The support roller 20 rotates freely so that no torque influencing the winding hardness is generated. When winding outside the core area of a winding roll, the support roller 20 is used only to hold the winding rolls 3 in their winding position and to carry a portion of the winding roll weight without the winding hardness being influenced by a torque or by generating a nip-induced stretch. As a support roller, the support roller 20 is arranged relative to the inlet-side support roller 19 serving as a contact roller in such a way that 30% to 80% of the winding roller weight is absorbed by it. The rest of the winding roll weight is carried by the support roller 19.
Die Druckwalze 22 des Druckwalzensystems weist bevorzugt ebenfalls eine volumen- kompressible Laufschicht mit den Merkmalen der Schicht 24 auf. Sie ist entweder als frei drehbar gelagerte durchgehende Rolle gestaltet oder sie besteht aus einzelnen, frei drehbar gelagerten Rollensegmenten.The pressure roller 22 of the pressure roller system preferably likewise has a volume-compressible running layer with the features of the layer 24. It is either designed as a freely rotatable continuous roller or it consists of individual, freely rotatable roller segments.
In Figur 4 ist eine Tragwalzen-Wickelmaschine dargestellt, bei der die Bahn 1 mit nur geringer Umschlingung der einlaufseitigen Tragwalze 19 von oben den Nips zwischen der Tragwalze 19 und den Wickelrollen 3 zugeführt wird. Die geänderte Bahnzuführung führt dazu, daß die Drehrichtungen der Tragwalzen 19, 20, der Wickelrollen 3 und der Druckrolle 22 gegensinnig zu den Drehrichtungen bei der Tragwalzen-Wickelmaschine nach Figur 3 sind. Ansonsten entspricht der Aufbau dieser Tragwaizen-Wickelmaschine dem Aufbau der vorstehend beschriebenen Tragwalzen-Wickelmaschine nach Figur 3. In Figur 5 ist eine weitere Ausführungsform einer Tragwalzen-Wickelmaschine dargestellt, bei der eine zweite Unterstützungsrolle 25 als dritte Tragwalze neben der als Kontaktwalze dienenden ersten Tragwalze 19 auf der zur zweiten Tragwalze 20 entgegengesetzten Seite angeordnet ist. Der Aufbau der dritten Tragwalze 25 entspricht den der zweiten Tragwalze 20. Sie enthält somit ebenfalls eine Laufschicht 24 aus einem volumenkompressiblen Kunststoffmaterial. Sie ist ebenfalls frei drehbar gelagert oder mit einem abkuppelbaren Drehantrieb verbunden, damit sie auf Freilauf geschaltet werden kann. Die dritte Tragwalze 25 bildet mit der ersten Tragwalze 19 ein zweites Tragwalzenbett, in dem jede zweite Wickelrolle 3 aufgewickelt wird. Die Einzelbahnen 4 werden von unten durch den Spalt zwischen der ersten Tragwalze 19 und einer Unterstützungswalze 20 den beiden Waizenbetten wechselweise zugeführt. Die Wickelrollen 3 von zwei benachbarten Einzelbahnen 4 werden somit jeweils in verschiedenen Walzenbetten gewickelt. Um zu Beginn der Aufwicklung das Auflagegewicht der Wickelrollen 3 jeder Wickellinie erhöhen zu können, enthält das Druckrollensystem zwei frei drehbare Druckrollen 22, 26, die jeweils auf die Scheitellinien der Wickelrollen einer Wickellinie auflegbar sind. Die zweite Druckrolle 26 entspricht dabei in ihrem Aufbau und ihrer Funktion der ersten Druckrolle 22, der beim Ausführungsbeispiel nach Figur 3 beschrieben ist. FIG. 4 shows a support roller winding machine in which the web 1 is fed from above to the nips between the support roller 19 and the winding rollers 3 with only slight wrapping around the input-side support roller 19. The changed web feed means that the directions of rotation of the support rollers 19, 20, the winding rollers 3 and the pressure roller 22 are opposite to the directions of rotation in the support roller winding machine according to FIG. Otherwise, the structure of this carrier roller winding machine corresponds to the structure of the carrier roller winding machine according to FIG. 3 described above. FIG. 5 shows a further embodiment of a support roller winding machine, in which a second support roller 25 as a third support roller is arranged next to the first support roller 19 serving as a contact roller on the side opposite to the second support roller 20. The structure of the third support roller 25 corresponds to that of the second support roller 20. It thus also contains a running layer 24 made of a volume-compressible plastic material. It is also freely rotatable or connected to a disconnectable rotary drive so that it can be switched to freewheel. The third carrier roller 25 forms with the first carrier roller 19 a second carrier roller bed in which every second winding roller 3 is wound. The individual webs 4 are fed alternately from below through the gap between the first support roller 19 and a support roller 20 to the two roller beds. The winding rolls 3 of two adjacent individual webs 4 are thus each wound in different roller beds. In order to be able to increase the support weight of the winding rollers 3 of each winding line at the beginning of the winding, the pressure roller system contains two freely rotatable pressure rollers 22, 26, which can each be placed on the apex lines of the winding rollers of a winding line. The structure and function of the second pressure roller 26 corresponds to that of the first pressure roller 22, which is described in the exemplary embodiment according to FIG. 3.
