Description

Die Erfindung bezieht sich auf eine Breitstreckwalze für Bahnenwerkstoffe, insbesondere für Textil-, Papier- und Folienbahnen, mit einer Tragachse, auf der ein Breitstreckbelag vorhanden ist, dessen zylindrischer Außenumfang Vorsprünge aufweist, die mit quer zur Tragachse angeordneten und von der Walzenmitte aus zu den Walzenenden geneigten Einschnitten voneinander getrennt sind.The invention relates to an spreader roll for web materials, in particular for textile, paper and film webs, with a support axis on which a spreader covering is present, the cylindrical outer circumference of which has projections which are arranged transversely to the support axis and from the center of the roll to Roll ends inclined cuts are separated from each other.

Um Bahnenwerkstoffe zu Speicher- und Bearbeitungszwecken flach transportieren zu können, werden Breitstreckwalzen verwendet. Diese führen die Bahnenwerkstoffe also derart, daß keine Falten od. dgl. Verwerfungen im Bahnenwerkstoff gebildet werden können, der also völlig glatt bleibt.In order to be able to transport web materials flat for storage and processing purposes, spreader rollers are used. These thus guide the sheet materials in such a way that no folds or the like can be formed in the sheet material, which therefore remains completely smooth.

Bei einer bekannten Breitstreckwalze besteht der Breitstreckbelag aus mehreren, auf die Tragachse aufgeschobenen Hülsenstücken, deren am Außenumfang vorhandene Vorsprünge durch schraubenlinienartige Rillen gebildet sind. Die Rillen sind V-förmig und so angeordnet, daß die Vorsprünge ein hinterschneidungsloses Sägezähnprofil bilden, wobei die der Mitte zugewendete Flanke flacher ist, als die dem Walzenende zugewendete Flanke. Infolgedessen soll der Bahnenwerkstoff von der Walzenmitte aus jeweils zu den Enden hin gestreckt werden. Um dieses Strecken zu den Enden hin zu fördern, wachsen die Steigungen der schraubenlinienförmigen Rillen von der Walzenmitte zu den Walzenenden. Die bekannte Breitstreckwalze hat einen vergleichsweise komplizierten Aufbau. Es ist eine Vielzahl von Hülsenteilen erforderlich, die jeweils unterschiedlich aufgebaut und zusammengebaut sein müssen. Die vergleichsweise scharfen Kanten der Vorsprünge strapazieren den zu fördernden Bahnenwerkstoff.In a known spreader roller, the spreader covering consists of several, up on the support axis pushed sleeve pieces, the projections on the outer circumference are formed by helical grooves. The grooves are V-shaped and arranged so that the projections form an undercut sawtooth profile, the flank facing the center being flatter than the flank facing the roller end. As a result, the web material should be stretched from the middle of the roll to the ends. To promote this stretching towards the ends, the slopes of the helical grooves grow from the center of the roll to the ends of the roll. The known spreader roller has a comparatively complicated structure. A large number of sleeve parts are required, each of which must be constructed and assembled differently. The comparatively sharp edges of the projections strain the web material to be conveyed.

Demgegenüber liegt-der Erfindung die Aufgabe zugrunde, eine Breitstreckwalze der eingangs genannten Art so zu verbessern, daß sie im Aufbau einfacher ist und den Bahnenwerkstoff weniger strapaziert. Insbesondere soll die Zahl der Einzelteile einer Breitstreckwalze auf ein Minimum reduziert werden.In contrast, the object of the invention is to improve a spreader roller of the type mentioned at the outset in such a way that it is simpler in construction and less stressful on the web material. In particular, the number of individual parts of an spreader roller should be reduced to a minimum.

Diese Aufgabe wird dadurch gelöst, daß der aus gummielastischem Werkstoff bestehende Breitstreckbelag hinterschnittene Ringlamellen aufweist.This object is achieved in that the spreader covering made of rubber-elastic material has undercut ring fins.

Für die Erfindung ist von Bedeutung, daß der Breitstreckbelag aus einem gummielastischen Werkstoff besteht. Die Verwendung solchen Werkstoffs ist für Breitstreckwalzen an sich bekannt. Bei diesen bekannten Walzen wird die Breitstreckwirkung jedoch dadurch erzielt, daß die zylindrischen Walzen über ihre gesamte Länge gebogen angeordnet sind, so daß sie ebenfalls einen sehr komplizierten und auch reparaturanfälligen Aufbau aufweisen müssen.It is important for the invention that the spreader covering consists of a rubber-elastic material. The use of such a material is known per se for spreader rolls. With these Known rollers, however, the spreading effect is achieved in that the cylindrical rollers are arranged bent over their entire length, so that they must also have a very complicated and repair-prone structure.

Des weiteren ist für die Erfindung von Bedeutung, daß der Breitstreckbelag hinterschnittene Ringlamellen aufweist. Diese Ringlamellen besitzen eine erhebliche Elastizität quer zur Walzenachse, so daß der Breitstreckbelag durch den auflaufenden Bahnenwerkstoff zur Achse hin zusammengedrückt werden kann. Dabei führen die hinterschnittenen Ringlamellen eine Bewegung mit einer Komponente in Richtung auf die Achsenden aus, woraus sich die Breitstreckwirkung der Walze ergibt.It is also important for the invention that the spreader covering has undercut ring lamellae. These ring lamellae have a considerable elasticity transversely to the roll axis, so that the spreader covering can be compressed towards the axis by the running web material. The undercut ring lamellas perform a movement with one component in the direction of the axis ends, which results in the spreading effect of the roller.

Jede Ringlamelle weist eine zylindrische Außenumfangsfläche als Teil des Außenumfangs des Breitstreckbelags auf. Infolgedessen bilden alle zylindrischen Außenumfangsflächen der Ringlamellen den zylindrischen Außenumfang der Breitstreckwalze. Es erübrigt sich die an sich bekannte schwach tonnenförmige Ausbildung der Breitstreckwalze bzw. deren vorbeschriebene gebogene Anordnung (sogenannte Bananenwalze).Each ring lamella has a cylindrical outer circumferential surface as part of the outer circumference of the spreader covering. As a result, all the cylindrical outer circumferential surfaces of the ring lamellae form the cylindrical outer circumference of the spreader roller. There is no need for the known, weakly barrel-shaped configuration of the spreader roller or the above-described curved arrangement (so-called banana roller).

Die eine Ringlamelle von benachbarten Lamellen trennenden Einschnitte sind einander überlappend parallel geneigt. Hierdurch wird die gleichförmige Ausbildung benachbarter Lamellen erreicht, verbunden mit einer besonders großen Elastizität quer zur Walzenachse. Es ergeben sich Ringlamellen mit parallelogrammförmigem Querschnitt.The incisions separating an annular lamella from adjacent lamellae are inclined parallel to one another in an overlapping manner. In this way, the uniform formation of adjacent lamellae is achieved, combined with a particularly high elasticity transversely to the roller axis. Ring lamellae with a parallelogram cross section result.

In Ausgestaltung der Erfindung ist die Dicke des Breitstreckbelags mindestens gleich dem Durchmesser der Tragachse und/oder die Dicke des genuteten Bereichs des Breitstrecksbelags ist etwa gleich der Dicke dessen ungenuteten Bereichs. Mit diesen vorgenannten Merkmalen kann die Breitstreckwalze so ausgebildet werden, daß ihre Elastizität bzw. die Elastizität ihrer Ringlamellen den jeweils erforderlichen Breitstreckanforderungen unter Beeinflussung der Form der Ringlamellen angepaßt werden kann, ohne daß der Ausgangskörper zur Herstellung der Breitstreckwalze jeweils geändert werden müßte.In an embodiment of the invention, the thickness of the spreader covering is at least equal to the diameter the supporting axis and / or the thickness of the grooved area of the spreader covering is approximately equal to the thickness of the unrooted area. With these aforementioned features, the spreader roll can be designed so that its elasticity or the elasticity of its ring lamellas can be adapted to the spreading requirements required in each case while influencing the shape of the ring lamellas, without the starting body having to be changed in each case for the production of the spreader roll.

Der Breitstrackbelag besteht vorteilhafterweise aus einem Elastomerwerkstoff.The broad track covering advantageously consists of an elastomer material.

Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail using an exemplary embodiment shown in the drawing.

Die Breitstreckwalze 10 besteht aus einer Tragachse 11 und einem Breitstreckbelag 12. Die Tragachse 11 ist zylindrisch ausgebildet und hat abgesetzte Enden 13 zur Lagerung der Walze z. B. in Radialwälzlagern normaler Stehlager.The spreader roller 10 consists of a support shaft 11 and a spreader covering 12. The support shaft 11 is cylindrical and has stepped ends 13 for mounting the roller z. B. in radial roller bearings normal pillow block bearings.

Der Breitstreckbelag 12 besteht beispielsweise aus einem Elastomerwerkstoff, hat also gummielastische Eigenschaften. Der Durchmesser D des Außenumfangs 14 des Breitstreckbelags 12 ist erheblich großer, als der Durchmesser d der Tragachse 11. Die sich daraus ergebende Dicke D' des Breitstrecksbelags 12 ist etwas größer, als der Durchmesser d der Tragachse 11.The spreader covering 12 consists, for example, of an elastomer material, that is to say it has rubber-elastic properties. The diameter D of the outer circumference 14 of the spreader covering 12 is considerably larger than the diameter d of the support axis 11. The resulting thickness D 'of the spreader covering 12 is somewhat larger than the diameter d of the support axis 11.

Der Breitstreckbelag 12 ist gleich lang oder etwas kürzer, als die unabgesetzte Länge der Tragachse 11, wenn eine Berührung zwischen dem Breitstreckenbelag 12 und Bauteilen zur Lagerung der Breitstreckwalze 10 verhindert werden soll.The spreader covering 12 is the same length or a little shorter than the non-offset length of the support shaft 11 if contact between the spreader covering 12 and components for mounting the spreader roller 10 is to be prevented.

Der Außenumfang 14 hat in Abständen angeordnete Einschnitte 15, so daß der Breitstreckbelag 12 einen genuteten Bereich 16 und einen dazwischen und zwischen der Tragachse 11 liegenden ungenuteten Bereich 17 aufweist. Die Dicke des genuteten Bereichs 16 ist etwa gleich der Dicke des ungenuteten Bereichs 17, also etwa D'/2.The outer circumference 14 has incisions 15 arranged at intervals, so that the spreader covering 12 has a grooved area 16 and an un-grooved area 17 lying between and between the support axis 11. The thickness of the grooved area 16 is approximately equal to the thickness of the non-grooved area 17, ie approximately D '/ 2.

Die Einschnitte 15 sind ausgehend vom Mittelbereich 18 der Breitstreckwalze 10 zu den Enden 19 geneigt. Die Einschnitte 15 sind außerdem ringförmig umlaufend ausgebildet, so daß im Querschnitt parallelogrammförmige Ringlamellen 20 entstehen. Diese Ringlamellen 20 sind infolge der geneigt angeordneten Einschnitte 15 hinterschnitten, so daß sie sich infolge 'des gummielastischen Werkstoffs vertikal zur Tragachse '11 biegen können, wenn von einem auflaufenden Bahnenwerkstoff der Druck P auf sie ausgeübt wird.The incisions 15 are inclined to the ends 19 starting from the central region 18 of the spreader roller 10. The incisions 15 are also formed in an annular circumference, so that parallelogram-shaped R inglamellen 20 arise. These ring lamellae 20 are undercut due to the inclined cuts 15, so that they can bend due to the rubber-elastic material vertically to the support axis '11 when the pressure P is exerted on them by a running sheet material.

Der Mittelbereich 18 der Breitstreckwalze 10 weist eine vertikale Ringnut 21 auf, damit sich die beidseitig anschließenden Ringlamellen 20' ebenfalls quer zur Tragachse 11 verformen können. Die diesen Ringlamellen 20' achsendseitig benachbarten Einschnitte 15' sind wegen der Mittelnut 21 entsprechend kürzer gehalten.The central region 18 of the spreader roller 10 has a vertical annular groove 21, so that the annular lamellae 20 'adjoining on both sides can likewise deform transversely to the support axis 11. The incisions 15 'adjacent to these ring lamellae 20' on the axle side are kept correspondingly shorter because of the central groove 21.

Alle Ringlamellen 20, 20' .haben eine zylindrische Außenumfangsfläche .22 und alle zylindrischen Außeriumfangsflächen 22 'bilden den Außenumfang 14 des Breitstreckbelags 12.All ring lamellae 20, 20 ′ have a cylindrical outer circumferential surface 22 and all cylindrical outer circumferential surfaces 22 ′ form the outer circumference 14 of the spreader covering 12.

Wenn ein Bahneriwerkstoff auf den Außenumfang 14 der Breitstreckwalze 10 aufläuft, wird auf jede Ringlamelle 20, 20' eine 'Kraft P ausgeübt. Diese kann entsprechend dem in der Figur dargestellten Kräftedreieck zerlegt werden, so daß ersichtlich ist, daß sich eine auf jede Lamelle 20 horizontal einwirkende Komponente Ph ergibt. Infolgedessen führt jede Ringlamelle 20 eine entsprechend zu den Achsenden 19 hin gerichtete Bewegung aus, die ein Breithalten des Bahnenwerkstoffs bewirkt.When a web material runs onto the outer circumference 14 of the spreader roller 10, a force P is exerted on each ring lamella 20, 20 '. This can ent speaking of the triangle of forces shown in the figure, so that it can be seen that there is a component Ph acting horizontally on each lamella 20. As a result, each annular lamella 20 executes a movement directed towards the axis ends 19, which causes the web material to be kept wide.
