Description
Die Erfindung betrifft eine Schärmaschine zum Schären und Aufwinden von Kettfäden, insbesondere von elastischen oder viskosen Kettfäden, mit einem die Kettfäden aufnehmenden Kettbaum bzw. Teil-Kettbaum, der um eine Drehachse rotationsantreibbar gelagert ist und aus einem zylindrischen Spulenkörper mit zwei seitlichen, flanschartigen Kettbaumscheiben besteht, sowie mit einem zwischen die Kettbaumscheiben eingreifenden, die Kettfäden mit einer Andruckkraft gegen den Spulenkörper drückenden Andruckelement, welches aus zwei Andruckwalzen besteht, die um zueinander sowie zu der Drehachse des Kettbaumes parallele Drehachsen derart drehbar gelagert sind, daß sich jede Andruckwalze mit einer Stirnseite in Richtung einer der Kettbaumscheiben erstreckt und sich die beiden Andruckwalzen in einem - in axialer Richtung des Kettbaumes gesehen - mittleren Bereich um eine axiale Länge X ≧ Null überlappen.The invention relates to a warping machine for warping and winding up warp threads, in particular elastic or viscous warp threads, with a warp beam or partial warp beam that receives the warp threads, which is rotatably mounted about an axis of rotation and consists of a cylindrical bobbin with two lateral, flange-like warp beam disks , as well as with a pressure element that engages between the warp beam discs and presses the warp threads against the bobbin with a pressure force, which consists of two pressure rollers that are rotatably mounted about axes of rotation parallel to each other and to the axis of rotation of the warp beam in such a way that each pressure roller has an end face in Extends in the direction of one of the warp beam disks and the two pressure rollers overlap by an axial length X ≧ zero in a central region - seen in the axial direction of the warp beam.
Die US-A-1 498 764 beschreibt eine derartige Schärmaschine, wobei aber die Andruckwalzen auf diametral gegenüberliegenden Seiten des Kettbaums über an Schwenkhebeln gelagerte Lagerrollen (anti friction rolls) gelagert sind, indem sie mit ihren Umfangsflächen an diesen Lagerrollen anliegen und so von diesen in Richtung des Kettbaums bzw. dessen Spulenkörpers angedrückt werden. Diese Lagerung ist konstruktiv sehr aufwendig (außerordentlich viele Lagerstellen). Die Andruckwalzen liegen dabei folglich jeweils "lose" zwischen den Lagerrollen und dem Spulenkörper. In axialer Richtung werden die Andruckwalzen jeweils zwischen einerseits einer der seitlichen Kettbaumscheiben und andererseits einem "fingerartigen" Halteelement gehalten, wodurch aber die Andruckwalzen stets mit zumindest einer Stirnseite an der jeweiligen Kettbaumscheibe und/oder dem Halteelement anliegen. Diese Anlage verursacht aber nachteiligerweise eine hohe Reibung, wodurch die Arbeitsgeschwindigkeit der bekannten Schärmaschine begrenzt ist. Nun sind zwar die Halteelemente in axialer Richtung verstellbar, um eine Anpassung an verschiedene "Spulenbreiten" vornehmen zu können, allerdings kann hierdurch allenfalls ein "axialer Bewegungsspielraum" der Antriebswalzen verändert werden. Die erwähnte Anlagereibung läßt sich jedoch nicht vermeiden. Zur Erzeugung der Anpreßkraft ist hier eine spezielle Hebel/Feder-Anordnung vorgesehen, wodurch erreicht werden soll, daß beide, ja auf gegenüberliegenden Seiten des Kettbaums angeordneten Andruckwalzen mit der gleichen Kraft beaufschlagt werden. Diese bekannte Schärmaschine ist aufgrund ihres konstruktiven Aufbaus somit relativ kompliziert und aufwendig und eignet sich nur für langsame Schärgeschwindigkeiten.US-A-1 498 764 describes such a warping machine, but the pressure rollers are mounted on diametrically opposite sides of the warp beam via anti-friction rollers mounted on pivoting levers, in that their circumferential surfaces rest against these bearing rollers and thus from them Direction of the warp beam or its bobbin are pressed. This storage is structurally very complex (extraordinarily many bearings). The pressure rollers are therefore each "loose" between the bearing rollers and the bobbin. In the axial direction, the pressure rollers are each held between one of the side warp beam disks on the one hand and a "finger-like" holding element on the other hand, but thereby the pressure rollers always rest with at least one end face on the respective warp beam and / or the holding element. However, this system disadvantageously causes high friction, which limits the working speed of the known warping machine. Now the holding elements are adjustable in the axial direction in order to be able to adapt to different "spool widths", but this can at most change the "axial freedom of movement" of the drive rollers. However, the abovementioned friction cannot be avoided. To generate the contact pressure, a special lever / spring arrangement is provided, whereby the aim is to ensure that the same force is applied to both pressure rollers arranged on opposite sides of the warp beam. This known warping machine is therefore relatively complicated and expensive due to its construction and is only suitable for slow warping speeds.
Aus der US-A-1 587 503 ist eine weitere Schärmaschine bekannt, die aber nur in den seitlichen, an die Kettbaumscheiben angrenzenden Bereichen des Kettbaums jeweils eine Andruckwalze aufweist. Im mittleren Bereich wird ein Andrücken der Kettfäden von einer Antriebswalze (tractor drum bewirkt, die zum Antreiben des Kettbaumes durch kraftschlüssige Mitnahme an dem Spulenkörper bzw. den aufgewundenen Fäden anliegt. Diese Konstruktion der Antriebswalzen wäre somit nicht für solche Schärmaschinen geeignet, bei denen der Kettbaum unmittelbar z.B. über eine Welle angetrieben wird. Jede der beiden seitlichen Andruckwalzen ist nur im Bereich einer ihrer Stirnseiten an einem Halter drehbar gelagert, wobei sich die andere Stirnseite in Richtung der jeweiligen Kettbaumscheibe erstreckt. Die Andruckwalzen sind dabei derart axialbeweglich und federbelastet mit dem Halter verbunden, daß sie stets in Anlage an der jeweiligen Kettbaumscheibe gehalten werden. Somit tritt auch hier stets eine nachteilige, die Arbeitsgeschwindigkeit begrenzende Reibung zwischen den Andruckwalzen und den Kettbaumscheiben auf. Die die Andruckwalzen halternden Halter sind als Hebel ausgebildet, die derart schwenkbeweglich an einem ortsfesten Maschinenrahmen gelagert sind, daß die Andruckwalzen in Richtung des Kettbaums mit der Andruckkraft beaufschlagt werden können. Eine Verstellung der Andruckwalzen in axialer Richtung ist hier jedoch nicht vorgesehen, hätte zudem aber auch gar keinen Sinn, weil ja eine Lageveränderung der Halter ohnehin sofort durch die federnde Beweglichkeit der Antriebswalzen "kompensiert" würde. Diese bekannte Schärmaschine kann folglich ausschließlich mit einer ganz bestimmten Kettbaum-Größe (Wickelbreite) arbeiten. Nachteilig ist hierbei zudem, daß über die gesamte Breite des Kettbaums nur eine ungleichmäßige Andruckkraft erreicht werden dürfte, weil ja die Anlagekraft der mittigen Antriebswalze nicht "frei wählbar" ist, da sie ja im wesentlichen von der notwendigen Traktionswirkung (Kraftschluß) bestimmt wird.A further warping machine is known from US-A-1 587 503, but which has a pressure roller only in the lateral regions of the warp beam adjacent to the warp beam disks. In the middle area, the warp threads are pressed on by a drive roller (tractor drum) which, for driving the warp beam, rests on the bobbin or the wound threads by frictional entrainment. This construction of the drive rollers would therefore not be suitable for warping machines in which the warp beam Each of the two side pressure rollers is rotatably mounted on a holder only in the region of one of its end faces, the other end side extending in the direction of the respective warp beam, the pressure rollers being connected to the holder in such a way that they can move axially and are spring-loaded that they are always in plant the respective warp beam can be held. This means that there is always a disadvantageous friction that limits the working speed between the pressure rollers and the warp beam pulleys. The holder holding the pressure rollers are designed as levers, which are pivotably mounted on a stationary machine frame in such a way that the pressure rollers can be acted upon in the direction of the warp beam. However, an adjustment of the pressure rollers in the axial direction is not provided here, but it would also have no sense, because a change in position of the holder would be "compensated" anyway by the resilient mobility of the drive rollers. This known warping machine can therefore only work with a very specific warp beam size (winding width). Another disadvantage is that only an uneven pressure force should be achieved across the entire width of the warp beam, because the contact force of the central drive roller is not "freely selectable", since it is essentially determined by the necessary traction effect (frictional connection).
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ausgehend von diesem Stand der Technik eine gattungsgemäße Schärmaschine zu schaffen, die sich bei einfacher Konstruktion für besonders hohe Arbeitsgeschwindigkeiten und auch für unterschiedliche Kettbaum-Größen und -Ausführungen eignet.The present invention is based on the object, based on this prior art, to provide a generic warping machine which, with a simple construction, is suitable for particularly high working speeds and also for different warp beam sizes and designs.
Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des neuen Anspruchs 1 erreicht. Diese erfindungsgemäße Merkmalskombination trägt in Verbindung mit den Merkmalen des Oberbegriffs dazu bei, daß außerordentlich hohe Arbeitsgeschwindigkeiten erreicht werden können. Dies liegt insbesondere an der erfindungsgemäßen, axialen Verstellmöglichkeit mindestens einer der Andruckwalzen und vorzugsweise beider Andruckwalzen über ihre Tragarme, wodurch nämlich ein Seitenspiel zwischen den Kettbaumscheiben und den Stirnseiten der Andruckwalzen eingestellt und auch stets aufrechterhalten werden kann. Hierdurch wird in diesem Bereich eine Reibung gänzlich vermieden. Zudem ist diese axiale Verstellmöglichkeit auch vorteilhafterweise "mittenunabhängig" - bezogen auf die axiale Länge des Kettbaums. Denn dadurch, daß die jeweils verstellbare Andruckwalze unabhängig von der jeweils anderen Andruckwalze verstellbar ist, kann vorteilhafterweise auch eine Anpassung an unterschiedliche Kettbaum-Arten vorgenommen werden, die sich durch ihre "Axialmitte" - bezogen auf die Anordnung innerhalb der Schärmaschine - voneinander unterscheiden. Dies bedeutet mit anderen Worten, daß erfindungsgemäß eine optimale Einstellung der Andruckwalzen relativ zu den Kettbaumscheiben unabhängig von der Ausgestaltung und Anordnung des Kettbaums möglich ist. Die Lagerung der Andruckwalzen an den Tragarmen und die mittelbare Verstellung der Andruckwalzen über die Tragarme trägt zu einer außerordentlich einfachen Konstruktion bei. Indem beide Tragarme zusammen mit den an diesen gelagerten Andruckwalzen gemeinsam in der zu dem Kettbaum im wesentlichen radialen Richtung linearbeweglich geführt sind, kann auf besonders einfache Weise die Andruckkraft eingestellt werden, die dann auch praktisch "automatisch" für beide Andruckwalzen gleich groß ist. Darüber hinaus ist aufgrund der konstruktiven Ausgestaltung der erfindungsgemäßen Schärmaschine die Andruckkraft auch stets konstant, unabhängig von der Wicklungsdicke. Auch hierdurch sind besonders hohe Produktionsgeschwindigkeiten möglich.According to the invention this is achieved by the characterizing features of the new claim 1. This combination of features according to the invention in conjunction with the features of the preamble contributes to the fact that extremely high working speeds can be achieved. This is due in particular to the possibility of axial adjustment according to the invention of at least one of the pressure rollers and preferably both pressure rollers via their support arms, which means that a side play between the warp beam discs and the end faces of the pressure rollers can be set and always maintained. This completely prevents friction in this area. In addition, this axial adjustment option is also advantageously "independent of the center" - based on the axial length of the warp beam. Because the adjustable pressure roller is adjustable independently of the other pressure roller, it can also be advantageously adapted to different types of warp beam, which differ from one another by their "axial center" - based on the arrangement within the warping machine. In other words, this means that, according to the invention, an optimal adjustment of the pressure rollers relative to the warp beam disks is possible regardless of the configuration and arrangement of the warp beam. The mounting of the pressure rollers on the support arms and the indirect adjustment of the pressure rollers via the support arms contribute to an extremely simple construction. Since both support arms, together with the pressure rollers mounted on them, are guided in a linearly movable manner in the direction essentially radial to the warp beam, the pressure force can be adjusted in a particularly simple manner, which is then practically “automatically” the same for both pressure rollers. In addition, due to the structural design of the warping machine according to the invention, the pressing force is always constant, regardless of the winding thickness. This also makes particularly high production speeds possible.
Weitere vorteilhafte Ausgestaltungsmerkmale der Erfindung sind in den Unteransprüchen und der nachfolgenden Beschreibung enthalten.Further advantageous design features of the invention are contained in the subclaims and the description below.

Die übrige Ausbildung der Schärmaschine ist nicht Gegenstand der vorliegenden Erfindung und wird daher im folgenden nicht näher erläutert.In the drawing, only one warp beam or
Der Kettbaum 2 ist über nicht dargestellte Lagermittel um eine Drehachse 6 (Fig. 1) rotationsantreibbar gelagert und besteht aus einem zylindrischen Spulenkörper 8 mit zwei seitlichen, flanschartigen Kettbaumscheiben 10 (Außenflansche), die starr oder in axialer Richtung verstellbar mit dem Spulenkörper 8 verbunden sein können.The
Das Andruckelement 4 ist in einer zu dem Kettbaum 2 im wesentlichen radialen Richtung beweglich gelagert (Doppelpfeilrichtung 12) und greift zwischen die Kettbaumscheiben ein, um die Kettfäden gegen den Spulenkörper 8 zu drücken, was insbesondere bei elastischen oder viskosen Kettfäden notwendig, aber auch bei anderen Kettfadenmaterialien zweckmäßig ist.The
Erfindungsgemäß ist nun das Andruckelement 4 zweiteilig aus zwei Andruckwalzen 14, 16 ausgebildet. Jede Andruckwalze 14, 16 ist nur im Bereich einer Stirnseite 14a, 16a um eine Drehachse 18 bzw. 20 drehbar gelagert. Die Drehachsen 18, 20 der beiden Andruckwalzen 14, 16 sind dabei zueinander sowie zu der Drehachse 6 des Kettbaumes 2 parallel angeordnet. Die Drehlagerung der Andruckwalzen 14, 16 ist nun erfindungsgemäß derart, daß sich jede Andruckwalze 14, 16 mit ihrer freien Stirnseite 14b, 16b in Richtung einer der Kettbaumscheiben 10 erstreckt und sich die beiden Andruckwalzen 14, 16 in einem in axialer Richtung des Kettbaumes 2 etwa mittleren Bereich um eine axiale Länge X überlappen, wobei X ≧ Null sein soll, um in jedem Fall über die gesamte axiale Länge des Spulenkörpers 8 hinweg die Kettfäden anzudrücken zu können.According to the invention, the

Die Tragarme 26, 28 sind vorzugsweise zueinander parallel angeordnet und jeweils in einer zu ihrer Längserstreckung senkrechten Richtung (Doppelpfeile 22, 24) unabhängig voneinander linearbeweglich geführt.In the particularly advantageous embodiment of the invention shown, the
Für die Führung jedes Tragarmes 26, 28 sind im dargestellten Beispiel zwei parallele Führungswellen 30 (Fig. 1) vorgesehen, auf denen der Tragarm 26, 28 mit entsprechenden Führungsbohrungen 32 (Fig. 2) gleitet. Dabei können die Tragarme 26, 28 manuell und/oder motorisch bewegbar sein, beispielsweise über Gewindespindeln 34, die mit entsprechenden Gewindebohrungen 36 der Tragarme 26, 28 zusammenwirken, d.h. eine Drehung der jeweiligen Gewindespindel 34 in Richtung des Doppelpfeiles 38 in Fig. 1 bewirkt die beschriebene Linearverschiebung des jeweiligen Tragarmes 26 bzw. 28 in Doppelpfeilrichtung 22 bzw. 24.In the example shown, two parallel guide shafts 30 (FIG. 1) are provided for guiding each
Weiterhin ist es besonders vorteilhaft, wenn die Tragarme 26, 28 gemeinsam in der zu dem Kettbaum 2 im wesentlichen radialen Richtung (Doppelpfeil 12) linearbeweglich geführt sind, was im dargestellten Ausführungsbeispiel der Erfindung dadurch erreicht wird, daß die Tragarme 26, 28 an einem gemeinsamen, linearbeweglich geführten Schlitten 40 geführt sind. Die Mittel zur Führung des Schlittens 40 sind nicht dargestellt; es kann sich jedoch hierbei z.B. um herkömmliche Linearführungen, wie Kugelbüchsen o.dgl. handeln. Vorzugsweise ist der Schlitten 40 zusammen mit den Tragarmen 26, 28 sowie den Andruckwalzen 14, 16 pneumatisch oder hydraulisch verstellbar, wobei der pneumatische oder hydraulische Druck vorteilhafterweise einstellbar ist, um hierdurch die Andruckkraft der Andruckwalzen 14, 16 regeln zu können.Furthermore, it is particularly advantageous if the
Schließlich ist es zweckmäßig, die beiden Andruckwalzen 14, 16 identisch auszubilden.Finally, it is expedient to design the two
