Description

Die Erfindung bezieht sich auf eine Abzugsvorrichtung für die Stoffbahn an einer Textil-, vorzugsweise Webmaschine, mit einer angetriebenen Stoffabzugswalze und je einem ihr vor- bzw. nachgeschalteten, stangenförmigen Umlenkelement für den Stoff, wobei die Umlenkelemente unter Zwischenlage des Stoffes an der Stoffabzugswalze anliegen und - mindestens beim Betrieb - ortsfest angeordnet sind. Eine solche Vorrichtung ist im wesentlichen aus der DD-PS 78 973 bekannt. Die Abzugsvorrichtung ist insbesondere bestimmt für Webmaschinen mit ausserordentlich hoher Stoffabzugsspannung und hoher Leistung, d.h. grosser Webbreite und hoher Drehzahl.The invention relates to a take-off device for the fabric web on a textile, preferably weaving machine, with a driven fabric take-off roller and a rod-shaped deflecting element for the fabric upstream or downstream thereof, the deflecting elements abutting the fabric take-up roller with the interposition of the fabric and - at least during operation - are arranged in a fixed position. Such a device is essentially known from DD-PS 78 973. The take-off device is particularly intended for weaving machines with extremely high fabric take-off tension and high performance, i.e. large weaving width and high speed.

Bei einer bisherigen Vorrichtung dieser Art (CH-PS 615 644 = DE-OS 2 803 845) besitzt das der Stoffabzugswalze vorgeschaltete, als Walze ausgebildete Umlenkelement glatte Oberfläche und wird von dem darüberlaufenden und auf die Stoffabzugswalze gelangenden Stoff mitgenommen bzw. in Drehung versetzt. Dabei ist in der Praxis folgende Erscheinung zu beobachten.In a previous device of this type (CH-PS 615 644 = DE-OS 2 803 845), the upstream of the fabric take-off roller, designed as a roller deflection element, has a smooth surface and is carried along by the material running over it and onto the fabric take-off roller or set in rotation. The following phenomenon can be observed in practice.

Unter der starken Abzugsspannung seitens der Abzugsvorrichtung kann das Gewebe im Bereich zwischen Blattanschlag bzw. Breithalter einerseits und der Stoffabzugswalze anderseits einen starken Einsprung erfahren. Dies kommt daher, dass der Stoff nach Verlassen der Breithalter zunächst frei läuft und durch die Schussfadenspannung in Schussrichtung relativ stark zusammengezogen wird. Die Kettfadenspannung ist jedoch stärker als die Schussfadenspannung. Das Gewebe strebt einen Zustand an, bei dem der Umschlingungswinkel der Schussfäden um die Kettfäden herum grösser ist als derjenige der Kettfäden um die Schussfäden herum.Under the strong take-off tension on the part of the take-off device, the fabric in the area between the sheet stop or spreader on the one hand and the fabric take-off roller on the other hand can experience a strong jump. This is due to the fact that the fabric initially runs freely after leaving the spreader and is pulled together relatively strongly by the weft thread tension in the weft direction. However, the warp thread tension is stronger than the weft thread tension. The fabric is striving for a state in which the wrap angle of the weft threads around the warp threads is greater than that of the warp threads around the weft threads.

Die Gewebebahn läuft nun in diesem einseitig verspannten Zustand in die Abzugsvorrichtung - ein, welche mit besonders hohen Anpressdrücken auf dem Umfang der Stoffabzugswalze arbeitet. Es soll dabei ermöglicht werden, dass die Abzugswalzen keine besonders rauhe Oberfläche, z.B. Korund, und auch keine Mitnehmernadeln besitzen muss, weil diese Einrichtungen auf empfindliche Gewebe schädlich einwirken.In this one-sided tensioned state, the fabric web now runs into the take-off device, which works with particularly high contact pressures on the circumference of the fabric take-off roller. It should be made possible that the take-off rollers do not have a particularly rough surface, e.g. Corundum, and also need not have driver pins, because these devices have a harmful effect on sensitive tissues.

Es ist nun weiterhin festzustellen, dass anderseits der abgezogene Stoff bleibende Falten beim Ablauf von der Warenabzugswalze erhalten kann. Hier setzt nun die Erfindung ein, deren Ziel es ist, Massnahmen zu treffen, wodurch diese unerwünschten Falten im Stoff vermieden werden können.It can now also be determined that, on the other hand, the removed fabric can receive permanent creases when it runs off the take-off roller. This is where the invention comes in, the aim of which is to take measures which can prevent these undesirable creases in the fabric.

Als Grund für die Ablauffalten wurde erkannt, dass beim Ablaufen von der Stoffabzugswalze auf das Gewebe seitens des Warenbaumes die in der Regel wesentlich geringere Warenbaum-Abzugsspannung ausgeübt wird. Gegebenenfalls kann das Gewebe sogar völlig spannungslos in einen Behälter abgelegt werden. Infolgedessen kann das Gewebe in diesem Abzugsbereich der Warenabzugswalze unter der noch bestehenden Schussfadenspannung wieder verbreitert werden, so dass die genannten Falten entstehen können, die unter der zwischen Stoffabzugswalze und nachgeschalteter Umlenkrolle bestehenden Klemmstelle bleibend in den Stoff eingedrückt werden können.It was recognized as the reason for the drain folds that when the fabric take-off roller runs down onto the fabric on the part of the fabric, the generally lower fabric take-off tension is exerted. If necessary, the tissue can even be placed in a container without tension. As a result, the fabric in this take-off area of the take-off roller can be widened again under the still existing weft thread tension, so that the creases mentioned can arise which can be permanently pressed into the fabric under the nip between the take-off roller and the downstream deflection roller.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Hinsicht verbesserte Abzugsvorrichtung zu schaffen, insbesondere hohe Rutschfestigkeit auf der Abzugswalze und Vermeidung von Falten im Abzug des Gewebes zu erreichen.The invention has for its object to provide a haul-off device which is particularly improved in this regard, in particular to achieve high slip resistance on the haul-off roller and avoid wrinkles in the haul-off of the fabric.

Die Erfindung besteht darin, dass die Stoffabzugswalze quer zu ihrer Achsrichtung beweglich angeordnet und der lichte Abstand der Umlenkelemente kleiner ist als der Durchmesser der Stoffabzugswalze und dass das der Stoffabzugswalze vorgeschaltete Umlenkelement als gegen Drehung gesicherte Stange ausgebildet ist, die in ihren beiden Hälften gegenläufige - in Laufrichtung der Stoffbahn gesehen -, auseinanderlaufende Gewinderillen aufweist.The invention consists in that the material take-off roller is arranged to be movable transversely to its axial direction and the clear distance between the deflecting elements is smaller than the diameter of the material take-off roller and that the deflecting element upstream of the material take-off roller is designed as a rod secured against rotation, the two halves of which are opposed - in Seen the direction of the fabric - has diverging thread grooves.

Hierdurch wird es möglich, hohe Rutschfestigkeit bei relativ geringer Rauhigkeit der Oberfläche der Abzugswalze zu erreichen. Dabei wird der Stoff unmittelbar vor dem Auflaufen bzw. beim Auflaufen auf die Stoffabzugswalze in die Breite gestreckt, so dass er in dieser gestreckten Form auf die Walze gelangt. Durch den starken, sich ändernden, auf dem Umfang der Stoffabzugswalze herrschenden Anpressdruck aufgrund der besonderen Ausbildung der Stoffabzugsvorrichtung, d.h. der schwimmend gelagerten Abzugswalze und des Abstandes der Umlenkelemente, gegen welche die Abzugswalze um so stärker gepresst wird, je grösser der Stoffzug ist, bleibt die breitgestreckte Form auf dem Umfang weitgehend erhalten.This makes it possible to achieve high slip resistance with a relatively low roughness of the surface of the take-off roller. The fabric is stretched in width immediately before it comes up or when it comes up onto the fabric take-off roller, so that it reaches the roller in this stretched form. Due to the strong, changing contact pressure on the circumference of the fabric take-off roller due to the special design of the fabric take-off device, i.e. The floating take-off roller and the distance of the deflection elements against which the take-off roller is pressed the stronger the larger the fabric, the broad shape is largely preserved on the circumference.

Beim Verlassen der Stoffabzugswalze bzw. bereits kurz davor gelangt jedoch der Stoff unter die geringere Kettspannung auf der Ablaufseite. Da er aber hier wegen der drehsicheren, gerillten Auflaufstange bereits volle Breite besitzt, kann eine weitere Verbreiterung beim Nachlassen der Kettspannung vermieden werden. Demzufolge können, wie die Versuche ergeben, die unerwünschten Falten vermieden werden, die bisher beim Ablauf von der Abzugsvorrichtung, insbesondere unter dem Druck des nachgeschalteten Umlenkelementes auftreten können.When leaving the fabric take-off roller or shortly before, however, the fabric comes under the lower warp tension on the discharge side. However, since it already has full width due to the non-rotatable, grooved overrun rod, a further widening when the warp tension is released can be avoided. As a result, as the experiments show, the undesirable folds which up to now could have occurred during the discharge from the extraction device, in particular under the pressure of the downstream deflection element, can be avoided.

Der Stoff 1 (Webbreite B) wird gemäss Pfeil 51 über eine Gewebestütze 52 einer Umlenkstange 3 zugeführt. Diese enthält in ihren Abschnitten (38, 39) gegenläufige - in Laufrichtung 51 der Stoffbahn 1 -, auseinanderlaufende Gewinderillen 41, 42 (vgl. Fig. 3). Darauf gelangt der Stoff 1 über eine mit einer Gummiauflage 4 versehene Abzugswalze 5 und anschliessend über eine ihr nachgeschaltete Umlenkrolle 3c zu einem Warenbaum 65, auf dem der Stoff 1 aufgewickelt wird. Walze 5 hat einen Durchmesser D, der grösser ist als der lichte Abstand A der Teile 3, 3c.The fabric 1 (weaving width B) is fed according to arrow 51 via a fabric support 52 to a deflecting rod 3. In its sections (38, 39) opposite thread grooves 41, 42 (see FIG. 3) that diverge in the direction of travel 51 of the fabric web 1. The fabric 1 then passes through a take-off roller 5 provided with a rubber pad 4 and then via a deflecting roller 3c arranged downstream thereof to a fabric tree 65 on which the fabric 1 is wound. Roller 5 has a diameter D which is greater than the clear distance A between the parts 3, 3c.

Die Warenabzugswalze 5 wird, wie aus Fig. 2 ersichtlich, über Zahnräder 18, 19, 20 angetrieben, die in der einen Wange 23 des Maschinengestelles 2 gelagert sind. Vom Zahnrad 20 wird der Antrieb über ein Kardan- oder Kugelgelenk 21 auf die Walze 5 geleitet. Walze 5 ist also während des Betriebes in konstante Drehung versetzt (positiver Warenabzug).As can be seen from FIG. 2, the goods take-off roller 5 is driven via gear wheels 18, 19, 20, which are mounted in one cheek 23 of the machine frame 2. The drive is guided from the gear wheel 20 to the roller 5 via a cardan or ball joint 21. Roller 5 is thus set in constant rotation during operation (positive goods deduction).

Während die beiden Umlenkelemente (3, 3c) - in der in Fig. 1 dargestellten Betriebsstellung der Teile (bei Umlenkstange 3 = ausgezogen wiedergegebene Stellung nach Fig. 1) - ortsfest angeordnet sind und Umlenkrolle 3c vom Stoff 1 mitgenommen, also in Drehung versetzt wird (Pfeil 58), ist die Abzugswalze 5 infolge des Gelenkes 21 quer zu ihrer Achslinie 62 beweglich (vgl. Pfeil 25 in Fig. 1).While the two deflecting elements (3, 3c) - in the operating position of the parts shown in FIG. 1 (with deflecting rod 3 = solid position shown in FIG. 1) - are arranged in a fixed manner and deflecting roller 3c is carried along by the fabric 1, that is to say is set in rotation (Arrow 58), the take-off roller 5 is movable transversely to its axis line 62 as a result of the joint 21 (cf. arrow 25 in FIG. 1).

Die gesamte Stoffabzugsvorrichtung ist in Fig. 1 mit 15 bezeichnet. Die der Hauptabzugswalze 5 vorgeschaltete Stange 3 besitzt eine Nut 53, in welche ein Träger 47 eingreift, der mit einer Stange 55 verbunden ist. Diese ist in einer Mulde 56 eines Halters 6 des Maschinengestells 2 drehbar gelagert. Auf diese Weise lässt sich die Umlenkstange 3 gemäss Pfeil 46 in die strichpunktiert eingezeichnete Position 3b verschwenken, wenn der Stoff 1 spannungslos oder abgenommen ist.The entire fabric removal device is designated by 15 in FIG. 1. The rod 3 upstream of the main take-off roller 5 has a groove 53 into which a carrier 47 engages, which is connected to a rod 55. This is rotatably mounted in a trough 56 of a holder 6 of the machine frame 2. In this way, the deflecting rod 3 can be pivoted according to arrow 46 into the position 3b shown in dash-dot lines when the fabric 1 is tensionless or removed.

Während des Betriebes wird der Träger 47 ständig gegen einen Anschlag 48 des Halters 6 gedrückt. Dies wird dadurch erzielt, dass der Drehpunkt 57 der Stange 55 so gewählt ist, dass die während des Betriebes seitens des Stoffes 1 sich ergebende, aus dem Stoffzug Z und der Zug-Kraftkomponente P resultierende Kraft R in Fig. 1 unterhalb des Drehpunktes 57 verläuft. Hierdurch entsteht während des Betriebs ein im Gegenzeigersinn gerichtetes Drehmoment um den Drehpunkt 57.During operation, the carrier 47 is constantly pressed against a stop 48 of the holder 6. This is achieved in that the fulcrum 57 of the rod 55 is selected such that the force R resulting from the fabric 1 and the tensile force component P resulting from the fabric 1 during operation runs below the fulcrum 57 in FIG. 1 . This creates a counterclockwise torque about pivot 57 during operation.

Die der Abzugswalze 5 nachgeschaltete Rolle 3c ist in einer Mulde 22 des Gestells 6 drehbar gelagert.The roller 3c connected downstream of the take-off roller 5 is rotatably mounted in a trough 22 of the frame 6.

Durch die Gewinderillen 41, 42 kann der über Stange 3 rutschende Stoff 1 unmittelbar vor dem Auflaufen auf die Abzugswalze 5 breitgestreckt werden. Er kann dann nicht unter der starken Abzugsspannung P seitens der Walze 5 schmaler werden (Stoffeinsprung),Through the thread grooves 41, 42, the material 1 sliding over the rod 3 can be stretched immediately before it runs onto the take-off roller 5. It cannot then become narrower under the strong take-off tension P on the part of the roller 5 (material injection),

Dies wiederum hat zur Folge, dass der Stoff etwa im Bereich 71, wo er Walze 5 verlässt und auf Rolle 3c gelangt und wo die wesentlich niedrigere Zugspannung S seitens des Warenbaumes 65 herrscht, nicht breiter werden kann. Hierdurch lassen sich - wie die Versuche ergaben - Falten im fertigen Stoff 1 vermeiden.This in turn has the consequence that the fabric cannot widen, for example in the area 71 where it leaves roller 5 and reaches roll 3c and where the substantially lower tensile stress S prevails on the part of the fabric tree 65. As a result, as the tests showed, folds in the finished fabric 1 can be avoided.

Es ist zu erwähnen, dass ohne Breitstreckung des Stoffes 1 unmittelbar beim Übergang von Stange 3 auf Walze 5 ein mehr oder weniger starker Einsprung in Schussrichtung entstehen kann; dieser kann ein Auseinanderstossen im Bereich 71 zur Folge haben, wodurch Falten im fertigen Stoff 1 entstehen können, die besonders an der Anpressstelle 72 in den Stoff bleibend eingedrückt werden können.It should be mentioned that without spreading the fabric 1, a more or less strong jump in the weft direction can occur directly at the transition from rod 3 to roller 5; This can result in a knocking apart in the area 71, as a result of which folds can arise in the finished fabric 1, which can be permanently pressed into the fabric, particularly at the pressing point 72.

Bei der Ausführungsform nach Fig. ist die Umlenkstange 3 wie in Fig. 1 ausgebildet, d. h. gegen Drehung gesichert. An den Enden trägt sie schräggestellte Nadelrollen 61a, die - unter Innehaltung ihrer Schrägstellung im Raum - drehbar gelagert sind. Die wirksame Länge der Umlenkstange 3 ist der Breite B des Stoffes 1 angepasst. Die Rollen 61a verursachen zusammen mit den Gewinderillen 41, 42 eine Breitstreckung des Stoffes 1.In the embodiment according to FIG. 3, the deflecting rod 3 is designed as in FIG. H. secured against rotation. At the ends it carries inclined needle rollers 61a, which - while keeping their inclined position in space - are rotatably mounted. The effective length of the deflection rod 3 is adapted to the width B of the fabric 1. The rollers 61a together with the thread grooves 41, 42 cause the fabric 1 to spread.

Die Teile 3, 3c sind mindestens während des Betriebes ortsfest gelagert. Walze 5 wird unter dem Stoffzug Z gegen die Teile 3, 3c gepresst, wodurch ein Zurückrutschen des Stoffes 1 vermieden werden kann. Die nachgeschaltete Umlenkrolle 3c kann auch durch einen separaten Antrieb angetrieben sein, vgl. Pfeil 58. Ihre Umfangsgeschwindigkeit kann höher sein als diejenige der Abzugswalze 5.The parts 3, 3c are stored in a stationary manner at least during operation. Roller 5 is pressed under the fabric pull Z against the parts 3, 3c, whereby slipping back of the fabric 1 can be avoided. The downstream deflection roller 3c can also be driven by a separate drive, cf. Arrow 58. Their peripheral speed can be higher than that of the take-off roller 5.
