Abstract

The crossing thread supply system has four bobbin pairs which are disposed on rotatable disk-shaped elements. Each bobbin pair is guided downwardly through a tube which rotates with a respective rotatable element in non-rotatable relative relation. The tube extends obliquely so that all of the tubes deliver the respective thread pairs to twisting disks located in a relatively narrow lane.

Description

Die Erfindung betrifft eine Dreherfaden-Liefereinrichtung für eine Webmaschine mit wenigstens einem auf jeweils einem auf einem ortsfesten Lager rotierenden, scheibenförmigen Element angeordneten Fadenvorrats-Spulenpaar mit je einem nachgeschalteten, mit dem scheibenförmigen Element mitrotierenden Fadenableitorgan für die von dem zugehörigen Spulenpaar abgezogenen, zu einer Zwirneinrichtung und dann in das Webfach der Webmaschine geleiteten Dreherfäden.The invention relates to a leno thread delivery device for a weaving machine with at least one pair of thread bobbins arranged on a respective disc-shaped element rotating on a fixed bearing, each with a downstream thread-removing element for the thread-pulling element, which rotates with the disc-shaped element, to form a twisting device and then leno threads passed into the loom of the loom.

Bei einer bisherigen Einrichtung dieser Art (CH-PS 575 027) ist ein einziges Fadenvorrats-Spulenpaar auf einer rotierenden Scheibe angeordnet, an der ein nach unten gerichteter Verteilerdorn für das Ableiten der beiden Dreherfäden befestigt ist. Die feste Verbindung von Verteilerdorn und Spulentragscheibe ist so angeordnet, daß sich der Verteilerdorn senkrecht zu der Scheibe nach unten erstreckt.In a previous device of this type (CH-PS 575 027), a single pair of thread bobbins is arranged on a rotating disc, to which a downward-pointing distributor mandrel is attached for the derivation of the two leno threads. The fixed connection of the distributor mandrel and the coil support disk is arranged such that the distributor mandrel extends downwards perpendicularly to the disk.

Sollen mehrere solche Drehervorrichtungen für das Einleiten von mehreren Dreherfadenpaaren nebeneinander in eine Webmaschine verwendet werden, so entstehen verschiedene Schwierigkeiten. Werden z. B. vier der genannten Drehereinrichtungen mit parallel zueinander verlaufenden Verteilerdornen nebeneinander angeordnet, so liegen die unteren Enden der Verteilerdorne entsprechend weit voneinander entfernt, so daß die aus den Verteilerdornen abgeleiteten Dreherfadenpaare in ungünstigem Winkel auf die zugehörigen Zwirnscheiben geführt werden. Es entsteht dadurch an diesen ein ungünstiger Fadeneinlaufwinkel und eine erhöhte Reibung zwischen den Fäden und den Zwirnscheiben.Various difficulties arise when several such leno devices are used for introducing several pairs of leno threads side by side into a weaving machine. Are z. B. four of the above-mentioned leno devices with mutually parallel distributor mandrels are arranged next to one another, the lower ends of the distributor mandrels are correspondingly far apart, so that the leno thread pairs derived from the distributor mandrels are guided at an unfavorable angle onto the associated thread disks. This results in an unfavorable thread entry angle and increased friction between the threads and the thread disks.

Falls - zur Verminderung dieses Nachteils - die Zwirnscheiben in gewissem Abstand voneinander angeordnet werden, entsteht eine relativ breite, kettfadenfreie Gasse in der Webkette, was wiederum nachteilig ist.If - to reduce this disadvantage - the threading pulleys are arranged at a certain distance from one another, a relatively wide, warp-free lane is created in the warp, which in turn is disadvantageous.

Werden demgegenüber beispielsweise mehrere der genannten, bekannten Drehereinrichtungen schräg zueinander angeordnet, so befinden sich zwar die unteren Enden der Verteilerdorne näher beieinander, jedoch wird dann der gemeinsame Antrieb der Drehervorrichtungen umso schwieriger und komplizierter.In contrast, if, for example, several of the known turning devices are arranged obliquely to one another, the lower ends of the distributor mandrels are closer to each other, but then the common drive of the turning devices becomes all the more difficult and complicated.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Hinsicht verbesserte Dreherfaden-Liefereinrichtung zu schaffen, die sich dazu eignet, bei mehreren Dreherfadenpaaren und eng benachbarten Zwirnscheiben einen günstigen Fadeneinlauf zu ermöglichen.The invention has for its object to provide a leno thread delivery device which is particularly improved in this regard and is suitable for enabling a cheap thread inlet with several pairs of leno threads and closely adjacent threading disks.

Die Erfindung besteht darin, daß das als Rohr ausgebildete Fadenableitorgan an dem scheibenförmigen Element unter Zwischenschaltung eines drehsicheren Gelenkes angebracht ist und bezüglich der Rotationsachse des scheibenförmigen Elementes um eine schräg verlaufende Achse rotiert, wobei das ortsfeste Lager eine Schrägbohrung aufweist, durch die das rohrförmige Fadenableitorgan geführt ist.The invention consists in that the thread-guiding element designed as a tube is attached to the disc-shaped element with the interposition of a rotationally secure joint and rotates with respect to the axis of rotation of the disc-shaped element about an oblique axis, the stationary bearing having an oblique bore through which the tubular thread-guiding element is guided is.

Dadurch wird es möglich, die freien Enden der Fadenableitorgane (im folgenden sind Fadenableitrohre als Beispiel angenommen) in diejenige Ebene zu positionieren, in der auch die zugehörigen Zwirnscheiben nahe beieinander angeordnet sind. Die Führung der die Dreherfadenliefereinrichtung verlassenden Dreherfäden wird dadurch besonders zuverlässig, Reibung wird weitgehend vermieden.This makes it possible to position the free ends of the thread guiding elements (thread guiding tubes are taken as an example below) in the plane in which the associated threading disks are also arranged close to one another. The guidance of the leno threads leaving the leno thread delivery device is thereby particularly reliable, and friction is largely avoided.

Überdies können die zugehörigen Zwirnscheiben praktisch ohne Abstand nebeneinander positioniert werden, so daß nur eine relativ schmale, kettfadenfreie Gasse in der Webkette zur Anordnung der Zwirnscheiben benötigt wird.In addition, the associated threading pulleys can be positioned next to one another with practically no spacing, so that only a relatively narrow, warp-free alley in the warp is required to arrange the threading pulleys.

Auf einem Lagerteil 1 der nicht dargestellten Webmaschine ist eine Stütze 2 für eine als Ganzes mit 3 bezeichnete Dreherfaden-Liefereinrichtung befestigt. Die Einrichtung 3 enthält eine ortsfeste Grundplatte 4, auf welcher vier Scheiben 5 bis 8 unter Zwischenlage von vier ortsfesten Lagerteilen 13 drehbar gelagert sind. Jede Scheibe 5 bis 8 trägt ein Paar Vorratsspulen 11, 12. Jeder Lagerteil 13 enthält eine Schrägbohrung 14 für ein Fadenableitrohr 15.On a bearing part 1 of the weaving machine, not shown, a support 2 is attached for a leno thread delivery device designated as a whole by 3. The device 3 contains a stationary base plate 4 on which four disks 5 to 8 are rotatably supported with the interposition of four stationary bearing parts 13. Each disc 5 to 8 carries a pair of supply spools 11, 12. Each bearing part 13 contains an oblique bore 14 for a thread discharge pipe 15.

An dem in Fig. oberen Ende 70 des Fadenableitrohres 15 ist ein als Ganzes mit 16 bezeichnetes Kardangelenk angeordnet, über welches das Ableitrohr 15 an der zugehörigen Spulentragscheibe 8 aufgehängt ist. Das Kardangelenk 16 enthält zwei an der Scheibe 8 gebildete Lager 21, 22, in denen zwei Zapfen 23, 24 eines Kardanrahmens 25 mit Spiel geführt sind. In dem Rahmen 25 sind zwei Zapfen 26, 27 ebenfalls unter Spiel gelagert, welche an dem Fadenableitrohr 15 befestigt sind.At the upper end 70 of the thread discharge pipe 15 in FIG. 1 there is a cardan joint, designated as a whole by 16, via which the discharge pipe 15 is suspended from the associated bobbin support disk 8. The universal joint 16 contains two bearings 21, 22 formed on the disk 8, in which two pins 23, 24 of a gimbal 25 are guided with play. In the frame 25 two pins 26, 27 are also mounted with play, which are attached to the thread drain pipe 15.

Während des Betriebes wird die im Lager 1 befindliche Antriebswelle 31 für die Dreherfaden-Liefereinrichtung 3 synchron zur Hauptwelle der Webmaschine in Drehung versetzt. Über eine Welle 32 in der Stütze 2 wird ein Ritzel 33 angetrieben, welches die mit den Spulentragscheiben 7, 8 verbundenen Zahnkränze 34 antreibt. Außerdem steht das Ritzel 33 mit einem Ritzel 35 in Eingriff. Von ihm aus sind über entsprechende Zahnkränze 34 die beiden Spulentragscheiben 5, angetrieben.During operation, the drive shaft 31 in the bearing 1 for the leno thread delivery device 3 is rotated synchronously with the main shaft of the weaving machine. Via a shaft 32 in the support 2, a pinion 33 is driven, which drives the toothed rings 34 connected to the coil support disks 7, 8. In addition, the pinion 33 is in engagement with a pinion 35. From it, the two coil support disks 5 are driven via corresponding toothed rings 34.

Von jedem Spulenpaar 11, 12 werden nunmehr die beiden zugehörigen Dreherkettfäden 36, 37 abgezogen. Sie gelangen in die obere Öffnung 70 des zugehörigen Fadenableitrohres und in diesem in Fig. 3 abwärts zu den unteren Austrittsösen 38,39 des Rohres 15. Anschließend sind die Fäden 36, 37 durch Ösen 41, 42 einer ebenfalls von der Welle 31 aus angetriebenen Zwirnscheibe 43 und darauf in das Webfach (Kettfäden 71) der Webmaschine geführt.The two associated leno warp threads 36, 37 are now made from each pair of bobbins 11, 12 deducted. You get into the upper opening 70 of the associated thread discharge tube and in this downward in FIG. 3 to the lower outlet eyelets 38, 39 of the tube 15. The threads 36, 37 are then through eyelets 41, 42 of a threading disk likewise driven from the shaft 31 43 and then into the shed (warp threads 71) of the weaving machine.

Dadurch, daß die Fadenableitrohre 15 bei 16 kardanisch aufgehängt sind, wird es möglich, daß sie trotz ihrer Eigenrotation und der Rotation der zugehörigen Spulentragscheiben 5 bis 8 gemäß Pfeilen 51 immer die gleiche, schräge Position nach Fig. 3 bzw. 2 innehalten. Dadurch ist das untere Ende 52 jedes Ableitrohres 15 in der kettparallel verlaufenden Ebene E positioniert, die eine relativ schmale kettfadenfreie Gasse bildet und in welcher sich auch die zugehörigen Zwirnscheiben 43 befinden. Fadenreibung wird dadurch weitgehend ausgeschaltet; die Dreherfäden können über die zugehörigen Zwirnscheiben 43 in das Webfach der Webmaschine geleitet werden.The fact that the thread discharge pipes 15 are gimbaled at 16 makes it possible for them to always hold the same oblique position according to FIGS. 3 and 2 despite their own rotation and the rotation of the associated bobbin support disks 5 to 8 according to arrows 51. As a result, the lower end 52 of each discharge pipe 15 is positioned in the warp-parallel plane E, which forms a relatively narrow alley free of warp threads and in which the associated threading disks 43 are also located. Thread friction is largely eliminated; the leno threads can be passed into the weaving shed of the weaving machine via the associated threading disks 43.

Bei einem abgewandelten Ausführungsbeispiel sind nur zwei Spulenpaare 11, 12 auf zugehörigen Trägerscheiben 5, 8 vorhanden. Auch in diesem Fall können die zugehörigen Fadenableitrohre 15 infolge der Aufhängung mittels Kardangelenk 16 und der Schrägstellung mittels des Lagerteiles 13 mit ihren unteren Enden 52 während des Betriebes immer in der Ebene E der zugehörigen Zwirnscheiben 43 gehalten werden.In a modified embodiment, only two pairs of coils 11, 12 are present on associated carrier disks 5, 8. In this case too, the associated thread discharge pipes 15 can always be held in plane E of the associated threading disks 43 during operation due to the suspension by means of a universal joint 16 and the inclined position by means of the bearing part 13 with their lower ends 52 during operation.

Bei der Bauart nach Fig. 5 ist ein Kugelgelenk 60 zur Aufhängung des Fadenableitrohres 15 verwendet. Das Fadenableitrohr 15 enthält eine kugelförmige Partie 61, mit der es in der Spulentragscheibe 8 gelagert ist. Die kugelförmige Partie 61 besitzt eine in Fig. 5 von oben nach unten verlaufende, auf dem Kugelumfang verteilte Verzahnung 62, welche in eine entsprechende Gegenverzahnung 63 der Scheibe 8 sowie der Deckplatte 64 greift. Auch durch eine solche Art der Aufhängung des Rohres 15 läßt sich eine drehsichere Kupplung der Teile 15, 8 erzielen, wodurch es möglich wird, daß das Rohr 15 während der Drehung der Teile 8, 15 ständig die in Fig. gezeichnete, durch das Lager 13 verursachte Schrägstellung beibehält. Die Teile 4, 13 sind bei diesem Beispiel aus einem Stück hergestellt.5, a ball joint 60 is used to suspend the thread drain pipe 15. The thread discharge pipe 15 contains a spherical section 61 with which it is mounted in the bobbin support disk 8. The spherical part 61 has a toothing 62 which runs from top to bottom in FIG. 5 and is distributed over the circumference of the ball and which engages in a corresponding counter toothing 63 of the disk 8 and the cover plate 64. Even with such a type of suspension of the tube 15, a rotationally secure coupling of the parts 15, 8 can be achieved, which makes it possible for the tube 15 to rotate continuously during the rotation of the parts 8, 15 as shown in FIG maintains the inclination caused. The parts 4, 13 are made in one piece in this example.

Die Teile 8,64 bilden eine aus zwei Teilen 73, 74 bestehende Lagerschale für die kugelförmige Partie 61.The parts 8, 64 form a bearing shell for the spherical section 61 consisting of two parts 73, 74.

Bei den Teilen 16, 60 handelt es sich um drehsichere Gelenke. Es ist darunter zu verstehen, daß das Fadenableitrohr 15 relativ zu der zugehörigen Spulentragscheibe 8 verschwenkt werden kann; die Teile 15, 8 sind dabei aber auf Drehung miteinander gekuppelt (drehsicher), so daß die Rotation gemäß Pfeilen 51 gemeinsam erfolgt.The parts 16, 60 are non-rotatable joints. It is to be understood that the thread discharge tube 15 can be pivoted relative to the associated bobbin support disk 8; the parts 15, 8 are coupled to each other for rotation (non-rotatable), so that the rotation according to arrows 51 takes place together.
