Abstract

A thread splicing assembly (10) has a splice channel with a compressed air inlet. The assembly has esp. two rotating prisms (27, 28) which each turn from a thread pick-up presentation to a splice presentation. Together the two prisms form a splice passage (44). <??>One or both of the prisms has a compressed air inlet (42). The prisms are pref. identical. Each prism has an air distribution passage from which two compressed air inlets branch off and enter the splice passage at a tangent. Each prism has a detachable cover (30) with a convex seal interface seal and an air connector. The prisms are driven by a step motor (27, 28) linked to a computer.

Description

Die Erfindung betrifft eine Fadenspleißvorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a yarn splicing apparatus according to the Preamble of claim 1.

Fadenspleißvorrichtungen zum pneumatischen Verbinden zweier Fadenenden sind im Zusammenhang mit Kreuzspulautomaten seit langem bekannt und in zahlreichen Schutzrechtsanmeldungen beschrieben, wie in der CH-A-439 168.Thread splicing devices for pneumatically connecting two Yarn ends have been associated with automatic winder since long known and in numerous patent applications described in CH-A-439 168.

Es sind dabei sowohl Fadenspleißvorrichtungen bekannt, bei denen der Fadeneinlegeschlitz eines in einem sogenannten Spleißkopf angeordneten Spleißkanals während des Spleißvorganges unverschlossen bleibt, als auch Fadenspleißvorrichtungen, bei denen dieser Fadeneinlegeschlitz während des Spleißvorganges durch ein spezielles Deckelelement verschlossen wird.There are both Fadensleiißvorrichtungen known, at the thread insertion slot one in a so-called Splice head arranged splice channel during the Splicing process remains unlocked, as well Thread splicing devices in which this thread insertion slot during the splicing process by a special cover element is closed.

Die DE 39 35 536 C2 beschreibt beispielsweise eine Fadenspleißvorrichtung, mit einem Spleißkopf, dessen Spleißkanal einen etwa kreisförmigen Querschnitt aufweist.
In den Spleißkanal münden tangential Druckluft-Einblasöffnungen. Der Spleißkanal verfügt auf seiner Oberseite außerdem über einen durchgehenden Schlitz, über den die zu verspleißenden Fadenenden eingefädelt werden können. Dieser Fadeneinlegeschlitz kann während des Spleißprozesses durch ein Deckelelement verschlossen werden.
DE 39 35 536 C2 describes, for example, a yarn splicing device, with a splice head, the splice has an approximately circular cross-section.
In the splice channel open tangential compressed air injection openings. The splice channel also has on its upper side a continuous slot through which the thread ends to be spliced can be threaded. This Fadeneinlegeschlitz can be closed during the splicing process by a cover element.

Derartige Fadenspleißvorrichtungen mit oder ohne Deckelelement haben sich in der Praxis im Prinzip bewährt.
Bei deckellosen Spleißvorrichtungen ergeben sich allerdings gelegentlich Schwierigkeiten beim Einlegen der Fadenenden in den Spleißkanal, da bei diesen Fadenspleißvorrichtungen der Fadeneinlegeschlitz meistens relativ schmal ausgebildet ist.
Such yarn splicing devices with or without cover element have proven themselves in practice in principle.
In coverless splicing, however, sometimes difficulties arise when inserting the thread ends in the splice, since in these Fadenspleißvorrichtungen the Fadeneinlegeschlitz is usually made relatively narrow.

Fadenspleißvorrichtungen, deren Spleißkanal durch ein schwenkbar gelagertes Deckelelement verschließbar ist, weisen den Nachteil auf, daß solche Einrichtungen oft relativ sperrig sind, das heißt, solche Fadenspleißvorrichtungen benötigen einen relativ großen Einbauraum.Thread splicing devices whose splice channel by a pivotally mounted lid member is closed, show the disadvantage that such facilities often relatively bulky are, that is, need such thread splicing devices a relatively large installation space.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, eine Fadenspleißvorrichtung zu schaffen, die die vorgenannten Nachteile nicht aufweist.Based on the aforementioned prior art is the Invention therefore an object of the invention To provide yarn splicing device, the aforementioned Disadvantages not.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved by a device dissolved, as described in claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Dependent claims.

Die erfindungsgemäße Ausführungsform hat insbesondere den Vorteil, daß eine derartige Vorrichtung einerseits in ihrem konstruktiven Aufbau äußerst kompakt gestaltet ist, andererseits die zu verspleißenden Fadenenden problemlos im Bereich des Spleißkanals positionierbar sind.
Das heißt, durch den Einsatz zweier drehbar gelagerter Prismenteile ist es auf einfache Weise möglich, die durch eine Saugdüse beziehungsweise ein Greiferrohr vorgelegten Fadenenden sicher innerhalb des Spleißkanals zu positionieren und dort für den Spleißvorgang zu fixieren.
The embodiment according to the invention has the particular advantage that such a device is designed to be extremely compact, on the one hand, in terms of its structural design, and, on the other hand, that the thread ends to be spliced can be positioned without difficulty in the region of the splice channel.
That is, by the use of two rotatably mounted prism parts, it is possible in a simple manner, to securely position the thread ends presented by a suction nozzle or a gripper tube within the splice channel and to fix it there for the splicing process.

In vorteilhafter Ausbildung ist dabei, wie im Anspruch 2 dargelegt, vorgesehen, daß wenigstens eines der Primenteile eine Druckluft-Einblasöffnung aufweist.
Eine solche Druckluft-Einblasöffnung ermöglicht das gezielte Einblasen von Spleißluft in den durch die Primenteile gebildeten Spleißkanal, wobei das Prismenteil, das keine Druckluft-Einblasöffnung besitzt als Deckelelement wirkt.
In an advantageous embodiment, it is provided, as stated in claim 2, that at least one of the Primenteile having a compressed air injection opening.
Such a compressed-air injection opening enables the targeted injection of splicing air into the splicing channel formed by the pellets, the prism portion, which has no compressed-air injection opening, acting as a cover element.

Wie im Anspruch 3 dargelegt, ist in bevorzugter Ausbildung vorgesehen, daß in das Prismenteil jeweils ein Luftverteilungskanal eingearbeitet ist. Von diesem Luftverteilungskanal zweigen, vorzugsweise zwei Druckluft-Einblasöffnungen ab, die in den Spleißkanal münden.
Über den Luftverteilungskanal und die Druckluft-Einblasöffnungen kann Spleißluft in den Spleißkanal eingeblasen werden. Diese Spleißluft sorgt für eine gegenseitige Verwirbelung der im Spleißkanal positionierten, vorher weitestgehend von ihrer Spinndrehung befreiten Fadenenden.
Das heißt, mit der im Anspruch 3 beschriebenen Ausführungsform lassen sich sichere und haltbare Fadenverbindungen herstellen.
As set forth in claim 3, it is provided in a preferred embodiment that in the prism portion in each case an air distribution channel is incorporated. From this air distribution channel branch off, preferably two compressed air injection openings, which open into the splice channel.
Splicing air can be injected into the splice channel via the air distribution channel and the compressed air injection openings. This splicing air ensures mutual turbulence of the thread ends positioned in the splicing channel, previously largely freed from their spinning rotation.
That is, with the embodiment described in claim 3 can be made safe and durable thread connections.

In bevorzugter Ausführungsform münden die Druckluft-Einblasöffnungen dabei jeweils tangential in den Spleißkanal (Anspruch 4).
Die tangentiale Anordnung der Einblasöffnungen gewährleistet, daß innerhalb des Spleißkanals eine wenigstens teilweise rotierende Luftströmung entsteht.
In a preferred embodiment, the compressed air injection openings each open tangentially into the splice channel (claim 4).
The tangential arrangement of the injection openings ensures that an at least partially rotating air flow arises within the splicing channel.

Eine solche rotierende Luftströmung führt zu festen, nahezu garngleichen Fadenverbindungen.Such a rotating air flow leads to firm, almost yarn-like thread connections.

Gemäß Anspruch 5 sind die beiden Prismenteile identisch ausgebildet und weisen jeweils wenigstens eine Druckluft-Einblasöffnung auf.
Durch die Verwendung identischer Bauteile lassen sich einerseits die Herstellungskosten dieser Teile, insbesondere wenn diese Teile als Spritz- oder Druckgußteile hergestellt sind, relativ günstig gestalten, andererseits vereinfacht eine solche Ausbildung auch die Lagerhaltung erheblich.
According to claim 5, the two Prismenteile are identical and each have at least one compressed air injection opening.
By using identical components can on the one hand, the manufacturing cost of these parts, especially if these parts are made as injection or die cast parts, make relatively cheap, on the other hand simplifies such training and storage considerably.

Wie im Anspruch 6 dargelegt, bestehen die Prismenteile in bevorzugter Ausführungsform jeweils aus einem etwa zylindrischen Prismenkörper sowie einem lösbaren, rückwärtigen Deckelelement.
Die Prismenkörper sind dabei so ausgebildet, daß in der Fadenaufnahmestellung zwischen den Prismenkörpern ausreichend Platz zum Einlegen der zu verspleißenden Fadenenden vorhanden ist.
In der Spleißstellung liegen die Prismenkörper jeweils so am gegenüberliegenden Prismenkörper an, daß zwischen den Prismenkörpern ein weitestgehend geschlossener Spleißkanal gebildet ist.
As set forth in claim 6, the prism parts in a preferred embodiment each consist of an approximately cylindrical prism body and a detachable, rear cover element.
The prism body are designed so that in the thread receiving position between the prism bodies sufficient space for inserting the thread ends to be spliced is present.
In the splice position, the prism bodies abut each other on the opposite prism body such that a largely closed splice channel is formed between the prism bodies.

Gemäß Anspruch 7 ist in bevorzugter Ausgestaltung außerdem vorgesehen, daß die an den Prismenteilen festlegbaren rückwärtigen Deckelelemente jeweils eine konvex gerundete Dichtfläche aufweisen, in die eine Luftanschlußbohrung eingearbeitet ist.
Diese konvex gerundete Dichtfläche der Deckelelemente korrespondiert jeweils mit einer entsprechend konkav gewölbten Dichtfläche eines stationären, druckluftbeaufschlagbaren Anschlußmittels.
Das heißt, das Anschlußmittel ist über eine Pneumatikleitung, in die beispielsweise ein Elektromagnetventil eingeschaltet ist, mit einer Druckluftquelle verbunden, so daß durch entsprechende Ansteuerung des Elektromagnetventils gezielt Spleißluft in den Spleißkanal eingeblasen werden kann.
Über zum Beispiel die Öffnungsdauer des Elektromagnetventils kann dabei die Wirkung der Spleißluft individuell auf das jeweilige Material oder die Stärke der zu verspleißenden Fadenenden angepaßt werden.
According to claim 7 is also provided in a preferred embodiment that the fixable on the prism parts rear cover elements each have a convexly rounded sealing surface, in which an air connection bore is incorporated.
This convexly rounded sealing surface of the cover elements corresponds in each case to a correspondingly concavely curved sealing surface of a stationary, pressurizable connecting means.
That is, the connection means is connected via a pneumatic line, in which, for example, a solenoid valve is turned on, with a compressed air source, so that targeted by splitting the solenoid valve splicing air can be injected into the splice.
By way of example, the opening duration of the solenoid valve, the effect of the splicing air can be individually adapted to the particular material or the strength of the yarn ends to be spliced.

Wie in den Ansprüchen 8 und 9 weiter beschrieben, sind die Prismenteile in einem Grundkörper der Fadenspleißvorrichtung begrenzt schwenkbar gelagert.
Der Antrieb der Prismenteile erfolgt dabei vorteilhafterweise über einen durch den Arbeitsstellenrechner ansteuerbaren Antrieb, beispielsweise einen-Schrittmotor.
Solche Schrittmotoren stellen im Handel erhältliche, kostengünstige Großserienbauteile dar, die auf verschiedenen Einsatzgebieten erprobt sind und sich als langlebig und zuverlässig erwiesen haben.
As further described in claims 8 and 9, the Prismenteile are limited pivotally mounted in a main body of the yarn splicing device.
The drive of the Prismenteile takes place advantageously via a controllable by the workstation computer drive, such as a stepper motor.
Such stepper motors are commercially available, low cost, high volume components that have been tried and tested in a variety of applications and have proven durable and reliable.

Weitere Einzelheiten der Erfindung sind einem nachfolgend anhand der Zeichnungen erläuterten Ausführungsbeispiel entnehmbar.Further details of the invention are given below Embodiment explained with reference to the drawings removable.

In Figur 1 ist in Vorderansicht schematisch eine insgesamt mit der Bezugszahl 1 gekennzeichnete Kreuzspulen herstellende Textilmaschine, im Ausführungsbeispiel ein Kreuzspulautomat, dargestellt.
Derartige Kreuzspulautomaten weisen üblicherweise zwischen ihren (nicht dargestellten) Endgestellen eine Vielzahl gleichartiger Arbeitsstellen, im vorliegenden Fall Spulstellen 2, auf.

Such automatic packages usually have between their (not shown) Endgestellen a variety of similar jobs, in this case winding units 2, on.

Auf diesen Spulstellen 2 werden, wie bekannt und daher nicht näher erläutert, die auf einer Ringspinnmaschine produzierten Spinnkopse 9 zu großvolumigen Kreuzspulen 15 umgespult.
Nach ihrer Fertigstellung werden diese Kreuzspulen 15 mittels eines selbsttätig arbeitenden Serviceaggregates, vorzugsweise eines (nicht dargestellten) Kreuzspulenwechslers, auf eine maschinenlange Kreuzspulentransporteinrichtung 21 übergeben und zu einer maschinenendseitig angeordneten Spulenverladestation oder dergleichen transportiert.
On these winding units 2, as is known and therefore not explained in more detail, the spinning cops 9 produced on a ring spinning machine are rewound into large-volume cheeses 15.
After their completion, these cheeses 15 are transferred by means of an automatically operating service unit, preferably a (not shown) cheese change on a machine-length cheese package transport means 21 and transported to a machine end side Spulenverladestation or the like.

Solche Kreuzspulautomaten 1 weisen außerdem eine Logistikeinrichtung in Form eines Spulen- und Hülsentransportsystems 3 auf. In diesem Spulen- und Hülsentransportsystem 3 laufen, auf Transporttellern 8, die Spinnkopse 9 beziehungsweise Leerhülsen um.
Von dem Spulen- und Hülsentransportsystem 3 sind in Figur 1 lediglich die Kopszuführstrecke 4, die reversierend antreibbare Speicherstrecke 5, eine der zu den Spulstellen 2 führenden Quertransportstrecken 6 sowie die Hülsenrückführstrecke 7 dargestellt.
Such spooling machines 1 also have a logistics device in the form of a spool and sleeve transport system 3. In this bobbin and tube transport system 3 run on transport plates 8, the spinning cops 9 or empty tubes to.
Of the bobbin and tube transport system 3, only the Kopszuführstrecke 4, the reversibly driven storage section 5, one of the leading to the winding units 2 transverse transport sections 6 and the sleeve return path 7 are shown in Figure 1.

Wie vorstehend bereits angedeutet, werden die angelieferten Spinnkopse 9 in den Abspulstellungen AS, die sich jeweils im Bereich der Quertransportstrecken 6 an den Spulstellen 2 befinden, zu großvolumigen Kreuzspulen 15 umgespult.
Die einzelnen Spulstellen verfügen zu diesem Zweck, wie bekannt und daher nur angedeutet, über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb dieser Arbeitsstellen gewährleisten. Diese Einrichtungen sind beispielsweise eine Saugdüse 12, ein Greiferrohr 25 sowie eine Fadenspleißvorrichtung 10. Die Fadenspleißvorrichtung 10 ist dabei vorzugsweise als pneumatischer Spleißer ausgebildet.
As already indicated above, the delivered spinning cops 9 are rewound in the Abspulstellungen AS, which are each located in the region of the transverse transport lines 6 at the winding units 2, to large-volume cheeses 15.
The individual winding units have for this purpose, as known and therefore only hinted at various facilities that ensure proper operation of these jobs. These devices are, for example, a suction nozzle 12, a gripper tube 25 and a yarn splicing device 10. The yarn splicing device 10 is preferably designed as a pneumatic splicer.

Solche Spulstellen 2 verfügen außerdem über weitere, nicht näher dargestellte Einrichtungen, wie einen Fadenspanner, einen Fadenreiniger, eine Paraffiniereinrichtung, eine Fadenschneideinrichtung, einen Fadenzugkraftsensor sowie einen Unterfadensensor.Such winding units 2 also have more, not detailed devices, such as a thread tensioner, a thread cleaner, a waxing device, a Thread cutter, a yarn tension sensor and a Bobbin thread sensor.

Des weiteren verfügt ein solcher Kreuzspulautomat 1 üblicherweise über eine (nicht dargestellte) Zentralsteuereinheit, die über einen Maschinenbus sowohl mit den separaten Arbeitsstellenrechnern 29 der einzelnen Spulstellen 2 als auch mit einer Steuereinrichtung des Serviceaggregates verbunden ist.Furthermore, such a cross-winding machine has 1 usually via a (not shown) Central control unit via a machine bus with both the separate workstation computers 29 of the individual Spooling 2 as well as with a control device of the Service units is connected.

Das Wickeln der Kreuzspulen 15 erfolgt dabei auf sogenannten Spulvorrichtungen 24. Diese Spulvorrichtungen 24 verfügen unter anderem über einen Spulenrahmen 45, der um eine Schwenkachse 13 beweglich gelagert ist und eine Einrichtung zum drehbaren Haltern der Kreuzspulenhülse aufweist. Während des Spulprozesses liegt die im Spulenrahmen frei drehbar gelagerte Kreuzspule 15 mit ihrer Oberfläche auf einer angetriebenen Nuttrommel 14 und wird von dieser über Reibschluß mitgenommen.The winding of the cheeses 15 takes place on so-called Winding devices 24. These winding devices 24 have inter alia, via a coil frame 45, which is around a Pivot axis 13 is movably mounted and a device for rotatably supporting the cheese coil. While the winding process is freely rotatable in the coil frame mounted cheeses 15 with their surface on one driven grooved drum 14 and is about this Friction entrained.

Wie vorstehend bereits angedeutet, verfügt jede Arbeitsstelle 2 über eine Saugdüse 12 sowie ein Greiferrohr 25. Die Saugdüse 12, die den Oberfaden 31 von der Kreuzspule 15 zurückholt und in die Fadenspleißvorrichtung 10 einlegt, ist dabei um eine Drehachse 16 begrenzt schwenkbar. As already indicated above, each has Job 2 via a suction nozzle 12 and a Gripper tube 25. The suction nozzle 12, the upper thread 31 of the Cheese 15 retrieves and in the thread splicer 10 inserts, is limited pivotable about an axis of rotation 16.

Das Greiferrohr 25 zum Handhaben des Unterfadens 32 kann um eine Drehachse 26 verschwenkt werden.The gripper tube 25 for handling the lower thread 32 can order a rotation axis 26 are pivoted.

Die Figuren 2 und 3 zeigen die erfindungsgemäße Fadenspleißvorrichtung 10 jeweils in Draufsicht.Figures 2 and 3 show the inventive Fadensverlißvorrichtung 10 each in plan view.

In Figur 2 ist dabei die Fadenspleißvorrichtung 10 in ihrer Fadenaufnahmestellung I dargestellt, während die Figur 3 die Fadenspleißvorrichtung 10 in ihrer Spleißstellung II zeigt.In Figure 2, the thread splicing device 10 is in her Thread receiving position I shown, while the figure 3 the Fadensverlißvorrichtung 10 in its splice position II shows.

Die Fadenspleißvorrichtung 10 besteht im wesentlichen aus zwei identischen Baugruppen 17, die jeweils an einem Tragarm 11 festgelegt sind. Die Tragarme 11 sind dabei über eine Antriebseinrichtung 18, die lediglich schematisch angedeutet ist, in Richtung Z und Richtung A verstellbar.The yarn splicing device 10 consists essentially of two identical assemblies 17, each on a support arm 11th are fixed. The support arms 11 are over a Drive device 18, which is indicated only schematically is adjustable in direction Z and direction A.

Jede Baugruppe 17 weist einen am Tragarm 11 festgelegten Grundkörper 19 mit einem pneumatisch beaufschlagbaren Anschlußmittel 20 auf. Das Anschlußmittel 20 ist dabei jeweils über eine Pneumatikleitung 22 mit einer (nicht dargestellten) Druckluftquelle verbunden.
Am Grundkörper 19 ist außerdem, über eine Schwenkachse 23 jeweils ein Prismenteil 27 bzw. 28 begrenzt drehbar gelagert. Die Prismenteile 27, 28 besitzen dabei jeweils einen Prismenkörper 27A bzw. 28A sowie ein rückseitiges, lösbar angeordnetes Deckelelement 30.
Das Deckelelement 30 weist eine konvex gewölbte Dichtfläche 33 auf, die mit einer entsprechend konkav gewölbten Dichtfläche 34 des Anschlußmittels 20 korrespondiert.
Wie beispielsweise in Fig.6 angedeutet, ist das Deckelelement 30, beispielsweise über Schraubenbolzen 35, lösbar am Prismenkörper 27A bzw. 28A befestigt.
Each assembly 17 has a fixed to the support arm 11 body 19 with a pneumatically actuated connection means 20. The connecting means 20 is in each case connected via a pneumatic line 22 to a (not shown) compressed air source.
On the base body 19, in addition, a prism portion 27 or 28 is mounted so as to be limitedly rotatable about a pivot axis 23. The prism parts 27, 28 each have a prism body 27A or 28A and a rear, releasably arranged cover element 30.
The cover element 30 has a convexly curved sealing surface 33, which corresponds to a correspondingly concavely curved sealing surface 34 of the connection means 20.
As indicated, for example, in FIG. 6, the cover element 30 is detachably fastened, for example via bolts 35, to the prism body 27A or 28A.

Über die Schraubenbolzen 35 sind außerdem Schwenkhebel 36 festgelegt. Diese Schwenkhebel 36 korrespondieren mit einem entsprechenden Antriebshebel 37 eines (schematisch angedeuteten) Antriebsmittels 38.About the bolts 35 are also pivot lever 36th established. These pivot levers 36 correspond with a corresponding drive lever 37 of a (schematically indicated) drive means 38.

Des weiteren weist jede der Baugruppe 17 eine Reibscheibe 39 auf, die beispielsweise über ein Zahnriemengetriebe antreibbar ist.
In den Figuren 2 und 3 ist von diesem Zahnriemengetriebe lediglich ein Zahnrad 40 angedeutet, über das ein (nicht dargestellter) Zahnriemen geführt ist.
Furthermore, each of the assembly 17 has a friction disk 39, which can be driven, for example, via a toothed belt transmission.
In FIGS. 2 and 3, only a toothed wheel 40 is indicated by this toothed belt transmission, via which a toothed belt (not shown) is guided.

Wie insbesondere aus Fig. 7 ersichtlich, ist in die Prismenkörper 27A, 28A rückseitig jeweils ein Luftverteilungskanal 41 eingearbeitet, von dem Druckluft-Einblasöffnungen 42 abzweigen.
Der Luftverteilungskanal 41 ist dabei mittels des Deckelelementes 30 verschließbar, das im Bereich seiner konvex gewölbten Dichtfläche 33 eine zentrale Luftanschlußbohrung 43 aufweist.
As can be seen in particular from FIG. 7, in each case an air distribution channel 41, from which compressed air injection openings 42 branch off, is incorporated into the prism bodies 27A, 28A at the rear.
The air distribution channel 41 can be closed by means of the cover element 30, which has a central air connection bore 43 in the region of its convexly curved sealing surface 33.

In den Zeichnungen ist allerdings lediglich eine der möglichen Ausführungformen der erfindungsgemäßen Fadenspleißvorrichtung 10 dargestellt.
Das heißt, es sind zahlreiche weitere Varianten denkbar, die jeweils in verschiedenen Details von der dargestellten Ausführungsform abweichen.
Auch diese weiteren Varianten der Fadenspleißvorrichtung 10 verlassen jedoch nicht den der Erfindung zugrunde liegenden allgemeinen Erfindungsgedanken wie er in den Ansprüchen definiert ist.
In the drawings, however, only one of the possible embodiments of the yarn splicing apparatus 10 according to the invention is shown.
That is, there are numerous other variants conceivable, which differ in different details from the illustrated embodiment.
However, these other variants of the yarn splicing device 10 do not rely on the invention underlying general inventive idea as defined in the claims.

Es ist beispielsweise möglich, lediglich eines der Prismenteile 27 oder 28 mit einer Druckluft-Einblasöffnung 42 auszustatten.
In diesem Fall bildet das gegenüberliegende Prismenteil eine Art Deckelelement des Spleißkanals 44.
Bei einer solchen Ausbildung ist selbstverständlich auch nur dasjenige Anschlußmittel 20, in dem das Prismenteil mit der Druckluft-Einblasöffnung 42 gleitet, über eine Pneumatikleitung 22 mit einer (nicht dargestellten) Druckluftquelle verbunden.
It is for example possible to equip only one of the prism parts 27 or 28 with a compressed air injection opening 42.
In this case, the opposite prism part forms a kind of cover element of the splicing channel 44.
In such a configuration, of course, only that connection means 20, in which the prism portion slides with the compressed air injection opening 42, connected via a pneumatic line 22 to a compressed air source (not shown).

In einer weiteren Ausführungsvariante kann außerdem vorgesehen werden, daß lediglich eine der beiden Baugruppen 17, in die die Prismenteile 27, 28 jeweils integriert sind, mittels eines Antriebes 18 in Richtung Z bzw. A verstellbar ist.
In einem solchen Fall ist die gegenüberliegende Baugruppe 17 stationär angeordnet.
In a further embodiment, it may also be provided that only one of the two assemblies 17, in which the prism parts 27, 28 are respectively integrated, is adjustable in the direction Z or A by means of a drive 18.
In such a case, the opposite assembly 17 is arranged stationary.

Des weiteren sind auch Kombinationen der einzelnen Ausführungsvarianten möglich.Furthermore, there are combinations of the individual Variants possible.

Funktion der erfindungsgemäßen, in den Zeichnungen dargestellten Fadenspleißvorrichtung am Beispiel eines Reinigerschnittes:Function of the invention, in the drawings shown yarn splicing device on the example of a Cleaner section:

Während des "regulären" Spulbetriebes steht die erfindungsgemäße Fadenspleißvorrichtung in der in Figur 2 angedeuteten sogenannten Fadenaufnahmestellung II.During the "regular" winding operation is the Thread splicing device according to the invention in the in FIG. 2 indicated so-called thread receiving position II.

Das heißt, die beiden Baugruppen 17 der Fadenspleißvorrichtung 10 sind durch den Antrieb 18 so That is, the two modules 17 of the Thread splicer 10 are so by the drive 18

beaufschlagt, daß die beiden Reibscheiben 39 zueinander beabstandet stehen. Außerdem sind über den Antrieb 38, den Antriebshebel 37 und den Schwenkhebel 36 die Prismenteile 27, 28 im Uhrzeigersinn geschwenkt.acted upon, that the two friction plates 39 to each other stand spaced. In addition, via the drive 38, the Drive lever 37 and the pivot lever 36, the prism parts 27, 28 pivoted clockwise.

Wie bekannt, läuft im Falle eines sogenannten Reinigerschnittes der Oberfaden 31 zunächst auf die Kreuzspule 15 auf, während der Unterfaden 32 üblicherweise in einem Fadenspanner gefangen wird.As is known, runs in the case of a so-called Cleaner section of the upper thread 31 first on the Cross coil 15, while the lower thread 32 usually in a thread tensioner is caught.

Der Oberfaden 31 wird anschließend durch die Saugdüse 12 aufgenommen und durch die nach unten schwenkende Saugdüse 12 zwischen die Prismenteile 27, 28 der Fadenspleißvorrichtung 10 positioniert, wie dies in Figur 1 angedeutet ist.
Anschließend oder gleichzeitig holt das Greiferrohr 25 den Unterfaden 32 vom Fadenspanner ab und positioniert den Unterfaden 32 ebenfalls zwischen den in der Fadenaufnahmestellung I stehenden Prismenteilen 27, 28 der Fadenspleißvorrichtung 10.
The upper thread 31 is then received by the suction nozzle 12 and positioned by the downwardly pivoting suction nozzle 12 between the Prismenteile 27, 28 of the yarn splicing device 10, as indicated in Figure 1.
Subsequently or simultaneously, the gripper tube 25 picks up the lower thread 32 from the thread tensioner and also positions the lower thread 32 between the prism parts 27, 28 of the thread splicing device 10 which are in the thread receiving position I.

Die Fadenspleißvorrichtung 10 wird daraufhin geschlossen.
Das heißt, die Fäden 31, 32 werden zwischen den Reibscheiben 39 der Fadenspleißvorrichtung 10 geklemmt, wie dies in Fig.3 angedeutet ist.
Anschließend werden die Prismenteile 27, 28 mittels des Antriebes 38 im Gegenuhrzeigersinn verschwenkt und bilden dabei zwischen sich einen Spleißkanal 44.
Im Anschluß werden die Fadenenden 31, 32 für den Spleißvorgang vorbereitet.
Das heißt, die Fadenenden 31, 32 werden durch die gegenläufig angetriebenen Reibscheiben 39 wenigstens teilweise von ihrer Garndrehung befreit. Die freien Fadenenden werden dann abgezupft und durch die Saugdüse 12 beziehungsweise das Greiferrohr 25 entsorgt.
Anschließend werden die im Spleißkanal 44 positionierten Fadenenden der Fäden 31, 32 über die Druckluft-Einblasöffnungen 42 mit Spleißluft beaufschlagt und dabei so verwirbelt, daß eine nahezu garngleiche Fadenverbindung entsteht.
The thread splicer 10 is then closed.
That is, the threads 31, 32 are clamped between the friction plates 39 of the yarn splicing device 10, as indicated in Fig.3.
Subsequently, the prism parts 27, 28 are pivoted by means of the drive 38 in the counterclockwise direction and thereby form a splicing channel 44 between them.
Following the thread ends 31, 32 are prepared for the splicing process.
That is, the yarn ends 31, 32 are at least partially freed from their yarn rotation by the oppositely driven friction plates 39. The free thread ends are then removed and disposed of by the suction nozzle 12 and the gripper tube 25.
Subsequently, the yarn ends of the threads 31, 32 positioned in the splicing channel 44 are acted on by the compressed air injection openings 42 with splitting air and thereby swirled so that an almost yarn-like thread connection is formed.

Zum Abschluß werden die Prismenteile 27, 28 aus der Spleißstellung II wieder in die Fadenaufnahmestellung I zurückgedreht, und die Fadenspleißvorrichtung 10 wird wieder geöffnet.
Der jetzt verspleißte Faden kehrt in seinen "normalen" Fadenlaufweg zurück und der Spulprozeß wird fortgesetzt.
Finally, the prism parts 27, 28 are returned from the splicing position II back into the thread receiving position I, and the yarn splicing device 10 is opened again.
The now spliced thread returns to its "normal" thread running path and the winding process continues.
