Abstract

The apparatus has a system (5,5a;6,6a) to give a selective deflection to the leading section (11a) of a correctly positioned weft (11) in the weft insertion channel (2a), forming a separate unit (1a). The system (7,7a;8,10) to guide and detect an incorrectly inserted weft (11) in the insertion channel (2a) forms a second and separate unit (1b), with a single weft monitor (10) for both. The apparatus for detection and stretch of weft yarns, in a jet loom, has a system (5,5a;6,6a) to give a selective deflection to the leading section (11a) of a correctly positioned weft (11) in the weft insertion channel (2a), forming a separate unit (1a). The system (7,7a;8,10) to guide and detect an incorrectly inserted weft (11) in the insertion channel (2a) forms a second and separate unit (1b), which can slide along the reed stay (3) in relation to the first unit (1a). The second unit has two yarn guides (7,8) on different planes, with a single weft monitor (10) for both. A telescopic yarn guide (9) is a connection between at least the deflection guide (6) for the weft (11) at the first unit (1a) and the yarn guide (8) at the second unit (1b). The yarn guide (7) has a biconical entry (7a). A variable gap is between the exit (4a) of the yarn guide (4) and the entry (7a) into the next yarn guide (7). An incorrectly inserted weft (11) bridges the gap without guidance.

Description

Die Erfindung betrifft eine Schussfadenstreck- und -detektiereinrichtung für Düsenwebmaschinen, wobei die Einrichtung ausgangsseitig des Schussfadeneintragkanals eines Webblattes angeordnet ist und zusammen mit dem Webblatt auf der Blattleiste der Webmaschine montiert ist.The invention relates to a weft stretching and detection device for Jet looms, the device on the exit side of the weft insertion channel a reed is arranged and together with the reed on the leaf bar of the Loom is mounted.

Aus der EP 0 716 171 A2 ist eine Schussfadenstreck- und -detektiereinrichtung für Düsenwebmaschinen bekannt, in der in einer technischen Einheit das Schussfadenstrecken erfolgt und in der eventuell auftretende Langschüsse oder Schussfadenbrüche detektiert und das erzeugte Signal einer Webmaschinensteuerung signalübertragend mitgeteilt wird. Der mittels eines strömenden Mediums zu streckende Schussfaden wird dabei aus der Schussfadeneintragsebene, die die erste Anordnungsebene für einen Schussfadenführungskanal in der bekannten Einrichtung bildet, in einen in einer zweiten Anordnungebene liegenden Schussfadenführungskanal gelenkt, was dem Strecken des Schussfadens entspricht. Ist das Schussfadenstrecken deaktiviert, wird der Schussfaden in einen stromabwärts des Schussfadeneintragkanals in der Einrichtung vorhandenen Schussfadenführungskanal eingetragen und gegebenenfalls durch den Luftstrom einer vorhandenen Düseneinrichtung gestreckt, ohne dabei den Schussfaden abzulenken.
Die bekannte Einrichtung besitzt neben ihrem Vorteil, wonach die Position der Schussfadenwächter in den beiden Anordnungsebenen entsprechend dem Längendehnungsverhalten der Schussfäden festlegbar ist, den Nachteil, dass jede Anordnungsebene jeweils einen Schussfadenwächter erfordert und dass wegen der im Vergleich zum Schussfadeneintragskanal des Webblattes ungünstigeren Luftströmungsverhältnisse des in der ersten Anordnungsebene liegenden Schussfadenführungskanals eine zusätzliche nicht dargestellte Düseneinrichtung zum Strecken des Schussfadens notwendig ist.EP 0 716 171 A2 discloses a weft stretching and detection device for jet looms in which the weft stretching takes place in a technical unit and in which any long weft or weft breakage is detected and the signal generated is communicated to a weaving machine control system in a signal-transmitting manner. The weft thread to be stretched by means of a flowing medium is directed from the weft thread insertion level, which forms the first arrangement level for a weft thread guide channel in the known device, into a weft thread guide channel lying in a second arrangement level, which corresponds to the stretching of the weft thread. If the weft thread stretching is deactivated, the weft thread is inserted into a weft thread guide channel present in the device downstream of the weft thread insertion channel and, if necessary, stretched by the air flow of an existing nozzle device without deflecting the weft thread.
The known device has, in addition to its advantage, according to which the position of the weft monitor in the two arrangement levels can be determined in accordance with the elongation behavior of the weft, the disadvantage that each arrangement level requires a weft monitor and that because of the less favorable air flow conditions in comparison to the weft insertion channel of the reed an additional nozzle device (not shown) for stretching the weft thread is necessary on the first arrangement level of the weft thread guide channel.

Aufgabe der Erfindung ist es, eine Einrichtung zum wahlweise umlenkenden Strecken und Detektieren des in das Webfach einer Webmaschine inkorrekt eingetragenen Schussfadens zu schaffen, die gegenüber der aus dem Stand der Technik bekannten Einrichtung einen einfacheren Aufbau besitzt, eine höhere Funktionssicherheit erreicht und leichter handhabbar ist.The object of the invention is to provide a device for optionally deflecting stretching Detect the weft thread incorrectly entered in the shed of a weaving machine create one over the device known from the prior art has a simpler structure, achieves greater functional reliability and is easier to handle is.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.
Ein wesentliches Merkmal ist danach, dass die Schussfadenstreck- und -detektiereinrichtung aus einer ersten technischen Einheit besteht, die das umlenkende Strecken des Schussfadens bewirkt, und aus einer zweiten technischen Einheit besteht, die relativ zur ersten technischen Einheit auf der Blattleiste der Webmaschine zusammen mit einem einzigen Schussfadenwächter verschiebbar angeordnet ist, wobei der Schussfadenwächter die Ankunft eines inkorrekten Schussfadens überwacht und ein entsprechendes elektrisches Signal einer nicht dargestellten Webmaschincnsteuereinheit mitteilt.The object is achieved by the features of claim 1.
An essential feature is that the weft stretching and detection device consists of a first technical unit, which effects the deflecting stretching of the weft thread, and of a second technical unit, which is relative to the first technical unit on the sheet bar of the weaving machine together with one is arranged displaceably, the weft monitor monitors the arrival of an incorrect weft and notifies a corresponding electrical signal to a weaving machine control unit (not shown).

Von Vorteil ist, dass die Einrichtung lediglich einen Schussfadenwächter erfordert, dass die Einrichtung auf den mittleren Abschnitt des in der ersten Anordnungsebene vorhandenen Fadenführungskanals der bekannten Einrichtung verzichtet, wodurch die erfindungsgemäße Einrichtung masseärmer ist, und dass schließlich mit nur einem einzigen Verstellvorgang die zweite technische Einheit, die einen einzigen Schussfadenwächter besitzt, dem Längenstreckverhalten der Schussfäden relativ schnell angepasst werden kann.
Ferner sei erwähnt, dass im Rahmen von Funktionserprobungen der erfindungsgemäß ausgebildeten Einrichtung erkannt wurde, dass mit dem Verzicht auf den mittleren Abschnitt des sich in der ersten Anordnungsebene erstreckenden Fadenführungskanals keine Beeinträchtigung des Schussfadenfluges einhergeht.
Vielmehr ist die Größe der den Schussfaden beschleunigenden Energie noch ausreichend, um im Falle eines Schussfadenbruches die abgerissene Schussfadenlänge in der ersten oder zweiten Anordnungsebene der zweiten technischen Einheit zu detektieren.It is advantageous that the device only requires a weft monitor, that the device dispenses with the central section of the thread guide channel of the known device in the first arrangement level, as a result of which the device according to the invention is lighter in mass, and that, finally, the second technical unit is carried out with only one adjustment process , which has a single weft monitor, the length extension behavior of the weft can be adjusted relatively quickly.
It should also be mentioned that in the course of functional tests of the device designed according to the invention, it was recognized that the omission of the central section of the thread guide channel extending in the first arrangement level does not impair the weft thread flight.
Rather, the size of the energy accelerating the weft thread is still sufficient to detect the torn-off weft thread length in the first or second arrangement level of the second technical unit in the event of a weft thread breakage.

In Ausgestaltung der erfindungsgemäßen Lösung ist der Eingang des in der ersten Anordnungsebene liegenden Schussfadenführungskanals bikonisch ausgebildet. Damit wird gewährleistet, dass der betreffende Schussfaden ungehindert in den Schussfadenführungskanal der zweiten technischen Einheit eintreten kann. In an embodiment of the solution according to the invention, the input is in the first Arrangement level lying weft guide channel biconical. So that will ensures that the weft concerned in the The second technical unit can enter the weft guide channel.

In weiterer Ausgestaltung der erfindungsgemäßen Lösung ist der in der zweiten Anordnungsebene liegende Ausgang der zweiten Fadenführung und der Eingang der in der zweiten Anordnungsebene liegenden Fadenführung der zweiten technischen Einheit, wie an sich bekannt, durch eine längenveränderliche Fadenführung verbunden.In a further embodiment of the solution according to the invention is that in the second Output level of the second thread guide and the input of the in the second arrangement level thread guide of the second technical unit, as at known, connected by a variable-length thread guide.

Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels erläutert.The invention is illustrated below with reference to one in the drawings Exemplary embodiment explained.

Gemäß den Figuren 1 bis 3 besteht die Schussfadenstreck- und -detektiereinrichtung nicht, wie aus dem Stand der Technik bekannt, aus einer in einem gemeinsamen, mit der Blattleiste der Webmaschine verbundenen Baueinheit mit integrierten Einrichtungen zum Strecken und Detektieren eines Schussfadens, sondern erfindungsgemäß aus einer ersten separaten technischen Einheit 1a mit Mitteln 4, 5, 5a und 6, 6a, 6b zum Strecken eines korrekt in den Schussfadeneintragskanal 2a eines Webblattes 2 eingetragenen Schussfadens 11 und aus einer zweiten separaten technischen Einheit 1b mit Mitteln 10 zum Führen und Detektieren eines inkorrekt in den Schussfadeneintragskanal 2a des Webblattes 2 eingetragenen Schussfadens 11, wobei beide technischen Einheiten stromabwärts des Schussfadeneintragkanals angeordnet sind und die zweite technische Einheit 1b relativ zur ersten technischen Einheit 1a auf der Blattleiste 3 einstellbar ist.
Zum Detektieren des inkorrekten Schussfadens ist für beide Fadenführungen 4 und 6 lediglich ein Schussfadenwächter 10 vorgesehen.
Gegenüber dem eingangs erwähnten Stand der Technik kann gemäß Figur 1 die anmeldungsgemäße Schussfadenstreck- und -detektiereinrichtung 1 in der ersten Anordnungsebene auf eine Fadenführung zwischen der ersten technischen Einheit 1a, also der Schussfadenstreckeinrichtung, und der zweiten technischen Einheit, also der Schussfadendetektiereinrichtung, verzichten.According to FIGS. 1 to 3, the weft stretching and detection device does not, as is known from the prior art, consist of a unit in a common unit connected to the sheet bar of the weaving machine with integrated devices for stretching and detecting a weft thread, but according to the invention consists of one first separate technical unit 1a with means 4, 5, 5a and 6, 6a, 6b for stretching a weft 11 correctly inserted into the weft insertion channel 2a of a reed 2 and from a second separate technical unit 1b with means 10 for guiding and detecting an incorrectly in the weft insertion channel 2a of the reed 2 inserted weft 11, both technical units being arranged downstream of the weft insertion channel and the second technical unit 1b being adjustable relative to the first technical unit 1a on the sheet bar 3.
In order to detect the incorrect weft thread, only one weft thread monitor 10 is provided for both thread guides 4 and 6.

In der zweiten Anordnungsebene hingegen kann die zwischen der technischen Einheit 1a und der technischen Einheit 1b liegende Fadenführung 9, wie an sich bekannt, als Teleskoprohr ausgebildet sein.
Wenn in der ersten Anordnungsebene zwischen der ersten technischen Einheit 1a und der zweiten technischen Einheit 1b auf eine Fadenführung verzichtet wird, ist in weiterer Ausgestaltung der Erfindung der Eingang 7a der Fadenführung 7 bikonisch ausgebildet. Der einzige, beide Anordnungsebenen in der technischen Einheit 1b überwachende Schussfadenwächter 10 kann ein allgemein bekannter Schussfadenwächter sein, so dass hierauf nicht näher eingegangen werden muss.In the second arrangement level, however, the thread guide 9 lying between the technical unit 1a and the technical unit 1b can, as is known per se, be designed as a telescopic tube.
If a thread guide is dispensed with in the first arrangement level between the first technical unit 1a and the second technical unit 1b, the input 7a of the thread guide 7 is biconical in a further embodiment of the invention. The only weft monitor 10 monitoring both arrangement levels in the technical unit 1b can be a generally known weft monitor, so that there is no need to go into this in greater detail.

Die relativ zur ersten technischen Einheit 1a verstellbare zweite technische Einheit 1b ist in Figur 3 dargestellt. Die technische Einheit 1b ist in gleicher Weise wie die technische Einheit 1a mit der Blattleiste 3 verbunden.
Die bikonische Gestaltung des Eingangs 7a der Fadenführung 7 ist hier deutlich sichtbar. Die relative Verstellbarkeit der technischen Einheit 1b ist in Figur 1 mittels des Doppelpfeiles 12 angedeutet. The second technical unit 1b, which is adjustable relative to the first technical unit 1a, is shown in FIG. The technical unit 1b is connected to the sheet bar 3 in the same way as the technical unit 1a.
The biconical design of the entrance 7a of the thread guide 7 is clearly visible here. The relative adjustability of the technical unit 1b is indicated in FIG. 1 by means of the double arrow 12.
