Abstract
Description
Die Erfindung betrifft eine Schußfadeneintragsvorrichtung für eine Luftdüsenwebmaschine
nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a weft insertion device for an air jet loom
according to the preamble of
Bei den für Luftdüsenwebmaschinen bekannten Schußfadeneintragsvorrichtungen wird der Hauptblasdüsenblock, der auf der Weblade angeordnet ist, über flexible Druckleitungen mit Druckluft versorgt. Die Luftversorgung der Einzelblasdüsen erfolgt über Verteileranordnungen, die fest am Maschinenrahmen angeordnet und über die besagten Druckleitungen mit den einzelnen Blasdüsen verbunden sind. Da der Hauptblasdüsenblock auf der Weblade angeordnet ist und folglich die oszillierenden Schwenkbewegungen zusammen mit der Weblade ausführt, müssen die Druckleitungen zwischen Verteilerblock und Hauptblasdüseblock eine gewisse Länge aufweisen, damit bei jeder Stellung der Weblade eine störungsfreie Luftzufuhr zum Hauptblasdüsenblock sichergestellt ist. Dabei kann sich z.B. durch Knicken der flexiblen Druckleitungen zeitweilig deren Querschnitt bei jeder Bewegung der Weblade ändern, wobei mit jeder Querschnittsveränderung ein entsprechender Verschleiß einhergeht. Zudem war es bisher aufgrund der relativ langen Druckleitungen und der begrenzten Platzverhältnisse schwierig, die Druckleitungen überkreuzungsfrei zu führen und sie gleichzeitig möglichst kurz zu halten. Bei einer gewissen Länge der Druckleitungen besteht jedoch das Problem, daß sich der Druckaufbau bis zum Hauptblasdüsenblock verzögert bzw. ein Druckverlust auftritt, der durch Vergrößerung des Durchmessers der Druckleitungen oder durch steuerungstechnische Maßnahmen korrigiert werden muß.In the weft insertion devices known for air jet weaving machines, the Main blowing nozzle block, which is arranged on the sley, via flexible pressure lines supplied with compressed air. The air supply to the individual blowing nozzles takes place via Distribution arrangements, which are fixed to the machine frame and above said Pressure lines are connected to the individual blow nozzles. Because the main blow nozzle block is arranged on the sley and consequently the oscillating pivoting movements together with the sley, the pressure lines between the manifold and main blow nozzle block have a certain length, so that the Weblade ensures a trouble-free air supply to the main blow nozzle block. there can e.g. temporarily bending the cross-section of the flexible pressure lines change with every movement of the sley, with each change in cross-section corresponding wear and tear. In addition, it was previously due to the relatively long Pressure lines and the limited space difficult, the pressure lines to lead without crossing and at the same time keep it as short as possible. At a certain length of the pressure lines, however, there is the problem that the pressure build-up Delayed to the main blow nozzle block or a pressure loss that occurs through Increase the diameter of the pressure lines or by control technology Measures must be corrected.
Ein System mit verbesserter Luftzufuhr zum Hauptblasdüsenblock ist in der EP 619 391 B1 beschrieben. Hierbei werden die Druckleitungen zwischen dem Verteilerblock und dem Hauptblasdüsenblock kurz gehalten, indem der Verteilerblock etwa mittig zwischen den Endpositionen der Bewegung der Weblade angeorndet ist mit welcher Weblade der Hauptblasdüsenblock die Schwenkbewegung ausführt. Dadurch kann die mechanische Beanspruchung der Leitungen und der Druckverlust verringert werden. A system with improved air supply to the main blow nozzle block is in the EP 619 391 B1. Here, the pressure lines between the Manifold block and main blow nozzle block kept short by the manifold block is arranged approximately midway between the end positions of the movement of the sley which sley the main blowing nozzle block performs the swiveling movement. This can the mechanical stress on the lines and the pressure loss are reduced.
Bei einem Hauptblasdüsenblock mit einem Vorblasdüsenblock ist es jedoch nach wie vor schwierig, die Vielzahl der einzelnen Druckleitungen auf kürzestem Weg überkreuzungsfrei und ohne Knickstellen zwischen dem Verteilerblock und den betreffenden Blasdüsenblöcken zu führen.However, it is still the same with a main blow nozzle block with a pre-blow nozzle block difficult, the multitude of individual pressure lines by the shortest route crossover-free and without kinks between the distributor block and the to lead the relevant blow nozzle blocks.
Der Erfindung liegt deshalb die Aufgabe zugrunde, die Schußfadeneintragsvorrichtung für Luftdüsenwebmaschinen der eingangs beschrieben Art zu verbessern.The invention is therefore based on the object, the weft insertion device for To improve air jet weaving machines of the type described at the beginning.
Die Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.The object is achieved by the characterizing features of
Die Erfindung beruht darauf, daß der oder die Verteilerblöcke so angeordnet sind, daß sie den Hauptblasdüsenblock unabhängig von der Stellung der Weblade wenigstens teilweise umgeben.The invention is based on the fact that the distributor block or blocks are arranged so that they the main blowing nozzle block at least partially regardless of the position of the sley surround.
Dadurch, daß die Eingänge für die Einzelblasdüsen des Hauptblasdüsenblockes vorteilhaft verteilt über den Umfang des Hauptblasdüsenblockes angeordnet sind und die Ausgänge des Verteilerblocks erfindungsgemäß direkt gegenüber dem zugeordneten Eingang angeordnet werden können, ergibt sich der Vorteil, daß die Länge der Druckleitungen zwischen dem Ausgang und dem Eingang auf ein Minimum reduziert werden kann. Außerdem ist es möglich, die Druckleitungen in einfacher Weise überkreuzungsfrei zu führen, so daß die einzelnen Leitungen im Webbetrieb nicht aneinander reiben. Ein weiterer Vorteil besteht darin, daß durch die erfindungsgemäße Anordnung der Verteilerblöcke alle Druckleitungen im wesentlichen die gleiche Länge aufweisen, so daß die Verzögerungszeiten für den Druckaufbau bis zum Hauptblasdüsenblock gleich groß sind.Characterized in that the inputs for the individual blow nozzles of the main blow nozzle block advantageous distributed over the circumference of the main blow nozzle block and the exits of the distributor block according to the invention directly opposite the assigned input can be arranged, there is the advantage that the length of the pressure lines between the exit and the entrance can be reduced to a minimum. It is also possible to easily cross the pressure lines without crossing lead so that the individual lines do not rub against each other during weaving. Another advantage is that the arrangement of the invention Manifold blocks all have pressure lines of essentially the same length, so that the delay times for the pressure build-up to the main blow nozzle block are the same are.
In einer ersten Ausführungsform sind mehrere einzelne Verteilerblöcke vorhanden, die etwa L-förmig oder U-förmig um den Hauptblasdüsenblock angeordnet sind. Dabei können die einzelnen Verteilerblöcke in einer Ebene senkrecht zur Längsachse der Weblade angeordnet sein, oder aber in Richtung der Längsachse der Weblade räumlich zueinander versetzt sein. Die versetzte Anordnung bietet zum Beispiel beim Einsatz einer sogenanntenTandemanordnung von Vordüse und Hauptdüse den Vorteil, daß beide Düsen über relativ kurze Druckleitungen mit Druckluft versorgt werden können.In a first embodiment, there are several individual distribution blocks that are arranged approximately L-shaped or U-shaped around the main blow nozzle block. there can the individual manifold blocks in a plane perpendicular to the longitudinal axis of the The sley should be arranged, or spatially in the direction of the longitudinal axis of the sley be offset from each other. The offset arrangement offers, for example, when using a so-called tandem arrangement of pre-nozzle and main nozzle the advantage that both nozzles can be supplied with compressed air via relatively short pressure lines.
Gemäß einer weiteren Ausführungsform ist der Verteilerblock als Kreisbogen oder U-förmig ausgebildet, wobei die Ausgänge in gleichmäßigen oder veränderlichen Abständen zueinander auf dem Kreisbogen oder der U-Form des Verteilerblocks angeordnet sind.According to a further embodiment, the distributor block is in the form of a circular arc or U-shaped trained, the outputs at regular or variable intervals are arranged to each other on the circular arc or the U-shape of the distributor block.
In bekannter Weise ist jedem Ausgang des Verteilerblocks ein steuerbares Ventil zugeordnet, so daß die Luftzufuhr zu jeder Einzelblasdüse geregelt werden kann.In a known manner, each outlet of the distributor block is a controllable valve assigned so that the air supply to each individual blowing nozzle can be regulated.

In Figur 1 ist ein Hauptblasdüsenblock 2 dargestellt, welcher mehrere, im Beispiel
insgesamt acht, Einzelblasdüsen 3 aufweist, die in zwei Reihen zu je vier Düsen
nebeneinander angeordnet sind. Jeder Einzelblasdüse 3 ist ein Eingang 4 zugeordnet, über
den die Düse mit Druckluft versorgt wird. Um eine gute Zugänglichkeit zu den Eingängen
4 zu gewährleisten, sind diese in geeigneter Weise über den Umfang des
Hauptblasdüsenblockes 2 verteilt angeordnet. In Figure 1, a main
Der Hauptblasdüsenblock 2 ist mittels nicht dargestellten Verbindungselementen fest mit
der Weblade 5 verbunden, die hier nur schematisch angedeutet ist. Im Betrieb der
Webmaschine bewegt sich die Weblade 5 um die Längsachse 6 abwechselnd zwischen
zwei Endpositionen 8,9, nämlich zwischen der Schußfadeneintragsposition 8 und der
Schußfadenanschlagsposition 9 hin und her. Die Bewegungsrichtung ist durch den
Doppelpfeil 7 angedeutet. Zusammen mit der Weblade 5 bewegt sich auch der
Hauptblasdüsenblock 2 zwischen den Endpositionen 8, 9 hin und her.The main
Die Schußfadeneintragsvorrichtung 1 umfasst ferner mehrere Verteilerblöcke 10, 13 und
16, die außerhalb des Arbeitsbereiches der Weblade 5 etwa U-förmig um den
Hauptblasdüsenblock 2 angeordnet sind. Durch diese Verteilerblöcke 10, 13, 16 werden
die Einzelblasdüsen 3 mit Druckluft versorgt.The
Jeder Verteilerblock 10, 13, 16 besitzt eine Hauptluftzufuhr 11, 14 und 17 über welche er
mit Druckluft versorgt wird. Die Druckluft strömt in einem Kanal innerhalb des
Verteilerblockes 10, 13, 16 und wird auf mehrere Ausgänge 12, 15 und 18 verteilt. Jeder
Ausgang 12, 15, 18 ist über ein Ventil, z.B. ein Magnetventil, individuell ansteuerbar. Im
vorliegenden Beispiel sind die Ausgänge 12, 15, 18 der Verteilerblöcke 10, 13, 16 in einer
Reihe nebeneinander angeordnet. Es sind jedoch auch zweireihige Anordnungen denkbar.Each
Die Ausgänge 12, 15, 18 der Verteilerblöcke 10, 13, 16 sind jeweils über eine flexible
Druckleitung 19 mit einem zugeordneten Eingang 4 der Einzelblasdüsen 3 verbunden.
Jeder Eingang 4 der Einzelblasdüsen 3 wird erfindungsgemäß von demjenigen
Verteilerblock versorgt, dessen Ausgang dem Eingang der Düse möglichst direkt
gegenüber liegt, d.h. die Eingänge 4 im oberen Bereich des Hauptblasdüsenblockes 2
werden vom oberen Verteilerblock 13 versorgt, während z.B. die Eingänge 4 im linken
Bereich des Hauptblasdüsenblockes 2 vom linken Verteilerblock 10 versorgt werden.
Dadurch kann die Länge der Druckleitungen 19 sehr kurz gehalten werden, wobei man
sich bei der Längenbemessung an jeweils der dem entsprechenden Verteilerblock 10, 13,
16 entfernt liegenden Endstellung 8 oder 9 der Weblade 5 orientiert. The
Wird gemäß Figur 4 eine sogenannte Tandem-Düsenanordnung verwendet, bestehend aus
einer Vordüse 29 und einer Hauptdüse 28, so ist es vorteilhaft, die einzelnen
Verteilerblöcke 30, 31 in Richtung der Längsachse 6 der Weblade 5 räumlich versetzt
anzuordnen. Der Verteilerblock 30 dient dabei zur Versorgung der Vordüse 29 und der
Verteilerblock 31 zur Versorgung der Hauptdüse 28. So kann die Länge der einzelnen
Druckleitungen 32 kurz gehalten werden. Es kann ferner vorgesehen sein, einen weiteren
Verteilerblock gegenüber dem Verteilerblock 31 direkt neben den Blasdüsen 28, 29
anzuordnen, und zwar derart, wie es in Figur 1 gezeigt ist.According to FIG. 4, a so-called tandem nozzle arrangement is used, consisting of
a pre-nozzle 29 and a
Figur 2 zeigt ein weiteres Ausführungsbeispiel der Schußfadeneintragsvorrichtung. Dabei
wird lediglich ein Verteilerblock 20 verwendet, der in Form eines Kreisbogens um den
Hauptblasdüsenblock 2 angeordnet ist. Der Verteilerblock 20 besitzt eine Hauptluftzufuhr
21. Der Verteilerblock 20 verteilt die zugeführte Druckluft auf mehrere Ausgänge 22, die
vorzugsweise in regelmäßigen Abständen zueinander auf dem durch den Verteilerblock 20
gebildeten Kreisbogen angeordnet sind. Somit gibt es für jeden Eingang 4 der
Einzelblasdüsen 3 des Hauptblasdüsenblockes 2 mindestes einen Ausgang 22 des
Verteilerblocks 20, der diesem Eingang 4 in einer der beiden Endpositionen 8,9 der
Weblade 5 am nächsten liegt. Vorzugsweise wird genau dieser Ausgang 22 über eine
flexible Druckleitung 23 mit dem zugeordneten Eingang 4 der Einzelblasdüse 3
verbunden. Dadurch kann die Länge der Druckleitungen 23 sehr kurz gehalten werden,
wobei man sich bei der Längenbemessung wiederum an jeweils der dem gewählten
Ausgang 22 entfernt liegenden Endposition 8 oder 9 der Weblade 5 orientiert.Figure 2 shows a further embodiment of the weft insertion device. there
only a
Schließlich ist in Figur 3 eine weitere Ausführung der Schußfadeneintragsvorrichtung
dargestellt. Es ist ein einziger Verteilerblock 24 vorhanden, der von einer Hauptluftzufuhr
25 gespeist wird und aus mehreren, miteinander verbundenen Einzelelementen besteht.
Dadurch wird eine annähernd kreisbogenförmige Ausbildung des Verteilerblocks 24
erreicht. Die Ausgänge 26 zur Luftversorgung des Hauptblasdüsenblockes 2 können
beliebig und in geeigneter Weise auf die Einzelelemente verteilt sein. Im Beispiel sind im
oberen Bereich des Verteilerblocks 24 vier Ausgänge 26 und in den beiden
Seitenbereichen jeweils zwei Ausgänge 26 vorgesehen. Zur Luftversorgung des
Hauptblasdüsenblockes 2 werden nun in oben beschriebener Weise den Eingängen 4 der
Einzelblasdüsen 3 möglichst die nächstliegenden Ausgänge 26 des Verteilerblocks 24
zugeordnet und über eine Druckleitung 27 verbunden, wobei auch bei der
Längenbemessung der Druckleitungen 27 wie in den Beispielen gemäß Figur 1 und Figur
2 verfahren wird. Finally, in Figure 3 is another embodiment of the weft insertion device
shown. There is a
