Abstract

Die vorliegende Erfindung betriffl eine Schußeintragungsvorrichtung (10) für Webmaschinen mit schwenkbaren Blasdüsen (18). Sowohl die Schußeintragungsvorrichtungen mit schwenkbaren, als auch mit ortsfesten Blasdüsen arbeitenden Webmaschinen besitzen ihre Nachteile. Insbesondere sind die Schwenkmechanismen des Standes der Technik relativ wartungsanfällig und erfordern häufig ein Verschwenken in mehreren Richtungen. Gerade bei den äußerst hohen Umdrehungszahlen pneumatischer Webmaschinen, treten deswegen häufig Schwierigkeiten bei der schnellen Versetzung der Blasdüsen zwischen den unwirksamen und wirksamen Schußpositionen auf. Letzteres gilt insbesondere, wenn sechs oder mehr Blasdüsen auf der Weblade befestigt werden. Die Erfindung schafft hier Abhilfe von derartigen Problemen dadurch, dass sie nicht nur den Düsenkörper (13) schwenkbar am Schwenkpunkt lagert, sondern gleichzeitig die Blasdüsen (18) im vorderen Bereich auf einem oder mehreren pneumatischen Zylindern (35A, 34B) vertikal schwenkbar lagert und auf der gegenüberliegenden Seite der Blasdüsen (18) zur Abfederung Druckfedern (35) vorsieht, so daß die jeweiligen Schußlängen aus den gewünschten Blasdüsen (18) in den U-förmigen Kanal (14) eintreten.The present invention relates to a weft insertion device (10) for weaving machines with pivotable blowing nozzles (18). Both the weft insertion devices with pivoting weaving machines and with stationary blowing nozzles have their disadvantages. In particular, the swivel mechanisms of the prior art are relatively maintenance-prone and often require swiveling in several directions. Especially with the extremely high number of revolutions of pneumatic weaving machines, difficulties often arise with the rapid displacement of the blowing nozzles between the ineffective and effective weft positions. The latter applies in particular if six or more blowing nozzles are attached to the sley. The invention remedies such problems in that it not only supports the nozzle body (13) in a pivotable manner at the pivot point, but at the same time supports and supports the blowing nozzles (18) in the front area on one or more pneumatic cylinders (35A, 34B) the opposite side of the blowing nozzles (18) provides compression springs (35) for cushioning, so that the respective shot lengths from the desired blowing nozzles (18) enter the U-shaped channel (14).

Description

Die vorliegende Erfindung betrifft eine Schußeintragungsvorrichtung für Webmaschinen nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum pneumatischen Eintragen gemäß dem Oberbegriff des Patentanspruchs 4.The present invention relates to a weft insertion device for weaving machines according to the preamble of claim 1 and a method for pneumatic insertion according to the preamble of claim 4.

Im Stand der Technik sind verschiedene Schußeintragungsvorrichtungen für Webmaschinen und entsprechende Verfahren bekanntgeworden. Bei mit ortsfesten Blasdüsen arbeitenden Schußeintragungsvorrichtungen ist die Anzahl der Blasdüsen aufgrund der ihnen eigenen Größen- und Abstandsverhältnisse relativ beschränkt, da sämtliche Blasdüsen zu jeglicher Zeit eine wirksame Schußeintragungsposition zum U-förmigen Tunnel des Rietes oder einem anderen Luftführungssystem (Konfusor) besitzen müssen. Bei schwenkbaren Blasdüsen ist ihre Anzahl insofern kritisch, als daß bei steigender Zahl der Schwenkweg länger wird und die Geschwindigkeit bei den ohnehin kurzen Zeitspannen aufeinanderfolgender Webzykli dann gesteigert werden muß, was nicht nur zu Verschleißerscheinungen und damit zu größerer Wartungsanfälligkeit führt, sondern auch ungenauen Eintragspositionen.Various weft insertion devices for weaving machines and corresponding methods have become known in the prior art. In the case of weft insertion devices which work with stationary blower nozzles, the number of blower nozzles is relatively limited due to their inherent size and spacing ratios, since all of the blower nozzles must have an effective weft insertion position at all times with respect to the U-shaped tunnel of the reed or with another air guidance system (confuser). In the case of swiveling blow nozzles, their number is critical insofar as the number of swivels becomes longer as the number increases and the speed then has to be increased in the anyway short periods of time of successive weaving cycles, which not only leads to signs of wear and tear and thus to greater susceptibility to maintenance, but also inaccurate entry positions.

Der Erfindung liegt deshalb die Aufgabe zugrunde, die eingangs genannte Schußeintragungsvorrichtung derart zu verbessern, daß sie eine einwandfreie, wartungsunanfällige Arbeitsweise bei vier, sechs oder mehr Blasdüsen unter Vermeidung der genannten Nachteile des genannten Standes der Technik sicherstellt.The invention is therefore based on the object of improving the weft insertion device mentioned at the outset in such a way that it ensures flawless, maintenance-insensitive operation with four, six or more blowing nozzles while avoiding the disadvantages of the prior art mentioned.

Die vorstehende Aufgabe wird erfindungsgemäß durch die im Anspruch 1 gekennzeichnete Schußeintragungsvorrichtung gelöst. Danach werden vier, sechs oder mehr Blasdüsen paarweise horizontal eng benachbart vor dem U-förmigen Kanal oder einem anderen Luftführungssystem (Konfusor) des Rietbalkens angeordnet undes Verschwenken oder ein Drehen des Düsenkörpers überflüssig wird.The above object is achieved according to the invention by the weft insertion device characterized in claim 1. Four, six or more blowing nozzles are then arranged horizontally in close proximity in pairs in front of the U-shaped channel or another air guidance system (confuser) of the reed beam, and pivoting or turning of the nozzle body is unnecessary.

Von erfindungsgemäßer Bedeutung ist ferner die Tatsache, daß die Blasdüsen im vorderen Bereich auf einem oder mehreren pneumatischen Zylindern, die nebeneinander oder hintereinander angeordnet sein können, gelagert sind. Sie bewirken durch übliche Ansteuerung das eigentliche Verschwenken der Düsen, wobei auf der gegenüberliegenden Seite eine entsprechende Anzahl von Druckfedern vorgesehen ist, die als Federungs- bzw. Gegenkraft wirken, um unerwünschte Schwingungen zu dämpfen bzw. die präzise Eintragung des gewünschten Schußfadens gewährleisten.Of further importance according to the invention is the fact that the blowing nozzles are mounted in the front area on one or more pneumatic cylinders, which can be arranged side by side or one behind the other. They effect the actual pivoting of the nozzles by conventional control, with a corresponding number of compression springs being provided on the opposite side, which act as a suspension or counterforce in order to dampen undesired vibrations or ensure the precise entry of the desired weft thread.

Weitere Vorteile und Merkmale gehen aus den vorstehenden Unteransprüchen hervor, die einzeln oder auch gemeinsam von erfinderungsgemäßer Bedeutung sein können.Further advantages and features emerge from the preceding subclaims, which individually or together can be of importance according to the invention.

Im folgenden wird ein bevorzugtes Ausführungsbeispiel anhand der Zeichnung näher beschrieben. Es zeigt:

  • Fig. 1 eine perspektivische Schemaansicht der erfindungsgemäßen Schußeintragungsvorrichtung.
A preferred exemplary embodiment is described in more detail below with reference to the drawing. It shows:
  • Fig. 1 is a perspective schematic view of the weft insertion device according to the invention.

In Fig. 1 ist die erfindungsgemäße Schußeintragungsvorrichtung für Webmaschinen mit schwenkbaren Blasdüsen allgemein mit 10 bezeichnet. Der besseren Ubersicht halber ist die Webmaschine nicht in ihrer Gesamtheit gezeigt, damit die erfindungsgemäßen Details besser erkennbar sind. Die Haupt- bzw. Blasdüsen 18 sind über den Düsenkörper 13 an ihrem hinteren Ende mit der Weblade 26 verbunden. Die vertikale Schwenkbartkeit der Blasdüsen 18 erfolgt dabei um den Schwenkpunkt 36 des Düsenkörpers 13. Jede einzelne der sechs gezeigten Blasdüsen 18 besitzt eine eigene Speicher- bzw. Ablängungsvorrichtung (nicht gezeigt). Die einzutragenden sechs Schußfäden sind mit 32 bezeichnet. Jede der rohrförmigen Düsen 18 besitzt eine eigene Druckluftleitung 19, die jeweils mit entsprechenden Druckluftbehältern (nicht gezeigt) verbunden sind.In Fig. 1, the weft insertion device according to the invention for weaving machines with pivotable blowing nozzles is generally designated 10. View of the better U over half of the weaving machine is not shown in its entirety, so that the details according to the invention can be better recognized. The main or blowing nozzles 18 are connected to the sley 26 at their rear end via the nozzle body 13. The vertical swiveling of the blow nozzles 18 takes place around the pivot point 36 of the nozzle body 13. Each of the six blow nozzles 18 shown has its own storage or cutting device (not shown). The six weft threads to be entered are designated 32. Each of the tubular nozzles 18 has its own compressed air line 19, which are each connected to corresponding compressed air tanks (not shown).

Von besonderer erfindungsgemäßer Bedeutung ist die Halterung 52, welche die Blasdüsen 18 in ihrem vorderen Bereich zusammenfaßt und wiederum mit der Weblade 26 verbindet. Auf der Grundfläche 38 dieser Halterung 52 sind zwei pneumatische Zylinder 34a und 34b hintereinander und unterhalb der Blasrohre 18 angeordnet. Sie stehen in Kontakt mit zwei die Blasdüsen 18 umgebenden Klammern 37, welche die Rohre bündelmäßig zusammenfassen. Oberhalb der Klammern 37 sind jeweils eine Druckfeder 35 angeordnet, die als Gegenkraft mit den pneumatischen Zylindern 34a und 34b zusammenwirken, da sie zwischen den Klammern 37 und der Halterung 52 eingespannt sind. Die Anzahl und Anordnung der pneumatischen Zylinder 34 und der Druckfeder 35 ist nicht kritisch, sondern kann im geeigneten Rahmen gewählt werden, solange sichergestellt ist, daß ein einwandfreies und präzises Verschwenken der rohrförmigen Blasdüsen 18 gewährleistet ist, so daß die jeweiligen Schußlängen 32 aus den gewünschten Blasdüsen 18 in den U-förmigen Kanal 14 des Rietes 16 eintreten können. Deutlicher ist dieses links unten in Fig. 1 im Querschnitt gezeigt, wo die Öffnungen 1 und 2 der obersten Blasdüsen 18 in Einschußposition für den U-förmigen Kanal 14 des Rietes 16 liegen, während die mittleren Öffnungen 3 und 4 und die unteren Öffnungen 5 und 6 der Blasdüsen 18 unterhalb der Eintragsposition liegen und sich deshalb in Ruhestellung befinden. Erst durch ein vertikales Verschwenken der Blasdüsen 18 über den Schwenkpunkt 36 mittels der pneumatischen Zylinder 34a und b können die mittleren bzw. unteren Blasdüsen 18 mit ihren Öffnungen 3 und 4 bzw. 5 und 6 in die gewünschte Schußposition gebracht werden. Die Steuerung für die pneumatischen Zylinder ist nicht gezeigt, da sie für den Fachmann auf der Hand liegt.Of particular importance according to the invention is the holder 52, which combines the blowing nozzles 18 in their front region and in turn connects them to the sley 26. On the base 38 of this holder 52, two pneumatic cylinders 34a and 34b are arranged one behind the other and below the blowpipes 18. They are in contact with two clamps 37 which surround the blow nozzles 18 and which bundle the tubes in bundles. A compression spring 35 is arranged above the clamps 37, which cooperate as a counterforce with the pneumatic cylinders 34a and 34b, since they are clamped between the clamps 37 and the holder 52. The number and arrangement of the pneumatic cylinders 34 and the compression spring 35 is not critical, but can be chosen within a suitable framework, as long as it is ensured that a correct and precise pivoting of the tubular blowing nozzles 18 is ensured, so that the respective shot lengths 32 are obtained from the desired ones Blow nozzles 18 can enter the U-shaped channel 14 of the reed 16. This is shown more clearly in cross section at the bottom left in FIG. 1, where the Openings 1 and 2 of the uppermost blow nozzles 18 are in the entry position for the U-shaped channel 14 of the reed 16, while the middle openings 3 and 4 and the lower openings 5 and 6 of the blow nozzles 18 lie below the entry position and are therefore in the rest position. Only by vertically swiveling the blowing nozzles 18 via the pivot point 36 by means of the pneumatic cylinders 34a and b can the middle or lower blowing nozzles 18 with their openings 3 and 4 or 5 and 6 be brought into the desired firing position. The control for the pneumatic cylinders is not shown because it is obvious to a person skilled in the art.

Zusammenfassend läßt sich also feststellen, daß die erfindungsgemäße Schußeintragungsvorrichtung für Webmaschinen in der gezeigten Grundstellung Farbe und/ oder Qualität aus den Öffnungen 1 und/oder 2 der Blasdüsen eintragen kann. Bei Betätigung des pneumatischen Zylinders 34a werden die Öffnungen 3 und/oder 4 der Blasdüsen 18 in Schußposition gebracht, während die Betätigung des pneumatischen Zylinders 34b dafür sorgt, daß die Öffnungen 5 und 6 der Blasdüsen 18 in die gewünschte Schußposition gebracht werden. Es versteht sich, daß dieses System auf weitere Farben und/oder Qualitäten erweitert werden kann. Auch ist es denkbar, daß nur ein pneumatischer Zylinder 34 eingesetzt wird, dessen Hub in unterschiedlicher Weise gesteuert wird.In summary, it can be stated that the weft insertion device according to the invention for weaving machines in the basic position shown can insert color and / or quality from openings 1 and / or 2 of the blowing nozzles. When the pneumatic cylinder 34a is actuated, the openings 3 and / or 4 of the blow nozzles 18 are brought into the firing position, while the actuation of the pneumatic cylinder 34b ensures that the openings 5 and 6 of the blow nozzles 18 are brought into the desired firing position. It is understood that this system can be expanded to other colors and / or qualities. It is also conceivable that only one pneumatic cylinder 34 is used, the stroke of which is controlled in different ways.
