Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Schneiden von Schussfäden gemäss dem Oberbegriff des Anspruches 1 sowie eine Webmaschine mit einer derartigen Schneidvorrichtung.The present invention relates to a device for cutting weft threads according to the preamble of claim 1 and a weaving machine with such a cutting device.
Aus der JP-A 64-33246 ist eine Schneidvorrichtung bekannt, die ein lagestabil und ein verschiebbar angeordnetes Schneidorgan aufweist. Die Schneidorgane sind um parallel angeordnete Drehachsen gegenläufig drehbar und zur Bildung einer Schneidstelle abschnittweise aneinander liegend angeordnet. Das verschiebbare Schneidorgan ist an einem Koppelglied befestigt, das axial verschiebbar auf einer Antriebswelle der Vorrichtung angeordnet ist. In dem Koppelglied ist eine Schraubenfeder angeordnet, die das verschiebbare Schneidorgan gegen das lagestabile Schneidorgan drückt, so dass eine kraftschlüssige Verbindung geschaffen wird, durch welche das lagestabile Schneidorgan angetrieben wird.From JP-A 64-33246 a cutting device is known which has a positionally stable and a displaceably arranged cutting member. The cutting members can be rotated in opposite directions about parallel axes of rotation and are arranged in sections to form a cutting point. The displaceable cutting member is fastened to a coupling member which is arranged axially displaceably on a drive shaft of the device. A helical spring is arranged in the coupling member, which presses the displaceable cutting element against the positionally stable cutting element, so that a force-locking connection is created, by means of which the positionally stable cutting element is driven.
Bei dieser Schneidvorrichtung erweist es sich als nachteilig, dass das Koppelglied die Drehung übertragen, die kraftschlüssige Verbindung der Schneidorgane herstellen und gleichzeitig den seitlichen Axialschlag des rotierenden lagestabilen Schneidorgans kompensieren muss. Diese Mehrfachfunktion des Koppelgliedes führt zu Beschränkungen in der Drehzahl der Schneidorgane und einer durch Schlupf verursachten starken Abnutzung der Schneiden und folglich kürzeren Standzeiten der Schneidorgane.In this cutting device, it proves to be disadvantageous that the coupling member transmit the rotation, produce the non-positive connection of the cutting members and at the same time the lateral axial stroke of the rotating positionally stable cutting member must compensate. This multiple function of the coupling member leads to restrictions in the speed of the cutting elements and a severe wear of the cutting edges caused by slippage and consequently shorter service life of the cutting elements.
Der Erfindung liegt die Aufgabe zugrunde, eine Schneidvorrichtung zu schaffen, bei der durch Aufteilung der Funktionen, Antrieb der Schneidorgane und kraftschlüssige Verbindung der Schneidorgane, die genannten Nachteile zu beheben. Darüberhinaus weist die vorliegende Lösung der Rotationsbewegung den Vorteil auf, dass bei hoher Schneidkadenz eine einwandfreie Funktion gewährleistet ist.The invention has for its object to provide a cutting device in which, by dividing the functions, driving the cutting members and non-positive connection of the cutting members, the disadvantages mentioned. In addition, the present solution of the rotational movement has the advantage that a perfect function is guaranteed with a high cutting rate.
Diese Aufgabe wird erfindungsgemäss mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved according to the invention with the characterizing features of claim 1.
Die mit der Erfindung erzielbaren Vorteile sind im wesentlichen darin zu sehen, dass aufgrund der massenarmen Ausführung und der freidrehbaren Anordnung des beweglichen Schneidorgans eine einwandfreie kraftschlüssige Verbindung gewährleistet und in axialer Richtung auftretende Axialschläge durch die Halteteile reibungslos kompensiert werden.The advantages that can be achieved with the invention are essentially to be seen in the fact that, due to the low-mass design and the freely rotatable arrangement of the movable cutting member, a perfect non-positive connection is guaranteed and axial shocks occurring in the axial direction are smoothly compensated by the holding parts.

Die Schussfadenschneidvorrichtung hat zwei Schneidorgane 1, 2, die um zwei parallel verlaufende Drehachsen 3, 4, drehbar sind, wobei das eine Schneidorgan lagestabil angeordnet ist und nachfolgend als Hauptschneide 1 bezeichnet wird, und das andere Schneidorgan 2 beweglich angeordnet ist und nachfolgend als Aussenschneide 2 bezeichnet wird. Die Hauptschneide 1 und die Aussenschneide 2 sind zur Bildung einer Schneidstelle teilweise überlappend angeordnet. Die Hauptschneide 1 ist an einen rotierenden Teil (nicht dargestellt) befestigt, welcher die Hauptschneide antreibt. Die Aussenschneide 2 ist um die Drehachse 4 drehbar angeordnet und wird gegen die Hauptschneide 1 gedrückt, so dass die Aussenschneide 2 in der entgegengesetzten Richtung dreht. Die Aussenschneide 2 ist z.B. um 1,5° geschränkt zur Hauptschneide, um eine Punktberührung zwischen den Schneiden zu erreichen.The weft thread cutting device has two
Hierzu ist die Aussenschneide 2 mittels Walzkörperlager 5 auf einer Achse 6 gelagert, die axial verschiebbar aber verdrehfest in einem Gehäuse 7 angeordnet ist. Auf der Achse 6 ist eine Schraubenfeder 8 angeordnet, die einerseits an einer Schulter 9 im Gehäuse 7 und andererseits an einer Wulst 10 an der Achse 6 anliegt. Diese Schraubenfeder 8 ist eine Druckfeder, welche die Aussenschneide 2 gegen die Hauptschneide 1 zieht, so dass eine kraftschlüssige Verbindung zwischen der Haupt- und Aussenschneide 1, 2 erzeugt wird. Durch diese kraftschlüssige Verbindung wird die Aussenschneide 2 durch die Hauptschneide 1 angetrieben. Die Achse 6 ist in zwei ebenen Membranfedern 11 gelagert, die zueinander beabstandet im Gehäuse 7 angeordnet und durch zwei Deckel 12, 13 im Gehäuse 7 befestigt sind, so dass die Membranfedern 11 quer zur Drehachse 4 der Achse 6 angeordnet sind. Das Gehäuse 7 ist zylinderförmig ausgebildet und weist ein Aussengewinde 14 auf. Das Gehäuse 7 ist in einen Halter 15 einschraubbar, um die Aussenschneide 2 bezüglich der Hauptschneide 1 zu verstellen.For this purpose, the
Die Hauptschneide 1 ist ringförmig ausgebildet und weist zwei durch Bruch erzeugte Trennstellen 17 auf, um die Hauptschneide 1 zur Montage in zwei Teile zu trennen (Fig.2).

Wie die Fig. 3 zeigt, ist in Fadenlaufrichtung gesehen auf der Eintragseite der Webmaschine vor der Schussfadenhaltevorrichtung und auf der Fangseite der Webmaschine nach der Schussfadenhaltevorrichtung jeweils eine vorstehend beschriebene Schussfadenschneidvorrichtung angeordnet.3 has a
Die Fig. 4 zeigt die Anordnung der Schneidvorrichtung 25 bezüglich der Verteilvorrichtung 23, die einen stillstehenden Teil und einen mit dem Webrotor 22 rotierenden Teil 32 aufweist. Die Hauptschneide 1 ist an dem Teil 32 befestigt und dreht synchron mit dem Webrotor. Die Aussenschneide 2 überlappt die Hauptschneide 1, um die Schneidestelle zu bilden. Die Anordnung ist so ausgelegt, dass die Aussenschneide 2 in einem geeigneten Abstand von der Haltevorrichtung liegt, um das Schneiden des Schussfadens zu gewährleisten.Fig. 4 shows the arrangement of the
Für ein einwandfreies Schneiden des Schussfadens ist ferner die aus der schematischen Darstellung nach Fig. 5 ersichtliche Zuordnung der Schneidvorrichtung und der Haltevorrichtung wesentlich.For a perfect cutting of the weft thread, the assignment of the cutting device and the holding device, which can be seen from the schematic illustration according to FIG.
Die Haltevorrichtung enthält zwei endlose Transportbänder 41, 42. Ein Transportband 41 ist um eine Umlenkrolle 43 und um den Webrotor 21 gelegt, der das Transportband 41, nachfolgend als treibendes Band bezeichnet, antreibt. Das Transportband 41 ist ferner über einen Führungsteil 44 geführt, der mit einer Einrichtung (nicht dargestellt) versehen ist, um zwischen der Lauffläche am Führungsteil 44 und der Oberfläche des Transportbandes eine Luftschmierung zu bewirken. Das andere Transportband 42 ist um zwei Umlenkrollen 45 so geführt, dass auf der Oberfläche des treibenden Bandes 41 jeweils ein Oberflächenabschnitt des Transportbandes 42 aufliegt. Dadurch wird dieses Transportband 42 vom treibenden Band 41 angetrieben und nachfolgend als getriebenes Band 42 bezeichnet. In der Fig. 5 sind ausserdem die Hauptschneide 1 und die Aussenschneide 2 sowie die Laufbahn 46 der Schusseintragdüsen 47 dargestellt, welche synchron mit dem Webrotor 22 drehen (Pfeil A). Wie bereits erwähnt, sind die Hauptschneide 1 und die Aussenschneide 2 überlappend angeordnet, wodurch die Schneidstelle gebildet wird. Wie die Darstellung zeigt, bilden das treibende und getriebene Band 41, 42 einen Einlaufspalt, in welchen der Schussfaden nach Beendigung des Eintrages geklemmt wird. Es wird eine Klemmstelle 49 gebildet, die durch die Zuordnung der Schneid- und Kaltevorrichtung in der Laufrichtung des Schussfadens vor der Schneidstelle 48 liegt. Damit wird gewährleistet, dass der Schussfaden vor dem Schneiden in der Haltevorrichtung gehalten und anschliessend an der Schneidstelle vorbei bis zu einem Anschlagpunkt weiterbefördert wirdThe holding device contains two
