Description

Die Erfindung betrifft eine Projektilwebmaschine mit einem die Energie für den Projektilabschuss liefernden, vor jedem Schuss in Torsion versetzten Torsionsstab, der in einer an der Maschine angebrachten Halterung gehalten ist.The invention relates to a projectile weaving machine with a torsion bar which supplies the energy for the projectile launch and is set in torsion before each shot and which is held in a holder attached to the machine.

Eine solche Projektilwebmaschine ist z. B. in der CH-PS 382 682 offenbart. Dabei hat die Halterung des Torsionsstabes ein separates Gehäuse mit ÖI-oder Fettfüllung zwecks Schmierung. Dieser Stand der Technik hat jedoch den Nachteil, dass der Torsionsstab einer unterschiedlichen Erwärmung unterliegt. Auf der Einspannstelle werden z.B. 20-25°C, an der Beschleunigerseite hingegen 80-90°C gemessen. Diese extremen Temperaturunterschiede können zu Korrosionsbildung am nicht geschmierten Mittelteil des Torsionsstabes führen.Such a projectile weaving machine is e.g. B. disclosed in CH-PS 382 682. The holder of the torsion bar has a separate housing with oil or grease filling for lubrication. However, this prior art has the disadvantage that the torsion bar is subject to different heating. At the clamping point, e.g. 20-25 ° C, however measured 80-90 ° C on the accelerator side. These extreme temperature differences can lead to the formation of corrosion on the non-lubricated middle part of the torsion bar.

Aufgabe der Erfindung ist es, die eingangs genannte Projektilwebmaschine so zu verbessern, dass Korrosionsbildung und Bruch in bezug auf den Torsionsstab mit Sicherheit vermieden werden.The object of the invention is to improve the projectile weaving machine mentioned at the outset in such a way that corrosion and breakage with respect to the torsion bar are avoided with certainty.

Zur Lösung dieser Aufgabe dient die Massnahme, dass der Torsionsstab wenigstens in einem Endberecht mit Öl beaufschlagbart ist.To solve this problem, the measure is that the torsion bar is loaded with oil at least in one final authorization.

Hierdurch lässt sich eine gleichmässige Kühlung und Schmierung des genannten Torsionsstabes erreichen, so dass die bisherigen extremen Temperaturunterschiede sowie die Korrosion eliminiert werden, wodurch eine wesentliche Erhöhung der Lebensdauer des Torsionsstabes gewährleistet ist.In this way, uniform cooling and lubrication of the torsion bar mentioned can be achieved, so that the previous extreme temperature differences and corrosion are eliminated, which ensures a substantial increase in the life of the torsion bar.

Nach einer besonders vorteilhaften Ausführung der Erfindung kann die Halterung einen Öleintritt aufweisen und mit einem Gehäusestück verbunden sein, wobei zwischen der Halterung und dem Gehäusestück wenigstens eine Öldurchtrittsöffnung vorgesehen ist, derart, dass im Ringraum zwischen dem Gehäusestück und dem Torsionsstab eine Ölströmung gewählreistet ist, wobei ferner zwischen dem Olaustritt und dem Ringraum und der Halterung ein Ölkreislauf vorgesehen sein kann. Hierdurch ist eine kontinuierliche Schmierung und/oder Kühlung des Torsionsstabes gewährleistet.According to a particularly advantageous embodiment of the invention, the holder can have an oil inlet and be connected to a housing piece, at least one oil passage opening being provided between the holder and the housing piece, such that an oil flow is selected in the annular space between the housing piece and the torsion bar, wherein an oil circuit can also be provided between the oil outlet and the annular space and the holder. This ensures continuous lubrication and / or cooling of the torsion bar.

Der Ölkreislauf kann dabei eine hydraulische Bremsvorrichtung umfassen. Hierdurch wird der Vorteil erreicht, dass das bereits vorhandene Bremsöl auch für die Schmierung und Kühlung des Torsionsstabes eingesetzt werden kann.The oil circuit can include a hydraulic braking device. This has the advantage that the existing brake oil can also be used for the lubrication and cooling of the torsion bar.

Der Ölkreislauf kann einen Ölkühler umfassen. Hierdurch lässt sich eine optimale Temperatur des Öls am Torsionsstab einstellen.The oil circuit can include an oil cooler. This allows an optimal temperature of the oil to be set on the torsion bar.

Das Gehäusestück kann eine den Torsionsstab umgebende, einen Öldurchtritt gewährleistete Verlängerungsmanschette aufweisen. Dies hat den Vorteil einer besonders günstigen Ringraumströmung um den Torsionsstab mit optimalem Kühleffekt.The housing piece can have an extension sleeve which surrounds the torsion bar and ensures oil passage. This has the advantage of a particularly favorable annulus flow around the torsion bar with an optimal cooling effect.

Der Ölkreislauf kann auch eine von der Hauptwelle angetriebene Umwälzpumpe umfassen. Hierdurch ist ein besonders wirkungsvoller Wärmeübergang der Kühlung gewährleistet.The oil circuit can also include a circulation pump driven by the main shaft. This ensures a particularly effective heat transfer of the cooling.

Schliesslich kann der Olkühler als hohlprofilartiger Träger ausgeführt sein. dies ermöglicht eine besonders platzsparende Anordnung der Ölkühlung.Finally, the oil cooler can be designed as a hollow profile-like carrier. this enables a particularly space-saving arrangement of the oil cooling.

Bei der Projektilwebmaschine nach Fig. 1 ist ein Torsionsstab 1 mit einem verzahnten Kopf 2 in einer Halterung 19 mit einer Platte 21 drehfest gehalten, die mittels durch Langlöcher 22, 23 geführter Schrauben 24, 25 an einem Flansch 26 eines rohrartigen Gehäusestückes 27 einstellbar befestigt ist. Das Rohrstück 27 besitzt am anderen Ende einen Flansch 28, mit dem es an dem Gehäuse 50 angeschraubt ist, sowie eine Verlängerungsmanschette 51. Mit einer in der Halterung 19 befindlichen Öleintrittsöffnung 29 ist eine Olleitung 31 verbunden.In the projectile weaving machine according to FIG. 1, a torsion bar 1 with a toothed head 2 is held in a rotationally fixed manner in a holder 19 with a plate 21, which is adjustably fastened to a flange 26 of a tubular housing piece 27 by means of screws 24, 25 guided through elongated holes 22, 23 . The pipe section 27 has at the other end a flange 28, with which it is screwed to the housing 50, and an extension sleeve 51. An oil line 31 is connected to an oil inlet opening 29 in the holder 19.

Am anderen Ende trägt der Torsionsstab 1 einen gemäss Pfeil 40 beweglichen Schlaghebel 3, an den ein Schlagstück 4 angelenkt ist, von dem aus ein Projektil 5 in Richtung des Pfeils 45 durch die Projektilführung 33 beschleunigt werden kann. Die Projektilführung besteht aus einer Vielzahl von Zähnen, die auf der Lade 34 angeordnet sind, und zwar vor dem Riet 35. Lade 34, Riet 35 und Projektilführung 33 führen während des Werbebetriebs eine Hin- und Herverschwenkbewegung gemäss Pfeil 36 aus, wodurch der in das Fach eingetragene Schussfaden an das Gewebe angeschlagen wird. Das Projektil 5 wird von einem gemäss Pfeil 41 hin- und herverschwenkbaren Schützenhebel 37 in die gezeichnete Stellung gehoben, in welcher seine den Faden ergreifende Klammer durch einen Projektilöffner 6 geöffnet wird, der sich gemäss dem Pfeil 38 hin- und herverschwenken lässt.At the other end, the torsion bar 1 carries a striking lever 3 which is movable according to arrow 40, to which a striking piece 4 is articulated, from which a projectile 5 can be accelerated in the direction of arrow 45 through the projectile guide 33. The projectile guide consists of a plurality of teeth, which are arranged on the drawer 34, namely in front of the reed 35. The drawer 34, reed 35 and projectile guide 33 perform a back and forth swiveling movement according to arrow 36 during the advertising operation, as a result of which the into the Tray inserted weft thread is struck on the fabric. The projectile 5 is lifted into the position shown by a shooter lever 37 which can be pivoted back and forth according to arrow 41, in which its clamp gripping the thread is opened by a projectile opener 6 which can be pivoted back and forth according to arrow 38.

Mit dem Torsionsstab 1 ist ein Arm 11 drehfest verbunden, der über einen Lenker 20 mit einem am Bolzen 10 verschwenkbar gelagerten, aus zwei Scheiben bestehenden Hebel 9 durch das Gelenk 30 gelenkig verbunden ist. Die Teile 9, 20 bilden einen Kniehebel, das Gelenk 30 ein Kniegelenk. Der Hebel 9 trägt eine Rolle 17, die mit einer Nockenscheibe 12 zusammenarbeitet, welche auf einer Weil 8 sitzt. Die Nockenscheibe 12 trägt eine Rolle 14, die mit einer an dem Hebel 9 gebildeten Kurve 13 zusammenwirkt. Der Hebel 9 ist überdies mit dem Kolben 16 einer als Ganzes mit 15 bezeichneten hydraulischen Bremseinrichtung gelenkig verbunden. Diese wirkt erst, wenn der vordere Bremskolben 32 in den ihm angepassten Bremsraum 39 geschoben wird, also wenn der Schlaghebel 3 einen gewissen Winkel durchlaufen hat. Die Welle 8 trägt ein Kegelrad 42, das in ein weiteres Kegelrad 43 eingreift, welches auf der Hauptwelle 7 der Webmaschine angebracht ist. Welle 8 und Nockenscheibe 12 werden kontinuierlich von der Hauptwelle 7 aus angetrieben. Das Gehäuse 50 weist einen Ölaustritt 52 mit einem Ölstandsanzeiger 54 und einer angeschlossenen Ölleitung 56 auf.With the torsion bar 1, an arm 11 is rotatably connected, which is articulated via a link 20 to a pivotable on the pin 10, consisting of two disks lever 9 by the joint 30. The parts 9, 20 form a toggle lever, the joint 30 a knee joint. The lever 9 carries a roller 17 which cooperates with a cam disc 12, which sits on a Weil 8. The cam disk 12 carries a roller 14 which interacts with a curve 13 formed on the lever 9. The lever 9 is also articulated to the piston 16 of a hydraulic brake device designated as a whole by 15. This only takes effect when the front brake piston 32 is pushed into the brake chamber 39 that is adapted to it, that is, when the striking lever 3 passes through a certain angle Has. The shaft 8 carries a bevel gear 42 which engages in another bevel gear 43 which is attached to the main shaft 7 of the weaving machine. Shaft 8 and cam disk 12 are continuously driven from the main shaft 7. The housing 50 has an oil outlet 52 with an oil level indicator 54 and a connected oil line 56.

Gemäss Fig. 2 ist der Torsionsstab 1 unter Zwischenlage einer einen als Öldurchtrittsöffnung dienenden axialen Kanal 46 aufweisende Büchse 47 drehbar in dem Flansch 26 und in der darauf aufgeschraubten Platte 21 gelagert. Der Kopf 2 besitzt überdies eine Verzahnung 48, während die Halterung 19 eine Verzahnung 49 aufweist. Bei beiden Verzahnungen sind in benannter Art und Weise die Zahnlücken zwischen je zwei aufeinanderfolgenden Zähnen doppelt so gross, als die Dicke eines Zahnes beträgt. Die Verzahnungen 48, 49 können dadurch hergestellt werden, dass aus einer vollen Kreisverzahnung jeweils der übernächste Zahn herausgeschnitten wird.2, the torsion bar 1 is rotatably supported in the flange 26 and in the plate 21 screwed thereon, with the interposition of a bushing 47 having an axial channel 46 serving as an oil passage opening. The head 2 also has a toothing 48, while the holder 19 has a toothing 49. In the case of both toothings, the tooth gaps between two successive teeth are twice as large as the thickness of one tooth. The toothings 48, 49 can be produced by cutting out the tooth after next from a full circular toothing.

Gemäss Fig. 3 ist die Ölleitung 56 mit einem Ölkühler 58 verbunden, welcher zwei durch eine Trennwand 60 getrennte Kammern 62, 64 aufweist und über die Ölleitung 66 mit einer von der Hauptwelle 7 angetriebenen Umwälzpumpe 68 verbunden ist. Der Ölkühler 58 ist im Träger 70 untergebracht, welcher an der Maschinenwange 72 befestigt ist. An dieser ist auch die Spule 74 für den Schussfaden 76 angebracht. Das aus diesem zusammen mit den Kettfäden 77 gebildete fertige Gewebe ist mit 78 bezeichnet.3, the oil line 56 is connected to an oil cooler 58 which has two chambers 62, 64 separated by a partition 60 and is connected via the oil line 66 to a circulation pump 68 driven by the main shaft 7. The oil cooler 58 is accommodated in the carrier 70, which is fastened to the machine cheek 72. The bobbin 74 for the weft thread 76 is also attached to this. The finished fabric formed from this together with the warp threads 77 is designated 78.

Die Wirkungsweise ist folgende. Wenn die Erhebung 18 der Nockenscheibe 12 auf die Rolle 17 aufläuft, gelangen die Teile in die gezeichnete Stellung, nämlich die Streckstellung des Kniegelenks 30, in der der Torsionsstab 1 über den Arm 11 relativ zu der festen Einspannstelle bei 2 tordiert ist. Sobald anschliessend die Rolle 14 der Nockenscheibe 12 auf die Kurve 13 aufläuft, geht der Kniehebel 9, 20 aus der gezeichneten Strecklage gemäss Pfeil 44 heraus und das Kniegelenk 30 wird geknickt, so dass sich der Torsionsstab 1 entspannen kann und der Schlaghebel 3 in Fig. 1 nach rechts verschwenkt wird. Dabei wird der Schützen 5 durch die Schützenführung 33 und damit durch das Webfach geschossen. Der Schussfaden 76 wird eingetragen. Wenn der Torsionsstab 1 in normaler Stärke tordiert wird, ist auch der beider Entspannung zurückgelegte, bis zur torsionslosen Stellung zu messende Drehwinkel so gross, dass die Bremsvorrichtung 15 noch während des Zurückdrehens des Torsionsstabes 1 wirksam wird.The mode of action is as follows. When the elevation 18 of the cam disc 12 runs onto the roller 17, the parts reach the position shown, namely the extended position of the knee joint 30, in which the torsion bar 1 is twisted at 2 over the arm 11 relative to the fixed clamping point. As soon as the roller 14 of the cam disk 12 then runs onto the curve 13, the toggle lever 9, 20 goes out of the drawn position according to arrow 44 and the knee joint 30 is bent, so that the torsion bar 1 can relax and the hammer lever 3 in Fig. 1 is pivoted to the right. The shooter 5 is shot through the shooter guide 33 and thus through the shed. The weft thread 76 is inserted. If the torsion bar 1 is twisted in normal strength, the angle of rotation covered during relaxation, which is to be measured up to the torsion-free position, is also so great that the braking device 15 becomes effective while the torsion bar 1 is being turned back.

Das im Gehäuse 50 vorhandene Bremsöl wird durch den Ölaustritt 52 und die Leitung 56, über den Ölkühler 58, die Ölleitung 66, die Umwälzpumpe 68 und die Ölleitung 31 zur Öleintrittsöffnung 29 der Halterung 19 geführt. Hier strömt es gemäss den Pfeilen 80, 82, 84 (Fig. 2) durch die Verzahnung 48, 49, gemäss Pfeil 86 durch den als Öldurchtrittsöffnung dienenden Kanal 46 in den Ringraum 88 zwischen dem Torsionsstab 1 und dem Rohrstück 27 bzw. der Verlängerungsmanschette 51 (Pfeile 90, 92) und strömt schliesslich gemäss Pfeil 94 beim Ölaustritt 55 (Fig. 1) wieder zurück in das Gehäuse 50. Dabei wird der Torsionsstab 1 im wesentlichen in seiner ganzen Länge gleichmässig gekühlt bzw. geschmiert.The brake oil present in the housing 50 is passed through the oil outlet 52 and the line 56, via the oil cooler 58, the oil line 66, the circulating pump 68 and the oil line 31 to the oil inlet opening 29 of the holder 19. Here it flows according to the arrows 80, 82, 84 (FIG. 2) through the teeth 48, 49, according to arrow 86 through the channel 46 serving as an oil passage opening into the annular space 88 between the torsion bar 1 and the pipe section 27 or the extension sleeve 51 (Arrows 90, 92) and finally flows according to arrow 94 at the oil outlet 55 (FIG. 1) back into the housing 50. The torsion bar 1 is cooled or lubricated essentially over its entire length.

Bei der Variante nach Fig. 4 ist der Ölkühler 96 als hohlprofilartiger Träger ausgeführt, welcher direkt zwischen den Maschinenwangen 72,73 befestigt ist und somit gleichzeitig mit seiner Kühlfunktion eine tragende Funktion ausübt. Hierdurch ist eine besonders platzsparende Bauweise gewährleistet.In the variant according to FIG. 4, the oil cooler 96 is designed as a hollow profile-like carrier which is fastened directly between the machine cheeks 72, 73 and thus simultaneously performs a load-bearing function with its cooling function. This ensures a particularly space-saving design.

Es versteht sich, dass der Öleintritt, wie in Fig. 2 gestrichelt mit 98 angedeutet ist, auch direkt in den Ringraum 88 vorgesehen sein kann, wodurch der Torsionsstab wenigstens im Bereich einer Halterung mit Öl beaufschlagbar ist.It goes without saying that the oil inlet, as indicated by broken lines in FIG. 2 at 98, can also be provided directly in the annular space 88, as a result of which the torsion bar can be acted upon with oil at least in the region of a holder.
