Description

Die Erfindung betrifft eine Kettablass-Steuereinrichtung für Webmaschinen mit mindestens zwei Teilkettbäumen, mit einem in Kettlaufrichtung den Kettbäumen nachgeschalteten ortsfesten stangenförmigen Umlenkelement für die Kette und einem diesem nachgeschalteten unter Federwirkung beweglichen Spannbaum. Bei einer in der schweizerischen Patentschrift Nr. 509 219 beschriebenen ähnlichen Steuereinrichtung wird die Kettablassgeschwindigkeit, also die Drehzahl des Kettbaumes, dadurch gesteuert, dass der Spannbaum beispielsweise bei zu geringer Drehzahl des Kettbaumes gegen den Uhrzeigersinn nach unten gedrückt wird und so über einen Hebelarm die Kettbaumbremse entlastet, so dass der Kettbaum unter der erhöhten Kettspannung schneller laufen kann. Damit die Kettspannung während des Abwebens des ganzen Kettbaumes möglichst konstant bleibt, ist eine Tastrolle zwischen Umlenkbaum und Kettbaum angebracht, die von den Kettfäden beaufschlagt wird und mit abnehmendem Kettbaumdurchmesser ihre Lage verändert, da die mit ihr in Berührung stehende Kettschar dem Umfang des Kettbaums folgt. Die Tastrolle ist über ein Gestänge mit dem erwähnten Hebel verbunden und wirkt mit abnehmendem Kettbaumdurchmesser auf die Kettbaumbremse in ähnlicher Weise wie der Spannbaum bei zunehmender Kettspannung entlastend.The invention relates to a warp let-off control device for weaving machines with at least two partial warp beams, with a stationary rod-shaped deflecting element for the chain, which is connected downstream of the warp beams in the warp running direction, and a tensioning boom, which is connected downstream and movable under spring action. In a similar control device described in Swiss Patent Specification No. 509 219, the warp let-off speed, i.e. the speed of the warp beam, is controlled by pressing the tensioning arm downwards counterclockwise, for example when the speed of the warp beam is too low, and thus the warp beam brake via a lever arm relieved, so that the warp beam can run faster under the increased warp tension. To ensure that the warp tension remains as constant as possible while weaving the entire warp beam, a feeler roller is attached between the deflection beam and the warp beam, which is acted upon by the warp threads and changes its position as the warp beam diameter decreases, since the warp sheet in contact with it follows the circumference of the warp beam. The feeler roller is connected to the above-mentioned lever via a linkage and, with a decreasing warp beam diameter, acts on the warp beam brake in a similar way to the tensioning beam with increasing warp tension.

Die Erfahrung mit mehreren Teilkettbäumen in einer Webmaschine hat gezeigt, dass die Kettablassgeschwindigkeit jedes Teilkettbaumes individuell geregelt werden muss, da sich beim Bewickeln von Kettbäumen immer Unterschiede in Spannung und Dicke der Kettfäden ergeben und diese Unterschiede beim Abweben ohne individuelle Steuerung in den Gewebebahnen sichtbar würden, was von den Abnehmern solcher Gewebe nicht toleriert wird. Bei einer Webmaschine mit mehreren Teilkettbäumen müsste demnach die Kettablasssteuereinrichtung gemäss der CH-PS 509 219 für jeden einzelnen Teilkettbaum separat ausgeführt werden, wodurch die Herstellungskosten einer solchen Webmaschine ungünstig beeinflusst würden.Experience with several sub-warp beams in a weaving machine has shown that the warp let-off speed of each sub-warp beam must be regulated individually, since there are always differences in tension and thickness of the warp threads when winding warp beams and these differences would be visible in weaving without individual control in the fabric webs, which is not tolerated by the buyers of such fabrics. In the case of a weaving machine with several warp beams, the warp let-off control device according to CH-PS 509 219 would therefore have to be carried out separately for each individual warp beam, as a result of which the manufacturing costs of such a weaving machine would be adversely affected.

Der Erfindung liegt die Aufgabe zugrunde, eine Kettablass-Steuereinrichtung zu schaffen, die auch beim Abweben von mehreren Teilkettbäumen einen einzigen durchgehenden Spannbaum erlaubt und bei der diejenigen Elemente, welche für jeden einzelnen Teilkettbaum mehrfach angeordnet werden müssen, möglichst einfach gestaltet sind. Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass zur individuellen Einstellung der Kettablassgeschwindigkeit einer Teilkette abhängig von der Fadenspannung in dieser Teilkette einem Teilkettbaum ein zwischen Umlenkelement und Spannbaum angeordnetes Tastorgan einer Steuereinrichtung zugeordnet ist, durch das die Spannung der jeweiligen Teilkette abgetastet wird.The invention has for its object to provide a warp let-off control device which allows a single continuous spanning beam even when weaving several sub-warp beams and in which those elements which have to be arranged several times for each individual warp beam are designed as simply as possible. This object is achieved according to the invention in that for the individual adjustment of the warp let-off speed of a part chain, depending on the thread tension in this part chain, a part warp beam is assigned to a control element arranged between the deflection element and the tensioning tree, by means of which the tension of the respective part chain is sensed.

Durch die erfindungsgemässe Einrichtung werden Spannungsunterschiede in den einzelnen Teilketten, die von Teilkettbäumen ablaufen, auch bei Verwendung eines einzigen Spannbaumes rasch ausgeglichen, da die einzelnen Tastrollen die unterschiedlichen Spannungen in den Teilketten trägheitslos registrieren können und über die jeweils zugeordnete Steuereinrichtung für eine rasche Korrektur der Kettablassgeschwindigkeit des einzelnen Teilkettbaumes sorgen.By means of the device according to the invention, tension differences in the individual partial chains which run from partial warp beams are quickly compensated for even when using a single tensioning tree, since the individual sensing rollers can register the different tensions in the partial chains without inertia and via the respectively assigned control device for a rapid correction of the warp let-off speed of the individual part warp beam.

Im folgenden wird die Erfindung anhand der Figuren näher beschrieben.The invention is described in more detail below with reference to the figures.

Es zeigen :

  • Figur 1 eine schematische Darstellung einer erfindungsgemäss ausgebildeten Webmaschine, von der Kettseite her gesehen,
  • Figur 2 einen Schnitt nach Linie 11-11 in Fig. 1, in grösserem Massstab.
Show it :
  • FIG. 1 shows a schematic representation of a weaving machine designed according to the invention, seen from the warp side,
  • Figure 2 shows a section along line 11-11 in Fig. 1, on a larger scale.

Zwischen den beiden Maschinenwangen 1, 2 sind zwei Teilkettbäume 3, 4 angeordnet, welche Teilwebbreiten A, B besitzen. Der Teilkettbaum 3 ist von einem Elektromotor 5, der Teilkettbaum 4 von einem Elektromotor 6 jeweils über einen Zahnradtrieb 7 angetrieben. Vom Teilkettbaum 3 läuft die Webkette 8 (8a = Position bei leerem Kettbaum), vom Teilkettbaum 4 die Webkette 9 gemäss den Pfeilen 11 bzw. 11 a ab. Die Gesamtwebbreite der Maschine ist mit C bezeichnet. Innen sind die beiden Kettbäume 3, 4 durch eine Zwischenstütze 12 abgestützt.Two partial warp beams 3, 4, which have partial weaving widths A, B, are arranged between the two machine cheeks 1, 2. The partial warp beam 3 is driven by an electric motor 5, the partial warp beam 4 by an electric motor 6 each via a gear drive 7. The weaving chain 8 runs from the partial warp beam 3 (8a = position when the warp beam is empty), and the weaving chain 9 runs from the partial warp beam 4 in accordance with the arrows 11 and 11 a. The overall weaving width of the machine is labeled C. The two warp beams 3, 4 are supported on the inside by an intermediate support 12.

Die Webketten 8, 9 sind über eine ortsfest im Maschinengestell angeordnete, den Kettbäumen 3, 4 - in Kettlaufrichtung 11 - nachgeschaltete, drehfeste Umlenkwalze 13 und einen dieser nachgeschalteten Spannbaum 14 geführt, worauf sie durch die weiteren Teile der Webmaschine wie Schäfte, Riet usw. geleitet werden. Die Teile 13, 14 erstrecken sich über die gesamte Breite C der Webmaschine.The weaving chains 8, 9 are guided over a fixed, arranged in the machine frame, the warp beams 3, 4 - in the warp running direction 11 - downstream, non-rotatable deflection roller 13 and a spreader beam 14 connected thereafter, whereupon they pass through the other parts of the weaving machine such as heald frames, reeds, etc. be directed. The parts 13, 14 extend over the entire width C of the weaving machine.

Aus der Kette 8 sind eine Anzahl, z. B. hundert Kettfäden 15 über eine Tastrolle 16 geführt. Entsprechend sind eine Anzahl Kettfäden 17 der Kette 9 über eine Tastrolle 18 geleitet. Jede Rolle 16, 18 ist auf einer Blattfeder 20 befestigt, die bei 19 in einem Schuh 21 angebracht ist. Der Schuh 21 ist mittels einer Verschraubung 22 auf der Umlenkwalze 13 befestigt. Der Schuh 21 trägt überdies einen Sensor 23, der über eine elektrische Leitung 24 mit einer dem Teilkettbaum 3 zugeordneten Teilsteuereinrichtung 25 verbunden ist. In ganz entsprechender Weise ist die Tastrolle 18 auf der Umlenkwalze 13 befestigt und es ist eine Steuerleitung 26 zu einer dem Teilkettbaum 4 zugeordneten Teil-Steuereinrichtung 27 geführt. Von der Steuereinrichtungen 25, 27 sind die Antriebsmotoren 5, 6 der beiden Kettbäume 3, 4 über Leitungen 28 bzw. 29 gesteuert.From the chain 8 are a number, for. B. a hundred warp threads 15 guided over a feeler roller 16. Correspondingly, a number of warp threads 17 of the chain 9 are passed over a feeler roller 18. Each roller 16, 18 is attached to a leaf spring 20, which is attached at 19 in a shoe 21. The shoe 21 is fastened on the deflection roller 13 by means of a screw connection 22. The shoe 21 also carries a sensor 23, which is connected via an electrical line 24 to a partial control device 25 assigned to the partial warp beam 3. In a corresponding manner, the feeler roller 18 is fastened on the deflection roller 13 and a control line 26 is guided to a part control device 27 assigned to the part warp beam 4. The drive motors 5, 6 of the two warp beams 3, 4 are controlled by the control devices 25, 27 via lines 28 and 29, respectively.

Der Spannbaum 14 sitzt auf einem in Fig. 2 nur angedeuteten Schwenkhebel 31, der mit einem in einem ortsfesten Tragbaumrohr 32 angeordneten Torsionsfederstab 33 an dessen einem Ende verbunden ist. Der Torsionsfederstab 33 ist an seinem anderen Ende mit dem Maschinengestell 1, 2 verbunden (vgl. CH-PS 631 756 ; EP-Patentanmeldung 82/810448.9). Durch den am einen Ende tordierten Federstab 33 wird die Spannung der Ketten 8.9 aufgenommen.The tensioning tree 14 is seated on a pivot lever 31, which is only indicated in FIG. 2 and which has a torsion spring bar 33 arranged at one end thereof in a fixed supporting tree tube 32 is bound. The torsion spring rod 33 is connected at its other end to the machine frame 1, 2 (cf. CH-PS 631 756; EP patent application 82 / 810448.9). The tension of the chains 8.9 is absorbed by the spring rod 33 twisted at one end.

Der Spannbaum 14 kann z. B. durch entsprechende Vorspannung des Torsionsfederstabes 33 so eingestellt werden, dass er in der in Fig.2 ausgezogen wiedergegebenen Position steht. Die Kettfäden der Kette 8 des Teilkettbaumes 3 laufen auf direktem Weg von der Umlenkwalze 13 zum Spannbaum 14. Die Kettfäden 15 jedoch laufen unter einem gewissen Winkel über die Tastrolle 16. An dem Berührungspunkt D der Kettfäden 15 und der Tastrolle 16 ist in Fig. 2 das Kräfteparallelogramm eingezeichnet. Die beiden gleich grossen Kettspannungskräfte sind mit E, F bezeichnet. Aus ihnen entsteht die gegen den Sensor 23 hin gerichtete, resultierende Tastkraft G. Ihr Betrag kann z. B. etwa 20 % des Betrages der Spannungsverktoren E, F sein. Unter der Kraft G wird die Tastrolle 16 gegen die Wirkung der Feder 20 in Fig. nach links unten bewegt, wodurch sich Feder 20 dem Sensor 23 nähert. Dadurch wird ein Signal auf die Teilsteuereinrichtung 25 gegeben und von hier aus eine entsprechende Kettablassgeschwindigkeit des Teilkettbaumes 3 eingestellt.The spanning tree 14 can e.g. B. can be adjusted by appropriate preloading of the torsion spring rod 33 so that it is in the position shown in FIG. The warp threads of the chain 8 of the partial warp beam 3 run directly from the deflection roller 13 to the tensioning beam 14. However, the warp threads 15 run at a certain angle over the feeler roller 16. At the point of contact D of the warp threads 15 and the feeler roller 16 is in FIG. 2 the parallelogram of forces is drawn. The two chain tension forces of the same size are designated E, F. From them, the resulting sensing force G directed toward the sensor 23 arises. B. about 20% of the amount of the voltage verifiers E, F. Under the force G, the feeler roller 16 is moved against the action of the spring 20 to the left down in FIG. As a result, a signal is given to the partial control device 25 and from here a corresponding warp let-off speed of the partial warp beam 3 is set.

Die Kräfteverhältnisse an der Tastrolle 18 entsprechen denjenigen an der Tastrolle 16, wie in Fig.2 eingezeichnet.The force relationships on the feeler roller 18 correspond to those on the feeler roller 16, as shown in FIG.

Wenn z. B. die Spannung in der Kette 8 zunimmt und der Spannbaum 14 in Fig. 2 aus der strichpunktiert eingezeichneten Stellung 14a vorübergehend in eine punktiert eingezeichnete Stellung 14b verschwenkt wird, so wird über den zugehörigen Sensor 23 und die Teilsteuereinrichtung 25 sofort die Kettablassgeschwindigkeit am Teilbaum 3 erhöht. Dadurch, dass der Spannbaum die Position 14b besitzt, wird in der Kette 9 aus geometrischen Gründen die Spannung erniedrigt.If e.g. B. The tension in the chain 8 increases and the tensioning tree 14 in FIG. 2 is temporarily pivoted from the position 14a shown in dash-dotted lines to a position 14b shown in dotted lines, the warp let-off speed on the sub-tree 3 is immediately determined via the associated sensor 23 and the partial control device 25 elevated. Due to the fact that the spanning tree has the position 14b, the tension in the chain 9 is reduced for geometric reasons.

Ueber die Tastrolle 18 wird nunmehr ein entsprechend umgekehrtes Signal auf die Teilsteuereinrichtung 27 gegeben, wodurch sofort die Kettablassgeschwindigkeit am Teilkettbaum 4 erniedrigt wird. In beiden Ketten 8 ,9 entsteht daher in kürzester Zeit wieder die gewünschte, gleich grosse Kettspannung.A correspondingly reversed signal is now sent to the part control device 27 via the feeler roller 18, whereby the warp let-off speed on the part warp beam 4 is immediately reduced. In both chains 8, 9, the desired chain tension of the same size is therefore created again in the shortest possible time.

Die Einrichtung kann auch z. B. bei Webmaschinen mit drei Teilkettbäumen benutzt werden. Alsdann sind drei Tastrollen erforderlich, an jedem Teilkettbaum eine. Der Spannbaum 14 kann auch unter der Wirkung von zwei seitlich angeordneten Spiralfedern z. B. entsprechend DE-PS 1 138 715 stehen.The device can also, for. B. can be used in looms with three warp beams. Then three tracer rollers are required, one on each part of the warp beam. The spanning tree 14 can also under the action of two laterally arranged coil springs z. B. stand according to DE-PS 1 138 715.
