Die Freigabe einer Fadenlage für den Eintrag in die Webmaschine wird durch eine Klemmeinrichtung am ablaufseitigen Ende der Trommel (24) bestimmt, welche aus einem Hebel (14) und einem Auflagestück (15a) ausserhalb der Trommel (24) gebildet wird. Das Auflagestück ist federnd in einem Haltestück (16) gelagert, dass die Trommel (24) gegen Verdrehung sichert. Die Klemmeinrichtung (14, 15a) ermöglicht bei kleinem Bauraum ein schonendes Festhalten des Schussfadens.In a weft store for a weaving machine with a stationary drum (24) and with a winding arm (3) for winding weft yarn (20) onto the circumference of the drum, layers of thread turns (21, 22) are separated from one another by a separating device (11). The release of a thread layer for entry into the weaving machine is determined by a clamping device at the outlet end of the drum (24), which is formed from a lever (14) and a support piece (15a) outside the drum (24). The support piece is resiliently mounted in a holding piece (16) that secures the drum (24) against rotation. The clamping device (14, 15a) enables the weft thread to be held firmly in a small space.

Description

Die Erfindung betrifft einen Schussfadenspeicher für eine Webmaschine mit stillstehender Trommel und mit einem Wickelarm zum Aufwickeln von Schussgarn auf den Umfang der Trommel, mit einer Separiereinrichtung für mehrere Lagen von Fadenwindungen, deren Gesamtlänge gleich der Eintragslänge des Schussfadens in das Fach der Webmaschi­ne ist, und mit einer Einrichtung zum Klemmen des Schuss­fadens am ablaufseitigen Ende der Trommel, wobei der Schussfaden mittels eines Klemmorgans am Trommelumfang festgehalten wird.The invention relates to a weft thread storage device for a weaving machine with a stationary drum and with a winding arm for winding weft yarn onto the circumference of the drum, with a separating device for several layers of thread turns, the total length of which is equal to the insertion length of the weft thread into the loom compartment, and with a device for clamping the weft thread at the outlet end of the drum, the weft thread being held on the drum circumference by means of a clamping element.

Ein derartiger Speicher ist aus der japanischen Utility Model Publication No. 7265/86 bekannt. Ein ausserhalb der Trommel angeordneter Hebel drückt den Schussfaden auf den Umfang der Trommel, solange kein Faden von der Trommel ab­gezogen werden soll. Der mechanische Antrieb des Hebels erfordert eine separate Lagerung der Antriebswelle und da­mit zusätzlichen Bauraum in der Peripherie der Speicher­trommel. Der Hebel schlägt mit seinem Ende unmittelbar auf der Trommel auf, wodurch empfindliches Schussgarn beim Festklemmen beschädigt werden kann.Such a memory is from the Japanese Utility Model Publication No. 7265/86 known. A lever located outside the drum presses the weft thread around the circumference of the drum as long as no thread is to be pulled off the drum. The mechanical drive of the lever requires a separate mounting of the drive shaft and thus additional space in the periphery of the storage drum. The end of the lever hits the drum directly, which can damage delicate weft yarn when it is clamped.

Es ist Aufgabe der vorliegenden Erfindung, einen Schuss­fadenspeicher zu schaffen, dessen Einrichtung zum Klemmen des Fadens in den Speicher integriert ist und ein schonen­des Festhalten des Schussfadens ermöglicht.It is an object of the present invention to provide a weft store, the device for clamping of the thread is integrated in the memory and allows the weft thread to be held gently.

Die Erfindung, welche diese Aufgabe löst, ist dadurch ge­kennzeichnet, dass im Inneren der Trommel ein Klemmorgan nach aussen gegen den Schussfaden am Trommelumfang heran­führbar angeordnet ist und dass ausserhalb der Trommel ein Klemmelement für den Schussfaden vorgesehen ist, das ein gefedertes Auflagestück für den Schussfaden und das Klemm­organ aufweist. Das Klemmelement ist in einem Haltestück untergebracht, das die Speichertrommel gegen Verdrehung sichert. Das Auflagestück ist im Haltestück verschiebbar gelagert. Es kann aus gummielastischem Werkstoff herge­stellt sein und federnd abgestützt sein. Für den Antrieb des Klemmorgans kann ein drehbar gelagerter Hebel mit einer Rolle vorgesehen werden, wobei die Rolle auf einer Kurvenscheibe auf der Antriebswelle der Separiereinrich­tung läuft. Der Hebel kann auch durch einen Elektromag­neten nach aussen gegen das Klemmelement gezogen werden, wobei er in seiner äusseren Lage sowohl gegen einen starren Anschlag als auch gegen das Auflagestück drückt.The invention, which solves this problem, is characterized in that inside the drum a clamping member can be arranged outwardly against the weft thread on the drum circumference and that outside the drum a clamping element for the weft thread is provided, which has a spring-loaded support piece for the weft thread and has the clamping member. The clamping element is housed in a holding piece that secures the storage drum against rotation. The support piece is slidably mounted in the holding piece. It can be made of rubber-elastic material and be spring-supported. A rotatably mounted lever with a roller can be provided for driving the clamping member, the roller running on a cam on the drive shaft of the separating device. The lever can also be pulled outwards against the clamping element by an electromagnet, and in its outer position it presses both against a rigid stop and against the support piece.

Der Schussfadenspeicher mit der Klemmeinrichtung gemäss der Erfindung nimmt praktisch denselben Bauraum wie ein Schussfadenspeicher ohne diese Einrichtung in Anspruch. Es können damit auch empfindliche Schussgarne verarbeitet werden, ohne dass beim Klemmen das Garn verletzt wird.The weft store with the clamping device according to the invention takes up practically the same space as a weft store without this device. It can also be used to process sensitive weft yarns without damaging the yarn during clamping.

Im folgenden wird die Erfindung anhand der Figuren näher beschrieben.

  • Fig. 2a, 2b zeigen zwei Ausführungsformen des Klemm­ elements,
  • Fig. 3 zeigt das Klemmelement und einen Teil des Klemmorgans in der Arbeitsstellung,
  • Fig. 4 stellt das Haltestück für Separiereinrich­tung und Klemmelement dar,
  • Fig. 5 beinhaltet einen elektromagnetischen An­trieb für das Klemmorgan.
The invention is described in more detail below with reference to the figures.
  • 1 shows a meridian section through the memory,
  • 2a, 2b show two embodiments of the clamp elements,
  • 3 shows the clamping element and part of the clamping member in the working position,
  • 4 shows the holding piece for separating device and clamping element,
  • Fig. 5 includes an electromagnetic drive for the clamping member.

Der Schussfadenspeicher 1 trägt in einem Gehäuse 2 einen Wickelarm 3 mittels einer Lagerung 4. In der Achse des Wickelarms 3 läuft der Schussfaden 20 zu. Er wird in einem ersten Wickel 21 und einem zweiten Wickel 22 auf der Trom­mel 24, welche durch Bügel 7 erweitert wird, abgelegt. Ein Speicher dieser Bauart mit einer Trommel 24 und zu­sätzlichen Bügeln 7 ist beispielsweise in der schweizeri­schen Patentschrift 639 711 beschrieben. Die Trommel wird durch eine Scheibe 8 zusammen mit den Bügeln 7 getragen. Die Trommel 24 ist mittels eines Lagers 9b auf einer Welle 9a abgestützt, die zusammen mit dem Wickelarm 3 rotiert. Ueber die Schnecke 9 wird ein Schneckenrad 10 und damit verbunden ein Klauenrad 11 der Separiereinrichtung für die Schussfadenwickel 21 und 22 sowie die Kurvenscheibe 12 an­getrieben. Das Klauenrad 11, welches in der Trommel 24 auf der Welle 30 gelagert ist, sichert die Trommel 24 gegen Verdrehung, da es im Schlitz 18 des Haltestücks 16 läuft, welches am Gehäuse 2 befestigt ist.The weft store 1 carries a winding arm 3 in a housing 2 by means of a bearing 4. The weft 20 runs in the axis of the winding arm 3. It is deposited in a first roll 21 and a second roll 22 on the drum 24, which is expanded by brackets 7. A memory of this type with a drum 24 and additional brackets 7 is described for example in the Swiss patent 639 711. The drum is carried by a disc 8 together with the brackets 7. The drum 24 is supported by a bearing 9b on a shaft 9a which rotates together with the winding arm 3. A worm wheel 10 and, connected to it, a claw wheel 11 of the separating device for the weft thread windings 21 and 22 and the cam disc 12 are driven via the worm 9. The claw wheel 11, which is mounted in the drum 24 on the shaft 30, secures the drum 24 against rotation since it runs in the slot 18 of the holding piece 16, which is fastened to the housing 2.

Im Inneren der Trommel 24 ist weiterhin das Klemmorgan 14 in Form eines Rollenhebels gelagert. Die Rolle 13 am Hebel 14 läuft auf der rotierenden Kurvenscheibe 12 und bewegt damit den Hebel 14 gegen den Druck der Feder 27 gegen das Klemmelement 15 hin und her. Das Klemmelement 15 ist im Haltestück 16 untergebracht. Das Auflagestück 15a im Klemm­element 15 kann mittels einer Torsionsfeder 19a oder einer Biegefeder 16b gemäss Fig. 2a bzw. 2b gegen die Anschlag­fläche 15c in Fig. 3 gedrückt werden. Das Auflagestück 15a kann aus gummielastischem Material gefertigt sein. Es kann auch ohne Feder 19a bzw. 16b verwendet werden, wenn es deren Raum im Klemmelement 15 ausfüllt. Für be­stimmte Garne kann es zweckmässig sein, das Auflagestück 15a mit einer Auflageplatte 15b beispielsweise aus Keramik zu versehen. Durch die Berührung des Klemmorgans 14 mit dem Auflagestück 15 wird dieses in der Bohrung 17 ver­schoben, wenn das ablaufende Fadenstück 23 festgeklemmt wird. Durch die Wahl der Federkonstante der Federn 19a bzw. 19b kann die Klemmkraft des Fadenstücks 23 genau festgelegt werden. Da das Auflagestück 15a relativ klein und massenarm ist, wird der Faden 23 beim Auftreffen des Klemmorgans 14 auf dem Auflagestück 15a sanft festgeklemmt. In Fig. 5 ist eine magnetische Betätigung des Klemmorgans 14 gezeigt. Der Elektromagnet 28 vermag den Hebel 14 aus seiner strichpunktierten Lage in die ausgezogene Lage am Anschlag 29 zu ziehen. Wenn der Magnet 28 stromlos ist, wird das Klemmorgan 14 mit Hilfe der Feder 27 gegen den Anschlag 26 im Inneren der Trommel zurückgezogen. Das Klemmorgan 14 liegt hier im wesentlichen in einem Schlitz 25 der Trommel 24.Inside the drum 24, the clamping member 14 is also mounted in the form of a roller lever. The roller 13 on the lever 14 runs on the rotating cam 12 and thus moves the lever 14 back and forth against the pressure of the spring 27 against the clamping element 15. The clamping element 15 is accommodated in the holding piece 16. The support piece 15a in the clamping element 15 can by means of a torsion spring 19a or Bending spring 16b according to FIGS. 2a and 2b are pressed against the stop surface 15c in FIG. 3. The support piece 15a can be made of rubber-elastic material. It can also be used without a spring 19a or 16b if it fills the space in the clamping element 15. For certain yarns, it may be expedient to provide the support piece 15a with a support plate 15b, for example made of ceramic. By touching the clamping member 14 with the support piece 15, this is moved in the bore 17 when the running thread piece 23 is clamped. The clamping force of the thread piece 23 can be precisely determined by the choice of the spring constant of the springs 19a or 19b. Since the support piece 15a is relatively small and low in mass, the thread 23 is gently clamped when the clamping member 14 strikes the support piece 15a. 5 shows a magnetic actuation of the clamping member 14. The electromagnet 28 is able to pull the lever 14 from its dot-dash position into the extended position at the stop 29. When the magnet 28 is de-energized, the clamping member 14 is withdrawn by means of the spring 27 against the stop 26 inside the drum. The clamping member 14 is here essentially in a slot 25 of the drum 24.

Die Arbeitsweise des Speichers ist beispielsweise in der schweizerischen Patentschrift 639 711 beschrieben. Die Klemmeinrichtung, bestehend aus dem Klemmorgan 14 und dem Klemmelement 15, bestimmt die Freigabe des Schussfadens 23 bzw. des zweiten Schussfadenwickels 22 zum Ablauf von der Trommel, wenn dieser Fadenwickel durch die Separier­einrichtung 11 in Richtung auf das abzugsseitige Ende der Trommel 24 geschoben worden ist. Der Abzug des Schussfadens 22 ist beendet, sobald sämtliche Windungen des Fadens in diesem Abschnitt von der Trommel abgezogen sind. Danach wird das Klemmorgan 14 wieder gegen das Klemmelement 15 bewegt, um den Faden 23 erneut festzuhalten.The operation of the memory is described for example in the Swiss patent 639 711. The clamping device, consisting of the clamping member 14 and the clamping element 15, determines the release of the weft thread 23 or the second weft thread winding 22 for the discharge from the drum when this thread winding has been pushed by the separating device 11 in the direction of the end of the drum 24 on the take-off side . The withdrawal of the weft thread 22 is finished as soon as all turns of the thread in this section are removed from the drum. Then the clamping member 14 is moved again against the clamping element 15 in order to hold the thread 23 again.
