Description

Die Erfindung betrifft eine Einrichtung zum Speichern von fadenförmigem Material für den Schusseintrag bei Webmaschinen, mit einer umlaufenden, das Material tragenden Scheibe und einer darauf gerichteten Düse zum Zuführen von Luft und Material, ferner mit einer auf der Schußseite der Webmaschine angeordneten Öse zum Zuführen des von der Scheibe abgezogenen Materials in die Schusseintragsvorrichtung.The invention relates to a device for storing thread-like material for weft insertion in looms, with a rotating disk carrying the material and a nozzle directed thereon for supplying air and material, furthermore with an eyelet arranged on the weft side of the loom for supplying the the disc pulled material into the weft insertion device.

Ferner bezieht sich die Erfindung auf ein Verfahren für den Betrieb der Einrichtung.The invention further relates to a method for operating the device.

Bei einer Speichereinrichtung nach der DE-A-2 215 003 wird das zu speichernde Garn durch eine quer zur Umlaufrichtung der Scheibe hin und her bewegte Zuführdüse auf die Scheibe in Schlingenform aufgelegt. Das Garn wird nach der Speicherung im wesentlichen senkrecht zur Fläche der Trägerscheibe von dieser abgezogen. Die schlingenförmige Garnablage kann dabei leicht in Unordnung geraten, so dass sich einzelne Schlingen übereinander liegen können. Der Abzug des gespeicherten Garnes kann dadurch gestört werden, weil häufig mehrere, übereinander liegende Schlingen zu gleicher Zeit abgezogen werden können anstatt hintereinander. Auch ist bei dieser Ausführungsform ein senkrechter Abzug von der Trägerscheibe erforderlich, weil bei in der Scheibenebene verlaufenden Abzug in stärkerem Mass übereinanderliegende Garnschlingen zu gleicher Zeit abgezogen würden.In the case of a storage device according to DE-A-2 215 003, the yarn to be stored is placed in a loop shape on the disk by a feed nozzle which is moved back and forth transversely to the direction of rotation of the disk. After being stored, the yarn is drawn off the carrier disk essentially perpendicular to the surface thereof. The loop-shaped yarn deposit can easily get messy, so that individual loops can lie on top of each other. The withdrawal of the stored yarn can be disturbed because often multiple loops lying one above the other can be removed at the same time instead of one after the other. In this embodiment, too, a vertical take-off from the carrier disk is required, because with the take-off running in the disk plane, twine loops lying one above the other would be taken off at the same time.

Der Erfindung liegt die Aufgabe zugrunde, eine besonders in dieser Hinsicht verbesserte Speichereinrichtung zu schaffen.The object of the invention is to create a storage device which is particularly improved in this regard.

Die erfindungsgemässe Einrichtung besteht darin, dass auf der Scheibe ein unter geringer Andrückkraft gegen sie gedrücktes, vorzugsweise unter seinem Eigengewicht auf ihr liegendes Abdeckelement angeordnet ist, unter dem das Material auf der Scheibe in Form einer schlingenförmigen Ablage speicherbar ist.The device according to the invention consists in that a cover element, which is pressed against it under low pressure, preferably under its own weight, is arranged on the disc, under which the material on the disc can be stored in the form of a loop-shaped deposit.

Das zugehörige Betriebsverfahren besteht darin, dass die Drehzahl der Scheibe und die Zuführgeschwindigkeit des auf ihr zu speichernden Materials so aufeinander abgestellt sind, dass das Ende der auf einer auf der Scheibe aufliegenden ringförmigen Auflage gespeicherten, schlingenförmigen Materialablage höchstens bis in den Bereich des Schnittpunktes der von der Zuführöse an die Mittellinie der Auflage gelegten Tangente liegt.The associated operating method consists in that the rotational speed of the disk and the feed speed of the material to be stored on it are adjusted to one another in such a way that the end of the loop-shaped material deposit stored on an annular support resting on the disk is at most up to the area of the intersection of the the feed eye lies on the center line of the support tangent.

Wie der Versuch ergibt, lässt sich durch das Abdeckelement eine besonders gleichmässige Schlingenablage ohne Fadenverwirrung, z. B. Überwerfung einzelner Schlingen, erzielen. Insbesondere kann aber ein sauberer, geordneter Einlauf des aus der Zuführdüse kommen den, auf die Scheibe aufzulegenden Materials, beispielsweise Fadens, erreicht werden. Die Zuführdüse und damit die Einlaufpartie des Fadens liegt in einem zweckmässigen, der Zuführöse zugekehrten Sektor wodurch sich erzielen lässt, dass bei Fadenabzug während des Schusseintrages die gespeicherte Ablage vollständig aufgebraucht werden kann und noch ein geringes Stück Faden unmittelbar aus der Zuführdüse nachgezogen werden kann. Dabei ist eine in der der Ebene der Speicherscheibe liegende Abzugsrichtung vorteilhaft, wodurch eine besonders sichere Arbeitsweise erreicht wird.As the experiment shows, the cover element can be used to deposit the loops in a particularly uniform manner without tangling the thread, e.g. B. Throwing single loops. In particular, however, a clean, orderly intake of the material to be placed on the disk, for example thread, coming from the feed nozzle can be achieved. The feed nozzle and thus the inlet section of the thread lie in an appropriate sector facing the feed eyelet, which means that when the thread is drawn off during the weft insertion, the stored deposit can be completely used up and a small piece of thread can be drawn directly from the feed nozzle. In this case, a withdrawal direction lying in the plane of the storage disk is advantageous, as a result of which a particularly safe operation is achieved.

Der Deckel kann sich vorteilhaft über einen der Zuführöse zugekehrten Sektor von beispielsweise 120° über der Scheibe erstrecken, wobei sich die Fadenablage über ca. 90° erstreckt. Dadurch wird in vorteilhafter Weise bei Eintragsbeginn der Faden aus einem Abschnitt der Trägerscheibe gezogen, welcher im Bereich des Schnittpunktes der von der Zufütöse an die Mittellinie einer auf der Scheibe aufgelegten, ringförmigen Auflage gelegten Tangente liegt. Der Abzugswiderstand wird dann relativ gering, weil der abzuziehende Faden nur auf einem verhältnismässig kurzen Stück der Trägerscheibe aufliegt.The cover can advantageously extend over a sector facing the feed eyelet, for example 120 ° above the disk, the thread deposit extending over approximately 90 °. As a result, at the start of entry, the thread is advantageously drawn from a section of the carrier disk which lies in the region of the intersection of the tangent placed by the feed eyelet on the center line of an annular support placed on the disk. The pull-off resistance then becomes relatively low because the thread to be pulled rests only on a relatively short piece of the carrier disk.

Auf einem an der nur schusseitig dargestellten Webmaschine 46 angebrachten Gestell 1 ist eine tellerförmige Trägerscheibe 2 (Durchmesser z. B. 140 mm) drehbar gelagert, die über einen Endlosriementrieb 3 und eine Rolle 4 vom Webmaschinenantrieb aus in kontinuierliche Drehung versetzt ist. Die Scheibe 2 trägt z. B. im äusseren Teil eine mit Borsten 20 versehene Auflage 5 z. B. aus Velour, Nadelfilz oder dgl., auf welche ein aus einer Zuführdüse 6 kommender Faden 7 während der Drehung (Pfeil 22) in einer schlingenförmigen Fadenablage 8 aufgelegt werden kann. Der Faden 7 wird über eine kontinuierlich drehende, synchron vom Webmaschinenantrieb angetriebene Zumesstrommel 11, eine Förderdüse 30 und ein Zuführungsrohr 12 zu der Düse 6 geführt. Dabei wird der Faden von einer nicht dargestellten Spule der Webmaschine abgezogen.A plate-shaped carrier disk 2 (diameter, for example, 140 mm) is rotatably mounted on a frame 1 attached to the loom 46 shown only on the weft side, which is set in continuous rotation by means of an endless belt drive 3 and a roller 4 from the loom drive. The disc 2 carries z. B. in the outer part of a bristle 20 rest 5 z. B. from velor, needle felt or the like., On which a coming from a feed nozzle 6 thread 7 can be placed during the rotation (arrow 22) in a loop-shaped thread tray 8. The thread 7 is fed to the nozzle 6 via a continuously rotating metering drum 11, which is driven synchronously by the weaving machine drive, a feed nozzle 30 and a feed tube 12. The thread is drawn off a spool of the weaving machine, not shown.

Oberhalb der Auflage 5 ist ein sich über einen der Zuführöse 26 zugekehrten Sektor B von ca. 120° erstreckendes Abdeckelement 13 angeordnet. Der Deckel ist in einem Lager 14 gehalten, das auf einer Stange 15 drehbar angeordnet ist. Diese ist in einem am Gestell 1 angeordneten Support 16 befestigt. Der Deckel 13 ist somit entsprechend Pfeil 17 um 15 schwenkbar. Er ist mit Vorteil durchsichtig und besteht z. B. aus Plexiglas.Above the support 5 there is a cover element 13 which extends over a sector B facing the feed eyelet 26 and extends approximately 120 °. The lid is held in a bearing 14 which is rotatably arranged on a rod 15. This is fastened in a support 16 arranged on the frame 1. The lid 13 is thus pivotable by 15 according to arrow 17. It is advantageously transparent and consists, for. B. made of plexiglass.

Die der Zuführdüse 6 zugekehrte Kante 21 des Deckels 13 ist in Richtung des Umlaufes der Scheibe 2 (Pfeil 22) unmittelbar nach der Düse 6 angeordnet. An die Kante 21 schliesst sich ein metallischer Teil 48 an. Die Endkante des Deckels 13 ist mit 10 bezeichnet. Durch sie bzw. das Lager 14 wird die maximal nutzbare Bogenlänge C der Ablage 8 bestimmt.The edge 21 of the cover 13 facing the feed nozzle 6 is arranged in the direction of the circulation of the disc 2 (arrow 22) immediately after the nozzle 6. A metallic part 48 adjoins the edge 21. The end edge of the cover 13 is designated 10. The maximum usable arc length C of the tray 8 is determined by them or the bearing 14.

Die Düse 6 ist auf dem einen Schenkel 24 eines Winkels A zwischen der Verbindungslinie 25 von Zuführöse 26 der Webmaschine 46 und der Achse 23 der Scheibe 2 angeordnet. Sie liegt innerhalb eines Sektors von etwa 30°, gemessen von der Verbindungslinie 25 in Richtung entgegengesetzt zu Pfeil 22.The nozzle 6 is arranged on one leg 24 of an angle A between the connecting line 25 of the feed eyelet 26 of the weaving machine 46 and the axis 23 of the disk 2. It lies within a sector of approximately 30 °, measured from the connecting line 25 in the direction opposite to arrow 22.

Die Zuführöse 26 der Webmaschine 46 enthält eine Fadenbremse 27, die über ein Gestänge 28 gemäss Pfeil 29 zu betätigen ist. Die Hauptdüse 31 für den Schusseintrag sitzt auf der Lade 32 der Webmaschine, die über eine Hohlwelle 33 in Hin-und Herbewegung entsprechend Pfeil 34 versetzt wird. Das Riet ist mit 35, die Schusslinie mit 36 und der Fadenführungskanal mit 37 bezeichnet.The feed eyelet 26 of the weaving machine 46 contains a thread brake 27 which can be actuated via a linkage 28 according to arrow 29. The main nozzle 31 for the weft insertion sits on the drawer 32 of the weaving machine, which is moved back and forth according to arrow 34 via a hollow shaft 33. The reed is labeled 35, the weft line 36 and the thread guide channel 37.

Die durch den Antrieb bei 3,4 erzielte Drehzahl (z. B. 200 min-1) der Scheibe 2 und die durch die Zumesstrommel 11 verursachte Zuführungsgeschwindigkeit (z. B. 18m/sec) des Fadens 7 sind so aufeinander abgestellt, dass das Ende 41 der Schlingenablage 8 im Bereich des Schnittpunktes 42 der von der Zuführöse 26 an die Mittellinie 40 der Auflage 5 gelegten Tangente 43 liegt.The speed (e.g. 200 min- 1 ) of the disk 2 achieved by the drive at 3.4 and the feed speed (e.g. 18m / sec) of the thread 7 caused by the metering drum 11 are adjusted to one another such that the End 41 of the loop holder 8 lies in the area of the intersection 42 of the tangent 43 placed by the feed eyelet 26 on the center line 40 of the holder 5.

Wenn der Eintrag bei der Stellung der Teile nach Fig. 2 beginnt, liegt der Schussfaden 7 in der Tangente 43. Nunmehr erhält die Hauptdüse 31 Luft, so dass der Schussfaden 7 zunächst am Ende 41 der Auflage 8 abgezogen wird. Durch die Düse 6 wird weiterhin kontinuierlich Faden auf die Scheibe 2 abgelegt und diese dabei weitergedreht. Der Schusseintrag verläuft so rasch, dass während der Bewegung der Öse 26 aus der hinteren, vom Gewebeanschlag am weitesten entfernten, in Fig. 2 oberen Stellung in Richtung auf die vordere Umkehrposition 26a während des Anschlages der gesamte Faden aus der Fadenablage 8 verbraucht und noch ein Stück aus dem Rohr 12 nachgezogen wird. Bei Ende des Schusseintrages wird der eingetragene Faden 7 durch die Fadenbremse 27 gebremst. Nunmehr wird eine neue Fadenablage 8 auf die Scheibe 2 abgelegt.2, the weft thread 7 lies in the tangent 43. The main nozzle 31 now receives air, so that the weft thread 7 is first drawn off at the end 41 of the support 8. Through the nozzle 6, thread is continuously deposited on the disc 2 and this is rotated further. The weft insertion is so rapid that during the movement of the eyelet 26 from the rear position, which is the most distant from the tissue stop, in FIG. 2, the upper position in the direction of the front reversing position 26a, the entire thread from the thread rest 8 is used up and still in during the stop Pieces from the tube 12 is drawn. At the end of the weft insertion, the thread 7 is braked by the thread brake 27. Now a new thread tray 8 is placed on the disc 2.

Bei der abgewandelten Ausführungsform nach Fig. 3 ist das Abdeckelement 13 schwimmend gelagert, d.h. es wird durch die Welle 15 lediglich daran gehindert, der Drehung der Scheibe 2 zu folgen. Das Lager 14a ist oben offen.In the modified embodiment according to Fig. 3, the cover member 13 is floating, i.e. it is only prevented by the shaft 15 from following the rotation of the disc 2. The bearing 14a is open at the top.

Wie ersichtlich, wird der aus der Fadenauflage 8 abgezogene Faden 7 in der Ebene der Scheibe 2 von Scheibe 2 abgezogen, nicht etwa senkrecht zu der Scheibe 2.As can be seen, the thread 7 withdrawn from the thread support 8 is pulled off the disc 2 in the plane of the disc 2, not approximately perpendicular to the disc 2.

Bei einem abgewandelten Betriebsverfahren sind Drehzahl von Scheibe 2 und Zuführgeschwindigkeit von Faden 7 durch Düse 6 so aufeinander abgestellt, dass die Fadenauflage 8 weniger als der in Fig. 2 dargestellte Bogen C von ca. 90° beträgt, z. B. nur etwa 60°. Die Ablage 8 soll nicht wesentlich über den Schnittpunkt 42 hinausreichen, weil sonst der Faden 7 zu Beginn des Schusseintrages über ein grösseres Stück der Auflage 5 unter erhöhter Reibung gezogen werden müsste. Auch bestünde dabei ein erhöhtes Risiko für Fadenverwirrung.In a modified operating method, the speed of the disk 2 and the feed speed of the thread 7 through the nozzle 6 are adjusted to one another in such a way that the thread support 8 is less than the arc C shown in FIG. B. only about 60 °. The rest 8 should not extend far beyond the intersection 42, because otherwise the thread 7 would have to be pulled over a larger piece of the rest 5 with increased friction at the beginning of the weft insertion. There would also be an increased risk of thread confusion.

Während bei dem geschilderten Beispiel der Auflage 5 angenommen ist, dass die Auflage aus einem mehr oder weniger luftundurchlässigen Material besteht und die Luft unter Änderung ihrer Strömungsrichtung in Richtung parallel zur Scheibenebene (in Fig. 2 = Zeichenebene) abströmt, kann bei einer anderen Bauart auch eine luftdurchlässige, z. B. siebartige Auflage 5 verwendet werden, durch die die abströmende Luft hindurchtreten kann.While in the example of the support 5 described it is assumed that the support consists of a more or less air-impermeable material and the air flows out with a change in its direction of flow in the direction parallel to the pane plane (in FIG. 2 = drawing plane), another design can also an air permeable, e.g. B. sieve-like pad 5 can be used through which the outflowing air can pass.

Di Bogenlänge C der Fadenablage 8 kann z. B. bei gleicher Drehzahl von Scheibe 2 und gleicher Zuführungsgeschwindigkeit des Fadens 7 durch die Düse 6 auch kürzer sein, wenn beispielsweise geringere Eintragslänge (Webbreite) an der Webmaschine vorliegt. Dagegen kann zur Erzielung dieser geringeren Eintragslänge die Bogenlänge der Fadenablage 8 gleich dem Betrag C sein, wenn die Drehzahl der Scheibe 2 entsprechend erhöht wird. Die einzelnen Schlingen der Ablage 8 sind in diesem Fall weiter auseinander gezogen, so dass sie weniger dicht aneinander liegen.Di arc length C of the thread tray 8 can, for. B. at the same speed of the disc 2 and the same feed speed of the thread 7 through the nozzle 6 may also be shorter if, for example, a smaller entry length (weaving width) is present on the weaving machine. In contrast, to achieve this shorter entry length, the arc length of the thread deposit 8 can be equal to the amount C if the speed of the disk 2 is increased accordingly. In this case, the individual loops of the shelf 8 are pulled further apart, so that they lie less close together.

Bei einer Ausführungsform steht die Achse 23 statt in der in Fig. 1 vorgesehenen Vertikalstellung in horizontaler Position, so dass die Ebene der Scheibe 2 vertikal steht; der Deckel 13 ist dann unter geringer Kraft, z. B. von einer oder mehreren Federn, gegen die Auflage 5 gedrückt.In one embodiment, the axis 23 is in a horizontal position instead of in the vertical position provided in FIG. 1, so that the plane of the disk 2 is vertical; the lid 13 is then under low force, for. B. of one or more springs, pressed against the pad 5.

Die Achse 23 kann in Fig. 2 auch oberhalb oder unterhalb der Verbindungslinie 25 stehen, so dass die Scheibe 2 in Fig. 2 höher oder tiefen stehen kann.The axis 23 can also be above or below the connecting line 25 in FIG. 2, so that the disk 2 in FIG. 2 can be higher or lower.
