Description

Die Erfindung betrifft eine Vorrichtung zur zwangsweisen Zulieferung von Elastomerfäden an Textilmaschinen, mit einem frei drehbaren Halter für eine Garnspule, die gegen eine Antriebswalze anliegt, und mit Rollen zur Führung des von der Garnspule abgezogenen Elastomerfadens.The invention relates to a device for the compulsory delivery of elastomer threads to textile machines, with a freely rotatable holder for a bobbin, which bears against a drive roller, and with rollers for guiding the elastomer thread drawn off the bobbin.

Eine Vorrichtung der eingangs genannten Art ist durch die US-PS 39 01 052 bekannt. Bei dieser Vorrichtung ist die Garnspule auf einen Halter aufgesteckt, dessen Träger durch eine Zugfeder senkrecht zur Achse einer Antriebswalze verstellbar ist, gegen welche die aufgesteckte Garnspule über ihre ganze Wickellänge anliegt. Diese Vorrichtung ist speziell für Elastomerfäden gedacht und muß bei der Verwendung normaler Fäden gegen andere Fadenliefervorrichtungen, die eine Fadenspeichertrommel aufweisen, ausgetauscht werden. Bei dieser Vorrichtung nimmt die Spule eine konstante Anlageposition zur Antriebswalze ein, wobei die Gefahr besteht, daß sich lose Garnfasern um die Antriebswalze legen und einen unerwünschten Belag auf der Antriebswalze bilden. Um dies zu verhindern, müssen die Antriebswalzen von Zeit zu Zeit gereinigt werden, da ein Antriebswalzenbelag die äußere Garnschicht der anliegenden Spule beschädigen und die Umfangsgeschwindigkeit der Garnspule und damit die Fadenabzugsgeschwindigkeit in unerwünschter Weise beeinflussen kann.A device of the type mentioned is known from US-PS 39 01 052. In this device, the thread spool is placed on a holder, the support of which can be adjusted by a tension spring perpendicular to the axis of a drive roller against which the thread spool placed rests over its entire winding length. This device is specially designed for elastomer threads and must be replaced when using normal threads with other thread delivery devices that have a thread storage drum. In this device, the bobbin assumes a constant contact position with the drive roller, with the risk that loose yarn fibers will wrap around the drive roller and form an undesirable coating on the drive roller. In order to prevent this, the drive rollers must be cleaned from time to time, since a drive roller coating can damage the outer yarn layer of the adjacent bobbin and can undesirably influence the peripheral speed of the yarn bobbin and thus the thread take-off speed.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß sie betriebssicherer und leichter auswechselbar ist.The invention has for its object to provide a device of the type mentioned so that it is more reliable and easier to replace.

Die gestellte Aufgabe wird mit einer Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Antriebswalze mit der Antriebsvorrichtung einer Fadenliefervorrichtung, beispielsweise koaxial und drehfest mit einer mit der Antriebsvorrichtung gekoppelten Speichertrommel der Fadenliefervorrichtung, verbunden ist und eine größere Länge als die Anlagelänge der Garnspule aufweist, und daß der Spulenhalter an einem Träger gelagert ist, der entlang einer Linie verschiebbar angeordnet ist, die unter einem spitzen Winkel zu der Antriebswalzenachse verläuft. Dabei können der Träger für den Spulenhalter und die Antriebswalze als Zusatzteile an den Teilen der auch an sich bekannten und für Normalfäden vorgesehenen Fadenliefervorrichtung lösbar verbunden sein.The stated object is achieved according to the invention with a device of the type mentioned at the outset in that the drive roller is connected to the drive device of a thread delivery device, for example coaxially and in a rotationally fixed manner, to a storage drum of the thread delivery device coupled to the drive device and has a greater length than the contact length of the yarn package , and that the bobbin holder is mounted on a carrier which is arranged displaceably along a line which runs at an acute angle to the drive roller axis. The carrier for the bobbin holder and the drive roller can be detachably connected as additional parts to the parts of the thread delivery device which is also known per se and is intended for normal threads.

Die erfindungsgemäß ausgebildete Vorrichtung ist raumsparend mit einer für Normalfäden vorgesehenen Fadenliefervorrichtung koppelbar. Bei der Verarbeitung von Elastomerfäden, beispielsweise an einzelnen Systemen einer mehrsystemigen Rundstrickmaschine, muß an den betreffenden Systemen kein Austausch der Fadenliefervorrichtungen vorgenommen werden, sondern werden die für die Elastomerspule vorgesehenen Halte-, Antriebs- und Führungsteile einfach an die bereits vorhandene Fadenliefervorrichtung angesetzt.The device designed according to the invention can be coupled in a space-saving manner with a thread delivery device provided for normal threads. When processing elastomeric threads, for example on individual systems of a multi-system circular knitting machine, there is no need to replace the thread delivery devices on the systems in question, but instead the holding, drive and guide parts provided for the elastomer bobbin are simply attached to the already existing thread delivery device.

Die schräge Anordnung des längsverschiebbaren Trägers für die Elastomerfadenspule bringt verschiedene Vorteile. Mit abnehmendem Garnspulendurchmesser erfolgt nicht nur eine Annäherung der Spulenachse gegen die Antriebswalzenachse, sondern gleichzeitig eine Längsverschiebung der Garnspule in Achsrichtung der Antriebswalze. Hierbei werden Ablagerungen, wenn sich solche auf der Oberfläche der Antriebswalze gebildet haben sollten, in Axialrichtung gelockert und abgeschoben, wodurch sich ein Selbstreinigungseffekt der Antriebswalze ergibt. Die schräge Anordnung begünstigt auch die Anbauverhältnisse dieser Vorrichtung im Hinblick auf einen geringen Platzbedarf sowohl in radialer als auch in axialer Richtung. Bei einem schräg nach unten verschiebbar angeordneten Träger kann eine selbsttätige Nachstellung der Garnspule unter ihrem Eigengewicht auch ohne Federunterstützung erreicht werden. Bei Textilmaschinen mit ungünstigen Platzverhältnissen an der Einbaustelle kann der Träger aber auch mittels Federkraft schräg nach oben verschiebbar angeordnet sein.The oblique arrangement of the longitudinally displaceable carrier for the elastomer thread spool brings various advantages. With a decreasing spool diameter, not only does the spool axis approach the drive roller axis, but at the same time there is a longitudinal displacement of the spool in the axial direction of the drive roller. Deposits, if such should have formed on the surface of the drive roller, are loosened and pushed off in the axial direction, resulting in a self-cleaning effect of the drive roller. The oblique arrangement also favors the mounting conditions of this device in terms of a small space requirement both in the radial and in the axial direction. In the case of a carrier which can be displaced obliquely downwards, an automatic readjustment of the yarn package under its own weight can also be achieved without spring support. In the case of textile machines with unfavorable space conditions at the installation site, the carrier can also be arranged so that it can be displaced obliquely upwards by means of spring force.

Theoretisch könnten auf dem Spulenhalter zwei oder mehr Elastomergarnspulen koaxial angeordnet und an der gemeinsamen Antriebswalze anliegend sein. Vorteilhafterweise wird die Vorrichtung jedoch mit nur einer einzigen Elastomergarnspule eingesetzt, weil dann an jeder Verarbeitungsstelle gleiche Fadenlaufstrecken zwischen der Garnspule und der Garnverarbeitungsstelle vorgegeben sind und die einzelnen Garnspulen einen unterschiedlichen Füllstand oder ein unterschiedliches Wickelvolumen aufweisen können. Die ganze Vorrichtung läßt sich konstruktiv einfach gestalten und so ausbilden, daß die Fadenliefervorrichtung auch mit Normalfaden unter Einsatz ihrer Fadenspeichertrommel betrieben werden kann, auch wenn die Halte-, Antriebs- und Führungsteile für den Elastomerfaden an der Vorrichtung montiert bleiben. Auch kann mit der Vorrichtung gewünschtenfalls gleichzeitig ein Normalfaden und ein Elastomerfaden zwangsweise einer oder zwei Verarbeitungsstellen zugeführt werden.Theoretically, two or more elastomer yarn bobbins could be arranged coaxially on the bobbin holder and adjoin the common drive roller. Advantageously, however, the device is used with only a single elastomer spool because then the same yarn paths between the yarn spool and the yarn processing point are specified at each processing point and the individual thread spools can have a different fill level or a different winding volume. The entire device can be structurally simple and designed so that the thread delivery device can also be operated with normal thread using its thread storage drum, even if the holding, drive and guide parts for the elastomer thread remain mounted on the device. If desired, a normal thread and an elastomer thread can also be forcibly fed to one or two processing points simultaneously with the device.

Nachfolgend wird ein Ausführungsbeispiel einer erfindungsgemäß ausgebildeten Fadenliefervorrichtung anhand der beiliegenden Zeichnung näher erläutert. Die Figur zeigt die Fadenliefervorrichtung in montiertem Zustand in Seitenansicht, teilweise im Schnitt.An exemplary embodiment of a thread delivery device designed according to the invention is explained in more detail below with reference to the accompanying drawing. The figure shows the thread delivery device in the assembled state in a side view, partly in section.

Die dargestellte Fadenliefervorrichtung weist ein als Hohlkörper ausgebildetes Vorrichtungsgehäuse 10 auf, das in seinem Endbereich an einer Montageschiene 11 einer Textilmaschine in Horizontallage angeschraubt ist. Im Gehäuse 10 ist eine nicht dargestellte, durchgehende, vertikal ausgerichtete Welle 16 gelagert, auf welcher auf der Unterseite des. Vorrichtungsgehäuses 10 eine Fadenspeichertrommel 12 befestigt ist, während auf der Oberseite des Vorrichtungsgehäuses 10 auf ihr zwei Riemenscheiben 13 und 14 gelagert sind, die mittels einer zwischen den beiden Riemenscheiben angeordneten, axialverstellbaren Kupplungsscheibe 15 wahlweise mit der Welle 16 kuppelbar sind über jede der Riemenscheiben 13, 14 ist ein Zahnriemen 17 oder 18 geführt, der mehreren gleichen Fadenliefervorrichtungen gemeinsam ist und von einer nicht dargestellten gemeinsamen Antriebsvorrichtung bewegt wird.The thread delivery device shown has a device housing 10 which is designed as a hollow body and which is screwed in its end region to a mounting rail 11 of a textile machine in a horizontal position. A continuous, vertically aligned shaft 16, not shown, is mounted in the housing 10, on which a thread storage drum 12 is fastened on the underside of the device housing 10, while on the top of the device housing 10, two pulleys 13 and 14 are mounted on it, which can be coupled to the shaft 16 by means of an axially adjustable coupling disc 15 arranged between the two pulleys. A toothed belt 17 or 18 is guided over each of the pulleys 13, 14, which is common to a plurality of identical thread delivery devices and is moved by a common drive device, not shown.

Am freien Ende des Vorrichtungsgehäuses 10 sind eine Fadenbremse 19, ein Knotenwächter 27, eine obere Fadenleitöse 20 und eine untere Fadenleitöse 23 angeordnet, die für einen mit einer strichpunktierten Linie angedeuteten Normalfaden 24 bestimmt sind, der in mehreren Windungen über die Speichertrommel 12 geführt werden soll und von der Speichertrommel über bügelartige Fadenleitelemente 25 und 26 und über einen nicht näher dargestellten Fadenbruchfühler abgezogen werden kann. Soweit ist die Fadenliefervorrichtung vorbekannt.At the free end of the device housing 10, a thread brake 19, a knot monitor 27, an upper thread guide eyelet 20 and a lower thread guide eyelet 23 are arranged, which are intended for a normal thread 24 indicated by a dash-dotted line, which is to be guided in several turns over the storage drum 12 and can be withdrawn from the storage drum via bow-like thread guide elements 25 and 26 and via a thread break sensor, not shown. So far, the thread delivery device is known.

Für die Lieferung eines Elastomerfadens ist die Fadenliefervorrichtung mit Zusatzteilen versehen. Am freien Endbereich des Vorrichtungsgehäuses 10 ist mittels einer auch zur Befestigung eines Halters für die obere Fadenleitöse 20 dienenden Schraube 28 ein abgewinkelter Tragarm 29 lösbar befestigt, der eine Durchgangsöffnung aufweist, über welcher eine Führungshülse 30 für einen längsverschiebbaren Stab 31 stirnseitig befestigt ist. Die Achse 32 der Führungshülse 30 und des Stabes 31 verlaufen unter einem Winkel a = 45° zu einer Vertikalen 33. Der längsverschiebbare Stab 31 dient als Träger für einen Garnspulen-Steckhalter 34, der am aus der Führungshülse 30 herausragenden freien unteren Ende des Stabes 31 mit vertikal ausgerichteter Achse 35 frei drehbar gehalten ist. Auf diesen Steckhalter 34 ist eine mit einem Elastomerfaden 37 bewickelte Garnspule 36 von unten reibungsschlüssig aufgesteckt.The thread delivery device is provided with additional parts for the delivery of an elastomer thread. At the free end area of the device housing 10, an angled support arm 29 is releasably attached by means of a screw 28 which is also used to fasten a holder for the upper thread guide eyelet 20 and which has a through opening, via which a guide sleeve 30 for a longitudinally displaceable rod 31 is fastened on the end face. The axis 32 of the guide sleeve 30 and the rod 31 extend at an angle a = 45 ° to a vertical 33. The longitudinally displaceable rod 31 serves as a carrier for a spool plug holder 34, which on the free lower end of the rod 31 protruding from the guide sleeve 30 is held freely rotatable with the axis 35 aligned vertically. A thread spool 36 wound with an elastomer thread 37 is frictionally attached to this plug holder 34 from below.

Der Stab 31 wird unter dem Gewicht des Garnspulen-Steckhalters 34 und der aufgesteckten Garnspule 36 in Anlage gegen eine Antriebswalze 38 gebracht die koaxial zur Speichertrommel 12 und damit auf der mit einer strichpunktierten Linie eingezeichnete Achse 39 der Welle 16 in Verlängerung der Speichertrommel 12 und mit ihr fest verbunden angeordnet ist. Die Antriebswalze 38 hat eine merklich größere Länge als die Anlagelänge der Garnspule 36. Die Anlage der Garnspule 36 wird noch durch eine Zugfeder 40 unterstützt, die mit ihrem einen Ende an der Führungshülse 30 und mit ihrem anderen Ende an einem mit der Stange 31 verbundenen und durch einen Längsschlitz 41 der Führungshülse 30 nach außen ragenden Bolzen 42 verankert. Die gesamte Trägervorrichtung ist mittels eines Schutzgehäuses 43 staubdicht abgedeckt, die als einfache Steckkapsel ausgebildet sein kann.The rod 31 is brought under the weight of the spool plug-in holder 34 and the attached spool 36 into contact with a drive roller 38 which is coaxial with the storage drum 12 and thus on the axis 39 of the shaft 16 drawn with a dash-dotted line in extension of the storage drum 12 and with her is firmly connected. The drive roller 38 has a noticeably greater length than the contact length of the thread spool 36. The thread of the thread spool 36 is also supported by a tension spring 40, which has one end connected to the guide sleeve 30 and the other end connected to the rod 31 anchored by a longitudinal slot 41 of the guide sleeve 30 protruding bolts 42. The entire carrier device is covered in a dustproof manner by means of a protective housing 43, which can be designed as a simple plug-in capsule.

Die Antriebswalze 38 kann einstückig mit der Speichertrommel 12 ausgebildet sein, vorteilhafterweise aber auch in hier nicht dargestellter Weise mit der Speichertrommel 12 lösbar verbunden sein, beispielsweise mittels einer Schraubverbindung oder einer bajonettverschlußartigen Drehsteckverbindung. Der Elastomerfaden 37 wird nicht über die Speichertrommel 12 geführt, wie ein Normalfaden 24, sondern über zwei Führungsrollen 44 und 45 abgezogen, die auf am Vorrichtungsgehäuse 10 verankerten Tragstangen 46 versetzt zu einer durch die beiden Achsen 35 und 39 verlaufenden Ebene angeordnet sind, so daß der abgezogene Elastomerfaden 37 die Antriebswalze 38 nicht berührt. Der Elastomerfaden 37 ist außerdem über eine an einem Schwenkhebel 47 gelagerte Rolle 48 geführt. Der Schwenkhebel 47 ist der Fühler einer im Innern des Vorrichtungsgehäuses 10 angeordneten Fadenbruch-Überwachungseinrichtung bekannter Art, zu welcher auch der mit einem Normalfaden 24 zusammenwirkende Schwenkhebel 49 als Fühler gehört. Beide Fühler 47 und 49 sind im Vorrichtungsgehäuse 10 verschwenkbar gelagert.The drive roller 38 can be formed in one piece with the storage drum 12, but can advantageously also be detachably connected to the storage drum 12 in a manner not shown here, for example by means of a screw connection or a bayonet-type rotary plug connection. The elastomer thread 37 is not guided over the storage drum 12, like a normal thread 24, but drawn off over two guide rollers 44 and 45, which are arranged on support rods 46 anchored on the device housing 10 to a plane running through the two axes 35 and 39, so that the stripped elastomer thread 37 does not touch the drive roller 38. The elastomer thread 37 is also guided over a roller 48 mounted on a pivot lever 47. The swivel lever 47 is the sensor of a known type of thread breakage monitoring device arranged inside the device housing 10, to which the swivel lever 49 cooperating with a normal thread 24 also belongs as a sensor. Both sensors 47 and 49 are pivotally mounted in the device housing 10.

Der Trägerteil für die Aufsteckspule 34 kann auch anders angeordnet sein. Beispielsweise könnte die Stange 31 auch unterhalb des Garnspulenträgers 34 schräg nach oben verstellbar angeordnet sein. Der Winkel a muß nicht 45° betragen, sondern kann auch einen anderen Spitzwinkelwert haben. Die Achsen 35 und 39 müssen auch nicht parallel verlaufen und sie müssen auch nicht in einer gemeinsamen Ebene liegen. Es können also beispielsweise auch konische Garnspulen eingesetzt werden.The carrier part for the plug-on coil 34 can also be arranged differently. For example, the rod 31 could also be arranged so as to be adjustable obliquely upwards below the spool carrier 34. The angle a does not have to be 45 °, but can also have a different acute angle value. The axes 35 and 39 also do not have to run parallel and they do not have to lie in a common plane. For example, conical spools of thread can also be used.

Die Vorrichtung kann auch ohne die Fadenspeichertrommel 12 ausgebildet werden. In diesem Falle geht die Welle 16 unmittelbar in die Antriebswelle 38 über. In diesem Fall können dann auch die Fadenleitorgane 19, 20, 21, der Knotenwächter 27 und der Fühler 49 entfallen.The device can also be designed without the thread storage drum 12. In this case, the shaft 16 merges directly into the drive shaft 38. In this case, the thread guide members 19, 20, 21, the knot monitor 27 and the sensor 49 can also be omitted.
