Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1. Es handelt sich dabei insbesondere um eine Vorrichtung, um voll gewickelte, beispielsweise von einem Spulautomaten erzeugte Spulen aufzunehmen und an eine Spulentransporteinrichtung zu übergeben, von der diese Spulen je nach dem späteren Verwendungszweck einer weiterverarbeitenden Maschine, beispielsweise Doppeldraht-Zwirnmaschine, zugeführt werden.The invention relates to a device according to the preamble of claim 1. It is, in particular, a device to take up fully wound bobbins, for example those produced by an automatic winder, and to transfer them to a bobbin transport device, from which these bobbins, depending on the later use, of a further processing unit Machine, for example double wire twisting machine, are supplied.

In der DE-A-3 303 733 ist eine Spulenumsetzvorrichtung beschrieben, die einen entlang von Querschienen verfahrbaren Wagen aufweist, der einen vertikalen Ständer für eine entlang des Ständers auf- und abbewegbare und um die vertikale Ständerachse drehbare Schiebehülse trägt. An dieser Schiebehülse ist eine Horizontalschiene befestigt, entlang welcher ein Schieber verschiebbar ist, der gleichzeitig als Kulisse für eine quer zur ersten Schiene verschiebbare Tragstange bildet, die ein Aufnahmeelement für eine Garnspule trägt. Diese bekannte Umsetzstation ist in der Lage, horizontal ausgerichtete Garnspulen aufzunehmen und diese ausschließlich wieder in horizontal ausgerichteter Lage an eine weitere Fördereinrichtung zu übergeben.DE-A-3 303 733 describes a coil transfer device which has a carriage which can be moved along transverse rails and which carries a vertical stand for a sliding sleeve which can be moved up and down along the stand and rotatable about the vertical stand axis. A horizontal rail is fastened to this sliding sleeve, along which a slide can be displaced, which at the same time forms a backdrop for a support rod which can be displaced transversely to the first rail and carries a receiving element for a yarn spool. This known transfer station is able to take up horizontally aligned spools of thread and to transfer them back to a further conveyor only in the horizontally aligned position.

In der DE-A-3 824 874 ist eine Spulenumsetzstation beschrieben, mit der horizontal ausgerichtete Garnspulen umgewendet und mit horizontal ausgerichteten Achsen auch auf einem Förderband abgelegt werden. Eine Hängefördereinrichtung ist mit Spulenaufnehmern versehen, die an Hubeinrichtungen befestigt sind, um die Spulenaufnehmer nach unten absenken und damit die vorher auf dem Förderband abgestellten Spulen übernehmen zu können. Bei dieser Vorrichtung kann der Spulentransport jeweils nur in einer Richtung erfolgen, d.h. es besteht nicht die Möglichkeit, im Bereich der beispielsweise einer weiterverarbeitenden Maschine freigewordene, d.h. leere Spulenadapter aufzunehmen und anschließend wieder mit voll bewikkelten Spulen zu bestücken.DE-A-3 824 874 describes a bobbin transfer station with which horizontally aligned bobbins are turned over and are also placed on a conveyor belt with horizontally aligned axes. A overhead conveyor is provided with spool receptacles, which are attached to lifting devices in order to lower the spool receptacles and thus to be able to take over the spools previously placed on the conveyor belt. With this device, the spool can only be transported in one direction, i.e. it is not possible to remove, e.g. Pick up empty bobbin adapters and then fill them with fully wound bobbins.

Eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1 ist in der EP 00 26 160 beschrieben. Diese bekannte Vorrichtung dient dazu, jeweils zwei axial ausgerichtete hintereinander liegende Einzelspulen mittels des Spulenadapters zu einer Spulengruppe zusammenzufassen, die man anschließend unter dem Einfluß der Schwerkraft in einen Speicher oder einen Sammelwagen fallen läßt. Die einzelnen Spulenadapter werden vorher aus einem Spulenmagazin entnommen. Für die Weiterverarbeitung müssen die in dem Speicher oder Sammelwagen abgelegten Spuleneinheiten erneut wieder erfaßt werden, wobei sich für die schonende Entnahme dieser Spuleneinheiten Praktisch nur eine Entnahme per Hand eignet.A device according to the preamble of claim 1 is described in EP 00 26 160. This known device is used to combine two axially aligned individual coils one behind the other by means of the coil adapter to form a coil group, which is then dropped under the influence of gravity into a storage device or a collecting trolley. The individual coil adapters are previously removed from a coil magazine. For further processing, the coil units stored in the storage or collecting trolley must be recorded again, with practically only manual removal being suitable for the gentle removal of these coil units.

Die DE-OS 38 02 900 behandelt eine Spulen- übergabebzw. Spulenumsetzvorrichtung zum Verbinden eines Spulautomaten mit einer Doppeldraht-Zwirnmaschine. Es handelt sich dabei insbesondere um eine Vorrichtung, bei der Spulen mittels eines Greifers von einem Förderband abgenommen und nach Veränderung der Achslage der Spulen auf Spulenträger eines um eine Doppeldraht-Zwirnmaschine umlaufenden Förderbandes abgegeben werden.DE-OS 38 02 900 deals with a coil transfer or. Bobbin transfer device for connecting an automatic winder to a double-wire twisting machine. It is in particular a device in which bobbins are removed from a conveyor belt by means of a gripper and, after changing the axial position of the bobbins, are delivered to bobbin carriers of a conveyor belt rotating around a double-wire twisting machine.

Im Gegensatz dazu wird durch die Lösung gemäß dem Kennzeichen des Patentanspruchs 1 die Möglichkeit geschaffen, beispielsweise von einem Spulautomaten Kommende, horizontal ausgerichtete Spulen so mittels eines Spulenadapters zu erfassen und weiterzufördern, daß sie als eine Einheit mit dem Spulenadapter zusammengefaßt vertikal ausgerichtet an eine Hängefördereinrichtung übergeben und zu einer weiterverarbeitenden Maschine gefördert werden. Die Übergabebzw. Umsetzvorrichtung kennzeichnet sich dabei insbesondere auch dadurch aus, daß im Bereich der weiterverarbeitenden Maschine freigewordene Spulenadapter erneut zur Bestückung mit Einzelspulen oder Spulengruppen benutzt werden können, indem nämlich diese freigewordenen bzw. leeren Spulenadapter mittels der Hängefördereinrichtung, die vorher die aus Spulen und Adaptern zusammengefaßten Einheiten in den Bereich der weiterverarbeitenden Maschine gefördert hat, wieder in den Bereich der an dem Drehkopf befestigten Hubzylindereinheit zurückgefördert werden.In contrast to this, the solution according to the characterizing part of patent claim 1 creates the possibility, for example, of detecting and conveying horizontally aligned coils coming from an automatic winder by means of a coil adapter such that they are passed together as a unit with the coil adapter and aligned vertically to a hanging conveyor and be promoted to a processing machine. The transfer or Conversion device is characterized in particular by the fact that in the area of the further processing machine, the reel adapters that have become free can be used again for equipping with individual coils or groups of coils, namely by means of the overhead conveyor device that freed or empty reel adapters that previously contained the units composed of coils and adapters has promoted the area of the further processing machine, be conveyed back into the area of the lifting cylinder unit attached to the rotary head.

Die erfindungsgemäße Lösung besteht somit im wesentlichen darin, der Spulenübergabe- bzw. Spulenumsetzstation eine solche Spulentransporteinrichtung zuzuordnen, daß von der weiterverarbeitenden Maschine zurückkehrende leere Spulenadapter aufgenommen werden, anschließend mit voll gewickelten Spulen bestückt und dann als aus Einzelspulen bzw. Spulengruppen und Spulenadaptern bestehenden Einheiten wieder an die Spulentransporteinrichtung übergeben und in den Bereich der weiterverarbeitenden Maschine gefördert werden.The solution according to the invention essentially consists in assigning the bobbin transfer or bobbin transfer station to a bobbin transport device such that empty bobbin adapters returning from the processing machine are picked up, then fitted with fully wound bobbins and then again as units consisting of individual bobbins or bobbin groups and bobbin adapters transferred to the bobbin transport device and conveyed to the area of the further processing machine.

Die Merkmale der Unteransprüche dienen dazu, im Bereich der eigentlichen Übergabe- bzw. Umsetzeinrichtung die aus Spulenadaptern und Einzelspulen oder Spulengruppen bestehenden Einheiten so vorzubereiten, daß sich automatisierte Handhabungsprozesse anschließen können.The features of the subclaims serve in the area of the actual transfer or conversion device to prepare the units consisting of coil adapters and individual coils or coil groups so that automated handling processes can follow.

Das erfindungsgemäße Arbeitsprinzip wird im folgenden anhand der Fig. 2 bis 4 beschrieben.The working principle according to the invention is described below with reference to FIGS. 2 to 4.

Die erfindungsgemäße Vorrichtung weist gemäß den Fig. 2 bis 4 drei Einzelaggregate auf, nämlich einen Spulenzuförderaggregat A, das Umsetzaggregat B und die Hängefördereinrichtung C.The device according to the invention has, according to FIGS. 2 to 4, three individual units, namely a coil feed unit A, the transfer unit B and the overhead conveyor device C.

Das Spulenzuförderaggregat A umfaßt als wesentliche Einzelteile ein Maschinengestell 30 mit einer Horizontalfördereinrichtung 31 zum Zuführen von Einzelspulen oder Spulengruppen 17, 17.1. Es sind weiterhin ein Bandförderer 32 und eine Hubeinrichtung 33 vorgesehen, deren ausfahrbares Hubelement 34 eine Spulenablage 35 trägt. Der Bandförderer 32, das ausfahrbare Hubelement 34 und die Spulenablage 35 sind so gestaltet, daß gemäß Fig. 4 auf dem Bandförderer 32 geförderte Spulen 17, 17.1 durch Hochfahren der Spulenablage 35 von dem Bandförderer 32 abgenommen und beispielsweise in eine Stellung gemäß den Fig. 2 und 3 hochgefahren werden können.The coil feed assembly A comprises as essential individual parts a machine frame 30 with a horizontal conveyor device 31 for feeding individual coils or coil groups 17, 17.1. A belt conveyor 32 and a lifting device 33 are also provided, the extendable lifting element 34 of which carries a bobbin holder 35. The belt conveyor 32, the extendable lifting element 34 and the spool holder 35 are designed such that, according to FIG. 4, spools 17, 17.1 conveyed on the belt conveyor 32 are removed from the belt conveyor 32 by raising the spool holder 35 and, for example, into a position according to FIG. 2 and 3 can be started.

Das Umsetzaggregat B enthält eine stationäre Säule 13, an der der Schlitten 14 auf- und abbewegt werden kann. Der Schlitten 14 trägt einen um eine horizontale Achse drehbaren Drehkopf 2, an dem eine Hubzylindereinheit 1 mit dem ein- und ausfahrbaren Hubelement 1.1 befestigt ist. Gemäß Fig. 1 ist an diesem ausfahrbaren Hubelement 1.1 ein Spulenadapter-Träger 7 befestigt, bestehend aus einem Anschlagteller 8 und einem Dorn 9.The transfer unit B contains a stationary column 13 on which the carriage 14 can be moved up and down. The carriage 14 carries a rotary head 2 which can be rotated about a horizontal axis and to which a lifting cylinder unit 1 is fastened with the lifting element 1.1 which can be moved in and out. According to FIG. 1, a coil adapter carrier 7 is attached to this extendable lifting element 1.1, consisting of a stop plate 8 and a mandrel 9.

Die als Hängefördereinrichtung C ausgebildete Spulentransporteinrichtung umfaßt eine Oberschiene 4, in der eine Förderkette oder ein Förderband geführt ist, an dem in gleichmäßigen Abständen Spulenhängehalter 5 befestigt sind.The coil transport device designed as a hanging conveyor device C comprises a top rail 4, in which a conveyor chain or a conveyor belt is guided, on which bobbin hanging holders 5 are fastened at regular intervals.

Anhand der beschriebenen Konstruktionselemente läßt sich das erfindungsgemäße Arbeitsprinzip wie folgt beschreiben:

  • Von dem Umsetzaggregat B werden der Schlitten 14 und zusätzlich das bewegliche Hubelement 1.1 so weit hochgefahren, daß der Dorn 9 in das untere Ende eines von einem Spulenhängehalter 5 getragenen Spulenadapters 6 eingefahren wird. Um den Spulenadapter 6 von dem Hängehalter 5 freizubekommen ist dieser in bekannter Weise so gestaltet, daß der Spulenadapter 6 nach ausreichendem Hochfahren relativ zu dem Hängehalter von diesem freigegeben wird.
Using the construction elements described, the working principle according to the invention can be described as follows:
  • From the transfer unit B, the carriage 14 and additionally the movable lifting element 1.1 are raised so far that the mandrel 9 is inserted into the lower end of a coil adapter 6 carried by a coil suspension holder 5. In order to get the bobbin adapter 6 free from the hanging holder 5, the latter is designed in a known manner in such a way that the bobbin adapter 6 is released by the hanging holder after it has been raised sufficiently.

Sobald der Spulenadapter 6 von dem Hängehalter 5 freigegeben ist, wird der Schlitten 14 in die in Fig. 3 dargestellte Stellung abgesenkt, bis die horizontale Drehachse des Drehkopfes 2 mit dem im wesentlichen horizontal ausgerichteten Spulenachsen der auf der Spulenablage 35 abgelegten Spulen 17, 17.1 die gleiche Höhenlage hat. Danach wird durch Betätigen des Drehkopfes 2 die Hubzylindereinheit 1 aus ihrer vertikal aufgerichteten Position in eine horizontal liegende Position verschwenkt, um durch Druckbeaufschlagung der Hubzylindereinheit 1 den Spulenadapter 6 in die Spulen 17, 17.1 einfahren zu können. Danach wird der Drehkopf wieder zurückgestellt, derart, daß die Hybzylindereinheit 1 wieder in ihre vertikale Ausgangsstellung einnimmt.

  • Diese Situation ist in Fig. 4 dargestellt, wobei aus Gründen der Vereinfachung der Abstand zwischen dem Spulen-Zuförderaggregat A und dem Umsetzaggregat B entgegen den tatsächlichen Verhältnissen kleiner dargestellt ist.
As soon as the coil adapter 6 is released from the hanging holder 5, the carriage 14 is lowered into the position shown in FIG. 3 until the horizontal axis of rotation of the rotary head 2 with the substantially horizontally aligned coil axes of the coils 17, 17.1 deposited on the coil holder 35 has the same altitude. Then, by actuating the rotary head 2, the lifting cylinder unit 1 is pivoted from its vertically erected position into a horizontally lying position in order to be able to retract the coil adapter 6 into the coils 17, 17.1 by pressurizing the lifting cylinder unit 1. The rotary head is then reset again in such a way that the hybrid cylinder unit 1 returns to its vertical starting position.
  • This situation is shown in FIG. 4, the distance between the coil feed unit A and the transfer unit B being shown to be smaller, contrary to the actual conditions, for reasons of simplification.

Sobald die Hubzylindereinheit 1 wieder in ihre vertikale Stellung zurückgestellt ist, kann die aus den beiden Spulen 17, 17.1 und dem Spulenadapter 6 bestehende Spuleneinheit D wieder durch Hochfahren des Schlittens 14 an den freien Spulen- hängehalter 5 übergeben werden.As soon as the lifting cylinder unit 1 is returned to its vertical position, the coil unit D consisting of the two coils 17, 17.1 and the coil adapter 6 can again be transferred to the free coil suspension holder 5 by raising the slide 14.

Danach wird der Schlitten 14 wieder so weit abgesenkt, daß das untere Ende des Spulenadapters 6 von dem Dorn 9 freigegeben ist, so daß die zuletzt abgegebene Spuleneinheit D um einen Schritt weiter gefördert werden kann. Dadurch kommt der nächstfolgende Spulenadapter in den Bereich des Umsetzaggregates B, so daß der beschriebene Arbeitszylkus erneut beginnen kann, nämlich Abnehmen des Spulenadapters 6 von dem Spulen-Hängehalter 5 usw..Thereafter, the carriage 14 is lowered again so far that the lower end of the coil adapter 6 is released from the mandrel 9, so that the coil unit D last released can be conveyed one step further. As a result, the next coil adapter comes into the area of the transfer unit B, so that the described working cycle can begin again, namely removal of the coil adapter 6 from the coil suspension holder 5, etc.

Es versteht sich von selbst, daß eine Spuleinheit D anstelle zwei Spulen 17, 17.1 und dem Spulenadapter 6 auch nur eine Spule 17 und einen Spulenadapter 6 umfassen kann.It goes without saying that instead of two coils 17, 17.1 and the coil adapter 6, a coil unit D can also comprise only one coil 17 and one coil adapter 6.

Um die Spuleneinheiten während des Umsetzens bzw. im Verlauf der Spulenübergabe für eine weitere automatisierte Handhabung vorzubereiten, sind weitere Einzelelemente vorgesehen.In order to prepare the coil units for further automated handling during the transfer or in the course of the coil transfer, further individual elements are provided.

Gemäß Fig. 1 ist der Dorn 9 mit einem vorzugsweise radial gerichteten Positionierstift 10 versehen, während der Spulenadapter 6 an seiner Innenseite mit schräg und/oder spiralförmig verlaufenden Führungsflächen 11 und einer nach unten offenen Einrastnut 12 versehen ist. Beim Einschieben des Domes 9 in den Adapter 6 wird durch Zusammenwirken der Führungsflächen 11 mit dem Positionierstift 10 der Spulenadapter in Richtung der Pfeile f1 bzw. f2 verdreht, bis der Positionierstift 10 in die Einrastnut 12 einrastet. Dadurch wird beim Einfahren des Domes 9 in den Spulenadapter 6 eine bestimmte Relativposition zwischen dem Spulenadapter 6 und dem Dorn 9 erreicht.1, the mandrel 9 is provided with a preferably radially directed positioning pin 10, while the coil adapter 6 is provided on its inside with oblique and / or spiral guide surfaces 11 and a downwardly open latching groove 12. When the dome 9 is inserted into the adapter 6, the coil adapter is rotated in the direction of the arrows f1 or f2 by the interaction of the guide surfaces 11 with the positioning pin 10 until the positioning pin 10 engages in the latching groove 12. As a result, a certain relative position between the coil adapter 6 and the mandrel 9 is achieved when the dome 9 is moved into the coil adapter 6.

An dem ausfahrbaren Hubelement 1.1 ist ein Drehantrieb 15 mit einer Scheibe 15.1 und einem über die Scheibe 15.1 gelegten Antriebsriemen 15.2 befestigt. Der Antriebsriemen 15.2 ist weiterhin um den Anschlagteller 8 des Spulenadapterträgers 7 gelegt, derart, daß mittels des Drehantriebes der Träger 7 z.B. zusammen mit der darauf befindlichen Spuleneinheit D in Drehung versetzt werden kann.A rotary drive 15 with a pulley 15.1 and a drive belt 15.2 placed over the pulley 15.1 is fastened to the extendable lifting element 1.1. The drive belt 15.2 is also placed around the stop plate 8 of the coil adapter carrier 7 in such a way that the carrier 7 e.g. can be rotated together with the coil unit D located thereon.

Diese Möglichkeit, den Träger bzw. die Spuleneinheit D in Drehung zu versetzen, hat den Zweck, nach Heranstellen einer Saugeinrichtung 16 an die Mantelflächen der Spulen 17, 17.1 die freien Fadenenden aufzufinden und in die Saugeinrichtung einzusaugen. Die Saugeinrichtung 16 kann eine oder mehrere Saugdüsen mit länglichen, vertikal ausgerichteten Düsenschlitzen aufweisen, die einzeln oder gemeinsam an die Spulen 17, 17.1 anstellbar sind. Nach Anstellen der Saugeinrichtung 16 an die Spuleneinheit D und nach Beaufschlagung der Saugeinrichtung mit Saugluft wird die Spuleneinheit D so lange in Drehung versetzt, bis nicht dargestellte, beispielsweise optische Tastelemente feststellen, daß die Fäden von beiden Spulen 17 und 17.1 in die Saugeinrichtung eingesaugt sind.This possibility of causing the carrier or the bobbin unit D to rotate has the purpose of locating the free thread ends after sucking up a suction device 16 on the lateral surfaces of the bobbins 17, 17.1 and sucking them into the suction device. The suction device 16 can have one or more suction nozzles with elongated, vertically oriented nozzle slots which can be adjusted individually or together on the coils 17, 17.1. After placing the suction device 16 on the bobbin unit D and after applying suction air to the bobbin unit D, the bobbin unit D is rotated until, for example, optical probes (not shown) determine that the threads of both bobbins 17 and 17.1 are sucked into the suction device.

Zusätzlich oder anstelle des Drehantriebs 15 verfügt der Drehkopf 2 über eine weitere Dreheinrichtung, deren Drehachse senkrecht zur horizontalen Drehachse des Drehkopfes 2 liegt. Diese weitere Dreheinrichtung dient bevorzugt zum Antrieb des Spulenadapter-Trägers 7.In addition to or instead of the rotary drive 15, the rotary head 2 has a further rotary device, the axis of rotation of which is perpendicular to the horizontal axis of rotation of the rotary head 2. This further rotating device is preferably used to drive the coil adapter carrier 7.

Ein in Fig. 5 dargestellter Fadenmitnehmer 18 ist so angeordnet, daß seine beispielsweise V-förmige Mitnahmekerbe 18.1 beim Hochfahren in Richtung des Pfeiles f3 die beiden infolge der Saugwirkung der Saugeinrichtung 16 noch unter Spannung stehenden Fäden F1 und F2 ergreift und nach oben zu einer Fadenklemme 19 fördert, die zum Ergreifen und Festklemmen der beiden Fäden entweder pneumatisch oder elektrisch betätigt werden kann.A thread driver 18 shown in FIG. 5 is arranged such that its V-shaped driving notch 18.1, for example, grips the two threads F1 and F2 which are still under tension as a result of the suction effect of the suction device 16 when it is raised in the direction of arrow f3 and upwards to a thread clamp 19 promotes that can be actuated either pneumatically or electrically to grasp and clamp the two threads.

Die Fadenklemme 19 ist mittels geeigneter Horizontal- und Vertikalträger und zugeordneter Stellorgane nach dem Ergreifen der beiden Fäden so an das obere Ende des Spulenadapters heranführbar, daß die beiden Fäden F1 und F2 vor eine am oberen Ende des Spulenadapters 6 befindliche Öffnung 20 geführt werden können.The thread clamp 19 can be brought up to the upper end of the bobbin adapter by means of suitable horizontal and vertical supports and associated actuators after gripping the two threads so that the two threads F1 and F2 can be guided in front of an opening 20 located at the upper end of the bobbin adapter 6.

Gemäß den Fig. 6 und 7 schließt sich an diese erste Öffnung 20 ein in Umfangsrichtung über einen vorgegebenen Umfangswinkel geführter Fadenleitkanal 21 an, der zu einer zweiten Öffnung 22 in der Mantelfläche des Spulenadapters 6 führt. In diese zweite Öffnung 22 ist das vordere Düsenende einer Saugdüse 23 einführbar, die mittels eines Hebegestänges 24 an einer Konsole 25 des Maschinengestells gelagert ist. An die Saugdüse 23 ist ein Saugschlauch 26 angeschlossen. Innerhalb der Saugdüse 23 ist eine Schneideeinrichtung 36 angebracht, um eingesaugte Fäden mit definierter Länge abzuschneiden.According to FIGS. 6 and 7, this first opening 20 is followed by a thread guide channel 21 which is guided in the circumferential direction over a predetermined circumferential angle and leads to a second opening 22 in the lateral surface of the bobbin adapter 6. The front nozzle end of a suction nozzle 23 can be inserted into this second opening 22 and is mounted on a bracket 25 of the machine frame by means of a lifting rod 24. A suction hose 26 is connected to the suction nozzle 23. A cutting device 36 is attached within the suction nozzle 23 in order to cut threads that have been sucked in with a defined length.

Wenn die beiden Fäden F1 und F2 von der Fadenklemme 19 an die Eintrittsöffnung 20 des Adapters herangeführt sind, und wenn nach Einfahren der Saugdüse 23 in die Öfnung 21 die Saugdüse mit Saugluft beaufschlagt wird, können nach Lösen der Fadenklemme 19 die beiden Fäden von der Saugluft in die Saugdüse 23 eingesaugt werden, und zwar im wesentlichen in Abhängigkeit von den Fadenlängen, die vorher in die Saugeinrichtung 16 eingesaugt worden sind.If the two threads F1 and F2 are brought from the thread clamp 19 to the inlet opening 20 of the adapter, and if the suction nozzle is acted upon by suction air after the suction nozzle 23 has been moved into the opening 21, the two threads can be released from the suction air after loosening the thread clamp 19 are sucked into the suction nozzle 23, essentially as a function of the thread lengths which have previously been sucked into the suction device 16.

Nach Abstellen der im Bereich der Saugdüse 23 wirksamen Saugluft wird die Saugdüse wieder von dem Spulenadapter 6 weggestellt, so daß dann die Enden der beiden Fäden F1 und F2 aus der Austrittsöffnung 21 mit definierten, gleichmäßigen Fadenlängen heraushängen.After switching off the suction air effective in the area of the suction nozzle 23, the suction nozzle is again put away from the bobbin adapter 6, so that the ends of the two threads F1 and F2 then hang out of the outlet opening 21 with defined, uniform thread lengths.

Dieses Einsaugen der Fäden F1 und F2 in die Öffnungen des Spulenadapters dienten dazu, die beiden Fadenenden für weitere automatische Handhabungsprozesse an einer bestimmten definierten Stelle zur Verfügung zu haben.This sucking in of the threads F1 and F2 into the openings of the bobbin adapter served to have the two thread ends available for further automatic handling processes at a certain defined point.

Aus dem Gesamtzusammenhang wird damit auch die Bedeutung sowohl des Positionieres des Adapters bezüglich seiner Winkelstellung relativ zum Spulenadapterträger 7 als auch die Bedeutung des Drehantriebes 5 ersichtlich, da es darum geht, die Öffnungen 20 bzw. 22 des Adapters in die notwendige Gegenüberstellung relativ zu der Fadenklemme 19 einerseits bzw. der Saugdüse 23 andererseits zu bringen bzw. das Auffinden der Fäden F1 und F2 durch die Saugeinrichtung 16 zu ermöglichen. Dabei ist davon ausgegangen, daß zum Suchen bzw. Auffinden der Fäden F1 und F2 durch die Saugeinrichtung 16 der Spulenadapter- träger 7 und damit die Spuleneinheit D jeweils immer zu ganzen vollen Umdrehungen angetrieben wird.From the overall context, the importance of both the positioning of the adapter with respect to its angular position relative to the bobbin adapter carrier 7 and the importance of the rotary drive 5 can also be seen, since the aim is to place the openings 20 and 22 of the adapter in the necessary juxtaposition relative to the thread clamp 19 on the one hand or the suction nozzle 23 on the other hand or to enable the threads F1 and F2 to be found by the suction device 16. It has been assumed that to search for or locate the threads F1 and F2 by the suction device 16, the bobbin adapter carrier 7 and thus the bobbin unit D are always driven to full revolutions becomes.
