Description

Die Erfindung betrifft ein Verfahren zum Transport eines Spulenpaketes aus mindestens zwei Garnspulen zu einer Zwirnmaschine, mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1 sowie einen Spulentransportadapter mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 4.The invention relates to a method for transporting a package of bobbins from at least two yarn packages to a twisting machine, with the features from the preamble of claim 1 and a bobbin transport adapter with the features from the preamble of claim 4.

Beim Transport von Garnspulen zu garnerzeugenden oder garnverarbeitenden Maschinen muß der Anordnung und Lage der Fadenenden der Garnspulen große Aufmerksamkeit zugewendet werden. Dies ist einerseits für die Weiterbebehandlung der Garnspulen an der nächsten Arbeitsstelle notwendig, aber auch aus Sicherheitsgründen, da abfallende Fadenenden eine Transportautomation unter Umständen stark behindern.When transporting bobbins to yarn-producing or yarn-processing machines, great care must be taken with the arrangement and position of the thread ends of the bobbins. On the one hand, this is necessary for further processing of the bobbins at the next work station, but also for safety reasons, since falling thread ends may greatly hinder transport automation.

Es sind ein Verfahren und eine Vorrichtung zum Transportieren von Fadenlieferspulen bekannt (DE 38 11 667 A1) bei dem zum Transport zwei Garnspulen auf einen gemeinsamen hohlen Spulentransportadapter aufgesteckt werden, der an seinem oberen Ende einen Greifkopf zum Ansetzen eines Spulengreifers aufweist. Vor dem Transport werden die Fadenenden der Garnspulen in mehreren Windungen auf einen Teil der äußeren Oberfläche des Spulentransportadapters aufgewickelt.A method and a device for transporting thread delivery bobbins are known (DE 38 11 667 A1) in which two yarn bobbins are attached to a common hollow bobbin transport adapter which has a gripping head at its upper end for attaching a bobbin gripper. Before the transport, the thread ends of the bobbins are wound in several turns on a part of the outer surface of the bobbin transport adapter.

Es ist weiterhin bekannt beim Transport einzelner Garnspulen, beispielsweise Spinnspulen, das am äußeren Umfang der Spule liegende Fadenende zu suchen und vor dem Transportvorgang im Inneren des Spulenkernes anzuordnen (DE 32 35 442 A1 und DE 37 42 348 A1). Bei Zwirnmaschinen werden jeder Zwirnstelle oft mehrere einfachbewickelte Spulen zugeführt, wobei dann bei jeder einzelnen Spule auf die Lage der Fadenenden geachtet werden muß.It is also known when transporting individual bobbins of thread, for example spinning bobbins, to search for the thread end lying on the outer circumference of the bobbin and to arrange it in the interior of the bobbin core before the transport process (DE 32 35 442 A1 and DE 37 42 348 A1). In the case of twisting machines, several single-wound bobbins are often fed to each twisting point, in which case the position of the thread ends must be taken into account for each individual bobbin.

Es ist auch ein Spulentransportadapter bekannt (GB-A-1131699) bei dem die Fadenenden der Garnspulen am oberen Ende des Spulentransportadapters durch einen elastischen Klemmring festgehalten werden.A bobbin transport adapter is also known (GB-A-1131699) in which the thread ends of the bobbins are held in place at the upper end of the bobbin transport adapter by an elastic clamping ring.

Es ist auch bekannt, mehrere einer Zwirnmaschine zuzuführende Garnspulen zu einem Spulenpaket zuammenzufassen, wobei die Garnspulen mittels einer an sich bekannten Clips-Verbindung miteinander verbunden werden.It is also known to combine a plurality of yarn packages to be fed to a twisting machine to form a package of packages, the yarn packages being connected to one another by means of a clip connection known per se.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Transport eines Spulenpaketes aus mindestens zwei Garnspulen zu einer Zwirnmaschine der eingangs und im Oberbegriff des Patentanspruchs 1 angegebenen Art zu schaffen, bei dem die Fadenenden aller Garnspulen des Spulenpaketes in allen Stadien des Transports eine definierte fixierte Lage einnehmen, damit einerseits während des Transportvorgangs keine Fadenenden abfallen und andererseits am Ende des Transportvorgangs alle Fadenenden gemeinsam automatisch erfaßt werden können und somit eine funktionsgerechte Vorlage der Fadenenden für den weiteren Arbeitsvorgang möglich ist. Weiterhin sollte verhindert werden, daß durch die fixierte Lage der Fadenenden die Anwendung eines auf das Kopfstück des Spulentransportadapters aufzusteckenden Ablaufkopfes gestört wird.The invention has for its object to provide a method for transporting a package of at least two bobbins to a twisting machine of the type mentioned in the preamble of claim 1, in which the thread ends of all bobbins of the package in all stages of transport a defined fixed position take so that on the one hand no thread ends fall off during the transport process and on the other hand at the end of the transport process all thread ends can be automatically detected together and thus a functional presentation of the thread ends for the further work process is possible. Furthermore, it should be prevented that the fixed position of the thread ends disrupts the use of a drain head to be plugged onto the head piece of the bobbin transport adapter.

Weiterhin sollte ein Spulentransportadapter zur Durchführung dieses Verfahrens geschaffen werden.Furthermore, a coil transport adapter should be created to carry out this method.

Die Lösung dieser Aufgabe geschieht erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1. Vorteilhafte Weiterbildungen des erfingunsgemäßen Verfahrens sind Gegenstand der Patentansprüche 2 und 3.This object is achieved according to the invention with the features from the characterizing part of patent claim 1. Advantageous further developments of the method according to the invention are the subject of patent claims 2 and 3.

Patentanspruch 4 beschreibt und beansprucht einen Spulentransportadapter zur Durchführung des erfindungsgemäßen Verfahrens. Die Patentansprüche 5 bis 8 beschreiben vorteilhafte Weiterbildungen der Einrichtung nach Patentanspruch 4.Claim 4 describes and claims a coil transport adapter for performing the method according to the invention. Claims 5 to 8 describe advantageous developments of the device according to claim 4.

Der Grundgedanke des erfindungsgemäßen Verfahrens geht davon aus, in bekannter Weise die Garnspulen des Spulenpaketes über einen Spulentransportadapter miteinander zu verbinden. Dabei ist der Spulentransportadapter so ausgebildet, daß er nach Beendigung des Transportvorganges nicht aus dem Spulenpaket entfernt wird, sondern die Garnspulen des Spulenpaketes auch während des Verarbeitungsvorganges miteinander verbindet. Diese Vorgehensweise eröffnet die Möglichkeit, die Fadenenden aller Garnspulen des Spulenpaketes einmal vor dem Transportvorgang im Inneren des Spulentransportadapters anzuordnen und sie dort bis zum Einsetzen des Spulenpaketes in die Spindel der Zwirnmaschine festzuhalten. Auf diese Weise ist es möglich, daß unabhängig von den einzelnen Stationen des Transportvorgangs und der Art des verwendeten Transportsystems, die Fadenenden der Garnspulen gemeinsame ihre definierte Lage nicht verändern.The basic idea of the method according to the invention is based, in a known manner, on the yarn packages To connect the coil package to one another using a coil transport adapter. The bobbin transport adapter is designed such that it is not removed from the package of bobbins after the transport process has ended, but rather connects the bobbins of the package of bobbins to one another even during the processing process. This procedure opens up the possibility of arranging the thread ends of all the bobbins of the bobbin package once before the transport process inside the bobbin transport adapter and holding them there until the bobbin package is inserted into the spindle of the twisting machine. In this way, it is possible that regardless of the individual stations of the transport process and the type of transport system used, the thread ends of the yarn packages do not change their defined position together.

Im folgenden werden anhand der beigefügten Zeichnungen Ausführungsformen des erfindungsgemäßen Verfahrens sowie Einrichtungen zur Durchführung des Verfahrens näher erläutert.Embodiments of the method according to the invention and devices for carrying out the method are explained in more detail below with reference to the accompanying drawings.

At the upper end, the coil transport adapter 2 has a head piece 2.1, which is provided on its outer circumference with a hat 2.11 for attacking a coil gripper described below. Furthermore, the head piece 2.1 has on its inside below the upper edge an inward projection 2.12 for attaching the coupling element of a overhead conveyor described below.

Wie aus Fig. 1 ersichtlich, ist des aus den beiden Spulen 1.1 und 1.2 bestehende Spulenpaket 1 zusammen mit dem Spulentransportadapter 2 auf den Hohldorn 3.2 einer Vorbereitungseinrichtung 3 aufgesetzt. Der Hohldorn 3.2 ist im Grundgestell 3.1 der Vorbereitungseinrichtung 3 drehbar gelagert und über einen Rundschnurantrieb 3.3 antreibbar. An sein unteres Ende ist eine Saugdüse 3.4 ansetzbar. In der Vorbereitungsstation 3 werden die Fadenenden F1 und F2 mittels einer Bürste 3.5 abgebürstet, von einer Saugeinrichtung 3.6 erfaßt und über das obere Ende des Kopfstücks 2.1 geführt. Durch die Wirkung der unten an den Hohldorn 3.2 angesetzten Saugdüse 3.6 werden die Fadenenden dann, wie in Fig. 1 dargestellt, in den Innenraum des Spulentransportadapters 2 eingesaugt, wo sie während des ganzen nachfolgend beschriebenen Transportvorganges verbleiben.As can be seen from FIG. 1, the coil package 1 consisting of the two coils 1.1 and 1.2 is placed together with the coil transport adapter 2 on the hollow mandrel 3.2 of a preparation device 3. The hollow mandrel 3.2 is in the base frame 3.1 of the preparation device 3 rotatably supported and driven by a round cord drive 3.3. A suction nozzle 3.4 can be attached to its lower end. In the preparation station 3, the thread ends F1 and F2 are brushed using a brush 3.5, gripped by a suction device 3.6 and guided over the upper end of the head piece 2.1. Due to the action of the suction nozzle 3.6 attached to the hollow mandrel 3.2 below, the thread ends are then, as shown in FIG. 1, sucked into the interior of the bobbin transport adapter 2, where they remain during the entire transport process described below.

In Fig. 2 ist der Abnahmevorgang des Spulenpaketes 1 vom Hohldorn 3.2 der Vorbereitungseinrichtung 3 mittels eines Spulengreifers 4 dargestellt. Dabei greift die zangenartige Greifvorrichtung 4.1 des Spulengreifers 4 in die Nut 2.11 am Spulentransportadapter 2 ein. Gehalten vom Spulengreifer 4 wird das Spulenpaket 1 dann, wie in in Fig. 3 dargestellt, in einen Spulenhänger 5.2 eingehängt, der Teil eines Hängefördersystems 5 ist. Der Spulenhänger 5.2 besitzt an seinem unteren Ende ein Koppelelement 5.5, das hinter den Vorsprung 2.12 im Kopfstück 2.1 das Spulentransportadapters 2 einrastet. Die über den oberen Rand des Kopfstückes 2.1 laufenden Fadenenden F1 und F2 werden durch den am Spulenhänger 5.2 ungeordneten Konus 5.4 zusätzlich so Kopfstück 2.1 festgeklemmt. Der Spulenhänger 5.2 ist über Rollen 5.3 in einer Transportschiene 5.1 des Transportsystems 5 geführt.2 shows the removal process of the coil package 1 from the hollow mandrel 3.2 of the preparation device 3 by means of a coil gripper 4. The pincer-like gripping device 4.1 of the coil gripper 4 engages in the groove 2.11 on the coil transport adapter 2. Held by the coil gripper 4, the coil package 1 is then, as shown in FIG. 3, suspended in a coil hanger 5.2, which is part of an overhead conveyor system 5. At its lower end, the coil hanger 5.2 has a coupling element 5.5, which engages the coil transport adapter 2 behind the projection 2.12 in the head piece 2.1. The thread ends F1 and F2 running over the upper edge of the head piece 2.1 are additionally clamped by the cone 5.4 which is disordered on the bobbin hanger 5.2. The coil hanger 5.2 is guided over rollers 5.3 in a transport rail 5.1 of the transport system 5.

Nach dem Einhängen des Spulenpaketes 1 in den Spulenhänger 5.2 wird der Spulengreifer 4 vom Spulentransportadapter 2 abgelöst.After hanging the coil package 1 in the coil hanger 5.2, the coil gripper 4 is Coil transport adapter 2 detached.

Fig. 4 zeigt einerseits ein Schienenteil 5.1 des Transportsystems 5 mit dem daran laufenden, bereits leeren, Spulenhänger 5.2, von dem das Spulenpaket 1 mittels des Spulengreifers 4 abgenommen wurde. Weiterhin ist ein zweites Spulenpaket 1′ an einem Spulenhänger 5.2′ hängend zu sehen.Fig. 4 shows on the one hand a rail part 5.1 of the transport system 5 with the running, already empty, coil hanger 5.2, from which the coil package 1 was removed by means of the coil gripper 4. Furthermore, a second coil package 1 'on a coil hanger 5.2' can be seen hanging.

Mittels des mit seiner Greifvorrichtung 4.1 am Kopfstück 2.1 angreifenden Spulengreifers 4, wird das vom Spulenhänger 5.2 abgenommene Spulenpaket 1 in eine DoppeldrahtZwirnspindel 6 eingesetzt.By means of the bobbin gripper 4 acting on the head piece 2.1 with its gripping device 4.1, the bobbin 1 removed from the bobbin hanger 5.2 is inserted into a double-wire twist spindle 6.

In bekannter Weise besitzt die Doppeldraht-Zwirnspindel einen Wirtel 6.1, einen Drehteller 6.2 mit einer Fadenspeicherscheibe, einen Schutztopf 6.5 mit einem Boden 6.4, in dem axial der Hohldorn 6.3 angeordnet ist, auf den der Spulentransportadapter 2 mit dem Spulenpaket 1 aufgesteckt wird. Im Hohldorn 6.3 ist in nicht eigens dargestellter Weise ein Injektor angeordnet, durch den die Fadenenden F1 und F2 in das Innere der Spindel eingesaugt werden. Nach dem Einsetzen wird der Spulengreifer 4 vom Transportadapter 2 abgelöst.In a known manner, the double-wire twisting spindle has a whorl 6.1, a turntable 6.2 with a thread storage disk, a protective pot 6.5 with a bottom 6.4, in which the hollow mandrel 6.3 is arranged axially, onto which the bobbin transport adapter 2 with the bobbin packet 1 is attached. An injector, through which the thread ends F1 and F2 are sucked into the interior of the spindle, is arranged in the hollow mandrel 6.3 in a manner not specifically shown. After insertion, the coil gripper 4 is detached from the transport adapter 2.

Anhand von Fig. 5 wird im folgenden dargestellt, wie der Transportvorgang des Spulenpaketes 1 bei einer etwas anderen Ausführungsform eines Transportsystems von einer Vorbereitungsstation durchgeführt wird.5, it is shown below how the transport operation of the coil package 1 is carried out by a preparation station in a somewhat different embodiment of a transport system.

Es handelt sich hier um einen Transportsystem 7 mit Laufschienen 7.1, auf denen mit einem Hohldorn 7.2 auf der Oberseite versehene Transportteller 7.3 geführt sind. Zur Weiterförderung auf den Schienen 7.1 werden die Transportteller 7.3 an ihrer Unterseite mittels eines Rundschnurantriebes 7.4 angetrieben. Das Transportsystem 7 hat gegenüber einem Hängeförderer den Vorteil, daß es teilungsgebunden in einen Transportstrom eingefügt werden kann. Das Transportsystem läßt auch sehr einfache Weichenkonstruktionen zu, so daß die Transportströme sehr schnell umgeleitet werden können, z. B. in Wiederholvorgängen oder in Wartepositionen.This is a transport system 7 with running rails 7.1, on which transport plates 7.3 provided with a hollow mandrel 7.2 on the top are led. For further conveyance on the rails 7.1, the transport plates 7.3 are driven on their underside by means of a round cord drive 7.4. The transport system 7 has the advantage over a suspended conveyor that it can be inserted into a transport stream on a division basis. The transport system also allows very simple switch constructions, so that the transport streams can be diverted very quickly, e.g. B. in repetitions or in waiting positions.

Zum Transport des Spulenpaketes 1 wird der Spulentransportadapter 2 auf den Hohldorn 7.2 eines Transporttellers 7.3 aufgesteckt. Der auf dem Schienensystem 7.1 laufende Transportteller läuft in eine Vorbereitungseinrichtung 8 ein. Die Vorbereitungseinrichtung 8 besitzt eine Vorrichtung 8.1 mittels der der Transportteller 7.3 leicht angehoben wird und sich somit vom Rundschnurantrieb 7.4 löst. Gegen die äußeren Mantelfläche des Transporttellers 7.3 wird ein Reibradantrieb 8.3 angelegt, der den Transportteller 7.3 in Drehung versetzt. Mittels einer Bürste 8.5 und einer Ansaugvorrichtung 8.6 werden die Fadenenden F1 und F2 erfaßt und über das obere Ende des Kopfstückes 2.1 des Spulentransportadapters 2 geführt. An das untere Ende des Hohldorns 7.2 im Transportteller 7.3 wird eine gegenüber der Vorrichtung 8.1 drehbar gelagerte Saugdüse 8.4 angesetzt und mittels des Luftstroms die Fadenenden F1 und F2, wie in Fig. 5 dargestellt, in das Innere des Spulentransportadapters 2 eingeführt, wo sie während des gesamten Transportvorganges festgehalten sind.To transport the coil package 1, the coil transport adapter 2 is plugged onto the hollow mandrel 7.2 of a transport plate 7.3. The transport plate running on the rail system 7.1 runs into a preparation device 8. The preparation device 8 has a device 8.1 by means of which the transport plate 7.3 is raised slightly and thus detaches from the round cord drive 7.4. A friction wheel drive 8.3 is placed against the outer surface of the transport plate 7.3, which rotates the transport plate 7.3. The thread ends F1 and F2 are grasped by means of a brush 8.5 and a suction device 8.6 and guided over the upper end of the head piece 2.1 of the bobbin transport adapter 2. At the lower end of the hollow mandrel 7.2 in the transport plate 7.3, a suction nozzle 8.4 which is rotatably mounted relative to the device 8.1 is attached and by means of the air flow the thread ends F1 and F2, as shown in FIG. 5, are introduced into the interior of the bobbin transport adapter 2, where they are held during the entire transport process are recorded.

Die Abnahme des Spulenpaketes 1 vom Transportteller 7.3 und das Einsetzen in eine Doppeldraht-Zwirnspindel 6 kann dann, wie anhand von Fig. 4 beschrieben, mittels eines Spulengreifers 4 erfolgen.The bobbin packet 1 can then be removed from the transport plate 7.3 and inserted into a double-wire twisting spindle 6, as described with reference to FIG. 4, by means of a bobbin gripper 4.

Anhand der Fig. 6 bis 12 wird im folgenden beschrieben, daß es vorteilhaft sein kann, den Spulentransportadapter so auszubilden, daß die Fadenenden nicht über den oberen Rand des Kopfstückes in das Innere des Spulentransportadapters eingeführt werden. Derartige Spulentransportadapter haben den Vorteil, daß Fadenablaufhilfen oder Avivireinrichtungen, die als zusätzlicher Adapterkopf auf das Kopfstück des Spulentransportadapters aufgesteckt werden müssen, durch die in der zentralen Bohrung des Spulentransportadapters einlagernden Fadenenden nicht gestört werden. Bei dem Spulentransportadapter nach Fig. 1 bis 5 müssen vor den Einfügen eines zusätzlichen Adapterkopfes, z. B. für den besseren Fadeneinlauf, die Fadenenden aus der zentralen Bohrung durch eine Handhabungseinrichtung, einen Greifer, erst entnommen werden, bevor man einen derartigen Adapterkopf aufsetzen kann.6 to 12 it is described below that it may be advantageous to design the bobbin transport adapter so that the thread ends are not inserted into the interior of the bobbin transport adapter via the upper edge of the head piece. Such bobbin transport adapters have the advantage that thread drain aids or avivir devices, which have to be plugged onto the head piece of the bobbin transport adapter as an additional adapter head, are not disturbed by the thread ends embedded in the central bore of the bobbin transport adapter. 1 to 5 must be before inserting an additional adapter head, for. B. for better thread entry, the thread ends from the central bore through a handling device, a gripper, can only be removed before you can attach such an adapter head.

Furthermore, on the inside, as also described, the head piece has an inwardly projecting projection 12.12 for attaching the coupling element of a overhead conveyor.

Die Fadenenden F1 und F2 werden bei dieser Ausführungsform des Spulentransportadapters nicht über den oberen Rand des Kopfstückes 12.1 in den Innenraum des rohrförmigen Spulentransportadapters eingeführt, sondern sie gelangen durch eine Einführungsöffnung 12.3 in der äußeren Mantelfläche des Kopfstücks 12.1 in einen, in Umfangsrichtung im Kopfstück über einen Winkel von ca. 270o geführten Fadenaufnahmekanal 12.4, dessen eines Ende mit der Einführungsöffnung 12.3 und dessen anderes Ende mit einer zweiten Öffnung 12.5 verbunden ist, an die eine Saugdüse 9 ansetzbar ist. Die Fadenenden F1 und F2 befinden sich während des ganzen Transportvorganges in diesem Fadenaufnahmekanal 12.4.In this embodiment of the bobbin transport adapter, the thread ends F1 and F2 are not introduced into the interior of the tubular bobbin transport adapter via the upper edge of the head piece 12.1, but instead pass through an insertion opening 12.3 in the outer lateral surface of the head piece 12.1 into one, in the circumferential direction in the head piece via one angle of about 270 to which a suction nozzle 9 can be attached o-run thread-receiving channel 12.4, having one end connected to the introduction opening 12.3 and the other end is connected to a second opening 12.5. The thread ends F1 and F2 are in this thread take-up channel 12.4 during the entire transport process.

Nach dem Einsetzen in die Doppeldraht-Zwirnspindel 6′ wird auf den Transportadapter 12 ein Ablaufkopf 10 aufgesetzt, eine Greifvorrichtung 13 nimmt die Fig. 7 in gestrichelter Position eingezeichneten Fadenenden auf und führt sie dem oberen Ende des Ablaufkopfes 10 zu. Dort werden sie mittels des durch den Injektor verursachten Luftstroms durch den Ablaufkopf 10 und den Transportadapter 12 hindurch unmittelbar in die Spindel eingeführt. Bei einer weiteren in Fig. 10 dargestellten Ausführungsform, eines das Spulenpaket 1 verbindenden Spulentransportadapters 12′, werden die Fadenenden durch eine Eintrittsöffnung 12.3′ und einen Fadenaufnahmekanal 12.4′ in einen Raum zwischen dem äußeren Rohr des Spulentransportadapters 12′ und einer Innenhülse 12.6′ eingesaugt. Die Innenhülse 12.6′ sitzt nach dem Einsetzen in die Doppeldraht-Zwirnspindel über eine elastische Manschette 12.7′ auf dem Hohldorn 6.3′ der Doppeldraht-Zwirnspindel auf. Die Manschette 12.7′ dient der Abdichtung des Innenraums des Spulentransportadapters, wenn der Faden in der Doppeldraht-Zwirnspindel mit Luft durchgefädelt wird. Dabei muß sichergestellt werden, daß Fremdlufteinflüsse den Vorgang nicht stören.After insertion into the double-wire twisting spindle 6 ', a discharge head 10 is placed on the transport adapter 12, a gripping device 13 takes the thread ends shown in FIG. 7 in a broken line position and leads them to the upper end of the discharge head 10.
