Description

Die Erfindung betrifft eine Vorrichtung zum Anlegen mehrerer Fäden an rotierenden Galetten einer Schmelzspinnmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for applying several threads to rotating godets of a melt spinning machine according to the preamble of claim 1.

Eine gattungsgemäße Vorrichtung ist aus der DE 1 710 649 A1 bekannt.A generic device is from the DE 1 710 649 A1 known.

Bei der Herstellung von synthetischen Fäden werden diese zunächst aus einer Polymerschmelze in feinsten Filamentsträngen extrudiert. Nach einer Abkühlung und Bündelung der Filamente zu einem Faden wird dieser nachfolgend in Abhängigkeit vom Prozess in ein oder mehreren Stufen behandelt. So ist es bekannt, die Fäden nach dem Spinnen über rotierende Galetten zu führen, die mit einer Differenzgeschwindigkeit zum Verstrecken der Fäden betrieben werden. Ebenso können Verwirbelungen, Benetzungen oder Kräuselungen an den Fäden ausgeführt werden. In Abhängigkeit von dem jeweiligen Behandlungsschritt werden dabei die Fäden als eine Fadenschar oder separiert geführt. Unabhängig von der Art der Führung ist es bei jeder Schmelzspinnmaschine erforderlich, die Fäden nach dem Anspinnen an die Behandlungsaggregate insbesondere an die rotierenden Galetten anzulegen. Die bekannte Vorrichtung aus der DE 17 10 649 weist hierzu einen Handinjektor auf, der mit einer Schneideinrichtungen zusammenwirkt. So ist es möglich, ein oder auch mehrere Fäden wahlweise manuell mit dem Handinjektor zu führen und in die nachfolgenden Behandlungsaggregate anzulegen.In the production of synthetic threads, these are first extruded from a polymer melt in the finest filament strands. After the filaments have cooled and bundled to form a thread, this is subsequently treated in one or more stages depending on the process. Thus, it is known to guide the threads after spinning over rotating godets, which are operated at a differential speed to stretch the threads. Swirling, wetting or crimping on the threads can also be carried out. Depending on the respective treatment step, the threads are guided as a group of threads or separately. Regardless of the type of guidance, it is necessary with every melt spinning machine to apply the threads after spinning onto the treatment units, in particular onto the rotating godets. The known device from the DE 17 10 649 has a hand injector which interacts with a cutting device. It is thus possible to optionally guide one or more threads manually with the hand injector and put them into the subsequent treatment units.

Nun sind auch Schmelzspinnmaschinen bekannt, bei welcher die Fadenführung an den Behandlungsaggregaten in unterschiedlicher Art und Weise erfolgen. Bei derartigen Schmelzspinnmaschinen ist es erforderlich, dass die Fäden teilweise separat und teilweise als Fadenschar während des Anlegeprozesses geführt werden müssen.Now melt spinning machines are also known, in which the thread guidance on the treatment units takes place in different ways. In melt spinning machines of this type, it is necessary that the threads have to be guided partly separately and partly as a group of threads during the threading process.

Es ist daher Aufgabe der Erfindung, eine gattungsgemäße Vorrichtung zum Anlegen mehrerer Fäden an rotierenden Galetten einer Schmelzspinnmaschine derart weiterzubilden, dass unabhängig von der Prozessführung eine flexible und bedienungsfreundliche Handhabung für einen Operator gewährleistet ist.It is therefore an object of the invention to develop a generic device for applying a plurality of threads to rotating godets of a melt spinning machine in such a way that flexible and user-friendly handling is guaranteed for an operator, regardless of the process control.

Ein weiteres Ziel der Erfindung liegt darin, eine Vorrichtung zum Anlegen mehreren Fäden an rotierenden Galetten einer Schmelzspinnmaschine zur Verfügung zu stellen, bei welcher wahlweise die Fäden separat oder als Fadenschar führbar sind.Another object of the invention is to provide a device for applying a plurality of threads to rotating godets of a melt spinning machine, in which the threads can either be guided separately or as a thread sheet.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass dem Handinjektor eine Übergabeeinrichtung und ein zweiter Handinjektor zugeordnet sind.According to the invention, this object is achieved in that the hand injector is assigned a transfer device and a second hand injector.

Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale und Merkmalskombinationen der jeweiligen Unteransprüche definiert.Advantageous developments of the invention are defined by the features and combinations of features of the respective subclaims.

Die erfindungsgemäße Vorrichtung ist besonders vorteilhaft, um einen parallelen Abzug der Fäden durch eine erste Gruppe von rotierenden Galetten zu ermöglichen. So lassen sich die Fäden einzeln am Umfang der Galette durch einen der Handinjektoren anlegen. Der zum Anlegen aller Fäden üblicherweise in der Schmelzspinnmaschine vorhandene Handinjektor wird bei dieser Erfindung als Haupthandinjektor bezeichnet. Der zweite Handinjektor stellt somit einen Hilfshandinjektor dar, der hilfsweise zur Führung der Fäden einsetzbar ist. Insoweit bietet die erfindungsgemäße Vorrichtung dem Operator eine hohe Flexibilität beim Anlegen mehrerer Fäden an rotierenden Galetten.The device according to the invention is particularly advantageous in order to enable the threads to be drawn off in parallel by a first group of rotating godets. The threads can be individually applied to the circumference of the godet using one of the hand injectors. The one usually used to put on all threads Hand injector present in the melt spinning machine is referred to as the main hand injector in this invention. The second hand injector thus represents an auxiliary hand injector that can be used as an alternative for guiding the threads. In this respect, the device according to the invention offers the operator a high degree of flexibility when placing multiple threads on rotating godets.

Bevorzugt ist die Weiterbildung der erfindungsgemäßen Vorrichtung ausgeführt, bei welcher die Übergabeeinrichtung eine Einlegemulde zur Aufnahme eines Ansaugrohres des Haupthandinjektors und einen Einlauffadenführer aufweist, wobei der Einlauffadenführer an der Übergabeeinrichtung einem Saugende des in die Einlegemulde gelegten Ansaugrohres des Haupthandinjektors zugeordnet ist. Hierdurch kann der Haupthandinjektor in eine Parkposition versetzt werden, so dass der Operator zwischen dem Haupthandinjektor und dem Hilfshandinjektor wechseln kann. Die Führung des teilweise angelegten Fadens bleibt durch die Saugwirkung des Haupthandinjektors bestehen.The further development of the device according to the invention is preferably carried out, in which the transfer device has an insertion trough for receiving an intake pipe of the main handheld and an inlet thread guide, the intake thread guide on the transfer device being assigned to a suction end of the intake pipe of the main handler placed in the insertion trough. This allows the main hand injector to be placed in a parking position so that the operator can switch between the main hand injector and the auxiliary hand injector. The guidance of the partially applied thread remains due to the suction effect of the main handheld.

Um den nachfolgenden Anlegeprozess nur mit dem Haupthandinjektor fortsetzen zu können, ist eine Übergabe und Übernahme der nachfolgenden Fäden erforderlich. Zu diesem Zweck weist die Übergabeeinrichtung einen im Abstand zum Einlauffadenführer angeordneten Auslauffadenführer auf, wobei der Einlauffadenführer und der Auslauffadenführer mit der an der Übergabeeinrichtung angeordneten Schneideinrichtung eine Fadenlaufebene aufspannt. So können die mit dem Hilfshandinjektor geführten Fäden in einer definierten Position und Fadenstrecke geschnitten werden.In order to be able to continue the subsequent threading process only with the main hand injector, the subsequent threads must be handed over and taken over. For this purpose, the transfer device has an outlet thread guide arranged at a distance from the inlet thread guide, the inlet thread guide and the outlet thread guide spanning a thread running plane with the cutting device arranged on the transfer device. In this way, the threads guided with the auxiliary hand injector can be cut in a defined position and thread path.

Damit bei einem Durchtrennen eines im Hilfshandinjektor geführten Fadens dieser direkt aufgenommen werden kann, ist gemäß einer Weiterbildung der Erfindung das Saugende des Ansaugrohres am Haupthandinjektor nahe der Fadenlaufebene zwischen dem Einlauffadenführer und dem Auslauffadenführer positioniert. So lässt sich unmittelbar nach Durchtrennen des Fadens dieser von dem Saugende des Ansaugrohres am Hauptinjektor aufnehmen.So that when a thread guided in the auxiliary hand injector is severed, it can be picked up directly, according to a further development of the invention, the suction end of the suction pipe on the main hand injector is positioned near the thread running plane between the inlet thread guide and the outlet thread guide. Immediately after cutting the thread, it can be picked up from the suction end of the suction pipe on the main injector.

Die Schneideinrichtung ist hierzu bevorzugt an der Übergabeeinrichtung in einem Bereich zwischen dem Saugende des eingelegten Ansaugrohres am Haupthandinjektor und dem Auslauffadenführer angeordnet.For this purpose, the cutting device is preferably arranged on the transfer device in a region between the suction end of the inserted suction pipe on the main hand injector and the outlet thread guide.

Damit der Operator unmittelbar nach Einfädelung des mit dem Hilfshandinjektor geführten Fadens eine Fadentrennung bewirken kann, ist die Schneideinrichtung bevorzugt mit einem Aktor und einem mit dem Aktor gekoppelten Schneidmittel ausgestattet, wobei der Aktor elektrisch steuerbar ausgeführt ist.So that the operator can effect a thread separation immediately after threading the thread guided with the auxiliary hand injector, the cutting device is preferably equipped with an actuator and a cutting means coupled to the actuator, the actuator being designed to be electrically controllable.

Somit kann der Operator durch Betätigung einer Steuertaste eine Aktivierung und eine Durchtrennung des Fadens bewirken. Hierzu ist der Übergabeeinrichtung zumindest ein Bedienungsfeld mit einer Steuertaste zur Aktivierung der Schneideinrichtung zugeordnet, die in Bedienungsnähe angeordnet ist.The operator can thus activate and cut the thread by pressing a control button. For this purpose, the transfer device is assigned at least one control panel with a control button for activating the cutting device, which is arranged near the operator.

Um sowohl Fäden mit feinen Titern als auch Fäden mit groben Titern sicher durchtrennen zu können, ist das Schneidmittel aus zwei Scherenhälften gebildet. Diese lassen sich vorteilhaft durch einen Aktor betätigen.In order to be able to safely cut threads with fine titers as well as threads with coarse titers, the cutting means is formed from two scissor halves. These can advantageously be actuated by an actuator.

Damit möglichst wenig zusätzliche Fadenumschlingungen beim Anlegen der Fäden verursacht werden, ist die Weiterbildung der Erfindung besonders vorteilhaft, bei welcher die Übergabeeinrichtung an einer die Galetten tragenden Gestellwand zwischen einer Betriebsposition und einer Ruheposition beweglich gehalten ist. So kann die Übergabeeinrichtung in eine zur Bedienung und zur Fadenführung geeigneten Betriebsposition positioniert werden.In order that as little additional thread wrapping as possible is caused when the threads are put on, the development of the invention is particularly advantageous, in which the transfer device is held movably between an operating position and a rest position on a frame wall carrying the godets. The transfer device can thus be positioned in an operating position suitable for operation and thread guidance.

Die erfindungsgemäße Vorrichtung zum Anlegen mehrere Fäden an rotierenden Galetten ist besonders geeignet, um eine Fadenschar teilweise in Einzelführung der Fäden und teilweise in einer Scharenführung der Fäden anzulegen. Insoweit hat sich das erfindungsgemäße Verfahren bewährt, bei welchem alle Fäden am Ende gemeinsam durch den Haupthandinjektor geführt werden. Hierzu wird beim separaten Anlegen der Fäden zunächst ein erster gesponnener Faden mit dem Haupthandinjektor übernommen und um die rotierenden Galetten geführt. Anschließend wird der Faden in den Einlauffadenführer der Übergabeeinrichtung eingefädelt und der Haupthandinjektor mit seinem Saugrohr in der Übergabeeinrichtung geparkt. Nun wechselt der Operator zu dem Hilfshandinjektor, um einen nächsten benachbarten gesponnene Faden zu übernehmen und an den Galetten zu führen. Anschließend wird der Faden in den Einlauffadenführer und einem Auslauffadenführer an der Übergabeeinrichtung eingefädelt. Danach löst der Operator eine Aktivierung der Schneideinrichtung zum Durchtrennen des Fadens aus, wobei ein loses Ende des Fadens vom Haupthandinjektor aufgenommen wird. Dieser Vorgang lässt sich für jeden weiteren benachbarten Faden wiederholen, so dass am Ende des Anlegeprozesses an den Galetten alle Fäden gemeinsam durch den Haupthandinjektor führbar sind. Insoweit besteht die Möglichkeit, die Fadenschar in nachfolgende Behandlungsaggregate zu führen.The device according to the invention for applying a plurality of threads to rotating godets is particularly suitable for applying a family of threads partly in individual guidance of the threads and partly in a group of threads. In this respect, the method according to the invention has proven itself, in which all threads are ultimately passed through the main hand injector. For this purpose, when the threads are put on separately, a first spun thread with the main hand injector is first taken over and guided around the rotating godets. The thread is then threaded into the inlet thread guide of the transfer device and the main hand injector with its suction tube is parked in the transfer device. Now the operator changes to the auxiliary hand injector in order to take over a next neighboring spun thread and to guide it on the godets. The thread is then threaded into the inlet thread guide and an outlet thread guide at the transfer device. The operator then triggers an activation of the cutting device to cut the thread, with a loose end of the thread being picked up by the main hand injector. This process can be repeated for each additional neighboring thread, so that at the end of the application process on the godets, all threads can be passed through the main hand injector together. So far the possibility of guiding the coulter in subsequent treatment units.

Die erfindungsgemäße Vorrichtung zum Anlegen mehrerer Fäden wird nachfolgend anhand eines Ausführungsbeispiels näher beschrieben.The device according to the invention for applying a plurality of threads is described in more detail below using an exemplary embodiment.

In den Fig. 1 und 2 ist ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung zum Anlegen mehrerer Fäden gemeinsam mit einer Schmelzspinnmaschine in mehreren Ansichten dargestellt. Fig. 1 zeigt eine Vorderansicht der Schmelzspinnmaschine und Fig. 2 eine Seitenansicht. Insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für beide Figuren.In the Fig. 1 and 2nd An embodiment of the device according to the invention for applying several threads together with a melt spinning machine is shown in several views. Fig. 1 shows a front view of the melt spinning machine and Fig. 2 a side view. So far If no express reference is made to one of the figures, the following description applies to both figures.

Die Schmelzspinnmaschine ist hier nur teilweise mit einer Spinneinrichtung 1, einer Verstreckeinrichtung 8 und einer Kräuseleinrichtung 11 dargestellt, die zu einem Fadenlauf hintereinander angeordnet sind.The melt spinning machine is only partially shown here with a spinning device 1, a stretching device 8 and a crimping device 11, which are arranged one behind the other to form a thread run.

Üblicherweise erhalten die derart gekräuselten Fäden nach der Auflösung zu einem Faden eine Nachbehandlung durch eine Relaxtion und Verwirbelung. Am Ende weisen derartige Schmelzspinnmaschinen eine Aufwickeleinrichtung auf, um die Fäden einzeln zu Spulen zu wickeln. Auf die Darstellung der Nachbehandlungseinrichtung und der Aufwickeleinrichtung wurde an dieser Stelle verzichtet.Usually, the threads crimped in this way receive an aftertreatment by relaxation and intermingling after dissolving into a thread. At the end, such melt spinning machines have a winding device in order to wind the threads individually into bobbins. The post-treatment device and the rewinder are not shown at this point.

Die Spinneinrichtung 1 weist einen Spinnbalken 2 und drei an der Unterseite des Spinnbalkens 2 nebeneinander angeordnete Spinndüsen 3.1, 3.2 und 3.3 auf. Der Spinnbalken 2 ist üblicherweise beheizt ausgeführt und enthält ein Schmelzeverteilersystem sowie eine oder mehrere Spinnpumpen. Eine von einer Schmelzequelle zugeführte Polymerschmelze wird über einen Zulauf 4 den Spinndüsen 3.1 bis 3.3 zugeführt.The spinning device 1 has a spinning beam 2 and three spinnerets 3.1, 3.2 and 3.3 arranged next to one another on the underside of the spinning beam 2. The spinning beam 2 is usually heated and contains a melt distribution system and one or more spinning pumps. A polymer melt supplied from a melt source is fed to the spinnerets 3.1 to 3.3 via an inlet 4.

Unterhalb des Spinnbalkens 2 ist eine Kühleinrichtung 5 vorgesehen, um die durch die Spinndüsen 3.1 bis 3.3 extrudierten Filamentstränge abzukühlen. Die Kühleinrichtung 5 weist in diesem Ausführungsbeispiel eine Blaskammer 5.1 und eine Blaswand 5.2 auf, die den Filamentsträngen zugewandt ist.A cooling device 5 is provided below the spinning beam 2 in order to cool the filament strands extruded through the spinnerets 3.1 to 3.3. In this exemplary embodiment, the cooling device 5 has a blowing chamber 5.1 and a blowing wall 5.2, which faces the filament strands.

Unterhalb der Kühleinrichtung 5 ist jeder Spinndüse 3.1 bis 3.3 jeweils ein Sammelfadenführer 6 zum Bündeln der Filamente zu jeweils einem Faden 7.1, 7.2 und 7.3 zugeordnet.Below the cooling device 5, each spinneret 3.1 to 3.3 is assigned a collecting thread guide 6 for bundling the filaments into a thread 7.1, 7.2 and 7.3, respectively.

Unterhalb der Sammelfadenführer 6 ist eine Saug-Schneideinrichtung 38 vorgesehen, um bei einem Fadenbruch oder einem Anspinnen die Fäden kontinuierlich aufzunehmen und zu einem Abfallbehälter zu fördern.A suction cutting device 38 is provided beneath the collecting thread guides 6 in order to continuously pick up the threads in the event of a thread breakage or spinning and to convey them to a waste container.

Die Fäden 7.1, 7.2 und 7.3 werden einzeln über mehrere Abzugsgaletten 9.1 bis 9.3 abgezogen. Den Abzugsgaletteneinheiten 9.1 bis 9.3 ist die Verstreckeinrichtung 8 nachgeordnet. Die Verstreckeinrichtung 8 weist in diesem Ausführungsbeispiel mehrere Galetten 10.1 bis 10.4 auf, die jeweils zwei Galettenduo bilden, um die Fäden 7.1, 7.2 und 7.3 zu verstrecken. Die Galetten 10.1 bis 10.4 weisen hierzu üblicherweise beheizte Galettenmäntel auf. Die Galetten 10.1 bis 10.2 sind mit Antrieben gekoppelt, um insbesondere zwischen den Galettenduo eine Differenzgeschwindigkeit einstellen zu können.The threads 7.1, 7.2 and 7.3 are drawn off individually via a plurality of take-off godets 9.1 to 9.3. The stretching device 8 is arranged downstream of the take-off godet units 9.1 to 9.3. In this exemplary embodiment, the stretching device 8 has a plurality of godets 10.1 to 10.4, which each form two pairs of godets, in order to stretch the threads 7.1, 7.2 and 7.3. For this purpose, the godets 10.1 to 10.4 usually have heated godet shells. The godets 10.1 to 10.2 are coupled to drives in order to be able to set a differential speed in particular between the godet duo.

Der Verstreckeinrichtung 8 folgt im Fadenlauf die Kräuseleinrichtung 11, die in diesem Ausführungsbeispiel der Schmelzspinnmaschine durch ein Texturieraggregate 12 und eine Kühltrommel 14 gebildet sind. Das Texturieraggregat 12 weist vorzugsweise mehrere Förderdüsen auf, um die Fäden 7.1 bis 7.3 separat in jeweils eine angeschlossene Stauchkammer zu fördern. Auf der Auslassseite des Texturieraggregates 12 werden die Fäden als Fadenstopfen abgeführt und am Umfang der Kühltrommel 14 abgelegt. Nach Abkühlung der Fadenstopfen am Umfang der Kühltrommel werden diese jeweils zu einem gekräuselten Faden abgezogen.The stretching device 8 is followed in the thread run by the crimping device 11, which in this exemplary embodiment of the melt spinning machine is formed by a texturing unit 12 and a cooling drum 14. The texturing unit 12 preferably has a plurality of conveying nozzles in order to convey the threads 7.1 to 7.3 separately into a respective stuffer box. On the outlet side of the texturing unit 12, the threads are removed as thread plugs and placed on the circumference of the cooling drum 14. After the thread plugs on the circumference of the cooling drum have cooled, they are pulled off to form a crimped thread.

Wie insbesondere aus der Darstellung in Fig. 2 hervorgeht, sind die Verstreckeinrichtung 8 und die Kräuseleinrichtung 11 an einer Gestellwand 13 auskragend angeordnet. Der Gestellwand 13 ist in Front ein Bedienungsgang 32 zugeordnet, der sich an einer Maschinenlängsseite erstreckt. Insoweit wird die Verstreckeinrichtung 8 und die Kräuseleinrichtung 11 von dem Bedienungsgang 32 aus bedient.As shown in particular in Fig. 2 shows, the stretching device 8 and the crimping device 11 are arranged cantilevered on a frame wall 13. The frame wall 13 is assigned an operating aisle 32 in the front, which extends on a machine longitudinal side. In this respect, the stretching device 8 and the crimping device 11 are operated from the operating aisle 32.

In den Fig. 1 und 2 ist die Schmelzspinnmaschine in einer Betriebssituation dargestellt, bei welcher die Fäden kontinuierlich verstreckt, gekräuselt und nachbehandelt sowie aufgewickelt werden. Um im Prozess zur Herstellung der gekräuselten Fäden starten zu können, ist es erforderlich, dass ein Operator die Fäden 7.1 bis 7.3 nach dem Anspinnen in der Spinneinrichtung 1 an die Abzugsgaletteneinheiten 9.1 bis 9.3 und in die Verstreckeinrichtung 8 anlegt. Hierzu bedient sich der Operator der erfindungsgemäßen Vorrichtung, die in den Fig. 1 und 2 schematisch dargestellt ist.In the Fig. 1 and 2nd the melt spinning machine is shown in an operating situation in which the threads are continuously drawn, crimped and aftertreated and wound up. In order to be able to start in the process for producing the crimped threads, it is necessary for an operator to apply the threads 7.1 to 7.3 after spinning in the spinning device 1 to the take-off godet units 9.1 to 9.3 and in the drawing device 8. For this purpose, the operator uses the device according to the invention, which in the Fig. 1 and 2nd is shown schematically.

Das Ausführungsbeispiel der erfindungsgemäßen Vorrichtung weist einen Haupthandinjektor 16 auf, der manuell geführt wird und mit einem hier nicht dargestellten Abfallbehälter verbunden ist. Dem Haupthandinjektor 16 ist eine Übergabeeinrichtung 17 sowie ein Hilfshandinjektor 18 zugeordnet. Der Hilfshandinjektor 18 ist ebenfalls manuell frei führbar und mit einem hier nicht dargestellten Abfallbehälter verbunden. Die Übergabeeinrichtung 17 ist an der Gestellwand 13 beweglich angeordnet. Hierzu weist die Übergabeeinrichtung 17 einen Schubträger 30 auf, der an der Gestellwand 13 verschiebbar geführt ist.The exemplary embodiment of the device according to the invention has a main hand injector 16 which is guided manually and is connected to a waste container (not shown here). A transfer device 17 and an auxiliary hand injector 18 are assigned to the main hand injector 16. The auxiliary hand injector 18 is also manually freely guided and connected to a waste container, not shown here. The transfer device 17 is movably arranged on the frame wall 13. For this purpose, the transfer device 17 has a thrust carrier 30 which is guided on the frame wall 13 so as to be displaceable.

Zur weiteren Erläuterung der Übergabeeinrichtung 17 wird zusätzlich zu der Fig. 3 Bezug genommen, die mehrere Ansichten der Übergabeeinrichtung 17 zeigt. In Fig. 3.1 ist eine Vorderansicht und in Fig. 3.2 eine Draufsicht dargestellt. Am freien Ende des Schubträgers 30 ist eine Trägerplatte 29 angeordnet. An der Trägerplatte 29 ist auf einer Einlaufseite ein Einlauffadenführer 22 und auf einer Auslaufseite ein Auslauffadenführer 23 angeordnet. Zwischen dem Einlauffadenführer 22 und dem Auslauffadenführer 23 ist an der Trägerplatte 29 eine Einlegmulde 19 seitlich auskragend angeordnet. Im Bereich zwischen der Einlegmulde 19 und dem Auslauffadenführer 23 ist eine Schneideinrichtung 24 an der Trägerplatte 29 gehalten. Die Schneideinrichtung 24 weist ein Schneidmittel 25 und einen Aktor 26 auf. Der Aktor 26 ist über eine Steuertaste 28 an einem Bedienungsfeld 27 steuerbar. Das Bedienungsfeld 27 ist an der Gestellwand 13 gehalten.To further explain the transfer device 17, in addition to the Fig. 3 Reference, which shows several views of the transfer device 17. In Fig. 3.1 is a front view and in Fig. 3.2 shown a top view. A carrier plate 29 is arranged at the free end of the thrust carrier 30. An inlet thread guide 22 is arranged on the carrier plate 29 on an inlet side and an outlet thread guide 23 is arranged on an outlet side. Between the inlet thread guide 22 and the outlet thread guide 23, an insertion trough 19 is laterally cantilevered on the carrier plate 29. A cutting device 24 is held on the carrier plate 29 in the region between the insertion trough 19 and the outlet thread guide 23. The cutting device 24 has a cutting means 25 and an actuator 26. The actuator 26 can be controlled via a control button 28 on a control panel 27. The control panel 27 is held on the frame wall 13.

Zur Erläuterung der erfindungsgemäßen Vorrichtung zum Anlegen der Fäden wird nachfolgend auf die Figuren 4 und 5 sowie 6 und 7 Bezug genommen.To explain the device for applying the threads according to the invention, reference is made to the Figures 4 and 5 as well as 6 and 7 referenced.

In der Fig. 4 ist die Vorderansicht der Schmelzspinnmaschine gezeigt, wobei ein erster Faden an die Abzugsgaletteneinheit 9 und die Verstreckeinrichtung 8 angelegt ist. Die Fig. 5 zeigt schematisch eine Draufsicht der erfindungsgemäßen Vorrichtung in der Situation gemäß Fig. 4.In the Fig. 4 the front view of the melt spinning machine is shown, with a first thread being applied to the take-off godet unit 9 and the stretching device 8. The Fig. 5 schematically shows a top view of the device according to the invention in the situation according to Fig. 4 .

Um einen Prozess starten zu können, wird der Operator den Haupthandinjektor 16 führen, um den Faden 7.1 aus der Spinneinrichtung 1 zu übernehmen und zunächst an die Abzugsgaletteneinheit 9 sowie die nachfolgenden Galetten 10.1 bis 10.4 der Verstreckeinrichtung anzulegen. Danach wird der Faden 7.1 in den Einlauffadenführer 22 der Übergabeeinrichtung 17 eingefädelt und der Haupthandinjektor 16 wird zum Parken in die Einlegemulde 19 der Übergabeeinrichtung 17 eingelegt. Diese Situation ist in Fig. 5 dargestellt.In order to be able to start a process, the operator will guide the main hand injector 16 in order to take the thread 7.1 from the spinning device 1 and to first lay it on the take-off godet unit 9 and the subsequent godets 10.1 to 10.4 of the stretching device. After that the thread 7.1 is threaded into the inlet thread guide 22 of the transfer device 17 and the main hand injector 16 is inserted into the insertion recess 19 of the transfer device 17 for parking. This situation is in Fig. 5 shown.

In Fig. 5 ist die Übergabeeinrichtung 17 in der Draufsicht gezeigt, wobei der Schubträger 30 mit der Trägerplatte 29 in einer ausgezogenen Stellung an der Gestellwand 13 gehalten ist. Der Einlauffadenführer 22 und der Auslauffadenführer 23 bilden gemeinsam mit der dazwischenliegenden Schneideinrichtung 24 eine Fadenlaufebene 31. Die Fadenlaufebene 31 ist in der Fig. 5 gestrichelt dargestellt.In Fig. 5 the transfer device 17 is shown in plan view, the thrust carrier 30 with the carrier plate 29 being held in an extended position on the frame wall 13. The inlet thread guide 22 and the outlet thread guide 23 together with the intermediate cutting device 24 form a thread running plane 31. The thread running plane 31 is in the Fig. 5 shown in dashed lines.

In der Parksituation des Haupthandinjektors 16 ragt ein Ansaugrohr 20 des Haupthandinjektors 16 mit einem Saugende 21 bis zur Fadenlaufebene 31. Die Einlegmulde 19 weist hierzu hier nicht näher dargestellte Anschläge auf, um das Ansaugrohr 20 positionieren zu können.In the parking situation of the main hand injector 16, an intake pipe 20 of the main hand injector 16 projects with a suction end 21 up to the thread running plane 31.

In der dargestellten Anlegesituation wird der Faden 7.1 kontinuierlich über den Haupthandinjektor 16 aufgenommen und abgeführt.In the illustrated situation, the thread 7.1 is continuously picked up and removed via the main hand injector 16.

Nun nimmt der Operator den Hilfshandinjektor 18, um einen benachbarten Faden in der Spinneinrichtung 1 zu übernehmen. Die Fig. 6 zeigt die Schmelzspinnmaschine mit der erfindungsgemäßen Vorrichtung in einer Vorderansicht und Fig. 7 stellt die erfindungsgemäße Vorrichtung in einer Draufsicht dar.Now the operator takes the auxiliary hand injector 18 to take over an adjacent thread in the spinning device 1. The Fig. 6 shows the melt spinning machine with the device according to the invention in a front view and Fig. 7 represents the device according to the invention in a plan view.

Insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für beide Figuren.Insofar as no express reference is made to one of the figures, the following description applies to both figures.

Wie aus der Darstellung in Fig. 6 hervorgeht, lässt sich der Faden 7.2 mit Hilfe des Hilfshandinjektors 18 an die Abzugsgaletteneinheit 9.2 und an die Galetten 10.1 bis 10.4 anlegen. Anschließend wird der Faden 7.2 in den Einlauffadenführer 22 und dem Auslauffadenführer 23 der Übergabeeinrichtung 17 eingefädelt. Der Faden 7.2 wird in dieser Situation in der Fadenlaufebene 31 geführt und kontinuierlich von dem Hilfshandinjektor 18 aufgenommen und zu einem Abfallbehälter gefördert.As shown in Fig. 6 emerges, the thread 7.2 can be applied to the take-off godet unit 9.2 and to the godets 10.1 to 10.4 using the auxiliary hand injector 18. The thread 7.2 is then threaded into the inlet thread guide 22 and the outlet thread guide 23 of the transfer device 17. In this situation, the thread 7.2 is guided in the thread running plane 31 and continuously picked up by the auxiliary hand injector 18 and conveyed to a waste container.

Nun betätigt der Operator die Steuertaste 28, um die Schneideinrichtung 24 zu aktivieren. Der Faden 7.2 wird innerhalb der Übergabeeinrichtung 17 durch das Schneidmittel 25 durchtrennt. Das Schneidmittel 25 ist hierbei bevorzugt durch zwei Scherenhälften gebildet, die sich gegensinnig zueinander bewegen, um den Faden 7.2 zu durchtrennen.The operator now actuates the control button 28 in order to activate the cutting device 24. The thread 7.2 is severed within the transfer device 17 by the cutting means 25. The cutting means 25 is preferably formed by two scissor halves which move in opposite directions to one another in order to cut the thread 7.2.

Nachdem der Faden 7.2 durchtrennt ist, wird über die Saugkraft des Ansaugrohres 20 am Haupthandinjektor 16 das lose Fadenende des Fadens 7.2 eingesogen und somit von dem Haupthandinjektor 16 übernommen.After the thread 7.2 has been severed, the loose thread end of the thread 7.2 is drawn in via the suction force of the suction pipe 20 on the main hand injector 16 and is thus taken over by the main hand injector 16.

Nun ist der Hilfshandinjektor 18 frei, um einen nächsten Faden aus der Spinneinrichtung 1 anlegen zu können. Der zuvor beschriebene Vorgang wiederholt sich, so dass nach Durchtrennung des Fadens 7.3 in der Übergabeeinrichtung 17 alle Fäden gemeinsam von dem Haupthandinjektor 16 geführt sind. Der weitere Anlegeprozess erfolgt durch den Haupthandinjektor 16, wobei die Fäden 7.1, 7.2 und 7.3 als eine Fadenschar gemeinsam geführt werden.The auxiliary hand injector 18 is now free to be able to put on a next thread from the spinning device 1. The process described above is repeated, so that after the thread 7.3 has been severed in the transfer device 17, all threads are guided together by the main hand injector 16. The further application process is carried out by the main hand injector 16, the threads 7.1, 7.2 and 7.3 being guided together as a family of threads.

Die erfindungsgemäße Vorrichtung ist somit besonders geeignet, um die Fäden separat und einzeln mit mehreren Umschlingungen an lang auskragenden Galetten anzulegen. Nachdem der Anlegevorgang beendet ist, wird die Übergabeeinrichtung 17 wieder zurückgesetzt, um in einer eingeschobenen Position zu verharren.The device according to the invention is therefore particularly suitable for applying the threads separately and individually with a plurality of loops on long cantilevered godets. After the application process has ended, the transfer device 17 is reset in order to remain in an inserted position.

Die in den Fig. 1 und Fig. 2 dargestellte Schmelzspinnmaschine sowie die Anzahl der Spinndüsen ist nur beispielhaft. Grundsätzlich lassen sich auch mehr als drei Fäden nach dem erfindungsgemäßen Verfahren separat oder gemeinsam zum Anlegen führen.The in the Fig. 1 and Fig. 2 Melt spinning machine shown and the number of spinnerets is only exemplary. In principle, more than three threads can also be guided separately or together by the method according to the invention.
