Description

Die Erfindung betrifft eine Vorrichtung zum Aufwickeln eines Fadens auf eine Spulenhülse mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for winding a thread on a bobbin tube with the features from the preamble of claim 1.

Vorrichtungen mit diesen Merkmalen sind an sich bekannt und beispielsweise in DE-OS 39 39 595 und US-PS 3 347 490 beschrieben.Devices with these features are known per se and are described, for example, in DE-OS 39 39 595 and US Pat. No. 3,347,490.

Derartige Vorrichtungen werden an Textilmaschinen, beispielsweise Doppeldraht-Zwirnmaschinen, eingesetzt, um die von der Textilmaschine gelieferten Fäden beispielsweise auf Kreuzspulen aufzuwickeln.Devices of this type are used on textile machines, for example double-wire twisting machines, in order to wind up the threads supplied by the textile machine, for example on cross-wound bobbins.

Die dabei verwendete Doppelchangierung dient dazu, einen Längen- und damit auch Spannungsausgleich des Fadens im sogenannten Changierdreieck vor dem Fadeneinlauf in die Spulenperipherie zu erreichen.The double traversing used serves to equalize the length and thus tension of the thread in the so-called traversing triangle before the thread entry into the bobbin periphery.

Da bei einer Doppelchangierung der Faden über mindestes drei Fadenumlenkvorrichtungen geführt wird, ist beim Bedienen der Vorrichtung die Einfädelung erschwert.Since the thread is guided over at least three thread deflecting devices in the case of double traversing, the threading is difficult when the device is operated.

Bei Vorrichtungen zum Aufwickeln eines Fadens mit Einfachchangierung ist es bekannt, zum Einfädeln das von der Fadenzuführungsvorrichtung kommende Fadenende mittels einer Vorrichtung zum Festklemmen des Fadenendes an einem Ende der Spulenhülse festzulegen. Der Changierfadenführer ist so gestaltet, daß der Faden beim Hin- und Hergang des Changierfadenführers selbständig in diesen eingefädelt wird. Dieses Verfahren stößt bei der Doppelchangierung mit mehreren Fadenumlenkvorrichtungen auf erhebliche Schwierigkeiten.In devices for winding up a thread with a single threading, it is known for threading to fix the thread end coming from the thread supply device by means of a device for clamping the thread end at one end of the bobbin tube. The traversing thread guide is designed so that the thread is automatically threaded into the traversing thread guide as it goes back and forth. This method encounters considerable difficulties in double traversing with several thread deflecting devices.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Aufwickeln eines Fadens auf eine Spulenhülse mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1 so auszugestalten, daß nach dem Festklemmen des Fadenendes an einem Ende der Spulenhülse beim Anlaufen des Aufwickelvorgangs durch das Antreiben der Spulenhülse sowie des Hauptchangierfadenführers und des Ausgleichschangierfadenführers ein automatischer Einfädelvorgang einsetzt, an dessen Ende der Faden von der Fadenzuführungsvorrichtung über die erste Fadenumlenkvorrichtung, die dritte Fadenumlenkvorrichtung und die zweite Fadenumlenkvorrichtung und den Hauptchangierfadenführer zur Spulenhülse läuft.The invention has for its object to provide a device for winding a thread on a bobbin with the features from the preamble of claim 1 so that after clamping the thread end at one end of the bobbin tube when starting the winding process by driving the bobbin tube and Main thread guide and the compensating thread guide uses an automatic threading process, at the end of which the thread from the thread feed device via the first thread deflection device, the third thread deflection device and the second thread deflection device and runs the main traverse to the bobbin tube.

Die Lösung dieser Aufgabe erfolgt bei einer gattungsgemäßen Vorrichtung mittels einer Fadeneinfädeleinrichtung die die Merkmale aus dem kennzeichnenden Teil des Patentanspruchs 1 aufweist.This object is achieved in a generic device by means of a threading device which has the features from the characterizing part of patent claim 1.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous developments of the invention are described in the subclaims.

Der Grundgedanke der Erfindung besteht darin, den an einem Ende der Spulenhülse festgeklemmten Faden an einer Stelle zwischen der Fadenzuführungsvorrichtung und der ersten Fadenumlenkvorrichtung zunächst soweit in einer Richtung parallel zu den Bewegungsbahnen der beiden Changierfadenführer zu bewegen, bis er die erste fest angeordnete Fadenumlenkvorrichtung überlaufen hat. Diese Bewegung wird mindestens in ihrem zweiten Teil von einem ersten, an der mit dem Hauptchangierfadenführer verbundenen zweiten Fadenumlenkvorrichtung angeordneten, Mitnehmer bewirkt, wobei der Faden in die zweite Fadenumlenkvorrichtung eingefädelt wird. Der Faden wird sodann von einem mit dem Hauptchangierfadenführer verbundenen zweiten Mitnehmer ergriffen und wieder zurückbewegt. Bei dieser Bewegung wird er zunächst in die erste Fadenumlenkvorrichtung eingefädelt, und die zwischen der ersten und der zweiten Fadenumlenkvorrichtung entstehende Fadenschlaufe wird über die am Ausgleichschangierfadenführer angeordnete dritte Fadenumlenkvorrichtung hinweggeführt. Nach der erneuten Umkehr der Bewegungsrichtung wird diese Fadenschlaufe vom zweiten Mitnehmer freigegeben und von einem an der dritten Fadenumlenkvorrichtung angeordneten dritten Mitnehmer ergriffen und in die dritte Fadenumlenkvorrichtung am Ausgleichschangierfadenführers eingefädelt. Damit ist der Faden über alle drei Fadenumlenkvorrichtungen geführt und der Einfädelvorgang ist beendet. Einzelheiten der Vorrichtungsteile welche die oben beschriebenen Vorgänge bewirken werden weiter unten anhand eines Ausführungsbeispiels erläutert.The basic idea of the invention is to first move the thread clamped at one end of the bobbin tube at a point between the thread feed device and the first thread deflection device in a direction parallel to the movement paths of the two traversing thread guides until it has overflowed the first fixed thread deflection device. This movement is effected at least in its second part by a first driver arranged on the second thread deflecting device connected to the main traversing thread guide, the thread being threaded into the second thread deflecting device. The thread is then gripped by a second driver connected to the main traversing thread guide and moved back again. During this movement, it is first threaded into the first thread deflecting device, and the thread loop created between the first and the second thread deflecting device is guided over the third thread deflecting device arranged on the compensating traversing thread guide. After the direction of movement is reversed again, this thread loop becomes the second driver released and gripped by a third driver arranged on the third thread deflecting device and threaded into the third thread deflecting device on the compensating traversing thread guide. The thread is then guided over all three thread deflecting devices and the threading process is ended. Details of the device parts which bring about the processes described above are explained below using an exemplary embodiment.

Das Festklemmen des Fadenendes an einem Ende der Spulenhülse zur Einleitung des Einfädelvorgangs kann von Hand vorzugsweise mit einer Vorrichtung durchgeführt werden, wie sie beispielsweise in DE-OS 23 12 609 beschrieben ist oder automatisch gemäß einem Verfahren und einer Vorrichtung die in der nicht vorveröffentlichten DE-OS 40 34 482 beschrieben sind.Clamping the thread end at one end of the bobbin tube to initiate the threading process can preferably be carried out manually using a device such as that described in DE-OS 23 12 609 or automatically according to a method and a device described in the unpublished DE- OS 40 34 482 are described.

Die Fadenumlenkvorrichtungen können als Fadenumlenkrollen ausgebildet sein. Weiterhin hat es sich wegen der geringen Abstände der gegeneinander changierenden Teile aus Sicherheitsgründen als zweckmäßig erwiesen, wenn in Bereich zwischen der Fadenzuführungsvorrichtung und dem Hauptchangierfadenführer oberhalb der Fadenumlenkvorrichtungen ein Abdeckblech angeordnet ist, das beispielsweise aus durchsichtigem Material bestehen kann, um eine optische Kontrolle der Vorgänge zu ermöglichen.The thread deflection devices can be designed as thread deflection rollers. Furthermore, because of the small distances between the mutually changing parts, it has proven to be expedient for safety reasons if, in the area between the thread feeding device and the main traversing thread guide, a cover plate is arranged above the thread deflecting devices, which can consist, for example, of transparent material in order to visually control the processes enable.

Es soll zunächst anhand der Fig. 1 und 2 der Aufbau und Bewegungsablauf bei einer üblichen Vorrichtung zum Aufwickeln eines Fadens auf eine Spulenhülse mit Doppelchangierung näher erläutert werden. Die in Fig. 1 dargestellte Vorrichtung ist einer Doppeldraht-Zwirnspindel zugeordnet, von der schematisch das Fadeneinlaufrohr 1, der Spulentopf 2 mit darin eingesetzter Ablaufspule 3 sowie der Ballonbegrenzer 4 dargestellt sind. Der von der Ablaufspule 3 abgezogene Faden wird nach Durchlaufen des Fadeneinlaufrohres 1 und der nicht dargestellten angetriebenen Fadenspeicherscheibe unter Bildung eines Fadenballons 5 aus der Doppeldraht-Zwirnspindel herausgeführt. Der Fadenballon 5 findet seine obere Begrenzung im Ballonfadenführer 6 von dem der Faden F über Umlenkrollen 7 zur Voreilrolle 8 läuft, die auf einer von außen angetriebenen Welle befestigt ist. Die Umlenkrollen 7 sowie der Ballonfadenführer 6 sind an Träger 9 des Maschinengestells gelagert. Die Voreilrolle 8 stellt die Fadenzuführungsvorrichtung für die eigentliche Aufwickelvorrichtung dar.It should first of all with reference to FIGS. 1 and 2 Structure and sequence of movements in a conventional device for winding a thread on a bobbin tube with double traverse are explained in more detail. The device shown in FIG. 1 is assigned to a double-wire twisting spindle, of which the thread inlet tube 1, the bobbin pot 2 with the bobbin 3 inserted therein and the balloon limiter 4 are shown schematically. The thread drawn off from the take-off spool 3 is passed out of the double-wire twisting spindle after passing through the thread inlet tube 1 and the driven thread storage disk, not shown, to form a thread balloon 5. The thread balloon 5 finds its upper limit in the balloon thread guide 6 from which the thread F runs over deflection rollers 7 to the lead roller 8, which is attached to an externally driven shaft. The deflection rollers 7 and the balloon thread guide 6 are mounted on the carrier 9 of the machine frame. The lead roller 8 represents the thread feeding device for the actual winding device.

Im Anschluß an die Voreilrolle 8 ist der Faden über eine erste Fadenumlenkrolle 12 geführt die fest am Maschinengestell angeordnet ist. Von dort läuft der Faden zu einer zweiten Fadenumlenkrolle 14 die mit dem Hauptchangierfadenführer 14.2 verbunden ist. Zwischen der ersten Fadenumlenkrolle 12 und der zweiten Fadenumlenkrolle 14 läuft der Faden noch über die den Ausgleichschangierfadenführer darstellende dritte Fadenumlenkrolle 13. Vom Hauptchangierfadenführer 14.2 aus läuft der Faden auf eine Spule SP, die auf einer in Fig. 1 nicht sichtbaren Spulenhülse 15 aufgewickelt wird. Die Spulenhülse 15 ist in einem Spulenrahmen zwischen Spulenrahmenarmen 16.1 und 16.2 gehaltert und zwar über Zentrierteller 18.1 bzw. 18.2. Der Antrieb der Spulenhülse 15 bzw. der Spule SP erfolgt mittels einer von außen angetriebenen Friktionsantriebswalze 17.Following the lead roller 8, the thread is guided over a first thread guide roller 12 which is fixedly arranged on the machine frame. From there the thread runs to a second thread deflection roller 14 which is connected to the main traversing thread guide 14.2. Between the first thread deflecting roller 12 and the second thread deflecting roller 14, the thread still runs over the third thread deflecting roller 13 representing the compensating traversing thread guide 15 is wound up. The coil sleeve 15 is held in a coil frame between the coil frame arms 16.1 and 16.2, specifically via centering plates 18.1 and 18.2. The coil sleeve 15 or the coil SP is driven by means of an externally driven friction drive roller 17.

Der Hauptchangierfadenführer 14.2 ist an einer hin- und herbewegbaren Fadenführerstange 14.1 befestigt, während die den Ausgleichschangierfadenführer darstellende dritte Fadenumlenkrolle 13 an einer ebenfalls hin- und herbewegbaren Fadenführerstange 13.1 angeordnet ist.The main traversing thread guide 14.2 is fastened to a back and forth movable thread guide rod 14.1, while the third thread guide roller 13, which represents the compensating traversing thread guide, is arranged on a thread guide rod 13.1 which can also be moved back and forth.

Die Bewegungsbahn des Hauptchangierfadenführers ist in Fig. 1 mit B1, die des Ausgleichschangierfadenführers mit B2 bezeichnet.The path of movement of the main tracer guide is designated B1 in Fig. 1, that of the compensating tracer guide with B2.

Der bei einer derartigen Vorrichtung mit Doppelchangierung auftretende Bewegungsablauf ist aus Fig. 2 abzulesen.The sequence of movements occurring in such a device with double traversing can be read from FIG. 2.

In Fig. 2 sind die Positionen der drei Fadenumlenkrollen in drei unterschiedlichen Stellungen des Hauptchangierfadenführers und des Ausgleichschangierfadenführers dargestellt. Dabei ist mit ausgezogenen Linien die in Fig. 2 linke Endposition der zweiten Fadenumlenkrolle 14 und der dritten Fadenumlenkrolle 13 zusammen mit der festen Position der Fadenumlenkrolle 12 dargestellt. Gestrichelt sind jeweils eine mittlere Position und die in Fig. 2 rechte Endposition der Fadenumlenkrollen 14 und 13 dargestellt. Bekanntlich gilt bei der Doppelchangierung die Gesetzmäßigkeit, daß der Hauptchangierfadenführer den vollen Hub a ausführt, während in der zeitgleichen Phase der Ausgleichschangierfadenführer den halben Hub a/2 durchführt. Der Vollhub a entspricht im wesentlichen der Länge der Spule SP, und die Bewegungsbahn des Ausgleichschangierfadenführers mit dem Hub a/2 erfolgt parallel zur Bewegungsbahn des Hauptchangierfadenführers in einem Bereich der im wesentlichen zwischen der Mitte und einem Ende der Spulenhülse liegt, wobei die in Fig. 2 rechte Position der dritten Fadenumlenkrolle 13 bereits außerhalb des Endes der Spulenhülse liegen kann. Der Faden läuft in Pfeilrichtung P1 zur ersten Fadenumlenkrolle 12 und wird in Pfeilrichtung P2 von der zweiten Fadenumlenkrolle 14 über den nicht dargestellten Hauptchangierfadenführer der Spule SP zugeführt. Wie aus Fig. 2 unmittelbar abzulesen, ist die Länge des Fadenstücks zwischen der ersten Fadenumlenkrolle 12 und der zweiten Fadenumlenkrolle 14 in allen Stellungen des Hauptchangierfadenführers und des Ausgleichschangierfadenführers gleich.2 shows the positions of the three thread deflecting rollers in three different positions of the main guiding thread guide and the compensating traversing thread guide. The left end position in FIG. 2 of the second thread deflection roller 14 and the third thread deflection roller 13 is shown with solid lines together with the fixed position of the thread deflection roller 12. A middle position and the right end position of the thread deflection rollers 14 and 13 in FIG. 2 are shown in broken lines. As is known, the principle of double traversing is that the main traversing thread guide has the full stroke a executes, while in the simultaneous phase the compensating baling thread guide performs half the stroke a / 2. The full stroke a corresponds essentially to the length of the spool SP, and the path of movement of the compensating trailing thread guide with the stroke a / 2 takes place parallel to the trajectory of the main trailing thread guide in a region which lies essentially between the center and one end of the bobbin tube, the position shown in Fig. 2 right position of the third thread deflection roller 13 may already lie outside the end of the bobbin tube. The thread runs in the arrow direction P1 to the first thread deflection roller 12 and is fed in the arrow direction P2 from the second thread deflection roller 14 via the main traversing thread guide (not shown) to the spool SP. As can be seen directly from FIG. 2, the length of the thread piece between the first thread deflection roller 12 and the second thread deflection roller 14 is the same in all positions of the main trailing thread guide and the compensating traversing thread guide.

Es wird nun im folgenden zunächst anhand von Fig. 3 der grundsätzliche Aufbau einer Aufwickelvorrichtung gemäß Fig. 1 mit einer Fadeneinfädeleinrichtung erläutert. In Fig. 3 ist die Vorrichtung im eingefädelten Zustand dargestellt, in dem der Faden F von der Voreilrolle 8 kommend um die erste Fadenumlenkrolle 12, sodann um die dritte Fadenumlenkrolle 13 und schließlich um die zweite Fadenumlenkrolle 14 läuft, um dann über den Hauptchangierführer 14.2 der Spulenhülse 15 zugeführt zu werden. Strichpunktiert ist der Fadenverlauf F' vor Beginn des Einfädelvorgangs angedeutet.The basic structure of a winding device according to FIG. 1 with a thread threading device will now be explained below with reference to FIG. 3. In Fig. 3 the device is shown in the threaded state, in which the thread F coming from the leading roller 8 around the first thread deflection roller 12, then around the third thread deflection roller 13 and finally around the second thread deflection roller 14, and then via the main traverse guide 14.2 Coil tube 15 to be fed. The course of the thread F 'is indicated by dash-dotted lines before the beginning of the threading process.

Es werden nunmehr die einzelnen Einrichtungsteile der Fadeneinfädeleinrichtung erläutert.The individual parts of the threading device are now explained.

Die Vorrichtung zum Festklemmen des Fadens befindet sich an dem in Fig. 3 rechten Ende der Spulenhülse 15 und liegt somit der Bewegungsbahn des Ausgleichschangierfadenführers, also der dritten Fadenumlenkrolle 13 gegenüber. Das in Fig. 3 rechte Ende 15.1 der Spulenhülse 15 wird im folgenden als "erstes Ende" bezeichnet. Die an sich bekannte Vorrichtung zum Festklemmen des Fadens wird nicht näher erläutert. Es genügt festzuhalten, daß das Fadenende wie beispielsweise aus Fig. 4 ersichtlich zwischen den Zentrierteller 18.1 und das erste Ende 15.1 der Spulenhülse eingeklemmt wird.The device for clamping the thread is located at the end of the bobbin tube 15 on the right in FIG. 3 and is thus opposite to the path of movement of the compensating muzzle thread guide, that is to say the third thread deflection roller 13. The right end 15.1 of the coil sleeve 15 in FIG. 3 is referred to below as the "first end". The known device for clamping the thread is not explained in detail. It is sufficient to note that the thread end is clamped between the centering plate 18.1 and the first end 15.1 of the bobbin tube, as can be seen, for example, from FIG. 4.

Zwischen der Voreilrolle 8 und der ersten Fadenumlenkrolle 12 ist in dem in Fig. 3 im wesentlichen rechts liegenden, dem ersten Ende 15.1 der Spulenhülse gegenüberliegenden Bereich ein ortsfestes Fadenüberlaufblech 19 angeordnet. Dieses Fadenüberlaufblech 19 besitzt eine gekrümmte Oberkante 19.1, die sich im wesentlichen parallel zu den Bewegungsbahnen P4 und P5 der beiden Fadenumlenkrollen 13 und 14 erstreckt und von rechts nach links leicht abfallend ausgebildet ist. Am rechten äußeren Ende 19.11 der Oberkante 19.1 ist eine Fadenführungsrolle 24 angeordnet, die dem ersten Ende 15.1 der Spulenhülse gegenüberliegt und an ihrer Mantelfläche ein Gewinde 24.1 aufweist. Das linke innere Ende 19.12 der Oberkante 19.1 des Fadenüberlaufblechs liegt auf einer Höhe oberhalb der ersten Fadenumlenkrolle 12 und wie aus Fig. 3 zu ersehen gegenüber der ersten Fadenumlenkrolle 12 etwas nach links also in Richtung auf das "zweite Ende" 15.2 der Spulenhülse 15 versetzt.A stationary thread overflow plate 19 is arranged between the lead roller 8 and the first thread deflecting roller 12 in the region lying on the right in FIG. 3 and opposite the first end 15.1 of the bobbin tube. This thread overflow plate 19 has a curved upper edge 19.1 which extends substantially parallel to the movement paths P4 and P5 of the two thread deflecting rollers 13 and 14 and is designed to drop slightly from right to left. At the right outer end 19.11 of the upper edge 19.1 there is a thread guide roller 24 which is opposite the first end 15.1 of the bobbin tube and has a thread 24.1 on its outer surface. The left inner end 19.12 of the upper edge 19.1 of the thread overflow plate lies at a height above the first thread deflection roller 12 and, as can be seen from FIG. 3, in relation to the first thread deflection roller 12 slightly offset to the left in the direction of the "second end" 15.2 of the coil sleeve 15.

Vor der Vorderseite des Fadenüberlaufsblechs 19 ist im Bereich des äußeren Endes 19.11 der Oberkante 19.1 ein hakenartiger Fadenniederhalter 25 angeordnet.In front of the front of the thread overflow plate 19, a hook-type thread retainer 25 is arranged in the area of the outer end 19.11 of the upper edge 19.1.

Wie aus Fig. 3 weiterhin abzulesen, ist im Bereich zwischen der ersten Fadenumlenkrolle 12 und dem zweiten Ende 15.2 der Spulenhülse 15 ein Fadenleitblech 20 angeordnet und zwar so, daß seine Oberkante in einer Ebene liegt, die parallel zur Bewegungsbahn der zweiten und dritten Fadenumlenkrolle 14 bzw. 13 verläuft. An dieser Oberkante befindet sich eine erste Fadenleitkante 20.1, die sich von einem Anfangspunkt im Bereich unterhalb des inneren Endes 19.12 der Oberkante 19.1 des Fadenüberlaufsblechs 19 in Richtung zum zweiten Ende 15.2 der Spulenhülse 15 ansteigend bis zur einer Fadeneinfangkerbe 20.2 erstreckt. Diese Fadeneinfangkerbe ist so angeordnet, daß sie zwischen der ersten Fadenumlenkrolle 12 und dem Endpunkt der Bewegungsbahn der zweiten Fadenumlenkrolle 14 im Bereich des zweiten Endes 15.2 der Spulenhülse 15 liegt. An der Oberkante des Fadenleitblechs 20 ist noch eine zweite Fadenleitkante 20.3 angeordnet, die sich von einem zweiten Anfangspunkt in einem dem zweiten Ende 15.2 der Spulenhülse 15 gegenüberliegenden Bereich in Richtung zum ersten Ende 15.1 der Spulenhülse hin auf einem Teil ihrer Länge ansteigend bis zur Fadeneinfangkerbe 20.2 erstreckt.As can further be seen from FIG. 3, a thread guide plate 20 is arranged in the area between the first thread deflection roller 12 and the second end 15.2 of the bobbin tube 15, specifically in such a way that its upper edge lies in a plane that is parallel to the movement path of the second and third thread deflection roller 14 or 13 runs. On this upper edge there is a first thread leading edge 20.1, which extends from a starting point in the area below the inner end 19.12 of the upper edge 19.1 of the thread overflow plate 19 in the direction of the second end 15.2 of the bobbin tube 15 up to a thread catching notch 20.2. This thread catch notch is arranged such that it lies between the first thread deflection roller 12 and the end point of the path of movement of the second thread deflection roller 14 in the region of the second end 15.2 of the bobbin tube 15. On the upper edge of the thread guide plate 20 there is also a second thread guide edge 20.3, which rises from a second starting point in a region opposite the second end 15.2 of the bobbin tube 15 in the direction of the first end 15.1 of the bobbin tube to part of its length up to the thread capture notch 20.2 extends.

Weiterhin ist an der zweiten Fadenumlenkrolle 14 ein erster Mitnehmer 21 angeordnet, der als in Richtung der Bewegungsbahn auf das zweite Ende 15.2 der Spulenhülse hinweisender Finger ausgebildet ist und einen zu seinem freien Ende in ansteigenden Bereich mit einer Ablaufkante an der Oberseite 21.1 und einer Ablaufkante an der Unterseite 21.2 besitzt. Das innere Ende der Ablaufkante an der Unterseite 21.2 mündet direkt in die zweite Fadenumlenkrolle 14 ein.Furthermore, a first driver 21 is arranged on the second thread deflection roller 14, which as in the direction of the movement path on the second end 15.2 of the coil sleeve pointing finger is formed and has a rising end to its free end with a drain edge on the top 21.1 and a drain edge on the bottom 21.2. The inner end of the trailing edge on the underside 21.2 opens directly into the second thread deflection roller 14.

Weiterhin ist an der Fadenführerstange 14.1 also in Verbindung mit der zweiten Fadenumlenkrolle 14 und zwar in Richtung zum ersten Ende 15.1 der Spulenhülse 15 hin ein zweiter Mitnehmer 22 angeordnet. Dieser zweite Mitnehmer besitzt eine Halterung 22.1 die im wesentlichen als U-förmig gebogenes Blech ausgebildet ist, derart, daß die Ebene des Fadenleitblechs 20 zwischen den Schenkeln dieses nach unten offenen U-förmig gebogenen Bleches verläuft und somit die Halterung auf ihrer Bewegungsbahn die Fadenleitkante 20.1 übergreift. Der eine Schenkel der Halterung ist mit der Fadenführerstange 14.1 verbunden, während der andere Schenkel an der der zweiten Fadenumlenkrolle 14 zugewandten Seite eine rückspringende Ablaufkante 22.3 trägt, und am unteren Ende des Schenkels an der von der zweiten Fadenumlenkrolle 14 abgewandten Seite ein Mitnehmerhaken 22.2 angeordnet ist, der in Richtung seiner Bewegung auf das erste Ende 15.1 der Spulenhülse hin offen ist.Furthermore, a second driver 22 is arranged on the thread guide rod 14.1 in connection with the second thread deflection roller 14, specifically in the direction of the first end 15.1 of the bobbin tube 15. This second driver has a holder 22.1 which is designed essentially as a U-shaped sheet, such that the plane of the thread guide plate 20 runs between the legs of this downwardly open U-shaped plate and thus the holder on its path of movement, the thread guide edge 20.1 spreads. One leg of the holder is connected to the thread guide rod 14.1, while the other leg carries a recessed trailing edge 22.3 on the side facing the second thread deflection roller 14, and a driver hook 22.2 is arranged on the lower end of the leg on the side facing away from the second thread deflection roller 14 , which is open in the direction of its movement towards the first end 15.1 of the coil sleeve.

Die besonderen Bedingungen, die bei der Anordnung des zweiten Mitnehmers 22 im Verhältnis zu der zweiten Fadenumlenkrolle 14 zu beachten sind, werden anhand von Fig. 2a erläutert. Hierbei sind Fig. 2a folgende zusätzliche Bezeichnungen zu entnehmen:
   EP1 = Endpunkt der Bewegungsbahn der zweiten Fadenumlenkrolle 14 an der Seite des ersten Endes 15.1 der Spulenhülse;
   EP2 = Endpunkt der Bewegungsbahn der zweiten Fadenumlenkrolle 14 an der Seite des zweiten Endes 15.2 der Spulenhülse;
   EP3 = Endpunkt der Bewegungsbahn der dritten Fadenumlenkrolle 13 an der Seite des ersten Endes 15.1 der Spulenhülse;
   EP4 = zweiter Endpunkt der Bewegungsbahn der dritten Fadenumlenkrolle 13;
   X = Abstand zwischen Mitnehmerhake 22.2 und der zweiten Fadenumlenkrolle 14;
   Y = Abstand zwischen Endpunkt EP2 und der Fadeneinfangkerbe 20.2;
   Z = Abstand zwischen Endpunkt EP1 und Endpunkt EP3 in Bewegungsrichtung.The special conditions which are to be observed in the arrangement of the second driver 22 in relation to the second thread deflection roller 14 are explained with reference to FIG. 2a. 2a are the following additional designations refer to:
EP1 = end point of the path of movement of the second thread deflection roller 14 on the side of the first end 15.1 of the bobbin tube;
EP2 = end point of the path of movement of the second thread deflection roller 14 on the side of the second end 15.2 of the bobbin tube;
EP3 = end point of the path of movement of the third thread deflection roller 13 on the side of the first end 15.1 of the bobbin tube;
EP4 = second end point of the movement path of the third thread deflection roller 13;
X = distance between the driver hook 22.2 and the second thread deflection roller 14;
Y = distance between end point EP2 and the thread catching notch 20.2;
Z = distance between end point EP1 and end point EP3 in the direction of movement.

Um ein einwandfreies Funktionieren des zweiten Mitnehmers 22 beim Einfädelungsvorgang sicher zu stellen, muß der Abstand X zwischen dem Mitnehmerhaken 22.2 und der zweiten Fadenumlenkrolle 14 kleiner sein als der Abstand Y zwischen der Fadeneinfangkerbe 20.2 und dem Endpunkt EP2 der Bewegungsbahn der zweiten Fadenumlenkrolle 14 aber größer als der Abstand Z zwischen dem Endpunkt EP1 der Bewegungsbahn der zweiten Fadenumlenkrolle 14 und dem Endpunkt EP3 der Bewegungsbahn der dritten Fadenumlenkrolle 13.In order to ensure proper functioning of the second driver 22 during the threading process, the distance X between the driver hook 22.2 and the second thread deflection roller 14 must be smaller than the distance Y between the thread catch notch 20.2 and the end point EP2 of the path of movement of the second thread deflection roller 14 but greater than the distance Z between the end point EP1 of the movement path of the second thread deflection roller 14 and the end point EP3 of the movement path the third thread deflection roller 13.

An der dritten Fadenumlenkrolle 13 ist ein dritter Mitnehmer 23 angeordnet. Dieser Mitnehmer ist Teil einer an der dritten Fadenumlenkrolle 13 angeordneten, sich schnabelartig öffnenden, Fadeneinfangvorrichtung und besitzt einen an der Oberseite der dritten Fadenumlenkrolle 13 angeordneten in Richtung der Bewegungsbahn auf das erste Ende 15.1 der Spulenhülse hinweisenden Finger 23.1, der an der Ober- und Unterseite zum freien Ende hin ansteigende Ablaufkanten aufweist. Dieser dritte Mitnehmer 23 liegt mit seinem Ende im wesentlichen in der Ebene der Bewegungsbahn des Mitnehmerhakens 22.2. Die Ablaufkante an der Unterseite mündet in die dritte Fadenumlenkrolle 13.A third driver 23 is arranged on the third thread deflection roller 13. This driver is part of a beak-like thread trapping device arranged on the third thread deflection roller 13 and has a finger 23.1 on the top and bottom of the third thread deflection roller 13 which points in the direction of the movement path and points to the first end 15.1 of the bobbin tube has draining edges rising towards the free end. The end of this third driver 23 lies essentially in the plane of the path of movement of the driver hook 22.2. The trailing edge on the underside opens into the third thread deflection roller 13.

Es wird nun anhand der Figuren 2a bis 9 der mit der beschriebenen Fadeneinfädeleinrichtung erzeugte Einfädelvorgang erläutert.The threading process generated with the thread threading device described will now be explained with reference to FIGS. 2a to 9.

Das Einfädeln beginnt mit dem in den Figuren 3 und 4 dargestellten Zustand der Vorrichtung. Der in den Figuren 3 und 4 mit F' bzw. F bezeichnete Faden wird durch den Fadenniederhalter 25 und über die Fadenführungsrolle 24 zum ersten Ende 15.1 der Spulenhülse 15 geführt und dort zwischen den Zentrierteller 18.1 und die Spulenhülse 15 eingeklemmt. Dies kann beispielsweise in der Weise geschehen, daß die Spulenhülse 15 von Hand gegen Federkraft verschoben wird zur Erzeugung eines Spaltes zwischen dem Zentrierteller 18.1 und dem Ende 15.1 der Spulenhülse. In diesen Spalt wird das Fadenende FE eingelegt und nach dem Loslassen der Spulenhülse 15 unter der Wirkung der Federkraft eingeklemmt. Mit dem Auflegen der Spulenhülse 15 auf die Friktionsantriebswalze 17 wird der Faden F abgezogen. Das über die Fadenführungsrolle 24 laufenden Fadenstück wird durch das Gewinde 24.1 zum in Fig. 3 und 4 linken Ende der Fadenführungsrolle 24 geführt. Aufgrund dieser Bewegung bildet sich am ersten Ende 15.1 der Spulenhülse eine Fadenreserve. Am linken Ende der Fadenführungsrolle 24 wird der Faden an das äußere Ende 19.11 der Oberkante 19.1 des Fadenüberlaufsblechs 19 übergeben wo er in Pfeilrichtung P5 (Fig. 4) auf der abwärts geneigten Oberkante 19.1 entlangrutscht bis zum inneren Ende 19.12 der Oberkante 19.1. Nach dem Ablaufen des Fadens von der Oberkante 19.1 ist der in Fig. 5 dargestellte Zustand erreicht.The threading begins with the state of the device shown in FIGS. 3 and 4. The thread designated F 'and F in FIGS. 3 and 4 is guided through the thread retainer 25 and over the thread guide roller 24 to the first end 15.1 of the bobbin tube 15 and clamped there between the centering plate 18.1 and the bobbin tube 15. This can be done, for example, in such a way that the coil sleeve 15 is moved by hand against spring force to produce a gap between the centering plate 18.1 and the end 15.1 of the coil sleeve. The thread end FE is inserted into this gap and after the Let go of the bobbin tube 15 clamped under the action of the spring force. When the bobbin tube 15 is placed on the friction drive roller 17, the thread F is drawn off. The thread piece running over the thread guide roller 24 is guided through the thread 24.1 to the left end of the thread guide roller 24 in FIGS. 3 and 4. Due to this movement, a thread reserve forms at the first end 15.1 of the bobbin tube. At the left end of the thread guide roller 24, the thread is transferred to the outer end 19.11 of the upper edge 19.1 of the thread overflow plate 19 where it slides in the direction of the arrow P5 (FIG. 4) on the downwardly inclined upper edge 19.1 to the inner end 19.12 of the upper edge 19.1. After the thread has run from the upper edge 19.1, the state shown in FIG. 5 is reached.

Es ist allerdings nicht unbedingt notwendig, daß es zu einem freien Abrutschen des Fadens auf der Oberkante 19.1 kommt. Wie in Fig. 5 gestrichelt angedeutet, kann der erste Mitnehmer 21 den Faden F' während seiner Bewegung auf der Oberkante 19.1 ergreifen und infolge seiner Bewegung in Pfeilrichtung P7 den Faden in Pfeilrichtung P8 in Richtung der Changierbewegung zwangsläufig mitnehmen. Jedenfalls wird der Faden spätestens in der in Fig. 5 ausgezogen dargestellten Stellung vom ersten Mitnehmer 21 mitgenommen, wobei er an der Ablaufkante 21.2 an der Unterseite entlanggleitet bis in die zweite Fadenumlenkrolle 14 hinein.However, it is not absolutely necessary for the thread to slide freely on the upper edge 19.1. As indicated by dashed lines in FIG. 5, the first driver 21 can grip the thread F 'during its movement on the upper edge 19.1 and, due to its movement in the direction of the arrow P7, inevitably take the thread in the direction of the arrow P8 in the direction of the traversing movement. In any case, the thread is taken along by the first driver 21 at the latest in the position shown in FIG. 5, whereby it slides along the underside of the trailing edge 21.2 into the second thread deflection roller 14.

Der Faden wird von der zweiten Fadenumlenkrolle 14 zwingend auf der Fadenleitkante 20.1 des Fadenleitblechs 20 aufwärts mitgeführt, bis er in die Fadeneinfangkerbe 20.2 gerät. Dieser Zustand ist in Fig. 6 dargestellt.The thread is mandatory by the second thread deflection roller 14 on the thread guide edge 20.1 of the thread guide plate 20 carried upwards until it gets into the thread catch notch 20.2. This state is shown in Fig. 6.

Die zweite Fadenumlenkrolle 14 mit dem ersten Mitnehmer 21 bewegt sich in der gleichen Richtung P9 (Fig. 6) weiter bis zum Endpunkt ihrer Bewegungsbahn, wobei der zweite Mitnehmer 22 mitgeführt wird. Beim Vorbeigang an der Fadeneinfangkerbe 20.2 überläuft der Mitnehmerhaken 22.2 den Faden F' mittels der Ablaufschräge 22.3. Dies ist in Fig. 7 gestrichelt angedeutet. Beim Rücklauf der zweiten Fadenumlenkrolle 14 in Pfeilrichtung P10 und der entsprechenden Bewegung des zweiten Mitnehmers 22 greift der Mitnehmerhaken 22.2 nunmehr unter den Faden F und nimmt ihn in Pfeilrichtung P11 mit, bis er in die erste Fadenumlenkrolle 12 gerät, wobei die an dieser Fadenumlenkrolle angeordnete, sich schnabelartig öffnende Einfangvorrichtung 26, diesen Vorgang unterstützt.The second thread deflection roller 14 with the first driver 21 moves in the same direction P9 (FIG. 6) to the end point of its path of movement, the second driver 22 being carried along. When passing the thread catch notch 20.2, the catch hook 22.2 overflows the thread F 'by means of the bevel 22.3. This is indicated by dashed lines in FIG. 7. When the second thread deflection roller 14 returns in the direction of the arrow P10 and the corresponding movement of the second driver 22, the driver hook 22.2 now engages under the thread F and takes it along in the direction of the arrow P11 until it gets into the first thread deflection roller 12, the arranged on this thread deflection roller 12 beak-like catching device 26 supports this process.

Der weitere Fortgang der Bewegung ist aus Fig. 8 zu entnehmen. Der Faden F läuft nunmehr um die erste Fadenumlenkrolle 12, den Mitnehmerhaken 22.2 und die zweite Fadenumlenkrolle 14. Die vom Mitnehmerhaken 22.2 mitgeführte Fadenschlaufe FS überläuft den an der dritten Fadenumlenkrolle 13 angeordneten dritten Mitnehmer 23.1. Sowohl der zweite Mitnehmer 22 als auch die dritte Fadenumlenkrolle 13 bewegen sich in den Pfeilrichtungen P12 bzw. P13 auf ihre jeweiligen Endpositionen zu (siehe Figur 2a), wie auch in Fig. 8 gestrichelt angedeutet.The further progress of the movement can be seen in FIG. 8. The thread F now runs around the first thread guide roller 12, the driver hook 22.2 and the second thread guide roller 14. The thread loop FS carried by the driver hook 22.2 overflows the third driver 23.1 arranged on the third thread guide roller 13. Both the second driver 22 and the third thread deflecting roller 13 move in the arrow directions P12 and P13 towards their respective end positions (see FIG. 2a), as also indicated by dashed lines in FIG. 8.

In Fig. 9 ist die Situation beim Rücklauf des zweiten Mitnehmers 22 in Pfeilrichtung P14 dargestellt. Die Fadenschlaufe FS wird dabei in der durch FS' angedeuteten Weise durch den dritten Mitnehmer 23.1 aus dem Mitnehmerhaken 22.2 entnommen und unter Einwirkung der Fadeneinfangvorrichtung 23 an der dritten Fadenumlenkrolle 13 in diese eingefädelt. Diese endgültige Situation ist in Fig. 9 ausgezogen dargestellt. Die dritte Fadenumlenkrolle 13 bewegt sich weiter in Pfeilrichtung P15.In Fig. 9 is the situation when the second driver 22 shown in the direction of arrow P14. The thread loop FS is removed in the manner indicated by FS 'by the third driver 23.1 from the driver hook 22.2 and threaded into the third thread deflection roller 13 under the action of the thread catching device 23. This final situation is shown in solid lines in FIG. 9. The third thread deflection roller 13 continues to move in the direction of arrow P15.

Mit der Einfädelung in die dritte Fadenumlenkrolle 13 ist der Einfädelvorgang beendet. Der Faden F verläuft nunmehr wie aus Fig. 9 zu entnehmen genau in der Weise wie es in Fig. 3 dargestellt ist.With the threading into the third thread deflection roller 13, the threading process is ended. The thread F now runs as shown in FIG. 9 exactly in the manner as shown in FIG. 3.

Wie der Funktionsablauf zeigt, ergibt sich die oben erläuterte Bedingung für den Abstand des zweiten Mitnehmers 22 von der zweiten Umlenkrolle 14 dadurch, daß einerseits in der Endposition EP2 der zweiten Fadenumlenkrolle 14 (Fig. 2 a) der Mitnehmerhaken 22.2 die Fadeneinfangkerbe 20.2 passiert haben muß (Fig. 7) und andererseits in den Endpositionen EP1 bzw. EP3 der zweiten Fadenumlenkrolle 14 und der dritten Fadenumlenkrolle 13 der Mitnehmerhaken 22.2 die dritte Fadenumlenkrolle 13 soweit überlaufen haben muß, daß beim Rücklauf die Fadenschlaufe vom dritten Mitnehmer 23.1 übernommen werden kann (Fig. 8, 9).As the functional sequence shows, the above-mentioned condition for the distance of the second driver 22 from the second deflection roller 14 results from the fact that, on the one hand, in the end position EP2 of the second thread deflection roller 14 (FIG. 2 a), the driver hook 22.2 must have passed the thread catch notch 20.2 (Fig. 7) and on the other hand, in the end positions EP1 and EP3 of the second thread deflection roller 14 and the third thread deflection roller 13 of the catch hooks 22.2, the third thread deflection roller 13 must have overrun so far that the thread loop can be taken over by the third catch 23.1 during the return (FIG. 8, 9).

Die oben beschriebene Einfädeleinrichtung ermöglicht nicht nur die Neuanlage eines Fadens auf eine leere Spulenhülse sondern auch ein Wiederanlegen nach einem Fadenbruch. Es ist dann auch möglich, den Faden am zweiten Ende 15.2 der Spulenhülse oder in der Nähe dieses Endes anzulegen und den automatischen Einfädelvorgang einzuleiten, der dann unter Benutzung der zweiten Fadenleitkante 20.3 abläuft. Wie in den Zeichnungen nicht eigens dargestellt aber z.B. aus Fig. 3 und Fig. 5 bis 7 ohne weiteres zu erkennen, wird ein am zweiten Ende 15.2 angelegter Faden zunächst unmittelbar vom Hauptchangierfadenführer 14.2 ergriffen und in Richtung auf das erste Ende 15.1 der Spulenhülse mitgeführt. Dabei wird der Faden über die zweite Fadenleitkante 20.3 mitgenommen, bis er in die Fadeneinfangkerbe 20.2 gelangt. Aus dieser Fadeneinfangkerbe wird er vom Hauptchangierfadenführer 14.2 wieder herausgezogen und auf der ersten Fadenleitkante 20.1 mitgeführt, wobei er aber die erste Fadenumlenkrolle 12 nicht überlaufen kann. Beim nächsten Changierhub, der vom ersten Ende 15.1 zum zweiten Ende 15.2 der Spulenhülse verläuft, ergibt sich nun wieder der bereits beschriebene automatische Einfädelvorgang.The threading device described above not only makes it possible to create a new thread on an empty bobbin tube but also to put it back on after a thread break. It is then also possible put the thread on the second end 15.2 of the bobbin tube or in the vicinity of this end and initiate the automatic threading process which then takes place using the second thread guide edge 20.3. As not specifically shown in the drawings, but easily recognizable, for example, from FIGS. 3 and 5 to 7, a thread placed at the second end 15.2 is first gripped directly by the main traversing thread guide 14.2 and carried in the direction of the first end 15.1 of the bobbin tube. The thread is carried along via the second thread guide edge 20.3 until it reaches the thread catch notch 20.2. It is pulled out of this thread catch notch by the main traversing thread guide 14.2 and carried along on the first thread guide edge 20.1, but it cannot overflow the first thread deflection roller 12. With the next traverse stroke, which runs from the first end 15.1 to the second end 15.2 of the bobbin tube, the automatic threading process already described is again obtained.

Aus dem beschriebenen Funktionsablauf geht hervor, daß beim Einfädelvorgang eine Reihe eng beieinander stehender Bauteile sich in Relativbewegung gegeneinander befinden. Es hat sich daher aus Sicherheitsgründen als zweckmäßig erwiesen, wenn wie in Fig. 10 dargestellt der Bereich der Fadeneinfädeleinrichtung mit einem Abdeckblech 27 abgedeckt ist. Dieses Abdeckblech 27 befindet sich zweckmäßigerweise zwischen der Voreilrolle 8 und dem Hauptchangierfadenführer 14.2 und ist so ausgestaltet, daß es sich oberhalb der Fadenumlenkrollen 12, 13 und 14 befindet aber den Bereich des Fadenniederhalters 25 und der Fadenführungsrolle 24 freiläßt, damit der oben beschriebene Arbeitsgang, bei dem der Faden unter dem Fadenniederhalter 25 und über die Fadenführungsrolle 24 geführt wird und zwischen dem Zentrierteller 18.1 und dem Ende 15.1 der Spulenhülse eingeklemmt wird, ungestört möglich ist. Nach dem Beginn des eigentlichen Einfädelvorgangs unterläuft der Faden das Abdeckblech 27. Das Abdeckblech 27 kann, um ein Beobachten des Einfädelvorgangs zu ermöglichen, aus durchsichtigem Material bestehen.The functional sequence described shows that a number of closely spaced components are in relative movement to one another during the threading process. For safety reasons, it has therefore proven to be expedient if, as shown in FIG. 10, the area of the thread threading device is covered with a cover plate 27. This cover plate 27 is expediently located between the lead roller 8 and the main traversing thread guide 14.2 and is designed such that it is above the thread deflecting rollers 12, 13 and 14 but the area of the thread retainer 25 and the thread guide roller 24 leaves free, so that the above-described operation, in which the thread is guided under the thread retainer 25 and over the thread guide roller 24 and is clamped between the centering plate 18.1 and the end 15.1 of the bobbin tube, is possible undisturbed. After the start of the actual threading process, the thread runs under the cover plate 27. The cover plate 27 can be made of transparent material in order to enable the threading process to be observed.
