Description

Die Erfindung betrifft eine Aufwickelvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1. Eine derartige Aufwickelvorrichtung ist in der DE 2 711 024 C2 beschrieben.The invention relates to a winding device according to the preamble of claim 1. Such a winding device is described in DE 2 711 024 C2.

Bei Textilmaschinen, beispielsweise Spinn- und Zwirnmaschinen, wird der Faden kontinuierlich einer an jeder Spinn- oder Zwimstelle befindlichen Spuleinrichtung angeliefert und dort in der Regel zu einer Kreuzspule aufgewickelt. Um für das kontinuierliche Verarbeiten von Kreuzspulen eine Anknotmöglichkeit in Form einer Fadenreserve zu schaffen und die Kreuzspule störungsfrei bis zur letzten Windung abzuziehen, soll die Fadenreserve aus einem Faden bestehen, der die gleiche Spinn- oder Zwirndrehung wie der zur Kreuzspule insgesamt aufgewickelte Faden hat.In textile machines, such as spinning and twisting machines, the yarn is continuously supplied to a winding device located at each spinning or Zwimstelle and there usually wound into a cross-wound bobbin. In order to create a Anknotmöglichkeit in the form of a thread reserve for the continuous processing of cheeses and deduct the cheese uninterrupted until the last turn, the thread reserve should consist of a thread that has the same spinning or twisting as the yarn to the cheese wound in total.

Eine weitere Forderung besteht darin, das Anlegen eines Fadens auf eine leere Spulenhülse und die Bildung der Fadenreserve weitgehend automatisiert durchzuführen, um einerseits das Bedienungspersonal zu entlasten und andererseits auch für aufeinanderfolgende Spulvorgänge gleichbleibende, reproduzierbare Ergebnisse zu erhalten.Another requirement is to carry out the application of a thread on an empty bobbin tube and the formation of the thread reserve largely automated, on the one hand to relieve the operator and on the other hand to obtain consistent, reproducible results for successive winding operations.

Bei der Vorrichtung gemäß DE 2 711 024 C2 wird der Fadenanfang mittels eines Greiferarms in die Nähe einer mit Löchern versehenen Spulenhülse gebracht. Über eine im Spulenrahmenarm verlaufende Saugleitung und an der Stirnseite des Zentriertellers angeordnete Öffnungen wird durch den Zentrierteller hindurch Luft aus der Spulenhülse abgesaugt. Aufgrund der von außen durch die Löcher der Spulenhülse nachströmenden Luft wird der Fadenanfang in den Innenraum der Spulenhülse eingesaugt und dort festgehalten, so daß der nachfolgende Faden bei Rotation der Spulenhülse auf diese aufgewickelt werden kann. Da der in die Spulenhülse eingesaugte Fadenanfang innerhalb der Spulenhülse durch die Saugluft im wesentlichen nur locker festgehalten wird, liegt keine definierte Abbindestelle des nachlaufenden, gesponnenen oder gezwirnten Fadens vor, die gewährleistet, daß bei Bildung einer Fadenreserve diese eine Spinn- oder Zwirndrehung hat, die derjenigen des zur Kreuzspule aufgewickelten Fadens genau entspricht. Abgesehen davon, beschreibt diese Druckschrift keine Maßnahmen zum Aufbau einer Fadenreserve.In the apparatus according to DE 2 711 024 C2, the thread beginning is brought by means of a gripper arm in the vicinity of a provided with holes bobbin tube. Via a suction line extending in the coil frame arm and openings arranged on the front side of the centering plate, air is sucked out of the bobbin tube through the centering plate. Due to the air flowing in from the outside through the holes of the bobbin tube, the beginning of the thread is sucked into the interior of the bobbin tube and held there, so that the following thread can be wound onto it upon rotation of the bobbin tube. Since the sucked into the bobbin thread beginning within the bobbin tube is held by the suction air essentially only loosely, there is no defined Abbindestelle the trailing, spun or twisted yarn, which ensures that when forming a thread reserve this has a spinning or twisting, the corresponds exactly to that of the wound to the cheese winding thread. Apart from that, this document does not describe any measures to build up a thread reserve.

Der Erfindung liegt die Aufgabe zugrunde, eine weitgehend automatisiert arbeitende Vorrichtung zum Aufwickeln von zuerst einer Fadenreserve und anschließend einer Kreuzspule auf eine Spulenhülse gemäß dem Oberbegriff des Patentanspruchs 1 so zu gestalten, daß der zu einer Fadenreserve aufgewickelte Faden eine Drehung aufweist, die der Drehung des zur Kreuzspule aufgewickelten Fadens entspricht.The invention has for its object to design a largely automated device for winding first a reserve of thread and then a cheese on a bobbin tube according to the preamble of claim 1 so that the wound up to a thread reserve thread has a rotation of the rotation of the corresponds to the cross wound coil wound thread.

Zur Lösung dieser Aufgabe dienen die Merkmale des Kennzeichens des Patentanspruchs 1.To solve this problem, the features of the characterizing part of claim 1 serve.

Dadurch, daß der Zentrierteller einen radial nach innen gerichteten Saugkanal aufweist, der in eine Zentriertellerhohlachse mündet, an die ein Saugkopf anstellbar ist, ist ein exakter Fadenlauf in Richtung zur Saugquelle gewährleistet, so daß mittels der innerhalb des Saugkopfes angeordneten Einrichtungen zum Festklemmen und Schneiden des Fadens sichergestellt werden kann, daß das mittels der Klemmeinrichtung festgehaltene Fadenende eine genau definierte Spinn- bzw. Zwirndrehung hat. Um mit diesem Fadenanfang die notwendige Fadenreserve aufwickeln zu können, ist im Bereich des Zentriertellers außerhalb des Changierweges des Changierfadenführers ein Rückhalteorgan angeordnet, das vorzugsweise aus einer den Faden in Richtung des Zentriertellers führenden Position in eine den Faden freigebende Position verstellbar ist.Characterized in that the centering plate has a radially inwardly directed suction channel, which opens into a centering plate hollow axis, to which a suction head is adjustable, an exact yarn path is ensured in the direction of the suction source, so that means arranged within the suction head means for clamping and cutting the Thread can be ensured that the held by means of the clamping device yarn end has a well-defined spinning or twisting. In order to be able to wind up the necessary thread reserve with this thread beginning, a retaining member is arranged in the region of the centering outside the traverse path of the traversing yarn guide, which is preferably adjustable from a position leading the thread in the direction of the centering plate in a position releasing the thread.

Das Anlegen des Fadens an die Saugöffnung des durch den Zentrierteller verlaufenden Saugkanals kann entweder von Hand oder automatisiert mittels bekannter Fadenanlegevorrichtungen erfolgen.The application of the thread to the suction opening of the suction channel running through the centering plate can be done either manually or automatically by means of known yarn feeding devices.

Bevorzugte Ausgestaltungen der Erfindung sind in Unteransprüchen behandelt.Preferred embodiments of the invention are dealt with in subclaims.

Die Erfindung wird im folgenden anhand der Zeichnungen näher beschrieben.

  • Figur 2 zeigt den Zustand nach dem Festklemmen und Durchtrennen des in den Saugkopf eingesaugten Fadens, und
  • Figur 3 zeigt den Betriebszustand während des Aufwickelns der Kreuzspule.
The invention will be described in more detail below with reference to the drawings.
  • Figure 1 shows a detail of one arm of a creel with attached thereto centering plate and employed to the centering plate suction during the suction of the thread;
  • Figure 2 shows the state after the clamping and cutting of the suctioned into the suction head, and
  • FIG. 3 shows the operating state during the winding of the cross-wound bobbin.

Von einem generell z.B. aus der DE 27 11 024 C2 bekannten Spulenrahmen ist in den Figuren 1 - 3 nur der eine Spulenrahmenarm 1 dargestellt, der eine Hohlachse 2 trägt. Auf dieser Hohlachse 2 ist mittels des Lagers 3 ein Zentrierteller 4 gelagert, der mindestens einen von seinem Außenumfang radial nach innen verlaufenden Saugkanal 4.1 aufweist. Jeder Saugkanal mündet in die Hohlachse 2. Auf den Zentrierteller 4 ist eine Spulenhülse 5 aufgesteckt, die mittels einer in Richtung des Pfeiles f1 antreibbaren Friktionsantriebswalze 6 antreibbar ist. Der Friktionsantriebswalze 6 ist ein in Richtung des Doppelpfeiles f2 hin und her bewegbarer Changierfadenführer 7 zugeordnet. Figur 1 zeigt weiterhin ein Fadenlieferwerk 8 und eine übliche Voreilrolle 9.Of a generally known for example from DE 27 11 024 C2 creel is shown in Figures 1 - 3, only the one Spulenrahmenarm 1, which carries a hollow shaft 2. On this hollow axle 2, a centering plate 4 is mounted by means of the bearing 3, which has at least one of its outer circumference radially inwardly extending suction channel 4.1. Each suction channel opens into the hollow axle 2. On the centering plate 4, a bobbin tube 5 is attached, which by means of a in Direction of the arrow f1 drivable friction drive roller 6 can be driven. The friction drive roller 6 is associated with a traversing thread guide 7 which can be moved back and forth in the direction of the double arrow f2. FIG. 1 further shows a yarn delivery mechanism 8 and a conventional advance pulley 9.

Die Hohlachse 2 mündet in ein an seiner äußeren Stirnseite im wesentlichen offenes Zylindergehäuse 10.The hollow axle 2 opens into a cylinder housing 10, which is essentially open at its outer end side.

Seitlich neben dem Spulenrahmenarm 1 ist ein Saugkopf A angeordnet. Der Saugkopf A hat ein Gehäuse 11, das eine in Richtung zum Zentrierteller 4 offene Ringkammer 11.1 aufweist, in der ein in axialer Richtung hin und her verschiebbarer Saugstutzen 12 gelagert ist, der an seinem freien Ende einen Dichtungsring 13 trägt, der gegen den Rand des Zylindergehäuses 10 zur Anlage bringbar ist. An den Saugstutzen 12 schließt sich über einen Kanal 11.2 eine Kammer 14 an, in die ein zu einem Druckluftinjektor 15 führender Saugkanal 16 mündet. Bei Beaufschlagung des Druckluftinjektors 15 mit Druckluft wird eine in Richtung des Pfeiles f3 wirksame Saugluftströmung erzeugt, mit der das an einen Saugkanal 4.1 des Zentriertellers 4 angelegte Fadenende durch den Saugkopf A solange eingesaugt bzw. durchgezogen wird, bis sichergestellt ist, daß das Fadenende etwa im Bereich der Kammer 14 eine ordnungsgemäß, genau definierte Drehung hat.Laterally next to the Spulenrahmenarm 1 a suction head A is arranged. The suction head A has a housing 11 which has an open toward the centering plate 4 annular chamber 11.1, in which an axially displaceable back and forth suction nozzle 12 is mounted, which carries at its free end a sealing ring 13 which against the edge of Cylinder housing 10 can be brought to the plant. To the suction nozzle 12 is followed by a channel 11.2 a chamber 14, in which a leading to a Druckluftinjektor 15 suction channel 16 opens. Upon application of compressed air injector 15 with compressed air in the direction of the arrow f3 effective suction air flow is generated, with the applied to a suction channel 4.1 of the centering 4 thread end as long as sucked or pulled through the suction head A until it is ensured that the thread end approximately in Area of the chamber 14 has a properly, well-defined rotation.

Um das Fadenende in diesem Zustand zu fixieren, ist innerhalb der Kammer 14 ein erstes Klemmorgan 17 stationär angebracht, gegen das, so wie es in Figur 2 dargestellt ist, ein zweites, bewegliches Klemmorgan 18 zum Festklemmen des Fadens anstellbar ist. Das zweite Klemmorgan 18 ist an einem gegen die Kraft einer Rückstellfeder 19 verstellbaren Zylinder 20 befestigt, in dem ein ein Trennmesser 31 tragender, gegen die Kraft einer Rückstellfeder 21 verstellbarer Kolben 22 geführt ist. Die dem Kolben 22 zugeordnete Rückstellfeder 19 stützt sich mit ihrem Ende an einer internen Ringschulter des Zylinders 20 ab. Die dem Zylinder 20 zugeordnete Rückstellfeder 21 stützt sich mit ihrem einen Ende an einer äußeren Ringschulter dieses Zylinders 20 ab. Der Zylinder 20 ist seinerseits in einem Außenzylinder 23 verschiebbar geführt, dem zur Beaufschlagung des Kolbens 22 Druckluft durch eine Leitung 24 zuführbar ist. Der Zylinder 20 ist mit einem offenen Boden versehen.In order to fix the thread end in this state, a first clamping member 17 is stationarily mounted within the chamber 14, against which, as shown in Figure 2, a second, movable clamping member 18 for clamping the thread is adjustable. The second clamping member 18 is fixed to a cylinder 20 which is adjustable against the force of a return spring 19 and in which a piston 22 carrying a separating blade 31 and movable against the force of a return spring 21 is guided. The return spring 19 assigned to the piston 22 is supported at its end on an internal annular shoulder of the cylinder 20. The cylinder 20 associated with the return spring 21 is supported at one end to an outer annular shoulder of this cylinder 20 from. The cylinder 20 is in turn displaceably guided in an outer cylinder 23, which is for acting on the piston 22nd Compressed air through a line 24 can be fed. The cylinder 20 is provided with an open bottom.

Die dem Kolben 22 zugeordnete Rückstellfeder 19 hat eine höhere Federsteifigkeit als die dem Zylinder 20 zugeordnete Rückstellfeder 21 derart, daß bei Beaufschlagung des Kolbens 22 mit Druckluft zuerst das an dem Zylinder 20 angebrachte zweite Klemmorgan 18 in Klemmstellung gegen das erste Klemmorgan 17 zur Anlage gebracht wird, bevor anschließend der das Trennmesser 31 tragende Kolben 22 in den Zylinder 20 eingefahren wird, um den zwischen den beiden Klemmorganen 17/18 festgeklemmten Faden durchzutrennen.The piston 22 associated with the return spring 19 has a higher spring stiffness than the cylinder 20 associated return spring 21 such that upon application of the piston 22 with compressed air first attached to the cylinder 20 second clamping member 18 is brought into clamping position against the first clamping member 17 to the plant before subsequently the piston 22 carrying the separating knife 31 is retracted into the cylinder 20 in order to sever the thread clamped between the two clamping members 17/18.

Das Gehäuse 11 ist weiterhin mit einer einen Druckluftanschluß 25.1 aufweisenden Zylinderkammer 25 versehen, in der ein gegen die Kraft einer Rückstellfeder 26 verschiebbarer Kolben 27 untergebracht ist. An dem Kolben 27 ist eine an einem Mitnehmerzapfen 12.1 des Saugstutzens 12 angreifende Kolbenstange befestigt.The housing 11 is further provided with a compressed air connection 25.1 having a cylinder chamber 25 in which a displaceable against the force of a return spring 26 piston 27 is housed. On the piston 27 is attached to a driving pin 12.1 of the suction nozzle 12 engaging piston rod.

Im Bereich des Zentriertellers 4 ist außerhalb des Changierweges des Changierfadenführers 7 ein Fadenrückhalteorgan 32 angeordnet, das aus einer den Faden in Richtung des Zentriertellers 4 lenkenden Position (s. Figur 1) in eine den Faden freigebende Position (s. Figur 3) verstellbar ist. Dieses Fadenrückhalteorgan 32 ist in nur schematisch dargestellter Weise an einer Halterung 33 angebracht, die einen Teil des ansonsten nicht dargestellten Maschinenrahmens bildet.In the region of the centering plate 4, outside the traverse path of the traversing yarn guide 7, there is arranged a yarn restraining member 32 which is adjustable from a position (see Figure 1) guiding the yarn in the direction of the centering plate 4 to a position releasing the yarn (see Figure 3). This thread retaining member 32 is mounted in a manner only schematically illustrated on a holder 33 which forms a part of the otherwise not shown machine frame.

Zur Übergabe eines Fadens an eine leere Spulhülse 5 wird der Kolben 27 mit Druckluft beaufschlagt, um den Saugstutzen 12 über den Mitnehmerzapfen 12.1 in Richtung des Zentriertellers zu bewegen, bis der Dichtring 13 gegen den Rand des Zylindergehäuses 10 zur Anlage kommt. Anschließend wird der Druckluftinjektor 15 mit Druckluft beaufschlagt, so daß eine bis zur Ausgangsöffnung des Saugkanales 4.1 wirksame Saugströmung erzeugt wird, wodurch ein an diesen Saugkanal 4.1 gehaltenes Fadenende so lange abgesaugt wird, bis mindestens im Bereich der Saugkopfkammer 14 ein Faden mit der gewünschten Drehung vorhanden ist. Der Faden wird dabei mittels des Rückhalteorgans 32 außerhalb des Changierweges des Changierfadenführers 7 gehalten. Danach wird der Spulenrahmen abgesenkt, bis die Spulenhülse auf der laufenden Friktionsantriebswalze 6 aufliegt, wodurch die Spulenhülse in Drehung versetzt wird. Gleichzeitig mit dem Absenken der Spulenhülse 5 auf die Friktionsantriebswalze 6 wird durch Druckluftbeaufschlagung des Kolbens 22 der Faden zwischen den beiden Klemmorganen 17/18 festgeklemmt und mittels des Trennmessers 31 in Richtung zum Druckluftinjektor 15 hin durchgetrennt. Der durch das Absaugen eingezogene, nicht die erforderliche Drehung aufweisende Faden kann entweder zentral oder an der Spindel in einem Fadenrestbehälter gesammelt werden.To transfer a thread to an empty winding tube 5, the piston 27 is acted upon by compressed air to move the suction nozzle 12 via the driving pin 12.1 in the direction of the centering plate until the sealing ring 13 comes to bear against the edge of the cylinder housing 10. Subsequently, the compressed air injector 15 is acted upon by compressed air, so that an effective suction flow to the output opening of the suction 4.1 is generated, whereby a held on this suction channel 4.1 yarn end is sucked off until at least in the region of the suction chamber 14 a thread with the desired rotation available is. The thread is thereby by means of the retaining member 32 outside the traversing path held the traversing yarn guide 7. Thereafter, the bobbin frame is lowered until the bobbin tube rests on the current friction drive roller 6, whereby the bobbin tube is rotated. Simultaneously with the lowering of the bobbin tube 5 on the friction drive roller 6, the thread between the two clamping members 17/18 is clamped by Druckluftbeaufschlagung of the piston 22 and cut by means of the separating blade 31 in the direction of the Druckluftinjektor 15 out. The drawn through the suction, not having the required rotation having thread can be collected either centrally or on the spindle in a thread waste container.

Der mittels des Fadenrückhalteorgans 32 geführte und zwischen den Klemmorganen 17/18 festgeklemmte Faden wird bei rotierender Spulenhülse zu einer mehrlagigen Fadenreserve FR aufgewickelt, wodurch gleichzeitig die Fadenreserve fixiert wird, sobald eine ausreichende Fadenreserve aufgewickelt worden ist.The guided by means of the thread retaining member 32 and clamped between the clamping members 17/18 thread is wound with a rotating bobbin tube to a multilayer reserve of thread FR, whereby at the same time the thread reserve is fixed as soon as a sufficient reserve of thread has been wound up.

Danach kann die Wickelbildung auf der Hülse erfolgen, da der Faden geklemmt ist und die erforderliche Wickelspannung vorliegt.Thereafter, the winding can be done on the sleeve, since the thread is clamped and the required winding tension is present.

Nach Freigabe des Fadens durch das Fadenrückhalteorgan 32 fällt der Faden in den sich hin und her bewegenden Changierfadenführer ein und wird in üblicher Weise zu einer Kreuzspule gewickelt werden. Bei anwachsendem Wickeldurchmesser der Kreuzspule wird der Spulenrahmenarm 1 in der durch den Pfeil f4 repräsentierten Weise hochgeschwenkt, wodurch das von den Klemmorganen 17/18 freigegebene Fadenende aus dem Saugkopf herausgezogen wird. Da der Faden nicht mehr geklemmt ist, kann ein freies Drehen des Fadenanfangs in der Hülsenachse, d. h. der Hohlachse 2, erfolgen. Der Saugstutzen 12 und der Klemm-Schneide-Kolben 22 werden nun zurückgefahren und der Injektor wird ausgeschaltet.After release of the thread by the thread retaining member 32, the thread falls in the reciprocating traversing yarn guide and will be wound in the usual way to a cross-wound bobbin. With an increasing winding diameter of the cross-wound bobbin frame arm 1 is pivoted up in the manner represented by the arrow f4, whereby the released from the clamping members 17/18 thread end is pulled out of the suction head. Since the thread is no longer clamped, a free rotation of the thread beginning in the sleeve axis, ie the hollow shaft 2, take place. The suction nozzle 12 and the clamping cutting piston 22 are now moved back and the injector is turned off.
