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 the claim 1. Such a winding device is described in DE 2 711 024 C2 described.

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 thread is continuously a winding device located at each spinning or Zwimpstelle delivered and there usually wound into a cheese. In order for that continuous processing of cheeses a Anknotmöglichkeit in shape to create a reserve of thread and the cheese uninterrupted until the last Winding off, the thread reserve should consist of a thread that the same spinning or twisting twist as the total wound to the cheese Thread has.

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 apply a thread to an empty one Coil sleeve and the formation of the thread reserve largely automated to perform on the one hand to relieve the operator and on the other hand Consistent, reproducible results even for successive winding operations to obtain.

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 by means of a Gripper arm brought in the vicinity of a perforated bobbin tube. about a suction line running in the coil frame arm and on the front side of the centering plate arranged openings is through the centering plate through air sucked off the bobbin tube. Due to the outside through the holes of the bobbin tube nachströmenden air is the thread beginning in the interior of the Sucked in bobbin tube and held there, so that the subsequent thread at Rotation of the bobbin tube can be wound on this. Since in the bobbin tube sucked thread beginning within the bobbin tube through the suction air essentially only loosely held, there is no defined Abbindestelle trailing, woven or twisted thread, which ensures that that when forming a thread reserve this has a spinning or twisting twist, the corresponds exactly to that of the wound to the cheese winding thread. apart thereof, this document does not describe measures for building 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 is based on the object, a largely automated working Device for winding up first a thread reserve and then a cross-wound bobbin on a bobbin tube according to the preamble of the claim 1 to be designed so that the wound up to a thread reserve thread a Rotation, the rotation of the wound to the cheese winding thread equivalent.

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

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 hollow centering plate axis, to which a suction head can be adjusted is, an exact threadline is ensured in the direction of the suction source, so that by means arranged within the suction device for clamping And cutting the thread can be ensured that the means of Clamping device held thread end a well-defined spinning or Twisted twisting has. To with this thread beginning the necessary thread reserve to be able to wind up, is in the area of the centering plate outside the traversing path the traversing yarn guide arranged a retaining member, preferably from a position leading the thread in the direction of the centering plate in a thread releasing position is adjustable.

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 running through the centering plate Suction channel can be either by hand or automated by means of known Thread feeding devices take place.

    • 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.From a generally e.g. from DE 27 11 024 C2 known coil frame is in Figures 1 - 3 only one coil frame arm 1 shown, which is a hollow axle 2 carries. On this hollow shaft 2 is a centering plate 4 by means of the bearing 3 mounted, the at least one of its outer circumference extending radially inwardly Suction channel 4.1 has. 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. Of the Friction drive roller 6 is in the direction of the double arrow f2 back and forth associated movable traversing yarn guide 7. FIG. 1 also shows a yarn delivery system 8 and a usual advance role 9.

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

    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 towards the centering plate 4 annular chamber 11.1, in which a displaceable in the axial direction back and forth Suction nozzle 12 is mounted, which at its free end a sealing ring 13th carries, which can be brought against the edge of the cylinder housing 10 to the plant. At the suction nozzle 12 is followed by a channel 11.2 a chamber 14, in the a leading to a compressed air injector 15 suction channel 16 opens. Upon admission the Druckluftinjektors 15 with compressed air is in the direction of Arrows f3 effective Saugluftströmung generated, with the attached to a suction 4.1 the centering plate 4 applied end of the thread sucked through the suction head A as long or is pulled through until it is ensured that the thread end is 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, is within the chamber 14th a first clamping member 17 is mounted stationary against the, as in Figure 2 is shown, a second, movable clamping member 18 for clamping the Thread is adjustable. The second clamping member 18 is at a against the force of a Return spring 19 adjustable cylinder 20 attached, in which a cutting knife 31 supporting, against the force of a return spring 21 adjustable piston 22 is guided. The piston 22 associated with the return spring 19 is supported its end at an internal annular shoulder of the cylinder 20 from. The cylinder 20 associated return spring 21 is supported at one end to an outer Ring shoulder of this cylinder 20 from. The cylinder 20 is in turn in one Outer cylinder 23 slidably guided, the for the application of the piston 22nd Compressed air through a line 24 can be fed. The cylinder 20 is open Ground provided.

    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 as 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 in clamping position against the first clamping member 17th is brought to the plant, before then the separating knife 31 carrying Piston 22 is moved into the cylinder 20 to the between the two Separate clamping members 17/18 with the clamped thread.

    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 Cylinder chamber 25 provided in the one against the force of a return spring 26 displaceable piston 27 is housed. On the piston 27 is a on a Driving pin 12.1 of the suction 12 attached attacking 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 is outside the traversing path of the traversing yarn guide 7 a thread retaining member 32 is arranged, which consists of a thread in Direction of the centering plate 4 guiding position (see Figure 1) in a thread releasing position (see Figure 3) is adjustable. This thread retaining member 32 is mounted in a manner only schematically illustrated on a holder 33, a Part of the otherwise not shown machine frame forms.

    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 with Compressed air is applied to the suction nozzle 12 via the driving pin 12.1 in Direction of the centering plate to move until the sealing ring 13 against the edge of the Cylinder housing 10 comes to the plant. Then the compressed air injector 15 pressurized with compressed air, so that one to the outlet opening of the suction channel 4.1 effective suction flow is generated, whereby a to this suction channel 4.1 held thread end is sucked off until at least in the area Suction head chamber 14, a thread with the desired rotation is present. Of the Thread is thereby by means of the retaining member 32 outside the traversing path held the traversing yarn guide 7. After that, 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 Coil sleeve 5 on the friction drive roller 6 is by pressurizing the piston 22 of the thread between the two clamping members 17/18 clamped and by means of the separating knife 31 in the direction of the compressed air injector 15th cut through. The fed through the suction, not the required Rotation having thread can be either centrally or on the spindle in one Thread remnants are collected.

    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 between the clamping members 17/18 clamped thread becomes a multi-layered tube when the bobbin is rotating Thread reserve FR wound, which at the same time the thread reserve is fixed as soon as a sufficient thread reserve 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 clamped is 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 yarn guide moving back and forth and is in common Way to be wound into a cheese. With increasing winding diameter the cheese is the Spulenrahmenarm 1 in the represented by the arrow f4 Way swung, causing the 17/18 of the clamping members released thread end is pulled out of the suction head. Because the thread is no longer clamped, a free rotation of the thread beginning in the sleeve axis, d. H. 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.
