Abstract

A bobbin winder, for cross wound bobbins has a splicer to join the upper and lower yarns. A sensor detects the upper yarn, and a suction nozzle is operated by an electro-motor for positioning the suction opening at the surface of with winding bobbin and at the splicer. An electro-motor drive (25) for the suction nozzle (12) is given a defined reversing movement through a winding station computer (39). The sensor (35) to register the correct pick-up of the upper yarn (34), is also connected to the winding station computer. The winding station computer, on receipt of a negative signal from the sensor, gives a multiple and short reversal of the motor direction, to give a pitching movement to the suction nozzle (38) at the surface (48) of the winding bobbin (11).

Description

Die Erfindung betrifft ein Spulaggregat einer Kreuzspulen herstellenden Textilmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a winding unit of a cheese manufacturing textile machine according to the preamble of Claim 1.

Derartige Spulaggregate sind beispielsweise durch die japanische Offenlegungsschrift Hei 5-246 626 bekannt.Such winding units are, for example, by the Japanese laid-open publication Hei 5-246 626.

In dieser Schrift ist ein Spulaggregat für einen Kreuzspulautomaten beschrieben, das eine über einen zugehörigen Einzelantrieb definiert verschwenkbare Saugdüse aufweist, wobei innerhalb der Saugdüse eine Sensoreinrichtung zum Detektieren eines aufgenommenen Oberfadens installiert ist. Außerdem ist die maximale Suchzeit, d.h., die Zeit während der die Saugdüse an der Oberfläche einer Auflaufspule positioniert bleibt, über ein Zeitglied einstellbar.
Wenn innerhalb der vorgegebenen Suchzeit durch die Sensoreinrichtung kein Fadenende festgestellt wird, wird die Fadensuche und damit der Fadenverbindungsversuch abgebrochen.This document describes a winding unit for an automatic winder which has a suction nozzle which can be pivoted in a defined manner via an associated individual drive, a sensor device for detecting a picked up upper thread being installed within the suction nozzle. In addition, the maximum search time, ie the time during which the suction nozzle remains positioned on the surface of a package, can be set using a timer.
If the end of the thread is not detected by the sensor device within the specified search time, the thread search and thus the thread connection attempt is terminated.

Die DE 42 31 958 A1 beschreibt ein Spulaggregat mit einer Fadenverbindungseinrichtung, die ein schwenkbar gelagertes Multifunktions-Fadenhandhabungselement besitzt. Mit diesem Fadenhandhabungselement kann sowohl der Oberfaden als auch der Unterfaden in eine Spleißeinrichtung eingelegt werden. Wahrend das Fadenhandhabungselement den Unterfaden direkt aufnimmt, erfolgt die Aufnahme des Oberfadens indirekt über eine zusätzliche Flachdüse. An diese Flachdüse ist das Fadenhandhabungselement zur Fadenübernahme andockbar.
Die Flachdüse ist mit einem Motor verbunden, der die Flachdüse während des Spulprozesses so verschwenkt, daß die Düsenmündung im Bereich der Auflaufspulenoberfläche verbleibt. Durch entsprechende Ansteuerung dieses Motors ist es außerdem möglich, den Abstand der Mündung der Flachdüse zur Auflaufspulenoberfläche zu variieren.DE 42 31 958 A1 describes a winding unit with a thread connecting device which has a pivotably mounted multifunctional thread handling element. With this thread handling element, both the upper thread and the lower thread can be inserted into a splicing device. While the thread handling element takes up the lower thread directly, the upper thread is picked up indirectly via an additional flat nozzle. The thread handling element for thread takeover can be docked onto this flat nozzle.
The flat nozzle is connected to a motor which pivots the flat nozzle during the winding process so that the nozzle mouth remains in the area of the package surface. By appropriate control of this motor, it is also possible to vary the distance from the mouth of the flat nozzle to the surface of the package.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die bekannten Spulaggregate für Kreuzspulen herstellende Textilmaschinen weiter zu verbessern.Starting from the aforementioned prior art, the Invention the object of the known winding units for To further improve cross-wound textile machines.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved by a device solved, as described in claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Subclaims.

Durch die erfindungsgemäße Ausbildung der Saugdüse ist gewährleistet, daß Fadenschlingen, die sich im Bereich der Saugdüsenmündung, insbesondere an dem in diesem Bereich angeordneten Nadelkamm festsetzen können und dann das ordnungsgemäße Einsaugen des Fadenendes des Oberfadens in die Saugdüse behindern, zuverlässig aufgelöst werden.Due to the inventive design of the suction nozzle ensures that thread loops that are in the area of Suction nozzle mouth, especially on the in this area can arrange arranged comb and then that proper suction of the thread end of the upper thread into the Obstruct suction nozzle, be resolved reliably.

Derartige Fadenschlingen, die besonders bei haarigen Garnen auftreten, werden durch die Nickbewegungen der Saugdüse aufgelöst. Das heißt, der sich durch die Nickbewegung der Saugdüse immer wieder von der Oberfläche der Auflaufspule wegbewegte Nadelkamm zieht eventuelle Fadenschlingen in Richtung des Fadenendes und löst diese dadurch auf.
Die Nickbewegungen der Saugdüse werden dabei durch entsprechende Ansteuerung eines mit der Saugdüse verbundenen, reversierbaren Antriebes erzeugt. Der Antrieb wird dabei vom Spulstellenrechner in Abhängigkeit von einem 'Negativ-Signal' der in die Saugdüse integrierten Sensoreinrichtung initiiert. Das heißt, wenn die Sensoreinrichtung keinen Fadenanfang detektiert, wird der reversierbare Antrieb eingeschaltet.Thread loops of this type, which occur particularly in hairy yarns, are released by the pitching movements of the suction nozzle. This means that the needle comb, which is constantly moved away from the surface of the package by the pitching movement of the suction nozzle, pulls any thread loops in the direction of the thread end and thereby dissolves them.
The pitching movements of the suction nozzle are generated by appropriate control of a reversible drive connected to the suction nozzle. The drive is initiated by the winding unit computer as a function of a 'negative signal' from the sensor device integrated in the suction nozzle. This means that if the sensor device does not detect the start of a thread, the reversible drive is switched on.

In bevorzugter Ausführungsform ist die Sensoreinrichtung, wie im Anspruch 2 dargelegt, als optischer Fadensensor ausgebildet, der, wie üblich, über eine Lichtquelle sowie ein fotoelektrisches Empfängerteil, zum Beispiel einen Fototransistor, eine Fotodiode oder einen Fotowiderstand, verfügt. Bei derartigen beispielsweise durch die DE-OS 21 23 641 bekannten Sensoreinrichtungen führt ein sich in den Bereich zwischen Lichtquelle und Empfängerteil erstreckendes Fadenende zu einer Abschattung auf dem Empfängerteil. Diese Abschattung wird im Empfängerteil in ein elektrisches Signal umgesetzt, das über eine Signalleitung an den Spulstellenrechner weitergegeben wird.
Wenn der Spulstellenrechner nicht innerhalb einer vorbestimmten Zeitspanne, während der die Saugdüsenmündung im Bereich der Auflaufspulenoberfläche positioniert ist, ein solches Signal erhält, wird das Ausbleiben eines derartigen Signals vom Spulstellenrechner dahingehend bewertet, daß der Oberfaden entweder nicht aufgenommen werden konnte oder, was insbesondere bei haarigen Garnen vorkommt, nicht vorschriftsmäßig, d.h, als Fadenschlinge aufgenommen wurde und diese Fadenschlinge jetzt im Nadelkamm der Saugdüsenmündung festliegt.
Der Spulstellenrechner reagiert auf dieses 'Negativ Signal' der Sensoreinrichtung durch Ansteuern des reversierbaren Antiebes.In a preferred embodiment, as set out in claim 2, the sensor device is designed as an optical thread sensor which, as usual, has a light source and a photoelectric receiver part, for example a photo transistor, a photo diode or a photo resistor. In such sensor devices known, for example, from DE-OS 21 23 641, a thread end extending into the area between the light source and the receiver part leads to shadowing on the receiver part. This shading is converted into an electrical signal in the receiver section, which is passed on to the winding station computer via a signal line.
If the winding station computer does not receive such a signal within a predetermined period of time during which the suction nozzle mouth is positioned in the area of the package surface, the absence of such a signal is evaluated by the winding station computer in such a way that the upper thread either could not be picked up or, particularly in the case of hairy ones Yarn occurs, not in accordance with regulations, ie when the thread loop was taken up and this thread loop is now fixed in the needle comb of the suction nozzle mouth.
The winding unit computer reacts to this 'negative signal' from the sensor device by actuating the reversible drive.

Wie im Anspruch 3 beschrieben, ist in weiterer Ausgestaltung der Erfindung vorgesehen, daß die Saugdüse über ein Kurvenscheibengetriebe mit dem reversierbaren Antrieb verbunden ist. Die Kurvenscheibe weist dabei eine Führungskontur auf, die es ermöglicht, die Kurvenscheibe sowohl im Uhrzeigersinn als auch im Gegenuhrzeigersinn zu drehen. Das bedeutet, ein mit einer Laufrolle auf der Führungskontur der Kurvenscheibe aufliegender Kurvenhebel, der zum Beispiel über ein Zahnsegment mit einem entsprechenden Zahnkranz an der Saugdüse verbunden ist, kann durch Reversieren des Antriebes auf- und abbewegt werden, was sich als Nickbewegungen auf die Saugdüse überträgt. Eine derartig gestaltete Einrichtung kann über die Vorgabe des Drehwinkels des Antriebes nicht nur sehr exakt verschwenkt werden, sondern zeichnet sich auch durch eine große Zuverläßigkeit und eine hohe Lebensdauer aus.As described in claim 3, is in a further embodiment the invention provided that the suction nozzle over a Cam gear connected to the reversible drive is. The cam disc has a guide contour that it allows the cam to turn both clockwise and also turn counterclockwise. That means a with a roller on the guide contour of the cam overlying cam lever, for example over a tooth segment connected to a corresponding ring gear on the suction nozzle can be moved up and down by reversing the drive what is transferred to the suction nozzle as pitching movements. A device designed in this way can be specified by the Angle of rotation of the drive not only pivoted very precisely but is also characterized by a large Reliability and a long service life.

In vorteilhafter Ausgestaltung kann, wie im Anspruch 4 dargelegt, die Verweildauer während der die Saugdüsenmündung jeweils im Bereich der Auflaufoberfläche positioniert ist, über den Spulstellenrechner eingestellt werden. Das heißt, durch entsprechendes Anpassen der Stopp-Zeiten des reversierbaren Antriebes auf die gegebenen Spulbedingungen, insbesondere unter Berücksichtigung des vorliegenden Garnmaterials, ist es möglich, die für die Oberfadenaufnahme benötigte Zeit zu minimieren, was sich positiv auf die Dauer des Fadenverbindungsvorganges auswirkt und damit zu einer weiteren Verbesserung des Wirkungsgrades des Kreuzspulautomaten führt.In an advantageous embodiment, as in claim 4 set out the length of time during which the suction nozzle orifice is positioned in the area of the overrun surface, respectively the winding unit computer can be set. That is, through corresponding adjustment of the stop times of the reversible Drive on the given winding conditions, especially under Taking into account the present yarn material, it is possible, the time required for the upper thread take up minimize what's positive in the long run Thread connection process affects and thus to another Improves the efficiency of the automatic winder.

Weitere Einzelheiten der Erfindung sind einem nachfolgend anhand der Zeichnungen erläuterten Ausführungsbeispiel entnehmbar.Further details of the invention are as follows exemplary embodiment explained with reference to the drawings removable.

Solche Kreuzspulautomaten weisen üblicherweise eine Vielzahl gleichartiger Spulaggregate 2 auf. Auf diesen Spulaggregaten 2 werden die auf einer (nicht dargestellten) Ringspinnmaschine produzierten Spinnkopse 9 zu großvolumigen Auflaufspule, sogenannten Kreuzspulen 11, umgespult. Die fertiggestellten Kreuzspulen 11 werden mittels eines selbsttätig arbeitenden Serviceaggregates auf eine Kreuzspulentransporteinrichtung 21 ausgerollt und anschließend zu einer maschinenendseitig angeordneten (nicht dargestellten) Spulenverladestation oder dergleichen transportiert.Such automatic winding machines usually have a large number similar winding units 2. On these winding units 2 are on a ring spinning machine (not shown) produced spinning bobbins 9 to large-volume package, so-called cross-wound bobbins 11, rewound. The completed ones Cross-wound bobbins 11 are operated automatically Service unit on a package transport device 21 rolled out and then to a machine end side arranged (not shown) coil loading station or the like transported.

Solche Kreuzspulautomaten 1 weisen in der Regel außerdem eine Logistikeinrichtung in Form eines Spulen- und Hülsentransportsystemes 3 auf. In diesem Spulen- und Hülsentransportsystem 3 laufen, auf Transporttellern 8, Spinnkopse 9 beziehungsweise Leerhülsen 20 um. Von diesem umfangreichen Transportsystem 3 sind in den Figuren 1 und 2 lediglich die maschinenlange Kopszuführstrecke 4, die hinter den Spulaggregaten 2 verlaufende Reversierstrecke 5, eine der zu den Spulaggregaten 2 führenden Quertransportstrecken 6 sowie die Hülsenrückführstrecke 7 dargestellt.Such automatic winder 1 usually also have a Logistics facility in the form of a coil and Sleeve transport system 3. In this coil and Sleeve transport system 3 run, on transport plates 8, Spinning heads 9 or empty tubes 20 um. Of this extensive transport system 3 are shown in FIGS. 1 and 2 only the machine-long cop feed path 4, which is behind the winding units 2 running reversing section 5, one of the to the winding units 2 leading transverse transport routes 6 and the sleeve return path 7 shown.

Die angelieferten Spinnkopse 9 werden in den Abspulstellungen 10, die sich im Bereich der Quertransportstrecken 6 befinden, zu Kreuzspulen 11 umgespult. Die einzelnen Spulaggregate 2 verfügen dabei über verschiedene, an sich bekannte Einrichtungen, die einen ordnungsgemäßen Betrieb dieser Arbeitsstellen gewährleisten. The delivered spinning heads 9 are in the Unwind positions 10, which are in the range of Cross transport routes 6 are located, rewound into cross-wound bobbins 11. The individual winding units 2 have different, known facilities that have a proper Ensure the operation of these jobs.

In der Figur 1 ist mit 30 der vom Spinnkops 9 zur Kreuzspule 11 laufende Faden, mit 12 eine Saugdüse, mit 22 ein Greiferrohr, mit 13 eine Spleißeinrichtung, mit 14 eine Fadenspanneinrichtung, mit 15 ein Fadenreiniger mit Fadenschneideinrichtung sowie mit 16 eine Paraffiniereinrichtung angedeutet. Die Spulenantriebstrommel, die die Kreuzspule 11 während des Spulvorganges über Reibschluß in Richtung des Pfeiles 23 antreibt, trägt die Bezugszahl 17. Während des Spulvorganges ist die Kreuzspule 11 in einem Spulenrahmen 18 gehalten, der um eine Achse 19 schwenkbar gelagert ist. Unterhalb des Spulenrahmens 18 ist, ebenfalls um eine Schwenkachse 19 begrenzt drehbar, ein Schwenkblech angeordnet, über das die fertigen Kreuzspulen 11 auf die hinter den Spulaggregaten 2 angeordnete Kreuzspulentransporteinrichtung 21 überführt werden können.In FIG. 1, at 30 is that of the spinning cop 9 to the cheese 11 running thread, with 12 a suction nozzle, with 22 a hook tube, at 13 a splicer, at 14 one Thread tensioning device, with 15 a thread cleaner with Thread cutting device as well as 16 one Paraffinizing device indicated. The coil drive drum, the cheese 11 during the winding process via friction drives in the direction of arrow 23, bears the reference number 17th During the winding process, the cheese 11 is in one Coil frame 18 held, which is pivotable about an axis 19 is stored. Below the coil frame 18 is also around a pivot axis 19 rotatable to a limited extent, a pivot plate arranged, over which the finished cheese 11 on the rear the winding units 2 arranged Cross-wound bobbin transport device 21 can be transferred.

Wie vorstehend bereits kurz angedeutet, werden die Spulaggregate 2 über ein Serviceaggregat, einen sogenannten Kreuzspulenwechsler, versorgt. Dieser Kreuzspulenwechsler sorgt dafür, daß Kreuzspulen 11, die einen vorbestimmten Durchmesser erreicht haben, auf die Kreuzspulentransporteinrichtung 21 ausgetragen werden und daß anschließend aus einem Leerhülsenmagazin jeweils eine Leerhülse in den Spulenrahmen 18 eingewechselt wird.As already briefly indicated above, the Winding units 2 via a service unit, a so-called Cross-wound bobbin changer, supplied. This package changer ensures ensure that cross-wound bobbins 11 which have a predetermined diameter have reached, on the bobbin transport device 21st be carried out and that then from a Empty tube magazine each have an empty tube in the coil frame 18 is exchanged.

Die Fig. 2 zeigt die Situation an einem Spulaggregat 2 bei einer Spulunterbrechung. Zu einer solchen Spulunterbrechung kann es beispielsweise kommen, wenn der Fadenreiniger 15 aufgrund eines festgestellten Fadenfehlers den laufenden Faden 30 gekappt hat. In diesem Fall läuft der Oberfaden 34 auf die Oberfläche 48 der Kreuzspule 11 auf, während der Unterfaden 33 in der Regel im Fadenspanner 14 geklemmt und für den nachfolgenden Fadenverbindungsvorgang bereit gehalten wird. 2 shows the situation on a winding unit 2 a winding interruption. Such an interruption in the winding it can happen, for example, if the thread cleaner 15 due to a detected thread fault the current Thread 30 has cut. In this case, the upper thread 34 runs open the surface 48 of the bobbin 11, while the bobbin thread 33 usually clamped in the thread tensioner 14 and for the subsequent thread connection process is kept ready.

In Figur 2 ist der Zeitpunkt zu Beginn des Fadenverbindungsvorganges dargestellt.In Figure 2, the time at the beginning of Thread connection process shown.

Funktion der Einrichtung:Function of the facility:

Wenn es während des normalen Spulprozesses, der in Fig. 1 dargestellt ist, zu einer Spulunterbrechung kommt, weil beispielsweise der Faden gebrochen ist oder weil der den laufenden Faden 30 überwachende Fadenreiniger 15 einen unzulässigen Fadenfehler erkannt und daraufhin seine Fadenschneideinrichtung aktiviert hat, wird in der Regel der Unterfaden 33 im Fadenspanner 14 geklemmt und dort für den nachfolgenden Fadenverbindungsvorgang bereitgehalten.
Der Oberfaden 34, der im Falle eines Fadenschnittes auch den Fadenfehler aufweist, läuft dagegen auf die Oberfläche 48 der Auflaufspule 11 auf, die von der Antriebswalze 17 abgehoben und in den Stillstand abgebremst wird.If a winding interruption occurs during the normal winding process, which is shown in FIG. 1, because, for example, the thread is broken or because the thread cleaner 15 monitoring the running thread 30 has recognized an impermissible thread error and has subsequently activated its thread cutting device, the As a rule, the lower thread 33 is clamped in the thread tensioner 14 and kept there ready for the subsequent thread connection process.
The upper thread 34, which also has the thread defect in the event of a thread cut, runs onto the surface 48 of the package 11, which is lifted off the drive roller 17 and braked to a standstill.

Zur Aufnahme des auf die Oberfläche 48 der Auflaufspule 11 aufgelaufenen Oberfadens 34, wird die Saugdüse 12 aus der in Fig. 1 angedeuteten Ausgangsstellung entlang des Kreisbogens 36 in eine Stellung geschwenkt, in der die Saugdüsenmündung 38 im Bereich der Oberfläche 48 der Auflaufspule 11, die langsam in Abwickelrichtung 24 gedreht wird, positioniert ist. Die Saugdüse 12 verharrt im Normalfall eine kurze Zeitspanne (0,5 bis 1 Sek.) in dieser Position und schwenkt anschließend, nachdem die in die Saugsdüse 12 integrierte Sensoreinrichtung 35 den angesaugten Fadenanfang 49 des Oberfadens 34 detektiert hat, in ihre untere Ausgangsstellung zurück. Der Oberfaden 34 wird dabei in die Speißeinrichtung 13 eingelegt.For receiving the on the surface 48 of the package 11 accumulated upper thread 34, the suction nozzle 12 from the in 1 indicated starting position along the circular arc 36 pivoted into a position in which the suction nozzle 38 in Area of the surface 48 of the package 11 that slowly enters Unwinding direction 24 is rotated, is positioned. The Suction nozzle 12 normally remains for a short time (0.5 up to 1 sec.) in this position and then swivels, after the sensor device integrated in the suction nozzle 12 35 detects the sucked thread beginning 49 of the upper thread 34 has to return to its lower starting position. The upper thread 34 is inserted into the feed device 13.

Anschließend wird der Unterfaden 33 durch das pneumatisch beaufschlagbare Greiferrohr 22 ebenfalls in die Spleißeinrichtung 13 eingelegt. Das Greiferrohr 22 schwenkt dabei entlang des Kreisbogens 37 aus seiner Ausgangsstellung in die in Fig. 2 gestrichelt dargestellte Fadeneinlagestellung. Das erfolgreiche Einlegen des Unterfadens 33 in die Spleißeinrichtung 13 kann durch einen (nicht dargestellten) Unterfadensensor überwacht werden.Then the lower thread 33 is pneumatic actable gripper tube 22 also in the Splice device 13 inserted. The gripper tube 22 pivots thereby along the circular arc 37 from its initial position in the thread insertion position shown in dashed lines in FIG. 2. The successful insertion of the lower thread 33 in the Splicing device 13 can by a (not shown) Bobbin thread sensor are monitored.

In der Speißeinrichtung 13 wird der Oberfaden 34, nach dem Ausreinigen eines eventuellen Fadenfehlers, mit dem Unterfaden 33 verbunden.In the feeding device 13, the upper thread 34, after the Cleaning out a possible thread defect with the bobbin thread 33 connected.

Wenn der Oberfaden 34 in einer vorgebbaren Zeitspanne durch die Saugdüse 12 nicht oder nicht ordnungsgemäß erfaßt werden konnte, und entsprechend von der Sensoreinrichtung 35 kein Signal an den Spulstellenrechner 39 ergangen ist, wird über die Steuerleitung 32 der reversierbare Antrieb 25 derart angesteuert, daß die Saugdüse 12 Nickbewegungen V,Z ausführt. Das heißt, der Antrieb 25 dreht das Kurvenscheibenpaket 26 und damit die Kurvenscheibe 27 vor und zurück, so daß der Kurvenhebel 39, der mit seiner Laufrolle 43 auf der Führungskontur 44 der Kurvenscheibe 27 aufliegt, auf- und abbewegt wird. Dieses Auf- und Abbewegen des Kurvenhebels 39 überträgt sich als Nickbewegungen V, Z auf die Saugdüse 12.If the upper thread 34 passes through the Suction nozzle 12 can not be detected or not properly could, and accordingly from the sensor device 35 none Signal to the winding station computer 39 has been sent, via the Control line 32 of the reversible drive 25 in this way controlled that the suction nozzle 12 executes pitching movements V, Z. That is, the drive 25 rotates the cam disk package 26 and so that the cam disc 27 back and forth, so that the Cam lever 39, which with its roller 43 on the Guide contour 44 of the cam disc 27 rests on and is moved. This up and down movement of the cam lever 39 transfers as pitching movements V, Z to the suction nozzle 12.

Durch die Nickbewegungen der Saugdüse 12 und damit auch der Saugdüsenmündung 38 werden Fadenschlingen oder dergleichen, die sich eventuell in dem im Bereich der Saugdüsenmündung 38 angeordneten (nicht dargestellten) Nadelkamm verfangen haben, aufgezogen und das Fadenende 49 des Oberfadens 34 vorschriftsmäßig in die Saugdüse 12 eingesaugt.Due to the pitching movements of the suction nozzle 12 and thus the Suction nozzle mouth 38 become thread loops or the like possibly in the area of the suction nozzle mouth 38 caught (not shown) arranged needle comb, wound and the thread end 49 of the upper thread 34 correctly sucked into the suction nozzle 12.
