Abstract

A textile machine has a parallel upright bobbin (S) winding station with a thread feed unit (5). The empty bobbins are lifted and transported to the winding station where they are wound on a turntable holder (9) with individual retaining sockets for each bobbin. The turntable has a power unit to position bobbins in the wind-on position. The turntable socket consists of a countersunk section for the bobbin flange and a central aperture for the bobbin core. The bobbin wind-up action is generated by a drive wheel in contact with the bobbin rim and step motor. The bobbins are wound in series, a full bobbin being replaced by a waiting bobbin on the turntable.

Description

Die vorliegende Erfindung betrifft einen automatischen Spulenwechsler für einen Parallelspulautomaten, auf welchem Randscheibenspulen an einer Spulstation von einem Fadenverlegeaggregat bespult werden, wobei die Randscheibenspulen auf eine Spulenaufnahme aufgesetzt, an die Spulstation transportiert und in vertikaler Lage bespult werden.The present invention relates to an automatic bobbin changer for a parallel automatic winder on which edge disc coils are spooled on a winding station by a yarn laying unit, wherein the edge disc coils placed on a bobbin, transported to the winding station and bespult in a vertical position.

Bei einem bekannten Parallelspulautomaten dieser Art, dem AP-Winder der Firma Hacoba, ist die Spulenaufnahme durch eine schräge Rutsche gebildet, auf der die leeren Spulen zur Spulstation rutschen und die vollen Spulen bis zu ihrer Abnahme verbleiben. Dieses System erlaubt keinen sicheren Nachschub der Leerhülsen, da dieser stark von der Reibung zwischen Spule und Rutsche abhängt. Ausserdem neigen die Vollspulen zum Kippen auf der schrägen Rutsche, und die zur Vermeidung von Beschädigungen der Spulenoberfläche erforderliche Separation der Spulen an der Spulstation kann nur mit erheblichem mechanischem Aufwand realisiert werden.In a known Parallelspulautomaten this type, the AP-Winder Hacoba, the coil holder is formed by an oblique chute on which the empty coils slip to the winding station and the full coils remain until their removal. This system does not allow a safe supply of empty tubes, as this strongly depends on the friction between the coil and slide. In addition, the full bobbins tend to tilt on the sloping chute, and the required to avoid damage to the coil surface separation of the coils at the winding station can be realized only with considerable mechanical effort.

Durch die Erfindung soll nun ein Spulenwechsler für einen Parallelspulautomaten angegeben werden, der einen sicheren Nachschub der leeren Spulen an die Spulstation und eine Spulenseparation mit einfachen Mitteln ermöglicht und das Kippen der Vollspulen verhindert.The invention will now be given a bobbin changer for a parallel winder, which allows a safe supply of empty bobbins to the winding station and a coil separation with simple means and prevents the tilting of the full bobbins.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Spulenaufnahme durch einen Drehteller gebildet ist, welcher getrennte Aufnahmepositionen für mehrere Spulen und einen Antrieb für die Positionierung der zu bespulenden Spule in der Spulstation aufweist.This object is achieved according to the invention in that the bobbin receptacle is formed by a turntable which has separate receiving positions for several bobbins and a drive for positioning the bobbin to be spooled in the winding station.

Beim erfindungsgemässen Spulenwechsler werden die leeren Spulen nicht durch rutschen auf einer schrägen Rutsche sondern durch Rotation des Drehtellers an die Spulstation befördert, wobei die Spulen durch die getrennten Aufnahmepositionen des Drehtellers schon separiert sind und nicht mehr separiert werden müssen. Eine Gefahr des Kippens der vollen Spulen besteht nicht mehr, weil der Drehteller keine schräge, sondern eine horizontale Lage aufweist.When the bobbin changer according to the invention, the empty bobbins are not transported by slipping on a sloping chute but by rotation of the turntable to the winding station, the coils are already separated by the separate receiving positions of the turntable and no longer need to be separated. A risk of tilting the full bobbin is no longer because the turntable has no oblique, but a horizontal position.

Eine erste bevorzugte Ausführungsform des erfindungsgemässen Spulenwechslers ist dadurch gekennzeichnet, dass der Drehteller an den Aufnahmepositionen erste Durchbrechungen für den Durchgriff des unteren Teils einer zur Fixierung der Spule in der Spulstation vorgesehenen Spulenhalterung aufweist.A first preferred embodiment of the inventive bobbin changer is characterized in that the turntable has at the receiving positions first openings for the passage of the lower part of a provided for fixing the coil in the winding station coil holder.

Eine zweite bevorzugte Ausführungsform ist dadurch gekennzeichnet, dass der Antrieb des Drehtellers durch ein an dessen Umfang angreifendes Reibrad gebildet ist. Das Reibrad ist vorzugsweise durch einen Schrittmotor antreibbar.A second preferred embodiment is characterized in that the drive of the turntable is formed by a frictional wheel engaging on its circumference. The friction wheel is preferably driven by a stepper motor.

Eine dritte bevorzugte Ausführungsform ist gekennzeichnet durch einen Sensor zur Erfassung der Drehposition des Drehtellers. Dieser Sensor ist vorzugsweise durch einen Reedkontakt gebildet.A third preferred embodiment is characterized by a sensor for detecting the rotational position of the turntable. This sensor is preferably formed by a reed contact.

Eine vierte bevorzugte Ausführungsform des erfindungsgemässen Spulenwechslers ist gekennzeichnet durch eine auf dem Drehteller auswechselbar befestigte Zentrierscheibe mit an den Aufnahmepositionen vorgesehenen zweiten Durchbrechungen oder Vertiefungen, deren Durchmesser dem Durchmesser der Randscheiben der Spulen entspricht.A fourth preferred embodiment of the bobbin changer according to the invention is characterized by a centrally mounted on the turntable centering disc provided with the receiving positions second openings or recesses whose diameter corresponds to the diameter of the edge discs of the coils.

Eine fünfte bevorzugte Ausführungsform des erfindungsgemässen Spulenwechslers ist gekennzeichnet durch Mittel zur Arretierung des Drehtellers in ausgewählten Drehpositionen, welche durch eine am Rand jeder ersten Durchbrechung vorgesehene rillenförmige Ausbuchtung und einen in diese einrastbaren Arretierstift gebildet sind.A fifth preferred embodiment of the inventive bobbin changer is characterized by means for locking the turntable in selected rotational positions, which are formed by a provided at the edge of each first opening groove-shaped bulge and a latchable in this locking pin.

Eine weitere bevorzugte Ausführungsform ist dadurch gekennzeichnet, dass nach Abschluss des Spulvorgangs durch Herstellung einer vollen Spule in der Spulstation eine Drehbewegung des Drehtellers um eine Teilung bis zur nächsten Aufnahmeposition erfolgt. Vorzugsweise wird der Abschluss des Spulvorgangs in der Spulstation von der Maschinensteuerung anhand der aufgespulten Garnlänge oder des aktuellen Spulendurchmessers berechnet.A further preferred embodiment is characterized in that after completion of the winding process by producing a full bobbin in the winding station a rotational movement of the turntable takes place by a division to the next picking position. The completion of the winding process in the winding station is preferably calculated by the machine control on the basis of the wound yarn length or the current package diameter.

Eine weitere bevorzugte Ausführungsform ist gekennzeichnet durch einen Vollspulensensor für die Abstellung der Maschine, wenn auf dem Drehteller keine leere Spule mehr vorhanden ist.A further preferred embodiment is characterized by a full coil sensor for the shutdown of the machine when no empty coil is present on the turntable.

Die in Fig. 1 dargestellte Spulstation besteht im wesentlichen aus einem Aluminiumprofil 1 mit einem im Bereich von dessen oberem Ende angeordneten Motor 2 für den Antrieb einer Spule S beim Spulvorgang, einer aus einem oberen Teil 3 und einem unteren Teil 4 bestehenden Einrichtung für die Fixierung der Spule S in der Spulstation und einer seitlich am Aluminiumprofil 1 befestigten Fadenverlegung 5. Die Fadenverlegung 5 ist von der in der EP-A-1 209 114 beschriebenen Art und umfasst einen Fadenführer F, der mit einem über Umlenkrollen 6, 7 laufenden, flexiblen, motorisch antreibbaren Changierelement 8 verbunden ist und eine Changierbewegung in Längsrichtung der Spule S, also in vertikaler Richtung, ausführt. Die Umlenkrolle 6 ist als Treibrad für den Antrieb des Changierelements 8 und die Umlenkrolle 7 ist als Vorspannorgan für den Ausgleich von Spannungsschwankungen des Changierelements ausgebildet. Bezüglich weiterer Einzelheiten der Fadenverlegung 5 wird auf die EP-A-1 209 114 verwiesen, auf deren Offenbarung hiermit ausdrücklich Bezug genommen wird.In the Fig. 1 shown winding station consists essentially of an aluminum profile 1 with a arranged in the region of the upper end of the motor 2 for driving a coil S during the winding process, consisting of an upper part 3 and a lower part 4 means for fixing the coil S in the Winding station and a laterally attached to the aluminum profile 1 thread laying 5. The thread laying 5 is of the in the EP-A-1 209 114 described type and includes a yarn guide F, which is connected to a deflection rollers 6, 7 running, flexible, motor driven traversing element 8 and a traversing movement in the longitudinal direction of the coil S, ie in the vertical direction, executes. The guide roller 6 is as a drive wheel for the drive of the traversing element 8 and the guide roller 7 designed as a biasing member for the compensation of voltage fluctuations of the traversing element. For further details of the thread laying 5 is on the EP-A-1 209 114 referenced, the disclosure of which is hereby incorporated by reference.

Der Spulstation ist ein in Fig. 2 detaillierter dargestellter Spulenwechsler zugeordnet, der im wesentlichen einen motorisch antreibbaren karussellartigen Drehteller 9 aufweist, der auf einer drehbaren Achsscheibe 10 befestigt ist. Der Drehteller 9 und die Achsscheibe 10 sowie weitere Komponenten des Spulenwechslers sind auf einem auf dem Spulautomaten befestigten plattenartigen Karussellhalter 11 montiert. Der Antrieb des Drehtellers erfolgt durch ein von einem Schrittmotor 12 angetriebenes Reibrad 13, welches am Umfang des Drehtellers 9 angreift. Der Schrittmotor 12 ist auf einem mit dem Karussellhalter 11 verbundenen Motorträger 22 montiert.The winding station is a in Fig. 2 assigned in more detail bobbin changer having substantially a motor-driven carousel-like turntable 9, which is mounted on a rotatable axle 10. The turntable 9 and the axle 10 and other components of the bobbin changer are mounted on a plate-like carousel holder 11 mounted on the automatic winder. The drive of the turntable is effected by a driven by a stepper motor 12 friction wheel 13 which engages the circumference of the turntable 9. The stepper motor 12 is mounted on a motor support 22 connected to the carousel holder 11.

Der Drehteller 9 weist mehrere, darstellungsgemäss vier, Aufnahmepositionen für Spulen S auf; Die Zentrierung der in Fig. 2 strichpunktiert eingezeichneten Spulen an den Aufnahmepositionen erfolgt durch eine an der Oberseite des Drehtellers 9 auswechselbar befestigte Zentrierscheibe 14, die an den Aufnahmepositionen Vertiefungen oder Abstufungen 15 aufweist, deren Durchmesser dem Durchmesser der Randscheiben 16 der Spulen S entspricht und welche die Aufnahmepositionen definieren. Je nach Durchmesser der Randscheiben 16 werden verschiedene Zentrierscheiben 14 verwendet, wobei, wie aus den Figuren ersichtlich, Randscheiben 16 mit grossem Durchmesser über den Rand des Drehtellers 9 und der Zentrierscheibe 14 seitlich hinausragen können. Die Vertiefungen 15 der Zentrierscheibe 14 sind in diesem Fall keine vollständigen Kreise, so dass die Zentrierscheibe 14 etwa die Form eines Malteserkreuzes hat.The turntable 9 has a plurality, as shown four, receiving positions for coils S; The centering of in Fig. 2 Spotted dotted coils at the receiving positions carried by a mounted on the top of the turntable 9 interchangeable centering 14, which has recesses or steps 15 at the receiving positions, whose diameter corresponds to the diameter of the edge discs 16 of the coil S and which define the receiving positions. Depending on the diameter of the edge discs 16 different centering 14 are used, which, as can be seen from the figures, edge discs 16 with a large diameter over the edge of the turntable 9 and the centering 14 can protrude laterally. The depressions 15 of the centering disc 14 are in this case no complete circles, so that the centering disc 14 has approximately the shape of a Maltese cross.

Der Drehteller 9 hat an jeder Aufnahmeposition eine erste Bohrung 17, die für den Durchgriff des unteren Teils 4 der Einrichtung zur Fixierung der Spulen S in der Spulstation vorgesehen ist. Jede der ersten Bohrungen 17 weist am Rand eine rillenförmige Ausbuchtung 18 auf, die zum Einrasten eines federnd gelagerten Arretierstifts 19 vorgesehen ist. Jede Position des Drehtellers 9 wird einzeln durch einen auf dem Karussellhalter 11 angeordneten Sensor 20 erfasst. Dieser ist ein Reedkontakt, der durch eine neben jeder ersten Bohrung 17 vorgesehene zweite Bohrung 21 betätigt wird. Die dargestellte Ausbildung des Drehtellers 9 mit vier Aufnahmepositionen ist nur beispielhaft zu verstehen, selbstverständlich könnten bei Verwendung von Spulen S mit kleineren Randscheiben 16 auch mehr als vier Aufnahmepositionen vorgesehen sein.The turntable 9 has at each receiving position, a first bore 17 which is provided for the passage of the lower part 4 of the means for fixing the coil S in the winding station. Each of the first holes 17 has at the edge of a groove-shaped recess 18 which is provided for engaging a spring-mounted locking pin 19. Each position of the turntable 9 is detected individually by a sensor 20 arranged on the carousel holder 11. This is a reed contact, which is actuated by a next to each first bore 17 provided second bore 21. The illustrated embodiment of the turntable 9 with four receiving positions is to be understood only as an example, of course, could be provided when using coils S with smaller marginal discs 16 more than four receiving positions.

Im Betrieb des Spulautomaten werden leere Spulen S in die Vertiefungen 15 der Zentrierscheibe 14 auf dem Drehteller 9 gestellt, der durch das Reibrad 13 im Gegenuhrzeigersinn (von oben gesehen) antreibbar ist. Wenn sich an der Spulstation keine Spule S befindet oder gerade eine Spule voll bespult ist, wird der Drehteller 9 um eine Teilung gedreht und die nächste leere Spule S an die Spulstelle transportiert.In operation, the automatic winder empty coils S are placed in the recesses 15 of the centering disc 14 on the turntable 9, which is driven by the friction wheel 13 in the counterclockwise direction (seen from above). If there is no spool S at the winding station, or if a spool is currently fully spooled, the turntable 9 is rotated by one pitch and the next empty spool S is transported to the winding station.

Die Beendigung des Spulvorgangs erkennt der Spulautomat anhand der aufgespulten Garnlänge, die direkt über das Lieferwerk gemessen wird, oder am Erreichen des Spulendurchmessers. Ein im Bereich der Spulstation angeordneter Vollspulensensor 23 stellt den Spulautomaten ab, wenn sich keine leere Spule mehr auf dem Drehteller befindet.The automatic winder recognizes that the winding process is finished by means of the wound yarn length, which is measured directly by the delivery mechanism, or by reaching the bobbin diameter. A full-spool sensor 23 arranged in the area of the winding station stops the automatic winder when no empty spool is left on the turntable.

Sobald eine leere Spule an die Spulstation gelangt und die entsprechende Drehposition des Drehtellers 9 durch den Arretierstift 19 fixiert ist, wird die Spule S zwischen dem oberen Teil 3 und dem unteren Teil 4 der Halteeinrichtung festgeklemmt und fixiert und es beginnt der Spulvorgang durch Starten des Motors 2 und der Fadenverlegung 5.Once an empty bobbin reaches the winding station and the corresponding rotational position of the turntable 9 is fixed by the locking pin 19, the coil S between the upper part 3 and the lower part 4 of the holding device is clamped and fixed and it starts the winding process by starting the engine 2 and the thread laying 5.

Bei Abschluss des Spulvorgangs werden der Motor 2 und die Fadenverlegung 5 gestoppt, die betreffende Spule wird von der Halteeinrichtung 3, 4 freigegeben, der Arretierstift 19 wird gelöst und der Drehteller 9 wird um eine Teilung weiter gedreht. Die volle Spule kann jetzt abgenommen werden. Nach dem Stoppen des Motors 2 wird das Garn an einer fixen Position geklemmt und geschnitten und nach dem Anlaufen des Motors 2 so frei gegeben, dass der Anfang unter die erste Lage Garn zu liegen kommt.Upon completion of the winding operation, the motor 2 and the thread laying 5 are stopped, the coil in question is released from the holding device 3, 4, the locking pin 19 is released and the turntable 9 is further rotated by one pitch. The full spool can now be removed. After stopping the motor 2, the yarn is clamped at a fixed position and cut and released after starting the motor 2 so that the beginning comes to rest under the first layer of yarn.

Da auf Parallelspulautomaten in der Regel sehr feines Garn gespult wird, dauert die Herstellung einer Vollspule relativ lange (mindestens etwa 30 Minuten), sodass es bei dem dargestellten Spulenwechsler ausreicht, wenn eine Bedienungsperson etwa alle 90 Minuten an den Spulautomaten geht, die vollen Spulen abnimmt und leere Spulen nachfüllt.Since on spoolers usually very fine yarn is spooled, the production of a full bobbin takes relatively long (at least about 30 minutes), so that it is sufficient in the illustrated bobbin changer when an operator goes about every 90 minutes to the automatic winder, which decreases full bobbins and refills empty bobbins.
