Description

Die Erfindung bezieht sich auf ein Verfahren zum Spulenwechsel an einer mit einem Streckwerk, Flügeln, Spulen und einer Spulenbank versehenen Vorspinnmaschine, bei welchem bei laufender Vorspinnmaschine jeweils ein Luntenende einer von einer Streckwerkseinheit gelieferten Lunte an eine Leerhülse angelegt wird.The invention relates to a method for changing bobbins on one with a drafting system, wings, spools and a reel spool provided with with the roving machine running, one sliver end each Fuse supplied by a drafting unit to an empty tube is created.

Allgemeiner Stand der Technik ist, daß nach einem Spulenwechsel an einer Vorspinnmaschine, bei welchem die Preßfinger im allgemeinen ausgeschwenkt stehen, das aus der Führungsöse der Preßfingerpritsche heraushängende Luntenende an die neue, leere Hülse angelegt werden muß. Hierzu ist diese Hülse mit einem Lunten-Fangbereich, beispielsweise in Form eines sog. Klettbandes, versehen, welches das Luntenende faßt, wenn es an die Hülse angelegt wird. Um dies zu erreichen, muß die Vorspinnmaschine in Betrieb gesetzt werden, wobei sich die Preßfinger unter Wirkung der Zentrifugalkraft an die Hülsen anlegen.The general state of the art is that after a spool change on a roving machine in which the press fingers generally swung out that from the guide eye the ram end hanging out on the press finger platform the new, empty sleeve must be put on. This is this Sleeve with a fuse catch area, for example in the form a so-called Velcro tape, which is the end of the match grips when it is placed on the sleeve. To achieve this, the roving machine must be put into operation, the press fingers under the action of centrifugal force put on the sleeves.

An Vorspinnmaschinen mit Gesamtantrieb liefen hierbei alle Organe, also Streckwerk, Flügel, Spulen und Spulenbank zeitgleich an. Da das Anlegen der Preßfinger an die Hülsen und damit das Erfassen der Lunten erst bei einer Mindestdrehzahl erfolgt, blieben die Lunten bei den ersten Umdrehungen unerfaßt. Die vom Streckwerk gelieferte Lunte wurde nicht abgezogen und führte nachteiligerweise zu einem Durchhang der Lunten zwischen Streckwerk und Flügelkopf. Bisweilen wikkelte sich die Lunte auch um den Flügelkopf, was dann zu einem Luntenbruch führte, wenn die Vorspinnmaschine nicht rechtzeitig angehalten und die Hülse von Hand nachgedreht wurde. Auf jeden Fall mußte der Durchhang der Lunten anschließend durch den Abzugsüberschuß der Aufwindung zwischen Flügel und Spule gegenüber der Streckwerkslieferung abgebaut werden.Everyone was running on pre-roving machines with an overall drive Organs, i.e. drafting system, wings, spools and spool bank at the same time on. Since the pressing fingers on the sleeves and thus the fuses are only detected at a minimum speed the fuses remained undetected during the first revolutions. The fuse supplied by the drafting system was not removed and disadvantageously led to a sag of the Match between the drafting system and wing head. Sometimes it wobbled the fuse also around the wing head, which then a fuse break if the leader is not stopped in time and turned the sleeve by hand has been. In any case, the sag of the fuses had to follow by the deduction surplus of the wind between Wing and spool removed compared to delivery of drafting system become.

Ähnliche Probleme ergaben sich auch bei Vorspinnmaschinen mit getrennt steuerbaren Antrieben für die Flügel, die Spulen, das Streckwerk und die Spulenbank.Similar problems also arose with roving machines with separately controllable drives for the wings, the coils, the drafting system and the spool bank.

Solche Vorrichtungen werden in der FR-A-1 382 200 in der EP-A-0 455 254 offenbart. Die erstgenannte beschreibt 4 separate Antriebsmotoren für Streckwerk, Spulenbank, Spindeln und Flügel, wobei die Funktionen des mechanischen Schaltapparates in die elektronische Steuerung integriert wurden. Die Vorspinnmaschine nach EP-A-0 455 254 ist in unabhängige Sektionen unterteilt, deren gleichartige Aggregate von einem eigenen separat angesteuerten Antriebsmotor angetrieben werden. Bei Unterbrechung des Spinnvorganges an einzelnen Spinnstellen können die nicht davon betroffenen Sektionen weiter produzieren. Beide Schriften geben keine Hinweise zum Spulenwechsel.Such devices are disclosed in FR-A-1 382 200 in EP-A-0 455 254. The former describes 4 separate drive motors for drafting system, spool bank, Spindles and wings, the functions of the mechanical switching device in the electronic control were integrated. The roving machine according to EP-A-0 455 254 is divided into independent sections, the similar aggregates of their own separately controlled drive motor. When the The sections not affected can spin at individual spinning positions continue to produce. Both writings give no information about changing the bobbin.

Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren zum Spulenwechsel zu schaffen, bei welchen diesen technologischen Gegebenheiten Rechnung getragen und gewährleistet wird, daß das Luntenende funktionsgerecht erfaßt und unerwünschter Durchhang zwischen Streckwerk und Flügelkopf vermieden wird.In contrast, the present invention has the object based on a procedure for To create bobbin changes, in which this technological Conditions taken into account and guaranteed is that the match end is grasped functionally and undesirable Slack between drafting system and wing head avoided becomes.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zunächst nur die Flügel und die Spulen der Vorspinnmaschine angetrieben werden. Die Flügel und die Spulen werden entweder sofort vorwärts angetrieben oder sie werden zunächst rückwärts angetrieben, nach Ablauf einer bestimmten Zeitspanne dann stillgesetzt und anschließend vorwärts angetrieben, wobei die Stillsetzung der Flügel und der Spulen zeitgleich oder zeitlich versetzt erfolgen kann. This object is achieved in that initially only the wings and spools of the roving machine are driven. The wings and the coils are either immediately propelled forward or they will initially driven backwards after a certain period of time then stopped and then propelled forward, taking the shutdown of the wings and the coils can take place simultaneously or at different times.

Nach dem gestarteten Vorwärtsbetrieb der Flügel und der Spulen wird dann zeitverzögert das Streckwerk in Betrieb gesetzt.
Unter Vorwärtsantrieb wird hierbei der Antrieb der Flügel und der Spulen in normaler Drehrichtung verstanden, wohingegen unter Rückwärtsantrieb der Antrieb der Flügel und der Spulen entgegen normaler Drehrichtung verstanden wird.
After the forward operation of the wings and the bobbins has started, the drafting system is started with a time delay.
Forward drive is understood here to mean the drive of the wings and coils in the normal direction of rotation, whereas reverse drive means the drive of the wings and coils in the opposite direction of normal rotation.

Es ist also vorgesehen, daß zum Anlegen der Lunten an die Hülse nur die Flügel und die Spulen vorzugsweise mit gleicher Drehzahl in Betrieb gesetzt werden, wobei das Streckwerk in Ruhestellung verbleibt. Dabei erfolgt ein Anlegen der Preßfinger und der Lunten an die Hülsen, ohne daß sich ein Durchhang gelieferter und nicht erfaßter Lunten ergibt. Erst anschließend wird das Streckwerk in Betrieb gesetzt, und zwar mit einer verlangsamten Lieferung für beispielsweise eine Länge von etwa fünf Zentimetern, wodurch die Luntenenden durch den Luntenfangbereich, d.h. die Klettbänder, sicher erfaßt werden. Erst anschließend wird die normale Produktion der Vorspinnmaschine aufgenommen.It is therefore envisaged that to apply the fuses to the Sleeve only the wings and the coils preferably with the same Speed to be put into operation, the drafting system remains at rest. This creates an entry the press finger and the fuse on the sleeves without a sag of delivered and not recorded fuses results. Only then is the drafting system put into operation, with a slow delivery for example a length of about five centimeters, which makes the Match ends through the match catch area, i.e. the Velcro strips, be grasped safely. Only then is the normal production of the roving machine started.

Die Flügel und die Spulen können zum Anlegen des jeweiligen Luntenendes mit gleicher Drehzahl laufen, wobei zusätzlich die Möglichkeit besteht, daß das Streckwerk zunächst nur mit verlangsamter Lieferung in Betrieb gesetzt wird.The wings and the coils can be used to put on the respective Match ends run at the same speed, with additional there is the possibility that the drafting system initially only with slow delivery is put into operation.

In weiterer Ausgestaltung der Erfindung wird der Spulenbankantrieb nach erfolgtem Antrieb der Flügel und der Spulen oder nach erfolgtem Antrieb des Streckwerkes in Betrieb gesetzt. Die Bewegung der Spulenbank wird vorteilhafterweise jedoch spätestens dann aufgenommen, wenn die Lunten erfaßt sind.In a further embodiment of the invention, the coil bank drive after the wings and coils have been driven or put into operation after the drafting system has been driven. The movement of the spool bank is advantageously however at the latest when the fuses are grasped are.

Bei einer Vorrichtung mit getrennten und getrennt steuerbaren Antrieben der einzelnen Organe kann eine mit den Antrieben verbundene Steuereinheit zum gleichzeitigen Antreiben der Flügel und der Spulen bei zeitverzögertem Antreiben des Streckwerkes vorgesehen werden. Hierbei kann auch der Antrieb der Spulenbank mit der Steuereinheit verbunden sein.In a device with separate and separately controllable One can drive the individual organs with the drives connected control unit for simultaneous driving the wing and the coils with delayed driving of the drafting system can be provided. This can also the drive of the coil bank connected to the control unit his.

Bei einer Vorrichtung mit Gesamtantrieb kann eine mit einer Steuereinheit verbundene, dem Streckwerksantrieb zugeordnete Kupplung angeordnet sein. Weiterhin kann eine mit der Steuereinheit verbundene, dem Spulenbankantrieb angeordnete Kupplung eingesetzt werden.In the case of a device with an overall drive, one with a Control unit connected, assigned to the drafting system drive Be arranged clutch. Furthermore, one with the Control unit connected, the coil bank drive arranged Coupling can be used.

Here there is the possibility that the wings 3 and the coils 5 to put on of the respective match end with the same speed to run.

Nach gestartetem Vorwärtsbetrieb der Flügel 3 und der Spulen 5 wird dann zeitverzögert das Streckwerk 2 über den Antrieb 30 in Betrieb gesetzt, damit das aus der Pritsche des Preßfingers 15 heraushängende Luntenende der Lunten 7 bzw. 7' an der betreffenden Leerhülse 8 bzw. 8' mit Hilfe der Lunten-Fangvorrichtung 9, 9' haften kann. Dabei kann das Streckwerk 2 zunächst nur mit verlangsamter Lieferung in Betrieb gesetzt werden.After the forward operation of wings 3 and the coils has started 5, the drafting unit 2 is then delayed via the drive 30 put into operation so that out of the bed of the press finger 15 hanging match of the match 7 or 7 'match the relevant empty tube 8 or 8 'with the aid of the fuse catch device 9, 9 'can adhere. The drafting system can 2 initially only in operation with slow delivery be set.

Weiterhin besteht die Möglichkeit, daß die Bewegung der Spulenbank 6 spätestens dann aufgenommen wird, wenn die Lunten 7, 7' erfaßt sind.There is also the possibility that the movement of the coil bank 6 is recorded at the latest when the fuses 7, 7 'are detected.

Fig. 1 bezieht sich also auf eine Vorrichtung mit getrennt steuerbaren Antrieben 10, 20, 30 und 40 für die Flügel 3, die Spulen 5, das Streckwerk 2 und die Spulenbank 6. Es findet eine mit diesen Antrieben verbundene Steuereinheit 50 zum gleichzeitigen Antreiben der Flügel 3 und der Spulen 5 bei zeitverzögertem Antreiben des Streckwerkes 2 Anwendung. Hierbei besteht die Möglichkeit, daß auch der Antrieb 20 der Spulenbank 6 mit der Steuereinheit 50 verbunden ist.1 therefore relates to a device with separate controllable drives 10, 20, 30 and 40 for the wing 3, the spools 5, the drafting unit 2 and the spool bank 6.
