Description

Die Erfindung betrifft eine Kreuzspulen herstellende Textilmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a cheese making Textile machine according to the preamble of claim 1.

Solche Kreuzspulen herstellenden Textilmaschinen sind in verschiedenen Ausführungsformen bekannt.Such textile machines producing cross-wound bobbins are in known various embodiments.

Die DE 39 02 182 A1 beschreibt beispielsweise einen sogenannten Kreuzspulautomaten mit einer Vielzahl von Spulstellen, die jeweils einen separaten Spulstellenrechner aufweisen, der an eine zentrale Steuereinheit der Textilmaschine angeschlossen ist. Mit dieser zentralen Steuereinheit steht außerdem ein die Spulstellen versorgendes Serviceaggregat in Verbindung.DE 39 02 182 A1 describes, for example, a so-called Automatic winder with a large number of winding units each have a separate winding unit computer, the on a central control unit of the textile machine is connected is. With this central control unit there is also a Service unit supplying winding units in connection.

Das Serviceaggregat kann über die zentrale Steuereinheit und die Spulstellenrechner den Spulantrieb jeder Spulstelle so ansteuern, daß während des Wechselvorganges Kreuzspule/Leerhülse die Fadenführungstrommel mit einer gegenüber dem "normalen" Spulprozeß geänderten Umfangsgeschwindigkeit rotiert.The service unit can via the central control unit and the winding unit computer the winding drive of each winding unit like this control that during the change process Cheese / empty tube the thread guide drum with a changed compared to the "normal" winding process Peripheral speed rotates.

Durch die DE 42 21 504 A1 ist weiter ein Kreuzspulautomat bekannt, dessen Arbeitsstellen über eine Busleitung mit einem Servicefahrzeug verbunden sind.
Wenn an einer der Arbeitsstellen ein Bedienbedarf auftritt, setzt die betreffende Arbeitsstelle ein optisches Signal, das von dem vor den Arbeitsstellen patrouillierenden Servicefahrzeug erkannt und nach dessen Positionierung an dieser Arbeitsstelle durch ein Lichtsignal an die Arbeitsstelle bestätigt wird. Durch dieses Lichtsignal wird die betreffende Arbeitsstelle aktiviert, so daß anschließend vom Servicefahrzeug aus über die Busleitung Arbeitsbefehle, beispielweise Antriebswalze rückwärtsdrehen, Arbeitsstelle abblasen oder dergleichen an die betreffende Arbeitsstelle gegeben werden können.
From DE 42 21 504 A1, a cross winder is also known, the workstations of which are connected to a service vehicle via a bus line.
If there is a need for operation at one of the workplaces, the workstation in question sets an optical signal which is recognized by the service vehicle patrolling in front of the workplaces and which is confirmed at the workstation by a light signal to the workstation. This light signal activates the relevant work station, so that work commands, for example turning the drive roller backwards, blowing off work stations or the like, can then be given to the relevant work station from the service vehicle via the bus line.

Serviceaggregate, die bei Bedarf die an den Spulstellen solcher Kreuzspulautomaten fertiggestellten Kreuzspulen gegen Leerhülsen wechseln, sind ebenfalls bekannt und beispielsweise in der nachveröffentlichten DE 195 20 132 A1 beschrieben. Derartige Serviceaggregate, sogenannte Kreuzspulenwechsler, verfügen über zahlreiche Handhabungseinrichtungen, die es ihnen ermöglichen, eine Kreuzspule aus dem Spulenrahmen der betreffenden Spulstelle zu nehmen und durch eine Leerhülse zu ersetzen. An der Leerhülse bzw. zwischen der Leerhülse und einem rotierbaren Bauteil des Spulenrahmens wird anschließend ein Fadenende festgelegt, das von einem in einer Abspulstellung positionierten Spinnkops stammt.Service units, if necessary, those at the winding units Automatic winding machines finished cheese against Changing empty tubes are also known and for example described in the post-published DE 195 20 132 A1. Such service units, so-called cross-coil changers, have numerous handling facilities that give them allow a cheese from the bobbin frame of the to take the relevant winding unit and through an empty tube replace. On the empty tube or between the empty tube and a rotatable component of the coil frame is then a thread end set by one in an unwind position positioned spinning cops.

Diese bekannten Kreuzspulenwechsler haben sich in der Praxis bewährt. Allerdings können Schwierigkeiten auftreten, wenn auf den Kreuzspulautomaten konische Hülsen bewickelt werden, die aus Pappe oder einem ähnlich wenig standfesten Material gefertigt sind.
Das heißt, bei solchen Hülsen kann es gelegentlich vorkommen, daß die Hülsen im Bereich ihres großen Durchmessers aufgeweitet werden und sich dann an der Hülsenaufnahme des Spulenrahmens verklemmen. In einem solchen Fall ist dann oft kein automatischer Wechsel mehr möglich, es muß manuell eingegriffen werden.
These known cross-wound bobbin changers have proven themselves in practice. However, difficulties can arise if conical sleeves are wound on the automatic winder, which are made of cardboard or a similarly less stable material.
This means that with such sleeves it can occasionally happen that the sleeves are expanded in the region of their large diameter and then jam on the sleeve holder of the coil frame. In such a case, automatic change is often no longer possible, and manual intervention is required.

Auch beim Festlegen des Fadenendes zwischen der Stirnseite einer Leerhülse und der Hülsenaufnahme am Spulenrahmen kann es zu Schwierigkeiten kommen, insbesonders wenn die verwendete, relativ empfindliche Papphülse nicht mehr ganz in Ordnung ist, das heißt, wenn die Hülse beispielsweise im Bereich ihres großen Durchmessers, wo üblicherweise die Fußreservewicklung angeordnet wird, etwas eingedrückt ist. Even when setting the thread end between the front An empty tube and the tube holder on the coil frame can difficulties, especially if the one used relatively sensitive cardboard tube is no longer in order, that is, if the sleeve, for example, in the area of their large diameter, where usually the foot reserve winding is arranged, something is indented.

Ausgehend vom vorgenannten Stand der Technik, liegt der Erfindung die Aufgabe zugrunde, den durch selbsttätig arbeitende Kreuzspulenwechsler ausgeführten Wechselvorgang Kreuzspule/Leerhülse, insbesonders beim Einsatz empfindlicher konischer Hülsen, sicherer zu machen.Based on the aforementioned prior art, the Invention based on the task by automatically working cross-wound bobbin changer Cross-wound bobbin / empty tube, especially when using sensitive conical sleeves to make more secure.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, die die im Anspruch 1 beschriebenen Merkmale aufweist.This object is achieved by a device solved, which has the features described in claim 1.

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

Die erfindungsgemäße Ausführungsform hat dabei den Vorteil, daß auch dann, wenn es zum Beispiel aufgrund einer fehlerhaften Hülse zu einer Verklemmung der Hülse der Kreuzspule an der Hülsenaufnahme des Spulenrahmens gekommen ist, kein manueller Eingriff seitens des Bedienpersonals notwendig wird.
Wenn sich beispielsweise eine konische Kreuzspule mit einer im Bereich ihres großen Durchmessers aufgeweiteten Papphülse an der Hülsenaufnahme eines Spulenrahmens festgesetzt hat, was vom Serviceaggregat durch einen entsprechenden Sensor detektiert wird, initiiert das Serviceaggregat, dessen Steuerungsrechner über den Maschinenbus direkt auch mit dem Arbeitsstellenrechner der zur Zeit bedienten Spulstelle verbunden ist, den betreffenden Arbeitsstellenrechner derart, daß dieser das Betätigungsventil für die Spulenbremse definiert, vorzugsweise mehrfach kurz, ansteuert. Durch die damit verbundene ruckartige Bewegung der Hülsenaufnahme wird in der Regel die Kreuzspule vom Spulenrahmen gelöst.
The embodiment according to the invention has the advantage that even if, for example, the sleeve of the cross-wound bobbin is jammed on the sleeve receptacle of the bobbin frame due to a defective sleeve, no manual intervention by the operating personnel is necessary.
If, for example, a conical cheese with a cardboard tube widened in the area of its large diameter has stuck to the tube holder of a coil frame, which is detected by the service unit by means of a corresponding sensor, the service unit initiates its control computer via the machine bus directly with the workstation computer of the time operated winding station is connected, the relevant workstation computer so that it defines the actuating valve for the coil brake, preferably several times briefly. The associated jerky movement of the tube holder usually releases the cheese from the bobbin frame.

Entsprechend kann der Steuerungsrechner des Serviceaggregates über den Maschinenbus den Arbeitsstellenrechner der Spulstelle auch beim Festlegen des Fadenendes an der Leerhülse initiieren. Durch definiertes Beaufschlagen der Spulenbremse kann in diesem Fall sichergestellt werden, daß der zwischen der Stirnseite der Spulenhülse und der Hülsenaufnahme des Spulenrahmens gespannt gehaltene Faden an beiden gegenüberliegenden Anlageflächen der Stirnseite der Hülse geklemmt wird.The control computer of the service unit can accordingly the workstation computer of the winding unit via the machine bus also initiate when setting the thread end on the empty tube. By defined application of the coil brake in this Case be ensured that the between the front of the Coil sleeve and the sleeve holder of the coil frame stretched held thread on both opposite contact surfaces of the Face of the sleeve is clamped.

In bevorzugter Ausführungsform wird das Lösen einer Kreuzspulenhülse von der Hülsenaufnahme des Spulenrahmens, wie im Anspruch 2 dargelegt, durch die Spulenrahmenabhebeeinrichtung unterstützt, die, wie die Spulenbremse, über den Maschinenbus vom Steuerungsrechner des Serviceaggregates definiert ansteuerbar ist.
Durch entsprechendes Ansteuern eines in die Druckversorgungsleitung eingeschalteten Ventiles kann der Spulenrahmen ruckartig bewegt und damit das Lösen der Kreuzspule aus dem Spulenrahmen wirkungsvoll unterstützt werden.
In a preferred embodiment, the release of a cross-wound bobbin from the bobbin holder of the bobbin frame, as set out in claim 2, is supported by the bobbin frame lifting device which, like the bobbin brake, can be controlled in a defined manner by the control computer of the service unit via the machine bus.
By appropriately controlling a valve switched into the pressure supply line, the bobbin frame can be moved jerkily and thus the release of the cross-wound bobbin from the bobbin frame can be effectively supported.

In vorteilhafter Ausgestaltung erfolgt dabei eine impulsartige Betätigung der Spulenbremse und/oder der Spulenrahmenabhebeeinrichtung. Durch das impulsartige Ansteuern der Spulenbremse kommt es zwischen der Hülsenaufnahme des zu diesem Zeitpunkt geöffneten Spulenrahmens und der Kreuzspule zu kurzen Relativbewegungen, die dazu führt, daß sich auch festsitzende Kreuzspulenhülsen sicher von den betreffenden Hülsenaufnahmen lösen.In an advantageous embodiment, a pulse-like takes place Actuation of the coil brake and / or the Coil frame lifting device. Through the impulsive control the coil brake occurs between the sleeve holder of the open the bobbin frame and the cheese short relative movements that leads to that too tightly wound bobbin tubes securely from the concerned Loosen sleeve receptacles.

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.

Wie insbesondere aus Fig. 2 ersichtlich, ist das Serviceaggregat 23 mit Fahrwerken 24, 25 auf maschinenlangen Laufbahnen 26, 27, die oberhalb der Spulstellen 2 angeordnet sind, verfahrbar gelagert. Das Serviceaggregat 23 sorgt dabei nicht nur dafür, daß die auf der Spulstelle fertiggestellte Kreuzspule 11 auf die Kreuzspulentransporteinrichtung 21 ausgerollt wird, sondern es wechselt auch jeweils selbsttätig eine Leerhülse 28 in den Spulenrahmen der betreffenden Spulstelle 2 ein.
Die entsprechende Leerhülse 28 entnimmt das Serviceaggregat 23 dabei vorzugsweise einem spulstelleneigenen Leerhülsenmagazin 22.
As can be seen in particular from FIG. 2, the service unit 23 is movably mounted with carriages 24, 25 on machine-long tracks 26, 27, which are arranged above the winding units 2. The service unit 23 not only ensures that the bobbin 11 finished on the bobbin is rolled out onto the bobbin transport device 21, but it also automatically changes an empty tube 28 into the bobbin frame of the bobbin 2 in question.
The corresponding empty tube 28 is preferably taken from the service unit 23 from an empty tube magazine 22 which is provided in the winding unit.

Wie vorstehend bereits angedeutet, verfügen derartige Textilmaschinen über ein Spulen- und Hülsentransportsystem 3. In Fig. 2 ist von diesem umfangreichen Transportsystem 3 lediglich die maschinenlange Transportstrecke 4, die hinter den Spulstellen 2 verlaufende, reversierende Kopszuführstrecke 5, eine der zu den Spulstellen 2 führenden Quertransportstrecken 6 sowie die Rückführstrecke 7 dargestellt.
Die angelieferten Spinnkopse 9 werden in den Abspulstellungen 10, die sich im Bereich der Quertransportstecken 6 an den Spulstellen 2 befinden, zu großvolumigen Kreuzspulen 11 umgespult. Die einzelnen Spulstellen 2 verfügen dabei, wie bekannt und daher nur angedeutet, über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb dieser Arbeitsstellen gewährleisten.
In Fig. 2 ist mit 30 der vom Spinnkops 9 zur Kreuzspule 11 laufende Faden, mit 12 eine Saugdüse, mit 42 ein Greiferrohr, mit 13 eine Spleißeinrichtung, mit 14 eine Fadenspanneinrichtung, mit 15 ein Fadenreiniger mit Fadenschneideinrichtung sowie mit 16 eine Paraffiniereinrichtung angedeutet.
As already indicated above, textile machines of this type have a bobbin and tube transport system 3. In FIG. 2, of this extensive transport system 3, only the machine-long transport path 4, the reversing bobbin feed path 5 running behind the winding units 2, is one of the leading to the winding units 2 Cross transport routes 6 and the return route 7 are shown.
The delivered spinning bobbins 9 are rewound into large-volume cross-wound bobbins 11 in the unwinding positions 10, which are located in the region of the transverse transport slots 6 at the winding stations 2. The individual winding units 2 have, as is known and therefore only hinted at, various devices which ensure proper operation of these work stations.
2, the thread running from the spinning cop 9 to the package 11 is indicated by 30, by 12 a suction nozzle, by 42 a gripper tube, by 13 a splicing device, by 14 a thread tensioning device, by 15 a thread cleaner with thread cutting device and by 16 a waxing device.

Die Spulenantriebstrommel, die die Kreuzspule 11 während des Spulvorganges über Reibschluß 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 die Schwenkachse 19 begrenzt drehbar, ein Schwenkblech 20 angeordnet, über das die fertigen Kreuzspulen auf die hinter den Spulstellen 2 verlaufende Kreuzspulentransporteinrichtung 21 überführbar sind.The bobbin drive drum, which the cheese 11 during the Drives winding process over friction, carries the Reference number 17. During the winding process, the cheese is 11 held in a coil frame 18 which is about an axis 19 is pivotally mounted. Below the coil frame 18 is also rotatable to a limited extent about the pivot axis 19 Swivel plate 20 arranged over which the finished cheese to the one behind the winding units 2 Cross-wound bobbin transport device 21 can be transferred.

Die Spulstellen 2 werden über ein Serviceaggregat, einen sogenannten Kreuzspulenwechsler 23, versorgt. Das heißt, der Kreuzspulenwechsler 23 sorgt dafür, daß Kreuzspulen 11, die einen vorbestimmten Durchmesser erreicht haben, auf die Kreuzspulentransporteinrichtung 21 ausgetragen werden und daß anschließend aus dem Leerhülsenmagazin 22 jeweils eine Leerhülse 28 in den Spulenrahmen 18 eingewechselt wird.The winding units 2 are a service unit, one so-called cross-coil changer 23 supplied. That is, the Cross-coil changer 23 ensures that cross-wound bobbins 11, the have reached a predetermined diameter on the Cross-coil transport device 21 are carried out and that then one each from the empty sleeve magazine 22 Empty sleeve 28 is replaced in the coil frame 18.

In Fig. 2 sind einige der im Zuge des Wechselvorganges Kreuzspule/Leerhülse benötigten Handhabungselemente des Serviceaggregates 23 dargestellt, die da sind: Rahmenöffner 29, Rahmenheber 32, Spulenführungsvorrichtung 33 sowie Hülsenzubringer 31.2 are some of those in the course of the change process Package / empty tube required handling elements of the Service units 23 shown, which are: frame opener 29, Frame lifter 32, coil guide device 33 and Sleeve feeder 31.

Der Übersichtlichkeit halber wurde in dieser Figur auf die Darstellung weiterer Handhabungselemente derartiger Kreuzspulenwechsler verzichtet. Die Vorrichtung zum Erstellen einer Kopfreservewicklung ist beispielsweise nicht gezeigt.For the sake of clarity, this figure refers to the Representation of further handling elements of such Cross coil changer dispensed with. The device for creating a head reserve winding is not shown, for example.

Die Vorrichtung zum Anlegen des Fadens 30 an die Leerhülse 28 beziehungsweise zum Spannen des Fadens 30 zwischen der Stirnseite der Leerhülse 28 und der Hülsenaufnahme 53 des Spulenrahmens 18 ist in Fig. 4 lediglich schematisch angedeutet und trägt die Bezugszahl 59. The device for applying the thread 30 to the empty tube 28 or for tensioning the thread 30 between the Front side of the empty sleeve 28 and the sleeve receptacle 53 of the The coil frame 18 is only indicated schematically in FIG. 4 and bears the reference number 59.

Wie in den Figuren 1 bis 3 dargestellt, sind über den Maschinenbus 40 die Zentralsteuereinheit 37 der Textilmaschine 1, die Arbeitsstellenrechner 39 der einzelnen Spulstellen 2 und der Steuerungsrechner 38 des Serviceaggregates 23 miteinander verbunden.As shown in Figures 1 to 3, are about the Machine bus 40 the central control unit 37 of the Textile machine 1, the job computer 39 of each Winding units 2 and the control computer 38 of the Service units 23 connected to each other.

Die Fig. 3 zeigt außerdem, daß eine in den Spulenrahmen 18 integrierte Spulenbremse 50 sowie eine Spulenrahmenabhebeeinrichtung 49 über Versorgungsleitungen 51, 52; in die Ventilelemente 43, 44 eingeschaltet sind sowie eine Versorgungsleitung 48, mit einer Druckluftquelle 45 in Verbindung stehen.3 also shows that one in the coil frame 18th integrated coil brake 50 and one Coil frame lifting device 49 over Supply lines 51, 52; into the valve elements 43, 44 are switched on and a supply line 48, with a Compressed air source 45 are connected.

Die Ventilelemente 43, 44 sind dabei über Steuerleitungen 46, 47 an den Arbeitsstellenrechner 39 der jeweiligen Spulstelle 2 angeschlossen. Das bedeutet, sowohl die Spulenbremse 50 als auch die Spulenrahmenabhebeeinrichtung 49 ist durch den jeweiligen Arbeitsstellenrechner 39 definiert ansteuerbar.The valve elements 43, 44 are over Control lines 46, 47 to the job computer 39 of the respective winding unit 2 connected. That means both the Coil brake 50 and the coil frame lifting device 49 is defined by the respective job computer 39 controllable.

Bei der in Fig. 4 näher dargestellten Spulenbremse 50 handelt es sich um eine, an sich bekannte, pneumatisch betätigbare Einrichtung.
Die Spulenbremse 50 wird dabei über die Versorgungsleitung 51 mit einem Druckmedium, beispielsweise Luft mit einem Druck von 3,5 bar, beaufschlagt. Das in den Zylinderraum 62 einströmende Druckmedium wirkt dabei gegen den hülsenartig ausgebildeten Kolben 55 und schiebt diesen gegen die Kraft eines Federelementes 57 in Richtung der Hülsenaufnahme 53.
Eine an der Hülsenaufnahme 53 anliegende, zwischen den Armen des Spulenrahmens 18 gehaltene Hülse einer Kreuzspule 11 bzw., wie in Figur 4 dargestellt, eine Leerhülse 28 bilden dabei ein Widerlager. Das bedeutet, bei Druckbeaufschlagung der Spulenbremse 50 drückt ein mit dem Kolben 55 verbundener Bremsansatz 63 gegen eine axial bewegliche jedoch drehfest angeordnete Bremsscheibe 56, die ihrerseits gegen eine rotierbar gelagerte Bremsfläche 64 der Hülsenaufnahme 53 gedrückt wird. Die an der Bremsfläche 64 anliegende Bremsscheibe 56 verhindert dabei die weitere Rotation der Hülsenaufnahme 53 und damit der Kreuzspule 11.
The coil brake 50 shown in more detail in FIG. 4 is a pneumatically actuated device which is known per se.
The coil brake 50 is acted upon via the supply line 51 with a pressure medium, for example air with a pressure of 3.5 bar. The pressure medium flowing into the cylinder chamber 62 acts against the sleeve-like piston 55 and pushes it against the force of a spring element 57 in the direction of the sleeve holder 53.
A sleeve of a cross-wound bobbin 11 lying against the sleeve receptacle 53 and held between the arms of the bobbin frame 18 or, as shown in FIG. 4, an empty sleeve 28 form an abutment. This means that when the coil brake 50 is pressurized, a brake shoulder 63 connected to the piston 55 presses against an axially movable but non-rotatably arranged brake disk 56, which in turn is pressed against a rotatably mounted brake surface 64 of the sleeve receptacle 53. The brake disk 56 resting on the braking surface 64 prevents further rotation of the sleeve receptacle 53 and thus the cheese 11.

Wie anhand der Figur 4 nachvollziehbar, führt eine impulsartige Betätigung der Spulenbremse 50, insbesondere bei geöffnetem Spulenrahmen 18, zu einer kurzen axialen Bewegung der Hülsenaufnahme 53. Da eine relativ schwere Kreuzspule, die beispielsweise mit ihrer aufgeweiteten konischen Papphülse an der Hülsenaufnahme 53 festliegt, dieser ruckartigen Bewegung der Hülsenaufnahme nicht oder nur unvollkommen folgen kann, stellt sich der positive Effekt ein, daß sich die Kreuzspule 11 ohne manuellen Eingriff von Hülsenaufnahme 53 löst.As can be seen from FIG. 4, an impulse-like leads Actuation of the coil brake 50, in particular when the brake is open Coil frame 18, for a short axial movement of the Sleeve receptacle 53. Since a relatively heavy cheese, the for example with its flared conical cardboard sleeve the sleeve receptacle 53 is fixed, this jerky movement cannot or only imperfectly follow the sleeve receptacle, the positive effect arises that the cheese 11 without manual intervention from the sleeve receptacle 53.

Funktion der Einrichtung:
Wenn an einer der Spulstellen 2 des Kreuzspulautomaten 1 eine Kreuzspule 11 ihren vorgegebenen Durchmesser oder ihre vorgegebene Fadenlänge erreicht hat, wird über die Fadenschneideinrichtung 16 zunächst der Faden 30 getrennt, die Kreuzspule durch die Spulenrahmenabhebeeinrichtung 49 von der Spulenantriebstrommel 17 abgehoben und die Kreuzspule 11 sowie die Antriebstrommel 17 in den Stillstand abgebremst.
Das Abbremsen der Kreuzspule 11 erfolgt dabei mittels der Spulenbremse 50, deren Betätigungsventil 43 vom zugehörigen Arbeitsstellenrechner 39 entsprechend angesteuert wird.
Function of the facility:
When at one of the winding stations 2 of the automatic winder 1 a package 11 has reached its predetermined diameter or its predetermined thread length, the thread 30 is first separated via the thread cutting device 16, the package is lifted by the bobbin frame lifting device 49 from the bobbin drive drum 17 and the package 11 and the Drive drum 17 braked to a standstill.
The cross-wound bobbin 11 is braked by means of the bobbin brake 50, the actuating valve 43 of which is controlled accordingly by the associated workstation computer 39.

Da das Serviceaggregat 23 nur einen laufenden Faden 30 fassen kann, wird die Kreuzspule 11 anschließend wieder auf die Antriebstrommel 17 abgesenkt und der Faden 30 in der Spleißeinrichtung 13 der Spulstelle 2 neu verspleißt.Since the service unit 23 can only take one running thread 30 can, the cheese 11 is then back on the Drive drum 17 lowered and the thread 30 in the Splicing device 13 of the winding unit 2 newly spliced.

Der Arbeitsstellenrechner 39 der betreffenden Spulstelle 2 hat inzwischen über den Maschinenbus 40 das Serviceaggregat 23 verständigt, das sich umgehend an der betreffenden Spulstelle 2 positioniert.The workstation computer 39 of the winding unit 2 in question has in the meantime, via the machine bus 40, the service unit 23 informed that immediately at the winding unit concerned 2 positioned.

Das Serviceaggregat 23 nimmt mit einem (nicht darstellten) Fadenheber zunächst den sich zwischen dem in Abspulposition 10 stehenden Spinnkops 9 und der Kreuzspule 11 erstreckenden Faden 30 auf, um ihn für den nachfolgenden Wechsel- und Wiederanspulvorgang bereitzuhalten.
Je nach gewünschter Ausbildung der Kreuzspule 11 wird der Faden 30 später, zum Beispiel nach dem Erstellen einer Topcone-Wicklung, durch das Serviceaggregat 23 erneut gekappt, wobei das Serviceaggregat den vom Spinnkops 9 kommenden Unterfaden festhält.
With a thread lifter (not shown), the service unit 23 first picks up the thread 30 extending between the spinning cop 9 in the unwinding position 10 and the package 11 in order to keep it ready for the subsequent changing and rewinding process.
Depending on the desired configuration of the package bobbin 11, the thread 30 is later cut again, for example after the creation of a top cone winding, by the service unit 23, the service unit holding the bobbin thread coming from the spinning cop 9.

Im Zuge des Wechselvorganges wird die Kreuzspule 11 nach dem Anbringen der geforderten Topcone-Wicklung durch die vorstehend beschriebenen Handhabungseinrichtungen auf die Kreuzspulentransporteinrichtung 21 übergeben. das heißt, mittels des Rahmenöffners 29 wird zunächst der Öffnungshebel 60 des Spulenrahmens 18 nach außen gedrückt, so daß die Kreuzspule 11 auf ein unterhalb der Spule angeordnetes Schwenkblech 20 gelangt. Dieses um die Schwenkachse 19 begrenzt drehbar gelagerte Schwenkblech 20 wird dann durch den Rahmenheber 32 angehoben, so daß die Kreuzspule 11, durch die Spulenführungseinrichtung 33 geführt, auf die Kreuzspulentransporteinrichtung 21 rollt.In the course of the change process, the cheese 11 is after Attach the required Topcone winding by the above described handling devices on the Pass the bobbin winding device 21. this means, The opening lever 60 is first opened by means of the frame opener 29 of the coil frame 18 pressed outward so that the Cross-wound bobbin 11 on one arranged below the bobbin Swivel plate 20 arrives. This is limited around the pivot axis 19 rotatably mounted swivel plate 20 is then by the Frame lifter 32 raised so that the cheese 11 through which Guided coil guide 33 on the Cross-wound bobbin transport device 21 rolls.

Die ordnungsgemäße Ankunft der Kreuzspule 11 auf der Kreuzspulentransporteinrichtung 21 wird dabei, zum Beispiel durch einen am Serviceaggregat 23 angeordneten, an den Steuerungsrechner 38 angeschlossenen Ultraschallsensor 61, überwacht. Das heißt, der Steuerungsrechner 38 des Serviceaggregates 23 wird durch ein entsprechendes Signal des Sensors 61 darüber informiert, ob die Kreuzspule 11 ihre vorschriftsmäßige Position auf der Kreuzspulentransporteinrichtung 21 erreicht hat.. The proper arrival of the cheese 11 on the Cross-wound bobbin transport device 21 is used, for example by a arranged on the service unit 23 to the Control computer 38 connected ultrasonic sensor 61, supervised. That is, the control computer 38 of the Service unit 23 is by a corresponding signal of the Sensor 61 informed whether the package 11 their correct position on the Cheese has reached 21 ..

Wenn der Sensor 61 festgestellt hat, daß die Kreuzspule 11 ihre reguläre Position nicht erreicht hat, bedeutet das oft, vorallem wenn am Kreuzspulautomat konisch Hülsen aus einem relativ empfindlichen Material bespult werden, daß die Kreuzspule mit ihrer Hülse 28 noch in der Hülsenaufnahme 53 des Spulenrahmens 18 festgeklemmt ist.If the sensor 61 has detected that the cheese 11 their has not reached regular position, it often means especially when conical cores from a relatively sensitive material that the Cross-wound bobbin with its sleeve 28 still in the sleeve receptacle 53 of the Coil frame 18 is clamped.

Der Steuerungsrechner 38 des Bedienaggregates 23 initiiert aufgrund des entsprechenden Signales des Ultraschallsensors 61 über den Maschinenbus 40 den Arbeitsstellenrechner 39 der betreffenden Spulstelle 2, der daraufhin seinerseits die Ventileinrichtungen 43 und/oder 44 ansteuert, so daß die Spulenbremse 50 und/oder die Spulenrahmenabhebeeinrichtung 49 aktiviert werden.The control computer 38 of the operating unit 23 initiates based on the corresponding signal from the ultrasonic sensor 61 via the machine bus 40 to the workstation computer 39 relevant winding unit 2, which in turn the Valve devices 43 and / or 44 controls so that the Coil brake 50 and / or the coil frame lifting device 49 to be activated.

Vorzugsweise steuert der Arbeitsstellenrechner 39 dabei die Ventileinrichtungen 43, 44 derart an, daß die Spulenbremse 50 und/oder die Spulenabhebeeinrichtung 49 impulsartig beaufschlagt wird/werden. Durch diese impulsartige Betätigung der Spulenbremse 50 beziehungsweise der Spulenabhebeeinrichtung 49 löst sich in der Regel die Kreuzspule 11 vom Spulenrahmen und gleitet auf das Schwenkblech 20. Die Kreuzspule 11 kann dann, wie vorstehend bereits beschrieben, ohne daß ein manueller Eingriff notwendig ist, an die Kreuzspulentransporteinrichtung 21 überführt werden.The workstation computer 39 preferably controls the Valve devices 43, 44 in such a way that the coil brake 50 and / or the coil lifting device 49 in a pulsed manner will be acted upon. Through this impulsive actuation the coil brake 50 and the Coil lifting device 49 usually releases Cross bobbin 11 from the bobbin frame and slides on it Swing plate 20. The cheese 11 can then, as above already described without manual intervention is transferred to the cross-wound bobbin transport device 21 become.
