Description

Die Erfindung betrifft eine Vorrichtung zur Inbetriebnahme einer Arbeitsstelle einer Kreuzspulen herstellenden Textilmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for starting up a Work station of a textile machine producing cross-wound bobbins according to the preamble of claim 1.

Beim Betrieb von Kreuzspulen herstellenden Textilmaschinen, insbesondere Kreuzspulautomaten, ist es üblich und beispielsweise in der DE 40 05 752 A1 beschrieben, im Falle eines Fadenbruches oder bei einem Ablaufspulenwechsel über den Spulstellenrechner der betreffenden Spulstelle zunächst eine arbeitstelleneigene Fadenverbindungsautomatik zu aktivieren.
Das heißt, zunächst wird eine Saugdüse an die Oberfläche der langsam gegen die Wickelrichtung drehenden Auflaufspule angelegt. Nach dem Erfassen des Oberfadenendes schwenkt die Saugdüse in ihre Ausgangslage, in der die Saugdüsenöffnung unterhalb einer Spleißvorrichtung positioniert ist, zurück. Der sich zwischen der Auflaufspule und der Saugdüse erstreckende Fadenstrang wird dabei in einen oberhalb der Fadenverbindungsvorrichtung angeordneten elektronischen Reiniger, eine in diesem Bereich positionierte Klemm- und Schneideinrichtung sowie, durch entsprechende Leitkonturen von Fadenleitblechen und Fadenleitbügeln geführt, in die Scherenhälfte einer unterhalb der Spleißvorrichtung befindlichen Schneideinrichtung eingezogen.
When operating cross-wound textile machines, in particular cross-winding machines, it is customary and described, for example, in DE 40 05 752 A1, in the event of a thread break or when changing the bobbin, to first activate an automatic thread connection automatic on the winding station computer of the winding station in question.
That is, first a suction nozzle is placed on the surface of the package which rotates slowly against the winding direction. After the upper thread end has been gripped, the suction nozzle swings back into its starting position, in which the suction nozzle opening is positioned below a splicing device. The thread strand extending between the take-up spool and the suction nozzle is fed into an electronic cleaner arranged above the thread connecting device, a clamping and cutting device positioned in this area and, through corresponding guide contours of thread guide plates and thread guide bars, into the scissor half of a cutting device located below the splicing device moved in.

Nahezu gleichzeitig mit der Saugdüse schwenkt ein in einer unteren Ausgangslage positioniertes Greiferrohr in eine obere Arbeitsstellung und bringt dabei einen bis dahin in einem Fadenspanner gehaltenen, von der Ablaufspule abgezogenen Unterfaden mit. Beim Einschwenken des Greiferrohres in seine obere Arbeitsstellung gleitet der Unterfaden, der ebenfalls an entsprechenden Fadenleitkonturen geführt ist, in eine geöffnete Fadenklemme sowie eine geöffnete Schneideinrichtung.Almost simultaneously with the suction nozzle swings in one lower starting position positioned gripper tube in an upper Working position and brings you in one Thread tensioner held, pulled off the payout spool Bobbin thread with. When swiveling the gripper tube into his The upper thread slides on the lower thread, which is also on corresponding thread guide contours is guided into an open Thread clamp and an open cutting device.

Der Unter- und der Oberfaden werden anschließend auf die richtige Länge abgeschnitten, in sogenannten Auflöseröhrchen vorbereitet und in der Spleißeinrichtung miteinander verbunden.The lower and the upper thread are then on the right one Cut off length, prepared in so-called dissolution tubes and connected to each other in the splicer.

Das bedeutet, an den Arbeitsstellen eines Kreuzspulautomaten werden, um, zum Beispiel nach einem Fadenbruch, den Betrieb automatisch fortführen zu können, stets sowohl ein von der Kreuzspule zurückgeholter Oberfaden als auch ein vom Ablaufkops kommender Unterfaden benötigt.That means at the workplaces of an automatic winder to, for example, after a thread break, the operation to be able to continue automatically, always one of the Bobbin retrieved upper thread as well as one from the drain cop coming bobbin needed.

Bei einem Kreuzspulen-/Leerhülsenwechsel muß entsprechend sichergestellt sein, daß der Unterfaden bis in den Bereich der im Spulenrahmen der betreffenden Arbeitsstelle gehalterten Leerhülse reicht und somit an dieser festgelegt werden kann.When changing the bobbin / empty tube, it must be changed accordingly be sure that the bobbin thread in the range of Coil frame of the job in question enough and can therefore be fixed on this.

Von Spulmaschinen, die über einen selbsttätig arbeitenden Bedienläufer, allgemein als Kreuzspulenwechsler bezeichnet, verfügen, ist es bekannt (DE 195 33 833 A1), daß im Falle eines Kreuzspulen-/Leerhülsenwechsels der noch zwischen dem Vorlagekops und der fertiggestellten Kreuzspule gespannte Faden zunächst durch ein spezielles Handhabungsmittel des Bedienläufers, einen sogenannten Fadenheber, aufgenommen und durch am Fadenheber angeordnete Schneid- und Klemmelemente definiert abgetrennt wird. Dabei wird das mit dem Vorlagekops verbundene Fadenende festgehalten und anschließend an eine im Spulenrahmen positionierte Leerhülse angelegt. From winding machines that work independently Operator runner, commonly referred to as a package changer, have, it is known (DE 195 33 833 A1) that in the case of a Cross bobbin / empty tube change of still between the original cop and the finished bobbin tensioned thread initially through a special handling device of the operator runner, a so-called thread lifter, picked up and by the thread lifter arranged cutting and clamping elements is separated defined. The end of the thread connected to the master bobbin held and then to one in the coil frame positioned empty tube created.

Des weiteren ist es zum Beispiel durch die DE 24 63 461 C2 bekannt, im Bereich der Spulenrahmen der einzelnen Arbeitsstellen jeweils eine separate, das heißt, spulstelleneigene Klemm- und Schneideinrichtung zu installieren, die im Falle eines Kreuzspulen-/Leerhülsenwechsels den Faden vor dem Ausstoßen der Kreuzspule festgelegt, so daß der Faden anschließend zum Anlegen an eine Hülse bereitliegt.Furthermore, it is, for example, from DE 24 63 461 C2 known, in the area of the coil frames of the individual jobs each a separate, that is, winding station own clamping and Install cutting device, which in the case of a Cross bobbin / empty tube change the thread before ejecting the Fixed the bobbin so that the thread can then be put on on a sleeve.

Die vorbeschriebenen Einrichtungen weisen allerdings den Nachteil auf, daß sie bei einem Partiewechsel, das heißt, wenn an einer Spulmaschine das Garnmaterial gewechselt wird und entsprechend Vorlagespulen in Arbeitsstellen eingeschleust werden, an denen weder ein Oberfaden noch ein Unterfaden vorhanden ist, wirkungslos sind.However, the above-described facilities have the disadvantage so that when there is a change of game, that is, when there is a Spooling machine the yarn material is changed and accordingly Supply spools are introduced into workplaces where there is neither an upper thread nor a lower thread, are ineffective.

Im Falle eines Partiewechsels war daher bislang stets ein manueller Eingriff durch das Bedienpersonal notwendig, um jede einzelne Spulstelle wieder anzufahren.So, in the event of a game change, there has always been one manual intervention by the operating personnel necessary to each to start up individual winding unit again.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die bekannten Arbeitsstellen von Kreuzspulen herstellenden Textilmaschinen weiter zu verbessern.The present invention is based on the aforementioned prior art based on the task, the known jobs of To further improve cross-wound textile machines.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.According to the invention, this object is achieved by a device as described in claim 1.

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

Die erfindungsgemäße Ausführungsform hat insbesondere den Vorteil, daß nach einem Partiewechsel die einzelnen Arbeitsstellen der Kreuzspulen herstellenden Textilmaschinen automatisch, das heißt, ohne jeden manuellen Eingriff seitens des Bedienpersonals wieder in Betrieb genommen werden können.The embodiment according to the invention has in particular the Advantage that after a lot change the individual Workplaces of textile machines producing cross-wound bobbins automatically, that is, without any manual intervention on the part of the Operating personnel can be put back into operation.

Auf diese Weise wird nicht nur die Zeitspanne des Wiederanlaufens des Kreuzspulautomaten erheblich verkürzt und damit der Wirkungsgrad der betreffenden Textilmaschine deutlich erhöht, sondern auch das Bedienpersonal merklich entlastet.This way, not only will the restart period of the automatic winder significantly shortened and thus the The efficiency of the textile machine in question is significantly increased, but also noticeably relieved the operating personnel.

Wie in den Unteransprüchen dargelegt, weist die Vorrichtung in bevorzugter Ausbildung ein zusätzliches, durch einen Schrittmotor definiert, von einer Fadenaufnahmestellung in eine Fadenübergabestellung verschwenkbares Saugrohr auf. Dieses unterdruckbeaufschlagbares Saugrohr nimmt den Faden, der vorher vom Greiferrohr zur Spleißeinrichtung gebracht und durch eine dort angeordnete Schneideinrichtung getrennt wurde, und der dann auf einer Zwischenablage, das heißt einem im Bereich des Fadenspanners angeordnetem Lagerblech liegt, automatisch auf und transportiert ihn zu einer im Bereich des Spulenrahmens angeordneten Klemm- und Schneideinrichtung, die den Faden anschließend zur Übergabe an die Leerhülse bereitlegt.As set out in the subclaims, the device in preferred training an additional, by a stepper motor defined, from a thread take-up position into a Thread transfer position swiveling suction pipe. This Suction tube that can be pressurized takes the thread that was previously brought from the gripper tube to the splicer and through a cutting device arranged there was separated, and then on a clipboard, that is, in the area of the Thread tensioner arranged bearing plate is automatically on and transports it to one in the area of the coil frame arranged clamping and cutting device that the thread then ready for handover to the empty tube.

Weitere Einzelheiten der Erfindung sind einem nachfolgend anhand der Zeichnungen erläuterten Ausführungsbeispiel entnehmbar.Further details of the invention are based on one below of the drawings illustrated embodiment.

In Figur 1 ist in Seitenansicht schematisch eine Arbeitsstelle 2 einer Kreuzspulen herstellenden Textilmaschine, im Ausführungsbeispiel eines Kreuzspulautomaten, dargestellt. Derartige Kreuzspulautomaten weisen üblicherweise zwischen ihren Endgestellen eine Vielzahl solcher gleichartiger Arbeitsstellen, im vorliegenden Fall Spulstellen 2, auf. Auf diesen Spulstellen 2 werden, wie bekannt und daher nicht näher erläutert, die auf einer (nicht dargestellten) Ringspinnmaschine produzierten Spinnkopse 9 zu großvolumigen Kreuzspulen 11 umgespult.A work station 2 is shown schematically in side view in FIG. 1 a cross-wound textile machine, in Embodiment of a cheese winder, shown. Such automatic winding machines usually have between them A large number of such similar jobs, in the present case winding units 2. On these winding units 2 are, as is known and therefore not explained in detail, on produced a ring spinning machine (not shown) Spinning reels 9 rewound to form large-volume cross-wound bobbins 11.

Die während des Spulprozesses in einem schwenkbar gelagerten Spulenrahmen 18 gehalterten Kreuzspulen 11 werden nach ihrer Fertigstellung durch entsprechendes Verschwenken des Spulenrahmens 18 um eine Schwenkachse 19 auf eine Kreuzspulentransporteinrichtung 21 überführt, die hinter den Spulvorrichtungen der Arbeitsstellen 2 angeordnet ist. Über die Kreuzspulentransporteinrichtung 21 werden die Kreuzspulen 11 dann zu einer textilmaschinenendseitig angeordneten (ebenfalls nicht dargestellten) Spulenverladestation oder der gleichen transportiert.The one pivoted during the winding process Bobbin frame 18 held cross bobbins 11 according to their Completion by swiveling the Coil frame 18 about a pivot axis 19 on a Cross coil transport device 21 transferred behind the Spooling devices of the work stations 2 is arranged. About the Cross-wound bobbin transport device 21 then becomes the cross-wound bobbin 11 to a textile machine end (also not shown) coil loading station or the same transported.

Solche Kreuzspulautomaten besitzen in der Regel außerdem eine Logistikeinrichtung in Form eines Spulen- und Hülsentransportsystems 3. In diesem Spulen- und Hülsentransportsystem 3 laufen, auf Transporttellern 8 in vertikaler Ausrichtung positioniert, Spinnkopse 9 beziehungsweise Leerhülsen 9' um.Such automatic winding machines usually also have one 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 in positioned vertically, spinning heads 9 respectively Empty sleeves 9 'around.

Des weiteren verfügen' solche Kreuzspulautomaten meistens über eine Zentralsteuereinheit, die über einen Maschinenbus mit den einzelnen Arbeitsstellenrechnern 39 der Spulstellen 2 verbunden ist. Furthermore, such automatic winding machines usually have a central control unit, which is connected to the individual workstation computers 39 of the winding units 2 connected is.

Von dem vorstehend erwähnten, insgesamt relativ umfangreichen Spulen- und Hülsentransportsystem 3 sind in Figur 1 lediglich die maschinenlange Kopszuführstrecke 4, die hinter den Spulstellen 2 verlaufende, reversierbare Speicherstrecke 5, eine der zu den Spulstellen 2 führenden Quertransportstrecken 6 sowie die Hülsenrückführstrecke 7 dargestellt.Of the above-mentioned, relatively extensive overall Coil and tube transport system 3 are only those in FIG machine-long bobbin feed path 4 behind the winding units 2 running, reversible storage path 5, one of the Winding units 2 leading transverse transport routes 6 and the Sleeve return path 7 shown.

Die über die Kopszuführstrecke 4 angelieferten Spinnkopse 9 werden in Abspulstellungen 10, die sich jeweils im Bereich der Quertransportstrecken 6 an den Spulstellen 2 befinden, zu großvolumigen Kreuzspulen 11 umgespult.
Die einzelnen Arbeitsstellen verfügen hierzu, wie an sich bekannt und daher nicht näher erläutert, über verschiedene Einrichtungen, die einen ordnungsgemäßen Betrieb dieser Arbeitsstellen 2 gewährleisten.
The spinning bobbins 9 delivered via the cop feed section 4 are rewound to large-volume cross-wound bobbins 11 in unwinding positions 10, which are each located in the region of the transverse transport sections 6 at the winding stations 2.
For this purpose, as is known per se and therefore not explained in more detail, the individual workplaces have various facilities which ensure proper operation of these workplaces 2.

In Figur 1 ist beispielsweise mit 12 eine Saugdüse, mit 24 ein Greiferrohr, mit 13 eine Spleißeinrichtung, mit 14 eine Fadenspanneinrichtung, mit 15 ein Fadenreiniger mit Fadenschneideinrichtung sowie mit 16 eine Paraffiniereinrichtung angdeutet.
Der Spulenantrieb, der in der vorliegenden Ausführungsform in ein Lagergehäuse am Spulenrahmen 18 integriert ist, trägt die Bezugszahl 17.
In FIG. 1, for example, 12 denotes a suction nozzle, 24 a gripper tube, 13 a splicing device, 14 a thread tensioning device, 15 a thread cleaner with thread cutting device and 16 a paraffinizing device.
The coil drive, which is integrated in a bearing housing on the coil frame 18 in the present embodiment, bears the reference number 17.

Während des Spulvorganges ist die Kreuzspule 11 in Hülsenaufnahmetellern des Spulenrahmens 18 gehalten und liegt mit ihrer Oberfläche auf einer Stützrolle 20 auf. Die Stützrolle 20 wird dabei von der angetriebenen Kreuzspule 11 über Reibschluß mitgenommen. During the winding process, the cheese 11 is in Sleeve receiving plates of the coil frame 18 held and lies with their surface on a support roller 20. The support roller 20 is driven by the cheese 4 via friction taken.

Im Bereich der Stützrolle 20 ist eine Fadenchangiereinrichtung 22 installiert, wie sie beispielsweise in der DE 198 58 528 A1 beschrieben ist.
Des weiteren weisen die einzelnen Spulstellen 2 im Bereich ihrer Stützrolle 20 jeweils eine definiert ansteuerbare Klemm- und Schneideinrichtung 23 auf.
Solche Klemm- und Schneideinrichtungen sind Gegenstand einer parallelen Patentanmeldung der Anmelderin.
A thread traversing device 22 is installed in the area of the support roller 20, as is described, for example, in DE 198 58 528 A1.
Furthermore, the individual winding units 2 each have a defined controllable clamping and cutting device 23 in the region of their support roller 20.
Such clamping and cutting devices are the subject of a parallel patent application by the applicant.

Wie aus Figur 1 weiter ersichtlich, verfügen die einzelnen Spulstellen 2 über einen spulstelleneigenen
Leerhülsenspeicher 25, der, wie beispielsweise aus der DE 25 57 304 B bekannt, durch den Spulstellenrahmen 18 im Sinne "Leerhülsen entnehmen" beaufschlagbar ist.
As can also be seen from FIG. 1, the individual winding units 2 have their own winding unit
Empty tube memory 25, which, as is known for example from DE 25 57 304 B, can be acted upon by the winding unit frame 18 in the sense of "removing empty tubes".

Erfindungsgemäß ist jede Spulstelle 2 außerdem mit einem definiert ansteuerbaren Saugrohr 1 sowie einem im Bereich des Fadenspanners 14 angeordneten Lagerblech 26 ausgestattet.According to the invention, each winding unit 2 is also provided with one defines controllable intake manifold 1 and one in the area of Thread tensioner 14 arranged bearing plate 26 equipped.

Funktion der Einrichtung:Function of the facility:

Zu Beginn des Spulbetriebes, das heißt, nach einem Partiewechsel, werden die einzelnen Spulstellen 2 des Kreuzspulautomaten zunächst mit Spinnkopsen 9 der neuen Garnpartie versorgt.At the beginning of the winding operation, that is, after changing the lot, the individual winding units 2 of the automatic winder first supplied with spinning heads 9 of the new yarn section.

Das bedeutet, in jede Spulstelle 2 fährt über die Quertransportstrecke 6 wenigstens ein Spinnkops 9 ein, der im Bereich der Spulstelle 2 in einer Abspulstellung 10 fixiert wird.This means that each winding unit 2 runs over the Transverse conveyor 6 at least one spinning cop 9, which in Area of the winding unit 2 is fixed in an unwind position 10.

Anschließend wird der beispielsweise an der Hülsenspitze des Spinnkopses 9 bereitgelegte Faden 28, wie üblich, durch eine im Bereich der Abspulstellung 10 der Arbeitsstelle 2 angeordnete Fadenendlöseeinrichtung 31 nach oben geblasen und vom Greiferrohr 24 aufgenommen.
Daraufhin schwenkt das Greiferrohr 24 in Richtung S nach oben und positioniert den Faden 28, wie ebenfalls bekannt, in einer Spleißeinrichtung 13, die, wie üblich, obere und untere Schneideinrichtungen 30 besitzt.
Subsequently, the thread 28 provided, for example, on the sleeve tip of the spinning cop 9 is, as usual, blown upward by a thread end release device 31 arranged in the region of the unwinding position 10 of the work station 2 and picked up by the gripper tube 24.
The gripper tube 24 then swivels upwards in the direction S and positions the thread 28, as is also known, in a splicing device 13 which, as usual, has upper and lower cutting devices 30.

Durch eine zusätzliche Spulstellenschaltung (siehe Fig.3), bei der die Saugdüse 12 nach oben geschwenkt wird, um den (nicht vorhandenen) Oberfaden zu holen und in die Spleißeinrichtung 13 einzulegen, werden die Schneideinrichtungen 30 der Spleißeinrichtung 13 betätigt und dabei der im Greiferrohr 24 gehaltene Faden 28 abgetrennt. Der Faden 28 fällt daraufhin, wie in Figur 3 angedeutet, auf ein Lagerblech 26, das beispielsweise auf dem Fadenspanner 14 angeordnet ist. Das heißt, das Lagerblech 26 fungiert als Zwischenablage für den abgetrennten Faden 28, der durch das Saugrohr 1 pneumatisch aufgenommen.With an additional winding position switch (see Fig. 3), at the suction nozzle 12 is pivoted upwards to the (not existing) to pick up and into the splicer 13 the cutting devices 30 of the Splicing device 13 is actuated and the one in the gripper tube 24 held thread 28 separated. The thread 28 then falls as indicated in Figure 3, on a bearing plate 26, for example is arranged on the thread tensioner 14. That is, that Bearing plate 26 acts as a clipboard for the separated Thread 28, which is taken up pneumatically by the suction tube 1.

Während das Greiferrohr 24 und die Saugdüse 12 in ihre Ausgangsstellung zurückgeschwenken, wird das Saugrohr 1, das um eine Schwenkachse 32 begrenzt drehbar gelagert ist und mittels eines Schrittmotors 29 lagegenau positionierbar ist, aus der Fadenaufnahmestellung I in die Fadenübergabestellung II verschwenkt und der Faden 28 an eine im Bereich des Spulenrahmens 18 angeordnete, insgesamt mit der Bezugszahl 23 gekennzeichnete Klemm- und Schneideinrichtung übergeben (Figur 4 und 5).While the gripper tube 24 and the suction nozzle 12 in their Swing back the starting position, the intake manifold 1, the a pivot axis 32 is rotatably supported and limited a stepper motor 29 can be positioned precisely from which Thread take-up position I into the thread transfer position II pivoted and the thread 28 to one in the area of Coil frame 18 arranged, overall with the reference number 23 hand over the marked clamping and cutting device (Figure 4 and 5).

Die Klemm- und Schneideinrichtung 23, die, wie in Figur 5 angedeutet, über ein an einem Scherenhebel 36 angeordnetes Klemm/Schneidelement 35 sowie einen Fadenführungshebel 37 verfügt, bearbeitet den Faden 28 derart, daß ein Fadenstrang 38 entsteht. Der Fadenstrang 38 ist dabei, wie in Figur 6 angedeutet, so positioniert, daß er beim Schließen des Spulenrahmens 18 zwischen dem Fuß einer Leerhülse 34, die der Spulenrahmen 18 vorher einem spulstelleneigenen Hülsenspeicher 25 entnommen hat, und einem der Hülsenaufnahmeteller des Spulenrahmens 18 geklemmt wird.The clamping and cutting device 23, which, as in FIG indicated, via a clamping / cutting element arranged on a scissor lever 36 35 and a thread guide lever 37, processes the thread 28 such that a thread strand 38 is formed. The thread strand 38 is, as indicated in FIG. 6, like this positioned that when closing the coil frame 18 between the foot of an empty sleeve 34, which the coil frame 18 previously one has taken its own winding memory 25, and one of the Sleeve receiving plate of the coil frame 18 is clamped.

Das heißt, der Faden der neuen Garnpartie ist an einer neuen Spulenhülse 34 festgelegt. An der betreffenden Spulstelle kann ein neuer Spulprozeß gestartet werden.This means that the thread of the new thread section is on a new one Coil sleeve 34 set. At the winding unit in question a new winding process can be started.
