Description

Die Erfindung betrifft eine Hülsenvorlageeinrichtung für Kreuzspulen herstellende Textilmaschinen gemäß dem Oberbegriff des Anspruches 1.The invention relates to a sleeve presentation device for Textile machines producing cross-wound bobbins according to the generic term of claim 1.

Im Zusammenhang mit Kreuzspulen herstellenden Textilmaschinen, beispielsweise Offenend-Spinnmaschinen oder Spulautomaten, sind verschiedene Einrichtungen und Verfahren bekannt, um die zahlreichen Arbeitsstellen dieser Textilmaschinen ausreichend mit Leerhülsen zu versorgen, die diese Textilmaschinen zum Herstellen neuer Auflaufspulen benötigen.In connection with textile machines producing cross-wound bobbins, for example, open-end spinning machines or automatic winding machines various facilities and processes known to the numerous jobs of these textile machines sufficient to supply with empty tubes that these textile machines for Manufacture new take-up spools.

Durch die DE 25 06 417 C2 ist zum Beispiel eine Hülsenvorlageeinrichtung für eine Textilmaschine bekannt, die über eine maschinenlange, kontinuierlich umlaufende Transportkette mit Transporthaken zur Aufnahme von Leerhülsen verfügt. Im Bereich der Arbeitsstellen der Textilmaschine sind schwenkbar gelagerte Zwischenspeicher angeordnet, die in den Transportweg der Transportkette geschwenkt werden können und in dieser Position jeweils eine neue Leerhülse von der Transportkette absteifen, die dann in den Zwischenspeicher fällt.DE 25 06 417 C2, for example, is one Sleeve feed device for a textile machine known over a machine-long, continuously rotating Transport chain with transport hook for receiving empty tubes features. In the area of workplaces of the textile machine are pivoted intermediate storage arranged in the Transport path of the transport chain can be pivoted and in this position a new empty tube from the Stiffen the transport chain, which is then stored in the buffer falls.

Bei Bedarf entnimmt ein die Arbeitsstellen bedienender Kreuzspulenwechsler die Leerhülse aus dem Zwischenspeicher und wechselt sie in die Spulenrahmen der betreffenden Spulstelle ein. Anschließend wird der Zwischenspeicher wieder in seiner Leerhülsenaufnahmestellung im Bereich des Transportweges der Transportkette positioniert und dort erneut mit einer Leerhülse gefüllt. If necessary, a person taking care of the workplaces Cross coil changer the empty tube from the buffer and it changes into the bobbin frame of the winding unit concerned on. Then the clipboard is back in its Empty sleeve receiving position in the area of the transport route of the Transport chain positioned and there again with an empty sleeve filled.

Die vorbeschriebene Einrichtung hat sich, insbesonders bei Mehrpartienbelegung der Textilmaschinen, als nicht geeignet erwiesen und konnte sich daher in der Praxis nicht durchsetzen.The facility described above has, especially at Multi-lot allocation of the textile machines, as not suitable proven and could therefore not prevail in practice.

Durch die EP 0 262 726 A2 und die DE 195 29 566 A1 sind Einrichtungen Stand der Technik, bei denen die Arbeitsstellen einer Kreuzspulen herstellenden Textilmaschine über ein maschinenlanges Hülsentransportband mit einem maschinenendseitig angeordneten, zentralen Hülsenmagazin verbunden sind. Im Falle eines Kreuzspulenwechsels positioniert sich ein Bedienaggregat an der betreffenden Spulstelle und wechselt die fertiggestellte Kreuzspule gegen eine vorher angeforderte und über das Hülsentransportband angelieferte Leerhülse aus. Die verfahrbaren Bedienaggregate dieser Textilmaschinen weisen dabei Handhabungseinrichtungen auf, mit denen sie die Leerhülse von der Transportbahn aufnehmen und in den Spulenrahmen der Spulstelle einlegen können.Through EP 0 262 726 A2 and DE 195 29 566 A1 State of the art facilities at which the jobs a textile machine producing cross-wound bobbins machine-long sleeve conveyor belt with one central sleeve magazine arranged on the machine end are connected. Positioned in the event of a package change a control unit at the winding unit concerned and the completed bobbin is replaced by a previously requested and delivered via the sleeve conveyor belt Empty sleeve. The movable control units of this Textile machines have handling devices with which they pick up the empty tube from the transport track and in can insert the bobbin frame of the winding unit.

Nachteilig bei diesen bekannten Einrichtungen ist vor allem, daß der an der Arbeitsstelle positionierte Kreuzspulenwechsler zunächst die Ankunft einer angeforderten Leerhülse abwarten muß. Die dabei auftretenden Wartezeiten wirken sich negativ auf den Gesamtwirkungsgrad dieser Textilmaschinen aus.A disadvantage of these known devices is, above all, that the package changer positioned at the place of work first wait for the arrival of a requested empty tube got to. The waiting times that occur have a negative effect the overall efficiency of these textile machines.

Um diese Wartezeiten zu vermeiden, ist in der Vergangenheit bereits vorgeschlagen worden, im Bereich der Arbeitsstellen Zwischenspeicher vorzusehen, die über das Hülsentransportband mit Leerhülsen versorgt werden. Aus diesen Zwischenspeichern kann der Kreuzspulenwechsler dann jederzeit eine Leerhülse entnehmen und sofort in den Spulenrahmen einwechseln.To avoid these waiting times is in the past already been proposed in the field of jobs To provide temporary storage over the sleeve conveyor belt be supplied with empty tubes. From these caches the package changer can then always have an empty tube remove and replace immediately in the coil frame.

In der DE 195 12 891 A1 oder der DE 195 21 372 A1 sind ebenfalls Einrichtungen beschrieben, bei denen die Textilmaschinen über ein maschinenendseitig angeordnetes, zentrales Hülsenmagazin verfügen. Das Hülsenmagazin ist dabei, wie bekannt, über ein maschinenlanges Hülsentransportband mit den arbeitsstelleneigenen Zwischenspeichern verbunden.In DE 195 12 891 A1 or DE 195 21 372 A1 also described facilities where the Textile machines via a machine end central sleeve magazine. The sleeve magazine is about as is known, with a machine-long sleeve conveyor belt connected to the job-specific temporary storage.

Die Kreuzspulenwechsler dieser Textilmaschinen weisen sowohl einen Handhabungsmechanismus zum Überführen der Leerhülsen vom Hülsentransportband in die Zwischenspeicher als auch eine Handhabungseinrichtung zum Aufnehmen und Einwechseln der in den Zwischenspeichern deponierten Leerhülsen in den Spulenrahmen der betreffenden Spulstellen auf.
Bei diesen bekannten Einrichtungen wird zu Beginn des Kreuzspulenwechselvorganges durch das Bedienaggregat sofort eine neue Leerhülse angefordert, die das Bedienaggregat, bevor es die Spulstelle wieder verläßt, in den Zwischenspeicher der Spulstelle überführt.
The cross-wound bobbin changers of these textile machines have both a handling mechanism for transferring the empty tubes from the tube conveyor belt into the intermediate store and a handling device for receiving and changing the empty tubes deposited in the intermediate stores in the bobbin frame of the relevant winding units.
In these known devices, a new empty tube is immediately requested by the operating unit at the beginning of the package change process, which transfers the operating unit to the intermediate storage unit of the winding unit before it leaves the winding unit.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine verbesserte Hülsenvorlageeinrichtung zu schaffen, d.h. eine Hülsenvorlageeinrichtung, bei der die Übergabe von Leerhülsen vom Hülsenzentralmagazin zu den Hülsenzwischenspeichern auf eine alternative Weise bewerkstelligt wird.Based on the aforementioned prior art, the Invention based on the object, an improved To create sleeve feed means, i.e. a Tube feed device, in which the transfer of empty tubes from the central sleeve magazine to the intermediate sleeve stores an alternative way is accomplished.

Diese Aufgabe wird erfindungsgemäß durch eine Einrichtung 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 Dependent claims.

Die erfindungsgemäße Ausführungsform hat dabei den Vorteil, daß die Hülsenvorlageeinrichtung, die im wesentlichen aus einer stationären, horizontal verlaufenden, fensterartige Ausnehmungen aufweisenden Bahn, einem entlang dieser Bahn verschiebbar gelagerten, ebenfalls fensterartige Ausnehmungen besitzenden Steuerband sowie einem an der Bahn verfahrbaren Hülsentransportwagen besteht, wobei sowohl die horizontal verlaufende Bahn als auch das Steuerband aus einem ferromagnetischen Werkstoff, vorzugsweise Stahl, gefertigt sind, nur wenige, relativ robuste Bauteile aufweist. Eine solche Ausbildung läßt nicht nur eine hohe Lebensdauer der Einrichtung erwarten, sondern führt auch zu einem guten Preis-/Leistungsverhältnis der Einrichtung.The embodiment of the invention has the advantage that the sleeve feed device, which consists essentially of a stationary, horizontal, window-like Recessing path, one along this path slidably mounted, also window-like recesses possessing control band as well as a movable on the train Sleeve transport trolley exists, both the horizontal running web as well as the control band from one ferromagnetic material, preferably steel are, has only a few, relatively robust components. A such training not only leaves a long life Expect establishment, but also leads to a good one Price / performance ratio of the facility.

Die erfindungsgemäße Hülsenvorlageeinrichtung zeichnet sich aufgrund ihres konstruktiven Aufbaues außerdem durch eine hohe Funktionalität und eine gute Verfügbarkeit aus. Insbesondere die Art der Ansteuerung der am Hülsentransportwagen angeordneten Hülsengreifeinrichtung hat sich als sehr zuverlässig und nahezu verschleißfrei erwiesen.The sleeve feed device according to the invention stands out due to their constructive structure also by a high Functionality and good availability. In particular the type of control on the sleeve transport trolley arranged sleeve gripping device has proven to be very proven reliable and almost wear-free.

Ein weiterer Vorteil der Einrichtung ist darin zu sehen, daß jederzeit und nahezu problemlos auch eine Nachrüstung bereits ausgelieferter Textilmaschinen mit der erfindungsgemäßen Hülsenvorlageeinrichtung möglich ist.Another advantage of the facility is that Retrofitting at any time and almost without any problems delivered textile machines with the invention Sleeve feed device is possible.

Die Bahn und das Steuerband weisen dabei, wie vorstehend bereits angedeutet, eine Vielzahl von fensterartigen Ausnehmungen auf, deren Abmeßungen und Abstände jeweils übereinstimmen. Die Positionen der in der stationären Bahn angeordneten Ausnehmungen ergeben sich dabei aus der Spulstellenteilung der Textilmaschine, wobei diese Spulstellenteilung auch die Teilung der Speicherkolumnen des Hülsenzentralmagazins bestimmt.
Eine solche Ausführungsform ermöglicht es auf einfache und vorteilhafte Weise, sowohl im Bereich der spulstelleneigenen Zwischenspeicher als auch im Bereich der Speicherkolumnen des zentralen Hülsenmagazins jederzeit magnetisierbare oder nichtmagnetisierbare Zonen zu schaffen, die in Verbindung mit einer entsprechenden, am Hülsentransportwagen angeordneten Permanentmagnetpaketanordnung für einen Steuerungsvorgang der Hülsengreifeinrichtung dieses Transportmittels benutzt werden können. Das heißt, durch entsprechende Positionierung der Ausnehmungen des entlang der Bahn verschiebbar gelagerten Steuerbandes kann im Bedarfsfall ein am Hülsentransportwagen angeordnetes Permanentmagnetpaket aktiviert und damit die Hülsengreifeinrichtung des Hülsentransportwagens zuverlässig und schnell betätigt werden.
As already indicated above, the web and the control band have a large number of window-like recesses, the dimensions and spacings of which correspond. The positions of the recesses arranged in the stationary path result from the winding position division of the textile machine, this winding position division also determining the division of the storage columns of the central sleeve magazine.
Such an embodiment makes it possible, in a simple and advantageous manner, to create magnetizable or non-magnetizable zones at any time both in the area of the bobbin-specific buffer stores and in the area of the storage columns of the central sleeve magazine, which zones in connection with a corresponding permanent magnet package arrangement arranged on the sleeve transport carriage for a control process of the sleeve gripping device this means of transport can be used. That is, by appropriately positioning the recesses of the control belt slidably mounted along the track, a permanent magnet package arranged on the sleeve transport carriage can be activated if necessary, and the sleeve gripping device of the sleeve transport carriage can thus be actuated reliably and quickly.

Das Steuerband ist dabei, wie im Anspruch 2 beschrieben, an ein Schubkolbengetriebe angeschlossen, das, wie üblich, zwei definierte Endstellungen aufweist. Die Endstellungen des Schubkolbengetriebes entsprechen dabei jeweils einer ersten beziehungsweise zweiten Steuerstellung des Steuerbandes.
Im Zusammenhang mit der Positionierung des Steuerbandes sind daher keine weiteren zusätzlichen Steuereinrichtungen mehr nötig.
The control belt is, as described in claim 2, connected to a thrust piston gear, which, as usual, has two defined end positions. The end positions of the thrust piston transmission each correspond to a first or second control position of the control belt.
In connection with the positioning of the control band, no further additional control devices are therefore necessary.

Vorzugsweise ist das Steuerband in seiner ersten Steuerstellung bezüglich der stationären Bahn derart positioniert, daß, wie im Anspruch 3 dargelegt, die fensterartigen Ausnehmungen des Steuerbandes deckungsgleich mit den entsprechenden Ausnehmungen der horizontal verlaufenden Bahn angeordnet sind.
Die Ausnehmungen der Bahn und die Ausnehmungen des Steuerbandes stehen dabei mittig zu den Speicherkolumnen des Hülsenzentralmagazins bzw. mittig zu den spulstelleneigenen Hülsenzwischenspeichern. Das heißt, in der ersten Steuerstellung des Steuerbandes sind diese Bereiche stets frei von ferromagnetischem Werkstoff, so daß dort eine nichtmagnetisierbare Zone gegeben ist.
The control band is preferably positioned in its first control position with respect to the stationary path such that, as stated in claim 3, the window-like recesses of the control band are arranged congruently with the corresponding recesses of the horizontally running path.
The recesses of the web and the recesses of the control belt are in the middle of the storage columns of the central sleeve magazine or in the middle of the winding station's own intermediate buffers. This means that in the first control position of the control band, these areas are always free of ferromagnetic material, so that there is a non-magnetizable zone.

Die zweite Steuerstellung, die im Anspruch 4 beschrieben ist, führt hingegen zu einer durchgängig ferromagnetischen Zone im Bereich der horizontal verlaufenden Bahn, da das Steuerband in dieser Steuerstellung gegenüber der Bahn derart axial verlagert ist, daß alle Ausnehmungen der Bahn durch das Steuerband vollständig abgedeckt werden.The second control position, which is described in claim 4, leads to a continuous ferromagnetic zone in the Area of the horizontal path, since the control band in axially shifted this control position relative to the web is that all the recesses of the web through the control band be completely covered.

In vorteilhafter Ausbildung ist der an der Bahn verfahrbar angeordnete Hülsentransportwagen, der eine magnetisch aktivierbare Hülsengreifeinrichtung aufweist, über ein Zugmittel, gemäß Anspruch 6 einen Endlos-Zahnriemen, mit einem reversierbaren Elektro-Antrieb verbunden (Anspruch 5).In an advantageous embodiment, it can be moved on the track arranged sleeve transport carriage, one of which is magnetic has activatable sleeve gripping device, via a Traction means, according to claim 6, an endless toothed belt, with a reversible electric drive connected (claim 5).

Da der Endlos-Zahnriemen formschlüssig auf einem Antriebsritzel des Elektro-Antriebes geführt ist und die Antriebseinrichtung außerdem, wie im Anspruch 7 dargelegt, eine hoch auflösende Sensoreinrichtung, beispielsweise einen Inkrementalgeber, aufweist, kann der Hülsentransportwagen einerseits mit hoher Geschwindigkeit die Hülsenaufnahmestellungen im Bereich des zentralen Hülsenmagazins und/oder die Hülsenabgabestellungen an den spulstelleneigenen Hülsenzwischenspeichern anfahren und anderseits dort dennoch stets sehr schnell und sehr exakt positioniert werden.Because the endless toothed belt fits positively on a drive pinion of the electric drive and the drive device moreover, as set out in claim 7, a high resolution Sensor device, for example an incremental encoder, has, the sleeve transport carriage on the one hand with high Speed the sleeve receiving positions in the range of central sleeve magazine and / or the sleeve delivery positions move to the winding unit's own sleeve buffers and on the other hand, it is always very quick and very precise be positioned.

In bevorzugter Ausbildung (Anspruch 8) besteht die Hülsengreifeinrichtung des Hülsentransportwagens aus zwei schwenkbar gelagerten Greiferarmen. Die beispielsweise als zweiarmige Greiferarme ausgebildeten Hülsenhandhabungselemente sind dabei über ein Federstahlband derart gekoppelt, daß die Greiferarme bei unbelastetem Federstahlband in einer sogenannten Hülsenaufnahmestellung stehen. Die Greiferarme werden dabei außerdem durch Federelemente zusätzlich im Sinne "öffnen" beaufschlagt (Anspruch 9). In a preferred embodiment (claim 8) Sleeve gripping device of the sleeve transport carriage from two swiveling gripper arms. For example, as two-armed gripper arms formed sleeve handling elements are coupled via a spring steel strip in such a way that the Gripper arms in an unloaded spring steel band in one so-called sleeve receiving position. The gripper arms are also in the sense of spring elements "Open" applied (claim 9).

Wie im Anspruch 10 beschrieben, ist am Federstahlband ein Permanentmagnetpaket festgelegt, das in Verbindung mit einem ferromagnetischen Gegenpol zur Auslenkung des Federstahlbandes und damit zum Schließen der Hülsengreifeinrichtung benutzt werden kann. Das heißt, durch magnetisch initiiertes seitliches Auslenken des Federstahlbandes können die Greiferarme zuverlässig in eine Schließstellung, in der eine zwischen den Greiferarmen positionierte Leerhülse sicher fixiert ist, überführt werden. Dabei wird das Bestreben des Permanentmagnetpakets, sich stets an einen magnetisierbaren Gegenpol, z. B. die ferromagnetische Bahn oder das ebenfalls ferromagnetische Steuerband anzulegen, ausgenutzt.
Die Dimensionierung des zwischen die Greiferarme eingeschalteten Federstahlbandes sowie dessen Abstand zur horizontal verlaufenden Bahn ist dabei vorteilhafterweise so gewählt, daß ein direktes Anlegen des Permanentmagnetpaketes an den ferromagnetischen Gegenpol zuverlässig vermieden wird.
As described in claim 10, a permanent magnet package is fixed to the spring steel band, which can be used in conjunction with a ferromagnetic counter pole to deflect the spring steel band and thus to close the sleeve gripping device. This means that by magnetically initiated lateral deflection of the spring steel band, the gripper arms can be reliably transferred into a closed position in which an empty sleeve positioned between the gripper arms is securely fixed. The endeavor of the permanent magnet package is always to a magnetizable opposite pole, for. B. to use the ferromagnetic track or the ferromagnetic control band, exploited.
The dimensioning of the spring steel strip connected between the gripper arms and its distance from the horizontally running path is advantageously chosen so that a direct application of the permanent magnet package to the ferromagnetic opposite pole is reliably avoided.

In Fig. 1 ist in Vorderansicht schematisch eine insgesamt mit der Bezugszahl 1 gekennzeichnete Spulmaschine dargestellt. Derartige Spulmaschinen 1 weisen üblicherweise zwischen ihren Maschinenendgestellen 2 und 3 eine Vielzahl gleichartiger Spulstellen 4 auf. Auf diesen Spulstellen 4 werden, wie bekannt und daher nicht näher erläutert, die auf einer (nicht dargestellten) Ringspinnmaschine produzierten Spinnkopse 22 zu großvolumigen Kreuzspulen 5 umgespult.
Die fertiggestellten Kreuzspulen 5 werden mittels einer selbsttätig arbeitenden Bedienvorrichtung, zum Beispiel mittels eines Kreuzspulenwechslers 6, auf ein Kreuzspulentransportband 7 ausgeschoben und zu einer maschinenendseitig angeordneten (nicht dargestellten) Spulenverladeeinrichtung oder dergleichen transportiert.
In Fig. 1 a front view of a winder generally identified with the reference number 1 is shown schematically. Such winding machines 1 usually have a large number of similar winding stations 4 between their machine end frames 2 and 3. On these winding units 4, as is known and therefore not explained in detail, the spinning bobbins 22 produced on a ring spinning machine (not shown) are rewound to form large-volume cross-wound bobbins 5.
The finished cross-wound bobbins 5 are pushed out by means of an automatically operating operating device, for example by means of a cross-wound bobbin changer 6, onto a cross-wound bobbin conveyor belt 7 and transported to a bobbin loading device or the like arranged on the machine end (not shown).

Der oberhalb der Arbeitsstellen 4 verfahrbar angeordnete Kreuzspulenwechsler 6 sorgt dabei nicht nur dafür, daß die auf den Spulstellen 4 fertiggestellten Kreuzspulen 5 auf das Kreuzspulentransportband 7 ausgeschoben werden, sondern er wechselt auch jeweils selbsttätig eine Hülse 8 in den Spulenrahmen der betreffenden Spulstelle 4 ein. Die entsprechende Hülse 8 entnimmt er dabei einem spulstelleneigenen Hülsenzwischenspeicher 9, der über eine maschinenlange Transporteinrichtung 10 mit einem maschinenendseitig angeordneten Hülsenzentralmagazin 11 der Spulmaschine 1 verbunden ist.The one arranged above the work stations 4 so as to be movable Cross-coil changer 6 not only ensures that the on the winding units 4 finished packages 5 on the Cross coil conveyor belt 7 are pushed out, but he also automatically changes a sleeve 8 in each Coil frame of the relevant winding unit 4. The he takes the corresponding sleeve 8 from a winding station's own sleeve buffer 9, which has a machine-long transport device 10 with a sleeve central magazine 11 on the machine end side Winding machine 1 is connected.

Das in den Figuren 1 und 2 angedeutete, insgesamt mit 11 bezeichnete Hülsenzentralmagazin besteht im wesentlichen aus einer Zentraleinheit 50, mit der zentralmagazineigenen Steuereinrichtung 30 und einem vertikal verfahrbaren Greiferschlitten 16 sowie einer an der Zentraleinheit 50 auswechselbar festgelegten Speichereinheit 51. Die Speichereinheit 51 weist dabei mehrere, nebeneinander angeordnete Speicherkolumnen 12, 13, 14, 15 auf, die ihrerseits jeweils eine Anzahl übereinander angeordneter Hülsenaufnahmereihen, sogenannte Beschickungsschächte, für konische und/oder zylindrische Leerhülsen 8 aufweisen.The indicated in Figures 1 and 2, a total of 11 designated central sleeve magazine consists essentially of a central unit 50, with the central magazine Control device 30 and a vertically movable Gripper slide 16 and one on the central unit 50 removable storage unit 51. The Storage unit 51 has several, side by side arranged storage columns 12, 13, 14, 15, which in turn a number of one above the other Series of sleeves, so-called loading chutes, for have conical and / or cylindrical empty sleeves 8.

Das Hülsenzentralmagazin 11 ist über den vertikal verfahrbaren Greiferschlitten 16, der, wie in Fig. 2 angedeutet, im Bereich der Speicherkolumnen 12 - 15 jeweils einen definiert ansteuerbaren Hülsengreifer 17 aufweist, funktional mit der Hülsentransporteinrichtung 10 verbunden.The central sleeve magazine 11 is above the vertically movable Gripper slide 16, which, as indicated in Fig. 2, in the area each of the storage columns 12-15 defines one controllable sleeve gripper 17, functional with the Sleeve transport device 10 connected.

Die U-förmig ausgebildete Bahn 18 ist aus einem ferromagnetischen Werkstoff, zum Beispiel Stahl, gefertigt und weist eine Vielzahl fensterartiger Ausnehmungen 23 auf. Die Ausnehmungen 23 sind dabei jeweils mittig zu den Spulstellen 4 der Spulmaschine 1 und damit mittig zu den dort angeordneten Hülsenzwischenspeichern 9 sowie mittig zu den Speicherkolumnen 12 - 15 des Hülsenzentralmagazins 11 angeordnet.The U-shaped path 18 is made of one ferromagnetic material, for example steel, manufactured and has a plurality of window-like recesses 23. The Recesses 23 are each centered on the winding units 4 the winding machine 1 and thus in the center of those arranged there Sleeve buffers 9 and in the middle of the Storage columns 12 - 15 of the central sleeve magazine 11 arranged.

Das Steuerband 19, das ebenfalls aus einem ferromagnetischen Material gefertigt ist, weist ähnliche fensterartige Ausnehmungen 24 auf, die in ihren Abmeßungen den Ausnehmungen 23 der Bahn 18 entsprechen. Die Ausnehmungen 23, 24 besitzen dabei die gleichen gegenseitigen Abstände. Vorzugsweise sind die Ausnehmungen 24 des Steuerbandes 19 außerdem, aus Unfallschutzgründen, mit einem gitterartigen Fingerschutz versehen. Das Steuerband 19, das über Führungseinrichtungen 36 an der Bahn 18 verschiebbar gelagert ist, kann durch ein Schubkolbengetriebe 25 zwischen einer Steuerstellung A und einer Steuerstellung B (in den Figuren 6 und 7 dargestellt) verschoben werden.The control band 19, which is also made of a ferromagnetic Material is made, has similar window-like Recesses 24 on the dimensions of the recesses 23 correspond to track 18. The recesses 23, 24 have the same mutual distances. Are preferred the recesses 24 of the control band 19 also from Accident protection reasons, with a grid-like finger protection Mistake. The control band 19, which via guide devices 36 is slidably mounted on the track 18 can by a Thrust piston gear 25 between a control position A and a control position B (shown in FIGS. 6 and 7) be moved.

Der Hülsentransportwagen 20, der ein Fahrwerk 37, dessen Räder 38 sich am Innenprofil 39 der Horizontalbahn 18 abstützen, aufweist, ist über ein Zugmittel 26, vorzugsweise einen Endlos-Zahnriemen, an einen reversierbaren Elektro-Antrieb 27 angeschlossen. Die Anbindung des Hülsentransportwagens 20 an das Endlos-Zugmittel 26 erfolgt dabei über eine am Fahrgestell 40 des Hülsentransportwagens 20 angeordnete Anschlußkonsole 41. Am Fahrwerk 40 ist außerdem eine zangenartige Hülsengreifeinrichtung 21 festgelegt, deren Greiferarme 31, 32 in Schwenkachsen 42 begrenzt schwenkbar gelagert sind.The sleeve transport carriage 20, the chassis 37, the Wheels 38 on the inner profile 39 of the horizontal track 18 support, has, is preferably a traction means 26 an endless toothed belt, on a reversible one Electric drive 27 connected. The connection of the Sleeve transport carriage 20 to the endless traction means 26 thereby via one on the chassis 40 of the sleeve transport carriage 20 arranged connection console 41. On the chassis 40 is also a pincer-like sleeve gripping device 21, whose Gripper arms 31, 32 can be pivoted to a limited extent in pivot axes 42 are stored.

Die vorzugsweise abgewinkelten Greiferarme 31, 32 sind über ein Federstahlband 33, an dem ein Permanentmagnetpaket 35 befestigt ist, verbunden. Außerdem sind an den Greiferarmen 31, 32 jeweils Federelemente 34 angelenkt, die die Greiferarme 31, 32 im Sinne "öffnen" beaufschlagen.The preferably angled gripper arms 31, 32 are over a Spring steel strip 33 to which a permanent magnet package 35 is attached is connected. In addition, the gripper arms 31, 32 each spring elements 34 articulated, the gripper arms 31, 32nd act in the sense of "open".

Funktion der Einrichtung:Function of the facility:

Die Spulmaschine 1 befindet sich in einem betriebsbereitem Zustand.
Die Speicherkolumnen 12 - 15 des Hülsenzentralmagazins 11 sind mit Leerhülsen 8 gefüllt.
Über die Eingabetastatur 43 des Hülsenzentralmagazins 11 wird die Steuereinrichtung 30 entsprechend dem gewünschten Beschickungsprogramm eingestellt.
The winding machine 1 is in an operational state.
The storage columns 12-15 of the central sleeve magazine 11 are filled with empty sleeves 8.
The control device 30 is set in accordance with the desired loading program via the input keyboard 43 of the central sleeve magazine 11.

Der Hülsentransportwagen 20 führt daraufhin zunächst in eine 0-Stellung im Bereich des Elektroantriebes 27 und wird dort mittels einer Sensoreinrichtung 29, beispielsweise mittels eines hoch auflösenden Inkrementalgebers, einjustiert. Gleichzeitig fährt der Greiferschlitten 16 in der Zentraleinheit 50 des Hülsenzentralmagazins 11 die vorbestimmte Hülsenaufnahmereihe des Hülsenzentralmagazins 11 an (pro Speicherkolumne sind beispielsweise jeweils acht bis zehn Hülsenaufnahmereihen übereinander angeordnet). Einer der Hülsengreifer 17 des Greiferschlittens 16 nimmt aus der ausgewählten Hülsenaufnahmereihe eine Leerhülse 8 und übergibt sie an die Hülsengreifereinrichtung 21 des inzwischen oberhalb der betreffenden Speicherkolumne 12 - 15 des Hülsenzentralmagazins 11 positionierten Hülsentransportwagens 20.The sleeve transport carriage 20 then leads first into one 0 position in the area of the electric drive 27 and there by means of a sensor device 29, for example by means of of a high-resolution incremental encoder. At the same time, the gripper carriage 16 moves in the Central unit 50 of the sleeve central magazine 11 the predetermined Sleeve receiving series of the sleeve central magazine 11 (per Storage columns are, for example, eight to ten each Rows of sleeves arranged one above the other). One of Sleeve gripper 17 of the gripper carriage 16 takes out of the selected sleeve receiving row an empty tube 8 and passes them to the sleeve gripper device 21 in the meantime above the relevant storage column 12 - 15 des Sleeve central magazine 11 positioned sleeve transport carriage 20th

Das Steuerband 19 steht zu diesem Zeitpunkt in der Steuerstellung A (siehe Figuren 5 und 6), in der die Ausnehmungen 23 der Bahn 18 und die Ausnehmungen 24 des Steuerbandes 19 übereinanderstehen. Da dem an der Hülsengreifeinrichtung 21 des Hülsentransportwagens 20 angeordneten Permanentmagnetpaket 35 in der Steuerstellung A des Steuerbandes 19 kein ferromagnetischer Gegenpol gegenübersteht, bleibt das Permenentmagnetpaket 35 deaktiviert und die Greiferarme 31, 32, die durch Federelemente 34 im Sinne "öffnen" beaufschlagt werden, bleiben geöffnet. Das heißt, die Hülsengreifeinrichtung 21 des Hülsentransportwagens 20 ist in der Steuerstellung A des Steuerbandes bereit zur Übernahme einer Leerhülse 8.The control band 19 is at this time in the Control position A (see Figures 5 and 6), in which the Recesses 23 of the web 18 and the recesses 24 of the Control tape 19 are one above the other. Because of that Sleeve gripping device 21 of the sleeve transport carriage 20 arranged permanent magnet package 35 in the control position A the control band 19 no ferromagnetic counter pole faces, the Permenentmagnetpaket 35 remains deactivated and the gripper arms 31, 32 by spring elements 34 in the sense "open", remain open. That is, the Sleeve gripping device 21 of the sleeve transport carriage 20 is in the tax position A of the tax band ready for takeover an empty tube 8.

Sobald der betreffende Hülsengreifer 17 des Greiferschlittens 16 die aus einer Hülsenaufnahmereihe einer der Speicherkolumnen 12 - 15 abgeholte Hülse 8 zwischen den Greiferarmen 31, 32 der Hülsengreifeinrichtung 21 des Transportwagens 20 positioniert hat, wird das Steuerband 19 in die Steuerstellung B (siehe Figur 7) verlagert. Das bedeutet, das Steuerbandes 19 wird so weit axial verschoben bis die Ausnehmungen 23 in der Bahn 18 durch das ferromagnetische Steuerband 19 vollständig geschlossen sind.As soon as the relevant sleeve gripper 17 of the Gripper slide 16 from a row of receptacles the storage columns 12 - 15 picked sleeve 8 between the Gripper arms 31, 32 of the sleeve gripping device 21 of the Transport vehicle 20 has positioned, the control belt 19 in the control position B (see Figure 7) shifted. That means, the control band 19 is axially displaced until the Recesses 23 in the path 18 through the ferromagnetic Control band 19 are completely closed.

Durch das Schließen der Ausnehmungen 23 der Bahn 18 ergibt sich im Bereich der Bahn 18 eine durchgehend ferromagnetische, das heißt, magnetaktivierende Zone.
Das Permanentmagnetpaket 35 des Hülsentransportwagens 20 versucht sofort sich an diesen ferromagnetischer Gegenpol anzulegen, so daß unter der Magnetkraft des Permanentmagnetpaketes 35 das Federstahlband 33 in Richtung R ausgelegt wird und die Greiferarme 31, 32 in Richtung S verschwenkt werden. Die in Richtung S einschwenkenden Greiferarme 31, 32 fixieren dabei die Leerhülse 8 zwischen sich.
Closing the recesses 23 of the web 18 results in a continuously ferromagnetic, that is to say magnet-activating, zone in the region of the web 18.
The permanent magnet package 35 of the sleeve transport carriage 20 immediately tries to contact this ferromagnetic opposite pole, so that under the magnetic force of the permanent magnet package 35 the spring steel strip 33 is laid out in the R direction and the gripper arms 31, 32 are pivoted in the S direction. The gripper arms 31, 32 pivoting in the direction S fix the empty sleeve 8 between them.

Ders Hülsentransportwagen 20 wird anschließend sofort mit hoher Geschwindigkeit zum Hülsenzwischenspeicher 9 der ausgewählten Spulstelle 4 befördert und dort exakt oberhalb des Hülsenzwischenspeichers 9 positioniert. Im Anschluß daran wird das Steuerband 19 in die Steuerstellung A zurückgeschaltet, das heißt, die Zone vor dem Permanentmagnetpaket 35 des Hülsentransportwagens 20 wird nichtmagnetisierbar gemacht.
Das Permanetmagnetpaket 35 verliert dadurch seinen ferromagnetischen Gegenpol, so daß die Greiferarme 31, 32 unter der Kraft der Federelemente 34 in eine Hülsenabgabestellung zurückgeschwenkt werden. Die Hülse 8 fällt daraufhin in den Hülsenzwischenspeicher 9 der betreffenden Spulstelle 4.
The tube transport carriage 20 is then immediately conveyed at high speed to the tube buffer 9 of the selected winding unit 4 and positioned there exactly above the tube buffer 9. Subsequently, the control belt 19 is switched back to the control position A, that is, the zone in front of the permanent magnet package 35 of the sleeve transport carriage 20 is made non-magnetizable.
The permanent magnet package 35 thereby loses its ferromagnetic opposite pole, so that the gripper arms 31, 32 are pivoted back into a sleeve delivery position under the force of the spring elements 34. The sleeve 8 then falls into the intermediate sleeve store 9 of the winding unit 4 in question.

Der Hülsentransportwagen 20 kehrt jetzt unmittelbar in seine Ausgangslage zurück, das heißt, er fährt in seine 0-Position im Bereich des Elektro-Antriebes 27. Der neu justierte Hülsentransportwagen 20 steht anschließend für den nächsten Hülsentransportvorgang bereit.The sleeve transport carriage 20 now returns immediately to his Starting position back, that is, it moves to its 0 position in Area of the electric drive 27. The newly adjusted Sleeve transport trolley 20 then stands for the next one Sleeve transport process ready.
