Description

Die Erfindung bezieht sich auf eine, entlang einer Spulmaschine verfahrbare Vorrichtung zur Übergabe des Fadenanfangs einer Spule bzw. eines Cops von der Spulenhülse an eine vorbestimmte, durch ein mittels eines Betätigungsglieds verstellbares Verschlußglied abdeckbare Saugöffnung einer Spulmaschine, wobei der Fadenanfang vor der Übergabe in die der Vorrichtung zugekehrte freie Spulenöffnung hineinragt und über einen Saugkanal die freie Spulenöffnung mit der Saugöffnung der Spulmaschine pneumatisch verbindbar ist. Eine derartige Vorrichtung ist durch die DE-A-3 245 326 (z. B. Fig. 7) bekannt geworden.The invention relates to a device which can be moved along a bobbin winder for transferring the beginning of the thread of a bobbin or a cop from the bobbin tube to a predetermined suction opening of a bobbin winder which can be covered by a closing element which can be adjusted by means of an actuating member, the beginning of the thread before being transferred to the Device facing free spool opening protrudes and the free spool opening can be pneumatically connected to the suction opening of the winding machine via a suction channel. Such a device has become known from DE-A-3 245 326 (e.g. Fig. 7).

Bei der vorbekannten Vorrichtung benötigt die Spulmaschine an jeder Saugstelle einen Saugkanal und damit eine entsprechend hohe Saugleistung, um die notwendige Saugwirkung erzeugen zu können. Des weiteren muß die fahrbare Vorrichtung zum Schwenken des Saugkanals bzw. zur Übergabe des Fadenanfangs an jeder Spulstelle mit zusätzlichen Hebeln gekuppelt werden, welche die Steuerbefehle von einem Steueraggregat über ein Gestänge auf die verschiedenen Einrichtungen im Bereich des jeweiligen Spulenbehälters übertragen. Dies erfordert an der Spulmaschine einen entsprechend hohen baulichen Aufwand. Damit ist zwangsläufig auch eine entsprechend große Störanfälligkeit verbunden.In the previously known device, the winder requires a suction channel at each suction point and thus a correspondingly high suction power in order to be able to produce the necessary suction effect. Furthermore, the mobile device for pivoting the suction channel or for transferring the beginning of the thread must be coupled to each winding unit with additional levers which transmit the control commands from a control unit via a linkage to the various devices in the area of the respective bobbin case. This requires a correspondingly high structural outlay on the winding machine. This is inevitably associated with a correspondingly high susceptibility to faults.

Die Aufgabe der Erfindung besteht infolgedessen darin, eine Vorrichtung der eingangs beschriebenen Art so weiterzubilden, daß der bauliche Aufwand der Spulmaschine, an welcher sie verfahrbar gelagert ist, verringert werden kann, um dadurch die Störanfälligkeit zu reduzieren.The object of the invention is therefore to develop a device of the type described in the introduction so that the structural complexity of the winding machine on which it is movably mounted can be reduced, thereby reducing the susceptibility to faults.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß die fahrbare Vorrichtung zur Übergabe des Fadenanfangs einer Spule bzw. eines Cops von der Spulenhülse an eine vorbestimmte Saugöffnung einer Spulmaschine gemäß dem Oberbegriff des Anspruchs 1 entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet ist.To achieve this object it is proposed according to the invention that the mobile device for transferring the beginning of the thread of a bobbin or a cop from the bobbin tube to a predetermined suction opening of a winder is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim.

Bei dieser Vorrichtung befindet sich der Saugkanal an einem Saugglied der Vorrichtung, so daß für sämtliche Spulstellen der Spulmaschine lediglich noch ein einziger Saugkanal erforderlich ist. Dies bringt im Hinblick auf die zu erzeugende Saugwirkung zweifellos Vorteile mit sich. Weil die notwendigen Einrichtungen im Bereich des Spulenbehälters der Vorrichtung zugeordnet sind, erreicht man in der angestrebten Weise einerseits eine bauliche Vereinfachung der Spulmaschine und andererseits durch die Beschränkung auf lediglich eine einzige Vorrichtung eine wesentliche Reduzierung der Störanfälligkeit.In this device, the suction channel is located on a suction member of the device, so that only a single suction channel is required for all winding positions of the winding machine. This undoubtedly has advantages with regard to the suction effect to be generated. Because the necessary devices in the area of the bobbin case are assigned to the device, the desired manner is achieved on the one hand to simplify the construction of the winding machine and on the other hand to limit the susceptibility to faults by restricting it to only one device.

Da der Saugkanal nunmehr aus zwei Hälften besteht, die klappbar miteinander verbunden sind, wird in vorteilhafter Weise ein Queraustritt des angesaugten Fadens möglich. Es sind zwar auch bei dieser Vorrichtung Steuermittel vorhanden, mit deren Hilfe man das Aufsetzen auf die pneumatisch miteinander zu verbindenen Öffnungen sowie das Auf- und Zuklappen, aber auch das Rückstellen des Saugglieds in der jeweils richtigen Reihenfolge bewirken kann, jedoch benötigt man diese Steuermittel aufgrund ihrer Anbringung an der Vorrichtung pro Spulmaschine nur in einem einzigen Exemplar und deshalb ist selbst bei einer aufwendigeren und damit den jeweiligen Bedürfnissen weit besser anzupassenden Steuereinrichtung der Gesamtaufwand nur ein Bruchteil dessen, was die bekannte Spulmaschine erfordert. Es kommt noch hinzu, daß man auf Kipphebel und Steuerstangen sowie ein entsprechendes Ankuppeln daran an jeder Spulstelle verzichten kann. Dies macht die Vorrichtung insgesamt sicherer und robuster. Darüber hinaus sind beim Anfahren der einzelnen Spulstellen keine so hohen Anforderungen an die Genauigkeit zu stellen.Since the suction channel now consists of two halves which are hingedly connected to one another, a transverse exit of the sucked thread is advantageously possible. There are control devices in this device as well, with the help of which one can place on the pneumatically interconnected openings and open and close, but also reset the suction element in the correct order, but these control devices are required their attachment to the device per winder only in a single copy and therefore even with a more complex control device which is therefore much better adapted to the respective requirements, the total effort is only a fraction of what the known winder requires. There is also the fact that one can do without rocker arms and control rods as well as a corresponding coupling to each winding unit. This makes the device overall safer and more robust. In addition, there are no such high demands on accuracy when starting up the individual winding units.

Der Faden od. dgl. - der Einfachheit halber wird lediglich von « Faden » gesprochen, ohne daß dies einschränkend verstanden werden darf - wird in der Spulmaschine von der Spule oder einem Cops abgenommen und zu einer neuen Spule, insbesondere einer Kreuzspule aufgewickelt. Dabei wird er auf Fehlerstellen überprüft und gereinigt. Fehlerstellen werden herausgeschnitten. Die Spulen nehmen während dieser Verarbeitung eine stehende bzw. leicht geneigte Stellung ein und der Fadenanfang befindet sich vor dem Umspulen in der Regel in dem nach oben weisenden Spulenende.The thread or the like - for the sake of simplicity only spoken of "thread", without this being understood as restrictive - is removed from the spool or a cop in the winding machine and wound up into a new spool, in particular a package. It is checked for defects and cleaned. Flaws are cut out. During this processing, the bobbins assume a standing or slightly inclined position and the thread start is usually in the upward-facing bobbin end before rewinding.

Das « Umspulen erfolgt in bekannter Weise vollautomatisch. Mit Hilfe der neuen Vorrichtung wird allerdings der Fadenanfang in eine Saugöffnung der Spulmaschine gebracht. Er wird so lange festgehalten, bis er von der Spulmaschine automatisch erfaßt und zur neu zu bewickelnden Hülse gebracht werden kann.Rewinding takes place fully automatically in a known manner. With the help of the new device, however, the thread start is brought into a suction opening of the winding machine. It is held until it can be automatically picked up by the winding machine and brought to the sleeve to be rewound.

Eine Weiterbildung der Vorrichtung ergibt sich aus Anspruch 2. Der Queraustritt für den angesaugten Fadananfang befindet sich unterhalb der Klappachse zwischen letzterer und der freien Spulenöffnung. Die Klappachse muß nicht notwendigerweise horizontal verlaufen und beim Ausführungsbeispiel ist dies auch nicht der Fall. Durch Auseinanderklappen der beiden Platten des Sauggliedkörpers kann der Faden nach unten hin austreten.A further development of the device results from claim 2. The transverse outlet for the sucked-in fadan start is below the folding axis between the latter and the free coil opening. The folding axis does not necessarily have to run horizontally, and neither is the case in the exemplary embodiment. By folding the two plates of the absorbent body apart, the thread can emerge downwards.

Eine bevorzugte Ausführungsform der Erfindung geht aus Anspruch 3 hervor. Der Zentriertrichter kann so ausgebildet sein, daß sowohl weitere Windungen als auch ein außen am Cops oder der Spule im Bereich des Zentriertrichters liegender Fadenanfang angesaugt .werden kann. Die Achse des Zentriertrichters verläuft zumindest in Arbeitsstellung etwa in Richtung der Spulen- bzw. Copsachse. Die Spulen nehmen in der Spulmaschine keine exakt definierte Lage ein, vielmehr kann das Spulenende innerhalb eines vorgegebenen Bereichs angeordnet sein. Der Zentriertrichter ist demnach so zu dimensionieren, daß er sich normalerweise über das freie Spulen- bzw. Hülsenende stülpen läßt. Letzteres gleitet beim Aufsetzen entlang der Trichterinnenwandung, so daß am Ende der Trichterzustellbewegung das freie Spulenende mit dem Trichterrohr od. dgl. fluchtet. Auch die trichterförmige Erweiterung fluchtet in der Arbeitsstellung zumindest annähernd mit der Achse des zugeordneten Saugkanalendes.A preferred embodiment of the invention is set out in claim 3. The centering funnel can be designed in such a way that both further windings and a thread start located on the outside of the cops or the bobbin in the area of the centering funnel can be sucked in. The axis of the centering funnel runs at least in the working position approximately in the direction of the coil or cop axis. The bobbins do not have an exactly defined position in the winding machine, rather the end of the bobbin can be arranged within a predetermined range. The centering funnel should therefore be dimensioned such that it normally extends over the free coil or Can end sleeve end. The latter slides along the inner wall of the funnel when it is put on, so that at the end of the funnel feed movement the free end of the coil is aligned with the funnel tube or the like. The funnel-shaped extension is also at least approximately aligned with the axis of the associated suction channel end in the working position.

Eine weitere Ausbildung der Erfindung entnimmt man Anspruch 4. Die Abdichtmanschette besteht vorzugsweise aus flexiblem Material, beispielsweise Gummi oder Kunststoff. Zweckmäßigerweise verbringt man das Verschlußglied vor dem Anlegen der abdichtenden Manschette in seine Freigabestellung.A further embodiment of the invention can be found in claim 4. The sealing sleeve is preferably made of flexible material, for example rubber or plastic. The closure member is expediently brought into its release position before the sealing sleeve is put on.

Die Ausbildung der Vorrichtung gemäß Anspruch 5 ermöglicht die gleiche Formgebung und vorzugsweise auch Dimensionierung der beiden Platten.The design of the device according to claim 5 enables the same shape and preferably also dimensioning of the two plates.

Eine weitere Ausgestaltung der Erfindung ergibt sich aus Anspruch 6. Weil das Verschlußglied eine Verschiebe- oder Drehbewegung ausführt, handelt es sich bei dem Magneten vorzugsweise um einen Hubmagneten. Das Rückführen des Verschlußglieds kann durch Federkraft erfolgen. Zweckmäßigerweise hat das Verschlußglied eine Tellerform. Es ist insbesondere daran gedacht, daß sich am freien Ende des schwenkbaren Hebels eine Rolle befindet, um die Reibung am Verschlußglied gering zu halten. Außerdem wird vorgeschlagen, daß der schwenkbare Hebel mittels einer Rückstellfeder in die Ausgangslage gebracht wird, wobei es sich beispielsweise um eine Schlingfeder auf der Schwenkachse handeln kann. Die Schwenkachse des Hebels verläuft insbesondere senkrecht zur Richtung der Plattenschwenkachse und auch senkrecht zur Plattenebene.A further embodiment of the invention results from claim 6. Because the closure member carries out a displacement or rotary movement, the magnet is preferably a lifting magnet. The closing member can be returned by spring force. Conveniently, the closure member has a plate f orm. It is particularly contemplated that there is a roller at the free end of the pivotable lever in order to keep the friction on the closure member low. It is also proposed that the pivotable lever is brought into the starting position by means of a return spring, which can be, for example, a wrap spring on the pivot axis. The pivot axis of the lever is in particular perpendicular to the direction of the plate pivot axis and also perpendicular to the plate plane.

Falls der zweite mit der Steuerung verbundene Elektromagnet lediglich das Aufklappen besorgt, erfolgt das Zuklappen entweder durch die Schwerkraft oder mittels einer Feder.If the second electromagnet connected to the control system only provides for the opening, the closing takes place either by gravity or by means of a spring.

Eine weitere Ausbildung der Erfindung ergibt sich aus Anspruch 7. Aufgrund der Kulissensteuerung kann auf eine Feder für das Zuklappen verzichtet werden. Bei der Kulissen- oder Nockensteuerung wird die Drehbewegung des Magneten nach dem Prinzip der schiefen Ebene in eine Schwenk- bzw. Klappbewegung umgesetzt. Der zugehörige bogenförmige Schlitz verläuft nicht konzentrisch zur Magnetdrehachse, sondern in verengendem Sinne, um dadurch die genannte « schiefe Ebene zu schaffen. Beim Ausführungsbeispiel sind die Verhältnisse so getroffen daß sich in der Ausgangslage, also bei geschlossenem Saugglied die beiden Zapfen und die Drehachse des Hubmagneten auf einer Ebene befinden, die vorzugsweise senkrecht zur Aufsetzrichtung verläuft.A further embodiment of the invention results from claim 7. Because of the link control, a spring for the closing can be dispensed with. In the case of link control or cam control, the rotary movement of the magnet is converted into a swiveling or folding movement according to the principle of the inclined plane. The associated arcuate slot does not run concentrically to the magnetic axis of rotation, but in a narrowing sense in order to create the so-called «inclined plane. In the exemplary embodiment, the conditions are such that in the starting position, that is to say when the suction member is closed, the two pins and the axis of rotation of the lifting magnet are on a plane which is preferably perpendicular to the direction of attachment.

Der Träger mit dem Saugglied und der Vorrichtung zur Betätigung des Verschlußglieds der Saugöffnung wird zunächst gegenüber der Spule so ausgerichtet, daß durch eine einfache, geradlinige Bewegung der Zentriertrichter auf das freie Spulenende aufgesetzt werden kann. Eine weitere Ausgestaltung der Erfindung ergibt sich aus Anspruch 9. Wenn aufgrund einer extremen Stellung der Spule in ihrer Spulmaschinenhalterung das freie Spulen- bzw. Hülsenende nicht ins Trichterinnere gelangen kann, sondern am Trichterrand des Zentriertrichters zur Anlage kommt, so bewirkt die schwenkbare Lagerung des Saugglieds über das plattenförmige Tragglied eine Verschwenkung des Letzteren. Diese Verschwen- kung kommt allein aufgrund des außermittigen Kraftangriffs, bezogen auf die Schwenkachse des Tragglieds, zustande. Man vermeidet so eine Beschädigung der Spule oder ein Festklemmen der Vorrichtung.The carrier with the suction member and the device for actuating the closure member of the suction opening is first aligned with respect to the coil so that the centering funnel can be placed on the free coil end by a simple, straight-line movement. A further embodiment of the invention results from claim 9. If, due to an extreme position of the bobbin in its winding machine holder, the free end of the bobbin or sleeve cannot reach the inside of the funnel, but comes into contact with the funnel edge of the centering funnel, the pivoting mounting of the suction member causes it a pivoting of the latter via the plate-shaped support member. This Verschwen - kung is based solely on the eccentric force application, based on the pivot axis of the support member, concluded. This prevents damage to the coil or jamming of the device.

Diese Sicherheitsvorkehrung wird ebenso wirksam, wenn die Spule im Innern des Zentriertrichters ist und die Vorrichtung in Saugstellung während dem Weiterbewegen der Spulenzuführvorrichtung blockiert sowie auch ganz besonders dann, wenn während der Saugstellung der Vorrichtung die Spulenhalterung in der Spulmaschine um mindestens eine Einheit weitergedreht wird.This safety precaution is also effective when the bobbin is inside the centering funnel and blocks the device in the suction position while the bobbin feeder is moving, and especially when the bobbin holder in the bobbin winder is rotated by at least one unit during the suction position of the device.

Eine vorteilhafte Ausbildung der Erfindung ergibt sich auch aus Anspruch 10. Die Auslenkung des plattenförmigen Tragglieds kann man mit einer akkustischen und/oder optischen Warneinrichtung kombinieren. Nach korrekter Ausrichtung der Spule und Rückführung des ausgelenkten Tragglieds mit den daran befindlichen Einrichtungen kann die automatische Fadenübergabe fortgesetzt werden. Die Führung für den Träger gewährleistet eine exakte Zustellung des Letzteren und damit auch des Saugglieds sowie der Betätigungseinrichtung für das Verschlußglied. Der Motor für das Verschieben des Trägers bewirkt einerseits ein rasches, andererseits aber ein der Situation jeweils angepasstes Zu- und Rückstellen des Trägers sowie der damit verbundenen Teile. Hierbei ist insbesondere daran gedacht, daß man einen geeigneten Antriebsmotor bzw. eine Antriebssteuerung verwendet, mittels derer zumindest ein Eil- und Schleichgang möglich ist.An advantageous embodiment of the invention also results from claim 10. The deflection of the plate-shaped support member can be combined with an acoustic and / or visual warning device. After the bobbin has been correctly aligned and the deflected support member and the devices attached to it have been returned, the automatic thread transfer can be continued. The guide for the carrier ensures an exact delivery of the latter and thus also the suction member and the actuating device for the closure member. The motor for displacing the carrier causes on the one hand a rapid, but on the other hand, the respective adjustment and resetting of the carrier and the associated parts. It is particularly contemplated that a suitable drive motor or drive control is used, by means of which at least rapid and creep speed is possible.

Eine weitere Variante der Erfindung ergibt sich aus Anspruch 11. Das Schaltelement für die entlang der Führung angeordnete Schalter muß nicht notwendigerweise direkt mit dem Träger verbunden sein. Wenn der Träger an dem insbesondere mindestens teilweise in dessen Bewegungsrichtung hintereinander angeordneten Schalter vorbeibewegt wird, so führt dies zumindest bei der Zustellbewegung des Saugglieds gleichzeitig und/oder nacheinander zu Schaltvorgängen, wobei insbesondere an die nachfolgend noch beschriebene Schaltweise gedacht ist.A further variant of the invention results from claim 11. The switching element for the switches arranged along the guide does not necessarily have to be connected directly to the carrier. If the carrier is moved past the switch, which in particular is at least partially arranged one behind the other in the direction of movement, this leads, at least during the infeed movement of the suction member, to switching operations simultaneously and / or in succession, in particular considering the switching method described below.

Ein Drehen der im Anspruch 12 erwähnten Spindel bewirkt eine Verschiebung der Mutter sowie aller mit ihr verschiebefest gekuppelten Teile. Durch Variation der Drehbewegung kann man die Verschiebebewegung verändern.Rotation of the spindle mentioned in claim 12 causes a displacement of the nut and all parts coupled to it so as to be displaceable. The displacement movement can be changed by varying the rotary movement.

Eine Weiterbildung der Erfindung geht aus Anspruch 13 hervor. Mit Hilfe der Überwachungsvorrichtung für den Faden im Saugkanal des Saugglieds kann man feststellen, ob am Ende des Verfahrensablaufs der Fadenanfang auch tatsächlich angesaugt und in die Saugöffnung der Spulmaschine gebracht wurde. Zweckmäßigerweise handelt es sich dabei um eine optische Überwachungsvorrichtung mit Lichtquelle und Detektor. Sie kann einerseits mit einer Warnanzeige, andererseits aber auch so mit der Steuerung kombiniert werden, daß eine mehrfache Wiederholung der Fadenübergabe eingeleitet wird.A further development of the invention emerges from claim 13. With the help of the monitoring device for the thread in the suction channel of the suction element, one can determine whether the thread start actually occurs at the end of the process sequence Lich sucked in and brought into the suction opening of the winder. This is expediently an optical monitoring device with a light source and detector. On the one hand, it can be combined with a warning display, but on the other hand it can also be combined with the control system so that the thread transfer is repeated several times.

Eine andere Variante der Erfindung ergibt sich aus Anspruch 14. Der in den Saugkanal mündende Druckluftkanal erzeugt eine Saugwirkung an der Spule und ersetzt oder verstärkt gegebenenfalls einen Saugluftstrom in der die Saugöffnung aufweisenden Saugleitung der Spulmaschine.Another variant of the invention results from claim 14. The compressed air channel opening into the suction channel creates a suction effect on the coil and, if necessary, replaces or amplifies a suction air flow in the suction line of the winding machine having the suction opening.

Eine weitere Ausbildung der Erfindung geht aus Anspruch 15 hervor. Sie ermöglicht es, die Vorrichtung von einer Arbeitsstation der Spulmaschine zur nächsten weiterzutransportieren. Dies geschieht insbesondere mit Hilfe eines Antriebsmotors und einer Steuerung, welche gewährleistet, daß das Weiterfahren zur nächsten Arbeitsstation der Spulmaschine erst dann erfolgt, wenn an der momentan angefahrenen Station der Fadenanfang auch tatsächlich übergeben ist.A further embodiment of the invention emerges from claim 15. It enables the device to be transported from one work station of the winding machine to the next. This is done in particular with the aid of a drive motor and a control which ensures that the next work station of the winding machine is only moved on when the thread start has actually been transferred to the station currently being approached.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert. Hierbei stellen dar:

  • Fig. 1 eine Seitenansicht der Vorrichtung, teilweise geschnitten,
  • Fig. 2 eine Teilansicht der Fig. 1, in Pfeilrichtung A gesehen.
  • Fig. 3 einen Teilschnitt der Fig. 1 in Pfeilrichtung B-B.
The invention is explained below with reference to the drawing. Here represent:
  • 1 is a side view of the device, partially in section,
  • Fig. 2 is a partial view of Fig. 1, seen in the direction of arrow A.
  • Fig. 3 is a partial section of Fig. 1 in the direction of arrow BB.

Fig. 1 zeigt die Vorrichtung in ihrer Gebrauchslage, d. h. der Großteil ihrer Elemente nimmt dabei eine Schräglage ein. Sie dient zur Übergabe des Fadenanfangs einer Spule 1, eines sogenann- . ten Cops, von der Spulenhülse 2 an eine Saugöffnung 3 einer Spulmaschine 4. Von letzterer ist allerdings nur der Teil eines Spulenbehälters 5 zu sehen, der rotationsymmetrisch aufgebaut und um eine Achse 6 drehbar ist. Er besitzt mehrere Aufnahmen 7 für jeweils eine Spule 1, die gleichmäßig am Umfang verteilt sind und schrittweise so weitergeschaltet werden, daß jeweils eine Spule 1 die aus der Zeichnung ersichtliche Zuordnung zur Übergabevorrichtung erhält. Demnach nimmt also die Spule 1 bzw. dereren Längsachse 8 in der Faden-Übergabestellung zur Vertikalen 9 eine Schräglage unter einem Winkel 10 ein.Fig. 1 shows the device in its position of use, i. H. the majority of their elements assume an inclined position. It serves to transfer the thread start of a bobbin 1, a so-called. ten cops, from the bobbin tube 2 to a suction opening 3 of a bobbin winder 4. Of the latter, however, only the part of a bobbin case 5 can be seen that is rotationally symmetrical and rotatable about an axis 6. It has a plurality of receptacles 7 for one coil 1 each, which are evenly distributed over the circumference and are stepped forward in such a way that in each case one coil 1 receives the assignment to the transfer device shown in the drawing. Accordingly, the bobbin 1 or its longitudinal axis 8 assumes an oblique position at an angle 10 in the thread transfer position to the vertical 9.

Vor dem Einsetzen der Spule 1 in den Spulenbehälter 5 ist der Fadenanfang 11 in eine der Spulenöffnungen eingesteckt, die nach dem Einsetzen in den Spulenbehälter 5 letzteren überragt und somit die freie Spulenöffnung 12 bildet. Jede Spulmaschine besitzt eine Vielzahl solcher Spulenbehälter in insbesondere gleichem seitlichen Abstand. Der Faden wird von der Spulenhülse 2 in der Spulmaschine abgewickelt, geprüft bzw. « veredelt », indem man Fehlstellen entfernt, und anschließend erneut zu einer Spule, vorzugsweise Kreuzspule, aufgewickelt. Hierzu ist es erforderlich, daß der Fadenanfang 11 in die Saugöffnung 3 verbracht und dort so lange festgehalten wird, bis das Fadenstück zwischen Spule 1 und Saugöffnung 3 von einem entsprechenden Organ erfaßt und der Spulmaschine zur weiteren Bearbeitung zugeführt wird.Before the bobbin 1 is inserted into the bobbin case 5, the beginning of the thread 11 is inserted into one of the bobbin openings, which projects beyond the latter into the bobbin case 5 and thus forms the free bobbin opening 12. Each winding machine has a large number of such bobbin containers, in particular at the same lateral distance. The thread is unwound from the bobbin tube 2 in the winding machine, checked or “refined” by removing imperfections, and then wound up again to form a bobbin, preferably a cheese. For this purpose, it is necessary that the thread start 11 is placed in the suction opening 3 and held there until the thread piece between the bobbin 1 and the suction opening 3 is gripped by a corresponding organ and fed to the winding machine for further processing.

Gemäß der Erfindung wird der Fadenanfang 11 automatisch von der Spule 1 an die Saugöffnung 3 übergeben. Zu diesem Zwecke wird auf die freie Spulenöffnung ein Saugglied 13 mit einem Saugkanal 14 aufgesetzt, der beim Ausführungsbeispiel bogenförmig verläuft. Dadurch erfolgt eine pneumatische Verbindung zwischen der Spule 1 bzw. der freien Spulenöffnung 12 und der Saugöffnung 3 der Spulmaschine. Mit Hilfe eines im Saugkanal 14 herrschenden Sogs wird der Fadenanfang 11 aus dem Hülseninneren herausgesogen und unter Abwicklung eines Fadenstücks von der Spule 1 durch den Saugkanal 14 hindurch in den Luftkanal 15 der Spulmaschine transportiert, dessen freies Ende die erwähnte Saugöffnung 3 bildet. In diesem Falle nützt man die an der Spulmaschine üblicherweise vorhandene Unterdruckeinrichtung aus. Statt dessen ist es aber ohne weiteres möglich, in den Saugkanal 14 einen Druckluftkanal 16 münden zu lassen, wie in Fig. mit strichpunktierten Linien beispielsweise angedeutet ist. Die durch letzteren zugeführte Druckluft hat ebenfalls eine Saugwirkung im Kanal 14 zur Folge, so daß man auch mit Hilfe von Druckluft den Fadenanfang ansaugen und zum Kanal 15 transportieren kann. Des weiteren kann man an geeigneter Stelle eine Überwachungsvorrichtung anbringen, mit deren Hilfe man die erfolgte Übergabe des Fadenanfangs von der Spule 1 an die Spulmaschine 4 überprüfen bzw. feststellen kann. Zweckmmäßigerweise handelt es sich um eine optische Überwachungsvorrichtung im Bereich des Saugkanals 14.According to the invention, the beginning of the thread 11 is automatically transferred from the bobbin 1 to the suction opening 3. For this purpose, a suction member 13 with a suction channel 14 is placed on the free coil opening, which runs in an arc in the embodiment. This results in a pneumatic connection between the coil 1 or the free coil opening 12 and the suction opening 3 of the winding machine. With the help of a suction prevailing in the suction channel 14, the thread beginning 11 is sucked out of the inside of the sleeve and, while unwinding a piece of thread from the bobbin 1, is transported through the suction channel 14 into the air duct 15 of the winding machine, the free end of which forms the suction opening 3 mentioned. In this case, use is made of the vacuum device usually present on the winding machine. Instead, however, it is readily possible to have a compressed air channel 16 open into the suction channel 14, as is indicated, for example, by dash-dotted lines in FIG. The compressed air supplied by the latter also results in a suction effect in channel 14, so that the thread start can also be sucked in with the aid of compressed air and transported to channel 15. Furthermore, a monitoring device can be fitted at a suitable point, with the aid of which the transfer of the thread start from the bobbin 1 to the bobbin winder 4 can be checked or ascertained. It is expedient to use an optical monitoring device in the area of the suction channel 14.

Die Spule 1 nimmt im Spulenbehälter 5 nicht unbedingt die in Fig. 1 bezeichnete Lage ein, vielmehr ist auch eine gewisse Schrägstellung hierzu, also ein Verschwenken des freien Spulenendes in die Bildebene hinein oder aus dieser heraus oder quer hierzu möglich. Um trotzdem das Saugglied 13 sicher auf das freie Hülsenende aufsetzten zu können, befindet sich an dem der freien Spulenöffnung 12 zugekehrten Ende des Saugkanals 14 ein Zentriertrichter 17. Auch am anderen, der Saugöffnung 3 zugekehrten Ende des Saugkanals 14 ist eine trichterförmige Erweiterung 18 vorhanden. An diese schließt sich eine Abdichtmanschette 19 aus weichelastischem Material wie Gummi, Kunststoff od. dgl. an. Sie liegt während der Fadenübergabe jedoch nicht unmittelbar auf dem oberen Ende des Luftkanals 15 auf, sondern auf dem dazwischen befindlichen, in der Art eines Tellers mit nach unten abgewinkeltem Rand 20 ausgebildeten Verschlußglied 21 für die Saugöffnung 3. Dieses Verschlußglied ist exzentrisch drehbar oder verschiebbar an der Oberseite des Spulenbehälters 5 gelagert. Es besitzt einen Durchbruch 22, der sich in der Ausgangsstellung, also vor dem Aufsetzen des Zentriertrichters 17 auf das freie Spulenende seitlich der Saugöffnung 3 befindet, so daß letztere durch das Verschlußglied 21 abgedeckt ist. Erst wenn man in der nachstehend beschriebenen Weise das Verschlußglied verschiebt bzw. verschwenkt, wird die pneumatische Verbindung zwischen dem Luftkanal 15 und dem Saugkanal 14 über den Durchbruch 22 hergestellt. Die Abdichtmanschette 19 wird erst nach dem Freigeben der Saugöffnung 3 angedrückt.The coil 1 in the coil container 5 does not necessarily assume the position shown in FIG. 1, rather a certain inclination to it, that is to say pivoting of the free coil end into or out of the image plane or transversely thereto is possible. In order nevertheless to be able to place the suction member 13 securely on the free sleeve end, there is a centering funnel 17 at the end of the suction channel 14 facing the free coil opening 12. A funnel-shaped extension 18 is also present at the other end of the suction channel 14 facing the suction opening 3. This is followed by a sealing collar 19 made of flexible material such as rubber, plastic or the like. During the thread transfer, however, it does not rest directly on the upper end of the air duct 15, but on the intervening closure member 21 for the suction opening 3, which is designed in the manner of a plate with an angled-down edge 20. This closure member can be rotated or displaced eccentrically the top of the bobbin 5 stored. It has an opening 22 which is in the starting position, that is to say before the centering funnel 17 is placed on the free coil end, at the side of the suction opening 3, so that the latter is covered by the closure member 21. Only when you move or lock the closure member in the manner described below pivots, the pneumatic connection between the air duct 15 and the suction duct 14 is established via the opening 22. The sealing collar 19 is pressed on only after the suction opening 3 has been released.

Wenn der Fadenanfang in die Saugöffnung 3 übergeben ist, muß man das Saugglied 13 abnehmen. Dies geschieht durch Anheben in Pfeilrichtung 23. Um ein Mitnehmen des Fadenanfangs bei dieser Anhebewegung zu vermeiden, wird zunächst eine Queraustrittsöffnung für den Faden freigegeben. Der Faden-Queraustritt wird dadurch möglich, daß das Saugglied aus zwei um eine Achse 24 klappbar miteinander verbundenen Teilen besteht, die man je nach Bedarf zusammen-oder auseinanderklappen kann. Während des Saugens sind die beiden Teile, insbesondere Hälften, selbstverständlich zusammengeklappt, - wie in Fig. 2 mit festen Linien dargestellt ist - während sie gemäß der gestrichelten Darstellung der Fig. 2 insbesondere beim Hochheben der Vorrichtung zur Bildung des Queraustritts 25 auseinandergeklappt werden.When the beginning of the thread is passed into the suction opening 3, the suction member 13 must be removed. This is done by lifting in the direction of arrow 23. In order to avoid entrainment of the thread start during this lifting movement, a transverse exit opening for the thread is first released. The transverse thread exit is made possible in that the suction member consists of two parts which can be folded together about an axis 24 and which can be folded or unfolded as required. During suction, the two parts, in particular halves, are of course collapsed, as is shown in FIG. 2 with solid lines, while, according to the dashed illustration in FIG. 2, they are opened apart, in particular when the device for forming the transverse outlet 25 is raised.

Bei den beiden klappbar miteinander verbundenen Sauggliedteilen 26 und 27 handelt es sich im wesentlichen um plattenförmige Elemente. Sie sind so ausgebildet, daß sich in jedem ein halber Saugkanal 14 befindet. Demzufolge trägt auch jedes Sauggliedteil einen halben Zentriertrichter und eine Hälfte des Trichters 18 mit einer Manschettenhälfte. Aus der Zeichnung ersieht man ferner, daß sich die Klappachse 24 an dem in Aufsetzrichtung 28 rückwärtigen Ende des Sauggliedes 13 befindet. Die beiden klappbar miteinander verbundenen Platten bilden den Sauggliedkörper 29.The two hingedly connected suction member parts 26 and 27 are essentially plate-shaped elements. They are designed so that there is a half suction channel 14 in each. As a result, each suction member part also carries half a centering funnel and half of the funnel 18 with a sleeve half. From the drawing it can also be seen that the folding axis 24 is located at the rear end of the suction member 13 in the mounting direction 28. The two plates which are hingedly connected to one another form the suction member body 29.

Das Verschlußglied 21 ist mittels eines ersten steuerbaren Elektromagneten 30 verstellbar. Sein Anker ist über einen Bolzen 31 mit einem im Sinne des Doppelpfeils 33 schwenkbaren Hebel 32 gekuppelt. Dessen Drehachse 34 liegt gemäß Fig. 1 über dem Hubmagneten 30. Es handelt sich um einen einarmigen Hebel. An seinem freien Ende trägt er eine Rolle 72. In Fig. 1 ist mit festen Linien die Arbeitsstellung des Hebels 32 und mit gestrichelten Linien seine Ausgangslage dargestellt, in welcher das Verschlußglied 21 die Saugöffnung 3 noch verschlossen hält. Setzt man den Hubmagneten 30 unter Strom, so zieht der Anker den Hebel 32 von der gestrichtelten Steilung in die mit festen Linien gezeichnete, wodurch das Verschlußglied 21 in seine mit gestrichelten Linien dargestellte Verschiebelage oder Freigabestellung für die Saugöffnung 3 verschwenkt oder verschoben wird. Das Rückstellen der ausgelenkten Teile kann durch Federkraft erfolgen. Eine Rückstellfeder für den Hebel 32 befindet sich beim oder im Hubmagnet 30.The closure member 21 is adjustable by means of a first controllable electromagnet 30. Its anchor is coupled via a bolt 31 to a lever 32 which can be pivoted in the direction of the double arrow 33. 1, the axis of rotation 34 lies above the lifting magnet 30. It is a one-armed lever. At its free end it carries a roller 72. In Fig. 1, the working position of the lever 32 is shown with solid lines and its starting position is shown with broken lines, in which the closure member 21 still keeps the suction opening 3 closed. If the solenoid 30 is energized, the armature pulls the lever 32 from the broken line into the one drawn with solid lines, as a result of which the closure member 21 is pivoted or shifted into its shifted position or release position for the suction opening 3, shown with broken lines. The deflected parts can be reset by spring force. A return spring for the lever 32 is located at or in the solenoid 30.

Auch das Aufspreizen der beiden Platten bzw. Teile 26 und 27 des Sauggliedkörper 29 erfolgt mit Hilfe eines Magneten, nämlich eines zweiten steuerbaren Elektromagneten 35. Dabei handelt es sich vorzugsweise um einen Drehmagneten, der die beiden Platten bzw. Sauggliedteile 26 und 27 über eine, vorzugsweise doppelte Kulissensteuerung 36 auf- und zuklappt.The two plates or parts 26 and 27 of the suction member body 29 are also spread apart with the aid of a magnet, namely a second controllable electromagnet 35. This is preferably a rotary magnet which connects the two plates or suction member parts 26 and 27 via a preferably double link control 36 opens and closes.

Zu diesem Zwecke trägt die Drehachse 47 des zweiten Magneten 35 einen doppelarmigen Hebel 38, an dessen Enden sich je ein Zapfen 39 bzw. 40 der Kulissensteuerung befindet. Jeder greift in einen bogenförmigen Schlitz 41 bzw. 42 je eines Steueransatzes 43 bzw. 44 der zugeordneten Platte bzw. des zugeordneten Sauggliedteils 26, 27 ein. Dreht sich der Anker des Magneten, so hat dies eine Schwenkbewegung des doppelarmigen Hebels 38 mit den Zapfen 39 und 40 zur Folge. Aufgrund des Verlaufs der bogenförmigen Schlitze drücken die Zapfen 39 und 40 die Steueransätze 43 bzw. 44 und damit die Sauggliedteile 26 bzw. 27 im Sinne des Pfeils 45 bzw. 46 nach außen. Durch den keilförmigen Spaltraum zwischen den beiden Sauggliedteilen 26 und 27 wird der erwähnte Queraustritt 25 für den übergebenen Fadenanfang geschaffen. Bei geschlossenem Saugkanal 14 liegen die Drehachse des zweiten Magneten 35 sowie die Zapfen 39 und 40 auf einer gemeinsamen Geraden bzw. Ebene. Außerdem erkennt man aus Fig. 2, daß die Drehachse 47 des zweiten Magneten 35 parallel zur Klappachse 24 der Platten bzw. Sauggliedteile 26, 27 angeordnet ist.For this purpose, the axis of rotation 47 of the second magnet 35 carries a double-armed lever 38, at the ends of which there is a pin 39 or 40 of the link control. Each engages in an arcuate slot 41 or 42 each of a control projection 43 or 44 of the associated plate or the associated suction member part 26, 27. If the armature of the magnet rotates, this results in a pivoting movement of the double-armed lever 38 with the pins 39 and 40. Due to the course of the arcuate slots, the pins 39 and 40 press the control lugs 43 and 44 and thus the suction member parts 26 and 27 in the direction of arrow 45 and 46 to the outside. Through the wedge-shaped gap between the two suction member parts 26 and 27, the above-mentioned transverse exit 25 is created for the transferred thread start. When the suction channel 14 is closed, the axis of rotation of the second magnet 35 and the pins 39 and 40 lie on a common straight line or plane. 2 that the axis of rotation 47 of the second magnet 35 is arranged parallel to the folding axis 24 of the plates or suction member parts 26, 27.

Das Saugglied 13 und die Vorrichtung zur Betätigung des Verschlußglieds 21 der Saugöffnung 3, im wesentlichen also der Hebel 32 und der erste Magnet 30 sind an einem etwa in Längsrichtung der Spule 1 zu- und rückstellbaren Träger 48 gehalten. Zwischen dem Träger und dem Saugglied 13 ist jedoch noch ein plattenförmiges Tragglied 49 geschaltet. Es ist um eine Achse 50 im Sinne des Doppelpfeils 51 schwenkbar am Träger 48 gelagert. Zu diesem Zwecke befinden sich am Träger 48 zwei das Tragglied 49 zwischen sich aufnehmende Lagerlaschen 52 und 53. Die erwähnte Klappachse 24 für das Saugglied 13 verläuft parallel zur Achse 50 des Tragglieds 49, wie man insbesondere Fig. 1 entnehmen kann. Aus beiden Figuren ist ersichtlich, daß das Tragglied 49 in seiner Normalstellung mit Hilfe zweier zwischen die Lagerlaschen und die zugeordneten stirnseitigen Plattenenden geschalteten Zentriereinrichtungen 54 und 55 gehalten ist, die in der Art von Schneppern ausgebildet sein können, und ein Verschwenken des Tragglieds 49 gegenüber dem Träger 48 gestatten, wenn eine die Schnepperkraft übertreffende Verschwenkkraft am Tragglied 49 angreift. Dies kann dann der Fall sein, wenn die Stellung der Spule 1 von der dargestellten in extremer Weise abweicht, so daß der freie Rand des Zentriertrichters 17 auf dem freien Hülsenende auftrifft, oder wenn die Spule im Innern des Zentriertrichters ist und die Vorrichtung in abgesenkter Stellung während der Weiterbewegung der Spulenzuführvorrichtung blockiert, oder wenn während der abgesenkten Stellung der Vorrichtung die Spulenhalterung in der Spulmaschine weiterbewegt wird. Dadurch entsteht ein Drehmoment, welches über die Klappachse 24 auf das Tragglied 49 übertragen wird, und so die Verschwenkung des letzteren bewirkt. Ein mit dem Tragglied 49 verbundenes Schaltglied 56 macht diese Auslenkbewegung mit und betätigt dadurch einen ortsfest am Träger 48 gehaltenen Schalter 57. Diesen Schaltvorgang kann man in geeigneter Weise ausnutzen, beispielsweise zum Abschalten einer Vorrichtung für die automatische Zuführung der Spulen 1 in den Spulenbehälter 5.The suction member 13 and the device for actuating the closure member 21 of the suction opening 3, that is to say essentially the lever 32 and the first magnet 30, are held on a support 48 which can be moved and reset approximately in the longitudinal direction of the coil 1. However, a plate-shaped support member 49 is still connected between the support and the suction member 13. It is pivotably mounted on the carrier 48 about an axis 50 in the sense of the double arrow 51. For this purpose, the support member 49 has two mounting brackets 52 and 53 on the support 48. The mentioned folding axis 24 for the suction member 13 runs parallel to the axis 50 of the support member 49, as can be seen in particular in FIG. 1. From both figures it can be seen that the support member 49 is held in its normal position with the aid of two centering devices 54 and 55 connected between the mounting brackets and the associated end plate ends, which can be designed in the manner of snipers, and a pivoting of the support member 49 relative to the Allow carrier 48 when a pivoting force exceeding the claw force acts on the support member 49. This can be the case if the position of the coil 1 deviates from the illustrated in an extreme manner so that the free edge of the centering funnel 17 hits the free end of the sleeve, or if the coil is inside the centering funnel and the device is in the lowered position blocked during the further movement of the bobbin feed device, or if the bobbin holder is moved further in the bobbin winder while the device is in the lowered position. This creates a torque which is transmitted to the support member 49 via the folding axis 24, and thus causes the latter to pivot. A circuit connected to the support member 49 member 56 joins this deflection movement and thereby actuates a switch 57 held stationary on the carrier 48. This switching process can be used in a suitable manner, for example for switching off a device for automatically feeding the coils 1 into the coil container 5.

Der Träger 48 ist im Sinne des Doppelpfeils 58 verschiebb- und festsetzbar an einer Führung 59 der Vorrichtung gelagert. Diese Führung erstreckt sich etwa parallel zu der Spulen-Längsachse 8 bzw. Drehachse 6 des Spulenbehälters 5. Dadurch erreicht man ein zentrisches Zuführen des Zentriertrichters 17 gegen das schräg nach oben weisende Ende der Spulenhülse 2. Der Träger 48 ist also geneigt zur Vertikalen auf- und abverschiebbar und zwar mit Hilfe eines Elektromotors 60. Dabei handelt es sich um einen permanent erregten Motor mit einer Vier-Quadranten-Antriebssteuerung. Seine Drehbewegung wird über einen Antrieb 61, z. B. Zahnriemenantrieb, auf eine Spindel 62 übertragen, die eine drehbar aber unverschiebbar am Träger 48 gehaltene Mutter durchsetzt. Eine Drehung in der einen Richtung bewirkt ein Anheben des Trägers 48 und aller verschiebefest daran gehaltenen Teile im Sinne des Pfeils 23, während eine gegenläufige Drehbewegung das Absenken in Pfeilrichtung 28 zur Folge hat.The carrier 48 is mounted on a guide 59 of the device so that it can be moved and fixed in the direction of the double arrow 58. This guide extends approximately parallel to the longitudinal axis 8 of the coil or axis of rotation 6 of the coil container 5. This results in a central feeding of the centering funnel 17 against the obliquely upward-pointing end of the coil sleeve 2. The carrier 48 is thus inclined to the vertical. and displaceable with the help of an electric motor 60. This is a permanently excited motor with a four-quadrant drive control. Its rotational movement is via a drive 61, for. B. toothed belt drive, transferred to a spindle 62 which passes through a rotatably but non-displaceably held on the carrier 48 nut. A rotation in one direction causes the carrier 48 and all parts held thereon to be displaceably lifted in the direction of the arrow 23, while an opposite rotational movement results in the lowering in the direction of the arrow 28.

Aus Fig. 1 ersieht man, daß entlang der Führung 59 verschiedene Schalter, insbesondere berührungslos arbeitende elektrische oder elektronische Schalter, angebracht sind. Sie tragen die Bezugszahlen 63, 64, 65, 66 und 67 und sind an einer Führungsleiste 70 stufenlos einstellbar. Sie arbeiten mit einem mit dem Träger 48 mitbewegten Schaltelement 71 zusammen.From Fig. 1 it can be seen that 59 different switches, in particular contactless electrical or electronic switches, are attached along the guide. They bear the reference numbers 63, 64, 65, 66 and 67 and are infinitely adjustable on a guide bar 70. They work together with a switching element 71 which is moved with the carrier 48.

Ausgehend von einer angehobenen Endstellung des Trägers 48 und damit auch des Saugglieds 13 wird durch einen entsprechenden Befehl den elektrische Antriebsmotor 60 für die Zustellung des Saugglieds 13 in Gang gesetzt. Dabei ist das Saugglied 13 noch geschlossen, d. h. der Drehmagnet 35 ist stromlos und seine beiden Teile 26 und 27 sind zusammengeklappt. Mit dem Verlassen des Schalters 63, des Schaltelements 71 wird der Drehmagnet 35 eingeschaltet und somit das Saugglied 13 geöffnet, die Teile 26 und 27 aufgeklappt.Starting from a raised end position of the carrier 48 and thus also the suction member 13, the electric drive motor 60 is set in motion for the delivery of the suction member 13 by a corresponding command. The suction member 13 is still closed, i.e. H. The rotary magnet 35 is de-energized and its two parts 26 and 27 are folded together. When the switch 63, the switching element 71 is left, the rotary magnet 35 is switched on and thus the suction member 13 is opened and the parts 26 and 27 are opened.

Wenn das mit dem Träger 48 mitbewegte Schaltglied 71 den Schalter 64 erreicht hat, wird der Stromkreis des zweiten Magneten 35 wieder unterbrochen, was zum Zusammenklappen der beiden Hälften des Saugglieds in die Arbeitsstellung führt und so das Zentrieren des Cops ermöglicht. Der Schalter 67 bewirkt, daß von dem zuvor wirksamen Eilgang auf einen Schleichgang, also eine verlangsamte Weiterbewegung umgeschaltet wird. Die Betätigung des Schalters 65 bewirkt das Schließen des Stromkreises für den Hubmagneten 30 und damit das Hereinschwenken des Hebels 32 bzw. Freigeben der Saugöffnung 3 durch das Verschlußglied 21. Mit dem Schalter 66 wird schließlich die Zustellbewegung in Pfeilrichtung 28 beendet.When the switching element 71 moved with the carrier 48 has reached the switch 64, the circuit of the second magnet 35 is interrupted again, which leads to the folding of the two halves of the suction element into the working position and thus enables the cop to be centered. The switch 67 has the effect that the previously active rapid traverse is switched to a creep speed, that is to say a slowed-down further movement. The actuation of the switch 65 causes the circuit for the solenoid 30 to be closed and thus the lever 32 to be swiveled in or the suction opening 3 to be released by the closure member 21. The feed movement in the direction of the arrow 28 is finally ended with the switch 66.

Auf ein entsprechendes Kommando hin wird der Träger 48 im Eilgang wieder angehoben und gleichzeitig das Saugglied 13 auseinandergeklappt sowie das Verschlußglied 21 in seine Schließstellung überführt. Bei erreichen des Schalters 63 wird schließlich das Stillsetzen des Motors 60 und damit auch des Trägers 48 bewirkt.Upon a corresponding command, the carrier 48 is raised again in rapid traverse and at the same time the suction member 13 is unfolded and the closure member 21 is moved into its closed position. When the switch 63 is reached, the motor 60 and thus also the carrier 48 are finally stopped.

Die Vorrichtung ist mit Rollen 68, Gleitschuhen od. ähnlichen Elementen ausgestattet, mit deren Hilfe sie entlang einer Führung, insbesondere Führungsschiene 69 der Spulmaschine senkrecht zur Bildebene in Fig. 1 verschoben werden kann.The device is equipped with rollers 68, slide shoes or similar elements, with the aid of which it can be displaced along a guide, in particular guide rail 69, of the winding machine perpendicular to the image plane in FIG. 1.
