- Such winding units 2 each have, for example, an electronic thread cleaner 14, a thread splicing device 17 and a thread tensioner 18.
- the yarn splicing device 17 after a spool interruption, for example after a thread break or a controlled thread cleaner cut, the upper thread originating from the cross-wound bobbin 7 and the bobbin thread connected to the spinning cop 4 are again pneumatically connected.
- the upper thread is inserted by means of a suction nozzle 15 in the Fadensleiiß Rhein 17, while the lower thread is prepared by a gripper tube 16.
- the yarn ends 6 of the stored in the round magazine 3 fresh spinning cops 4 are each positioned in a suction air duct 13, which is closed by a cover member 12 consisting of a manual operating cover 20 and an automatic cover 19.
- the yarn ends 6 of the round magazine 3 held ready for rewinding spinning cops 4 are clamped between the manual operating cover 20 and the automatic cover 19 and thus mechanically fixed.
- each winding unit 2 has a so-called auxiliary gripper 24 which, after a spinning head change, that is, when a spinning cop positioned in the unwinding position II is unwound and replaced by a fresh spinning cop from the round magazine, ensures that the thread strand which extends between the spinning cop 4 positioned on a Kopsaufsteckdorn 25 and the cover member 12, is transferred to the gripper tube 16 of the winding unit 2.
- the Figure 3 shows the structure of the cover element 12 according to the invention and the operation of the manual operating cover 20 and the automatic cover 19 in detail.

Description
Die Erfindung betrifft ein Rundmagazin für eine Spulstelle eines Kreuzspulautomaten gemäß dem Oberbegriff des Anspruches 1.The invention relates to a round magazine for a winding unit of a cheese winder according to the preamble of claim 1.
Rundmagazine zur Versorgung der Spulstellen von Kreuzspulautomaten mit frischen Spinnkopsen sind bekannt und in der Patentliteratur, beispielsweise in der
Derartige Rundmagazine sind außerdem Gegenstand des Handbuches Schlafhorst Winding Systems "Autoconer 338", Seite 4/45 sowie Seite 4/46.Round magazines for supplying the winding units of automatic cheese winder with fresh spinning heads are known and in the patent literature, for example in the
Such round magazines are also the subject of the manual Schlafhorst Winding Systems "Autoconer 338",
Wie bekannt, bestehen derartige Rundmagazine im Wesentlichen aus einem drehbar gelagerten Magazin mit Aufnahmetaschen für einzelne Spinnkopse, einer unteren Auflageplatte mit einer Spinnkops-Ausschleusöffnung sowie einem im Bereich der Mittellängsachse des Rundmagazins angeordneten Saugluftkanal zum Fixieren der Fadenenden der im Rundmagazin bevorrateten Spinnkopse.
Der Saugluftkanal ist durch ein Deckelelement verschließbar, das um eine Schwenkachse, die parallel zum Saugluftkanal verläuft, begrenzt drehbar gelagert und sowohl manuell als auch maschinell betätigbar ist.
Das Deckelelement kann beispielsweise beim Befüllen des Rundmagazins mit frischen Spinnkopsen zum Einlegen der Fadenenden der Spinnkopse in den Saugluftkanal von Hand geschwenkt werden oder im Zuge der Überführung der Spinnkopse aus dem Rundmagazin in ihre Abspulstellung an der Spulstelle sowie zum anschließenden Entsorgen der abgelängten Fadenenden, maschinell angesteuert werden.As known, such circular magazines essentially consist of a rotatably mounted magazine with receiving pockets for individual spinning cops, a lower platen with a Spinnkops Ausschleusöffnung and arranged in the region of the central longitudinal axis of the round magazine suction air channel for fixing the yarn ends of stockpiled in round magazine spinning cops.
The suction air channel can be closed by a cover element, which is rotatably mounted to a limited extent about a pivot axis which runs parallel to the suction air duct and can be actuated manually as well as mechanically.
The lid member, for example, when filling the round magazine with fresh spinning cops for inserting the thread ends of the spinning cops are pivoted by hand in the suction duct or in the course of the transfer of the spinning cops from the round magazine in its Abspulstellung at the winding unit and the subsequent Disposal of the cut ends of the thread can be controlled by machine.
Wenngleich sich solche Rundmagazine bei Kreuzspulautomaten in der Praxis vielfach bewährt haben und seit langer Zeit erfolgreich im Einsatz sind, sind auch derartige Rundmagazine noch verbesserungsfähig.
Insbesondere im Bereich des Deckelelementes, das, wie vorstehend erläutert, einen im Bereich der Mittellängsachse des Rundmagazins angeordneten Saugluftkanal temporär verschließt und dabei die Fadenenden der im Rundmagazin bevorrateten Spinnkopse mechanisch fixiert, können gelegentlich Schwierigkeiten auftreten.
Bei Spinnkopsen, die stark kringelndes Fadenmaterial aufweisen, kann es beispielsweise geschehen, dass sich die Fadenenden im Rundmagazin benachbart angeordneter Spinnkopse miteinander verzwirnen.
Wenn ein solcher Spinnkops, dessen Fadenende mit dem Fadenende eines benachbarten Spinnkopses verzwirnt ist, dann aus dem Rundmagazin in seine Abspulstellung an der Spulstelle überführt wird, besteht die Gefahr, dass es zu Komplikationen kommt, das heißt, dass die Saugluftströmung des zu diesem Zeitpunkt teilweise geöffneten Saugluftkanals nicht ausreicht, um das Fadenende wieder so straff zu ziehen, dass es nachfolgend von einem so genannten Hilfsgreifer sicher an das Greiferrohr der Spulstelle übergeben werden kann, mit der Folge, dass die Fadenübergabe fehlschlägt.Although such circular magazines have proven themselves many times in automatic winder and have been used successfully for a long time, even such round magazines are still capable of improvement.
In particular, in the region of the cover element, which, as explained above, temporarily closes a suction air duct arranged in the region of the central longitudinal axis of the round magazine and mechanically fixes the yarn ends of the spinning cops stored in the round magazine, difficulties may occasionally arise.
In the case of spinning cops, which have highly curling thread material, it may happen, for example, that the thread ends in the round magazine adjoin adjacent arranged spinning cops.
If such a spinning cop, the yarn end is twisted with the yarn end of an adjacent Spinnkopses, then transferred from the round magazine in its unwinding at the winding unit, there is a risk that it comes to complications, that is, the Saugluftströmung the at this time partially open suction air duct is not sufficient to pull the thread end so tight that it can be subsequently passed by a so-called auxiliary gripper safely to the hook tube of the winding unit, with the result that the thread transfer fails.
Da jede fehlgeschlagene Fadenübergabe einen manuellen Eingriff seitens des Bedienpersonals erfordert, das Bedienpersonal jedoch mit der Befüllung der Rundmagazine mehrerer Kreuzspulautomaten bereits voll ausgelastet ist, wirkt sich eine fehlerhafte Fadenübergabe in der Regel sofort negativ auf den Nutzeffekt des Kreuzspulautomaten aus und sollte daher möglichst vermieden werden.Since each failed thread transfer requires manual intervention on the part of the operating personnel, but the operator is already fully utilized with the filling of the round magazines multiple spoolers, a faulty thread transfer usually has a negative effect on the net effect of Spinning machines and should therefore be avoided as far as possible.
Ausgehend von Rundmagazinen der vorstehend beschriebenen Gattung liegt der Erfindung die Aufgabe zugrunde, die bekannten Rundmagazine dahingehend zu verbessern, dass, insbesondere im Zusammenhang mit der Überführung von Spinnkopsen aus dem Rundmagazin in die Abspulstellung der Spulstelle, Schwierigkeiten bei der Fadenübergabe zuverlässig vermieden werden.Based on round magazines of the type described above, the invention has the object to improve the known round magazines to the effect that, especially in connection with the transfer of spinning heads from the round magazine in the unwinding of the winding unit, difficulties in the yarn transfer are reliably avoided.
Diese Aufgabe wird erfindungsgemäß durch ein Rundmagazin gelöst, das die im Kennzeichen des Anspruchs 1 beschriebenen Merkmale aufweist.This object is achieved by a round magazine having the features described in the characterizing part of claim 1.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Ausbildung eines Rundmagazins mit einem Handbetätigungsdeckel sowie einem Automatikdeckel, die jeweils separat betätigbar sind und bei der in der Oberseite des Handbetätigungsdeckels eine nutförmige Aussparung angeordnet ist, die einen an den Saugluftkanal des Rundmagazins angeschlossenen Luft- und Fadenführungskanal bildet, der durch den Automatikdeckel verschließbar ist, führt zu einer aerodynamisch vorteilhaften Konstruktion.
Das heißt, die beim Öffnen des Automatikdeckels in der nutförmigen Aussparung des Handbetätigungsdeckels herrschende Saugluftströmung sorgt nicht nur dafür, dass das Fadenende des in der Übergabestellung des Rundmagazins positionierten Spinnkopses in die nutförmige Aussparung gleitet, sondern gewährleistet während der Überführung eines Spinnkopses vom Rundmagazin in die Abspulstellung der Spulstelle auch eine zuverlässige Separierung des Fadenendes des betreffenden Spinnkopses. Des Weiteren sorgt die in der nutförmigen Aussparung des Handbetätigungsdeckels anstehende Saugluftströmung auch dafür, dass das Fadenende während der Überführung des Spinnkopses straff bleibt bzw. unmittelbar nachdem der Spinnkops seine Abspulstellung erreicht hat, wieder straff gezogen wird.
Auf diese Weise wird sichergestellt, dass der Hilfsgreifer, der anschließend das Fadenende an das Greiferrohr der Spulstelle überführen soll, den zwischen dem Saugluftkanal des Rundmagazins und dem in Abspulstellung positionierten Spinnkops gespannten Fadenstrang stets zuverlässig erfassen und an das Greiferrohr der Spulstelle übergeben kann.The inventive construction of a round magazine with a manual cover and an automatic cover, which are each operable separately and in which in the top of the manual cover a groove-shaped recess is arranged, which forms a connected to the suction air duct of the round magazine air and thread guide channel, closed by the automatic cover is, leads to an aerodynamically advantageous construction.
That is, the prevailing when opening the automatic cover in the groove-shaped recess of the manual cover Saugluftströmung not only ensures that the thread end of the positioned in the transfer position of the round magazine Spinnkopses slides into the groove-shaped recess, but ensures during the transfer of a spinning cop from the round magazine in the unwinding position the winding unit also a reliable separation of the thread end of the respective spinning cop. Furthermore, the suction-air flow impinging in the groove-shaped recess of the manual operating cover also ensures that the thread end remains taut during the transfer of the spinning cop or is pulled back taut immediately after the spinning cop has reached its unwinding position.
In this way, it is ensured that the auxiliary gripper, which is then to transfer the thread end to the gripper tube of the winding unit, always reliably grasp the thread strand stretched between the suction air channel of the round magazine and the spinning cop positioned in the unwinding position and transfer it to the gripper tube of the winding unit.
In vorteilhafter Ausführungsform sind, wie im Anspruch 2 beschrieben, der Handbetätigungsdeckel und der Automatikdeckel an einem Lagerteil angeordnet und jeweils um eine horizontale Schwenkachse begrenzt drehbar gelagert.
Eine solche Ausbildung ermöglicht es, sowohl den
Handbetätigungsdeckel als auch den Automatikdeckel auf einfache Weise jeweils per vertikal gerichteter Krafteinleitung zu öffnen, was nicht beim Handbetätigungsdeckel sondern insbesondere auch im Zusammenhang mit dem Automatikdeckel die Realisierung eines kostengünstigen Antriebsmechanismus' ermöglicht.
Das heißt, aufgrund der horizontalen Schwenkachse des Automatikdeckels können anstelle der bislang benötigten torsionssteifen Drehhebel, einfache, zum Beispiel kostengünstig aus Kunststoff gefertigte, Schubrohre eingesetzt werden.In an advantageous embodiment, as described in
Such training allows both the
Manual operating lid and the automatic lid in a simple manner to open each by vertically directed force, which is not the manual override lid but especially in connection with the automatic lid, the realization of a cost-effective drive mechanism 'allows.
That is, due to the horizontal pivot axis of the automatic cover, simple, for example, inexpensively made of plastic, push tubes can be used instead of torsionally stiff rotary lever previously required.
Wie im Anspruch 3 dargelegt, kommt als Schließmechanismus für den Handbetätigungsdeckel vorzugsweise ein Federelement zum Einsatz, das, zwischen dem Lagerteil und dem Handbetätigungsdeckel eingeschaltet, einerseits den Handbetätigungsdeckel zuverlässig in einer Ausgangsstellung hält, in der der Saugluftkanal luftdicht verschlossen ist, und anderseits ein problemloses Öffnen des Handbetätigungsdeckel per einfachen Handdruck ermöglicht.
Das Lagerteil, an dem sowohl der Handbetätigungsdeckel als auch der Automatikdeckel begrenzt drehbar gelagert sind, ist dabei, wie im Anspruch 4 dargelegt, in vorteilhafter Ausführungsform am Oberrohr des teleskopierbar ausgebildeten Saugluftkanals angeordnet, das seinerseits über einen Klemmblock höhenverstellbar mit dem Unterrohr des Saugluftkanals verbunden ist.
Eine solche Ausbildung ermöglicht es, das erfindungsgemäße Deckelelement, entsprechend der Länge der zu verarbeitenden Spinnkopse, stets optimal zu positionieren.
Mittels des Klemmblockes kann das Oberrohr und damit das Lagerteil beispielsweise stets so angeordnet werden, dass einerseits der Handbetätigungsdeckel für das Bedienpersonal gut zugängig bleibt, anderseits aber verhindert wird, dass es durch eine zu hohe Positionierung des Deckelelements zu einem unbeabsichtigten Abziehen von Fadenmaterial von den Spinnkopsen kommt, was zu Materialverlusten führen würde.As set forth in
The bearing part on which both the manual operating cover and the automatic cover are mounted rotatably limited, it is, as set forth in
Such a design makes it possible to optimally position the cover element according to the invention, corresponding to the length of the spinning cops to be processed.
By means of the clamping block, the top tube and thus the bearing part, for example, always be arranged so that on the one hand the manual cover for the operator remains easily accessible, but on the other hand prevents it by an excessive positioning of the lid member to an unintentional withdrawal of thread material from the spinning cops comes, which would lead to material losses.
Wie im Anspruch 5 beschrieben, ist in vorteilhafter Ausführungsform außerdem vorgesehen, dass auf dem Unterrohr des Saugluftkanals drehfest eine Lagerbuchse befestigt ist, auf der ein Kurvenhebel drehbar gelagert ist, der, durch ein Federelement beaufschlagt, an einer definiert antreibbaren Kurvenscheibe anliegt.
Durch das Federelement wird dabei sichergestellt, dass der Kurvenhebel stets spielfrei an der Kurvenscheibe anliegt, so dass die über die Kurvenscheibe eingeleitete Bewegung vollständig auf den Kurvenhebel weitergegeben wird.As described in
By the spring element is thereby ensured that the cam lever always abuts without play on the cam, so that the introduced via the cam movement is completely passed on to the cam lever.
Wie im Anspruch 6 beschrieben, weist der Kurvenhebel in vorteilhafter Ausbildung eine helixförmig ausgebildete Anlauffläche auf, die mit einer entsprechend helixförmig gestalteten Anlauffläche einer auf dem Unterrohr des Saugluftkanals drehfest, jedoch axial verschiebbar geführten Schubbuchse korrespondiert. Das bedeutet, die über die Kurvenscheibe eingeleitete Drehbewegung wird durch den Kurvenhebel in Verbindung mit der Schubbuchse in eine Schubbewegung, deren Kraftrichtung parallel zum Saugluftkanal verläuft, umgewandelt und kann anschließend direkt zur Ansteuerung des Automatikdeckels benutzt werden.As described in
Wie in den Ansprüchen 7 und 8 ausgeführt, ist die Schubbuchse über ein mehrteiliges Druckrohr an den Automatikdeckel angeschlossen, wobei ein Unterrohr und ein Oberrohr des Druckrohres über eine werkzeuglos einstellbare Klemmgewindeeinrichtung verbunden sind. Die Klemmgewindeeinrichtung gewährleistet dabei auf unkomplizierte Weise eine exakte Anpassung der Länge des Druckrohres entsprechend der gewählten Einstellhöhe des erfindungsgemäßen Deckelelements.As set forth in
Gemäß Anspruch 9 ist in vorteilhafter Ausführungsform außerdem vorgesehen, dass das Unterrohr des Druckrohres im Klemmblock des Saugluftkanals axial verschiebbar geführt ist.
Eine solche Führung des Unterrohres im Klemmblock gewährleistet auf einfache Weise und bei jeder Einstellhöhe eine sichere und saubere Führung des Druckrohres und damit eine ordnungsgemäße Übertragung der über die Schubbuchse eingeleiteten Schubkraft.According to
Such a leadership of the down tube in the terminal block ensured in a simple manner and at any setting height safe and clean management of the pressure tube and thus a proper transmission of the thrust bushing introduced via the thrust.
Um zu verhindern, dass es bei Blockierungen des Automatikdeckels zu Beschädigungen kommen kann, ist gemäß Anspruch 10 außerdem vorgesehen, dass das Oberrohr des Druckrohres indirekt an den Automatikdeckel angeschlossen ist.In order to prevent that it may cause damage in blockages of the automatic cover, is also provided according to
Das heißt, zwischen das Oberrohr und den Automatikdeckel ist ein Federelement eingeschaltet, das zusammengedrückt wird, wenn über den Schrittmotor ein Schaltvorgang eingeleitet wird, obwohl der Automatikdeckel blockiert ist.That is, between the top tube and the automatic cover, a spring element is turned on, which is compressed when a switching operation is initiated via the stepping motor, although the automatic cover is blocked.

Wie ersichtlich, besteht der insgesamt mit der Bezugszahl 13 gekennzeichnete Saugluftkanal aus einem Unterrohr 30 und einem verschiebbar im Unterrohr 30 geführten Oberrohr 29.
Auf dem Unterrohr 30, das mit seinem unteren Ende in einem (nicht näher dargestellten) Gehäuse des Rundmagazins 3 festgelegt ist, ist im Bereich des oberen Endes ein Klemmblock 31 angeordnet, der eine definierte Einstellung der Länge des Saugluftkanals 13 und damit der Höhe des Deckelelementes 12 ermöglicht.
Das heißt, mittels des Klemmblockes 31 kann die Ausfahrlänge des Oberrohrs 29 und damit die Einbauhöhe eines am oberen Ende des Oberrohrs 29 befestigten Lagerteils 23 exakt vorgegeben werden.The

An dieser Kurvenscheibe 35 liegt, durch ein Federelement 34 beaufschlagt, ein Kurvenhebel 33 an, der über eine Lagerbuchse 32 drehbar auf dem Unterrohr 30 des Saugluftkanals 13 angeordnet ist. Der Kurvenhebel 33 weist eine nach oben gerichtete helixförmige Anlauffläche 39 auf, die mit einer entsprechenden, nach unten gerichteten helixförmigen Anlauffläche 40 einer Schubbuchse 41 korrespondiert, die ihrerseits drehfest, jedoch axial verschiebbar, auf dem Unterrohr 30 des Saugluftkanals 13 angeordnet ist.
An der Schubbuchse 41 stützt sich ein zweiteiliges Druckrohr 42 ab, wobei das im Klemmblock 31 axial verschiebbar geführte Unterrohr 43 des Druckrohres 42 mit dem zugehörigen Oberrohr 44 über eine werkzeuglos verstellbare Klemmgewindeeinrichtung 45 verbunden ist. Das Oberrohr 44 ist schließlich über ein Federelement 46 so mit dem Automatikdeckel 19 verbunden, dass, wie in

Wenn das Rundmagazin 3 im Zuge eines Spinnkopswechsels um eine Aufnahmetaschenteilung weiter getaktet wird und dabei ein frischer Spinnkops 4 aus dem Rundmagazin 3 an die Abspulstellung AS der Spulstelle 2 überführt wird, gleitet das in der Ansaugöffnung 50 des Saugluftkanals 13 fixierte Fadenende 6 des betreffenden Spinnkopses 4 in die nutartige Aussparung 22 und wird dort, da gleichzeitig der Automatikdeckel 19 etwas geöffnet hat, einer relativ starken Saugluftströmung ausgesetzt.
Die Saugluftströmung sorgt dafür, dass das Fadenende 6 des inzwischen auf einem Aufnahmedorn 25 angeordneten Spinnkopses 4, das zwischen Spinnkops 4 und Deckelelement 12 einen Fadenstrang bildet, stramm gezogen bleibt bzw. stramm gezogen wird und von einem spulstelleneigenen Hilfsgreifer 24 problemlos an das Greiferrohr 16 der Spulstelle 2 übergeben werden kann.When the
