Fig. 1 zeigt eine Vorspinnmaschine 1 mit Streckwerken 2, einer
ortsfesten Flügelbank 3 sowie einer mittels eines nicht dargestellten,
steuerbaren Antriebs funktionsgerecht auf und ab
bewegbaren Spulenbank 4 mit Spulenträgern 40 und 40'. Auf der
Spulenbank 4 befinden sich gemäß Fig. la bis lc eine vordere
Längs- bzw. Spulenreihe I sowie eine hintere Längs- bzw. Spulenreihe
II , wobei die vordere Spulenreihe I die Spulenträger
40 und die hintere Spulenreihe II die Spulenträger 40' enthält.
Diese tragen Vorgarnspulen 12, welche nach Arbeitsablauf
gegen leere Vorgarnhülsen 13 auszutauschen sind. Hierzu finden
Hängewagenzüge 10 Anwendung, welche in Führungsschienen 5 im
wesentlichen quer zur Längsrichtung der Vorspinnmaschine ein-
bzw. ausfahren und damit in den Bereich der vorderen und hinteren
Spulenreihen I und II gelangen bzw. aus diesen herausgeführt
werden.Fig. 1 shows a
Die Führungsschienen 5 sind nach Fig. lc seitlich von senkrechten
Ebenen E1-E1 angeordnet, welche die beiden Spulenträger
40, 40' enthalten. Sie sind hierbei insbesondere nach Fig. 1a
und 1b feststehend an der Unterseite der Flügelbank 3 angeordnet. According to FIG. 1c, the
Gemäß Fig. 1 und la sind die Hängewagenzüge 10 in den Führungsschienen
5 in den Bereich der vorderen und hinteren Spulenreihen
I und II eingefahren. Bei dem Verfahrensschritt nach
Fig. 1a ist die Spulenbank 4 mit den vollen Spulen 12 um einen
bestimmten Betrag abgesenkt, wobei die Hängewagenzüge 10 in
der Führungsschiene 5 so weit eingefahren sind, daß deren
leere Hängehalter 15 in den senkrechten Ebenen der Spulen 12
in den beiden Spulenreihen I und II stehen.1 and la, the
Nach Verfahren der Spulenbank 4 um eine angedeutete Distanz b
stehen die leeren Hängehalter 15 und die vollen Spulen 12
senkrecht übereinander. Die Spulenbank 4 ist also seitlich so
verschiebbar, daß die die Spulenträger 40, 40' enthaltenden
senkrechten Ebenen E1-E1 mit durch die jeweils zugeordneten
Führungsschienen 5 verlaufenden, senkrechten Ebenen E2-E2 zusammenfallen.After moving the
Nunmehr wird die Spulenbank 4 so weit angehoben, daß die vollen
Spulen 12 in die leeren Hängehalter 15 der Hängewagenzüge
10 eingehängt werden.Now the
Danach wird die Spulenbank 4 wieder abgesenkt und die Hängewagenzüge
10 so weit nach vorn verfahren, daß nunmehr die mit
leeren Hülsen 13 bestückten Hängehalter 15 über den (leeren)
Spulenspindeln 25 stehen (Fig. lb). Nunmehr kann die Spulenbank
4 wieder angehoben werden und von dem Hängewagenzug 10
die leeren Vorgarnhülsen 13 entnehmen, welche für den nächsten
Arbeitsablauf benötigt werden. Danach werden die Hängewagenzüge
10 aus dem Flügel- und Spulenbereich zurückgezogen, die
Spulenbank 4 in ihre normale Arbeitsstellung zurückbewegt,
worauf die Vorspinnmaschine ihre Arbeit wieder aufnehmen kann.Then the
Aus Fig. 1c ist ersichtlich, daß die geraden Führungsschienen

die in den Führungsschienen 5 bewegbaren, als starre Stangen
ausgebildeten Hängewagenzüge 10 mit einer gemeinsamen Verbindungsstange
17 sowie einem Antriebselement 18 verbunden sind.
Damit lassen sich die Hängewagenzüge 10 in den Führungsschienen
5 gemeinsam ein- und ausfahren, d.h. in dem Bereich der
Spulenreihen I und II bzw. in den hinter der Vorspinnmaschine
liegenden Wechselbereich bewegen, in dem bis zum nächsten
Wechselvorgang von Hand oder durch eine selbsttätige Vorrichtung
die vollen Spulen aus den Hängehaltern entnommen und
diese wieder mit leeren Hülsen bestückt werden können.From Fig. 1c it can be seen that the
Aus Fig. lc ist außerdem erkennbar, daß die Spulenbank 4 beispielsweise
über eine Zahnstange 30 sowie ein Ritzel 31 und
einen Antrieb 32 um den Betrag b seitlich verschiebbar ist, um
die Spulenspindeln 25 in die senkrechte Ebene der Hängehalter
15 des betreffenden Hängewagenzuges 10 zu bewegen bzw. aus
diesem zu entfernen.From Fig. Lc it can also be seen that the
Bei der Ausführungsform der Fig. 2 ist die Spulenbank nicht
seitlich verschiebbar. Die Führungsschienen 5' sind zum Wechselvorgang
in eine unterhalb der Unterkante der Flügel 22
verlaufenden Ebene bewegbar. Sie stehen beim Wechselvorgang in
den senkrechten Ebenen E1-E1, welche die beiden Spulenträger
40, 40' enthalten, denen die Führungsschienen 5' jeweils zugeordnet
sind. Sie sind als starre Schienen ausgebildet und
bilden die Hängewagenzüge 10.In the embodiment of FIG. 2, the coil bank cannot be moved laterally. The guide rails 5 'can be moved for changing in a plane running below the lower edge of the
Die Hängewagenzüge können hierbei gemäß Fig. 2a durch Stützglieder
20 geführt sein, die an der Unterseite der Flügelbank
3 angeordnet sind. In der Ausbildungsvariante der Fig. 2b
beschränken sich die Führungsschienen 5'' auf den Bereich
innerhalb des Maschinengestells, die "Hängewagenzüge" sind so
starr, daß sie freitragend in den Bereich der Flügel und Spulen
vorfahren können. The suspension trolley trains can here according to Fig. 2a by
In der in Fig. 2a dargestellten Position sind die Hängewagenzüge
10 wieder so weit in den Bereich der Spulenreihen I und
II eingefahren, daß sich jeweils ein leerer Hängehalter 15
über jeder, in der Spulenbank 4 lagernden vollen Spule 12
befindet. Nunmehr kann diese Spulenbank 4 angehoben und die
vollen Vorgarnspulen 12 können über die Hängehalter 15 an die
Hängewagenzüge 10 übergeben werden.The suspension trolley trains are in the position shown in FIG.
Anschließend werden die Hängewagenzüge 10 nach vorn so verfahren,
daß sich die leeren Vorgarnspulen 12 oberhalb der betreffenden
Spindeln der Spulenbank 4 befinden. Diese fährt dann
wieder nach oben und übernimmt von dem Hängewagenzug 10 die
leeren Vorgarnhülsen 13.Then the hanging carriage trains 10 are moved forward so
that the empty
Bei der Ausführungsform nach Fig. 2b sind die Hängewagenzüge
10 in den Führungsschienen 5'' verfahrbar, die um eine horizontale
Achse 28 schwenkbar sind, um aus der Arbeitsposition
in die gestrichelte Ruheposition herausbewegt werden zu können.
Im übrigen ist der Verfahrensablauf identisch mit dem
nach Fig. 2a.In the embodiment according to FIG. 2b, the hanging trolley trains are
10 movable in the guide rails 5 '' around a
Die Ausführungsform der Fig. 3 stellt eine Kombination der
Ausführungsformen der Fig. 1 und 2 dar: Die Hängewagenzüge
bewegen sich hierbei entlang Spuren, die sowohl unterhalb der
Flügel 22, aber oberhalb der Spulenspindeln 25 liegen, als
auch seitlich zu den Flügeln und Spulen versetzt sind. Die
Spulenbank 4 ist hier wieder um die Distanz b seitlich verschiebbar.
Der Ablauf des Wechselvorganges ergibt sich ohne
weiteres aus dem Verständnis der Abläufe gemäß den Ausführungsformen
der Fig. 1 bis 1b und 2 bis 2b.The embodiment of FIG. 3 represents a combination of the
Embodiments of FIGS. 1 and 2: The hanging trolley trains
move along tracks that are both below the
Wie insbesondere aus Fig. 1c erkennbar, können die Hängewagenzüge
sich in geradlinigen Führungsschienen 5 bewegen und demgemäß
als starre Stangen ausgebildet sein. In vielen Fällen
ist für den schrägen Verlauf dieser Führungsschienen 5 durch
das Maschinengestell jedoch kein Raum. Die Führungsschienen 5
müssen dann abgewinkelt sein und die Hängewagenzüge 10 müssen
dann tatsächlich in an sich bekannter, hier nicht näher dargestellter
Weise aus "Zügen" mit flexibel gekuppelten "Wagen"
bestehen.As can be seen in particular from Fig. 1c, the hanging trolley trains
move in
Wie aus Fig. 1b erkennbar, weist die Spulenbank 4 Spulenspindeln
25 auf, die die Hülsen 13 bzw. Spulen 12 bei ihrer raschen
Drehung führen. Dieses Führen der Spulen und Hülsen kann
auch durch an den Flügeln angeordnete Flügelspindeln erfolgen,
die von oben in die Hülsen bzw. Spulen ragen. Der Ablauf des
Wechselvorganges ändert sich dadurch nicht.As can be seen from FIG. 1b, the coil bank has 4
