Die Erfindung bezieht sich auf eine Vorspinnmaschine mit einer Vorrichtung zum selbsttätigen Auswechseln voller Vorgarnspulen gegen leere Vorgarnhülsen nach dem Oberbegriff des Anspruchs 1 bzw. 4.The invention relates to a roving machine with a Device for automatic replacement of full roving bobbins against empty roving sleeves according to the preamble of claim 1 or 4th

Als nächstliegender Stand der Technik ist bereits eine Vorspinnmaschine mit zwei Flügelreihen bekannt (DE 195 02 586 A1), welche so konzipiert ist, daß die Hängewagenzüge quer zur Längsrichtung der Vorspinnmaschine in nur je zwei Flügel, und zwar in je einen Flügel der hinteren Flügelreihe und einem Flügel der vorderen Flügelreihe bewegbar sind. Hierzu können Führungsschienen Anwendung finden, welche entweder feststehend oder teleskopierbar ausgebildet sind bzw. wegschwenkbare Abschnitte aufweisen.A roving machine is already included as the closest prior art two rows of wings known (DE 195 02 586 A1), which designed so is that the hanging trolley trains transverse to the longitudinal direction of the Roving machine in only two wings, one in each Wing of the rear row of wings and one wing of the front Wing row are movable. For this purpose, guide rails Find application which are either fixed or telescopic are formed or have sections pivotable away.

Weiterer Stand der Technik bezieht sich auf eine Vorrichtung (DE 42 29 296 A1), bei welcher ein Hängewagenzug an einer durch die Flügel verlaufenden Führungsschiene in die Wechselstellung bewegt wird. Hierzu sind unter den Köpfen der Flügel und/oder unter der Flügelbank der Vorspinnmaschine speziell ausgebildete Führungsglieder angeordnet, welche insbesondere in Querstellung der Flügel zur Längsachse der Vorspinnmaschine eine einen Hängewagenzug tragende Führungsschiene bilden.Another state of the art relates to a device (DE 42 29 296 A1), in which a hanging wagon train on one through the wing running guide rail in the change position is moved. For this purpose, the wings are under the heads and / or specifically under the wing bench of the roving machine trained guide members arranged, which in particular in the transverse position of the wing to the longitudinal axis of the roving machine form a guide rail carrying a suspension trolley.

Weiterhin ist vorgeschlagen worden, bei einer Vorspinnmaschine entlang der mindestens einen Reihe von Flügeln eine Führungsschiene anzubringen, in welcher ein Hängewagenzug einfahrbar ist. Durch Heb- und Senkbewegungen der Spulenbank können die Spulen aus dieser in Hängehalter des Hängewagenzuges umgesetzt und Hülsen von den Hängehaltern in die Spulenbank versetzt werden. Die Spulenbank und/oder die Führungsschienen können vor- oder zurückverschiebbar sein. Fest angeordnete Führungsschienen können an der Unterseite der Flügelbank sitzen; bewegbare Führungsschienen sind im Bereich unterhalb der Flügel angeordnet.It has also been proposed in a roving machine a guide rail along the at least one row of wings to attach, in which a hanging car train retractable is. By lifting and lowering the bobbin, the Coils from this implemented in the hanging bracket of the hanging trolley and sleeves from the hanging brackets in the coil bank become. The coil bank and / or the guide rails can be moved forward or backward. Fixed guide rails can sit on the underside of the sash; movable Guide rails are in the area below the wing arranged.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Vorrichtung nach den Merkmalen des Oberbegriffs des Anspruchs 1 so auszubilden, daß über eine einfach aufgebaute Vorrichtung die Hängewagenzüge bezüglich der Führungsschienen ein- bzw. ausfahrbar sind.The object of the present invention is a Device according to the features of the preamble of the claim 1 trained so that a simple structure the suspension trolley trains with respect to the guide rails are extendable.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 bzw. 4 gelöst. Hierdurch ergibt sich der Vorteil einer funktionssicher arbeitenden Vorrichtung zum selbsttätigen Auswechseln voller Vorgarnspulen gegen leere Vorgarnhülsen, wobei durch die Anordnung der Führungsschienen gewährleistet ist, daß die Hängewagenzüge auf kurzem Wege und damit rasch quer zur Längsrichtung der Vorspinnmaschine in den Bereich der Flügelreihen einfahren bzw. ausfahren können.This object is achieved with the features of claims 1 and 4 respectively solved. This gives the advantage of being reliable working device for automatic replacement full of roving bobbins against empty roving tubes, taking through the arrangement of the guide rails ensures that the Overhead trolleys on a short path and therefore quickly across the length of the roving machine in the area of the wing rows can retract or extend.

Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous further developments result from the subclaims.

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 roving machine 1 with drafting devices 2, one fixed wing bench 3 and one by means of a, not shown, controllable drive functionally up and down movable bobbin 4 with bobbins 40 and 40 '. On the Coil bank 4 are a front according to Fig. La to lc Longitudinal or coil row I and a rear longitudinal or coil row II, the front coil row I the coil carrier 40 and the rear coil row II contains the coil carrier 40 '. These carry roving bobbins 12, which after work are to be exchanged for empty roving sleeves 13. Find this Hanging carriage trains 10 application, which in guide rails 5 in essentially transversely to the longitudinal direction of the roving machine or extend and thus into the area of the front and rear Rows of coils I and II get out of them become.

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 guide rails 5 are arranged laterally from vertical planes E 1 -E 1 which contain the two coil carriers 40, 40 '. They are in particular arranged according to FIGS.

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 hanging trolley trains 10 are in the guide rails 5 in the area of the front and rear rows of coils I and II retracted. At the step after Fig. 1a is the coil bank 4 with the full bobbins 12 by one certain amount lowered, the suspension trolley 10 in the guide rail 5 are retracted so far that their empty hangers 15 in the vertical planes of the coils 12 stand in the two coil rows I and II.

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 coil bank 4 by an indicated distance b, the empty hangers 15 and the full coils 12 are vertically one above the other. The coil bank 4 is thus laterally displaceable such that the vertical planes E 1 -E 1 containing the coil carriers 40, 40 'coincide with the vertical planes E 2 -E 2 running through the respectively assigned guide rails 5.

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 coil bank 4 is raised so far that the full Coils 12 in the empty hanging holder 15 of the hanging trolley trains 10 can be hung.

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 spool bank 4 is lowered again and the hanging trolley trains 10 move so far forward that now with empty sleeves 13 equipped hanging holder 15 over the (empty) Coil spindles 25 stand (Fig. Lb). Now the coil bank can 4 are raised again and from the hanging trolley 10 remove the empty roving sleeves 13, which for the next Workflow needed. Then the hanging car trains 10 withdrawn from the wing and coil area, the Coil bank 4 moved back to its normal working position, whereupon the roving machine can start again.

Aus Fig. 1c ist ersichtlich, daß die geraden Führungsschienen 5 in den Bereich der Spulenreihen I und II verlaufen, wobei 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 straight guide rails 5 run in the area of the coil rows I and II, wherein the movable in the guide rails 5, as rigid rods trained hanging trolley trains 10 with a common connecting rod 17 and a drive element 18 are connected. This allows the hanging trolley trains 10 in the guide rails 5 retract and extend together, i.e. in the field of Spool rows I and II or in the behind the roving machine move lying change area, in the to the next Change process by hand or by an automatic device the full spools are removed from the hanging brackets and these can be filled with empty sleeves again.

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 coil bank 4, for example via a rack 30 and a pinion 31 and a drive 32 is laterally displaceable by the amount b the coil spindles 25 in the vertical plane of the hanging holder 15 of the relevant suspension carriage train 10 to move or off to remove this.

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 wings 22. During the changing process, they are in the vertical planes E 1 -E 1 , which contain the two coil supports 40, 40 ', to which the guide rails 5' are each assigned. They are designed as rigid rails and form the hanging trolley trains 10.

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 support members 20 be guided at the bottom of the wing bench 3 are arranged. In the variant of FIG. 2b the guide rails 5 '' are limited to the area inside the machine frame, the "hanging car trains" are like that rigid that they are cantilevered in the area of the wings and coils can drive up.

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. 2a 10 again so far in the area of the coil rows I and II retracted that an empty hanger 15 above each full bobbin 12 stored in the coil bank 4 located. Now this coil bank 4 can be raised and the full roving bobbins 12 can on the hanging bracket 15 to the Hanging carriage trains 10 are handed over.

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 roving bobbins 12 above the concerned Spindles of the coil bank 4 are located. This then drives back up and takes over from the trolley 10 empty roving sleeves 13.

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 horizontal Axle 28 are pivotable to from the working position to be able to be moved out into the dotted rest position. Otherwise, the procedure is identical to that according to Fig. 2a.

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 Wing 22, but above the coil spindles 25, as are also offset laterally to the wings and coils. The Spool bank 4 is again laterally displaceable by the distance b. The sequence of the change process is without further from the understanding of the processes according to the embodiments 1 to 1b and 2 to 2b.

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 straight guide rails 5 and accordingly be designed as rigid rods. In many cases is for the oblique course of these guide rails 5 through the machine frame, however, no space. The guide rails 5 must then be angled and the hanging trolley trains 10 must then actually in a known manner, not shown here Way out of "trains" with flexibly coupled "wagons" consist.

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 coil spindles 25, which the sleeves 13 or coils 12 at their rapid Lead rotation. This guiding of the coils and sleeves can also done by wing spindles arranged on the wings, that protrude from above into the sleeves or coils. The course of the The change process does not change.
