Description

Die Erfindung betrifft ein Verfahren zum Anwickeln eines Warenbaums in einem Transportgerät für eine Weberei. Das Anwickeln eines neuen Warenbaums ist beim Warenbaumwechsel an einer Webmaschine nötig, da das Gewebe zwischen dem vollen Warenbaum und der Webmaschine durchtrennt werden muss, wenn der Warenbaum durch das Transportgerät von der Webmaschine weggebracht werden soll.The invention relates to a method for winding a goods tree in a transport device for a weaving mill. The winding of a new goods tree is necessary when changing the goods tree on a weaving machine, since the fabric between the full goods tree and the weaving machine has to be severed if the goods tree is to be removed from the weaving machine by the transport device.

Aus JP-A-61 023059 (= US-A-4 606 381) ein Verfahren zum Anwickeln eines neuen Warenbaums bekannt, bei dem das freie Ende der Gewebebahn durch Druckluft zum Anliegen an den neuen Warenbaum gebracht wird, wobei gleichzeitig durch Saugluft, welche durch Bohrungen im Warenbaum in diesen einströmt, das freie Ende der Gewebebahn an der Oberfläche des Warenbaums gehalten werden soll. Bei grösseren Gewebebreiten führt dies zu starken Luftströmungen, wenn gleichzeitig aus einer grösseren Anzahl von Düsen Luft ausgeblasen bzw. durch eine grosse Anzahl von Saugöffnungen Luft angesaugt wird. Dabei kann es zur Aufwirbelung von Textilfasern in der Maschine kommen, wodurch die Gewebequalität und die Maschinenfunktion beeinträchtigt werden können. Die Funktion des Anwickelns ist möglicherweise nicht bei allen Gewebearten, insbesondere bei glatten Geweben, gewährleistet.From JP-A-61 023059 (= US-A-4 606 381) a method for winding a new fabric is known, in which the free end of the fabric web is brought into contact with the new fabric by compressed air, while at the same time by suction air which flows through holes in the fabric, the free end of the fabric web is to be held on the surface of the fabric. With larger fabric widths, this leads to strong air currents if air is simultaneously blown out of a larger number of nozzles or air is sucked in through a large number of suction openings. This can whirl up textile fibers in the machine, which can affect fabric quality and machine function. The wrapping function may not be on all types of fabric, especially smooth fabrics, guaranteed.

Es ist Aufgabe der vorliegenden Erfindung, das Anwickeln ohne Druck- bzw. Saugluft zu bewerkstelligen und dabei eine hohe Funktionssicherheit zu erreichen. Zur Lösung dieser Aufgabe dienen die Merkmale gemäss kennzeichnen von Anspruch 1 und 3.It is an object of the present invention to accomplish the winding without compressed or suction air and to achieve a high level of functional reliability. To achieve this object, the features according to characterize claims 1 and 3.

Nachdem das Umfahren des neuen Warenbaums durch den Anwickelbaum beendet ist, werden Warenbaum und Anwickelbaum unter Zwischenlage der Faltvorrichtung und des aufzuwickelnden Gewebes gegeneinander gepresst. Während das freie Ende V-förmig gefaltet ist, wobei die V-Form innen durch die Faltvorrichtung und aussen durch Warenbaum und Anwickelbaum gebildet wird, geht die aufzuwickelnde Gewebebahn beim freien Ende der Faltvorrichtung tangential vom Anwickelbaum auf den neuen Warenbaum über.After the wrapping tree has finished driving around the new goods tree, the goods tree and wrapping tree are pressed against one another with the interposition of the folding device and the fabric to be wound up. While the free end is folded in a V-shape, the V-shape being formed on the inside by the folding device and on the outside by the fabric tree and wrapping tree, the web of fabric to be wound up is tangentially transferred from the wrapping tree to the new fabric tree at the free end of the folding device.

Durch Drehen des neuen Warenbaums in Richtung des freien Endes der anliegenden Faltvorrichtung wird das V-förmig gelegte freie Ende der Gewebebahn zwischen der Oberfläche des neuen Warenbaums und der nächsten Gewebelage von der Faltvorrichtung abgezogen und fest an den Umfang des Warenbaums gedrückt. Dadurch wird ein rutschfreies Anwickeln des abgeschnittenen Gewebes auf dem neuen Gewebebaum erreicht. Das Anwickeln kann auch ohne V-Falte durchgeführt werden, wenn das freie Ende der Faltvorrichtung praktisch deckungsgleich mit dem freien Ende der Gewebebahn am neuen Warenbaum aufliegt, so dass keine Faltenbildung eintritt.By rotating the new goods tree in the direction of the free end of the adjacent folding device, the V-shaped free end of the fabric web between the surface of the new goods tree and the next fabric layer is pulled off the folding device and pressed firmly against the circumference of the goods tree. This ensures that the cut fabric is wound onto the new fabric tree without slipping. The wrapping can also be carried out without a V-fold if the free end of the folding device lies practically congruent with the free end of the fabric web on the new fabric tree, so that no wrinkling occurs.

Im folgenden wird die Erfindung anhand der Figuren im Detail beschrieben.The invention is described in detail below with reference to the figures.

In Fig. 1 ist der Aufbau des Transportgerätes 102 zum Teil schematisch dargestellt. Es ist in Fahreinheiten 1a und 1b mit Rädern zum Tragen des ganzen Gerätes und eine dazwischen angeordnete Trageinheit 2 gegliedert. Die Fahreinheiten enthalten je einen Fahrantrieb, der das Transportgerät entlang einer Fahrspur im Websaalboden durch die Weberei führt. Die Trageinheit ist mit einem vollen Warenbaum 50, einem leeren Warenbaum 51, einem Anwickelbaum 70 und mit Greifarmen 40a, 40b gezeichnet. Weiterhin ist eine Schneidvorrichtung 10 angedeutet, welche in Längsrichtung des Transportgerätes 102 bewegbar ist. Eine Traverse 21 verbindet den rechten Seitenteil 20a mit dem linken Seitenteil 20b, wobei die Traverse 21 gegenüber dem Seitenteil 20b verschiebbar ist. Zwischen den Seitenteilen 20a und 20b befinden sich mehrere Teleskopstangen 225, mit welchen die Länge des Transportgerätes für den jeweils zu bedienenden Webmaschinentyp angepasst werden kann. Unten an den Seitenteilen 20a und 20b befinden sich ausfahrbare Stützen 30a, 30b, über welche die Trageinheit 2 auf dem Websaalboden abgestützt wird, während der Warenbaumwechsel stattfindet.In Fig. 1 the structure of the transport device 102 is partially shown schematically. It is divided into driving units 1a and 1b with wheels for carrying the entire device and a carrying unit 2 arranged between them. The travel units each contain a travel drive, which Transport device leads through the weaving mill along a lane in the weaving room floor. The carrying unit is drawn with a full goods tree 50, an empty goods tree 51, a winding tree 70 and with gripping arms 40a, 40b. Furthermore, a cutting device 10 is indicated, which is movable in the longitudinal direction of the transport device 102. A cross member 21 connects the right side part 20a to the left side part 20b, the cross member 21 being displaceable relative to the side part 20b. Between the side parts 20a and 20b there are several telescopic rods 225, with which the length of the transport device can be adapted for the type of weaving machine to be operated. At the bottom of the side parts 20a and 20b are extendable supports 30a, 30b, by means of which the support unit 2 is supported on the weaving room floor while the goods tree is being changed.

In Fig. 2 befindet sich das Transportgerät 102 in einer Ansicht in Längsrichtung neben einer Webmaschine 500a. In der Webmaschine 500a werden Kettfäden 512 einer Weblade 503 zugeführt, wo der Schusseintrag erfolgt. Ueber einen Warenabzug 504 und Umlenkstangen 505 wird das Gewebe 510 zu einem Warenbaum 50 gelenkt und dort aufgewickelt. Die erwähnten Elemente der Webmaschine sind zwischen Wangen 506 gelagert, welche durch Rohrtraversen 507b und Winkeltraversen 508b zusammengehalten werden. Die Wangen 506 sind auf Fussschienen 509 abgestützt. Das Gewebe wird bis zu einem höchstzulässigen Durchmesses des Tuchwickels auf den Warenbaum 50 aufgewickelt. Wenn dieser Zustand erreicht ist, beordert eine logistische Steuereinrichtung der Weberei das Transportgerät 102 zur betreffenden Webmaschine 500a.2, the transport device 102 is located in a view in the longitudinal direction next to a weaving machine 500a. In the loom 500a, warp threads 512 are fed to a sley 503, where the weft insertion takes place. The fabric 510 is directed to a goods tree 50 via a goods take-off 504 and deflecting rods 505 and is wound up there. The elements of the weaving machine mentioned are mounted between cheeks 506, which are held together by tubular cross members 507b and angular cross members 508b. The cheeks 506 are supported on foot rails 509. The fabric is wound onto the fabric tree 50 up to a maximum permissible diameter of the cloth roll. When this state is reached, a logistic control device of the weaving mill orders the transport device 102 to the relevant weaving machine 500a.

In Fig. 2 ist der Zustand im Transportgerät 102 nach der Entnahme des vollen Warenbaums 50 aus der Webmaschine und vor dem Anwickeln eines neuen Warenbaums 51 dargestellt. Die Greifarme 40a, 40b mit den gegeneinander beweglichen Schenkeln 42 und 43 haben den vollen Warenbaum aus der Webmaschine aus der gestrichelten Position herausgenommen und in eine Tragvorrichtung 52a im Transportgerät 102 eingesetzt. Der Anwickelbaum 70 wurde aus der unteren Position 70' angehoben und wird gerade in der ausgezogenen Stellung von den Greifarmen 40a und 40b freigegeben. Während des Anhebens des Anwickelbaums 70 hat das Gewebe 510 eine Schlaufe gebildet, da es vom Anwickelbaum nach oben gezogen wurde. Der Anwickelbaum wird in der gezeichneten Position von einem Manipulator 71 übernommen. Ein Gehäuse 710 des Manipulators ist um die Achse des neuen Warenbaums 51 drehbar gelagert. Am Gehäuse 710 sitzt drehbar gelagert ein Hebel 711, dessen rechtes Ende durch eine Druckfeder 712 nach unten bzw. aussen gedrückt wird. Wenn die Rolle 713 am rechten Ende des Hebels 711 bei Drehung des Gehäuses 710 im Uhrzeigersinn auf dem Kurvensegment 714 aufläuft, wird der Hebel 711 relativ zum Gehäuse 710 entgegen dem Uhrzeigersinn um seine Achse geschwenkt. Dabei gelangt eine Mulde 715 am anderen Ende des Hebels 711 in eine Stellung, in der sie den Anwickelbaum 70 übernehmen kann. Der Manipulator 71 ist auf beiden Seiten 20a und 20b des Transportgerätes angeordnet. Nach der Uebernahme des Anwickelbaums durch den Manipulator 71 dreht dieser entgegen dem Uhrzeigersinn um die Achse des Warenbaums 51. Sobald die Rolle 713 ausser Kontakt mit dem Kurvensegment 714 ist, wird der Hebel 711 durch die Feder 712 wieder im Uhrzeigersinn bewegt. Dadurch gelangt die Oberfläche des Anwickelbaums 70 an die Oberfläche des neuen Warenbaums 51. Nun wird der Anwickelbaum 70 durch den Manipulator 71 entgegen dem Uhrzeigersinn um den Warenbaum 51 herumgeführt.2 shows the state in the transport device 102 after the full goods tree 50 has been removed from the weaving machine and shown before starting a new goods tree 51. The gripping arms 40a, 40b with the legs 42 and 43 which are movable relative to one another have taken the full goods tree out of the weaving machine from the dashed position and inserted it into a carrying device 52a in the transport device 102. The winding tree 70 has been raised from the lower position 70 'and is just released in the extended position by the gripping arms 40a and 40b. During the lifting of the winding tree 70, the fabric 510 has formed a loop because it has been pulled up by the winding tree. The winding tree is taken over by a manipulator 71 in the position shown. A housing 710 of the manipulator is rotatably mounted about the axis of the new goods tree 51. A lever 711 is rotatably mounted on the housing 710, the right end of which is pressed downwards or outwards by a compression spring 712. When the roller 713 at the right end of the lever 711 runs on the cam segment 714 when the housing 710 rotates clockwise, the lever 711 is pivoted about its axis relative to the housing 710 in a counterclockwise direction. A trough 715 at the other end of the lever 711 comes into a position in which it can take over the winding tree 70. The manipulator 71 is arranged on both sides 20a and 20b of the transport device. After the take-up tree has been taken over by the manipulator 71, it rotates counterclockwise around the axis of the goods tree 51. As soon as the roller 713 is out of contact with the cam segment 714, the lever 711 is moved again clockwise by the spring 712. As a result, the surface of the winding tree 70 comes to the surface of the new goods tree 51. Now, the manipulation tree 70 is guided around the goods tree 51 counterclockwise by the manipulator 71.

Die Figurenfolge 3a - 3h zeigt den Anwickelvorgang. Nach Anpressen des Anwickelbaums 70 am Warenbaum 51 (Fig. 3a) wird der Warenbaum 51 kurzzeitig im Uhrzeigersinn angetrieben, wodurch der mit ihm in Kontakt stehende Anwickelbaum eine Tuchreserve zur Webmaschine hin bildet. Dabei wird das für die Bildung der Tuchreserve benötigte Gewebe vom vollen Warenbaum 50 abgewickelt (Fig. 3b). Nachdem der Anwickelbaum 70 in eine Position oberhalb des Warenbaums 51 gelangt ist (Fig. 3c), wird eine Schneideinrichtung 10 von rechts an das Gewebe herangeführt, welches dann an dieser Stelle durchtrennt wird. Die Schneideinrichtung 10 wird dann wieder in ihre ursprüngliche Position gefahren, während der Anwickelbaum 70 weiter nach links bewegt wird. Das freie Ende 510' des Gewebes fällt dann über den neuen Warenbaum 51 herab, worauf dieser sich soweit im Uhrzeigersinn dreht, bis eine bestimmte freie Tuchlänge 510' vom Warenbaum herabhängt. Der Anwickelbaum 70 befindet sich nach wie vor in Kontakt mit dem Warenbaum 51, weshalb er eine Gegendrehung vollführt (Fig. 3d). Nachdem der Warenbaum 51 wieder zum Stillstand gekommen ist, wird der Anwickelbaum 70 im Uhrzeigersinn (Fig. 3e) zurückgeschwenkt, wobei er sich auf dem Warenbaum 51 abwälzt. Eine Tuchfaltvorrichtung 11 wird nach unten bewegt, bis das freie Ende 110 eines Schwerts an der Faltvorrichtung den Warenbaum 51 berührt und das Gewebe an dieser Stelle an den Warenbaum anpresst. Der Anwickelbaum wird nun weiter im Uhrzeigersinn mit Hilfe des Manipulators 71 geschwenkt, bis er das freie Ende 110 des Schwerts auf der dem Warenbaum 51 gegenüberliegenden Seite berührt (Fig. 3f) Dabei wird das freie Ende 510' des Gewebes und das über dem Anwickelbaum 70 liegende Gewebe so angehoben, dass das freie Ende 510' des Gewebes V-förmig zwischen Warenbaum 51, Schwert 110 und Anwickelbaum 70 liegt, und dass das Gewebe 510 im Bereich des freien Endes des Schwerts 110 tangential vom Anwickelbaum 70 auf den Warenbaum 51 übergeht (Fig. 3f'). Das Anwickeln ist auch möglich, wenn das freie Ende der Gewebebahn 510'' nur wenig über das freie Ende der Faltvorrichtung 11 hervorragt. Durch das Umfahren des Warenbaums 51 mittels des Anwickelbaums 70 wurde eine Gewebelage auf dem Warenbaum 51 angewickelt. Nun wird der Antrieb des Warenbaums 51 wieder eingeschaltet. Er dreht sich im Gegenuhrzeigersinn (Fig. 3f'), wobei Gewebe 510 vom Anwickelbaum-abgezogen und auf den Warenbaum 51 aufgewickelt wird. Bei dieser Bewegung wird das V-förmig um das Schwert 110 gelegte Ende 510' des Gewebes nach unten gezogen und sicher an den Umfang des Warenbaums 51 angedrückt, so dass die erste Gewebelage rutschfrei auf dem Warenbaum 51 aufliegt. Durch Weiterdrehen des Warenbaums werden mehrere Lagen des Gewebes 510 auf dem Warenbaum 51 aufgewickelt, während der Anwickelbaum 70 und die Faltvorrichtung 11 in der erwähnten Position bleiben (Fig. 3g, 3g'). Nachdem die Bewicklung des neuen Warenbaums 51 vorläufig abgeschlossen ist (Fig. 3h), wird die Tuchfaltvorrichtung 11 wieder in die Ausgangslage nach oben bewegt, während der Anwickelbaum 70 nach unten geschwenkt wird und ausser Kontakt mit dem Anwickelbaum 51 gerät.The sequence of figures 3a - 3h shows the winding process. After pressing the winding tree 70 onto the goods tree 51 (FIG. 3a), the goods tree 51 is briefly driven clockwise, whereby the winding tree in contact with it forms a cloth reserve towards the weaving machine. The tissue required for the formation of the cloth reserve is unwound from the full fabric tree 50 (FIG. 3b). After the winding tree 70 has reached a position above the goods tree 51 (FIG. 3c), a cutting device 10 is brought up to the right from the tissue, which is then severed at this point. The cutting device 10 is then moved back to its original position while the winding tree 70 is moved further to the left. The free end 510 'of the fabric then falls over the new fabric tree 51, whereupon it rotates clockwise until a certain free length of fabric 510' hangs from the fabric tree. The winding tree 70 is still in contact with the fabric tree 51, which is why it makes a counter-rotation (FIG. 3d). After the goods tree 51 has come to a standstill again, the winding tree 70 is pivoted back in a clockwise direction (FIG. 3e), whereby it rolls on the goods tree 51. A cloth folding device 11 is moved downward until the free end 110 of a sword on the folding device touches the fabric tree 51 and the fabric presses against the fabric tree at this point. The winding tree is now pivoted further clockwise with the aid of the manipulator 71 until it touches the free end 110 of the sword on the side opposite the fabric tree 51 (FIG. 3f). The free end 510 'of the fabric and that above the winding tree 70 lying fabric is raised so that the free end 510 'of the fabric lies in a V-shape between the fabric tree 51, the sword 110 and the winding tree 70, and that the fabric 510 is tangential in the region of the free end of the sword 110 The winding tree 70 merges with the goods tree 51 (FIG. 3f '). Wrapping is also possible if the free end of the fabric web 510 ″ protrudes only slightly over the free end of the folding device 11. By moving the goods tree 51 by means of the winding tree 70, a fabric layer was wound on the goods tree 51. Now the drive of the goods tree 51 is switched on again. It rotates counterclockwise (FIG. 3f '), with fabric 510 being pulled off the winding tree and wound onto the fabric tree 51. During this movement, the V-shaped end 510 'of the fabric placed around the sword 110 is pulled down and pressed securely against the circumference of the fabric tree 51, so that the first fabric layer rests on the fabric tree 51 without slipping. By turning the fabric tree further, several layers of the fabric 510 are wound onto the fabric tree 51, while the winding tree 70 and the folding device 11 remain in the position mentioned (FIGS. 3g, 3g '). After the winding of the new goods tree 51 has been provisionally completed (FIG. 3h), the cloth folding device 11 is moved upwards again into the starting position, while the winding tree 70 is pivoted downward and gets out of contact with the winding tree 51.

Der angewickelte Warenbaum 51 wird dann von den Greiferarmen 40a, 40b erfasst und nach unten in die Lagerstelle in der Webmaschine gebracht. Während des Absenkens des Warenbaums im Transportgerät 102 wird der lose gewordene Teil des Gewebeabschnitts zwischen Webmaschine und dem neuen Warenbaum in einer Zwischenposition des Warenbaums gestrafft, in dem er kurzzeitig im Gegenuhrzeigersinn angetrieben wird. Nach dem Einsetzen des Warenbaums in die Webmaschine fahren die Greifarme 40a, 40b im Transportgerät wieder nach oben, um den Anwickelbaum 70 zu erfassen und in die ursprüngliche Position 70' im unteren Teil des Transportgerätes gemäss Fig. 2 zu bringen. Dabei wird ein in der Folge zu beschreibender Manipulator eingesetzt.The wound goods tree 51 is then gripped by the gripper arms 40a, 40b and brought down into the storage location in the weaving machine. During the lowering of the goods tree in the transport device 102, the loosened part of the fabric section between the weaving machine and the new goods tree is tightened in an intermediate position of the goods tree, in which it is briefly driven counterclockwise. After the goods tree has been inserted into the weaving machine, the gripper arms 40a, 40b in the transport device move up again in order to grip the winding tree 70 and into the original position 70 'in the lower one Bring part of the transport device according to FIG. 2. A manipulator to be described below is used for this.

Fig. 4 zeigt Ausführungsbeispiele für das Verfahren des Anwickelns. Fig. 4 ist eine perspektivische Teilansicht von hinten auf den Seitenteil 20b des in Fig. 1 dargestellten Transportgerätes. In Fig. 4 sind nur einzelne Elemente des Seitenteils 20b und der Fahreinheit 1b dargestellt. Die Fahreinheit 1b wird u.a. über Rollen 154 auf dem Websaalboden abgestützt. Während des Anwickelvorgangs wird die sonst starre Verbindung zwischen der Fahreinheit 1b und dem Seitenteil 20b gelöst. Letzteres stützt sich in einer abgesenkten Position unter anderem über Füsse 23 auf dem Websaalboden ab. In Fig. 4 oben ist eine Axialverstellungseinrichtung 81 dargestellt, welche den Manipulator 71 für den Anwickelbaum und den Warenbaum 51 trägt. Am Seitenteil 20b sind Schwalbenschwanzführungen 200, an welchen eine Grundplatte 813 verschiebbar ist. Auf der Grundplatte 813 ist ein Schlitten 810 befestigt, der mit Hilfe eines Spindelantriebes 811 hin- und herbewegt werden kann, wenn eine im Seitenteil 20b eingeschraubte Gewindespindel 812 durch den Spindelantrieb verdreht wird. Unten an der Grundplatte 813 sitzt ein Gehäuse 801 der Ankoppelvorrichtung 80 für den Warenbaum 51. Der Warenbaum wird durch den Antrieb 803 verdreht, wenn er mit der Kupplung 804 gekoppelt worden ist, wobei das Ankoppeln durch Axialverstellung des Schlittens 810 bewirkt wird. Am Gehäuse 801 sitzt ein nicht drehbares Zahnrad 802. Vor diesem Zahnrad ist das Gehäuse 710 frei drehbar auf einem Fortsatz des Gehäuses 801 gelagert. Im Gehäuse 710 ist wiederum frei drehbar ein Zahnrad 717 gelagert, das mit dem Zahnrad 802 kämmt. Das Zahnrad 717 wird von der anderen Seite des Transportgerätes 102 aus über eine Welle 718 von einem Zahnriementrieb 719 angetrieben, dessen Antriebsrad konzentrisch mit dem Warenbaum 51 im Seitenteil 20a gelagert ist. Durch Drehen der Welle 718 wälzt sich das Zahnrad 717 auf dem fest angeordneten Zahnrad 802 ab, wodurch das Gehäuse 710 in eine Schwenkbewegung um die Achse des Warenbaums 51 versetzt wird. Eine Kurvenbahn 714 ist am Seitenteil 20b befestigt. Sie gelangt in einem bestimmten Winkelbereich des Gehäuses 710 während seiner Verdrehung in Kontakt mit der Rolle 713, die am Hebel 711 befestigt ist, der auf dem Zapfen 716 am Gehäuse 710 gelagert ist. Beim Auflaufen der Rolle 713 auf dem Kurvensegment 714 bewegt sie sich mit dem entsprechenden Teil des Hebels 711 in Richtung auf die Achse des Warenbaums 51, wobei die Druckfeder 712 mehr gespannt wird. Die Mulde 715 auf der anderen Seite des Hebels wird dabei nach aussen geschwenkt. In dieser Lage kann sie den von unten emporgehobenen Anwickelbaum 70 übernehmen. Beim Zurückschwenken des Hebels nach dem Einlegen des Anwickelbaums gerät die Mulde 715 unter einen Vorsprung 710' des Gehäuses 710, wodurch der eingelegte Zapfen des Anwickelbaumes verriegelt ist. Die Anwickeloperation ist bereits anhand der Figuren 3a - 3h beschrieben worden. Im unteren Teil des Transportgerätes ist ein Manipulator 72 dargestellt, der den Anwickelbaum aus seiner Ruheposition in der Mulde 720' in die Position der Mulde 720 bringt, in der der Anwickelbaum 70 durch die Greifer 40a, 40b emporgehoben wird. Das Anheben des Anwickelbaums von der Position 720' in die Position 720 mit Hilfe des Hebelarms 721 geschieht durch Einschalten des Spindelantriebes 724, an dem ein Hebelarm 723 angelenkt ist, der über eine Welle 722 mit dem Hebelarm 721 verbunden ist.4 shows exemplary embodiments for the method of winding. FIG. 4 is a partial perspective rear view of the side part 20b of the transport device shown in FIG. 1. 4 only individual elements of the side part 20b and the driving unit 1b are shown. The driving unit 1b is supported on the weaving floor, among other things, by means of rollers 154. During the winding-up process, the otherwise rigid connection between the driving unit 1b and the side part 20b is released. The latter is supported in a lowered position on feet 23 on the weaving room floor, among other things. 4 shows an axial adjustment device 81, which carries the manipulator 71 for the winding tree and the goods tree 51. On the side part 20b are dovetail guides 200, on which a base plate 813 can be moved. A carriage 810 is fastened on the base plate 813 and can be moved back and forth with the aid of a spindle drive 811 when a threaded spindle 812 screwed into the side part 20b is rotated by the spindle drive. At the bottom of the base plate 813 there is a housing 801 of the coupling device 80 for the merchandise tree 51. The merchandise tree is rotated by the drive 803 when it has been coupled to the coupling 804, the coupling being effected by axially adjusting the carriage 810. A non-rotatable gear 802 is seated on the housing 801. The housing 710 is mounted freely rotatably on an extension of the housing 801 in front of this gear. A gear 717, which meshes with the gear 802, is in turn freely rotatably mounted in the housing 710. The gear 717 is driven from the other side of the transport device 102 via a shaft 718 Toothed belt drive 719 driven, the drive wheel is mounted concentrically with the fabric tree 51 in the side part 20a. By rotating the shaft 718, the gear 717 rolls on the fixed gear 802, causing the housing 710 to pivot about the axis of the fabric tree 51. A cam track 714 is attached to the side part 20b. It comes in a certain angular range of the housing 710 during its rotation in contact with the roller 713, which is fastened to the lever 711, which is mounted on the pin 716 on the housing 710. When the roller 713 runs on the cam segment 714, it moves with the corresponding part of the lever 711 in the direction of the axis of the goods tree 51, the compression spring 712 being tensioned more. The trough 715 on the other side of the lever is pivoted outwards. In this position, it can take over the winding tree 70, which is raised from below. When the lever is pivoted back after inserting the winding tree, the trough 715 gets under a projection 710 ′ of the housing 710, as a result of which the inserted pin of the winding tree is locked. The winding operation has already been described with reference to FIGS. 3a-3h. In the lower part of the transport device, a manipulator 72 is shown, which brings the winding tree from its rest position in the trough 720 'into the position of the trough 720, in which the winding tree 70 is lifted up by the grippers 40a, 40b. The winding tree is raised from position 720 'to position 720 with the aid of lever arm 721 by switching on spindle drive 724, to which a lever arm 723 is articulated, which is connected to lever arm 721 via a shaft 722.

Der Manipulator 72 ist ebenso wie der Manipulator 71 auf beiden Seiten der Trageinheit angeordnet.The manipulator 72, like the manipulator 71, is arranged on both sides of the carrying unit.

Das sogenannte Schwert 110, welches beim Faltvorgang mit dem Gewebe 510 in Berührung steht, ist über einen Teil der Vorrichtung durchgehend ausgeführt und über den übrigen Teil der Vorrichtung in Segmente 110' gegliedert. Bei einer Breitenverstellung des Transportgerätes 102 mittels der Teleskopstangen 225 gemäss Fig. 1 wird die in Fig. 5 rechts gezeichnete Lagereinrichtung 21'' mit der dazugehörigen Parallelogrammführung gegenüber der übrigen Tuchfaltvorrichtung 11 in Längsrichtung verschoben. Die Segmente 110' des Schwerts rücken dabei näher zusammen bzw. bewegen sich voneinander weg, indem sie auf einer Schiene 111 über Rollen 112 gleiten. Der gleichmässige Abstand der einzelnen Segmente 110 wird durch ein elastisches Band 114 eingehalten, das an jedem Segment befestigt wird.5, the cloth folding device 11 is shown in detail. Bearing plates 21 'are fastened to the crossmember 21 of the transport device, on which the cloth folding device 11 is guided via a parallelogram guide 22. It is moved up and down by a spindle drive 23 which is articulated on a guide leg 22. The so-called sword 110, which is in contact with the tissue 510 during the folding process, is designed to be continuous over part of the device and is divided into segments 110 'over the remaining part of the device. When the transport device 102 is adjusted in width by means of the telescopic rods 225 according to FIG. 1, the bearing device 21 ″ shown on the right in FIG. 5, with the associated parallelogram guide, is displaced in the longitudinal direction with respect to the remaining cloth folding device 11. The segments 110 'of the sword move closer together or move away from each other by sliding on a rail 111 over rollers 112. The uniform spacing of the individual segments 110 is maintained by an elastic band 114 which is attached to each segment.

Die Schneideinrichtung 10 ist gemäss Fig. 6 ebenfalls an der Traverse 21a befestigt. Ein Antriebsmotor 101 treibt über einen Riemen 102' einen Antriebsriemen 102 an, der über die ganze Breite des Transportgerätes verläuft. Ueber Führungsrollen 104 ist ein Schneidschlitten 103 an der Traverse 21 geführt. Im oberen Teil des Schneidschlittens 103 ist der Riemen 102 durch Klemmrollen 105 festgehalten. Bei Bewegung des Riemens 102 läuft der Schneidschlitten entlang der Traverse 21. Hinter den Klemmrollen sind zwei Umlenkrollen 109 für den hinteren Teil des Riemens 102a sowie eine dazwischen angeordnete Antriebsrolle 106, welche über eine Welle mit der Schneidscheibe 107 drehfest verbunden ist. Ueber einen Teil des Umfangs der Schneidscheibe erstreckt sich eine Gewebeführung 108. Das Gewebe wird geschnitten, indem der Schneidschlitten entlang der Traverse 21a bewegt wird, während das Gewebe an der Einlauföffnung 108' zwischen Gewebeführung 108 und Schneidscheibe 107 in den Schneidschlitten 103 einläuft.6 is also attached to the crossbeam 21a. A drive motor 101 drives a drive belt 102 via a belt 102 ′, which runs across the entire width of the transport device. A cutting carriage 103 is guided on the crossmember 21 via guide rollers 104. The belt 102 is held in place by clamping rollers 105 in the upper part of the cutting carriage 103. When the belt 102 moves, the cutting carriage runs along the traverse 21. Behind the clamping rollers are two deflection rollers 109 for the rear part of the belt 102a and a drive roller 106 arranged in between, which is connected in a rotationally fixed manner to the cutting disk 107 via a shaft. About part of the A tissue guide 108 extends around the circumference of the cutting disk. The tissue is cut by moving the cutting carriage along the crossmember 21a, while the tissue runs into the cutting carriage 103 at the inlet opening 108 ′ between the tissue guide 108 and the cutting disk 107.

Im Längsschnitt durch den Anwickelbaum 70 in Fig. 7 sind im linken Teil zwei Rohre 701 und 701' ineinandergeschoben und durch Stifte 702 fest verbunden. Das Rohr 701' sitzt auf der rechten Seite in einem Rohr 707 in Gleitlagern 708. Das Rohr 701' weist teilweise Längsschlitze 701'' auf, durch welche einzelne Rohrsegmente 710 mit einem elastischen Band 709 verbunden sind. Die Verbindung wird durch Schraubbolzen 720 hergestellt. Auf diese Weise kann die Länge des Anwickelbaumes an die jeweilige Arbeitsbreite einer Webmaschine 500 bzw. des Transportgerätes 102 angepasst werden. Bei Betätigung der Verstellvorrichtung für die Breite im Transportgerät 102 mittels der Teleskopstangen 225 verschiebt sich das Rohr 701' gegenüber dem Rohr 707. Die Rohre 701 und 707 sowie die Rohrsegmente 710 tragen eine Oberflächenbeschichtung 706 aus weichem Kunststoff, mit dem sie sich zeitweise auf dem Warenbaum 51 abstützen. An den Bunden 703 auf beiden Seiten des Anwickelbaumes setzen die Greifarme 40a und 40b an. Der Anwickelbaum wird über Kugellager 704 in Supporten 705 abgestützt.In the longitudinal section through the winding tree 70 in FIG. 7, two tubes 701 and 701 ′ are pushed into one another in the left part and are firmly connected by pins 702. The tube 701 'sits on the right side in a tube 707 in slide bearings 708. The tube 701' has in part longitudinal slots 701 '' through which individual tube segments 710 are connected with an elastic band 709. The connection is made by 720 bolts. In this way, the length of the winding tree can be adapted to the respective working width of a weaving machine 500 or of the transport device 102. When the adjustment device for the width in the transport device 102 is actuated by means of the telescopic rods 225, the tube 701 'moves relative to the tube 707. The tubes 701 and 707 as well as the tube segments 710 have a surface coating 706 made of soft plastic, with which they are temporarily on the goods tree Support 51. The gripping arms 40a and 40b attach to the bundles 703 on both sides of the winding tree. The winding tree is supported by ball bearings 704 in supports 705.
