Description

Die Erfindung betrifft ein Transportgerät für eine Weberei gemäss Oberbegriff von Anspruch 1. Bei den meisten im Einsatz befindlichen Webmaschinen werden die Kettfäden auf sogenannte Kettbäume aufgewickelt zum Abweben an eine Webmaschine gebracht, wobei die Kettbäume beachtliche Dimensionen und eine grosse Masse aufweisen können. Auf der dem Kettbaum gegenüberliegenden Seite einer Webmaschine wird das gewebte Tuch auf einen Warenbaum aufgewickelt, der von Zeit zu Zeit aus der Webmaschine entnommen wird, wenn das aufgewickelte Gewebe seinen höchstzulässigen Durchmesser erreicht hat. Während des Abwebens eines Kettbaumes muss der Warenbaum in der Regel mehrmals gewechselt werden, wobei die Webmaschine möglichst nicht ausser Betrieb gesetzt werden soll.The invention relates to a transport device for a weaving mill according to the preamble of claim 1. In most weaving machines in use, the warp threads are wound onto so-called warp beams for weaving on a weaving machine, whereby the warp beams can have considerable dimensions and a large mass. On the side of a weaving machine opposite the warp beam, the woven cloth is wound onto a fabric tree, which is removed from the weaving machine from time to time when the wound fabric has reached its maximum permissible diameter. When weaving a warp beam, the fabric beam usually has to be changed several times, whereby the weaving machine should preferably not be taken out of operation.

In Webereien sind angetriebene Transportgeräte für Kett- und Warenbäume bekannt, welche vom Personal durch die Weberei gelenkt werden und zwischen den Webmaschinen in eine zum Wechseln des Kett- bzw. Warenbaums geeignete Position gebracht werden müssen. Da der Abstand zwischen den Webmaschinen in einer Weberei normalerweise sehr beschränkt ist, erfordert das Lenken der Transportgeräte zwischen den Webmaschinen und das Positionieren zum Baumwechsel viel Kraft und Geschick vom Webereipersonal.Driven transport devices for warp and fabric trees are known in weaving mills, which are steered by the staff through the weaving mill and must be brought between the weaving machines into a position suitable for changing the warp or fabric tree. Since the distance between the weaving machines in a weaving mill is usually very limited, the transport equipment must be steered between the weaving machines and the positioning to change the tree a lot of strength and skill from the weaving staff.

Aus der DE-A-2 417 476 ist ein Transportgerät bekannt, das für eine Zwei-Mann-Bedienung vorgesehen ist und das in zwei Fahreinheiten und eine Trageinheit gegliedert ist. Bei einem derartigen Transportgerät kann die Trageinheit gegenüber den Fahreinheiten einerseits verschiebbar angeordnet und andererseits starr koppelbar sein. Die Fahreinheiten können in Fahrtrichtung bzw. Längsrichtung des Gerätes vor und hinter der Trageinheit angeordnet sein. Die Trageinheit kann an beiden den Fahreinheiten zugewandten Seiten je einen Gelenkarm aufweisen, der jeweils mit einem weiteren Gelenkarm einer Fahreinheit über ein Gelenk verbunden ist, wodurch die Trageinheit gegenüber den Fahreinheiten in allen horizontalen Richtungen verschiebbar ist. Zwischen Trageinheit und den Fahreinheiten kann eine Hubeinrichtung angeordnet sein, mit der die Trageinheit gegenüber den Fahreinheiten anhebbar und absenkbar ist.From DE-A-2 417 476 a transport device is known which is intended for two-man operation and which is divided into two driving units and a carrying unit. With a transport device of this type, the carrying unit can on the one hand be arranged displaceably relative to the driving units and on the other hand can be rigidly coupled. The driving units can be arranged in front of and behind the carrying unit in the direction of travel or longitudinal direction of the device. The carrying unit can have an articulated arm on both sides facing the driving units, each of which is connected to a further articulated arm of a driving unit via a joint, as a result of which the carrying unit can be displaced in all horizontal directions with respect to the driving units. A lifting device can be arranged between the carrying unit and the driving units, with which the carrying unit can be raised and lowered relative to the driving units.

Es ist Aufgabe der vorliegenden Erfindung, ein Transportgerät für eine Weberei zu schaffen, mit dem ohne Personaleinsatz und bei laufender Webmaschine der Wechsel des Kettbaums bzw. Warenbaums ermöglicht wird. Das Gerät soll auch unter beengten Platzverhältnissen seine Transportaufgaben rasch und sicher durchführen.It is an object of the present invention to provide a transport device for a weaving mill, with which the warp beam or goods beam can be changed without the use of personnel and with the weaving machine running. The device should be able to carry out its transport tasks quickly and safely even in tight spaces.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.This object is achieved according to the invention by the features of the characterizing part of claim 1.

Während des Wechselvorganges beispielsweise des Warenbaums an einer Webmaschine kann die Trageinheit unabhängig von den Fahreinheiten innerhalb eines gewissen Bewegungsraumes auf den Boden der Weberei abgesenkt werden, nachdem sie eine genaue Position bezüglich der Webmaschine mittels sogenannter Andockelemente vorgenommen hat. Die Andockelemente sind einerseits an ausfahrbaren Armen der Trageinheit befestigt und befinden sich andererseits in bestimmten Positionen vor der Webmaschine. Durch Koppeln der Andockelemente der Trageinheit mit jenen der Webmaschine zugeordneten Andockelementen nimmt die Trageinheit eine exakte Position gegenüber der Webmaschine ein, wodurch eine ortsgenaue Zusammenarbeit zwischen Funktionsorganen der Trageinheit und der Webmaschine ermöglicht wird.During the changing process, for example of the goods tree on a weaving machine, the carrying unit can be lowered to the floor of the weaving mill within a certain range of motion, independently of the driving units after having made a precise position with respect to the weaving machine using so-called docking elements. The docking elements are attached on the one hand to extendable arms of the carrying unit and on the other hand are located in certain positions in front of the weaving machine. By coupling the docking elements of the carrying unit with those docking elements assigned to the weaving machine, the carrying unit assumes an exact position in relation to the weaving machine, which enables a precise cooperation between functional elements of the carrying unit and the weaving machine.

Das Transportgerät kann selbständig zu einer Webmaschine fahren, bei der beispielsweise der Warenbaum gewechselt werden muss. Eine genaue Lage des Transportgerätes gegenüber der Webmaschine muss beim Heranfahren an diese nicht angestrebt werden, so dass für die Lenkung des Transportgerätes eine einfache Spurführung, beispielsweise durch einen im Boden verlegten Draht, der berührungslos abgetastet wird, genügt. Die Verstellbarkeit der Trageinheit gegenüber den Fahreinheiten ermöglicht ein genaues Ausrichten der Trageinheit an der Webmaschine ohne Bewegung der Fahreinheiten und ohne Kraftanstrengung.The transport device can independently drive to a weaving machine, for example, in which the goods tree has to be changed. An exact position of the transport device in relation to the weaving machine does not have to be aimed for when approaching it, so that simple guidance, for example by a wire laid in the ground, which is scanned without contact, is sufficient for steering the transport device. The adjustability of the carrying unit in relation to the driving units enables the carrying unit to be precisely aligned on the weaving machine without the driving units moving and without exertion of force.

Die Funktionsorgane der Trageinheit bestehen aus Greifelementen, Lagerelementen und Hilfsantrieben, mit welchen der Kett- bzw. Warenbaumwechsel an der Webmaschine durchgeführt wird. Während des Wechselvorganges ruht die Trageinheit auf dem Websaalboden bzw. auf Andockelementen, die der Webmaschine zugeordnet sind. Die Fahreinheiten sind dabei von der Trageinheit entlastet. Nach Abschluss des Wechselvorganges der Kett- bzw. Warenbäume an der Webmaschine wird die Trageinheit durch Kupplungselemente wieder starr mit den Fahreinheiten verbunden, so dass die Last des gesamten Transportgerätes über Räder der Fahreinheiten auf dem Websaalboden abgestützt sein können.The functional elements of the support unit consist of gripping elements, bearing elements and auxiliary drives, with which the warp or fabric change is carried out on the weaving machine. During the changing process, the carrying unit rests on the weaving room floor or on docking elements which are assigned to the weaving machine. The driving units are relieved of the load on the carrying unit. After the changing of the warp or fabric trees on the weaving machine, the carrying unit becomes rigid again through coupling elements connected to the travel units, so that the load of the entire transport device can be supported on the weaving room floor via wheels of the travel units.

In Fig. 1 ist zum Teil schematisch der Aufbau des Transportgerätes dargestellt. Es ist in Fahreinheiten 1a bzw. 1b und eine dazwischen angeordnete Trageinheit 2 gegliedert. Die Fahreinheiten enthalten je einen Fahrantrieb sowie Stützrollen. Die Trageinheit ist mit einem vollen Warenbaum 50, einem leeren Warenbaum 51, einem Anwickelbaum 70 gezeichnet, welche durch Greifarme 40a, 40b manipuliert werden können. Weiterhin sind ein sogenanntes Schwert 11 einer Tuchfaltvorrichtung und eine Schneidvorrichtung 10 angedeutet. Eine Traverse 21 verbindet den rechten Seitenteil 20a mit dem linken Seitenteil 20b, wobei die Traverse 21 gegenüber dem Seitenteil 20b verschiebbar ist.In Fig. 1, the structure of the transport device is partially shown schematically. It is divided into driving units 1a and 1b and a support unit 2 arranged between them. The travel units each contain a travel drive and support rollers. The carrying unit is drawn with a full goods tree 50, an empty goods tree 51, a winding tree 70, which can be manipulated by gripping arms 40a, 40b. Furthermore, a so-called sword 11 of a cloth folding device and a cutting device 10 are indicated. 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.

In Fig. 1a ist das Transportgerät 102 zwischen zwei Webmaschinen 500a, 500b gezeigt. In den Webmaschinen 500 wird das Garn von einem Kettbaum 501 über Spann- und Umlenkstangen 502 zur Weblade 503 geführt, wo der Schusseintrag erfolgt. Ueber einen Warenabzug 504 und Umlenkstangen 505 wird das Gewebe einem Warenbaum 50 zugeführt. Die erwähnten Teile der Webmaschine sind zwischen Wangen 506 gelagert, welche durch Rohrtraversen 507a, 507b und Winkeltraversen 508a, 508b zusammengehalten sind. Die Wangen 506 sind auf Fussschienen 509 abgestützt. Das Gewebe wird dem Pfeil 510 folgend dem Warenbaum 50 zugeführt und auf diesem aufgewickelt, bis ein höchstzulässiger Durchmesser des Tuchwickels auf dem Warenbaum 50 erreicht wird. Dies kann durch einen Sensor innerhalb der Webmaschine 500 angezeigt werden. Eine logistische Steuereinrichtung der Weberei beordert dann das Transportgerät 102 zu der betreffenden Webmaschine. Der Warenbaum 50 wird durch die Greifer 40a, 40b aus der Webmaschine 500a herausgenommen und in eine Halterung in das Transportgerät 102 gelegt. Anschliessend wird der Anwickelbaum 70 aus der unteren ausgezogenen Position im Transportgerät zum neuen noch leeren Warenbaum 51 herangeführt, wobei sich das nicht abgeschnittene Gewebe zwischen dem Warenbaum 50 im Transportgerät und der Umlenkstange 505 um den Anwickelbaum 70 legt. Dieser wird dann durch eine nicht dargestellte Vorrichtung entgegen dem Uhrzeigersinn um den neuen Warenbaum 51 gerollt. In der in Fig. 1a gezeichneten Position 70' des Anwickelbaumes wird das Gewebe durch eine Schneidvorrichtung 10 geschnitten. Das freie Ende des Gewebes oberhalb der Schneidvorrichtung 10 wird in einer weiteren Abwälzung des Anwickelbaumes 70' auf dem Warenbaum 51 vollständig auf dem Warenbaum 51 aufgewickelt. Das Schwert 11 einer Tuchfaltvorrichtung wird dabei so weit abgesenkt, bis es tangential am Warenbaum 51 aufliegt und so das Gewebe während des Anwickelns am Warenbaum 51 führt.The transport device 102 between two weaving machines 500a, 500b is shown in FIG. 1a. In the weaving machines 500, the yarn is guided from a warp beam 501 via tensioning and deflecting rods 502 to the sley 503, where the weft insertion takes place. The fabric is fed to a fabric tree 50 via a fabric take-off 504 and deflecting rods 505. The parts of the weaving machine mentioned are mounted between cheeks 506, which are held together by tubular cross members 507a, 507b and angular cross members 508a, 508b. The cheeks 506 are supported on foot rails 509. The fabric becomes the fabric tree 50 following the arrow 510 fed and wound on this until a maximum permissible diameter of the cloth wrap on the fabric tree 50 is reached. This can be indicated by a sensor within the weaving machine 500. A logistic control device of the weaving mill then orders the transport device 102 to the relevant weaving machine. The goods tree 50 is removed from the weaving machine 500a by the grippers 40a, 40b and placed in a holder in the transport device 102. The winding tree 70 is then moved from the lower extended position in the transport device to the new, yet empty goods tree 51, the non-cut fabric lying between the goods tree 50 in the transport device and the deflecting rod 505 around the winding tree 70. This is then rolled counterclockwise around the new goods tree 51 by a device, not shown. In the position 70 ′ of the winding tree shown in FIG. 1a, the tissue is cut by a cutting device 10. The free end of the fabric above the cutting device 10 is completely wound onto the fabric tree 51 in a further rolling of the winding tree 70 'on the fabric tree 51. The sword 11 of a cloth folding device is lowered until it lies tangentially on the fabric tree 51 and thus guides the fabric on the fabric tree 51 during winding.

Fig. 2 beinhaltet Teile des Transportgerätes 102, insbesondere einen Fahrantrieb 15 in der Fahreinheit 1b, der eine einzige von einem Fahrmotor 153 angetriebene Rolle 150 enthält. Eine Lenkvorrichtung 16 für die Antriebsrolle 150 umfasst einen Lenkmotor 161, der über einen Zahnriemen 162 mit der Antriebsrolle 150 verbunden ist. Der Lenkmotor 161 wird aufgrund von Informationen einer Abtasteinheit 151 gesteuert, welche eine Fahrspur 152 im Websaalboden verfolgt. Wenn die Abtasteinheit 151 von einer zur Fahrspur 152 symmetrischen Lage abweicht, wird die Antriebsrolle 150 so gesteuert, dass die gewünschte Lage der Abtasteinheit 151 über der Fahrspur 152 innerhalb gewisser Toleranzen erreicht wird. Neben der Antriebsrolle 150 in einer Fahreinheit wird das Transportgerät durch Stützrollen 154 getragen. Beim linken Seitenteil 20a der Trageinheit befindet sich eine Breitenverstellvorrichtung für die Trageinheit 2, in welcher die Seitenteile 20a, 20b sich näher gebracht bzw. voneinander entfernt werden können. Ein Motor 220 kann über Riementriebe 221, 222, 223 Teleskoprohre 224, 225, 226 in Drehung versetzen, welche an ihrem jeweils rechten Ende über Kugelbüchsen auf Teleskopspindeln 224', 225', 226' sitzen. Durch das Verdrehen der Teleskopstangen relativ zu den Teleskopspindeln werden die Teile axial zueinander verschoben. Dadurch ist das Transportgerät 102 für verschieden breite Webmaschinen bzw. Warenbäume einsetzbar.2 contains parts of the transport device 102, in particular a travel drive 15 in the driving unit 1b, which contains a single roller 150 driven by a travel motor 153. A steering device 16 for the drive roller 150 comprises a steering motor 161 which is connected to the drive roller 150 via a toothed belt 162. The steering motor 161 is controlled on the basis of information from a scanning unit 151 which tracks a lane 152 in the floor of the weaving room. If the scanning unit 151 of a position deviating symmetrically to the lane 152, the drive roller 150 is controlled so that the desired position of the scanning unit 151 above the lane 152 is achieved within certain tolerances. In addition to the drive roller 150 in a drive unit, the transport device is carried by support rollers 154. On the left side part 20a of the carrying unit there is a width adjustment device for the carrying unit 2, in which the side parts 20a, 20b can be brought closer to or removed from one another. A motor 220 can set telescopic tubes 224, 225, 226 in rotation via belt drives 221, 222, 223, which are seated at their respective right ends via ball bushings on telescopic spindles 224 ', 225', 226 '. By rotating the telescopic rods relative to the telescopic spindles, the parts are moved axially to each other. As a result, the transport device 102 can be used for weaving machines or goods trees of different widths.

In Fig. 3 sind der Antrieb des Greifarms 40b und umliegende Teile dargestellt. Der Greifarm 40b ist um die Achse 41 drehbar durch einen Motor 402 angetrieben. Ein Motor 403 sorgt über die Verzahnung 403' für eine Axialverstellung des Greifarmes in kleinem Rahmen. Die Vertikalbewegung des ganzen Greifarmes 40b wird durch einen Motor 401 und eine mittels einer Spiralfeder 401' abgedeckte Spindel vertikal verstellt. Innerhalb eines Greifarmes 40b befindet sich ein Mechanismus zum Oeffnen und Schliessen des Greifarms. Der Greifarm 40b ist in der Stellung gezeichnet, in der er den Warenbaum auf Zapfen 52, 52' ablegt. Diese Lagerung des Warenbaums 50 ist in Richtung der Achse 41 mit dem Greifarm 40b verstellbar, wenn die Rollen 53' sich im Bereich der Führungsstange 53 bewegen. In Fig. 3 ist die Verstellbarkeit der Trageinheit 2 bzw. des Seitenteils 20b gegenüber der Fahreinheit 1b zu sehen. An der Fahreinheit 1b ist eine Gelenklasche 1' angelenkt, auf welche sich eine zweite Gelenklasche 2' abstützen kann. Die Gelenklasche 2' ist über eine Gelenkstange 202 mit dem Seitenteil 20b verbunden. Die Gelenkstange 202 dient auch als Kolben, gegen den Zylinderteil 201 vertikal verschoben werden kann. Damit kann die ganze Trageinheit 2 horizontal und vertikal gegenüber der Fahreinheit 1b bewegt werden. Wenn die Trageinheit wie in Fig. 3 dargestellt gegenüber der Fahreinheit 1b abgesenkt ist, ruht sie teilweise auf einem Tellerfuss 23. Der Greifarm 40b sitzt zusammen mit den Antrieben 402 und 403 an einem Schlitten 404', der durch eine Gleitführung 404 vertikal geführt wird und mittels des Antriebsmotors 401 vertikal verstellt werden kann. Auf der anderen Seite der Trageinheit 2 befindet sich spiegelbildlich dieselbe Anordnung wie in Fig. 3 dargestellt.In Fig. 3 the drive of the gripping arm 40b and surrounding parts are shown. The gripping arm 40b is driven to rotate about the axis 41 by a motor 402. A motor 403 provides an axial adjustment of the gripping arm in a small frame via the toothing 403 '. The vertical movement of the entire gripper arm 40b is vertically adjusted by a motor 401 and a spindle covered by a spiral spring 401 '. A mechanism for opening and closing the gripper arm is located within a gripper arm 40b. The gripping arm 40b is drawn in the position in which it places the goods tree on pins 52, 52 '. This storage of the goods tree 50 is adjustable in the direction of the axis 41 with the gripping arm 40b when the rollers 53 'move in the region of the guide rod 53. In Fig. 3 is the adjustability of the support unit 2 or the side part 20b with respect to the driving unit 1b to see. An articulated bracket 1 'is articulated on the driving unit 1b, on which a second articulated bracket 2' can be supported. The link plate 2 'is connected to the side part 20b via a link rod 202. The joint rod 202 also serves as a piston against which the cylinder part 201 can be displaced vertically. The entire carrying unit 2 can thus be moved horizontally and vertically with respect to the driving unit 1b. If, as shown in FIG. 3, the carrying unit is lowered relative to the driving unit 1b, it partially rests on a plate foot 23. The gripping arm 40b sits together with the drives 402 and 403 on a carriage 404 'which is guided vertically by a sliding guide 404 and can be adjusted vertically by means of the drive motor 401. On the other side of the support unit 2, the same arrangement as shown in FIG. 3 is mirrored.

Fig. 4 zeigt die Vorrichtung zum Heben und Senken der Trageinheit gegenüber der Fahreinheit sowie die Positioniereinheit für die Trageinheit an einer Webmaschine. Ueber einen Antriebsmotor 281 und einen Riementrieb 282 kann eine Welle 283 angetrieben werden, mit der eine Spindel 283' einen Kolben 284' innerhalb eines Zylinder 284, der mit Hydrauliköl gefüllt ist, hin- und her-  schiebt. Das verdrängte Hydrauliköl gelangt über eine Leitung 285 in den Zylinder 201, wodurch dieser gegenüber dem Kolben 202 und somit die ganze Trageinheit 2 gegenüber der Fahreinheit 1b vertikal angehoben wird. In Fig. 4 sind weiterhin Bolzen 26' und 27' zu sehen, die im Seitenteil 20b bzw. im Zylinderteil 201 sitzen und bei Vertikalbewegung der Trageinheit 2 gegenüber der Fahreinheit 1b sich innerhalb der Kulissen 26 und 27 an der Fahreinheit 1b bewegen. Während die Kulissen 26 und 27 im oberen Teil die Bolzen 26' bzw. 27' exakt führen, geben sie ihnen in ihrem unteren Teil genügend Spielraum, damit sich die Tregeinheit 2 gegenüber der Fahreinheit 1b während des Vorgangs der Positionierung bewegen kann. Die Beweglichkeit der Trageinheit 2 gegenüber der Fahreinheit 1b ist wie oben beschrieben durch die gelenkige Lagerung 1′, 2′ ermöglicht. Zum Positionieren der Trageinheit gegenüber einer Webmaschine werden die Fahreinheiten nach dem Heranfahren des Transportgerätes 102 an eine Webmaschine 500 stillgesetzt, worauf Stützen 30a und 30b aus dem Fuss des Seitenteils 20a bzw. 20b mit Hilfe des Antriebes 31 ausgefahren werden. Am Ende der Stützen 30a bzw. 30b sitzt ein Prismenfuss 25 bzw. ein Trichterfuss 24, welche über ein Prisma 25′ bzw. einen Kegel 24′ auf dem Websaalboden bewegt werden. Nach dem Ausfahren der Stützen 30a und 30b wird die Trageinheit 2 gegenüber den Fahreinheiten 1a und 1b wie beschrieben abgesenkt, bis die Füsse 24 und 25 mit dem Kegel 24′ und dem Prisma 25′ in Berührung kommen. Das exakte Positionieren der Trageinheit 2 vor einer Webmaschine 500a wird durch Zentrieren des Trichterfusses 24 auf dem Kegel 24′ bzw. des Prismenfusses 25 auf dem Prisma 25′ erreicht.Fig. 4 shows the device for lifting and lowering the support unit with respect to the driving unit and the positioning unit for the support unit on a weaving machine. A shaft 283 can be driven via a drive motor 281 and a belt drive 282, with which a spindle 283 'pushes a piston 284' back and forth within a cylinder 284 which is filled with hydraulic oil. The displaced hydraulic oil reaches the cylinder 201 via a line 285, as a result of which the cylinder 201 is lifted vertically relative to the piston 202 and thus the entire support unit 2 relative to the driving unit 1b. 4, bolts 26 'and 27' can also be seen, which are seated in the side part 20b and in the cylinder part 201 and, when the support unit 2 moves vertically relative to the driving unit 1b, move on the driving unit 1b within the scenes 26 and 27. While the scenes 26 and 27 guide the bolts 26 'and 27' exactly in the upper part, they give them enough leeway in their lower part The treg unit 2 can move relative to the driving unit 1b during the positioning process. The mobility of the support unit 2 relative to the driving unit 1b is made possible as described above by the articulated mounting 1 ', 2'. To position the support unit in relation to a weaving machine, the driving units are stopped after the transport device 102 approaches a weaving machine 500, whereupon supports 30a and 30b are moved out of the foot of the side part 20a and 20b with the aid of the drive 31. At the end of the supports 30a and 30b there is a prism base 25 and a funnel base 24, which are moved via a prism 25 'or a cone 24' on the weaving room floor. After extending the supports 30a and 30b, the support unit 2 is lowered relative to the driving units 1a and 1b as described until the feet 24 and 25 come into contact with the cone 24 'and the prism 25'. The exact positioning of the support unit 2 in front of a weaving machine 500a is achieved by centering the funnel foot 24 on the cone 24 'or the prism foot 25 on the prism 25'.

Beim Uebernehmen des vollen Warenbaums 50 aus der Webmaschine 500a erhöhen die ausgefahrenen Stützen 30a und 30b die Standsicherheit des Transportgerätes.When the full goods tree 50 is taken over from the weaving machine 500a, the extended supports 30a and 30b increase the stability of the transport device.
