Description

Die Erfindung betrifft ein Betriebsverfahren für den Warenbaumwechsel mittels eines Transportgerätes in einer Webmaschine. Transportgeräte dieser Art werden eingesetzt, damit voll bewickelte Warenbäume rasch und ohne Anstrengungen für das Webereipersonal zur Weiterverarbeitung gebracht werden können.The invention relates to an operating method for the change of fabric by means of a transport device in a weaving machine. Transport devices of this type are used so that fully wound goods trees can be brought to further processing quickly and without effort for the weaving staff.

In JP-A-60 171956 US-A-4606381) wird ein Transportwagen mit Greifarmen zur Uebernahme des Warenbaums aus einer Webmaschine beschrieben. Nachdem der volle Warenbaum im Transportwagen positioniert ist, wird vom Transportwagen her ein neuer Warenbaum in die Webmaschine eingesetzt. Der neue Warenbaum muss dann mit einer Hilfsvorrichtung in der Webmaschine angewickelt werden. Zum Anwickeln des neuen Warenbaumes ist praktisch nur die dem Webergang zugewandte Seite des Warenbaums zugänglich. Da die Platzverhältnisse in der Umgebung des Warenbaums im unteren Bereich einer Webmaschine normalerweise sehr beengt sind, muss der Transportwagen genau an die Webmaschine angepasst sein.JP-A-60 171956 US-A-4606381) describes a transport trolley with gripper arms for taking over the goods tree from a weaving machine. After the full goods tree is positioned in the trolley, a new goods tree is inserted into the weaving machine from the trolley. The new goods tree must then be wound up with an auxiliary device in the weaving machine. To wind up the new merchandise tree, practically only the side of the merchandise tree facing the weaving aisle is accessible. Since the space around the goods tree in the lower area of a weaving machine is usually very cramped, the trolley must be precisely adapted to the weaving machine.

Es ist Aufgabe der vorliegenden Erfindung, ein Transportgerät für Warenbäume zu schaffen, das unabhängig von einer bestimmten Bauart der Webmaschinen eingesetzt werden kann. Diese Aufgabe wird erfindungsgemäss durch ein Betriebsverfahren für ein Transportgerät gelöst, welches folgende Schritte umfasst:

  • Entnahme des vollen Warenbaums aus der Webmaschine und Lagerung im Transportgerät mittels Greifarmen ohne Abschneiden des Gewebes,
  • Bildung einer Gewebeschlaufe mit einem Anwickelbaum, welcher zwischen Warenbaum und der Webmaschine quer zur Gewebebahn bewegt wird, wobei das Gewebe erfasst und teilweise vom Warenbaum abgewickelt wird, während sich der Anwickelbaum vom vollen Warenbaum 50 weg in Richtung auf einen leeren Warenbaum bewegt und die Gewebeschlaufe um den neuen Warenbaum legt,
  • Abschneiden des Gewebes zwischen neuem Warenbaum 51 und vollem Warenbaum 50,
  • Umwickeln des neuen Warenbaumes mit dem einen freien Ende des auf dem Anwickelbaum liegenden Teils der Gewebeschlaufe mit Hilfe des Anwickelbaums und Anwickeln des neuen Warenbaums,
  • Rückführung des neuen angewickelten Warenbaums in die Webmaschine unter gleichzeitigem Aufwickeln des Gewebes.
It is an object of the present invention to provide a transport device for goods trees that is independent of a certain type of weaving machine can be used. According to the invention, this object is achieved by an operating method for a transport device, which comprises the following steps:
  • Removal of the full goods tree from the weaving machine and storage in the transport device by means of gripper arms without cutting off the fabric,
  • Forming a fabric loop with a wrapping tree which is moved between the fabric tree and the weaving machine transversely to the fabric web, the fabric being gripped and partially unwound from the fabric tree as the wrapping tree moves away from the full fabric tree 50 towards an empty fabric tree and the fabric loop around puts the new goods tree,
  • Cutting the fabric between the new goods tree 51 and full goods tree 50,
  • Wrapping the new goods tree with one free end of the part of the fabric loop lying on the winding tree with the help of the winding tree and winding the new goods tree,
  • Return of the new wrapped fabric to the weaving machine while winding up the fabric.

Das Transportgerät zur Durchführung des Verfahrens muss mit einer Aufnahmevorrichtung für den vollen Warenbaum, mindestens einem Lager für den neuen Warenbaum und einem Anwickelbaum ausgestattet sein, weiterhin mit einer Schere zum Trennen des Gewebes. Ein Gerät nach dem beschriebenen Verfahren kann ohne weiteres für verschiedene Webmaschinentypen eingesetzt werden, wenn genügend Freiraum für die Greifarme des Gerätes bei den Lagerstellen des Warenbaums in der Webmaschine vorhanden ist. Durch das Anwickeln des neuen Warenbaumes im Transportgerät ist dieser praktisch von allen Seiten zugänglich, wodurch der Anwickelvorgang sicher abläuft und ein Rutschen des angewickelten Gewebes vermieden wird.The transport device for carrying out the method must be equipped with a receiving device for the full goods tree, at least one warehouse for the new goods tree and a winding tree, and also with scissors for separating the fabric. A device according to the described method can easily be used for different types of weaving machines if there is sufficient space for the gripping arms of the device at the storage locations of the goods tree in the weaving machine. By winding the new goods tree in the transport device, it is practically accessible from all sides, whereby the winding process runs safely and slippage of the wound fabric is avoided.

Die erwähnten Elemente der Webmaschine sind zwischen Wangen 506 gelagert, welche durch Rohrtraversen 507b und Winkeltraversen 508b zusammengehalten sind. Die Wangen 506 sind auf Fussschienen 509 abgestützt. Das Gewebe wird bis zu einem höchstzulässigen Durchmesser des Tuchwickels auf dem Warenbaum 50 aufgewickelt. Dies kann durch einen Sensor innerhalb der Webmaschine 500a angezeigt werden. Eine logistische Steuereinrichtung der Weberei beordert dann das Transportgerät 102 zur betreffenden Webmaschine 500a.1, the transport device 102 is shown in a view in the longitudinal direction next to a weaving machine 500a. In the loom 500a, warp threads are fed to a sley 503, where the weft insertion takes place. The fabric 510 is directed to a goods tree 50 via a material train 504 and deflecting rods 505 and wound 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 wrap. This can be indicated by a sensor within the weaving machine 500a. A logistic control device of the weaving mill then orders the transport device 102 to the relevant weaving machine 500a.

Im folgenden wird das Verfahren des Warenbaumwechsels beschrieben.The procedure for changing the merchandise tree is described below.

Fig. 1: Der Greifarm 40a bewegt sich gemäss Pfeil 40a′ senkrecht nach unten. Er schwenkt dabei um einen Drehpunkt an seinem oberen Ende nach links und umfasst den Lagerzapfen 55 des Warenbaums 50, wehrend seine Schenkel 42,43 sich in eine Offenstellung bewegen.Fig. 1: The gripper arm 40a moves according to arrow 40a 'vertically downwards. He swings around one Pivotal point at its upper end to the left and encompasses the bearing journal 55 of the merchandise tree 50 while its legs 42, 43 move into an open position.

Fig. 2: Der Greifarm 40a hat den Lagerzapfen 55 umfasst und seine Schenkel 42 und 43 geschlossen. Parallel zum Greifarm 40a wird der Greifarm 40b auf der anderen Seite des Warenbaums bewegt. Anschliessend heben die Greifarme 40a,40b in einer vertikalbewegung und gleichzeitigen Schwenkbewegung nach rechts den Warenbaum 50 aus der Webmaschine und setzen ihn in der strichpunktierten Position 50′ in das Transportgerät ein.Fig. 2: The gripper arm 40a has the bearing pin 55 and closed its legs 42 and 43. Parallel to the gripping arm 40a, the gripping arm 40b is moved on the other side of the goods tree. Then the gripper arms 40a, 40b in a vertical movement and simultaneous pivoting movement to the right, the fabric tree 50 from the weaving machine and insert it in the dot-dash position 50 'in the transport device.

Fig. 3: Ein Manipulator 72 für den Anwickelbaum 70 hebt den Anwickelbaum 70 in einer Schwenkbewegung nach links so weit an, dass dieser von den Greifarmen 40a,40b übernommen werden kann.3: A manipulator 72 for the winding tree 70 lifts the winding tree 70 in a pivoting movement to the left to such an extent that it can be taken over by the gripping arms 40a, 40b.

Fig. 4: Die Greifarme 40a,40b fahren im Transportgerät 102 vertikal nach oben und führen eine Schwenkbewegung nach rechts aus, wobei die Schlaufenbildung des Gewebes 510 beginnt. Zur Bildung der Schlaufe muss Gewebe vom Warenbaum 50 abgewickelt werden, der sich in Richtung des eingezeichneten Pfeils dreht. Gleichzeitig dreht sich auch der Anwickelbaum 70 in Pfeilrichtung. Während des Warenbaumwechsels muss die Webmaschine nicht stillgesetzt werden, so dass laufend neues Gewebe in Richtung des Pfeils 510′ von der Webmaschine 500a abgeführt wird.4: The gripping arms 40a, 40b move vertically upwards in the transport device 102 and execute a swiveling movement to the right, the loop formation of the fabric 510 starting. To form the loop, fabric must be unwound from the fabric tree 50, which rotates in the direction of the arrow shown. At the same time, the winding tree 70 also rotates in the direction of the arrow. The weaving machine does not have to be stopped during the change of the fabric tree, so that new weave is continuously removed from the weaving machine 500a in the direction of the arrow 510 ′.

Fig. 5: Die Greifarme 40a,40b setzen den Anwickelbaum 70 in eine Zwischenlagerstelle ein und geben ihn frei.Fig. 5: The gripping arms 40a, 40b insert the winding tree 70 into an intermediate storage location and release it.

Fig. 6: Der Anwickelbaum 70 wurde von einem Manipulator 71 aus der Zwischenlagerstelle entnommen und wird gegen den neuen Warenbaum 51 gepresst. Durch Weiterdrehen des Anwickelbaums 70 wird eine Tuchreserve gebildet. Der Anwickelbaum 70 beginnt nun den Warenbaum 51 im Gegenuhrzeigersinn zu umfahren, wobei er sich in Pfeilrichtung weiterdreht. Die Schlaufe des Gewebes 510 wird dabei weiter vergrössert.Fig. 6: The winding tree 70 was removed by a manipulator 71 from the intermediate storage location and is pressed against the new goods tree 51. By turning the Anwickelbaums 70 a cloth reserve is formed. The winding tree 70 now begins to bypass the goods tree 51 in the counterclockwise direction, and continues to rotate in the direction of the arrow. The loop of the fabric 510 is further enlarged.

Fig. 7: In der gestrichelten Position des Anwickelbaumes 70′ wird das Gewebe durch eine Schneideinrichtung 10 über die ganze Breite durchtrennt. Der Anwickelbaum wird gemäss Pfeil 71′ weitergeschwenkt bis in die ausgezogene Position. Der Gewebeabschnitt 510′ hängt frei vom neuen Warenbaum 51 herab. Es kann durch eine Faltvorrichtung 11, die in Richtung des Pfeils 11′ gegen den neuen Warenbaum 51 bewegt wird, zusammen mit dem Gewebe 510 auf dem neuen Warenbaum 51 angewickelt werden, wenn sich dieser gemäss Pfeil 51′ dreht. Der Gewebeabschnitt zur Webmaschine hin wird gleichzeitig gestrafft.Fig. 7: In the dashed position of the winding tree 70 ', the tissue is cut through a cutting device 10 over the entire width. The winding tree is pivoted further according to arrow 71 'into the extended position. The fabric section 510 'hangs freely from the new fabric tree 51. It can be wound by a folding device 11, which is moved in the direction of arrow 11 'against the new goods tree 51, together with the fabric 510 on the new goods tree 51 when it rotates according to arrow 51'. The fabric section towards the weaving machine is tightened at the same time.

Fig. 8: Die Greifarme 40a,40b haben den neuen Warenbaum 51 aus der Anwickelposition in eine Zwischenposition gebracht, in der der Warenbaum 51 durch einen Hilfsantrieb 54 weitergedreht wird, bis der Gewebeabschnitt 510 straff ist.8: The gripping arms 40a, 40b have brought the new goods tree 51 from the winding position into an intermediate position in which the goods tree 51 is rotated further by an auxiliary drive 54 until the fabric section 510 is taut.

Fig. 9: Die Greifarme 40a,40b setzen den neuen Warenbaum 51 in die Webmaschine 500a ein, worauf ein Antrieb innerhalb der Webmaschine die Aufwicklung des Gewebes bewerkstelligt.Fig. 9: The gripper arms 40a, 40b insert the new goods tree 51 into the weaving machine 500a, whereupon a drive within the weaving machine brings about the winding of the fabric.

Fig. 10: Die Greifarme 40a,40b holen den Anwickelbaum 70 aus der Anwickelposition und setzen ihn in eine Zwischenposition in Fig. 10 ein, von wo er durch den in Fig. 3 beschriebenen Manipulator 72 in die ursprüngliche Position gemäss Fig. 1 überführt wird.10: The gripping arms 40a, 40b fetch the winding tree 70 from the winding position and insert it into an intermediate position in FIG. 10, from where it is transferred into the original position according to FIG. 1 by the manipulator 72 described in FIG. 3 .

Die Ankoppelung des Warenbaums 51 im Transportgerät 102 ist in Fig. 11 dargestellt. Je ein Adapter 804′ in Form einer Lochscheibe mit einer Nut am äusseren Umfang wird auf beiden Seiten des Warenbaums 51 angeschraubt. Die Greifarme 40a,40b erfassen den Warenbaum 51 über den Umfang der Adapterscheiben 804′. Im Transportgerät wird der neue Warenbaum mittels einer Klauenkupplung 804 gehalten und angetrieben. Nach Positionieren des Warenbaums 50 mittels der Greifarme 40a,40b wird eine Antriebseinheit 803 für den Warenbaum 51 axial gegen diesen verschoben, indem ein mit der Antriebseinheit 803 verbundener Schlitten 810 mittels einer Vorrichtung 81, gebildet aus einem Antriebsmotor 811 und einer Spindel 812, gegenüber dem Seitenteil 20a des Transportgerätes verschoben wird.The coupling of the goods tree 51 in the transport device 102 is shown in FIG. 11. One adapter 804 'in the form of a perforated disc with a groove on the outer circumference is screwed onto both sides of the goods tree 51. The gripping arms 40a, 40b grasp the goods tree 51 over the circumference of the adapter disks 804 '. The new goods tree is held and driven in the transport device by means of a claw coupling 804. After positioning the goods tree 50 by means of the gripping arms 40a, 40b, a drive unit 803 for the goods tree 51 is axially displaced by a carriage 810 connected to the drive unit 803 by means of a device 81, formed from a drive motor 811 and a spindle 812, in relation to the latter Side part 20a of the transport device is moved.

Die Fig. 12, 13a und 13b zeigen die Lagerung und den Antrieb des neuen Warenbaums 51 und des Anwickelbaums 70. An einer Grundplatte 813 sitzt unten ein Gehäuse 801 einer Ankuppelvorrichtung 80 für den Warenbaum 51. Der Warenbaum 51 wird durch den Antrieb 803 verdreht, wenn er mit der Klauenkupplung 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 ein 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 aus über eine Welle 718 von einem Zahnradtrieb 719 angetrieben, dessen Antriebsrad 719′ konzentrisch mit dem Warenbaum 51 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 ortsfeste Kurvenbahn 714 ist am Seitenteil 20b befestigt. Sie gelangt in einem bestimmten Winkelbereich des Gehäuses 710 während seiner Verdrehung in Kontakt mit einer Rolle 713, die an einem Hebel 711 befestigt ist, der auf einem Zapfen 716 im Gehäuse 710 gelagert ist. Beim Auflaufen der Rolle 713 wehrend der Schwenkbewegung des Gehäuses 710 und somit des Hebels 711 auf dem Kurvensegment 714 bewegt sich die Rolle 713 mit dem entsprechenden Teil des Hebels 711 in Richtung auf die Achse des Warenbaums 51, wobei eine Druckfeder 712 mehr gespannt wird. Eine Mulde 715 auf der anderen Seite des Hebels wird dabeinach aussen geschwenkt. In dieser Lage kann der von unten gehobene Anwickelbaum 70 in die Mulde 715 eingelegt werden. Beim Zurückschwenken des Hebels 711 nach dem Einlegen des Anwickelbaums 70 gerät die Mulde 715 unter einen Vorsprung 710′ des Gehäuses 710, wodurch der eingelegte Zapfen des Anwickelbaums 70 verriegelt ist. Die Anwickeloperation ist weiter oben bereits beschrieben worden.12, 13a and 13b show the storage and the drive of the new goods tree 51 and the winding tree 70. A housing 801 of a coupling device 80 for the goods tree 51 sits on a base plate 813 below. The goods tree 51 is rotated by the drive 803, when coupled to the dog clutch 804, the coupling being effected by axially moving the carriage 810. A non-rotatable gear 802 is seated on the housing 801. A 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 via a shaft 718 by a gear drive 719, the drive wheel 719 'is mounted concentrically with the goods tree 51. 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 stationary Cam track 714 is attached to the side part 20b. It comes into contact with a roller 713, which is attached to a lever 711, which is mounted on a pin 716 in the housing 710 in a certain angular range of the housing 710 during its rotation. When the roller 713 runs up during the pivoting movement of the housing 710 and thus the lever 711 on the cam segment 714, the roller 713 moves with the corresponding part of the lever 711 in the direction of the axis of the fabric tree 51, whereby a compression spring 712 is tensioned more. A trough 715 on the other side of the lever is then pivoted outwards. In this position, the winding tree 70 raised from below can be inserted into the trough 715. When pivoting the lever 711 after inserting the winding tree 70, the trough 715 comes under a projection 710 'of the housing 710, whereby the inserted pin of the winding tree 70 is locked. The winding operation has already been described above.

Während Fig. 13a die Position des Manipulators 71 in der Uebernahmestellung für den Anwickelbaum 70 zeigt, stellt Fig. 13b eine Position während des Umfahrens des neuen Warenbaums 51 durch den Anwickelbaum 70 dar.13a shows the position of the manipulator 71 in the take-over position for the winding tree 70, FIG. 13b shows a position during the bypassing of the new goods tree 51 by the winding tree 70.

Wegen der Verstellbarkeit der Länge des Transportgeräts 102 für verschiedene Webbreiten müssen beispielsweise die Antriebswelle 718 gemäss Fig. 12 und der Anwickelbaum 70 als Teleskopstangen bzw. -rohre ausgebildet sein. Der rechte Teil des Anwickelbaums 70 in Fig. 12 bildet ein Teleskoprohr, während der linke Teil durch eine Teleskopstange und darauf sitzende Elemente 70˝ mit gleichem Durchmesser wie das Teleskoprohr gebildet wird. Wenn der Anwickelbaum 70 für eine neue Webbreite angepasst wird, ändert sich auch der Abstand der Segmente 70˝ am Anwickelbaum 70′ gemess Fig. 12.Because the length of the transport device 102 can be adjusted for different weaving widths, the drive shaft 718 according to FIG. 12 and the winding tree 70, for example, must be designed as telescopic rods or tubes. The right-hand part of the winding tree 70 in FIG. 12 forms a telescopic tube, while the left-hand part is formed by a telescopic rod and elements 70˝ sitting thereon with the same diameter as the telescopic tube. If the dressing tree 70 is adjusted for a new weaving width, also changes the distance of the segments 70˝ on the winding tree 70 'measured Fig. 12th
