Definitions

  • the present invention relates to the conveyance of bobbins in yarn processing machines such as false twisting machines.
  • PTL 1 Japanese Patent Application Laid-Open H4-280777 discloses a package transfer method applied to a winder or the like.
  • this transfer method when a package on a creel becomes empty and needs to be replaced with a full package according to the operation of a winder, the package is replaced via a creel loader that holds the full package horizontally.
  • a package that is empty can be described as an empty bobbin.
  • a full package can be described as a full bobbin.
  • the full packages are temporarily placed on a package supporter once before they are suspended on the creel.
  • Pegs for hanging the package are provided on both sides of the package supporter.
  • full packages are suspended on one side of the package supporter, and the pegs on the other side are left without the package.
  • the side of the package supporter with the pegs in the no-package state is ready to face the creel loader.
  • the creel loader removes the empty packages from the creel of the winder, transfers them to the package supporter, and hangs them on each of the pegs in the no-package state.
  • the package supporter is then reversed, and the side on which the full package is hung faces the creel loader.
  • the creel loader transfers the full packages from the package supporter to the creel of the winder where it has just taken the empty packages.
  • the creel loader then takes the adjacent empty packages on the creel and transfers them to the package supporter.
  • PTL 2 Japanese Patent Application Laid-Open H5-319696 discloses a package transfer method used for a weft yarn supply system to loom or the like.
  • a package carrier capable of grasping a plurality of packages can supply packages to a weft yarn supply system and collect an empty tube.
  • the controller controls the stocker and the traveling creel cart so that the stocker and the traveling creel cart cooperatively perform the exchange operation of replacing empty bobbins of the stocker with full bobbins of the traveling creel cart by alternating a following first process and a following second process.
  • the full bobbins hung on one row of cart pegs of the traveling creel cart are moved to one row of stocker pegs that is in a bobbin-less state to set one row of the cart pegs in a bobbin-less state.
  • one row of empty bobbins hung on the stocker pegs are moved to one row of the cart pegs that is in a bobbin-less state after the removal of the full bobbins in the first process to set one row of the stocker pegs in a bobbin-less state.

    sowie Steuern des beweglichen Spulengatterwagens (10), nachdem der bewegliche Spulengatterwagen (10) volle Spulen (5) zur Lagereinrichtung (20) befördert und die vollen Spulen (5) gegen leere Spulen (6) in der Lagereinrichtung (20) ausgetauscht hat, die leeren Spulen (5) an einen unterschiedlichen, anderen Ort als die Lagereinrichtung (20) zu befördern.
  2. Spulenbeförderungssystem (1) nach Anspruch 1, wobei
    die Anzahl der Ebenen der Lagereinrichtungszapfen (26), die durch die Lagereinrichtung (20) bereitgestellt werden, gleich der Anzahl der Ebenen der Wagenzapfen (13), die durch den beweglichen Spulengatterwagen (10) bereitgestellt werden, ist und
    die Steuereinheit (40) die Lagereinrichtung (20) und den beweglichen Spulengatterwagen (10) derart steuert, dass in dem Austauschvorgang alle leeren Spulen (6) in der Lagereinrichtung (20) durch alle vollen Spulen (5) im beweglichen Spulengatterwagen (10) ersetzt werden.
  3. Spulenbeförderungssystem (1) nach Anspruch 1 oder 2, wobei
    der bewegliche Spulengatterwagen (10) volle Spulen (5) von einer Einbauposition einer Spinnwickeleinrichtung (60), die Garn auf eine leere Spule (6) wickelt, um eine volle Spule (5) zu bilden, zu einer Einbauposition der Lagereinrichtung (20) befördert, und
    der bewegliche Spulengatterwagen (10) die leeren Spulen (6), die durch den Austauschvorgang von der Einbauposition der Lagereinrichtung (20) gezogen werden, derart befördert, dass die leeren Spulen (6) zur Einbauposition der Spinnwickeleinrichtung (60) zurückgebracht werden.
  4. Spulenbeförderungssystem (1) nach einem der Ansprüche 1 bis 3, wobei
    sich der Lagereinrichtungszapfen (26) kreisförmig entlang eines geschleiften Wegs bewegen kann und
    die Reihe der Lagereinrichtungszapfen (26), die den Wagenzapfen (13) volle Spulen (5) oder leere Spulen (6) zuführen, durch die kreisförmige Bewegung geändert wird.
  5. Spulenbeförderungssystem (1) nach einem der Ansprüche 1 bis 4, wobei
    die Steuereinheit (40) konfiguriert ist, den Spulenübertragungsroboter (30) zu steuern, und
    die Steuereinheit (40) den Spulenübertragungsroboter (30) derart steuert, dass der Spulenübertragungsroboter (30) wartet, ohne den Vorgang des Entnehmens voller Spulen (5) von der Lagereinrichtung (20) durchzuführen, während der Austauschvorgang durchgeführt wird.
  6. Spulenbeförderungsverfahren, das Folgendes umfasst:
    eine Lagereinrichtung (20), die mehrere Reihen von Lagerzapfen (26) aufweist und eine volle Spule (5) und eine leere Spule (6) auf jeden Lagerzapfen (26) hängen und darauf lagern kann;
    einen Spulenübertragungsroboter (30), der eine volle Spule (5), die in der Lagereinrichtung (20) gelagert ist, entnimmt und die volle Spule (5) an einem Spulengatter (71) einer Garnverarbeitungsmaschine (70) befestigt und eine leere Spule (6) vom Spulengatter (71) entnimmt und die leere Spule (6) in der Lagereinrichtung (20) lagert; und
    einen beweglichen Spulengatterwagen (10), der mehrere Reihen von Wagenzapfen (13) aufweist und eine volle Spule (5) oder eine leere Spule (6), die auf jedem Wagenzapfen (13) hängen, befördert; wobei
    das Spulenübertragungsverfahren ein Verfahren in einem System ist, in dem die Lagereinrichtung (20) konfiguriert ist, volle Spulen (5), die auf die Wagenzapfen (13) des beweglichen Spulengatterwagens (10) gehängt sind, zu den Lagereinrichtungszapfen (26) bewegen zu können und leere Spulen (6), die auf die Lagereinrichtungszapfen (26) gehängt sind, zu den Wagenzapfen (13) bewegen zu können,
    die Anzahl der Reihen der Lagereinrichtungszapfen (26), die durch die Lagereinrichtung (20) bereitgestellt werden, gleich der Anzahl der Reihen der Wagenzapfen (13), die durch den beweglichen Spulengatterwagen (10) bereitgestellt werden, puls eins ist,
    in einem Zustand, in dem eine Reihe der Lagereinrichtungszapfen (26) spulenfrei ist und leere Spulen (6) auf alle restlichen Reihen der Lagereinrichtungszapfen (26) gehängt sind,
    ein Austauschvorgang des Ersetzens von leeren Spulen (6) in der Lagereinrichtung (20) durch volle Spulen (5) im beweglichen Spulengatterwagen (10) durchgeführt wird, durch abwechselndes Durchführen der folgenden Prozesse:
    eines ersten Prozesses des Bewegens voller Spulen (5), die auf eine Reihe von Wagenzapfen (13) des beweglichen Spulengatterwagens (10) gehängt sind, zu einer Reihe der Lagereinrichtungszapfen (26), die sich in einem spulenfreien Zustand befindet, derart, dass eine Reihe der Wagenzapfen (13) in einen spulenfreien Zustand versetzt wird; und
    eines zweiten Prozesses des Bewegens einer Reihe leerer Spulen (6), die auf die Lagereinrichtungszapfen (26) gehängt sind, zu einer Reihe der Wagenzapfen (13), die sich in einem spulenfreien Zustand befindet, nach dem Entnehmen der vollen Spulen (5) im ersten Prozess, derart, dass eine Reihe der Lagereinrichtungszapfen (26) in einen spulenfreien Zustand versetzt wird, und
    nachdem der bewegliche Spulengatterwagen (10) volle Spulen (5) zur Lagereinrichtung (20) befördert und die vollen Spulen (5) gegen leere Spulen (6) in der Lagereinrichtung (20) ausgetauscht hat, der bewegliche Spulengatterwagen (10) die leeren Spulen (6) an einen unterschiedlichen, anderen Ort als die Lagereinrichtung (20) befördert.
