Abstract: Control closely based on sets of winding data of a fiber bundle is performed even if at least one set of the winding data is skipped. A controller includes a data conversion unit, a reference data setting unit, a transfer unit, and a selector. The data conversion unit converts sets of first winding data generated based on winding conditions into sets of second winding data in which a processing order number is associated with information of a state of a winder. The reference data setting unit sets some of the second winding data as sets of reference data in advance. The transfer unit transfers a selected set of the second winding data to the winder, each time a unit time elapses. The selector is able to set an override value that is used for determining a skip number.

IPC: B65H75/28
Abstract: A roller unit in which loosening of a fiber bundle is suppressed and the fiber bundle is easily held and released is provided. A roller unit 70 includes a guide roller 71 onto which a fiber bundle F is placed and a first yarn holding member 82 and a second yarn holding member 83 attached to a leading end portion of the guide roller 71 in the axial direction. The first yarn holding member 82 and the second yarn holding member 83 are arranged to be able to make contact with each other and to be separated from each other, and can hold the fiber bundle F by sandwiching the same.

Abstract: In a filament winding apparatus, a supplying device supplies fiber bundles to a surface of a core material. A moving part is movable relative to the core material, and rotatable around a rotational axis extending in a vertical direction. A small diameter aligning guide part is placed at the moving part and has an opening portion through which the core material can pass. The small diameter aligning guide part guides fiber bundles to an outer peripheral surface of the core material such that the fiber bundles are arranged side by side in a circumferential direction of the core material. The tightening fiber bobbin supporting part is placed at the moving part and rotates around a center of the opening portion. A winding guide rotates with the tightening fiber bobbin supporting part and guides a tightening fiber bundle drawn from a tightening fiber bobbin toward the surface of the core material.

Abstract: A filament winding device includes: a helical winder which winds a fiber bundle around a liner; a bobbin supporting shaft which rotatably supports a bobbin for providing the fiber bundle to the helical winder and a bobbin different from the bobbin in a state in which winding-initiation ends of the fiber bundle wound around the bobbin and winding-termination ends of the fiber bundle wound around the bobbin connect to each other; and a fiber bundle storage unit. The fiber bundle storage unit has a stopper which can switch the fiber bundle storage unit between a storage state in which the fiber bundle is stored in the fiber bundle storage unit and a storage-released state in which the fiber bundle has been released from storage in the fiber bundle storage unit and the fiber bundle is supplied from the fiber bundle storage unit to the helical winding unit.
