Filament winding apparatus

摘要

A filament winding apparatus prevents a fiber bundle supplied to a liner from interfering with other fiber bundles and fiber supplying guides. First and second guide units include a plurality of fiber supplying guides arranged radially and extending and contracting in a direction approximately perpendicular to a liner central axis. When a fiber bundle supplied from a first supplying guide of the first guide unit crosses between a second supplying guide of the second guide unit and the liner, the distance from the second supplying guide to the liner central axis is made larger than the distance from the first supplying guide to the liner central axis, and in the reverse case, the distance from the first supplying guide to the liner central axis is made larger than the distance from the second supplying guide to the liner central axis.

1. A filament winding apparatus configured to wind a fiber bundle around a liner, comprising:
a first guide unit and a second guide unit each comprising a plurality of fiber supplying guides arranged radially and extending and contracting in a direction approximately perpendicular to a central axis of the liner; a driving unit configured to change an amount of extension or contraction of the fiber supplying guides; and a controller configured to adjust a distance between the fiber supplying guides and the central axis of the liner by controlling the driving unit, wherein when a fiber bundle supplied from a fiber supplying guide of the first guide unit crosses between a fiber supplying guide of the second guide unit and the liner, the controller makes the distance from the fiber supplying guide of the second guide unit to the central axis of the liner larger than the distance from the fiber supplying guide of the first guide unit to the central axis of the liner, and when a fiber bundle supplied from the fiber supplying guide of the second guide unit crosses between the fiber supplying guide of the first guide unit and the liner, the controller makes the distance from the fiber supplying guide of the first guide unit to the central axis of the liner larger than the distance from the fiber supplying guide of the second guide unit to the central axis of the liner.
