Filament winding device

A filament winding device comprising:

• a liner supporter that supports a liner to be rotatable about an axis of the liner;
• a helical winding unit including fiber bundle guides aligned in a circumferential direction of the liner and guide fiber bundles to the liner;
• the filament winding device helical-winding the fiber bundles supplied through the fiber bundle guides onto the rotating liner by moving the liner supporter and the helical winding unit relative to each other in an axial direction of the liner;
• a fiber bundle retainer configured to temporarily retain the fiber bundles at least when the liner is replaced, the fiber bundle retainer including:
• a reel member including an outer peripheral portion having pins that are movable in the axial direction relative to the fiber bundles supplied through the fiber bundle guides and rotatable about the axis of the liner, the reel member being capable of winding the fiber bundles onto the outer peripheral portion;
• a first cutting unit configured to cut a part of each of the fiber bundles in the circumferential direction, the part being between a part of the fiber bundle wound on the outer peripheral portion and a part of the fiber bundle wound on the liner;
• and
• a second cutting unit that is different from the first cutting unit and configured to cut a part of each of the fiber bundles in the axial direction, the part being wound on the outer peripheral portion,
• wherein the second cutting unit cuts the fiber bundles by moving toward one side in the axial direction,
• the fiber bundle retainer includes at least one fiber bundle pressing member configured to restrict movement of the fiber bundles wound on the outer peripheral portion of the reel member toward the one side in the axial direction, and
• the at least one fiber bundle pressing member comprises plural fiber bundle pressing members, and the fiber bundle pressing members are provided to oppose each other with the second cutting unit therebetween.
