Abstract
The filament winding device includes a fiber feeding head for feeding a fiber bundle to a workpiece. The fiber feeding head includes a spreader roller and a damper mechanism. The fiber bundle is wound around the side surface of the spreader roller. The damper mechanism moves the spreader roller in a direction that shortens the path length of the fiber bundle as the tension of the fiber bundle increases. The damper mechanism moves the spreader roller in a direction that increases the path length of the fiber bundle as the tension of the fiber bundle decreases.
Claims10
A filament winding device configured to wind around a workpiece a fiber bundle formed of a plurality of fibers, the filament winding device comprising:
- a delivery head configured to move relative to the workpiece;
- and
- a fiber feeding head, with which the delivery head is provided, the fiber feeding head being rotatable relative to the delivery head,
- wherein the fiber feeding head includes:
- a spreader roller that has a side surface around which the fiber bundle is wound, the spreader roller being configured to widen the fiber bundle on the side surface;
- and
- a damper mechanism supporting the spreader roller, the damper mechanism being configured to suppress variation in tension of the fiber bundle supplied to the workpiece,
- wherein the damper mechanism moves the spreader roller in a direction that shortens a fiber bundle path length as a tension of the fiber bundle increases, and moves the spreader roller in a direction that increases the fiber bundle path length as the tension of the fiber bundle decreases.
