1. A fiber bundle winding device for winding a fiber bundle onto a bobbin, the fiber bundle winding device comprising:
a traverse guide configured to guide the fiber bundle to the bobbin; and
a controller configured to control the traverse guide according to a rotation of the bobbin, wherein
the traverse guide is configured to move parallel to a center axis of the bobbin,
the controller is configured to perform:
first movement control that moves the traverse guide in such a manner as to wind the fiber bundle onto the bobbin in a predetermined first area extending in a direction of the center axis of the bobbin; and
second movement control that moves the traverse guide in such a manner as to wind the fiber bundle onto the bobbin in a second area being smaller than the first area and having ends that are located within the first area and at different positions from respective ends of the first area, and
the first movement control and the second movement control are performed at a ratio of N:1, where N is an integer of more than 1;
wherein
the controller is configured to control the traverse guide with a winding ratio that is set such that turn-back points of the fiber bundle wound during the first movement control are evenly distributed in a circumferential direction of the bobbin, where the winding ratio is defined as the number of rotations of the bobbin during one reciprocation of the traverse guide along the direction of the center axis of the bobbin;
the controller sets the winding ratio such that turn-back points of the fiber bundle wound during the second movement control are evenly distributed in the circumferential direction of the bobbin;
the first movement control and second movement control are repeatedly executed; and
N is constant while the first and second movement controls are repeatedly executed.
