FILAMENT WINDING METHOD AND FILAMENT WINDING APPARATUS

摘要

Provided are a filament winding method and a filament winding apparatus, in which, when a new bobbin is mounted on a bobbin rotation driving device, the control device is programmed to rotate the bobbin and oscillate a dancer while maintaining a state where a distal end of filament unwound through the dancer is fixed further beyond the dancer and the filament is stretched. The control device is programmed to obtain a bobbin diameter of the bobbin mounted on the bobbin rotation driving device based on a length of the dancer, an oscillation angle of the dancer, and a rotation angle of the bobbin.

1. A filament winding method including:
a bobbin rotation driving device, on which a bobbin, upon which filament is wound, is mounted, the bobbin rotation driving device driving and rotating the bobbin, a dancer that oscillates in order to apply certain tension to the filament unwound from the bobbin, and a control device that is programmed to control the bobbin rotation driving device, the filament winding method comprising: when a new bobbin is mounted on the bobbin rotation driving device, oscillating the dancer by rotating a bobbin by using the control device while maintaining a state where a distal end of the filament unwound through the dancer is fixed further beyond the dancer and the unwound filament is stretched; and obtaining a bobbin diameter of the bobbin mounted on the bobbin rotation driving device, by using the control device, based on a length of the dancer, an oscillation angle of the dancer, and a rotation angle of the bobbin.
