发明名称 Filament winding apparatus
摘要 A filament winding apparatus that prevents excessive unraveling of a fiber bundle due to variations in the speed at which the fiber bundle is wound includes a hoop winding device having a wrapping table, a bobbin support unit, a braking unit, a slack removal unit, a detector, and a controller. The slack removal unit absorbs slack caused by the difference between winding and unraveling speeds of the fiber bundle. The detector detects whether the amount of slack absorbed is equal to or greater than or is less than, a predetermined amount. When the amount of slack is equal to or greater than the predetermined amount, the controller increases the braking force of the braking unit for braking rotation of a bobbin. When the amount of slack is less than the predetermined amount, the controller reduces the braking force of the braking unit for braking rotation of the bobbin.

主权项 1. A filament winding apparatus winding a fiber bundle onto a surface of a liner with a hoop winding device, wherein the hoop winding device comprising: a wrapping table rotated around an axis of the liner; a bobbin support unit provided in the wrapping table and supporting a bobbin of the fiber bundle; a braking unit braking rotation of the bobbin supported by the bobbin support unit; a slack removal unit absorbing slack caused by difference between winding speed of the fiber bundle pulled out from the bobbin and wound onto the surface of the liner and unraveling speed of the fiber bundle unraveled from the bobbin by rotation of the bobbin; a detector detecting that the slack absorbed by the slack removal unit is not less than a predetermined value and that the slack absorbed by the slack removal unit is less than the predetermined value; and a controller increasing braking power of the braking unit based on a detection signal from the detector detecting that the slack absorbed by the slack removal unit is not less than the predetermined value and reducing braking power of the braking unit based on a detection signal from the detector detecting that the slack absorbed by the slack removal unit is less than the predetermined value.
