The present invention makes it possible to increase production efficiency while reducing costs. A filament winding automated system according to the present invention includes a winding device winding a fiber bundle R paid out from a head portion 12, 13, around a mandrel M1, an installing device 5 installing the mandrel around M1 which no fiber bundle has been wound yet, at a winding position, a discharging device 5 discharging the mandrel around which the fiber bundle has already been wound, from the winding position, a delivery device 3 holding and delivering the fiber bundle R from the mandrel around which the fiber bundle has already been wound to a mandrel M1 around which no fiber bundle has been wound yet, and a cutting device cutting the fiber bundle R, and after winding is completed, the delivery device 3 holds the fiber bundle R paid out from the head portion 12, 13, the cutting device cuts and separates the fiber bundle R from the mandrel around which the fiber bundle has already been wound, the discharging device 5 discharges the mandrel around which the fiber bundle has already been wound, the installing device installs the mandrel M1 around which no fiber bundle has been wound yet, and the winding device starts winding the fiber bundle R held by the delivery device 3, around the mandrel M1 around which no fiber bundle has been wound yet.
