Spun yarn winding device and spun yarn winding facility

A spun yarn winding device for winding spun yarns onto winding bobbins, the spun yarn winding device comprising:

• a machine body;
• a turret including bobbin holders that hold the winding bobbins and which is rotatable with respect to the machine body;
• a feeding roller that is fixed in position relative to the machine body, is not in contact with the winding bobbins, and feeds yarns to the winding bobbins at a speed equal to or faster than a speed at which the yarns are wound on the winding bobbins;
• a traverse device which is fixed in position upstream of the feeding roller with respect to an advance direction of the yarns and which traverses the yarns;
• a peripheral speed detection unit that detects a peripheral speed of the winding bobbins;
• and
• a control unit that is programmed to, during a yarn winding period, perform a basic operation to maintain a free length of the yarns at a standard length by controlling a rotational angle of the turret, the free length being lengths of portions of the yarns which are located between the feeding roller and the winding bobbins.
