(54) Automatic winder


(57) The present invention improves the shape of a yarn path to reduce the load on a yarn to increase a winding speed, while still preventing the tension breakage of the yarn and an increase in the amount of fluffs. An automatic winder includes a magazine type bobbin housing device 20, a holding device 3 for yarn supplying bobbins 4, and a bobbin chute 24 that guides a bobbin 4 falling from the bobbin housing device 20 to the holding device 3. The holding device 3 is provided with a first pawl 31 and a second pawl 32 which operate as holding means for the bobbins 4 and rotative moving shafts 33 and 34 which rotatively move both pawls 31 and 32. A bottom guide 24b of the bobbin chute 24 is adapted to be pivotable with respect to a main body 24a. Accordingly, when the bobbin chute 24 is closed, a path is formed through which the falling bobbin 4 is guided. Rotatively moved positions of the first pawl 31 include a position at which the first pawl 31 receives the bobbin 4 from the bobbin housing device 20, a position at which the first pawl 31 holds the bobbin during a winding operation, and a position at which the first pawl 31 discharges the bobbin to a side of a frame 2 (Fig. 1).
