As shown in FIG. 2, the wire bobbin winding device 9 around an empty bobbin includes a swingable arm 15, a swivel arm 16 attached to the tip of the arm 15, and a wire clamp 17 attached to the tip of the swivel arm. The swivel arm 16 swivels between the fully wound bobbin and the storage line capstan, and the clamp 17 holds the wire rod. After the wire rod is cut, when the full bobbin retracts, the bobbin 6 is replaced and the empty bobbin 6 is sent onto the child carriage 4. The empty bobbin is located at a position 6c slightly above the receiving roller 14. At this time, the swing arm 15 swings 15a, the swing center of the swing arm 16 is aligned with the center of the bobbin, the wire rod gripped by the clamp 17 abuts on the bobbin, and the swing arm 16 swings around the bobbin body, Wind while rotating. By this winding, the wire wound around the storage capstan is naturally rewound.

The full bobbin is retracted by being supported by the slide frame 11 which is guided by the gate type frame 18 and moves up and down. Reference numeral 5a shown in FIGS. 2 and 3 denotes a retracted full-winding bobbin.

While the wire rod is wound around the empty bobbin 6 by the winding device 9, the storage wire capstan 7 is largely swung 7a by the swing of the arm 12, as shown in FIG. A tread roll is performed.

When the wire rod end is fixed to the empty bobbin 6 by the winding, the storage line capstan 7 and the winding device 9 are returned to the standby position, the bobbin supporting shaft is retracted, and the empty bobbin is moved to the table by the child carriage 4. The lifter is transferred onto the lifter 3 and is mounted on the bobbin mounting portion by raising the lifter.

The bobbin guiding device 10 is, as shown in FIG.
A turntable 20 provided on the turntable 20 and a turnable bracket 21 having a bobbin supporting shaft attached to the turntable 20 for guiding the empty bobbin sent to the right side of the figure by a conveyor. The bobbin 19 approaches and the bobbin support shaft is inserted, and by rotating the turntable 20 and turning the bracket 21, the empty bobbin is inverted as shown in FIG.
To the position of 4 and the movement of the guidance carriage 19 causes the child carriage 4 to move.
Position it on top.

When the empty bobbin 6 on which the wire rod is fixed is transferred toward the main body 1 of the wire rod manufacturing apparatus, the empty bobbin 6 is replaced and the full-winding bobbin 5a retracted upward is lowered, and the bobbin guiding device 10 operates in the opposite direction to the above. Then, the full-winding bobbin is guided to the position of 5b, thereafter separated from the bobbin guiding device, and conveyed to a predetermined place by a conveyor.

In the figure, 22 is a cutter device, 23 is a guide groove of a child carriage, 24 is a rotation diameter of a twisted wire rotating body, 25 is a bobbin located on a bobbin core during operation, 26 is a position of a top plate when a table lifter is raised, 27 Is a position of the top plate when the table lifter descends, 28 is a traveling rail of the parent carriage, 29 is a wheel of the parent carriage, and 30 is a bobbin support shaft capable of vertical body movement.

The above-mentioned various operations in the present invention are automatically performed by a command from a sensor or the like.
