Abstract

PURPOSE: To prevent the damage of a wire, and enhance the speed of the wind ing work by providing a guide roller capable of hooking the wire and protruding and recessing and a pair of guide members on a hook mechanism. CONSTITUTION: A wire W delivered from a wire supplying part 4 through a nozzle part 8 is automatically wound on an integrated type bobbin B by the circumferential motion including the insertion and separation of the part 8 to the bobbin B and the hooking motion of a hook mechanism. Thus, the winding work can be automated, and the speed of the work can be enhanced. In this case, the hooking motion of the wire W is performed by the protruding and recessing motion of a guide roller 24 capable of hooking the wire W and a pair of guide members 23 opposed with the inserting clearance 22 of the wire W hooked by the roller 24. At the hooking motion of the wire W, thus, the excessive bending of the wire can be prevented to suppress the damage of the wire W, and the wire W is also held by the clearance 22 between the members to prevent the slippage of the hooked wire W, so that the speed of the winding work can be increased.

9. Other structures and the like are appropriately modified and designed.

Further, in the above-mentioned embodiment, the winding structure in which one wire W is wound around the bobbin B is applied, but it can be applied to a structure in which a large number of wires are simultaneously wound. In this case, the winding tube 6 and the tension control mechanism 7 are installed. The numbers are arranged in parallel according to the number.

[0022]

As described above, according to the present invention, the wire rod fed from the wire rod supply portion through the nozzle portion is automatically moved by the revolving operation including the insertion and removal of the nozzle portion from the bobbin and the hooking operation of the hooking mechanism. Since the winding work is automated, the winding work can be automated, and the work speed can be increased. In particular, the above-mentioned wire rod catching operation is performed by the guide roller advancing / retreating operation capable of catching the wire rod and the guide roller. It is made up of a pair of guide members facing each other with a wire-insertion gap. Therefore, during the hooking operation of the wire, excessive bending of the wire can be prevented, damage to the wire can be suppressed, and It can be held by the insertion gap between the guide members to prevent the pulled wire rod from coming off,
Therefore, the winding work can be speeded up.

Further, at this time, the guide roller is configured to be freely rotatable, so that the guide roller can be freely rotated during the hooking operation of the wire rod to further suppress damage to the wire rod. By forming the leading end of the roller 24 into a taper surface having a tapered shape, the hooking and inserting operation of the guide roller can be smoothly performed, and a better winding operation can be performed.

As described above, the initial purpose can be sufficiently achieved.
