The present invention relates to a winding device for winding a wire rod such as a thread or a thin steel wire to a bobbin, and more specifically, to finely control the reciprocating transfer distance of the guide roller for guiding the wire rod wound on the bobbin. By winding the wire rod evenly to the tapered bobbin to prevent the scattering of the wire rod wound on the bobbin relates to a winding guide device for effectively unwinding and effectively preventing the wire rod from being broken.

In general, wire rods such as seals, steel wires, and wires are wound in bobbins for the efficiency of transportation and storage in the manufacturing process, and for the unwinding of wire rods in use. As shown in Fig. 1, it has a generally cylindrical shape and a taper is formed by gradually increasing the diameter at both side portions.

Existing bobbin is wound around the inner periphery of the tapered wire with a certain length, and can be produced in a variety of shapes and diameters according to the type of wire, most wires produced from the drawer in the manufacturing process to a certain length The wire rod wound on a roll or in a large capacity on a roll in a manufacturing process is moved to a predetermined length depending on a field of use.

In the winding process, a guide device for guiding the wire rod is required so that the wire rod is evenly wound on the outer circumference of the bobbin. Referring to FIG. 2 in the drawing, a guide device for winding is a bobbin (1). When the wire rod is rotated so that the wire rod is reciprocated, the wire rod is reciprocated to guide the wire rod to the bobbin 1 so that the wire rod is evenly wound around the outer periphery of the bobbin 1.

However, in the existing wire winding guide device, the wire rod is not wound around the outer periphery of the tapered sides of the bobbin as the guide rollers for guiding the wire to the bobbin reciprocate only a certain distance, so the wire rod is formed on the inner periphery of the bobbin. In the case of winding in the wire rod wound around the tapered both sides is a situation that occurs.

That is, when the wire rod is wound on the inner circumferential edge of the bobbin at a predetermined thickness, a space is generated between both side tapered surfaces of the bobbin and both ends of the wound wire rod, so the wire rod wound in both directions in which the taper is formed flows down. As a result, the wire rod is twisted and uncoiled during use, which is inconvenient to use, and as a result, the wire rod is broken.

The present invention is a technique devised to solve the problems according to the conventional wire winding guide device as described above, finely control the reciprocating transfer distance of the guide roller for guiding the wire wound on the bobbin finely wire rod on the tapered bobbin overall The main purpose of the present invention is to provide a winding guide device which prevents the wire rods wound on the bobbin from being scattered evenly and effectively prevents the wire rods from breaking off.

That is, when the motor 31 drives the feed shaft 32 under the control of the sensor unit 33 and rotates the feed shaft 32, the stopper 17 fastened to the right and left screw portions of the feed shaft 32 is positive. As the distance between the stoppers 17 is widened and the width of the stopper 17 is increased, the reciprocation distance of the transfer switching device 20 is increased as a result, so that the reciprocation distance of the guide roller 2 for guiding the wire is widened. The wire is evenly wound on both sides of the tapered surface.

Therefore, the wire rod is guided by the guide roller 2 and evenly wound up to both tapered surfaces of the bobbin 1, so that the wire rod does not scatter and is smoothly wound or unwound so that it does not break when used.

In addition, when the winding process is completed on the bobbin (1), the motor 31 is driven in the reverse direction to rotate the feed shaft 32 in order to perform the winding process of the next sequence, to transfer both stoppers 17 to the first position to the next position Will do the work.

The preferred embodiments of the present invention have been described above with reference to the present invention, and are not limited to the above embodiments, and those skilled in the art through the above embodiments do not depart from the gist of the present invention. Can be implemented in a variety of changes.

As described above, according to a preferred embodiment of the present invention, the wire rod is wound evenly from the bobbin to the tapered surface by finely adjusting the reciprocating transfer distance of the guide roller for guiding the wound wire rod to the bobbin. It is to provide the effect of preventing the problem that the wire is twisted in the process of use is not smooth or broken by winding or loosening without being scattered smoothly.
