Description

Wire winding equipment

The present invention relates to a wire winding device, and more particularly to a wire winding device for winding the wire in the bobbin.

In general, the welding wire is completed after the drawing process and is wound on the spool when the finished product is shipped.

This welding wire is wound by a winding machine that continuously supplies the spool to the rotating device so that a certain amount of wire is wound around the spool.

In the case of a welding wire used in a place where a lot of manual welding is performed in a shipyard or a large construction site, it is necessary to improve the operator's preference, convenience of welding work, and supplyability of the welding wire.

The welding wire is wound on a spool having a predetermined width according to the multiple of the wire diameter (diameter) of the wire to be wound on the spool. Since the wire is wound in multiple layers, it must be wound by the same amount of wire in each layer to be aligned.

However, a surface flaw of the wire may be generated by friction between the wires, etc. during the winding of the welding wire, and the flaw may cause a kink phenomenon when the coil is wound on the spool of the welding wire.

In addition, as the winding layers are not arranged side by side when the wires are wound in multiple layers, and the arrangement of the winding layers is disturbed, the wires wound on the next winding layer are also wound in an irregular arrangement.

Therefore, in the related art, a worker has to monitor the winding machine at all times so that such misalignment winding does not occur.

In other words, if a misalignment occurs by visually identifying the normally aligned spool and the abnormally wound shape, stop the operation of the winding machine and forcibly make a width between the wires by a driver or the like in a part of the wound winding, The layer was no longer abnormally wired and allowed to wind to the next layer.

This is because the width of the spool can not be adjusted by adjusting the amount of winding the wire in a single winding layer has a problem that the productivity of the spool is reduced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wire winding device for preventing misalignment winding, such as wire twist or line drop of a wire wound on a bobbin by installing a guide part for guiding the wire to solve the above problems.
