Wire winding system and winding method for Bulk Packaged Drumless Welding Wire}

The present invention relates to a winding system and method for winding a welding wire, and more particularly, to a system and method for winding a drumless welding wire using a twist control pattern layer lamination method in consideration of manufacturing cost and environment.

Welding wires are generally provided in a wound state. This has a high volumetric efficiency, and since the welding wire is used in a sensitive operating environment even during welding, the welding quality and the like vary greatly accordingly, so there is an advantage in securing ease of use in a wound state.

As the winding type described above, there are typically a type of winding on a small-capacity plastic spool and a type of stacking and storing in a loop form in a large-capacity pail pack.

In particular, welding wire stacked and housed in a large-capacity pail pack in the form of a loop adopts a winding form of a pattern layer stacking method in which torsional stress is controlled (hereinafter referred to as "pattern layer stacking method").

Wire products wound by the pattern layer stacking method have a great advantage in use because they can relieve the twist stress in the reverse direction applied to the wire during winding in proportion to the consumption of the wire during welding.

However, the prior art including the prior invention utilizes an octagonal, hexadecimal, or hexagonal box-shaped packaging container using a paper fiber drum or corrugated cardboard that is used once and discarded, or uses 250kg or 300kg of welding wire in a square box. , 350kg, 400kg, and 450kg units of weight are used for packaging by winding and storing.

Packaging materials provided in various specifications are mostly discarded without being recycled after exhausting all the wires at the welding site.

On the other hand, since the bulky fiber drum is bulky during transportation in a product state or a waste state, transportation costs incurred in the field are also a considerable burden.

Furthermore, environmental problems caused by waste and resources used to produce fiber drums are a self-evident fact, and solutions to the above-mentioned cost and environmental problems are required in the industry.

It is characterized in that it further comprises a control unit so that the wire is continuously provided so that the wires are stacked without tangling by interlocking and adjusting each one.

Here, the control unit controls the wire supply amount and supply speed of the wire straightness straightening unit, the vertical position of the turntable adjusted in proportion to the amount of stacked wires, and the rotational speed of the turntable and eccentric pliers adjusted so that the wires are stacked without tangling. When the turntable reaches the lowest end of the setting range, the openable drum is partially opened so that the stacked layer fixing unit is operated, and when the stacked layer is PP bent, the openable drum is fully opened It is characterized in that the stacked layer discharge unit is operated so that the stacked layer is discharged.
