Description

Wire unwinding system and unwinding method for drumless welding {Pay off system and Pay off method for Bulk Packaged Drumless Welding Wire}

The present invention relates to a system and method for unwinding a welding wire, and more particularly, to a system and method for unwinding a wire for drumless welding 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, among the forms of stacking and storing a large-capacity pail pack in the form of a loop, an automatic welding line or a robot welding line applies a winding type of pattern layer lamination method in which torsional stress is applied to the wire (hereinafter referred to as "pattern layer lamination method"). are doing

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.

As a prior invention related to the pattern layer stacking method, Korean Patent Registration No. 10-1418493 (filing date 2013.10.02) has been proposed. The prior invention is characterized in that the wire maintaining straightness is wound while being rotated at a constant pitch without tangling.

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 unit weights 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.

In addition, 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.

On the other hand, in order to solve the above-described problem, the welding wire wound through the lamination of the pattern layers may be provided without being separately packaged in a one-time fiber drum.

However, in this case, the existing one-time fiber drum serves as an adapter when used in various categories of existing welding equipment,

Since a separate adapter is not provided for the welding wire wound through the lamination of patterned layers instead of being packaged in a fiber drum, a problem in that it cannot be easily used in existing welding equipment may occur.
