Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile pack of welding wire, and more particularly to a pile pack of welding wire suitable for continuous use from one pile pack to the next.

[0002]

2. Description of the Related Art In recent years, a large number of welding robots have been used with the progress of FA. Accordingly, containers of solid wire for carbon dioxide welding are also shifting from spool-wound containers to large-capacity pail packs suitable for long-term continuous use. As for the pail pack itself, it has become necessary to devise a way to enable continuous use from one pail pack to the next.

As a technique for responding to such a demand, for example, Japanese Patent Publication No. 3-33434 discloses a pail pack 1 as shown in FIG. 1 'is pulled out from the inside of the holding member 5 at the upper part of the wire similarly to the start end, and the wire end attachment part 13 provided on the upper inner wall of the outer cylinder 2 is drawn out in the same manner as the start end. Is disclosed.

[0004]

However, the above prior art has the following problems. Since the wire is firmly attached to the wire end attaching portion, the wire is deformed by an excessive force at the time of removal, and the bead meanders when welded with the deformed wire.

[0005] Therefore, when removing the wire, it is necessary to cut the end of the wire with pliers or the like. Since the removal operation is troublesome during the continuous welding, there is a concern that the wire end portion may be dropped off in a timely manner and may not be found. It is an object of the present invention to solve such a problem and to propose a pile pack of welding wires in which the end of the wire can be recognized and removed very easily.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a welding wire housed in a loop between an inner cylinder and an outer cylinder in a vertical double cylindrical structure pail pack, and an upper portion of the laminated wire. In a pile pack of welding wires comprising a donut-shaped holding member for holding the holding member and a cushioning material inserted between the holding member and the lid, the end of the wire is pierced and locked by the cushioning material. This is a pile pack of welding wires characterized by the following.

[0007]

According to the present invention, since the end of the wire of the pail pack is pierced and locked by the cushioning material immediately below the lid, the place where the wire is located can be easily searched at the time of connection work, and The removal operation is very simple without the need for a strong force because it only requires pulling out the wire pierced and locked by the cushioning material (such as a sponge), and all of the above-mentioned problems are eliminated.

FIG. 1 is a sectional view of an embodiment of the present invention, and FIG.
FIG. As shown in FIG. 1, a 300 kg wound pail pack 1 composed of a double cylinder of an inner cylinder 3 and an outer cylinder 2 fixed to a bottom plate portion 11 stores a wire in a loop-shaped laminated body 4. The wire start end (not shown) is taken out from the inside of the holding member 5 as in the related art, and is attached to a wire take-out device (not shown).

According to the present invention, the wire end portion 12 is inserted into a cushioning material (sponge) 15 normally inserted between the holding member 5 and the lid 10 of the pail pack, as shown in FIGS. Locking (pushing and stopping). Reference numeral 14 denotes a wire end fixing portion that is pierced and locked. This allows the wire end to be opened when the lid 10 is opened during use.
12 can be checked at a glance, and it can be easily pulled out.

[0010]

According to the present invention, the end of the wire housed in the pail pack can be easily found and easily removed, so that the wire connection workability under continuous use welding of the pail pack is improved. improves. Further, no special material is required for fixing the wire end portion, and no labor is required.
