DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire in a container for welding.

[0002]

The welder of aging such BACKGROUND OF INVENTION Problems to be Solved] There is a need for a lightweight wire (less than 10 kg), also those wound conventional plastic spool or the like, of industrial waste In terms of resource recovery, its treatment has become a social problem.

[0003] If these problems can be solved, the present invention can be applied in a wide range such as welding at a high place or a narrow place where the welding wire must be transported manually.

Conventionally, a wound body S as shown in FIGS. 1 and 2 has been widely used as a storage body for a lightweight welding wire. That is, the winding body S is formed by winding the welding wire W on the body 1a of the bobbin 1 made of plastic, iron, fiberboard, or the like.
After the winding end is locked in a groove, a hole, or the like of the flange portion 1b, the whole is covered with a moisture-proof material, and further provided in a corrugated cardboard 3 or the like. FIG. 2 shows an example of the bobbin 1 and a state where the welding wire W is wound around the bobbin 1.

[0005] In the case of these storage methods, it is necessary to always consider the treatment of waste such as plastic. On the other hand, as a coil-wound welding wire, a wire having a diameter of 2.0 mmφ or more has been put to practical use. However, a thin wire having a diameter of less than 2.0 mmφ has not been put into practical use due to the occurrence of coil loosening and entanglement.

The present invention has been made in view of the above circumstances, and has as its object to provide a welding container-containing wire in which a small-diameter wire is lighter than a conventional one and is stored so as not to cause trouble during use. It is the purpose.

[0007]

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, it has been found that a wire having a diameter of 1.6 mmφ or less usually maintains wire linearity at the time of welding and prevents dispersion at the time of feeding. Because of the simplicity of setting to the welding feeder, it was wound on a spool (spool) made of plastic or the like, but these reels were eliminated, and a cylinder having an inner cylinder, an outer cylinder, and a bottom plate By storing in a container in a predetermined manner,
The present inventor has found that it is possible to restrain and wrap the wire, and has completed the present invention.

[0008] That is, the present invention relates to a container having no reel.
In a welding wire wound in a coil shape without binding, the inner diameter of the outer cylinder is 100 to 300 mmφ, and the inner diameter of the coil is 50 to 250 mmφ in a cylindrical container having a height of 20 to 200 mm having an inner cylinder and a bottom. 0.6-1.6mm
The gist of the present invention is a wire in a welding container, wherein 1 to 10 kg of a small-diameter wire having a diameter of φ is stored and the outer cylinder is made of a resin film.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

The reasons for limiting the wire diameter, the coil weight, the shape and the size of the container, and the like in the present invention are as follows.

Wire diameter: 0.6 to 1.6 mmφ The wire diameter of the narrow wire targeted in the present invention is :
The range is 0.6 to 1.6 mmφ. Dispersion and entanglement during use (welding) are a problem with small-diameter wires, particularly with small-diameter wires of 1.6 mmφ or less. Therefore, the upper limit of the wire diameter is set to 1.6 mmφ. On the other hand, the lower limit of the wire diameter is 0.6 mmφ as a value that can be produced on an industrial basis.

[0012] 1 coil weight: 1~10kg 1 weight is too small for the weight of the coil is less than 1kg, it is not practical will be the frequency of the coil exchange is too much. On the other hand, 10
If it exceeds kg, the weight becomes too large, and handling by humans becomes a problem as in the conventional case. In addition, regarding the coil single weight, in the case of a thin wire, if it exceeds 10 kg,
Wire entanglement and entanglement frequently occur, wire feedability,
If it does, it will lead to defects in the weld. For this reason, the unit weight of the coil is set to 1 kg or more and 10 kg or less.

Coil inner diameter: 50 to 250 mmφ In order to obtain good wire feedability and straightness, the coil inner diameter (see FIG. 3A) must be 50 mmφ or more.
However, if the inner diameter of the coil exceeds 250 mmφ, the winding shape of the coil itself becomes large, and the coil cannot be miniaturized, which is not preferable.
Therefore, the inner diameter of the coil is not less than 50 mmφ and not more than 250 mmφ.

The inner wall diameter of the outer cylinder of the cylindrical container: 100 to 300
If the diameter of the inner wall of the mmφ outer cylinder (see FIG. 3B) is too small, the wire stacking height becomes large compared to the wire stacking width, and the change in the pull-out condition (height direction) increases with the use of the wire. Entanglement and the like easily occur. Therefore, the inner wall diameter is set to 100 mm or more. However, if the inner wall diameter exceeds 300 mm, the coil shape becomes large, and the size cannot be reduced. Therefore, the inner wall diameter of the outer cylinder is set to 100 mm or more and 300 mm or less.

Cylindrical container height: 20 to 200 mm If the height of the cylindrical container (see H in FIG. 3) is too small, the coil shape becomes large and the size cannot be reduced. Therefore, the height is set to 20 mm or more. However, when the height exceeds 200 mm, the wire stacking height becomes larger than the wire stacking width,
With the use of the wire, the change of the pull-out condition (height direction) becomes large, and the wire is easily entangled. Therefore, the height H of the cylindrical container is set to 20 mm or more and 200 mm or less.

As described above, the cylindrical container of the present invention is provided with the outer cylinder having a predetermined size and shape.
The present invention is characterized in that an inner cylinder is provided in a cylindrical container. For example, as shown in FIG. 3, the cylindrical container 4 has an outer cylinder 5, an inner cylinder 6, and a bottom 7, and the inner cylinder 6
It is provided in the center of a hollow cylindrical container 4. In that case,
The hollow portion of the inner cylinder 6 can be fitted to a cylindrical jig (a columnar portion provided at the center of the wire support base) (a hatched portion in the drawing) provided in the wire feeding device when a wire is used. Is preferred.

The cylindrical container may be formed of an appropriate material. For example, an outer cylinder made of plastic or a waterproof board,
The inner cylinder and the bottom are formed as a one-piece mold. It is desirable that the height of the inner cylinder is equal to or lower than the height of the outer cylinder. Further, as shown in FIG. 4, a hole 6 'may be formed in the upper part of the inner cylinder 6, and a columnar portion (a dotted line in the figure) of a wire support of the wire feeder may be inserted into the hole 6'. . It is also possible to seal the upper surface of the container with a rust preventive film or the like, peel off the rust preventive film at the time of use, and set the container on a wire feeding device.

FIGS. 5 to 8 show an example of the structure of the wire in a welding container of the present invention.

FIG. 5 shows a container 4 in which an outer tube 5, a bottom plate 7, and an inner tube 6 are integrally formed of plastic or a waterproof board.
The rust prevention film 8 is heat-sealed or glued on the upper surface to prevent rust of the wire during storage. Further, the inner wall of the outer cylinder and the outer wall of the inner cylinder are formed in a tapered shape extending upward, and the taper of the inner cylinder 6 allows the wire to be more smoothly pulled out. Further, since the position of the wire W is regulated by the outer cylinder 5 and the inner cylinder 6, it is possible to prevent the wire from being disturbed during transportation, wire withdrawal, and the like. Also, by tapering the inner cylinder 6 and the outer cylinder 5,
During wire production, the wire can be smoothly dropped into the container.

FIG. 6 shows a structure in which the bottom plate (disc) 7 and the inner cylinder 6 of the container 4 are made of plastic or cardboard, and the whole is covered with a resin film 9 such as a waterproof (moisture-permeable) shrink film. That is, the outer cylinder 5 is made of a film. According to this configuration, the wire W is regulated by the film 9 (outer cylinder) and the inner cylinder 6 such as a plastic plate, and the regulation of the wire is more reliable than in the configuration of FIG. Also, the manufacturing cost can be reduced.

FIG. 7 shows an example in which the entire container is covered with a rust-preventive film 8, in which the inner cylinder, the outer cylinder and the bottom are made of a rust-preventive film. is there. According to this configuration, the manufacturing cost is low, and the regulation of the wire is also ensured. In addition, as shown in the figure, when a disc-shaped cardboard or plastic plate having a certain rigidity is used instead of the rust-preventive film heat-sealed on the upper surface, the rigidity of the wire in the container is increased, and the handling is easy. Become.

As a modification of the configuration shown in FIG.
As shown in FIG. 8, the entire wire may be covered with a rust-preventive film 8. In this case, the wire is sealed with a rust-preventive film so that it wraps around the wire.
Since is in a hollow state, it can be set as it is in the wire feeding device.

Next, an embodiment of the present invention will be described.
