Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging box for accommodating one or a plurality of coil winding welding wires.

[0002]

2. Description of the Related Art A flux-filled or solid wire welding wire having a diameter of, for example, 0.6 to 2.4 mm for use in arc welding is manufactured in a coil-shaped laminated and wound form. Is done. That is, the welding wire is coiled in a cylindrical shape (donut shape), and its weight is 1 to 5.
20kg, coil inner diameter of 50 to 180mmφ, coil width of about 40 to 100mm are manufactured as one unit.

[0003] This welding wire coil is made of a reel such as a reel or spool (for example, Japanese Patent Application Laid-Open No. 58-10346,
Alternatively, there is a case where the coil is wound using JP-A-62-19646) and a case where the winding frame is removed after the coil is wound and only the wire coil is bound with a binding wire, a wide steel band, a plastic band, or the like. is there.

When using a welding wire coil with a bobbin, the bobbin is connected to a shaft of a wire feeding device of a welding machine, and a welding wire is pulled out from the bobbin and fed to a welding head. If the welding wire coil does not have a bobbin,
Then, the reel is attached to a shaft of a wire feeder after being mounted on a reel such as a screw (for example, JP-A-5-111770 and JP-A-5-200553).

[0005] In either method, the wire must be unwound from the coil so that the welding wire is not tangled. If the shape of the wire coil is lost, entanglement tends to occur. Therefore, the coil-winding welding wire needs to be protected and transported so as not to be deformed. Hitherto, a box made of a corrugated ball has been used as a packaging box for a wire for coil winding welding.

[0006]

However, if the coiled wire is simply stored in the corrugated ball box, the coiled wire is easily moved in the box, and the packaging box made of corrugated ball may be damaged. Or it was easy to cause deformation of the coiled wire for welding.

SUMMARY OF THE INVENTION It is a first object of the present invention to provide a packaging box having a high static stability of a coiled wire.
It is a second object of the present invention to provide a packaging box having high static stability of a coil-wound wire having no winding drum such as a coil.

[0008]

[Means for Solving the Problems]

(1) The packaging box for coil winding welding wire of the present invention has a coil winding welding wire (2) having a coil center line extending in the y direction parallel to a bottom plate (1bm, 1p) having an x, y plane. A packaging box (1) supporting the outer peripheral surface of the coil with a bottom plate (1bm, 1p), which is disposed on the bottom plate (1bm, 1p) and extends in the y direction.
xz cross section is one oblique side perpendicular to the outer peripheral surface of the coil (b1
a, b2a), comprising a pair of movement prevention blocks (1b1, 1b2) facing each other in the x direction with a vertical projection line of the center line onto the bottom plate interposed therebetween. .

For easy understanding, the reference numerals of the corresponding elements in the embodiment shown in the drawings and described later are added for reference in parentheses.

According to this, a wire for coil winding welding
Even if (2) attempts to move (rotate), the movement preventing blocks (1b1, 1b2) have a shape that is similar to that of the vehicle's bollard, so that the movement preventing effect is high. In particular, blocks for preventing movement
(1b1, 1b2) is an oblique side perpendicular to the outer peripheral surface of the coil (2) (b1a, b
2a), which are directed toward the center of the coil, have a strong drag toward the center of the coil, and have a high block strength for preventing coil movement.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION

(2) The movement preventing blocks (1b1, 1b2) are triangular cylinders formed by bending a single step ball plate (1p).
The bending process of the corrugated ball plate is easy, and the manufacturing cost of the block is low.

(3) The block for preventing movement (1b1, 1b2)
Is a triangular cylinder formed by bending both end portions of the bottom plate step ball plate (1p) and connected to the bottom plate (1p). The bending process of the corrugated ball plate is easy, and the manufacturing cost of the block is low. In addition, since the pair of blocks are integral with the bottom plate (1p), no displacement occurs between the blocks.

(4) The block for preventing movement (1b1, 1b2)
Is a double plate at least on one side. The block strength of this double plate portion is high.

(5) The block for preventing movement (1b1, 1b2)
Have a cross section in which the inside of a large triangle is divided into two small triangles by one oblique side (b1a, b2a) perpendicular to the outer peripheral surface of the coil. Since the so-called oblique shape is included in the large triangle, the coil support strength of the block is high.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

Since it is selected, the coil winding welding wire 2 is supported at three points, the weight load on the packaging box 1 is dispersed, and there is no rattling. Block 1b
The position where the outer peripheral surface of the coil-winding welding wire 2 is in contact with the base plate 1p may be set to a height (z direction) such that the lowermost position of the coil-winding welding wire 2 is separated from the bottom plate 1p. The coil winding welding wire 2 is composed of blocks 1b1 and 1b2.
Is hollow supported at two points, so that the stability is high. When the coil winding welding wire 2 is moved (rotated) in the x direction and the blocks 1b1 and 1b2 are pressed, the block 1
Since the compressive strengths of b1 and 1b2 are high, they are not deformed and the prevention of movement is large.

The movement preventing blocks 1b1 and 1b2
Is made of a corrugated ball, so it is cheap and lightweight, and is easy to work. Since the packaging boxes 1 including the movement preventing blocks 1b1 and 1b2 are all made of corrugated balls, there is no particular problem when disposing them as industrial waste.
