BACKGROUND OF THE INVENTION
The present invention relates to a welding wire storage container and a container-containing welding wire for storing a solid wire or a flux-cored wire (FCW) in a wound state, and in particular, moisture and moisture are prevented from entering from outside air. The present invention relates to a welding wire storage container and a container-containing welding wire.
[0002]
[Prior art]
A conventional large-capacity container for storing welding wires (hereinafter referred to as a pack) has a resin-coated inner surface of a bottomed cylindrical container body that stores a coiled welding wire with its axial direction vertical. The upper end opening of the container body is covered with a metal lid, and the boundary between the container body and the lid is sealed with a seal made of rubber or the like to prevent intrusion of moisture and moisture from the outside air. It was. In addition, the bottomed cylindrical main body of the pack is reinforced by a ring-shaped metal member at the lower end and the upper end of the main body.
[0003]
Further, the used pack may be repeatedly used for storing the welding wire, but is discarded after being used a predetermined number of times. At the time of disposal, it is necessary to separate the ring-shaped metal member and the lid of the pack body from the body, or it is necessary to treat the whole as industrial waste without separation.
[0004]
[Problems to be solved by the invention]
However, in this way, the conventional pack needs to be separated or processed as industrial waste, and there is a problem that the disposal after use is complicated.
[0005]
In order to solve this problem, it is effective to use paper whose collection and recycling route is established as waste as the material of the pack. That is, if the welding wire storage container is entirely made of paper such as corrugated cardboard, it can be easily recovered at the time of disposal after use and regenerated as a paper product. Moreover, since it is easy to discard, the pack can be used only once for storing and transporting the welding wire, and after the welding wire stored therein is exhausted, the pack can be discarded. Thereby, the useless conveyance cost for returning the used pack to the welding wire manufacturing factory in an empty state can be omitted.
[0006]
However, paper packs are less susceptible to moisture and moisture from the outside air than conventional packs, and oxidation during storage of the welding wire is a problem.
[0007]
The present invention has been made in view of such a problem, and is capable of preventing intrusion of moisture and moisture from the outside air, and enables the storage of the welding wire for a long period of time and the container-containing welding wire. The purpose is to provide.
[0008]
[Means for Solving the Problems]
A welding wire storage container according to the present invention includes a paper-made bottomed cylindrical outer cylinder, a paper-made cylindrical inner cylinder inserted inside the outer cylinder, and the inner side inside the outer cylinder. A bag made of a resin film disposed so as to wrap the cylinder, and a pair of openings provided in the outer cylinder that pass between the outer cylinder and the inner cylinder, and are connected to both ends of the outer outlet portion. And a string-like support body provided with a grip portion for gripping with a hand.
[0009]
In this welding wire storage container, the bag preferably contains a vaporizable rust inhibitor. Specifically, for example, the vaporizable rust inhibitor is applied to the inner surface of the bag.
[0010]
Or it is preferable to have the sheet | seat containing the vaporizable rust preventive arrange | positioned on the welding wire coil accommodated. Specifically, for example, the vaporizable rust preventive agent is applied to the lower surface of the sheet.
[0011]
The vaporizable rust inhibitor contains, for example, dicyclohexylamine nitrite (hereinafter referred to as DICHAN) or diisopropylamine nitrite (hereinafter referred to as DIPAN), and the bag is made of, for example, polyethylene or polyvinyl chloride. It is made.
[0012]
The welding wire storage container preferably has a paper lid that is crowned on the upper edge of the outer cylinder. The inner cylinder has a paper pedestal at the bottom thereof, and a core body arranged coaxially with the outer cylinder and the inner cylinder can be provided at the center of the pedestal. Furthermore, it is preferable that the resin film which comprises the said bag has a thickness of 60 micrometers or more. And as for the said outer cylinder and an inner cylinder, each side wall makes a square cylinder shape, for example. Thus, by making it a square cylinder shape, it becomes easy to assemble an outer cylinder and an inner cylinder from one sheet | seat, and it becomes easy to fold after use.
[0013]
In the welding wire containing a container according to the present invention, a coiled welding wire is stored in the welding wire storage container according to the present invention with its axial direction coinciding with the axial direction of the outer cylinder and the inner cylinder, The opening of the bag is tightened and the welding wire is sealed in the bag.
[0014]
It is preferable that the outer wire of the container is wrapped with a resin film outer bag, or the outer tube is wound around a resin film band.
[0015]
The outer cylinder is made of paper such as corrugated cardboard, and the cardboard can be bent and formed into a bottomed cylindrical shape. The inner cylinder is made of paper such as corrugated cardboard like the outer cylinder, and the corrugated cardboard is made of cylinder. It can be formed by rounding into a shape. In addition, as the resin film, for example, a material having excellent moisture resistance, waterproofness and water repellency, such as polyethylene or polyvinyl chloride, can be used, and a single layer or multilayer structure can be used.
[0016]
In the present invention, the coil-shaped welding wire is accommodated in the inner cylinder, and further, the welding wire is accommodated in a resin film bag together with the inner cylinder, and the welding wire is tightened by tightening the opening end of the bag. Sealed in a resin film bag. Thereby, it is possible to prevent moisture and moisture from entering the periphery of the welding wire. Furthermore, the outside of the outer cylinder can be further reliably prevented from entering the periphery of the welding wire by wrapping it with a bag made of a resin film or winding it with a belt. It is possible to prevent deterioration of the strength of the paper (cardboard) due to water wetting during transportation.
[0017]
And in this invention, since the container is shape | molded with paper, such as corrugated cardboard, the disposal is easy and it can put on a collection | recovery and reproduction | regeneration route, and can recycle.
[0018]
By erecting the core body coaxially with the inner cylinder and the outer cylinder at the center of the bottom of the inner cylinder, the coiled wire can be easily pulled out from the container when the coil of the welding wire is used. The pack shape differs between the flux-cored wire and the solid wire, the core is often used for the solid wire, and the core is often not used for the flux-cored wire. In the case of a wire having a large elastic deformation resistance, such as a solid wire, entanglement tends to occur when the wire is pulled out of the container. The core body is used to prevent the entanglement when the wire is pulled out.
[0019]
In the present invention, the double structure of the pack body is used, and a resin having a single layer or a multilayer structure, which is a material excellent in moisture resistance, waterproofness and water repellency such as polyethylene or polyvinyl chloride between the double structures. By providing a film-made film and the resin-made film having a bag structure, it is possible to prevent moisture and moisture from entering from the outside air around the welding wire. The thickness of the resin film constituting the bag is preferably 60 μm or more. When the thickness of the resin film is less than 60 μm, it is easy to tear during handling and the original purpose cannot be achieved. Further, the paper constituting the outer cylinder and the inner cylinder is preferably cardboard in terms of strength and handleability.
[0020]

The base 13 and the core body 14 are also paper products such as cardboard.
[0023]
The lid 16 has a shape in which a flange extends vertically from each edge of a regular octagonal plate, and each flange has a shape that fits the outer cylinder 11 while contacting the outer surface of the outer cylinder 11. Thereby, the cover 16 is crowned by the upper end opening of the outer cylinder 11. The lid 16 is provided with a pair of ring-shaped elastic members 37 at the lower edges of a pair of opposed flanges. The outer cylinder 11 is provided with a pair of locking pieces 23 at positions that align with the elastic members 37 when the cover 16 is crowned. The locking piece 23 is a triangular small piece connecting a pair of small-diameter holes 22 formed at an upper position and a large-diameter hole 21 formed at a lower position, and is a pair of small-diameter holes 22. And the large-diameter hole 21 are cut so that a line connecting the pair of small-diameter holes 22 can be bent. The elastic member 37 can be locked by the locking piece 23 when the locking piece 23 is closed, and the locking of the elastic member 37 can be released by lifting the locking piece 23. The elastic member 37 is, for example, a rubber band. The lid 16 is also a paper product such as cardboard.
[0024]
A pair of holes 20 are formed in the upper portion of a pair of opposing surfaces of the outer cylinder 11, and a belt 15 disposed along the inner surface of the outer cylinder is connected to the outer cylinder via the holes 20. 11 and is fixed to the belt 15 so that both ends thereof are folded back outside the outer cylinder 11 to form a ring shape. A grip portion 35 for gripping with a hand is constituted by the ring-shaped portion. This string-like support is located between the bottomed cylindrical outer cylinder and the inner cylinder, so that it can not only avoid contact with the wire directly, but also when lifting the gripping part, The shape can be maintained.
[0025]
The bag 50 is formed of a resin film, has a size that encloses the inner cylinder 12 and is disposed inside the outer cylinder 11. The thickness of the bag 50 is preferably 60 μm or more in order to prevent rupture or cutting during assembly work. Moreover, the resin film which comprises this bag 50 is a thing of the material excellent in moisture resistance, waterproofness, and water repellency, such as polyethylene or a polyvinyl chloride, for example, and this can be used as 1 layer or a multilayer structure. it can. In the case of a multilayer structure, the overall thickness is preferably 60 μm or more.
[0026]
Next, the operation of the welding wire storage container and the container-containing welding wire configured as described above will be described. As shown in FIG. 1 and the like, with the belt 15 placed on the inner side surface and the inner bottom surface of the outer cylinder 11, the resin film bag 50 is placed in the outer cylinder with the gripping part 35 led out from the hole 20. Further, the inner cylinder 12 is inserted into the outer cylinder 11, and the pedestal 13 is pushed into the inner cylinder 12 and inserted to the lower end of the inner cylinder 12. Thereby, the container 10 is assembled in a state where the bag 50 made of a resin film is interposed between the outer cylinder 11 and the inner cylinder 12, and the container 10 is grasped and conveyed to the welding wire production line. .
[0027]
In the welding wire production line, as shown in FIG. 4, the produced welding wire 38 is discharged from the winding device 39 into the container, and the welding wire 38 coming out of the winding device 39 is wound. When the device 39 rotates around the center of the inner cylinder 12, the apparatus 39 is spirally dropped into the inner cylinder 12. Thereby, the coil-shaped welding wire 38 is accommodated in the inner cylinder 12.
[0028]
Thereafter, the upper portion of the bag 50 is tightened to seal the welding wire 38 together with the inner cylinder 12 and the pedestal 13 in the bag 50. Then, as shown in FIG. 6, the lid 16 is crowned on the outer cylinder 11, each engagement piece 23 is bent to the outside of the outer cylinder 11, and a pair of elastic members 37 are respectively provided on the back side of the engagement piece 23. The elastic members 37 are engaged with the engagement pieces 23 through the small-diameter holes 22 by returning the engagement pieces 23 to the original positions. In this way, the lid 16 is fixed to the outer cylinder 11.
[0029]
This container with welding wire can be transported by gripping and lifting the grip portion 35. The weight of the welding wire is supported by the belt 15 provided with the grip portion 35, and the weight of the welding wire is not substantially applied to the outer cylinder 11, the inner cylinder 12, the pedestal 13, and the bag 50. Therefore, the outer casing made of corrugated board is not broken by the weight of the welding wire. In addition, the core body 14 is inserted in the center of a wire coil at the time of use of a welding wire as needed. Thereby, it is possible to prevent the wire from being tangled when the wire is pulled out. In this case, the core body 14 is inserted into the hole 31 of the pedestal 13 as shown in FIGS. 2 and 3 (however, these figures are not those when using wires, but merely the core body 14 and the pedestal. 13 is used only to explain the relationship with 13).
[0030]
In the present invention, since the welding wire is sealed in the bag 50, it is possible to prevent moisture and moisture from entering from the outside into the peripheral portion of the welding wire 38, and the welding wire 38 is waterproofed for a long period of time. And in a moisture and moisture proof environment. The used container 10 is discarded as a paper product after removing the resin film bag 50 and the belt 15. When the container is discarded, the bag 50 and the belt 15 can be easily removed by simply removing the inner cylinder 12 from the outer cylinder 11, and the removing operation is easy. Moreover, the container after removing the bag 50 and the belt 15 can be put on a market recovery and recycling route as a corrugated cardboard product, and is extremely easy to dispose of.
[0031]
Note that the shape of the container is not limited to a regular octagonal rectangular tube, but may be a polygonal shape. Thus, by making a container into a square cylinder shape, the outer cylinder, the inner cylinder, etc. which comprise a container at the time of disposal can be easily folded, and conveyance of a waste material becomes easy. However, the present invention is not limited to this. For example, as shown in FIGS. 7 and 8, the container may be formed in a cylindrical shape.
[0032]
Further, as shown in FIG. 7 (a), after covering a cylindrical outer cylinder 111 with a disk-shaped lid 116 with a flange, the whole is covered (covered) with a bag 100 made of a resin film. Thus, it is possible to prevent the container 10 from getting wet with rain water or the like during transportation of the container-containing wire, and it is possible to prevent the strength of the container from deteriorating due to the wetness of the paper container such as cardboard with water.
[0033]
The packaging of the entire container with the resin film may be performed by winding a belt-like sheet 101 made of a resin film around the outer cylinder 111 as shown in FIG.
[0034]
Further, as shown in FIG. 8A, a resin film sheet 102 is stacked on the pallet 103, and a plurality of containers of two or three or more are placed on the sheet 102, and FIG. As shown in FIG. 3, a plurality of containers can be simultaneously covered by covering all the containers together with the sheet 102.
[0035]
Next, a second embodiment of the present invention will be described. In the present embodiment, the bag 50 includes a vaporizable rust preventive agent. This vaporizable rust preventive agent can be added to the bag 50 by kneading the vaporizable rust preventive agent into the film when the resin film constituting the bag 50 is formed. Moreover, after creating the bag 50 with a resin film, the inner surface of the bag 50 may be coated with a vaporizable rust inhibitor.
[0036]
When a vaporizable rust inhibitor is applied to the inner surface of the bag 50, the vaporizable rust inhibitor may be applied to the entire inner surface of the bag 50, for example, as shown in FIGS. 9 (a) and 9 (b). Thus, a vaporizable rust inhibitor may be applied locally. FIG. 9 (a) shows a coating with a vaporizable rust inhibitor in a number of parallel oblique stripe patterns, and FIG. 9 (b) shows a coating with a vaporizable rust inhibitor in a lattice pattern.
[0037]
In this case, examples of the vaporizable rust preventive include DICHAN and DIPAN, and these can be used alone or in combination.
[0038]
When the resin film bag 50 is disposed between the paper outer cylinder 11 and the inner cylinder 12 as in the embodiment shown in FIG. 1, it is possible to reliably prevent moisture and moisture from entering from the outside air. However, since the inner cylinder 12 inside the bag 50 is made of paper, the moisture held in the paper and the moisture in the atmosphere when the coil of the welding wire is stored in the container are due to a sudden drop in temperature. Condensation may cause rust on the welding wire. In order to prevent the occurrence of rust, it is conceivable to put a bag-containing rust preventive into the container, but the rust preventive put into the container is present at the bottom of the container. For this reason, the antirust effect cannot be obtained for the upper welding wire coil in the container. In addition, the worker may forget to put in the rust preventive agent in the bag.
[0039]
However, as in the second embodiment, the bag 50 itself contains a vaporizable rust preventive agent, or by applying a vaporizable rust preventive agent to the inner surface of the bag 50, the bag 50 itself or the inner surface of the bag 50. The rust inhibitor evaporated from the coating layer is filled in the container and uniformly exerts a rust preventive effect on the welding wire coil in the container. Thereby, the antirust effect is sufficiently obtained up to the upper coil portion in the container. Moreover, as long as this bag is used, the rust preventive is reliably supplied into the container. In addition, in this 2nd Example, you may use together injection | throwing-in of a bag-containing antirust agent.
[0040]
When the bag 50 contains a vaporizable rust preventive, a plurality of holes 62 and 63 are formed in the inner cylinder 12 disposed inside the bag 50 as shown in FIGS. 10 (a) and 10 (b). It is preferable to do. The holes 62 and 63 may not be circular holes. FIG. 10A shows a case where relatively large holes 62 are provided, and FIG. 10B shows a case where many relatively small holes 63 are provided. Thus, by providing the holes 62 and 63 to such an extent that the strength of the inner cylinder 12 is not impaired, the rust preventive gas emitted from the bag 50 can easily penetrate the inner cylinder 12 and reach the internal welding wire coil.
[0041]
Next, a third embodiment of the present invention will be described. In the third embodiment, a sheet containing a vaporizable rust inhibitor is disposed at the upper part in the container. This sheet is, for example, a disk as shown in FIGS. 11 (a) and 11 (b), and the sheet 64 shown in FIG. 11 (a) is coated with a vaporizable rust inhibitor in a parallel diagonal pattern. The sheet 65 shown in FIG. 11B is obtained by applying a vaporizable rust inhibitor in a lattice pattern. The sheet 64, 65 is placed on the upper part of the container in which the welding wire coil is housed, that is, on the coil in the container, with the surface coated with the vaporizable rust preventive agent facing downward. In the case where the core body 14 is provided, the central portions of the sheets 64 and 65 are rounded and the core body 14 is inserted to be placed on the coil.
[0042]
The sheet having the vaporizable rust preventive agent is not limited to the application of the pattern as shown in FIGS. 11A and 11B, and the vaporizable rust preventive agent may be applied to the entire surface. May be added to the sheet by kneading the vaporizable rust inhibitor into the sheet when the resin sheet is produced. Examples of the vaporizable rust preventive include the above-mentioned DICHAN or DIPAN. Moreover, as a sheet | seat which has a vaporizable rust preventive agent, not only resin but the paper may be sufficient. Furthermore, the sheet is not limited to a disk shape.
[0043]
In the third embodiment, as in the second embodiment, the gas of the vaporizable rust preventive agent is generated from the sheet, and the periphery of the welding wire coil in the container is filled with the rust preventive agent. Rust prevention effect is obtained.
[0044]
【Example】
Hereinafter, the effect of the Example of this invention is demonstrated compared with the comparative example which remove | deviates from the scope of the present invention. FIG. 12 shows the humidity, temperature and dew point temperature of the test environment. The welding wire was left in this test environment for 3 months. Table 1 below shows the material of the bag, the presence or absence of a rust preventive agent for the bag, and the thickness of the bag. This bag was used to package a coil of welding wire. In this case, in the column “workability of process” in Table 1, “good workability” is indicated by “◯”, and when the bag is torn and torn during the work, “Δ” is indicated. The “Hygroscopic resistance” column is indicated by ○ when the rate of increase in moisture (%) of the wire before and after the test is less than 10%, Δ when 10% or more and less than 30%, and × when 30% or more. . The rate of increase in the moisture content of the wire before and after the test is expressed as (amount of increase in wire moisture before and after the test) / (amount of wire moisture before the test) × 100. Furthermore, “rust generation status” is indicated by “◯” when no rust is generated, “△” when a slight rust is generated but not resulting in a welding defect, and “×” when rust is generated.
[0045]
In Table 1, “PE” is polyethylene, and “PVC” is polyvinyl chloride. As for the welding wire, the flux-cored wire is JIS Z3313 YFW-C50DR, and the solid wire is JIS Z3312 YGW11. And moisture absorption resistance was evaluated with the flux-cored wire, and the rust occurrence status was evaluated with the flux-cored wire and the solid wire (both without plating and with plating). The octagonal pack shown in FIG. 5 was used.
[0046]
[Table 1]

[0047]
As shown in Table 1, since Comparative Example 1 does not use a bag, the wire has poor moisture absorption resistance and rust generation. In Comparative Examples 2 and 3, bags were used, but since the material was made of paper, the moisture-proof effect was not seen, and rust was generated as in Comparative Example 1. Since Examples 4 to 6, 12, and 13 use resin films, rust generation is better than Comparative Examples 1 to 3. Examples 7 to 11 and 14 are excellent in moisture absorption resistance because the thickness of the resin film is as thick as 60 μm or more. In addition, since Examples 8, 10 and 11 use rust preventive sheets, and Examples 7 and 11 use rust preventive bags, the moisture absorption resistance and rust generation status are even more excellent. there were.
[0048]
【The invention's effect】
As described above in detail, according to the present invention, the coiled welding wire is accommodated in the inner cylinder, the welding wire is covered with the inner cylinder together with the resin film bag, and the opening end of the bag is tightened. Thus, the welding wire is sealed in the bag of the resin film, so that moisture and moisture can be prevented from entering the periphery of the welding wire, and the welding wire can be stored for a long time. In particular, when the bag contains a vaporizable rust preventive, or by placing a sheet containing the vaporizable rust preventive on the top of the container, the welding wire in the bag has an even more uniform rust preventive effect. be able to.
[0049]
Furthermore, by wrapping the entire container with a bag made of a resin film, or winding it with a belt-like sheet and covering the entire container, the deterioration of the strength of the paper (cardboard) container due to water wetting during transportation is prevented. Can do.
[0050]
And in this invention, since the container is shape | molded with paper, such as corrugated cardboard, the disposal is easy and it can recycle easily on the collection | recovery and reproduction | regeneration route of a market.
[0051]
Moreover, the entanglement at the time of use can be prevented by erecting a core body coaxially with the said inner cylinder and an outer cylinder in the center of the bottom part of an inner cylinder.
