Description

[Detailed description of the invention] The present invention reliably prevents entanglement of the wires due to springback when pulling out welding wires stored in a pail container in the axial direction of the container, making the drawer smoother. , or relates to a wire storage container for preventing wires from flying up during transportation.

When pulling out wires stored in a pail container, it is often experienced that the springback of the wires causes the wires to become tangled, making it difficult or impossible to pull them out.

In order to prevent these difficulties, a floating ring 4 made of a rigid body is placed on top of the wire 3 housed between the outer cylinder 1 and the inner cylinder 2, as shown in FIG. death,
A method of preventing springback by pressing the wire 3 from above, or a similar method as shown in FIG.
A method has been implemented in which a presser ring 5 is fixed to the upper part of the holder to suppress springback.

However, in these methods, since there is a gap between the floating ring 4 and the outer cylinder 1, the wire 3 may jump up from this gap and become difficult to pull out.

Further, in the example shown in FIG. 2, as the wire 3 is drawn out, the gap below the presser ring 5 expands, so that the wire 3 that has sprung back becomes entangled in this portion, causing a drawing failure.

In particular, when welding wires, such as recent welding wires, are stored after being twisted or bent within their elastic limits, the force that tends to spread toward the outer periphery or jump up is quite large.
The above-mentioned difficulties become even more obvious.

The inventors of the present invention focused on the above-mentioned circumstances, and created a storage container that can be pulled out smoothly not only for ordinary wires but also for welding wires that have been twisted or bent, without becoming entangled. We have been conducting intensive studies in anticipation of development.

As a result, in order to prevent the wires from getting entangled, the following steps are required: 1. Even if the amount of wires stored decreases as the wires are pulled out, the wires must be able to be held down from above without any gaps; 2. The wires will bounce upward due to the springback. Since it is going up, there should be no gap between the inner wall of the outer cylinder or the outer wall of the inner cylinder and the holding plate.
It was confirmed.

The present invention was developed based on the above knowledge and after extensive study with the aim of developing a storage container that would satisfy the above requirements.The design consists of an inner tube and an outer tube. A welding wire storage container in which a welding wire is housed in a pail container having a wire holding plate configured as an integral body having an elastic portion that contacts at least one of an outer wall of the content and an inner wall of the outer cylinder. The gist lies in that it is placed on the upper surface of a stack of welding wires.

The configuration and effects of the present invention will be explained below based on the drawings, which are examples. However, the following does not limit the present invention, and the material, shape, etc. may be changed in accordance with the spirit of the above and below. are also possible, and all of them are within the scope of the present technology.

FIG. 3 is a partially cutaway diagram showing how the welding wire 3 is pulled out using the storage container 6 according to the present invention. It is made of an elastic material such as a foamed synthetic resin board such as polyethylene, and a part of its outer periphery is cut out ω', leaving outer periphery protrusions 6a on both sides of the notch ω', which are brought into contact with the inner periphery of the outer cylinder 1. A part of the inner circumferential edge is also formed with a notch 6b' and inner circumferential protrusions 6b on both sides of the notch 6b' so as to be brought into contact with the outer circumferential surface of the inner cylinder 2.

Then, the wire 3 is pulled out through the notch recess 6b' (or the notch recess 6a').

That is, with the presser plate 6 having such a structure, the outer circumferential convex portion 6a is in constant contact with the inner circumferential surface of the outer cylinder 1, and the inner circumferential convex portion 6b is in constant contact with the outer circumferential surface of the inner cylinder 2, and there is no gap between them. Since this is not possible, there is no fear that the wire 3 will jump up above the holding plate 6.

Moreover, the inner and outer peripheral edges of the presser plate 6 have notched recesses 6a'9 and 6b.
Since the elasticity is further enhanced by the formation of ', the remaining convex portions 6a*6b are elastically deformed by the weight of the holding plate 6.

Therefore, as the wire storage height decreases, the holding plate 6 descends smoothly, and the wire 3 is always held from above without any gaps.
There is no risk of causing a failure as shown in Figure 2.

In this example, both the outer protrusion 6a and the inner protrusion 6b are formed so that the wire 3 can be applied regardless of the curl of the wire 3, but the inner protrusion 6b may be omitted depending on the direction of springback. It is also possible to omit the outer circumferential convex portion 6a (when the springback is in the diameter-expanding direction) or omit the outer circumferential convex portion 6a (when the springback is in the diameter-reducing direction).

Note that the notched recesses 5a' and 5b' are provided to increase the elasticity of the inner and outer peripheral edges of the presser plate 6 so that the presser plate 6 can descend smoothly under its own weight, so they exhibit such a function. As long as the width, depth, number, etc. of the slits are not limited, the purpose can be achieved by simply forming a large number of slits in some cases.

Further, for the same purpose, it is also possible to increase the elasticity by making the inner and outer peripheral edges of the presser plate 6 thinner.

However, if it is not possible to secure a pull-out part for the wire 3 in these modifications, a separate wire pull-out hole is provided in the presser plate 6,
Alternatively, it is necessary to form special cutout recesses on the inner and outer peripheral edges for drawing out the wire.

Furthermore, if the presser plate 6 is made of a lightweight material such as foamed resin, there is a risk that it will not be able to descend due to its own weight, but in such a case, for example, as shown in FIG. It is desirable to place and fix the seat 7 so that it descends smoothly.

The inner holding plate 6 is configured as described above, for example, but as is clear from the above purpose, the main purpose is to contact the outer cylinder 1 and/or the inner cylinder 2 of the pail container to prevent the wire 3 from jumping up. In addition, since it is sufficient that the wire 3 descends smoothly under its own weight as the wire 3 decreases, the specific shape and structure can be changed in various ways as long as it has such a function.

For example, FIG. 4 is a plan view showing the presser plate 6 with both the outer circumferential convex part 6a and the inner circumferential convex part 6b left as in FIG. 3, but in addition, as in FIG. Alternatively, as shown in FIG. 6, only the inner peripheral convex portion 6b may be left.

The size and number of these convex portions 6a and 6b are determined by the wire 3.
It may be determined appropriately depending on the winding pattern, springing force, material (particularly elastic force), thickness, etc. of the presser plate 6.

Furthermore, as mentioned above, it is effective to adjust the size and number of the protrusions 6a and 6b as a means of adjusting both the functions of preventing the wire from jumping up and lowering it due to its own weight. , 6b are not particularly limited in shape.

For example, FIGS. 7 to 9 are plan views of main parts showing modifications of the inner protrusion 6b, and FIGS. 10 to 15 are plan views of main parts showing modifications of the outer protrusion 6a, but these modifications are of course not included in the present invention. be.

Of these, Figs. 7.9.10 to 14 show the convex portion 6a,
A space 8 is provided in the portion 6b to further increase the elasticity of the protrusions 6a and 6b, and if these are used, the outer cylinder 1 and the inner cylinder 2
It is recommended as one of the most preferable shapes because even if the dimensions of

The present invention is roughly constructed as described above, and in particular, the holding plate reliably descends as the amount of wire decreases due to drawing out, holds the wire from above at all times, and prevents the wire from jumping up. As a result, entanglement phenomena due to wire springback and the like are reliably prevented, and the wire can be pulled out extremely smoothly.

In addition, this holding plate reliably prevents the wires from jumping out during transportation, so it is also possible to reliably prevent the wires from getting entangled during transportation.
