Description

[Detailed description of the invention] The present invention relates to a welding wire storage container that stores a large amount of welding wire and has a holding member placed on the upper surface of the laminated wire. The structure is such that the welding wire can be drawn out smoothly by forming a section.

A cylindrical container (hereinafter referred to as a pack) is used to store a large amount of welding wire (hereinafter simply referred to as wire) and to continuously draw out and use the wire.

In addition, for such a pack, it is necessary to store the wires in such a way that they can be pulled out without getting tangled, and when pulling out the wires, it is necessary to prevent the layers from being disordered or tangled due to springback, and it is necessary to use various storage means and guide devices. is proposed.

For example, when storing wires, store them in a loop with a diameter smaller than the inner diameter of the pack, and
A method has been proposed in which the center of the loop is eccentrically moved so as to move in a circular manner, and a part where the loops do not overlap, that is, a cylindrical cavity is formed in the center of the pack, and the packs are stacked and stored.

The wire stored in this way forms a flower pattern and can be pulled out smoothly, but in order to prevent the loop from being disturbed during storage and withdrawal, an inner tube is provided in the cylindrical cavity. There are often

The inner cylinder may be fixed to the bottom of the pack or may be formed integrally with the bottom of the pack.

On the other hand, when pulling out wires from such a pack,
Springback of the wire coil can disturb the upper layer coil and cause it to get tangled with the wire being pulled out, so a holding plate or special wire tangle prevention jig is used.

The holding plate is configured to be lowered by its own weight as the weight of the wire decreases, and the wire entanglement jig is placed at the upper part of the inner cylinder.

In addition, various types of holding plates have been proposed to facilitate the drawing out of the wire, and the present applicant has also applied for patents and utility models for these holding plates.

For example, Fig. 1 (partially cutaway diagram) shows a state in which the wire is pulled out from the pack using the latter method. 3, and the laminated wire 4 is housed in the space formed between the outer cylinder 2 and the inner cylinder 3 by the method described above.

2a is a peephole provided on the bottom side of the outer cylinder 2 in order to know the remaining amount of laminated wire.

To draw out wires from such a wire storage pack 1, a lid plate (not shown) of the pack is removed and then a drawing device is attached.

As the drawing device, for example, the one shown at 5 in FIG. 1 is used, and the conical cover 6 replaces the lid plate and is fitted and fixed to the top of the outer cylinder 2, and a wire take-out lower is provided at the top.

The figure shows a flyer 8 rotatably provided inside a conical cover 6, and the take-up wire 4a is fed through a guide hole provided at the tip of the flyer 8.

The flyer 8 is then rotated according to the wire loop.

On the other hand, the take-up wire 4a guided to the flyer 8 is
The wires are separated from the top surface of the stack by untying the loop one by one, but since the wires are rigid, there is a risk of springback and tangles, so a wire guide ring 9 attached to the inner cylinder is used to prevent the wires from springing up. ing.

That is, the one in FIG. 1 is formed as a double ring, and a plurality of support rods 9a are fixed to the nong 9 in the radial direction, and the inner ends of the support rods 9a are each bent downward. It is held at the top of the inner cylinder 3.

When feeding a wire using such a jig, there is no problem if the wire does not spring up (due to springback), but if there is a strong tendency for the wire to spring back due to springback, the wire may be inside the cover 6. It springs up and creates tangles.

In order to reduce such wire jump-up as much as possible, a double guide ring 10 as shown in FIG. 2 (partially cutaway diagram) is used instead of the guide ring 9.

That is, the ring 10 has a lower ring 10 of the same diameter on its lower side.
a, and when supported by the inner cylinder 3, inner rings 10b, 10b are provided at the center and have a diameter that almost matches the outer diameter of the inner cylinder 3, and these are connected by a rod 10C and an L-shaped connecting rod 10d. They are connected in a letter shape and fitted onto the top of the inner cylinder 3.

However, even with such a double guide ring 10, it is not possible to prevent the space through which the wire passes from becoming a place through which the wire jumps up, causing the wire to jump up and become tangled.

All of these guide rings use the outer periphery as the guide edge, and since the wire surface is free (no holding member), the wire tends to spread and it is impossible to completely prevent tangling. It was impossible.

In consideration of this point, it was devised to use a presser plate 11 as shown in FIG. 3 (divided view showing a conventional wire storage container).

That is, the holding plate 11 is made of a relatively lightweight wood or synthetic resin plate, and the outer diameter of the inner cylinder 3 is sized to form gaps 13 and 13a, respectively.

Further, the holding plate 11 is provided with the holding plate 11 to maintain the above-mentioned gap, and as the top surface of the laminated wire 4 descends, the holding plate 11 is attached to the outer cylinder 2.
A plurality of elastic support pieces 12 are arranged so as to slide down along the inner circumferential surface.

The elastic support piece 12 uses its elasticity to hold up the presser plate and also prevents the wire from escaping upward through the gap 13a.

The drawing wire 4a is drawn out from the inner hole of the holding plate 11, that is, the gap 13.

Note that 4b in FIG. 3 shows an example of a wire that protrudes from the gap 13a side due to springback, and since the wire overcomes the contact pressure of the elastic support piece 13 and overcomes the support piece, such a phenomenon will not occur. We have to make sure that there is no such thing.

In addition, in such an inner drawer presser plate 11, since the contact/separation line of the drawer wire 4a is formed by a small diameter circle, the third
When the top surface of the laminated wire 4 is high as shown in the figure, it can be pulled out smoothly, but when the top surface is low as shown in FIG. It gets tangled and makes it impossible to withdraw.

Therefore, in reality, the guide ring 9 described above is provided at the head of the inner cylinder to reduce contact with the wire and to prevent feeding from stopping at the edge of the inner cylinder.

Further, since the presser plate 11 has its lower flat plate portion in contact with the top surface of the laminated wire, when pulling out one loop, it may come into contact with another loop and disturb the loop.

That is, it is difficult to manage the contact pressure, and for example, when the presser plate 11
When distortion occurs, the loop immediately becomes disturbed.

If only the weight of the presser plate is increased in order to prevent these problems, phenomena such as bending of the wire at the rising portion or inability to feed the wire will occur.

The present invention has been developed with these points in mind, and it is an object of the present invention to provide a wire storage pack in which a presser member is placed on the wire, and which satisfies the above-mentioned demands.

However, this invention utilizes a storage pack in which the inner cylinder 3 of the wire storage pack is completely eliminated or is formed only on a part of the bottom side, and the holding member is arranged in an annular shape in approximately the same plane. A member and a frame member surrounding the annular member are disposed, and bridging members are fixedly connected to these members at two or more locations at approximately equal intervals, and a flexible elastic member is attached to the bridging member on the outside of the frame member. It is configured to be attached by a fixing member integral with the bridging member so as to protrude from the bridging member.

The present invention will be explained in detail below based on the drawings, but the drawings show an example of a specific implementation of the present invention, and the present invention is not limited to these illustrated examples, but is constructed in accordance with the spirit described above and below. Even if the shape of the parts is changed or a part of the design is changed, the same implementation is possible.

FIG. 5 is a partially cutaway sketch of the wire storage pack according to the present invention in a state where the wire is being pulled out.

The pressing member 15 is an annular member 16. The frame members 17 are arranged in the same plane, and a portion of their top surfaces are fixedly connected to each other by a bridging plate 18.

The bridging plates 18 can be installed in symmetrical positions that divide the circumference into three equal parts as shown in the figure, or in four places each with nine
They may be fixed at intervals of 0'; in short, at least two or more locations may be fixed at approximately equal intervals.

Note that although the frame member 17 is formed in an annular shape, the frame member 1
7 may simply be formed on the same plane as the shaped member 16 to accommodate the laminated wire 4, and can be freely deformed such as being non-circular, meandering, and bent.

However, in order to make it lightweight, it is recommended that both be circular as shown in the figure.

Further, these members 16 and 17 are made of metal rods and wires, and any appropriate cross-sectional shape can be used regardless of whether they are solid or hollow.

Since these members 16, 17 contact only a portion of the wire, there is less risk that the pull-out loop will disturb other loops, compared to a donut plate that contacts almost the entire surface.

On the other hand, the bridging plate 18 connecting these members is as shown in FIG. 6 (a partially enlarged plan view of FIG. 5) and FIG. 7 (a cross-sectional view in the direction of the cutting line vti-VII arrow in FIG. 6). The annular member 16 and the frame member 17 are connected to each other and are configured as a mounting seat for installing a flexible elastic plate 20.

Further, as the bridging plate 18, a metal plate of an appropriate thickness is welded to the top surfaces of the annular member 16 and the frame member 17. These fixing members are molded onto the bridging plate 18 in advance or fixed with screws.

That is, each bridging plate 18 has a folded gripping piece 19, 19 formed at a certain position on the inside thereof, or is bent into a gate shape using a mold.

Furthermore, if the stopper piece 21 is formed on the center side of the widthwise center of the bridging plate 18, the protruding length of the flexible elastic plate can be easily adjusted.

Although a punched-out protrusion is shown as the restraining piece 21, it may be a suitable folded-back piece or may be provided on the gripping piece 19.

It goes without saying that arranging the bridging members at approximately equal intervals includes arranging each group of a plurality of bridging members at equal intervals.

On the other hand, the flexible resilient plate 20 provided on such a bridging plate 18 is curved as shown in FIG. An elastic member is used that allows the wire to descend and provides a contact pressure that prevents the wire from climbing over the gap 13a, but generally a material of appropriate hardness is selected from rubber or synthetic rubber and attached.

In addition, when attaching, one end side of the elastic plate 20 is held along the above-mentioned stopper piece 21 and the grip piece 19.19 is bent and gripped, or the grip piece 19.19 that has been bent in advance is used to hold the elastic plate 20.
Insert and attach.

If such a mounting method is used, as long as the elastic plates 20 have the same shape and size, the curvature of the elastic plates 20 will be constant when placed in the pack 14, and the elastic plates 20 will be held concentrically by mutual tension. be able to.

Therefore, it is not necessarily necessary to attach elastic plates to all the bridging plates.

8 and 9 show examples in which a folded piece 19 is attached to the bridging plate 18 by welding, and the elastic plate 20 is gripped by the folded piece 19.

FIG. 10 shows an embodiment in which the gripping piece 19a formed on the bridging plate 18 has a different shape, and can be changed to any other suitable shape.

Further, FIG. 11 shows a frame member 17 having a rectangular outer diameter, and bridging plates 18 are provided symmetrically in four directions.

In the wire storage container of the present invention, since the presser member is constructed in this manner, the top surface of the laminated wire is held in pressure contact with the bottom surface of the presser member.

Therefore, there is less risk of the pull-out loop disturbing other loops, and since the flexible elastic plate attached to it is attached to the bridging plate connecting the annular member and the frame member so that the bending position can be regulated, each elastic plate The contact pressure between the wire and the inner surface of the outer cylinder can be made uniform, and it is easy to handle and manufacture, making it an extremely excellent holding member.The wire can be pulled out smoothly and welding work can be streamlined.
