Description

  The present invention relates to a welding wire storage pack for coaxially storing a welding wire wound in a coil shape in a bottomed cylindrical container, and in particular, welding capable of improving the coil holding state of the welding wire. The present invention relates to a wire storage pack.

  The welding wire is wound in a coil shape, then stored in a storage container, and conveyed to the user as a storage pack-containing wire.

  FIG. 6 is a perspective view showing a conventional welding wire storage pack. FIG. 7 is a perspective view of the conventional welding wire storage pack, and FIG. 7 is a perspective view of the conventional welding wire storage pack. FIG. FIG. 8 is an enlarged perspective view showing the first and second pressing frames. A cylindrical container 1 with a bottom is disposed with its opening facing upward, and a coil of a welding wire (not visible on the drawing) is placed in the container 1 with its axial direction vertical, that is, the container 1 and is stored coaxially (Patent Document 1).

  A presser plate 2 is placed on the upper end portion (one end portion in the axial direction) of the welding wire coil, and on the presser plate 2, first and second presser frames 3 and 4 each having a rectangular tube shape. Has been placed. Each of the presser frames 3 and 4 has a rectangular tube shape in which each side length is equal to each other, and the second presser frame 4 has a slightly larger side length than the first presser frame 3, A second pressing frame 4 is externally fitted to the pressing frame 3. These first and second pressing frames 3 and 4 are both made of cardboard.

  The second pressing frame 4 is arranged so that the lower end thereof is in contact with the pressing plate 2. The second pressing frame 4 has a wide rubber band 5 as an elastic member wound around the four corner portions thereof. That is, as shown in FIG. 8, notches 7 are formed from the respective corners of the second pressing frame 4 at two equidistant positions along the upper edge of the second presser frame 4 and downward from the upper edge. 5 is provided to be locked to the corner portion and the notch 7. Thereby, the rubber band 5 is spanned between the two notches 7 at each corner portion of the second pressing frame 4, and the rubber band 5 is surrounded by the second pressing frame 4 at the bridging portion. Is in the space.

  On the other hand, the first presser frame 3 is formed with notches 8 that engage with the stretched portions of the rubber band 5 at two locations on the lower edge of each corner portion.

  In the conventional storage pack configured as described above, the second pressing frame 4 is placed on the pressing plate 2 on the coil of the welding wire, and the first pressing frame 3 is placed on the second pressing frame 4. The notch 8 is engaged with the spanned portion of the rubber band 5. Then, as shown in FIG. 7, the lid 6 of the storage pack is placed on the first pressing frame 3, the lid 6 is pressed toward the container 1, and the lid 6 is attached to the upper edge of the container 1. .

  However, in the above-described prior art, the coil of the welding wire is pressed into the container 1 by the elastic force of the rubber band 5 stretched around the four corners of the second presser frame 4 made of corrugated cardboard. Due to the reaction force of the pressing stress, a stress acts on the first pressing frame 3 and the second pressing frame 4 in the coil axial direction, and further, this is applied to the four corners of the second pressing frame 4. Stress acts in the direction of crushing the corners. For this reason, there exists a problem that the lifetime of the 1st and 2nd holding frames 3 and 4 is short. In addition, by firmly fixing the coil of the welding wire in the container 1, it is possible to reliably prevent the coil from violating at the time of conveyance, but it is necessary to use a rubber band having a strong elastic force, The corners of the second presser frame 4 are more easily crushed, which causes a problem. Furthermore, even when the coil of the welding wire is increased in size and weight, it is necessary to increase the elastic force of the rubber band in order to hold such a coil. In this case, the rubber band mounting portion becomes more easily crushed.

  The present invention has been made in view of such a problem, and is capable of reliably holding the coil and collapsing the corrugated cardboard at an extremely low cost even under demands for an increase in the size and weight of the welding wire coil. It is an object of the present invention to provide a storage pack for welding wires that can prevent the above-described problem.

A welding wire coil in the container 1 is formed by fitting the first pressing frame 3 into the second pressing frame 14. It is a perspective view which shows the state mounted on the top. FIG. 5 is a perspective view showing a state where a container lid is to be attached. The container 1 has a bottomed cylindrical shape, and a lid 6 is fixed to the opening. The container 1 is arranged with its opening upward, and a coil of a welding wire (not visible on the drawing) is placed in the container 1 so that its axial direction is vertical and coaxial with the container 1. It is stored.

  A presser plate 2 is placed on the upper end portion (one end portion in the axial direction) of the welding wire coil, and the first and second presser frames 3 and 14 having a rectangular tube shape are placed on the presser plate 2. Has been placed. Each of the presser frames 3 and 14 has a rectangular tube shape in which each side length is equal to each other. The side length of the second presser frame 14 is slightly larger than that of the first presser frame 3. A second presser frame 14 is externally fitted to the outer periphery. These first and second pressing frames 3 and 14 are both made of cardboard.

  The first pressing frame 3 has a rectangular tube shape without a bottom and a top plate, but the side surface is folded at the lower end edge to have a double structure. Specifically, a horizontally long rectangular cardboard is folded back twice along a horizontal line, folded along four vertical lines to form a frame, and one end of the butt end is folded at a slight glue margin. The first holding frame 3 is assembled by inserting the marginal part into the folded double structure part of the other butted end.

  The second pressing frame 14 has an outward flange 25 formed at the lower end thereof, and the lower end flange 25 is disposed so as to contact the pressing plate 2 on the coil. Further, the upper end edge of the second pressing frame 14 is folded outward to form a folded portion 24. The second pressing frame 14 has a wide rubber band 15 as an elastic member wound around four corner portions thereof. That is, as shown in FIG. 2, the folded portion 24 of the second pressing frame 14 has a rectangular shape at two positions equidistant from each corner of the second pressing frame 14 along its upper edge. A notch 17 is formed as a hole, and the rubber band 15 is provided to be locked to the corner portion and the notch 17. Accordingly, the rubber band 15 is stretched between the two notches 17 at each corner portion of the second pressing frame 14, and the rubber band 15 is surrounded by the second pressing frame 14 at the spanning portion. Is in the space. In addition, a notch 30 is formed at the end of the folded portion 24 on the corner side of the second pressing frame 14 so as to be notched in the horizontal direction from the end edge, and the rubber band 15 is engaged with the notch 30. As a result, the end portion of the folded portion 24 is allowed to swell slightly outward.

  In the storage pack of the present embodiment configured as described above, as shown in FIG. 3, the first pressing frame 3 is fitted into the second pressing frame 14, and the first pressing frame 3 is attached to the rubber band 15. The second hook frame 14 is latched to the portion spanned. Then, as shown in FIG. 4, the first pressing frame 3 and the second pressing frame 14 are placed on the pressing plate 2 on the coil of the welding wire in the container 1.

As a result, when the storage pack is transported or stored, the coil of the welding wire is violated in the container 1, the surface of the wire is damaged due to this violence, or the winding of the coil of the welding wire is unwound. Is prevented.

  Thus, in the present embodiment, since the rubber band 15 is attached to the folded portion 24 of the second pressing frame 14, the strength of the attachment position of the rubber band 15 is high. For this reason, the coil of the welding wire is increased in size and weight, and it is necessary to use a rubber band 15 that is an elastic member that has a higher elastic coefficient than conventional ones and that has a high tensile strength when the rubber band 15 is stretched. Even if this occurs, it is possible to prevent the rubber rubber 15 from collapsing the mounting position of the rubber band 15 on the second pressing frame 14, thereby extending the life of the first and second pressing frames 3, 14. Further, since the high-strength rubber band 15 can be used, the welding wire coil in the container can be reliably held without being violated.

  In addition, this invention is not restricted to the above-mentioned embodiment, A various modification is possible. For example, in the above-described embodiment, the first and second holding frames so that the second holding frame 14 to which the rubber band 15 as the elastic member is attached contacts the holding plate on the welding wire coil in the container 1. 3 and 14 are arranged on the coil, and the rubber band 15 is pulled by pushing the first pressing frame 3 into the container 1 with the lid 6, but conversely, the first pressing frame 3 is placed in the container 1. The first and second presser frames 3 and 14 are arranged on the coil so as to contact the presser plate on the welding wire, and the second presser frame 14 is pushed into the container 1 with the lid 6 to thereby provide a rubber band. 15 may be in a tensile state.

  Further, as described above, the notch 17 is not a rectangular hole but may be notched so as to be directed downward from the upper end edge of the folded portion 24, as long as the rubber band 15 can be held in a triangular shape. . Further, the elastic member is not limited to the one in which the endless rubber band is locked to the corner portion of the second pressing frame 14, and 1 is provided on both inner surfaces of each corner portion so as to span the corner portion of the second pressing frame 14.
