  The welding wire storage 1 includes a welding wire storage container 10 that opens vertically upward, and a welding wire 20 that is stored in a spiral (coiled) state inside the welding wire storage container 10. Prepare. Here, as the welding wire 20, a solid wire or a flux-cored wire can be used. However, in this example, it is assumed that a flux-cored wire is used as the welding wire 20. In the following description, the welding wire 20 laminated in a spiral shape may be referred to as a wire coil 40. The welding wire storage container 10 corresponds to a “pail pack” defined in JIS Z 3200: 2005.

First, the configuration of the welding wire storage container 10 will be described.
The welding wire storage container 10 includes a bottom plate 11, an outer cylinder part 12, an inner wall part 13, an inner cylinder support part 14, and two handles 15.

  Of these, the bottom plate 11 has a circular shape and is made of cardboard. Moreover, the outer cylinder part 12 is exhibiting the cylindrical shape, and this is also comprised with the cardboard. And the peripheral part of the baseplate 11 and the lower end part of the outer cylinder part 12 are united by caulking with metal rings (not shown). Thereby, the outer cylinder part 12 is comprised so that it may stand up from the periphery of the baseplate 11. FIG. A metal ring (not shown) is also attached to the upper end portion of the outer cylinder portion 12. And the moistureproof agent for suppressing the penetration | invasion of the water | moisture from the outside is apply | coated to the upper surface of the baseplate 11, and the internal peripheral surface of the outer cylinder part 12. FIG.

  The inner wall portion 13 is provided inside the outer cylinder portion 12 along the inner peripheral surface of the outer cylinder portion 12. In this example, the inner wall portion 13 is provided over the entire inner peripheral surface of the outer cylinder portion 12. Therefore, the inner wall portion 13 also has a cylindrical shape as a whole. In this example, the wire coil 40 is disposed inside the inner wall portion 13. The inner wall portion 13 is made of plastic, and is attached to the outer cylinder portion 12 using an adhesive tape, an adhesive, or the like. Moreover, although the inner wall part 13 has a structure where the some top part which protrudes toward inner side was further connected, the detail is mentioned later.

  Further, the inner cylinder support portion 14 is disposed at the approximate center of the upper surface of the bottom plate 11. When the solid wire is used as the welding wire 20, the inner tube support portion 14 is fitted and supported by a cylindrical inner tube 16 (shown by a two-dot chain line in FIG. 2) which is attached upright inside the wire coil 40. Is for. The inner cylinder support portion 14 has a dish-like shape in which a peripheral portion of a bottom portion having a circular shape rises vertically upward, and is made of metal. And the inner cylinder support part 14 is attached to the baseplate 11 using the adhesive tape, the adhesive agent, etc. FIG. In this example, a flux-cored wire is used as the welding wire 20 and the inner cylinder 16 is not attached.

  Furthermore, the two handles 15 are attached to a portion on the vertically upper side of the outer peripheral surface of the outer cylinder portion 12 so as to face each other. These two handles 15 are made of metal, and are used as handles when the user carries the welding wire storage 1 or the welding wire storage container 10.

Next, the configuration of the wire coil 40 will be described.
The wire coil 40 is disposed in a space above the bottom plate 11 in the welding wire storage container 10 and inside the inner wall portion 13 and outside the inner cylinder support portion 14. And the wire coil 40 is accommodated in the welding wire storage container 10 by filling it so that it may be dropped by applying a twist of approximately 360 ° per turn in a spiral from above the welding wire storage container 10. . Therefore, in the welding wire storage 1, the welding wire 20 is wound in a spiral shape from the lower side to the upper side and stacked, thereby forming the wire coil 40.

  When the above-mentioned welding wire storage 1 is used in a welding apparatus that employs mag welding (including carbon dioxide arc welding) or MIG welding, a conical guide called an arrow hat is located above the welding wire storage 1. (Not shown) is attached. Further, a ring-shaped pressing plate (not shown) is disposed above the wire coil 40 inside the welding wire storage 1.

Subsequently, the inner wall portion 13 provided in the welding wire storage container 10 will be described in more detail.
FIG. 4 is a perspective view showing a configuration example of the inner wall portion 13. FIG. 5 is a front view for explaining a main part of the inner wall portion 13. Here, FIG. 4 has shown the figure which expand | deployed the inner wall part 13 which exhibits cylindrical shape in FIG. 1 in flat form.

  The inner wall portion 13 has a configuration in which a plurality of frame bodies 31 and a plurality of connection bodies 32 are alternately connected. From another viewpoint, the inner wall portion 13 is configured by connecting a plurality of frame bodies 31 by connection bodies 32. Here, each frame body 31 and each connection body 32 each have a vertically long shape extending upward from below in FIG.

  Among these, the frame 31 has a substantially trapezoidal cross section, and includes a bottom surface portion 311, a top surface portion 312, two slope portions 313, and a reinforcing portion 314.

  First, the bottom surface portion 311 serving as the lower bottom is disposed on the side facing the inner peripheral surface of the outer tube portion 12 in the welding wire storage container 10. Further, the upper surface portion 312 serving as the upper bottom is disposed on the side facing the wire coil 40 (welding wire 20) in the welding wire storage container 10. Here, the bottom surface portion 311 and the top surface portion 312 are set in a substantially parallel positional relationship. Further, the one slope portion 313 connects one end side of the bottom surface portion 311 and one end side of the top surface portion 312. Furthermore, the other inclined surface portion 313 connects the other end side of the bottom surface portion 311 and the other end side of the upper surface portion 312. The reinforcing portion 314 connects the central portion of the bottom surface portion 311 and the central portion of the top surface portion 312 in a hollow portion formed inside the bottom surface portion 311, the upper surface portion 312, and the two slope portions 313. Here, in the present embodiment, the bottom surface portion 311 functions as an example of the bottom portion, and the top surface portion 312 functions as an example of the top portion.

  Next, the connection body 32 has a plate-like cross section, and in two adjacent frame bodies 31, one end portion of the bottom surface portion 311 in one frame body 31 (the bottom surface portion 311 and one inclined surface portion 313. And the other end portion of the bottom surface portion 311 in the other frame body 31 (the connection portion between the bottom surface portion 311 and the other inclined surface portion 313). Here, the back surface of each connection body 32 constitutes a surface integrated with the bottom surface portion 311 provided in each frame body 31.

  The inner wall portion 13 of the present embodiment is manufactured by press molding a synthetic resin material. Here, it is desirable that the frame body 31 is made of a thermosetting resin such as an epoxy resin, a polyurethane resin, or a polyester resin. On the other hand, the connection body 32 is preferably composed of a thermoplastic resin such as a vinyl chloride resin, a PP resin, a PE resin, an ABS resin, or a PC resin. That is, in the inner wall portion 13, the frame body 31 may be made of a relatively hard hard synthetic resin, and the connection body 32 may be made of a relatively soft soft synthetic resin.

  Here, in the frame body 31, the circumferential length of the bottom surface portion 311 is the bottom surface width A, the circumferential length of the top surface portion 312 is the top surface width B, and the circumferential length of the slope portion 313 is the slope width C. To do. In addition, the circumferential length of the connection body 32 is defined as a connection width D. Then, in the present embodiment, in the frame 31, the bottom surface width A> the top surface width B, and the top surface width B> the slope surface width C and the bottom surface width A> the slope surface width C. In the present embodiment, in the frame body 31 and the connection body 32, the bottom surface width A> the connection width D, the top surface width B> the connection width D, and the slope width C ≦ the connection width D.

Next, operation | movement of the welding wire storage thing 1 of this Embodiment is demonstrated.
The holding plate and the arrow hat (both not shown) are attached to the welding wire storage article 1 and one end of the welding wire 20 is pulled out from the hole provided at the upper end of the arrow hat. And this welding wire 20 is sent to the torch (not shown) of a welding apparatus. In connection with this, the welding wire 20 wound spirally is sequentially pulled out from the wire coil 40 accommodated in the welding wire storage container 10 in the welding wire storage article 1.

  Now, the welding wire storage 1 of this Embodiment is conveyed several times after being manufactured by the manufacturer until it is actually used by the user. Here, in the welding wire storage 1 immediately after being manufactured by the manufacturer, the welding wire 20 constituting the wire coil 40 is stored in an orderly manner. However, with the welding wire storage 1 being transported after manufacture, the welding wire storage 1 is in a state where it can receive various impacts. And when such an impact force is added to the welding wire storage thing 1, the arrangement | sequence of the welding wire 20 which comprises the wire coil 40 may be disturbed. Then, when pulling out the welding wire 20 from the welding wire storage 1, there is a concern that the kink that the welding wire 20 bends or the tangling (entanglement) of the welding wire 20 occurs due to the disorder of the arrangement of the welding wire 20.

  Here, in the present embodiment, the inner wall portion 13 is arranged inside the outer cylinder portion 12 in the welding wire storage container 10 constituting the welding wire storage article 1. And this inner wall part 13 was made into the uneven | corrugated structure which made the frame 31 the convex part, and made the connection body 32 the recessed part. Thereby, the outer peripheral side (the side facing the inner wall portion 13: corresponding to the coiled laminated outer diameter portion) of the wire coil 40 stored in the welding wire storage container 10 is a plurality of frames 31 constituting the inner wall portion 13. Point contact with the upper surface portion 312 at a plurality of locations. Then, compared with the case where the outer peripheral side of the wire coil 40 is brought into surface contact with the inner surface (flat curved surface) of the outer cylinder portion 12 as in the prior art, the wire coil 40 is applied at the contact site when subjected to the same impact. Strength increases. As a result, it is possible to suppress the disorder of the arrangement of the welding wires 20 constituting the wire coil 40 due to an impact received from the outside.

  As a result, when the welding wire 20 is supplied from the welding wire storage 1 to the welding apparatus, it is possible to easily avoid a situation in which the welding wire 20 is kinked or entangled.

  Here, in the present embodiment, the connection width D of the connection body 32 is made smaller than the bottom surface width A of the frame body 31 in the inner wall portion 13 (bottom surface width A> connection width D). That is, the outer peripheral side of the wire coil 40 accommodated in the welding wire storage container 10 is configured to be difficult to come into contact with the plurality of connection bodies 32 constituting the inner wall portion 13. Thereby, it can suppress that the welding wire 20 which comprises the outer peripheral surface of the wire coil 40 deform | transforms (bends) following the shape (unevenness | corrugation) of the inner peripheral surface of the inner wall part 13. FIG.

  In the present embodiment, in the frame 31 constituting the inner wall portion 13, the bottom surface width A of the bottom surface portion 311 is made larger than the top surface width B of the top surface portion 312 (bottom surface width A> top surface width B), and The upper surface width B of the upper surface portion 312 was made larger than the slope width C of the slope portion 313 (upper surface width B> slope width C). Thereby, it is possible to stably receive the force applied to the frame body 31 with the contact with the wire coil 40.

  Further, in the present embodiment, the frame body 31 and the connection body 32 constituting the inner wall portion 13 are connected to the bottom surface portion 311 side of the frame body 31. Thereby, the inner surface of the outer cylinder part 12 and the inner wall part 13 can be brought into surface contact, and the inner wall part 13 can be stably arranged in the welding wire storage container 10.

  Furthermore, in this Embodiment, the frame 31 which comprises the inner wall part 13 was made into the hollow structure. As a result, the frame 31 can be easily deformed with the contact with the wire coil 40, and the inner wall 13 can be reduced in weight. Here, in the present embodiment, it is possible to suppress excessive deformation of the frame 31 by providing the reinforcing portion 314 inside the hollow of the frame 31.

  Moreover, in this Embodiment, the frame 31 which comprises the inner wall part 13 was comprised with the thermosetting resin. Thereby, the intensity | strength of the frame 31 can be raised.

  Furthermore, in this Embodiment, the connection body 32 which comprises the inner wall part 13 was comprised with the thermoplastic resin. Thereby, when attaching the inner wall part 13 formed in flat form to the outer cylinder part 12, it becomes easy to make it curve in the connection body 32 and to make it cylindrical in the welding wire storage container 10. FIG.

  Hereinafter, the present invention will be described in more detail based on examples. However, the present invention is not limited to the following examples unless it exceeds the gist.

First, as an example, a welding wire storage container 10 shown in FIGS. 1 to 3 having an inner wall portion 13 shown in FIGS. 4 and 5 was prepared.
Moreover, what removed the inner wall part 13 from the welding wire storage container 10 shown in FIG. 1 thru | or FIG. 3 (thing which does not attach the inner wall part 13) was prepared as a comparative example.

  Here, the outer diameter (the diameter of the bottom plate 11) of the welding wire storage container 10 in each of the example and the comparative example was 662 mm, and the height (the length of the outer cylinder portion 12) was 500 mm.

  In the inner wall portion 13 of the welding wire storage container 10 in the example, the bottom surface width A was 30 mm, the top surface width B was 20 mm, the slope width C was 5 mm, and the connection width D was 5 mm. The height of the frame 31 (the length from the bottom surface 311 to the top surface 312) of the inner wall 13 was 15 mm.

  And with respect to the welding wire storage container 10 of an Example and the welding wire storage container 10 of a comparative example, on the conditions shown in the following Table 1, the welding wire of diameter 1.4mm which meets the specification of JISZ3312: 2009YGW11 20 was dropped, and the welding wire storage thing 1 which loaded the wire coil 40 in each welding wire storage container 10 was obtained.

  Each welding wire storage 1 obtained in this manner was subjected to linear marking along the radial direction on the upper surface of the wire coil 40 (hereinafter referred to as a laminated upper surface) with an oil pen. Moreover, the linear marking which followed the perpendicular direction was given to the inner surface (it calls a laminated inner surface below) of the wire coil 40 with respect to each welding wire storage thing 1 with an oil-based pen. Then, a holding plate (not shown) was disposed on the upper surface of the wire coil 40 for each welding wire storage item 1 and a vibration test for applying vibration for 3 minutes using a vibration device (not shown) was performed.

  FIG. 6 is a diagram (photograph) for explaining the state of the wire coil 40 after the vibration test of the example and the comparative example. Here, the left side of the figure shows the results of the example, and the right side of the figure shows the results of the comparative example. Further, the upper part in the figure shows the results of viewing the upper surface and inner surface of the wire coil 40 from obliquely above (VIa direction shown in FIG. 2), and the middle part in the figure shows the upper surface of the wire coil 40 above (VIb direction shown in FIG. 2). The lower part of the figure shows the result of viewing the inner surface of the laminated wire coil 40 from the side (VIc direction shown in FIG. 2). Here, in each photograph, the markings applied to the upper and inner surfaces of the wire coil 40 are highlighted. Note that, as described above, each marking was linear before performing the vibration test.

  As is apparent from FIG. 6, in the example, it is understood that the arrangement disorder of the wire coil 40 after the vibration test is suppressed as compared with the comparative example. This is due to the presence / absence of the inner wall portion 13 and is considered to be caused by the point contact between the outer peripheral side of the wire coil 40 and the inner wall portion 13 at a plurality of locations as described above.
