The present invention relates to a welding wire container and an in-container welding wire for receiving a coil of welding wire. In particular, the present invention relates to a welding wire receiving container applicable to a welding wire having a large rigidity of a solid wire.

As a container for accommodating a welding wire such as a solid wire or a flux cored wire, a generally cylindrical welding wire storage container is used (for example, Japanese Patent Publication No. 1984-8474). Publication and Japanese Patent Publication No. 1991-34424. 34 is a perspective view schematically showing a conventional welding wire container. FIG. 35 is a sectional view of the conventional welding wire receiving container shown in FIG. 34, and FIG. 36 is a perspective view showing only a retainer plate. As shown in Figs. 34 and 35, the conventional welding wire in a container is wound and housed in the container so that the welding wire 100a moves along a circular trajectory. The storage container holds a bottom plate 105 that forms a bottom portion inside the outer cylindrical portion 101. In the conventional welding wire storage container, the inner cylinder part 106 whose diameter is smaller than the outer cylinder part 101 may be arrange | positioned coaxially with the outer cylinder part 101. As shown in FIG.

Usually, the welding wire in a container is loosened in the state accommodated in the storage container. For this reason, when loosened, the welding wire 100a may become entangled or entangled with each other. For this reason, in the conventional in-vessel welding wire, the annular retainer plate 102 shown in FIG. 36 is mounted on the welding wire coil 100. The welding wire coil 100 is urged downward by the retainer plate 102 to prevent the loosened wire from protruding or intertwining with each other.

The retainer plate 102 in the conventional welding wire storage container has an outer diameter slightly smaller than the inner diameter of the outer cylindrical portion 101. In the case of the storage container provided with an inner cylinder part therein, the inner diameter of the retainer plate 102 is slightly larger than the outer diameter of the inner cylinder part 106. FIG. The welding wire 100a is released from a gap defined between the inner cylindrical portion 106 and the retainer plate 102. Since the retainer plate 102 can move vertically, even if the height of the welding wire coil 100 changes as the welding wire 100a is released, the retainer plate 102 is always on the welding wire coil 100. Is mounted on.

Conventionally, a retainer plate is also proposed in which a plurality of introverted elastic pieces are disposed on a band plate-shaped vertical wall portion in order to prevent the welding wire from being entangled when unwound (JP-A-1998-218493). Reference). This retainer plate is rounded in an annular shape. The retainer plate is mounted on the welding wire coil with the vertical wall portion in contact with the inner surface of the outer cylindrical portion and the inwardly elastic member in contact with the welding wire upper surface. The welding wire is pulled upward while contacting the edge portion of the inwardly elastic member of the retainer plate.

In the conventional welding wire container, it is necessary to prevent the welding wire from protruding from the gap defined between the retainer plate 102 and the outer cylindrical portion 101 in FIGS. 34 and 35. To this end, a plurality of strings 108 extending in the height direction of the outer cylindrical portion 101 are disposed between each retainer plate 102 and the welding wire coil 100 and the outer cylindrical portion 101. In addition, a ring 103 having a circular longitudinal section is disposed on the retainer plate 102. The ring 103 is disposed coaxially with the outer cylindrical portion 101 between the string 108 and the outer cylindrical portion 101. Ring 103 is held on retainer plate 102 via string 108 and moves along retainer plate 102. In addition, when the welding wire is continuously unwound, the winding trailing edge of the welding wire 100a, that is, the unwinding end of the welding wire 100a, in order to smoothly move from the current storage container to the next storage container. The unwound trailing edge is fixed by a plurality of clamps 107 arranged above the inner surface of the outer cylindrical portion 101. By this configuration, this loosening end (winding tip) is connected to the loosening tip of the welding wire in the container to be loosened next. As a result, the plurality of welding wires in the container can be released continuously (see Japanese Patent Publication No. 1989-15353).

However, in the conventional container for welding wire storage, as shown in FIG. 35, the lower end of the outer cylindrical part 101 is cocked, and the bottom plate 105 is fixed to the lower end of the outer cylindrical part 101. This caulking facilitates positioning of the bottom plate when the bottom plate 105 is inserted into the outer cylindrical portion 101, and assists a curling process for fixing the bottom plate 105 by attaching a guide. do. However, when the welding wire coil 100 is released, the retainer plate 102 is inevitably retained by a caulking portion having an inner diameter smaller than that of other portions of the outer cylindrical portion 101. Because of this, the welding wire coil 100 located below the caulking portion cannot be pressed by the retainer plate 102. As a result, the wire located between the caulking portion and the bottom plate 105 pops out, causing the welding wire to become entangled and scattered.

For this reason, the method of raising the bottom part of a storage container by laminating | stacking a plate etc. on the bottom plate 105 is examined. 37 is a cross-sectional view showing a welded wire container having a raised bottom portion. In the welding wire container shown in Fig. 37, the disk 109 is bonded to the upper surface of the bottom plate 105 with an adhesive or the like. The disk 109 has an outer diameter that can be inserted into the caulking portion and a thickness that is the same in dimension as the height of the caulking portion. By this structure, the bottom part of the storage container is raised and the upper surface of the welding wire in the lowest layer is on the caulking part. As a result, the welding wire can be pressed to the lowest layer by the retainer plate 102.

Moreover, the welding wire storage container provided with the retainer plate which a plurality of rectangular blade members are attached to the annular plate 121 and protrudes from the inside and the outside of the annular plate 121 is examined. The annular plate 121 has an inner diameter smaller than the outer diameter of the inner cylindrical portion and an outer diameter smaller than the minimum inner diameter of the outer cylindrical portion (see Japanese Patent Laid-Open No. 1990-147566). It is a top view which shows the retainer plate of a welding wire container. The retainer plate 120 is designed to press the welding wire coil downward by the annular plate 121 and to prevent the welding wire from protruding from the outer cylindrical portion side and the inner cylindrical portion side by the blade member 122. The retainer plate 120 has an outer diameter smaller than the inner diameter of the caulking portion so as to enter the caulking portion. As a result, the retainer plate 120 can press the welding wire to the lowest layer.

However, the conventional welding wire storage container described above has the following problems. As shown in FIG. 37, the conventional welding wire storage container having a raised bottom may press the welding wire coil 100 to the lowest layer by the retainer plate 102. However, the conventional welding wire storage container has a problem that a gap is formed between the disk 109 and the outer cylindrical portion 101, and the wire is caught in the gap to stop the supply of the wire. In this way, the residual amount of the welding wire coil is reduced, and the problem that the supply of the welding wire is stopped may occur near the bottom of the storage container. In such a case, when a plurality of welding wires in the container are used continuously, all the welding wires stored in the container cannot be taken out smoothly, and it is impossible to move from the current storage container to the next storage container. In addition, by increasing the thickness of the disk 109, it is possible to set the bottom portion of the storage container on the caulking portion to remove the gap between the disk 109 and the inner surface of the outer cylindrical portion 1. However, as the lift amount of the bottom portion increases, the amount of wire that can be stored in the container decreases. As a result, workability | operativity at the time of use falls, and manufacturing cost rises. Therefore, the conventional welding wire is not preferable.

In addition, in the welding wire storage container provided with the retainer plate 120 shown in FIG. 38, the portion between the retainer plate 120 and the outer cylindrical portion of the welding wire coil is held only at some positions by the blade member 122. . For this reason, there exists a possibility that the welding wire in an outer side cylindrical part may stick out. Moreover, the retainer plate 120 moves downward while the blade member 122 projecting inwardly contacts the outer surface of the inner cylindrical portion, and the blade member 122 projecting outwardly contacts the inner surface of the outer cylindrical portion. . For this reason, the retainer plate 120 tends to be inclined obliquely, and there is a problem in that the wires are easily entangled or entangled with each other.

 The present invention has been made in view of the problems with the conventional storage container, and an object of the present invention is to provide a welding wire storage container capable of smoothly unwinding the welding wire to the outermost layer of the welding wire without causing entanglement or entanglement.

In order to achieve the above object, according to the first aspect of the present invention, there is provided an outer cylindrical portion made of paper, a bottom plate held by the inside of the outer cylindrical portion at a caulking portion below the outer cylindrical portion, and forming a bottom portion, and a welding wire nose. A welding wire storage container for receiving a welding wire coil, which is mounted on a daily routine and includes a retainer jig that descends as the filler coil wire decreases, and an annular member mounted on the retainer jig and having an outer diameter smaller than the minimum inner diameter of the outer cylindrical portion. Is provided. The retainer jig is formed by winding a band-like member, and includes a tube portion having an adjustable diameter and a plurality of blade portions extending from the inner inner edge of the lower portion of the tube portion toward the center of the tube portion. When withdrawing the welding wire from the container, the annular member acts as a weight against the retainer jig.

In order to achieve the above object, according to the second aspect of the present invention, there is provided an outer cylindrical portion made of paper, a bottom plate held by the inside of the outer cylindrical portion at a caulking portion below the outer cylindrical portion, and forming a bottom portion, and a welding wire nose. There is provided a welding wire receptacle that is mounted on a daily basis and receives a welding wire coil including a retainer jig that descends as the filler coil wire decreases. The retainer jig includes two annular portions on its upper side and its lower side. The outer diameter of the annular portion on the lower surface side is smaller than the minimum inner diameter of the outer cylindrical portion. The outer diameter of the annular portion on the upper surface side is larger than the minimum inner diameter of the outer cylindrical portion and smaller than the maximum inner diameter of the outer cylindrical portion.                         

In order to achieve the above object, according to a third aspect of the present invention, there is provided a paper outer cylindrical portion, a bottom plate held by the inside of the outer cylindrical portion at a caulking portion below the outer cylindrical portion and forming a bottom portion, and a welding wire nose. There is provided a welding wire receptacle that is mounted on a daily basis and receives a welding wire coil including a retainer jig that descends as the filler coil wire decreases. The retainer jig includes an annular plate having an outer diameter smaller than the minimum inner diameter of the outer cylindrical portion. The plurality of blade portions are disposed on the annular plate and extend in the circumferential direction of the annular plate and protrude upwards.

In the present invention, the retainer jig moves while contacting the inner surface of the outer cylindrical portion. According to this structure, a welding wire can be prevented from protruding from the outer side cylindrical part side. As a result, even if the bottom is not raised as in the conventional welding wire container, the welding wire can be smoothly released downward to the lowest layer of the welding wire without being entangled or entangled.

In addition, in the first aspect of the present invention, the outer diameter of the annular member is smaller than the inner diameter of the caulking portion of the outer cylindrical portion. Therefore, even when the pipe cannot be moved downward from the caulking portion when the welding wire is released, the blade portion and the annular member can enter the portion below the caulking portion, and the welding wire coil is moved downward to a position lower than the caulking portion. Can be pressurized. As a result, it is possible to smoothly unwind the welding wire downward to the lowest layer of the welding wire without generating entanglement or entanglement.

Furthermore, in the second aspect of the present invention, the outer diameter of the annular portion on the lower surface side is smaller than the minimum inner diameter of the outer cylindrical portion. For this reason, even when the pipe portion cannot move downward from the cocked portion when the welding wire is released, the annular portion on the lower surface side may enter the caulking portion and press the welding wire coil downward to the position of the caulking portion or lower. Can be. As a result, even if the bottom is not raised as in the conventional welding wire storage container, it is possible to smoothly unwind the welding wire downward to the lowest layer of the welding wire without causing entanglement or entanglement.

These and other objects and advantages of the invention will be fully understood from the following detailed description taken in conjunction with the accompanying drawings.

(First embodiment of the present invention)

Hereinafter, the container for welding wire storage according to the first embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

(Basic Structure of Welding Wire Storage Container)

1A is a cross-sectional view showing a welding wire receiving container according to a first embodiment of the present invention, and FIG. 1B is a plan view thereof. In the welding wire storage container according to the present embodiment, the upper portion of the cylindrical outer cylindrical portion 1 is slightly caulked. The bottom plate 5 forming the bottom portion of the storage container is fitted into the lower portion closest to the caulking portion and held inside the outer cylindrical portion 1. This bottom plate 5 is fixed to the outer cylinder part 1 by the metal reinforcing band which wraps the caulking part of the outer cylinder part 1 and the bottom surface of the bottom plate 5 as mentioned later. In general, since the welding wire storage container accommodates 250 kg to 500 kg of welding wire, a safe and rigid structure is required during transportation and suspension transportation. For this reason, from the viewpoint of light weight and electrical insulation, the outer cylindrical portion 1 of the welding wire storage container according to the present embodiment is made of multilayer paper or the like as described later.

In the welding wire storage container according to the present embodiment, the inner cylindrical portion 6 having a smaller diameter than the outer cylindrical portion 1 is disposed coaxially with the outer cylindrical portion 1 in the outer cylindrical portion 1. It is. The lower end of the inner cylindrical portion 6 is fixed on the bottom plate 5. The inner cylindrical portion 6 acts as a guide when the welding wire 10a is pulled out. The bottom surface of the inner cylindrical part 6 is fixed to the bottom plate 5 with a screw or an adhesive agent. Alternatively, the inner cylindrical portion is arranged so that a guide having an outer diameter corresponding to the inner diameter of the inner cylindrical portion 6 is previously disposed on the bottom plate 5 and fits the bottom surface of the inner cylindrical portion 6 onto the guide. (6) can be detachably positioned.

(The number of lamination of the paper sheet of the outer cylinder part)

In this example, in order to improve the pressure capacity, for example, the outer cylindrical portion 1 is preferably formed of a laminated body having a thickness of 4 mm to 6 mm in which eight or more sheets of paper are laminated. The pressure capacity of the outer cylindrical portion is about 1500 kgf / m 2 in consideration of the case where three storage containers are stacked, transported and stored. In this regard, with respect to the standard scale, when the inner diameter of the storage container is 500 mm and the load welding wire is 300 kg, the number of laminated sheets of paper sheets is set to 10 or more. Similarly, when the inner diameter of the storage container is 600 phi and the load welding wire is 400 kg, the number of laminated sheets of paper sheets is set to 11 or more sheets. Similarly, in the case where the inner diameter of the storage container is 660 mm and the load welding wire is 500 kg, the number of laminated sheets of paper sheets is set to 12 or more. In addition, the basis weight of the paper sheet to be used is, for example, about 200 g / m 2 to 300 g / m 2.

In the welding wire storage container having the basic structure according to the present invention, the welding wire 10a has its central axis moved and displaced along the circular trajectory on the bottom plate 5 at the outer peripheral side of the inner cylindrical portion 6. It is wound as much as possible. As a result, the welding wire 10a is housed inside the outer cylindrical portion 1.

The welding wire receiving container according to the present embodiment is mounted on the wound welding wire coil 10 to prevent the welding wire from protruding, and the retainer jig 2 is mounted on the retainer jig 2 and the welding wire coil ( And an annular plate 3 that is an annular member that presses 10 downward.

(Retainer Jig)

2 is a perspective view showing the shapes of the retainer jig 2 and the annular plate 3. 3, 4A and 4B are enlarged perspective views showing the shape of the blade portion of the retainer jig 2. As shown in Figs. 2 and 3, the retainer jig 2 includes a pipe portion 2a and a plurality of blade portions 2b. The tube portion 2a is formed by winding the band-shaped member roundly and has an adjustable diameter. The plurality of blade portions 2b extend from the inner edge of the lower portion of the tube portion 2a toward the center of the storage container. When the welding wire 10a is pulled out of the container, the annular member 3 acts as a plummet to the retainer jig 2.

More specifically, the tube portion 2a of the retainer jig 2 is formed by, for example, winding a paper band roundly. Since the ends of the paper bands are each divided and not joined to each other as will be described later, the diameter (length) of the retainer jig 2 can be adjusted according to the inner diameter of the outer cylindrical portion 1. It is preferable that the tube portion 2a is wound round so that both ends of the paper band overlap each other.

The shape of the blade portion 2b in the retainer jig 2 is substantially triangular in plan view in which the width of the blade portion 2b narrows toward the tip of the blade portion 2b. In addition, the blade portion 2b is made of a flexible or elastic resin material such as polyethylene terephthalate (PET) resin.

The blade portion 2b is required to prevent the welding wire from protruding in contact with the welding wire and to move in the front-rear direction without disturbing the movement for drawing or accommodating the welding wire. At this time, the blade portion 2b is necessary in order not to generate scratches on the surface of the welding wire. In order to satisfy the above requirement, the blade portion 2b is preferably substantially triangular in shape.

In addition, the blade portion 2b is preferably made of a resin material having flexibility or elasticity, such as the PET resin, in order to exhibit the function. Moreover, since the PET resin is transparent, the state of the welding wire coil 10 housed downward can be visually observed even in the state where the retainer jig 2 is located. Therefore, the blade portion 2b is preferably made of a transparent resin material even when using a resin other than PET. According to the above configuration, even if no openings or the like are formed in the retainer jig, the remaining amount of the filler coil can be easily confirmed.

In the welding wire storage container according to the present invention, the length of the blade portion 2b is set such that the tip thereof does not come into contact with the inner cylindrical portion 6. That is, the diameter of the circle formed by the line which connects the front end of the blade part 2b becomes larger than the outer diameter of the inner cylinder part 6.

However, the present invention is not limited to the above configuration, and the blade portion 2b may be in contact with the inner cylindrical portion 6. When the blade portion 2b is in contact with the inner cylindrical portion 6, the wire can be drawn out more stably in the storage container. When the blade portion 2b is brought into contact with the inner cylindrical portion 6, the resistance of the retainer jig 2 with respect to the inner cylindrical portion 6 increases when the retainer jig 2 is lowered. For this reason, it is preferable that the length of the blade part 2b is set to such an extent that the retainer jig 2 can fall smoothly.

On the other hand, as in the welding wire receiving container according to the present embodiment, when the tip of the blade portion 2b does not contact the inner cylindrical portion 6, the retainer jig 2 can be smoothly lowered. However, the withdrawal of the wire may be slightly unstable. Therefore, it is preferable that the length of the blade portion 2b is appropriately selected according to the wire characteristics such as tension strength, tension variation, wire diameter and the like of the drawn wire. The mass of the retainer jig 2 is, for example, 300 g to 370 g, and the total mass of the mass of the retainer jig 2 and the mass of the annular plate 3 is, for example, about 800 g to 1500 g.

(Annular member)

The annular plate 3 is mounted on the blade part 2b of the retainer jig 2, pressurizes the welding wire coil 10 downward, and the said function of the blade part 2b (retainer jig 2) is performed. Assist in doing. The retaining pressure applied on the wire is further required as the tension of the wire increases. Since the holding force of the blade portion 2b alone is insufficient to hold the wire, it is necessary to provide the annular member 3. For this reason, the annular member 3 is an annular plate (ring) in the present embodiment, and is made of, for example, paper, plastic, metal or laminated wood. The inner diameter of the annular plate 3 is larger than the outer diameter of the inner cylindrical portion 6. The outer diameter of the annular plate 3 is smaller than the minimum inner diameter of the outer cylindrical portion 1, that is, the inner diameter of the caulking portion.

Specifically, for example, the outer diameter of the inner cylindrical portion 6 is 310 mm regardless of the inner diameter of the outer cylindrical portion 1. When the nominal inner diameter of the outer cylindrical part 1 is 500 mm, the minimum inner diameter of the outer cylindrical part 1 is 480 mm, the inner diameter of the annular plate 3 is 325 mm to 335 mm, and the annular plate 3 The outer diameter of is 460 mm to 470 mm. In addition, the thickness of the annular plate 3 is about 3 mm, for example. In the case where the nominal inner diameters of the outer cylindrical portion 1 are 600 mm and 660 mm, the outer diameter of the annular plate 3 may be set large according to the nominal inner diameter of the outer cylindrical portion 1.

It is also desirable to adjust the mass of the annular plate 3 to adjust the holding force which assists in performing the above functions of the blade portion 2b. For this reason, in this embodiment, in order to adjust the mass of the annular plate 3, the weights 4 respectively formed by the steel plate are arrange | positioned on the annular plate 3 at substantially equal intervals. The total mass of the annular plate 3 and the weight 4 may be appropriately selected depending on the type of welding wire to be housed or the winding method of the welding wire. For example, when the above configuration is applied to a solid wire having a diameter of 12 mm or 14 mm, it is preferable to adjust the total mass of the annular plate 3 and the weight 4 to 800 g to 1500 g.

(Operation of the welding wire storage container)

Next, the operation of the welding wire storage container constructed in accordance with the present embodiment as described above, that is, the method of accommodating the welding wire in the container and the method of releasing the welding wire in the container will be described in more detail. Referring to FIG. 1, first, when storing a welding wire in a container, the welding wire is laminated on the bottom plate 5 while moving the central axis along the circular track from the bottom upwards. The retainer jig 2 is mounted on the laminated welding wire coil 10. Furthermore, on the blade portion 2a of the retainer jig 2, an annular plate 3 with a weight 4 attached thereto is coaxially mounted with the welding wire coil 10 to provide the welding wire in the container.

When carrying and storing this welding wire in a container, the upper end of the outer cylindrical part 1 is covered with the cover (cover 50 in FIG. 24 mentioned later). At this time, a paper spacer (not shown) is disposed between the retainer jig 2 and the cover. The spacer used in the welding wire container according to the present embodiment is, for example, a small rectangular cylinder is inserted into a large cylindrical cylinder, and a small cylindrical cylinder is formed from a large cylindrical tube. It is configured to protrude. One or more string or band elastic members extend on the inside of the large-diameter rectangular tube portion. In the spacer, the lower end portion of the small rectangular cylinder portion extends into the large rectangular cylinder portion. Therefore, the height at which the small diameter rectangular tube portion protrudes from the large diameter rectangular tube portion can be changed depending on the distance between the cover and the retainer jig 2. For this reason, even if the winding of the wire clings due to vibration or the like during transportation, or the height of the welding wire coil becomes low, the welding wire coil can be pressed downward. As a result, the welding wire coil is prevented from loosening the welding wire coil due to the vibration during transportation, thereby preventing entanglement and entanglement of the welding wire when the welding wire is released.

On the other hand, when the welding wire 10a is loosened, the cover and the spacer are removed, and the wire end at the time of winding is drawn out from the gap formed between the inner cylindrical portion 6 and the annular plate 3. The welding wire is released from the upper layer of the welding wire coil 10 toward the lower layer with the wire end as the disengaging tip. At this time, the retainer jig 2 and the annular plate 3 move downward as the height of the welding wire coil 10 decreases.

In the welding wire storage container according to the present embodiment, the outer diameter of the annular plate 3 is smaller than the inner diameter of the caulking portion of the outer cylindrical portion 1, and the blade portion 2b is made of a flexible resin material such as PET. . Accordingly, even when the pipe portion 2a is held by the caulking portion and cannot move downward from the caulking portion, the welding wire coil 10 located below the caulking portion is pressed downward. This is because the blade portion 2b and the annular plate 3 enter the lower portion than the caulking portion. As a result, even if the bottom is not raised as in the conventional welding wire container, the welding wire can be smoothly released downward to the lowest layer of the welding wire without being entangled and entangled. As described above, the welding wire storage container according to the present embodiment is particularly effective in the case where the supply of the welding wire is not stopped during use, when the welding wires in the container are continuously used.

In addition, in the welding wire storage container according to the present embodiment, the pipe portion 2a of the retainer jig 2 moves while contacting the inner surface of the outer cylindrical portion 1. For this reason, since a clearance gap does not generate | occur | produce between the retainer jig 2 and the outer side cylindrical part 1, it can prevent that a wire protrudes from the outer side cylindrical part 1 side of a welding wire coil. Therefore, the string and the ring arrange | positioned at the conventional welding wire storage container shown in FIG. 35 become unnecessary. Moreover, in the retainer jig 2 of the welding wire storage container according to the present embodiment, since the pipe portion 2a made of paper or the like moves along the inner surface of the outer cylindrical portion 1, the outer cylindrical portion 1 It can also be applied to a storage container having no inner cylindrical portion 6 therein.

Moreover, the retainer jig 2 of the wire storage container according to the present embodiment has a higher effect of preventing entanglement and entanglement than the conventional retainer plate. This is because the retainer jig 2 is inclined obliquely because the tip of the blade portion 2b moves without contacting the outer surface of the inner cylindrical portion 6. In addition, in the welding wire storage container according to the present embodiment, since the blade portion 2b of the retainer jig 2 is made of a transparent resin material such as PET, the residual amount of the welding wire coil 10 is easily visually observed. You can check it. For this reason, it is not necessary to provide the annular plate 3 with an opening for checking the residual amount of the welding wire coil 10 as in the conventional retainer plate.

(Example of retainer jig)

Hereinafter, another example and the more specific example of the retainer jig 2 are demonstrated. In the retainer jig 2 according to the embodiment described with reference to FIGS. 1A, 1B, 2 and 3, the blade portion 2b, which is substantially triangular in plan view, is approximately perpendicular 90 to the tube portion 2a. Fitting to the pipe section 2a. As shown in FIG. 3, the angle θ formed between the blade portion 2b and the tube portion 2a may be appropriately selected in the range of 75 ° to 100 °. By facilitating entry of the blade portion 2b into the caulking portion, this range is selected to obtain the effect of preventing entanglement and entanglement of the welding wire in the caulking portion.

However, the present invention is not limited to the above configuration. For example, part of the blade portion can be folded inward. In addition, the thickness of the blade portion 2b is, for example, about 0.4 mm to 0.6 mm. 4A and 4B are enlarged views showing another shape of the blade portion of the retainer jig. In the retainer jig shown in FIG. 4A, the edge part of each blade part 2b by the side of the pipe part 2a is folded inward, and is inclined. Inclination angle (alpha), height (a), and width (b) in inclination part can be suitably set according to the shape of a caulking part. In this embodiment, for example, the inclination angle α is about 46 ° to 50 °, the height a is about 17 mm to 21 mm, and the width b is about 15 mm. Thus, the edge part of the blade part 2b by the side of the pipe part 2a is folded inward, and it inclines, and it can make it easy for the blade part 2b to enter a caulking part. As a result, the effect of preventing entanglement and entanglement of the welding wire in the caulking portion is improved.

Furthermore, as shown in Fig. 4B, the inclined portion may be formed at the end floating of the blade portion 2b on the tube portion 2a side, and the tip portion of the blade portion 2b may be folded inward. As a result, positioning of the annular plate 3 at the time of mounting the annular plate 3 on the blade portion is facilitated, and the inner edge of the annular plate 3 is held by the folded portion of the blade portion 2b. . By the above configuration, it is possible to prevent the annular plate 3 from moving laterally at the time of loosening.

(Length adjustment of the retainer jig)

Next, a specific example of the adjustment of the length (outer diameter) of the retainer jig 2 will be described. The paper portion of the retainer jig 2 (the paper forming the pipe portion 2a) is the same material as the material of the outer cylindrical portion, for example, when the basis weight is 200 g / m 2 to 300 g / m 2, the thickness of the paper is approximately. 4 mm to 6 mm] is required to move while in contact with the inner surface of the outer cylindrical portion 1. For this reason, the length (outer diameter) of the pipe part 2a needs to be adjusted according to the inner diameter of the outer cylindrical part 1. If the length (outer diameter) of the pipe part 2a is inappropriate, the contact force of the retainer jig 2 with the inner surface of the outer cylindrical part 1 will weaken, the effect of the retainer jig 2 will fall, and a wire will become tangled easily. Lose.

Means for adjusting the length (outer diameter) of the pipe portion 2a are shown by a partial perspective view of the pipe portion 2a of FIGS. 5 to 7. 5 to 7, the tube portion 2a of the retainer jig 2 has an annular gap 8, and the two annular plates 2d and 2e have an annular plate 2d disposed on the inner circumferential side and annular. The plates 2e are laminated so as to be disposed on the outer peripheral edge side. 5 to 7, the pipe portion 2a is divided at one place, and in the split portion 13, the pullout member 2c is formed at one end of the pipe portion 2a. On the left side of the drawing). Then, the pull-out member 2c is inserted into the gap 8 at the other end (right side of the drawing) of the pipe portion 2a, and the length of the pull-out member 2c to be inserted is adjusted to adjust the length of the pipe portion 2a. You can adjust (OD).

In Fig. 5, in order to engage the inserted pull-out member 2c, a substantially rectangular solid stopper 9a made of a lightweight elastic member such as styrofoam is provided at the other end of the pipe portion 2a. On the gap 8 (on the right side of the figure) (on the pull-out member 2c). The force exerted on the pull-out member 2c when drawing out the welding wire (when loosening) is only applied upwards. For this reason, if the stopper 9a is only on the pullout member 2c, the pullout member 2c can be locked.

In Fig. 6, in order to lock the inserted pull-out member 2c, the annular plates 2d and 2e are placed on the gap 8 (on the pull-out member 2c) of the pipe portion 2a at the left side of the figure. (9b) and so on.

In Fig. 7, a hollow rectangular sliding guide 9c is provided for locking the inserted pull-out member 2c. The sliding guide 9c vertically surrounds the outer periphery of the pipe portion 2a and fixes the pull-out member 2c in the gap 8.

(Example of annular member)

Hereinafter, other examples and more specific examples of the annular member will be described. 8 is a perspective view showing the shapes of a ring and a retainer jig that are annular members. In FIG. 8, the structure of the retainer jig 2 is the same as that of the said embodiment shown in FIG. 1A, FIG. 1B, and FIG.

In the welding wire container according to the embodiment shown in FIGS. 1A, 1B and 2, the paper annular plate 3 is mounted on the retainer jig 2. However, the present invention is not limited to this configuration. For example, as shown in Fig. 8, a metal ring 7 having a substantially rectangular vertical cross section may be mounted on the retainer jig 2 as an annular member. Like the annular plate 3, the ring 7 has an inner diameter larger than the outer diameter of the inner cylindrical portion 6 and an outer diameter smaller than the minimum inner diameter of the outer cylindrical portion 1.

More specifically, for example, when the outer diameter of the inner cylindrical portion 6 is 310 mm, and the minimum inner diameter of the outer cylindrical portion 1 is 480 mm, the inner diameter of the ring 7 is 350 mm to 360 mm, The outer diameter of the ring 7 is 460 mm to 470 mm. As mentioned above, in the welding wire container according to this modification, since the ring 7 is made of metal, no additional is required. The mass of the ring 7 may be appropriately set according to the type of the received welding wire or the winding method of the welding wire. For example, when this configuration is applied to a solid wire having a diameter of 1.2 mm or 1.4 mm, the mass of the ring 7 is preferably set to about 800 g to 900 g. In addition, it is preferable to set the total mass of the retainer jig 2 and the ring 7 to about 1100 g to 1500 g.

The ring 7 may be formed by joining a plurality of ring members to each other by welding. However, the present invention is not limited to this configuration. The ring 7 may be integrally molded.

In the welding wire receiving container according to the embodiment shown in FIGS. 1A, 1B and 2, the ring 7 is used as an annular member instead of the annular plate 3 on the blade portion 2b of the retainer jig 2. In the case of arranging), the welding wire is received in the container to provide the welding wire in the container. In addition, the welding wire can be smoothly unrolled downward to the lowest layer of the welding wire without entanglement and entanglement.

(2nd Embodiment of this invention)

Hereinafter, the container for welding wire storage according to the second embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

9 is a sectional view showing a welding wire receiving container according to the present embodiment. The basic structure of the welding wire receiving container and the receiving state of the welding wire 10a according to the present embodiment are the same as those shown in FIGS. 1A and 1B.

(Retainer Jig)

In the present embodiment, the welding wire receiving container shown in FIG. 9 includes a retainer jig 2 mounted on the wound welding wire coil 10. FIG. 10A is a perspective view showing the shape of the retainer jig 2, and FIG. 10B is a side view thereof.

As shown in Figs. 10A and 10B, the retainer jig 2 includes two annular portions 2f and 2g, respectively, on the upper surface side and the lower surface side. The outer diameter of the annular portion 2g on the lower surface side is smaller than the minimum inner diameter of the outer cylindrical portion 1. The outer diameter of the annular portion 2f on the upper surface side is larger than the minimum inner diameter of the outer cylindrical portion 1 and smaller than the maximum inner diameter of the outer cylindrical portion 1. That is, the retainer jig 2 is an annular plate whose diameter of the annular part 2f of the upper surface side is larger than the diameter of the annular part 2g of the lower surface side.

The retainer jig 2 is formed of corrugated cardboard or plywood, for example. The retainer jig 2 is formed by, for example, joining or integrally molding two annular portions 2f and 2g on the upper surface side and the lower surface side.

In the case where the inner cylindrical portion 6 is used for the welding wire receiving container, the retainer jig 2 has an inner diameter r2 larger than the outer diameter of the inner cylindrical portion 6 and the minimum inner diameter of the outer cylindrical portion 1, ie It has a minimum outer diameter r3 smaller than the inner diameter of a caulking part. The retainer jig 2 has a maximum outer diameter r1 that is larger than the inner diameter of the caulking portion of the outer cylindrical portion 1 and smaller than the maximum inner diameter of the outer cylindrical portion 1. Specifically, if the outer diameter of the inner cylindrical portion 6 is set to 310 mm irrespective of the maximum inner diameter of the outer cylindrical portion 1, for example, the maximum inner diameter of the outer cylindrical portion 1 is 500 mm, the outer cylinder It is preferable that the minimum inner diameter of the part 1 is set to 480 mm, and the inner diameter r2 of the retainer jig 2 is set to 322 mm-328 mm. Moreover, it is preferable that the minimum outer diameter r3 is set to 470 mm-475 mm, and the maximum outer diameter r1 is set to 489 mm-491 mm. Moreover, the thickness of the retainer jig 2 can be appropriately set in accordance with the height of the caulking portion of the outer cylindrical portion 1. The thickness of the retainer jig 2 is set to 17 mm-20 mm, for example. In addition, the mass of the retainer jig 2 is 400 g to 800 g when the welding wire is formed of a positive cored wire.

The retainer jig 2 is arrange | positioned so that the annular part 2g of the lower surface side with a small outer diameter may form the lower surface of the retainer jig 2. Moreover, it is preferable that resin films, such as a laminate film, adhere to the lower surface of the retainer jig 2. This configuration makes it possible to smoothly rewind the welding wire, and also makes it possible to transfer moisture adsorbed by the corrugated cardboard or the like to the welding wire. As a result, rust can be prevented from occurring in the welding wire. In addition, since slippage of the wire in the contact surface between the welding wire coil 10 and the retainer jig 2 becomes good, entanglement of the wire can be prevented.

(string)

In addition, a plurality of strings 12 may be attached on the inner surface of the outer cylindrical portion 1 of the welding wire storage container according to the present embodiment. The plurality of strings 12 extend in the longitudinal direction of the outer cylindrical portion 1, that is, in the height direction of the welding wire coil 10. The plurality of strings 12 prevents a gap between the retainer jig 2 and the outer cylindrical portion 1 and prevents the welding wire from protruding from the outer circumferential side of the welding wire coil 10 during loosening. Is provided. In this embodiment, the string 12 is arrange | positioned between the welding wire coil 10, the retainer jig 2, and the outer side cylindrical part 1, and extends in the height direction of the outer side cylindrical part 1. As shown in FIG. In addition, instead of the string 12, a plurality of sponge plates are arranged at substantially equal intervals on the outer circumferential edge of the retainer jig 2. Similarly, this configuration can prevent the wire from sticking out.

Further, in the case of attaching the plurality of strings 12 on the inner surface of the outer cylindrical portion 1 as described above, the ring 11 having a circular vertical cross section is formed on the retainer jig 2 by the outer cylindrical portion ( 1) is arranged coaxially. The ring 11 is disposed coaxially with the outer cylindrical portion 1 between the string 12 and the outer cylindrical portion 1. The ring 11 is held annularly on the upper surface of the retainer jig 2 and moves along the retainer jig 2.

Next, an operation of the welding wire storage container configured as described above, that is, a method of accommodating the welding wire in the container and a method of unwinding the welding wire in the container will be described with reference to FIG. 9. First, when accommodating the welding wire 10a in a container, the welding wire 10a is laminated | stacked on the bottom board 5, moving the central axis along a circular track | orbit from the bottom upwards. The retainer jig 2 is mounted coaxially with the inner cylindrical portion 6 on the laminated welding wire coil 10. In addition, a ring 11 is arranged between the string 12 and the outer cylindrical portion 1 on the retainer jig 2, thereby providing an in-vessel welding wire.

When carrying and storing the welding wire in the container wound and received by the above method, the upper end of the outer cylindrical portion 1 is covered with a cover (not shown). At that time, a paper spacer (not shown) is disposed between the retainer jig 2 and the cover. The welding wire coil 10 is pressed downward by the retainer jig 2, the ring 11, and the spacer. At this time, the spacer to be used is the same as the spacer (not shown) to be used in FIG. 1.

On the other hand, when the welding wire 10a is loosened, after the cover and the spacer are removed, the wire end at the time of winding is drawn out from the gap formed between the inner cylindrical portion 6 and the retainer jig 2. The welding wire is released from the upper layer of the welding wire coil 10 toward the lower layer with the wire end as the disengaging tip. At this time, the retainer jig 2 and the ring 11 move downward as the height of the welding wire coil 10 becomes low.

In the welding wire storage container according to the present embodiment, the outer diameter of the lower surface side portion of the retainer jig 2 is smaller than the inner diameter (minimum inner diameter) of the caulking portion of the outer cylindrical portion 1. Thus, the annular portion having a small outer diameter enters the caulking portion, and the caulking portion and the welding wire coil 10 located below are also pressed downwards.

As a result, even if the bottom is not raised as in the conventional welding wire container, the welding wire can be smoothly released downward to the lowest layer of the welding wire without being entangled and entangled. This is shown in the sectional view of Fig. 11 showing a state where the retainer jig 2 is lowered to the lower layer portion of the welding wire. As a result, the welding wire storage container according to the present embodiment is effective in the case of continuously using a plurality of welding wires in the container because the supply of the welding wire does not stop during use.

In addition, the effect as shown in FIG. 11 also applies to FIG. 1 described above.

In addition, in the welding wire storage container according to the present embodiment, the outer cylinder portion of the welding wire coil is formed because the gap 12 is arranged so that no gap is formed between the retainer jig 2 and the outer cylindrical portion 1. A wire can be prevented from protruding from the (1) side.

Moreover, in the welding wire storage container according to the present embodiment, most of the upper surface of the welding wire coil is covered with the retainer jig 2. As a result, moisture hardly enters the inside of the welding wire coil 10, and the antirust effect of the welding wire is excellent.

In addition, the retainer jig 2 of the welding wire container according to the present embodiment can be applied to a welding wire container that does not have the inner cylindrical part 6 inside the outer cylindrical part 1. It is sectional drawing which shows the welding wire storage container which does not have an inner cylinder part. As shown in FIG. 12, when the inner cylinder part 6 is not arrange | positioned inside the outer cylinder part 1, the welding wire 10a is made through the extraction hole 2h formed in the retainer jig 2. Passed.

Next, a modification of the retainer jig 2 will be described. 13-16 is a perspective view which shows each shape of the retainer jig 2 in the welding wire storage container which concerns on this modification. In the retainer jig 2 shown in FIG. 10, a retainer jig formed by stacking a plurality of annular plates made of cardboard or plywood is used. The present invention is not limited to this configuration. For example, as shown in Figs. 13 to 16, a retainer jig 2 integrally molded with a resin can be used. Examples of the resin include a polypropylene (polypropylene) resin, an acrylonitrile butadiene styrene (ABS) resin, a PET resin, a styrene (ST) resin and a polyethylene (PE) resin.

The retainer jig 2 shown in Figs. 13 to 16 has the retainer jig shown in Fig. 10 in that each retainer jig 2 has two annular portions 2f and 2g on the upper surface side and the lower surface side. Same as 2). However, in the retainer jig 2 shown in FIG. 13, the outer diameters of the two annular portions 2f and 2g on the upper surface side and the lower surface side are not stepped like the retainer jig 2 shown in FIG. It is slowly changing into vertical walls.

The retainer jig 2 shown in FIG. 14 has the same shape as that of FIG. 13, but the annular recess portion 13 is arranged on the upper surface of the flange of the annular portion 2f on the upper surface side in the circumferential direction. Formed. The recess portion 13 is a mounting surface of the weight having a shape corresponding to that shape.

The retainer jig 2 shown in FIG. 15 has the same shape as that of FIG. 10 except for arranging an annular plate weight (retainer jig) 14 on the lower face of the annular portion on the lower face side to increase the mass.

The retainer jig 2 shown in FIG. 11 is comprised by adding the recess part 13 of FIG. 14 to the retainer jig 2 of FIG.

Like the retainer jig 2 shown in FIG. 10, the retainer jig 2 shown in FIG. 16 has an inner diameter r2 greater than the outer diameter of the inner cylindrical portion 6. Further, the retainer jig 2 has a maximum outer diameter r1 smaller than the maximum inner diameter of the outer cylindrical portion 1 and a minimum outer diameter r3 smaller than the minimum inner diameter of the outer cylindrical portion 1.

Specifically, when the outer diameter of the inner cylindrical portion 6 is set to 310 mm irrespective of the maximum inner diameter of the outer cylindrical portion 1, for example, when the maximum inner diameter of the outer cylindrical portion 1 is 500 mm. It is preferable that the minimum inner diameter of the outer cylindrical part 1 is set to 480 mm, and the inner diameter r2 of the annular part 2f is set to 322 mm-328 mm. Moreover, it is preferable that the minimum outer diameter r3 is set to 470 mm-475 mm, and the maximum outer diameter r1 is set to 489 mm-491 mm. In addition, the thickness of the retainer jig 2 can be suitably set according to the height of the caulking part of the outer cylindrical part 1. The thickness of the retainer jig t is set to 17 mm to 20 mm, for example.

Moreover, the mass of the retainer jig 2 is for example 400 g to 800 g. For example, when the above configuration is applied to a solid wire having a diameter of 1.2 mm or 1.4 mm, it is further attached to the retainer jig 2 so that the total mass of the retainer jig 2 and the weight is set to about 1100 g to 1500 g. It is preferable. In this way, when the retainer jig 2 is made of resin, the shape of the retainer jig 2 is stabilized, and the surface smoothness of the retainer jig 2 is excellent. As a result, the welding wire can be released stably and the welding wire receiving container can be manufactured at low cost.

The structure of the welding wire storage container which concerns on this modification is the same as that of the embodiment of FIG. 1 except using the retainer jig 2 formed by injection molding resin. Thus, the welding wire is housed in the container to provide the welding wire in the container, and the welding wire can also be smoothly unrolled downward to the lowest layer of the welding wire without being entangled and entangled in the same manner as in the embodiment of FIG. 1. In such a configuration, a plurality of blade portions may be arranged on the flange upper surface of the annular portion 2f on the upper surface side of the retainer jig 2. The plurality of blade portions function to prevent the welding wire from protruding from the gap formed between the outer cylindrical portion and the retainer jig. This blade portion has an L-shaped shape which protrudes upward from the annular portion 2f and extends in the circumferential direction of the annular portion 2f as described below with reference to FIGS. 17 and 18.

(Third embodiment of the present invention)

Hereinafter, the container for welding wire storage according to the third embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

17 and 18 are perspective views showing the retainer jig according to the third embodiment of the present invention. The basic structure of the welding wire receiving container according to the present embodiment and the receiving state of the welding wire 10a are the same as those shown in FIGS. 1A, 1B and 9, and thus are omitted from the drawings.

(Retainer Jig)

17 and 18, the retainer jig 2 is formed of an annular plate 20 having an outer diameter slightly smaller than the minimum inner diameter of the outer cylindrical portion. In the case of using the inner cylindrical portion, the inner diameter of the retainer jig is set slightly larger than the outer diameter of the inner cylindrical portion. The welding wire is released from the gap formed between the inner cylindrical portion and the retainer jig 2.

The retainer jig presses the welding wire coil downwards to prevent the loosened wires from popping out or intertwining with each other. This has the same effect as the embodiment shown in Figs. 1A, 1B and 9.

In order to achieve the above effect, in this embodiment, a plurality of L-shaped blade portions 21 (four are shown in the drawing) are disposed on the annular plate 20. The plurality of L-shaped blade portions 21 protrude upward and extend in the circumferential direction of the annular plate 20. The blade portion 21 functions to prevent the wire from protruding from the gap formed between the outer cylindrical portion and the retainer jig. That is, the blade portion 21 has the same function as that of the ring 11 shown in FIG. 9 as described above.

Reference numeral 22 denotes a plurality of openings (four openings symmetrically shown in the drawing) arranged at predetermined intervals to confirm the remaining amount of the filler coil. It is preferable to be made of a flexible material such as a sponge to prevent the welding wire from being damaged. The difference between FIGS. 17 and 18 is that in FIG. 18 a means for adjusting the mass of the retainer jig is mounted on the portion of the annular plate 20 in which the blade portion 21 is present.

(Continuous loosening of multiple welding wire coils)

Hereinafter, a preferable example in which the welding wire is smoothly released while the plurality of welding wire coils are continuously released will be described. This example is common to each embodiment of the present invention, and is based on the configuration of the welding wire receiving container according to each of the above embodiments of the present invention.

In the case where the plurality of welding wire coils are to be continuously unwound, it is necessary to join the loose end of the weld wire coil to the loose end of the weld wire coil housed in another container to be subsequently loosened.

In order to join these welding wires together, as shown in FIG. 19 which shows the perspective view of a welding wire storage container, the release end (winding front end) 10b of the welding wire coil 10 is made into the inner surface of the outer cylindrical part 1. There is a need to provide a fastener 30 that secures the top of the. The loosening end 10b of the welding wire coil fixed by the fastener 30 is joined to the winding end (not shown) of the welding wire coil accommodated in the container in which the next welding wire is loosened. As a result, the plurality of welding wire coils can be released continuously. The fasteners 30 are located at one or a plurality of positions of the upper portion of the inner surface of the outer cylindrical portion 1 as necessary.

(Wire winding end fastener)

Specific examples of the fastener will be described with reference to FIGS. 20 to 23. 20 shows an example having a surface fastener as the fastener 30. As shown in FIG. 20, the flat hook side member 32 which comprises a surface fastener is adhere | attached on the inner surface 1a of the outer cylindrical part 1 by the adhesive (adhesive) 35, such as a rubber material. The drop-down tip (winding tip) 10b of the welding wire is each of the hook side members 32 and the respective flat loop side members engaged with the corresponding hook side members 32. member). By this configuration, the drop-down tip is hung on the inner surface side of the outer cylindrical portion 1. The loop side member and the hook side member may be interchanged with each other.

The hook side member 32 of the surface fastener is 20 mm-50 mm in width, and 50 mm-200 mm in length, for example. In FIG. 19, the hook-side member 32 is adhered to the inner surface of the outer circumferential cylindrical portion 1 at three or more positions along the inner circumferential direction of the outer cylindrical portion 1. The loop side member 31 is 20 mm-50 mm in width, and is 20 mm-200 mm in length, for example. The loop side member 31 is fixed to the corresponding hook side member 32. The hook side member 32 may be disposed over the entire circumference of the inner circumferential direction of the outer cylindrical portion 1. In the example of FIG. 19, the surface fastener 30 is disposed on the inner surface of the storage container in three positions while keeping its longitudinal direction horizontal. By this configuration, the drop-down tip of the welding wire is fixed at three positions.

21 and 22 are perspective views illustrating the surface fastener in more detail. As shown in these figures, the loop-shaped protrusion 33 is disposed on the loop side member 31. On the other hand, a hook-type protrusion 34 engaged with the loop-shaped protrusion 33 of the loop-side member 31 is disposed on the hook-side member 32. The loop side member 31 having such a looped protrusion 33 is placed on the hook side member 32 having the hooked protrusion 34. As a result, the loop-like protrusion 33 of the loop-side member 31 and the hook-like protrusion 34 of the hook-side member 32 are entangled with each other to fix the winding tip 10b of the wire between both sides.

Since the surface fastener 30 is made of a flexible material, the surface fastener may be attached along the inner surface of the welding wire receiving container. Therefore, even if the surface fastener is attached to the inner surface of the storage container with double-sided tape, the surface fastener does not fall. The protrusions of the hook side member 32 and the loop side member 31 of the cotton fastener are made of a single material or a composite material, such as nylon, polypropylene or polyester, for example.

In the case where the plurality of welding wire coils are continuously released, as shown in FIG. 19, the drop-down tip 10b of the welding wire is pulled upward from the welding wire receiving container and the surface fastener is placed on the upper surface of the inner surface of the welding wire receiving container. It is fixed by 30. That is, when the welding wire falls into the storage container in the form of a loop, the drop-down tip 10b is pulled upward from the storage container, and the welding wire coil is stored inside the storage container. After the drop is completed, the drop-down tip 10b is bent toward the inner cylindrical portion 6 side, and the retainer jig 2 is placed on the drop-down tip 10b. Then, the drop-down tip 10b passes through the inner edge of the retainer jig 2 and is fixed by the surface fastener 30 to the upper portion of the inner surface of the storage container.

Therefore, in the retainer apparatus of the welding wire, the drop-down tip 10b of the welding wire is pulled upward along the inner surface of the storage container. More specifically, the drop-down tip 10b of the welding wire passes through a gap formed between the upper surface of the welding wire coil and the lower surface of the retainer jig 2, such that the retainer jig 2 and the inner cylindrical portion 6 are formed. It is pulled upward through the gap between. The tip of the drop-down tip 10b is fixed to the inner surface of the storage container by the surface fastener 30. The welding wire coil 10 is housed so as to be stacked in a loop between the portion of the drop-down tip 10b along the inner surface of the container and the inner cylindrical portion 6. For this reason, the welding wire coil 10 in a storage container is drawn out sequentially from the upper side inside the storage container which is a drop-down end side, and is supplied to a torch. During this process, the drawn welding wire 10 is blocked by the drop-down tip 10b to prevent the supply of the welding wire, or the welding wire 10a and the drop-down tip 10b are not entangled with each other.

Next, the operation of the welding wire in the storage container constructed as described above will be described in association with the welding apparatus. The welding wire in the containment vessel is withdrawn sequentially from its drop-down end, which is continuously supplied to the welding apparatus and applied to the welding. First, two storage containers, each containing a welding wire, are arranged near the welding device. In each container, the drop-down tip 10b is fixed by the surface fastener 30 on the inner surface of the container. Thus, for example, before the start of use of the first storage container to be used first or during the use of the first storage container, the drop-down tip 10b is welded to the drop-down end of the welding wire in the second storage container to be used second. As a result, the drop-down tip 10b of the first storage container is joined to the drop-down end of the second storage container. When the tip and the end of the welding wire are joined to each other, the fastening state of the face fastener is released once. However, the tip and the end may be joined to each other without releasing the fixed state. After bonding, the drop down tip 10b may or may not be secured by the face fastener 30 again.

The welding wire in the receiving container is withdrawn from the drop-down end side and then supplied to the welding torch. The residual amount of the welding wire in the first container is reduced, and the current container is transferred to the second container. In this case, the drop-down tip 10b fixed by the surface fastener 30 on the inner surface of the storage container is released from the fixed state. The drop-down tip 10b is, of course, separated from the surface fastener 30. This is because the tension of the wire fed toward the torch is greater than the clamping force of the drop-down tip 10b due to the face fastener 30.

At this time, the drop-down end of the wire in the second storage container to be used after being joined to the drop-down tip 10b is continuously drawn out. Next, the welding wire in the second storage container is supplied toward the welding torch. Even after the drop-down tip 10b of the wire is separated from the face fastener 30, the loop side member 31 of the face fastener 30 is partially engaged with the hook side member 32 and does not fall.

On the other hand, after the drop-down tip 10b of the first storage container is joined to the drop-down end of the second storage container, the drop-down tip 10b may not be fixed by the surface fastener 30. In this case, after the drop-down front end 10b of the first storage container is taken out, the drop-down end of the second storage container is drawn out sequentially and fed. Thereafter, the wire in the second storage container is taken out.

Next, the first container containing no welding wire and the new third container containing the welding wire are replaced. Then, the welding wire in the second storage container is drawn out, or the drawing of the welding wire is stopped. At this time, the drop-down end of the welding wire in the third container is joined to the drop-down tip of the welding wire of the second container in the manner described above. In this way, the previous container drop-down tip is connected to the next container drop-down end. As a result, the welding wires in the plurality of storage containers are continuously fed to the welding torch to perform welding.

According to this embodiment, the drop-down tip 10b of the welding wire is fixed on the inner surface of the storage container by the surface fastener 30, and the drop-down tip 10b is connected to the drop-down end in the storage container to be used next. Is bonded in advance. As a result, the wires in the plurality of storage containers can be continuously and stably supplied without damage or deformation. In addition, the surface fastener 30 is used as a fastener (fixing member) of the drop-down tip 10b. As a result, it is less protruding on the inner surface of the storage container as compared with the conventional fixing jig such as the clamp member. Therefore, the welding wire can be smoothly laminated without being disturbed by the surface fastener 30 when the wire is dropped. In addition, the surface fastener 30 can be used repeatedly and is cheaper than the conventionally used integrally fastening members and clamp members, so that the running cost is also low.

Moreover, the drop-down tip 10b is reliably determined by the relationship between the fixing force of the drop-down tip 10b of the welding wire in the surface fastener and the peeling force between the hook-side member 32 and the loop-side member 31. Can be fixed When the welding wire is pulled with a force greater than the fixing force, the joining of the surface fasteners is easily released, and no elastic deformation such as damage or bending occurs in the wire.

When fixing the hook side member 32 and the loop side member 31 of the surface fastener 30 to the inner surface of the storage container, it is preferable to use a rubber adhesive or a resin adhesive, for example. However, the present invention is not limited to this configuration, and other adhesive means may be applied as long as they have the same adhesive force.

Furthermore, the inner cylindrical portion 6 is omitted, and when the welding wire is formed into loops each having a diameter smaller than the cross section of the container, the welding wire can be laminated so that the drop-down edge revolves, for example, in the container, while rotating. Can be.

The configuration of the surface fastener is not limited to the above example, and the following configuration is applicable to the present invention. That is, the hook side member 32 is adhered to the inner surface of the storage container over the entire circumference. Along the inner circumferential edge of the storage container on the hook side member 32, the loop side member 31 in a vertically arranged state is attached to a plurality of positions evenly. In this way, the drop-down tip 10b of the welding wire is fixed with the face fastener 30.

In addition, the arrangement direction of the surface fastener 30 is not limited to the said example. For example, the surface fastener 30 in a horizontal arrangement may be disposed on the inner circumference of the storage container along the inclined state of the wire. In addition, the surface fastener 30 in the arrangement state and the surface fastener vertically disposed at another inner peripheral position in the storage container may be appropriately combined with each other. In the present invention, any one of the above arrangements of the face fasteners is applicable, and the same effects as in the above embodiments can be achieved. The same applies to the replacement of the roof side members and the hook side members.

In addition, the protrusion structure of the surface fastener 30 is not limited to the example of FIG. 22, The protrusion of the loop side member 31 and the protrusion of the hook side member 32 are the loop type protrusion 33 and the hook type protrusion ( 34 may be modified to be alternately arranged. According to the arrangement, the projections of the loop-side member 31 and the projections of the hook-side member 32 tend to be entangled with each other, thereby improving the bonding strength. In this case, it is preferable that the loop-shaped protrusions 33 and the hook-like protrusions 34 on both sides are disposed to face each other.

Moreover, both the projections of the loop side member 31 and the projections of the hook side member 32 may be deformed to hook type projections. For example, both the protrusion of the loop side member 31 and the protrusion of the hook side member 32 may be deformed into a mushroom type hook protrusion whose tip is radially widened. Even with such a surface fastener, it is possible to reliably fix the drop-down tip of the wire and to prevent the wire from being damaged or deformed.

This type of surface fastener can be replaced with the clamped fastener 30 shown in the perspective view of FIG. The clamp fastener 30 includes a flat substrate 38, an upper member 36 having a rectangular cross section provided to protrude in the horizontal direction on the substrate 38, and a lower member 37 having a substantially triangular cross section. do. A gap narrower than these diameters (for example, 1.0 mm to 1.6 mm) is formed between these upper members and the lower members. The drop-down tip 10b of the wire is fixed to the gap. Such clamped fasteners 30 may be formed by injection molding, for example.

The clamped fastener 30 has, for example, a double-sided tape 35 on the back side of the substrate 38. The clamp-type fastener 30 is adhered to the upper portion of the inner surface of the storage container by the double-sided tape 35 or in a state where a sponge is interposed between the double-sided tape 35 and the substrate 38. However, in this fastener, since the adhesive force of the double-sided tape 35 is weak and the adhesive surface of the substrate in the fastener is flat, many problems arise that the substrate cannot be sufficiently adhered to the inner surface of the storage container which is a curved surface. . Therefore, a surface fastener type fastener is more preferable.

Hereinafter, the preferred embodiment which solves the other common problem required as a welding wire accommodating container besides the smooth loosening of a welding wire is demonstrated. The preferred embodiment is implemented by the construction of the welding wire receiving container having the above embodiment of the present invention.

(Antirust coating on welding wire storage container)

In the paper welding wire container, since the moisture and moisture easily enter the container from the outside, the welding wire may be oxidized or rust at the time of storage. Therefore, in order to prevent oxidation and rust of the storage container, an anti-rust layer such as a resin layer on an inner surface and an outer surface of the outer cylinder portion, an inner surface of the bottom plate, an outer surface of the inner cylinder portion, or a portion which easily enters moisture and moisture such as a cover. It is necessary to coat a rust resistant layer. Hereinafter, an example of the antirust coating will be described with reference to FIGS. 24 to 27.

24 is a cross-sectional view showing a welded welding container made of paper. FIG. 25 is a cross-sectional view illustrating a main part of FIG. 24. The basic structure of the welding wire container shown in Fig. 24 is the same as that of Figs. 1A, 1B and 9 described above. Fig. 24 shows a state in which a rust-proof layer 43 such as a resin layer is coated on the inner and outer surfaces of the outer cylindrical portion, the inner surface of the bottom plate, and the outer surface of the inner cylindrical portion.

More specifically, reference numeral 41 denotes a waterproof layer or a water repellent layer such as an acrylic resin having a water repellent action coated on the outer surface of the outer cylindrical portion 1. Reference numeral 40 is coated on the inner surface of the outer cylindrical portion 1, and indicates a mixed layer of the acrylic / wax resin layer and the acrylic resin layer difficult to pass moisture. Reference numeral 42 designates a polyethylene film or a rust preventive containing film coated on the inner surface (upper surface) of the bottom plate.

That is, the outer surface of the outer cylindrical portion 1 is coated with a waterproof layer, and as a result, since the outer surface of the storage container does not pass moisture, it is possible to prevent the mechanical properties of the storage container from deteriorating. In addition, moisture permeation can be suppressed from excessively drying the paper of the storage container, whereby the mechanical properties of the storage container can be properly maintained. Moreover, the inner surface of the outer cylindrical portion 1 and the inner surface of the bottom plate 5 are coated with a moisture proof (moisture impermeability or low moisture permeability) resin. As a result, moisture and moisture can be prevented from entering the inside of the storage container.

The resin layer coated on the inner surface of the outer cylindrical portion 1 and the inner surface of the bottom plate 5 is polyethylene resin (PE), polyester resin, acrylic resin, polyurethane resin, styrene resin, nylon resin (NY), poly It may be formed of a combination or laminate of a waterproof thermoplastic resin layer made of propylene resin (PP), cellophane resin or polyisocyanate.

At least one layer of the paper sheet laminate forming the inner surface of the bottom plate 5 is coated with the resin layer. The number of resin films laminated on one resin layer is not particularly limited, and may be, for example, about 2 to 5 layers. Various films have different densities and may be uniaxially or biaxially stretched or not stretched. However, if the type of resin is different, the film manufacturing method does not have a problem in particular. The thickness of the resin layer coated on the paper sheet is, for example, 10 µm to 200 µm.

In addition, when the resin layer is further coated with an inorganic oxide layer, the effect of preventing intrusion of outside air or moisture into the inside of the container is improved. Vacuum deposition is suitable as a means for coating the inorganic oxide layer. For example, alumina (Al ₂ O ₃ ), silica (SiO ₂ ) or titania (TiO ₂ ) can be preferably used as the inorganic oxide.

Even if the coating is performed, a problem may occur in that the filler coil is oxidized or rusted due to the material of the container. In particular, the oxidation or rust generation of the filler coil is caused by the oxidative component contained in the sheet layer on the inner surface of the outer cylindrical portion 1 in direct contact with the coil. In order to solve the above problem, the outer cylindrical portion 1 is formed of a stack of eight or more liner papers 1a to 1h, and the liner of at least one layer on the inner surface side of the outer cylindrical portion 1 It is formed from a low oxidation component eluting sheet. That is, the inner surface side of the outer cylindrical portion in contact with the welding wire is preferably formed of a paper sheet (paper layer) having an eluted chlorine ion concentration of 10 ppm or less and an eluted sulfate ion concentration of 80 ppm or less. That is, at least one layer of the liner 1a, or at least two layers of the liner 1a, 1b is formed of a low oxidizing component eluting sheet. It is preferable that the moisture content of the paper sheet layer is 15% or less. This further enhances the effect of preventing corrosion or rusting of the wire.

Similarly, the paper inner cylindrical part 6 has a problem that the filler coil is oxidized or rust is generated by the oxidative component contained in the sheet layer on the inner surface of the outer cylindrical part 1. Therefore, the outer surface side of the inner cylindrical portion in contact with the welding wire is formed of a paper sheet (paper layer) having an eluted chlorine ion concentration of 10 ppm or less and an eluted sulfate ion concentration of 80 ppm or less.

If the elution amount of the eluted chlorine ions from the low-oxidation component eluting sheet exceeds 10 ppm, there is a fear that rust occurs in the wire in contact with the eluted chlorine ions. In addition, when the concentration of the eluted sulfate ion exceeds 80 ppm, there is a fear that rust occurs in the wire in contact with the eluted sulfuric acid. In the present invention, attention has been paid to chlorine ions and sulfate ions which act particularly largely on corrosion and rust generation of wires as oxidative components contained in the constituent materials of the container. An oxidizing component in the _{^{other, F -, NO 2 -,}} Br - and the _{^{like, PO 4 3- -, NO 3}} . The influence of these oxidative components on corrosion or rust generation of the wire is considered to be minor.

The eluted chlorine ion concentration or the eluted sulfate ion concentration of the low oxidizing component eluting sheet is measured as follows, for example. That is, 5 g of the sample sheet is immersed in 100 ml of pure water and heated at 70 ° C for 30 minutes. Next, after removing the sample sheet from the solution, chlorine ions or sulfate ions obtained in the solution are quantified by ion chromatography spectrometry method. According to this measuring method, chlorine ions and sulfate ions are represented as 1/20 of the total concentration.

In this embodiment, even if the oxidizing component is contained in the component which is not in direct contact with the wire, it does not matter if the amount of the oxidizing component is similar to the amount contained in the conventional constituent material. However, it is more preferable that all the constituent materials forming the storage container do not elute the oxidizing component.

(Moistureproof in the cover part)

As shown in FIG. 24, when the welding wire in the receiving container is transported and stored, the circular cover 50 shown in the plan view of FIG. 26 covers the upper end 1y of the outer cylindrical portion 1. At this time, as shown in Figure 27, for the moisture in the cover portion, by placing the annular resin layer or rubber layer 45 on the inner surface side of the storage container of the outer edge portion 50a of the cover 50 to the outer cylindrical portion ( It is preferable to seal the inner surface side of the storage container of the upper end portion 1y of 1) and the outer edge portion 50a of the cover 50. It is preferable that the resin layer on the cover 50 is made of rubber or a stretchable resin, for example, a polyethylene stretchable in a resin. This is because elasticity is required for the resin layer on the cover 50 when the cover is opened and closed. In Fig. 27, reference numeral 1x designates the upper caulking portion of the outer cylindrical portion 1.

In addition, a spacer may be interposed between the welding wire coil 10 and the cover 50 inside the container. In this case, it is preferable that the low-oxidation elution sheet layer is disposed on the contact surface of the spacer and the wire. As a result, occurrence of rust in the wire is reliably prevented.

(Reinforced caulking part of outer cylinder part)

28 and 29 show an example of reinforcing the caulking portion of the outer cylinder portion of the storage container. FIG. 28: is sectional drawing which shows the principal part of the upper caulking part 1x and the upper end part 1y of the outer side cylinder part 1. FIG. FIG. 29: is sectional drawing which shows the principal part of the lower caulking part 1m and the lower end part 1n of the outer cylindrical part 1. As shown in FIG. 28 and 29, reference numerals 18a and 18b denote galvanized steel sheets provided on the upper caulking portion 1x of the outer cylindrical portion 1 and the lower caulking portion 1m of the outer cylindrical portion 1, respectively. Indicate (galvanized steel panel). These galvanized steel sheets 18a and 18b are arranged in an annular shape corresponding to the outer surface shape of each caulking portion and each end portion.

As described above, it is usually required to provide a constant pressure capacity for the outer cylinder 1. When using, storing and transporting a storage container, a large load is applied to each caulking portion or each end of the outer cylindrical portion. In addition, the laminated sheet is likely to be easily broken from each caulking portion or each end portion of the outer cylindrical portion in a damp or humid atmosphere. Therefore, in order to maintain and guarantee the pressure capacity of the outer cylindrical part 1, it is preferable to provide a galvanized steel sheet in each caulking part or each end part as mentioned above normally. At this time, in order to increase the corrosion resistance of the steel sheet itself, a galvanized steel sheet is provided. Corrosion-resistant coated steel sheets may be used instead of galvanized steel sheets, but are more expensive than galvanized steel sheets.

(Lifting sling)

30 and 31 are diagrams considering transportation by a crane or the like as a common problem in each embodiment of the wire welding container, showing an example in which a lifting sling is fitted onto the welding wire container. Fig. 30 is a view of the lifting sling, and Fig. 31 is a side view of the lifting sling when the lifting sling is fitted to the outer cylinder of the storage container. In Fig. 30, the lifting sling 51 is composed of a gripper (handle) 52 formed by combining a round bar with a lattice. The gripper 52 is pivotally supported by the upper horizontal lattice 52a as an axial portion to the bearing 53a of the dolly block 53 disposed on the outer surface of the outer cylindrical portion 1. have. On the other hand, in FIG. 31, the corresponding dolly block 55 is also disposed on the inner surface of the outer cylindrical portion 1. The dolly blocks 53 and 55 are firmly fixed to the outer cylindrical portion 1 by the rivets 54 so as to sandwich the outer cylindrical portion 1 therebetween. Four rivets 54 are arranged at four corners of the dolly block 53, and the dolly blocks 53, 55 are firmly fixed to each other through an insertion hole formed on the outer cylindrical portion 1 side. The rivets may be replaced by other known fastening means, such as bolts.

The example in which the lifting sling 51 is firmly fixed to the upper outer surface of the outer cylindrical portion is described above. However, the lifting sling 51 is not limited to this configuration per se, and other known dolly blocks may be suitably applied.

In the case where the lifting sling is provided, a bore hole in which the rivet 54 is inserted into the outer cylindrical part 1 is always required. Moreover, since an overload is applied on the hole by hanging the welding wire storage container, a gap is generated between the fastening means and the hole of the outer cylindrical portion. Therefore, the possibility of penetration of moisture and moisture into the storage container is increased through this gap. In addition, lifting slings should be made of iron or steel in view of their strength and durability. As a result, the outer lifting sling is likely to conduct electricity to the welding wire inside the containment vessel. If electrical conduction occurs during welding, there is a possibility of generating an electric shock or a spark. Therefore, for stability against electric shock or sparks, as shown in FIG. 31, it is preferable that the back side (inner side) portion of the outer cylindrical portion is coated with an electrical insulator to form the insulating layer 44.

(Cotton fastener for string fixation)

In the welding wire container according to the second embodiment of the present invention, it is more preferable that a surface fastener for fixing the string is provided.

32 is a cross-sectional view showing a welding wire receiving container having a strap fastening surface fastener according to an embodiment of the present invention. FIG. 33 is an enlarged plan view illustrating the surface fastener portion at the upper end portion of the string of FIG. 32.

As shown in FIG. 32, the lower end of the string 66 is hooked and fixed by the bottom 67 of the welding wire receiving container 80. The string 66 extends upwardly between the coiled stack of the welding wire 63 and the inner surface of the outer cylindrical portion 61 to close the gap between the retainer plate 64 and the inner surface of the outer cylindrical portion 61. To pass. The string 66 then extends through the inner surface side of the ring 65 to the upper end.

As shown in FIG. 33, the upper end of the string 66 is sealed to the loop side member 71 of the surface fastener 68, for example. The loop side member 71 of the surface fastener 68 is fixed to the hook side member 72 of the surface fastener bonded with a rubber adhesive, for example, on the upper inner surface of the outer cylindrical portion 61 of the welding wire receiving container 80. It is. The width of the loop side member 71 may be narrower, equal to, or wider than the width of the string 66. In addition, the upper end of the loop-side member 71 may or may not coincide with the upper end of the string 66. For example, the upper end of the loop side member 71 may protrude upward from the upper end of the string 66 or may be shorter than that. Bonding of the loop side member of the cotton fastener 68 and the string 66 may be performed by adhesive bonding or external stitching.

The ring 65 can be lowered together with the retainer plate 64. During the descent process, the strap 66 is held by the ring 65 to enclose the outer periphery of the wire 63 and the top surface of the retainer plate 64. By this action, the string 66 prevents the wire from protruding upward from the gap between the outer circumference of the retainer plate 64 and the inner surface of the outer cylindrical portion 61. The loop side member 71 and the hook side member 72 can be interchanged with each other.

The hook side member 72 of the surface fastener 68 is 10 mm-50 mm in width, and 50 mm-200 mm in length, for example. The hook-side member 72 is bonded and fixed along the inner circumferential direction of the outer cylindrical portion 61 by the number of strings 66. On the other hand, the loop side member 71 is 10 mm-50 mm in width, and is 10 mm-200 mm in length, for example. The loop side member 71 is fitted to the upper end of the string 66. The hook side member 72 may be disposed over the entire circumference of the outer cylindrical portion 61 along the inner circumferential direction of the outer cylindrical portion 61 of the welding wire receiving container 80. The surface fastener 68 has a loop side member and a hook side member like the surface fastener 30 shown in FIG. The loop-like protrusion of the loop-side member 71 and the hook-like protrusion of the hook-side member 72 are entangled with each other. As a result, the upper end of the string 66 can be fixed to the inner surface of the outer cylindrical portion 61.

Since the surface fasteners 68 are made of a flexible material, the surface fasteners 68 may be adhered along the inner surface of the welding wire receiving container. Therefore, even if the surface fastener is attached to the inner surface of the storage container by double-sided tape, the surface fastener does not fall. The protrusions of the hook side member 72 and the loop side member 71 are made of a single material or a composite material, such as nylon, polypropylene or polyester, for example.

Next, the operation of the welding wire storage container configured as described above will be described.

When the welding wire 63 falls in the loop shape in the welding wire receiving container 80, for example, three strings 66 are pulled upward along the inner surface of the outer cylindrical portion 61. Thereafter, the welding wire 63 falls inwardly of the outer cylindrical portion 61 in a coil shape in a state where the string 66 is fixed by the surface fastener 68. Next, after completion of the drop, the retainer plate 64 is placed on the welding wire coil. Thereafter, the string 66 is removed from the surface fastener 68, and the three strings 66 are passed through the inside of the ring 65, and then the ring 65 is placed on the retainer plate 64. Thereafter, the upper end of each string 66 is lifted upward, and the surface on which the loop side member 71 of the surface fastener fitted to the upper end of the string 66 is fixed to the upper inner surface of the outer cylindrical portion 61. It is in contact with and fixed to the hook side member 72 of the fastener 68. By the above configuration, the ring 65 can be lowered together with the retainer plate 64. During the descent process, the strap 66 is held by the ring 65 to enclose the outer periphery of the wire 63 and the top surface of the retainer plate 64. By this action, the string 66 prevents the wire from protruding upward from the gap between the outer circumference of the retainer plate 64 and the inner surface of the outer cylindrical portion 61.

Using a welding wire, the ring 65 held by the string 66 moves downward with the retainer plate 64 as the height of the welding wire stack decreases, preventing the wire 63 from popping out. do.

According to the present invention, since the upper end of the string is fixed by the surface fastener 68 to the upper portion of the outer cylindrical portion 61, the fixing force in the shear direction is large, and the string hardly comes off. In addition, since the surface fastener 68 is flexible, the adhesive property to the inner surface of the welding wire storage container is excellent and does not peel off. Therefore, the upper end of the string 66 can be securely fixed. Accordingly, there is no disadvantage in that the welding wire 63 cannot be supplied because the string 66 is pulled out. In addition, since the upper end of the string 66 is fixed by the surface fastener 68, the strap 66 is easily removed, and workability is improved.

In addition, the surface fasteners 68 can be used repeatedly, which is cheaper than conventional buckles and lowers running costs.

In the present invention, the hook side member 72 or the loop side member 71 of the surface fastener 68 is fixed to the inner surface of the outer cylindrical portion 61, for example, preferably using a rubber adhesive or a resin adhesive. However, the present invention is not limited to this configuration, and other adhesive means may be applied as long as they have the same adhesive force.

In the present invention, in contrast to the above embodiment, it is also possible to attach the loop side member to the outer cylindrical portion and to fix the string 66 on the hook side member.

The above detailed description of the preferred embodiment of the invention is for the purpose of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and modifications and variations may be made in light of the above teachings or may be obtained from practice of the invention. The examples have been chosen and described to illustrate the principles of the invention and its practical application so that those skilled in the art can use the invention in various embodiments and in various variations suitable for the particular use contemplated. It is intended that the scope of the invention be defined by the claims appended hereto and their equivalents.

According to the welding wire container of the present invention, it is possible to smoothly unwind the welding wire to the outermost layer of the welding wire without generation of entanglement or entanglement.
