Description

  The present invention relates to a welding wire with a pail pack in which a twisted solid wire or a welding wire of a flux-cored wire is stacked and stored in a loop shape.

  A pail pack is generally used as a container for a 200 to 350 kg welding wire. Especially when used in large quantities, a plurality of pail packs are arranged side by side, and the welding wire end of the preceding pail pack and the welding wire starting end of the next pail pack are connected by butt welding for continuous use. Has been.

  As the technique of continuous use, there is one disclosed in, for example, Japanese Patent Publication No. 3-33434 (Patent Document 1). Here, as shown in FIG. 3, the terminal portions 6 of the welding wires laminated are guided upward along the outer peripheral surface of the wire laminate 9 and the inner wall 2 of the pail pack, and through the lower portion of the annular pressing plate 4. The welding wire terminal 6 of the preceding pail pack 1 and the welding wire starting end 7 of the pail pack 1 to be used next are connected by butt welding and used continuously. The welding wire is taken out from the inner side 5 of the pressing plate 4 along the inner periphery of the pressing plate.

  Further, as described in Japanese Utility Model Publication No. 64-4764 (Patent Document 2), the technique described above prevents the wire on the wire laminate 9 from jumping up from between the pail pack inner wall 2 and the pressing plate 4. It is often used in combination with a technique in which the string member 8 is provided. The upper end of the string member is fixed to the upper portion of the pail pack inner wall 2, and is suspended between the pail pack inner wall 2 and the outer periphery of the wire laminate 9 through a hole provided in the holding plate 4.

  By the way, the welding wire terminal portion 6 is guided upward along the outer peripheral surface of the wire laminate 9 and the inner wall surface 2 of the pail pack, and then taken out from the inner side 5 of the pressing plate 4 through the lower portion of the pressing plate 4. The wire terminal portion 6 is fixed to the inner surface wall of the pail pack above the pail pack 1 by a holder 3 such as an adhesive tape or a fixing jig. Therefore, as shown in FIG. 4, as the amount of the welding wire decreases, the welding wire guided upward along the outer peripheral surface of the wire laminate 9 and the inner wall surface 2 of the pail pack becomes loose. And the wire between the upper surface of the wire laminated body 9 and the lower surface of the pressing plate 4 protrudes from between the inner wall surface 2 of the pail pack and the outer side of the pressing plate 4 between the string member 8 and the string member. There is a case.

As shown in FIG. 5, the protruding welding wire A portion has the loosened welding wire hinders the fall of the pressing plate 4 as shown in FIG. 5, and the welding wire is located between the pressing plate 4 and the wire laminate 9. The welding wire may jump out and become unable to feed the welding wire.
Japanese Patent Publication No.3-3334 Japanese Utility Model Publication No. 64-4764

  In the present invention, when welding wires stored in a plurality of pail containers are used continuously, the welding wire does not jump out from between the holding plate and the wire laminate, and is smoothly taken out and welded. It is an object to provide a welding wire with a pail pack that can be fed to a part.

The gist of the present invention is that, in a welding wire containing a pail pack in which welding wires are stacked and accommodated in a loop shape and an annular pressing plate is placed on the upper end of the loop, the end of the welding wire is the outer periphery of the wire laminate For welding with a pail pack, characterized in that it is guided upward along the surface, taken out from the inside of the annular pressure plate and fixed at a plurality of ends of the welding wire in the horizontal direction at the upper part of the inner surface of the pail pack. On the wire.
Moreover, the terminal part of the welding wire is also characterized in that a plurality of lengths of 400 mm or more are secured in the horizontal direction at the upper part of the inner surface of the pail pack.

  According to the welding wire with a pail pack of the present invention, when the welding wires housed in a plurality of pail containers are continuously used, the welding wire jumps out from between the holding plate and the wire laminate. It can be taken out smoothly and fed to the weld.

  FIG. 1 is a partially broken perspective view showing a state in which a welding wire is taken out of the welding wire with a pail pack of the present invention. The welding wire twisted into the pail pack 1 is stacked and accommodated in a loop to form a wire laminate 9, and a pressing plate 4 is placed on the upper surface of the wire laminate 9 to prevent the welding wire from jumping up. .

  A plurality of string members 8 are provided to prevent the wire on the wire laminate 9 from jumping up between the pail pack inner wall 2 and the pressing plate 4. These string members are fixed between the pail pack inner wall 2 and the outer periphery of the wire laminate 9 by fixing the upper end to the upper part of the pail pack inner wall 2 and inserting the hole provided in the holding plate 4. .

  The welding wire terminal portion 6 is guided upward from the bottom of the pail pack 1 along the outer peripheral surface of the wire laminate 9 and the inner wall surface 2 of the pail pack, and then the inner side 5 of the press plate through the lower portion of the press plate 4. The wire terminal portion 6 is fixed to the inner surface wall of the pail pack by a holder 3 such as an adhesive tape or a fixing jig above the pail pack 1. The welding wire 7 is sent along the inner side 5 of the pressing plate from a wire take-out device or a wire guide member (not shown) to the wire feeding device and taken out.

  Since the welding wire terminal portion 6 is fixed at a plurality of locations (3a, 3b, 3c) in the upper horizontal direction of the pail pack inner wall surface 2, as shown in FIG. When the use of the welding wire progresses between the inner sides 5 and the presser plate 4 descends, a force in the a direction acts due to the rigidity of the wire, and the wire is pulled in the b direction. For this reason, the welding wire led upward along the outer peripheral surface of the wire laminate 9 and the inner wall surface 2 of the pail pack does not loosen. Therefore, the wire protrudes from between the inner wall surface 2 of the pail pack and the outside of the press plate 4 and does not obstruct the fall of the press plate 4, so that the welding wire jumps out from between the press plate 4 and the wire laminate 9. There is nothing.

  In addition, it is preferable to fix the terminal portion 6 of the welding wire at a plurality of locations with a length of 400 mm or more in the horizontal direction of the inner surface of the pail pack because rigidity of the wire is increased. In addition, the same effect can be obtained by fixing the terminal portion 6 of the welding wire by fixing the entire length of 400 mm or more in the horizontal direction of the inner surface of the pail pack with an adhesive tape or the like. However, this makes it difficult to remove the welding wire end 6 from the inner surface of the pail pack when butt welding the welding wire end 6 of the preceding pail pack 1 and the welding wire start 7 of the pail pack 1 to be used next. Therefore, it is preferable that the fastening length of one place is about 30 to 80 mm.

  When the use of the welding wire proceeds and the presser plate 4 descends as in the prior art shown in FIG. 2B, the wire is pulled in the c direction between the fastening portion 3 and the inner side 5 of the presser plate. At this time, if the terminal end 6 of the welding wire is fixed at one location or a plurality of locations with a length of less than 400 mm in the horizontal direction of the pail pack, the c direction such as the force in the direction a in FIG. The force for canceling the force does not work, and the welding wire led upward along the outer peripheral surface of the wire laminate 9 and the inner wall surface 2 of the pail pack is loosened. For this reason, the wire protrudes from between the inner wall surface 2 of the pail pack and the outer side of the pressing plate 4 as shown in part A of FIG. 2C to prevent the pressing plate 4 from falling, and the welding wire is pressed between the pressing plate 4 and the wire. Tangles may occur by jumping out from the laminate 9.

  A solid wire (JIS Z3312 YGW11) with a wire diameter of 1.2 mm is twisted in a loop shape in a loop shape of 280 to 320 ° per turn, 200 kg for a pail pack inner diameter of 500 mm, and a pail pack inner diameter of 650 mm. 300 kg stacked and stored.

  As shown in Table 1, the number of ends of the welding wire and the length thereof were changed, and the welding wire was fixed in the upper horizontal direction of the pail pack inner surface. An adhesive tape having a width of 50 mm was used for fixing the end of the welding wire.

  In each test example, the wire was taken out at a wire take-off speed of 15 m / min for 100 minutes, and the presence / absence of wire protrusion from the inner wall of the pail pack and the outside of the pressing plate and the occurrence of tangles were examined. The results are also shown in Table 1.

  In Table 1, test no. 1-4 are examples of the present invention, test Nos. 5 to 7 are comparative examples. Test No. which is an example of the present invention. 1-4, since there are a plurality of fastenings at the end of the welding wire and the fastening length exceeds 400 mm, even if the welding wire is taken out and the presser plate is lowered, the welding wire depends on the rigidity of the wire. Will not sag. Therefore, the wire did not protrude from between the inner wall surface of the pail pack and the outer side of the pressing plate, and it did not jump out between the pressing plate and the wire laminate, which was a very satisfactory result.

  Test No. in Comparative Examples. In No. 5, the welding wire is loosened when the welding wire is taken out and the presser plate is lowered because the end of the welding wire is fixed at only one point. For this reason, the wire protruded from between the inner wall surface of the pail pack and the outer side of the pressing plate to prevent the pressing plate from falling, and the welding wire jumped out between the pressing plate and the wire laminate, resulting in entanglement.

  Test No. 6 and 7, since the fastening length of the end of the welding wire is short, the welding wire is loosened when the welding wire is taken out and the holding plate descends, and the wire is loosened between the inner wall surface of the pail pack and the holding plate. Projected from outside.
