The present invention relates to a welding wire reel (hereinafter simply referred to as "reel") for winding and storing welding wire (hereinafter simply referred to as "wire") and rewinding it for use. The wire is generally provided as a bare coil or as a coil wound on a reel or spool. Among these, the former bare coil disturbs the coil layer during transportation and is inconvenient to attach to a welding machine, so the latter reel or spool wound coil is often used, especially for small diameter wires. It is available as a reel or spool. On the other hand, these spools have traditionally been made of plastic from the viewpoint of moldability and cost, but these spools are usually disposed of without being recovered. However, when disposing of waste, for example, the incineration method generates harmful gases, and the landfill method requires securing a special site. Therefore, it is necessary to reconsider the previous disposal policy regarding spools. Furthermore, the prices of plastic raw materials have been rising, and there has been a demand for products that can be provided at lower prices. In order to meet these demands, Japanese Patent Application Laid-open Nos. 52-1275 and 56-66389 propose wire storage reels in which the spool take-up frame itself is made of metal wire. However, the proposed reel has the following drawbacks, and various problems arise when the wire is rewound and used. That is, the reel 1 has a winding frame itself composed of a metal wire 3 as shown in FIG. 1, but the metal wire 3 is a unit body as shown in FIG. Hereinafter simply referred to as "reel elements") 4 are connected. The reel element 4 also includes a wire support portion 4a for supporting a wire, a first side portion 4b extending parallel to the outside from both ends of the wire support portion, and holding a reel from the first side portion. an outer rim portion 4c extending parallel to the circumferential direction of the shaft; and a second side portion 4d extending parallel to the outer rim portion inwardly.
and a shaft stop portion 4e whose both ends of the second side portion are connected parallel to the reel axis. Therefore, the continuous portion of the wire support portion 4a and the first side portion becomes a corner portion A having a curved surface R. Therefore, when a wire is wound around the corner A, the following wire digging phenomenon occurs. This phenomenon is particularly noticeable for wires with a small diameter. That is, FIGS. 3 to 5 show explanatory diagrams of the state in which the wire is wound around the wire support member 4a in sequence. In FIG. , are wound in a well-aligned manner up to the starting point of the curved surface R at the corner A. Then the wire a p is wound up to point P
The wire a1 that is wound next is initially located above the curved surface R, but due to the action of the winding tension (so-called back tension) of the wire, it moves downward along the curved surface R, and as shown in FIG. As shown, insert it between the wire a p and the wire support member 4a. In this case, the wire in the lowest layer has no choice but to protrude outward, but not only the protruding wire ap , but also a wire at an arbitrary position that has been wound before the wire ap may protrude. In any case, if wire a 2 is wound next to wire a 1 under such conditions, wire a 2 will be in a position as shown in FIG. 4, and the bottom layer of the wire will be disordered at corner A. If the wires are continued to be wound and stacked in this state, the stacked state of the wires will be reversed at corner A as shown in Figure 5, and an excessive tensile force will be applied when the wires are unwound. This causes the wire to be bent, making it difficult to feed the wire, and in the worst case scenario, the wires become entangled, causing the wire to stop feeding. The present invention has been developed in view of these circumstances, and its purpose is to prevent the above-mentioned wire digging-in phenomenon and maintain a good wire stacking state on the wire support portion, thereby preventing wire winding. The objective is to provide a reel that can be reliably and easily returned. However, the reel of the present invention that has achieved these objects is a reel that is made by arranging a plurality of reel elements formed by bending a single metal wire in a circular shape and connecting them to each other. The element includes a wire support portion for supporting a wire, a first side portion extending parallel inwardly from both ends of the wire support portion, and a circumferential direction of a shaft holding the reel from the first side portion. an inner rim portion extending parallel to the inner rim portion; a second side portion extending parallel outwardly from the inner rim portion; and a second side portion extending parallel to the first side portion from the second side portion. The gist lies in that it is constructed from an extending outer rim portion. The configuration and effects of the present invention will be explained below based on the drawings, but the drawings merely show one representative example, and the present invention is not limited to the illustrated example. Partial design changes such as reel elements and reel element shapes are within the technical scope of the present invention. FIG. 6 is an explanatory diagram of the reel element 5 according to the reel of the present invention, and as shown in this figure, the reel element 5 includes a wire support portion 5a and a wire support portion 5a extending inward in parallel from both ends of the wire support portion 5a. a first side portion 5b; an inner rim portion 5c extending from the first side portion 5b in parallel to the circumferential direction of a shaft (not shown) for holding the reel; and the inner rim portion a second lateral portion 5d extending parallel outward from 5c;
and an outer rim portion 5e extending in parallel from the second side portion 5d in a direction on the extension line of the first side portion 5b.
It consists of When a plurality of reel elements 5 having such a configuration are arranged and connected in a circular shape to complete a reel, the wire support portion 5a is attached to the second side portion 5'd of the adjacent element 5' as shown in FIG. The corner A' that abuts and is created by the intersection of the wire support portion 5a and the second side portion 5'd is approximately at a right angle. Therefore, the phenomenon of wire digging in at the corner A' is completely eliminated, and the wires are laminated on the wire supporting portion 5a in an orderly manner. When an experiment was conducted to compare the performance of the conventional reel and the reel of the present invention, good results were obtained as shown in Table 1 below.

廃却に対し有利である。[Table] That is, as is clear from Table 1, the reel of the present invention can be satisfactorily applied to wires having a small diameter of 1.0 mmφ or less. In addition, as shown in FIG. 8, the reel element 5 is configured so that, in addition to the above configuration, both ends of the outer rim portion 5e extend inwardly in parallel to the extension line of the first side portion 5b (i.e., By adding the third side part) 5f, it becomes possible to use the third side part 5f as the welding point that connects each reel element, and the side part of the completed reel consists of approximately two wire rods. Since it is in a bundled shape, the wire holding strength is increased, and the amount of deformation due to impact when dropped is also extremely small. Furthermore, if a stepped portion 5g is formed in the continuous portion of the outer rim portion 5e and the second side portion 5d as shown in FIG. 9, even if there are variations in the length of each outer rim portion 5e, these variations will be Since it is absorbed by the stepped portion 5g, the permissible accuracy of the reel element 5 is somewhat relaxed. That is, when each reel element 5 is arranged in a circular shape and welded together,
Each second side portion 5d and the first side portion 5b of the adjacent reel element 5' are forced into contact, but in this case each outer rim portion 5e and each second side portion If the step portion 5g is formed in the continuous portion of the outer rim portion 5d, even if the lengths of the outer rim portions 5e are uneven, the outer rims 5e overlap each other at the step portion 5g, so that these are forcibly reinforced and deformed. There's no need. Therefore, it goes without saying that the reel can be completed with only a simple welding operation, and there is no unnecessary strain or local internal stress on the reel, and there is no possibility that the reel will be deformed during winding or storage of the wire. Further, as a welding method for joining each reel element, any of the various solution methods currently in use can be applied, but spot welding is particularly preferred. In other words, spot welding does not use filler metal,
Since only crimp terminals for welding are used, a plurality of welding parts can be simultaneously welded after each reel element is assembled and arranged, resulting in less thermal distortion of the reel and efficiency. After combining an appropriate number of each reel element to form one reel 6 as shown in FIG. 10, the reel is coated with an appropriate paint or coating from the viewpoint of rust prevention and appearance, as in the past. Just do it. However, when this reel is used to feed the wire, it is necessary to previously fit an insulating hollow cylinder onto the reel shaft of the wire feeding device, as in the conventional case. Therefore, by coating the entire reel 6 obtained by applying paint or polishing as described above with a resin such as polyethylene to impart insulation properties to the reel 6 itself, it is possible to create a hollow cylindrical body for insulation as in the past. This eliminates the need for the reel, and it can be directly attached to the reel shaft of the wire feeder, and compatibility with other plastic reels and the like is also improved. Incidentally, if the thickness of the above-mentioned insulating coating is 0.1 mm or more in the case of a coating made of polyethylene resin, the insulation property can be maintained sufficiently well. Since the present invention is roughly constructed as described above, various effects summarized below can be obtained. Since the so-called wire digging phenomenon does not occur at both ends of the wire support portion of the reel, the wire stacking state on the wire support portion is well maintained, and the wire can be rewinded reliably and easily. At the same time, the wire can be fed smoothly. The wire to be wound is of a small diameter (1.00mmφ
(below) is applicable. Unlike conventional reels, there is no need to insert an electrical insulator with a bearing into the body when winding the wire, and it can be directly attached to the reel shaft of the wire feeder, making it compatible with plastic reels and plywood reels. Compatibility can be ensured. It is possible to create an inexpensive reel for welding wire. It is advantageous for disposal.
