Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel wire, a steel cord,
The present invention relates to an improvement in a reel for winding a metal wire such as a wire rope and an electric wire. 2. Description of the Related Art Conventionally, as a structure for winding a metal wire on a reel and fixing the end of the metal wire when it is fully wound, as shown in FIG. Small hole 12 on outer circumference
Is generally provided with a locking member 13 made of a steel wire, a leaf spring, or the like on the outer surface of the flan in close proximity to the small hole 12, and a metal wire end W extending from the small hole 12.
Is held between the locking member 13 and the outer surface of the flange. Another method is disclosed in Japanese Utility Model Publication No. 59-733.
As shown in FIG. 7, in Japanese Patent Publication No.
1a, a notch groove 22 is provided, and a locking member 23 is provided on the outer surface of the franc in the vicinity of the notch groove 22. The metal wire end W is cut through the notch groove 22 to form a locking member 23. It was designed to be clamped between the franc and the outer surface. [0004] In the former case, it takes time and effort to pass the end portion W of the metal wire into the small hole 12, and also takes time to take out the end portion when the wire is unwound. It takes. Further, when the metal wire is a stranded wire such as a steel cord or a wire rope, the ends are separated, so that the small holes 12 are formed.
Therefore, there is a problem that it is difficult to pass through the wire, and therefore, it is necessary to wind the end portion with a tape or to melt the wires so that the wires are welded to each other, so that the operation is very complicated. [0005] In the latter case, there is no need to pass the metal wire end W through the small hole, so that the work efficiency is improved.
However, since the notch groove 22 is provided, the franc strength at that portion is greatly reduced, and the franc skew occurs due to the side pressure generated when the metal wire is wound around the reel. For this reason, the wound shape of the striated body has been broken or the life of the reel has been shortened. [0006] In both of the above-mentioned structures, the end of the metal wire after locking is protruded outside the reel ヂ. If the end of the metal wire protruding from the franc is damaged in the plastic packaging at the time of packing, or if the reels are stored side by side or stacked, franc ヂ hits the end of the protruding metal wire and locks. If it came off, a problem occurred. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and can easily lock and release the end of a metal filament without shortening the life of the reel. It is an object of the present invention to provide a reel for winding a metal filament which does not protrude outside the reel. [0008] In order to solve the problem, a reel according to the present invention eliminates a small hole that has been passed through the end locking member before the metal wire is clamped. The locking device was attached to the inside of the flange, and a small hole was made to guide the end of the metal striatum into the curl cavity of the flange. More specifically, in a metal wire winding reel provided with a furan having a curled portion whose outermost peripheral portion is bent outwardly at both ends of the copper wire as described in claim 1, at least one of the furans near the outer periphery of the inner surface of the furan. At the point, the tip is bent slightly outward along the outer peripheral edge of the franc, and a small gap is provided between the outer peripheral edge of the franc and an elastic end locking device is attached. A small hole from the inner surface of the flan to the curl cavity was provided near the end locking device. The metal wire is wound on a reel, and the end of the metal wire when fully wound is provided near the outer periphery of the inner surface of the flan. The end of the metal wire is fixed by the elasticity of the end locking member by being sandwiched in a small gap between the flange and the flange, so that the winding is not unwound. Further, by passing the end of the metal wire through the small hole into the cavity of the furan / curl portion, the protrusion from the outer periphery of the furan is prevented. Further, at the time of wire breaking, the wire can be easily broken only by pulling the end of the metal filament in the direction opposite to the locking direction of the end locking member. Further, by bending the tip of the end locking member slightly outward along the outer periphery of the flank, the metal wire can be caught on the tip of the end locking member at the time of reel winding or reeling out. Can be prevented. Embodiments of the present invention will be described below with reference to the drawings. (Embodiment) As shown in FIG. 1, an end locking member 3 is attached and locked in the vicinity of the outer periphery of the inner surface of a franc # 1 in a reel for winding a metal wire having furans # 1 provided at both ends of a winding drum 2. The small hole 4 which leads to the franc curl part cavity is provided near the tool,
A reel for winding a metal wire of the present invention was produced. As shown in FIG. 2, the end locking member 3 was formed by bending a thin metal elastic plate having a thickness of about 1 mm at the tip. This end locking device 3 is connected to a franc {outer rim 1a}.
And a small gap was provided between them, and the root and the flange were attached by spot welding. The position of the small hole 4 leading to the curl cavity 5 is shown in FIG. Flang around end locking member 3 outer peripheral edge 1
As shown in FIG. 3, a was ground with a grinder and slightly dented. By doing so, the end locking member 3 can be provided without protruding from the outer circumference of the franc. Therefore, even when the reel is rolled, the end locking member 3 does not hurt. Of course, even if the outer periphery 1a of the furan is not recessed as shown in FIG. 3, it does not affect the operation and effect of the present invention at all. Using the reel created as described above, FIG.
As shown in the figure, the metal filament was actually wound up. The end portion W of the metal wire was fitted into the gap between the end locking member 3 and the outer periphery 1a of the furan, and then pulled toward the center of the reel to be pinched and passed through the small hole 4. The metal wire end W was firmly held by the elasticity of the end locking member 3, and the metal wire end entered the curl cavity 5 and did not protrude outside the reel. Next, it was confirmed that the wire can be easily broken by pulling out the end portion W of the metal wire by the reverse operation of the above procedure. It should be noted that excessively large bending at the end of the end locking member is not preferable because the operation at the time of locking and unwinding increases. Therefore, it is sufficient that the metal wire is bent so as not to be caught on the tip of the end locking member at the time of reel winding or feeding. Spacers are used by inserting spacers. Although a metal elastic plate is used as the material of the end locking member, an elastic linear body may be used instead. In addition, the elastic plate or elastic striated body is processed into an uneven shape, a wavy shape,
The metal filament W may be fitted into the recess. Further, the material of the end locking member is metal in the embodiment, but the same effect can be obtained by using an elastic body such as reinforced plastic or glass fiber instead.
However, regardless of which material is used, it is important to use a material having sufficient strength and elasticity to withstand the bending of the end locking member generated when the metal wire end W is clamped. Further, as a means for attaching the end locking member to the flange, spot welding is used in the embodiment, but other methods such as rivets and bolts or a method using an adhesive can be adopted. These mounting methods may be appropriately selected in consideration of the materials of the end locking member and the flange. According to the present invention having the above-described structure, it is not necessary to pass the end portion of the metal wire through the small hole as in the prior art. There is no need to weld the wires together. Therefore, the end locking operation and the unwinding operation are greatly simplified. Further, the ends of the metal filament do not protrude from the reel flan, so that the packaging is not damaged, and the flan is prevented from hitting the metal filament and being disengaged. Further, there is no need to provide a notched groove in the outer peripheral edge of the furan, and there is no distortion of the furan caused by the notch.
Therefore, the life of the reel is not reduced, and the winding shape of the metal filament is not broken.
