BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for bundling wire coils made of carbon steel, alloy steel, stainless steel, etc., wound into coils.

[Prior Art and Problems to be Solved by the Invention] Wire rods made of carbon seam steel, alloy steel, stainless steel, etc. are wound into coils and bundled for temporary storage or transportation. things are being done. It is desirable to bundle the wire coils as tightly as possible to prevent them from collapsing during storage or transportation. Conventionally, when binding such wire coils, iron hoops are used, and the hoops are wound vertically around the coil at a suitable number of circumferential locations (usually 4 locations) and drawn to form a wire coil. Both ends were joined in a compressed state.

However, when an iron hoop is used, there is a problem in that the edges at both ends of the hoop may damage the bundled wire rods or other wire coils when they hit, so when using such an iron hoop, it is necessary to Place laminated paper on the wire coil, wrap a steel hoop over the laminated paper and tie it together, place cardboard paper under the iron hoop joint, or apply packing tape over the joint at both ends of the hoop. This prevents the steel hoop from damaging the wire. Alternatively, as shown in FIG.
It has also been considered to place a pad 102 on the underside of the end joint of the iron hoop 100 to prevent the end of the hoop 100 from damaging the wire 104 (this is a proposal by the applicant). ).

[0004] However, such a process is troublesome and complicates the bundling work. Therefore, it has been considered to use a resin hoop as a binding hoop, and it is possible to use such a resin hoop as a binding hoop if it is actually a lightweight wire coil with a total weight of up to about 300 kg. However, when it comes to large wire coils weighing more than 1 ton, when compressing the wire coil using such resin hoops, the hoops break due to the low tensile strength of the resin hoops, making it difficult to actually bundle them. It is difficult to do this.

When binding wire coils using a resin hoop, a cylinder 10 as shown in FIG. 4 is used to ensure good binding even in the case of small wire coils.
A wire coil is compressed from both sides in the axial direction using a compression device 108 including a wire coil 108, and the wire coil is bound by a hoop 110 under the compressed state by the compression device 108. However, when compression is performed using such a compression device 108, especially when the coil is large and weighs nearly 1 ton, the force applied to each part of the coil may be uneven and the wire may be damaged. There is also the problem that the wire is difficult to gather into a good coil shape, and the wire may come apart later.

[0006]

[Means for Solving the Problems] The present invention has been made to solve the above problems, and its gist is to use a resin hoop as a binding hoop, and to connect the resin hoop to a wire coil. When binding the coil by winding it in the vertical direction perpendicular to the winding direction of the wire at a predetermined point in the circumferential direction and joining both ends, a flexible wire such as fiber rope that is softer than the wire and has sufficient tensile strength is used. Using the flexible wire body as an auxiliary means for binding, the flexible wire body is wound vertically around the wire coil and drawn, thereby compressing the wire coil in the axial direction. The resin hoop is joined at a location adjacent to the drawn portion of the body, and then the drawn portion of the linear body is released.

[Operation and Effects of the Invention] As described above, the present invention does not use a resin hoop for binding itself to pull the wire coil in the compression direction, but instead uses a fiber rope such as a nylon sling or other soft flexible material. A wire coil is drawn in the compression direction using a wire body, and then bound with a hoop under a sufficiently compressed state. Therefore, even if a resin hoop having a lower tensile strength than an iron hoop is used, the wire coils can be tied together well, and each wire can be tightly tied in a sufficiently compacted state.

[0008] This resin hoop also has the advantage that there is no risk of damaging the wire coil, and for this reason, it is necessary to dispose of the hoop end from the upper side of the hoop end, which was conventionally required when using an iron hoop. There is no need to apply duct tape or put corrugated paper on the underside of the hoop, or put a pad on the underside of the hoop end, or put laminated paper on the underside of the hoop to prevent scratches. This eliminates the need for intervening materials, making it easier to bundle wire coils. Furthermore, in this method, the wire coil can be compressed without using a compression device as shown in FIG. 4, so the wire coil can be packed well, and the problem of the coil losing its shape later can be avoided.

Embodiments Next, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 3, reference numeral 10 indicates a wire coil formed by winding a wire of carbon steel, alloy steel, stainless steel, etc. into a coil shape, and reference numeral 12 indicates a resin that binds the wire coil 10 at four locations in the circumferential direction (winding direction). It is a made hoop. The wire coil 10 is a large coil with a total weight of about 1 ton in this example, and correspondingly, a wide resin hoop 12 with a width of about 32 mm is used. Although this resin hoop 12 does not have enough tensile strength to pull the wire coil 10 in the compression direction by itself, it has sufficient strength to bind the wire coil 10 in a compressed state and maintain that state. ing.

FIG. 1 shows the procedure for bundling the wire coils 10 using the resin hoop 12. As shown in the figure, this binding method uses a nylon sling 14 as an auxiliary means for binding. To be more specific, in the method of this example, as shown in FIG. 2, two nylon slings 14 are passed through the wire coil 10 in the vertical direction at two opposing positions, and the two nylon slings 14 are passed through the wire coil 10 at two opposing positions. Apply force in the direction shown to tighten it. Then wire coil 1
Since the tightened portion of 0 is sufficiently compressed in the axial direction, the nylon sling 14 as shown in FIG.
Resin hoop 1 at the location adjacent to the drawing location due to
2 is wound around a wire coil 10, and both ends thereof are joined. The ends of the resin hoop 12 can be joined by heating them to about 500° C. and fusing them together.

After binding with the resin hoop 12 in this manner, the wire coil 10 is unfastened by the nylon sling 14, and then the wire coil 10 is tied at 90 degree intervals in the circumferential direction from the binding position with the hoop 12. The same operation as above is performed at only two opposing positions to bind the coil 10 at the other two positions. As a result, a bundle of wire coils 10 as shown in FIG. 3 is obtained.

[0012] When the wire coils 10 are bundled as described above, the resin hoop 12 is made of a material that is sufficiently soft to the wire and there is no risk of damaging the wire.
For this purpose, a material to prevent the wire from being damaged is interposed under the resin hoop 12, and the edge of the resin hoop 12 is prevented from hitting and damaging other wires. There is no need to clean up the wire rod coils 10, and the work of bundling the wire rod coils 10 becomes easy, and the packaging becomes beautiful. Further, according to this method, the wire rod coil 10 can be bundled sufficiently tightly, and therefore, the wire rod can be prevented from coming apart or losing its shape during temporary storage or transportation. Furthermore, when tightening the wire coil with the nylon sling, if the angle A at which the nylon slings intersect is set to 90 degrees or more as shown in FIG. Therefore, the wire coil 10 can be tied more precisely.

[0013] Although the embodiments of the present invention have been described in detail above, this is merely an example, and in the present invention, for example, instead of the above-mentioned nylon sling, it is also possible to use a fiber rope or string-like body made of other materials. . In short, any flexible material that does not cause damage to the wire and has sufficient tensile strength can be used.

Furthermore, the present invention is highly effective when applied to binding large wire coils weighing nearly 1 ton;
Of course, it can be applied to the bundling of small wire rods of about kg or less, and the radial cross-sectional shape of the wire coil is not limited to a rectangular shape as in this example, but can also be applied to circular or elliptical shapes. Therefore, the present invention can be applied to compress a wire coil by a flexible wire body by winding it around the coil multiple times and then tightening the coil. It can be implemented with various modifications based on knowledge.
