Abstract

PURPOSE:To suppress occurrence of scratches on each wire rod surface and loose bundles by fitting adjacent wire rods to one another by oscillation and clamping bundle hoops perpendicularly to a winding direction of the wire rods. CONSTITUTION:Prior to clamping bundle hoops 3a to 3d, oscillation for fitting wound and adjacent wire rods 31 to one another is performed. After the adjacent wire rods 31 are fitted to one another by this oscillation, then the bundle hoops 3a to 3d are clamped perpendicularly to a winding direction of the wire rods 31. Therefore when the wire rod 31 wound in a ring is to be bundled, bundling of a wire rod coil can be sufficiently well while occurrence of scratches due to pressing between the wire rods is prevented. Thus occurrence of loose bundles wherein bundling of the wire rods is loosened during storage, transportation, etc. and such a failure that the outer diameter of the wire rod coil 31 is disturbed can be suppressed.

Description

[Detailed description of the invention]

[Purpose of the Invention (Field of Industrial Application) This invention relates to carbon steel. Alloy steel. This invention relates to a wire coil binding method suitable for temporarily storing and transporting wire rods such as stainless steel wire rods, which are formed into coils and then tied together to form wire rod coils. (Conventional technology) Conventional. When temporarily storing or transporting wire rods made of carbon steel, alloy steel, stainless steel, etc., these wire rods are usually wound into coils and bound with binding hoops to form wire coils. For such wire coils, ■ the filling rate is high and the binding is tight; ■ the coil thickness is uniform from the tip to the rear; ■ the outer diameter is flat with no irregularities. It is desirable for the coil to be packaged so that it is not tangled, and that the ends are easy to take out.If the outer diameter of the coil is irregular, it will be difficult to store and transport the coil in stacks. This makes it easy for the surface of the wire to become scratched during transportation. Also, if the coil is not tightly packed, the packaging will be disordered and it will be difficult to pickle or anneale the coil while it is still in the coil state. Furthermore, poor winding properties such as tangles in the wire can lead to problems such as reduced wire drawing efficiency and wire breakage, which significantly impedes work efficiency. For this reason, wire rod manufacturing equipment requires various considerations regarding the packaging shape from winding to tying, such as the ring diameter in the winding machine, the structure of the coil convergence device, the bresker, binding material, and number of binding points in the binding device. is being done. FIG. 4 shows an example of a conventional wire coil,
This wire rod coil 31 has iron binding hoops 33a made of band-shaped high-tensile steel strips or the like in a direction perpendicular to the winding direction of the wire rod 32 at multiple locations in the winding direction of the wire rod 32, that is, four locations at 90° intervals. ．． It is made by tightening 33b, 33c, and 33d one time. In addition to using iron binding hoops (33a to 33d), there are also types of binding using wire such as annealed iron wire or mild steel wire. Furthermore, in addition to small bundles that bind one coil together, large bundles that bundle large coils together may also be used. Figure 5 shows the wire coil 3 shown in Figure 4 by horizontal bundling.
1. This horizontal wire rod binding device 41 includes a fixed anvil 43, a movable anvil 44, and a hydraulic cylinder 4 on a base 42.
5 and two rotating rolls 46 placed in parallel.After the wire coil 31 is placed a on the rotating roll 46, the piston rond 45a of the hydraulic cylinder 45 is operated to push it out in the direction of the arrow. The movable anvil 44 is moved to compress the wire coil 31 between the movable anvil 44 and the fixed anvil 43, and first, the band-shaped iron binding hoop 33a. 3
3c, the rotating roll 46 is rotated to rotate the wire coil 31 906 times, and then the band-shaped iron binding hoop 3 is wound at two opposing positions, that is, the left and right positions.
3b and 33d are wound together to form the wire coil 31 shown in FIG. Figure 6 shows the wire coil 3 shown in Figure 4 by vertical bundling.
1, this vertical wire rod binding device 51 has a hydraulic cylinder 53 at the top of a frame 52, and a rotary table 52 at the bottom of the frame 52. The rotary table 5 is rotated by a gear 54, a transmission member 55, a gear 56, and a motor 57, and a compression plate 58 is provided on the piston rod 53a of the hydraulic cylinder 53. Then, the wire coil 31 is laid down and placed on the rotary table 5, and then the piston rod 53a of the hydraulic cylinder 53 is pushed out in the direction of the arrow to lower the compression plate 58, and the rotary table 5 is
The wire rod coil 31 is compressed between the wire rod 9 and the compression plate 58, and band-shaped iron binding hoops (33a to 33d) are wound and tightened to form the wire rod coil 31 shown in FIG. (Problem 8 to be Solved by the Invention) However, in such a conventional method of bundling wire coils 31, the wire coils are bound by the movable anvil 44 shown in FIG. 5 and the compression plate 58 shown in FIG. Even if the wire rods 31 are pressed, it is difficult to press them due to the overlap of the wire rods 32 of this wire rod coil 31 in the aligned winding state, and the wire rods 32 are pressed even harder to insert the wire rods 32 into the gaps between the wire rods 32 to create a dense state. If the wire rods 32 rub against each other, scratches may easily occur, so the wire rods 32 are pressed with a pressing force that does not generate such scratches, and the wires are wrapped with the binding hoops 33a to 33d. In some cases, it may not be possible to securely bind the product, which causes the problem that the binding may become loose during storage or transportation, resulting in a loose bun. (Purpose of the Invention) This invention was made in view of the above-mentioned problems in the prior art. The purpose of the present invention is to provide a method for bundling wire coils that prevents the occurrence of loose bundles and suppresses the occurrence of loose bundles. [Structure of the Invention] (Means for Solving the Problems) The present invention provides a method for detecting windings at multiple locations in the winding direction of a wound wire, for example, three locations at 1200' intervals, or four locations at 90' intervals (for automation purposes). It may be desirable to have an even number of locations.
), etc., when wrapping a binding hoop made of wire, copper strip, resin band, resin hoop, etc. in a direction perpendicular to the winding direction of the wire rod to form a wire coil, before tightening with the binding hoop. Then, a rocking process is performed to improve the familiarity between the wound adjacent wire rods, and after the rocking process improves the familiarity between the adjacent wire rods, the winding of the wire rods is performed. It is characterized by having a structure in which the binding hoop is wound in a direction perpendicular to the direction,
This kind of precept is used as a means to solve the conventional problems mentioned above. Further, in an embodiment of the present invention, when the wound wire rod is subjected to the swinging process and then tightened using the binding hoop, the tightening using the binding hoop is performed by vertical binding. is desirable. Furthermore, if necessary, after the binding hoop has been tightened, instructions may be given to perform body binding by tightening a body hoop made of a copper band, a resin band, a resin hoop, etc. in a direction intersecting the binding hoop. It is also desirable. (Function of the invention) In order to improve the shape of the wire coil and prevent the occurrence of loose bundles, in which the bundle loosens during storage or transportation, the height of the wire coil at the stage before tightening with a bundling hoop is improved. When we investigated this, we found that there were trends as illustrated in Figures 2 and 3. That is, when the wound wire coil 31 is placed on the rotating roll 46 of the horizontal wire binding device 41 shown in FIG.
As shown in a), the outer peripheral side of the wire coil 31 is restrained by the rotating roll 46, so the ring-shaped wire rods are aligned, and the height (H) of the wire rod coil 31 is as shown in the horizontal type in FIG. It will be expensive. On the other hand, when the wound wire coil 31 is placed on the rotary table 52 of the vertical wire binding device 51 shown in FIG. Since there is no restraint, the ring-shaped wire can be laid down relatively freely due to its own weight, so the height (H) of the wire coil 31 is higher than that of the horizontal wire as shown in the vertical part (before swinging) in Fig. 2. It is considerably lower than when it is placed on the rotating roll 46 of the binding device 41. Furthermore, when the wire rod coil 31 is placed on the rotary table 52 of the vertical wire rod binding device 51 and subjected to the rocking process, the ring-shaped wire rods become sufficiently familiar with each other, as shown in FIG. 3(C).
As shown in Fig. 2, other wires tend to enter the gaps between the wires, and the height (H) of the wire coil 31 becomes even lower as shown in the vertical shape (after swinging) in Fig. 2. . In this case, unlike pressing the wire coil 31 as it is with the movable anvil 44 or the compression plate 58 shown in FIG. Therefore, if you tie the wire with a binding hoop in this condition, it will be possible to bundle the wire in a dense state, making it easier to store. This makes it difficult for the bundle to come loose during shipping or transportation. Further, if necessary, by performing Ir one-turn binding in which the body hoop is wound in a direction intersecting the binding hoop, a wire rod coil that is more secure and less prone to bundle looseness can be obtained. (Example) Next, an example of the present invention will be described with reference to FIGS. 1 and 6. Approximately 13 in outer diameter by winding wire 2 with a diameter of 5.5 mm many times
A wire rod coil 1 having a diameter of 0.00 mm and an inner diameter of approximately 1000 mm is placed on a rotary table 59 of a vertical wire binding device 51 shown in FIG.
The rotary table 5 is rotated by activating a swing drive source (not shown).
At the same time as 9 was oscillated, a oscillating motion was applied to wire coil 1. The rocking motion at this time is 450 to 1200 cycles/
It was about a minute. Next, the rod 53a of the hydraulic cylinder 53 is lowered to bring the compression plate 58 into contact with the upper part of the wire coil 1, and the wire coil 1 is compressed between the rotating table 59 and the compression plate 58 to form a band shape. The iron bundling hoops 3a, 3b, 3c, and 3d made of high-tensile steel strips with a width of 32 mm are wound and tightened. 1 wire coil 1. Then, for some parts, a width of 1
A trunk hoop 4 in the shape of a 9 mm band and made of resin (made of polyester in this embodiment) which is softer than iron is placed in the direction of the winding edge of the wire rod 2, and also attached to the binding hoops 3a to 3a.

Example No. 1 in which the wire rod coil 1 of No. 1 and the body hoop 4 were wound in addition to the iron binding hoops 3a to 3d. 2 wire rod coils 1 and iron binding hoops 33a~ using the vertical binding device 51 without performing rocking process.
Comparative example No. 33d was tightened. 1 wire coil 3
1 and Comparative Example No. 1 in which the iron binding hoops 33a to 33d were tightened using the horizontal wire binding device 41 without performing the swinging process. 2 wire rod coils 31, each wire rod coil 1
．． We repeated the bundle loose drop test in which the wire coils 1 and 31 were lifted to a height of 1 m and then dropped, and the number of falls at which the wire coils 1 and 31 became bundle loose and could no longer stand on their own was investigated, and the results are shown in Table 1. Ta. As shown in Table 1, Comparative Example No. For the wire coil 31 of No. 1, about 15 to 22 times, and for Comparative Example No. In the case of the wire coil 31 of Example No. 2, the bundle became loose after about 10 to 15 turns and could not stand on its own.
o. In the case of the wire rod 1 of Example 1, the bundle becomes loose after about 28 to 36 turns, and in the case of the wire coil 1 of Example 2, it becomes impossible to stand on its own after about 38 to 45 times, and the bundling is better than that of the conventional case. It was possible.

【Effect of the invention】

In this invention, at multiple locations in the winding direction of the wound wire,
When winding a binding hoop in a direction perpendicular to the winding direction of the wire rod to form a wire rod coil, the wound adjacent wire rods are made to fit well with each other before winding with the binding hoop. The structure is such that the oscillation process is performed, and after the oscillation process makes the adjoining wire rods fit together well, the binding hoop is tightened in a direction perpendicular to the winding direction of the wire rods. When binding wire rods wound in a shape, wire coils can be bundled sufficiently well while preventing the occurrence of scratches due to the pressure of the wire phase buds. Bundle looseness, where the bundle becomes loose, is less likely to occur, and the problem of irregularities in the outer diameter of the wire rod coil is suppressed, so the stacked inventory and transportation of wire rod coils can be carried out smoothly, and the wire rod surface does not have wire coils on the surface of the wire rod during transportation. This makes it difficult for scratches to form due to poor shape, reducing the need for grinding due to scratches.Furthermore, since the shape of the wire coil is not easily disturbed, it can be pickled or annealed as is. As a result, roughness and tangles of the wire are less likely to occur, resulting in significant effects such as improved workability during wire drawing.
