2. Description of the Related Art In the production of metal wire products such as steel cords, particularly bead wires for tires, atmosphere gas,
2. Description of the Related Art It has been widely practiced to continuously pass a metal wire rod through a plurality of processing means containing a fluid such as a plating solution and a cleaning solution, and continuously perform a heat treatment, a plating process, a cleaning process, a drying process, and the like. In this continuous processing, in order to cause the metal wire to travel on a predetermined pass line, the wire is often guided by a free-rotating roller that is rotated by the traveling wire.

For example, in a process in which a metal wire is immersed in a liquid, such as plating, pickling, etc., conventionally, as shown in FIG. 52, between which rollers 5
By providing 3 and 54, the wire 21 has been introduced into the liquid. However, there is a problem that the rollers 53 and 54 provided in the liquid cause rotation failure and damage the traveling metal wire 21, and a method of treating the wire while overflowing the liquid in the tank is adopted.

FIG. 7 shows an example of an apparatus for electroplating a metal wire 21 while overflowing a plating solution in a tank. The electroplating apparatus 60 shown in FIG. 7 has a processing tank 61 provided with an anode at the bottom and an auxiliary tank 62, and supplies a plating solution from the auxiliary tank 62 to the processing tank 61 by a pump P. The metal wire 21 can be immersed in the plating solution without providing a roller in the solution according to such an apparatus. Further, three rollers 63, 64, and 65 are provided at the entrance and the exit of the plating tank, respectively. The metal wire 21 supported by the rollers 63 and 65 is pressed by the roller 64 so that the metal wire 21 and the roller To ensure contact
The power supply by the roller 64 is stabilized.

[0005] In electroplating a metal wire,
In order to make the plating current density uniform, it is often the case that the plating tank is divided into a plurality of tanks, and power is supplied by rollers provided between the tanks. FIG. 8 is an example of an apparatus that performs electroplating on the metal wire 21 by sequentially passing through a plurality of processing tanks 61 using the electroplating apparatus 60 illustrated in FIG. 7 as an element. In the processing using such an apparatus, a space for providing at least three (63, 64, 65) rollers between each processing tank is required, so that there is a problem that productivity per apparatus length is low. . Further, since the metal wire 21 is bent at least three times between the tanks, there is a problem that mechanical properties such as straightness and strength of the treated metal wire 21 are impaired.

[0006] In particular, the problem of adverse effects on straightness and mechanical properties of a metal wire due to processing is particularly important in a final process line for commercializing a metal wire, such as production of a bead wire for a tire. Have been tried.

For example, JP-A-6-2049 discloses that
Using a device as shown in FIG. 9 in which the wire contact position of each roller is substantially straight, the drawn metal wire 21 fed from the pay-out reel 71 is passed through a substantially straight pass line in a fluidized bed furnace 72. A method for manufacturing a bead wire that is heated and then subjected to a series of plating processes in a plating tank 70 is disclosed. Such a plating tank 70 includes a pickling tank 73,
The wire rod 21, which includes a washing tank 74, a copper plating tank 75, a washing tank 76, and a hot water washing tank 77, and has been subjected to the plating process, is taken up on a take-up reel 78. However, according to the method disclosed in this publication, even if there is a slight variation in the installation height or the roller diameter of the rollers 79 to 89, some of the rollers do not rotate, and rub against the traveling wire to damage the wire. There is a problem. Further, since the contact pressure between the rollers 79 to 89 and the wire 21 is low and the contact state is unstable, it is not suitable for continuous processing including electroplating or the like which requires power supply to the wire by the rollers.

[0008] A method for manufacturing a bead wire including electroplating on a metal wire is also disclosed in Japanese Patent Application Laid-Open Nos. 2-175884 and 3-8880. Does not disclose anything about the roller installation method and the wire rod pass line.

[0009]

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a method and an apparatus for continuous treatment of a metal wire according to the present invention will be described with reference to FIG. 1 by taking brass plating treatment on a steel wire as an example. The plating processing line shown in FIG. 1 includes an unwinding means (not shown), a degreasing tank 1, a washing tank 2, an pickling tank 3, a washing tank 4, and a copper electroplating tank 5.
a to 5c, washing tank 6, zinc electroplating tank 7, hot water tank 8,
This is an example in which an electric heating device 9 and a winding means (not shown) are arranged in series, and the present invention is applied to a portion from an inlet of the degreasing tank 1 to an outlet of the hot water washing tank 8.

That is, the degreasing tank 1, the washing tank 2, the pickling tank 3, the washing tank 4, the copper electroplating tanks 5a to 5c, the washing tank 6,
Each of the zinc electroplating tank 7 and the hot water washing tank 8 is a unit processing means, and these unit processing means are arranged in series in the running direction of the wire to form a wire continuous processing section 20. In addition, one roller 11 and one roller 12 are provided at the entrance and exit of the continuous wire rod processing unit 20, that is, at the entrance of the degreasing tank 1 and the exit of the hot water washing tank 8, respectively. Here, the roller 12 at the outlet of the hot water washing tank 8 also functions as a power supply roller of the electric heating device 9.
Further, among the positions (nine locations in FIG. 1) sandwiched between adjacent unit processing means in the wire rod continuous processing unit 20, between each unit processing means from the washing tank 4 to the hot water washing tank 8 (6 in FIG. 1).
) Are provided with rollers 13 to 18 respectively.

The metal wire 21 traveling between the inlet roller 11 and the outlet roller 12 of the continuous wire processing section 20 sequentially contacts and passes through the rollers 13 to 18 to form a wire pass line. The position where the roller is in contact with the wire from the inlet roller 11 to the outlet roller 12 of the wire rod continuous processing section 20 is designed not to be located on the same side continuously more than three times with respect to the rotation axis of the roller. . The positions where the rollers and the wire contact each other in the plating process line shown in FIG. 1 are as shown in Table 1 below.

[0020]

[Table 1]

Here, the contact between each roller and the wire 21 is
The reason for avoiding the same side continuously for more than three times with respect to the rotation axis of the roller is that the contact between the wire and the roller is ensured and each roller is rotated reliably, and the contact pressure and contact between the wire and the roller This is because the area can be adjusted.
For example, as shown in FIG. 10, when the position where the wire 21 contacts the roller is set to the same side continuously three times or more with respect to the rotation axis of the roller, the rollers 66 to 68 support the wire 21 from the same direction. Therefore, the contact pressure between each roller and the wire is small, and even if the tension of the wire is increased, the contact pressure between the roller and the wire cannot be increased. Further, if the wire contact position of the rollers 66 to 68 deviates from a straight line due to a variation in the installation height of the rollers, abrasion of the rollers, or the like, the contact pressure between some of the rollers and the wires is significantly reduced, and the wires travel. In this case, the roller does not rotate. Then, there arises a problem that the non-rotating roller and the wire rub against each other to damage the wire.

On the other hand, in accordance with the present invention, as shown in FIG. 1, the position where each roller and the wire 21 contact each other is prevented from being on the same side more than three times with respect to the rotation axis of the roller. In this case, at least the rollers immediately upstream or immediately downstream of each of the rollers located between the inlet roller 11 and the outlet roller 12 support the wire in a direction in which the wire is pressed against the roller. The contact with the rollers is reliably maintained, and each roller can be reliably rotated. Further, by adjusting the tension of the traveling wire, the contact pressure between the wire and the roller can be adjusted. Further, the contact pressure of the wire with respect to the rotation axis of the roller is different from each other, and the contact pressure and the contact length between the wire and the roller can be adjusted by adjusting the difference in the height of the wire contact position between adjacent rollers. . For this reason, in the present invention, a continuous electroplating line for a metal wire rod including a roller that also functions as a wire rod guide and power supply, such as the rollers 13 to 16, the roller 17, the roller 18, and the roller 12 in FIG. It is suitable.

It is sufficient that the number of rollers provided between the unit plating tanks is one. Further, for example, as shown in FIGS. 3 and 4 of the following embodiment, in the case of electroless plating or the like that does not require power supply by a roller, the roller does not exist continuously between the unit plating tanks in the continuous plating process. May be. As a result, it is possible to achieve a reduction in the length of the line including the wire rod continuous processing section 20 and a reduction in the number of times the wire is bent during the processing.

Further, by setting the diameter of each roller to be 50 times or more the diameter of the wire to be processed, the influence of the bending by the roller on the straightness of the wire can be suppressed to an almost negligible level.

Furthermore, when a facility including a roller is provided upstream or downstream of the continuous wire processing section 20 to perform continuous processing, at least the inlet roller 11 of the continuous wire processing section 20 is used.
The position where the running wire rod contacts the roller, including the roller immediately upstream of the roller or the roller immediately downstream of the outlet roller 12, should not be on the same side more than three times continuously with respect to the rotation axis of the roller. preferable. Thereby, the entrance roller 1
1 and the contact state of the wire at the outlet roller 12 can be improved.

By the way, in order to match the pass line of the wire rod continuous processing section 20 with the pass line of the equipment provided upstream or downstream thereof, for example, as shown in FIG. If the fluidized bed furnace 30 having the wire path line is provided upstream of the continuous wire processing section 20, the position where the running wire 21 contacts the rollers is the roller 31, the roller 32, and the entrance roller 11 of the continuous wire processing section 20. In some cases, the roller 13 must be on the same side with respect to the rotation axis of the roller continuously three times or more.
In this case, the inlet roller 11 of the wire rod continuous processing unit 20
In addition, the contact of the wire 21 with the roller 32 of the fluidized bed tends to be uncertain. In such a case, as shown in FIG. 2B, one more roller 22 is provided immediately upstream of the inlet roller 11 of the wire rod continuous processing section 20 and the rollers 31 and 32 of the fluidized bed furnace 30 are included. The desired effect of the present invention can be sufficiently exhibited by preventing the position where the traveling wire rod 21 comes into contact with the roller from being on the same side more than three times continuously with respect to the rotation axis of the roller. Can be The same applies to a case where a facility including a roller is provided downstream of the wire rod continuous processing section 20 to perform continuous processing.

On the other hand, in each unit processing means, a wire rod pass line is formed so that the wire passes straight through the fluid contained therein. The wire rod continuous processing unit 20 shown in FIG.
When the wire passes through the liquid as in each of the unit processing means 1 to 8, the rollers on both sides of the unit processing means make the wire rod pass line straight, and the liquid overflows so that the liquid surface is higher than the wire pass line. It can be implemented by raising. When the wire is passed through a gas such as an atmosphere gas or a high-temperature gas, a gas storage chamber surrounding a wire pass line linearized by rollers on both sides of the unit processing means is provided, and gas is purged or circulated therein. Can be implemented.

The copper electroplating tanks 5a to 5a shown in FIG.
5c, when the wire pass line passing through the overflowing liquid in the unit processing means is not horizontal, such as the washing tank 6 and the hot water tank 8, the height of the tank wall on the lower side of the wire pass line is changed to the opposite side. It is preferable that the height is equal to or higher than the height of the tank wall, and a slit through which the wire passes is provided in the tank wall so that the wire pass line is not exposed outside the liquid over the entire length of the unit processing means.

The above-described method and apparatus for continuously treating a metal wire according to the present invention are particularly suitable for a final process line for commercializing a metal wire in the production of bead wires for tires and the like.

An embodiment in which the present invention is applied to manufacture of a bead wire is as follows. That is, unwinding means, winding means, heat treatment means, water washing tank, pickling tank,
Forming a bead wire production line having a plating processing section including a plurality of unit processing means containing a fluid, such as a plating tank and a drying furnace, and at least configuring the plating processing section to the above-described wire rod continuous processing according to the present invention. The diameter of each roller is at least 50 times the diameter of the metal wire. The heat treatment means is preferably a fluidized bed furnace in which rollers having a diameter of at least 50 times the diameter of the metal wire to be treated are provided at the inlet and the outlet and the pass line is straightened. And the position where the traveling wire rod contacts the rollers, including the rollers at the inlet and outlet of the fluidized bed furnace, is continuously on the same side at least three times with respect to the rotation axis of the rollers. It is preferable to use a wire rod pass line. Further, it is preferable to minimize the number of places where the rollers are installed and to reduce the number of times the wire is bent by the rollers as much as possible.

[0031]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail based on an embodiment applied to a final process line in bead wire manufacturing. Example 1 As shown in FIG. 3, unwinding means (not shown), fluidized bed furnace 30, plating section 40 and winding means (not shown)
Were arranged in series to form a bead wire production line for processing a plurality of high carbon steel wires having a diameter of 0.96 mm by running in parallel. The plating section 40 was configured by arranging a water cooling tank 41, an acid washing tank 42, a water washing tank 43, an electroless bronze plating tank 44, a hot water washing tank 45, and a drying furnace 46 in series.
Rollers 11 are provided at the entrance and exit of the plating section 40.
And 12 were provided. In addition, only one roller installation point in the middle of the plating section 40 was provided between the hot water washing tank 45 and the drying furnace 46, and one roller 13 was provided here. Each roller is a cylindrical roller having a diameter of about 80 mm, and each of the rollers 11, 13 and 12 guides a plurality of high carbon steel wires running in parallel. The fluidized bed furnace 30 has grooved rollers 31 and 32 having a diameter of about 100 mm at its inlet and outlet, and forms a straight wire pass line by bringing the wire into contact with the lower portion of these rollers. is there.

A high-carbon steel wire wound to a diameter of 0.96 mm by wire drawing was set on an unwinding means, and successively contacted with rollers to form a wire pass line leading to the winding means. As shown in FIG. 3, the position where the traveling wire 21 contacts the rollers, including the rollers 31 and 32 at the inlet and outlet of the fluidized bed furnace 30, is set with respect to the rotation axis of the rollers. This is a wire rod pass line that is not on the same side three or more times consecutively.

The part between the roller 11 and the roller 13 in the wire rod pass line is made horizontal,
The liquid in each tank from to the hot water washing tank 45 overflowed, and the liquid level in each tank was positioned above the wire rod pass line. When unit processing means for liquid immersion processing that does not require power supply by a roller or the like is continuous as in this embodiment, unit processing is performed by forming a wire rod pass line in this series of unit processing means horizontally. Processing can be performed smoothly without providing rollers between the means.

In this case, in order to prevent entanglement between adjacent wires when the wire 21 is broken, means for isolating adjacent and parallel wires may be provided in the middle of a series of unit processing means. Good. In the embodiment shown in FIG. 2, an isolation means 47 as shown in FIG. The isolating means 47 includes a lower member 48 fixed to the outlet of the washing tank 43 and a removable upper member 49. The upper member 49 can be removed at the time of wiring work or the like. The separating means 47 does not come into contact with the wire when the wire is traveling normally, and is not involved in the formation of the wire pass line.

The drying oven 46 is provided along the straight wire path line between the rollers 13 and 12 and slightly inclined.

When a bronze-plated bead wire having a diameter of 0.96 mm was manufactured on the above-described bead wire manufacturing line, each roller smoothly rotated to guide the wire rod,
There was no damage to the wire. The straightness of the manufactured bead wire was also good.

Embodiment 2 As shown in FIG. 4, unwinding means (not shown), fluidized bed furnace 30, plating section 40 and winding means (not shown)
Were arranged in series to form a bead wire production line for processing a plurality of high carbon steel wires having a diameter of 0.96 mm by running in parallel. The configuration of the plating section 40 in the bead wire production line shown in FIG. 4 is the same as that of the above-described first embodiment, including the wire rod pass line.
Is of a type different from that of the first embodiment. That is, the fluidized bed furnace 30 shown in FIG. 4 has grooved rollers 31 and 32 having a diameter of about 100 mm at the inlet and the outlet similarly to the fluidized-bed furnace of the first embodiment.
The linear material pass line is formed by bringing the wire into contact with the upper part of these rollers. Therefore, the roller 22 is added just upstream of the inlet roller 11 of the plating section 40, and the rollers including the rollers 31 and 32 at the inlet and outlet of the fluidized bed 30 and the added roller 22 travel as shown in FIG. A wire pass line was formed in which the position where the wire was in contact with the roller was not on the same side continuously three times or more with respect to the rotation axis of the roller. In addition, the added roller 22 can be moved up and down so as not to deteriorate the workability of the line.

In this bead wire manufacturing line, the diameter of the bead wire is set to 0.
When a 96 mm bronze-plated bead wire was manufactured, as in Example 1, each roller smoothly rotated to guide the wire, and the wire was not damaged. The straightness of the manufactured bead wire was also good.

Comparative Example For comparison, as shown in FIG. 11, the roller 22 added in Example 2 was removed, and
When the installation position of the drying furnace 46 was changed and a bronze-plated bead wire having a diameter of 0.96 mm was manufactured on a manufacturing line in which the pass line from the roller 31 to the roller 12 was straightened, the rollers 32, 11 and 12 smoothly rotated. Rubbed with the wire rod without causing any damage to the manufactured bead wire.

[0040]

As described above, by applying the method and apparatus for continuous processing of a metal wire according to the present invention, the metal wire is accommodated in a plurality of unit processing means while running while being guided by rollers. In continuous processing of metal wires, which are subjected to heat treatment, plating, cleaning, drying, etc. by successively passing through a fluid, the space required for roller installation is reduced, the wire and the rollers are reliably and stably contacted, and the rollers are In this way, it is possible to suppress the adverse effects such as damage and deformation of the wire rod caused by processing while guiding.
