DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a wire tube and a device for winding a wire tube, and more particularly to a method for winding a long wire tube continuously produced as an intermediate product of an inner grooved heat transfer tube into a receiving basket. The present invention relates to a winding method of a wire tube material that can be more advantageously wound in a loop shape, and a winding device of a wire tube material that can be suitably used when performing such a method.

[0002]

2. Description of the Related Art Conventionally, as one type of heat transfer tube for a heat exchanger such as an evaporator or a condenser in a refrigerator or an air conditioner, a so-called inner grooved heat transfer tube in which a predetermined groove is formed on a tube inner surface. Although it is used, this inner grooved heat transfer tube is generally
First, a continuous elongate raw tube is continuously subjected to a drawing process with a diameter reduction using a processing machine such as a rolling machine or a drawing machine to obtain a wire tube material. It is manufactured by cutting the wire tube into a desired length while forming a predetermined groove on the inner surface of the wire tube by a process.

[0003] As is well known, a wire tube material, which is an intermediate product of such a heat transfer tube with an inner surface groove, is usually made of
It will be produced with an extremely long length, with a total length of 6,000 to 10,000 m. For this reason, conventionally, a wire tube continuously supplied from a processing machine such as a rolling machine or a drawing machine is put into a bottomed cylindrical receiving basket rotating around an axis, and wound. Once wound into the receiving basket so as to form a large number of loops made of the wire tube,
It is stored and then unwound at a high speed and used at another processing site or the like so as to form a straight pipe extending straight in the axial direction from within the receiving basket.

As described above, when a long wire tube continuously supplied is wound into a receiving basket, a large number of loops formed by the wound wire tube are randomly arranged with large positional variations in the radial direction. When the wire tube is wound, the efficiency of storing the wire tube material in the receiving basket is deteriorated. And then,
While storing all of the produced wire tube in the receiving basket, it is necessary to replace the receiving basket filled with wire tube material with another empty receiving basket many times, which requires a lot of work. In addition to this, when exchanging the receiving basket, the production process of the wire tube must be stopped, so that the production efficiency of the wire tube is remarkably reduced.

In addition, if the wire tube is randomly wound into the receiving basket, when the wire tube is rewound from the receiving basket at a high speed, the wire tube contacts the inside of the receiving basket due to mutual contact or the like. Scratches and the like occur on the surface of the tube material, which causes a deterioration in the surface quality of the finally obtained heat transfer tube with an inner surface groove. Even the production efficiency of heat transfer tubes can be very negatively affected.

Therefore, conventionally, when winding a wire tube into a receiving basket, for example, an operator visually checks the winding state (storage state) of the wire tube material into the receiving basket, while viewing the receiving basket. By manually changing the rotational speed of the wire tube and adjusting the feeding position of the wire tube, a method of orderly winding the wire tube into the receiving basket, and softwareizing such manual operation by the operator, this software Based on the above, a method of automatically controlling the rotation speed of the receiving basket according to the winding state of the wire tube material or the like is adopted.

However, in each of these conventional methods of winding a wire tube, the internal space of the receiving basket is divided into a plurality of radially adjacent regions, and the inside of the radially outermost region is divided into a plurality of regions. After winding the wire tube at a time to the desired height position of the receiving basket, in the same manner, in the area inside, sequentially,
Since the wire tube is wound, for example, when the wire tube is wound into a region located outside in the radial direction, when the height of the wound wire tube gradually increases, such a wire tube material is used. Some of the loops composed of may collapse or protrude toward the inner side of the outer region, and in such a case, the loop formed of the wire tube material wound into the outer region And the loop made of the wire tube wound into the inner region, which makes it difficult to orderly store the wire tube material in the receiving basket.

Therefore, according to the conventional winding method of a wire tube, which simply divides the inside of the receiving basket into a plurality of regions in the radial direction and winds the wire tube sequentially from the outside thereof, the inside of the receiving basket of the wire tube material may be changed. It was impossible to achieve a stable and sufficient improvement of the storage efficiency in the storage.

[0009]

Here, the present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to arrange a continuously supplied wire tube in a receiving basket in a more orderly manner. It is an object of the present invention to provide a method of winding a wire tube, which can be wound in and can stably and sufficiently improve the efficiency of storing the wire tube in a receiving basket. Another object of the present invention is to provide a winding device for a wire tube, which can improve the efficiency of storing the wire tube in a receiving basket.

[0010]

According to the present invention, in order to solve such a problem, a continuously supplied wire tube is charged into a bottomed cylindrical receiving basket rotating around an axis. In the method of winding the wire tube, the loop made of the wire tube wound into the receiving basket so that a plurality of loops made of the wire tube are formed in the receiving basket by being wound. A plurality of small blocks including those having different average diameters of the plurality of loops, and among the plurality of small blocks, the smaller the average diameter of the plurality of loops is, The plurality of small blocks are arranged in a required number in the radial direction of the receiving basket so as to be located radially inward of the receiving basket. , The winding insertion method of lines tubing, characterized in that the sequentially stacked in a height direction of the les sieving basket, is to its gist.

In short, the method for winding a wire tube according to the present invention requires a small block composed of a plurality of loops of the wire tube as a first step on the bottom surface of the receiving basket. After arranging by the number in the radial direction of the receiving basket, the second stage small block is arranged in the same arrangement form as the first stage on the first stage small block arranged on the bottom surface of the receiving basket. It is arranged, and if necessary, the small blocks of one or more stages are sequentially stacked on the small blocks of the second stage in the same arrangement form as the small blocks of the first and second stages. Thereby, the wire tube is wound into a predetermined position in the receiving basket to a desired height.

That is, according to the method of the present invention, the inside of the receiving basket is divided into a plurality of regions in the radial direction, and the wire tube material is simultaneously moved to a desired height in the region located on the outer side in the radial direction. After being wound in the same way, in the same manner, the conventional method of sequentially winding the wire tube material into the inner area, in other words, from a relatively large amount of wire tube material wound into the receiving basket. The conventional method of forming a tall block composed of a large number of loops, while simply arranging them at a predetermined position in the receiving basket while arranging them in the radial direction of the receiving basket, includes: The arrangement of the block of the wire tube formed in the receiving basket in the receiving basket is greatly different. Every single size of the block, as compared with the case of employing the conventional method, it was obtained without sufficiently small.

Therefore, according to the method of the present invention, the small blocks of the wire tube material are placed at a predetermined position in the radial direction of the receiving basket or when they are stacked in the height direction. It has become possible to advantageously prevent some of the loops made of the constituting wire tube material from protruding or collapsing to a position other than the predetermined position due to the height of the small block being too high. It is.

Therefore, according to the method for winding a wire tube according to the present invention as described above, a continuously supplied wire tube can be wound in a receiving basket in a more orderly and stable manner. It is possible to sufficiently improve the efficiency of storing the wire tube material in the inside. As a result, the number of replacements of the receiving basket accompanying the stoppage of the production process of the wire tube can be reduced as much as possible, and the production efficiency of the wire tube can be increased extremely effectively.

Moreover, in the method for winding a wire tube according to the present invention, since the continuously supplied wire tube can be wound more neatly and stably into the receiving basket, the wire tube can be wound from the receiving basket. When rewinding at a high speed, it is possible to effectively prevent abrasion or the like from being generated on the surface of the wire tube material or to cut the wire tube material, and thereby, a final product produced from the wire tube material Both the quality and the production efficiency can be advantageously achieved.

According to one advantageous aspect of the present invention, the receiving basket has a bottom having an outer tubular wall and an inner tubular wall standing coaxially with respect to a bottom. The plurality of small blocks arranged in the radial direction of the receiving basket are configured to have a cylindrical shape, and the small block having the largest average diameter of the plurality of loops is changed to the outer cylinder of the receiving basket. The small block having the smallest average diameter of the plurality of loops is positioned radially outwardly from the inner cylindrical wall of the receiving basket while being positioned in contact with the wall. .

In the method of the present invention, the small block having the largest average diameter of the plurality of loops is arranged so as to be brought into contact with the outer cylindrical wall of the receiving basket. The outermost small block in the direction can be positioned with high accuracy along the outer cylindrical wall in the height direction, and the collapse of the loop of the wire tube material constituting those small blocks, The small blocks located inside the outermost small blocks in the radial direction of the receiving basket can also be well blocked by the outer cylinder wall, and the small blocks located outside the outer basket walls can be well blocked. With the block, high-precision positioning and prevention of loop collapse can be realized effectively, and as a result, Winding in of the sieving basket is than so that the more may further orderly performed.

In the method of the present invention, the small blocks having the smallest average diameter of the plurality of loops are arranged radially apart from the inner cylindrical wall of the receiving basket. The variation in the diameter of the loop between the wire tube constituting the small block having the smallest average diameter of the plurality of loops and the wire tube constituting the small block having the largest average diameter can be made as small as possible.

Therefore, if the method of the present invention is adopted, when the wire tube is rewound from the receiving basket at a high speed, the diameter of the loop of the wire tube wound into the receiving basket may vary.

<1/5. Thereby, the average diameter of the plurality of loops and the variation of the diameter of the loop of the wire tube constituting the small block having the largest average diameter and the diameter of the loop of the wire tube constituting the small block having the smallest average diameter can be reduced more effectively. Accordingly, the adjustment of the unwinding speed when the wire tube is unwound from the receiving basket at a high speed can be advantageously simplified, and the productivity of the product processed from the wire tube can be further improved. You get it.

According to still another preferred aspect of the present invention, a difference between a maximum diameter and a minimum diameter of the plurality of loops constituting each of the plurality of small blocks: n;

However, the wire tube is wound into the receiving basket while forming the plurality of small blocks so that 1/15 <n / d <1/10. In the method of the present invention having such a configuration, the size of each small block can be reliably reduced in size, whereby the turbulence of the wire tube constituting the small block is more advantageously reduced. It can be suppressed and the winding of the wire tube into the receiving basket can be carried out even more orderly.

Still further, according to another advantageous aspect of the present invention, a position where the wire tube is inserted into the receiving basket in a radial direction of the receiving basket is detected, and the detected wire tube is detected. The rotation speed of the receiving basket is increased or decreased so that the input position of the receiving basket coincides with the target position changed according to the winding length of the wire tube wound into the receiving basket. While controlling the feeding position of the wire tube in the radial direction, the wire tube is put into the receiving basket and wound to form a plurality of loops made of the wire tube wound into the receiving basket. The small block composed of
While a plurality of loops are formed including those having different average diameters of the plurality of loops according to the input position of the wire tube, the input position of the wire tube among the plurality of small blocks is in the radial direction of the receiving basket. The plurality of small blocks are positioned inward in the radial direction of the receiving basket so that the smaller the average diameter of the plurality of loops is, the smaller the average diameter of the plurality of loops is. The receiving baskets are sequentially stacked in the height direction of the receiving basket while arranging the necessary number of the receiving baskets.

According to such a method of the present invention, the winding of the continuously supplied wire tube into the receiving basket can be performed not only in a more orderly and stable manner, but also by such automatic winding operation. Labor saving can be advantageously achieved, whereby the production efficiency and / or productivity of the wire tube can be improved even more effectively.

Further, in the present invention, in order to solve the problem relating to the method for winding the wire tube material, the wire tube material is continuously supplied into a bottomed cylindrical receiving basket rotating around an axis.

A charging position of the wire tube into the receiving basket is detected, and the detected charging position of the wire tube is
By increasing or decreasing the rotation speed of the receiving basket so as to coincide with a predetermined target position, while controlling the input position of the wire tube in the radial direction of the receiving basket, the wire tube is inserted into the receiving basket. A method for winding a wire tube, which is characterized in that it is inserted, is also the gist of the invention.

In the winding method of the wire tube according to the present invention, the wire tube can be more reliably wound into the receiving basket at the target charging position, whereby the wire tube can be received by the receiving basket.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, in order to clarify the present invention more specifically, the structure of a wire tube material winding device and a wire tube material winding method according to the present invention will be described with reference to the drawings.
It will be described in detail.

First, FIG. 1 schematically shows an example of a wire tube winding device having a structure according to the present invention, which can advantageously implement the wire tube winding method according to the present invention, including a block diagram. Is shown. In FIG. 1, 10
Is a receiving basket, which has a cylindrical shape with a bottom that opens upward as a whole. Further, in the receiving basket 10, the outer cylindrical wall portion 12 and the inner cylindrical wall portion 14 having the same height are provided at predetermined intervals in the radial direction at the outer peripheral edge portion and the inner peripheral portion of the bottom portion. The inner space between the inner peripheral surface of the outer cylindrical wall portion 12 and the outer peripheral surface of the inner cylindrical wall portion 14 is
It is a storage space in which the wire tube 16 is stored. In addition,
The wire tube material 16 housed in the receiving basket 10 is formed by rolling a single long metal tube with a known rolling machine (not shown) to form an intermediate processed product of a heat transfer tube with an inner surface groove. Is produced with an extremely long length of about 10,000 m and is continuously supplied from a rolling machine.

A receiving motor 18 is arranged below the receiving basket 10. A driving shaft (not shown) of the receiving motor 18 is connected to the receiving basket 10 via a well-known speed reducer 20. 10 is connected to the bottom part so as to be integrally rotatable. Thereby, the receiving basket 10 is rotated around the axis with the rotation of the receiving motor 18.

On the other hand, the receiving basket 10
A guide table 2 which has a rectangular plate shape and guides the wire tube material 16 in the longitudinal direction right above the outer cylindrical wall portion 12 of the guide tube 2.
2 are arranged. Also, the guide table 22
A guide roller 24 for feeding the wire tube 16 guided by the guide table 22 into the receiving basket 10 is attached to one end in the length direction. Then, the guide table 22 is inclined downward at a relatively gentle angle so that the mounting end of the guide roller 24 is located on the lower side, and the extension line of the center line extending in the length direction is the outer line. In a state where it is positioned so as to extend along the inner peripheral surface of the cylindrical wall portion 12, it is fixed to a position fixing member (not shown) different from the receiving basket 10.

Thus, the wire tube 16 continuously supplied from a rolling machine (not shown) is sent out by the guide rollers 24 while being guided by the guide table 22, and is rotated in the receiving basket 10 by the receiving motor 18. It is to be thrown into.
Then, as shown in FIG. 2, the wire tube 16 put into the receiving basket 10 is wound with the rotation of the receiving basket 10, so that the wire tube material put into the receiving basket 10 is turned on. It is wound and stored so that a large number of loops 25 consisting of 16 are formed.

As shown in FIGS. 1 and 2, the winding device of the present embodiment has a receiving basket 1
A material position detecting sensor 26 as a detecting means for detecting a position at which the wire tube material 16 is inserted into the inside of the receiving tube 10, and the wire tube material 16 into the receiving basket 10 based on the detected position detected by the material position detecting sensor 26. A controller 28 is provided as a control means for controlling the input position of the device.

That is, the material position detecting sensor 26 is disposed horizontally toward the center axis of the receiving basket 10 near the guide table 22 provided above the outer cylindrical wall portion 12 of the receiving basket 10. The wire tube 16 guided by the guide table 22 and sent out from the guide roller 24 receives the material position detection sensor 26 and the receiving basket 10.
Passing through the center axis of the receiving basket 1
It is positioned so that it is thrown into zero. In the material position detection sensor 26, the distance from the sensor 26 to the wire tube 16 at the injection position into the receiving basket 10 is measured by a conventionally known structure. Based on this, the position where the wire tube 16 is inserted into the receiving basket 10 in the radial direction of the receiving basket 10 can be detected.

On the other hand, the controller 28 has a basic configuration as shown by a block diagram in FIG. 1, and the feeding position of the wire tube 16 detected by the material position detecting sensor 26 is wound around the receiving basket 10. The receiving basket 1 is adjusted so as to coincide with a target position which is variously changed according to the winding length of the inserted wire tube 16.
By increasing or decreasing the rotation speed of 0, the feeding position of the wire tube 16 into the receiving basket 10 in the radial direction of the receiving basket 10 can be controlled.

More specifically, the controller 28 includes a changing unit 30, first to fourth compensating units 32 to 38, and an operating unit 40. Of the components of the controller 28, the changing unit 30 includes the wire tube 1
As a target position of the wire tube 16 determined in accordance with the winding length of the wire 6, the distance between the wire tube 16 and the material position detection sensor 26 at the position where the wire tube 16 is inserted into the receiving basket 10 is determined. Are predetermined and stored in correspondence with the predetermined winding lengths. In addition, the change unit 30 has a feeding length of the wire tube 16 detected by a known detecting device provided in a rolling machine (not shown), and a winding length of the wire tube 16 into the receiving basket 10. As is input. Then, in the change unit 30, the target position is changed in accordance with the input winding length of the wire tube material 16, and the changed target position is transmitted from the change unit 30 to the first to fourth compensating units 32. To 38 are output.

The first compensator 32, the second compensator 34, and the third compensator 36 of the four compensators 32 to 38 to which the target position is input are all used when the target position is changed. In order to minimize the amount of overshoot of the input position of the wire tube 16 as a control amount, predetermined compensation (correction) is performed on the target position input to each of the compensating units 32-36. Is configured.

That is, in the first compensator 32, the delay of the step response of the receiving motor 18 caused when the rotation speed of the receiving motor 18 is increased or decreased by changing the target position is determined based on the characteristics of the receiving motor 18. Is corrected (compensated) for the input target position.

The second compensator 34 compensates for the dead time that occurs when the insertion position of the wire tube 16 is changed in accordance with the change of the target position, while the third compensator 36 changes the target position. The feeding speed of the wire tube 16 from a rolling machine (not shown) and the receiving basket 10
This compensates for the fluctuation (run-out) in the radial direction of the receiving basket 10 of the input position of the wire tube material 16 caused by the difference between the winding speed of the wire tube material 16 and the winding speed due to the rotation of. These second and third compensation units 3
Compensation for the target position in the steps 4 and 36 is performed based on an arithmetic expression or the like obtained by various experiments performed in advance.

In the fourth compensating section 38, the first compensating section 3
Proportional / integral compensation is performed on the deviation between the target position output from 2 and the insertion position of the wire tube 16 detected by the material position detection sensor 26.

On the other hand, in the operating section 40, the first to fourth compensating sections 32 are changed according to the winding length of the wire tube 16 and
The deviation between the target position for which the predetermined compensation has been performed in Steps 38 to 38 and the input position of the wire tube 16 detected by the material position detection sensor 26 is converted into the rotation speed of the receiving motor 18 and the deviation is converted to the deviation. Corresponding receiving motor 18
The rotation speed increase / decrease command is output.

That is, when the target position is changed according to the winding length of the wire tube 16, the distance between the wire tube 16 and the material position detection sensor 26 measured by the material position detection sensor 26 is equal to the target value. In other words, if the insertion position of the wire tube 16 is located inside the receiving basket 10 in the radial direction from the target position, the receiving motor 18 is measured by the material position detection sensor 26. A speed increase command corresponding to the difference between the value and the target value is output. On the other hand, when the measurement distance between the wire tube 16 and the material position detection sensor 26 by the material position detection sensor 26 is smaller than the target value, that is, the input position of the wire tube 16 is smaller than the target position. Also, if the outside of the receiving basket 10 in the radial direction,
The deceleration command corresponding to the difference between the value measured by the material position detection sensor 26 and the target value is output to the receiving motor 18.

The speed reference of the receiving motor 18 is added to the rotation speed increase / decrease command of the receiving motor 18 output from the operation unit 40, and the wire tube 16 detected by the material position detection sensor 26 is added. The rotation speed of the receiving motor 18 for rotating the receiving basket 10 so that the feeding position of the receiving basket 10 coincides with the target position which is variously changed according to the winding length of the wire tube 16 wound in the receiving basket 10. The command is output to the receiving motor 18.

Thus, in the winding device of the present embodiment, the rotation speed of the receiving basket 10 is increased or decreased in accordance with the winding length of the wire tube 16 wound in the receiving basket 10. Thus, the continuously supplied wire tube 16 can be put into the receiving basket 10 at a desired position in the radial direction of the receiving basket 10 according to the winding length.

Next, one embodiment of a method of winding a wire tube into a receiving basket according to the method of the present invention will be described in detail.

In the present embodiment, as shown in FIG. 3, as a method of winding all of the continuously supplied wire tube 16 having a total length of about 4000 m into the receiving basket 10, the wire tube 16 is put into the receiving basket 10. While a total of three small blocks 42 composed of a plurality of the loops 25 made of the wire tube material 16 are formed in two types having different average diameters of the plurality of loops 25, the three small blocks 42 are formed. , Receiving basket 1
A method is adopted in which two are arranged side by side in the radial direction on the bottom surface of 0, and then one is stacked and arranged thereon.
Specifically, in such a method, for example, using a winding device having the above-described structure, the operation is performed according to the following procedure.

That is, first, the changing portion 30 of the controller 28 in the winding device stores the target position corresponding to the winding length of the wire tube 16. Here, the receiving basket 10 of the wire tube 16 is stored. The winding length inside (actually, this winding length is, as described above,
It is the length of the wire tube 16 sent out from the rolling machine. ) Reaches about 1000 m, the target position of the insertion position of the wire tube 16 is the outer target position radially outside the receiving basket 10: A (the position where the wire tube 16 indicated by a solid line in FIG. 2 is inserted). ) And the inner target position B inside the receiving basket 10 in the radial direction: B (in FIG. 2,
(A position where the wire tube 16 shown by the two-dot chain line is inserted) is stored so that it can be changed alternately.

Next, the wire tube 16 continuously supplied from a rolling machine (not shown) is guided by a guide table 22 and a guide roll 24 while being received by a receiving motor 18.
It is put into the receiving basket 10 rotated at a predetermined speed. At this time, until the winding length of the wire tube 16 into the receiving basket 10 reaches about 1000 m, the feeding position of the wire tube 16 in the radial direction of the receiving basket 10 is the outer target position: A, Material position detection sensor 26 and controller 2
8 controls the feeding position of the wire tube 16. That is, while the winding length of the wire tube 16 is 0 to about 1000 m, the input position of the wire tube 16 detected by the material position detection sensor 26 is not shifted from the outer target position: A. The feeding position of the wire tube 16 is controlled by increasing or decreasing the rotation speed of the receiving motor 18.

As a result, the wire tube material 1 of about 1000 m
6 is put into the receiving basket 10 at the outer target position: A and rolled up. Then, as shown in FIG. 3, a plurality of loops 25 a formed of a wire tube 16 extending from the tip to a length of about 1000 m, which are wound into the receiving basket 10, are stacked in the receiving basket 10. Block 42
Among them, in the first stage, a small block 42a having a large average diameter of the plurality of loops 25 formed in contact with the inner peripheral surface of the outer cylindrical wall portion 12 and arranged radially outside the receiving basket 10 is formed. It is.

At this time, the width of the small block 42a formed by the wire tube 16 wound into the receiving basket 10, that is, the difference between the maximum diameter and the minimum diameter of the plurality of loops 25a constituting the small block 42a: Since n is slightly smaller than 1/10 in the ratio: n / d with respect to the diameter: d of the receiving basket 10, the height of the small block 42a is also relatively low. The overall size of the small block 42a is relatively compact. Also,
As described above, such a small block 42a constitutes the small block 42a by being arranged in the receiving basket 10 in contact with the inner peripheral surface of the outer cylindrical wall portion 12. The collapse or the like of the plurality of loops 25a is prevented, so that the occurrence of a large radial displacement of the plurality of loops 25a can be prevented.

In addition, not only this small block 42a,
Even in the other two small blocks 42b and 42c,
The size is not particularly limited, and may be appropriately changed according to the length of winding of the wire tube 16 into the receiving basket 10. In order to prevent the occurrence of a large radial displacement in each of the loops 25, the above-described ratio: n / d is 1/15 <n / d <1 /
It is desirable to be within the range of 10.

When the winding length of the wire tube 16 exceeds about 1000 m, the receiving basket 1
The target position of the insertion position of the wire tube 16 in the radial direction of 0 is changed from the outer target position: A to the inner target position: B.
And the controller 28 controls the feeding position of the wire tube 16 by decelerating the receiving motor 18 so that the feeding position of the wire tube 16 coincides with the inner target position: B. Here, the target position is the outer target position:
When the target position is changed from A to the inner target position: B, the first to third compensating units 32 to 36 of the controller 28 reduce the excessive amount of the input position of the wire tube 16 as much as possible. Become. Further, even after the loading position of the wire tube 16 has been changed to the inner target position: B, the control by the controller 28 to make the loading position of the wire tube 16 coincide with the inner target position: B is performed by the controller 28. Until the winding length reaches about 2000 m.

In this manner, following the approximately 1000 m of the wire tube 16 forming the small block 42a, another approximately 1000 m of the wire tube 16 is placed in the receiving basket 10 with the inner target position: B. It is thrown in and rolled in at the matched position. The receiving basket 1 is made of a wire tube material 16 of about 1000 m wound into the receiving basket 10.
Of the plurality of small blocks 42 stacked in 0, 1
In a plurality of loops 25b having an average diameter smaller than the plurality of loops 25a constituting the small block 42a arranged radially outside the receiving basket 10 at the stage,
Small block 42b smaller in diameter than small block 42a
And the small block 42b is arranged inside the small block 42a arranged radially outward of the first stage at a predetermined distance from the inner cylindrical wall portion 14 of the receiving basket 10. It is.

Here, the two small blocks 42 arranged at the first stage in the receiving basket 10 are used.
Of the small blocks a and 42b, the small block 42b having a small diameter disposed radially inward is separated from the inner cylindrical wall portion 14 and arranged. Difference between the minimum diameter of the plurality of loops 25b constituting the loop and the maximum diameter of the plurality of loops 25a constituting the small-diameter small block 42a disposed outside the loop:
m is the diameter of the receiving basket 10: d,
Since their ratios are set to values slightly lower than 1/5 in m / d, the small block 42 having a large diameter is used.
The variation in the diameter of the loop 25a constituting the small block 42a and the diameter of the loop 25b constituting the small block 42b having a small diameter are made as small as possible.

However, the value of the ratio m / d in the plurality of small blocks 42 arranged in the receiving basket 10 in the radial direction is not limited to this. It can be variously changed depending on the size of each one, the number of the receiving baskets 10 arranged in the radial direction, and the like.
In order to suppress the variation in the diameter of the plurality of loops 25 constituting each small block 42, the value of the ratio: m / d is preferably set within the range of 2/15 <m / d <1/5. It will be.

Thereafter, when the winding length of the wire tube 16 exceeds about 2,000 m, the target position of the loading position of the wire tube 16 is changed from the inner target position: B to the outer target position: A again. And by the controller 28,
The receiving motor 18 is accelerated so that the input position of the wire tube 16 is controlled so that the input position of the wire tube 16 coincides with the outer target position: A. Even when the target position is changed, the first to third compensating units 32 to 36 of the controller 28 minimize the overshoot of the insertion position of the wire tube 16 as much as possible. Further, the control of the input position of the wire tube 16 after the change of the target position is continued until the supply of the wire tube 16 is completed.

As a result, following the wire tube 16 of about 1000 m forming the small block 42b, the remaining wire tube 16 of about 2000 m is thrown in at a position coinciding with the outer target position: A, and receiving is performed. Wrap in the basket 10. Then, the wire tube 16 of about 2000 m wound into the receiving basket 10
And a small block 4 disposed radially outside the first stage in the receiving basket 10.
2a, a plurality of loops 25c having substantially the same average diameter as the plurality of loops 25a form a small block 42c having substantially the same diameter as the small block 42a, and the small block 42c is formed into a receiving basket. In a state where the outer cylindrical wall portion 10 is positioned in contact with the inner peripheral surface of the outer cylindrical wall portion 12, it is stacked on the small block 42a arranged on the first stage radially outside.

Thus, in the present embodiment, three small blocks 42 each having a compact size and formed by a plurality of loops 25 each composed of the wire tube 16 put into the receiving basket 10 are formed. First, of the three small blocks 42a to 42c, the two small blocks 42a and 42b are arranged on the bottom surface of the receiving basket 10 as the first stage in the radial direction, and then,
Of the first-stage small blocks 42a and 42b, the second-stage small blocks 42c are stacked on the radially outer small blocks 42a, so that the wire tube 16 continuously supplied from a rolling machine (not shown). Is wound into the receiving basket 10 under the rotating condition.

Therefore, in this embodiment, for example, the wire tube 16 is placed at the same position over the entire length thereof.
Unlike the case where the wire tube 16 is charged into the receiving basket 10 or the case where the charging position is merely gradually changed inward in the radial direction according to the charging length, the wire tube material 16 to be charged is different.
Are overlapped without causing a large radial displacement, and all the loops 16
However, it can be neatly and stably wound.

Therefore, according to this embodiment,
The storage efficiency of the wire tube 16 in the receiving basket 10 can be sufficiently and stably enhanced. As a result, during the production process of the wire tube 16, it is possible to reduce the number of replacements of the receiving basket with the stoppage of the process as much as possible, thereby improving the production efficiency of the wire tube 16. It can be achieved very effectively.

In this embodiment, the continuously supplied wire tube 16 is supplied to the receiving basket 10.
Because it can be wound in a more orderly and stable manner,
For example, when rewinding the wire tube 16 from the receiving basket 10 at a high speed in order to perform a step of forming a groove on the inner surface of the wire tube 16, the wire tube 16 can be unwound in an orderly manner. Occurrence of scratches or cuts on the surface can be effectively prevented.

Moreover, in the present embodiment, among the small blocks 42 arranged in the receiving basket 10 in the radial direction, the small block 42b having the smaller diameter is arranged so as to be separated from the inner cylindrical wall portion 14. And the minimum diameter of the plurality of loops 25b constituting the small block 42b having the small diameter and the small block 4 having the small diameter.
Large block 42 arranged outside of 2b
a, the difference between the maximum diameter of the plurality of loops 25a, 25c constituting the loop 42c: m and the diameter of the receiving basket 10: d
Ratio: m / d is slightly smaller than 1/5, so that small blocks 42a and 42c having a large diameter
The diameter of the loops 25a and 25c constituting the small block 42b and the variation of the diameter of the loop 25b constituting the small block 42b are made as small as possible. When unwinding the tube 16 at a high speed, the rewind speed of the wire tube 16 does not need to be significantly changed, whereby the adjustment of such unwind speed can be advantageously simplified.

Therefore, according to the present embodiment as described above,
Improvement of the quality and the production efficiency or productivity of the final product such as the heat transfer tube with an inner groove processed from the wire tube 16 can be achieved very advantageously.

In this embodiment, the wire tube 16
The receiving position is determined by the combination of the material position detection sensor 26, the controller and the controller 28 so that the position of the material into the receiving basket 10 coincides with the target position changed according to the winding length of the wire tube 16. When the rotation speed of the basket 10 is adjusted, the wire tube 16 is automatically controlled so that the wire tube 16 is wound into the receiving basket 10 in a special arrangement as described above. In comparison with the case where the rotation speed of the receiving basket 10 is adjusted so that the wire tube 16 can be loaded at a predetermined target position by visual observation of an operator or the like, the continuously supplied wire tube 1
6 can be wound into the receiving basket 10 in a predetermined arrangement and more orderly and stably, and labor saving can be advantageously achieved by automation of such winding operation. . As a result, the production efficiency and / or productivity of the wire tube 16 can be further effectively improved.

In this embodiment, a device for winding a wire tube obtained by rolling one long raw tube by a known rolling machine into a receiving basket, Although a specific example of what applied the present invention to the winding method of the wire tube material using was described, the present invention provides a method in which one long raw tube is drawn by a predetermined drawing machine. It can be advantageously applied to any of a continuously supplied wire tube winding device and such a wire tube winding method, such as the obtained wire tube winding device and such a wire tube winding method. Some things are, of course.

Although the specific configuration of the present invention has been described in detail above, this is merely an example, and the present invention is not limited by the above description. In addition, although not enumerated one by one, the present invention is not limited to various modifications based on the knowledge of those skilled in the art.
Modifications, improvements, etc. can be made in embodiments, and any such embodiments may be included in the scope of the present invention unless departing from the spirit of the present invention. It goes without saying.

Incidentally, an experiment conducted by the present inventor to confirm the effect of the winding method of the wire tube according to the present invention will be described below.

First, a winding device having a receiving basket having a structure as shown in FIG. 1 and having an outer diameter of 3 m and a known rolling machine were prepared. Next, one long raw tube was rolled by the prepared rolling machine, and a wire tube material having a tube outer diameter of 9.52 mm was 35 mm from the rolling machine.
While feeding continuously at a speed of m / min, it was put into a receiving basket rotated around the axis.
Then, while the wire tube is loaded into the receiving basket, the material position detecting sensor detects the wire tube loading position in the radial direction of the receiving basket for only 120 seconds while the wire tube is loaded. The feeding position of the wire tube was controlled by the controller so that the position coincided with the outer target position: A (see FIG. 2).

As a result, when the controller does not control the insertion position of the wire tube, the insertion position of the wire tube is set at 6 mm in the radial direction of the receiving basket.
It fluctuated about 0 mm. On the other hand, while such control was being performed, the fluctuation of the feeding position of the wire tube in the radial direction of the receiving basket was suppressed to about 20 mm. From this, it can be clearly recognized that the control of the insertion position of the wire tube by the controller effectively suppresses the fluctuation of the insertion position of the wire tube in the radial direction of the receiving basket.

Further, all of the wire tubes having a predetermined length were wound up and stored in the receiving basket without controlling the charging position in the receiving basket as described above. Separately, all of the wire tubes having the same overall length were wound into the receiving basket while controlling the position of the wire tube into the receiving basket as described above. Thereafter, without controlling the loading position, the loops formed of the wire tube material wound into the receiving basket were displaced in the radial direction, and the loop was wound into the receiving basket while performing the control. The displacement in the radial direction of the plurality of loops formed of the wire tube was examined.

As a result, when the wire tube material is wound into the receiving basket without controlling the injection position, the positional deviation of the plurality of loops in the radial direction is limited to about 35 at the maximum.
It was about 0 mm. On the other hand, when the wire tube was wound into the receiving basket while controlling the injection position, the positional deviation of the plurality of loops in the radial direction was suppressed to about 100 mm at the maximum. Thus, it can be easily recognized that by performing such control, the wire tube material can be neatly wound into the receiving basket.

As is apparent from the above description, according to the method for winding a wire tube according to the present invention, a continuously supplied wire tube can be wound more orderly and stably into a receiving basket. As a result, it is possible to sufficiently improve the efficiency of storing the wire tube material in the receiving basket. As a result, the number of replacements of the receiving basket accompanying the stoppage of the production process of the wire tube can be reduced as much as possible, and the production efficiency of the wire tube can be increased extremely effectively.

When the wire tube winding device according to the present invention is used, the efficiency of storing the wire tube in the receiving basket can be more sufficiently improved while achieving labor saving.
