の調質に焼鈍される。In this case, as shown in FIG. 10, a copper tube 101 is first placed on the outer peripheral surface of an inner cylinder 102a of a bobbin 102.
With the left end position shown as the starting end 111, winding is performed in the right direction. The term "aligned winding" means that the copper tube 101 is densely wound so that one turn of the copper tube 101 and one turn adjacent thereto are in contact with each other, that is, without any gap. Next, after the copper tube 101 comes to the right end and the winding of the first layer is completed, the second layer is wound next from the right end to the left end. Conventionally, a copper tube portion 112 serving as a winding start end of the second layer
Are located on the gap between the copper tube portion, which is the terminal of the first layer, and the side plate 102b, and are sequentially turned to the left in the concave portions formed between the adjacent copper tube portions in the coil of the first layer. The copper pipe portion of the second layer is wound so as to fit. Thereafter, the third-layer coil is stacked on the second-layer coil. In this way, the copper tube 101 is wound in the tube axis direction to form a cylindrical single-layer coil, and then the copper coil 101 is wound thereon.
The winding method in which the cylindrical coil of the layer is formed by winding the copper tube 101 in the tube axis direction (opposite direction) is called traverse winding. Conventionally, the number of turns of the coil of each layer traversely wound is the same in each layer. By winding the copper tube 101 in this manner, the coil 110 having a small volume can be manufactured, and the space required for storage and transportation can be reduced. This LWC110
Is 100 to 500 kg per coil. The LWC manufactured in this manner is subjected to an unblocking process using a copper band or the like on the outermost periphery, the bobbin and the inner cylinder are removed, and the LWC is annealed to a predetermined quality by, for example, a roller hearth type continuous annealing furnace.

生産性が阻害される。At this time, during transportation and storage, that is, although the coil appearance is not recognized, when the coil is uncoiled, the outer surface of the copper tube wound near the center of the coil is discolored. May be. This discoloration is caused by the formation of an oxide film, and is called anko discoloration. Copper tube 101
If such discoloration occurs, the reliability when brazing the copper tube 101 may be reduced, and the appearance is not preferable, so that the copper tube 101 cannot be used and is discarded. For this reason, the yield decreases due to the occurrence of discoloration,
Productivity is impaired.

雑であり、装置コストが高いものとなる。Further, when the coil 110 is unwound with the coil axis being horizontal using the rotating device 103 shown in FIG. 11, if the pulling force of the copper tube 101 is large, the coil 110 is wound and tightened. By this tightening, the side plate 10
The copper tube portion adjacent to 2b enters into the gap between the side plate 102b and the copper tube 101 and becomes difficult to come off, and this portion is often deformed, which causes a reduction in yield and productivity. ing. FIG.
In the rotating device 103 shown in (1), it is necessary to support the coil in a cantilevered state by a horizontal rotating shaft, and to rotate and drive the rotating shaft to feed out the copper tube, which is structurally complicated and reduces the cost of the device. It will be expensive.

せる要因になっている。Furthermore, when the coil 110 is unwound from the outer surface of the coil with the coil axis being vertical by using the rotating device 4 shown in FIG. Therefore, a force in the direction in which the coil is tightened acts. For this reason, the copper tubes 101 rub against each other, causing scratches or deformation, which is a factor that reduces the yield and productivity.

Place on 114. In this case, the LWC 110 is arranged so that its coil axis is vertical and the starting end 111 at the time of coil winding existing on the inner surface side of the coil is on the upper side as shown in FIG.
Then, the copper tube start end 111 at the time of coil winding is pulled up, and the copper tube 101 is inserted into a curved tubular guide 115 installed above the table 114 to change the course thereof, and To supply. Thus, the coil 110
The copper tube 101 is pulled out of the coil 110 without rotating, and the coil 110 is unwound from its inner surface side.
Has a loop formed in a spiral shape, and while being pulled out through the guide 115, its winding habit is gradually eliminated. The 0.2% proof stress is 60 to 70 N / mm.
When a soft phosphorus deoxidized copper tube of about 2 is uncoiled by ETS, plastic working is applied to the copper tube, so that the 0.2% proof stress is 9%.
It rises to about 0 to 105 N / mm 2 .

より順にアンコイルされる。As described above, when the coil is uncoiled by ETS, a plurality of LWCs are usually placed on a pallet without a bobbin in order to eliminate the trouble of removing the inner cylinder and the side plate at the time of uncoiling. Transported, unpacked at the place of use, and placed on a pallet, the upper LWC
It is uncoiled in order.

At the time of uncoiling, there is no need to rotate the coil, and the copper tube drawn from the coil inner surface rises spirally and is guided to a predetermined copper tube processing place. Therefore, special equipment such as a vertical uncoiler or a turntable is not required. In addition, at the place where copper pipes are used, after receiving the LWC, it can be uncoiled in order from the upper LWC even in the state of multi-stack simply by transporting to the place of use and unpacking, so the above-mentioned problem of work efficiency is greatly reduced.

That is, since no force acts in the direction of tightening the coil due to the tension of the copper tube 101, deformation of the tube in the vertical uncoil or scratches or deformation of the tube in the horizontal uncoil is prevented, and the yield of the tube is greatly improved. It is believed that.

FIG. 1 is a cross-sectional view showing a method of manufacturing a level wound coil (LWC) 20 according to an embodiment of the present invention, and FIG. 2 is a schematic view showing an upper half of the LWC. The bobbin 2 has a cylindrical inner cylinder 2b and side plates 2a attached to both ends of the inner cylinder 2b. The bobbin 2 is connected to the rotating device 1 shown in FIG.
03, 104 are mounted on the rotating shaft. In the present embodiment, first, the copper tube 1 is positioned at the left end of the inner cylinder 2b, and this is used as the winding start end 21, and the bobbin 2 is moved to the rotating device 103,
The copper tube 1 is driven to rotate by 104, and is wound rightward in FIG. 1 around the inner tube 2b and is aligned and wound (traverse winding). That is, the copper tube 1 is wound around the inner tube 2b by aligned winding so that there is no gap in the copper tube portion and the copper tube 1 is always in contact therewith. In this embodiment, when the winding of the first-layer coil is completed, the end of the first-layer copper tube comes into contact with the side plate 2a. Therefore, the axial length of the inner cylinder 2b is an integral multiple of the outer diameter of the copper tube 1,
Assuming that the number of turns of the first layer coil is n and the outer diameter of the copper tube 1 is D, the length of the inner cylinder 2b is substantially nD. When the winding of the coil of the first layer is completed, the copper layer 22 at the beginning of the second layer is connected to the copper tube part at the end (n-th) of the coil of the first layer and immediately before (n-1). And positioned in the concave portion between the copper pipe portions, and sequentially wound in the leftward direction in FIG. At the left end of the second layer coil,
Since there is no room for one more coil to be inserted between the side plate 2a and the side plate 2a, the process proceeds to winding the third layer with a gap left. Therefore, the number of turns of the coil of the second layer is one less than the number of turns n of the coil of the first layer, and becomes n-1. 3
The coil of the layer is wound rightward in FIG. 1 n times as in the first layer. In this case, similarly to the first layer, the copper pipe portions on the left and right ends of the third layer are in contact with the side plate 2a. In the fourth layer, similarly to the second layer, the copper tube portion 23 at the start end is disposed so as to have a gap between the copper tube portion 23 and the side plate 2a, and the copper tube is wound leftward in FIG.

1), and the LWC 20 in which the winding directions of the odd-numbered layer coils and the even-numbered layer coils are opposite to each other is obtained. The LWC manufactured in this manner is subjected to an unblocking process on the outermost periphery with a copper band or the like, then the bobbin and the inner cylinder are removed, and annealed to a predetermined quality. If seizure occurs in the LWC during annealing, breakage, flaws, deformation, etc. will occur when uncoiling by ETS. Therefore, the coil tension, the number of coils in the winding direction and the stacking direction, It is necessary to select the pipe outer surface oil, annealing temperature, annealing time, annealing atmosphere, and the like.

円滑に引き出される。In the LWC 20 configured as described above, with the bobbin 2 removed, as shown in the schematic diagram of FIG. 3, the LWC 20 is set so that its coil axis is vertical and the winding start end 21 is upward. And the starting end 21 is pulled out upward. Then, the coil (first-layer coil) on the inner surface side of the LWC 20 is unwound and separated from the inner surface of the coil. Then, when the copper tube portion at the lowermost end (the rightmost end in FIG. 1) of the first layer coil separates from the inner surface of the coil,
The copper tube portion 22 at the lowermost (rightmost) winding start end of the second layer coil separates from the inner surface of the coil. In the present embodiment, the copper tube portion 22 at the second layer start end is the side plate 2a.
Is not in contact with the side plate 2a, and there is a gap between the copper tube portion 22 and the copper tube portion 22 on the upper layer (on the left) and the side plate 2a. Therefore, the copper tube portion 22 is easily and smoothly detached from the inner surface of the coil, and is smoothly pulled out from the coil 20.
