(The problem that the invention intends to solve)

In the cooling device of Patent Document 2, one end of the hollow portion of the wire coil is closed with a closing plate, and air is blown in from the other end side of the hollow portion to cool the wire coil.

Therefore, the air blown in from the other end side of the cavity portion flows toward the closing plate, and the linear advancing direction of the air is blocked by the closing plate, and further spreads in the circumferential direction on the one end side of the cavity portion of the wire coil.

As a result, the dynamic pressure of the air in the vicinity of one end side closed by the closing plate is higher than the dynamic pressure of the air on the other end side of the hollow portion of the wire coil into which the air is blown.

Therefore, there is a problem that the amount of air passing between the wires becomes significantly larger at a position near the one end side than the other end side of the cavity, and the wire coil cannot be uniformly cooled.

The present invention has been made in view of the aforementioned problems, and an object of the present invention is to provide a cooling device for a wire coil, which can more uniformly cool the wire coil. (Technical means to solve problems)

The cooling device for a wire coil according to the present invention is characterized by comprising: a covering member which is in contact with one side in the penetration direction of the wire coil so as to cover the wire coil; and an air supply hole provided in the penetration of the wire coil The other side of the direction, and the air is blown from the inside of the wire coil toward the covering member side; the covering member has a protrusion inserted into the inner side of the wire coil, and is provided between the wire coil and the outer peripheral surface of the protrusion. There is a gap, and also has a suspension support body for the above-mentioned covering member to be installed, the suspension support body has a suspension support portion suspended from above, and is suspended from the suspension support portion and guides the wire coil. A guide portion for the up-down movement of the aforementioned cover member in contact.

The said suspension support part is characterized in that it is suspended by the suspension member via the pulley arrange|positioned above.

The above-mentioned covering member is characterized in that a buffer material is provided at a portion facing the above-mentioned wire coil.

The aforementioned buffer material is characterized in that it is a metal mesh made of copper. (Compared to the efficacy of the prior art)

In the cooling device of the wire coil of the present invention, the wire coil can be cooled more uniformly. In addition, since the covering member is moved in the up-down direction guided by the guide portion suspended from the suspension support portion suspended from above, even if the number of stacks of the wire coils is different, the covering member may not be covered. Changes in the closed position (height) of the components can still eliminate malfunctions in the suspension operation.

Hereinafter, a preferred embodiment of the cooling device for the wire coil of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the cooling device (hereinafter referred to as a cooling device) 1 for a wire coil of the present embodiment is a device for cooling a wire coil 2 that winds a wire 2a in a cylindrical shape and The wire 2a after being wound is bound with a binding tape or the like at a plurality of places in the circumferential direction.

A hollow portion 2b is formed on the inner side of the cylindrical wire coil 2 in the penetration direction (axial direction).

As shown in FIGS. 1 and 2 , the cooling device 1 includes a mounting table 3 on which the wire coil 2 is mounted, a suspension support 4 suspended above the mounting table 3 , and a suspension provided so as to be movable in the vertical direction. The covering member 5 of the hanging support body 4 is suspended. The cover member 5 is guided by the suspension support body 4 so as to be movable in the up-down direction.

The mounting table 3 has an upper panel 3a formed in, for example, a flat rectangular shape, on which the wire coil 2 is mounted. An air supply hole 3b is arranged in the center of the upper panel 3a, and the diameter of the air supply hole 3b is smaller than the inner diameter of the wire coil 2 placed thereon.

The ventilation hole 3b is located on the lower end 2d side of the wire coil 2 in the penetrating direction of the wire coil 2 placed on the mounting table 3 .

Air supplied from a blower (not shown) is blown upward from the blower hole 3b. That is, the air is blown out toward the cover member 5 side in the hollow part 2b of the wire coil 2 mounted on the upper panel 3a.

Here, instead of the mounting table 3 , the wire coil 2 may be sequentially carried in and out using a roller or a chain conveyor. In this case, it is necessary to arrange a roller or a chain so as to avoid the upper part of the ventilation hole 3b to ensure ventilation.

The suspension support body 4 has: a suspended ceiling plate 7 as a suspension support part, suspended from above by a wire 6 or the like; 7a.

The suspended ceiling 7 is suspended by a wire 6 as a suspension member via a pulley 12 arranged above. The direction of the wire 6 is changed by the pulley 12, and the wire 6 is wound by the winch 13 provided on one side. Chains can also be used instead of wires 6, in which case sprockets are used instead of pulleys 12.

The suspended ceiling plate 7 can be formed, for example, in a flat rectangular shape, and is suspended so as to face the upper plate 3a at intervals in the up-down direction.

The rods 8 are formed in a cylindrical shape, and are respectively vertically installed at the four corners of the suspended ceiling plate 7 . The rod 8 is slidably inserted into the cover member 5 , whereby the cover member 5 is guided by the rod 8 so as to be movable in the vertical direction.

A stopper 8a for restricting further downward movement of the cover member 5 is provided at the lower end of the rod 8 .

The cover member 5 includes: a cover plate 9 formed in a substantially same planar rectangular shape as the suspended ceiling plate 7; a cylindrical protrusion 10 provided in the center of the lower surface 9a of the cover plate 9 so as to protrude downward; and a buffer material 11 , which is arranged on the lower surface 9a of the cover plate 9 .

Four corners of the cover plate 9 are provided with through holes 9b through which the rods 8 of the suspending support body 4 are inserted.

The protrusion 10 is formed with an outer diameter smaller than the inner diameter of the wire coil 2 . The lower surface 10a of the protrusion 10 is positioned above the upper panel 3a in a state where the protrusion 10 is inserted into the inner side of the wire coil 2 placed on the mounting table 3 and the covering member 5 is placed on the wire coil 2 .

The outer peripheral surface 10 b of the protrusion 10 inserted into the inner side of the wire coil 2 is spaced apart from the wire 2 a on the inner peripheral side of the wire coil 2 . That is, the gap S is provided between the wire coil 2 into which the protrusion 10 is inserted and the outer peripheral surface 10b of the protrusion 10 .

A buffer material 11 is provided on the lower surface 9a of the cover plate 9 at the portion facing the wire coil 2 except for the protrusion 10 .

The buffer material 11 is formed by, for example, stacking and installing a multi-layer copper metal mesh. The buffer material 11 may be an elastic member having heat resistance. Thereby, the surface of the upper end 2c of the wire coil 2 can be prevented from being scratched by the vibration of the cover plate 9, etc. at the time of air blowing.

When the wire coil 2 is not placed on the placing table 3 , as shown in FIG. 2 , the cover plate 9 of the cooling device 1 is positioned on the lower end side of the rod 8 due to its own weight, and is in contact with the stopper 8 a.

When the wire coil 2 is cooled by the cooling device 1, as shown in FIG. .

At this time, the wire coil 2 is arranged so as to surround the ventilation hole 3 b of the upper panel 3 a, and the cover plate 9 is placed on the wire coil 2 .

Thereby, the protrusion 10 is inserted into the hollow portion 2b inside the wire coil 2, the buffer material 11 contacts one side of the wire coil 2, that is, the upper end 2c, and the entire area on the wire coil 2 is covered by the covering member 5.

That is, the covering member 5 is in contact with the upper end 2 c of the wire coil 2 in the penetration direction of the wire coil 2 so as to cover the wire coil 2 .

When cooling a plurality of wire coils 2, the positions of the respective wire coils 2 are aligned and stacked so that the hollow portions 2b are continuous.

When the wire rod 2 is stacked on the mounting table 3, the wire rod 2 is mounted on the mounting table in a state where the suspended ceiling plate 7 and the cover plate 9 are suspended to a position higher than the mounting table 3 through the rod 8 3 on. The stacking height (stacking number) of the wire coil 2 is different each time. After the completion of placing the wire coil 2 on the placing table 3, the suspended ceiling plate 7 is lowered. After the cover plate 9 rides on the upper end 2c of the wire coil 2, while the rod 8 is slid relative to the cover plate 9, the suspended ceiling plate 7 is further lowered, and the suspended ceiling plate 7 stops at the set lowermost position each time.

In a state where the wire coil 2 is placed on the mounting table 3 and the covering member 5 is placed on the wire coil 2, air is blown toward the covering plate 9 side from the blower hole 3b.

At this time, the weight of the covering member 5 is set so that the covering member 5 does not float up due to wind pressure.

The air blown toward the cover plate 9 side from the blower hole 3b flows toward the protrusion 10 of the cover member 5 through the hollow portion 2b.

As shown in FIG. 4 , the air between the air supply hole 3 b and the protrusion 10 diffuses in the outer circumferential direction (from the inner side of the wire coil 2 to the outside) inside the wire coil 2 , and also enters between the wire coil 2 and the protrusion 10 . There is a gap S, and the air intruding into the gap S spreads in the outer circumferential direction (from the inner side of the wire coil 2 to the outer side) on the inside of the wire coil 2 while further facing the cover plate 9 side.

Therefore, in the case where the protruding portion 10 is not provided as shown in FIG. 5, the dynamic pressure of the air in the hollow portion 2b is extremely high only around the cover plate 9, but by providing the protruding portion 10, due to the effect of the gap S, the air Then, it is easy to escape from the periphery of the cover plate 9 , so that a substantially uniform dynamic pressure is generated in the entire cavity 2b from the lower end 2d to the upper end 2c of the wire coil 2 .

In short, according to the cooling device 1 of the present embodiment, when a plurality of wire coils 2 are stacked on the upper end 2c of the wire coil 2, since the upper end 2c of the wire coil 2 in the uppermost layer is in contact with the upper end 2c of the wire coil 2, the covering of the wire coil 2 is covered. The member 5 is provided with a protrusion 10 for inserting into the cavity 2b on the inner side of the wire coil 2, so as to reduce the dynamic pressure caused by the blowing to the side of the cover member 5, the cavity 2b The dynamic pressure inside is uniform. Therefore, the high dynamic pressure part is not only concentrated on the covering member 5 side, but also the amount of air passing between the wires 2a of the wire coil 2 can be made uniform throughout the wire coil 2 . Thereby, the wire coil 2 can be cooled more uniformly.

For example, since the covering member 5 is guided to move in the up-down direction by the rod 8 suspended from the suspended ceiling 7 suspended from above, even if, for example, the number of stacks of the wire coils 2 is different, by The closed position (height) of the covering member 5 is changed, and the wire 6 for suspending the suspension support 4 is still not loosened.

That is, when the wire 6 is arranged with the pulley 12, as shown in FIG. 6, when the suspended ceiling 7 is directly suspended by the wire 6, after the suspended ceiling 7 rides on the wire coil 2, the wire 6 may slack. And accidentally fell off the pulley 12 .

In this embodiment, since the cover plate 9 slides relative to the rod 8 of the suspended ceiling plate 7, the length of the wire 6 may be determined so that the uppermost position of the wire coil 2 is assumed to be under tension. Therefore, even after the suspended ceiling plate 7 is lowered and the cover plate 9 rides on the upper end 2c of the wire coil 2, the suspended ceiling plate 7 can continue to be lowered, regardless of the stacking height of the wire coil 2, since the wire 6 is stretched Therefore, the wire 6 does not fall off from the pulley 12, so that the malfunction in the suspension operation can be eliminated.

Since the covering member 5 is guided by a plurality of rods 8 vertically provided on the suspended ceiling 7 , it can prevent the covering member 5 from being displaced relative to the wire coil 2 .

That is, even when the suspended ceiling plate 7 is lowered while sliding with respect to the rod 8 , the cover member 5 is not displaced relative to the wire coil 2 .

Since the covering member 5 is provided with the buffer material 11 at the portion facing the wire rod 2 , it can surely prevent the wire rod 2 from being scratched by the covering member 5 .

FIG. 7 shows a modification of the aforementioned embodiment. The surface of the upper end 2c of the wire coil 2 is not necessarily a horizontal flat state, but may be inclined. In this modification, even when the surface of the upper end 2c of the wire coil 2 is inclined, the cover plate 9 can be provided on the surface in an inclined state, so that the upper end 2c of the wire coil 2 can be preferably closed.

First, the hole diameter of the insertion hole 9 b of the cover plate 9 is formed to be larger than the outer diameter of the rod 8 . Thereby, the cover plate 9 can be allowed to incline with respect to the rod 8, so that the cover plate 9 can be provided on the upper end 2c of the wire coil 2 according to the inclination of the surface of the upper end 2c.

In addition, it is preferable that the upper surface of the stopper 8a of the rod 8 is formed in a tapered shape that narrows as it goes upward, and the insertion hole 9b itself is formed into a tapered shape that can expand downward as it goes downward, or The same tapered guide member 14 is attached to the lower part of the insertion hole 9b.

In this way, when the suspension support body 4 rises, the stopper 8 a enters the insertion hole 9 b or the guide member 14 , so that the cover plate 9 can be returned to the horizontal and horizontal state and can be suspended in the center.

Of course, in the above-mentioned modification, the same effect as the above-mentioned embodiment can be obtained. As mentioned above, even if the surface of the upper end 2c of the wire coil 2 is inclined, the cover plate 9 can be appropriately provided to effectively cool the wire coil. 2.

The foregoing embodiments are used to understand the present invention but not to limit the scope of the present invention. Of course, changes and improvements can be made within the scope of the essential content of the present invention, and the equivalent improvements are also included in the present invention.
