[0002]

2. Description of the Related Art A conventional rotary liquid spinning apparatus has a configuration as shown in FIG. 8 as disclosed in, for example, JP-A-55-64948. That is, the spinning device 10
Numeral 0 is constituted by a rotating water tank unit 110 and a jet injection unit 120. The rotating water tank unit 110 includes a cylindrical water tank 111, a water tank driving unit 112, a water supply pipe 113, and a drain pipe 114. The jet injection unit 120 includes a crucible 121, a traverse 122, and a heating coil 123. The water supply pipe 113, the drain pipe 114, and the jet injection unit 120 are inserted into the cylindrical water tank 111 through the opening 116. A rotational force is applied to the cylindrical water tank 111 through the shaft 115 by the water tank driving unit 112, and a liquid layer 130 is formed inside the cylindrical water tank 111 by centrifugal force generated by the rotational force. In addition, inside the crucible 121, the metal material 140 is heated and melted by the heating coil 123. And crucible 1
A predetermined pressure is applied to the metal material 140 in the pipe 21 through a pipe 124, and the crucible 12
1 is jetted into the liquid layer 130 as a jet 126 from the orifice 125. This jet 126
Is a continuous fine wire 15 cooled and solidified in the liquid layer 130.
0 is formed. The thin wire 150 formed by being injected into the liquid layer 130 is pressed and held against the bottom of the cylindrical water tank 111 by centrifugal force generated by the rotation of the cylindrical water tank 111. At this time, the jet injection unit 120 repeats the reciprocating motion in the direction indicated by the arrow F by the traverse 122 so that the fine lines 150 are uniformly distributed.

In this case, the liquid layer 1 in the cylindrical water tank 111 is
The adjustment of the water level of 30 and the circulation of the cooling water are performed by supplying the cooling water from the water supply pipe 113 and sucking the cooling water from the drain pipe 114. However, in the drainage method by suction, the tip of the stationary drain pipe 114 is inserted into the liquid layer 130 that moves in the rotation direction along with the rotation of the cylindrical water tank 111, so that it is arranged against the moving liquid. Will be. Therefore, there is a problem that the liquid layer 130 is agitated by the tip of the drain pipe 114, and the liquid layer 130 oscillates or waves, which hinders stable cooling and solidification of the jet 125.

[0004] FIG. 9 shows an example of Japanese Patent Application Laid-Open No. 1-306054.
Another conventional example as shown in FIG. The conventional example shown in FIG. 9 is an improvement of the cooling water supply / drain method of the conventional example shown in FIG. In other words, the spinning apparatus 200 for rotary liquid shown in FIG. 9 does not hinder stable cooling and solidification of the jet due to the water flow at the time of water supply. In FIG. 9, the spinning submerged spinning device 200 includes a rotary water tank 2
10, a jet injection unit 220, and a tray 230. The rotating water tank 210 includes a cylindrical water tank 211, a water tank driving section 212, a water supply pipe 213, and a weir 21.
4A, 214B, 214C, 214D, water level setting weir 21
5, and a drain hole 216. In addition, the jet injection unit 220 includes a crucible 221, a traverse 22
2, and the heating coil 223. The receiving tray 230 surrounds the cylindrical water tank 211. Then, the water supply pipe 213 and the jet injection unit 220 are connected to the cylindrical water tank 21.
One of the openings 217 is inserted into the inside.

[0005] Weirs 214A, 214B, 21 in FIG.
The operation functions other than 4C and 214D, the water level setting weir 215, the drain hole 216, and the tray 230 are the same as those of the conventional example shown in FIG. 8, and therefore the method of water supply and drainage will be described here.

At the time of jetting of the jet 224, the cooling water supplied from the water supply pipe 213 is supplied to the weirs 214A, 214B,
Circumferential end openings 218A, 21D of 214C, 214D
8B, 218C and 218D, and the water level setting weir 215
Overflows by an amount equal to or higher than the water level defined by the center side end of the, and is drained from the drain hole 216 by centrifugal force. Further, the drainage flows into the tray 230 and is drained from a drain port 231 provided as appropriate. Therefore, in this conventional example, the liquid layer 240
Since the water supply and drainage is performed without disturbing the surface layer portion, the stability at the time of jet coagulation is maintained.

[0007]

In this way, the produced fine wire is pressed and held against the bottom of the cylindrical water tank by the centrifugal force generated by the rotation of the cylindrical water tank, and is easily transported for collection and other methods. It is a bobbin wound because it is easy to use as a material for the purpose.
In winding the manufactured thin wire into a bobbin, the winding state of the thin wire is disturbed as the liquid layer held by centrifugal force collapses and drops when the rotation of the cylindrical water tank is stopped after injection. It is necessary that there is no. However, in the conventional example illustrated in FIG. 9, since the water supply and drainage is performed without disturbing the surface layer portion, there is an effect that the stability at the time of jet coagulation is maintained, but after the rotation of the rotary water tank portion is stopped, Since the cooling liquid that forms the liquid layer is discharged, the winding state of the thin wire is disturbed as the liquid layer collapses and falls, and the thin wire lacks stability in maintaining the winding shape after jetting.

Therefore, an attempt has been made to recover the line by draining after setting the horizontal axis vertically after the injection is completed (for example, JP-A-59-104250). Further, an attempt has been made to hold the manufactured fine wire at the bottom of a cylindrical water tank with a magnet (for example, JP-A-59-94526). However, in the former, there is a problem that the rotating shaft must be rotated from a horizontal state to a vertical state while rotating a large rotating body, and the device becomes large-scale and requires a large amount of space. doing. In the latter case, the manufactured fine wire must be made of a ferromagnetic material that can be attracted to a magnet, and has a problem that it is useless in the case of a non-ferromagnetic material.

According to the present invention, regardless of whether the metal material to be spun is a magnetic material or a non-magnetic material, even if the rotation of the rotary water tank is stopped after the end of the injection, the winding state of the fine wire is maintained at the bottom of the rotary water tank. It is an object of the present invention to provide a spinning in liquid spinning method and a spinning in liquid spinning apparatus that can be held.

[0010]

Means for Solving the Problems The inventors of the present invention have proposed that a thin wire, which is held without being twisted at the bottom of a rotating water tank, stops the rotation of the rotating water tank when the rotation of the rotating water tank is stopped after the injection is completed. If the liquid layer inside the rotary water tank was drained beforehand, the experiment confirmed that the thin wire itself remained in the rotary water tank without disturbing the row due to the tension of the wire itself, and the present invention was accomplished. .

That is, in order to achieve the above object, in the method of spinning in a rotating liquid according to the present invention, a cylindrical rotating water tank having a center of rotation in the horizontal direction is rotated, and the cooling liquid is continuously fed into the rotating water tank. And forming a cooling liquid layer by centrifugal force, and injecting the molten metal into the cooling liquid layer in a thin line form to solidify it, thereby producing a fine metal wire. Is closed during injection of the molten metal by a closing member rotatably supported with a rotation center coinciding with the rotation center of the rotary water tank, to obtain a predetermined amount of a fine metal wire. When terminating the production of fine metal wires, stop the injection of molten metal,
With the rotating water tank being rotated, the closing member is moved in the horizontal direction to open the drainage port, discharge the cooling liquid in the rotating water tank, and then stop the rotation of the rotating water tank. .

[0012] In order to achieve the above object, in the rotary liquid submerged spinning apparatus of the present invention, a cylindrical rotary water tank having a center of rotation in the horizontal direction is rotated, and the cooling liquid is continuously fed into the rotary water tank. A cooling liquid layer is formed by centrifugal force, and a molten metal is jetted into the cooling liquid layer in a thin line form and solidified to produce a thin metal wire. A part of which is provided with a drain port for discharging a cooling liquid constituting a cooling liquid layer formed by rotation of the rotary water tank, and has a rotation center coinciding with the rotation center of the rotary water tank and is rotatable. A drain port closing member is provided which is supported and moved in the horizontal direction so as to be in contact with and separated from the end of the rotary water tank so as to close / open the drain port.

[0013] An opening is provided at a predetermined height from the outer peripheral end of the rotary water tank.
Water level setting for maintaining a predetermined height of a cooling liquid layer formed by rotation in the rotary water tank by causing a part of the cooling liquid continuously supplied into the rotary water tank to overflow from the opening. It is effective to provide a weir function.

Further, it is preferable that the drain port closing member is movably engaged with one end of the rotary water tank in a horizontal direction so as to always rotate together with the rotary water tank.

Further, the drain port is formed by forming a through hole in a side wall of the rotary water tank, a projection is formed in the drain port closing member, and a projection of the drain port closing member is formed in the through hole. Preferably, they are engaged.

Furthermore, it is effective that the drain port closing member is constituted by a cylindrical member having both ends open and having a center of rotation coinciding with the center of rotation of the rotary water tank and rotatably supported.

[0017]

The rotary water tank is rotated with the closing member rotatably supported with the rotation center coincident with the rotation center of the cylindrical rotary water tank having the rotation center in the horizontal direction closed. Then, a cooling liquid is continuously supplied into the rotating water tank to form a cooling liquid layer by centrifugal force, and a molten metal is jetted into the cooling liquid layer in a fine line form and solidified to produce a fine metal wire. . When a predetermined amount of the fine metal wire is obtained, the injection of the molten metal is stopped in a state where the rotation of the rotary water tank is continued to terminate the production of the fine metal wire. After stopping the injection of the molten metal, the closing member is moved in the horizontal direction while the rotating water tank is rotated to open the drain port to discharge the cooling liquid in the rotating water tank, and then the rotation of the rotating water tank is started. Stop.

As described above, since the cooling liquid in the rotating water tank is discharged before the rotation of the rotating water tank is stopped, even if the rotation of the rotating water tank is stopped after the end of the injection, the winding state of the thin metal wire to be spun is changed. Do not break.

A drain port for discharging a cooling liquid constituting a cooling liquid layer formed by rotation of the rotary water tank is provided in a part of the cylindrical rotary water tank, and coincides with the rotation center of the rotary water tank. Since a drain port closing member that has a rotation center and is rotatably supported, and is configured to be able to close / open the drain port by moving in the horizontal direction so as to be in contact with or separated from the end of the rotary water tank, spinning is performed. Regardless of whether the metal material is a magnetic or non-magnetic material, even if the rotation of the rotary water tank is stopped after the end of the injection, the thin wire can be held at the bottom of the rotary water tank without breaking the winding state.

Further, an opening is provided for the drain port closing member at a predetermined height from the outer peripheral end of the press-contact of the rotary water tank, and a part of the cooling liquid continuously supplied into the rotary water tank is opened. By providing a function of a water level setting weir that maintains the height of the cooling liquid layer formed by rotation in the rotating water tank at a predetermined height by causing overflow, a constant water depth of the cooling liquid is always obtained, and cooling is performed. The temperature can be kept constant at all times, and the quality of the manufactured thin metal wire can be kept constant.

Furthermore, since the drain port closing member is movably engaged with one end of the rotating water tank in a horizontal direction, the member can always be rotated together with the rotating water tank.

Further, the drain port is constituted by a through hole formed in the side wall of the rotary water tank, and a projection is formed on the drain port closing member so that the projection of the drain port closing member is engaged with the through hole. Therefore, it is not necessary to provide an engagement hole for engaging with the drain port closing member separately from the drain port.

Furthermore, since the drain port closing member is constituted by a cylindrical member having a rotation center coinciding with the rotation center of the rotary water tank and having both ends open and rotatably supported, the drain port closing member is rotated by the drain port closing member. Does not block the side of the aquarium.

Next, a case where the cooling water of the liquid layer 21 is drained while the rotation of the rotary water tank 13 is maintained after the end of the injection of the molten metal material 6 will be described. First, with the rotating water tank 13 rotated, the handle 32 is appropriately rotated to horizontally move the support portion 32 of the drainage device 40 on the rail 31 in the direction indicated by the arrow D. Then, the drain hole 42 formed in the water level setting weir 41 that has been closed by the projection 46 of the drain hole opening / closing member 43 is opened. This open state is determined by the degree of movement of the projection 46.
Therefore, all the cooling water forming the liquid layer 21 from the drain hole 42 is drained. During this time, the cylindrical portion 14 keeps rotating by a drive source (not shown),
The rotation of the cylindrical portion 14 also maintains the rotation of the drain hole opening / closing member 43.

Thus, even if the rotation of the rotary water tank 13 is stopped after the drainage, the drainage does not fall, so that the winding state of the thin metal wire 12 is not disturbed. When the spinning of the metal material 6 is completed, the molten metal spraying unit 2 is drawn out of the rotary water tank 13, and after the liquid layer 21 is extracted, the rotation of the rotary water tank 13 is stopped to take out the spun material.

By fitting the projection 63 into the hole 18 of the cylindrical portion 14, the synchronization between the rotation of the rotary water tank 13 and the rotation of the water level setting weir 61 is guaranteed. The water level setting weir 61 has a V-shaped cross section at the bottom, and is formed by an end of a cylindrical support member 65 and a donut-shaped disc 62. 6
Reference numeral 4 denotes a space for inserting other necessary devices into the rotary water tank 13 without closing the drainage device 70 side of the rotary water tank 13.

Reference numeral 66 denotes a drain guide, which is formed at a position facing the water level setting weir 61 and guides cooling water overflowing from the water level setting weir 61 to a drain hole 67. The drainage hole 67 is a passage formed at the bottom of the drainage guide 67 provided in a gutter shape and protruding from an end of the cylindrical support member 65. A drain tray 35 is provided at an end of the gantry 23 for receiving cooling water drained from the drain holes 67. A drain port 36 is formed at the bottom of the drain catch 35. The drain port 36 is for discarding the cooling water discharged to the drain receiver 35 to the outside. Reference numeral 68 denotes a bearing that rotatably supports the cylindrical support member 65. The bearing 68 is provided on the support 69.

Next, the operation of this embodiment will be described.
The rotary water tank 13 of the rotary submerged spinning device 60 has a drive transmission unit 19 through a belt 20 from a drive source such as a motor (not shown).
It rotates by the driving force transmitted to. The liquid supplied by the water supply pipe 22 during rotation forms a liquid layer 21 inside the rotating water tank 13 by centrifugal force. At this time, the liquid layer 21
Is determined by the height of the weir of the water level setting weir 61. Therefore, the excessively supplied cooling water overflows from the upper end of the water level setting weir 61. In addition, this overflow water
The water is once received by the drain guide 66, but is discharged from the drain hole 67 to the drain receiver 35 using centrifugal force, and is processed through the drain 36.

Next, the case where the cooling water of the liquid layer 21 is drained while the rotation of the rotary water tank 13 is maintained after the end of the injection of the molten metal material 6 will be described. First, with the rotating water tank 13 rotated, the handle 69 is appropriately rotated to horizontally move the support portion 69 of the drainage device 70 on the rail 31 in the direction indicated by the arrow E. Then, until now the cylindrical part 1
The water level setting weir 61 that has been pressed into contact with 4 is separated, and a gap 37 is formed between the water level setting weir 61 and the cylindrical portion 14. The interval between the gaps 37 is determined by the degree of movement when the water level setting weir 61 moves away. Therefore, all the cooling water that has constituted the liquid layer 21 from the gap 37 is drained. During this time, the rotation of the cylindrical portion 14 is maintained by a drive source (not shown), and the rotation of the cylindrical portion 14 also maintains the rotation of the water level setting weir 61. Due to this rotation, the cylindrical portion 14 maintains a sufficient centrifugal force, so that the manufactured thin metal wire 12 keeps its position and winding shape. Thus, even if the rotation of the rotary water tank 13 is stopped after the drainage, the drainage does not fall, so that the winding state of the thin metal wire 12 is not disturbed. When the spinning of the metal material 6 is completed, the molten metal jetting unit 2 is drawn out of the rotary water tank 13 and after the liquid layer 21 is drawn out, the rotary water tank 13 is rotated.
Is stopped and the spun material is taken out.

FIG. 7 shows still another embodiment of the rotary liquid spinning apparatus according to the present invention. In the figure, FIG.
Since the members denoted by the same reference numerals as those in the illustrated embodiment have the same configuration and function, they will not be described again here. This embodiment is different from the embodiment shown in FIG. 6 in that the rotary water tank 13 has a cylindrical portion 1 similar to the embodiment shown in FIG.
4 has a weir 15 at one end and a water level setting weir 81 at the other end, and a hole 82 in a part of the cylindrical portion 14 of the rotary water tank 13.
The hole 82 is closed by a drainage device 80, the molten metal material 6 is injected, and then the drainage device 80 is moved horizontally to open the hole 82 and cool the inside of the rotary water tank 13. The point is that the liquid is discharged. In the figure,
Numeral 90 denotes a rotary liquid spinning device, and the other components are the same as those in the embodiment shown in FIG.

In order to produce a thin metal wire by injecting and solidifying in a shape, a drain port provided in a part of a cylindrical rotating water tank is rotatably supported with a rotation center coinciding with the rotation center of the rotating water tank. The closing member is closed by the closing member during the injection of the molten metal, the injection of the molten metal is stopped at the time of obtaining the predetermined amount of the fine metal wire and the production of the thin metal wire is terminated, and the closing member is rotated in the horizontal direction while rotating the rotary water tank. To drain the cooling liquid in the rotating water tank by opening the drain port, and then to stop the rotation of the rotating water tank,
Even if the rotation of the rotary water tank is stopped after the end of the injection, the winding state of the thin metal wire to be spun does not break.

A drain port for discharging a cooling liquid constituting a cooling liquid layer formed by the rotation of the rotary water tank is provided in a part of the cylindrical rotary water tank, and coincides with the rotation center of the rotary water tank. Since a drain port closing member that has a rotation center and is rotatably supported, and is configured to be able to close / open the drain port by moving in the horizontal direction so as to be in contact with or separated from the end of the rotary water tank, spinning is performed. Regardless of whether the metal material is a magnetic or non-magnetic material, even if the rotation of the rotary water tank is stopped after the end of the injection, the thin wire can be held at the bottom of the rotary water tank without breaking the winding state.

Further, an opening is provided for the drain port closing member at a predetermined height from an outer peripheral end of the press-contacting outer periphery of the rotary water tank, and a part of the cooling liquid continuously supplied into the rotary water tank is opened. By providing a function of a water level setting weir that maintains the height of the cooling liquid layer formed by rotation in the rotating water tank at a predetermined height by causing overflow, a constant water depth of the cooling liquid is always obtained, and cooling is performed. The temperature can be kept constant at all times, and the quality of the manufactured thin metal wire can be kept constant.

Further, since the drain port closing member is movably engaged with one end of the rotating water tank in the horizontal direction, it can be always rotated together with the rotating water tank.

The drain port is formed by a through hole formed in the side wall of the rotary water tank, and a projection is formed on the drain port closing member so that the projection of the drain port closing member is engaged with the through hole. Therefore, it is not necessary to provide an engagement hole for engaging with the drain port closing member separately from the drain port.

Further, since the drain port closing member is constituted by a cylindrical member having a rotation center coinciding with the rotation center of the rotary water tank and having both ends open and rotatably supported, the drain port closing member is rotated by the drain port closing member. Does not block the side of the aquarium.
