Remove the wire rod (10
2) Soak in a washing tank to remove the pickling solution attached to the
Next, the wire was lubricated and passed through a wire drawing die for wire drawing. [7] In this conventional wire drawing method, the processing of the coiled wire (1tJ2) in each process and the movement thereof were performed manually, which was extremely unproductive. Moreover, if the wire rod (102) wound into a coil shape is annealed as it is, the wire rods (1112) will partially adhere to each other due to the scales on their surfaces. When the coiled wire (102) in this state is immersed in the pickling tank, the pickling solution does not penetrate sufficiently into the bonded area, resulting in schooling. There is a problem in that the pickling solution remaining on the bonded area cannot be sufficiently washed away even if it is subsequently immersed in a washing tank. Therefore, conventionally, before pickling treatment,
Coiled wire (1υ
2) is manually handled and peeled off. This manual peeling operation of the wire rod (102) is also very unproductive.

Characteristics of a wire drawing method that aims to reduce the number of personnel required for the wire drawing process and improve productivity by performing the process efficiently by drawing the wire on a continuous line. However, is the wire rod in the heat-resistant material bobbin? After winding the bobbin into a full coil, the bobbin is put into a heat treatment furnace to anneal the wire, taken out of the furnace and sent to a fryer, and then pulled through a drawing device to rotate the fryer. The rotating member is rotated, and the rotating member is forcibly rotated in the opposite direction to the rotating direction.
The wire rod is fed out from the wire bobbin through a peeling roll installed in a fryer, and the wire rod is subjected to pickling, water washing, lubrication, etc., and then transferred to a wire drawing die. The wire drawing process is performed on a continuous line, and the rotation of the rotating member is stopped at the same time as the drawing device stops pulling the wire.

Hereinafter, the present invention will be described in detail based on the drawings.

through the water removal device, then through the lubricating tank 51 containing lubricating oil, then through the wire drawing die
Finally, it is wound onto a drawer bobbin 321 that is rotationally driven by a drawer device t311. Here, the drawer device 131) has a built-in device that stops the drawer bobbin 1321 after it has rotated a certain number of times in order to wind the wire rod (2) of a certain length onto the drawer bobbin 13z. Electric wiring is provided between the drawer device (31) and the electromagnetic brake (121) of the rotating member (Ill) so that the electromagnetic brake a2 is activated at the same time as the drawer bobbin 1311 stops rotating.

The removing device (261 is a T-shaped pipe joint as shown in FIG. 6) is installed at one end and the other end of the hollow housing C131.
On one end side, an ejector 5 (341) is formed with a synthetic resin female member having a tapered nozzle hole egg and a synthetic resin male member (381 are screwed together so that they can move forward and backward.

Then, in the female member example, a running wire (2
) A through hole (39) is provided on the same axis as the nozzle hole side to pass through the nozzle hole. Further, the hollow hatching door is provided with an inlet portion that communicates with a blower (not shown) for introducing pressurized air thereinto. In addition, in this embodiment, both the female member example and the female member C38) are screwed onto the hollow fitting T831 so that they can move forward and backward.
It may be formed integrally with the female member +361 'i hollow no. It may be possible to freely move forward or backward by being approached by someone.

Next, as shown in FIG. 4, the first water washing device (z7a) has a notch inside the upper part of the open surface of the cylindrical hollow member t411 having an axis in a direction perpendicular to the running direction of the wire rod (2). The same number of gaps as the running wire rods (2) to be processed are provided, and
The running wire (2) passes through this notch.

Also, the hollow member 1411 has water inside it through the water supply pipe 1411'i. It communicates with a water supply source (not shown) that supplies water.

Next, the second water washing device (27b) uses the wire rod (27b) as shown in FIG.

The outlet end of the pipe (440 running wire 12) communicates with a water supply source (not shown) that supplies water into the pipe decoy via the water supply pipe (4η').The pipe t431 is connected to the running wire (2) The outlet side is slanted so that the input side is ).

Although the embodiments of the apparatus for carrying out the method of the present invention have been described above,
Next, its action and effect will be explained. When the drawer bobbin 1321 K A! material (2) is wound up by the drawer device (311), the wire rod (2) is pulled in the direction toward the top mark in Fig. 1, and the rotating member (11) of the flyer device (3) Second
It rotates in the direction of arrow B in the figure, and the wire (2) is fed out from the bobbin (1). The 7-layer device (31 cents) to this bobbin (1) is the vertical shaft (8) and the shaft hole of the bobbin il+ (
7), it is simple and easy to work with as it only needs to be inserted through the shaft. Also, the rotating member (11) is rotatably and removably supported by the tapered shaft support (8a). Therefore, the rotating member (Kawane can be easily assembled without shifting the center of rotation) and the drawer device (311
Because the electromagnetic brake 92J operates at the same time as the pulling of the wire (2) stops due to inertia, the rotating member (II
) continues to feed out the wire rod (21) without stopping the rotation of the wire rod (
2) The ′i″′L does not have n, and the ′i″′L
? It does not require manpower or time to solve it. In addition, the rotation of the rotating member (11) is balanced by the wheel (I41) connected to the first arm (13a), and the wheel (I41) is connected to the first arm (13a).
Since 141 is made of rubber, the bobbin Ill upper flange (9
) has the effect of preventing the rotational speed of the rotating member (11) from becoming faster than the winding speed of the wire rod (12) due to inertia due to the frictional force between the wire rod (2) and the wire rod (2). It can be prevented. Then, the peeling roll 4 is rotationally driven in the direction opposite to the rotation of the rotating member (11), so that the peeling roll 4 moves the wire rod (2) in the direction of arrow C in FIG.
) will be pulled in the feeding direction. Now drawer device 1
If the rotating member (11 + 'i) is rotated with only the tensile force of 311 and the wire rod (2) is fed out from the ball 1-tll, the wire rod (2), which has become partially adhesive through the scale due to annealing, is bonded. Due to the force, the rotating member (11) may not rotate smoothly and the wire rod (2) may be cut. Peeling of the wire rod (2) is promoted, and the rotating member (11) rotates smoothly, so that the wire rod (2) is not cut.

Next, the tension adjusting device equalizes the tension acting on the wire rod (2), which helps to prevent the wire rod from sagging or breaking on the wire drawing line.

Next, when the running wire 12) with the hydrochloric acid solution attached to it by passing through the first pickling tank (25a)'fr passes through a part of the ejector of the removal device ω, it touches the inner surface of the nozzle hole punching of the female member j3Q. By adjusting the distance 11JIlk between the tips of the male members and introducing the pressure air from the inlet, the hydrochloric acid with K attached to the running wire (2) is jetted out immediately from the nozzle hole at high speed. It was possible to completely remove the sulfuric acid solution and water that had adhered to the running wire (2) in the second pickling tank (25b) and washing tank name. It was possible to completely remove the liquid by passing it through the device (support).Also, depending on the thickness of the running wire (2), the attached liquid could be removed. Although the speeds are different, by being able to adjust the distance between the inward surface of the nozzle hole and the front surface of the nozzle, the ejection speed will not increase unnecessarily, so the ejection of pressurized air will not cause unnecessary loud noise. Does it happen? Can it be prevented?

In the first water washing device (27a), the water fed to the hollow member 4L flows out through the notch, and the running wire (2) passes through this, making effective washing possible. Further, after passing through the washing tank 1281k, in the second washing unit @ (27b), the running wire (
The wire rod (2) runs through water flowing from the outlet side to the inlet side.
) can be completely washed with water by passing through it? I was able to do it.

In this way, the wire rod 12' (is finally drawn with the wire drawing die '301 k
Is a series of wire drawing processes performed manually? It can be carried out efficiently without the need for additional processing, and productivity can be improved.

According to the method of the present invention, a wire rod is fully wound around a bobbin made of a heat-resistant material, and the bobbin is directly placed in a heat treatment furnace to be annealed. The wire is taken out of the furnace and placed in a fryer, and then stretched by a drawer.The rotating member of the fryer is rotated to feed the wire from the bobbin, and the wire is pickled, washed, and washed. Since the process is carried out on a series of wire drawing lines where the wire is passed through the wire drawing die after being subjected to lubrication, it is possible to reduce the number of people required to process the coiled wire in each process and in between, as in the past.
That process? Productivity was improved by 2 by doing it efficiently. In particular, in the present invention, the wire rod is wound around a bobbin made of heat-resistant material and then annealed in a heat treatment furnace, and after annealing, the wound wire rod and bobbin are immediately sent to a fryer, which improves work efficiency. You can improve dramatically. In addition, since the wire rod that is unwound from the bobbin is unwound through a peeling roll, peeling of the wire rod that has become partially adhesive during schooling is promoted, and the rotation of the rotating member becomes smooth. The wire is not cut, which also helps the wire drawing process to be carried out on a continuous line. Furthermore, in order to stop the rotation of the rotating member at the same time as the pulling device stops pulling the wire, the rotation of the rotating member does not stop due to inertia and the wire does not continue to be drawn out and the wire becomes tangled, and the tangles are unraveled. It does not require manpower or time.
