The winding hook 2 winds the hard steel wire 20 for a predetermined turn, and the coiled hard steel wire 20 is sequentially dropped from below onto the carrier 11 from below. In order to adjust the falling state, a plurality of spring-biased wire rod pressers 7 are arranged around the winding hook 2.
This wire rod presser 7 elastically presses the hard steel wire 20 wound around the winding hook 2 and drops the hard steel wire 20 quantitatively.

The first guide roll 3 is, as shown in FIG.
It is installed so as to be vertically rotatable with respect to a mounting plate 8 provided just above the winding hook 2 so as to cover the upper surface of the winding hook 2. Thereby, the hard steel wire 20 is radiated in the radial direction C of the winding hook 2,
That is, it can be guided in the direction in which the second guide roll 4 is installed in a state parallel to the upper surface of the winding hook 2. The first guide roll 3 has a V-shaped groove 3 for moving the hard steel wire 20 to the second guide roll 4 without derailing.
a is formed.

The second guide roll 4 is rotatably installed at a predetermined position on the mounting plate 8 while being inclined with respect to the mounting plate 8. Thereby, the hard steel wire 20 can be guided from the first guide roll 3 along the outer periphery of the winding hook 2. The second guide roll 4 includes the first guide roll 3
A V-groove 4a is formed to move the hard steel wire 20 to the winding hook 2 without derailing in the same manner as described above.

The first straightening roll 5 is, as shown in FIG.
It is installed below the hard steel wire 20 that moves from the first guide roll 3 to the second guide roll 4, and is in a direction opposite to the direction of the curvature of the hard steel wire 20 attached by the first guide roll 3. A moving mechanism 9 for changing the pressing force is provided to apply a predetermined bending by pressing. The moving mechanism 9 is fixed to a predetermined position of the mounting plate 8 and moves the first straightening roll 5 in the vertical direction (perpendicular to the hard steel wire 20 moving from the first guide roll 3 to the second guide roll 4). Reciprocation in any direction). Thereby, the pressing force on the hard steel wire 20 can be changed. That is, when the first straightening roll 5 is moved upward, the winding diameter of the hard steel wire 20 by the winding hook 2 is increased, and when the first straightening roll 5 is moved downward, the winding diameter of the hard steel wire 20 by the winding hook 2 is reduced. . The first straightening roll 5 is also provided with a V-groove 5a in order to move the hard steel wire 20 to the second guide roll 4 without derailing.

The second straightening roll 6 is, as shown in FIG.

1 of size. This is because the straightening rolls 5, 6
However, when the diameter of the valley is less than 1/3, the adjustment of the correction amount becomes severe, so that it is difficult to adjust. When the diameter is more than 1/1, the correction effect is reduced. Therefore, in consideration of these points, the size of the valley diameter of each of the straightening rolls 5 and 6 is preferably about 1/2 of the size of each of the guide rolls 3 and 4.
Here, the “valley diameter of the V-groove” refers to the diameter of a virtual cylinder in contact with the bottom of the V-groove.

The operation of arranging the hard steel wires 20 in a coil shape by the vertical coiler 1 having such a configuration will be described below. The amount of correction by the first straightening roll 5 and the amount of correction by the second straightening roll 6 are adjusted in accordance with a predetermined winding diameter of the hard steel wire 20 by the winding hook 2. The hard steel wire 20 sent out from an upstream process, for example, a casting process, is fed from the upper portion A of the winding pot 2 to the first guide roll 3.
To the second guide roll 4 along the V groove 3a.
At this time, the bending of the hard steel wire 20 attached by the first guide roll 3 is caused by the first straightening roll 5 located between the first guide roll 3 and the second guide roll 4.
It is pressed in the direction in which the hard steel wire 20 bends, that is, the direction in which the hard steel wire 20 bends, so that a predetermined bending is given, so that the straightening is performed. The straightened hard steel wire 20 is used for the first straightening roll 5
From the second guide roll 4 to the winding hook 2 along the V groove 4a. At this time, the bending of the hard steel wire 20 attached by the second guide roll 4 is caused by the second straightening roll 6 located between the second guide roll 4 and the winding hook 2. It is pressed in the bending direction, that is, in the direction of the curvature of the hard steel wire 20 to give a predetermined bending, so that it is corrected.

Hard steel wire 2 straightened by second straightening roll 6
No. 0 is wound around the winding pot 2 for a predetermined turn, and the winding pot 2 forms the hard steel wire 20 into a coil shape by this winding and drops it quantitatively onto the transport carrier 11. Thus, the bending of the hard steel wire 20 applied by the first guide roll 3 is straightened by the single first straightening roll 5, and the hard steel wire applied by the second guide roll 4 is also straightened 20 is straightened by one second straightening roll 6 and is formed into a coil shape by the winding pot 2, so that the hard steel wire 20 can be given a fixed bending habit. Line 2
Even if the wire diameter of 0 changes, it is possible to obtain the same guide diameter without adjusting the correction amount of the first guide roll 3 and the second guide roll 4.

[0018]

As described above, according to the vertical coiler of the present invention, even if the wire diameter of the wire changes, the straightening amount of the first guide roll and the second guide roll can be adjusted without any adjustment. Since the coil having the same diameter can be formed by the winding hook, the setup time can be reduced and the workability can be improved. In addition, since the irregular drop of the wire is eliminated, tangling does not occur when the coil-formed wire is used.
