EXAMPLES Examples will be described below. (Embodiment 1) FIG. 1 is a perspective view showing an entire carbon lamp treatment device of the present invention. This carbon lamp treatment device includes a torch body 1 also serving as a reflector and a support 2 for supporting the torch body 1. Etc.

The torch body 1 is provided with a cover 4 covering the drive mechanism of the carbon electrode rods 3 and 3 shown in FIG. 2 on the outer surface of the rear portion thereof. The carbon electrode rod 3 is provided from the rear opening 1A of the torch body 1. 3 is exposed inside the torch body 1. The center line of the symmetrical arrangement of the carbon electrode rods 3, 3 is exactly aligned with the center line of the reflecting surface of the torch body 1. As shown in FIGS. 2 and 3, the driving mechanism of the carbon electrode rod 3 is arranged symmetrically in parallel with a base 5 made of an insulating material attached to the cover 4, and is rotatably supported by shafts 6 and 6. The axis line is orthogonal to the center line of the pair of metal holders 7 and 7 thus formed and the symmetrical arrangement of the metal holders 7 and 7 and is rotatably supported by the bearing 8 provided on the base 5. A drive gear 1 meshed with a shaft 9 and a driven gear 10 provided at one end of the shaft 9.
1 is composed of a motor 12 and the like for rotating and driving the shaft body 9.

The holder 7 has a metal electrode holding cylinder 13 attached to the front end thereof with a slight incline to the axis of the holder 7, and the carbon electrode rod 3 is inserted into the through hole of the electrode holding cylinder 13. Then, the carbon electrode rod 3 is fixedly held by tightening the tightening screw 14 that is screwed through the body of the electrode holding cylinder 13. The protective cover 15 is the electrode holding cylinder 13.
It covers the rear portion of the carbon electrode rod 3 penetrating through and protects it, and is attached to the holder 7.

The shaft body 9 is arranged so as to cross over a position slightly ahead of the shaft support portion of the holding body 7, and at the positions corresponding to the respective holding bodies 7, male screws 17 in opposite directions are cut on the outer peripheral portion. The cylindrical screw bodies 16 and 16 are inserted and fixed to the shaft body 9 so as to be electrically insulated.
As shown in FIG. 4, projections 18 projecting from the surface of the holder 7 are engaged with the valleys 17a of the male screws 6 and 16.

Therefore, when the shaft 9 rotates, the projection 18 receives a force from the valley 17a due to the screwing of the valley 17a of the male screw 17 to give the holding body 7 a rotational force about the shaft 6 and the valley. Move inside 17a. The holders 7, 7 on both sides rotate about the respective shafts 6, 6 in opposite directions, and
Depending on the direction of rotation, the tips are expanded or the tips are brought close to each other. Therefore, the carbon electrode rods 3 held by the electrode holding cylinders 13 are brought into contact with and separated from each other at their tips according to the movement of the holders 7.

A power cable 2 is provided at the rear of each holder 7, 7.
A terminal screw 19 for connecting 0 and 20 is provided, and the power supply cables 20 and 20, the holding bodies 7 and 7, the electrode holding cylinders 13 and 1,
A voltage can be applied to each of the carbon electrode rods 3 and 3 via 3. The energization control of the motor 12 and the power cables 20, 20 is performed by the control circuit unit 21 shown in FIG. 5. When the start switch SW is turned on, a voltage is applied to both carbon electrode rods 3 and 3 through the energizing path described above. At the same time, the control circuit unit 21 uses the start switch S
In conjunction with the input of W, the motor 12 is rotated in the direction in which the shaft body 9 is rotated in the direction in which the tips of the carbon electrode rods 3 are contacted.

The rotation of the motor 12 is transmitted to the shaft body 9 through the drive gear 11 and the driven gear 10, and the shaft body 9 rotates. When the shaft body 9 rotates, the left and right holders 7, 7 rotate about the shafts 6, 6 in the direction in which the tips approach each other, and eventually the carbon electrode rods 3, 3 held by the holders 7, 7. The tips of 3 will come into contact. Due to this contact, a current flows between the carbon electrode rods 3 and 3 to generate arc light.

When the current detection section 22 detects the current flowing at this time, the control circuit section 21 causes the timer (or counter) to operate.
At the same time when the time counting is started at 23, the rotation direction of the motor 12 is switched to the direction in which the carbon electrode rods 3 are separated from each other. By the reverse rotation of the motor 12, the shaft 9
The rotation direction of is reversed, and the left and right holders 7, 7 rotate in the direction of expanding the tips. In the control circuit unit 21, the timer 23
The rotation of the motor 12 is stopped when the (or counter) measures a certain time. The time from the reversal to the stop reaches the rotation angle by previously obtaining the rotation angle of the holding bodies 7 and 7 at which the distance between the tips of the carbon electrode rods 3 and 3 becomes a distance at which the optimum arc light amount can be obtained. Is determined based on the rotation time of the motor 12 up to.

Therefore, a series of operations until the distance between the tips of the carbon electrode rods 3, 3 is optimally set is automatically performed only by operating the start switch SW. 2 in FIG.
Reference numeral 8 is an insulating bush, and 24 in FIG. 5 is a reactor for limiting current. Example 2 In the above example, the base 5 made of an insulating material is used.
In addition, it is the same as the first embodiment in that the holders 7, 7 are rotatably and symmetrically rotatably supported, but as a drive mechanism, a linear movement of the screw body 26 is linearly moved through the link 25. It is different in that it uses a mechanism that converts it into the rotational motion of.

That is, as shown in FIG. 6, on the base 5 so that the axes of screw holes (not shown) in which female screws (not shown) are formed are aligned with the center lines of the holders 7, 7 symmetrically arranged. A metal support body 27 is arranged, and the screw body 22 is screwed into the screw hole of the support body 24 so as to be freely advanced. The screw body 26 has a driven gear 10 that meshes with the drive gear 11 of the motor 12 attached to one end, and a movable base 28 made of an insulating material is fixed to the other end that penetrates the support body 24. The movable table 28 rotatably supports one ends of links 25, 25 extending outward on the left and right sides, respectively. These links 25, 25
The other end of is rotatably supported at the rear of the holders 7, 7. The holders 7, 7 have attached at their tips an electrode holding cylinder 13 for holding and fixing the carbon electrode rods 3, 3.

Then, the motor 12 is rotated and the screw 26
When the screw is advanced to move forward or backward, the links 25 and 26 are operated in association with this movement, and the holding bodies 7 and 7 move the shafts 6 and 6.
Rotate around. By this rotation, the tips of the carbon electrode rods 3 and 3 held and fixed to the electrode holding cylinder 13 of the holding bodies 7 and 7 approach or separate as shown in FIG.

The control of the motor 12 is performed by using the control circuit section 21 of the first embodiment shown in FIG. 5, and the distance between the tips of the carbon electrode rods 3, 3 is set from the generation of the arc light in the first embodiment.
The procedure is similar to.
