FIG. 9 is a perspective view showing an overall configuration of an optical cable covering / separating apparatus according to the present invention.

9, an optical fiber covering / separating apparatus 200 according to the present invention includes a first roller 210 rotating in close contact with a semicircular optical cable, a second roller 210 coupled to the first roller 210, A second roller 230 formed on the lower portion of the first roller 210 and rotated in close contact with the semicircular optical cable, a second rotation shaft 240 coupled to the second roller 230 and transmitting a rotational force, And a power unit 400 (refer to FIG. 2) that generates a rotational force on the first rotation shaft 220 and the second rotation shaft 240. As shown in FIG.

The cloth separating apparatus 200 draws a semicircularly cut optical cable through the cut-off apparatus 100 to expose the metal shield surrounded by the cloth to the outside, thereby pressing the metal shield to separate the metal shield from the outer cloth.

The first rotating shaft 220 and the second rotating shaft 240 are rotated by receiving a rotational force from the power unit, and the first roller 210 and the second roller 230 are coupled to the center, respectively.

The first rotation shaft 220 and the second rotation shaft 240 should be formed so as to rotate in different directions so that the semicircular optical cable drawn into the first roller 210 and the second roller 230 can be moved inward .

For this, a sixth gear 421 and a seventh gear 422 are formed at the end of the second power transmission shaft 280. The sixth gear 421 is connected to the power unit 400 of FIG. 2, And the second power transmission shaft 280 is rotated. As the second power transmitting shaft 280 rotates, the seventh gear 422 rotates and rotates the second chain 425 engaged with the seventh gear 422.

When the second chain 425 is rotated, the eighth gear 423 of the first rotation shaft 220 located inside the second chain 425 is rotated in the same direction as the second chain 425, 1 roller 210 is rotated.

When the second chain 425 rotates, the ninth gear 424 of the second rotation shaft 240 is engaged with the outer side of the second chain 425 to rotate the second rotation shaft 240 in the direction opposite to the second chain 425, .

Accordingly, the first rotating shaft 220 and the second rotating shaft 240 can rotate in different directions.

The optical cable cut in a semicircular shape through the cut-off device 100 can be inserted between the first roller 210 and the second roller 230 through the input port 270, and the first roller 210 and the second roller 230, The semicircular optical cable inserted between the first and second rollers 230 and 230 is pressed between the first roller 210 and the second roller 230 rotating in different directions to move inward.

10 is a front view showing the interior of an optical cable covering / separating apparatus according to the present invention.

10, the second roller 230 of the optical cable covering / separating apparatus 200 according to the present invention has the diameter of the second roller 230 so as to be faster than that of the first roller 210 The second roller 230 is formed so as to have a circumferential velocity higher than that of the first roller 210. When the optical cable is inserted into the first roller 210, Is separated by a circumferential speed difference between the two rollers.

As the first roller 210 and the second roller 230 press the optical cable in a semicircular state, the outer cover and the metal shield having different radii are flattened and the coupling force between the outer cover and the metal shield is deteriorated.

The second roller 230 is formed to be 1.2-2 times larger than the diameter of the first roller 210 to separate the outer shield of the optical cable cut in the semicircular shape and the metal shield, So that the peripheral speed of the roller 210 is increased.

When the diameter of the second roller 230 is less than 1.2 times the diameter of the first roller 210, the difference in circumferential speed is not large enough to make it difficult to separate the metal shield and the outer sheath. It is too large to cause a slip and frictional heat is generated and can be pressed.

The first rotation shaft 220 and the second rotation shaft 240 rotate at the same rotational speed so that the first roller 210 and the second roller 230 rotate one wheel for the same time. However, since the diameter of the second roller 230 is larger than that of the first roller 210, the area of contact with the optical cable is increased more for the same period of time so that the circumferential speed of pushing the metal shield and the outer cover of the optical cable do.

Thus, the outer cover, which is moved in contact with the first roller 210 which is slower than the circumferential speed of the second roller 230, is moved more slowly than the metal shield which is in close contact with the second roller 230, A difference occurs in the moving distance of the cloth, so that it can be separated.

At this time, instead of forming the difference in diameter between the first roller 210 and the second roller 230, the diameter of the ninth gear 424 coupled to the second rotation shaft 240 is reduced, It is also possible to separate the metal shield and the outer sheath by the speed difference.

Further, protrusions or grooves are formed on the outer circumferential surfaces of the first roller 210 and the second roller 230 to widen the contact area between the metallic shield and the cover of the incoming optical cable.

The outer surface of the first roller 210 and the second roller 230 contacting the outer sheath and the metal shield may have protrusions or grooves formed in the inner surface thereof to widen the contact area and increase the frictional force, And the second roller 230, as shown in FIG.

The protrusions may be formed in a semicircular shape or may be formed continuously along the outer circumferential surface in a rectangular shape.

The width of the second roller 230 is larger than that of the first roller 210 and the both ends of the second roller 230 are formed to protrude so that the first roller 210 is in contact with the second roller 230 So that the optical cable is prevented from coming off to the side.

The width of the second roller 230 is set to be larger than that of the first roller 210 so that the semi-circular optical cable is passed between the first roller 210 and the second roller 230, And the first roller 210 is positioned between the protruded both ends of the second roller 230 so as to form the moving space 262 of the second roller 230 So that the center protrudes toward the center.

Thus, the inserted semicircular cable can not escape from the moving space 262 of the second roller 230 and the outer sheath and the metal shield are separated by the first roller 210 and the second roller 230.

11 is a side view of a side view of an optical cable covering / separating apparatus according to the present invention.

Bolts 261 are formed on the upper side and the lower side of the compression regulating device 260 so that the compression regulating device 260 can be moved and fixed.

A moving space 262 is formed in the first rotating shaft 220 so as to move upward and downward and a bolt 261 formed on the lower side or the upper side of the pressing adjusting device 260 is rotated to rotate the pressing adjusting device 260 So that it can be applied to various diameters of optical cables.

A knob 351 is formed on the outer side of the heating unit 350 so that the heating unit 350 can be opened and closed. So that the inside of the case 310 can be heated using a heat source generated in the heating device.

The heating device 352 continuously heats the inner coating of the optical cable so that the viscosity of the gel formed for fixing the communication line inside the inner coating of the optical cable contained in the wing 330 is weakened.

The wing portion 330 is in the form of a net so that the gel formed on the inner cover of the optical cable is discharged toward the case 310. The movable shaft 320 of Fig. 14 is coupled to the center of the wing portion 330, The rotational force transmitted to the pulley 321 through the power unit 400 rotates the movable shaft 320 of Fig. 14, thereby causing the wing 330 to rotate.

The gel whose viscosity is weakened by the heating unit 350 is pushed out toward the inner wall of the case 310 by the centrifugal force while rotating the wing portion 330.

Further, the inner case may be formed in a separate case (not shown), which is formed in a mesh form and can store the inner cover, so that the separation case can be supplied to the inlet 335 and recovered.

The rejection container 340 is formed as a container for storing the gel separated from the inner cover in the case 310 so as to perform the designated waste treatment, and is configured to be used by replacing the container.

FIG. 14 is a cross-sectional view showing an inner appearance of an optical cable gel separator according to the present invention.

14, a temperature sensor (not shown) is formed in the case 310 of the optical cable gel separator 300 according to the present invention, so that the heating unit 350 is set inside the case 310 (Not shown) for circulating the air is formed in the heating unit 350, so that the heated air uniformly heats the inside of the case 310. In this case,

The lower part of the case 310 further includes a ramp 311 such as a B so that the gel separated from the inner cover can flow into the receiver 340.

The inner coating of the optical cable contained in the wing portion 330 of the optical cable is heated by using the heating device 352 located on the lower surface of the heating portion 350 to weaken the viscosity of the gel formed on the inner coating, The temperature is raised.

The heating device 352 can heat the inside of the case 310 using a high frequency generator or an electric hot wire. A heat plate and a heat insulating material are installed on the inner side of the case 310 to reduce heat loss and increase the temperature quickly. You may.

At this time, a temperature sensor (not shown) is formed in the case 310 so that the inside temperature of the case 310 should not exceed 150 to 250 ° C. due to the heating device 352, The heating device 352 must be configured to automatically supply or block the power supply so as to maintain the set temperature.

When the internal temperature is less than 150 ° C, the viscosity of the gel does not change much, and even if the centrifugal force is used, the gel is prevented from coming out. When the internal temperature exceeds 250 ° C, the gel can be quickly evaporated and fixed in the inner coating.

Further, the heating unit 350 may circulate the inside air to generate a convection heat transfer, thereby forming a fan (not shown) for rapidly heating the inside of the optical cable, The temperature of the inside of the case 310 may be made uniform by circulating the air in the downward direction.

The inner coated gel heated by the heating device 352 and weak in viscosity is released from the inner coating due to the centrifugal force of the wing 330 rotating through the movable shaft 320, And is scattered to the inner side wall of the case 310.

As the time passes, the gel having a weak viscosity in the inner coat is removed from the inner cloth in a large amount. The gel is moved to the rejection 340 through the pipe 341 through the inclined path 311 formed at the lower portion of the case 310, The pipe 341 can be separated from the rejection 340 and discarded.

A water level sensor 342 for confirming the level of the gel is formed in the water rejection chamber 340. When the gel is collected over a predetermined amount, a warning sound may be generated to alert the user to replace the water level 340.

The movable shaft 320 rotates for 10 to 20 minutes to generate a centrifugal force to allow the gel to escape from the inner coating of the wing 330. The inner coating separated from the gel is collected at the wing 330, The communication line can be easily separated from the communication line, and the communication line separates the copper and the cloth using the chipping.

The rotational speed of the movable shaft 320 for generating the centrifugal force should be maintained at 1000 to 2000 rpm. If the rotational speed is less than 1000 rpm, the centrifugal force is too small to extract the gel. If the rotational speed exceeds 2000 rpm, 340 with the gel.

As described above, according to the optical cable cutting apparatus of the present invention, the outer cover of the optical cable and the metal shield are cut to separate the inner cover formed with the communication line formed therein, and the optical cable can be cut by one device regardless of the size of the optical cable , The fixing wire formed on the inner cover can be removed, and the blade can be used as needed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken as a limitation of the scope of the present invention. Or modify it. The scope of the invention should, therefore, be construed in light of the claims set forth to cover many of such variations.
