Description

Cable taping device {PATING APPARARUS FOR CABLE}

The present invention relates to a cable taping apparatus, and more particularly, to a cable taping apparatus capable of uniform taping by adjusting the tension according to the amount of tape wound on a tape drum.

In general, in the manufacturing process of various electric wires, an insulating tape is first wound on the outside of the wire, and then an insulating film is coated on the outer layer to complete the production. will do

Such a conventional taping device includes a tension control device as shown in FIG. 1 . A drum on which a tape is wound is mounted on the rotating shaft 31 , and the tape wound on the drum is wound on a cable through the first roller 22 , disconnection detectors 23 , 24 , and the second roller 25 . At this time, in the process of winding the tape around the cable, the roller body 21 rotates based on the hinge point 21a to pull the second roller 25 in the opposite direction to the rotation shaft 31, and the tension wound around the rotation shaft As the band 34 is loosened, the tension is released. As the amount of tape decreases, the force applied by the tape moving the second roller 25 increases. If the force is too large, the tension band 34 becomes too loose and the tape is unwound too easily. In this case, the spring can prevent the tension band 34 from loosening too much and the tape being too loose. As for the tension of the conventional taping device, the tension range of the spring 35 is constantly maintained as long as there is no change in the setting according to the setting of the tension control unit 36 .

However, as the tape wound on the drum in the taping device is unwound, as the tape wound diameter decreases from full to empty, the pulling force (tape tension) increases. Although the tension band 34 has to be loosened, the tension of the spring 35 is kept constant, so that the tape tension is increased. Accordingly, in the process of winding the tape on the cable, the degree of winding of the tape is not constant between the full winding and the empty winding, which may cause a problem in the quality of the tape.

The cable taping apparatus according to an embodiment of the present invention may tap the cable 500 while rotating in a direction perpendicular to the extension direction of the cable 500 . At this time, since the cable 500 performs taping while moving in the extension direction, taping may be performed in an oblique direction with respect to the extension direction of the cable 500 .

The tape 330 wound around the table winding unit 300 may be taped to the cable 500 through the roller unit 200 and the guide unit 400 .

The tape winding unit 300 may include a rotation shaft 310 , a tape drum 320 , a tape 330 , a tension band 340 , and a tension control unit 350 .

A tape drum 320 on which the tape 330 is wound may be mounted on the rotation shaft 310 . The tension band 340 may be disposed on the outer diameter of the rotation shaft. The tension band 340 may have one side connected to the end of the roller unit 200 , the other side connected to the tension control unit 100 , and may be disposed to contact the outer diameter of the rotation shaft 310 . The tension control unit 350 may set the tension of the tension band 340 according to a taping condition.

The roller unit 200 may include a roller body unit 210 , a hinge unit 211 , a first roller 220 , disconnection detecting units 230 and 240 , and a second roller 250 . The tape released from the tape drum 320 may be taped to the cable 500 by sequentially passing through the first roller 220 , the disconnection detecting units 230 , 240 , and the second roller 250 . The roller unit 200 may guide a path in which the tape released from the tape drum 320 is wound around the cable 500 .

The tape 330 passing through the roller unit 200 may be wound around the cable 500 via the guide unit 400 . The guide part 400 may include a guide rod support part 410 , a roller support part 420 , a third roller 421 , a fourth roller 423 , and guide rods 431 , 432 , 433 , 434 . .

The tape 330 having passed through the roller unit 200 is passed over the guide rods 431, 432, 433, and 434 via the third roller 421 and the fourth roller 423. The guide The rods 431 , 432 , 433 , and 434 extend in a direction parallel to the extension direction of the cable 500 , and come into contact with the tape 330 so that the surface of the tape 330 is the surface of the cable 330 . It can be guided to be parallel to the outer surface.

The tape 330 may be wound on the outer surface of the cable 500 in an oblique direction with respect to the extension direction of the cable 500 . The cable 500 is taped while moving in the opposite direction of the tape winding unit 300 . Accordingly, the tape 330 is pulled, and tension is generated between the cable 500 and the tape winding unit 300 .

In this case, the tape outer diameter sensing rod 120 may detect the outer diameter of the tape 330 so that the length of the tension control spring 145 increases as the tape 300 goes from full to empty. As the length of the extending tension control spring 145 decreases, the frictional force between the tension band 340 and the rotation shaft 310 decreases, and accordingly, the torque of the rotation shaft decreases. That is, since the torque of the rotation shaft 310 is also reduced according to the rate at which the outer diameter of the wound tape 330 is reduced, a constant tension can be maintained regardless of the outer diameter of the wound tape 330 . The tension control unit will be described in detail with reference to FIGS. 4 to 11 .

4 to 7 , the difference in torque and tension of the tape during full roll and empty roll is shown.

Tension according to the outer diameter around which the tape is wound and the torque may be defined by Equation 1 below.

Equation 1

where F is the tension, T is the torque, and r is the outer diameter of the tape.

When the tape is full, the outer diameter (r0) of the tape decreases as the tape becomes blank, and the outer diameter (r1) when the tape is parked is different. In the conventional cable taping apparatus, as shown in FIG. 5 , the outer diameter of the tape decreases from full to empty while the torque T is maintained almost constant at full and empty. Accordingly, the tension increases from the public domain to the full. In this case, since the tension is increased, it becomes difficult to wind the tape from the blank to the full volume, and a problem occurs in that it is difficult to achieve uniform taping.

However, in the cable taping apparatus according to an embodiment of the present invention, the outer diameter and torque of the tape decrease at the same rate from full to empty. Accordingly, the tension can be maintained uniformly from full to empty. Accordingly, in the process of taping, since the tension is constantly maintained regardless of the full or empty roll of the tape, a uniform taping operation may be performed and the taping quality may be improved.

The tape outer diameter sensing rod 120 is configured to directly contact the outer surface of the tape 330 wound on the tape drum 320 . Accordingly, when the tape is full, the tape outer diameter detecting rod 120a contacts the outer surface of the tape 330a and is inclined further downward, and when the tape is full wound, the tape outer diameter detecting rod 120b is on the outer surface of the tape 330b. When in contact, the outer diameter of the tape sensing rod (120b) comes into contact with the outer surface of the tape (330b) when it is in the park, and when it is empty, it can be inclined upward.

Accordingly, as shown in FIG. 8 , when changing from full to empty, the length at which the tension control spring 145 is stretched may be reduced by the size of the arrow.

2, 3 and 9 , the cable taping apparatus according to an embodiment of the present invention may include a tension control unit 100 .

The tension control unit 100 includes a body portion 110 , a tape outer diameter sensing rod 120 , a separation prevention bracket 130 , a separation prevention spring 135 , a tension control bracket 140 and a tension control spring 145 . can do.

The body part 110 is disposed on the roller body part 210 of the roller part 200 , and may extend in a direction perpendicular to the rotation direction of the rotation shaft 310 . For example, the body part 110 may have a cylindrical shape.

The tape outer diameter sensing rod 120 may have one end connected to the body portion and the other end in contact with the outer diameter of the tape.

The separation preventing bracket 130 may have a shape extending from the body portion to form a predetermined angle with the outer diameter sensing rod. One end of the separation prevention spring 135 is connected to the separation prevention bracket 130 , and the other end of the separation prevention spring 135 is formed to protrude from the roller body 210 to the separation prevention fastening part 215 . can be connected

The tension control bracket 140 has a shape extending from the body portion 110 to form a predetermined angle with the outer diameter sensing rod 120 , and may be connected to the tension band 340 . A tension control spring 145 and a tension control unit 350 may be disposed between the tension control bracket 140 and the tension band 340 .

The tape outer diameter sensing rod 120 is basically always in contact with the pad. The body portion 110 , the tape outer diameter sensing rod 120 , and the tension control bracket 140 are coupled to each other or integrally formed to move together. The tape outer diameter sensing rod 120 in contact with the outer surface of the tape 330 moves as the tape 330 goes from full to empty. Since the tape outer diameter detecting rod 120 and the body portion 110 are fixed, the body portion 110 rotates as the tape outer diameter detecting rod 120 moves. Since the body part 110 and the tension control bracket 140 are fixed, the tension control bracket 140 may also rotate as the body part 110 rotates. At this time, the tension control spring 145 is connected to the end of the tension control bracket 140, and the length of the tension control spring 145 can be compensated by the radius at which the tension control bracket 140 rotates.

As the tape 330 is wound around the cable 500 and the cable moves, the roller 200 rotates about the hinge point 211 so that the second roller 250 moves in the direction of the cable 500 . is pulled, and accordingly, the tension control spring 145 is stretched. In this case, the tape outer diameter sensing rod 120 may detect the outer diameter of the tape 330 so that the length of the tension control spring 145 increases as the tape 300 goes from full to empty. As the length of the extending tension control spring 145 decreases, the frictional force between the tension band 340 and the rotation shaft 310 decreases, and accordingly, the torque of the rotation shaft decreases. That is, since the torque of the rotation shaft 310 is also reduced according to the rate at which the outer diameter of the wound tape 330 is reduced, a constant tension can be maintained regardless of the outer diameter of the wound tape 330 .

As the outer diameter of the wound tape 330 decreases, the tape outer diameter sensing rod 120 moves upward. At this time, the separation prevention spring 135 pulls the tape outer diameter detecting rod 120 upward, and accordingly, the tape outer diameter detecting rod 120 is always on the outer surface of the wound tape 330 . You can stay in contact.

As the tape 330 changes from full to empty, the tape outer diameter sensing rod 120 moves upward, and accordingly, the length of the tension control spring 145 is reduced. Accordingly, the frictional force between the rotating shaft 310 and the tension band 340 becomes weaker as it changes from full to empty, and decreases as the torque of the rotating shaft 310 changes from full to empty. Since the outer diameter and torque of the wound tape 330 are reduced at the same rate, the tension applied to the tape may be kept constant even when the winding is changed from full to empty.

Referring to FIG. 10 , the tension control unit 100 of the cable taping apparatus according to an embodiment of the present invention may be formed such that an angle between the tape outer diameter sensing rod 120 and the tension control bracket 140 is 60 degrees. In addition, referring to FIG. 11 , the tension control unit 100 of the cable taping apparatus according to an embodiment of the present invention may be formed so that the angle between the tape outer diameter sensing rod 120 and the tension control bracket 140 is 135 degrees. there is.
