1 is an exemplary view showing a configuration according to the present invention, Figure 2 is a plan view of the present invention, the present invention is a drum (1) is wound around the wire or cable having a constant diameter and the drum A motor 2 for rotating the motor 1, a worm gear part 3 provided on one side of the drum 1 to transmit the driving force of the motor 2 to the drum 1, and the worm gear part 3 Is connected to one side of the cable gear (4) installed on the other side of the drum (1), the cable gear (5) installed to engage with the cable feed gear (4), and the cable gear (5). A direction change gear (6) installed, a ball screw portion (7) rotated and operated by the direction change gear (6), a cable guide portion (8) moved along the ball screw portion (7), The drum 1, the motor 2, the turning gear 6, the ball screw portion 7 and the bracket (9) for supporting the cable guide (8).

The drum (1) is a place where the cable or the wire is wound, the worm gear portion (3) is installed on one side, the cable transfer gear (4) is installed on the other side, the worm gear portion by the operation of the motor (2) (3), the drum 1 and the cable feed gear 4 rotate integrally. In this case, the worm gear part 3, the drum 1, and the cable feed gear 4 have the same center line and are supported by the bracket 9.

The cable gear 5 receives the driving force of the motor 2 from the cable transfer gear 4 and transmits it to the direction change gear 6, and one side of the cable gear 4 is engaged with the direction change gear ( 6) has the same center line and is fixed and installed on one side.

The directional gear 6 is integrally operated with the cable gear 5, the cross-section is 'H' shape as shown in Figure 3 and 4, the first gear portion 61 and the second The gear portions 62 are formed so as to be continuous and located on different planes.

The first gear part 61 and the second gear part 62 have a length corresponding to half of the circumference of the directional gear 6 and are formed in parallel to each other at a constant distance, and have one end of the first gear part. The other end portion 612 of the first gear portion and the other end portion 622 of the second gear portion are viewed from the front so that the portion 611 and one end portion 621 of the second gear portion overlap each other when viewed from the front. It is formed on the turning gears 6 so as to maintain a constant interval. That is, the first gear part 61 and the second gear part 62 are not positioned on the same plane, so that both ends 611 and 612 of the first gear part and both ends 621 and 622 face each other (first step). The first and second gear parts 61 and 62 have a length corresponding to one-half the circumference of the directional gear, and the first gear 61 is located on the upper side about the center line of the directional gear 6. The second gear part 62 is positioned at the lower side, respectively.

The ball screw 7 is operated by the turning gear 6, and is mounted to the bracket 9 so that both ends are rotatable, as shown in FIGS. 2 and 5, and the first gear of the turning gear. A first gear pin 71 having one side engaged with the part 61 and a second gear installed at the lower portion of the first gear pin 71 and having one side meshed with the second gear part 62 of the direction change gear. A third gear pin 73 having the same center line as the first gear pin 71 and having one side engaged with the second gear pin 72, and the first and third gear pins 72. 71 and 73, the center line is provided, and is comprised by the conveyance part 74 which rotates forward and reverse by operation | movement of the 1st, 1st, 2nd and 3rd gear pins 71, 72 and 73. As shown in FIG. That is, the transfer part 74 is formed on one side of the ball screw 7, and the third and first gear pins 73 and 71 are sequentially formed on the other side, and the third gear pin 73 is formed. The second gear pin 72 is formed to be engaged with one side of the third gear pin 73 at the bottom of the. At this time, the distance between the center of the third gear pin 973 and the center of the second gear pin 72 is the overlapping portion of the first gear portion 61 and the second gear portion 62 formed in the direction change gear (6). It is provided so that the length A and the length A 'of the non-overlapping part of the 1st gear part 61 and the 2nd gear part 62 are the same.

The guide portion 8 is moved by the ball screw portion 7 to the left / right to adjust the position of the cable or wire wound on the drum, the movement of the ball screw portion 7 by the transfer portion 74 A ball feed nut 81, a cable feed roller 83 connected and installed by the cable feed nut 81 and the connecting portion 82, and a center line parallel to the ball screw portion 7; It is composed of a guide bar 84 installed on the screw portion 7 to guide the cable feed roller 83.

That is, the first and second gears are formed at one end 611 of the first gear part in which the ends of the first and second gear parts 61 and 62 of the directional gear are maintained at a predetermined interval by the driving force of the motor 2. When the turning gear 6 rotates to another end portion 612 of the first gear portion formed so that the ends of the portion overlap each other, the first gear pin 71 is rotated by the first gear portion 61, The transfer part 74 is rotated in one direction by the first gear pin 71, and the guide part 8 is moved in one direction by the transfer part 74.

In addition, since the length A of the overlapping portion A and the center of the first and second gear pins is the same as each other, the end portions 612 and the first gear pins 71 of the first gear portion 71 are the same. When the engagement is released, at the same time, one side end 622 of the second gear pin is engaged with the second gear pin 72 positioned below the first gear pin 71 to reduce the rotational force of the turning gear 6. 2 is transmitted to the gear pin (72). When the rotational force of the turning gear 6 is transmitted to the second gear pin 72 as described above, the second gear pin 72 rotates the third gear pin 73 and the third gear pin 73 By rotation, the transfer part 74 is rotated in the opposite direction to the rotation direction by the first gear pin 71, that is, reverse. As described above, when the transfer unit 74 rotates in reverse, the guide unit 8 that has moved in one direction along the transfer unit 74 is also reversely moved (home position).

That is, the cable feeding nut 81 which is slid along the conveying part 74 is moved left / right according to the rotational direction of the conveying part 74, and the cable is connected by the cable conveying nut 81 and the connection part 82. The transfer roller 83 is also moved left / right along the guide bar 84 by the rotation direction of the transfer unit 74.

In addition, since the lengths A ′ of the non-overlapping portions of the first and second gear portions and the centers of the first and second gear pins 61 and 62 are the same, the end portions 621 and the third of the second gear portion are the same. When the gear pin 73 is disengaged, at the same time, one end 611 of the first gear part is engaged with the first gear pin 71 located above the third gear pin 73 so as to shift the gear 6. Since the rotational force of) is transmitted to the transfer unit 64, the guide unit 8 is moved again. At this time, the guide portion 8 which is moved by the forward and reverse rotation of the ball screw 7, that is, the cable feed nut 81, the connection portion 82, and the cable feed roller 83 are drums in which cables are wound. It is to be moved within the length of the width.

According to the present invention, when the motor 2 rotates, the ball screw part 7 is rotated forward and reverse by the direction change gear 6 which is operated in one direction, and is moved left / right by the ball screw part 7. The cable or electric wire is wound around the drum 1 from left to right and right to left through the guide portion 8.

Thus, the present invention is to be able to continuously move the casing feed roller for guiding the cable or the wire to the left / right by using a single motor, reducing the manufacturing cost, thereby improving the economic efficiency.

In addition, the cable or electric wire can be wound around the drum from left to right and right to left by the transfer roller moved to the left and right, thereby maximizing the cable drum area, thereby minimizing the volume of the cable drum and There are many effects such as miniaturization of cable winding device.
