1 is a schematic view of a wire winding apparatus according to the present invention, Figure 2 is an exploded perspective view showing a coupling structure of the drum, the support unit and the lifting bar of FIG.

Wire winding device according to the present invention is a device for winding the produced wire 10 is wound around the outer peripheral surface of the drum 100 to facilitate loading and transport, the wire 10 is limited to the outer peripheral surface of the drum 100 The biggest feature of the configuration is that it is configured to prevent entanglement by being wound in layers.

That is, the wire winding apparatus according to the present invention, the drum 100 and three or more slits 110 extending upwardly from the lower end in a cylindrical shape erected in the longitudinal direction toward the vertical direction and the drum 100 of the A rotary motor 200 for rotating the drum 100 with a longitudinal central axis as a rotating shaft, a support unit 300 which is inserted into the drum 100 and is conveyed up and down, and one side in the longitudinal direction of the drum ( 100) is extended downwards to be drawn into the inner side is coupled to the center block 310 and moved up and down, the elevating bar 400 for elevating the support unit 300 and the elevating bar 400 to move up and down It is configured to include a transfer motor (500). In this case, when the rotary motor 200 and the transfer motor 500 are exposed to the outside, there is a risk of safety accident. Therefore, the rotary motor 200 and the transfer motor 500 are preferably installed in the housing 20.

As shown in FIG. 2, the support unit 300 includes a center block 310 drawn into the drum 100 through a lower opening of the drum 100 and radially from the center block 310. The end portion extends through the slit 110 to protrude out of the drum 100 and then includes a mounting bar 320 that is bent or bent upwards. As shown in FIG. 1, the mounting bar 320 protrudes to the outer surface of the drum 100 so that the wire 10 wound on the outer circumferential surface of the drum 100 does not fall. As a component for supporting, at least three or more are preferably provided to stably support the wire 10 wound in a circle.

At this time, the wire 10 is not wound while compressing a very large force on the outer circumferential surface of the drum 100, but is simply wound to bend along the outer circumferential surface of the drum 100, the wire wound on the drum ( 10) is lowered as the support unit 300 is lowered.

Therefore, when using the wire winding apparatus according to the present invention, the wire 10 is wound around the outer circumferential surface of the drum 100, and the wire 10 newly supplied can be wound around the outer circumferential surface of the drum 100. In order to prevent the phenomenon in which the wire 10 is wound in multiple layers on the outer circumferential surface of the drum 100, that is, the wire 10 may be wound in one layer on the outer circumferential surface of the drum 100.

As such, when the wire 10 is wound in one layer on the outer circumferential surface of the drum 100, the curvature of each part of the wire 10 is set to be the same, thereby preventing entanglement when collected in one bundle. In addition, when the wire 10 is wound in multiple layers on the outer circumferential surface of the drum 100, the wire 10 is entangled as the wire 10 located in the high layer falls on the outer circumferential surface of the drum 100, Using the wire winding apparatus according to the present invention has the advantage that the entanglement is remarkably reduced because the wire 10 is not wound while being stacked in multiple layers as mentioned above.

In addition, in the wire winding apparatus according to the present invention, when the wire 10 is wound around the outer peripheral surface of the drum 100, the operation of automatically lowering the wire 10, which was previously wound on the drum 100, can be automatically made. It is preferred to be configured to. That is, the wire winding apparatus according to the present invention senses the height of the wire 10 supplied to the drum 100 side, so that when the height of the wire 10 rises above the reference value, the wire 10 falling signal is generated. The wire detection unit 700 for manipulating the switch 800 and the transfer motor 500 so that the lifting bar 400 is lowered by a predetermined distance when a signal for lowering the wire 10 is transmitted from the switch 800. It may be configured to further include a control unit 600 for driving.

In this case, the wire detector 700 is located above the wire 10 supplied to the drum 100, and the switch 800 is located above the wire detector 700. In addition, the wire sensing unit 700 is pushed by the rising wire 10 to press the switch 800, one side in the longitudinal direction extends downward toward the wire 10 and the other in the longitudinal direction of the switch 800 Extending upward toward, the operation of the wire detector 700 will be described in detail with reference to FIGS. 3 to 5.

On the other hand, when lowering the wire (10) previously wound on the drum 100, the wire 10 must be lowered at a very slow speed, the transfer motor 500 to directly lift the elevating bar (400) The problem that the lifting speed of the lifting bar 400 is difficult to finely adjust. Therefore, the wire winding device according to the present invention is installed so as to be able to rotate on the fixing plate 22 located above the drum 100 so that the lifting speed of the lifting bar 400 can be adjusted very finely. ) Is further provided with a rotating pulley 420 mounted to penetrate the inside, and the elevating bar 400 penetrates through the central axis of the rotating pulley 420 with a screwing structure, but is only capable of lifting and not rotating. Can be. As such, when the thread 410 is formed on the outer circumferential surface of the elevating bar 400, the elevating bar 400 is screwed to the center of the rotating pulley 420, and the transfer motor 500 rotates the rotating pulley 420. When rotated, the elevating bar 400 penetrating the rotary pulley 420 is raised or lowered by the distance of the thread 410 formed on the outer surface per one rotation of the rotary pulley 420. That is, when the rotational force of the transfer motor 500 is configured to be transmitted to the elevating bar 400 through the rotary pulley 420, the elevating bar 400 is elevated very slowly compared to the rotational speed of the conveying motor 500, There is an advantage that the lifting speed of the lifting bar 400 can be controlled very precisely.

On the other hand, when the wire 10 is wound around a certain length of the drum 100, the wire 10 should be cut and bundled into a bundle, if the thickness of the wire 10 is very thin, the length of the wire 10 It may be difficult to measure directly. Therefore, the wire winding apparatus according to the present invention measures the rotational speed of the drum 100 rather than directly measuring the length of the wire 10 wound on the drum 100, and the wire 10 wound on the drum 100. Is preferably configured to calculate the length.

That is, when the rotation speed sensor 210 for detecting the rotation speed of the drum 100 is installed on one side of the drum 100, the rotation speed of the drum 100 by multiplying the circumference of the drum 100 The length of the wire 10 wound around the drum 100 can be calculated. In addition, since the elevating bar 400 is elevated very slowly, the elevating distance of the elevating bar 400 cannot be accurately obtained by directly measuring the elevating bar 400.

Therefore, the wire winding device according to the present invention further includes a lifting distance detecting sensor 510 for measuring the rotation speed of the rotation pulley 420, and multiplies the rotation speed of the rotation pulley 420 by the pitch of the thread 410. Preferably, it is configured to calculate the lifting distance of the lifting bar 400.

In addition, while the support unit 300 supports the wire 10 wound around the outer circumferential surface of the drum 100, the support unit 300 must maintain the state coupled to the lower side of the elevating bar 400, on the outer circumferential surface of the drum 100. When the wire 10 is wound around a certain amount, the coupling with the lifting bar 400 should be released so that the wire 10 wound on the outer circumferential surface of the drum 100 can be drawn out below the drum 100. Therefore, the wire winding device according to the present invention allows the support unit 300 to be coupled to or separated from the elevating bar 400 according to a user's selection, and thus the longitudinal direction of the elevating bar 400 penetrating the center block 310. One side (in this embodiment, the lower side) may be further provided with a key pin 330 coupled in a removable structure.

As shown in FIG. 2, the key pin 330 is configured to be inserted into and mounted in a horizontal direction in a horizontal groove formed on a lower outer circumferential surface of the elevating bar 400. The center block 310, when the key pin 330 is mounted to the lower side of the elevating bar 400, the bottom surface is not seated on the upper surface of the key pin 330, and does not lower, the lower side of the elevating bar 400 from the When the key pin 330 is removed, it is removed from the elevating bar 400 and falls down.

In addition, the wire winding device according to the present invention, so that the wire 10 wound several times in the process of discharging and receiving the support unit 300 falling down from the lifting bar 400, the support unit ( A discharge unit 900 for receiving and transferring 300 may be further provided. As shown in FIG. 1, the discharge part 900 includes a tray 910 on which the support unit 300 removed from the elevating bar 400 is seated, and an elevating cylinder 920 for elevating the tray 910. And, the lifting cylinder 920 is mounted is configured to include a moving cart 930 which is movable along the rail 940. A process of receiving and transporting the support unit 300 by using the discharge unit 900 configured as described above will be described in detail with reference to FIGS. 6 and 7.

3 to 5 sequentially illustrate a process of the wire 10 being wound on the drum 100 descending when the wire 10 is wound on the drum 100.

When the wire 10 is to be wound on the drum 100 using the wire winding device according to the present invention, the lifting bar 400 is first lifted so that the support unit 300 is positioned at the middle of the drum 100. Thereafter, the wire 100 is wound around the outer circumferential surface of the drum 100 by rotating the drum 100.

The wire 10 is wound around the outer circumferential surface of the drum 100 spirally bar, as the number of times that the wire 10 surrounds the outer circumferential surface of the drum 100 increases, the wire 10 gradually becomes a drum The upper side of the outer circumferential surface of 100 is wrapped. As such, when the wire 10 surrounds the upper side of the drum 100, the supply path of the wire 10 provided to the drum 100 is gradually raised, and when the supply path of the wire 10 is raised above the reference value, As shown in FIG. 4, the wire 10 presses one side of the wire detector 700 in the longitudinal direction (lower side in this embodiment). The wire detection unit 700 is configured to be rotatable about the hinge axis 710, and as mentioned above, when one side in the longitudinal direction is pressed upward, the wire detection unit 700 rotates counterclockwise around the hinge axis 710. To press the switch 800.

The switch 800 pressed by the wire detection unit 700 transmits the support unit 300 falling signal to the control unit 600, and the control unit 600 operates the transfer motor 500 to raise and lower the bar 400. And it is lowered by a certain distance to the support unit 300 coupled thereto. When the support unit 300 is lowered, as shown in FIG. 5, the point at which the wire 10 surrounds the drum 100 is also lowered, and a supply path of the wire 10 provided to the drum 100 is also lowered. As it is lowered, the wire detector 700 returns to its original state, that is, the initial state of not pressing the switch 800.

When the wire winding apparatus according to the present invention is used, the position of the point at which the wire 10 is wound increases and the switch 800 is pressed, and the control unit 600 operates the transfer motor 500 to support the support unit ( The process of descending 300 is alternately repeated, so that the wire 10 can always be wound in one layer on the outer circumferential surface of the drum 100.

6 and 7 illustrate the operation of the discharge unit 900 included in the present invention.

When the wire 10 is wound on the outer circumferential surface of the drum 100 by a certain amount, the support unit 300 and the wire 10 loaded thereon are removed by removing the key pin 330 coupled to the bottom of the elevating bar 400. When the support unit 300 and the wire 10 loaded thereon fall on the floor, the wire 10 may be entangled by the drop impact force or the support unit 300 may be broken.

Therefore, to withdraw the support unit 300 and the wire 10 loaded therefrom from the drum 100, as shown in FIG. 1, the tray 910 should be located under the drum 100. When the distance between the bottom of the tray 100 and the bottom of the tray 910 is far, a large impact force may be generated while the support unit 300 is seated on the bottom of the tray 910.

The discharge unit 900 operates the lifting cylinder 920 as shown in FIG. 6 to raise the tray 910 so as to minimize the drop impact force of the support unit 300 descending from the drum 100. Then, the key pin 330 is removed from the elevating bar 400 so that the support unit 300 and the wire 10 loaded thereon are seated on the tray 910 as shown in FIG. 7.

After the support unit 300 and the wire 10 loaded thereon are seated on the tray 910, the lifting cylinder 920 is operated to lower the tray 910 and then move along the rail 940. The wire 10 is discharged by moving 930. At this time, the lifting of the tray 910 and the transfer of the moving cart 930 may be configured to be implemented by the operator's operation, when the amount of the wire 10 wound on the drum 100 is more than the reference value sequentially It may be automated to be implemented.

FIG. 8 is a schematic view illustrating a structure of a wire detector 700a according to another embodiment different from the wire detector described with reference to FIGS. 1 to 7, and FIG. 9 illustrates a state in which the wire detector of FIG. 8 is in contact with a wire.

As shown in FIG. 8 and FIG. 9, the wire detector 700a is in contact with the wire 10 to directly detect the movement of the wire 10, thereby stably detecting the thin wire 10. In addition, there is a feature in the configuration that it is configured to reliably detect the fine movement of the wire 10 by amplifying and outputting the distance traveled by the wire 10. That is, the wire sensing unit 700a according to another embodiment of the present invention is located at one side of the wire 10 supplied to the drum 100 so that one side in the longitudinal direction (the left side in the present embodiment) is the wire 10. A first link 710a contacted to receive the movement of the wire 10, a second link 720a primarily amplifying the movement of the first link 710a, and the second link 720a. It includes a third link 730a for amplifying and outputting the motion output from the) once again.

When the drum 100 is rotated by the operation of the rotary motor 200, the wire 10 supplied to the drum 100 is wound around the outer circumferential surface of the drum 100, wherein the wire 10 forms an upward spiral and the drum Since it is wound on (100), the more the number of times wound on the drum 100 is gradually wound the upper side of the drum (100). Therefore, as the wire 10 is wound in the state shown in FIG. 8, the supply path of the wire 10 toward the drum 100 is gradually increased, and the wire 10 supplied to the drum 100 is detected by the wire. The part 700a is pushed upward, and finally, the wire detector 700a presses the switch 800. The operator recognizes that the switch 800 is pressed to determine that the wire 10 has been raised to a predetermined point.

At this time, the wire detection unit 700a according to the present invention is configured to be able to reliably detect the fine movement of the wire 10 by outputting the movement of the side pressing the switch 800 larger than the movement of the wire 10. The first link 710a, the second link 720a and the third link 730a are preferably mounted at positions in which the hinge axis is biased toward the side to which the force is transmitted. That is, the first hinge shaft 712a is installed at a point biased toward one longitudinal side (side on which the roller 714a is mounted) in contact with the wire 10 of the first link 710a, and the second hinge shaft 710 722a is installed at a position biased to one side in the longitudinal direction coupled to the first link 710a of the second link 720a in a rotatable structure, and the third hinge shaft 732a is the second of the third links 730a. It is preferable to be installed at a point biased to one side in the longitudinal direction (the side on which the slide slit 734a is formed) connected to the link 720a.

As such, when the first hinge shaft 712a, the second hinge shaft 722a, and the third hinge shaft 732a are installed to one side in the longitudinal direction of each link, the longitudinal one side when the longitudinal one side is moved by an external force The movement distance of the other side in the longitudinal direction is output larger than the movement distance of. The movement of each link will be described in detail with reference to FIGS. 9 to 11.

On the other hand, when one end in the longitudinal direction of the first link 710a in contact with the wire 10 is formed in a simple rod shape, the friction is generated between the wire 10 and the first link 710a, as well as noise is generated, The first link 710a and the wire 10 may be damaged. Therefore, it is preferable that a roller 714a for rolling on the wire 10 is provided at one end in the longitudinal direction of the first link 710a, that is, the side in contact with the wire 10 so that rolling friction occurs instead of sliding friction. Rolling friction of the roller 714a has the advantage that the friction force is smaller than the sliding friction generated by the first link 710a is in direct contact with the wire 10 has the advantage of preventing damage and noise generation of each member.

10 is a schematic diagram of the wire detector 700a of FIG. 8 when the wire is raised, and FIG. 11 is a diagram illustrating an operation state of the wire detector 700a of FIG. 8 when the wire is raised.

9 to 11, the wire detector 700a includes three links that are sequentially connected, that is, a first link 710a, a second link 720a, and a third link 730a. In addition, one side of the first link 710a is raised in the longitudinal direction by the rising wire 10 to be rotated about the first hinge shaft 712a, and the second link 720a is the first link 710a. The third link 730a is successively rotated as the second link 720a is rotated as the second link 720a is rotated.

Since the first link 710a is configured to be rotatable about the first hinge shaft 712a provided at the middle portion, the supply path of the wire 10 is moved upwards so that the wire 10 is moved to the first link ( The first link 710a is rotated clockwise about the first hinge shaft 712a when the longitudinal one side (left in this embodiment) of the 710a is pushed upward. At this time, the first hinge shaft 712a is installed at a position biased to one side in the longitudinal direction, and when the first link 710a is rotated, the other length in the longitudinal direction of the first link 710a is longer than the one side in the longitudinal direction. It will appear big.

In addition, the second link 720a is coupled in a structure in which one side in the longitudinal direction (the right side in the present embodiment) is rotatable to the other side in the longitudinal direction of the first link 710a, the other side in the longitudinal direction extends to the left, and both ends in the longitudinal direction A second hinge shaft 722a arranged to be parallel to the first hinge shaft 712a is mounted therebetween, and is configured to be rotatable about the second hinge shaft 722a. Therefore, when the other longitudinal direction (right side in this embodiment) of the first link 710a is moved downward, the second link 720a is rotated clockwise about the second hinge axis 722a. The other side in the longitudinal direction of the two links 720a (left in this embodiment) is raised. The second hinge shaft 722a, which is a rotation axis of the second link 720a, is installed at a point biased to one longitudinal side (side connected to the first link 710a) of the second link 720a. When the link 720a is rotated, the other side in the longitudinal direction of the second link 720a is larger than the one in the longitudinal direction.

At this time, the first link 710a and the second link 720a are coupled to each other in a rotatable structure by a connecting hinge 721a, and the connecting hinge 721a is fitted into a through hole into which the connecting hinge 721a is inserted. When the circular shape is inserted into the structure, the first link 710 and the second link 720a form a triangular link structure. Therefore, the first hinge axis 712a and the second hinge axis 722a do not move. As long as the first link 710a and the second link 720a cannot be rotated. Therefore, it is preferable that the first link 710a and the second link 720a have a long hole shape in which a through hole into which the connection hinge 721a is inserted has a length to one side.

In addition, the third link 730a is formed with a slide slit 734a into which the other end of the second link 720a is inserted in one longitudinal direction (a side connected with the second link 720a). The second hinge shaft 722a is mounted in a rotatable structure about the third hinge shaft 732a. Accordingly, when the second link 720a is rotated clockwise about the second hinge axis 722a so that the other side in the longitudinal direction of the second link 720a (the left side in this embodiment) is raised, the second link 720a is raised. The other side in the longitudinal direction of the 720a pushes up one side in the longitudinal direction of the third link 730a while sliding in the direction drawn out of the slide slit 734a, and the third link 730a is the third hinge shaft. It rotates counterclockwise about 732a. At this time, if the width of the other side in the longitudinal direction of the second link (720a) is made to match the width of the slide slit 734a, the connection angle between the second link (720a) and the third link (730a) can not be changed. Therefore, the width of the slide slit 734a is formed to be larger than the width of the second link 720a, and the outer end of the second link 720a in contact with the left and right side walls of the slide slit 734a. It is preferable that the disc 724a to be provided.

On the other hand, the third link 730a is bent so that the other side in the longitudinal direction extends upwardly from the third hinge axis 732a and extends to the right bar, when the third link 730a is rotated counterclockwise. The other side in the longitudinal direction of the third link 730a is raised to press the switch 800. Therefore, the user can see that the switch 800 is pressed to know that the supply path of the wire 10 has reached the reference position. In this case, the switch 800 may generate an alarm output signal to notify the user when the switch 800 is pressed by the third link 730a, and the rotary motor so that the wire 10 is no longer wound on the drum 100. A signal may be generated to stop driving of the 200.

In addition, the wire sensing unit 700a is a distance at which the other side in the longitudinal direction of the third link 730a is raised from the distance (a) in which the one side in the longitudinal direction of the first link 710a is raised by the rise of the wire 10 ( In order that b) can be greatly amplified, it is preferable that the hinge axis serving as the center of rotation of each link is mounted to one side in the longitudinal direction of each link. That is, the first hinge shaft 712a is biased to the side closer to the roller 714a of the first link 710a, and the second hinge shaft 722a is biased to the side closer to the connecting hinge 721a. The hinge shaft 732a is preferably mounted to the side closer to the slide slit 734a. As such, when the

hinge shafts

712a, 722a, and 732a are mounted to one side in the longitudinal direction of each of the

links

710a, 720a, and 730a, even if the ascending distance of the wire 10 is small, the links are not visible. As a result of amplifying the moving distance in series, the moving distance of the finally output third link 730a becomes very large, that is, the position of the wire 10 can be more accurately measured.

As shown in FIGS. 12 and 13, the wire detector 700a may have a different rising distance from the other side in the longitudinal direction of the third link 730a even if the one rising distance in the longitudinal direction of the first link 710a is the same. It can be configured to be set. That is, the fixing position of the second hinge shaft 722a is configured to be changeable along the longitudinal direction of the second link 720a, and the second hinge shaft 722a is coupled to the second link 720a. Possible hinge fastening holes 726a can be arranged two or more apart in the longitudinal direction.

That is, as shown in FIG. 12, when the second hinge shaft 722a is installed in the hinge fastening hole 726a that is closest to the longitudinal side of the second link 720a among the plurality of hinge fastening holes 726a, the second hinge shaft 722a is provided. When one longitudinal side of the second link 720a is lowered, the ascending distance of the other side in the longitudinal direction of the second link 720a becomes maximum, and accordingly, the other longitudinal ascending distance of the third link 730a is also amplified to the maximum. It becomes possible.

On the contrary, as shown in FIG. 13, when the second hinge shaft 722a is installed in the hinge fastening hole 726a near the other side in the longitudinal direction among the plurality of hinge fastening holes 726a, the length of the second link 720a is provided. When the one side of the direction is lowered, since the ascending distance of the other side in the longitudinal direction of the second link (720a) is very small, accordingly, the other side of the longitudinal rise of the third link (730a) is also very short.

That is, the user can adjust the other side ascending distance in the longitudinal direction of the third link 730a by adjusting the mounting position of the second hinge shaft 722a, and thus, the wire detector 700 may be utilized for various purposes. There is an advantage.

As mentioned above, although this invention was demonstrated in detail using the preferable Example, the scope of the present invention is not limited to a specific Example and should be interpreted by the attached Claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
