The present invention has been made in consideration of the above-mentioned background art, and aims to provide a hair implantation device that uses pre-cut short hair threads to tie the hair threads to a hair implantation net.

The present invention is a hair implantation device that includes a storage unit that stores a number of pre-cut hair strands in a row on top, and a hook that captures the hair strands from the storage unit. The hook rises from below the storage unit toward the storage unit, and the hook at the tip of the hook passes through a thread-removal hole in the storage unit and enters the row of hair strands above the storage unit, then descends, catching the center of the hair strand in the left-right direction and holding the hair strand folded in half.

The present invention is a hair implantation device that includes a storage unit that stores a number of pre-cut hair threads in a row on top, and a hook that captures the hair threads from the storage unit. The hook rises from below the storage unit toward the storage unit, and the hook at the tip of the hook passes through a thread-removal hole in the storage unit and enters the row of hair threads above the storage unit, then descends, hooking the center of the hair thread in the left-right direction and holding the hair thread folded in half, so that the first hook that moves forward and backward can capture the hair thread.

This shows the state in which the hair implantation yarn is twisted three times and tied to a hair implantation net by a hair implantation device of a form for implementing the invention, where Figure A is a front view seen from the side of the second hook in Figure 2, and Figure B is a back view seen from the side of the first hook in Figure 2.

The hair implantation device according to the embodiment of the invention shown in FIG. 1 includes an eccentric 10, a first hook 20, a second hook 30, a storage 40, a thread positioning bar 50, a thread drop bar 60, a thread retraction bar 70, a reversing roller 80, a magnet 90 shown in FIG. 6, a drive mechanism (not shown), and a control device 95. The control device 95 controls the drive mechanism, and the eccentric 10, the first hook 20, the second hook 30, the thread drop bar 60, and the thread retraction bar 70 each perform the first to eighteenth operations shown in FIG. 2 to FIG. 11, so that the hair threads 100 are captured one by one from the storage 40 and tied to the weft thread 202 of the hair implantation net 200 for implantation. The hair implantation net 200 includes both a case where it is made using a single thread made by twisting together multiple raw threads, and a case where it is made using a single raw thread without twisting together multiple raw threads.

The initial position of the hair implantation device when it operates is as shown in FIG. 1A. A number of short hair threads 100, which have been cut in advance, are stored in a long row on the stocker 40, which is placed above the eccentric 10, in a direction intersecting the direction of the center line of the eccentric 10. A hair implantation net 200, which is formed in a mesh shape and consists of a number of warp threads 201 and a number of weft threads 202, is deployed on the reversing roller 80 and the eccentric 10. The first hook 20 stops to the left of the eccentric 10, the second hook 30 stops below and to the right of the eccentric 10, the thread positioning bar 50 is located below and to the left of the thread take-up hole 42 provided in the center of the bottom 41 of the stocker 40 in the left-right direction, and the thread drop bar 60 and thread pull-in bar 70 stop between the thread positioning bar 50 and the eccentric 10, to the left of the thread positioning bar 50.

The length of the short hair thread 100 is trimmed to approximately twice the length of the hair of the finished wig, and can be longer or shorter than the left and right ends of the bottom 41 of the storage 40. However, if the length is long, as long as the part of the hair thread 100 that protrudes outward from the bottom 41 of the storage 40 does not hang vertically below the bottom 41 of the storage 40, this is preferable because it prevents the part of the hair thread 100 that protrudes outward from the bottom 41 of the storage 40 from rubbing against the left and right ends of the bottom 41 of the storage 40 and becoming damaged when the second hook 30 captures the hair thread 100 from the storage 40 and pulls it downward.

As shown in FIG. 1B, the storage unit 40 has left and right side walls 43 protruding upward from both left and right ends of the flat bottom 41, and the tops of the left and right side walls 43 are open and shaped like a gutter. Although a single storage unit 40 can be used, multiple storage units 40 are arranged in the left and right direction, and different types of hair yarns 100, such as hair yarns 100 of different colors, hair yarns 100 of the same color but different thicknesses, and hair yarns 100 of the same color or thickness but different hardness (elasticity), are mixed and then supplied individually to each storage unit 40, so that the color, thickness, or hair quality of the hair yarns 100 in the completed wig can be adjusted in advance.

The stocker 40 is fixed to the device main body (not shown) since it does not need to be moved. A plate-shaped weight (not shown) is placed on the hair thread 100 supplied to the stocker 40 to press down the hair thread 100, so that the hair thread 100 can be pulled out by the second hook 30. The weight may press down the hair thread 100 from above by the extension and contraction of a piston rod of an air cylinder that serves as a drive mechanism connected to both the device main body and the weight. The extension and contraction of the piston rod of the air cylinder may be controlled by the control device 95.

When the second hook 30 pulls out several hair threads 100, the hook 31 at the tip of the second hook 30 no longer hooks the hair thread 100, so each time several hair threads 100 are pulled out, the pressure applied to the hair thread 100 from the weight is released, the stocker 40 is struck, and the hair threads 100 are realigned. The time interval between releasing the pressure and realigning the hair threads 100 varies depending on the type of hair thread 100. The stocker 40 can be struck manually, but it may also be struck by a drive mechanism controlled by the control device 95.

The eccentric 10 is a member that secures the hair-implanting area of the hair-implanted net 200, and has a cylindrical net hanging part 11 with a center line extending left and right, a clearance part 12 provided in the net hanging part 11 so as to be recessed inward from the outer surface of the net hanging part 11, and shaft parts 13 provided at both ends of the net hanging part 11, and the center line extending left and right of the shaft parts 13 is offset radially outward from the center line extending left and right of the net hanging part 11 and is located at the circumferential center of the opening on the outer surface side of the net hanging part 11 in the clearance part 12.

The eccentric 10 is stopped so that the shaft 13 is rotatably supported by a bearing (not shown) provided on the device body (not shown), and the opening of the recess 12 faces left as shown in Figure 1A. In addition, the center line extending in the left-right direction of the shaft 13 overlaps with one weft thread 202-1 located at the circumferential center of the opening of the recess 12.

The opening width corresponding to the circumferential direction of the net hanging section 11 in the escape section 12 is determined based on the spacing of the weft threads 202 constituting the mesh of the flocked net 200, so that when the flocked net 200 is wrapped around the outer surface of the net hanging section 11 and one weft thread 202-1 is located at the circumferential center of the opening width of the escape section 12, one weft thread 202-2 of the two weft threads 202-2 and 202-3 adjacent to the one weft thread 202-1 located at the center is located around one side edge of the opening of the escape section 12, and another weft thread 202-3 of the two weft threads 202-2 and 202-3 is located around the other side edge of the opening of the escape section 12. Note that the opening width corresponding to the circumferential direction of the net hanging section 11 in the escape section 12 may be equal to or greater than the width of the weft threads 202-2 and 202-3.

The first hook 20 is a member for implanting the hair thread 100 in the hair implantation net 200, and is equipped with a hook 21 at the tip and a latch 22 for opening and closing the needle opening of the hook 21. One end of the latch 22 is rotatably connected to the first hook 20 by an axis not shown, and the other end of the latch 22 rotates around the axis to open and close the needle opening. In the initial state, as shown in Figure 1A, the first hook 20 moves away from the eccentric 10 to the left and stops at a position facing the opening of the escape portion 12, and the latch 22 closes the needle opening.

The first hooks 20 are operated by a drive mechanism controlled by the control device 95 to implant the hair thread 100. The first hooks 20 are arranged side by side in the same manner as the multiple second hooks 30 shown in FIG. 1B. A group of multiple first hooks 20 are operated together by a drive mechanism controlled by the control device to implant the hair thread 100 in the hair implantation net 200. The first hooks 20 and the second hooks 30 are in one-to-one correspondence. The number of first hooks 20 and second hooks 30 is not limited to multiple, and may be single.

The second hook 30 is a member that captures the hair thread 100 from the stocker 40, and has a hook 31 at its tip that can capture one hair thread 100. In the initial state, as shown in FIG. 1A, the second hook 30 moves to the right from the eccentric 10 and stops at a position between the eccentric 10 and the reversing roller 80, and the needle mouth 32 of the hook 31 faces the front side of the paper in FIG. 1A. Also, as shown in FIG. 1B, the second hook 30 is arranged in a row on the left and right. A group of the second hooks 30 operates together with a drive mechanism controlled by the control device 95 to capture the hair thread 100. Although the hook 31 captures one hair thread 100, the hook 31 may capture two or more hair threads 100.

The thread positioning bar 50 is a member that guides the hair thread 100 pulled out from the stocker 40 by the second hook 30 to a predetermined position. As shown in FIG. 1B, a plurality of thread guides 51 are provided around the cylindrical outer peripheral surface, recessed toward the center line from the cylindrical outer peripheral surface having a center line extending left and right. The left and right ends of the thread positioning bar 50 may be fixed to the device body, but by providing them rotatably, the thread positioning bar 50 is rotated by the hair thread 100 pulled out from the stocker 40 by the second hook 30, and the part of the hair thread 100 pulled out by the second hook 30 can be prevented from being rubbed and damaged by the thread guide 51, which is preferable. The number of thread guides 51 is the same as the number of second hooks 30.

The thread drop bar 60 vibrates up and down by a drive mechanism controlled by the control device 95 during the process in which the hair thread 100 implanted in the hair implant net 200 is pulled in by the thread pull-in bar 70, and brushes off the end of the hair thread 100 being pulled in by the thread pull-in bar 70, and styles the hair thread 100 downward.

The thread retraction bar 70 moves back and forth by a drive mechanism controlled by the control device 95, and retracts the hair thread 100 implanted in the hair implantation net 200. As a pre-step of implanting the hair thread 100 in the hair implantation net 200 with the first hook 20, the latch 22 of the first hook 20 touches the hair thread 100 and closes when the first hook 20 enters between the hair thread 100 folded in half between the second hook 30 and the stocker 40 and moves back. The magnet 90 is attached to the device body so that the magnet 90 attracts and opens the closed latch 22 with a magnetic force. Either a permanent magnet or an electromagnet can be used, but if an electromagnet is used, the electromagnet can generate a magnetic force only when the electromagnet is controlled by the control device 95 to open the closed latch 22. The reversing roller 80 is attached to the device body.

The operation of the hair implantation device will be described with reference to Figures 2 to 11. As shown in Figure 2, the front part of the thread pull-in bar 70 advances and stops at a position beyond the thread take-up hole 42 of the stocker 40 and the second hook 30 to the right in Figure B by the thread pull-in bar forward movement as the first movement. Next, the second hook 30 rises and the hook 31 passes through the thread take-up hole 42 and enters the row of multiple hair threads 100 inside the stocker 40, then descends and stops at the initial position. In this second hook ascending movement, the hook 31 descends and stops while hooking the center part of one hair thread 100 in the left-right direction, so that the one hair thread 100 is folded in two between the stocker 40 and the second hook 30. As shown in Figure 2B, the hair threads 100 folded in half by the multiple second hooks 30 are stored one by one in each of the multiple thread guides 51 of the thread positioning bar 50, so that the position of each hair thread 100 spread out on the second hooks 30 and the stocker 40 is secured in a predetermined position, and the first hooks 20 can properly capture each hair thread 100.

In addition, as the hook 21 of the first hook 20 passes under the weft thread 202-1 by the forward movement of the first hook as the third movement, the latch 22 interferes with the weft thread 202-1 and opens, and the mouth of the hook 21 passes over the weft thread 202-1 from left to right and is accommodated in the escape portion 12 to reach the position shown by the imaginary line. After that, as the fourth movement, the first hook 20 retreats from the position shown by the imaginary line to the position shown by the solid line, and the hook 21 hooks the weft thread 202-1.

3, as the fifth operation, the eccentric 1/4 rotation operation rotates the shaft 13 of the eccentric 10 in one direction by a drive mechanism (not shown), and the net hooking part 11 rotates downward from the position shown by the imaginary line to the position shown by the solid line about the center line of the shaft 13, the opening of the escape part 12 faces upward, and the rotation of the shaft 13 in one direction stops. As a result, the eccentric 10 moves below the first hook 20 and the weft thread 202-1 without moving the first hook 20 and the weft thread 202-1. The phrase "without moving the first hook 20 and the weft thread 202-1" also includes the case where the tip of the first hook 20 trembles due to the elasticity of the hair-implanted net 200 when the eccentric 10 moves downward. This movement of the eccentric 10 from the position shown by the imaginary line to the position shown by the solid line allows the first hook 20 to pass above the eccentric 10 and move to the side between the hair thread 100 that is folded in half between the stocker 40 and the second hook 30. By rotating the eccentric 10 downward from the position shown by the imaginary line to the position shown by the solid line and moving it to a position below the first hook 20, the weft thread 202-1 is not overloaded and does not break, and the first hook 20 is not overloaded and does not break.

In addition, it is also possible to rotate the eccentric 10 downward from the position shown by the imaginary line to the position shown by the solid line, while the first hook 20 has the weft thread 202-1 hooked, by the control of the control device 95, using a drive mechanism (not shown) to rotate the eccentric 10 about the center line of the net hooking part 11 and move the first hook 20 along the movement of the weft thread 202-1 that it has captured. At that time, the first hook 20 is moved while maintaining the parallel state it had before it moved. In this way, the movement of the eccentric 10 and the first hook 20 brings the weft thread 202-1 into a state where it is hooked on the first hook 20 and is positioned at the top of the eccentric 10.

As shown in FIG. 4, the first hook 20 advances by the sixth action of moving the first hook forward, and the weft thread 202-1 comes out of the hook 21, is lifted by the open latch 22, and falls on the rear of the latch 22 of the first hook 20, and the hook 21 approaches the hair thread 100 that is folded in half between the stocker 40 and the second hook 30. Then, the first hook 20 rotates by the seventh action of moving the first hook sideways, so that the needle mouth of the hook 21 faces sideways instead of upwards. With this rotation of the first hook 20, the needle mouth of the hook 21 faces the side that contacts the left side of the thread take-up hole 42 from the second hook 30 of the hair thread 100, that is, the back side of the paper in FIG. 4.

5, the first hook 20 advances further through the needle mouth of the hook 21 while remaining horizontal, as a result of the first hook advancement motion as the eighth motion, so that the hook 21 enters between the part of the hair thread 100 that contacts the left side of the thread take-up hole 42 from the second hook 30 and the part of the hair thread 100 that contacts the left side of the thread take-up hole 42 from the second hook 30, and the first hook 20 advances and stops until the needle mouth of the hook 21 faces the part of the hair thread 100 that contacts the left side of the thread take-up hole 42 from the second hook 30. After that, the second hook 30 moves horizontally from the back side to the front side of the paper in FIG. 5 as a ninth motion, so that the part of the hair thread 100 that contacts the left side of the thread take-up hole 42 from the second hook 30 is introduced into the needle mouth of the first hook 20 as shown in FIG. B. As a result, the first hook 20 captures the portion of the hair thread 100 that contacts the second hook 30 to the left of the thread take-up hole 42. Because the needle mouth of the hook 21 faces the upper side of Figure B and the needle mouth 32 of the hook 31 faces the lower side of Figure B, the hair thread 100 does not come off the second hook 30 when the hair thread 100 is introduced.

6, the first hook 20 rotates so that the mouth of the hook 21 faces upward from the side as the 10th operation, and the latch 22 comes into contact with the weft thread 202-1 to close the mouth. As the first hook 20 moves back to the initial position and away from the hair implant net 200 as shown by the solid line, the part of the hair thread 100 that contacts the left side of the thread take-up hole 42 from the second hook 30 is pulled out from the stocker 40. The pulled-out portion of the hair thread 100 passes from the left side of the thread take-up hole 42 through the thread positioning bar 50, between the weft threads 202-1 and 202-2, and is folded back by the hook 21, and then passes from the hook 21 between the weft threads 202-1 and 202-2, and further between the weft threads 202-1 and 202-3, and is deployed to reach the second hook 30. As the first hook 20 retreats from the position shown by the solid line to the position shown by the imaginary line, the latch 22 is attracted by the magnetic force of the magnet 90, and the needle mouth of the first hook 20 opens.

As shown in FIG. 7, the first hook 20 advances and ascends from the position shown by the imaginary line in FIG. 6 by the first hook ascending operation as the 11th operation, and the portion between the hook 21 of the hair yarn 100 and the weft yarn 202-1 assumes a V-shape with the weft yarn 202-1 at the center. The first hook ascending operation is not necessary, but by performing the first hook ascending operation, the hook 21 will reliably pass through the portion between the thread positioning bar 50 of the hair yarn 100 and the weft yarn 202-1 during the 12th operation described below. After that, the first hook 20 rotates to tie the hair yarn 100 to the weft yarn 202-1. The number of rotations of the first hook 20 may be one, two, or three or more rotations. As the first hook 20 rotates, the two parts of the hair yarn 100 between the hook 21 and the weft yarn 202-1 are twisted together to form a loop 45, and the hook 21 stops with the tip facing upward.

8, the first hook 20 moves upward toward the front side of the paper and then moves forward, and the hook 21 passes between the thread positioning bar 50 of the hair yarn 100 and the weft yarn 202-1. The first hook 20 moves forward until the needle mouth of the hook 21 contacts the right side of the thread take-up hole 42 of the hair yarn 100 from the second hook 30 of the hair yarn 100 and stops. At this time, the loop portion 45 falls onto the rear part of the latch 22 of the first hook 20. After that, the first hook 20 rotates so that the needle mouth of the hook 21 faces sideways from the upward position. With this rotation of the first hook 20, the needle mouth of the hook 21 faces the side that contacts the right side of the thread take-up hole 42 of the second hook 30 of the hair yarn 100, that is, the back side of the paper in FIG. 8. As the thirteenth operation, the second hook 30 moves laterally from the back side to the front side of the paper in Fig. 8, and the part of the hair thread 100 that contacts the right side of the thread hole 42 from the second hook 30 may be introduced into the needle mouth of the hook 21. Alternatively, the first hook 20 may move laterally from the front side to the back side of the paper in Fig. 8, and the part of the hair thread 100 that contacts the right side of the thread hole 42 from the second hook 30 may be introduced into the needle mouth of the hook 21. As a result, the first hook 20 captures the part of the hair thread 100 that contacts the right side of the thread hole 42 from the second hook 30, and the hair thread 100 is introduced into the first hook 20. Note that both the second hook 30 and the first hook 20 may move closer to each other. The needle mouth of the hook 21 faces the back side of the paper in FIG. 8, and the needle mouth 32 of the hook 31 of the second hook 30 faces the front side of the paper in FIG. 8, so the hair thread 100 will not come off the second hook 30 when it is introduced.

As shown in FIG. 9, the first hook 20, which has captured the part of the hair thread 100 that contacts the right side of the thread hole 42 from the second hook 30, rotates upward as the first hook 20 retracts to the initial position, and the latch 22 contacts the loop 45, the needle mouth of the hook 21 is closed, and the knotting of the hair thread 100 to the weft thread 202-1, i.e., the hair implantation, is completed. When the hook 21 of the first hook 20 retracts and passes through the loop 45, the second hook 30 moves up and down in small movements to remove the hair thread 100 from the hook 31 and prevent peeling of the hair thread 100. Peeling refers to the phenomenon in which the hair thread 100 shrinks due to friction.

As shown in FIG. 10, the thread retraction bar operation, which is the 15th operation, retracts the thread retraction bar 70 toward the initial position, and retracts the portion of the hair thread 100 on the side of the thread positioning bar 50 toward the eccentric 10. Then, the thread retraction bar 70 stops at the initial position.

As shown in FIG. 11, the 16th to 18th operations are performed. In the 16th operation, the first hook 20 returns to the initial position and stops while the latch 22 closes the needle mouth of the hook 21. In the 17th operation, the eccentric 10 rotates around the center line of the shaft 13 from the position shown by the solid line in FIG. 3 back to the position shown by the imaginary line in FIG. 3, and the opening of the escape portion 12 returns to the initial position facing left. In the 18th operation, the thread drop bar 60 moves downward, and the hair thread 100 that has been implanted into the weft thread 202-1 is arranged downward. Then, the thread drop bar 60 moves upward and stops at the initial position. This completes one cycle of the operation of implanting the hair thread 100 into the weft thread 202-1 in the hair implantation device, and the knot shown in FIG. 12 is created. FIG. 12 shows the state in which, in the 11th operation, the first hook 20 rotates three times and the hair-implanted yarn 100 is twisted three times and tied to the hair-implanted net 200. Any of the 16th to 18th operations may be performed first, or the 16th to 18th operations may be performed simultaneously.

In FIG. 1, the bottom 41 of the storage container 40 does not necessarily have to have a thread take-up hole 42, but by providing the thread take-up hole 42 in the bottom 41 as shown, the second hook 30 can be raised and lowered linearly for insertion and removal, making it easier for the second hook 30 to capture the hair thread 100 from the storage container 40.

In FIG. 1, the storage container 40 is configured in a trough shape with left and right side walls protruding upward from both left and right ends of the flat bottom so that the hair yarns 100 can be stored in a line along the extension of the center line of the eccentric 10, and the top is open, but as shown in the figure, the storage container 40 is configured in a trough shape with left and right side walls protruding upward from both left and right ends of the flat bottom so that the hair yarns 100 can be stored in a line along the extension of the center line of the eccentric 10, and the top is open, so that the hair yarns 100 can be easily stored in the storage container 40.

In FIG. 1, it is possible to apply the present invention even if the thread positioning bar 50 having the thread guide 51 that accommodates the hair thread 100 spread out between the second hook 30 and the stocker 40 is not provided below the stocker 40. However, if the thread positioning bar 50 having the thread guide 51 that accommodates the hair thread 100 spread out between the second hook 30 and the stocker 40 is provided below the stocker 40 as shown in the figure, the position of the hair thread 100 spread out between the second hook 30 and the stocker 40 will be secured in a predetermined position.

In FIG. 1, it is possible to apply the present invention even if the thread retraction bar 70 that moves back and forth to retract the hair thread 100 implanted in the hair implant net 200 is not provided between the eccentric 10 and the stocker 40. However, if the thread retraction bar 70 that moves back and forth to retract the hair thread 100 implanted in the hair implant net 200 is provided between the eccentric 10 and the stocker 40 as shown in the figure, the hair thread 100 implanted in the hair implant net 200 can be reliably retracted to the side of the first hook 20.

In FIG. 1, it is possible to apply the present invention even if the thread drop bar 60 that sweeps down the hair thread 100 pulled in by the thread pull-in bar 70 between the eccentric 10 and the stocker 40 and sets it downward is not provided. However, if the thread drop bar 60 that sweeps down the hair thread 100 pulled in by the thread pull-in bar 70 and sets it downward is provided between the eccentric 10 and the stocker 40 as shown in the figure, the hair thread 100 can be aligned on the side of the first hook 20, and the hair thread 100 implanted in the hair implant net 200 can be firmly tied.

The hair thread 100 of the present invention may be human hair or artificial hair made of synthetic fibers. It may also be a mixture of human hair and artificial hair.
