Mode for Carrying Out the Invention

[0008] The hair implanting device according to the mode for carrying out the invention shown in FIG. 1 includes an eccentric 10, a first crochet needle 20, a second crochet needle 30, a stocker 40, a thread position detecting bar 50, a thread dropping bar 60, a thread pulling bar 70, a reversing roller 80, a magnet 90 shown in FIG. 6, a drive mechanism (not shown), and a control device 95. Along with the control of the drive mechanism by the control device 95, the eccentric 10, the first crochet needle 20, the second crochet needle 30, the thread dropping bar 60, and the thread pulling bar 70 each perform the 1st to 18th operations shown in FIGS. 2 to 11, capture the hair yarns 100 one by one from the stocker 40, tie them to the horizontal threads 202 of the hair implanting net 200, and perform hair implantation. The hair implanting net 200 includes both the case where it is made using a single thread formed by twisting a plurality of raw yarns together and the case where it is made using a single raw yarn without twisting a plurality of raw yarns together.

[0009] When explaining the state of the initial position when the hair implanting device operates, as shown in FIG. 1A, a plurality of short hair threads 100 that have been pre-trimmed are laid and accommodated in a long row in a direction intersecting the extending direction of the center line of the eccentric 10 on a stocker 40 disposed above the eccentric 10. Further, a hair implanting net 200 formed in a mesh shape consisting of a plurality of vertical threads 201 and a plurality of horizontal threads 202 is deployed on the reversing roller 80 and the eccentric 10. Further, the first crochet hook 20 stops on the left side of the eccentric 10, the second crochet hook 30 stops below the right side of the eccentric 10, the thread positioning bar 50 is disposed below and to the left of a thread taking hole 42 provided at the center in the left-right direction of the bottom 41 of the stocker 40, and the thread dropping bar 60 and the thread pulling bar 70 stop to the left of the thread positioning bar 50 between the thread positioning bar 50 and the eccentric 10.

[0010] Incidentally, the length of the short hair thread 100 is trimmed to about twice the length of the hair of the completed wig, and it is applicable whether it is longer or shorter than the left-right direction of the bottom 41 of the stocker 40. However, when the protruding portion of the hair thread 100 outside the bottom 41 of the stocker 40 does not vertically hang down below the bottom 41 of the stocker 40, when the second crochet hook 30 captures the hair thread 100 from the stocker 40 and pulls it downward, it is possible to prevent the protruding portion of the hair thread 100 outside the bottom 41 of the stocker 40 from rubbing and being damaged at the left-right ends of the bottom 41 of the stocker 40, which is preferable.

[0011] As shown in FIG. 1B, the stocker 40 includes left and right side walls 43 protruding upward from both ends in the left-right direction of a flat bottom 41, and the upper portions of the left and right side walls 43 are in a gutter shape with an open top. Although a single stocker 40 is applicable, a plurality of stockers 40 are arranged in the left-right direction, and different types of hair threads 100 are mixed, such as hair threads 100 of different colors, hair threads 100 of the same color but different thicknesses, and hair threads 100 of the same color and the same thickness but different hardness (elasticity), and then each stocker 40 is supplied individually. The case where the color, thickness, or hair quality of the hair thread 100 in the completed wig can be adjusted in advance is illustrated.

[0012] Furthermore, the stocker 40 is provided in a fixed state to a device main body (not shown) that does not need to move its position. A plate-shaped weight (not shown) is placed on the hair thread 100 supplied to the stocker 40 to press the hair thread 100, so that the hair thread 100 can be pulled out by the second crochet hook 30. The weight may press the hair thread 100 from above by the expansion and contraction of the piston rod of an air cylinder as a drive mechanism connected to both the device main body and the weight. The expansion and contraction of the piston rod of the air cylinder may be controlled by the control device 95.

[0013] Then, when the second crochet hook 30 pulls out several hair threads 100, the hook 31 at the tip of the second crochet hook 30 no longer catches the hair thread 100. Therefore, each time several hair threads 100 are pulled out, the pressure supplied from the weight to the hair thread 100 is loosened, the stocker 40 is tapped, and the hair thread 100 can be realigned. The time interval until the pressure is loosened and realigned varies depending on the type of the hair thread 100. When tapping the stocker 40, although it is conceivable to do it manually, it may also be done by a drive mechanism controlled by the control device 95.

[0014] The eccentric 10 is a member for securing the hair implanting area of the hair implanting net 200, and has a columnar net hanging part 11 having a center line extending left and right, a relief part 12 provided on the net hanging part 11 so as to be recessed from the outer surface of the net hanging part 11 to the inside, and shaft parts 13 provided at both ends of the net hanging part 11. The center line extending in the left-right direction of the shaft part 13 is offset radially outward from the center line extending in the left-right direction 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 relief part 12.

[0015] Then, the shaft part 13 is rotatably supported by a bearing part (not shown) provided on a device main body (not shown), and the eccentric 10 is stopped so that the opening of the relief part 12 faces left as shown in FIG. 1A. Also, the center line extending in the left-right direction of the shaft part 13 overlaps a single weft thread 202-1 located at the circumferential center of the opening of the relief part 12.

[0016] The opening width corresponding to the circumferential direction of the net hanging portion 11 in the escape portion 12 is determined based on the interval between the horizontal yarns 202 that form the mesh of the flocked net 200 such that when the flocked net 200 is wound around the outer surface of the net hanging portion 11 and one horizontal yarn 202-1 is located at the center in the circumferential direction of the opening width of the escape portion 12, one of the two horizontal yarns 202-2 and 202-3 adjacent to the one horizontal yarn 202-1 located at the center is located around one side edge of the opening of the escape portion 12, and the other one of the two horizontal yarns 202-2 and 202-3 is located around the other side edge of the opening of the escape portion 12. Incidentally, the opening width corresponding to the circumferential direction of the net hanging portion 11 in the escape portion 12 may be equal to or greater than the width between the horizontal yarn 202-2 and the horizontal yarn 202-3.

[0017] The first crochet hook 20 is a member for implanting the hair yarn 100 into the flocked net 200, and includes 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 crochet hook 20 by a shaft (not shown in the figure), and the other end side of the latch 22 rotates around the shaft to open and close the needle opening. In the initial state, as shown in FIG. 1A, the first crochet hook 20 stops at a position away from the eccentric 10 to the left and facing the opening of the escape portion 12, and the latch 22 closes the needle opening.

[0018] The first crochet hook 20 operates by a drive mechanism controlled by the control device 95 to implant the hair yarn 100. Also, the first crochet hook 20 is arranged in a plurality of rows side by side, similar to the plurality of second crochet hooks 30 shown in FIG. 1B. A group of the plurality of first crochet hooks 20 operates together by a drive mechanism controlled by the control device to implant the hair yarn 100 into the flocked net 200. The first crochet hook 20 and the second crochet hook 30 are associated one-to-one. The first crochet hook 20 and the second crochet hook 30 are not limited to a plurality and may be a single one.

[0019] The second crochet hook 30 is a member that captures the hair yarn 100 from the stocker 40, and a hook 31 capable of capturing one hair yarn 100 is provided at the tip. In the initial state, as shown in FIG. 1A, the second crochet hook 30 is separated from the eccentric 10 to the right and stops at a position between the eccentric 10 and the reversing roller 80, and the needle opening 32 of the hook 31 faces the front side of the paper surface in FIG. 1A. Also, as shown in FIG. 1B, the second crochet hooks 30 are arranged in a plurality of rows side by side. A group of a plurality of second crochet hooks 30 operates together by a drive mechanism controlled by the control device 95 to capture the hair yarn 100. Here, the case where the hook 31 captures one hair yarn 100 is exemplified, but the hook 31 may be configured to capture two or more hair yarns 100.

[0020] The yarn positioning bar 50 is a member that guides the hair yarn 100 drawn from the stocker 40 by the second crochet hook 30 to a predetermined position. As shown in FIG. 1B, a plurality of yarn guides 51 that are recessed from the columnar outer peripheral surface having a center line extending in the left and right directions toward the center line are provided so as to go around the columnar outer peripheral surface. Also, both left and right ends of the yarn positioning bar 50 in the left - right direction may be fixedly provided on the apparatus main body, but it is preferably rotatably provided, so that the yarn positioning bar 50 is rotated by the hair yarn 100 drawn from the stocker 40 by the second crochet hook 30, and the portion of the hair yarn 100 drawn by the second crochet hook 30 can be prevented from being rubbed and damaged by the yarn guide 51, which is preferable. The number of the yarn guides 51 is the same as the number of the second crochet hooks 30.

[0021] The yarn dropping bar 60 vibrates up and down by a drive mechanism controlled by the control device 95 in the process where the hair yarn 100 implanted in the implanting net 200 is drawn in by the yarn drawing bar 70, and sweeps off the end of the hair yarn 100 drawn in by the yarn drawing bar 70 to groom the hair yarn 100 downward.

[0022] The thread drawing bar 70 moves back and forth by a drive mechanism controlled by the control device 95 and is adapted to draw in the hair threads 100 implanted in the hair implanting net 200. The magnet 90 is used in the pre-process of implanting the hair threads 100 into the hair implanting net 200 with the first crochet hook 20. When the first crochet hook 20 enters between the two-folded hair threads 100 formed by the second crochet hook 30 and the stocker 40 and then retreats, the latch 22 of the first crochet hook 20 touches the hair threads 100 and closes. Therefore, the magnet 90 is attached to the apparatus main body so as to attract and open the closed latch 22 by magnetic force. Either a permanent magnet or an electromagnet can be applied. However, in the case of an electromagnet, the electromagnet can generate magnetic force only when the control device 95 controls the electromagnet to open the closed latch 22. The reversing roller 80 is attached to the apparatus main body.

[0023] The operation of the hair implanting device will be described with reference to FIGS. 2 to 11. As shown in FIG. 2, by the forward movement of the thread drawing bar as the first operation, the front portion of the thread drawing bar 70 moves forward and stops at a position beyond the thread taking hole 42 of the stocker 40 and the second crochet hook 30 in FIG. B. Next, by the upward movement of the second crochet hook as the second operation, the second crochet hook 30 rises, and after the hook 31 enters the rows of a plurality of hair threads 100 inside the stocker 40 via the thread taking hole 42, it descends and stops at the initial position. By descending and stopping while the hook 31 catches the central portion in the left-right direction of one hair thread 100 in this upward movement of the second crochet hook, the above one hair thread 100 is in a state of being folded in two between the stocker 40 and the second crochet hook 30. As shown in FIG. B of FIG. 2, since the hair threads 100 folded in two by the plurality of second crochet hooks 30 are respectively accommodated in the plurality of thread guides 51 of the thread positioning bar 50 one by one, the positions of the respective hair threads 100 developed between the second crochet hook 30 and the stocker 40 are secured at predetermined positions, and the first crochet hook 20 can appropriately capture each hair thread 100.

[0024] Also, as the first crochet forward movement as the third movement, as the hook 21 of the first crochet 20 passes under the weft thread 202-1, the latch 22 interferes with the weft thread 202-1 and opens, and the needle opening of the hook 21 escapes beyond the weft thread 202-1 from the left side to the right side and reaches the position shown by the virtual line and is accommodated in the escape portion 12. Then, by the first crochet backward movement as the fourth movement, the first crochet 20 retreats from the position shown by the virtual line to the position shown by the solid line, and the hook 21 catches the weft thread 202-1.

[0025] As shown in FIG. 3, as the fifth movement, by the eccentric 1 / 4 rotation movement, as the shaft portion 13 of the eccentric 10 is rotated in one direction by a drive mechanism (not shown), the net hanging portion 11 pivots downward from the position shown by the virtual line around the center line of the shaft portion 13 to the position shown by the solid line, and the opening of the escape portion 12 is directed upward, and the rotation of the shaft portion 13 in one direction stops. As a result, the eccentric 10 moves below the first crochet 20 and the weft thread 202-1 without moving the first crochet 20 and the weft thread 202-1. The phrase "without moving the first crochet 20 and the weft thread 202-1" includes the case where the tip portion of the first crochet 20 vibrates due to the elasticity of the planting net 200 when the eccentric 10 moves downward. By the movement of the eccentric 10 from the position shown by the virtual line to the position shown by the solid line, the first crochet 20 can move above the eccentric 10 and to the side between the two-folded hair yarns 100 between the stocker 40 and the second crochet 30. By pivoting the eccentric 10 downward from the position shown by the virtual line to a position below the first crochet 20, the weft thread 202-1 is not overloaded and does not break, and the first crochet 20 is not overloaded and does not break.

[0026] Further, without pivoting the eccentric 10 downward from the position indicated by the phantom line to the position indicated by the solid line, while the first crochet hook 20 holds the cross yarn 202-1, the eccentric 10 is rotated about the center line of the net hanging portion 11 by a drive mechanism (not shown) under the control of the control device 95 and the first crochet hook 20 is moved along the movement of the cross yarn 202-1 supplemented by the first crochet hook 20. At this time, the first crochet hook 20 is moved while maintaining the parallel state before the movement. Thus, due to the movements of the eccentric 10 and the first crochet hook 20, the cross yarn 202-1 is in a state of being hooked by the first crochet hook 20 and located at the uppermost position of the eccentric 10.

[0027] As shown in FIG. 4, in the first crochet hook forward movement as the sixth operation, as the first crochet hook 20 moves forward, the cross yarn 202-1 comes out of the hook 21 and is lifted by the opened latch 22 and drops above the latch 22 of the first crochet hook 20 at the rear, and the hook 21 approaches the side of the hair yarn 100 folded in two between the stocker 40 and the second crochet hook 30. Then, in the first crochet hook lateral movement as the seventh operation, the first crochet hook 20 rotates so that the needle opening of the hook 21 changes from the upward-facing state to the lateral-facing state. Along with the rotation of the first crochet hook 20, the needle opening of the hook 21 is directed to the side that contacts the hair yarn 100 from the left side of the yarn taking hole 42 of the second crochet hook 30, that is, the state facing the back side of the paper surface of FIG. 4.

[0028] As shown in Fig. 5, with the first crochet forward movement as the eighth operation, as the first crochet 20 further advances while keeping the needle opening of the hook 21 sideways, the hook 21 enters between the portion contacting the left side of the thread take-up hole 42 from the second crochet 30 of the hair thread 100 and the portion contacting the left side of the thread take-up hole 42 from the second crochet 30, and the first crochet 20 advances and stops until the needle opening of the hook 21 faces the portion contacting the left side of the thread take-up hole 42 from the second crochet 30 of the hair thread 100. Then, with the second crochet lateral movement as the ninth operation, as the second crochet 30 laterally moves from the back side to the front side of the paper surface of Fig. 5, as shown in Fig. B, the portion contacting the left side of the thread take-up hole 42 from the second crochet 30 of the hair thread 100 is introduced into the needle opening of the first crochet 20. Thereby, the first crochet 20 captures the portion contacting the left side of the thread take-up hole 42 from the second crochet 30 of the hair thread 100. Since the needle opening of the hook 21 is directed upward and the needle opening 32 of the hook 31 is directed downward in Fig. B, the hair thread 100 does not come off from the second crochet 30 when the hair thread 100 is introduced.

[0029] As shown in Fig. 6, with the first crochet backward movement as the tenth operation, the first crochet 20 rotates so that the needle opening of the hook 21 turns upward from the sideways state, the latch 22 contacts the cross yarn 202-1 and the needle opening is closed. As the first crochet 20 retreats to the side of the initial position and moves away from the hair implanting net 200 as shown by the solid line, the portion contacting the left side of the thread take-up hole 42 from the second crochet 30 of the hair thread 100 is pulled out from the stocker 40. The pulled-out portion of this hair thread 100 passes between the cross yarn 202-1 and the cross yarn 202-2 via the thread positioning bar 50 from the left side of the thread take-up hole 42, is folded back by the hook 21, and then passes between the cross yarn 202-1 and the cross yarn 202-2 from the hook 21, and further unfolds so as to reach the second crochet 30 passing between the cross yarn 202-1 and the cross yarn 202-3. As the first crochet 20 retreats from the position shown by the solid line to the position shown by the virtual line, the latch 22 is attracted by the magnetic force of the magnet 90 to open the needle opening of the first crochet 20.

[0030] As shown in FIG. 7, as the first crochet upward movement as the 11th operation, as the first crochet 20 moves forward and upward from the position shown by the virtual line in FIG. 6, the portion between the hook 21 of the hair yarn 100 and the weft 202-1 assumes a V shape centered on the weft 202-1. Note that the first crochet upward movement may not be performed, but by performing the first crochet upward movement, when the 12th operation described later is performed, the hook 21 can surely pass through the portion between the yarn positioning bar 50 of the hair yarn 100 and the weft 202-1. Thereafter, the first crochet 20 rotates to tie the hair yarn 100 to the weft 202-1. The number of rotations of the first crochet 20 may be one rotation, two rotations, or three or more rotations. When the first crochet 20 rotates, the two portions between the hook 21 of the hair yarn 100 and the weft 202-1 are twisted so as to be intertwined with each other, and the loop portion 45 is provided and stops with the needle hole of the hook 21 facing upward.

[0031] As shown in FIG. 8, by the first crochet forward and lateral movement as the twelfth operation, after the first crochet 20 moves to the front side of the paper surface while facing upward and then moves forward, the hook 21 passes through the portion between the thread positioning bar 50 of the hair thread 100 and the weft thread 202-1, and the first crochet 20 moves forward and stops until the needle opening of the hook 21 contacts the portion on the right side of the thread taking hole 42 from the second crochet 30 of the hair thread 100. At this time, the loop portion 45 is in a state of falling above the latch 22 of the first crochet 20. Then, the first crochet 20 rotates so that the needle opening of the hook 21 turns laterally from the state where it faces upward. Along with the rotation of the first crochet 20, the needle opening of the hook 21 is directed toward the side that contacts the portion on the right side of the thread taking hole 42 from the second crochet 30 of the hair thread 100, that is, the back side of the paper surface of FIG. 8. As the thirteenth operation, the second crochet 30 laterally moves from the back side to the front side of the paper surface of FIG. 8 and introduces the portion that contacts the portion on the right side of the thread taking hole 42 from the second crochet 30 of the hair thread 100 into the needle opening of the hook 21. Or, the first crochet 20 may laterally move from the front side to the back side of the paper surface of FIG. 8 and introduce the portion that contacts the portion on the right side of the thread taking hole 42 from the second crochet 30 of the hair thread 100 into the needle opening of the hook 21. Thereby, the first crochet 20 captures the portion that contacts the portion on the right side of the thread taking hole 42 from the second crochet 30 of the hair thread 100, and the hair thread 100 is introduced into the first crochet 20. Incidentally, both the second crochet 30 and the first crochet 20 may move so as to approach each other. Since the needle opening of the hook 21 is directed toward the back side of the paper surface of FIG. 8 and the needle opening 32 of the hook 31 of the second crochet 30 is directed toward the front side of the paper surface of FIG. 8, the hair thread 100 does not come off from the second crochet 30 when the hair thread 100 is introduced.

[0032] As shown in FIG. 9, by the first crochet hook retraction and rotation operation as the fourteenth operation, the first crochet hook 20 that captures the portion of the hair yarn 100 that contacts the right side of the yarn take-up hole 42 from the second crochet hook 30 rotates upward. As it retracts to the side of the initial position, the latch 22 contacts the loop portion 45, the needle opening of the hook 21 is closed, and the tying and implanting of the hair yarn 100 to the weft yarn 202-1 is completed. When the hook 21 of the first crochet hook 20 retracts and passes through the loop portion 45, the second crochet hook 30 moves up and down in small increments to prevent peeling of the hair yarn 100 that is removed from the hook 31. Peeling refers to the phenomenon in which the hair yarn 100 shrinks due to friction.

[0033] As shown in FIG. 10, by the weft yarn drawing bar retraction operation as the fifteenth operation, as the weft yarn drawing bar 70 retracts to the side of the initial position, the portion of the hair yarn 100 on the side of the yarn positioning bar 50 is drawn toward the eccentric 10. Then, the weft yarn drawing bar 70 stops at the initial position.

[0034] As shown in FIG. 11, the sixteenth to eighteenth operations are performed. During the sixteenth operation when the first crochet hook 20 returns to the initial position and stops, the latch 22 closes the needle opening of the hook 21. During the seventeenth operation, as the eccentric 10 pivots back from the position shown by the solid line in FIG. 3 to the position shown by the virtual line in FIG. 3 about the center line of the shaft portion 13, the opening of the relief portion 12 returns to the initial position directed to the left side. During the eighteenth operation, as the yarn dropping bar 60 moves downward, the hair yarn 100 that has been implanted on the weft yarn 202-1 is groomed downward. Then, the yarn dropping bar 60 moves upward and stops at the initial position. Thereby, one cycle of the operation of implanting the hair yarn 100 on the weft yarn 202-1 in the implanting device is completed, and a knot is created as shown in FIG. 12. Note that FIG. 12 illustrates the state in which, in the eleventh operation, the first crochet hook 20 rotates three times, the implanting yarn 100 is twisted three times, and is tied to the implanting net 200. Note that any of the sixteenth to eighteenth operations may be performed first, or the sixteenth to eighteenth operations may be performed simultaneously.

[0035] In FIG. 1, it is applicable even if the thread take-out hole 42 is not provided at the bottom 41 of the stocker 40. However, as shown in the figure, since the thread take-out hole 42 is provided at the bottom 41, the second crochet hook 30 can move up and down linearly to enable insertion and extraction, so that the operation of capturing the hair thread 100 from the stocker 40 by the second crochet hook 30 becomes simple.

[0036] In FIG. 1, the stocker 40 is applicable in other configurations than being formed in a trough shape with an open top, having left and right side walls protruding upward from both left and right ends in the horizontal direction of a flat bottom so that the hair threads 100 are arranged and accommodated in the direction of the extension of the center line of the eccentric 10. However, as shown in the figure, since the stocker 40 is formed in a trough shape with an open top, having left and right side walls protruding upward from both left and right ends in the horizontal direction of a flat bottom so that the hair threads 100 are arranged and accommodated in the direction of the extension of the center line of the eccentric 10, the hair threads 100 can be easily accommodated in the stocker 40.

[0037] In FIG. 1, it is applicable even if the thread positioning bar 50 having the thread guide 51 for accommodating the hair thread 100 deployed between the second crochet 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 for accommodating the hair thread 100 deployed between the second crochet hook 30 and the stocker 40 is provided below the stocker 40 as shown in the figure, the position of the hair thread 100 deployed between the second crochet hook 30 and the stocker 40 is secured at a predetermined position.

[0038] In FIG. 1, it is applicable even if the thread pulling bar 70 that moves back and forth to pull in the hair thread 100 implanted in the hair implanting net 200 is not provided between the eccentric 10 and the stocker 40. However, if the thread pulling bar 70 that moves back and forth to pull in the hair thread 100 implanted in the hair implanting 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 implanting net 200 can be surely pulled to the side of the first crochet hook 20.

[0039] In Fig. 1, it is applicable even if there is no yarn dropping bar 60 that drops the hair yarn 100 drawn in by the yarn drawing bar 70 between the gripper 10 and the stocker 40 and arranges it downward. However, if there is a yarn dropping bar 60 that drops the hair yarn 100 drawn in by the yarn drawing bar 70 between the gripper 10 and the stocker 40 as shown in the figure, the hair yarn 100 can be aligned on the side of the first crochet needle 20, and there is an effect that the hair yarn 100 planted on the implant net 200 is firmly bound.

[0040] The hair yarn 100 of the present invention may be human hair or artificial hair made of synthetic fiber. Also, it may be a mixture of human hair and artificial hair.

[0041] In addition, depending on the wig to be completed, there may be a case where the hair yarn 100 is not bound to a part of the implant net 200 without binding the hair yarn 100 to all of the weft yarns 202 of the implant net 200. In that case, it is also possible to prevent the hair yarn 100 from being bound to the implant net 200 by not capturing the hair yarn 100 from the stocker 40 by controlling the control device 95 not to perform the second crochet needle rising operation as the second operation.
