Abstract

The present invention provides a hair implantation device that can stably implant hair material onto a hair implantation net compared to conventional devices. [Solution] The hair implantation net comprises a net transport section, a hair material supply section, a hair implantation needle section, and a first restricting section that restricts the movement of the hair material. The hair implantation net has a first hole section and a second hole section adjacent to each other with a net thread in between. The hair implantation operation can be performed including an annular section forming operation in which the middle portion of the hair material is passed through the first hole section and the second hole section of the hair implantation net to form an annular section, and a hair material passing operation in which the hair implantation needle section is engaged with one end of the hair material beyond the annular section, and the hair material is moved so that the engaged portion of the hair material with the hair implantation needle section passes through the annular section. In the hair material passing operation, after the engaged portion has passed through the annular section, the movement of the portion between the engaged portion and the annular section is restricted by the first restricting section, and the hair implantation needle section is further moved to allow one end of the hair material to pass through the annular section.

Description

Technical Field

[0001] The present invention relates to a hair implanting device for implanting hair materials onto a hair implanting net.

Background Art

[0002] Conventionally, a hair implanting device for binding a hair material for hair implantation to a hair implanting net has been known (for example, Patent Document 1). In the hair implanting device of Patent Document 1, a first crochet hook is hooked on the weft of the hair implanting net supported by an eccentric, and the hooked portion is inserted through the space between adjacent holes sandwiching the weft of the hair implanting net to form a loop portion. Then, in the hair implanting device of Patent Document 1, with the first crochet hook as a reference, after hooking the first crochet hook on the yarn on the distal side of the hair material, in a state where the hair material can move freely from the stocker, the hooked yarn on the distal side is passed through the loop portion and pulled out, so that it is possible to implant hair onto the hair implanting net.

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the hair implanting device of Patent Document 1, in order to tighten the loop portion with the first crochet hook while passing the yarn through the loop portion, before the yarn completely passes through the loop portion, the loop portion is constricted and becomes smaller, and there is a case where the yarn cannot pass through the loop portion halfway. Therefore, there was room for further improvement.

[0005] Therefore, an object of the present invention is to provide a hair implanting device that can stably implant hair materials onto a hair implanting net as compared with the prior art.

Means for Solving the Problems

[0006] One aspect of the present invention for solving the above-mentioned problems includes a net transport unit for transporting a hair implantation net, a hair material supply unit for supplying hair material from the middle portion toward the hair implantation net, a hair implantation needle unit for attaching a portion of the middle portion of the hair material supplied from the hair material supply unit to the hair implantation net and implanting hair, and a first restricting unit for restricting the movement of the hair material, wherein the hair implantation net has a first hole portion and a second hole portion adjacent to each other with a net thread in between, and the middle portion of the hair material passes through the first hole portion and the second hole portion of the hair implantation net. The hair implantation device is capable of performing a hair implantation operation that includes an annular portion forming operation and a hair material passing operation in which the hair implantation needle portion is engaged with the hair material on one end side of the annular portion and the hair material is moved so that the engaged portion of the hair material with the hair implantation needle portion passes through the annular portion, wherein in the hair material passing operation, after the engaged portion has passed through the annular portion, the movement of the portion between the engaged portion and the annular portion is restricted by the first restricting portion, and the hair implantation needle portion is further moved to allow one end side of the hair material to pass through the annular portion.

[0007] According to this configuration, during the hair material passage operation, after the portion of the hair material that engages with the hair implanting needle passes through the annular portion, the movement of the portion of the hair material between the engaging portion and the annular portion is restricted by the first restricting portion, and one end of the hair material is then allowed to pass through the annular portion. This prevents the annular portion from becoming smaller as the hair implanting needle moves, and allows the entire hair material, including one end, to pass through the annular portion as the hair implanting needle moves. As a result, the middle of the hair material is hardly constricted by the annular portion, and the hair material can be implanted into the hair implantation net more stably than in the conventional method.

[0008] By the way, in the hair implantation device described in Patent Document 1, when the loop portion is tightened by the movement of the first hook, the hook portion of the first hook is only caught on the thread. Therefore, once the loop portion is tightened to a certain extent, the resistance between the middle of the thread and the loop portion increases, causing the thread to slip at the hook portion, and in some cases the loop portion cannot be tightened any further. As a result, it is not possible to firmly tighten the ring portion and form a knot, the loop portion is noticeable, and there is a problem that the hair material tends to fall out of the hair implantation net.

[0009] A preferred configuration is one in which the first restricting portion restricts the movement of the hair material by gripping it, and the hair implantation operation includes a tightening operation in which the first restricting portion, which is gripping the hair material, is moved after the hair material has passed through, such that the annular portion becomes smaller.

[0010] According to this design, the ring portion is tightened to become smaller after the hair material passes through, allowing for a more secure tightening of the ring portion compared to conventional designs. As a result, the knots caused by the ring portion can be made smaller and less noticeable compared to conventional designs, and the hair material is less likely to fall out of the hair implantation net.

[0011] A preferred configuration is one in which the first restricting portion restricts the movement of the hair material by gripping it, and during the hair material passage operation, after the engagement portion of the hair material with the hair implanting needle portion has passed through the annular portion, the portion between the engagement portion and the annular portion is gripped by the first restricting portion, and the first restricting portion, while gripping the hair material together with the hair implanting needle portion, is moved to allow one end of the hair material to pass through the annular portion.

[0012] A preferred configuration includes a second restricting portion capable of restricting the movement of the hair material at the other end than the annular portion.

[0013] The aspects described above can be dependent on each other, refer to some of their components, or substitute for some of their components, as long as they fall within the technical scope of the present invention. [Effects of the Invention]

[0014] According to the present invention, hair material can be implanted onto the hair implantation net more stably than in the conventional method. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0016] Embodiments of the present invention will be described in detail below.

[0017] The hair implantation device 1 of the first embodiment of the present invention is an automatic hair implantation device that automatically implants hair material 101 onto a hair implantation net 100. As shown in Figure 1, the hair implantation device 1 comprises an eccentric section (hereinafter also simply referred to as the eccentric section 2), a hair implantation hook section 3 (hair implantation hook section), a hair extraction hook section 5, a hair material supply section 6, a guide roll 7, a hair material pull-in section 8, a hair material drop-in section 10, a transport roll 11 (net transport section), a first regulating section 12, and a second regulating section 13.

[0018] (Excentric part 2) As shown in Fig. 1(b), the eccentric part 2 is an elongated body extending in the axial direction (width direction Z of the hair implanting net 100), and includes a main body part 20 and rotary shaft parts 21a and 21b. The eccentric part 2 is a rotary force conversion member in which the rotary shaft parts 21a and 21b are displaced with respect to the central axis of the main body part 20 and convert rotary motion into single vibration, and is a support roll for supporting the hair implanting net 100.

[0019] As shown in Fig. 2, the main body part 20 is a columnar part extending in the width direction Z, and includes a concave part 22 in which a part of the outer periphery is recessed. The concave part 22 is a notch groove into which a part of the hair implanting crochet part 3 can be inserted, and is a concave groove formed over the entire extending direction (width direction Z) of the main body part 20.

[0020] The rotary shaft parts 21a and 21b are shaft parts that serve as the rotation center of the eccentric part 2. The rotary shaft parts 21a and 21b extend outward from both ends of the main body part 20 in the width direction Z, and are provided at positions where the central axis is displaced from the central axis of the main body part 20 when viewed from the axial direction.

[0021] The eccentric part 2 can change its posture between the first posture and the second posture by rotating about the rotary shaft parts 21a and 21b. The first posture is an opposing posture in which the concave part 22 of the main body part 20 is located on the side of the hair implanting crochet part 3 and faces the hair implanting crochet part 3 as shown in Fig. 3(a). The second posture is a vertical posture in which the concave part 22 of the main body part 20 is located on the side of the hair material supply part 6 and faces upward as shown in Fig. 3(b).

[0022] (Hair implanting crochet part 3) The hair implanting crochet part 3 is a hair implanting needle part for implanting the hair material 101 into the hair implanting net 100, and the tip is a rod-shaped body with a hooked claw. As shown in Fig. 1, the hair implanting crochet part 3 is a latch hook needle including a needle shaft part 30, a hook part 31, and a latch part 32.

[0023] (Pull-out crochet part 5) The pull-out hook section 5 is a hook that pulls out the hair material 101 from the hair material supply section 6. The pull-out hook portion 5 is a rod-shaped body with a claw-shaped tip, and as shown in Figure 1, it comprises a needle shaft portion 40 and a hook portion 41.

[0024] (Hair material supply section 6) The hair material supply unit 6 is a hair material storage unit that houses the hair material 101 to be implanted into the hair implantation net 100, and is a so-called stocker. As shown in Figure 1, the hair material supply unit 6 is provided with an outlet hole 60 for taking out and supplying the hair material 101 which is housed inside and placed on the bottom 61. The removal hole 60 is a through-hole that penetrates the bottom plate portion constituting the bottom portion 61 in the thickness direction.

[0025] (Guidance Roll 7) As shown in Figure 1(b), the guide roll 7 has a groove 70 on a part of its outer surface, and a portion of the hair material 101 drawn out from the hair material supply unit 6 by the pull-out hook part 5 passes through the groove 70, thereby adjusting the position of the hair material 101 in the width direction Z to fall within a predetermined range.

[0026] (Hair material intake section 8) The hair material pull-in section 8 is a pull-in bar that pulls the hair material 101, which has been pulled out from the hair material supply section 6 by the pull-out hook section 5, to the downstream side in the transport direction T from the hair implantation position of the hair implantation net 100.

[0027] (Hair material insertion section 10) The hair material drop-in section 10 is a drop-in bar that drops the hair material 101, which has been pulled out from the hair material supply section 6 by the pull-out hook section 5, to a position below the hair implantation position on the hair implantation net 100.

[0028] (Conveyor roll 11) The conveying roll 11 is a support roll that supports the flocked net 100 so that it passes over the eccentric section 2, and is a net conveying section that conveys the flocked net 100 in the conveying direction T by rotating.

[0029] (First Regulatory Section 12) As shown in Figure 2, the first restricting section 12 has a first clamping section 80 and a second clamping section 81, and restricts the movement of the hair material 101 by clamping a part of the hair material 101 with the first clamping section 80 and the second clamping section 81. The first restricting section 12 is movable with at least a component in the front-to-back direction X, and by moving while gripping the hair material 101, it is possible to pull the hair material 101 away from the hair implantation net 100.

[0030] (Second Regulatory Section 13) As shown in Figure 1(b), the second restricting section 13 comprises a first clamping section 90 and a second clamping section 91, and restricts the movement of the hair material 101 by clamping a portion of the hair material 101 with the first clamping section 90 and the second clamping section 91.

[0031] (Hair transplant net 100) As shown in Figure 2, the flocked net 100 is a stretchable net constructed in a mesh-like manner by multiple netting threads 121, and has multiple holes 120. The flocked net 100 of this embodiment has a honeycomb structure and is expandable and contractible in the transport direction T and the width direction Z. The hole 120 is a hexagonal hole when viewed from above, with each side made up of netting yarn 121, and the two sides facing the transport direction T on either side of the hole 120 are made up of netting yarns 121a and 121b (weft yarns).

[0032] (Hair material 101) The hair material 101 is a thread-like structure that is implanted onto the hair implantation net 100. Hair material 101 can be artificial hair made of resin fibers, human hair, animal hair, etc. The hair material 101 of this embodiment is bundled together in multiple pieces and used as a hair bundle.

[0033] Next, the positional relationships of each part of the hair implantation device 1 of this embodiment will be described. Regarding the eccentric section 2, the description will be based on the first posture, in which the recess 22 of the main body section 20 shown in Figure 1 is located on the hair implantation hook section 3 side and faces the hair implantation hook section 3 side.

[0034] As shown in Figure 1, the hair flocking device 1 has a hair flocking net 100 suspended from an eccentric section 2 and a transport roll 11. The eccentric section 2 has rotating shafts 21a and 21b pivotally supported, and is capable of rotating in the circumferential direction around the rotating shafts 21a and 21b.

[0035] As shown in Figure 1, the flocked hook portion 3 is in a horizontal position extending horizontally, and the hook portion 31 faces the recess 22 of the main body portion 20 in the front-rear direction X. The pull-out hook section 5 has its tip hook section 41 positioned upwards and is in a vertical position extending in the vertical direction, facing the outlet hole 60 of the hair material supply section 6 in the height direction Y (up and down direction). The hair material intake section 8 is located below the hair material supply section 6 and above the eccentric section 2 in the height direction Y. The first restricting section 12 is positioned closer to the flocked hook section 3 than to the eccentric section 2. The second regulating section 13 is located near the outlet hole 60 of the hair material supply section 6 and is movable parallel to the bottom section 61.

[0036] Next, the hair implantation operation of the hair implantation device 1 of this embodiment will be described.

[0037] In this embodiment, the hair implantation operation first involves raising the pull-out hook portion 5 as shown in Figure 3(a) to hook the hook portion 41 onto the hair material 101 within the hair material supply portion 6, then lowering it back to its original reference position to pull out the middle portion of the hair material 101 within the hair material supply portion 6 through the extraction hole 60, and shifting the pull-out hook portion 5 in the width direction Z from the reference position (hair material pull-out operation).

[0038] At this time, the hair material 101 in the hair material supply section 6 is pulled out in a "V" shape by the hook portion 41 of the pull-out hook section 5, as shown in Figure 3(a), and the engagement portion (hooking portion) with the hook portion 41 of the pull-out hook section 5 is lower than the apex of the eccentric section 2. In addition, the hair material 101 is divided into a proximal hair portion 110 and a distal hair portion 111 based on the engagement portion (folded portion) with the hook portion 41 of the pull-out hook section 5.

[0039] In addition to the hair material pulling operation, as shown by the arrow in Figure 3(a), the hair flocking hook part 3 is advanced toward the eccentric part 2, and the hook part 31 of the hair flocking hook part 3 is passed through the hole 120a of the hair flocking net 100 on the eccentric part 2 and positioned within the recess 22 of the eccentric part 2. Then, the hair flocking hook part 3 is retracted from within the recess 22 of the eccentric part 2 and raised (net hooking operation).

[0040] At this time, the flocked hook portion 3 retracts and rises, hooking the netting threads 121 that make up the edge of the hole portion 120a of the flocked net 100 on the eccentric portion 2 with the hook portion 31 and lifting them upward. In other words, the flocked hook portion 3 hooks the netting threads 121 that extend in a direction intersecting the transport direction T (orthogonal in this embodiment) with the hook portion 31.

[0041] Next, with the flocked hook portion 3 hooked onto the netting thread 121, the eccentric portion 2 is rotated 90 degrees in the forward direction R1 as shown by the arrow in Figure 3(b) to the second position, and the hook portion 31 of the flocked hook portion 3 is brought out from inside the recess 22 (eccentric rotation operation).

[0042] At this time, as the eccentric part 2 rotates, the flocked hook part 3 is inserted across the adjacent holes 120a and 120b, with the netting threads 121 of the flocked net 100 in between.

[0043] Next, as shown in Figure 4(a), the flocked hook section 3 is moved further forward and rotated 90 degrees in the circumferential direction, and the pull-out hook section 5 is moved so that the hook section 31 of the flocked hook section 3 catches on the proximal hair section 110 (first hair material hooking operation).

[0044] At this time, as the flocked hook portion 3 moves forward, the middle portion of the hook shaft portion 30 is inserted across the adjacent holes 120a and 120b, with the netting threads 121 of the flocked net 100 in between.

[0045] Next, as shown by the arrow in Figure 4(a), the hair implanting hook portion 3 hooked onto the proximal hair portion 110 is retracted, and the pull-out hook portion 5 is returned to its original reference position. Furthermore, the hair implanting hook portion 3 is rotated 90 degrees in the circumferential direction so that the hook portion 31 faces upward, and is pulled out from the hair implantation net 100, passing the middle portion of the proximal hair portion 110 through the holes 120a and 120b, thereby forming the annular portion 112 formed by the proximal hair portion 110 (annular portion formation operation).

[0046] At this time, the latch portion 32 of the flocked hook portion 3 is closed by the netting thread 121 of the flocked net 100, and the flocked hook portion 3 is pulled out of the flocked net 100 while gripping the proximal hair portion 110 of the hair material 101. In addition, the annular portion 112 formed when the engagement portion of the hair material 101 with the flocked hook portion 3 passes through the holes 120a and 120b of the flocked net 100 is exposed from the hole 120a of the flocked net 100 towards the flocked hook portion 3.

[0047] Next, as shown in Figure 4(b), the hair flocking hook part 3 is rotated 360 degrees to twist the annular portion 112 of the hair material 101, raising the hair flocking hook part 3 and shifting it in the width direction Z as shown by the arrow in Figure 4(b) (hair material twisting operation).

[0048] Next, as shown in Figure 5(a), the hair implanting hook portion 3 is advanced beyond the proximal hair portion 110, then slightly retracted and rotated 90 degrees in the circumferential direction, and the hair implanting hook portion 3 is shifted in the width direction Z to return to a position where it overlaps with the hair material 101, and the tip of the hair implanting hook portion 3 is hooked onto the proximal hair portion 110 of the hair material 101 (second hair material hooking operation).

[0049] Next, as shown in Figure 5(b), the flocked hook portion 3 is further retracted and rotated by 90 degrees so that the hook portion 31 faces upward, allowing the portion of the hair material 101 that engages with the flocked hook portion 3 to pass through the annular portion 112, and the first restricting portion 12 restricts the passage of the proximal hair portion 110 through the annular portion 112 (hair material passage operation).

[0050] At this time, the latch portion 32 of the flocked hook portion 3 is closed by the annular portion 112 of the flocked net 100 as it passes through the annular portion 112. Furthermore, the first restricting portion 12 restricts a part of the proximal hair portion 110, specifically the portion on one end 130 side of the net yarn 121, by clamping it with the first clamping portion 80 and the second clamping portion 81. Specifically, the first restricting portion 12 clamps the portion between the engagement portion of the proximal hair portion 110 with the implanted hook portion 3 and the engagement portion of the proximal hair portion 110 with the net yarn 121, thereby restricting movement on the side of the first restricting portion 12 towards the pull-out hook portion 5. The second restricting portion 13 grips and restricts a part of the distal hair portion 111 removed from the removal hole 60, specifically the portion closer to the removal hole 60 than the engaging portion of the pull-out hook portion 5, using the first clamping portion 90 and the second clamping portion 91. Specifically, it grips the portion of the distal hair portion 111 that is exposed from the removal hole 60, between the engaging portion of the removal hole 60 and the pull-out hook portion 5, restricting its movement on the side of the pull-out hook portion 5 that is closer to the second restricting portion 13. Thus, since the hair material 101 is restricted on both sides of the annular portion 112 by the first restricting portion 12 and the second restricting portion 13, the annular portion 112 hardly shrinks even when the hair implanting hook portion 3 retracts. As the hair implanting hook portion 3 retracts, only one end 130 of the proximal hair portion 110 is pulled from the hair implanting hook portion 3, and the annular portion 112 passes through to the one end 130.

[0051] As shown in Figure 6(a), once the annular portion 112 has passed the end 130 of the proximal hair portion 110, the first restricting portion 12 is retracted as indicated by the arrow in Figure 6(a), pulling the proximal hair portion 110 and tightening the annular portion 112 (tightening operation).

[0052] At this time, the pull-out hook portion 5 is locked to the distal hair portion 111, and the second restricting portion 13 maintains a state of gripping the distal hair portion 111. As a result, the distal hair portion 111 does not move beyond the netting yarn 121, and only the annular portion 112 tightens.

[0053] When the annular portion 112 tightens and a knot is formed, the restriction of the second restricting portion 13 is released, the pull-out hook portion 5 is raised and moved to a position offset from the position of the hair material 101, thereby releasing the engagement between the pull-out hook portion 5 and the hair material 101, the pull-out hook portion 5 is lowered, and as shown in Figure 6(b), the hair material pull-in portion 8 pulls in the distal hair portion 111 and moves it downstream in the transport direction T, the eccentric portion 2 is rotated 90 degrees in the opposite direction R2 to change the posture from the second posture to the first posture, and the distal hair portion 111 which is located upstream of the annular portion 112 in the transport direction T is dropped in by the hair material drop-in portion 10 as a result of the posture change (drop-in operation).

[0054] According to the hair implantation device 1 of this embodiment, a hair implantation operation can be performed which includes an annular portion forming operation in which an annular portion 112, which is the middle part of the hair material 101, is passed through the first hole portion 120a and the second hole portion 120b of the hair implantation net 100, and a hair material passing operation in which the hair implantation hook portion 3 is engaged with one end 130 side of the annular portion 112 of the hair material 101, and the hair material 101 is moved so that the engaged portion with the hair implantation hook portion 3 passes through the annular portion 112. In the hair material passing operation, after the engaged portion with the hair implantation hook portion 3 of the hair material 101 has passed through the annular portion 112, the movement of the portion between the engaged portion with the hair implantation hook portion 3 and the annular portion 112 is restricted by the first restricting portion 12, and the hair implantation hook portion 3 is further moved to allow one end 130 side of the hair material 101 to pass through the annular portion 112. This prevents the annular portion 112 from narrowing and becoming smaller as the hair implanting hook portion 3 moves, and allows one end 130 of the hair material 101 to pass through the annular portion 112 as the hair implanting hook portion 3 moves. As a result, the middle of the hair material 101 is hardly narrowed by the annular portion 112, and the hair material 101 can be implanted into the hair implantation net 100 more stably than in the conventional method.

[0055] In the hair implantation device 1 of this embodiment, the first restricting part 12 restricts the movement of the hair material 101 by gripping it, and the hair implantation operation preferably includes a tightening operation in which the first restricting part 12, which is gripping the hair material 101, is moved after the hair material has passed through, so that the annular part 112 becomes smaller. By doing so, the annular part 112 can be tightened more firmly than in the conventional method. As a result, the knots caused by the annular part 112 can be made smaller than in the conventional method, the knots are less noticeable, and the hair material 101 is less likely to fall out of the hair implantation net 100.

[0056] In this embodiment, the hair implantation device 1 preferably includes a second restricting portion 13 that can restrict the movement of the hair material 101 on the other end 131 side than the annular portion 112. This allows the hair material 101 to pass through on the other end 130 side without further constricting the annular portion 112, thus enabling more stable implantation of the hair material 101 onto the hair implantation net 100.

[0057] In the embodiment described above, during the hair material passage operation, after the engagement portion of the hair material 101 with the flocked hook portion 3 passes through the annular portion 112, the portion between the engagement portion of the hair material 101 with the flocked hook portion 3 and the annular portion 112 is clamped by the first restricting portion 12, and after one end 130 of the hair material 101 has completely passed through the annular portion 112, the annular portion 112 is constricted by the first restricting portion 12. However, the present invention is not limited thereto. After the engagement portion of the hair material 101 with the flocked hook portion 3 passes through the annular portion 112, the portion between the engagement portion of the hair material 101 with the flocked hook portion 3 and the annular portion 112 is clamped by the first restricting portion 12, and further, the first restricting portion 12, which is clamping the hair material 101 together with the flocked hook portion 3, may be moved to allow one end 130 of the hair material 101 to pass through the annular portion 112. This shortens the hair transplant procedure time.

[0058] In the embodiment described above, the distal hair portion 111 is restricted by the second restricting portion 13 during the hair material passage operation, but the present invention is not limited thereto. The distal hair portion 111 does not need to be restricted by the second restricting portion 13 during the hair material passage operation, and if it is restricted, the restricting portion only needs to be on the other end 131 side of the portion of the proximal hair portion 110 that engages with the net yarn 121.

[0059] In the embodiment described above, the annular portion 112 was narrowed by moving the first restricting portion 12, but the present invention is not limited thereto. The annular portion 112 may also be narrowed by moving the pull-out hook portion 5 and / or the second restricting portion 13. Alternatively, the annular portion 112 may be narrowed by moving the first restricting portion 12 and the pull-out hook portion 5 and / or the second restricting portion 13 simultaneously.

[0060] In the embodiment described above, the hook portion 31 of the hair implantation hook portion 3 was hooked onto the proximal hair portion 110 during the first hair material hooking operation, but the present invention is not limited thereto. In the first hair material hooking operation, the hook portion 31 of the hair implantation hook portion 3 may be hooked onto the distal hair portion 111.

[0061] In the embodiments described above, the components can be freely substituted or added between each embodiment, as long as they fall within the technical scope of the present invention. [Explanation of Symbols]
