Description

[Technical field]

[0001] The present invention relates to a hair implantation device for implanting hair material into a hair implantation net. [Background technology]

[0002] 2. Description of the Related Art Hair implantation devices that tie hair materials for implantation to a hair implantation net are known (for example, see Patent Document 1). In the hair implantation device of Patent Document 1, a first hook is hooked onto the weft of a hair implantation net supported by an eccentric, and the hooked part is inserted between adjacent holes, sandwiching the weft of the hair implantation net, to form a loop. Then, in the hair implantation device of Patent Document 1, the first hook is used as a reference to hook the distal thread of the hair material, and then, while the hair material is free to move from the stocker, the hooked distal thread is passed through the loop and pulled out, making it possible to implant the hair into the hair implantation net.

[0003] [Patent Document 1] JP 2020-125569 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the hair implantation device of Patent Document 1, the hair material is in a state in which it can move freely from the stocker during the above-mentioned implantation operation, so that the thread on the distal side of the hair material moves in response to the retraction of the first hook. Therefore, when the hair material is short, the thread on the distal side may suddenly fall from the stocker during the retraction of the first hook, causing the hair material to slip through the hooked portion of the first hook. In such a case, the thread on the distal side may not pass through the loop portion, and the hair material may not be implanted into the hair implantation net.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a hair implantation device that can implant hair material into a hair implant net more stably than conventional methods. [Means for solving the problem]

[0006] One aspect of the present invention for solving the above-mentioned problems is a hair transplantation device comprising a net transport unit for transporting a hair transplant net, a hair material supply unit for supplying hair material from a middle portion of the hair material toward the hair transplant net, a hair transplant needle unit for attaching a part of the middle portion of the hair material supplied from the hair material supply unit to the hair transplant net and transplanting the hair, and a regulating unit provided with respect to the supply portion of the hair material from the hair material supply unit and capable of regulating the movement of the hair material from the hair material supply unit.

[0007] According to this aspect, since the restricting portion can restrict the movement of the hair material from the hair material supplying portion, for example, when the hair material is implanted into the hair implantation net using the hair implantation needle portion, the restricting portion can restrict the movement of the hair material from the hair material supplying portion, making it difficult for the hair material to fall out of the hair material supplying portion and difficult for the hair material to come off from the hair implantation needle portion. As a result, the hair material can be implanted into the hair implantation net more stably than in the past.

[0008] In a preferred aspect, the restricting portion is capable of fixing a part of the hair material to prevent the hair material from falling out of the hair material supplying portion.

[0009] In a preferred aspect, the hair material supplying part has a supply port that supplies the hair material downward, and the regulating part is located vertically opposite the hair material supplying part and is capable of clamping a position in the hair material supplying part that is a shortest distance from the supply port to a position within a range of 2 cm or less.

[0010] In a preferred aspect, the regulating portion has a first clamping portion and a second clamping portion, and a part of the hair material is clamped by the first clamping portion and the second clamping portion.

[0011] Incidentally, in the hair implantation operation of the hair implantation device of Patent Document 1, the thread on the distal side of the hair material receives a tensile force from the first hook when the first hook is moved backward. However, since the hair material is in a state in which it can move freely from the stocker as described above, the thread on the distal side also moves from the stocker following the movement of the first hook, and the tensile force of the first hook is not transmitted to the loop portion. Therefore, when the first hook is moved backward, the loop portion is hardly squeezed, and the thread on the distal side of the hair material passes through the loop portion while the loop portion is inflated. Therefore, even after the product is completed, the loop portion may remain in a bulging state, which results in a poor appearance and a problem of low yield.

[0012] Therefore, in a preferred aspect, the hair implant net has a first hole portion, a second hole portion, and a thread portion extending in a direction intersecting the conveying direction to separate the first hole portion and the second hole portion, and a ring-shaped portion forming operation is performed in which a part of the middle portion of the hair material is inserted from the first hole portion to the second hole portion by the hair implant needle portion to form a ring-shaped portion protruding from the second hole portion, and a ring-shaped portion squeezing operation is performed in which the hair implant needle portion hooks a first hair portion, which is a portion of the hair material closer to the first end portion than the first hole portion, and passes it through the ring-shaped portion, and at least one of the following operations (1) or (2) is performed to squeeze the ring-shaped portion. (1) The first hair portion is moved in a direction away from the thread portion by the hair-implanting needle portion. (2) The second hair part, which is a part of the hair material closer to the second end side than the first hole part, is hooked by the pulling needle part and moved in a direction away from the thread part.

[0013] According to this aspect, the annular portion can be narrowed to a degree that does not impede the passage of the first hair portion through the annular portion in the annular portion narrowing operation, so that the annular portion can be made small and the hair material can be firmly fixed to the hair implant net. Therefore, the hair material looks better and can be implanted stably on the hair implant net compared to the conventional method.

[0014] In a preferred aspect, the restricting portion fixes a part of the first hair portion and / or a part of the second hair portion.

[0015] In a preferred aspect, the restricting portion fixes a part of the first hair portion and a part of the second hair portion.

[0016] A preferred aspect includes a tensioning member for applying tension to the hair material during the annular squeezing action.

[0017] In a preferred aspect, the tensioning member is a pulling needle portion which hooks the second hair portion.

[0018] The above-described aspects may be made dependent on each other, some of the configurations may be cited, or some of the configurations may be substituted for each other, as long as they are included in the technical scope of the present invention. Effect of the Invention

[0019] According to the present invention, hair material can be implanted in a hair implant net more stably than in the conventional method. [Brief description of the drawings]

[0029] (Hair material supply section 6) The hair material supply section 6 is a hair material storage section that stores the hair material 101 to be implanted in the hair implant net 100, and as shown in Figure 1, is provided with an extraction hole 55 (supply port) for removing and supplying the hair material 101 stored in the bottom.

[0030] (Induction Roll 7) As shown in FIG. 1(b), the guide roll 7 has a groove 70 on a part of its outer circumferential surface, and a part of the hair material 101 pulled out from the hair material supply section 6 by the pulling hook section 5 passes through the groove 70, thereby adjusting the position in the axial direction L to fall within a predetermined range.

[0031] (Hair material inlet part 8) The hair material drawing section 8 is a drawing bar that draws the hair material 101 drawn from the hair material supply section 6 by the drawing hook section 5 upstream in the transport direction T from the implantation position of the hair implantation net 100.

[0032] (Hair material recess 10) The hair material dropping section 10 is a dropping bar that drops the hair material 101 pulled out from the hair material supply section 6 by the pulling hook section 5 below the implantation position of the hair implantation net 100.

[0033] (Transport roll 11) The transport roll 11 is a support roll that supports the implanted net 100 so that the implanted net 100 passes over the eccentric portion 2, and is a net transport portion that transports the implanted net 100 in the transport direction T by rotating.

[0034] (Regulatory Mechanism 12) As shown in Figure 2, the regulating mechanism 12 has a first clamping portion 80 and a second clamping portion 81, and is a regulating portion that regulates the movement of the hair material 101 by clamping a portion of the hair material 101 between the first clamping portion 80 and the second clamping portion 81.

[0035] The first clamping portion 80 includes a first base portion 85 and a first guide portion 86, as shown in FIG. The first base portion 85 is a plate-shaped portion that has a width in the front-rear direction X and extends in the width direction W. The first guide portion 86 is a protruding piece that protrudes forward from the front end portion in the front-rear direction X of the first base portion 85.

[0036] The second clamping portion 81 is a portion that is paired with the first clamping portion 80 and clamps a part of the hair material 101 . As shown in FIG. 2, the second clamping portion 81 includes a second base portion 95 and a second guide portion 96. The second base portion 95 is a plate-shaped portion that has a width in the front-rear direction X and extends in the width direction W. The second guide portion 96 is a protruding piece that protrudes forward from the front end portion in the front-rear direction X of the second base portion 95.

[0037] The regulating mechanism 12 has a first base portion 85 of the first clamping portion 80 and a second base portion 95 of the second clamping portion 81 overlapping in the vertical direction Y, and a first guide portion 86 of the first clamping portion 80 and a second guide portion 96 of the second clamping portion 81 protruding in the same direction (forward direction). The regulating mechanism 12 is capable of changing its position between a released position in which the first guide portion 86 of the first clamping portion 80 and the second guide portion 96 of the second clamping portion 81 are shifted in the width direction W as shown in FIG. 2(a) and a clamping position in which the first guide portion 86 of the first clamping portion 80 and the second guide portion 96 of the second clamping portion 81 overlap in the width direction W as shown in FIG. 2(b). The regulating mechanism 12 is capable of clamping a part of the hair material 101 hanging down from the hair material supplying section 6 by changing its position from the release position to the clamping position.

[0038] (Hair transplant net 100) The flocked net 100 is an expandable net formed in a mesh shape by a plurality of net threads 121 (thread portions) as shown in FIG. The flocked net 100 of this embodiment has a honeycomb structure and is stretchable in the conveying direction T and the width direction W. The hole 120 is a hexagonal hole when viewed in a plan view, and each side is formed by a net thread 121.

[0039] (Hair Material 101) The hair material 101 is a filament to be implanted in the hair implant net 100. The hair material 101 may be artificial hair made of resin fibers or the like, human hair, animal hair, or the like. The hair material 101 of this embodiment is bundled together and used as a hair bundle.

[0040] Next, the positional relationship of each part of the hair implantation device 1 of this embodiment will be described. Note that the eccentric part 2 will be described based on the first position in which the recess 28 of the main body part 20 in FIG. 1 is located on the hair implantation hook part 3 side and faces the hair implantation hook part 3 side.

[0041] In the hair implantation device 1, as shown in FIG. 1, a hair implantation net 100 is suspended between an eccentric section 2 and each of transport rolls 11. The eccentric portion 2 has rotating shaft portions 21a and 21b journaled thereon, and is rotatable in the circumferential direction about the rotating shaft portions 21a and 21b.

[0042] As shown in FIG. 1, the hair implantation hook portion 3 is in a horizontal position extending horizontally, and the hook portion 51 faces the recess 28 of the main body portion 20 in the front-rear direction X. The pulling hook part 5 has a hook part 61 at the tip located on the upper side, and is in a vertical position extending vertically, and faces the extraction hole 55 of the hair material supply part 6 in the height direction Y (up-down direction). The hair material intake portion 8 is located below the hair material supply portion 6 and above the eccentric portion 2 in the height direction Y.

[0043] As shown in Figure 1, the regulating mechanism 12 is located vertically opposite the hair material supply section 6, and is preferably capable of clamping a position whose shortest distance from the extraction hole 55 of the hair material 101 is in the range of 0 cm to 2 cm, and more preferably is capable of clamping a position whose shortest distance is in the range of more than 0 cm to 1 cm.

[0044] Next, the hair implantation operation of the hair implantation device 1 of this embodiment will be described.

[0045] First, as shown in FIG. 3(a), the hair implantation operation of the hair implantation device 1 is performed by raising the withdrawal hook portion 5 to hook onto the hair material 101 in the hair material supply portion 6, then lowering it to the original reference position to pull out the middle portion of the hair material 101 in the hair material supply portion 6 downward through the removal hole 55, and shifting the withdrawal hook portion 5 from the reference position in the axial direction L of the eccentric portion 2 (hair material pulling-out operation).

[0046] At this time, the hair material 101 in the hair material supply unit 6 is pulled out in a "V" shape by the hook portion 61 of the pulling hook portion 5 as shown in Fig. 3(a), and the engagement portion (hooking portion) with the hook portion 61 of the pulling hook portion 5 is lower than the apex of the eccentric portion 2. Also, the hair material 101 is divided into a proximal hair portion 110 (first hair portion) and a distal hair portion 111 (second hair portion) based on the engagement portion (folded back portion) with the hook portion 61 of the pulling hook portion 5. Further, the restriction mechanism 12 is in the released position shown in FIG. 2(a), and the hair material 101 is positioned between the guide portions 86, 96 but is not in contact with the guide portions 86, 96.

[0047] In addition, in a separate operation from the hair material pulling-out operation, as shown by the arrow in Fig. 3(a), the hair implantation hook part 3 is advanced toward the eccentric part 2, and the hook part 51 of the hair implantation hook part 3 is passed through the hole part 120a of the hair implantation net 100 on the eccentric part 2 and placed in the recess 28 of the eccentric part 2. Then, as shown in Fig. 3(b), the hair implantation hook part 3 is retracted from the recess 28 of the eccentric part 2 and raised (net hooking operation).

[0048] At this time, the hair implantation hook unit 3, by retracting and rising, hooks the net thread 121, which is the weft thread constituting the edge of the hole 120a of the hair implantation net 100 on the eccentric unit 2, with the hook unit 51 and lifts it upward. That is, the hair implantation hook unit 3 hooks the hook unit 51 to the net thread 121 extending in a cross direction (in this embodiment, a perpendicular direction) to the conveying direction T.

[0049] Next, with the hair implantation hook portion 3 hooked onto the net 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 bring the hook portion 51 of the hair implantation hook portion 3 out of the recess 28 (eccentric rotation operation).

[0050] At this time, as the eccentric portion 2 rotates, the hair implantation hook portion 3 is inserted across the adjacent holes 120a, 120b, sandwiching the net thread 121 of the hair implantation net 100.

[0051] Next, as shown in Figure 4(a), the hair implantation hook portion 3 is further advanced and rotated 90 degrees in the circumferential direction, and the extraction hook portion 5 is moved so that the hook portion 51 of the hair implantation hook portion 3 hooks onto the proximal hair portion 110 (first hair material hooking operation).

[0052] At this time, as the hair implantation hook portion 3 advances, a part of the needle shaft portion 50 is inserted across the adjacent holes 120a, 120b, sandwiching the net thread 121 of the hair implantation net 100.

[0053] Next, the hair implantation hook portion 3 is retracted as shown by the arrow in Figure 4 (a) and the withdrawal hook portion 5 is returned to its original reference position, and then the hair implantation hook portion 3 is rotated 90 degrees in the circumferential direction so that the hook portion 51 faces upward, and is pulled out from the hair implantation net 100 to form the annular portion 112 (annular portion forming operation).

[0054] At this time, the latch portion 52 of the hair implant hook part 3 is closed by the net thread 121 of the hair implant net 100, and the hair implant hook part 3 is pulled out from the hair implant net 100 while gripping the proximal hair part 110 of the hair material 101. In addition, the middle part of the hair material 101 passes through the holes 120a and 120b of the hair implant net 100, forming the ring part 112, which is exposed from the first hole 120a of the hair implant net 100 to the hair implant hook part 3 side.

[0055] Next, as shown in FIG. 4(b), the hair implantation hook portion 3 is rotated 360 degrees to twist the annular portion 112 of the hair material 101, and the hair implantation hook portion 3 is raised as shown by the arrow in FIG. 4(b) and shifted in the axial direction L of the eccentric portion 2 (hair material twisting operation).

[0056] Next, as shown in Figure 5 (a), the hair implant hook part 3 is advanced beyond the proximal hair part 110, then the hair implant hook part 3 is moved back slightly and rotated 90 degrees in the circumferential direction, the hair implant hook part 3 is shifted in the axial direction L of the eccentric part 2 and returned to a position overlapping with the hair material 101, and the tip of the hair implant hook part 3 is hooked onto the proximal hair part 110 of the hair material 101 (second hair material hooking operation).

[0057] 2(b) and 5(b), the regulating mechanism 12 is changed from the released position to the clamping position, so that a part of the hair material 101 is clamped by the first guide portion 86 of the first clamping portion 80 and the second guide portion 96 of the second clamping portion 81, thereby restricting the movement of the hair material 101 from the hair material supply portion 6. Then, the hair implantation hook portion 3 is further moved backward and rotated 90 degrees so that the hook portion 51 faces upward, and the engaged portion of the hair material 101 with the hair implantation hook portion 3 is passed through the annular portion 112 (annular portion passing operation).

[0058] At this time, the latch portion 52 of the hair implantation hook portion 3 is closed by the annular portion 112 of the hair implantation net 100. 2(b), the hair material 101 is positioned between the guide parts 86, 96 and is clamped by the guide parts 86, 96. That is, the hair material 101 is restricted from moving from the hair material supply part 6 by the regulating mechanism 12, so that as the hair implantation hook part 3 retracts, all of the tensile force of the hair implantation hook part 3 becomes a force squeezing the annular part 112, and the annular part 112 tightens and becomes smaller. At this time, since the pulling hook portion 5 is kept hooked on the distal hair portion 111, the hair implantation hook portion 3 moves while the hair material 101 maintains tension.

[0059] Next, when the annular portion 112 is narrowed by the annular portion passing action to an extent that the hair material 101 can pass inside the annular portion 112, the regulating mechanism 12 is put into the released position, and the hair implantation hook portion 3 is rotated 720 degrees while being further moved backward to pass the distal hair portion 111 through the annular portion 112, and the extraction hook portion 5 is lowered (hair material twisting action), as shown in Figure 6 (a).

[0060] At this time, it is preferable that the annular portion 112 is narrowed so that the internal area (area of ​​the hole) becomes 1.05 to 2 times the cross-sectional area of ​​the hair material 101 by the passing action of the annular portion. At this time, as the hair implantation hook portion 3 moves backward, the annular portion 112 is further squeezed to form a knot.

[0061] Next, as shown in FIG. 6(b), the distal hair portion 111 is pulled in by the hair material pulling-in portion 8 and flows upstream in the conveying direction T, the eccentric portion 2 is rotated 90 degrees in the reverse direction R2 to change its position from the second position to the first position, and the hair material is dropped by the hair material dropping-in portion 10 (dropping-in operation).

[0062] According to the hair implantation device 1 of this embodiment, the regulating mechanism 12 can regulate the movement of the hair material 101 from the hair material supply unit 6, so that when the hair material 101 is implanted into the hair implant net 100 by the hair implant hook unit 3, the regulating mechanism 12 regulates the movement of the hair material 101 from the hair material supply unit 6, making it difficult for the hair material 101 to fall from the hair material supply unit 6 and difficult for the hair material 101 to come off from the hair implant hook unit 3. As a result, the hair material 101 can be implanted into the hair implant net 100 more stably than before.

[0063] According to the hair implantation device 1 of the present embodiment, the regulating mechanism 12 can fix a part of the hair material 101 to prevent the hair material 101 from falling out from the hair material supplying part 6. Therefore, in the annular part passing operation, it is possible to prevent the hair material 101 from suddenly falling out from the hair material supplying part 6 in association with the operation of the hair implantation hook part 3, and the hair material 101 can be stably implanted in the hair implantation net 100.

[0064] According to the hair implantation device 1 of this embodiment, the hair material supplying part 6 has an outlet hole 55 constituting a supply port for supplying the hair material 101 downward, and the regulating mechanism 12 is capable of regulating a position that is vertically opposite to the hair material supplying part 6 and is within a range of a shortest distance of 2 cm from the outlet hole 55 in the supply part of the hair material 101. In other words, since the regulating mechanism 12 can regulate at a position close to the hair material supplying part 6, the hair material 101 is less likely to fall out of the hair material supplying part 6.

[0065] According to the hair implantation device 1 of this embodiment, the regulating mechanism 12 has a first clamping portion 80 and a second clamping portion 81, and clamps a part of the hair material 101 between the clamping portions 80, 81, so that the movement of the hair material 101 can be easily regulated.

[0066] According to the hair implantation device 1 of the present embodiment, an annular portion forming operation is performed in which a part of the middle portion of the hair material 101 is inserted across from the first hole portion 120a to the second hole portion 120b by the hair implantation hook portion 3 to form the annular portion 112 protruding from the second hole portion 120b, and an annular portion squeezing operation is performed in which the proximal hair portion 110, which is the portion of the hair material 101 closer to the first end portion than the first hole portion 120a, is hooked by the hair implantation hook portion 3 and passed through the annular portion 112, and the proximal hair portion 110 is moved in a direction away from the net thread 121 by the hair implantation hook portion 3 to squeeze the annular portion 112. Therefore, the annular portion 112 is easily squeezed, the knot by the annular portion 112 can be made smaller, and the hair material 101 can be implanted in the hair implantation net 100 with a better appearance than in the past.

[0067] According to the hair transplant device 1 of this embodiment, the regulating mechanism 12 fixes a portion of the proximal hair portion 110 and a portion of the distal hair portion 111, respectively, so that during the annular portion squeezing operation, the hair material 101 does not move within the hair material supply section 6, and the annular portion 112 of the hair material 101 can be stably squeezed.

[0068] According to the hair transplant device 1 of this embodiment, the withdrawal hook portion 5 functions as a tensioning member that applies tension to the hair material 101 by hooking the distal hair portion 111, which is the portion of the hair material 101 closer to the second end side than the second hole portion 120b, during the annular portion tightening operation, making it easier to tighten the annular portion 112 and the knot.

[0069] In the above embodiment, the annular portion 112 is narrowed by moving the tufted hook part 3 backward during the annular portion passing operation, but the present invention is not limited to this. For example, the annular portion 112 may be narrowed by lifting the tufted hook part 3. That is, the annular portion 112 may be narrowed by moving the tufted hook part 3 in a direction away from the net thread 121 other than the front-rear direction X.

[0070] In the above embodiment, the ring-shaped portion 112 is squeezed by pulling the hair implantation hook part 3 in a direction away from the net thread 121 while both ends of the hair material 101 are fixed by the regulating mechanism 12 during the ring-shaped portion passing operation, but the present invention is not limited to this. As shown in Fig. 7(a), the ring-shaped portion 112 may be squeezed by moving and pulling the pull-out hook part 5 in a direction away from the net thread 121 (for example, downward) while both ends of the hair material 101 are fixed by the regulating mechanism 12. In this case, when the annular portion 112 is narrowed to an extent that the hair material 101 can pass inside the annular portion 112, the regulating mechanism 12 is put into the released position as shown in Figure 7 (b), and the hair implantation hook portion 3 is rotated 720 degrees and retreated to allow the distal hair portion 111 to pass through the annular portion 112. Alternatively, while both ends of the hair material 101 are fixed by the regulating mechanism 12, the annular portion 112 may be squeezed by pulling the hair implantation hook portion 3 and the pull-out hook portion 5 simultaneously or sequentially in a direction away from the net thread 121.

[0071] In the above embodiment, the restricting mechanism 12 clamps and fixes both the proximal hair portion 110 and the distal hair portion 111, but the present invention is not limited to this. Only one of the proximal hair portion 110 and the distal hair portion 111 may be fixed. For example, when the hair implantation hook portion 3 is retracted to narrow the annular portion 112 in the annular portion passing operation, only the distal hair portion 111 may be fixed, and when the withdrawal hook portion 5 is moved to narrow the annular portion 112, only the proximal hair portion 110 may be fixed.

[0072] In the above embodiment, in the first hair material hooking operation, the hook portion 51 of the hair implant hook part 3 is hooked on the proximal hair portion 110, but the present invention is not limited to this. In the first hair material hooking operation, the hook portion 51 of the hair implant hook part 3 may be hooked on the distal hair portion 111.

[0073] In the above embodiment, the regulating mechanism 12 clamps the hair material 101 by relatively moving the clamping parts 80, 81 only in the width direction W, but the present invention is not limited to this. The regulating mechanism 12 may clamp the hair material 101 by moving the clamping parts 80, 81 in the front-rear direction X in addition to the width direction W. In this way, excess hair material 101 that cannot be used for hair transplantation and protrudes from the extraction hole 55 of the hair material supplying part 6 can be clamped in the width direction W and moved in the front-rear direction X, and removed from the hair material supplying part 6.

[0074] In the above embodiment, the guide portions 86, 96 of the clamping portions 80, 81 of the regulating mechanism 12 extend forward, but the present invention is not limited to this. As long as the regulating mechanism 12 can regulate the hair material 101, the extending direction of the guide portions 86, 96 of the clamping portions 80, 81 is not limited. For example, the guide portions 86, 96 of the clamping portions 80, 81 may extend rearward and clamp the hair material 101 from the front side (the hair implantation hook portion 3 side).

[0075] In the above-described embodiments, each component may be freely substituted or added between the respective embodiments as long as it falls within the technical scope of the present invention. [Explanation of symbols]
