Description

Technical Field

[0001] The invention relates to a hair transplanting device for transplanting hair material relative to a hair transplanting net. Background Art

[0002] Conventionally, there is known a hair transplanting device that connects a hair material for hair transplanting to a hair transplanting net (for example, Patent Document 1).

[0003] In the hair transplanting device of Patent Document 1, a first hook is hooked relative to the weft of the hair transplanting net supported by an eccentric wheel, and the hooking portion is inserted between the holes adjacent to each other across the weft of the hair transplanting net to form a loop. Then, in the hair transplanting device of Patent Document 1, with the first hook as a reference, after the first hook is hooked on the thread on the far side of the hair material, the thread on the far side of the hook is pulled through the loop while the hair material can move freely from the storage container, thereby enabling hair transplanting relative to the hair transplanting net.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2020-125569

[0005] However, in the hair implanting device of Patent Document 1, during the above-mentioned hair implanting action, the hair material is in a state where it can move freely from the storage container, so the thread on the far side of the hair material moves along with the retreating action of the first hook. Therefore, in the case where the hair material is short, the thread on the far side may accidentally fall from the storage container during the retreating action of the first hook, and the hair material may pass through the hooking portion of the first hook. In this case, the thread on the far side may not pass through the loop, and the hair material may not be implanted on the hair implanting net. Summary of the invention

[0006] Therefore, an object of the present invention is to provide a hair transplanting device capable of transplanting hair material more stably with respect to a hair transplanting net than in the past.

[0007] One embodiment of the present invention for solving the above-mentioned problems is a hair implantation device, comprising: a net conveying section for conveying a hair implantation net; a hair material supplying section for supplying hair material from a middle portion of the hair material toward the hair implantation net; a hair implantation needle section for mounting a part of the middle portion of the hair material supplied from the hair material supplying section relative to the hair implantation net to perform hair implantation; and a limiting section provided relative to a supply portion of the hair material from the hair material supplying section and capable of limiting movement of the hair material from the hair material supplying section.

[0008] According to this embodiment, the movement of the hair material from the hair material supply portion can be limited by the limiting portion, so that, for example, when the hair material is transplanted to the hair transplanting net based on the hair transplanting needle portion, the movement of the hair material from the hair material supply portion is limited by the limiting portion, thereby making it difficult for the hair material to fall off the hair material supply portion and making it difficult for the hair material to be separated from the hair transplanting needle portion. As a result, the hair material can be transplanted more stably with respect to the hair transplanting net than before.

[0009] Preferably, the restricting portion fixes a portion of the hair material to prevent the hair material from falling off the hair material supplying portion.

[0010] Preferably, the hair material supply portion has a supply port for supplying the hair material downward, and the limiting portion is capable of clamping a position that is opposed to the hair material supply portion in a vertical direction and is a position in a range where the shortest distance from the supply port is 2 cm or less in the hair material supply portion.

[0011] In a preferred embodiment, the limiting portion includes a first clamping portion and a second clamping portion, and a portion of the hair material is clamped by the first clamping portion and the second clamping portion.

[0012] However, in the hair implanting action of the hair implanting device of patent document 1, the thread on the distal side of the hair material is subjected to tensile force from the first hook in the retreating action of the first hook, but as described above, the hair material is in a state where it can move freely from the storage container, so the thread on the distal side also moves from the storage container following the movement of the first hook, and the tensile force of the first hook will not be transmitted to the loop. Therefore, in the retreating action of the first hook, the loop is hardly tightened, and the thread on the distal side of the hair material passes through the loop while the loop remains bulging. Therefore, after being completed as a product, the loop sometimes becomes bulging, and there are problems of poor appearance and poor yield rate.

[0013] Therefore, a preferred embodiment is that the hair implanting net has a first hole portion, a second hole portion, and a line portion extending along a cross direction relative to the conveying direction to divide the first hole portion and the second hole portion, and the hair implanting device performs: a ring-shaped portion forming action, in which a part of the middle portion of the hair material is inserted from the first hole portion to the second hole portion through the hair implanting needle portion to form a ring-shaped portion extending from the second hole portion; and a ring-shaped portion tightening action, in which the hair implanting needle portion hooks the part of the hair material that is closer to the first end side than the first hole portion, that is, the first hair portion, and passes it through the ring-shaped portion, and performs at least one of the following actions (1) or (2) to tighten the ring-shaped portion.

[0014] (1) The first hair portion is moved in a direction away from the thread portion by the hair implantation needle portion.

[0015] (2) Pull in the needle part to hook the part of the hair material on the second end side of the first hole part, that is, the second hair part, and move it in a direction away from the wire part.

[0016] According to this method, in the tightening action of the annular part, in order to make the first hair part pass through the annular part, the annular part can be tightened to such an extent that it will not become an obstacle. Therefore, the annular part can be reduced and the hair material can be firmly fixed to the hair implanting net. Therefore, compared with the prior art, the hair material can be implanted on the hair implanting net with good appearance and stability.

[0017] Preferably, the restricting part fixes a part of the first hair part and / or a part of the second hair part.

[0018] Preferably, the restricting part fixes a part of the first hair part and a part of the second hair part.

[0019] Preferably, a tension applying member for applying tension to the hair material during the tightening action of the annular part is provided.

[0020] Preferably, the tension applying member is the pulling-in needle part that hooks the second hair part.

[0021] As long as the above methods are included within the technical scope of the present invention, the methods can be subordinate to each other, reference a part of the configuration, or replace a part of the configuration among the various methods.

[0022] Effects of the Invention

[0023] According to the present invention, compared with the prior art, the hair material can be implanted on the hair implanting net more stably. Description of the Drawings

[0067] The hook needle part 5 is a rod-shaped body with a hook claw at the front end. Figure 1 As shown, a needle shaft portion 60 and a hook portion 61 are provided.

[0068] (Hair material supply unit 6)

[0069] The hair material supplying section 6 is a hair material receiving section for receiving the hair material 101 to be transplanted to the hair transplanting net 100. Figure 1 As shown, a take-out hole 55 (supply port) for taking out and supplying the stored hair material 101 is provided at the bottom.

[0070] (Guide Roller 7)

[0071] like Figure 1 As shown in (b), the guide roller 7 is a roller having a groove 70 on a part of the outer peripheral surface, and a part of the hair material 101 pulled out from the hair material supply part 6 by the pulling hook part 5 passes through the groove 70, thereby adjusting the position in the axial direction L to converge within a predetermined range.

[0072] (Hair material pulling-in portion 8)

[0073] The hair material pulling part 8 is a pulling rod that pulls the hair material 101 pulled out from the hair material supply part 6 by the pulling hook part 5 toward the downstream side in the transport direction T of the hair implantation position of the hair implantation net 100 .

[0074] (Hair material falling portion 10)

[0075] The hair material dropping part 10 is a dropping rod that causes the hair material 101 pulled out from the hair material supply part 6 by the pulling hook part 5 to drop to the lower side than the hair implantation position of the hair implantation net 100 .

[0076] (Conveyor roller 11)

[0077] The transport roller 11 is a support roller that supports the wool implanted web 100 so that the wool implanted web 100 passes over the eccentric portion 2 , and is a web transport portion that transports the wool implanted web 100 in the transport direction T by rotating.

[0078] (Restriction Agency 12)

[0079] like Figure 2 As shown, the restriction mechanism 12 is a restriction portion including a first clamping portion 80 and a second clamping portion 81 , and the first clamping portion 80 and the second clamping portion 81 clamp a part of the hair material 101 to restrict movement of the hair material 101 .

[0080] like Figure 2 As shown, the first clamping portion 80 includes a first base portion 85 and a first guide portion 86 .

[0081] The first base portion 85 is a plate-shaped portion that has a width in the front-rear direction X and extends along the width direction W.

[0082] The first guide portion 86 is a protruding piece that protrudes toward the front side from the front side end portion of the first base portion 85 in the front-rear direction X.

[0083] The second clamping portion 81 is a portion that forms a pair with the first clamping portion 80 and clamps a part of the hair material 101 .

[0084] like Figure 2 As shown, the second clamping portion 81 includes a second base portion 95 and a second guide portion 96 .

[0085] The second base portion 95 is a plate-shaped portion that has a width in the front-rear direction X and extends along the width direction W.

[0086] The second guide portion 96 is a protruding piece that protrudes toward the front side from the front side end portion of the second base portion 95 in the front-rear direction X.

[0087] The limiting mechanism 12 is such that the first base portion 85 of the first clamping portion 80 and the second base portion 95 of the second clamping portion 81 overlap in the vertical direction Y, and the first guide portion 86 of the first clamping portion 80 and the second guide portion 96 of the second clamping portion 81 extend in the same direction (forward direction).

[0088] The limiting mechanism 12 is configured such that the first clamping portion 80 and the second clamping portion 81 slide relative to each other in the width direction W, thereby being able to Figure 2 The release posture 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 offset in the width direction W, and Figure 2The first guide portion 86 of the first clamping portion 80 and the second guide portion 96 of the second clamping portion 81 shown in (b) are changed in position between the clamping positions in which they overlap in the width direction W.

[0089] The restricting mechanism 12 can clamp a part of the hair material 101 hanging down from the hair material supply part 6 by changing its position from the release position to the clamping position.

[0090] (Planting net 100)

[0091] like Figure 1 As shown, the hair implantation net 100 is a stretchable net formed of a plurality of net wires 121 (wire portions) in a mesh shape and has a plurality of holes 120 .

[0092] The wool implantation net 100 of the present embodiment has a honeycomb structure and is expandable and contractible in the transport direction T and the width direction W.

[0093] The hole 120 is a hexagonal hole in a plan view, and each side is formed by a mesh wire 121 .

[0094] (Hair Materials 101)

[0095] The hair material 101 is a linear body that is implanted on the hair implantation net 100 .

[0096] As the hair material 101, artificial hair made of resin fiber or the like, human hair, animal hair, or the like can be used.

[0097] The hair material 101 of this embodiment is used as a hair bundle by bundling a plurality of hairs.

[0098] Next, the positional relationship of each part of the hair implanting device 1 of this embodiment will be described. Figure 1 The description will be made based on the first posture in which the recessed portion 28 of the main body 20 is located on the hair implantation hook needle portion 3 side and faces the hair implantation hook needle portion 3 side.

[0099] like Figure 1 As shown, the hair implanting device 1 includes a hair implanting net 100 suspended on an eccentric portion 2 and each conveying roller 11 .

[0100] The eccentric portion 2 is rotatable in the circumferential direction around the rotating shaft portions 21 a and 21 b by pivotally supporting the rotating shaft portions 21 a and 21 b.

[0101] like Figure 1 As shown, the hair implantation hook needle part 3 is in a horizontal posture extending in the horizontal direction, and the hook part 51 faces the recessed part 28 of the main body part 20 in the front-back direction X.

[0102] The hook part 5 is in a vertical posture with the hook part 61 at the front end located upward and extending in the vertical direction, and faces the extraction hole 55 of the hair material supply part 6 in the height direction Y (vertical direction).

[0103] The hair material pulling part 8 is located below the hair material supply part 6 in the height direction Y and is located above the eccentric part 2 .

[0104] like Figure 1 As shown, the limiting mechanism 12 is preferably capable of clamping a position that is opposed to the hair material supply portion 6 in the vertical direction and is a position where the shortest distance between the hair material 101 and the extraction hole 55 is in a range of 0 cm to 2 cm, and more preferably a position that is in a range of more than 0 cm and 1 cm or less.

[0105] Next, the hair transplanting operation of the hair transplanting device 1 of this embodiment will be described.

[0106] First, the hair implanting action of the hair implanting device 1 is as follows: Figure 3 As shown in (a), after the pull-out hook part 5 is raised and hooks the hair material 101 in the hair material supply part 6, it is lowered to the original reference position and the middle part of the hair material 101 in the hair material supply part 6 is pulled downward from the extraction hole 55, so that the pull-out hook part 5 is offset from the reference position to the axial direction L of the eccentric part 2 (hair material pulling action).

[0107] At this time, if Figure 3 As shown in (a), the hair material 101 in the hair material supply part 6 is pulled out in a "V" shape by the hook part 61 of the pull-out hook part 5, and the engagement part (hook part) engaged with the hook part 61 of the pull-out hook part 5 becomes a position lower than the top of the eccentric part 2. In addition, the hair material 101 is divided into a proximal side hair part 110 (first hair part) and a distal side hair part 111 (second hair part) based on the engagement part (turned part) engaged with the hook part 61 of the pull-out hook part 5.

[0108] In addition, the limiting mechanism 12 becomes Figure 2 In the release posture shown in (a), the hair material 101 is located between the guide parts 86 and 96, but does not contact the guide parts 86 and 96.

[0109] Furthermore, in actions different from the hair material pulling action, e.g. Figure 3 As shown by the arrow in (a), the hair-planting hook needle part 3 moves toward the eccentric part 2, so that the hook part 51 of the hair-planting hook needle part 3 passes through the hole part 120a of the hair-planting net 100 on the eccentric part 2 and is arranged in the recess 28 of the eccentric part 2. Then, as shown in FIG. Figure 3As shown in (b), the hair implanting hook needle part 3 is retreated from the recessed part 28 of the eccentric part 2 and raised (net hooking action).

[0110] At this time, the hair-planting hook needle part 3 moves backward and upward to hook the weft wires, i.e., the mesh wires 121, which are the edges of the hole 120a of the hair-planting net 100 on the eccentric part 2 with the hook part 51 and lifts it upward. That is, the hair-planting hook needle part 3 hooks the hook part 51 to the mesh wires 121 extending along the intersecting direction (orthogonal direction in this embodiment) intersecting the conveying direction T.

[0111] Next, when the hair implanting hook needle part 3 is hooked on the mesh line 121, Figure 3 As shown by the arrow in (b), the eccentric portion 2 is rotated 90 degrees in the forward direction R1, so that the hook portion 51 of the hair implanting hook needle portion 3 is extended from the recess 28 (eccentric wheel rotation operation).

[0112] At this time, as the eccentric portion 2 rotates, the hair implantation hook portion 3 is inserted across the holes 120a and 120b of the hair implantation net 100 that are adjacent to each other with the net wire 121 interposed therebetween.

[0113] Then, if Figure 4 As shown in (a), the hair transplanting hook needle part 3 is further advanced and the hair transplanting hook needle part 3 is rotated 90 degrees in the circumferential direction, and the pull-out hook needle part 5 is moved so that the hook part 51 of the hair transplanting hook needle part 3 is hooked on the proximal side hair part 110 (the first hair material hooking action).

[0114] At this time, due to the advancement of the hair implantation hook needle part 3, a part of the needle shaft part 50 is inserted through the adjacent hole parts 120a and 120b of the hair implantation net 100 across the net line 121.

[0115] Then, if Figure 4 As shown by the arrow in (a), the hair-implanting crochet needle part 3 is retreated and the pulled-out crochet needle part 5 is returned to the original reference position, and the hair-implanting crochet needle part 3 is further rotated 90 degrees in the circumferential direction so that the hook part 51 is facing upward, and the annular part 112 is pulled out from the hair-implanting net 100 to form a ring-shaped part (annular part forming action).

[0116] At this time, the latch portion 52 of the hair implanting hook part 3 is closed by the mesh line 121 of the hair implanting net 100, and the hair implanting hook part 3 is pulled out from the hair implanting net 100 while grasping the proximal side 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 implanting net 100 to form an annular portion 112, and the annular portion 112 is exposed from the first hole 120a of the hair implanting net 100 to the hair implanting hook part 3 side.

[0117] Then, if Figure 4As shown in (b), the hair implanting hook needle portion 3 is rotated 360 degrees to twist the annular portion 112 of the hair material 101, as shown in Figure 4 As shown by the arrow in (b), the hair implanting hook part 3 is raised and shifted in the axial direction L of the eccentric part 2 (twisting action of the hair material).

[0118] Then, if Figure 5 As shown in (a), the hair transplanting hook needle part 3 is advanced beyond the proximal side hair part 110, the hair transplanting hook needle part 3 is slightly retreated and rotated 90 degrees in the circumferential direction, the hair transplanting hook needle part 3 is offset to the axial direction L of the eccentric part 2 and returned to the position overlapping with the hair material 101, and the front end of the hair transplanting hook needle part 3 is hooked on the proximal side hair part 110 of the hair material 101 (the second hair material hooking action).

[0119] Then, if Figure 2 (b) Figure 5 As shown in (b), the limiting mechanism 12 is changed from the release posture to the clamping posture, and a part of the hair material 101 (the distal side hair part 111) is clamped by the first guide part 86 of the first clamping part 80 and the second guide part 96 of the second clamping part 81, and the movement of the hair material 101 from the hair material supply part 6 is restricted. Then, the hair implanting hook part 3 is further retreated and rotated 90 degrees to a posture in which the hook part 51 faces upward, and the engaging part of the hair material 101 with the hair implanting hook part 3 passes through the annular part 112 (annular part passing action).

[0120] 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 .

[0121] In addition, the limiting mechanism 12 becomes Figure 2 In the clamping posture shown in (b), the hair material 101 is located 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 restriction mechanism 12, so that as the hair implanting hook part 3 retreats, the tensile force of the hair implanting hook part 3 all becomes the force to tighten the annular part 112, and the annular part 112 tightens and becomes smaller.

[0122] At this time, since the pulling hook part 5 maintains the state of being hooked on the distal side hair part 111, the hair implanting hook part 3 moves in the state where the hair material 101 maintains the tension.

[0123] Next, when the ring-shaped portion 112 is tightened to the extent that the hair material 101 can pass through the inside of the ring-shaped portion 112 through the ring-shaped portion passing action, as shown in FIG. Figure 6 As shown in (a), the limiting mechanism 12 is made Figure 2In the release posture shown in (a), the hair implanting hook part 3 is rotated 720 degrees while further retreating to allow the distal side hair part 111 to pass through the annular part 112, so that the pulling hook part 5 is lowered (hair material twisting action).

[0124] At this time, the annular portion 112 is preferably contracted by the annular portion passing motion so that the inner area (area of ​​the hole) becomes 1.05 times or more and 2 times or less the cross-sectional area of ​​the hair material 101 .

[0125] In addition, at this time, as the hair implanting hook part 3 retreats, the annular part 112 is further tightened and knotted.

[0126] Then, if Figure 6 As shown in (b), the distal side hair portion 111 is pulled in by the hair material pulling portion 8 and moved toward the downstream side of the conveying 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 side hair portion 111 located at the upstream side of the conveying direction T relative to the annular portion 112 with the posture change is dropped in by the hair material dropping portion 10 (dropping action).

[0127] According to the hair transplanting device 1 of this embodiment, the movement of the hair material 101 from the hair material supplying portion 6 can be restricted by the restriction mechanism 12. Therefore, when the hair material 101 is transplanted to the hair transplanting net 100 based on the hair transplanting hook portion 3, the movement of the hair material 101 from the hair material supplying portion 6 is restricted by the restriction mechanism 12, thereby making it difficult for the hair material 101 to fall from the hair material supplying portion 6 and making it difficult for the hair material 101 to be separated from the hair transplanting hook portion 3. As a result, the hair material 101 can be transplanted stably with respect to the hair transplanting net 100 compared with the past.

[0128] According to the hair implanting device 1 of this embodiment, the limiting mechanism 12 can fix a part of the hair material 101 to prevent the hair material 101 from falling off from the hair material supplying portion 6. Therefore, during the passing action of the annular portion, the hair material 101 can be prevented from accidentally falling off from the hair material supplying portion 6 along with the action of the hair implanting hook portion 3, and the hair material 101 can be stably implanted on the hair implanting net 100.

[0129] According to the hair implanting device 1 of the present embodiment, the hair material supplying portion 6 has the extraction hole 55 constituting the supply port for supplying the hair material 101 toward the lower side, and the limiting mechanism 12 can limit the position of the supply portion of the hair material 101 at a position that is opposite to the hair material supplying portion 6 in the vertical direction and is within a range where the shortest distance from the extraction hole 55 is 2 cm or less. That is, the limiting mechanism 12 can limit the position close to the hair material supplying portion 6, so that the hair material 101 is difficult to fall off from the hair material supplying portion 6.

[0130] According to the hair implanting device 1 of this embodiment, the limiting mechanism 12 includes the first clamping portion 80 and the second clamping portion 81 , and the clamping portions 80 and 81 clamp a portion of the hair material 101 , so that the movement of the hair material 101 can be easily limited.

[0131] According to the hair transplanting device 1 of this embodiment, the following operations are performed: a ring-shaped portion forming operation, in which a part of the middle portion of the hair material 101 is inserted from the first hole portion 120a across the second hole portion 120b by the hair transplanting hook portion 3 to form a ring-shaped portion 112 extending from the second hole portion 120b; and a ring-shaped portion tightening operation, in which the hair transplanting hook portion 3 hooks the proximal side hair portion 110 of the hair material 101 which is closer to the first end side than the first hole portion 120a and passes through the ring-shaped portion 112, and the proximal side hair portion 110 is moved in a direction away from the net wire 121 by the hair transplanting hook portion 3 to tighten the ring-shaped portion 112. Therefore, the ring-shaped portion 112 can be easily tightened, the knot of the ring-shaped portion 112 can be made smaller, and the hair material 101 can be transplanted with a better appearance relative to the hair transplanting net 100 than before.

[0132] According to the hair implanting device 1 of the present embodiment, the limiting mechanism 12 fixes a part of the proximal side hair portion 110 and a part of the distal side hair portion 111, respectively, so that during the annular portion tightening operation, the hair material 101 can be prevented from moving within the hair material supply portion 6 and the annular portion 112 of the hair material 101 can be stably tightened.

[0133] According to the hair implanting device 1 of the present embodiment, the hook portion 5 is pulled out to function as a tension applying component for hooking the portion of the hair material 101 that is closer to the second end side than the second hole portion 120b, i.e., the distal side hair portion 111, during the tightening action of the annular portion to apply tension to the hair material 101, so that the annular portion 112 is easier to tighten and the knot is easier to tighten.

[0134] In the above embodiment, the annular portion 112 is tightened by moving the implanted crochet needle portion 3 backward during the movement of the annular portion, but the present invention is not limited to this. For example, the implanted crochet needle portion 3 may be raised to tighten the annular portion 112. That is, the implanted crochet needle portion 3 may be moved in a direction away from the mesh wire 121 other than the front-rear direction X to tighten.

[0135] In the above embodiment, the annular portion 112 is tightened by pulling the hair implanting hook part 3 away from the mesh line 121 while the annular portion is in motion while the two end sides of the hair material 101 are fixed by the limiting mechanism 12. However, the present invention is not limited to this. Figure 7As shown in (a), while the two end sides of the hair material 101 are fixed by the limiting mechanism 12, the hook part 5 is pulled away from the mesh wire 121 (for example, downward), thereby tightening the annular part 112.

[0136] In this case, when the annular portion 112 is tightened to such an extent that the hair material 101 can pass through the inner side of the annular portion 112, as shown in FIG. Figure 7 As shown in (b) of FIG. 1 , the restricting mechanism 12 is brought into a released position, and the hair implanting hook part 3 is retracted while being rotated 720 degrees so that the distal side hair part 111 passes through the annular part 112 .

[0137] Alternatively, the annular portion 112 may be tightened by simultaneously or sequentially pulling the hair implanting hook portion 3 and the pulling hook portion 5 away from the mesh wire 121 while keeping the both end portions of the hair material 101 fixed by the limiting mechanism 12 .

[0138] In the above-mentioned embodiment, the limiting mechanism 12 clamps and fixes both sides of the proximal side hair portion 110 and the distal side hair portion 111, but the present invention is not limited thereto. It is also possible to fix only the hair portion of one side of the proximal side hair portion 110 and the distal side hair portion 111. For example, when the annular portion moves to make the implanted hair hook portion 3 retreat and the annular portion 112 is tightened, only the distal side hair portion 111 can be fixed, and when the pull-out hook portion 5 is moved to make the annular portion 112 tightened, only the proximal side hair portion 110 can be fixed.

[0139] In the above-mentioned embodiment, in the first hair material hooking action, the hook portion 51 of the hair implanting crochet needle part 3 is hooked on the proximal side hair portion 110, but the present invention is not limited thereto. In the first hair material hooking action, the hook portion 51 of the hair implanting crochet needle part 3 can also be hooked on the distal side hair portion 111.

[0140] In the above embodiment, the limiting mechanism 12 causes the clamping parts 80 and 81 to move relatively only in the width direction W to clamp the hair material 101, but the present invention is not limited thereto. The limiting mechanism 12 may cause the clamping parts 80 and 81 to move in the front-rear direction X in addition to the width direction W to clamp the hair material 101. Thus, the excess hair material 101 that cannot be used for hair transplantation and extends from the extraction hole 55 of the hair material supply part 6 can be clamped in the width direction W and moved in the front-rear direction X, and pulled out from the hair material supply part 6.

[0141] In the above embodiment, the limiting mechanism 12 is such that the guide portions 86 and 96 of the clamping portions 80 and 81 extend forward, but the present invention is not limited thereto. As long as the hair material 101 can be limited by the limiting mechanism 12, the extending direction of the guide portions 86 and 96 of the clamping portions 80 and 81 is not limited. For example, the guide portions 86 and 96 of the clamping portions 80 and 81 may extend backward and clamp the hair material 101 from the front side (the hair implanting hook portion 3 side).

[0142] The above-described embodiments may freely replace or add various components between the embodiments as long as they are included in the technical scope of the present invention.
