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 hair transplanting hook is hooked relative to the weft of the hair transplanting net supported by an eccentric wheel, and the eccentric wheel is rotated in this state to insert the hair transplanting hook between the adjacent holes sandwiching the weft of the hair transplanting net. Then, after the hair transplanting hook is hooked on the hair material, each hooked hair material is pulled, thereby enabling the hair material to pass through the adjacent holes and be transplanted relative to the hair transplanting net.

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

[0005] However, in the hair transplanting device of Patent Document 1, the hair transplanting net supported by the eccentric wheel inserts the hair transplanting hook into the hole to hook the weft thread in a state where tension is generated in the conveying direction. However, since the hair transplanting net has shrinkage, when the tension during transportation is high, the hair transplanting hook is passed through the hole of the hair transplanting net while the hole extends in the conveying direction. There is a problem that the hair transplanting hook contacts the weft thread and cannot pass through the hole of the hair transplanting net with high precision, or the weft thread is damaged. Summary of the invention

[0006] Therefore, an object of the present invention is to provide a hair transplanting device which allows the hair transplanting needle to pass through the holes of the hair transplanting net more easily than before and achieves higher hair transplanting accuracy.

[0007] One method 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; a hair implantation needle section for implanting the hair material supplied from the hair material supplying section relative to the hair implantation net; and an adjustment mechanism for adjusting the position of the holes of the hair implantation net in a direction intersecting with the conveying direction of the hair implantation net so that the hair implantation needle section passes through the holes of the hair implantation net, the adjustment mechanism having a supporting roller for supporting the hair implantation net, the supporting roller having a main body, a first engaging section capable of engaging with the hair implantation net, and a first force applying mechanism for applying force to the first engaging section in a direction away from the main body in the axial direction of the supporting roller.

[0008] According to this embodiment, there is an adjustment mechanism for adjusting the position of the holes of the hair transplanting net so that the hair transplanting needles can pass through the holes of the hair transplanting net. Therefore, it is easier to pass the hair transplanting needles through the holes of the hair transplanting net than before, and the accuracy of hair transplanting is higher.

[0009] According to this method, the first engaging portion that can engage with the hair implantation net can be forced in the axial direction of the supporting roller in a direction away from the main body by the first force applying mechanism, thereby applying axial tension to the hair implantation net, expanding the holes of the hair implantation net, and making it easier for the hair implantation needles to pass through the holes of the hair implantation net.

[0010] Preferably, the hair implantation needle part implants the hair material onto the hair implantation net on the support roller in a state where the support roller supports the hair implantation net.

[0011] In a preferred embodiment, the first engaging portion can engage with the wool implantation net in the axial direction of the support roller by being inserted through a hole of the wool implantation net, and an end of the first engaging portion in the insertion direction is a rounded end.

[0012] A preferred embodiment is that the supporting roller has a plurality of engaging pieces having the first engaging portion, and a spacing maintaining piece for maintaining the spacing between adjacent engaging pieces, and can engage with the wool implantation net in the axial direction by inserting the first engaging portion of each engaging piece into the corresponding hole of the wool implantation net.

[0013] In a preferred embodiment, at least one of the plurality of engagement pieces is rotatable in the circumferential direction of the support roller.

[0014] Preferably, the support roller has a second engaging portion, the first engaging portion engages with a first end side of the wool implantation net in the intersecting direction, and the second engaging portion engages with a second end side of the wool implantation net in the intersecting direction.

[0015] In a preferred embodiment, the support roller includes a second urging mechanism that urges the second engagement portion in a direction away from the first engagement portion in the axial direction of the support roller.

[0016] The above-mentioned aspects may be mutually dependent, part of the configuration may be cited, or part of the configuration may be replaced as long as they are included in the technical scope of the present invention.

[0044] Hereinafter, embodiments of the present invention will be described in detail.

[0045] The hair transplanting device 1 of the first embodiment of the present invention is an automatic hair transplanting device for automatically transplanting hair material 101 to a hair transplanting net 100. Figure 1 As shown, it includes an eccentric wheel portion (hereinafter, also referred to as the eccentric portion 2), a hair implanting hook portion 3, a pull-out hook portion 5, a hair material supply portion 6, a guide roller 7, a hair material pull-in portion 8, a hair material drop-in portion 10, and a conveying roller 11.

[0046] (Eccentric part 2)

[0047] like Figure 2 As shown, the eccentric portion 2 is an elongated body extending in the width direction W (axial direction L), and includes a support portion 20 and rotation shaft portions 21 a and 21 b.

[0048] The eccentric portion 2 is a rotation force conversion member that converts a rotational motion into a simple harmonic vibration by offsetting the rotation shaft portions 21 a and 21 b with respect to the central axis of the support portion 20 , and is a support roller that supports the wool implantation net 100 .

[0049] The supporting portion 20 is a portion for supporting the wool implanting net 100. Figure 2 As shown, it includes a main body 22, fixed shafts 23a, 23b, engaging portions 25a, 25b (first engaging portion, second engaging portion), urging mechanisms 26a, 26b (first urging mechanism, second urging mechanism), and fixing portions 27a, 27b.

[0050] In the axial direction L (intersecting direction (orthogonal direction) relative to the conveying direction T of the wool implantation net 100), the supporting part 20 applies force to the locking parts 25a, 25b outward relative to the main body 22 through the force-applying mechanisms 26a, 26b, thereby forming an adjustment mechanism, which adjusts the position of the hole 120 of the wool implantation net 100 so that the wool implantation hook part 3 passes through the hole 120 of the wool implantation net 100.

[0051] The main body portion 22 is a cylindrical portion extending along the axial direction L, and includes a recessed portion 28 in which a part of the outer circumference is recessed.

[0052] The recessed portion 28 is a cutout groove into which a part of the hair implanting hook portion 3 can be inserted, and is a concave groove formed entirely along the extending direction (axial direction L) of the main body portion 22 .

[0053] like Figure 2 As shown, the fixed shaft portions 23a, 23b are protruding shaft portions protruding outward from the end surface of the main body portion 22 in the axial direction L, and are connecting shaft portions that can axially support and connect the engaging portions 25a, 25b, the urging mechanisms 26a, 26b, and the fixed portions 27a, 27b, respectively.

[0054] The fixed shaft portions 23a and 23b include fastening portions (not shown) that can be fastened to the fixing portions 27a and 27b at the front end portions in the protruding direction.

[0055] like Figure 4 As shown, the engaging portions 25 a and 25 b are inserted into the holes 120 of the hair implantation net 100 and are engageable with the net wires 121 .

[0056] like Figure 3 As shown, the engaging portions 25 a and 25 b include a plurality of engaging pieces 30 and a plurality of spacing maintaining pieces 31 , which are overlapped in the axial direction L.

[0057] The engaging piece 30 is an annular plate-like piece that can be mounted around the fixed shaft portions 23a and 23b. Figure 3 As shown in (b) of FIG. 8 , the base portion 35 , the protrusion 36 , and the insertion hole 37 are provided.

[0058] The base portion 35 is an annular portion, and when viewed from the axial direction L, the outer diameter thereof is equal to the minimum surrounding circle diameter of the main body portion 22 .

[0059] The convex part 36 is a cylindrical protrusion protruding radially from the outer surface of the base part 35, and the front end is rounded. That is, the front end of the convex part 36 is not pointed, and it is difficult to damage it even if it contacts the hair planting net 100.

[0060] The projections 36 are arranged at intervals in the circumferential direction of the fixed shaft portions 23a and 23b.

[0061] The insertion hole 37 is a through hole that penetrates the central portion of the base portion 35 in the thickness direction, and the fixed shaft portions 23 a and 23 b can be inserted therethrough.

[0062] like Figure 3 As shown, the interval maintaining piece 31 is an annular plate-like piece that can be mounted around the fixed shaft portions 23 a , 23 b and is interposed between the engaging pieces 30 , 30 adjacent to each other in the axial direction L to maintain the interval between the engaging pieces 30 , 30 .

[0063] The space maintaining piece 31 includes a base portion 38 and an insertion hole 39 .

[0064] The base portion 38 is an annular portion, and when viewed from the axial direction L, the outer diameter thereof is equal to the outer diameter of the base portion 35 .

[0065] The insertion hole 39 is a through hole that penetrates the central portion of the base portion 38 in the thickness direction and allows the fixed shaft portions 23 a and 23 b to be inserted therethrough.

[0066] The engagement portions 25 a and 25 b are spaced evenly in the axial direction L by sandwiching the interval maintaining piece 31 with the engagement pieces 30 , and the intervals between the adjacent projections 36 and 36 in the axial direction L are also equal.

[0067] The engaging parts 25a and 25b are such that the inner diameter of the insertion hole 37 of each engaging piece 30 and the inner diameter of the insertion hole 39 of each spacing maintaining piece 31 are larger than the outer diameter of the fixed shaft parts 23a and 23b, and each engaging piece 30 and each spacing maintaining piece 31 can rotate in the circumferential direction of the fixed shaft parts 23a and 23b.

[0068] like Figure 2 As shown in the figure, the urging mechanism 26a, 26b is an urging member that urges the engaging portions 25a, 25b toward the outside of the axial direction L, and specifically, is an elastic member such as a coil spring that can be axially supported by the fixed shaft portions 23a, 23b. That is, the urging mechanism 26a, 26b can be elastically deformed, and the engaging portions 25a, 25b are always urged toward the outside of the axial direction L by their restoring force.

[0069] The fixing portions 27 a and 27 b are restricting portions that restrict the outer movement of the engaging portions 25 a and 25 b in the axial direction L against the urging force of the urging mechanisms 26 a and 26 b .

[0070] The fixing portions 27 a and 27 b are composed of a pair of clamping portions 32 and 33 .

[0071] like Figure 3 As shown in FIG. 2 ( a ), the inner clamping portion 32 includes a clamping body portion 40 and an insertion hole 41 .

[0072] The clamp body portion 40 is an annular portion, and when viewed from the axial direction L, the outer diameter thereof is equal to the minimum surrounding circle diameter of the body portion 22 .

[0073] The insertion hole 41 is a through hole that penetrates the central portion of the clamp body 40 in the thickness direction, and the fixed shaft portions 23 a and 23 b can be inserted therethrough.

[0074] The outer clamping portion 33 has a clamping body portion 42 and a fastening hole 43 .

[0075] The clamp body portion 42 is a cylindrical portion, and when viewed from the axial direction L, the outer diameter is equal to the minimum surrounding circle diameter of the body portion 22 .

[0076] The fastening hole 43 is a bottomed hole whose bottom is the outer side in the axial direction L of the central portion of the clamp body portion 42 , and can be fastened to the fixed shaft portions 23 a and 23 b .

[0077] The fixing portions 27a and 27b integrally fix the outer clamping portion 33 to the fixed shaft portions 23a and 23b, and the inner clamping portion 32 and the outer clamping portion 33 clamp the engaging portions 25a and 25b, thereby restricting the engaging portions 25a and 25b from moving outward in the axial direction L.

[0078] like Figure 2 , Figure 3 As shown in FIG. 2( a ), the rotating shaft portions 21 a and 21 b are shaft portions that serve as the rotation center of the eccentric portion 2 .

[0079] The rotating shaft portions 21 a and 21 b extend outward in the axial direction L from the fixing portions 27 a and 27 b of the main body portion 22 , and the central axes are provided at positions offset from the central axes of the fixing shaft portions 23 a and 23 b .

[0080] The eccentric portion 2 can change its posture between the first posture and the second posture by rotating about the rotation shaft portions 21 a and 21 b.

[0081] like Figure 5 As shown in (a) of FIG. 1 , the first posture is an opposing posture in which the recessed portion 28 of the main body 22 is located on the hair implantation hook portion 3 side and faces the hair implantation hook portion 3 .

[0082] like Figure 5 As shown in (b) of FIG. 1 , the second posture is a vertical posture in which the recessed portion 28 of the main body 22 is located on the hair material supplying portion 6 side and faces upward.

[0083] (Hair transplanting crochet part 3)

[0084] The hair transplanting hook part 3 is a hair transplanting needle part for transplanting the hair material 101 to the hair transplanting net 100, and is a rod-shaped body with a hook-shaped tip.

[0085] like Figure 1 As shown in FIG. 1 (a), the hair implantation hook needle part 3 is a latch hook needle including a needle shaft part 50, a hook part 51, and a latch part 52.

[0086] (Pull out the hook part 5)

[0087] The hook pulling unit 5 is a hook that pulls out the hair material 101 from the hair material supply unit 6 .

[0088] The hook needle part 5 is a rod-shaped body with a hook claw at the front end. Figure 1 As shown in (b) of FIG. 8 , the needle shaft portion 60 and the hook portion 61 are provided.

[0089] (Hair material supply unit 6)

[0090] 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 in (a) of FIG. 1 , a take-out hole 55 for taking out and supplying the stored hair material 101 is provided at the bottom.

[0091] (Guide Roller 7)

[0092] 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.

[0093] (Hair material pulling-in portion 8)

[0094] 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 .

[0095] (Hair material falling portion 10)

[0096] 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 .

[0097] (Conveyor roller 11)

[0098] 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.

[0099] (Planting net 100)

[0100] like Figure 4 As shown, the hair implantation net 100 is a stretchable net formed of a plurality of net wires 121 in a mesh shape and has a plurality of holes 120 .

[0101] 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.

[0102] The hole 120 is a hexagonal hole in a plan view, and each side is formed by a mesh wire 121 .

[0103] (Hair Materials 101)

[0104] The hair material 101 is a linear body that is implanted on the hair implantation net 100 .

[0105] As the hair material 101, artificial hair made of resin fiber or the like, human hair, animal hair, or the like can be used.

[0106] The hair material 101 of this embodiment is used as a hair bundle by bundling a plurality of hairs.

[0107] 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 portion 22 is located on the hair implantation hook needle portion 3 side and faces the hair implantation hook needle portion 3 side.

[0108] 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 .

[0109] 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.

[0110] The eccentric portion 2 is as follows Figure 2 As shown in FIG. 1 , the main body 22 is located between the engaging portions 25a and 25b in the width direction W. Figure 2 , Figure 4 As shown, the hair implantation net 100 is suspended across the main body 22 and the engaging parts 25a and 25b.

[0111] The eccentric portion 2 is such that, in the axial direction L, the protrusion 36 of the first engaging portion 25a engages with the hole 120 on the first end side of the wool implantation net 100, and the protrusion 36 of the second engaging portion 25b engages with the hole 120 on the second end side (the end opposite to the first end) of the wool implantation net 100.

[0112] The eccentric part 2 is urged by the urging mechanism 26a, 26b so that the engaging parts 25a, 25b engaged with the wool net 100 in the width direction W are separated from the main body 22, and the tension is adjusted so that the position of the hole 120 of the wool net 100 passes through the predetermined position. Figure 4 As shown, in the eccentric portion 2 , a part of the protrusion 36 of the engaging portion 25 a , 25 b is inserted into the hole 120 of the hair embedding net 100 , and the hair embedding net 100 is urged in the width direction W by the urging means 26 a , 26 b via the protrusion 36 .

[0113] So, like Figure 4 As shown, the eccentric portion 2 is inserted into the hole 120 of the wool implanting net 100 through the convex portion 36, thereby the convex portion 36 expands the hole 120 of the wool implanting net 100 in the width direction W, and the position in the width direction W is adjusted so that the hole 120 of the wool implanting net 100 is located in the projection portion P of the moving direction of the wool implanting hook needle portion 3 (the projection surface of the axial direction L of the needle shaft portion 50).

[0114] like Figure 1 As shown in (a) of FIG. 1 , 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 22 in the front-back direction X.

[0115] 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).

[0116] 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 .

[0117] Next, the hair transplanting operation of the hair transplanting device 1 of this embodiment will be described.

[0118] First, the hair implanting action of the hair implanting device 1 is as follows: Figure 5 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).

[0119] At this time, if Figure 5As 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 and a distal side hair part 111 based on the engagement part (turned part) engaged with the hook part 61 of the pull-out hook part 5.

[0120] Furthermore, in actions different from the hair material pulling action, e.g. Figure 5 As shown by the arrow in (a), the hair-implanting crochet needle part 3 is advanced toward the eccentric part 2, and the hook part 51 of the hair-implanting crochet needle part 3 is arranged in the recess 28 of the eccentric part 2 through the hole 120a of the hair-implanting net 100 on the eccentric part 2. Then, the hair-implanting crochet needle part 3 is retreated from the recess 28 of the eccentric part 2 and raised (net hook hanging action).

[0121] At this time, the hair embedding hook part 3 retreats and rises to hook the mesh thread 121 as the weft thread forming the edge of the hole 120a of the hair embedding net 100 on the eccentric part 2 through the hook part 51 and lift it upward.

[0122] Next, in the state that the hair implanting hook needle part 3 is hooked on the mesh line 121, as Figure 5 As shown by the arrow in (b), the eccentric portion 2 is rotated 90 degrees in the forward direction R1 to change the posture from the first posture to the second posture, so that the hook portion 51 of the hair implanting hook needle portion 3 extends from the recess 28 (eccentric wheel rotation action).

[0123] 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.

[0124] Then, if Figure 6 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).

[0125] 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 holes 120a and 120b adjacent to each other across the net line 121 of the hair implantation net 100.

[0126] Then, if Figure 6 As shown by the arrow in (a), the hair implanting hook part 3 is retreated and the pulled-out hook part 5 is returned to the original reference position, and the hair implanting hook part 3 is rotated 90 degrees in the circumferential direction so that the hook part 51 faces upward and is pulled out from the hair implanting net 100 (hair material pulling action).

[0127] At this time, the latch portion 52 of the hair implanting hook portion 3 is closed by the mesh line 121 of the hair implanting net 100, and the hair implanting hook portion 3 is pulled out from the hair implanting net 100 while grasping the proximal side hair portion 110 of the hair material 101. In addition, the middle portion of the proximal side hair portion 110 passes through the holes 120a and 120b of the hair implanting net 100, and forms an annular portion 112 and is exposed from the hair implanting net 100 to the hair implanting hook portion 3 side.

[0128] Then, if Figure 6 As 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 6 As shown by the arrow in (b), the hair implanting hook part 3 is raised and deviated in the axial direction L of the eccentric part 2 (twisting action of the hair material).

[0129] Then, if Figure 7 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 toward the axial direction L of the eccentric part 2 and returns 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).

[0130] Then, if Figure 7 As shown in (b), the hair implanting hook part 3 is further retreated and rotated 90 degrees to a posture where 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 (hair material pulling action).

[0131] 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 .

[0132] Next, the hook hook part 5 is raised and located at a position offset from the position of the hair material 101, thereby releasing the engagement between the hook hook part 5 and the hair material 101.
