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 attaching a hair material for hair implanting 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 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 thread on the distal side of the hair material, in a state where the hair material can move freely from the stocker, the hooked thread on the distal side is passed through the loop portion and pulled out, so that it is possible to implant hair on the hair implanting net.

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in order to continuously implant hair materials onto a hair implanting net in the hair implanting device of Patent Document 1, at the start of the first operation, the planned insertion position where the first crochet hook is inserted needs to overlap with the holes of the hair implanting net. In the hair implanting device of Patent Document 1, the deflection of the hair implanting net formed by the 1 / 4 rotation operation of the eccentric in the fifth operation is absorbed by the turning of the eccentric in the seventeenth operation.

[0005] However, when the hair implant net has elasticity, in the rotation of the eccentric in the 17th operation, the deflection cannot be absorbed, or the hair implant net is deformed due to the self-weight of the hair material and the hair implant net tilts, and the planned insertion position may not overlap with the holes of the hair implant net. In such a case, in the subsequent hair implanting operation, the first crochet needle may contact the weft of the hair implant net, and there is a possibility that the hair material cannot be implanted into the hair implant net.

[0006] Therefore, an object of the present invention is to provide a hair implanting device that can stably implant a hair material into a hair implant net as compared with the prior art.

Means for Solving the Problems

[0007] One aspect of the present invention for solving the above problems is a net conveying unit that conveys a hair implant net having a group of through holes in which a plurality of through holes are linearly arranged in the width direction, a hair material supply unit that supplies a hair material from the middle part of the hair material toward the hair implant net side, a hair implanting needle unit that attaches and implants a part of the middle part of the hair material supplied from the hair material supply unit to the hair implant net, and an angle of a straight line connecting the central axes of the group of through holes is in the range of 88 degrees or more and 92 degrees or less with respect to the conveying direction of the hair implant net, and a drawing means for drawing at least the hair implant net to the upstream side or the downstream side in the conveying direction. It is a hair implanting device provided with.

[0008] According to this aspect, since at least the hair implant net is drawn in by the drawing means so that the hair implant net is substantially not tilted, the hair implant net is not bent, and it is easy to pass the hair implanting needle part through the hole continuously, and the hair material can be stably implanted into the hair implant net as compared with the prior art.

[0009] By the way, in the hair implanting device of Patent Document 1, after implanting hair materials onto the implanting net, the hair materials are dropped downward by a thread dropping bar for hair styling. However, the hair materials after hair styling are in a state where they can move freely. After hair styling, due to factors such as static electricity, when the thread dropping bar rises, a part of the hair materials may follow the thread dropping bar, and the hair materials may overlap the implanting part on the upstream side. When the hair materials overlap the implanting part, the movement of the implanting needles may be obstructed by the hair materials, and it may not be possible to continue implanting hair.

[0010] Therefore, a preferred aspect is that the pulling-in means pulls in the hair materials implanted by the implanting net and the implanting needle part to the downstream side in the conveying direction.

[0011] According to this aspect, the hair materials already implanted on the implanting net do not flow to the upstream side in the conveying direction, and it is less likely to obstruct the subsequent implanting of hair materials onto the implanting net.

[0012] A preferred aspect is that it has a sending-out means for sending out the hair materials implanted by the implanting needle part to the downstream side in the conveying direction.

[0013] A preferred aspect is that the sending-out means can send out the hair materials implanted by the implanting needle part to the downstream side without contact.

[0014] A preferred aspect is that the pulling-in means has a first clamping roll, a second clamping roll, and a moving means for relatively moving the first clamping roll with respect to the second clamping roll. The pulling-in means brings the first clamping roll close to the second clamping roll to clamp at least the implanting net, and by rotating the first clamping roll and / or the second clamping roll, the implanting net is pulled in to the upstream side or the downstream side in the conveying direction.

[0015] A preferred aspect has a first rotating roll and a second rotating roll. The first clamping roll rotates by transmitting the respective rotational forces of the first rotating roll and the second rotating roll. In the axial direction of the first clamping roll, the first rotating roll contacts the first end side to transmit the rotational force, and the second rotating roll contacts the second end side to transmit the rotational force.

[0016] A preferred aspect has a first rotating roll and a second rotating roll. The first clamping roll rotates by transmitting the respective rotational forces of the first rotating roll and the second rotating roll. The first rotating roll and the second rotating roll are in contact with the first clamping roll outside the hair implanting net in the axial direction of the first clamping roll.

[0017] A preferred aspect is that the first clamping roll has an adjustment axis in a direction intersecting the axial direction of the first clamping roll and facing the second clamping roll, and the first clamping roll is rotatable in the circumferential direction around the adjustment axis.

[0018] A preferred aspect is that the adjustment axis is outside the hair implanting net in the axial direction of the first clamping roll.

[0019] A preferred aspect has a support roll that supports the hair implanting net with a main body portion. The support roll has an axis of the main body portion eccentric with respect to the rotation axis, and the hair implanting needle portion implants the hair material onto the hair implanting net using the rotation of the support roll.

[0020] As long as the above-described aspects are within the technical scope of the present invention, between the respective aspects, they can be made mutually dependent, a part of the configuration can be cited, or a part of the configuration can be replaced.

Effects of the Invention

[0021] According to the present invention, the hair material can be stably implanted into the hair implanting net as compared with the prior art.

Mode for Carrying Out the Invention

[0023] Hereinafter, embodiments of the present invention will be described in detail.

[0024] The hair implanting device 1 according to the first embodiment of the present invention is an automatic hair implanting device that automatically implants hair materials 101 into a hair implanting net 100. As shown in FIG. 1, it includes an eccentric part (hereinafter, also simply referred to as the eccentric part 2) (support roll), a hair implanting crochet part 3 (hair implanting needle part), a drawing crochet part 5, a hair material supply part 6, a guiding roll 7, a hair material drawing-in part 8, a hair material dropping part 10, a conveying roll 11 (net conveying part), a drawing-in means 12, and a sending-out means 15.

[0025] (Eccentric part 2) As shown in FIG. 2, the eccentric part 2 is an elongated body extending in the width direction W (axial direction L), and includes a main body part 20 and rotary shaft parts 21a and 21b. The eccentric part 2 is a rotational 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 the rotational motion into a single vibration, and is a support roll for supporting the hair implanting net 100.

[0026] The main body part 20 is a columnar part extending in the axial direction L, and has a concave part 28 in which a part of the outer circumference is recessed. The concave part 28 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 (axial direction L) of the main body part 20.

[0027] The rotary shaft parts 21a and 21b are shaft parts that serve as the rotation centers 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 axial direction L, and their central axes are provided at positions displaced from the central axis of the main body part 20.

[0028] The eccentric part 2 can change its posture between a first posture and a second posture by rotating about the rotary shaft parts 21a and 21b. The first posture is an opposing posture in which the concave part 28 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. 5(a). The second posture is a vertical posture in which the concave part 28 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. 5(b).

[0029] (Hair implanting crochet needle part 3) The hair implanting crochet needle 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 shape. As shown in Fig. 1, the hair implanting crochet needle part 3 is a latch hook needle including a needle shaft part 50, a hook part 51, and a latch part 52.

[0030] (Pull-out crochet needle part 5) The pull-out crochet needle part 5 is a crochet needle for pulling out the hair material 101 from the hair material supply part 6. The pull-out crochet needle part 5 has a rod-shaped body with a hooked claw at the tip, and as shown in Fig. 1, it includes a needle shaft part 60 and a hook part 61.

[0031] (Hair material supply part 6) The hair material supply part 6 is a hair material storage part for storing the hair material 101 to be implanted into the hair implanting net 100. As shown in Fig. 1, a take-out hole 55 is provided at the bottom for taking out and supplying the stored hair material 101.

[0032] (Guide roll 7) As shown in Fig. 1(b), the guide roll 7 has a groove part 70 on a part of its outer peripheral surface. A part of the hair material 101 pulled out from the hair material supply part 6 by the pull-out crochet needle part 5 passes through the groove part 70, so that the position in the axial direction L is adjusted to fall within a predetermined range.

[0033] (Hair material drawing-in part 8) The hair material drawing-in part 8 is a drawing-in bar for drawing in the hair material 101 pulled out from the hair material supply part 6 by the pull-out crochet needle part 5 to the upstream side in the conveying direction T from the hair implanting position of the hair implanting net 100.

[0034] (Hair material dropping part 10) The hair material dropping part 10 is a dropping bar for dropping the hair material 101 pulled out from the hair material supply part 6 by the pull-out crochet needle part 5 to the lower side than the hair implanting position of the hair implanting net 100.

[0035] (Conveying roll 11) The conveying roll 11 is a support roll that supports the flocking net 100 so that the flocking net 100 passes over the eccentric part 2, and is a net conveying part that conveys the flocking net 100 in the conveying direction T by rotating.

[0036] (Pull-in means 12) The pull-in means 12 is a part that pulls in at least the flocking net 100 to the downstream side in the conveying direction T so as to align the center position C1 of a specific hole part 120 of the flocking net 100 shown in FIG. 3 with the position of the projection plane in the front-rear direction X of the flocking hook needle part 3 (the planned insertion position 122). As shown in FIG. 2, the pull-in means 12 includes a first clamping roll 80, a second clamping roll 81, and a drive unit 82.

[0037] The first clamping roll 80 is a driven roll whose rotation axis extends in the width direction W (axial direction L) and rotates in the circumferential direction about the rotation axis by receiving the power of the drive unit 82. The first clamping roll 80 is movable so as to approach and separate relatively from the second clamping roll 81 by a moving means (not shown), and can clamp at least the flocking net 100 with the second clamping roll 81 shown by the solid line in FIG. 2, and can move between a non-contact position away from the flocking net 100 shown by the virtual line in FIG. 2 and not in contact with the flocking net 100. As shown in FIG. 4, the first clamping roll 80 has an adjustment axis L2 in the direction intersecting the axial direction L1 of the first clamping roll 80 and facing the second clamping roll 81, and can rotate about the adjustment axis L2. That is, the first clamping roll 80 can move with a vertical direction component about the adjustment axis L2. The first clamping roll 80 of the present embodiment can be rotated manually from -3 degrees to 3 degrees about the adjustment axis L2, and the rotation angle is restricted by a restricting part. The position of the adjustment axis L2 of the first clamping roll 80 is preferably outside the axial direction L of the flocking net 100 in the flocking operation and at a position not in contact with the flocking net 100. The material of the first clamping roll 80 is not particularly limited, and urethane resin, ethylene propylene rubber, etc. can be used. The first clamping roll 80 preferably has a hardness of 20 or more and 30 or less as measured by a type A durometer according to JIS K 6253-3:2012 (ISO 7619-1). By doing so, even if the thickness increases as the hair material 101 is implanted into the implant net 100, it is possible to suppress the pulling of the implant net 100 by the rotation of the first clamping roll 80.

[0038] The second clamping roll 81 is paired with the first clamping roll 80 and is a roll that clamps the implant net 100 and the hair material 101 together with the first clamping roll 80. The second clamping roll 81 may be a driving roll having a power source and rotatable by the power source, or may be an idle roll without a power source.

[0039] The drive unit 82 transmits a rotational force to the first clamping roll 80 and rotates the first clamping roll 80. As shown in FIG. 2, the drive unit 82 is composed of a plurality of rotating rolls 90, 91. Each rotating roll 90, 91 is a driving roll provided with a power source such as a servo motor and rotatable by the power source. That is, the drive unit 82 can transmit the rotational force of the rotating rolls 90, 91 to the first clamping roll 80 directly or via other members, and rotate the first clamping roll 80.

[0040] (Delivery means 15) The delivery means 15 is a part that sends out the hair material 101 implanted in the implant net 100 to the downstream side in the transport direction T, and is also an aligning means for aligning the hair material 101 implanted in the implant net 100. The delivery means 15 of the present embodiment sends out the hair material 101 implanted in the implant net 100 to the downstream side in the transport direction T in a non-contact manner. Specifically, as shown in FIG. 1, the delivery means 15 has an air outlet 95, and blows air from the air outlet 95 onto the hair material 101 implanted on the implanting net 100, and is a blowing means for sending out the hair material 101 implanted on the implanting net 100 to the downstream side in the conveying direction T. The delivery means 15 may blow air containing ions for removing static electricity. By doing so, the static electricity charged on the surface of the hair material 101 can be neutralized by the ions and made electrically neutral.

[0041] (Implanting net 100) As shown in FIG. 3, the implanting net 100 is an expandable and contractible net formed in a mesh shape by a plurality of net wires 121, and has a plurality of hole portions 120 (through holes, through hole groups). The implanting net 100 of the present embodiment has a honeycomb structure and can expand and contract in the conveying direction T and the width direction W. The hole portion 120 is a hexagonal hole in plan view, and each side is formed by the net wire 121. The hole portion 120 is a through hole penetrating in the thickness direction, forms a group of through holes arranged in a row in the width direction W, and the group of through holes is arranged side by side in the conveying direction T.

[0042] (Hair material 101) The hair material 101 is a filamentous body implanted on the implanting net 100. As the hair material 101, artificial hair, human hair, animal hair, etc. composed of resin fibers or the like can be used. The hair material 101 of the present embodiment is bundled into a plurality and used as a hair bundle.

[0043] Subsequently, the positional relationship of each part of the implanting device 1 of the present embodiment will be described. Regarding the eccentric portion 2, with reference to the first posture shown in FIG. 1 where the concave portion 28 of the main body portion 20 is located on the side of the implanting crochet needle portion 3 and faces the implanting crochet needle portion 3 side.

[0044] As shown in FIG. 1, in the implanting device 1, the implanting net 100 is suspended on the eccentric portion 2, the conveying roll 11, and the second clamping roll 81. The eccentric part 2 has the rotary shaft parts 21a and 21b pivotally supported thereon and is rotatable in the circumferential direction about the rotary shaft parts 21a and 21b.

[0045] As shown in FIG. 1, the hair implanting crochet part 3 is in a horizontal posture extending in the horizontal direction, and the hook part 51 faces the concave part 28 of the main body part 20 in the front-rear direction X. The pulling-out crochet part 5 has the hook part 61 at the tip positioned on the upper side and is in a vertical posture extending in the vertical direction, and faces the take-out hole 55 of the hair material supply part 6 in the height direction Y (vertical direction). The hair material drawing-in part 8 is located below the hair material supply part 6 and above the eccentric part 2 in the height direction Y.

[0046] As shown in FIG. 1, the drawing-in means 12 has the first clamping roll 80 and the second clamping roll 81 facing each other with the hair implanting net 100 clamped therebetween. As shown in FIG. 3(b), the rotary rolls 90 and 91 of the drive unit 82 pass through the center of the hair implanting net 100 in the width direction W and are in a left-right symmetric (mirror image) relationship with respect to the orthogonal plane of the first clamping roll 80 in the width direction W (axial direction L). As shown in FIG. 3(b), the rotary rolls 90 and 91 are outside the hair implanting net 100 in the width direction W and are in contact with the hair implanting net 100 at positions substantially equidistant from the center position C2 (the center position of the hair implanting net 100 in the width direction W) of the first clamping roll 80. That is, the difference between the distance D1 between the first rotary roll 90 and the center position C2 in the width direction W and the distance D2 between the second rotary roll 91 and the center position C2 in the width direction W is 5% or less of the width of the hair implanting net 100, and in this embodiment, it is equal to the distance D2 between the second rotary roll 91 and the center position C2 in the width direction W. In the drive unit 82, a part of the outer peripheral surfaces of the rotary rolls 90 and 91 is in contact with the outer peripheral surface of the first clamping roll 80, and the rotational force of the rotary rolls 90 and 91 is transmitted to the first clamping roll 80 through the contact part, enabling the first clamping roll 80 to be rotated passively.

[0047] The delivery means 15 has a blowout port 95 facing the downstream side in the conveyance direction T from the planned insertion position 122 of the flocking net 100 and facing the flocking net 100 side.

[0048] Subsequently, the flocking operation of the flocking device 1 of the present embodiment will be described.

[0049] First, as a preparatory step before performing the flocking operation of the flocking device 1, the first clamping roll 80 is rotated to align it so as to be parallel to the axial direction L3 of the second clamping roll 81, and the flocking net 100 is adjusted to be linearly clamped between the first clamping roll 80 and the second clamping roll 81, and then the flocking operation of the flocking device 1 is performed.

[0050] The flocking operation of the flocking device 1 is, as shown in Fig. 5(a), after raising the drawing crochet part 5 and hooking it on 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, and the drawing crochet part 5 is displaced in the axial direction L of the eccentric part 2 from the reference position (hair material drawing operation).

[0051] At this time, the hair material 101 in the hair material supply part 6 is drawn out in a "V" shape by the hook part 61 of the drawing crochet part 5 as shown in Fig. 5(a), and the engagement part (hooking part) with the hook part 61 of the drawing crochet part 5 is at a position lower than the apex of the eccentric part 2. Also, the hair material 101 is divided into a proximal hair part 110 and a distal hair part 111 with the engagement part (folding part) with the hook part 61 of the drawing crochet part 5 as a reference.

[0052] Also, in an operation different from the hair material drawing operation, as shown by the arrow in Fig. 5(a), the flocking crochet part 3 is advanced toward the eccentric part 2, and the hook part 51 of the flocking crochet part 3 is passed through the hole part 120a of the flocking net 100 on the eccentric part 2 and arranged in the concave part 28 of the eccentric part 2. Then, as shown in Fig. 5(b), the flocking crochet part 3 is retracted and raised from the concave part 28 of the eccentric part 2 (net hooking operation).

[0053] At this time, the implanting crochet portion 3 hooks the net yarn 121, which is a weft yarn forming the edge of the hole portion 120a of the implanting net 100 on the eccentric portion 2, by retreating and rising, and lifts it upward with the hook portion 51. That is, the implanting crochet portion 3 hooks the hook portion 51 on the net yarn 121 extending in the crossing direction (orthogonal direction in this embodiment) with respect to the conveying direction T.

[0054] Subsequently, with the implanting crochet portion 3 hooked on the net yarn 121, as shown by the arrow in FIG. 5(b), the first clamping roll 80 is separated from the implanting net 100, and the eccentric portion 2 is rotated 90 degrees in the forward direction R1 to the second posture, and the hook portion 51 of the implanting crochet portion 3 is taken out from the concave portion 28 (eccentric rotation operation).

[0055] At this time, with the rotation of the eccentric portion 2, the implanting crochet portion 3 is inserted across the adjacent hole portions 120a and 120b while sandwiching the net yarn 121 of the implanting net 100. Also, as shown in FIG. 5(b), the first clamping roll 80 is in a non-contact position where it is separated from the implanting net 100 to such an extent that it does not contact the implanting net 100 in the state where the eccentric portion 2 is rotated to the second posture.

[0056] Subsequently, as shown in FIG. 6(a), the implanting crochet portion 3 is further advanced and the implanting crochet portion 3 is rotated 90 degrees in the circumferential direction, and the drawing crochet portion 5 is moved so that the hook portion 51 of the implanting crochet portion 3 catches on the proximal hair portion 110 (first hair material catching operation).

[0057] At this time, with the advancement of the implanting crochet portion 3, a part of the needle shaft portion 50 is inserted across the adjacent hole portions 120a and 120b while sandwiching the net yarn 121 of the implanting net 100.

[0058] Subsequently, as shown by the arrow in FIG. 6(a), the implanting crochet portion 3 hooked on the proximal hair portion 110 is retracted, the drawing crochet portion 5 is returned to the original reference position, and the implanting crochet portion 3 is further rotated 90 degrees in the circumferential direction so that the hook portion 51 faces upward, pulled out from the implanting net 100, and an annular portion 112 is formed at the proximal hair portion 110 (annular portion forming operation).

[0059] At this time, the latch portion 52 of the implanting crochet portion 3 is closed by the net yarn 121 of the implanting net 100, and the implanting crochet portion 3 is pulled out from the implanting net 100 while grasping the proximal hair portion 110 of the hair material 101. Further, the intermediate portion of the hair material 101 passes through the hole portions 120a and 120b of the implanting net 100, forms an annular portion 112, and the annular portion 112 is exposed from the hole portion 120a of the implanting net 100 toward the implanting crochet portion 3 side.

[0060] Subsequently, as shown in FIG. 6(b), the implanting crochet portion 3 is rotated 360 degrees to twist the annular portion 112 of the hair material 101, and the implanting crochet portion 3 is lifted as shown by the arrow in FIG. 6(b) and shifted in the axial direction L of the eccentric portion 2 (hair material twisting operation).

[0061] Subsequently, as shown in FIG. 7(a), the implanting crochet portion 3 is advanced beyond the proximal hair portion 110, the implanting crochet portion 3 is slightly retracted and rotated 90 degrees in the circumferential direction, the implanting crochet portion 3 is shifted in the axial direction L of the eccentric portion 2 and returned to a position overlapping the hair material 101, and the tip of the implanting crochet portion 3 is hooked on the proximal hair portion 110 of the hair material 101 (second hair material hooking operation).

[0062] Subsequently, as shown in FIG. 7(b), the implanting crochet portion 3 is further retracted and rotated 90 degrees so that the hook portion 51 faces upward, and the engaging portion of the hair material 101 with the implanting crochet portion 3 is passed through the annular portion 112 (annular portion passing operation).

[0063] At this time, the latch portion 52 of the implanting crochet portion 3 is closed by the annular portion 112 of the implanting net 100.

[0064] Subsequently, the pulling-out crochet portion 5 is lifted and shifted to a position deviated from the position of the hair material 101 to release the engagement between the pulling-out crochet portion 5 and the hair material 101. As shown in FIG. 8(a), the implanting crochet portion 3 is further retracted while being rotated 720 degrees to pass the distal hair portion 111 through the annular portion 112, and the pulling-out crochet portion 5 is lowered (hair material twisting operation).

[0065] Subsequently, as shown in Fig. 8(b), the distal hair portion 111 is drawn in by the hair material drawing-in portion 8 and flowed downstream in the conveying direction T, the eccentric portion 2 is rotated 90 degrees in the reverse direction R2 to change the posture from the second posture to the first posture, and along with the posture change, the distal hair portion 111 located upstream in the conveying direction T with respect to the annular portion 112 is dropped by the hair material dropping portion 10 (dropping operation).

[0066] Subsequently, as shown by the arrow in Fig. 9(a), the hair material 101 implanted in the hair implanting net 100 is sent out non-contact downstream in the conveying direction T by the sending means 15 and aligned (alignment step). Specifically, the sending means 15 blows air so that the distal end sides of the proximal hair portion 110 and the distal hair portion 111 are located downstream in the conveying direction T for alignment.

[0067] Subsequently, as shown in Fig. 9(b), the first clamping roll 80 of the drawing-in means 12 is moved toward the second clamping roll 81, and the proximal hair portion 110 and the distal hair portion 111 aligned in the alignment step are clamped by the first clamping roll 80 and the second clamping roll 81 together with the hair implanting net 100, and the first clamping roll 80 is rotated by rotating each rotating roll 90, 91 of the drive unit 82 to draw in the hair implanting net 100, the proximal hair portion 110, and the distal hair portion 111 downstream (drawing-in step).

[0068] At this time, the hair implanting net 100 is drawn in by the first clamping roll 80 and the second clamping roll 81 together with both the proximal hair portion 110 and the distal hair portion 111, and tension is applied. Here, as shown in Fig. 3(b), the distance D1 between the first rotating roll 90 and the center position C2 in the width direction W is equal to the distance D2 between the second rotating roll 91 and the center position C2 in the width direction W, and since they rotate with the same output, a rotational force is evenly applied to the hair implanting net 100, and as shown in Fig. 3(a), the center positions C1 of the hole portions 120 are arranged in a straight line in the width direction W, and the insertion planned positions 122 facing the hair implanting hook needle portion 3 are substantially aligned in the width direction W. That is, in the hair implanting net 100, the straight line CL1 connecting the center positions C1 of the respective hole portions 120 is in the range of 88 degrees or more and 92 degrees or less with respect to the conveying direction T, and in this embodiment, it is orthogonal to the conveying direction T. In other words, in the hair implanting net 100, the straight line CL1 connecting the center positions C1 of the hole portions 120 is parallel to the axial direction L. As described above, in the subsequent hair implanting operation, the hair implanting operation is such that the hair material 101 already implanted in the hair implanting net 100 does not overlap the insertion planned position 122 and does not inhibit the hair implanting operation.

[0069] According to the hair implanting device 1 of this embodiment, in the hair implanting net 100, the hole portions 120 form a hole group arranged linearly in the width direction W, and the pulling means 12 is configured such that the angle of the straight line CL1 connecting the center positions C1 of the respective hole portions 120 of the hole group is in the range of 88 degrees or more and 92 degrees or less with respect to the conveying direction T of the hair implanting net 100, and at least pulls the hair implanting net 100 to the downstream side in the conveying direction T. That is, since the pulling means 12 pulls the hair implanting net 100 so as to be in a state where it is not substantially tilted, when continuously performing the hair implanting operation and the net hooking operation, the hair implanting net 100 does not bend, and it is easy to pass the hair implanting crochet portion 3 through the insertion planned position 122 of the hole portion 120, and the hair material 101 can be stably implanted into the hair implanting net 100 as compared with the conventional case.

[0070] According to the hair implanting device 1 of this embodiment, the pulling means 12 pulls the hair material 101 implanted on the hair implanting net 100 by the hair implanting net 100 and the hair implanting crochet portion 3 to the downstream side in the conveying direction T, so that the hair material 101 already implanted on the hair implanting net 100 does not flow to the upstream side in the conveying direction T, and it is less likely to interfere with the subsequent implantation of another hair material 101 on the hair implanting net 100.

[0071] According to the hair implanting device 1 of this embodiment, it has a sending-out means 15 that sends out the hair material 101 implanted by the hair implanting crochet portion 3 to the downstream side in the conveying direction T. Therefore, it is difficult for the hair material 101 already implanted on the hair implanting net 100 to overlap the insertion planned position 122, and it is less likely to interfere with the subsequent implantation of another hair material 101 on the hair implanting net 100.

[0072] According to the hair implanting device 1 of the present embodiment, since the feeding means 15 can feed out the hair material 101 implanted by the hair implanting crochet needle portion 3 downstream without contact, it is difficult for marks or the like to remain on the hair material 101 when feeding it out.

[0073] According to the hair implanting device 1 of the present embodiment, the pulling-in means 12 brings the first clamping roll 80 close to the second clamping roll 81 to clamp at least the hair implanting net 100, and by rotating the first clamping roll 80, the hair implanting net 100 is pulled in downstream in the conveying direction T. Therefore, the hair material 101 can be pulled in without being entangled with the pulling-in means 12.

[0074] According to the hair implanting device 1 of the present embodiment, in the axial direction L of the first clamping roll 80, the first rotating roll 90 contacts the first end side and the rotational force is transmitted, and the second rotating roll 91 contacts the second end side and the rotational force is transmitted. Therefore, in the axial direction L of the first clamping roll 80, the rotational force is easily dispersed, and it is difficult for a difference in rotational speed to occur between the first end side and the second end side.

[0075] According to the hair implanting device 1 of the present embodiment, the first rotating roll 90 and the second rotating roll 91 contact the first clamping roll 80 outside the hair implanting net 100 in the axial direction L of the first clamping roll 80. Therefore, it is difficult for the hair material 101 implanted in the hair implanting net 100 to be clamped between the rotating rolls 90, 91 and the first clamping roll 80.

[0076] According to the hair implanting device 1 of the present embodiment, the first clamping roll 80 has an adjustment axis L2 in a direction intersecting the axial direction L1 of the first clamping roll 80 and facing the second clamping roll 81, and the first clamping roll 80 is rotatable about the adjustment axis L2. Therefore, by aligning the axial direction L1 of the first clamping roll 80 with the axial direction L3 of the second clamping roll 81, the axial direction L1 of the first clamping roll 80 and the axial direction L3 of the second clamping roll 81 can be made parallel. By doing so, the hair material 101 can be clamped evenly.

[0077] According to the hair implanting device 1 of the present embodiment, the adjustment shaft L2 is located outside the hair implanting net 100 in the axial direction L1 of the first clamping roll 80. Therefore, by adjusting the angle on one side with reference to the adjustment shaft L2, the inclination of the first clamping roll 80 can be adjusted.

[0078] According to the hair implanting device 1 of the present embodiment, it has an eccentric portion 2 that supports the hair implanting net 100 in the main body portion 20. The eccentric portion 2 has the axis of the main body portion 20 eccentric with respect to the rotation axis. The hair implanting crochet portion 3 uses the rotation of the eccentric portion 2 to implant the hair material 101 onto the hair implanting net 100. Therefore, it is easy to automatically implant the hair material 101 onto the hair implanting net 100.

[0079] In the above-described embodiment, the pulling means 12 applies a rotational force to the first clamping roll 80 to rotate the first clamping roll 80 and pull in the hair implanting net 100. However, the present invention is not limited to this. The pulling means 12 may apply a rotational force to the second clamping roll 81 to rotate the second clamping roll 81 and pull in the hair implanting net 100.

[0080] In the above-described embodiment, the drive unit 82 evenly transmits a rotational force to the first clamping roll 80 in the width direction W by two rotating rolls 90, 91. However, the present invention is not limited to this. A rotational force may be evenly transmitted to the first clamping roll 80 in the width direction W by three or more rotating rolls, or if a rotational force can be evenly transmitted in the width direction W, a rotational force may be transmitted to the first clamping roll 80 by one rotating roll.

[0081] In the above-described embodiment, only the first clamping roll 80 is rotated among the first clamping roll 80 and the second clamping roll 81. However, the present invention is not limited to this. Both the first clamping roll 80 and the second clamping roll 81 may be rotated.

[0082] In the above-described embodiment, the pulling-in means 12 pulled in the hair material 101 implanted in the hair implanting net 100 downstream in the conveying direction T. However, the present invention is not limited to this. The pulling-in means 12 may pull in the hair material 101 implanted in the hair implanting net 100 upstream in the conveying direction T.

[0083] In the above-described embodiment, the sending-out means 15 sent out the hair material 101 implanted in the hair implanting net 100 downstream in the conveying direction T. However, the present invention is not limited to this. The sending-out means 15 may send out the hair material 101 implanted in the hair implanting net 100 upstream in the conveying direction T.

[0084] In the above-described embodiment, in the first hair material hooking operation, the hook portion 51 of the hair implanting crochet portion 3 was hooked on the proximal hair portion 110. However, the present invention is not limited to this. In the first hair material hooking operation, the hook portion 51 of the hair implanting crochet portion 3 may be hooked on the distal hair portion 111.

[0085] In the above-described embodiment, the first clamping roll 80 was a driven roll having the drive unit 82 as a power source. However, the present invention is not limited to this. The first clamping roll 80 may be a drive roll having a power source inside and capable of rotating itself.

[0086] In the above-described embodiment, the sending-out means 15 sent out the hair material 101 downstream in the conveying direction T by blowing air. However, the present invention is not limited to this. The sending-out means 15 may send out the hair material 101 downstream in the conveying direction T by other methods. For example, the hair material 101 may be sent out downstream in the conveying direction T using a comb.

[0087] In the above-described embodiment, the adjustment axis L2 was outside the hair implanting net 100 in the axial direction L1 of the first clamping roll 80. However, the present invention is not limited to this. It may be inside the hair implanting net 100.

[0088] In the above-described embodiment, the first clamping roll 80 was rotatable manually about the adjustment axis L2, but the present invention is not limited thereto. A drive source may be connected to the first clamping roll 80 so that it can be rotated automatically about the adjustment axis L2. In this case, the angle of the first clamping roll 80 was adjusted to be parallel to the second clamping roll 81 before the hair implanting operation, but the angle of the first clamping roll 80 may be adjusted to be parallel to the second clamping roll 81 during the hair implanting operation or for each hair implanting operation.

[0089] As long as the above-described embodiments are within the technical scope of the present invention, each component can be freely replaced or added between the embodiments.
