Description

Technical Field

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

[0002] Conventionally, a hair implanting device for connecting a hair material for hair implanting relative to a hair implanting net has been known (for example, Patent Document 1).

[0003] In the hair implanting device of Patent Document 1, a first crochet hook is hooked on the weft of a hair implanting net supported by an eccentric wheel, and the hooked portion is inserted between holes adjacent to each other across the weft of the hair implanting net to form a loop portion. Then, in the hair implanting device of Patent Document 1, after hooking the first crochet hook on the distal side line of the hair material with the first crochet hook as a reference, in a state where the hair material can freely move from a storage device, the hooked distal side line is pulled through the loop portion, whereby hair can be implanted relative to the hair implanting net.

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

[0005] However, in the hair implanting device of Patent Document 1, in order to continuously implant the hair material onto the hair implanting net, at the start of the first operation, it is necessary to overlap the insertion predetermined position of the first crochet hook with the holes of the hair implanting net.

[0006] In the hair implanting device of Patent Document 1, the deflection of the hair implanting net formed by a 1 / 4 rotation operation of the eccentric wheel in the fifth operation is absorbed by the rotation of the eccentric wheel in the seventeenth operation.

[0007] However, when the hair implanting net has elasticity, sometimes the deflection cannot be absorbed by the rotation of the eccentric wheel in the seventeenth operation, the hair implanting net is deformed due to the self-weight of the hair material, causing the hair implanting net to tilt, or the insertion predetermined position does not overlap with the holes of the hair implanting net. In this case, in the subsequent hair implanting operation, the first crochet hook contacts the weft of the hair implanting net, and it may be impossible to implant the hair material onto the hair implanting net. Summary of the Invention

[0008] Therefore, an object of the present invention is to provide a hair implanting device that can implant hair materials relative to a hair implanting net more stably than in the past.

[0009] One aspect of the present invention for solving the above problems is a hair implanting device, comprising: a net conveying unit that conveys a hair implanting net having a plurality of through-hole groups in which through-holes are arranged linearly in the width direction; a hair material supply unit that supplies a hair material toward the hair implanting net side from the middle part of the hair material; a hair implanting needle unit that implants a part of the middle part of the hair material supplied from the hair material supply unit with respect to the hair implanting net; and a pulling-in mechanism that pulls in at least the hair implanting net to the upstream side or the downstream side in the conveying direction so that the angle of the straight line connecting the central axes of the through-hole groups is in the range of 88 degrees or more and 92 degrees or less with respect to the conveying direction of the hair implanting net.

[0010] According to this aspect, by pulling in at least the hair implanting net by the pulling-in mechanism so that the hair implanting net is in a substantially non-inclined state, the hair implanting net does not flex and it is easy to continuously pass the hair implanting needle unit through the holes, and it is possible to stably implant the hair material on the hair implanting net as compared with the prior art.

[0011] However, in the hair implanting device of Patent Document 1, after implanting the hair material on the hair implanting net, the hair material is made to fall downward by a thread removing rod to arrange the hair, but the arranged hair material is in a freely movable state. Since the arranged hair material, for example, due to static electricity or the like, follows the rising of the thread removing rod, and important factors such as a part of the hair material following the thread removing rod, sometimes the hair material overlaps with the upstream hair implanting part. When the hair material overlaps with the hair implanting part, sometimes the hair material hinders the movement of the hair implanting crochet needle and it becomes impossible to continue implanting the hair.

[0012] Therefore, a preferred aspect is that the pulling-in mechanism pulls in the hair implanting net and the hair material implanted by the hair implanting needle unit to the downstream side in the conveying direction.

[0013] According to this aspect, the hair material implanted on the hair implanting net does not flow to the upstream side in the conveying direction, and it is difficult to become an obstacle when continuously implanting the hair material on the hair implanting net.

[0014] A preferred aspect is that there is a sending-out mechanism that sends out the hair material implanted by the hair implanting needle unit to the downstream side in the conveying direction.

[0015] A preferred aspect is that the sending-out mechanism can send out the hair material implanted by the hair implanting needle unit to the downstream side without contact.

[0016] Preferably, the pulling-in mechanism has a first clamping roller, a second clamping roller, and a moving mechanism for relatively moving the first clamping roller relative to the second clamping roller. The pulling-in mechanism clamps at least the hair implanting net by approaching the first clamping roller to the second clamping roller, and rotates the first clamping roller and / or the second clamping roller, thereby pulling the hair implanting net to the upstream side or the downstream side in the conveying direction.

[0017] Preferably, there are a first rotating roller and a second rotating roller. The first clamping roller is rotated by being transmitted with the respective rotational forces of the first rotating roller and the second rotating roller. The first clamping roller contacts the first rotating roller at a first end side in the axial direction of the first clamping roller to transmit the rotational force, and contacts the second rotating roller at a second end side to transmit the rotational force.

[0018] Preferably, there are a first rotating roller and a second rotating roller. The first clamping roller is rotated by being transmitted with the respective rotational forces of the first rotating roller and the second rotating roller. The first rotating roller and the second rotating roller are in contact with the first clamping roller outside the hair implanting net in the axial direction of the first clamping roller.

[0019] Preferably, the first clamping roller has an adjustment shaft in a direction crossing the axial direction of the first clamping roller and facing the second clamping roller. The first clamping roller can rotate in the circumferential direction with the adjustment shaft as the center.

[0020] Preferably, the adjustment shaft is outside the hair implanting net in the axial direction of the first clamping roller.

[0021] Preferably, there is a support roller that supports the hair implanting net through a main body portion. The support roller is such that the axis of the main body portion is eccentric with respect to the rotation axis, and the hair implanting needle portion implants the hair material relative to the hair implanting net by the rotation of the support roller.

[0022] As long as the above-described embodiments are included within the technical scope of the present invention, they can be subordinate to each other, cite a part of the configuration, or replace a part of the configuration among the respective embodiments.

[0051] Hereinafter, the implementation manners of the present invention will be described in detail.

[0052] The hair implanting device 1 of the first implementation manner of the present invention is an automatic hair implanting device that automatically implants the hair material 101 into the hair implanting net 100. As Figure 1 shown, it includes an eccentric wheel part (hereinafter, also simply referred to as the eccentric part 2) (supporting roller), a hair implanting hook needle part 3 (hair implanting needle part), a pulling-out hook needle part 5, a hair material supply part 6, a guide roller 7, a hair material pull-in part 8, a hair material falling part 10, a conveying roller 11 (net conveying part), a pull-in mechanism 12, and a feed-out mechanism 15.

[0053] (Eccentric part 2)

[0054] As Figure 2 shown, the eccentric part 2 is a long strip extending along the width direction W (axial direction L), and includes a main body part 20 and rotating shaft parts 21a, 21b.

[0055] The eccentric part 2 is a rotational force conversion component that converts rotational motion into simple harmonic vibration with the rotating shaft parts 21a, 21b offset from the central axis of the main body part 20, and is a supporting roller for supporting the hair implanting net 100.

[0056] The main body part 20 is a cylindrical part extending along the axial direction L, and includes a concave part 28 with a part of the outer circumference recessed.

[0057] The concave part 28 is a notch groove into which a part of the hair implanting hook needle part 3 can be inserted, and is a groove formed throughout the entire extension direction (axial direction L) of the main body part 20.

[0058] The rotating shaft portions 21a and 21b are shaft portions that serve as the rotation center of the eccentric portion 2.

[0059] The rotating shaft portions 21a and 21b extend outward from both end portions of the main body portion 20 in the axial direction L, and the central axis is set at a position offset from the central axis of the main body portion 20.

[0060] The eccentric portion 2 can change its posture between a first posture and a second posture by rotating around the rotating shaft portions 21a and 21b.

[0061] As Figure 5 shown in (a) of , the first posture is a facing posture in which the concave portion 28 of the main body portion 20 is located on the side of the hair implanting crochet hook portion 3 and faces the hair implanting crochet hook portion 3.

[0062] As Figure 5 shown in (b) of , the second posture is a vertical posture in which the concave portion 28 of the main body portion 20 is located on the side of the hair material supply portion 6 and faces upward.

[0063] (Hair implanting crochet hook portion 3)

[0064] The hair implanting crochet hook portion 3 is a hair implanting needle portion that implants the hair material 101 onto the hair implanting net 100, and is a rod-shaped body with a hook-shaped claw at the front end.

[0065] As Figure 1 shown, the hair implanting crochet hook portion 3 is a latch crochet hook having a needle shaft portion 50, a hook portion 51, and a latch portion 52.

[0066] (Pull-out crochet hook portion 5)

[0067] The pull-out crochet hook portion 5 is a crochet hook that pulls out the hair material 101 from the hair material supply portion 6.

[0068] The pull-out crochet hook portion 5 is a rod-shaped body with a hook-shaped claw at the front end, and as Figure 1 shown, it has a needle shaft portion 60 and a hook portion 61.

[0069] (Hair material supply portion 6)

[0070] The hair material supply portion 6 is a hair material storage portion that stores the hair material 101 to be implanted onto the hair implanting net 100, and as Figure 1 shown, an extraction hole 55 for extracting and supplying the stored hair material 101 is provided at the bottom.

[0071] (Guide roller 7)

[0072] As Figure 1As shown in (b) of , the guide roller 7 is a roller having a groove portion 70 in a part of its outer peripheral surface, and a part of the hair material 101 pulled out from the hair material supply portion 6 by the pulling crochet portion 5 passes through the groove portion 70, thereby adjusting the position in the axial direction L to converge within a specified range.

[0073] (Hair material pulling-in portion 8)

[0074] The hair material pulling-in portion 8 is a pulling rod that pulls the hair material 101 pulled out from the hair material supply portion 6 by the pulling crochet portion 5 to the upstream side in the conveying direction T with respect to the hair implanting position of the hair implanting net 100.

[0075] (Hair material falling portion 10)

[0076] The hair material falling portion 10 is a falling rod that causes the hair material 101 pulled out from the hair material supply portion 6 by the pulling crochet portion 5 to fall downward with respect to the hair implanting position of the hair implanting net 100.

[0077] (Conveying roller 11)

[0078] The conveying roller 11 is a supporting roller that supports the hair implanting net 100 in such a manner that the hair implanting net 100 passes through the eccentric portion 2, and is a net conveying portion that conveys the hair implanting net 100 along the conveying direction T by rotation.

[0079] (Pulling-in mechanism 12)

[0080] The pulling-in mechanism 12 is a portion that pulls at least the hair implanting net 100 to the downstream side in the conveying direction T so that Figure 3 the center position C1 of a specific hole portion 120 of the hair implanting net 100 shown in is aligned with the position (insertion predetermined position 122) of the projection plane in the front-rear direction X of the hair implanting crochet portion 3.

[0081] As Figure 2 shown in , the pulling-in mechanism 12 includes a first clamping roller 80, a second clamping roller 81, and a drive unit 82.

[0082] The first clamping roller 80 is a driven roller whose rotation axis extends along 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.

[0083] The first clamping roller 80 can move relative to the second clamping roller 81 in a relatively approaching and separating manner by a moving mechanism (not shown), and can move between Figure 2 the clamping position shown by the solid line in where it can at least clamp the hair implanting net 100 with the second clamping roller 81, and Figure 2 the non-contact position shown by the virtual line in where it separates from the hair implanting net 100 and does not contact the hair implanting net 100.

[0084] AsFigure 4 As shown, the first clamping roller 80 has an adjustment axis L2 in the crossing direction that crosses the axial direction L1 of the first clamping roller 80 and is in the direction toward the second clamping roller 81, and can rotate about the adjustment axis L2. That is, the first clamping roller 80 can move with a vertical direction component about the adjustment axis L2.

[0085] The first clamping roller 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 portion.

[0086] The position of the adjustment axis L2 of the first clamping roller 80 is preferably outside the axial direction L of the hair implanting net 100 and in a position where it does not contact the hair implanting net 100 during the hair implanting operation.

[0087] The material of the first clamping roller 80 is not particularly limited, and polyurethane resin, ethylene propylene rubber, etc. can be used.

[0088] The first clamping roller 80 preferably has a hardness of 20 or more and 30 or less as measured by a type A durometer conforming to JIS K 6253-3:2012 (ISO 7619-1). Thereby, even if the thickness increases as the hair material 101 is implanted into the hair implanting net 100, it is possible to suppress the hair implanting net 100 from being pulled due to the rotation of the first clamping roller 80.

[0089] The second clamping roller 81 is a roller that is paired with the first clamping roller 80 and sandwiches the hair implanting net 100 and the hair material 101 together with the first clamping roller 80.

[0090] The second clamping roller 81 may be a driving roller having a power source and capable of rotating by the power source, or may be an idle roller without a power source.

[0091] The drive unit 82 transmits a rotational force to the first clamping roller 80 to rotate the first clamping roller 80.

[0092] As Figure 2 shown, the drive unit 82 is composed of a plurality of rotating rollers 90, 91.

[0093] Each of the rotating rollers 90, 91 is a driving roller having a power source such as a servo motor and capable of rotating by the power source.

[0094] That is, the drive unit 82 can directly or via other components transmit the rotational force of the rotating rollers 90, 91 to the first clamping roller 80 to rotate the first clamping roller 80.

[0095] (Delivery mechanism 15)

[0096] The delivery mechanism 15 is a part that delivers the hair material 101 implanted on the hair implanting net 100 downstream along the conveying direction T, and is also an arranging mechanism for arranging the hair material 101 implanted on the hair implanting net 100.

[0097] The delivery mechanism 15 in the present embodiment non - contactingly delivers the hair material 101 implanted on the hair implanting net 100 to the downstream side in the conveying direction T.

[0098] Specifically, as Figure 1 shown, the delivery mechanism 15 is a blowing mechanism as follows: It has a blow - out port 95, blows air from the blow - out port 95 to the hair material 101 implanted on the hair implanting net 100, and delivers the hair material 101 implanted on the hair implanting net 100 to the downstream side in the conveying direction T.

[0099] The delivery mechanism 15 can also blow air containing ions for removing static electricity. Thereby, the static electricity charged on the surface of the hair material 101 can be neutralized by the ions and become electrically neutral.

[0100] (Hair implanting net 100)

[0101] As Figure 3 shown, the hair implanting net 100 is a stretchable net formed by a plurality of wire meshes 121 into a mesh shape, and has a plurality of hole portions 120 (through - holes, through - hole groups).

[0102] The hair implanting net 100 in the present embodiment has a honeycomb structure and can stretch in the conveying direction T and the width direction W.

[0103] The hole portion 120 is a hole having a hexagonal shape in a top view, and each side is formed by the wire mesh 121.

[0104] The hole portion 120 is a through - hole penetrating along the thickness direction, and constitutes a group of through - holes arranged in a row in the width direction W, and the group of through - holes is arranged in parallel in the conveying direction T.

[0105] (Hair material 101)

[0106] The hair material 101 is a linear body implanted on the hair implanting net 100.

[0107] The hair material 101 can use artificial hair, human hair, animal hair, etc. composed of resin fibers, etc.

[0108] In the present embodiment, the hair material 101 is bundled in multiple strands and used as a hair bundle.

[0109] Next, the positional relationship of each part of the hair implanting device 1 in the present embodiment will be described. In addition, regarding the eccentric part 2, Figure 1The concave portion 28 of the main body portion 20 shown is located on the side of the hair implanting crochet portion 3, and the description will be made based on the first posture facing the hair implanting crochet portion 3 side.

[0110] As Figure 1 shown, the hair implanting device 1 has a hair implanting net 100 suspended on the eccentric portion 2, the conveying roller 11, and the second clamping roller 81.

[0111] The eccentric portion 2 has a rotary shaft portion 21a, 21b that is shaft-supported and can rotate circumferentially about the rotary shaft portion 21a, 21b.

[0112] As Figure 1 shown, the hair implanting crochet portion 3 assumes a horizontal posture extending in the horizontal direction, and the hook portion 51 faces the concave portion 28 of the main body portion 20 in the front-rear direction X.

[0113] The pulling-out crochet portion 5 has a hook portion 61 at the front end located on the upper side and assumes a vertical posture extending in the vertical direction, and faces the take-out hole 55 of the hair material supply portion 6 in the height direction Y (vertical direction).

[0114] The hair material pulling-in portion 8 is located on the lower side than the hair material supply portion 6 in the height direction Y, and is located on the upper side than the eccentric portion 2.

[0115] As Figure 1 shown, the pulling-in mechanism 12 is in a position facing the first clamping roller 80 and the second clamping roller 81 with the hair implanting net 100 interposed therebetween.

[0116] As Figure 3 shown in (b) of [], the rotating rollers 90, 91 of the drive unit 82 pass through the center of the width direction W of the hair implanting net 100 and are symmetric (mirror image) with respect to the plane orthogonal to the width direction W (axial direction L) of the first clamping roller 80.

[0117] As Figure 3 shown in (b) of [], the rotating rollers 90, 91 are such that in the width direction W, they contact at positions outside the hair implanting net 100 and at positions that are approximately equidistant from the center position C2 (the center position of the width direction W of the hair implanting net 100) of the first clamping roller 80. That is, the difference between the distance D1 between the first rotating roller 90 and the center position C2 in the width direction W and the distance D2 between the second rotating roller 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 the present embodiment, the distance D2 between the second rotating roller 91 and the center position C2 in the width direction W is equal.

[0118] The drive unit 82 is configured such that a part of the outer circumferential surface of each of the rotating rollers 90 and 91 contacts the outer circumferential surface of the first clamping roller 80, and the rotational force of the rotating rollers 90 and 91 is transmitted to the first clamping roller 80 via the contact portion, enabling the first clamping roller 80 to rotate in a driven manner.

[0119] The feeding mechanism 15 is configured such that the blowing outlet 95 is located more downstream in the conveying direction T than the insertion predetermined position 122 of the hair implanting net 100 and faces the hair implanting net 100 side.

[0120] Next, the hair implanting operation of the hair implanting device 1 of the present embodiment will be described.

[0121] First, as a preliminary preparation for the hair implanting operation of the hair implanting device 1, the first clamping roller 80 is rotated to be aligned parallel to the axial direction L3 of the second clamping roller 81, and it is adjusted so that the first clamping roller 80 and the second clamping roller 81 clamp the hair implanting net 100 in a linear shape, and then the hair implanting operation of the hair implanting device 1 is performed.

[0122] The hair implanting operation of the hair implanting device 1 is as follows. Figure 5 As shown in (a) of [], the pulling-out crochet portion 5 is raised to hook the hair material 101 in the hair material supply portion 6, then it is lowered to the original reference position to pull out the middle portion of the hair material 101 in the hair material supply portion 6 downward from the extraction hole 55, and the pulling-out crochet portion 5 is displaced from the reference position in the axial direction L of the eccentric portion 2 (hair material pulling-out operation).

[0123] At this time, as shown in (a) of [], the hair material 101 in the hair material supply portion 6 is pulled out into a "V" shape by the hook portion 61 of the pulling-out crochet portion 5, and the engaging portion (hooking portion) that engages with the hook portion 61 of the pulling-out crochet portion 5 becomes a position lower than the apex of the eccentric portion 2. In addition, the hair material 101 is divided into a proximal-side hair portion 110 and a distal-side hair portion 111 with the engaging portion (folding-back portion) that engages with the hook portion 61 of the pulling-out crochet portion 5 as a reference. Figure 5

[0124] Figure 5 In addition, in an operation different from the hair material pulling-out operation, as shown by the arrow in (a) of [], the hair implanting crochet portion 3 is advanced toward the eccentric portion 2, and the hook portion 51 of the hair implanting crochet portion 3 is disposed in the concave portion 28 of the eccentric portion 2 through the hole portion 120a of the hair implanting net 100 on the eccentric portion 2. Then, as shown in (b) of [], the hair implanting crochet portion 3 is retracted and raised from the concave portion 28 of the eccentric portion 2 (net hooking operation). Figure 5

[0125] ​​​At this time, the hair-implanting crochet needle portion 3 is lifted upward by retreating and rising, and the hook portion 51 hooks the weft wire, i.e., the net wire 121, at the edge of the forming hole portion 120a of the hair-implanting net 100 on the eccentric portion 2. That is, the hair-implanting crochet needle portion 3 hooks the hook portion 51 on the net wire 121 extending along the crossing direction (orthogonal direction in this embodiment) with respect to the conveying direction T.

[0126] Next, in a state where the hair-implanting crochet needle portion 3 is hooked on the net wire 121, as shown by the arrow in (b) of Figure 5 , the first clamping roller 80 is moved away from the hair-implanting net 100, and the eccentric portion 2 is rotated 90 degrees in the forward direction R1 to become a second posture, and the hook portion 51 of the hair-implanting crochet needle portion 3 is extended from the concave portion 28 (eccentric wheel rotation operation).

[0127] At this time, with the rotation of the eccentric portion 2, the hair-implanting crochet needle portion 3 is inserted across the hair-implanting net 100 through the hole portions 120a and 120b adjacent to each other across the net wire 121.

[0128] In addition, as shown in (b) of Figure 5 , the first clamping roller 80 is moved to a non-contact position far enough away from the hair-implanting net 100 so as not to contact the hair-implanting net 100 in a state where the eccentric portion 2 is rotated to the second posture.

[0129] Next, as shown in (a) of Figure 6 , the hair-implanting crochet needle portion 3 is further advanced and the hair-implanting crochet needle portion 3 is rotated 90 degrees in the circumferential direction, and the pulling-out crochet needle portion 5 is moved so that the hook portion 51 of the hair-implanting crochet needle portion 3 hooks the proximal hair portion 110 (first hair material hooking operation).

[0130] At this time, with the advancement of the hair-implanting crochet needle portion 3, a part of the needle shaft portion 50 is inserted across the hair-implanting net 100 through the hole portions 120a and 120b adjacent to each other across the net wire 121.

[0131] Next, as shown by the arrow in (a) of Figure 6 , the hair-implanting crochet needle portion 3 hooked on the proximal hair portion 110 is retreated and the pulling-out crochet needle portion 5 is returned to the original reference position, and the hair-implanting crochet needle portion 3 is further rotated 90 degrees in the circumferential direction to a posture where the hook portion 51 faces upward, and is pulled out from the hair-implanting net 100 to form a loop portion 112 through the proximal hair portion 110 (loop portion forming operation).

[0132] At this time, the latch portion 52 of the hair implanting crochet portion 3 is closed by the wire 121 of the hair implanting net 100, and the hair implanting crochet portion 3 is pulled out from the hair implanting net 100 while holding the proximal hair portion 110 of the hair material 101. In addition, the middle portion of the hair material 101 forms a loop portion 112 through the hole portions 120a and 120b of the hair implanting net 100, and the loop portion 112 is exposed from the hole portion 120a of the hair implanting net 100 toward the hair implanting crochet portion 3 side.

[0133] Next, as shown in Figure 6 (b) thereof, the hair implanting crochet portion 3 is rotated 360 degrees to twist the loop portion 112 of the hair material 101, and as shown by the arrow in Figure 6 (b) thereof, the hair implanting crochet portion 3 is raised and displaced in the axial direction L of the eccentric portion 2 (hair material twisting operation).

[0134] Next, as shown in Figure 7 (a) thereof, the hair implanting crochet portion 3 advances beyond the proximal hair portion 110, the hair implanting crochet portion 3 is slightly retracted and rotated 90 degrees in the circumferential direction, the hair implanting crochet portion 3 is displaced in the axial direction L of the eccentric portion 2 and returns to a position overlapping the hair material 101, and the front end of the hair implanting crochet portion 3 is hooked on the proximal hair portion 110 of the hair material 101 (second hair material hooking operation).

[0135] Next, as shown in Figure 7 (b) thereof, the hair implanting crochet portion 3 is further retracted and rotated 90 degrees to assume a posture in which the hook portion 51 faces upward, and the engaging portion of the hair material 101 with the hair implanting crochet portion 3 passes through the loop portion 112 (loop portion passing operation)

[0136] At this time, the latch portion 52 of the hair implanting crochet portion 3 is closed by the loop portion 112 of the hair implanting net 100.

[0137] Next, the pull-out crochet portion 5 is raised and assumes a position deviated from the position of the hair material 101, thereby releasing the engagement between the pull-out crochet portion 5 and the hair material 101. As shown in Figure 8 (a) thereof, while rotating the hair implanting crochet portion 3 720 degrees, it is further retracted to allow the distal hair portion 111 to pass through the loop portion 112, and the pull-out crochet portion 5 is lowered (hair material twisting operation).

[0138] Next, as shown in Figure 8 (b) thereof, the distal hair portion 111 is pulled in by the hair material pulling-in portion 8 and flows to the downstream side 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 as the posture is changed, the distal hair portion 111 located upstream of the loop portion 112 in the conveying direction T is dropped through the hair material dropping portion 10 (dropping operation).

[0139] Next, as shown by the arrow in (a) of Figure 9 the hair material 101 planted on the hair planting net 100 is sent out non - contactly to the downstream side in the conveying direction T by the sending mechanism 15 and arranged (arrangement process).

[0140] Specifically, by the sending mechanism 15, air is blown so that the front - end side of the proximal - side hair portion 110 and the front - end side of the distal - side hair portion 111 are located on the downstream side in the conveying direction T for arrangement.

[0141] Next, as shown in (b) of Figure 9 the first clamping roller 80 of the pulling - in mechanism 12 is moved toward the second clamping roller 81, and the proximal - side hair portion 110 and the distal - side hair portion 111 arranged through the arrangement process together with the hair planting net 100 are clamped by the first clamping roller 80 and the second clamping roller 81, and the respective rotating rollers 90, 91 of the driving unit 82 are rotated to rotate the first clamping roller 80, and the hair planting net 100, the proximal - side hair portion 110, and the distal - side hair portion 111 are pulled in the downstream direction (pulling - in process).

[0142] At this time, the hair planting net 100 is pulled in together with the first clamping roller 80, the second clamping roller 81, the proximal - side hair portion 110, and the distal - side hair portion 111 to apply tension.

[0143] Here, as shown in (b) of Figure 3 the distance D1 between the first rotating roller 90 and the center position C2 in the width direction W and the distance D2 between the second rotating roller 91 and the center position C2 in the width direction W are equal, and due to the same output rotation, a rotational force is equally applied to the hair planting net 100. As shown in (a) of Figure 3 the center positions C1 of the hole portions 120 are arranged linearly in the width direction W, and the insertion predetermined positions 122 opposed to the hair planting crochet portions 3 are substantially aligned in the width direction W.

[0144] That is, for the hair planting 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 is orthogonal to the conveying direction T in the present embodiment. In other words, for the hair planting net 100, the straight line CL1 connecting the center positions C1 of the hole portions 120 is parallel to the axial direction L.

[0145] As described above, in the subsequent hair - planting operation, the hair material 101 planted on the hair planting net 100 does not overlap with the insertion predetermined position 122 and does not interfere with the hair - planting operation.

[0146] In the hair implanting device 1 according to the present embodiment, the hair implanting net 100 has hole portions 120 formed in a linear array in the width direction W. The pulling-in mechanism 12 pulls in the hair implanting net 100 at least toward the downstream side in the conveying direction T so 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. That is, the pulling-in mechanism 12 pulls in the hair implanting net 100 in a substantially non-inclined state. Therefore, when the hair implanting operation is then performed and the net hooking operation is carried out, the hair implanting net 100 does not flex, and it is easy for the hair implanting hook needle portion 3 to pass through the insertion predetermined position 122 of the hole portion 120. Compared with the prior art, the hair material 101 can be stably implanted into the hair implanting net 100.

[0147] In the hair implanting device 1 according to the present embodiment, the pulling-in mechanism 12 pulls in the hair implanting net 100 and the hair material 101 implanted into the hair implanting net 100 by the hair implanting hook needle portion 3 toward the downstream side in the conveying direction T. Therefore, the hair material 101 implanted into the hair implanting net 100 does not flow toward the upstream side in the conveying direction T and is less likely to become an obstacle when other hair materials 101 are then implanted into the hair implanting net 100.

[0148] The hair implanting device 1 according to the present embodiment includes a feeding-out mechanism 15 that feeds out the hair material 101 implanted by the hair implanting hook needle portion 3 toward the downstream side in the conveying direction T. Therefore, the hair material 101 implanted into the hair implanting net 100 is less likely to overlap with the insertion predetermined position 122 and is less likely to become an obstacle when other hair materials 101 are then implanted into the hair implanting net 100.

[0149] In the hair implanting device 1 according to the present embodiment, the feeding-out mechanism 15 can feed out the hair material 101 implanted by the hair implanting hook needle portion 3 in a non-contact manner toward the downstream side. Therefore, no traces or the like remain on the hair material 101 during feeding out.

[0150] In the hair implanting device 1 according to the present embodiment, the pulling-in mechanism 12 brings the first clamping roller 80 close to the second clamping roller 81 to at least clamp the hair implanting net 100 and rotates the first clamping roller 80, thereby pulling in the hair implanting net 100 toward the downstream side in the conveying direction T. Therefore, the hair material 101 can be pulled in without being wound around the pulling-in mechanism 12.

[0151] In the hair implanting device 1 according to the present embodiment, on the axial direction L of the first clamping roller 80, the first rotating roller 90 contacts the first end side to transmit the rotational force, and the second rotating roller 91 contacts the second end side to transmit the rotational force. Therefore, on the axial direction L of the first clamping roller 80, the rotational force is easily dispersed, and it is difficult to generate a difference in rotational speed between the first end side and the second end side.

[0152] In the hair implanting device 1 according to the present embodiment, the first rotating roller 90 and the second rotating roller 91 are in contact with the first clamping roller 80 on the outside of the hair implanting net 100 in the axial direction L of the first clamping roller 80. Therefore, the hair material 101 implanted on the hair implanting net 100 is difficult to be clamped between the rotating rollers 90 and 91 and the first clamping roller 80.

[0153] In the hair implanting device 1 according to the present embodiment, the first clamping roller 80 has an adjustment axis L2 in the crossing direction crossing the axial direction L1 of the first clamping roller 80 and in the direction toward the second clamping roller 81, and the first clamping roller 80 can rotate about the adjustment axis L2. Therefore, by making the angle of the axial direction L1 of the first clamping roller 80 coincide with the axial direction L3 of the second clamping roller 81, the axial direction L1 of the first clamping roller 80 can be made parallel to the axial direction L3 of the second clamping roller 81. Thereby, the hair material 101 can be clamped evenly.

[0154] In the hair implanting device 1 according to the present embodiment, the adjustment axis L2 is on the outside of the hair implanting net 100 in the axial direction L1 of the first clamping roller 80. Therefore, by adjusting the angle of one side based on the adjustment axis L2, the inclination angle of the first clamping roller 80 can be adjusted.

[0155] In the hair implanting device 1 according to the present embodiment, there is an eccentric portion 2 that supports the hair implanting net 100 by the main body portion 20. The axis of the main body portion 20 of the eccentric portion 2 is eccentric with respect to the rotation axis, and the hair implanting hook needle portion 3 implants the hair material 101 with respect to the hair implanting net 100 by the rotation of the eccentric portion 2. Therefore, it is easy to automatically implant the hair material 101 with respect to the hair implanting net 100.

[0156] In the above embodiment, the pulling-in mechanism 12 applies a rotational force to the first clamping roller 80 to rotate the first clamping roller 80 to pull in the hair implanting net 100, but the present invention is not limited thereto. The pulling-in mechanism 12 may also apply a rotational force to the second clamping roller 81 to rotate the second clamping roller 81 to pull in the hair implanting net 100.

[0157] In the above embodiment, the drive unit 82 evenly transmits the rotational force to the first clamping roller 80 in the width direction W through the two rotating rollers 90 and 91, but the present invention is not limited thereto. The rotational force may also be evenly transmitted to the first clamping roller 80 in the width direction W through three or more rotating rollers, and as long as the rotational force can be evenly transmitted in the width direction W, the rotational force may also be transmitted to the first clamping roller 80 through one rotating roller.

[0158] In the above embodiment, only the first clamping roller 80 among the first clamping roller 80 and the second clamping roller 81 rotates, but the present invention is not limited thereto. Both the first clamping roller 80 and the second clamping roller 81 may rotate.

[0159] In the above-described embodiment, the pulling-in mechanism 12 pulls the hair material 101 implanted in the hair implanting net 100 downstream in the conveying direction T, but the present invention is not limited thereto. The pulling-in mechanism 12 may also pull the hair material 101 implanted in the hair implanting net 100 upstream in the conveying direction T.

[0160] In the above-described embodiment, the feeding-out mechanism 15 feeds out the hair material 101 implanted in the hair implanting net 100 downstream in the conveying direction T, but the present invention is not limited thereto. The feeding-out mechanism 15 may also feed out the hair material 101 implanted in the hair implanting net 100 upstream in the conveying direction T.

[0161] In the above-described embodiment, in the first hair material hooking operation, the hook portion 51 of the hair implanting hook needle portion 3 is hooked on the proximal-side hair portion 110, but the present invention is not limited thereto. In the first hair material hooking operation, the hook portion 51 of the hair implanting hook needle portion 3 may also be hooked on the distal-side hair portion 111.

[0162] In the above-described embodiment, the first clamping roller 80 is a driven roller with the driving unit 82 as the power source, but the present invention is not limited thereto. The first clamping roller 80 may also be a driving roller having a power source inside and capable of self-rotation.

[0163] In the above-described embodiment, the feeding-out mechanism 15 feeds out the hair material 101 downstream in the conveying direction T by blowing air, but the present invention is not limited thereto. The feeding-out mechanism 15 may also feed out the hair material 101 downstream in the conveying direction T by other methods. For example, a comb may also be used to feed out the hair material 101 downstream in the conveying direction T.

[0164] In the above-described embodiment, the adjustment shaft L2 is outside the hair implanting net 100 in the axial direction L1 of the first clamping roller 80, but the present invention is not limited thereto. It may also be inside the hair implanting net 100.

[0165] In the above-described embodiment, the first clamping roller 80 can be rotated manually around the adjustment shaft L2, but the present invention is not limited thereto. A drive source may also be connected to the first clamping roller 80 to rotate it automatically around the adjustment shaft L2.

[0166] In this case, the angle of the first clamping roller 80 is adjusted to be parallel to the second clamping roller 81 before the hair implanting operation, but the angle of the first clamping roller 80 may also be adjusted to be parallel to the second clamping roller 81 during the hair implanting operation or for each hair implanting operation.

[0167] As long as the above-described embodiments are included in the technical scope of the present invention, the respective components can be freely replaced and added among the embodiments.
