Description

[Technical field]

[0001] The present invention relates to an automatic hair implantation device and a hair material bundle for the automatic hair implantation device. [Background technology]

[0002] An automatic hair implantation device that ties a hair material to a hair implantation net and implants the hair is known. Such an automatic hair implantation device is disclosed in, for example, Patent Document 1.

[0003] The automatic hair implantation device of Patent Document 1 includes a stocker that stores multiple hair materials, an eccentric on which a hair implantation net is deployed, a first hook, and a second hook. The second hook pulls out the hair material from the outlet of the stocker. The first hook captures the pulled out hair material and connects it to the hair implantation net deployed on the eccentric for implantation. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6533350 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the automatic hair implantation device of Patent Document 1, friction caused by the hair material pulled out from the outlet by the second hook may cause a part of the hair material in the stocker other than the hair material in question to protrude from the outlet to the outside. The hair material protruding from the outlet may not be captured by the second hook and remain in the stocker, or the hair material may fall off the outlet and interfere with the second hook or the equipment in the automatic hair implantation device, causing poor hair implantation.

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide an automatic hair implantation device and a hair material bundle for an automatic hair implantation device that can prevent part of the hair material in the stocker from protruding to the outside through the removal outlet. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the automatic hair implantation device disclosed below comprises a stocker having an outlet and in which a plurality of hair materials are arranged across the outlet, from which some of the plurality of hair materials are removed by a pulling hook, and a pressing unit that presses at least some of the plurality of hair materials in a direction perpendicular to the longitudinal direction of the plurality of hair materials, and presses at least some of the plurality of hair materials other than the hair material pulled out from the stocker.

[0008] In addition, a hair material bundle for an automatic hair implantation device comprises a stocker having an outlet and in which multiple hair materials are arranged across the outlet, and some of the multiple hair materials are removed from the outlet by a withdrawal hook, the hair material bundle for an automatic hair implantation device comprising the multiple hair materials arranged in the stocker, and an elastic member that binds the multiple hair materials together. Effect of the Invention

[0009] According to the above configuration, the pressing portion or elastic member presses at least a portion of the hair material other than the hair material being pulled out of the storage container, thereby preventing the other hair materials from protruding from the outlet due to being dragged by friction with the hair material being pulled out of the storage container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] An embodiment of the present invention will be described below with reference to the drawings. The present invention is not limited to the following embodiment, and appropriate design changes can be made within the scope of the configuration of the present invention. In the following description, the same parts or parts having similar functions are commonly designated by the same reference numerals in different drawings, and repeated description thereof will be omitted. The configurations described in the embodiment and the modified examples may be appropriately combined or modified. In order to make the description easier to understand, the configurations are shown simplified or schematic, and some components are omitted in the drawings referred to below.

[0012] <<Examples of the configuration and operation of an automatic hair transplant device>> First, the basic configuration and operation of the automatic hair implantation device according to the embodiment of the present invention will be described with reference to the drawings. Note that, here, only one example of the basic configuration and operation of the automatic hair implantation device will be described as a premise for explaining the main parts of the present invention. It is of course possible to adopt a configuration and operation different from the configuration and operation of the automatic hair implantation device described here as long as there is no contradiction with the configuration and operation of the main parts of the present invention.

[0013] Fig. 1 is a side view showing the structure and initial position of the automatic hair implantation device. Fig. 2 is a front view of the automatic hair implantation device in the state of Fig. 1, seen from the rear toward the front. As shown in Fig. 1, the automatic hair implantation device 120 includes an eccentric 10, a hair implantation hook 20, an extraction hook 30, a stocker 40, a thread positioning bar 50, a thread drop bar 60, a thread retraction bar 70, a reversing roller 80, a magnet 90 shown in Fig. 11, a drive mechanism not shown, a control device, etc., and the eccentric 10, the hair implantation hook 20, the extraction hook 30, the thread drop bar 60, and the thread retraction bar 70 each perform the first to eighteenth operations shown in Figs. 2 to 11 according to the control of the drive mechanism by the control device, and the hair material 100a is captured one by one from the stocker 40 and tied to the weft thread 202 of the hair implantation net 200 for implantation. In the side views and front views shown in Figs. 1 to 21, the left-right direction in the drawings is the horizontal direction, and the up-down direction is the vertical direction.

[0014] The hair material 100a includes artificial hair (fiber, synthetic fiber), human hair (hair taken from humans), animal hair (hair taken from animals other than humans), or a mixture of these, and includes all hair or hair-like materials that can be implanted by the automatic hair implantation device 120. The hair implantation net 200 is formed in a mesh shape consisting of multiple warp threads 201 and multiple weft threads 202, and each of the warp threads 201 and the weft threads 202 may be a single thread made by twisting multiple raw threads together, or may be a single raw thread.

[0015] First, the configuration of the automatic hair implantation device 120 and the initial position when the automatic hair implantation device 120 operates will be described. As shown in FIG. 1, a hair material bundle 100b consisting of a plurality of hair materials 100a cut in advance is placed in a stocker 40 arranged above the eccentric 10. A pull-out hook 30 is arranged below an outlet 42 in the stocker 40, and the eccentric 10 is arranged between the hair implantation hook 20 and the pull-out hook 30. Hereinafter, the direction in the horizontal plane in which the pull-out hook 30 is located as viewed from the eccentric 10 is referred to as the rear, and the opposite direction is referred to as the front, and these are collectively referred to as the front-rear direction. In addition, the direction perpendicular to the front-rear direction in the horizontal plane is referred to as the depth direction, and the direction to the left when looking at the rear is referred to as the back side (the back side of the paper in FIG. 1), and the direction to the right side is referred to as the front side (the front side of the paper in FIG. 1).

[0016] The hair implantation net 200 is set so as to cover the net hooking portion 11 of the eccentric 10 from above, and is also in contact with the reversing roller 80 below the pull-out hook 30 to regulate its position. The tip of the hair implantation hook 20 faces backward, and is located at the same height as the rotation axis of the eccentric 10. The tip of the pull-out hook 30 faces upward, and is located below the central axis of the eccentric 10. The thread positioning bar 50 is located below and forward of the take-out port 42 provided at the center in the front-rear direction of the bottom 41 of the stocker 40. The thread drop bar 60 and the thread pull-in bar 70 are located below the thread positioning bar 50 and above the eccentric 10, and forward of the thread positioning bar 50.

[0017] The stocker 40 has a flat bottom 41 that is rectangular in plan view, and a pair of opposing side plates 43 that are provided along each of the two front-rear sides of the bottom 41. The bottom 41 and the side plates 43 are perpendicular, and the cross section in the front-rear direction is U-shaped. The hair material 100a is cut to a length, for example, about twice the length of the hair of the completed wig, and is placed on the bottom 41 of the stocker 40 so as to intersect in the depth direction (for example, most of the hair material 100a that constitutes the hair material bundle 100b is roughly perpendicular to the depth direction). The length of the hair material 100a may be made longer than the length of the bottom 41 of the stocker 40 in the front-rear direction, so that a part of the hair material 100a protrudes outward from the stocker 40. However, it is preferable that the part of the hair material 100a protruding from the storage container 40 does not hang down below the bottom 41, because this prevents the part of the hair material 100a protruding from the storage container 40 from rubbing against the front-to-rear ends of the bottom 41 and becoming damaged when the withdrawal hook 30 captures the hair material 100a from the storage container 40 and pulls it downward, and also prevents the hair material 100a from becoming entangled in other operating mechanisms.

[0018] The stocker 40 may be provided as one as shown in FIG. 2, or may be provided in a plurality of units. Although FIG. 2 illustrates an example in which a plurality of pull-out hooks 30 pull out the hair material 100a from one stocker 40, a single pull-out hook 30 corresponding to each of the plurality of stockers may be configured to pull out the hair material 100a from each of the plurality of stockers. In addition, the stocker 40 is supplied with a mixture of different types of hair materials 100a, such as hair materials 100a of different colors, hair materials 100a of the same color but different thicknesses, and hair materials 100a of the same color or thickness but different hardness (elasticity), and the color, thickness or hair quality of the hair material 100a in the completed wig is adjusted in advance. Note that a single type of hair material 100a may be supplied to the stocker 40.

[0019] The eccentric 10 is a member that secures the implantation area of ​​the hair-implanted net 200, and includes a cylindrical net hanging part 11 having a center line extending in the depth direction, a relief part 12 that is recessed inward from the side peripheral surface of the net hanging part 11 and has an opening that overlaps with the side peripheral surface, and a shaft part 13 that is provided at both ends of the net hanging part 11 and has a center line extending in the depth direction. The center line of the shaft part 13 does not coincide with the center line of the net hanging part 11, but is offset radially outward from the net hanging part 11, and is located on the side peripheral surface of the net hanging part 11 in a portion where the relief part 12 is provided (and further in the circumferential center part of that portion).

[0020] The shaft portion 13 is rotatably supported by a bearing portion (not shown) provided on the device body so that the center line serves as the axis of rotation, and as the shaft portion 13 rotates, the net hanging portion 11 connected to the shaft portion 13 revolves around the center line of the shaft portion 13 as an axis. In the initial position, the opening of the relief portion 12 faces forward as shown in Fig. 1. The center line of the shaft portion 13 may overlap with one weft thread 202-1 located at the circumferential center of the opening of the relief portion 12.

[0021] The opening width (circumferential length) of the escape portion 12 may be determined based on the spacing of the weft threads 202 constituting the mesh of the hair-implanted net 200, for example, when the hair-implanted net 200 is wound around the outer surface of the net hanging portion 11 and one weft thread 202-1 is located at the circumferential center of the opening of the escape portion 12, so that one weft thread 202-2 of two weft threads 202-2 and 202-3 adjacent in the circumferential direction to the one weft thread 202-1 located at the center is located near the lower end of the opening of the escape portion 12, and another weft thread 202-3 is located near the upper end of the opening of the escape portion 12. Note that, although FIG. 1 illustrates a case in which the opening width of the escape portion 12 is narrower than the width of the weft threads 202-2 and 202-3, the opening width of the escape portion 12 may be equal to or greater than the width of the weft threads 202-2 and 202-3.

[0022] The hair implant hook 20 is a member for implanting the hair material 100a in the hair implant net 200, and includes a hook 21 at the tip and a latch 22 for opening and closing the needle mouth of the hook 21. One end of the latch 22 is rotatably connected to the hair implant hook 20 by a shaft (not shown), and by rotating around the shaft, the latch 22 is switched between a state in which the other end of the latch 22 is in contact with the hook 21 and the needle mouth is closed, and a state in which the other end of the latch 22 is separated from the hook 21 and the needle mouth is open. In the initial position, as shown in FIG. 1, the hair implant hook 20 is in a position away from the eccentric 10 in front of the opening of the escape portion 12, and the latch 22 is in a state in which the needle mouth is open.

[0023] The hair implantation hooks 20 are driven by a drive mechanism controlled by the control device, and connect the hair material 100a to the hair implantation net 200 for implantation. The hair implantation hooks 20 are aligned in the depth direction so as to correspond one-to-one with the pull-out hooks 30 shown in Fig. 2. A group of the hair implantation hooks 20 are operated together by a drive mechanism controlled by the control device to implant the hair material 100a into the hair implantation net 200. The number of each of the hair implantation hooks 20 and the pull-out hooks 30 may be one.

[0024] The pull-out hook 30 is a member for capturing the hair material 100a from the stocker 40, and has a hook 31 at its tip capable of capturing one hair material 100a. In the initial position, as shown in FIG. 1, the pull-out hook 30 is located below the eccentric 10 and above the reversing roller 80, and the needle mouth 32 of the hook 31 faces the front side. As shown in FIG. 2, a plurality of pull-out hooks 30 are provided and aligned in the depth direction. A group of a plurality of pull-out hooks 30 operates together by a drive mechanism controlled by a control device to capture the hair material 100a. The hook 31 may be capable of capturing two or more hair materials 100a, and may have any size and shape as long as it can capture the hair material 100a.

[0025] The thread positioning bar 50 is a member that guides the hair material 100a drawn from the stocker 40 by the drawing hook 30 to a predetermined position. As shown in Figs. 1 and 2, the thread positioning bar 50 is generally cylindrical with a center line extending in the depth direction, and a plurality of thread guides 51 recessed from the outer circumferential surface toward the center line are provided around the outer circumferential surface. The thread positioning bar 50 may be provided with both ends in the depth direction fixed to the device body, but if it is supported by the device body in a rotatable state, the thread positioning bar 50 is rotated by the hair material 100a drawn from the stocker 40 by the drawing hook 30, and the hair material 100a can be prevented from being rubbed against the thread guides 51 and damaged. The number of thread guides 51 is the same as the number of drawing hooks 30.

[0026] The thread drop bar 60 is vibrated in the vertical direction by a drive mechanism controlled by the control device, and brushes off the hair material 100a drawn in by the thread pull-in bar 70. The thread pull-in bar 70 is moved in the front-rear direction by a drive mechanism controlled by the control device, and hooks the hair material 100a planted in the hair-implanted net 200 and pulls it forward. The magnet 90 uses magnetic force to attract and open the latch 22 that is closed during the process of planting the hair material 100a in the hair-implanted net 200 with the hair-implanting hook 20. Note that the magnet 90 can be either a permanent magnet or an electromagnet. If it is an electromagnet, it is only necessary to control the electromagnet by the control device to generate magnetic force when opening the closed latch 22, and there is no need to change the relative positional relationship between the hair-implanting hook 20 and the magnet 90. Therefore, the drive mechanism can be simplified by using a configuration in which the hair-implanting hook 20 and the magnet 90 are driven by a common drive mechanism. The reversing roller 80 is rotatably attached to the device body.

[0027] Next, the operation of the automatic hair implantation device will be described with reference to Figures 2 to 21. First, as shown in Figure 2, the thread retraction bar 70 moves backward and stops at a position beyond the outlet 42 of the stocker 40 and the retraction hook 30 to the right in Figure 3 (first operation).

[0028] Next, the pull-out hook 30 rises, and the tip including the hook 31 enters the stocker 40 through the outlet 42, and is further inserted into the hair material bundle 100b, and then lowers and stops (second operation). At this time, the pull-out hook 30 moves slightly toward the front side (the side where the needle port 32 of the hook 31 is open) after the tip is inserted into the outlet 42. As a result, the hair material 100a is hooked on the hook 31 of the pull-out hook 30, and the hair material 100a is pulled out from the outlet 42 of the stocker 40 in a folded state. At this time, both ends of the hair material 100a remain in the stocker 40 as shown in FIG. 3, and the multiple hair materials 100a pulled out folded in two are accommodated one by one in the multiple thread guides 51 of the thread positioning bar 50 as shown in FIG. 5. This restricts each of the pulled out hair materials 100a to a predetermined position, so that the hair implant hook 20 can properly capture the hair material 100a in the subsequent operation.

[0029] Next, as shown in Fig. 4, the hair implantation hook 20 moves backward (third operation). At this time, the hook 21 passes under the weft yarn 202-1, and the needle mouth of the hook 21 is accommodated in the escape portion 12 and reaches the position shown by the dashed line. Next, the hair implantation hook 20 retreats from the position shown by the dashed line to the position shown by the solid line, and the hook 21 hooks the weft yarn 202-1 (fourth operation).

[0030] Next, as shown in Fig. 6, the shaft 13 of the eccentric 10 rotates 90 degrees so that the opening of the relief portion 12 faces upward, and the net hooking portion 11 rotates downward from the position shown by the broken line to the position shown by the solid line about the center line of the shaft 13 and stops (fifth operation). This causes the eccentric 10 to move below the hair implantation hook 20 and the weft 202-1. This movement of the eccentric 10 from the position shown by the broken line to the position shown by the solid line allows the hair implantation hook 20 to pass above the eccentric 10 and reach the hair material 100a that is folded in half between the stocker 40 and the pull-out hook 30. Note that the eccentric 10 may not have the shaft 13 and may rotate about the center line of the net hooking portion 11. In this case, if the hair implant hook 20 is configured to move parallel upward and backward in accordance with the rotation of the net hanging part 11 while keeping the weft thread 202-1 hooked, the hair implant hook 20 will be positioned above the eccentric 10 as described above.

[0031] Next, as shown in Figures 7 and 8, as the hair implantation hook 20 moves backward, the hook 21 approaches the hair material 100a that is folded in half between the stocker 40 and the pull-out hook 30 (sixth operation). At this time, the weft 202-1 passes above the open latch 22, and finally passes through the entire latch 22. Next, the hair implantation hook 20 rotates so that the needle mouth of the hook 21 changes from an upward facing state to a sideways (facing the back side) state (seventh operation). As a result, the needle mouth of the hook 21 faces the hair material 100a pulled out by the pull-out hook 30.

[0032] Next, as shown in Figure 9, the hair implantation hook 20 advances further backwards while the needle opening of the hook 21 is facing sideways, and stops when the needle opening of the hook 21 faces the front part of the folded hair material 100a (hereinafter referred to as the "front part" of the hair material 100a) pulled out by the pull-out hook 30 (8th operation). Next, the pull-out hook 30 moves forward (9th operation). As a result, the front part of the hair material 100a approaches the hair implantation hook 20 and is introduced into the needle opening of the hook 21.

[0033] Next, as shown in Fig. 10, the hair implantation hook 20 rotates so that the needle mouth of the hook 21 faces upward from a state in which it faces sideways, and moves forward as shown in Figs. 11 and 12, so that the latch 22 comes into contact with the weft thread 202-1 and the needle mouth of the hook 21 is closed, and when the hair implantation hook 20 moves from the position shown by the solid line to the position shown by the dashed line, the latch 22 is attracted by the magnetic force of the magnet 90 and the needle mouth of the hair implantation hook 20 is opened (tenth operation). At this time, the hair implantation hook 20 moves away from the hair implantation net 200, so that the front part of the hair material 100a is pulled out slightly from the stocker 40. In addition, the hair material 100a passes from the front side of the outlet 42 through the thread positioning bar 50, between the weft threads 202-1 and 202-2, is folded back at the hook 21, and is deployed so as to pass from the hook 21 between the weft threads 202-1 and 202-2, between the weft threads 202-1 and 202-3, and reach the withdrawal hook 30.

[0034] Next, as shown in Fig. 13, the hair implantation hook 20 moves backward from the position shown by the dashed line in Fig. 11 and rises, and rotates to tie the hair material 100a to the weft 202-1 (11th operation). As a result, two portions of the hair material 100a between the hook 21 and the weft 202-1 are twisted together to form a loop portion 45. Note that in this 11th operation, the raising of the hair implantation hook can be omitted, but by raising it, the hook 21 can be reliably passed through the portion of the hair material 100a between the thread positioning bar 50 and the weft 202-1 in the 12th operation described later.

[0035] Next, as shown in Fig. 14, the hair implantation hook 20 moves toward the front while facing upward, then moves backward, and stops at a position where the needle mouth of the hook 21 is aligned in the depth direction with the rear part of the folded hair material 100a pulled out by the pull-out hook 30 (hereinafter referred to as the "rear part" of the hair material 100a), and rotates so that the needle mouth of the hook 21 faces sideways (facing the back side) from the upward facing state (12th operation). At this time, as shown in Fig. 15, the hook 21 of the hair implantation hook 20 passes through the part between the thread positioning bar 50 and the weft thread 202-1 of the hair material 100a, and the loop portion 45 passes above the latch 22 of the hair implantation hook 20. Furthermore, due to the rotation of the hair implantation hook 20, the needle mouth of the hook 21 faces the rear part of the hair material 100a. The number of rotations of the hair implantation hook 20 may be any number of rotations, such as one rotation, two rotations, or three or more rotations, as long as it is one rotation or more. The direction of rotation may be clockwise or counterclockwise.

[0036] Next, the pull-out hook 30 moves forward (13th operation). As a result, the rear portion of the hair material 100a approaches the hair implantation hook 20 and is introduced into the needle opening of the hook 21. The hair implantation hook 20 may move toward the rear, or both the pull-out hook 30 and the hair implantation hook 20 may move toward each other.

[0037] Next, as shown in Figures 16 and 17, the hair implantation hook 20 rotates so that the needle mouth of the hook 21 faces upward from a state in which it faces sideways, and moves forward, causing the latch 22 to come into contact with the loop portion 45 and closing the needle mouth of the hook 21 (14th operation). This completes the binding of the hair material 100a to the weft yarn 202-1, i.e., the hair implantation. When the hook 21 of the hair implantation hook 20 retreats and passes through the loop portion 45, the pull-out hook 30 may move up and down in small movements to remove the hair material 100a from the hook 31. This makes it possible to prevent peeling, which is a phenomenon in which the hair material 100a shrinks due to friction.

[0038] Next, as shown in Figs. 18 and 19, the thread retracting bar 70 moves forward to retract the front portion of the hair material 100a forward and stops at the initial position (15th operation).

[0039] Furthermore, as shown in FIG. 20, the 16th to 18th operations are performed. First, while the hair implantation hook 20 returns to the initial position and stops, the latch 22 is attracted by the magnetic force of the magnet 90, and the needle mouth of the hair implantation hook 20 is opened (16th operation). The eccentric 10 rotates from the position shown by the solid line in FIG. 6 to the position shown by the broken line in FIG. 6 about the center line of the shaft portion 13 (17th operation). As a result, the opening of the escape portion 12 returns to the initial position facing leftward. The thread drop bar 60 moves downward and then upward and stops at the initial position (18th operation). As a result, the hair material 100a that has completed implantation on the weft yarn 202-1 is shaped downward. Any of the 16th to 18th operations may be performed first, or the 16th to 18th operations may be performed simultaneously.

[0040] With the above operations, one cycle of the operation of implanting the hair material 100a on the weft thread 202-1 in the automatic hair implantation device 120 is completed, and the knot shown in Fig. 21 is created. Note that Fig. 21 illustrates a state in which, in the eleventh operation, the hair implantation hook 20 rotates three times, and the hair material 100a is twisted three times and knotted to the hair implantation net 200.

[0041] In the above-mentioned operation example, the hook 21 of the hair implant hook 20 takes the front part of the hair material 100a in the eighth and ninth operations, and takes the rear part of the hair material 100a in the twelfth and thirteenth operations, but whether the front part or the rear part is taken in each operation, the hair material 100a can be tied to the weft by rotating the hair implant hook 20 one or more times in the twelfth operation. Even if the hair implant hook 20 only rotates half a turn in the twelfth operation, the hair material 100a can be tied to the weft by using the hook 21 of the hair implant hook 20 to take the part that is lowered by the half turn in the twelfth and thirteenth operations.

[0042] <<Configuration of hair material bundle and stocker>> The configurations of the hair material bundle 100b and the stocker 40 will be described below.

[0043] First Embodiment Fig. 22 is a plan view showing the configuration of the hair material bundle 100b and the stocker 40 according to the first embodiment. Fig. 23 is a cross-sectional view taken along line AA in Fig. 22. Fig. 24 is a cross-sectional view of the hair material bundle 100b taken along the short side direction of the hair material bundle 100b. Fig. 25 is a plan view showing the hair material bundle 100b in a state in which the number of hair materials 100a has been reduced.

[0044] As shown in FIG. 22, a plurality of hair material bundles 100b are arranged in the stocker 40. The stocker 40 is formed, for example, in a rectangular shape in a plan view. The stocker 40 has side plates 43 in the front and depth directions. The side plates 43 are connected to the bottom 41. The plurality of hair material bundles 100b are arranged so as to straddle the outlet 42 in the longitudinal direction (front-rear direction) of the hair material bundle 100b. The plurality of hair material bundles 100b are arranged side by side in the depth direction in the stocker 40. Note that FIG. 22 shows an example in which one hair material bundle 100b is arranged with respect to one outlet 42, but one hair material bundle 100b may be arranged with respect to multiple outlets 42, or multiple hair material bundles 100b may be arranged with respect to one outlet 42.

[0045] 22, the hair material bundle 100b includes two bundling members 110 that bundling a plurality of hair materials 100a. One of the two bundling members 110 is disposed in front of the outlet 42, and the other is disposed in the rear of the outlet 42. The two bundling members 110 are disposed at positions that do not overlap with the outlet 42 in a plan view.

[0046] Each of the two bundling members 110 is made of an elastic material. The elastic material may be rubber (natural or synthetic rubber) or plastic. As shown in FIG. 24, the bundling member 110 is formed in a ring shape and presses from the outer periphery 100ba of the hair material bundle 100b toward the inside in the radial direction. The bundling member 110 bundles a plurality of hair materials 100a. As a result, the plurality of hair materials 100a are bundled, so that each hair material bundle 100b can be placed in the stocker 40 (improving handling). The bundling member 110 presses at least the hair material 100a arranged on the outer periphery of the hair material bundle 100b among the plurality of hair materials 100a in a direction perpendicular to the longitudinal direction of the plurality of hair materials 100a. As a result, even if the number of hair materials 100a included in the hair material bundle 100b is reduced, the multiple hair materials 100a are pressed radially inward by the binding member 110. Also, since the upper part of the binding member 110 presses the multiple hair materials 100a downward (reference symbol F1 in FIG. 24), the multiple hair materials 100a are pressed toward the bottom 41 of the stocker 40. Then, as shown in FIG. 25, even if the number of hair materials 100a included in the hair material bundle 100b is reduced, the hair materials 100a are arranged at a position overlapping with the outlet 42 in a plan view.

[0047] 23, the two bundling members 110 are disposed spaced apart in the front-rear direction. As a result, the hair materials 100a among the multiple hair materials 100a other than the hair material 100a pulled out by the pulling hook 30 are pressed (held) by the two bundling members 110. As a result, the pulled out hair material 100a separates from the hair material bundle 100b, while the hair materials 100a other than the pulled out hair material 100a are prevented from jumping out of the outlet 42.

[0048] <Second embodiment> The configuration of the automatic hair implantation device 300 according to the second embodiment will be described with reference to Figures 26 and 27. Figure 26 is a plan view of the stocker 40 of the automatic hair implantation device 300 according to the second embodiment. Figure 27 is a cross-sectional view taken along line BB in Figure 26. Note that the same components as those in the first embodiment are denoted by the same reference numerals and will not be described.

[0049] As shown in FIG. 26, the automatic hair implantation device 300 includes a pressing part 310 and a stocker 340. The pressing part 310 presses a plurality of hair material bundles 100b toward the bottom part 41 as shown in FIG. 27. The stocker 340 includes a lid part 340a. The pressing part 310 includes a contact part 311 and an elastic part 312. The contact part 311 contacts the upper part of the hair material 100a. The elastic part 312 is disposed between the contact part 311 and the lid part 340a, and presses the contact part 311 against the hair material 100a. The contact part 311 may be an elastic member such as rubber or plastic, or may be a metal member. The elastic part 312 may be, for example, a spring member or rubber. As a result, in the second embodiment as well, the hair material 100a other than the hair material 100a pulled out by the pulling hook 30 is pressed by the pressing part 310, so that the hair material 100a can be prevented from jumping out of the outlet 42. The other configurations and effects of the second embodiment are similar to those of the first embodiment.

[0050] <Third embodiment> The configuration of the automatic hair implantation device 400 according to the third embodiment will be described with reference to Fig. 28. Fig. 28 is a diagram showing the configuration of the automatic hair implantation device 400 according to the third embodiment. Note that the same components as those in the first or second embodiment are denoted by the same reference numerals and will not be described.

[0051] As shown in Fig. 28, the automatic hair implantation device 400 includes a pressing part 410. The pressing part 410 includes a contact part 411 and an air cylinder 412. When the hair material 100a is pulled out by the pulling hook 30, the air cylinder 412 presses the contact part 411 against the hair material 100a other than the hair material 100a being pulled out. This makes it possible to prevent the hair material 100a other than the hair material 100a pulled out by the pulling hook 30 from jumping out of the outlet 42 in the third embodiment as well. The other configurations and effects of the third embodiment are similar to those of the first or second embodiment.

[0052] [Variations] As described above, the above-described embodiments are merely examples for implementing the present disclosure. Therefore, the present disclosure is not limited to the above-described embodiments, and can be implemented by appropriately modifying the above-described embodiments without departing from the spirit of the present disclosure.

[0053] (1) In the above first to third embodiments, examples have been shown in which the bundling member or the pressing portion is disposed both in front of and behind the outlet in plan view, but the present disclosure is not limited thereto. For example, as in a hair material bundle 500b according to a modified example shown in Fig. 29, the bundling member 110 may be disposed only in front of the outlet 42, and although not shown, three or more bundling members or pressing portions may be provided per hair material bundle.

[0054] (2) In the above first to third embodiments, an example was shown in which the bundling member or the pressing part pressed the hair material (hair material bundle) toward the bottom (downward), but the present disclosure is not limited thereto. For example, as in the pressing part 610 and the stocker 640 according to a modified example shown in Fig. 30, the pressing part 610 may press the hair material bundle 100b in the depth direction toward the side plate 43 of the stocker 640. In this case, for example, the outlet 642 of the stocker 640 is disposed near the side plate 43. Also, although not shown, if the outlet is provided on the top surface (lid) of the stocker, the pressing part may press the hair material toward the top surface (lid).

[0055] The above-mentioned automatic hair implantation device and the method for adjusting the tension of the hair implantation net can be explained as follows.

[0056] The automatic hair implantation device according to the first configuration comprises a stocker having an outlet and in which multiple hair materials are arranged across the outlet, where some of the multiple hair materials are removed from the outlet by a pulling hook, and a pressing unit that presses at least some of the multiple hair materials in a direction perpendicular to the longitudinal direction of the multiple hair materials, where the pressing unit presses at least some of the multiple hair materials other than the hair material pulled out from the stocker (first configuration).

[0057] According to the above-mentioned first configuration, the pressing portion presses at least a portion of the hair material other than the hair material being pulled out of the stocker, thereby preventing the other hair materials from protruding from the outlet due to being dragged by friction with the hair material being pulled out of the stocker.

[0058] In the first configuration, the outlet may be formed in the bottom of the stocker, and the pressing portion may be configured to press at least a portion of the hair material other than the hair material being pulled out of the stocker toward the bottom of the stocker (second configuration).

[0059] According to the second configuration, the hair material other than the hair material being pulled out from the stocker can be prevented from protruding from the outlet while the hair material is pressed toward the outlet, thereby preventing the hair material from being lost to the pulling hook.

[0060] In the first or second configuration, the pressing portion may be configured to press a hair material bundle made up of a plurality of hair materials from an outer periphery of the hair material bundle toward a radially inward direction (third configuration).

[0061] According to the third configuration, the multiple hair materials in the hair material bundle are pressed against each other, so that it is possible to prevent some of the multiple hair materials from popping out of the outlet.

[0062] In the third configuration, the pressing portion may include an elastic member that binds the bundle of hair material (fourth configuration).

[0063] According to the fourth configuration, by using the elastic member, it is possible to easily press the hair material bundle from the outer periphery toward the radially inward direction. Also, since the hair material bundle is bound, each hair material bundle can be placed in the stocker (improving handling).

[0064] In any one of the first to fourth configurations, the pressing portion may include a one-side pressing member arranged on one longitudinal side of the outlet, and an other-side pressing member arranged on the other longitudinal side of the outlet (fifth configuration).

[0065] According to the fifth configuration, at least a portion of the multiple hair materials can be pressed on each of both longitudinal sides of the multiple hair materials, thereby further preventing a portion of the multiple hair materials from flying out of the outlet.

[0066] A hair material bundle for an automatic hair implantation device according to a sixth configuration comprises a stocker having an outlet and in which multiple hair materials are arranged across the outlet, and some of the multiple hair materials are removed from the outlet by a withdrawal hook, the hair material bundle for an automatic hair implantation device comprising a stocker, the stocker comprising a multiple hair materials arranged in the stocker, and an elastic member that ties the multiple hair materials together (sixth configuration).

[0067] According to the sixth configuration, the elastic member presses at least a part of the hair material other than the hair material being pulled out of the stocker, thereby preventing the other hair materials from protruding from the outlet due to being dragged by friction with the hair material being pulled out of the stocker.
