Description

[Technical Field]

[0001] The present invention relates to an automatic hair implantation device. [Background technology]

[0002] BACKGROUND ART Conventionally, automatic hair implantation devices that tie hair materials to an object to be implanted and implant them have been known. Such automatic hair implantation devices are disclosed in, for example, Patent Document 1.

[0003] The automatic hair implantation device of Patent Document 1 includes a storage container that stores hair material bundles made up of multiple hair materials and has an outlet at the bottom, a first hook, and a second hook. The second hook pulls out the hair material from the outlet of the storage container. The first hook then captures the pulled out hair material, and then ties the hair material to a hair implantation net and implants it. [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 with the hair material pulled out from the outlet by the second hook may cause parts of hair materials in the stocker other than the hair material in question to protrude out of the outlet. Furthermore, the first hook may fail to capture the hair material pulled out by the second hook. Hair materials that fail to be captured are not implanted and part of them protrude out of the outlet. Such hair materials that protrude out of the outlet may interfere with other hair materials or with equipment in the automatic hair implantation device, causing poor hair implantation.

[0006] Therefore, the inventors of the present application considered using two teeth to clamp and collect unwanted hair materials (hereinafter referred to as "protruding hair materials") that protrude partially from the outlet. However, because the shapes and positions of the unwanted hair materials protruding from the outlet are not uniform, it is difficult to clamp the protruding hair materials with the two teeth, making it difficult to collect the protruding hair materials.

[0007] The present invention has been made to solve the above-mentioned problems, and aims to provide an automatic hair implantation device that can collect unwanted hair material protruding from the removal outlet of the stocker. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the automatic hair implantation device disclosed below comprises: a stocker in which a plurality of hair materials are placed, the stocker having an outlet through which some of the plurality of hair materials are removed; a withdrawal hook that captures and pulls out some of the plurality of hair materials from the outlet; and a hair material recovery unit having two teeth that clamp and recover protruding hair materials, which are at least one of the following hair materials: hair materials other than those captured by the withdrawal hook, with a portion protruding from the outlet toward the withdrawal hook; and hair materials captured by the withdrawal hook, with a portion protruding from the outlet toward the withdrawal hook without being implanted in the hair implantation object; and the hair material recovery unit includes a guide portion shaped to guide the protruding hair materials between the two teeth. [Effects of the Invention]

[0009] According to the above configuration, the protruding hair material can be guided between the two teeth by the guide portion, so that the protruding hair material can be easily clamped by the two teeth. As a result, unnecessary protruding hair material protruding from the outlet of the stocker can be collected. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[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 modifications can be made within the scope of the configuration of the present invention. In the following description, the same reference numerals are used in different drawings for identical parts or parts having similar functions, and repeated description thereof will be omitted. The configurations described in the embodiment and modified examples may be combined or modified as appropriate. To facilitate understanding of the description, the drawings referred to below show simplified or schematic configurations, and some components may be omitted.

[0012] <<Configuration and operation example of automatic hair transplantation device>> First, the basic configuration and operation of an automatic hair implantation device according to an embodiment of the present invention will be described with reference to the drawings. Note that, as a prerequisite for explaining the essential parts of the present invention, only one example of the basic configuration and operation of the automatic hair implantation device will be described. Naturally, it is 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 essential 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 shown in Fig. 1, viewed 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, a pull-out 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. Under the control of the drive mechanism by the control device, the eccentric 10, the hair implantation hook 20, the pull-out 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, thereby capturing hair material 100a one by one from the stocker 40 and tying it to the weft yarn 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 a plurality of warp threads 201 and a plurality of weft threads 202, and each of the warp threads 201 and the weft threads 202 may be a single thread made by twisting together a plurality of raw threads, 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 pre-cut hair materials 100a is placed in a stocker 40 located above the eccentric 10. A pull-out hook 30 is located below an outlet 42 of the stocker 40, and the eccentric 10 is located between the hair implantation hook 20 and the pull-out hook 30. Hereinafter, the direction in the horizontal plane toward the pull-out hook 30 as viewed from the eccentric 10 will be referred to as the rear, and the opposite direction as the front, and these directions will be collectively referred to as the front-to-rear direction. Furthermore, the direction perpendicular to the front-to-rear direction in the horizontal plane will be referred to as the depth direction, and the direction to the left when looking back will be referred to as the back side (the back side of the paper in FIG. 1), and the direction to the right side will be referred to as the front side (the front side of the paper in FIG. 1).

[0016] The flocked net 200 is set so as to cover the net hooking portion 11 of the eccentric 10 from above, and its position is also regulated by contact with a reversing roller 80 below the pull-out hook 30. The tip of the flocked net 20 faces backward and is located at approximately 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 opening 42 provided in the center of the bottom 41 of the stocker 40 in the front-to-rear direction. 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-to-rear sides of the bottom 41. The bottom 41 and side plates 43 are perpendicular, and the cross section in the front-to-rear direction is U-shaped. The hair material 100a is cut to a length, for example, approximately twice the length of the hair of the completed wig, and placed on the bottom 41 of the stocker 40 so that it intersects with the depth direction (for example, most of the hair material 100a that make up the hair material bundle 100b is generally perpendicular to the depth direction). Note that the length of the hair material 100a may be longer than the length of the bottom 41 of the stocker 40 in the front-to-rear direction, so that a portion of the hair material 100a protrudes outward from the stocker 40. However, it is preferable that the portion of the hair material 100a protruding from the stocker 40 does not hang down below the bottom 41, because this prevents the portion of the hair material 100a protruding from the stocker 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 stocker 40 and pulls it out downward, and also prevents the hair material 100a from getting caught in other operating mechanisms.

[0018] As shown in FIG. 2, only one stocker 40 may be provided, or multiple stockers may be provided. While FIG. 2 illustrates an example in which multiple pull-out hooks 30 pull out hair materials 100a from one stocker 40, multiple stockers may be configured so that one pull-out hook 30 pulls out hair materials 100a from each stocker. 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), may be mixed and supplied to the stocker 40, and the color, thickness, or texture of the hair materials 100a in the completed wig may be adjusted in advance. A single type of hair material 100a may be supplied to the stocker 40.

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

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

[0021] The opening width (circumferential length) of the relief portion 12 may be determined based on the spacing between the weft threads 202 that form the mesh of the hair-implanted net 200, for example, when the flocked net 200 is wrapped 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 relief portion 12, so that one weft thread 202-2 of two weft threads 202-2 and 202-3 that are circumferentially adjacent to the centrally located weft thread 202-1 is located near the lower end of the opening of the relief portion 12, and the other weft thread 202-3 is located near the upper end of the opening of the relief portion 12. Note that while Fig. 1 illustrates a case where the opening width of the relief portion 12 is narrower than the width of the weft threads 202-2 and 202-3, the opening width of the relief 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 component for implanting the hair material 100a into the hair implant net 200, and includes a hook 21 at its tip and a latch 22 for opening and closing the needle opening 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 switches between a state in which the other end of the latch 22 is in contact with the hook 21 and the needle opening is closed, and a state in which the other end of the latch 22 is separated from the hook 21 and the needle opening is open. In the initial position, as shown in Figure 1, the hair implant hook 20 is located in front of the eccentric 10 and in a position facing the opening of the relief portion 12, and the latch 22 is in a state in which the needle opening 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 implant 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 Figure 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 implant net 200. Note that there may be only one hair implantation hook 20 and one pull-out hook 30.

[0024] The pull-out hook 30 is a member that captures the hair material 100a from the stocker 40, and is provided with a hook 31 at its tip that can capture one hair material 100a. In its initial position, as shown in FIG. 1, the pull-out hook 30 is located below the eccentric 10 and above the reversing roller 80, with the needle port 32 of the hook 31 facing forward. As shown in FIG. 2, a plurality of pull-out hooks 30 are provided and aligned in the depth direction. A group of the 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 be of any size or 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 pulled out from the stocker 40 by the pulling hook 30 to a predetermined position. As shown in Figures 1 and 2, the thread positioning bar 50 is generally cylindrical with a centerline extending in the depth direction, and multiple thread guides 51 recessed from the outer periphery toward the centerline are provided around the outer periphery. The thread positioning bar 50 may be provided with both ends in the depth direction fixed to the device body, but if it is rotatably supported by the device body, the thread positioning bar 50 will be rotated by the hair material 100a pulled out from the stocker 40 by the pulling hook 30, preventing the hair material 100a from rubbing against the thread guides 51 and being damaged. The number of thread guides 51 is the same as the number of pulling hooks 30.

[0026] The thread drop bar 60 is vibrated vertically by a drive mechanism controlled by the control device and removes the hair material 100a pulled in by the thread retraction bar 70. The thread retraction bar 70 is moved back and forth by a drive mechanism controlled by the control device and hooks the hair material 100a implanted in the hair implant net 200, pulling it forward. The magnet 90 magnetically attracts and opens the latch 22 that is closed during the process of implanting the hair material 100a into the hair implant net 200 with the hair implantation hook 20. The magnet 90 can be either a permanent magnet or an electromagnet. However, if the magnet 90 is an electromagnet, the magnetic force only needs to be generated when the electromagnet is controlled by the control device to open the closed latch 22. This eliminates the need to change the relative positions of the hair implantation hook 20 and the magnet 90. Therefore, the drive mechanism can be simplified by driving the hair implantation hook 20 and the magnet 90 with 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 rearward and stops at a position beyond the outlet 42 of the stocker 40 and the retraction hook 30 on the right side in Figure 3 (first operation).

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

[0029] Next, as shown in Figure 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 opening of the hook 21 is housed in the escape portion 12 and reaches the position shown by the dashed line. Next, the hair implantation hook 20 moves back 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 Figure 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 about the center line of the shaft 13 from the position shown by the dashed line to the position shown by the solid line 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 dashed line to the position shown by the solid line enables the hair implantation hook 20 to pass above the eccentric 10 and reach the hair material 100a that has been folded in half between the stocker 40 and the pull-out hook 30. Note that the eccentric 10 may not have a 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 hooking 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] 7 and 8, as the hair implantation hook 20 moves backward, the hook 21 approaches the hair material 100a folded in half between the stocker 40 and the pull-out hook 30 (sixth operation). At this time, the weft yarn 202-1 passes above the open latch 22 and eventually passes through the entire latch 22. Next, the hair implantation hook 20 rotates so that the needle opening of the hook 21 changes from facing upward to facing sideways (toward the back) (seventh operation). As a result, the needle opening 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 moves further backward while keeping the needle port of the hook 21 facing sideways, and stops when the needle port of the hook 21 faces the front part of the folded hair material 100a pulled out by the pull-out hook 30 (hereinafter referred to as the "front part" of the hair material 100a) (eighth operation). Next, the pull-out hook 30 moves forward (ninth operation). As a result, the front part of the hair material 100a approaches the hair implantation hook 20 and is introduced into the needle port of the hook 21.

[0033] 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, causing the latch 22 to come into contact with the weft yarn 202-1 and closing the needle mouth of the hook 21. When the hair implantation hook 20 moves further 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 opens (tenth operation). At this time, the hair implantation hook 20 moves away from the hair implantation net 200, and the front portion 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, passes between the weft threads 202-1 and 202-2, is folded back at the hook 21, and is unfolded so that it passes from the hook 21 between the weft threads 202-1 and 202-2, passes between the weft threads 202-1 and 202-3, and reaches the withdrawal hook 30.

[0034] Next, as shown in Figure 13, the hair implantation hook 20 moves backward from the position indicated by the dashed line in Figure 11 and rises, and rotates to tie the hair material 100a to the weft 202-1 (11th operation). As a result, the 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 sure to pass through the portion of the hair material 100a between the thread positioning bar 50 and the weft 202-1 in the 12th operation described below.

[0035] Next, as shown in Figure 14, the hair implantation hook 20 moves toward the front while facing upward, then moves backward, stopping when the needle point of the hook 21 is aligned in the depth direction with the rear portion of the folded hair material 100a pulled out by the pull-out hook 30 (hereinafter referred to as the "rear portion" of the hair material 100a), and rotates so that the needle point of the hook 21 faces sideways (facing the back side) from the upward position (twelfth operation). At this time, as shown in Figure 15, the hook 21 of the hair implantation hook 20 passes through the portion of the hair material 100a between the thread positioning bar 50 and the weft thread 202-1, and the loop portion 45 passes above the latch 22 of the hair implantation hook 20. Furthermore, as a result of the rotation of the hair implantation hook 20, the needle point of the hook 21 faces the rear portion of the hair material 100a. The number of rotations of the hair implantation hook 20 may be any number of rotations, such as one, two, or three or more rotations, as long as it is one or more rotations. 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 close the needle mouth of the hook 21 (14th operation). This completes the tying of the hair material 100a to the weft yarn 202-1, i.e., the hair implantation. Note that when the hook 21 of the hair implantation hook 20 moves back and passes through the loop portion 45, the withdrawal hook 30 may move up and down in small movements to release the hair material 100a from the hook 31. This prevents peeling, which is frizz caused by friction of the hair material 100a.

[0038] Next, as shown in Figures 18 and 19, the thread retracting bar 70 moves forward, retracting the front portion of the hair material 100a forward and stopping at the initial position (fifteenth operation).

[0039] Furthermore, as shown in FIG. 20, operations 16 to 18 are performed. First, while the hair implantation hook 20 returns to its initial position and stops, the latch 22 is attracted by the magnetic force of the magnet 90, opening the needle mouth of the hair implantation hook 20 (operation 16). The eccentric 10 rotates around the center line of the shaft 13 from the position indicated by the solid line in FIG. 6 back to the position indicated by the dashed line in FIG. 6 (operation 17). This returns the opening of the escape portion 12 to its initial position facing left. The thread drop bar 60 moves downward and then upward and stops at its initial position (operation 18). This allows the hair material 100a, which has been completely implanted on the weft yarn 202-1, to be styled downward. Note that any of operations 16 to 18 may be performed first, or operations 16 to 18 may be performed simultaneously.

[0040] The above operations complete one cycle of the operation of the automatic hair implantation device 120 to implant the hair material 100a to the weft thread 202-1, and the knot shown in Figure 21 is created. Note that Figure 21 illustrates the state in the eleventh operation where the hair implantation hook 20 rotates three times and the hair implantation thread 100 is twisted three times and tied to the hair implantation net 200.

[0041] In the above-described example of the operation, the hook 21 of the hair implant hook 20 grabs the front portion of the hair material 100a in the eighth and ninth operations, and grabs the rear portion of the hair material 100a in the twelfth and thirteenth operations, but whether the front or rear portion is grabbed 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. Also, 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 grab the lower portion of the hair material 100a that has been rotated half a turn in the twelfth and thirteenth operations.

[0042] <<Configuration and operation for collecting protruding hair material>> The configuration and operation for collecting the protruding hair material 100d will be described below.

[0043] First Embodiment Fig. 22A is a diagram showing the configuration of the hair material collecting unit 150 of the automatic hair implantation device 120 according to the first embodiment. Fig. 22B is a schematic diagram showing the state in which the protruding hair material 100d is captured. As shown in Fig. 22A, the automatic hair implantation device 120 according to the first embodiment includes the hair material collecting unit 150. The hair material collecting unit 150 includes a capturing mechanism unit 110, a storage unit 130, and a suction unit 140.

[0044] (Configuration of the capture mechanism) 18, 20, and 22A, the capturing mechanism 110 clamps and collects protruding hair material 100d, which is hair material other than the hair material 100a captured by the withdrawal hook 30 and which has a portion (portion 100da) protruding from the outlet 42 toward the withdrawal hook 30. In this case, the protruding hair material 100d moves to a position where it cannot be captured by the withdrawal hook 30 because the portion 100da protrudes from the outlet 42 toward the withdrawal hook 30, and is therefore unnecessary hair material that will not be used for hair implantation. Also, as shown in FIG. 22B, the capturing mechanism 110 clamps and collects protruding hair material 100d, which is hair material captured by the withdrawal hook 30 and which remains without being implanted in the hair implant net 200 with the protruding portion 100db protruding from the outlet 42 toward the withdrawal hook 30. In this case, the protruding hair material 100d is a hair material that failed to be captured by the hair implantation hook 20 and remains below the outlet 42 while being captured by the extraction hook 30. Because this protruding hair material 100d remains below the outlet 42 while being captured by the extraction hook 30, it is an unnecessary hair material that may interfere with other hair materials 100a or the equipment. In addition, the capturing mechanism 110 is disposed below the outlet 42.

[0045] FIG. 23A is a cross-sectional view of the capturing mechanism 110 in the direction in which the hair material 100a is pulled out. FIG. 23B is a cross-sectional view of the capturing mechanism 110 in the rearward direction. FIG. 24A is a view of the hair material 100a being clamped by the teeth 111a and 111b in the pulling direction. FIG. 24B is a view of the hair material 100a being clamped by the teeth 111a and 111b in the rearward direction. As shown in FIG. 23A, the capturing mechanism 110 includes a plurality of teeth 111a and 111b, a first base member 112a, a second base member 112b, and a plurality of guide members 113a and 113b. In the automatic hair implantation device 120, one tooth 111a and one tooth 111b are provided for each of the plurality of outlets 42. The plurality of teeth 111a extend forward from the first base member 112a. The plurality of teeth 111b extend forward from the second base member 112b. For example, the plurality of teeth 111a extend in parallel. The plurality of teeth 111b extend in parallel.

[0046] As shown in FIG. 23A, guide members 113a and 113b are arranged on the tooth portions 111a and 111b, respectively. The guide members 113a and 113b are shaped to guide the protruding hair material 100d between the tooth portions 111a and 111b. Specifically, the guide members 113a and 113b are provided with inclined surfaces 114a and 114b, respectively. The inclined surfaces 114a and 114b are arranged at the tip portions of the tooth portions 111a and 111b, respectively. The inclined surfaces 114a and 114b are inclined with respect to the depth direction so as to face each other. As a result, in a plan view, the guide members 113a and 113b have shapes that gradually increase in size from D1 to D2 in the direction of travel of the capturing mechanism portion 110. The space between the inclined surfaces 114a and 114b is connected to the space between the tooth portions 111a and 111b (the portion that clamps the protruding hair material 100d). As a result, when the tooth portions 111a and 111b move toward the protruding hair material 100d, the protruding hair material 100d can be guided into the gap between the guide members 113a and 113b, which have a shape in which the gap between the tooth portions 111a and 111b gradually increases in the direction of movement. Since the gap between the guide members 113a and 113b is connected to the gap between the tooth portions 111a and 111b, the protruding hair material 100d can be guided from the gap between the guide members 113a and 113b into the gap between the tooth portions 111a and 111b. Note that the "inclined surface" is not limited to a surface with a constant inclination angle (flat surface), but may be an arc-shaped (R-shaped) inclined surface.

[0047] The guide members 113a and 113b are each made of an elastic material, such as a thermoplastic resin such as polypropylene, or alternatively, synthetic rubber or natural rubber.

[0048] As shown in Fig. 23B, the guide member 113a is formed in a cylindrical shape that covers the outer periphery of the tooth portion 111a. The guide member 113b is formed in a cylindrical shape that covers the outer periphery of the tooth portion 111b. This makes it possible to easily attach the guide members 113a and 113b (cylindrical portions) to the tooth portions 111a and 111b, respectively. Furthermore, since the outer periphery of each of the tooth portions 111a and 111b is covered with an elastic member, the protruding hair material 100d can come into contact with the elastic member even if it approaches either the tooth portion 111a or 111b from any direction.

[0049] The guide member 113a has a circular cross section perpendicular to the direction in which the tooth portion 111a extends. The guide member 113b has a circular cross section perpendicular to the direction in which the tooth portion 111b extends. The tooth portions 111a and 111b have rectangular cross sections perpendicular to the direction in which they extend. As a result, as shown in FIG. 23B, a portion of the outer surface of the tooth portion 111a is separated from a portion of the inner surface of the guide member 113a, and a space CL1 is formed between a portion of the outer surface of the tooth portion 111a and a portion of the inner surface of the guide member 113a. A portion of the outer surface of the tooth portion 111b is separated from a portion of the inner surface of the guide member 113b, and a space CL2 is formed between the outer surface of the tooth portion 111b and the inner surface of the guide member 113b. As a result, as shown in Fig. 24B, when the tooth portions 111a and 111b clamp the protruding hair material 100d, the guide member 113a bends toward the space CL1, and the guide member 113b bends toward the space CL2. This increases the contact area where the tooth portions 111a and 111b clamp the protruding hair material 100d. Furthermore, even when the tooth portions 111a and 111b clamp multiple protruding hair materials 100d, the guide members 113a and 113b can elastically deform to clamp each of the multiple protruding hair materials 100d.

[0050] Fig. 25 is a schematic diagram showing a state in which the protruding hair material 100d is guided between the tooth portions 111a and 111b by the guide members 113a and 113b. As shown in Fig. 25, when the tooth portions 111a and 111b move toward the protruding hair material 100d, the protruding hair material 100d moves between the tooth portions 111a and 111b along the inclined surfaces 114a and 114b of the guide members 113a and 113b. With the protruding hair material 100d positioned between the tooth portions 111a and 111b, the distance between the tooth portions 111a and 111b is reduced, thereby clamping the protruding hair material 100d between the tooth portions 111a and 111b. As a result, the protruding hair material 100d can be guided between the tooth portions 111a and 111b by the guide members 113a and 113b, and the protruding hair material 100d can be easily collected by the tooth portions 111a and 111b.

[0051] (Configuration of the first base member and the second base member) As shown in FIG. 23B, the second base member 112b is disposed overlapping the first base member 112a in a direction (e.g., vertical direction) perpendicular to the direction in which the tooth portions 111a and 111b are arranged. The first base member 112a and the second base member 112b are moved forward (direction A1 in FIG. 23A) or backward (direction A2 in FIG. 23A) by reciprocating mechanisms 115a and 115b, respectively. As a result, the first base member 112a and the second base member 112b move relatively in the A1 or A2 direction. For example, as shown in FIG. 24A, the first base member 112a moves in the A1 direction while the second base member 112b moves in the A2 direction, thereby narrowing the gap between the tooth portions 111a and 111b. As a result, the protruding hair material 100d is clamped between the tooth portions 111a and 111b. Furthermore, as the first base member 112a moves in the A2 direction and the second base member 112b moves in the A1 direction, the gap between the tooth portion 111a and the tooth portion 111b becomes larger, and the clamped protruding hair material 100d falls into the storage section 130, as shown in Figure 22A.

[0052] As shown in Fig. 23A, the reciprocating motion mechanisms 115a and 115b are fixed to a base member 116a. The base member 116a is driven by a reciprocating motion mechanism 116b, such as an air cylinder, to move forward or backward. This causes the capture mechanism section 110 to reciprocate between the initial position shown in Figs. 1 and 20 and a position below the outlet 42 shown in Fig. 18 or 22B (hereinafter referred to as the "capture position"). Note that the reciprocating motion mechanism 116b may include a rack and pinion instead of an air cylinder.

[0053] (Configuration of the storage section) 22A, the storage unit 130 is formed in the shape of a box or tray without a lid, and temporarily stores a plurality of protruding hair materials 100d. The storage unit 130 stores a plurality of protruding hair materials 100d collected by the capturing mechanism unit 110. The storage unit 130 is also arranged below the initial positions of the teeth 111a and 111b of the capturing mechanism unit 110, and the protruding hair materials 100d released from the teeth 111a and 111b fall, thereby being stored in the storage unit 130. A bottom surface 131 of the storage unit 130 is also provided with a plurality of suction ports 132, and the plurality of suction ports 132 are arranged below the initial positions of the teeth 111a and 111b.

[0054] (Configuration of suction part) As shown in Fig. 22A, the suction unit 140 sucks the protruding hair materials 100d in the storage unit 130 and discharges them from the storage unit 130 to the outside. The suction unit 140 includes a connecting member 141, an ejector 142, and a cutting member 143. The connecting member 141 is formed, for example, in a tubular shape, and allows the protruding hair materials 100d to pass through its interior. The connecting member 141 has a plurality of openings 141a connected to the plurality of suction ports 132, respectively. The connecting member 141 connects the suction ports 132 to the discharge ports 140a through which the protruding hair materials 100d are discharged.

[0055] The ejector 142 compresses gas to a pressure higher than atmospheric pressure (air pressure inside the storage section 130) and releases the compressed gas from the supply port 141b of the connecting member 141 toward the discharge port 140a, causing air to flow from the multiple suction ports 132 toward the discharge port 140a. This causes suction at the multiple suction ports 132, causing the protruding hair materials 100d inside the storage section 130 to enter the connecting member 141. The gas released by the ejector 142 may be air, but other gases (such as nitrogen) may also be used. In the first embodiment, the provision of the ejector 142 simplifies the configuration of the hair material recovery section 150 and allows the protruding hair materials 100d to be sucked in, compared to when a rotating electric machine such as a blower is provided. For example, if an air compressor is installed in a factory, the air compressor (a general-purpose air compressor) may be used.

[0056] The cutting member 143 is disposed within the connecting member 141. The cutting member 143 includes blades that cut the protruding hair material 100d that moves within the connecting member 141. The multiple blades rotate or move in parallel to cut the protruding hair material 100d.

[0057] The hair material collecting section 150 includes a discharged material storing section 160 that stores the protruding hair materials 100d discharged from the discharge port 140a. A user of the automatic hair implantation device 120 collects the protruding hair materials 100d in the discharged material storing section 160 and reuses the collected protruding hair materials 100d for hair implantation or discards them. The discharged material storing section 160 may be configured to be detachable from the hair material collecting section 150 in any manner.

[0058] (Operation of the capture mechanism and suction unit) Next, a description will be given of the operations of the capture mechanism part 110 and the suction part 140. Fig. 26 is a flow chart showing the control process of the capture mechanism part 110 and the suction part 140 by the control device 95.

[0059] As shown in Fig. 26, in step S1, the teeth 111a and 111b of the capturing mechanism part 110 are moved (advanced) from the initial position to a position (capturing position) below the outlet 42. For example, as shown in Fig. 6, after the hair material 100a is extracted from the outlet 42 by the pulling hook 30 (after the second operation), the teeth 111a and 111b are moved to the capturing position. Note that the teeth 111a and 111b move from the initial position to the capturing position while the gap between the teeth 111a and 111b is open (see Fig. 25). At this time, the guide members 113a and 113b position the protruding hair material 100d between the teeth 111a and 111b.

[0060] In step S2, the teeth 111a and 111b are closed to clamp the protruding hair material 100d. For example, as shown in Fig. 18 or 22B, after the entire hair material 100a being implanted is taken out from the stocker 40 (for example, after the 14th operation), the teeth 111a and 111b are closed to clamp the protruding hair material 100d.

[0061] In step S3, the teeth 111a and 111b move from the capturing position to the initial position while holding the protruding hair material 100d between them. For example, as shown in Fig. 20, the teeth 111a and 111b move to a position above the storage section 130 while holding the protruding hair material 100d between them.

[0062] In step S4, suction by suction unit 140 is started. That is, suction by suction unit 140 is stopped until step S3. Note that this example is not limiting, and step S4 may be started during the period in which step S2 is being executed, or during the period in which step S3 is being executed.

[0063] In step S5, as shown in Fig. 22A, the teeth 111a and 111b open, and the clamped protruding hair material 100d falls into the storage section 130. The fallen protruding hair material 100d is sucked into the connecting member 141 through the suction port 132 of the storage section 130. Then, the protruding hair material 100d is cut by the cutting member 143, and then discharged into the discharged material storage section 160 through the discharge port 140a.

[0064] In step S6, the suction by the suction unit 140 is stopped, and the process returns to step S1. As a result, even if a protruding hair material 100d occurs, the protruding hair material 100d is collected and discharged from the storage unit .

[0065] Second Embodiment The configuration of the automatic hair implantation device 300 according to the second embodiment will be described with reference to Fig. 27. Fig. 27 is a diagram for explaining the configuration of the automatic hair implantation device 300 according to the second embodiment.

[0066] As shown in FIG. 27, the automatic hair implantation device 300 includes a suction unit 340 and a discharge material storage unit 360. The suction unit 340 includes a connecting member 341, a blower 342, and a filter material 343. The connecting member 341 is a passage connecting the suction port 132 and the discharge port 140a. The blower 342 sucks the protruding hair materials 100d through the suction port 132 by rotating its impeller. The filter material 343 is disposed between the suction port 132 and the blower 342 and captures the protruding hair materials 100d. The filter material 343 is made of nonwoven fabric or has a mesh-like structure and is configured to allow air to pass through while capturing solids such as the protruding hair materials 100d. The discharge material storage unit 360 stores the protruding hair materials 100d captured by the filter material 343. According to the configuration of the second embodiment, unlike the case where an ejector is provided, even if a device for releasing gas (e.g., an air compressor) is not provided in a factory or the like where the automatic hair implantation device 300 is installed, the protruding hair material 100d can be sucked in by the blower 342. Note that other configurations and effects are the same as those of the first embodiment.

[0067] [Variations] 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 within the scope of the present disclosure.

[0068] (1) In the first and second embodiments, examples have been described in which a cylindrical guide member is attached to the teeth portion, but the present disclosure is not limited to this. For example, as in a capture mechanism 410 according to a first modification shown in Fig. 28, hat-shaped (cap-shaped) guide members 413a and 413b may be provided at the tip end of each of the teeth portions 111a and 111b. The guide members 413a and 413b are provided with portions 414a and 414b, respectively, whose spacing gradually decreases toward the space between the teeth portions 111a and 111b.

[0069] (2) In the first and second embodiments, the guide portion and the teeth portion are configured as separate members, but the present disclosure is not limited to this. For example, as in a capture mechanism 510 according to a second modified example shown in Fig. 29, inclined surfaces 514a and 514b may be formed on the tips of the teeth portions 511a and 511b, respectively. In this case, the inclined surfaces 514a and 514b function as guide portions.

[0070] (3) In the first and second embodiments, the distal end surface of the guide member is formed as an inclined surface, but the present disclosure is not limited to this. For example, as in a capture mechanism 610 according to a third modified example shown in FIG. 30, the side surface of the guide member 613a may be formed as an inclined surface 614a.

[0071] (4) In the first and second embodiments, examples were shown in which inclined surfaces were formed on all of the guide members, but the present disclosure is not limited to this. For example, as in a capture mechanism 710 according to a fourth modified example shown in Fig. 31, some of the guide members 713a may not be provided with inclined surfaces.

[0072] (5) In the first and second embodiments, the suction unit sucks the protruding hair material housed in the housing unit, but the present disclosure is not limited thereto. For example, as in the automatic hair implantation device 800 according to the fifth modified example shown in FIG. 32, the suction unit 840 may suck the protruding hair material 100d arranged between the tooth portions 111a and 111b. In this case, the connecting member 841 may move together with the tooth portions 111a and 111b, or may be fixed at the initial position of the tooth portions 111a and 111b. When the connecting member 841 moves together with the tooth portions 111a and 111b, the connecting member 841 is made of a flexible member.

[0073] (6) In the first and second embodiments, the guide member is made of an elastic material, but the present disclosure is not limited to this. For example, the guide member may be made of a material that is hardly elastically deformable (e.g., a metal material).

[0074] (7) In the first and second embodiments, the cross section of the guide member is circular and the cross section of the teeth portion is rectangular, but the present disclosure is not limited to this. For example, the cross section of the guide member may be rectangular, elliptical, or polygonal, and the cross section of the teeth portion may be circular, elliptical, or polygonal.

[0075] (8) In the first and second embodiments, an example in which a suction unit is provided is shown, but the present disclosure is not limited to this. For example, the protruding hair material accumulated in the storage unit may be collected by the user.

[0076] (9) In the first and second embodiments, as shown in Fig. 22B, the capture mechanism is disposed immediately below the outlet (in the vicinity of the outlet), but the present disclosure is not limited to this. For example, as in the capture mechanism 910 according to the sixth modified example shown in Fig. 33, the capture mechanism may be disposed between the outlet 42 and the pull-out hook 30 and below the hair implantation hook 20 (in the vicinity of the pull-out hook 30).

[0077] The automatic hair transplantation device can be explained as follows.

[0078] The automatic hair implantation device according to the first configuration comprises a stocker in which a plurality of hair materials are placed, the stocker having an outlet through which some of the plurality of hair materials are removed; a withdrawal hook that captures and pulls out some of the plurality of hair materials from the outlet; and a hair material recovery unit having two teeth that clamp and recover at least one of the following protruding hair materials: hair materials other than those captured by the withdrawal hook, which have a portion protruding from the outlet toward the withdrawal hook, and hair materials captured by the withdrawal hook that have not been implanted in the hair implantation object and remain with a portion protruding from the outlet toward the withdrawal hook; and the hair material recovery unit includes a guide portion shaped to guide the protruding hair material between the two teeth (first configuration).

[0079] According to the first configuration, the guide portion can guide the protruding hair material between the two teeth, so that the protruding hair material can be easily clamped between the two teeth, thereby making it easy to collect the protruding hair material.

[0080] In the first configuration, the two tooth portions may be configured to clamp the protruding hair material in a direction intersecting the direction in which the pulling hook pulls out some of the multiple hair materials, and as the pulling hook advances toward the protruding hair material or after it has advanced, and the guide portion may include a pair of portions having a shape in which the distance between them gradually increases toward the advancing direction when viewed in the pulling out direction, and the gap between the pair of portions may be connected to the gap between the two tooth portions (second configuration).

[0081] According to the second configuration, when the two teeth move toward the protruding hair material, the protruding hair material can be guided into the gap between the pair of parts, which have a shape in which the distance between them gradually increases in the direction of movement. Furthermore, since the gap between the pair of parts is connected to the gap between the two teeth, the protruding hair material can be guided from the gap between the pair of parts into the gap between the two teeth.

[0082] In the second configuration, the pair of portions of the guide part may have a pair of inclined parts that face each other when viewed in the pulling-out direction (third configuration).

[0083] According to the third configuration, when the protruding hair material hits one of the pair of inclined portions, it can be guided along the inclined portion that hits it into the gap between the two tooth portions.

[0084] In any one of the first to third configurations, the guide portion may include an elastic member disposed at a position of the two teeth that clamps at least the protruding hair material (fourth configuration).

[0085] According to the fourth configuration, even when there are multiple protruding hair materials, the shape of the elastic member deforms to fit the bundle of multiple protruding hair materials, so that the multiple protruding hair materials can be captured more reliably.

[0086] In the fourth configuration, the elastic member may be configured to have two cylindrical portions that cover the outer peripheries of the two tooth portions, respectively (fifth configuration).

[0087] According to the fifth configuration, the cylindrical portion can be easily attached to each of the two teeth. Furthermore, since the outer periphery of each of the two teeth is covered with the elastic member, the protruding hair material can come into contact with the elastic member even if the protruding hair material approaches the teeth from any direction.

[0088] In the fifth configuration, the two cylindrical portions may be spaced apart from the two tooth portions at positions where the two tooth portions clamp the protruding hair material (sixth configuration).

[0089] According to the sixth configuration, the gap between the tooth portion and the cylindrical portion can function as a cushion, so that the cylindrical portion can be elastically deformed to a greater extent.

[0090] In the sixth configuration, at least one of the two tooth portions may have a rectangular cross-section perpendicular to the direction in which the tooth portion extends, and the cylindrical portion covering the outer periphery of at least the tooth portion having a rectangular cross-section of the two cylindrical portions may have a circular cross-section perpendicular to the direction in which the tooth portion extends (seventh configuration).

[0091] According to the seventh configuration, a gap (space) can be easily formed between the tooth portion and the cylindrical portion in a direction perpendicular to the direction in which the tooth portion extends.

[0092] In any one of the fourth to seventh configurations, the hair material collecting unit may further include a first base member having one of the two tooth portions formed thereon, a second base member having the other of the two tooth portions formed thereon, the second base member being arranged overlapping the first base member in a direction perpendicular to the direction in which the two tooth portions are aligned, and a base member mechanism unit that moves the first base member and the second base member relative to each other so that the two tooth portions approach each other (eighth configuration).

[0093] According to the eighth configuration, by moving the base member mechanism part relatively, it is possible to easily switch between a state in which the protruding hair material is clamped by the two tooth parts and a state in which the protruding hair material is released.
