Description

[Technical Field]

[0001] The present invention relates to a brushing device. [Background technology]

[0002] Conventionally, natural hair has been reproduced by bundling hair of the same length into a hair bundle and then shifting the ends of the hair by brushing the bundle (for example, Patent Document 1). For example, in the hair transplantation method of Patent Document 1, an operator bundles hair cut to the same length into a bundle, and then manually brushes the bundle using a hair combing machine to shift the ends of the hair. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4756689 Summary of the Invention [Problem to be solved by the invention]

[0004] In the hair transplantation method of Patent Document 1, when brushing the hair bundles, the worker manually brushes the hair bundles using a hair combing machine. Therefore, it takes time to brush the hair bundles, and there is a problem that the quality of the hair bundles after brushing varies depending on the skill of the worker.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a brushing device that is less susceptible to individual variations in quality due to differences in the skill of the operator than conventional brushing devices. [Means for solving the problem]

[0006] One aspect of the present invention for solving the above problem is a brushing device that shifts the position of the ends of a hair bundle by brushing, the brushing device comprising: a support part having a plurality of protrusions that inserts the plurality of protrusions into gaps between the hairs that make up the hair bundle to support one end of the hair bundle; a moving means that moves the support part in the longitudinal direction of the hair bundle so that the protrusions move from the center of the hair bundle to pass over one end of the hair; and a clamping mechanism having a first clamping part and a second clamping part that clamps the hair bundle with the first clamping part and the second clamping part, the clamping mechanism forming a plurality of types of enclosed spaces with different cross-sectional areas perpendicular to the longitudinal direction of the hair bundle with the first clamping part and the second clamping part, and during the brushing operation, the clamping mechanism clamps the hair bundle to store the hair bundle in a plurality of enclosed spaces, and the moving means moves the support part.

[0007] According to this aspect, brushing can be performed by moving the protrusions of the support part, so brushing can be performed regardless of the skill of the operator. Therefore, individual differences due to differences in skill among operators are less likely to occur compared to conventional methods. According to this aspect, the clamping mechanism uses the first clamping part and the second clamping part to form a plurality of types of enclosed spaces with different cross-sectional areas perpendicular to the longitudinal direction of the hair bundle, and during the brushing operation, the clamping mechanism clamps the hair bundle to store the hair bundle in the plurality of enclosed spaces, and the moving means moves the support part having the protrusions 61. This prevents the protrusions from passing through only the same position on the hair bundle in the width direction.

[0008] In a preferred aspect, the first clamping portion has a plurality of first recesses having different depths and / or widths, and the plurality of types of enclosed spaces includes a concave enclosed space formed by the first recesses and the second clamping portion.

[0009] In a preferred aspect, the second clamping portion has a plurality of second recesses having different heights and / or widths, and the recessed enclosed space is formed by the first recesses and the second recesses.

[0010] A preferred aspect is to have a holding part that holds a held part belonging to the middle part of the hair bundle, and during the brushing operation, the clamping mechanism divides the hair bundle into multiple enclosed spaces, and the holding part holds the held part.

[0011] The above aspects may be made dependent on each other, or some of the configurations may be quoted or substituted for each other, as long as they are included in the technical scope of the present invention. [Effects of the Invention]

[0012] According to the present invention, individual differences due to differences in worker skill are less likely to occur compared to the prior art. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments of the present invention will be described in detail.

[0015] The brushing device 301 of the first embodiment of the present invention performs a brushing operation to brush a hair bundle 100 made up of a plurality of hairs, thereby shifting the positions of the hair ends. The brushing device 301 includes a main body 2, a holding part 3, a stand 4, and a mixing part 305, as shown in FIGS.

[0016] (Main body 2) As shown in FIG. 3, the main body 2 is a V-shaped part in a side view, and includes a pair of brushing parts 10 and 11.

[0017] The brushing parts 10 and 11 are parts for combing the hair bundle 100, and are inclined from the end on the holding part 3 side to the opposite end with a horizontal component and a vertical component. That is, the first brushing part 10 slopes downward from the rear end (the end on the holding part 3 side) to the front end in the front-to-back direction Y, and the second brushing part 11 slopes downward from the front end (the end on the holding part 3 side) to the rear end in the front-to-back direction Y.

[0018] When viewed from the side, the inclination angle θ1 (the angle of the straight line connecting the centers of the gear parts 30a, 31a (30b, 31b)) of the brushing parts 10, 11 relative to the horizontal plane shown in Figure 3 exceeds 0 degrees, and is preferably 15 degrees or more, more preferably 30 degrees or more, and even more preferably 45 degrees or more. The inclination angle θ1 of the brushing parts 10 and 11 shown in FIG. 3 is less than 90 degrees, preferably 80 degrees or less, and more preferably 75 degrees or less. In the following description, the direction of the straight line connecting the centers of the gear parts 30a and 31a (30b and 31b) is referred to as the tilt direction.

[0019] The brushing units 10 and 11 are provided with a moving means 15 (first moving means, second moving means) and a support unit 16, as shown in FIGS.

[0020] The moving means 15 is a part that moves the support part 16 in one direction, and specifically is a chain conveyor. As shown in FIGS. 1 and 3, the moving means 15 includes upper gear portions 30a and 30b, lower gear portions 31a and 31b, chain portions 32a and 32b, a connecting shaft portion 33, and a power source .

[0021] The upper gear portions 30a, 30b, 31a, 31b are rotational force transmission portions, specifically sprockets, that engage with parts of the chain portions 32a, 32b and transmit rotational force to the chain portions 32a, 32b to convert it into moving force. The upper gear portions 30a, 30b are provided on the central side (holding portion 3 side) at a distance from the lower gear portions 31a, 31b in the front-to-back direction Y, and are provided above the lower gear portions 31a, 31b in the up-down direction Z.

[0022] The chain portion 32a (32b) is a portion that endlessly suspends between the gear portions 30a, 31a (30b, 31b), and is specifically a roller chain.

[0023] The connecting shaft portion 33 is a portion that connects the central axes of the upper gear portions 30a, 30b and synchronizes them.

[0024] The power source 35 is a geared motor having a rotatable shaft portion, and the shaft portion is connected to the lower gear portion 31a, so that the power source 35 can rotate the lower gear portion 31a. That is, the moving means 15 rotates the lower gear portion 31a by driving the power source 35, and as the lower gear portion 31a rotates, the upper gear portion 30a rotates via the chain portion 32a, and as the upper gear portion 30a rotates, the upper gear portion 30b rotates synchronously via the connecting shaft portion 33, and as the upper gear portion 30b rotates, the lower gear portion 31b rotates via the chain portion 32b.

[0025] As the gear parts 30a, 30b, 31a, and 31b rotate, the chain parts 32a and 32b synchronize with each other and rotate so as to surround the chain parts 32a and 32b. That is, as the gear parts 30a, 30b, 31a, and 31b rotate, the moving means 15 moves the upper parts of the chain parts 32a and 32b in a direction away from the holding part 3 (the direction in which the chain parts 32a and 32b move) and moves the lower parts of the chain parts 32a and 32b in a direction toward the holding part 3, with the gear parts 30a, 30b, 31a, and 31b as references.

[0026] As shown in FIG. 3, the support part 16 includes a support main body part 21, a plurality of pin holder parts 22, and a lifting part 23.

[0027] The support body 21 is a part that supports the hair bundle 100 from below in a planar manner, and is configured by arranging a plurality of support plate parts 50 side by side. The support plate parts 50 of the support main body 21 are arranged at intervals in the extension direction of the chain parts 32a, 32b, and are located on the same plane above the chain parts 32a, 32b. That is, in the support main body 21, a support surface that supports the hair bundle 100 from below is formed by the support plate parts 50 above the chain parts 32a, 32b.

[0028] 2, the support plate portion 50 is a plate-like body extending in the left-right direction X so as to connect between the chain portions 32a, 32b that are arranged in parallel with a gap in the left-right direction X. That is, both ends of the support plate portion 50 in the longitudinal direction (left-right direction X) are fixed to the chain portions 32a, 32b, respectively.

[0029] As shown in FIG. 2, the pin holder 22 is a group of projections having a plurality of projections 61, and includes a base 60 and the projections 61. The base portion 60 is a plate-like portion that is placed on the support plate portion 50 and fixed to the support plate portion 50, as shown in FIG. The protrusion 61 is a protrusion that protrudes in a direction perpendicular to the base portion 60 and has a sharp tip. As shown in FIG. 2(b), the protrusions 61 are provided on the base portion 60 so as to be distributed in a planar manner. The height of the protrusion 61 is preferably 30 mm or more and 300 mm or less.

[0030] As shown in FIG. 2(b), the pin holder 22 has a plurality of widthwise projection groups 62a, 62b, which are arranged in parallel at intervals in the width direction (inclined direction). The width direction protrusion groups 62a, 62b of this embodiment are configured by a plurality of protrusions 61 arranged at intervals in the left-right direction X, and in this embodiment, the plurality of protrusions 61 are arranged at equal intervals in the left-right direction X. As shown in Figure 2(b), each convex portion 61 constituting the widthwise convex portion group 62a is shifted in the left-right direction X relative to each convex portion 61 constituting the widthwise convex portion group 62b adjacent to it in the inclined direction, and the convex portion 61 of the widthwise convex portion group 62a is positioned between adjacent convex portions 61, 61 of the widthwise convex portion group 62b in the width direction of the pin holder portion 22.

[0031] The lifting portion 23 is a part that lifts a part of the hair bundle 100 so that the convex portion 61 of the pin holder portion 22 passes through the gaps in the hair bundle 100, and has a base portion 70 and a pressing piece portion 71 as shown in Figure 3. The base portion 70 is a plate-like portion that is placed on the support plate portion 50 and fixed to the support plate portion 50 . The pressing piece 71 is a part that presses the hair bundle 100 and forms a space between the hair bundle 100 and the pin holder part 22, and is a protruding piece that protrudes in an arc shape from the base part 60 as shown in FIG. The height of the lifting portion 23 (height from the support plate portion 50 to the top of the pressing piece portion 71) is preferably equal to or greater than the height of the pin holder portion 22 (height from the support plate portion 50 to the tip of the convex portion 61).

[0032] (Holding part 3) The holding part 3 is a part that holds the middle part of the hair bundle 100 so that the hair bundle 100 cannot move in the longitudinal direction, and is also a conveying part that conveys the hair bundle 100 in the front-rear direction Y. The holding unit 3 has a first roll 80 and a second roll 81 as shown in FIG.

[0033] The first roll 80 is a feed roll that feeds the hair bundle 100 in the front-rear direction Y. The rotation speed of the first roll 80 is adjustable, and it can rotate forward to send the hair bundle 100 to the first brushing section 10 side, and rotate backward to send the hair bundle 100 to the second brushing section 11 side.

[0034] The second roll 81 is a roll that forms a pair with the first roll 80 and is aligned with the first roll 80 in the vertical direction Z. The second roll 81 is a nipping roll that nip the hair bundle 100 together with the first roll 80, and applies nip pressure to the hair bundle 100. The second roll 81 is movable between a close state in which it is close to the first roll 80 and a separated state in which it is separated from the first roll 80. The holding unit 3 clamps the hair bundle 100 by bringing the second roll 81 into a close proximity state, and allows the first roll 80 to feed the hair bundle 100 in the longitudinal direction by bringing the second roll 81 into a separated state.

[0035] (Standing part 4) The mount part 4 is a support mount that supports the holding part 3, and as shown in FIG. 1, includes a base part 90 and support parts 91a and 91b. The support pillars 91a and 91b are erected on the base 90 and are capable of supporting the rolls 80 and 81 of the holder 3.

[0036] (Mixing section 305) The mixing section 305 is a section that mixes the hair bundle 100 by shifting it in the left-right direction X, and includes a first uneven section 311 and a second uneven section 312 as shown in FIG. The mixing section 305 is a clamping mechanism that clamps the hair bundle 100 between the first uneven section 311 and the second uneven section 312, and is capable of shifting the hair bundle 100 in the left-right direction X. That is, the mixing section 305 is movable between a close position where the second uneven section 312 is relatively close to the first uneven section 311 and a distant position where the second uneven section 312 is relatively far from the first uneven section 311, and in the close position, the first uneven section 311 and the second uneven section 312 can clamp the hair bundle 100.

[0037] As shown in FIG. 4, the first concave-convex portion 311 has a first base portion 320 and a first partition portion 321. The first base portion 320 is a plate-like portion that has a width in the front-rear direction Y and extends in the left-right direction X. The first partition portion 321 is a convex portion that protrudes upward from the first base portion 320, and is a plate-shaped convex strip portion that has a width in the left-right direction X, a thickness in the up-down direction Z, and extends in the front-to-back direction Y. The first uneven portion 311 has first partitions 321 with different widths, and in this embodiment, the widths of the first partitions 321 are different. In the first uneven portion 311, the height (thickness) of the first partition portion 321 from the first base portion 320 is the same. In the first uneven portion 311, the first partition portions 321 are arranged at intervals in the left-right direction X. The first uneven portion 311 has a plurality of types of intervals between the first partitions 321, 321 adjacent in the left-right direction X, and in this embodiment, the intervals between the first partitions 321, 321 adjacent in the left-right direction X are different from one another.

[0038] From another perspective, the first uneven portion 311 has a plurality of first recesses 322. The first recess 322 is a recessed groove having the first base portion 320 as its bottom and the adjacent first partition portions 321, 321 as its inner walls, and has a depth downward. The first concave-convex portion 311 has a plurality of different widths in the left-right direction X of the first recesses 322, and in this embodiment, the widths of the first recesses 322 in the left-right direction X are different from one another. In the first uneven portion 311, the first recesses 322 all have the same depth.

[0039] The second uneven portion 312 is a clamping portion that pairs with the first uneven portion 311 and clamps the hair bundle 100 together with the first uneven portion 311. The second uneven portion 312 has a second base portion 330 and a plurality of second partition portions 331 . The second base portion 330 is a plate-like portion that has a width in the front-rear direction Y and extends in the left-right direction X. The second partition portion 331 is a convex portion that protrudes downward from the second base portion 330, and is a plate-shaped convex strip portion that has a width in the left-right direction X, a thickness in the up-down direction Z, and extends in the front-to-back direction Y. The second uneven portion 312 has second partitions 331 with different widths, and in this embodiment, the widths of the second partitions 331 are different. In the second uneven portion 312, the height (thickness) of the second partition portion 331 from the second base portion 330 is the same. In the second uneven portion 312, the second partition portions 331 are arranged at intervals in the left-right direction X. The second uneven portion 312 also has a plurality of different intervals between the second partitions 331, 331 adjacent in the left-right direction X, and in this embodiment, the intervals between the second partitions 331, 331 adjacent in the left-right direction X are different from one another.

[0040] From another perspective, the second concave-convex portion 312 has a plurality of second concave portions 332 . The second recess 332 is a recessed groove having the first base portion 320 as its bottom and the adjacent second partition portions 331, 331 as its inner walls, and has a depth toward the upper side. The second concave and convex portions 312 have a plurality of different widths in the left-right direction X of the second recesses 332, and in this embodiment, the widths of the second recesses 332 in the left-right direction X are different from one another. In the second uneven portion 312, the second recesses 332 all have the same depth.

[0041] Here, if we pay attention to the positional relationship between each part of the first uneven portion 311 and the second uneven portion 312, the first uneven portion 311 is located in a position where at least one first partition portion 321 overlaps with the second partition portion 331 of the second uneven portion 312 in the vertical direction Z. Furthermore, the first uneven portion 311 is located such that at least one first recess 322 overlaps with a second recess 332 in the vertical direction Z. That is, when the second uneven portion 312 is in a close proximity position relative to the first uneven portion 311, as shown in Figure 4(b), the first partition portion 321 of the first uneven portion 311 and the second partition portion 331 of the second uneven portion 312 abut against each other, and the first partition portion 321 of the first uneven portion 311 does not enter the second recess 332 of the second uneven portion 312.

[0042] When the mixing section 305 is brought into a close proximity position as shown in Figure 4(b), at least one continuous enclosed space 340 is formed between the first recess 322 of the first uneven section 311 and the second recess 332 of the second uneven section 312. When the mixing section 305 is in the close proximity position, at least one continuous enclosed space 341 is formed between the first partition section 321 of the first uneven section 311 and the second recess 332 of the second uneven section 312. When the mixing section 305 is in the close proximity position, at least one continuous enclosed space 342 (concave enclosed space) is formed between the first recess 322 of the first uneven section 311 and the second partition section 331 of the second uneven section 312. That is, when the mixing section 305 is in the close position, a plurality of surrounding spaces 340 to 342 that surround the hair bundle 100 are formed as shown in FIG. 4(b).

[0043] (100 hair strands) The hair bundle 100 is a bundle of hair such as artificial hair, human hair, or animal hair. The hairs constituting the hair bundle 100 may be of the same length or of different lengths, as long as they have a certain length. Of the hairs constituting the hair bundle 100, the shortest hair preferably has a length of 100 mm or more and 3000 mm or less. The hairs constituting the hair bundle 100 may be crimped.

[0044] Next, the positional relationship between the components of the brushing device 301 according to the first embodiment of the present invention will be described.

[0045] 3, the brushing device 301 has a first brushing unit 10 and a second brushing unit 11 that face each other in the front-to-back direction Y with the holding unit 3 and the mixing unit 305 sandwiched between them, and the first brushing unit 10 and the second brushing unit 11 are arranged in a V-shape. That is, the first brushing unit 10 and the second brushing unit 11 are spaced apart in the front-to-back direction Y from the top end to the bottom end. The mixing portion 305 is disposed between the holding portion 3 and the first brushing portion 10 and / or between the holding portion 3 and the second brushing portion 11. In the support part 16, the lifting part 23 and each of the pin holders 22 are fixed onto the support plate part 50 of the support main body part 21, and the lifting part 23 and each of the pin holders 22 are arranged in this order in the traveling direction of the chain parts 32a and 32b. In the support part 16, the lifting part 23 and each of the pin holders 22 are arranged with a gap between them in the traveling direction of the chain parts 32a and 32b.

[0046] Next, an example of a method for brushing the hair bundle 100 using the brushing device 301 according to the first embodiment of the present invention will be described.

[0047] The brushing operation of the brushing device 301 of this embodiment is mainly composed of a position adjustment step, a holding step, a combing step, a mixing step, and a moving step. The brushing operation of this embodiment involves performing a first combing operation in which a position adjustment operation, a holding operation, and a combing operation are performed in this order, and after the first combing operation, a second combing operation in which a mixing operation, a combing operation, and a holding operation are performed in this order, and a third combing operation in which a moving operation, a holding operation, and a combing operation are performed in this order, alternately, one or more times. After the first combing operation, the second combing operation may be performed first, or the third combing operation may be performed first. The number of times of the second combing action and the number of times of the third combing action are not particularly limited, but are preferably 2 times or more and 10 times or less.

[0048] (Position adjustment process) The position adjustment process is a process that is mainly carried out before the holding process, and is a process of adjusting the position of each of the spike portions 22 and lifting portions 23 of each brushing portion 10, 11, and positioning the hair bundle 100 so that it straddles the support portion 16 of each brushing portion 10, 11. Specifically, the position adjustment process is a process in which the support surface on the upper side of each brushing part 10, 11 is adjusted to be composed of multiple support plate parts 50, and the worker positions the hair bundle 100 so that it straddles the support surface of the brushing parts 10, 11. In the position adjusting step, the power source 35 is driven to move the chain parts 32a and 32b so that the pin holder part 22 is positioned on the lower side of each of the brushing parts 10 and 11. In addition, if the pin holder 22 is originally located at the lower side of each brushing part 10, 11, it is not necessary to move the chain parts 32a, 32b.

[0049] At this time, the lower gear portion 31a is rotated by the power source 35, which rotates the chain portion 32a, and the upper gear portion 30a is rotated in response to the rotation of the chain portion 32a. In addition, the rotation of the upper gear portion 30a causes the upper gear portion 30b to rotate via the connecting shaft portion 33, and the rotation of the upper gear portion 30b causes the chain portion 32b to rotate, which in turn causes the lower gear portion 31b to rotate. In this way, in each brushing section 10, 11, the chain sections 32a, 32b run synchronously as the lower gear section 31a rotates due to the power source 35, so that on the upper side, each support plate section 50 moves from the upper side to the lower side in the inclined direction, as shown by the arrows in Figure 5(a), and on the lower side, each support plate section 50 moves from the lower side to the upper side in the inclined direction.

[0050] (holding process) The holding step is a step carried out before the combing step, in which the held portion 110 located in the middle of the hair bundle 100 is held by the holding portion 3. In the holding step, the second roll 81 is moved from the separated state to the close state as indicated by the arrow in FIG. 5(b), and the held portion 110 of the hair bundle 100 is sandwiched between the first roll 80 and the second roll 81.

[0051] At this time, the second roll 81, in the close proximity state, presses the held portion 110 of the hair bundle 100 toward the first roll 80, and the hair bundle 100 is unable to move in the longitudinal direction. In other words, even if the power source 35 is driven to advance the chain portions 32a and 32b, the held portion 110 of the hair bundle 100 does not move in the advancing direction of the chain portions 32a and 32b.

[0052] (combing process) The combing step is a step that is mainly carried out after the holding step described above or the mixing step described below, and is a step of brushing the hair bundle 100 and shifting the ends of the hair bundle 100. 6, in a state in which the held portion 110 is clamped between the rolls 80, 81 of the holding unit 3, the power source 35 is driven in the first brushing unit 10, and the support unit 16 is moved so that the convex portion 61 of the pin holder 22 moves from the center side (the held portion 110 side) of the hair bundle 100 past the hair ends on the front side. Also, in the combing process, the power source 35 is driven in the second brushing unit 11 simultaneously with or at a different timing from the first brushing unit 10, and the support unit 16 is moved so that the convex portion 61 of the pin holder 22 moves from the center side (the held portion 110 side) of the hair bundle 100 past the hair ends on the rear side.

[0053] At this time, in each brushing part 10, 11, as shown in Figure 6, the lifting part 23, which is ahead of the pin holder part 22 in the movement direction of the support plate part 50 (the movement direction of the chain parts 32a, 32b), scoops up the hair bundle 100 upward, and causes the convex part 61 of the pin holder part 22 to enter the gap between the hair bundle 100 and the support surface, and passes through the gaps between the hairs of the hair bundle 100. As a result, the hair bundle 100 is positioned above the convex part 61, and the tip of the convex part 61 pierces the hair bundle 100, so the convex part 61 passes through the gaps between the hairs of the hair bundle 100 smoothly without tangling the hair, and the convex part 61 divides the hair bundle 100 into multiple parts. At this time, the hair bundle 100 is clamped and restricted by the rolls 80, 81 of the holder 3, and therefore does not move in the longitudinal direction (the direction in which the chain parts 32a, 32b move). In the combing process of this embodiment, the power sources 35 of the brushing units 10 and 11 are driven simultaneously, so that the gear units 30a, 30b, 31a, and 31b rotate at the same speed, and the chain units 32a and 32b move in the same direction. As a result, both ends of the hair bundle 100 are brushed simultaneously with the same force.

[0054] In the combing step, the number of times the leading pin holder part 22 passes over the hair bundle 100, that is, the number of rotations of each brushing part 10, 11, is not particularly limited, but is preferably between 2 and 10 times.

[0055] (Mixing process) In the mixing step, the second roll 81 is moved from the close state to the separated state, and the second roll 81 is separated upward from the held portion 110, allowing the hair bundle 100 to have some freedom of movement. Next, as shown in Figure 7, the first uneven portion 311 and the second uneven portion 312 are brought close to each other, and the hair bundle 100 is clamped by the first uneven portion 311 (first clamping portion) and the second uneven portion 312 (second clamping portion), and a portion of the hair bundle 100 is surrounded by surrounding spaces 340-342 formed by the first partition portion 321 and / or the first recess 322 of the first uneven portion 311 and the second partition portion 331 and / or the second recess 332 of the second uneven portion 312. As a result, the hair bundle 100 is divided into multiple bundles with different cross-sectional areas by the enclosed spaces 340-342 formed by the first uneven portion 311 and the second uneven portion 312, and the hair spreads and mixes in the left-right direction X, so that the hair bundle 100 as a whole spreads in the left-right direction X.

[0056] (Moving process) The moving step is a step carried out in the third combing operation, and is a step that is mainly carried out before the second or subsequent combing steps. The moving step is a step of moving the held part 110 clamped by the rolls 80, 81 of the holding part 3 in the front-rear direction Y onto the support surface of the first brushing part 10 or the second brushing part 11. In the moving step, as shown in Fig. 8(a), the second roll 81 is moved from a close state to a separated state, and the second roll 81 is moved upward away from the held portion 110, allowing the hair bundle 100 to have some freedom of movement. Next, as shown in Fig. 8(b), the first roll 80 is rotated to move the hair bundle 100 in the front-to-back direction Y, and the held portion 110 is placed on the support surface of the first brushing part 10 (or the second brushing part 11).

[0057] According to the brushing device 301 of this embodiment, brushing can be performed by moving the convex portion 61 with the moving means 15, so brushing can be performed regardless of the skill of the operator. Therefore, compared to conventional methods, individual differences in quality due to differences in the skill of the operator are less likely to occur. According to the brushing device 301 of this embodiment, the hair bundle 100 is supported in a planar manner by the support part 16, so that the hair bundle 100 is appropriately distributed on the support part 16, and the convex part 61 can easily pass through the gaps between the hairs in the hair bundle 100, allowing for smooth brushing.

[0058] According to the brushing device 301 of this embodiment, the support part 16 has a support main body part 21 that is inclined with a vertical component and a horizontal component, and a protrusion part 61 that stands upright relative to the support main body part 21. Therefore, the support part 16 spreads due to the weight of the hair bundle 100, and the protrusion part 61 can easily pass through gaps between the hairs in the hair bundle 100.

[0059] According to the brushing device 301 of this embodiment, the support part 16 has a plurality of protrusions 61 of the pin holder part 22 distributed at intervals in a planar manner. Therefore, the protrusions 61 can be passed over the hair bundle 100 evenly.

[0060] According to the brushing device 301 of this embodiment, the support part 16 has widthwise projection groups 62a (62b) in which projections 61 are arranged at intervals in the width direction (left-right direction X) of the hair bundle 100, and the hairs constituting the hair bundle 100 pass between the projections 61 of the widthwise projection groups 62a (62b). Therefore, the projections 61 can pass through the hair bundle 100 more evenly.

[0061] According to the brushing device 301 of this embodiment, the brushing unit 10 uses the moving means 15 (first moving means) to move the support unit 16 so that the convex portion 61 (first convex portion) moves from the center of the hair bundle 100 past one end of the hair, and the brushing unit 11 uses the moving means 15 (second moving means) to move the support unit 16 so that the convex portion 61 (second convex portion) moves from the center of the hair bundle 100 past the other end of the hair. Therefore, the brushing units 10 and 11 can brush both end sides of the hair bundle 100. This reduces the brushing time compared to conventional methods. According to the brushing device 301 of this embodiment, the brushing unit 10 supports one hair tip side of the hair bundle 100 in a planar manner using the support unit 16 (first support unit), and the brushing unit 11 supports the other hair tip side of the hair bundle 100 in a planar manner using the support unit 16 (second support unit). Therefore, the hairs are appropriately distributed on the support units 16, 16 at each hair tip side, and the convex portions 61, 61 can easily pass through gaps between the hairs of the hair bundle 100.

[0062] According to the brushing device 301 of this embodiment, with the hair bundle 100 stretched across the support part 16 of the brushing part 10 and the support part 16 of the brushing part 11, the support part 16 of the brushing part 10 is moved horizontally in a direction away from the support part 16 of the brushing part 11. Therefore, the ends of each hair of the hair bundle 100 can be brushed separately or simultaneously.

[0063] According to the brushing device 301 of this embodiment, the holding part 3 that holds the held part 110 that belongs to the middle part of the hair bundle 100 can send the held part 110 to a position where it overlaps with the convex part 61 of the brushing part 10 or the convex part 61 of the brushing part 11. Therefore, the held part 110 can also be brushed with the brushing part 10 or the brushing part 11. Furthermore, according to the brushing device 301 of this embodiment, the first roll 80 can move the hair bundle 100 toward each brushing section 10, 11, so the hair bundle 100 can be brushed in stages. For example, the hair can be brushed in separate areas such as the ends, middle, and back of the hair.

[0064] According to the brushing device 301 of this embodiment, the held portion 110 of the hair bundle 100 can be sandwiched and held by the rolls 80, 81 of the holding unit 3, and by rotating the first roll 80 and / or the second roll 81, the held portion 110 is sent to a position where it overlaps with the support portion 16 of the brushing unit 10 or the support portion 16 of the brushing unit 11. Therefore, the held portion 110 can be easily brushed.

[0065] According to the brushing device 301 of this embodiment, in the position adjustment process, the support surface on the upper side of each brushing part 10, 11 is adjusted to be composed of multiple support plate parts 50, and the worker positions the hair bundle 100 so that it straddles the support surface of the brushing parts 10, 11, so that when the hair bundle 100 is set up, the hair bundle 100 does not get tangled in the convex part 61 and is easy to set up.

[0066] According to the brushing device 301 of this embodiment, the mixing section 305 forms a plurality of types of enclosed spaces 340-342 with different cross-sectional areas perpendicular to the longitudinal direction of the hair bundle 100 by using the first uneven section 311 and the second uneven section 312, and during the brushing operation, the mixing section 305 holds the hair bundle 100 and stores it in the plurality of enclosed spaces 340-342, and the moving means 15 moves the support section 16 having the convex portions 61. This prevents the convex portions 61 from passing through only the same position on the hair bundle 100 in the width direction.

[0067] According to the brushing device 301 of this embodiment, the enclosed spaces 340-342 formed by the first uneven portion 311 and the second uneven portion 312 include recessed enclosed spaces 340-342 that include at least a recess of either the first uneven portion 311 or the second uneven portion 312. Therefore, a part of the hair bundle 100 is easily enclosed by the recessed enclosed spaces 340-342.

[0068] According to the brushing device 301 of this embodiment, the enclosed spaces 340-342 formed by the first uneven portion 311 and the second uneven portion 312 include a concave enclosed space 340 formed by the first recess 322 of the first uneven portion 311 and the second recess 332 of the second uneven portion 312. Therefore, a portion of the hair bundle 100 is more likely to be enclosed by the concave enclosed space 340.

[0069] According to the brushing device 301 of this embodiment, in the brushing operation, the mixing part 305 divides the hair bundle 100 into a plurality of enclosed spaces 340-342, and the holding part 3 holds the held part 110. Therefore, in the combing process, the hair bundle 100 can be prevented from returning to the position before being surrounded by the mixing part 305.
