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 side 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 beyond one end side; and a shear force generating means that generates a widthwise shear force on the hair bundle and moves the hairs of the hair bundle in the width direction, wherein during the brushing action, the hairs of the hair bundle are moved in the width direction by the shear force generating means, 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, in the brushing operation, the hairs of the hair bundle are moved in the width direction by the shear force generating means that generates a shear force in the width direction of the hair bundle, and the support part is moved by the moving means, so that it is possible to prevent the protrusions from passing only at the same position on the hair bundle in the width direction.

[0008] In a preferred aspect, the shear force generating means has a first friction plate portion and a second friction plate portion, and generates a shear force by clamping the hair bundle between the first friction plate portion and the second friction plate portion and moving the first friction plate portion and the second friction plate portion relatively in the width direction.

[0009] In a preferred aspect, the hair straightening device has a holding part that holds a held part belonging to a middle part of the hair bundle, In the brushing operation, the shear force generating means moves the hairs of the hair bundle in the width direction, and the holding portion holds the held portion.

[0010] 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]

[0011] According to the present invention, individual differences in quality due to differences in worker skill are less likely to occur than in the past. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present invention will be described in detail.

[0014] The brushing device 1 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 1 includes a main body 2, a holding part 3, a stand 4, and a mixing part 5, as shown in FIGS.

[0015] (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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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 .

[0020] The gear portions 30a, 30b, 31a, and 31b are rotational force transmission portions, specifically sprockets, that engage with parts of the chain portions 32a and 32b and transmit rotational force to the chain portions 32a and 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.

[0021] 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.

[0022] The connecting shaft portion 33 is a portion that connects the central axes of the upper gear portions 30a, 30b and synchronizes them.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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).

[0031] (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.

[0032] 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.

[0033] 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.

[0034] (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.

[0035] (Mixing section 5) The mixing section 5 is a section that mixes the hair bundle 100 by shifting it in the left-right direction X, and specifically, is a shear force generating means that generates a shear force in the left-right direction X on the hair bundle 100 to mix it by shifting it in the left-right direction X. As shown in FIG. 1, the mixer 5 includes a first friction plate portion 101 and a second friction plate portion 102, and the friction plate portions 101 and 102 are arranged to face each other in the vertical direction Z. The mixing section 5 is capable of shifting the hairs constituting the hair bundle 100 in the left-right direction X by moving the second friction plate section 102 relative to the first friction plate section 101 in the left-right direction X while the hair bundle 100 is sandwiched between the first friction plate section 101 and the second friction plate section 102.

[0036] As shown in FIG. 1, the first friction plate portion 101 has a main support surface 103 which is the upper surface, and is a portion that supports the hair bundle 100 from below by the main support surface 103. The second friction plate portion 102 has a main pressing surface 105 as its lower surface, and is a pressing portion that presses the hair bundle 100 toward the first friction plate portion 101 by means of the main pressing surface 105.

[0037] (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.

[0038] Next, the positional relationship between the components of the brushing device 1 according to the first embodiment of the present invention will be described.

[0039] 3, the brushing device 1 has a first brushing part 10 and a second brushing part 11 that face each other in the front-to-back direction Y with the holding part 3 and the mixing part 5 sandwiched between them, and the first brushing part 10 and the second brushing part 11 are arranged in a V-shape. That is, the first brushing part 10 and the second brushing part 11 are spaced apart in the front-to-back direction Y from the top end to the bottom end. The mixing section 5 is disposed between the holding section 3 and the first brushing section 10 and / or between the holding section 3 and the second brushing section 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.

[0040] Next, an example of a method for brushing the hair bundle 100 using the brushing device 1 of the first embodiment of the present invention will be described.

[0041] The brushing operation of the brushing device 1 of this embodiment is mainly composed of a positioning 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.

[0042] (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.

[0043] 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 4(a), and on the lower side, each support plate section 50 moves from the lower side to the upper side in the inclined direction.

[0044] (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. 4(b), and the held portion 110 of the hair bundle 100 is sandwiched between the first roll 80 and the second roll 81.

[0045] 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.

[0046] (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. 5, 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.

[0047] At this time, in each brushing part 10, 11, as shown in Figure 5, 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 holding unit 3 in the position adjustment process described above or the moving process described later, or by the friction plate units 101, 102 in the mixing process described later, and therefore does not move in the longitudinal direction (the direction of travel of the chain units 32a, 32b). 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.

[0048] 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.

[0049] (Mixing process) The mixing step is a step carried out in the second combing operation, and is mainly a step carried out before the second or subsequent combing steps. The mixing process is a process of spreading the hair bundle 100 in the left-right direction X to mix the hairs, and is a process of preventing the convex portion 61 from passing through gaps between hairs that the convex portion 61 has passed through in the past in the subsequent combing process. In the mixing step, 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 some freedom of movement. Next, as shown in Fig. 6(a), the hair bundle 100 is sandwiched in a planar manner between the main support surface 103 of the first friction plate portion 101 and the main pressing surface 105 of the second friction plate portion 102, and in this state, the first friction plate portion 101 and the second friction plate portion 102 are moved in different directions in the left-right direction X, as shown in Fig. 6(b), to spread the hair bundle 100 in the left-right direction X.

[0050] At this time, the movement of the first friction plate part 101 and the second friction plate part 102 generates a shearing force on the hair bundle 100, causing it to shift in the left-right direction X. Therefore, the position of the hair in the hair bundle 100 can be moved without the worker having to manually move the hair bundle 100.

[0051] (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. 7(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. 7(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).

[0052] According to the brushing device 1 of the present embodiment, brushing can be performed by moving the convex portion 61 with the moving means 15, so brushing can be performed without relying on 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 1 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.

[0053] According to the brushing device 1 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.

[0054] According to the brushing device 1 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.

[0055] According to the brushing device 1 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.

[0056] According to the brushing device 1 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 1 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.

[0057] According to the brushing device 1 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.

[0058] According to the brushing device 1 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 1 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.

[0059] According to the brushing device 1 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.

[0060] According to the brushing device 1 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.

[0061] According to the brushing device 1 of this embodiment, in the brushing operation, a shear force is generated in the hair bundle 100 in the width direction, and the hair of the hair bundle 100 is moved in the width direction (left-right direction X) by the mixer 5, which serves as a shear force generating means for moving the hair of the hair bundle 100 in the width direction, and the support part 16 is moved by the moving means 15. Therefore, it is possible to prevent the convex part 61 from passing only at the same position on the hair bundle 100 in the width direction.

[0062] According to the brushing device 1 of this embodiment, the mixer 5 sandwiches the hair bundle 100 between the first friction plate portion 101 and the second friction plate portion 102, and generates shearing force by moving the first friction plate portion 101 and the second friction plate portion 102 relatively in the width direction. Therefore, the hairs of the hair bundle 100 can be easily moved in the width direction.

[0063] According to the brushing device 1 of this embodiment, in the brushing operation, the mixing unit 5 moves the hair of the hair bundle 100 in the width direction, and the holding unit 3 holds the held portion 110. Therefore, in the combing process, the hair bundle 100 can be prevented from returning to the position before the shearing force was applied.
