Description

Brushing device and method for manufacturing artificial hair bundle

[0001] The present invention relates to a brushing device and a method for manufacturing an artificial hair bundle.

[0002] Conventionally, natural hair has been reproduced by bundling hair of the same length and brushing the bundle to shift the ends of the hair (see, 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.

[0003] Patent No. 4756689

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

[0005] Therefore, the present invention aims to provide a brushing device that is less susceptible to individual differences in quality due to differences in operator skill compared to conventional devices, and a method for manufacturing artificial hair bundles that can reproduce natural hair ends.

[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, the brushing device comprising: a first support part that has a plurality of first protrusions and that inserts the plurality of first protrusions into gaps between the hairs that make up the hair bundle, and supports one end side of the hair bundle in a planar manner while the hair bundle is spread out in the width direction; and a first moving means that moves the first support part in the longitudinal direction of the hair bundle so that the first protrusions move from the center side of the hair bundle beyond the one end.

[0007] According to this aspect, the hair bundle can be brushed by moving the first protrusions, so brushing can be done regardless of the operator's skill. Therefore, compared to conventional methods, individual differences in quality due to differences in operator skill are less likely to occur. According to this aspect, the hair bundle is supported in a planar shape by the first support portion, so the hair bundle is appropriately distributed on the first support portion, making it easier for the first protrusions to pass through the gaps between the hairs in the hair bundle, allowing for smooth brushing.

[0008] In a preferred aspect, the first support portion has a support body portion inclined with a vertical component and a horizontal component, and the first protrusion portion standing upright relative to the support body portion.

[0009] In a preferred aspect, the first support portion has the plurality of first protrusions distributed at intervals in a planar manner.

[0010] In a preferred aspect, the first support portion has a group of widthwise convex portions in which the first convex portions are arranged at intervals in the width direction of the hair bundle, and the hairs that make up the hair bundle are passed between the first convex portions of the group of widthwise convex portions.

[0011] In a preferred aspect, the hair straightening device has a plurality of second protrusions, inserts the plurality of second protrusions into gaps between the hairs that make up the hair bundle, has a second support portion that supports the other end side of the hair bundle in a planar manner, and is equipped with a second moving means that moves the second support portion in the longitudinal direction of the hair bundle so that the second protrusions move from the center side of the hair bundle beyond the other end side of the hair.

[0012] In a preferred aspect, the first moving means moves the first support part horizontally in a direction away from the second support part while the hair bundle is strung across the first support part and the second support part.

[0013] In a preferred aspect, the hair straightening device has a holding portion that holds a held portion that belongs to the middle part of the hair bundle, and the holding portion is capable of feeding the held portion to a position where it overlaps with the first convex portion.

[0014] In a preferred aspect, the holding portion has a first roll and a second roll, and is capable of holding the held portion of the hair bundle by sandwiching it between the first roll and the second roll, and the holding portion rotates the first roll and / or the second roll to send the held portion to a position where it overlaps with the first support portion.

[0015] In a preferred aspect, the hair curler includes a lifting portion that lifts a part of the hair bundle so that a tip of the first protrusion passes through gaps between the hairs of the hair bundle.

[0016] A preferred aspect is a brushing unit having the first support part and the first moving means, wherein the brushing part has a rotation axis on the central side of the hair bundle and is capable of changing its position between a first position and a second position by rotating around the rotation axis, wherein in the first position, the first support part can be moved so that the first convex part moves from the central side of the hair bundle to pass over one of the ends of the hair, thereby brushing one of the ends of the hair bundle, and in the second position, the first support part can be moved so that the first convex part moves from the central side of the hair bundle to pass over the other end of the hair, thereby brushing the other end of the hair bundle.

[0017] One aspect of the present invention is a method for producing an artificial hair bundle, which includes the steps of shifting the ends of a hair bundle using the brushing device described above, and tying the hair bundle with the shifted ends.

[0018] According to this aspect, it is possible to produce an artificial hair bundle that replicates natural hair.

[0019] 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.

[0020] The brushing device of the present invention is less susceptible to individual variations in quality due to differences in the skill of the operator than conventional brushing devices. The method for producing a hair bundle of the present invention makes it possible to produce a hair bundle that reproduces the look of natural hair.

[0022] Hereinafter, embodiments of the present invention will be described in detail.

[0023] 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 multiple hairs and shift the position of the hair ends. The brushing device 1 can be suitably used in the production of artificial hair bundles, and can be used when brushing the hair bundle 100, which is an in-process artificial hair bundle. The artificial hair bundle is made by shifting the position of the hair ends of the hair bundle 100 and binding them with a binding member.

[0024] As shown in FIGS. 1 to 3, the brushing device 1 includes a main body 2, a holding portion 3, a stand 4, and a mixing portion 5.

[0025] (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.

[0026] The brushing parts 10, 11 are parts that comb the hair bundle 100, and are inclined with a horizontal component and a vertical component from the end on the holding part 3 side to the opposite end. That is, the first brushing part 10 is inclined downward from the rear end (the end on the holding part 3 side) to the front end in the front-to-rear direction Y, and the second brushing part 11 is inclined downward from the front end (the end on the holding part 3 side) to the rear end in the front-to-rear direction Y.

[0027] When viewed from the side, the brushing units 10 and 11 have an inclination angle θ1 (the angle of the straight line connecting the centers of the gear units 30a and 31a (30b and 31b)) with respect to the horizontal plane shown in FIG. 3 that exceeds 0 degrees, and is preferably 15 degrees or greater, more preferably 30 degrees or greater, and even more preferably 45 degrees or greater. The inclination angle θ1 of the brushing units 10 and 11 shown in FIG. 3 is less than 90 degrees, and is preferably 80 degrees or less, and more preferably 75 degrees or less. The inclination angles θ1 of the brushing units 10 and 11 may be the same angle or different angles. In the following description, the direction of the straight line connecting the centers of the gear units 30a and 31a (30b and 31b) is referred to as the inclination direction.

[0028] As shown in FIGS. 1 to 3, the brushing units 10 and 11 each include a moving means 15 (first moving means, second moving means) and a support unit 16 .

[0029] The moving means 15 is a part that moves the support part 16 in one direction, and is specifically a chain conveyor. As shown in Figures 1 and 3, the moving means 15 includes upper gear parts 30a and 30b, lower gear parts 31a and 31b, chain parts 32a and 32b, a connecting shaft part 33, and a power source 35.

[0030] The gear portions 30a, 30b, 31a, 31b are rotational force transmission portions, specifically sprockets, that engage with portions 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 (the holding portion 3 side) at a distance from the lower gear portions 31a, 31b in the front-rear direction Y, and are provided above the lower gear portions 31a, 31b in the up-down direction Z.

[0031] The chain portion 32a (32b) is a portion that endlessly suspends between the gear portions 30a and 31a (30b and 31b), and is specifically a roller chain.

[0032] The connecting shaft portion 33 is a portion that connects the central axes of the upper gear portions 30a, 30b and synchronizes them.

[0033] The power source 35 is a geared motor having a rotatable shaft, and the shaft is connected to the lower gear portion 31 a, so that the lower gear portion 31 a can be rotated. That is, by driving the power source 35, the moving means 15 can rotate the lower gear portion 31 a, rotate the upper gear portion 30 a via the chain portion 32 a in conjunction with the rotation of the lower gear portion 31 a, rotate the upper gear portion 30 b synchronously via the connecting shaft portion 33 in conjunction with the rotation of the upper gear portion 30 b, and rotate the lower gear portion 31 b via the chain portion 32 b in conjunction with the rotation of the upper gear portion 30 b.

[0034] As the gear parts 30a, 30b, 31a, and 31b rotate, the chain parts 32a and 32b synchronize with each other and rotate in a surrounding manner. That is, as the gear parts 30a, 30b, 31a, and 31b rotate, the upper parts of the chain parts 32a and 32b move in a direction away from the holding part 3 (the direction in which the chain parts 32a and 32b move) and the lower parts of the chain parts 32a and 32b move in a direction toward the holding part 3, with the gear parts 30a, 30b, 31a, and 31b as references.

[0035] As shown in FIG. 3 , the support portion 16 includes a support body portion 21 , a plurality of pin holder portions 22 , and a lifting portion 23 .

[0036] The support main body 21 is a part that supports the hair bundle 100 from below in a planar manner, and is composed of a plurality of support plate parts 50 arranged side by side as shown in Figure 2. The support main body 21 has the support plate parts 50 arranged at intervals in the extension direction of the chain parts 32a, 32b, and the support plate parts 50 are located on the same plane above the chain parts 32a, 32b. In other words, the support main body 21 has a support surface formed by the support plate parts 50 above the chain parts 32a, 32b that supports the hair bundle 100 from below.

[0037] 2, the support plate portion 50 is a plate-like body extending in the left-right direction X so as to connect 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.

[0038] 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. As shown in Fig. 3, the base 60 is a plate-like portion that is placed on the support plate 50 and fixed to the support plate 50. The projections 61 are projections that project perpendicular to the base 60 and have pointed tips. As shown in Fig. 2(b), the projections 61 are distributed in a planar manner on the base 60. The height of the projections 61 is preferably 30 mm or more and 300 mm or less.

[0039] As shown in FIG. 2B , the pin stand 22 has a plurality of widthwise projection groups 62a, 62b, which are arranged parallel to each other at intervals in the width direction (inclination direction). In this embodiment, the widthwise projection groups 62a, 62b are configured with a plurality of projections 61 spaced apart in the left-right direction X. In this embodiment, the plurality of projections 61 are arranged at equal intervals in the left-right direction X. As shown in FIG. 2B , each projection 61 constituting the widthwise projection group 62a is offset in the left-right direction X from each projection 61 constituting the adjacent widthwise projection group 62b in the inclination direction. In the width direction of the pin stand 22, the projections 61 of the widthwise projection group 62a are positioned between adjacent projections 61 of the widthwise projection group 62b.

[0040] The lifting portion 23 is a portion that lifts a portion of the hair bundle 100 so that the convex portion 61 of the pin frog portion 22 can pass through 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 portion 71 is a portion that presses the hair bundle 100 and forms a space between the hair bundle 100 and the pin frog portion 22, and is a protruding piece that protrudes in an arc shape from the base portion 60 as shown in Figure 1. It is preferable that the height of the lifting portion 23 (the height from the support plate portion 50 to the top of the pressing piece portion 71) is equal to or greater than the height of the pin frog portion 22 (the height from the support plate portion 50 to the tip of the convex portion 61).

[0041] (Holding unit 3) The holding unit 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 also serves as a transport unit that transports the hair bundle 100 in the front-to-rear direction Y. The holding unit 3 has a first roll 80 and a second roll 81, as shown in Figure 3 .

[0042] The first roll 80 is a feed roll that feeds the hair bundle 100 in the front-to-rear direction Y. The rotation speed of the first roll 80 is adjustable, and it can rotate forward to feed the hair bundle 100 toward the first brushing unit 10, and rotate backward to feed the hair bundle 100 toward the second brushing unit 11.

[0043] 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 clamping roll that clamps the hair bundle 100 together with the first roll 80 and is a nip roll that 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 as shown in Figure 4(b) and a separated state in which it is separated from the first roll 80 as shown in Figure 4(a). The holding unit 3 clamps the hair bundle 100 by bringing the second roll 81 into a close 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.

[0044] (Frame 4) The frame 4 is a support frame that supports the holding unit 3, and includes a base 90 and support columns 91 a, 91 b as shown in Fig. 1. The support columns 91 a, 91 b are erected on the base 90 and are capable of supporting the rolls 80, 81 of the holding unit 3.

[0045] (Mixing unit 5) The mixing unit 5 is a part 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 the hair bundle 100 by shifting it in the left-right direction X. As shown in Fig. 1 , the mixing unit 5 includes a first friction plate portion 101 and a second friction plate portion 102, and the friction plate portions 101, 102 are arranged to face each other in the up-down direction Z. As shown in Fig. 6 , the mixing unit 5 sandwiches the hair bundle 100 between the first friction plate portion 101 and the second friction plate portion 102, and moves the second friction plate portion 102 in the left-right direction X relative to the first friction plate portion 101, thereby being able to shift the hairs that make up the hair bundle 100 in the left-right direction X.

[0046] 1, the first friction plate portion 101 has a main support surface 103 as its 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 the main pressing surface 105.

[0047] (Hair bundle 100) 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 the same length or different lengths as long as they have a certain length. The shortest hair among the hairs constituting the hair bundle 100 preferably has a length of 100 mm or more and 3000 mm or less. The hairs constituting the hair bundle 100 may be crimped. The hair bundle 100 of this embodiment is an artificial hair bundle in progress, and is a bundle of artificial hair before brushing.

[0048] Next, the positional relationship between the components of the brushing device 1 according to the first embodiment of the present invention will be described.

[0049] 3 , the brushing device 1 has a first brushing unit 10 and a second brushing unit 11 that face each other in the front-to-rear direction Y with the holding unit 3 and the mixing unit 5 sandwiched therebetween, 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-rear direction Y from the top to the bottom. The mixing unit 5 is arranged between the holding unit 3 and the first brushing unit 10 and / or between the holding unit 3 and the second brushing unit 11. The support unit 16 has a lifting unit 23 and each pin holder 22 fixed onto the support plate 50 of the support body 21, and the lifting unit 23 and each pin holder 22 are arranged in this order in the direction of travel of the chains 32 a and 32 b. In the support portion 16, the lifting portion 23 and each pin holder portion 22 are arranged at intervals in the direction of travel of the chain portions 32a and 32b.

[0050] Next, an example of a method for producing an artificial hair bundle by brushing the hair bundle 100 with the brushing device 1 of the first embodiment of the present invention will be described.

[0051] The method for manufacturing an artificial hair bundle of this embodiment includes a brushing step in which the hair bundle 100 is brushed using the brushing device 1, and a tying step in which the middle portion of the hair bundle 100 whose ends have shifted due to brushing is tied up with a tying member. The brushing device 1 of this embodiment performs a brushing operation in the brushing step. The brushing operation of the brushing device 1 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 a first combing operation in which the position adjustment step, the holding step, and the combing step are performed in this order, and further involves alternately performing one or more times, after the first combing operation, a second combing operation in which the mixing step, the combing step, and the holding step are performed in this order, and a third combing operation in which the moving step, the holding step, and the combing step are performed in this order. After the first combing operation, the second or third combing operation may be performed. The number of times of the second combing operation and the third combing operation is not particularly limited, but is preferably 2 to 10 times.

[0052] (Position Adjustment Process) The position adjustment process is a process that is mainly performed before the holding process, and is a process of adjusting the position of each of the pin holders 22 and lifting parts 23 of each brushing unit 10, 11, and positioning the hair bundle 100 so that it straddles the support parts 16 of each brushing unit 10, 11, as shown in Figure 4. Specifically, the position adjustment process is a process of adjusting the support surface on the upper side of each brushing unit 10, 11 so that it is composed of multiple support plates 50, and the worker positions the hair bundle 100 so that it straddles the support surface of the brushing unit 10, 11. In the position adjustment process, the power source 35 is driven to move the chain parts 32a, 32b so that the pin holders 22 are positioned lower in each brushing unit 10, 11. Note that if the pin holders 22 are originally positioned lower in each brushing unit 10, 11, it is not necessary to move the chain parts 32a, 32b.

[0053] At this time, the rotation of the lower gear portion 31a by the power source 35 rotates the chain portion 32a, and the rotation of the chain portion 32a rotates the upper gear portion 30a. The rotation of the upper gear portion 30a also rotates the upper gear portion 30b via the connecting shaft portion 33, and the rotation of the upper gear portion 30b rotates the chain portion 32b, which in turn rotates the lower gear portion 31b. In this manner, in each brushing unit 10, 11, the chain portions 32a, 32b run synchronously with the rotation of the lower gear portion 31a by the power source 35, so that the upper support plate portions 50 move from the upper side to the lower side in the inclined direction, as shown by the arrows in FIG. 4( a ), and the lower support plate portions 50 move from the lower side to the upper side in the inclined direction.

[0054] (Holding Process) The holding process is a process carried out before the combing process, 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 process, as shown by the arrow in Figure 4(b), the second roll 81 is moved from a separated state to a close state, and the held portion 110 of the hair bundle 100 is sandwiched between the first roll 80 and the second roll 81.

[0055] 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.

[0056] (Combing Process) The combing process is a process that is mainly performed after the holding process described above or the mixing process described later, and is a process of brushing the hair bundle 100 and shifting the ends of the hair bundle 100. In the combing process, as shown in Fig. 5 , with the held portion 110 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 (held portion 110 side) of the hair bundle 100 to the front end. 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 (held portion 110 side) of the hair bundle 100 to the rear end.

[0057] At this time, in each brushing unit 10, 11, as shown in Figure 5, the lifting unit 23, which precedes the pin holder unit 22 in the movement direction of the support plate unit 50 (the movement direction of the chain units 32a, 32b), scoops up the hair bundle 100 upward, and causes the convex parts 61 of the pin holder unit 22 to enter the gap between the hair bundle 100 and the support surface, passing through the gaps between the hairs of the hair bundle 100. As a result, the hair bundle 100 is positioned above the convex parts 61, and the tips of the convex parts 61 pierce the hair bundle 100, so the convex parts 61 pass through the gaps between the hairs of the hair bundle 100 smoothly without tangling the hair, and the convex parts 61 divide the hair bundle 100 into multiple sections. Furthermore, at this time, the hair bundle 100 is clamped and restricted by the rolls 80, 81 or friction plate portions 101, 102 of the holding unit 3 in the position adjustment step described above or the movement step described below, and therefore does not move in the longitudinal direction (the direction in which the chain portions 32a, 32b move). In the combing step of this embodiment, the power sources 35 of the brushing units 10, 11 are driven simultaneously, so that the gear portions 30a, 30b, 31a, 31b rotate at the same speed, and the respective chain portions 32a, 32b move in the direction in which they move. Therefore, both end sides of the hair bundle 100 are brushed simultaneously with the same force.

[0058] In the combing process, the number of times the leading pin holder 22 is passed over the hair bundle 100, i.e., the number of rotations of each brushing part 10, 11, is not particularly limited, but is preferably between 2 and 10 times.

[0059] (Mixing Process) The mixing process is a process performed in the second combing operation, and is mainly performed before the second or subsequent combing processes. 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 portions 61 from passing through gaps between hairs that the convex portions 61 have passed through in the past in subsequent combing processes. In the mixing process, the second roll 81 is moved from a close state to a separated state, and the second roll 81 is moved upward from the held portion 110, allowing the hair bundle 100 to have some freedom of movement. Next, as shown in Figure 6(a), the hair bundle 100 is clamped 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, as shown in Figure 6(b), the first friction plate portion 101 and the second friction plate portion 102 are moved in different directions in the left-right direction X to spread the hair bundle 100 in the left-right direction X.

[0060] At this time, the movement of the first friction plate portion 101 and the second friction plate portion 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.

[0061] (Moving Process) The moving process is a process performed in the third combing operation, and is mainly performed before the second or subsequent combing processes. The moving process is a process in which the held portion 110, which is clamped between the rolls 80, 81 of the holding unit 3, is moved in the front-to-back direction Y, and moved onto the support surface of the first brushing unit 10 or the second brushing unit 11. In the moving process, 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 separated upward 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 unit 10 (or the second brushing unit 11).

[0062] According to the brushing device 1 of this embodiment, brushing can be performed by moving the convex parts 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 1 of this embodiment, the hair bundle 100 is supported in a planar manner by the support part 16, so the hair bundle 100 is appropriately distributed on the support part 16, making it easier for the convex parts 61 to pass through gaps between the hairs in the hair bundle 100, allowing for smooth brushing.

[0063] 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 convex 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 convex part 61 can easily pass through gaps between the hairs in the hair bundle 100.

[0064] 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, so that the protrusions 61 can pass through the hair bundle 100 evenly.

[0065] 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.

[0066] 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. This allows the brushing units 10 and 11 to brush both ends of the hair bundle 100. This reduces brushing time compared to conventional brushes. According to the brushing device 1 of this embodiment, the brushing unit 10 supports one end 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 end of the hair bundle 100 in a planar manner using the support unit 16 (second support unit). Therefore, at the end of each hair, the hair is dispersed appropriately on the support parts 16, 16, and the convex parts 61, 61 can easily pass through the gaps between the hairs in the hair bundle 100.

[0067] 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. This allows the ends of each hair of the hair bundle 100 to be brushed separately or simultaneously.

[0068] According to the brushing device 1 of this embodiment, the holding part 3, which holds the held part 110 belonging to the middle part of the hair bundle 100, can feed 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 part 10, 11, so the hair bundle 100 can be brushed in stages. For example, it is possible to brush the hair in separate areas, such as the ends, middle, and end.

[0069] 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. This makes it easy to brush the held portion 110.

[0070] 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.

[0071] According to the brushing device 1 of this embodiment, during the brushing operation, 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 that generates a shear force in the hair bundle 100 and moves the hair of the hair bundle 100 in the width direction, and the support part 16 is moved by the moving means 15. This prevents the convex part 61 from passing only at the same position on the hair bundle 100 in the width direction.

[0072] 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 hair of the hair bundle 100 can be easily moved in the width direction.

[0073] According to the brushing device 1 of this embodiment, during 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, during the combing process, the hair bundle 100 can be prevented from returning to the position before the shear force was applied.

[0074] According to the brushing device 1 of this embodiment, the lifting part 23 lifts the hair bundle 100 upward, and the tip of the convex part 61 passes through the gaps between the hairs in the hair bundle 100. Therefore, the hair bundle 100 is positioned above the convex part 61, and the tip of the convex part 61 penetrates the hair bundle 100, so the convex part 61 can easily pass through the gaps between the hairs in the hair bundle 100 smoothly without tangling the hair.

[0075] The method for manufacturing an artificial hair bundle using the brushing device 1 of this embodiment includes a step of shifting the ends of the hair bundle 100 and a step of bundling the hair bundle 100 with the shifted ends using the brushing device 1. Therefore, an artificial hair bundle that reproduces natural hair can be manufactured.

[0076] Next, a brushing device 201 according to a second embodiment of the present invention will be described. Note that the same components as those in the brushing device 1 according to the first embodiment will be denoted by the same reference numerals and will not be described again. The same applies hereinafter.

[0077] As shown in Figure 8, the brushing device 201 of the second embodiment of the present invention comprises a main body 2, a holding portion 3, a stand portion 4, and a mixing portion 205, and the mixing portion 205 is different from the mixing portion 5 of the first embodiment.

[0078] (Mixing unit 205) The mixing unit 205 is a part that mixes the hair bundle 100 by shifting it in the left-right direction X, and is a dividing means that divides the hair bundle 100 into multiple bundles in the width direction. As shown in Figure 8, the mixing unit 205 is equipped with a first dividing unit 211 and a second dividing unit 212, and by sandwiching the hair bundle 100 between the first dividing unit 211 and the second dividing unit 212, it is possible to shift the hair bundle 100 in the left-right direction X. That is, the mixing unit 205 has a dividing movement means that moves the first dividing unit 211 and the second dividing unit 212, and is movable between a close position where the first dividing unit 211 is relatively close to the second dividing unit 212 and a separated position where the first dividing unit 211 is relatively separated from the second dividing unit 212. The mixing section 205 is capable of sandwiching the hair bundle 100 between the first dividing section 211 and the second dividing section 212 when they are in the close position.

[0079] As shown in FIG. 9 , the first divided portion 211 has a first base portion 220 and a plurality of first pressing portions 221. The first base portion 220 is a plate-shaped portion that has a width in the front-rear direction Y and extends in the left-right direction X. The first pressing portions 221 are convex portions that protrude upward from the first base portion 220, and are plate-shaped convex ridge portions that have a width in the left-right direction X, a thickness in the up-down direction Z, and extend in the front-rear direction Y. In the first divided portion 211, the first pressing portions 221 are arranged at intervals in the left-right direction X, and in this embodiment, are arranged at equal intervals. In the first divided portion 211, the height (thickness) of each first pressing portion 221 from the first base portion 220 is the same.

[0080] From another perspective, the first dividing portion 211 has a plurality of first recesses 222. Each of the first recesses 222 is a recessed groove having the first base portion 220 as its bottom and the adjacent first pressing portions 221, 221 as its inner walls, and has a depth that increases downward. That is, in the first dividing portion 211, each of the first pressing portions 221 functions as a partition that separates the first recesses 222.

[0081] The second divided portion 212 is paired with the first divided portion 211 and includes a second base portion 230 and a plurality of second pressing portions 231. The second base portion 230 is a plate-shaped portion that has a width in the front-rear direction Y and extends in the left-right direction X. The second pressing portions 231 are convex portions that protrude downward from the second base portion 230 and are plate-shaped convex ridge portions that have a width in the left-right direction X, a thickness in the up-down direction Z, and extend in the front-rear direction Y. In the second divided portion 212, the second pressing portions 231 are arranged at intervals in the left-right direction X, and are arranged at equal intervals in this embodiment. In the second divided portion 212, the height (thickness) of each second pressing portion 231 from the second base portion 230 is the same.

[0082] From another perspective, the second dividing portion 212 has a plurality of second recesses 232. The second recesses 232 are grooves with the second base portion 230 as their bottom and the adjacent second pressing portions 231, 231 as their inner walls, and have a depth that increases upward. That is, in the second dividing portion 212, each second pressing portion 231 functions as a partition that separates the second recesses 232.

[0083] Here, focusing on the positional relationship of each part of the first divided portion 211 and the second divided portion 212, the first pressing portion 221 of the first divided portion 211 is arranged at a position corresponding to the second recess 232 of the second divided portion 212 in the up-down direction Z, and the first recess 222 is arranged at a position corresponding to the second pressing portion 231 of the second divided portion 212 in the up-down direction Z. In this embodiment, the first pressing portion 221 of the first divided portion 211 is located between the second pressing portions 231, 231 adjacent to each other in the left-right direction X, and the second pressing portion 231 of the second divided portion 212 is located between the first pressing portions 221, 221 adjacent to each other in the left-right direction X.

[0084] Next, the brushing operation of the brushing device 201 according to the second embodiment of the present invention will be described.

[0085] The brushing operation of the brushing device 201 of this embodiment is mainly composed of a position adjustment process, a holding process, a combing process, a mixing process, and a moving process, and only the mixing process differs from the brushing operation of the brushing device 1 of the first embodiment.

[0086] (Mixing Process) In the mixing process, 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 Figure 10, the first dividing portion 211 and the second dividing portion 212 are brought close to each other to clamp the hair bundle 100, and the second pressing portions 231 of the second dividing portion 212 press the hair bundle 100 into the first recesses 222 of the first dividing portion 211. This causes the hair bundle 100 to be partitioned by the first recesses 222, and the hair spreads and mixes in each first recess 222 in the left-right direction X, causing the hair bundle 100 as a whole to spread in the left-right direction X. If necessary, the second dividing section 212 is moved in the width direction (left-right direction X) relative to the first dividing section 211 by the dividing moving means, so that the end of the first pressing section 221 abuts the end of the second pressing section 231, and each strand of hair bundle 100 divided by the first pressing section 221 is separated by the first pressing section 221 and the second pressing section 231.

[0087] According to the brushing device 201 of this embodiment, in the brushing operation, the hair bundle 100 is divided into a plurality of bundles by the dividing units 211, 212, and the support unit 16 having the convex portions 61 is moved by the moving means 15. Therefore, it is possible to prevent the convex portions 61 from passing only at the same position on the hair bundle 100 in the width direction.

[0088] According to the brushing device 201 of this embodiment, since it has width direction moving means that can move each of the dividing sections 211, 212 of the mixing section 205 in the width direction, it is possible to adjust the position of the hair bundle 100 in the left-right direction X.

[0089] According to the brushing device 201 of this embodiment, the mixing unit 205 divides the hair bundle 100 into a plurality of bundles by being housed in the first recess 222 of the dividing unit 211. Therefore, the hair bundle 100 can be easily moved in the width direction.

[0090] According to the brushing device 201 of this embodiment, the mixing unit 205 presses the hair bundle 100 toward the recess 222 of the dividing unit 211 using the plurality of second pressing units 231 of the dividing unit 212, thereby storing the hair of the hair bundle 100 in the recess 222. Therefore, even if the hair of the hair bundle 100 is crimped or the like and is therefore prone to tangling, the hair can be stored in the recess 222 of the dividing unit 211.

[0091] According to the brushing device 201 of this embodiment, in the brushing operation, the mixing unit 205 divides the hair bundle 100 into multiple bundles, and the holding unit 3 holds the held portion 110 of the hair bundle 100. Therefore, in the combing process, the hair bundle 100 can be prevented from returning to the position before being divided by the mixing unit 205.

[0092] Next, a brushing device 301 according to a third embodiment of the present invention will be described.

[0093] As shown in Figure 11, the brushing device 301 of the third embodiment of the present invention comprises a main body portion 2, a holding portion 3, a stand portion 4, and a mixing portion 305, and the mixing portion 305 is different from the mixing portion 5 of the first embodiment.

[0094] (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 as shown in Fig. 11 , it includes a first uneven section 311 and a second uneven section 312. 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 is capable of clamping the hair bundle 100 between the first uneven section 311 and the second uneven section 312 in the close position.

[0095] As shown in FIG. 12 , the first uneven portion 311 has a first base portion 320 and a first partition portion 321. The first base portion 320 is a plate-shaped 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 streak portion that has a width in the left-right direction X, a thickness in the up-down direction Z, and extends in the front-rear direction Y. The first uneven portion 311 has multiple widths for the first partition portion 321, and in this embodiment, the widths of the first partition portions 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 different intervals between the first partitions 321, 321 adjacent to each other in the left-right direction X, and in this embodiment, the intervals between the first partitions 321, 321 adjacent to each other in the left-right direction X are different from each other.

[0096] From another perspective, the first uneven portion 311 has a plurality of first recesses 322. The first recesses 322 are grooves with the first base portion 320 as their bottom and the adjacent first partition portions 321, 321 as their inner walls, and have a depth that increases downward. The first uneven 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 all different. In the first uneven portion 311, all of the first recesses 322 have the same depth.

[0097] The second uneven portion 312 is a clamping portion that forms a pair 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 multiple second partitions 331. The second base portion 330 is a plate-shaped portion that has a width in the front-rear direction Y and extends in the left-right direction X. The second partitions 331 are convex portions that protrude downward from the second base portion 330 and are plate-shaped convex ridge portions that have a width in the left-right direction X, a thickness in the up-down direction Z, and extend in the front-rear direction Y. The second uneven portion 312 has multiple widths for the second partitions 331, and in this embodiment, the widths of the respective second partitions 331 are different. In the second uneven portion 312, the height (thickness) of the second partitions 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. In the second uneven portion 312, there are a plurality of types of intervals between the second partition portions 331, 331 adjacent to each other in the left-right direction X, and in this embodiment, the intervals between the second partition portions 331, 331 adjacent to each other in the left-right direction X are different from each other.

[0098] From another perspective, the second uneven portion 312 has a plurality of second recesses 332. The second recesses 332 are grooves with the first base portion 320 as their bottom and the adjacent second partition portions 331, 331 as their inner walls, and have a depth that increases upward. The second uneven portion 312 has 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 all different. In the second uneven portion 312, all of the second recesses 332 have the same depth.

[0099] 12( b), when the second uneven portion 312 is in a position where the mixing section 305 is in a proximity position where the second uneven portion 312 is relatively close to the first uneven portion 311, the first uneven portion 311 has at least one first partition portion 321 that overlaps with the second partition portion 331 of the second uneven portion 312 in the vertical direction Z. In addition, the first uneven portion 311 has at least one first recess 322 that overlaps with the second recess 332 in the vertical direction Z. That is, when the second uneven portion 312 is in a proximity position where it is relatively close to the first uneven portion 311, 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.

[0100] 12(b), when the mixing section 305 is in the close position, 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 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 position, at least one continuous enclosed space 342 (recessed 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, as shown in FIG. 12(b), a plurality of enclosed spaces 340-342 are formed surrounding the hair bundle 100.

[0101] Next, the brushing operation of the brushing device 301 according to the third embodiment of the present invention will be described.

[0102] The brushing operation of the brushing device 301 of this embodiment is mainly composed of a position adjustment process, a holding process, a combing process, a mixing process, and a moving process, and only the mixing process differs from the brushing operation of the brushing device 1 of the first embodiment.

[0103] (Mixing Process) In the mixing process, 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. Next, as shown in Figure 13, 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 parts of the hair bundle 100 are enclosed by surrounding spaces 340-342 formed by the first partition portion 321 and / or the first recessed portion 322 of the first uneven portion 311 and the second partition portion 331 and / or the second recessed portion 332 of the second uneven portion 312. Then, 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, the hair spreads and mixes in the left-right direction X, and the hair bundle 100 as a whole spreads in the left-right direction X.

[0104] 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. During the brushing operation, the mixing section 305 clamps the hair bundle 100 and stores the hair bundle 100 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.

[0105] 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 concave enclosed spaces 340-342 that include at least a concave portion 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 concave enclosed spaces 340-342.

[0106] 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.

[0107] According to the brushing device 301 of this embodiment, in the brushing operation, the mixing unit 305 divides the hair bundle 100 into a plurality of enclosed spaces 340 to 342, 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 being surrounded by the mixing unit 305.

[0108] Next, a brushing device 401 according to a fourth embodiment of the present invention will be described.

[0109] As shown in Figure 14, the brushing device 401 of the fourth embodiment of the present invention comprises a main body portion 2, a holding portion 3, a stand portion 4, and a mixing portion 405, and the mixing portion 405 is different from the mixing portion 5 of the first embodiment.

[0110] (Mixing unit 405) The mixing unit 405 is a folding mechanism that folds and mixes the hair bundle 100 in the left-right direction X, and includes a first plate-shaped portion 411 and a second plate-shaped portion 412, as shown in Fig. 14. An end edge of the second plate-shaped portion 412 in the left-right direction X is connected to an end edge of the first plate-shaped portion 411 in the left-right direction X via a connecting portion such as a hinge (not shown), and the second plate-shaped portion 412 is rotatable relative to the first plate-shaped portion 411. The mixing unit 405 is capable of shifting the hair bundle 100 in the left-right direction X by folding the second plate-shaped portion 412 relative to the first plate-shaped portion 411. That is, the mixing section 405 is capable of changing its position between a planar position in which the mounting surface 415 of the first plate-shaped section 411 and the mounting surface 416 of the second plate-shaped section 412 form the same plane, and a folded position in which the second plate-shaped section 412 rotates and folds relative to the first plate-shaped section 411, and the mounting surface 415 of the first plate-shaped section 411 and the mounting surface 416 of the second plate-shaped section 412 face each other.

[0111] Next, the brushing operation of the brushing device 401 according to the fourth embodiment of the present invention will be described.

[0112] The brushing operation of the brushing device 401 of this embodiment is mainly composed of a position adjustment process, a holding process, a combing process, a mixing process, and a moving process, and only the mixing process differs from the brushing operation of the brushing device 1 of the first embodiment.

[0113] (Mixing Process) In the mixing process, 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 Figure 15, the mixing portion 405 is changed from a flat position to a folded position, and the hair bundle 100 is sandwiched and folded between the mounting surface 415 of the first plate-shaped portion 411 and the mounting surface 416 of the second plate-shaped portion 412. Then, the mixing portion 405 is changed from the folded position to a flat position.

[0114] At this time, the hair bundle 100 is folded from a state in which it straddles the placing surface 415 of the first plate-shaped portion 411 and the placing surface 416 of the second plate-shaped portion 412, and the hair placed on the placing surface 415 of the first plate-shaped portion 411 and the hair placed on the placing surface 416 of the second plate-shaped portion 412 overlap in the thickness direction. As a result, the hair bundle 100 moves in the left-right direction X, and the hairs mix.

[0115] According to the brushing device 401 of this embodiment, the mixing unit 405 can move the hair bundle 100 in the width direction by rotating the first plate-shaped unit 411 relatively to the second plate-shaped unit 412 around the connecting unit, and in the brushing operation, the mixing unit 405 moves the hair bundle 100 in the width direction, and the moving means 15 moves the support unit 16. This prevents the convex portion 61 from passing only at the same position on the hair bundle 100 in the width direction.

[0116] According to the brushing device 401 of this embodiment, in the brushing operation, the hair bundle 100 is moved in the width direction by the mixing part 405, and the held part 110 is held by the holding part 3. Therefore, in the combing process, the hair bundle 100 can be prevented from returning to the position before being folded by the mixing part 405.

[0117] Next, a brushing device 501 according to a fifth embodiment of the present invention will be described.

[0118] 16 , a brushing device 501 according to the fifth embodiment of the present invention includes a main body 502, a holding unit 3, a stand 4, and a mixing unit 5, with the main body 502 differing from the main body 2 of the first embodiment. That is, the main body 502 differs from the main body 2 of the first embodiment in that it includes one brushing unit 510. The brushing unit 510 includes a moving means 15 and a support unit 16, and its position can be changed by rotating the moving means 15 around the upper gears 30 a and 30 b (rotation axis). That is, as shown in Fig. 17, the brushing unit 510 rotates about the upper gear portions 30a, 30b and can change its position between a forward tilt position (first position) in which the brushing unit 510 is tilted downward to the front in the front-to-back direction Y from the upper gear portions 30a, 30b toward the lower gear portions 31a, 31b, as shown by solid lines in Fig. 17, and a rearward tilt position (second position) in which the brushing unit 510 is tilted downward to the rear in the front-to-back direction Y from the upper gear portions 30a, 30b toward the lower gear portions 31a, 31b, as shown by imaginary lines in Fig. 17.

In the forward tilt position, the power source 35 rotates the lower gear 31a in the forward direction to move the support unit 16 from the center of the hair bundle 100 past one of the hair ends, and in the backward tilt position, the power source 35 rotates the lower gear 31a in the reverse direction to move the support unit 16 from the center of the hair bundle 100 past the other of the hair ends. This allows the brushing unit 501 to have both the functions of the brushing unit 10 and the brushing unit 11 of the first embodiment.
