[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a brush and a flocking device thereofAnd flocking methodIn particular, a brush in which a hair bundle is planted using a small piece of metal called a flat wire and its deviceAnd flocking methodAbout.
[0002]
[Prior art]
For example, taking a toothbrush as an example, a conventionally used flat-wire type toothbrush flocking device, as shown in FIG. 13 and FIG. 14, implants a long hair bundle 81 in which a predetermined number of monofilaments such as nylon are bundled. A hair bundle supply mechanism 84 that intermittently feeds a fixed length when the hair transplantation needle 83 of the mechanism 82 is raised, and a pressing portion 85 that is disposed on the upper front side of the hair bundle supply mechanism 84 and presses the hair bundle on the lower surface thereof. An auxiliary guide body 88 provided with a needle hole 86 opened vertically through the pressing portion 85 and a flat wire insertion hole 87 penetrating the needle hole, and slides up and down along the needle hole 86 of the auxiliary guide body 88. The moving flocking needle 83 and the auxiliary guide body 88 are positioned below the auxiliary guide body 88 so as to be movable up and down, and the needle guide hole 90 provided so as to coincide with the extension line of the needle hole 86 is opened and opened. The hair receiving portion 91 of the hair bundle 81 is recessed A flocking guide 92 that holds and holds the hair bundle 81 between the pressing portion 85 when ascending, and is located between the hair bundle supply mechanism 84 and the flocking guide 92 so as to be disposed close to the hair bundle 81, and the flocking guide. From a hair bundle cutting mechanism 94 having a rotary cutter 93 that cuts the hair bundle 81 into a predetermined length when the hair 92 is raised, and a flat wire supply mechanism 96 that feeds a flat wire 95 into the flat wire insertion hole 87 of the auxiliary guide body 88. (See Japanese Patent Publication No. 49-27382).
[0003]
And the conventional hair transplantation apparatus which becomes the said structure transplants the hair | bristle bundle 81 on the hair transplantation surface 3 of the head part 2 of the toothbrush handle 1 as follows. That is, first, as shown in FIG. 13, the long bundle of hairs 81 is fed into the hair receiving portion 91 by the hair bundle supply mechanism 84 until it hits the stopper 97, and at the same time, as shown in FIG. Accordingly, the thin flat wire 95 is fed into the flat wire insertion hole 87 of the auxiliary guide body 88.
[0004]
Next, the hair bundle 81 fed into the hair receiving portion 91 is held and clamped by the pressing portion 85 at the tip of the auxiliary guide body 88, and in this state, the hair bundle 81 is made a fixed size by the rotary cutter 93 of the hair bundle cutting mechanism 94. After the cutting, the entire hair-implanting mechanism 82 and the auxiliary guide body 88 are lowered toward the toothbrush handle 1.
[0005]
Further, simultaneously with the descent of the flocking mechanism 82 and the auxiliary guide body 88, the flocking needle 83 is driven downward along the needle hole 86 and the needle guide hole 90. As a result, the flat wire 95 is cut to a predetermined length at the tip of the flocking needle 83, the cut flat wire 95 is pushed out as it is, and the hair bundle cut into a fixed size by the flat wire 95. 81 is pushed into the needle guide hole 90 while being folded into a U-shape at the center and folded in half.
[0006]
When the tip of the flocking mechanism 82 comes closest to the flocking surface 3 of the head portion 2 of the toothbrush handle 1, the tip of the flocking needle 83 pops out of the needle guide hole 90, and the hair bundle 81 cut to a fixed size is removed. In the state folded in half by the flat wire 95 of the small piece, it is driven into the flocking hole 4 of the flocking surface 3, and flocked as shown in FIGS. 15 (a) and 15 (b).
[0007]
By repeating the above operation for each flocking hole 4, the bristles 81 folded in half by the flat wire 95 are sequentially implanted in the flocking holes 4 of the flocking surface 3 of the head portion 2 of the toothbrush handle 1. Is.
[0008]
[Problems to be solved by the invention]
However, in the case of the conventional flocking device described above, as shown in FIG. 16, the driving angle θ of the flat line 95 with respect to the flocking hole 4 is always constant (for example, θ = 12 ° fixed). The driving angle could not be changed freely. For this reason, when the space | interval of the adjacent flock holes 4 is made too narrow, there is a possibility that the driven flat wires 95 may collide with each other, cracks due to the driving of the flat wires 95, or weakening due to resin whitening. There was a problem that it was difficult to realize high-density flocking because the spacing of the line had to be larger than a certain amount.
[0009]
Further, since the driving angle θ of the flat line is fixed, the arrangement pattern of the hair bundle to be implanted is limited to an arrangement pattern in which adjacent flat lines do not interfere with each other, such as a linear arrangement or a lattice arrangement. Such an arrangement pattern, for example, a circle-like flocking in which hair bundles are arranged in a circle or a curved flocking arranged along an arbitrary curve could not be realized. For this reason, in the case of a conventional flat-line type toothbrush, a toothbrush with brush arrangements in various directions corresponding to the brushing position and brushing method in the oral cavity, such as a toothbrush made by an in-mold method or a heat fusion method It was difficult to provide.
[0010]
Further, although not shown in FIG. 13 and FIG. 14, normally, as shown in FIG. 17, hair splitting is performed on the tip side portion of the hair transplant guide 92 for driving a flat wire in synchronization with the hair transplantation operation of the hair transplant guide 92. A hair separation device 99 that reciprocally swings the plate 98 is installed, and when the hair bundle is driven into the next flock hole 4, the next hair bundle 81 that has already been flocked is pressed down from the advancing and retreating path of the flocking guide 92. By letting it escape, the adjacent hair bundle 81 that has already been implanted is caught to prevent generation of the connecting hair 81a as shown in FIG. 18 (a) and the ring hair 81b as shown in FIG. 18 (b). Yes.
[0011]
However, in the case of the conventional hair transplantation device, the hair separation device 99 is fixed at a fixed position with respect to the hair transplantation mechanism 82, and the toothbrush handle simply moves in parallel. In order to prevent the generation of the ring hair 81b, the already bundled hair bundles must always be carried out in order from a specific side that is easily separated by the hair dividing device, and the arrangement pattern of the hair bundles is also regulated by this hair arrangement order. There was a problem that. In an actual production line, due to the arrangement pattern of the hair bundle, there is a case where it is unavoidable to plant the hair from the side far from the hair separation device 99. In such a case, the connecting hair 81a and the ring hair are used. The risk of generating 81b was unavoidable, and this was one cause of defective products.
[0012]
The present invention has been made to solve the above problems, and provides a flat-line brush that enables high-density flocking and flocking in an arbitrary arrangement pattern by changing the driving angle of the flat line depending on the location. It is for the purpose.
[0013]
Furthermore, the present invention can freely change the implantation angle of the flat line with respect to the flocked hole, can realize high density flocking, and can implant flocks of any arrangement pattern such as circle flocking and curved flocking, which has been difficult in the past. A flocking device that can be realized in any driving order and does not cause the occurrence of connected or ring hairsAnd flocking methodIs intended to provide.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, the brush according to the present invention is a brush in which a hair bundle is formed on a flocked hole formed on a flocked surface of a brush head portion, and the hair bundle is folded in two with a flat wire interposed therebetween. The angle is different between at least two or more flat lines in FIG.
[0015]
In addition, it is desirable that the flock hole is divided into a plurality of holes and each has a flat wire. In this case, the partition which isolate | separates between the at least 2 flock holes adjacent is made into the thickness of the range of 0.1-3.0 mm. Furthermore, it is desirable to set the driving angle of each flat wire so that the extension line along the longitudinal direction of each flat wire does not reach the adjacent flock hole.
[0016]
In the case of a brush having such a configuration, it can be arranged so that adjacent flat lines do not collide with each other by changing the angle of the flat line. High-density flocking is possible, and in the past, it was realized only by the in-mold method or heat fusion method, such as circle-shaped flocking in which hair bundles are arranged in a circle or curved flocking arranged along an arbitrary curve. A free flocking pattern that could not be achieved can also be realized.
[0017]
In addition, the hair transplantation device according to the present invention includes a hair transplanting means for planting hair bundles on the hair transplantation surface of the brush head part using a flat wire, and is arranged to face the hair transplantation means at a predetermined distance, and the brush head part. A brush holding base capable of holding the brush holding base in a fixed position, a position adjusting means capable of freely adjusting the position of the brush holding base with respect to the flocking means, and a rotation inclination angle of the brush holding base with respect to the flocking means. A brush rotation mechanism that can be adjusted, and by moving and controlling the position adjusting means, the position of the brush holding base with respect to the flocking means can be freely changed, and the flocking means can be controlled by rotating the brush rotation mechanism. The rotation inclination angle of the brush holding base with respect to is freely changed.
Furthermore, the hair transplantation method according to the present invention is a brush planting method in which a hair bundle is folded in two on the hair transplantation surface of the brush head unit using a flat line, and the brush head unit of the brush to be planted is used. After being held at a fixed position of the brush holding base, the brush holding base is arranged opposite to the flat-wire-type flocking means, the position adjusting means freely changes the position of the brush holding base with respect to the flocking means, and the brush rotation mechanism is used for flocking The hair bundle is sequentially implanted on the flocked surface of the brush head portion held on the brush holding table while freely changing the rotation inclination angle of the brush holding table with respect to the means.
[0018]
Flocking device with such a configurationAnd flocking methodIn this case, the driving angle of the flat wire with respect to the flocked hole can be freely changed for each flocked hole. For this reason, high-density flocking can be realized, and it is possible to realize flocking having an arbitrary arrangement pattern such as circle-shaped flocking and curved flocking, which has been difficult in the past.
[0019]
Also, by rotating the brush handle 360 degrees freely, it is possible to always maintain the positional relationship between the already bundled hair bundle and the next planted hole to be implanted as shown in FIG. . For this reason, it is possible to perform flocking from any position of the flocking hole, and there is no possibility that the flocking order is regulated by the arrangement pattern of the hair bundle as in the conventional case, and the next hair bundle is involved. It is possible to eliminate the possibility of generation of connecting hairs and ring hairs. Furthermore, by enabling 360-degree rotation, ring-shaped flocking as shown in FIGS. 6 (a), 6 (b), 7 and 8 can be made possible.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show an embodiment of a flat-wire type toothbrush flocking device constructed by applying the present invention. FIG. 1 is an electrical circuit diagram of the embodiment, FIG. 2 is a schematic front view showing an external structure of the embodiment, and FIG. 3 is a schematic cross-sectional view taken along line AA in FIG. In addition, the same code | symbol was attached | subjected and shown to the same or equivalent mechanism part as the conventional flat wire-type toothbrush flocking apparatus (FIG. 13, FIG. 14) mentioned above. Also, the hair separation device 99 (FIG. 17) is not shown.
[0021]
As shown in the figure, the hair transplantation device according to the embodiment is roughly divided into a hair-planting mechanism for embroidering a hair bundle that is folded in half with a flat wire using a flocking needle in the same manner as a conventional flat-line toothbrush flocking device ( A hair transplanting means) 82, an XYZ table 11 which is arranged to face the hair transplanting mechanism 82 and moves in the XYZ triaxial directions so that the position thereof can be adjusted, and the XYZ table 11 is rotatably arranged on the XYZ table 11. The brush rotation mechanism 12 is provided.
[0022]
The flocking mechanism 82 has the same structure as the above-described conventional flat-line toothbrush flocking device (FIGS. 13 and 14). During flocking, the flocking mechanism 82 advances and retreats along the center line OO of the needle guide hole. A hair bundle 81 folded in half by a wire is driven out by a flocking needle, and is implanted into the flocked hole 4 of the flocked surface 3 of the head portion 2 of the toothbrush handle 1 held by the handle holding portion 16 described later.
[0023]
The XYZ table 11 is composed of a combination of an X-axis table 11a that moves in the left-right direction, a Y-axis table 11b that moves up and down, and a Z-axis table 11c that moves back and forth in the front-rear direction. The servo motors 13a, 13b, and 13c are driven and controlled by the table servo driver 14, so that their positions can be freely adjusted.
[0024]
The brush rotation mechanism 12 includes a brush holder 16 that is rotatable in both forward and reverse directions by a rotation support shaft 15 fixed on the back surface, a rotation servomotor 17, and a rotation for driving and controlling the servomotor 17. The moving servo driver 18 is composed of gears 20 and 21 and a driving belt 22 that connect the rotating support shaft 15 of the brush holder 16 and the rotating shaft 19 of the servo motor 17.
[0025]
The brush holder 16 is a gripping mechanism for inserting the head part 2 of the toothbrush handle 1 to be planted and gripping it at a fixed position. For example, the brush holder 16 has nail parts 23a to 23d formed at its four corners. By inserting the head portion 2 of the toothbrush handle 1 to be held, the entire toothbrush handle 1 can be held in place.
[0026]
The brush rotation mechanism 12 including the brush holding table 16 is fixed to the XYZ table 11 by an attachment member 24. By controlling the movement of the XYZ table 11, the position of the brush holding table 16 in the XYZ direction can be freely set. FIG. 4 shows the direction of the toothbrush handle 1 gripped on the brush holding table 16, that is, the rotation inclination angle θ of the handle, by rotating the brush holding table 16 by the rotating servo motor 17. It can be changed freely. FIG. 4 shows a typical angle setting example, and it is needless to say that an arbitrary angle in the middle of the angle can be set freely.
[0027]
Reference numeral 25 denotes a control unit configured by combining, for example, a personal computer and a PC (sequencer) for controlling the operation of the entire apparatus including the table servo driver 14, the rotation servo driver 18, and the flocking mechanism 82.
[0028]
Next, the operation will be described. First, the toothbrush handle 1 to be implanted is inserted into the nail pieces 23a to 23d of the brush holder 16 so that the implanted surface 3 faces the front side by an automatic loading machine or manually, and the entire toothbrush handle 1 is gripped. Grip on the table 16.
[0029]
When the toothbrush handle 1 is gripped on the handle grip base 16, the control unit 25 controls the table servo driver 14 to drive the X-axis servo motor 13a, the Y-axis servo motor 13b, and the Z-axis servo motor 13c. By doing so, the XYZ of the brush holder 16 is set so that the position of the first flocking hole 4 in the flocking order matches the central axis OO of the needle guide hole 90 (see FIGS. 13 and 14) of the flocking mechanism 82. Adjust the position of the direction.
[0030]
At the same time, the control unit 25 controls the servo driver 18 for rotation and drives the servo motor 17 for rotation so that the toothbrush handle 1 held on the brush holder 16 has a specified inclination angle. Adjust the rotation angle.
[0031]
When the position adjustment of the toothbrush handle 1 in the XYZ directions and the adjustment of the inclination angle are completed, the control unit 25 controls the flocking mechanism 82, and in the same manner as the conventional toothbrush flocking device described above, the bristles 81 are separated by the flat wire 95. Fold it out and plant it in the flocking hole 4 of the flocking surface 3.
[0032]
The above-described flocking operation is repeatedly performed for each flocking hole 4. As a result, as shown in FIG. 5, it is possible to plant the hair while freely changing the driving angle θ of the flat wire 95 for each planting hole 4. As a result, the flat lines 95 of adjacent flocking holes 4 do not get in the way and get in the way, and the hair bundle can be flocked at a high density. FIG. 5 also shows a typical angle setting example, and it is needless to say that an arbitrary angle in the middle can be set freely.
[0033]
Further, by rotating the toothbrush handle 1, it is possible to always set the positional relationship between the hair bundle 81 that has already been implanted and the flocking hole 4 to be implanted next to the relationship shown in FIG. For this reason, it is possible to perform flocking from any position of the flocking hole, and the flocking order is not restricted by the arrangement pattern of the hair bundle as in the prior art. This also eliminates the generation of the connecting hairs 81a and the ring hairs 81b shown in FIGS. 18A and 18B, thereby reducing the occurrence rate of defective products.
[0034]
The example of the arrangement | sequence pattern of the hair | bristle bundle which can be flocked by the said flocking apparatus to Fig.6 (a)-(d) is shown. The arrangement pattern of the illustrated example is that the flock holes 4 having a rectangular shape are arranged adjacent to each other close to each other with a thin wall therebetween, and (a) is a circular arrangement of the flock holes 4 having a rectangular shape. (B) is an example of U-shaped flocking in which rectangular shaped flock holes 4 are arranged in a U-shape, and (c) is an example of Y-shaped flocking in which rectangular flocked holes 4 are arranged in a Y-shape. , (D) shows examples of windmill type flocking in which rectangular flocking holes 4 are arranged in a windmill shape.
[0035]
As is clear from the figure, in any arrangement pattern, since the driving angles of the flat wires 95 driven into the flock holes 4 are different, the adjacent flat wires 95 do not collide with each other. The hair can be implanted in such an arbitrarily arranged pattern. Further, since the flock holes 4 are arranged close to each other across the thin wall, there is no gap between the follicles, and the hair bundle density is extremely high.
[0036]
The example of the toothbrush planted by the said hair transplant apparatus in FIGS. 7-10 is shown.
The arrangement pattern of the hair bundles in these toothbrushes cannot be realized by a conventional flat-wire-type flocking device, and is realized only by a flocking device using an in-mold method or a heat fusion method. However, according to the present invention, even if the arrangement pattern is extremely complicated as shown in the figure, it is possible to plant hair without any difficulty. Furthermore, the shape of the flocking hole 4 is not limited to the conventional round hole, but may be a square or a fan as shown in the figure, or may be any other shape such as a triangle, polygon, star, or compound curve. It is possible to adopt a flocking hole. Therefore, it is possible to provide a flat-line type toothbrush in which brushes are arranged in various directions corresponding to the brushing position and the brushing method in the oral cavity.
[0037]
When manufacturing toothbrushes having various arrangement patterns as illustrated in FIGS. 7 to 10, as shown in FIGS. 11A and 11B, an extension line P− along the longitudinal direction of the flat line 95 is used. It is desirable to set the driving angle of the flat wire 95 so that P does not reach other adjacent flock holes 4. If a flat wire is driven within such an angle range, it is possible to prevent cracks from occurring between adjacent flock holes 4 or whitening of the resin of the head portion when the flat wire is driven. Furthermore, it is desirable that the thickness d of the partition wall separating adjacent flocking holes 4 is in the range of d = 0.1 to 3.0 mm.
[0038]
In each of the above-described examples, each flocked hole 4 is separated by a partition wall to form each flocked hole as an independent hole, and one flat wire is provided for each of the independent flocked holes 4. 95 shows a case where one hair bundle 81 is driven in, but the method of implanting the hair bundle is not limited to this, and for example, as shown in FIGS. 12 (a) and 12 (b) The flocked hole 4 is formed in a long hole shape having a plurality of hole lengths, and a plurality of hair bundles 81 are formed by using a plurality of flat wires 95 in the elongated hole-shaped flocked hole 4.One by oneIt may be stuffed side by side and planted. In the case of this hair transplantation method, there is a possibility that the hair bundle previously planted may fall into the empty space part on the side where the next hair is to be implanted and disturb the planting of the next hair bundle. This can be prevented by sequentially planting the next hair bundle while pressing the hair bundle implanted one before using the hair separating device 99 shown in FIG. 17 toward the opposite side.
[0039]
thisFIG.(A) When a hair bundle is implanted by the method as shown in (b), since adjacent hair bundles are not separated by a partition wall, it is the same as a toothbrush made by an in-mold method or a heat fusion method. In addition, it is possible to form a series of long hair bundles that are completely continuous. For this reason, the design and fashionability are improved, and it becomes possible to make a toothbrush having a novel brush pattern that does not lose its mark on a toothbrush made by an in-mold method or a heat fusion method.
[0040]
In the above-described embodiment, the brush holding table 16 is configured to be rotationally driven by the rotating servo motor 17, the gears 20, 21, and the drive belt 22. However, the brush holding table 16 only needs to be rotatable. Therefore, it goes without saying that the servo motor 17 may be directly connected or another rotating mechanism may be used.
[0041]
Moreover, although it comprised so that the head part 2 of the toothbrush handle 1 might be hold | gripped with the nail | claw piece 23a-23d formed in the four corners of the brush holding stand 16, if it is a mechanism which can hold | grip the head part 2 of the toothbrush handle 1, It may be a gripping mechanism.
[0042]
The XYZ table 11 is also driven by the three servo motors 13a to 13c. However, the present invention is not limited to this. For example, another drive mechanism such as a linear slider may be used instead of the servo motor. It is.
[0043]
In the above embodiment, the handle rotation mechanism 12 to which the brush holding base 16 is attached is rotatably attached to the XYZ table 11, but conversely, the XYZ table 11 to which the brush holding base 16 is fixedly arranged. Can be configured to be attached to the rotation shaft of the rotation mechanism so as to be movable in the XYZ directions.
[0044]
Furthermore, in the said embodiment, although the XYZ table 11 in which the position control of the XYZ triaxial direction was used, when the flocking surface 3 of the toothbrush handle 1 is a flat flocking surface without unevenness, Position control in the Z-axis direction can be eliminated. Therefore, in such a case, instead of the XYZ table 11, an XY table capable of position control only in the XY biaxial directions can be used.
[0045]
As mentioned above, although embodiment of this invention was described, the application object of this invention is not restricted only to the above-mentioned toothbrush, For example, other brushes, such as a hair brush, a makeup brush, a cleaning brush, etc. are used for a flat line. It can be applied to any type of brush. Further, the present invention can be applied even to a brush that does not include a handle (pattern part).
[0046]
【The invention's effect】
According to the brush according to the present invention, since the driving angle of the flat wire is different between at least two or more flat wires in the flocked hole, it is difficult to achieve with the conventional angle-integrated flat wire brush. It is possible to achieve density flocking, and in the past, this can only be achieved by the in-mold method or heat-sealing method, such as circle-shaped flocking in which hair bundles are arranged in a circle or curved flocking arranged along an arbitrary curve. A free flocking pattern that could not be achieved can also be realized, and a flat-line brush with a brush arrangement optimal for the purpose of brushing and the brushing method can be obtained.
[0047]
Moreover, the hair transplantation apparatus of this inventionAnd flocking methodAccording to the above, by controlling the movement of the position adjusting means,PlantingWhile freely changing the position of the brush holding base with respect to the bristle means and controlling the rotation of the brush rotation mechanism, the rotational inclination angle of the brush holding base with respect to the flocking means can be freely changed, and the hair bundle can be Since the flocking hole is planted, the angle of the flat wire to the flocked hole can be changed freely for each flocked hole, realizing high-density flocking, and circle-shaped flocking and curvilinear flocking, which were difficult in the past. Thus, an excellent effect is achieved in that flocking with an arbitrary arrangement pattern can be realized in an arbitrary driving order. In addition, since it is possible to perform flocking from any position of the flock holes regardless of the arrangement pattern of the hair bundle, the arrangement of the hair arrangement is regulated by the arrangement pattern of the hair bundle as in the past. In addition, it is possible to eliminate the generation of connected hairs and ring hairs due to the involvement of the adjacent hair bundle.
