Description
本発明は、筆の穂の形状を成形する製穂用具に関するものである。 The present invention relates to a spike making tool for shaping the shape of a brush ear.
特許文献１に示すような筆作りにおける各工程では、作業者の長年の経験や勘が必要であることが多いが、製造コストを低廉にするためには、経験が少ない作業者であっても治具や機械を使って一定の品質でしかも製造時間を短縮できるようにすることが大きな課題である。 Each process in brush making as shown in Patent Document 1 often requires many years of experience and intuition of the operator, but in order to reduce the manufacturing cost, even an inexperienced operator It is a big problem to be able to reduce the manufacturing time with a certain quality using jigs and machines.
ここで、図８に示すような製穂用具１００が開発され、筆の穂の形状を成形する製穂工程では熟練者でなくても一定の品質とし得るようになっている。 Here, a spike making tool 100 as shown in FIG. 8 has been developed, and even in the spike making process for shaping the shape of the brush ear, it is possible to obtain a certain quality even if it is not an expert.
図８に記載の製穂用具１００は、縦断面略Ｕ字状で横断面円形の成形部１２を有する製穂用具１００である。この成形部１２の形状は設計された筆の穂の形状になっている。 The spike making tool 100 shown in FIG. 8 is a spike making tool 100 having a molding part 12 having a substantially U-shaped vertical section and a circular cross section. The shape of the molded part 12 is the shape of a brush ear designed.
この製穂用具１００によると、この成形部１２に上方から筆毛Ｆの束を挿入して筆毛Ｆの自重によって縦断面略Ｕ字状の成形部１２に筆毛Ｆを沿わせることで、穂の形状を成形することができる。
よって、経験が豊富ではない作業者が製穂工程を行っても、穂の形状を一定の品質とすることが可能である。
According to this spike making tool 100, by inserting a bundle of brushes F from above into the molding part 12 and causing the brushes F to follow the molding part 12 having a substantially U-shaped longitudinal section by the weight of the brush F, The shape of the ear can be formed.
Therefore, even if an operator with little experience performs the spike making process, the shape of the spike can be made to have a certain quality.
しかしながら、この製穂用具１００を用いて製穂工程を行うときには、筆の穂の形状を確認しながら作業を行うことができないという問題がある。
つまり、筆毛Ｆが自重で落下して設計通りの穂の形状となったかどうかは、筆毛Ｆがバラバラにならないように筆毛Ｆの束をワイヤーで括った後に製穂用具１００から取り出さないと確認することができない。
However, when performing the spike making process using the spike making tool 100, there is a problem that the operation cannot be performed while checking the shape of the brush ear.
In other words, whether or not the brush F has fallen by its own weight and has become the shape of the ear as designed is not taken out from the spike making tool 100 after the bundle of the brush F is wrapped with a wire so that the brush F does not fall apart. Can not be confirmed.
仮に筆毛Ｆが落ち切っておらず製穂用具１００から取り出して確認した結果、穂の外形が凸凹であった場合には、ワイヤーを切って再び製穂作業を行わなければならないので、非常に時間の無駄が多くなってしまう。 As a result of taking out and confirming that the brush F has not fallen off from the panning tool 100, and the outer shape of the pan is uneven, it is necessary to cut the wire and perform the panning operation again. A lot of time is wasted.
他方、製穂用具１００に筆毛Ｆをセットした上で製穂用具１００に微小振動を加えて強制的に筆毛Ｆを落下させて成形部１２に沿わせる手法も知られているが、ワイヤーで括って筆毛Ｆの束を製穂用具１００から取り出さなければ穂の形状を確認できないということには変わりがない。 On the other hand, there is also known a technique in which the brush F is set on the spike making tool 100 and then the brush F is forcibly dropped by the brush making tool 100 so that the brush F is forced to fall along the molding part 12. In other words, the shape of the ears cannot be confirmed unless the bundle of brushes F is taken out from the ear making tool 100.
そこで、本発明の目的とするところは、熟練者でなくても短時間でより正確に穂の形状を成形することができる製穂用具を提供することにある。 Accordingly, an object of the present invention is to provide a spike making tool that can form the shape of a spike more accurately in a short time even if it is not an expert.

ここで、上記括弧内の記号は、図面および後述する発明を実施するための形態に掲載された対応要素または対応事項を示す。 Here, the symbols in the parentheses indicate corresponding elements or corresponding matters described in the drawings and the embodiments for carrying out the invention described later.
本発明によれば、基部の上面から上方へ突出する駒を備えるので、上方から筆毛を製穂用具に挿入して筆毛の根元部分を成形部に沿わせることで、穂先（毛先）を見ながら製穂作業を行うことができる。 According to the present invention, since the piece that protrudes upward from the upper surface of the base portion is provided, the brush tip is inserted into the spike making tool from above and the root portion of the brush is aligned with the forming portion, so that the tip (tip) It is possible to carry out spike making while watching
つまり、製穂用具から筆毛を取出すことなく、穂を目視しながらその形状を整えることができるので、熟練者でなくても正確に穂の形状を成形することが可能である。また、筆毛の落下（整列）が不十分な状態で筆毛の束をワイヤーで括ってしまうことを防げるので、結果的に短時間で穂を成形できる。 That is, the shape of the ear can be accurately formed even if it is not an expert because the shape of the ear can be adjusted while visually checking the ear without taking out the brush from the ear making tool. Further, it is possible to prevent the bundle of brushes from being bundled with wires in a state where the fall (alignment) of the brushes is insufficient, and as a result, ears can be formed in a short time.
また、本発明によれば、成形部の周面に、外方から内方に向かって略水平又は下方に傾斜する複数の支持面を備えるので、筆毛が支持面に載ることで筆毛が成形部に沿って滑り落ちて外方に移動してしまうことを抑制可能である。特に、成形部における外側の部分の傾きは大きいので、何ら対策を施さないと筆毛が成形部から滑り落ちて外側に偏ってしまい、穂が設計したものよりも先細りになりがちであるが、支持面によってこの外側の部分の筆毛の外方への移動を抑制できる。 Further, according to the present invention, the peripheral surface of the molded part is provided with a plurality of support surfaces that are inclined substantially horizontally or downwardly from the outside to the inside, so that the brush is placed on the support surface so that the brush is placed on the support surface. It is possible to suppress sliding down along the molding part and moving outward. In particular, the slope of the outer part of the molded part is large, so if you do not take any measures, the brush will slide off the molded part and bias to the outside, tending to taper than what the ears designed, The support surface can suppress the outward movement of the brush at the outer portion.
また、本発明によれば、複数の支持面は、それぞれ環状に一周するように形成されたので、駒の製造が容易で製造コストも低廉となる。 Further, according to the present invention, since the plurality of support surfaces are formed so as to make one round, each piece is easy to manufacture and the manufacturing cost is low.
また、支持面を螺旋状に繋げて形成することもできる。 It can also be formed by connecting the support surfaces in a spiral.
なお、本発明の製穂用具のように、基部の上面から上方へ突出する成形部を有する駒を備える点は、上述した特許文献１には全く記載されていない。 In addition, the point provided with the piece which has a shaping | molding part which protrudes upwards from the upper surface of a base like the spike making tool of this invention is not described in patent document 1 mentioned above at all.
図１乃至図６を参照して、本発明の実施形態に係る製穂用具２００を説明する。
この製穂用具２００は、駒２０と、筒体３０と、を備え、筆（特に化粧筆）の穂の形状を成形するものである。
A spike making tool 200 according to an embodiment of the present invention will be described with reference to FIGS.
This ear-making tool 200 includes a piece 20 and a cylindrical body 30, and shapes the shape of the ear of a brush (especially a makeup brush).
駒２０は、基部２１と成形部２２からなる。
基部２１は円盤状で、駒２０とは別体である。
成形部２２は、基部２１の上面から上方へ突出するとともに下方から上方に向かって縮径し、正面視略逆Ｕ字状である。また、平面視では図２に示すように円状であって、成形部２２は軸対称である。
The piece 20 includes a base portion 21 and a molding portion 22.
The base 21 has a disc shape and is separate from the piece 20.
The molded part 22 protrudes upward from the upper surface of the base part 21 and has a reduced diameter from the lower part to the upper part, and has a substantially inverted U shape when viewed from the front. Moreover, in plan view, as shown in FIG. 2, it is circular and the molding part 22 is axisymmetric.
そして、成形部２２の周面には支持面２２ａが複数形成されている。この複数の支持面２２ａはそれぞれが水平面であって、平面視で環状に一周するように成形部２２の周面（外殻）に形成される。
このとき、成形部２２が下方から上方に向かって縮径しているので、上方の支持面２２ａほど直径は小さくなっており、各支持面２２ａは階段状となっている。また、同じ直径の支持面２２ａは当然ながら存在しない。
A plurality of support surfaces 22 a are formed on the peripheral surface of the molding portion 22. Each of the plurality of support surfaces 22a is a horizontal surface, and is formed on the peripheral surface (outer shell) of the molding portion 22 so as to make one round in a plan view.
At this time, since the molding part 22 is reduced in diameter from the lower side to the upper side, the diameter of the upper support surface 22a is smaller, and each support surface 22a is stepped. Of course, there is no support surface 22a having the same diameter.
支持面２２ａの幅（径方向の幅）は一本の筆毛Ｆの根元部分の径より広い必要があるが、この筆毛Ｆの径以上であれば筆の穂の外形を滑らかな曲線状とするためには極力狭いほうがよい。
なお、支持面２２ａの径方向の幅は狭いので、図１の斜視図は概略図とし、成形部２２の各支持面２２ａ間の段差の記載は省略している。また、段差数も図２や図３に比べて少なく記載している。また、図４は図３の一部を拡大したものである。
The width of the support surface 22a (the width in the radial direction) needs to be wider than the diameter of the root portion of one brush F. If the diameter of the brush F is larger than the diameter of the brush F, the outer shape of the brush ear is smoothly curved. It is better to be as narrow as possible.
Since the radial width of the support surface 22a is narrow, the perspective view of FIG. 1 is a schematic diagram, and the step between the support surfaces 22a of the molding portion 22 is not shown. Further, the number of steps is also reduced as compared with FIG. 2 and FIG. FIG. 4 is an enlarged view of a part of FIG.
筒体３０は、図１及び図５に示すように、成形部２２を囲う略円筒状であって、筒体３０の内径は駒２０の成形部２２の最大径と略等しく、筒体３０の外径は駒２０の基部２１の外径と略等しい。 As shown in FIGS. 1 and 5, the cylindrical body 30 has a substantially cylindrical shape surrounding the molding portion 22, and the inner diameter of the cylindrical body 30 is substantially equal to the maximum diameter of the molding portion 22 of the piece 20. The outer diameter is substantially equal to the outer diameter of the base 21 of the piece 20.
そして、筒体３０が成形部２２を囲ったとき、筒体３０の下面が駒２０の基部２１の上面に当接する。
また、筒体３０の高さは駒２０の成形部２２の高さよりも高い。
これらの駒２０と筒体３０の材質は特段限定されない。
When the cylindrical body 30 surrounds the molding portion 22, the lower surface of the cylindrical body 30 comes into contact with the upper surface of the base portion 21 of the piece 20.
Further, the height of the cylindrical body 30 is higher than the height of the molding portion 22 of the piece 20.
The material of these pieces 20 and the cylindrical body 30 is not particularly limited.
このような製穂用具２００を用いて行う製穂工程について説明する。
まず、駒２０に対して筒体３０を被せて筒体３０によって駒２０の成形部２２を囲う。
そして、筒体３０の上方開口へ長さを揃えた筆毛Ｆの束を挿入する。
The spike making process performed using such a spike making tool 200 will be described.
First, the cylindrical body 30 is covered with the piece 20, and the molding part 22 of the piece 20 is surrounded by the cylindrical body 30.
Then, a bundle of brushes F having the same length is inserted into the upper opening of the cylindrical body 30.
次に、微小振動可能な作業台によって筆毛Ｆの束が入った製穂用具２００に微小振動を加える。微小振動を加えている間、作業者は筆毛Ｆが製穂用具２００内で落下して整列したか否かを目視により確認する。
最後に、図６に示すように筆毛Ｆが整列し穂が設計された形状となったら、筆毛Ｆの筒体３０から露出した部分の下部をワイヤーで括って筆毛Ｆがバラバラにならないようにする。
Next, a minute vibration is applied to the spike making tool 200 containing a bundle of brushes F by a workbench capable of minute vibration. While applying the minute vibration, the operator visually checks whether or not the brush F has fallen and aligned in the spike making tool 200.
Finally, as shown in FIG. 6, when the brush F is aligned and the shape of the ear is designed, the lower part of the portion exposed from the tubular body 30 of the brush F is tied with a wire so that the brush F does not fall apart. Like that.
以上のように構成された製穂用具２００によれば、基部２１の上面から上方へ突出する駒２０を備えるので、上方から筆毛Ｆを製穂用具２００に挿入して筆毛Ｆの根元部分を成形部２２に沿わせることで、穂先（毛先）を見ながら製穂作業を行うことができる。
つまり、製穂用具２００から筆毛Ｆを取出すことなく、穂を目視しながらその形状を整えることができるので、熟練者でなくても正確に穂の形状を成形することが可能である。また、筆毛Ｆの落下（整列）が不十分な状態で筆毛Ｆの束をワイヤーで括ってしまうことを防げるで、結果的に短時間で穂を成形できる。
According to the spike making tool 200 configured as described above, since the piece 20 protrudes upward from the upper surface of the base portion 21, the brush F is inserted into the spike making tool 200 from above and the root portion of the brush F is inserted. By aligning with the forming part 22, it is possible to perform the spike making operation while looking at the tip (hair tip).
That is, since the shape of the ear can be adjusted while visually observing the ear without taking out the bristle F from the ear making tool 200, the shape of the ear can be accurately formed even if it is not an expert. Moreover, it is possible to prevent the bundle of the brushes F from being bundled with the wire in a state where the fall (alignment) of the brushes F is insufficient, and as a result, the ears can be formed in a short time.
また、成形部２２の周面に、水平の複数の支持面２２ａを備えるので、筆毛Ｆが支持面２２ａに載ることで筆毛Ｆが成形部２２に沿って滑り落ちて外方に移動してしまうことを抑制可能である。特に、成形部２２における外側の部分の傾きは大きいので、何ら対策を施さないと筆毛Ｆが成形部２２から滑り落ちて外側に偏ってしまい、設計したものよりも穂が先細りになりがちであるが、支持面２２ａによってこの外側の部分の筆毛Ｆの外方への移動を抑制できる。 Moreover, since the peripheral surface of the shaping | molding part 22 is equipped with several horizontal support surfaces 22a, the brush F slides down along the shaping | molding part 22 and moves outward by the brush F being mounted on the support surface 22a. Can be suppressed. In particular, since the inclination of the outer portion of the molded portion 22 is large, the brush F tends to slide off the molded portion 22 and be biased to the outside unless any countermeasure is taken, and the ears tend to taper more than the designed one. However, the support surface 22a can suppress the outward movement of the brush F at the outer portion.
さらに、複数の支持面２２ａは、それぞれ環状に一周するように形成されたので、駒２０の製造が容易で製造コストも低廉となる。 Furthermore, since each of the plurality of support surfaces 22a is formed so as to make a circle, the piece 20 can be easily manufactured and the manufacturing cost can be reduced.
なお、本実施形態において、成形部２２や筒体３０の内側を平面視で円形としたが、これに限られるものではなく、設計された他の形状としてもよい。例えば、図７に示すように成形部２２をハート型に上方へ突出する形状とすることができる。このときの筒体３０の内側も同様にハート型とする必要がある。なお、図７においては基部２１の記載を省略した。 In addition, in this embodiment, although the inside of the shaping | molding part 22 and the cylinder 30 was circular by planar view, it is not restricted to this, It is good also as another designed shape. For example, as shown in FIG. 7, the molding part 22 can be shaped to protrude upward in a heart shape. The inside of the cylinder 30 at this time also needs to be a heart shape. In addition, description of the base 21 was abbreviate | omitted in FIG.
また、成形部２２の支持面２２ａは水平であるとしたが、これに限られるものではなく、製穂用具２００に微小振動を加えた際に筆毛Ｆが外方へ滑り落ちないのであれば傾いていてもよい。例えば、支持面２２ａを外方から内方に向かって下方に傾斜させていてもよい。 Moreover, although the support surface 22a of the shaping | molding part 22 was assumed to be horizontal, it is not restricted to this, If the brush F does not slide out outward when a minute vibration is applied to the earing tool 200, It may be tilted. For example, the support surface 22a may be inclined downward from the outside toward the inside.
また、支持面２２ａを環状に一周するように形成したが、螺旋状に繋がっていてもよい。さらにこれらに限られるものではなく、それぞれの筆毛Ｆが載るスペースがあれば、支持面２２ａはどのように形成されていてもよい。穂の外形が滑らかな曲線状となるためには、各支持面２２ａの面積は狭いほうがよい。 Further, although the support surface 22a is formed so as to make one round, the support surface 22a may be spirally connected. Furthermore, it is not restricted to these, If the space which each brush F mounts exists, the support surface 22a may be formed how. In order for the outer shape of the spike to have a smooth curved shape, the area of each support surface 22a should be narrow.
加えて、駒２０と筒体３０は別体であるとしたが、これに限られるものではなく一体であってもよい。
また、駒２０の基部２１は円盤状であるとしたが、形状は限定されるものではない。
In addition, although the piece 20 and the cylindrical body 30 are separate bodies, they are not limited to this and may be integrated.
Moreover, although the base 21 of the piece 20 is disc-shaped, the shape is not limited.
