Definitions
- the present invention relates to a coating operation evaluation apparatus and a coating operation evaluation method.
- Suncare cosmetics are known as functional cosmetics specializing in UV protection.
- a numerical index typified by an SPF (Sun Protection Factor) value is used, and a consumer purchases a product displaying a numerical value appropriate for the actual scene to be used.
- SPF Sun Protection Factor
- This SPF value is a value based on “ISO in vivo SPF measurement method” (see, for example, Non-patent Document 1), and is obtained by in vivo measurement using the skin of a human subject.
- a professional engineer (applicator) performs measurement with a prescribed amount of suncare cosmetics applied to the skin using “finger”.
- the reason for using the finger in this measurement is that the consumer mainly uses the finger when actually using suncare cosmetics, and approximates the state of application on the skin.
- the coated surface is finished so as to be coated with a uniform thickness every time, and means that the same measurement result can be obtained no matter which part of the coated surface is measured.
- the actual thickness of the applied sample depends on the ratio of the remaining amount in the blending components. For example, based on the sample application amount (2.00 mg / cm 2 ) defined by the in vivo SPF measurement method, it becomes a micron unit, and it is not easy to apply with a finger so as to finish the application surface uniformly with this thickness.
- the SPF value of a sample is predicted by physical measurement using an application substrate (see, for example, Patent Document 1 and Non-Patent Document 2) that replaces the skin without using the skin of the subject. Proposals have been made by SPF measurement (see, for example, Patent Documents 2 and 3 and Non-Patent Document 3). This method is often used because it can be measured easily and inexpensively in a development stage of sun care cosmetics and the like.

Therefore, in in vitro SPF measurement and in vivo SPF measurement, considerable training for obtaining the above-described coating method for improving the reproducibility is required within the applicator or between the applicators.

- coating with a uniform thickness is required as one of the conditions for improving the reproducibility of the coating state.
- the present inventor for example, measured the application surface applied at a predetermined application pressure with a spectroscopic measurement device, and found that application with a uniform thickness can be obtained by application with a uniform application pressure.
- the application pressure in the application operation is measured, and the application operation is evaluated so as to apply at a uniform application pressure, thereby realizing the application of the uniform thickness described above and improving the reproducibility of the application state.

Abstract
Description
上述したように、塗布状態の再現性を高める条件の1つとして均一な厚みで塗布することが求められている。本発明者により、例えば所定の塗布圧で塗布した塗布面を分光測定装置により多点計測したところ、均一な厚みの塗布は、均一な塗布圧で塗布することにより得られることが分かった。本実施形態により、塗布動作における塗布圧を計測し、均一な塗布圧で塗布するよう塗布動作を評価することで、上述した均一な厚みの塗布を実現し、塗布状態の再現性を向上させる。
図1は、本実施形態に係る塗布動作評価装置の外観図を示している。図1(A)は、塗布動作評価装置全体を示す。また、図1(B)は、塗布対象面上での塗布動作を示す。また、図1(C)は、塗布対象面に配置されたセンサを示す。
次に、上述した塗布動作評価装置10の機能構成について説明する。図2は、本実施形態に係る塗布動作評価装置の機能構成の一例を示している。
上述した塗布動作評価装置10の各構成は、各機能をコンピュータに実行させる塗布動作評価プログラムを生成し、例えば汎用のパーソナルコンピュータやサーバ等にインストールすることにより実行することが可能である。図3は、本実施形態に係る塗布動作評価装置のハードウェア構成の一例を示す図である。
次に、上述した塗布動作評価装置10により実行される塗布動作評価処理手順について説明する。図4は、本実施形態に係る塗布動作評価処理手順を示すフローチャートである。
次に、上述した塗布基板21上で塗布されるサンプル塗布方法(サンプル秤量から塗布までの手順)について説明する。図5は、塗布基板上で塗布されるサンプル塗布方法を説明する図である。なお、図5(A)は、サンプル秤量を示す図であり、図5(B)は、サンプル秤量を行った塗布基板21を固定した図であり、図5(C)は、塗布手順の流れを示す図である。
図6は、押圧力測定におけるセンサキャリブレーションを説明するための図である。算出手段45は、まず起動時のキャリブレーションとして以下の処理を実行する。
ここで、ゼロ値データa0,nを0g時の各センサ出力(nはセンサ番号1,2,3,4に対応し、番号1~4はセンサ22A~22Dに対応する)とし、b100,nを100g時の各センサ出力とする。次に、キャリブレーション用の係数kを求める。係数kは、k=100.0/(B-A)として求めることができる。
図7は、押圧位置推定前のセンサキャリブレーションについて説明する図である。図7(A)に示すように、センサ22A~22D上に設けられた塗布対象面24の矩形領域を16分割し、分割された矩形領域のそれぞれの座標(x、y)を、(x,y)=(0,0)~(4、4)とする。
次に、上述の座標各点においてセンサ22A~22Dのゼロ値補正をした出力値dcal,n(x,y)を合計して、合計出力値Dcal,n(x,y)を、例えば以下の式(5)を用いて取得する。また、合計出力値Dcal,n(x,y)に対するセンサ22A~22Dそれぞれの出力値dcal,n(x,y)の割合(個別出力割合ecal,n(x,y))を、例えば以下の式(6)を用いて取得する。
上述のように、予めセンサキャリブレーションを行う。また、校正した値fcal,n(x,y)を用いて、以下の通り、塗布対象面24の矩形領域(補正対象領域)の座標を設定するために用いられる座標補正量を取得する。
図8は、座標補正量取得処理の流れを示すフローチャートである。図8に示すように、センサ22A~22Dからゼロ値データa0,nを取得すると(S20)、座標地点(図7の例では、25ヶ所)に所定の重り(例えば100g)を載せたときの出力値ccal,n(x,y)を取得して(S21)、各座標地点でゼロ値補正をした出力値dcal,n(x,y)を取得する(S22)。
例えば、座標(0,0)における上辺に係る割合を求める場合には、Ucal(0,0)=fcal,4(0,0)/(fcal,1(0,0)+fcal,4(0,0))を用いる。同様に、座標(0,0)における下辺、左辺、右辺に係る圧力の割合についてもそれぞれ求める。
例えば左辺の場合には、左辺の座標各点(0,1)、(0,2)、(0,3)、(0,4)で得られる各変位量から、左辺の変位量の平均値を取得する(Lcx=average(WXcal(0,y))。同様に、右辺、上辺、下辺の座標各点で得られる各変位量から、右辺、上辺、下辺の各変位量の平均値を取得する。
次に、上述した変位量を取得する際に用いる式(11)について説明する。図9は、変位量を取得するときに用いる式の考え方の一例を説明する図である。
Ucal=fcal,4/(fcal,1+fcal,4)
として表し、下辺に係る圧力の割合を、
Bcal=fcal,3/(fcal,2+fcal,3)
として表すものとする。
Vcal=(fcal,1+fcal,4)/(fcal,1+fcal,2+fcal,3+fcal,4)
とする。上辺と下辺の重さの割合の合計を「1」とすると、下辺の重さの割合は、
1-Vcal=(fcal,2+fcal,3)/(fcal,1+fcal,2+fcal,3+fcal,4)
と表すことが可能である。なお、Vcalは、上述した垂直方向に係る圧力の割合として説明したものと同様の式である。
WX(x)=(Ucal×(fcal,2+fcal,3)+Bcal×(fcal,1+fcal,4))/(fcal,2+fcal,3+fcal,1+fcal,4)
=Ucal×(fcal,2+fcal,3)/(fcal,2+fcal,3+fcal,1+fcal,4)+Bcal×(fcal,1+fcal,4)/(fcal,2+fcal,3+fcal,1+fcal,4)
=(Ucal×(1-Vcal)+Bcal×Vcal)・・・(14)
同様に、押圧位置Aを押したときのWXのy座標は、以下のように示すことができる。
=fcal,1+fcal,4/(fcal,2+fcal,3+fcal,1+fcal,4)
=Vcal
上述したWX(x)とWX(y)とから、WX(x,y)は以下のように表せる。
したがって、上辺、下辺の横方向の加重割合を加味した、押圧位置AのX座標は、Ucal×(1-Vcal)+Bcal×Vcalと表すことが可能である。
Lcal=fcal,2/(fcal,1+fcal,2)
として表し、右辺に係る圧力の割合を、
Rcal=fcal,3/(fcal,3+fcal,4)
と表すものとする。
Hcal=(fcal,1+fcal,2)/(fcal,1+fcal,2+fcal,3+fcal,4)
とする。左辺と右辺の重さの割合の合計を「1」とすると、右辺の重さの割合は、
1-Hcal=(fcal,3+fcal,4)/(fcal,1+fcal,2+fcal,3+fcal,4)
と表すことが可能である。なお、Hcalは、上述した水平方向に係る圧力の割合として説明したものと同様の式である。
=Lcal×(fcal,3+fcal,4)/(fcal,3+fcal,4+fcal,1+fcal,2)+Rcal×(fcal,1+fcal,2)/(fcal,3+fcal,4+fcal,1+fcal,2)
=Lcal×(1-Hcal)+Rcal×Hcal)
同様に、押圧位置Aを押したときの変位量WYのx座標は、以下のように示すことができる。
=fcal,1+fcal,2/(fcal,3+fcal,4+fcal,1+fcal,2)
=Hcal
上述したWY(x)とWY(y)とから、WY(x,y)は以下のように表せる。
したがって、左辺、右辺の縦方向の加重割合を加味した、押圧位置AのY座標は、Lcal×(1-Hcal)+Rcal×Hcalと表すことが可能となる。
Qx=x1+(x4-x1)×fcal,2/(fcal,2+fcal,3)
したがって、WXは以下のように表すことが可能である。
=Px×(1-V)+Qx×V・・・(15)
上述した式(15)は、上述した式(14)と同等の意味を示すため、上述した手法によりWXと求めることも可能である。また、WYの場合についても上述したWXの場合と同様の手法で求めることが可能である。
更に、上述した変位量を取得する際に用いる式(11)を他の方法で説明する。例えば、図9の例で、左辺から点PまでをP(x)とし、左辺から点QまでをQ(x)とし、左辺から押圧位置AまでをX(x)とする。
a(x)×(1-V)=b(x)×V
=(Q(x)-P(x)-a(x))×V
=Q(x)×V-P(x)×V-a(x)×V
a(x)×(1-V)+a(x)×V=Q(x)×V-P(x)×V
a(x)-(a(x)×V)+(a(x)×V)=Q(x)×V-P(x)×V
a(x)=Q(x)×V-P(x)×V
すなわち、X(x)=P(x)+a(x)
=P(x)-P(x)×V+Q(x)×V
=P(x)×(1-V)+Q(x)×V
又は、a(x):V=(a(x)+b(x)):1
a(x)=(a(x)×V)+(b(x)×V)
a(x)-(a(x)×V)=b(x)×V
=(Q(x)-P(x)-a(x))×V
=Q(x)×V-P(x)×V
すなわち、X(x)=P(x)+a(x)
=P(x)-P(x)×V+Q(x)×V
=P(x)×(1-V)+Q(x)×V・・・(16)
となる。
次に、上述した塗布対象面24(すなわち補正対象領域)が、実際にユーザにより押圧されたときの押圧位置推定処理について説明する。図10は、押圧位置推定処理の流れを示すフローチャートである。図10のS31~S36までの処理は、図8のS22~S23、S25~S28までの処理で用いた方法により実行される。
S37の処理で求めた座標Xp、Ypは、例えば塗布対象面24の左辺と下辺の交点(すなわち左下の隅)が原点(基準点)となる。したがって、例えば塗布対象面24の中央を原点とするためには、所定の値(例えば対角線上を100分割した場合には、「50」)を用いて、位置オフセット値calXposOffset、calYposOffsetを求め、押圧位置の座標Xp、Ypを表しても良い。
次に、位置オフセット値calXposOffset、calYposOffsetをを用いて、押圧位置の座標Xp、Ypを中央座標からの値(すなわち座標Xpos、Ypos)とする。なお、座標Xpos、Yposは、例えば以下の式(19)を用いて求めると良い。
次に、上述した画面生成手段49により生成され、塗布動作評価装置10に表示される画面例について説明する。図11は、塗布動作中に示される表示画面の一例を示す図である。
次に、各塗布動作と評価との関係について説明する。図13は、各塗布動作とin vitro SPF予測値との関係を示す図である。図13の例では、塗布動作評価装置10を用いて、「Sample A」を塗布する際に、「塗布圧(押圧力)」、1ストローク当りの「速度(秒)」、「プレート支持」、「塗布時間(秒)」を変化させたときの塗布面に対するin vitro SPFの予測値が示されている。この予測値によれば、例えば「塗布圧」を変化させるとin vitro SPFの予測値が著しく変動していることが示されている。なお、従来では、塗布方法を定義する際に塗布量や塗布時間等が規定されることがあったが、塗布圧が変動因子として考慮されることがなかった。
