- the plurality of receiving units 21 having the receiving surfaces 21a for receiving the ultrasonic waves W are arranged with They are arranged in an array in cross directions. Therefore, by reducing the area of the receiving surface 21a of each receiving portion 21, it is possible to inspect the separation of the container member 101 at the joint portion 103 (especially the base end portion 103A) with high accuracy. In addition, by arranging the receivers 21 in an array, the total area of the receiver surface 21a can be increased. As a result, the entire joint portion 103 including the base end portion 103A can be inspected with high precision and in a short time.
- the transmitter main body 11 is arranged so that at least the ultrasonic waves W transmitted from the transmission surface 13a of the transmitter main body 11 are reflected by the mirror 12 and directed toward the joint portion 103 of the packaging container 100. good too.

- the transmission surface 13a of the transmission unit main body 11 may be a flat surface as shown in FIG. 5, for example.
- the ultrasonic waves W transmitted from the transmission surface 13 a of the transmitter main body 11 are reflected by the mirror 12 and propagate toward the joint portion 103 of the packaging container 100 without being converged. Therefore, the shape of the ultrasonic wave W orthogonal to the propagation direction (Y-axis positive direction) of the ultrasonic wave W from the mirror 12 toward the joint portion 103 is planar regardless of the position in the Y-axis direction.
- the plurality of receivers 21 constituting the receiver unit 20 are arranged in a matrix corresponding to the planar ultrasonic waves W described above. That is, the plurality of receivers 21 are arranged in two directions (X-axis direction and Z-axis direction) orthogonal to the Y-axis direction.

Description
この出願は、2021年5月31日に出願された日本国特願2021-090827号を基礎とする優先権を主張し、その開示の全てをここに取り込む。
特許文献1には、容器用部材の接合部分における剥離を検査するための超音波検査装置が開示されている。この種の超音波検査装置は、超音波を送信する送信部を有し、送信部から送信されて接合部分を透過した超音波を受信して解析することで、接合部分に剥離が生じているか否かを判定する。従来の超音波検査装置では、送信部から接合部分に向けて、接合部分において容器用部材の縁が重なる方向に超音波を送信している。
以下、図1~4を参照して本開示の第一実施形態について説明する。
図1に示すように、本実施形態の超音波検査装置1は、超音波Wを利用して包装容器100の検査を行う。本実施形態における包装容器100は、シート状の容器用部材101の縁を重ねて接合することで内部に収容空間102を形成した容器である。図示例の包装容器100は、1枚の容器用部材101によって構成されているが、例えば2枚の容器用部材101によって構成されてもよい。超音波検査装置1は、包装容器100のうち、容器用部材101を重ねて接合した接合部分103における容器用部材101の剥離を検査する。以下の説明では、容器用部材101のうち接合されずに収容空間102を形成する包装容器100の部位を、非接合部分105と呼ぶ。
送信部10は、包装容器100の接合部分103が非接合部分105の外面105aに対して直交する方向に突出した状態で、接合部分103に向けて超音波Wを送信する(照射する)。送信部10は、特に接合部分103のうち非接合部分105側に位置する基端部103Aに向けて積極的に超音波Wを送信するように構成されている。
送信部本体11は、超音波Wを送信する部位である。本実施形態の送信部本体11は、送信素子(照射素子)13と、保持ケース14と、を有する。送信素子13は、超音波Wを送信する送信面(照射面)13aを有する。保持ケース14は、送信素子13の送信面13aが外部に露出するように送信素子13を保持する。本実施形態の保持ケース14は、送信面13aの周縁全体を覆うように送信素子13を保持する。すなわち、送信素子13の送信面13aは、保持ケース14の所定部位によって囲まれている。
以下、本実施形態の送信部本体11及びミラー12についてより具体的に説明する。
本実施形態では、送信部本体11から送信された超音波Wが収束する位置よりも手前にミラー12の反射面12aが位置する。このため、ミラー12の反射面12aにおいて反射してY軸正方向に伝播する超音波Wは、図4に示すように、Y軸正方向に向かうにしたがってX軸方向において収束し、Z軸方向には収束しない。これにより、ミラー12の反射面12aにおいて反射した超音波Wは、収束した位置において、X軸方向における長さが小さく、Z軸方向における長さが大きい線状となる。
複数の受信部21は、超音波Wが収束した位置に厳密に配置されることに限らず、例えば超音波Wが収束した位置よりも送信部10から離れた方向(Y軸正方向)にずらした位置に配置されてよい。ただし、複数の受信部21は、できる限り超音波Wが収束した位置の近くに配置されることがより好ましい。図4に例示するように、超音波Wが包装容器100の接合部分103あるいはその近傍で収束する場合、複数の受信部21はY軸方向において接合部分103の近くに配置されることが好ましい。
接合部分103における剥離の有無の判定は、例えば、検査対象である接合部分103を透過して受信部21で受信した超音波Wの波形(検査対象波形)を、剥離が生じていない接合部分103を透過して受信部21で受信した場合の超音波Wの波形(リファレンス波形)と比較することで行われる。例えば、リファレンス波形の位相と検査対象波形の位相との相関値を計算し、相関値が高い場合には接合部分103に剥離が生じていないと判定し、相関値が低い場合には接合部分103に剥離が生じていると判定する。
送信面13aの周縁領域13a2から送信される超音波W2の強度は、送信面13aの内側領域13a1から送信される超音波W1の強度よりも低いことがある。この場合には、従来のように、送信部本体11の送信面13aから容器用部材101が重なる方向に向けて直接超音波Wを送信すると、接合部分103の基端部103Aに到達する超音波Wの強度が低く、接合部分103に剥離が生じているか否かを正しく判定できない。これに対し、本実施形態の超音波検査装置1において、ミラー12は、送信面13aの内側領域13a1から送信されたビーム状の超音波Wを反射する。このため、ミラー12において反射したビーム状の超音波Wの強度は一様となる。これにより、ミラー12において反射した強度が一様の超音波Wを、容器用部材101が重なる方向に向けて伝播させることで、接合部分103に剥離が生じているか否かを正しく判定することができる。
複数の受信部21をマトリクス状に配列された構成では、複数の受信部21をアレイ状に配列した場合と同様の効果を奏する。
次に、図7を参照して本開示の第二実施形態について説明する。第二実施形態では、第一実施形態と同様の構成要素について同一符号を付す等して、その説明を省略する。
送信部10Dの送信面13aから送信される超音波Wの送信方向は、Y軸方向(容器用部材101が重なる方向)において送信部10Dから接合部分103に向かうにしたがって、Z軸負方向(非接合部分105に対する接合部分103の突出方向と逆の方向)に向かうように傾斜している。具体的に、送信部10Dの送信部本体11は、その送信面13aがY軸正方向側(接合部分103側)及びZ軸負方向側(非接合部分105の外面105a側)に向くように傾斜状態で配置されている。これにより、送信部10Dからの超音波Wの送信方向が上記したように傾斜する。
また、第二実施形態の超音波検査装置1Dでは、送信部10Dから送信される(照射される)超音波Wの送信方向(照射方向)が、Y軸方向(容器用部材101が重なる方向)において送信部10Dから接合部分103に向かうにしたがって、Z軸負方向(非接合部分105に対する接合部分103の突出方向と逆の方向)に向かうように傾斜している。このため、送信部本体11から送信された超音波Wを、容易に接合部分103の基端部103Aに到達させることができる。特に、送信部10Dの送信面13aの内側領域13a1から送信された超音波W(すなわち、強度が一様である超音波W)を、容易に接合部分103の基端部103Aに到達させることができる。
次に、図8を参照して本開示の第三実施形態について説明する。第三実施形態では、第一、第二実施形態と同様の構成要素について同一符号を付す等して、その説明を省略する。
次に、図9を参照して本開示の第四実施形態について説明する。第四実施形態では、第三実施形態と同様の構成要素について同一符号を付す等して、その説明を省略する。
また、第四実施形態の超音波検査装置1Fにおいて、送信部10Fは、送信面13aに直交する方向(Y軸方向)から見て、送信面13aの周縁のうち保持ケース14Eによって覆われていない部分から送信面13aの外側に突出する突起15Fを有する。これにより、包装容器100の接合部分103の基端部103Aに剥離が生じているか否かをより正しく判定することが可能となる。以下、この点について説明する。
