Claims (4)
- トンネルと、該トンネル内に被検体を通過させる搬送手段と、前記トンネル内に配置された検出手段とを有し、
前記検出手段は、前記トンネル内を通過している前記被検体を停止させることなく圧迫する押圧部と、前記被検体から漏れ出た特定ガスを検出する検出部と、前記トンネル内に、前記特定ガスが含まれない気体、または、前記特定ガスの含有濃度が所定濃度の気体を導入する気体供給部とを含み、
前記搬送手段は、前記トンネル内でベルトが対向するように配置された一対のベルトコンベアを有し、前記ベルトは、厚さ方向に前記特定ガスが通り抜けることができる材質によって構成され、前記被検体は、対向する前記ベルトの間に挟まれて前記トンネル内を搬送されることを特徴とする漏れ検査装置。 - 請求項1に記載の漏れ検査装置において、前記押圧部は、前記被検体の厚さまたは幅よりも小さい間隔を開けて配置された一対の弾性体を有し、前記被検体は、前記弾性体の間を通過することにより圧迫されることを特徴とする漏れ検査装置。
- 請求項2に記載の漏れ検査装置において、前記弾性体の対は、前記搬送手段の搬送方向に沿って二対配置され、前記検出部は、前記二対の弾性体の間に配置されていることを特徴とする漏れ検査装置。
- 請求項1ないし3のいずれか1項に記載の漏れ検査装置において、前記検出部は、発泡部材と、前記発泡部材を繰り返し前記被検体に押しつけることにより圧縮伸張させる駆動機構と、前記発泡部材の前記圧縮伸張により該発泡部材の内部に取り込まれた特定ガスを吸引して検出する検出器とを有することを特徴とする漏れ検査装置。
