本考案は赤外線疵検査装置の赤外線ウィンド構造の改良
に関する。[Detailed Description of the Invention] The present invention relates to an improvement in the infrared window structure of an infrared defect inspection device.
近時、赤外線に対し著しく応答の早い
ＨｇＣｄＴｅ、 Ｐｂ５ｎＴｅ等の赤外線検知器が開発
されたため、鋼材などの熱間圧延時にその表面の疵を検
出する赤外線疵検査装置に応用されている。Recently, infrared detectors made of materials such as HgCdTe and Pb5nTe, which have extremely fast response to infrared rays, have been developed and are being applied to infrared flaw inspection equipment for detecting flaws on the surface of steel materials during hot rolling.
この疵検査装置は第１図に示す如く被検査物１の表面を
走査して各部分より放射される赤外線２を装置３の中に
設けられた赤外線検知器により検知し、その差異により
疵の有無を検出するようになっている。As shown in Fig. 1, this flaw inspection device scans the surface of an object to be inspected 1 and detects infrared rays 2 emitted from each part using an infrared detector installed in the device 3, and detects flaws based on the differences. It is designed to detect the presence or absence.
そして被検査物１の下方から検査する場合には遮蔽板４
が設けられてはいるが装置３の赤外線ウィンド５にはダ
ストなどが付着する不具合があるため、第２図にその断
面図を示す如くウィンド５の周囲に圧縮空気６を吹出す
ノズル７を配置してダストの侵入を防止している。When inspecting the object to be inspected 1 from below, a shielding plate 4 is used.
However, since the infrared window 5 of the device 3 has a problem with dust etc. adhering to it, a nozzle 7 for blowing out compressed air 6 is arranged around the window 5 as shown in a cross-sectional view in Fig. 2. This prevents dust from entering.
ところがこの装置も空気の渦流によってダストが巻込ま
れウィンドに付着する恐れがあり、また一度付着しタタ
ストを外部へ放出することができない。However, even with this device, there is a risk that dust will be drawn in by the vortex of air and adhere to the window, and once it has adhered, it will not be possible to release the dust to the outside.
本考案はこの欠点を改良するために案出されたものであ
る。The present invention was devised to improve this drawback.
このため本考案においては、赤外線を透す材料で形成し
た矩形の窓を具備した赤外線疵検査装置において、舷窓

辺に圧縮空気を吹出す複数個のノズルを設け、その一方
の長辺のノズルを窓の方向に傾斜させ、他方の長辺のノ
ズルをフードの開口部の方向に傾斜させて配置したこと
を特徴とするものである。Therefore, in the present invention, in an infrared defect inspection device equipped with a rectangular window made of a material that transmits infrared rays, a hood is provided in the porthole, and a plurality of compressed air are blown out from opposite long sides of the base of the hood. The hood is characterized by having two nozzles, the nozzle on one long side being inclined towards the window, and the nozzle on the other long side being inclined towards the opening of the hood.
以下、添付図面に基づいて本考案の実施例につき詳細に
説明する。Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
第３図に実施例の正面断面図を示腰第４図に第３図のＩ
Ｖ−ＩＶ線における断面図を示す。Fig. 3 shows a front sectional view of the embodiment, and Fig. 4 shows I of Fig. 3.
A sectional view taken along the line V-IV is shown.
第３図において符号８は疵検査装置本体、９は赤外線を
通す物質で形成された矩形の窓であり、１ｏはその窓の
ふちから立上るフードである。In FIG. 3, reference numeral 8 is a main body of the flaw inspection apparatus, 9 is a rectangular window formed of a material that transmits infrared rays, and 1o is a hood rising from the edge of the window.
このフード１０の基部の相対する長辺のそれぞれに圧縮
空気を吹き出す複数個のノズル１１が設けられている。A plurality of nozzles 11 for blowing out compressed air are provided on each of the opposing long sides of the base of the hood 10.
このノズル１１の方向は第４図に示す如く一方の長辺の
ノズルｌｌａは空気を下方の窓９に吹き付ける方向に傾
斜させ、他方の長辺ノズル１１ｂはフード１０の開口部
の方向に傾斜して設けられている。As shown in FIG. 4, the nozzles 11 are oriented so that the nozzle lla on one long side is inclined in the direction of blowing air toward the lower window 9, and the nozzle 11b on the other long side is inclined in the direction of the opening of the hood 10. It is provided.
このように構成された本実施例は空気送入口１２より圧
縮空気を送入すれば、一方のノズル１１ａより吹き出し
た空気は窓９の表面に付着したダストを吹き飛ばす。In this embodiment configured as described above, when compressed air is fed through the air inlet 12, the air blown out from one nozzle 11a blows away dust attached to the surface of the window 9.
この吹き飛ばされたダストは他方のノズルｌｌｂより吹
き出された空気によりフード１０の外方に放出される。This blown dust is discharged to the outside of the hood 10 by the air blown out from the other nozzle llb.
以上の如く本考案のウィンド構造は窓にフードを設ける
と共にその基部にノズルを設けくそのノズルにそれぞれ
方向性を持たせることにより、フード内の空気の流れに
指向性を与えフード内へのダストの侵入を防止し、また
既に窓に付着しているダストも外部へ放出することが可
能であり、疵検査装置の保守性の向上に寄与するもので
ある。As described above, the window structure of the present invention provides a hood on the window and a nozzle at the base of the hood.By giving each nozzle directionality, the airflow inside the hood is directed and the dust is removed from the hood. It is possible to prevent dust from entering the window, and also to release dust that has already adhered to the window to the outside, contributing to improving the maintainability of the flaw inspection device.
