Description

本発明は、Ｘ線検査装置に関するものである。   The present invention relates to an X-ray inspection apparatus.

搬送機構によって搬送される被検査物にＸ線を照射するＸ線照射部と、前記被検査物を透過したＸ線を検知するＸ線検知部と、前記Ｘ線照射部と前記Ｘ線検知部とを覆う本体カバー部とを備え、この本体カバー部に設けられる一対の開口部を通じて本体カバー部内に搬入される被検査物に異物が混入されているか否かを検査するＸ線検査装置においては、例えば特許文献１に開示されるように、鉛を含有する暖簾状のＸ線遮蔽カーテンを開口部に設けて外部へのＸ線の漏出を防止する場合が多い。   An X-ray irradiating unit that irradiates the inspection object conveyed by the conveying mechanism with X-rays, an X-ray detection unit that detects X-rays transmitted through the inspection object, the X-ray irradiation unit, and the X-ray detection unit In an X-ray inspection apparatus for inspecting whether or not a foreign object is mixed in an inspection object carried into the main body cover portion through a pair of openings provided in the main body cover portion. For example, as disclosed in Patent Document 1, a warm X-ray shielding curtain containing lead is often provided in the opening to prevent leakage of X-rays to the outside.

この場合、Ｘ線遮蔽カーテンによるＸ線の外部への漏出をより確実に防止するためには、１つの被検査物の本体カバー部内への搬入、Ｘ線検査、搬出が完全に終わるまでは次の被検査物を搬入することはできない。   In this case, in order to more reliably prevent the X-ray from leaking out by the X-ray shielding curtain, it is necessary to carry in until one inspection object is completely carried into the main body cover, X-ray inspection, and unloading. The inspection object cannot be carried in.

そこで、例えば、特許文献２には、単に開口部にＸ線遮蔽カーテンを設けた場合よりも外部へのＸ線の漏出を小さくし、且つ、被検査物の搬送及びＸ線検査を連続的に行えるように、本体カバー部の開口部の搬送上流側及び搬送下流側に夫々トンネル部を設けることでＸ線減衰領域を形成すると共に、各開口部を開閉するＸ線遮蔽板を所定のタイミングで開閉駆動することで、上記課題を解決しようとした技術が提案されている。   Therefore, for example, in Patent Document 2, the leakage of X-rays to the outside is made smaller than when an X-ray shielding curtain is simply provided in the opening, and the conveyance of the inspection object and the X-ray inspection are continuously performed. The X-ray attenuation region is formed by providing tunnel portions on the transport upstream side and transport downstream side of the opening portion of the main body cover portion so that the X-ray shielding plate for opening and closing each opening portion can be opened at a predetermined timing. There has been proposed a technique that attempts to solve the above-described problem by driving to open and close.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

供給側搬送機構６側から供給される被検査物１に中央搬送機構５上でＸ線を照射することで、この被検査物１に異物が混入しているか否かの確認や被検査物の非破壊検査等を行い、排出側搬送機構７側から排出する。   By irradiating the inspection object 1 supplied from the supply-side conveyance mechanism 6 side with X-rays on the central conveyance mechanism 5, it is possible to confirm whether or not foreign substances are mixed in the inspection object 1 and the inspection object. A non-destructive inspection or the like is performed and discharged from the discharge-side transport mechanism 7 side.

この際、Ｘ線照射後の前記被検査物１を排出する排出作動信号が入力された際（例えば排出スイッチを押下した際）、排出側搬送機構７により排出側カバー部11内の当該被検査物１を搬送排出すると共に、当該被検査物１の検査画像を画像表示手段に表示することができ、例えば当該検査画像を目視検査する検査者が排出スイッチを押下することで順次搬送される被検査物の検査画像を連続的にチェックすることが可能となる。   At this time, when a discharge operation signal for discharging the inspection object 1 after X-ray irradiation is input (for example, when a discharge switch is pressed), the discharge side transport mechanism 7 causes the inspection in the discharge side cover portion 11 to be inspected. The inspection object 1 can be conveyed and discharged, and the inspection image of the inspection object 1 can be displayed on the image display means. For example, an inspection person who visually inspects the inspection image presses the discharge switch to sequentially convey the inspection object 1. It is possible to continuously check the inspection image of the inspection object.

また、例えば本体カバー部４、供給側カバー部10及び排出側カバー部11の各開口部８に設けたＸ線遮蔽体９が所定の状態の場合のみ、Ｘ線照射部２からのＸ線照射を許容するように構成することで、外部にＸ線が漏出することがより確実に防止できるのは勿論、中央搬送機構５の搬送速度を被検査物１の位置に応じて制御することで、例えば、Ｘ線検査前は供給側搬送機構６と同じ低速度で搬送し、Ｘ線検査後は排出側搬送機構７と同じ高速度で搬送するように制御することで、より効率的な連続搬送が可能となり、よって、Ｘ線の外部への漏出をより確実に防止しつつ被検査物１の一層効率的な連続搬送が可能となる。   For example, the X-ray irradiation from the X-ray irradiation unit 2 is performed only when the X-ray shield 9 provided in each opening 8 of the main body cover unit 4, the supply side cover unit 10 and the discharge side cover unit 11 is in a predetermined state. By controlling the transport speed of the central transport mechanism 5 according to the position of the inspection object 1, of course, it is possible to prevent X-rays from leaking to the outside more reliably. For example, before the X-ray inspection, it is transported at the same low speed as the supply-side transport mechanism 6, and after the X-ray inspection, it is controlled to transport at the same high speed as the discharge-side transport mechanism 7, thereby enabling more efficient continuous transport. Therefore, the inspection object 1 can be more efficiently and continuously conveyed while preventing leakage of X-rays to the outside more reliably.

A belt conveyor (supply conveyor) as the supply-side transport mechanism 6 is provided on the upstream side of the central transport mechanism 5 and a belt conveyor (discharge conveyor) as the discharge-side transport mechanism 7 is provided on the downstream side of the transport. In the figure, reference numeral 14 denotes a leg portion of the supply-side transport mechanism 6, and 15 denotes a leg portion of the discharge-side transport mechanism 7.

また、本実施例においては、中央搬送機構５、供給側搬送機構６及び排出側搬送機構７は、各コンベヤの上面（被検査物１の搬送面）が略水平で且つこの搬送面の高さが略同一となるように設定している。尚、供給側搬送機構６の搬送上流側開口部８にはエア駆動シャッター17が設けられている。   In the present embodiment, the central transport mechanism 5, the supply-side transport mechanism 6 and the discharge-side transport mechanism 7 are such that the upper surface of each conveyor (the transport surface of the inspection object 1) is substantially horizontal and the height of this transport surface. Are set to be substantially the same. Note that an air-driven shutter 17 is provided in the transport upstream side opening 8 of the supply side transport mechanism 6.

中央搬送機構５は遮蔽箱体の本体カバー部４により覆われ、供給側搬送機構６及び排出側搬送機構７は夫々供給側カバー部10及び排出側カバー部11により覆われている。従って、装置本体の搬送上流側及び搬送下流側にはトンネル状の供給側通路及び排出側通路が形成され、これらによって装置本体からのＸ線の漏出が効果的に防止される。   The central transport mechanism 5 is covered with a main body cover portion 4 of a shielding box, and the supply-side transport mechanism 6 and the discharge-side transport mechanism 7 are covered with a supply-side cover portion 10 and a discharge-side cover portion 11, respectively. Accordingly, a tunnel-like supply-side passage and a discharge-side passage are formed on the transport upstream side and the transport downstream side of the apparatus main body, thereby effectively preventing leakage of X-rays from the apparatus main body.

また、各カバー部の開口部８に夫々設けられるＸ線遮蔽体９（Ｘ線遮断カーテン）としては、図２，３に図示したような、Ｘ線を遮断し得る金属製（ステンレス製）の板状体18が採用されている。この板状体18は、搬送機構により搬送される被検査物１の搬送移動によって押動された際にこの被検査物１の移動を妨げないように搬送方向側に所定角度回動可能に軸支部により軸支されている。   Further, as the X-ray shields 9 (X-ray blocking curtains) provided in the openings 8 of the respective cover portions, as shown in FIGS. 2 and 3, a metal (stainless steel) that can block X-rays is used. A plate-like body 18 is employed. The plate-like body 18 is pivotable by a predetermined angle in the conveyance direction so as not to hinder the movement of the inspection object 1 when pushed by the movement movement of the inspection object 1 conveyed by the conveyance mechanism. It is pivotally supported by the branch.

具体的には、軸支部は、板状体18の上部に固着される軸部19と、この軸部19（の両端部）を回動自在に支持する支持凹部20とで構成されている。各支持凹部20は、各搬送機構の脚部にして各カバー部の開口部８の近傍位置（内方側所定位置）に夫々立設される支持体21の上端部に設けられている。   Specifically, the shaft support portion is composed of a shaft portion 19 fixed to the upper portion of the plate-like body 18 and a support concave portion 20 that rotatably supports the shaft portion 19 (both ends thereof). Each support recess 20 is provided at an upper end portion of a support body 21 erected at a position near the opening 8 of each cover portion (a predetermined position on the inner side) as a leg portion of each transport mechanism.

即ち、Ｘ線遮蔽体９は自重により常態では搬送機構に対して垂下した閉状態となり、被検査物１がこのＸ線遮蔽体９の下側を通過する際にのみ押し上げ回動されて開状態となる。従って、このＸ線遮蔽体９を開閉駆動する駆動機構は不要となり、それだけコスト安となる。   That is, the X-ray shield 9 is in a closed state in which the X-ray shield 9 is suspended with respect to the transport mechanism under its own weight, and is opened only when the inspection object 1 passes below the X-ray shield 9. It becomes. Therefore, a drive mechanism for opening and closing the X-ray shield 9 is not necessary, and the cost is reduced accordingly.

また、各支持体21にはＸ線遮蔽体９の開閉状態を検知する開閉検知センサ12が夫々設けられている。具体的には本実施例においては、近接センサ（誘導型若しくは静電容量型）を採用している。この近接センサでＸ線遮蔽体９を検知した際にリミットスイッチがＯＮとなり、閉状態を検知することができる。   Each support 21 is provided with an open / close detection sensor 12 for detecting the open / closed state of the X-ray shield 9. Specifically, in this embodiment, a proximity sensor (inductive type or capacitive type) is employed. When the proximity sensor detects the X-ray shield 9, the limit switch is turned on, and the closed state can be detected.

また、図中符合23はＸ線遮蔽体９の上下位置調整用の上下位置調整部、24はＸ線遮蔽体９の左右位置調整用の左右位置調整部、25は開閉検知センサ12の左右位置調整用のセンサ位置調整部、26はＸ線遮蔽体９の常態における傾斜角度調整部、27はＸ線遮蔽体９とコンベヤ上面との隙間調整用の隙間調整部、28は抜け止め部である。   In the figure, reference numeral 23 is a vertical position adjusting unit for adjusting the vertical position of the X-ray shield 9, 24 is a horizontal position adjusting unit for adjusting the horizontal position of the X-ray shield 9, and 25 is a horizontal position of the open / close detection sensor 12. A sensor position adjustment unit for adjustment, 26 is an inclination angle adjustment unit in the normal state of the X-ray shield 9, 27 is a gap adjustment unit for adjusting the gap between the X-ray shield 9 and the upper surface of the conveyor, and 28 is a retaining portion. .

各位置調整部について具体的に説明すると、図２においては、支持体21は固定部29と該固定部29に対して調整移動可能な調整移動部30とで構成され、この固定部29と調整移動部30とは左右方向に長い長窓及びボルト・ナット等の適宜な締結部材により構成される左右位置調整部24を介して連結されている。この調整移動部30の上端部には支持凹部20が形成されたＸ線遮蔽体支持部31が上下方向に長い長窓及び適宜な締結部材により構成される上下位置調整部23を介して連結されている。また、このＸ線遮蔽体支持部31とＸ線遮蔽体９との間にボルト・ナットから成る傾斜角度調整部26が設けられている。また、Ｘ線遮蔽体支持部31に左右方向に長い長窓及び適宜な締結部材により構成されるセンサ位置調整部25を介して開閉検知センサ12を取り付けた取付板32が設けられている。   Each position adjusting unit will be described in detail. In FIG. 2, the support 21 includes a fixing unit 29 and an adjustment moving unit 30 that can be adjusted and moved with respect to the fixing unit 29. The moving part 30 is connected to the moving part 30 via a left / right position adjusting part 24 constituted by an appropriate fastening member such as a long window and a bolt / nut. An X-ray shield support portion 31 in which a support recess 20 is formed is connected to an upper end portion of the adjustment moving portion 30 through a vertical position adjustment portion 23 configured by a long window and an appropriate fastening member in the vertical direction. ing. Further, an inclination angle adjusting unit 26 composed of bolts and nuts is provided between the X-ray shield support 31 and the X-ray shield 9. The X-ray shield support part 31 is provided with a mounting plate 32 to which the open / close detection sensor 12 is attached via a sensor position adjusting part 25 configured by a long window in the left-right direction and an appropriate fastening member.

また、図３においては、支持体21は固定部29と該固定部29に対して調整移動可能な調整移動部30とで構成され、この固定部29と調整移動部30とは左右方向に長い長窓及びボルト・ナット等の適宜な締結部材により構成される左右位置調整部24を介して連結されている。この調整移動部30の上端部には支持凹部20が形成されている。また、このＸ線遮蔽体支持部31とＸ線遮蔽体９との間にボルト・ナットから成る傾斜角度調整部26が設けられている。また、図３においては、２枚の板状体18を上下方向に長い長窓及び適宜な締結部材により構成される隙間調整部27を介して連結しており、この下側の板状体18に検知用平板部22を設けている。   In FIG. 3, the support body 21 includes a fixed portion 29 and an adjustment moving portion 30 that can be adjusted and moved with respect to the fixed portion 29. The fixed portion 29 and the adjustment moving portion 30 are long in the left-right direction. They are connected via a left / right position adjustment unit 24 constituted by an appropriate fastening member such as a long window and a bolt / nut. A support recess 20 is formed at the upper end of the adjustment moving unit 30. Further, an inclination angle adjusting unit 26 composed of bolts and nuts is provided between the X-ray shield support 31 and the X-ray shield 9. In FIG. 3, two plate-like bodies 18 are connected via a gap adjusting portion 27 constituted by a long window that is long in the vertical direction and an appropriate fastening member, and the lower plate-like body 18. Is provided with a detecting flat plate portion 22.

従って、各位置調整部の長窓とボルトとの位置関係等を調整することで、被検査物１に応じてＸ線遮蔽体９による遮蔽位置を適宜設定調整することが可能となる。   Therefore, by adjusting the positional relationship between the long window and the bolt of each position adjusting unit, the shielding position by the X-ray shield 9 can be appropriately set and adjusted according to the object 1 to be inspected.

また、供給側搬送機構６の搬送下流側開口部８の近傍位置、中央搬送機構５の搬送上流側開口部８の近傍位置及び搬送下流側開口部８の近傍位置、排出側搬送機構７の搬送上流側開口部８の近傍位置には、夫々被検査物１を検知する位置検知センサａ，ｂ，ｃ，ｄ（位置確認センサａ，ｂ，ｃ，ｄ）が設けられている。この位置検知センサａ，ｂ，ｃ，ｄとしては近接センサ（誘導型若しくは静電容量型）が採用されている。   In addition, the position near the transport downstream side opening 8 of the supply side transport mechanism 6, the position near the transport upstream side opening 8 of the central transport mechanism 5 and the position near the transport downstream side opening 8, the transport of the discharge side transport mechanism 7 Position detection sensors a, b, c, and d (position confirmation sensors a, b, c, and d) that detect the inspection object 1 are provided in the vicinity of the upstream opening 8. As the position detection sensors a, b, c, and d, proximity sensors (inductive type or capacitance type) are employed.

上記の各検知センサはパーソナルコンピュータ等の情報処理装置と接続され、各検知情報を元にＸ線照射部２及び中央搬送機構５の搬送速度を制御（中央搬送機構５駆動用のブラシレスモータを制御）するように構成している。尚、供給側搬送機構６及び排出側搬送機構７は夫々インバータ制御としている。   Each detection sensor is connected to an information processing apparatus such as a personal computer, and controls the conveyance speed of the X-ray irradiation unit 2 and the central conveyance mechanism 5 based on each detection information (controls the brushless motor for driving the central conveyance mechanism 5). ). The supply-side transport mechanism 6 and the discharge-side transport mechanism 7 are each controlled by an inverter.

本実施例においては、供給側搬送機構６の搬送速度を排出側搬送機構７より低速（一定速）に設定し（排出側搬送機構７の搬送速度は供給側搬送機構６より高速且つ一定速）、搬送速度制御機構は、中央搬送機構５の搬送速度を供給側搬送機構６の搬送速度及び排出側搬送機構７の搬送速度と同速度に設定し得るように構成している。また、搬送速度は検査対象に応じて適宜調整設定する。   In this embodiment, the transport speed of the supply-side transport mechanism 6 is set to a lower speed (constant speed) than the discharge-side transport mechanism 7 (the transport speed of the discharge-side transport mechanism 7 is higher and constant speed than the supply-side transport mechanism 6). The transport speed control mechanism is configured so that the transport speed of the central transport mechanism 5 can be set to the same speed as the transport speed of the supply-side transport mechanism 6 and the transport speed of the discharge-side transport mechanism 7. Further, the conveyance speed is appropriately adjusted and set according to the inspection object.

例えば、被検査物１である魚等の食品が収納された１つのトレーを、中央搬送機構５において複数回（例えば２回）撮影する場合（被検査物１の全長が長く、１回の撮影では検査できない場合）、図１１、１２のフローチャートのように制御する。   For example, when one tray containing food such as fish that is the inspection object 1 is imaged a plurality of times (for example, twice) in the central transport mechanism 5 (the inspection object 1 is long and has one image) Then, control is performed as shown in the flowcharts of FIGS.

装置の電源を入れ、Ｘ線照射スイッチを入れる。この際、全ての開閉検知センサ12のリミットスイッチがＯＮでなければＸ線照射はされない。   Turn on the device and turn on the X-ray irradiation switch. At this time, X-ray irradiation is not performed unless the limit switches of all the open / close detection sensors 12 are ON.

続いて、コンベヤを起動し、シャッター17を開き、被検査物１である第１トレーを供給側搬送機構６の搬送上流側開口部から投入する（図４）。この際、トレー位置確認センサａでトレーからの反射光が受光されリミットスイッチがＯＮになると供給コンベヤを停止し（図５）、シャッター17を閉じた後、供給コンベアを起動し、中央搬送機構５へと搬送する（図６）。   Subsequently, the conveyor is activated, the shutter 17 is opened, and the first tray, which is the object to be inspected 1, is inserted from the opening on the upstream side of the supply side transport mechanism 6 (FIG. 4). At this time, when the reflected light from the tray is received by the tray position confirmation sensor a and the limit switch is turned on, the supply conveyor is stopped (FIG. 5), the shutter 17 is closed, the supply conveyor is started, and the central transport mechanism 5 (Fig. 6).

続いて、低速ピッチの中央搬送機構５により搬送されてトレー位置確認センサｃのリミットスイッチがＯＮになると本体コンベヤを停止し、１コマ目の撮影を行い（図７）、その後、本体コンベヤを起動し高速ピッチでトレーを搬送し、２コマ目の撮影を行う（図８）。尚、第１トレーの１コマ目の撮影の際、第２トレーを第１トレーと同様の手順で供給側搬送機構６上に搬入し待機させる（図６，７）。   Next, when the limit switch of the tray position confirmation sensor c is turned on by being transported by the central transport mechanism 5 at a low speed pitch, the main body conveyor is stopped, the first frame is taken (FIG. 7), and then the main body conveyor is started. Then, the tray is conveyed at a high speed and the second frame is shot (FIG. 8). When the first frame of the first tray is photographed, the second tray is carried onto the supply-side transport mechanism 6 in the same procedure as that for the first tray and is waited (FIGS. 6 and 7).

続いて、２コマ目の撮影後、本体コンベヤは高速で第１トレーを排出コンベヤ側へ搬送し、トレー位置確認センサｄに検知されて排出コンベア上で停止した第１トレーは（図９）、（３０秒が経過するか）トレー排出スイッチがＯＮされるとＸ線遮蔽体９を通って排出コンベヤから排出され、第１トレーの検査が終了する（図１０）。ここで、トレー位置確認センサｄでトレーが検知されない場合には、所定時間経過後アラームで報知すると共に装置を停止する。また、第２トレーは、撮影が完了するまで（第１トレーが排出コンベヤから排出されるまで）本体カバー部４の搬送上流側開口部を閉塞するＸ線遮蔽体９の手前位置（センサｂの位置）で待機し、その後、第１トレーと同様の手順で撮影、排出される（図８〜１０）。   Subsequently, after photographing the second frame, the main conveyor conveys the first tray to the discharge conveyor at a high speed, and the first tray detected by the tray position confirmation sensor d and stopped on the discharge conveyor is (FIG. 9). (If 30 seconds elapses) When the tray discharge switch is turned on, the tray is discharged from the discharge conveyor through the X-ray shield 9, and the inspection of the first tray is completed (FIG. 10). Here, when the tray is not detected by the tray position confirmation sensor d, an alarm is given after a predetermined time has elapsed, and the apparatus is stopped. In addition, the second tray is positioned before the X-ray shield 9 that closes the conveyance upstream side opening of the main body cover unit 4 (until the sensor b) until imaging is completed (until the first tray is discharged from the discharge conveyor). At the position), and then the image is taken and ejected in the same procedure as the first tray (FIGS. 8 to 10).

以上のように制御することで、複数回の撮影が必要で間欠送りを余儀なくされる場合であっても、搬送のロスを最小限に抑え可及的にハイスループットな処理が可能となる。   By controlling as described above, even when a plurality of shootings are required and intermittent feeding is unavoidable, it is possible to perform high-throughput processing as much as possible while minimizing transport loss.

また、本実施例においては、Ｘ線照射後の被検査物１を排出する排出作動信号が入力された際、排出側搬送機構７により排出側カバー部11内の当該被検査物１を搬送排出すると共に、当該被検査物１の画像を画像表示手段に表示する連動制御機構を備えているため、
Ｘ線照射後の前記被検査物１を排出する排出作動信号が入力された際（排出スイッチを押下した際）、排出側搬送機構７により排出側カバー部11内の当該被検査物１を搬送排出すると共に、当該被検査物１の検査画像を画像表示手段に表示することができ、例えば当該検査画像を目視検査する検査者が排出スイッチを押下することで順次搬送される被検査物の検査画像を連続的にチェックすることが可能となる。尚、連動制御機構としては上述のパーソナルコンピュータ等の情報処理装置を採用できる。 Further, in this embodiment, when a discharge operation signal for discharging the inspection object 1 after X-ray irradiation is input, the inspection object 1 in the discharge side cover portion 11 is conveyed and discharged by the discharge side conveyance mechanism 7. And an interlocking control mechanism for displaying the image of the inspection object 1 on the image display means.
When a discharge operation signal for discharging the inspection object 1 after X-ray irradiation is input (when the discharge switch is pressed), the inspection object 1 in the discharge side cover 11 is transferred by the discharge side transfer mechanism 7. While being ejected, the inspection image of the inspection object 1 can be displayed on the image display means. For example, the inspection of the inspection object which is sequentially conveyed by an inspector who visually inspects the inspection image by pressing the discharge switch Images can be checked continuously. As the interlock control mechanism, an information processing apparatus such as the above-described personal computer can be employed.

具体的には、排出スイッチが押下されることで排出作動信号が入力された際、排出側搬送機構７を駆動して排出側カバー部11内の被検査物１を下流側（排出台34）へ搬送排出すると共に、撮像したＸ線透過画像をディスプレイ33に表示するように構成している。   Specifically, when a discharge operation signal is input by pressing the discharge switch, the discharge-side transport mechanism 7 is driven to move the object 1 in the discharge-side cover portion 11 downstream (discharge table 34). And the captured X-ray transmission image is displayed on the display 33.

また、本実施例においては、供給側搬送機構６及び排出側搬送機構７は中央搬送機構５に着脱自在に設け、この中央搬送機構５に連設状態に設けられる供給側搬送機構６から供給側カバー10が外されたこと及び排出側搬送機構７から排出側カバー11が外されたことを検知してＸ線の照射を制御する検知制御機構を設けている。検知制御機構としては着脱検知センサ（近接センサ）と上述のパーソナルコンピュータ等の情報処理装置とを採用できる。   In this embodiment, the supply-side transport mechanism 6 and the discharge-side transport mechanism 7 are detachably provided on the central transport mechanism 5, and the supply-side transport mechanism 6 provided in a continuous state with the central transport mechanism 5 supplies the supply side. A detection control mechanism for detecting X-ray irradiation by detecting that the cover 10 has been removed and that the discharge-side cover 11 has been removed from the discharge-side transport mechanism 7 is provided. As the detection control mechanism, an attachment / detachment detection sensor (proximity sensor) and an information processing apparatus such as the personal computer described above can be employed.

従って、中央搬送機構５において照射されるＸ線が外部に漏出する可能性は極めて小さくなる。   Therefore, the possibility that X-rays irradiated in the central transport mechanism 5 leak to the outside is extremely small.

また、本実施例においては、供給側搬送機構６へ被検査物１の投入を許可することを表示する投入許可表示手段を設け、Ｘ線照射後の被検査物１を排出する排出作動信号が入力された際、投入許可表示手段を作動させるように前記連動制御機構を構成している。従って、被検査物１を投入する作業者は、より確実に投入が必要な状態でのみ被検査物１を投入可能となる。   Further, in the present embodiment, a loading permission display means for displaying permission of loading of the inspection object 1 to the supply-side transport mechanism 6 is provided, and a discharge operation signal for discharging the inspection object 1 after X-ray irradiation is provided. The interlock control mechanism is configured to operate the input permission display means when input. Accordingly, an operator who puts the inspection object 1 can input the inspection object 1 only in a state where it is necessary to input the inspection object more reliably.

また、本実施例においては、供給側搬送機構６に、被検査物１が投入されたこと（供給側カバー10内に存在すること）を検知する投入検知部を設け、この供給側搬送機構６の搬送上流側開口部に、前記被検査物１の投入を妨害するシャッター等の誤投入防止手段を設け、この誤投入防止手段は、前記投入検知部で前記被検査物１の投入を検知した際、後続の被検査物１の投入を妨害するように構成し、前記Ｘ線照射後の前記被検査物１を排出する排出作動信号が入力された際、前記誤投入防止手段による投入妨害が解除されるように前記連動制御機構を構成している。従って、被検査物１を投入する作業者による投入ミスは生じないこととなる。   In the present embodiment, the supply-side transport mechanism 6 is provided with an input detection unit that detects that the inspection object 1 has been input (is present in the supply-side cover 10). An erroneous insertion prevention means such as a shutter that obstructs the insertion of the inspection object 1 is provided in the opening portion on the upstream side of the conveyance, and the erroneous insertion prevention means detects the insertion of the inspection object 1 by the insertion detection unit. At this time, it is configured to prevent the subsequent inspection object 1 from being thrown in, and when a discharge operation signal for discharging the inspection object 1 after the X-ray irradiation is input, the insertion trouble by the erroneous insertion preventing means is prevented. The interlock control mechanism is configured to be released. Therefore, the insertion mistake by the operator who inputs the inspection object 1 does not occur.

具体的には、シャッター17は投入検知部で被検査物１が検知されておらず、且つ、Ｘ線の漏出がない場合には開状態（解除状態）となり、被検査物１を検知した状態では閉状態（作動状態）となるが、閉状態であっても排出作動信号が入力された際には開状態となるように連動制御機構を構成している。   Specifically, the shutter 17 is in an open state (released state) when the inspection object 1 is not detected by the input detection unit and there is no X-ray leakage, and the inspection object 1 is detected. In the closed state (actuated state), the interlock control mechanism is configured so that the open state is established when the discharge operation signal is input even in the closed state.

また、図１１、１２のフローチャートに限らず、上記連動制御機構を用いて図１４のフローチャートのように制御しても良い。   Moreover, you may control not only the flowchart of FIG. 11, 12 but like the flowchart of FIG. 14 using the said interlocking control mechanism.

以上、本実施例は、被検査物をより効率的に連続搬送可能な極めて実用性に秀れたものとなる。   As described above, the present embodiment is extremely excellent in practicality that can continuously convey the inspection object more efficiently.
