輸出入貨物用のコンテナ内や自動車に隠された銃火器、麻薬等の社会悪物質、または不正な輸出入申告物件等を摘発する手段として、コンテナを搭載した車両（以下、コンテナ車両と称す）や自動車ごと（以下、被検査物と称す）Ｘ線を遮蔽した管理領域のＸ線検査位置に搬入し、Ｘ線等の放射線を照射して被検査物を検査する検査装置が、国内にも導入されつつある。   Vehicles equipped with containers (hereinafter referred to as “container vehicles”) as a means of detecting socially harmful substances such as firearms, drugs, etc., or illegal import / export declarations hidden in containers for import / export cargo There are also inspection devices in Japan that carry in X-ray inspection positions in the management area where X-rays are shielded for each car and vehicle (hereinafter referred to as inspection objects), and inspect the inspection objects by irradiating X-rays and other radiation. It is being introduced.

このような検査設備は、コンテナ貨物の内部を車両に搭載したまま検査できる上、船舶用の大型コンテナや自動車でも、開梱したり解体することなく内部検査できるため、検査時間が大幅に短縮され、物流の効率化にもつながるので、今後益々需要が増加するものと考えられる。   Such inspection equipment can inspect the inside of the container cargo while it is mounted on the vehicle, and even a large container or car for a ship can inspect the inside without unpacking or dismantling, greatly reducing the inspection time. It will also lead to more efficient logistics, so demand will increase further in the future.

このような目的に用いられるＸ線検査方法として、例えば、その好適実施の形態を示す側面図である図８の従来の発明に係るＸ線検査方法がある（特許文献１参照）。この従来例によれば、コンテナ３３を搭載した車両３２を、遮蔽室３４を通過させ、その間に車両３２の搭載したコンテナ３３をＸ線検査する方法において、遮蔽室３４の車両用通路３５の下方にその長さ方向に沿って形成される台車用通路３６を形成している。   As an X-ray inspection method used for such a purpose, for example, there is an X-ray inspection method according to the conventional invention of FIG. 8 which is a side view showing a preferred embodiment (see Patent Document 1). According to this conventional example, in the method in which the vehicle 32 on which the container 33 is mounted passes through the shielding chamber 34 and the container 33 on which the vehicle 32 is mounted is X-ray-inspected in the meantime, below the vehicle passage 35 in the shielding chamber 34. A carriage passage 36 is formed along the length direction.

同時に、車両用通路３５と台車用通路３６の中央部付近の前後に設けられる開閉自在な遮蔽扉３７ａ，３７ｂを閉めることで、車両用通路３５と台車用通路３６内に遮蔽室３４が区画形成されている。その台車用通路３６にレール３８を敷設すると共にそのレール３８上を自走する搬送台車４０を設け、搬送台車４０でＸ線検査すべき車両３２の車輪３９を持ち上げつつ、その車両３２を等速度で遮蔽室３４を通過させることによってＸ線検査する方法である。   At the same time, by closing the openable and closable shielding doors 37a and 37b provided near the center of the vehicle passage 35 and the carriage passage 36, a shielding chamber 34 is formed in the vehicle passage 35 and the carriage passage 36. Has been. A rail 38 is laid in the carriage passage 36 and a carriage 40 is provided that is self-propelled on the rail 38, and the vehicle 32 is moved at a constant speed while lifting the wheels 39 of the vehicle 32 to be X-ray-inspected by the carriage 40. The X-ray inspection is performed by passing through the shielding chamber 34.

また、前記Ｘ線検査方法において、遮蔽室３４の上方に設けられ、遮蔽室３４を通過するコンテナ３３を搭載した車両３２に、Ｘ線照射装置３１によって等間隔で所定時間ごとにＸ線を照射すると共に、遮蔽室３４の下方に設けられたＸ線検出器４２によって透過Ｘ線を検出している。同時に、その検出した透過Ｘ線の走査画像からＸ線検査を行うＸ線検査方法である。   In the X-ray inspection method, X-rays are irradiated at regular intervals by the X-ray irradiation device 31 to the vehicle 32 equipped with the container 33 provided above the shielding chamber 34 and passing through the shielding chamber 34. In addition, transmitted X-rays are detected by an X-ray detector 42 provided below the shielding chamber 34. At the same time, it is an X-ray inspection method for performing an X-ray inspection from the detected transmission X-ray scan image.

このような従来例に係るＸ線検査について更に理解を助けるため、Ｘ線検査設備の斜視図である図９を用いて、その検査の流れについて以下説明する（非特許文献１参照）。
先ず、図９において、建屋右方向から進入ヤード５１に進入して来たコンテナ車両５０の運転手は、Ｘ線検査トンネル（遮蔽室）５２の入側遮蔽扉５３ａ前方でコンテナ車両５０を停止させ、下車する。 In order to help further understanding the X-ray inspection according to the conventional example, the flow of the inspection will be described below with reference to FIG. 9 which is a perspective view of the X-ray inspection equipment (see Non-Patent Document 1).
First, in FIG. 9, the driver of the container vehicle 50 that has entered the entrance yard 51 from the right side of the building stops the container vehicle 50 in front of the entrance-side shielding door 53 a of the X-ray inspection tunnel (shielding room) 52. Get off.

そして、前述した図示しない搬送台車（第１搬送台車）が前記車両前輪部を持ち上げ、入側遮蔽扉５３ａが開いた後、Ｘ線検査トンネル５２内を毎分２０ｍ程度の速度で自動走行する。検査トンネル５２中央部では、前記コンテナ車両５０は一旦停止され、第１搬送台車から開放されて前記台車は進入ヤードに戻る。入側遮蔽扉５３ａが閉められた後、コンテナ車両５０は、検査トンネル５２中央部で第２搬送台車によって持ち上げられ、退出ヤード５４に向かって自動走行を開始する。   Then, after the unillustrated transport cart (first transport cart) lifts the front wheel portion of the vehicle and opens the entrance-side shielding door 53a, it automatically travels in the X-ray inspection tunnel 52 at a speed of about 20 m / min. In the central portion of the inspection tunnel 52, the container vehicle 50 is temporarily stopped, released from the first transport carriage, and the carriage returns to the entry yard. After the entrance-side shielding door 53a is closed, the container vehicle 50 is lifted by the second transport carriage at the center of the inspection tunnel 52 and starts automatic travel toward the exit yard 54.

ほどなく、水平Ｘ線発生装置５５ａおよび垂直Ｘ線発生装置５５ｂからコンテナ車両５０のコンテナにＸ線が照射され、水平Ｘ線検出器５６ａおよび垂直Ｘ線検出器５６ｂによって透過Ｘ線を検出し画像データが収集される。   Soon, X-rays are emitted from the horizontal X-ray generator 55a and the vertical X-ray generator 55b to the container of the container vehicle 50, and transmitted X-rays are detected by the horizontal X-ray detector 56a and the vertical X-ray detector 56b. Data is collected.

Ｘ線照射が終了した後、出側遮蔽扉５３ｂが開き、コンテナ車両５０は退出ヤード５４に移動される。コンテナ車両５０が退出ヤード５４の所定位置まで移動した後、第２搬送台車は停止され、第２搬送台車から開放されて、前記台車は検査トンネル５２中央部に戻り、出側遮蔽扉５３ｂが閉じられる。この間、第１搬送台車は、次の車両を検査トンネル５２中央部に搬送する。   After the X-ray irradiation is completed, the exit-side shielding door 53 b is opened, and the container vehicle 50 is moved to the exit yard 54. After the container vehicle 50 moves to a predetermined position in the exit yard 54, the second transport cart is stopped and released from the second transport cart, the cart returns to the center of the inspection tunnel 52, and the exit-side shielding door 53b is closed. It is done. During this time, the first transport carriage transports the next vehicle to the central portion of the inspection tunnel 52.

先に、進入ヤード５１で一旦下車した運転手は、専用の通路を通って、退出ヤード５４で待機する。出側遮蔽扉５３ｂが閉まった後、車両５０に再び乗車し、建屋外へと移動する。Ｘ線検査結果が判明するまでは、敷地内駐車場で待機する。１台のコンテナ車両のＸ線照射終了後、中央制御査室で検査官がコンピュータ端末によりＸ線画像データを分析し、不正物品の有無を判断する。以上のサイクルを周期的に繰り返すことで、Ｘ線検査業務が行われる。
特開２００３−２８７５０７号公報 石川島播磨技報，Ｖｏｌ．４３，Ｎｏ．３，ｐ．９２〜９５（２００３−５） The driver who first gets off at the entry yard 51 waits at the exit yard 54 through a dedicated passage. After the exit-side shielding door 53b is closed, the vehicle 50 is boarded again and moved outside the building. Wait until the X-ray inspection result is known at the on-site parking lot. After the X-ray irradiation of one container vehicle is completed, an inspector analyzes X-ray image data using a computer terminal in the central control room, and determines the presence or absence of an illegal article. By repeating the above cycle periodically, X-ray inspection work is performed.
JP 2003-287507 A Ishikawajima Harima Technical Report, Vol. 43, no. 3, p. 92-95 (2003-5)

前記従来例に係るＸ線検査設備は、図９に示した如く、コンテナ車両の進入ヤードから、検査トンネル、退出ヤードに至る検査ラインが一直線状に配置されている。そのため、長手方向に非常に長い敷地が必要になる。即ち、コンテナ車両が、進入ヤードおよび退出ヤードへの進入／退出ゾーンを含むと、敷地の長手方向に必要な長さは１５０〜２００ｍにもなってしまう。   In the X-ray inspection facility according to the conventional example, as shown in FIG. 9, the inspection lines from the entrance yard of the container vehicle to the inspection tunnel and the exit yard are arranged in a straight line. Therefore, a very long site in the longitudinal direction is required. That is, when the container vehicle includes an entry yard and an entry / exit zone to the exit yard, the length required in the longitudinal direction of the site is 150 to 200 m.

また、上述の通り、検査ラインが一直線状に配置されているため、照射されたＸ線の一次反射が飛来し、直接入側遮蔽扉と出側遮蔽扉に当たる。そのため、これらの扉の材質を鉄製とすれば、Ｘ線の遮蔽のため１００ｍｍ程度の厚みを要し、重量的には扉一枚当り３０〜４０トンにもなってしまう。   Further, as described above, since the inspection lines are arranged in a straight line, the primary reflection of the irradiated X-rays comes into direct contact with the entrance-side shielding door and the exit-side shielding door. For this reason, if the material of these doors is made of iron, a thickness of about 100 mm is required for shielding X-rays, and the weight is 30 to 40 tons per door.

一方、本検査設備の標準的な検査能力仕様は、１時間当りコンテナ車両２０台の検査が可能なことが要求されている。このことから、前記遮蔽扉の開閉時間は１０秒前後に納める必要があるが、上述したような重量のため、開閉に必要な駆動モータ容量は数１０ｋＷにもなってしまう。   On the other hand, the standard inspection capability specification of this inspection facility is required to be able to inspect 20 container vehicles per hour. For this reason, it is necessary to set the opening / closing time of the shielding door to about 10 seconds. However, due to the weight as described above, the drive motor capacity required for opening / closing becomes several tens of kW.

更に、図９を用いて説明した通り、コンテナ車両の運転手は、検査前に進入ゾーンで降車した後、検査終了した車両に乗車するため、退出ゾーンまでの長い距離を移動する必要がある。また、進入側と退出側とが遮蔽室を介して離れているため、運転手を監視する監視要員を進入側および退出側の各々に配置する必要がある。   Furthermore, as described with reference to FIG. 9, the driver of the container vehicle needs to travel a long distance to the exit zone in order to get on the vehicle that has finished the inspection after getting off in the entry zone before the inspection. Moreover, since the approach side and the exit side are separated via the shielding room, it is necessary to arrange monitoring personnel for monitoring the driver on each of the entrance side and the exit side.

従って、本発明の目的は、被検査物を入側遮蔽扉と出側遮蔽扉とを有する管理領域内のＸ線検査位置を通過させ、その間に前記被検査物にＸ線を照射し、Ｘ線検査するＸ線検査設備において、長尺の敷地を必要とせず、遮蔽扉が軽量化され、運転手の移動距離も少なくかつ監視要員数も削減できるＸ線検査設備を提供することにある。   Accordingly, an object of the present invention is to pass the inspection object through the X-ray inspection position in the management area having the entrance side shielding door and the exit side shielding door, while irradiating the inspection object with X-rays, An object of the present invention is to provide an X-ray inspection facility that does not require a long site in the X-ray inspection facility for performing a line inspection, the shielding door is lightened, the movement distance of the driver is small, and the number of monitoring personnel can be reduced.

In FIG. 1, the shielding doors 5a and 5b are shown open.

そして、被検査物が前記入側遮蔽扉５ａを介して前記管理領域３内に搬入される搬入方向と、検査終了した前記被検査物が前記出側遮蔽扉５ｂを介して前記管理領域３外に搬出される搬出方向とを形成している。   Then, the carrying-in direction in which the inspection object is carried into the management area 3 through the entry-side shielding door 5a, and the inspection object that has been inspected are outside the management area 3 through the exit-side shielding door 5b. And an unloading direction to be unloaded.

符号７は、前記管理領域３の入側遮蔽扉５ａと出側遮蔽扉５ｂとに隣接して、被検査物を管理領域３に搬入し、検査後に搬出するための搬入出領域を示す。この搬入出領域７には、入側遮蔽扉５ａおよび出側遮蔽扉５ｂに相対して、入側第１移動手段８ａと入側第２移動手段１５ａとからなる入側移動手段、および出側第１移動手段８ｂと出側第２移動手段１５ｂとからなる出側移動手段が、各々入側旋回中心１４ａおよび出側旋回中心１４ｂに向かって配設されている。   Reference numeral 7 denotes a carry-in / out area for carrying an inspection object into the management area 3 and carrying it out after the inspection, adjacent to the entry-side shielding door 5a and the exit-side shielding door 5b of the management area 3. The carry-in / out area 7 includes an entry side moving means including an entry side first moving means 8a and an entry side second moving means 15a, and an exit side relative to the entry side shielding door 5a and the exit side shielding door 5b. Outlet side moving means composed of first moving means 8b and outgoing side second moving means 15b are respectively arranged toward the entrance side turning center 14a and the exit side turning center 14b.

これら入側第１移動手段８ａおよび出側第１移動手段８ｂの上面には、駆動モータ１１ａによって回転駆動される駆動ローラ１２ａが取り付けられている。そして、入側第１移動手段８ａまたは出側第１移動手段８ｂの何れかの駆動ローラ１２ａ，１２ｂ上面に、パレット１０が搭載されている。   A drive roller 12a that is rotationally driven by a drive motor 11a is attached to the upper surfaces of the entry side first movement means 8a and the exit side first movement means 8b. The pallet 10 is mounted on the upper surface of the drive rollers 12a, 12b of either the entry-side first moving means 8a or the exit-side first moving means 8b.

図２は、図１において、入側第１移動手段８ａの駆動ローラ１２ａ上面に、コンテナ車両を積載したパレット１０が搭載された状態のＡ−Ａ断面を示す模式的矢視図である。また、図３は、前記状態において図１のＢ−Ｂ断面を示す矢視図である。   FIG. 2 is a schematic arrow view showing an AA cross section in a state where the pallet 10 loaded with a container vehicle is mounted on the upper surface of the drive roller 12a of the entry side first moving means 8a in FIG. Moreover, FIG. 3 is an arrow view which shows the BB cross section of FIG. 1 in the said state.

図２，３において、未検査のコンテナ２１と、これを搭載した車両２２とからなるコンテナ車両２０を運転手が運転し、図１に示した傾斜板１３ａより登坂し搬入出領域７に進入して、駆動ローラ１２ａ上のパレット１０に積載して停車する。ここで、運転手は下車し、後述する如く待機する。   2 and 3, a driver drives a container vehicle 20 including an uninspected container 21 and a vehicle 22 equipped with the container 21, and climbs up from the inclined plate 13 a shown in FIG. 1 and enters the carry-in / out area 7. Then, the vehicle is loaded on the pallet 10 on the drive roller 12a and stopped. Here, the driver gets off and waits as will be described later.

そして、図１において、パレット１０に積載された未検査の前記コンテナ車両２０は、入側遮蔽扉５ａおよび出側遮蔽扉５ｂの両者が開放された状態で、入側第１移動手段８ａの駆動ローラ１２ａを回転させることにより、入側遮蔽扉５ａを経てパレット１０ごと管理領域３に搬入される。   In FIG. 1, the uninspected container vehicle 20 loaded on the pallet 10 drives the entry side first moving means 8a in a state where both the entry side shield door 5a and the exit side shield door 5b are opened. By rotating the roller 12a, the pallet 10 is carried into the management area 3 through the entrance-side shielding door 5a.

また同一タイミングで、別のパレットに積載され検査終了したコンテナ車両（図示せず）が、後述する出側第２移動手段１５ｂおよび出側第１移動手段８ｂの駆動ローラ１２ｂの回転によって、管理領域３から出側遮蔽扉５ｂを経て搬入出領域７に搬出される。   In addition, a container vehicle (not shown) loaded on another pallet at the same timing and finished inspecting is controlled by the rotation of the driving roller 12b of the outlet side second moving means 15b and the outlet side first moving means 8b described later. 3 is carried out to the carry-in / out area 7 through the exit-side shielding door 5b.

検査終了したコンテナ車両（図示せず）は、図１および図３に示した出側第１移動手段８ｂの駆動ローラ１２ｂによって、パレットごと搬入出領域７に搬出され、後述する如く待機していた運転手が再乗車し、運転して傾斜板１３ｂを降坂し搬入出領域７外に搬出される。   The container vehicle (not shown) that has been inspected is unloaded to the loading / unloading area 7 together with the pallet by the driving roller 12b of the unloading-side first moving means 8b shown in FIGS. The driver re-rides, drives, descends the inclined plate 13b, and is carried out of the carry-in / out area 7.

その後、出側第１移動手段８ｂ上のパレット１０は、トラバーサ２５を上昇させる図示しない昇降機構により、駆動ローラ１２ｂ上から所定高さまで懸架され、トラバーサ２５の走行によって、横断的に入側第１移動手段８ａ上に移送される。入側第１移動手段８ａ上に移送されたパレット１０は、前記トラバーサ２５を昇降機構により下降させ、駆動ローラ１２ａ上に移載される。   Thereafter, the pallet 10 on the exit-side first moving means 8b is suspended from the drive roller 12b to a predetermined height by a lifting mechanism (not shown) that raises the traverser 25, and the entrance-side first side is traversed by the travel of the traverser 25. It is transferred onto the moving means 8a. The pallet 10 transferred onto the entry-side first moving means 8a is moved onto the driving roller 12a by lowering the traverser 25 by an elevating mechanism.

前記トラバーサ２５は、無端チェン２３、スプロケット２４、昇降機構および駆動モータ（図示せず）により構成されている。そして、図３において、スプロケット２４を反時計回りに回転させることによって、チェン２３に懸架された状態で入側第１移動手段８ａ位置まで移動される。   The traverser 25 includes an endless chain 23, a sprocket 24, an elevating mechanism, and a drive motor (not shown). In FIG. 3, the sprocket 24 is rotated counterclockwise to be moved to the position of the entry side first moving means 8 a while being suspended on the chain 23.

このように、前記トラバーサ２５によってコンテナ車両２０を積載するパレット１０を、出側第１移動手段８ｂから入側第１移動手段８ａへ移送することができるので、前記パレット１０の繰り返し使用が可能となり、パレット数を必要最少限に抑えることができるのである。   In this way, the pallet 10 on which the container vehicle 20 is loaded by the traverser 25 can be transferred from the exit-side first moving means 8b to the entry-side first moving means 8a, so that the pallet 10 can be used repeatedly. The number of pallets can be kept to the minimum necessary.

上述したパレット１０の移載方法は、トラバーサ２５に付設された昇降機構により、前記トラバーサ２５を所定高さまで上昇させて出側第１移動手段８ｂ上のパレット１０をトラバーサ２５に懸架し、入側第１移動手段８ａの位置まで移送してトラバーサ２５を所定高さまで下降させ、パレット１０を移載する構成として説明したが、前記移動手段８ａ，８ｂ側に昇降機構を付設することによっても同一の効果が得られる。   In the above-described method of transferring the pallet 10, the traverser 25 is raised to a predetermined height by the lifting mechanism attached to the traverser 25, and the pallet 10 on the exit side first moving means 8 b is suspended on the traverser 25. Although the structure has been described in which the traverser 25 is lowered to a predetermined height by moving to the position of the first moving means 8a and the pallet 10 is transferred, the same structure can be obtained by attaching an elevating mechanism to the moving means 8a and 8b. An effect is obtained.

即ち、付設の昇降機構の下降によって、出側第１移動手段８ｂ上の前記パレット１０をトラバーサ２５へ一旦移し換える。その後、このトラバーサ２５の走行により、このパレット１０を搬送して入側第１移動手段８ａ上へ移動させる。そして、入側第１移動手段８ａの昇降機構により入側第１移動手段８ａを上昇して、前記パレット１０を入側第１移動手段８ａの駆動ローラ１２ａ上に移載するのである。   That is, the pallet 10 on the outlet side first moving means 8b is temporarily transferred to the traverser 25 by lowering the attached lifting mechanism. Thereafter, the traverser 25 travels to convey the pallet 10 and move it onto the entry side first moving means 8a. Then, the entry-side first moving means 8a is raised by the elevating mechanism of the entry-side first moving means 8a, and the pallet 10 is transferred onto the driving roller 12a of the entry-side first moving means 8a.

一方、図１の管理領域３には、入側第１移動手段８ａの配列の延長線上に旋回中心１４ａを有し、前記入側第１移動手段８ａから未検査のコンテナ車両２０が積載されたパレット１０を受け取る入側第２移動手段１５ａが配設されている。同時に、出側第１移動手段８ｂの配列の延長線上に旋回中心１４ｂを有し、後述する中継移動手段から検査の完了したコンテナ車両が積載されたパレット１０を受け取る出側第２移動手段１５ｂが平行状態に配設されている。   On the other hand, the management area 3 in FIG. 1 has a turning center 14a on the extended line of the arrangement of the entry side first moving means 8a, and an uninspected container vehicle 20 is loaded from the entry side first moving means 8a. An entry-side second moving means 15a for receiving the pallet 10 is provided. At the same time, an exit-side second moving means 15b having a turning center 14b on the extended line of the arrangement of the exit-side first moving means 8b and receiving a pallet 10 loaded with a container vehicle that has been inspected from a relay moving means to be described later. They are arranged in parallel.

これらの入側第２移動手段１５ａおよび出側第２移動手段１５ｂの上面には、前述した入側第１移動手段８ａおよび出側第１移動手段８ｂと同一構造の駆動ローラ１２ａ，１２ｂがそれぞれ設置されており、これらの駆動ローラ１２ａ，１２ｂは駆動モータによって回転駆動され、この駆動ローラ１２ａ，１２ｂによりパレット１０の搬送を行っている。   Driving rollers 12a and 12b having the same structure as the above-described entry-side first movement means 8a and exit-side first movement means 8b are respectively provided on the upper surfaces of the entry-side second movement means 15a and the exit-side second movement means 15b. These drive rollers 12a and 12b are rotationally driven by a drive motor, and the pallet 10 is conveyed by the drive rollers 12a and 12b.

そして、前記入側第２移動手段１５ａは、未検査のコンテナ車両２０を積載したパレット１０を受け取るとともに、前記出側第２移動手段１５ｂは、検査終了したコンテナ車両２０を搬入出領域７の出側第１移動手段８ｂへ引き渡した状態にあるとき、これら入側第２移動手段１５ａと出側第２移動手段１５ｂは、各々の旋回中心１４ａ，１４ｂを中心として、後述するＸ線検査位置１８において被検査物移動方向と直線状になる位置まで旋回するのである。   The entry-side second moving means 15a receives the pallet 10 loaded with the uninspected container vehicles 20, and the exit-side second movement means 15b removes the container vehicles 20 that have been inspected from the loading / unloading area 7. When in the state of being handed over to the first side moving means 8b, the second input moving means 15a and the second output moving means 15b are centered on the respective turning centers 14a and 14b, and an X-ray inspection position 18 to be described later. Is turned to a position that is linear with the direction of movement of the inspection object.

即ち、図１の紙面上方向から見て、入側第２移動手段１５ａは旋回中心１４ａを中心として時計回りに、出側第２移動手段１５ｂは旋回中心１４ｂを中心として反時計回りに、後述するＸ線検査位置１８において被検査物移動方向と直線状になる位置まで同時に各々旋回し、入側第２移動手段１５ａと出側第２移動手段１５ｂとが直状の状態に至る。   That is, when viewed from above in FIG. 1, the entry-side second moving means 15a rotates clockwise around the turning center 14a, and the exit-side second moving means 15b turns counterclockwise around the turning center 14b. The X-ray inspection position 18 is simultaneously turned to a position that is linear with the moving direction of the inspection object, and the ingress second moving means 15a and the egress second moving means 15b reach a straight state.

更に、前記入側第２移動手段１５ａと出側第２移動手段１５ｂの各々の旋回中心１４ａ，１４ｂの間のＸ線検査位置１８には、駆動ローラ１２ｃがその上面に配置された中継移動手段１９が設けられており、前記入側第２移動手段１５ａと出側第２移動手段１５ｂとは、上述した旋回終了後は、この中継移動手段１９を挟んで直状の状態になっている。   Further, at the X-ray inspection position 18 between the turning centers 14a and 14b of the entry-side second moving means 15a and the exit-side second moving means 15b, a relay moving means having a driving roller 12c disposed on the upper surface thereof. 19 is provided, and the entrance-side second moving means 15a and the exit-side second moving means 15b are in a straight state with the relay moving means 19 interposed therebetween after the above-described turning is completed.

次に、上述した入側第２移動手段１５ａと出側第２移動手段１５ｂの旋回機構について説明する。前記入側第２移動手段１５ａの旋回機構の一つは、図１に示した通り、この旋回中心１４ａから離れた位置の管理領域３内床面に、前記旋回中心１４ａを中心とする局率半径を持つ軌道１７ａを敷設したことである。   Next, the turning mechanism of the above-mentioned entrance side second moving means 15a and exit side second moving means 15b will be described. As shown in FIG. 1, one of the turning mechanisms of the entry-side second moving means 15a has a locality centered on the turning center 14a on the inner floor surface of the management area 3 at a position away from the turning center 14a. That is, a track 17a having a radius is laid.

図４は、図１の入側第２移動手段１５ａのＣ−Ｃ断面を示す矢視図である。そして、この図４に示すように、前記軌道１７ａ上を、図示しない駆動装置により駆動される車輪１６ａが転動することによって、前記入側第２移動手段１５ａは旋回中心１４ａを中心に旋回移動するのである。   4 is an arrow view showing a CC cross section of the entry-side second moving means 15a in FIG. Then, as shown in FIG. 4, when the wheel 16a driven by a driving device (not shown) rolls on the track 17a, the entry-side second moving means 15a turns around the turning center 14a. To do.

出側第２移動手段１５ｂの旋回機構については、旋回方向が逆方向である点が入側第２移動手段１５ａと相違するのみで、その他の機構は前述の入側第２移動手段１５ａの旋回機構と同一であるので説明を省略する。   The turning mechanism of the exit-side second moving means 15b is different from the entrance-side second moving means 15a only in that the turning direction is opposite, and the other mechanisms are the turning of the entry-side second moving means 15a. Since it is the same as the mechanism, the description is omitted.

そして、前述したように前記入側第２移動手段１５ａと出側第２移動手段１７ｂとが、前記Ｘ線検査位置１８（中継移動手段１９）を挟んで直状の状態になったとき、前記入側第２移動手段１５ａ、中継移動手段１８および出側第２移動手段１５ｂ上に設けられた各々の駆動ローラ１２ａ，１２ｃ，１２ｂの回転駆動によって、コンテナ車両２０が積載されたパレット１０は、入側第２移動手段１５ａから中継移動手段１８を経て出側第２移動手段１５ｂ上へ順次移動される。   As described above, when the entry-side second movement means 15a and the exit-side second movement means 17b are in a straight state with the X-ray inspection position 18 (relay movement means 19) interposed therebetween, The pallet 10 on which the container vehicle 20 is loaded by the rotational driving of the driving rollers 12a, 12c, 12b provided on the entry-side second moving means 15a, the relay moving means 18 and the exit-side second moving means 15b, It is sequentially moved from the entry-side second moving means 15a through the relay moving means 18 onto the exit-side second moving means 15b.

図５は、図１のＤ−Ｄ断面を示す矢視図である。図５においては、入側第２移動手段１５ａおよび出側第２移動手段１５ｂは、上述したような旋回を行う以前の状態を示している。   FIG. 5 is a view taken along the line DD of FIG. In FIG. 5, the entry-side second moving means 15 a and the exit-side second moving means 15 b show a state before the turning as described above.

図中の符号Ｘ2は、垂直Ｘ線照射装置を示し、中継移動手段１８の駆動ローラ１２ｃ上をパレット１０に積載されて移動する、コンテナ車両２０に搭載されたコンテナ２１内を検査するため、垂直方向のＸ線が照射されるように配置されている。そして、垂直Ｘ線検出装置Ｄ2によって、コンテナ２１内を透過した垂直方向のＸ線を検出する構成をなしている。 Reference numeral X 2 in the figure denotes a vertical X-ray irradiation device, and in order to inspect the inside of the container 21 mounted on the container vehicle 20 moving on the pallet 10 on the driving roller 12c of the relay moving means 18, It arrange | positions so that the X-ray of a perpendicular direction may be irradiated. The vertical X-ray detector D 2 detects a vertical X-ray transmitted through the container 21.

同様に、図１に示す通り水平Ｘ線照射装置Ｘ1を、中継移動手段１８の駆動ローラ１２ｃ上をパレット１０に積載されて移動する、コンテナ車両２０に搭載されたコンテナ２１内に向かって、水平方向のＸ線が照射されるように配置されている。そして、水平Ｘ線検出装置Ｄ１によって、コンテナ２１内を透過した水平方向のＸ線を検出する構成としている。 Similarly, as shown in FIG. 1, the horizontal X-ray irradiation device X 1 is moved toward the inside of the container 21 mounted on the container vehicle 20 that moves on the pallet 10 on the driving roller 12 c of the relay moving means 18. It arrange | positions so that the X-ray of a horizontal direction may be irradiated. Then, the horizontal X-ray detector D 1, is configured to detect a horizontal X-rays transmitted through the container 21.

また、図１および図５に示すように、これら水平および垂直Ｘ線照射装置Ｘ1，Ｘ2、水平および垂直Ｘ線検出装置Ｄ１，Ｄ2を囲むように主遮蔽壁４が立体的に構築されて、Ｘ線が外部に漏洩するのを防止している。前記主遮蔽壁４は、水平および垂直Ｘ線照射装置Ｘ1，Ｘ2によって、前記コンテナ２１に向けて照射された水平Ｘ線および垂直Ｘ線が、少なくとも入側遮蔽扉５ａおよび出側遮蔽扉５ｂへの一次反射Ｘ線の飛来を防ぐように構成した。 Further, as shown in FIGS. 1 and 5, the main shielding wall 4 is three-dimensionally so as to surround the horizontal and vertical X-ray irradiation apparatuses X 1 and X 2 and the horizontal and vertical X-ray detection apparatuses D 1 and D 2. Constructed to prevent X-rays from leaking outside. The main shielding wall 4 is configured such that horizontal X-rays and vertical X-rays irradiated toward the container 21 by horizontal and vertical X-ray irradiators X 1 and X 2 are at least the entrance-side shielding door 5a and the exit-side shielding door. It was configured to prevent the primary reflected X-rays from flying to 5b.

即ち、主遮蔽壁４を図１のように構成することによって、少なくとも前記一次反射Ｘ線が飛来しない角度αの範囲に、入側遮蔽扉５ａおよび出側遮蔽扉５ｂを配置したのである。前記主遮蔽壁４は、通常コンクリートや鉄で構成されるが、前記のような構成とすることによって、一次反射Ｘ線が飛来しないので、これらの遮蔽扉両者５ａ，５ｂの厚みを薄くすることができる。   That is, by configuring the main shielding wall 4 as shown in FIG. 1, the entrance-side shielding door 5a and the exit-side shielding door 5b are arranged at least in the range of the angle α where the primary reflected X-ray does not fly. The main shielding wall 4 is usually made of concrete or iron. However, since the primary reflection X-ray does not fly by adopting the above-described structure, the thickness of both the shielding doors 5a and 5b should be reduced. Can do.

また、そのため前記遮蔽扉５ａ，５ｂの重量が軽くなり、これらの開閉を駆動するモータ容量も小さくすることができる。更に、入側および出側の遮蔽扉５ａ，５ｂを近接した構成としたこと、およびこれら遮蔽扉５ａ，５ｂの軽量化により、前記駆動モータの共通化が可能となった。   For this reason, the weight of the shielding doors 5a and 5b is reduced, and the motor capacity for driving the opening and closing of the shielding doors 5a and 5b can be reduced. Furthermore, the drive motor can be shared by adopting a configuration in which the entrance and exit side shielding doors 5a and 5b are close to each other and the weight of the shielding doors 5a and 5b is reduced.

また、このような目的に使用されるＸ線照射装置Ｘ1，Ｘ2には、通常高エネルギー電子線加速器が用いられ、その加速エネルギーは通常９ＭｅＶ（メガエレクトロンボルト）の容量のものが用いられる。更に、Ｘ線検出装置Ｄ１，Ｄ2としては、フォトダイオードの表面にＸ線を光に交換するシンチレータを密着させたものを用いることができる。そして、このＸ線検出装置により検出された透過Ｘ線を電気信号に変換して、画像処理装置（図示せず）に送信する構成としている。 In addition, high-energy electron beam accelerators are usually used for the X-ray irradiation apparatuses X 1 and X 2 used for such purposes, and the acceleration energy is usually 9 MeV (mega electron volt). . Further, as the X-ray detection devices D 1 and D 2 , those in which a scintillator for exchanging X-rays with light is adhered to the surface of the photodiode can be used. The transmission X-ray detected by the X-ray detection device is converted into an electric signal and transmitted to an image processing device (not shown).

更にまた、図１において、パレット１０に積載されて移動しつつ、Ｘ線検査位置１８（中継移動手段１９）でＸ線照射による検査の終了したコンテナ車両２０は、出側第２移動手段１５ｂに移動を完了する。すると、この出側第２移動手段１５ｂは、入側第２移動手段１５ａとともに同時に、両者が平行に配置されていた元の位置（図１の位置）まで、各々の旋回中心１４ｂ，１４ａを中心として旋回する。   Furthermore, in FIG. 1, the container vehicle 20 that has been loaded on the pallet 10 and moved, and has been inspected by X-ray irradiation at the X-ray inspection position 18 (relay moving means 19), is moved to the exit-side second moving means 15b. Complete the move. Then, the exit-side second moving means 15b is centered on the respective turning centers 14b and 14a to the original position (the position in FIG. 1) where both are arranged in parallel with the entrance-side second moving means 15a. Turn as.

上記旋回が完了すると、入側遮蔽扉５ａと出側遮蔽扉５ｂが開き、検査完了した前記コンテナ車両２０は、出側第２移動手段１５ｂの駆動ローラ１２ｂの回転によって、パレットごと搬入出領域７の出側第１移動手段８ｂに引き渡される。同時に、入側第１移動手段８ａ上に待機していた未検査のコンテナ車両２０を積載したパレットが、管理領域３の入側第２移動手段１５ａに引き渡される。   When the turning is completed, the entrance-side shielding door 5a and the exit-side shielding door 5b are opened, and the container vehicle 20 that has been inspected completes the carry-in / out area 7 for each pallet by the rotation of the driving roller 12b of the exit-side second moving means 15b. To the exit side first moving means 8b. At the same time, the pallet loaded with the uninspected container vehicle 20 waiting on the entry-side first moving means 8a is delivered to the entry-side second moving means 15a in the management area 3.

以上のように、Ｘ線検査設備を、搬入方向からＸ線検査位置を経て搬出方向に至る検査全ラインが直線状ではなく往復状の検査ラインとして構成したため、検査建屋の対応する長さは、５０〜６０ｍ程度に短縮することが可能となり、長尺な敷地が不要となった。   As described above, the X-ray inspection equipment is configured as a reciprocal inspection line instead of a straight line from the loading direction to the unloading direction through the X-ray inspection position, so the corresponding length of the inspection building is It became possible to shorten to about 50-60m, and a long site became unnecessary.

また、コンテナ車両の運転手は、未検査のコンテナ車両２０を搬入出領域７の入側第１移動手段８ａのパレット１０上に積載した後、下車して図３に示した待機・監視室２６に入り、検査が終了して搬入出領域７の出側第１移動手段８ｂに引き渡されるまで待機しておく。そして、コンテナ車両２０の検査が終了して出側第１移動手段８ｂまで搬出されて来たとき、この運転手は、検査終了したコンテナ車両２０に再乗車し、運転して傾斜板１３ｂを降坂し搬入出領域７外に退出する。   Further, the driver of the container vehicle loads the uninspected container vehicle 20 on the pallet 10 of the entry side first moving means 8a in the carry-in / out area 7, and then gets off the standby / monitoring room 26 shown in FIG. And wait until the inspection is completed and delivered to the exit-side first moving means 8b in the carry-in / out area 7. Then, when the inspection of the container vehicle 20 is completed and the container vehicle 20 has been carried out to the exit-side first moving means 8b, the driver re-rides the container vehicle 20 that has been inspected and operates to lower the inclined plate 13b. Slope and exit outside the carry-in / out area 7.

このような待機・監視室２６は、図３の通り前記搬入出領域７の入側第１移動手段８ａと出側第１移動手段８ｂとの間で、入側遮蔽扉５ａと出側遮蔽扉５ｂの近傍位置にあって、かつトラバーサ２５によって移載されるパレット１０の障害とならないように、前記トラバーサ２５の上方位置に設置されてなる。即ち、この待機・監視室２６は、床から支持される支柱によって構築するのではなく、図１の紙面の上下方向の梁によって支持するか、または建屋２の天井から吊って構築することが必要である。   As shown in FIG. 3, the standby / monitoring room 26 has an entrance-side shielding door 5a and an exit-side shielding door between the entry-side first movement means 8a and the exit-side first movement means 8b in the carry-in / out area 7. It is installed at a position above the traverser 25 so as not to obstruct the pallet 10 to be transferred by the traverser 25 in the vicinity of 5b. In other words, this standby / monitoring room 26 is not constructed by a column supported from the floor, but is constructed by supporting it by a vertical beam on the paper surface of FIG. 1 or by hanging it from the ceiling of the building 2. It is.

そしてまた、これら運転者を監視する監視要員も、この待機・監視室２６に駐在してその状況を監視することができる。この際、運転者は必ずこの待機・監視室２６にて待機しているので、監視要員は１名で十分対応可能となる。
以上述べたような検査サイクルを繰り返すことによって、時間的なロスなく順次コンテナ２１のＸ線検査を行うことができるのである。 Also, the monitoring personnel who monitor these drivers can be stationed in the standby / monitoring room 26 and monitor the situation. At this time, since the driver always stands by in the standby / monitoring room 26, one monitoring person can sufficiently cope with it.
By repeating the inspection cycle as described above, the X-ray inspection of the containers 21 can be performed sequentially without time loss.

以上、本発明の形態１においては、入側遮蔽扉５ａと出側遮蔽扉５ｂを同時開閉させ、コンテナ車両２０の搭載されたパレット１０の管理領域３への搬入・搬出を同時に行う実施形態を示したが、前者両扉５ａ，５ｂの開閉タイミングは必ずしも同時である必要性はない。   As described above, in Embodiment 1 of the present invention, an embodiment in which the entry-side shielding door 5a and the exit-side shielding door 5b are simultaneously opened and closed, and loading and unloading to the management area 3 of the pallet 10 on which the container vehicle 20 is mounted is performed simultaneously. Although shown, the opening and closing timings of the former doors 5a and 5b are not necessarily the same.

また、入側第２移動手段１５ａが未検査のコンテナ車両２０を積載されたパレット１０を受け取り、出側第２移動手段１５ｂが検査済コンテナ車両２０を積載されたパレット１０を受け取って、前記入側第２移動手段１５ａと出側第２移動手段１５ｂを同時に旋回させる実施形態を示したが、前者両トランスファ１５ａ，１５ｂの旋回は必ずしも同時である必要性はない。   Further, the entry side second moving means 15a receives the pallet 10 loaded with the uninspected container vehicle 20, and the exit side second movement means 15b receives the pallet 10 loaded with the inspected container vehicle 20, Although the embodiment in which the second side moving means 15a and the second outgoing side moving means 15b are swung simultaneously has been described, it is not always necessary for the former transfer bodies 15a and 15b to turn.

更に、前記入側第１移動手段８ａと入側第２移動手段１５ａとで構成される進入ライン、および前記出側第１移動手段８ｂと出側第２移動手段１５ｂとで構成される退出ラインが、前記入側および出側第２移動手段１５ａ，１５ｂが旋回する前の配列では、必ずしも図１に示したように平行状に配列される必要性はなく、設置する敷地の状況に合わせて両ラインは一直線にない任意の方向に構成されて良い。   Furthermore, an entry line composed of the entry side first movement means 8a and the entry side second movement means 15a, and an exit line composed of the exit side first movement means 8b and the exit side second movement means 15b. However, in the arrangement before the entry-side and exit-side second moving means 15a, 15b turn, it is not always necessary to arrange them in parallel as shown in FIG. Both lines may be configured in any direction that is not in a straight line.

更にまた、コンテナ車両２０を検査するためＸ線を照射するＸ線照射装置および透過したＸ線を検出するＸ線検出装置は、水平および垂直の二方向のＸ線照射装置Ｘ1，Ｘ2およびＸ線検出装置Ｄ1，Ｄ2を備えた実施形態で示したが、必ずしも水平および垂直の二方向からの検査が必要ではない。 Furthermore, an X-ray irradiator that irradiates X-rays for inspecting the container vehicle 20 and an X-ray detector that detects transmitted X-rays include horizontal and vertical X-ray irradiators X 1 , X 2 and Although shown in the embodiment provided with the X-ray detection devices D 1 and D 2 , it is not always necessary to inspect from two directions, horizontal and vertical.

即ち、Ｘ線検査位置１８における被検査物移動方向に直角であれば、任意の二方向からのＸ線照射と検出が可能な装置を備えるのでも良い。また更に、場合によっては必ずしも二方向からの検査が必要ではなく、前記被検査物移動方向に直角な任意の一方向からのＸ線照射と検出が可能な装置を備えるのでも良い。   In other words, an apparatus capable of X-ray irradiation and detection from any two directions may be provided as long as it is perpendicular to the object movement direction at the X-ray inspection position 18. Furthermore, in some cases, inspection from two directions is not necessarily required, and an apparatus capable of X-ray irradiation and detection from any one direction perpendicular to the moving direction of the inspection object may be provided.

また、前記コンテナ車両２０の搭載されたパレット１０を搬送する装置として、その上面に駆動ローラを固定した入側および出側第１移動手段８ａ，８ｂ、中継移動手段１８、入側および出側第２移動手段１５ａ，１５ｂを用いたが、これら移動手段の代わりにベルトコンベアやチェンコンベア等のコンベア機能を利用することもできる。また、この場合、パレット１０は必ずしも必須のものではなく、被検査物を直接前記コンベア上に搭載して搬送しても良い。   In addition, as a device for conveying the pallet 10 on which the container vehicle 20 is mounted, first and second entry side moving means 8a and 8b, a relay moving means 18, an entry side and an exit side first having a driving roller fixed on the upper surface thereof. Although the two moving means 15a and 15b are used, a conveyor function such as a belt conveyor or chain conveyor can be used instead of these moving means. In this case, the pallet 10 is not necessarily essential, and the object to be inspected may be directly mounted on the conveyor and conveyed.

更に、本発明の形態１においては、Ｘ線検査位置１８に中継移動手段１９を構成した形態を示したが、前記入側および出側第２移動手段１５ａ，１５ｂ夫々の上端面を、旋回中心１４ａ，１４ｂ上方の適切な長さまで延長することによって、前記入側および出側第２移動手段１５ａ，１５ｂの旋回が完了して、両移動手段１５ａ，１５ｂが前記Ｘ線検査位置１８を挟んで直状の状態になったとき、前記移動手段１５ａ，１５ｂの前記上端面同士が対面する構成をなすことができる。即ち、このような構成とすることによって、前記中継移動手段１９が不要となってくる。   Further, in Embodiment 1 of the present invention, the relay moving means 19 is configured at the X-ray inspection position 18, but the upper end surfaces of the entrance side and exit side second moving means 15a and 15b are set to the turning center. By extending to the appropriate length above 14a, 14b, the turning of the entry side and exit side second movement means 15a, 15b is completed, and both the movement means 15a, 15b sandwich the X-ray inspection position 18 between them. When it becomes a straight state, the said upper end surfaces of the said moving means 15a and 15b can make the structure which faces. That is, with this configuration, the relay moving unit 19 becomes unnecessary.

以上、被検査物にＸ線を照射し、被検査物をＸ線検査する本発明の形態１に係るＸ線検査設備の効果を箇条書きすれば、以下の通りである。
（１）被検査物が搬入出領域から管理領域に搬入される搬入方向と、前記被検査物が前記管理領域外に搬出される搬出方向の両者が、前記被検査物がＸ線検査位置を移動する方向と異なった往復状ラインとなったため、長尺な敷地が不要となった。
（２）主遮蔽壁を、少なくとも入側遮蔽扉および出側遮蔽扉への一次反射Ｘ線の飛来を防ぐ構成としたので、前記遮蔽扉の厚みを薄くすることができる。
（３）また、そのため扉重量が軽くなり、これを駆動するモータ容量も小さくすることができる上、入側および出側の遮蔽扉が近接しているので、駆動モータの共通化を図ることができる。
（４）トラバーサによってコンテナ車両を搭載するパレットを、出側第１移動手段から入側第１移動手段へ戻すことができるので、前記パレットの繰り返し使用が可能となり、パレット数を必要最少限に抑えることができる。
（５）出側第１移動手段と入側第１移動手段との間のトラバーサ上方に、待機・監視室を設けたので、コンテナ車両運転者は、検査開始から検査終了まで移動することなくこの室で待機できる。
（６）更に、監視箇所も１箇所となったので、監視要員は１名で対応可能となった。 As described above, the effects of the X-ray inspection facility according to the first embodiment of the present invention in which the inspection object is irradiated with X-rays and the inspection object is X-ray inspected are as follows.
(1) Both the carry-in direction in which the inspection object is carried into the management area from the carry-in / out area and the carry-out direction in which the inspection object is carried out of the management area indicate that the inspection object has the X-ray inspection position. Since it was a reciprocating line different from the moving direction, a long site became unnecessary.
(2) Since the main shielding wall is configured to prevent the primary reflected X-rays from flying to at least the entry-side shielding door and the exit-side shielding door, the thickness of the shielding door can be reduced.
(3) Further, the door weight is reduced, the motor capacity for driving the door can be reduced, and the entrance and exit side shielding doors are close to each other, so that the drive motor can be shared. it can.
(4) Since the pallet on which the container vehicle is mounted can be returned from the exit-side first moving means to the entry-side first moving means by the traverser, the pallets can be used repeatedly, and the number of pallets is minimized. be able to.
(5) Since the standby / monitoring room is provided above the traverser between the exit-side first moving means and the entry-side first moving means, the container vehicle driver does not move from the start of inspection to the end of inspection. You can wait in the room.
(6) Furthermore, since the number of monitoring points is one, the number of monitoring personnel can be handled by one person.

次に、本発明の形態２に係るＸ線検査設備の全体構成を、その模式的平面図を示した図６を用いて以下に説明する。本発明の形態２が上記形態１と相違するところは、設置する敷地の関係から搬入方向と搬出方向の相対的な配置構成に主たる相違があり、その他はほぼ同構成であるから、上記形態１と同一のものに同一符号を付して、以下その相違点についての説明に止めるものとする。   Next, the whole structure of the X-ray inspection equipment which concerns on Embodiment 2 of this invention is demonstrated below using FIG. 6 which showed the schematic plan view. Form 2 of the present invention differs from Form 1 above in that there is a major difference in the relative arrangement configuration of the carry-in direction and the carry-out direction from the relationship of the site where it is installed, and the rest is substantially the same, so the form 1 The same reference numerals are assigned to the same components as those in FIG.

即ち、図６において、退出ラインを進入ラインに対し並列方向ではなく逆方向に配置したことが前記形態１と大きな相違点である。具体的には、Ｘ線検査位置１８のセンターを中心に、入側第１移動手段８ａと入側第２移動手段１５ａからなる進入ラインを１８０度回転した回転対称の位置に、夫々出側第１移動手段８ｂと出側第２移動手段１５ｂからなる退出ラインを配置したのである。   That is, in FIG. 6, the difference from Embodiment 1 is that the exit lines are arranged in the opposite direction rather than in the parallel direction with respect to the entry line. Specifically, with the center of the X-ray inspection position 18 as the center, the entry side first rotation means 8a and the entry side second movement means 15a are rotated to 180 degrees and rotationally symmetrical positions are respectively provided on the exit side first. The exit line composed of the first moving means 8b and the outgoing second moving means 15b is arranged.

前記に付随して、入側第２移動手段１５ａ用の軌道１７ａが出側第２移動手段１５ｂ用の軌道１７ｂに、また入側の管理領域３ａおよび搬入出領域７ａと付随する建屋が出側の管理領域３ｂおよび搬入出領域７ｂと付随する建屋に、夫々１８０度回転した回転対称の位置に配置されたものである。その他の相違点としては、図６において、トラバーサ２５と待機・監視室２６がないことである。   Along with the above, the track 17a for the entry side second moving means 15a is on the track 17b for the exit side second movement means 15b, and the building associated with the entry side management area 3a and the carry in / out area 7a is on the exit side. The management area 3b and the carry-in / out area 7b are arranged at rotationally symmetrical positions rotated 180 degrees respectively. Another difference is that, in FIG. 6, the traverser 25 and the standby / monitoring room 26 are not provided.

但し、Ｘ線照射装置Ｘ1，Ｘ2およびＸ線検出装置Ｄ1，Ｄ2が設置され主遮蔽壁４に囲まれる領域は、図１と相違点はない。また、図６に示す如く、出側遮蔽扉５ｂは、少なくとも一次反射Ｘ線が飛来しない角度βの範囲内に配置される。 However, the area where the X-ray irradiation apparatuses X 1 and X 2 and the X-ray detection apparatuses D 1 and D 2 are installed and surrounded by the main shielding wall 4 is not different from FIG. Further, as shown in FIG. 6, the exit-side shielding door 5b is disposed within an angle β range where at least primary reflected X-rays do not fly.

従って、本発明の形態２に係るＸ線検査設備の効果を箇条書きすれば、前述した形態１のＸ線検査設備の効果より多少後退するが、以下の通りである。
（１）Ｘ線検査位置に至る搬入方向と搬出方向とが、前記Ｘ線検査位置を中心とする回転対称の検査ラインとなったため、図６のような変形形状を有する敷地に向いている。
（２）主遮蔽壁を、少なくとも入側遮蔽扉および出側遮蔽扉への一次反射Ｘ線の飛来を防ぐ構成としたので、前記遮蔽扉の厚みを薄くすることができる。
（３）また、そのため扉重量が軽くなり、これを駆動するモータ容量も小さくすることができる。 Therefore, if the effects of the X-ray inspection facility according to the second embodiment of the present invention are listed, the effects of the X-ray inspection facility according to the first embodiment are somewhat retreated, but are as follows.
(1) Since the carrying-in direction and the carrying-out direction leading to the X-ray inspection position become a rotationally symmetrical inspection line centering on the X-ray inspection position, it is suitable for a site having a deformed shape as shown in FIG.
(2) Since the main shielding wall is configured to prevent the primary reflected X-rays from flying to at least the entry-side shielding door and the exit-side shielding door, the thickness of the shielding door can be reduced.
(3) For this reason, the door weight is reduced, and the motor capacity for driving the door can be reduced.

次に、本発明の形態３に係るＸ線検査設備の全体構成を、その模式的平面図を示した図７を用いて以下に説明する。本発明の形態３が上記形態１と相違するところは、設置する敷地の関係から搬出方向をＸ線検査位置１８（中継移動手段１９）の被検査物移動方向と同一方向に直線状に固定配置した点に相違があり、その他はほぼ同構成であるから、上記形態１と同一のものに同一符号を付して、以下その相違点についての説明に止めるものとする。   Next, the whole structure of the X-ray inspection equipment which concerns on Embodiment 3 of this invention is demonstrated below using FIG. 7 which showed the schematic plan view. Form 3 of the present invention differs from Form 1 above in that the carry-out direction is fixedly arranged in a straight line in the same direction as the inspected object moving direction at the X-ray inspection position 18 (relay moving means 19) due to the site to be installed. Since the other points are substantially the same in configuration, the same reference numerals are given to the same components as those in the first embodiment, and the description of the differences will be given below.

即ち、図７において、出側第１移動手段８ｂと出側第２移動手段１５ｂからなる前記搬出方向を、Ｘ線検査位置１８（中継移動手段１８）における被検査物移動方向と同一方向に直線状に固定配置した点が前記形態１との大きな相違点である。その結果、出側第２移動手段１５ｂ用の軌道１７ｂが不要となり、トラバーサ２５と待機・監視室２６がないこと、および出側遮蔽扉５ｂが少なくとも一次反射Ｘ線が飛来しない角度αおよびβの範囲外に配置されることが前記形態１と相違する。   That is, in FIG. 7, the carry-out direction composed of the exit-side first moving means 8b and the exit-side second moving means 15b is straight in the same direction as the object movement direction at the X-ray inspection position 18 (relay movement means 18). The point that is fixedly arranged in a shape is a big difference from the first embodiment. As a result, the track 17b for the exit-side second moving means 15b is not required, the traverser 25 and the waiting / monitoring room 26 are not present, and the exit-side shielding door 5b has angles α and β at which primary reflected X-rays do not fly. It differs from the said form 1 to arrange | position outside the range.

従って、本発明の形態３に係るＸ線検査設備の効果を箇条書きすれば、前述した形態１のＸ線検査設備の効果より後退するが、以下の通りである。
（１）搬出方向を、Ｘ線検査位置おける被検査物移動方向と同一方向に直線状に固定配置したため、図７のようなＬ字形状の敷地に向いている。
（２）主遮蔽壁を、少なくとも入側遮蔽扉への一次反射Ｘ線の飛来を防ぐ構成としたので、前記入側遮蔽扉の厚みを薄くすることができる。
（３）また、そのため入側扉重量が軽くなり、これを駆動するモータ容量も小さくすることができる。 Therefore, if the effects of the X-ray inspection facility according to the third embodiment of the present invention are listed, the effects of the X-ray inspection facility according to the first embodiment are set back as follows.
(1) Since the carry-out direction is fixedly arranged linearly in the same direction as the inspected object moving direction at the X-ray inspection position, it is suitable for an L-shaped site as shown in FIG.
(2) Since the main shielding wall is configured to prevent at least the primary reflected X-rays from flying to the entry side shielding door, the thickness of the entry side shielding door can be reduced.
(3) For this reason, the entrance door weight is reduced, and the motor capacity for driving the entrance door can be reduced.

尚、本発明に係る前記形態１乃至３においては、図１，６，７に示したように、何れも被検査物の搬入方向が、Ｘ線検査位置１８（中継移動手段１９）における被検査物移動方向に対して直角または直線状に配置される実施形態を示したが、両者は直角または直線状に配置することを限定するものではなく、Ｘ線検査位置１８における被検査物移動方向に対して任意の角度をなして配置できるものである。   In Embodiments 1 to 3 according to the present invention, as shown in FIGS. 1, 6 and 7, the inspection object is carried in at the X-ray inspection position 18 (relay moving means 19). Although an embodiment in which the object is arranged at right angles or straight lines with respect to the object movement direction has been shown, both are not limited to be arranged at right angles or straight lines, but in the object movement direction at the X-ray inspection position 18. It can be arranged at an arbitrary angle with respect to it.

但し、入側第２移動手段１５ａと出側第２移動手段１５ｂが、Ｘ線検査位置１８（中継移動手段１９）における被検査物移動方向に対して直線状に配置されていない場合は、被検査物が前記Ｘ線検査位置１８に搬入されＸ線検査を受けるときは、少なくとも入側第２移動手段１５ａと出側第２移動手段１５ｂの一方が、Ｘ線検査位置１８における被検査物移動方向と直線状になる位置まで移動する構成とすることが肝要である。前記入側および出側移動手段１５ａおよび１５ｂの移動とは、旋回移動に限定するものではなく、その他の平行移動等任意の移動を含むものである。   However, if the entry-side second moving means 15a and the exit-side second moving means 15b are not arranged linearly with respect to the inspection object movement direction at the X-ray inspection position 18 (relay movement means 19), When an inspection object is carried into the X-ray inspection position 18 and undergoes an X-ray inspection, at least one of the entry-side second moving means 15a and the exit-side second moving means 15b moves the inspection object at the X-ray inspection position 18. It is important to have a configuration that moves to a position that is linear with the direction. The movement of the entry side and exit side moving means 15a and 15b is not limited to the turning movement, but includes any movement such as other parallel movements.
