Description

検査装置および検査システムInspection device and inspection system
　本発明は、検査装置および検査システムに関する。 The present invention relates to an inspection apparatus and an inspection system.
　検査管理データの蓄積要求があった場合に、当該検査管理データを記憶装置に蓄積するデータ記憶手段を備える検査装置が知られている（特許文献１（特開２００８－１８５５４０号公報）参照）。 2. Description of the Related Art There is known an inspection apparatus provided with data storage means for storing inspection management data in a storage device when an inspection management data accumulation request is made (see Japanese Patent Application Laid-Open No. 2008-185540).
　この種の検査装置が新たな検査結果データを記憶部に記憶する場合に、記憶部の空き容量が不足していれば、検査装置は新たな検査結果データを既に記憶されている検査結果データに上書きする。新たな検査結果データが上書きされることによって、既に記憶されている検査結果データの一部が欠落してしまう。 When this type of inspection device stores new inspection result data in the storage unit, if the storage unit has insufficient free space, the inspection device converts the new inspection result data into already stored inspection result data. Overwrite. When new inspection result data is overwritten, a part of the already stored inspection result data is lost.
　本発明の課題は、検査結果に関するデータの欠落を抑制する検査装置および検査システムを提供することである。 An object of the present invention is to provide an inspection apparatus and an inspection system that suppress data loss related to inspection results.
　本発明の第１観点に係る検査装置は、検査部と、データ記憶部と、検査制御部とを備える。検査部は、物品を検査する。データ記憶部は、検査部による検査結果に関するデータを記憶する。検査制御部は、データ記憶部におけるデータの累積容量が予め設定されている停止閾値に到達した場合に、検査部による検査を停止させる。 The inspection apparatus according to the first aspect of the present invention includes an inspection unit, a data storage unit, and an inspection control unit. The inspection unit inspects the article. The data storage unit stores data related to the inspection result by the inspection unit. The inspection control unit stops the inspection by the inspection unit when the accumulated capacity of data in the data storage unit reaches a preset stop threshold.
　本発明の第１観点に係る検査装置では、データの累積容量が予め設定されている停止閾値に到達した場合に、検査制御部が検査部による検査を停止させる。すなわち、空き容量が不足していれば、検査部による検査を停止させるので、検査結果に関するデータは新たに生じない。検査結果に関するデータの一部が欠落する状況を回避することができるので、検査結果に関するデータの欠落を抑制することができる。結果として、検査済みの全ての物品に対してトレーサビリティの実現が期待できる。 In the inspection apparatus according to the first aspect of the present invention, the inspection control unit stops the inspection by the inspection unit when the accumulated capacity of the data reaches a preset stop threshold. That is, if the free space is insufficient, the inspection by the inspection unit is stopped, so that no new data relating to the inspection result is generated. Since it is possible to avoid a situation in which a part of the data related to the inspection result is lost, it is possible to suppress the loss of data related to the inspection result. As a result, traceability can be expected for all inspected items.
　なお、本発明において「検査部による検査を停止させる」には、検査部の動作を停止させることはもちろん、検査部において物品の検査が行われないように、検査部とともに／または単独で、他の機能部の動作を制御することが含まれる。 In the present invention, “to stop the inspection by the inspection unit” not only stops the operation of the inspection unit, but also the inspection unit and / or alone so that the inspection unit is not inspected. The control of the operation of the functional unit of is included.
　例えば、物品を搬送する搬送部によって、検査部へ物品が供給される場合においては、搬送部による物品の供給を停止させることで「検査部による検査を停止させる」ことが可能となる。すなわち、検査部への物品の供給を停止させるように搬送部の動作を制御することは「検査部による検査を停止させる」に相当する。 For example, when the article is supplied to the inspection unit by the conveyance unit that conveys the article, it is possible to “stop the inspection by the inspection unit” by stopping the supply of the article by the conveyance unit. That is, controlling the operation of the transport unit so as to stop the supply of the article to the inspection unit is equivalent to “stopping the inspection by the inspection unit”.
　また、例えば、物品の生産ラインや搬送ラインにおいて、検査部よりも上流側に配置される機能部（例えば、物品の供給を行う物品供給部や、物品の計量を行うための物品計量部等）の動作を停止することで、「検査部による検査を停止させる」ことが可能となる。すなわち、検査部への物品の供給を停止させるように、検査部よりも上流側に配置される機能部の動作を制御することは「検査部による検査を停止させる」に相当する。 In addition, for example, in an article production line or a conveyance line, a function unit (for example, an article supply unit that supplies an article, an article weighing unit that measures an article, or the like) disposed upstream of the inspection unit. By stopping the operation, it is possible to “stop the inspection by the inspection unit”. That is, controlling the operation of the functional unit disposed upstream of the inspection unit so as to stop the supply of the article to the inspection unit corresponds to “stopping the inspection by the inspection unit”.
　また、検査部の検査結果に関するデータの生成に係る動作を停止させることによっても「検査部による検査を停止させる」ことは可能である。例えば、検査部の検査結果が画像処理されることで検査結果に関するデータが生成される場合には、当該画像処理に係る動作を停止させることで「検査部による検査を停止させる」ことが可能となる。すなわち、画像処理等、検査結果に関するデータの生成に係る動作を停止させるように検査部若しくはその他の機能部の動作を制御することは「検査部による検査を停止させる」に相当する。 It is also possible to “stop the inspection by the inspection unit” by stopping the operation related to the generation of data related to the inspection result of the inspection unit. For example, when data related to the inspection result is generated by image processing of the inspection result of the inspection unit, it is possible to “stop the inspection by the inspection unit” by stopping the operation related to the image processing Become. That is, controlling the operation of the inspection unit or other functional units so as to stop the operation related to the generation of data related to the inspection result, such as image processing, corresponds to “stop the inspection by the inspection unit”.
　本発明の第２観点に係る検査装置においては、累積容量が停止閾値よりも小さい第１警告閾値に到達した場合に、検査制御部は、操作者に報知する。 In the inspection apparatus according to the second aspect of the present invention, the inspection control unit notifies the operator when the accumulated capacity reaches the first warning threshold value smaller than the stop threshold value.
　本発明の第２観点に係る検査装置では、検査部による検査が停止される前に、累積容量が第１警告閾値に到達した場合には、検査制御部が操作者に報知するので、検査部による検査が停止される状況を回避することが期待できる。また、操作者への報知によって、操作者によりデータがバックアップされることが期待できる。 In the inspection apparatus according to the second aspect of the present invention, the inspection control unit notifies the operator when the accumulated capacity reaches the first warning threshold before the inspection by the inspection unit is stopped. It can be expected to avoid the situation in which the inspection by is stopped. Moreover, it can be expected that data is backed up by the operator by notifying the operator.
　本発明の第３観点に係る検査装置においては、累積容量が第１警告閾値よりも大きく、かつ停止閾値よりも小さい第２警告閾値に到達した場合に、検査制御部は、操作者に報知する。 In the inspection apparatus according to the third aspect of the present invention, the inspection control unit notifies the operator when the accumulated capacity reaches the second warning threshold value that is larger than the first warning threshold value and smaller than the stop threshold value. .
　本発明の第３観点に係る検査装置では、検査部による検査が停止される前に、累積容量が第２警告閾値に到達した場合には、検査制御部が操作者に再度報知するので、検査部による検査が停止される状況を回避することがより期待できる。また、操作者への報知によって、操作者によりデータがバックアップされることが期待できる。 In the inspection apparatus according to the third aspect of the present invention, the inspection control unit notifies the operator again when the accumulated capacity reaches the second warning threshold before the inspection by the inspection unit is stopped. It can be more expected to avoid the situation where the inspection by the department is stopped. Moreover, it can be expected that data is backed up by the operator by notifying the operator.
　本発明の第４観点に係る検査装置は、ネットワークを介して接続されたバックアップ記憶部と通信する通信部をさらに備える。累積容量が停止閾値に到達した場合に、検査制御部は、通信部を介して、データ記憶部に記憶されているデータをバックアップ記憶部に転送する。 The inspection apparatus according to the fourth aspect of the present invention further includes a communication unit that communicates with a backup storage unit connected via a network. When the accumulated capacity reaches the stop threshold, the inspection control unit transfers the data stored in the data storage unit to the backup storage unit via the communication unit.
　本発明の第４観点に係る検査装置では、累積容量が停止閾値に到達した場合に、データがバックアップ記憶部に転送されるので、データの記憶漏れが抑制される。 In the inspection apparatus according to the fourth aspect of the present invention, when the accumulated capacity reaches the stop threshold, the data is transferred to the backup storage unit, so that data storage leakage is suppressed.
　本発明の第５観点に係る検査装置は、可搬記録媒体であるバックアップ記憶部をさらに備える。累積容量が停止閾値に到達した場合に、検査制御部は、データ記憶部に記憶されているデータをバックアップ記憶部に転送する。 The inspection apparatus according to the fifth aspect of the present invention further includes a backup storage unit that is a portable recording medium. When the accumulated capacity reaches the stop threshold, the inspection control unit transfers the data stored in the data storage unit to the backup storage unit.
　本発明の第５観点に係る検査装置では、累積容量が停止閾値に到達した場合に、データがバックアップ記憶部に転送されるので、データの記憶漏れが抑制される。 In the inspection apparatus according to the fifth aspect of the present invention, when the accumulated capacity reaches the stop threshold, data is transferred to the backup storage unit, so that data storage leakage is suppressed.
　本発明の第６観点に係る検査装置は、操作者による操作入力を受け付ける受付部をさらに備える。検査制御部は、累積容量が停止閾値に到達した場合に、操作入力に基づく検査の実行が可能である実行可能状態から、検査の実行が不可能である実行禁止状態に遷移させる。受付部がデータの削除を指示する操作入力を受け付けた場合に、検査制御部は、データ記憶部に記憶されているデータを削除して、実行禁止状態から実行可能状態に遷移させる。 The inspection apparatus according to the sixth aspect of the present invention further includes a reception unit that receives an operation input by the operator. When the accumulated capacity reaches the stop threshold, the inspection control unit shifts from an executable state in which the inspection based on the operation input can be performed to an execution prohibited state in which the inspection cannot be performed. When the accepting unit accepts an operation input instructing data deletion, the inspection control unit deletes the data stored in the data storage unit, and transitions from the execution prohibited state to the executable state.
　本発明の第６観点に係る検査装置では、検査制御部は、操作者の削除指示を待ってデータを削除するので、バックアップ記憶部へのデータ転送の完了が操作者によって確認された後に、操作者がデータを削除指示することが期待できる。また、検査部による検査が停止された場合に、操作入力に基づく検査の実行が禁止されるので、誤った操作によって検査が続行される状況を回避することができる。 In the inspection apparatus according to the sixth aspect of the present invention, the inspection control unit deletes the data after waiting for the operator's deletion instruction. Therefore, after the operator confirms the completion of the data transfer to the backup storage unit, the operation is performed. Can be expected to instruct the user to delete the data. Further, when the inspection by the inspection unit is stopped, the execution of the inspection based on the operation input is prohibited, so that it is possible to avoid a situation in which the inspection is continued due to an erroneous operation.
　本発明の第７観点に係る検査システムは、検査装置と、管理装置とを備える。管理装置は、検査装置にネットワークを介して接続される。検査装置は、検査部と、検査記憶部と、送信部と、検査制御部とを有する。検査部は、物品を検査する。検査記憶部は、検査部による検査結果に関するデータを記憶する。送信部は、データを管理装置に送信する。検査制御部は、データの累積容量が予め設定されている停止閾値に到達した場合に、検査部による検査を停止させる。管理装置は、受信部と、管理記憶部と、記憶制御部とを有する。受信部は、送信部から送信されるデータを受信する。管理記憶部は、受信部により受信されたデータを記憶する。記憶制御部は、ネットワークが切れた場合に、検査記憶部に記憶されたデータのうち、少なくとも、検査記憶部に記憶されたデータと管理記憶部に記憶されたデータとの差分を取得し、管理記憶部に記憶する。 The inspection system according to the seventh aspect of the present invention includes an inspection device and a management device. The management device is connected to the inspection device via a network. The inspection apparatus includes an inspection unit, an inspection storage unit, a transmission unit, and an inspection control unit. The inspection unit inspects the article.

When the network is disconnected, the storage control unit acquires at least a difference between the data stored in the inspection storage unit and the data stored in the management storage unit among the data stored in the inspection storage unit, and manages the data Store in the storage unit.
　本発明の第７観点に係る検査システムでは、ネットワークが切れた場合には、差分が管理記憶部に記憶されるので、管理記憶部でのデータの欠落を抑制することができる。 In the inspection system according to the seventh aspect of the present invention, when the network is disconnected, the difference is stored in the management storage unit, so that data loss in the management storage unit can be suppressed.
　本発明の第８観点に係る検査システムにおいては、検査制御部は、管理記憶部によるデータの記憶状況を示す情報を記憶制御部から取得し、取得した情報に応じて、検査記憶部に記憶されたデータを削除する。 In the inspection system according to the eighth aspect of the present invention, the inspection control unit acquires information indicating the storage status of data by the management storage unit from the storage control unit, and is stored in the inspection storage unit according to the acquired information.

　本発明の実施形態を以下に示す。なお、以下の実施形態は、具体例に過ぎず、特許請求の範囲に係る発明を限定するものではない。 Embodiments of the present invention are shown below. The following embodiments are merely specific examples and do not limit the invention according to the claims.
　（１）Ｘ線検査装置の全体構成
　図１は、検査装置の一例としてのＸ線検査装置１００の外観斜視図である。図２は、Ｘ線検査装置１００のシールドボックス１１０内の簡易構成図である。 (1) Overall Configuration of X-ray Inspection Apparatus FIG. 1 is an external perspective view of an X-ray inspection apparatus 100 as an example of an inspection apparatus. FIG. 2 is a simplified configuration diagram in the shield box 110 of the X-ray inspection apparatus 100.
　Ｘ線検査装置１００は、例えば、被検査物品である商品Ｇの生産ラインに配置され、商品Ｇ中の異物の有無を検査する。より詳細には、Ｘ線検査装置１００は、連続的に搬送されてくる商品Ｇに対してＸ線を照射して、商品Ｇを透過したＸ線量を基に、商品Ｇに異物が含まれているかを判定する。異物が含まれていると判定された商品Ｇは、Ｘ線検査装置１００の下流側に配置される振分装置によって、不良品として振り分けられる。 The X-ray inspection apparatus 100 is arranged, for example, on a production line for a product G that is an article to be inspected, and inspects the presence or absence of foreign matter in the product G. More specifically, the X-ray inspection apparatus 100 irradiates the product G that is continuously conveyed with X-rays, and based on the X-ray dose transmitted through the product G, the product G contains foreign matter. To determine whether The product G determined to contain foreign matter is sorted as a defective product by the sorting device arranged on the downstream side of the X-ray inspection apparatus 100.
　Ｘ線検査装置１００は、商品Ｇの検査結果に関するデータを逐次蓄積する。データが逐次蓄積され続けると、やがて空き容量が不足する。この場合に、新たなデータが既存のデータに上書きされれば、既存のデータの一部が欠落してしまう。詳しくは後述するが、本実施形態のＸ線検査装置１００は、空き容量が不足していれば、新たな検査を停止することによって、既存のデータの一部が欠落する状況を回避する。 The X-ray inspection apparatus 100 sequentially accumulates data related to the inspection result of the product G. If data is continuously accumulated, the free space will eventually become insufficient. In this case, if new data is overwritten on existing data, a part of the existing data is lost. As will be described in detail later, the X-ray inspection apparatus 100 according to the present embodiment avoids a situation where a part of existing data is lost by stopping a new inspection if the free space is insufficient.
　なお、Ｘ線検査装置１００における「新たな検査を停止する」ことは、Ｘ線検査装置１００において商品Ｇの検査を行う検査部１７６（後述）の動作を停止させること、またはこれとともに／これに代えて、検査部１７６以外の機能部や装置を制御することによって実現される。 Note that “stopping a new inspection” in the X-ray inspection apparatus 100 means that the operation of an inspection unit 176 (described later) that inspects the product G in the X-ray inspection apparatus 100 is stopped, or in conjunction with this. Instead, it is realized by controlling functional units and devices other than the inspection unit 176.
　すなわち、検査部１７６の動作を停止させることで「新たな検査を停止する」ことが可能であるのはもちろんであるが、Ｘ線検査装置１００における商品Ｇの検査が行われないように、Ｘ線検査装置１００に含まれる検査部１７６以外の機能部（例えば、後述するコンベア１２０、Ｘ線照射器１３０、ラインセンサ組立体１４０、または画像生成部１７５等）の動作を制御することによっても「新たな検査を停止する」ことは可能である。 That is, it is possible to “stop the new inspection” by stopping the operation of the inspection unit 176, but the X-ray inspection apparatus 100 does not inspect the product G so that X is not inspected. It is also possible to control the operation of functional units other than the inspection unit 176 included in the line inspection apparatus 100 (for example, a conveyor 120, an X-ray irradiator 130, a line sensor assembly 140, or an image generation unit 175 described later). It is possible to “stop a new examination”.
　また、Ｘ線検査装置１００における商品Ｇの検査が行われないように、生産ラインに配置されるＸ線検査装置１００以外の装置（例えば、Ｘ線検査装置１００よりも上流側に配置される、商品Ｇの供給を行うための商品供給装置、商品Ｇの計量を行うための計量装置、または商品Ｇを搬送するための搬送装置等）の動作を制御することによっても「新たな検査を停止する」ことは可能である。 In addition, an apparatus other than the X-ray inspection apparatus 100 disposed on the production line (for example, disposed upstream of the X-ray inspection apparatus 100 so that the product G is not inspected by the X-ray inspection apparatus 100. The “new inspection is stopped” also by controlling the operation of the product supply device for supplying the product G, the weighing device for weighing the product G, the transport device for transporting the product G, etc. It is possible.
　Ｘ線検査装置１００は、主として、シールドボックス１１０、コンベア１２０、Ｘ線照射器１３０、ラインセンサ組立体１４０、および表示部１５０を含んで構成される。図１および図２に示されるＸ軸方向は、商品Ｇの搬送方向である左右方向を示し、Ｙ軸方向は、ラインセンサ組立体１４０の長手方向である前後方向を示し、Ｚ軸方向は、ラインセンサ組立体１４０の高さ方向である上下方向を示す。なお、「前」を「正面」と記す場合がある。また、図２のハッチング領域ＸＲは、Ｘ線が照射される領域を示す。 The X-ray inspection apparatus 100 mainly includes a shield box 110, a conveyor 120, an X-ray irradiator 130, a line sensor assembly 140, and a display unit 150. The X-axis direction shown in FIGS. 1 and 2 indicates the left-right direction that is the conveyance direction of the product G, the Y-axis direction indicates the front-rear direction that is the longitudinal direction of the line sensor assembly 140, and the Z-axis direction is The vertical direction which is the height direction of the line sensor assembly 140 is shown. Note that “front” may be referred to as “front”. A hatched area XR in FIG. 2 indicates an area irradiated with X-rays.

　シールドボックス１１０は、コンベア１２０の一部、Ｘ線照射器１３０、およびラインセンサ組立体１４０等を収容する。シールドボックス１１０は、両側面に開口部１１１を有する。開口部１１１は、商品Ｇの搬入出口である。 (2) Detailed configuration of X-ray inspection apparatus (2-1) Shield box The shield box 110 accommodates a part of the conveyor 120, the X-ray irradiator 130, the line sensor assembly 140, and the like. The shield box 110 has openings 111 on both side surfaces. The opening 111 is a carry-in / out port for the product G.
　開口部１１１は、遮蔽ノレン１６０によって塞がれる。遮蔽ノレン１６０は、シールドボックス１１０の外部へのＸ線漏洩を抑える。遮蔽ノレン１６０は、鉛を含むゴムから成形される。商品Ｇが搬入出される場合に、遮蔽ノレン１６０は、商品Ｇにより押しのけられる。 The opening 111 is blocked by the shielding nolen 160. The shield nolen 160 suppresses X-ray leakage to the outside of the shield box 110. The shielding nolen 160 is formed from rubber containing lead. When the product G is carried in and out, the shielding nolen 160 is pushed away by the product G.
　（２－２）コンベア
　コンベア１２０は、シールドボックス１１０内において商品Ｇを搬送する。コンベア１２０は、コンベアモータ１２１（図３参照）により駆動する。 (2-2) Conveyor The conveyor 120 conveys the product G in the shield box 110. The conveyor 120 is driven by a conveyor motor 121 (see FIG. 3).
　（２－３）Ｘ線照射器
　Ｘ線照射器１３０は、コンベア１２０の中央部の上方に配置される。Ｘ線照射器１３０は、下方のラインセンサ組立体１４０に向けてＸ線を照射する。すなわち、Ｘ線照射器１３０は、下方のコンベア１２０により搬送される商品ＧにＸ線を照射する。 (2-3) X-ray irradiator The X-ray irradiator 130 is disposed above the central portion of the conveyor 120. The X-ray irradiator 130 irradiates the lower line sensor assembly 140 with X-rays. That is, the X-ray irradiator 130 irradiates the product G conveyed by the lower conveyor 120 with X-rays.
　（２－４）ラインセンサ組立体
　ラインセンサ組立体１４０は、コンベア１２０の下方に配置される。ラインセンサ組立体１４０は、商品Ｇおよびコンベア１２０を透過するＸ線を検出する。ラインセンサ組立体１４０は、検出結果に応じた検出信号を生成して、後述する制御部１７０（図３参照）に送信する。 (2-4) Line Sensor Assembly The line sensor assembly 140 is disposed below the conveyor 120. The line sensor assembly 140 detects X-rays that pass through the commodity G and the conveyor 120. The line sensor assembly 140 generates a detection signal corresponding to the detection result, and transmits the detection signal to the control unit 170 (see FIG. 3) described later.
　（２－５）表示部
　表示部１５０は、シールドボックス１１０の正面上部に配置される。表示部１５０は、タッチパネル機能付きのＬＣＤモニタである。表示部１５０は、Ｘ線検査装置１００に関する情報を表示する。より詳細には、各種設定に関するメニュー画面、各種の操作画面、警告画面、エラー画面、後述のＨＤＤ１７４（図３参照）に記憶されているデータを削除するための画面等を表示する。また、表示部１５０は、操作者による操作入力を受け付ける受付部としても機能する。例えば、表示部１５０は、Ｘ線検査装置１００を操作する操作者を示す情報（例えば、操作者の氏名）を受け付ける。Ｘ線検査装置１００による検査の前に、操作者を示す情報に対応付けられた、後述の識別番号が予め設定されることにより、Ｘ線検査装置１００は、識別番号を検査結果に対応付けて記憶することができる。 (2-5) Display Unit The display unit 150 is disposed on the upper front portion of the shield box 110. The display unit 150 is an LCD monitor with a touch panel function. The display unit 150 displays information regarding the X-ray inspection apparatus 100. More specifically, a menu screen regarding various settings, various operation screens, a warning screen, an error screen, a screen for deleting data stored in the HDD 174 (see FIG. 3), which will be described later, and the like are displayed. The display unit 150 also functions as a reception unit that receives an operation input by the operator. For example, the display unit 150 receives information (for example, the name of the operator) indicating the operator who operates the X-ray inspection apparatus 100. Prior to the inspection by the X-ray inspection apparatus 100, an identification number (to be described later) associated with information indicating the operator is set in advance, so that the X-ray inspection apparatus 100 associates the identification number with the inspection result. Can be remembered.
　（３）Ｘ線検査装置のブロック図
　図３は、Ｘ線検査装置１００のブロック図である。Ｘ線検査装置１００は、制御部１７０、通信部１８１、可搬記録媒体であるバックアップ記憶部の一例としてのＵＳＢメモリ１８２、および計時部１９０をさらに備える。 (3) Block diagram of X-ray inspection apparatus FIG. 3 is a block diagram of the X-ray inspection apparatus 100. The X-ray inspection apparatus 100 further includes a control unit 170, a communication unit 181, a USB memory 182 as an example of a backup storage unit that is a portable recording medium, and a timer unit 190.
　制御部１７０は、コンベアモータ１２１、Ｘ線照射器１３０、ラインセンサ組立体１４０、表示部１５０、通信部１８１、ＵＳＢメモリ１８２、および計時部１９０に接続される。制御部１７０は、ＣＰＵ１７１、ＲＯＭ１７２、ＲＡＭ１７３およびデータ記憶部の一例としてのＨＤＤ１７４等から構成されるコンピュータである。ＣＰＵ１７１、ＲＯＭ１７２、ＲＡＭ１７３、およびＨＤＤ１７４は、アドレスバスおよびデータバス等のバスラインを介して相互に接続される。ＨＤＤ１７４には、検査結果に関するデータが蓄積される。 The control unit 170 is connected to the conveyor motor 121, the X-ray irradiator 130, the line sensor assembly 140, the display unit 150, the communication unit 181, the USB memory 182, and the time measuring unit 190. The control unit 170 is a computer including a CPU 171, a ROM 172, a RAM 173, an HDD 174 as an example of a data storage unit, and the like. The CPU 171, the ROM 172, the RAM 173, and the HDD 174 are connected to each other via bus lines such as an address bus and a data bus. The HDD 174 stores data related to the inspection result.
　ＣＰＵ１７１がＲＯＭ１７２に記憶されている制御プログラムを実行することによって、ＣＰＵ１７１は、画像生成部１７５、検査部１７６、データ書込部１７７、検査制御部１７８といった機能部としての役割を果たす。 When the CPU 171 executes the control program stored in the ROM 172, the CPU 171 serves as a functional unit such as an image generation unit 175, an inspection unit 176, a data writing unit 177, and an inspection control unit 178.
　画像生成部１７５は、商品ＧがＸ線照射領域を通過するときに、ラインセンサ組立体１４０から送信される検出信号を細かい時間間隔で取得する。そして、取得した検出信号を基に、商品ＧのＸ線画像を生成する。 The image generation unit 175 acquires the detection signal transmitted from the line sensor assembly 140 at fine time intervals when the product G passes through the X-ray irradiation region. And the X-ray image of the goods G is produced | generated based on the acquired detection signal.
　検査部１７６は、商品Ｇへの異物混入の有無をＸ線画像から判断する。検査部１７６は、例えば、被検出物の大まかな厚さに沿って基準レベルを設定し、像が基準レベルよりも暗くなった場合に、商品Ｇ内に異物が混入していると判断する。 The inspection unit 176 determines the presence or absence of foreign matter in the product G from the X-ray image. For example, the inspection unit 176 sets a reference level along the rough thickness of the object to be detected, and determines that foreign matter is mixed in the product G when the image becomes darker than the reference level.
　データ書込部１７７は、検査結果に関するデータをＨＤＤ１７４に逐次書き込む。検査結果に関するデータの詳細は後述する。データ書込部１７７は、予め設定されているファイルフォーマットに従って、画像生成部１７５により生成されたＸ線画像のデータをファイル化する。また、データ書込部１７７は、検出信号を基に、検査対象の商品Ｇと直近の商品Ｇとのピッチを算出する。 The data writing unit 177 sequentially writes data related to the inspection result to the HDD 174. Details of the data relating to the inspection result will be described later. The data writing unit 177 converts the X-ray image data generated by the image generation unit 175 into a file according to a preset file format. The data writing unit 177 calculates the pitch between the product G to be inspected and the latest product G based on the detection signal.
　検査制御部１７８は、ＨＤＤ１７４におけるデータの累積容量を監視して、累積容量に応じて、検査部１７６を制御する。検査制御部１７８は、累積容量に応じて、警告画面、エラー画面等を表示部１５０に表示する。 The inspection control unit 178 monitors the accumulated capacity of data in the HDD 174 and controls the inspecting unit 176 according to the accumulated capacity. The inspection control unit 178 displays a warning screen, an error screen, and the like on the display unit 150 according to the accumulated capacity.
　通信部１８１は、ネットワークを介して接続されたバックアップ記憶部の一例としてのサーバ装置と通信する。 The communication unit 181 communicates with a server device as an example of a backup storage unit connected via a network.
　計時部１９０は、日時を計る。計時部１９０は、日時を示す日時情報をデータ書込部１７７に送信する。 Time measuring unit 190 measures the date and time. The timer unit 190 transmits date / time information indicating the date / time to the data writing unit 177.
　（４）検査結果に関するデータ
　図４は、検査結果に関するデータを説明する図である。検査結果に関するデータは、項目として、異物の有無、排出方向、日時、識別番号、ピッチ、および画像ファイルを含む。図４の例では、検査結果に関するデータとして２つのデータが示される。 (4) Data on Inspection Results FIG. 4 is a diagram for explaining data on inspection results. The data related to the inspection result includes the presence / absence of a foreign substance, the discharge direction, the date / time, the identification number, the pitch, and an image file as items. In the example of FIG. 4, two data are shown as data related to the inspection result.
　「異物の有無」の項目は、商品Ｇ中の異物の有無を示す。「異物の有無」の項目には、異物が検出されなければ、「無」が記述され、異物が検出されれば、「有」が記述される。 The item “existence of foreign matter” indicates the presence or absence of foreign matter in the product G. In the item “existence of foreign matter”, “no” is described if no foreign matter is detected, and “present” is described if a foreign matter is detected.
　「排出方向」の項目は、商品Ｇの排出方向を示す。一般的に、異物が検出されなければ、商品Ｇは搬送方向に沿って排出され、異物が検出されれば、商品Ｇは搬送方向に交差する方向である前後方向のいずれか（例えば搬送方向に対して右側）に排出される。本実施形態においては、「排出方向」の項目には、異物が検出されなければ、「真っすぐ」が記述され、異物が検出されれば、「右」が記述される。 The item “Discharge direction” indicates the discharge direction of the product G. In general, if no foreign matter is detected, the product G is discharged along the transport direction, and if a foreign matter is detected, the product G is one of the front and rear directions that intersect the transport direction (for example, in the transport direction). On the right side). In the present embodiment, the item “discharge direction” describes “straight” if no foreign matter is detected, and “right” if a foreign matter is detected.
　「日時」の項目には、検査が実行されたときの日時が記述される。 In the “Date” item, the date and time when the inspection was executed is described.
　「識別番号」の項目は、操作者を示す情報に対応付けられた識別番号を示す。操作者は、識別番号によって識別される。既に説明したように、Ｘ線検査装置１００による検査の前に、識別情報が操作者によって予め設定される。したがって、「識別番号」の項目には、設定済みの識別番号が記述される。 The item of “identification number” indicates an identification number associated with information indicating the operator. The operator is identified by an identification number. As already described, the identification information is preset by the operator before the inspection by the X-ray inspection apparatus 100. Therefore, a set identification number is described in the item “identification number”.
　「ピッチ」の項目には、現在の検査対象の商品Ｇと直近の商品Ｇとの距離が記述される。なお、ピッチにばらつきがある場合には、Ｘ線検査装置１００は、Ｘ線検査装置１００の上流側に配置される商品供給装置を制御することによって、等間隔になるようにピッチを調整してもよい。なお、「ピッチ」の項目には、直近の商品Ｇとの時間間隔が記述されてもよい。 The item “Pitch” describes the distance between the current product G to be inspected and the latest product G. If the pitch varies, the X-ray inspection apparatus 100 adjusts the pitch so that the pitches are evenly spaced by controlling a product supply apparatus arranged upstream of the X-ray inspection apparatus 100. Also good. In the “pitch” item, a time interval with the latest product G may be described.
　「画像ファイル」の項目には、画像生成部１７５により生成されたＸ線画像のファイル名が記述される。 In the “image file” item, the file name of the X-ray image generated by the image generation unit 175 is described.
　（５）監視処理を示すフローチャート
　図５は、検査制御部１７８による監視処理を示すフローチャートである。本フローチャートは、検査結果に関するデータがＨＤＤ１７４に記憶される度に実行される。本フローチャートにおいて、変数ｄｃａｐは、ＨＤＤ１７４に記憶されているデータの累積容量を示す。定数Ｔｈｓは、検査の停止の判定に用いられる停止閾値を示す。定数Ｔｈｗ1は、一段階目の警告の判定に用いられる第１警告閾値を示す。定数Ｔｈｗ2は、二段階目の警告の判定に用いられる第２警告閾値を示す。定数Ｔｈｓ、定数Ｔｈｗ1、および定数Ｔｈｗ2は、Ｔｈｓ＞Ｔｈｗ2＞Ｔｈｗ1の関係を満たす。 (5) Flowchart showing Monitoring Processing FIG. 5 is a flowchart showing monitoring processing by the inspection control unit 178. This flowchart is executed every time data related to the inspection result is stored in the HDD 174. In this flowchart, a variable dcap indicates the accumulated capacity of data stored in the HDD 174. The constant Ths indicates a stop threshold value used for determining whether to stop the inspection. The constant Thw 1 indicates a first warning threshold value used for determination of the first-stage warning. The constant Thw 2 indicates the second warning threshold value used for the determination of the second-stage warning. The constant Ths, the constant Thw 1 , and the constant Thw 2 satisfy the relationship Ths> Thw 2 > Thw 1 .
　検査結果に関するデータがＨＤＤ１７４に記憶されると、検査制御部１７８は、変数ｄｃａｐに応じた制御を行う。具体的には、まず、検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｓ以上であるか判定する（ステップＳ１０１）。検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｓ以上であると判定する場合には（ステップＳ１０１でＹＥＳ）、ＨＤＤ１７４の空き容量が不足しているとみなし、検査部１７６による検査を停止する（ステップＳ１０２）。検査が停止されることによって、検査結果に関するデータは新たに生じないので、検査結果に関するデータの一部が欠落する状況を回避することができる。検査制御部１７８は、ＨＤＤ１７４に記憶されているデータをバックアップする（ステップＳ１０３）。具体的には、検査制御部１７８は、通信部１８１を介して、ＨＤＤ１７４に記憶されているデータをサーバ装置に転送する。検査制御部１７８は、ＨＤＤ１７４に記憶されているデータをＵＳＢメモリ１８２に転送してもよい。 When the data related to the inspection result is stored in the HDD 174, the inspection control unit 178 performs control according to the variable dcap. Specifically, first, the inspection control unit 178 determines whether the variable dcap is greater than or equal to the constant Ths (step S101). If the inspection control unit 178 determines that the variable dcap is equal to or greater than the constant Ths (YES in step S101), the inspection control unit 178 considers that the HDD 174 has insufficient free space and stops the inspection by the inspection unit 176 (step S102). ). When the inspection is stopped, no new data related to the inspection result is generated, so that a situation where a part of the data related to the inspection result is missing can be avoided. The inspection control unit 178 backs up the data stored in the HDD 174 (step S103). Specifically, the inspection control unit 178 transfers data stored in the HDD 174 to the server device via the communication unit 181. The inspection control unit 178 may transfer the data stored in the HDD 174 to the USB memory 182.
　ここで、「検査部１７６による検査を停止」させるには、検査部１７６の動作を停止させることはもちろん、検査部１７６において商品Ｇの検査が行われないように、検査部１７６とともに／または単独で他の機能部（具体的にはコンベア１２０、Ｘ線照射器１３０、ラインセンサ組立体１４０、または画像生成部１７５等）の動作を制御することが含まれる。 Here, in order to “stop the inspection by the inspection unit 176”, not only the operation of the inspection unit 176 but also the inspection unit 176 and / or the single unit so that the inspection of the product G is not performed. This includes controlling the operation of other functional units (specifically, the conveyor 120, the X-ray irradiator 130, the line sensor assembly 140, the image generation unit 175, etc.).
　例えば、コンベア１２０の動作を停止させることにより商品Ｇの供給を停止することで、「検査部１７６による検査を停止」させることは可能である。また、例えば、Ｘ線照射器１３０やラインセンサ組立体１４０の動作を停止させることによっても「検査部１７６による検査を停止」させることは可能である。また、例えば、画像生成部１７５の動作を停止させることによっても「検査部１７６による検査を停止」させることは可能である。すなわち、検査部１７６への商品Ｇの供給を停止させるようにこれらの機能部の動作を制御することは「検査部１７６による検査を停止させる」ことに相当する。 For example, it is possible to “stop the inspection by the inspection unit 176” by stopping the supply of the product G by stopping the operation of the conveyor 120. Further, for example, it is possible to “stop the inspection by the inspection unit 176” by stopping the operations of the X-ray irradiator 130 and the line sensor assembly 140. Further, for example, it is possible to “stop the inspection by the inspection unit 176” by stopping the operation of the image generation unit 175. That is, controlling the operation of these functional units so as to stop the supply of the commodity G to the inspection unit 176 corresponds to “stopping the inspection by the inspection unit 176”.
　また、例えば、検査部１７６における検査結果に関するデータの生成を担う画像生成部１７５の動作を停止させることについても、「検査部１７６による検査を停止させる」ことと同義である。 Also, for example, stopping the operation of the image generation unit 175 responsible for generating data related to the inspection result in the inspection unit 176 is synonymous with “stopping the inspection by the inspection unit 176”.
　また、例えば、Ｘ線検査装置１００における商品Ｇの検査が行われないように、生産ラインに配置されるＸ線検査装置１００以外の装置（例えば、Ｘ線検査装置１００よりも上流側に配置される、商品Ｇの供給を行うための商品供給装置、商品Ｇの計量を行うための計量装置、または商品Ｇを搬送するための搬送装置等）の動作を制御することについても、「検査部１７６による検査を停止させる」ことと同義である。なお、係る態様により、「検査部１７６による検査を停止させる」場合には、生産ラインに配置される各装置のうち商品Ｇの流れ方向上流側に位置する装置を先に停止させ、Ｘ線検査装置１００においては商品Ｇが供給されなくなった時点で所定の機能部を停止させるように構成することで、商品Ｇのロスを抑制することが可能となる。 Further, for example, an apparatus other than the X-ray inspection apparatus 100 disposed on the production line (for example, disposed upstream of the X-ray inspection apparatus 100 so that the product G is not inspected by the X-ray inspection apparatus 100). The control of the operation of the product supply device for supplying the product G, the weighing device for weighing the product G, the transport device for transporting the product G, etc. It is synonymous with “stop the inspection by”. In addition, according to the aspect, in the case of “stopping the inspection by the inspection unit 176”, among the devices arranged on the production line, the device located upstream in the flow direction of the product G is stopped first, and the X-ray inspection is performed. The apparatus 100 is configured to stop the predetermined functional unit when the product G is no longer supplied, so that loss of the product G can be suppressed.
　検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｓ未満であると判定する場合には（ステップＳ１０１でＮＯ）、続いて、変数ｄｃａｐが定数Ｔｈｗ2以上であるか判定する（ステップＳ１０４）。検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｗ2以上であると判定する場合には（ステップＳ１０４でＹＥＳ）、ＨＤＤ１７４の空き容量がまもなく不足するとみなし、その旨を操作者に報知する（ステップＳ１０５）。例えば、検査制御部１７８は、累積容量が定数Ｔｈｗ2に達した旨を示す警告画面を表示部１５０に表示する。なお、ＨＤＤ１７４の空き容量がまもなく不足する旨を示す警告画面を表示しても良いし、ＨＤＤ１７４に記憶されたデータのバックアップを操作者に促す画面を表示してもよい。 If the inspection control unit 178 determines that the variable dcap is less than the constant Ths (NO in step S101), it subsequently determines whether the variable dcap is equal to or greater than the constant Thw 2 (step S104). If the inspection control unit 178 determines that the variable dcap is equal to or greater than the constant Thw 2 (YES in step S104), the inspection control unit 178 considers that the free space of the HDD 174 will soon be insufficient, and notifies the operator accordingly (step S105). . For example, the inspection control unit 178 displays a warning screen indicating that the accumulated capacity has reached the constant Thw 2 on the display unit 150. A warning screen indicating that the free space of HDD 174 will soon be insufficient may be displayed, or a screen prompting the operator to back up data stored in HDD 174 may be displayed.
　検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｗ2未満であると判定する場合には（ステップＳ１０４でＮＯ）、続いて、変数ｄｃａｐが定数Ｔｈｗ1以上であるか判定する（ステップＳ１０６）。検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｗ1以上であると判定する場合には（ステップＳ１０６でＹＥＳ）、その旨を操作者に報知する（ステップＳ１０７）。例えば、検査制御部１７８は、累積容量が定数Ｔｈｗ1に達した旨を示す警告画面を表示部１５０に表示する。ＨＤＤ１７４に記憶されたデータのバックアップを操作者に促す画面を表示してもよい。 When determining that the variable dcap is less than the constant Thw 2 (NO in step S104), the inspection control unit 178 subsequently determines whether the variable dcap is greater than or equal to the constant Thw 1 (step S106). If the inspection control unit 178 determines that the variable dcap is greater than or equal to the constant Thw 1 (YES in step S106), the inspection control unit 178 notifies the operator of that fact (step S107). For example, the inspection control unit 178 displays a warning screen indicating that the accumulated capacity has reached the constant Thw 1 on the display unit 150. A screen that prompts the operator to back up data stored in the HDD 174 may be displayed.
　検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｗ1未満であると判定する場合（ステップＳ１０６でＮＯ）、ステップＳ１０３、ステップ１０５、またはステップＳ１０７の処理が実行された場合には、一連の処理を終了する。 When determining that the variable dcap is less than the constant Thw 1 (NO in step S106), the inspection control unit 178 ends the series of processes when the process of step S103, step 105, or step S107 is executed. To do.
　（６）特徴
　上記の実施形態のＸ線検査装置１００は、検査部１７６と、ＨＤＤ１７４と、検査制御部１７８とを備える。検査部１７６は、商品Ｇを検査する。ＨＤＤ１７４は、検査部１７６による検査結果に関するデータを記憶する。検査制御部１７８は、ＨＤＤ１７４におけるデータの累積容量を示す変数ｄｃａｐが予め設定されている停止閾値を示す定数Ｔｈｓに到達した場合に、検査部１７６による検査を停止させる。 (6) Features The X-ray inspection apparatus 100 of the above embodiment includes an inspection unit 176, an HDD 174, and an inspection control unit 178. The inspection unit 176 inspects the product G. The HDD 174 stores data related to the inspection result by the inspection unit 176. The inspection control unit 178 stops the inspection by the inspection unit 176 when the variable dcap indicating the accumulated capacity of data in the HDD 174 reaches a constant Ths indicating a preset stop threshold.
　上記の実施形態のＸ線検査装置１００においては、変数ｄｃａｐが定数Ｔｈｓに到達した場合に、検査制御部１７８が検査部１７６による検査を停止させる。すなわち、空き容量が不足していれば、検査部１７６による検査を停止させるので、検査結果に関するデータは新たに生じない。検査結果に関するデータの一部が欠落する状況を回避することができるので、検査結果に関するデータの欠落を抑制することができる。結果として、検査済みの全ての商品Ｇに対してトレーサビリティの実現が期待できる。 In the X-ray inspection apparatus 100 of the above embodiment, when the variable dcap reaches the constant Ths, the inspection control unit 178 stops the inspection by the inspection unit 176. That is, if the free space is insufficient, the inspection by the inspection unit 176 is stopped, so that no new data regarding the inspection result is generated. Since it is possible to avoid a situation in which a part of the data related to the inspection result is lost, it is possible to suppress the loss of data related to the inspection result. As a result, it is possible to expect traceability for all the inspected products G.
　上記の実施形態のＸ線検査装置１００においては、変数ｄｃａｐが第１警告閾値を示す定数Ｔｈｗ1に到達した場合に、検査制御部１７８は、表示部１５０に警告画面等を表示することによって、操作者に報知する。定数Ｔｈｗ1は、定数Ｔｈｓよりも小さい。 In the X-ray inspection apparatus 100 of the above embodiment, when the variable dcap reaches the constant Thw 1 indicating the first warning threshold, the inspection control unit 178 displays a warning screen or the like on the display unit 150, Notify the operator. The constant Thw 1 is smaller than the constant Ths.
　検査部１７６による検査が停止される前に、変数ｄｃａｐが定数Ｔｈｗ1に到達した場合には、検査制御部１７８が操作者に報知するので、検査部１７６による検査が停止される状況を回避することが期待できる。また、操作者への報知によって、データのバックアップが必要であることを操作者に理解させ、操作者によりデータがバックアップされることが期待できる。 If the variable dcap reaches the constant Thw 1 before the inspection by the inspection unit 176 is stopped, the inspection control unit 178 notifies the operator, so that the situation where the inspection by the inspection unit 176 is stopped is avoided. I can expect that. In addition, by notifying the operator, the operator can understand that data backup is necessary, and it can be expected that the operator backs up the data.
　上記の実施形態のＸ線検査装置１００においては、変数ｄｃａｐが第２警告閾値を示す定数Ｔｈｗ2に到達した場合に、検査制御部１７８は、操作者に報知する。定数Ｔｈｗ2は、定数Ｔｈｗ1よりも大きく、かつ定数Ｔｈｓよりも小さい。 In the X-ray inspection apparatus 100 of the above embodiment, when the variable dcap reaches the constant Thw 2 indicating the second warning threshold, the inspection control unit 178 notifies the operator. The constant Thw 2 is larger than the constant Thw 1 and smaller than the constant Ths.
　検査部１７６による検査が停止される前に、変数ｄｃａｐが定数Ｔｈｗ2に到達した場合には、検査制御部１７８が操作者に再度報知するので、検査部１７６による検査が停止される状況を回避することがより期待できる。また、操作者への報知によって、操作者によりデータがバックアップされることが期待できる。 If the variable dcap reaches the constant Thw 2 before the inspection by the inspection unit 176 is stopped, the inspection control unit 178 notifies the operator again, thus avoiding the situation where the inspection by the inspection unit 176 is stopped. You can expect more. Moreover, it can be expected that data is backed up by the operator by notifying the operator.
　上記の実施形態のＸ線検査装置１００は、ネットワークを介して接続されたサーバ装置と通信する通信部１８１をさらに備える。変数ｄｃａｐが定数Ｔｈｓに到達した場合に、検査制御部１７８は、通信部１８１を介して、ＨＤＤ１７４に記憶されているデータをサーバ装置に転送してもよい。 The X-ray inspection apparatus 100 of the above embodiment further includes a communication unit 181 that communicates with a server apparatus connected via a network. When the variable dcap reaches the constant Ths, the inspection control unit 178 may transfer the data stored in the HDD 174 to the server device via the communication unit 181.
　また、上記の実施形態のＸ線検査装置１００は、可搬記録媒体であるＵＳＢメモリ１８２をさらに備える。変数ｄｃａｐが定数Ｔｈｓに到達した場合に、検査制御部１７８は、ＨＤＤ１７４に記憶されているデータをＵＳＢメモリ１８２に転送してもよい。 In addition, the X-ray inspection apparatus 100 of the above embodiment further includes a USB memory 182 that is a portable recording medium. When the variable dcap reaches the constant Ths, the inspection control unit 178 may transfer the data stored in the HDD 174 to the USB memory 182.
　以上のように、変数ｄｃａｐが定数Ｔｈｓに到達した場合に、データがサーバ装置およびＵＳＢメモリ１８２の少なくとも一方に転送されるので、データの記憶漏れが抑制される。 As described above, when the variable dcap reaches the constant Ths, data is transferred to at least one of the server device and the USB memory 182, so that data storage leakage is suppressed.
　（７）変形例
　検査制御部１７８は、累積容量に応じて、操作入力に基づく検査の実行が可能である実行可能状態と、検査の実行が不可能である実行禁止状態とを切り替えてもよい。より詳細には、図５において、検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｓ以上であると判定する場合に（ステップＳ１０１でＹＥＳ）、検査部１７６による検査を停止すると共に（ステップＳ１０２）、実行可能状態から実行禁止状態に遷移させてもよい。これにより、誤った操作によって検査が続行される状況を回避することができる。その後、表示部１５０がデータの削除を指示する操作入力を受け付けた場合に、検査制御部１７８は、ＨＤＤ１７４に記憶されているデータを削除して、実行禁止状態から実行可能状態に遷移させてもよい。検査制御部１７８は、操作者の削除指示を待ってデータを削除するので、サーバ装置および／またはＵＳＢメモリ１８２へのデータ転送の完了が操作者によって確認された後に、操作者がデータを削除指示することが期待できる。また、検査部１７６による検査が停止された場合に、操作入力に基づく検査の実行が禁止されるので、誤った操作によって検査が続行される状況を回避することができる。 (7) Modification The inspection control unit 178 may switch between an executable state in which an inspection based on operation input can be performed and an execution prohibited state in which the inspection cannot be performed, according to the accumulated capacity. . More specifically, in FIG. 5, when the inspection control unit 178 determines that the variable dcap is equal to or greater than the constant Ths (YES in step S101), the inspection control unit 178 stops the inspection by the inspection unit 176 (step S102) and executes it. You may make a transition from the possible state to the prohibited state. As a result, it is possible to avoid a situation in which the inspection is continued due to an erroneous operation. Thereafter, when the display unit 150 accepts an operation input for instructing deletion of data, the inspection control unit 178 may delete the data stored in the HDD 174 and transition from the execution prohibited state to the executable state. Good. Since the inspection control unit 178 waits for the operator's deletion instruction and deletes the data, after the operator confirms that the data transfer to the server device and / or the USB memory 182 is completed, the operator instructs to delete the data. Can be expected to do. Further, when the inspection by the inspection unit 176 is stopped, the execution of the inspection based on the operation input is prohibited, so that it is possible to avoid a situation where the inspection is continued due to an erroneous operation.
　検査制御部１７８は、変数ｄｃａｐが定数Ｔｈｓ以上であると判定する場合に（ステップＳ１０１でＹＥＳ）、検査部１７６による検査を停止すると共に（ステップＳ１０２）、エラー画面を表示部１５０に表示してもよい。また、ＨＤＤ１７４に記憶されたデータのバックアップを操作者に促す画面を表示してもよい。 When the inspection control unit 178 determines that the variable dcap is equal to or greater than the constant Ths (YES in step S101), the inspection control unit 178 stops the inspection by the inspection unit 176 (step S102) and displays an error screen on the display unit 150. Also good. In addition, a screen that prompts the operator to back up data stored in the HDD 174 may be displayed.
　以上の説明では、Ｘ線検査装置１００は、通信部１８１とＵＳＢメモリ１８２の両方を備えたが、いずれか一方のみを備えてもよい。 In the above description, the X-ray inspection apparatus 100 includes both the communication unit 181 and the USB memory 182, but may include only one of them.
　以上の説明では、検査制御部１７８は、警告画面等を表示部１５０に表示することによって、操作者に報知したが、音声等の他の報知手段によって報知してもよい。 In the above description, the inspection control unit 178 notifies the operator by displaying a warning screen or the like on the display unit 150. However, the inspection control unit 178 may notify the operator by other notification means such as voice.
　以上の説明では、表示部１５０がデータの削除を指示する操作入力を受け付けた場合に、検査制御部１７８は、ＨＤＤ１７４に記憶されているデータを削除したが、バックアップの有無に応じて、データを削除するかを決定してもよい。具体的には、検査制御部１７８は、バックアップを実行していなければ、ＨＤＤ１７４に記憶されているデータを削除せずに、バックアップが実行されていない旨を表示部１５０に表示してもよい。その後、バックアップが実行された後、表示部１５０がデータの削除を指示する操作入力を受け付けた場合に、検査制御部１７８は、ＨＤＤ１７４に記憶されているデータを削除してもよい。 In the above description, when the display unit 150 receives an operation input instructing data deletion, the inspection control unit 178 deletes the data stored in the HDD 174. You may decide whether to delete. Specifically, if the backup is not executed, the inspection control unit 178 may display on the display unit 150 that the backup is not executed without deleting the data stored in the HDD 174. Thereafter, after the backup is executed, the inspection control unit 178 may delete the data stored in the HDD 174 when the display unit 150 receives an operation input instructing the deletion of the data.
　以上の説明では、検査結果に関するデータのバックアップは、操作者の操作を介さずに実行されたが、操作者の操作を介して実行されてもよい。例えば、検査制御部１７８は、表示部１５０に対する操作者の操作入力に応じて、メニュー画面からバックアップ実行画面に遷移させてもよい。そして、バックアップ実行画面において、表示部１５０がバックアップの実行指示を操作者から受け付けた場合に、バックアップを実行してもよい。 In the above description, the backup of the data relating to the inspection result is performed without the operator's operation, but may be performed through the operator's operation. For example, the inspection control unit 178 may transition from the menu screen to the backup execution screen in response to an operation input by the operator on the display unit 150. Then, on the backup execution screen, backup may be executed when the display unit 150 receives an instruction to execute backup from the operator.
　以上の説明では、検査制御部１７８は、検査部１７６による検査を停止した場合に、ＨＤＤ１７４に記憶されているデータを外部に一括転送したが、検査毎にリアルタイムに転送してもよい。この場合に、検査結果に関するデータは、管理装置によって管理されてもよい。以下、詳細に説明する。 In the above description, when the inspection by the inspection unit 176 stops the inspection control unit 178, the data stored in the HDD 174 is collectively transferred to the outside, but may be transferred in real time for each inspection. In this case, the data related to the inspection result may be managed by the management device. Details will be described below.
　（７－１）検査システムの構成
　図６は、検査システムを説明する図である。検査システムは、Ｘ線検査装置２００と、管理装置３００とを含んで構成される。Ｘ線検査装置２００と管理装置３００は、ＬＡＮ等のネットワーク４００を介して接続される。Ｘ線検査装置２００は、既に説明したように、被検査物品である商品Ｇの生産ラインに配置され、商品Ｇ中の異物の有無を検査する。そして、検査結果に関するデータを記憶すると共に、管理装置３００に逐次送信する。管理装置３００は、Ｘ線検査装置２００から送信される検査結果に関するデータを受信し、管理する。 (7-1) Configuration of Inspection System FIG. 6 is a diagram for explaining the inspection system. The inspection system includes an X-ray inspection apparatus 200 and a management apparatus 300. The X-ray inspection apparatus 200 and the management apparatus 300 are connected via a network 400 such as a LAN. As already described, the X-ray inspection apparatus 200 is arranged on the production line of the product G that is the article to be inspected, and inspects the presence or absence of foreign matter in the product G. And while storing the data regarding a test result, it transmits to the management apparatus 300 sequentially. The management apparatus 300 receives and manages data related to the inspection result transmitted from the X-ray inspection apparatus 200.
　（７－２）Ｘ線検査装置２００および管理装置３００のブロック図
　図７は、Ｘ線検査装置２００および管理装置３００のブロック図である。図７において、図３と同一の符号を付した要素は、図３において説明した要素と同一の機能及び構成を有する。 (7-2) Block diagram of X-ray inspection apparatus 200 and management apparatus 300 FIG. 7 is a block diagram of the X-ray inspection apparatus 200 and management apparatus 300. 7, elements denoted by the same reference numerals as those in FIG. 3 have the same functions and configurations as the elements described in FIG.
　データ書込部２０１は、検査部１７６による検査が実行される度に、検査結果に関するデータをＨＤＤ１７４に記憶すると共に、通信部２０３を介して、管理装置３００に送信する。 The data writing unit 201 stores the data related to the inspection result in the HDD 174 and transmits it to the management apparatus 300 via the communication unit 203 every time the inspection unit 176 performs the inspection.
　検査制御部２０２は、図３の検査制御部１７８と同様に、ＨＤＤ１７４におけるデータの累積容量を監視して、累積容量に応じて、検査部１７６を制御すると共に、警告画面、エラー画面等を表示部１５０に表示する。加えて、検査制御部２０２は、ネットワーク４００への接続状態を監視する。そして、接続状態が不良である場合、例えばネットワークが切れた場合に、データ書込部２０１は、検査結果に関するデータを管理装置３００に送信せずに、ＵＳＢメモリ１８２に記憶する。その後、ＵＳＢメモリ１８２のデータが操作者によって管理装置３００に転送されることによって、管理装置３００における、接続状態が不良である期間のデータの欠落を回避することができる。なお、検査制御部２０２は、ＵＳＢメモリ１８２への記憶を操作者に促す警告画面を表示部１５０に表示してもよい。操作者は、メニュー画面を操作することによって、検査結果に関するデータをＵＳＢメモリ１８２に記憶することができる。 Similar to the inspection control unit 178 of FIG. 3, the inspection control unit 202 monitors the accumulated capacity of data in the HDD 174, controls the inspection unit 176 according to the accumulated capacity, and displays a warning screen, an error screen, and the like. Displayed on the unit 150. In addition, the inspection control unit 202 monitors the connection state to the network 400. If the connection state is bad, for example, when the network is disconnected, the data writing unit 201 stores the data related to the inspection result in the USB memory 182 without transmitting the data to the management apparatus 300. Thereafter, the data in the USB memory 182 is transferred to the management apparatus 300 by the operator, so that it is possible to avoid data loss during the period in which the connection state in the management apparatus 300 is bad. Note that the inspection control unit 202 may display a warning screen that prompts the operator to store in the USB memory 182 on the display unit 150. The operator can store data related to the inspection result in the USB memory 182 by operating the menu screen.
　通信部２０３は、ネットワーク４００を介して、管理装置３００と通信する。 The communication unit 203 communicates with the management apparatus 300 via the network 400.
　管理装置３００は、制御部３１０、通信部３２０、および記憶部３３０を含んで構成される。 The management apparatus 300 includes a control unit 310, a communication unit 320, and a storage unit 330.

　記憶部３３０は、通信部３２０により受信されるデータを記憶する。 The storage unit 330 stores data received by the communication unit 320.
　制御部３１０は、ＣＰＵ３１１、ＲＯＭ３１２、ＲＡＭ３１３、およびＨＤＤ３１４等から構成されるコンピュータである。ＣＰＵ３１１、ＲＯＭ３１２、ＲＡＭ３１３、およびＨＤＤ３１４は、アドレスバスおよびデータバス等のバスラインを介して相互に接続される。ＣＰＵ３１１がＲＯＭ３１２に記憶されている制御プログラムを実行することによって、ＣＰＵ３１１は、記憶制御部３１５としての役割を果たす。 The control unit 310 is a computer that includes a CPU 311, a ROM 312, a RAM 313, an HDD 314, and the like. The CPU 311, the ROM 312, the RAM 313, and the HDD 314 are connected to each other via bus lines such as an address bus and a data bus. When the CPU 311 executes the control program stored in the ROM 312, the CPU 311 plays a role as the storage control unit 315.
　記憶制御部３１５は、ＵＳＢメモリ１８２が管理装置３００のＵＳＢポートに差し込まれると、ＵＳＢメモリ１８２に記憶されたデータのうち、ＵＳＢメモリ１８２に記憶されたデータとＨＤＤ３１４に記憶されたデータとの差分を取得する。そして、取得した差分のデータをＨＤＤ３１４に記憶する。記憶制御部３１５は、検査結果に関するデータのそれぞれに付与されたＩＤによって、どの検査結果に関するデータが必要であるかを判定することができる。 When the USB memory 182 is inserted into the USB port of the management apparatus 300, the storage control unit 315 determines the difference between the data stored in the USB memory 182 and the data stored in the HDD 314 among the data stored in the USB memory 182. To get. Then, the acquired difference data is stored in the HDD 314. The storage control unit 315 can determine which test result data is necessary based on the ID assigned to each of the test result data.
　以上のように、ネットワーク４００が切れた場合には、ＵＳＢメモリ１８２に記憶されたデータとＨＤＤ３１４に記憶されたデータとの差分がＨＤＤ３１４に記憶されるので、ＨＤＤ３１４でのデータの欠落を抑制することができる。 As described above, when the network 400 is disconnected, the difference between the data stored in the USB memory 182 and the data stored in the HDD 314 is stored in the HDD 314, so that data loss in the HDD 314 is suppressed. Can do.
　以上の説明では、記憶制御部３１５は、ＵＳＢメモリ１８２に記憶されたデータとＨＤＤ３１４に記憶されたデータとの差分を取得したが、ＵＳＢメモリ１８２に記憶された全データを取得してもよい。 In the above description, the storage control unit 315 acquires the difference between the data stored in the USB memory 182 and the data stored in the HDD 314, but may acquire all the data stored in the USB memory 182.
　また、ネットワーク４００の接続状態が良好になった場合、すなわちネットワーク４００の接続が回復した場合に、記憶制御部３１５は、ＨＤＤ１７４からデータを取得してもよい。この場合に、ＨＤＤ１７４に記憶されたデータとＨＤＤ３１４に記憶されたデータとの差分をＨＤＤ３１４に記憶してもよい。検査制御部２０２は、ＨＤＤ３１４による記憶状況を記憶制御部３１５に問い合わせてもよい。検査制御部２０２による問い合わせがあれば、記憶制御部３１５は、ＨＤＤ３１４によるデータの記憶状況を示す情報を検査制御部２０２に送信してもよい。そして、検査制御部２０２は、記憶制御部３１５から取得される当該情報に応じて、ＨＤＤ１７４に記憶されたデータを削除してもよい。取得した情報がバックアップ実行中である旨を示せば、検査制御部２０２は、ＨＤＤ１７４に記憶されたデータを削除せずに、管理装置３００においてバックアップが実行中である旨を表示部１５０に表示してもよい。また、取得した情報がどこまでバックアップが完了したかを示せば、ＨＤＤ１７４に記憶されたデータのうち、バックアップが完了したデータを削除してもよい。 In addition, when the connection state of the network 400 becomes good, that is, when the connection of the network 400 is restored, the storage control unit 315 may acquire data from the HDD 174. In this case, the difference between the data stored in the HDD 174 and the data stored in the HDD 314 may be stored in the HDD 314. The inspection control unit 202 may inquire the storage control unit 315 about the storage status of the HDD 314. If there is an inquiry from the inspection control unit 202, the storage control unit 315 may transmit information indicating the data storage status of the HDD 314 to the inspection control unit 202. Then, the inspection control unit 202 may delete the data stored in the HDD 174 in accordance with the information acquired from the storage control unit 315. If the acquired information indicates that the backup is being executed, the inspection control unit 202 displays on the display unit 150 that the backup is being executed in the management apparatus 300 without deleting the data stored in the HDD 174. May be. In addition, if the acquired information indicates how far the backup is completed, the data that has been backed up among the data stored in the HDD 174 may be deleted.
　以上のように、ＨＤＤ３１４によるデータの記憶状況を示す情報に応じて、ＨＤＤ１７４に記憶されたデータを削除するので、記憶が完了していない状態で、ＨＤＤ１７４に記憶されたデータが削除される状況を回避できる。 As described above, since the data stored in the HDD 174 is deleted according to the information indicating the data storage status of the HDD 314, the situation in which the data stored in the HDD 174 is deleted in a state where the storage is not completed. Can be avoided.
　以上の説明では、検査システムは、１つのＸ線検査装置１００を含む構成であったが、複数のＸ線検査装置を含んでもよいし、他の検査装置を含んでもよい。 In the above description, the inspection system includes one X-ray inspection apparatus 100. However, the inspection system may include a plurality of X-ray inspection apparatuses or other inspection apparatuses.
　以上の説明では、検査制御部２０２は、ネットワーク４００への接続状態を監視したが、ネットワーク４００への接続状態を監視しなくてもよい。この場合には、操作者は、必要に応じて、ＨＤＤ１７４に記憶されているデータをＵＳＢメモリ１８２に転送するための操作を行えばよい。 In the above description, the inspection control unit 202 monitors the connection state to the network 400, but does not have to monitor the connection state to the network 400. In this case, the operator may perform an operation for transferring data stored in the HDD 174 to the USB memory 182 as necessary.
　以上の説明では、可搬記録媒体であるバックアップ記憶部としてＵＳＢメモリを例に挙げたが、ＣＦカード、ＳＤカード、および外付けハードディスク等をバックアップ記憶部として挙げることもできる。 In the above description, a USB memory is taken as an example of a backup storage unit that is a portable recording medium, but a CF card, an SD card, an external hard disk, and the like can also be mentioned as a backup storage unit.
　以上の説明では、検査装置としてＸ線検査装置を例に挙げて説明したが、上述の態様は、Ｘ線検査装置に限らず様々な検査装置に適用し得る。例えば、商品Ｇ中の金属の有無を検査する金属検査装置、商品Ｇの重量をチェックするウェイトチェッカ等にも適用できる。すなわち、商品Ｇに対する検査の内容に関わらず、商品Ｇの検査結果に関するデータを逐次記憶する検査装置に適用できる。 In the above description, an X-ray inspection apparatus has been described as an example of the inspection apparatus. However, the above-described aspect is applicable not only to the X-ray inspection apparatus but also to various inspection apparatuses. For example, the present invention can be applied to a metal inspection apparatus that inspects the presence or absence of metal in the product G, a weight checker that checks the weight of the product G, and the like. That is, the present invention can be applied to an inspection apparatus that sequentially stores data relating to the inspection result of the product G regardless of the content of the inspection of the product G.
