Abstract

PROBLEM TO BE SOLVED: To safely perform emergency shutdown of an operation of each device of a component mounting line upon earthquake occurrence.SOLUTION: An emergency earthquake prompt report receiver 34 for receiving an emergency earthquake prompt report submitted from the meteorological agency or the like is set. The emergency earthquake prompt report received by the emergency earthquake prompt report receiver 34 is transmitted to a manufacturing management computer 31 of a component mounting line 10. The manufacturing management computer 31 calculates a residual time until a S wave prediction arrival time from a current time on the basis of S wave prediction arrival time information of the emergency earthquake prompt report received, and determines whether there is a residual time for operating devices 13, 14, and 15 until the recover after emergency shutdown is easily performed. In the device which has no residual time for being operated until the recover after the emergency shutdown becomes easy within the residual time, the emergency shutdown of the operation is immediately performed. In the device which has residual time for being operated until the recover after the emergency shutdown becomes easy within the residual time, non-immediate emergency shutdown in which the emergency shutdown is performed after the operation is performed until the recover after the emergency shutdown becomes easy is performed.SELECTED DRAWING: Figure 1

Description

本発明は、部品実装ラインを構成する複数の装置の稼働を地震発生時に緊急停止させる部品実装ラインの地震発生時緊急停止システムに関する発明である。   The present invention relates to an emergency stop system at the time of occurrence of an earthquake of a component mounting line that makes an emergency stop of operations of a plurality of devices constituting the component mounting line when an earthquake occurs.

特許文献１（特開２０１４−４９０２９号公報）に記載されているように、ワークを加工する工作機械の分野では、地震発生時に、気象庁等の外部機関から配信される緊急地震速報を工場で受信して工作機械の稼働を緊急停止させるシステムが提案されている。この工作機械の地震発生時緊急停止システムでは、緊急地震速報によって工作機械の稼働を緊急停止させる際に、機械軸、工具、ワークが損傷しない位置で停止させることを目的として、ワーク加工中か、ワーク交換中か、工具交換中かを判定して、ワーク加工中の場合は、機械軸を逆移動させて工具をワークの非加工位置まで戻してから機械軸を停止させ、ワーク交換中の場合は、ワーク交換終了後に機械軸を停止させ、工具交換中の場合は、工具交換終了後に機械軸を停止させるようにしている。   As described in Patent Document 1 (Japanese Patent Laid-Open No. 2014-49029), in the field of machine tools for machining workpieces, an earthquake early warning distributed from an external organization such as the Japan Meteorological Agency is received at the factory when an earthquake occurs. Thus, a system for urgently stopping the operation of the machine tool has been proposed. In this emergency stop system at the time of earthquake occurrence of machine tools, when stopping the operation of the machine tool by emergency earthquake warning, the workpiece axis is being processed for the purpose of stopping at a position where the machine axis, tool, workpiece is not damaged, When the workpiece is being changed or the tool is being changed, if the workpiece is being machined, the machine axis is moved backward to return the tool to the non-working position of the workpiece and then the machine axis is stopped. The machine axis is stopped after the work change, and when the tool is being changed, the machine axis is stopped after the tool change.

特開２０１４−４９０２９号公報JP 2014-49029 A

回路基板に電子部品を実装する部品実装ラインの分野においても、工作機械と同様に、地震発生時に部品実装ラインの各装置の稼働を緊急停止させるシステムの開発がユーザーから要求されるようになってきている。   In the field of component mounting lines that mount electronic components on circuit boards, as with machine tools, users have been required to develop systems that urgently stop the operation of each component mounting line when an earthquake occurs. ing.

上述した特許文献１の工作機械の地震発生時緊急停止システムでは、緊急地震速報を受信したときに、ワーク加工中の場合は、機械軸を逆移動させて工具をワークの非加工位置まで戻してから機械軸を停止させ、ワーク交換中の場合は、ワーク交換終了後に機械軸を停止させ、工具交換中の場合は、工具交換終了後に機械軸を停止させるようにしているが、緊急地震速報を受信してから地震の揺れが到達するまでの時間が短い場合は、上述した緊急停止の準備動作を行う時間的な余裕がなく、緊急停止前に地震の揺れが到達してしまう可能性がある。   In the emergency stop system at the time of earthquake occurrence of the machine tool described in Patent Document 1 described above, when the earthquake early warning is received, if the workpiece is being machined, the machine axis is moved backward to return the tool to the non-machining position of the workpiece. If the workpiece is being changed, the machine axis is stopped after the workpiece is changed.If the tool is being changed, the machine axis is stopped after the tool is changed. If the time from the reception to the arrival of the earthquake shake is short, there is no time to perform the emergency stop preparation operation described above, and the earthquake shake may arrive before the emergency stop. .

一般に、部品実装ラインには、ワークを加工する工作機械は含まれないため、特許文献１の工作機械の地震発生時緊急停止システムの技術思想を部品実装ラインの地震発生時緊急停止システムにそのまま適用できるものではない。部品実装ラインの地震発生時緊急停止システムの開発にあたっては、部品実装ラインを構成する部品実装機等の装置特有の事情を考慮する必要がある。   In general, since the component mounting line does not include machine tools that process workpieces, the technical concept of the emergency stop system for earthquakes of machine tools disclosed in Patent Document 1 is directly applied to the emergency stop system for earthquakes on component mounting lines. It is not possible. In developing an emergency stop system when an earthquake occurs in a component mounting line, it is necessary to consider the circumstances peculiar to devices such as a component mounting machine constituting the component mounting line.

本発明は、気象庁等の外部機関から発信される緊急地震速報には、地震による強い揺れを発生させるＳ波（Secondary Wave：第二の波）の予測到達時刻の情報が含まれる点に着目して、部品実装ラインを構成する複数の装置の稼働を地震発生時に緊急停止させる部品実装ラインの地震発生時緊急停止システムである。具体的には、外部機関から発信されるＳ波予測到達時刻情報を含む緊急地震速報を受信する緊急地震速報受信機と、前記緊急地震速報受信機で受信した緊急地震速報のＳ波予測到達時刻情報に基づいて現在時刻からＳ波予測到達時刻までの残り時間を算出する残り時間算出手段と、前記部品実装ラインの各装置の現在の稼働状態を判定して前記残り時間内に前記各装置を緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があるか否かを判定し、前記残り時間内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕がないと判定した装置については稼働を即時緊急停止し、前記残り時間内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があると判定した装置については緊急停止後の復旧が容易な状態になるまで稼働してから緊急停止させる非即時緊急停止を行う緊急停止手段とを備えた構成としたものである。   The present invention pays attention to the fact that the earthquake early warning that is transmitted from an external organization such as the Japan Meteorological Agency includes information on the predicted arrival time of the S wave (Secondary Wave) that generates a strong shake due to the earthquake. Thus, an emergency stop system at the time of occurrence of an earthquake of a component mounting line that makes an emergency stop of operation of a plurality of devices constituting the component mounting line when an earthquake occurs. Specifically, an earthquake early warning receiver that receives an earthquake early warning including S wave predicted arrival time information transmitted from an external organization, and an S wave estimated arrival time of the emergency earthquake early warning received by the emergency earthquake early warning receiver. A remaining time calculating means for calculating the remaining time from the current time to the S wave predicted arrival time based on the information, and determining the current operating state of each device on the component mounting line, so that each device is within the remaining time. Judge whether there is enough time to operate until recovery after an emergency stop is easy, and do not have time to operate until recovery after an emergency stop is easy within the remaining time For equipment that has been determined to be emergency stop immediately, and for equipment that has been determined to have enough time to operate within the remaining time until recovery after emergency stop is easy, recovery after emergency stop is easy In a state It is obtained by a structure in which a emergency stop means for performing non-immediate emergency stop for emergency stop from running until the.

この構成によれば、緊急地震速報の受信後に地震による強い揺れを発生させるＳ波が到達するまでの残り時間が短く、その残り時間内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕がないと判定した装置については稼働を即時緊急停止するため、Ｓ波が到達する前に当該装置を緊急停止させてＳ波の到達（地震による強い揺れ）に備えることができる。一方、緊急地震速報の受信からＳ波が到達するまでの残り時間が比較的長く、その残り時間内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があると判定した装置については、緊急停止後の復旧が容易な状態になるまで稼働してから緊急停止させる非即時緊急停止を行うため、Ｓ波が到達する前に当該装置を緊急停止後の復旧が容易な状態になるまで稼働してから緊急停止させてＳ波の到達に備えることができ、緊急停止後の復旧が容易になる。   According to this configuration, the remaining time until the arrival of the S-wave that generates strong shaking due to the earthquake after receiving the earthquake early warning is short, and the system operates until the recovery after the emergency stop becomes easy within the remaining time. Since the apparatus determined to have no time allowance is immediately urgently stopped, the apparatus can be urgently stopped before the S wave arrives to prepare for the arrival of the S wave (strong shaking due to an earthquake). On the other hand, a device that has determined that the remaining time from the reception of the earthquake early warning to the arrival of the S wave is relatively long, and that there is time to operate until it becomes easy to recover after an emergency stop within the remaining time In order to perform a non-immediate emergency stop that is operated until the recovery after an emergency stop becomes easy, and then performs an emergency stop, the device is made ready for recovery after an emergency stop before the S wave arrives. It is possible to prepare for the arrival of the S wave by urgently stopping after operating until it becomes easy, and recovery after the emergency stop is facilitated.

本発明の実施態様としては、部品実装ラインの各装置とネットワークで接続された生産管理コンピュータを、前記残り時間算出手段及び前記緊急停止手段としても機能させ、前記生産管理コンピュータから前記部品実装ラインの各装置に前記即時緊急停止又は前記非即時緊急停止の指令を送信するようにしても良い。   As an embodiment of the present invention, a production management computer connected to each component mounting line device via a network also functions as the remaining time calculating means and the emergency stop means, A command for the immediate emergency stop or the non-immediate emergency stop may be transmitted to each device.

この場合、生産管理コンピュータが、残り時間算出手段と緊急停止手段の両方の機能を持ち、残り時間の算出から各装置の緊急停止方法の判定までの全ての処理を一括して行うことになるため、生産管理コンピュータの処理能力に余裕が少ない場合には、処理速度が遅くなる可能性がある。   In this case, the production management computer has the functions of both the remaining time calculation means and the emergency stop means, and all processes from the calculation of the remaining time to the determination of the emergency stop method of each device are performed collectively. When the processing capacity of the production management computer is small, the processing speed may be slow.

従って、生産管理コンピュータの処理能力に余裕が少ない場合には、生産管理コンピュータが、残り時間の算出のみを行い、算出した残り時間の情報を部品実装ラインの各装置に送信して、部品実装ラインの各装置の制御部が、それぞれ生産管理コンピュータから受信した前記残り時間に基づいて前記即時緊急停止か前記非即時緊急停止かを判定するようにしても良い。このようにすれば、生産管理コンピュータの処理能力に余裕が少ない場合でも、部品実装ラインの各装置の制御部で、即時緊急停止か非即時緊急停止かを速やかに判定することができ、残り時間の算出から各装置の緊急停止方法の判定までの処理速度が遅くなることを防止できる。要するに、残り時間は、部品実装ラインの全ての装置に共通するデータであるため、生産管理コンピュータで残り時間を算出して部品実装ラインの各装置に送信するようにすれば、部品実装ラインの各装置の制御部で残り時間の算出処理を重複して行わずに済み、その分、部品実装ラインの各装置の制御部の処理負荷を軽減できる利点がある。   Therefore, when the production management computer has a small processing capacity, the production management computer only calculates the remaining time and sends the calculated remaining time information to each device on the component mounting line. The control unit of each of the apparatuses may determine whether the immediate emergency stop or the non-immediate emergency stop based on the remaining time received from the production management computer. In this way, even when the processing capacity of the production management computer is small, the controller of each device on the component mounting line can quickly determine whether it is an immediate emergency stop or a non-immediate emergency stop, and the remaining time It is possible to prevent the processing speed from the calculation of the above to the determination of the emergency stop method of each device from slowing down. In short, the remaining time is data common to all devices on the component mounting line, so if the remaining time is calculated by the production management computer and sent to each device on the component mounting line, each component mounting line There is an advantage that the processing load of the control unit of each device on the component mounting line can be reduced by that amount.

但し、本発明は、部品実装ラインの各装置の制御部が、残り時間の算出から各装置の緊急停止方法の判定までの全ての処理を行うようにしても良い。或は、部品実装ラインの複数の装置のいずれか１つの装置の制御部でのみ残り時間を算出して、その残り時間の情報を他の装置の制御部に送信するようにしても良く、この場合は、当該他の装置の制御部では、残り時間を算出する必要はない。   However, in the present invention, the control unit of each device on the component mounting line may perform all processes from the calculation of the remaining time to the determination of the emergency stop method of each device. Alternatively, the remaining time may be calculated only by the control unit of any one of a plurality of devices on the component mounting line, and information on the remaining time may be transmitted to the control unit of another device. In this case, it is not necessary for the control unit of the other device to calculate the remaining time.

部品実装ラインを構成する装置は、主に部品実装機であるが、その他、半田印刷機、フラックス塗布装置、接着剤塗布装置、検査装置等、部品実装に関連する作業を行う実装関連装置もある。部品実装機では、地震発生時に吸着ノズルが下降した状態で緊急停止すると、地震の揺れにより吸着ノズルが部品実装機内の回路基板、電子部品や他の物体と干渉してそれらが損傷する可能性があり、緊急停止後の復旧に手間がかかる。従って、部品実装機では、緊急停止後の復旧が容易な状態とは、部品実装動作が終了して吸着ノズルが上昇した状態である。この状態は、部品吸着から部品実装までの１サイクル分の動作を終了して吸着ノズルが上昇した状態であり、この状態であれば、地震の揺れにより吸着ノズルが部品実装機内の回路基板、電子部品や他の物体と干渉してそれらが損傷することを防止できる。   The devices that make up the component mounting line are mainly component mounting machines, but there are also other mounting related devices that perform work related to component mounting, such as solder printing machines, flux coating devices, adhesive coating devices, and inspection devices. . In component mounters, if an emergency stop occurs when the suction nozzle is lowered in the event of an earthquake, the suction nozzle may interfere with the circuit board, electronic components, or other objects in the component mounter and damage them. Yes, it takes time to recover after an emergency stop. Therefore, in the component mounter, the state where the recovery after the emergency stop is easy is a state where the component mounting operation is finished and the suction nozzle is raised. This state is the state where the operation for one cycle from component suction to component mounting has been completed and the suction nozzle has been raised. In this state, the suction nozzle is moved to the circuit board, electronic Interference with parts and other objects can be prevented from being damaged.

尚、緊急地震速報を受信したときに部品実装機が部品吸着動作中である場合に、残り時間内に部品実装動作を終了する時間的余裕はないが、残り時間内に部品吸着動作を終了して吸着ノズルを上昇させる時間的余裕があれば、部品吸着動作を終了して吸着ノズルを上昇させてから緊急停止させるようにしても良い。この場合、緊急停止により吸着ノズルに吸着した電子部品が脱落する可能性があるが、脱落した電子部品を復旧時に回収すれば良く、地震の揺れにより吸着ノズルが部品実装機内の回路基板、電子部品や他の物体と干渉することを防止できる。   If the component mounter is in the component picking operation when the earthquake early warning is received, there is no time to finish the component mounting operation within the remaining time, but the component picking up operation is completed within the remaining time. If there is enough time to raise the suction nozzle, the component suction operation may be terminated and the suction nozzle may be raised and then the emergency stop may be performed. In this case, there is a possibility that the electronic parts adsorbed to the suction nozzle may fall off due to an emergency stop, but it is only necessary to collect the dropped electronic parts at the time of recovery. And interference with other objects can be prevented.

また、部品実装ラインに搬入する回路基板には、基板識別情報（以下「基板ＩＤ」という）を記録又は記憶した基板ＩＤ記録部を設けると共に、前記部品実装ラインに搬入された回路基板の基板ＩＤ記録部から基板ＩＤを読み取って生産管理コンピュータに送信する基板ＩＤ読取り手段を設け、前記生産管理コンピュータは、前記緊急停止手段が前記部品実装ラインの各装置を緊急停止させたときに各装置内に搬入されている回路基板の基板ＩＤを各装置の識別情報と緊急停止の種別と関連付けて基板トレーサビリティ情報としてデータベースに保存して管理するようにしても良い。このようにすれば、生産途中で緊急停止した各装置内の部品実装基板を再稼働により完成させて製品として出荷する場合に、将来、その製品に何らかの不具合が発生したときに、データベースに保存されている基板トレーサビリティ情報に基づいて不具合の発生原因を容易に究明できると共に、地震発生時に生産途中であった製品を追跡調査して回収等の適切な措置を講じることができる。   The circuit board carried into the component mounting line is provided with a board ID recording unit that records or stores board identification information (hereinafter referred to as “board ID”), and the board ID of the circuit board carried into the component mounting line. A board ID reading means for reading the board ID from the recording unit and transmitting it to the production management computer is provided, and the production management computer is provided in each apparatus when the emergency stop means emergency stops each apparatus of the component mounting line. The board ID of the circuit board being carried in may be stored in the database as board traceability information in association with the identification information of each device and the type of emergency stop and managed. In this way, when a component mounting board in each device that has been urgently stopped during production is completed by re-operation and shipped as a product, it will be saved in the database if any failure occurs in that product in the future. The cause of the failure can be easily determined based on the substrate traceability information, and the product that was in the middle of production at the time of the earthquake can be traced and appropriate measures such as recovery can be taken.

また、部品実装ラインの各装置の稼働を非常停止スイッチの操作により非常停止させるライン非常停止システムが設けられている場合は、緊急地震速報受信機が緊急地震速報を受信したときに、緊急地震速報受信機から緊急地震速報をライン非常停止システムに送信して、そのライン非常停止システムは、前記緊急地震速報を受信したときに前記部品実装ラインの各装置を非常停止させるようにしても良い。このようにすれば、既存のライン非常停止システムを利用して、部品実装ラインの地震発生時緊急停止システムを低コストで構成できる利点がある。   In addition, if a line emergency stop system is provided to stop the operation of each device on the component mounting line by operating the emergency stop switch, the emergency earthquake warning is received when the earthquake early warning receiver receives the earthquake early warning. An emergency earthquake warning may be transmitted from the receiver to the line emergency stop system, and the line emergency stop system may cause each device of the component mounting line to emergency stop when the emergency earthquake warning is received. In this way, there is an advantage that the existing line emergency stop system can be used and the emergency stop system at the time of earthquake occurrence on the component mounting line can be configured at low cost.

以下、本発明を実施するための形態を具体化した４つの実施例１〜４を説明する。   Hereinafter, four Examples 1 to 4 embodying a mode for carrying out the present invention will be described.

本発明の実施例１を図１及び図２に基づいて説明する。
まず、図１に基づいて部品実装ライン１０の構成を説明する。 A first embodiment of the present invention will be described with reference to FIGS.
First, the configuration of the component mounting line 10 will be described with reference to FIG.

回路基板１１を搬送する搬送ライン１２には、回路基板１１に電子部品を実装する複数の部品実装機１４と、部品実装に関連する作業を行う実装関連装置（部品実装機以外の装置）が配列されている。ここで、実装関連装置は、例えば、半田印刷機１３、検査装置１５、フラックス塗布装置、接着剤塗布装置等である。以下、説明の便宜上、部品実装ライン１０を構成する半田印刷機１３、部品実装機１４、検査装置１５を、部品実装ライン１０の各装置１３，１４，１５と略して表記する場合がある。   A plurality of component mounters 14 for mounting electronic components on the circuit board 11 and mounting related devices (devices other than the component mounter) for performing operations related to component mounting are arranged on the transfer line 12 for transferring the circuit board 11. Has been. Here, the mounting-related apparatus is, for example, a solder printer 13, an inspection apparatus 15, a flux application apparatus, an adhesive application apparatus, or the like. Hereinafter, for convenience of explanation, the solder printer 13, the component mounter 14, and the inspection device 15 constituting the component mounting line 10 may be abbreviated as the respective devices 13, 14, 15 of the component mounting line 10.

各部品実装機１４のフィーダセット部（図示せず）には、それぞれ電子部品を供給するフィーダ１７が交換可能にセットされている。各部品実装機１４の実装ヘッド１８には、各フィーダ１７から供給される電子部品を吸着して回路基板１１に実装する１本又は複数本の吸着ノズル（図示せず）が交換可能に保持されている。   A feeder 17 that supplies electronic components is set in a feeder set section (not shown) of each component mounter 14 in a replaceable manner. One or a plurality of suction nozzles (not shown) for sucking the electronic components supplied from the feeders 17 and mounting them on the circuit board 11 are held in the mounting head 18 of each component mounting machine 14 in an exchangeable manner. ing.

搬送ライン１２に搬入する回路基板１１の上面のうちの部品実装領域の外側に、基板識別情報（以下「基板ＩＤ」と表記する）を記録又は記憶した基板ＩＤ記録部１９が設けられている。この基板ＩＤ記録部１９は、バーコード、２次元コード等のコードを記録したものでも良いし、電子的に記憶する電子タグ（ＲＦタグ、無線タグ、ＩＣタグ、電波タグ等とも呼ばれる）や、磁気的に記録する磁気テープ等を用いても良い。   A board ID recording unit 19 that records or stores board identification information (hereinafter referred to as “board ID”) is provided outside the component mounting area on the upper surface of the circuit board 11 to be carried into the transfer line 12. The board ID recording unit 19 may be a bar code, a code such as a two-dimensional code, or an electronic tag (also referred to as an RF tag, wireless tag, IC tag, radio wave tag, etc.) for electronic storage, You may use the magnetic tape etc. which magnetically record.

一方、搬送ライン１２の入口側（回路基板１１の投入側）には、回路基板１１の基板ＩＤ記録部１９に記録又は記憶された基板ＩＤを読み取る基板ＩＤ読取り手段としてリーダ２０が設けられている。   On the other hand, a reader 20 is provided on the entrance side of the transfer line 12 (the side on which the circuit board 11 is inserted) as a board ID reading means for reading the board ID recorded or stored in the board ID recording unit 19 of the circuit board 11. .

部品実装ライン１０の生産を管理・監視する生産管理コンピュータ３１は、部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５とネットワークで接続され、搬送ライン１２の入口側に配置したリーダ２０で、搬送ライン１２に投入された回路基板１１の基板ＩＤ記録部１９から基板ＩＤを読み取り、搬送ライン１２から搬出される回路基板１１の実装部品情報等を当該回路基板１１の基板ＩＤと関連付けて基板トレーサビリティ情報として記憶装置３２（データベース）に保存するようにしている。   A production management computer 31 that manages and monitors the production of the component mounting line 10 is connected to the controllers 23, 24, and 25 of the devices 13, 14, and 15 of the component mounting line 10 through a network and is connected to the entrance side of the transport line 12. The placed reader 20 reads the board ID from the board ID recording unit 19 of the circuit board 11 put into the transfer line 12, and the mounted component information and the like of the circuit board 11 carried out of the transfer line 12 are transferred to the board of the circuit board 11. The information is stored in the storage device 32 (database) as substrate traceability information in association with the ID.

更に、本実施例１では、後述する緊急地震速報の受信により部品実装ライン１０の各装置１３，１４，１５が緊急停止したときに、各装置１３，１４，１５に搬入されている回路基板１１の基板ＩＤを各装置１３，１４，１５の識別情報と後述する緊急停止の種別と関連付けて基板トレーサビリティ情報として記憶装置３２に保存するようにしている。   Further, in the first embodiment, when the devices 13, 14, and 15 of the component mounting line 10 are urgently stopped by receiving an earthquake early warning described later, the circuit board 11 carried into the devices 13, 14, and 15 is used. Are stored in the storage device 32 as substrate traceability information in association with the identification information of each device 13, 14, 15 and the type of emergency stop described later.

各部品実装機１４の制御部２４は、生産管理コンピュータ３１から送信されてくる生産ジョブ（生産プログラム）に従って、実装ヘッド１８を部品吸着位置→部品撮像位置→部品実装位置の経路で移動させて、フィーダ１７により供給される電子部品を実装ヘッド１８の吸着ノズルで吸着して当該電子部品を部品撮像用のカメラ（図示せず）で撮像して部品吸着位置のずれ量等を認識して当該電子部品をその吸着位置のずれ量分だけ位置補正して回路基板１１の実装位置に実装するという動作を繰り返して、当該回路基板１１に所定数の電子部品を実装して部品実装基板を生産する。   The control unit 24 of each component mounter 14 moves the mounting head 18 along a path of component suction position → component imaging position → component mounting position in accordance with a production job (production program) transmitted from the production management computer 31. The electronic component supplied by the feeder 17 is picked up by a suction nozzle of the mounting head 18 and the electronic component is picked up by a camera for picking up the component (not shown) to recognize the deviation amount of the component pick-up position and the like. By repeating the operation of correcting the position of the component by the amount of deviation of the suction position and mounting the component on the mounting position of the circuit board 11, a predetermined number of electronic components are mounted on the circuit board 11 to produce a component mounting board.

次に、部品実装ライン１０の地震発生時緊急停止システムの構成を説明する。
部品実装ライン１０を設置した工場内に、緊急地震速報受信機３４が設置され、この緊急地震速報受信機３４がルータ３５を介してネットワークで気象庁等の外部機関の緊急地震速報発信用のコンピュータ（図示せず）に接続され、気象庁等の外部機関の緊急地震速報発信用のコンピュータから発信される緊急地震速報が緊急地震速報受信機３４で受信されるようになっている。この緊急地震速報には、地震による強い揺れを発生させるＳ波（Secondary Wave：第二の波）の予測到達時刻の情報が含まれる。 Next, the configuration of the emergency stop system at the time of occurrence of an earthquake in the component mounting line 10 will be described.
In the factory where the component mounting line 10 is installed, an earthquake early warning receiver 34 is installed, and this emergency earthquake early warning receiver 34 is a network for sending an emergency earthquake early warning from an external organization such as the Japan Meteorological Agency via a router 35 ( The emergency earthquake bulletin receiver 34 is connected to an emergency earthquake bulletin receiver 34 connected to an emergency earthquake bulletin transmission computer of an external organization such as the Japan Meteorological Agency. This emergency earthquake bulletin includes information on the predicted arrival time of an S wave (Secondary Wave) that generates a strong shake due to the earthquake.

緊急地震速報受信機３４は、生産管理コンピュータ３１に接続され、緊急地震速報受信機３４で受信した緊急地震速報が生産管理コンピュータ３１に送信される。本実施例１では、生産管理コンピュータ３１は、後述する図２の地震発生時緊急停止プログラムを実行することで、緊急地震速報受信機３４で受信した緊急地震速報のＳ波予測到達時刻情報に基づいて現在時刻からＳ波予測到達時刻までの残り時間を算出する残り時間算出手段として機能すると共に、部品実装ライン１０の各装置１３，１４，１５の現在の稼働状態を判定して前記残り時間内に各装置１３，１４，１５を緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があるか否かを判定し、その判定結果に応じて「非即時緊急停止」と「即時緊急停止」のどちらか一方を選択して緊急停止する緊急停止手段としても機能する。例えば、部品実装ライン１０の各装置１３，１４，１５のうち、前記残り時間内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕がないと判定した装置については、当該装置の稼働を即時緊急停止する。一方、前記残り時間内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があると判定した装置については、当該装置を緊急停止後の復旧が容易な状態になるまで稼働してから緊急停止させる非即時緊急停止を行う。   The emergency earthquake bulletin receiver 34 is connected to the production management computer 31, and the emergency earthquake bulletin received by the emergency earthquake bulletin receiver 34 is transmitted to the production management computer 31. In the first embodiment, the production management computer 31 executes an emergency stop program at the time of occurrence of an earthquake shown in FIG. 2 to be described later, so that the S-wave predicted arrival time information of the emergency earthquake warning received by the earthquake early warning receiver 34 is used. In addition to functioning as remaining time calculating means for calculating the remaining time from the current time to the S wave predicted arrival time, the current operating state of each of the devices 13, 14, and 15 of the component mounting line 10 is determined to be within the remaining time. It is determined whether each device 13, 14, 15 has sufficient time to operate until recovery after an emergency stop is easy, and “non-immediate emergency stop” and “immediately” are determined according to the determination result. It also functions as an emergency stop means for selecting one of “Emergency Stop” and making an emergency stop. For example, among the devices 13, 14, and 15 of the component mounting line 10, for a device that has been determined not to have time to operate until it becomes easy to recover after an emergency stop within the remaining time, Immediate emergency stop of operation. On the other hand, for a device that is determined to have sufficient time to operate until recovery after an emergency stop is easy within the remaining time, the device operates until recovery after an emergency stop is easy. Make a non-immediate emergency stop after an emergency stop.

この際、生産管理コンピュータ３１は、部品実装ライン１０を構成する複数の装置１３，１４，１５の各々について、残り時間内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があるか否かを判定し、その時間的余裕があるか否かの判定は、残り時間内に装置１３，１４，１５の緊急停止が完了するように、緊急停止に要する時間も考慮して判定する。   At this time, the production management computer 31 has a time margin for operating each of the plurality of devices 13, 14, and 15 constituting the component mounting line 10 until the recovery after an emergency stop becomes easy within the remaining time. It is determined whether or not there is a time margin, and whether or not there is enough time is determined in consideration of the time required for the emergency stop so that the emergency stop of the devices 13, 14, and 15 is completed within the remaining time. To do.

ところで、部品実装機１４では、地震発生時に吸着ノズルが下降した状態で緊急停止すると、地震の揺れにより吸着ノズルが部品実装機１４内の回路基板１１、電子部品や他の物体と干渉してそれらが損傷する可能性があり、緊急停止後の復旧に手間がかかる。従って、部品実装機１４では、緊急停止後の復旧が容易な状態とは、部品実装動作が終了して吸着ノズルが上昇した状態である。この状態は、部品吸着から部品実装までの１サイクル分の動作を終了して吸着ノズルが上昇した状態であり、この状態であれば、地震の揺れにより吸着ノズルが部品実装機１４内の回路基板１１、電子部品や他の物体と干渉してそれらが損傷することを防止できる。   By the way, in the component mounting machine 14, when an emergency stop is performed with the suction nozzle lowered in the event of an earthquake, the suction nozzle interferes with the circuit board 11, electronic components, and other objects in the component mounting machine 14 due to the shaking of the earthquake. May be damaged, and it takes time to recover after an emergency stop. Therefore, in the component mounting machine 14, the state where the recovery after the emergency stop is easy is a state where the component mounting operation is finished and the suction nozzle is raised. This state is a state in which the operation of one cycle from component suction to component mounting is completed and the suction nozzle is raised. In this state, the suction nozzle is moved to the circuit board in the component mounting machine 14 due to the shaking of the earthquake. 11. It can prevent electronic parts and other objects from interfering with and damaging them.

以上説明した緊急地震速報受信時に部品実装ライン１０の各装置１３，１４，１５を「非即時緊急停止」又は「即時緊急停止」で緊急停止する処理は、生産管理コンピュータ３１によって図２の地震発生時緊急停止プログラムに従って次のように実行される。   The process of emergency stopping the devices 13, 14, and 15 of the component mounting line 10 by "non-immediate emergency stop" or "immediate emergency stop" when receiving the earthquake early warning described above is generated by the production management computer 31 in FIG. It is executed as follows according to the emergency stop program.

図２の地震発生時緊急停止プログラムは、部品実装ライン１０の稼働中に所定周期で繰り返し実行され、特許請求の範囲でいう残り時間算出手段及び緊急停止手段としての役割を果たす。本プログラムが起動されると、まずステップ１０１で、緊急地震速報受信機３４が緊急地震速報を受信したか否かを判定し、緊急地震速報を受信していないと判定されれば、以降の処理を行うことなく、本プログラムを終了する。   The emergency stop program at the time of occurrence of an earthquake in FIG. 2 is repeatedly executed at a predetermined cycle during operation of the component mounting line 10, and plays a role as remaining time calculation means and emergency stop means in the claims. When this program is started, first, at step 101, it is determined whether or not the earthquake early warning receiver 34 has received the earthquake early warning, and if it is determined that the earthquake early warning has not been received, the subsequent processing is performed. This program is terminated without performing

その後、本プログラムを起動したときに、上記ステップ１０１で、緊急地震速報受信機３４が緊急地震速報を受信したと判定されれば、ステップ１０２に進み、受信した緊急地震速報のＳ波予測到達時刻情報に基づいて現在時刻からＳ波予測到達時刻までの残り時間Ａを算出する。
残り時間Ａ＝Ｓ波予測到達時刻−現在時刻 Thereafter, when this program is started, if it is determined in step 101 that the earthquake early warning receiver 34 has received the earthquake early warning, the process proceeds to step 102 and the S earthquake predicted arrival time of the received earthquake early warning is received. Based on the information, a remaining time A from the current time to the predicted S wave arrival time is calculated.
Remaining time A = S wave predicted arrival time-current time

この後、ステップ１０３に進み、部品実装ライン１０の各装置１３，１４，１５の現在の稼働状態を判定して緊急停止後の復旧が容易な状態に到達させるまでに必要な稼働時間Ｂを算出する。この必要な稼働時間Ｂの算出は、各装置１３，１４，１５の各々について別々に行う。   Thereafter, the process proceeds to step 103, where the current operating state of each device 13, 14, 15 of the component mounting line 10 is determined, and the operating time B required to reach a state where recovery after an emergency stop is easy is calculated. To do. The calculation of the necessary operating time B is performed separately for each of the devices 13, 14, and 15.

この後、ステップ１０４に進み、残り時間Ａ内に各装置１３，１４，１５を緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があるか否かを判定する。この判定は、残り時間Ａから上記必要な稼働時間Ｂを差し引いた時間（Ａ−Ｂ）が各装置１３，１４，１５の緊急停止に要する時間Ｃよりも大きいか否かで判定する。
Ａ−Ｂ＞Ｃ
この判定も、各装置１３，１４，１５の各々について別々に行う。 Thereafter, the process proceeds to step 104, and it is determined whether or not there is time to operate each device 13, 14, 15 until the recovery after the emergency stop becomes easy within the remaining time A. This determination is made based on whether or not the time (AB) obtained by subtracting the necessary operating time B from the remaining time A is longer than the time C required for the emergency stop of each device 13, 14, 15.
A-B> C
This determination is also made for each of the devices 13, 14, and 15 separately.

上記ステップ１０４で、Ａ−Ｂ＞Ｃ、つまり残り時間Ａ内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があると判定された装置については、ステップ１０５に進み、当該装置を緊急停止後の復旧が容易な状態になるまで稼働してから緊急停止させる非即時緊急停止を行うように当該装置に指令して、ステップ１０７に進む。   In step 104 above, for A−B> C, that is, for the device that is determined to have time to operate until the recovery after the emergency stop is easy within the remaining time A, the process proceeds to step 105, The apparatus is instructed to perform a non-immediate emergency stop in which the apparatus is operated until it can be easily recovered after an emergency stop, and then the emergency stop is performed.

これに対し、上記ステップ１０４で、Ａ−Ｂ≦Ｃ、つまり残り時間Ａ内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕がないと判定された装置については、ステップ１０６に進み、当該装置の稼働を即時緊急停止させるように当該装置に指令して、ステップ１０７に進む。   On the other hand, for the device that has been determined in step 104 to have a time margin for operation until AB-C, that is, the remaining time A can be easily recovered after an emergency stop, step 106 is performed. Then, the apparatus is instructed to immediately stop the operation of the apparatus immediately, and the process proceeds to Step 107.

このステップ１０７では、部品実装ライン１０の各装置１３，１４，１５に搬入されている回路基板１１の基板ＩＤを各装置１３，１４，１５の識別情報と緊急停止の種別と関連付けて基板トレーサビリティ情報として記憶装置３２に保存して、本プログラムを終了する。   In this step 107, the board traceability information is obtained by associating the board ID of the circuit board 11 carried into each device 13, 14, 15 of the component mounting line 10 with the identification information of each device 13, 14, 15 and the type of emergency stop. And the program is terminated.

尚、本実施例１では、部品実装ライン１０の稼働中に図２の地震発生時緊急停止プログラムを所定周期で繰り返し実行するようにしたが、部品実装ライン１０の稼働中に緊急地震速報受信機３４が緊急地震速報を受信したときに、割り込み処理により、ステップ１０２以降の処理を実行するようにしても良い。   In the first embodiment, the emergency stop program at the occurrence of an earthquake shown in FIG. 2 is repeatedly executed at a predetermined cycle while the component mounting line 10 is in operation. When 34 receives the earthquake early warning, the processing after step 102 may be executed by interruption processing.

以上説明した本実施例１によれば、部品実装ライン１０を構成する複数の装置１３，１４，１５のうち、緊急地震速報の受信後に地震による強い揺れを発生させるＳ波が到達するまでの残り時間Ａが短く、その残り時間Ａ内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕がないと判定した装置については稼働を即時緊急停止するため、Ｓ波が到達する前に当該装置を緊急停止させてＳ波の到達（地震による強い揺れ）に備えることができる。一方、緊急地震速報の受信からＳ波が到達するまでの残り時間Ａが比較的長く、その残り時間Ａ内に緊急停止後の復旧が容易な状態になるまで稼働する時間的余裕があると判定した装置については、緊急停止後の復旧が容易な状態になるまで稼働してから緊急停止させる非即時緊急停止を行うため、Ｓ波が到達する前に当該装置を緊急停止後の復旧が容易な状態になるまで稼働してから緊急停止させてＳ波の到達に備えることができ、緊急停止後の復旧が容易になる。   According to the first embodiment described above, of the plurality of devices 13, 14, and 15 configuring the component mounting line 10, the remaining until the S wave that causes a strong shake due to the earthquake arrives after receiving the earthquake early warning. For a device that has been determined to have no time to operate until the time A is short and recovery after an emergency stop is easy within the remaining time A, the operation is immediately stopped immediately, so before the S wave arrives It is possible to prepare for the arrival of an S wave (strong shaking due to an earthquake) by urgently stopping the device. On the other hand, the remaining time A from the reception of the earthquake early warning to the arrival of the S wave is relatively long, and it is determined that there is time to operate until the recovery after the emergency stop becomes easy within the remaining time A. Since the non-immediate emergency stop is performed for the device that has been operated until the recovery after the emergency stop is easy and then the emergency stop is performed, the device can be easily recovered after the emergency stop before the S wave arrives. It is possible to prepare for the arrival of the S wave by urgently stopping after operating until it reaches a state, and recovery after the emergency stop is facilitated.

しかも、本実施例１では、緊急地震速報の受信時に部品実装ライン１０の各装置１３，１４，１５を緊急停止させたときに各装置１３，１４，１５に搬入されている回路基板１１の基板ＩＤを各装置１３，１４，１５の識別情報と緊急停止の種別と関連付けて基板トレーサビリティ情報として記憶装置３２に保存して管理するようにしたので、生産途中で緊急停止した各装置１３，１４，１５内の部品実装基板を再稼働により完成させて製品として出荷する場合に、将来、その製品に何らかの不具合が発生したときに、記憶装置３２に保存されている基板トレーサビリティ情報に基づいて不具合の発生原因を容易に究明できると共に、地震発生時に生産途中であった製品を追跡調査して回収等の適切な措置を講じることができる。   Moreover, in the first embodiment, when the devices 13, 14, and 15 of the component mounting line 10 are emergency stopped at the time of receiving the earthquake early warning, the circuit board 11 that is carried into the devices 13, 14, and 15 is loaded. Since the ID is associated with the identification information of each device 13, 14, 15 and the type of emergency stop and stored and managed in the storage device 32 as substrate traceability information, each device 13, 14, When the component mounting board in 15 is completed by re-operation and shipped as a product, if any trouble occurs in the product in the future, the trouble occurs based on the board traceability information stored in the storage device 32. The cause can be easily investigated, and products that were in production at the time of the earthquake can be traced and appropriate measures such as collection can be taken.

尚、本実施例１では、部品実装機１４の場合、「緊急停止後の復旧が容易な状態」とは、「部品実装動作が終了して吸着ノズルが上昇した状態」としたが、緊急地震速報を受信したときに部品吸着動作中である場合に、残り時間Ａ内に部品実装動作を終了する時間的余裕はないが、残り時間Ａ内に部品吸着動作を終了して吸着ノズルを上昇させる時間的余裕があれば、部品吸着動作を終了して吸着ノズルを上昇させてから緊急停止させるようにしても良い。この場合、緊急停止により吸着ノズルに吸着した電子部品が脱落する可能性があるが、脱落した電子部品を復旧時に回収すれば良く、地震の揺れにより吸着ノズルが部品実装機１４内の回路基板１１、電子部品や他の物体と干渉することを防止できる。   In the first embodiment, in the case of the component mounting machine 14, “the state where the recovery after the emergency stop is easy” is “the state where the component mounting operation is finished and the suction nozzle is raised”. If the component suction operation is in progress when receiving the preliminary report, there is no time to finish the component mounting operation within the remaining time A, but the component suction operation is completed within the remaining time A and the suction nozzle is raised. If there is a time allowance, the component suction operation may be terminated and the suction nozzle may be raised, and then the emergency stop may be performed. In this case, there is a possibility that the electronic component adsorbed to the suction nozzle due to an emergency stop may fall off. Interference with electronic parts and other objects can be prevented.

次に、図２及び図３を用いて本発明の実施例２を説明する。但し、上記実施例１と実質的に同じ部分については、説明を省略又は簡略化し、主として異なる部分について説明する。   Next, Embodiment 2 of the present invention will be described with reference to FIGS. However, description of the substantially same parts as those in the first embodiment will be omitted or simplified, and different parts will be mainly described.

上記実施例１では、生産管理コンピュータ３１が残り時間算出手段と緊急停止手段の両方の機能を持ち、生産管理コンピュータ３１が、残り時間Ａの算出から各装置１３，１４，１５の緊急停止方法の判定までの全ての処理を一括して行うことになるため、生産管理コンピュータ３１の処理能力に余裕が少ない場合には、処理速度が遅くなる可能性がある。   In the first embodiment, the production management computer 31 has the functions of both the remaining time calculation means and the emergency stop means, and the production management computer 31 determines the emergency stop method for each of the devices 13, 14, 15 from the calculation of the remaining time A. Since all the processes up to the determination are performed at once, the processing speed may be slowed down when the processing capacity of the production management computer 31 is small.

そこで、本実施例２では、生産管理コンピュータ３１は、図３の残り時間算出プログラムを実行することで、残り時間算出手段としてのみ機能して、緊急地震速報の受信時に残り時間Ａの算出のみを行い、算出した残り時間Ａの情報を部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５に送信する。そして、部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５は、それぞれ図４の地震発生時緊急停止プログラムを実行することで、それぞれ緊急停止手段として機能して、生産管理コンピュータ３１から受信した残り時間Ａに基づいて即時緊急停止か非即時緊急停止かを判定して、どちらかの方法で緊急停止するようにしている。以下、図３の残り時間算出プログラムと図４の地震発生時緊急停止プログラムの処理内容を説明する。   Therefore, in the second embodiment, the production management computer 31 functions only as the remaining time calculating means by executing the remaining time calculating program of FIG. 3 and only calculates the remaining time A when receiving the earthquake early warning. The information of the calculated remaining time A is transmitted to the control units 23, 24, 25 of the devices 13, 14, 15 of the component mounting line 10. The control units 23, 24, and 25 of the devices 13, 14, and 15 in the component mounting line 10 each function as an emergency stop unit by executing the emergency stop program at the occurrence of an earthquake shown in FIG. Based on the remaining time A received from the management computer 31, it is determined whether it is an immediate emergency stop or a non-immediate emergency stop, and an emergency stop is performed by either method. Hereinafter, the processing contents of the remaining time calculation program of FIG. 3 and the emergency stop program at the time of earthquake occurrence of FIG. 4 will be described.

図３の残り時間算出プログラムは、部品実装ライン１０の稼働中に生産管理コンピュータ３１によって所定周期で繰り返し実行される。本プログラムが起動されると、まず、ステップ２０１とステップ２０２の処理により、緊急地震速報受信機３４が緊急地震速報を受信したときに、受信した緊急地震速報のＳ波予測到達時刻情報に基づいて現在時刻からＳ波予測到達時刻までの残り時間Ａを算出する。
残り時間Ａ＝Ｓ波予測到達時刻−現在時刻 The remaining time calculation program in FIG. 3 is repeatedly executed at a predetermined cycle by the production management computer 31 while the component mounting line 10 is in operation. When this program is started, first, when the earthquake early warning receiver 34 receives the earthquake early warning by the processing of step 201 and step 202, it is based on the predicted S wave arrival time information of the received earthquake early warning. The remaining time A from the current time to the S wave predicted arrival time is calculated.
Remaining time A = S wave predicted arrival time-current time

この後、ステップ２０３に進み、算出した残り時間Ａの情報を部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５に送信して、本プログラムを終了する。   Thereafter, the process proceeds to step 203, where the calculated remaining time A information is transmitted to the control units 23, 24, 25 of the devices 13, 14, 15 of the component mounting line 10 and the program is terminated.

尚、本実施例２では、部品実装ライン１０の稼働中に図３の残り時間算出プログラムを所定周期で実行するようにしたが、緊急地震速報受信機３４が緊急地震速報を受信したときに、割り込み処理により、ステップ２０２以降の処理を実行するようにしても良い。   In the second embodiment, the remaining time calculation program of FIG. 3 is executed at a predetermined cycle while the component mounting line 10 is in operation. However, when the earthquake early warning receiver 34 receives the earthquake early warning, You may make it perform the process after step 202 by interruption process.

一方、図４の地震発生時緊急停止プログラムは、部品実装ライン１０の稼働中に各装置１３，１４，１５の制御部２３，２４，２５によって所定周期で繰り返し実行される。本プログラムが起動されると、まず、ステップ２１１で、生産管理コンピュータ３１が算出した残り時間Ａの情報（つまり残り時間Ａ経過後にＳ波が到達すること）を受信したか否かを判定し、残り時間Ａの情報を受信していないと判定されれば、以降の処理を行うことなく、本プログラムを終了する。   On the other hand, the emergency stop program at the occurrence of an earthquake in FIG. 4 is repeatedly executed at predetermined intervals by the control units 23, 24, and 25 of the devices 13, 14, and 15 while the component mounting line 10 is in operation. When this program is started, first, at step 211, it is determined whether or not the information of the remaining time A calculated by the production management computer 31 (that is, the S wave arrives after the remaining time A has elapsed) is received. If it is determined that the remaining time A information has not been received, the program is terminated without performing the subsequent processing.

その後、本プログラムを起動したときに、上記ステップ２１１で、残り時間Ａの情報を受信したと判定されれば、ステップ２１２〜２１６の処理を実行する。このステップ２１２〜２１６の処理は、実施例１で説明した図２のステップ１０３〜１０７の処理と同じである。   Thereafter, when this program is started, if it is determined in step 211 that information on the remaining time A has been received, the processing in steps 212 to 216 is executed. The processing in steps 212 to 216 is the same as the processing in steps 103 to 107 in FIG. 2 described in the first embodiment.

以上説明した本実施例２では、生産管理コンピュータ３１は、緊急地震速報の受信時に残り時間Ａの算出のみを行い、算出した残り時間Ａの情報を部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５に送信して、各装置１３，１４，１５の制御部２３，２４，２５が、それぞれ生産管理コンピュータ３１から受信した残り時間Ａに基づいて即時緊急停止か非即時緊急停止かを判定するようにしたので、生産管理コンピュータ３１の処理能力に余裕が少ない場合でも、部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５で、即時緊急停止か非即時緊急停止かを速やかに判定することができ、残り時間Ａの算出から各装置１３，１４，１５の緊急停止方法の判定までの処理速度が遅くなることを防止できる。要するに、残り時間Ａは、部品実装ライン１０の全ての装置１３，１４，１５に共通するデータであるため、生産管理コンピュータ３１で残り時間Ａを算出して部品実装ライン１０の各装置１３，１４，１５に送信するようにすれば、部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５で残り時間Ａの算出処理を重複して行わずに済み、その分、部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５の処理負荷を軽減できる利点がある。
その他、前記実施例１と同様の効果を得ることができる。 In the second embodiment described above, the production management computer 31 only calculates the remaining time A when receiving the earthquake early warning, and uses the information of the calculated remaining time A to each of the devices 13, 14, 15 of the component mounting line 10. Are sent to the control units 23, 24, and 25, and the control units 23, 24, and 25 of the devices 13, 14, and 15 receive the emergency stop or non-immediate based on the remaining time A received from the production management computer 31, respectively. Since the emergency stop is determined, even if the processing capacity of the production management computer 31 is small, the controller 23, 24, 25 of each device 13, 14, 15 of the component mounting line 10 can be used for immediate emergency stop. Or a non-immediate emergency stop can be quickly determined, and the processing speed from the calculation of the remaining time A to the determination of the emergency stop method of each device 13, 14, 15 can be prevented from slowing down. That. In short, since the remaining time A is data common to all the devices 13, 14, 15 of the component mounting line 10, the remaining time A is calculated by the production management computer 31 and each device 13, 14 of the component mounting line 10 is calculated. 15, it is not necessary to repeat the calculation process of the remaining time A in the control units 23, 24, 25 of the devices 13, 14, 15 of the component mounting line 10. There is an advantage that the processing load of the control units 23, 24, 25 of the devices 13, 14, 15 of the mounting line 10 can be reduced.
In addition, the same effects as those of the first embodiment can be obtained.

次に、本発明の実施例３を説明する。但し、上記実施例１と実質的に同じ部分については、説明を省略又は簡略化し、主として異なる部分について説明する。   Next, a third embodiment of the present invention will be described. However, description of the substantially same parts as those in the first embodiment will be omitted or simplified, and different parts will be mainly described.

本実施例３では、部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５が残り時間算出手段及び緊急停止手段として機能して、各装置１３，１４，１５の制御部２３，２４，２５で、それぞれ、実施例１で説明した図２の地震発生時緊急停止プログラムと同様の地震発生時緊急停止プログラムを所定周期で繰り返し実行することで、緊急地震速報の受信時に残り時間Ａの算出から各装置１３，１４，１５の緊急停止方法の判定までの全ての処理を実行するようにしている。   In the third embodiment, the control units 23, 24, and 25 of the devices 13, 14, and 15 of the component mounting line 10 function as remaining time calculating means and emergency stop means, and the control units of the devices 13, 14, and 15 are used. 23, 24, and 25, the emergency stop program at the time of earthquake occurrence similar to the emergency stop program at the time of earthquake occurrence shown in FIG. All processes from the calculation of the time A to the determination of the emergency stop method of each device 13, 14, 15 are executed.

この場合、緊急地震速報受信機３４で受信した緊急地震速報は、生産管理コンピュータ３１を経由して部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５に送信するようにしても良いし、或は、緊急地震速報受信機３４を部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５にネットワークで接続して、緊急地震速報受信機３４で受信した緊急地震速報を、生産管理コンピュータ３１を経由せずに、直接、部品実装ライン１０の各装置１３，１４，１５の制御部２３，２４，２５に送信するようにしても良い。   In this case, the earthquake early warning received by the earthquake early warning receiver 34 is transmitted to the control units 23, 24, 25 of the devices 13, 14, 15 of the component mounting line 10 via the production management computer 31. Alternatively, the earthquake early warning receiver 34 may be connected to the controllers 23, 24, and 25 of the devices 13, 14, and 15 of the component mounting line 10 via a network and received by the earthquake early warning receiver 34. The emergency earthquake bulletin may be transmitted directly to the control units 23, 24, 25 of the devices 13, 14, 15 of the component mounting line 10 without going through the production management computer 31.

また、部品実装ライン１０の複数の装置１３，１４，１５のいずれか１つの装置の制御部でのみ残り時間Ａを算出して、その残り時間Ａの情報を他の装置の制御部に送信するようにしても良く、この場合は、当該他の装置の制御部では、残り時間を算出する必要はない。
