図2において、パーツフィーダ13は、テープフィーダである。パーツフィーダ13は、内蔵したスプロケット13S(図3も参照)によって、リールRLに巻き付けられたキャリアテープCTを引き出して前後方向(Y軸方向)に搬送する。これにより、パーツフィーダ13は、搬送コンベア12側の端部に設けられた部品供給位置13Kに部品BHを供給する。ヘッド移動機構14は、例えばXYガントリー機構から成り、装着ヘッド15を水平面内で移動させる。
In FIG. 2, the parts feeder 13 is a tape feeder. The parts feeder 13 pulls out the carrier tape CT wound around the reel RL by the built-in sprocket 13S (see also FIG. 3) and conveys it in the front-rear direction (Y-axis direction). As a result, the parts feeder 13 supplies the parts BH to the parts supply position 13K provided at the end on the conveyor 12 side. The head moving mechanism 14 is composed of, for example, an XY gantry mechanism, and moves the mounting head 15 in a horizontal plane.

The mounting head 15 can raise and lower each nozzle 15N, and can rotate each nozzle 15N in the vertical direction (Z-axis direction). Further, the mounting head 15 can generate a vacuum suction force at the lower end of each nozzle 15N. When the mounting head 15 sucks the component BH from the part feeder 13, the nozzle 15N is lowered above the component supply position 13K, and a vacuum suction force is generated at the lower end of the nozzle 15N.
図2および図3において、基板認識カメラ16は、撮像光軸を下方に向けた姿勢で装着ヘッド15に取り付けられている。基板認識カメラ16は、装着ヘッド15と一体に水平面内方向に移動し、搬送コンベア12によって作業位置に位置決めされた基板KBを上方から撮像する。
In FIGS. 2 and 3, the substrate recognition camera 16 is attached to the mounting head 15 in a posture in which the image pickup optical axis is directed downward. The substrate recognition camera 16 moves inward in the horizontal plane integrally with the mounting head 15, and images the substrate KB positioned at the working position by the conveyor 12 from above.
図2において、部品認識カメラ17は、撮像光軸を上方に向けた姿勢で基台11に取り付けられている。部品認識カメラ17は、部品BHをピックアップした装着ヘッド15が部品認識カメラ17の上方を通って基板KB側に移動する際、部品BHを下方から撮像する。
In FIG. 2, the component recognition camera 17 is attached to the base 11 with the image pickup optical axis facing upward. The component recognition camera 17 captures the component BH from below when the mounting head 15 that picks up the component BH passes above the component recognition camera 17 and moves toward the substrate KB.
作業装置2は、作業装置制御部18を備えている(図2および図4)。作業装置制御部18は、作業装置2の各部の動作を制御する。具体的には、作業装置制御部18は、搬送コンベア12を作動させて基板KBの搬送と作業位置への位置決めとを行い、各パーツフィーダ13を作動させて部品供給位置13Kに部品BHを供給させる。また、作業装置制御部18は、ヘッド移動機構14を作動させて装着ヘッド15を水平面内方向で移動させる。また、作業装置制御部18は、装着ヘッド15が備える各ノズル15Nを昇降および回転させ、各ノズル15Nの下端に吸着力を発生させて、パーツフィーダ13が供給する部品BHを吸着させる。作業装置制御部18はまた、基板認識カメラ16の撮像動作によって得られる画像データに基づいて画像認識を行い、装着ヘッド15がノズル15Nに吸着させてピックアップした部品BHを部品認識カメラ17に撮像させて、部品BHの認識を行う。
The work device 2 includes a work device control unit 18 (FIGS. 2 and 4). The work device control unit 18 controls the operation of each unit of the work device 2. Specifically, the work device control unit 18 operates the transfer conveyor 12 to transfer the substrate KB and position it at the work position, and operates each part feeder 13 to supply the component BH to the component supply position 13K. Let me. Further, the working device control unit 18 operates the head moving mechanism 14 to move the mounting head 15 in the horizontal plane direction. Further, the working device control unit 18 raises and lowers and rotates each nozzle 15N included in the mounting head 15, generates an attraction force at the lower end of each nozzle 15N, and attracts the component BH supplied by the component feeder 13. The working device control unit 18 also performs image recognition based on the image data obtained by the image pickup operation of the substrate recognition camera 16, and causes the component recognition camera 17 to image the component BH picked up by the mounting head 15 attracted to the nozzle 15N. Then, the component BH is recognized.
作業ライン2Lを構成する各作業装置2は、基板KBに部品BHを装着する部品装着作業を行う場合、先ず、搬送コンベア12は、上流側から送られてきた基板KBを受け取って搬送し、作業位置に基板KBを位置決めする。基板KBが作業位置に位置決めされたら、ヘッド移動機構14は、装着ヘッド15を基板KBの上方に移動させる。これにより、基板認識カメラ16は基板KBを撮像し、作業装置制御部18は基板KBを認識する。
When each work device 2 constituting the work line 2L performs the component mounting work of mounting the component BH on the board KB, the transport conveyor 12 first receives and transports the board KB sent from the upstream side to perform the work. Position the board KB in position. When the board KB is positioned at the working position, the head moving mechanism 14 moves the mounting head 15 above the board KB. As a result, the board recognition camera 16 takes an image of the board KB, and the working device control unit 18 recognizes the board KB.
作業装置制御部18が基板KBを認識したら、ヘッド移動機構14は、装着ヘッド15をパーツフィーダ13の上方に移動させる。装着ヘッド15は、パーツフィーダ13の上方に移動したら、パーツフィーダ13が供給する部品BHを複数のノズル15Nそれぞれに吸着させてピックアップする。
When the working device control unit 18 recognizes the board KB, the head moving mechanism 14 moves the mounting head 15 above the parts feeder 13. When the mounting head 15 moves above the parts feeder 13, the parts BH supplied by the parts feeder 13 are attracted to each of the plurality of nozzles 15N and picked up.
装着ヘッド15が部品BHをピックアップしたら、ヘッド移動機構14は、装着ヘッド15にピックアップされた部品BHが部品認識カメラ17の上方を通過するように装着ヘッド15を移動させる。部品認識カメラ17は、部品BHが上方を通過するとき、部品BHを撮像する。作業装置制御部18は、部品認識カメラ17の撮像によって得られた画像に基づいて、部品BHの認識を行う。
After the mounting head 15 picks up the component BH, the head moving mechanism 14 moves the mounting head 15 so that the component BH picked up by the mounting head 15 passes above the component recognition camera 17. The component recognition camera 17 captures the component BH as the component BH passes above. The working device control unit 18 recognizes the component BH based on the image obtained by the image captured by the component recognition camera 17.
作業装置制御部18が部品BHを認識したら、ヘッド移動機構14は、装着ヘッド15を基板KBの上方に移動させる。装着ヘッド15は、ピックアップした部品BHを、基板KBに設定されている目標装着座標に装着する。装着ヘッド15が部品BHを目標装着座標に装着する際には、部品認識カメラ17を通じて行った部品BHの認識結果と、基板認識カメラ16を通じて行った基板KBの認識結果とに基づいた位置補正がなされる。
When the working device control unit 18 recognizes the component BH, the head moving mechanism 14 moves the mounting head 15 above the board KB. The mounting head 15 mounts the picked up component BH at the target mounting coordinates set on the board KB. When the mounting head 15 mounts the component BH at the target mounting coordinates, the position correction based on the recognition result of the component BH performed through the component recognition camera 17 and the recognition result of the board KB performed through the board recognition camera 16 is performed. Will be done.
このような装着ヘッド15の一連の動作が繰り返されることによって、基板KBに装着すべき部品BHが基板KBに装着される。その後、搬送コンベア12は、基板KBを作業装置2の下流側に搬出する。これにより、基板KBの1枚当たりの部品装着作業が終了する。
By repeating such a series of operations of the mounting head 15, the component BH to be mounted on the board KB is mounted on the board KB. After that, the transfer conveyor 12 carries out the substrate KB to the downstream side of the working device 2. This completes the component mounting work for each board KB.
作業装置2は、上記のような部品装着作業において、何らかのエラーが発生した場合には、そのエラーの発生を自己検出する自己検出機能を有している。そして、自己検出機能によってエラーの発生を検出した場合には、発生したエラーの情報(エラー情報)を管理装置3に送信する。そして、管理装置3は、複数の作業装置2のいずれかに発生したエラーの情報を、複数のリモート監視装置4のいずれかに送信(転送)する。なお、作業装置2から送信されるエラー情報は、例えば、基板認識カメラ16でエラー発生箇所を撮像した画像等から成る。
The work device 2 has a self-detection function that self-detects the occurrence of an error when an error occurs in the component mounting work as described above. Then, when the occurrence of an error is detected by the self-detection function, the information on the error (error information) that has occurred is transmitted to the management device 3. Then, the management device 3 transmits (transfers) the information of the error generated in any of the plurality of working devices 2 to any of the plurality of remote monitoring devices 4. The error information transmitted from the working device 2 includes, for example, an image obtained by capturing an error occurrence portion with the board recognition camera 16.
リモート監視装置4は、いわゆるリモート端末として機能する。リモート監視装置4は、例えば、パーソナルコンピュータから構成されている。リモート監視装置4は、管理装置3と有線で接続されていてもよいし、無線で接続されていてもよい。
The remote monitoring device 4 functions as a so-called remote terminal. The remote monitoring device 4 is composed of, for example, a personal computer. The remote monitoring device 4 may be connected to the management device 3 by wire or wirelessly.
図4は、本開示の一実施の形態におけるリモート操作システムの制御系統を示すブロック図である。図4において、リモート監視装置4は、リモート操作制御部21、リモート操作制御部21に繋がる入力部22および出力部23を備えている。リモート監視装置4がパーソナルコンピュータから構成されている場合、キーボード部が入力部22に相当し、モニタ部が出力部23に相当する(図1)。

In FIG. 4, the remote monitoring device 4 includes a remote operation control unit 21, an input unit 22 connected to the remote operation control unit 21, and an output unit 23. When the remote monitoring device 4 is composed of a personal computer, the keyboard unit corresponds to the input unit 22 and the monitor unit corresponds to the output unit 23 (FIG. 1).
図4において、リモート監視装置4のリモート操作制御部21は、管理装置3との間で通信(情報のやり取り)を行う。そして、リモート操作制御部21は、管理装置3から送信されてきたエラー情報(エラーの内容)を出力部23に表示する。これにより、リモート監視装置4で作業を行う作業者は、作業装置2で発生したエラーの内容を確認することができ、発生したエラーを解消するための操作(エラー解消操作)を入力部22から入力することができる。
In FIG. 4, the remote operation control unit 21 of the remote monitoring device 4 communicates (exchanges information) with the management device 3. Then, the remote operation control unit 21 displays the error information (error content) transmitted from the management device 3 on the output unit 23. As a result, the worker who works on the remote monitoring device 4 can confirm the content of the error generated in the work device 2, and the operation for resolving the generated error (error resolution operation) can be performed from the input unit 22. You can enter it.
作業者が入力部22から入力したエラー解消操作の情報は、リモート操作制御部21から管理装置3に送信される。管理装置3は、リモート監視装置4からエラーの情報の送信を受けた場合には、エラー解消操作の情報を、エラーが発生した作業装置2に送信(転送)する。
Information on the error resolution operation input by the operator from the input unit 22 is transmitted from the remote operation control unit 21 to the management device 3. When the management device 3 receives the error information transmission from the remote monitoring device 4, the management device 3 transmits (transfers) the error resolution operation information to the work device 2 in which the error has occurred.
管理装置3からエラー解消操作の情報を受け取った作業装置2は、受け取ったエラー解消操作に基づいて作動する。これにより、作業装置2は、発生したエラーの解消を試みる。その結果、エラーが解消した場合には、作業装置2は、エラーが解消した旨の情報(エラー解消情報)を管理装置3に送信する。管理装置3は、エラー解消情報をリモート監視装置4に送信(転送)する。リモート監視装置4のリモート操作制御部21は、管理装置3よりエラー解消情報を受け取った場合には、エラーが解消した旨の報知を出力部23に表示する。これにより、作業者は、行った操作によってエラーが解消したことを確認することができ、エラーの解消作業が終了する。
The work device 2 that has received the error resolution operation information from the management device 3 operates based on the received error resolution operation. As a result, the working device 2 attempts to eliminate the error that has occurred. As a result, when the error is resolved, the working device 2 transmits information to the effect that the error has been resolved (error resolution information) to the management device 3. The management device 3 transmits (transfers) the error resolution information to the remote monitoring device 4. When the remote operation control unit 21 of the remote monitoring device 4 receives the error resolution information from the management device 3, the output unit 23 displays a notification that the error has been resolved. As a result, the worker can confirm that the error has been resolved by the operation performed, and the error resolution work is completed.
一方、作業装置2は、管理装置3から受け取ったエラー解消操作の情報に基づいてエラーの解消を試みた結果、エラーが解消されなかった場合には、エラーが解消しなかった旨の情報(エラー未解消情報)を管理装置3に送信する。管理装置3は、エラー未解消情報をリモート監視装置4に送信(転送)する。リモート監視装置4のリモート操作制御部21は、管理装置3よりエラー未解消情報を受け取った場合には、エラーが未解消である旨の報知を出力部23に表示する。これにより、作業者は、行った操作によってはエラーが解消しなかったことを確認でき、新たなエラー解消操作の情報を管理装置3に送信することができる。また、作業者は、リモート操作ではエラーを解消できないと判断し、リモート操作によるエラー解消を断念した場合には、その旨の通知を管理装置3に送信して、エラー解消操作を終了することもできる。なお、この場合には、作業現場でのオペレータに連絡して手作業でエラーを解消する指示を与える等の処置を施すことになる。
On the other hand, if the error is not resolved as a result of the working device 2 trying to resolve the error based on the information of the error resolution operation received from the management device 3, the information indicating that the error is not resolved (error). Unresolved information) is transmitted to the management device 3. The management device 3 transmits (transfers) the error unresolved information to the remote monitoring device 4. When the remote operation control unit 21 of the remote monitoring device 4 receives the error unresolved information from the management device 3, the output unit 23 displays a notification that the error has not been resolved. As a result, the operator can confirm that the error has not been resolved by the operation performed, and can transmit the information of the new error resolution operation to the management device 3. Further, if the worker determines that the error cannot be resolved by the remote operation and gives up the error resolution by the remote operation, the worker may send a notification to that effect to the management device 3 and end the error resolution operation. can. In this case, measures such as contacting the operator at the work site and manually giving an instruction to eliminate the error will be taken.

The "in charge" of the master data item shown in FIG. 5 is the worker in charge of the error resolution operation, and is represented by the identification number assigned to each worker. In the example shown in FIG. 5, it is an example in which the three workers who work with the three remote monitoring devices 4 are set to "1", "2", and "3". Here, it is premised that each remote monitoring device 4 and a worker who works from each remote monitoring device 4 have a one-to-one relationship. When a plurality of workers also use one remote monitoring device 4, the worker inputs an identifier of the worker himself / herself from the input unit 22 before starting work on the remote monitoring device 4.

The "suction error" is an error including the fact that the component BH to be adsorbed by the nozzle 15N could not be adsorbed from the parts feeder 13, or the component BH that was adsorbed by the nozzle 15N was dropped. The "board recognition error" is an error in which after the board KB is positioned at the working position by the conveyor 12, an attempt is made to recognize the board KB by the board recognition camera 16, but the board KB cannot be recognized normally. Is. The "nozzle tip abnormality" is an error in which the tip portion of the nozzle 15N is bent.
図5に示すマスターデータの項目の「登録時刻」は、管理装置3が作業装置からエラー情報を受け取ってエラー情報を登録した時刻である。「開始時刻」は、管理装置3がエラー情報を送信した先のリモート監視装置4から、エラー情報に対する最初のエラー解消操作を受け取った時刻である。「終了時刻」は、管理装置3がエラー情報を送信した先のリモート監視装置4にエラー解消情報を送信したとき、あるいはリモート監視装置4からリモート操作によるエラー解消操作を断念した旨の情報を受け取った時刻である。「復旧」の項の「+」印は、エラーをリモート操作で解消できた(復旧できた)場合を示す識別子である。「非復旧」の項の「+」印は、エラーをリモート操作では解消できなかった(復旧できなかった)場合を示す識別子である。
The "registration time" of the master data item shown in FIG. 5 is the time when the management device 3 receives the error information from the work device and registers the error information. The "start time" is the time when the management device 3 receives the first error resolution operation for the error information from the remote monitoring device 4 to which the error information is transmitted. The "end time" is when the management device 3 sends the error resolution information to the remote monitoring device 4 to which the error information is sent, or when the remote monitoring device 4 receives the information that the error resolution operation by the remote operation is abandoned. It is the time. The "+" mark in the "recovery" section is an identifier indicating the case where the error can be resolved (recovered) by remote operation. The "+" mark in the "non-recovery" section is an identifier indicating the case where the error cannot be resolved (cannot be recovered) by remote operation.
演算部32は、マスターデータ作成部31によってマスターデータに作成されたデータに基づいて演算を行い、マスターデータにおける「操作時間」と「待ち時間」とに書き込みを行う。ここで、「操作時間」は、作業者がリモート監視装置4からエラー解消操作を行っていた時間であり、開始時刻から終了時刻まで間の時間に相当する。「待ち時間」は、エラー情報の登録があってからエラー解消操作が開始されるまでに要した時間であり、登録時刻から開始時刻までの間の時間に相当する。
The calculation unit 32 performs a calculation based on the data created in the master data by the master data creation unit 31, and writes in the "operation time" and the "waiting time" in the master data. Here, the "operation time" is the time during which the worker is performing the error resolution operation from the remote monitoring device 4, and corresponds to the time between the start time and the end time. The "waiting time" is the time required from the registration of the error information to the start of the error resolution operation, and corresponds to the time between the registration time and the start time.

The calculation unit 32 creates the "recovery information data" shown in FIG. 6A based on the master data and based on all the errors that occurred within the set period. The recovery information data shown in FIG. 6A has items of "total number of errors", "number of recovery errors", "number of non-recovery errors", "total operation time", and "total waiting time". Here, the "total number of errors" is the total number of errors that occurred within the period, and corresponds to the maximum number of "numbers" in the master data of FIG. The "recovery error number" is the total number of errors that can be resolved by remote operation, and corresponds to the total number of errors marked with "+" in the "recovery" item in the master data of FIG. The "number of non-recovery errors" is the total number of errors that could not be resolved by remote operation, and corresponds to the total number of errors marked with "+" in the "non-recovery" item in the master data of FIG.
図6Aに示す復旧情報データにおける「操作総時間」は、図5のマスターデータにおける「操作時間」の合計の時間である。従って、図5のマスターデータにおける操作時間の合計である「9:45:00(9時間45分0秒)」が、「操作総時間」に対応する。図6Aに示す復旧情報データにおける「待ち総時間」は、図5のマスターデータにおける「待ち時間」の合計の時間である。従って、図5のマスターデータにおける「待ち時間」の合計である「1:15:00(1時間15分0秒)」が、「待ち総時間」に対応する。
The "total operation time" in the recovery information data shown in FIG. 6A is the total time of the "operation time" in the master data of FIG. Therefore, "9:45:00 (9 hours 45 minutes 0 seconds)", which is the total operation time in the master data of FIG. 5, corresponds to the "total operation time". The "total waiting time" in the recovery information data shown in FIG. 6A is the total time of the "waiting time" in the master data of FIG. Therefore, "1: 15:00 (1 hour 15 minutes 0 seconds)", which is the total "waiting time" in the master data of FIG. 5, corresponds to the "total waiting time".
図4において、表示装置5には、表示操作部5Sが設けられている。リモート監視装置4に対する人員配置体制を管理する者(管理者)が表示操作部5Sから所定の操作を行うと、表示装置5に、図5に示す「マスターデータ」のほか、図6Aに示す「復旧情報データ」を表示させることができる。
In FIG. 4, the display device 5 is provided with a display operation unit 5S. When a person (administrator) who manages the personnel allocation system for the remote monitoring device 4 performs a predetermined operation from the display operation unit 5S, the display device 5 is displayed with the “master data” shown in FIG. 5 and the “master data” shown in FIG. 6A. "Recovery information data" can be displayed.
このように、本実施の形態におけるリモート操作システム1では、複数の作業装置2のいずれかに発生したエラーの情報を複数のリモート監視装置4のいずれかに送信し、エラーの情報の送信を受けたリモート監視装置4からエラーを解消するための操作(エラー解消操作)の情報をエラーが発生した作業装置2に送信することによって作業装置2に発生したエラーをリモートで解消できるように構成されている。そして、管理装置3は、或る期間内に複数の作業装置2に発生した全てのエラーについて、全てのエラーのそれぞれの発生からエラーのそれぞれについての最初のエラー解消操作が行われるまでの間の待ち時間の合計を算出する。表示装置5は、管理装置3が算出した待ち時間の合計を表示する。
As described above, in the remote operation system 1 in the present embodiment, the error information generated in any of the plurality of working devices 2 is transmitted to any of the plurality of remote monitoring devices 4, and the error information is transmitted. It is configured so that the error generated in the work device 2 can be remotely resolved by transmitting the information of the operation for resolving the error (error resolution operation) from the remote monitoring device 4 to the work device 2 in which the error occurred. There is. Then, for all the errors that have occurred in the plurality of working devices 2 within a certain period, the management device 3 is between the occurrence of each of the errors and the first error resolution operation for each of the errors. Calculate the total waiting time. The display device 5 displays the total waiting time calculated by the management device 3.
表示装置5に表示される復旧情報データ(図6A)の中の「待ち総時間」は、エラーの解消作業を行った作業者(識別番号「1」、「2」、「3」の3人の作業者)が、作業ライン2Lを構成する複数の作業装置2に発生したエラーに対して、期待された成果(エラーの解消)を発揮したかどうかを測るパラメータとして捉えることができる。具体的には、ある期間内についての待ち時間の合計の値が予め定められた基準時間よりも小さかった場合には、その期間内のエラー解消作業にあたった作業者は、人数的および能力的に十分であったと判断することができる。
The "total waiting time" in the recovery information data (FIG. 6A) displayed on the display device 5 is the three workers (identification numbers "1", "2", "3") who performed the error resolution work. The worker) can be regarded as a parameter for measuring whether or not the expected result (elimination of the error) is achieved with respect to the error generated in the plurality of work devices 2 constituting the work line 2L. Specifically, if the total value of the waiting time within a certain period is smaller than the predetermined reference time, the number of workers and the ability of the workers who performed the error resolution work within that period are sufficient. It can be judged that it was sufficient.
一方、「待ち総時間」の値が基準時間よりも大きかった場合には、エラー解消作業にあたった作業者は、人数的もしくは能力的に不十分であったと判断することができる。例えば図5の例において、基準時間が1時間30分に設定されていたとする。このとき、実際の待ち時間の合計はそれよりも短い1時間15分0秒であったことから、3人の作業者は、人数的および能力的に十分であり、リモート監視装置4における現状の人員配置体制を維持してよいと判断することができる。
On the other hand, if the value of "total waiting time" is larger than the reference time, it can be determined that the number of workers or the ability of the workers involved in the error resolution work is insufficient. For example, in the example of FIG. 5, it is assumed that the reference time is set to 1 hour and 30 minutes. At this time, since the total actual waiting time was 1 hour, 15 minutes, and 0 seconds, which was shorter than that, the three workers were sufficient in terms of number and ability, and the current state of the remote monitoring device 4 was sufficient. It can be judged that the staffing system may be maintained.
一方、基準時間が1時間に設定されていたとすると、実際の待ち時間の合計はそれよりも長かったことになる。このため、3人の作業者は、人数的もしくは能力的に不十分であり、現状のリモート監視装置4に対する人員配置体制を変える必要があると判断することができる。このため、作業装置2で発生したエラーの解消のためのリモート操作を行う作業者の配置又は人選等を行う管理者は、自身の経験又は勘等に頼ることなく(すなわち客観的に)、作業者の配置又は人選等を的確に行うことが可能である。
On the other hand, if the reference time was set to 1 hour, the total actual waiting time would be longer than that. Therefore, it can be determined that the three workers are insufficient in number or capacity, and it is necessary to change the staffing system for the current remote monitoring device 4. Therefore, the manager who assigns or selects a worker who performs a remote operation for resolving an error generated in the work device 2 works without relying on his / her own experience or intuition (that is, objectively). It is possible to accurately assign and select persons.
