　生産ラインにおいては、装置等のメンテナンスを行う作業、生産に必要な部材（材料）を供給（補充、交換）する作業、及び、生産工程において発生したトラブルに対応する作業等が発生する。生産ラインでは、作業者の人数に対して要求される作業の数が多い場合、作業者の対応が追いつかない場合がある。この場合、作業者に対して作業を指示することができないため、作業者が作業に対応できる状況となるまで、生産ラインを停止させなければならない。そのため、生産効率が低下する。また、生産ラインにおいて生産される製品が食品である場合、生産ラインが停止すると、食品が酸化する等して劣化する。この場合、食品を廃棄しなければならない。 In the production line, there are operations such as maintenance of devices, operations for supplying (replenishing and replacing) members (materials) necessary for production, operations for dealing with troubles occurring in the production process, and the like. In the production line, when the number of operations required for the number of workers is large, the workers may not be able to keep up. In this case, since the work cannot be instructed to the worker, the production line has to be stopped until the worker can handle the work. Therefore, production efficiency is reduced. Further, when the product produced in the production line is food, when the production line is stopped, the food is deteriorated due to oxidation or the like. In this case, the food must be discarded.
　本発明の一側面は、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる生産ラインの制御システムの提供を目的とする。 An object of the present invention is to provide a production line control system capable of stabilizing the quality of a production object while suppressing a decrease in production efficiency.
　本発明の一側面に係る生産ラインの制御システムは、複数の工程を含む生産ラインの制御システムであって、複数の工程のうちの少なくとも一部の工程において発生した作業の対応を要求する作業要求信号を受信する受信部と、受信部において受信した作業要求信号に基づいて、生産ラインに従事する作業者に作業を指示する情報を出力する制御部と、を備え、制御部は、生産ラインに対して現在設定される単位時間当たりの生産量を変更せずに、作業者に対して作業要求信号において要求される作業の処理を指示する第１のモードと、生産ラインに対して現在設定される単位時間当たりの生産量を少なく変更し、作業者に対して作業要求信号において要求される作業の処理を指示する第２のモードと、作業要求信号に基づいて選択的に切り替えて実行する。 A production line control system according to an aspect of the present invention is a production line control system including a plurality of processes, and requests work corresponding to work generated in at least some of the plurality of processes. A receiving unit that receives the signal, and a control unit that outputs information instructing work to an operator engaged in the production line based on the work request signal received by the receiving unit, and the control unit is connected to the production line. On the other hand, the first mode for instructing the worker to process the work required in the work request signal without changing the currently set production amount per unit time, and the currently set production line. The production amount per unit time is changed to be small, and the second mode for instructing the worker to perform the processing of the work required in the work request signal is selectively switched based on the work request signal. Instead to run.
　本発明の一側面に係る生産ラインの制御システムでは、制御部は、作業要求信号に基づいて、第１のモードと第２のモードとに選択的に切り替えて実行する。これにより、作業を処理できる作業者がいない場合であっても、第２のモードに切り替えることにより、生産ラインを停止させることなく、生産ラインを稼働し続けることができる。したがって、生産ラインの制御システムでは、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。また、製品が食品である場合、生産ラインが稼働し続けるため、生産ラインが完全に停止する場合に比べて、食品の劣化による食品の廃棄量を減少させることができる。その結果、生産ラインの制御システムでは、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。 In the production line control system according to one aspect of the present invention, the control unit selectively executes the first mode and the second mode based on the work request signal. Thereby, even if there is no worker who can process work, by switching to the second mode, the production line can be continuously operated without stopping the production line. Therefore, the production line control system can stabilize the quality of the production object while suppressing a decrease in production efficiency. In addition, when the product is food, the production line continues to operate, and therefore, the amount of food discarded due to food deterioration can be reduced compared to when the production line is completely stopped. As a result, the production line control system can stabilize the quality of the production object while suppressing a decrease in production efficiency.
　一実施形態においては、制御部は、作業者により作業要求信号において要求される作業の処理ができない場合、第２のモードに切り替えて実行してもよい。この構成では、作業を処理できる作業者がいない場合に、第２のモードに適切に切り替えることができる。 In one embodiment, the control unit may be switched to the second mode and executed when the work requested by the worker in the work request signal cannot be processed. In this configuration, when there is no worker who can process the work, it is possible to appropriately switch to the second mode.
　一実施形態においては、制御部は、作業者により作業要求信号において要求される作業の処理ができない場合、第２のモードに切り替えて実行してもよい。この構成では、作業を処理できる作業者の有無を適切に判断できる。 In one embodiment, the control unit may be switched to the second mode and executed when the work requested by the worker in the work request signal cannot be processed. In this configuration, it is possible to appropriately determine whether there is an operator who can process the work.
　一実施形態においては、作業者は、処理可能な作業が対応付けられており、制御部は、作業要求信号を受信した場合、作業者のうち現在設定可能な作業者に対応する処理可能な作業と、当該作業要求信号において要求される作業とを比較し、現在設定可能な作業者では作業が処理できない場合、第２のモードに切り替えて実行してもよい。この構成では、作業者に対して、当該作業者が対応することができない作業を指示しない。したがって、生産ラインの制御システムでは、作業者の能力に応じた作業の指示が可能となる。 In one embodiment, the worker is associated with a work that can be processed, and when the control unit receives a work request signal, the controllable work corresponding to the currently settable worker among the workers. And the work requested in the work request signal, and if the currently settable worker cannot process the work, it may be switched to the second mode and executed. In this configuration, an operation that cannot be handled by the worker is not instructed to the worker. Therefore, in the production line control system, it is possible to instruct work according to the ability of the worker.
　一実施形態においては、制御部は、第２のモードにおいて、単位時間当たりの生産量を、生産ラインにおける現在の生産状況に応じて、現在設定されている量よりも減少するように設定してもよい。この構成では、現在の生産状況に応じて生産量が減少するように設定するため、生産ラインの状況に応じた制御が可能となる。 In one embodiment, in the second mode, the control unit sets the production amount per unit time to be smaller than the currently set amount according to the current production status in the production line. Also good. In this configuration, since the production volume is set to decrease according to the current production status, control according to the production line status is possible.
　一実施形態においては、制御部は、第２のモードにおいて、単位時間当たりの生産量を、現在設定されている量よりも一定量だけ減少するように設定してもよい。この構成では、単位時間当たりの生産量を確実に減少させることができる。 In one embodiment, in the second mode, the control unit may set the production amount per unit time so as to decrease by a certain amount from the currently set amount. With this configuration, the production amount per unit time can be reliably reduced.
　一実施形態においては、制御部は、第２のモードにおいて、単位時間当たりの生産量を、作業者の作業状況に応じて、現在設定されている量よりも減少するように設定してもよい。この構成では、作業者の作業状況に応じて生産量を減少させるため、作業者の状況に応じた制御が可能となる。したがって、生産ラインの制御システムでは、作業者による作業が追いつかず、生産ラインが停止するという事態を確実に回避できる。 In one embodiment, in the second mode, the control unit may set the production amount per unit time to be smaller than the currently set amount according to the work status of the worker. . In this configuration, since the production amount is reduced according to the worker's work situation, control according to the worker's situation becomes possible. Therefore, in the production line control system, it is possible to reliably avoid a situation in which the work by the worker cannot catch up and the production line stops.
　一実施形態においては、生産ラインは複数設けられており、制御部は、第２のモードにおいて、一の生産ラインにおける単位時間当たりの生産量を現在設定されている量よりも減少するように設定した場合、他の生産ラインにおける単位時間当たりの生産量を現在設定されている量よりも増加するように設定してもよい。この構成では、一の生産ラインにおける生産量を減少させた場合であっても、他の生産ラインにおける生産量を増加させるため、全体としての生産量を維持することができる。したがって、生産ラインの制御システムでは、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。 In one embodiment, a plurality of production lines are provided, and the control unit sets the production amount per unit time in one production line to be smaller than the currently set amount in the second mode. In this case, the production amount per unit time in another production line may be set to be larger than the currently set amount. In this configuration, even when the production amount in one production line is decreased, the production amount in another production line is increased, and therefore the overall production amount can be maintained. Therefore, the production line control system can stabilize the quality of the production object while suppressing a decrease in production efficiency.
　本発明の一側面に係る生産ラインの制御システムは、複数の工程を含む生産ラインの制御システムであって、生産ラインは、外部から投入される物品を特定のフィルムを用いて包装する包装工程を少なくとも含み、包装工程においてフィルムの交換作業の対応を要求する作業要求信号を受信する受信部と、受信部において受信した作業要求信号に基づいて、生産ラインに従事する作業者にフィルムの交換作業を指示する情報を出力する制御部と、を備え、制御部は、包装工程に対して現在設定される単位時間当たりの包装個数を変更せずに、作業者に対して作業要求信号において要求されるフィルムの交換作業を指示する第１のモードと、包装工程に対して現在設定される単位時間当たりの包装個数を少なく変更し、作業者に対して作業要求信号において要求されるフィルムの交換作業を指示する第２のモードと、を作業要求信号から得られる交換作業数に基づいて選択的に切り替えて実行する。 A production line control system according to one aspect of the present invention is a production line control system including a plurality of processes, and the production line includes a packaging process for packaging an article to be input from the outside using a specific film. Including at least a receiving unit that receives a work request signal for requesting correspondence of a film changing operation in the packaging process, and a worker engaged in the production line performs a film changing operation based on the work request signal received by the receiving unit. A control unit that outputs information to be instructed, and the control unit is requested in the work request signal to the operator without changing the number of packages per unit time currently set for the packaging process. The first mode for instructing the film replacement operation and the number of packages per unit time that are currently set for the packaging process are changed to reduce the number of operations required for the operator. Selectively switching executed based and a second mode instructing the replacement of the required film, the replacement number obtained from the work request signal in the signal.
　本発明の一側面に係る生産ラインの制御システムでは、交換作業数に基づいて、第１のモードと第２のモードとに選択的に切り替えて実行する。これにより、フィルムの交換作業を処理できる作業者がいない場合であっても、第２のモードに切り替えることにより、生産ラインを停止させることなく、生産ラインを稼働し続けることができる。したがって、生産ラインの制御システムでは、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。また、製品が食品である場合、生産ラインが稼働し続けるため、生産ラインが完全に停止する場合に比べて、食品の劣化による食品の廃棄量を減少させることができる。その結果、生産ラインの制御システムでは、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。 In the production line control system according to one aspect of the present invention, the system is selectively switched between the first mode and the second mode based on the number of replacement operations. As a result, even if there is no worker who can handle the film replacement work, the production line can be continuously operated without stopping the production line by switching to the second mode. Therefore, the production line control system can stabilize the quality of the production object while suppressing a decrease in production efficiency. In addition, when the product is food, the production line continues to operate, and therefore, the amount of food discarded due to food deterioration can be reduced compared to when the production line is completely stopped. As a result, the production line control system can stabilize the quality of the production object while suppressing a decrease in production efficiency.
　本発明の一側面によれば、生産ラインにおける生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。 According to one aspect of the present invention, the quality of a production object can be stabilized while suppressing a decrease in production efficiency in a production line.

　以下、添付図面を参照して、本発明の好適な実施形態について詳細に説明する。なお、図面の説明において同一又は相当要素には同一符号を付し、重複する説明は省略する。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements will be denoted by the same reference numerals, and redundant description will be omitted.
　本実施形態に係る生産ラインの制御システム１は、図１に示される生産ライン１００を制御する。本実施形態では、生産ライン１００として、食品（菓子等）を生産するラインを一例として説明する。図１に示されるように、生産ライン１００は、主ラインＬと、主ラインＬから分岐する複数（ここでは３本）の分岐ラインＬ１，Ｌ２，Ｌ３を有する。主ラインＬには、工程Ｐが設けられる。工程Ｐにおいては、例えば、食品に処理が施される。工程Ｐにおいて処理された食品は、各分岐ラインＬ１～Ｌ３に搬送される。食品は、例えば、ベルトコンベアにより搬送される。なお、工程Ｐの前に更に工程があってもよい。 The production line control system 1 according to the present embodiment controls the production line 100 shown in FIG. In the present embodiment, a line for producing food (confectionery etc.) will be described as an example of the production line 100. As shown in FIG. 1, the production line 100 includes a main line L and a plurality of (here, three) branch lines L1, L2, and L3 branching from the main line L. The main line L is provided with a process P. In the process P, for example, the food is processed. The food processed in the process P is conveyed to the branch lines L1 to L3. The food is conveyed by, for example, a belt conveyor. There may be a further step before the step P.
　本実施形態では、分岐ラインＬ１～Ｌ３においては、同様の工程が行われる。分岐ラインＬ１は、例えば、複数（ここでは６個）の工程Ｐ１１～Ｐ１６を有する。工程Ｐ１１では、組合せ計量装置によって、食品を組合せ計量する。工程Ｐ１２（包装工程）では、包装装置によって、組合せ計量装置により計量された食品（外部から投入される物品）を特定のフィルムを用いて包装する。工程Ｐ１３では、包装検査装置によって、包装物の包装状態を検査する。例えば、工程Ｐ１３では、包装装置により包装された包装物を挟み込み、その反力を測定することで、包装物の内から外に空気漏れが発生しているか否かを検査する。工程Ｐ１４では、計量装置によって、食品の重量を検査する。工程Ｐ１５では、異物検査装置によって、異物混入の有無を検査する。工程Ｐ１６では、梱包装置によって、包装物を梱包する。分岐ラインＬ２，Ｌ３は、分岐ラインＬ１と同様に、複数の工程Ｐ２１～Ｐ２６，Ｐ３１～Ｐ３６を有する。 In this embodiment, the same process is performed in the branch lines L1 to L3. The branch line L1 includes, for example, a plurality of (here, six) processes P11 to P16. In the process P11, the combination weighing device is used to measure the combination food. In step P12 (packaging step), the food (weighed from the outside) weighed by the combination weighing device is packaged by a packaging device using a specific film. In step P13, the packaging state of the package is inspected by the packaging inspection device. For example, in the process P13, the package packaged by the packaging apparatus is sandwiched, and the reaction force is measured, thereby inspecting whether or not air leaks from the package package to the outside. In step P14, the weight of the food is inspected by the weighing device. In step P15, the presence or absence of foreign matter is inspected by the foreign matter inspection device. In step P16, the package is packed by the packing device. The branch lines L2 and L3 have a plurality of processes P21 to P26 and P31 to P36, similarly to the branch line L1.
　生産ライン１００においては、各工程に設けられる装置等のメンテナンスする作業、生産に必要な部材（材料）を供給（補充、交換）する作業、及び、生産工程において発生したトラブルに対応する作業等が発生する。例えば、工程Ｐ１２では、食品を包装するフィルムを交換する作業が発生する。各工程Ｐ，Ｐ１１～Ｐ１６，Ｐ２１～Ｐ２６，Ｐ３１～Ｐ３６設けられる装置は、作業が発生した場合、発生した作業の対応を要求する作業要求信号を生成し、作業要求信号を後述の受信部３に送信する。作業要求信号には、対応が必要な作業を特定する情報、作業が発生した工程（装置）を特定する情報、及び、作業（トラブル等）が発生した時間等が含まれ得る。各工程Ｐ，Ｐ１１～Ｐ１６，Ｐ２１～Ｐ２６，Ｐ３１～Ｐ３６設けられる装置は、作業要求信号を生成する生成部（図示省略）と、作業要求信号を送信する送信部（図示省略）と、を備える。例えば、工程Ｐ１２を構成する包装装置は、フィルムの交換作業の対応を要求する作業要求信号を生成部で生成し、当該作業要求信号を送信部で送信する。 In the production line 100, there are operations for maintenance of devices and the like provided in each process, operations for supplying (replenishing and replacing) members (materials) necessary for production, operations for dealing with troubles occurring in the production process, and the like. appear. For example, in the process P12, an operation for replacing a film for packaging food occurs. The apparatus provided in each process P, P11 to P16, P21 to P26, and P31 to P36 generates a work request signal for requesting correspondence of the generated work when the work is generated, and the work request signal is received by the receiving unit 3 described later. Send to. The work request signal may include information for identifying work that needs to be handled, information for identifying a process (device) in which the work has occurred, time when the work (trouble or the like) has occurred, and the like. An apparatus provided in each of the processes P, P11 to P16, P21 to P26, and P31 to P36 includes a generation unit (not shown) that generates a work request signal and a transmission unit (not shown) that transmits the work request signal. . For example, the packaging device that constitutes the process P12 generates a work request signal for requesting correspondence of the film replacement work by the generation unit, and transmits the work request signal by the transmission unit.
　図２に示されるように、生産ラインの制御システム１は、受信部３と、制御装置（制御部）５と、表示装置７と、を備える。 As shown in FIG. 2, the production line control system 1 includes a receiving unit 3, a control device (control unit) 5, and a display device 7.
　受信部３は、複数の工程Ｐ，Ｐ１１～Ｐ１６，Ｐ２１～Ｐ２６，Ｐ３１～Ｐ３６のうちの少なくとも一部の工程において発生した作業の対応を要求する作業要求信号を受信する。受信部３は、ケーブル等による有線で作業要求信号を受信してもよいし、無線で作業要求信号を受信してもよい。受信部３による受信を無線で行う場合、伝送媒体としては、電波、赤外線又は光を採用してもよい。受信部３は、受信した作業要求信号を制御装置５に出力する。 The receiving unit 3 receives a work request signal for requesting correspondence of work that has occurred in at least some of the processes P, P11 to P16, P21 to P26, and P31 to P36. The receiving unit 3 may receive the work request signal by a cable or the like, or may receive the work request signal wirelessly. When reception by the receiving unit 3 is performed wirelessly, radio waves, infrared rays, or light may be employed as the transmission medium. The receiving unit 3 outputs the received work request signal to the control device 5.
　制御装置５は、生産ライン１００を統括的に制御する。制御装置５は、生産ライン１００に設けられる各種装置のステータス情報及び稼働情報を管理する。制御装置５は、ＣＰＵ（Central　Processing　Unit）、ＲＯＭ（Read　Only　Memory）、ＲＡＭ（Random　Access　Memory）等で構成される。制御装置５は、制御システム１における各種制御処理を実行する概念的な部分を有する。概念的な部分は、例えばＲＯＭに格納されるプログラムがＲＡＭ上にロードされてＣＰＵで実行されるソフトウェアとして構成することができる。 The control device 5 controls the production line 100 in an integrated manner. The control device 5 manages status information and operation information of various devices provided in the production line 100. The control device 5 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The control device 5 has a conceptual part that executes various control processes in the control system 1. The conceptual part can be configured as software that is executed by the CPU after a program stored in the ROM is loaded onto the RAM, for example.
　制御装置５は、受信部３において受信した作業要求信号に基づいて、生産ライン１００に従事する作業者に対する作業を設定し、当該作業者に作業を指示する情報を出力する。例えば、制御装置５は、工程Ｐ１３の包装装置から送信されて受信部３において受信された作業要求信号に基づいて、フィルムの交換作業を指示する情報を出力する。 The control device 5 sets work for the worker engaged in the production line 100 based on the work request signal received by the receiving unit 3, and outputs information for instructing the worker to perform the work. For example, the control device 5 outputs information instructing the film replacement work based on the work request signal transmitted from the packaging device in the process P13 and received by the receiving unit 3.
　制御装置５は、受信部３から出力された作業要求信号を受け取ると、作業要求信号に基づいて、対応が必要な作業等を取得する。制御装置５は、作業に必要な作業者を設定する。作業者は、作業者ＤＢ（データベース）９に予め登録される。具体的には、図３に示されるように、作業者ＤＢ９には、Ｎｏ（ナンバー）と、作業者と、勤務状態と、作業状態と、が対応付けられて格納される。勤務状態は、例えば、作業者が出勤している（作業対応が可能な状態である）場合には「１」、作業者が出勤していない（作業対応が不可能な状態である）場合には「０」で示される。作業状態は、例えば、作業者が作業に対応している場合には「作業中」、作業者が作業に対応していない場合には「待機」で示される。 When the control device 5 receives the work request signal output from the receiving unit 3, the control device 5 acquires a work or the like that needs to be handled based on the work request signal. The control device 5 sets workers required for work. The worker is registered in advance in the worker DB (database) 9. Specifically, as shown in FIG. 3, No (number), an operator, a working state, and a working state are stored in association with each other in the worker DB 9. The work status is, for example, “1” when the worker is at work (a state in which work can be handled), or when the worker is not at work (in a state where work is not possible). Is indicated by “0”. For example, the work state is indicated as “working” when the worker is handling the work, and “standby” when the worker is not working.
　制御装置５は、第１のモードと、第２のモードと、を作業要求信号に基づいて選択的に切り替えて実行する。第１のモードは、生産ライン１００に対して現在設定される単位時間当たりの生産量を変更せずに、作業者に対して作業要求信号において要求される作業の処理を指示するモードである。第２のモードは、生産ライン１００に対して現在設定される単位時間当たりの生産量を少なく変更し、作業者に対して作業要求信号において要求される作業の処理を指示するモードである。 The control device 5 selectively switches between the first mode and the second mode based on the work request signal and executes it. The first mode is a mode for instructing the worker to perform work processing requested by the work request signal without changing the production amount per unit time currently set for the production line 100. The second mode is a mode in which the production amount per unit time currently set for the production line 100 is changed to be small, and the worker is instructed to perform work processing requested by the work request signal.
　制御装置５は、作業者ＤＢ９に予め登録される作業者のうち、作業の対応が可能な作業者がいるか否かを判断する。制御装置５は、作業者ＤＢ９を参照し、作業者の出勤状態が「１」であり、且つ、作業状態が「待機」である作業者がいる場合には、作業の対応が可能な作業者がいると判断する。制御装置５は、作業者ＤＢ９を参照し、作業者の出勤状態が「１」であり、且つ、作業状態が「作業中」である作業者のみである場合には、作業の対応が可能な作業者がいないと判断する。 The control device 5 determines whether there is a worker who can handle the work among the workers registered in advance in the worker DB 9. The control device 5 refers to the worker DB 9, and when there is a worker whose worker's attendance state is “1” and whose work state is “standby”, the worker who can handle the work. Judge that there is. The control device 5 refers to the worker DB 9, and when the worker's attendance state is “1” and only the worker whose work state is “working”, the work can be handled. Judge that there is no worker.
　制御装置５は、作業の対応が可能な作業者がいると判断した場合には、第の１モードを選択して実行する。制御装置５は、生産ライン１００に対して現在設定される単位時間当たりの生産量を変更せずに、作業者に作業の対応を指示する指示情報を生成する。指示情報には、作業が発生した工程、作業内容、及び、作業者を示す情報等が含まれる。制御装置５は、生成した指示情報を表示装置７に出力する。 The control device 5 selects and executes the first mode when it is determined that there is an operator who can handle the work. The control device 5 generates instruction information for instructing the worker to deal with work without changing the production amount per unit time currently set for the production line 100. The instruction information includes a process in which the work has occurred, work contents, information indicating the worker, and the like. The control device 5 outputs the generated instruction information to the display device 7.
　制御装置５は、作業の対応に可能な作業者がいないと判断した場合には、第２のモードを選択して実行する。制御装置５は、生産ライン１００に設定される単位時間当たりの生産量を、現在設定されている量よりも減少するように設定する。生産ライン１００の単位時間当たりの生産量は、例えば、作業者（責任者）によって任意に設定される。制御装置５は、単位時間当たりの生産量を、生産ライン１００における現在の生産状況に応じて、現在設定されている量よりも減少するように設定する。例えば、制御装置５は、現時点での生産ライン１００の生産量が予定の生産量よりも多い場合には、位時間当たりの生産量を基準量よりも多く減少させる。制御装置５は、現時点での生産ライン１００の生産量が予定の生産量よりも少ない場合には、位時間当たりの生産量を基準量よりも少なく減少させる。基準量は、予め設定される値であり、作業者により設定されてもよいし、自動で設定されてもよい。 The control device 5 selects and executes the second mode when it is determined that there is no worker capable of handling the work. The control device 5 sets the production amount per unit time set in the production line 100 so as to be smaller than the currently set amount. The production amount per unit time of the production line 100 is arbitrarily set by an operator (responsible person), for example. The control device 5 sets the production amount per unit time to be smaller than the currently set amount according to the current production status in the production line 100. For example, when the production amount of the production line 100 at the current time is larger than the scheduled production amount, the control device 5 reduces the production amount per unit time more than the reference amount. When the current production amount of the production line 100 is smaller than the planned production amount, the control device 5 reduces the production amount per unit time less than the reference amount. The reference amount is a value set in advance, and may be set by an operator or may be set automatically.
　例えば、図１に示される分岐ラインＬ１における工程Ｐ１２が包装装置で構成される場合、制御装置５は、この包装装置における単位時間当たりの処理個数を、現在設定される処理個数よりも少なく設定する。また、工程Ｐ１１が組合せ計量装置として構成され、この組合せ計量装置が包装装置と連動する場合、制御装置５が包装装置の処理個数を変更したタイミングと連動し、組合せ計量装置における処理個数も変更される。 For example, when the process P12 in the branch line L1 shown in FIG. 1 is configured by a packaging device, the control device 5 sets the processing number per unit time in the packaging device to be smaller than the currently set processing number. . Further, when the process P11 is configured as a combination weighing device and this combination weighing device is linked with the packaging device, the number of processing in the combination weighing device is also changed in conjunction with the timing when the control device 5 changes the number of processing of the packaging device. The
　本実施形態では、制御装置５は、作業が分岐ラインＬ１～Ｌ３のいずれかにおいて発生した場合には、作業が発生した分岐ラインＬ１～Ｌ３において設定される単位時間当たりの生産量を、現在設定されている量よりも減少するように設定する。制御装置５は、一の分岐ラインにおける単位時間当たりの生産量を現在設定されている量よりも減少するように設定した場合、他の分岐ラインにおける単位時間当たりの生産量を現在設定されている量よりも増加するように設定する。例えば、制御装置５は、分岐ラインＬ１における単位時間当たりの生産量を減少させる場合には、分岐ラインＬ２，Ｌ３における単位時間当たりの生産量を増加させる。 In the present embodiment, when the work occurs in any of the branch lines L1 to L3, the control device 5 currently sets the production amount per unit time set in the branch lines L1 to L3 where the work has occurred. Set to be less than the amount that is being used. When the control unit 5 sets the production amount per unit time in one branch line to be smaller than the currently set amount, the production amount per unit time in the other branch line is currently set. Set to increase over quantity. For example, when reducing the production amount per unit time in the branch line L1, the control device 5 increases the production amount per unit time in the branch lines L2 and L3.
　制御装置５は、作業の対応に可能な作業者がいないと判断した場合には、現在行われている作業の進捗状況を取得する。具体的には、本実施形態では、制御装置５は、作業者が対応している作業に要する作業時間を取得する。作業時間は、作業ＤＢ１１に予め登録されている。具体的には、図４に示されるように、作業ＤＢ１１には、「工程」と、工程において発生し得る「作業」と、当該作業の「作業時間」と、が対応付けられて格納される。作業時間は、例えば、過去の作業実績に基づいて設定される。 When it is determined that there is no worker who can handle the work, the control device 5 acquires the progress status of the work currently being performed. Specifically, in the present embodiment, the control device 5 acquires the work time required for the work that the worker is handling. The work time is registered in advance in the work DB 11. Specifically, as illustrated in FIG. 4, the work DB 11 stores “process”, “work” that can be generated in the process, and “work time” of the work in association with each other. . The work time is set based on, for example, past work results.
　制御装置５は、作業ＤＢ１１を参照し、作業に応じた作業時間を取得する。なお、制御装置５は、作業者の習熟度（経験年数等）に基づいて、作業時間を設定してもよい。詳細には、制御装置５は、例えば、作業ＤＢ１１から取得した作業時間が「１５ｍｉｎ」である場合において、現在作業を行っている作業者の習熟度が高い場合には、作業時間を「１０ｍｉｎ」に設定する。すなわち、制御装置５は、作業者の習熟度が高い場合には、作業に要する作業時間を短くする。また、制御装置５は、作業者の習熟度が低い場合には、作業時間を長くしてもよい。習熟度は、例えば、作業者毎に予め設定される。 The control device 5 refers to the work DB 11 and acquires the work time according to the work. In addition, the control apparatus 5 may set work time based on a worker's proficiency level (experience years etc.). Specifically, for example, when the work time acquired from the work DB 11 is “15 min”, the control device 5 sets the work time to “10 min” when the skill level of the worker who is currently working is high. Set to. That is, the control device 5 shortens the work time required for the work when the skill level of the worker is high. Moreover, the control apparatus 5 may lengthen work time, when a worker's proficiency level is low. The proficiency level is set in advance for each worker, for example.
　制御装置５は、作業時間を取得すると、作業者が作業を開始した時間に基づいて、作業の進捗状況を取得する。作業者が作業を開始した時間は、種々の方法により取得し得る。例えば、作業を開始した時間は、作業者が装置において作業を開始したときに装置から自動的に送信されてもよいし、作業者の操作により送信されてもよい。 When the control device 5 acquires the work time, the control device 5 acquires the progress of the work based on the time when the worker started the work. The time when the worker starts work can be obtained by various methods. For example, the time when the work is started may be automatically transmitted from the apparatus when the worker starts the work in the apparatus, or may be transmitted by the operation of the worker.
　制御装置５は、作業時間及び作業開始時間に基づいて、作業の残り時間を算出する。具体的には、制御装置５は、以下の式に基づいて、作業の残り時間を算出する。
作業の残り時間＝作業時間－（現在の時間－作業開始時間）
　制御装置５は、作業の残り時間を算出することにより、作業の進捗状況を取得する。制御装置５は、作業の進捗状況に基づいて、作業の終了時間を算出する。なお、作業の終了時間には、作業者が、表示装置７において次の作業の指示を確認し得る位置まで移動する時間も含まれる。移動時間は、作業を行っていた位置から表示装置７が配置される位置までの平均的な移動時間に基づいて設定されてよいし、作業者の位置を特定し得る情報（ＧＰＳ情報、ＲＦＩＤによる情報等）に基づいて設定されてもよい。 The control device 5 calculates the remaining work time based on the work time and the work start time. Specifically, the control device 5 calculates the remaining work time based on the following equation.
Remaining work time = work time-(current time-work start time)
The control device 5 acquires the progress status of the work by calculating the remaining time of the work. The control device 5 calculates the work end time based on the progress of the work. Note that the work end time includes a time during which the worker moves to a position where the display device 7 can confirm the next work instruction. The movement time may be set based on an average movement time from the position where the work was performed to the position where the display device 7 is arranged, or information (GPS information or RFID) that can specify the position of the worker. Information) and the like.
　制御装置５は、作業の終了時間を算出すると、生産ライン１００の生産量を再設定する。制御装置５は、作業の終了時間となった場合に、減少するように設定されている生産ライン１００の単位時間当たりの生産量を再設定する。具体的には、制御装置５は、例えば、生産ライン１００に設定されている単位時間当たりの生産量を、元の生産量（生産開始時の生産量等）に設定する。なお、制御装置５は、生産ライン１００に設定されている単位時間当たりの生産量を、元の生産量よりも増加させてもよい。なお、作業の終了時間は、他の方法により得られてもよい。例えば、作業の終了時間は、作業が終了したときに装置から自動で送信されてもよいし、作業者の操作により送信されてもよい。 The controller 5 resets the production amount of the production line 100 after calculating the work end time. The control device 5 resets the production amount per unit time of the production line 100 set so as to decrease when the work end time is reached. Specifically, for example, the control device 5 sets the production amount per unit time set in the production line 100 to the original production amount (production amount at the start of production, etc.). Note that the control device 5 may increase the production amount per unit time set in the production line 100 more than the original production amount. The work end time may be obtained by other methods. For example, the work end time may be automatically transmitted from the apparatus when the work is completed, or may be transmitted by an operator's operation.
　制御装置５は、作業の終了時間を算出すると、作業が終了する作業者に作業の対応を指示する指示情報を生成する。制御装置５は、生成した指示情報を表示装置７に出力する。 When calculating the end time of the work, the control device 5 generates instruction information for instructing the worker who finishes the work to deal with the work. The control device 5 outputs the generated instruction information to the display device 7.
　表示装置７は、制御装置５から出力された指示情報に基づき表示する。表示装置７は、例えば、ディスプレイ（モニタ）である。表示装置７は、生産ライン１００において一又は複数設けられる。表示装置７は、作業者が視認可能な位置に配置される。 The display device 7 displays based on the instruction information output from the control device 5. The display device 7 is a display (monitor), for example. One or more display devices 7 are provided in the production line 100. The display device 7 is arranged at a position that can be visually recognized by the operator.
　続いて、生産ラインの制御システム１の動作について、図５を参照して説明する。各ラインＬ，Ｌ１～Ｌ３の各工程Ｐ，Ｐ１１～Ｐ１６，Ｐ２１～Ｐ２６，Ｐ３１～Ｐ３６は、作業が発生した場合、作業の対応を要求する作業要求信号を送信する。 Next, the operation of the production line control system 1 will be described with reference to FIG. Each process P, P11 to P16, P21 to P26, and P31 to P36 of each line L, L1 to L3 transmits a work request signal for requesting work correspondence when work occurs.
　図５に示されるように、受信部３は、工程Ｐ，Ｐ１１～Ｐ１６，Ｐ２１～Ｐ２６，Ｐ３１～Ｐ３６から送信された作業要求信号を受信する（ステップＳ０１）。次に、制御装置５は、作業者要求信号に基づいて作業を取得する（ステップＳ０２）。続いて、制御装置５は、作業できる作業者がいるか否かを判断する（ステップＳ０３）。制御装置５は、作業要求信号に基づいて、第１のモードと第２のモードとを選択的に切り替えて実行する。 As shown in FIG. 5, the receiving unit 3 receives the work request signals transmitted from the processes P, P11 to P16, P21 to P26, and P31 to P36 (step S01). Next, the control device 5 acquires work based on the worker request signal (step S02). Subsequently, the control device 5 determines whether or not there is an operator who can work (step S03). Based on the work request signal, the control device 5 selectively switches between the first mode and the second mode for execution.
　例えば、制御装置５は、作業要求信号から得られるフィルムの交換作業数に基づいて、第１のモードと、第２のモードと、を選択的に切り替えて実行する。この場合、第１のモードでは、工程Ｐ１２に対して現在設定される単位時間当たりの包装個数を変更せずに、作業者に対して作業要求信号において要求されるフィルムの交換作業を指示する。第２のモードでは、工程Ｐ１２に対して現在設定される単位時間当たりの包装個数を少なく変更し、作業者に対して作業要求信号において要求されるフィルムの交換作業を指示する。 For example, the control device 5 selectively switches between the first mode and the second mode based on the number of film replacement operations obtained from the operation request signal. In this case, in the first mode, without changing the number of packages per unit time currently set for the process P12, the operator is instructed to replace the film required in the work request signal. In the second mode, the number of packages per unit time that is currently set for the process P12 is changed to be small, and the operator is instructed to replace the film required in the work request signal.
　制御装置５は、作業できる作業者がいると判断した場合（ステップＳ０３：ＹＥＳ）には、ステップＳ０４に進む。すなわち、制御装置５は、第１のモードを選択して実行する。制御装置５は、作業できる作業者がいないと判断した場合（ステップＳ０３：ＮＯ）には、ステップＳ０７に進む。すなわち、制御装置５は、第２のモードを選択して実行する。 When the control device 5 determines that there is an operator who can work (step S03: YES), the control device 5 proceeds to step S04. That is, the control device 5 selects and executes the first mode. When the control device 5 determines that there is no worker who can work (step S03: NO), the control device 5 proceeds to step S07. That is, the control device 5 selects and executes the second mode.
　ステップＳ０４では、制御装置５は、作業できる作業者を決定する。制御装置５は、作業者を決定すると、当該作業者に作業を指示する指示情報を生成し、指示情報を表示装置７に出力する（ステップＳ０５）。すなわち、制御装置５は、生産ライン１００に対して現在設定される単位時間当たりの生産量を変更せずに、指示情報を出力する。表示装置７は、制御装置５から出力された指示情報を受け取ると、作業指示を表示する（ステップＳ０６）。 In step S04, the control device 5 determines a worker who can work. When determining the worker, the control device 5 generates instruction information for instructing the worker to perform work, and outputs the instruction information to the display device 7 (step S05). That is, the control device 5 outputs the instruction information without changing the production amount per unit time currently set for the production line 100. Upon receiving the instruction information output from the control device 5, the display device 7 displays a work instruction (Step S06).
　図６に示されるように、表示装置７には、例えば、「ラインの状態」と、「作業」と、が表示される。ラインの状態には、例えば、「ラインＮｏ」と、ラインの「状態」と、「作業発生までの時間」と、「作業有無」と、が対応して表示される。図６に示される例では、「ラインＮｏ」において、主ラインＬは「１」、分岐ラインＬ１は「２」、分岐ラインＬ２は「３」、分岐ラインＬ３は「４」で示される。図６では、ラインＮｏ２（分岐ラインＬ１）において作業が発生していることを示している。 As shown in FIG. 6, for example, “line state” and “work” are displayed on the display device 7. For example, “line No”, “state” of the line, “time until work occurrence”, and “work presence / absence” are displayed in correspondence with the line status. In the example shown in FIG. 6, in “Line No”, the main line L is indicated by “1”, the branch line L1 is indicated by “2”, the branch line L2 is indicated by “3”, and the branch line L3 is indicated by “4”. FIG. 6 shows that work is occurring in line No. 2 (branch line L1).
　作業には、「ラインＮｏ」と、「作業」と、「作業者」と、が対応して表示される。図６に示す例では、ラインＮｏ２においてフィルム交換の作業が発生しており、作業者「０００３」に作業の対応を指示することを示している。作業者を示す数字は、作業者ＤＢ９において作業者と対応付けられている数字に対応する。なお、表示装置７における「作業」の欄には、作業の優先度に基づいて、作業が発生していないラインに発生する作業が表示されてもよい。作業の優先度は、作業発生までの時間に基づいて設定される。 In the work, “Line No”, “Work”, and “Worker” are displayed correspondingly. In the example shown in FIG. 6, the film replacement work has occurred in the line No 2, and the worker “0003” is instructed to deal with the work. The number indicating the worker corresponds to the number associated with the worker in the worker DB 9. In the column of “work” on the display device 7, work that occurs on a line where no work has occurred may be displayed based on the priority of the work. The priority of the work is set based on the time until the work occurs.
　図５に示されるように、ステップＳ０７では、制御装置５は、生産量を設定する。制御装置５は、生産ライン１００に設定される単位時間当たりの生産量を、現在設定されている量よりも減少するように設定する。例えば、制御装置５は、工程Ｐ１２の包装装置における単位時間当たりの処理個数を、現在設定される処理個数よりも少なく設定する。続いて、制御装置５は、作業の進捗状況を取得する（ステップＳ０８）。制御装置５は、作業の進捗状況に基づいて作業の終了時間を取得し、終了時間に合わせて生産量を再設定する（ステップＳ０９）。その後、制御装置５は、作業者を決定し（ステップＳ０４）、指示情報を出力する（ステップＳ０５）。 As shown in FIG. 5, in step S07, the control device 5 sets the production amount. The control device 5 sets the production amount per unit time set in the production line 100 so as to be smaller than the currently set amount. For example, the control device 5 sets the processing number per unit time in the packaging device in the process P12 to be smaller than the currently set processing number. Subsequently, the control device 5 acquires the progress status of the work (step S08). The control device 5 acquires the end time of the work based on the progress of the work, and resets the production amount according to the end time (step S09). Thereafter, the control device 5 determines an operator (step S04) and outputs instruction information (step S05).
　以上説明したように、本実施形態係る生産ラインの制御システム１では、制御装置５は、作業要求信号に基づいて、第１のモードと第２のモードとに選択的に切り替えて実行する。第２のモードでは、作業者により、作業要求信号において要求される作業の処理ができない場合、生産ライン１００に設定される単位時間当たりの生産量を、現在設定されている量よりも減少するように設定する。これにより、作業を処理できる作業者がいない場合であっても、生産ライン１００を停止させることなく、生産ライン１００を稼働し続けることができる。したがって、生産ラインの制御システム１では、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。また、本実施形態のように、生産ライン１００において生産される製品が食品である場合、生産ライン１００が稼働し続けるため、生産ライン１００が完全に停止する場合に比べて、食品の劣化による食品の廃棄量を減少させることができる。その結果、生産ラインの制御システム１では、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。 As described above, in the production line control system 1 according to this embodiment, the control device 5 selectively executes the first mode and the second mode based on the work request signal. In the second mode, when the worker cannot process the work requested in the work request signal, the production amount per unit time set in the production line 100 is reduced from the currently set amount. Set to. Thereby, even if there is no worker who can process work, the production line 100 can be continuously operated without stopping the production line 100. Therefore, the production line control system 1 can stabilize the quality of the production object while suppressing a decrease in production efficiency. In addition, when the product produced in the production line 100 is food as in the present embodiment, the production line 100 continues to operate, and therefore, the food due to the deterioration of the food compared to the case where the production line 100 is completely stopped. The amount of waste can be reduced. As a result, the production line control system 1 can stabilize the quality of the production object while suppressing a decrease in production efficiency.
　本実施形態に係る生産ラインの制御システム１では、制御装置５は、第２のモードにおいて、位時間当たりの生産量を、生産ライン１００における現在の生産状況に応じて、現在設定されている量よりも減少するように設定する。この構成では、現在の生産状況に応じて生産量が減少するように設定するため、生産ライン１００の状況に応じた制御が可能となる。 In the production line control system 1 according to the present embodiment, in the second mode, the control device 5 sets the production amount per unit time in accordance with the current production status in the production line 100. Is set to decrease. In this configuration, since the production volume is set to decrease according to the current production status, control according to the status of the production line 100 is possible.
　本実施形態に係る生産ラインの制御システム１では、生産ライン１００には、複数の分岐ラインＬ１～Ｌ３が設けられている。制御装置５は、一の分岐ラインにおける単位時間当たりの生産量を現在設定されている量よりも減少するように設定した場合、他の分岐ラインにおける単位時間当たりの生産量を現在設定されている量よりも増加するように設定する。この構成では、一の分岐ラインにおける生産量を減少させた場合であっても、他の分岐ラインにおける生産量を増加させるため、全体としての生産量を維持することができる。したがって、生産ラインの制御システム１では、生産効率の低下を抑制しながら、生産対象物の品質を安定化できる。 In the production line control system 1 according to the present embodiment, the production line 100 is provided with a plurality of branch lines L1 to L3. When the control unit 5 sets the production amount per unit time in one branch line to be smaller than the currently set amount, the production amount per unit time in the other branch line is currently set. Set to increase over quantity. In this configuration, even when the production amount in one branch line is decreased, the production amount in the other branch line is increased, so that the overall production amount can be maintained. Therefore, the production line control system 1 can stabilize the quality of the production object while suppressing a decrease in production efficiency.
　以上、本発明の実施形態について説明してきたが、本発明は必ずしも上述した実施形態に限定されるものではなく、その要旨を逸脱しない範囲で様々な変更が可能である。 As mentioned above, although embodiment of this invention has been described, this invention is not necessarily limited to embodiment mentioned above, A various change is possible in the range which does not deviate from the summary.
　上記実施形態では、生産ライン１００が複数のラインＬ，Ｌ１～Ｌ３を有する形態を一例に説明した。しかし、生産ラインの形態はこれに限定されない。例えば、生産ラインは、１本であってもよい。 In the above embodiment, an example in which the production line 100 has a plurality of lines L, L1 to L3 has been described. However, the form of the production line is not limited to this. For example, the number of production lines may be one.
　上記実施形態では、受信部３及び制御装置５を別個に備える形態を一例に説明した。しかし、受信部３及び制御装置５は、１つの装置により構成されていてもよい。 In the above embodiment, an example in which the receiving unit 3 and the control device 5 are separately provided has been described. However, the receiving unit 3 and the control device 5 may be configured by a single device.
　上記実施形態では、表示装置７がディスプレイである形態を一例に説明した。しかし、表示装置７は、例えば、携帯端末等であってもよい。 In the above embodiment, an example in which the display device 7 is a display has been described. However, the display device 7 may be, for example, a mobile terminal.
　上記実施形態では、作業者ＤＢ９及び作業ＤＢ１１を有する形態を一例に説明した。しかし、作業者ＤＢ９及び作業ＤＢ１１は１つのデータベースにより構成されていてもよい。また、作業者ＤＢ９及び作業ＤＢ１１は、制御装置５が有する構成であってもよい。 In the above embodiment, an example in which the worker DB 9 and the work DB 11 are provided has been described. However, the worker DB 9 and the work DB 11 may be configured by one database. Moreover, the structure which the control apparatus 5 has may be sufficient as worker DB9 and work DB11.
　上記実施形態では、制御装置５が、第２のモードにおいて、単位時間当たりの生産量を、生産ライン１００における現在の生産状況に応じて、現在設定されている量よりも減少するように設定する形態を一例に説明した。しかし、制御装置５は、単位時間当たりの生産量を、現在設定されている量よりも一定量だけ減少するように設定してもよい。一定量は、任意に設定される。この構成では、単位時間当たりの生産量を確実に減少させることができる。 In the above embodiment, in the second mode, the control device 5 sets the production amount per unit time to be smaller than the currently set amount according to the current production status in the production line 100. The form has been described as an example. However, the control device 5 may set the production amount per unit time so as to decrease by a certain amount from the currently set amount. A certain amount is arbitrarily set. With this configuration, the production amount per unit time can be reliably reduced.
　また、制御装置５は、第２のモードにおいて、単位時間当たりの生産量を、作業者の作業状況に応じて、現在設定されている量よりも減少するように設定してもよい。詳細には、制御装置５は、例えば、作業者の進捗状況において作業の残り時間が長い場合には、単位時間当たりの生産量を基準量よりも多く減少させる。制御装置５は、例えば、作業者の進捗状況において作業の残り時間が短い場合には、単位時間当たりの生産量を基準量よりも少なく減少させる。この構成では、作業者の作業状況に応じて生産量を減少させるため、作業者の状況に応じた制御が可能となる。したがって、作業者による作業が追いつかず、生産ライン１００が停止するという事態を確実に回避できる。 Further, in the second mode, the control device 5 may set the production amount per unit time to be smaller than the currently set amount according to the work status of the worker. Specifically, for example, when the remaining work time is long in the progress status of the worker, the control device 5 reduces the production amount per unit time more than the reference amount. For example, when the remaining work time is short in the progress status of the worker, the control device 5 reduces the production amount per unit time to be smaller than the reference amount. In this configuration, since the production amount is reduced according to the worker's work situation, control according to the worker's situation becomes possible. Therefore, it is possible to reliably avoid the situation where the work by the worker cannot catch up and the production line 100 stops.
　上記実施形態では、生産ライン１００が、主ラインＬ及び主ラインＬから分岐する複数の分岐ラインＬ１～Ｌ３が設けられている形態を一例に説明した。しかし、生産ラインは、独立する複数ラインが設けられていてもよい。 In the above-described embodiment, the configuration in which the production line 100 is provided with the main line L and a plurality of branch lines L1 to L3 branching from the main line L has been described as an example. However, the production line may be provided with a plurality of independent lines.
　上記実施形態では、作業者ＤＢ９には、Ｎｏ（ナンバー）と、作業者と、勤務状態と、作業状態と、が対応付けられて格納される形態を一例に説明した。しかし、作業者ＤＢには、処理可能な作業が更に対応付けられて格納されていてもよい。つまり、作業者の能力において処理することができる作業が対応付けられていてもよい。この構成の場合、制御装置５は、作業者ＤＢ９を参照し、作業者の出勤状態が「１」であり、且つ作業状態が「待機」である作業者を抽出する。制御装置５は、作業者ＤＢ９を参照し、抽出した現在設定可能な作業者が処理可能な作業と、作業要求信号において要求される作業とを比較する。制御装置５は、現在設定可能な作業者が作業要求信号において要求される作業を処理可能である場合には、作業の対応が可能な作業者がいると判断する。制御装置５は、現在設定可能な作業者が作業要求信号において要求される作業を処理できない場合には、作業の対応が可能な作業者がいない判断する。この構成では、作業者に対して、当該作業者が対応することができない作業を指示しない。したがって、作業者の能力に応じた作業の指示が可能となる。 In the above-described embodiment, an example has been described in which the worker DB 9 stores No (number), the worker, the working state, and the working state in association with each other. However, a work that can be processed may be stored in the worker DB in association with the work DB. That is, work that can be processed in the ability of the worker may be associated. In the case of this configuration, the control device 5 refers to the worker DB 9 and extracts workers whose work status is “1” and whose work status is “standby”. The control device 5 refers to the worker DB 9 and compares the extracted work that can be processed by the currently settable worker with the work requested in the work request signal. When the currently settable worker can process the work requested in the work request signal, the control device 5 determines that there is a worker who can handle the work. When the currently settable worker cannot process the requested work in the work request signal, the control device 5 determines that there is no worker who can handle the work. In this configuration, an operation that cannot be handled by the worker is not instructed to the worker. Therefore, it is possible to instruct work according to the ability of the worker.

          A production line control system including a plurality of processes,
    The production line includes at least a packaging process for packaging an externally charged article using a specific film,
    A receiving unit for receiving a work request signal for requesting correspondence of the film exchange work in the packaging step;
    Based on the work request signal received in the receiving unit, a control unit that outputs information instructing the worker engaged in the production line to replace the film, and
    The controller is
    A first mode for instructing the operator to change the film required in the operation request signal without changing the number of packages per unit time currently set for the packaging process;
    A second mode in which the number of packages per unit time currently set for the packaging process is changed to be small, and the operator is instructed to replace the film required in the work request signal;
    Is a production line control system that selectively performs switching based on the number of replacement works obtained from the work request signal.
