Abstract

PROBLEM TO BE SOLVED: To improve productivity by effectively utilizing a production facility in which a plurality of component mounting lines are juxtaposed.SOLUTION: Between a halfway portion of one component mounting line and a halfway portion of another component mounting line among a plurality of component mounting lines, a bypass conveyor 11 for conveying a circuit substrate between both component mounting lines is installed and a bypass mounting line connected from the halfway portion of the one component mounting line to the halfway portion of the other component mounting line via the bypass conveyor 11 is constructed. A production management computer selects a production pattern from a normal production pattern producing component mounting substrates in each component mounting line and a bypass production pattern producing component mounting substrates in the bypass mounting line.

Description

本発明は、複数本の部品実装ラインの生産を管理する部品実装ラインの生産管理装置及び生産管理方法に関する発明である。   The present invention relates to a production management apparatus and production management method for a component mounting line that manages the production of a plurality of component mounting lines.

一般に、部品実装基板を生産する工場では、回路基板への半田印刷、部品の装着等を行う複数台の装置を配列した部品実装ラインを複数本並設し、各部品実装ライン毎にそれぞれ部品実装基板を生産するようにしている。   Generally, in factories that produce component mounting boards, multiple component mounting lines are arranged side by side, and multiple component mounting lines are arranged in parallel, and each component mounting line is mounted individually. We are trying to produce substrates.

このような複数本の部品実装ラインの生産を管理するシステムでは、特許文献１（特開２００９−９９７７６号公報）に記載されているように、１本の部品実装ラインのみで部品実装基板を生産可能か否かを判定し、１本の部品実装ラインのみでは部品実装基板を生産できないと判断した場合には、当該部品実装ラインの出口から排出される生産途中の回路基板を他の部品実装ラインの入口に投入するように２本以上の部品実装ラインの出口と入口をつなぎ合わせることで、１本の部品実装ラインのみでは生産できない部品実装基板を２本以上の部品実装ラインで生産することが提案されている。   In such a system for managing the production of a plurality of component mounting lines, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2009-99776), a component mounting board is produced by only one component mounting line. If it is determined whether or not it is possible to produce a component mounting board with only one component mounting line, the circuit board in the middle of production discharged from the outlet of the component mounting line is replaced with another component mounting line. By connecting the outlets and inlets of two or more component mounting lines so that they can be fed into the inlet of the component, it is possible to produce component mounting boards that cannot be produced with only one component mounting line with two or more component mounting lines. Proposed.

特開２００９−９９７７６号公報JP 2009-99776 A

上記特許文献１では、１本の部品実装ラインのみでは部品実装基板を生産できないと判断した場合に、２本以上の部品実装ラインの出口と入口をつなぎ合わせて、回路基板を当該２本以上の部品実装ラインの全ての装置を通過させるようになっているが、各部品実装ラインには同種の装置が重複して存在するため、各部品実装ライン間で重複する一部の装置（例えば印刷機、リフロー炉）を重複して使用しなくても、部品実装基板を生産できる場合がある。この場合は、使用しない装置にも回路基板を搬送することになるため、回路基板の搬送経路が長くなって、その分、サイクルタイムが長くなり、生産性が低下する欠点がある。   In Patent Document 1, when it is determined that a component mounting board cannot be produced with only one component mounting line, the outlets and inlets of two or more component mounting lines are joined together to connect the two or more circuit boards. Although all the devices on the component mounting line are allowed to pass through, there are duplicate devices of the same type on each component mounting line, so some of the devices that overlap between the component mounting lines (for example, a printing machine) In some cases, it is possible to produce a component-mounted board without using multiple reflow furnaces. In this case, since the circuit board is also transferred to a device that is not used, the circuit board transfer path becomes longer, and the cycle time becomes longer correspondingly, resulting in a disadvantage that productivity is lowered.

また、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止すると、当該部品実装ラインの生産が停止してしまい、部品実装ラインの稼働率が低下して生産性が低下する欠点がある。   In addition, if a part of one of the component mounting lines fails or stops due to an error, the production of the component mounting line stops, and the operating rate of the component mounting line decreases, resulting in a decrease in productivity. There is.

そこで、本発明が解決しようとする課題は、複数本の部品実装ラインを並設した生産設備を有効に活用して生産性を向上できる部品実装ラインの生産管理装置及び生産管理方法を提供することである。   Therefore, the problem to be solved by the present invention is to provide a production management apparatus and production management method for a component mounting line that can improve productivity by effectively using a production facility in which a plurality of component mounting lines are arranged in parallel. It is.

上記課題を解決するために、請求項１に係る発明は、複数台の装置を配列した部品実装ラインを複数本並設し、複数本の部品実装ラインの生産を管理する生産管理コンピュータを備えた部品実装ラインの生産管理装置において、前記複数本の部品実装ラインのうちの一方の部品実装ラインの途中と他方の部品実装ラインの途中との間に、両部品実装ライン間で回路基板を搬送するバイパス搬送装置を設置して、前記一方の部品実装ラインの途中から前記バイパス搬送装置を介して前記他方の部品実装ラインの途中につながるパイパス実装ラインを構築し、前記生産管理コンピュータは、各部品実装ライン毎にそれぞれ部品実装基板を生産する通常生産パターンと、前記パイパス実装ラインで部品実装基板を生産するパイパス生産パターンの中から各部品実装ラインの生産パターンを選択するようにしたものである。   In order to solve the above-mentioned problem, the invention according to claim 1 includes a production management computer that manages a plurality of component mounting lines by arranging a plurality of component mounting lines in which a plurality of devices are arranged side by side. In the production management apparatus for a component mounting line, the circuit board is transported between both component mounting lines between the middle of one of the plurality of component mounting lines and the middle of the other component mounting line. By installing a bypass transport device, constructing a bypass mounting line that leads from the middle of the one component mounting line to the middle of the other component mounting line via the bypass transport device, the production management computer A normal production pattern for producing component mounting boards for each line and a bypass production pattern for producing component mounting boards on the bypass mounting line. It is obtained so as to select the production patterns of Luo each component mounting line.

この構成では、一方の部品実装ラインの途中からバイパス搬送装置を介して他方の部品実装ラインの途中につながるパイパス実装ラインを構築するため、各部品実装ライン間で重複する一部の装置（例えば印刷機、リフロー炉）を重複させないように各装置を配列したパイパス実装ラインを構築することができ、特許文献１のように２本以上の部品実装ラインの出口と入口をつなぎ合わせるライン構成と比較して、回路基板の搬送経路を短くすることができて、その分、サイクルタイムを短縮でき、生産性を向上できる。   In this configuration, since a bypass mounting line is connected from the middle of one component mounting line to the middle of the other component mounting line via the bypass conveyance device, some devices that overlap between the component mounting lines (for example, printing) Can be constructed to arrange each device so as not to overlap each other, and compared with a line configuration in which the outlets and inlets of two or more component mounting lines are connected as in Patent Document 1. As a result, the circuit board transfer path can be shortened, and the cycle time can be shortened accordingly, thereby improving the productivity.

この場合、請求項２のように、生産管理コンピュータは、目標サイクルタイム、装着する部品点数及び部品種類数に応じて通常生産パターンとパイパス生産パターンの中から生産パターンを選択するようにしても良い。このようにすれば、目標サイクルタイム、装着する部品点数及び部品種類数に応じて最適な生産パターンを選択することができる。   In this case, as in claim 2, the production management computer may select a production pattern from the normal production pattern and the bypass production pattern according to the target cycle time, the number of parts to be mounted, and the number of types of parts. . In this way, an optimal production pattern can be selected according to the target cycle time, the number of parts to be mounted, and the number of types of parts.

また、請求項３のように、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止している場合に、当該部品実装ラインのうちの故障又はエラー停止している装置よりも上流側の装置をバイパス搬送装置を介して他の部品実装ラインの途中に連結してパイパス実装ラインを構築し、生産管理コンピュータは、前記一部の装置が故障又はエラー停止している部品実装ラインについては、前記パイパス実装ラインを使用して部品実装基板を生産するようにしても良い。このようにすれば、いずれか部品実装ラインの一部の装置が故障又はエラー停止している場合でも、パイパス実装ラインを使用することで、故障又はエラー停止した装置を除外した搬送経路で部品実装基板を生産することができ、部品実装ラインの稼働率を向上できる。   Further, as in claim 3, when a part of one of the component mounting lines has a failure or an error stop, it is more than a failure or an error stop of the component mounting line. A bypass mounting device is connected to another component mounting line in the middle of another component mounting line to construct a bypass mounting line, and the production management computer uses a component mounting line in which some of the devices have failed or stopped due to an error. For the above, a component mounting board may be produced using the bypass mounting line. In this way, even if some devices on any of the component mounting lines are faulty or error stopped, by using the bypass mounting line, components can be mounted on the transport path excluding the devices that have failed or error stopped. Boards can be produced and the operating rate of the component mounting line can be improved.

また、請求項４のように、生産管理コンピュータは、複数本の部品実装ラインのうち、生産中の部品実装ラインのうちの一部の装置が故障又はエラー停止したときに、当該一部の装置が故障又はエラー停止した部品実装ラインについては、パイパス生産パターンに切り換えて当該部品実装ラインの途中から前記バイパス搬送装置を介して他の部品実装ラインの途中に連結して構築したパイパス実装ラインを使用して生産を継続するようにしても良い。このようにすれば、生産中に、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止した場合でも、パイパス実装ラインを使用して生産を継続することができ、部品実装ラインの稼働率を向上できる。   According to a fourth aspect of the present invention, when a part of the component mounting line in production out of a plurality of component mounting lines fails or an error stops, the production management computer For component mounting lines that fail or stop in error, use a bypass mounting line that is constructed by connecting to the other part mounting line via the bypass transfer device from the middle of the component mounting line by switching to the bypass production pattern. Then, production may be continued. In this way, even if a part of one of the component mounting lines fails or stops during an error during production, the production can be continued using the bypass mounting line. Can improve the operating rate.

この場合、パイパス実装ラインは、２本の部品実装ラインの途中をつなげて構築する場合（バイパス搬送装置が１箇所）に限定されず、請求項５のように、３本以上の部品実装ラインの途中をつなげるように構築しても良い（バイパス搬送装置が２箇所以上としても良い）。   In this case, the bypass mounting line is not limited to a case in which two component mounting lines are connected in the middle (one bypass conveyance device). You may build so that the middle may be connected (a bypass conveyance apparatus is good also as two or more places).

尚、請求項６に係る発明は、請求項１に係る「部品実装ラインの生産管理装置」の発明と実質的に同一の技術思想を「部品実装ラインの生産管理方法」の発明として記載したものである。   The invention according to claim 6 describes the technical idea substantially the same as the invention of the “production management apparatus for component mounting line” according to claim 1 as the invention of “production management method for component mounting line”. It is.

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に基づいて本実施例１の生産設備の構成例を説明する。
本実施例１では、２本の部品実装ラインＡ，Ｂが並設され、各部品実装ラインＡ，Ｂは、それぞれ印刷機Ａｐ，Ｂｐ、複数台の実装機Ａ１，Ａ２，Ｂ１，Ｂ２，Ｂ３、リフロー炉Ａｒ，Ｂｒ等が、回路基板を搬送するコンベアＡｃ１，Ａｃ２，Ｂｃ１，Ｂｃ２に沿って配列されている。その他、各部品実装ラインＡ，Ｂには、接着剤やフラックスの塗布装置、検査装置等を配置しても良い。 A first embodiment of the present invention will be described with reference to FIGS.
First, a configuration example of the production facility according to the first embodiment will be described with reference to FIG.
In the first embodiment, two component mounting lines A and B are juxtaposed, and each component mounting line A and B includes a printing machine Ap and Bp, and a plurality of mounting machines A1, A2, B1, B2, and B3, respectively. The reflow furnaces Ar, Br, etc. are arranged along the conveyors Ac1, Ac2, Bc1, Bc2 that convey the circuit board. In addition, each component mounting line A, B may be provided with an adhesive or flux coating device, an inspection device, or the like.

一方の部品実装ラインＡの途中と他方の部品実装ラインＢの途中との間に、両部品実装ラインＡ，Ｂ間で回路基板を搬送するバイパスコンベア１１（バイパス搬送装置）を設置して、一方の部品実装ラインＡの途中からバイパスコンベア１１を介して他方の部品実装ラインＢの途中につながるパイパス実装ラインを構築している。本実施例１では、作業者がバイパスコンベア１１の連結位置を任意に変更できるようになっており、図１に示す構成例では、一方の部品実装ラインＡのうちの下流側の実装機Ａ２の出口側のコンベアＡｃ２と、他方の部品実装ラインＢのうちの印刷機Ｂｐの出口側のコンベアＢｃ１との間をバイパスコンベア１１で連結している。これにより、両部品実装ラインＡ，Ｂ間で重複する一部の装置（例えば印刷機Ａｐ，Ｂｐ、リフロー炉Ａｒ，Ｂｒ）を重複させないように各装置を配列したパイパス実装ラインを構築している。   Between the middle of one component mounting line A and the middle of the other component mounting line B, a bypass conveyor 11 (bypass transport device) that transports the circuit board between the two component mounting lines A and B is installed. The bypass mounting line A is connected to the middle of the other component mounting line B from the middle of the component mounting line A. In the first embodiment, the operator can arbitrarily change the connection position of the bypass conveyor 11. In the configuration example shown in FIG. 1, the downstream mounting machine A <b> 2 of the one component mounting line A is used. A bypass conveyor 11 connects the outlet-side conveyor Ac2 and the outlet-side conveyor Bc1 of the printing machine Bp in the other component mounting line B. As a result, a bypass mounting line is constructed in which the respective devices are arranged so as not to overlap some of the devices (for example, the printing presses Ap and Bp and the reflow furnaces Ar and Br) that overlap between the component mounting lines A and B. .

２本の部品実装ラインＡ，Ｂの生産を管理する生産管理コンピュータ（図示せず）は、図２の生産管理プログラムを実行することで、各部品実装ラインＡ，Ｂ毎にそれぞれ部品実装基板を生産する通常生産パターン１，２と、バイパスコンベア１１を用いるパイパス実装ラインで部品実装基板を生産するパイパス生産パターン３の中から各部品実装ラインＡ，Ｂの生産パターンを選択するようにしている。   A production management computer (not shown) that manages the production of the two component mounting lines A and B executes the production management program shown in FIG. The production patterns for the component mounting lines A and B are selected from the normal production patterns 1 and 2 to be produced and the bypass production pattern 3 for producing the component mounting board on the bypass mounting line using the bypass conveyor 11.

生産管理コンピュータの記憶装置には、生産パターンの選択に必要な情報である、部品実装ライン構成情報、装置構成情報、部品装着情報等が記憶されている。ここで、部品実装ライン構成情報には、各部品実装ラインＡ，Ｂのライン名や並び順等の情報の他に、パイパス実装ラインの情報も含まれる。装置構成情報には、各実装機のレーン数、フィーダ配置、吸着ノズル、装着ヘッド等の情報が含まれる。部品装着情報には、部品の装着順、部品搭載スロット（フィーダの位置）、使用する吸着ノズルと装着ヘッド等の情報が含まれる。   The storage device of the production management computer stores component mounting line configuration information, device configuration information, component mounting information, and the like, which are information necessary for selecting a production pattern. Here, the component mounting line configuration information includes information on bypass mounting lines in addition to information such as line names and arrangement order of the component mounting lines A and B. The apparatus configuration information includes information such as the number of lanes of each mounting machine, feeder arrangement, suction nozzle, and mounting head. The component mounting information includes information such as a component mounting order, a component mounting slot (feeder position), a suction nozzle to be used, and a mounting head.

次に、図２の生産管理プログラムの処理内容を説明する。
図２の生産管理プログラムは、生産管理コンピュータによって、生産開始前に実行され、次のようにして生産パターンを選択する。まず、ステップ１０１で、目標サイクルタイムを設定し、次のステップ１０２で、装着する部品点数と部品種類数を設定する。 Next, processing contents of the production management program of FIG. 2 will be described.
The production management program in FIG. 2 is executed by the production management computer before the start of production, and selects a production pattern as follows. First, in step 101, the target cycle time is set, and in the next step 102, the number of parts to be mounted and the number of types of parts are set.

この後、ステップ１０３に進み、最適化の対象となるラインを選択する。図１のライン構成例では、２本の部品実装ラインＡ，Ｂとパイパス実装ラインの中から最適化の対象となるラインを選択する。この際、複数のラインを選択しても良い。   Thereafter, the process proceeds to step 103, and a line to be optimized is selected. In the line configuration example of FIG. 1, a line to be optimized is selected from the two component mounting lines A and B and the bypass mounting line. At this time, a plurality of lines may be selected.

この後、ステップ１０４に進み、選択したラインのサイクルタイムが目標サイクルタイム以内となるようにラインの各装着機のフィーダ配置等を最適化する。この後、ステップ１０５に進み、各ラインの最適化結果を表示装置（図示せず）に表示する。この後、ステップ１０６に進み、実際に生産に使用するライン（生産パターン）を選択する。この際、作業者が表示装置に表示された各ラインの最適化結果を見て、作業者が実際に生産に使用するライン（生産パターン）を任意に選択するようにしても良いし、各ラインの最適化結果からサイクルタイムが最短となるライン（生産パターン）を自動的に選択するようにしても良い。   Thereafter, the process proceeds to step 104, where the feeder arrangement and the like of each mounting machine on the line are optimized so that the cycle time of the selected line is within the target cycle time. Thereafter, the process proceeds to step 105, and the optimization result of each line is displayed on a display device (not shown). Thereafter, the process proceeds to step 106, and a line (production pattern) actually used for production is selected. At this time, the operator may arbitrarily select a line (production pattern) actually used for production by looking at the optimization result of each line displayed on the display device. A line (production pattern) having the shortest cycle time may be automatically selected from the optimization result.

以上説明した本実施例１によれば、一方の部品実装ラインＡの途中からバイパスコンベア１１を介して他方の部品実装ラインＢの途中につながるパイパス実装ラインを構築するため、各部品実装ラインＡ，Ｂ間で重複する一部の装置（例えば印刷機Ａｐ，Ｂｐ、リフロー炉Ａｒ，Ｂｒ）を重複させないように各装置を配列したパイパス実装ラインを構築することができ、パイパス実装ラインの回路基板の搬送経路を短くすることができて、その分、サイクルタイムを短縮でき、生産性を向上できる。   According to the first embodiment described above, in order to construct a bypass mounting line that leads from the middle of one component mounting line A to the middle of the other component mounting line B via the bypass conveyor 11, each component mounting line A, It is possible to construct a bypass mounting line in which each device is arranged so as not to overlap a part of devices that overlap between B (for example, the printing presses Ap and Bp and the reflow furnaces Ar and Br). The conveyance path can be shortened, and accordingly, the cycle time can be shortened and the productivity can be improved.

しかも、本実施例１では、目標サイクルタイム、装着する部品点数及び部品種類数に応じて通常生産パターンとパイパス生産パターンの中から生産パターンを選択するようにしたので、目標サイクルタイム、装着する部品点数及び部品種類数に応じて最適な生産パターンを選択することができる。   Moreover, in the first embodiment, since the production pattern is selected from the normal production pattern and the bypass production pattern according to the target cycle time, the number of parts to be mounted and the number of types of parts, the target cycle time, the parts to be mounted An optimal production pattern can be selected according to the number of points and the number of types of parts.

ところで、いずれかの部品実装ラインのうちの一部の装置（図３の例では部品実装ラインＡの実装機Ａ２）が故障又はエラー停止している場合は、当該部品実装ラインを使用する通常生産パターンでは生産できない。   By the way, when a part of one of the component mounting lines (the mounting machine A2 of the component mounting line A in the example of FIG. 3) has failed or stopped due to an error, normal production using the component mounting line is performed. It cannot be produced with patterns.

そこで、本発明の実施例２では、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止している場合に、当該部品実装ラインのうちの故障又はエラー停止している装置よりも上流側の装置をバイパスコンベア１１（バイパス搬送装置）を介して他の部品実装ラインの途中に連結してパイパス実装ラインを構築し、生産管理コンピュータは、前記一部の装置が故障又はエラー停止している部品実装ラインについては、前記パイパス実装ラインを使用して部品実装基板を生産するようにしている。   Therefore, in the second embodiment of the present invention, when a part of one of the component mounting lines is faulty or error-stopped, the faulty or error-stopped device of the component mounting line is used. In addition, the upstream device is connected to another component mounting line via the bypass conveyor 11 (bypass transport device) to construct a bypass mounting line. For the component mounting line, the component mounting board is produced using the bypass mounting line.

例えば、図３に示すライン構成例では、一方の部品実装ラインＡのうちの下流側の実装機Ａ２が故障又はエラー停止した状態となっている。この場合は、生産設備の稼働前に、一方の部品実装ラインＡのうちの上流側の実装機Ａ１をバイパスコンベア１１を介して他方の部品実装ラインＢの途中（１台目の実装機Ｂ１の上流側）につなげてパイパス実装ラインを構築し、実装機Ａ２が故障又はエラー停止している部品実装ラインＡについては、前記パイパス実装ラインを使用して部品実装基板を生産する。   For example, in the line configuration example shown in FIG. 3, the mounting machine A2 on the downstream side of one component mounting line A is in a state where it has failed or stopped due to an error. In this case, before the operation of the production facility, the upstream mounting machine A1 of the one component mounting line A is moved along the other component mounting line B via the bypass conveyor 11 (of the first mounting machine B1). A bypass mounting line is constructed by connecting to the upstream side, and for the component mounting line A in which the mounting machine A2 has failed or stopped in error, a component mounting board is produced using the bypass mounting line.

尚、３本以上の部品実装ラインを並設した生産設備では、一部の装置が故障又はエラー停止している部品実装ラインを、バイパスコンベア１１を介して他の部品実装ラインに連結する際に、連結可能な部品実装ラインが２本以上存在する場合がある。この場合は、連結可能な各部品実装ライン毎にそれぞれパイパス実装ラインを想定し、各パイパス実装ラインを最適化して、その結果からサイクルタイムが最短となるパイパス実装ライン（バイパス生産パターン）を選択するようにしても良い。   In a production facility in which three or more component mounting lines are arranged side by side, when connecting a component mounting line in which some of the devices have failed or error stopped to another component mounting line via the bypass conveyor 11 There may be two or more component mounting lines that can be connected. In this case, a bypass mounting line is assumed for each connectable component mounting line, each bypass mounting line is optimized, and a bypass mounting line (bypass production pattern) having the shortest cycle time is selected from the result. You may do it.

以上説明した本実施例２では、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止している場合に、当該部品実装ラインのうちの故障又はエラー停止している装置よりも上流側の装置をバイパスコンベア１１を介して他の部品実装ラインの途中に連結してパイパス実装ラインを構築するようにしたので、いずれか部品実装ラインの一部の装置が故障又はエラー停止している場合でも、パイパス実装ラインを使用することで、故障又はエラー停止した装置を除外した搬送経路で部品実装基板を生産することができ、部品実装ラインの稼働率を向上できる。   In the second embodiment described above, when some of the devices in any of the component mounting lines are out of order or out of order, the devices in the component mounting line are out of trouble or out of error. Since the upstream device is connected to the other component mounting line via the bypass conveyor 11 to construct the bypass mounting line, a part of the device mounting line may fail or stop due to an error. Even in such a case, by using the bypass mounting line, it is possible to produce a component mounting board on a transport path excluding a device in which a failure or error has stopped, and to improve the operating rate of the component mounting line.

本発明の実施例３では、複数本の部品実装ラインのうち、通常生産中の部品実装ラインのうちの一部の装置が故障又はエラー停止したときに、生産完了が生産計画の予定時間内に間に合わないような場合に、当該一部の装置が故障又はエラー停止した部品実装ラインについては、パイパス生産パターンに切り換えて当該部品実装ラインの途中から前記バイパス搬送装置を介して他の部品実装ラインの途中に連結して構築したパイパス実装ラインを使用して生産を継続するようにしている。   In the third embodiment of the present invention, when a part of a plurality of component mounting lines out of the component mounting lines under normal production has failed or stopped due to an error, the completion of production is within the scheduled time of the production plan. In the case where it is not in time, the component mounting line in which the part of the device fails or has stopped due to an error is switched to a bypass production pattern and the other component mounting line is passed through the bypass transport device from the middle of the component mounting line. Production is continued using a bypass mounting line constructed in the middle.

本実施例３の生産管理は、生産管理コンピュータによって図４の生産管理プログラムに従って次のように実行される。ステップ２０１で、通常生産パターンで生産を開始すると、ステップ２０２に進み、生産状況を監視して、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止したか否かを監視する。   The production management of the third embodiment is executed as follows according to the production management program of FIG. 4 by the production management computer. When production is started in the normal production pattern in step 201, the process proceeds to step 202, where the production status is monitored to monitor whether or not some of the devices in any of the component mounting lines have failed or stopped due to an error. .

その後、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止したことが検出されると、ステップ２０３に進み、生産計画の予定時間内に生産完了可能か否かを判定し、予定時間内に生産完了可能と判定されれば、ステップ２０４に進み、そのまま生産を継続して上記ステップ２０２の監視処理に戻る。   Thereafter, when it is detected that some of the devices in any of the component mounting lines has failed or stopped due to an error, the process proceeds to step 203 to determine whether production can be completed within the scheduled time of the production plan. If it is determined that the production can be completed within the scheduled time, the process proceeds to step 204, the production is continued as it is, and the process returns to the monitoring process in step 202.

これに対し、上記ステップ２０３で、予定時間内に生産完了可能でないと判定されれば、ステップ２０５に進み、一部の装置が故障又はエラー停止した部品実装ラインに連結可能なパイパス実装ライン（最適化の対象ライン）を選択する。この際、一部の装置が故障又はエラー停止した部品実装ラインに連結可能なパイパス実装ラインが複数本存在する場合は、複数のラインを選択しても良い。   On the other hand, if it is determined in step 203 that production cannot be completed within the scheduled time, the process proceeds to step 205, where a bypass mounting line (optimum) that can be connected to a component mounting line in which some of the devices have failed or stopped due to an error. Select the target line). At this time, if there are a plurality of bypass mounting lines that can be connected to a component mounting line in which some of the devices have failed or stopped due to an error, a plurality of lines may be selected.

この後、ステップ２０６に進み、選択したラインのサイクルタイムが目標サイクルタイム以内となるようにラインの各装着機のフィーダ配置等を最適化する。この後、ステップ２０７に進み、生産計画の予定時間内に生産完了可能か否かを判定し、予定時間内に生産完了可能でないと判定されれば、上記ステップ２０５に戻る。これにより、予定時間内に生産完了可能と判定されるまで、上述した最適化の対象ラインの選択と最適化の処理を繰り返す。その後、予定時間内に生産完了可能と判定された時点で、ステップ２０８に進み、最適化したジョブ（Ｊｏｂ）を記憶装置に保存して、本プログラムを終了する。   Thereafter, the process proceeds to step 206, and the feeder arrangement and the like of each mounting machine on the line are optimized so that the cycle time of the selected line is within the target cycle time. Thereafter, the process proceeds to step 207, where it is determined whether the production can be completed within the scheduled time of the production plan. If it is determined that the production cannot be completed within the scheduled time, the process returns to step 205. Thus, the selection of the optimization target line and the optimization process described above are repeated until it is determined that the production can be completed within the scheduled time. Thereafter, when it is determined that the production can be completed within the scheduled time, the process proceeds to step 208, the optimized job (Job) is stored in the storage device, and this program is terminated.

以上説明した本実施例３では、生産中に、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止した場合に、生産計画の予定時間内に生産が完了しないと判断したときに、当該一部の装置が故障又はエラー停止した部品実装ラインについては、パイパス実装ラインを使用して生産を継続するようにしたので、生産中に、いずれかの部品実装ラインのうちの一部の装置が故障又はエラー停止した場合でも、生産を継続することができ、部品実装ラインの稼働率を向上できる。   In the third embodiment described above, when it is determined that the production is not completed within the scheduled time of the production plan when some devices in any of the component mounting lines fail or stop due to an error during the production. In addition, the component mounting line in which some of the devices fail or stopped due to an error has been produced using the bypass mounting line. Production can be continued even when the device is out of order or stopped due to an error, and the operating rate of the component mounting line can be improved.

前述した図１の生産設備の構成例では、２本の部品実装ラインＡ，Ｂを並設したが、図５に示す本発明の実施例４では、３本の部品実装ラインＡ，Ｂ，Ｃを並設している。部品実装ラインＡ，Ｂの構成は、図１の部品実装ラインＡ，Ｂと同じである。部品実装ラインＣは、印刷機Ｃｐ、複数台の実装機Ｃ１〜Ｃ５、リフロー炉Ｃｒ等を、コンベアＣｃ１，Ｃｃに沿って配列している。そして、部品実装ラインＣのうちの上流側から例えば２台目の実装機Ｃ２の出口側のコンベアＣｃ２と、部品実装ラインＡのうちの下流側の実装機Ａ２の出口側のコンベアＡｃ２との間をバイパスコンベア１２で連結している。これにより、図１の構成例に対して、部品実装ラインＣで部品実装基板を生産する通常生産パターン４と、バイパスコンベア１２を用いるパイパス実装ラインで部品実装基板を生産するパイパス生産パターン５を追加した構成となっている。その他の事項は、図１と同じであり、生産管理方法も、前記実施例１〜３と同様に行えば良い。   In the configuration example of the production facility shown in FIG. 1 described above, two component mounting lines A and B are provided side by side. However, in the fourth embodiment of the present invention shown in FIG. 5, three component mounting lines A, B, and C are provided. Are installed side by side. The configuration of the component mounting lines A and B is the same as that of the component mounting lines A and B in FIG. In the component mounting line C, a printing machine Cp, a plurality of mounting machines C1 to C5, a reflow furnace Cr, and the like are arranged along the conveyors Cc1 and Cc. Then, from the upstream side of the component mounting line C, for example, between the conveyor Cc2 on the outlet side of the second mounting machine C2 and the conveyor Ac2 on the outlet side of the downstream mounting machine A2 of the component mounting line A Are connected by a bypass conveyor 12. Accordingly, a normal production pattern 4 for producing a component mounting board on the component mounting line C and a bypass production pattern 5 for producing a component mounting board on the bypass mounting line using the bypass conveyor 12 are added to the configuration example of FIG. It has become the composition. Other matters are the same as those in FIG. 1, and the production management method may be performed in the same manner as in the first to third embodiments.

尚、各部品実装ラインＡ〜Ｃに対してバイパスコンベア１１，１２を連結する位置を適宜変更しても良い。
また、一方の部品実装ラインの途中と他方の部品実装ラインの途中との間のバイパス搬送装置は、バイパスコンベアに限定されず、自動搬送ロボットを用いても良い。 In addition, you may change suitably the position which connects the bypass conveyors 11 and 12 with respect to each component mounting line AC.
Moreover, the bypass conveyance apparatus between the middle of one component mounting line and the middle of the other component mounting line is not limited to the bypass conveyor, and an automatic conveyance robot may be used.

また、パイパス実装ラインは、２本の部品実装ラインの途中をつなげて構築する場合（バイパス搬送装置が１箇所）に限定されず、３本以上の部品実装ラインの途中をつなげるように構築しても良い（バイパス搬送装置が２箇所以上としても良い）。   In addition, the bypass mounting line is not limited to the case where two component mounting lines are connected in the middle (one bypass conveyance device is provided), and is constructed so as to connect three or more component mounting lines. It is also possible (two or more bypass conveyance devices may be provided).

その他、本発明は、４本以上の部品実装ラインを並設した構成としても良く、また、各部品実装ラインを構成する各装置の台数を変更したり、部品実装ライン中に接着剤やフラックスの塗布装置、検査装置等を配置したり、検査装置で検出された不良基板を不良基板修正ラインへ転送しても等、要旨を逸脱しない範囲内で種々変更して実施できることは言うまでもない。   In addition, the present invention may have a configuration in which four or more component mounting lines are juxtaposed, change the number of devices constituting each component mounting line, or change the number of adhesives and fluxes in the component mounting line. Needless to say, various changes can be made without departing from the gist of the invention, such as disposing a coating device, an inspection device, or transferring a defective substrate detected by the inspection device to a defective substrate correction line.
