  FIG. 1 is a plan view showing an outline of an embodiment of a board production system according to the present invention, FIG. 2 is a plan view showing an electronic component mounting machine shown in FIG. 1, and FIG. FIG. 4 is a flowchart showing a program executed by the first shift device shown in FIG. 1, and FIG. 4 is a flowchart showing a program executed by the host computer shown in FIG.

生産を開始する前に、生産スケジュールを予め設定する。すなわち、基板の基板幅、バックアップ装置の基板を支持する支持部の配置等が共通であり、段取り替えが少ない基板品種をグループ化し、各グループと各グループに属する基板品種が搬入される各コンベヤとの対応関係付けを行う。具体的には、品種Ｓ１、品種Ｓ４は基板幅が同じでありかつ同じバックアップ装置を使用するのでコンベヤ幅およびバックアップ装置の変更が不要であるため、品種Ｓ１と品種Ｓ４をグループ化する。また、品種Ｓ２、品種Ｓ３は基板幅は異なっておりコンベヤ幅の変更は必要であるもののバックアップ装置の変更が不要であるため、品種Ｓ２と品種Ｓ３をグループ化する。そして、品種Ｓ１と品種Ｓ４のグループと電子部品実装機１５，１６の第１ラインＬ１とを対応関係付けし、品種Ｓ２と品種Ｓ３のグループと電子部品実装機１５，１６の第２ラインＬ２とを対応関係付けして、下記表２に示すようなこれら対応関係を示すテーブルを作成し第１シフト装置１３の制御装置１３ｂに記憶させる。なお、生産数の多い基板品種については複数のコンベヤに搬入されるような対応関係付けすればよい。

第１シフト装置１３の制御装置１３ｂは、第１シフト装置１３に基板Ｓが搬入されると、第３図に示すプログラムを実行する。基板ＳのＩＤを読み取って基板品種を認識し（ステップ１０２）、認識した基板品種と、上記表２に示す基板品種とコンベヤとの対応関係を示すテーブルとに基づいて基板に割り当てられたコンベヤを選択し（ステップ１０４）、基板が基板品種の属するグループに割り当てられたコンベヤに搬入されるように第１振り分け装置１３を制御する（ステップ１０６）。
実際には、電子部品実装機１５，１６の第１ラインＬ１を品種Ｓ１の基板幅に合わせてコンベヤ幅を２００ｍｍに設定するとともに、タイプ１のバックアップ装置を設置した後、生産を開始する。基板生産システムは品種Ｓ１を第１ラインＬ１に払い出すように制御する。そして、電子部品を基板上に実装して後工程に搬出する。かかる生産中、電子部品実装機１５，１６の第２ラインＬ２を品種Ｓ２の基板幅に合わせてコンベヤ幅を１５０ｍｍに設定する。
品種Ｓ１の生産が終了すると、基板生産システムは品種Ｓ２を第２ラインＬ２に払い出すように制御して品種Ｓ２の生産を開始する。そして、品種Ｓ２の生産が終了すると、電子部品実装機１５，１６の第２ラインＬ２を品種Ｓ３の基板幅に合わせてコンベヤ幅を１００ｍｍに設定した後、生産を開始する。基板生産システムは品種Ｓ２に続けて品種Ｓ３を第２ラインＬ２に払い出すように制御する。そして、電子部品を基板上に実装して後工程に搬出する。
品種Ｓ３の生産が終了すると、基板生産システムは、コンベヤ幅が２００ｍｍでありかつタイプ１のバックアップ装置を設置したままの第１ラインＬに品種Ｓ４を払い出すように制御する。一方、第２ラインＬ２のコンベヤ幅を品種Ｓ４の基板幅に合わせて２００ｍｍに設定した後、第２ラインＬ２にも品種Ｓ４を払い出すように制御して、第１および第２ラインＬ１，Ｌ２の両ラインにて品種Ｓ４を生産するようにする。そして、電子部品を基板上に実装して後工程に搬出する。
上述した説明から理解できるように、この実施の形態においては、互いに異なる複数種類の品種Ｓ１，Ｓ２，Ｓ３，Ｓ４を連続して生産する場合、異なる複数種類の基板品種のうち、連続して生産したときに段取り替え作業が不要かまたは少なくて済む異なる基板品種が同じグループに所属するようにグループ化し、各グループと該各グループに属する基板品種が搬入される各コンベヤとの対応関係付けを行い、各基板が基板品種の属するグループに割り当てられたコンベヤに搬入されるように第１振り分け装置を制御するので、同じ基板幅の基板を連続して生産したり、同じバックアップ装置を使用して連続して生産したり、同じ部品供給装置を使用して連続して生産したりすることができる。したがって、実装ラインのコンベヤ幅の変更、バックアップ装置の基板を支持する支持部の配置の変更などの段取り替えの回数を極力少なくして異なる種類の基板を生産することができるので、基板生産システムの生産性を向上することができる。
また、上記した実施の形態においては、電子部品実装機２０を複数台直列に配置して実装ラインを構成したので、複数の基板を実装ライン上の所望の停止位置にそれぞれ別々に停止させて部品を実装することができる。
さらに、比較的生産枚数の少ない基板品種Ｓ１〜Ｓ３については、これらが連続して第１ラインＬ１又は第２ラインＬ２で生産されるように設定したので、第１および第２ラインＬ１，Ｌ２がともに品種Ｓ１〜Ｓ３を一種類ずつ生産していく場合のように段取り替えによって第１および第２ラインＬ１，Ｌ２の両方での生産が完全にストップすることはなく、各品種の基板の予定枚数の生産時間が比較的短い（段取り替えに要する時間と大差ない場合）のであれば、前者の場合よりも効率よく生産計画を遂行することが可能になる。また、品種Ｓ１〜Ｓ３の生産が全て終了した後に、比較的生産枚数の多い基板品種Ｓ４を第１および第２ラインＬ１，Ｌ２の両方において生産するようにしたため、品種Ｓ１〜Ｓ３の生産途中にＳ４を生産する場合と比べて、段取り替えにより生産をストップさせる時間を短くでき、効率のよい生産が行える。
また、以上の事由を考慮して、生産計画における品種Ｓ１〜Ｓ４の順番を自動的に決定したり最適化すべく変更することも可能である。この場合、例えば、当初はホストコンピュータ１９には生産すべき基板の品種とその枚数の情報だけが供給され品種の生産順番に関する情報が供給されない場合、又は、当初はホストコンピュータ１９に供給された（若しくはホストコンピュータ１９において作成された）生産計画が上記表１とは異なりＳ１→Ｓ２→Ｓ４→Ｓ３の順に生産するものである場合であったとしても、上記表２に示したように各基板品種とそれを搬送するコンベヤとの対応付けを行った結果、Ｓ１〜Ｓ３は一方のコンベヤによって搬送され、Ｓ４は両方のコンベヤによって搬送されることを考慮すれば、Ｓ１〜Ｓ３の生産が全て終了した後にＳ４を生産するようにした順番が望ましいと判断できるとの理由により、順番をＳ１→Ｓ２→Ｓ３→Ｓ４に変更することが生産効率上望ましいとの判断がなされれば、このように生産計画を設定または修正するのである。
このような生産順番を決定する判断に関する処理は、第４図に示すようにプログラムをホストコンピュータ１９によって行うようにすればよい。ホストコンピュータ１９は、対応関係付け工程（ステップ２０２）により品種の異なる基板のそれぞれに対して、複数のコンベヤのうち少なくとも一つを選択して対応関係付けを行うことにより基板品種と選択された搬送コンベヤとの対応関係を示す対応情報である上述した表２に示すテーブルを生成し、生産順番決定工程（ステップ２０４）により対応関係付け工程において生成された基板品種と選択された搬送コンベヤとの対応関係を示す対応情報に基づいて、基板の各種類の生産順番を決定し、基板搬入工程（ステップ２０６）により対応情報および生産順番決定工程において生産された生産順番情報である上述した表１に示すテーブルに基づいて基板が基板品種の属するグループに割り当てられたコンベヤに搬入されるように第１振り分け装置１３を制御する。したがって、段取り替えの回数を少なくするように生産計画を設定又は変更することができるので、時間的にも作業コスト的にも効率よく生産することができる。
なお、上述した実施の形態においては、いわゆるダブルトラックコンベヤ方式の電子部品実装機２０を直列に並べて複数の実装ラインを構成するようにしたが、シングルトラックコンベヤ方式の電子部品実装機を直列に並べて構成した実装ラインを２列以上に並設するようにしてもよい。
また、上述した実施の形態においては、実装ラインを複数の電子部品実装機２０を並べて構成したものに本発明を適用したが、実装ラインを１つの電子部品実装機によって構成したものに適用するようにしてもよい。
また、上述した実施の形態においては、第２振り分け装置である第２シフト装置１４は、実装ラインから搬入された基板をリフロー装置１７と収納装置１８からなる１つの搬出ラインに搬出するようにしたが、例えばリフロー装置１７と収納装置１８からなる複数の搬出ラインのいずれかに搬出するようにしてもよい。これによれば、この第２シフト装置によって所望の搬出ラインに実装された基板を搬出することができる。
また、上述した実施の形態においては、基板の基板幅、バックアップ装置の基板を支持する支持部の配置が共通であり、段取り替えが少ない基板品種をグループ化し、各グループと各グループに属する基板品種が搬入される各コンベヤとの対応関係付けを行うようにしたが、部品供給装置の部品構成が共通であり、段取り替えが少ない基板品種をグループ化し、各グループと各グループに属する基板品種が搬入される各コンベヤとの対応関係付けを行うようにしてもよい。
また、上述した実施の形態においては、第１シフト装置１３の制御装置１３ｂが上記テーブルを記憶し、第３図に示すフローチャートに対応したプログラムを実行するようにしたが、第１シフト装置１３の制御装置１３ｂの代わりにホストコンピュータ１９を使用するようにしてもよい。Hereinafter, an embodiment of a substrate production system according to the present invention will be described. FIG. 1 is a plan view showing an outline of the substrate production system A. FIG.

The printing device 12 prints cream solder on the component mounting portion of the board carried in from the supply device 11 and carries it out to the first shift device 13 which is a first sorting device. The first shift device 13 includes an ID recognition unit 13a that reads an ID (information such as a board type) provided on the board, and based on the read board ID and a preset production schedule. The board carried in from the printing apparatus 12 is distributed to the first or second lines L1 and L2 of the electronic component mounting machines 15 and 16 and delivered. The first and second shift devices 13 and 14 include control devices 13b and 14a, and the control devices 13b and 14a control the operation of the first and second shift devices 13 and 14, respectively.
The control device 13b of the first shift device 13 includes a group in which different substrate types among a plurality of different types of substrate types belong to the same group so that different substrate types that do not require or require less setup change work are produced. And a table (see Table 2 below) showing the correspondence between each group and each conveyor into which the board type belonging to each group is carried. The board type means the type of product produced as a result of mounting the parts on the board. The type, number, and position of the parts to be mounted even if the board has the same shape and size. If any one of them is different, they are regarded as substrates of different varieties. In addition, the changeover work performed when changing the type of board to be produced includes changing the width of the conveyer corresponding to the size of the board, changing the position of the backup pin of the backup device described later, etc. It is work. For example, for two varieties with the same board outline and different parts to be mounted, it is not necessary to change the conveyor width for the setup change between the two varieties. In many cases, the amount of work is small compared to the setup change work between two different varieties.
Further, the control device 13b executes a program corresponding to the flowchart of FIG. 3 to control the first shift device 13 so that each board is carried into a conveyor assigned to a group to which the board type belongs.

The mounting line is configured in series. On the base 21 of the electronic component mounting machine 20, a board transfer device 30 for transferring the board S in the Y direction is provided. The substrate transport device 30 transports the substrate S in a predetermined direction (right direction in FIG. 1), and includes first and second conveyors 31 and 32 assembled in parallel to each other on the base 21. . A series of the first and second conveyors 31 and 32 is the first and second lines L1 and L2.
The first and second conveyors 31 and 32 respectively include first guide rails 31a and 32a and second guide rails 31b and 32b that extend in the transport direction and are arranged to face each other in parallel. The first and second guide rails 31a, 31b and 32a, 32b guide the substrate S in the transport direction, respectively. In addition, the substrate transport apparatus 30 is provided with a pair of conveyor belts provided in parallel to each other immediately below the first and second guide rails 31a, 32a and 31b, 32b. These conveyor belts support the substrate S and transport it in the transport direction.
The first guide rails 31a, 32a and the second guide rails 31b, 32b move together with the respective conveyor belts directly below the guide rails 31a, 32a, 31b, 32b in a direction (X direction) perpendicular to the conveying direction to fix the positioning. It has come to be. Thereby, each conveyor 31 and 32 can change a conveyor width corresponding to the board | substrate width of the board | substrate S to convey.
The substrate transport device 30 is provided with a backup device that pushes up and clamps (positions and supports) the substrate S transported to a predetermined mounting position. FIG. 2 shows a state where the backup device 33 is installed on the first conveyor L1 and the backup device is not installed on the second conveyor L2. The backup device has a plurality of backup pins that are erected on the upper surface and support the substrate S by pushing it up from below, and these backup pins are arranged at positions that effectively support the substrate. This arrangement differs depending on the substrate type. Some backup devices support the substrate S by means other than backup pins.
A moving table 41 elongated in the Y direction is located above the substrate transfer device 30 (upward in the direction perpendicular to the paper surface in FIG. 1). A fixed rail (frame) 42 extending in the X direction perpendicular to the Y direction extends in the X and Y directions. It is supported movably. The movement of the moving table 41 in the X and Y directions is controlled by a servo motor through a ball screw. A component transfer device 43 is attached to the moving table 41. The component transfer device 43 includes a support base 45 that is detachably attached to the moving table 41, and is supported by the support base 45 so as to be movable up and down in a Z direction perpendicular to the X direction and the Y direction. The component mounting head 46 is controlled to move up and down, and is provided with a cylindrical suction nozzle 47 that protrudes downward from the component mounting head 46 and holds the electronic component P at the lower end.
Electronic component supply devices 50 are arranged on both sides of the electronic component mounting machine 20 with a substrate transfer device 30 interposed therebetween. The electronic component supply device 50 includes a number of detachable cassette type feeders (component supply cassettes) 51. They are arranged side by side. The cassette type feeder 51 includes a main body 51a, a supply reel 51b provided at the rear of the main body 51a, and a component take-out part 51c provided at the tip of the main body 51a. An elongated tape (not shown) in which electronic components are enclosed at a predetermined pitch is wound and held on the supply reel 51b. This tape is pulled out at a predetermined pitch by a sprocket (not shown), and the electronic component is released from the enclosed state. The components are sequentially sent to the component take-out portion 51c. The electronic component supply device 50 is not only a cassette type but also a tray type in which electronic components are arranged on a tray.
The first and second electronic component mounting machines 15 and 16 include control devices 15a and 16a, and the control devices 15a and 16a carry in, carry out, and position the substrates of the first and second electronic component mounting machines 15 and 16, respectively. Supports operation and mounting of parts.
The second shift device 14 which is a second sorting device carries out the substrate carried in from the first or second line L1, L2 of the electronic component mounting machine 15, 16 to the reflow device 17, and the reflow device 17 is The electronic component P is soldered to the board S on which the electronic component P is mounted, and the storage device 18 stores the base S on which the electronic component P is soldered in a vertical direction.
The first and second shift devices 13 and 14 and the first and second electronic component mounters 15 and 16 described above are connected to a host computer 19. The host computer 19 provides information necessary for production such as a production schedule to the first and second shift devices 13 and 14 and the first and second electronic component mounting machines 15 and 16, and the first and second shift devices 13. , 14, and the first and second electronic component mounting machines 15, 16 receive information accompanying production.
Next, a case where the varieties S1, S2, S3, and S4 shown in Table 1 below are continuously produced by the substrate production system configured as described above will be described.

Before starting production, a production schedule is set in advance. In other words, the substrate width of the substrate, the arrangement of the support unit for supporting the substrate of the backup device, etc. are common, grouping the substrate types with few setup changes, and each conveyor and each conveyor into which the substrate types belonging to each group are carried Correspondence of Specifically, since the types S1 and S4 have the same substrate width and use the same backup device, it is not necessary to change the conveyor width and the backup device, so the types S1 and S4 are grouped. The types S2 and S3 have different substrate widths and need to change the conveyor width, but do not need to change the backup device, so the types S2 and S3 are grouped. Then, the group of the types S1 and S4 and the first line L1 of the electronic component mounting machines 15 and 16 are associated with each other, and the group of the types S2 and S3 and the second line L2 of the electronic component mounting machines 15 and 16 are And a table showing these correspondences as shown in Table 2 below is created and stored in the control device 13b of the first shift device 13. In addition, what is necessary is just to make it correspond so that board types with much production number may be carried in to several conveyors.

When the substrate S is loaded into the first shift device 13, the control device 13b of the first shift device 13 executes the program shown in FIG. The substrate type is recognized by reading the ID of the substrate S (step 102), and the conveyor assigned to the substrate based on the recognized substrate type and the table showing the correspondence between the substrate type and the conveyor shown in Table 2 above. The first sorter 13 is controlled (step 106) so that the board is carried into the conveyor assigned to the group to which the board type belongs (step 106).
Actually, the first line L1 of the electronic component mounting machines 15 and 16 is set to 200 mm in accordance with the board width of the product S1, and the production is started after the type 1 backup device is installed. The substrate production system controls the product S1 to be paid out to the first line L1. And an electronic component is mounted on a board | substrate and it carries out to a post process. During the production, the conveyor line is set to 150 mm by matching the second line L2 of the electronic component mounting machines 15 and 16 with the board width of the product type S2.
When the production of the product type S1 is completed, the substrate production system controls the product type S2 to be delivered to the second line L2, and starts production of the product type S2. When the production of the product type S2 is completed, the second line L2 of the electronic component mounting machines 15 and 16 is set to the substrate width of the product type S3 to set the conveyor width to 100 mm, and then the production is started. The board production system controls the product S3 to be delivered to the second line L2 following the product S2. And an electronic component is mounted on a board | substrate and it carries out to a post process.
When the production of the product type S3 is completed, the substrate production system controls to deliver the product type S4 to the first line L with the conveyor width of 200 mm and the type 1 backup device installed. On the other hand, after the conveyor width of the second line L2 is set to 200 mm in accordance with the substrate width of the product type S4, control is performed so that the product type S4 is also delivered to the second line L2, and the first and second lines L1, L2 are controlled. Production line S4 is produced in both lines. And an electronic component is mounted on a board | substrate and it carries out to a post process.
As can be understood from the above description, in this embodiment, when a plurality of different types of varieties S1, S2, S3, and S4 are continuously produced, among the plurality of different types of substrate varieties, the production is continued. Grouping so that different board types that do not require or require less setup changes belong to the same group, and associate each group with each conveyor that carries board types belonging to each group. Since the first sorter is controlled so that each board is carried into the conveyor assigned to the group to which the board type belongs, the boards with the same board width can be produced continuously or continuously using the same backup equipment. Or can be produced continuously using the same component supply device. Therefore, it is possible to produce different types of boards by minimizing the number of setup changes such as changing the conveyor width of the mounting line and changing the arrangement of the support parts that support the board of the backup device. Productivity can be improved.
Further, in the above-described embodiment, since the mounting line is configured by arranging a plurality of electronic component mounting machines 20 in series, the plurality of boards are separately stopped at desired stop positions on the mounting line, respectively. Can be implemented.
Furthermore, since the board types S1 to S3 with a relatively small number of boards are set to be continuously produced on the first line L1 or the second line L2, the first and second lines L1 and L2 are In both cases, production in both the first and second lines L1 and L2 is not completely stopped by the setup change as in the case of producing the varieties S1 to S3 one by one. If the production time is relatively short (when it is not much different from the time required for the setup change), the production plan can be executed more efficiently than the former case. In addition, after all the production of the varieties S1 to S3 is completed, the substrate varieties S4 having a relatively large number of productions are produced in both the first and second lines L1 and L2, so that the varieties S1 to S3 are being produced. Compared with the case of producing S4, the time for stopping production can be shortened by the setup change, and efficient production can be performed.
In consideration of the above reasons, the order of the varieties S1 to S4 in the production plan can be automatically determined or changed to be optimized. In this case, for example, the host computer 19 is initially supplied with only information on the type and number of boards to be produced and is not supplied with information on the production order of the types, or initially supplied to the host computer 19 ( Even if the production plan (created in the host computer 19) is different from the above table 1 and is produced in the order of S1->S2->S4-> S3, as shown in the above-mentioned table 2, each board type As a result of associating it with the conveyor that conveys it, S1 to S3 are conveyed by one conveyor, and S4 is conveyed by both conveyors. The order may be changed from S1 to S2 to S3 to S4 because it can be determined that the order in which S4 is produced later is desirable. If makes a determination of the production efficiency desired is to set or modify the production plan in this way.
Such processing relating to the determination of determining the production order may be performed by the host computer 19 as shown in FIG.
