Abstract

In this invention, for the first two boards in the order of transport among four boards, component mounting is executed in the following manner: the first board B1 is transported, in an initial mounting mode, to the second mounting position Pm2 from the upstream side in a board transport direction X, and the second board B2 is transported, in a regular mounting mode, to the first mounting position Pm1 from the upstream side in the board transport direction X. This allows the boards B2 and B1 to be transported respectively to the two mounting positions Pm1 and Pm2, and the component mounting onto the boards B2 and B1 to be started at each of the mounting positions Pm1 and Pm2. As a result, a drop in the operational capacity of a component mounting system 1 can be suppressed.

Description

部品実装システム、部品実装方法Component mounting system, component mounting method
 この発明は、基板搬送方向に基板を搬送しつつ、基板搬送方向に並ぶ複数の実装ステージで基板に部品を実装する技術に関する。 The present invention relates to a technology for mounting components on a substrate at a plurality of mounting stages aligned in the substrate transfer direction while transferring the substrate in the substrate transfer direction.
 従来、基板の搬送方向に並ぶ複数の実装部を備えた部品実装システムが知られている。また、特許文献1に示されるように、このような部品実装システムでは、1枚の基板に対する部品の実装を複数の実装部で分担することができる。つまり、基板は搬送方向に搬送されつつ複数の実装部に順番に停止し、各実装部は停止中の基板に対して担当する部品の実装を行う。これによって、部品実装の効率化を図ることができる。 BACKGROUND Conventionally, there is known a component mounting system provided with a plurality of mounting portions aligned in the transport direction of a substrate. In addition, as disclosed in Patent Document 1, in such a component mounting system, mounting of components on one board can be shared by a plurality of mounting units. That is, the substrate is sequentially stopped at the plurality of mounting portions while being transported in the transport direction, and each mounting portion mounts the part in charge on the substrate being stopped. This can improve the efficiency of component mounting.

 しかしながら、状況によっては、かかる手法が必ずしも効率的でない場合がある。つまり、部品実装システムに最初に搬入される基板は、搬送方向の最上流の実装ステージ(実装部)に停止して、この実装ステージにおいて部品の実装を受ける。この間、最上流の実装部よりも搬送方向の下流側の実装ステージは稼動しないため、部品実装システムの稼働率は、下流側の実装ステージが稼動する場合と比較して低くなる。そして、このような稼働率の低下は、部品実装システムで搬送する基板が少ない場合に特に顕著となる。 However, depending on the circumstances, such an approach may not always be efficient. That is, the substrate first carried into the component mounting system is stopped at the most upstream mounting stage (mounting portion) in the transport direction, and the mounting of components is received at this mounting stage. During this time, since the mounting stage on the downstream side in the transport direction does not operate than the most upstream mounting unit, the operation rate of the component mounting system is lower than that in the case where the mounting stage on the downstream operates. And such a fall of the operation rate becomes remarkable especially when there are few substrates conveyed by a component mounting system.
 この発明は上記課題に鑑みなされたものであり、複数の実装ステージが基板搬送方向に並ぶ部品実装システムにおいて、部品実装システムの稼働率の低下を抑制可能とする技術の提供を目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a technology capable of suppressing a decrease in operation rate of a component mounting system in a component mounting system in which a plurality of mounting stages are arranged in the substrate transfer direction.

It is provided corresponding to a conveyance unit to be conveyed, M mounting stages corresponding to M mounting stages, and M mounting units capable of mounting the same kind of component on a substrate stopped at each corresponding mounting stage, and provided on one substrate A mounting stage in which component mounting for a plurality of mounting target points is distributed among M mounting stages, and the one substrate is transported by the transport unit in the substrate transport direction while the component mounting is distributed among the M mounting stages And a control unit for performing component mounting distributed to the corresponding mounting stage to the one substrate stopped at the mounting stage corresponding to the mounting unit, the mounting stage including the distributed component mounting But The transferred substrate is transported to the downstream side of the substrate transport direction, and the control unit initially sets the transport order N (N is an integer of 1 or more) of the L substrates to the substrate transport direction to the substrate less than M. Component mounting is performed in the mounting mode, and component mounting is performed in the normal mounting mode for substrates having a transport order N of M or more, and in the initial mounting mode, of the M mounting stages for the substrate with the transport order N Component mounting on the substrate is selectively distributed to the mounting stage downstream of the (M−N) th mounting stage counted from the upstream side of the substrate transport direction, and the substrate is up to the (M−N) th mounting stage Components are mounted to a plurality of mounting target points on the board in the mounting stage downstream of the (M−N) th mounting stage, and in the normal mounting mode, each of the M mounting stages Component mounting on the board is distributed Will stop in order to M implementation stages, each component mounting to a plurality of mounting object point of the substrate sequentially in the M mounting stage is executed.
 本発明に係る部品実装方法は、基板搬送方向に並ぶM個(Mは2以上の整数)の実装ステージを有する搬送部によって、L枚(LはMより大きい整数)の基板を順番に基板搬送方向に搬送する工程と、一の基板に設けられた複数の実装対象点に対する部品実装をM個の実装ステージの間で分配し、当該一の基板を搬送部によって基板搬送方向に搬送しつつM個の実装ステージのうち部品実装を分配した実装ステージに停止させて、実装ステージで停止する当該一の基板に対して実装ステージに分配された部品実装を実行する工程とを備え、L枚の基板のうち基板搬送方向への搬送順序N(Nは1以上の整数)がM未満の基板に対しては初期実装モードで部品実装を実行し、搬送順序NがM以上の基板に対しては通常実装モードで部品実装を実行し、初期実装モードでは、搬送順序Nの基板に関して、M個の実装ステージのうち基板搬送方向の上流側から数えて(M-N)番目の実装ステージよりも下流側の実装ステージに基板への部品実装が選択的に分配され、基板は(M-N)番目までの実装ステージを通過して、(M-N)番目の実装ステージよりも下流側の実装ステージで基板の複数の実装対象点への部品実装が実行され、通常実装モードでは、M個の実装ステージのそれぞれに基板への部品実装が分配され、基板はM個の実装ステージに順番に停止して、M個の実装ステージのそれぞれで順番に基板の複数の実装対象点への部品実装が実行される。 In the component mounting method according to the present invention, L transport substrates (L is an integer larger than M) are transported in order by the transport unit having M (M is an integer of 2 or more) mounting stages arranged in the substrate transport direction. The step of transporting in the direction and component mounting for a plurality of mounting target points provided on one substrate are distributed among the M mounting stages, and the one substrate is transported by the transport unit in the substrate transport direction while the M Stopping at the mounting stage to which the component mounting is distributed among the mounting stages, and performing the component mounting distributed to the mounting stage to the one substrate stopped at the mounting stage; Component mounting is performed in the initial mounting mode for substrates whose transport order N (N is an integer of 1 or more) is less than M among the above, and for substrates whose transport order N is M or more, Component mounting in mounting mode In the initial mounting mode, regarding the substrate in transport order N, among the M mounting stages, the substrate is transferred to the mounting stage downstream of the (MN) -th mounting stage counted from the upstream side in the substrate transfer direction. Component mounting is selectively distributed, and the substrate passes through the (M−N) th mounting stage, and a plurality of mounting targets of the substrate are mounted in the mounting stage downstream of the (M−N) th mounting stage Component mounting to a point is performed. In the normal mounting mode, component mounting to the substrate is distributed to each of the M mounting stages, and the substrate is sequentially stopped to the M mounting stages, and M mounting stages are performed. Component mounting to a plurality of mounting target points of the substrate is sequentially performed in each of the above.
 このように構成された本発明(部品実装システム、部品実装方法)では、一の基板に設けられた複数の実装対象点に対する部品実装がM個の実装ステージの間で分配される。そして、当該一の基板を基板搬送方向に搬送しつつM個の実装ステージのうち部品実装を分配した実装ステージに停止させて、実装ステージで停止する当該一の基板に対して実装ステージに分配された部品実装が実行される。この際、L枚の基板のうち基板搬送方向への搬送順序NがM未満の基板に対しては初期実装モードで部品実装が実行され、搬送順序NがM以上の基板に対しては通常実装モードで部品実装が実行される。初期実装モードでは、搬送順序Nの基板に関して、M個の実装ステージのうち基板搬送方向の上流側から数えて(M-N)番目の実装ステージよりも下流側の実装ステージに基板への部品実装が選択的に分配され、基板は(M-N)番目までの実装ステージを通過して、(M-N)番目の実装ステージよりも下流側の実装ステージで基板の複数の実装対象点への部品実装が実行される。一方、通常実装モードでは、M個の実装ステージのそれぞれに基板への部品実装が分配され、基板はM個の実装ステージに順番に停止して、M個の実装ステージのそれぞれで順番に基板の複数の実装対象点への部品実装が実行される。 In the present invention (component mounting system, component mounting method) configured as described above, component mounting for a plurality of mounting target points provided on one substrate is distributed among M mounting stages. Then, the one of the M mounting stages is stopped at the mounting stage to which the component mounting is distributed while being transported in the substrate transfer direction, and the one board stopped at the mounting stage is distributed to the mounting stage. Component mounting is performed. At this time, component mounting is performed in the initial mounting mode on a substrate having a transport order N of less than M in the substrate transport direction among the L substrates, and the normal mounting is performed on a substrate having a transport order N of M Component mounting is performed in the mode. In the initial mounting mode, with respect to the substrate in transport order N, component mounting on the substrate at the mounting stage downstream of the (M−N) th mounting stage counted from the upstream side of the substrate transport direction among the M mounting stages Are selectively distributed, the substrate passes through the (M−N) th mounting stage, and the mounting target points on the substrate at the mounting stage downstream of the (M−N) th mounting stage Component mounting is performed. On the other hand, in the normal mounting mode, component mounting on the substrate is distributed to each of the M mounting stages, the substrate is sequentially stopped at the M mounting stages, and the substrate is sequentially printed on each of the M mounting stages. Component mounting to a plurality of mounting points is performed.
 したがって、L枚の基板のうち搬送順序が最初のM枚の基板については、次のようにして部品実装が実行される。つまり、1番目から(M-1)番目の基板は、初期実装モードによって、基板搬送方向の上流側から数えてM番目から2番目の実装ステージに搬送され、M番目の基板は、通常実装モードによって、基板搬送方向の上流側から数えて1番目の実装ステージに搬送される。こうして、M個の実装ステージのそれぞれに基板を搬送して、各実装ステージで基板への部品実装を開始することができる。これによって、部品実装システムの稼働率の低下を抑制することが可能となっている。 Therefore, component mounting is performed as follows about M board | substrates whose conveyance order is the first among L board | substrates. That is, the first to the (M-1) th substrates are transported to the Mth to the second mounting stages counted from the upstream side in the substrate transport direction in the initial mounting mode, and the Mth substrate is in the normal mounting mode Thus, the substrate is transported to the first mounting stage counting from the upstream side in the substrate transport direction. Thus, the substrate can be transported to each of the M mounting stages, and component mounting on the substrate can be started at each mounting stage. This makes it possible to suppress a drop in the operation rate of the component mounting system.
 なお、本明細書では、I1番目からI2番目との表記(I1、I2は1以上の整数である)において、I1とI2とが等しい場合には、当該表記はI1番目を示すものとする。 In the present specification, in the notation of I1 to I2 (I1 and I2 are integers of 1 or more), when I1 and I2 are equal, the notation indicates I1.
 また、搬送部は、基板搬送方向に隣り合う実装ステージの間に配置された待機ステージをさらに有し、基板搬送方向において、M個の実装ステージのうち、最下流の実装ステージ以外の実装ステージは、下流側で隣り合う実装ステージで部品実装が実行する場合には、分配された部品実装が完了した基板を下流側の待機ステージに搬出して、分配された実装対象点への部品実装が未完の基板を基板搬送方向の上流側から搬入するように、部品実装システムを構成しても良い。かかる構成では、最下流の実装ステージ以外の実装ステージは、分配された部品実装が完了した基板を速やかに待機ステージに搬出して、部品実装が未完の次の基板を基板搬送方向の上流側から搬入することができる。その結果、部品実装システムの稼働率の低下をより効果的に抑制することが可能となっている。 The transport unit further includes a standby stage disposed between the mounting stages adjacent in the substrate transport direction, and among the M mounting stages in the substrate transport direction, the mounting stages other than the most downstream mounting stage are When the component mounting is performed at the downstream mounting stage adjacent to each other, the distributed component mounting completed substrate is carried out to the downstream standby stage, and the component mounting to the distributed mounting target point is incomplete. The component mounting system may be configured to carry in the substrate from the upstream side in the substrate transfer direction. In this configuration, the mounting stages other than the most downstream mounting stage promptly carry out the distributed component mounting completed substrate onto the standby stage, and the next substrate whose component mounting is incomplete is taken from the upstream side of the substrate transport direction It can be carried in. As a result, it is possible to more effectively suppress the decrease in the operation rate of the component mounting system.
 また、通常実装モードでは、実装ステージのそれぞれで部品が実装される実装対象点の個数の差が1個以下となるように、M個の実装ステージのそれぞれに基板への部品実装が分配され、初期実装モードでは、搬送順序Nの基板に関して、基板搬送方向の上流側から数えて(M-N+1)番目の実装ステージには、通常実装モードで基板搬送方向の上流側から数えて1番目から(M-N+1)番目までの実装ステージに分配される部品実装が分配されるように、部品実装システムを構成しても良い。かかる構成では、仮に搬送順序NがM未満の基板に対して通常実装モードを実行した場合に、基板搬送方向の上流側から数えて1番目から(M-N+1)番目までの実装ステージに分配される部品実装が、初期実装モードにおいて当該(M-N+1)番目の実装ステージに分配される。つまり、初期実装モードでは、搬送順序Nの基板に関して、(M-N+1)番目の実装ステージより上流側の実装ステージでの部品実装が省略されるものの、この部品実装を(M-N+1)番目の実装ステージで確実に実行することが可能となっている。 In the normal mounting mode, component mounting on the substrate is distributed to each of the M mounting stages such that the difference in the number of mounting target points on which components are mounted in each of the mounting stages is less than or equal to one, In the initial mounting mode, the (M−N + 1) th mounting stage counted from the upstream side in the substrate conveyance direction with respect to the substrate in the conveyance order N is counted from the first from the upstream side in the substrate conveyance direction in the normal mounting mode The component mounting system may be configured such that component mounting distributed to the (M−N + 1) th mounting stages is distributed. In this configuration, if the normal mounting mode is executed for a substrate whose transport order N is less than M, it is distributed to the first to (M−N + 1) th mounting stages counted from the upstream side in the substrate transport direction. Component mounting is distributed to the (M−N + 1) th mounting stage in the initial mounting mode. That is, in the initial mounting mode, with respect to the substrate in transport order N, component mounting at the mounting stage on the upstream side of the (M−N + 1) th mounting stage is omitted, but this component mounting is the (M−N + 1) th It is possible to execute reliably at the implementation stage.
 また、制御部は、L枚の基板のうち搬送順序Nが(L-M+2)番以上の基板に対しては終期実装モードで部品実装を実行し、終期実装モードでは、搬送順序Nの基板に関して、M個の実装ステージのうち基板搬送方向の上流側から数えて1番目から(L-N+1)番目までの実装ステージに基板への部品実装が選択的に分配され、1番目から(L-N+1)番目までの実装ステージで基板の複数の実装対象点への部品実装が実行されるように、部品実装システムを構成しても良い。かかる構成では、L枚の基板のうち搬送順序Nが(L-M+2)番以上の基板に対しては、M個の実装ステージのうち基板搬送方向の上流側から数えて1番目から(L-N+1)番目までの実装ステージに基板への部品実装が選択的に分配され、1番目から(L-N+1)番目までの実装ステージで基板の複数の実装対象点への部品実装が実行される。したがって、基板搬送方向において、(L-N+1)番目より下流側の実装ステージで部品実装を実行中であっても、1番目から(L-N+1)番目までの実装ステージを稼動させて、搬送順序Nが(L-M+2)番以上の基板に対して部品実装を効率的に実行できる。その結果、部品実装システムの稼働率の低下をより効果的に抑制することが可能となっている。 In addition, the control unit executes component mounting in the final mounting mode for substrates having a transportation order N of (L−M + 2) or more among the L substrates, and in the final mounting mode, the substrate for the transportation order N is The component mounting on the substrate is selectively distributed to the first to (L-N + 1) th mounting stages counted from the upstream side of the substrate transfer direction among the M mounting stages, and from the first to (L-N + 1) The component mounting system may be configured such that component mounting to a plurality of mounting target points of the substrate is performed at the first to the third mounting stages. In such a configuration, among the L substrates, for the substrate having the transport order N of (L−M + 2) or more, the first of the M mounting stages, counting from the upstream side in the substrate transport direction, Component mounting on the substrate is selectively distributed to the (N + 1) th mounting stages, and component mounting to a plurality of mounting target points of the substrate is performed in the first to (L−N + 1) th mounting stages. Therefore, even while component mounting is being performed at the mounting stage downstream of the (L−N + 1) th in the substrate carrying direction, the first to (L−N + 1) th mounting stages are operated, and the carrying order is increased. Component mounting can be efficiently performed on a substrate where N is (L−M + 2) or more. As a result, it is possible to more effectively suppress the decrease in the operation rate of the component mounting system.
 また、通常実装モードでは、実装ステージのそれぞれで部品が実装される実装対象点の個数の差が1個以下となるように、M個の実装ステージのそれぞれに基板への部品実装が分配され、終期実装モードでは、搬送順序Nの基板に関して、基板搬送方向の上流側から数えて(L-N+1)番目の実装ステージには、通常実装モードで基板搬送方向の上流側から数えて(L-N+1)番目からM番目までの実装ステージに分配される部品実装が分配されるように、部品実装システムを構成しても良い。かかる構成では、仮に搬送順序Nが(L-M+2)番以上の基板に対して通常実装モードを実行した場合に、基板搬送方向の上流側から数えて(L-N+1)番目からM番目までの実装ステージに分配される部品実装が、終期実装モードにおいて当該(L-N+1)番目の実装ステージに分配される。つまり、終期実装モードでは、搬送順序Nの基板に関して、(L-N+1)番目の実装ステージより下流側の実装ステージでの部品実装が省略されるものの、この部品実装を(L-N+1)番目の実装ステージで確実に実行することが可能となっている。 In the normal mounting mode, component mounting on the substrate is distributed to each of the M mounting stages such that the difference in the number of mounting target points on which components are mounted in each of the mounting stages is less than or equal to one, In the final mounting mode, with respect to the substrate in the conveyance order N, counting from the upstream side of the substrate conveyance direction from the upstream side in the substrate conveyance direction, counting from the upstream side of the substrate conveyance direction in the normal mounting mode (L-N + 1) The component mounting system may be configured such that component mounting distributed to the first to Mth mounting stages is distributed. In this configuration, if the normal mounting mode is executed for a substrate having a transport order N of (L−M + 2) or more, the (L−N + 1) th to the Mth from the upstream side in the substrate transport direction are counted. The component mounting distributed to the mounting stage is distributed to the (L−N + 1) th mounting stage in the final mounting mode. That is, in the final mounting mode, with respect to the substrate in transport order N, component mounting at the mounting stage downstream of the (L−N + 1) th mounting stage is omitted, but this component mounting is the (L−N + 1) th It is possible to execute reliably at the implementation stage.
 また、制御部は、通常実装モードにおいて、M個の実装ステージのうち、一の実装ステージおよび他の実装ステージの少なくとも一方での部品実装の進捗に応じて、一の実装ステージと他の実装ステージとの間での部品実装の分配を調整するように、部品実装システムを構成しても良い。かかる構成では、一の実装ステージでの部品実装の進捗が例えば予定より遅い場合に、一の実装ステージに分配予定であった部品実装を他の実装ステージに分配するといったことができる。 In addition, the control unit, in the normal mounting mode, one mounting stage and the other mounting stage according to the progress of component mounting in at least one of the one mounting stage and the other mounting stage among the M mounting stages. The component mounting system may be configured to adjust the distribution of component mounting among the components. In such a configuration, when the progress of component mounting in one mounting stage is, for example, later than scheduled, it is possible to distribute the component mounting to be distributed to one mounting stage to another mounting stage.
 本発明によれば、複数の実装ステージが基板搬送方向に並ぶ部品実装システムにおいて、部品実装システムの稼働率の低下を抑制することが可能となる。 According to the present invention, in the component mounting system in which a plurality of mounting stages are arranged in the substrate transfer direction, it is possible to suppress a decrease in operation rate of the component mounting system.

 図1は本発明に係る部品実装システムの一例を模式的に示す平面図である。図1に示すように、本明細書では、基板搬送方向X、幅方向Yおよび鉛直方向Zで構成されるXYZ直交座標軸を適宜用いる。基板搬送方向Xおよび幅方向Yは水平方向に並行であるとともに互いに直交し、鉛直方向Zは基板搬送方向Xおよび幅方向Yに直交する。 FIG. 1 is a plan view schematically showing an example of a component mounting system according to the present invention. As shown in FIG. 1, in the present specification, XYZ orthogonal coordinate axes configured of a substrate conveyance direction X, a width direction Y, and a vertical direction Z are appropriately used. The substrate transport direction X and the width direction Y are parallel to the horizontal direction and orthogonal to each other, and the vertical direction Z is orthogonal to the substrate transport direction X and the width direction Y.
 この部品実装システム1は、基板搬送方向Xの上流側から搬入された基板Bに対して部品を実装して基板搬送方向Xの下流側に搬出する1台の部品実装機10により構成される。基板Bには複数の実装対象点Bpが設けられており、部品実装機10に具備された制御部100は、部品実装機10の各部を制御することで、各実装対象点Bpに部品Wpを1個ずつ実装する。ここで、各部品WpはダイシングされたウェハーWのベアチップであり、互いに同一の構成を有する。 The component mounting system 1 is configured of one component mounter 10 which mounts components on the substrate B carried in from the upstream side in the substrate conveyance direction X and carries it out downstream in the substrate conveyance direction X. A plurality of mounting target points Bp are provided on the substrate B, and the control unit 100 provided in the component mounting machine 10 controls the respective components of the component mounting machine 10 to place the component Wp on each mounting target point Bp. Implement one by one. Here, each component Wp is a bare chip of the diced wafer W and has the same configuration.
 この部品実装機10は基板搬送方向Xに基板Bを搬送する搬送部2を備える。搬送部2は、基板搬送方向Xにこの順番で並ぶ、待機コンベア21、実装コンベア22、待機コンベア23、実装コンベア24および搬出コンベア25を有し、これらのコンベア21~25が協働して基板搬送方向Xに基板Bを搬送することができる。待機コンベア21は、部品実装システム1の外部から搬入した基板Bを待機させ、あるいは実装コンベア22に受け渡す。実装コンベア22は待機コンベア21の基板搬送方向Xの下流側に位置する実装位置Pm1に対して設けられ、待機コンベア21から受け取った基板Bを実装位置Pm1に固定し、あるいは待機コンベア23に受け渡す。待機コンベア23は実装位置Pm1の基板搬送方向Xの下流側に位置する待機位置Pwに対して設けられ、実装コンベア22から受け取った基板Bを待機位置Pwで待機させ、あるいは実装コンベア24に受け渡す。実装コンベア24は待機位置Pwの基板搬送方向Xの下流側に位置する実装位置Pm2に対して設けられ、待機コンベア23から受け取った基板Bを実装位置Pm2に固定し、あるいは搬出コンベア25に受け渡す。搬出コンベア25は実装位置Pm2の基板搬送方向Xの下流側の位置に対して設けられ、実装コンベア24から受け取った基板Bを部品実装システム1の外部へ搬出する。このように、搬送部2では、M個の実装位置Pm1、Pm2が基板搬送方向Xに並んで設けられており、基板搬送方向Xに隣り合う実装位置Pm1、Pm2の間に待機位置Pwが配置されている。ここで、Mは2以上の整数で、図1の例ではM=2である。なお、以下では、実装位置Pm1、Pm2を区別しない場合には、実装位置Pmと称する。 The component mounter 10 includes a transport unit 2 that transports the substrate B in the substrate transport direction X. The transport unit 2 has a standby conveyor 21, a mounting conveyor 22, a standby conveyor 23, a mounting conveyor 24, and an unloading conveyor 25 arranged in this order in the substrate conveyance direction X, and these conveyors 21 to 25 cooperate with each other to The substrate B can be transported in the transport direction X. The standby conveyor 21 causes the substrate B carried in from the outside of the component mounting system 1 to stand by, or delivers the substrate B to the mounting conveyor 22. The mounting conveyor 22 is provided for the mounting position Pm1 located on the downstream side of the substrate conveyance direction X of the standby conveyor 21 and fixes the substrate B received from the standby conveyor 21 to the mounting position Pm1 or delivers it to the standby conveyor 23 . The standby conveyor 23 is provided for the standby position Pw located downstream of the mounting position Pm1 in the substrate transfer direction X, and makes the substrate B received from the mounting conveyor 22 stand by at the standby position Pw or delivers it to the mounting conveyor 24 . The mounting conveyor 24 is provided for the mounting position Pm2 located downstream of the standby position Pw in the substrate transfer direction X, and fixes the substrate B received from the standby conveyor 23 to the mounting position Pm2 or delivers it to the unloading conveyor 25 . The unloading conveyor 25 is provided at a position downstream of the mounting position Pm 2 in the substrate transfer direction X, and discharges the substrate B received from the mounting conveyor 24 to the outside of the component mounting system 1. Thus, in the transport unit 2, M mounting positions Pm 1 and Pm 2 are provided side by side in the substrate transport direction X, and the standby position Pw is disposed between the mount positions Pm 1 and Pm 2 adjacent in the substrate transport direction X It is done. Here, M is an integer of 2 or more, and in the example of FIG. 1, M = 2. Hereinafter, when the mounting positions Pm1 and Pm2 are not distinguished from one another, they will be referred to as mounting positions Pm.
 また、部品実装機10は部品Wpを供給する部品供給機構3を備える。部品供給機構3は、複数のウェハーWを収納可能なウェハー収納部31と、ウェハー収納部31からウェハー供給位置PpまでウェハーWを引き出すウェハー引出部33とを有する。ウェハー収納部31は、それぞれウェハーWを保持する複数のウェハーホルダーWhを鉛直方向Zに並べて収納するラックを鉛直方向Zに昇降させることで、ウェハー引出部33がウェハーWを受取可能な高さにウェハーホルダーWhを位置させて、このウェハーホルダーWhをウェハー引出部33に押し出すことができる。 The component mounter 10 further includes a component supply mechanism 3 for supplying the component Wp. The component supply mechanism 3 has a wafer storage unit 31 capable of storing a plurality of wafers W, and a wafer extraction unit 33 for extracting the wafer W from the wafer storage unit 31 to the wafer supply position Pp. The wafer storage unit 31 arranges a plurality of wafer holders Wh for holding the wafers W in the vertical direction Z and raises and lowers a rack for storing the wafers W at a height at which the wafer lead-out unit 33 can receive the wafers W. The wafer holder Wh can be pushed out to the wafer drawing portion 33 by positioning the wafer holder Wh.
 ウェハー引出部33は、ウェハーホルダーWhを支持するウェハー支持テーブル331と、ウェハー支持テーブル331を幅方向Yに移動可能に支持する固定レール332と、幅方向Yに設けられてウェハー支持テーブル331に取り付けられたボールネジ333と、ボールネジ333を駆動するY軸モーター334とを有する。したがって、Y軸モーター334によりボールネジ333を回転させることで、ウェハー支持テーブル331を固定レール332に沿って幅方向Yに移動させることができる。なお、図1に示すように、ウェハー収納部31とウェハー供給位置Ppとは搬送部2を幅方向Yから挟むように配置されており、ウェハー支持テーブル331は搬送部2の下方を通過する。かかるウェハー支持テーブル331は、ウェハー収納部31に隣接する受取位置でウェハー収納部31からウェハーホルダーWhを受け取って、受取位置よりウェハー収納部31から幅方向Yに離れたウェハー供給位置Ppへと移動することで、ウェハー供給位置PpにウェハーWを引き出す。 The wafer lead-out portion 33 includes a wafer support table 331 supporting the wafer holder Wh, a fixed rail 332 supporting the wafer support table 331 movably in the width direction Y, and is provided in the width direction Y and attached to the wafer support table 331 And a Y-axis motor 334 for driving the ball screw 333. Therefore, the wafer support table 331 can be moved in the width direction Y along the fixed rail 332 by rotating the ball screw 333 by the Y-axis motor 334. As shown in FIG. 1, the wafer storage unit 31 and the wafer supply position Pp are disposed so as to sandwich the transfer unit 2 in the width direction Y, and the wafer support table 331 passes below the transfer unit 2. The wafer support table 331 receives the wafer holder Wh from the wafer storage unit 31 at the reception position adjacent to the wafer storage unit 31 and moves from the reception position to the wafer supply position Pp away from the wafer storage unit 31 in the width direction Y. Thus, the wafer W is pulled out to the wafer supply position Pp.
 さらに、部品供給機構3は、ウェハー供給位置Ppから部品Wpを取り出す部品取出部35を有する。部品取出部35は、ウェハー供給位置Ppから部品Wpを取り出す取出ヘッド36を有し、取出ヘッド36をXY方向に駆動可能である。つまり、部品取出部35は、取出ヘッド36を基板搬送方向Xに移動可能に支持する支持部材351と、基板搬送方向Xに設けられて取出ヘッド36に取り付けられたボールネジを駆動するX軸モーター352とを有し、X軸モーター352によりボールネジを駆動することで、取出ヘッド36を基板搬送方向Xに移動させることができる。また、部品取出部35は、支持部材351を幅方向Yに移動可能に支持する固定レール353と、幅方向Yに設けられて固定レール353に取り付けられたボールネジ354と、ボールネジ354を駆動するY軸モーター355とを有する。したがって、Y軸モーター355によりボールネジ354を駆動することで、支持部材351とともに取出ヘッド36を幅方向Yに移動させることができる。 Furthermore, the component supply mechanism 3 has a component extraction unit 35 for extracting the component Wp from the wafer supply position Pp. The component pickup unit 35 has a pickup head 36 for picking up the component Wp from the wafer supply position Pp, and can drive the pickup head 36 in the X and Y directions. That is, the component pickup unit 35 supports the support member 351 for supporting the pickup head 36 movably in the substrate conveyance direction X, and the X-axis motor 352 for driving a ball screw provided in the substrate conveyance direction X and attached to the pickup head 36. The take-out head 36 can be moved in the substrate transfer direction X by driving the ball screw by the X-axis motor 352. The component pick-up portion 35 also drives a fixed rail 353 for supporting the support member 351 so as to be movable in the width direction Y, a ball screw 354 provided in the width direction Y and attached to the fixed rail 353, and Y for driving the ball screw 354. And an axial motor 355. Therefore, by driving the ball screw 354 by the Y-axis motor 355, the take-out head 36 can be moved in the width direction Y together with the support member 351.
 取出ヘッド36は、基板搬送方向Xに延設されたブラケット361と、ブラケット361に回転可能に支持された2個のノズル362とを有する。各ノズル362は、基板搬送方向Xに平行な回転軸を中心に回転することで、下方を向く吸着位置および上方を向く受渡位置(図1の位置)のいずれかに位置する。また、ブラケット361は、各ノズル362を伴って昇降可能である。 The takeout head 36 has a bracket 361 extending in the substrate transport direction X, and two nozzles 362 rotatably supported by the bracket 361. Each nozzle 362 is positioned at either the suction position facing downward or the delivery position facing upward (position in FIG. 1) by rotating around a rotation axis parallel to the substrate transfer direction X. In addition, the bracket 361 can move up and down with each nozzle 362.
 かかる部品供給機構3は、吸着位置に位置させたノズル362を、ウェハー供給位置Pp上の部品Wpに上方から対向させると、ノズル362を下降させて部品Wpに接触させる。さらに、部品供給機構3はノズル362に負圧を与えつつノズル362を上昇させることで、ウェハー供給位置Ppから部品Wpを吸着する。そして、部品供給機構3は、ノズル362を受渡位置に位置させることで、部品Wpを供給する。 When the nozzle 362 located at the suction position faces the component Wp on the wafer supply position Pp from the upper side, the component supply mechanism 3 lowers the nozzle 362 to contact the component Wp. Furthermore, the component supply mechanism 3 sucks the component Wp from the wafer supply position Pp by raising the nozzle 362 while applying a negative pressure to the nozzle 362. Then, the component supply mechanism 3 supplies the component Wp by positioning the nozzle 362 at the delivery position.
 部品実装機10は、こうして部品供給機構3によって供給された部品Wpを基板Bに実装する実装部4A、4Bを備える。特にM個の実装位置Pm1、Pm2に対して一対一の対応関係で、M個の実装部4A、4Bが設けられている(上述の通り、図1の例ではM=2である)。つまり、実装部4Aは、実装位置Pm1に対応して設けられ、実装部4Bは、実装位置Pm2に対応して設けられている。実装部4A、4Bは、部品実装機10の天井に幅方向Yに設けられた固定レールに沿って移動可能な支持部材41と、支持部材41によって基板搬送方向Xに移動可能に支持された実装ヘッド42とを有し、実装ヘッド42をXY方向に移動させることができる。実装ヘッド42は、下方を向く2個のノズル421を有する。 The component mounter 10 includes mounting portions 4A and 4B for mounting the component Wp thus supplied by the component supply mechanism 3 on the substrate B. In particular, M mounting portions 4A and 4B are provided in a one-to-one correspondence with M mounting positions Pm1 and Pm2 (as described above, M = 2 in the example of FIG. 1). That is, the mounting unit 4A is provided corresponding to the mounting position Pm1, and the mounting unit 4B is provided corresponding to the mounting position Pm2. The mounting portions 4A and 4B are mounted so as to be movable in the substrate transfer direction X by the support member 41 movable along the fixed rail provided in the width direction Y on the ceiling of the component mounter 10 and the support member 41 The mounting head 42 can be moved in the X and Y directions. The mounting head 42 has two nozzles 421 facing downward.
 部品Wpの吸着・実装に際しては、実装部4A、4Bそれぞれは、取出ヘッド36の上方に移動して、受渡位置に位置するノズル362に保持される部品Wpに対してノズル421を上方から対向させると、ノズル421を下降させて部品Wpに接触させる。続いて、部品供給機構3がノズル362の負圧を解除するとともに、実装部4A、4Bがノズル421に負圧を与えつつノズル421を上昇させる。こうして実装ヘッド42によって部品Wpを吸着すると、実装部4Aは、対応する実装位置Pm1に固定された基板Bの実装対象点Bpに部品Wpを実装し、実装部4Bは、対応する実装位置P4に固定された基板Bの実装対象点Bpに部品Wpを実装する。このように、実装部4A、4Bは、単一種類の部品Wpを基板Bに実装する。なお、以下では、実装部4A、4Bを区別しない場合には、実装部4と称する。 At the time of suction and mounting of the component Wp, each of the mounting portions 4A and 4B moves above the takeout head 36 and makes the nozzle 421 face the component Wp held by the nozzle 362 located at the delivery position from above. And the nozzle 421 is lowered to contact the part Wp. Subsequently, the component supply mechanism 3 releases the negative pressure of the nozzle 362, and the mounting portions 4A and 4B raise the nozzle 421 while applying a negative pressure to the nozzle 421. Thus, when the component Wp is absorbed by the mounting head 42, the mounting unit 4A mounts the component Wp on the mounting target point Bp of the substrate B fixed at the corresponding mounting position Pm1, and the mounting unit 4B corresponds to the corresponding mounting position P4. The component Wp is mounted on the mounting target point Bp of the fixed substrate B. Thus, the mounting units 4A and 4B mount the single type of component Wp on the substrate B. Hereinafter, when the mounting units 4A and 4B are not distinguished from one another, they will be referred to as the mounting unit 4.
 かかる部品実装システム1では、制御部100は、実装位置Pm1、Pm2において基板Bに部品実装を実行することができる。この際、制御部100は、一の基板Bに設けられた複数の実装対象点Bpに対する部品実装をM個の実装位置Pm1、Pm2の間で分配する(換言すれば、分担させる)。つまり、搬送部2は、当該一の基板Bを基板搬送方向Xに搬送しつつ、M個の実装位置Pm1、Pm2のうち部品実装が分配された実装位置Pmに停止させる。そして、実装部4は、対応する実装位置Pmで停止する当該一の基板Bに対して、対応する実装位置Pmに分配された部品実装を実行する。 In the component mounting system 1, the control unit 100 can perform component mounting on the substrate B at the mounting positions Pm1 and Pm2. Under the present circumstances, the control part 100 distributes component mounting with respect to several mounting object point Bp provided in the one board | substrate B among M mounting position Pm1 and Pm2 (in other words, it makes share). That is, the transport unit 2 stops the one of the M mounting positions Pm1 and Pm2 at the mounting position Pm at which the component mounting is distributed, while transporting the one substrate B in the substrate transport direction X. And the mounting part 4 performs component mounting distributed to the corresponding mounting position Pm with respect to the said one board | substrate B which stops at the corresponding mounting position Pm.
 通常は、制御部100は、基板Bの複数の実装対象点Bpのうち、基板搬送方向Xの上流側半分の実装対象点Bpの部品実装を実装位置Pm1に分配し、基板搬送方向Xの下流側半分の実装対象点Bpの部品実装を実装位置Pm2に分配する(通常実装モード)。具体的には、搬送部2は一の基板Bを実装位置Pm1に搬送して、実装部4Aが実装位置Pm1に停止する基板Bの基板搬送方向Xの上流側半分の実装対象点Bp(通常分配点)に部品Wpを実装する。実装位置Pm1での部品実装が完了すると、搬送部2は、基板Bを実装位置Pm1から実装位置Pm2に搬送して、実装部4Bが実装位置Pm2に停止する基板Bの基板搬送方向Xの下流側半分の実装対象点Bp(通常分配点)に部品Wpを実装する。つまり、通常実装モードは、一の基板Bを実装位置Pm1、Pm2に順番に停止させて、各実装位置Pm1、Pm2に停止する一の基板Bに対して各実装位置Pm1、Pm2に分配された部品実装を実行する。そして、制御部100は、複数の基板Bを基板搬送方向Xに順番に搬送しつつ、各基板Bに対して通常実装モードを実行することができる。 Normally, the control unit 100 distributes the component mounting of the mounting target point Bp on the upstream half of the substrate conveying direction X among the plurality of mounting target points Bp on the substrate B to the mounting position Pm1, and the downstream of the substrate conveying direction X The component mounting of the mounting target point Bp on the side half is distributed to the mounting position Pm2 (normal mounting mode). Specifically, the transport unit 2 transports the one substrate B to the mounting position Pm1, and the mounting target point Bp on the upstream half of the substrate transport direction X of the substrate B at which the mounting unit 4A stops at the mounting position Pm1 Mount the component Wp at the distribution point). When the component mounting at the mounting position Pm1 is completed, the transport unit 2 transports the substrate B from the mounting position Pm1 to the mounting position Pm2, and the downstream of the substrate transport direction X of the substrate B where the mounting portion 4B stops at the mounting position Pm2. The component Wp is mounted on the mounting target point Bp (normal distribution point) on the side half. That is, in the normal mounting mode, one substrate B is stopped at the mounting positions Pm1 and Pm2 in order, and one substrate B stopping at each mounting position Pm1 and Pm2 is distributed to the mounting positions Pm1 and Pm2 Execute component mounting. Then, the control unit 100 can execute the normal mounting mode on each of the substrates B while sequentially transporting the plurality of substrates B in the substrate transport direction X.
 ただし、制御部100は、L枚(LはMより大きい整数)の基板Bを順番に搬送部2により搬送しつつ各基板Bに部品実装を実行するにあたっては、基板Bの搬送順序Nに応じて実装位置Pm1、Pm2への部品実装の分配を動的に変更する。図2~図4を用いて、この点を詳述する。なお、以下では、基板搬送方向Xの下流あるいは上流を単に「下流」あるいは「上流」と適宜称する。 However, in order to carry out component mounting on each substrate B while conveying L substrates (L is an integer larger than M) of the substrates B in order by the control unit 100, the conveyance order N of the substrates B is used. Dynamically change the distribution of component mounting to the mounting positions Pm1 and Pm2. This point will be described in detail with reference to FIGS. In the following, the downstream or upstream of the substrate transport direction X is simply referred to as “downstream” or “upstream” as appropriate.
 図2は基板を基板搬送方向に搬送しつつ基板に部品実装を実行するに際して実行される搬入時判断処理の一例を示すフローチャートであり、図3は基板搬送方向に搬送しつつ基板に部品実装を実行するに際して実行される実装完了時判断処理の一例を示すフローチャートであり、図4は図2および図3のフローチャートに従って実行される動作の第1例を模式的に示す図である。図4では、4枚(すなわち、L=4)の基板Bを基板搬送方向Xに順番に搬送しつつ、各基板Bに部品実装を実行する例が示されている。また、図4では、L枚の基板Bの搬送順序N(N=1~4)が符号Bに付されている。 FIG. 2 is a flow chart showing an example of a carrying-in determination process performed when performing component mounting on a substrate while conveying the substrate in the substrate conveyance direction, and FIG. 3 is component mounting on the substrate while conveying in the substrate conveyance direction. FIG. 4 is a flow chart showing an example of an implementation completion determination process executed upon execution, and FIG. 4 is a view schematically showing a first example of an operation executed according to the flow charts of FIG. 2 and FIG. FIG. 4 shows an example in which component mounting is performed on each of the substrates B while the four substrates (that is, L = 4) are sequentially transported in the substrate transport direction X. Further, in FIG. 4, the transport order N (N = 1 to 4) of the L substrates B is attached to the reference symbol B.
 制御部100は、実装位置Pm1、Pm2のそれぞれについて図2および図3のフローチャートに示す搬入時・実装完了時判断処理を実行することで、図4の動作を実行する。1番目の基板B1の下流端が実装位置Pm1に搬入されると(図2のステップS101で「YES」)、基板B1の複数の実装対象点Bpのうちに、部品Wpが実装されていない未実装点が存在するかが判断される(ステップS102)。基板B1には未実装点が存在するため(ステップS102で「YES」)、ステップS103に進む。ステップS103では、本実装位置Pm1がM個の実装位置Pm1、Pm2のうち最下流の実装位置Pmであるかが判断される。実装位置Pm1は最下流の実装位置Pmでないため(ステップS103で「NO」)、ステップS104に進む。ステップS104では、本実装位置Pm1より下流の実装位置Pm2で、基板B1への部品実装を実行可能かが判断される。実装位置Pm2で部品実装を実行予定の基板Bは存在せず、実装位置Pm2が基板B1への部品実装を実行可能であるため(ステップS104で「YES」)、ステップS105へ進む。そして、ステップS105では、制御部100は、基板B1の部品実装を、本実装位置Pm1に分配せず、下流の実装位置Pm2に分配すると決定する。 The control unit 100 executes the operation of FIG. 4 by performing the carrying-in and mounting completion determination process shown in the flowcharts of FIGS. 2 and 3 for each of the mounting positions Pm1 and Pm2. When the downstream end of the first substrate B1 is carried to the mounting position Pm1 (“YES” in step S101 in FIG. 2), the component Wp is not mounted among the plurality of mounting target points Bp of the substrate B1. It is determined whether there is a mounting point (step S102). Since there is an unmounted point on the substrate B1 ("YES" in step S102), the process proceeds to step S103. In step S103, it is determined whether this mounting position Pm1 is the most downstream mounting position Pm among the M mounting positions Pm1 and Pm2. Since the mounting position Pm1 is not the most downstream mounting position Pm ("NO" in step S103), the process proceeds to step S104. In step S104, it is determined whether component mounting on the substrate B1 can be performed at the mounting position Pm2 downstream from the main mounting position Pm1. Since there is no board B scheduled to perform component mounting at the mounting position Pm2 and the mounting position Pm2 can execute component mounting on the board B1 ("YES" in step S104), the process proceeds to step S105. Then, in step S105, the control unit 100 determines not to distribute the component mounting of the substrate B1 to the main mounting position Pm1 but to distribute to the downstream mounting position Pm2.
 ステップS105での決定によって、基板B1は実装位置Pm1を通過して実装位置Pm2へ向けて搬送される。こうして基板B1の下流端が実装位置Pm2に搬入されると(ステップS101で「YES」)、基板B1の未実装点の存在が判断される(ステップS102)。基板B1には未実装点が存在するため(ステップS102で「YES」)、ステップS103で、本実装位置Pm2が最下流の実装位置Pmであるかが判断される。実装位置Pm2は最下流の実装位置Pmであるため(ステップS103で「YES」)、ステップS106へ進む。そして、ステップS106では、制御部100は、基板B1の部品実装を本実装位置Pm2に分配すると決定する。具体的には、基板B1が停止せずに通過した実装位置Pm1への通常分配点(上流側半分)と、基板B1の搬入先である実装位置Pm2への通常分配点(下流側半分)とに対する部品実装が、実装位置Pm2に分配される。これによって、図4の動作A101の欄に示すように、基板B1は実装位置Pm2に搬入され、基板B1の全実装対象点Bpへの部品実装が実装位置Pm2に分配される。 By the determination in step S105, the substrate B1 is transported to the mounting position Pm2 past the mounting position Pm1. When the downstream end of the substrate B1 is thus carried to the mounting position Pm2 ("YES" in step S101), the presence of an unmounted point of the substrate B1 is determined (step S102). Since there is an unmounted point on the substrate B1 ("YES" in step S102), it is determined in step S103 whether the main mounting position Pm2 is the most downstream mounting position Pm. Since the mounting position Pm2 is the most downstream mounting position Pm ("YES" in step S103), the process proceeds to step S106. Then, in step S106, the control unit 100 determines that the component mounting of the substrate B1 is to be distributed to the main mounting position Pm2. Specifically, the normal distribution point (upstream half) to the mounting position Pm1 through which the substrate B1 passes without stopping, and the normal distribution point (downstream half) to the mounting position Pm2 to which the substrate B1 is loaded The component mounting for is distributed to the mounting position Pm2. As a result, as shown in the column of operation A101 in FIG. 4, the substrate B1 is carried to the mounting position Pm2, and component mounting on all mounting target points Bp of the substrate B1 is distributed to the mounting position Pm2.
 2番目の基板B2の下流端が実装位置Pm1に搬入されると(ステップS101で「YES」)、ステップS102で基板B2に未実装点が存在する(YES)と判断され、さらにステップS103で本実装位置Pm1が最下流の実装位置Pmでない(NO)と判断され、ステップS104に進む。下流の実装位置Pm2では先の基板B1に部品実装を実行予定であるため、ステップS104では、実装位置Pm2では基板B2の部品実装を実装できない(NO)と判断され、ステップS106に進む。そして、ステップS106では、制御部100は、基板B2の部品実装を実装位置Pm1に分配すると決定する。これによって、図4の動作A101の欄に示すように、基板B2は実装位置Pm1に搬入され、基板B2の全実装対象点Bpのうち実装位置Pm1の通常分配点(上流側半分)への部品実装が実装位置Pm1に分配される。 When the downstream end of the second substrate B2 is carried to the mounting position Pm1 (“YES” in step S101), it is determined in step S102 that there is an unmounted point on the substrate B2 (YES), and further in step S103 It is determined that the mounting position Pm1 is not the most downstream mounting position Pm (NO), and the process proceeds to step S104. Since component mounting is scheduled to be performed on the previous board B1 at the downstream mounting position Pm2, in step S104 it is determined that the component mounting of the board B2 can not be mounted at the mounting position Pm2 (NO), and the process proceeds to step S106. Then, in step S106, the control unit 100 determines to distribute the component mounting of the substrate B2 to the mounting position Pm1. As a result, as shown in the column of operation A101 in FIG. 4, the substrate B2 is carried to the mounting position Pm1, and components to the normal distribution point (upstream half) of the mounting position Pm1 among all mounting target points Bp of the substrate B2 The mounting is distributed to the mounting position Pm1.
 そして、実装位置Pm2では、実装位置Pm1、Pm2への通常分配点への部品実装が1番目の基板B1に対して開始され、実装位置Pm1では、実装位置Pm1への通常分配点への部品実装が2番目の基板B2に対して開始される。図4の動作A102の欄に示すように、実装位置Pm1で分配された部品実装が基板B2に対して完了すると(ステップS201で「YES」)、基板B2に未実装点が存在するかが判断される(ステップS202)。基板B2の複数の実装対象点Bpのうち下流側半分には部品Wpが実装されていないため(ステップS202で「YES」)、ステップS203に進む。ステップS203では、実装位置Pm1の上流側、すなわち待機コンベア21に基板Bが存在するかが判断される。待機コンベア21には3番目の基板B3が存在するため(ステップS203で「YES」)、ステップS204に進む。ステップS204では、実装位置Pm1の下流側、すなわち待機位置Pwに基板Bが存在するかが判断される。待機位置Pwには基板Bが存在しないため(ステップS204で「NO」)、ステップS205に進む。そして、ステップS205では、基板B2が実装位置Pm1の下流、すなわち待機位置Pwに搬出され、基板B3の下流への搬送が開始される。 Then, at the mounting position Pm2, component mounting to the normal distribution point to the mounting positions Pm1 and Pm2 is started for the first board B1, and at the mounting position Pm1, component mounting to the normal distribution point to the mounting position Pm1 Is started for the second substrate B2. As shown in the column of operation A102 in FIG. 4, when the component mounting distributed at the mounting position Pm1 is completed on the substrate B2 ("YES" in step S201), it is determined whether there is an unmounted point on the substrate B2 (Step S202). Since the component Wp is not mounted on the downstream half of the plurality of mounting target points Bp of the substrate B2 ("YES" in step S202), the process proceeds to step S203. In step S203, it is determined whether the substrate B is present on the upstream side of the mounting position Pm1, that is, the standby conveyor 21. Since the third substrate B3 exists on the standby conveyor 21 ("YES" in step S203), the process proceeds to step S204. In step S204, it is determined whether the substrate B is present on the downstream side of the mounting position Pm1, ie, the standby position Pw. Since the substrate B does not exist at the standby position Pw ("NO" in step S204), the process proceeds to step S205. Then, in step S205, the substrate B2 is unloaded to the downstream of the mounting position Pm1, that is, to the standby position Pw, and the conveyance of the substrate B3 to the downstream is started.
 3番目の基板B3の下流端が実装位置Pm1に搬入されると(ステップS101で「YES」)、ステップS102で基板B3に未実装点が存在する(YES)と判断され、さらにステップS103で本実装位置Pm1が最下流の実装位置Pmでない(NO)と判断され、ステップS104に進む。下流の実装位置Pm2は先の基板B1に部品実装を実行中であるため、ステップS104では、実装位置Pm2では基板B3の部品実装を実装できない(NO)と判断され、ステップS106に進む。そして、ステップS106では、制御部100は、基板B3の部品実装を実装位置Pm1に分配すると決定する。これによって、図4の動作A103の欄に示すように、基板B3が実装位置Pm1に搬入され、基板B3の全実装対象点Bpのうち実装位置Pm1の通常分配点(上流側半分)への部品実装が実装位置Pm1に分配される。 When the downstream end of the third substrate B3 is carried to the mounting position Pm1 (“YES” in step S101), it is determined in step S102 that there is an unmounted point on the substrate B3 (YES), and further the step It is determined that the mounting position Pm1 is not the most downstream mounting position Pm (NO), and the process proceeds to step S104. Since component mounting is being performed on the previous board B1 at the downstream mounting position Pm2, in step S104, it is determined that the component mounting of the board B3 can not be mounted at the mounting position Pm2 (NO). Then, in step S106, the control unit 100 determines to distribute the component mounting of the substrate B3 to the mounting position Pm1. As a result, as shown in the column of operation A103 in FIG. 4, the board B3 is carried to the mounting position Pm1, and components to the normal distribution point (upstream half) of the mounting position Pm1 among all mounting target points Bp The mounting is distributed to the mounting position Pm1.
 そして、実装位置Pm1では、実装位置Pm1への通常分配点への部品実装が3番目の基板B3に対して開始される。図4の動作A104の欄に示すように、実装位置Pm2で分配された部品実装が基板B1に対して完了すると(図3のステップS201で「YES」)、基板B1に未実装点が存在するかが判断される(ステップS202)。基板B1の全実装対象点Bpに対して部品Wpが実装されているため(ステップS202で「NO」)、図4の動作A105の欄に示すように、基板B1が実装位置Pm2から下流へ搬出され、基板B2の下流への搬送が開始される(ステップS205)。 Then, at the mounting position Pm1, component mounting to the normal distribution point to the mounting position Pm1 is started for the third substrate B3. As shown in the column of operation A104 in FIG. 4, when the component mounting distributed at the mounting position Pm2 is completed on the substrate B1 (“YES” in step S201 in FIG. 3), an unmounted point exists on the substrate B1. A decision is made (step S202). Since the component Wp is mounted on all mounting target points Bp of the substrate B1 ("NO" in step S202), the substrate B1 is unloaded downstream from the mounting position Pm2, as shown in the column of the operation A105 in FIG. And transport of the substrate B2 to the downstream is started (step S205).
 また、図4の動作A104の欄に示すように、実装位置Pm1で分配された部品実装が基板B3に対して完了すると(ステップS201で「YES」)、基板B3に未実装点が存在するかが判断される(ステップS202)。基板B3の複数の実装対象点Bpのうち下流側半分に部品Wpが実装されていないため(ステップS202で「YES」)、実装位置Pm1の上流側、すなわち待機コンベア21に基板Bが存在するかが判断される(ステップS203)。待機コンベア21には4番目の基板B4が存在するため(ステップS203で「YES」)、ステップS204に進む。ステップS204では、実装位置Pm1の下流側、すなわち待機位置Pwに基板Bが存在するかが判断される。実装位置Pm2から基板B1が搬出されるのに伴って待機位置Pwから基板B2が搬出されるため、ステップS204では、待機位置Pwには基板Bが存在しない(NO)と判断され、ステップS205に進む。そして、図4の動作A105の欄に示すように、基板B3が実装位置Pm1から待機位置Pwに搬出されるとともに、基板B4の下流への搬送が開始される(ステップS205)。 In addition, as shown in the column of operation A104 in FIG. 4, if the component mounting distributed at the mounting position Pm1 is completed on the substrate B3 (“YES” in step S201), is there an unmounted point on the substrate B3? Is determined (step S202). Since the component Wp is not mounted on the downstream half of the plurality of mounting target points Bp of the substrate B3 (“YES” in step S202), is the substrate B present on the upstream side of the mounting position Pm1, ie, the standby conveyor 21? Is determined (step S203). Since the fourth substrate B4 exists in the standby conveyor 21 ("YES" in step S203), the process proceeds to step S204. In step S204, it is determined whether the substrate B is present on the downstream side of the mounting position Pm1, ie, the standby position Pw. Since the substrate B2 is unloaded from the standby position Pw as the substrate B1 is unloaded from the mounting position Pm2, in step S204, it is determined that the substrate B does not exist at the standby position Pw (NO), and the process proceeds to step S205. move on. Then, as shown in the column of operation A105 in FIG. 4, the substrate B3 is unloaded from the mounting position Pm1 to the standby position Pw, and conveyance of the substrate B4 to the downstream is started (step S205).
 基板B2の下流端が実装位置Pm2に搬入されると(ステップS101で「YES」)、基板B2の未実装点の存在が判断される(ステップS102)。基板B2の複数の実装対象点Bpのうち下流側半分には部品Wpが実装されていないため(ステップS102で「YES」)、ステップS103で、本実装位置Pm2が最下流の実装位置Pmであるかが判断される。実装位置Pm2は最下流の実装位置Pmであるため(ステップS103で「YES」)、ステップS106へ進む。そして、ステップS106では、制御部100は、基板B2の未実装点への部品実装を本実装位置Pm2に分配すると決定する。これによって、図4の動作A105の欄に示すように、基板B2が実装位置Pm2に搬入され、基板B2の全実装対象点Bpのうち実装位置Pm2の通常分配点(下流側半分)への部品実装が実装位置Pm2に分配される。 When the downstream end of the substrate B2 is carried to the mounting position Pm2 ("YES" in step S101), the presence of an unmounted point of the substrate B2 is determined (step S102). The component Wp is not mounted on the downstream half of the plurality of mounting target points Bp of the substrate B2 ("YES" in step S102), so the mounting position Pm2 is the most downstream mounting position Pm in step S103. It is judged. Since the mounting position Pm2 is the most downstream mounting position Pm ("YES" in step S103), the process proceeds to step S106. Then, in step S106, the control unit 100 determines to distribute the component mounting on the unmounted point of the substrate B2 to the main mounting position Pm2. As a result, as shown in the column of operation A105 in FIG. 4, the substrate B2 is carried to the mounting position Pm2, and components to the normal distribution point (downstream half) of the mounting position Pm2 among all mounting target points Bp of the substrate B2 The mounting is distributed to the mounting position Pm2.
 また、4番目の基板B4の下流端が実装位置Pm1に搬入されると(ステップS101で「YES」)、ステップS102で基板B4に未実装点が存在する(YES)と判断され、さらにステップS103で本実装位置Pm1が最下流の実装位置Pmでない(NO)と判断され、ステップS104に進む。下流の実装位置Pm2は先の基板B2に部品実装を実行予定であるため、ステップS104では、実装位置Pm2では基板B4の部品実装を実装できない(NO)と判断され、ステップS106に進む。そして、ステップS106では、制御部100は、基板B4の部品実装を実装位置Pm1に分配すると決定する。これによって、図4の動作A105の欄に示すように、基板B4が実装位置Pm1に搬入され、基板B4の全実装対象点Bpのうち実装位置Pm1の通常分配点(上流側半分)への部品実装が実装位置Pm1に分配される。 When the downstream end of the fourth substrate B4 is carried to the mounting position Pm1 ("YES" in step S101), it is determined in step S102 that there is an unmounted point on the substrate B4 (YES), and step S103. Then, it is determined that the present mounting position Pm1 is not the most downstream mounting position Pm (NO), and the process proceeds to step S104. Since the downstream mounting position Pm2 is to perform component mounting on the previous substrate B2, in step S104, it is determined that the component mounting of the substrate B4 can not be mounted at the mounting position Pm2 (NO), and the process proceeds to step S106. Then, in step S106, the control unit 100 determines to distribute the component mounting of the substrate B4 to the mounting position Pm1. As a result, as shown in the column of operation A105 in FIG. 4, the board B4 is carried to the mounting position Pm1, and a component to the normal distribution point (upstream half) of the mounting position Pm1 among all mounting target points Bp of the board B4 The mounting is distributed to the mounting position Pm1.
 そして、実装位置Pm2では、実装位置Pm2への通常分配点への部品実装が2番目の基板B2に対して開始され、実装位置Pm1では、実装位置Pm1への通常分配点への部品実装が4番目の基板B4に対して開始される。図4の動作A106の欄に示すように、実装位置Pm2で分配された部品実装が基板B2に対して完了すると(ステップS201で「YES」)、基板B2に未実装点が存在するかが判断される(ステップS202)。基板B2の全実装対象点Bpに対して部品Wpが実装されているため(ステップS202で「NO」)、図4の動作A107の欄に示すように、基板B2が実装位置Pm2から下流へ搬出され、基板B3の下流への搬送が開始される(ステップS205)。 Then, at the mounting position Pm2, component mounting to the normal distribution point to the mounting position Pm2 is started for the second board B2, and at the mounting position Pm1, component mounting to the normal distribution point to the mounting position Pm1 is 4 The second substrate B4 is started. As shown in the column of operation A106 in FIG. 4, when the component mounting distributed at the mounting position Pm2 is completed on the substrate B2 (“YES” in step S201), it is determined whether there is an unmounted point on the substrate B2 (Step S202). Since the component Wp is mounted on all mounting target points Bp of the substrate B2 ("NO" in step S202), the substrate B2 is unloaded downstream from the mounting position Pm2, as shown in the column of operation A107 in FIG. The transport of the substrate B3 to the downstream is started (step S205).
 図4の動作A106の欄に示すように、実装位置Pm1で分配された部品実装が基板B4に対して完了すると(ステップS201で「YES」)、基板B4に未実装点が存在するかが判断される(ステップS202)。基板B4の複数の実装対象点Bpのうち下流側半分に部品Wpが実装されていないため(ステップS202で「YES」)、実装位置Pm1の上流側、すなわち待機コンベア21に基板Bが存在するかが判断される(ステップS203)。待機コンベア21には基板Bが存在しないため(ステップS203で「NO」)、ステップS206に進む。ステップS206では、制御部100は、基板B4の部品実装を実装位置Pm1に分配すると決定する。これによって、図4の動作A107の欄に示すように、基板B4は実装位置Pm1に留まり、基板B4の全実装対象点Bpのうち実装位置Pm2の通常分配点(下流側半分)への部品実装が実装位置Pm1に分配される。 As shown in the column of operation A106 in FIG. 4, when the component mounting distributed at the mounting position Pm1 is completed on the substrate B4 ("YES" in step S201), it is determined whether there is an unmounted point on the substrate B4. (Step S202). Since the component Wp is not mounted on the downstream half of the plurality of mounting target points Bp of the substrate B4 (“YES” in step S202), does the substrate B exist on the upstream side of the mounting position Pm1, ie, the standby conveyor 21? Is determined (step S203). Since the substrate B does not exist on the standby conveyor 21 ("NO" in step S203), the process proceeds to step S206. In step S206, the control unit 100 determines to distribute the component mounting of the substrate B4 to the mounting position Pm1. As a result, as shown in the column of operation A107 in FIG. 4, the substrate B4 remains at the mounting position Pm1 and component mounting to the normal distribution point (downstream half) of the mounting position Pm2 among all mounting target points Bp of the substrate B4. Are distributed to the mounting position Pm1.
 基板B3の下流端が実装位置Pm2に搬入されると(ステップS101で「YES」)、基板B3の未実装点の存在が判断される(ステップS102)。基板B3の複数の実装対象点Bpのうち下流側半分には部品Wpが実装されていないため(ステップS102で「YES」)、ステップS103で、本実装位置Pm3が最下流の実装位置Pmであるかが判断される。実装位置Pm2は最下流の実装位置Pmであるため(ステップS103で「YES」)、ステップS106へ進む。そして、ステップS106では、制御部100は、基板B3の未実装点への部品実装を本実装位置Pm2に分配すると決定する。これによって、図4の動作A107に示すように、基板B3が実装位置Pm2に搬入され、基板B3の全実装対象点Bpのうち実装位置Pm2の通常分配点(下流側半分)への部品実装が実装位置Pm2に分配される。 When the downstream end of the substrate B3 is carried to the mounting position Pm2 ("YES" in step S101), the presence of an unmounted point of the substrate B3 is determined (step S102). The component Wp is not mounted on the downstream half of the plurality of mounting target points Bp of the substrate B3 ("YES" in step S102), so the mounting position Pm3 is the most downstream mounting position Pm in step S103. It is judged. Since the mounting position Pm2 is the most downstream mounting position Pm ("YES" in step S103), the process proceeds to step S106. Then, in step S106, the control unit 100 determines that the component mounting on the unmounted point of the substrate B3 is to be distributed to the main mounting position Pm2. As a result, as shown in operation A107 of FIG. 4, the board B3 is carried to the mounting position Pm2, and component mounting to the normal distribution point (downstream half) of the mounting position Pm2 among all mounting target points Bp of the board B3 is performed. It is distributed to the mounting position Pm2.
 そして、実装位置Pm2では、実装位置Pm2への通常分配点への部品実装が3番目の基板B3に対して開始され、実装位置Pm1では、実装位置Pm2への通常分配点への部品実装が4番目の基板B4に対して開始される。図4の動作A108の欄に示すように、実装位置Pm2で分配された部品実装が基板B3に対して完了すると(ステップS201で「YES」)、基板B3に未実装点が存在するかが判断される(ステップS202)。基板B3の全実装対象点Bpに対して部品Wpが実装されているため(ステップS202で「NO」)、基板B3が実装位置Pm2から下流へ搬出される(ステップS205)。 Then, at the mounting position Pm2, component mounting to the normal distribution point to the mounting position Pm2 is started for the third board B3, and at the mounting position Pm1, component mounting to the normal distribution point to the mounting position Pm2 is 4 The second substrate B4 is started. As shown in the column of operation A108 in FIG. 4, when the component mounting distributed at the mounting position Pm2 is completed on the substrate B3 ("YES" in step S201), it is determined whether there is an unmounted point on the substrate B3. (Step S202). Since the component Wp is mounted on all mounting target points Bp of the substrate B3 ("NO" in step S202), the substrate B3 is unloaded downstream from the mounting position Pm2 (step S205).
 図4の動作A108の欄に示すように、実装位置Pm1で分配された部品実装が基板B4に対して完了すると(ステップS201で「YES」)、基板B4に未実装点が存在するかが判断される(ステップS202)。基板B4の全実装対象点Bpに対して部品Wpが実装されているため(ステップS202で「NO」)、基板B4が実装位置Pm1から下流へ搬出される(ステップS205)。さらに、基板B4の下流端が実装位置Pm2に搬入されると(ステップS101で「YES」)、基板B4に未実装点が存在するかが判断される(ステップS102)。基板B4の全実装対象点Bpに対して部品Wpが実装されているため(ステップS102で「NO」)、ステップS107で基板B4が実装位置Pm1から下流へ搬出される。 As shown in the column of operation A108 in FIG. 4, when the component mounting distributed at the mounting position Pm1 is completed on the substrate B4 ("YES" in step S201), it is determined whether there is an unmounted point on the substrate B4.

Furthermore, when the downstream end of the substrate B4 is carried to the mounting position Pm2 ("YES" in step S101), it is determined whether there is an unmounted point on the substrate B4 (step S102). Since the component Wp is mounted on all mounting target points Bp of the substrate B4 ("NO" in step S102), the substrate B4 is unloaded downstream from the mounting position Pm1 in step S107.
 以上のように構成された実施形態では、実装位置Pmの個数Mは「2」であり、基板Bの枚数Lは「4」である。つまり、一の基板Bに設けられた複数の実装対象点Bpに対する部品実装が2個の実装位置Pm1、Pm2の間で分配される。そして、当該一の基板Bを基板搬送方向Xに搬送しつつ2個の実装位置Pm1、Pm2のうち部品実装を分配した実装位置Pmに停止させて、実装位置Pmで停止する当該一の基板Bに対して実装位置Pmに分配された部品実装が実行される。この際、4枚の基板B1~B4のうち基板搬送方向Xへの搬送順序NがM未満の基板B1に対しては初期実装モード(動作A101~A104における基板B1に対する動作)で部品実装が実行され、搬送順序NがM以上であって(L-M+2)番未満の基板B3に対しては通常実装モード(動作A103~A108における基板B3に対する動作)で部品実装が実行される。初期実装モードでは、搬送順序1の基板B1に関して、2個の実装位置Pm1、Pm2のうち基板搬送方向Xの上流側から数えて1番目の実装位置Pm1よりも下流側の実装位置Pm2に基板B1への部品実装が選択的に分配される。したがって、基板B1は1番目の実装位置Pm1を通過して、1番目の実装位置Pm1よりも下流側の実装位置Pm2で基板B1の複数の実装対象点Bpへの部品実装が実行される。一方、通常実装モードでは、2個の実装位置Pm1、Pm2のそれぞれに基板B3への部品実装が分配され、基板B3は2個の実装位置Pm1、Pm2に順番に停止して、2個の実装位置Pm1、Pm2のそれぞれで順番に基板B3の複数の実装対象点Bpへの部品実装が実行される。 In the embodiment configured as described above, the number M of the mounting positions Pm is “2”, and the number L of the substrates B is “4”. That is, component mounting with respect to a plurality of mounting target points Bp provided on one substrate B is distributed between two mounting positions Pm1 and Pm2. Then, the first substrate B is stopped at the mounting position Pm at which the component mounting is distributed among the two mounting positions Pm1 and Pm2 while being transported in the substrate transfer direction X, and the first substrate B is stopped at the mounting position Pm. The component mounting distributed to the mounting position Pm is performed. At this time, component mounting is performed in the initial mounting mode (operation with respect to the substrate B1 in the operations A101 to A104) on the substrate B1 having a conveyance order N in the substrate conveyance direction X of less than M among the four substrates B1 to B4. The component mounting is performed in the normal mounting mode (the operation on the substrate B3 in the operations A103 to A108) on the substrate B3 having the transport order N of M or more and less than (L−M + 2). In the initial mounting mode, the board B1 at the mounting position Pm2 on the downstream side of the first mounting position Pm1 among the two mounting positions Pm1 and Pm2 with respect to the board B1 in the conveyance order 1 is counted from the upstream side Component mounting on is selectively distributed. Therefore, the substrate B1 passes the first mounting position Pm1, and component mounting to a plurality of mounting target points Bp of the substrate B1 is performed at the mounting position Pm2 downstream of the first mounting position Pm1. On the other hand, in the normal mounting mode, component mounting on the substrate B3 is distributed to each of the two mounting positions Pm1 and Pm2, and the substrate B3 is stopped at the two mounting positions Pm1 and Pm2 in order, and the two mountings are performed. Component mounting to a plurality of mounting target points Bp of the substrate B3 is sequentially performed at each of the positions Pm1 and Pm2.
 したがって、4枚の基板のうち搬送順序が最初の2枚の基板については、次のようにして部品実装が実行される。つまり、1番目の基板B1は、初期実装モードによって、基板搬送方向Xの上流側から数えて2番目の実装位置Pm2に搬送され、2番目の基板B2は、通常実装モードによって、基板搬送方向Xの上流側から数えて1番目の実装位置Pm1に搬送される。こうして、2個の実装位置Pm1、Pm2のそれぞれに基板B2、B1を搬送して、各実装位置Pm1、Pm2で基板B2、B1への部品実装を開始することができる。これによって、部品実装システム1の稼働率の低下を抑制することが可能となっている。 Therefore, component mounting is performed on the first two substrates out of the four substrates in the following manner. That is, the first substrate B1 is transported to the second mounting position Pm2 from the upstream side in the substrate transport direction X in the initial mounting mode, and the second substrate B2 is in the substrate transport direction X in the normal mounting mode. From the upstream side to the first mounting position Pm1. Thus, the substrates B2 and B1 can be transported to the two mounting positions Pm1 and Pm2, respectively, and component mounting on the substrates B2 and B1 can be started at the mounting positions Pm1 and Pm2. By this, it is possible to suppress a decrease in the operation rate of the component mounting system 1.
 また、搬送部2は、基板搬送方向Xに隣り合う実装位置Pm1、Pm2の間に配置された待機位置Pwをさらに有する。そして、基板搬送方向Xにおいて、2個の実装位置Pm1、Pm2のうち、最下流の実装位置Pm2以外の実装位置Pm1は、下流側で隣り合う実装位置Pm2で部品実装が実行する場合には、分配された部品実装が完了した基板Bを下流側の待機位置Pwに搬出して、分配された部品実装が未完の基板Bを基板搬送方向Xの上流側から搬入する(動作A102~A103の基板B2、B3等)。かかる構成では、最下流の実装位置Pm2以外の実装位置Pm1では、分配された部品実装が完了した基板Bを速やかに待機位置Pwに搬出され、部品実装が未完の次の基板Bが基板搬送方向Xの上流側から搬入される。その結果、部品実装システム1の稼働率の低下をより効果的に抑制することが可能となっている。 The transport unit 2 further includes a standby position Pw disposed between the mounting positions Pm1 and Pm2 adjacent to each other in the substrate transport direction X. Then, among the two mounting positions Pm1 and Pm2 in the substrate transport direction X, the mounting position Pm1 other than the mounting position Pm2 at the most downstream is the part mounting at the mounting position Pm2 adjacent on the downstream side. The distributed component mounting completed substrate B is carried out to the standby position Pw on the downstream side, and the substrate B for which the distributed component mounting is incomplete is carried in from the upstream side in the substrate transport direction X (substrates of operations A102 to A103 B2, B3 etc.). In such a configuration, at the mounting position Pm1 other than the most downstream mounting position Pm2, the distributed substrate mounting completed components B are promptly carried out to the standby position Pw, and the next substrate B for which component mounting is not completed is in the substrate conveyance direction It is carried in from the upstream side of X. As a result, it is possible to more effectively suppress the decrease in the operation rate of the component mounting system 1.
 また、通常実装モードでは、実装位置Pm1、Pm2のそれぞれで部品Wpが実装される実装対象点Bpの個数の差が1個以下となるように(上記の実施形態では、個数の差はゼロである)、2個の実装位置Pm1、Pm2のそれぞれに基板Bへの部品実装が分配される。一方、初期実装モードでは、搬送順序1の基板B1に関して、基板搬送方向Xの上流側から数えて2番目の実装位置Pm2には、通常実装モードで基板搬送方向Xの上流側から数えて1番目から2番目までの実装位置Pm1、Pm2に分配される部品実装が分配される。かかる構成では、仮に搬送順序NがM未満の基板B1に対して通常実装モードを実行した場合に、基板搬送方向Xの上流側から数えて1番目から2番目までの実装位置Pm1、Pm2に分配される部品実装が、初期実装モードにおいて2番目の実装位置Pm2に分配される。つまり、初期実装モードでは、搬送順序1の基板B1に関して、2番目の実装位置Pm2より上流側の実装位置Pm1での部品実装が省略されるものの、この部品実装を2番目の実装位置Pm2で確実に実行することが可能となっている。 Further, in the normal mounting mode, the difference in the number of mounting target points Bp on which the component Wp is mounted at each of the mounting positions Pm1 and Pm2 is 1 or less (in the above embodiment, the number difference is zero). Component mounting on the substrate B is distributed to each of the two mounting positions Pm1 and Pm2). On the other hand, in the initial mounting mode, the second mounting position Pm2 from the upstream side in the substrate conveyance direction X with respect to the substrate B1 in the conveyance order 1 is the first from the upstream side in the substrate conveyance direction X in the normal mounting mode. The component mountings distributed to the second to the second mounting positions Pm1 and Pm2 are distributed. In this configuration, if the normal mounting mode is executed for a substrate B1 having a transport order N less than M, distribution to the first to second mounting positions Pm1 and Pm2 counted from the upstream side in the substrate transport direction X is performed. Component mounting is distributed to the second mounting position Pm2 in the initial mounting mode. That is, in the initial mounting mode, component mounting at the mounting position Pm1 on the upstream side of the second mounting position Pm2 is omitted for the substrate B1 in transport order 1, but this component mounting is assured at the second mounting position Pm2. It is possible to carry out.
 また、通常実装モードにおいて、実装位置Pm1、Pm2のそれぞれで部品Wpが実装される実装対象点Bpの個数の差を1個以下とすることで、各実装位置Pm1、Pm2での実装時間を均等化できる。すなわち、各実装位置Pm1、Pm2での実装対象点Bpの個数がおおよそ均等であれば、各実装位置Pm1、Pm2からの基板Bの搬送を略同時に実行できる。また、各実装位置Pm1、Pm2の実装時間自体が均等化されるように、各実装位置Pm1、Pm2での実装対象点Bpの個数を決めても良い。この場合、各実装位置Pm1、Pm2での実装時間を完全に等しくできないにしても、各実装位置Pm1、Pm2での実装時間の差を抑えるように、各実装位置Pm1、Pm2での実装対象点Bpの個数を決めても良い。 Also, by setting the difference in the number of mounting target points Bp on which the component Wp is mounted at each of the mounting positions Pm1 and Pm2 in the normal mounting mode to one or less, the mounting time at each mounting position Pm1 and Pm2 is equalized. Can be That is, if the numbers of mounting target points Bp at the mounting positions Pm1 and Pm2 are approximately equal, conveyance of the substrate B from the mounting positions Pm1 and Pm2 can be substantially simultaneously performed. In addition, the number of mounting target points Bp at each mounting position Pm1 and Pm2 may be determined so that the mounting time itself of each mounting position Pm1 and Pm2 is equalized. In this case, even if the mounting times at the mounting positions Pm1 and Pm2 can not be completely equalized, the mounting target points at the mounting positions Pm1 and Pm2 can be reduced so as to suppress the difference between the mounting times at the mounting positions Pm1 and Pm2. You may decide the number of Bp.
 また、制御部100は、4枚の基板B1~B4のうち搬送順序Nが4番以上の基板B4に対しては終期実装モード(動作A105~A108における基板B4に対する動作)で部品実装を実行する。この終期実装モードでは、搬送順序4の基板B4に関して、2個の実装位置Pm1、Pm2のうち基板搬送方向Xの上流側から数えて1番目の実装位置Pm1に基板B4への部品実装が選択的に分配され、1番目の実装位置Pm1で基板B4の複数の実装対象点Bpへの部品実装が実行される。かかる構成では、4枚の基板B1~B4のうち搬送順序Nが(L-M+2)番以上の基板B4に対しては、2個の実装位置Pm1、Pm2のうち基板搬送方向Xの上流側から数えて1番目の実装位置Pm1に基板B4への部品実装が選択的に分配され、1番目の実装位置Pm1で基板B4の複数の実装対象点Bpへの部品実装が実行される。したがって、基板搬送方向Xにおいて、1番目より下流側の実装位置Pm2で部品実装を実行中であっても、1番目の実装位置Pm1を稼動させて、搬送順序Nが(L-M+2)番以上の基板B4に対して部品実装を効率的に実行できる。その結果、部品実装システム1の稼働率の低下をより効果的に抑制することが可能となっている。 In addition, the control unit 100 performs component mounting in the final mounting mode (operation on the substrate B4 in operations A105 to A108) on the substrate B4 having a conveyance order N of 4 or more among the four substrates B1 to B4. . In this final mounting mode, with regard to the substrate B4 in the conveyance order 4, component mounting on the substrate B4 is selective at the first mounting position Pm1 of the two mounting positions Pm1 and Pm2 counting from the upstream side in the substrate conveyance direction X. , And component mounting to a plurality of mounting target points Bp of the substrate B4 is performed at the first mounting position Pm1. In this configuration, for the substrate B4 having a transport order N of (L−M + 2) or more among the four substrates B1 to B4, the two mounting positions Pm1 and Pm2 from the upstream side in the substrate transport direction X Component mounting on the substrate B4 is selectively distributed to the first mounting position Pm1 and component mounting on a plurality of mounting target points Bp of the substrate B4 is executed at the first mounting position Pm1. Therefore, even while component mounting is being performed at the mounting position Pm2 downstream of the first in the substrate transfer direction X, the first mounting position Pm1 is operated, and the transfer order N is (L−M + 2) or more Component mounting can be efficiently performed on the substrate B4 of As a result, it is possible to more effectively suppress the decrease in the operation rate of the component mounting system 1.
 また、終期実装モードでは、搬送順序4の基板B4に関して、基板搬送方向Xの上流側から数えて1番目の実装位置Pm1には、通常実装モードで基板搬送方向Xの上流側から数えて1番目から2番目までの実装位置Pm1、Pm2に分配される部品実装が分配される。かかる構成では、仮に搬送順序Nが(L-M+2)番以上の基板B4に対して通常実装モードを実行した場合に、基板搬送方向Xの上流側から数えて1番目から2番目までの実装位置Pm1、Pm2に分配される部品実装が、終期実装モードにおいて1番目の実装位置Pm1に分配される。つまり、終期実装モードでは、搬送順序4の基板B4に関して、1番目の実装位置Pm1より下流側の実装位置Pm2での部品実装が省略されるものの、この部品実装を1番目の実装位置Pm1で確実に実行することが可能となっている。 In the final mounting mode, the first mounting position Pm1 counted from the upstream side in the substrate conveyance direction X with respect to the substrate B4 in the conveyance order 4 is counted from the upstream side in the substrate conveyance direction X in the normal mounting mode. The component mountings distributed to the second to the second mounting positions Pm1 and Pm2 are distributed. In this configuration, if the normal mounting mode is executed for the substrate B4 having the transport order N equal to or greater than (L−M + 2), the first to the second mounting positions counted from the upstream side in the substrate transport direction X The component mounting distributed to Pm1 and Pm2 is distributed to the first mounting position Pm1 in the final mounting mode. That is, in the final mounting mode, with regard to the substrate B4 in the transport order 4, component mounting at the mounting position Pm2 downstream of the first mounting position Pm1 is omitted, but this component mounting is assured at the first mounting position Pm1 It is possible to carry out.
 図5および図6は図2および図3のフローチャートに従って実行される動作の第2例を模式的に示す図である。図5および図6では、8枚(すなわち、L=8)の基板Bを基板搬送方向Xに順番に搬送しつつ、各基板Bに部品実装を実行する例が示されている。また、図5および図6では、L枚の基板Bの搬送順序N(N=1~8)が符号Bに付されている。 5 and 6 schematically show a second example of the operation performed in accordance with the flowcharts of FIGS. 2 and 3. FIGS. 5 and 6 show an example in which component mounting is performed on each substrate B while sequentially transporting eight substrates B (that is, L = 8) in the substrate transport direction X. Further, in FIG. 5 and FIG. 6, the transport order N (N = 1 to 8) of the L substrates B is given the reference numeral B.
 図5および図6に示すように、搬送部2では、実装コンベア24と搬出コンベア25(図1)との間に、待機コンベア26と実装コンベア27とが基板搬送方向Xにこの順で並べて設けられており、待機コンベア26は待機位置Pw2で基板Bを停止・固定させ、実装コンベア27は実装位置Pm3で基板Bを停止・固定させる。つまり、搬送部2では、M個の実装位置Pm1、Pm2、Pm3が基板搬送方向Xに並んで設けられており、基板搬送方向Xに隣り合う実装位置Pm1、Pm2の間に待機位置Pw1が配置され、基板搬送方向Xに隣り合う実装位置Pm2、Pm3の間に待機位置Pw2が配置されている。ここで、図5および図6の例ではM=3であり、3個の実装位置Pm1、Pm2、Pm3に一対一で対応して3個の実装部4が設けられており、各実装部4は対応する実装位置Pmで停止する基板Bに対して部品実装を実行する。なお、以下では、実装位置Pm1、Pm2、Pm3を区別しない場合には、実装位置Pmと称し、待機位置Pw1、Pw2を区別しない場合には、待機位置Pwと称する。 As shown in FIGS. 5 and 6, in the transport unit 2, the standby conveyor 26 and the mounting conveyor 27 are provided in this order in the substrate transport direction X between the mounting conveyor 24 and the unloading conveyor 25 (FIG. 1). The standby conveyor 26 stops and fixes the substrate B at the standby position Pw2, and the mounting conveyor 27 stops and fixes the substrate B at the mounting position Pm3. That is, in the transport unit 2, the M mounting positions Pm1, Pm2, and Pm3 are provided side by side in the substrate transport direction X, and the standby position Pw1 is disposed between the mount positions Pm1 and Pm2 adjacent in the substrate transport direction X The standby position Pw2 is disposed between the mounting positions Pm2 and Pm3 adjacent to each other in the substrate transfer direction X. Here, in the example of FIGS. 5 and 6, M = 3, and three mounting portions 4 are provided corresponding to the three mounting positions Pm1, Pm2, and Pm3 in a one-to-one manner. Executes component mounting on the substrate B stopped at the corresponding mounting position Pm. Hereinafter, when the mounting positions Pm1, Pm2, and Pm3 are not distinguished, they are referred to as mounting positions Pm, and when the standby positions Pw1 and Pw2 are not distinguished from each other, they are referred to as waiting positions Pw.
 第2例においても、制御部100は、L枚の基板Bを順番に搬送部2により搬送しつつ各基板Bに部品実装を実行するにあたっては、基板Bの搬送順序Nに応じて実装位置Pm1、Pm2、Pm3への部品実装の分配を動的に変更する。この際、実装位置Pmの個数の違いに応じて、通常実装モードで実装位置Pm1、Pm2、Pm3のそれぞれに分配される実装対象点Bpが第1例と異なる。つまり、基板Bの複数の実装対象点Bpのうち、実装位置Pm1では上流側の3分の1の実装対象点Bp(通常分配点)に対して部品Wpが実装され、実装位置Pm2では中央の3分の1の実装対象点Bp(通常分配点)に対して部品Wpが実装され、実装位置Pm3では下流側の3分の1の実装対象点Bp(通常分配点)に対して部品Wpが実装される。 Also in the second example, when the control unit 100 performs component mounting on each substrate B while sequentially conveying L sheets of the substrate B by the conveyance unit 2, the mounting position Pm 1 according to the conveyance order N of the substrate B , Pm2, Pm3 dynamically change the distribution of component mounting. At this time, the mounting target points Bp distributed to the mounting positions Pm1, Pm2, and Pm3 in the normal mounting mode differ from the first example according to the difference in the number of the mounting positions Pm. That is, of the plurality of mounting target points Bp of the substrate B, the component Wp is mounted at the mounting position Pm1 on the upstream one-third mounting target point Bp (normal distribution point), and the mounting position Pm2 is central at the center The component Wp is mounted to the mounting target point Bp (normal distribution point) of 1/3, and the mounting position Pm3 is the part Wp to the mounting target point Bp (normal distribution point) on the downstream side. Implemented.
 そして、制御部100は、実装位置Pm1、Pm2、Pm3のそれぞれについて図2および図3のフローチャートに示す搬入時・実装完了時判断処理を実行することで、図5および図6の動作を実行する。なお、図2および図3のフローチャートに基づく判断の詳細は上記の第1例と同様であるので、その説明は適宜省略する。 Then, the control unit 100 executes the operations of FIG. 5 and FIG. 6 by executing the carrying-in / mounting completion determination process shown in the flowcharts of FIGS. . The details of the determination based on the flowcharts of FIGS. 2 and 3 are the same as those of the first example described above, and thus the description thereof will be omitted as appropriate.
 図5の動作A201の欄に示すように、1番目の基板B1を基板搬送方向Xに搬送しつつ、基板B1に対して実装位置Pm1、Pm2、Pm3のそれぞれで搬入時判断処理が実行された結果、基板B1は、実装位置Pm1、Pm2を通過して実装位置Pm3に搬入され、基板B1への部品実装が実装位置Pm3に分配される。具体的には、基板B1が停止せずに通過した実装位置Pm1、Pm2への通常分配点と、基板B1の搬入先である実装位置Pm3への通常分配点とに対する部品実装が、実装位置Pm3に分配される。これによって、基板B1の全実装対象点Bpへの部品実装が実装位置Pm3に分配される。 As shown in the column of operation A201 of FIG. 5, while carrying the first substrate B1 in the substrate transfer direction X, the loading determination process is executed at each of the mounting positions Pm1, Pm2, and Pm3 with respect to the substrate B1. As a result, the substrate B1 passes the mounting positions Pm1 and Pm2 and is carried to the mounting position Pm3, and the component mounting on the substrate B1 is distributed to the mounting position Pm3. Specifically, the component mounting at the normal distribution point to the mounting positions Pm1 and Pm2 through which the substrate B1 passes without stopping and the normal distribution point to the mounting position Pm3 to which the substrate B1 is carried is the mounting position Pm3. Distributed to As a result, component mounting on all mounting target points Bp of the substrate B1 is distributed to the mounting position Pm3.
 また、2番目の基板B2を基板搬送方向Xに搬送しつつ、基板B2に対して実装位置Pm1、Pm2のそれぞれで搬入時判断処理が実行された結果、基板B2は、実装位置Pm1を通過して実装位置Pm2に搬入され、基板B2への部品実装が実装位置Pm2に分配される。具体的には、基板B2が停止せずに通過した実装位置Pm1への通常分配点と、基板B2の搬入先である実装位置Pm2への通常分配点とに対する部品実装が、実装位置Pm2に分配される。これによって、基板B2の上流側の3分の2の実装対象点Bpへの部品実装が実装位置Pm2に分配される。 In addition, as a result of carrying out determination processing at the loading position Pm1 and Pm2 with respect to the substrate B2 while transporting the second substrate B2 in the substrate transport direction X, the substrate B2 passes the mounting position Pm1. Is carried into the mounting position Pm2, and component mounting on the substrate B2 is distributed to the mounting position Pm2. Specifically, component mounting for the normal distribution point to the mounting position Pm1 through which the substrate B2 passes without stopping and the normal distribution point to the mounting position Pm2 to which the substrate B2 is carried is distributed to the mounting position Pm2 Be done. As a result, component mounting on the two thirds of the mounting target points Bp on the upstream side of the substrate B2 is distributed to the mounting position Pm2.
 さらに、3番目の基板B3を基板搬送方向Xに搬送しつつ、基板B3に対して実装位置Pm1で搬入時判断処理が実行された結果、基板B3は実装位置Pm1に搬入され、基板B3への部品実装が実装位置Pm1に分配される。具体的には、実装位置Pm1の通常分配点に対する部品実装が、実装位置Pm1に分配される。これによって、基板B3の上流側の3分の1の実装対象点Bp(通常分配点)への部品実装が実装位置Pm1に分配される。 Furthermore, as the third substrate B3 is transported in the substrate transport direction X, the loading determination process is performed on the substrate B3 at the mounting position Pm1. As a result, the substrate B3 is transported to the mounting position Pm1 and is transferred to the substrate B3. The component mounting is distributed to the mounting position Pm1. Specifically, component mounting for the normal distribution point of the mounting position Pm1 is distributed to the mounting position Pm1. As a result, component mounting on the upstream one-third mounting target point Bp (normal distribution point) on the upstream side of the substrate B3 is distributed to the mounting position Pm1.
 そして、実装位置Pm3では、実装位置Pm1、Pm2、Pm3への通常分配点への部品実装が1番目の基板B1に対して開始され、実装位置Pm2では、実装位置Pm1、Pm2への通常分配点への部品実装が2番目の基板B2に対して開始され、実装位置Pm1では、実装位置Pm1への通常分配点への部品実装が1番目の基板B3に対して開始される。図5の動作A202の欄に示すように、実装位置Pm1で分配された部品実装が基板B3に対して完了すると、実装位置Pm1で実装完了時判断処理が実行される。その結果、図5の動作A203の欄に示すように、基板B3が実装位置Pm1から待機位置Pw1に搬出される。これと並行して、4番目の基板B4の下流への搬送が開始されて、基板B4の下流端が実装位置Pm1に搬入されると、実装位置Pm1で搬入時判断処理が実行される。その結果、図5の動作A203の欄に示すように、基板B4が実装位置Pm1に搬入され、基板B4への部品実装が実装位置Pm1に分配される。これによって、実装位置Pm1には、基板B4の複数の実装対象点Bpのうち実装位置Pm1への通常分配点への部品実装が分配され、実装位置Pm1ではこの部品実装が基板B4に対して開始される。 Then, at the mounting position Pm3, component mounting to the normal distribution points to the mounting positions Pm1, Pm2 and Pm3 is started for the first board B1, and at the mounting position Pm2, normal distribution points to the mounting positions Pm1 and Pm2 Component mounting to the second substrate B2 starts, and at the mounting position Pm1, component mounting to the normal distribution point to the mounting position Pm1 starts to the first substrate B3. As shown in the column of operation A202 of FIG. 5, when the component mounting distributed at the mounting position Pm1 is completed on the substrate B3, the mounting completion determination process is executed at the mounting position Pm1. As a result, as shown in the column of operation A203 of FIG. 5, the substrate B3 is unloaded from the mounting position Pm1 to the standby position Pw1. At the same time, the conveyance of the fourth substrate B4 to the downstream is started, and when the downstream end of the substrate B4 is carried to the mounting position Pm1, the carrying-in determination process is executed at the mounting position Pm1. As a result, as shown in the column of operation A203 in FIG. 5, the substrate B4 is carried to the mounting position Pm1, and the component mounting on the substrate B4 is distributed to the mounting position Pm1. As a result, the component mounting to the normal distribution point to the mounting position Pm1 among the plurality of mounting target points Bp of the substrate B4 is distributed to the mounting position Pm1, and the component mounting starts to the substrate B4 at the mounting position Pm1. Be done.
 図5の動作A204の欄に示すように、実装位置Pm2で分配された部品実装が基板B2に対して完了すると、実装位置Pm2で実装完了時判断処理が実行される。その結果、図5の動作A205の欄に示すように、基板B2が実装位置Pm2から待機位置Pw2に搬出される。これと並行して、基板B3の下流への搬送が開始され、基板B3の下流端が実装位置Pm2に搬入されると、実装位置Pm2で搬入時判断処理が実行される。その結果、図5の動作A205の欄に示すように、基板B3が実装位置Pm2に搬入され、基板B3への部品実装が実装位置Pm2に分配される。これによって、実装位置Pm2には、基板B3の複数の実装対象点Bpのうち実装位置Pm2への通常分配点への部品実装が分配され、実装位置Pm2ではこの部品実装が基板B3に対して開始される。 As shown in the column of operation A204 in FIG. 5, when the component mounting distributed at the mounting position Pm2 is completed on the substrate B2, the mounting completion determination process is executed at the mounting position Pm2. As a result, as shown in the column of operation A205 in FIG. 5, the substrate B2 is unloaded from the mounting position Pm2 to the standby position Pw2. At the same time, transport of the substrate B3 to the downstream is started, and when the downstream end of the substrate B3 is carried into the mounting position Pm2, the carrying-in determination process is executed at the mounting position Pm2. As a result, as shown in the column of operation A205 of FIG. 5, the substrate B3 is carried to the mounting position Pm2, and the component mounting on the substrate B3 is distributed to the mounting position Pm2. As a result, the component mounting to the normal distribution point to the mounting position Pm2 among the plurality of mounting target points Bp of the substrate B3 is distributed to the mounting position Pm2, and the component mounting starts to the substrate B3 at the mounting position Pm2. Be done.
 図5の動作A204の欄に示すように、実装位置Pm1で分配された部品実装が基板B4に対して完了すると、実装位置Pm1で実装完了時判断処理が実行される。その結果、図5の動作A205の欄に示すように、基板B4が実装位置Pm1から待機位置Pw1に搬出される。これと並行して、5番目の基板B5の下流への搬送が開始され、基板B5の下流端が実装位置Pm1に搬入されると、実装位置Pm1で搬入時判断処理が実行される。その結果、図5の動作A205の欄に示すように、基板B5が実装位置Pm1に搬入され、基板B5への部品実装が実装位置Pm1に分配される。これによって、実装位置Pm1には、基板B5の複数の実装対象点Bpのうち実装位置Pm1への通常分配点への部品実装が分配され、実装位置Pm1ではこの部品実装が基板B5に対して開始される。 As shown in the column of operation A204 in FIG. 5, when the component mounting distributed at the mounting position Pm1 is completed on the board B4, the mounting completion determination process is executed at the mounting position Pm1. As a result, as shown in the column of operation A205 of FIG. 5, the substrate B4 is unloaded from the mounting position Pm1 to the standby position Pw1.

Then, one of the three mounting positions Pm1, Pm2, and Pm3 is stopped at the mounting position Pm at which the component mounting is distributed, and is stopped at the mounting position Pm while conveying the one substrate B in the substrate conveyance direction X Component mounting distributed to the mounting position Pm with respect to the substrate B is performed. At this time, among the eight substrates B1 to B8, the substrates B1 and B2 having a transport order N in the substrate transport direction X less than M in the initial mounting mode (operations on the substrates B1 and B2 in operations A201 to A208) Component mounting is performed, and components mounting is performed in the normal mounting mode (operations on substrates B3 to B6 in operations A201 to A216) for substrates B3 to B6 having a transport order N of M or more and less than (L−M + 2) Is executed. In the initial mounting mode, of the three mounting positions Pm1, Pm2, and Pm3 with respect to the substrate B1 having the conveyance order 1, the mounting position Pm3 on the downstream side of the second mounting position Pm2 is counted from the upstream side of the substrate conveyance direction X. Component mounting on the substrate B1 is selectively distributed. Therefore, the board B1 passes the first and second mounting positions Pm1 and Pm2, and the component mounting to the plurality of mounting target points Bp of the board B1 is executed at the mounting position Pm3 downstream of the second mounting position Pm2. Be done. Further, with regard to the substrate B2 in transport order 1, among the three mounting positions Pm1, Pm2 and Pm3, the substrates are mounted at mounting positions Pm2 and Pm3 on the downstream side of the first mounting position Pm1 counting from the upstream side Component mounting to B2 is selectively distributed. Therefore, the substrate B1 passes the first mounting position Pm1, and component mounting to the plurality of mounting target points Bp of the substrate B2 is performed at the mounting positions Pm2 and Pm3 downstream of the first mounting position Pm1. . On the other hand, in the normal mounting mode, component mounting on the substrates B3 to B6 is distributed to each of the three mounting positions Pm1, Pm2 and Pm3, and the substrates B3 to B6 are sequentially arranged at the three mounting positions Pm1, Pm2 and Pm3. After stopping, component mounting to a plurality of mounting target points Bp of the substrates B3 to B6 is executed in order at each of the three mounting positions Pm1, Pm2 and Pm3.
 したがって、8枚の基板のうち搬送順序が最初の3枚の基板については、次のようにして部品実装が実行される。つまり、1番目の基板B1は、初期実装モードによって、基板搬送方向Xの上流側から数えて3番目の実装位置Pm3に搬送され、2番目の基板B2は、初期実装モードによって、基板搬送方向Xの上流側から数えて2番目の実装位置Pm2に搬送され、3番目の基板B3は、通常実装モードによって、基板搬送方向Xの上流側から数えて1番目の実装位置Pm1に搬送される。こうして、3個の実装位置Pm1、Pm2、Pm3のそれぞれに基板B3、B2、B1を搬送して、各実装位置Pm1、Pm2、Pm3で基板B3、B2、B1への部品実装を開始することができる。これによって、部品実装システム1の稼働率の低下を抑制することが可能となっている。 Therefore, component mounting is performed on the first three substrates out of the eight substrates in the following order. That is, the first substrate B1 is transported to the third mounting position Pm3 from the upstream side in the substrate transport direction X in the initial mounting mode, and the second substrate B2 is in the substrate transport direction X in the initial mounting mode. The third substrate B3 is transported to the first mounting position Pm1 from the upstream side in the substrate transfer direction X in the normal mounting mode by counting from the upstream side of the substrate and being transported to the second mounting position Pm2. Thus, the substrates B3, B2, B1 are transported to the three mounting positions Pm1, Pm2, Pm3 respectively, and component mounting on the substrates B3, B2, B1 can be started at the mounting positions Pm1, Pm2, Pm3. it can. By this, it is possible to suppress a decrease in the operation rate of the component mounting system 1.
 また、搬送部2は、基板搬送方向Xに隣り合う実装位置Pm1、Pm2、Pm3の間に配置された待機位置Pw1、Pw2をさらに有する。そして、基板搬送方向Xにおいて、3個の実装位置Pm1、Pm2、Pm3のうち、最下流の実装位置Pm3以外の実装位置Pm1、Pm2は、下流側で隣り合う実装位置Pm2、Pm3で部品実装が実行する場合には、分配された部品実装が完了した基板Bを下流側の待機位置Pw1、Pw2に搬出して、分配された部品実装が未完の基板Bを基板搬送方向Xの上流側から搬入する(動作A204~A205の基板B2、B4等)。かかる構成では、最下流の実装位置Pm3以外の実装位置Pm1、Pm2では、分配された部品実装が完了した基板Bを速やかに待機位置Pw1、Pw2に搬出され、部品実装が未完の次の基板Bが基板搬送方向Xの上流側から搬入される。その結果、部品実装システム1の稼働率の低下をより効果的に抑制することが可能となっている。 The transport unit 2 further includes standby positions Pw1 and Pw2 disposed between the mounting positions Pm1, Pm2 and Pm3 adjacent to each other in the substrate transport direction X. Of the three mounting positions Pm1, Pm2 and Pm3 in the substrate transport direction X, the mounting positions Pm1 and Pm2 other than the mounting position Pm3 at the most downstream are component mounting at mounting positions Pm2 and Pm3 adjacent on the downstream side In the case of execution, the substrate B for which the distributed component mounting has been completed is carried out to the standby positions Pw1 and Pw2 on the downstream side, and the substrate B for which the distributed component mounting is incomplete is carried in from the upstream side of the substrate transport direction X (Substrates B2 and B4 of operations A204 to A205, etc.). In this configuration, at the mounting positions Pm1 and Pm2 other than the most downstream mounting position Pm3, the distributed substrate mounting completed components B are promptly taken out to the standby positions Pw1 and Pw2, and the next substrate B whose component mounting is not completed is completed. Are loaded from the upstream side in the substrate transfer direction X. As a result, it is possible to more effectively suppress the decrease in the operation rate of the component mounting system 1.
 また、通常実装モードでは、実装位置Pm1、Pm2、Pm3のそれぞれで部品Wpが実装される実装対象点Bpの個数の差が1個以下となるように(上記の実施形態では、個数の差はゼロである)、3個の実装位置Pm1、Pm2、Pm3のそれぞれに基板Bへの部品実装が分配される。一方、初期実装モードでは、搬送順序1の基板B1に関して、基板搬送方向Xの上流側から数えて3番目の実装位置Pm3には、通常実装モードで基板搬送方向Xの上流側から数えて1番目から3番目までの実装位置Pm1、Pm2、Pm3に分配される部品実装が分配される。かかる構成では、仮に搬送順序1がM未満の基板B1に対して通常実装モードを実行した場合に、基板搬送方向Xの上流側から数えて1番目から3番目までの実装位置Pm1、Pm2、Pm3に分配される部品実装が、初期実装モードにおいて3番目の実装位置Pm3に分配される。つまり、初期実装モードでは、搬送順序1の基板B1に関して、3番目の実装位置Pm3より上流側の実装位置Pm1、Pm2での部品実装が省略されるものの、この部品実装を3番目の実装位置Pm3で確実に実行することが可能となっている。 Further, in the normal mounting mode, the difference in the number of mounting target points Bp on which the component Wp is mounted at each of the mounting positions Pm1, Pm2 and Pm3 is 1 or less (in the above embodiment, the difference in the number is Component mounting on the substrate B is distributed to each of the three mounting positions Pm1, Pm2 and Pm3). On the other hand, in the initial mounting mode, the third mounting position Pm3 counted from the upstream side in the substrate conveyance direction X with respect to the substrate B1 in the conveyance order 1 is counted from the upstream side in the substrate conveyance direction X in the normal mounting mode The component mounting distributed to the third to third mounting positions Pm1, Pm2, and Pm3 is distributed. In this configuration, if the normal mounting mode is executed on a substrate B1 having a transport order 1 less than M, the first to third mounting positions Pm1, Pm2, and Pm3 counted from the upstream side in the substrate transport direction X The component mounting distributed to is distributed to the third mounting position Pm3 in the initial mounting mode. That is, in the initial mounting mode, with regard to the substrate B1 of transport order 1, although component mounting at the mounting positions Pm1 and Pm2 upstream of the third mounting position Pm3 is omitted, this component mounting is performed at the third mounting position Pm3 It is possible to execute with
 また、初期実装モードでは、搬送順序2の基板B2に関して、基板搬送方向Xの上流側から数えて2番目の実装位置Pm2には、通常実装モードで基板搬送方向Xの上流側から数えて1番目から2番目までの実装位置Pm1、Pm2に分配される部品実装が分配される。かかる構成では、仮に搬送順序2がM未満の基板B2に対して通常実装モードを実行した場合に、基板搬送方向Xの上流側から数えて1番目から2番目までの実装位置Pm1、Pm2に分配される部品実装が、初期実装モードにおいて2番目の実装位置Pm2に分配される。つまり、初期実装モードでは、搬送順序2の基板B2に関して、2番目の実装位置Pm3より上流側の実装位置Pm1での部品実装が省略されるものの、この部品実装を2番目の実装位置Pm2で確実に実行することが可能となっている。 In the initial mounting mode, the second mounting position Pm2 from the upstream side in the substrate conveyance direction X with respect to the substrate B2 in the conveyance order 2 is the first from the upstream side in the substrate conveyance direction X in the normal mounting mode. The component mountings distributed to the second to the second mounting positions Pm1 and Pm2 are distributed. In this configuration, if the normal mounting mode is executed for a substrate B2 having a transport order 2 less than M, distribution to the first to second mounting positions Pm1 and Pm2 counted from the upstream side in the substrate transport direction X is performed. Component mounting is distributed to the second mounting position Pm2 in the initial mounting mode. That is, in the initial mounting mode, component mounting at the mounting position Pm1 on the upstream side of the second mounting position Pm3 is omitted for the substrate B2 in transport order 2, but this component mounting is assured at the second mounting position Pm2. It is possible to carry out.
 また、制御部100は、8枚の基板B1~B8のうち搬送順序Nが(L-M+2)番以上の基板B7、B8に対しては終期実装モード(動作A209~A216における基板B7、B8に対する動作)で部品実装を実行する。つまり、この終期実装モードでは、搬送順序7の基板B7に関して、3個の実装位置Pm1、Pm2、Pm3のうち基板搬送方向Xの上流側から数えて1番目から2番目までの実装位置Pm1、Pm2に基板B7への部品実装が選択的に分配され、1番目から2番目までの実装位置Pm1、Pm2で基板B7の複数の実装対象点Bpへの部品実装が実行される。したがって、基板搬送方向Xにおいて、2番目より下流側の実装位置Pm3で部品実装を実行中であっても、1番目から2番目までの実装位置Pm1、Pm2を稼動させて、搬送順序Nが7番の基板B7に対して部品実装を効率的に実行できる。また、搬送順序8の基板B8に関して、3個の実装位置Pm1、Pm2、Pm3のうち基板搬送方向Xの上流側から数えて1番目の実装位置Pm1に基板B8への部品実装が選択的に分配され、1番目の実装位置Pm1で基板B8の複数の実装対象点Bpへの部品実装が実行される。したがって、基板搬送方向Xにおいて、1番目より下流側の実装位置Pm2、Pm3で部品実装を実行中であっても、1番目の実装位置Pm1を稼動させて、搬送順序Nが8番の基板B8に対して部品実装を効率的に実行できる。その結果、部品実装システムの稼働率の低下をより効果的に抑制することが可能となっている。 In addition, the control unit 100 sets the final mounting mode for substrates B7 and B8 having a transport order N of (L−M + 2) or higher among the eight substrates B1 to B8 (for substrates B7 and B8 in operations A209 to A216). Execute component mounting in (operation). That is, in the final mounting mode, of the three mounting positions Pm1, Pm2 and Pm3 with respect to the substrate B7 in the conveyance order 7, the first to second mounting positions Pm1 and Pm2 from the upstream side in the substrate conveyance direction X Component mounting on the substrate B7 is selectively distributed, and component mounting on a plurality of mounting target points Bp of the substrate B7 is executed at the first to second mounting positions Pm1 and Pm2. Therefore, even if component mounting is being performed at the mounting position Pm3 downstream of the second in the substrate transfer direction X, the first to second mounting positions Pm1 and Pm2 are operated, and the transfer order N is 7 Component mounting can be efficiently performed on the board B7 of Further, with regard to the substrate B8 in the transport order 8, among the three mounting positions Pm1, Pm2 and Pm3, the component mounting on the substrate B8 is selectively distributed to the first mounting position Pm1 counting from the upstream side in the substrate transport direction X. Thus, component mounting to a plurality of mounting target points Bp of the substrate B8 is performed at the first mounting position Pm1. Therefore, even while component mounting is being performed at the mounting positions Pm2 and Pm3 downstream of the first in the substrate conveyance direction X, the first mounting position Pm1 is operated, and the substrate B8 having the eighth conveyance order N is Component mounting can be performed efficiently. As a result, it is possible to more effectively suppress the decrease in the operation rate of the component mounting system.
 また、終期実装モードでは、搬送順序7の基板B7に関して、基板搬送方向Xの上流側から数えて2番目の実装位置Pm2には、通常実装モードで基板搬送方向Xの上流側から数えて2番目から3番目までの実装位置Pm2、Pm3に分配される部品実装が分配される。かかる構成では、仮に搬送順序7の基板B7に対して通常実装モードを実行した場合に、基板搬送方向Xの上流側から数えて2番目から3番目までの実装位置Pm2、Pm3に分配される部品実装が、終期実装モードにおいて2番目の実装位置Pm2に分配される。つまり、終期実装モードでは、搬送順序7の基板B7に関して、2番目の実装位置Pm2より下流側の実装位置Pm3での部品実装が省略されるものの、この部品実装を2番目の実装位置Pm2で確実に実行することが可能となっている。 In the final mounting mode, the second mounting position Pm2 counted from the upstream side in the substrate conveyance direction X with respect to the substrate B7 in the conveyance order 7 is counted from the upstream side in the substrate conveyance direction X in the normal mounting mode The component mounting distributed to the third to third mounting positions Pm2 and Pm3 is distributed. In this configuration, if the normal mounting mode is executed for the substrate B7 in the conveyance order 7, the components distributed to the second to third mounting positions Pm2 and Pm3 from the upstream side in the substrate conveyance direction X The implementation is distributed to the second implementation position Pm2 in the final implementation mode. That is, in the final mounting mode, with regard to the substrate B7 having the conveyance order 7, component mounting at the mounting position Pm3 downstream from the second mounting position Pm2 is omitted, but this component mounting is assured at the second mounting position Pm2 It is possible to carry out.
 また、終期実装モードでは、搬送順序8の基板B8に関して、基板搬送方向Xの上流側から数えて1番目の実装位置Pm1には、通常実装モードで基板搬送方向Xの上流側から数えて1番目から3番目までの実装位置Pm1、Pm2、Pm3に分配される部品実装が分配される。かかる構成では、仮に搬送順序8の基板B8に対して通常実装モードを実行した場合に、基板搬送方向Xの上流側から数えて1番目から3番目までの実装位置Pm1、Pm2、Pm3に分配される部品実装が、終期実装モードにおいて1番目の実装位置Pm1に分配される。つまり、終期実装モードでは、搬送順序8の基板B8に関して、1番目の実装位置Pm1より下流側の実装位置Pm2、Pm3での部品実装が省略されるものの、この部品実装を1番目の実装位置Pm1で確実に実行することが可能となっている。 In the final mounting mode, the first mounting position Pm1 counted from the upstream side in the substrate conveyance direction X with respect to the substrate B8 in the conveyance order 8 is counted from the upstream side in the substrate conveyance direction X in the normal mounting mode The component mounting distributed to the third to third mounting positions Pm1, Pm2, and Pm3 is distributed. In this configuration, if the normal mounting mode is executed for the substrate B8 in the transport order 8, it is distributed to the first to third mounting positions Pm1, Pm2, and Pm3 counted from the upstream side in the substrate transport direction X. Component mounting is distributed to the first mounting position Pm1 in the final mounting mode. That is, in the final mounting mode, with regard to the substrate B8 in the conveyance order 8, although the component mounting at the mounting positions Pm2 and Pm3 downstream of the first mounting position Pm1 is omitted, this component mounting is the first mounting position Pm1 It is possible to execute with
 ところで、上述の第1例あるいは第2例の実行中に、いずれかの実装位置Pmでの部品実装の進捗が予定より遅れる場合がある。そこで、次に示すように、かかる進捗の遅れをリカバリーするように構成しても良い。 By the way, during the execution of the first example or the second example described above, the progress of component mounting at any mounting position Pm may be delayed from a schedule. Therefore, as shown below, it may be configured to recover such a delay in progress.
 図7は部品実装の進捗のリカバリーを実行可能な部品実装処理の一例を示すフローチャートであり、図8は図7に示す部品実装処理でのリカバリー要否判定の一例を示すフローチャートであり、図9は図7および図8のフローチャートに従って実行される動作の一例を模式的に示す図である。図9に示すように、ここで示す例では、搬送部2は2個の実装位置Pm1、Pm2が設けられている。 FIG. 7 is a flowchart showing an example of component mounting processing capable of executing recovery of the progress of component mounting, and FIG. 8 is a flowchart showing an example of recovery necessity determination in the component mounting processing shown in FIG. 8 schematically shows an example of an operation performed according to the flowcharts of FIG. 7 and FIG. As shown in FIG. 9, in the example shown here, the transport unit 2 is provided with two mounting positions Pm1 and Pm2.
 制御部100は、実装位置Pm1、Pm2のそれぞれについて図7および図8のフローチャートを実行することで、図9および図10の動作を実行する。つまり、図7に示すように、部品実装処理が開始すると、上述の第1例と同様にして、実装位置Pmに基板Bが搬入され(ステップS301)、実装位置Pmに部品実装が分配される(ステップS302)。そして、いずれかの実装位置Pmで部品実装が完了すると(ステップS303)、各実装位置Pmについてリカバリー要否判定が実行される(ステップS304、図8)。 The control unit 100 executes the operations of FIGS. 9 and 10 by executing the flowcharts of FIGS. 7 and 8 for each of the mounting positions Pm1 and Pm2. That is, as shown in FIG. 7, when the component mounting process is started, the substrate B is carried to the mounting position Pm (step S301) and the component mounting is distributed to the mounting position Pm as in the first example described above. (Step S302). Then, when component mounting is completed at any mounting position Pm (step S303), recovery necessity determination is performed for each mounting position Pm (step S304, FIG. 8).
 図9に示す例では、動作A103までは、上記の第1例と同様に実行されている。つまり、実装位置Pm2には、実装位置Pm1への通常分配点(上流側半分)へ部品Wpが実装された基板B1が搬入され、待機位置Pwでは、実装位置Pm1への通常分配点(上流側半分)へ部品Wpが実装された基板B2が待機し、実装位置Pm1には、基板B3が搬入されている。また、実装位置Pm2では、基板B1の複数の実装対象点Bpのうち実装位置Pm2への通常分配点(下流側半分)への部品実装が分配され、実装位置Pm1では、基板B3の複数の実装対象点Bpのうち実装位置Pm1への通常分配点(上流側半分)への部品実装が分配される。 In the example shown in FIG. 9, the operations up to the operation A103 are performed in the same manner as the first example described above. That is, the board B1 on which the component Wp is mounted is carried to the mounting position Pm2 at the normal distribution point (upstream half) to the mounting position Pm1, and at the standby position Pw, the normal distribution point to the mounting position Pm1 (upstream The substrate B2 on which the component Wp is mounted is on standby, and the substrate B3 is carried to the mounting position Pm1. Further, at the mounting position Pm2, component mounting to the normal distribution point (downstream half) to the mounting position Pm2 among the plurality of mounting target points Bp of the substrate B1 is distributed, and at the mounting position Pm1, a plurality of mountings of the substrate B3 Component mounting to the normal distribution point (upstream half) of the target point Bp to the mounting position Pm1 is distributed.
 この状態から、実装位置Pm1、Pm2での部品実装を開始した結果が、図9の動作A111の欄に示される。実装位置Pm2では、基板B1への部品実装が完了している。したがって、この部品実装の完了時点で、ステップS304(図8)のリカバリー要否判定が実装位置Pm1、Pm2のそれぞれについて実行される。 The result of starting component mounting at the mounting positions Pm1 and Pm2 from this state is shown in the column of operation A111 in FIG. At the mounting position Pm2, component mounting on the substrate B1 is completed. Therefore, when the component mounting is completed, the recovery necessity / non-necessity determination in step S304 (FIG. 8) is executed for each of the mounting positions Pm1 and Pm2.
 具体的には、実装位置Pm2について、実装位置Pm2の下流に基板Bが存在するかが判断される(ステップS401)。実装位置Pm2の下流に基板Bは存在しないため(ステップS401で「NO」)、ステップS402で、実装位置Pm2の部品実装の進捗に遅れがあるかが判断される。進捗に遅れはないため(ステップS402で「NO」)、ステップS404でリカバリー不要と判断され、図7フローチャートに戻る。 Specifically, for the mounting position Pm2, it is determined whether or not the substrate B is present downstream of the mounting position Pm2 (step S401). Since the substrate B does not exist downstream of the mounting position Pm2 ("NO" in step S401), it is determined in step S402 whether there is a delay in the progress of component mounting at the mounting position Pm2. Since the progress is not delayed ("NO" in step S402), it is determined in step S404 that recovery is unnecessary, and the process returns to the flowchart of FIG.
 つまり、図7のステップS304では「不要」に分岐して、各実装位置Pm2について、実装完了時判断処理(図3)が実行される(ステップS306)。その結果、動作A112の欄に示すように、基板B1が実装位置Pm2から搬出されるとともに、基板B2が待機位置Pwから実装位置Pm2に搬入される。また、実装位置Pm2には、基板B2の複数の実装対象点Bpのうち実装位置Pm2への通常分配点への部品実装が分配される。 That is, in step S304 of FIG. 7, the process branches to “unnecessary”, and the mounting completion determination process (FIG. 3) is executed for each mounting position Pm2 (step S306). As a result, as shown in the column of the operation A112, the substrate B1 is unloaded from the mounting position Pm2, and the substrate B2 is loaded from the standby position Pw to the mounting position Pm2. Further, component mounting to the normal distribution point to the mounting position Pm2 among the plurality of mounting target points Bp of the substrate B2 is distributed to the mounting position Pm2.
 さらに、実装位置Pm1について、実装位置Pm1の下流に基板Bが存在するかが判断される(ステップS401)。待機位置Pwの基板B2は、基板B1の搬出とともに実装位置Pm2に搬送されるため(ステップS401で「NO」)、ステップS402で、実装位置Pm1の部品実装の進捗に遅れがあるかが判断される。実装位置Pm1では、基板B3での部品実装の進捗に遅れがあるため(ステップS402で「YES」)、ステップS403で、残りの実装点数が閾値(例えば、通常分配点の数の半分)以上かが判断される。残りの実装点数が閾値未満である場合(ステップS403で「NO」の場合)には、ステップS404でリカバリー不要と判断される。一方、ここの例のように、残りの実装点数が閾値以上である場合(ステップS403で「YES」の場合)には、ステップS405でリカバリーが必要と判断され、図7のフローチャートに戻る。 Further, with regard to the mounting position Pm1, it is determined whether or not the substrate B exists downstream of the mounting position Pm1 (step S401). The board B2 at the standby position Pw is transported to the mounting position Pm2 along with unloading of the board B1 (“NO” in step S401), so it is determined in step S402 whether there is a delay in the progress of component mounting at the mounting position Pm1. Ru. At the mounting position Pm1, there is a delay in the progress of component mounting on the substrate B3 (“YES” in step S402). Therefore, in step S403, whether the remaining mounting points are at least a threshold (for example, half the number of normal distribution points) Is judged. If the remaining mounting score is less than the threshold (in the case of "NO" in step S403), it is determined in step S404 that recovery is unnecessary. On the other hand, as in this example, if the remaining mounting score is equal to or greater than the threshold (in the case of “YES” in step S403), it is determined in step S405 that recovery is necessary, and the process returns to the flowchart of FIG.
 つまり、図7のステップS304では、「必要」に分岐して、部品実装が再分配される(ステップS305)。具体的には、実装位置Pm1に停止する基板B3について、実装位置Pm1の通常分配点の一部(ここでは、半分)が実装位置Pm1から実装位置Pm2へ移される。そして、実装位置Pm1について、実装完了時判断処理(図3)が実行される(ステップS306)。その結果、動作A112の欄に示すように、基板B3は実装位置Pm1に留まる。また、実装位置Pm1では、基板B3の複数の実装対象点Bpのうち実装位置Pm1への通常分配点の半分への部品実装が分配されて、ステップS306からステップS303に戻る。 That is, in step S304 of FIG. 7, the process branches to "necessary", and component mounting is redistributed (step S305). Specifically, for the substrate B3 stopped at the mounting position Pm1, part (here, half) of the normal distribution point of the mounting position Pm1 is moved from the mounting position Pm1 to the mounting position Pm2. Then, the mounting completion determination process (FIG. 3) is executed for the mounting position Pm1 (step S306). As a result, as shown in the column of operation A112, the substrate B3 remains at the mounting position Pm1. Further, at the mounting position Pm1, the component mounting to the half of the normal distribution point to the mounting position Pm1 is distributed among the plurality of mounting target points Bp of the substrate B3, and the process returns from step S306 to step S303.
 図9の動作A113の欄に示すように、実装位置Pm1で分配された部品実装が基板B3に対して完了すると(ステップS303)、リカバリー要否判定が各実装位置Pm1、Pm2について実行される。実装位置Pm1、Pm2のいずれにおいても、部品実装の進捗に遅れはないため(ステップS402で「NO」)、ステップS404でリカバリー不要と判断され、図7のフローチャートに戻る。そして、実装位置Pm1、Pm2のそれぞれについて、ステップS304で「不要」に分岐して、ステップS306で「実装完了時判断処理」が実行される。その結果、図9の動作A114の欄に示すように、基板B3が待機位置Pwに搬出され、基板B4が実装位置Pm1に搬入される。また、実装位置Pm1では、基板B4の複数の部品Wpのうち、実装位置Pm1への通常分配点への部品実装が分配される。 As shown in the column of operation A113 in FIG. 9, when the component mounting distributed at the mounting position Pm1 is completed on the substrate B3 (step S303), recovery necessity determination is performed for each mounting position Pm1 and Pm2. Since there is no delay in the progress of component mounting at any of the mounting positions Pm1 and Pm2 (“NO” in step S402), it is determined in step S404 that recovery is unnecessary, and the process returns to the flowchart of FIG. Then, for each of the mounting positions Pm1 and Pm2, the process branches to “unnecessary” in step S304, and “mounting completion determination processing” is executed in step S306. As a result, as shown in the column of operation A114 in FIG. 9, the substrate B3 is carried out to the standby position Pw, and the substrate B4 is carried in to the mounting position Pm1. Further, at the mounting position Pm1, among the plurality of components Wp of the substrate B4, component mounting to the normal distribution point at the mounting position Pm1 is distributed.
 図9の動作A115の欄に示すように、実装位置Pm2で分配された部品実装が基板B2に対して完了すると(ステップS303)、リカバリー要否判定が各実装位置Pm1、Pm2について実行される。実装位置Pm1、Pm2のいずれにおいても、部品実装の進捗に遅れはないため(ステップS402で「NO」)、ステップS404でリカバリー不要と判断され、図7のフローチャートに戻る。そして、実装位置Pm1、Pm2のそれぞれについて、ステップS304で「不要」に分岐して、ステップS306で「実装完了時判断処理」が実行される。その結果、図9の動作A116の欄に示すように、基板B3が実装位置Pm2に搬入される。また、実装位置Pm2では、基板B3の複数の実装対象点Bpのうち、実装位置Pm2への通常分配点と、先のステップS305で写された、実装位置Pm1への通常分配点の半分の分配点とが分配される。したがって、図9の動作A117の欄に示すように、実装位置Pm2では、実装位置Pm1への通常分配点の半分の分配点に対して部品Wp(ハッチングが施された部品Wp)が、基板B3に対して実装される。 As shown in the column of operation A115 of FIG. 9, when the component mounting distributed at the mounting position Pm2 is completed on the substrate B2 (step S303), recovery necessity determination is performed for each mounting position Pm1 and Pm2. Since there is no delay in the progress of component mounting at any of the mounting positions Pm1 and Pm2 (“NO” in step S402), it is determined in step S404 that recovery is unnecessary, and the process returns to the flowchart of FIG. Then, for each of the mounting positions Pm1 and Pm2, the process branches to “unnecessary” in step S304, and “mounting completion determination processing” is executed in step S306. As a result, as shown in the column of operation A116 in FIG. 9, the substrate B3 is carried into the mounting position Pm2. Further, at the mounting position Pm2, among the plurality of mounting target points Bp of the substrate B3, distribution of the normal distribution point to the mounting position Pm2 and distribution of half of the normal distribution points to the mounting position Pm1 copied in the previous step S305. Points are distributed. Therefore, as shown in the column of operation A117 in FIG. 9, at the mounting position Pm2, the component Wp (the hatched component Wp) with respect to the distribution point of half of the normal distribution point to the mounting position Pm1 is the substrate B3. Will be implemented for
 このように、制御部100は、M個の実装位置Pm1、Pm2のうち、一の実装位置Pm1および他の実装位置Pm2の少なくとも一方の実装位置Pm1での部品実装の進捗に応じて、一の実装位置Pm1と他の実装位置Pm2との間での部品実装の分配を調整する。かかる構成では、一の実装位置Pm1での部品実装の進捗が例えば予定より遅い場合に、一の実装位置Pm1に分配予定であった部品実装を他の実装位置Pm2に分配するといったことができる。これによって、各実装位置Pm1、Pm2での部品実装の進捗のバランスを取ることが可能となっている。 Thus, control unit 100 selects one of M mounting positions Pm 1 and Pm 2 according to the progress of component mounting at one mounting position Pm 1 and at least one other mounting position Pm 2 of mounting positions Pm 1 and Pm 2. The distribution of component mounting between the mounting position Pm1 and the other mounting position Pm2 is adjusted. In such a configuration, when the progress of component mounting at one mounting position Pm1 is later than scheduled, for example, the component mounting that is scheduled to be distributed to one mounting position Pm1 can be distributed to another mounting position Pm2. This makes it possible to balance the progress of component mounting at each of the mounting positions Pm1 and Pm2.
