Abstract
Description
1-1.基板生産ライン1の構成例
図1に示すように、基板生産ライン1は、少なくとも一つ(同図では、4つ)の部品装着機10と、交換システム30と、物品移動装置40と、保管装置5と、ライン制御コンピュータ6とを備えている。4つの部品装着機10は、図2に示す基板90の搬送方向に沿って設置されている。部品装着機10は、基板90に所定の対基板作業を行う対基板作業機WMに含まれる。部品装着機10による対基板作業には、基板90の搬入作業および搬出作業、部品の採取作業および装着作業などが含まれる。部品装着機10には、例えば、カセット式のフィーダ20が着脱可能に設けられる。
図2に示すように、4つの部品装着機10の各々は、基板搬送装置11と、部品供給装置12と、ヘッド駆動装置13とを備えている。以下の説明において、部品装着機10の水平幅方向であり基板90の搬送方向をX方向とし、部品装着機10の水平奥行き方向をY方向とし、X方向およびY方向に垂直な鉛直方向(図2の紙面上下方向)をZ方向とする。
図3に示すように、フィーダ20は、フィーダ本体21と、駆動装置22とを備えている。本実施形態のフィーダ本体21は、扁平な箱形状に形成されている。フィーダ本体21は、多数の部品を収容するキャリアテープが巻回されたリールを着脱可能(交換可能)に保持する。駆動装置22は、キャリアテープに設けられた送り穴に係合するスプロケットを備えている。駆動装置22は、スプロケットを回転させてキャリアテープを送り移動させる。
図1および図2に示すように、交換システム30は、第一レール31と、第二レール32とを備えている。第一レール31および第二レール32は、物品移動装置40の走行路を形成する。第一レール31は、4つの部品装着機10の配置方向に沿って設けられ、上下方向(Z方向)において、第一スロット121と、第二スロット122との間に設けられている。第二レール32は、4つの部品装着機10の配置方向に沿って設けられ、上下方向(Z方向)において、第二スロット122の下方に設けられている。第一レール31および第二レール32は、基板生産ライン1において、基板90の搬送方向の概ね全域に亘って延伸している。
基板生産ライン1では、部品装着機10は、物品移動装置40によるフィーダ20の供給を受けつつ基板製品の生産を行う。そのため、部品装着機10の稼働状況の経時変化および物品移動装置40の稼働状況の経時変化を把握したいという要請がある。そこで、本実施形態では、シミュレーション装置50が設けられている。
模擬部51は、基板90に所定の対基板作業を行って基板製品を生産する対基板作業機WMの稼働状況、および、基板製品の生産に必要な物品AR0を対基板作業機WMに供給する物品移動装置40の稼働状況を、基板製品の生産計画に基づいてシミュレーションする(図6に示すステップS11~ステップS16)。
出力部52は、模擬部51によるシミュレーション結果である対基板作業機WMの稼働状況の経時変化および物品移動装置40の稼働状況の経時変化を示す時系列情報を出力する(図6に示すステップS17)。
表示部53は、出力部52によって出力された時系列情報に基づいて、第一稼働時間帯TD1および第一停止時間帯TN1と、第二稼働時間帯TD2および第二停止時間帯TN2とを対比可能に表示装置7DPにタイムライン表示させる(図6に示すステップS18)。
図1に示すように、本実施形態では、保管装置5は、基板生産ライン1に設けられ、物品移動装置40は、交換システム30の第一レール31および第二レール32によって形成される走行路に沿って走行することができる。しかしながら、保管装置5および物品移動装置40は、上記形態に限定されるものではなく、種々の形態をとり得る。例えば、保管装置5は、基板生産ライン1から離間した位置に設けることができ、複数の基板生産ライン1に物品AR0を供給し、複数の基板生産ライン1から物品AR0を回収することもできる。
シミュレーション装置50について既述したことは、シミュレーション方法についても同様に言える。具体的には、シミュレーション方法は、模擬工程と、出力工程とを備えている。模擬工程は、模擬部51が行う制御に相当する。出力工程は、出力部52が行う制御に相当する。シミュレーション方法は、表示工程をさらに備えることができる。表示工程は、表示部53が行う制御に相当する。
シミュレーション装置50は、模擬部51および出力部52を備える。よって、シミュレーション装置50は、対基板作業機WMの稼働状況の経時変化および物品移動装置40の稼働状況の経時変化を出力することができる。シミュレーション装置50について上述したことは、シミュレーション方法についても同様に言える。
