図1、図2及び図3を用いて、自動倉庫100のシステム構成の概要が説明される。図1は、自動倉庫100の内部の一例を概略的に示す。図2は、自動倉庫100のシステム構成の一例を概略的に示す。図3は、自動倉庫100におけるコンテナの保管方法の一例を概略的に示す。
複数のラック130のそれぞれは、例えば、各ラックが所定の位置に設置された場合に、上下方向に積み上げられた複数のコンテナ120の一部を側方又は下方から支持することができるように構成される。例えば、図3に示されるとおり、コンテナ120の外側の側面には、複数の切欠部124が形成される。本実施形態によれば、複数の切欠部124のそれぞれの一部がラック130の一部に嵌め込まれるように配置されることで、ラック130が、コンテナ120を下方から支持する。これにより、ラック130の予め定められた支持位置において、コンテナ120の下方向の移動が抑制され、コンテナ120がラック130に保管され得る。
本実施形態において、自動倉庫100は、複数のコンテナ120を、上下方向に積み上げて保管することができる。上下方向に一列に積み上げられた複数のコンテナ120は、例えば、ラック130により、床10から予め定められた高さに支持される。これにより、ラック130に支持されたコンテナ120の下方の空間が、他のコンテナ120の搬送経路として利用され得る。
[コンテナ120]
本実施形態において、1以上のコンテナ120のそれぞれは、1以上の物品を収容するために用いられる。コンテナ120の材質、形状及び大きさは、例えば、物品の保管効率及びハンドリングの容易性を考慮して決定される。コンテナ120の形状及び大きさは、特に制限されるものではないが、例えば、幅が20cm~1mであり、高さが20cm~1mであり、奥行が20cm~1mである。コンテナ120の詳細は後述される。
本実施形態において、1以上のラック130のそれぞれは、1以上のコンテナ120を支持する。例えば、ラック130は、一列に積み上げられた複数のコンテナ120を支持する。
本実施形態において、ラック130のフレーム222は、コンテナ120の外側の一部を下方から支持することで、コンテナ120を所定の位置に支持する。フレーム222は、コンテナ120の外側の底面の一部を下方から支持してもよく、コンテナ120の外側の側面の一部を下方から支持してもよい。フレーム222は、コンテナ120を少なくとも2点で支持してよい。フレーム222は、コンテナ120を3点で支持してもよく、4点で支持してもよい。フレーム222は、コンテナ120を5点以上の位置で支持してもよい。
本実施形態において、ラック130のフレームサポート224は、フレーム222と、床10との間に配される。フレームサポート224は、フレーム222が受けた1以上のコンテナ120の荷重を、床10に伝達する。フレームサポート224は、フレーム222を、上述された所定の高さに配置する。
本実施形態において、ラック130のワイヤ232は、フレーム222よりも上方に配される。ラック130は、複数のワイヤ232を有してもよい。複数のワイヤ232が、マトリックス状に配された複数のラック130の各列又は各行の上方に配されてもよい。複数のワイヤ232が、複数のワイヤ232が、マトリックス状に配された複数のラック130の複数の列の一部又は複数の行の一部の上方に配されてもよい。1又は複数のワイヤ232が、マトリックス状に配された複数のラック130の外周の上方を囲うように配されてよい。これにより、ラック130に支持された1以上のコンテナ120の転倒又は倒壊が抑制され得る。
本実施形態において、ラック130のワイヤーサポート234は、1又は複数のワイヤ232を支持する。ワイヤーサポート234は、1又は複数のワイヤ232を所定の高さに配置する。ラック130は、複数のワイヤーサポート234を有してもよい。これにより、ラック130に支持された1以上のコンテナ120の転倒又は倒壊が抑制され得る。
本実施形態において、搬送車140は、第1の位置と、第2の位置との間で、少なくとも1つのコンテナ120を搬送する。第1の位置及び第2の位置は、自動倉庫100の内部の異なる位置であってよい。本実施形態において、搬送車140は、ラック130との間でコンテナ120を移載する。一実施形態において、搬送車140は、ラック130にコンテナ120を積み込む。他の実施形態において、搬送車140は、ラック130からコンテナ120を取り出す。
本実施形態において、ピッキング装置150は、一のコンテナ120と、他のコンテナ120との間で、物品を移載する。一実施形態において、ピッキング装置150は、搬送車242に搭載されたコンテナ120に収容されている物品を取り出し、当該物品を、搬送車244に搭載されたコンテナ120に収容する。他の実施形態において、ピッキング装置150は、搬送車244に搭載されたコンテナ120に収容されている物品を取り出し、当該物品を、搬送車242に搭載されたコンテナ120に収容する。
本実施形態において、管理サーバ160は、物品の保管状況を管理する。管理サーバ160は、自動倉庫100の各部を管理してもよい。例えば、管理サーバ160は、自動倉庫100の各部の状態を管理する。管理サーバ160は、管理サーバ160は、1以上の搬送車140のそれぞれの運転を管理してもよい。管理サーバ160は、1以上のラック130のそれぞれの運転を管理してもよい。
自動倉庫100の各部は、ハードウエアにより実現されてもよく、ソフトウエアにより実現されてもよく、ハードウエア及びソフトウエアにより実現されてもよい。自動倉庫100の各部は、その少なくとも一部が、単一のサーバによって実現されてもよく、複数のサーバによって実現されてもよい。自動倉庫100の各部は、その少なくとも一部が、仮想サーバ上又はクラウドシステム上で実現されてもよい。
図12、図13、図14、図15及び図16を用いて、自動倉庫100におけるコンテナ120の格納手順の詳細が説明される。図12~図16は、格納処理の対象となるコンテナ120が格納される直前の時点において、ラック130がコンテナ120を支持していない場合における、コンテナ120の格納手順の一例を示す。
図17、図18、図19、図20、図21、図22及び図23を用いて、自動倉庫100におけるコンテナ120の格納手順の他の例が説明される。図17~図23は、格納処理の対象となるコンテナ120が格納される直前の時点において、ラック130が既に1以上のコンテナ120を支持している場合における、コンテナ120の格納手順の一例を示す。
図24は、コンテナ120の取出手順の一例を概略的に示す。図24は、一列に積み上げられた複数のコンテナ120の中から、目的とするコンテナ120を取り出す手順の一例を示す。
本実施形態においては、説明を簡単にすることを目的として、コンテナ120を搭載していない搬送車140が、一度に1つのコンテナ120を取り出す場合を例として、S2432におけるコンテナ120の取出手順の一例が説明される。しかしながら、コンテナ120の取出手順は本実施形態に限定されない。他の実施形態において、搬送車140は、一度に複数のコンテナ120が取り出されてよい。さらに他の実施形態において、少なくとも1つの他のコンテナ120を搭載した搬送車140が、目的とするコンテナ120を取り出してもよい。
本実施形態においては、説明を簡単にすることを目的として、ラック130が単一のコンテナ120を支持している場合に、コンテナ120を搭載していない搬送車140が、ラック130に支持されているコンテナ120(コンテナTと称される場合がある。)を取り出す場合を例として、S2434におけるコンテナ120の取出手順の一例が説明される。しかしながら、コンテナ120の取出手順は本実施形態に限定されない。他の実施形態において、少なくとも1つの他のコンテナ120を搭載した搬送車140が、目的とするコンテナ120を取り出してよい。
