Description

【０００１】
【発明の属する技術分野】
本発明はクリーンルーム等で使用される自動倉庫に関し、詳しくは該自動倉庫の収納部の構成に関する。
【０００２】
【従来の技術】
従来より、物品を搬送するためのスタッカクレーンを備えた自動倉庫が知られている。この自動倉庫では、物品を収納するための収納棚を水平方向及び垂直方向に備えたラックが一対設けられ、その間にレールが敷設され、レール上をスタッカクレーンが走行するように構成されている。スタッカクレーンは、レールに沿って走行する搬送台車を有し、搬送台車にはマストが立設されており、さらに、マストに沿って昇降する昇降台が設けられている。そして、昇降台には、水平方向に伸縮自在な移載装置が設けられ、該移載装置により物品が収納棚に載置される。
前記ラックは、前後（物品を出し入れする方向）に並ぶ一対の支柱の両側面又は一側面に、多数の棚部材を上下方向に架設した支柱ユニットを、複数並設して構成されている。前記一対の支柱は棚部材の前後端に取り付けられ、前記収納棚は隣り合う支柱ユニットにそれぞれ取り付けられる一対の棚部材で構成され、物品は該一対の棚部材をまたぐように載置される。
【０００３】
【発明が解決しようとする課題】
近年は、両側面に把手部などの突出部を有する物品も増え、該物品を収納する際、該突出部が前後の支柱と干渉しないように、この突出分を含めて左右方向に支柱ユニットの間隔が拡幅されている。このため、一物品当たりの収納スペースが増大し、収納効率が良くなかった。
勿論、この自動倉庫には突出部を有しない物品も収納され、本発明では、自動倉庫の収納効率の向上を図ることを課題とする。
【０００４】
【課題を解決するための手段】
本発明の解決しようとする課題は以上の如くであり、次に該課題を解決するための手段を説明する。
【０００５】
まず、請求項１に記載のように、物品の出し入れ方向奥側に配置された、物品の出し入れ方向と平面視で直交する方向の側面に取付溝を有するとともに物品の出し入れ方向奥側の背面に係合片を有する第１の支柱と、前記第１の支柱に寄せて第１の支柱の物品の出し入れ方向手前に配置された、物品の出し入れ方向と平面視で直交する方向の側面に取付溝を有する第２の支柱と、前記第１の支柱の取付溝と前記第２の支柱の取付溝とに架け渡されて固定具を介して取り付けられる棚部材と、前記棚部材が上下方向に複数取り付けられた第１及び第２の支柱を、物品の出し入れ方向と平面視で直交する方向に複数並設して構成された物品収納部と、前記第１の支柱の取付溝に取り付けられて、物品の出し入れ方向と平面視で直交する方向に隣り合う第１の支柱間を接続する、上下面に挿入溝を有する繋ぎ部材と、前記繋ぎ部材の挿入溝に挿入されるとともに前記第１の支柱の係合片と係合させて取り付けられる外壁パネルと、を備えた自動倉庫とする。
【０００６】
そして、請求項２に記載のように、前記第１の支柱と前記第２の支柱とは一体形成され、該第１の支柱と該第２の支柱との間に、床面に対して位置決めする位置決め部材の挿入孔を形成した。
【０００７】
また、請求項３に記載のように、前記第１の支柱の背面の係合片は物品の出し入れ方向と平面視で直交する方向に一対形成され、該一対の係合片のそれぞれに外壁パネルの物品の出し入れ方向と平面視で直交する方向の側端部を押える押え部材が係合され、該一対の係合片のそれぞれに係合された一対の押え部材の間に該一対の押え部材をその間隔が広がる方向の外方向へ付勢する溝係合部材が係合された構成とする。
【０００８】

以下の説明では便宜上、図１及び図２に示す矢印Ｆの方向を自動倉庫１の前方として、各構造体の前後・左右位置を説明するものとする。他の図面におけるその各構造体の前後・左右位置についても、これに倣うものとする。
【０００９】
まず、自動倉庫１について図１乃至図３を参照しながら説明する。
自動倉庫１には、多数の収納棚２５・２５・・・を有する前後一対の収納部２０・２０と、物品搬送装置３とが備えられている。
収納部２０・２０はそれぞれ、左右方向および上下方向に配列された多数の収納棚２５・２５・・・を備えている。この一対の収納部２０・２０は、キャビネット２内部に、後述する搬送台車３０のレール３８を挟んで対向配置される。各収納部２０の下部に設けられる水平板２９の下方には、粉塵吸込み用のファン９が設けられている。
【００１０】
この物品搬送装置３は、搬送体たる昇降台３４と、昇降台３４上の移載装置４とを備えている。該物品搬送装置３は、キャビネット２に備える受渡し口（図示せず）から移載装置４を用いて物品８を昇降台３４上に受け取った上で、空いている前記収納棚２５へ向けて昇降台３４を走行させ、移載装置４を用いて該収納棚２５へ物品を受け渡す。あるいは、収納棚２５に既に収納されている物品８を移載装置４を用いて昇降台３４上に受け取り、前記受渡し口へ向けて昇降台３４を走行させ、移載装置４を用いて該受渡し口へ物品８を受け渡す。
【００１１】
収納部２０・２０間にはレール３８・３８からなる軌道が敷設され、該レール３８・３８上に搬送台車３０が配置されている。搬送台車３０には走行車輪３１・３１・・・が設けられ、これらの走行車輪３１は前記レール３８・３８上に配置される。
以上の構成により搬送台車３０は、レール３８・３８により支持されながら該レール３８・３８に沿って走行可能とされる。
【００１２】
搬送台車３０上にはターンテーブル３５を介してマスト３６が立設され、ターンテーブル３５とともにマスト３６が回転駆動できるように構成している。前記昇降台３４はこのマスト３６に上下昇降駆動可能に取り付けられるものであり、昇降台３４上に物品８の移載装置４が備えられている。
【００１３】
前記移載装置４は伸縮自在のロボットハンドに構成されて、その先端部にフォーク４１を設け、該フォーク４１は、物品８を下方よりすくい上げることで物品８を支持するようにしている。フォーク４１の上面には突起が上方に突出される一方、物品８の底面には前記突起を挿入可能とする穴部が形成されて、この突起と穴部との係合によってフォーク４１上から物品８が落ちないように保持できるようにしている。この物品８を保持したフォーク４１は、収納棚２５を構成する左右一対の棚部材２５Ｌ・２５Ｒの間に挿入され、該物品８は該棚部材２５Ｌ・２５Ｒ上に載置される。
【００１４】
この棚部材２５Ｌ（又は２５Ｒ）は、プレス加工等により板状の部材を曲げ加工して成形されており、先端部２５ｂは斜上方へ屈曲され、一側部２５ｃは下方へ垂直に折り曲げられて、該側部２５ｃが支柱体２１に取り付けられる。
また、該棚部材２５Ｌ・２５Ｒの上面には位置決めピン１４・１４が凸設され、一方、収納棚２５に載置された物品８の底面には、フォーク４１の挿入方向に対する手前側両側部と、奥側中央部とで、正三角形の３頂点を形成するように３箇所に溝部が設けられており、該手前側両側部の溝部を、前記棚部材２５Ｌ・２５Ｒの上面の位置決めピン１４・１４に係合させて、物品８が収納棚２５に載置されている。また、このとき前記棚部材２５Ｌ・２５Ｒの先端部２５ｂ・２５ｂが物品８の手前側の端部に当接するように載置され、該棚部材２５Ｌ・２５Ｒの先端部２５ｂ・２５ｂにより物品８の回転が規制されている。
【００１５】
このように、前記各棚部材２５Ｌ・２５Ｒに設けられた位置決めピン１４・１４と、屈曲された先端部２５ｂ・２５ｂとで物品８の位置決めがなされ、本構成では、前記物品８の底面の奥側中央部に設けられた溝部と係合させるための位置決めピンが必要なく、部品点数を削減することができる。
また、本構成では、フォーク４１により物品８の底面の溝部を、棚部材２５Ｌ・２５Ｒ上の２箇所の位置決めピン１４・１４に挿入すればよいので、３箇所の位置決めピンに挿入するときよりも挿入作業が容易で、挿入ミスが減って、信頼性が向上する。
【００１６】
前記自動倉庫１が設置されるクリーンルームでは、無塵化を徹底するために、非接触給電方法が採用されている。収納部２０の下方の少なくとも何れか一方の水平板２９から給電線ホルダ５０が垂設され、その先端部に一対の給電線５１・５１が保持されている。この給電線５１・５１はレール３８・３８に沿って配置され、また、搬送台車３０には、該給電線５１・５１に発生する磁界から電流を得る受電装置５が配設されている。
【００１７】
受電装置５は、「Ｅ」字形状のコア５２を備え、該コア５２内部に前記一対の給電線５１・５１が挿入され、非接触の状態で配置されている。該コア５２にはピックアップコイル５３が巻回されており、給電線２に発生する磁界から電磁誘導により、該ピックアップコイル５３に誘導起電流が発生するのを利用して、受電装置５で電流を得るようにしている。
以上のようにして、受電装置５で取り出された電力を利用して、物品搬送装置３が備える搬送台車３０の駆動源や、昇降台３４の駆動源等が駆動される。
【００１８】
次に、本発明に係るキャビネット２の組付方法について説明する。
キャビネット２は、支柱体２１・２１・・・と、側壁ユニット２４と、該支柱体２１・２１間、及び該支柱体２１と該側壁ユニット２４とを接続する繋ぎ材２２・２２・・・とで枠組みが形成され、該支柱体２１・２１と該繋ぎ材２２・２２とで画設される面域に薄板状の外壁パネル２３が取り付けられている。前記棚部材２５Ｌ・２５Ｒは、図４に示すように、支柱体２１の左右両側部と、側壁ユニット２４の内側部とに、高さ方向に所定間隔を開けて取り付けられている。
【００１９】
図５乃至図８に示すように、支柱体２１は、アルミ等の押出成形により、棚部材２５Ｌ・２５Ｒ等が取り付けられる支柱基部２１Ｂ・２１Ｂと、その間に設けられた円筒体２１Ａとが一体的に成形されている。各支柱基部２１Ｂ・２１Ｂの両側面と、該両側面と直交する一方の支柱基部２１Ｂの外側面との５箇所に、断面視、「Ｔ」字型の取付溝２１ａ・２１ａ・２１ａ・２１ａ・２１ｂが形成され、他方の支柱基部２１Ｂの外側面には左右一対の係合片２１ｃ・２１ｃが凸設されている。該係合片２１ｃ・２１ｃの先端が互いに向き合うように折り曲げられ、この間に略「Ｔ」字型の係合溝２１ｄが形成されている。該取付溝２１ａ・２１ｂ及び係合溝２１ｃは支柱体２１の長手方向に沿って形成され、該取付溝２１ａ・２１ｂに係合具１１を係合させ、詳細は後述するが、該係合具１１を介して繋ぎ材２２を組み付けるようにしている。
【００２０】
また、前記取付溝２１ａの所定位置にナットプレートを係合させ、該ナットプレートの側方に前記棚部材２５Ｌ（又は２５Ｒ）の側部２５ｃに設けられた固定孔を配置して、該固定孔の外側方から固定ボルト１５を挿入し、該固定ボルト１５と、前記ナットプレートとを締結する。このように固定ボルト１５・１５とナットプレートとを介して、棚部材２５Ｌ（又は２５Ｒ）の側部２５ｃが、支柱体２１の一側面側の２つの取付溝２１ａ・２１ａに取り付けられる（図２参照）。こうして、支柱体２１の両側部に、所定間隔を開けて、多数の棚部材２５Ｌ・２５Ｒ・・・を取り付け、予めユニット化しておく。
【００２１】
なお、従来は、前後に並べられた一対の支柱に、上下方向に向け、多数の棚部材を架設して支柱ユニットを構成していたが、本実施例では、該一対の支柱の内、収納される物品８の出し入れ方向手前側に配置される一方の支柱を、出し入れ方向奥側の他方の支柱側に寄せて配置するとともに、両支柱を一体的に成形して支柱体２１を構成し、該支柱体２１に上下方向に向けて、多数の棚部材２５Ｌ・２５Ｒ・・・を取り付けて支柱ユニットを構成している。
物品８には両側面から把手部８ａ・８ａが突出するものもあり、本構成では、図３に示すように、把手部８ａ・８ａを有する物品８を収納する際、該把手部８ａ・８ａと該支柱体２１・２１とは干渉しない。このように支柱体２１・２１の左右間隔を拡幅することなく、物品８の収納効率の向上が図られている。
また、本構成の支柱ユニットは、多数の「凹」字状の収納棚が支柱から突出する従来の支柱ユニットに比べて搬送しやすく、搬送効率の向上が図られている。
さらに、本構成の支柱ユニットは、キャビネット２の設置予定地の外縁部分に立設されるため作業がしやすく、また、隣り合う支柱体２１・２１を繋ぎ材２２を介して容易に組み付けることができ、作業性の向上が図られている。
【００２２】
図９に示すように、前記係合具１１は、平面視、略「面」字のような形状で、方形状の本体１１ａから「Ｔ」字状の係合部１１ｂが突設され、該本体１１ａの中央に取付孔１１ｃが形成されている。該本体１１ａの一側面における取付孔１１ｃの縁部１１ｄはテーパ状に面取りが施されており、該一側面を上面にして、上方から固定ボルト１３を挿入しやすいようにしている。
【００２３】
図６、図１０及び図１１に示すように、前記繋ぎ材２２は、アルミ等の押出成形により、長手方向に中空部を有する形状に形成されている。該繋ぎ材２２の上下面は、一対の垂直面２２ｂ・２２ｂとにより連結され、該垂直面２２ｂ・２２ｂは該補強体２２ａにより連結されている。
そして、該垂直面２２ｂ・２２ｂと補強体２２ａの水平面２２ｃとで略「Ｈ」字状を形成し、該垂直面２２ｂ・２２ｂの下部には外方向へ突出する段部２２ｄ・２２ｄが形成されている。また、繋ぎ材２２の長手方向両側部には上方から中繰加工が施されて、該繋ぎ材２２の上面と、その直下方の水平面２２ｃとに挿入孔２２ｅ・２２ｆが形成されている。
【００２４】
さらに、繋ぎ材２２の上下面には長手方向に挿入溝２２ｇ・２２ｇが形成されている。この挿入溝２２ｇ・２２ｇは繋ぎ材２２の短手方向における一側端部に配置され、前記挿入孔２２ｅ・２２ｆは中央部からやや他側部寄りに配置されている。
【００２５】
次にこれらの部材の組付方法について説明する。
まず、図４（ａ）に示すように、キャビネット２の設置予定地に側壁ユニット２４を立設してフットアジャスタ６で床面に位置固定する。次に、図４（ｂ）に示すように、該側壁ユニット２４の側方に、棚部材２５Ｌ・２５Ｒ・・・を取り付けた支柱体２１を立設する。図５に示すように、この支柱体２１の下端部には、内方向へ向けて支持部材２６が取り付けられており、該支持部材２６の底面と、該支柱体２１の底面とにフットアジャスタ６・６が取り付けられる。
【００２６】
そして、床面に固定せずに立設される支柱体２１に繋ぎ材２２・２２・・・を取り付けていく。
この繋ぎ材２２の取り付け方であるが、図６、図７及び図９に示すように、まず、前記係合具１１を縦向きにして支柱体２１の取付溝２１ａに挿入した後、該係合具１１を９０°捻って横向きにし、取付孔１１ｃの縁部１１ｄを面取りした面を上に向けて、係合具１１の係合部１１ｂと取付溝２１ａとを係合させる。
【００２７】
次に、図１０及び図１１に示すように、被締結具たるナットプレート１２の両側部を、繋ぎ材２２の一側方から、補強体２２ａの段部２２ｄ・２２ｄに係合させて奥へ押し込み、この段部２２ｄ・２２ｄの間に収納されたナットプレート１２と該補強体２２ａの水平面２２ｃとの間に形成される挿入スペースに、前記係合具１１の本体１１ａを挿入する。
【００２８】
そして、このナットプレート１２の中央に形成される固定孔１２ｃと、係合具１１の取付孔１１ｃと、繋ぎ材２２の上面と水平面とに形成される挿入孔２２ｅ・２２ｆとの位置を、略一直線上に一致させて、締結具たる固定ボルト１３を該挿入孔２２ｅ・２２ｆから挿入し、該固定ボルト１３の下端部を該係合具１１の取付孔１１ｃと該ナットプレート１２の固定孔１２ｃとに連結する。より詳しく説明すると、係合具１１の取付孔１１は、挿入孔２２ｅ・２２ｆよりも若干支柱体２１側に位置するようになっている。この状態で、固定ボルト１３をナットプレート１２の固定孔１２ｃに螺合させると、取付孔１１ｃの縁部１１ｄに案内されて、係合具１１は支柱体２１と反対側に移動する。つまり、係合具１１の係合部１１ｂが支柱体２１の取付溝２１ａを引っ張った状態となり、支柱体２１に係合具１１が固定されるとともに、支柱体２１に繋ぎ材２２が固定される。
【００２９】
同様に、繋ぎ材２２の他側部は、側壁ユニット２４に形成された取付溝を介して取り付ける。こうして支柱体２１と側壁ユニット２４との上下方向に所定間隔を開けて繋ぎ材２２・２２・・・を介設し、該支柱体２１と該側壁ユニット２４とを連結した後、該支柱体２１の底面と、前記支持部材２６の底面とに取り付けたフットアジャスタ６・６を床面に固定する。
【００３０】
前記支柱体２１の円筒体２１Ａの挿入孔２１ｅはフットアジャスタ６のアジャスタボルト６１を挿入するために成形されている。即ち、図１２に示すように、ナット部材が嵌装固定される挿入孔２１ｅにアジャスタボルト６１を挿入固定し、コンクリートの床面に予め埋め込まれている固定ボルト６３を介してアジャスタボルト脚止金具６２を床面に固定し、支柱体２１を位置固定している。
なお、本実施の形態の自動倉庫１は、コンクリートの床面上に施工されているが、開孔が多数設けられたグレーチングなどの床面に施工してもよく、その場合、固定ボルト６３はグレーチングに固着される。
【００３１】
また同様に、前記の支柱体２１の側方に、繋ぎ材２２・２２・・・を介して、新たな支柱体２１を取り付けて床面に位置固定し、図５に示すように、支柱体２１・２１・・・を次々と並設していき、最外側方の支柱体２１の側方に側壁ユニット２４を取り付けて、キャビネット２の枠組みを構成する。
【００３２】
次に、図１に示すように、前記支柱体２１・２１と前記繋ぎ材２２・２２とで区画される面域に、可撓性を有する前記薄板状の外壁パネル２３を嵌め込み、押え部材１８・１８と溝係合部材１９とを介して取り付けていく。
【００３３】
前記押え部材１８と、溝係合部材１９とは外壁パネル２３の一片と略同長さの部材で、平面視は、図１３（ａ）に示すように形成される。押え部材１８は略「Ｆ」字を寝かせた形状で、前記支柱体２１の外側面の係合片２１ｃと係合する係合部１８ａと、該係合部１８ａと平行に突出する押止部１８ｂと、該係合部１８ａと直交する方向に突出する被係止部１８ｃとを有し、該係合部１８ａの先端は該押止部１８ｂ方向に折り曲げられ鉤状に形成されている。溝係合部材１９は、左右に係止部１９ａ・１９ａを有しており、略「コ」字を寝かせた形状に形成され、弾性変形可能に構成されている。
【００３４】
次に、これら押え部材１８・１８と、溝係合部材１９とを用いての、外壁パネル２３の取付方法を説明する。
まず、外壁パネル２３の下端を、下側の繋ぎ材２２の上面に形成される挿入溝２２ｇ（図１０参照）に挿入し、該外壁パネル２３を撓ませながらその上端を、上側の繋ぎ材２２の挿入溝２２ｇに挿入する。
【００３５】
そして、図１３（ｂ）に示すように、前記支柱体２１の外側面の一対の係合片２１ｃ・２１ｃにそれぞれ押え部材１８・１８の係合部１８ａ・１８ａを係合させて、一方の押え部材１８の押止部１８ｂにより本面域の外壁パネル２３の側端部を押え、他方の押え部材１８の押止部１８ｂにより隣の面域の外壁パネル２３の側端部を押えるように構成している。
なお、前記押え部材１８の押止部１８ｂと外壁パネル２３の側端部との間にスペーサを介設し、該スペーサを介して外壁パネル２３を固定してもよい。
【００３６】
そして、図１３（ｃ）に示すように、該一対の係合片２１ｃ・２１ｃに係合する押え部材１８・１８の被係止部１８ｃ・１８ｃの間に、溝係合部材１９を挿入し、係合させる。
この場合、押え部材１８・１８間の寸法よりも、溝係合部材１９の幅寸法の方が若干大きく形成されているため、被係止部１８ｃ・１８ｃ間に挿入された溝係合部材１９は弾性変形して、該被係止部１８ｃ・１８ｃを左右外側方向へ付勢することとなる。また、係止部１９ａ・１９ａは、先端側の間隔が根元側の間隔よりも小さく形成されているので、被係止部１８ｃ・１８ｃ間に挿入する際に、挿入しやすくなっている。
【００３７】
両者が係合した後は、前述のように、弾性を有する溝係合部材１９は両側方の押え部材１８・１８を外方向へ付勢するため、押え部材１８・１８は係合片２１ｃ・２１ｃから容易に外れない。
このようにして支柱体２１・２１と繋ぎ材２２・２２とで区画される面域に、特別な工具を使うことなく、簡単に外壁パネル２３をしっかりと取り付けることができる。
【００３８】
一方、外壁パネル２３を取り外すときには、押え部材１８・１８の間に係合する溝係合部材１９の上端、又は下端を指で引っ掛けて取り外せば、該押え部材１８・１８は容易に外れ、そして、該外壁パネル２３の両側部を持って、その上下端を上下の繋ぎ材２２の挿入溝２２ｇ・２２ｇから抜き出してやればよい。このように取り外しも簡単に行うことができ、移載装置４が故障したときなど、作業者が該外壁パネル２３を取り外して、自動倉庫１の外側から、収納棚２５上の物品８を直接取り出すことができる。
【００３９】
【発明の効果】
本発明は、以上のように構成したので、以下のような効果を奏する。
自動倉庫に収納される物品には物品の出し入れ方向と平面視で直交する方向の両側面から把手部が突出するものもあり、請求項１に記載の発明では、第１及び第２の支柱の物品の出し入れ方向と平面視で直交する方向の間隔を拡幅することなく、把手部を有する物品を収納する際に、該把手部と該第１及び第２の支柱とは干渉しない構成とすることができ、物品の収納効率の向上を図ることができる。
【００４０】
そして、請求項２に記載の発明では、前記第１の支柱と前記第２の支柱とは一体形成され、該第１の支柱と該第２の支柱との間に、床面に対して位置決めする位置決め部材の挿入孔を形成したことで、床面に対して位置決めする位置決め部材の挿入孔を別途形成する必要がなく、部品点数が減ってコスト削減を図ることができる。
【００４１】
また、請求項３に記載の発明では、第１の支柱の背面の一対の係合片のそれぞれに係合された一対の押え部材の間に溝係合部材を挿入して係合した後は、溝係合部材は物品の出し入れ方向と平面視で直交する方向の両側方の押え部材をその間隔が広がる方向の外方向へ付勢するため、押え部材は係合片から容易には外れず、第１の支柱と繋ぎ材とで区画される面域に、特別な工具を使うことなく、簡単に外壁パネルをしっかりと取り付けることができる。
