Description

【0001】
【発明の属する技術分野】
本発明は、鋼管、形鋼、棒鋼等(以下、単に製品という)が載置される一対の棚部材が水平方向に開閉(出入り)して、製品の収納、取り出しを行う収納棚装置に関する。
【0002】
【従来の技術】
従来、鋼管、棒鋼等の長尺材の製品を収納したり、取出したりするために、所定の水平間隔で設けられた対となる支持柱の一方の支持柱には、複数段上下方向に配置された棚部材が垂直方向又は水平方向に回動可能に設けられ、他方の支持柱には、棚部材の先端部を支持する受け部が複数段上下方向に設けられた収納棚装置が使用されている。この収納棚装置においては、複数の製品を複数回に分けて複数段の棚部材に載せることができ、特に、棚部材が水平方向に回動する場合には、棚部材の上下方向の取付けピッチを小さくでき、収納効率を高くすることができる。なお、棚部材は、エアシリンダー等を備えた開閉手段を介して水平回動するようになっている(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開平8−290810号公報
【0004】
【発明が解決しようとする課題】
しかしながら、前記従来の収納棚装置においては、未だ解決すべき以下のような問題があった。
製品が載置されていない無負荷の棚部材を水平回動して開閉する時、棚部材の先端部と接触する受け部との摩擦係数が大きく、このため、エアシリンダー等の出力(動力)を大きくする必要があり、狭いスペースに、このエアシリンダーを収めることが困難であり、収めるためには収納効率が小さくなるという問題があった。
また、棚部材と受け部との摩擦係数を小さくするために、例えば、棚部材の先端部又は受け部に車輪等の摩擦力低減機構を設けた場合には、棚部材上に製品を載置した際の安定性がよくなかった。
【0005】
本発明はこのような事情に鑑みてなされたもので、容量が小さくコンパクトな開閉手段を使用でき、しかも、製品を載置した場合にも安定性が良好な収納棚装置を提供することを目的とする。
【0006】
【課題を解決するための手段】
前記目的に沿う本発明に係る収納棚装置は、上下方向に間隔を開けて複数段に配置され、水平方向に開閉する一対の棚部材の基部がそれぞれ回動自在に取付けられた対となる前後の棚部材支持柱と、棚部材支持柱と対となって、一対の棚部材の先端部が当接する受け部を備えた前後の棚部材受け柱とを有し、複数段の一対の棚部材上に製品を載置して収納する収納棚装置であって、
一対の棚部材はそれぞれ、開閉手段に連結され棚部材支持柱に垂直に設けられた垂直ピン回りに水平方向に回動する水平回動部と、水平回動部に水平に設けられた水平ピン回りに垂直方向に回動し製品が載置される垂直回動部と、垂直回動部を水平ピン回りに上側に付勢する付勢部材とを備え、
一対の棚部材の開位置において、一対の棚部材上に製品が載置されていない場合には、棚部材の垂直回動部の先端部は棚部材受け柱の受け部と隙間を有し、一方、一対の棚部材上に製品が載置される場合には、棚部材の垂直回動部の先端部は棚部材受け柱の受け部に当接する。
これによって、一対の棚部材上に製品が載置されていない場合には、棚部材の垂直回動部の先端部は棚部材受け柱の受け部と隙間を有しているので、一対の棚部材を小さな動力で回動することができ、また、一対の棚部材上に製品が載置される場合には、棚部材の垂直回動部の先端部は棚部材受け柱の受け部に当接するので、製品を安定して収納することができる。
【0007】
本発明に係る収納棚装置において、開閉手段の駆動源はエアシリンダーであって、エア回路には、一対の棚部材の開閉用でセンターブロック可能な3位置切換弁と、棚部材の開、閉位置をそれぞれ検出して作動する一対の2位置切換弁とを設け、
棚部材の開、閉位置にて、2位置切換弁を介してエアをエアシリンダーに補給することにより、一対の棚部材が開、閉位置をそれぞれ維持できるように構成することもできる。
これによって、3位置切換弁の使用により、操作ミスを解消することができると共に、一対の2位置切換弁の使用により、一対の棚部材を常に開、閉位置に保持することができる。
【0008】
本発明に係る収納棚装置において、付勢部材はコイルバネであってもよい。
これによって、棚部材の垂直回動部の先端部と棚部材受け柱の受け部との隙間を大きく取ることができる。
【0009】
本発明に係る収納棚装置において、前後の棚部材支持柱を左右方向に複数列設け、しかも、左右方向の最端の棚部材支持柱を除く棚部材支持柱には、受け部を設けることもできる。
これによって、複数列に大量の製品を収納することができる。
【0010】
【発明の実施の形態】
続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。
ここに、図1は本発明の一実施の形態に係る収納棚装置の正面図、図2は同収納棚装置の平面図、図3は同収納棚装置の要部正断面図、図4は同収納棚装置の要部平面図、図5は図3のa部拡大図、図6は図4の矢視A−A断面図、図7はエア回路を示す説明図、図8は棚部材の開、閉位置と2位置切換弁の取付位置との関係を示す説明図である。
【0011】
図1〜図4に示すように、本発明の一実施の形態に係る収納棚装置10は、上下方向に間隔Kを開けて2段に配置され、しかも、左右方向に6列配置された水平方向に開閉する一対の棚部材11、12を有しており、一対の棚部材11、12が開位置にある場合には、一対の棚部材11、12上に製品の一例である6角パイプPを3(本/段)×2段=6本載置して収納でき、一方、一対の棚部材11、12が閉位置(図2中、二点鎖線で示す)にある場合には、一対の棚部材11、12の下方の6角パイプPを取り出したり、又は一対の棚部材11、12の下方に6角パイプPを載置することができるように構成されている。
【0012】
また、収納棚装置10は、12組の棚部材11、12と、一対の棚部材11、12の基部がそれぞれ回動自在に取付けられた対となる前後の棚部材支持柱13、14(1列目〜5列目)及び前後の棚部材支持柱15、16(6列目)と、1列目の棚部材支持柱13、14と対となって、一対の棚部材11、12の先端部17が当接する受け部18を備えた前後の棚部材受け柱19、20(1列目)とを有し、前後の棚部材支持柱13、14(1列目〜5列目)は、2列目〜5列目の前後の棚部材支持柱13、14及び6列目の前後の棚部材支持柱15、16とそれぞれ対となって、一対の棚部材11、12の先端部17が当接する受け部18aを備えている。
【0013】
以下、これらについて詳しく説明する。なお、同一の構成要素については、同一の符号を付して詳しい説明を省略する。また、一対の棚部材11、12に載置された6角パイプPの長手方向を前後方向、前後方向に直交する方向を左右方向、前後方向及び左右方向に直交する方向を上下方向と定義する。
【0014】
図1〜図4に示すように、棚部材支持柱13〜16及び棚部材受け柱19、20はそれぞれ、同じサイズのH形鋼からなっており、棚部材支持柱13、14の下端部間、棚部材支持柱15、16の下端部間及び棚部材受け柱19、20の下端部間はそれぞれ、床面Fに固定されて前後方向に配置された連結部材21を介して連結されている。連結部材21は、図1及び図2に示すように、両端部に設けられた短尺のH形鋼からなる端部材22、23と、端部材22、23の内側同士を連結する中間部材24とを備えている。
【0015】
また、左右方向に隣り合う棚部材受け柱19、棚部材支持柱13、15及び棚部材受け柱20、棚部材支持柱14、16の下端部間はそれぞれ、床面Fに固定されて左右方向に配置されたH形鋼からなる連結部材25を介して連結されている。図1に示すように、各列の下段の棚部材11、12の下方にはそれぞれ、6角パイプPが3(本/段)×3段=9本、前後方向に対となる連結部材25に載置されて収納できるようになっている。
次に、1列目の上段の一対の棚部材11、12について説明するが、棚部材12は棚部材11の勝手違いであって、実質的に同じであるので、以降では、棚部材11についてのみ説明する。
【0016】
図3〜図6に示すように、棚部材支持柱13のH形鋼のウェブ26の内側面には垂直方向に間隔を開けて山形鋼からなるピン取付ブラケット27、28が設けられており、棚部材11は、ピン取付ブラケット27、28に両端部が支持された垂直ピン29回りに水平方向に回動する水平回動部30と、水平回動部30に水平に設けられた水平ピン31回りに垂直方向に回動し、6角パイプPが載置される垂直回動部32と、垂直回動部32の基部に一体的に直交して設けられた回動アーム33と、回動アーム33を水平ピン31回りに上側に付勢する付勢部材の一例であるコイルバネ34とを備えている。垂直ピン29の上、下端部はそれぞれ、ピン取付ブラケット27、28に設けられた短尺パイプ状のピン受け27a、28aに保持されている。
【0017】
水平回動部30は、断面円形の垂直ピン29の中間部を覆うパイプ状の摺動部35と、摺動部35の上部に設けられ、垂直回動部32の基部即ち、回動アーム33の上端部を回動可能に支持する水平ピン31を取付けるための取付ブラケット36と、回動アーム33の下端部に略水平に設けられたコップ状のバネ受け座37に一端がセットされたコイルバネ34の他端を受けるバネ受け座38とを有している。バネ受け座38は、バネ受け座37に対向して設けられており、コイルバネ34の中心部に挿通してコイルバネ34の伸縮をガイドする断面円形の突起部39と、突起部39の基端部に一体的に設けられ、コイルバネ34の他端を受けると共に、6角パイプPが棚部材11に載置された際にバネ受け座37の内側をガイド可能な断面円形の受け座本体40とを備えている。
【0018】
なお、図3及び図5は、棚部材11上に6角パイプPが載置されていない状態を表しており、コイルバネ34の付勢力により、回動アーム33を介して棚部材11の先端部17は棚部材受け柱19に設けられた受け部18に当接せず、隙間を有している。棚部材11上に6角パイプPが載置されると、コイルバネ34の付勢力に打ち勝って、棚部材11の垂直回動部32の先端部17は棚部材受け柱19の受け部18に当接することになる。
【0019】
摺動部35とピン受け27a、28aとは外径が同じサイズであり、内径は摺動部35の方が若干大きいものを使用しており、摺動部35の上、下端面とピン受け27aの下端面、ピン受け28aの上端面間(約2mm)には、リング板状の軸受27b、28bが嵌装されていると共に、垂直ピン29の外周面と摺動部35の内周面との間には、薄肉のスリーブ状の軸受29aが嵌装されている。また、水平ピン31と回動アーム33との間にも、軸受29aと同様のスリーブ状の軸受31aが嵌装されている。軸受27b、28b、軸受29a及び軸受31aは摩擦係数を低減するために、例えば、テフロン(登録商標)製としている。
ピン取付ブラケット27、28はそれぞれ、4箇所に形成された取付ボルト孔41を介して棚部材支持柱13のH形鋼のウェブ26にねじ締結されている。
【0020】
図3〜図5に示すように、水平回動部30の摺動部35の外周には、平面視してL字状のアーム42の一端部が固定されている。アーム42の他端部は、棚部材支持柱13のH形鋼のウェブ26に設けられた対となる軸受43にロッド側がトラニオン支持された駆動源の一例であるエアシリンダー44のロッド先端に設けられた二股形状の接続金具45に、連結ピン46を介して連結されている。連結ピン46とアーム42との間にも、軸受31aと同様に、摩擦係数を低減するために、例えば、テフロン(登録商標)製のスリーブ状の軸受42aが嵌装されている。ここで、エアシリンダー44、接続金具45及びアーム42等により開閉手段が構成されることになる。かかる構成によって、エアをエアシリンダー44に供給して駆動することにより、アーム42を介して水平回動部30を垂直ピン29回りに、略90°回動することができる。
【0021】
図3及び図4に示すように、棚部材受け柱19の受け部18は短尺の溝形鋼からなっており、棚部材受け柱19のH形鋼のフランジに水平に固定されている。受け部18の上面には、軟質材の一例である樹脂製で矩形板状のライナー47が取付けられている。また、棚部材11の垂直回動部32の6角パイプPが載置される部分の上面には、軟質材の一例である樹脂製で矩形板状のライナー32aが、ねじ締結により取付けられている。
【0022】
棚部材支持柱13にも、棚部材受け柱19の受け部18と略同様の位置に、受け部18より長尺の溝形鋼からなる受け部18aが、H形鋼のフランジに水平に固定されている。棚部材受け柱19、棚部材支持柱13(棚部材支持柱15は棚部材受け柱19と勝手違い)にも、6角パイプPの載置及び取り出しの際に、6角パイプPに疵を付けないように、軟質材の一例である樹脂製で矩形板状のライナー19a(頂部)、19b(対向する側部)が、ねじ締結により取付けられている。
【0023】
受け部18の先端部及び受け部18aの中間位置にはそれぞれ、棚部材11の水平方向のずれを防止するためのずれ止め片48が設けられている。さらに、受け部18aの先端部には、棚部材11の閉位置での回動を停止するための、ストッパー49が取付けられている。なお、図5中の符号50はエアシリンダー44を取付けるために棚部材支持柱13のウェブ26に形成された矩形状の切り欠き孔を表している。また、図6中の符号51、52は、ピン取付ブラケット27、28に取付けたピン受け27a、28aを強固に固定するための補強リブを表している。
【0024】
図7に本発明の一実施の形態に係る収納棚装置10のエア回路10aを示すが、説明を簡略にするため、模式的に表している。
エア回路10aにおいて、各列及び各段の一対の棚部材11、12毎に、電磁弁からなる3位置切換弁53が設けられており、1つの3位置切換弁53によって、棚部材11、12の開操作及び棚部材11、12の閉操作を行うと共に、3位置切換弁53の切換の中立位置で全ポートが閉じられて(センターブロックされて)、棚部材11、12を棚部材11、12の開、閉位置(停止位置)で保持するように構成されている。
【0025】
さらに、図8にも詳細を示すように、棚部材11、12の開、閉位置で、何らかの理由、例えば、長時間の保持によるエアシリンダー44からのエアリーク、また、エアシリンダー44、3位置切換弁53及びエア配管等の製作、組立不良によるエアリーク、さらに、棚部材11、12の振動等によって、一対の棚部材11、12が開、閉位置から所定の距離で離れると、6角パイプPを収納及び取り出し作業ができなくなるので、棚部材11、12が常時、開、閉位置を保持できるように構成されている。
【0026】
図7及び図8に示すように、一対の棚部材11、12の棚部材11(棚部材12でも構わない)には、棚部材11の開、閉位置をそれぞれ機械的に検出して作動する一対の2位置切換弁54、55が設けられており、棚部材11、12の開、閉位置にて、2位置切換弁54、55を介して対となる2つのエアシリンダー44にエアを常時補給することにより、一対の棚部材11、12の開、閉位置での停止を維持できるように構成されている。
【0027】
図8に示すように、開、閉位置にある棚部材11をそれぞれ検出する2位置切換弁54、55が、ピン取付ブラケット27に設けられた板状のブラケット56に取付けられている。2位置切換弁54、55にはそれぞれ、流路切換用のスライドスプールを作動するためのレバー57、58が設けられており、棚部材11の基部(回動アーム33)がレバー57、58に当接することによって、流路を閉から開に切り換えることができる。
【0028】
図7に示すように、エア回路10aにおいて、2位置切換弁54、55は3位置切換弁53より上流側に設けられており、3位置切換弁53の操作に無関係に作動するように構成されている。しかも、一対の2位置切換弁54、55はエア入口同士が連通されており、かつ、各列の上、下段に対して直列に設けられている。
かかる構成によって、図8に示すように、例えば、棚部材11が開位置にある場合には、3位置切換弁53は中立位置にあって3位置切換弁53からのエアは遮断されており、一方、2位置切換弁54のレバー57が回動アーム33に当接して2位置切換弁54の流路が開となっているので、2位置切換弁54を介して一対のエアシリンダー44にエアが常時補給されているため、棚部材11、12を開位置に保持することができる。
【0029】
また、図8に示す棚部材11が閉位置にある場合も、2位置切換弁55が2位置切換弁54と同様に作動し、棚部材11、12を閉位置に保持することができる。棚部材11、12が開、閉位置以外の位置(レバー57、58の作動が及ばない範囲)では、2位置切換弁54、55の流路が閉となって、エアシリンダー44へのエアの補給は遮断されている。なお、図7中の符号59はエアコンプレッサーを、符号60はエアフィルター付きレギュレーターを、符号61、62はスピードコントローラーを表している。スピードコントローラー61は、補給用のエアを少量供給するもので、また、スピードコントローラー62は棚部材11、12の回動速度を制御するものである。
【0030】
なお、3位置切換弁53を用いて、切換弁の中立位置(ニュートラル)で棚部材11、12を開、閉位置に保持した理由は次の通りである。棚部材11、12が開状態で6角パイプPが棚部材11、12に載置されている時、誤って棚部材11、12を閉状態に操作(誤操作)しようとすると、棚部材11、12は6角パイプPの重量により動作できない。しかし、もし、2位置切換弁を使用した場合には、エアシリンダー44に作用するエアー圧は、駆動側は最大で、かつ制動側はゼロで保持されることになるので、この状態で、6角パイプPを吊り上げると、棚部材11、12の動作は暴走状態となる。この暴走状態を防止するために、センターブロック可能な3位置切換弁53を設ける。
しかし、3位置切換弁53を設けた場合、上述のように、シール等のエアーリークにより、棚部材11、12の全開、全閉位置を保持することが困難となることがあるため、スピードコントローラー61を介して、2位置切換弁54、55からリーク分のみエアーを補給するようにしている。従って、2位置切換弁54、55からのエアー補給量は、3位置切換弁53からの供給量と比べて無視できるくらい少量とする必要があり、もし、多量に補給すると、回路上の矛盾のため動作不良を起こすことになる。
【0031】
次いで、本発明の一実施の形態に係る収納棚装置10の使用方法及び作用について、図を参照しながら説明する。なお、6角パイプPが収納されていない収納棚装置10に、6角パイプPを収納する場合について説明する。
(1)図1及び図2に示すように、収納したい1列目(2〜6列目も同じ)の上下2段の一対の棚部材11、12を閉位置とする。
【0032】
(2)長さが前後方向に配置され、水平方向に並べて配置された3本の6角パイプPをリフティングマグネット吊り具により吊って、連結部材25上に載置する。さらに、リフティングマグネット吊り具により、同じ操作を2回繰り返して、連結部材25上に載置された3本の6角パイプP上に、3本の6角パイプPを2段載置して、連結部材25上に、合計3本の6角パイプPを3段載置する。
(3)下段用の3位置切換弁53を開操作して、下段用の一対のシリンダー44を駆動し、下段の一対の棚部材11、12を閉位置から開位置に回動する。この際、棚部材11、12は無負荷であるので、棚部材11、12の開位置では、棚部材11、12の先端部17は棚部材受け柱19の受け部18と隙間を有している。
【0033】
(4)下段の一対の棚部材11、12上に、リフティングマグネット吊り具により、3本の6角パイプPを1段載置すると、棚部材11、12の先端部17は棚部材受け柱19の受け部18に当接する。さらに、載置された3本の6角パイプP上にもう1段の3本の6角パイプPを載置して、棚部材11、12上に3本の6角パイプPを2段載置する。
【0034】
(5)上段用の3位置切換弁53を開操作して、上段用の一対のシリンダー44を駆動し、上段の一対の棚部材11、12を閉位置から開位置に回動する。この際、棚部材11、12は無負荷であるので、棚部材11、12の開位置では、棚部材11、12の先端部17は棚部材受け柱19の受け部18と隙間を有している。
(6)上段の一対の棚部材11、12上に、リフティングマグネット吊り具により、3本の6角パイプPを1段載置すると、棚部材11、12の先端部17は棚部材受け柱19の受け部18に当接する。さらに、載置された3本の6角パイプP上にもう1段の3本の6角パイプPを載置して、棚部材11、12上に3本の6角パイプPを2段載置する。
【0035】
なお、前記(6)の状態に収納された6角パイプPを取り出す場合は、前記(6)から順次、前記(1)まで逆の操作を行う。
また、一対の棚部材11、12の閉位置や無負荷時の開位置において、上述したように、2位置切換弁54、55の作動により、常に、一対の棚部材11、12は開、閉位置を保持することができるので、収納及び取り出し作業は安全に行える。
【0036】
本発明は前記した実施の形態に限定されるものではなく、本発明の要旨を変更しない範囲での変更は可能であり、例えば、前記したそれぞれの実施の形態や変形例の一部又は全部を組み合わせて本発明の収納棚装置を構成する場合も本発明の権利範囲に含まれる。
前記実施の形態においては、製品として6角パイプPを使用したが、これに限定されず、状況に応じて、その他の棒状物を使用することもできる。
【0037】
前後の棚部材支持柱を左右方向に6列に、かつ、1列当たり一対の棚部材11、12を上下2段に設けたが、これに限定されず、必要に応じて、列数については、2〜5列又は7列以上にしたり、また、段数については、3段以上設けることもできる。
棚部材11、12の開閉手段の駆動源をエアシリンダー44としたが、これに限定されず、必要に応じて、電動シリンダー又は油圧シリンダーを用いても構わない。
棚部材11、12を別々のエアシリンダー44により駆動したが、これに限定されず、必要に応じて、一つのエアシリンダーで同期駆動する構造とすることもできる。
【0038】
棚部材11、12の垂直回動部32を上方に付勢する付勢部材としてコイルバネ34を用いたが、これに限定されず、必要に応じて、その他の弾性部材(ゴム等)を使用することもできる。
棚部材11、12の垂直回動部32の先端部17が当接する棚部材受け柱19の受け部18に、軟質材として樹脂製のライナー47を用いたが、これに限定されず、状況に応じて、その他の軟質材(ゴム等)を用いても構わない。
【0039】
【発明の効果】
請求項1〜4記載の収納棚装置においては、一対の棚部材上に製品が載置されていない場合に、棚部材の垂直回動部の先端部は棚部材受け柱の受け部と隙間を有しているので、一対の棚部材を小さな動力で回動することができ、この結果、棚部材の開閉手段をコンパクトに構成することができるため、収納効率が向上する。また、一対の棚部材上に製品が載置される場合に、棚部材の垂直回動部の先端部は棚部材受け柱の受け部に当接するので、製品を安定して収納することができ、この結果、安定した段積み作業ができる。
特に、請求項2記載の収納棚装置においては、3位置切換弁の使用により、操作ミスを解消することができると共に、一対の2位置切換弁の使用により、一対の棚部材を常に開、閉位置に保持することができるので、段積み作業の安全性が向上する。
【0040】
請求項3記載の収納棚装置においては、棚部材の垂直回動部の先端部と棚部材受け柱の受け部との隙間を大きく取ることができるので、棚部材の開閉動作がより安定する。
請求項4記載の収納棚装置においては、複数列に大量の製品を収納することができるので、収納量が増加する。

[0024]
FIG. 7 shows an air circuit 10a of the storage shelf device 10 according to one embodiment of the present invention, but is schematically shown in order to simplify the description.
In the air circuit 10 a, a three-position switching valve 53 including an electromagnetic valve is provided for each pair of shelf members 11, 12 in each row and each stage, and the shelf members 11, 12 are provided by one three-position switching valve 53. Are opened and the shelf members 11 and 12 are closed, and all the ports are closed (center-blocked) at the neutral position of the switching of the three-position switching valve 53, so that the shelf members 11 and 12 are connected to the shelf members 11 and 12. It is comprised so that it may hold | maintain in 12 open and closed positions (stop position).
[0025]
Further, as shown in detail in FIG. 8, when the shelf members 11 and 12 are in the open and closed positions, for some reason, for example, air leak from the air cylinder 44 due to long-time holding, and the air cylinder 44 and three-position switching. When the pair of shelf members 11 and 12 are opened and separated from the closed position by a predetermined distance due to the production of the valve 53 and the air piping and the like, air leak due to assembly failure, and vibration of the shelf members 11 and 12, the hexagonal pipe P Thus, the shelf members 11 and 12 can be always held in the open and closed positions.
[0026]
As shown in FIGS. 7 and 8, the shelf member 11 of the pair of shelf members 11 and 12 (which may be the shelf member 12) operates by mechanically detecting the open and closed positions of the shelf member 11. A pair of two-position switching valves 54 and 55 are provided, and air is always supplied to the two air cylinders 44 that are paired via the two-position switching valves 54 and 55 when the shelf members 11 and 12 are opened and closed. By replenishing, the pair of shelf members 11 and 12 are configured to be able to maintain the stop at the open and closed positions.
[0027]
As shown in FIG. 8, two-position switching valves 54 and 55 that detect the shelf member 11 in the open and closed positions are attached to a plate-like bracket 56 provided on the pin attachment bracket 27. The two-position switching valves 54 and 55 are respectively provided with levers 57 and 58 for operating the slide spool for switching the flow path, and the base (rotating arm 33) of the shelf member 11 is connected to the levers 57 and 58. By contacting, the flow path can be switched from closed to open.
[0028]
As shown in FIG. 7, in the air circuit 10 a, the two-position switching valves 54 and 55 are provided upstream from the three-position switching valve 53 and are configured to operate regardless of the operation of the three-position switching valve 53. ing. Moreover, the air inlets of the pair of two-position switching valves 54 and 55 communicate with each other, and are provided in series with respect to the upper and lower stages of each row.
With this configuration, as shown in FIG. 8, for example, when the shelf member 11 is in the open position, the three-position switching valve 53 is in the neutral position, and the air from the three-position switching valve 53 is shut off. On the other hand, since the lever 57 of the two-position switching valve 54 abuts against the rotating arm 33 and the flow path of the two-position switching valve 54 is open, the air flows to the pair of air cylinders 44 via the two-position switching valve 54. Is constantly replenished, the shelf members 11 and 12 can be held in the open position.
[0029]
Further, even when the shelf member 11 shown in FIG. 8 is in the closed position, the 2-position switching valve 55 operates in the same manner as the 2-position switching valve 54, and the shelf members 11 and 12 can be held in the closed position. When the shelf members 11 and 12 are in positions other than the open and closed positions (the range in which the levers 57 and 58 are not actuated), the flow paths of the two-position switching valves 54 and 55 are closed, and the air to the air cylinder 44 is closed. Supply is cut off. In FIG. 7, reference numeral 59 represents an air compressor, reference numeral 60 represents a regulator with an air filter, and reference numerals 61 and 62 represent speed controllers. The speed controller 61 supplies a small amount of replenishment air, and the speed controller 62 controls the rotation speed of the shelf members 11 and 12.
[0030]
The reason why the shelf members 11 and 12 are opened and closed at the neutral position (neutral) of the switching valve using the three-position switching valve 53 is as follows. When the shelf members 11 and 12 are open and the hexagonal pipe P is placed on the shelf members 11 and 12, if the shelf members 11 and 12 are erroneously operated (erroneous operation), 12 cannot operate due to the weight of the hexagonal pipe P. However, if a two-position switching valve is used, the air pressure acting on the air cylinder 44 is maintained at a maximum on the driving side and zero on the braking side. When the square pipe P is lifted, the operation of the shelf members 11 and 12 becomes a runaway state. In order to prevent this runaway state, a three-position switching valve 53 that can be center-blocked is provided.
However, when the three-position switching valve 53 is provided, as described above, it may be difficult to maintain the fully open and fully closed positions of the shelf members 11 and 12 due to air leaks such as seals. The air is replenished from the two-position switching valves 54 and 55 only through the leak via the 61. Therefore, the air supply amount from the two-position switching valves 54 and 55 needs to be negligibly small compared with the supply amount from the three-position switching valve 53. Therefore, it will cause malfunction.
[0031]
Next, the usage method and operation of the storage shelf device 10 according to the embodiment of the present invention will be described with reference to the drawings.
