Description

【０００１】
【発明の属する技術分野】
本発明は板状体の搬送用パッドに関し、特に電子機器に使用される液晶基板、液晶モジュールの導光板、プリント配線基板等の板状体を収納して搬送したり、また一次的に保管したりするのに使用するものである。
【０００２】
【従来の技術】
電子機器に使用される例えば液晶モジュールの導光板は、例えば透明度が高いアクリル樹脂を使用しているので、ごみ、傷、汚れを極度に嫌うため、全ての平面に梱包材が接触して梱包され、搬送、保管することはできなかった。
そして、導光板等の板状体の搬送方法として大きさ毎の撓み性を考慮して例えば１〜４インチのサイズの導光板と、５インチ以上のサイズの導光板に分けて搬送を行う等、搬送方法が異なっていた。
例えば撓み性が小さな１〜４インチの大きさの小さなサイズに形成される導光板は、熱可塑性の合成樹脂シートを真空成形等の熱成形をすることにより全体形状が略皿形に成形されるトレー内に横置きされて搬送されたり、また合成樹脂発泡材を用いて成形される箱等の梱包品を用いて搬送が行われていた。
また、５インチ以上のサイズの大きさの大きなサイズに形成される導光板は、撓み性が大きいので、保護フィルムを導光板の表面に貼着して重合させるようにして搬送を行うか、または薄い緩衝材を板状体相互間に挟むようにして重ね合わせることにより搬送が行われていた。
【０００３】
このように板状体相互間に緩衝材を挟んで重ね合わせてから搬送を行う方法が従来あった。
すなわち、梱包物としての板状体を搬送するのに、外周が板状体の外周よりも大きくかつ内周が板状体より一回り小さいロ字形の低発泡体からなる緩衝材と板状体とを順に複数枚重ね、これらをゴム輪またはテープで固定する方法である。ところが、この従来方法はロ字形の板状体を打ち抜き加工する場合に、粉が発生し、そのために板状体と緩衝材とを重ね合わせる複数枚の集合体を固定する際に、或いは搬送時の振動等により緩衝材と板状体が摺擦し合い、板状体に組み込んだ電子部品を広範囲に損傷させるという問題があった。
【０００４】
上記問題点を解決する従来技術として、例えば特開平５−３１９４５６号公報の発明がある。この発明は図１６ないし図１８に示すように対をなす当て板ａ,ｂと、ヒンジ部cとを有し集合体dに対する四隅に配置される４つのコーナパッドであって、対をなす当て板ａ,ｂは、梱包物としての板状体ｆのコーナを挟み込む隣接した端部にそれぞれあてがう発泡樹脂からなる平板形状をなし、コーナの隣接した端部がなす角度に組み合わせて用いるものであり、前記対をなす当て板ａ,ｂは、溝ｇを有し、溝ｇは平板状の板状体ｆのコーナと向き合う当て板ａ,ｂの内面に所望のピッチで平行に設けられ、板状体ｆの端縁を嵌合、保持するものである。
【０００５】
【発明が解決しようとする課題】
しかしながら、図１６ないし図１８に示すような前記従来の発明は、板状体ｆと緩衝材ｈとを重ね合わせる複数枚の集合体ｄに対する四隅に配置される４つのコーナパッドは、４個とも、ヒンジ部ｃで係合された対をなす当て板ａ,ｂの両側に側壁を設けていないので、落下したりぶつかったりすると、梱包物としての板状体fに圧縮しようとする力が直接かかるとともにヒンジ部ｃを閉じようとする力が直接かかる。そのため、電子部品を組み込んだ板状体ｆが、振動、衝撃等によって損傷され易いという問題があった。また、前記従来のコーナパッドは、側壁を設けていないので、梱包物としての板状体ｆに対して閉じられた空間を確保することができない。そのため、板状体ｆに塵、埃、ごみ等が付着するという問題があった。
【０００６】
本発明は前記従来の問題点を解決し、落下したりぶつかったりした場合に、梱包物として電子部品を組み込んだ導光板等の板状体であっても、小さいサイズのものはもとより５インチ以上の大きなサイズに形成され、撓み性が大きいものでも振動、衝撃等によって損傷されることなく構造堅牢にかつ多量に搬送が行え、しかも箱体部内に連結板部に対し跨るように組込まれる内部保形枠の剛性により箱体部相互が連結板部に対して不用意に回動しないように保形性が発揮され、板状体の板状体挿入溝に対する挿入作業が容易に行え、梱包作業が簡単かつ確実に行えるとともに、製作は容易で量産可能で製作コストが安価な板状体の搬送用パッドを提供することを目的とものである。
【０００７】

【００１０】
また、本発明の請求項４に記載の発明は、熱可塑性合成樹脂シートを真空成形等の熱成形をすることにより成形した板状体の搬送用パッドであって、（イ）略矩形をなし交叉角が略直角に形成された底板および背板、並びに該底板および背板の左右両側に配置される側面略三角形の左側板および右側板とによりなる２ｎ個の箱体部と、（ロ）該箱体部に対して折曲可能に連結される２ｎ−１個の連結板部とを有、を有した板状体の搬送用パッドにおいて、
剛性材により平面略ロ形に形成される内部保形枠は、組上げ時に前記箱体部の前記底板相互が前記連結板部に対し同一平面まで折曲された時に対向する前記箱体部における前記背板、前記左側板および前記右側板に囲まれる内壁に略合致するように前記連結板部に跨って組込まれることにより前記箱体部相互の前記連結板部に対する保形性を発揮することを特徴とするという手段を採用した。
【００１５】
また、本発明の請求項５に記載の発明は、請求項１，請求項２,請求項３,または請求項４の何れかにおいて前記内部保形枠の長手方向の両端は、対向する箱体部における底板と背板とが交叉する隅角部に幅方向にわたり突出された緩衝用脚部内に嵌合され、前記連結板部に跨って組込まれることにより箱体部相互の連結板部に対する組上げ時の保形性を発揮することを特徴とするという手段を採用した。
【００１６】

【００１８】
【発明の実施の形態】
以下、本発明の実施の形態を図面に従って説明する。
図１は本発明の板状体の搬送用パッドの第１実施形態を示す分解斜視図、図２は組上げ状態を示す側面図、図３は展開状態から２つの箱状体を折曲する状態を示す側面図、図４は展開状態を示す側面図、図５は展開状態の平面図、図６は正面図、図７は板状体を梱包した状態の断面図である。
【００１９】
そして、本実施形態の板状体の搬送用パッドは熱可塑性合成樹脂シートを真空成形等の熱成形することにより形成される。そして、１は複数個、本実施形態では２個の箱体部であり、この箱体部１,１は略矩形をなし適宜角度、本実施形態では交叉角θが略直角にて交叉される底板２および背板３と該底板２および背板３の左右両側に配置される側面略三角形の左側板４および右側板５とにより断面略Ｌ形箱状に形成される。
【００２０】
前記熱可塑性合成樹脂としては、成形材料を容易にかつ多量に調達するために例えば発泡ポリプロピレン、ポリプロピレン、ポリスチレン、ポリ塩化ビニール、ＰＥＴ樹脂等が使用されるが、これらは例示でありこれに限られない。また、成形される本実施形態の板状体の搬送用パッドには、静電気帯電防止処理や、導電処理を行うこともあり、ある程度の通電性が必要となる弱電製品や、ごみの付着を嫌う板状体Ｔを梱包するための板状体の搬送用パッドを成形するのに対応される。
【００２１】
１ｂは対向する箱体部１,１における底板２と背板３とが交叉する隅角部１ａに幅方向Ｙにわたり底板２と背板３とが交叉する２等分線Ｍの延長方向外側に突出された緩衝用脚部であり、この緩衝用脚部１ｂは搬送中の振動や落下時の衝撃を吸収して板状体Ｔが傷付いたり、損傷されるのを防止するためのものである。
【００２２】
６は例えば成形時および不使用時には図４に示すように箱体部１,１の接続端間に連設され展開状態となる１個の連結板部であり、この連結板部６は使用に供する組付時には図４および図３の実線に示すような展開状態から図３の想像線で示すように折曲可能に連設される。
【００２３】
３ａ,４ａ,５ａ,６ａは前記背板３と、前記左側板４と、前記右側板５と、前記連結板部６との外側に形成された鍔部であり、この鍔部３ａ,４ａ,５ａ,６ａは背板５と、左側板４と、右側板５と、連結板部６との補強をはかるためのものである。
【００２４】
７は前記箱体部１,１の底板２および背板３の内壁にそれぞれＬ字状に沿って適宜個数が設けられた板状体挿入溝であり、この板状体挿入溝７内に例えば電子機器に使用される液晶モジュールの導光板、液晶基板、プリント配線基板、シリコンウエハー等の板状体Ｔの隣接する２つのコーナＣ,Ｃを搬送時に挿入するようになっている。
この板状体挿入溝７は、隣接する相互が０．５〜１０ｍｍにより形成される。この板状体挿入溝７の溝幅が０．５ｍｍ以上、好ましくは、１ｍｍ以上になるように形成される。溝幅が０．５ｍｍ未満では、輸送時に板状体Ｔが撓んで板状体Ｔ同士が接触することにより傷が付くので好ましくはない。また、１０ｍｍを越えると、嵩高くなり、板状体Ｔの輸送量が多くなるためである。
【００２５】
８は例えば合成樹脂、金属、木材等の剛性材により平面略ロ形に形成される内部保形枠であり、この内部保形枠８は組上げ時に図３の実線および図４に示すような展開状態から図３の想像線で示すように連結板部６に対して左右に連設される２個の箱体部１,１を略４５度折曲させることにより対向して起立させて箱体部１,１の底板２,２相互が連結板部６に対し同一平面Ｓまで折曲された時に対向する箱体部１,１内に組み込まれることにより背板３、左側板４および右側板５の内壁に合致するとともに前記連結板部６に跨って箱体部１,１相互の連結板部６に対する保形性を発揮するようになっている。こうして、板状体Ｔの搬送時における箱体部１,１内の挿入操作を容易かつ確実にする。
【００２６】
この際、内部保形枠８の長手方向の両端８ａ,８ａは、対向する箱体部１,１における底板２と背板３とが交叉する隅角部１ａに幅方向Ｙにわたり突出された緩衝用脚部１ｂ内に嵌合され、内部保形枠８は前記連結板部６に跨って組込まれることにより箱体部１,１相互の連結板部６に対する組上げ時の保形性を確実に発揮するようになる。
【００２７】
９は例えば合成樹脂、または金属等の可撓性材料により平面略ロ形に形成される外側固定枠であり、この外側固定枠９は組上げ時に前述のように箱体部１,１相互が連結板部6に対し同一平面Ｓまで折曲して起立された後に前記箱体部１,１における背板３、左側板４および右側板５を周囲から囲むように嵌合されて箱体部１,１間に跨って組付けられることにより箱体部1,１相互の連結板部６に対する組上げ後の保形性を発揮する。９ａは外側固定枠９の長手方向Ｉにおける両端付近の内側の左右に対応して設けられた係合凹状部であり、この係合凹状部９ａは箱体部１,１の左側板4および右側板5の鍔部４ａ,５ａに設けた係止凹部４ｂ,５ｂに係脱可能になる。
【００２８】
本発明の第１実施形態は以上の構成からなり、本実施形態の板状体の搬送用パッドは、例えば発泡ポリプロピレン、ポリプロピレン、ポリスチレン、ポリ塩化ビニール、ＰＥＴ樹脂等熱可塑性合成樹脂シートを真空成形等の熱成形することにより形成される。
【００２９】
この際、本実施形態の板状体の搬送用パッドは、前後左右の周囲と下面とが略矩形の壁面により全体的に略皿形に形成される従来のトレーとは異なり略矩形をなし、交叉角θが略直角に交叉される底板２および背板３と該底板２および背板３の左右両側に配置されて略矩形の壁面よりも面積が減少化される側面略三角形の左側板４および右側板５とにより断面略Ｌ形箱状に形成された２個の箱体部１,１と該箱体部１,１の接続端間に連設される１個の連結板部６とは成形時に図３の実線および図４に示すように展開状態に成形されるので、開放率が大きく、金型に対する接触面積の減少化がはかれて食い付きが少なく形成されるため、真空成形時に金型から熱可塑性合成樹脂よりなる物品搬送用パッドを円滑かつ確実に剥型することができ、生産効率は向上されて生産コストは安価になる。しかも、金型は構造簡単になり、金型代は安価になる。
【００３０】
それから、例えば電子機器に使用される液晶モジュールの導光板、液晶基板、プリント配線基板、シリコンウエハー等の板状体Ｔを搬送する等の使用時には先ず図３の実線および図４に示すような展開状態から図３の想像線で示すように連結板部６に対して左右に連設される２個の箱体部１,１を略４５度折曲させることにより対向して起立させる。
【００３１】
次いで、箱体部１,１の底板２,２相互が連結板部6に対し図２、図３の想像線に示すように同一平面Ｓまで折曲された時に対向する箱体部１,１内における背板３、左側板４および右側板５に囲まれる内壁に略合致するように前記連結板部６に跨がるように剛性を有する内部保形枠８を組込むと、内部保形枠８の剛性により箱体部１,１相互が連結板部6に対して不用意に回動して対向状態が形崩れないように保形性が発揮される（図１参照）。
【００３２】
その後、箱体部１,１の底板２および背板３の内壁にそれぞれＬ字状に沿って適宜個数が設けられた板状体挿入溝７内に例えば電子機器に使用される液晶モジュールの導光板、液晶基板、プリント配線基板、シリコンウエハー等の板状体Ｔの上下に隣接するコーナＣ,Ｃ；Ｃ,Ｃを挿入する。この時、対向する断面略Ｌ形箱状をなす箱体部１,１内に設けられる板状体挿入溝７,７は連結板部６を介してピッチのずれがなく自然に左右に対向するので、板状体挿入溝７,７内への板状体Ｔの挿入作業は迅速かつ正確に行える。
【００３３】
このように展開状態の物品搬送用パッドの箱体部１,１を対向して折曲して箱体部１,１内に内部保形枠８を連結板部６に対し跨がるように組込んで、内部保形枠８の剛性により箱体部１,１相互が連結板部6に対して不用意に回動しないように保形性を発揮させてから、板状体Ｔの四隅に配置される上下のコーナＣ,Ｃ；Ｃ,Ｃを図７に示すように上下２個の板状体の搬送用パッドの箱体部１,１；１,１の底板２および背板３の内壁にそれぞれＬ字状に沿って適宜個数が設けられた板状体挿入溝７内に挿入させ、所望個数の板状体Ｔを上下２個の物品搬送用パッド内に組み込む。その後に合成樹脂、または金属等の可撓性材料により平面略ロ形に形成される外側固定枠９を、背板３、左側板４および右側板５を周囲から囲むように嵌合させることにより外側固定枠９が箱体部１,１間に跨るように組付けられ、箱体部１,１；１,１内の板状体挿入溝７に板状体Ｔの上下のコーナＣ,Ｃ；Ｃ,Ｃを挿入させた状態で固定が行われる（図７参照）。
この際、外側固定枠９は,長手方向Ｉにおける両端付近の内側の左右に設けられた係合凹状部９ａが対向する箱体部１,１の左側板4および右側板5の鍔部４ａ,５ａに対応して設けた係止凹部４ｂ,５ｂに係脱可能に嵌合されるので、外側固定枠９の箱体部１,１に対する固定は迅速かつ確実になる。
なお、図には示さないが、図７に示すように箱体部１,１；１,１内の板状体挿入溝７に板状体Ｔの上下のコーナＣ,Ｃ；Ｃ,Ｃを挿入させてから上下２つの物品搬送用パッドの外周にゴム輪を捲回したり、テープを捲回することにより固定を確実にすることもできる。
こうして板状体Ｔの搬送時の梱包作業を終える。
【００３４】
従って、梱包物として板状体Ｔが、例えば撓み性が小さな１〜４インチの大きさの小さなサイズに形成される導光板のような場合はもとより、５インチ以上の大きなサイズに形成される導光板であり、撓み性が大きい場合にも、熱可塑性の合成樹脂シートを真空成形等の熱成形をすることにより全体形状が略皿形に成形される従来のトレーのように内部に横置きする方式とは異なり、本実施形態では上下２個の板状体の搬送用パッドの箱体部１,１；１,１の底板２および背板３の内壁にそれぞれＬ字状に沿って適宜個数が設けられた板状体挿入溝７内に板状体Ｔの隣接する上下のコーナＣ,Ｃ；Ｃ,Ｃを収納するという縦置収納方式を採用するので、板状体Ｔの収容枚数が多くなり、積載効率が向上するとともに従来のように多くのトレーを必要とすることなく所望数の板状体Ｔの搬送時の梱包が簡単な取り扱いで容易に行える。
【００３５】
この際、板状体挿入溝７は、隣接する相互が０．５〜１０ｍｍにより形成されるので、搬送時に板状体Ｔが撓んで板状体Ｔ同士が接触することがなく、しかも板状体Ｔが傷付くことなく、高品質を保証する搬送が行える。この時、溝幅が０．５ｍｍ未満では、搬送時に板状体Ｔが撓んで板状体Ｔ同士が接触することがあるので好ましくはないためであり、また、１０ｍｍを越えると、嵩高くなり、板状体Ｔの輸送量が多くなるためである。
しかも、従来の搬送方法のように保護フィルムを導光板等の板状体の表面に貼着して重合させたり、図１６ないし図１８に示すように緩衝材ｈを板状体ｆ相互間に挟むようにして重ね合わせる手間が省かれるとともに板状体Ｔに対する接触面積が板状体挿入溝７だけと少ないので、板状体Ｔの搬送時の梱包が容易な取扱操作により簡単に行えるとともにごみの発生はなくなり板状体Ｔに汚れや傷が生ずることなく、高品質のを信頼性のある製品に梱包するのに適する。
【００３６】
しかも、本実施形態の板状体の搬送用パッドは、前記のように熱可塑性合成樹脂シートを真空成形等の熱成形することにより形成され、２個の箱体部１,１は略矩形をなし交叉角θが略直角に形成された底板２および背板３の左右両側に側面略三角形の左側板４および右側板５が配置され、しかも２個の箱体部１,１に対して折曲可能に連結される１個の連結板部6とから成形されるので、図１６ないし図１８に示すような４つの従来のコーナパッドが、４個とも、ヒンジ部ｃで結合された対をなす当て板ａ,ｂの両側に側壁を設けるのとは異なり、落下したりぶつかったりした場合に、梱包物としての板状体Ｔに圧縮しようとする力が直接かかることはないとともに従来のコーナパッドのようにヒンジ部ｃを用いていないため、閉じようとする力が直接板状体Ｔにかかることはない。そのため、電子部品を組み込んだ板状体Ｔが、振動、衝撃等によって損傷されることなく構造堅牢に搬送に供される。
【００３７】
しかも、対向する箱体部１,１における底板２と背板３とが交叉する隅角部１ａには幅方向Ｙにわたり略直角の交叉角θに対する２等分線Ｍの延長方向外側に緩衝用脚部１ｂが突出され、また、前記左側板４と、前記右側板５と、前記連結板部６との外側に鍔部４ａ,５ａ,６ａが形成されているので、箱体部１,１は構造堅牢になり搬送時または落下時においても振動や衝撃等から板状体Ｔを損傷なく保護する。
また、前記のように２個の箱体部１,１は、左側板４および右側板５を設けているので、梱包物としての板状体Ｔに対して閉じられた空間を確保することも可能となり、板状体Ｔに塵、埃、ごみ、傷等が付着しないで済む。
【００３８】
また、図８ないし図１１に示すものは本発明の板状体の搬送用パッドの第２実施形態を示すものである。
この実施形態では、底板２、背板３、連結板部６の設置幅を前記第１実施形態より広くして対向する箱体部１,１を幅広に形成するとともに箱体部１,１の底板２および背板３の内壁にそれぞれＬ字状に沿って設けられる板状体挿入溝７の設置数を増加することにより多数の板状体Ｔの梱包数を増大するようにして積載効率を向上するほか、対向する箱体部１,１における底板２と背板３とが交叉する２等分線の延長方向外側に突出する緩衝用脚部１ｂ,１ｂの突出度を大きくして振動や衝撃等に対する緩衝性を大きく設定した点が異なり、そのほかは前記第１実施形態と同様の構成、作用である。
【００３９】
図１２および図１３に示すものは本発明の第３実施形態である。
この実施形態は、前記第１実施形態および第２実施形態のように板状体Ｔが四隅にコーナＣ,Ｃ；Ｃ,Ｃを有する矩形ないしは正方形に形成されたものとは異なり、ＣＤ（コンパクトディスク）やＤＶＤ（デジタル・ビデオ・ディスク）のような円盤状に形成されたものの搬送に適する。
すなわち、２個の箱体部１,１は、略矩形をなす底板２および背板３の交叉角θが直角よりも大きな略鈍角に形成されたことにより円盤状の板状体Ｔの搬送時に、断面略Ｌ形箱状に形成される２個の箱体部１,１の底板２および背板３の内壁に沿って設けた適宜個数の板状体挿入溝７と２個の箱体部１,１の接続端間に折曲可能に連設する連結板部６に設けた板状体挿入溝７とに外周を挿入することにより図１３では２個の箱体部１,１の底板２、背板３、連結板部６に対して５個所で点接触させるように支持して梱包し、搬送を行うようにした点が異なるほかは、前記第１実施形態および第２実施形態と同様の構成、作用である。
【００４０】
さらに、図１４および図１５に示すものは本発明の第４実施形態である。
この実施形態では、板状体Ｔが図に示すように矩形に形成されるものほか、正方形、図には示さないが六角形、八角形等の多角形に形成されるものを梱包し、搬送する場合に適するものである。
すなわち、略矩形をなし交叉角θが略直角に形成された底板２および背板３と、該底板２および背板３の左右両側に配置される側面略三角形の左側板４および右側板５とによりなる２ｎ個、図示では４個の箱体部１,１；１,１と、該箱体部１,１；１,１に対して接続端間で折曲可能に連結される２ｎ−１個、図示では３個の連結板部６,６,６とから１個の物品搬送パッドが成形される。
なお、上記説明においてｎは整数である。しかも、本実施形態は例えば図には示さないが、板状体Ｔが六角形に形成される場合は、１個の搬送パッドに６個の箱体部１と５個の連結板部６が箱体部１の接続端間に設けられ、また板状体Ｔが八角形の場合は、１個の搬送パッドに８個の箱体部１と７個の連結板部６とが箱体部１の接続端間にそれぞれ設けられる。
【００４１】
そして、図示する実施形態では、前記第１実施形態が板状体Ｔの搬送時に、四隅に配置する４つのコーナＣ,Ｃ；Ｃ,Ｃを上下２個の搬送パッドの対向する箱体部１,１；１,１に設けられる板状体挿入溝７内に挿入することにより梱包が行われていたが、この実施形態では１つの搬送パッドに備えられた４個の箱体部１,１；１,１の底板２および背板３に設けられた適宜個数の板状体挿入溝７内に矩形の板状体ＴのコーナＣ,Ｃ；Ｃ,Ｃを挿入して梱包を行うようにして梱包作業を効率化したほかは、第１実施形態と同様の構成、作用である。
【００４２】
また、本実施形態を進展させれば例えば図には示さないが、板状体Ｔが六角形に形成される場合は、１個の搬送用パッドに６個の箱体部１と５個の連結板部６とが箱体部１の接続端間に設け、また板状体Ｔが八角形の場合は、１個の搬送パッドに８個の箱体部１と７個の連結板部６とを箱体部１の接続端間にそれぞれ設けることにより、それぞれ六角形の板状体Ｔ、八角形の板状体Ｔの外周を箱体部１内に設けた板状体挿入溝７に挿入することにより１個の搬送パッドにより周囲から包囲して梱包することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a plate-like transport pad, and particularly stores and transports a plate-like body such as a liquid crystal substrate used in an electronic device, a light guide plate of a liquid crystal module, and a printed wiring board, or temporarily stores it. It is used to do.
[0002]
[Prior art]
For example, liquid crystal module light guide plates used in electronic equipment use highly transparent acrylic resin, for example, and they are extremely disliked from dust, scratches, and dirt. , Could not be transported and stored.
Then, as a method for transporting a plate-like body such as a light guide plate, taking into account the flexibility of each size, for example, the light guide plate having a size of 1 to 4 inches and the light guide plate having a size of 5 inches or more are transported separately. The transport method was different.
For example, the light guide plate formed in a small size of 1 to 4 inches with small flexibility is formed into a substantially dish shape by thermoforming a thermoplastic synthetic resin sheet such as vacuum forming. It has been transported using a packing product such as a box which is placed horizontally in a tray or is formed using a synthetic resin foam material.
In addition, the light guide plate formed in a large size of 5 inches or more has a large flexibility, so that the protective film is attached to the surface of the light guide plate to be polymerized, or transported, or A thin cushioning material has been transported by overlapping it so that it is sandwiched between plate-like bodies.
[0003]
As described above, there has been a method of carrying a sheet after a buffer material is sandwiched between the plate-like bodies and stacked.
That is, for transporting a plate-like body as a package, a cushioning material and a plate-like body made of a low-shaped low-foam body whose outer circumference is larger than the outer circumference of the plate-like body and whose inner circumference is slightly smaller than the plate-like body Are stacked in order and fixed with a rubber ring or tape. However, this conventional method generates powder when punching a square-shaped plate-like body, and accordingly, when fixing a plurality of aggregates that overlap the plate-like body and the buffer material, or at the time of conveyance As a result, the shock absorbing material and the plate-like member rub against each other due to vibrations, and the electronic component incorporated in the plate-like member is damaged extensively.
[0004]
As a conventional technique for solving the above problems, for example, there is an invention of JP-A-5-319456. As shown in FIGS. 16 to 18, the present invention includes four corner pads having a pair of contact plates a and b and a hinge portion c and disposed at four corners of the assembly d. The plates a and b have a flat plate shape made of foamed resin applied to adjacent end portions sandwiching the corner of the plate-like body f as a package, and are used in combination with an angle formed by the adjacent end portions of the corner. The pair of contact plates a and b have a groove g, and the groove g is provided in parallel at a desired pitch on the inner surface of the contact plates a and b facing the corner of the flat plate-like body f. The end edge of the body f is fitted and held.
[0005]
[Problems to be solved by the invention]
However, in the conventional invention as shown in FIG. 16 to FIG. 18, the four corner pads arranged at the four corners with respect to the plurality of aggregates d in which the plate-like body f and the buffer material h are overlapped are all four. Since the side walls are not provided on both sides of the pair of contact plates a and b engaged with the hinge portion c, the force to compress the plate-like body f as a package is directly applied when it falls or hits. At the same time, a force for closing the hinge part c is directly applied. Therefore, there is a problem that the plate-like body f incorporating the electronic component is easily damaged by vibration, impact, or the like. Moreover, since the said conventional corner pad does not provide the side wall, the space closed with respect to the plate-shaped body f as a package cannot be ensured. Therefore, there has been a problem that dust, dirt, dust, and the like adhere to the plate-like body f.
[0006]
  The present invention solves the above-mentioned conventional problems, and when it falls or collides, even if it is a plate-like body such as a light guide plate incorporating an electronic component as a package, it is 5 inches or more from a small size. It is formed in a large size, and even a highly flexible material can be transported robustly and in large quantities without being damaged by vibration, impact, etc.Due to the rigidity of the internal shape retaining frame incorporated so as to straddle the connecting plate part in the box part, the shape retaining property is exhibited so that the box parts do not rotate unintentionally with respect to the connecting plate part. Can be easily inserted into the plate-like body insertion groove,Providing a plate-shaped transport pad that can be easily and reliably packed, is easy to manufacture, can be mass-produced, and is inexpensive to manufacture.With the purpose ofIs.

[0028]
1st Embodiment of this invention consists of the above structure, and the pad for conveyance of the plate-shaped body of this embodiment vacuum-molds thermoplastic synthetic resin sheets, such as a foaming polypropylene, a polypropylene, a polystyrene, a polyvinyl chloride, PET resin, for example It is formed by thermoforming.
[0029]
At this time, the transport pad of the plate-like body of the present embodiment has a substantially rectangular shape unlike a conventional tray in which the front and rear, left and right periphery and the lower surface are formed in a substantially dish shape as a whole by a substantially rectangular wall surface, A bottom plate 2 and a back plate 3 that cross each other at a substantially right angle, and a left side plate 4 having a substantially triangular side surface that is disposed on both the left and right sides of the bottom plate 2 and the back plate 3 and has a smaller area than a substantially rectangular wall surface. And two box bodies 1, 1 formed in a substantially L-shaped cross section by the right side plate 5, and one connecting plate 6 connected between the connection ends of the box bodies 1, 1, 3 is formed in the unfolded state as shown in the solid line of FIG. 3 and FIG. 4 at the time of molding, so that the open ratio is large, the contact area with the mold is reduced, and the formation of the bite is reduced. Sometimes it is possible to smoothly and reliably peel off the article transfer pad made of thermoplastic synthetic resin from the mold, Production efficiency is improved and production costs are reduced. In addition, the structure of the mold becomes simple and the mold cost is low.
[0030]
Then, for example, when transporting a light guide plate of a liquid crystal module, a liquid crystal substrate, a printed wiring board, a silicon wafer, or the like used for an electronic device, the development shown in FIG. From the state, as shown by the imaginary line in FIG. 3, the two box parts 1, 1 connected to the left and right with respect to the connecting plate part 6 are bent to face each other by bending approximately 45 degrees.
[0031]
Next, the box parts 1 and 1 that face each other when the bottom plates 2 and 2 of the box parts 1 and 1 are bent to the same plane S as shown by the imaginary lines in FIGS. When the internal shape retaining frame 8 having rigidity so as to straddle the connecting plate portion 6 so as to substantially match the inner wall surrounded by the back plate 3, the left side plate 4 and the right side plate 5 is incorporated, the internal shape retaining frame Due to the rigidity of 8, the shape retention is exhibited so that the box parts 1 and 1 are inadvertently rotated with respect to the connecting plate part 6 and the opposed state is not lost (see FIG. 1).
[0032]
Thereafter, the liquid crystal module used in, for example, an electronic device is introduced into the plate-like body insertion grooves 7 provided in appropriate numbers along the L-shape on the inner walls of the bottom plate 2 and the back plate 3 of the box portions 1, 1. Corners C, C; C, C adjacent to the upper and lower sides of a plate-like body T such as an optical plate, a liquid crystal substrate, a printed wiring board, and a silicon wafer are inserted. At this time, the plate-like body insertion grooves 7 and 7 provided in the box portions 1 and 1 having a substantially L-shaped box shape facing each other are naturally opposed to the left and right via the connecting plate portion 6 without any deviation in pitch. Therefore, the operation of inserting the plate-like body T into the plate-like body insertion grooves 7, 7 can be performed quickly and accurately.
[0033]
In this way, the box parts 1, 1 of the unfolded article conveying pad are bent oppositely so that the internal shape retaining frame 8 straddles the connecting plate part 6 in the box parts 1, 1. The four corners of the plate-like body T are assembled after the shape-retaining property is exhibited so that the box-shaped portions 1 and 1 do not rotate relative to the connecting plate portion 6 due to the rigidity of the internal shape-retaining frame 8. The upper and lower corners C, C; C, C arranged in the upper and lower corners 1, 1; the bottom plate 2 and the back plate 3 of the transport pad of the upper and lower two plate-like bodies as shown in FIG. The desired number of plate-like bodies T are assembled into the upper and lower two article-conveying pads by inserting them into plate-like body insertion grooves 7 each having an appropriate number of L-shaped inner walls. Thereafter, the outer fixed frame 9 formed in a substantially plane shape by a synthetic resin or a flexible material such as metal is fitted so as to surround the back plate 3, the left plate 4 and the right plate 5 from the periphery. The outer fixed frame 9 is assembled so as to straddle between the box parts 1, 1, and the upper and lower corners C, C of the plate-like body T are inserted into the plate-like body insertion grooves 7 in the box parts 1, 1; ; Fixing is performed with C and C inserted (see FIG. 7).
At this time, the outer fixed frame 9 includes the left side plate 4 of the box portions 1 and 1 and the flange portion 4a of the right side plate 5 opposed to the engagement concave portions 9a provided on the inner left and right sides in the longitudinal direction I. Since the engaging recesses 4b and 5b provided corresponding to 5a are detachably fitted, the fixing of the outer fixing frame 9 to the box parts 1 and 1 is quick and reliable.
Although not shown in the figure, as shown in FIG. 7, the upper and lower corners C, C; C, C of the plate-like body T are formed in the plate-like body insertion grooves 7 in the box portions 1, 1; Fixing can be ensured by winding a rubber ring or winding a tape around the outer periphery of the upper and lower two article transport pads after insertion.
Thus, the packing operation at the time of transporting the plate-like body T is completed.
[0034]
Therefore, the plate-like body T as a package is not limited to a light guide plate having a small flexibility of 1 to 4 inches, for example. Even if it is a light plate and has great flexibility, the thermoplastic synthetic resin sheet is placed inside like a conventional tray whose overall shape is formed into a substantially dish shape by thermoforming such as vacuum forming. Unlike the system, in this embodiment, the number of the upper and lower two plate-shaped transport pad box portions 1, 1; Since the vertical storage system of storing the upper and lower corners C, C; C, C adjacent to each other in the plate-like body T is adopted in the plate-like body insertion groove 7 provided with the number of the plate-like bodies T. Increases loading efficiency and requires more trays as before Thus, the packaging of the desired number of plate-like bodies T during transportation can be easily performed with simple handling.
[0035]
At this time, since the plate-like body insertion grooves 7 are formed with 0.5 to 10 mm adjacent to each other, the plate-like bodies T do not bend during transportation and the plate-like bodies T do not come into contact with each other. The body T can be transported to ensure high quality without being damaged. At this time, if the groove width is less than 0.5 mm, it is not preferable because the plate-like bodies T may be bent at the time of conveyance and the plate-like bodies T may come into contact with each other. This is because the transport amount of the plate-like body T increases.
