【発明の属する技術分野】
本発明は、梱包副資材等の廃棄物を発生させず、所望の順序で積み降ろしが可能なガラス板の輸送用パレットに関する。
【０００２】
【従来の技術】
従来より、ガラス板等の板状体を輸送運搬するにあたり、パレット上に多数枚縦積みして輸送するが、輸送中の荷崩れや転倒を防止するためさまざまな工夫がされている。
【０００３】
また、ガラス板をパレットの背側に凭れ掛け、積載した場合には、ガラス板間には合紙等の緩衝材が必要となり、さらに、輸送中の急ブレーキや振動等により、ガラス板の横ズレ等によってガラス板同士の接触によって発生するキズを防止するために、ガラス板をポリプロピレン樹脂製のベルト状のＰＰバンド等によってパレットの背枠等に固定する等の手段が良く行われている。
【０００４】
しかしながら、これらの梱包副資材は、繰り返し使用することができないので産業廃棄物となって、廃棄処理するにも費用が掛かってしまうという問題点があった。
【０００５】
これらの副資材を使わないようにして産業廃棄物をなくし、パレットを繰り返し使用できるようにしたものとして、例えば、本出願人による出願に係る特開平１１−４３１８７号公報には、立掛け積層する複数枚の板状体をパレットの背板側に固定する方法において、長さ調整具により長さ調整自在な非伸縮性素材のバンドと、伸縮性素材のバンドとを連結具を介して連結し、非伸縮性バンドの一端をパレットの背板側に固定し、前記連結部の１つを着脱分離自在な連結具で連結させるようにし、該バンドを縦方向及び／又は横方向に少なくとも１つ以上設け、複数枚の板状体の傾倒を抑止させるパレットに積載した板状体の固定方法が開示されている。
【０００６】
また、同じく本出願人による出願に係る特開平１１−９１９４４号公報には、ガラス板を縦姿勢で１枚毎に離隔して積載する搬送台車であって、底板上にガラス板の積載方向と平行に複数本の長尺部材を並設し、該底板の角部近傍より上方に縦フレームを立設し、各縦フレームの上部間を連結する横フレームを設け、該横フレーム間で前記長尺部材の長手方向と直交する方向に複数の貫通孔を設けた補助フレームを着脱自在に設け、前記長尺部材に設けた複数の凹部の夫々に上方に立設する複数のロッドを埋設させると共に、該ロッドを前記貫通孔に遊挿させ、該ロッドにより１枚毎に離隔して立設するガラス板の下部桟内にガラス板の積込み、積降ろし時に摺動回転する回転コロを設けたガラス板用積載台車が開示されている。
【０００７】
前記の例示以外にも、床部及び背枠側に硬質樹脂製でＶ溝形状からなるガラス間隔保持用凹状材を配置し、ガラス板を背側の縦辺と底辺との２辺で保持すると共に、背枠上部側に装着されたゴムバンドを引き出し、ガラス板の前枠側床部に固定し、ゴムバンドの途中に設けたＬ型の金具でガラス板のコーナー部を押さえてガラス板を固定するパレットが使われている。
【０００８】
【発明が解決しようとする課題】
前記特開平１１−４３１８７号公報に記載のものは、ガラス板をパレット背側より手前側に積み重ね状態で積載して梱包するため、積載順は大寸法から小寸法へと積載することが多く、この場合の取出し時は手前側に積載された小サイズから取り出さざるを得ない。
【０００９】
また、このようにして積載されたガラス板をユーザーに出荷した場合、かならずしも、ユーザー側が必要とする順序と一致して積載されておらず、ユーザーの所望する順序となるようにするために、積載されたガラス板を中抜きで取り出すことも、このような荷姿においては容易ではない。
【００１０】
また、特開平１１−９１９４４号公報に記載のものは、積載された種々のガラス板がそれぞれロッドによって離隔され、所望のガラス板の積み降ろしが自在であるが、場内運搬用として有用な運搬台車であるので、ガラス板の両縦辺側を固定する手段を備えておらず、このままではトラック等によって長距離輸送することはできない。
【００１１】
さらに、ガラス板を床部及び背枠側に当接するように配置したガラス間隔保持用凹状材と、背枠上部側に装着されたゴムバンドによってガラス板の上辺手前のコーナー部を固定するようにしたパレットの場合は、背枠基準で積載するため大サイズのガラス板間に挟まれた小サイズのガラス板の取り出しが容易ではなく、また、ゴムバンドによってガラス板のコーナー部を押さえつけるだけであるので、長距離輸送時のガラス板の固定が充分とはいえず、ガラス板同士が接触する恐れがあった。
【００１２】
【課題を解決するための手段】
本発明は、上記問題点の解決を図る、すなわち梱包資材等の廃棄物を発生させず、異なる寸法、厚みのガラス板を所望の順序で、所望の位置に積み降ろしが可能であり、立て掛けて積層したガラス板の取り出しも容易であり、また長距離の輸送によってもガラス板同士の接触によるキズや、破損もないガラス板用のパレットを目的としたものである。
【００１３】
すなわち、本発明は、縦横に枠組みした床部と、該床部の一端より固着立設した背枠と、前記床部上の背枠と対向する辺に着脱自在に設けた前枠と、前記背枠の上部両側部に軸支し、前枠の上部両側部に係止するサイドストッパーと、からなるガラス板を縦姿勢で積載するパレットにおいて、前記前枠と背枠に直交する方向に所定の間隔で床部上に並設した複数本のチャンネル状の長尺部材と、該長尺部材上に所定間隔を設けてガラス板の下端辺を支持する支持部材と、前記背枠の上辺近傍に設けたロッドに軸着し回動自在な複数本の仕切部材の下端に長さ調節自在なベルトを介して接続した連結金具を、前枠側の床部に設けた係止金具に係止させて、仕切部材をガラス板の対角線状に配設して隣接するガラス板同士を仕切り、さらにガラス板の前枠側縦辺に当接する前部ストッパー及び前部押圧具と、ガラス板の背枠側縦辺を押圧する前後方向に移動自在な後部押圧手段によってガラス板を挟持固定したことを特徴とするガラス板用パレットである。
【００１４】
また、本発明は、ガラス板の積載時に、ガラス板の縦辺に当接して前枠基準で整列させる前部ストッパーを前記前枠側の床部上に反転離脱自在に設けたことを特徴とする上述のガラス板用パレットである。
【００１５】
あるいはまた、本発明は、前記前枠の少なくとも１つ以上の前枠横桟の夫々に反転離脱自在に設けた前部押圧具を一体的にあるいは分割して設け、ガラス板の輸送時にガラス板の縦辺に当接させるようにしたことを特徴とする上述のガラス板用パレットである。
【００１６】
さらに、本発明は、前記後部押圧手段が、矩形部材より上方に突設した棒状部材により嵌挿部材に遊挿保持し、該嵌挿部材に軸支したアームの先端に押さえ金具を軸支させ、前記嵌挿部材上部に載置した重り部材の自重により、アームを下方に押し下げ、ガラス板の後部側縦端縁を押さえ金具で押圧し、チャンネル状の長尺部材内にスライド移動自在に設けた前記矩形部材を前記重り部材によるアームの傾動反力によって長尺部材内で回動して長尺部材の内壁に押し当てることによって後部押圧手段の位置を固定するようにしたことを特徴とする上述ガラス板用パレットである。
【００１７】
さらにまた、本発明は、前記支持部材、前部ストッパー、前部押圧具、後部押圧手段の押え金具のガラス板との当接部の断面形状が、Ｍ字状、Ｖ字状、Ｕ字状等の凹溝部を有していることを特徴とする上述のガラス板用パレットである。
【００１８】
【発明の実施の形態】
本発明は、図１に示すように、縦横に枠組みした床部２の一端辺より背枠２０を固着立設し、前記床部２上で背枠２０と対向する辺に着脱自在に立設する前枠１０を設け、さらに前記背枠２０の支柱２１の上部側部に軸支したサイドストッパー５を前枠１０の支柱１１の上部側部のフック１７に係止させたガラス板Ｇを縦姿勢で積載するパレット１において、
前記床部２上に、複数本のチャンネル状の長尺部材３を前枠１０と背枠２０に直交する方向に所定の間隔で並設し、該長尺部材３の上面にはガラス板Ｇの下端辺を支持する支持部材４を所定間隔をおいて設けた。
【００１９】
前記床部２には前枠１０の支柱１１を挿入可能な前枠挿入部６が設けてある。
【００２０】
また、前記隣接するガラス板Ｇ、Ｇ同士を離隔する仕切手段３０を背枠２０の上部側から前枠１０の下部に対角線状に設け、隣接するガラス板Ｇ、Ｇ同士を該仕切手段３０によって仕切り、ガラス板Ｇ、Ｇ同士の接触防止とガラス板Ｇの転倒を防止できるようにした。
【００２１】
該仕切手段３０は、図６に示すように前記背枠２０の上辺近傍、すなわち支柱２１の上端間に水平に設けたロッド３１に複数の円筒部材３２、３２、・・を外接させ、該円筒部材３２、３２、・・にそれぞれ長尺で板状の仕切部材３３、３３、・・を固着し、各仕切部材３３の下端に長さ調整自在な調整ベルト３４を介して連結金具３４ａを接続した。前記円筒部材３２、３２、・・と仕切部材３３を合計した長さは、隣り合って積載するガラス板Ｇ、Ｇのピッチに一致しており、積載するガラス板Ｇ、Ｇ間の中心位置に仕切部材３３が配置されるようにしたので、仕切部材３３が位置ずれを起こすことはない。
【００２２】
また、図７（ａ）〜（ｃ）に示すように、複数の長尺部材３、３・・の前枠１０側の先端部で各長尺部材３、３間に板状の係止部材３５を起倒自在に設け、該係止部材３５には少なくとも１つ以上の係止溝３６、３６、・・を設けている。前記仕切部材３３と係止部材３５とを連結しようとする場合は、該係止部材３５を起立させ、図８に示すように、前記連結金具３４ａと所望の係止溝３６とを係止させて、仕切部材３３が極力ガラス板Ｇの略対角線状になるように配設する。
【００２３】
尚、前記係止部材３５は、複数の長尺部材３、３、・・の略先端部を貫くように設けた係止用ロッド３８が係止部材３５の下端及び係止部材３５に固設したＬ型部材に設けたＬ字孔３７内を遊挿しており、図７（ａ）の状態で係止部材３５は係止部材３５の下端とチャンネル状の長尺部材３の底部とが当接状態で起立姿勢が保たれ、図７（ｂ）に示すように、係止部材３５をＬ字孔３７に沿って水平に移動後持ち上げると、係止部材３５の下端とチャンネル状の長尺部材３の底部間に隙間ができて係止部材３５が転倒可能な状態となり床部２内に収納可能となる。
【００２４】
さらに、図１に示すように、床部２に設けた前部ストッパー１３と、前枠１０に設けた前部押圧具１２をガラス板Ｇの前枠１０側縦辺に当接させることによって、ガラス板Ｇの立設位置を前枠１０基準として揃え、ガラス板Ｇの背枠２０側縦辺については、後部押圧手段４０の押え部材４５をガラス板Ｇの縦辺に押圧させてガラス板Ｇを挟持固定できるようにした。
【００２５】
前記前部ストッパー１３は、図９に示すように、前枠１０側の床部２上に取付部材１５を介して鋸歯状部を有する板状部材を蝶番１４によって反転離脱自在に設けられており、鋸歯のピッチは当接するガラス板Ｇ、Ｇ間のピッチに一致させている。
【００２６】
ガラス板Ｇをパレット１上に積載する時には、ガラス板Ｇの前枠１０側の縦辺を前部ストッパー１３の鋸歯状部に当接させてガラス板Ｇを前枠１０側に一列に揃えて整列させるものであり、ガラス板Ｇをパレット１上から取り出し時には、図１０に示すように、該前部ストッパー１３の板状部材を反転させてガラス板Ｇから鋸歯状部を引き離せば、スムーズな取出しが可能である。
【００２７】
さらに、図１１に示すように、前記前枠１０に設けた前部押圧具１２は、少なくとも１つ以上の前枠横桟１６の夫々に鋸歯状部を有する板状部材を反転離脱自在に設けたもので、鋸歯のピッチは当接するガラス板Ｇ、Ｇのピッチに一致させ、前枠幅に相当する幅について一体的に設けても良いし、あるいは複数個に分割して設けても良い。
【００２８】
前記後部押圧手段４０は、図３、図４に示すように、チャンネル状の長尺部材３内をスライド自在な矩形部材４１の側部よりチャンネル状長尺部材３の開口部を経て長尺部材３の上部まで延びる取付部材４９を設け、該取付部材４９の上端より上方に突設し固定した棒状部材４２に外接した嵌挿部材４３に下端部を軸支したアーム４４の先端にガラス板Ｇの後部側の縦辺に当接する押え金具４５を下端部を軸支させ、前記嵌挿部材４３の上部に重り部材４６を載置した。
【００２９】
該重り部材４６はアーム４４の下部側に荷重がかかっているので、その自重により、アーム４４を下方に押し下げ、アーム４４の先端に軸支した押え金具４５でガラス板Ｇの後部側縦端縁を押圧することになる。
【００３０】
前記チャンネル状の長尺部材３内をスライド移動自在に設けた前記矩形部材４１は、前記重り部材４６によりアーム４４を傾動させる押圧力の反力によって棒状部材４２が逆方向である後方側に傾動し、該傾動によって棒状部材４２に連結固定した矩形部材４１を長尺部材３内で傾動させて、矩形部材４１を長尺部材３の内壁上面及び下面に押し当てることによって後部押圧手段４０の位置が固定され、後部押圧手段４０の位置がずれることはない。
【００３１】
押え部材４５の高さ方向の調整は、棒状部材４２の例えば上下２カ所に設けた位置調整孔５０のいずれかを選択し、嵌挿部材４３を該位置調整孔５０に合わせて上下位置調節ピン４７を差し込めば、押え部材４５の高さを上下２段で調整可能であり、該位置調整孔は例示した２カ所に限定されるものではなく、複数個設けても良い。
【００３２】
また、棒状部材４２の頂部には上端ストッパー４８を設け、嵌挿部材４３や重り部材４６の外れを防止させるものである。
【００３３】
以上に説明した、長尺部材３上の前記支持部材４、床部２上の前部ストッパー１３、前枠１０の前部押圧具１２、後部押圧手段４０の押え金具４５のそれぞれについてガラス板Ｇとの当接部の断面形状が、Ｍ字状、Ｖ字状、Ｕ字状等の凹溝部を有していることが望ましい。また、支持部材４の材質としては、滑りやすい樹脂製が好ましい。
【００３４】
このように、パレット１上に積載された異なる寸法のガラス板Ｇを所望の位置より所望の順序で積み降ろしでき、積載するガラス板Ｇのサイズが異なっても、ガラス板Ｇの前部側の縦辺を前部ストッパー１３及び前部押圧具１２に当接させ、後部側の縦辺をガラス板Ｇの１枚毎に後部押圧手段４０によって押さえてガラス板Ｇを挟持させ、確実に固定させることができるので、長距離の輸送にも対応ができ、安全である。
【００３５】
また、該後部押圧手段４０の押え部材４５は、前後方向、上下方向にワンタッチで移動調節可能であるので、ガラス板Ｇの寸法の変化に容易に対応できる。
【００３６】
さらに、ガラス板Ｇ、Ｇ間に仕切り手段３０によって、略対角線状に仕切部材３３を設けたので、ガラス板Ｇ、Ｇ同士の接触や、ガラス板Ｇの転倒を防ぐことができる。
【００３７】
さらにまた、ガラス板Ｇを前枠１０側に揃えて積載させるので、パレット１上に積載されたガラス板Ｇより所望の位置のガラス板Ｇを取り出すときに、背枠２０基準に積載したものと比べて大幅に取り出しが簡単であり、作業効率がよい。
【００３８】
また、ガラス板Ｇの積載方向は、前枠１０側方向から挿入するようにしても良いが、側面方向から載置するようにしても良い。
【００３９】
以上、好適な実施の形態について述べたが、本発明はこれに限定されるものではなく種々の応用が考えられる。
【００４０】
本発明のガラス板用パレット１に積載されるガラス板Ｇとしては、複層ガラスの輸送に限らず、強化ガラス板、半強化ガラス板、生板等の単板、あるいは複数枚の強化ガラス相互、あるいは強化ガラスと生板ガラスを組み合わせてＰＶＢやＥＶＡ等の中間膜または樹脂注入で接着した合わせガラス、および前記のガラス板に飛散防止樹脂膜を貼着したフラットなガラス板であってもよく、建築用、車両用、産業用、家具用、あるいはその素板等も対象となり、その形状は矩形のものが対象となるが、板厚は問わない。
【００４１】
以下に本発明のガラス板用パレット１の使用方法について詳述する。
【００４２】
まず、ガラス板Ｇを本発明のパレット１上に積み込む場合について説明する。
【００４３】
積み込み作業の所定位置に空のパレットを載置し、前枠のフック１７に係止されているサイドストッパー５、５を取り外す。引き続いて、床部２の前枠挿入部６、６に嵌合された前枠１０の両支柱１１、１１を引き抜いて取り外す。
【００４４】
床部２上に取付部材１５を介して反転自在に設けた前部ストッパー１３の鋸歯状部をパレット１の内側にセットする。
【００４５】
１枚目のガラス板をパレットの最側部側に積載する前に、１枚目のガラス板面の外側にも予め仕切手段による仕切部材をセットしておく必要がある。このためまず、該位置の係止部材３５を起立固定させ、調整ベルト３４を接続した仕切部材３３を係止部材３５の係止溝３６に係止させ、積み込もうとする１枚目のガラス板Ｇの寸法に合うような係止溝３６の位置を適宜選択し、調整ベルト３４の長さを調整してセットする。
【００４６】
次に、ガラス板Ｇをパレット１の前方側、あるいは側方側のいずれかより支持部材４上に載置するが、ガラス板面の向こう側面にセットした仕切部材にガラス板を凭れ掛けできるように、パレットを僅かに向こう側に傾斜させておくと好ましい。
【００４７】
ガラス板を載置した後は、ガラス板の手前側にも仕切部材３５をセットしていく。つまり、係止部材３５を起立固定後、調整ベルト３４を接続した仕切部材３３を係止部材３５の係止溝３６に係止させ、ガラス板Ｇの寸法に合わせて係止溝３６の位置を適宜選択し、調整ベルト３４の長さを調整してセットすればよい。
【００４８】
続いて、前回に積載したガラス板Ｇの縦辺を前部ストッパー１３に当接するまで移動させ、前枠基準で揃えた後、後部押圧手段のセットを行う。
【００４９】
後部押圧手段のセットは、後部押圧手段４０の押え部材４５がガラス板Ｇの後部縦辺に当接するように移動調整後、高さ方向に調整する必要があれば、アーム４４を軸支している嵌挿部材４３を上下位置調節ピン４７によって調整し、重り部材４６でアーム４４を傾動させると共に、前後方向の位置も固定させてガラス板Ｇを前後両端より挟持固定させればよい。
【００５０】
以上の作業を所定枚数のガラス板Ｇに対し繰り返して行い、所定枚数のガラス板Ｇの積載が完了後は、前枠１０を前記床部２の前枠挿入部６内に挿入嵌合して、固定する。
【００５１】
この時点で、前枠１０の横桟１６に設けた前部押圧具１２の鋸歯状部を順次反転させて、ガラス板Ｇの縦辺に当接するように合わせていき、最後に、サイドストッパー５を前枠１０の両支柱１１、１１に設けたフック１７、１７にセットする。
【００５２】
次に、パレット１よりガラス板Ｇを取り出す場合について説明する。
【００５３】
まず、所定位置にガラス板Ｇを積載したパレット１を載置し、サイドストッパー５、５を外し、前枠１０の両支柱１１、１１に設けたフック１７、１７に係止されているサイドストッパー５、５を取り外す。引き続いて、床部２の前枠挿入部６に嵌合された前枠１０の両支柱１１、１１を持ち上げて前枠１０を取り外す。
【００５４】
床部２上に取付部材１５を介して設けた前部ストッパー１３の鋸歯状部を外側に反転させる。（図９）
所望の順序にてガラス板Ｇを前部側より順次抜き取り、ガラス板Ｇの抜き取り作業が完了後は、仕切部材３３を係止部材３５より外し、仕切部材３３は背枠２０側で束ねておき、係止部材３５は折り畳んで床部２の長尺部材３、３間に収納する。
【００５５】
最後に、前枠１０を前記床部２の前枠挿入部６内に挿入嵌合して、固定し、サイドストッパー５を前枠１０の支柱１１にセットする。
【００５６】
【発明の効果】
本発明によれば、パレット上に積載された異なる寸法のガラス板を所望の順序で積み降ろしでき、積載するガラス板のサイズが異なっても、ガラス板の前部側の縦辺を前部ストッパー及び前部押圧具に当接させ、後部側の縦辺をガラス板１枚毎に後部押圧手段によって押さえてガラス板を挟持させ、確実にガラス板を固定させることができるので、長距離の輸送にも対応ができ、安全である。
【００５７】
また、該後部押圧手段の押え部材は、前後方向、上下方向にワンタッチで移動調節可能あるので、ガラス板の寸法の変化に容易に対応できる。
【００５８】
さらに、ガラス板間に仕切り手段によって、略対角線状に仕切部材を設けたので、隣接するガラス板同士の接触や、ガラス板の転倒を防ぐことができる。
【００５９】
さらにまた、ガラス板を前枠側に揃えて積載させるので、パレット上に積載されたガラス板より所望の位置のガラス板を取り出すときに、背枠基準に積載したものと比べて大幅に取り出しが簡単であり、作業効率がよい。

BACKGROUND OF THE INVENTION
The present invention relates to a glass plate transportation pallet that can be loaded and unloaded in a desired order without generating waste such as packaging sub-materials.
[0002]
[Prior art]
Conventionally, when transporting and transporting a plate-like body such as a glass plate, a large number of sheets are stacked and transported on a pallet, and various devices have been devised to prevent the collapse and falling of the material during transportation.
[0003]
In addition, when a glass plate is placed on the back side of the pallet and loaded, a cushioning material such as a slip sheet is required between the glass plates. In order to prevent scratches caused by contact between the glass plates due to misalignment or the like, means such as fixing the glass plate to the back frame of the pallet with a belt-like PP band made of polypropylene resin or the like is often performed.
[0004]
However, since these packaging sub-materials cannot be used repeatedly, there is a problem in that they become industrial waste and are expensive to dispose of.
[0005]
For example, in Japanese Patent Application Laid-Open No. 11-43187 related to the application by the present applicant, the pallet is repeatedly stacked so that the industrial waste is eliminated without using these auxiliary materials and the pallet can be used repeatedly. In the method of fixing multiple plate-like bodies to the back plate side of the pallet, a non-stretchable material band and a stretchable material band that are adjustable in length by a length adjuster are connected via a connector. , One end of the non-stretchable band is fixed to the back plate side of the pallet, and one of the connecting portions is connected by a detachable connecting tool, and at least one of the bands in the vertical direction and / or the horizontal direction is connected. There has been disclosed a method of fixing a plate-like body that is provided as described above and loaded on a pallet that suppresses the tilting of a plurality of plate-like bodies.
[0006]
Also, Japanese Patent Application Laid-Open No. 11-91944, which is also filed by the present applicant, is a transport carriage that loads glass plates separately in a vertical position one by one, and the loading direction of the glass plates on the bottom plate. A plurality of long members are juxtaposed in parallel, a vertical frame is erected above the vicinity of the corner of the bottom plate, and a horizontal frame is provided to connect the upper portions of the vertical frames. An auxiliary frame provided with a plurality of through holes in a direction orthogonal to the longitudinal direction of the length member is detachably provided, and a plurality of rods standing upward are embedded in each of the plurality of recesses provided in the length member. The glass provided with a rotating roller that slides and rotates when the glass plate is loaded and unloaded into the lower beam of the glass plate that is inserted into the through-hole and separated from each other by the rod. A board loading carriage is disclosed.
[0007]
In addition to the above examples, a glass spacing holding concave material made of hard resin and having a V-groove shape is arranged on the floor and the back frame side, and the glass plate is held by two sides of the vertical side and the bottom side of the back side. At the same time, pull out the rubber band attached to the upper side of the back frame, fix it to the front frame side floor of the glass plate, hold the glass plate by pressing the corner of the glass plate with an L-shaped fitting provided in the middle of the rubber band. A fixed pallet is used.
[0008]
[Problems to be solved by the invention]
The one described in Japanese Patent Application Laid-Open No. 11-43187 is loaded and packed in a stacked state from the back side of the pallet to the near side of the pallet, so the loading order is often loaded from a large size to a small size, In this case, it must be taken out from the small size loaded on the front side.
[0009]
In addition, when the glass plates loaded in this way are shipped to the user, they are not necessarily loaded in accordance with the order required by the user side, so that the order desired by the user is obtained. It is not easy in such a package to take out the glass plate that has been cut out.
[0010]
In addition, the one described in JP-A-11-91944 is a carriage that is useful for carrying in the field, although the various glass plates loaded are separated by rods and the desired glass plates can be loaded and unloaded. Therefore, there is no means for fixing both vertical sides of the glass plate, and long distance transportation by a truck or the like is not possible.
[0011]
Furthermore, the glass plate is held in contact with the floor portion and the back frame side, and the glass gap holding concave material and the rubber band attached to the upper side of the back frame are used to fix the corner portion in front of the upper side of the glass plate. In the case of the pallet, since it is loaded on the back frame standard, it is not easy to take out the small glass plate sandwiched between the large glass plates, and the rubber band only presses the corner of the glass plate. Therefore, it cannot be said that the glass plates are sufficiently fixed during long-distance transportation, and the glass plates may come into contact with each other.
