Description

【発明の属する技術分野】
本発明は、例えば大画面液晶TVの前面に装着するアクリル製湾曲板のように、所定の大きさの湾曲板を多数枚積み重ねて搬送する際に使用する紙製のパレットに関する。
【0002】
【従来の技術】
従来から、例えば特許文献1に記載されるような、段ボール板からなる紙製パレットが知られている。
このような紙製のパレットは、旧来の木製パレットや合成樹脂製パレットに比べて軽量で輸送コストが安く、リサイクル性に優れるなどの各種利点を有するものの、上面が水平な載承面であるため、大画面液晶TVの前面に装着するアクリル製湾曲板のように、所定の大きさの湾曲板を複数枚積み重ねて搬送する場合には不向きであった。
【0003】
【特許文献1】
特開2000−335579号公報
【0004】
一方、例えば画像を投影する映写スクリーンやロール製品のような湾曲面を有する製品(被搬送物)を搬送するための紙製パレットとして、特許文献2のように、上端面を曲面にカットした桁材を、間隔をおいて平行に必要数配列したダンボール製パレットや、特許文献3のように、縦桁と横桁を互いに交叉する井桁状に組合わせると共にそれら縦桁と横桁を表皮シートでカバーした搬送用パレットが提案されている。

【0006】
【発明が解決しようとする課題】
特許文献2に記載されたダンボール製パレットは、製品の載承面を、各桁材(横桁)の上端面のみから形成するようになっており、多数の桁材を必要とするばかりか、これら多数の桁材を、若干の隙間を残して平行に並べた一体成形物のような構造になるので、材料の無駄が生じるという問題がある。
特許文献3に記載された搬送用パレットは、複数の横桁と縦桁を組合わせることで特許文献2による問題は解消できるが、縦桁相互間、横桁相互間に空間部分が形成されるので、この部分の支持強度が弱くなり、大画面液晶TVの前面に装着するアクリル製湾曲板のような製品を多数枚積み重ねた場合、積載荷重の分散が不均一になって製品にうねり状(波状)の変形が生じる虞れがある。
【0007】
本発明はこのような従来事情に鑑みてなされたもので、その目的とするところは、大画面液晶TVの前面に装着するアクリル製湾曲板のような、積載荷重分布が不均一になるとうねり状の変形が生じ易い製品を搬送するための紙製パレットであって、前記うねり状の変形が生じることのないよう、積載荷重が均一に分散される状態で前記湾曲板のような製品を多数枚積み重ねて搬送することができ、且つ材料の無駄なく形成される新規な紙製パレットを提供することにある。
【0008】
【課題を解決するための手段】
以上の目的を達成するために、本発明の紙製パレットは請求項1記載のように、比較的大型の湾曲板を搬送するための紙製パレットであって、
左右の縦桁(1,1)の間に中央の縦桁(2)を配列し、且つ前記左右の縦桁の間に所定間隔をおいて複数の横桁(3)を平行に配列すると共に、前記左右の縦桁(1,1)、中央の縦桁(2)、複数の横桁(3)で区画形成される複数の空間部(4)にX字形桟(5)を各々装填し、さらに前記湾曲板と同様な湾曲形状の上面板(6)を固着して該上面板(6)を前記左右及び中央の縦桁(1,1,2)、複数の横桁(3)とX字形桟(5)で支持してなり、
前記横桁の上端面(3a)とX字形桟の上端面(5a)は前記湾曲板の曲率に合う曲面状にカットされ、前記左右の縦桁(1,1)と中央の縦桁(2)は各々前記湾曲板の曲率に合わせた高さに形成されていることを特徴とする。
【0009】
このように形成した場合、左右及び中央の縦桁(1,1,2)と、複数の横桁(3)を組み合わせると共に、それら各桁間に区画形成される空間部(4)にX字形桟(5)を装填したパレット本体(a)に上面板(6)を固着した構造になるので、その上面板(6)上に多数枚積み重ねた湾曲板(被搬送物)の積載荷重を、夫々の縦桁(1,1,2)、横桁(3)及びX字形桟(5)により均等に分散させることができる。
【0010】
また本発明の請求項2では、前記左右及び中央の縦桁(1,1,2)、複数の横桁(3)とX字形桟(5)が、上面を開口する外ケース(7)内に収容されていることを特徴とする。
【0011】
このように形成した場合、左右及び中央の縦桁(1,1,2)と複数の横桁(3)及びX字形桟(5)からなるパレット本体(a)をユニット化することができ、耐久性の向上を図れると共に、作製がより容易になるなどの利点がある。
【0012】
請求項3では、前記外ケース(7)が、側周壁にフォーク差し込み用開口(8)を有する下部パレット(b)の上面に固着されていることを特徴とする。
【0013】
このように形成した場合、フォーク差し込み用開口(8)を有する下部パレット(b)を一体に備えた紙製パレットとなるので、フォークリフトを用いて、搬送作業を容易に行えるようになる。
【0014】
本発明に係る紙製パレットは、請求項4のように、左右及び中央の縦桁(1,1,2)、複数の横桁(3)とX字形桟(5)、上面板(6)、外ケース(7)、下部パレット(b)を、単層段ボール板又は2層以上の多層段ボール板からなるものとすることが、作製コストの低減、耐久性や強度の向上、リサイクル性などの点で好ましい。
【0015】
また本発明に係る紙製パレットは、請求項5のように、大画面液晶TVの前面に装着するアクリル製湾曲板を多数枚積層して搬送する場合に好適に用いることができる。
【0016】
【発明の実施の形態】
以下、本発明に係る紙製パレットの実施形態の一例を図1〜図5を参照して説明する。本例の紙製パレットAは図1に示すように、下部パレットbの上面に外ケース7を固着すると共に、その外ケース7内に、左右の縦桁1,1、中央の縦桁2、複数の横桁3、複数のX字形桟5からなるパレット基体部aを収容し、かつそのパレット基体部aに上面板6を固着してなり、図5に示すように、大画面液晶TVの前面に装着するアクリル製の湾曲板100を多数枚積み重ねた状態で、その湾曲板100がうねり状に変形するような虞れなく積載して搬送し得るよう形成されている。
【0017】
下部パレットbは、例えば特開2000−335579号公報に記載されるような段ボール板からなる従来公知の紙製パレットであって、その側周四面に、フォーク差し込み用の開口8を備えると共に、上面にデッキボード9を固着して形成されている。
【0018】
外ケース7は、段ボール板からなる基材の要所の折り曲げと貼り着けにより、上面が開口する四角形の箱状に形成されている。
【0019】
左右の縦桁1,1は、段ボール板からなる基材の要所の折り曲げと貼り着けにより、図3中に示すような多層構造の桁材として形成され、その上端面には、横桁3の左右端部の下向き切込み31が嵌り込む上向き切込み11が、縦桁1の長手方向に対し適宜間隔ごとに形成されている。また左右の縦桁1,1は、上面板6の(湾曲板100の)曲率に合わせて適宜高さに(中央の縦桁2よりも高く)形成されており、外ケース7の内部空間の左右両側に起立状に配列され、該外ケース7の底面板7aに固着されている。
【0020】
中央の縦桁2は、段ボール板からなる基材を複数枚貼り着けることにより、図3中に示すような多層構造の桁材として形成され、その上端面には、横桁3の中央の下向き切込み32が嵌り込む上向き切込み21が、縦桁2の長手方向に対し適宜間隔ごとに形成されている。また中央の縦桁2は、上面板6の(湾曲板100の)曲率に合わせて適宜高さに(左右の縦桁1,1よりも低く)形成されており、外ケース7の内部空間のほぼ中央に起立状に配列され、該外ケース7の底面板7aに固着されている。
【0021】
夫々の横桁3は、段ボール板からなる基材を複数枚貼り着けることにより、図3中に示すような多層構造の桁材として形成され、その下端面には、縦桁1の上向き切込み11に嵌り込む下向き切込み31が左右端部に形成されると共に、縦桁2の上向き切込み21に嵌り込む下向き切込み32が中央に形成されており、それら下向き切込み31,32が対応する上向き切込み11,21に嵌り込む状態で、左右の縦桁1,1にわたって配列されている。
また夫々の横桁3の上端面3aは、上面板6の(湾曲板100の)曲率に合わせて曲面状にカットされている。
【0022】
このようにして枠組みされた左右の縦桁1,1、中央の縦桁2、複数の横桁3の間には、複数の空間部4が区画形成されるが、夫々の空間部4には、図2に示すように、X字形桟5が装填されている。
【0023】
X字形桟5は、図4に示すように段ボール板からなる二枚の基材5-1,5-2からなるもので、一方の基材5-1の下端面に設けた下向き切込み51と他方の基材5-2の上端面に設けた上向き切込み52を係合させてX字形に形成されている。それら基材5-1,5-2の上端面5aは湾曲板100の曲率に合う曲面状にカットされており、その上端面5aの曲率が湾曲板100の曲率に合うよう配列する状態で前記空間部4に装填され、外ケース7の底面板7aに固着されている。
【0024】
上面板6は、湾曲板100と同様な湾曲形状の段ボール板からなり、前記した左右及び中央の縦桁1,1,2と複数の横桁3及びX字形桟5とで構成されるパレット本体aの上面、すなわち、左右及び中央の縦桁1,1,2と複数の横桁3及びX字形桟5の上端面1a,1a,2a,3a,5a上に固着されて、それら縦桁1,2、複数の横桁3及びX字形桟5で支持されている。
【0025】
前記した縦桁1,2、横桁3、X字形桟5、上面板6、外ケース7、下部パレットb、デッキボード9などの各構成要素は、単層段ボールや2層以上の多層段ボールからなる段ボール板を単独で又はそれらを必要数貼り合わせることで、所望の強度と耐久性を備えるよう形成されている。
【0026】
以上の構成になる本例の紙製パレットAは、図5に示すように、上面板6上に多数枚積み重ねた被搬送物としての湾曲板100の積載荷重を、左右の縦桁1,1、中央の縦桁2、複数の横桁3、複数のX字形桟5により均等に分散させることができる。よって、被搬送物が大画面液晶TVの前面に装着するアクリル製の湾曲板100であって、多数枚積み重ねた場合にその荷重によりうねり状に変形が生じる虞れのある製品を、変形が生じることなく積載して搬送することができる。
【0027】
また、左右の縦桁1,1、中央の縦桁2、複数の横桁3、複数のX字形桟5からなるパレット本体aを外ケース7内に収容することでパレット本体aをユニット化することができ、パレット本体aの強度や耐久性が向上すると共に、その作製が容易になるなどの利点がある。
【0028】
また、フォーク差し込み用開口8を有する下部パレットbを一体に備えているので、フォークリフトを用いて搬送作業を容易に行うことができる。
【0029】
また前記したように、各縦桁1,2、横桁3、X字形桟5、上面板6、外ケース7、下部パレットb、デッキボード9などの各構成要素を段ボール板製としたので、作製コストの低減、耐久性や強度の向上、リサイクル性などの点で多くの効果を奏する。
【0030】
【実施例】
2層の段ボール板を用いて、長さ900mm,高さ110mm程度の左右の縦桁1と、長さ900mm,高さ70mm程度の中央の縦桁2と、長さ700mm,左右端部の高さ120mm,中央部の高さ70mm程度の横桁3と、長さ350mm,内端部の高さ70mm,外端部の高さ110mm程度の二枚の基材5-1,5-2からなるX字形桟5を、900mm×700mm程度の大きさの外ケース7内で組み合わせてパレット本体aを形成すると共に、該パレット本体aの上面に、外ケース7と同程度の大きさで且つ湾曲板100と同じ曲率で湾曲する上面板6を固着し、さらに外ケース7を下部パレットbのデッキボード9上に載置し、且つそれら各構成要素同士の所要箇所を所望の接着剤で固着して紙製パレットAを作製した。
この紙製パレットAの上面板6上に、大画面液晶TVの前面に装着するアクリル製湾曲板100を20枚程積み重ねて積載し所定時間静置したところ、各湾曲板100にはうねり状の変形が生じることなく、フォークリフトを用いて安定した状態で搬送することができた。
【0031】
以上、本発明の実施形態の一例を図面を参照しながら説明したが、本発明に係る紙製パレットの構成や用途は図示例のものに限られず、特許請求の範囲の各請求項に記載された技術的思想の範疇において、種々の変更が可能であることは言うまでもない。
【0032】
【発明の効果】
本発明は以上説明したように、段ボール板などの板紙からなる紙製のパレットであるから、木材や合成樹脂等からなるパレットに比べて材料費が安く、製作性も良く、かつ軽量であるため取り扱いやすく、さらにはリサイクル性にも適したものである。
また、左右及び中央の縦桁と複数の横桁との間に形成される空間部分に、X字形の桟を装填して、製品(被搬送物)に係る積載荷重が均一に分散される構成としたので、紙材を効率良く用いながら、製品にかかる荷重を均一に分散して支持することができる。したがって、大画面液晶TVの前面に装着するアクリル製湾曲板のように、積載荷重分布が不均一になるとうねり状の変形が生じ易い製品を、そのような変形が生じることなく多数枚を積み重ねて搬送することができ、且つ材料の無駄無く低コストでの製造が可能な、新規な紙製パレットを提供することができた。

[Problems to be solved by the invention]
The corrugated cardboard pallet described in Patent Document 2 is designed to form the product bearing surface only from the upper end surface of each girder (horizontal girder), and not only requires a large number of girder materials, Since such a large number of girders have a structure like an integrally molded product in which a few gaps are arranged in parallel, there is a problem that material is wasted.
The pallet for conveyance described in Patent Document 3 can solve the problem caused by Patent Document 2 by combining a plurality of horizontal beams and vertical beams, but a space portion is formed between the vertical beams and between the horizontal beams.

Further, the pallet body a is unitized by housing the pallet main body a composed of the left and right vertical girders 1, 1, the central vertical girder 2, the plurality of horizontal girders 3, and the plurality of X-shaped bars 5 in the outer case 7. This is advantageous in that the strength and durability of the pallet main body a are improved and the manufacture thereof is facilitated.
[0028]
In addition, since the lower pallet b having the fork insertion opening 8 is integrally provided, the conveyance work can be easily performed using a forklift.
[0029]
Further, as described above, the respective structural elements such as the vertical beams 1, 2, the horizontal beam 3, the X-shaped beam 5, the upper surface plate 6, the outer case 7, the lower pallet b, and the deck board 9 are made of corrugated board, There are many effects in terms of reduction in production cost, improvement in durability and strength, recyclability, and the like.
[0030]
【Example】
Using a two-layer corrugated board, left and right stringers 1 with a length of about 900 mm and a height of about 110 mm, a center stringer 2 with a length of about 900 mm and a height of about 70 mm, a length of 700 mm and the height of the left and right ends From the two bases 5-1 and 5-2 having a length of 120 mm, a central beam 3 having a height of about 70 mm, and a length of 350 mm, a height of the inner end of 70 mm, and a height of the outer end of about 110 mm. The X-shaped crosspiece 5 is combined in an outer case 7 having a size of about 900 mm × 700 mm to form a pallet main body a, and the upper surface of the pallet main body a has the same size as the outer case 7 and is curved. The upper surface plate 6 that is curved with the same curvature as the plate 100 is fixed, and the outer case 7 is further placed on the deck board 9 of the lower pallet b, and the required portions of these components are fixed with a desired adhesive. A paper pallet A was prepared.
On the upper surface plate 6 of the paper pallet A, about 20 acrylic curved plates 100 to be mounted on the front surface of the large-screen liquid crystal TV were stacked and allowed to stand for a predetermined time. Without deformation, the forklift could be used to transport in a stable state.
[0031]
The embodiment of the present invention has been described above with reference to the drawings. However, the configuration and application of the paper pallet according to the present invention are not limited to the illustrated examples, and are described in the claims. It goes without saying that various modifications are possible within the scope of the technical idea.
[0032]
【The invention's effect】
As described above, the present invention is a paper pallet made of paperboard such as corrugated board, and therefore has lower material costs, better manufacturability, and lighter weight than a pallet made of wood or synthetic resin. It is easy to handle and also suitable for recyclability.
In addition, the space formed between the left and right and center vertical beams and a plurality of horizontal beams is loaded with an X-shaped beam so that the load on the product (conveyed object) is evenly distributed. Therefore, the load applied to the product can be uniformly dispersed and supported while using the paper material efficiently. Therefore, products such as an acrylic curved plate mounted on the front of a large-screen liquid crystal TV that are prone to undulating deformation when the load distribution is uneven are stacked without causing such deformation. It was possible to provide a new paper pallet that can be transported and can be manufactured at low cost without wasting material.
