Description

ガラス板梱包体Glass plate package
　本発明は、輸送中のガラス板の汚染や破損を防止するための、ガラス板梱包体の改良に関する。 The present invention relates to improvements in glass plate packaging to prevent contamination and breakage of glass plates during transportation.
　ディスプレイ用のガラス基板等に使用されるガラス板は、運搬の際、パレット上に積層され、積層されたガラス板の最前部に押さえ板が配置され、それらを結束ベルトで結束することにより、パレットごと梱包される。パレット上へのガラス板の積層形態としては、水平な床に載置したパレットに平積みする横置き形態や、略鉛直又は傾斜したパレットに立て掛けるように積み上げる縦置き形態が代表的であり、パレットに対するガラス板の載置及び搬出の容易性、パレット設置面積の効率等の点においては、縦置き形態が有利となる。 Glass plates used as glass substrates for displays are stacked on a pallet during transportation. A pressing plate is placed at the front of the stacked glass plates, and they are tied with a binding belt to secure the pallet. packed together. Typical examples of the stacking of glass sheets on a pallet include a horizontal layout in which glass sheets are laid flat on a pallet placed on a horizontal floor, and a vertical layout in which glass sheets are stacked so as to lean against a substantially vertical or inclined pallet. In terms of easiness of loading and unloading the glass sheet from the pallet, efficiency of the pallet installation area, and the like, the vertical installation form is advantageous.
　パレットに積載されたガラス板を輸送する際は、国際的な統一規格に基づいて製造された一般的なコンテナに収容する場合がある。また、近年、ディスプレイの製造工程の生産性を向上させる観点から、ガラス板の寸法は大きくなる傾向にある。このため、開口部の無いコンテナにはガラス板を収容することができず、上面に開口部が設けられた、オープントップコンテナ等の収容容器を用いた輸送が行われている。 　When transporting glass sheets loaded on pallets, they may be stored in general containers manufactured according to international unified standards. Further, in recent years, from the viewpoint of improving the productivity of the display manufacturing process, the size of the glass plate tends to increase. For this reason, the glass sheets cannot be accommodated in a container without an opening, and are transported using a container such as an open-top container having an opening on the top surface.
　パレットに積載されたガラス板をコンテナに収容して輸送する場合、大気中の浮遊物質によるガラス板の汚染を防ぐため、ガラス板やパレットをカバーで覆う必要がある。特許文献１には、ガラス板および保護シートが交互に積層されたガラス板積層体と、ガラス板積層体が積載されるパレットと、ガラス板積層体及びパレットを覆う袋と、を備えたガラス板梱包体が開示されている。 When storing and transporting glass sheets loaded on pallets in a container, it is necessary to cover the glass sheets and pallets to prevent contamination of the glass sheets by airborne substances. Patent Document 1 discloses a glass plate including a glass plate laminate in which glass plates and protective sheets are alternately laminated, a pallet on which the glass plate laminate is loaded, and a bag that covers the glass plate laminate and the pallet. A package is disclosed.

As a result, it is possible to prevent the hard cover 6 from being displaced in the Y direction even when vibration or impact is applied during transportation. Moreover, even when the number of glass plates G to be stacked is reduced, the hard cover 6 can cover the upper surface of the glass plate laminate 2 without falling. As a material for the hard cover 6, plastic corrugated cardboard, cardboard, polystyrene foam, or the like can be used. In this embodiment, a plastic cardboard with excellent durability is used. Moreover, it is preferable that the buffer sheet 5 does not protrude from the lower ends of the front surface portion 62 and the rear surface portion 63 of the hard cover 6 . This prevents the cushioning sheet 5 in contact with the soft cover 7 from shifting in the Y direction when the soft cover 7, which will be described later, is arranged or removed. The width dimension W6 of the hard cover 6 is larger than the width dimension WG of the glass plate G shown in FIG. As a result, the entire width direction (X direction) of the glass plate laminate 2 can be covered, so breakage of the glass plates can be more reliably prevented.

　第二実施形態は、ガラス板積層体２と、パレット３と、保護板４と、緩衝シート５の構成は第一実施形態と同一である。第一実施形態では、硬質カバー６及び軟質カバー７が複合体Ｍを覆っていたが、第二実施形態では、カバー９が複合体Ｍを覆っている。カバー９は、硬質部９１と、軟質部９２とを備える。 In the second embodiment, the configurations of the glass plate laminate 2, pallet 3, protection plate 4, and buffer sheet 5 are the same as in the first embodiment. While the hard cover 6 and the soft cover 7 cover the composite M in the first embodiment, the cover 9 covers the composite M in the second embodiment. The cover 9 has a hard portion 91 and a soft portion 92 .
　図１１に示すように、カバー９の硬質部９１は、ガラス板積層体２、保護板４、及び背面支持部３１から構成される複合体Ｍの上端部を覆う。硬質部９１と複合体Ｍの間には、緩衝シート５が介在する。硬質部９１は、第一実施形態の硬質カバー６と同一の構成である。 As shown in FIG. 11, the hard portion 91 of the cover 9 covers the upper end portion of the composite M composed of the glass plate laminate 2, the protective plate 4, and the back support portion 31. A buffer sheet 5 is interposed between the rigid portion 91 and the composite M. The hard portion 91 has the same configuration as the hard cover 6 of the first embodiment.
　カバー９の軟質部９２は、上端部が硬質部９１に取り付けられており、複合体Ｍのうち、硬質部９１に覆われる部分より下側の部分を覆うように配置される。軟質部９２の材質及び形状は、上端部が硬質部９１に取り付けられている点を除いて、第一実施形態の軟質カバー７と同様である。このように硬質部９１と軟質部９２とを備えるカバー９が複合体Ｍを覆うことにより、ガラス板梱包体１を梱包及び開梱する際の工数を削減することができる。 The soft portion 92 of the cover 9 has its upper end attached to the hard portion 91 and is arranged to cover the portion of the composite M below the portion covered by the hard portion 91 . The material and shape of the soft portion 92 are the same as those of the soft cover 7 of the first embodiment, except that the upper end is attached to the hard portion 91 . By covering the composite M with the cover 9 including the hard portion 91 and the soft portion 92 in this way, the number of man-hours for packing and unpacking the glass plate package 1 can be reduced.
　以上のようなガラス板梱包体によれば、複合体Ｍに含まれるガラス板積層体２が軟質カバー７（カバー９）で覆われているため、ガラス板Ｇの汚染を防止することができる。この効果は、大型のガラス板Ｇを積載したガラス板梱包体を輸送する際に、オープントップコンテナ等の収容容器８に収容した場合に、特に顕著となる。また、硬質カバー６（硬質部９１）により、軟質カバー７（軟質部９２）の荷重や、梱包作業時や輸送時にガラス板積層体２の上端部に加わる衝撃を、硬質カバー６（硬質部９１）を介して保護板４及び背面支持部３１に効率よく分散できる。その結果、ガラス板Ｇの破損を防止することができる。 According to the glass plate package as described above, since the glass plate laminate 2 included in the composite M is covered with the soft cover 7 (cover 9), the glass plates G can be prevented from being contaminated. This effect is particularly remarkable when a glass plate package loaded with large glass plates G is stored in a storage container 8 such as an open top container when transporting the glass plate package. In addition, the hard cover 6 (hard portion 91) prevents the load of the soft cover 7 (soft portion 92) and the impact applied to the upper end portion of the glass plate laminate 2 during packing and transportation. ) to the protective plate 4 and the back support portion 31 efficiently. As a result, breakage of the glass plate G can be prevented.
　また、緩衝シート５を介して硬質カバー６（硬質部９１）を配置することにより、輸送時の振動や衝撃が緩衝シート５によって吸収され、より確実にガラス板Ｇの破損を防止することができる。 In addition, by arranging the hard cover 6 (hard portion 91) through the buffer sheet 5, vibrations and shocks during transportation are absorbed by the buffer sheet 5, and breakage of the glass plate G can be prevented more reliably. .
