Description

本発明は、複数枚のガラス板を重ねて梱包する際のガラス板の破損を防ぐためのスペーサーに関する。   The present invention relates to a spacer for preventing breakage of a glass plate when a plurality of glass plates are stacked and packed.

大型で厚板のガラス板、例えば、建築用板ガラスや自動車用フロントガラス用の合せガラス等は、工場等から出荷搬送する場合、パレット上に多数並列して縦置きして梱包している。  Large, thick glass plates, such as architectural flat glass and laminated glass for automobile windshields, are shipped and transported from factories or the like in large numbers in parallel on a pallet and packed vertically.

パレット上に複数枚縦積みされたガラス板は、輸送時の振動によるガラス板の摺り傷防止又はガラス板面に突起した部材を装着した場合はその突起物の損傷防止等の目的で１枚毎に間隔を保持して固定しておく必要がある。   Plural glass plates stacked vertically on a pallet are used to prevent scratching of the glass plate due to vibration during transportation or to prevent damage to the protrusions when a member protruding from the glass plate is attached. It is necessary to keep a fixed distance between them.

そのためには、ガラス板間に介在部材を介在させてガラス板１枚毎に間隔を保持して固定しておくための間隔保持具（スペーサー）が提案されている（特許文献１〜５）。   To this end, there has been proposed an interval holder (spacer) for interposing an intervening member between the glass plates to hold and fix the interval for each glass plate (Patent Documents 1 to 5).

例えば、特許文献１には、湾曲したガラス板の場合、プラスチック製介在部材（仕切部片）がガラス板の曲面に沿って変形しガラス板の一部に集中荷重がかからないようにしたガラス板間隔保持具として、ガラス板に当接する複数の当接片を屈曲可能な連結部材で連結し、そうして構成された湾曲可能な介在部材（仕切部片）２個をほぼガラス板の厚さに相当する所定の間隔だけ離して上部を連結し、ガラス板を挟み込むようにクリップ型に構成されたガラス板間隔保持具が開示されている。   For example, in Patent Document 1, in the case of a curved glass plate, a glass intervening member (partition piece) is deformed along a curved surface of the glass plate so that a concentrated load is not applied to a part of the glass plate. As a holder, a plurality of abutting pieces abutting on the glass plate are connected by a bendable connecting member, and the two bendable intervening members (partition pieces) configured as described above are reduced to approximately the thickness of the glass plate. There is disclosed a glass plate interval holding member which is configured in a clip shape so as to connect the upper portions with a predetermined distance therebetween and sandwich the glass plate.

また、特許文献２には、ガラス板主面の周縁部で、端面付近の領域には、スペーサーがガラス板主面に接触しないような構造のプラスチック製クリップ型スペーサーが開示されている。ガラス板主面の周縁部の端面付近の領域は、ガラス板を車両等の窓枠に装着するときには、接着用プライマーが塗布される。特許文献２で開示されたスペーサーを使用した場合、前記領域に、スペーサーの連結薄片が接触することはないが仕切部片がガラス板に密接する。   Further, Patent Document 2 discloses a plastic clip-type spacer having a structure in which a spacer does not contact the glass plate main surface in a region near an end surface at a peripheral portion of the glass plate main surface. When the glass plate is mounted on a window frame of a vehicle or the like, an adhesive primer is applied to a region near an end surface of a peripheral portion of the glass plate main surface. When the spacer disclosed in Patent Literature 2 is used, the connecting thin piece of the spacer does not come into contact with the region, but the partition piece comes into close contact with the glass plate.

実開昭５６−１４８８８号公報Japanese Utility Model Publication No. 56-14888 特開平８−２３０９６４号公報JP-A-8-230964 特開平１０−１３９１６２号公報JP-A-10-139162 特開平２００２−３７３７２号公報JP-A-2002-37372 特開平２００２−３７３７４号公報JP-A-2002-37374

複数枚のガラス板をパレット上に複数枚縦積みして積載するときの間隔保持部材として、プラスチック製のクリップ型スペーサーは、ガラス板表面の損傷を防ぐために有用である。しかしながら、スペーサーの仕切部片がガラス板に接触していた領域においては、プラスチック材料に起因したガラス板表面の汚染が生じることがある（この汚染を、以降、「接触跡」と表記する）。接触跡は、時には目視で観測されることがあるので、搬送された大量のガラス板に接触跡が観測されることになると、接触跡の除去を行うための追加工程が必要となりコストがかかることがあった。   As a spacing member when a plurality of glass plates are stacked vertically on a pallet, a clip-type spacer made of plastic is useful for preventing the surface of the glass plate from being damaged. However, in the region where the partitioning piece of the spacer was in contact with the glass plate, the surface of the glass plate may be contaminated by the plastic material (this contamination is hereinafter referred to as "contact mark"). Contact traces are sometimes observed visually, so if contact traces are observed on a large number of glass plates transported, an additional process for removing the contact traces will be required and costly was there.

本発明は、ガラス板に目視で観測される接触跡が生じにくいガラス板梱包用スペーサーを提供することを課題とする。   An object of the present invention is to provide a glass plate packing spacer in which a contact mark visually observed on a glass plate is less likely to occur.

本発明は、上述した問題点を解決するためになされたものである。
すなわち、本発明は、（１）パレットの内底部に下縁を固定され複数枚縦積みされたガラス板群における、各ガラス板の上縁に係止するための頭部片と、頭部片の下側に形成された仕切部片を有するプラスチック製スペーサー本体部と、前記仕切部片とガラス板主面との間に介在させる布体とからなることを特徴とするガラス板梱包用スペーサーである。
また、本発明は、（２）前記布体が、スペーサー本体部を覆う態様になる大きさ及び形状の袋状の布体であることを特徴とする（１）に記載のガラス板梱包用スペーサーである。
また、本発明のスペーサーは、（３）前記袋状の布体の開口部周縁は、ゴム等の弾性を有する紐状物を備えていることを特徴とする（２）に記載のガラス板梱包用スペーサー。
また、本発明は、（４）前記布体の組織が、織物、編み物（メリヤス生地）、レース、フェルト、不織布の何れかからなることを特徴とする（１）〜（３）に記載のガラス板梱包用スペーサーである。
さらに、本発明は、（５）（１）〜（４）のいずれかに記載のスペーサーを用いることを特徴とする曲面形状の自動車用窓ガラス板の梱包方法である。 The present invention has been made to solve the above problems.
That is, the present invention provides (1) a head piece for locking to an upper edge of each glass plate in a plurality of vertically stacked glass plates having a lower edge fixed to an inner bottom portion of a pallet; A glass spacer packing spacer comprising a plastic spacer body having a partition piece formed on the lower side thereof, and a cloth interposed between the partition piece and the glass plate main surface. is there.
Further, in the present invention, (2) the spacer for packing a glass plate according to (1), wherein the cloth body is a bag-shaped cloth body having a size and a shape that covers the spacer body. It is.
In the spacer of the present invention, (3) the glass plate package according to (2), wherein the periphery of the opening of the bag-shaped cloth body is provided with an elastic string such as rubber. Spacer.

Further, the present invention provides a method for packing a curved window glass plate for an automobile, wherein the spacer according to any one of (5), (1) to (4) is used.

本発明のスペーサーは、ガラス板に目視で観測される接触跡が生じにくいので、搬送後のガラス板の外観品質の向上に奏功し、仕切部片とガラス板主面との間の緩衝性も向上する。また、既存のスペーサーを、本発明のスペーサーの構造に使用することもできるので、資源の有効活用にも有用であるし、仕切部片とガラス板主面との間の緩衝性も向上する。   Since the spacer of the present invention hardly causes a contact mark visually observed on the glass plate, it is effective in improving the appearance quality of the glass plate after being conveyed, and also has a cushioning property between the partition piece and the main surface of the glass plate. improves. In addition, since the existing spacer can be used for the structure of the spacer of the present invention, it is useful for effective use of resources, and the buffering property between the partition piece and the main surface of the glass plate is improved.

以下、図面を参照して、本発明の実施形態について説明する。
１．スペーサー本体部について
スペーサー本体部４’の素材はプラスチック製である。例えば、ポリエチレン樹脂、ポリプロピレン樹脂、ポリエステル樹脂、ポリアミド樹脂、ポリ塩化ビニル樹脂、ポリスチレン樹脂、酢酸ビニル樹脂、アクリル樹脂、ＡＢＳ樹脂等を挙げることができる。中でも、ポリエチレン樹脂及びＡＢＳ樹脂が樹脂の価格、成型のし易さ及び耐久性の面から好ましい。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1. Regarding the spacer main body The material of the spacer main body 4 'is made of plastic. For example, polyethylene resin, polypropylene resin, polyester resin, polyamide resin, polyvinyl chloride resin, polystyrene resin, vinyl acetate resin, acrylic resin, ABS resin, and the like can be given. Among them, polyethylene resin and ABS resin are preferable from the viewpoint of resin price, ease of molding, and durability.

スペーサーの本体部４’の形状例として、図２で示すようなガラス板３の端面に接触する頭部片８と、ガラス板３の端面から０〜５０ｍｍ程度の所定距離離隔してガラス板３主面の両面に布体１１を介して密接する一対の仕切部片９と、頭部片８と仕切部片９を接続しガラス板３の主面に接触しない一対の連結薄片１０とからなるクリップ型の形状を挙げることができる。   As an example of the shape of the main body portion 4 ′ of the spacer, a head piece 8 that contacts the end face of the glass plate 3 as shown in FIG. 2 and a glass plate 3 that is separated from the end face of the glass plate 3 by a predetermined distance of about 0 to 50 mm. It consists of a pair of partition pieces 9 that are in close contact with both sides of the main surface via a cloth body 11, and a pair of connecting thin pieces 10 that connect the head piece 8 and the partition piece 9 and do not contact the main surface of the glass plate 3. Clip-shaped shapes can be mentioned.

仕切部片９が布体１１を介して密接する位置を、ガラス板３の端面から大きく離すほど、当該形状のスペーサー本体部４’とガラス板３主面の間に介在する布体１１を有するスペーサー４を装着した領域のガラス板３周縁部が破損しやすくなる。これは、ガラス板３端面部近傍にガラス板３主面に直交する方向に応力がかかった場合、仕切片９が布体１１を介して接触した部分に大きな応力が集中するためである。ガラス板３主面の周縁部の端面付近の領域は、ガラス板３を車両等の窓枠に装着するときには、接着用プライマーが塗布される。本来、仕切部片９を頭部片８から所定距離離隔する目的は、仕切部片９の接触跡に起因するプライマーはじきを避けるためであった。しかし、当該形状のスペーサー本体部４’とガラス板３主面の間に介在する布体１１を有するスペーサー４では、前記接触跡を目視確認されないことから、仕切部片９をガラス板３の端面から隔離しなくてもよい場合もある。   The farther the position where the partitioning piece 9 comes into close contact with the cloth body 11 from the end face of the glass plate 3, the more the cloth body 11 interposed between the spacer main body portion 4 ′ and the main surface of the glass plate 3 is provided. The periphery of the glass plate 3 in the region where the spacer 4 is mounted is easily damaged. This is because, when a stress is applied to the vicinity of the end surface of the glass plate 3 in a direction orthogonal to the main surface of the glass plate 3, a large stress is concentrated on a portion where the partition piece 9 contacts via the cloth body 11. When attaching the glass plate 3 to a window frame of a vehicle or the like, an adhesive primer is applied to a region near the end surface of the peripheral portion of the main surface of the glass plate 3. Originally, the purpose of separating the partition piece 9 from the head piece 8 by a predetermined distance was to avoid repelling of the primer caused by the contact trace of the partition piece 9. However, in the spacer 4 having the cloth body 11 interposed between the spacer main body portion 4 ′ and the main surface of the glass plate 3 of the shape, since the contact trace is not visually confirmed, the partition piece 9 is attached to the end surface of the glass plate 3. In some cases, it may not be necessary to isolate them.

そして、該形状において、一対の連結薄片１０の間の距離は、ガラス板３の厚みより大きくなるようにする。当該形状のスペーサー本体部４’とガラス板３主面の間に介在する布体１１を有するスペーサー４は、こうすることによりガラス板３周縁部に挟み込んだときに、連結薄片１０がガラス板３主面に接触するのを防ぐことができる。
一対の連結薄片１０の下側に接続する仕切部片９間の距離は、ガラス板３の厚みと同じ程度である方が好ましいが、ガラス板３の厚みと異なっていても、スペーサーの素材がプラスチック製であることと連結薄片１０が薄片であることから、連結薄片１０が容易に変形するために、スペーサー４をガラス板３周縁部に挟み込むことができ、仕切部片９を布体１１を介してガラス板３種面に密着することができる。 In the shape, the distance between the pair of connecting thin pieces 10 is set to be larger than the thickness of the glass plate 3. The spacer 4 having the cloth body 11 interposed between the spacer main body portion 4 ′ and the main surface of the glass plate 3 having such a shape allows the connecting thin piece 10 to be connected to the glass plate 3 when the spacer 4 is sandwiched between the peripheral edges of the glass plate 3. Contact with the main surface can be prevented.
It is preferable that the distance between the partition pieces 9 connected to the lower side of the pair of connecting thin pieces 10 is approximately the same as the thickness of the glass plate 3. Since the connecting piece 10 is made of plastic and the connecting piece 10 is a thin piece, the connecting piece 10 can be easily deformed, so that the spacer 4 can be sandwiched between the peripheral edges of the glass plate 3, and the partitioning piece 9 can be attached to the cloth body 11. Can be in close contact with the three types of glass plates.

本発明のスペーサーは、自動車用フロント／リア窓ガラス板３の積載に用いられることが多い。ガラス板３主面は、通常、曲面形状になっており仕切部片９は、ガラス板３主面に接触した際、ガラス板３主面の曲面に沿って曲がるものが好ましい。そのため、スペーサーの本体部４’の仕切部片９は、図２に示すとおり、薄手の可撓性基部９’に厚手の突出部９”を適宜複数配設してなるものとすることが好ましい。一対の連結薄片１０の厚みは、１〜３ｍｍ程度、薄手の可撓性基部９’の厚みは１〜３ｍｍ程度、厚手の突出部９” の厚みは ５〜１０ｍｍ程度とすればよい。  The spacer of the present invention is often used for loading the front / rear window glass plate 3 for automobiles. The main surface of the glass plate 3 is usually curved, and the partition piece 9 preferably bends along the curved surface of the main surface of the glass plate 3 when it comes into contact with the main surface of the glass plate 3. For this reason, as shown in FIG. 2, it is preferable that the partition piece 9 of the main body portion 4 ′ of the spacer is formed by appropriately arranging a plurality of thick protrusions 9 ″ on a thin flexible base 9 ′. The thickness of the pair of connecting thin pieces 10 may be about 1 to 3 mm, the thickness of the thin flexible base 9 ′ may be about 1 to 3 mm, and the thickness of the thick protrusion 9 ″ may be about 5 to 10 mm.

頭部片８には、頭部孔８’を穿設するのが好ましい。頭部孔８’に、紐体７を挿通しておくことにより、スペーサー４の散逸を防止できる。   The head piece 8 is preferably provided with a head hole 8 '. By inserting the cord body 7 into the head hole 8 ', the spacer 4 can be prevented from dissipating.

スペーサー本体部４’には、頭部孔８’の他に、仕切部孔９’’’及び連結部孔１０”を穿設するのが好ましい。仕切部孔９’’’を穿設することにより、仕切部片９の柔軟性が向上し、ガラス板３主面に接触した際、ガラス板３主面の曲面に沿ってより曲がりやすくなる。連結部孔１０”を穿設することにより、連結薄片１０の柔軟性が向上してスペーサー４をガラス板３周縁部へ装着しやすくなると共に、仕切部片９がガラス板３主面に強く密着するのを防ぐ。また、スペーサー本体部４’の材料であるプラスチックの使用量を減らせるので、スペーサー本体部４の製造費用を抑えることができる。
２．布体について
布体１１は仕切部片９とガラス板３の主面の間に介在させる。こうすることにより仕切部片９の接触跡が生じにくくなる。また、仕切部片９とガラス板３主面との間の緩衝性も向上する。
布体１１の材質には、特に限定されるものではないが、ポリエチレン樹脂、ポリプロピレン樹脂、ポリエステル樹脂、ポリアミド樹脂、ポリウレタン樹脂、又は、木綿のような天然繊維のものが入手しやすく好ましい。また、布体１１の組織には、特に限定されるものではないが、織物、編み物（メリヤス生地）、レース、フェルト、不織布などを挙げることができる。 In addition to the head hole 8 ', it is preferable to form a partition hole 9'"and a connecting portion hole 10" in the spacer body 4 '. The partition hole 9'"is formed. Thereby, the flexibility of the partition piece 9 is improved, and when the partition piece 9 comes into contact with the main surface of the glass plate 3, it becomes easier to bend along the curved surface of the main surface of the glass plate 3. The flexibility of the connecting thin piece 10 is improved, so that the spacer 4 can be easily attached to the peripheral edge of the glass plate 3, and at the same time, the partition piece 9 is prevented from strongly adhering to the main surface of the glass plate 3. Further, since the amount of plastic used as the material of the spacer body 4 'can be reduced, the manufacturing cost of the spacer body 4 can be reduced.
2. The cloth body 11 is interposed between the partition piece 9 and the main surface of the glass plate 3. By doing so, contact marks of the partition piece 9 are less likely to occur. Further, the cushioning property between the partition piece 9 and the main surface of the glass plate 3 is also improved.
The material of the cloth body 11 is not particularly limited, but is preferably a polyethylene fiber, a polypropylene resin, a polyester resin, a polyamide resin, a polyurethane resin, or a natural fiber such as cotton, which is easily available. Further, the structure of the cloth body 11 is not particularly limited, and examples thereof include woven fabric, knitted fabric (knitted fabric), lace, felt, and nonwoven fabric.

例えば、仕切部片９の両面が布体１１により完全に覆われ、仕切部片９が直にガラス板３主面に接触することなく、必ず布体１１を介して接触する態様となるように、布体１１の大きさ及び形状を決めればよい。例えば、図１に示すように、薄いネット状の１つの袋状の布体１１でスペーサー本体部４’の大部分を覆う態様になる布体１１の大きさ及び形状としてもよい。すなわち、横幅が連結薄片１０の横幅を収容するに足る長さで、縦幅が連結薄片１０と仕切部片９の縦方向長さの２倍よりやや大きく連結薄片１０と仕切部片９の全面を覆うに足る長さの袋状の布体１１とすればよい。このような袋状の布体１１としては、好ましくは、ポリエステル樹脂製の薄く柔らかいネット状の袋が挙げられる。又は、スペーサー本体部４’の一対の仕切部片９の個々を仕切部片９の部分だけを覆う態様になる２つの袋状の布体１１を用いてもよい。   For example, both sides of the partition piece 9 are completely covered with the cloth body 11 so that the partition piece 9 does not directly contact the main surface of the glass plate 3 but always comes into contact with the glass body 3 via the cloth body 11. The size and shape of the cloth body 11 may be determined. For example, as shown in FIG. 1, the size and shape of the cloth body 11 may be such that one thin net-like bag-shaped cloth body 11 covers most of the spacer body 4 ′. That is, the horizontal width is long enough to accommodate the horizontal width of the connecting thin piece 10, and the vertical width is slightly larger than twice the vertical length of the connecting thin piece 10 and the partitioning piece 9, and the entire surface of the connecting thin piece 10 and the partitioning piece 9. May be a bag-like cloth body 11 having a length sufficient to cover the cloth. As such a bag-like cloth 11, preferably, a thin soft net-like bag made of polyester resin is used. Alternatively, two bag-shaped cloth bodies 11 may be used in which each of the pair of partition pieces 9 of the spacer body 4 ′ covers only the partition piece 9.

袋状の布体１１の開口部周縁は、ゴム等の弾性を有する紐状物１２を備え、袋状の布体１１の開口部周縁がスペーサー本体部４’の連結薄片１０に密接するのが好ましい。このようにすることにより、スペーサー本体部４’と袋状の布体１１が一体化しスペーサー４の取り扱いが容易になる。さらに、スペーサー４をガラス板３の周縁部に挟み込む際に、袋状の布体１１が仕切部片９からズレて仕切部片９が直にガラス板表面に接触する虞がなくなる。   The periphery of the opening of the bag-shaped cloth body 11 is provided with a cord-like material 12 having elasticity such as rubber, and the periphery of the opening of the bag-shaped cloth body 11 is in close contact with the connecting thin piece 10 of the spacer body 4 '. preferable. By doing so, the spacer body 4 'and the bag-shaped cloth 11 are integrated, and the handling of the spacer 4 is facilitated. Further, when the spacer 4 is sandwiched between the peripheral edges of the glass plate 3, there is no possibility that the bag-shaped cloth 11 shifts from the partition piece 9 and the partition piece 9 comes into direct contact with the glass plate surface.

他に、仕切部片９が、布体１１を介して接触する態様にするためには、仕切部片９の大きさに相当する大きさの布体１１を、接着剤を用いて直接仕切部片９に貼り付ける方法もあるが、布体１１が汚れたり破れたりしたときの交換のし易さから袋状の布体１１の方が、より好ましい。   In addition, in order for the partition pieces 9 to be in contact with each other via the cloth body 11, the cloth body 11 having a size corresponding to the size of the partition pieces 9 is directly separated from the partition piece 9 using an adhesive. Although there is a method of sticking to the piece 9, the bag-shaped cloth 11 is more preferable because the cloth 11 can be easily replaced when it becomes dirty or torn.

又は、前記のようにスペーサー本体部４’と布体１１を一体とした態様としないで、袋状でない適度な大きさの布体１１を予めガラス板３周縁部に配置し、布体１１の上からガラス板３周縁部にスペーサー本体部４’を挟み込み、仕切部片９が直にガラス板表面と接触しないようにする方法もある。しかし、スペーサー本体部４’と布体１１が一体となっていないので、スペーサー本体部４’を装着しながらガラス板３をパレット１に積載する際の作業が煩雑となることから、前記の袋状の布体１１を予めスペーサーの本体部４’の仕切部片９に装着して一体とした態様にしておくのが好ましい。   Alternatively, instead of forming the spacer body 4 ′ and the cloth body 11 in an integrated manner as described above, a cloth body 11 of an appropriate size that is not a bag shape is arranged in advance on the periphery of the glass plate 3, and There is also a method in which the spacer body 4 'is sandwiched between the periphery of the glass plate 3 from above so that the partition piece 9 does not directly contact the surface of the glass plate. However, since the spacer body 4 'and the cloth body 11 are not integrated, the work of loading the glass plate 3 on the pallet 1 while attaching the spacer body 4' becomes complicated. It is preferable that the cloth body 11 is attached to the partition piece 9 of the main body 4 ′ of the spacer in advance to form an integral form.

袋状の布体１１としては、例えば、家庭台所用品として排水口や三角コーナーのごみ捕捉ネットに用いられる「水切りネット（布体はポリエステル樹脂製の糸の編み物で、袋状に加工してある）」（株式会社大創産業）を挙げることができる。   As the bag-like cloth 11, for example, a drainer net (a cloth is a knitted polyester resin thread and is processed into a bag-like shape, which is used as a household kitchen appliance for a drainage port or a dust trapping net at a triangular corner). ) "(Daisou Sangyo Co., Ltd.).

図４に示すように、ガラス板用パレット１にガラス板３を縦積みする際に前記スペーサー４を用いた。ガラス板３をパレットに積載する態様は、ガラス板３の破損しにくさから縦積が横積みより好ましい。ガラス板３を縦積するときは、スペーサー４は、ガラス板３に1枚おきに装着される。ガラス板３を縦積すると、ガラス板３同志が寄るので、スペーサーの仕切部片９は押されガラス板主面に密着する。このとき、スペーサー４の仕切部片９は、スペーサー４を装着したガラス板主面と隣のガラス板主面双方に密着する。しかし、連結薄片１０とガラス板３主面とは接しない。開放していた仕切部片９をガラス板３主面に密着したとき連結薄片１０が変形し歪を吸収する。 A specific example of the spacer of the present invention and a method of using the spacer will be described with reference to FIGS.
<Example>
1. Preparation of spacer 4 (spacer body 4 ')
A clip-type spacer main body 4 ′ having the shape shown in FIG. 2 was prepared. The spacer body 4 ′ includes a head piece 8 that contacts the end face of the glass plate 3, a pair of partition pieces 9 that contact the main face of the glass plate 3 at a predetermined distance from the end face of the glass plate 3, A piece 8 and a partition piece 9 were connected, and consisted of a pair of connecting thin pieces 10 (thickness 3 mm) which did not contact the main surface of the glass plate 3. Further, the partition piece 9 is constituted by arranging a large number of thick protrusions 9 "abutting on the main surface of the glass plate 3 on a thin flexible base 9 '. The thickness was 2-3 mm, and the thick protrusion 9 ″ was 9 mm. The distance between the pair of connecting thin pieces 10 was selected to be 10 mm. The spacer body 4 'was made of polyethylene resin and was manufactured by molding means such as injection molding.
(Cloth 11 and spacer 4)
The cloth body 11 has a horizontal width of 110 mm, a vertical width of 120 mm, and a thickness of 0.06 mm “a drainage net (the cloth body is a knitted yarn of polyester resin having a diameter of 0.045 mm and processed into a bag shape)” (stock) Company Daiso Sangyo) was prepared. The bag-shaped cloth body 11 was mounted on the spacer body 4 'to obtain the spacer 4 in which the pair of partitioning pieces 9 were completely covered with the cloth body 11 as shown in FIG.
2. Attachment of spacers 4 when vertically stacking glass plates 3 on pallet 1 for glass plates As shown in FIG. 4, the spacers 4 were used when vertically stacking glass plates 3 on the pallet 1 for glass plates. In the mode of loading the glass plates 3 on a pallet, the vertical stacking is more preferable than the horizontal stacking because the glass plates 3 are not easily damaged. When vertically stacking the glass plates 3, the spacers 4 are attached to every other glass plate 3. When the glass plates 3 are stacked vertically, the glass plates 3 come closer to each other, so that the partition piece 9 of the spacer is pressed and comes into close contact with the main surface of the glass plate. At this time, the partition piece 9 of the spacer 4 is in close contact with both the glass plate main surface on which the spacer 4 is mounted and the adjacent glass plate main surface. However, the connecting flake 10 does not contact the main surface of the glass plate 3. When the opened partition piece 9 is brought into close contact with the main surface of the glass plate 3, the connecting thin piece 10 is deformed and absorbs distortion.

図５に示すように、ガラス板用パレット１は、該ガラス板用パレット１の内底部に配設したガラス板下縁支持具２を有した。該ガラス板下縁支持具２は、上面に刻成した溝を有した。該溝にガラス板３の下端を遊嵌させ、ガラス板３は隔置された。
スペーサー４は、各ガラス板３に1枚おきにその上側周縁部を厚さ方向に挟み込まれ、各ガラス板３を離隔保持した。
図４、図５に示すように、押圧杆５は、ガラス板３の上端部およびスペーサー４を押圧し、さらにその先端からパレット底部先端にかけてバンド６を緊締することにより、搬送時のガラス板３の揺動を抑制した。なお、紐体７で、後述する各スペーサー４の頭部片に穿設した孔８’に挿通しておくことにより、開梱時のスペーサー４の散逸を防止できた。
３．スペーサー４の装着時及び装着後のガラス板３主面の状態
スペーサー４を厚さ５ｍｍのガラス板３に装着し、ガラス板用パレット１にガラス板３を３６枚縦積みして、スペーサー４とガラス板３主面との接触状態の観察を行った。
布体１１は、ポリエステル樹脂製の編み物で、袋状に加工してあり、1つの袋で、スペーサー本体部４’の仕切部片９全体を覆うことができた。仕切部片９は、薄手の可撓性基部９’に厚手の突出部９”を適宜複数配設したので、湾曲したガラス板３の主面と布体１１を介して良好に密接していた。
常温で３日間放置後、前記縦積したガラス板３を解いて、全てのガラス板３の主面を目視観察したところ、スペーサー４の接触跡は確認できなかった。
＜比較例＞
前記実施例のスペーサー４の代わりに、スペーサー本体部４’を用いて観察を実施した。すなわち、前記実施例と同じようにスペーサー本体部４’をガラス板３に装着してガラス板用パレット１に３６枚縦積みして、スペーサー本体部４’とガラス板３主面との接触状態の観察を行った。
仕切部片９は、薄手の可撓性基部９’に厚手の突出部９”を適宜複数配設したので、湾曲したガラス板３の主面と直に密接していた。
常温で３日間放置後、前記縦積したガラス板３を解いて、全てのガラス板３の主面を目視観察したところ、３６枚全てのガラス板３主面にスペーサー本体部４’の接触跡を確認した。
以上のように、本発明のスペーサー４を用いて縦積みしたガラス板３の主面は、スペーサー４の接触跡を目視で確認できないレベルの外観品質を有することが分かった。 As shown in FIG. 5, the glass plate pallet 1 had a glass plate lower edge support 2 disposed on the inner bottom of the glass plate pallet 1. The glass plate lower edge support 2 had a groove formed in the upper surface. The lower end of the glass plate 3 was loosely fitted in the groove, and the glass plate 3 was separated.
The spacers 4 have the upper peripheral portion sandwiched in the thickness direction for every other glass plate 3 to hold the glass plates 3 apart.
As shown in FIGS. 4 and 5, the pressing rod 5 presses the upper end of the glass plate 3 and the spacer 4, and further tightens the band 6 from the tip to the tip of the pallet bottom. Swaying was suppressed. In addition, the string body 7 was inserted into a hole 8 ′ formed in a head piece of each spacer 4, which will be described later, to prevent the spacer 4 from being dissipated when unpacked.
3. State of the main surface of the glass plate 3 at the time of mounting and after mounting the spacer 4 The spacer 4 is mounted on the glass plate 3 having a thickness of 5 mm, and 36 glass plates 3 are vertically stacked on the pallet 1 for glass plates. The state of contact with the main surface of the glass plate 3 was observed.
The cloth body 11 was made of a knitted fabric made of polyester resin and processed into a bag shape, and one bag could cover the entire partition piece 9 of the spacer body 4 '. Since the partition piece 9 is provided with a plurality of thick protrusions 9 ″ as appropriate on the thin flexible base 9 ′, the partition piece 9 is in good contact with the main surface of the curved glass plate 3 via the cloth 11. .
After standing at room temperature for 3 days, the vertically stacked glass plates 3 were unwound and the main surfaces of all the glass plates 3 were visually observed. As a result, no contact trace of the spacer 4 could be confirmed.
