Description

本発明は、複数枚のガラス基板を所定間隔を空けて並列配置して梱包するための梱包技術の改良に関する。   The present invention relates to an improvement in packaging technology for packaging a plurality of glass substrates in parallel with a predetermined interval.

周知のように、液晶ディスプレイ、プラズマディスプレイ、エレクトロルミネッセンスディスプレイ、フィールドエミッションディスプレイなどのフラットパネルディスプレイ(以下、単にFPDという)用のガラス基板を初めとする各種ガラス基板を梱包する手法としては、複数枚のガラス基板を所定間隔を空けて平行に配列して梱包する手法が採用される場合がある。   As is well known, as a method of packing various glass substrates including glass substrates for flat panel displays (hereinafter simply referred to as FPD) such as liquid crystal displays, plasma displays, electroluminescence displays, field emission displays, etc., there are a plurality of methods. In some cases, the glass substrates are packed in parallel with a predetermined interval.

この種の梱包手法としては、例えば下記の特許文献1には、複数枚のガラス板を所定間隔を空けて並列配置し、この並列配置されたガラス基板のそれぞれの四角部に保持パッド(緩衝材)を配設して、この保持パッドによって各ガラス板の相互間の間隔を維持した状態で梱包する手法が開示されている。具体的には、この保持パッドは、発泡樹脂を断面略L字形に一体成形したものであって、その内側にはL字に沿ってガラス基板の角部を形成する隣接二辺を保持する保持溝(基板挿入溝)が複数本設けられている。そして、かかる保持パッドのL字を構成する片側又は両側の部材の端部(角部側)には、保持溝の形成領域に対して凹状となる保持溝の非形成領域が設けられている。すなわち、保持溝の非形成領域が、保持溝の形成領域に対して薄肉となっている。   As a packaging method of this type, for example, in Patent Document 1 below, a plurality of glass plates are arranged in parallel at a predetermined interval, and a holding pad (buffer material) is provided on each square portion of the glass substrates arranged in parallel. ) And packaging in a state where the distance between the glass plates is maintained by the holding pad. Specifically, this holding pad is formed by integrally molding a foamed resin with a substantially L-shaped cross section, and holds two adjacent sides that form the corners of the glass substrate along the L shape inside the holding pad. A plurality of grooves (substrate insertion grooves) are provided. And the holding groove non-formation area | region which becomes concave with respect to the formation area of a holding groove is provided in the edge part (corner part side) of the member of the one side or both sides which comprises the L shape of this holding pad. That is, the region where the holding groove is not formed is thinner than the region where the holding groove is formed.

また、下記の特許文献2には、前述のように、発泡樹脂で一体成形された断面略L字形の保持パッドの外側に、そのL字に沿うように、L字形を呈するステンレス製の補強部材(第1補強部材)を固定することが開示されている。

Further, as described above, in Patent Document 2 below, a stainless steel reinforcing member having an L shape is formed on the outside of a substantially L-shaped holding pad integrally formed with foamed resin so as to follow the L shape. It is disclosed that the (first reinforcing member) is fixed.
Japanese Patent Laid-Open No. 10-230975 JP 2003-63582 A

ところで、近年、液晶ディスプレイ用のガラス基板や、プラズマディスプレイ用のガラス基板に代表されるように、各種ガラス基板には大型化が推進されているのが実情であり、その大きさも様々なものが製作されるに至っている。そのため、かかる大型のガラス基板であっても、その複数枚を所定間隔を空けて並列配置した状態で確実に梱包することが要請されている。   By the way, in recent years, as represented by glass substrates for liquid crystal displays and glass substrates for plasma displays, it is a fact that various glass substrates are being increased in size, and there are various sizes. It has been produced. Therefore, even such a large glass substrate is required to be reliably packed in a state in which a plurality of such glass substrates are arranged in parallel at a predetermined interval.

しかしながら、上記の特許文献1,2に開示の発泡樹脂で一体成形された保持パッドによって、大型のガラス基板を梱包する場合には、そのガラス基板の角部近傍のみを保持するだけでは、ガラス基板が撓みを来たすなどして隣接するガラス基板同士が接触し、梱包状態が極めて不安定となる。したがって、ガラス基板の大きさに応じて保持パッドも大型なものとし、ガラス基板の角部からその辺に沿ってある程度離れた位置までを保持する必要が生じ得る。ところが、この場合には、ガラス基板と保持パッドとの接触面積が必要以上に増大し、保持パッドから不当に多くの粉塵が発生し、ガラス基板が汚染されるおそれがある。したがって、大型のガラス基板を保持する際には、ガラス基板の角部からある程度離れた位置を、小さい接触面積で保持することが必要となる。   However, when packing a large glass substrate with the holding pad integrally formed with the foamed resin disclosed in Patent Documents 1 and 2 above, the glass substrate only needs to be held near the corners of the glass substrate. However, the adjacent glass substrates come into contact with each other due to bending, and the packaging state becomes extremely unstable. Therefore, it may be necessary to make the holding pad large in accordance with the size of the glass substrate and hold it from the corner of the glass substrate to a position some distance along the side. However, in this case, the contact area between the glass substrate and the holding pad increases more than necessary, and an excessive amount of dust is generated from the holding pad, which may contaminate the glass substrate. Therefore, when holding a large glass substrate, it is necessary to hold a position away from the corner of the glass substrate to some extent with a small contact area.

すなわち、同文献に開示の保持パッドにおいて、ガラス基板との接触面積を不当に拡大することなく、保持溝の形成領域をガラス基板の角部からある程度離して位置させるために、保持溝の非形成領域をガラス基板の辺に沿う方向に拡張する必要がある。   That is, in the holding pad disclosed in the same document, the holding groove is not formed in order to position the holding groove forming region away from the corner of the glass substrate to some extent without unduly increasing the contact area with the glass substrate. It is necessary to extend the region in a direction along the side of the glass substrate.

しかしながら、上記の特許文献1,2に開示の保持パッドは、ガラス基板の角部周辺における一辺と、この一辺と直交する他辺とをそれぞれ支持する2つの保持溝が単一の発泡樹脂成形体に設けられていることから、梱包対象となるガラス基板の大きさが変更された場合には、発泡樹脂成形体の大きさも変更する必要が生じ得る。しかも、発泡樹脂成形体の製作には、その大きさ毎に専用の金型が必要となると共に、各金型の構成も発泡樹脂成形体の形状に合わせて複雑に成らざるを得ない。したがって、発泡樹脂成形体の大きさ毎に別途専用の金型を製作することは、金型の製作費や設備維持費等の面からも実用上困難となる。特に少量多品種のガラス基板を梱包することが要請された場合には、かかる要請に対応することは実質的に不可能となる。よって、種々の大きさのガラス基板を梱包することが要請される場合には、実用的な対策とは成り得ない。   However, the holding pads disclosed in the above Patent Documents 1 and 2 have a single foamed resin molded product in which two holding grooves for supporting one side around the corner of the glass substrate and the other side perpendicular to the one side are single. Therefore, when the size of the glass substrate to be packed is changed, the size of the foamed resin molded body may need to be changed. In addition, the manufacture of the foamed resin molded body requires a dedicated mold for each size, and the configuration of each mold must be complicated according to the shape of the foamed resin molded body. Therefore, it is practically difficult to manufacture a dedicated mold separately for each size of the foamed resin molded body from the viewpoint of mold manufacturing costs, equipment maintenance costs, and the like. In particular, when it is requested to pack a small amount of various types of glass substrates, it is substantially impossible to meet such a request. Therefore, when it is required to package glass substrates of various sizes, it cannot be a practical measure.

本発明は、上記実情に鑑み、複数枚のガラス基板を所定の間隔を空けて並行に配列して梱包する梱包形態を採用する場合に、梱包対象となるガラス基板の大きさが変更されたときであっても、各大きさのガラス基板を不当に支持面積を拡大することなく確実に保持し得る梱包材を、低コストで提供することを技術的課題とする。   In view of the above situation, the present invention adopts a packaging form in which a plurality of glass substrates are arranged in parallel at predetermined intervals and packed, and when the size of the glass substrate to be packed is changed Even so, it is a technical problem to provide, at a low cost, a packaging material that can reliably hold glass substrates of various sizes without unduly increasing the support area.

上記課題を解決するために創案された本発明に係る梱包材は、所定間隔を空けて並列配置される複数枚のガラス基板のそれぞれの角部周辺における一辺を保持する保持溝を複数本有する緩衝部材からなる第1保持パッドと、前記複数枚のガラス基板のそれぞれの角部周辺における一辺と直交する他辺を保持する保持溝を複数本有する緩衝部材からなる第2保持パッドとを備えてなる梱包材であって、前記第1保持パッドと、前記第2保持パッドとを、それぞれ前記各ガラス基板の角部から離間させて配置した状態で、連結部材にそれぞれ固定したことに特徴づけられる。   The packing material according to the present invention, which was created to solve the above-mentioned problems, is a buffer having a plurality of holding grooves for holding one side around each corner of a plurality of glass substrates arranged in parallel at a predetermined interval. A first holding pad made of a member, and a second holding pad made of a buffer member having a plurality of holding grooves for holding the other side orthogonal to one side around each corner of the plurality of glass substrates. A packaging material, characterized in that the first holding pad and the second holding pad are respectively fixed to a connecting member in a state of being spaced apart from corners of the glass substrates.

このような構成によれば、ガラス基板の角部周辺における一辺と、この一辺と直交する他辺とをそれぞれ保持する保持パッドが、それぞれ別体に構成され、これら別体に構成された第1保持パッドおよび第2保持パッドが連結部材にそれぞれ固定されていることから、梱包対象となるガラス基板の大きさが変更された場合であっても、連結部材のガラス基板の辺に沿う方向の寸法を変更するか、或いは連結部材に対する第1保持パッド又は第2保持パッドの固定位置を変更するだけで、ガラス基板との接触面積を不当に拡張することなく、そのガラス基板の大きさに応じた最適な位置でガラス基板を確実に保持することが可能となる。この際、保持パッド自体は変更する必要がないので、ガラス基板の大きさが変更された場合であっても、保持パッドとして共通の緩衝部材を利用することが可能となる。すなわち、例えば保持パッドを発泡樹脂等の緩衝部材によって成形した場合であっても、ガラス基板の大きさに応じて金型を別途製作する必要がなくなる。しかも、保持パッドは、ガラス基板の辺を保持する保持溝が形成されている以外は特に複雑な構造とする必要もないので、その製作が容易となる。したがって、仮に緩衝部材を発泡樹脂で一体成形した場合であっても、梱包材全体を発泡樹脂等の緩衝部材によって一体成形した場合に比して、その製造工程が簡素化され、製造コストの大幅な削減を図ることが可能となる。   According to such a configuration, the holding pads that respectively hold one side around the corner of the glass substrate and the other side orthogonal to the one side are configured separately, and the first configured in these separate units. Since the holding pad and the second holding pad are respectively fixed to the connecting member, even if the size of the glass substrate to be packed is changed, the dimension of the connecting member in the direction along the side of the glass substrate Or by changing the fixing position of the first holding pad or the second holding pad with respect to the connecting member, according to the size of the glass substrate without unduly expanding the contact area with the glass substrate. It is possible to securely hold the glass substrate at the optimum position. At this time, since it is not necessary to change the holding pad itself, a common buffer member can be used as the holding pad even when the size of the glass substrate is changed. That is, for example, even when the holding pad is formed by a cushioning member such as foamed resin, it is not necessary to separately manufacture a mold according to the size of the glass substrate. In addition, since the holding pad does not need to have a particularly complicated structure except that a holding groove for holding the side of the glass substrate is formed, its manufacture becomes easy. Therefore, even if the cushioning member is integrally molded with foamed resin, the manufacturing process is simplified and the manufacturing cost is greatly increased compared to the case where the entire packing material is integrally molded with foamed resin or other cushioning member. Reduction can be achieved.

上記の構成において、前記連結部材は、前記第1保持パッドおよび前記第2保持パッドよりも剛性が高いことが好ましい。   Said structure WHEREIN: It is preferable that the said connection member has rigidity higher than a said 1st holding pad and a said 2nd holding pad.

このようにすれば、梱包対象となるガラス基板の大きさに応じて連結部材の寸法を大きくした場合であっても、梱包材全体の剛性が不当に低下することがない。したがって、ガラス基板の角部からある程度離して第1保持パッド又は第2保持パッドを位置させたとしても、ガラス基板に対して第1保持パッドや第2保持パッドが変位を来たすという事態も好適に防止することが可能となる。なお、連結部材を、例えば金属製等にすることで、低コストで連結部材に適度な剛性を付与することが可能となる。   In this way, even when the dimension of the connecting member is increased according to the size of the glass substrate to be packed, the rigidity of the entire packing material is not unduly lowered. Therefore, even when the first holding pad or the second holding pad is positioned to some extent away from the corner of the glass substrate, it is preferable that the first holding pad or the second holding pad is displaced with respect to the glass substrate. It becomes possible to prevent. In addition, it becomes possible to give moderate rigidity to a connection member at low cost by making a connection member into a metal etc., for example.

上記の構成において、前記第1保持パッドおよび前記第2保持パッドは、前記連結部材にそれぞれ着脱可能に固定されていることが好ましい。   Said structure WHEREIN: It is preferable that the said 1st holding pad and the said 2nd holding pad are each fixed to the said connection member so that attachment or detachment is possible.

すなわち、梱包に際して連結部材は通常は劣化しないが、保持パッドはガラス基板と実際に接触するため劣化するおそれがある。そこで、上記のようにすれば、保持パッドが劣化した場合であっても、かかる保持パッドを取り替えるだけで、連結部材はそのまま使用することが可能となり、コスト面からも有利となる。   That is, the connecting member does not normally deteriorate during packaging, but the holding pad may actually deteriorate because it contacts the glass substrate. Therefore, with the above configuration, even when the holding pad is deteriorated, the connecting member can be used as it is simply by replacing the holding pad, which is advantageous from the viewpoint of cost.

この場合、前記連結部材に対する前記別体に構成された第1保持パッドおよび第2保持パッドの固定位置を、ガラス基板の角部を形成する辺に沿う方向にそれぞれ調整可能に構成してもよい。このようにすれば、ガラス基板の大きさに応じて、各保持パッドによるガラス基板の保持位置を適宜調整することができるので、種々の大きさのガラス基板を容易且つ確実に保持することが可能となる。   In this case, the fixing positions of the first holding pad and the second holding pad configured separately from the connecting member may be configured to be adjustable in directions along the sides forming the corners of the glass substrate. . In this way, since the holding position of the glass substrate by each holding pad can be adjusted as appropriate according to the size of the glass substrate, it is possible to easily and reliably hold glass substrates of various sizes. It becomes.

上記の構成において、前記連結部材は、その外側から内側が視認可能に構成されていることが好ましい。   Said structure WHEREIN: It is preferable that the said connection member is comprised so that the inner side can be visually recognized from the outer side.

このようにすれば、ガラス基板の角部を形成する隣接二辺に梱包材を配設する際に、連結部材の外側からその内側に位置するガラス基板の位置を確認できるので、ガラス基板に対する梱包材の位置決めを容易に実行することが可能となる。また、ガラス基板に梱包材を配設した後であっては、連結部材の外側からその内側に梱包されたガラス基板の状態を確認できるので、ガラス基板に破損等の不具合が生じた場合であっても、早期に不具合を発見し、かかる不具合が他のガラス基板に波及するのを未然に防ぐことが可能となる。   In this way, when the packaging material is disposed on the two adjacent sides that form the corners of the glass substrate, the position of the glass substrate positioned on the inner side can be confirmed from the outer side of the connecting member. The positioning of the material can be easily performed. In addition, after the packaging material is disposed on the glass substrate, the state of the glass substrate packed inside the connecting member can be confirmed from the outside of the connecting member. However, it is possible to detect a problem at an early stage and prevent the problem from spreading to other glass substrates.

この場合、前記第1保持パッドおよび前記第2保持パッドを複数の前記連結部材で固定すると共に、各連結部材の相互間に隙間を形成することが好ましい。   In this case, it is preferable that the first holding pad and the second holding pad are fixed by the plurality of connecting members, and a gap is formed between the connecting members.

このようにすれば、例えば連結部材を金属製とした場合であっても、連結部材の外側からその内側を視認することが可能となる。また、隙間を形成することなく連結部材を単一の板状体で形成した場合に比して、梱包材の軽量化を図ることができるので、ガラス基板への梱包材の配設作業(取り付け作業)及び取り外し作業を円滑且つ容易に実行することが可能となる。   If it does in this way, even if it is a case where a connection member is metal, for example, it will become possible to visually recognize the inside from the outside of a connection member. In addition, the packaging material can be reduced in weight compared to the case where the connecting member is formed of a single plate-like body without forming a gap. Work) and removal work can be carried out smoothly and easily.

上記課題を解決するために創案された本発明に係るガラス基板梱包体は、所定間隔を空けて並列配置される複数枚のガラス基板の角部に、上記の構成を適宜備えた梱包材を配設して梱包したことに特徴づけられる。   The glass substrate package according to the present invention, which has been created to solve the above-described problems, is provided with a packing material appropriately having the above-described configuration at the corners of a plurality of glass substrates arranged in parallel at a predetermined interval. Characterized by installation and packaging.

このような構成によれば、既に述べた梱包材が有する作用効果を同様に享受することができる。   According to such a structure, the effect which the packing material already described can have can be enjoyed similarly.

以上のように本発明によれば、保持パッドが、ガラス基板の角部周辺における一辺と、この一辺と当該角部で直交する他辺とで、それぞれ別体に構成され、且つこれら別体に構成された第1保持パッドおよび第2保持パッドが連結部材にそれぞれ固定されていることから、梱包対象となるガラス基板の大きさが変更された場合であっても、連結部材のガラス基板の辺に沿う方向の寸法を変更するか、或いは連結部材に対する第1保持パッド又は第2保持パッドの固定位置を変更するだけで、当該ガラス基板を安定した状態で保持して梱包することが可能となる。また、梱包対象となるガラス基板の大きさが変更されたとしても、各大きさのガラス基板につき、保持パッドとして共通の緩衝部材を使用することができるので、共通の緩衝部材を使用することが実質的に不可能となる発泡樹脂等によってL字形に一体成形された保持パッドに比して、製造コストの大幅な削減を図ることが可能となる。   As described above, according to the present invention, the holding pad is configured separately in one side around the corner of the glass substrate and the other side orthogonal to the one side and the corner. Since the configured first holding pad and second holding pad are respectively fixed to the connecting member, the side of the glass substrate of the connecting member can be obtained even when the size of the glass substrate to be packed is changed. It is possible to hold and package the glass substrate in a stable state simply by changing the dimension in the direction along the direction or by changing the fixing position of the first holding pad or the second holding pad with respect to the connecting member. . Moreover, even if the size of the glass substrate to be packed is changed, a common buffer member can be used as a holding pad for each size glass substrate, so that a common buffer member can be used. Compared to a holding pad integrally formed in an L shape with a foamed resin or the like that is substantially impossible, the manufacturing cost can be greatly reduced.

以下、本発明の実施形態を添付図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図1は、本発明の一実施形態に係る梱包材を模式的に示す斜視図である。図4は、この梱包材を用いたガラス基板梱包体を模式的に示す斜視図である。図1および図4に示すように、この梱包材1は、所定間隔を空けて並列配置される複数枚のガラス基板Gのそれぞれの角部における一辺を保持する保持溝2を複数本有する緩衝部材からなる第1保持パッド3aと、前記複数枚のガラス基板Gのそれぞれの角部における一辺と当該角部で直交する他辺を保持する保持溝2を複数本有する緩衝部材からなる第2保持パッド3bとを備えている。   FIG. 1 is a perspective view schematically showing a packaging material according to an embodiment of the present invention. FIG. 4 is a perspective view schematically showing a glass substrate package using this packing material. As shown in FIGS. 1 and 4, the packing material 1 includes a buffer member having a plurality of holding grooves 2 that hold one side at each corner of a plurality of glass substrates G that are arranged in parallel at predetermined intervals. 1st holding pad 3a which consists of this, and the 2nd holding pad which consists of a buffer member which has two or more holding grooves 2 holding the other side which intersects perpendicularly in the corner by one side in each corner of a plurality of glass substrates G 3b.

詳述すると、図1および図4に示すように、上記の第1保持パッド3aおよび第2保持パッド3bは、それぞれ各ガラス基板Gの角部から離間して配置された状態で、これら保持パッド3a,3bよりも剛性の高い断面略L字形の連結部材4にそれぞれ固定されている。本実施形態では、この連結部材4は、ステンレス等の金属によって形成されており、保持パッド3a,3bの保持溝2の配列方向に間隔を空けた複数(図示例では2つ)の部材から構成されている。そして、これら別体に形成された連結部材4の角部には、必要に応じて断面L字形の補強部材5が固定されるようになっている。   More specifically, as shown in FIGS. 1 and 4, the first holding pad 3 a and the second holding pad 3 b are arranged so as to be spaced apart from the corners of the glass substrates G, respectively. It is fixed to a connecting member 4 having a substantially L-shaped cross section having higher rigidity than 3a and 3b. In the present embodiment, the connecting member 4 is made of a metal such as stainless steel, and includes a plurality of (two in the illustrated example) members spaced in the arrangement direction of the holding grooves 2 of the holding pads 3a and 3b. Has been. And the reinforcement member 5 of L-shaped cross section is fixed to the corner | angular part of the connection member 4 formed in these separately as needed.

図2に示すように、第1保持パッド3a(第2保持パッド3b)の保持溝2には、ガラス基板Gが容易に嵌合するように、その開口部側にテーパー面2aが形成されている。また、第1保持パッド3a(第2保持パッド3b)のうち、保持溝2の底部に対応する肉厚Aは、2〜15mm、より好ましくは6〜12mmに設定される。すなわち、保持溝2の底部に対応する肉厚Aが、2mmよりも小さくなると、ガラス基板Gへの衝撃を吸収することができず、また繰り返し使用することによる荷重変形により所望の性能が得られなくなる。一方、15mmを超えると、ガラス基板Gの破損防止効果に差がなくなり、不当に肉厚だけが増加することになり省スペース化の観点からも不適当となる。したがって、保持溝2の底部に対応する肉厚Aを、上記の数値範囲に設定することでこれらの問題を好適に解消することが可能となる。   As shown in FIG. 2, the holding groove 2 of the first holding pad 3a (second holding pad 3b) is formed with a tapered surface 2a on the opening side so that the glass substrate G can be easily fitted. Yes. Moreover, the thickness A corresponding to the bottom of the holding groove 2 in the first holding pad 3a (second holding pad 3b) is set to 2 to 15 mm, more preferably 6 to 12 mm. That is, when the thickness A corresponding to the bottom of the holding groove 2 is smaller than 2 mm, the impact on the glass substrate G cannot be absorbed, and desired performance can be obtained by load deformation due to repeated use. Disappear. On the other hand, if it exceeds 15 mm, there is no difference in the effect of preventing the glass substrate G from being damaged, and only the thickness is unreasonably increased, which is inappropriate from the viewpoint of space saving. Therefore, these problems can be preferably solved by setting the thickness A corresponding to the bottom of the holding groove 2 within the above numerical range.

また、既に述べたように、別体に形成された第1保持パッド3aおよび第2保持パッド3bは、ガラス基板Gの角部から離間して配置された状態で連結部材4にそれぞれ固定されているが、図3に示すように、連結部材4の角部からそれぞれの保持パッド3a,3bまでの離間寸法B、Cは、10mm以上、好ましくは20mm以上に設定される。すなわち、離間寸法B、Cが、10mmよりも小さいと、ガラス基板Gの梱包時に、ガラス基板Gの角部に破損が生じやすく、また梱包対象のガラス基板Gの角部近傍に位置決め用のマーキング(いわゆるアライメントマーク)が形成されているような場合にはそのマーキングに接触することなく、ガラス基板Gを保持パッド3a,3bの保持溝2に嵌合することが困難となる。したがって、連結部材4の角部からそれぞれの保持パッド3a,3bまでの離間寸法B、Cを、上記数値範囲に設定することでこれらの問題を好適に解消することが可能となる。なお、離間寸法B、Cは、それぞれ同一である必要はなく、梱包対象となるガラス基板Gの大きさに応じてそれぞれ異なる値に設定してもよい。   Further, as described above, the first holding pad 3a and the second holding pad 3b formed separately are respectively fixed to the connecting member 4 in a state of being spaced apart from the corners of the glass substrate G. However, as shown in FIG. 3, the separation dimensions B and C from the corners of the connecting member 4 to the respective holding pads 3a and 3b are set to 10 mm or more, preferably 20 mm or more. That is, when the separation dimensions B and C are smaller than 10 mm, the corners of the glass substrate G are likely to be damaged during the packaging of the glass substrate G, and positioning markings are provided near the corners of the glass substrate G to be packed. When (so-called alignment marks) are formed, it is difficult to fit the glass substrate G into the holding grooves 2 of the holding pads 3a and 3b without contacting the marking. Therefore, by setting the separation dimensions B and C from the corners of the connecting member 4 to the respective holding pads 3a and 3b within the above numerical range, these problems can be preferably solved. The separation dimensions B and C do not have to be the same, and may be set to different values according to the size of the glass substrate G to be packed.

次に、以上のような構成を備えた梱包材1を用いたガラス基板梱包体の一例を説明する。図4に示すように、ガラス基板梱包体6は、略鉛直姿勢で複数枚のガラス基板Gを相互に所定間隔を空けて並列配置し、この並列配置された複数枚のガラス基板Gのそれぞれの四角部(四つの隅角部)に梱包材1が配設されてなる。すなわち、複数枚のガラス基板Gのそれぞれの四角部において、一の角部につき、角部周辺における一辺を第1保持パッド3aの保持溝2で保持すると共に、かかる一辺と当該角部で直交する他辺を第2保持パッド3bの保持溝2で保持した状態で梱包される。   Next, an example of the glass substrate package using the packaging material 1 having the above configuration will be described. As shown in FIG. 4, the glass substrate package 6 has a plurality of glass substrates G arranged in parallel at a predetermined interval in a substantially vertical posture, and each of the plurality of glass substrates G arranged in parallel is arranged. The packing material 1 is arrange | positioned at the square part (four corner parts). That is, in each square portion of the plurality of glass substrates G, one side around the corner portion is held by the holding groove 2 of the first holding pad 3a, and the one side and the corner portion are orthogonal to each other. The other side is packed with the holding groove 2 of the second holding pad 3b.

詳述すると、梱包体6は、基台部7の上面に、ガラス基板Gの下方側に位置する2つの梱包材1が固定されており、ガラス基板Gがかかる梱包材1を介して基台部7によって下方から支持されている。他方、ガラス基板Gの上方側に位置する2つの梱包材1には、既述の補強部材5が固定されており、その補強部材5の端部が、並列配置された複数枚のガラス基板Gの周囲を囲むように、その四隅に位置する基台部7の上面に立設された4つの支柱8によって支持されている。また、この補強部材5の上には、下方が開口した箱型の上蓋9が被せられている。そして、図示しないが必要に応じて梱包体6の周囲に、ベルトやストレッチフィルム等が巻回される。なお、梱包体6の輸送環境等に応じて支柱8は取り除いてもよい。   More specifically, the packing body 6 has two packing materials 1 positioned on the lower side of the glass substrate G fixed to the upper surface of the base portion 7, and the base is placed through the packing material 1 on which the glass substrate G is applied. It is supported from below by the portion 7. On the other hand, the two reinforcing members 5 described above are fixed to the two packing materials 1 positioned above the glass substrate G, and the end portions of the reinforcing members 5 are arranged in parallel. Is supported by four support columns 8 erected on the upper surface of the base portion 7 located at the four corners. Further, a box-shaped upper lid 9 having an opening at the bottom is covered on the reinforcing member 5. And although not shown in figure, a belt, a stretch film, etc. are wound around the packing body 6 as needed. In addition, you may remove the support | pillar 8 according to the transport environment of the package 6, etc.

以上のように、本実施形態に係る梱包材1によれば、保持パッド3a,3bが、ガラス基板Gの角部を形成する隣接二辺でそれぞれ別体に構成され、これら別体に構成された第1保持パッド3aおよび第2保持パッド3bが連結部材4にそれぞれ固定されていることから、梱包対象となるガラス基板Gの大きさが変更された場合であっても、連結部材4のガラス基板Gの辺に沿う方向の寸法を変更するか、或いは連結部材4に対する保持パッド3a,3bの固定位置を変更するだけで、保持パッド3a,3bとして共通の緩衝部材を利用することが可能となる。すなわち、例えば保持パッド3a,3bを発泡樹脂等の緩衝部材によって一体成形した場合であっても、ガラス基板Gの大きさに応じて専用の金型を別途製作する必要がなくなる。しかも、保持パッド3a,3bは、ガラス基板Gの辺を保持する保持溝2が形成されている以外は特に複雑な構造とする必要もないので、その製作自体も容易となる。したがって、保持パッド3a,3bを発泡樹脂で一体成形した場合であっても、梱包材1全体を発泡樹脂等の緩衝部材によって一体成形した場合に比して、その製造工程が簡素化され、製造コストの大幅な削減を図ることが可能となる。   As described above, according to the packaging material 1 according to the present embodiment, the holding pads 3a and 3b are configured separately on the adjacent two sides forming the corners of the glass substrate G, and configured separately. Since the first holding pad 3a and the second holding pad 3b are fixed to the connecting member 4, the glass of the connecting member 4 can be used even when the size of the glass substrate G to be packed is changed. It is possible to use a common buffer member as the holding pads 3a and 3b only by changing the dimension along the side of the substrate G or by changing the fixing position of the holding pads 3a and 3b with respect to the connecting member 4. Become. That is, for example, even when the holding pads 3a and 3b are integrally formed with a cushioning member such as foamed resin, it is not necessary to separately manufacture a dedicated mold according to the size of the glass substrate G. In addition, since the holding pads 3a and 3b do not need to have a particularly complicated structure except that the holding groove 2 for holding the side of the glass substrate G is formed, the manufacturing itself is easy. Therefore, even when the holding pads 3a and 3b are integrally formed with foamed resin, the manufacturing process is simplified and manufactured as compared with the case where the entire packing material 1 is integrally formed with a cushioning member such as foamed resin. Costs can be significantly reduced.

また、連結部材4は保持パッド3a,3bよりも剛性が高いので、梱包する対象となるガラス基板Gの大きさに応じてその寸法を大きくした場合であっても、梱包材1全体の剛性が不当に低下することがない。したがって、ガラス基板Gの角部からある程度離して保持パッド3a,3bを位置させたとしても、ガラス基板Gに対して保持パッド3a,3bが変位を来たすという事態も好適に防止されるので、大型のガラス基板Gであっても保持パッド3a,3bとの接触面積を適切な範囲に維持した状態で、確実に保持することができる。   Further, since the connecting member 4 has higher rigidity than the holding pads 3a and 3b, even if the dimension is increased according to the size of the glass substrate G to be packed, the rigidity of the entire packaging material 1 is high. There is no unreasonable decline. Therefore, even if the holding pads 3a and 3b are positioned at a certain distance from the corners of the glass substrate G, the situation that the holding pads 3a and 3b are displaced with respect to the glass substrate G is preferably prevented. Even the glass substrate G can be reliably held in a state where the contact area with the holding pads 3a and 3b is maintained in an appropriate range.

さらに、連結部材4の相互間には所定の間隔が形成されているので、連結部材4の外側からその内側を視認することが可能となる。すなわち、ガラス基板Gの角部を形成する隣接二辺に梱包材1を配設する際に、連結部材4の外側からその内側に位置するガラス基板Gの位置を確認できるので、ガラス基板Gに対する梱包材1の位置決めを容易に実行することが可能となる。また、ガラス基板Gに梱包材1を配設した後であっては、連結部材4の外側からその内側に梱包されたガラス基板Gの状態を確認できるので、ガラス基板Gに破損等の不具合が生じた場合であっても、早期に不具合を発見し、かかる不具合が他のガラス基板Gに波及するのを未然に防ぐことが可能となる。   Furthermore, since a predetermined interval is formed between the connecting members 4, the inside of the connecting member 4 can be viewed from the outside. That is, since the position of the glass substrate G located on the inner side can be confirmed from the outside of the connecting member 4 when the packing material 1 is disposed on the adjacent two sides forming the corners of the glass substrate G, The positioning of the packing material 1 can be easily performed. In addition, after the packaging material 1 is disposed on the glass substrate G, the state of the glass substrate G packed on the inner side from the outside of the connecting member 4 can be confirmed. Even if it occurs, it is possible to find a problem at an early stage and prevent the problem from spreading to other glass substrates G.

なお、本発明は上記の実施形態に限定されるものではなく、種々の変形が可能である。例えば、図5に示すように、内周面に螺旋溝が形成されたネジ孔構成部材10が埋設固定されるように緩衝部材3を一体成形し、この埋設固定されたネジ孔構成部材10に連結部材4をネジ11によって固定してもよい。この場合、図6に示すように、連結部材4に保持パッド3a,3bの保持溝2に沿う方向(ガラス基板Gの辺に沿う方向)に一又は複数の長孔12を形成してもよい。このようにすれば、ガラス基板Gの大きさに応じて、保持パッド3a,3bによるガラス基板Gの保持位置を適宜調整することができるので、種々の大きさのガラス基板Gを容易且つ確実に保持することが可能となる。   In addition, this invention is not limited to said embodiment, A various deformation | transformation is possible. For example, as shown in FIG. 5, the buffer member 3 is integrally formed so that the screw hole constituent member 10 having the spiral groove formed on the inner peripheral surface is embedded and fixed, and the screw hole constituent member 10 embedded and fixed is formed. The connecting member 4 may be fixed with screws 11. In this case, as shown in FIG. 6, one or a plurality of long holes 12 may be formed in the connecting member 4 in the direction along the holding groove 2 of the holding pads 3a and 3b (direction along the side of the glass substrate G). . In this way, since the holding position of the glass substrate G by the holding pads 3a and 3b can be adjusted as appropriate according to the size of the glass substrate G, glass substrates G of various sizes can be easily and reliably attached. It becomes possible to hold.

また、上記の実施形態では、複数の連結部材4を所定の間隔を空けて配列したものを説明したが、図7に示すように、一枚の板状体で連結部材13を構成してもよい。なお、この場合であっても、連結部材13を透明なFRP等の樹脂で成形することで、連結部材13の外側から内側を視認することは可能となる。   In the above embodiment, a plurality of connecting members 4 are arranged at predetermined intervals. However, as shown in FIG. 7, the connecting member 13 may be configured by a single plate-like body. Good. Even in this case, it is possible to visually recognize the inside from the outside of the connecting member 13 by molding the connecting member 13 with a resin such as transparent FRP.

さらに、上記の実施形態では並列配置された複数枚のガラス基板Gのそれぞれの四角部、すなわち四つの隅角部に梱包材1を配設した例を示したが、その他に、例えばガラス基板Gの四角部のうち、三つの角部については梱包材1を配設し、他の一つの角部については保持パッドのみを適用することも可能である。なお、この場合には、梱包材1を配設する角部については適宜選択し得るものである。   Furthermore, in the above-described embodiment, the example in which the packaging material 1 is disposed in each of the square portions of the plurality of glass substrates G arranged in parallel, that is, the four corner portions, is shown. It is also possible to arrange the packing material 1 for three corners of the four corners and to apply only the holding pad to the other one corner. In this case, the corner where the packing material 1 is disposed can be selected as appropriate.
