国際公開第２００８／１０５１９０号International Publication No. 2008/105190

　ところで、従来の梱包体では、吸着パッド７を合紙４の上面に押圧する動作時、又は吸着パッド７によって合紙４を上方に持ち上げる動作時に、最後（最下部）の合紙４が緩衝部材２に対して横滑りするという問題があった。この問題は、ガラス板Ｇの取り出し工程の序盤時には積層体３の重さが重いため発生しないが、ガラス板Ｇが残り数枚となった終盤時に積層体３の重さが軽量になることに起因して多発していた。合紙４の横滑り量が大きいと、吸着パッド６とガラス板Ｇとの相対位置が大きくずれて吸着不良が発生するので、合紙４の横滑りは避けなければならない。 By the way, in the conventional package, when the suction pad 7 is pressed against the upper surface of the interleaving paper 4 or when the interleaving paper 4 is lifted upward by the suction pad 7, the last (lowermost) interleaving paper 4 is the buffer member. There was a problem of skidding with respect to 2. This problem does not occur at the beginning of the glass plate G take-out process because the weight of the laminated body 3 is heavy, but the weight of the laminated body 3 becomes light at the end of the time when the remaining number of glass sheets G is few. It was caused frequently. If the slippage amount of the slip sheet 4 is large, the relative position between the suction pad 6 and the glass plate G is greatly shifted and a suction failure occurs. Therefore, the slippage of the slip sheet 4 must be avoided.

　また、従来の梱包体では、最後の合紙４が積層体３の重さによって緩衝部材２に密着する場合がある。このため、最後の合紙４と緩衝部材２との密着力が、吸着パッド７によって最後の合紙４を上方に持ち上げる力より勝っている場合には、最後の合紙４を緩衝部材２から円滑に取り出すことができないという問題があった。すなわち、吸着パッド７から最後の合紙４が外れたり、最後の合紙４が破れたりしていた。 In the conventional package, the last interleaf 4 may be in close contact with the buffer member 2 due to the weight of the laminate 3. For this reason, when the adhesion force between the last interleaf paper 4 and the buffer member 2 is higher than the force that lifts the last interleaf paper 4 upward by the suction pad 7, the last interleaf paper 4 is removed from the buffer member 2. There was a problem that it could not be removed smoothly. That is, the last slip sheet 4 has come off from the suction pad 7 or the last slip sheet 4 has been torn.

　本発明は、このような事情に鑑みてなされたもので、積層体からシートを取り出す際に最後のシートが緩衝部材に対して横滑りするのを防止し、かつ積層体の最後のシートを緩衝部材から円滑に取り出すことができる板状体の梱包体を提供することを目的とする。 The present invention has been made in view of such circumstances, and prevents the last sheet from slipping with respect to the buffer member when the sheet is taken out from the laminate, and the last sheet of the laminate is the buffer member. It aims at providing the package of the plate-shaped body which can be taken out smoothly from.

　本発明の一態様は、前記目的を達成するために、板状体とシートとが交互に水平に積層してなる積層体と、前記積層体が前記シートを介して載置される板状の緩衝部材を備えた梱包パレットと、を有し、前記積層体が前記梱包パレットに梱包されてなる梱包体において、ＪＩＳ　Ｋ　７１２５：１９９９に準拠して測定される前記シートと前記緩衝部材との間の静摩擦係数が０．２～０．８であることを特徴とする板状体の梱包体を提供する。 In one embodiment of the present invention, in order to achieve the above object, a laminated body in which plate-like bodies and sheets are alternately and horizontally laminated, and a plate-like body on which the laminated body is placed via the sheet A packing pallet provided with a buffer member, wherein the laminate is packed on the packing pallet, and between the sheet and the buffer member measured in accordance with JIS K 7125: 1999 The plate-like package is characterized by having a static friction coefficient of 0.2 to 0.8.

　本発明の一態様によれば、シートの緩衝部材との間の静摩擦係数が０．２未満であると、静摩擦係数が小さ過ぎるため、積層体からシートを取り出す際に最後のシートが緩衝部材に対して横滑りすることを実験にて突き止めた。また、静摩擦係数が０．８を超えると、静摩擦係数が大き過ぎるため、積層体の最後のシートを緩衝部材から取り出す際に、最後のシートが吸着パッドから外れたり、最後のシートが破れたりした。 According to one aspect of the present invention, if the coefficient of static friction between the sheet and the buffer member is less than 0.2, the coefficient of static friction is too small, so that when the sheet is taken out from the laminate, the last sheet becomes the buffer member. On the other hand, it was confirmed by an experiment that the skid slipped. In addition, when the static friction coefficient exceeds 0.8, the static friction coefficient is too large, so when the last sheet of the laminate is taken out from the buffer member, the last sheet is detached from the suction pad or the last sheet is torn. .

　したがって、シートと緩衝部材との間の静摩擦係数を０．２～０．８に規定することによって、積層体からシートを取り出す際に最後のシートが緩衝部材に対して横滑りするのを防止でき、かつ積層体の最後のシートを緩衝部材から円滑に取り出すことが可能となる。 Therefore, by defining the coefficient of static friction between the sheet and the buffer member as 0.2 to 0.8, it is possible to prevent the last sheet from slipping with respect to the buffer member when taking out the sheet from the laminate, And it becomes possible to take out the last sheet | seat of a laminated body smoothly from a buffer member.

　実施の形態の積層体１４では、ガラス板Ｇとガラス板Ｇとの間に介在されるシートとして合紙１２を例示したが、合紙１２に限定されるものではない。例えば、樹脂フィルム、及び発泡緩衝材等のシートであっても合紙１２に代えて適用できる。 In the laminated body 14 of the embodiment, the slip sheet 12 is exemplified as a sheet interposed between the glass plate G and the glass plate G, but is not limited to the slip sheet 12. For example, a sheet such as a resin film and a foam cushioning material can be used instead of the interleaf paper 12.

　シートとして合紙１２を使用する場合には、合紙１２の原料はバージンパルプが好ましいが、セルロース等を含有している原料を用いてもよい。また、合紙１２は、平滑度１８秒以下（ＪＩＳ　Ｐ　８１１９，１９７６）の粗面を有し、接触面積を小さくして合紙１２の樹脂分がガラス板Ｇに転写されてガラス面に紙肌模様、焼け、汚れ等が生じないような紙質が選択されて使用される。更に合紙１２の樹脂分は、０．０５質量％以下（ＪＩＳ　Ｐ　８２０５，１９７６）であり、上述した紙面粗さとの複合効果によってガラス板Ｇ自体の品質に悪影響を及ぼさないような紙質が選択されて使用される。 When using the interleaf 12 as a sheet, the raw material of the interleaf 12 is preferably virgin pulp, but a raw material containing cellulose or the like may be used. Further, the interleaf paper 12 has a rough surface with a smoothness of 18 seconds or less (JIS P 8119, 1976), the contact area is reduced, and the resin content of the interleaf paper 12 is transferred to the glass plate G so that the paper surface is covered with paper.

　〈梱包パレット１６〉
　梱包パレット１６は、図２に示すように平面視矩形状の台座２０、板状の緩衝部材２２、及び合紙押さえ部材２４を主として構成される。また、梱包パレット１６の四隅部には、パレット積層部材を構成する柱状のガイド部材２６、２６…が立設されているので、梱包パレット１６を縦方向に複数段積層して運搬する場合に有利である。 <Packing pallet 16>
As shown in FIG. 2, the packing pallet 16 mainly includes a pedestal 20 having a rectangular shape in plan view, a plate-shaped buffer member 22, and an interleaf sheet pressing member 24. Further, column-shaped guide members 26, 26,... Constituting the pallet stacking member are erected at the four corners of the packing pallet 16, which is advantageous when the packing pallet 16 is stacked and transported in the vertical direction. It is.

　台座２０は、重量、剛性、及びコストの面からアルミニウム製又はアルミニウム合金製である。また、台座２０の全側面には図１、図２の如く、フォークリフト(図示せず)のフォークが挿入されるフォークリフト用開口部２８が台座２０の一側面につき２箇所形成されている。これにより、梱包パレット１６に対して台座２０の縦横側面のいずれの方向からもフォークリフトのフォークを挿入できる。 The pedestal 20 is made of aluminum or aluminum alloy in terms of weight, rigidity, and cost. Further, as shown in FIGS. 1 and 2, forklift openings 28 into which forks of a forklift (not shown) are inserted are formed at two positions on one side of the pedestal 20. As a result, the fork of the forklift can be inserted into the packing pallet 16 from any of the vertical and horizontal side surfaces of the base 20.

　台座２０の上面には、受け皿３０を介して矩形状の緩衝部材２２が配置される。この緩衝部材２２の上面に最下部に位置した合紙１２を介して積層体１４が載置される。緩衝部材２２としては、発泡ポリウレタン又は発泡ポリプロピレン等を素材とするクッション性を有する部材であればよく、特に限定されるものではない。 A rectangular buffer member 22 is disposed on the upper surface of the pedestal 20 via a tray 30. The laminated body 14 is placed on the upper surface of the buffer member 22 with the interleaf paper 12 positioned at the lowermost part. The buffer member 22 may be any member having cushioning properties made of foamed polyurethane or foamed polypropylene, and is not particularly limited.

　合紙押さえ部材２４は、図１の如く受け皿３０の４辺の各辺に所定の間隔をもって例えば２個ずつ配置され、ねじ３２、３２によって受け皿３０に固定されている。また、ねじ３２によって合紙押さえ部材２４を締結していくと、ガラス板Ｇは合紙押さえ部材２４によって側面から押圧されて、各４辺の合紙押さえ部材２４、２４…によって４辺が挟持される。また、合紙押さえ部材２４によって、ガラス板Ｇの各４辺からはみ出している合紙１２がガラス板Ｇの端面方向に押圧される。以上が梱包体１０の構成である。 As shown in FIG. 1, for example, two slip sheet pressing members 24 are arranged at predetermined intervals on each of the four sides of the tray 30, and are fixed to the tray 30 by screws 32 and 32. When the slip sheet pressing member 24 is fastened by the screw 32, the glass sheet G is pressed from the side surface by the slip sheet pressing member 24, and the four sides are sandwiched by the four side slip sheet pressing members 24, 24. Is done. In addition, the slip sheet 12 protruding from each of the four sides of the glass plate G is pressed in the direction of the end face of the glass plate G by the slip sheet pressing member 24. The above is the configuration of the package 10.

　〔梱包体１０の特徴〕
　梱包体１０の特徴は、ＪＩＳ　Ｋ　７１２５：１９９９又はＩＳＯ　８２９５：１９９５に準拠して測定される合紙１２と緩衝部材２２との間の静摩擦係数を０．２～０．８に規定した点にある。 [Characteristics of the package 10]
The package 10 is characterized in that the coefficient of static friction between the slip sheet 12 and the buffer member 22 measured in accordance with JIS K 7125: 1999 or ISO 8295: 1995 is defined as 0.2 to 0.8. is there.

　図３は、ＪＩＳ　Ｋ　７１２５：１９９９に準拠した静摩擦係数の測定装置４０を示した斜視図である。 FIG. 3 is a perspective view showing a static friction coefficient measuring device 40 based on JIS K 7125: 1999.

　図３の測定装置４０によれば、合紙１２を所定のサイズに切断したサンプル片４２の上面に、緩衝部材２２を所定のサイズに切断したサンプル片４４を載置し、かつサンプル片４４の上面に２００ｇ（１．９６Ｎ）の荷重体４６を載置し、サンプル片４４を牽引部材４８によって矢印Ｃの如く水平方向に牽引し、牽引時に発生する力をロードセル５０によって測定する。 3, the sample piece 44 obtained by cutting the buffer member 22 into a predetermined size is placed on the upper surface of the sample piece 42 obtained by cutting the interleaf paper 12 into a predetermined size. A load body 46 of 200 g (1.96 N) is placed on the upper surface, the sample piece 44 is pulled in the horizontal direction as indicated by arrow C by the pulling member 48, and the force generated at the time of pulling is measured by the load cell 50.

　前記力は、直線的に増加していき最大荷重に到達する。この最大荷重が静摩擦力Ｆｓであり、この静摩擦力ＦｓをＦｐ（荷重体４６の質量によって生じる法線力：１．９６Ｎ）で乗算（Ｆｓ／Ｆｐ）することによって静摩擦係数を算出する。以上が測定装置４０の概要である。 The force increases linearly and reaches the maximum load. This maximum load is the static friction force Fs, and the static friction coefficient is calculated by multiplying this static friction force Fs by Fp (normal force generated by the mass of the load body 46: 1.96 N) (Fs / Fp). The above is the outline of the measuring apparatus 40.

　本願発明者らは、従来の梱包体の問題を解決するための手段として、積層体１４の最後の合紙１２と梱包パレット１６の緩衝部材２２との間の静摩擦係数に着目した。そして、最後の合紙１２が緩衝部材２２に対して横滑りするのを防止するための好適な静摩擦係数、及び最後の合紙１２を緩衝部材２２から円滑に取り出すための好適な静摩擦係数を、実機（梱包体１０）及び図３の測定装置４０を使用した実験にて導き出した。 The inventors of the present application focused on the coefficient of static friction between the last interleaf 12 of the laminate 14 and the buffer member 22 of the packing pallet 16 as a means for solving the problems of the conventional package. Then, a suitable static friction coefficient for preventing the last slip sheet 12 from sliding sideways with respect to the buffer member 22 and a suitable static friction coefficient for smoothly removing the last slip sheet 12 from the buffer member 22 are obtained. It was derived in an experiment using the (packaging body 10) and the measuring device 40 of FIG.

　すなわち、静摩擦係数が０．２以上であると、静摩擦係数が小さ過ぎないため、積層体１４から合紙１２を取り出す際に最後の合紙１２が緩衝部材２２に対して横滑りしないことを実験にて突き止めた。また、静摩擦係数が０．８以下であると、静摩擦係数が大き過ぎないため、積層体１４の最後の合紙１２を緩衝部材２２から取り出す際に、最後の合紙１２から吸着パッド７（図５参照）が外れたり、最後の合紙１２が破れたりしないことを実験にて突き止めた。 That is, when the coefficient of static friction is 0.2 or more, the coefficient of static friction is not too small. Therefore, when taking out the slip sheet 12 from the laminate 14, the last slip sheet 12 does not skid with respect to the buffer member 22 in the experiment. I found out. If the static friction coefficient is 0.8 or less, the static friction coefficient is not too large. Therefore, when the last interleaf 12 of the laminate 14 is taken out from the buffer member 22, the suction pad 7 (see FIG. 5)) and the final interleaf paper 12 was not torn.

　したがって、合紙１２と緩衝部材２２との間の静摩擦係数を０．２～０．８に規定することによって、積層体１４から合紙１２を取り出す際に最後の合紙１２が緩衝部材２２に対して横滑りするのを防止でき、かつ積層体１４の最後の合紙１２を緩衝部材２２から円滑に取り出すことが可能となる。よって、従来の問題を解消できる。 Therefore, by defining the coefficient of static friction between the interleaf paper 12 and the buffer member 22 to 0.2 to 0.8, the last interleaf paper 12 becomes the buffer member 22 when the interleaf paper 12 is taken out from the laminate 14. On the other hand, it is possible to prevent a side slip, and it is possible to smoothly take out the last interleaf 12 of the laminated body 14 from the buffer member 22. Therefore, the conventional problem can be solved.
