ガラス板への合紙の積層方法およびガラス板積層体からの合紙の除去方法Method for laminating interleaving paper on glass plate and method for removing interleaving paper from glass plate laminate
　本発明は、複数枚のガラス板と合紙とが積層されたガラス板積層体を組立てる際のガラス板への合紙の積層方法、および合紙を挟んでガラス板が積層されたガラス板積層体から合紙を除去する方法に関する。 The present invention relates to a method for laminating a slip sheet on a glass plate when assembling a glass plate laminate in which a plurality of glass plates and slip sheets are laminated, and a glass plate stack in which glass plates are stacked with the slip sheet interposed therebetween. The present invention relates to a method for removing slip sheets from a body.
　液晶ディスプレイ装置、有機ＥＬディスプレイ装置やプラズマディスプレイ装置等のフラットディスプレイ装置で使用される大寸法のガラス板は、保管時、梱包時、あるいは次の工程への移送時に、ガラス板同士が直接接触しないように、隣り合うガラス板の間に合紙を挟んで、キズ発生、破損やガラス板同士の密着等を防止している。このようなガラス板積層体を組立てる際のガラス板面への合紙の積層工程は、例えば、斜め縦積みパレットに斜めに立て掛けられたガラス板の表面に、あるいは平積みパレットに平置きされたガラス板の表面に、吸着パッドにより合紙を吸着して合紙を一枚ずつ移動してガラス板に重ねることによって行なわれる。また、このように、保管、あるいは梱包されたガラス板を次の工程で処理する場合、合紙を挟んでガラス板が積層されたガラス板積層体から吸着パッドを有するロボットや専用機によって合紙を１枚ずつ取り出すことが行なわれる。 Large-sized glass plates used in flat display devices such as liquid crystal display devices, organic EL display devices, and plasma display devices are not in direct contact with each other during storage, packaging, or transfer to the next process. In this way, a slip sheet is sandwiched between adjacent glass plates to prevent scratches, breakage, adhesion between the glass plates, and the like. The lamination process of the slip sheet on the glass plate surface when assembling such a glass plate laminate is, for example, placed on the surface of the glass plate leaning diagonally on the oblique vertical pallet or on the flat pallet It is carried out by adsorbing the interleaving paper on the surface of the glass plate with an adsorbing pad, moving the interleaving paper one by one and stacking it on the glass plate. In addition, when processing a glass plate that has been stored or packed in this way in the next step, a slip sheet is sandwiched by a robot or a dedicated machine having a suction pad from a glass plate laminate in which the glass plates are laminated with the slip sheet interposed therebetween. Are taken out one by one.
　上記したようなガラス板積層体から合紙を除去する方法として、特許文献１には、アームと、前記アームの先端部に係合されたヘッドと、前記アームを移動させる移動機構とを備え、前記ヘッドが、挟持機構を少なくとも１つ備える合紙除去装置を用い、前記移動機構を、前記ヘッドがガラス板に接近する方向に前記アームを移動させ、前記挟持機構が、最表面の合紙を挟持し、前記移動機構が、前記ヘッドがガラス板から離れる方向に前記アームを移動させ、その後前記挟持機構が、前記挟持された合紙を解放して当該合紙をガラス板から取り除く合紙除去方法について開示されている。 As a method for removing the slip sheet from the glass plate laminate as described above, Patent Document 1 includes an arm, a head engaged with the tip of the arm, and a moving mechanism for moving the arm. The head uses a slip sheet removing device having at least one sandwiching mechanism, the moving mechanism moves the arm in a direction in which the head approaches the glass plate, and the sandwich mechanism removes the outermost slip sheet. Interleaving is performed, and the moving mechanism moves the arm in a direction in which the head separates from the glass plate, and then the interleaving mechanism releases the interleaving paper and removes the interleaving paper from the glass plate. A method is disclosed.
　また、ガラス板積層体から合紙を除去する装置として、特許文献２には、回動可能に設けられた一対の保持片と、この保持片を進退自在に支持した支持部材と、この支持部材を進退させる駆動装置とを設け、前記保持片の先端部が回動する円弧上に前記基板表面の合紙が位置する状態で、前記支持部材の移動を停止させ、前記保持片を回動させて前記合紙を一対の保持片で挟持し、前記支持部材を退避させ、前記合紙を前記基板から剥離する合紙剥離装置について開示されている。 Further, as an apparatus for removing slip sheets from a glass plate laminate, Patent Document 2 discloses a pair of holding pieces that are rotatably provided, a support member that supports the holding pieces so as to be movable forward and backward, and the support member.

In the process of removing the interleaving paper from the glass plate laminate, it is possible to adsorb and hold the interleaving paper of the glass plate laminate one by one with the suction pad in the process of removing the interleaving paper from the glass plate laminate. As a result of repeated experiments, paying attention to various conditions that can be removed from the glass plate without tearing the interleaving paper, and that the removed interleaving paper can be moved to the predetermined interleaving paper placement place without any problem It has been found that there is a large correlation between the absolute humidity of the environmental atmosphere in the process of laminating the slip sheet on the glass plate and the absolute humidity of the environmental atmosphere in the process of removing the slip sheet from the glass sheet laminate.

　以下、本発明のガラス板への合紙の積層方法について、図１を参照しながら説明する。 Hereinafter, the method for laminating the slip sheet on the glass plate of the present invention will be described with reference to FIG.
　本発明のガラス板への合紙の積層工程は、例えば、ガラス板製造ラインにて成形されたリボン状のガラス板を、所定の寸法の矩形状のガラス板となるように切断し、ガラス板を採板場所まで移送し、この場所にてガラス板用パレットにガラス板を載置する際に、ガラス板の１枚ごとに、キズ防止、破損防止のための合紙を１枚ずつ積層するということで行なわれる。このようなガラス板への合紙の積層工程は、上記したようなガラス板製造ラインばかりでなく、洗浄され、検査されたガラス板を次工程内に移送する際においても、また客先への出荷に当たり梱包する際にも、ガラス板用パレットに載置するときに、同様なガラス板への合紙の積層工程が行なわれる。 The lamination process of the slip sheet on the glass plate of the present invention includes, for example, cutting a ribbon-shaped glass plate formed in a glass plate production line so as to become a rectangular glass plate of a predetermined size, When the glass plate is placed on the glass plate pallet at this location, the slip sheets for preventing scratches and damage are laminated one by one for each glass plate. That is done. Such a process of laminating slip sheets on a glass plate is not only for the glass plate production line as described above, but also when the cleaned and inspected glass plate is transferred into the next process, and to the customer. When packing on shipment, a similar process of laminating slip sheets on a glass plate is performed when placing the product on a glass plate pallet.
　例えば、本発明のガラス板への合紙の積層工程は、図１に示されるように、基台部２１と、背面部２２と、傾斜台座部２３と、傾斜背もたれ部２４とから基本的に構成された、斜め縦置きタイプのガラス板用パレット２５に対し、吸着パッド３０を先端に有するロボットハンドを備えたガラス板ハンドリング装置（図示せず）により、合紙１０とガラス板Ｇとをそれぞれ交互に吸着して積層してゆき、複数枚のガラス板の間に合紙が挟まれたガラス板積層体２０が組み立てられる。このタイプにおいては、水平面に対し少し傾斜している傾斜台座部２３（例えば、水平面に対し７０°～７４°傾斜しているガラス板の端面を支持する傾斜台座部）にガラス板Ｇの下端が載り、傾斜台座部２３の上面と直交し鉛直面に対して少し傾斜している傾斜背もたれ部２４に、積層されていくガラス板Ｇ群の背面部分がもたれ掛る。 For example, as shown in FIG. 1, the lamination process of the slip sheet on the glass plate of the present invention basically includes a base portion 21, a back surface portion 22, an inclined pedestal portion 23, and an inclined backrest portion 24. The slip sheet 10 and the glass sheet G are respectively separated by a glass plate handling device (not shown) provided with a robot hand having a suction pad 30 at the tip of the slanted vertical type glass plate pallet 25 configured. By alternately adsorbing and laminating, a glass plate laminate 20 in which a slip sheet is sandwiched between a plurality of glass plates is assembled. In this type, the lower end of the glass plate G is attached to the inclined pedestal 23 that is slightly inclined with respect to the horizontal plane (for example, the inclined pedestal that supports the end surface of the glass plate inclined 70 ° to 74 ° with respect to the horizontal plane). The back surface portion of the laminated glass sheet G rests on the inclined backrest portion 24 that is placed and orthogonal to the upper surface of the inclined pedestal portion 23 and slightly inclined with respect to the vertical plane.
　図１に示した例においては、まず吸着パッド３０を先端に有するロボットハンドを備えたガラス板ハンドリング装置がガラス板積層体組立用の合紙の供給のため、合紙の置き場に合紙を取りにゆき、吸着パッドで合紙を吸着・把持してガラス板用パレット２５の傾斜背もたれ部２４に掛け、吸着を解除し、次いでロボットハンドはガラス板積層体組立用のガラス板の供給のためのガラス板の置き場、あるいはガラス板が搬送されてくる位置に、ガラス板を取りにゆき、吸着パッドでガラス板を吸着・把持してガラス板用パレット２５の合紙が掛けられた傾斜背もたれ部２４に積層し、吸着を解除し、合紙面にガラス板を積層する。次いで、次の合紙の積層のため、上記するロボットハンドがガラス板積層体組立用の合紙の供給のための合紙の置き場に再度合紙を取りにゆき、吸着パッドで合紙を吸着、把持してガラス板用パレット２５の傾斜背もたれ部２４に立て掛けられたガラス板に掛け、吸着を解除し、次いで、次のガラス板の積層のため、ロボットハンドはガラス板積層体組立用のガラス板の供給のためのガラス板の置き場、あるいはガラス板が搬送されてくる位置に再度ガラス板を取りにゆき、吸着パッドでガラス板を吸着、把持して吸着を解除し、ガラス板に合紙が掛けられた合紙面にガラス板を積層する。この操作を繰り返すことによって、ガラス板積層体２０が組み立てられる。 In the example shown in FIG. 1, first, a glass plate handling apparatus equipped with a robot hand having a suction pad 30 at the tip takes the slip sheet at the slip sheet storage place to supply slip sheets for assembling the glass plate laminate. Then, the suction pad sucks and grips the slip sheet and puts it on the inclined back portion 24 of the glass plate pallet 25 to release the suction. Then, the robot hand is used to supply the glass plate for assembling the glass plate laminate. An inclined backrest 24 in which a glass plate is moved to a place where the glass plate is placed or where the glass plate is conveyed, and the glass plate is adsorbed and gripped by a suction pad, and a slip sheet of the glass plate pallet 25 is hung. The glass sheet is laminated on the interleaf sheet surface. Next, to stack the next slip, the robot hand mentioned above goes back to the slip sheet storage for supplying the slip for assembling the glass laminate and picks up the slip with the suction pad. Then, the robot hand holds the glass plate for assembling the glass plate laminate for stacking the next glass plate by holding it and hanging it on the glass plate standing on the inclined backrest portion 24 of the pallet 25 for glass plate. Go back to the glass plate storage for supplying the plate, or to the position where the glass plate is transported, pick up the glass plate with the suction pad, hold the glass plate to release the suction, and insert the paper on the glass plate A glass plate is laminated on the interleaving paper surface. By repeating this operation, the glass plate laminate 20 is assembled.
　次に、ガラス板積層体からの合紙の除去方法について、図２を参照しながら説明する。 Next, a method for removing the slip sheet from the glass plate laminate will be described with reference to FIG.
　本発明のガラス板積層体からの合紙の除去工程は、例えば、ガラス板用パレットに載置されたガラス板積層体のガラス板を次の処理工程に移す際に、あるいはガラス積層体を開梱するなどの際に、ガラス積層体のガラス板の１枚、１枚ごとの間に挿入されたキズ防止、破損防止のための合紙を１枚ずつ取り剥がす、すなわち除去するということで行なわれる。 The interleaf removal process from the glass plate laminate of the present invention is performed, for example, when the glass plate of the glass plate laminate placed on the glass plate pallet is moved to the next processing step, or when the glass laminate is opened. When packing, etc., it is done by removing, ie removing, one sheet of glass sheet of the glass laminate to prevent scratches and damages inserted between each sheet. It is.
　例えば、本発明のガラス板積層体からの合紙の除去工程は、図２に示されるように、図１と同様な斜め縦置きタイプのガラス板用パレット２５に載置された、複数枚のガラス板Ｇと合紙１０とが積層されたガラス板積層体から、吸着パッド３０を先端に有するロボットハンドを備えたガラス板ハンドリング装置（図示せず）により、合紙１０とガラス板Ｇとをそれぞれ交互に吸着、把持して、合紙は、合紙置き場に移送され、ガラス板Ｇは、ガラス板Ｇの次の工程のための載置場所に移送される。 For example, as shown in FIG. 2, the step of removing the interleaf from the glass plate laminate of the present invention includes a plurality of sheets placed on an oblique vertical glass plate pallet 25 similar to FIG. From the glass plate laminate in which the glass plate G and the interleaf paper 10 are laminated, the interleaf paper 10 and the glass plate G are obtained by a glass plate handling device (not shown) provided with a robot hand having a suction pad 30 at the tip. By alternately adsorbing and gripping each, the slip sheet is transferred to the slip sheet storage place, and the glass plate G is transferred to the placement place for the next step of the glass plate G.
　図２に示した例においては、まずガラス板用パレット２５の傾斜背もたれ部２４に斜め縦置きされたガラス板積層体２０に対して最外表面の合紙１０を取り剥がすため、吸着パッド３０を先端に有するロボットハンドを備えたガラス板ハンドリング装置が操作されて、吸着パッド３０が合紙を取りにゆき、吸着パッド３０で合紙を吸着・把持して、ガラス板積層体２０から合紙１０を除去し、除去された合紙を合紙の置き場に移送する。 In the example shown in FIG. 2, first, the suction pad 30 is used to peel off the outermost interleaf paper 10 from the glass plate laminate 20 obliquely placed vertically on the inclined backrest portion 24 of the glass plate pallet 25. A glass plate handling device having a robot hand at the tip is operated so that the suction pad 30 picks up the slip sheet, and the suction pad 30 sucks and grips the slip sheet. , And the removed slip sheet is transferred to a slip sheet storage area.
　次いで、除去された合紙の下層のガラス板を取り出すため、吸着パッド３０が当該ガラス板Ｇを迎えにゆき、当該吸着パッド３０が当該ガラス板Ｇを吸着・把持して、ガラス板積層体２０からガラス板を取り出し、取り出されたガラス板を、ガラス板の置き場、あるいはガラス板の次の工程のステーションに移送する。次いで、次の合紙の除去のため、吸着パッド３０が合紙を取りにゆき、吸着パッド３０で合紙を吸着・把持して、ガラス板積層体２０から合紙を除去し、除去された合紙を合紙の置き場に移送する。次いで、次のガラス板の取り出しのため、吸着パッド３０が当該ガラス板Ｇを吸着・把持して、ガラス板積層体２０からガラス板を取り出し、取り出されたガラス板をガラス板の置き場、あるいはガラス板の次の工程のステーションに移送する。この操作を繰り返すことによって、ガラス板積層体２０から合紙が除去され、またガラス板が取り出される。 Next, in order to take out the glass plate under the removed slip sheet, the suction pad 30 picks up the glass plate G, and the suction pad 30 sucks and grips the glass plate G. The glass plate is taken out of the glass plate, and the taken-out glass plate is transferred to a place where the glass plate is placed or to a station for the next step of the glass plate. Next, for the removal of the next slip sheet, the suction pad 30 went to take the slip sheet, sucked and gripped the slip sheet with the suction pad 30, and the slip sheet was removed from the glass plate laminate 20 and removed. The slip is transferred to the slip paper storage area. Next, for taking out the next glass plate, the suction pad 30 sucks and holds the glass plate G, takes out the glass plate from the glass plate laminate 20, and the taken-out glass plate is placed in the glass plate place or glass. Transfer to the next processing station on the board. By repeating this operation, the slip sheet is removed from the glass plate laminate 20 and the glass plate is taken out.
　なお、図１および図２においては、斜め縦置きタイプのガラス板用パレットの例を示したが、ガラス板を平置きして重ねる平置きタイプのガラス板用パレットにおいても同様に使用できる。 1 and 2 show an example of a slanting vertical type glass plate pallet, it can be used in a flat type glass plate pallet in which glass plates are laid flat and stacked.
　上記したガラス板積層体２０は、ガラス板を出荷する際であれば、ガラス板梱包体であり、ガラス板を次の工程へ移送するために、保管する際であれば、ガラス板保管体と称することもできる。 The glass plate laminate 20 described above is a glass plate package if the glass plate is shipped, and if the glass plate is stored for transporting the glass plate to the next step, It can also be called.
　図示した例は、ガラス板Ｇおよび合紙１０の大きさに応じて、ガラス板または合紙の上辺側領域、中間領域、下辺側領域を吸着して把持することができるように、３列の吸着パッド列を有するロボットハンドを備えたガラス板ハンドリング装置であるが、ガラス板Ｇおよび合紙１０の大きさに応じて、吸着パッド列は、１列であっても２列であっても、４列以上など適宜のパターンを採用してもよい。同様に各列における吸着パッドの数も、ガラス板Ｇおよび合紙１０の大きさに応じて適宜の数が採用される。また、吸着パッドとしては、ガラス板Ｇおよび合紙の両方に適用できるものが、ハンドリング装置の構造を複雑にしないという面から好ましいが、ガラス板Ｇおよび合紙１０のそれぞれに対応する最適な構造を有する吸着パッドを使用してもよい。 In the illustrated example, three rows are arranged so that the upper side region, the middle region, and the lower side region of the glass plate or the slip sheet can be adsorbed and gripped according to the sizes of the glass plate G and the slip sheet 10. Although it is a glass plate handling device provided with a robot hand having a suction pad row, depending on the size of the glass plate G and the interleaf paper 10, the suction pad row may be one row or two rows, An appropriate pattern such as four or more rows may be adopted. Similarly, as the number of suction pads in each row, an appropriate number is adopted according to the sizes of the glass plate G and the interleaf paper 10. Further, the suction pad that can be applied to both the glass plate G and the slip sheet is preferable from the viewpoint of not complicating the structure of the handling device, but the optimum structure corresponding to each of the glass plate G and the slip sheet 10 is preferable. You may use the suction pad which has.
　ガラス板Ｇまたは合紙１０を吸着パッドにより把持する際の吸着力は、ガラス板の大きさ、重量、厚さ等のガラス板Ｇの仕様、また合紙１０の材質、厚さ等によって最適な範囲が選択される。 The adsorption force when the glass plate G or the interleaf paper 10 is gripped by the adsorption pad is optimum depending on the specifications of the glass plate G such as the size, weight and thickness of the glass plate, and the material and thickness of the interleaf paper 10. A range is selected.
　また、ガラス板への合紙の積層工程において、ガラス板Ｇ面への合紙１０の積層が全面に渡って均一に行なわれるように、ガラス板Ｇ面へ積層された合紙１０の面に対し、風を送る空気吹出し装置を付設しても良い。 Further, in the step of laminating the slip sheet on the glass plate, the slip sheet 10 on the surface of the glass plate G is laminated on the surface of the slip sheet 10 so that the slip sheet 10 is uniformly laminated over the entire surface. On the other hand, you may attach the air blowing apparatus which sends a wind.
　また、ガラス板積層体からの合紙の除去工程において、合紙の除去が容易となるように、ガラス板Ｇと合紙１０との間に、風を送る空気吹出し装置を付設しても良いし、または合紙１０の除去が容易となるように、ガラス板Ｇの辺部からはみ出した合紙１０の端部を把持して合紙１０の移動が容易となるように、合紙１０の端部を把持する把持手段を付設しても良い。 Further, in the process of removing the slip sheet from the glass plate laminate, an air blowing device for sending wind may be provided between the glass plate G and the slip sheet 10 so that the slip sheet can be easily removed. In order to facilitate the removal of the slip sheet 10, the end of the slip sheet 10 protruding from the side of the glass plate G is gripped so that the slip sheet 10 can be easily moved. You may attach the holding means which hold | grips an edge part.
　本発明においては、上記したガラス板へ合紙を積層する際、ガラス板面への合紙の積層工程が行なわれる環境雰囲気を７ｇ／ｍ３超、１３ｇ／ｍ３未満の絶対湿度の範囲とすることを特徴する。 In the present invention, when stacking the interleaf sheet to the glass plate described above, 7 g / m 3 greater than the environmental atmosphere lamination step of interleaving paper is performed on the glass plate surface, and the range of the absolute humidity of less than 13 g / m 3 It is characterized by.
　上記した環境雰囲気が７ｇ／ｍ３以下の絶対湿度であると、合紙が乾燥しやすくなり、合紙を吸着パッドにより吸着したとき合紙が破れやすくなり、また合紙を吸着パッドにより吸着し、ガラス板に積層するときに合紙が破れやすくなり、好ましくない。 When the above-mentioned environmental atmosphere is an absolute humidity of 7 g / m 3 or less, the slip sheet is easily dried, and when the slip sheet is sucked by the suction pad, the slip sheet is easily torn, and the slip sheet is sucked by the suction pad. When laminated on a glass plate, the slip sheet is easily broken, which is not preferable.
　一方、１３ｇ／ｍ３以上の絶対湿度であると、合紙が水分により合紙の腰が弱くなり、特に、斜め縦置きタイプのガラス板用パレットを使用する場合、合紙をガラス板面の積層する際に合紙が倒れやすくなり、好ましくない。 On the other hand, when the absolute humidity is 13 g / m 3 or more, the slippage of the slip sheet becomes weak due to moisture, and in particular, when a slanted vertical type glass plate pallet is used, the slip sheet is placed on the glass plate surface. The interleaving paper tends to collapse during lamination, which is not preferable.
　特に、ガラス板面への合紙の積層工程が行なわれる環境雰囲気を上記したように７ｇ／ｍ３超、１３ｇ／ｍ３未満の絶対湿度の範囲とすることにより、合紙の吸着・把持の際、ロボットハンドによって合紙に負荷がかかっても、合紙が破れるということもなく、一枚ずつ合紙をガラス板に対し積層することができ、ガラス板面への合紙の積層作業が円滑となり、合紙の破れによるガラス板面への合紙の積層作業の中断を少なくすることができ、ガラス板面への合紙の積層工程の効率化を図ることができる。 In particular, the environmental atmosphere in which the interleaving process of the slip sheet on the glass plate surface is performed is within the range of absolute humidity of more than 7 g / m 3 and less than 13 g / m 3 as described above. At this time, even if a load is applied to the slip sheet by the robot hand, the slip sheet is not torn, and the slip sheets can be laminated one by one on the glass plate, and the lamination work of the slip sheet on the glass plate surface can be performed. It becomes smooth, interruption of the lamination | stacking operation | work of the slip sheet on the glass plate surface by tearing of a slip sheet can be decreased, and the efficiency of the lamination | stacking process of the slip sheet on a glass plate surface can be aimed at.
　また、上記したガラス板面への合紙の積層工程が行なわれる環境雰囲気の温度は、通常の作業温度範囲である１５～２５℃の温度範囲が好ましい。 In addition, the temperature of the environmental atmosphere in which the above-described process of laminating the slip sheet on the glass plate surface is preferably a temperature range of 15 to 25 ° C., which is a normal working temperature range.
　なお、ガラス板面への合紙の積層工程が行なわれる環境雰囲気とは、ガラス板を合紙とともにガラス板用パレットに載置する場所の環境雰囲気をいい、ガラス板面に合紙を積層する場所において合紙が置かれている場所の環境雰囲気も含むものとする。 In addition, the environmental atmosphere in which the lamination process of the slip sheet on the glass plate surface is performed refers to the environment atmosphere where the glass plate is placed on the glass plate pallet together with the slip sheet, and the slip sheet is stacked on the glass plate surface. It also includes the environmental atmosphere of the place where the slip is placed.
　また、本発明においては、ガラス板積層体から合紙を除去する際、合紙の除去工程が行なわれる環境雰囲気を７ｇ／ｍ３超、１３ｇ／ｍ３未満の絶対湿度の範囲とすることを特徴する。 In the present invention, when removing the interleaf paper from the glass plate laminate slip sheet removal step 7 g / m 3 greater than the environmental atmosphere that takes place, that the range of the absolute humidity of less than 13 g / m 3 Characterize.
　上記した環境雰囲気が７ｇ／ｍ３以下の絶対湿度であると、合紙が乾燥しやすくなり、合紙を吸着パッドにより吸着したとき合紙が破れやすくなり、また合紙を吸着パッドにより吸着し、ガラス板から除去するとき、すなわち取り剥がすときに合紙が破れやすくなり、好ましくない。 When the above-mentioned environmental atmosphere is an absolute humidity of 7 g / m 3 or less, the slip sheet is easily dried, and when the slip sheet is sucked by the suction pad, the slip sheet is easily torn, and the slip sheet is sucked by the suction pad. When it is removed from the glass plate, that is, when it is peeled off, the slip sheet is easily broken, which is not preferable.
　一方、１３ｇ／ｍ３以上の絶対湿度であると、合紙が水分により合紙の腰が弱くなり、特に、斜め縦置きタイプのガラス板用パレットを使用する場合、ガラス板積層体から合紙を除去する際に合紙が倒れやすくなり、好ましくない。 On the other hand, when the absolute humidity is 13 g / m 3 or more, the slip of the slip sheet becomes weak due to moisture, and in particular, when using a slanted vertical type glass plate pallet, the slip sheet is made from the glass plate laminate.
