Description

積層体パレット一体品、及びパレットLaminated pallets and pallets
　本発明は、積層体パレット一体品、及びパレットに関する。 The present invention relates to a laminated pallet integrated product and a pallet.
　近年、フラットパネルディスプレイ用ガラス基板の大型化及び薄肉化に伴い、ガラス基板の梱包に際しては、ガラス基板を縦姿勢で積層した状態で行う場合がある。また、ガラス基板を縦姿勢で積層した状態で梱包するためのパレットとしては、複数のガラス基板を縦姿勢で積層してなる積層体の底辺を支持する底辺支持部と、積層体の背面を支持する背面支持部と、背面支持部と積層体との間に配設される緩衝板とを備えたものが公知である（例えば、特許文献１を参照）。なお、本明細書において、縦姿勢は、ガラス基板の表面が鉛直面と平行な垂直姿勢と、ガラス基板の表面が鉛直面に対して傾斜した傾斜姿勢を含むものとする。 In recent years, as glass substrates for flat panel displays have become larger and thinner, packing of the glass substrates may be performed in a state where the glass substrates are stacked in a vertical posture. In addition, as a pallet for packing glass substrates stacked in a vertical position, a bottom support portion that supports a bottom of a stacked body formed by stacking a plurality of glass substrates in a vertical position, and supports a back surface of the stacked body. There is a known device including a back support portion to be provided and a buffer plate disposed between the back support portion and the laminate (for example, see Patent Document 1). In this specification, the vertical posture includes a vertical posture in which the surface of the glass substrate is parallel to the vertical plane, and an inclined posture in which the surface of the glass substrate is inclined with respect to the vertical plane.
　また、この種の積層体は、上記構成のパレット上で梱包された状態で、ガラスメーカーから例えばパネルメーカーなどに納入された後、アンパッカー装置と呼ばれる開梱装置で、パレット上からガラス基板を取出す方式が主流になっている。この際、アンパッカー装置としては、ガラス基板を真空吸着するための吸着パッドと、ガラス基板の間に介在する合紙を真空吸着するための吸着パッドとを具備したものがある（何れも、特許文献２を参照）。 In addition, this kind of laminate is delivered from a glass maker to, for example, a panel maker in a state of being packed on the pallet having the above-described configuration, and then the unpacking device called an unpacker device removes the glass substrate from the pallet. The take-out method has become mainstream. At this time, as an unpacker device, there is an unpacker device having a suction pad for vacuum-sucking a glass substrate and a suction pad for vacuum-sucking an interleaf paper interposed between the glass substrates (both are patented). Reference 2).

　特許文献２のように、吸着パッドを具備したアンパッカー装置を用いて、パレット上からガラス基板を取出す場合、合紙をガラス基板上から移動させ、排出する作業が必要となる。この際、合紙の排出作業は、合紙のうちガラス基板から食み出した部分を吸着パッドで吸着して保持する動作と、保持した合紙をパレット上から退避させる動作とに大別できる。このうち、合紙を吸着保持する動作については、例えば特許文献２に記載のように、吸着パッドを押込んだときの合紙の背面側への倒れ込みを想定して、ガラス基板の積層方向に対して垂直な向きよりも斜め上方から吸着パッドを接近させる動作を採ることがある。しかしながら、この方法では、合紙及びガラス基板が残り少なくなると、合紙と背面支持部（あるいは緩衝板）までの距離が近くなるため、それまでよりも吸着パッドを押込んだ際の合紙の倒れ込み角度が小さくなる。これでは、吸着パッドの押込み角度と、合紙の倒れ込み角度とにずれが生じ、吸着パッドが合紙に対して部分的に接触することになるため、合紙を安定して吸着保持することが難しい。 を 取 When taking out a glass substrate from a pallet using an unpacker device provided with a suction pad as in Patent Document 2, it is necessary to move the interleaving paper from above the glass substrate and discharge it. At this time, the operation of discharging the slip sheet can be roughly classified into an operation of sucking and holding a portion of the slip sheet protruding from the glass substrate with a suction pad and an operation of retracting the held slip sheet from the pallet. . Among these operations, as for the operation of sucking and holding the slip sheet, as described in Patent Document 2, for example, assuming that the slip sheet falls down on the back side when the suction pad is pushed in, the stacking direction of the glass substrates is assumed. An operation of approaching the suction pad from obliquely above than the direction perpendicular to the vertical direction may be adopted. However, in this method, when the slip sheet and the glass substrate are reduced, the distance between the slip sheet and the back support portion (or the buffer plate) becomes shorter, so that the slip sheet falls down when the suction pad is pushed in. The angle becomes smaller. In this case, a difference occurs between the pressing angle of the suction pad and the falling angle of the slip sheet, and the suction pad partially contacts the slip sheet, so that the slip sheet can be stably held by suction. difficult.
　また、合紙及びガラス基板が残り少なくなると、吸着パッドによって合紙が背面支持部に強く押し付けられた状態で、吸着パッドをパレットの背面支持部に沿って斜め上方に移動させることになるため、吸着パッドで保持した合紙をパレット上から退避させると、背面支持部と合紙に作用する摩擦抵抗の増加によって合紙が吸着パッドから外れて落下するおそれが生じる。 In addition, when the interleaf paper and the glass substrate are low, the suction pad is moved obliquely upward along the back support of the pallet in a state where the interleaf is strongly pressed against the back support by the suction pad. When the interleaf held by the pad is retracted from the pallet, the interleaf may fall off the suction pad due to an increase in frictional resistance acting on the back support and the interleaf.
　以上の事情に鑑み、パレット上の積層体から合紙などの保護シートを排出するに当たって、保護シートが残り少なくなった場合においても、保護シートを安定して吸着保持できるようにすることを、解決すべき技術的課題とする。 In view of the above circumstances, it is possible to solve the problem that when protecting sheets such as slip sheets are discharged from a laminate on a pallet, the protective sheets can be stably sucked and held even when the number of remaining protective sheets decreases. Should be technical issues.
　前記技術的課題の解決は、本発明に係る積層体パレット一体品により達成される。すなわち、この一体品は、複数のガラス板と保護シートとが交互に積層された状態の積層体と、積層体を縦姿勢で保持可能であるパレットとを備えた積層体パレット一体品であって、パレットは、縦姿勢の積層体の背面側を支持する支持面を形成する背面部を有し、支持面は、ガラス板と対向する第一対向領域と、保護シートのうちガラス板から食み出した部分と対向する第二対向領域とを有し、第二対向領域に、押込みが可能な変化面が設けられている点をもって特徴付けられる。 解決 The above technical problem can be solved by the integrated pallet according to the present invention. That is, the integrated product is a laminated pallet integrated product including a laminated body in which a plurality of glass plates and protective sheets are alternately laminated, and a pallet capable of holding the laminated body in a vertical position. The pallet has a back surface portion that forms a support surface that supports the back side of the stacked body in the vertical position, and the support surface is eroded from the glass plate of the protective sheet and a first facing area facing the glass plate. It is characterized in that it has a protruding portion and a second opposing region opposing it, and the second opposing region is provided with a changeable surface that can be pushed.
　このように、本発明に係る積層体パレット一体品では、ガラス板と保護シートとを縦姿勢で交互に積層した状態の積層体の背面を支持する支持面のうち、ガラス板から食み出した保護シートと対向する領域（第二対向領域）に、押込みが可能な変化面を設けた。上記構成によれば、保護シート及びガラス板が残り少なくなると、吸着パッドによって保護シートと共に変化面が押し込まれることから、保護シートを必要十分な量だけ倒れ込ませることができる。従って、保護シートと吸着パッドとの接触状態を安定させて、確実に保護シートを吸着保持することが可能となる。また、保護シートと共に変化面が押し込まれることにより、保護シートに作用する摩擦抵抗を軽減できるので、吸着パッドから保護シートが外れて落下するのを防止できる。 As described above, in the laminated body pallet integrated product according to the present invention, the glass plate and the protection sheet protrude from the glass plate among the support surfaces that support the back surface of the laminated body in a state where the glass plate and the protective sheet are alternately laminated in the vertical position. An indentable change surface was provided in an area (second opposing area) facing the protective sheet. According to the above configuration, when the protective sheet and the glass plate become small, the change surface is pushed together with the protective sheet by the suction pad, so that the protective sheet can be fallen by a necessary and sufficient amount. Therefore, it is possible to stabilize the contact state between the protection sheet and the suction pad and securely hold the protection sheet by suction. Further, since the friction surface acting on the protective sheet can be reduced by pushing the changing surface together with the protective sheet, it is possible to prevent the protective sheet from falling off the suction pad.
　また、本発明に係る積層体パレット一体品においては、変化面が、押込みに応じて変形してもよい。 In addition, in the laminated pallet integrated product according to the present invention, the changing surface may be deformed according to the pressing.
　このように変化面を、例えばゴムやスポンジといった弾性体で形成し、押込みに応じて変形するように構成することによって、吸着パッドの押込みに応じて保護シートを必要十分な量だけ確実に倒れ込ませることができると共に、保護シートに作用する摩擦抵抗を確実に軽減できる。 In this way, the changing surface is formed of an elastic body such as rubber or sponge, and is configured to be deformed according to the pressing, so that the protective sheet can be surely fallen down by a necessary and sufficient amount according to the pressing of the suction pad. In addition, the frictional resistance acting on the protective sheet can be reliably reduced.
　また、本発明に係る積層体パレット一体品においては、変化面が、押込みに応じて移動してもよい。 In the laminated pallet integrated product according to the present invention, the changing surface may move in accordance with the pressing.
　このように変化面を、押込みに応じて移動するように構成することによって、吸着パッドの押込みに応じて保護シートを必要十分な量だけ確実に倒れ込ませることができると共に、保護シートに作用する摩擦抵抗を確実に軽減できる。 By configuring the changing surface to move in accordance with the pressing in this way, the protective sheet can be reliably fallen by a necessary and sufficient amount in accordance with the pressing of the suction pad, and acts on the protective sheet. Friction resistance can be reliably reduced.
　また、本発明に係る積層体パレット一体品においては、変化面が板状部材で形成され、板状部材は支持面と平行な軸まわりに傾動可能に構成されてもよい。 In addition, in the laminated pallet integrated product according to the present invention, the change surface may be formed by a plate-shaped member, and the plate-shaped member may be configured to be tiltable around an axis parallel to the support surface.
　このように、変化面を板状部材で形成すれば、押込んだ際の保護シートの形状が安定する。例えば板状部材の表面を平坦形状にすることで、押込んだ際の保護シートの形状が略平坦形状で安定する。よって、保護シートを吸着パッド等により安定して吸着保持することが可能となる。また、上記構成によれば、比較的容易に変化面を第二対向領域に設けることができる。よって、パレットの改良も必要最小限で済み、低コストに本技術課題の解決を図ることが可能となる。 れ ば Thus, if the changing surface is formed of a plate-like member, the shape of the protective sheet when pressed is stabilized. For example, by making the surface of the plate-shaped member flat, the shape of the protective sheet when pressed is stable in a substantially flat shape. Therefore, it is possible to stably hold the protection sheet by the suction pad or the like. Further, according to the above configuration, the changing surface can be relatively easily provided in the second facing region. Therefore, the improvement of the pallet can be minimized, and the present technical problem can be solved at low cost.
　また、本発明に係る積層体パレット一体品においては、板状部材が、押込みに抗する向きに付勢されてもよい。 Further, in the laminated pallet integrated product according to the present invention, the plate-like member may be urged in a direction against the pushing.
　上述のように板状部材を構成することで、押込みが解消されるのに伴い、板状部材を自動的に押込み前の位置又は姿勢に復帰させることができる。また、板状部材を付勢するだけであれば、非常に簡素な構成で済むため、パレットの改良コストも抑えられる。 構成 By configuring the plate-like member as described above, it is possible to automatically return the plate-like member to the position or posture before the pushing as the pushing is eliminated. Further, if only the plate-like member is urged, a very simple configuration is sufficient, so that the cost for improving the pallet can be suppressed.
　また、本発明に係る積層体パレット一体品においては、変化面が、金属で形成されてもよい。 In the laminated pallet integrated product according to the present invention, the changing surface may be formed of metal.
　このように、変化面を金属で形成することによって、ゴムやスポンジよりも摩擦抵抗を軽減することができ、変化面の耐久性も良好である。このため、長期にわたって変化面を有するパレットを使用することが可能となる。 摩擦 Thus, by forming the changing surface with metal, the frictional resistance can be reduced as compared with rubber or sponge, and the changing surface has good durability. For this reason, it is possible to use a pallet having a changing surface for a long time.
　また、本発明に係る積層体パレット一体品においては、変化面が、第一対向領域の上方に位置してもよい。 In the laminated pallet integrated product according to the present invention, the change surface may be located above the first facing region.
　変化面を第一対向領域の上方に設けることで、例えば保護シートを吸着保持した状態から持ち上げてパレット外に排出する場合に、当該変化面が有効に作用する。すなわち、パレットの周囲に比べて上方は作業スペースを確保し易いため、第一対向領域の上方に変化面を設けることで、作業スペースの面で効率よく開梱作業を行うことができると共に、その際の保護シートの排出を円滑に実施することが可能となる。 By providing the changing surface above the first facing region, the changing surface works effectively when, for example, the protective sheet is lifted from the state of being held by suction and discharged out of the pallet. That is, since it is easier to secure a work space above the periphery of the pallet, by providing a change surface above the first facing area, it is possible to efficiently perform unpacking work in terms of work space, and In this case, the protective sheet can be smoothly discharged.
　また、本発明に係る積層体パレット一体品においては、変化面が、矩形状であり、長手方向に分割されてもよい。 In the integrated pallet according to the present invention, the change surface may have a rectangular shape and may be divided in the longitudinal direction.
　吸着パッド等による保護シートの吸着保持位置（押込んだ状態の位置）は予め所定の位置に設定されているのに対し、パレット上に搭載される積層体の位置、寸法は製品ごとに少なからず相違する。そのため、矩形状の変化面の長手方向（例えば水平方向）に沿って並べた吸着パッドを一律で同じ位置で保護シートに向けて押込んだ際、その押込み量は長手方向で異なる場合がある。これに対して、本構成のように、変化面を長手方向で分割することにより、例えば変化面を板状部材で形成している場合であっても、長手方向で変化面の押込み度合い（この場合、板状部材の傾動度合い）を板状部材ごとに異ならせて、押込み量の長手方向でのばらつきを吸収することができる。 The holding position (the position where the protective sheet is pressed) of the protection sheet by the suction pad or the like is set at a predetermined position in advance, whereas the position and dimensions of the laminated body mounted on the pallet are not small for each product. Different. Therefore, when the suction pads arranged along the longitudinal direction (for example, the horizontal direction) of the rectangular changing surface are uniformly pushed toward the protective sheet at the same position, the pushing amount may differ in the longitudinal direction. On the other hand, by dividing the changing surface in the longitudinal direction as in the present configuration, for example, even when the changing surface is formed of a plate-like member, the degree of pushing of the changing surface in the longitudinal direction (this In this case, it is possible to make the degree of tilt of the plate-shaped member different for each plate-shaped member to absorb a variation in the pushing amount in the longitudinal direction.
　また、前記課題の解決は、本発明に係るパレットによっても達成される。すなわち、このパレットは、複数のガラス板と保護シートとが交互に積層された状態の積層体を縦姿勢で保持可能であるパレットであって、縦姿勢の積層体の背面側を支持する支持面を形成する背面部を備え、支持面は、ガラス板と対向する第一対向領域と、保護シートのうちガラス板から食み出した部分と対向する第二対向領域とを有し、第二対向領域には、押込みが可能な変化面が設けられている点をもって特徴付けられる。 解決 The above-mentioned object is also achieved by the pallet according to the present invention. That is, this pallet is a pallet capable of holding a stacked body in a state in which a plurality of glass plates and protective sheets are alternately stacked in a vertical position, and a support surface for supporting the back side of the stacked body in the vertical position. The support surface has a first facing region facing the glass plate, and a second facing region facing the portion of the protective sheet that protrudes from the glass plate, and has a second facing region. The region is characterized in that it has a changing surface that can be pushed.
　このように、本発明に係るパレットにおいても、ガラス板と保護シートとを縦姿勢で交互に積層した状態の積層体の背面を支持する支持面のうち、ガラス板から食み出した保護シートと対向する領域（第二対向領域）に、押込みが可能な変化面を設けた。そのため、上記構成によれば、本発明に係る一体品と同様、保護シート及びガラス板が残り少なくなると、吸着パッドによって保護シートと共に変化面が押し込まれることから、保護シートを必要十分な量だけ倒れ込ませることができる。従って、保護シートと吸着パッドとの接触状態を安定させて、確実に保護シートを吸着保持することが可能となる。また、保護シートと共に変化面が押し込まれることにより、保護シートに作用する摩擦抵抗を軽減できるので、吸着パッドから保護シートが外れて落下するのを防止できる。 Thus, also in the pallet according to the present invention, of the support surface supporting the back surface of the laminated body in a state where the glass plate and the protective sheet are alternately laminated in the vertical posture, the protective sheet protruding from the glass plate and In the facing area (second facing area), a changeable surface that can be pushed is provided. Therefore, according to the above configuration, similarly to the integrated product according to the present invention, when the protective sheet and the glass plate are reduced, the changing surface is pushed together with the protective sheet by the suction pad, so that the protective sheet falls down by a necessary and sufficient amount. I can do it. Therefore, it is possible to stabilize the contact state between the protection sheet and the suction pad and securely hold the protection sheet by suction. Further, since the friction surface acting on the protective sheet can be reduced by pushing the changing surface together with the protective sheet, it is possible to prevent the protective sheet from falling off the suction pad.
　以上に述べたように、本発明に係る積層体パレット一体品、及びパレットによれば、パレット上の積層体から合紙等の保護シートを排出するに当たって、合紙が残り少なくなった場合においても、合紙を安定して吸着保持できるようにすることが可能となる。 As described above, according to the laminated pallet integrated product and the pallet according to the present invention, when the protective sheet such as the interleaving paper is discharged from the laminated body on the pallet, even when the interleaving paper is reduced, It is possible to stably hold and hold the slip sheet.

As shown in FIGS. 1 to 3, the laminated pallet integrated product 1 includes a pallet 2 and a laminated body 3 mounted on the pallet 2.
　ここで、積層体３は、複数枚のガラス板Ｇと合紙Ｉとを縦姿勢（本実施形態では傾斜姿勢）で交互に積層してなる。本実施形態では、ガラス板Ｇと合紙Ｉはともに矩形状をなし、積層体３の最も背面側には合紙Ｉが配置されている。 Here, the laminate 3 is formed by alternately laminating a plurality of glass plates G and interleaving paper I in a vertical posture (in this embodiment, an inclined posture). In the present embodiment, both the glass plate G and the slip sheet I have a rectangular shape, and the slip sheet I is disposed on the rearmost side of the laminate 3.
　ここで、積層体３に関する諸元の一例について述べると、ガラス板Ｇの大きさは７３０ｍｍ×９２０ｍｍ～２２５０ｍｍ×２６００ｍｍ、ガラス板Ｇの厚さは３００μｍ～１１００μｍである。ガラス板Ｇとともに積層体３を構成する合紙Ｉは、例えば純パルプ紙である。合紙Ｉの大きさ（面積）は、通常、ガラス板Ｇより大きく、ガラス板Ｇ同士が直接接触しないようにガラス板Ｇと交互に配置される。これにより、ガラス板Ｇと合紙Ｉとが交互に積層された状態の積層体３が構成される。 Here, as an example of the specifications of the laminate 3, the size of the glass plate G is 730 mm × 920 mm to 2250 mm × 2600 mm, and the thickness of the glass plate G is 300 μm to 1100 μm. The interleaving paper I that forms the laminate 3 together with the glass plate G is, for example, pure pulp paper. The size (area) of the slip sheet I is usually larger than the glass sheets G, and the slip sheets I are alternately arranged with the glass sheets G so that the glass sheets G do not directly contact each other. Thereby, the laminated body 3 in a state where the glass plates G and the slip sheets I are alternately laminated is configured.
　パレット２は、積層体３の底辺３ａ側に位置する基台部４と、積層体３の背面３ｂ側に位置する背面部５とを主に備える。本実施形態では、基台部４は、積層体３の底辺３ａを支持する底辺支持部６と、底辺支持部６と積層体３との間に配設される受け板７とを有する。また、背面部５は、基台部４から起立し、積層体３の背面３ｂを支持する背面支持部８と、背面支持部８と積層体３との間に配設される緩衝板９とを有する。なお、上述した受け板７や緩衝板９は、一枚であってもよいし、複数枚であってもよい。本実施形態では、ともに一枚の受け板７と緩衝板９とが、底辺支持部６上と背面支持部８上とにそれぞれ配設されている。 The pallet 2 mainly includes a base portion 4 located on the bottom side 3a of the laminate 3 and a back portion 5 located on the back surface 3b side of the laminate 3. In the present embodiment, the base 4 includes a bottom support 6 that supports the bottom 3 a of the multilayer body 3, and a receiving plate 7 that is disposed between the bottom support 6 and the multilayer 3. Further, the rear portion 5 stands up from the base portion 4 and supports a rear surface 3b of the multilayer body 3, and a buffer plate 9 disposed between the rear support portion 8 and the multilayer body 3. Having. The number of the receiving plate 7 and the buffer plate 9 described above may be one or plural. In the present embodiment, one receiving plate 7 and one buffer plate 9 are both provided on the bottom support portion 6 and the back support portion 8, respectively.
　底辺支持部６の上面６ａは、図２に示すように、水平方向に対して所定の角度θ１（例えば５°～２５°）で、背面部５から遠ざかるにつれて上方に移行する向きに傾斜している。また、背面支持部８の前面８ａは、同じく図２に示すように、鉛直方向に対して所定の角度θ２（例えば５°～２５°）で、底辺支持部６から遠ざかるにつれて後方に移行する向きに傾斜している。この際、背面支持部８の前面８ａは、底辺支持部６の上面６ａに対して例えば略直角をなしている。また、受け板７の上面７ａが水平方向に対してなす角度は、底辺支持部６の上面６ａが水平方向に対してなす角度θ１と同じであり、緩衝板９の前面９ａのうち少なくともガラス板Ｇと対向する領域が鉛直方向に対してなす角度は、背面支持部８の前面８ａが鉛直方向に対してなす角度θ２と同じである。 As shown in FIG. 2, the upper surface 6 a of the bottom support portion 6 is inclined at a predetermined angle θ1 (for example, 5 ° to 25 °) with respect to the horizontal direction so as to move upward as the distance from the back portion 5 increases. I have. Also, as shown in FIG. 2, the front surface 8a of the back support portion 8 moves at a predetermined angle θ2 (for example, 5 ° to 25 °) with respect to the vertical direction, and moves rearward as the distance from the bottom support portion 6 increases. It is inclined. At this time, the front surface 8a of the back support 8 is, for example, substantially perpendicular to the upper surface 6a of the bottom support 6. The angle formed by the upper surface 7a of the receiving plate 7 with respect to the horizontal direction is the same as the angle θ1 formed by the upper surface 6a of the bottom support 6 with respect to the horizontal direction, and at least the glass plate of the front surface 9a of the buffer plate 9 is formed. The angle formed by the region facing G with respect to the vertical direction is the same as the angle θ2 formed by the front surface 8a of the back support 8 with respect to the vertical direction.
　なお、底辺側の緩衝板となる受け板７と、背面側の緩衝板９はともに、発泡樹脂など適度な緩衝性と機械的強度を併せ持つ材質で形成することが可能である。具体例を挙げると、受け板７と緩衝板９はともに発泡ポリプロピレンや発泡ポリエチレン、ウレタン（発泡ウレタン及び無発泡ウレタンを含む）、発泡スチレン、発泡メラミンを主たる材質として形成される。 Note that both the receiving plate 7 serving as the buffer plate on the bottom side and the buffer plate 9 on the back side can be formed of a material such as foamed resin which has both appropriate buffering properties and mechanical strength. As a specific example, both the receiving plate 7 and the buffer plate 9 are formed mainly of expanded polypropylene, expanded polyethylene, urethane (including expanded urethane and non-expanded urethane), expanded styrene, and expanded melamine.
　また、緩衝板９の幅方向寸法は、図３に示すように、背面支持部８の前面８ａの幅方向寸法よりも小さく、前面８ａの上部と両側部がそれぞれ緩衝板９から食み出した状態となっている。ここで、緩衝板９の幅方向は、縦姿勢でパレット２上に積層されたガラス板Ｇの幅方向と同じであり、ガラス板Ｇの水平方向に伸びる辺の長手方向である。また、この際、積層体３の面積は、緩衝板９の前面９ａの面積より小さく、図１に示すように積層体３をパレット２上に載置した状態では、緩衝板９の両側部が積層体３から食み出した状態となっている。また、緩衝板９の上部は、図４に示すように、ガラス板Ｇから食み出す一方で、合紙Ｉは緩衝板９の上部から食み出した位置関係となっている。従って、少なくともガラス板Ｇの全面は、合紙Ｉを介して緩衝板９の前面９ａで支持された状態となっている。 As shown in FIG. 3, the width direction dimension of the buffer plate 9 is smaller than the width direction dimension of the front surface 8a of the back support portion 8, and the upper portion and both side portions of the front surface 8a protrude from the buffer plate 9, respectively. It is in a state. Here, the width direction of the buffer plate 9 is the same as the width direction of the glass plates G stacked on the pallet 2 in the vertical posture, and is the longitudinal direction of the side of the glass plate G extending in the horizontal direction. At this time, the area of the laminate 3 is smaller than the area of the front surface 9a of the buffer plate 9, and when the laminate 3 is placed on the pallet 2 as shown in FIG. It is in a state of protruding from the laminate 3. As shown in FIG. 4, the upper portion of the buffer plate 9 protrudes from the glass plate G, while the slip sheet I protrudes from the upper portion of the buffer plate 9. Therefore, at least the entire surface of the glass plate G is supported by the front surface 9a of the buffer plate 9 via the slip sheet I.
　また、ガラス板Ｇと合紙Ｉとのサイズを比較した場合、ガラス板Ｇの面積は合紙Ｉの面積より小さく、ガラス板Ｇと合紙Ｉとを縦姿勢で交互に積層した状態では、図４に拡大して示すように、ガラス板Ｇの上辺側で合紙Ｉがガラス板Ｇから食み出した状態となっている。この場合、緩衝板９の上端に隣接して板状部材１０が配設され、板状部材１０の前面１０ａが、合紙Ｉのうちガラス板Ｇの上辺から食み出した部分と対向している。また、図示は省略するが、本実施形態では、ガラス板Ｇの両側辺側で合紙Ｉがガラス板Ｇから食み出すと共に、緩衝板９の前面９ａがその両側辺側で合紙Ｉから食み出した状態となっている。以上より、本実施形態では、緩衝板９の前面９ａ及び板状部材１０の前面１０ａが本発明に係る支持面に相当する。また、緩衝板９の前面９ａのうちガラス板Ｇの全面と対向する領域が本発明に係る第一対向領域１１ａに相当し、前面９ａのうちガラス板Ｇの側辺から食み出した合紙Ｉと対向する領域と、板状部材１０の前面１０ａのうちガラス板Ｇの上辺から食み出した合紙Ｉと対向する領域とが本発明に係る第二対向領域１１ｂに相当する。 When the sizes of the glass sheet G and the slip sheet I are compared, the area of the glass sheet G is smaller than the area of the slip sheet I, and in a state where the glass sheet G and the slip sheet I are alternately stacked in the vertical posture, As shown in an enlarged manner in FIG. 4, the slip sheet I protrudes from the glass plate G on the upper side of the glass plate G. In this case, the plate member 10 is disposed adjacent to the upper end of the buffer plate 9, and the front surface 10a of the plate member 10 faces the portion of the slip sheet I protruding from the upper side of the glass plate G. I have. Although not shown, in this embodiment, the slip sheet I protrudes from the glass sheet G on both sides of the glass sheet G, and the front surface 9a of the buffer plate 9 is separated from the slip sheet I on both sides. It is in a state of extruding. As described above, in the present embodiment, the front surface 9a of the buffer plate 9 and the front surface 10a of the plate member 10 correspond to the support surface according to the present invention. Further, a region facing the entire surface of the glass plate G in the front surface 9a of the buffer plate 9 corresponds to the first facing region 11a according to the present invention, and the slip sheet protruding from the side of the glass plate G in the front surface 9a. The region facing I and the region facing the slip sheet I protruding from the upper side of the glass plate G in the front surface 10a of the plate-shaped member 10 correspond to the second facing region 11b according to the present invention.
　第二対向領域１１ｂには、押込み可能な変化面１２が設けられている（図４を参照）。本実施形態では、第二対向領域１１ｂのうちガラス板Ｇの上辺側でガラス板Ｇから食み出した合紙Ｉと対向する部分に矩形状の変化面１２が設けられている。この場合、変化面１２は、可動する板状部材１０の前面１０ａで形成されており、板状部材１０は、例えば付勢部材１３を介して背面支持部８と連結されることにより、所定の向きの押込みに抗する向きに付勢されている。本実施形態では、板状部材１０の上端が付勢部材１３を介して背面支持部８に連結されており、これにより、板状部材１０がその上端で水平方向に伸びる軸まわりに傾動可能とされている。さらに言えば、合紙Ｉの押込みに応じて、第一対向領域１１ａに対する変化面１２の傾斜角θ３が変化する。なお、付勢部材１３としては、例えば圧縮コイル、ねじりコイルばね、薄板ばねなどのスプリング、ゴム板など、凡そ合紙Ｉの押込みに抗する向きに付勢力を発生させ得る限りにおいて任意の材質、構造を有する要素が採用可能である。なお、本実施形態では、付勢部材１３によって板状部材１０と背面支持部８とを傾動可能に連結すると共に板状部材１０を付勢するが、蝶番等の連結部材によって板状部材１０と背面支持部８とを傾動可能に連結した状態で圧縮コイル等の付勢部材によって板状部材１０を付勢してもよい。 変 化 The second opposing region 11b is provided with a changeable surface 12 that can be pushed (see FIG. 4). In the present embodiment, a rectangular changing surface 12 is provided in a portion of the second opposing region 11b on the upper side of the glass plate G facing the interleaving paper I protruding from the glass plate G. In this case, the change surface 12 is formed by the front surface 10 a of the movable plate member 10, and the plate member 10 is connected to the back support portion 8 via the urging member 13, for example, to thereby provide a predetermined surface. It is urged in a direction against pushing in the direction. In the present embodiment, the upper end of the plate-shaped member 10 is connected to the back support portion 8 via the biasing member 13, so that the plate-shaped member 10 can be tilted around an axis extending in the horizontal direction at the upper end. Have been. More specifically, the inclination angle θ3 of the changing surface 12 with respect to the first facing region 11a changes according to the insertion of the slip sheet I. The biasing member 13 may be made of any material, for example, a compression coil, a torsion coil spring, a spring such as a thin plate spring, a rubber plate, or any other material as long as the biasing force can be generated in a direction against the pushing of the slip sheet I. Elements having a structure can be employed. In the present embodiment, the plate member 10 and the back support 8 are tiltably connected by the biasing member 13 and the plate member 10 is biased, but the plate member 10 is biased by a connecting member such as a hinge. The plate-shaped member 10 may be urged by an urging member such as a compression coil in a state where the plate-shaped member 10 is tiltably connected to the back support portion 8.
　また、この板状部材１０の前面１０ａ（変化面１２）は、何らの負荷（押込み力等）が作用していない状態（図４に示す状態）では、第一対向領域１１ａから遠ざかるにつれてガラス板Ｇの積層方向Ｘで第一対向領域１１ａよりも低い側（図４でいえば左下側）に後退するよう、前面１０ａが緩衝板９の前面９ａに対して傾いている。また、第一対向領域１１ａに対する前面１０ａの傾斜角θ３は、後述する保持手段としての吸着パッド１４の押込み方向Ｙ（図６Ａを参照）に対して適宜の範囲に設定され、例えば前面１０ａの法線方向が押込み方向Ｙと略一致するよう、所定の大きさに設定される。 Further, the front surface 10a (change surface 12) of the plate-shaped member 10 has a glass plate as it moves away from the first opposing region 11a in a state where no load (such as a pushing force) is applied (a state shown in FIG. 4). The front surface 10a is inclined with respect to the front surface 9a of the buffer plate 9 so as to retreat to a lower side (lower left side in FIG. 4) than the first facing region 11a in the stacking direction X of G. The inclination angle θ3 of the front surface 10a with respect to the first facing region 11a is set to an appropriate range with respect to a pressing direction Y (see FIG. 6A) of the suction pad 14 as a holding unit described later. The size is set to a predetermined size such that the line direction substantially matches the pushing direction Y.
　また、前面１０ａ（変化面１２）の幅方向寸法は、例えばガラス板Ｇの上辺側で食み出した合紙Ｉとその幅方向全域で対向するように設定されている（図１及び図３を参照）。また、前面１０ａの幅方向に直交する向き（図３でいえば上下方向）の寸法は、例えばガラス板Ｇの上辺側で食み出した合紙Ｉとその上下方向全域で対向するように設定されている。 The width dimension of the front surface 10a (change surface 12) is set so as to oppose, for example, the interleaving paper I protruding on the upper side of the glass plate G in the entire width direction thereof (FIGS. 1 and 3). See). The dimension of the front surface 10a in the direction orthogonal to the width direction (vertical direction in FIG. 3) is set, for example, so as to face the interleaving paper I protruding on the upper side of the glass plate G in the entire vertical region. Have been.
　板状部材１０の材質は任意であり、例えばステンレスなどの金属が採用可能である。この場合、板状部材１０の前面１０ａで構成される変化面１２も同じ金属で形成される。あるいは、板状部材１０を金属以外の材料で形成し、その表面に金属膜などを形成することで、変化面１２を金属製としてもよい。もちろん、板状部材１０と変化面１２とを異なる金属で形成してもよい。 材質 The material of the plate member 10 is arbitrary, and for example, a metal such as stainless steel can be adopted. In this case, the changing surface 12 formed by the front surface 10a of the plate-shaped member 10 is also formed of the same metal. Alternatively, the change surface 12 may be made of metal by forming the plate-like member 10 with a material other than metal and forming a metal film or the like on the surface thereof. Of course, the plate member 10 and the change surface 12 may be formed of different metals.
　上記構成の積層体パレット一体品１は、例えば所定の形態で梱包され、出荷される。図５は、図１に係る積層体パレット一体品１の積層体３を梱包してなる梱包体１５の一例を示している。図５に示すように、この梱包体１５は、上述した積層体パレット一体品１と、積層体３を束縛するベルト１６と、ベルト１６と積層体３の前面との間に配設される押さえ部材１７と、ベルト１６の積層体３の側部との間に配設されるサイドストッパ１８とを備える。ベルト１６の長手方向両端は、例えば図１に示すように、積層体３がパレット２上の所定位置に縦姿勢で搭載された状態で、背面支持部８に設けられたフック１９に掛けられ、二重にした状態で、押さえ部材１７の前面上で図示しないラチェット等により締め付けた状態で固定される。これにより、積層体３が前後左右方向への移動を規制された状態で、パレット２に固定される。なお、この際、図５に示すように、積層体３の最も前面側にフレーム板２０を載置し、このフレーム板２０と積層体３、及び押さえ部材１７をベルト１６で背面支持部８側に押圧してもよい。 積 層 The laminated pallet integrated product 1 having the above configuration is packed and shipped in a predetermined form, for example. FIG. 5 shows an example of a package 15 formed by packing the laminate 3 of the laminated pallet integrated product 1 according to FIG. As shown in FIG. 5, the package 15 is composed of the above-described laminated pallet integrated product 1, a belt 16 for binding the laminated body 3, and a presser disposed between the belt 16 and the front surface of the laminated body 3. A side stopper 18 is provided between the member 17 and the side of the stacked body 3 of the belt 16. At both ends in the longitudinal direction of the belt 16, for example, as shown in FIG. 1, in a state where the laminated body 3 is mounted at a predetermined position on the pallet 2 in a vertical posture, the hooks 19 provided on the back support portion 8 In the doubled state, it is fixed on the front surface of the holding member 17 by being fastened by a ratchet or the like (not shown). Thereby, the laminated body 3 is fixed to the pallet 2 in a state where the movement in the front, rear, left and right directions is restricted. At this time, as shown in FIG. 5, a frame plate 20 is placed on the foremost side of the laminate 3, and the frame plate 20, the laminate 3, and the pressing member 17 are connected to the back support portion 8 by the belt 16. May be pressed.
　出荷先では、梱包体１５の開梱作業が行われ、パレット２上の積層体３からガラス板Ｇの取出しが行われる。以下、ガラス板Ｇの取出し時における合紙Ｉの排出手順を、本発明の作用効果と共に、主に図６Ａ～図８に基づき説明する。 (4) At the shipping destination, the unpacking operation of the package 15 is performed, and the glass plate G is taken out from the laminate 3 on the pallet 2. Hereinafter, the procedure for discharging the slip sheet I when the glass sheet G is taken out, together with the operation and effect of the present invention, will be described mainly with reference to FIGS. 6A to 8.
　開梱作業は、例えばアンパッカー装置と呼ばれる開梱装置により行われる。ここで、アンパッカー装置は、ガラス板Ｇを真空吸着するための第一の吸着パッド（図示は省略）と、ガラス板Ｇの間に介在する合紙Ｉを真空吸着するための第二の吸着パッド（図６Ａに示す吸着パッド１４）とを備えており、第一の吸着パッドで積層体３上のガラス板Ｇを吸着保持し、パレット２上からガラス板Ｇを取出すと共に、第二の吸着パッド（吸着パッド１４）で合紙Ｉを吸着保持し、パレット２外に排出する。 梱 The unpacking operation is performed by, for example, an unpacking device called an unpacker device. Here, the unpacker device includes a first suction pad (not shown) for vacuum-sucking the glass plate G and a second suction pad for vacuum-sucking the slip sheet I interposed between the glass plates G. The first suction pad holds the glass plate G on the laminate 3 by suction, the glass plate G is taken out from the pallet 2 and the second suction The interleaf paper I is sucked and held by the pad (suction pad 14), and is discharged out of the pallet 2.
　ここで、合紙Ｉの排出作業は、合紙Ｉのうちガラス板Ｇから食み出した部分を吸着パッド１４で吸着保持する動作と、吸着保持した合紙Ｉをパレット２上から退避させる動作とに大別される。具体的には、合紙Ｉを吸着保持する動作については、例えば図６Ａに示すように、吸着パッド１４を押込んだときの合紙Ｉの背面支持部８側への倒れ込みを想定して、ガラス板Ｇの積層方向Ｘに対して垂直な向きよりも斜め上方から吸着パッドを接近させる動作が採用される。このように所定の方向Ｙから、積層体３の最も前面側に位置する合紙Ｉのうちガラス板Ｇから食み出した部分に向けて吸着パッド１４を押込む。そして、吸着パッド１４を合紙Ｉと密着させた状態で合紙Ｉを真空吸着し、合紙Ｉの上縁部を吸着パッド１４で保持する。 Here, the operation of discharging the slip sheet I includes an operation of sucking and holding the portion of the slip sheet I protruding from the glass plate G with the suction pad 14 and an operation of retracting the sucked and held slip sheet I from the pallet 2. They are roughly divided into Specifically, as for the operation of sucking and holding the slip sheet I, for example, as shown in FIG. 6A, assuming that the slip sheet I falls down to the back support portion 8 side when the suction pad 14 is pushed in, An operation of approaching the suction pad from obliquely above the direction perpendicular to the laminating direction X of the glass plate G is employed. As described above, the suction pad 14 is pressed from the predetermined direction Y toward the portion of the slip sheet I located on the frontmost side of the laminate 3 protruding from the glass plate G. Then, with the suction pad 14 in close contact with the slip sheet I, the slip sheet I is vacuum-sucked, and the upper edge of the slip sheet I is held by the suction pad 14.
　然る後、吸着パッド１４を合紙Ｉに押込んだ状態を維持しながらガラス板Ｇの平面方向に沿って吸着パッド１４を移動させることで、合紙Ｉを積層体３上から退避させる。本実施形態では、図６Ｂに示すように、吸着パッド１４を例えば水平方向に伸びる所定の軸まわりに回動させることで、吸着パッド１４を合紙Ｉに押込んだ状態を維持しながら、吸着パッド１４を上方に移動させる。これにより、合紙Ｉの背面側に位置するガラス板Ｇとの密着状態を解消して、合紙Ｉのみを上方に排出する。以上の動作を、第一の吸着パッド（図示は省略）によるガラス板Ｇの取出し動作と交互に繰り返すことで、ガラス板Ｇと合紙Ｉとが交互にパレット２上から排出される。 Thereafter, by moving the suction pad 14 along the plane direction of the glass plate G while maintaining the state where the suction pad 14 is pressed into the slip sheet I, the slip sheet I is retracted from the laminate 3. In the present embodiment, as shown in FIG. 6B, the suction pad 14 is rotated, for example, around a predetermined axis extending in the horizontal direction, so that the suction pad 14 is pressed into the slip sheet I, and the suction pad 14 is held. The pad 14 is moved upward. Thus, the state of close contact with the glass plate G located on the back side of the slip sheet I is eliminated, and only the slip sheet I is discharged upward. The above operation is alternately repeated with the operation of taking out the glass plate G by the first suction pad (not shown), so that the glass plate G and the slip sheet I are discharged from the pallet 2 alternately.
　ところで、上述のように吸着パッド１４を操作して合紙Ｉをパレット２上から排出する場合、合紙Ｉ及びガラス板Ｇが残り少なくなると、吸着パッド１４と合紙Ｉとの接触状態が変化するため、従来構成のパレットでは、安定して合紙Ｉを吸着保持することが難しくなる。すなわち、吸着パッド１４が、常に一定の角度（押込み方向Ｙ）で合紙Ｉに向けて押込まれる場合、図８に示すように、第二対向領域１１ｂに変化面１２が設けられていない従来構成のパレット１０２では、合紙Ｉが残り少なくなった状態で吸着パッド１４に押込まれた際、合紙Ｉの背面側への倒れ込みが第二対向領域１１ｂ（緩衝板９の前面９ａ）により規制される。その結果、合紙Ｉの残り枚数が十分であったとき（図６Ａ）よりも、吸着パッド１４を押込んだ際の合紙Ｉの倒れ込み角度が小さくなる（図８を参照）。これでは、吸着パッド１４の押込み角度と、合紙Ｉの倒れ込み角度とにずれが生じ、吸着パッド１４が合紙Ｉに対して部分的に接触することになるため、合紙Ｉを安定して吸着保持することが難しい。 By the way, when the interleaf I is discharged from the pallet 2 by operating the suction pad 14 as described above, the contact state between the suction pad 14 and the interleaf I changes when the interleaf I and the glass plate G are reduced. Therefore, it is difficult for the pallet having the conventional configuration to stably hold the slip sheet I by suction. That is, when the suction pad 14 is always pushed toward the slip sheet I at a constant angle (the pushing direction Y), as shown in FIG. In the pallet 102 having the configuration, when the slip sheet I is pushed into the suction pad 14 in a state where the remaining slip sheet is low, the falling of the slip sheet I to the back side is restricted by the second facing region 11b (the front face 9a of the buffer plate 9). You. As a result, the falling angle of the slip sheet I when the suction pad 14 is pressed is smaller than when the remaining number of slip sheets I is sufficient (see FIG. 6A) (see FIG. 8). In this case, a difference occurs between the pressing angle of the suction pad 14 and the falling angle of the slip sheet I, and the suction pad 14 comes into partial contact with the slip sheet I. Difficult to hold by suction.
　これに対して、本発明に係る積層体パレット一体品１では、図４等に示すように、積層体３の背面３ｂを支持する支持面（ここでは緩衝板９の前面９ａと板状部材１０の前面１０ａ）のうち、ガラス板Ｇから食み出した合紙Ｉと対向する第二対向領域１１ｂに、押込みが可能な変化面１２を設けた。上記構成によれば、吸着パッド１４によって合紙Ｉと共に変化面１２が押し込まれることから、合紙Ｉを必要十分な量だけ倒れ込ませることができる（図７Ｂを参照）。以上より、本発明に係る積層体パレット一体品１によれば、合紙Ｉの残り枚数に関係なく、合紙Ｉと吸着パッド１４との接触状態を安定させて、確実に合紙Ｉを吸着保持することが可能となる。 On the other hand, in the laminated pallet integrated product 1 according to the present invention, as shown in FIG. 4 and the like, the support surface (here, the front surface 9a of the buffer plate 9 and the plate-like member 10) supporting the back surface 3b of the laminated body 3 is provided. In the front surface 10a), a changeable surface 12 capable of being pushed is provided in a second facing region 11b facing the slip sheet I protruding from the glass plate G. According to the above configuration, since the change surface 12 is pushed together with the slip sheet I by the suction pad 14, the slip sheet I can be fallen by a necessary and sufficient amount (see FIG. 7B). As described above, according to the laminated pallet integrated product 1 of the present invention, the contact state between the slip sheet I and the suction pad 14 is stabilized regardless of the remaining number of slip sheets I, and the slip sheet I is reliably sucked. It is possible to hold.
　また、本発明に係る積層体パレット一体品１では、合紙Ｉに作用する背面側への押込み力を変化面１２で吸収しながら、合紙Ｉを支持することができる。よって、吸着パッド１４で合紙Ｉを背面側に押込みながら、合紙Ｉをガラス板Ｇの表面に沿った向き（積層方向Ｘに直交する向き）に移動させる際に、合紙Ｉに作用する摩擦抵抗を軽減することができる。以上より、本発明に係る積層体パレット一体品１によれば、吸着パッド１４から合紙Ｉが外れる事態を回避して、合紙Ｉのみを確実にパレット２上から排出することが可能となる。 In addition, in the laminated pallet integrated product 1 according to the present invention, the interleaf I can be supported while the pushing force to the back side acting on the interleaf I is absorbed by the changing surface 12. Therefore, when the interleaf I is moved in a direction along the surface of the glass plate G (a direction orthogonal to the laminating direction X) while the interleaf I is pushed to the rear side by the suction pad 14, the interleaf I acts on the interleaf I. Friction resistance can be reduced. As described above, according to the laminated pallet integrated product 1 of the present invention, it is possible to prevent the slip sheet I from coming off the suction pad 14 and to reliably discharge only the slip sheet I from the pallet 2. .
　また、本実施形態では、変化面１２を可動する板状部材１０の前面１０ａで形成し、この板状部材１０をガラス板Ｇの支持面となる第一対向領域１１ａと平行な軸まわりに傾動可能に構成した。このように、変化面１２を板状部材１０の前面１０ａで形成すれば、押込んだ際の合紙Ｉの形状が、板状部材１０の形状に倣った状態で安定する。よって、合紙Ｉを吸着パッド１４により安定して吸着保持することが可能となる。また、上記構成によれば、吸着パッド１４の押込みに応じて、適切な姿勢（倒れ込み角度）まで合紙Ｉを倒れ込ませることができる。これにより、吸着パッド１４と合紙Ｉとの接触状態を安定させることができるので、摩擦抵抗を軽減しつつも、合紙Ｉをより確実に吸着保持した状態で排出することが可能となる。 Further, in the present embodiment, the changing surface 12 is formed by the front surface 10a of the movable plate member 10, and the plate member 10 is tilted about an axis parallel to the first facing region 11a serving as the support surface of the glass plate G. Configured to be possible. As described above, if the changing surface 12 is formed by the front surface 10a of the plate member 10, the shape of the slip sheet I when pushed is stabilized in a state following the shape of the plate member 10. Therefore, the slip sheet I can be stably held by the suction pad 14. Further, according to the above configuration, the slip sheet I can be fallen down to an appropriate posture (falling angle) according to the depression of the suction pad 14. This makes it possible to stabilize the contact state between the suction pad 14 and the interleaf I, so that it is possible to discharge the interleaf I in a more reliably sucked and held state while reducing frictional resistance.
　また、本実施形態では、板状部材１０を、押込みに抗する向きに付勢されるようにしたので、合紙Ｉの背面側への押込みが解消されるのに伴い、板状部材１０を自動的に押込み前の位置又は姿勢に復帰（例えば図７Ｂに示す姿勢から図４に示す姿勢に復帰）させることができる。従って、合紙Ｉの残り枚数によって合紙Ｉの押込み態様が変化する場合であっても、合紙Ｉに作用する摩擦抵抗を安定的に軽減することが可能となる。また、板状部材１０を付勢するだけであれば、非常に簡素な構成で済むため、パレットの改良コストも抑えられる。 Further, in the present embodiment, since the plate-like member 10 is urged in a direction against the pushing, the pushing of the sheet-like member 10 to the back side of the interleaving paper I is canceled, It is possible to automatically return to the position or posture before pushing (for example, return from the posture shown in FIG. 7B to the posture shown in FIG. 4). Therefore, even when the pressing state of the interleaf I changes depending on the remaining number of the interleaf I, the frictional resistance acting on the interleaf I can be stably reduced. Further, if only the plate-like member 10 is urged, a very simple configuration is sufficient, and the cost for improving the pallet can be suppressed.
　また、本実施形態では、板状部材１０の前面１０ａ（変化面１２）は、何らの負荷（押込み力等）が作用していない状態（図４に示す状態）では、第一対向領域１１ａから遠ざかるにつれてガラス板Ｇの積層方向Ｘで第一対向領域１１ａよりも低い側（図４でいえば左下側）に後退するよう、前面１０ａが緩衝板９の前面９ａに対して傾いている。これにより、吸着パッド１４を押込んだ際に合紙Ｉが倒れ込みやすくなるので、合紙Ｉの残り枚数に関係なく、合紙Ｉと吸着パッド１４との接触状態をさらに安定させて、より確実に合紙Ｉを吸着保持することが可能となる。このように板状部材１０の前面１０ａ（変化面１２）を緩衝板９の前面９ａに対して傾ける場合、板状部材１０の前面１０ａ（変化面１２）の傾斜角θ３は、前面１０ａの法線方向が押込み方向Ｙと略一致するように設定されることが好ましい。この場合、板状部材１０の前面１０ａの傾きを確保できる程度に、緩衝板９を厚くすることが好ましい。 Further, in the present embodiment, the front surface 10a (change surface 12) of the plate-shaped member 10 moves from the first opposing region 11a in a state where no load (such as a pushing force) is applied (a state shown in FIG. 4). The front surface 10a is inclined with respect to the front surface 9a of the buffer plate 9 so that the front surface 10a retreats to a lower side (lower left side in FIG. 4) than the first facing region 11a in the stacking direction X of the glass sheets G as the distance increases. This makes it easy for the slip sheet I to fall down when the suction pad 14 is pushed in, so that the contact state between the slip sheet I and the suction pad 14 is further stabilized, regardless of the number of remaining sheets of the slip sheet I, and more reliable. In this case, the slip sheet I can be held by suction. When the front surface 10a (change surface 12) of the plate member 10 is inclined with respect to the front surface 9a of the buffer plate 9 as described above, the inclination angle θ3 of the front surface 10a (change surface 12) of the plate member 10 is the modulus of the front surface 10a. It is preferable that the line direction is set so as to substantially coincide with the pushing direction Y. In this case, it is preferable to make the buffer plate 9 thick enough to ensure the inclination of the front surface 10a of the plate member 10.
　以上、本発明に係る積層体パレット一体品、及びパレットの第一実施形態を説明したが、この積層体パレット一体品、及びパレットは、当然に本発明の範囲内において任意の形態を採ることができる。 As described above, the laminated pallet integrated product and the first embodiment of the pallet according to the present invention have been described. However, the laminated pallet integrated product and the pallet may take any form within the scope of the present invention. it can.
＜本発明の第二実施形態＞
　例えば変化面１２について、第一実施形態では緩衝板９の上端に隣接して可動する板状部材１０を設け、この板状部材１０の前面１０ａで変化面１２を形成した場合を説明したが、もちろんこれ以外の形態をとることも可能である。図９Ａ及び図９Ｂは、本発明の第二実施形態に係る積層体パレット一体品２１の要部拡大側面図を示している。図９Ａに示すように、本実施形態に係る積層体パレット一体品２１では、背面支持部８の前面８ａのうち合紙Ｉと対向する第二対向領域１１ｂに、前面８ａに対して窪んだ状態の窪み部２２が設けられており、この窪み部２２上に板状部材１０が取付けられている。この場合も、可動する板状部材１０の前面１０ａで変化面２３が形成されており、板状部材１０の上端が付勢部材１３を介して窪み部２２の内側面に連結されることで、板状部材１０を窪み部２２内で傾動可能としている。上記構成によれば、例えば背面支持部８の前面８ａ上に傾動可能な板状部材１０を設ける場合（図４を参照）よりも、板状部材１０の傾動を許容するスペースを板状部材１０の背面側に大きく設けることができる（図９Ｂを参照）。これにより、吸着パッド１４の押込み角度や押込み量の許容範囲を広げることができるので、合紙Ｉを安定して吸着保持しつつも、押込み力を吸収して摩擦抵抗を軽減することにより確実に合紙Ｉのみをパレット２上から排出することが可能となる。なお、図９Ａでは、板状部材１０の前面１０ａ下端を緩衝板９の前面９ａ（第一対向領域１１ａ）よりも若干低く設定しているが、逆に高く設定してもかまわない。あるいは、板状部材１０の前面１０ａ下端と緩衝板９の前面９ａとを同じ高さとしてもよい。 <Second embodiment of the present invention>
For example, in the first embodiment, the case where the movable plate 12 is provided adjacent to the upper end of the buffer plate 9 and the movable surface 12 is formed on the front surface 10a of the plate 10 has been described. Of course, other forms are also possible. 9A and 9B are enlarged side views of a main part of the laminated pallet integrated product 21 according to the second embodiment of the present invention. As shown in FIG. 9A, in the laminated body pallet integrated product 21 according to the present embodiment, a state in which the front face 8 a of the back support portion 8 is recessed in the second facing area 11 b facing the slip sheet I with respect to the front face 8 a. Are provided, and the plate-shaped member 10 is mounted on the recess 22. Also in this case, the changing surface 23 is formed on the front surface 10 a of the movable plate member 10, and the upper end of the plate member 10 is connected to the inner surface of the recess 22 via the biasing member 13, The plate member 10 can be tilted within the recess 22. According to the above configuration, for example, a space allowing the tilting of the plate-shaped member 10 is made larger than that of the case where the tiltable plate-shaped member 10 is provided on the front surface 8a of the back support portion 8 (see FIG. 4). (See FIG. 9B). As a result, the allowable range of the pressing angle and the pressing amount of the suction pad 14 can be widened. Therefore, while stably holding the interleaf sheet I, the pressing force is absorbed to reduce the frictional resistance. Only the slip sheet I can be discharged from the pallet 2. In FIG. 9A, the lower end of the front surface 10a of the plate member 10 is set slightly lower than the front surface 9a (first opposing region 11a) of the buffer plate 9, but may be set higher. Alternatively, the lower end of the front surface 10a of the plate member 10 and the front surface 9a of the buffer plate 9 may be at the same height.
　本実施形態では、板状部材１０の前面１０ａ（変化面２３）は、何らの負荷（押込み力等）が作用していない状態（図９Ａに示す状態）では、緩衝板９の前面９ａと平行である。また、本実施形態では、板状部材１０の上端を支点として傾動可能とされている。このため、合紙Ｉ及びガラス板Ｇが残り少なくなると、吸着パッド１４を押込んだ際に吸着パッド１４の押込み方向Ｙ（吸着面の法線方向）と、前面１０ａの法線方向とにずれが生じるが、吸着パッド１４を水平方向に伸びる所定の軸まわりに回動させる過程で吸着パッド１４の角度が変化して吸着パッド１４の吸着面の法線方向と前面１０ａの法線方向が一致する。これにより、合紙Ｉの残り枚数に関係なく、確実に合紙Ｉを吸着保持することが可能となる。 In the present embodiment, the front surface 10a (change surface 23) of the plate member 10 is parallel to the front surface 9a of the buffer plate 9 in a state where no load (such as a pushing force) is applied (a state shown in FIG. 9A). It is. Further, in the present embodiment, the plate-like member 10 can be tilted about the upper end thereof as a fulcrum. For this reason, when the interleaf paper I and the glass plate G are reduced, when the suction pad 14 is pressed, the pressing direction Y of the suction pad 14 (the normal direction of the suction surface) and the normal direction of the front surface 10a shift. However, in the process of rotating the suction pad 14 about a predetermined axis extending in the horizontal direction, the angle of the suction pad 14 changes, and the normal direction of the suction surface of the suction pad 14 matches the normal direction of the front surface 10a. . This makes it possible to reliably hold and hold the slip sheet I regardless of the remaining number of slip sheets I.
　本実施形態のように背面支持部８に窪み部２２を設ける場合、背面支持部８を内部が空洞の箱状とすることが好ましい。これにより、梁を設けなくても背面支持部８の剛性を確保できるので、窪み部２２を容易に設けることが可能となる。 In the case where the concave portion 22 is provided in the back support portion 8 as in the present embodiment, it is preferable that the back support portion 8 is formed in a box shape having a hollow inside. Thereby, the rigidity of the back support portion 8 can be secured without providing a beam, so that the recess portion 22 can be easily provided.
＜本発明の第三実施形態＞
　また、上述した本発明の第一及び第二実施形態では、板状部材１０の上端を支点として板状部材１０が傾動する形態を採用した場合を例示したが、もちろんこれ以外の形態を採用することも可能である。図１０Ａ及び図１０Ｂは、本発明の第三実施形態に係る積層体パレット一体品３１の要部拡大側面図を示している。図１０Ａに示すように、本実施形態に係る板状部材１０は、第二実施形態と同様、背面支持部８の前面８ａに設けた窪み部２２上に取付けられている。その一方で、板状部材１０はその下端で付勢部材１３を介して窪み部２２の内側面に連結されている。これにより板状部材１０は、その下端を支点として傾動可能とされるので、板状部材１０の前面１０ａで構成される変化面３２もまたその下端を支点として傾動可能とされる（図１０Ｂを参照）。この構成によっても、板状部材１０の傾動を許容するスペースを板状部材１０の背面側に大きく設けることができる。これにより、吸着パッド１４の押込み角度や押込み量の許容範囲を広げることができるので、合紙Ｉを安定して吸着保持しつつも、押込み力を吸収して摩擦抵抗を軽減することにより確実に合紙Ｉのみをパレット２上から排出することが可能となる。 <Third embodiment of the present invention>
Further, in the above-described first and second embodiments of the present invention, the case where the plate-shaped member 10 is tilted with the upper end of the plate-shaped member 10 as a fulcrum is exemplified. However, other forms are naturally used. It is also possible. FIG. 10A and FIG. 10B are enlarged side views of a main part of the laminated pallet integrated product 31 according to the third embodiment of the present invention. As shown in FIG. 10A, the plate-shaped member 10 according to the present embodiment is mounted on a recess 22 provided on the front surface 8a of the back support 8 as in the second embodiment. On the other hand, the plate-shaped member 10 is connected at its lower end to the inner surface of the recess 22 via the biasing member 13. Thus, the plate-shaped member 10 can be tilted with its lower end as a fulcrum, so that the changing surface 32 formed by the front surface 10a of the plate-shaped member 10 can also be tilted with its lower end as a fulcrum (see FIG. 10B). reference). Also according to this configuration, a large space for allowing the plate member 10 to tilt can be provided on the rear side of the plate member 10. As a result, the allowable range of the pressing angle and the pressing amount of the suction pad 14 can be widened. Therefore, while stably holding the interleaf sheet I, the pressing force is absorbed to reduce the frictional resistance. Only the slip sheet I can be discharged from the pallet 2.
　本実施形態では、板状部材１０の前面１０ａ（変化面３２）は、何らの負荷（押込み力等）が作用していない状態（図１０Ａに示す状態）では、緩衝板９の前面９ａと平行である。また、本実施形態の板状部材１０は、板状部材１０の下端（第一対向領域１１ａに近い側の端部）を支点として傾動可能とされている。このため、合紙Ｉ及びガラス板Ｇが残り少なくなると、吸着パッド１４によって合紙Ｉと共に変化面３２を押し込む過程、あるいは、吸着パッド１４を水平方向に伸びる所定の軸まわりに回動させる過程で前面１０ａが倒れ込み、吸着パッド１４の吸着面の法線方向と前面１０ａの法線方向が一致する。これにより、合紙Ｉの残り枚数に関係なく、確実に合紙Ｉを吸着保持することが可能となる。 In this embodiment, the front surface 10a (change surface 32) of the plate member 10 is parallel to the front surface 9a of the buffer plate 9 in a state where no load (such as a pushing force) is applied (a state shown in FIG. 10A). It is. Further, the plate-shaped member 10 of the present embodiment can be tilted with the lower end of the plate-shaped member 10 (the end closer to the first facing region 11a) as a fulcrum. For this reason, when the interleaf I and the glass plate G are running low, the suction pad 14 pushes the change surface 32 together with the interleaf I, or the suction pad 14 rotates around a predetermined axis extending in the horizontal direction. The normal direction of the suction surface of the suction pad 14 matches the normal direction of the front surface 10a. This makes it possible to reliably hold the slip sheet I by suction regardless of the number of remaining slip sheets I.
＜本発明の第四実施形態＞
　また、以上の実施形態では、板状部材１０を傾動可能として、この板状部材１０の前面１０ａで構成される変化面１２，２３，３２を移動（傾動）させる場合を例示したが、もちろんこれ以外の形態をとることも可能である。図１１Ａ及び図１１Ｂは、本発明の第四実施形態に係る積層体パレット一体品４１の要部拡大側面図を示している。図１１Ａに示すように、本実施形態に係る積層体パレット一体品４１においては、緩衝板９の上端に隣接して弾性板４２が配設され、この弾性板４２の前面４３で変化面４４が形成されている。この場合、緩衝板９の前面９ａ及び弾性板４２の前面４３が本発明に係る支持面に相当する。弾性板４２は、例えば緩衝板９よりも変形し易い材料、具体的には吸着パッド１４の押込みに応じて前面４３が変形可能な弾性体（ゴム、スポンジなど）で形成される。上記構成によれば、合紙Ｉに対する吸着時の押込みに対してより柔軟に対応することができる。従って、吸着パッド１４による押込み態様が安定しない場合であっても、確実に摩擦抵抗を軽減することが可能となる。 <Fourth embodiment of the present invention>
Further, in the above-described embodiment, the case where the plate-shaped member 10 can be tilted and the changing surfaces 12, 23, 32 formed by the front surface 10a of the plate-shaped member 10 are moved (tilted) is exemplified. Other forms are also possible. 11A and 11B are enlarged side views of a main part of a laminated pallet integrated product 41 according to a fourth embodiment of the present invention. As shown in FIG. 11A, in the laminated pallet integrated product 41 according to the present embodiment, an elastic plate 42 is disposed adjacent to the upper end of the buffer plate 9, and a change surface 44 is formed on the front surface 43 of the elastic plate 42. Is formed. In this case, the front surface 9a of the buffer plate 9 and the front surface 43 of the elastic plate 42 correspond to the support surface according to the present invention. The elastic plate 42 is made of, for example, a material that is more easily deformed than the buffer plate 9, specifically, an elastic body (rubber, sponge, or the like) whose front surface 43 can be deformed in response to the pressing of the suction pad 14. According to the above configuration, it is possible to more flexibly cope with the pressing of the interleaving paper I during suction. Therefore, even when the pressing mode by the suction pad 14 is not stable, the frictional resistance can be reliably reduced.
＜本発明の第五実施形態＞
　図１２は、本発明の第五実施形態に係る積層体パレット一体品５１の斜視図を示している。図１２において、積層体３は二点鎖線で描いている。本実施形態に係る積層体パレット一体品５１は、全体として矩形状の変化面５２ａ～５２ｃが、その長手方向に分割されている点において、上記実施形態に係る積層体パレット一体品１，２１，３１，４１と相違している。具体的には、水平方向に分割され、かつ別個独立に可動（本実施形態では傾動）する複数の板状部材５３ａ～５３ｃの前面５３ａ１～５３ｃ１でそれぞれ変化面５２ａ～５２ｃが形成されている。上記構成によれば、吸着パッド１４（図６Ａ等を参照）による合紙Ｉの押込み量が、水平方向でばらつく場合であっても、板状部材５３ａ～５３ｃの傾動度合いを板状部材５３ａ～５３ｃごとに異ならせて、押込み量の水平方向でのばらつきを吸収することができる。よって、本構成によれば、水平方向での押込み量のばらつきを吸収しつつ、合紙Ｉに作用する摩擦抵抗をその水平方向全域にわたって効果的に軽減することが可能となる。なお、図１２では、変化面を水平方向に三分割した場合を例示したが、もちろん用途に応じて水平方向に二分割、あるいは四分割以上することも可能である。 <Fifth embodiment of the present invention>
FIG. 12 is a perspective view of a laminated pallet integrated product 51 according to a fifth embodiment of the present invention. In FIG. 12, the laminate 3 is drawn by a two-dot chain line. The laminated pallet integrated product 51 according to the present embodiment is different from the laminated pallet integrated product 1, 21 according to the above embodiment in that the rectangular change surfaces 52a to 52c are divided in the longitudinal direction as a whole. 31 and 41 are different. Specifically, changing surfaces 52a to 52c are formed by front surfaces 53a1 to 53c1 of a plurality of plate-like members 53a to 53c which are divided in the horizontal direction and which are movable independently (in the present embodiment, tilted). According to the above configuration, even when the amount of insertion of the slip sheet I by the suction pad 14 (see FIG. 6A or the like) varies in the horizontal direction, the degree of tilt of the plate members 53a to 53c is controlled by the plate members 53a to 53c. Variations can be made for each 53c to absorb variations in the pushing amount in the horizontal direction. Therefore, according to the present configuration, it is possible to effectively reduce the frictional resistance acting on the slip sheet I over the entire area in the horizontal direction while absorbing the variation in the pressing amount in the horizontal direction. Although FIG. 12 illustrates the case where the changing surface is divided into three parts in the horizontal direction, it is needless to say that the plane may be divided into two parts or four parts or more in the horizontal direction depending on the application.
　もちろん、変化面１２，２３，３２，４４，５２ａ～５２ｃの形態は任意であり、押込みが可能である限りにおいて、上記例示した形態以外の形態をとることが可能である。例えば詳細は割愛するが、図４に示す板状部材１０が、押込みに応じて、傾斜角θ３を変えることなく背面支持部８に近づく、言い換えると傾斜角θ３は一定で積層方向Ｘに平行移動するように構成することも可能である。 Of course, the form of the changing surfaces 12, 23, 32, 44, 52a to 52c is arbitrary, and any form other than the above-described form can be used as long as the pressing is possible. For example, although not described in detail, the plate-like member 10 shown in FIG. 4 approaches the back support 8 without changing the inclination angle θ3 in response to the depression, in other words, the inclination angle θ3 is constant and parallelly moves in the stacking direction X. It is also possible to configure so that
　また、以上の説明では、第二対向領域１１ｂのうち、ガラス板Ｇの上辺から食み出した合紙Ｉと対向する領域に変化面１２，２３，３２，４４，５２ａ～５２ｃを設けた場合を例示したが、もちろんこれ以外の位置に変化面１２，２３，３２，４４，５２を設けることも可能である。例えば、図示は省略するが、ガラス板Ｇの側辺側から食み出した合紙Ｉを吸着保持して、水平方向に合紙Ｉを移動させてパレット２上から排出する場合、第二対向領域１１ｂのうち、ガラス板Ｇの側辺から食み出した合紙Ｉと対向する領域に、変化面１２，２３，３２，４４，５２ａ～５２ｃを設けることも可能である。 In the above description, the case where the changing surfaces 12, 23, 32, 44, 52a to 52c are provided in the region facing the slip sheet I protruding from the upper side of the glass plate G in the second facing region 11b. However, the change surfaces 12, 23, 32, 44, and 52 can be provided at other positions. For example, although not shown in the drawing, when the slip sheet I protruding from the side of the glass plate G is sucked and held, and the slip sheet I is moved in the horizontal direction and discharged from the pallet 2, the second facing It is also possible to provide the changing surfaces 12, 23, 32, 44, 52a to 52c in the area of the area 11b facing the slip sheet I protruding from the side of the glass plate G.
　また、以上の説明では、ガラス板Ｇを積層する際の保護シートとして合紙Ｉを用いた場合を説明したが、もちろんこれに限る必要はない。例えば、合紙以外の紙を保護シートとして使用することも可能である。あるいは、紙以外の材質（例えば樹脂）で形成されたシートを保護シートとして使用することも可能である。要は、ガラス板Ｇを積層した状態でパレット２上に搭載するに際して、又はパレット２上からのガラス板Ｇの取出しに際して、ガラス板Ｇを保護する（ガラス板Ｇを傷付けない）限りにおいて、任意の材質、形態のシートが使用可能である。 In the above description, the case where the slip sheet I is used as the protective sheet when the glass plates G are laminated has been described, but it is needless to say that the present invention is not limited to this. For example, it is also possible to use paper other than interleaving paper as a protection sheet. Alternatively, a sheet made of a material other than paper (for example, resin) can be used as the protection sheet. The point is that, when the glass sheets G are mounted on the pallet 2 in a stacked state, or when the glass sheets G are taken out from the pallet 2, the glass sheets G can be protected (as long as the glass sheets G are not damaged). Sheets of the following materials and forms can be used.
　また、以上の説明では、積層体パレット一体品１を梱包して梱包体１５とした状態で出荷先等に搬送し、搬送先で開梱（ガラス板Ｇの取出し）を行う場合を例示したが、本発明に係る積層体パレット一体品１，２１，３１，４１，５１は、上記以外の用途に適用することも可能である。すなわち、ガラス板Ｇの取出し時にガラス板Ｇが縦姿勢で積層された状態でパレット２上に搭載されている限りにおいて、その形態は任意であり、パレット２が必ずしも梱包を前提とした形態である必要はない。例えば図示は省略するが、搬送時にはガラス板Ｇ（積層体３）が水平姿勢で積層された状態で、ガラス板Ｇの取出し時には、ガラス板Ｇが縦姿勢で積層された状態となるように構成したパレットに、本発明を適用してもよい。 In the above description, the case where the laminated body pallet integrated product 1 is packed and transported to a shipping destination or the like in the state of the package 15 and unpacking (take-out of the glass plate G) is performed at the transport destination has been exemplified. The laminated body pallet integrated products 1, 21, 31, 41, 51 according to the present invention can be applied to uses other than the above. That is, as long as the glass plates G are stacked on the pallet 2 in a vertically stacked state when the glass plate G is taken out, the form is arbitrary, and the pallet 2 is always a form premised on packing. No need. For example, although not shown, the glass plates G (laminated body 3) are stacked in a horizontal posture during transport, and the glass plates G are stacked in a vertical posture during removal of the glass plate G. The present invention may be applied to a completed pallet.
