Abstract

PROBLEM TO BE SOLVED: To improve working efficiency and productivity by eliminating the use of two types of devices of different structures and delivery operation of a sheet material between the two types of devices, while properly arranging the sheet material on a surface side of a glass plate on a pallet without causing crinkles etc. by surely applying an appropriate tensile force to the sheet material.SOLUTION: In supplying and arranging the sheet material 3, which is obtained by cutting a belt-like sheet base material 4 conveyed from the upstream side to the downstream side into a predetermined length at the downstream side position, onto the surface side of the glass plate 2 on the pallet 13, a device for supplying the sheet material is provided with a pair of upstream-end holding means 7 and a pair of downstream-end holding means 8 respectively holding an upstream side end and a downstream side end of both side ends in the width direction of the sheet material 3. The holding means 7, 8 are respectively moved in the width direction of the sheet material 3 and in the upstream/downstream direction, so as to supply and arrange the sheet material 3 in the state held by the holding means 7, 8 onto the surface of the glass plate 2 on the pallet 13.

Description

本発明は、パレット上にガラス板とシート材とを交互に配列させるために、帯状シート元材を下流側部位で一定長さに切断してなるシート材をガラス板の表面側に供給して配置させるシート材供給装置及びシート材供給方法に関する。   In the present invention, in order to alternately arrange the glass plate and the sheet material on the pallet, a sheet material obtained by cutting the strip-shaped sheet base material into a certain length at the downstream side portion is supplied to the surface side of the glass plate. The present invention relates to a sheet material supply apparatus and a sheet material supply method to be arranged.

周知のように、ガラス板の輸送や保管用等として、パレット上にガラス板を縦置きや平置きの状態で積載する場合には、ガラス板同士の直接接触による擦り傷の発生防止や、輸送中のガラス板の破損防止等を目的として、ガラス板の相互間に、緩衝材やスペーサとしてのシート材が介装される。したがって、パレット上には、ガラス板とシート材とを交互に配置させてなるガラス板積層体が形成される。   As is well known, when a glass plate is mounted on a pallet in a vertical or flat state for transportation or storage of the glass plate, the occurrence of scratches due to direct contact between the glass plates can be prevented. For the purpose of preventing breakage of the glass plate, a buffer material or a sheet material as a spacer is interposed between the glass plates. Therefore, the glass plate laminated body which arranges a glass plate and a sheet material alternately is formed on a pallet.

その場合、シート材としては、種々のものが使用されるが、その大半は薄肉軽量である関係上、その取り扱いは困難化を余儀なくされているのが実情である。そのため、パレット上において、ガラス板の表面側（露出面側）にシート材を重ね合わせるように配置させる作業は、手作業で行うには限界があるため、専用の装置が使用されているのが実情である。   In that case, various types of sheet materials are used, but most of them are thin and light, and the fact is that their handling is forced to be difficult. Therefore, on the pallet, the work of placing the sheet material so as to overlap the surface side (exposed surface side) of the glass plate has a limit to be performed manually, so a dedicated device is used. It is a fact.

具体的には、特許文献１によれば、合紙ロールから帯状の合紙を引き出す合紙引出装置と、引き出された合紙を切り取る合紙切断装置と、切断された合紙を吸着パッドにより保持させ且つ該合紙を回転移動させてパレットに縦積みされているガラス板に積層させる合紙挿入装置とを備えた合紙供給装置が開示されている。   Specifically, according to Patent Document 1, a slip sheet drawing device that pulls out a strip-shaped slip sheet from a slip sheet roll, a slip sheet cutting device that cuts out the slipped slip sheet, and a cut slip sheet by a suction pad. There is disclosed an interleaf feeding device including an interleaf insertion device that holds the interleaving paper and rotates the interleaving paper to be stacked on a glass plate that is vertically stacked on a pallet.

しかしながら、この合紙供給装置の構成要素である合紙挿入装置は、切断された合紙を吸着パッドで保持して単にパレット上のガラス板の表面側に積層させるものであるため、合紙がガラス板の表面側に達した際には、当該合紙にしわや弛み等が発生する虞がある。それにも拘らず、このような事態に対しては適切な対策が講じられていない。   However, the slip sheet inserting device, which is a component of the slip sheet supply device, holds the cut slip sheet with a suction pad and simply stacks it on the surface side of the glass plate on the pallet. When the surface of the glass plate is reached, there is a risk that wrinkles or slack will occur in the slip sheet. Nevertheless, no appropriate measures have been taken for this situation.

これに対して、例えば特許文献２によれば、同文献の図５に示すシート材切断装置の動作により、切断されたシート材に幅方向及び上下方向の張力を生じさせた後、このシート材を、同文献の図２に示すシート材保持装置により受け取り、該保持装置でシート材に幅方向の張力を生じさせて、該シート材をパレット上のガラス板の表面側に積層させるシート材積込装置が開示されている。このシート材積込装置によれば、シート材に不当なしわを発生させることなくガラス板とシート材とを交互に配置させて、パレット上に適切なガラス板積層体を形成し得ることが期待できる。   On the other hand, according to Patent Document 2, for example, the sheet material cutting apparatus shown in FIG. 5 of the same document generates tension in the width direction and the vertical direction on the cut sheet material, and then the sheet material. 2 is received by the sheet material holding device shown in FIG. 2 of the same document, and the sheet material is loaded on the surface side of the glass plate on the pallet by generating tension in the width direction of the sheet material with the holding device. An apparatus is disclosed. According to this sheet material loading device, it can be expected that an appropriate glass plate laminate can be formed on the pallet by alternately arranging the glass plates and the sheet material without causing undue wrinkles in the sheet material. .

ところで、上述の特許文献２に開示されたシート材積込装置によれば、シート材切断装置でシート材の幅方向と上下方向との双方に一旦張力を付与した後、そのシート材を、シート材保持装置により受け取ってパレット上のガラス板の表面側まで移動させる必要がある。すなわち、シート材を切断してから、該シート材をパレット上のガラス板の表面側に配置させるまでの間に、異なる構造の二種の装置が必要となり、装置全体としての大型化や複雑化さらには製作コストの高騰を招く。   By the way, according to the sheet material loading device disclosed in Patent Document 2 described above, after the tension is once applied to both the width direction and the vertical direction of the sheet material by the sheet material cutting device, the sheet material is used as the sheet material. It must be received by the holding device and moved to the surface side of the glass plate on the pallet. In other words, two types of devices with different structures are required between cutting the sheet material and placing the sheet material on the surface side of the glass plate on the pallet, increasing the size and complexity of the entire device. In addition, the production cost increases.

しかも、上記の異なる構造の二種の装置間でシート材の受け取りを行わせねばならず、その受け取り動作が煩雑且つ面倒になると共に、作業時間の長期化ひいては作業能率の悪化を招くという難点がある。加えて、シート材の受け取り動作は、必ずしも支障なく適切に行えるとは限らず、受け取り時に作業ミス等が発生する余地も残存している。   In addition, the sheet material must be received between the two types of apparatuses having the different structures described above, and the receiving operation is complicated and troublesome, and the work time is prolonged and the work efficiency is deteriorated. is there. In addition, the sheet material receiving operation is not necessarily performed properly without any trouble, and there is still room for an operation error or the like to occur at the time of receiving.

また、上記のシート材切断装置において、シート材に上下方向の張力を付与する手段としては、該シート材の下端部を下方に引き下げる際に、その上方でシート材に吸引力による抵抗を付与しているに過ぎないため、シート材に十分な上下方向の張力を付与することが困難となる。しかも、このシート材を受け取ったシート材保持装置は、シート材の幅方向両側部と上縁部とのみを保持して幅方向の張力を付与するものであるため、上下方向の張力が付与された状態を維持して、シート材をパレット上のガラス板の表面側まで移動させることが困難となる。   In the sheet material cutting apparatus, as a means for applying a vertical tension to the sheet material, when the lower end portion of the sheet material is pulled downward, a resistance due to a suction force is applied to the sheet material above it. Therefore, it is difficult to apply sufficient vertical tension to the sheet material. In addition, the sheet material holding device that receives the sheet material holds only both the widthwise side portions and the upper edge portion of the sheet material and applies the tension in the width direction. It is difficult to move the sheet material to the surface side of the glass plate on the pallet while maintaining the state.

以上の問題は、近年におけるガラス板の大型化（例えば四辺が２ｍ以上の大型化）及びこれに伴うシート材の大型化に伴って、より一層顕著化される。また、以上の問題は、上述のようにパレット上に縦置きで配置されるガラス板及びシート材に限らず、平置きで配置されるガラス板及びシート材についても同様に生じ得る。   The above problems become more prominent with the recent increase in the size of glass plates (for example, the increase in size on a side of 2 m or more) and the accompanying increase in the size of sheet materials. In addition, the above-described problems are not limited to the glass plate and the sheet material that are arranged vertically on the pallet as described above, but may occur similarly for the glass plate and the sheet material that are arranged flat.

本発明は、上記事情に鑑み、異なる構造の二種の装置の使用及びその二種の装置間でのシート材の受け渡し動作を不要にして、装置の小型化や簡素化さらには作業能率の向上や生産性の改善を図ると共に、シート材に適切な張力を確実に付与してしわの発生等を招くことなく該シート材をパレット上のガラス板の表面側に適正に配置させることを技術的課題とする。   In view of the above circumstances, the present invention eliminates the use of two types of apparatuses having different structures and the sheet material transfer operation between the two types of apparatuses, thereby reducing the size and simplifying the apparatus and improving the work efficiency. To improve the productivity of the sheet and ensure that the sheet material is properly placed on the surface of the glass plate on the pallet without causing wrinkles and the like by reliably applying an appropriate tension to the sheet material. Let it be an issue.

上記技術的課題を解決するために創案された本発明に係る装置は、パレット上にガラス板とシート材とを交互に積層してなるガラス板積層体を形成するために、上流側から下流側に向かって送られる帯状シート元材を一定長さに切断し、その切断後のシート材をガラス板の表面側に供給して配置させるように構成したシート材供給装置であって、前記帯状シート元材を切断してなるシート材の幅方向両側端における上流側端部及び下流側端部をそれぞれ保持する一対の上流端保持手段及び一対の下流端保持手段を備え、これら各保持手段のそれぞれの離間長さが前記シート材の幅方向及び上下流方向に伸張するように構成すると共に、前記シート材を前記各保持手段が保持した状態で前記パレット上のガラス板の表面側に供給して配置させるように構成したことに特徴づけられる。   The apparatus according to the present invention, which was created to solve the above technical problem, is formed from an upstream side to a downstream side in order to form a glass plate laminate formed by alternately laminating glass plates and sheet materials on a pallet. A sheet material supply apparatus configured to cut a strip-shaped sheet base material sent toward a predetermined length and to supply and arrange the cut sheet material on the surface side of the glass plate, the strip-shaped sheet Each of the holding means includes a pair of upstream end holding means and a pair of downstream end holding means for holding the upstream end and the downstream end at both ends in the width direction of the sheet material formed by cutting the original material. And the sheet material is supplied to the surface side of the glass plate on the pallet while being held by the holding means. Place Characterized in that the sea urchin configuration.

このような構成によれば、帯状シート元材から切り出されたシート材は、一対の上流端保持手段と一対の下流端保持手段とによって少なくとも四隅が保持されると共に、これらの各保持手段は、それぞれの離間長さがシート材を保持した状態で幅方向と上下流方向とに伸張するように構成されている。そして、シート材は、これらの各保持手段により保持された状態でパレット上のガラス板の表面側に配置されることになるため、少なくともその配置時までに、各保持手段を適宜幅方向及び上下流方向に移動させれば、シート材には、幅方向の張力と上下流方向の張力とが同時に付与された状態となる。したがって、シート材は、各保持手段による上記張力によって何れの方向に対してもしわやたるみ等の発生が回避された状態で、パレット上のガラス板（縦置き及び平置きの何れでもよい）の表面側に配置される。そして、このような状態にあるシート材の表面側に後続のガラス板を配置させれば、各ガラス板の相互間にシート材が支障なく円滑に介装される。以上のような動作は、一対の上流端保持手段及び一対の下流端保持手段を有する実質的に一台の装置で行うことができるため、装置の小型化や簡素化さらには製作コストの低廉化が図られると共に、異なる構造の二台の装置間でシート材の受け渡しを行う必要もなくなるため、作業能率の向上ひいては生産性の改善が図られる。しかも、シート材がガラス板の表面側に配置される際には、各保持手段が積極的にシート材を所要の方向に引っ張った状態となるため、シート材に幅方向とこれに直角な上下流方向とに確実且つ十分な張力を付与させることが可能となり、パレット上に形成されるガラス板積層体には、不当な状態で介装されるシート材が存在し難くなる。   According to such a configuration, at least four corners of the sheet material cut out from the band-shaped sheet base material are held by the pair of upstream end holding means and the pair of downstream end holding means, and each of these holding means is Each separation length is configured to extend in the width direction and the upstream / downstream direction while holding the sheet material. Since the sheet material is arranged on the surface side of the glass plate on the pallet in a state of being held by each of these holding means, at least by the time of the arrangement, each holding means is appropriately placed in the width direction and above. If the sheet material is moved in the downstream direction, the sheet material is in a state in which the tension in the width direction and the tension in the upstream and downstream directions are simultaneously applied. Therefore, the sheet material is a glass plate on the pallet (either vertically or flatly placed) in a state where generation of wrinkles and sagging in any direction is avoided by the above tension by each holding means. It is arranged on the surface side. And if a subsequent glass plate is arrange | positioned on the surface side of the sheet | seat material in such a state, a sheet | seat material will be smoothly interposed between each glass plate without trouble. Since the operation as described above can be performed by substantially one apparatus having a pair of upstream end holding means and a pair of downstream end holding means, the apparatus can be downsized and simplified, and the manufacturing cost can be reduced. In addition, since it is not necessary to transfer the sheet material between two apparatuses having different structures, the work efficiency can be improved and the productivity can be improved. Moreover, when the sheet material is disposed on the surface side of the glass plate, each holding means positively pulls the sheet material in the required direction. It becomes possible to apply a certain and sufficient tension in the downstream direction, and it is difficult for the glass plate laminate formed on the pallet to have a sheet material interposed in an inappropriate state.

この場合、前記シート材を前記各保持手段が保持してから前記ガラス板の表面側に配置させるまでの間に、前記一対の上流端保持手段と前記一対の下流端保持手段との上下流方向の移動量を異ならせることにより、該シート材に上下流方向の張力を付与すると共に、前記一対の上流端保持手段のそれぞれの幅方向の移動量と前記一対の下流端保持手段のそれぞれの幅方向の移動量とを同等に異ならせることにより、該シート材に幅方向の張力を付与するように構成されていることが好ましい。ここで、「移動量が異なる」とは、移動方向が相違すれば、移動量の正と負との符号が相違するため、移動量の絶対値が同一でも、移動量としては異なることを意味する。また。一部の保持手段の「移動量」は零の場合も有り得る。   In this case, the upstream and downstream directions of the pair of upstream end holding means and the pair of downstream end holding means between the holding of the sheet material and the placement of the sheet material on the surface side of the glass plate The amount of movement of the pair of upstream end holding means is applied to the sheet material, and the amount of movement in the width direction of the pair of upstream end holding means and the width of the pair of downstream end holding means are varied. It is preferable that the sheet material is configured to be given tension in the width direction by making the amount of movement in the direction equal. Here, “the movement amount is different” means that if the movement direction is different, the sign of the movement amount is different between positive and negative, so that even if the absolute value of the movement amount is the same, the movement amount is different. To do. Also. The “movement amount” of some holding means may be zero.

詳述すると、上下流方向については、一対の上流端保持手段と一対の下流端保持手段とを双方共に下流側に移動させてその移動量を異ならせることにより張力を付与する手法と、一対の上流端保持手段の移動を停止させておいて一対の下流端保持手段のみを下流側に移動させて張力を付与する手法と、一対の下流端保持手段の移動を停止させておいて一対の上流端保持手段を上流側に移動させることにより張力を付与する手法と、一対の上流端保持手段と一対の下流端保持手段とを双方共に上流側に移動させてその移動量の絶対値を異ならせることにより張力を付与する手法とがあるが、何れの場合にも、張力を付与した後に、或いは張力を付与しながら、最終的には、シート材をパレット上のガラス板の表面側の全域または略全域を覆うように配置させる必要がある。また、幅方向については、一対の上流端保持手段の一方及び他方と一対の下流端保持手段の一方及び他方とをそれぞれ相離反するように移動させて張力を付与する手法と、一対の上流端保持手段の一方と一対の下流端保持手段の一方との移動を停止させておいて一対の上流端保持手段の他方と一対の下流端保持手段の他方とを移動させることにより張力を付与する手法と、一対の上流端保持手段の一方及び他方と一対の下流端保持手段の一方及び他方とを同方向に移動させてその移動量を異ならせることにより張力を付与する手法とがある。   More specifically, with respect to the upstream and downstream directions, a method of applying tension by moving both the pair of upstream end holding means and the pair of downstream end holding means to the downstream side and making the amount of movement different from each other, A method of applying tension by stopping the movement of the upstream end holding means and moving only the pair of downstream end holding means downstream, and a pair of upstreams by stopping the movement of the pair of downstream end holding means The method of applying tension by moving the end holding means to the upstream side and the pair of upstream end holding means and the pair of downstream end holding means are both moved to the upstream side so that the absolute values of the movement amounts are different. In any case, after applying the tension or while applying the tension, the sheet material is finally applied to the entire area on the surface side of the glass plate on the pallet or I cover almost the whole area There is a need to be placed in. Further, with respect to the width direction, a method of applying tension by moving one and the other of the pair of upstream end holding means and one and the other of the pair of downstream end holding means away from each other, and a pair of upstream ends A method of applying tension by stopping movement of one of the holding means and one of the pair of downstream end holding means and moving the other of the pair of upstream end holding means and the other of the pair of downstream end holding means. And a method of applying tension by moving one and the other of the pair of upstream end holding means and one and the other of the pair of downstream end holding means in the same direction and making the movement amounts different.

このようにすれば、各保持手段の全てがシート材を保持してからパレット上のガラス板の表面側に到達するまでの間に、一対の上流端保持手段と一対の下流端保持手段との上下流方向に対する移動量の差と、一対の上流端保持手段同士及び一対の下流端保持手段同士のそれぞれの幅方向に対する同等な移動量の差とによって、互いに直角な方向の張力がシート材に付与されるため、各保持手段の張力付与のための動作の正確化のみならず簡素化をも図り得る。   In this way, between all the holding means holding the sheet material and reaching the surface side of the glass plate on the pallet, the pair of upstream end holding means and the pair of downstream end holding means Due to the difference in the amount of movement in the upstream and downstream directions and the difference in the equivalent amount of movement in the width direction between the pair of upstream end holding means and between the pair of downstream end holding means, the tension in the direction perpendicular to each other is applied to the sheet material. Therefore, not only the operation for applying the tension of each holding means but also the accuracy can be simplified.

この構成において、前記一対の上流端保持手段と前記一対の下流端保持手段とを、何れも下流方向へ移動させると共に、その時の各上流端保持手段と各下流端保持手段との移動速度を異ならせることにより、該シート材に上下流方向の張力を付与するように構成されていることが好ましい。   In this configuration, the pair of upstream end holding means and the pair of downstream end holding means are both moved in the downstream direction, and the movement speeds of the upstream end holding means and the downstream end holding means at that time are different. It is preferable that it is comprised so that the tension | tensile_strength of an upstream / downstream direction may be provided to this sheet | seat material.

このようにすれば、帯状シート元材の下流側にパレットが設置されている関係上、パレット上のガラス板の表面側に、互いに直角な方向の張力が付与されたシート材を配置させる作業が、極めて迅速に行われ得る。   In this way, because the pallet is installed on the downstream side of the strip-shaped sheet base material, the work of placing the sheet materials to which tensions in directions perpendicular to each other are provided on the surface side of the glass plate on the pallet is performed. Can be done very quickly.

以上の構成において、前記帯状シート元材の幅方向両側端における下流側端部を前記一対の下流端保持手段により保持させた状態で該一対の下流端保持手段を下流側に移動させ、所定長さ分だけ下流側に移動させた時点で、前記保持前における前記一対の下流端保持手段の直上流側位置で待機していた前記一対の上流端保持手段により前記帯状シート元材の幅方向両側端を保持させ、且つ、該一対の上流端保持手段の直上流側位置で前記帯状シート元材を切断することにより、前記シート材を前記各保持手段により保持させた状態とし、この状態で前記シート材に幅方向の張力と上下流方向の張力とを付与するように構成されていることが好ましい。   In the above-described configuration, the pair of downstream end holding means is moved to the downstream side in a state where the downstream end portions at both side ends in the width direction of the strip-shaped sheet base material are held by the pair of downstream end holding means, and a predetermined length is obtained. Both sides of the strip-shaped sheet base material in the width direction by the pair of upstream end holding means waiting at the position immediately upstream of the pair of downstream end holding means before the holding when moved to the downstream side by that amount. By holding the ends and cutting the strip-shaped sheet base material at a position immediately upstream of the pair of upstream end holding means, the sheet material is held by the holding means, and in this state, It is preferable that the sheet material is configured to be given a tension in the width direction and a tension in the upstream / downstream direction.

このようにすれば、先ず、帯状シート元材の下流側端部を、上下流方向に隣接配置されている一対の上流端保持手段及び一対の下流端保持手段のうち、一対の下流端保持手段のみで保持した状態で、該帯状シート元材を下流側に所定長さ分だけ移動させ、然る後、一対の上流端保持手段により帯状シート元材を保持し、その直後に該一対の上流端保持手段の直上流側位置で帯状シート元材を切断することにより、所定の大きさの１枚のシート材が各保持手段により保持された状態となる。この後は、既に述べたように、当該シート材を保持している各保持手段が適宜幅方向及び上下流方向に移動することにより、当該シート材に互いに直角な方向の張力が付与され、この状態で各保持手段が当該シート材をパレット上のガラス板の表面側に配置させる。従って、各上流端保持手段と各下流端保持手段との連係動作が良好に行われ、シート材を適切な張力付与状態でパレット上まで円滑に移動させることが可能となる。   If it does in this way, first, a downstream end part of a strip | belt-shaped sheet | seat base material will be a pair of downstream end holding means among a pair of upstream end holding means and a pair of downstream end holding means which are adjacently arranged in the up-downstream direction. In this state, the belt-like sheet base material is moved downstream by a predetermined length, and thereafter, the belt-like sheet base material is held by a pair of upstream end holding means, and immediately after the pair of upstream sheets By cutting the strip-shaped sheet base material at a position immediately upstream of the end holding means, one sheet material having a predetermined size is held by each holding means. Thereafter, as described above, each holding means holding the sheet material appropriately moves in the width direction and the upstream / downstream direction, so that tension in a direction perpendicular to each other is applied to the sheet material. In the state, each holding means arranges the sheet material on the surface side of the glass plate on the pallet. Therefore, the linking operation between each upstream end holding means and each downstream end holding means is performed satisfactorily, and the sheet material can be smoothly moved onto the pallet with an appropriate tension applied.

以上の構成において、前記一対の上流端保持手段のうち一方の上流端保持手段と、前記一対の下流端保持手段のうち一方の下流端保持手段とが、前記シート材の幅方向両側のうち一方側に存する支持部材に共用して支持されると共に、前記一対の上流端保持手段のうち他方の上流端保持手段と、前記一対の下流端保持手段のうち他方の下流端保持手段とが、前記シート材の幅方向両側のうち他方側に存する支持部材に共用して支持されていることが好ましい。   In the above configuration, one upstream end holding means of the pair of upstream end holding means and one downstream end holding means of the pair of downstream end holding means are one of both sides in the width direction of the sheet material. And the other upstream end holding means of the pair of upstream end holding means, and the other downstream end holding means of the pair of downstream end holding means, It is preferable that the sheet member is supported in common with the support member existing on the other side of both sides in the width direction.

このようにすれば、二列に並設された各支持部材に沿って各上流端保持手段及び各下流端保持手段が上下流方向に移動すると共に、この移動に伴って、各保持手段に支持されているシート材が、パレット上のガラス板の表面側近傍に到達し得ることになる。これにより、帯状シート元材の切断からその切断後のシート材の移動を、簡単な構造の装置によって行わせることが可能となる。   In this way, the upstream end holding means and the downstream end holding means move in the upstream / downstream direction along the support members arranged in two rows, and are supported by the holding means along with this movement. The sheet material being made can reach the vicinity of the surface side of the glass plate on the pallet. Thereby, the movement of the sheet material after the cutting of the strip-shaped sheet base material can be performed by an apparatus having a simple structure.

この場合、前記両支持部材は、前記パレットの幅方向両側に配設されていることが好ましい。   In this case, it is preferable that the both support members are disposed on both sides in the width direction of the pallet.

このようにすれば、両支持部材がパレットに対して適切に配置されているため、帯状シート元材からの切断後のシート材をパレット上の積層位置まで移動させる動作が、各保持手段により円滑に行われ得る。   In this case, since both the supporting members are appropriately arranged with respect to the pallet, the operation of moving the sheet material after cutting from the belt-like sheet base material to the stacking position on the pallet is smoothly performed by each holding means. Can be done.

以上の構成において、前記各保持手段は、シート材の幅方向における両側端を把持するクランプ機構を備えていることが好ましい。   In the above configuration, each holding means preferably includes a clamp mechanism that grips both side ends in the width direction of the sheet material.

このようにすれば、クランプ機構がシート材の四隅を確実に把持し得るため、各保持手段がシート材に所要の張力を付与する上で有利となる。   In this way, the clamp mechanism can surely grip the four corners of the sheet material, which is advantageous when each holding means applies a required tension to the sheet material.

以上の構成において、前記シート材は、伸縮性を有していてもよい。   In the above configuration, the sheet material may have stretchability.

このようにすれば、各保持手段により、しわやたるみが生じ易い伸縮性を有するシート材に張力が付与され、これにより当該シート材は適正な平面状態となり得る。なお、シート材としては、伸縮性を有する樹脂シート、特に発泡ポリエチレン等からなる発泡樹脂シートであってもよく、伸縮性を殆ど有しない合紙等の紙類であってもよい。   If it does in this way, a tension | tensile_strength will be provided to the sheet material which has a stretching property which is easy to produce a wrinkle and sagging by each holding means, Thereby, the said sheet material can be in an appropriate plane state. In addition, as a sheet material, the resin sheet which has a stretching property, especially the foamed resin sheet which consists of foaming polyethylene etc. may be sufficient, and papers, such as a slip sheet, which hardly has a stretching property may be sufficient.

上記技術的課題を解決するために創案された本発明に係る方法は、パレット上にガラス板とシート材とを交互に積層してなるガラス板積層体を形成するために、上流側から下流側に向かって送られる帯状シート元材を下流側部位で一定長さに切断し、その切断後のシート材をガラス板の表面側に供給して配置させるシート材供給方法であって、前記帯状シート元材を切断してなる前記シート材の幅方向両側端における下流側端部及び上流側端部を保持する一対の下流端保持手段及び一対の上流端保持手段を、それぞれの離間長さが前記シート材の幅方向及び上下流方向に伸張するようにし、これら各保持手段が前記シート材を保持した状態で該シート材を前記パレット上のガラス板の表面側に供給して配置させることに特徴づけられる。   The method according to the present invention, which was created to solve the above technical problem, is to form a glass plate laminate formed by alternately laminating glass plates and sheet materials on a pallet, from the upstream side to the downstream side. A sheet material supply method in which a band-shaped sheet base material fed toward the sheet is cut into a certain length at a downstream portion, and the sheet material after the cutting is supplied and arranged on the surface side of the glass plate, which is the band-shaped sheet The pair of downstream end holding means and the pair of upstream end holding means for holding the downstream end and the upstream end at the both ends in the width direction of the sheet material formed by cutting the original material, each having a separation length of The sheet material is extended in the width direction and the upstream / downstream direction, and the sheet material is supplied and arranged on the surface side of the glass plate on the pallet in a state where each holding means holds the sheet material. It is attached.

このような構成を備えた本発明に係る方法についての説明事項（作用効果を含む）は、この欄の冒頭で述べた本発明に係る装置についての説明事項と実質的に同一である。   The explanation (including the effects) of the method according to the present invention having such a configuration is substantially the same as the explanation of the apparatus according to the present invention described at the beginning of this section.

以上のように本発明によれば、帯状シート元材から切り出されたシート材は、一対の上流端保持手段と一対の下流端保持手段とによって少なくとも四隅が保持され、これらの保持手段によって幅方向及び上下流方向に張力が付与されると共に、このような状態で各保持手段がシート材をパレット上のガラス板の表面側に配置させることになる。そして、このような動作は、一対の上流端保持手段及び一対の下流端保持手段を有する実質的に一台の装置で行うことができるため、装置の小型化や簡素化さらには製作コストの低廉化が図られると共に、異なる構造の二台の装置間でシート材の受け渡しを行う必要もなくなるため、作業能率の向上ひいては生産性の改善が図られる。しかも、シート材がガラス板の表面側に配置される際には、シート材に対して幅方向と上下流方向とに確実且つ十分な張力を付与させることが可能となり、パレット上に形成されるガラス板積層体には、不当な状態で介装されるシート材が存在し難くなる。   As described above, according to the present invention, at least four corners of the sheet material cut out from the band-shaped sheet base material are held by the pair of upstream end holding means and the pair of downstream end holding means, and the width direction by these holding means And tension | tensile_strength is provided to an up-down direction, and each holding means will arrange | position a sheet material on the surface side of the glass plate on a pallet in such a state. Such an operation can be performed by a substantially single apparatus having a pair of upstream end holding means and a pair of downstream end holding means. Therefore, the apparatus can be downsized and simplified, and the manufacturing cost can be reduced. In addition, since it is not necessary to transfer the sheet material between two apparatuses having different structures, the work efficiency can be improved and the productivity can be improved. Moreover, when the sheet material is disposed on the surface side of the glass plate, it is possible to apply a certain and sufficient tension to the sheet material in the width direction and the upstream / downstream direction, and the sheet material is formed on the pallet. In a glass plate laminated body, it becomes difficult for the sheet | seat material interposed in an unfair state to exist.

以下、本発明の実施形態を添付図面に基づいて説明する。なお、以下の実施形態では、パレット上に縦置きでガラス板とシート材とを交互に配置させる場合を例示する。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, in the following embodiment, the case where a glass plate and a sheet | seat material are arrange | positioned alternately on a pallet vertically is illustrated.

図１は、本発明の第一実施形態に係るシート材供給装置１の全体構成を示す概略斜視図である。なお、このシート材供給装置１で配置対象となる略矩形のガラス板２は、四辺の長さがそれぞれ１ｍ以上で且つ厚みが０．５〜３．０ｍｍであり、また略矩形のシート材３は、四辺の長さがそれぞれ１．０５ｍ以上で且つ厚みが０．０５〜２．００ｍｍであって、シート材３の幅方向両側と上側とはガラス板２の幅方向両辺及び上辺から食み出している。そして、シート材３としては、伸縮性を有する発泡ポリエチレン等からなる発泡樹脂シートが使用される。   FIG. 1 is a schematic perspective view showing the overall configuration of a sheet material supply apparatus 1 according to the first embodiment of the present invention. The substantially rectangular glass plate 2 to be arranged in the sheet material supply apparatus 1 has a length of 4 m on each side and a thickness of 0.5 to 3.0 mm, and a substantially rectangular sheet material 3. The length of each of the four sides is 1.05 m or more and the thickness is 0.05 to 2.00 mm, and both sides in the width direction and the upper side of the sheet material 3 are eaten from both sides and the upper side in the width direction of the glass plate 2. I'm out. And as the sheet | seat material 3, the foamed resin sheet which consists of a foaming polyethylene etc. which has a stretching property is used.

図１に示すように、シート材供給装置１は、帯状シート元材４を上流側でロール状に巻回してなる元材ロール５と、元材ロール５から引き出された帯状シート元材４をその下流側端部で切断する切断手段６と、切断手段６の下方に配設され且つ切断後のシート材３を保持する一対の上端保持手段７及び一対の下端保持手段８とを有する。   As shown in FIG. 1, the sheet material supply apparatus 1 includes a base material roll 5 formed by winding a strip-shaped sheet base material 4 in a roll shape on the upstream side, and a strip-shaped sheet base material 4 drawn from the base material roll 5. It has a cutting means 6 for cutting at its downstream end, and a pair of upper end holding means 7 and a pair of lower end holding means 8 which are disposed below the cutting means 6 and hold the cut sheet material 3.

元材ロール５から切断手段６に至るまでの経路には、帯状シート元材４の送り移動を円滑に行わせるための各種のロールが配列されている。詳述すると、この経路には、上流側から順に、元材ロール５から帯状シート元材４を挟持して引き出す引出ニップロール９と、帯状シート元材４の引き出し寸法を一定範囲に調整するダンサーロール１０と、帯状シート元材４を所要の経路に沿わせるための多数のガイドロール１１と、帯状シート元材４の下流側端部を挟持して切断手段６に送り出すための送出ニップロール１２とが配列されている。   In the path from the base material roll 5 to the cutting means 6, various rolls for smoothly feeding the belt-like sheet base material 4 are arranged. More specifically, in this path, in order from the upstream side, a pull-out nip roll 9 that sandwiches and pulls out the strip-shaped sheet base material 4 from the base material roll 5 and a dancer roll that adjusts the pull-out dimension of the strip-shaped sheet base material 4 to a certain range. 10, a number of guide rolls 11 for causing the strip-shaped sheet base material 4 to follow a required path, and a delivery nip roll 12 for sandwiching the downstream end of the strip-shaped sheet base material 4 and feeding it to the cutting means 6. It is arranged.

切断後におけるシート材３の幅方向両側端を保持する一対の上端保持手段７及び一対の下端保持手段８は、それぞれシート材３の幅方向両側端を挟持して保持するクランプ機構７ａ、８ａを有する。そして、これらの各保持手段７、８は、シート材３を保持した状態で幅方向（Ａ―Ａ方向）及び上下方向（Ｂ―Ｂ方向）に移動するように構成されている。換言すれば、この計四つの保持手段７、８は、それぞれの離間長さが幅方向及び上下方向に可変となるように（詳しくは伸張するように）構成されている。そして、これらの各保持手段７、８は、幅方向移動及び上下方向移動を適宜行うことによって、シート材３に幅方向の張力及び上下方向の張力を同時に付与し、このような状態を維持して、シート材３をパレット１３上のガラス板２の表面側に配置させるように構成されている。   The pair of upper end holding means 7 and the pair of lower end holding means 8 that hold both side ends in the width direction of the sheet material 3 after cutting include clamp mechanisms 7 a and 8 a that sandwich and hold the both side ends in the width direction of the sheet material 3, respectively. Have. The holding means 7 and 8 are configured to move in the width direction (AA direction) and the vertical direction (BB direction) while holding the sheet material 3. In other words, the total of the four holding means 7 and 8 are configured so that the distance between them can be varied in the width direction and the vertical direction (specifically, it extends). Each of these holding means 7 and 8 applies the width direction tension and the vertical direction tension to the sheet material 3 by appropriately performing the width direction movement and the vertical direction movement, and maintains such a state. Thus, the sheet material 3 is arranged on the surface side of the glass plate 2 on the pallet 13.

各保持手段７、８の支持構造を説明すると、図２に示すように、パレット１３の幅方向両側方にはそれぞれ支持部材１４が配設されると共に、これらの支持部材１４は、基台部１５に形成された前後方向（表裏方向または積層方向）に延びるレール１５ａにスライド可能に支持されている。これにより、各保持手段７、８は、縦置きされたガラス板２とシート材３との交互配置の進行によって、最表面側に存するガラス板２の積層位置が変化しても、そのガラス板２に対して常に一定の位置関係を維持できるようになっている。   The support structure of each holding means 7 and 8 will be described. As shown in FIG. 2, support members 14 are disposed on both sides in the width direction of the pallet 13, and these support members 14 are each a base portion. 15 is slidably supported by a rail 15a formed in 15 extending in the front-rear direction (front-back direction or stacking direction). Thereby, each holding means 7 and 8 is the glass plate even if the lamination position of the glass plate 2 which exists in the outermost surface side changes with the progress of the alternate arrangement of the vertically placed glass plate 2 and the sheet material 3. 2 can always maintain a fixed positional relationship.

更に、これらの支持部材１４の表面部（前面部）には、上下方向に延びるガイド板材１６がそれぞれ固定されると共に、これらのガイド板材１６の幅方向内側表面には、上下方向に延びるレール１７が突設され、且つ、これらのレール１７に各保持手段７、８の本体部７ｘ、８ｘがスライド可能に支持されている。また、これらのガイド板材１６の幅方向外側表面には、上下方向に延びる凸状体１８がそれぞれ突設され、これらの凸状体１８の内側面に固定されたラック１９に、各保持手段７、８の本体部７ｘ、８ｘに付設されたモータ７ｂ、８ｂを回転駆動源とするピニオン７ｃ、８ｃがそれぞれ噛合している。ここで、「上下方向」とは、鉛直方向に対して上方が後方側（裏面側）に移行するように傾斜した方向を意味している。   Further, guide plate members 16 extending in the vertical direction are respectively fixed to the surface portions (front portions) of the support members 14, and rails 17 extending in the vertical direction are provided on the inner surfaces in the width direction of the guide plate materials 16. The main body portions 7x and 8x of the holding means 7 and 8 are slidably supported by these rails 17. Further, convex bodies 18 extending in the vertical direction are respectively provided on the outer surfaces in the width direction of the guide plate members 16, and each holding means 7 is mounted on a rack 19 fixed to the inner surface of the convex bodies 18. , 8 have pinions 7c and 8c engaged with motors 7b and 8b attached to the body portions 7x and 8x as rotational drive sources, respectively. Here, the “up and down direction” means a direction inclined so that the upper side moves to the rear side (back side) with respect to the vertical direction.

従って、各保持手段７、８はそれぞれ、クランプ機構７ａ、８ａと本体部７ｘ、８ｘとモータ７ｂ、８ｂとピニオン７ｃ、８ｃとが一体となって上下方向に移動すると共に、これらのモータ７ｂ、８ｂは回転速度が可変調整可能とされ、これに伴って、各保持手段７、８の上下方向移動速度も可変調整可能とされている。そして、シート材３に上下方向の張力を付与する際には、一対の上端保持手段７の下方への移動速度よりも、一対の下端保持手段８の下方への移動速度の方が高速とされている。これにより、これらの保持手段７、８のクランプ機構７ａ、８ａにより挟持されたシート材３は、下端部の下方への移動量の方が上端部の下方への移動量よりも大きくなり、これに起因して、シート材３に上下方向の張力が付与されるようになっている。   Accordingly, the holding means 7 and 8 are respectively moved in the vertical direction by the clamp mechanisms 7a and 8a, the main body portions 7x and 8x, the motor 7b and 8b and the pinions 7c and 8c, and the motors 7b and 8c. In 8b, the rotation speed can be variably adjusted, and accordingly, the vertical movement speed of each holding means 7 and 8 can also be variably adjusted. When the vertical tension is applied to the sheet material 3, the lower moving speed of the pair of lower end holding means 8 is higher than the lower moving speed of the pair of upper end holding means 7. ing. As a result, the sheet material 3 held by the clamping mechanisms 7a and 8a of the holding means 7 and 8 has a lower movement amount of the lower end portion than a lower movement amount of the upper end portion. Due to this, a vertical tension is applied to the sheet material 3.

一方、シート材３に幅方向の張力を付与する手段は、図３に示すように、各保持手段７、８の本体部７ｘ、８ｘに固定されたナット部材７ｄ、８ｄと、これらのナット部材７ｄ、８ｄの雌ねじ部に螺合し且つモータ７ｅ、８ｅによりそれぞれ回転駆動されるねじ軸７ｆ、８ｆとからなるボールねじ機構７ｇ、８ｇが、クランプ機構７ａ、８ａを幅方向に移動させる構成とされている。そして、シート材３に幅方向の張力を付与する際には、一対の上端保持手段７のそれぞれのモータ７ｅを回転させて、両上端保持手段７のクランプ機構７ａをそれぞれ幅方向の相離反する方向に移動させる。これと同時に、一対の下端保持手段８のそれぞれのモータ８ｅも回転させて、両下端保持手段８のクランプ機構８ａをそれぞれ幅方向の相離反する方向に移動させる。これにより、これらの各クランプ機構７ａ、８ａに挟持されているシート材３に幅方向の張力が付与されるようになっている。   On the other hand, as shown in FIG. 3, the means for applying the tension in the width direction to the sheet material 3 includes nut members 7d and 8d fixed to the body portions 7x and 8x of the holding means 7 and 8, and these nut members. The ball screw mechanisms 7g and 8g, which are screwed into the female screw portions of 7d and 8d and are rotationally driven by the motors 7e and 8e, respectively, move the clamp mechanisms 7a and 8a in the width direction. Has been. When applying a tension in the width direction to the sheet material 3, the respective motors 7 e of the pair of upper end holding means 7 are rotated so that the clamp mechanisms 7 a of the upper end holding means 7 are separated from each other in the width direction. Move in the direction. At the same time, the motors 8e of the pair of lower end holding means 8 are also rotated, and the clamp mechanisms 8a of the both lower end holding means 8 are moved in mutually opposite directions in the width direction. Thereby, the tension | tensile_strength of the width direction is provided to the sheet | seat material 3 currently clamped by these each clamp mechanism 7a, 8a.

次に、上記の構成を備えたシート材供給装置１の作用を説明する。なお、以下の説明に際して参照する図４〜図７は、便宜上、支持部材１４や各保持手段７、８の駆動機構等の図示を省略するが、その省略した部位についても、図１〜図３に示す符号を参酌する。   Next, the operation of the sheet material supply apparatus 1 having the above configuration will be described. 4 to 7 referred to in the description below, for convenience, illustration of the support member 14 and the drive mechanism of each holding means 7 and 8 is omitted, but the omitted parts are also shown in FIGS. Consider the symbols shown in.

先ず、帯状シート元材４からシート材３を切り出す前の初期段階においては、図４に示すように、一対の上端保持手段７の直下方に一対の下端保持手段８が近接して配置され、これらの各保持手段７、８のクランプ機構７ａ、８ａは全て開状態にある。このような状態から、図５に示すように、送出ニップロール１２が、帯状シート元材４を下方に送り出し、帯状シート元材４の下端部が、一対の下端保持手段８を通過した時点で、送出ニップロール１２による送り出しを一時的に停止させる。この停止時に、一対の下端保持手段８のクランプ機構８ａが閉状態となって、帯状シート元材４の下端部における幅方向両側端を挟持して保持する。なお、この時点では、一対の上端保持手段７のクランプ機構７ａは依然として開状態にある。   First, in the initial stage before cutting out the sheet material 3 from the strip-shaped sheet base material 4, as shown in FIG. 4, a pair of lower end holding means 8 is disposed in the vicinity immediately below the pair of upper end holding means 7, All of the clamp mechanisms 7a and 8a of the holding means 7 and 8 are open. From such a state, as shown in FIG. 5, when the delivery nip roll 12 sends the strip-shaped sheet base material 4 downward, and the lower end portion of the strip-shaped sheet base material 4 passes through the pair of lower-end holding means 8, The delivery by the delivery nip roll 12 is temporarily stopped. At the time of this stop, the clamp mechanism 8a of the pair of lower end holding means 8 is closed, and the both ends in the width direction at the lower end portion of the belt-like sheet base material 4 are sandwiched and held. At this time, the clamp mechanism 7a of the pair of upper end holding means 7 is still open.

このような状態から、一対の下端保持手段８が、ピニオン８ｃの回転駆動により支持部材１４の表面部に沿って下動すると共に、これに同期して送出ニップロール１２も回転駆動し、これにより、図６に示すように、帯状シート元材４がさらに下方に送り出され、その送り出し量が所定量に達した時点で、再びその送り出しを一時的に停止させる。この停止時に、一対の上端保持手段７のクランプ機構７ａが閉状態となって、帯状シート元材４の幅方向両側端を挟持して保持する。これにより、帯状シート元材４の幅方向両側端は、下端部が一対の下端保持手段８により保持されると共に、これらの保持部から上方に所定量離間した部位が一対の上端保持手段７により保持される。   From such a state, the pair of lower end holding means 8 is moved down along the surface portion of the support member 14 by the rotational drive of the pinion 8c, and the delivery nip roll 12 is also rotationally driven in synchronization with this, As shown in FIG. 6, when the belt-like sheet base material 4 is further fed downward, and the amount of feeding reaches a predetermined amount, the feeding is temporarily stopped again. At the time of this stop, the clamp mechanism 7a of the pair of upper end holding means 7 is closed, and the both ends in the width direction of the belt-like sheet base material 4 are sandwiched and held. As a result, both ends in the width direction of the belt-like sheet base material 4 are held at the lower end portions by the pair of lower end holding means 8, and the portions spaced apart from these holding portions by a predetermined amount by the pair of upper end holding means 7. Retained.

このような状態の下で、図７に示すように、帯状シート元材４が、一対の上端保持手段７の直上方位置で切断手段６により幅方向全長に亘って切断され、この結果、切断後における所定の大きさのシート材３の四隅が、各保持手段７、８により保持された状態となる。この後においては、各保持手段７、８がシート材３を保持した状態で下動していくが、その下動の途中で、シート材３に上下方向の張力と幅方向の張力とが同時に付与される。   Under such a state, as shown in FIG. 7, the strip-shaped sheet base material 4 is cut over the entire length in the width direction by the cutting means 6 at a position immediately above the pair of upper end holding means 7, and as a result, the cutting is performed. Later, the four corners of the sheet material 3 having a predetermined size are held by the holding means 7 and 8. Thereafter, the holding means 7 and 8 are moved downward while holding the sheet material 3. During the downward movement, the vertical tension and the horizontal tension are simultaneously applied to the sheet material 3. Is granted.

すなわち、一対の下端保持手段８の各ピニオン８ｃをそれぞれ回転駆動させる各モータ８ｂの回転速度は、一対の上端保持手段７の各ピニオン７ｃをそれぞれ回転駆動させる各モータ７ｂの回転速度よりも高速である。そのため、一対の下端保持手段８の下方への移動量の方が、一対の上端保持手段７の下方への移動量よりも多くなり、その結果として、シート材３には上下方向の張力が付与される。更に、一対の下端保持手段８の各ボールねじ機構８ｇの駆動源である各モータ８ｅがそれぞれ回転することに伴って、一方の下端保持手段８のクランプ機構８ａと他方の下端保持手段８のクランプ機構８ａとが幅方向に相離反するように移動する。これと同時に、一対の上端保持手段７の各ボールねじ機構７ｇの駆動源である各モータ８ｅもそれぞれ回転することに伴って、一方の上端保持手段７のクランプ機構７ａと他方の上端保持手段７のクランプ機構７ａとが幅方向に相離反するように移動する。その結果として、シート材３には、幅方向の張力が付与される。   That is, the rotation speed of each motor 8b that rotates and drives each pinion 8c of the pair of lower end holding means 8 is higher than the rotation speed of each motor 7b that rotates and drives each pinion 7c of the pair of upper end holding means 7 respectively. is there. Therefore, the amount of downward movement of the pair of lower end holding means 8 is larger than the amount of downward movement of the pair of upper end holding means 7, and as a result, the sheet material 3 is given vertical tension. Is done. Further, as each motor 8e that is a driving source of each ball screw mechanism 8g of the pair of lower end holding means 8 rotates, the clamp mechanism 8a of one lower end holding means 8 and the clamp of the other lower end holding means 8 are rotated. The mechanism 8a moves so as to be separated from each other in the width direction. At the same time, as each motor 8e that is a drive source of each ball screw mechanism 7g of the pair of upper end holding means 7 rotates, the clamp mechanism 7a of one upper end holding means 7 and the other upper end holding means 7 are rotated. The clamp mechanism 7a moves so as to be separated from each other in the width direction. As a result, a tension in the width direction is applied to the sheet material 3.

そして、このようにシート材３に上下方向及び幅方向の双方の張力が付与された状態を維持して、各保持手段７、８が下動端に達した時点で、各保持手段７、８が停止する。この時点では、支持部材１４が前後方向の適所に移動して停止しているため、各保持手段７、８により保持されているシート材３は、パレット１３上で積層されつつあるガラス板積層体２０の最表面側に存するガラス板２の表面に接触もしくは略接触した状態となるように配置される。この場合、シート材３を下方に移動させる際には、ガラス板２の表面とシート材３とが接触しないようにして、ガラス板２の表面に汚れや傷が付くことを防止し、シート材３が下動端に達した後に、支持部材１４を積層方向に移動させて、シート材３をガラス板２の表面に接触させることにより、両者２、３間の空気を抜くことが行われる。そして、この状態の下で、ガラス板搬送手段（図示略）によって、シート材３の表面側に後続のガラス板２が配置（積層）され、そのガラス板２の自重によりシート材３が押え付けられた時点で、各保持手段７、８のクランプ機構７ａ、８ａが開状態となる。   Then, the state in which the tension in both the vertical direction and the width direction is applied to the sheet material 3 in this way is maintained, and when each holding means 7, 8 reaches the lower end, each holding means 7, 8 Stops. At this time, since the support member 14 has moved to an appropriate position in the front-rear direction and stopped, the sheet material 3 held by the holding means 7, 8 is laminated on the pallet 13. It arrange | positions so that it may be in the state which contacted or substantially contacted the surface of the glass plate 2 which exists in 20 outermost surface side. In this case, when the sheet material 3 is moved downward, the surface of the glass plate 2 and the sheet material 3 are not brought into contact with each other to prevent the surface of the glass plate 2 from being stained or scratched. After 3 reaches the lower end, the support member 14 is moved in the stacking direction, and the sheet material 3 is brought into contact with the surface of the glass plate 2, whereby the air between the two and 3 is removed. Under this state, the subsequent glass plate 2 is arranged (laminated) on the surface side of the sheet material 3 by a glass plate conveying means (not shown), and the sheet material 3 is pressed by the weight of the glass plate 2. At that time, the clamp mechanisms 7a and 8a of the holding means 7 and 8 are opened.

この後においては、一対の上端保持手段７が相接近移動すると共に、一対の下端保持手段８も相接近移動し、且つ、各保持手段７、８が上動することにより、各保持手段７、８は、図４に示す当初の幅方向位置及び当初の上下方向位置に復帰する。そして、この後は、図４〜図７に基づいて説明した態様と同様の動作が繰り返し行われ、パレット１３上に所定枚数のガラス板２とシート材３とが積層された時点で、一つのパレット１３に対するガラス板積層作業が終了する。なお、帯状シート元材４が送出ニップロール１２及び各保持手段７、８により下方に送り出された送り量分は、元材ロール５から帯状シート元材４が引出ニップロール９により引き出される。   Thereafter, the pair of upper end holding means 7 moves closer to each other, the pair of lower end holding means 8 also moves closer to each other, and each holding means 7, 8 moves upward, whereby each holding means 7, 8 returns to the initial position in the width direction and the initial position in the vertical direction shown in FIG. Thereafter, the same operation as that described with reference to FIGS. 4 to 7 is repeatedly performed, and when the predetermined number of glass plates 2 and the sheet material 3 are laminated on the pallet 13, one operation is performed. The glass plate lamination operation on the pallet 13 is completed. The belt-shaped sheet base material 4 is pulled out from the base material roll 5 by the pull-out nip roll 9 for the feed amount of the belt-shaped sheet base material 4 fed downward by the feed nip roll 12 and the holding means 7 and 8.
