Description

【０００１】
【発明の属する技術分野】
本発明は、ガラス板の主表面の周辺などにプライマ液を塗布するガラス板用プライマ液塗布装置に関する。
【０００２】
【従来の技術】
自動車用窓ガラスのなかにはガラス板の周辺に樹脂モールを備えたものがある。この樹脂モールは射出成形によってガラス板の周辺に形成されるが、ガラス板の表面に樹脂モールを直接形成すると、ガラス板の表面に樹脂モールを良好に付着させることは難しい。
【０００３】
そこで、樹脂モールを射出成形する前に、ガラス板の周辺に接着剤を塗布（以下、「プライマ処理」という）し、この接着剤の表面に樹脂モールを射出成形することで、ガラス板の表面に樹脂モールを接着剤で良好に付着させている。
【０００４】
プライマ処理を施す例として自動車用窓ガラスについて説明したが、このプライマ処理は、自動車用窓ガラスに限ることなく、太陽電池用ガラス板などにも適用されている。
このようなプライマ処理を施す装置として、例えば特開平１１−３４７４７０号公報「塗布装置」が知られている。この技術を図１０に基づいて説明する。
【０００５】
図１０（ａ），（ｂ）は従来のガラス板用プライマ塗布方法を説明する説明図である。
（ａ）は、ガラス板１００の対向する二辺１０１，１０２に一定の塗布幅Ｗ１でプライマ液を塗布し、その他の二辺１０３，１０４に一定の塗布幅Ｗ２でプライマ液を塗布した状態を示す。
（ｂ）に示すプライマ液塗布装置１０５は、本体１０６の裏面を案内板１０７で２面に仕切り、一方の裏面に第１塗布部材１０８（塗布幅Ｗ１）を設けるとともに、他方の裏面に第２塗布部材１０９（塗布幅Ｗ２）を設けたものである。
【０００６】
このプライマ液塗布装置１０５によれば、ガラス板１００の周辺に第２塗布部材１０９を接触させるとともに、ガラス板１００の端面１００ａに案内板１０７を当て、この状態で、第２塗布部材１０９に第２液供給管１１１からプライマ液を供給しながら、プライマ液塗布装置１０５をガラス板１００の周辺に沿って移動することにより、ガラス板１００の周辺に塗布幅Ｗ２でプライマ液を塗布することができる。
【０００７】
一方、ガラス板１００の周辺に第１塗布部材１０８を接触させるとともに、ガラス板１００の端面１００ａに案内板を当て、この状態で、第１塗布部材１０８に第１液供給管１１０からプライマ液を供給しながら、プライマ液塗布装置１０５をロボットなどでガラス板１００の周辺に沿って移動することにより、ガラス板１００の周辺に塗布幅Ｗ１でプライマ液を塗布することができる。
【０００８】
【発明が解決しようとする課題】
ここで、ガラス板１００のなかにはガラス板の各辺毎や辺内において、プライマ処理の塗布幅を変えたい場合がある。この内容を図１１で説明する。
図１１は従来のガラス板にプライマ処理を施した状態を示す平面図である。
ガラス板１００は、左辺１００ａの塗布幅をＷ３、右辺１００ｂの塗布幅をＷ４、上辺１００ｃの塗布幅をＷ５とし、下辺１００ｄの塗布幅をＷ６、Ｗ７の２種類の幅にしたものである。
なお、ガラス板のなかには左辺などの一辺のみで塗布幅を変えたい場合もある。
【０００９】
このように、ガラス板１００の塗布幅を各辺毎に異ならせる場合や、下辺１００ｄ内で塗布幅をＷ６、Ｗ７に変えたい場合には、従来のプライマ液塗布装置１０５で対応することはできない。
このため、ガラス板１００の塗布幅を各辺毎に異ならせることができ、かつ一辺内のみでも塗布幅を異ならせることができるように、プライマ液の塗布幅を任意に変更することができるプライマ液塗布装置の実用化が望まれていた。
【００１０】
また、プライマ液塗布装置１０５をロボットで移動する場合には、プライマ液塗布装置１０５の移動軌跡をティーチングで予め決めておき、ティーチングで決めた移動軌跡にしたがってプライマ液塗布装置１０５を移動することで、ガラス板１００の周辺に沿ってプライマ液を塗布する。
【００１１】
このように、プライマ液塗布装置１０５をロボットで移動する場合には、例えばガラス板１００の製造誤差でガラス板１００の塗布面がずれると、正規の塗布面からずれてプライマ液を塗布する虞がある。
このため、プライマ液を正規の塗布面に確実に塗布することができる塗布精度の高いプライマ液塗布装置の実用化が望まれていた。
【００１２】
そこで、本発明の目的は、プライマ液の塗布幅を任意に変更することができ、かつプライマ液を正規の塗布面に確実に塗布することができる塗布精度の高いガラス板用プライマ液塗布装置を提供することにある。
【００１３】
【課題を解決するための手段】
上記目的を達成するために本発明の請求項１は、ガラス板の主表面端部にプライマ液を塗る液塗布部材と、ガラス板の端面に当てる端面当接部材と、液塗布部材に端面当接部材が直角をなすように両部材を支える保持部材と、端面当接部材の位置を変更するために保持部材に備えたシリンダユニットと、からなり、シリンダユニットで端面当接部材の位置を変更することで液塗布部材による塗布幅を変更することができることを特徴とする。
【００１４】
シリンダユニットで端面当接部材の位置を変えることで液塗布部材による塗布幅を任意に変更することができるので、一枚のガラス板の塗布中に、ガラス板の各辺毎や、一辺内において塗布幅を任意に変更することもできる。
【００１５】
請求項２は、液塗布部材及び端面当接部材をガラス板の端面に対して直交させて移動可能に支えるとともに、端面当接部材をガラス板の端面に押し付ける第１付勢手段を備え、かつ、液塗布部材及び端面当接部材をガラス板の主表面端部に対して略直交させて移動可能に支えるとともに、液塗布部材をガラス板の主表面端部に押し付ける第２付勢手段を備えたことを特徴とする。
【００１６】
液塗布部材及び端面当接部材をガラス板の端面に対して直交させて移動可能に支えるとともに、両部材をガラス板の端面に押し付ける第１付勢手段を備えた。よって、例えばガラス板の製造誤差でガラス板の端面にずれが生じても、端面当接部材をガラス板の端面に好適に押し付けた状態で追従させることができる。
【００１７】
また、液塗布部材及び端面当接部材をガラス板の主表面端部に対して略直交させて移動可能に支えるとともに、液塗布部材をガラス板の主表面端部に押し付ける第２付勢手段を備えた。よって、例えばガラス板の製造誤差でガラス板の主表面端部にずれが生じても、液塗布部材をガラス板の主表面端部に好適に押し付けた状態で追従させることができる。
【００１８】
【発明の実施の形態】
本発明の実施の形態を添付図に基づいて以下に説明する。なお、図面は符号の向きに見るものとする。
図１（ａ），（ｂ）は本発明に係るガラス板用プライマ液塗布装置でプライマ液を塗布した後に樹脂モールを成形した自動車用窓ガラスの斜視図である。
自動車用窓ガラスＧは、ガラス板１０の外面１１の周辺部、すなわち外面周辺部（主表面端部）１２、端面１３及び内面１４の周辺部、すなわち内面周辺部（主表面端部）１５にそれぞれプライマ液１６を塗布した後、これらプライマ液１６を塗布幅Ｗで塗布した塗布面（外面周辺部１２、端面１３及び内面周辺部１５）を覆うように樹脂モール１７を射出成形したものである。
【００１９】
プライマ液１６を塗布した塗布面（外面周辺部１２、端面１３及び内面周辺部１５）に樹脂モール１７を射出成形することで樹脂モール１７をガラス板１０に良好に接合させることができる。
以下、ガラス板１０の外面周辺部１２、端面１３及び内面周辺部１５にそれぞれプライマ液１６を塗布するガラス板用プライマ液塗布装置について説明する。
【００２０】
図２は本発明に係るガラス板用プライマ液塗布装置を示す側面図である。
ガラス板用プライマ液塗布装置２０は、ベース２１にスタンド２２を立て、このスタンド２２の上端２３側に上部塗布機構２５を揺動自在に取り付け、スタンド２２の略中央に下部塗布機構２６を揺動自在に取り付け、上部塗布機構２５でガラス板１０の外面周辺部１２にプライマ液を塗布し、下部塗布機構２６でガラス板１０の端面１３及び内面周辺部１５にプライマ液を塗布する装置である。
【００２１】
上部塗布機構２５は、スタンド２２に支持軸２８を介して揺動自在に取り付けたスイング部材３０と、スイング部材３０に取り付けてスイング部材３０を時計回り方向に付勢する引張りばね（第２付勢手段）３１と、スイング部材３０にガラス板１０の塗布面（外面周辺部）１２に近づく方向と離れる方向に移動自在に設けた保持部材３２と、保持部材３２に取り付けた液塗布部材３３及び端面当接部材３４と、端面当接部材３４の位置を変更するシリンダユニット３５とを備える。
なお、ガラス板１０は、ロボット１８の吸着パッド１９で吸着することでプライマ液塗布位置に位置決めされる。
【００２２】
図３は本発明に係るガラス板用プライマ液塗布装置の上部塗布機構を示す分解斜視図である。
スタンド２２の上端２３に支持部材３７を取り付け、支持部材３７の先端３８に引張りばね３１の上端３１ａをピン３９を介して掛け、引張りばね３１の下端３１ｂをピン４１を介してスイング部材３０の後端３０ａに掛ける。
これにより、引張りばね３１でスイング部材３０を支持軸２８を軸にして時計回り方向に付勢することができる。
【００２３】
スイング部材３０の前端３０ｂにシャフト４２を介して保持プレート４３を取り付け、保持プレート４３の両端に連結部４４，４４を備える。
連結部４４，４４にねじ孔４５，４５を備える。ねじ孔４５，４５には連結ロッド４６，４６の先端ねじ部４７，４７をねじ結合することができる。
【００２４】
一対の連結ロッド４６，４６には保持部材３２のスライドプレート５０をスライド自在に取り付けている。スライドプレート５０の上端には支え片５１の基端５２をボルト５３・・・で固定し、支え片５１の先端５４には液塗布部材３３をボルト５６，５６で固定する。
なお、支え片５１の基端５２には一対の貫通孔５２ａ，５２ａ（図４に手前側のみを示す）を設ける。
【００２５】
スライドプレート５０は、略Ｔ形に形成したプレートで、支え片５１の貫通孔５２ａ，５２ａに同軸に貫通孔５０ａ，５０ａ（図４に手前側のみを示す）を開けるとともに、貫通孔５０ａ，５０ａに同軸上に軸受部５７，５７を取り付け、下端には第１、第２の貫通孔５０ｂ，５０ｃ（図４に示す）を開け、第１貫通孔５０ｂに同軸上に軸受部５８を取り付けるた部材である。
【００２６】
貫通孔５２ａ，５２ａ、貫通孔５０ａ，５０ａ及び軸受部５７，５７に連結ロッド４６，４６を差し込み、連結ロッド４６，４６の後端フランジ部４８，４８と軸受部５７，５７との間に圧縮ばね（第１付勢手段）５９，５９を配置する。加えて、連結ロッド４６，４６の先端ねじ部４７，４７を連結部４４，４４のねじ孔４５，４５にねじ結合することにより、保持部材３２を連結ロッド４６，４６に対してスライド自在に支えるとともに、保持部材３２を圧縮ばね５９で矢印Ａ方向に付勢することができる。
【００２７】
一方、第１貫通孔５０ｂ及び軸受部５８にスライドロッド６０をスライド自在に取り付け、スライドロッド６０の先端６０ａにプレート６２を取り付け、プレート６２に端面当接部材３４をボルト６３・・・（図５に示す）で固定する。
また、第２貫通孔５０ｃに同軸上にシリンダユニット３５をボルト６１，６１（図４に示す）で取り付け、シリンダユニット３５のピストンロッド３６を第２貫通孔５０ｃを貫通させ、ピストンロッド３６の先端３６ａをプレート６２に取り付ける。
【００２８】
図４は、本発明に係るガラス板用プライマ液塗布装置の上部塗布機構を示す側面図であり、ガラス板１０の外面周辺部１２に液塗布部材３３を当てるとともに、ガラス板１０の端面１３（図３に示す）に端面当接部材３４を当て、液塗布部材３３に端面当接部材３４が直角をなすように両部材を保持部材３２で支え、端面当接部材３４の位置を変更するために、保持部材３２にシリンダユニット３５を備えた状態を示す。
シリンダユニット３５で端面当接部材３４の位置を矢印Ｂ方向に変更することで、液塗布部材３８による塗布幅Ｗを任意に変更することができる。
【００２９】
このように、ガラス板用プライマ液塗布装置２０は塗布幅Ｗをシリンダユニット３５で任意に変更可能に構成したので、シリンダユニット３５のピストンロッド３６の移動量を調整することで、塗布幅を任意に変更することができる。
このため、従来技術で説明したように、塗布幅が２通りに限定されることがない。
【００３０】
なお、本実施形態においては、塗布幅Ｗを調整するシリンダユニット３５としては、図示しないすべりねじをステッピングモータで駆動して位置制御をおこなう電動シリンダが該当するが、塗布幅Ｗを調整する手段はシリンダユニット３５に限るものではなく、ボールねじなどのその他の手段を使用することも可能である。要は、塗布幅Ｗを任意に調整できるものであればよい。
【００３１】
また、この図は、スイング部材３０にシャフト４２及び保持プレート４３を介して連結ロッド４６，４６を取り付け、連結ロッド４６，４６に保持部材３２のスライドプレート５０をスライド自在に取り付け、圧縮ばね５９，５９を連結ロッド４６，４６の後端フランジ部４８，４８と軸受部５７，５７との間に備えた状態を示す。
【００３２】
これにより、圧縮ばね５９，５９により、液塗布部材３３及び端面当接部材３４をガラス板１０の端面１３に対して直交させて移動可能に支えるとともに、両部材３３，３４をガラス板１０の端面１３に押し付けることができる。
すなわち、保持部材３２をガラス板１０の塗布面（外面周辺部）１２に近づく方向と離れる方向とに移動自在に支えることができ、この保持部材３２を圧縮ばね５９，５９で塗布面（外面周辺部）１２に近づく方向に付勢することにより端面当接部材３４をガラス板１０の端面１３に押し付けることができる。
よって、例えばガラス板１０の製造誤差でガラス板１０の端面１３にずれが生じても、端面当接部材３４をガラス板１０の端面１３に好適に押し付けた状態で追従させることができる。
【００３３】
さらに、この図は、スタンド２２に支持軸２８を介してスイング部材３０を揺動自在に取り付け、スタンド２２の上端２３に支持部材３７を取り付け、支持部材３７の先端３８にピン３９を介して引張りばね３１の上端３１ａを掛け、引張りばね（第２付勢手段）３１の下端３１ｂをピン４１を介してスイング部材３０の後端３０ａに掛けた状態を示す。
【００３４】
これにより、引張りばね３１により、液塗布部材３３及び端面当接部材３４をガラス板１０の外面周辺部１２に対して略直交させて移動可能に支えるとともに、液塗布部材３３をガラス板１０の外面周辺部１２に押し付けることができる。
【００３５】
そして、例えば、ガラス板１０の製造誤差でガラス板１０の外面周辺部１２が上方や下方にずれた場合には、スイング部材３０が時計回り方向や反時計回り方向に揺動することにより、液塗布部材３３をガラス板１０の外面周辺部１２に良好に押し付けることができる。
なお、スイング部材３０の時計回り方向の揺動量は第１ストッパボルト６４で規制し、反時計回り方向の揺動量は第２ストッパボルト６５で規制することができる。
【００３６】
図５は、本発明に係るガラス板用プライマ液塗布装置の液塗布部材、及び端面当接部材を示す斜視図である。
液塗布部材３３は、上端６６を支え片５１の先端５４にボルト５６，５６で固定し、下端６７の幅を上端６６の幅より狭く形成し、下端６７に開口部６８を形成し、この開口部６８に連通した収納部６９を備え、この収納部６９にフェルトなどの液吸込部材７０を収納し、液吸込部材７０の底面７１を下端６７から僅かに突出させ、この液吸込部材７０の上端側に第１液供給ホース７２を接続するとともに、液吸込部材７０の下端側に第２液供給ホース７３を接続したものである。
第１、第２の液供給ホース７２，７３からプライマ液を供給することで、液吸込部材７０にプライマ液を染み込ませることができる。
【００３７】
端面当接部材３４は、略直方体のブロックであり、３個のボルト６３・・・でプレート６２に固定したものである。端面当接部材３４の前面７５にはガラス板１０の端面１３が当接する突起７６を備える。
突起７６の表面を湾曲状に形成することで、図４に示すガラス板１０の端面１３を円滑に移動することができる。
【００３８】
この突起７６にガラス板１０の端面１３を当接するとともに、ガラス板１０の外面周辺部１２（図４に示す）を液吸込部材７０の底面７１に押し付けながら、ガラス板１０を移動することにより、ガラス板１０の外面周辺部１２にプライマ液を塗ることができる。
【００３９】
図１に戻って、下部塗布機構２６は、ガラス板１０の端面１３及び内面周辺部１５にプライマ液を塗布するもので、ガラス板１０の端面１３にプライマ液を塗布するように構成した点で上部塗布機構２５と異なるだけで、その他の構成は上部塗布機構２５と同じである。
【００４０】
ガラス板１０の端面１３にプライマ液を塗布するために、端面当接部材７７に液吸込部材（図示しない）を備え、この液吸込部材に液供給ホース７８を接続する。
液供給ホース７８からプライマ液を供給し、液吸込部材にプライマ液を染み込ませることで、ガラス板１０の端面１３にプライマ液を塗布することができる。よって、下部塗布機構２６において、上部塗布機構２５と同一構成については同一符号を付して説明を省略する。
【００４１】
次に、ガラス板用プライマ液塗布装置の作用を、図６〜図９に基づいて説明する。
図６（ａ），（ｂ）は、本発明に係るガラス板用プライマ液塗布装置の作用を説明する第１作用説明図である。
（ａ）において、ガラス板１０をロボット１８の吸着パッド１９（図１に示す）で保持し、ガラス板１０の端面１３を端面当接部材３４の突起７６に当てるとともに、ガラス板１０の外面周辺部１２を液塗布部材３３を当てる。
【００４２】
この状態で、ロボット１８を作動させることにより、ガラス板１０を突起７６に当てるとともに液塗布部材３３を当てながら移動する。
これにより、ガラス板１０の外面周辺部１２に液塗布部材３３の液吸込部材でプライマ液を塗布することができる。
【００４３】
ここで、このプライマ液の塗布中に、ガラス板１０の製造誤差によりガラス板１０の外面周辺部１２が上方にずれた場合には、ガラス板１０の外面周辺部１２で液塗布部材３３を上方に持ち上げようとする力が矢印の如く働く。
【００４４】
（ｂ）において、ガラス板１０の外面周辺部１２による上方への持上力が、液塗布部材３３から支え片５１、スライドプレート５０、支持プレート４３、シャフト４２を介してスイング部材３０の前端３０ｂに伝わる。
よって、スイング部材３０が引張りばね３１の付勢力に抗して支持軸２８を軸にして反時計回り方向にスイングする。
【００４５】
これにより、液塗布部材３３をガラス板１０の外面周辺部１２に追従させて上方に逃がすことができる。したがって、液塗布部材３３をガラス板１０の外面周辺部１２に良好に押し付けた状態を保つことができ、プライマ液を正規の塗布面に確実に塗布することができる。
【００４６】
図７（ａ），（ｂ）は、本発明に係るガラス板用プライマ液塗布装置の作用を説明する第２作用説明図である。
（ａ）において、ガラス板１０の製造誤差によりガラス板１０の外面周辺部１２が下方にずれた場合には、ガラス板１０の外面周辺部１２が下方に矢印の如く下降する。
このため、ガラス板１０の外面周辺部１２が液塗布部材３３から離れようとする。
【００４７】
（ｂ）において、ガラス板１０の外面周辺部１２が液塗布部材３３から離れようとすることで、ガラス板１０の外面周辺部１２による液塗布部材３３の保持力が減少する。
スイング部材３０の前端３０ｂを保持する力が減少することにより、スイング部材３０が引張りばね３１の付勢力で支持軸２８を軸にして時計回り方向にスイングする。
【００４８】
これにより、液塗布部材３３をガラス板１０の外面周辺部１２に追従させて下方に移動することができる。よって、液塗布部材３３をガラス板１０の外面周辺部１２に良好に押し付けた状態を保つことができ、プライマ液を正規の塗布面に確実に塗布することができる。
【００４９】
図８（ａ），（ｂ）は、本発明に係るガラス板用プライマ液塗布装置の作用を説明する第３作用説明図である。
（ａ）において、ガラス板１０を端面当接部材３４の突起７６に当てるとともに液塗布部材３３を当てながら移動することで、ガラス板１０の外面周辺部１２に液塗布部材３３の液吸込部材でプライマ液を塗布する。
このとき、液塗布部材３３はＰ１に位置する。
【００５０】
ガラス板１０の製造誤差により、ガラス板１０の端面１３がスタンド２２に向けて張り出した場合には、ガラス板１０の端面１３を端面当接部材３４の突起７６に矢印の如く押し付けようとする力が働く。
端面当接部材３４の突起７６にかかる押付力が、プレート６２、シリンダユニット３５、スライドプレート５０から圧縮ばね５９に伝わる。よって、スライドプレート５０が圧縮ばね５９の付勢力に抗して矢印の如く移動する。
【００５１】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a primer liquid applying apparatus for a glass plate, which applies a primer liquid around a main surface of a glass plate.
[0002]
[Prior art]
Some automotive window glasses have a resin molding around a glass plate. This resin molding is formed around the glass plate by injection molding. However, if the resin molding is directly formed on the surface of the glass plate, it is difficult to make the resin molding adhere to the surface of the glass plate in a good condition.
[0003]
Therefore, before the resin molding is injection-molded, an adhesive is applied to the periphery of the glass plate (hereinafter, referred to as “primer treatment”), and the resin molding is injection-molded on the surface of the adhesive, thereby obtaining the surface of the glass plate. The resin molding is adhered well with an adhesive.
[0004]
Although the description has been made on the window glass for an automobile as an example of performing the primer treatment, the primer treatment is applied not only to the window glass for an automobile but also to a glass plate for a solar cell and the like.
As an apparatus for performing such a primer treatment, for example, Japanese Patent Application Laid-Open No. H11-347470 discloses a “coating apparatus”. This technique will be described with reference to FIG.
[0005]
FIGS. 10A and 10B are explanatory views illustrating a conventional method of applying a primer for a glass plate.
(A) shows a state in which the primer liquid is applied to two opposing sides 101 and 102 of the glass plate 100 with a constant application width W1 and the other two sides 103 and 104 are applied with the primer liquid with a constant application width W2. Show.
In the primer liquid application device 105 shown in FIG. 2B, the back surface of the main body 106 is divided into two surfaces by a guide plate 107, and a first application member 108 (application width W1) is provided on one back surface, and a second surface is provided on the other back surface. An application member 109 (application width W2) is provided.
[0006]
According to the primer liquid coating device 105, the second coating member 109 is brought into contact with the periphery of the glass plate 100, and the guide plate 107 is brought into contact with the end surface 100 a of the glass plate 100. By moving the primer liquid application device 105 along the periphery of the glass plate 100 while supplying the primer liquid from the two-liquid supply pipe 111, the primer liquid can be applied with a coating width W2 around the glass plate 100. .
[0007]
On the other hand, the first coating member 108 is brought into contact with the periphery of the glass plate 100, and a guide plate is applied to the end surface 100a of the glass plate 100. In this state, the primer liquid is supplied to the first coating member 108 from the first liquid supply pipe 110. By moving the primer liquid application device 105 along the periphery of the glass plate 100 with a robot or the like while supplying, the primer liquid can be applied to the periphery of the glass plate 100 with an application width W1.
[0008]
[Problems to be solved by the invention]
Here, in the glass plate 100, there are cases where it is desired to change the application width of the primer treatment on each side or within each side of the glass plate. This will be described with reference to FIG.
FIG. 11 is a plan view showing a state where a conventional glass plate is subjected to a primer treatment.
In the glass plate 100, the application width of the left side 100a is W3, the application width of the right side 100b is W4, the application width of the upper side 100c is W5, and the application width of the lower side 100d is W2 and W7.
In some cases, it is desired to change the coating width only on one side such as the left side of the glass plate.
[0009]
As described above, when the coating width of the glass plate 100 is made different for each side or when it is desired to change the coating width to W6 or W7 within the lower side 100d, the conventional primer liquid coating apparatus 105 cannot cope with the case. .
For this reason, the primer width in which the coating width of the primer liquid can be arbitrarily changed so that the coating width of the glass plate 100 can be varied for each side, and the coating width can be varied even within only one side. Practical application of the liquid coating device has been desired.
[0010]
When the primer liquid application device 105 is moved by a robot, the movement trajectory of the primer liquid application device 105 is determined in advance by teaching, and the primer liquid application device 105 is moved according to the movement trajectory determined by teaching. Then, a primer liquid is applied along the periphery of the glass plate 100.
[0011]
As described above, when the primer liquid application device 105 is moved by a robot, if the application surface of the glass plate 100 shifts due to, for example, a manufacturing error of the glass plate 100, there is a possibility that the primer liquid is applied by shifting from the regular application surface. is there.
For this reason, there has been a demand for a practical application of a primer liquid coating apparatus having a high coating accuracy that can reliably apply the primer liquid to a regular coating surface.
[0012]
Accordingly, an object of the present invention is to provide a primer liquid applying apparatus for a glass plate with a high coating accuracy that can arbitrarily change the application width of the primer liquid and can surely apply the primer liquid to a regular application surface. To provide.
[0013]

[0014]
By changing the position of the end face contact member with the cylinder unit, the application width by the liquid application member can be arbitrarily changed, so during application of one glass plate, each side of the glass plate, or within one side The application width can be arbitrarily changed.
[0015]
Claim 2 is provided with a first urging means for movably supporting the liquid application member and the end surface contact member perpendicular to the end surface of the glass plate and pressing the end surface contact member against the end surface of the glass plate, and A second urging means for movably supporting the liquid application member and the end surface contact member substantially orthogonal to the main surface end of the glass plate and pressing the liquid application member against the main surface end of the glass plate. It is characterized by having.
[0016]
A first urging means is provided for supporting the liquid application member and the end face contact member so as to be movable perpendicularly to the end face of the glass sheet, and pressing both members against the end face of the glass sheet. Therefore, even if the end face of the glass sheet is shifted due to, for example, a manufacturing error of the glass sheet, the end face contact member can follow the end face of the glass sheet in a state where it is suitably pressed.
[0017]
Further, a second urging means for movably supporting the liquid application member and the end surface abutting member substantially orthogonal to the main surface end of the glass plate and pressing the liquid application member against the main surface end of the glass plate is provided. Equipped. Therefore, even if the main surface edge of the glass plate is displaced due to, for example, a manufacturing error of the glass plate, the liquid application member can be made to appropriately follow the main surface edge of the glass plate while following the same.

The force trying to lift works like an arrow.
[0044]
In (b), the upward lifting force of the outer peripheral portion 12 of the glass plate 10 is applied to the front end 30 b of the swing member 30 from the liquid application member 33 via the support piece 51, the slide plate 50, the support plate 43, and the shaft 42. It is transmitted to.
Therefore, the swing member 30 swings counterclockwise around the support shaft 28 against the urging force of the extension spring 31.
[0045]
This allows the liquid application member 33 to follow the outer peripheral portion 12 of the glass plate 10 and escape upward. Therefore, it is possible to keep the state in which the liquid application member 33 is pressed properly against the outer peripheral portion 12 of the glass plate 10, and it is possible to apply the primer liquid to the regular application surface without fail.
[0046]
FIGS. 7A and 7B are second operation explanatory views for explaining the operation of the glass plate primer liquid applying apparatus according to the present invention.
In (a), when the outer peripheral portion 12 of the glass plate 10 shifts downward due to a manufacturing error of the glass plate 10, the outer peripheral portion 12 of the glass plate 10 descends as indicated by an arrow.
Therefore, the outer peripheral portion 12 of the glass plate 10 tends to separate from the liquid application member 33.
[0047]
In (b), by holding the outer peripheral portion 12 of the glass plate 10 away from the liquid application member 33, the holding force of the liquid application member 33 by the outer peripheral portion 12 of the glass plate 10 decreases.
As the force for holding the front end 30b of the swing member 30 decreases, the swing member 30 swings clockwise about the support shaft 28 by the urging force of the tension spring 31.
[0048]
Thereby, the liquid application member 33 can be moved downward while following the outer peripheral portion 12 of the glass plate 10. Therefore, it is possible to maintain a state in which the liquid application member 33 is satisfactorily pressed against the outer peripheral portion 12 of the glass plate 10, and it is possible to reliably apply the primer liquid to the regular application surface.
[0049]
FIGS. 8A and 8B are third operation explanatory views illustrating the operation of the glass plate primer liquid applying apparatus according to the present invention.
In (a), by moving the glass plate 10 against the protrusions 76 of the end surface contact member 34 and moving the glass plate 10 while applying the liquid application member 33, the outer peripheral portion 12 of the glass plate 10 is moved by the liquid suction member of the liquid application member 33. Apply primer solution.
At this time, the liquid application member 33 is located at P1.
[0050]
When the end surface 13 of the glass plate 10 protrudes toward the stand 22 due to a manufacturing error of the glass plate 10, a force for pressing the end surface 13 of the glass plate 10 against the protrusion 76 of the end surface contact member 34 as indicated by an arrow. Works.
The pressing force applied to the projection 76 of the end face contact member 34 is transmitted from the plate 62, the cylinder unit 35, and the slide plate 50 to the compression spring 59. Therefore, the slide plate 50 moves as shown by the arrow against the urging force of the compression spring 59.
[0051]
In (b), the slide plate 50 moves as shown by the arrow against the urging force of the compression spring 59 so that the projection 76 of the end surface contact member 34 follows the end surface 13 of the glass plate 10 and It is possible to escape in a direction away from the end face 13.
At this time, the liquid application member 33 also follows the end surface 13 of the glass plate 10 integrally with the end surface contact member 34, and can escape to the position P2 in a direction away from the end surface 13 of the glass plate 10.
Therefore, it is possible to maintain a state in which the liquid application member 33 is satisfactorily pressed against the outer peripheral portion 12 of the glass plate 10, and it is possible to reliably apply the primer liquid to the regular application surface.
[0052]
On the other hand, when the end surface 13 of the glass plate 10 is shifted in a direction away from the stand 22 due to a manufacturing error of the glass plate 10, the end surface 13 of the glass plate 10 tends to separate from the projection 76 of the end surface contact member 34. Therefore, the holding force of the projection 76 of the end surface contact member 34 by the end surface 13 of the glass plate 10 decreases.
[0053]
Thereby, the projection 76 of the end face contact member 34 can be moved downward by following the end face 13 of the glass plate 10 by the urging force of the compression spring 59.
At this time, the liquid application member 33 can also follow the end surface 13 of the glass plate 10 integrally with the end surface contact member 34 and follow the end surface 13 of the glass plate 10.
Therefore, it is possible to maintain a state in which the liquid applying member 33 is satisfactorily pressed against the outer peripheral portion 12 of the glass plate 10.
[0054]
FIGS. 9A and 9B are fourth operation explanatory views illustrating the operation of the glass plate primer liquid application device according to the present invention.
In (a), by moving the glass plate 10 against the protrusions 76 of the end surface contact member 34 and moving the glass plate 10 while applying the liquid application member 33, the outer peripheral portion 12 of the glass plate 10 is moved by the liquid suction member of the liquid application member 33. Apply primer solution.
[0055]
At this time, by keeping the piston rod 36 of the cylinder unit 35 in a state of being protruded to the maximum as an example, the projection 76 of the end face contact member 34 can be brought closer to the tip 70 a of the liquid suction member 70.
Therefore, the application width W of the outer peripheral portion 12 of the glass plate 10 can be reduced.
[0056]
Then, for example, after one side of the outer surface peripheral portion 12 of the glass plate 10 is applied with a reduced application width W, there is a case where it is desired to apply the application width W on the other side to be wide. In this case, by moving the piston rod 36 of the cylinder unit 35 as shown by the arrow, the end face contact member 34 together with the plate 62 is moved away from the tip 70a of the liquid suction member 70 as shown by the arrow.
[0057]
In (b), the distance from the protrusion 76 of the end surface contact member 34 to the distal end 70a of the liquid suction member 70 is kept large by moving the end surface contact member 34 in a direction away from the tip 70a of the liquid suction member 70. Can be.
Thereby, the application width W of the outer peripheral portion 12 of the glass plate 10 can be increased.
As described above, by changing the position of the end face contact member 34 by the cylinder unit 35, the application width W of the liquid application member 33 can be changed.
[0058]
Further, in the glass plate 10, for example, there is a case where it is desired to change the coating width even within a range of one side such as a left side. However, adopting the glass plate primer liquid coating device 20 can cope with such a case. .
[0059]
Further, in FIG. 9, during the application of one glass plate 10, the application width W is arbitrarily changed for each side of the glass plate 10, or the application width W is changed within one side such as the left side. Although the preferred case has been described as an example, the use of the glass plate primer liquid coating device 20 allows the primer liquid to be applied to various glass plates 10 having different application widths W.
As described above, since one glass plate primer liquid coating apparatus 20 can cope with various glass plates 10 having different coating widths W, the equipment can be simplified.
[0060]
In the above-described embodiment, an example in which the tension spring 31 is used as a means for swinging the swing member 30 has been described. However, the present invention is not limited to this, and a compression spring may be used.
Further, an example has been described in which a compression spring is used to press the projection 76 of the end surface contact member 34 against the end surface 13 of the glass plate 10 suitably. However, the present invention is not limited to this, and a tension spring may be used. .
[0061]
【The invention's effect】
The present invention has the following effects by the above configuration.
According to the first aspect, since the width of application by the liquid application member can be changed by changing the position of the end face contact member by the cylinder unit, the application is performed on each side of the glass plate during application of one glass plate. The width can be arbitrarily changed.
[0062]
According to a second aspect of the present invention, the liquid application member and the end surface contact member are movably supported perpendicular to the end surface of the glass plate, and the first urging means presses both members against the end surface of the glass plate. Therefore, even if the end face of the glass sheet is shifted due to, for example, a manufacturing error of the glass sheet, the end face contact member can follow the end face of the glass sheet in a state where it is suitably pressed.
[0063]
Further, a second urging means for movably supporting the liquid application member and the end surface abutting member substantially orthogonal to the main surface end of the glass plate and pressing the liquid application member against the main surface end of the glass plate is provided. Equipped. Therefore, even if the main surface edge of the glass plate is displaced due to, for example, a manufacturing error of the glass plate, the liquid application member can be made to appropriately follow the main surface edge of the glass plate while following the same.
[0064]
For this reason, even if the end surface of the glass plate or the end of the main surface is displaced due to a manufacturing error of the glass plate, the end surface contact member can always suitably contact the end surface of the glass plate. Therefore, the liquid application member can be accurately brought into contact with the application surface of the glass plate, so that the primer liquid can be reliably applied to the regular application surface.
