Description

【０００１】
【発明の属する技術分野】
本発明は寸法形状の異なる多品種のガラス板を立掛け状態で連続的に洗滌し乾燥させる方法と装置に関する。
【０００２】
【従来の技術】
縦掛け状態で連続的に搬送されるガラス板の洗滌乾燥方法や装置としては、従来より種々のものが開示されている。
【０００３】
例えば、特公昭４９−１６９９０号公報には、ガラス板を縦にして上端部を倒れないように数カ所で案内し、下端部は駆動ロール上に載置して移動させ、その移動中に洗滌液等により洗滌する洗滌工程と、水洗による予備濯ぎ工程と、ガラス板の両面上方より不純物を含まない清浄水をガラス面に沿って流下させる仕上げ濯ぎ工程と、ガラス板の上端面の水滴を除去する工程と、気流乾燥を行う乾燥工程とを順次に行うガラス板の洗滌方法が開示されている。
【０００４】
また、特公昭６３−２１０５号公報には、洗浄に先立ちガラスの表面にポリビニールアルコール水溶液を塗布する工程、該ガラスを熱処理する工程、該ガラスの表面を水を含む液体により摩擦洗浄する工程、該ガラスの表面を乾燥する工程を有するガラスの洗浄方法が開示されている。
【０００５】
さらにガラス板の洗滌方法としては、水洗と同時に回転するブラシロールをガラス板面に押し付けて汚れを洗浄させる方法が良く知られ、洗滌後のガラス面の水切り方法については絞りロール等による方法が一般に良く知られている。
【０００６】
【発明が解決しようとする課題】
特公昭４９−１６９９０号公報のものは、平面ガラスの上辺部をロールで挟持し、下辺部を搬送ロールで支持してガラス板を縦状態で搬送させ洗浄するものであるため、異形状のガラス板や湾曲したガラス板等に適用しようとすることは困難である。
【０００７】
また、特公昭６３−２１０５号公報のものは、ガラスの表面にポリビニールアルコール水溶液を塗布し、熱処理工程で水分を蒸発させるものであるが、実施例によれば１００℃３０分の熱処理とあり、水分の蒸発に時間がかかり、寸法の大きなガラスを多量に処理する場合には処理タクトが遅くなるといった問題点があった。
【０００８】
さらに、ブラシロールを用いる洗滌方法や絞りロールによる水切り乾燥は、ガラスの形状が変化したときに、その都度ガラスの形状に合わせてブラシロールや絞りロールの形状を対応させなければならず、少量多品種のガラス板の洗滌乾燥の場合段取り替えが多く発生し効率が悪くなるという問題点があった。
【０００９】
【課題を解決するための手段】
本発明は、上記問題点、すなわち寸法形状の異なる多品種の湾曲したガラス板を混載状態で連続して搬送、洗滌、かつ乾燥でき、ガラス板面の汚れをクリーンに洗滌でき、乾燥後の水跡も残らないことを目的とするものである。
すなわち、本発明は、トンネル状のチャンバー内を連続的に搬送されるガラス板を洗滌および乾燥させる方法において、コンベアの幅方向の両端付近に一対のペグをコンベア全周にわたって等間隔に立設したペグ式搬送装置のペグ間に、チャンバーの入口側でガラス板を投入移載し、立掛状態にして寸法形状の異なる多品種のガラス板群を搬送し、工業用水による水洗後、温水によるシャワー洗滌を行い、さらに純水でリンスさせ、温風により乾燥し、チャンバーの出口側で取出し、次工程に搬送させることを特徴とするガラス板の洗滌乾燥方法である。
あるいはまた、本発明は、洗滌工程前に予めガラス板の表面に界面活性剤を塗布し汚れを分離させるようにしたことを特徴とする上述のガラス板の洗滌乾燥方法である。
あるいはまた、本発明は、前記連続処理されるガラス板が湾曲ガラス板であることを特徴とする上述のガラス板の洗浄乾燥方法である。
あるいはまた、本発明は、トンネル状のチャンバー内を連続的に搬送されるガラス板を洗滌および乾燥させる装置において、コンベアの幅方向の両端付近に一対の金属製ロッドにポリテトラフルオロエチレン製のチューブを被覆、または貼着したペグをコンベア全周にわたって等間隔に立設したペグ式搬送装置をチャンバー内の入口側から出口側までを貫いて設け、かつ、入口側より工業用水シャワー洗滌ゾーン、温水シャワー洗滌ゾーン、純水によるリンス洗滌ゾーン、上部ヒーターによる温風をガラス板面に噴射させてガラス表面を乾燥させる乾燥ゾーン、冷却ファンによりガラス板を冷却させる冷却ゾーンを設けたことを特徴とする請求項１〜３のいずれかの記載の方法に用いるガラス板の洗滌乾燥装置である。
あるいはまた、本発明は、前記洗浄装置の工業用水のシャワー洗滌ゾーンの上流に界面活性剤の塗布を行う界面活性剤塗布ゾーンを設けたことを特徴とする上述のガラス板の洗滌乾燥装置である。
【００１０】
【発明の実施の形態】
本発明は、寸法形状の異なる多品種のガラス板群を混載状態にして、それぞれペグと称するロッドに立掛け、トンネル状のチャンバー内に設けた洗滌工程、水切り乾燥工程を連続的に搬送通過させ、ガラス板面の洗滌、及び水切り乾燥を行うものである。
【００１１】
上記洗滌工程にガラス板を投入するに先だって、ガラス板面に界面活性剤を塗布し汚れを遊離させるようにした後、洗滌工程にガラス板を搬送させる。 まず、工業用水洗滌ゾーンで立掛け状態で搬送中のガラス板の上部から工業用水をスプレー散水し、ガラス板面に遊離した埃やホコリ等の汚れの大半を洗い落とし、続く温水洗滌ゾーンで、温水によるシャワー洗滌させ、工業用水による洗滌では洗滌除去できなかったガラス板面に残存付着の汚れや界面活性剤を完全に洗い落とし、さらに、純水洗滌ゾーンで、ガラス板面の乾燥後に水跡が残らないように、純水によるリンス洗滌により、ガラス板面に付着の不純物を含む工業用水や温水を洗い流すようにした。
【００１２】
洗滌中は散水部の霧滴が乾燥ゾーンに流出しないように洗滌ゾーンの上部に軸流ファンを設けてドラフトをかけるようにした。 続いて乾燥ゾーンに搬送されたガラス板に対し、上部に設けた加熱ヒーターによる熱を循環式ファンによる温風にてガラス板に噴出し、ガラス板面に残存の水滴を蒸発乾燥させた。
【００１３】
次の冷却ゾーンに搬送されたガラス板は、前工程の乾燥ゾーンで熱を吸収して熱くなっているので冷却ファンで常温まで冷却し、トンネル状のチャンバーを出て次工程に引き継がれる。
【００１４】
前記ペグはＳＵＳ等の金属製ロッドにポリテトラフルオロエチレン製のチューブを全周に被覆、あるいはガラス板と当接する面側にポリテトラフルオロエチレン板を固着させ、前記ガラス板にキズをつけずに立掛け状態で載置させることができる。
【００１５】
このように前記ガラス板をペグに立掛け状にして搬送するので、フラット板、湾曲板、寸法形状が異なるガラス板等をランダムに搬送でき、また前記の洗滌乾燥方法および装置で洗滌、乾燥させたため通常行われている生産品種の変更時等の段取り替えも不要となり、生産性の向上を図ることができるようになった。
【００１６】
【実施例】
以下、本発明に係わるガラス板の洗滌乾燥方法およびその装置の実施例について図面に基づき詳細に説明する。
【００１７】
図１は本発明の実施例を説明するガラス板の洗滌乾燥方法および装置の概略側面図を示し、図２は本発明の実施例を説明するペグ式搬送装置の一部を切欠、省略した斜視図を示し、図３は本発明の別の実施例を説明するガラス板の洗滌乾燥方法および装置の概略側面図を示す。
【００１８】
まず、図２に示すようなペグ式の搬送装置２がある。該ペグ式の搬送装置２はコンベアの幅方向の両端付近に一対のペグ３をコンベア全周にわたって等間隔に立設したものである。
【００１９】
該ペグ３はＳＵＳ等の金属製ロッド４にポリテトラフルオロエチレン製のチューブ５を全周に被覆したもの、あるいは金属製の細長い板材の全周あるいはガラス板１と当接する面側に該ポリテトラフルオロエチレン製の板を固着させたものであり、これはペグ３に立掛け載置したガラス板１にキズ等をつけないように保護するものであるが、乾燥ゾーン１６で温風を噴射するため耐熱性樹脂であるポリテトラフルオロエチレンを用いた。
【００２０】
また、ペグ３は洗滌機内で水に晒されるためステンレス等の錆びない金属とし、錆によるガラス板１の面への汚れの発生を防止するようにした。 ガラス板１は前記ペグ３間に立掛状態にして搬送されるが、寸法形状の異なる多品種のガラス板１であっても混載状態にして搬送することができる。
【００２１】
つぎに、図１に示すようなトンネル状のチャンバー２２内の入口側１０から出口側２１までを貫いて前記ペグ式の搬送装置２が設けられ、チャンバー２２の入口側１０でガラス板１を投入移載し、出口側２１で取出し次工程に搬送させるものである。
【００２２】
該チャンバー２２内は入口側１０側より工業用水洗滌ゾーン１３、温水洗滌ゾーン１４、純水洗滌ゾーン１５、乾燥ゾーン１６、冷却ゾーン１９からなり、ガラス板１はペグ３に立掛け状態で前記各工程を連続的に搬送通過し、ガラス板１の洗滌、及び水切り乾燥を行うものである。
【００２３】
ここで上記チャンバー２２内の工業用水洗滌ゾーン１３にガラス板１を投入するに先だって、ガラス板１に界面活性剤を塗布し汚れを遊離させるようにした後、洗滌乾燥装置１２内にガラス板１を搬入させる。
【００２４】
まず、工業用水洗滌ゾーン１３で立掛け状態で搬送中のガラス板１の上部から水温幅１０〜２５℃程度の工業用水または井戸水をスプレー散水し、ガラス板１に付着した埃やホコリ等を含む汚れの大半を洗い落とし、 続く温水洗滌ゾーン１４で、洗滌処理タクトにもよるが約４０℃以上の温水によるシャワー洗滌を行い、工業用水による洗滌では洗滌除去できなかったガラス板１の表面に残存付着の汚れや界面活性剤を完全に洗い落とし、さらに続く純水洗滌ゾーン１５で、ガラス板１の表面が乾燥した後に水滴跡が残らないように、水温が１５〜２５℃で電気伝導度１μＳ／ｃｍ以下の品質の純水によるリンス洗滌により、ガラス板１に付着の不純物を含む工業用水や温水を洗い流し、ガラス板１を純水で覆うようにした。
【００２５】
洗滌中は散水部の霧滴が乾燥ゾーン１６に流入しないように洗滌ゾーンの上部に軸流ファン２４を設けて排気をかけるようにした。 続いて乾燥ゾーン１６に搬入されたガラス板１に対し、上部に設けた加熱ヒーター１７による熱を循環式ファン１８による雰囲気温度が約４０℃の温風にしてガラス板１に噴出し、ガラス板１に残存付着の水滴を蒸発乾燥させた。
【００２６】
次の冷却ゾーン１９に搬送されたガラス板１は、前工程の乾燥ゾーン１６で熱を吸収して熱くなっているので冷却ファン２０で常温程度まで冷却させた後、トンネル状のチャンバー２２を出て次工程に引き継がれる。
【００２７】
冷却ファン２０は外気を取り入れ、高性能フィルター２３で濾過清浄化したものを使用するので外気中の塵埃が再びガラス板１に付着することがないようにした。また、冷却ファン２０で取り込まれ濾過清浄化された空気は乾燥ゾーン１６にも送り込まれ使用され、洗滌ゾーン上に設けた軸流ファン２４にて排出するので塵埃を含んだ外気が装置内に浸入することはない。
【００２８】
本発明の洗滌乾燥装置１２により洗滌及び乾燥したガラス板１は出口側２１を通過後、クリーンな室内でペグ式搬送装置２による立掛け状態から水平状態に姿勢を変更し、次工程であるクリーンルーム内に搬送され合わせガラス処理工程や、プリント工程等のクリーンなガラス面を必要とする工程に搬送移動する。
【００２９】
このように前記ガラス板１をペグ３に立掛け状にして搬送するので、フラット板、湾曲板、寸法形状が異なるガラス板１等をランダムに搬送でき、また前記の洗滌乾燥方法および装置で洗滌、乾燥させたため通常行われている生産品種の変更時等の段取り替えも不要となり、生産性の向上を図ることができるようになった。
【００３０】
以上好適な例について述べたが、本発明はこれに限定されるものではなく、種々の応用が考えられる。 前記界面活性剤の塗布工程は前記チャンバー２２の外で図１のように上部から散布していたが、これをチャンバー２２内に含め、図３のようにチャンバー２２に設け、界面活性剤塗布ゾーン１１としても良く、または、ペグ式搬送装置にガラス板を載置する前に界面活性剤を含浸したスポンジや刷毛等で塗布後、ペグ式搬送装置に移載する。
【００３１】
さらに、ペグ３は水に晒されるため錆びないステンレスが望ましいが、ＳＳ材等に防錆のメッキ処理を施したものでも良い。
【００３２】
【発明の効果】
本発明は、フラットなガラス板、湾曲ガラス板、寸法形状が異なるガラス板等の多品種で形状の異なった湾曲ガラス板を生産品種の変更時に行われる段取り替え時の処理条件を変更せずにランダムに混載状態で連続して洗滌、乾燥できるので、生産性の向上、作業の簡略化、効率化を図ることができる。

[0010]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, a group of glass plates of various sizes and shapes are mixedly loaded, respectively, leaned on rods called pegs, and continuously passed through a washing process and a draining and drying process provided in a tunnel-shaped chamber. The glass plate surface is washed and drained.
[0011]
Prior to putting the glass plate into the washing step, a surfactant is applied to the surface of the glass plate to release dirt, and then the glass plate is conveyed to the washing step. First, spray industrial water from the top of the glass plate that is being transported while standing in the industrial water washing zone, and wash off most of the dirt, dust, etc. released on the glass plate surface. The glass plate surface that was not washed and removed by washing with industrial water was thoroughly washed off any remaining dirt and surfactant on the glass plate surface, and water marks remained after the glass plate surface was dried in the pure water washing zone. In order to avoid this, industrial water or hot water containing impurities adhering to the glass plate surface was washed away by rinsing with pure water.
[0012]
During washing, an axial fan was installed at the upper part of the washing zone so that the mist in the watering part would not flow into the drying zone. Subsequently, the glass plate conveyed to the drying zone was sprayed with heat from a heater provided in the upper part to the glass plate with warm air from a circulation fan, and the water droplets remaining on the glass plate surface were evaporated and dried.
[0013]
Since the glass plate conveyed to the next cooling zone is heated by absorbing heat in the drying zone of the previous process, it is cooled to room temperature with a cooling fan, exits the tunnel-shaped chamber, and is taken over to the next process.
[0014]
The peg is covered with a metal rod such as SUS with a polytetrafluoroethylene tube all around, or the polytetrafluoroethylene plate is fixed to the surface contacting the glass plate, and the glass plate is not scratched. It can be placed in a standing state.
[0015]
As described above, the glass plate is conveyed while standing on a peg, so that a flat plate, a curved plate, a glass plate having a different dimensional shape, etc. can be conveyed at random, and washed and dried by the washing and drying method and apparatus described above. This eliminates the need for changeover when changing production varieties, which is usually done, and improves productivity.
[0016]
【Example】
Embodiments of a glass plate cleaning and drying method and apparatus according to the present invention will be described in detail below with reference to the drawings.
[0017]
FIG. 1 shows a schematic side view of a glass plate washing and drying method and apparatus for explaining an embodiment of the present invention, and FIG. 2 is a perspective view in which a part of a peg type conveying apparatus for explaining an embodiment of the present invention is cut out and omitted. FIG. 3 shows a schematic side view of a glass plate cleaning and drying method and apparatus for explaining another embodiment of the present invention.
[0018]
First, there is a peg type conveying device 2 as shown in FIG. The peg-type transfer device 2 is a device in which a pair of pegs 3 are erected at equal intervals over the entire circumference of the conveyor in the vicinity of both ends in the width direction of the conveyor.
[0019]
The peg 3 has a metal rod 4 made of SUS or the like covered with a tube 5 made of polytetrafluoroethylene on the entire circumference, or a polytetrafluoroethylene tube 5 on the entire circumference or a surface contacting the glass plate 1. A plate made of fluoroethylene is fixed to protect the glass plate 1 placed on the peg 3 so as not to be scratched, but hot air is sprayed in the drying zone 16. Therefore, polytetrafluoroethylene , which is a heat resistant resin, was used.
[0020]
Further, since the peg 3 is exposed to water in the washing machine, it is made of a metal that does not rust, such as stainless steel, so that the surface of the glass plate 1 due to rust is prevented from occurring. Although the glass plate 1 is transported while standing between the pegs 3, even various types of glass plates 1 having different dimensions can be transported in a mixed state.
[0021]
Next, the peg-type transfer device 2 is provided through the entrance side 10 to the exit side 21 in the tunnel-shaped chamber 22 as shown in FIG. 1, and the glass plate 1 is introduced at the entrance side 10 of the chamber 22. It is transferred and taken out at the outlet side 21 and transported to the next process.
[0022]
The chamber 22 includes an industrial water washing zone 13, a hot water washing zone 14, a pure water washing zone 15, a drying zone 16, and a cooling zone 19 from the inlet side 10 side. The process is continuously transported and the glass plate 1 is washed and drained.
[0023]
Here, prior to putting the glass plate 1 into the industrial water washing zone 13 in the chamber 22, a surfactant is applied to the glass plate 1 so as to release dirt, and then the glass plate 1 is placed in the washing / drying device 12. To carry in.
[0024]
First, industrial water or well water having a water temperature range of about 10 to 25 ° C. is sprayed from the upper part of the glass plate 1 being conveyed while standing in the industrial water washing zone 13, and includes dust, dust, etc. adhering to the glass plate 1. Most of the dirt is washed off, and in the subsequent hot water washing zone 14, depending on the washing treatment tact, shower washing with warm water of about 40 ° C. or more is carried out, and remains on the surface of the glass plate 1 that could not be removed by washing with industrial water. In the pure water washing zone 15, the water temperature is 15 to 25 ° C. and the electric conductivity is 1 μS / cm so that no trace of water droplets remains after the surface of the glass plate 1 is dried. Industrial water and hot water containing impurities adhering to the glass plate 1 were washed away by rinsing with pure water of the following quality so that the glass plate 1 was covered with pure water.
[0025]
During washing, an axial fan 24 is provided at the upper part of the washing zone so that the mist droplets in the sprinkling part do not flow into the drying zone 16 to exhaust air. Subsequently, with respect to the glass plate 1 carried into the drying zone 16, the heat from the heater 17 provided in the upper part is blown to the glass plate 1 with the atmospheric temperature of the circulating fan 18 being about 40 ° C. The remaining water droplets on 1 were evaporated to dryness.
[0026]
Since the glass plate 1 transported to the next cooling zone 19 is heated by absorbing heat in the drying zone 16 of the previous process, the glass plate 1 is cooled to about room temperature by the cooling fan 20 and then exited from the tunnel-shaped chamber 22. To the next process.
[0027]
Since the cooling fan 20 uses outside air and is filtered and cleaned by the high-performance filter 23, dust in the outside air is prevented from adhering to the glass plate 1 again. In addition, air that has been taken in by the cooling fan 20 and filtered and purified is also sent to the drying zone 16 for use and discharged by the axial fan 24 provided on the washing zone, so that outside air containing dust enters the apparatus. Never do.
[0028]
After the glass plate 1 washed and dried by the washing and drying device 12 of the present invention passes through the outlet side 21, the posture is changed from a standing state by the peg type conveying device 2 to a horizontal state in a clean room, and a clean room which is the next process It is transported and transported to a process that requires a clean glass surface such as a laminated glass processing process and a printing process.
[0029]
Thus, since the glass plate 1 is conveyed while standing on the peg 3, the flat plate, the curved plate, the glass plate 1 having a different dimensional shape and the like can be randomly conveyed, and the washing and drying method and apparatus can be used for washing. As a result of drying, it is no longer necessary to change setups when changing the production varieties that are normally performed, and productivity can be improved.
[0030]
A preferred example has been described above, but the present invention is not limited to this, and various applications are possible. The surfactant coating step was sprayed from the top as shown in FIG. 1 outside the chamber 22, but this was included in the chamber 22 and provided in the chamber 22 as shown in FIG. 11 or may be applied with a sponge or brush impregnated with a surfactant before placing the glass plate on the peg type transfer device, and then transferred to the peg type transfer device.
[0031]
Further, since the peg 3 is exposed to water, stainless steel that does not rust is desirable. However, the SS material or the like may be subjected to rust-proof plating.
[0032]
【The invention's effect】
The present invention is a flat glass plate, a curved glass plate, and a variety of curved glass plates having different shapes, such as glass plates with different dimensions, without changing the processing conditions at the time of changeover performed when changing the production type. Since it can be washed and dried continuously in a random mixed state, productivity can be improved, work can be simplified, and efficiency can be improved.
