Description
【０００１】[0001]
本考案は、自動原稿送り機能付き複写機の天板として用いられる平板ガラス研 磨装置に関し、特に、導電膜被覆ガラスのような比較的柔らかい板状硬質脆性部 材に対して適度な研磨を行うことができる平板ガラス研磨装置に関する。 The present invention relates to a flat glass polishing device used as a top plate of a copying machine with an automatic document feeding function, and in particular, moderately polishes relatively soft plate-like hard brittle parts such as conductive film coated glass. The present invention relates to a flat glass polishing apparatus capable of performing the same.
【０００２】[0002]
従来、板ガラス等の板状硬質脆性部材の表面を平坦化するための研磨装置とし ては、オスカー型バッチ式研磨機あるいは連続式自動研磨機等が使用されていた 。そしてこれらの研磨機には研磨剤として酸化セリウム等の砥粒が使用されてい た。 Conventionally, an Oscar-type batch-type polishing machine or a continuous automatic polishing machine has been used as a polishing apparatus for flattening the surface of a plate-like hard brittle member such as plate glass. Abrasive grains such as cerium oxide were used as polishing agents in these polishing machines.
【０００３】 図３に、従来の連続式自動研磨機の一例を示す。この連続式自動研磨機１００ は、回転軸１０１、この回転軸１０１から放射状に３方に延長されたアーム１０ ２、このアーム１０２先端に取付けられたパッド１０３からなる研磨手段、及び 平板ガラス１０４の搬送手段（図示せず）とからなる。FIG. 3 shows an example of a conventional continuous automatic polishing machine. This continuous automatic polishing machine 100 includes a rotating shaft 101, an arm 102 radially extending from the rotating shaft 101 in three directions, a polishing means including a pad 103 attached to the end of the arm 102, and a flat glass 104. And a transporting means (not shown).
【０００４】 上記連続式自動研磨機１００による研磨は次のようにして行う。すなわち、前 記搬送手段によって平板ガラス１０４を一定方向に一定速度で搬送しながら、回 転軸１０１を左回りに回転させ、かつ研磨剤スラリを含むパッド１０３を左回り に回転させる。すると、平板ガラス１０４の表面は弧をえがくように磨かれるた め方向性を持たない理想的な平滑面となる。Polishing by the continuous automatic polishing machine 100 is performed as follows. That is, while the flat glass 104 is being conveyed in a constant direction at a constant speed by the above-mentioned conveying means, the rotating shaft 101 is rotated counterclockwise and the pad 103 containing the abrasive slurry is rotated counterclockwise. Then, the surface of the flat glass 104 becomes an ideal smooth surface having no directionality because it is polished so as to obscure an arc.
【０００５】[0005]
しかし、前記板状硬質脆性部材の中には硬質ではあっても比較的柔らかいもの がある。例えば、自動原稿送り機能付き複写機の天板用ガラスの場合は、錫をド ープしたインジウム膜（ＩＴＯ膜）、酸化錫膜等で表面を被覆して導電性を持た せ帯電を防止している。これらＩＴＯ膜等で被覆したガラス板は、複写機に取付 ける前に膜表面の微細な凹凸を研磨して摩擦係数を低減する必要があるが、ＩＴ Ｏ膜は比較的柔らかいため例えばスラリ状の研磨剤を含ませた布で擦る程度でも かなりの低摩擦面を得ることができる。 However, some of the plate-like hard and brittle members are hard but relatively soft. For example, in the case of glass for the top plate of a copying machine with an automatic document feeding function, the surface is covered with an indium film (ITO film) doped with tin, a tin oxide film, etc. to make it conductive and prevent electrification. ing. A glass plate coated with these ITO film or the like needs to be polished for fine irregularities on the film surface before being mounted on a copying machine to reduce the coefficient of friction, but since the ITO film is relatively soft, it has a slurry-like shape. It is possible to obtain a considerably low friction surface even by rubbing with a cloth containing an abrasive.
【０００６】 上述の比較的柔らかい面を有する平板ガラスの場合は、前記のバッチ式あるい は連続式研磨機を使って研磨すると被膜が削られ過ぎて品質低下をもたらしたり 、そこまで行かない場合であっても過剰に研磨されるという難点があった。また 、前記バッチ式研磨機の場合はこの研磨機への平板ガラスの脱着の手間がかかる こと、前記図３に示した連続式研磨機の場合は複雑な機構であるためメンテナン スに手間がかかること等の問題もあった。このため、より簡便でしかも過不足の ない研磨の行える自動研磨装置が求められていた。In the case of the above-mentioned flat glass having a relatively soft surface, when the above-mentioned batch type or continuous type polishing machine is used for polishing, the coating film is excessively scraped, resulting in deterioration of quality, or when it does not reach there. However, there was a problem that it was excessively polished. Further, in the case of the batch type polishing machine, it takes a lot of time to attach and detach the flat glass to the polishing machine, and in the case of the continuous type polishing machine shown in FIG. 3, since it has a complicated mechanism, the maintenance is troublesome. There were also some problems. For this reason, there has been a demand for an automatic polishing apparatus that is simpler and can perform polishing without excess or deficiency.
【０００７】 本考案は、従来の技術が有するこのような問題点を解決するためになされたも のであり、その目的とするところは、構造が簡素で取扱いが容易であり、しかも 比較的柔らかい板状硬質脆性部材に対して適度な研磨を行うことのできる平板ガ ラス研磨装置を提供しようとするものである。The present invention has been made in order to solve the above-mentioned problems of the prior art. The purpose of the present invention is that the structure is simple, the handling is easy, and the plate is relatively soft. An object of the present invention is to provide a flat plate glass polishing apparatus capable of performing appropriate polishing on a hard and brittle member.

A roll-shaped polishing means including an elastic core material portion and an abrasive skin portion is included.

以下に本考案の実施例を図に基づいて説明する。 図１は、本考案に基づく平板ガラス研磨装置の一例を示す斜視図である。同図 に示すように、この平板ガラス研磨装置１は平板ガラス２の搬送手段である複数 のピニオン３およびこれらピニオン３と噛み合って平板ガラス２を一定速度で搬 送するカセット４、及び研磨手段であるローラ５を主要部としている。前記平板 ガラス２の例としては、０．７〜２ｍｍ厚のガラス基材上に３０〜３００ｎｍ厚 のＩＴＯ膜あるいは酸化錫膜を形成したものを挙げることができる。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a flat glass polishing apparatus according to the present invention. As shown in the figure, the flat glass polishing apparatus 1 comprises a plurality of pinions 3 which are means for transporting the flat glass 2, a cassette 4 which meshes with the pinions 3 to transport the flat glass 2 at a constant speed, and a polishing means. A certain roller 5 is the main part. Examples of the flat glass 2 include a glass substrate having a thickness of 0.7 to 2 mm and an ITO film or a tin oxide film having a thickness of 30 to 300 nm formed thereon.
【００１１】 前記複数のピニオン３の各スプロケット６はチェーン７によって連結されてお り、端部に配置されスプロケット６ａはベルト８によって駆動用モータ９に連絡 されている。また、前記ローラ５は例えばスポンジ状のゴムからなる芯材部５ａ と例えばＡl2Ｏ3等の砥粒を接着剤で布、紙等に貼り付けてなる表皮部５ｂとか ら構成されている。そして、このローラ５は、支持枠１０に上下動自在に取付け られた軸受１１、この軸受１１に支持されるローラ５の回転軸１２、及び図示し ない駆動用モータによって、平板ガラス２の表面に適正な圧力をかけながら研磨 することができる。The sprockets 6 of the plurality of pinions 3 are connected by a chain 7, and the sprockets 6 a arranged at the ends are connected to a drive motor 9 by a belt 8. The roller 5 is composed of a core portion 5a made of, for example, sponge-like rubber, and a skin portion 5b made by attaching abrasive grains such as Al 2 O 3 to cloth or paper with an adhesive. The roller 5 is attached to the surface of the flat glass 2 by a bearing 11 mounted on a support frame 10 so as to be vertically movable, a rotary shaft 12 of the roller 5 supported by the bearing 11, and a drive motor (not shown). It is possible to polish while applying proper pressure.
【００１２】 次に本考案に基づく平板ガラス研磨装置１の使用方法を説明する。 図２は、平板ガラス研磨装置１の作用を示す側面方向からの概略図である。同 図において、平板ガラス２はカセット４内にセットされ、右回転する複数のピニ オン３によって右方向に搬送される。一方、ローラ５も右回転させるためこのロ ーラ５の表皮部５ｂと平板ガラス２との接点においては、ローラ５は平板ガラス ２と相対する方向に回転することとなりその結果平板ガラス２の表面が研磨され る。Next, a method of using the flat glass polishing apparatus 1 according to the present invention will be described. FIG. 2 is a schematic side view showing the operation of the flat glass polishing apparatus 1. In the figure, the flat glass 2 is set in a cassette 4 and is conveyed rightward by a plurality of pinions 3 that rotate clockwise. On the other hand, since the roller 5 also rotates to the right, at the contact point between the skin 5b of the roller 5 and the flat glass 2, the roller 5 rotates in the direction opposite to the flat glass 2, and as a result, the surface of the flat glass 2 is rotated. Are polished.
【００１３】 前記搬送手段としては上記ピニオン３によるほか、例えばピニオン３に代えて 上挟みロール及び搬送用ロールを使用して平板ガラス２の上下を挟みながら搬送 することもできる。また、カセット４は必ずしも使う必要はない。Besides the pinion 3 as the conveying means, it is possible to convey the flat glass 2 while sandwiching the upper and lower sides of the flat glass 2 using, for example, an upper sandwiching roll and a transport roll instead of the pinion 3. Further, the cassette 4 does not necessarily have to be used.
【００１４】 さらに、研磨手段として上記の芯材部５ａ及び表皮部５ｂからなるローラ５を 用いる場合、平板ガラス２の硬度の程度によって例えば粗い布、ポリエステル布 等を表皮部５ｂとして使用することもできる。Further, when the roller 5 composed of the core 5a and the skin 5b is used as the polishing means, a rough cloth, polyester cloth or the like may be used as the skin 5b depending on the hardness of the flat glass 2. it can.
【００１５】 本考案に基づく上記各装置によって形成した導電膜付きの平板ガラス２を自動 原稿送り機能付き複写機の天板として用いれば、原稿との摩擦が小さくまた帯電 することがないため、原稿詰り等のトラブルを防止することができる。If the flat glass 2 with a conductive film formed by each of the above devices according to the present invention is used as a top plate of a copying machine with an automatic document feeding function, the friction with the document is small and the document is not charged. Problems such as clogging can be prevented.
【００１６】 本考案に基づく実施例をさらに詳細に説明する。実施例１ 図１の平板ガラス研磨装置１を用いて、化学的気相成長法（ＣＶＤ法）により 酸化錫膜を形成したフロートガラス２の表面を研磨した。ローラ５は、スポンジ 製の芯材部５ａの周囲に＃２０００のエメリーペーパ（Ａl2Ｏ3砥粒を貼着した ペーパ。＃１２００以上を使用する。）を巻き付けて表皮部５ｂとした半径３０ ｍｍのものを使用した。また、このローラ５の回転数は２回転／秒とし、平板ガ ラス２の搬送スピードは３０ｍｍ／秒とした。The embodiment according to the present invention will be described in more detail. Example 1 Using the flat glass polishing apparatus 1 shown in FIG. 1, the surface of the float glass 2 having a tin oxide film formed thereon was polished by a chemical vapor deposition method (CVD method). The roller 5 has a radius of 30 which is formed by winding # 2000 emery paper (paper having Al 2 O 3 abrasive grains adhered thereon; use # 1200 or more) around the sponge core 5a to form the skin 5b. The thing of mm was used. The rotation speed of the roller 5 was 2 rotations / second, and the transport speed of the flat glass 2 was 30 mm / second.
【００１７】 研磨前後の平板ガラス２の摩擦係数測定結果を表１に示す。表中の平行方向と はローラ５の回転方向と平行に摩擦係数を測定した値であり、垂直方向とはロー ラ５の回転方向と９０°異なる方向の摩擦係数を測定した値である。なお、摩擦 係数の測定には新東科学製の「ＨＥＩＤＯＮ−１４」表面測定機を使用した。Table 1 shows the measurement results of the coefficient of friction of the flat glass 2 before and after polishing. In the table, the parallel direction is a value obtained by measuring the friction coefficient parallel to the rotation direction of the roller 5, and the vertical direction is a value obtained by measuring the friction coefficient in a direction different from the rotation direction of the roller 5 by 90 °. A "HEIDON-14" surface measuring machine manufactured by Shinto Kagaku Co., Ltd. was used to measure the friction coefficient.
【００１８】[0018]
【表１】 [Table 1]
【００１９】 上記表１から明らかなように良好な摩擦低減効果を得ることができた。摩擦係 数は平行方向ばかりでなく垂直方向についても十分に低下していた。なお、本実 施例は研磨剤スラリ等を使用しない乾式研磨であるため、研磨後の平板ガラス２ 表面の清掃が容易であり、水等による洗浄工程を省略することができた。As is clear from Table 1 above, a good friction reducing effect could be obtained. The friction coefficient decreased sufficiently not only in the parallel direction but also in the vertical direction. Since the present example is a dry polishing that does not use an abrasive slurry or the like, the surface of the flat glass 2 after polishing can be easily cleaned, and the cleaning step with water or the like can be omitted.
