ここで、前記作業台１０、検査部１１及び移送機３０は、公知の技術をそのまま適用することができるためこれらの詳細な説明は省いて、以下、本願発明の要旨である移送部２０に関して詳しく説明する。   Here, since the work table 10, the inspection unit 11 and the transfer machine 30 can apply known techniques as they are, detailed descriptions thereof will be omitted, and the transfer unit 20 which is the gist of the present invention will be described in detail below. explain.

前記移送部２０は、図３、図４に示すように、吐出ファン２１ａが備えられたファンハウジング２１と、該ファンハウジング２１の上面に載置されるエアチャンバ２２と、該エアチャンバ２２の上部に覆い被せるベース板２３と、このベース板２３の各通孔２３ａに覆い被せるフィルタ２４（図５）と、該フィルタ２４の上面に覆い被せると共にベース板２３上面の該当の部分にそれぞれ結合される複数個の片板２５とを含む構成になっている。   As shown in FIGS. 3 and 4, the transfer unit 20 includes a fan housing 21 provided with a discharge fan 21 a, an air chamber 22 placed on the upper surface of the fan housing 21, and an upper portion of the air chamber 22. A base plate 23 to be covered, a filter 24 (FIG. 5) to be covered to each through hole 23a of the base plate 23, and an upper surface of the filter 24 and a corresponding portion on the upper surface of the base plate 23. The structure includes a plurality of single plates 25.

前記ファンハウジング２１は、開放された上面がクリーンフィルタ２１ｄで覆われ、内部に上方へエア（空気）を吐出させる吐出ファン２１ａを備えた四角の箱状になっている。そして、前記ファンハウジング２１の底面には、開放された上方からクリーンフィルタ２１ｄを通してエアを円滑に排出させるための通孔２１ｂと、吐出ファン２１ａに電源を供給するための電源ケーブル２１ｃ等が通過する通孔２１ｂと、が設けられている。このような通孔２１ｂは、ファンハウジング２１の側面にも設けられてもよい。   The upper surface of the fan housing 21 is covered with a clean filter 21d, and has a rectangular box shape with a discharge fan 21a that discharges air (air) upward. The bottom surface of the fan housing 21 passes through a through hole 21b for smoothly discharging air from above the open through the clean filter 21d, a power cable 21c for supplying power to the discharge fan 21a, and the like. And a hole 21b. Such a through hole 21 b may also be provided on the side surface of the fan housing 21.

そして、前記ファンハウジング２１のクリーンフィルタ２１ｄは、吐出ファン２１ａから吐出されるエアが直接エアチャンバ２２内へ流入されないように、エア中に含まれている微細埃等を取り除く第一次のエア洗浄機能と共に、エアの吐出圧を緩和させるための機能を有する。ここで、前記クリーンフィルタ２１ｄは、ファンハウジング２１上に接着剤等を用いて接着固定することができる。   The clean filter 21d of the fan housing 21 is a primary air cleaning function that removes fine dust and the like contained in the air so that the air discharged from the discharge fan 21a does not flow directly into the air chamber 22. At the same time, it has a function for reducing the discharge pressure of air. Here, the clean filter 21d can be bonded and fixed onto the fan housing 21 using an adhesive or the like.

前記エアチャンバ２２は、吐出ファン２１ａによって吐出されたエアが満たされ、継続的なエア吐出によってエアを上方へ排出する、四角の箱形状を有する。ファンハウジング２１の上面に載置されるエアチャンバ２２は、底面の中央部に、ファンハウジング２１の開放された上部と連通される貫通孔２２ａが設けられ、内部にエアが満たされる空間部２２ｂが設けられている。その上面の全体は、ベース板２３が密着結合されるように開放されている。   The air chamber 22 has a square box shape that is filled with air discharged by the discharge fan 21a and discharges air upward by continuous air discharge. The air chamber 22 placed on the upper surface of the fan housing 21 is provided with a through hole 22a that communicates with the opened upper portion of the fan housing 21 at the center of the bottom surface, and a space portion 22b that is filled with air therein. Is provided. The entire upper surface is opened so that the base plate 23 is tightly coupled.

すなわち、前記エアチャンバ２２では、吐出ファン２１ａによって吐出されたエアがエアチャンバ２２の空間部２２ｂ内に一次的に満たされる。続いて、吐出ファン２１ａによってエアチャンバ２２内へ流入されて該エアチャンバ２２の空間部２２ｂを満たしていたエアは、上方へ押し出されるようになり、ベース板２３の通孔２３ａを通って上方へ排出される（図６）。   That is, in the air chamber 22, the air discharged by the discharge fan 21 a is primarily filled in the space 22 b of the air chamber 22. Subsequently, the air that has flowed into the air chamber 22 by the discharge fan 21a and filled the space 22b of the air chamber 22 is pushed upward, and passes upward through the through hole 23a of the base plate 23. It is discharged (FIG. 6).

前記ベース板２３は、エアチャンバ２２の開放された上部に覆い被せて密着される四角の板材状であり、その表面には、上述したように、上下方向に貫通した複数の通孔２３ａが設けられている。ここで、前記ベース板２３の通孔２３ａは、検査部１１が設けられている作業台１０の中央部に行くほどぎっしりと密に形成されている。   The base plate 23 is in the form of a square plate that covers and closely adheres to the open upper portion of the air chamber 22, and has a plurality of through holes 23a penetrating in the vertical direction on the surface thereof, as described above. It has been. Here, the through holes 23a of the base plate 23 are formed so densely that they go to the center of the work table 10 where the inspection unit 11 is provided.

前記フィルタ２４は、ベース板２３の各通孔２３ａを覆い被せ、エアチャンバ２２内のエアをベース板２３の通孔２３ａへ直ちに排出させずに排出圧がある程度緩和されるようにし、結果的に、エアが該フィルタ２４を通って滲み出る程度のエア圧で排出されるようにするためのものである。フィルタ２４として、主に焼結フィルタを用いる。   The filter 24 covers each through hole 23a of the base plate 23 so that the air in the air chamber 22 is not immediately discharged to the through hole 23a of the base plate 23, so that the discharge pressure is relieved to some extent. The air is discharged at an air pressure that oozes through the filter 24. A sintered filter is mainly used as the filter 24.

ここで、前記フィルタ２４の大きさは、ベース板２３の各通孔２３ａのみを個別に覆い被せられる程度の大きさにすることもでき、また、本実施例のようにそれぞれの片板２５に当たる大きさにすることもできる。例えば、片板２５にエア吐出孔２５ａが５つ設けられた場合には、前記フィルタ２４もベース板２３の５つの通孔２３ａを覆い被せて該当片板２５の大きさを超えない大きさで形成することが望ましい。   Here, the size of the filter 24 can be set to such a size that only the through holes 23a of the base plate 23 can be individually covered, and each filter 24 corresponds to each piece plate 25 as in this embodiment. It can also be sized. For example, when five air discharge holes 25a are provided in the single plate 25, the filter 24 also covers the five through holes 23a of the base plate 23 so as not to exceed the size of the corresponding single plate 25. It is desirable to form.

前記片板２５は、フィルタ２４の上面を覆い被せつつベース板２３の上面の該当部分にそれぞれ結合され、それぞれの表面にはベース板２３の通孔２３ａに対応して上下に貫通する複数のエア吐出孔２５ａが設けられている。片板２５は、長方形の板材状になっている。さらに、これらが縦横に配置された状態で片板２５間の離隔隙間が縦方向（前後方向）及び横方向に沿って空気層緩和溝部２５ｂ（図３、図６）を形成する。   The piece plate 25 is coupled to a corresponding portion of the upper surface of the base plate 23 while covering the upper surface of the filter 24, and each surface has a plurality of air penetrating vertically corresponding to the through holes 23 a of the base plate 23. A discharge hole 25a is provided. The single plate 25 has a rectangular plate shape. Further, in the state where these are arranged vertically and horizontally, the separation gap between the strips 25 forms the air layer relaxation groove portion 25b (FIGS. 3 and 6) along the longitudinal direction (front-rear direction) and the lateral direction.

前記ベース板２３上に結合される複数の片板２５に関してより詳しく説明する。片板２５は、図４に示すように、検査部１１に隣接するベース板２３の上面に配設されて横方向に長く延長された第１の片板２５１と、該第１の片板２５１の縦方向の隣接後方に所定距離で離隔配設された、狭幅長方形の板材状を有し、横方向に沿ってそれぞれ所定間隔ずつ離隔配設される複数の第２の片板２５２と、該第２の片板２５２の縦方向の隣接後方に所定距離で離隔配設された、広幅長方形の板材状を有し、横方向に沿ってそれぞれ所定間隔ずつ離隔配設される複数の第３の片板２５３と、を備えて構成されている。   The plurality of single plates 25 coupled on the base plate 23 will be described in more detail. As shown in FIG. 4, the single plate 25 includes a first single plate 251 that is disposed on the upper surface of the base plate 23 adjacent to the inspection unit 11 and extends long in the lateral direction, and the first single plate 251. A plurality of second strips 252 each having a narrow rectangular plate shape spaced apart at a predetermined distance in the rearward direction in the vertical direction and spaced apart by a predetermined distance along the horizontal direction; A plurality of third plates having a wide rectangular plate shape spaced apart by a predetermined distance behind the second piece 252 in the vertical direction and spaced apart by a predetermined distance along the horizontal direction. And a single plate 253.

そして、前記第１の片板２５１の表面全体には、長さ方向（前後方向）に沿って凹状の空気層緩和溝部２５１ａが横方向に所定間隔ずつ離隔されて複数形成されている。すなわち、前記第１の片板２５１には、第１、第２、及び第３の各片板２５１，２５２，２５３の間に形成されている空気層緩和溝部２５ｂのような機能を行わせる、空気層緩和溝部２５１ａが表面上に直接切削等によって凹状に形成されている。   A plurality of concave air layer relaxation groove portions 251a are formed on the entire surface of the first piece plate 251 along the length direction (front-rear direction) with a predetermined interval in the lateral direction. That is, the first piece plate 251 performs a function such as an air layer relaxation groove portion 25b formed between the first, second, and third piece plates 251, 252, 253. The air layer relaxation groove 251a is formed in a concave shape on the surface by direct cutting or the like.

そして、前記第１の片板２５１には、空気層緩和溝部２５１ａを除いた残り表面の全体に、それぞれ長さ方向に沿って並ぶ一対のエア吐出孔２５１ｂが、横方向に沿って繰り返して連続配設形成されている。ここで、前記第１の片板２５１のエア吐出孔２５１ｂに対応してベース板２３上にも同一大きさ及び同一配設構造で通孔２３ａが設けられている。   The first piece plate 251 has a pair of air discharge holes 251b continuously arranged along the length direction on the entire remaining surface excluding the air layer relaxation groove 251a. An arrangement is formed. Here, corresponding to the air discharge holes 251b of the first piece plate 251, the base plate 23 is also provided with through holes 23a having the same size and the same arrangement structure.

第２の片板２５２と第３の片板２５３とは、第２の片板２５２が、第３の片板２５３より幅がやや狭く長さがやや短いこと以外は、略同形状である。その違いは、より具体的には、第２の片板２５２上には４つのエア吐出孔２５２ａが形成されていて、第３の片板２５３上には５つのエア吐出孔２５３ａが設けられている点である。そして、第２の片板２５２は、長さ方向に１列に配設されており、第３の片板２５３は、長さ方向に２列に配設されている。   The second piece plate 252 and the third piece plate 253 have substantially the same shape, except that the second piece plate 252 is slightly narrower and slightly shorter in length than the third piece plate 253. More specifically, the difference is that four air discharge holes 252a are formed on the second piece plate 252 and five air discharge holes 253a are provided on the third piece plate 253. It is a point. The second piece plates 252 are arranged in one row in the length direction, and the third piece plates 253 are arranged in two rows in the length direction.

このような構成による本発明の板ガラス移送装置では、図６に示すように、エアが、吐出ファン２１ａの回転によって上方へ吐出され、一次的にエアチャンバ２２の空間部２２ｂ内に満たされると共に、継続的な吐出ファン２１ａのエア吐出によってエアチャンバ２２の空間部２２ｂから上方へ押し出されつつエアチャンバ２２の上面に結合されているベース板２３の通孔２３ａを通って上方へ排出される。このとき、前記ベース板２３の通孔２３ａを通って上方へ排出されるエアは、フィルタ２４によって排出速度が緩和されつつ、フィルタ２４を通って滲み出るように片板２５のエア吐出孔２５ａへ排出され、最終的に片板２５上において一種の空気層を形成する。   In the plate glass transfer device of the present invention having such a configuration, as shown in FIG. 6, air is discharged upward by the rotation of the discharge fan 21a, and is temporarily filled in the space 22b of the air chamber 22, The air is continuously discharged from the space 22b of the air chamber 22 and is discharged upward through the through hole 23a of the base plate 23 coupled to the upper surface of the air chamber 22 by the air discharge of the discharge fan 21a. At this time, the air discharged upward through the through hole 23 a of the base plate 23 is evacuated by the filter 24, and oozes out through the filter 24 to the air discharge hole 25 a of the single plate 25. It is discharged and finally forms a kind of air layer on the piece plate 25.

すなわち、板ガラス４０と片板２５間に形成された空気層に、継続的なエアの補充（流れ）が行われ、持続的に空気層が維持できる。これは換言すれば、前記片板２５上に形成された空気層が片板２５上に載置される板ガラス４０を支えると共に、空気層を形成したエアが片板２５の上部に形成された空気層緩和溝部２５１ａ、及び片板２５間に形成された空気層緩和溝部２５ｂを通って移送部２０の四方外側へ排出され、空気層は、これらの過程を繰り返しつつ、結果的に板ガラス４０を片板２５上から所定の高さ離隔させた状態に浮上させる。   That is, the air layer formed between the plate glass 40 and the single plate 25 is continuously replenished (flowed) with air, and the air layer can be maintained continuously. In other words, the air layer formed on the piece plate 25 supports the plate glass 40 placed on the piece plate 25, and the air forming the air layer is formed on the upper side of the piece plate 25. The layer relaxation groove 251a and the air layer relaxation groove 25b formed between the single plates 25 are discharged to the outside of the transfer unit 20 in the four directions. The air layer repeats these processes, and as a result, the plate glass 40 is broken into pieces. It floats in a state separated from the plate 25 by a predetermined height.

そして、前記空気層緩和溝部２５ｂ、及び空気層緩和溝部２５１ａは、片板２５上の全体空気層のボリュームを緩和させる役割を果たし、その結果、板ガラス４０の中央部が膨れ上がる、いわゆる張出（バルジング）現象を防止する。例えば、従来のように、空気層緩和溝部２５ｂのない扁平な平板において空気層を形成させる場合、平板中央部の空気より枠側の空気が比較的に外部へ迅速に抜けて行くので、全体として平板の枠側より中央部の空気層が厚く形成され、その結果、板ガラス４０の中央部が上方に膨れ上がる張出現象が発生するが、本発明のように、空気層緩和溝部２５ｂを形成させて空気層のエアがこれら空気層緩和溝部２５ｂへ排出されるようにすることにより、空気層のボリュームを一部緩和できるようになり、板ガラス４０の張出現象を防止できる。   The air layer relaxation groove portion 25b and the air layer relaxation groove portion 251a play a role of relaxing the volume of the entire air layer on the piece plate 25. As a result, the central portion of the plate glass 40 swells, so-called overhang ( Prevent bulging phenomenon. For example, when the air layer is formed on a flat flat plate without the air layer relaxation groove 25b as in the conventional case, the air on the frame side relatively quickly escapes from the air at the center of the flat plate to the outside. The air layer at the center part is formed thicker than the flat frame side, and as a result, a protruding phenomenon occurs in which the center part of the plate glass 40 swells upward. However, as in the present invention, the air layer relaxation groove part 25b is formed. By discharging the air in the air layer to these air layer relaxation grooves 25b, the volume of the air layer can be partially relaxed, and the overhang phenomenon of the plate glass 40 can be prevented.

次に、図７を参照して、本発明の第２の実施例を説明する。第２の実施例は、第１の実施例における移送部２０に変えて、図７に示す移送部２０を用いるものである。この移送部２０の第１の片板２５１’は、第１の実施例における第１の片板２５１の吐出孔２５１ｂ（従って通孔２３ａ）の個数と配置を変えたものであり、第２の実施例の他の構成は第１の実施例と同様である。第１の片板２５１’は、空気層緩和溝部２５１ａ’を除いた残り表面のうち、前後方向に沿って一対のエア吐出孔２５１ｂ’が設けられている表面と単一吐出孔２５１ｃ’が設けられている表面とが横方向に沿って繰り返して連続配設されたものである。この実施例は、第１の実施例における吐出孔２５１ｂの個数と配置を変えて、空気層の厚みの均一性を確保するものである。   Next, a second embodiment of the present invention will be described with reference to FIG. The second embodiment uses a transfer section 20 shown in FIG. 7 in place of the transfer section 20 in the first embodiment. The first piece plate 251 ′ of the transfer unit 20 is obtained by changing the number and arrangement of the discharge holes 251b (and hence the through holes 23a) of the first piece plate 251 in the first embodiment. Other configurations of the embodiment are the same as those of the first embodiment. Of the remaining surface excluding the air layer relaxation groove 251a ′, the first piece plate 251 ′ has a surface in which a pair of air discharge holes 251b ′ are provided along the front-rear direction and a single discharge hole 251c ′. The surface is repeatedly arranged along the horizontal direction. In this embodiment, the number and arrangement of the discharge holes 251b in the first embodiment are changed to ensure the uniformity of the thickness of the air layer.

次に、図８、図９を参照して、本発明の第３の実施例を説明する。前記板ガラス４０の張出現象を防止する方法として、前記第１の実施例における空気層緩和溝部２５ｂの空間を拡張させてエア排出量を増加させる方法を用いることもできる。これを実現する移送部２０を用いる例が実施例３である。この実施例における第２の片板２５２’及び第３の片板２５３’の枠面の下端部には、それぞれ内側への凹状を有する凹溝部２５２ａ’，２５３ａ’が形成されている。   Next, a third embodiment of the present invention will be described with reference to FIGS. As a method of preventing the overhang phenomenon of the plate glass 40, a method of increasing the air discharge amount by expanding the space of the air layer relaxation groove portion 25b in the first embodiment can be used. An example using the transfer unit 20 for realizing this is the third embodiment. In this embodiment, recessed portions 252a 'and 253a' having inward concave shapes are formed at the lower end portions of the frame surfaces of the second piece plate 252 'and the third piece plate 253', respectively.

次に、図１０を参照して、本発明の第４の実施例を説明する。前記板ガラス４０の張出現象を防止する方法として、エア吐出孔を通る空気漏出量を調節することもできる。これは、図１０に示す板ガラス移送装置の第４の実施例のように、それぞれ隣接する第３の片板２５３’’同士において、長さ方向及び横方向に沿って４個のエア吐出孔２５３ａ’’が設けられている第３の片板２５３’’と、５個のエア吐出孔２５３ａ’’が設けられている第３の片板２５３’’とを交互に混合配設させることによって実現できる。   Next, a fourth embodiment of the present invention will be described with reference to FIG. As a method for preventing the sheet glass 40 from protruding, the amount of air leakage passing through the air discharge holes can be adjusted. This is because, as in the fourth embodiment of the glass sheet transfer device shown in FIG. 10, the four air discharge holes 253a are arranged along the length direction and the horizontal direction between the adjacent third piece plates 253 ''. This is realized by alternately arranging the third piece plate 253 '' provided with '' and the third piece plate 253 '' provided with five air discharge holes 253a ''. it can.

このように、片板２５上に空気層が形成された状態で検査対象である板ガラス４０が作業台１０上の移送部２０に移されれば、この時から板ガラス４０は空気層によって所定高さ上方に浮上した状態となる。この際、作業台１０の移送機３０が板ガラス４０の一側面を真空吸着して検査部１１の方へ摺動移送させつつ板ガラス４０の不良検査が行われると共に、この検査部１１を通った板ガラス４０は移送され続け、その次の段階へ案内される。このように、板ガラス４０は不良検査を受ける間、移送部２０と接触することなくエア浮上した状態で移送されるので、接触摩擦等いかなる揺れもなく検査が行われる。   In this way, if the plate glass 40 to be inspected is transferred to the transfer unit 20 on the work table 10 with the air layer formed on the single plate 25, the plate glass 40 has a predetermined height by the air layer from this time. It will be in a state of floating upward. At this time, the transfer machine 30 of the work table 10 vacuum-adsorbs one side of the plate glass 40 and slides and transfers the plate glass 40 toward the inspection unit 11, and a defect inspection of the plate glass 40 is performed. 40 continues to be transferred and guided to the next stage. Thus, since the plate glass 40 is transferred in a state of air levitation without being in contact with the transfer unit 20 during the defect inspection, the inspection is performed without any shaking such as contact friction.

次に、図１１を参照して、本発明の第５の実施例を説明する。この板ガラス移送装置の第５の実施例では、前記片板２５の代わりに、フィルタ２４の上面を覆い被せつつベース板２３の上面全体に対応配設され、さらにその表面にベース板２３の通孔２３ａと対応して上下に貫通された複数のエア吐出孔２６ａが形成され、各エア吐出孔２６ａの隣接部には表面全体にかけて縦、横方向に沿って所定深さの凹状の空気層緩和溝部２６ｂが備えられた、上板２６を適用している。   Next, a fifth embodiment of the present invention will be described with reference to FIG. In the fifth embodiment of the glass sheet transfer device, instead of the single plate 25, the filter 24 is covered with the entire upper surface of the base plate 23 while covering the upper surface of the filter 24. A plurality of air discharge holes 26a vertically formed corresponding to 23a are formed, and a concave air layer relaxation groove portion having a predetermined depth along the vertical and horizontal directions over the entire surface is formed adjacent to each air discharge hole 26a. An upper plate 26 provided with 26b is applied.
