The substrate support portions 12 constituting each shelf are formed in a planar plate shape extending horizontally in the direction orthogonal to the substrate transport direction (that is, the substrate width direction). In the embodiment, 5) are arranged at predetermined intervals in the substrate transport direction.
With the above configuration, the substrate cassette 1 can be stored in multiple stages in the vertical direction while holding the glass substrate 4 in the horizontal posture by the substrate support portion 12.

基板支持部12のうち、基板搬送方向中央に位置する基板支持部12aの両端には、カプラ15が接続されている。このカプラ15は、基板支持部12に形成された吹出孔14と、これら吹出孔14に管路を介して圧搾空気を供給する送気ブロワ又はコンプレッサ(送気源)との連通を可能にするものである。
Inside the substrate support portion 12, a blowout hole 14 is formed that opens to an upper surface (substrate support surface) 12 </ b> A thereof. The blow holes 14 are formed at regular intervals over the substantially entire length of the upper surface 12A in the length direction (direction orthogonal to the substrate transport direction), and one row of the blow hole groups along the length direction is the front side in the substrate transport direction. And it is parallel to the rear side.

Is.

すなわち、多数の搬送ローラ24を備えた搬送ローラユニット2には、上記管路の先端に装着されたノズル(図示略)が固定されている。そして、搬送ローラ24を基板カセット1内に差し込むと、その差し込み動作に伴ってノズルがカプラ15の一端側に連結し、送気ブロワから各基板支持部12に圧搾空気が供給可能になる。
また、搬送ローラ24を基板カセット1外に抜き出すと、その抜き出し動作に伴ってノズルがカプラ15から離脱し、送気ブロワから各基板支持部12への送気が遮断される。
That is, a nozzle (not shown) attached to the tip of the pipe is fixed to the transport roller unit 2 including a large number of transport rollers 24. When the transport roller 24 is inserted into the substrate cassette 1, the nozzle is connected to one end of the coupler 15 along with the insertion operation, and compressed air can be supplied from the air supply blower to each substrate support 12.
Further, when the conveying roller 24 is extracted out of the substrate cassette 1, the nozzle is detached from the coupler 15 along with the extracting operation, and the air supply from the air supply blower to each substrate support portion 12 is blocked.

各カプラ15には、基板搬送方向前側及び後側に向かって延びる分配管16が接続されている。この分配管16は、カプラ15が接続された基板支持部12a以外の基板支持部12の端部にそれぞれ連結されていて、これら基板支持部12にも送気ブロワから供給された圧搾空気を分配できるようになっている。
そして、送気ブロワを駆動すると、管路,ノズル,カプラ15,及び分配管16を経て各基板支持部12に供給された圧搾空気が、吹出孔14を通って上方に向かって噴射されるので、基板カセット1内に搬入出されるガラス基板4の下面中央部4cは非接触に支持される。
Each coupler 15 is connected to a distribution pipe 16 extending toward the front side and the rear side in the substrate transport direction. The distribution pipes 16 are respectively connected to the end portions of the substrate support portion 12 other than the substrate support portion 12a to which the coupler 15 is connected, and distribute the compressed air supplied from the air supply blower to these substrate support portions 12 as well. It can be done.
When the air blower is driven, the compressed air supplied to each substrate support 12 through the pipe line, the nozzle, the coupler 15 and the distribution pipe 16 is jetted upward through the blowout holes 14. The lower surface central portion 4c of the glass substrate 4 carried into and out of the substrate cassette 1 is supported in a non-contact manner.

基板カセット1は、ガラス基板4を基板カセット1内の任意の棚段に搬入したり、基板カセット1内の任意の棚段からガラス基板4を搬出できるように、上下方向に定位置に支持された搬送ローラ24に対し、相対的に昇降移動できるようになっている。
そのためのカセット昇降機構3は、基板カセット1の底部11cを支持するブラケット31と、サーボ駆動によりブラケット31を上下動させるボールネジと、ブラケット31の上下動を案内するガイド32と、基板カセット1の上下方向の位置出しに用いられるセンサとを備えて構成されている。
The substrate cassette 1 is supported at a fixed position in the vertical direction so that the glass substrate 4 can be carried into an arbitrary shelf in the substrate cassette 1 and the glass substrate 4 can be carried out from an arbitrary shelf in the substrate cassette 1. The carriage roller 24 can be moved up and down relatively.
For this purpose, the cassette lifting mechanism 3 includes a bracket 31 that supports the bottom portion 11c of the substrate cassette 1, a ball screw that moves the bracket 31 up and down by servo drive, a guide 32 that guides the vertical movement of the bracket 31, and an upper and lower portion of the substrate cassette 1. And a sensor used for positioning in the direction.

搬送ローラユニット2は、搬送物であるガラス基板4の幅方向、言い換えればガラス基板の搬送方向と直交する方向に間隔をおいて対向配置された一対のベース21を備え、各ベース21には基板搬送方向に間隔をおいて複数(この実施例では4つ)のコンベヤフレーム22が固定されている。
コンベヤフレーム22には、ベアリング等の軸サポート23を介して搬送ローラ24が回転自在に支持されている。
The transport roller unit 2 includes a pair of bases 21 arranged to be opposed to each other in the width direction of the glass substrate 4 as a transported object, in other words, in a direction orthogonal to the transport direction of the glass substrate. A plurality of (four in this embodiment) conveyor frames 22 are fixed at intervals in the transport direction.
A conveyor roller 24 is rotatably supported on the conveyor frame 22 via a shaft support 23 such as a bearing.

この搬送ローラは24は、1つのコンベヤフレーム22につき、複数個(この実施例では6つ)が基板搬送方向に間隔をおいて並設されている。
搬送ローラ24の基端にはローラ駆動ギヤ25が設けられており、駆動モータ(図示略)からの回転駆動力はローラ駆動ギヤ25を介して搬送ローラ24に伝達される。
また、搬送ローラ24の基板カセット1内への抜き差しは、各コンベヤフレーム22を一体に固定しているベース21を水平方向、かつ基板搬送方向と直交する方向に前進及び後退させるローラ往復動機構(図示略)により実現される。
A plurality (six in this embodiment) of the transport rollers 24 are arranged in parallel in the substrate transport direction with respect to one conveyor frame 22.
A roller driving gear 25 is provided at the base end of the conveying roller 24, and rotational driving force from a driving motor (not shown) is transmitted to the conveying roller 24 via the roller driving gear 25.
The transport roller 24 is inserted into and removed from the substrate cassette 1 by reciprocating a roller reciprocating mechanism that moves the base 21 that integrally fixes each conveyor frame 22 forward and backward in the horizontal direction and in the direction perpendicular to the substrate transport direction ( (Not shown).

次に、以上の如く構成された基板保管搬送装置において、ガラス基板4を基板カセット1の任意の棚段に搬入する際の一手順について説明する。   Next, one procedure for carrying the glass substrate 4 into an arbitrary shelf of the substrate cassette 1 in the substrate storage / conveyance apparatus configured as described above will be described.

まず、カセット昇降機構3を駆動し、搬送ローラ24の前進移動先に、ガラス基板4を搬入しようとする棚段(以下、搬入予定段)が位置するように、基板カセット1を昇降させる。このとき、搬入予定段に対応する基板支持部12の上面12Aは、搬送ローラ24よりも若干低めに位置決めされる。
次いで、ローラ往復動機構を駆動し、搬送ローラ24を前進させて基板カセット1内に差し込む。このとき、コンベヤフレーム22に固定されたノズルは、搬入予定段に対応する基板支持部12aのカプラ15に連結される。
First, the cassette raising / lowering mechanism 3 is driven, and the substrate cassette 1 is raised and lowered so that a shelf stage (hereinafter referred to as a loading stage) where the glass substrate 4 is to be carried is positioned at the forward movement destination of the transport roller 24. At this time, the upper surface 12 </ b> A of the substrate support 12 corresponding to the planned carry-in stage is positioned slightly lower than the transport roller 24.
Next, the roller reciprocating mechanism is driven to advance the transport roller 24 and insert it into the substrate cassette 1. At this time, the nozzles fixed to the conveyor frame 22 are connected to the coupler 15 of the substrate support portion 12a corresponding to the planned carry-in stage.

そして、送気ブロワから管路,ノズルを経てカプラ15に圧搾空気を供給すると、この圧搾空気は、基板支持部12aと分配管16を通って他の基板支持部12とに分配され、搬入予定段に対応する各基板支持部12の吹出孔14から上方に向けて噴射される。
これにより、搬入されたガラス基板4と、基板支持部12の上面12Aとの間にエア浮上層を形成し得るようになり、搬入されたガラス基板4の下面中央部4c、すなわち、搬送ローラ24に支持される下両側縁部4a,4bを除く部分が、このエア浮上層を介して非接触に支持することが可能になる。
And if compressed air is supplied to the coupler 15 via a pipe line and a nozzle from an air supply blower, this compressed air will be distributed to the other board | substrate support part 12 through the board | substrate support part 12a and the distribution pipe 16, and will be carried in Injected upward from the blowout holes 14 of the substrate support portions 12 corresponding to the steps.
Thereby, an air floating layer can be formed between the glass substrate 4 carried in and the upper surface 12A of the substrate support portion 12, and the lower surface central portion 4c of the glass substrate 4 carried in, that is, the conveying roller 24. The portions excluding the lower side edges 4a and 4b supported by the air can be supported in a non-contact manner through the air floating layer.

しかる後、駆動モータを駆動し、その回転駆動力をローラ駆動ギヤ25を介して搬送ローラ24に伝達し、搬送ローラ24をその軸回りに回転させる。
すると、基板カセット1の上流側に移送されてきたガラス基板4は、その下面両側縁部4a,4bに対する搬送ローラ24との接触によって生じる摩擦力により、搬送方向前方に向かう搬送力を付与されて基板カセット1内に搬入される。このとき、ガラス基板4の下面両側縁部4a,4bは、それに転がり接触している搬送ローラ24によって下方より直接支持されている。
Thereafter, the drive motor is driven, the rotational driving force is transmitted to the transport roller 24 via the roller drive gear 25, and the transport roller 24 is rotated about its axis.
Then, the glass substrate 4 transferred to the upstream side of the substrate cassette 1 is given a conveying force toward the front in the conveying direction by the frictional force generated by the contact with the conveying rollers 24 with respect to the lower side edges 4a and 4b. It is carried into the substrate cassette 1. At this time, the lower surface side edges 4a and 4b of the glass substrate 4 are directly supported from below by the conveying roller 24 which is in rolling contact therewith.

これに対し、搬送ローラ24と下面両側縁部4a,4bとの接触部分を除くガラス基板4の下面中央部4cは、カプラ15を介して基板支持部12に供給された圧搾空気が吹出孔14より噴射されることにより、搬送ローラ24の頂部と、それよりも若干低めに位置決めされた基板支持部12の上面12Aとの段差に生ずる隙間に形成されたエア浮上層を介して、非接触に支持されている。
このように、基板カセット1への基板搬入中は、終始、ガラス基板4の下面中央部4cを基板支持部12から浮上させているので、ガラス基板4への接触は下面両側縁部4a,4bに対する搬送ローラ24だけとなり、基板汚染の極小化を図ることができる。
On the other hand, in the lower surface central portion 4c of the glass substrate 4 excluding the contact portion between the transport roller 24 and the lower surface side edges 4a and 4b, the compressed air supplied to the substrate support portion 12 via the coupler 15 is blown out. By being sprayed more, it is made non-contact through an air floating layer formed in a gap formed in a step between the top of the transport roller 24 and the upper surface 12A of the substrate support 12 positioned slightly lower than that. It is supported.
As described above, since the lower surface central portion 4c of the glass substrate 4 is floated from the substrate support portion 12 throughout the loading of the substrate into the substrate cassette 1, the lower surface side edges 4a and 4b are brought into contact with the glass substrate 4. Therefore, the contamination of the substrate can be minimized.

ガラス基板4が基板カセット1内に搬入されると、送気ブロワから基板支持部12への送気を遮断すると共に、カセット昇降機構3を駆動して基板カセット1を上昇させ、搬入されたガラス基板4の下面中央部4cを基板支持部12に預ける。
そして、ガラス基板4が搬送ローラ24から浮いたところで、つまり、ガラス基板4を基板支持部12に完全に預けたところで、ローラ往復動機構を駆動して搬送ローラ24を後退させ、搬送ローラ24を基板カセット1から抜き出す。以上で、搬入は終了する。
When the glass substrate 4 is carried into the substrate cassette 1, air supply from the air supply blower to the substrate support portion 12 is shut off, and the cassette lifting mechanism 3 is driven to raise the substrate cassette 1, and the glass that has been carried in The lower surface central portion 4 c of the substrate 4 is deposited on the substrate support portion 12.
When the glass substrate 4 is lifted from the transport roller 24, that is, when the glass substrate 4 is completely deposited on the substrate support portion 12, the roller reciprocating mechanism is driven to move the transport roller 24 backward, Pull out from the substrate cassette 1. This completes the carry-in.

次に、基板カセット1内に格納されている任意の棚段のガラス基板4を搬出する際の一手順について説明する。   Next, a procedure for carrying out an arbitrary shelf glass substrate 4 stored in the substrate cassette 1 will be described.

まず、カセット昇降機構3を駆動し、搬送ローラ24の前進移動先に、搬出しようとしているガラス基板4を格納している棚段(以下、搬出予定段)が位置するように、基板カセット1を昇降させる。このとき、搬出予定段に対応する基板支持部12の上面12Aは、搬送ローラ24よりも若干高めに位置決めされる。
次に、ローラ往復動機構を駆動し、搬送ローラ24を前進させて基板カセット1内に差し込んだ後、カセット昇降機構3を駆動し、基板カセット1を下降させて搬出予定のガラス基板4の下面両側縁部4a,4bを搬送ローラ24に預ける。
First, the cassette raising / lowering mechanism 3 is driven, and the substrate cassette 1 is set so that the shelf stage (hereinafter, the stage to be carried out) storing the glass substrate 4 to be carried out is positioned at the forward movement destination of the transport roller 24. Move up and down. At this time, the upper surface 12 </ b> A of the substrate support portion 12 corresponding to the planned carry-out stage is positioned slightly higher than the transport roller 24.
Next, the roller reciprocating mechanism is driven, the transport roller 24 is advanced and inserted into the substrate cassette 1, the cassette lifting mechanism 3 is driven, the substrate cassette 1 is lowered, and the lower surface of the glass substrate 4 to be carried out. The side edges 4 a and 4 b are deposited on the transport roller 24.

このとき、コンベヤフレーム22に固定されたノズルは、搬出予定段に対応する基板支持部12aのカプラ15に連結されている。よって、送気ブロワから管路,ノズルを経てカプラ15に圧搾空気を供給すると、この圧搾空気は、基板支持部12aと分配管16を通って他の基板支持部12とに分配され、搬出予定段に対応する各基板支持部12の吹出孔14から上方に向けて噴射される。
これにより、搬出予定のガラス基板4の下面中央部4cは、基板支持部12の上面12Aから浮上し、基板支持部12に非接触に支持されることになる。
At this time, the nozzle fixed to the conveyor frame 22 is connected to the coupler 15 of the substrate support portion 12a corresponding to the planned carry-out stage. Therefore, when compressed air is supplied from the air supply blower to the coupler 15 through the pipeline and nozzle, the compressed air is distributed to the other substrate support portion 12 through the substrate support portion 12a and the distribution pipe 16, and is scheduled to be carried out. Injected upward from the blowout holes 14 of the substrate support portions 12 corresponding to the steps.
Thereby, the lower surface center part 4c of the glass substrate 4 to be carried out floats from the upper surface 12A of the substrate support part 12 and is supported by the substrate support part 12 in a non-contact manner.

しかる後、駆動モータを駆動して搬送ローラ24をその軸回りに回転させると、基板カセット1内に格納されていた搬出予定のガラス基板4は、その下面両側縁部4a,4bに対する搬送ローラ24との接触によって生じる摩擦力により、搬送方向前方に向かう搬送力を付与されて基板カセット1外に搬出される。   Thereafter, when the drive motor is driven to rotate the transport roller 24 about its axis, the glass substrate 4 to be carried out stored in the substrate cassette 1 is transported to the lower side edges 4a and 4b. By the frictional force generated by the contact with the substrate, a conveyance force directed forward in the conveyance direction is applied and the substrate cassette 1 is carried out.

このとき、ガラス基板4の下面両側縁部4a,4bは、それに転がり接触している搬送ローラ24によって下方より直接支持されているが、その接触部分を除くガラス基板4の下面中央部4cは、エア浮上層を介して非接触に支持されている。
このように、基板カセット1からの基板搬出中は、終始、ガラス基板4の下面中央部4cを基板支持部12から浮上させているので、ガラス基板4への接触は下面両側縁部4a,4bに対する搬送ローラ24だけとなり、基板汚染の極小化を図ることができる。
At this time, the lower surface side edges 4a and 4b of the glass substrate 4 are directly supported from below by the conveying roller 24 which is in rolling contact therewith, but the lower surface central portion 4c of the glass substrate 4 excluding the contact portion is It is supported in a non-contact manner via an air floating layer.
Thus, since the lower surface central portion 4c of the glass substrate 4 is floated from the substrate supporting portion 12 throughout the substrate unloading from the substrate cassette 1, the lower surface side edges 4a and 4b are brought into contact with the glass substrate 4. Therefore, the contamination of the substrate can be minimized.

以上説明したように、本実施例による基板保管搬送装置によれば、ガラス基板4を搬入出したい棚段に搬送ローラ24を抜き差しできるよう、カセット昇降機構3を用いて基板カセット1と搬送ローラ24の高さ位置を合わせた後、搬送ローラ24を基板カセット1の外内へ水平方向に抜き差しすることにより、多関節ロボットを用いずとも、基板収納ピッチの狭い基板カセット1に対し、ガラス基板4を任意に搬入出することができる。   As described above, according to the substrate storage / conveyance device according to the present embodiment, the substrate cassette 1 and the conveyance roller 24 are used by using the cassette lifting / lowering mechanism 3 so that the conveyance roller 24 can be inserted / removed to / from the shelf where the glass substrate 4 is to be loaded / unloaded. After the height position is adjusted, the transfer roller 24 is inserted into and removed from the substrate cassette 1 in the horizontal direction, so that the glass substrate 4 can be moved relative to the substrate cassette 1 having a small substrate storage pitch without using an articulated robot. Can be carried in and out arbitrarily.

しかも、この搬入出中は、終始、ガラス基板4の下面中央部4cを基板支持部12からエア浮上させて非接触に支持しているので、ガラス基板4への接触は搬送ローラ24が差し込まれる下面両側縁部4a,4bだけとなり、基板汚染の極小化を図ることができる。
また、搬送ローラ24の基板カセット1への差し込み動作に伴い、搬入出したい棚段に対応する基板支持部12に対し、確実に圧搾空気を送気してガラス基板4の非接触支持を実現できると共に、この搬入出したい棚段に対応する基板支持部12のみに圧搾空気を送気し得るので、装置全体のコンパクト化も実現できる。
Moreover, during this loading / unloading, the lower surface central portion 4c of the glass substrate 4 is air-lifted from the substrate support portion 12 and supported in a non-contact manner, so that the transport roller 24 is inserted into the glass substrate 4 for contact. Only the bottom side edges 4a and 4b are provided, and the contamination of the substrate can be minimized.
Further, with the insertion operation of the transport roller 24 into the substrate cassette 1, the non-contact support of the glass substrate 4 can be realized by reliably supplying the compressed air to the substrate support portion 12 corresponding to the shelf to be loaded / unloaded. At the same time, since the compressed air can be supplied only to the substrate support portion 12 corresponding to the shelf to be carried in and out, the entire apparatus can be made compact.

なお、本発明は上記実施例に限定されるものではなく、その要旨を逸脱しない範囲で種々の設計変更が可能である。
例えば、基板搬入出手段は、搬送ローラ24のようなコンベヤ装置に代えて、ガラス基板4の両側縁部を把持するクランプと、そのクランプを基板搬送方向に移動させるスライド機構とを備えた外部駆動装置であってもよい。
In addition, this invention is not limited to the said Example, A various design change is possible in the range which does not deviate from the summary.
For example, the substrate carrying-in / out means is an external drive provided with a clamp that grips both side edges of the glass substrate 4 and a slide mechanism that moves the clamp in the substrate transport direction instead of the conveyor device such as the transport roller 24. It may be a device.

また、カプラ15は、1つの棚段に並ぶ2以上の基板支持部12に設けてもよい。この場合には、カプラ15のサイズと、各基板支持部12間の水平方向及び上下方向のピッチとに応じて、カプラ15を適宜間引いて配置することができる。
例えば、図3は、基板支持部12に対するカプラ15の一配置例を示す模式図であり、この図に示すように、水平方向及び上下方向に連設された基板支持部12に対し、1つおきにカプラ15を設けてもよい。
Further, the coupler 15 may be provided on two or more substrate support portions 12 arranged in one shelf. In this case, depending on the size of the coupler 15 and the horizontal and vertical pitches between the substrate support portions 12, the coupler 15 can be thinned and arranged as appropriate.
For example, FIG. 3 is a schematic diagram showing an example of the arrangement of the coupler 15 with respect to the substrate support unit 12. As shown in this figure, one coupler is provided for the substrate support unit 12 connected in the horizontal direction and the vertical direction. Another coupler 15 may be provided.

〔追加技術事項〕
さらに、上述した基板保管搬送装置を用いた基板搬入/搬出システムについて図4〜図6を参照して説明する。なお、以下の説明では、既に説明した構成要素と同一の構成要素については同一符号を付している。
[Additional technical matters]
Further, a substrate carry-in / carry-out system using the above-described substrate storage / conveyance device will be described with reference to FIGS. In the following description, the same components as those already described are denoted by the same reference numerals.

図4は、本基板搬入/搬出システムのシステム構成図である。本基板搬入/搬出システムは、AGV等の基板搬送装置とガラス基板4に所定のプロセス処理を施すプロセス装置との間に配置され、基板搬送装置によって搬送されてきた基板カセット1のプロセス装置への引渡し(基板搬入)とプロセス装置から回収した基板カセット1の基板搬送装置への引渡し(基板搬出)とを行う。本基板搬入/搬出システムは、図4に示すように、クレーンK、先入後出し装置F1,F2(基板供給装置)、基板保管搬送装置H1,H2及び移送装置Pから構成されている。これら各構成要素のうち、先入後出し装置F1及び基板保管搬送装置H1は基板搬入経路上に設けられ、一方、先入後出し装置F2及び基板保管搬送装置H2基板搬入経路上に設けられている。   FIG. 4 is a system configuration diagram of the substrate carrying-in / carrying-out system. This substrate loading / unloading system is arranged between a substrate transfer device such as AGV and a process device that performs a predetermined process on the glass substrate 4, and transfers the substrate cassette 1 that has been transferred by the substrate transfer device to the process device. Delivery (substrate carry-in) and delivery (substrate carry-out) of the substrate cassette 1 collected from the process apparatus to the substrate transfer apparatus are performed. As shown in FIG. 4, the substrate carry-in / carry-out system includes a crane K, first-in / last-out devices F 1 and F 2 (substrate supply devices), substrate storage and conveyance devices H 1 and H 2, and a transfer device P. Among these components, the first-in / out-out device F1 and the substrate storage / conveyance device H1 are provided on the substrate carry-in route, while the first-in / post-out device F2 and the substrate storage / conveyance device H2 are provided on the substrate carry-in route.

クレーンKは、基板搬送装置から引き取った基板カセット1を先入後出し装置F1に供給すると共に、先入後出し装置F2から回収した基板カセット1を基板搬送装置に引き渡す。クレーンKが先入後出し装置F1に供給する基板カセット1にはプロセス処理前のガラス基板4が収納され、一方、クレーンKが先入後出し装置F2から引き取った基板カセット1にはプロセス処理後のガラス基板4が収納されている。   The crane K supplies the substrate cassette 1 taken out from the substrate transfer device to the first-in / out-out device F1, and delivers the substrate cassette 1 collected from the first-in / out-out device F2 to the substrate transfer device. The substrate cassette 1 supplied by the crane K to the first-in / out-out apparatus F1 contains the glass substrate 4 before the processing, while the substrate cassette 1 taken out from the first-in / out-out apparatus F2 by the crane K has the processed glass. A substrate 4 is accommodated.

先入後出し装置F1は、基板カセット1に収納された複数のガラス基板4のうち、後から収納したものを先に基板保管搬送装置H1に払い出す。これに対して、基板保管搬送装置H1は、移送装置Pへのガラス基板4の払出に関するランダムアクセスバッファとして機能するものであり、先入後出し装置F1から供給されたガラス基板4を自らの基板カセット1に順次収納すると共に、当該基板カセット1に収納された複数のガラス基板4のうち、移送装置Pの要求に応じた任意のガラス基板4を移送装置Pに払い出す。移送装置Pは、レール上を移動することによってガラス基板4を移送する移送装置であり、基板保管搬送装置H1から供給されたガラス基板4をプロセス装置に移送すると共に、プロセス装置からガラス基板4(処理済)を回収して先入後出し装置F2に引き渡す。   The first-in / out-out device F1 pays out the one stored later among the plurality of glass substrates 4 stored in the substrate cassette 1 to the substrate storage / conveyance device H1 first. On the other hand, the substrate storage / conveyance device H1 functions as a random access buffer relating to the dispensing of the glass substrate 4 to the transfer device P, and the glass substrate 4 supplied from the first-in / last-out device F1 is used as its substrate cassette. The glass substrates 4 are sequentially stored in the substrate cassette 1, and among the plurality of glass substrates 4 stored in the substrate cassette 1, an arbitrary glass substrate 4 according to the request of the transfer device P is discharged to the transfer device P. The transfer device P is a transfer device that transfers the glass substrate 4 by moving on the rails. The transfer device P transfers the glass substrate 4 supplied from the substrate storage and transfer device H1 to the process device, and also transfers the glass substrate 4 ( Collected) and delivered to the first-in last-out device F2.

基板保管搬送装置H2は、先入後出し装置F2へのガラス基板4の払出に関するランダムアクセスバッファとして機能するものであり、移送装置Pから供給されたガラス基板4(処理済)を自らの基板カセット1に順次収納すると共に、当該基板カセット1に収納された複数のガラス基板4のうち、先入後出し装置F2の要求に応じた任意のガラス基板4を先入後出し装置F2に払い出す。先入後出し装置F2は、基板保管搬送装置H2から供給されたガラス基板4を自らの基板カセット1に順次収納する。   The substrate storage / conveyance device H2 functions as a random access buffer related to the dispensing of the glass substrate 4 to the first-in / last-out device F2, and the glass substrate 4 (processed) supplied from the transfer device P is used for its own substrate cassette 1. Are sequentially stored, and among the plurality of glass substrates 4 stored in the substrate cassette 1, any glass substrate 4 according to the request of the first-in / last-out device F2 is paid out to the first-in / out device F2. The first-in / after-out device F2 sequentially stores the glass substrates 4 supplied from the substrate storage / conveyance device H2 in its own substrate cassette 1.

図5は、このような本基板搬入/搬出システムにおける基板搬入フローを示す説明図である。上段イ)に示されるように、先入後出し装置F1の基板カセット1内に収納された複数のガラス基板4は、後に収納されたものから先に取り出されて基板保管搬送装置H1の基板カセット1に一時的にバッファリング(収納)され、移送装置Pまたはプロセス装置の要求に応じて当該基板保管搬送装置H1の基板カセット1に収納された任意のガラス基板4が移送装置Pを介してプロセス装置に供給される。   FIG. 5 is an explanatory diagram showing a substrate loading flow in such a substrate loading / unloading system. As shown in the upper row (a), the plurality of glass substrates 4 accommodated in the substrate cassette 1 of the first-in / out-out device F1 are taken out first from the ones stored later and the substrate cassette 1 of the substrate storage / conveyance device H1. The glass substrate 4 is temporarily buffered (stored), and an arbitrary glass substrate 4 stored in the substrate cassette 1 of the substrate storage and transfer apparatus H1 is transferred to the process apparatus via the transfer apparatus P according to the request of the transfer apparatus P or the process apparatus. To be supplied.

ここで、先入後出し装置F1が自らの基板カセット1内の全ガラス基板4を基板保管搬送装置H1に供給し終わると、中段ロ)に示されるように、先入後出し装置F1の空状態の基板カセット1はクレーンKによって除去されてガラス基板4が収納された基板カセット1に交換されるが、この交換の間においては、基板保管搬送装置H1は、自らの基板カセット1にバッファリングしたガラス基板4をプロセス装置に継続して供給する。そして、下段ハ)に示されるように、クレーンKによって先入後出し装置F1に次の基板カセット1が移載されると、先入後出し装置F1は基板保管搬送装置H1へのガラス基板4の供給を再開する。すなわち、基板保管搬送装置H1が存在することにより、先入後出し装置F1からのガラス基板4の供給が中断しても、プロセス装置へのガラス基板4の供給は途切れることなく連続的に行われる。   Here, when the first-in / last-out device F1 finishes supplying all the glass substrates 4 in its substrate cassette 1 to the substrate storage / conveying device H1, the empty state of the first-in / last-out device F1 becomes empty as shown in the middle row b). The substrate cassette 1 is removed by the crane K and replaced with the substrate cassette 1 in which the glass substrate 4 is accommodated. During this replacement, the substrate storage / conveying device H1 is buffered on its own substrate cassette 1. The substrate 4 is continuously supplied to the process apparatus. When the next substrate cassette 1 is transferred to the first-in / last-out device F1 by the crane K as shown in the lower section c), the first-in / out device F1 supplies the glass substrate 4 to the substrate storage / conveyance device H1. To resume. That is, since the substrate storage / conveyance device H1 exists, even if the supply of the glass substrate 4 from the first-in / last-out device F1 is interrupted, the supply of the glass substrate 4 to the process device is continuously performed without interruption.

図6は、このような本基板搬入/搬出システムにおける基板搬出フローを示す説明図である。最初に左側の基板搬出フロー(1)について説明すると、基板搬出時においては、上段イ)に示されるように、処理済のガラス基板4がプロセス装置から移送装置Pを介して基板保管搬送装置H2の基板カセット1内に順次収納される。そして、基板保管搬送装置H2は、自らの基板カセット1内のガラス基板4を先入後出し装置F2に順次供給する。   FIG. 6 is an explanatory diagram showing a substrate carry-out flow in the present substrate carry-in / out system. First, the left substrate unloading flow (1) will be described. When the substrate is unloaded, the processed glass substrate 4 is transferred from the process apparatus to the substrate storage / conveying apparatus H2 via the transfer apparatus P, as shown in the upper stage a). Are sequentially stored in the substrate cassette 1. Then, the substrate storage / conveyance device H2 sequentially supplies the glass substrates 4 in its substrate cassette 1 to the first-in / last-out device F2.

ここで、先入後出し装置F2の基板カセット1がガラス基板4で満杯になると、当該基板カセット1は、クレーンKによって除去されて空状態の基板カセット1に交換されるが、この交換の間も基板保管搬送装置H2はプロセス装置から回収されたガラス基板4の引取りを継続して行うので、プロセス装置からのガラス基板4の回収は途切れることなく連続的に行われる。   Here, when the substrate cassette 1 of the first-in / out-feed apparatus F2 is filled with the glass substrate 4, the substrate cassette 1 is removed by the crane K and replaced with an empty substrate cassette 1. Since the substrate storage / conveying apparatus H2 continuously takes the glass substrate 4 collected from the process apparatus, the collection of the glass substrate 4 from the process apparatus is continuously performed without interruption.

続いて、右側の基板搬出フロー(2)について説明する。
プロセス装置(例えば検査装置)から回収されて基板保管搬送装置H2の基板カセット1に収納されるガラス基板4には良品と不良品とがある。不良品はプロセス装置からランダムなタイミングで排出されるので、基板保管搬送装置H2の基板カセット1には良品と不良品とが無秩序に収納される。ここで、基板保管搬送装置H2は任意のガラス基板4を払い出すことができるので、上段イ)に示されるように良品のみを選択して先入後出し装置F2に供給し、不良品については一時的に保持する。そして、中段ロ)に示されるように、良品の払出が完了すると、不良品をまとめて先入後出し装置F2に供給する。そして、先入後出し装置F2内の基板カセット1が満杯となり交換されている間、基板保管搬送装置H2は、良品と不良品との収納を継続する。
Next, the right substrate carry-out flow (2) will be described.
The glass substrate 4 collected from the process apparatus (for example, an inspection apparatus) and stored in the substrate cassette 1 of the substrate storage / conveyance apparatus H2 includes a non-defective product and a defective product. Since defective products are discharged from the process apparatus at random timing, non-defective products and defective products are randomly stored in the substrate cassette 1 of the substrate storage / conveyance device H2. Here, since the substrate storage / conveying device H2 can pay out an arbitrary glass substrate 4, only a non-defective product is selected and supplied to the first-in / last-out device F2 as shown in the upper stage b), and the defective products are temporarily stored. Hold on. Then, as shown in the middle row (b), when the payout of the non-defective products is completed, the defective products are collectively supplied to the first-in / last-out device F2. Then, while the substrate cassette 1 in the first-in / out-out device F2 is full and replaced, the substrate storage / conveyance device H2 continues to store non-defective products and defective products.

このような基板搬入/搬出システムによれば、基板保管搬送装置H1,H2がガラス基板4を一時的に収納すると共に収納したガラス基板4を任意に払い出すランダムアクセスバッファとして機能するので、ガラス基板4の連続的な搬入及び搬出を実現できると共に、良品と不良品とを分別して排出することができる。   According to such a substrate loading / unloading system, since the substrate storage / conveying devices H1 and H2 temporarily store the glass substrate 4 and function as a random access buffer for arbitrarily discharging the stored glass substrate 4, the glass substrate 4 can be carried in and out continuously, and good products and defective products can be separated and discharged.

なお、必要に応じて基板保管搬送装置H1,H2の何れか一方のみを設けるようにしても良い。また、上記基板搬入/搬出システムでは基板供給装置として先入後出し装置F1,F2を用いたが、基板供給装置は先入後出し装置F1,F2に限定されない。基板保管搬送装置H1,H2と同等のものを基板供給装置として用いても良い。 Note that only one of the substrate storage and transfer devices H1 and H2 may be provided as necessary. In the substrate carry-in / carry-out system, first-in / last-out devices F1, F2 are used as substrate supply devices, but the substrate supply device is not limited to the first-in / out devices F1, F2. Equivalent to the substrate storage / conveyance devices H1 and H2 may be used as the substrate supply device.
