Description

【0001】
【発明の属する技術分野】
本発明は、電子部品が実装されるプリント基板を搬送する基板搬送装置、およびこの装置を備えた電子部品実装装置に関する。
【0002】
【従来の技術】
この種の基板搬送装置として、図10に示すように、基板を2列平行に並べて搬送するタイプのものが知られている。この基板搬送装置Aは、基台上に一対のガイドレール1,2および3,4を互いに平行かつ水平にそれぞれ並設し、このガイドレール対1,2および3,4により案内される基板Sを支持して搬送する一対のコンベアベルトを各ガイドレールにそれぞれ平行に並設して構成した搬送装置5,6を2列並設したものである。中央に配置された各ガイドレール2,3を装架し各コンベアベルトを張架する基準支持部材は基台上の基準位置に位置決め固定され、両側に配置された各ガイドレール1,4を装架し各コンベアベルトをそれぞれ張架する2つの可動支持部材はそれぞれガイドレールの長手方向と直交する方向に位置調整可能に基台に取り付けられている。また、両可動支持部材は中央に配置された基準ガイドレール2,3に対して同期して同距離となるように移動されるものである。
【0003】
また、基板Sに装着される部品を供給する部品供給装置Bを上述した基板搬送装置Aの一側にのみ設けた電子部品実装装置も知られている。このとき、部品供給装置Bは基台の所定位置すなわち両側に配置されたガイドレール1を最大に開いた位置aに隣接した位置に固定されている。
【0004】
【発明が解決しようとする課題】
上述した基板搬送装置Aにおいては、搬送装置5,6の搬送幅(すなわち互いに対向するガイドレール間の幅)を搬送する基板の幅に応じて設定する際には、可動支持部材をガイドレールの長手方向と直交する方向に移動させることにより、両側に配置された各ガイドレール1,4は基準ガイドレール2,3から同距離だけ離れた位置に移動されるので、搬送装置5,6の各ガイドレール対1,2および3,4は常に同じ幅に設定される。したがって、この基板搬送装置Aは同じ幅の基板を2列平行に並べて搬送することとなる。これに対して異なる幅の基板を2列または3列以上平行に並べて搬送する基板搬送装置が要請されている。
【0005】
また上述した基板搬送装置Aにおいては、中央に配置された各ガイドレール2,3を基準にして両側に配置された各ガイドレール1,4を基準ガイドレール2,3から同距離だけ離れた位置に移動させるので、基板搬送装置が搬送できる基板の最大幅は基板搬送装置のガイドレールの長手方向と直交する方向の幅の略半分となる。したがって、幅の広い基板を搬送するためには、基板搬送装置Aの幅を広げることとなるが、基板搬送装置Aが大型化するという問題が生じる。
【0006】
また上述した電子部品実装装置においては、搬送可能な最大幅より十分小さい幅(例えば最大幅の半分)の基板を搬送する際には、両側に配置された各ガイドレール1,4は基準ガイドレール2,3から基板幅だけ離れた位置すなわち基台の所定位置に固定された部品供給装置Bから遠く離れた位置(例えば最大幅の半分だけ離れた位置)に位置決め固定されるので、スループットが悪化するという問題があった。
【0007】
そこで、本発明は、上述した各問題を解消するためになされたもので、基板搬送装置の一端に配置したガイドレールおよびコンベアベルトを位置決め固定するとともに他のガイドレールおよびコンベアベルトをガイドレールの長手方向と直交する方向に位置調整可能に取り付けることにより、1又は2以上の基板を平行に並べて搬送する基板搬送装置を効率よく使用することを目的とする。
【0008】

【0015】
【発明の作用・効果】
上記のように構成した請求項1に係る発明において、搬送装置の搬送幅を搬送する基板の幅に応じて設定する際には、基準位置に位置決め固定した基準支持部材を基準にして他端可動支持部材および各中間可動支持部材をそれぞれ所定の位置に位置調整して固定する。これにより、基準支持部材とこの基準支持部材に隣接する中間可動支持部材、他端可動支持部材とこの他端可動支持部材に隣接する中間可動支持部材、ならびに基準支持部材および他端可動支持部材にそれぞれ隣接する中間可動支持部材とは別の中間可動支持部材であって互いに隣接する各中間可動支持部材にそれぞれ対向させて装架したガイドレール対の各幅は搬送される基板の幅に応じてそれぞれ設定される。したがって、基板搬送装置は異なる幅の基板を2列または3列以上平行に並べて搬送することができるので、基板搬送装置を大型化することなく効率よく基板を搬送することができる。
さらに、各支持部材駆動装置が対応する各可動支持部材を独立して自動的に所望位置に移動させることができる。
【0016】
上記のように構成した請求項2に係る発明においては、モータにより各回転軸が回転すると、回転軸に係合した各プーリ対が同期して回転して各搬送装置のコンベアベルト対が互いに独立して同期駆動される。したがって、各搬送装置において基板の搬送を個々に制御することができる。また、位置決め固定された基準支持部材と他端固定支持部材に各回転軸がそれぞれ軸架されているので、回転軸を確実に支承することができる。
【0017】
上記のように構成した請求項3に係る発明においては、搬送装置の搬送幅を搬送する基板の幅に応じて設定する際には、基準位置に位置決め固定した基準支持部材を基準にして他端可動支持部材と第1および第2中間可動支持部材をそれぞれ所定の位置に位置調整して固定する。これにより、基準支持部材と第1中間可動支持部材、および他端可動支持部材と第2中間可動支持部材にそれぞれ対向させて装架したガイドレール対の各幅は搬送される基板の幅に応じてそれぞれ設定される。したがって、基板搬送装置は異なる幅の基板を2列平行に並べて搬送することができるので、基板搬送装置を大型化することなく効率よく基板を搬送することができる。
さらに、各支持部材駆動装置が対応する各可動支持部材を独立して自動的に所望位置に移動させることができる。
【0018】
上記のように構成した請求項4に係る発明において、モータにより2つの回転軸が回転されると、回転軸に係合した各プーリ対が同期して回転して各搬送装置のコンベアベルト対が互いに独立して同期駆動される。したがって、各搬送装置において基板の搬送を個々に制御することができる。また、位置決め固定された基準支持部材と他端固定支持部材に各回転軸がそれぞれ軸架されているので、回転軸を確実に支承することができる。
【0019】
上記のように構成した請求項5に係る発明においては、搬送装置の搬送幅を基板幅に合わせて変更する際に、位置決めされる中間可動部材の数を少なくしたので、位置決め工数を少なくすることができる。また、中間可動部材を自動的に移動させる場合には、位置決めされる中間可動部材の数を少なくしたので、中間可動部材を移動させる駆動構造を簡単にすることができる。
【0020】
上記のように構成した請求項6に係る発明において、他端可動支持部材および中間可動支持部材は基台上にガイドレールの長手方向と直交する方向に延ばして配設した支持部材用レール上を支持部材駆動装置によりそれぞれ移動されるようになっているので、他端可動支持部材および中間可動支持部材にそれぞれ設けたガイドレール対およびコンベアベルト対を自動的に所定の位置まで移動させることができる。

【0034】

【0037】
また、第3左支持フレームの側壁にも、第4駆動用プーリ88と同様に搬送用回転軸28に係合して回転される第3駆動用プーリ78が回転可能に支承され、この第3駆動用プーリ78には第3コンベアベルト72が張架されている。これにより、第3および第4駆動用プーリ78,88が同期回転するので、第3および第4コンベアベルト72,82は同期駆動される。なお、この第3コンベアベルト72は第3取付フレーム73および第3左右支持フレーム74,75の各側壁に回転可能に支承された各プーリ79に張架されている。

部品供給装置30は、主として図1および図7に示すように、基枠10上に複数のカセット式フィーダ31を並設して構成したものである。カセット式フィーダ31は、基枠10に離脱可能に取り付けた本体32と、本体32の後部に設けた供給リール33と、本体32の先端に設けた部品取出部34を備えている。供給リール33には電子部品Pが所定ピッチで封入された細長いテープ(図示省略)が巻回保持され、このテープがスプロケット(図示省略)により所定ピッチで引き出され、電子部品Pが封入状態を解除されて部品取出部34に順次送り込まれる。なお、部品供給装置30と基板搬送装置20の間には監視カメラ35が設けられており、この監視カメラ35により装着ヘッド46に設けた吸着ノズル48に吸着された電子部品Pの状態をモニターする。
【0041】
部品装着装置40は、主として図1に示すように、XYロボットタイプのものであり、基枠10上に装架されて基板搬送装置20および部品供給装置30の上方に配設されY軸サーボモータ42によりY方向に移動されるY方向移動スライダ41を備えている。このY方向移動スライダ41には、X軸サーボモータ(図示省略)によりY方向に直交する水平なX方向に移動されるX方向移動スライダ43が備えられている。
【0042】
X方向移動スライダ43には、図6に示すように、電子部品Pを吸着して基板Sに実装する吸着ノズル44を設けた実装ヘッド45が取り付けられている。この実装ヘッド45はX方向移動スライダ43に取り付けられたヘッドフレーム46を備えている。ヘッドフレーム46の下部には、複数(例えば8本)の吸着ノズル44を上下方向(Z軸方向)に上向きに負勢されて往復動可能に保持する円筒状のノズルホルダ47が軸線まわりに回転可能に取り付けられている。このノズルホルダ47はヘッドフレーム46に取り付けたR軸モータ48によって吸着ノズル44が所定位置で停止するように間欠的に回転される。所定位置のうち電子部品Pを実装する実装ポイント(実装ステーション)に停止した吸着ノズル44はZ軸モータ49に駆動されるZ軸送りねじ49aによって上下動される。各吸着ノズル44は、開閉弁を設けた管路を介して負圧供給源に接続されている(何れも図示省略)。吸着ノズル44は電子部品Pの種類により切換選択するようにしている。なお、吸着ノズル44を複数個でなく1個だけ設けるようにしてもよい。
【0043】
次に上述した実施の形態において、搬送する基板Sの幅に合わせて第1および第2搬送装置21,22のガイドレール幅の設定をそれぞれ変更する際には、基準位置に位置決め固定した基準支持部材50を基準にして他端可動支持部材80、第1および第2中間可動支持部材60,70をそれぞれ所定の位置に位置調整して固定する。具体的には、最初に、第1搬送装置21で搬送される予定の基板幅に応じて第1の中間可動支持部材60の位置を調整して固定し、次に、固定された第1の中間可動支持部材60と支持フレーム91との間の範囲で、第2の中間可動支持部材70と他端可動支持部材80との位置を、それらの間隔が第2搬送装置22で搬送される予定の基板幅となるように調整して固定するのが望ましい。
【0044】
これにより、基準支持部材50とこの基準支持部材50に隣接する第1中間可動支持部材60、他端可動支持部材80とこの他端可動支持部材80に隣接する第2中間可動支持部材70をそれぞれ対向させて装架したガイドレール対51,61,71,81の各幅は搬送される基板Sの幅に応じてそれぞれ設定される。したがって、基板搬送装置20は同一幅の基板だけでなく異なる幅の基板をも2列平行に並べて搬送することができるので、基板搬送装置ひいては電子部品実装装置を大型化することなく効率よく基板を搬送することができる。
【0045】
また、上述した他端可動支持部材80、第1および第2中間可動支持部材60,70をそれぞれ所定の位置に位置調整して固定する際には、支持部材駆動装置により各可動支持部材60,70,80がそれぞれ移動されるようにしたので、他端可動支持部材80および第1および第2中間可動支持部材60,70にそれぞれ設けたガイドレール61,71,81およびコンベアベルト62,72,82を自動的に所定の位置まで移動させることができる。
【0046】
なお、他端可動支持部材80、第1および第2中間可動支持部材60,70を位置調整して、図8に示す位置にガイドレール61,71,81を配置するようにしてもよい。これによれば基板搬送装置20が搬送できる基板Sの最大幅は基板搬送装置20のガイドレールの長手方向と直交する方向の幅とほぼ同じ長さとなる。したがって、基板搬送装置を前記直交する方向に拡張しなくても幅の広い基板を搬送することができる。
【0047】
また、他端可動支持部材80、第1および第2中間可動支持部材60,70を位置調整して、図9に示す位置にガイドレール61,71,81を配置するようにしてもよい。これによれば、基板搬送装置の両側に部品供給装置を配置して両部品供給装置から電子部品を供給可能ないわゆるダブルデバイス形式の場合において、搬送可能な最大幅より十分小さい幅(例えば最大幅の半分)の基板を搬送する際には、両側に配置された第1および第4ガイドレール51,81は部品供給装置から最短の位置に配置されるので、部品装着装置のスループットが悪化するのを防ぐことができる。
【0048】
また、基板搬送装置20の一端側に基板Sに装着される電子部品Pを供給する部品供給装置30を設けたため、部品供給装置30が基準支持部材50に装架されて所定の基準位置に固定された基準ガイドレール51に隣接して設けられているので、一端側のガイドレール対51,61の幅を変更しても部品供給装置30から基準ガイドレール51までの距離は変わらない。一方、従来は部品供給装置30に隣接するガイドレールを移動させてガイドレール対の幅を変更していたので、一端側のガイドレール対の幅を変更すると部品供給装置30から隣接するガイドレールまでの距離が異なっていた。したがって、搬送する基板Sの幅が搬送可能な最大幅より小さければ小さいほど部品供給装置30から基板Sまでの最短距離は従来に比べて短く抑えることができるので、電子部品実装装置のスループットを向上させることができる。
【0049】
なお、上記実施の形態においては、搬送用回転軸28を一本だけでなく、複数列並べて設けた搬送路(搬送装置)と同じ数の搬送用回転軸28を設けて、これら搬送用回転軸28を別々に回転させ、各搬送路のコンベアベルト対を個々独立に駆動するようにしてもよい。これによれば、駆動用モータにより各回転軸が回転すると、回転軸にそれぞれ係合した各駆動用プーリ対が同期して回転して各搬送装置のコンベアベルト対が互いに独立して同期駆動される。したがって、各搬送装置において基板の搬送を個々に制御することができる。また、位置決め固定された基準支持部材と他端固定支持部材に各回転軸がそれぞれ軸架されているので、回転軸を確実に支承することができる。
【0050】
また、上記実施の形態においては、搬送路を2本設けたが、搬送路を3本以上設けるようにしてもよい。この場合、第1および第2中間可動支持部材60,70の間に1対以上の中間可動支持部材をさらに設け、これら中間可動支持部材に一対のガイドレールおよびコンベアベルトを対向させてそれぞれ設けるようにすればよい。これによれば、搬送装置の搬送幅を搬送する基板の幅に応じて設定する際には、基準位置に位置決め固定した基準支持部材50を基準にして他端可動支持部材80および各中間可動支持部材をそれぞれ所定の位置に位置調整して固定する。これにより、基準支持部材50とこの基準支持部材50に隣接する第1中間可動支持部材60、他端可動支持部材80とこの他端可動支持部材80に隣接する第2中間可動支持部材70、および互いに隣接する各中間可動支持部材にそれぞれ対向させて装架したガイドレール対の各幅は搬送される基板の幅に応じてそれぞれ設定される。したがって、基板搬送装置は異なる幅の基板を2列または3列以上平行に並べて搬送することができるので、基板搬送装置を大型化することなく効率よく基板を搬送することができる。
【0051】
また、上記実施の形態においては、互いに隣接する中間可動支持部材であって互いに異なるガイドレール対を構成するガイドレールをそれぞれ装架したもの(例えば、第1および第2中間可動支持部材60,70)をそれぞれ別体に形成して別々に移動させるようにしたが、これら互いに隣接する中間可動支持部材を一体的に構成して同時に移動させるようにしてもよい。
【0052】
この態様において、搬送する基板Sの幅に合わせて第1および第2搬送装置21,22のガイドレール幅の設定をそれぞれ変更する場合には、最初に、第1搬送装置21で搬送される予定の基板幅に応じて第1および第2中間可動支持部材60,70の一体ものの位置を調整して固定し、次に、固定された第2中間可動支持部材70の位置を基準に第2搬送装置22で搬送される予定の基板幅に応じて他端可動支持部材80の位置を位置決めして固定するのが望ましい。
【0053】
これによれば、搬送装置21(または22)の搬送幅を基板幅に合わせて変更する際に、位置決めされる中間可動部材の数を少なくしたので、位置決め工数を少なくすることができる。また、中間可動部材を自動的に移動させる場合には、位置決めされる中間可動部材の数を少なくしたので、中間可動部材を移動させる駆動構造を簡単にすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a board carrying device for carrying a printed circuit board on which electronic components are mounted, and an electronic component mounting apparatus provided with this device.
[0002]
[Prior art]
As this type of substrate transport apparatus, as shown in FIG. 10, there is known a type that transports substrates arranged in parallel in two rows. In this substrate transport apparatus A, a pair of guide rails 1, 2 and 3, 4 are arranged in parallel and horizontally on a base, and a substrate S guided by the guide rail pairs 1, 2, 3 and 4 is provided. The conveying devices 5 and 6 are arranged in parallel, each of which is configured by arranging a pair of conveyor belts that support and convey the belt in parallel with the guide rails. The reference support member that mounts the guide rails 2 and 3 arranged in the center and stretches the conveyor belt is positioned and fixed at the reference position on the base, and the guide rails 1 and 4 arranged on both sides are mounted. The two movable support members that stretch the respective conveyor belts are attached to the base so that their positions can be adjusted in the direction perpendicular to the longitudinal direction of the guide rail. Both movable support members are moved so as to have the same distance in synchronization with the reference guide rails 2 and 3 arranged at the center.
[0003]
There is also known an electronic component mounting apparatus in which a component supply device B that supplies components to be mounted on the substrate S is provided only on one side of the substrate transfer device A described above. At this time, the component supply device B is fixed to a predetermined position of the base, that is, a position adjacent to the position a where the guide rails 1 arranged on both sides are opened to the maximum.
[0004]
[Problems to be solved by the invention]
In the substrate transport apparatus A described above, when setting the transport width of the transport apparatuses 5 and 6 (that is, the width between the guide rails facing each other) according to the width of the substrate to be transported, the movable support member is mounted on the guide rail. By moving in the direction orthogonal to the longitudinal direction, the guide rails 1 and 4 arranged on both sides are moved to the positions separated from the reference guide rails 2 and 3 by the same distance. The guide rail pairs 1, 2 and 3, 4 are always set to the same width. Therefore, the substrate transport apparatus A transports substrates having the same width in parallel in two rows. On the other hand, there is a demand for a substrate transport apparatus that transports substrates having different widths in parallel by arranging two or more rows in parallel.
[0005]
In the above-described substrate transfer apparatus A, the guide rails 1 and 4 arranged on both sides with respect to the guide rails 2 and 3 arranged at the center are located away from the reference guide rails 2 and 3 by the same distance. Therefore, the maximum width of the substrate that can be transported by the substrate transport device is approximately half of the width in the direction orthogonal to the longitudinal direction of the guide rail of the substrate transport device. Therefore, in order to transfer a wide substrate, the width of the substrate transfer device A is increased, but there is a problem that the substrate transfer device A is enlarged.
[0006]
In the electronic component mounting apparatus described above, when transporting a board having a width sufficiently smaller than the maximum transportable width (for example, half of the maximum width), the guide rails 1 and 4 arranged on both sides are the reference guide rails. Throughput is deteriorated because the position is fixed at a position away from the component supply device B fixed at a predetermined position of the base, ie, a position far from the component supply device B fixed at a predetermined position of the base (for example, a position separated by half of the maximum width). There was a problem to do.
[0007]
Accordingly, the present invention has been made to solve the above-described problems. The guide rail and the conveyor belt disposed at one end of the substrate transport apparatus are positioned and fixed, and the other guide rail and the conveyor belt are disposed in the longitudinal direction of the guide rail. An object is to efficiently use a substrate transport apparatus that transports one or two or more substrates arranged in parallel by attaching them so that the position can be adjusted in a direction orthogonal to the direction.

[0043]
Next, in the above-described embodiment, when changing the setting of the guide rail widths of the first and second transport devices 21 and 22 in accordance with the width of the substrate S to be transported, the reference support is positioned and fixed at the reference position. The other end movable support member 80 and the first and second intermediate movable support members 60 and 70 are respectively adjusted to positions at predetermined positions and fixed with the member 50 as a reference. Specifically, first, the position of the first intermediate movable support member 60 is adjusted and fixed in accordance with the width of the substrate scheduled to be transferred by the first transfer device 21, and then the fixed first Within the range between the intermediate movable support member 60 and the support frame 91, the positions of the second intermediate movable support member 70 and the other end movable support member 80 are scheduled to be transported by the second transport device 22. It is desirable to adjust and fix so that the substrate width becomes the same.
[0044]
As a result, the reference support member 50, the first intermediate movable support member 60 adjacent to the reference support member 50, the other end movable support member 80, and the second intermediate movable support member 70 adjacent to the other end movable support member 80, respectively. The widths of the pair of guide rails 51, 61, 71, 81 mounted facing each other are set according to the width of the substrate S to be transported. Therefore, the substrate transport device 20 can transport not only the same width substrate but also different width substrates in parallel in two rows, so that the substrate can be efficiently transferred without increasing the size of the substrate transport device and thus the electronic component mounting device. Can be transported.
[0045]
Further, when the other end movable support member 80 and the first and second intermediate movable support members 60 and 70 are fixed at predetermined positions, the movable support members 60, 70, 80 are respectively moved, so that the guide rails 61, 71, 81 and the conveyor belts 62, 72, provided on the other end movable support member 80 and the first and second intermediate movable support members 60, 70, respectively, are provided. 82 can be automatically moved to a predetermined position.
[0046]
The other end movable support member 80 and the first and second intermediate movable support members 60 and 70 may be adjusted so that the guide rails 61, 71, and 81 are disposed at the positions shown in FIG. According to this, the maximum width of the substrate S that can be transported by the substrate transport apparatus 20 is substantially the same as the width in the direction orthogonal to the longitudinal direction of the guide rail of the substrate transport apparatus 20. Therefore, a wide substrate can be transported without expanding the substrate transport device in the orthogonal direction.
[0047]
Further, the position of the other end movable support member 80 and the first and second intermediate movable support members 60, 70 may be adjusted, and the guide rails 61, 71, 81 may be disposed at the positions shown in FIG. According to this, in the case of a so-called double device type in which component supply devices are arranged on both sides of the substrate transfer device and electronic components can be supplied from both component supply devices, the width is sufficiently smaller than the maximum transferable width (for example, the maximum width). When transporting half of the board), the first and fourth guide rails 51 and 81 disposed on both sides are disposed at the shortest position from the component supply device, which deteriorates the throughput of the component mounting device. Can be prevented.
[0048]
In addition, since the component supply device 30 for supplying the electronic component P to be mounted on the substrate S is provided on one end side of the substrate transport device 20, the component supply device 30 is mounted on the reference support member 50 and fixed at a predetermined reference position. Since the guide rail 51 is provided adjacent to the reference guide rail 51, the distance from the component supply device 30 to the reference guide rail 51 does not change even if the width of the guide rail pair 51, 61 on one end side is changed. On the other hand, conventionally, the guide rail adjacent to the component supply device 30 is moved to change the width of the pair of guide rails. Therefore, if the width of the guide rail pair on one end side is changed, the component supply device 30 moves to the adjacent guide rail. The distance was different. Accordingly, the shorter the width of the substrate S to be transferred is smaller than the maximum transferable width, the shorter the shortest distance from the component supply device 30 to the substrate S can be reduced compared to the conventional case, thereby improving the throughput of the electronic component mounting apparatus. Can be made.
[0049]

According to this, when each rotating shaft is rotated by the driving motor, each driving pulley pair engaged with each rotating shaft rotates in synchronization, and the conveyor belt pair of each conveying device is driven synchronously independently of each other. The Therefore, it is possible to individually control the conveyance of the substrate in each conveyance device. In addition, since each rotation shaft is mounted on the reference support member and the other end fixed support member that are positioned and fixed, the rotation shaft can be reliably supported.
[0050]
In the above embodiment, two transport paths are provided, but three or more transport paths may be provided. In this case, one or more pairs of intermediate movable support members are further provided between the first and second intermediate movable support members 60, 70, and a pair of guide rails and a conveyor belt are provided opposite to each other. You can do it. According to this, when setting the transport width of the transport device according to the width of the substrate to be transported, the other end movable support member 80 and each intermediate movable support with reference to the reference support member 50 positioned and fixed at the reference position. Each member is fixed at a predetermined position. Thus, the reference support member 50, the first intermediate movable support member 60 adjacent to the reference support member 50, the other end movable support member 80, the second intermediate movable support member 70 adjacent to the other end movable support member 80, and Each width of the pair of guide rails mounted so as to oppose each adjacent intermediate movable support member is set according to the width of the substrate to be transported. Therefore, the substrate transfer apparatus can transfer two or more rows of substrates having different widths in parallel, so that the substrate can be transferred efficiently without increasing the size of the substrate transfer apparatus.
[0051]
Further, in the above-described embodiment, the intermediate movable support members adjacent to each other and mounted with guide rails constituting different guide rail pairs (for example, the first and second intermediate movable support members 60 and 70). ) Are formed separately and moved separately, but these intermediate movable support members adjacent to each other may be integrally formed and moved simultaneously.
[0052]
In this aspect, when the setting of the guide rail width of the first and second transport devices 21 and 22 is changed in accordance with the width of the substrate S to be transported, the first transport device 21 is scheduled to transport first. The position of the first and second intermediate movable support members 60 and 70 is adjusted and fixed in accordance with the width of the substrate, and then the second transport is performed based on the position of the fixed second intermediate movable support member 70. It is desirable to position and fix the position of the other end movable support member 80 in accordance with the width of the substrate to be transported by the apparatus 22.
[0053]
According to this, when the conveyance width of the conveyance device 21 (or 22) is changed in accordance with the substrate width, the number of intermediate movable members to be positioned is reduced, so that the number of positioning steps can be reduced. Further, when the intermediate movable member is automatically moved, the number of intermediate movable members to be positioned is reduced, so that the drive structure for moving the intermediate movable member can be simplified.
