Abstract

A flat-plate conveying device (1) that conveys glass substrates (flat plates; G) to predetermined positions on a production line (L) includes a plurality of rotatable conveying shafts (7) disposed in a direction along which the glass substrates (G) travel with a predetermined gap interposed therebetween and a plurality of conveying rollers (8) rotatably attached to the rotatable conveying shafts (7) so as to be brought into contact with the rear surfaces of the glass substrates (G). A plurality of rotatable aligning shafts (9, 10, 11) are disposed before a second glass-sorting device (6), and pairs of opposing guide rollers (13, 14, 15) having outside diameters larger than that of the conveying rollers (8) are provided for the rotatable aligning shafts at outer positions in the axial direction. The gaps between the largest diameter portions of the guide rollers (13, 14, 15) are gradually reduced in the traveling direction of the glass substrates (G) (L1 > L2 > L3), and the gaps between the guide rollers (13, 14, 15) can be changed in accordance with the width of the glass substrates (G). With this structure, flat plates having different sizes can travel on the same production line such that the straightness of travel of the flat plates is kept while contact with the side surfaces or the front surfaces of the flat plates is avoided as much as possible.

Description

平板搬送装置Flat plate conveyor
　本発明は、液晶ディスプレイに使用するガラス基板などの平板を搬送する平板搬送装置に関し、特にその平板の直進性を改善するものである。 The present invention relates to a flat plate transport device for transporting a flat plate such as a glass substrate used in a liquid crystal display, and particularly to improve the straightness of the flat plate.
　従来より、製造ライン上でガラス基板などの平板を搬送する平板搬送装置は知られている。例えば、特許文献１の平板搬送装置は、基板に接触しない部位に設けられた搬送ローラーシャフト固定部位が分割式である基板搬送用ローラーを備え、基板に影響を及ぼすことなく安定した搬送が得られるようにしている。 Conventionally, a flat plate conveying apparatus for conveying a flat plate such as a glass substrate on a production line is known. For example, the flat plate conveyance device of Patent Document 1 includes a substrate conveyance roller in which a conveyance roller shaft fixing portion provided in a portion that does not contact the substrate is divided, and stable conveyance can be obtained without affecting the substrate. I am doing so.
特開２００６－８９１４８号公報JP 2006-89148 A
　しかしながら、上記特許文献１の平板搬送装置では、軸方向外側に配置されたローラーの外周から延びるリブを、頻繁に基板の側面に当接させて基板の位置決め（センタリング）をしているので、製造ラインが長距離になればなるほど、基板側面が損傷しやすいという問題があった。 However, in the flat plate conveying device of the above-mentioned Patent Document 1, since the rib extending from the outer periphery of the roller arranged on the outer side in the axial direction is frequently brought into contact with the side surface of the substrate, the substrate is positioned (centering). There was a problem that the longer the line was, the easier the side of the substrate was damaged.
　また、１つの製造ラインには、通常複数のサイズの基板が流れる可能性があり、すべてのサイズの基板に対して直進性を確保するのは困難である。 Moreover, there is a possibility that a plurality of substrates usually flow in one production line, and it is difficult to ensure straightness with respect to substrates of all sizes.
　本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、同じ製造ラインで、異なるサイズの平板をできるだけ平板の側面や表面に接触することなく、平板の直進性を保ちながら流せるようにすることにある。 The present invention has been made in view of the above points, and the object of the present invention is to maintain the straightness of the flat plate in the same production line without contacting the flat plate of different sizes as much as possible with the side surface or the surface of the flat plate. It is to be able to flow while.
　上記の目的を達成するために、この発明では、搬送ラインの所定位置に徐々に狭くなるように設けた、平板を搬送ラインの進行方向に沿って真っ直ぐ進むように押し戻すガイドローラーの幅を平板の幅に合わせて変更可能にした。 In order to achieve the above object, according to the present invention, the width of the guide roller, which is provided so as to be gradually narrowed at a predetermined position on the transport line and pushes back the flat plate so as to advance straight along the traveling direction of the transport line, Changeable to fit the width.
　具体的には、第１の発明では、製造ライン上の各ポジションに平板を搬送する平板搬送装置を前提とし、
　上記平板搬送装置は、
　上記平板の進行方向に所定の間隔をあけて配置された複数の回転軸と、
　上記各回転軸に回転自在に配置され、上記平板の裏面側に当接する複数の搬送用ローラーとを備え、
　上記各ポジションの手前における上記複数の回転軸には、該回転軸の軸方向外側に上記搬送用ローラーよりも外径の大きいガイドローラーがそれぞれ設けられ、各回転軸の対向するガイドローラーの最大径部分間の間隔は、上記平板の幅よりも大きく、進行方向に向かって徐々に狭くなっており、
　上記ガイドローラーの間隔は、上記平板の幅に合わせて変更可能に構成されている。 Specifically, in the first invention, on the premise of a flat plate transport device that transports a flat plate to each position on the production line,
The flat plate conveying device is
A plurality of rotating shafts arranged at predetermined intervals in the traveling direction of the flat plate;
A plurality of transport rollers that are rotatably arranged on each of the rotation shafts and abut on the back side of the flat plate;
The plurality of rotating shafts in front of each position are each provided with a guide roller having an outer diameter larger than that of the conveying roller on the outer side in the axial direction of the rotating shaft, and the maximum diameter of the guide rollers facing each rotating shaft. The interval between the parts is larger than the width of the flat plate and gradually narrows in the traveling direction,
The space | interval of the said guide roller is comprised so that a change is possible according to the width | variety of the said flat plate.
　上記の構成によると、進行方向に向かって対向するガイドローラーの最大径部分間の幅を平板の幅に合わせて進行方向に向かって徐々に狭くなるように配置できるので、同じ製造ラインで異なるサイズの平板を少しずつ確実に真っ直ぐに進むように修正することができる。そして、平板を進行方向に対して真っ直ぐに進むように押し戻すガイドローラーを、すべての回転軸にではなく、各ポジションの手前にのみ設けることで、ガイドローラーが平板に当接する回数が減り、しかも、異なるサイズの平板を送る前にガイドローラーの間隔のみを調整すればよいので、変更作業が容易である。 According to the above configuration, the width between the maximum diameter portions of the guide rollers facing in the traveling direction can be arranged so as to be gradually narrowed in the traveling direction according to the width of the flat plate. It can be modified to make sure that the flat plate of the plate advances straightly little by little. And by providing a guide roller that pushes back the flat plate so as to advance straight in the direction of travel, not only on all rotating shafts, but only in front of each position, the number of times the guide roller contacts the flat plate is reduced, Since it is only necessary to adjust the distance between the guide rollers before feeding the flat plates of different sizes, the changing operation is easy.
　第２の発明では、第１の発明において、
　上記ガイドローラーは、上記平板の幅を示す信号を受けて自動で位置変更可能に構成されている。 In the second invention, in the first invention,
The guide roller is configured to be able to change its position automatically in response to a signal indicating the width of the flat plate.
　上記の構成によると、画像処理やラベル認識等の手段により得られた平板の幅を示す信号に合わせて自動でガイドローラーの位置が変更されるので、異なるサイズの平板を流すときの設定が極めて容易であり、また、同じ製造ラインで、異なるサイズの平板であっても確実に直進性が確保される。 According to the above configuration, the position of the guide roller is automatically changed according to the signal indicating the width of the flat plate obtained by means such as image processing or label recognition, so the setting when flowing different size flat plates is extremely It is easy, and straightness is ensured with certainty even on flat plates of different sizes on the same production line.
　第３の発明では、第１又は第２の発明において、
　上記ガイドローラーは、進行方向に向かって徐々に狭くなった状態を保ったまま、連動して位置変更可能に構成されている。 In the third invention, in the first or second invention,
The guide roller is configured to be able to change the position in conjunction with the guide roller while maintaining a state of being gradually narrowed in the traveling direction.
　上記の構成によると、平板サイズに合わせて連動してガイドローラーの幅が変更されるので、異なるサイズの平板を流すときの変更作業がさらに容易となる。 According to the above configuration, since the width of the guide roller is changed in conjunction with the plate size, the change work when flowing different size plates is further facilitated.
　第４の発明では、第１乃至第３のいずれか１つの発明において、
　上記各ポジションの手前の上記複数の回転軸のうち、少なくとも手前側に設けた回転軸に設けた上記ガイドローラーにおける上記平板との当接面は、上記回転軸の軸方向内側に向かって外径が徐々に小さくなっている。 In a fourth invention, in any one of the first to third inventions,
Of the plurality of rotating shafts before each position, at least a contact surface of the guide roller provided on the rotating shaft provided on the near side with the flat plate has an outer diameter toward the inner side in the axial direction of the rotating shaft. Is gradually getting smaller.
　上記の構成によると、ガイドローラーの平板側面に対する当接面に傾斜が設けられているので、進行方向中心からずれたガラス基板の側面が滑らかにガイドローラーの当接面に当接し、さらに容易に平板の直進性が確保される。 According to the above configuration, since the contact surface with respect to the flat plate side surface of the guide roller is inclined, the side surface of the glass substrate that is shifted from the center of the traveling direction smoothly contacts the contact surface of the guide roller, further easily. Straightness of the flat plate is ensured.
　第５の発明では、第１乃至第４のいずれか１つの発明において、
　上記平板は、液晶表示パネルに使用するガラス基板とする。 In a fifth invention, in any one of the first to fourth inventions,
The flat plate is a glass substrate used for a liquid crystal display panel.
　上記の構成によると、大型化が進んでいる液晶表示パネル用のガラス基板を、傷を付けることなく、効率よく製造ライン上の各ポジションに搬送することができる。 According to the above configuration, a glass substrate for a liquid crystal display panel whose size is increasing can be efficiently transported to each position on the production line without being damaged.
　以上説明したように、本発明によれば、製造ラインの各ポジションの手前における複数の回転軸の軸方向外側に、互いの間隔が平板の進行方向に向かって徐々に狭くなるガイドローラーを平板の幅に合わせて位置変更可能に設けたことにより、同じ製造ラインで異なるサイズの平板をできるだけ平板の側面や表面に接触することなく、平板の直進性を保つように流すことができる。 As described above, according to the present invention, the guide roller whose distance between the rotating shafts gradually decreases toward the traveling direction of the flat plate on the outer side in the axial direction of the plurality of rotation shafts before each position of the production line. By providing the position changeable according to the width, it is possible to flow flat plates of different sizes on the same production line so as to keep the straightness of the flat plate as close as possible without contacting the side surface or the surface of the flat plate.

It plays the role of transporting the glass substrate G as a flat plate to each position above. As the size of the glass substrate G, for example, a size of about 3 m × about 3 m × 0.7 mm can be considered.
　図１及び図２に示すように、製造ラインＬ上のある２つのポジションに複数のガラス基板Ｇをカセット３に積み込むガラス第１及び第２基板振り分け装置５，６が配置されている。 As shown in FIGS. 1 and 2, glass first and second substrate sorting devices 5 and 6 for loading a plurality of glass substrates G into the cassette 3 are arranged at two positions on the production line L.
　そして、平板搬送装置１には、ガラス基板Ｇの進行方向に所定の間隔をあけて複数の搬送用回転軸７が配置されている。例えば、複数の搬送用回転軸７のうち、所定の箇所で搬送用回転軸７がモータ等で駆動され、その他の搬送用回転軸７は、特に動力を加えないで自由に回転するように構成されている。ガラス基板Ｇが搬送用ローラー８上で滑ってしまわないように、ガラス基板Ｇの搬送スピードは、例えば１０～３０ｍ／分に抑えられている。 In the flat plate transfer device 1, a plurality of transfer rotary shafts 7 are arranged at predetermined intervals in the traveling direction of the glass substrate G. For example, among the plurality of transport rotating shafts 7, the transport rotating shaft 7 is driven by a motor or the like at a predetermined location, and the other transport rotating shafts 7 are configured to freely rotate without applying power. Has been. In order to prevent the glass substrate G from sliding on the transport roller 8, the transport speed of the glass substrate G is suppressed to, for example, 10 to 30 m / min.
　各搬送用回転軸７には、複数の搬送用ローラー８が回転自在に配置されている。搬送用ローラー８の外径は、同一の搬送用回転軸７上では同一であるが、製造ラインＬ全体で一定というわけではなく、例えば、直径５０ｍｍ～３００ｍｍの任意の大きさである。搬送用ローラー８の間隔もガラス基板Ｇの大きさや厚さに合わせて変更すればよい。１本の搬送用回転軸７に配置される搬送用ローラー８は、同じ外径のものが略等間隔に配置され、その外周面がガラス基板Ｇの裏面側に当接してガラス基板Ｇを製造ラインＬの前方へ搬送するように構成されている。 A plurality of transport rollers 8 are rotatably arranged on each transport rotary shaft 7. The outer diameter of the transport roller 8 is the same on the same transport rotating shaft 7, but is not constant throughout the production line L, and is, for example, an arbitrary size with a diameter of 50 mm to 300 mm. What is necessary is just to change the space | interval of the roller 8 for conveyance according to the magnitude | size and thickness of the glass substrate G. FIG. Conveying rollers 8 arranged on one conveying rotating shaft 7 have the same outer diameter and are arranged at substantially equal intervals, and the outer peripheral surface thereof abuts on the back side of the glass substrate G to manufacture the glass substrate G. It is configured to convey the line L forward.
　そして、例えば、第１ガラス基板振り分け装置５と第２ガラス基板振り分け装置６との間の複数のアライメント用回転軸９，１０，１１において、軸方向中間には、上記搬送用回転軸７と同様に搬送用ローラー８が配置され、その軸方向外側に、この搬送用ローラー８よりも外径の大きいガイドローラー１３，１４，１５が設けられている。本実施形態では、例えば第１ガラス基板振り分け装置５と第２ガラス基板振り分け装置６との間に３本のアライメント用回転軸９，１０，１１が配置されている。そして、例えば、１番目のアライメント用回転軸９と２番目のアライメント用回転軸１０に設けたガイドローラー１３のガラス基板Ｇとの当接面は、アライメント用回転軸９，１０の軸方向内側に向かって外径が徐々に小さくなるテーパー面１３ａ，１４ａが形成されている。テーパー面１３ａ，１４ａの最小径は、搬送用ローラー８の外径と同等となっている。３番目のアライメント用回転軸１１のガイドローラー１４は、このようなテーパー面１３ａ，１４ａが設けられていない。 For example, in the plurality of alignment rotation shafts 9, 10, 11 between the first glass substrate distribution device 5 and the second glass substrate distribution device 6, in the middle in the axial direction, the same as the rotation shaft 7 for conveyance. The conveying roller 8 is arranged on the outer side, and guide rollers 13, 14, 15 having an outer diameter larger than that of the conveying roller 8 are provided on the outer side in the axial direction. In the present embodiment, for example, three alignment rotation shafts 9, 10, 11 are arranged between the first glass substrate distribution device 5 and the second glass substrate distribution device 6. For example, the contact surface of the guide roller 13 provided on the first alignment rotary shaft 9 and the second alignment rotary shaft 10 with the glass substrate G is on the inner side in the axial direction of the alignment rotary shafts 9 and 10. Tapered surfaces 13a and 14a are formed with gradually decreasing outer diameters. The minimum diameters of the tapered surfaces 13 a and 14 a are equal to the outer diameter of the transport roller 8. The guide roller 14 of the third alignment rotating shaft 11 is not provided with such tapered surfaces 13a, 14a.
　進行方向に向かって、１番目のアライメント用回転軸９から３番目のアライメント用回転軸１１に向かって対向するガイドローラー１３，１４，１５の最大径部分間の間隔は、徐々に狭くなっている。つまり、１番目のアライメント用回転軸９の対向するガイドローラー１３の最大径部分間の間隔Ｌ１、２番目のアライメント用回転軸１０の対向するガイドローラー１４の最大径部分間の間隔Ｌ２、３番目のアライメント用回転軸１１の対向するガイドローラー１５の軸方向内側間の間隔Ｌ３の順に徐々に小さくなっている（Ｌ１＞Ｌ２＞Ｌ３）。各ガイドローラー１３，１４，１５で順番に押し戻されたガラス基板Ｇの角部が製造ラインＬの前方（下流）のガイドローラー１４，１５に乗り上がってしまわないように、１番目の対向するガイドローラー１３の内側側面間の間隔と２番目の対向するガイドローラー１４の最大径部分間の間隔とがほぼ等しく、２番目のガイドローラー１４の内側側面の間隔と３番目の対向するガイドローラー１５の最大径部分間の間隔とがほぼ等しくなっている。そして、最も幅の狭い３番目のガイドローラー１５の間隔Ｌ３でも、少なくともガラス基板Ｇの幅Ｗよりも大きくなっている（Ｌ３＞Ｗ）。 The distance between the maximum diameter portions of the guide rollers 13, 14, 15 facing the direction from the first alignment rotary shaft 9 to the third alignment rotary shaft 11 gradually decreases in the traveling direction. . That is, the distance L2 between the maximum diameter portions of the opposing guide roller 13 of the first alignment rotating shaft 9, the interval L2 between the maximum diameter portions of the opposing guide roller 14 of the second alignment rotating shaft 10, and the third. Are gradually reduced in the order of the distance L3 between the axially inner sides of the guide rollers 15 facing the alignment rotating shaft 11 (L1> L2> L3). The first opposing guide so that the corners of the glass substrate G pushed back in turn by the guide rollers 13, 14, 15 do not get on the front (downstream) guide rollers 14, 15 of the production line L. The interval between the inner side surfaces of the roller 13 and the interval between the maximum diameter portions of the second opposing guide roller 14 are substantially equal, and the interval between the inner side surfaces of the second guide roller 14 and the third opposing guide roller 15 The distance between the largest diameter portions is almost equal. Even at the interval L3 of the third guide roller 15 having the narrowest width, at least the width W of the glass substrate G is larger (L3> W).
　そして、本発明の特徴として、対向する各ガイドローラー１３，１４，１５の間隔は、ガラス基板Ｇの幅に合わせて変更可能に構成されている。具体的には、各ガイドローラー１３，１４，１５のガラス基板Ｇの幅方向両外側には、幅変更機構２０がそれぞれ設けられており、この幅変更機構２０は、平板搬送装置１の制御部２１の信号を受けて伸縮するエアシリンダ２２を備えている。例えば、エアシリンダ２２のロッド２２ａには、操作用ブラケット２３が連結されている。操作用ブラケット２３の先端には、アライメント用回転軸９，１０，１１と同軸に３本の支持軸２３ａが回転自在に支持されている。各支持軸２３ａには、各ガイドローラー１３，１４，１５と回転一体に連結された連結パイプ２３ｂがそれぞれ回転一体に接続されている。連結パイプ２３ｂは、ガラス基板Ｇの進行方向に向かって徐々に長いものとなっている。このことで、エアシリンダ２２を伸縮させると、各ガイドローラー１３，１４，１５は、進行方向に向かって徐々に狭くなった状態を保ったまま、連動して位置変更可能に構成されている。 As a feature of the present invention, the interval between the opposing guide rollers 13, 14, 15 can be changed according to the width of the glass substrate G. Specifically, a width changing mechanism 20 is provided on each outer side in the width direction of the glass substrate G of each guide roller 13, 14, 15. The width changing mechanism 20 is a control unit of the flat plate transport device 1. An air cylinder 22 that expands and contracts in response to the signal 21 is provided. For example, the operation bracket 23 is connected to the rod 22 a of the air cylinder 22. Three support shafts 23 a are rotatably supported at the tip of the operation bracket 23 so as to be coaxial with the alignment rotation shafts 9, 10, and 11. Each support shaft 23a is connected to each guide roller 13, 14, 15 and a connecting pipe 23b that is connected to the support roller 23a so as to rotate together. The connecting pipe 23b is gradually longer in the traveling direction of the glass substrate G. Thus, when the air cylinder 22 is expanded and contracted, the guide rollers 13, 14, and 15 are configured to be able to change their positions in conjunction with each other while maintaining a gradually narrowed state in the traveling direction.
　　－作用－
　次に、本実施形態にかかる平板搬送装置１の作用について説明する。 -Action-
Next, the operation of the flat plate conveyance device 1 according to the present embodiment will be described.
　まず、定型にカットされて加工されたガラス基板Ｇを製造ラインＬ上に載せると、ガラス基板Ｇは、搬送用回転軸７上の搬送用ローラー８によって前方へ搬送される。製造ラインＬが長距離であると、搬送中にガラス基板Ｇが進行方向に対して左右にずれてくる場合がある。 First, when a glass substrate G that has been cut into a standard shape and processed is placed on the production line L, the glass substrate G is transported forward by the transport roller 8 on the transport rotating shaft 7. If the production line L is a long distance, the glass substrate G may be shifted left and right with respect to the traveling direction during conveyance.
　例えば、図１及び図２に示すように、第１ガラス基板振り分け装置５にて複数のガラス基板Ｇがカセット３に積み込まれ、残りのガラス基板Ｇは、さらに前方に搬送される。 For example, as shown in FIGS. 1 and 2, a plurality of glass substrates G are stacked in the cassette 3 by the first glass substrate sorting apparatus 5, and the remaining glass substrates G are further conveyed forward.
　第１ガラス基板振り分け装置５を通過したガラス基板Ｇが進行方向に対して左右いずれかの方向にずれていると、３本のアライメント用回転軸９，１０，１１の左右外側に設けたガイドローラー１３，１４，１５に当接する。 When the glass substrate G that has passed through the first glass substrate distribution device 5 is displaced in either the left or right direction with respect to the traveling direction, guide rollers provided on the left and right outer sides of the three alignment rotation shafts 9, 10, 11. 13, 14, 15 abuts.
　例えば、ガラス基板Ｇが左右に大きくずれていると、最初に一番手前のアライメント用回転軸９のガイドローラー１３に当接する。ガイドローラー１３のテーパー面１３ａは、徐々に左右内側に向かって外径が小さくなっているので、ガラス基板Ｇの左右側面が滑らかに当接し、左右内側へ押し戻しやすい。 For example, when the glass substrate G is largely displaced from side to side, the glass substrate G first comes into contact with the guide roller 13 of the front rotation shaft 9 for alignment. Since the taper surface 13a of the guide roller 13 gradually decreases in outer diameter toward the left and right inner sides, the left and right side surfaces of the glass substrate G come into contact smoothly and are easily pushed back to the left and right inner sides.
　１番目のガイドローラー１３で押し戻されたガラス基板Ｇは、１番目のガイドローラー１３よりも左右内側に配置された２番目のガイドローラー１４の当接面に当接してさらに左右内側へ押し戻される。このときも、ガイドローラー１４のテーパー面１４ａは、徐々に左右内側に向かって外径が小さくなっているので、ガラス基板Ｇの左右側面が滑らかに当接し、左右内側へ押し戻しやすい。 The glass substrate G pushed back by the first guide roller 13 comes into contact with the contact surface of the second guide roller 14 disposed on the left and right inner sides than the first guide roller 13 and is further pushed back to the left and right inside. Also at this time, since the outer diameter of the tapered surface 14a of the guide roller 14 gradually decreases toward the left and right inner sides, the left and right side surfaces of the glass substrate G abut smoothly and are easily pushed back to the left and right inner sides.
　次いで、ガラス基板Ｇは、２番目のガイドローラー１４よりも左右内側にあるガイドローラー１５で左右にぶれないように規制されながら、第２ガラス振り分け装置６に進入し、カセット３に積み込まれる。 Next, the glass substrate G enters the second glass sorting device 6 and is loaded on the cassette 3 while being regulated so as not to be moved left and right by the guide rollers 15 located on the left and right inner sides of the second guide roller 14.
　第２ガラス振り分け装置６で積み込まれなかったガラス基板Ｇは、さらに前方のポジションに搬送される。 The glass substrate G that has not been loaded by the second glass sorting device 6 is further transported to the front position.
　一方、ガラス基板Ｇの左右のブレが小さいときには、１番目のガイドローラー１３には当接せず、２番目のガイドローラー１４にまず当接し、同様にブレが修正される。 On the other hand, when the left and right blur of the glass substrate G is small, the glass substrate G is not brought into contact with the first guide roller 13, but is first brought into contact with the second guide roller 14, and the shake is corrected in the same manner.
　このように、ガイドローラー１３，１４，１５の幅が徐々に狭くなっているので、ガラス基板Ｇが確実に進行方向に真っ直ぐに進むように修正される。そして、ガラス基板Ｇを進行方向に対して真っ直ぐに押し戻すガイドローラー１３，１４，１５を、すべての回転軸７，９，１０，１１にではなく、各ポジションの手前にのみ設けることで、できるだけガイドローラー１３，１４，１５がガラス基板Ｇに当接する回数は最小限となる。 Thus, since the width of the guide rollers 13, 14, and 15 is gradually narrowed, the glass substrate G is corrected so as to surely advance straight in the traveling direction. The guide rollers 13, 14, 15 that push the glass substrate G straight back in the direction of travel are provided not only on all the rotating shafts 7, 9, 10, 11 but only in front of each position, thereby guiding as much as possible. The number of times the rollers 13, 14, and 15 contact the glass substrate G is minimized.
　このため、大型化が進んでいる液晶表示パネル用のガラス基板Ｇを、傷を付けることなく、効率よく製造ラインＬ上の各ポジションに搬送することができる。 For this reason, the glass substrate G for liquid crystal display panels whose size is increasing can be efficiently conveyed to each position on the production line L without being damaged.
　そして、同じ製造ラインＬ上に異なるサイズのガラス基板Ｇを流すときには、例えば、自動で、流れてきたガラス基板Ｇに付された信号発生部（図示せず）からガラス基板Ｇの幅を読み込んだり、画像処理によってガラス基板Ｇの幅を判断し、その幅を示す信号が制御部２１に送られる。その信号と、現在の各ガイドローラー１３，１４，１５間の距離とを比較して、必要な変位量を計算し、その分だけエアシリンダ２２を伸縮させる。すると、操作用ブラケット２３の連結パイプ２３ｂが移動して各ガイドローラー１３，１４，１５は、進行方向に向かって徐々に狭くなった状態を保ったまま連動する。 When flowing glass substrates G of different sizes on the same production line L, for example, the width of the glass substrate G is automatically read from a signal generation unit (not shown) attached to the flowing glass substrate G. The width of the glass substrate G is determined by image processing, and a signal indicating the width is sent to the control unit 21. The signal is compared with the current distance between the guide rollers 13, 14, and 15 to calculate a necessary displacement amount, and the air cylinder 22 is expanded or contracted by that amount. Then, the connecting pipe 23b of the operation bracket 23 moves, and the guide rollers 13, 14, and 15 are interlocked with each other while maintaining a gradually narrowed state in the traveling direction.
　このようにして、異なる幅を有するガラス基板Ｇを同じ製造ラインＬに流しても、自動で対向する各ガイドローラー１３，１４，１５の間隔を変更することにより、上記と同様にガラス基板Ｇを、傷を付けることなく、効率よく製造ラインＬ上の各ポジションに搬送することができる。 In this way, even when glass substrates G having different widths are flowed through the same production line L, the glass substrates G can be formed in the same manner as described above by automatically changing the interval between the guide rollers 13, 14, 15 facing each other. It can be efficiently transported to each position on the production line L without scratching.
　したがって、本実施形態にかかる平板搬送装置１によると、製造ラインＬの各ポジションの手前におけるアライメント用回転軸９，１０，１１の軸方向外側に、互いの間隔がガラス基板Ｇの進行方向に向かって徐々に狭くなるガイドローラー１３，１４，１５をガラス基板Ｇの幅に合わせて位置変更可能に設けたことにより、同じ製造ラインＬで異なるサイズのガラス基板Ｇでも、できるだけガラス基板Ｇの側面や表面に接触することなく、ガラス基板Ｇの直進性を保ちながら流すことができる。 Therefore, according to the flat plate transport device 1 according to the present embodiment, the distance between the rotation axes 9, 10, and 11 before the positions on the production line L is shifted outward in the axial direction of the glass substrate G. By providing guide rollers 13, 14, 15 that are gradually narrowed in accordance with the width of the glass substrate G, the position of the glass substrate G can be changed as much as possible. The glass substrate G can be made to flow while maintaining the straightness without contacting the surface.
　また、ガラス基板Ｇの幅を示す信号に合わせて自動でガイドローラー１３，１４，１５の位置が、進行方向に向かって徐々に狭くなった状態を保ったまま変更されるので、異なるサイズのガラス基板Ｇを流すときの設定を極めて容易に行うことができる。 In addition, since the positions of the guide rollers 13, 14, and 15 are automatically changed in accordance with a signal indicating the width of the glass substrate G while being gradually narrowed in the traveling direction, glass of different sizes is used. Setting for flowing the substrate G can be performed very easily.
