Description

【0001】
【発明の属する技術分野】
本発明は板状体の搬送装置に関する。
【0002】
【従来の技術】
ガラス基板、ガラス基板を用いた液晶パネル、太陽電池パネル等の薄板状体の搬送には、従来からベルトコンベヤ、ローラコンベヤ、ホイールコンベヤ等の搬送装置が使用されており、ホイールコンベヤを用いたガラス基板等の薄板状体の搬送装置の従来の一例は図9〜図13に示されている。而して、搬送装置は、図12に示すように、平面的に見て薄板状体搬送方向Dに対し直交する方向へ一定の間隔で配置された複数列のホイールコンベヤaを、薄板状体搬送方向Dに対し平行な方向へ複数組備えている。
【0003】
各ホイールコンベヤaは、図9〜図11に示すように、枠体bと、該枠体bに薄板状体搬送方向Dと平行な方向へ一定間隔で配置された比較的幅狭の複数の水平配置されたホイールcを備え、ホイールcは図示してないが、従来周知の駆動手段により同一周速度で駆動し得るようになっている。
【0004】
而して、図12に示すごとく、薄板状体搬送方向Dに対し上流側における複数列のホイールコンベヤaの薄板状体搬送方向D下流端におけるホイールcと、薄板状体搬送方向Dに対し下流側の複数列のホイールコンベヤaの薄板状体搬送方向D上流端のホイールcとは、互に軸線方向に隣合うよう、同一軸線上に配置されているが、これは、薄板状体eが搬送時に上流側のホイールコンベヤaから下流側のホイールコンベヤaへ円滑に乗り移れるようにするためである。
【0005】
薄板状体eを搬送する場合には、ホイールコンベヤaのホイールcは全て駆動されて回転している。このため、上流側のホイールコンベヤaに移送された薄板状体eは、上流側のホイールコンベヤaを搬送されて下流側のホイールコンベヤaに移送され、下流側のホイールコンベヤaにより更に搬送される。
【0006】
薄板状体を搬送する他の搬送装置の例としては、特許文献1に示すごとき搬送装置がある。該搬送装置では、薄板状体の搬送方向に沿う両端付近を支持すると共に、薄板状体を下流方向へ搬送する水平ローラを備えている。
【0007】
【特許文献1】
特開平9−278181号公報
【0008】
【発明が解決しようとする課題】
しかしながら、図9〜図13に示す搬送装置の場合、薄板状体eの先端部は、薄板状体搬送方向Dへ移動してホイールcに支持されない片持ちの状態になった際に、自重により下方へ撓み、このため、薄板状体eの先端は薄板状体搬送方向D下流側の次のホイールcに乗り移る際に、ホイールcの外周面に当接して振動し、その結果、薄板状体eに悪影響を与える虞がある。
【0009】
又、薄板状体eの先端が下流側のホイールcに乗り移る際に、当該ホイールcに当接すると、薄板状体eは下流側のホイールcから力を受け、その結果、薄板状体eは位置がずれて蛇行する虞があり、従って従来の搬送装置では、蛇行防止のためサイドガイドが必要になる。
【0010】
更に、ホイールcの外周面に塵埃が付着すると、薄板状体eにも塵埃が付着する虞がある。
【0011】
特許文献1に示す搬送装置の場合には、左右のローラの間に給気プレートの上方に位置するよう多孔質部材を配置し、多孔質部材から薄板状体の下面に空気を供給して薄板状体の下面に塵埃が付着しないようにしている。しかし、薄板状体の先端が下流側のローラに乗り移る際には、図9〜図13に示す搬送装置と同様、ローラの外周面に当接する。このため、薄板状体が振動による悪影響を受けたり、蛇行する虞があることや、蛇行防止にはサイドガイドが必要となることは、図9〜図13の搬送装置の場合と同様である。
【0012】
本発明は、斯かる実情に鑑み、薄板状体の搬送時の振動を軽減すると共に、蛇行を防止し、しかも、薄板状体に塵埃が付着する虞のない板状体の搬送装置を提供することを目的としてなしたものである。
【0013】
【課題を解決するための手段】
請求項1の板状体の搬送装置は、板状体搬送方向に間隔を置いて配置された回転体に駆動可能に巻き掛けられた無端状の帯状体又は紐状体と、該帯状体又は紐状体の板状体搬送方向と平行な方向へ間隔を置いて取り付けられ且つ搬送側で板状体を支持し得るようにした支持体と、を備えたものである。
【0014】
請求項2の板状体の搬送装置は、前記帯状体又は紐状体を平面視で板状体搬送方向に対し直交する方向へ複数列配置したものである。
【0015】
請求項3の板状体の搬送装置は、前記帯状体又は紐状体を平面視で板状体搬送方向に対し平行な方向へ複数組配置したものである。
【0016】
請求項4の板状体の搬送装置は、上流側の帯状体又は紐状体の板状体搬送方向下流側の部分と、下流側の帯状体又は紐状体の板状体搬送方向上流側の部分とを、側面視で重なるよう配置したものである。
【0017】
請求項5の板状体の搬送装置は、前記回転体及び帯状体又は紐状体を、該帯状体又は紐状体に取り付けた支持体の搬送側における頂部が上方へ突出するよう、被覆体で覆ったものである。
【0018】
請求項6の板状体の搬送装置は、前記被覆体内の排気を行う排気手段を設けたものである。
【0019】
本発明の板状体の搬送装置によれば、搬送時における板状体の振動を軽減することができると共に、蛇行を防止することができるため、搬送により板状体に悪影響が及ぶことがなく、且つ品質を良好に保持でき、しかもサイドガイドが不要であるため、設備費を低減することができ、又、排気手段により枠体内を排気するようにしているため、帯状体や紐状体に取り付けた板状体の支持体に塵埃が付着することを低減でき、その結果、板状体に塵埃が付着する虞が低減してその品質を損なう虞が軽減される。
【0020】
【発明の実施の形態】
以下、本発明の実施の形態を添付図面を参照して説明する。
図1〜図8は本発明を実施する形態の一例である。
図1〜図4において、1は搬送装置本体であり、搬送装置本体1は、薄板状体搬送方向Dと平行な方向へ延在する枠体2を備えている。枠体2は、底面及び両側面並びに前後面を板状の被覆体で覆われた直方体状に形成され、上面には長手方向に対し略全長に亘り開口2aが形成されている。
【0021】
枠体2内の薄板状体搬送方向D上流端及び下流端近傍には、プーリ3,4が水平設置されており、プーリ3,4には無端状で且つ狭幅のベルト5が掛け渡されている。ベルト5の表面には、搬送側において頂部側が開口2aから上方へ僅かに突出して搬送される薄板状体6の下面を支持し得るようにした突起状支持体7が取り付けられている。突起状支持体7は例えば樹脂製で、その頂部は図5に示すように、半円形に形成されている。このようにするのは、薄板状体6の被支持部分に傷が付いたり塵埃が付着するのを防止するためである。
【0022】
プーリ3,4が外嵌、固定された軸8,9は、例えば、枠体2の外側部に設けた軸受に回転自在に支持され、軸8又は9は、従来周知の駆動装置によって回転駆動されるようになっている。而して、軸8又は9を駆動することにより、プーリ3,4を介してベルト5が回動し、ベルト5の回動により突起状支持体7が移動し得るようになっている。図1中、10は枠体2内の空気を排気するための排風機等の排気手段である。
【0023】
上記搬送装置本体1は、図6に示すように、平面視で、薄板状体搬送方向Dに対し直交する方向へ所定の間隔で複数列配置さており、複数列の搬送装置本体1は薄板状体搬送方向Dに対し複数組配置されており、全ての搬送装置本体1の突起状支持体7の上端は同一平面上に位置している。
【0024】
而して、薄板状体搬送方向Dに対し上流側の搬送装置本体1の下流側端部と下流側の搬送装置本体1の上流側端部とは、図6に示すように、互に幅方向に隣合って入れ子状に配置され、上流側の搬送装置本体1における先端のプーリ3と下流側の搬送装置本体1における後端のプーリ4の軸線は同一線上に位置するようになっている。而して、側面視で、上流側の搬送装置本体1における先端のプーリ3と下流側の搬送装置本体1における後端のプーリ4、ベルト5の一部は重なるようになっている。
【0025】
このようにするのは、上流側の先端部の突起状支持体7と下流側の後端部の突起状支持体7との間の間隔が大きくならないようにし、薄板状体6が上流側の搬送装置本体1から下流側の搬送装置本体1に乗り移る際に、ベルト5の回動により下降する上流側先端の突起状支持体7が、薄板状体6の先端部下面から外れても、薄板状体6先端部の自重による撓みが大きくならないようにし、下流側後端部のベルト5の回動により上昇してくる突起状支持体7に円滑に支持されるようにするためである。
【0026】
次に、上記した実施の形態の作動を説明する。
薄板状体6を搬送する際には、全ての搬送装置本体1は駆動されており、従って、搬送側において、突起状支持体7はベルト5と共に薄板状体搬送方向Dへ移動しており、又、全ての枠体2内は、排気手段10により排気されている。
【0027】
上流側の複数列の搬送装置本体1に移送された薄板状体6は、上流側の搬送装置本体1の突起状支持体7に支持されて突起状支持体7と共に薄板状体搬送方向D下流側へ搬送され、上流側の複数列の搬送装置本体1から下流側の複数列の搬送装置本体1に乗り移り、下流側の複数列の搬送装置本体1の突起状支持体7に支持されて突起状支持体7と共に薄板状体搬送方向D下流側へ搬送される。
【0028】
又、上流側の複数列の搬送装置本体1により搬送された薄板状体6が下流側の複数列の搬送装置本体1に乗り移る際には、上流側の搬送装置本体1における突起状支持体7は、先端部におけるプーリ3の回転に伴うベルト5の下方への回動により下降して薄板状体6の下面から離反するが、略同時に下流側の搬送装置本体1における突起状支持体7が、後端部におけるプーリ4の回転に伴うベルト5の上方への回動により上昇して薄板状体6の下面を支持する。
【0029】
従って、搬送時には、薄板状体6は突起状支持体7に支持されて突起状支持体7と共に薄板状体搬送方向Dへ移動し、薄板状体6は突起状支持体7に対し位置がずれることがない。その結果、薄板状体6の搬送時の振動が軽減されると共に、薄板状体6には蛇行が生じない。そのため、搬送により薄板状体6が悪影響を受けることがなく、品質を良好に保持できると共に、サイドガイドが不要であるため、設備費を低減することができる。
【0030】
又、排気手段10による枠体2内の排気により、ベルト5や突起状支持体7に塵埃が付着する虞が低減されるため、薄板状体6に塵埃が付着して品質を損なう虞が軽減される。
【0031】
なお、本発明の板状体の搬送装置においては、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることができる。すなわち、平面視で薄板状体搬送方向に対し直交する方向へ複数列に配置した搬送装置本体を、薄板状体搬送方向に複数組配置する場合について説明したが、複数の突起状支持体が取り付けられたベルトを平面視で薄板状体搬送方向に対し直交する方向に複数列配置すれば、前記ベルトを薄板状体搬送方向に対し複数組配置しなくても実施可能である。
【0032】
又、帯状体であるベルトに突起状支持体を取り付ける場合について説明したが、突起状支持体をチェーン、ロープ等の紐状体に取り付けるようにしても実施でき、搬送される板状体は薄板に限らず種々の厚さのものに適用することができ、排気手段は各搬送装置本体の枠体に夫々設けても、或は、排気手段は1基とし、該排気手段をダクトにより各枠体と接続するようにしても実施することができる。
【0033】
更に、プーリ及びベルト並びに突起状支持体の薄板状体搬送側における頂部近傍以外の部分を覆う被覆体は、個々の搬送装置本体ごとに設置する場合について説明したが、全体を1組の被覆体で覆うようにしても実施することができる。
【0034】
【発明の効果】
以上、説明したように本発明の請求項1〜6に記載の板状体の搬送装置によれば、搬送時における板状体の振動を軽減することができると共に、蛇行を防止することができるため、搬送により板状体に悪影響が及ぶことがなく、且つ品質を良好に保持でき、しかもサイドガイドが不要であるため、設備費を低減することができ、又、排気手段により枠体内を排気するようにしているため、帯状体や紐状体に取り付けた板状体の支持体に塵埃が付着することを低減でき、その結果、板状体に塵埃が付着する虞が低減してその品質を損なう虞が軽減される、等種々の優れた効果を奏し得る。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a plate-like body conveying device.
[0002]
[Prior art]
Conventionally, conveyors such as belt conveyors, roller conveyors, and wheel conveyors have been used to convey thin substrates such as glass substrates, liquid crystal panels and solar cell panels using glass substrates, and glass using wheel conveyors. FIGS. 9 to 13 show an example of a conventional device for transporting a thin plate such as a substrate. Thus, as shown in FIG. 12, the transport device includes a plurality of rows of wheel conveyors a that are arranged at regular intervals in a direction orthogonal to the thin plate transport direction D when viewed in a plan view. A plurality of sets are provided in a direction parallel to the transport direction D.
[0003]
As shown in FIGS. 9 to 11, each wheel conveyor a includes a frame b, and a plurality of relatively narrow widths arranged at regular intervals on the frame b in a direction parallel to the sheet-like body conveying direction D. A horizontally arranged wheel c is provided. Although not shown, the wheel c can be driven at the same peripheral speed by a conventionally known driving means.
[0004]
Thus, as shown in FIG. 12, a plurality of rows of wheel conveyors a on the upstream side with respect to the laminar body transport direction D have a wheel c at the downstream end in the lamellar body transport direction D and a downstream end with respect to the lamellar body transport direction D. The plurality of rows of wheel conveyors a are arranged on the same axis so as to be adjacent to each other in the axial direction with the wheel c at the upstream end in the laminar body transport direction D. This is to enable smooth transfer from the wheel conveyor a on the upstream side to the wheel conveyor a on the downstream side during transport.
[0005]
When transporting the thin plate member e, all the wheels c of the wheel conveyor a are driven and rotated. For this reason, the thin plate-shaped body e transferred to the upstream wheel conveyor a is transferred to the downstream wheel conveyor a by being transferred to the upstream wheel conveyor a, and further transferred by the downstream wheel conveyor a. .
[0006]
As an example of another transporting device for transporting a thin plate, there is a transporting device as disclosed in Japanese Patent Application Laid-Open Publication No. H11-163873. The transfer device includes horizontal rollers that support the vicinity of both ends of the thin plate in the transfer direction and transfer the thin plate in the downstream direction.
[0007]
[Patent Document 1]
JP-A-9-278181
[Problems to be solved by the invention]
However, in the case of the transfer device shown in FIGS. 9 to 13, when the tip end of the thin plate-like body e moves in the thin plate-like body transfer direction D to be in a cantilever state that is not supported by the wheel c, due to its own weight. When the tip of the thin plate e moves to the next wheel c on the downstream side in the thin plate transport direction D, the tip of the thin plate e vibrates by contacting the outer peripheral surface of the wheel c. e may be adversely affected.
[0009]
Further, when the tip of the thin plate-shaped member e comes into contact with the downstream wheel c when moving to the downstream wheel c, the thin plate-shaped member e receives a force from the downstream wheel c, and as a result, the thin plate-shaped member e There is a risk that the position will shift and meander. Therefore, in the conventional transport device, a side guide is required to prevent meandering.
[0010]
Further, when dust adheres to the outer peripheral surface of the wheel c, there is a possibility that the dust adheres to the thin plate-like body e.
[0011]
In the case of the transfer device described in Patent Document 1, a porous member is disposed between the left and right rollers so as to be located above an air supply plate, and air is supplied from the porous member to the lower surface of the thin plate-shaped member to supply the thin plate. Dust does not adhere to the lower surface of the body. However, when the leading end of the thin plate-like body moves onto the roller on the downstream side, it comes into contact with the outer peripheral surface of the roller, similarly to the transfer device shown in FIGS. For this reason, as in the case of the transfer apparatus shown in FIGS. 9 to 13, the thin plate member may be adversely affected by vibration or may meander, and a side guide may be required to prevent meandering.
[0012]
The present invention has been made in view of the above circumstances, and provides a plate-like body transfer apparatus that reduces vibration during the transfer of a sheet-like body, prevents meandering, and has no risk of dust adhering to the sheet-like body. It was done for the purpose.
[0013]

[0014]
According to a second aspect of the present invention, the belt-shaped body or the string-shaped body is arranged in a plurality of rows in a direction orthogonal to the plate-shaped body transport direction in a plan view.
[0015]
According to a third aspect of the present invention, there is provided the plate-like body transfer device, wherein a plurality of sets of the band-like body or the string-like body are arranged in a direction parallel to the plate-like body transfer direction in a plan view.
