特開2002−321820号公報JP 2002-321820 A

上記特許文献1における搬送装置では、推進力付与手段が、搬送物における搬送方向と直交する横幅方向の両端側に対して推進力を付与する両側駆動式に構成されており、搬送方向と直交する横幅方向の一端側と他端側との両側に対して推力を付与する構成であり、推進力付与手段に、搬送物の横幅方向での一端側に推進力を付与する機構と一端側の横幅方向での反対側の他端側に推進力を付与する機構との一対の機構を備える必要があったり、その一対の機構の一方から他方に動力を伝達する機構が必要であったりして、推進力付与手段の構成が複雑なものとなり、推進力付与手段の重量が重いものとなっていた。   In the transport apparatus in Patent Document 1, the propulsive force applying means is configured as a double-sided drive type that applies a propulsive force to both ends in the width direction orthogonal to the transport direction of the transported object, and is orthogonal to the transport direction. A structure that applies thrust to both sides of one end side and the other end side in the lateral width direction, and a mechanism that applies propulsive force to one end side in the lateral width direction of the conveyed product and the lateral width on one end side. It is necessary to provide a pair of mechanisms with a mechanism for applying a propulsive force to the other end side opposite to the direction, or a mechanism for transmitting power from one of the pair of mechanisms to the other, The configuration of the propulsion force applying means is complicated, and the weight of the propulsion force applying means is heavy.

本発明の目的は、推進力付与手段の構成を簡素なものとして推進力付与手段の重量を軽くすることのできる搬送装置を提供する点にある。   An object of the present invention is to provide a transport device capable of reducing the weight of the propulsive force applying means by simplifying the configuration of the propulsive force applying means.

本願発明に係る搬送装置の第1特徴構成は、ガラス基板の下面に向けて清浄空気を供給して、前記ガラス基板を非接触状態に支持する送風式支持手段と、その送風式支持手段にて支持される前記ガラス基板に対して搬送方向での推進力を付与する推進力付与手段とが備えられている搬送装置であって、
前記送風式支持手段が、前記ガラス基板を搬送方向視にて傾けた姿勢で支持するように構成され、
前記推進力付与手段が、前記ガラス基板における前記搬送方向と直交する横幅方向の傾斜下方側となる一端側に対して推進力を付与する片側駆動式に構成され、且つ、前記ガラス基板の下面を接触支持して推進力を付与する接触式の駆動部を備えて構成され、
前記駆動部が、前記ガラス基板における推進力が付与される一端側の側面に接当して、前記横幅方向に移動する前記ガラス基板を受け止める受け止め部を備えて構成され、
前記送風式支持手段が、搬送経路を搬送される前記ガラス基板の下方に、そのガラス基板の下面に沿う姿勢で配置されて塵埃を除去する除塵フィルタと、その除塵フィルタを通して前記ガラス基板の下面に向けて清浄空気を供給する電動式の複数の送風ファンとを、前記複数の送風ファンが並ぶ状態でかつ前記除塵フィルタが前記複数の送風ファンの上方を覆う状態で備え、前記ガラス基板の下面に供給される清浄空気の量搬送方向においても横幅方向においても同量とするべく、前記複数の送風ファンが同等の回転速度で駆動するように構成され、且つ、前記ガラス基板を前記推進力付与手段にて推進力が付与される一端側よりも前記横幅方向の他端側が上方に位置するように傾けた姿勢で支持するように、前記推進力付与手段にて推進力が付与される前記ガラス基板の一端側に対応する側ほど下方に位置する傾斜姿勢で設けられている点を特徴とする。
The first characteristic configuration of the transport device according to the present invention is the blow-type support means for supplying clean air toward the lower surface of the glass substrate and supporting the glass substrate in a non-contact state, and the blow-type support means. A transport device provided with a propulsive force applying means for applying a propulsive force in the transport direction to the glass substrate to be supported;
The blower-type support means is configured to support the glass substrate in a tilted position as viewed in the conveyance direction,
The propulsive force applying means is configured to be a one-side drive type that applies a propulsive force to one end side that is an inclined lower side in the lateral width direction orthogonal to the transport direction in the glass substrate, and the lower surface of the glass substrate is Consists of a contact-type drive unit that supports and applies propulsive force,
The drive unit is configured to include a receiving portion that receives the glass substrate that moves in the lateral width direction in contact with a side surface on one end side to which a driving force is applied in the glass substrate,
The blower-type support means is disposed below the glass substrate that is transported along the transport path in a posture along the lower surface of the glass substrate, and removes dust, and through the dust filter to the lower surface of the glass substrate. A plurality of electric blower fans for supplying clean air toward the glass substrate in a state where the plurality of blower fans are lined up and in a state where the dust filter covers the top of the plurality of blower fans , The plurality of blower fans are configured to be driven at the same rotational speed so that the amount of clean air supplied is the same in both the conveying direction and the lateral width direction, and the glass substrate is provided with the propulsive force. Propulsion by the propulsive force applying means so that the other end side in the lateral width direction is positioned so as to be located above the one end side to which the propulsive force is applied by the means. There characterized that provided in an inclined position which is located downward and the side corresponding to one side of the glass substrate applied.

すなわち、推進力付与手段が、送風式支持手段にて非接触状態で支持されているガラス基板に対して、ガラス基板における搬送方向と直交する横幅方向の一端側に対して推進力を付与する片側駆動式に構成されているので、推進力付与手段としては、ガラス基板における横幅方向における一端側に対して推進力を付与する構成でよく、前記一端側の横幅方向での反対側の他端側に推進力を付与する必要がない。従って、前記一端側の横幅方向での反対側の他端側に推進力を付与する機構を備える必要がなかったり、その機構に対して動力を伝達する必要がなかったりするので、推進力付与手段の構成を簡素なものとして推進力付与手段の重量を軽くすることのできる搬送装置を提供できるに至った。
また、送風式支持手段は、ガラス基板を前記推進力付与手段にて推進力が付与される一端側よりも横幅方向の他端側が上方に位置するように傾けた姿勢で支持するため、ガラス基板は、ガラス基板の自重によって斜め下方に推進力が付与されてガラス基板の傾きに沿って移動しようとするが、そのガラス基板の斜め下方への移動を、受け止め部がガラス基板の側面に接当することにより受け止めることができる。
従って、ガラス基板の横幅方向での一方側への移動を受け止め部にて規制することができ、ガラス基板の横幅方向の他端側への移動をガラス基板の自重によって移動しにくくすることができるので、ガラス基板を搬送する際にガラス基板が横幅方向にずれてしまったり、傾いたりする可能性が少なくなり、ガラス基板を円滑に搬送することができる。
また、推進力付与手段における接触式の駆動部にて、ガラス基板の下面を支持しながら推進力を付与するものであるため、送風式支持手段との協同によってガラス基板を支持することによってガラス基板をより安定した状態で支持することができ、また、ガラス基板の厚さ方向の自重によりガラス基板の下面が駆動部に押し付けられるので摩擦力が高まり、ガラス基板に対する推進力の付与も確実に行うことができて、ガラス基板を円滑に搬送することができる。
また、受け止め部は駆動部に備えられているので、受け止め部を別途設ける必要がなくなり、それほど搬送装置の構成を複雑化させずに受け止め部を備えることができ、また、ガラス基板の厚さ方向の自重によりガラス基板の下面が駆動部に押し付けられ、ガラス基板の横幅方向の自重によりガラス基板の側面が駆動部に押し付けられるので摩擦力がさらに高まり、ガラス基板に対する推進力の付与もより確実に行うことができて、ガラス基板を円滑に搬送することができる。
That is, one side propulsion force applying means, that the glass substrate is supported in a non-contact state by blowing type support means for imparting a propulsion force to one end of the horizontal width direction orthogonal to the conveying direction of the glass substrate Since it is configured to be driven, the propulsive force applying means may be configured to apply a propulsive force to one end side in the width direction of the glass substrate , and the other end side on the opposite side in the width direction of the one end side There is no need to give propulsion to Therefore, it Tsu Naka necessary to provide a mechanism for imparting a propulsion force to the opposite side the other end of the lateral width direction of the one end side, so or did not need to transmit power for the mechanism, propulsion force imparting It has become possible to provide a transport device that can reduce the weight of the propulsion force applying means by simplifying the structure of the means.
Further, the blower support means supports the glass substrate in an inclined posture so that the other end side in the lateral width direction is located above the one end side to which the propulsive force is applied by the propulsive force applying means. In this case, a propulsive force is applied obliquely downward due to the weight of the glass substrate and attempts to move along the inclination of the glass substrate, but the receiving portion contacts the side surface of the glass substrate. You can catch it.
Therefore, the movement to the one side in the horizontal width direction of the glass substrate can be restricted by the catching portion, and the movement of the glass substrate to the other side in the horizontal width direction can be made difficult to move by the weight of the glass substrate. Therefore, the possibility that the glass substrate is displaced in the lateral width direction or tilted when the glass substrate is conveyed is reduced, and the glass substrate can be smoothly conveyed.
In addition, since the contact-type drive unit in the propulsive force applying means applies the propulsive force while supporting the lower surface of the glass substrate, the glass substrate is supported by supporting the glass substrate in cooperation with the blower-type support means. Can be supported in a more stable state, and the lower surface of the glass substrate is pressed against the driving portion by its own weight in the thickness direction of the glass substrate, so that the frictional force is increased and the propulsive force is reliably applied to the glass substrate. And the glass substrate can be transported smoothly.
In addition, since the receiving portion is provided in the driving portion, it is not necessary to provide the receiving portion separately, and the receiving portion can be provided without complicating the configuration of the transport device so much, and the thickness direction of the glass substrate The lower surface of the glass substrate is pressed against the driving unit by its own weight, and the side surface of the glass substrate is pressed against the driving unit by its own weight in the width direction of the glass substrate. The glass substrate can be smoothly transported.

特徴構成は、上記第1特徴構成に加えて、前記送風式支持手段が、前記除塵フィルタと前記送風ファンとを一体的に組み付けた送風ユニットを、前記搬送方向に並べて構成されている点を特徴とする。 The second characteristic feature, in addition to the first feature structure, the blower type support means, a blower unit assembled integrally with said blower fan and the dust filter is configured by arranging in the transport direction Features a point.

従って、送風ファンと除塵フィルタとを一体的に組み付けた送風ユニットをガラス基板の搬送方向に並べて備えるだけで、搬送されるガラス基板の下面に向けて清浄空気を供給してガラス基板を非接触状態で支持する送風式支持手段を設置することができるので、送風式支持手段の設置が簡単なものとなり、もって、製作の容易化を図ることができる搬送装置を提供することができる。 Thus, the blower fan and dust filter and blower unit assembled integrally with the only provided side by side in the conveying direction of the glass substrate, a non-contact state of the glass substrate by supplying clean air toward the bottom surface of the glass substrate to be transported Therefore, it is possible to provide a conveying apparatus that can be easily manufactured.

そして、上記したように、前記搬送ユニット1を、搬送方向視で収納フレーム8を備えている側ほど下方に位置するような傾斜状態で支持することにより、その搬送ユニット1における送風式支持手段3は、搬送方向視にて、ガラス基板2の推進一端側2bに対応する側ほど下方に位置させるように設けられている。よって、図2〜図4に示すように、送風式支持手段3に横幅方向に沿って設けられる整風板15も、搬送方向視にて、ガラス基板2の推進一端側2bに対応する側ほど下方に位置させるように設けられている。   And as above-mentioned, by supporting the said conveyance unit 1 in the inclined state which is located below so that the side provided with the storage frame 8 by the conveyance direction view, the ventilation type support means 3 in the conveyance unit 1 Is provided so that the side corresponding to the propulsion one end 2b of the glass substrate 2 is positioned lower in the conveyance direction view. Therefore, as shown in FIGS. 2 to 4, the air conditioning plate 15 provided along the lateral width direction on the blower-type support means 3 is also lower as the side corresponding to the propulsion one end side 2 b of the glass substrate 2 in the transport direction view. It is provided so that it may be located in.

次に、前記推進力付与手段4について説明する。図2に示すように、前記ガラス基板2に対して搬送方向での推進力を付与する推進力付与手段4は、ガラス基板2の推進一端側2bに対して推進力を付与する片側駆動式に構成されており、推進力付与手段4には、ガラス基板2の下面2aを接触支持して推進力を付与する接触式の駆動部としての駆動ローラ24が備えられている。そして、この駆動ローラ24には、図4、図9に示すように、ガラス基板2の推進一端側2bの側面に接当して、横幅方向に移動するガラス基板2を受け止める受け止め部としての大径部24aが備えられている。   Next, the propulsion force applying means 4 will be described. As shown in FIG. 2, the driving force applying means 4 for applying a driving force in the transport direction to the glass substrate 2 is a one-side drive type that applies a driving force to the driving one end 2 b of the glass substrate 2. The driving force applying means 4 is provided with a driving roller 24 as a contact type driving unit that supports and supports the lower surface 2a of the glass substrate 2 to apply a driving force. As shown in FIGS. 4 and 9, the driving roller 24 is in contact with the side surface of the propulsion end side 2b of the glass substrate 2, and serves as a large receiving portion for receiving the glass substrate 2 moving in the lateral width direction. A diameter portion 24a is provided.

推進力付与機構4について詳述すると、図4、図8、図9、図10に示すように、電動モータ25と、この電動モータ25の出力ギヤと噛み合う平歯車28を備えた伝動軸27と、伝動軸27に備えられた出力ギヤ29と噛み合う入力ギヤ30を備えた多数の出力軸26とを備えて構成されている。そして、伝動モータ25及び伝動軸27は前記搬送空間B内に配備されており、前記出力軸26は、収納空間B側並びに搬送空間A側にそれぞれ突出する状態で前記内壁8aに回転自在に支持されている。出力軸26の収納空間Bに突出する部分には前記入力ギヤ30が備えられており、出力軸26の搬送空間Aに突出する部分には前記駆動ローラ24が備えられている。   The propulsion force imparting mechanism 4 will be described in detail. As shown in FIGS. 4, 8, 9, and 10, an electric motor 25 and a transmission shaft 27 that includes a spur gear 28 that meshes with an output gear of the electric motor 25. , And a plurality of output shafts 26 each having an input gear 30 that meshes with an output gear 29 provided on the transmission shaft 27. The transmission motor 25 and the transmission shaft 27 are disposed in the transport space B, and the output shaft 26 is rotatably supported on the inner wall 8a in a state of projecting to the storage space B side and the transport space A side. Has been. The input gear 30 is provided in a portion of the output shaft 26 protruding into the storage space B, and the drive roller 24 is provided in a portion of the output shaft 26 protruding into the transport space A.

従って、送風式支持手段3にて、送風ファン13の送風作用により、送風ファン13の下方から吸引した空気を、除塵フィルタ12を通り、整風板16の通気孔16aを通って清浄空気としてガラス基板2の下面2aに供給し、その供給した清浄空気にてガラス基板2の下面2aの略全域が支持されている。また、推進力付与手段4にて、ガラス基板2の推進一端側2bの下面が駆動ローラ24にて接触支持されている。そして、そのガラス基板2を接触支持している駆動ローラ24が電動モータ25にて駆動回転されることによって、推進一端側2bに対して搬送方向への推進力が付与されてガラス基板2が搬送される。   Accordingly, the air that is sucked from the lower side of the blower fan 13 by the blower fan 13 by the blower support means 3 passes through the dust filter 12 and passes through the ventilation holes 16a of the air conditioning plate 16 as clean air. 2 is supplied to the lower surface 2a of the glass substrate 2, and substantially the entire area of the lower surface 2a of the glass substrate 2 is supported by the supplied clean air. Further, the lower surface of the propulsion one end 2 b of the glass substrate 2 is contacted and supported by the driving roller 24 by the propulsive force applying means 4. The driving roller 24 that contacts and supports the glass substrate 2 is driven and rotated by the electric motor 25, whereby a propulsive force in the conveying direction is applied to the propulsion one end side 2b, and the glass substrate 2 is conveyed. Is done.

そして、搬送方向においても横幅方向においても整風板15から略同量の清浄空気がガラス基板2の下面2aに供給されて、ガラス基板2は整風板15に対して略一定の間隔をもって支持されることとなる。よって、整風板15がガラス基板2の推進一端側2bに対応する側ほど下方に位置させるように設けられているので、ガラス基板2も推進一端側2bよりも他端側2cが上方に位置するように傾けた姿勢で支持されている。尚、この傾けた姿勢のガラス基板2は、0.5°程度のわずかな傾きであり、略水平姿勢に含まれる。
従って、ガラス基板2は傾けた姿勢で支持することにより、ガラス基板2の自重により横幅方向における傾斜下方側となる推進力付与手段4を備えた側に移動しようとするが、そのガラス基板2の移動は駆動ローラ24の大径部24aにて受け止められる。よって、ガラス基板2の横幅方向の一方側への移動は駆動ローラ24の大径部24aにて規制され、ガラス基板2の横幅方向の他端側へはガラス基板2の自重によって移動しにくくなるので、搬送終了時にガラス基板を制動させる際等に、ガラス基板が横幅方向にずれてしまったり搬送方向に対して姿勢が斜めになってしまったりすることを防ぐことができる。また、ガラス基板2の自重によってガラス基板2が駆動ローラ24に押し付けられるので、駆動ローラが空回りする可能性が少ない状態でガラス基板2を搬送することができる。
Then, substantially the same amount of clean air is supplied from the air conditioning plate 15 to the lower surface 2a of the glass substrate 2 both in the transport direction and in the lateral width direction, and the glass substrate 2 is supported at an approximately constant interval with respect to the air conditioning plate 15. It will be. Therefore, since the air conditioning plate 15 is provided so as to be positioned downward as the side corresponding to the propulsion one end side 2b of the glass substrate 2, the other end side 2c of the glass substrate 2 is positioned above the propulsion one end side 2b. Is supported in a tilted posture. Note that the tilted glass substrate 2 has a slight inclination of about 0.5 ° and is included in a substantially horizontal attitude.
Accordingly, by supporting the glass substrate 2 in an inclined posture, the glass substrate 2 tends to move to the side provided with the propelling force imparting means 4 that is on the lower side in the lateral width direction due to its own weight. The movement is received by the large diameter portion 24 a of the drive roller 24. Therefore, the movement of the glass substrate 2 to one side in the lateral width direction is restricted by the large diameter portion 24a of the driving roller 24, and the glass substrate 2 is less likely to move to the other end side in the lateral width direction of the glass substrate 2 due to its own weight. Therefore, when the glass substrate is braked at the end of conveyance, the glass substrate can be prevented from being displaced in the lateral width direction or being inclined in the conveyance direction. Further, since the glass substrate 2 is pressed against the driving roller 24 by its own weight, the glass substrate 2 can be transported with a low possibility that the driving roller is idle.

参考の実施の形態
上記本発明の実施の形態では、送風式支持手段3にてガラス基板2を傾けた姿勢で支持し、駆動ローラ24に大径部24aを備えることにより、ガラス基板2が横幅方向へ移動することを防止したが、次のように構成して、送風式支持手段3にて水平姿勢で支持したガラス基板2の横幅方向への移動を防止するように構成してもよい。尚、実施の形態1と同様に構成されるものについては、本発明の実施の形態と同じ符号を付け、説明は省略する。
[ Reference Embodiment 1 ]
In the form status of implementation of the present invention, the mobile support in a posture tilted glass substrate 2 at the blower type support means 3, by providing the large diameter portion 24a on the driving roller 24, the glass substrate 2 in the lateral width direction However, the glass substrate 2 supported in a horizontal posture by the blower-type support means 3 may be prevented from moving in the lateral width direction. Incidentally, what is the same structure as the first embodiment, with the shape on purpose same reference numerals of the present invention, description thereof is omitted.

つまり、図10に示すように、ケース体7が、搬送方向視で水平用支持部材37にて水平状態に支持されおり、そのケース体7に支持される送風式支持手段3も水平姿勢で支持されている。よって、清浄空気供給部15も水平姿勢で設けられている。
よって、搬送方向においても横幅方向においても整風板15から略同量の清浄空気がガラス基板2の下面2aに供給されて、ガラス基板2は整風板15に対して略一定の間隔をもって支持されることとなる。よって、整風板15が水平状態に設けられているので、ガラス基板2は水平姿勢で支持されている。
That is, as shown in FIG. 10, the case body 7 is supported in a horizontal state by the horizontal support member 37 when viewed in the transport direction, and the blower-type support means 3 supported by the case body 7 is also supported in a horizontal posture. Has been. Therefore, the clean air supply unit 15 is also provided in a horizontal posture.
Therefore, substantially the same amount of clean air is supplied from the air conditioning plate 15 to the lower surface 2a of the glass substrate 2 both in the transport direction and in the lateral width direction, and the glass substrate 2 is supported at an approximately constant interval with respect to the air conditioning plate 15. It will be. Therefore, since the air conditioning plate 15 is provided in a horizontal state, the glass substrate 2 is supported in a horizontal posture.

そして、搬送空間Aに、ガラス基板2における推進一端側2bとは横幅方向において反対側の他端側2cの側面に接当して、ガラス基板2cの横幅方向への移動を規制する規制部としての多数の規制ローラ33が備えられており、この規制ローラ33のそれぞれは、前記横幅方向に位置調節可能に構成されている。   And as a regulation part which contacts the conveyance space A and the side surface of the other end side 2c opposite to the propulsion one end side 2b in the glass substrate 2 in the width direction, and restricts the movement of the glass substrate 2c in the width direction. A large number of regulating rollers 33 are provided, and each of the regulating rollers 33 is configured to be position-adjustable in the lateral width direction.

前記規制ローラ33の位置調節構造について説明すると、図11に示すように、前記規制ローラ33がローラ支持枠34に縦軸芯周りに回転自在に支持されており、そのローラ支持枠34がユニット用枠体9に載置支持された電動式のモータ35にて横幅方向にスライド移動自在に構成されている。従って、モータ35にてローラ支持体34を横幅方向にスライド移動させることによって、規制ローラ33が横幅方向に位置調節されるように構成されている。そして、前記ローラ支持枠34と送風式支持手段3とが干渉しないように、送風式支持手段3にはローラ支持枠34の縦枠部34aに対応する箇所に凹入部3aを形成してある。   The position adjusting structure of the regulating roller 33 will be described. As shown in FIG. 11, the regulating roller 33 is supported by a roller support frame 34 so as to be rotatable around a vertical axis, and the roller support frame 34 is used for a unit. The electric motor 35 mounted and supported on the frame body 9 is configured to be slidable in the lateral width direction. Therefore, the position of the regulating roller 33 is adjusted in the horizontal width direction by sliding the roller support 34 in the horizontal width direction with the motor 35. In order to prevent the roller support frame 34 and the blower support means 3 from interfering with each other, the blower support means 3 is formed with a recessed portion 3a at a location corresponding to the vertical frame portion 34a of the roller support frame 34.

従って、ガラス基板2の横幅方向の一方側への移動は駆動ローラ24の大径部24aにて規制され、ガラス基板2の横幅方向の他端側への移動は規制ローラ33にて規制されているので、搬送終了時にガラス基板2を制動させる際等に、ガラス基板2が横幅方向にずれてしまったり搬送方向に対して姿勢が斜めになってしまったりすることを防ぐことができる。
そして、図12、図13に示すように、規制ローラ33の横幅方向での位置を調節して、駆動ローラ24の大径部24aと規制ローラ33との間隔をガラス基板2の横幅方向の大きさに合わせることによって、搬送されるガラス基板2が回転したり横幅方向にずれたりすることがなくなり、ガラス基板2の横幅方向の大きさに拘わらず円滑に搬送することができる。
Accordingly, the movement of the glass substrate 2 to one side in the lateral width direction is restricted by the large-diameter portion 24a of the driving roller 24, and the movement of the glass substrate 2 to the other side in the lateral width direction is restricted by the restriction roller 33. Therefore, when the glass substrate 2 is braked at the end of the conveyance, the glass substrate 2 can be prevented from being displaced in the lateral width direction or being inclined in the conveyance direction.
Then, as shown in FIGS. 12 and 13, the position of the regulating roller 33 in the lateral width direction is adjusted so that the distance between the large diameter portion 24 a of the driving roller 24 and the regulating roller 33 is large in the lateral width direction of the glass substrate 2. By adjusting the thickness, the transported glass substrate 2 does not rotate or shift in the lateral width direction, and can be transported smoothly regardless of the size of the glass substrate 2 in the lateral width direction.

参考の実施の形態
上記本発明の実施の形態では、搬送方向視にて、送風式支持手段3を傾斜姿勢に支持して、清浄空気供給部5をガラス基板2の他端側2cに対応する側ほど下方に位置する傾斜姿勢に設けて、ガラス基板2を傾けた姿勢で支持するように構成したが、整風板15を、前記推進力付与手段4にて推進力が付与される推進一端側2bより前記横幅方向の他端側2cの方が清浄空気を多く供給するように設けて、ガラス基板2を前記傾けた姿勢で支持するように構成してもよい。尚、本発明の実施の形態と同様に構成されるものについては、本発明の実施の形態と同じ符号を付け、説明は省略する。

The other end 2c in the lateral width direction may be provided so as to supply more clean air, and the glass substrate 2 may be supported in the inclined posture. Note that those forms on purpose similarly configured embodiment of the present invention, with the shape on purpose same reference numerals of the present invention, description thereof is omitted.

つまり、図14に示すように、前記ケース体7は、搬送方向視にて、水平用支持部材37により水平状態に支持されており、ケース体7が水平状態で支持されることにより、送風式支持手段3も水平姿勢でユニット用枠体9に支持されている。よって、送風式支持手段3に横幅方向に沿って設けられる整風板15も、搬送方向視にて、水平姿勢に設けられている。つまり、送風式支持手段3を含めた搬送ユニット1全体が水平状態に備えられている。   That is, as shown in FIG. 14, the case body 7 is supported in a horizontal state by the horizontal support member 37 when viewed in the conveyance direction, and the case body 7 is supported in the horizontal state, thereby blowing air. The support means 3 is also supported by the unit frame 9 in a horizontal posture. Therefore, the air conditioning plate 15 provided along the lateral width direction on the blower-type support means 3 is also provided in a horizontal posture as viewed in the conveyance direction. That is, the entire transport unit 1 including the blower-type support means 3 is provided in a horizontal state.

そして、送風式支持手段3に備えられる6つの送風ファン13において、横幅方向で推進力付与手段4を備えている側に位置する3つの送風ファン13より、反対側に位置する3つの送風ファン13が速い回転速度で駆動して送風量が多くなるように構成されている。そして、整風板15を、搬送方向視にて横幅方向に並ぶ2つの送風ファンに対して同じ間隔を隔てて設けられている。つまり、送風式支持手段4が、横幅方向に沿って設けられる整風板15を、前記推進一端側2bより横幅方向の他端側2cの方が清浄空気を多く供給するように設けて、ガラス基板2を傾けた姿勢で支持するように構成されている。
要するに、図15に示すように、ガラス基板2の推進一端側2bより他端側2cの方に多くの清浄空気を供給して、ガラス基板2の推進一端側2bより他端側2cを大きく浮き上がらせることによってガラス基板2を傾けた姿勢としている。

The air conditioning plate 15 is provided at the same interval with respect to the two blower fans arranged in the lateral width direction when viewed in the conveyance direction. That is, the air blowing type support means 4 is provided with the air conditioning plate 15 provided along the lateral width direction so that more clean air is supplied to the other end side 2c in the lateral width direction than the propulsion one end side 2b. It is configured to support 2 in a tilted posture.
In short, as shown in FIG. 15, more clean air is supplied from the propulsion one end 2 b of the glass substrate 2 toward the other end 2 c, and the other end 2 c of the glass substrate 2 is lifted more greatly than the propulsion one end 2 b. By doing so, the glass substrate 2 is inclined.

従って、本発明の実施の形態と同様に、ガラス基板2の横幅方向の一方側への移動は駆動ローラ24の大径部24aにて規制され、ガラス基板2の横幅方向の他端側へはガラス基板2の自重によって移動しにくくなるので、搬送終了時にガラス基板2を制動させる際等に、ガラス基板2が横幅方向にずれてしまったり搬送方向に対して姿勢が斜めになってしまったりすることを防ぐことができる。また、ガラス基板2の自重によってガラス基板2が駆動ローラ24に押し付けられるので、駆動ローラ17が空回りする可能性が少ない状態でガラス基板2を搬送することができる。 Accordingly, exemplary forms on purpose likewise of the present invention, movement to one side in the width direction of the glass substrate 2 is restricted by the large diameter portion 24a of the drive roller 24, the lateral width direction of the glass substrate 2 to the other end Since the glass substrate 2 is difficult to move due to its own weight, when the glass substrate 2 is braked at the end of conveyance, the glass substrate 2 is displaced in the horizontal width direction or the posture is inclined with respect to the conveyance direction. Can be prevented. Further, since the glass substrate 2 is pressed against the driving roller 24 by its own weight, the glass substrate 2 can be transported in a state where there is little possibility that the driving roller 17 is idle.
