Description

本発明は、ガラス板の製造方法及び保護シートの分離装置に関する。   The present invention relates to a glass plate manufacturing method and a protective sheet separating apparatus.

ガラス板の製造工程では、合紙、ポリエチレンシート、発泡樹脂シート等の保護シートにガラス板を載せた状態で搬送する工程が含まれる場合がある。このように保護シートを下敷きとしてガラス板を搬送する間に、例えば、ガラス板に対してトリミング(切断処理)等が施される。保護シートは、切断処理の終了後等の所定の段階でガラス板から分離され、ガラス板のみが後続の工程に搬送される。後続の工程では、ガラス板に対して面取りを含む端面加工等の製造関連処理が継続して行われる。   In the manufacturing process of a glass plate, the process of conveying in the state which mounted the glass plate on protective sheets, such as a slip sheet, a polyethylene sheet, and a foamed resin sheet, may be included. Thus, for example, trimming (cutting processing) or the like is performed on the glass plate while the glass plate is conveyed using the protective sheet as an underlay. The protective sheet is separated from the glass plate at a predetermined stage such as after the end of the cutting process, and only the glass plate is conveyed to the subsequent process. In subsequent steps, manufacturing-related processing such as end face processing including chamfering is continuously performed on the glass plate.

ガラス板から保護シートを分離する方法としては、特許文献1に開示の方法が挙げられる。同文献には、保護シート上に載せられたガラス板を搬送ベルトの搬送方向の下流側端部で、搬送ベルトが巻き掛けられたサクションローラ(回転ローラ)によって、搬送ベルトを介して保護シートのみを吸着すると共に下方に引き込み、ガラス板から保護シートを分離することが開示されている。   Examples of the method for separating the protective sheet from the glass plate include the method disclosed in Patent Document 1. In this document, a glass plate placed on a protective sheet is placed at the downstream end in the conveying direction of the conveying belt, and a suction roller (rotating roller) around which the conveying belt is wound is used to pass only the protective sheet through the conveying belt. Is adsorbed and drawn downward to separate the protective sheet from the glass plate.

特開2007−1682号公報JP 2007-1682 A

特許文献1では、サクションローラは、その周壁部の一部に搬送ベルトが巻き掛けられた巻き掛け部を有し、巻き掛け部に対応する位置に生じる負圧吸引力によって保護シートを吸着する。 In Patent Document 1, the suction roller has a winding portion around which a conveyor belt is wound around a part of its peripheral wall portion, and sucks the protective sheet by a negative pressure suction force generated at a position corresponding to the winding portion.

しかしながら、同文献では、サクションローラの周壁部のうち、搬送ベルトが巻き掛けられていない非巻き掛け部側からサクションローラの内部に空気(外気)が流入しやすい構成となっている。そのため、巻き掛け部における負圧吸引力を十分に高めることができず、保護シートの吸着が弱くなりやすい。その結果、ガラス板から保護シートを分離できない事態が生じるおそれがある。   However, in this document, air (outside air) is likely to flow into the suction roller from the non-wrapping portion side around which the conveyance belt is not wound, of the peripheral wall portion of the suction roller. For this reason, the negative pressure suction force at the winding portion cannot be sufficiently increased, and the adsorption of the protective sheet tends to be weak. As a result, there is a possibility that the protective sheet cannot be separated from the glass plate.

本発明は、保護シート上に載せられた状態で搬送されるガラス板から、保護シートを確実に分離することを技術的課題とする。   This invention makes it a technical subject to isolate | separate a protective sheet reliably from the glass plate conveyed in the state mounted on the protective sheet.

上記の課題を解決するために創案された本発明は、保護シート上に載せられたガラス板を搬送する搬送ベルトの下流側端部で、周壁部の一部に搬送ベルトが巻き掛けられた巻き掛け部を有するサクションローラが、搬送ベルトを介して保護シートを吸着することにより、ガラス板から保護シートを分離する工程を含むガラス板の製造方法であって、サクションローラの周壁部のうち、搬送ベルトが巻き掛けられていない非巻き掛け部を囲む仕切り部材を配置し、搬送ベルトと仕切り部材でサクションローラを内部に含む閉断面を形成することを特徴とする。このような構成によれば、サクションローラの周壁部の非巻き掛け部が仕切り部材によって囲まれると共に、搬送ベルトと仕切り部材でサクションローラを内部に含む閉断面が形成されるので、サクションローラの非巻き掛け部側からサクションローラ内に空気が流入する事態を抑制することができる。その結果、巻き掛け部に対応する位置において負圧吸引力を十分発生させることができる。従って、巻き掛け部に対応する位置に生じる負圧吸引力によって保護シートをしっかりと吸着し、ガラス板から保護シートを確実に分離することができる。   The present invention, which was devised to solve the above-described problems, is a winding in which a conveyor belt is wound around a part of a peripheral wall portion at a downstream end portion of a conveyor belt that conveys a glass plate placed on a protective sheet. A suction plate having a hook is a method for producing a glass plate including a step of separating the protective sheet from the glass plate by adsorbing the protective sheet via a conveying belt, and the conveying roller is configured to convey the peripheral wall portion of the suction roller. A partition member surrounding a non-wound portion around which the belt is not wound is disposed, and a closed cross section including a suction roller is formed by the conveyance belt and the partition member. According to such a configuration, the non-winding portion of the peripheral wall portion of the suction roller is surrounded by the partition member, and the closed cross section including the suction roller is formed by the conveyor belt and the partition member. The situation where air flows into the suction roller from the winding part side can be suppressed. As a result, the negative pressure suction force can be sufficiently generated at the position corresponding to the winding portion. Therefore, the protective sheet can be firmly adsorbed by the negative pressure suction force generated at the position corresponding to the winding portion, and the protective sheet can be reliably separated from the glass plate.

上記の構成において、仕切り部材が、非巻き掛け部と間隔を置いて対向配置され、かつ、搬送ベルトのうち、巻き掛け部の上流側に位置する上流側ベルト部位とその下流側に位置する下流側ベルト部位の相互間に掛け渡された第一壁部と、第一壁部の上下両端のそれぞれから搬送ベルトに沿ってサクションローラ側に延びる第二壁部とを備えていることが好ましい。このようにすれば、非巻き掛け部と間隔を置いて第一壁部を設けても、第二壁部によって、巻き掛け部の上流側ベルト部位や下流側ベルト部位を介して空気が流入する事態を抑制することができる。   In the above configuration, the partition member is disposed to face the non-wrapping portion with a space therebetween, and, among the transport belts, the upstream belt portion located upstream of the winding portion and the downstream located downstream thereof. It is preferable to include a first wall portion that is spanned between the side belt portions, and a second wall portion that extends from the upper and lower ends of the first wall portion to the suction roller side along the conveyance belt. If it does in this way, even if it provides a 1st wall part at intervals with a non-wrapping part, air will flow in via a 2nd wall part via an upstream belt part and a downstream belt part of a winding part. The situation can be suppressed.

この場合、仕切り部材が、第一壁部、第二壁部及び非巻き掛け部で囲まれた空間の幅方向両端の開口部を覆う第三壁部を備えていることが好ましい。このようにすれば、第三壁部によって、第二壁部及び非巻き掛け部で囲まれた空間の幅方向両端から空気が流入するのを阻止することができる。   In this case, it is preferable that the partition member includes a third wall portion that covers openings at both ends in the width direction of the space surrounded by the first wall portion, the second wall portion, and the non-wrapping portion. If it does in this way, it can prevent that air flows in from the width direction both ends of the space enclosed by the 2nd wall part and the non-wrapping part by the 3rd wall part.

上記の構成において、第二壁部が、金属製の本体と、第二壁部のサクションローラ側の先端部に、樹脂により形成された樹脂部とを有していてもよい。このようにすれば、第二壁部のサクションローラ側の先端部がサクションローラと接触しても、樹脂部がサクションローラの形状に倣って変形又は摩耗するだけである。そのため、仕切り部材の寸法精度や組み付け精度が不十分であっても、第二壁部をサクションローラと軽く接触させることにより、第二壁部とサクションローラの間から空気が流入するのを抑制できる。   Said structure WHEREIN: The 2nd wall part may have a metal main body and the resin part formed with resin in the front-end | tip part by the side of the suction roller of a 2nd wall part. In this way, even if the tip of the second wall portion on the suction roller side contacts the suction roller, the resin portion only deforms or wears following the shape of the suction roller. Therefore, even if the dimensional accuracy and assembly accuracy of the partition member are insufficient, the inflow of air from between the second wall portion and the suction roller can be suppressed by lightly contacting the second wall portion with the suction roller. .

上記の構成において、仕切り部材側から、仕切り部材と非巻き掛け部の間の空間の空気を吸引することが好ましい。このようにすれば、仕切り部材と非巻き掛け部の間の空間の空気自体も減少するので、非巻き掛け部側からサクションローラ内に流入する空気をより確実に抑制することができる。これにより、巻き掛け部に対応する位置において負圧吸引力を大幅に高めることができる。   Said structure WHEREIN: It is preferable to attract | suck the air of the space between a partition member and a non-wrapping part from a partition member side. If it does in this way, since the air itself of the space between a partition member and a non-wrapping part also reduces, the air which flows in in a suction roller from a non-wrapping part side can be suppressed more reliably. Thereby, the negative pressure suction force can be greatly increased at the position corresponding to the winding portion.

この場合、サクションローラの周壁部に複数の周溝が形成されていることが好ましい。このようにすれば、仕切り部材からサクションローラ側の空気を吸引する際に、周溝内の空気も吸引され、巻き掛け部に対応する位置における負圧吸引力が高まることが期待できる。   In this case, it is preferable that a plurality of peripheral grooves are formed in the peripheral wall portion of the suction roller. In this way, when the air on the suction roller side is sucked from the partition member, the air in the circumferential groove is also sucked, and it can be expected that the negative pressure suction force at the position corresponding to the winding portion is increased.

上記の課題を解決するために創案された本発明は、保護シート上に載せられたガラス板を搬送する搬送ベルトと、搬送ベルトの下流側端部で、周壁部の一部に搬送ベルトが巻き掛けられた巻き掛け部を有するサクションローラとを備え、サクションローラで搬送ベルトを介して保護シートを吸着することにより、ガラス板から保護シートを分離させる保護シートの分離装置であって、サクションローラの周壁部のうち、搬送ベルトが巻き掛けられていない非巻き掛け部を囲む仕切り部材を備え、搬送ベルトと仕切り部材が、サクションローラを内部に含む閉断面を形成していることを特徴とする。このような構成によれば、既に述べた対応する構成と同様の作用効果を奏し得る。   The present invention was devised to solve the above problems. A conveyor belt that conveys a glass plate placed on a protective sheet, and a conveyor belt is wound around a part of the peripheral wall portion at the downstream end of the conveyor belt. A protection sheet separating apparatus for separating a protection sheet from a glass plate by adsorbing the protection sheet via a conveyor belt with the suction roller, A partition member surrounding a non-wrapping portion around which the conveyance belt is not wound is provided in the peripheral wall portion, and the conveyance belt and the partition member form a closed cross section including a suction roller inside. According to such a configuration, the same operational effects as the corresponding configuration already described can be obtained.

以上のような本発明によれば、保護シート上に載せられた状態で搬送されるガラス板から、保護シートを確実に分離することが可能となる。 According to the present invention as described above, it is possible to reliably separate the protective sheet from the glass plate conveyed while being placed on the protective sheet.

以下、本発明の実施形態を図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(第一実施形態)
図1に示すように、第一実施形態に係る保護シートの分離装置1は、製造関連処理ステーションWに配置された搬送手段Cの直上流側に、無端状の搬送ベルト2を備える。
(First embodiment)
As shown in FIG. 1, the protective sheet separating apparatus 1 according to the first embodiment includes an endless conveying belt 2 on the upstream side of the conveying means C disposed in the manufacturing related processing station W.

製造関連処理ステーションWの搬送手段Cは、例えばローラコンベアや搬送ベルト等で構成され、ガラス板Gを矢印Aのように横方向(好ましくは水平方向)に搬送する。本実施形態では、製造関連処理ステーションWは、製造関連処理として、ガラス板Gに対して面取り加工等の端面加工を施すステーションであるが、製造関連処理ステーションWで行う製造関連処理は、端面加工に限定されるものではない。製造関連処理には、端面加工処理の他、切断処理、樹脂フィルム等の積層処理、印刷等の成膜処理等のガラス板Gに直接何らかの加工を施す処理はもちろん、ガラス板Gの洗浄処理やガラス板Gの歪を除去する徐冷処理(熱処理)など、間接的にガラス板Gを最終製品に近づけるための処理が含まれる。   The conveying means C of the manufacturing related processing station W is constituted by, for example, a roller conveyor or a conveying belt, and conveys the glass plate G in the horizontal direction (preferably in the horizontal direction) as indicated by an arrow A. In the present embodiment, the manufacturing related processing station W is a station that performs end face processing such as chamfering on the glass plate G as manufacturing related processing. However, the manufacturing related processing performed in the manufacturing related processing station W is end surface processing. It is not limited to. Manufacturing-related processing includes processing for directly processing the glass plate G such as cutting processing, laminating processing of resin films, film forming processing such as printing, as well as end surface processing processing, cleaning processing of the glass plate G, A treatment for indirectly bringing the glass plate G closer to the final product, such as a slow cooling treatment (heat treatment) for removing the distortion of the glass plate G, is included.

分離装置1の搬送ベルト2は、例えば弾性ゴムからなると共に、計二個の回転ローラ3,4に巻き掛けられている。搬送ベルト2は、回転ローラ3,4の駆動により、保護シートP上に載せられたガラス板Gを矢印aのように横方向(好ましくは水平方向)に搬送する。搬送ベルト2は、その下流側端部で、ガラス板Gを搬送手段Cに移載する。   The conveying belt 2 of the separating device 1 is made of, for example, elastic rubber and is wound around a total of two rotating rollers 3 and 4. The conveyance belt 2 conveys the glass plate G placed on the protective sheet P in the lateral direction (preferably in the horizontal direction) as indicated by an arrow a by driving the rotation rollers 3 and 4. The conveying belt 2 transfers the glass plate G to the conveying means C at its downstream end.

搬送ベルト2が巻き掛けられている二個の回転ローラ3,4のうち、搬送ベルト2の下流側端部に配置された回転ローラ4は、サクションローラである(以下、回転ローラ4をサクションローラという)。サクションローラ4の周壁部4aは、搬送ベルト2が巻き掛けられた巻き掛け部x1と、搬送ベルト2が巻き掛けられていない非巻き掛け部y1とを備える。サクションローラ4は、中空状とされており、その中空部は、巻き掛け部x1に対応する位置で搬送ベルト2に負圧吸引力を発生させるための空気吸引部とされている。サクションローラ4の周壁部4aには、例えばライニングによって硬質ゴムが被覆される。   Of the two rotating rollers 3 and 4 around which the conveying belt 2 is wound, the rotating roller 4 disposed at the downstream end of the conveying belt 2 is a suction roller (hereinafter, the rotating roller 4 is referred to as a suction roller). Called). The peripheral wall 4a of the suction roller 4 includes a winding part x1 around which the transport belt 2 is wound, and a non-winding part y1 around which the transport belt 2 is not wound. The suction roller 4 has a hollow shape, and the hollow portion serves as an air suction portion for generating a negative pressure suction force on the conveyor belt 2 at a position corresponding to the winding portion x1. The peripheral wall 4a of the suction roller 4 is covered with hard rubber by, for example, lining.

搬送ベルト2の内側空間において、非巻き掛け部y1と間隔を置いて対向する位置には、非巻き掛け部y1を囲む仕切り部材5が配置されている。仕切り部材5は、幅方向(搬送方向と直交する方向)に長尺な板状体であり、金属板(例えば鋼板)で構成される。仕切り部材5の上端は、搬送ベルト2のうち、巻き掛け部x1の上流側に位置する上流側ベルト部位2aに近接又は接触しており、仕切り部材5の下端は、搬送ベルト2のうち、巻き掛け部x1の下流側に位置する下流側ベルト部位2bに近接又は接触している。すなわち、仕切り部材5は、上流側ベルト部位2aと下流側ベルト部位2bの相互間に掛け渡されており、搬送ベルト2と仕切り部材5でサクションローラ4を内部に含む閉断面が形成されている。なお、搬送ベルト2のうち、巻き掛け部x1に対応する部分は、保護シートPの搬送方向を変化させる方向変換ベルト部位2cとされる。   In the inner space of the transport belt 2, a partition member 5 surrounding the non-wound portion y1 is disposed at a position facing the non-wound portion y1 with a gap. The partition member 5 is a plate-like body that is long in the width direction (a direction orthogonal to the transport direction), and is configured by a metal plate (for example, a steel plate). The upper end of the partition member 5 is close to or in contact with the upstream belt portion 2 a located on the upstream side of the winding portion x <b> 1 in the transport belt 2, and the lower end of the partition member 5 is wound around the transport belt 2. It is close to or in contact with the downstream belt portion 2b located on the downstream side of the hook portion x1. That is, the partition member 5 is stretched between the upstream belt portion 2a and the downstream belt portion 2b, and a closed cross section including the suction roller 4 inside is formed by the transport belt 2 and the partition member 5. . In addition, the part corresponding to the winding part x1 among the conveyance belts 2 serves as a direction changing belt part 2c that changes the conveyance direction of the protective sheet P.

本実施形態では、仕切り部材5は平板形状であるが、これに限定されない。仕切り部材5は、例えば、サクションローラ4の周壁部4a(周溝4b(後述の図2参照)を除く部分)に倣った部分円筒面形状としてもよい。このようにすれば、仕切り部材5を非巻き掛け部y1に近接配置しやすくなる。   In this embodiment, although the partition member 5 is flat plate shape, it is not limited to this. For example, the partition member 5 may have a partial cylindrical surface shape that follows the peripheral wall portion 4a of the suction roller 4 (a portion excluding the peripheral groove 4b (see FIG. 2 described later)). If it does in this way, it will become easy to arrange partition member 5 near non-winding part y1.

搬送ベルト2の上流側ベルト部位2aの下方には、箱状体6が上流側ベルト部位2aに近接又は接触して配置されている。箱状体6の内部空間は、上流側ベルト部位2aの上面に負圧吸引力を発生させるための空気吸引部とされている。   Below the upstream belt portion 2a of the transport belt 2, a box-like body 6 is disposed in proximity to or in contact with the upstream belt portion 2a. The internal space of the box-shaped body 6 is an air suction portion for generating a negative pressure suction force on the upper surface of the upstream belt portion 2a.

サクションローラ4の中空部及び箱状体6の内部空間は、吸引ホース7を介して真空発生源(不図示)に通じている。本実施形態では、仕切り部材5と非巻き掛け部y1の間の空間s1も吸引ホース7を介して真空発生源に通じている。詳細には、吸引ホース7は、仕切り部材5に設けられた貫通孔(不図示)に接続されており、仕切り部材5側から仕切り部材5と非巻き掛け部y1の間の空間s1の空気が吸引されるようになっている。なお、仕切り部材5と非巻き掛け部y1の間の空間s1は、吸引ホース7を介して真空発生源に通じていなくてもよい。すなわち、空間s1の空気を直接吸引しなくてもよい。負圧吸引力を大幅に高める観点では、仕切り部材5側から仕切り部材5と非巻き掛け部y1の間の空間s1の空気を吸引することが好ましい。   The hollow portion of the suction roller 4 and the internal space of the box-shaped body 6 communicate with a vacuum generation source (not shown) via a suction hose 7. In the present embodiment, the space s1 between the partition member 5 and the non-winding portion y1 also communicates with the vacuum generation source via the suction hose 7. Specifically, the suction hose 7 is connected to a through-hole (not shown) provided in the partition member 5, and air in the space s1 between the partition member 5 and the non-wrapping portion y1 flows from the partition member 5 side. It comes to be sucked. Note that the space s1 between the partition member 5 and the non-winding portion y1 may not communicate with the vacuum generation source via the suction hose 7. That is, the air in the space s1 may not be directly sucked. From the viewpoint of greatly increasing the negative pressure suction force, it is preferable to suck the air in the space s1 between the partition member 5 and the unwound portion y1 from the partition member 5 side.

図2に示すように、搬送ベルト2には全周に亘って複数の貫通孔8が形成され、これらの貫通孔8を通じて負圧吸引力が発生する構成とされている。   As shown in FIG. 2, a plurality of through holes 8 are formed on the entire circumference of the conveyor belt 2, and a negative pressure suction force is generated through these through holes 8.

サクションローラ4の周壁部4aには、複数の周溝4bが形成されると共に、これらの周溝4bの底面壁部には、中空部に通じる複数の貫通孔9がそれぞれ形成されている。サクションローラ4に形成された複数の周溝4bの幅方向における配列ピッチは、搬送ベルト2に形成された複数の貫通孔8の幅方向における配列ピッチと同一に設定されている。   A plurality of peripheral grooves 4b are formed in the peripheral wall portion 4a of the suction roller 4, and a plurality of through holes 9 communicating with the hollow portions are formed in the bottom wall portions of the peripheral grooves 4b. The arrangement pitch in the width direction of the plurality of circumferential grooves 4 b formed in the suction roller 4 is set to be the same as the arrangement pitch in the width direction of the plurality of through holes 8 formed in the conveyor belt 2.

箱状体6の上面壁部6aには、搬送方向に長尺で且つ内部空間に通じる複数のスリット10が並列に形成されている。箱状体6に形成された複数のスリット10の幅方向における配列ピッチは、サクションローラ4に形成された複数の周溝4bの幅方向における配列ピッチと同一に設定されている。従って、スリット10と周溝4bは、それぞれが一列上、つまり全てが複数列状に配列されており、これらは、搬送ベルト2に形成された複数列の貫通孔8の移動軌跡に沿うように配列されている。なお、スリット10に代えて、貫通孔を列状に並べて形成してもよい。   A plurality of slits 10 that are elongated in the transport direction and communicate with the internal space are formed in parallel on the upper surface wall 6a of the box-shaped body 6. The arrangement pitch in the width direction of the plurality of slits 10 formed in the box-like body 6 is set to be the same as the arrangement pitch in the width direction of the plurality of circumferential grooves 4 b formed in the suction roller 4. Accordingly, the slits 10 and the circumferential grooves 4b are each arranged in a line, that is, all are arranged in a plurality of rows, and these are along the movement trajectory of the plurality of rows of through holes 8 formed in the conveyor belt 2. It is arranged. Instead of the slit 10, the through holes may be formed in a line.

周溝4b内の空間は、仕切り部材5と非巻き掛け部y1の間の空間s1と直接的に通じている。なお、周溝4b内の空間は、サクションローラ4の貫通孔9と中空部を介することで、仕切り部材5と非巻き掛け部y1の間の空間s1と間接的にも通じている。   The space in the circumferential groove 4b communicates directly with the space s1 between the partition member 5 and the non-winding portion y1. In addition, the space in the circumferential groove 4b communicates indirectly with the space s1 between the partition member 5 and the non-wrapping portion y1 through the through hole 9 and the hollow portion of the suction roller 4.

次に、以上のように構成された分離装置1を用いたガラス板の製造方法を説明する。   Next, the manufacturing method of the glass plate using the separation apparatus 1 comprised as mentioned above is demonstrated.

図1に示すように、まず、所定サイズにトリミング(切断処理)されたガラス板Gが、保護シートPの上に載せられた状態で、搬送ベルト2上に移載される。搬送ベルト2上への移載は、作業者が手動で、あるいは、搬送ベルト2の更に上流側に配置される搬送手段から自動的に行われる。ガラス板Gの切断処理は、スクライブ工程及び折り割り工程を含む曲げ応力割断によって行われる。   As shown in FIG. 1, first, a glass plate G trimmed to a predetermined size (cutting process) is transferred onto the conveying belt 2 while being placed on the protective sheet P. The transfer onto the conveyor belt 2 is performed manually by an operator or automatically from a conveyor means arranged further upstream of the conveyor belt 2. The cutting process of the glass plate G is performed by bending stress cleaving including a scribe process and a folding process.

移載直後においては、保護シートP及びガラス板Gの先端部は、搬送ベルト2の上流側ベルト部位2aの上流側に位置している。このような状態から、保護シートP及びガラス板Gが搬送ベルト2により下流側に向かって搬送されていく。ここでは常時、上流側ベルト部位2aの複数の貫通孔8から、箱状体6の上面壁部6aに形成された複数のスリット10を通じて、箱状体6の内部空間(空気吸引部)に空気が吸引される。従って、ガラス板Gの下敷きになっている保護シートPが、負圧吸引力によって搬送ベルト2に吸着された状態で、ガラス板Gは搬送ベルト2によって横方向に搬送される。   Immediately after the transfer, the leading ends of the protective sheet P and the glass plate G are located on the upstream side of the upstream belt portion 2 a of the transport belt 2. From such a state, the protective sheet P and the glass plate G are conveyed toward the downstream side by the conveying belt 2. Here, air is constantly introduced into the internal space (air suction portion) of the box-shaped body 6 from the plurality of through holes 8 of the upstream belt portion 2a through the plurality of slits 10 formed in the upper wall 6a of the box-shaped body 6. Is sucked. Accordingly, the glass sheet G is transported in the lateral direction by the transport belt 2 in a state where the protective sheet P under the glass sheet G is attracted to the transport belt 2 by the negative pressure suction force.

この後、搬送ベルト2による横方向の搬送により、保護シートPの先端部が上流側ベルト部位2aを通過し、方向変換ベルト部位2cに達する。ここでも常時、方向変換ベルト部位2cの複数の貫通孔8から、サクションローラ4の複数の周溝4b内及びその底面壁部の貫通孔9を通じて、サクションローラ4の中空部(空気吸引部)に空気が吸引される。この際、サクションローラ4の非巻き掛け部y1側は仕切り部材5によって囲まれると共に、仕切り部材5と非巻き掛け部y1の間の空間s1の空気が仕切り部材5側から吸引される。従って、サクションローラ4の中空部に非巻き掛け部y1側から空気が流入する事態が抑制され、巻き掛け部x1側には高い負圧吸引力が発生する。その結果、保護シートPの先端部は、負圧吸引力によって搬送ベルト2の方向変換ベルト部位2cに確実に吸着された状態で、矢印bのように下方に引き込まれる。一方、ガラス板Gは、搬送ベルト2によって継続して横方向に搬送され、製造関連処理ステーションWの搬送手段Cに移載される。   Thereafter, by the conveyance in the horizontal direction by the conveyance belt 2, the leading end portion of the protective sheet P passes through the upstream belt portion 2a and reaches the direction changing belt portion 2c. Also here, from the plurality of through holes 8 of the direction changing belt portion 2c to the hollow portion (air suction portion) of the suction roller 4 through the plurality of circumferential grooves 4b of the suction roller 4 and the through holes 9 in the bottom wall portion thereof. Air is aspirated. At this time, the non-wrapping portion y1 side of the suction roller 4 is surrounded by the partition member 5, and the air in the space s1 between the partition member 5 and the non-wrapping portion y1 is sucked from the partition member 5 side. Therefore, the situation where air flows into the hollow portion of the suction roller 4 from the non-winding portion y1 side is suppressed, and a high negative pressure suction force is generated on the winding portion x1 side. As a result, the leading end portion of the protective sheet P is pulled downward as indicated by an arrow b in a state where the leading end portion of the protective sheet P is reliably adsorbed to the direction changing belt portion 2c of the transport belt 2 by the negative pressure suction force. On the other hand, the glass plate G is continuously conveyed in the lateral direction by the conveying belt 2 and transferred to the conveying means C of the manufacturing related processing station W.

搬送ベルト2の下流側端部の直下方では、下方に引き込まれた保護シートPに対してノズル11からガス(例えば、空気)が噴射され、保護シートPが搬送ベルト2から剥がされる。本実施形態では、巻き掛け部x1の下流端に対応する方向変換ベルト部位2cの下流端に至る前に、保護シートPが搬送ベルト2から剥がされるが、これに限定されない。例えば、方向変換ベルト部位2cの下流端又はそれ以降の下流側ベルト部位2bで、保護シートPが搬送ベルト2から剥がされるようにしてもよい。   Immediately below the downstream end of the transport belt 2, gas (for example, air) is jetted from the nozzle 11 to the protective sheet P drawn downward, and the protective sheet P is peeled off from the transport belt 2. In the present embodiment, the protective sheet P is peeled off from the transport belt 2 before reaching the downstream end of the direction changing belt portion 2c corresponding to the downstream end of the winding portion x1, but the present invention is not limited to this. For example, the protective sheet P may be peeled off from the transport belt 2 at the downstream end of the direction change belt portion 2 c or the downstream belt portion 2 b after that.

そして、保護シートPの後端部が搬送ベルト2の下流側端部を通過した段階で、搬送ベルト2から引き剥がされた保護シートPが自重により落下して回収箱等に回収されると共に、ガラス板Gは搬送手段Cに完全に移載されて搬送手段Cの動作によって搬送されていく。これにより、保護シートPは、ガラス板Gから完全に分離されて除去される。   And, at the stage where the rear end portion of the protective sheet P has passed the downstream end portion of the conveyor belt 2, the protective sheet P peeled off from the conveyor belt 2 falls by its own weight and is collected in a collection box or the like, The glass plate G is completely transferred to the conveying means C and is conveyed by the operation of the conveying means C. Thereby, the protection sheet P is completely separated from the glass plate G and removed.

(第二実施形態)
図3及び図4に示すように、第二実施形態に係る保護シートの分離装置21、及びガラス板の製造方法が、第一実施形態と相違するところは、仕切り部材22の構成にある。以下では、相違する構成である仕切り部材22を中心に説明し、共通する構成の詳しい説明は省略する。なお、図3及び図4に現れている共通する構成については、第一実施形態と同一符号を付している。
(Second embodiment)
As shown in FIGS. 3 and 4, the protective sheet separating apparatus 21 and the glass plate manufacturing method according to the second embodiment are different from the first embodiment in the configuration of the partition member 22. Below, it demonstrates centering on the partition member 22 which is a different structure, and abbreviate | omits detailed description of a common structure. In addition, about the common structure which appears in FIG.3 and FIG.4, the same code | symbol as 1st embodiment is attached | subjected. As shown in FIGS. 3 and 4, the protective sheet separating apparatus 21 and the glass plate manufacturing method according to the second embodiment are different from the first embodiment in the configuration of the partition member 22. Below, it demonstrates centering on the partition member 22 which is a different structure, and abbreviate | omits detailed description of a common structure. In addition, about the common structure which appears in FIG.3 and FIG.4, the same code | symbol as 1st embodiment is attached |

第二実施形態では、仕切り部材22が、サクションローラ4の非巻き掛け部y1と間隔を置いて対向配置され、かつ、搬送ベルト2の上流側ベルト部位2aと下流側ベルト部位2bの相互間に掛け渡された第一壁部22aと、第一壁部22aの上下両端のそれぞれから搬送ベルト2に沿ってサクションローラ4側に延びる第二壁部(上壁部及び下壁部)22bとを備える。これにより、第二壁部22bに対応する位置で、第二壁部22bによって、上流側ベルト部位2aの貫通孔8及び下流側ベルト部位2bの貫通孔8のそれぞれが塞がれるので、サクションローラ4の巻き掛け部x1側で発生する負圧吸引力を高めることができる。   In the second embodiment, the partition member 22 is disposed so as to face the non-winding portion y1 of the suction roller 4 with a space therebetween, and between the upstream belt portion 2a and the downstream belt portion 2b of the conveyor belt 2. A spanned first wall portion 22a and a second wall portion (upper wall portion and lower wall portion) 22b extending from the upper and lower ends of the first wall portion 22a to the suction roller 4 side along the conveyor belt 2. Prepare. As a result, each of the through hole 8 of the upstream belt portion 2a and the through hole 8 of the downstream belt portion 2b is closed by the second wall portion 22b at a position corresponding to the second wall portion 22b. The negative pressure suction force generated on the side 4 of the winding portion x1 can be increased.

第二壁部22bは、サクションローラ4側の先端部に、幅方向に長尺な樹脂部23を備える。樹脂部23は、例えば、エンジニアリングプラスチックや弾性ゴムなどの樹脂で形成される。樹脂部23を除く仕切り部材22の本体(第一壁部22a及び第二壁部22bの本体)は、金属で形成される。樹脂部23は、例えば、仕切り部材22の本体にねじ等によって固定される。ここで、第二壁部22bの先端部は、サクションローラ4にできるだけ接近させることが望ましい。しかし、第二壁部22bの先端部が金属であると、仕切り部材22の寸法精度や組み付け精度が不十分である場合に、第二壁部22bの先端部とサクションローラ4との接触により、サクションローラ4が損耗するおそれがある。これに対し、第二壁部22bの先端部に樹脂部23を設ければ、仕切り部材22の寸法精度や組み付け精度が不十分であっても、樹脂部23が積極的に変形又は摩耗することから、サクションローラ4の損耗を抑制できる。従って、仕切り部材22の寸法精度や組み付け精度が不十分であっても、負圧吸引力を確保できる。なお、樹脂部23は省略してもよい。あるいは、第二壁部22bの全部又は仕切り部材22の全部を樹脂で形成してもよい。   The second wall portion 22b includes a resin portion 23 that is long in the width direction at the tip portion on the suction roller 4 side. The resin portion 23 is formed of a resin such as engineering plastic or elastic rubber, for example. The main body of the partition member 22 excluding the resin portion 23 (the main body of the first wall portion 22a and the second wall portion 22b) is made of metal. The resin part 23 is fixed to the main body of the partition member 22 with screws or the like, for example. Here, it is desirable that the tip of the second wall portion 22b be as close to the suction roller 4 as possible. However, if the distal end portion of the second wall portion 22b is metal, when the dimensional accuracy and assembly accuracy of the partition member 22 are insufficient, the contact between the distal end portion of the second wall portion 22b and the suction roller 4, The suction roller 4 may be worn out. On the other hand, if the resin portion 23 is provided at the tip of the second wall portion 22b, the resin portion 23 is actively deformed or worn even if the dimensional accuracy and assembly accuracy of the partition member 22 are insufficient. Therefore, the wear of the suction roller 4 can be suppressed. Therefore, even if the dimensional accuracy and assembly accuracy of the partition member 22 are insufficient, the negative pressure suction force can be secured. The resin portion 23 may be omitted. Or you may form all the 2nd wall parts 22b or the whole partition member 22 with resin.

ここで、仕切り部材22側から、仕切り部材22と非巻き掛け部y2の間の空間s2の空気を吸引することが好ましい。 Here, it is preferable to suck air in the space s2 between the partition member 22 and the non-wrapping portion y2 from the partition member 22 side.

(第三実施形態)
図5及び図6に示すように、第三実施形態に係る保護シートの分離装置31、及びガラス板の製造方法が、第一実施形態と相違するところは、仕切り部材32の構成にある。 As shown in FIGS. 5 and 6, the method of manufacturing the protective sheet separating device 31 and the glass plate according to the third embodiment is different from that of the first embodiment in the configuration of the partition member 32. 以下では、相違する構成である仕切り部材32を中心に説明し、共通する構成の詳しい説明は省略する。 In the following, the partition members 32 having different configurations will be mainly described, and detailed description of the common configurations will be omitted. なお、図5及び図6に示されている共通する構成については、第一実施形態と同一符号を付している。 The common configurations shown in FIGS. 5 and 6 are designated by the same reference numerals as those in the first embodiment. (Third embodiment) (Third embodiment)
As shown in FIGS. 5 and 6, the protective sheet separating apparatus 31 and the glass plate manufacturing method according to the third embodiment are different from the first embodiment in the configuration of the partition member 32. Below, it demonstrates centering on the partition member 32 which is a different structure, and abbreviate | omits detailed description of a common structure. In addition, about the common structure shown by FIG.5 and FIG.6, the same code | symbol as 1st embodiment is attached | subjected. As shown in FIGS. 5 and 6, the protective sheet separating apparatus 31 and the glass plate manufacturing method according to the third embodiment are different from the first embodiment in the configuration of the partition member 32. Below, it demonstrates centering on the partition member 32 which is a different structure, and abbreviate | omits detailed description of a common structure. In addition, about the common structure shown by FIG.5 and FIG.6, the same code | symbol as 1st embodiment is attached |

第三実施形態では、仕切り部材32が、サクションローラ4の非巻き掛け部y1と間隔を置いて対向配置され、かつ、搬送ベルト2の上流側ベルト部位2aと下流側ベルト部位2bの相互間に掛け渡された第一壁部32aと、第一壁部32aの上下両端のそれぞれから搬送ベルト2に沿ってサクションローラ4側に延びる第二壁部(上壁部及び下壁部)32bと、第一壁部32a、第二壁部32b及び非巻き掛け部y1で囲まれた空間s3の幅方向両端の開口部を覆う金属製の第三壁部(側壁部)32cとを備える。第三壁部32cのサクションローラ4側の先端部は、サクションローラ4の周壁部4aの形状に倣った円弧状をなす。このようにすれば、仕切り部材32が、サクションローラ4側のみが開口した箱型になるので、サクションローラ4の非巻き掛け部y1側を略隙間なく覆うことができる。従って、サクションローラ4の中空部に非巻き掛け部y1側から空気が流入する事態をより確実に抑制することができる。   In the third embodiment, the partition member 32 is disposed to face the non-winding portion y1 of the suction roller 4 with a space therebetween, and between the upstream belt portion 2a and the downstream belt portion 2b of the conveyor belt 2. A spanned first wall 32a, a second wall (upper wall and lower wall) 32b extending from the upper and lower ends of the first wall 32a to the suction roller 4 side along the conveyor belt 2, and And a metal third wall portion (side wall portion) 32c that covers openings at both ends in the width direction of the space s3 surrounded by the first wall portion 32a, the second wall portion 32b, and the non-winding portion y1. The tip of the third wall portion 32c on the suction roller 4 side has an arc shape that follows the shape of the peripheral wall portion 4a of the suction roller 4. In this way, since the partition member 32 has a box shape in which only the suction roller 4 side is opened, the non-wrapping portion y1 side of the suction roller 4 can be covered without a substantial gap. Therefore, the situation where air flows into the hollow portion of the suction roller 4 from the non-winding portion y1 side can be more reliably suppressed.

ここで、仕切り部材32側から、仕切り部材32と非巻き掛け部y1の間の空間s3の空気を吸引することが好ましい。第二壁部32bの先端部には、図示例のように、樹脂部33を設けてもよいが、樹脂部33を省略してもよい。第三壁部32cの先端部にも樹脂部を設けてもよい。あるいは、第二壁部32bの全部、第三壁部32cの全部又は仕切り部材32の全部を樹脂で形成してもよい。   Here, it is preferable to suck the air in the space s3 between the partition member 32 and the non-winding portion y1 from the partition member 32 side. The resin portion 33 may be provided at the tip of the second wall portion 32b as shown in the drawing, but the resin portion 33 may be omitted. A resin portion may also be provided at the tip of the third wall portion 32c. Or you may form all the 2nd wall parts 32b, all the 3rd wall parts 32c, or all the partition members 32 with resin.

(第四実施形態)
図7に示すように、第三実施形態に係る保護シートの分離装置41は、複数の貫通孔(不図示)を有する搬送ベルト42と、搬送ベルト42が巻き掛けられた計三個の回転ローラ43,44,45とを備える。搬送ベルト42は、回転ローラ43,44,45によって駆動される。回転ローラ43,44,45のうち、回転ローラ44が、サクションローラである(以下、回転ローラ44をサクションローラという)。サクションローラ44の構成は、第一実施形態のサクションローラ4と同様であるので、詳しい説明は省略する。

As shown in FIG. 7, the protective sheet separating apparatus 41 according to the third embodiment includes a conveying belt 42 having a plurality of through holes (not shown), and a total of three rotating rollers around which the conveying belt 42 is wound. 43, 44, 45. The conveyor belt 42 is driven by rotating rollers 43, 44 and 45. Of the rotating rollers 43, 44, 45, the rotating roller 44 is a suction roller (hereinafter, the rotating roller 44 is referred to as a suction roller). Since the configuration of the suction roller 44 is the same as that of the suction roller 4 of the first embodiment, detailed description thereof is omitted. As shown in FIG. 7, the protective sheet separating apparatus 41 according to the third embodiment includes a transmitting belt 42 having a plurality of through holes (not shown), and a total of three rotating conveyor around which the conveying belt 42 is wound. 43, 44, 45. The conveyor belt 42 is driven by rotating coil 43, 44 and 45. Of the rotating coil 43, 44, 45, the rotating roller 44 is a suction roller (hereinafter, the rotating roller 44 is referred to as) a suction roller). Since the configuration of the suction roller 44 is the same as that of the suction roller 4 of the first embodiment, detailed description thereof is omitted.

搬送ベルト42は、サクションローラ44の周壁部44aの巻き掛け部x2の上流側に位置し、搬送方向が横向きの上流側ベルト部位42aと、サクションローラ44の巻き掛け部x2の下流側に位置し、搬送方向が下向きの下流側ベルト部位42bと、サクションローラ44の巻き掛け部x2に対応する位置に位置し、搬送方向を変化させる方向変換ベルト部位42cとを備える。従って、搬送ベルト42の搬送方向は、上流側ベルト部位42aで横方向であり、方向変換ベルト部位42cで横方向から下方向に徐々に方向変換し、下流側ベルト部位42bで下方向となる。   The conveyor belt 42 is located on the upstream side of the winding portion x2 of the peripheral wall portion 44a of the suction roller 44, and is located on the downstream side of the upstream belt portion 42a whose conveyance direction is lateral and the winding portion x2 of the suction roller 44. , A downstream belt portion 42b whose conveyance direction is downward, and a direction changing belt portion 42c that is located at a position corresponding to the winding portion x2 of the suction roller 44 and changes the conveyance direction. Accordingly, the conveying direction of the conveying belt 42 is the lateral direction at the upstream belt portion 42a, gradually changes from the lateral direction to the downward direction at the direction changing belt portion 42c, and becomes the downward direction at the downstream belt portion 42b.

搬送ベルト42の内側空間において、サクションローラ44の非巻き掛け部y2と間隔を置いて対向する位置には、非巻き掛け部y2を囲む仕切り部材46が配置されている。仕切り部材46の上端は、搬送ベルト42の上流側ベルト部位42aに近接又は接触しており、仕切り部材46の下端は、搬送ベルト42の下流側ベルト部位42bに近接又は接触している。すなわち、仕切り部材46は、上流側ベルト部位42aと下流側ベルト部位42bの相互間に掛け渡されており、搬送ベルト42と仕切り部材46でサクションローラ44を内部に含む閉断面が形成されている。なお、仕切り部材46は、上流側ベルト部位42aや下流側ベルト部位42bに沿って延びる壁部(第二壁部に相当)を有していてもよいし、仕切り部材46と非巻き掛け部y2の間の空間s4の幅方向両端の開口部を覆う壁部(第三壁部に相当)を有していてもよい。   In the inner space of the conveyance belt 42, a partition member 46 surrounding the non-wrapping portion y2 is disposed at a position facing the non-winding portion y2 of the suction roller 44 with a gap. The upper end of the partition member 46 is close to or in contact with the upstream belt portion 42 a of the transport belt 42, and the lower end of the partition member 46 is close to or in contact with the downstream belt portion 42 b of the transport belt 42. That is, the partition member 46 is stretched between the upstream belt portion 42 a and the downstream belt portion 42 b, and a closed cross section including the suction roller 44 inside is formed by the transport belt 42 and the partition member 46. . In addition, the partition member 46 may have a wall part (equivalent to a 2nd wall part) extended along the upstream belt part 42a or the downstream belt part 42b, or the partition member 46 and the non-wrapping part y2. You may have the wall part (equivalent to a 3rd wall part) which covers the opening part of the width direction both ends of space s4 between.

上流側ベルト部位42aの下方には、第一箱状体47が配置されおり、下流側ベルト部位42bの内側には、第二箱状体48が配置されている。これらの箱状体47,48の構成は、第一実施形態の箱状体6と実質的に同じであるので、詳しい説明は省略する。   A first box-like body 47 is disposed below the upstream belt portion 42a, and a second box-like body 48 is disposed inside the downstream belt portion 42b. Since the structure of these box-shaped bodies 47 and 48 is substantially the same as the box-shaped body 6 of the first embodiment, a detailed description thereof is omitted.

サクションローラ44の中空部、第一箱状体47の内部空間、第二箱状体48の内部空間及び仕切り部材46と非巻き掛け部y2の間の空間s4は、吸引ホース49を介して真空発生源(不図示)に通じている。なお、仕切り部材46と非巻き掛け部y2の間の空間s4は、吸引ホース49を介して真空発生源に通じていなくてもよい。すなわち、空間s4の空気を直接吸引しなくてもよい。負圧吸引力を大幅に高める観点では、空間s4の空気を吸引することが好ましい。   The hollow portion of the suction roller 44, the internal space of the first box-shaped body 47, the internal space of the second box-shaped body 48, and the space s4 between the partition member 46 and the unwound portion y2 are vacuumed via the suction hose 49. It leads to a generation source (not shown). Note that the space s4 between the partition member 46 and the non-winding portion y2 may not communicate with the vacuum generation source via the suction hose 49. That is, the air in the space s4 may not be directly sucked. From the viewpoint of greatly increasing the negative pressure suction force, it is preferable to suck the air in the space s4.

以上の構成を備えた分離装置41を用いたガラス板の製造方法は、保護シートPが方向変換ベルト部位42cを通過した後、下流側ベルト部位42bに吸着された状態で下方に搬送される点を除けば、上記の実施形態で説明した製造方法と同様である。すなわち、上流側ベルト部位42aの下流側端部で保護シートPから分離されたガラス板Gは、上流側ベルト部位42aによって横方向に搬送され、製造関連処理ステーションWの搬送手段Cに移載される。   The glass plate manufacturing method using the separating apparatus 41 having the above configuration is that the protective sheet P is conveyed downward in a state of being adsorbed by the downstream belt portion 42b after passing through the direction changing belt portion 42c. Is the same as the manufacturing method described in the above embodiment. That is, the glass plate G separated from the protective sheet P at the downstream end of the upstream belt portion 42a is transported laterally by the upstream belt portion 42a and transferred to the transport means C of the manufacturing related processing station W. The

なお、本発明は、上記の実施形態の構成に限定されるものではなく、上記した作用効果に限定されるものでもない。本発明は、本発明の要旨を逸脱しない範囲で種々の変更が可能である。   In addition, this invention is not limited to the structure of said embodiment, It is not limited to an above-described effect. The present invention can be variously modified without departing from the gist of the present invention.

第一〜第三実施形態では、サクションローラの巻き掛け部における搬送ベルトの抱き角(中心角)が約180度である場合を説明し、第四実施形態では、サクションローラの巻き掛け部における搬送ベルトの抱き角(中心角)が約90度である場合を説明したが、サクションローラの巻き掛け部における搬送ベルトの抱き角はこれらに限定されるものではない。例えば、サクションローラの巻き掛け部における搬送ベルトの抱き角は、90度超180度未満であってもよいし、90度未満や180度超であってもよい。   In the first to third embodiments, the case where the holding angle (center angle) of the conveyor belt in the winding portion of the suction roller is about 180 degrees will be described. In the fourth embodiment, the conveyance in the winding portion of the suction roller Although the case where the holding angle (center angle) of the belt is about 90 degrees has been described, the holding angle of the conveying belt in the winding portion of the suction roller is not limited to these. For example, the holding angle of the conveyance belt in the winding portion of the suction roller may be more than 90 degrees and less than 180 degrees, or less than 90 degrees and more than 180 degrees.
