Description

玻璃板製造方法及玻璃板製造裝置Glass plate manufacturing method and glass plate manufacturing device

本發明是有關於一種玻璃板的製造方法及其製造裝置。The present invention relates to a manufacturing method of a glass plate and a manufacturing apparatus thereof.

玻璃板被用於液晶顯示器、有機電致發光（Electroluminescence，EL）顯示器等薄型顯示設備或感測器的基板、或者固體攝像元件或雷射二極體等半導體封裝用蓋體、以及薄膜化合物太陽能電池的基板等。Glass plates are used for thin display devices such as liquid crystal displays and organic electroluminescence (EL) displays, substrates for sensors, or covers for semiconductor encapsulation such as solid-state imaging elements or laser diodes, and thin-film compound solar cells. Substrates of batteries, etc.

於此種玻璃板的製造步驟中，進行如下操作：於將原來的多張玻璃板在與保護片交替積層的狀態下輸送後，自該積層體一張一張地取出玻璃板並搬運至後步驟。作為其具體例，專利文獻1中，揭示了一併將最前排的第一玻璃板與存在於該第一玻璃板的前側的前側保護片利用交接墊吸附保持，並自以傾斜姿勢立靠支撐於托板的背板上的積層體拉開。In the manufacturing process of such a glass plate, after conveying a plurality of original glass plates in a state where they are alternately laminated with protective sheets, the glass plates are taken out from the laminated body one by one and conveyed to the back. step. As a specific example of this, Patent Document 1 discloses that the first glass plate in the frontmost row and the front side protective sheet existing on the front side of the first glass plate are adsorbed and held together by a delivery pad, and are supported by themselves in an inclined posture. Pull apart the laminate on the back panel of the pallet.

詳細而言，該文獻中，於用於消除第一玻璃板的上側角部向保護片的穿刺的穿刺消除墊吸附保持存在於第一玻璃板的後側的後側保護片的上側角部並進行按壓的狀態下，利用交接墊將第一玻璃板及前側保護片同時自積層體拉開。In detail, in this document, the puncture elimination pad for eliminating the puncture of the upper corner of the first glass plate to the protective sheet is adsorbed and held by the upper corner of the rear protective sheet existing on the rear side of the first glass plate, and In the pressed state, the first glass plate and the front side protective sheet are simultaneously pulled away from the laminate by the delivery pad.

進而，該文獻中，為了使穿刺消除墊抵接於後側保護片的上側角部，於利用穿刺消除墊吸附保持後側保護片的上側角部之前，利用掀起墊掀起前側保護片，使後側保護片的上側角部露出。 [現有技術文獻] [專利文獻] Furthermore, in this document, in order to make the puncture elimination pad abut against the upper corner of the rear protective sheet, before the upper corner of the rear protective sheet is adsorbed and held by the puncture elimination pad, the front protective sheet is lifted up by the lifting pad, so that the rear The upper corners of the side protection sheets are exposed. [Prior Art Literature] [Patent Literature]

專利文獻1：日本專利特開2019-104566號公報Patent Document 1: Japanese Patent Laid-Open No. 2019-104566

[發明所欲解決之課題][The problem to be solved by the invention]

專利文獻1中，於利用掀起墊掀起前側保護片時，將掀起墊吸附保持前側保護片的吸附區域設定在與第一玻璃板的上端緣重合（overlap）的位置（於掀起墊的吸附區域的上下方向中間存在第一玻璃板的上端緣的位置）（參照該文獻的段落0034、圖3）。如此，例如於掀起墊的吸附區域的下半部分吸附保持前側保護片的與第一玻璃板的重疊部，於掀起墊的吸附區域的剩餘的上半部分吸附保持前側保護片的自第一玻璃板的伸出部。In Patent Document 1, when the front side protective sheet is lifted by the lift pad, the suction area of the lift pad to suck and hold the front side protective sheet is set at a position overlapping with the upper edge of the first glass plate (at the position of the suction area of the lift pad). A position where the upper end edge of the first glass plate exists in the middle in the vertical direction) (refer to paragraph 0034 and FIG. 3 of this document). In this way, for example, the overlapping portion of the front protective sheet and the first glass plate is adsorbed and held in the lower half of the suction area of the lift pad, and the first glass of the front protective sheet is adsorbed and held in the remaining upper half of the suction area of the lift pad. extension of the plate.

然而，前側保護片的重疊部為沿著第一玻璃板的平面狀，相對於此，前側保護片的伸出部由於無利用第一玻璃板進行的支撐，因此有時具有起伏或傾斜等。即，在前側保護片的重疊部與伸出部之間，片的狀態容易大幅度地變化。因此，如專利文獻1般，於掀起步驟中，僅將單一的吸附墊（掀起墊）的吸附區域設定在與第一玻璃板的上端緣重合的位置，難以同時穩定地保持前側保護片的重疊部及伸出部。而且，若前側保護片的重疊部及伸出部的至少一者產生保持不良，則於掀起前側保護片的過程中，前側保護片會不當地彎曲或鉤掛於其他構件等而有可能無法順利地進行玻璃板的取出作業。However, the overlapping portion of the front side protective sheet is a plane shape along the first glass plate, whereas the overhang portion of the front side protective sheet is not supported by the first glass plate, and therefore may have undulations, inclinations, or the like. That is, between the overlapping portion of the front side protective sheet and the protruding portion, the state of the sheet tends to be largely changed. Therefore, as in Patent Document 1, in the lifting step, only the suction region of a single suction pad (lifting pad) is set at a position overlapping the upper edge of the first glass plate, and it is difficult to stably maintain the overlapping of the front side protective sheets at the same time. part and extension. Furthermore, if at least one of the overlapping portion and the protruding portion of the front side protective sheet is held poorly, in the process of lifting the front side protective sheet, the front side protective sheet may be improperly bent or hooked to other members, which may not be smooth. Take out the glass plate.

本發明的課題是順利地進行玻璃板的取出作業。 [解決課題之手段] The subject of this invention is to perform the take-out operation|work of a glass plate smoothly. [Means of Solving Problems]

為了解決所述課題而首創的本發明為一種玻璃板製造方法，自積層體將最前排的第一玻璃板與第一玻璃板的前側保護片一起依次取出，所述積層體為於前後方向上積層包含傾斜姿勢的玻璃板與傾斜姿勢的保護片且保護片具有自玻璃板伸出的伸出部及與玻璃板重疊的重疊部的積層體，所述玻璃板製造方法的特徵在於包括：掀起步驟，利用掀起用吸附構件掀起前側保護片以使第一玻璃板的後側保護片的伸出部的一部分露出；以及分離步驟，於利用按壓構件按壓在掀起步驟中露出的後側保護片的伸出部的狀態下，利用保持構件將前側保護片與第一玻璃板一起保持並自積層體拉開，掀起用吸附構件具有第一吸附構件與第二吸附構件，於掀起步驟中，利用第一吸附構件吸附保持前側保護片的重疊部，並且利用第二吸附構件吸附保持前側保護片的伸出部。The present invention invented in order to solve the above-mentioned problem is a method for manufacturing a glass plate in which the first glass plate in the frontmost row is sequentially taken out together with the front side protective sheet of the first glass plate from a laminated body in the front-rear direction. A laminated body including a glass plate in an inclined posture and a protective sheet in an inclined posture, wherein the protective sheet has a protruding portion extending from the glass plate and an overlapping portion overlapping the glass plate, and the glass plate manufacturing method is characterized by comprising: lifting up The step is to lift up the front side protection sheet with the lifting suction member to expose a part of the extension of the rear side protection sheet of the first glass plate; and the separation step is to use the pressing member to press the rear side protection sheet exposed in the lifting step. In the state of the protruding portion, the front side protective sheet is held together with the first glass plate by the holding member and pulled away from the laminated body, and the suction member for lifting has a first suction member and a second suction member. In the lifting step, the first suction member is used. An adsorption member adsorbs and holds the overlapping portion of the front protective sheet, and uses a second adsorption member to adsorb and hold the protruding portion of the front protective sheet.

如此，於掀起步驟中，前側保護片的重疊部及伸出部各者分別被第一吸附構件及第二吸附構件吸附保持。即，可根據前側保護片的重疊部的狀態使第一吸附構件的姿勢或吸附力的大小等適當化，並且根據前側保護片的伸出部的狀態使第二吸附構件的姿勢或吸附力的大小等適當化。因此，由於可同時穩定地保持前側保護片的重疊部及伸出部，因此於掀起步驟中，可確實地抑制前側保護片不當地彎曲或鉤掛於其他構件等不良情況。其結果，可於分離步驟中，於利用按壓構件按壓後側保護片的伸出部的狀態下，利用保持構件將第一玻璃板及前側保護片同時順利地自積層體拉開。In this way, in the lifting step, each of the overlapping portion and the extending portion of the front side protective sheet is adsorbed and held by the first adsorption member and the second adsorption member, respectively. That is, the posture of the first suction member, the magnitude of the suction force, etc. can be adjusted according to the state of the overlapping portion of the front protective sheet, and the posture or suction force of the second suction member can be adjusted according to the state of the extension portion of the front protective sheet. Appropriate size, etc. Therefore, since the overlapping portion and the protruding portion of the front side protective sheet can be held stably at the same time, in the lifting step, the front side protective sheet can be reliably prevented from being bent improperly or being hooked on other members. As a result, in the separation step, the first glass plate and the front protective sheet can be smoothly pulled away from the laminate simultaneously by the holding member in a state where the protrusion of the rear protective sheet is pressed by the pressing member.

於所述結構中，較佳為於利用按壓構件按壓後側保護片的伸出部之後、且於利用保持構件保持第一玻璃板及前側保護片並自積層體拉開之前，使吸附保持有前側保護片的第一吸附構件及第二吸附構件返回至於所述掀起步驟中掀起所述前側保護片之前的位置。In the above-mentioned structure, it is preferable that after the protrusion of the rear side protective sheet is pressed by the pressing member, and before the first glass plate and the front side protective sheet are held by the holding member and pulled apart from the laminated body, the suction is held. The first suction member and the second suction member of the front side protection sheet are returned to the positions before the front side protection sheet is lifted in the lifting step.

如此，可於前側保護片相對於第一玻璃板的位置關係難以產生錯亂的狀態下利用保持構件將第一玻璃板及前側保護片同時自積層體拉開。In this way, the first glass plate and the front protective sheet can be simultaneously pulled apart from the laminate by the holding member in a state where the positional relationship of the front protective sheet with respect to the first glass plate is unlikely to be disturbed.

於所述結構中，較佳為於分離步驟中，於利用第一吸附構件及第二吸附構件吸附保持前側保護片且利用保持構件保持第一玻璃板及前側保護片的狀態下，使第一吸附構件、第二吸附構件及保持構件向將前側保護片及第一玻璃板自積層體拉開的方向移動。In the above structure, it is preferable that in the separation step, the first suction member and the second suction member are used to suction and hold the front side protection sheet and the first glass plate and the front side protection sheet are held by the holding member, so that the first The suction member, the second suction member, and the holding member move in a direction in which the front protective sheet and the first glass plate are pulled apart from the laminate.

如此，於將第一玻璃板及前側保護片自積層體拉開時，前側保護片的重疊部與伸出部亦被保持，因此前側保護片相對於第一玻璃板的位置關係更難以產生錯亂。In this way, when the first glass plate and the front protective sheet are pulled apart from the laminate, the overlapping portion and the protruding portion of the front protective sheet are also maintained, so the positional relationship of the front protective sheet relative to the first glass plate is less likely to be confused .

於所述結構中，較佳為第二吸附構件吸附保持前側保護片的保持區域位於較按壓構件按壓後側保護片的按壓區域更靠寬度方向內側的位置。In the above structure, it is preferable that the holding area of the second adsorption member to adsorb and hold the front side protective sheet is located further inward in the width direction than the pressing area of the pressing member pressing the rear side protective sheet.

如此，即使使第二吸附構件向寬度方向內側移動，亦難以與按壓構件發生干涉。因此，掀起步驟等中的第二吸附構件的移動態樣的自由度提高，因此可簡化裝置結構及/或裝置動作。In this way, even if the second suction member is moved inward in the width direction, it is difficult to interfere with the pressing member. Therefore, the degree of freedom of the movement aspect of the second suction member in the lifting step or the like is improved, so that the device structure and/or the device operation can be simplified.

於所述結構中，較佳為第二吸附構件吸附保持的前側保護片的伸出部是自第一玻璃板的上端緣向上側伸出的前側保護片的上端部中位於較第一玻璃板的上側角部更靠寬度方向內側的位置的部分。In the structure, it is preferable that the protruding portion of the front side protection sheet which is adsorbed and held by the second adsorption member is located in the upper end portion of the front side protection sheet which protrudes upward from the upper end edge of the first glass plate and is located at a higher position than the first glass plate. The upper corner portion of , which is closer to the inner side in the width direction.

於較第一玻璃板的上側角部更靠寬度方向外側的位置，第一玻璃板的上端緣對前側保護片的運動（例如向後方的倒塌）的限制變弱，因此片狀態容易變得不穩定。相對於此，於較第一玻璃板的上側角部更靠寬度方向內側的位置，第一玻璃板的上端緣對前側保護片的運動進行了某種程度的限制，因此片狀態容易穩定。因此，第二吸附構件較佳為如所述結構般於較第一玻璃板的上側角部更靠寬度方向內側的位置吸附保持前側保護片的伸出部。藉此，可確實地吸附保持前側保護片的伸出部。At a position further outside in the width direction than the upper corner of the first glass plate, the upper end edge of the first glass plate restricts the movement of the front protective sheet (for example, the collapse to the rear) becomes weaker, so the sheet state tends to become unstable. Stablize. On the other hand, the upper edge of the first glass plate restricts the movement of the front protective sheet to some extent at a position further inward in the width direction than the upper corner of the first glass plate, so that the sheet state is easily stabilized. Therefore, it is preferable that the second suction member suction-holds the protruding portion of the front side protective sheet at a position further inward in the width direction than the upper corner portion of the first glass plate as in the above-mentioned structure. Thereby, the extension part of the front side protective sheet can be reliably adsorbed and held.

於所述結構中，較佳為按壓構件按壓的後側保護片的伸出部是自第一玻璃板的上端緣向上側伸出的後側保護片的上端部中位於較第一玻璃板的上側角部更靠寬度方向內側的位置的部分。In the structure, it is preferable that the protruding portion of the rear side protective sheet pressed by the pressing member is located at a position higher than that of the first glass sheet in the upper end portion of the rear side protective sheet protruding upward from the upper end edge of the first glass sheet. The upper corner portion is a portion located further inward in the width direction.

即，於較第一玻璃板的上側角部更靠寬度方向外側的位置，第一玻璃板的上端緣對後側保護片的運動（例如向前方或向後方的倒塌）的限制變弱，因此片狀態容易變得不穩定。相對於此，於較第一玻璃板的上側角部更靠寬度方向內側的位置，第一玻璃板的上端緣對後側保護片的運動進行了某種程度的限制，因此片狀態容易穩定。因此，按壓構件較佳為如所述結構般於較第一玻璃板的上側角部更靠寬度方向內側的位置按壓後側保護片的伸出部。藉此，可確實地按壓後側保護片的伸出部。That is, the upper edge of the first glass plate restricts the movement of the rear protective sheet (for example, the collapse to the front or the rear) is weaker than the upper corner of the first glass plate in the width direction. Therefore, The sheet state tends to become unstable. On the other hand, the upper edge of the first glass plate restricts the movement of the rear protective sheet to some extent at a position further inward in the width direction than the upper corner of the first glass plate, so that the sheet state is easily stabilized. Therefore, it is preferable that the pressing member presses the protruding portion of the rear protective sheet at a position further inward in the width direction than the upper corner portion of the first glass plate as in the above-described structure. Thereby, the protruding part of the rear side protection sheet can be pressed reliably.

於所述結構中，較佳為於掀起步驟中，於使吸附有第一玻璃板及前側保護片的所述保持構件在固定位置靜止的狀態下，使吸附保持有前側保護片的第一吸附構件及第二吸附構件移動。In the above structure, it is preferable that in the lifting step, in a state in which the holding member on which the first glass plate and the front side protective sheet are adsorbed is stationary at a fixed position, the first adsorption member on which the front side protective sheet is adsorbed is adsorbed and held. The member and the second suction member move.

如此，於掀起前側保護片的期間內，於保持構件的保持區域，第一玻璃板及前側保護片亦被保持於固定位置，兩者的位置關係維持一定。因此，於掀起步驟中，前側保護片相對於第一玻璃板的位置關係難以產生錯亂。In this way, during the period of lifting the front side protection sheet, in the holding area of the holding member, the first glass plate and the front side protection sheet are also held at a fixed position, and the positional relationship between the two is maintained constant. Therefore, in the lifting step, the positional relationship of the front side protective sheet with respect to the first glass plate is unlikely to be disturbed.

如此於在使保持構件在固定位置靜止的狀態下使第一吸附構件及第二吸附構件移動的情況下，較佳為第一吸附構件吸附保持前側保護片的保持區域具有位於較保持構件保持第一玻璃板及前側保護片的保持區域更靠寬度方向外側的位置的部分。In this way, when the first suction member and the second suction member are moved while the holding member is stationary at the fixed position, it is preferable that the holding area of the first suction member suction-holds the front side protective sheet has a position located at a position higher than that of the holding member holding the second suction member. A part of the holding area of the glass plate and the front side protection sheet that is closer to the outer position in the width direction.

如此，即使於利用保持構件使第一玻璃板及前側保護片在固定位置靜止的狀態下，亦容易掀起前側保護片，以使後側保護片的伸出部露出。In this way, even in the state where the first glass plate and the front side protection sheet are stationary at the fixed position by the holding member, the front side protection sheet is easily lifted to expose the protruding portion of the rear side protection sheet.

於所述結構中，較佳為於前側保護片形成通氣用的貫通部，保持構件藉由經由貫通部作用於第一玻璃板的負壓將第一玻璃板與前側保護片一起吸附保持。In the above structure, preferably, a through portion for ventilation is formed in the front protective sheet, and the holding member adsorbs and holds the first glass plate together with the front protective sheet by the negative pressure acting on the first glass plate through the through portion.

如此，無論保護片的材質如何，均可藉由貫通部使保護片具有通氣性。因此，即使使用本來無通氣性的保護片，亦可經由前側保護片確實地吸附保持第一玻璃板。In this way, regardless of the material of the protective sheet, it is possible to impart air permeability to the protective sheet through the penetration portion. Therefore, even if a protective sheet with no air permeability is used, the first glass plate can be surely adsorbed and held via the front protective sheet.

於所述結構中，較佳為按壓構件吸附保持後側保護片。In the structure, preferably, the pressing member adsorbs and holds the rear protective sheet.

如此，可藉由按壓構件確實地按壓後側保護片。In this way, the rear protective sheet can be surely pressed by the pressing member.

於所述結構中，較佳為第一吸附構件及第二吸附構件為吸附墊。In the structure, preferably the first adsorption member and the second adsorption member are adsorption pads.

如此，可確實地吸附保護片及玻璃板此兩者。In this way, both the protective sheet and the glass plate can be reliably adsorbed.

根據本發明，可順利地進行玻璃板的取出作業。According to the present invention, the work of taking out the glass plate can be smoothly performed.

以下，參照隨附圖式說明本發明的實施方式。Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

＜玻璃板製造裝置＞ 圖1是表示本發明的實施方式的玻璃板製造裝置1的側面圖。該圖中的左方向為前方側且右方向為後方向。如該圖所示般，於托板2的底板2a上載置有在前後方向上保護片3與玻璃板4交替積層而成的積層體5。積層體5以傾斜姿勢立靠支撐於托板2的背板2b。因此，保護片3及玻璃板4亦呈傾斜姿勢。 <Glass plate manufacturing equipment> FIG. 1 : is a side view which shows the glass plate manufacturing apparatus 1 which concerns on embodiment of this invention. The left direction in the figure is the front side and the right direction is the rear direction. As shown in this figure, on the bottom plate 2a of the pallet 2, the laminated body 5 in which the protective sheet 3 and the glass plate 4 are laminated|stacked alternately in the front-back direction is mounted. The layered body 5 is supported by the back plate 2b of the pallet 2 in an inclined posture. Therefore, the protective sheet 3 and the glass plate 4 are also inclined.

如圖2所示，保護片3的上端部3a自玻璃板4的上端緣4a向上側伸出，保護片3的寬度方向兩端部3b自玻璃板4的寬度方向兩端緣4b分別向寬度方向外側伸出。即，保護片3中，上端部3a及寬度方向兩端部3b成為自玻璃板4伸出的伸出部。另一方面，保護片3中，除上端部3a及寬度方向兩端部3b以外的部分成為與玻璃板4重疊的重疊部3c。As shown in FIG. 2 , the upper end portion 3 a of the protective sheet 3 protrudes upward from the upper end edge 4 a of the glass plate 4 , and the widthwise end portions 3 b of the protective sheet 3 extend from the widthwise end edge 4 b of the glass plate 4 to the width direction, respectively. Outward direction. That is, in the protective sheet 3, the upper end part 3a and the both ends 3b in the width direction are the extension parts which protrude from the glass plate 4. As shown in FIG. On the other hand, in the protective sheet 3, the part other than the upper end part 3a and the width direction both ends part 3b becomes the overlapping part 3c which overlaps with the glass plate 4.

保護片3的上端部3a的伸出尺寸例如設為40 mm～80 mm，保護片3的寬度方向端部3b的伸出尺寸例如設為40 mm～150 mm。The protruding dimension of the upper end portion 3a of the protective sheet 3 is, for example, 40 mm to 80 mm, and the protruding dimension of the width direction end portion 3b of the protective sheet 3 is, for example, 40 mm to 150 mm.

保護片3設為發泡樹脂片等合成樹脂、紙等。作為發泡樹脂片，例如可使用材質為聚乙烯等且厚度為0.1 mm～0.5 mm、發泡倍率為5倍～20倍者。就抑制褶皺的產生的觀點而言，保護片3較佳為具有伸縮性。The protective sheet 3 is made of synthetic resin such as a foamed resin sheet, paper, or the like. As the foamed resin sheet, for example, a material made of polyethylene or the like, a thickness of 0.1 mm to 0.5 mm, and a foaming ratio of 5 to 20 times can be used. From the viewpoint of suppressing the occurrence of wrinkles, the protective sheet 3 preferably has stretchability.

此處，圖1～圖9中，簡化了保護片3及玻璃板4，但保護片3的上端部3a或寬度方向端部3b亦有時向前側或後側傾倒。於以下的說明中，將積層體5中的最前排的玻璃板4稱為第一玻璃板，將存在於最前排的玻璃板4的前側的保護片3稱為前側保護片，將存在於最前排的玻璃板4的後側的保護片3稱為後側保護片。Here, although the protective sheet 3 and the glass plate 4 are simplified in FIGS. 1-9, the upper end part 3a or the width direction edge part 3b of the protective sheet 3 may fall to the front side or the back side. In the following description, the glass plate 4 in the frontmost row in the laminated body 5 is referred to as a first glass plate, the protective sheet 3 existing on the front side of the glass plate 4 in the frontmost row is referred to as a front-side protective sheet, and the frontmost glass plate 4 is referred to as a front-side protective sheet. The protective sheet 3 on the rear side of the row of glass plates 4 is referred to as a rear protective sheet.

如圖1～圖9所示般，該製造裝置1包括：掀起用吸附構件6，掀起前側保護片3以便成為後側保護片3的伸出部的一部分露出的狀態；按壓構件7，按壓藉由掀起用吸附構件6而露出的後側保護片3的伸出部；保持構件8，將前側保護片3與第一玻璃板4一起保持並自積層體5拉開；以及卡盤9，懸掛支撐藉由保持構件8自積層體5拉開的第一玻璃板4及前側保護片3。As shown in FIGS. 1 to 9 , the manufacturing apparatus 1 includes: a lift-up suction member 6 that lifts up the front side protection sheet 3 so that a part of the protruding portion of the rear side protection sheet 3 is exposed; and a pressing member 7 that presses the The protrusion of the rear side protection sheet 3 exposed by the lifting suction member 6; the holding member 8, which holds the front side protection sheet 3 together with the first glass plate 4 and pulls it away from the laminated body 5; and the chuck 9, which is suspended The first glass plate 4 and the front side protective sheet 3 pulled apart from the laminated body 5 by the holding member 8 are supported.

如圖1、圖3～圖9所示般，掀起用吸附構件6分別包括：第一吸附墊6a，吸附保持前側保護片3的重疊部3c；以及第二吸附墊6b，吸附保持前側保護片3的伸出部。第一吸附墊6a的保持區域與第二吸附墊6b的保持區域相互離開並獨立。As shown in FIGS. 1 , 3 to 9 , the lifting suction members 6 respectively include: a first suction pad 6a for suctioning and holding the overlapping portion 3c of the front protection sheet 3; and a second suction pad 6b for suctioning and holding the front protection sheet 3 extension. The holding area of the first suction pad 6a and the holding area of the second suction pad 6b are separated from each other and independent.

本實施方式中，如圖3所示般，第一吸附墊6a於第一玻璃板4的上側角部4c的附近吸附保持前側保護片3的重疊部3c的上部，第二吸附墊6b於較第一玻璃板4的上側角部4c更靠寬度方向內側的位置，吸附保持前側保護片3的上端部3a。In the present embodiment, as shown in FIG. 3 , the first adsorption pad 6a is in the vicinity of the upper corner 4c of the first glass plate 4 and the upper part of the overlapping portion 3c of the front protection sheet 3 is adsorbed and held, and the second adsorption pad 6b is relatively The upper corner portion 4c of the first glass plate 4 is positioned further inward in the width direction, and the upper end portion 3a of the front side protective sheet 3 is adsorbed and held.

如圖5所示般，第一吸附墊6a及第二吸附墊6b以後側保護片3的上端部3a中形成露出部X的方式掀起前側保護片3，所述露出部X包含位於較第一玻璃板4的上側角部4c更靠寬度方向內側的位置的部分。再者，就抑制前側保護片3相對於第一玻璃板4的位置偏移的觀點而言，較佳為後側保護片3的露出部X的面積小。即，較佳為不會藉由利用第一吸附墊6a及第二吸附墊6b對前側保護片3進行的掀起動作，使後側保護片3的上端部3a的寬度方向中央部露出。於該情況下，露出部X例如成為包含後側保護片3的上側角部的三角形形狀的區域。As shown in FIG. 5 , the first suction pad 6a and the second suction pad 6b lift up the front side protection sheet 3 in such a way that an exposed portion X is formed in the upper end portion 3a of the rear side protection sheet 3, and the exposed portion X includes The upper side corner part 4c of the glass plate 4 is a part of the position further inward in the width direction. Furthermore, it is preferable that the area of the exposed part X of the rear side protection sheet 3 is small from a viewpoint of suppressing the positional displacement of the front side protection sheet 3 with respect to the 1st glass plate 4. That is, it is preferable not to expose the widthwise center portion of the upper end portion 3a of the rear side protection sheet 3 by the lifting operation of the front side protection sheet 3 by the first suction pad 6a and the second suction pad 6b. In this case, the exposed portion X is, for example, a triangular-shaped region including the upper corner portion of the rear side protective sheet 3 .

第一吸附墊6a及第二吸附墊6b於掀起前側保護片3時，於吸附保持有前側保護片3的狀態下，向前方且寬度方向內側傾斜地移動。再者，第一吸附墊6a及第二吸附墊6b的移動方向只要於後側保護片3形成露出部X，則並無特別限定。例如第一吸附墊6a及第二吸附墊6b的移動方向亦可為僅前方、僅下方、僅寬度方向內側、或者包含前方/下方/寬度方向內側中的至少兩個方向的方向。The first suction pad 6a and the second suction pad 6b move obliquely forward and inward in the width direction in a state in which the front protective sheet 3 is sucked and held when the front protective sheet 3 is lifted. In addition, the movement direction of the 1st adsorption|suction pad 6a and the 2nd adsorption|suction pad 6b will not be specifically limited as long as the exposure part X is formed in the rear side protection sheet 3. FIG. For example, the moving direction of the first suction pad 6a and the second suction pad 6b may be only forward, only downward, only widthwise inner side, or a direction including at least two directions of front/downward/widthwise inner side.

如圖6～圖9所示般，按壓構件7包括第三吸附墊7a，所述第三吸附墊7a吸附保持藉由第一吸附墊6a及第二吸附墊6b而露出的後側保護片3的伸出部。As shown in FIGS. 6 to 9 , the pressing member 7 includes a third adsorption pad 7 a that adsorbs and holds the rear side protection sheet 3 exposed by the first adsorption pad 6 a and the second adsorption pad 6 b of the extension.

本實施方式中，第三吸附墊7a於較第一玻璃板4的上側角部4c更靠寬度方向內側的位置吸附保持後側保護片3的上端部3a。In the present embodiment, the third suction pad 7 a suctions and holds the upper end portion 3 a of the rear protective sheet 3 at a position further inward in the width direction than the upper corner portion 4 c of the first glass plate 4 .

如圖1、圖3～圖9所示般，保持構件8包括第四吸附墊8a，所述第四吸附墊8a同時吸附保持第一玻璃板4及前側保護片3的重疊部3c。As shown in FIGS. 1 , 3 to 9 , the holding member 8 includes a fourth adsorption pad 8 a that simultaneously adsorbs and holds the overlapping portion 3 c of the first glass plate 4 and the front protection sheet 3 .

本實施方式中，第四吸附墊8a於較第一吸附墊6a吸附保持前側保護片3的保持區域更靠下方，吸附保持前側保護片3的重疊部3c的上部與第一玻璃板4的上部。In the present embodiment, the fourth suction pad 8a is located below the holding area of the first suction pad 6a, where the front side protection sheet 3 is suctioned and held, and the upper part of the overlapping portion 3c of the front side protection sheet 3 and the upper part of the first glass plate 4 are suctioned and held by the fourth suction pad 8a. .

如圖8所示般，第四吸附墊8a於吸附保持有第一玻璃板4與前側保護片3的狀態下，向前方（或者前方且上方）移動。此時，第一玻璃板4的下端緣4d可與托板2的底板2a接地，亦可自托板2的底板2a離開。As shown in FIG. 8 , the fourth suction pad 8 a moves forward (or forward and upward) in a state in which the first glass plate 4 and the front protection sheet 3 are held by suction. At this time, the lower end edge 4d of the first glass plate 4 can be grounded with the bottom plate 2a of the supporting plate 2, and can also be separated from the bottom plate 2a of the supporting plate 2.

第四吸附墊8a吸附保持第一玻璃板4及前側保護片3的保持區域較第一吸附墊6a吸附保持前側保護片3的保持區域而言大。同樣地，第四吸附墊8a吸附保持第一玻璃板4及前側保護片3的保持區域較第二吸附墊6b吸附保持前側保護片3的保持區域而言大。再者，若為可穩定地搬運第一玻璃板4及前側保護片3的態樣，則各保持區域的大小關係並不限定於此。The holding area of the fourth suction pad 8a to suction and hold the first glass plate 4 and the front side protection sheet 3 is larger than the holding area of the first suction pad 6a to suction and hold the front side protection sheet 3 . Similarly, the holding area of the fourth suction pad 8a to suction and hold the first glass plate 4 and the front protective sheet 3 is larger than the holding area of the second suction pad 6b to suction and hold the front protective sheet 3 . In addition, as long as the 1st glass plate 4 and the front side protective sheet 3 can be conveyed stably, the magnitude|size relationship of each holding area is not limited to this.

如圖8、圖9所示般，卡盤9藉由於交接位置P握持利用第四吸附墊8a搬運的第一玻璃板4及前側保護片3的上端部，而將該些懸掛支撐並搬運至後步驟。交接位置P如圖示例般可為托板2上，亦可為自托板2向前方或側方等離開的位置。As shown in FIGS. 8 and 9 , the chuck 9 holds the upper end portions of the first glass plate 4 and the front side protection sheet 3 conveyed by the fourth suction pad 8 a at the delivery position P, and supports and conveys these suspensions. to the next step. The handover position P may be on the pallet 2 as shown in the example, or may be a position away from the pallet 2 to the front or the side.

此處，圖2～圖7中，圖示了積層體5的寬度方向上的其中一側的半區域，例示了該半區域中的掀起用吸附墊6、按壓構件7及保持構件8的動作。再者，關於積層體5的寬度方向上的另一側的半區域，可以與寬度方向上的其中一側的半區域對稱的方式配置掀起用吸附墊6、按壓構件7及保持構件8。或者，亦可於積層體5的寬度方向上的另一側的半區域配置作業者來代替掀起用吸附墊6等，輔助配置於寬度方向上的其中一側的半區域的掀起用吸附墊6、按壓構件7及保持構件8的動作。Here, in FIGS. 2 to 7 , a half area on one side in the width direction of the layered body 5 is shown, and the operations of the suction pad 6 for lifting, the pressing member 7 , and the holding member 8 in the half area are exemplified. . In addition, the suction pad 6 for lifting, the pressing member 7 and the holding member 8 may be arranged symmetrically with respect to the other half region in the width direction of the layered body 5 so as to be symmetrical with the one half region in the width direction. Alternatively, instead of the suction pads 6 for lifting, etc., an operator may be arranged in the other half area in the width direction of the laminated body 5 to assist the suction pads 6 for lifting arranged in one half area in the width direction. , the action of the pressing member 7 and the holding member 8 .

＜玻璃板製造方法＞ 接著，說明使用了包括所述結構的製造裝置1的玻璃板製造方法。該製造方法依次包括第一按壓步驟、掀起步驟、第二按壓步驟、分離步驟及搬運步驟。 <Method for manufacturing glass plate> Next, the glass plate manufacturing method using the manufacturing apparatus 1 which has the said structure is demonstrated. The manufacturing method sequentially includes a first pressing step, a lifting step, a second pressing step, a separation step and a conveying step.

（第一按壓步驟） 如圖2所示般，第一按壓步驟是如下步驟：利用第三吸附墊7a於較第一玻璃板4的上側角部4c更靠寬度方向內側的位置，吸附保持前側保護片3的伸出部、即上端部3a。藉此，第三吸附墊7a的保持區域的片狀態容易變得穩定，因此可確實地吸附保持前側保護片3的上端部3a。再者，於較第一玻璃板4的上側角部4c更靠寬度方向外側的位置，第一玻璃板4的上端緣4a對前側保護片3的運動的限制變弱，因此與較第一玻璃板4的上側角部4c更靠寬度方向內側的位置相比，片狀態容易變得不穩定。 (first pressing step) As shown in FIG. 2 , the first pressing step is the following step: using the third adsorption pad 7a at a position further inward in the width direction than the upper corner 4c of the first glass plate 4 to adsorb and hold the protrusion of the front side protection sheet 3 part, that is, the upper end part 3a. Thereby, since the sheet state of the holding region of the third suction pad 7a is easily stabilized, the upper end portion 3a of the front side protective sheet 3 can be surely suction-held. Furthermore, the upper edge 4a of the first glass plate 4 has a weaker restriction on the movement of the front side protective sheet 3 than the upper corner portion 4c of the first glass plate 4 is located on the outer side in the width direction. The sheet state tends to become unstable compared to the position inward in the width direction of the upper corner portion 4c of the plate 4 .

（掀起步驟） 如圖3～圖5所示般，掀起步驟是如下步驟：利用第一吸附墊6a及第二吸附墊6b以後側保護片3的上端部3a中位於較第一玻璃板4的上側角部4c更靠寬度方向內側的位置的部分露出的方式掀起前側保護片3。 (lifting steps) As shown in FIGS. 3 to 5 , the lifting step is as follows: using the first adsorption pad 6a and the second adsorption pad 6b, the upper end 3a of the rear protective sheet 3 is located at an upper corner 4c of the first glass plate 4 The front side protective sheet 3 is lifted up so that the part located further inward in the width direction is exposed.

如圖3所示般，於掀起步驟中，於利用第三吸附墊7a吸附保持有前側保護片3的上端部3a的狀態下，利用第一吸附墊6a及第二吸附墊6b吸附保持前側保護片3，且利用第四吸附墊8a吸附保持前側保護片3及第一玻璃板4。As shown in FIG. 3 , in the lifting step, in a state where the upper end portion 3 a of the front protection sheet 3 is adsorbed and held by the third adsorption pad 7 a , the front protection is adsorbed and held by the first adsorption pad 6 a and the second adsorption pad 6 b sheet 3, and the front side protection sheet 3 and the first glass plate 4 are adsorbed and held by the fourth adsorption pad 8a.

詳細而言，第二吸附墊6b於較第一玻璃板4的上側角部4c更靠寬度方向內側的位置吸附保持前側保護片3的上端部3a。藉此，第二吸附墊6b的保持區域的片狀態容易變得穩定，因此可確實地吸附保持前側保護片3的上端部3a。Specifically, the second suction pad 6b suction-holds the upper end portion 3a of the front side protective sheet 3 at a position further inward in the width direction than the upper corner portion 4c of the first glass plate 4 . Thereby, since the sheet state of the holding region of the second suction pad 6b is easily stabilized, the upper end portion 3a of the front side protective sheet 3 can be surely suctioned and held.

第二吸附墊6b吸附保持前側保護片3的保持區域位於較第三吸附墊7a吸附保持前側保護片3（或後側保護片3）的保持區域更靠寬度方向內側的位置。藉此，於掀起步驟中，即使使第二吸附墊6b向寬度方向內側移動，第二吸附墊6b與第三吸附墊7a亦難以相互干涉。The holding area of the second suction pad 6 b sucks and holds the front protective sheet 3 is located further inward in the width direction than the holding area of the third suction pad 7 a sucks and holds the front protective sheet 3 (or the rear protective sheet 3 ). This makes it difficult for the second suction pad 6b and the third suction pad 7a to interfere with each other even if the second suction pad 6b is moved inward in the width direction in the lifting step.

第一吸附墊6a吸附保持前側保護片3的保持區域具有位於較第四吸附墊8a吸附保持第一玻璃板4及前側保護片3的保持區域更靠寬度方向外側的位置的部分。藉此，第一吸附墊6a可於較第四吸附墊8a更靠寬度方向外側的位置吸附保持前側保護片3。因此，於掀起步驟中，即使於使吸附保持有第一玻璃板4及前側保護片3的第四吸附墊8a在固定位置靜止的狀態下，亦容易使第一吸附墊6a向寬度方向內側移動來掀起前側保護片3。再者，本實施方式中，第二吸附墊6b吸附保持前側保護片3的保持區域位於較第一吸附墊6a吸附保持前側保護片3的保持區域更靠寬度方向內側的位置。The holding area of the first suction pad 6a sucking and holding the front protective sheet 3 has a portion located on the outer side in the width direction than the holding area of the fourth suction pad 8a sucking and holding the first glass plate 4 and the front protective sheet 3 . Thereby, the first suction pad 6a can suction and hold the front side protection sheet 3 at a position further outside in the width direction than the fourth suction pad 8a. Therefore, in the lifting step, even when the fourth suction pad 8a holding the first glass plate 4 and the front side protective sheet 3 is held still at the fixed position, the first suction pad 6a can be easily moved inward in the width direction to lift the front side protection sheet 3. Furthermore, in the present embodiment, the holding area of the second suction pad 6b suction-holding the front protection sheet 3 is positioned more inward in the width direction than the holding area of the first suction pad 6a suction and holding the front protection sheet 3 .

如圖4所示，於掀起步驟中，於利用第一吸附墊6a、第二吸附墊6b及第四吸附墊8a進行的吸附保持完成的階段，第三吸附墊7a解除前側保護片3的吸附保持而自前側保護片3離開。As shown in FIG. 4 , in the lifting step, the third suction pad 7a releases the suction of the front side protection sheet 3 at the stage where the suction and holding by the first suction pad 6a, the second suction pad 6b and the fourth suction pad 8a are completed. Hold and leave from the front side protective sheet 3 .

如圖5所示，於掀起步驟中，於第三吸附墊7a離開後，於使吸附保持有前側保護片3及第一玻璃板4的第四吸附墊8a在固定位置靜止的狀態下，使吸附保持有前側保護片3的第一吸附墊6a及第二吸附墊6b移動。藉此，以後側保護片3的上端部3a中位於較第一玻璃板4的上側角部4c更靠寬度方向內側的位置的部分露出的方式掀起前側保護片3。其結果，於後側保護片3中形成露出部X。如此，前側保護片3的重疊部3c及上端部3a分別被第一吸附墊6a及第二吸附墊6b吸附保持。即，可根據前側保護片3的重疊部3c的狀態使第一吸附墊6a的姿勢或吸附力的大小等適當化，並且根據前側保護片3的上端部3a的狀態使第二吸附墊6b的姿勢或吸附力的大小等適當化。因此，由於可同時穩定地保持前側保護片3的重疊部3c及上端部3a，因此於掀起步驟中，可確實地抑制前側保護片3不當地彎曲或鉤掛於其他構件等不良情況。As shown in FIG. 5 , in the lifting step, after the third suction pad 7a is separated, the fourth suction pad 8a on which the front side protective sheet 3 and the first glass plate 4 are suctioned and held is kept at a fixed position, and the The first suction pad 6a and the second suction pad 6b on which the front side protective sheet 3 is held by suction are moved. Thereby, the front side protection sheet 3 is lifted up so that the part located in the width direction inner side of the upper end part 3a of the rear side protection sheet 3 rather than the upper side corner part 4c of the 1st glass plate 4 is exposed. As a result, the exposed portion X is formed in the rear protective sheet 3 . In this way, the overlapping portion 3c and the upper end portion 3a of the front side protective sheet 3 are sucked and held by the first suction pad 6a and the second suction pad 6b, respectively. That is, according to the state of the overlapping portion 3c of the front side protection sheet 3, the posture of the first suction pad 6a, the magnitude of the suction force, etc. can be adjusted, and the second suction pad 6b can be adjusted according to the state of the upper end portion 3a of the front side protection sheet 3. The posture and the size of the suction force are appropriate. Therefore, since the overlapping portion 3c and the upper end portion 3a of the front protective sheet 3 can be held stably at the same time, in the lifting step, the front protective sheet 3 can be reliably prevented from being bent improperly or hooked to other members.

（第二按壓步驟） 如圖6所示般，第二按壓步驟是如下步驟：利用第三吸附墊7a於較第一玻璃板4的上側角部4c更靠寬度方向內側的位置吸附保持露出的後側保護片3的上端部3a並進行按壓。 (Second pressing step) As shown in FIG. 6 , the second pressing step is a step of adsorbing and holding the exposed rear protective sheet 3 at a position further inward in the width direction than the upper corner 4 c of the first glass plate 4 by the third adsorption pad 7 a. The upper end portion 3a is pressed.

本實施方式中，如圖7所示般，第三吸附墊7a吸附保持後側保護片3的上端部3a並進行按壓後，於維持該狀態的情況下，使吸附保持有前側保護片3的第一吸附墊6a及第二吸附墊6b返回原來的位置。藉由該動作，吸附保持有後側保護片3的第三吸附墊7a如圖中虛線所示般，有時會隱藏於前側保護片3的後側。In the present embodiment, as shown in FIG. 7 , after the third suction pad 7 a suctions and holds the upper end portion 3 a of the rear side protection sheet 3 and presses it, the third suction pad 7 a suctions and holds the upper end portion 3 a of the front side protection sheet 3 while maintaining this state. The first suction pad 6a and the second suction pad 6b return to their original positions. By this operation, the third suction pad 7 a holding the rear protective sheet 3 may be hidden behind the front protective sheet 3 as shown by the dotted line in the figure.

（分離步驟） 如圖8所示般，分離步驟是將第一玻璃板4及前側保護片3自積層體5拉開的步驟。 (separation step) As shown in FIG. 8 , the separation step is a step of pulling the first glass plate 4 and the front side protective sheet 3 away from the laminate 5 .

詳細而言，於分離步驟中，於利用第三吸附墊7a吸附保持後側保護片3的上端部3a並進行按壓的狀態下，使吸附保持有第一玻璃板4及前側保護片3的第四吸附墊8a移動。藉此，將第一玻璃板4及前側保護片3自積層體5拉開。Specifically, in the separation step, in a state where the upper end portion 3 a of the rear protective sheet 3 is adsorbed and held by the third adsorption pad 7 a and pressed, the second glass plate 4 and the front protective sheet 3 are adsorbed and held by the third adsorption pad 7 a. The four suction pads 8a move. Thereby, the 1st glass plate 4 and the front side protection sheet 3 are pulled apart from the laminated body 5.

本實施方式中，於將第一玻璃板4及前側保護片3自積層體5拉開時，吸附保持有前側保護片3的第一吸附墊6a及第二吸附墊6b亦與第四吸附墊8a一起向相同方向移動。即，於利用第四吸附墊8a搬運第一玻璃板4及前側保護片3時，前側保護片3被第一吸附墊6a及第二吸附墊6b輔助性地吸附保持。藉此，可同時將第一玻璃板4及前側保護片3順利地自積層體5拉開。In this embodiment, when the first glass plate 4 and the front protective sheet 3 are pulled away from the laminate 5 , the first adsorption pad 6 a and the second adsorption pad 6 b on which the front protective sheet 3 is held are also adsorbed and held by the fourth adsorption pad. 8a move together in the same direction. That is, when the 1st glass plate 4 and the front side protective sheet 3 are conveyed by the 4th adsorption|suction pad 8a, the front side protective sheet 3 is adsorbed and held by the 1st adsorption|suction pad 6a and the 2nd adsorption|suction pad 6b auxiliary. Thereby, the 1st glass plate 4 and the front side protective sheet 3 can be pulled away from the laminated body 5 smoothly at the same time.

（搬運步驟） 如圖9所示般，搬運步驟是藉由卡盤9握持第一玻璃板4及前側保護片3進行搬運的步驟。 (transportation procedure) As shown in FIG. 9 , the conveyance step is a step of conveying while holding the first glass plate 4 and the front side protective sheet 3 by the chuck 9 .

於搬運步驟中，利用第一吸附墊6a、第二吸附墊6b及第四吸附墊8a將第一玻璃板4及前側保護片3搬運至交接位置P。於交接位置P，利用卡盤9握持被第四吸附墊8a吸附保持的第一玻璃板4及前側保護片3的上端部。藉此，第一玻璃板4及前側保護片3被交接至卡盤9。於該交接完成後，利用卡盤9將第一玻璃板4及前側保護片3搬運至後步驟。In the conveyance step, the first glass plate 4 and the front protection sheet 3 are conveyed to the delivery position P by the first suction pad 6a, the second suction pad 6b, and the fourth suction pad 8a. At the delivery position P, the upper end portions of the first glass plate 4 and the front side protection sheet 3 that are adsorbed and held by the fourth adsorption pad 8 a are held by the chuck 9 . Thereby, the first glass plate 4 and the front side protective sheet 3 are delivered to the chuck 9 . After the transfer is completed, the first glass plate 4 and the front side protective sheet 3 are transported to the next step by the chuck 9 .

於所述交接位置P處的交接時，第二吸附墊6b的吸附保持於利用卡盤9握持第一玻璃板4及前側保護片3的上端部之前被解除。另一方面，第一吸附墊6a及第四吸附墊8a的吸附保持於利用卡盤9握持第一玻璃板4及前側保護片3的上端部之後被解除。即，第二吸附墊6b的吸附保持較第一吸附墊6a的吸附保持而言先被解除。藉此，於利用卡盤9握持之前，藉由前側保護片3的彈性，減少前側保護片3的上端部的褶皺。再者，若於產生褶皺的狀態下直接利用卡盤9握持前側保護片3的上端部，則有可能於後步驟中發生作為不良情況的原因的前側保護片3的破損等。During the delivery at the delivery position P, the suction and holding of the second suction pad 6b is released before the upper end portions of the first glass plate 4 and the front side protection sheet 3 are gripped by the chuck 9 . On the other hand, the suction holding of the first suction pad 6 a and the fourth suction pad 8 a is released after the upper end portions of the first glass plate 4 and the front side protection sheet 3 are gripped by the chuck 9 . That is, the suction holding of the second suction pad 6b is released earlier than the suction holding of the first suction pad 6a. Thereby, before being gripped by the chuck 9 , the wrinkle of the upper end portion of the front side protection sheet 3 is reduced by the elasticity of the front side protection sheet 3 . Furthermore, if the upper end portion of the front side protective sheet 3 is directly held by the chuck 9 in a wrinkled state, there is a possibility that the front side protective sheet 3 may be damaged or the like in a later step, which may cause problems.

再者，卡盤9於後步驟中將前側保護片3與第一玻璃板4交接至姿勢變換裝置（省略圖示）。姿勢變換裝置以成為於前側保護片3上載置有第一玻璃板4的水平姿勢的方式進行姿勢變換，之後交接至搬運輸送機。然後，於在前側保護片3上載置有第一玻璃板4的狀態下，執行對第一玻璃板4施加劃線的步驟與沿著該劃線進行折疊的步驟。之後，使前側保護片3自第一玻璃板4離開，對第一玻璃板4進行端面加工或清洗等。In addition, the chuck 9 transfers the front side protective sheet 3 and the first glass plate 4 to a posture changing device (not shown) in a subsequent step. The posture changing device changes the posture so as to have a horizontal posture in which the first glass plate 4 is placed on the front protective sheet 3, and then transfers it to the conveying conveyor. Then, in a state where the first glass plate 4 is placed on the front side protective sheet 3, the step of applying a scribe line to the first glass plate 4 and the step of folding along the scribe line are performed. After that, the front side protective sheet 3 is separated from the first glass plate 4 , and the first glass plate 4 is subjected to end surface processing, cleaning, or the like.

對後續的玻璃板4及保護片3亦同樣地進行如以上般的動作。如此，執行玻璃板4的製造線中的取出至清洗等為止的各步驟。The above-mentioned operations are similarly performed for the subsequent glass plate 4 and the protective sheet 3 . In this way, each step from taking out to washing and the like in the manufacturing line of the glass plate 4 is performed.

＜第四吸附墊＞ 如圖10及圖11所示般，第四吸附墊8a包括基座部11及裙部12。基座部11包括基座主體13、以及自基座主體13延伸的接頭（adapter）14。於接頭14形成有用於傳遞作用於通氣路徑的負壓的通孔14a，於基座主體13形成有與通孔14a連通的貫通孔13a。 <The fourth suction pad> As shown in FIGS. 10 and 11 , the fourth adsorption pad 8 a includes a base portion 11 and a skirt portion 12 . The base portion 11 includes a base body 13 and an adapter 14 extending from the base body 13 . The joint 14 is formed with a through hole 14 a for transmitting the negative pressure acting on the ventilation path, and the base body 13 is formed with a through hole 13 a communicating with the through hole 14 a.

裙部12由矽、腈基丁二烯橡膠（Nitrile Butadiene Rubber，NBR）等可撓性材料形成，自基座主體13呈碗狀延伸，在基座主體13的相反側形成開口端面12a。基座主體13及裙部12形成用於供第四吸附墊8a作用抽吸力的凹陷狀內表面15。The skirt 12 is formed of flexible materials such as silicon and Nitrile Butadiene Rubber (NBR), extends from the base body 13 in a bowl shape, and forms an open end surface 12 a on the opposite side of the base body 13 . The base body 13 and the skirt 12 form a concave inner surface 15 for the fourth suction pad 8a to act as a suction force.

第四吸附墊8a更包括穿孔用的突起16。突起16自凹陷狀內表面15向開口端面12a延伸。突起16較佳為設為超硬合金等硬度高的金屬製品。The fourth suction pad 8a further includes protrusions 16 for perforation. The protrusion 16 extends from the concave inner surface 15 toward the opening end surface 12a. The protrusions 16 are preferably made of a metal product with high hardness such as cemented carbide.

如圖11所示般，於使第四吸附墊8a抵接在與第一玻璃板4重疊的前側保護片3的狀態下，在自真空源（省略圖示）向第四吸附墊8a作用負壓時，前側保護片3被抽吸至第四吸附墊8a的凹陷狀內表面15側。然後，藉由越過突起16的前端部進行抽吸，而於前側保護片3形成通氣用的貫通部H。貫通部H貫通前側保護片3的表背面而形成，結果抽吸力有效地作用於第一玻璃板4。於如此進行抽吸時，來自真空源的負壓經由貫通部H作用於第一玻璃板4，第一玻璃板4與前側保護片3一起被第四吸附墊8a吸附保持。As shown in FIG. 11 , in a state where the fourth suction pad 8 a is brought into contact with the front side protective sheet 3 overlapping the first glass plate 4 , a negative force is applied to the fourth suction pad 8 a from a vacuum source (not shown) During pressing, the front side protective sheet 3 is sucked to the concave inner surface 15 side of the fourth suction pad 8a. Then, by suctioning over the front end portion of the protrusion 16 , the penetration portion H for ventilation is formed in the front side protective sheet 3 . The penetration portion H is formed to penetrate the front and back surfaces of the front-side protective sheet 3 , and as a result, the suction force effectively acts on the first glass plate 4 . When suction is performed in this way, the negative pressure from the vacuum source acts on the first glass plate 4 through the penetration portion H, and the first glass plate 4 is adsorbed and held by the fourth adsorption pad 8 a together with the front side protection sheet 3 .

再者，本發明並不限定於所述實施方式的結構，亦不限定於所述作用效果。本發明可於不脫離本發明的主旨的範圍內進行各種變更。In addition, this invention is not limited to the structure of the said embodiment, nor is it limited to the said effect. In the present invention, various modifications can be made without departing from the gist of the present invention.
