Description

桌台Table

本發明是有關於一種用於在對玻璃板進行規定的處理時載置玻璃板的桌台。The present invention relates to a table for placing a glass plate when the glass plate is subjected to prescribed treatment.

於玻璃板的製造步驟中，包括將玻璃板切斷成規定尺寸的切斷步驟、或對玻璃板的經切斷的端面實施倒角等精加工的端面加工步驟。The manufacturing process of the glass plate includes a cutting process of cutting the glass plate into a predetermined size, or an end surface processing process of performing a finishing process such as chamfering on the cut end surface of the glass plate.

進而，於玻璃板的製造步驟中，亦存在如下情況，即於切斷步驟或端面加工步驟之後，實施對包含玻璃板的尺寸或角部的直角度等的玻璃板的形狀資料進行測定的形狀測定步驟。Furthermore, in the manufacturing process of the glass plate, there is also a case where a shape measuring step is performed after the cutting step or the end surface processing step to measure shape data of the glass plate including the size of the glass plate or the right angle of the corners.

為了對玻璃板準確地進行所述各種加工或測定等處理，必須於各處理時對玻璃板進行定位。In order to accurately perform the above-mentioned various processing or measurement processes on the glass plate, the glass plate must be positioned during each process.

因此，例如於專利文獻1中揭示有於玻璃板的形狀測定時，將玻璃板載置於氟樹脂板上後，使玻璃板於氟樹脂板上滑動，藉此對玻璃板進行定位。 [現有技術文獻] [專利文獻]Therefore, for example, Patent Document 1 discloses that when measuring the shape of a glass plate, the glass plate is placed on a fluororesin plate and then slid on the fluororesin plate to position the glass plate. [Prior Art Document] [Patent Document]

專利文獻1：日本專利特開2003-75121號公報Patent document 1: Japanese Patent Publication No. 2003-75121

[發明所欲解決之課題] 於專利文獻1中，將尺寸比較小的光罩用的方形的玻璃板作為對象，但假設於應用於正不斷大尺寸化的平板顯示器用的玻璃基板等的情況下，必須使用大尺寸的氟樹脂板，因此無法避免成本上昇。[Problems to be solved by the invention] In patent document 1, a relatively small square glass plate for a photomask is used as the object, but if it is applied to a glass substrate for a flat panel display, which is becoming larger and larger, a large fluororesin plate must be used, and thus a cost increase is inevitable.

本發明將即便是大尺寸的玻璃板，亦容易且低成本地實現玻璃板的定位作為課題。 [解決課題之手段]The present invention aims to realize the positioning of a glass plate easily and at low cost even for a large-sized glass plate. [Means for solving the problem]

為了解決所述課題而創造的本發明是一種桌台，其為了對玻璃板進行規定的處理而具有載置玻璃板的載置部，載置部包括：第一凸條部，與玻璃板的接觸部沿著第一方向為長尺寸；及第二凸條部，與玻璃板的接觸部沿著與第一方向不同的第二方向為長尺寸。The present invention created to solve the above-mentioned problem is a table having a placing portion for placing a glass plate in order to perform prescribed processing on the glass plate, the placing portion comprising: a first ridge portion, the contact portion with the glass plate being long along a first direction; and a second ridge portion, the contact portion with the glass plate being long along a second direction different from the first direction.

根據此種結構，玻璃板由載置部的第一凸條部及第二凸條部支持。第一凸條部的接觸部沿著第一方向而細長，因此當使玻璃板沿著第一方向移動時，第一凸條部相對於玻璃板不變成大的阻力。因此，可於利用第一凸條部支持玻璃板的狀態下，使玻璃板於第一方向上順利地移動。同樣地，第二凸條部的接觸部沿著第二方向而細長，因此當使玻璃板沿著第二方向移動時，第二凸條部相對於玻璃板不變成大的阻力。因此，可於利用第二凸條部支持玻璃板的狀態下，使玻璃板於第二方向上順利地移動。因此，可於利用第一凸條部及第二凸條部支持玻璃板的狀態下，使玻璃板於不同的兩個方向上順利地移動，因此可容易地對玻璃板進行定位。另外，與以面支持玻璃板的的整個面的情況相比，第一凸條部及第二凸條部可充分減小支持面積，因此即便於支持大尺寸的玻璃板的情況下，亦可抑制伴隨支持面積的擴大的成本上昇。According to this structure, the glass plate is supported by the first ridge portion and the second ridge portion of the mounting portion. The contact portion of the first ridge portion is elongated along the first direction, so when the glass plate is moved along the first direction, the first ridge portion does not become a large resistance to the glass plate. Therefore, the glass plate can be smoothly moved in the first direction while the glass plate is supported by the first ridge portion. Similarly, the contact portion of the second ridge portion is elongated along the second direction, so when the glass plate is moved along the second direction, the second ridge portion does not become a large resistance to the glass plate. Therefore, the glass plate can be smoothly moved in the second direction while the glass plate is supported by the second ridge portion. Therefore, the glass plate can be smoothly moved in two different directions while the glass plate is supported by the first ridge portion and the second ridge portion, so the glass plate can be easily positioned. Furthermore, compared with the case where the entire surface of the glass plate is supported, the first ridge portion and the second ridge portion can sufficiently reduce the supporting area, so even when supporting a large-sized glass plate, the cost increase associated with the increase in the supporting area can be suppressed.

於所述結構中，較佳為玻璃板呈矩形形狀，且第一凸條部的接觸部沿著玻璃板的相向的一對邊延長，第二凸條部的接觸部沿著玻璃板的相向的另一對邊延長。In the structure, it is preferred that the glass plate is rectangular in shape, the contact portion of the first ridge portion extends along a pair of opposite sides of the glass plate, and the contact portion of the second ridge portion extends along another pair of opposite sides of the glass plate.

若如此設定，則第一方向與玻璃板的相向的一對邊實質上平行，第二方向與玻璃板的相向的另一對邊實質上平行。因此，可使玻璃板於沿著各邊的方向上順利地移動，因此玻璃板的定位變得更容易。If so configured, the first direction is substantially parallel to a pair of opposite sides of the glass plate, and the second direction is substantially parallel to another pair of opposite sides of the glass plate. Therefore, the glass plate can be smoothly moved in directions along each side, so that positioning of the glass plate becomes easier.

於所述結構中，較佳為載置部進而包括支持玻璃板的球狀輥。In the above structure, it is preferred that the mounting portion further includes a spherical roller for supporting the glass plate.

若如此設定，則玻璃板於載置部上的移動變得更順利。If so configured, the glass plate can move more smoothly on the mounting portion.

於所述結構中，較佳為第一凸條部的接觸部及第二凸條部的接觸部由樹脂形成。In the above structure, it is preferred that the contact portion of the first ridge portion and the contact portion of the second ridge portion are formed of resin.

若如此設定，則玻璃板的滑動變得良好，因此玻璃板難以破損。 [發明的效果]If this is done, the glass plate will slide well and will be less likely to break. [Effect of the invention]

根據本發明，即便是大尺寸的玻璃板，亦可容易且低成本地實現玻璃板的定位。According to the present invention, even a large-sized glass plate can be positioned easily and at low cost.

以下，參照隨附圖式對本發明的實施方式進行說明。再者，圖中的XYZ是正交座標系。X方向及Y方向為水平方向，Z方向為垂直方向。Hereinafter, the embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, XYZ in the drawings is an orthogonal coordinate system. The X direction and the Y direction are horizontal directions, and the Z direction is a vertical direction.

如圖1所示，本實施方式的玻璃板測定裝置1是用於測定矩形形狀的玻璃板G的形狀資料的裝置。於本實施方式中，玻璃板測定裝置1測定作為形狀資料的玻璃板G的至少一個端面Ga～端面Gd的真直度、玻璃板G的縱橫尺寸（X方向尺寸及Y方向尺寸）、及玻璃板G的於至少一個角部G1～角部G4處交叉的端面Ga～端面Gd的直角度。即，玻璃板測定裝置1包括真直度測定裝置、尺寸測定裝置、及直角度測定裝置。As shown in FIG1 , the glass plate measuring device 1 of the present embodiment is a device for measuring shape data of a rectangular glass plate G. In the present embodiment, the glass plate measuring device 1 measures the straightness of at least one end face Ga to end face Gd of the glass plate G as shape data, the longitudinal and transverse dimensions (dimensions in the X direction and the dimension in the Y direction) of the glass plate G, and the squareness of the end faces Ga to end faces Gd intersecting at at least one corner G1 to corner G4 of the glass plate G. That is, the glass plate measuring device 1 includes a straightness measuring device, a dimension measuring device, and a squareness measuring device.

（桌台）玻璃板測定裝置1包括具有載置玻璃板G的載置部2x的桌台2作為基本的結構。玻璃板G以端面Ga、端面Gb與X方向實質上平行，端面Gc、端面Gd與Y方向實質上平行的方式，載置於桌台2的載置部2x上。(Table) The glass plate measuring device 1 includes a table 2 having a mounting portion 2x for mounting a glass plate G as a basic structure. The glass plate G is mounted on the mounting portion 2x of the table 2 in such a manner that the end faces Ga and Gb are substantially parallel to the X direction, and the end faces Gc and Gd are substantially parallel to the Y direction.

此處，玻璃板G的厚度例如為0.2 mm～10 mm，玻璃板G的尺寸例如為700 mm×700 mm～3000 mm×3000 mm。玻璃板G藉由下拉（down draw）法（例如溢流下拉（over flow down draw）法）、浮式（float）法等公知的方法來製造。玻璃板G例如用於液晶顯示器等平板顯示器的基板、或觸控面板等的蓋玻璃。Here, the thickness of the glass plate G is, for example, 0.2 mm to 10 mm, and the size of the glass plate G is, for example, 700 mm×700 mm to 3000 mm×3000 mm. The glass plate G is manufactured by a well-known method such as a down draw method (such as an over flow down draw method) or a float method. The glass plate G is used, for example, as a substrate of a flat panel display such as a liquid crystal display, or as a cover glass of a touch panel.

載置部2x亦可由單一或多個平面形成，但於本實施方式中，包括具有與玻璃板G接觸的長尺寸的接觸部的第一凸條部2a及第二凸條部2b。The mounting portion 2x may be formed by a single plane or a plurality of planes, but in the present embodiment, it includes a first ridge portion 2a and a second ridge portion 2b having a long contact portion that contacts the glass plate G.

第一凸條部2a的接觸部沿著玻璃板G的相向的一對端面Ga、端面Gb，即X方向延長，第二凸條部2b的接觸部沿著玻璃板G的相向的一對端面Gc、端面Gd，即Y方向延長。The contact portion of the first ridge 2a extends along a pair of facing end faces Ga and Gb of the glass plate G, that is, in the X direction, and the contact portion of the second ridge 2b extends along a pair of facing end faces Gc and Gd of the glass plate G, that is, in the Y direction.

若如此設定，則第一凸條部2a的接觸部沿著X方向變得細長，因此當使玻璃板G沿著X方向移動時，第一凸條部2a相對於玻璃板G不變成大的阻力。因此，可於利用第一凸條部2a自下方支持玻璃板G的狀態下，使玻璃板G於X方向上順利地移動（滑動）。同樣地，第二凸條部2b的接觸部沿著Y方向變得細長，因此當使玻璃板G沿著Y方向移動時，第二凸條部2b相對於玻璃板G不變成大的阻力。因此，可於利用第二凸條部2b自下方支持玻璃板G的狀態下，使玻璃板G於Y方向上順利地移動（滑動）。因此，可於利用第一凸條部2a及第二凸條部2b支持玻璃板G的狀態下，使玻璃板G於X方向及Y方向的不同的兩個方向上順利地移動而容易地進行定位。另外，與以面支持玻璃板G的整個面的情況相比，第一凸條部2a及第二凸條部2b可減小支持面積，因此即便於支持大尺寸的玻璃板G的情況下，亦可抑制伴隨載置部2x的支持面積的擴大的成本上昇。With such a configuration, the contact portion of the first convex stripe 2a becomes thinner and longer in the X direction, so when the glass sheet G is moved in the X direction, the first convex stripe 2a does not become a large resistance to the glass sheet G. Therefore, the glass sheet G can be smoothly moved (slid) in the X direction while the glass sheet G is supported from below by the first convex stripe 2a. Similarly, the contact portion of the second convex stripe 2b becomes thinner and longer in the Y direction, so when the glass sheet G is moved in the Y direction, the second convex stripe 2b does not become a large resistance to the glass sheet G. Therefore, the glass sheet G can be smoothly moved (slid) in the Y direction while the glass sheet G is supported from below by the second convex stripe 2b. Therefore, the glass sheet G can be smoothly moved in two different directions, the X direction and the Y direction, and can be easily positioned while the glass sheet G is supported by the first ridge portion 2a and the second ridge portion 2b. In addition, the first ridge portion 2a and the second ridge portion 2b can reduce the supporting area compared to the case where the entire surface of the glass sheet G is supported by the surface, so even when supporting a large-sized glass sheet G, the cost increase associated with the increase in the supporting area of the placement portion 2x can be suppressed.

第一凸條部2a於X方向上空開間隔，而於Y方向的多個部位上設置有多個，第二凸條部2b於Y方向上空開間隔，而於X方向的多個部位上設置有多個。即，第一凸條部2a及第二凸條部2b以能夠以穩定的姿勢支持玻璃板G的方式，相互空開間隔而散布於桌台2上。The first ridges 2a are spaced apart in the X direction and provided at multiple locations in the Y direction, and the second ridges 2b are spaced apart in the Y direction and provided at multiple locations in the X direction. That is, the first ridges 2a and the second ridges 2b are spaced apart from each other and are spread on the table 2 so as to support the glass plate G in a stable posture.

第一凸條部2a及第二凸條部2b藉由螺釘等緊固具（未圖示）而可裝卸地固定於桌台2。因此，可個別地更換多個凸條部2a、凸條部2b中的任意的構件。The first convex stripe 2a and the second convex stripe 2b are detachably fixed to the table 2 by fasteners such as screws (not shown). Therefore, any member among the plurality of convex stripe 2a and convex stripe 2b can be replaced individually.

再者，第一凸條部2a及第二凸條部2b的排列形態並無特別限定，例如可為網格狀或鋸齒狀等規則的排列，亦可為不規則的排列。另外，第一凸條部2a的接觸部的長邊方向及第二凸條部2b的接觸部的長邊方向並不限定於X方向或Y方向，只要是互不相同的方向即可。進而，亦可沿著與凸條部2a、凸條部2b不同的方向（例如，與X方向形成的角為45°的方向）進一步設置具有長尺寸的接觸部的其他凸條部。Furthermore, the arrangement form of the first convex stripe 2a and the second convex stripe 2b is not particularly limited, and may be a regular arrangement such as a grid or sawtooth shape, or an irregular arrangement. In addition, the long side direction of the contact portion of the first convex stripe 2a and the long side direction of the contact portion of the second convex stripe 2b are not limited to the X direction or the Y direction, as long as they are different directions. Furthermore, another convex stripe having a long contact portion may be further provided along a direction different from the convex stripe 2a and the convex stripe 2b (for example, a direction forming an angle of 45° with the X direction).

如圖2所示，考慮到第一凸條部2a於桌台2上的姿勢穩定性，第一凸條部2a的短邊方向（Y方向）的剖面形狀為梯形形狀。即，第一凸條部2a的底部2aa側的寬度比上部2ab側的寬度大，以使底部2aa抵接於桌台2的狀態下固定於桌台2。此處，第一凸條部2a的上部2ab（與玻璃板G的接觸部）可為平面，亦可為曲面。或者，凸條部2a的上部2ab亦可使短邊方向的寬度變窄而變成線狀，於此情況下，第一凸條部2a的短邊方向（Y方向）的剖面形狀例如可設為三角形形狀。再者，第一凸條部2a的短邊方向的剖面形狀並無特別限定，可進行各種變更。第一凸條部2a例如可採用如圖3A～圖3D所示的剖面形狀。於圖3A中，第一凸條部2a的前端部（玻璃板G側）為梯形形狀，基端部（桌台2側）為矩形形狀。於圖3B中，第一凸條部2a為前端部構成凸曲面的半圓狀。於圖3C中，第一凸條部2a為具有並列地排列的兩根凸條的U字狀。於圖3D中，第一凸條部2a為刷子狀，即，第一凸條部2a亦可包含刷子。第二凸條部2b的短邊方向（X方向）的剖面形狀並無特別限定，但可採用與第一凸條部2a的短邊方向（Y方向）的剖面形狀相同的形狀。As shown in FIG. 2 , in consideration of the stability of the posture of the first ridge portion 2a on the table 2, the cross-sectional shape of the first ridge portion 2a in the short-side direction (Y direction) is a trapezoidal shape. That is, the width of the bottom 2aa side of the first ridge portion 2a is larger than the width of the upper portion 2ab side, so that the bottom 2aa is fixed to the table 2 in a state of contact with the table 2. Here, the upper portion 2ab of the first ridge portion 2a (the contact portion with the glass plate G) may be a flat surface or a curved surface. Alternatively, the upper portion 2ab of the ridge portion 2a may be narrowed in the short-side direction to be linear, in which case the cross-sectional shape of the first ridge portion 2a in the short-side direction (Y direction) may be, for example, a triangular shape. Furthermore, the cross-sectional shape of the short side direction of the first ridge portion 2a is not particularly limited and can be modified in various ways. The first ridge portion 2a can, for example, adopt a cross-sectional shape as shown in Figures 3A to 3D. In Figure 3A, the front end portion (glass plate G side) of the first ridge portion 2a is a trapezoidal shape, and the base end portion (table 2 side) is a rectangular shape. In Figure 3B, the first ridge portion 2a is a semicircular shape with a convex curved surface at the front end. In Figure 3C, the first ridge portion 2a is a U-shaped shape having two ridges arranged in parallel. In Figure 3D, the first ridge portion 2a is brush-shaped, that is, the first ridge portion 2a can also include a brush. The cross-sectional shape of the second ridge portion 2b in the short side direction (X direction) is not particularly limited, but can adopt the same shape as the cross-sectional shape of the first ridge portion 2a in the short side direction (Y direction).

第一凸條部2a的接觸部及第二凸條部2b的接觸部較佳為例如尼龍等樹脂。若如此設定，則玻璃板G容易於凸條部2a、凸條部2b上滑動。再者，於本實施方式中，第一凸條部2a及第二凸條部2b的整體由樹脂形成。The contact portion of the first ridge 2a and the contact portion of the second ridge 2b are preferably made of a resin such as nylon. If so, the glass plate G can slide easily on the ridge 2a and the ridge 2b. In this embodiment, the first ridge 2a and the second ridge 2b are entirely made of resin.

第一凸條部2a的接觸部的長邊方向的尺寸（X方向尺寸）及第二凸條部2b的接觸部的長邊方向的尺寸（Y方向尺寸）較佳為例如0.2 mm～20 mm。另外，第一凸條部2a的接觸部的短邊方向的尺寸（Y方向尺寸）及第二凸條部2b的接觸部的短邊方向的尺寸（X方向尺寸）較佳為例如5 mm～400 mm。The dimension of the contact portion of the first ridge 2a in the long side direction (dimension in the X direction) and the dimension of the contact portion of the second ridge 2b in the long side direction (dimension in the Y direction) are preferably, for example, 0.2 mm to 20 mm. In addition, the dimension of the contact portion of the first ridge 2a in the short side direction (dimension in the Y direction) and the dimension of the contact portion of the second ridge 2b in the short side direction (dimension in the X direction) are preferably, for example, 5 mm to 400 mm.

如圖1所示，於本實施方式中，載置部2x進而包括多個柱狀的突起部2c。突起部2c利用前端部自下方支持玻璃板G。為了容易進行玻璃板G的定位，突起部2c的前端部亦可包括浮動機構，但於本實施方式中包含球狀輥。突起部2c相互空開間隔而散布於桌台2上。再者，突起部2c的排列形態並無特別限定，例如可為網格狀或鋸齒狀等規則的排列，亦可為不規則的排列。另外，突起部2c的前端部亦可為非轉動體，例如可採用凸曲面或平面等任意的形狀。亦可省略突起部2c。As shown in FIG. 1 , in the present embodiment, the mounting portion 2x further includes a plurality of columnar protrusions 2c. The protrusions 2c support the glass plate G from below using the front end. In order to facilitate the positioning of the glass plate G, the front end of the protrusion 2c may also include a floating mechanism, but in the present embodiment, a spherical roller is included. The protrusions 2c are spaced apart from each other and are scattered on the table 2. Furthermore, the arrangement form of the protrusions 2c is not particularly limited, and may be, for example, a regular arrangement such as a grid or sawtooth shape, or an irregular arrangement. In addition, the front end of the protrusion 2c may also be a non-rotating body, and may be, for example, any shape such as a convex curved surface or a flat surface. The protrusion 2c may also be omitted.

（真直度測定裝置）如圖1所示，玻璃板測定裝置1於桌台2上包括測距計3、保持機構4、直尺5、及仿形機構6作為用於測定玻璃板G的端面Ga～端面Gd的真直度（直線度）的結構。此處，真直度表示直線形狀的自幾何學上正直線的偏差的大小。(Straightness measuring device) As shown in FIG1 , the glass plate measuring device 1 includes a distance meter 3, a holding mechanism 4, a ruler 5, and a profiling mechanism 6 on a table 2 as a structure for measuring the straightness (straightness) of the end faces Ga to Gd of the glass plate G. Here, the straightness refers to the size of the deviation of the straight line shape from a geometrically straight line.

測距計3測定至已載置於桌台2的載置部2x上的玻璃板G的端面Ga為止的距離，即，玻璃板G的端面Ga的自基準位置的位移。此處，於本實施方式中，將基準位置設定為玻璃板G的端面Ga的X方向兩端部的位置。即，以測距計3的測定值於玻璃板G的端面Ga的X方向兩端部顯示零的方式，校正測距計3，並且調整玻璃板G的載置位置。The distance meter 3 measures the distance to the end face Ga of the glass plate G placed on the placing portion 2x of the table 2, that is, the displacement of the end face Ga of the glass plate G from the reference position. Here, in the present embodiment, the reference position is set to the positions of both ends of the end face Ga of the glass plate G in the X direction. That is, the distance meter 3 is calibrated so that the measured value of the distance meter 3 shows zero at both ends of the end face Ga of the glass plate G in the X direction, and the placing position of the glass plate G is adjusted.

測距計3是包括接觸件3a及主軸3b的接觸式的測距計（例如度盤規（dial gauge）），所述接觸件3a與測定對象的端面Ga接觸，所述主軸3b將接觸件3a保持為於Y方向上可進退。於本實施方式中，接觸件3a是圓筒狀的輥，一面與玻璃板G的端面Ga接觸一面轉動（參照後述的圖8）。另外，接觸件3a被測定對象的端面Ga側施力，可仿照測定對象的端面Ga。再者，接觸件3a例如亦可為形成圓筒狀以外的形狀的轉動體（例如球狀輥）、或於玻璃板G的端面Ga上滑動的非轉動體（例如針狀構件或圓筒狀構件等）。The distance meter 3 is a contact type distance meter (e.g., a dial gauge) including a contact member 3a and a main shaft 3b. The contact member 3a contacts the end face Ga of the object to be measured, and the main shaft 3b holds the contact member 3a so that it can move forward and backward in the Y direction. In the present embodiment, the contact member 3a is a cylindrical roller, which rotates while contacting the end face Ga of the glass plate G (refer to FIG. 8 described later). In addition, the contact member 3a is biased by the end face Ga of the object to be measured, and can follow the end face Ga of the object to be measured. Furthermore, the contact member 3a may be, for example, a rotating body (e.g., a spherical roller) formed in a shape other than a cylindrical shape, or a non-rotating body (e.g., a needle-shaped member or a cylindrical member, etc.) that slides on the end face Ga of the glass plate G.

保持機構4將測距計3保持為於Y方向（自玻璃板G的端面Ga分離的方向）及X方向（沿著玻璃板G的端面Ga的方向）上可移動。The holding mechanism 4 holds the distance meter 3 so as to be movable in the Y direction (direction away from the end surface Ga of the glass plate G) and the X direction (direction along the end surface Ga of the glass plate G).

保持機構4包括：第一平台4b，可沿著設置於桌台2上的導軌4a於X方向上移動；以及第二平台4d，可沿著設置於第一平台4b上的導軌4c於Y方向上移動。第一平台4b可藉由手動或自動而於X方向上移動。於第二平台4d上安裝有測距計3。再者，第二平台4d的移動方向與Y方向平行，但亦可相對於Y方向具有角度。The holding mechanism 4 includes: a first platform 4b, which can move in the X direction along a guide rail 4a provided on the table 2; and a second platform 4d, which can move in the Y direction along a guide rail 4c provided on the first platform 4b. The first platform 4b can be moved in the X direction manually or automatically. The distance meter 3 is installed on the second platform 4d. Furthermore, the moving direction of the second platform 4d is parallel to the Y direction, but may also have an angle relative to the Y direction.

保持機構4進而包括尺4e，所述尺4e設置於桌台2上，且表示測距計3的X方向上的位置。於本實施方式中，於尺4e上等間隔地刻有表示藉由測距計3的測定位置的規定的標記。再者，尺4e的配置位置例如可採用直尺5上等任意的位置。亦可省略尺4e。The holding mechanism 4 further includes a ruler 4e, which is placed on the table 2 and indicates the position of the distance meter 3 in the X direction. In the present embodiment, predetermined marks indicating the measured position by the distance meter 3 are engraved at equal intervals on the ruler 4e. The ruler 4e can be arranged at any position, such as on the ruler 5. The ruler 4e can also be omitted.

直尺5沿著X方向設置於桌台2上。事先測定並記錄直尺5的真直度。The ruler 5 is placed on the table 2 along the X direction. The true straightness of the ruler 5 is measured and recorded in advance.

仿形機構6是用於使已安裝於保持機構4的測距計3沿著直尺5的機構。仿形機構6包括按壓構件6a與彈簧6b。The profiling mechanism 6 is a mechanism for making the distance meter 3 mounted on the holding mechanism 4 follow the ruler 5. The profiling mechanism 6 includes a pressing member 6a and a spring 6b.

按壓構件6a的基端部安裝於第二平台4d，前端部與直尺5接觸。The base end of the pressing member 6 a is mounted on the second platform 4 d , and the front end is in contact with the ruler 5 .

彈簧6b以將第二平台4d拉近至直尺5側的方式，橫跨第一平台4b與第二平台4d之間來設置。藉由此種彈簧6b的拉近力，按壓構件6a被直尺5按壓，因此測距計3的X方向位置穩定。再者，彈簧6b亦能夠以按壓第二平台4d來使其靠近直尺5側的方式設置。另外，彈簧6b例如亦可為橡膠等其他彈性體，亦可省略。The spring 6b is provided across the first platform 4b and the second platform 4d so as to pull the second platform 4d closer to the ruler 5. The pressing member 6a is pressed by the ruler 5 by the pulling force of the spring 6b, so that the X-direction position of the distance meter 3 is stabilized. Furthermore, the spring 6b can also be provided so as to press the second platform 4d to bring it closer to the ruler 5. In addition, the spring 6b can also be other elastic bodies such as rubber, or can be omitted.

The ruler 5 includes a concave guide groove 5a for accommodating the roller 6c. That is, the roller 6c rotates on the ruler 5 in a state of being accommodated in the guide groove 5a. In this embodiment, the straightness of the guide groove 5a is measured and recorded in advance as the straightness of the ruler 5. Furthermore, the front end of the pressing member 6a may be, for example, a rotating body (e.g., a spherical roller) formed in a shape other than a cylindrical shape, or a non-rotating body (e.g., a spherical member or a cylindrical member, etc.) that slides on the ruler 5.

（尺寸測定裝置）如圖1所示，玻璃板測定裝置1於桌台2上包括第一銷7、第二銷8、第一尺寸測定計9、及第二尺寸測定計10作為用於測定玻璃板G的X方向尺寸及Y方向尺寸的結構。(Dimension measuring device) As shown in FIG1 , the glass plate measuring device 1 includes a first pin 7, a second pin 8, a first dimension measuring gauge 9, and a second dimension measuring gauge 10 on a table 2 as a structure for measuring the X-direction dimension and the Y-direction dimension of the glass plate G.

The second pin 8 contacts the end surface Ga substantially parallel to the X direction of the glass plate G placed on the placement portion 2x of the table 2. That is, the second pin 8 contacts the end surface Ga intersecting the end surface Gc contacted by the first pin 7 at approximately right angles.

第一尺寸測定計9測定與Y方向實質上平行的端面Gc、端面Gd之間的尺寸，即玻璃板G的X方向尺寸（第一尺寸）。第二尺寸測定計10測定與X方向實質上平行的端面Ga、端面Gb之間的尺寸，即玻璃板G的Y方向尺寸（第二尺寸）。The first dimension measuring gauge 9 measures the dimension between the end faces Gc and Gd substantially parallel to the Y direction, that is, the dimension (first dimension) of the glass plate G in the X direction. The second dimension measuring gauge 10 measures the dimension between the end faces Ga and Gb substantially parallel to the X direction, that is, the dimension (second dimension) of the glass plate G in the Y direction.

In this embodiment, the contact members 9a and 10a are cylindrical non-rotating bodies. Furthermore, the contact members 9a and 10a may be, for example, non-rotating bodies (such as spherical members or needle-shaped members) formed in shapes other than the cylindrical shape, or rotating bodies (such as cylindrical rollers or spherical rollers).

第一尺寸測定計9設置於可調整其X方向位置的第一位置調整機構F上。藉此，可容易地變更第一尺寸測定計9的位置，以可測定尺寸不同的玻璃板G。另外，於測定玻璃板G的尺寸以外的其他形狀資料時等，可使第一尺寸測定計9退避至不變成障礙的位置為止。第一位置調整機構F只要可調整第一尺寸測定計9的X方向位置，則並無特別限定，於本實施方式中，包括：設置於桌台2上的第一導軌Fa、及可沿著第一導軌Fa於X方向上移動的第一滑動件Fb。第一滑動件Fb可藉由手動或自動而於X方向上移動。於第一滑動件Fb上安裝有第一尺寸測定計9。The first dimension measuring gauge 9 is provided on a first position adjusting mechanism F which can adjust its position in the X direction. Thus, the position of the first dimension measuring gauge 9 can be easily changed so that glass plates G of different sizes can be measured. In addition, when measuring other shape data other than the size of the glass plate G, the first dimension measuring gauge 9 can be retreated to a position where it does not become an obstacle. The first position adjusting mechanism F is not particularly limited as long as it can adjust the X direction position of the first dimension measuring gauge 9.

The first slider Fb can be moved in the X direction manually or automatically. The first dimension measuring gauge 9 is mounted on the first slider Fb.

Thus, the position of the second dimension measuring gauge 10 can be easily changed so that glass plates G of different sizes can be measured. In addition, when measuring other shape data other than the size of the glass plate G, the second dimension measuring gauge 10 can be retreated to a position where it does not become an obstacle. The second position adjusting mechanism S is not particularly limited as long as it can adjust the Y direction position of the second dimension measuring gauge 10. In the present embodiment, it includes: a second guide rail Sa provided on the table 2, and a second slider Sb which can move in the Y direction along the second guide rail Sa. The second slider Sb can be moved in the Y direction manually or automatically. The second dimension measuring gauge 10 is mounted on the second slider Sb.

第一銷7及第一尺寸測定計9設有兩組，並且第二銷8及第二尺寸測定計10設有兩組。即，於兩個部位分別測定玻璃板G的X方向尺寸及Y方向尺寸。再者，亦可將X方向尺寸及Y方向尺寸設為兩個部位的平均值。Two sets of the first pin 7 and the first dimension measuring gauge 9 are provided, and two sets of the second pin 8 and the second dimension measuring gauge 10 are provided. That is, the X-direction dimension and the Y-direction dimension of the glass plate G are measured at two locations, respectively. Furthermore, the X-direction dimension and the Y-direction dimension may be set to the average value of the two locations.

成組的第一銷7及第一尺寸測定計9的接觸件9a於X方向上正對。即，成組的第一銷7及第一尺寸測定計9的接觸件9a的Y方向位置實質上相同。同樣地，成組的第二銷8及第二尺寸測定計10的接觸件10a於Y方向正對。即，成組的第二銷8及第二尺寸測定計10的接觸件10a的X方向位置實質上相同。The first pin 7 and the contact piece 9a of the first dimension gauge 9, which form a set, face each other in the X direction. That is, the positions of the first pin 7 and the contact piece 9a of the first dimension gauge 9, which form a set, in the Y direction are substantially the same. Similarly, the second pin 8 and the contact piece 10a of the second dimension gauge 10, which form a set, face each other in the Y direction. That is, the positions of the second pin 8 and the contact piece 10a of the second dimension gauge 10, which form a set, in the X direction are substantially the same.

第一銷7及第二銷8可裝卸地保持於桌台2。於本實施方式中，用於保持銷7、銷8的卡合孔（未圖示）設置於桌台2上。卡合孔較佳為設置於桌台2的多個部位，以於玻璃板G的尺寸經變更時，可調整銷7、銷8的安裝位置。The first pin 7 and the second pin 8 are detachably held on the table 2. In the present embodiment, engaging holes (not shown) for holding the pins 7 and 8 are provided on the table 2. The engaging holes are preferably provided at multiple locations on the table 2 so that the mounting positions of the pins 7 and 8 can be adjusted when the size of the glass plate G is changed.

再者，亦可設為如下結構，即省略成組的第一銷7及第一尺寸測定計9、以及成組的第二銷8及第二尺寸測定計10的任一者，而僅測定第一尺寸及第二尺寸的任一者。就高效地測定玻璃板G的縱向尺寸及橫向尺寸的觀點而言，較佳為同時包括成組的第一銷7及第一尺寸測定計9、以及成組的第二銷8及第二尺寸測定計10。Furthermore, a structure may be adopted in which either the first pin 7 and the first dimension measuring gauge 9, or the second pin 8 and the second dimension measuring gauge 10 are omitted, and only one of the first dimension and the second dimension is measured. From the viewpoint of efficiently measuring the longitudinal dimension and the transverse dimension of the glass sheet G, it is preferable to include both the first pin 7 and the first dimension measuring gauge 9, and the second pin 8 and the second dimension measuring gauge 10.

（直角度測定裝置）如圖1所示，玻璃板測定裝置1於桌台2上包括第一銷11、第二銷12、及測距計13作為用於測定玻璃板G的端面Ga～端面Gd的直角度的結構。再者，圖中的符號14是用於校正測距計13的校正用測距計。(Squareness measuring device) As shown in FIG1 , the glass plate measuring device 1 includes a first pin 11, a second pin 12, and a distance meter 13 on a table 2 as a structure for measuring the squareness of the end faces Ga to Gd of the glass plate G. Furthermore, the symbol 14 in the figure is a calibration distance meter for calibrating the distance meter 13.

第一銷11接觸已載置於桌台2的載置部2x上的玻璃板G的與Y方向實質上平行的端面Gc（第一端面）。第二銷12接觸已載置於桌台2的載置部2x上的玻璃板G的與X方向實質上平行的端面Gb（第二端面）。即，第一銷11及第二銷12分別接觸作為測定直角度的對象的於角部G1處交叉的端面Gc、端面Gb。The first pin 11 contacts the end surface Gc (first end surface) substantially parallel to the Y direction of the glass plate G placed on the placement portion 2x of the table 2. The second pin 12 contacts the end surface Gb (second end surface) substantially parallel to the X direction of the glass plate G placed on the placement portion 2x of the table 2. That is, the first pin 11 and the second pin 12 contact the end surface Gc and the end surface Gb intersecting at the corner G1, which is the object of measuring the right angle, respectively.

第一銷11包含於Y方向上空開間隔來設置的一對銷，第二銷12包含於X方向上僅設置有一個的單一的銷。端面Gc與一對第一銷11接觸，藉此與將一對第一銷11之間連結的直線平行地得到保持。即，以事先設定的規定的傾斜度來保持端面Gc。第二銷12一面維持此種端面Gc的傾斜度，一面與端面Gb接觸。藉此，藉由一對第一銷11、及第二銷12的共計三點來對玻璃板G進行定位。The first pin 11 includes a pair of pins spaced apart in the Y direction, and the second pin 12 includes a single pin provided in the X direction. The end surface Gc is in contact with the pair of first pins 11, thereby being maintained parallel to the straight line connecting the pair of first pins 11. That is, the end surface Gc is maintained at a predetermined inclination set in advance. The second pin 12 is in contact with the end surface Gb while maintaining the inclination of the end surface Gc. In this way, the glass plate G is positioned by a total of three points of the pair of first pins 11 and the second pin 12.

第一銷11及第二銷12可裝卸地保持於桌台2。於本實施方式中，用於保持銷11、銷12的卡合孔（未圖示）設置於桌台2上。卡合孔較佳為設置於桌台2的多個部位，以於玻璃板G的尺寸經變更時，可調整銷11、銷12的安裝位置。The first pin 11 and the second pin 12 are detachably held on the table 2. In the present embodiment, engaging holes (not shown) for holding the pins 11 and 12 are provided on the table 2. The engaging holes are preferably provided at multiple locations on the table 2 so that the mounting positions of the pins 11 and 12 can be adjusted when the size of the glass plate G is changed.

測距計13針對藉由第一銷11及第二銷12進行了定位的玻璃板G，測定於端面Gc與端面Gb為直角時，相對於端面Gb所在的基準位置（參照圖11的由一點鏈線表示的位置）的實際的端面Gb的位置的位移（自基準位置起的Y方向的偏離）。The distance meter 13 measures the displacement (deviation in the Y direction from the reference position) of the actual end face Gb relative to the reference position (the position indicated by a dotted link in FIG. 11 ) where the end face Gc and the end face Gb are at right angles with respect to the glass plate G positioned by the first pin 11 and the second pin 12.

測距計13是包括接觸件13a及主軸13b的接觸式的測距計（例如度盤規），所述接觸件13a與端面Gb接觸，所述主軸13b將接觸件13a保持為於Y方向上可進退。於本實施方式中，接觸件13a是圓筒狀的非轉動體。再者，接觸件13a例如亦可為形成圓筒狀以外的形狀的非轉動體（例如球狀構件或針狀構件）、或轉動體（例如圓筒狀輥或球狀輥）。The distance meter 13 is a contact type distance meter (e.g., a gauge) including a contact member 13a and a main shaft 13b, wherein the contact member 13a contacts the end surface Gb, and the main shaft 13b holds the contact member 13a so that it can move forward and backward in the Y direction. In the present embodiment, the contact member 13a is a cylindrical non-rotating body. Furthermore, the contact member 13a may be, for example, a non-rotating body (e.g., a spherical member or a needle member) or a rotating body (e.g., a cylindrical roller or a spherical roller) formed in a shape other than a cylindrical shape.

測距計13在與第二銷12接觸端面Gb的位置不同的位置上，與端面Gb接觸。於本實施方式中，測距計13在第二銷12接觸端面Gb的位置和端面Gb與端面Gc交叉的位置之間，與端面Gb接觸。The distance meter 13 contacts the end surface Gb at a position different from the position where the second pin 12 contacts the end surface Gb. In this embodiment, the distance meter 13 contacts the end surface Gb between the position where the second pin 12 contacts the end surface Gb and the position where the end surface Gb intersects the end surface Gc.

與測距計13同樣地，校正用測距計14亦為包括接觸件14a及主軸14b的接觸式的測距計（例如度盤規），所述接觸件14a與端面Gb接觸，所述主軸14b將接觸件14a保持為於Y方向上可進退。Similar to the distance meter 13, the calibration distance meter 14 is also a contact-type distance meter (such as a gauge) including a contact member 14a and a spindle 14b. The contact member 14a is in contact with the end surface Gb, and the spindle 14b holds the contact member 14a so that it can move forward and backward in the Y direction.

校正用測距計14在與第二銷12及測距計13接觸端面Gb的位置不同的位置上，與端面Gb接觸。於本實施方式中，校正用測距計14在第二銷12接觸端面Gb的位置與測距計13接觸端面Gb的位置之間，與端面Gb接觸。The calibration distance meter 14 contacts the end surface Gb at a position different from the position where the second pin 12 and the distance meter 13 contact the end surface Gb. In this embodiment, the calibration distance meter 14 contacts the end surface Gb between the position where the second pin 12 contacts the end surface Gb and the position where the distance meter 13 contacts the end surface Gb.

測距計13、測距計14藉由保持機構（例如滑動機構）保持為於Y方向上可移動。藉此，於測定玻璃板G的直角度以外的其他形狀資料時，可使測距計13、測距計14退避至不變成障礙的位置為止。另外，於玻璃板G的尺寸經變更的情況下，可容易地調整測距計13、測距計14的位置。The distance meters 13 and 14 are held by a holding mechanism (e.g., a sliding mechanism) so as to be movable in the Y direction. Thus, when measuring other shape data other than the right angle of the glass plate G, the distance meters 13 and 14 can be retracted to a position where they do not become an obstacle. In addition, when the size of the glass plate G is changed, the position of the distance meters 13 and 14 can be easily adjusted.

（載置夾具）如圖1所示，玻璃板測定裝置1包括自下方支持玻璃板G的載置夾具15作為用於將玻璃板G載置於桌台2的載置部2x上的結構。載置夾具15是包括可使桌台2的凸條部2a、凸條部2b及突起部2c插通的開口部15a的梯子狀的構件。於將玻璃板G自載置夾具15換載於凸條部2a、凸條部2b及突起部2c上後，將載置夾具15載置於桌台2上。再者，凸條部2a、凸條部2b及/或突起部2c只要不與載置夾具15發生干涉，則除開口部15a的內側以外，亦可設置於開口部15a的外側。載置夾具15例如亦可為格子狀的構件等，可採用包括可使凸條部2a、凸條部2b及突起部2c插通的開口部的任意的形狀。(Loading jig) As shown in FIG. 1 , the glass plate measuring device 1 includes a loading jig 15 for supporting the glass plate G from below as a structure for loading the glass plate G on the loading portion 2x of the table 2. The loading jig 15 is a ladder-shaped component including an opening portion 15a through which the ribs 2a, ribs 2b, and protrusions 2c of the table 2 can be inserted. After the glass plate G is transferred from the loading jig 15 to the ribs 2a, ribs 2b, and protrusions 2c, the loading jig 15 is loaded on the table 2. Furthermore, the ribs 2a, ribs 2b, and/or protrusions 2c may be arranged on the outside of the opening 15a in addition to the inside of the opening 15a, as long as they do not interfere with the loading jig 15. The placement jig 15 may be, for example, a lattice-shaped member, and may have any shape including an opening through which the ridges 2a, ridges 2b, and protrusions 2c can be inserted.

繼而，對使用如以上般構成的玻璃板測定裝置1的玻璃板測定方法進行說明。Next, a glass plate measuring method using the glass plate measuring device 1 configured as above will be described.

本實施方式的玻璃板測定方法依次包括：準備步驟，將玻璃板G載置於桌台2的載置部2x上；真直度測定步驟，測定玻璃板G的端面的真直度；尺寸測定步驟，測定玻璃板G的縱橫尺寸；以及直角度測定步驟，測定玻璃板G的端面的直角度。再者，例如亦能夠以尺寸測定步驟、真直度測定步驟、直角度測定步驟的順序進行等調換準備步驟以後的該些步驟的順序。The glass plate measuring method of the present embodiment sequentially comprises: a preparation step of placing a glass plate G on the placing portion 2x of the table 2; a straightness measuring step of measuring the straightness of the end surface of the glass plate G; a dimension measuring step of measuring the longitudinal and transverse dimensions of the glass plate G; and a squareness measuring step of measuring the squareness of the end surface of the glass plate G. Furthermore, the order of the steps after the preparation step may be changed, for example, by performing the dimension measuring step, the straightness measuring step, and the squareness measuring step in this order.

（準備步驟）如圖5所示，於準備步驟中，首先將玻璃板G以已載置於載置夾具15上的狀態搬運至桌台2的上方位置為止（由圖中的一點鏈線表示的狀態）。其次，使載置夾具15自該狀態下降，使桌台2的載置部2x的凸條部2a、凸條部2b及突起部（球狀輥）2c插通載置夾具15的開口部15a。於該過程中，已載置於載置夾具15上的玻璃板G由凸條部2a、凸條部2b及突起部2c向上頂，玻璃板G被自載置夾具15換載於凸條部2a、凸條部2b及突起部2c上。再者，載置夾具15於已載置於桌台2上的狀態下，比凸條部2a、凸條部2b及突起部2c低。因此，可於將玻璃板G自載置夾具15換載於凸條部2a、凸條部2b及突起部2c上後，將載置夾具15載置於桌台2上來收容。(Preparation step) As shown in FIG5, in the preparation step, the glass plate G is first transported to the upper position of the table 2 in a state where it is already placed on the loading jig 15 (the state indicated by the dotted chain in the figure). Next, the loading jig 15 is lowered from this state, and the ribs 2a, ribs 2b and protrusions (ball rollers) 2c of the loading portion 2x of the table 2 are inserted through the opening 15a of the loading jig 15. In this process, the glass plate G already placed on the loading jig 15 is pushed upward by the ribs 2a, ribs 2b and protrusions 2c, and the glass plate G is replaced from the loading jig 15 to the ribs 2a, ribs 2b and protrusions 2c. Furthermore, the loading jig 15 is lower than the ridges 2a, ridges 2b and protrusions 2c when it is placed on the table 2. Therefore, after the glass sheet G is transferred from the loading jig 15 to the ridges 2a, ridges 2b and protrusions 2c, the loading jig 15 can be placed on the table 2 to accommodate it.

（真直度測定步驟）如圖6所示，於真直度測定步驟中，首先進行已由載置部2x支持的玻璃板G的定位。於本實施方式中，以玻璃板G的端面Ga的X方向一端部與X方向另一端部來到規定的基準位置的方式，對玻璃板G進行定位。具體而言，以於用於測定端面Ga的X方向兩端部的第一位置P1及第二位置P2上，由測距計3所測定的自基準位置的位移變成零的方式，對玻璃板G進行定位。於此種玻璃板G的定位作業中，當使測距計3在第一位置P1與第二位置P2之間移動時，為了防止測距計3的接觸件3a的損耗，較佳為設為已使接觸件3a自玻璃板G的端面Ga退避的狀態。其次，於對玻璃板G進行了定位的狀態下，將重物16載置於玻璃板G上，以不使玻璃板G移動。其後，一面利用尺4e確認位置，一面利用保持機構4使測距計3於X方向上每次移動規定距離，而測定玻璃板G的端面Ga的真直度。再者，於真直度測定步驟已結束的階段，自玻璃板G上去除重物16。(Straightness measurement step) As shown in FIG. 6 , in the straightness measurement step, the glass plate G supported by the mounting portion 2x is first positioned. In the present embodiment, the glass plate G is positioned in such a manner that one end portion in the X direction and the other end portion in the X direction of the end surface Ga of the glass plate G arrive at a predetermined reference position. Specifically, the glass plate G is positioned in such a manner that the displacement from the reference position measured by the distance meter 3 becomes zero at the first position P1 and the second position P2 at both ends in the X direction for measuring the end surface Ga. In such a positioning operation of the glass plate G, when the distance meter 3 is moved between the first position P1 and the second position P2, it is preferable to set the contact 3a of the distance meter 3 to a state where the contact 3a has been retracted from the end surface Ga of the glass plate G in order to prevent the wear of the contact 3a. Next, after the glass plate G is positioned, a weight 16 is placed on the glass plate G so as not to move the glass plate G. Thereafter, while the position is confirmed by the ruler 4e, the distance meter 3 is moved a predetermined distance at a time in the X direction by the holding mechanism 4, thereby measuring the straightness of the end face Ga of the glass plate G. Furthermore, at the stage where the straightness measurement step is completed, the weight 16 is removed from the glass plate G.

如圖7所示，於本實施方式中，載置於玻璃板G上的重物16於玻璃板G的端面Ga的附近，沿著端面Ga（即直尺5）來配置。於桌台2，在玻璃板G的端面Ga的附近配置有支持構件17，所述支持構件17沿著端面Ga（即直尺5）延長，隔著玻璃板G而支持重物16。藉此，防止測定真直度的玻璃板G的端面Ga的附近因重物16的負荷而朝下方彎曲。As shown in FIG. 7 , in this embodiment, the weight 16 placed on the glass plate G is arranged near the end surface Ga of the glass plate G and along the end surface Ga (i.e., the ruler 5). On the table 2, a support member 17 is arranged near the end surface Ga of the glass plate G, and the support member 17 extends along the end surface Ga (i.e., the ruler 5) to support the weight 16 across the glass plate G. This prevents the vicinity of the end surface Ga of the glass plate G for measuring straightness from bending downward due to the load of the weight 16.

再者，於真直度測定步驟中，較佳為自桌台2卸下銷7、銷8、銷11、銷12，並且使尺寸測定計9、尺寸測定計10及測距計13、測距計14退避至不變成障礙的位置。作為尺寸測定計9、尺寸測定計10及測距計13、測距計14的退避方法，例如可列舉：使尺寸測定計9、尺寸測定計10及測距計13、測距計14的各自的整體後退至退避位置為止的方法，或者僅使接觸件9a、接觸件10a、接觸件13a、接觸件14a後退至退避位置為止的方法（圖6的狀態）等。Furthermore, in the straightness measuring step, it is preferred that the pins 7, 8, 11, and 12 are removed from the table 2, and the dimension gauges 9, 10, and the distance gauges 13, 14 are retreated to positions where they do not become obstacles. As the retreat method of the dimension gauges 9, 10, and the distance gauges 13, 14, for example, there can be cited a method in which the dimension gauges 9, 10, and the distance gauges 13, 14 are retreated as a whole to the retreat position, or a method in which only the contacts 9a, 10a, 13a, and 14a are retreated to the retreat position (the state of FIG. 6 ).

如圖8所示，測距計3的接觸件3a是圓筒狀的輥，一面與玻璃板G的端面Ga接觸一面轉動。若如此設定，則伴隨接觸件3a的旋轉，接觸件3a之中與玻璃板G的端面Ga接觸的部分依次變化，因此可抑制接觸件3a的磨耗。另外，由於接觸件3a為圓筒狀，因此即便於玻璃板G的端面Ga傾斜的情況下，端面Ga的最突出部的位移亦始終得到測定。因此，由測距計3所測定的真直度的測定誤差變小。再者，接觸件3a的旋轉軸與玻璃板G的厚度方向（Z方向）實質上平行。As shown in FIG8 , the contact member 3a of the distance meter 3 is a cylindrical roller that rotates while contacting the end face Ga of the glass plate G. If so, as the contact member 3a rotates, the portion of the contact member 3a that contacts the end face Ga of the glass plate G changes sequentially, thereby suppressing the wear of the contact member 3a. In addition, since the contact member 3a is cylindrical, even if the end face Ga of the glass plate G is tilted, the displacement of the most protruding part of the end face Ga is always measured. Therefore, the measurement error of the straightness measured by the distance meter 3 is reduced. Furthermore, the rotation axis of the contact member 3a is substantially parallel to the thickness direction (Z direction) of the glass plate G.

如圖6所示，將直尺5作為基準來決定測距計3的Y方向的位置，因此由測距計3所測定的玻璃板G的端面Ga的位移（真直度）受到直尺5的真直度的影響。因此，將經測定的玻璃板G的端面Ga的真直度S1與已知的直尺5的真直度S2的差（S1－S2）作為最終的玻璃板G的端面Ga的真直度來記錄。As shown in Fig. 6, the Y-direction position of the distance meter 3 is determined with the ruler 5 as a reference, so the displacement (straightness) of the end surface Ga of the glass plate G measured by the distance meter 3 is affected by the straightness of the ruler 5. Therefore, the difference (S1-S2) between the measured straightness S1 of the end surface Ga of the glass plate G and the known straightness S2 of the ruler 5 is recorded as the final straightness of the end surface Ga of the glass plate G.

再者，較佳為於測定玻璃板G的端面Ga的真直度之後，於位置P1、位置P2上利用測距計3再次測定玻璃板G的端面Ga，確認有無玻璃板G的位置偏離。即，若於位置P1、位置P2兩者上由測距計3所測定的自基準位置的位移為零，則可確認玻璃板G於測定前後無位置偏離。Furthermore, it is preferred that after measuring the straightness of the end surface Ga of the glass plate G, the end surface Ga of the glass plate G is measured again at the position P1 and the position P2 using the distance meter 3 to confirm whether there is positional deviation of the glass plate G. That is, if the displacement from the reference position measured by the distance meter 3 at both the position P1 and the position P2 is zero, it can be confirmed that the glass plate G has no positional deviation before and after the measurement.

以上例示了測定玻璃板G的端面Ga的真直度的情況，但較佳為測定玻璃板G的四個端面Ga～端面Gd的各自的真直度。於此情況下，於測定玻璃板G的端面Ga的真直度後，利用載置夾具15或其他元件來變更相對於桌台2的玻璃板G的方向，並以相同的程序測定剩餘的端面Gb～端面Gd的真直度。若測定玻璃板G的四個端面Ga～端面Gd的各自的真直度，則例如於玻璃板G的製造步驟所包含的端面加工步驟中，可根據玻璃板G的各端面Ga～端面Gd的真直度來準確地調整加工工具的位置。因此，容易以固定研磨量對玻璃板G的各端面Ga～端面Gd進行加工。再者，此種根據真直度來調整加工工具的位置的方法亦可應用於實施定壓研磨的情況。The above example shows the case where the straightness of the end face Ga of the glass plate G is measured, but it is preferable to measure the straightness of each of the four end faces Ga to Gd of the glass plate G. In this case, after the straightness of the end face Ga of the glass plate G is measured, the direction of the glass plate G relative to the table 2 is changed by using the mounting fixture 15 or other components, and the straightness of the remaining end faces Gb to Gd is measured by the same procedure. If the straightness of each of the four end faces Ga to Gd of the glass plate G is measured, for example, in the end face processing step included in the manufacturing step of the glass plate G, the position of the processing tool can be accurately adjusted according to the straightness of each end face Ga to Gd of the glass plate G. Therefore, it is easy to process each end face Ga to Gd of the glass plate G with a fixed grinding amount. Furthermore, this method of adjusting the position of the processing tool according to the straightness can also be applied to the case of constant pressure grinding.

（尺寸測定步驟）如圖9所示，於尺寸測定步驟中，首先使第一銷7及第二銷8接觸玻璃板G的端面Ga、端面Gc，對已由載置部2x支持的玻璃板G進行定位。於該狀態下，使尺寸測定計9、尺寸測定計10的接觸件9a、接觸件10a接觸玻璃板G的端面Gb、端面Gd，測定玻璃板G的X方向尺寸及Y方向尺寸。尺寸測定計9、尺寸測定計10的接觸件9a、接觸件10a為圓筒狀，因此與測距計3的接觸件3a同樣地，測定玻璃板G的端面Gb、端面Gd的最突出部的位置。(Dimension measurement step) As shown in FIG9 , in the dimension measurement step, first, the first pin 7 and the second pin 8 are brought into contact with the end surface Ga and the end surface Gc of the glass plate G to position the glass plate G supported by the mounting portion 2x. In this state, the contact pieces 9a and 10a of the dimension measuring gauge 9 and the dimension measuring gauge 10 are brought into contact with the end surface Gb and the end surface Gd of the glass plate G to measure the X-direction dimension and the Y-direction dimension of the glass plate G. The contact pieces 9a and 10a of the dimension measuring gauge 9 and the dimension measuring gauge 10 are cylindrical, and thus, like the contact piece 3a of the distance meter 3, the positions of the most protruding parts of the end surfaces Gb and the end surfaces Gd of the glass plate G are measured.

玻璃板G的X方向尺寸及Y方向尺寸可同時測定，亦可分開測定。於分開測定的情況下，例如使第一銷7接觸玻璃板G的端面Gc，藉由第一尺寸測定計9來測定玻璃板G的X方向的尺寸後，解除第一銷7及第一尺寸測定計9與玻璃板G的接觸，並且使第二銷8接觸玻璃板G的端面Ga，藉由第二尺寸測定計10來測定玻璃板G的Y方向的尺寸。The X-direction dimension and the Y-direction dimension of the glass plate G may be measured simultaneously or separately. In the case of separate measurement, for example, the first pin 7 is brought into contact with the end surface Gc of the glass plate G, and the X-direction dimension of the glass plate G is measured by the first dimension measuring gauge 9. Then, the first pin 7 and the first dimension measuring gauge 9 are released from contact with the glass plate G, and the second pin 8 is brought into contact with the end surface Ga of the glass plate G, and the Y-direction dimension of the glass plate G is measured by the second dimension measuring gauge 10.

再者，於本實施方式中，於兩個部位分別測定X方向尺寸及Y方向尺寸，但銷和與其正對的尺寸測定計的組數可適宜變更。即，可僅於一個部位分別測定X方向尺寸及Y方向尺寸，亦可於三個部位以上分別測定X方向尺寸及Y方向尺寸。Furthermore, in the present embodiment, the X-direction dimension and the Y-direction dimension are measured at two locations, but the number of sets of pins and dimension measuring gauges facing the pins can be changed as appropriate. That is, the X-direction dimension and the Y-direction dimension can be measured at only one location, or at three or more locations.

於尺寸測定步驟中，較佳為使測距計3、測距計13、測距計14退避至不變成障礙的位置。作為測距計3、測距計13、測距計14的退避方法，例如可列舉：使測距計3、測距計13、測距計14的各自的整體後退至退避位置為止的方法，或者僅使接觸件3a、接觸件13a、接觸件14a後退至退避位置為止的方法（圖9的狀態）等。In the dimension measurement step, it is preferable to make the rangefinder 3, the rangefinder 13, and the rangefinder 14 retreat to a position where they do not become an obstacle. As the retreat method of the rangefinder 3, the rangefinder 13, and the rangefinder 14, for example, there can be listed: a method of retreating the rangefinder 3, the rangefinder 13, and the rangefinder 14 as a whole to the retreat position, or a method of retreating only the contact 3a, the contact 13a, and the contact 14a to the retreat position (the state of FIG. 9), etc.

（直角度測定步驟）如圖10所示，於直角度測定步驟中，首先使第一銷11及第二銷12接觸玻璃板G的端面Gb、端面Gc，對已由載置部2x支持的玻璃板G進行定位。於該狀態下，使測距計13的接觸件13a接觸玻璃板G的端面Gb，測定端面Gb的自基準位置的位移（Y方向的位移）。測距計13的接觸件13a為圓筒狀，因此與測距計3的接觸件3a同樣地，測定玻璃板G的端面Ga的最突出部的位置。(Squarishness measurement step) As shown in FIG. 10, in the squareness measurement step, the first pin 11 and the second pin 12 are first brought into contact with the end surface Gb and the end surface Gc of the glass plate G to position the glass plate G supported by the mounting portion 2x. In this state, the contact piece 13a of the distance meter 13 is brought into contact with the end surface Gb of the glass plate G to measure the displacement (displacement in the Y direction) of the end surface Gb from the reference position. The contact piece 13a of the distance meter 13 is cylindrical, so the position of the most protruding part of the end surface Ga of the glass plate G is measured in the same manner as the contact piece 3a of the distance meter 3.

已由測距計13測定的位移被換算成相對於端面Gc的垂直面的端面Gb的傾斜度，該傾斜度表示直角度。如圖11所示，相對於端面Gc的垂直面的端面Gb的傾斜度（直角度）例如由自端面Gc與端面Gb交叉的位置至端面Gd與端面Gb交叉的位置為止的Y方向的位移M（＝d1×d3/d2），或端面Gc的垂直面與端面Gb形成的角θ（＝tan^-1 （d1/d2））表示。此處，d1是已由測距計13測定的Y方向的位移，d2是已知的測距計13與第二銷12之間的X方向距離，d3是已知的玻璃板G的X方向尺寸（設計值）。例如，可利用運算裝置根據已由測距計13測定的位移而自動運算相對於端面Gc的垂直面的端面Gb的傾斜度，亦可事先製作將已由測距計13測定的位移換算成傾斜度的換算表，並自該換算表讀取相對於端面Gc的垂直面的端面Gb的傾斜度。The displacement measured by the distance meter 13 is converted into the inclination of the end face Gb relative to the vertical plane of the end face Gc, and the inclination represents the right angle. As shown in FIG11, the inclination (right angle) of the end face Gb relative to the vertical plane of the end face Gc is represented by, for example, the displacement M (= d1 × d3 / d2) in the Y direction from the position where the end face Gc and the end face Gb intersect to the position where the end face Gd and the end face Gb intersect, or the angle θ (= tan ^-1 (d1 / d2)) formed by the vertical plane of the end face Gc and the end face Gb. Here, d1 is the displacement in the Y direction measured by the distance meter 13, d2 is the known distance in the X direction between the distance meter 13 and the second pin 12, and d3 is the known X-direction dimension (design value) of the glass plate G. For example, a computing device may be used to automatically calculate the inclination of the end face Gb relative to the vertical plane of the end face Gc based on the displacement measured by the rangefinder 13, or a conversion table may be prepared in advance to convert the displacement measured by the rangefinder 13 into an inclination, and the inclination of the end face Gb relative to the vertical plane of the end face Gc may be read from the conversion table.

如此測定直角度，並對所製造的玻璃板G的直角度進行管理，藉此例如可防止於加工·清洗·檢查等各種步驟（包含交貨地的步驟）中產生玻璃板G的對準（定位）的偏離。By measuring the squareness in this way and managing the squareness of the manufactured glass sheet G, it is possible to prevent the alignment (positioning) of the glass sheet G from being deviated during various steps such as processing, cleaning, and inspection (including steps at the delivery destination).

以上例示了測定玻璃板G的於角部G1處交叉的端面的直角度的情況，但亦可對玻璃板G的於四個角部G1～角部G4的各角部處交叉的端面的直角度全部進行測定。於此情況下，於測定玻璃板G的於角部G1處交叉的端面的直角度後，利用載置夾具15或其他元件來變更相對於桌台2的玻璃板G的方向，並以相同的程序測定於剩餘的角部G2～角部G4處交叉的端面的直角度。The above example shows the case where the right angle of the end faces of the glass plate G intersecting at the corner G1 is measured, but the right angles of the end faces intersecting at each of the four corners G1 to G4 of the glass plate G can also be measured. In this case, after the right angle of the end faces of the glass plate G intersecting at the corner G1 is measured, the direction of the glass plate G relative to the table 2 is changed by using the mounting fixture 15 or other elements, and the right angles of the end faces intersecting at the remaining corners G2 to G4 are measured by the same procedure.

再者，於直角度測定步驟中，較佳為自桌台2卸下銷7、銷8，並且使測距計3、測距計14及尺寸測定計9、尺寸測定計10退避至不變成障礙的位置。作為測距計3、測距計14及尺寸測定計9、尺寸測定計10的退避方法，例如可列舉：使測距計3、測距計14及尺寸測定計9、尺寸測定計10的各自的整體後退至退避位置為止的方法，或者僅使接觸件3a、接觸件9a、接觸件10a、接觸件14a後退至退避位置為止的方法（圖10的狀態）等。Furthermore, in the step of measuring the right angle, it is preferred that the pins 7 and 8 are removed from the table 2, and the distance meter 3, the distance meter 14, and the dimension measuring meter 9, and the dimension measuring meter 10 are retreated to a position where they do not become an obstacle. As a method of retreating the distance meter 3, the distance meter 14, and the dimension measuring meter 9, and the dimension measuring meter 10, for example, there can be cited a method of retreating the distance meter 3, the distance meter 14, and the dimension measuring meter 9, and the dimension measuring meter 10 as a whole to the retreat position, or a method of retreating only the contact 3a, the contact 9a, the contact 10a, and the contact 14a to the retreat position (the state of FIG. 10 ).

（校正步驟）本實施方式的玻璃板測定方法於準備步驟之前，進而包括：第一校正步驟，對尺寸測定步驟中所使用的尺寸測定計9、尺寸測定計10進行校正；以及第二校正步驟，對直角度測定中所使用的測距計13進行校正。該些校正步驟可於每次測定玻璃板G時均實施，亦可於進行規定次數或規定時間的玻璃板G的測定後實施。另外，亦可於測定對象的玻璃板G的尺寸變化的情況下實施。當然，可僅實施第一校正步驟，亦可僅實施第二校正步驟。(Calibration step) The glass plate measuring method of this embodiment further includes, before the preparation step: a first calibration step of calibrating the size measuring gauge 9 and the size measuring gauge 10 used in the size measuring step; and a second calibration step of calibrating the distance meter 13 used in the squareness measurement. These calibration steps can be performed every time the glass plate G is measured, or after the glass plate G is measured a specified number of times or for a specified time. In addition, they can also be performed when the size of the glass plate G to be measured changes. Of course, only the first calibration step can be performed, or only the second calibration step can be performed.

如圖12及圖13所示，於第一校正步驟中，使用棒狀的第一校正夾具18對第一尺寸測定計9進行校正，使用棒狀的第二校正夾具19對第二尺寸測定計10進行校正。圖12利用實線表示使用第一校正夾具18對第一尺寸測定計9進行校正的狀態，利用一點鏈線表示使用第二校正夾具19對第二尺寸測定計10進行校正的狀態。再者，第一尺寸測定計9的校正與第二尺寸測定計10的校正分開實施。As shown in FIG. 12 and FIG. 13, in the first calibration step, the first dimension measuring gauge 9 is calibrated using the first calibration fixture 18 in a rod shape, and the second dimension measuring gauge 10 is calibrated using the second calibration fixture 19 in a rod shape. FIG. 12 uses a solid line to indicate the state of calibrating the first dimension measuring gauge 9 using the first calibration fixture 18, and uses a dot chain line to indicate the state of calibrating the second dimension measuring gauge 10 using the second calibration fixture 19. Furthermore, the calibration of the first dimension measuring gauge 9 and the calibration of the second dimension measuring gauge 10 are performed separately.

第一校正夾具18及第二校正夾具19的長度已知。於本實施方式中，將第一校正夾具18的長度設定為玻璃板G的X方向尺寸的基準尺寸（設計尺寸），將第二校正夾具19的長度設定為玻璃板G的Y方向尺寸的基準尺寸（設計尺寸）。再者，較佳為亦定期（例如每年一次左右）地實施校正夾具18、校正夾具19自身的校正。The lengths of the first calibration jig 18 and the second calibration jig 19 are known. In the present embodiment, the length of the first calibration jig 18 is set as the reference size (design size) of the X-direction dimension of the glass plate G, and the length of the second calibration jig 19 is set as the reference size (design size) of the Y-direction dimension of the glass plate G. Furthermore, it is preferable to calibrate the calibration jigs 18 and 19 themselves regularly (for example, once a year or so).

於第一尺寸測定計9的校正時，使第一校正夾具18的一端接觸第一銷7，並且使第一校正夾具18的另一端接觸第一尺寸測定計9的接觸件9a。於第二尺寸測定計10的校正時，使第二校正夾具19的一端接觸第二銷8，並且使第二校正夾具19的另一端接觸第二尺寸測定計10的接觸件10a。When calibrating the first dimension gauge 9, one end of the first calibration jig 18 is brought into contact with the first pin 7, and the other end of the first calibration jig 18 is brought into contact with the contact piece 9a of the first dimension gauge 9. When calibrating the second dimension gauge 10, one end of the second calibration jig 19 is brought into contact with the second pin 8, and the other end of the second calibration jig 19 is brought into contact with the contact piece 10a of the second dimension gauge 10.

第一尺寸測定計9的基準位置（例如零點）被校正成接觸件9a與第一校正夾具18接觸的位置，第二尺寸測定計10的基準位置（例如零點）被校正成接觸件10a與第二校正夾具19接觸的位置。The reference position (e.g., zero point) of the first dimension measuring gauge 9 is calibrated to a position where the contact piece 9a contacts the first calibration fixture 18, and the reference position (e.g., zero point) of the second dimension measuring gauge 10 is calibrated to a position where the contact piece 10a contacts the second calibration fixture 19.

於本實施方式中，第一尺寸測定計9測定玻璃板G的端面Gd的自基準位置的位移，第二尺寸測定計10測定玻璃板G的端面Gb的自基準位置的位移。即，將各方向的基準尺寸與經測定的位移（比基準尺寸短的情況為負的位移，比基準尺寸長的情況為正的位移）的和作為玻璃板G的X方向尺寸及Y方向尺寸來記錄。因此，若如所述般校正尺寸測定計9、尺寸測定計10的基準位置，則X方向尺寸及Y方向尺寸的測定精度提昇。In the present embodiment, the first dimension measuring gauge 9 measures the displacement of the end surface Gd of the glass plate G from the reference position, and the second dimension measuring gauge 10 measures the displacement of the end surface Gb of the glass plate G from the reference position. That is, the sum of the reference dimensions in each direction and the measured displacement (negative displacement when shorter than the reference dimension, positive displacement when longer than the reference dimension) is recorded as the X-direction dimension and the Y-direction dimension of the glass plate G. Therefore, if the reference positions of the dimension measuring gauges 9 and 10 are calibrated as described above, the measurement accuracy of the X-direction dimension and the Y-direction dimension is improved.

第一校正夾具18包括小徑部18a、及直徑比小徑部18a大的大徑部18b。同樣地，第二校正夾具19包括小徑部19a、及直徑比小徑部19a大的大徑部19b。小徑部18a、小徑部19a及大徑部18b、大徑部19b的材質並無特別限定，但於本實施方式中，小徑部18a、小徑部19a由金屬形成，大徑部18b、大徑部19b由橡膠形成。The first calibration fixture 18 includes a small diameter portion 18a and a large diameter portion 18b having a larger diameter than the small diameter portion 18a. Similarly, the second calibration fixture 19 includes a small diameter portion 19a and a large diameter portion 19b having a larger diameter than the small diameter portion 19a. The materials of the small diameter portions 18a, 19a and the large diameter portions 18b, 19b are not particularly limited, but in this embodiment, the small diameter portions 18a, 19a are formed of metal, and the large diameter portions 18b, 19b are formed of rubber.

於桌台2上設置有支持第一校正夾具18的大徑部18b的第一支持部20、及支持第二校正夾具19的大徑部19b的第二支持部21。支持部20、支持部21的上表面為了支持圓筒狀的大徑部18b、大徑部19b，而形成有半圓筒狀的凹槽。利用支持部20、支持部21來支持校正夾具18、校正夾具19的大徑部18b、大徑部19b，藉此自動地調整校正夾具18、校正夾具19的高度。因此，尺寸測定計9、尺寸測定計10的校正作業變得容易。The table 2 is provided with a first support portion 20 for supporting the large diameter portion 18b of the first calibration jig 18 and a second support portion 21 for supporting the large diameter portion 19b of the second calibration jig 19. The upper surfaces of the support portions 20 and 21 are formed with semi-cylindrical grooves to support the cylindrical large diameter portions 18b and 19b. The support portions 20 and 21 are used to support the large diameter portions 18b and 19b of the calibration jig 18 and 19, thereby automatically adjusting the height of the calibration jig 18 and 19. Therefore, the calibration operation of the dimension measuring gauge 9 and the dimension measuring gauge 10 becomes easy.

第一支持部20及第二支持部21比桌台2的載置部2x，即凸條部2a、凸條部2b及突起部2c低。藉此，如圖14所示，當不實施校正作業時，該些支持部20、支持部21不與已載置於載置部2x上的玻璃板G接觸。The first support portion 20 and the second support portion 21 are lower than the mounting portion 2x of the table 2, that is, the ridge portion 2a, the ridge portion 2b and the protrusion 2c. Thus, as shown in FIG. 14 , when the calibration operation is not performed, the support portions 20 and the support portions 21 do not contact the glass plate G mounted on the mounting portion 2x.

如圖15及圖16所示，於第二校正步驟中，使用校正用夾具（例如角尺）22與校正用測距計14對測距計13進行校正，所述校正用夾具（例如角尺）22具有可與第一銷11及第二銷12接觸、且相互形成直角的第一保證面22a及第二保證面22b，所述校正用測距計14於已使第一保證面22a接觸第一銷11的狀態下，測定第二保證面22b的位置自基準位置的位移。再者，較佳為亦定期（例如每年一次左右）地實施校正用夾具22自身的校正。As shown in Fig. 15 and Fig. 16, in the second calibration step, the distance meter 13 is calibrated using a calibration fixture (e.g., a square) 22 having a first securing surface 22a and a second securing surface 22b that can contact the first pin 11 and the second pin 12 and form a right angle with each other, and the calibration distance meter 14 measures the displacement of the position of the second securing surface 22b from the reference position in a state where the first securing surface 22a is in contact with the first pin 11. It is also preferable to calibrate the calibration fixture 22 itself regularly (e.g., once a year or so).

於測距計13的校正時準確地設置校正用夾具22非常困難，其作業需要熟練。因此，於已使校正用夾具22的第一保證面22a接觸一對第一銷11的狀態下，一面確認與校正用夾具22的第二保證面22b相關的測距計13及校正用測距計14的數值一致，一面使校正用夾具22朝第二銷12側（Y方向）移動。若如此設定，則可於將校正用夾具22維持成正確的姿勢的狀態下，使校正用夾具22的第二保證面22b接觸第二銷12。其結果，可簡單且準確地進行校正用夾具22的設置。而且，若利用測距計13測定如此設置的校正用夾具22的第二保證面22b的位置並對基準位置（零點）進行修正，則可準確地校正測距計13。It is very difficult to accurately set the calibration jig 22 when calibrating the distance meter 13, and the operation requires proficiency. Therefore, in a state where the first securing surface 22a of the calibration jig 22 is in contact with a pair of first pins 11, the calibration jig 22 is moved toward the second pin 12 side (Y direction) while confirming that the values of the distance meter 13 and the calibration distance meter 14 related to the second securing surface 22b of the calibration jig 22 are consistent. If set in this way, the second securing surface 22b of the calibration jig 22 can be brought into contact with the second pin 12 while the calibration jig 22 is maintained in a correct posture. As a result, the calibration jig 22 can be easily and accurately set. Then, if the position of the second securing surface 22 b of the calibration jig 22 thus provided is measured by the distance meter 13 and the reference position (zero point) is corrected, the distance meter 13 can be accurately calibrated.

再者，較佳為於第二校正步驟結束後，使校正用測距計14退避至不與玻璃板G的端面Gb接觸的位置為止。若如此設定，則當利用測距計13測定玻璃板G的端面Gb時，校正用測距計14不會變成測距計13進行測定的障礙。此時，除利用所述方法使校正用測距計14退避以外，亦可自桌台2卸下校正用測距計14而使其退避。Furthermore, it is preferable that after the second calibration step is completed, the calibration distance meter 14 is retracted to a position where it does not contact the end surface Gb of the glass plate G. If so, when the end surface Gb of the glass plate G is measured by the distance meter 13, the calibration distance meter 14 does not become an obstacle to the measurement by the distance meter 13. At this time, in addition to retracting the calibration distance meter 14 by the above method, the calibration distance meter 14 can also be removed from the table 2 to be retracted.

此處，本實施方式的玻璃板測定方法例如於玻璃板製造步驟中實施。玻璃板製造步驟包括：成形步驟，使玻璃板成形；切斷步驟，將已成形的玻璃板切斷成規定尺寸；以及端面加工步驟，對玻璃板的經切斷的端面實施倒角等精加工。玻璃板測定方法例如於切斷步驟及/或端面加工步驟後實施。於此情況下，自製造途中的玻璃板中抽取一塊或多塊玻璃板作為玻璃板測定方法的測定試樣。再者，經抽取的玻璃板（測定試樣）於測定形狀資料後被廢棄，例如作為玻璃屑（cullet）而再次利用。Here, the glass plate measuring method of the present embodiment is implemented, for example, in a glass plate manufacturing step. The glass plate manufacturing step includes: a forming step of forming a glass plate; a cutting step of cutting the formed glass plate into a specified size; and an end surface processing step of performing finishing processes such as chamfering on the cut end surface of the glass plate. The glass plate measuring method is implemented, for example, after the cutting step and/or the end surface processing step. In this case, one or more glass plates are extracted from the glass plates in the process of being manufactured as measurement samples for the glass plate measuring method. Furthermore, the extracted glass plates (measurement samples) are discarded after the shape data is measured, for example, and are reused as glass chips (cullets).

如以上般，根據本實施方式的玻璃板測定裝置1，可不使用高度的圖像處理等，而簡單且確實地測定玻璃板G的包含端面的真直度、縱橫尺寸、端面的直角度的形狀資料。另外，玻璃板G的該些形狀資料可於載置部2x上全部測定，因此可謀求省空間化。進而，玻璃板G由凸條部2a、凸條部2b及突起部2c支持，因此即便於玻璃板G為大尺寸的情況下，亦可容易且低成本地實現其定位。As described above, according to the glass plate measuring device 1 of the present embodiment, the shape data including the straightness of the end surface, the longitudinal and transverse dimensions, and the right angle of the end surface of the glass plate G can be simply and accurately measured without using advanced image processing, etc. In addition, since all of these shape data of the glass plate G can be measured on the mounting portion 2x, space saving can be achieved. Furthermore, the glass plate G is supported by the ribs 2a, ribs 2b, and protrusions 2c, so even if the glass plate G is large in size, its positioning can be easily and inexpensively achieved.

再者，本發明不受所述實施方式任何限定，進而可於不脫離本發明的主旨的範圍內以各種形態來實施。Furthermore, the present invention is not limited to the above-described embodiments and can be implemented in various forms without departing from the gist of the present invention.

於所述實施方式中，對在端面的多個部位斷續地測定玻璃板G的端面的真直度的情況進行了說明，但亦可於端面上連續地測定。同樣地，對在一個端面的兩個部位測定玻璃板G的尺寸的情況進行了說明，但亦可於端面的一個部位測定玻璃板G的尺寸，亦可於三部位以上或沿著端面連續地測定。In the above-described embodiment, the straightness of the end surface of the glass plate G is measured intermittently at a plurality of locations on the end surface, but it may be measured continuously on the end surface. Similarly, the size of the glass plate G is measured at two locations on one end surface, but it may be measured at one location on the end surface, or it may be measured continuously at three or more locations or along the end surface.
