Description
本發明係關於一種玻璃板收納體及化學強化玻璃之製造方法。 The present invention relates to a glass plate storage body and a method of producing chemically strengthened glass.
作為強化玻璃板之方法之一，例如有將玻璃板投入至將硝酸鉀等熔融而成之熔鹽中進行化學強化之方法(例如參照專利文獻1)。該方法係將收納有複數個玻璃板之玻璃板收納體投入到加熱至400~450℃之熔鹽槽中，浸漬特定時間並進行離子交換，藉此於玻璃板之表面形成壓縮應力層。 For example, a method of chemically strengthening a glass plate into a molten salt obtained by melting potassium nitrate or the like (for example, see Patent Document 1). In this method, a glass plate container in which a plurality of glass plates are housed is placed in a molten salt bath heated to 400 to 450 ° C, and immersed for a specific time to perform ion exchange, whereby a compressive stress layer is formed on the surface of the glass plate.
為了提高1次投入作業之處理效率，較理想為將玻璃板大面積化並且於玻璃板收納體中增加玻璃板之收納片數。又，例如於使用玻璃板作為可攜式電子機器顯示器用外罩之情形時，為了輕量化而有變得更薄之傾向。作為玻璃板收納體，有如下構成者，即，為了將各玻璃板呈垂直地立起之狀態支持，且縮小各玻璃板之間隔並增加玻璃板之收納片數，而將支持構件設置於左右兩側之側壁。 In order to increase the processing efficiency of one input operation, it is preferable to increase the area of the glass sheet and increase the number of sheets of the glass sheet in the glass sheet storage body. Further, for example, when a glass plate is used as a cover for a portable electronic device display, it tends to be thinner in order to reduce the weight. The glass plate storage body is configured to support the glass plates in a vertical state, and to reduce the interval between the glass plates and increase the number of storage sheets of the glass plates, and to provide the support members to the left and right sides. Side walls on both sides.
圖1係表示設置於先前之玻璃板收納體之支持構件之一例之俯視圖。如圖1所示，玻璃板收納體10在橫架於側方之兩側之樑12、14設置有支持玻璃板之支持構件20A、20B。各支持構件20A、20B由於要被投入到加熱至高溫之熔鹽中，故而由金屬形成，且以特定之間距交替地形成有梯形狀之凸部30、及梯形狀之凹部40。複數個玻璃板50係藉由使兩側側方之周緣部52、54***至凹部40而呈大致垂直狀態被支持。又，各玻璃板50係由各凸部30之間之寬度最窄之傾斜部分32之根 部附近(凹部40之內部)支持周緣部52、54。 Fig. 1 is a plan view showing an example of a supporting member provided in a conventional glass plate housing. As shown in Fig. 1, the glass sheet storage body 10 is provided with support members 20A and 20B for supporting glass sheets on the beams 12 and 14 which are laterally arranged on both sides. Each of the support members 20A and 20B is formed of a metal because it is to be heated to a molten salt heated to a high temperature, and a ladder-shaped convex portion 30 and a trapezoidal concave portion 40 are alternately formed at a predetermined interval. The plurality of glass sheets 50 are supported in a substantially vertical state by inserting the peripheral edges 52, 54 on both sides into the recess 40. Further, each of the glass sheets 50 is the root of the inclined portion 32 having the narrowest width between the respective convex portions 30. The peripheral portion 52, 54 is supported in the vicinity of the portion (inside of the recess 40).
然而，於使用先前之玻璃板收納體對玻璃板進行化學強化之情形時，產生了如下問題。 However, when the glass plate is chemically strengthened using the previous glass plate storage body, the following problems occur.
於玻璃板50之周緣部52、54之端面(邊緣)產生導致破裂(缺損)之損傷(參照圖1中之A部)。 Damage to the end surface (edge) of the peripheral edge portions 52, 54 of the glass sheet 50 causes damage (defect) (refer to portion A in Fig. 1).
於玻璃板50之表面(較周緣部52、54更靠內側之正面、背面)，收納體之一部分與之接觸而產生損傷或擦痕(參照圖1中之B部)。 On the surface of the glass sheet 50 (the front side and the back side of the inner side of the peripheral edge portions 52 and 54), a part of the storage body comes into contact with it to cause damage or scratches (see the portion B in Fig. 1).
因將玻璃板50投入至熔鹽槽中時、及將玻璃板50自熔鹽槽提拉時之振動或搖晃而導致垂直狀態之玻璃板50之周緣部52、54自支持構件20A、20B脫離，或者因利用車輛搬運玻璃板收納體10時、或利用升降裝置使玻璃板收納體10升降時之振動而導致玻璃板50之周緣部52、54自支持構件20A、20B脫離，從而導致玻璃板破損或損傷(參照圖1中之C部)。 The peripheral portions 52, 54 of the glass plate 50 in the vertical state are separated from the support members 20A, 20B by the vibration or shaking when the glass plate 50 is put into the molten salt bath and when the glass plate 50 is pulled from the molten salt bath. When the glass sheet storage body 10 is conveyed by the vehicle or the vibration of the glass sheet storage body 10 is raised and lowered by the lifting device, the peripheral edge portions 52 and 54 of the glass sheet 50 are separated from the support members 20A and 20B, thereby causing the glass sheet. Damage or damage (refer to Part C in Figure 1).
於將玻璃板收納體10投入至熔鹽槽中而對玻璃板50之表面進行化學強化後將玻璃板收納體10自熔鹽槽提拉之情形時，熔鹽殘留於成為接觸部位之支持構件20A、20B與玻璃板50之間而污損玻璃表面(參照圖1中之D部)。熔鹽於例如為硝酸鉀(KNO3)之情形時，若溫度下降至熔點以下(334℃以下)，則結晶化而固著。因此，在熔鹽固著於玻璃板50之表面之情形時，難以於其後之步驟中去除固著之熔鹽。 When the glass plate container 10 is placed in a molten salt bath to chemically strengthen the surface of the glass plate 50, and the glass plate container 10 is pulled from the molten salt bath, the molten salt remains in the supporting member which becomes the contact portion. The glass surface is stained between 20A, 20B and the glass plate 50 (refer to the portion D in Fig. 1). When the molten salt is, for example, potassium nitrate (KNO 3 ), if the temperature falls below the melting point (334 ° C or lower), it is crystallized and fixed. Therefore, in the case where the molten salt is fixed to the surface of the glass plate 50, it is difficult to remove the fixed molten salt in the subsequent step.

本發明之課題在於提供一種於上述化學強化處理之前後或處理中與玻璃板之品質降低相關之部位不產生破損或損傷之玻璃板收納體 及化學強化玻璃之製造方法。 An object of the present invention is to provide a glass sheet storage body which does not cause damage or damage to a portion related to a deterioration in quality of a glass sheet before or after the chemical strengthening treatment. And a method for producing chemically strengthened glass.
為了解決上述問題，本發明具有如下手段。 In order to solve the above problems, the present invention has the following means.
本發明係一種玻璃板收納體，其特徵在於：於對複數個玻璃板進行化學強化時被投入至熔鹽中，且包括：收納部，其將上述複數個玻璃板以垂直狀態進行收納；載置部，其設置於該收納部之底部，且載置上述複數個玻璃板之下端；及複數個支持部，其等以支持上述複數個玻璃板之兩側側方之方式朝上述收納部之內側突出；上述複數個支持部係包括接觸於上述玻璃板之周緣部之凸出部，且於上述凸出部之基端部分包括窄細部；上述凸出部向與上述支持部之軸正交之方向凸出。 The present invention relates to a glass plate storage body, which is incorporated in a molten salt when chemically strengthening a plurality of glass plates, and includes a storage portion that accommodates the plurality of glass plates in a vertical state; a portion disposed at a bottom of the accommodating portion and having a lower end of the plurality of glass sheets placed thereon; and a plurality of supporting portions that are supported toward the accommodating portion so as to support both sides of the plurality of glass sheets The plurality of support portions include a protruding portion that contacts the peripheral edge portion of the glass plate, and includes a narrow portion at a base end portion of the protruding portion; the protruding portion is orthogonal to an axis of the support portion The direction is convex.
根據本發明，於化學強化處理之前後或處理中，即便玻璃板之周緣部接觸於支持部之凸出部，玻璃板之周緣部之端面(邊緣)亦為非接觸，從而可防止周緣部端面之破裂並且可防止玻璃板之表面因接觸而產生損傷或擦痕。又，由於以一對支持部之凸出部之間之較窄之間隔保持玻璃板之周緣部，故而可抑制複數個玻璃板之面方向之移位，且以確保各玻璃板之間隔而不妨礙離子交換之方式將各玻璃板呈垂直狀態支持。又，與支持各玻璃板之凸出部之接觸位置成為玻璃板之周緣部之較端面更內側，例如即便玻璃板因振動等而移位，玻璃板之周緣部亦不易自凸出部脫離，因此可防止化學強化處理之前後或處理中之與玻璃板之品質降低相關之部位之破損或損傷。又，由於玻璃板之周緣部接觸於支持部之凸出部之曲線之一部分，故而自熔鹽槽提拉後 熔鹽容易掉落而於玻璃板與支持構件之間不易殘留熔鹽，從而獲得可防止化學強化處理後之玻璃板表面之污損之效果。 According to the present invention, after the chemical strengthening treatment or during the treatment, even if the peripheral portion of the glass sheet contacts the projection of the support portion, the end surface (edge) of the peripheral portion of the glass sheet is non-contact, thereby preventing the end portion of the peripheral portion. It breaks and prevents damage or scratches on the surface of the glass sheet due to contact. Moreover, since the peripheral edge portion of the glass sheet is held at a narrow interval between the projections of the pair of support portions, the displacement of the plurality of glass sheets in the surface direction can be suppressed, and the interval between the glass sheets can be ensured without The glass plates are supported in a vertical state in a manner that hinders ion exchange. Further, the contact position with the projections for supporting the respective glass sheets becomes the inner side of the peripheral end portion of the glass sheet. For example, even if the glass sheet is displaced by vibration or the like, the peripheral edge portion of the glass sheet is less likely to be detached from the protruding portion. Therefore, it is possible to prevent breakage or damage of the portion related to the deterioration of the quality of the glass sheet after the chemical strengthening treatment or during the treatment. Moreover, since the peripheral portion of the glass plate contacts a portion of the curve of the protruding portion of the support portion, the self-melting salt tank is pulled The molten salt is liable to fall and the molten salt is hard to remain between the glass plate and the supporting member, thereby obtaining an effect of preventing the stain on the surface of the glass plate after the chemical strengthening treatment.

以下，參照圖式對用以實施本發明之形態進行說明。 Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings.
圖2係表示本發明之玻璃板收納體之實施形態1之立體圖。如圖2所示，玻璃板收納體100構成為可將複數個玻璃板110(由圖2中之一點鏈線表示)以垂直狀態進行收納，且使用於如下步驟中，即，藉由例如升降裝置(未圖示)下降至熔鹽槽，而將各玻璃板110投入至熔鹽中，從而進行化學強化處理。 Fig. 2 is a perspective view showing a first embodiment of the glass sheet storage body of the present invention. As shown in Fig. 2, the glass sheet storage body 100 is configured such that a plurality of glass sheets 110 (indicated by a dotted line in Fig. 2) can be stored in a vertical state and used in the following steps, that is, by e.g. The apparatus (not shown) is lowered to the molten salt bath, and each of the glass sheets 110 is placed in the molten salt to perform chemical strengthening treatment.
玻璃板收納體100係將複數根支柱102、及複數根樑104、106組合為長方體形狀而成者，且成為於各方向具有複數個開口以使得熔鹽容易流入、流出之構成。再者，支柱102與樑104係根據所收納之玻璃板之尺寸或片數等而任意設定根數或間隔等之組合。 In the glass plate storage body 100, a plurality of pillars 102 and a plurality of beams 104 and 106 are combined into a rectangular parallelepiped shape, and a plurality of openings are formed in each direction so that molten salt can easily flow in and out. In addition, the pillar 102 and the beam 104 are arbitrarily set in combination of the number of the glass sheets, the number of sheets, and the like, and the like.
玻璃板收納體100包括：玻璃板收納部120、玻璃板載置部130、及複數個玻璃板支持機構140。玻璃板收納部120具有如下空間(space)，即，包含由複數根支柱102及複數根樑104所包圍之空間，且可將多個玻璃板110以垂直狀態進行收納。 The glass plate storage body 100 includes a glass plate storage portion 120, a glass plate mounting portion 130, and a plurality of glass plate supporting mechanisms 140. The glass plate accommodating portion 120 has a space including a space surrounded by the plurality of pillars 102 and the plurality of beams 104, and the plurality of glass plates 110 can be housed in a vertical state.
玻璃板載置部130係一對載置板132、134配置於玻璃板收納部120之底部之左右方向(X方向)之兩側，且於中間部分設置有底部開口136。再者，底部開口136係以熔鹽容易自底部側流入至玻璃板收納部120之方式設置，且根據所收納之玻璃板之尺寸或片數等適當設定配置數量或尺寸等。 The glass plate mounting portion 130 is disposed such that the pair of placing plates 132 and 134 are disposed on both sides in the left-right direction (X direction) of the bottom portion of the glass plate housing portion 120, and the bottom opening 136 is provided in the intermediate portion. In addition, the bottom opening 136 is provided so that the molten salt can easily flow from the bottom side to the glass plate accommodating part 120, and the arrangement number, size, etc. are set suitably according to the size, the number of sheets, etc. of the glass plate accommodated.
各玻璃板支持機構140包括：複數根樑106，其等橫架於玻璃板收納部120之側方兩側之中間高度，且用於支持玻璃板；及複數個支持部150，其等每隔特定間隔固定於包圍玻璃板收納部120之各樑106之側壁。各支持部150於所期望之高度位置以固定之間隔整齊排列於Y方向(水平方向)，且朝玻璃板收納部120之內側(X方向)突出。於Y方向上鄰接之一對支持部150之間***成為垂直狀態之玻璃板110之周緣部。 Each of the glass plate supporting mechanisms 140 includes a plurality of root beams 106 that are horizontally placed at an intermediate height between the two sides of the glass plate accommodating portion 120 and supported for the glass plate; and a plurality of support portions 150, etc. The specific interval is fixed to the side wall of each of the beams 106 surrounding the glass sheet accommodating portion 120. Each of the support portions 150 is aligned in the Y direction (horizontal direction) at a predetermined height position at a predetermined height position, and protrudes toward the inner side (X direction) of the glass sheet housing portion 120. A peripheral portion of the glass plate 110 that is in a vertical state is inserted between the pair of support portions 150 adjacent to each other in the Y direction.
於本實施形態中，在玻璃板收納部120之左右兩側於不同之高度位置配置有各玻璃板支持機構140。又，各玻璃板支持機構140之高度方向(Z方向)之配置數量亦可根據玻璃板110之高度方向之尺寸而適當配置於3處或4處。 In the present embodiment, each of the glass plate supporting mechanisms 140 is disposed at different height positions on the left and right sides of the glass plate accommodating portion 120. Moreover, the number of arrangement of the glass plate support mechanisms 140 in the height direction (Z direction) may be appropriately arranged at three or four locations depending on the size of the glass plate 110 in the height direction.
圖3係自正面觀察本發明之玻璃板收納體100之縱剖面圖。如圖3所示，玻璃板110以垂直狀態被收納於玻璃板收納體100之玻璃板收納部120內部，且單面係自左右方向(X方向)之兩側由各2根合計為4根的支持部150支持。又，玻璃板110之下端側之緣部載置於玻璃板載置部130之載置板132、134。 Fig. 3 is a longitudinal sectional view of the glass sheet container 100 of the present invention as seen from the front. As shown in Fig. 3, the glass plate 110 is housed in the glass plate accommodating portion 120 of the glass plate accommodating body 100 in a vertical state, and the total number of the two sides from the left and right directions (X direction) is four. Supported by the support department 150. Moreover, the edge of the lower end side of the glass plate 110 is placed on the mounting plates 132 and 134 of the glass plate mounting part 130.
玻璃板110包含：四方形狀之製品區域112；及周緣部114，其包 圍製品區域之X、Z方向之4條邊。製品區域112為於後續步驟中進行表面處理之非去除預定區域，周緣部114為於後續步驟中被去除之去除預定區域。因此，玻璃板110之周緣部114在後續步驟中被切斷而去除，故而即便接觸於各支持部150亦可順利地供給至後續步驟。 The glass plate 110 includes: a square-shaped product region 112; and a peripheral portion 114, which includes 4 sides of the X and Z directions of the perimeter area. The product region 112 is a non-removed predetermined region subjected to surface treatment in a subsequent step, and the peripheral portion 114 is a removal-predetermined region which is removed in a subsequent step. Therefore, the peripheral edge portion 114 of the glass plate 110 is cut and removed in the subsequent step, so that it can be smoothly supplied to the subsequent step even if it is in contact with each of the support portions 150.
圖4係自上方觀察本發明之玻璃板收納體100之俯視圖。圖5係自側方觀察本發明之玻璃板收納體100之側視圖。如圖4及圖5所示，各支持部150以支持玻璃板110之X方向之兩側側方之方式向玻璃板收納部120之內側突出。因此，玻璃板110以將周緣部114***至自側方突出之一對支持部150之間之方式被支持。又，各玻璃板110雖呈垂直狀態被***，但由於周緣部114之正面或背面接觸於支持部150之外周，故而以相對於垂直線略微傾斜之角度被支持。 Fig. 4 is a plan view of the glass sheet storage body 100 of the present invention as seen from above. Fig. 5 is a side view of the glass sheet storage body 100 of the present invention viewed from the side. As shown in FIGS. 4 and 5 , each of the support portions 150 protrudes inward of the glass plate accommodating portion 120 so as to support both sides of the glass plate 110 in the X direction. Therefore, the glass plate 110 is supported in such a manner that the peripheral portion 114 is inserted between the one of the side protrusions and the support portion 150. Further, although each of the glass sheets 110 is inserted in a vertical state, since the front surface or the back surface of the peripheral edge portion 114 is in contact with the outer circumference of the support portion 150, it is supported at an angle slightly inclined with respect to the vertical line.
一對支持部150之間之最小間隔係如下所述般根據玻璃板110之厚度而形成得相對較窄(儘可能縮小與玻璃板110之表面之間隙)，因此玻璃板110之傾斜被抑制得相對較小。再者，於與鄰接之另一玻璃板110之間形成有不妨礙離子交換之充分之空間(間隔)。又，即便於鄰接之玻璃板110彼此向相反方向傾斜之情形時，亦僅為玻璃板110彼此之上端較下端更接近，而不會相互接觸。 The minimum interval between the pair of support portions 150 is formed to be relatively narrow according to the thickness of the glass plate 110 as described below (to minimize the gap with the surface of the glass plate 110), so that the inclination of the glass plate 110 is suppressed. Relatively small. Further, a sufficient space (interval) that does not interfere with ion exchange is formed between the adjacent glass plate 110. Further, even when the adjacent glass sheets 110 are inclined in opposite directions to each other, only the upper ends of the glass sheets 110 are closer to each other than the lower ends, and are not in contact with each other.
圖6係表示設置於玻璃板收納體100之支持部150之構成之俯視圖。如圖6所示，支持部150包括：凸出部152，其接觸於玻璃板110之周緣部114；及窄細部154，其連接於凸出部152之基端部分。又，凸出部152於外周具有凸狀曲面，且以朝與支持部150之中心軸O正交之方向(徑向)凸出之方式形成。 FIG. 6 is a plan view showing a configuration of the support portion 150 provided in the glass sheet storage body 100. As shown in FIG. 6, the support portion 150 includes a projection portion 152 that contacts the peripheral edge portion 114 of the glass sheet 110, and a narrow portion 154 that is coupled to the base end portion of the projection portion 152. Further, the protruding portion 152 has a convex curved surface on the outer circumference and is formed to protrude in a direction (radial direction) orthogonal to the central axis O of the support portion 150.
進而，支持部150係由對於熔鹽具有化學耐久性之金屬(例如不鏽鋼)形成，其外周面藉由拋光研磨等被加工為不具有凹凸之平滑之面。因此，成為如下構成，即，於將玻璃板收納體100自熔鹽槽提拉 時，附著於支持部150之表面之熔鹽容易掉落，而於支持部150與玻璃板110之接觸部分不易殘留熔鹽。 Further, the support portion 150 is formed of a metal (for example, stainless steel) which is chemically durable to the molten salt, and the outer peripheral surface thereof is processed into a smooth surface having no unevenness by polishing or the like. Therefore, the glass plate storage body 100 is pulled from the molten salt tank. At this time, the molten salt adhering to the surface of the support portion 150 is liable to fall, and the molten salt is less likely to remain in the contact portion between the support portion 150 and the glass plate 110.
再者，支持部150既可將凸出部152與窄細部154形成為一體，或亦可設為將凸出部152與窄細部154加工成各自獨立之零件並組合複數個零件之構成。 Further, the support portion 150 may be formed integrally with the protruding portion 152 and the narrow portion 154, or may be formed by processing the protruding portion 152 and the narrow portion 154 into separate components and combining a plurality of components.
凸出部152係以軸向(X方向)之前端152a與基端152b為最小半徑、前端152a與基端152b之中間部152c為最大半徑之方式形成為外周面向徑向凸出之凸狀曲面。但，此處所言及之半徑係XY平面上之外周面上之相應地點與中心軸O之間之距離，剖面未必限定為圓形。 The protruding portion 152 is formed as a convex curved surface in which the outer circumferential surface faces the radial direction in such a manner that the axial end (X direction) of the front end 152a and the base end 152b is the minimum radius, and the intermediate portion 152c of the front end 152a and the base end 152b is the largest radius. . However, the radius referred to herein is the distance between the corresponding point on the outer circumferential surface of the XY plane and the central axis O, and the cross section is not necessarily limited to a circular shape.
又，前端152a既可如圖6所示般設為具有YZ平面上之平坦面之形狀，亦可設為具有半球狀之曲面之形狀。再者，若前端152a如下述圖8所示般形成為曲面，則最前端成為具有特定之曲率半徑之形狀。因此，於前端152a不具有平坦面之情形時，最前端之半徑為0(mm)。進而，凸出部152只要以中間部分成為最大半徑之方式形成為凸狀曲面即可，因此亦可設為將XY平面上之曲率半徑設為適當任意之半徑、或X方向上之曲率半徑不固定而逐漸變化之形狀。 Further, the front end 152a may have a shape having a flat surface on the YZ plane as shown in FIG. 6, or may have a shape having a hemispherical curved surface. Further, when the distal end 152a is formed into a curved surface as shown in FIG. 8 below, the foremost end has a shape having a specific curvature radius. Therefore, when the front end 152a does not have a flat surface, the radius of the foremost end is 0 (mm). Further, the protruding portion 152 may be formed as a convex curved surface so that the intermediate portion has a maximum radius. Therefore, the radius of curvature in the XY plane may be an appropriate arbitrary radius or the radius of curvature in the X direction may not be Fixed and gradually changing shape.
因此，彼此相鄰之一對支持部150間係前端152a之間及基端152b之間之間隔P1、P2較寬，中間部152c之間之間隔G較窄(G<P1、G<P2)。該間隔G為支持部150之間之最小間隔，且以相對於玻璃板110之厚度成為特定範圍之方式設定。 Therefore, the intervals P1 and P2 between the one end of the support portion 150 and the base end 152b between the adjacent ones of the support portions 150 are wider, and the interval G between the intermediate portions 152c is narrower (G<P1, G<P2). . This interval G is the minimum interval between the support portions 150, and is set so as to be within a specific range with respect to the thickness of the glass plate 110.
又，間隔G變得越小便越可抑制玻璃板110之傾斜，從而可穩定地支持玻璃板110。於本實施形態中，一對支持部150之凸出部152之間之最小間隔(中間部152c之間之間隔G)係相對於玻璃板110之厚度而設定為與玻璃板110之厚度相應之最小間隔。 Further, the smaller the interval G becomes, the more the inclination of the glass plate 110 can be suppressed, and the glass plate 110 can be stably supported. In the present embodiment, the minimum interval between the projections 152 of the pair of support portions 150 (the interval G between the intermediate portions 152c) is set to correspond to the thickness of the glass plate 110 with respect to the thickness of the glass plate 110. Minimum interval.
窄細部154之基端固定於樑106之側壁，前端與凸出部152結合或一體化。又，窄細部154較凸出部152之中間部152c之外徑為小徑，且 於鄰接之窄細部154與樑106之側壁之間形成較寬之退避空間S(由圖6中之虛線表示之區域)。藉由該退避空間S之存在而防止於玻璃板110之周緣部114於支持部150之軸向(X方向)移位時周緣部114之端面(邊緣)接觸於樑106或窄細部154。再者，作為相對於樑106固定窄細部154之方法，既可利用螺栓與螺帽緊固，或亦可使用焊接或接著等任意之固定方法。 The base end of the narrow portion 154 is fixed to the side wall of the beam 106, and the front end is coupled or integrated with the protrusion 152. Moreover, the outer diameter of the narrow portion 154 is smaller than the outer diameter of the intermediate portion 152c of the protruding portion 152, and A wide retreat space S (the area indicated by the broken line in Fig. 6) is formed between the adjacent narrow portion 154 and the side wall of the beam 106. When the peripheral portion 114 of the glass sheet 110 is displaced in the axial direction (X direction) of the support portion 150 by the existence of the evacuation space S, the end surface (edge) of the peripheral portion 114 contacts the beam 106 or the narrow portion 154. Further, as a method of fixing the narrow portion 154 with respect to the beam 106, it may be fastened by a bolt or a nut, or any fixing method such as welding or the like may be used.
此處，對上述凸出部152及窄細部154之各尺寸之設定例進行說明。圖7係表示支持部之各部之尺寸關係及安裝位置之俯視圖。如圖7所示，支持部150之各尺寸L1~L7係如下所述般被決定。 Here, a setting example of the respective sizes of the protruding portion 152 and the narrow portion 154 will be described. Fig. 7 is a plan view showing the dimensional relationship and the mounting position of each portion of the support portion. As shown in FIG. 7, each dimension L1 - L7 of the support part 150 is determined as follows.
尺寸L1為退避空間S之軸向之長度，且為自玻璃板110之端面至樑106之側壁之長度。於本實施形態中，設定為L1=15mm。玻璃板110存在因搬運時或升降時之振動或橫向搖晃而向軸向(X方向)移位之情況。作為此時之移位量，假定為約5~10mm。因此，藉由設為L1=15mm而防止玻璃板110之周緣部114之端面接觸於樑106之側壁。 The dimension L1 is the length of the axial direction of the retreating space S and is the length from the end face of the glass plate 110 to the side wall of the beam 106. In the present embodiment, it is set to L1 = 15 mm. The glass plate 110 may be displaced in the axial direction (X direction) by vibration or lateral shaking during transportation or lifting. As the shift amount at this time, it is assumed to be about 5 to 10 mm. Therefore, the end surface of the peripheral edge portion 114 of the glass plate 110 is prevented from coming into contact with the side wall of the beam 106 by setting L1 = 15 mm.
尺寸L2為凸出部152與玻璃板110在軸向(X方向)上之相對向之長度，且為可支持玻璃板110之周緣部114之區域(可支持範圍)。凸出部152之自前端152a至基端152b之長度係根據玻璃板110之周緣部114之長度而設定。例如，於周緣部114之X方向之長度設為10mm之情形時，留出周緣部114移位時之裕度而設為L2=25mm。例如，於以周緣部114之X方向之中間與為凸出部152中之最大半徑之中間部152c一致之方式載置玻璃板110之情形時，即便玻璃板110向X方向移位約5~10mm，亦可防止周緣部114之端面自凸出部152之前端152a脫離。 The dimension L2 is the length of the convex portion 152 and the glass plate 110 in the axial direction (X direction), and is a region (supportable range) that can support the peripheral edge portion 114 of the glass plate 110. The length of the projection 152 from the front end 152a to the base end 152b is set according to the length of the peripheral edge portion 114 of the glass sheet 110. For example, when the length of the peripheral portion 114 in the X direction is 10 mm, the margin when the peripheral portion 114 is displaced is set to be L2 = 25 mm. For example, when the glass plate 110 is placed in the middle of the X direction of the peripheral portion 114 and the intermediate portion 152c which is the largest radius of the convex portion 152, the glass plate 110 is displaced by about 5 in the X direction. 10 mm can also prevent the end surface of the peripheral portion 114 from being detached from the front end 152a of the projection 152.
尺寸L3為一對支持部150之中心線間距離(軸間距離)，且根據玻璃板110之厚度、及不妨礙藉由熔鹽之流通進行之離子交換之一對玻璃板110之間之面方向之間隔G而設定。於本實施形態中，設定為與一對玻璃板110之間之面方向距離(20mm)相同之尺寸、即設定為L3= 20mm。 The dimension L3 is the distance between the center lines of the pair of support portions 150 (the distance between the axes), and the surface between the glass plates 110 is one of the ions exchanged according to the thickness of the glass plate 110 and the flow of the molten salt. Set by the interval G of the directions. In the present embodiment, the dimension is the same as the surface direction distance (20 mm) between the pair of glass plates 110, that is, it is set to L3= 20mm.
尺寸L4為凸出部152之中間部152c之間之最小間隔，且為支持玻璃板110之接觸點H之間隔。即，尺寸L4為根據玻璃板110之厚度t而決定之凸出部152之間隔G，被規定為t(mm)≦G≦t+5(mm)，且較佳為被規定為t(mm)≦G≦t+3(mm)。例如，於玻璃板110之厚度為t=0.7mm之情形時，L4只要為5.7(mm)以下即可，較佳為只要為3.7(mm)以下即可。於本實施形態中設為L4=3mm。藉此，玻璃板110於一對支持部150間之面方向(Y方向)之可動間隙抑制為5mm以下，較佳為抑制為3mm以下。藉此，即便搬運中之振動傳播，亦將玻璃板110之面方向(Y方向)之搖晃抑制得較小，因此可減小因與凸出部152接觸而產生之接觸壓力。 The dimension L4 is the minimum spacing between the intermediate portions 152c of the projections 152 and is the spacing of the contact points H that support the glass sheet 110. That is, the dimension L4 is the interval G of the projections 152 determined according to the thickness t of the glass plate 110, and is defined as t (mm) ≦ G ≦ t + 5 (mm), and is preferably specified as t (mm). )≦G≦t+3(mm). For example, when the thickness of the glass plate 110 is t=0.7 mm, L4 may be 5.7 (mm) or less, and preferably 3.7 (mm) or less. In the present embodiment, it is set to L4 = 3 mm. Thereby, the movable gap of the glass plate 110 in the surface direction (Y direction) between the pair of support portions 150 is suppressed to 5 mm or less, and it is preferable to suppress it to 3 mm or less. Thereby, even if the vibration during conveyance propagates, the shaking of the surface direction (Y direction) of the glass plate 110 is suppressed small, and the contact pressure by contact with the convex part 152 can be reduced.
尺寸L5為自支持玻璃板110之凸出部152中之具有最大半徑之中間部152c至玻璃板110之端面之距離。即，尺寸L5為與玻璃板110之周緣部114對向之重疊距離，可容許玻璃板110之端面之位置最大達到10mm。 The dimension L5 is the distance from the intermediate portion 152c having the largest radius among the projections 152 of the supporting glass plate 110 to the end faces of the glass sheets 110. That is, the dimension L5 is a distance overlapping the peripheral edge portion 114 of the glass sheet 110, and the position of the end surface of the glass sheet 110 can be allowed to be at most 10 mm.
由於在本實施形態中支持部150之與中心軸O垂直之剖面始終為圓形，故而尺寸L6即為窄細部154之直徑。窄細部154之垂直之剖面形狀雖為圓形，但亦可設為除圓形以外之形狀(例如橢圓形狀)。進而，尺寸L6係以成為可穩定地支持凸出部152之強度之方式設定。於本實施形態中，例如設定為L6=6mm。再者，若增大凸出部152之外徑，則強度提高，但窄細部154相應地變粗而使上述退避空間S變窄，因此考慮退避空間S與強度之平衡而設定為任意之尺寸。 In the present embodiment, the cross section perpendicular to the central axis O of the support portion 150 is always circular, and the dimension L6 is the diameter of the narrow portion 154. The vertical cross-sectional shape of the narrow portion 154 is circular, but may be a shape other than a circular shape (for example, an elliptical shape). Further, the dimension L6 is set so as to stably support the strength of the projection 152. In the present embodiment, for example, L6 = 6 mm is set. Further, when the outer diameter of the protruding portion 152 is increased, the strength is increased, but the narrow portion 154 is thickened accordingly to narrow the evacuation space S. Therefore, the outer space is set to an arbitrary size in consideration of the balance between the retreat space S and the strength. .
尺寸L7為退避空間S之Y方向之寬度，且由上述窄細部154之直徑L6與一對支持部150之中心線O之間之距離(軸間距離)L3規定。於本實施形態中，設為L7=14mm。 The dimension L7 is the width of the retracted space S in the Y direction, and is defined by the distance L6 between the diameter L6 of the narrow portion 154 and the center line O of the pair of support portions 150. In the present embodiment, it is assumed that L7 = 14 mm.
圖8係表示變化例之支持部之各部之尺寸關係及安裝位置之俯視圖。如圖8所示，變化例之支持部150A之各尺寸L1~L7與圖6及圖7所示之支持部150大致相同，但凸出部152A之前端152Aa、中間部152Ac之外形不同。即，前端152Aa係最前端為不具有平坦面之形狀，且形成為半球形狀。而且，中間部152Ac為將前端152Aa與基端152Ab連接之曲面，且形成為如下曲線形狀，即，具有XY平面上之外形並非固定之曲率半徑，而係如抛物線般曲率半徑根據軸向(X方向)之位置而變化之凸狀曲面。 Fig. 8 is a plan view showing the dimensional relationship and the mounting position of each portion of the support portion of the modification. As shown in Fig. 8, each of the dimensions L1 to L7 of the support portion 150A of the modification is substantially the same as the support portion 150 shown in Figs. 6 and 7, but the front end portion 152Aa and the intermediate portion 152Ac of the projection portion 152A are different in shape. That is, the front end 152Aa has a shape having no flat surface and a hemispherical shape. Further, the intermediate portion 152Ac is a curved surface connecting the front end 152Aa and the base end 152Ab, and is formed in a curved shape having a radius of curvature which is not fixed in the XY plane, and a radius of curvature such as a parabola according to the axial direction (X A convex curved surface that changes in position.
又，若前端152Aa形成為前端152a不具有平坦面之曲面，則最前端成為具有特定之曲率半徑之形狀，故而最前端之半徑成為0(mm)。 Further, when the distal end 152Aa is formed such that the distal end 152a does not have a curved surface of a flat surface, the distal end has a shape having a specific curvature radius, and therefore the radius of the foremost end is 0 (mm).
本發明並不限定於圖6及圖7所示之上述實施形態，作為表示設置於玻璃板收納體100之支持部150之各部之尺寸關係及安裝位置之俯視圖，例如亦包含如圖8之形態。如圖8所示，於本變化例中，支持部150A之前端152Aa亦包含無平坦面而不具有寬度之形狀。 The present invention is not limited to the above-described embodiment shown in FIGS. 6 and 7, and is a plan view showing the dimensional relationship and the mounting position of each portion of the support portion 150 provided in the glass sheet storage body 100, and includes, for example, the form of FIG. . As shown in FIG. 8, in the present modification, the front end 152Aa of the support portion 150A also includes a shape having no flat surface and having no width.
再者，如圖7、圖8所示，例如，支持部150、150A之各尺寸L1~L7分別被決定為L1=15mm、L2=29mm、L3=15mm、L4=5.0mm、L5=12.5mm、L6=6.0mm、L7=9.0mm。再者，各尺寸L1~L7之上述數值表示本實施形態之一例，可根據支持部150之形狀或各支持部150之間之間隔等條件而適當設定為所期望之數值。 Further, as shown in FIGS. 7 and 8, for example, the respective dimensions L1 to L7 of the support portions 150 and 150A are determined to be L1 = 15 mm, L2 = 29 mm, L3 = 15 mm, L4 = 5.0 mm, and L5 = 12.5 mm, respectively. , L6 = 6.0 mm, L7 = 9.0 mm. Further, the numerical values of the respective sizes L1 to L7 indicate an example of the present embodiment, and can be appropriately set to a desired value depending on the shape of the support portion 150 or the interval between the support portions 150.
此處，對化學強化處理之前後或處理中之收納於玻璃板收納體100之玻璃板110之狀態進行說明。 Here, the state of the glass plate 110 accommodated in the glass plate accommodation body 100 before or after a chemical strengthening process is demonstrated.
化學強化處理之前後或處理中之各玻璃板110係由配置於玻璃板收納體100之左右方向(X方向之側方)之內側之玻璃板支持機構140之各支持部150呈垂直狀態支持。繼而，玻璃板收納體100藉由升降裝置之升降動作而被投入至熔鹽槽中。藉此，將收納於玻璃板收納體100之內部之各玻璃板110之表面浸漬於被加熱至高溫(400~450℃)之熔 鹽中而進行化學強化處理。對各玻璃板110之化學強化處理係進行預先決定之特定時間。繼而，於完成化學強化處理時，收納於玻璃板收納體100之各玻璃板110藉由升降裝置之升降動作而被自熔鹽槽取出，從而成為化學強化玻璃。 Each of the glass sheets 110 before or after the chemical strengthening treatment is supported by the support portions 150 of the glass sheet supporting mechanism 140 disposed inside the left and right directions (the side in the X direction) of the glass sheet storage body 100 in a vertical state. Then, the glass sheet storage body 100 is put into the molten salt tank by the raising and lowering operation of the lifting device. Thereby, the surface of each glass plate 110 accommodated in the inside of the glass plate accommodation body 100 is immersed in the fuse heated to high temperature (400-450 degreeC). Chemically strengthened in the salt. The chemical strengthening treatment of each of the glass sheets 110 is performed for a predetermined period of time. Then, when the chemical strengthening treatment is completed, each of the glass sheets 110 accommodated in the glass sheet storage body 100 is taken out from the molten salt tank by the lifting operation of the lifting device, and becomes a chemically strengthened glass.
接下來，對化學強化處理之前後或處理中之收納於玻璃板收納體100之玻璃板110與各支持部150之相對位置關係進行說明。 Next, the relative positional relationship between the glass plate 110 accommodated in the glass plate accommodation body 100 before and after the chemical strengthening treatment and each support part 150 is demonstrated.
圖9係表示玻璃板110可相對於各支持部150移位之範圍之俯視圖。如圖9所示，於化學強化處理之前後或處理中，重要的是考慮玻璃板110之最初位置(由實線表示)與玻璃板110之移位後之位置(由虛線表示)之相對位置。於考慮上述相對位置關係之情形時，較理想為，即便玻璃板110相對於自與凸出部152之中間部152c之接觸點H至玻璃板110之端面之最初距離L8向X方向移位，周緣部114亦接觸於接觸點H。即，在本實施形態中，於玻璃板110在周緣部114具有於後續步驟中被去除之去除預定區域之情形時，複數個支持部150將自玻璃板110之緣部至凸出部152之前端之與玻璃板110之表面對向之對向範圍設定為相當於去除預定區域之寬度尺寸(於本實施形態中為10mm)之長度。藉此，於化學強化處理之前後或處理中之搬送動作及升降動作中，與凸出部152之接觸點H位於周緣部114之範圍內。 FIG. 9 is a plan view showing a range in which the glass sheet 110 is displaceable relative to each of the support portions 150. As shown in FIG. 9, it is important to consider the relative position of the initial position of the glass sheet 110 (indicated by the solid line) and the position of the glass sheet 110 after displacement (indicated by a broken line) after the chemical strengthening treatment or during the treatment. . In consideration of the above relative positional relationship, it is preferable that the glass plate 110 is displaced in the X direction with respect to the initial distance L8 from the contact point H with the intermediate portion 152c of the protruding portion 152 to the end surface of the glass plate 110, The peripheral portion 114 is also in contact with the contact point H. That is, in the present embodiment, when the glass plate 110 has the removal of the predetermined region in the peripheral portion 114 in the subsequent step, the plurality of support portions 150 will be from the edge portion of the glass plate 110 to the projection portion 152. The opposing direction of the front end and the surface of the glass plate 110 is set to a length corresponding to the width dimension (10 mm in the present embodiment) of the predetermined region to be removed. Thereby, the contact point H with the protruding portion 152 is located within the range of the peripheral edge portion 114 after the chemical strengthening treatment or during the conveying operation and the lifting operation during the processing.
周緣部114為在後續步驟中被去除之去除預定區域，故而即便於化學強化處理之前後或處理中因與支持部150之接觸而留下損傷或痕跡亦無妨。因此，將玻璃板110***至一對支持部150間時之最初位置係使周緣部114之X方向之中間點、和與凸出部152之中間部152c之接觸點H之位置一致。藉此，即便玻璃板110隨著化學強化處理之前後或處理中之搬送動作及升降動作產生X方向之位置偏移，亦可防止與玻璃板110之品質降低相關之部位之破損或損傷。 The peripheral portion 114 is a removal-predetermined region that is removed in the subsequent step, so that damage or marks may be left due to contact with the support portion 150 after the chemical strengthening treatment or during the treatment. Therefore, the initial position when the glass plate 110 is inserted between the pair of support portions 150 is such that the intermediate point of the peripheral edge portion 114 in the X direction coincides with the position of the contact point H with the intermediate portion 152c of the protruding portion 152. As a result, even if the glass sheet 110 is displaced in the X direction after the chemical strengthening treatment or during the conveyance operation and the lifting operation during the treatment, it is possible to prevent breakage or damage of the portion related to the deterioration of the quality of the glass sheet 110.
圖10係表示玻璃板110之移位與各支持部150之關係之俯視圖。如 圖10所示，於化學強化處理之前後或處理中之搬送動作及升降動作中，例如於玻璃板110向X方向移位之情形時，玻璃板110之周緣部114之表面(正面或背面)以沿著凸出部152之凸狀曲面之方式移位而彎曲成圓弧形狀。藉此，玻璃板110之周緣部114相對於凸出部152之凸狀曲面之接觸壓力減輕，摩擦亦變小。因此，玻璃板110之周緣部114不會因與凸出部152接觸而產生損傷，且亦不會產生擦痕。 FIG. 10 is a plan view showing the relationship between the displacement of the glass sheet 110 and the support portions 150. Such as As shown in FIG. 10, in the case of the transport operation and the lifting operation after the chemical strengthening treatment, for example, when the glass sheet 110 is displaced in the X direction, the surface (front or back) of the peripheral edge portion 114 of the glass sheet 110 is shown. It is displaced in a circular arc shape by being displaced along the convex curved surface of the convex portion 152. Thereby, the contact pressure of the peripheral edge portion 114 of the glass plate 110 with respect to the convex curved surface of the convex portion 152 is reduced, and the friction is also reduced. Therefore, the peripheral edge portion 114 of the glass plate 110 is not damaged by contact with the protruding portion 152, and scratches are not generated.
又，玻璃板110係於面方向(Y方向)之力起作用之情形時，周緣部114成為圓弧形狀，故而與凸出部152之凸狀曲面成為曲面彼此之點接觸，而未如角部般接觸壓力局部地起作用，因此周緣部114之表面之損傷極小。進而，由於玻璃板110之周緣部114之端面可不接觸於樑106之側壁而於退避空間S(參照圖7)內擺動，故而亦可防止端面損傷而抑制破裂之產生。 Further, when the force of the glass plate 110 in the surface direction (Y direction) acts, the peripheral edge portion 114 has an arc shape, so that the convex curved surface of the convex portion 152 is in contact with each other at a curved surface, and is not like a corner. The partial contact pressure acts locally, so the damage of the surface of the peripheral portion 114 is extremely small. Further, since the end surface of the peripheral edge portion 114 of the glass sheet 110 can be swung in the evacuation space S (see FIG. 7) without coming into contact with the side wall of the beam 106, it is possible to prevent the end surface from being damaged and suppress the occurrence of cracking.
即，於化學強化處理之前後或處理中之搬送動作及升降動作中，即便玻璃板110之周緣部114自面方向(Y方向)接觸於支持部150之凸出部152，玻璃板110之周緣部114之端面(邊緣)亦成為非接觸，而可防止周緣部114之端面之破裂。並且，可防止玻璃板110之表面因接觸而產生損傷或擦痕，且可防止與玻璃板110之品質降低相關之部位之破損或損傷。又，由於以一對支持部150之凸出部152間之較窄之間隔G(參照圖6)保持玻璃板110之周緣部114，故而可抑制複數個玻璃板110之面方向(Y方向)之移位。又，能以確保各玻璃板110之面方向之間隔而不妨礙離子交換之方式將各玻璃板110呈垂直狀態支持。如此，藉由將複數個玻璃板110以較窄之間隔呈垂直狀態穩定地支持，而增加每1次化學強化處理中之處理片數從而提高生產效率。 In other words, even before and after the chemical strengthening treatment, the peripheral edge portion 114 of the glass sheet 110 comes into contact with the protruding portion 152 of the support portion 150 from the surface direction (Y direction), and the periphery of the glass sheet 110 The end surface (edge) of the portion 114 also becomes non-contact, and the end surface of the peripheral portion 114 can be prevented from being broken. Further, it is possible to prevent the surface of the glass plate 110 from being damaged or scratched by contact, and it is possible to prevent breakage or damage of the portion related to the deterioration of the quality of the glass plate 110. Further, since the peripheral edge portion 114 of the glass plate 110 is held at a narrow gap G (see FIG. 6) between the projections 152 of the pair of support portions 150, the surface direction (Y direction) of the plurality of glass plates 110 can be suppressed. Shift. Further, each of the glass sheets 110 can be supported in a vertical state so as to ensure the interval between the surface directions of the respective glass sheets 110 without interfering with ion exchange. Thus, by stably supporting a plurality of glass sheets 110 in a vertical state at a narrow interval, the number of processed sheets per chemical strengthening treatment is increased to improve production efficiency.
又，以一對支持部150之凸出部152間之較窄之間隔保持玻璃板110之周緣部114，且於凸出部152之基端側包括窄細部154。因此，與支持各玻璃板110之凸出部152之接觸位置H成為玻璃板110之周緣部 114之較端面更內側(X方向上之中心側)。藉此，例如即便玻璃板110因化學強化處理之前後或處理中之振動等而移位，玻璃板110之周緣部114亦不易自凸出部152脫離。 Further, the peripheral edge portion 114 of the glass plate 110 is held at a narrow interval between the projections 152 of the pair of support portions 150, and the narrow portion 154 is included on the proximal end side of the projection portion 152. Therefore, the contact position H with the projection 152 supporting the respective glass sheets 110 becomes the peripheral portion of the glass sheet 110. The inner end of the 114 is more inward (the center side in the X direction). Thereby, for example, even if the glass plate 110 is displaced by vibration before or after the chemical strengthening treatment or during the treatment, the peripheral edge portion 114 of the glass plate 110 is less likely to be detached from the protruding portion 152.
進而，由於玻璃板110之周緣部114接觸於支持部150之凸出部152之凸狀曲面之一部分，故而於化學強化處理後，在將玻璃板收納體100自熔鹽槽提拉後熔鹽容易掉落，而於玻璃板110與支持部150之間不易殘留熔鹽。因此，可防止因於化學強化處理後將玻璃板收納體100自熔鹽槽提拉後之各玻璃板110之表面之熔鹽而造成之污損。 Further, since the peripheral edge portion 114 of the glass plate 110 is in contact with one of the convex curved surfaces of the convex portion 152 of the support portion 150, after the chemical strengthening treatment, the glass plate storage body 100 is pulled from the molten salt bath and then molten. It is easy to fall, and molten salt is hard to remain between the glass plate 110 and the support part 150. Therefore, it is possible to prevent the contamination caused by the molten salt on the surface of each of the glass sheets 110 after the glass sheet storage body 100 is lifted from the molten salt bath after the chemical strengthening treatment.
又，於圖9、圖10之上述說明中，對使用圖6及圖7所示之支持部150之情形時之作用、效果進行了敍述，但當然，使用上述圖8所示之變化例之支持部150A之情形亦可獲得相同之作用、效果。 Further, in the above description of Figs. 9 and 10, the operation and effect in the case of using the support portion 150 shown in Figs. 6 and 7 have been described. However, it is needless to say that the above-described modification of Fig. 8 is used. The same effect and effect can be obtained in the case of the support unit 150A.
