Description
本發明係關於一種玻璃板搬送裝置及玻璃板搬送方法。 The present invention relates to a glass sheet conveying apparatus and a glass sheet conveying method.
例如,於用於平板顯示器(液晶顯示器或電漿顯示器等)之平板之生產線及平板用玻璃板之生產線中,將複數個搬送輥每隔所需間隔地配置於玻璃板之搬送路徑,將玻璃板一面與設置於各搬送輥之外周之O形環接觸一面進行搬送(例如參照專利文獻1)。 For example, in a production line for a flat panel display (liquid crystal display, plasma display, etc.) and a production line for a flat glass plate, a plurality of transfer rollers are disposed at a required interval to the transport path of the glass plate, and the glass is placed. The plate is conveyed while being in contact with an O-ring provided on the outer circumference of each of the transfer rollers (see, for example, Patent Document 1).
又,各搬送輥之間隔(搬送方向之相隔距離)係考慮由被搬送之玻璃板之厚度或玻璃板之剛性決定之撓曲情況而適當地設定。因此,具有預先決定之厚度之玻璃板於藉由各搬送輥之旋轉而於搬送路徑上搬送之過程中可不落入至搬送輥之下側地於各搬送輥上順利地移動。 Further, the interval between the transfer rollers (the distance between the transport directions) is appropriately set in consideration of the deflection depending on the thickness of the glass plate to be conveyed or the rigidity of the glass plate. Therefore, the glass plate having a predetermined thickness can smoothly move on each of the conveying rollers without falling into the lower side of the conveying roller during the conveyance on the conveying path by the rotation of each conveying roller.
專利文獻1:日本專利特開2007-84282號公報 Patent Document 1: Japanese Patent Laid-Open Publication No. 2007-84282
近年來,作為用於平板之玻璃板,存在厚度進一步變薄之傾向。然而,由於支持各搬送輥之底座係固定於底板面,故即使改變玻璃板之厚度,亦無法根據玻璃板之厚度簡單地調整各搬送輥之搬送方向之間隔。於如此地在搬送路徑上以所需間隔設置有複數個搬送輥之玻璃板搬送裝置中,若即使搬送厚度更薄之玻璃板搬送,亦不調整各 搬送輥之間隔地進行搬送,則玻璃板之厚度方向之剛性將相應於厚度變薄而下降,因此,存在玻璃板之搬送方向之端部(以下亦稱為前側端部)於到達下一個搬送輥之前向下方撓曲,從而無法通過搬送輥之上側之虞。 In recent years, as a glass plate for a flat plate, there is a tendency that the thickness is further reduced. However, since the base supporting each of the conveying rollers is fixed to the bottom surface, even if the thickness of the glass sheet is changed, the interval between the conveying directions of the respective conveying rollers cannot be simply adjusted according to the thickness of the glass sheet. In the glass sheet conveying apparatus in which a plurality of conveying rollers are provided at a desired interval on the conveying path, even if the glass sheet having a thinner thickness is conveyed, the respective sheets are not adjusted. When the conveyance rollers are conveyed at intervals, the rigidity in the thickness direction of the glass sheet is reduced in accordance with the thickness. Therefore, the end portion of the glass sheet in the conveyance direction (hereinafter also referred to as the front end portion) is transferred to the next conveyance. The roller is deflected downward before it, so that it cannot pass through the upper side of the conveying roller.
因此,本發明係鑒於上述情況,以提供一種解決上述問題之玻璃板搬送裝置及玻璃板搬送方法為目的。 Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a glass sheet conveying apparatus and a glass sheet conveying method which solve the above problems.
根據一形態,提供一種玻璃板搬送裝置,其特徵在於:其係將外周配置有與玻璃板接觸之複數個彈性構件之搬送輥每隔所需間隔複數個地配置於上述玻璃板之搬送方向,藉由上述搬送輥之旋轉來搬送上述玻璃板者,且使將上述玻璃板之搬送方向之端部導引為所需高度之帶狀導引構件捲繞於上述複數個搬送輥間,上述帶狀導引構件藉由捲繞於上述複數個彈性構件之間之搬送輥之外周,而與上述搬送輥之旋轉一併行進。 According to one aspect of the invention, a glass sheet conveying apparatus is provided, wherein a conveying roller that has a plurality of elastic members that are in contact with a glass sheet on an outer circumference is disposed in a plurality of required intervals in a conveying direction of the glass sheet. The glass plate is conveyed by the rotation of the conveyance roller, and a belt-shaped guide member that guides an end portion of the glass sheet in a conveyance direction to a desired height is wound between the plurality of conveyance rollers, the belt The guide member is wound around the outer circumference of the transfer roller between the plurality of elastic members, and travels together with the rotation of the transfer roller.
根據本發明,例如即使玻璃板之厚度較薄,玻璃板之端部亦一面與捲繞於複數個搬送輥間之帶狀導引構件接觸,一面被搬送從而導引至搬送輥之上側,因此,可防止玻璃板之端部落入至搬送輥間。 According to the present invention, for example, even if the thickness of the glass plate is thin, the end portion of the glass plate is conveyed and guided to the upper side of the conveying roller while being in contact with the belt-shaped guiding member wound between the plurality of conveying rollers. It can prevent the end of the glass plate from entering the transfer roller.

以下,參照圖式,對用以實施本發明之形態進行說明,但本發明並不受下述實施形態限制,且可在不脫離本發明之範圍之情況下,對下述實施形態施加各種變化及置換。 The embodiments of the present invention are described below with reference to the drawings, but the present invention is not limited by the following embodiments, and various changes may be made to the following embodiments without departing from the scope of the invention. And replacement.
圖1係表示本發明之玻璃板搬送裝置之一實施形態之立體圖。如圖1所示,玻璃板搬送裝置10係於玻璃板G之搬送路徑上,在玻璃板G之搬送方向上每隔所需間隔配置有複數個圓柱形狀之搬送輥20(於圖1中圖示有4根)之構成。各搬送輥20係將圓柱形狀之旋轉軸22插穿至上述各搬送輥20之兩端面之大致中心,且旋轉軸22之兩端部22a及22b藉由底座30之兩端部之支持部32及34以可在同一高度位置旋轉之方式支持。又,於旋轉軸22之右側之端部22b嵌合有一對鏈輪24。 Fig. 1 is a perspective view showing an embodiment of a glass sheet conveying apparatus of the present invention. As shown in Fig. 1, the glass sheet conveying apparatus 10 is disposed on a conveying path of the glass sheet G, and a plurality of cylindrical conveying rollers 20 are disposed at a required interval in the conveying direction of the glass sheet G (in Fig. 1) Shows the composition of 4). Each of the transport rollers 20 inserts a cylindrical rotating shaft 22 into a substantially center of both end faces of the respective conveying rollers 20, and both end portions 22a and 22b of the rotating shaft 22 are supported by the both ends of the base 30. And 34 are supported in such a manner that they can be rotated at the same height position. Further, a pair of sprockets 24 are fitted to the end portion 22b on the right side of the rotating shaft 22.
各鏈輪24係捲繞有鏈條26,且將搬送用馬達40之旋轉驅動力經由減速機構42傳遞至配置於搬送路徑之上游側之鏈輪24。各鏈輪24係由鏈條26在同一方向上同時地進行旋轉驅動,因此,各搬送輥20之旋轉軸22亦與各鏈輪24同樣地在同一方向上同時地被旋轉驅動。 Each of the sprockets 24 is wound around the chain 26, and the rotational driving force of the transport motor 40 is transmitted to the sprocket 24 disposed on the upstream side of the transport path via the speed reduction mechanism 42. Since the sprocket wheels 24 are simultaneously rotationally driven in the same direction by the chain 26, the rotation shafts 22 of the respective conveying rollers 20 are simultaneously rotationally driven in the same direction as the sprocket wheels 24 at the same time.
進而,於各搬送輥20之外周面28,在搬送輥20之軸向上每隔所需間隔地突出形成有供複數個彈性構件50進行嵌合之環狀突出部60。再者,作為彈性構件50,可使用剖面形成為圓形狀之橡膠材、或剖面形成為四邊形狀之橡膠材。進而,彈性構件50係介隔環狀突出部60而配置於搬送輥20之外周面28,但亦可將彈性構件50直接配置於搬送輥20之外周面28。 Further, on the outer peripheral surface 28 of each of the transport rollers 20, an annular projecting portion 60 for fitting a plurality of elastic members 50 is formed at a required interval in the axial direction of the transport roller 20. Further, as the elastic member 50, a rubber material having a circular cross section or a rubber material having a rectangular cross section may be used. Further, the elastic member 50 is disposed on the outer circumferential surface 28 of the conveying roller 20 via the annular protruding portion 60. However, the elastic member 50 may be directly disposed on the outer circumferential surface 28 of the conveying roller 20.
又,為不劃傷玻璃板G,彈性構件50較佳為包含較玻璃柔軟之材質,例如由氟橡膠、乙烯丙烯橡膠、腈橡膠等耐酸性橡膠材形成為環 狀。進而,彈性構件50係摩擦係數高於由樹脂材成型之環狀突出部60,且密接於被搬送之玻璃板G之下表面。因此,參照圖4如下所述,對於被搬送之玻璃板G,越過配置於自搬送輥20之外周面28在半徑方向上突出之位置之彈性構件50之外周,密接地傳遞朝向搬送方向之驅動力。因此,玻璃板G係利用彈性構件50之旋轉而確實地搬送。又,由於將複數個彈性構件50每隔相對較小之間隔地配置於軸向,因此,搬送輥20可與玻璃板G之左右方向(X方向之正交方向)上之複數個部位接觸地保持著大致水平之狀態搬送較薄之玻璃板G。 Further, in order not to scratch the glass sheet G, the elastic member 50 preferably contains a softer material than glass, and is formed of, for example, an acid-resistant rubber material such as fluororubber, ethylene propylene rubber or nitrile rubber. shape. Further, the elastic member 50 has a coefficient of friction higher than that of the annular projecting portion 60 formed of a resin material, and is in close contact with the lower surface of the glass sheet G to be conveyed. Therefore, as described below with reference to FIG. 4, the glass plate G to be conveyed is driven over the outer periphery of the elastic member 50 disposed at a position protruding from the outer peripheral surface 28 of the transfer roller 20 in the radial direction, and the grounded transmission is driven toward the conveyance direction. force. Therefore, the glass plate G is reliably conveyed by the rotation of the elastic member 50. Further, since the plurality of elastic members 50 are disposed in the axial direction at a relatively small interval, the conveying roller 20 can be in contact with a plurality of portions in the left-right direction (the direction orthogonal to the X direction) of the glass sheet G. The thin glass plate G is conveyed while maintaining a substantially horizontal state.
玻璃板G係例如較薄地形成為0.4mm以下、較佳為0.2mm以下、進而較佳為0.1mm以下之厚度。如圖1中單點鏈線所示,將玻璃板G以一主表面(以下亦稱為「下表面」)與各搬送輥20之各彈性構件50之外周接觸之方式在搬送方向(X方向)上進行搬送。又,玻璃板G係因各步驟而搬送方向之長度不同,從而存在搬送方向之長度形成為較長之帶狀之玻璃板、或於搬送過程中切斷為任意尺寸之矩形狀之玻璃板等。 The glass plate G is formed to have a thickness of, for example, 0.4 mm or less, preferably 0.2 mm or less, and more preferably 0.1 mm or less. As shown by the single-dot chain line in Fig. 1, the glass sheet G is in the transport direction (X direction) such that a main surface (hereinafter also referred to as "lower surface") is in contact with the outer periphery of each elastic member 50 of each of the transport rollers 20. ) Transfer on. In addition, the glass plate G has a different length in the transport direction in each step, and a glass plate having a long strip shape in the transport direction or a rectangular glass plate cut into an arbitrary size during transport is used. .
於本實施形態中,於複數個搬送輥20間捲繞有帶狀導引構件70。帶狀導引構件70係為將玻璃板G之搬送方向之端部導引至配置於搬送方向之搬送輥20之彈性構件50的上側外周而設置。帶狀導引構件70係以於玻璃板G之搬送方向延伸之方式捲繞於複數個搬送輥20間。具體而言,複數個帶狀導引構件70係分別捲繞於複數個搬送輥20間。因此,玻璃板G之下表面於玻璃板G通過搬送輥20上時由各彈性構件50支持,並且於玻璃板G即將通過各搬送輥20間之前及剛通過之後由帶狀導引構件70支持。因此,通過複數個搬送輥20間之玻璃板G係由帶狀導引構件70支持而抑制搬送方向之前側端部及後側端部向下方撓曲,並且一面保持大致水平狀態一面被穩定地朝向配置於下游之下一個搬送輥20導引地搬送。 In the present embodiment, the belt-shaped guiding member 70 is wound between the plurality of conveying rollers 20. The belt-shaped guiding member 70 is provided to guide the end portion of the glass sheet G in the conveying direction to the upper outer circumference of the elastic member 50 of the conveying roller 20 disposed in the conveying direction. The belt-shaped guiding member 70 is wound between a plurality of conveying rollers 20 so as to extend in the conveying direction of the glass sheet G. Specifically, a plurality of the strip-shaped guiding members 70 are wound between the plurality of conveying rollers 20, respectively. Therefore, the lower surface of the glass sheet G is supported by the respective elastic members 50 when the glass sheet G passes over the conveying roller 20, and is supported by the belt-shaped guiding member 70 just before and immediately after the glass sheet G passes between the respective conveying rollers 20. . Therefore, the glass plate G between the plurality of conveying rollers 20 is supported by the belt-shaped guiding member 70, and the front end portion and the rear end portion in the conveying direction are prevented from being deflected downward, and are stably maintained while being substantially horizontal. The conveyance is carried out toward the conveyance roller 20 disposed downstream of the downstream.
進而,於本實施形態中,帶狀導引構件70可設為捲繞於搬送輥20之軸向(X方向之正交方向)之至少2個部位以上之構成。藉此,玻璃板G於其下表面之搬送輥20之軸向之至少2個部位以上,與帶狀導引構件70接觸。 Furthermore, in the present embodiment, the belt-shaped guide member 70 can be configured to be wound around at least two of the axial direction of the conveyance roller 20 (the direction orthogonal to the X direction). Thereby, the glass plate G is in contact with the tape-shaped guide member 70 at least two or more places in the axial direction of the conveyance roller 20 of the lower surface.
此處,對將帶狀導引構件70設為捲繞於搬送輥20之軸向之至少2個部位以上之構成之情形的效果進行說明。 Here, an effect of the case where the belt-shaped guide member 70 is configured to be wound around at least two locations in the axial direction of the conveyance roller 20 will be described.
即使於捲繞於複數個搬送輥20間之帶狀導引構件70僅存在於搬送輥20之軸向之1個部位之情形時,亦可藉由玻璃板G被帶狀導引構件70支持,而抑制玻璃板G於搬送方向之前側端部及後側端部向下方撓曲,從而將玻璃板G一面穩定地朝向下一個搬送輥20導引一面進行搬送。 Even when the belt-shaped guiding member 70 wound between the plurality of conveying rollers 20 exists only in one portion of the axial direction of the conveying roller 20, it can be supported by the belt-shaped guiding member 70 by the glass sheet G. In addition, the side end portion and the rear end portion of the glass sheet G are deflected downward in the conveyance direction, and the glass sheet G is stably guided toward the next conveyance roller 20 to be conveyed.
然而,可藉由將帶狀導引構件70設為捲繞於搬送輥20之軸向之至少2個部位以上之構成,而使玻璃板G於搬送輥20之軸向之2個部位以上由帶狀導引構件70支持,從而可更穩定地搬送玻璃板G。藉此,例如可更良好地防止以下情況:玻璃板G之與帶狀導引構件70分隔之部分於玻璃板G之搬送方向端部朝向下方撓曲,無法通過位於搬送方向下游側之下一個搬送輥20之上側,而與搬送輥20接觸導致破損。 However, the strip-shaped guide member 70 can be formed by winding at least two or more portions in the axial direction of the conveying roller 20, and the glass sheet G can be made of two or more portions in the axial direction of the conveying roller 20 The belt guide member 70 is supported so that the glass sheet G can be conveyed more stably. By this, for example, it is possible to prevent the portion of the glass sheet G that is separated from the belt-shaped guide member 70 from being deflected downward in the conveying direction end portion of the glass sheet G, and cannot pass through the lower side in the downstream side in the conveying direction. The upper side of the conveying roller 20 is in contact with the conveying roller 20 to cause breakage.
因此,於本實施形態中,可以將帶狀導引構件70配置於搬送輥20之軸向之兩端部之至少2個部位之方式,將複數個帶狀導引構件70分別捲繞於複數個搬送輥20間。進而,可以將帶狀導引構件70配置於搬送輥20之軸向之兩端部及中央部之3個部位之方式,將複數個帶狀導引構件70分別捲繞於複數個搬送輥20間。又,複數個帶狀導引構件70可捲繞於搬送輥20之相對軸向之中央部左右對稱之位置。 Therefore, in the present embodiment, the plurality of strip-shaped guide members 70 may be wound around the plurality of strip-shaped guide members 70 so that the strip-shaped guide members 70 are disposed at at least two portions of the axial end portions of the transport roller 20 There are 20 transfer rollers. Further, the belt-shaped guiding members 70 may be disposed on the both end portions of the axial direction of the conveying roller 20 and the three portions of the center portion, and the plurality of belt-shaped guiding members 70 may be wound around the plurality of conveying rollers 20, respectively. between. Further, the plurality of belt-shaped guiding members 70 can be wound around the center portion of the conveying roller 20 in the axial direction of the opposite direction.
再者,於帶狀導引構件70僅存在於搬送輥20之軸向之1個部位之情形時,可將帶狀導引構件70捲繞於搬送輥20之軸向之中央部。 In the case where the belt-shaped guide member 70 is present only in one portion of the axial direction of the conveyance roller 20, the belt-shaped guide member 70 can be wound around the center portion of the conveyance roller 20 in the axial direction.
將複數個帶狀導引構件70設為以配置於搬送輥20之軸向之兩端 部之至少2個部位之方式,分別捲繞於複數個搬送輥20間之構成,藉此,玻璃板G之下表面於玻璃板G通過搬送輥20上時由各彈性構件50支持,並且於玻璃板G即將通過各搬送輥20間之前及剛通過之後,成為由複數個帶狀導引構件70支持。因此,通過複數個搬送輥20間之玻璃板G藉由複數個帶狀導引構件70支持,從而抑制搬送方向之前側端部及後側端部朝向下方撓曲,並且一面保持大致水平狀態一面被穩定地朝向配置於下游之下一個搬送輥20導引地進行搬送。 A plurality of strip-shaped guiding members 70 are disposed at both ends of the axial direction of the conveying roller 20 At least two portions of the portion are wound between the plurality of conveying rollers 20, whereby the lower surface of the glass sheet G is supported by the elastic members 50 when the glass sheet G passes over the conveying roller 20, and The glass sheet G is supported by a plurality of strip-shaped guiding members 70 immediately before and immediately after passing between the respective conveying rollers 20. Therefore, the glass plate G between the plurality of conveying rollers 20 is supported by the plurality of belt-shaped guiding members 70, thereby suppressing the front end portion and the rear end portion in the conveying direction from being deflected downward, while maintaining a substantially horizontal state. It is conveyed stably guided toward the conveyance roller 20 arrange|positioned downstream.
進而,各帶狀導引構件70係捲繞於各搬送輥20之上游側及下游側之搬送方向。因此,參照圖4如下所述,於搬送過程中,玻璃板G之前側端部由捲繞於一搬送輥20之上游側之各帶狀導引構件70支持,玻璃板G之後側端部由捲繞於該一搬送輥20之下游側之各帶狀導引構件70支持。因此,玻璃板G於通過搬送路徑之過程中,一面藉由搬送輥20之各彈性構件50、該搬送輥20之上游側之各帶狀導引構件70、及該搬送輥20之下游側之各帶狀導引構件70適當地支持複數個部位,一面將前側端部及後側端部以不與搬送輥20碰撞之方式導引,穩定地向下一個搬送輥20搬送。 Further, each of the strip-shaped guiding members 70 is wound around the upstream side and the downstream side of the respective conveying rollers 20 in the conveying direction. Therefore, as described below with reference to Fig. 4, in the conveyance process, the front end portion of the glass sheet G is supported by the respective belt-shaped guiding members 70 wound on the upstream side of a conveying roller 20, and the rear end portion of the glass sheet G is Each of the strip-shaped guiding members 70 wound on the downstream side of the one conveying roller 20 is supported. Therefore, in the process of passing through the transport path, the glass sheet G passes through the elastic members 50 of the transport roller 20, the strip-shaped guide members 70 on the upstream side of the transport roller 20, and the downstream side of the transport roller 20. Each of the strip-shaped guide members 70 appropriately supports the plurality of portions, and guides the front end portion and the rear end portion so as not to collide with the conveyance roller 20, and stably conveys the conveyance to the next conveyance roller 20.
又,各帶狀導引構件70係捲繞於各搬送輥20之彈性構件50間之外周面28,且以成為厚度低於彈性構件50之位置之方式形成為較薄之帶狀。再者,各帶狀導引構件70為不劃傷玻璃板G,而包含較玻璃柔軟之材質之樹脂製帶、橡膠製帶、或布製帶等。進而,各帶狀導引構件70成為長邊方向之兩端部彼此由面狀扣件(hook and loop fastener,卡鉤及環圈扣件)結合而成之環形狀。一個帶狀導引構件70由一條帶、或使2條以上之帶結合而形成。 Further, each of the strip-shaped guiding members 70 is wound around the outer peripheral surface 28 between the elastic members 50 of the respective conveying rollers 20, and is formed into a thin strip shape so as to have a thickness lower than that of the elastic member 50. Further, each of the strip-shaped guiding members 70 is a resin tape, a rubber tape, a cloth tape or the like which does not scratch the glass sheet G and is made of a glass soft material. Further, each of the strip-shaped guide members 70 has a ring shape in which both end portions in the longitudinal direction are combined with a hook and a loop fastener (a hook and a loop fastener). A belt-shaped guiding member 70 is formed by a belt or a combination of two or more belts.
各帶狀導引構件70可藉由面狀扣件簡單地結合或解除結合,因此,可設置於各搬送輥20之任意部位,並且亦可容易地改變設置部位。又,各帶狀導引構件70可捲繞於一對搬送輥20間,若總長存在寬 裕,則亦可捲繞於三個搬送輥20間。 Each of the strip-shaped guiding members 70 can be simply joined or uncoupled by the planar fasteners, and therefore, can be provided at any portion of each of the conveying rollers 20, and the installation portion can be easily changed. Further, each of the strip-shaped guiding members 70 can be wound between a pair of conveying rollers 20, and if the total length is wide Yu can also be wound between three transfer rolls 20.
再者,複數個帶狀導引構件70可設為以使玻璃板G之下表面之相同部位不連續地接觸於帶狀導引構件70之方式,將搬送輥20之軸向之捲繞位置無規地錯開進行配置之構成,。因此,由於避免玻璃板G之下表面之相同部位接觸於帶狀導引構件70,因此,將玻璃板G以不易產生與帶狀導引構件70接觸所導致之痕跡之方式搬送。又,帶狀導引構件70係以與玻璃板G相同之速度於搬送方向行進,因此可避免帶狀導引構件70與玻璃板G之摩擦,從而以不易產生與帶狀導引構件70之接觸所導致之痕跡之方式進行搬送。又,由於帶狀導引構件70係由較玻璃板G柔軟之材質(例如樹脂帶或布製帶等)而形成,因此,更不易於玻璃板G之下表面產生上述痕跡。 Further, the plurality of strip-shaped guiding members 70 may be arranged such that the same position of the lower surface of the glass sheet G is discontinuously contacted with the strip-shaped guiding member 70, and the winding position of the conveying roller 20 in the axial direction is set. Randomly staggered the configuration of the configuration. Therefore, since the same portion of the lower surface of the glass sheet G is prevented from coming into contact with the belt-shaped guiding member 70, the glass sheet G is conveyed so as not to cause a trace caused by contact with the belt-shaped guiding member 70. Further, since the belt-shaped guiding member 70 travels at the same speed as the glass sheet G in the conveying direction, the friction between the belt-shaped guiding member 70 and the glass sheet G can be avoided, so that the belt-shaped guiding member 70 is less likely to be generated. Carrying in the way of contact with the traces caused by the contact. Further, since the belt-shaped guiding member 70 is formed of a material softer than the glass sheet G (for example, a resin tape or a cloth tape, etc.), it is less likely that the above-described marks are generated on the lower surface of the glass sheet G.
以下,以將帶狀導引構件70設為捲繞於搬送輥20之軸向之至少2個部位以上之構成之情形為例進行說明。 Hereinafter, a case where the belt-shaped guide member 70 is configured to be wound around at least two portions of the conveyance roller 20 in the axial direction will be described as an example.
圖2係自搬送方向觀察玻璃板G與玻璃板搬送裝置10之搬送輥20之彈性構件50的外周接觸之狀態、及藉由帶狀導引構件70所導引之玻璃板G所得之前視圖。如圖2(A)所示,玻璃板G於通過搬送輥20時,一面與嵌合於環狀突出部60之各彈性構件50之外周滑接一面被搬送。又,帶狀導引構件70係捲繞於厚度H1較各彈性構件50之外周高度H2低之位置上所形成之外周面28。換言之,由於帶狀導引構件70之厚度H1薄於自搬送輥20之外周至彈性構件50之外周為止之高度H2,因此,帶狀導引構件70於搬送輥20附近不與玻璃板G接觸(H1<H2)。 2 is a front view showing a state in which the glass plate G is in contact with the outer periphery of the elastic member 50 of the conveying roller 20 of the glass sheet conveying device 10 and a glass plate G guided by the belt-shaped guiding member 70. As shown in FIG. 2(A), when the glass sheet G passes through the conveying roller 20, it is conveyed while being slidably attached to the outer periphery of each of the elastic members 50 fitted to the annular projecting portion 60. Further, the belt-shaped guiding member 70 is wound around the outer circumferential surface 28 formed at a position where the thickness H1 is lower than the outer circumferential height H2 of each elastic member 50. In other words, since the thickness H1 of the belt-shaped guiding member 70 is thinner than the height H2 from the outer circumference of the conveying roller 20 to the outer circumference of the elastic member 50, the belt-shaped guiding member 70 is not in contact with the glass sheet G in the vicinity of the conveying roller 20. (H1 < H2).
進而,如圖2(A)所示,由於自外周面28在半徑方向上突出且配置於搬送輥20之軸向之各彈性構件50之間隔較窄,因此,於玻璃板G通過各搬送輥20時,玻璃板G與各彈性構件50之外周滑接而成為大致水平狀態。因此,於搬送輥20附近,玻璃板G並非始終與各帶狀導引構件70接觸,而於通過搬送輥20間時,與各帶狀導引構件70部分地接 觸,因此,不易殘留與各帶狀導引構件70之接觸造成之痕跡。 Further, as shown in FIG. 2(A), since the interval between the elastic members 50 which are protruded in the radial direction from the outer peripheral surface 28 and disposed in the axial direction of the conveying roller 20 is narrow, the glass sheet G passes through the respective conveying rollers. At 20 o'clock, the glass sheet G is slidably connected to the outer periphery of each elastic member 50, and is in a substantially horizontal state. Therefore, in the vicinity of the conveying roller 20, the glass sheet G is not always in contact with the respective belt-shaped guiding members 70, and is partially connected to the respective belt-shaped guiding members 70 when passing between the conveying rollers 20. Therefore, it is difficult to leave traces caused by contact with the respective belt-shaped guiding members 70.
又,各帶狀導引構件70係與搬送方向正交之寬度L1設定為環狀突出部60間距離L2以下(L1<L2)。 Moreover, the width L1 of each of the strip-shaped guide members 70 orthogonal to the conveyance direction is set to be equal to or smaller than the distance L2 between the annular projections 60 (L1 < L2).
如圖2(B)所示,玻璃板G係於下表面由一對帶狀導引構件70導引2個部位之情形時,藉由各帶狀導引構件70而以於左右方向(圖1之X方向之正交方向)對稱之方式,導引左右兩側之周緣部附近,從而成為帶狀導引構件70間之中央部分向下方撓曲之狀態。因此,玻璃板G係將以保持左右之平衡之方式將左右對稱之2個部位頂起。 As shown in FIG. 2(B), when the glass plate G is guided by the pair of belt-shaped guiding members 70 on the lower surface, the belt-shaped guiding members 70 are used in the left-right direction (Fig. In the symmetrical manner of the X direction of the first direction, the vicinity of the peripheral portion of the left and right sides is guided, and the central portion between the strip-shaped guiding members 70 is deflected downward. Therefore, the glass plate G is used to push up the two sides of the left and right symmetry so as to maintain the balance between the right and left.
如圖2(C)所示,玻璃板G係於下表面由帶狀導引構件70導引3個部位之情形時,藉由各帶狀導引構件70而以於左右方向(圖1之X方向之正交方向)對稱之方式,導引左右兩側之周緣部附近及帶狀導引構件70間之中央部分,因此,成為各帶狀導引構件70間略微向下方撓曲之狀態。因此,玻璃板G係以保持左右方向之平衡之方式,將3個部位頂起。與玻璃板G之下表面之接觸面積將隨著增加帶狀導引構件70之數量而增加,從而可使朝向下方之撓曲變小。 As shown in Fig. 2(C), when the glass plate G is guided by the strip-shaped guiding member 70 at the lower surface, the strip-shaped guiding member 70 is used in the left-right direction (Fig. 1). In the symmetrical manner in the X direction, the vicinity of the peripheral portion on the left and right sides and the central portion between the strip-shaped guiding members 70 are guided, and thus the strip guiding members 70 are slightly deflected downward. . Therefore, the glass plate G is pushed up by three parts so as to maintain the balance in the left-right direction. The contact area with the lower surface of the glass sheet G will increase as the number of the strip-shaped guiding members 70 is increased, so that the downward deflection becomes small.
因此,如圖2(B)、(C)所示,玻璃板G於在搬送輥20間搬送之過程中,左右方向上之兩端附近之2個部位、或左右方向之兩端附近及中央附近之3個部位接觸於帶狀導引構件70,從而限制高度位置,並且於通過搬送輥20附近時,藉由帶狀導引構件70而被導引至各彈性構件50之上側外周,進而與各彈性構件50之外周接觸地被搬送。 Therefore, as shown in FIGS. 2(B) and 2(C), the glass sheet G is transported between the transport rollers 20, in the vicinity of both ends in the left-right direction, or in the vicinity of the two ends in the left-right direction and in the center. The three adjacent portions are in contact with the belt-shaped guiding member 70 to restrict the height position, and when passing through the vicinity of the conveying roller 20, are guided to the outer periphery of each elastic member 50 by the belt-shaped guiding member 70, thereby It is conveyed in contact with the outer periphery of each elastic member 50.
又,由於帶狀導引構件70係設置於彈性構件50間,故帶狀導引構件70之寬度L1(圖1之X方向之正交方向之尺寸)於彈性構件50間距離以下具有所需之寬度尺寸。因此,帶狀導引構件70於與玻璃板G之下表面接觸時,可相應於與玻璃板G之接觸面積,避免該接觸部分中之應力集中,從而穩定地支持玻璃板G之荷重。 Further, since the belt-shaped guiding member 70 is disposed between the elastic members 50, the width L1 of the belt-shaped guiding member 70 (the dimension in the direction orthogonal to the X direction in Fig. 1) is required to be equal to or less than the distance between the elastic members 50. The width dimension. Therefore, when the strip-shaped guiding member 70 comes into contact with the lower surface of the glass sheet G, it can correspond to the contact area with the glass sheet G, and the stress concentration in the contact portion is prevented, thereby stably supporting the load of the glass sheet G.
圖3係表示藉由捲繞於各搬送輥20間之帶狀導引構件70所導引之 玻璃板G之搬送路徑的平面圖。如圖3所示,搬送輥20間之各帶狀導引構件70之捲繞方向較佳為與玻璃板G之搬送方向(X方向)、及搬送輥20之旋轉方向平行。若各帶狀導引構件70之捲繞方向與玻璃板G之搬送方向、及搬送輥20之旋轉方向平行,則玻璃板G由搬送輥20搬送之搬送方向與各帶狀導引構件70之旋轉方向一致,玻璃板G之下表面不被各帶狀導引構件70刮擦,因此,變得更不易於玻璃板G之下表面產生痕跡。 Figure 3 is a view showing the belt guide member 70 wound between the respective conveying rollers 20. Plan view of the transport path of the glass plate G. As shown in FIG. 3, the winding direction of each of the belt-shaped guiding members 70 between the conveying rollers 20 is preferably parallel to the conveying direction (X direction) of the glass sheet G and the rotation direction of the conveying roller 20. When the winding direction of each of the strip-shaped guiding members 70 is parallel to the conveying direction of the glass sheet G and the rotation direction of the conveying roller 20, the conveying direction of the glass sheet G by the conveying roller 20 and the belt-shaped guiding members 70 are The rotation directions are uniform, and the lower surface of the glass sheet G is not scratched by the respective belt-shaped guiding members 70, and therefore, it becomes less likely that traces are formed on the lower surface of the glass sheet G.
又,為維持各帶狀導引構件70之平行,較佳為將與搬送方向正交之寬度L1設定為所需尺寸(例如L1=20mm以上且為鄰接之環狀突出部60間距離L2(示於圖2(A))以下)。 Moreover, in order to maintain the parallelism of each of the strip-shaped guide members 70, it is preferable to set the width L1 orthogonal to the conveyance direction to a desired size (for example, L1 = 20 mm or more and the distance L2 between the adjacent annular projections 60 ( Shown in Figure 2 (A)) below).
圖4係表示藉由捲繞於各搬送輥20間之帶狀導引構件70所導引之玻璃板G之搬送動作的側視圖。再者,於圖4中,省略底座30、鏈輪24、鏈條26、及搬送用馬達40之圖示。又,此處,對玻璃板G之搬送方向(X方向)之長度形成為較短,且玻璃板G之搬送方向之前側端部與後側端部通過搬送輥20之過程進行說明。 FIG. 4 is a side view showing a conveying operation of the glass sheet G guided by the belt-shaped guiding member 70 wound between the respective conveying rollers 20. In addition, in FIG. 4, illustration of the base 30, the sprocket 24, the chain 26, and the conveyance motor 40 is abbreviate|omitted. Here, the length of the glass sheet G in the transport direction (X direction) is formed to be short, and the process of the front end portion and the rear end portion of the glass sheet G in the transport direction passing through the transport roller 20 will be described.
如圖4(A)所示,若搬送用馬達40(參照圖1)之旋轉驅動力傳遞至搬送輥20A及20B(與圖1~圖3之搬送輥20區別而記載),使搬送輥20A及20B於圖4上逆時針方向地旋轉驅動,則將玻璃板G以下表面與第一個(上游側)搬送輥20A之各彈性構件50之外周接觸地在X方向(搬送輥20之旋轉方向)上搬送。此時,玻璃板G係X方向之大致中間部分與彈性構件50之外周接觸,被傳遞彈性構件50之旋轉驅動力,從而在X方向上搬送。又,玻璃板G之搬送方向之前側端部G1係與捲繞於第一個搬送輥20A與第二個(下游側)搬送輥20B之間之複數個帶狀導引構件70B接觸,且以不落入至高度位置比搬送輥20A之外周面28低之位置之方式被導引。又,玻璃板G之搬送方向之後側端部G2亦同樣地與捲 繞於第一個搬送輥20A之上游側之複數個帶狀導引構件70A接觸,且以不落入至高度位置比第一個搬送輥20A之外周面28低之位置之方式被導引。藉此,玻璃板G之後側端部G2可利用各帶狀導引構件70A,防止下垂至第一個搬送輥20A之下側。 As shown in Fig. 4 (A), when the rotational driving force of the transport motor 40 (see Fig. 1) is transmitted to the transport rollers 20A and 20B (described separately from the transport rollers 20 of Figs. 1 to 3), the transport roller 20A is placed. When the 20B is rotationally driven in the counterclockwise direction in FIG. 4, the lower surface of the glass sheet G is in contact with the outer circumference of each of the elastic members 50 of the first (upstream side) conveying roller 20A in the X direction (the rotation direction of the conveying roller 20). ) on the transfer. At this time, the substantially intermediate portion of the glass sheet G in the X direction is in contact with the outer circumference of the elastic member 50, and the rotational driving force of the elastic member 50 is transmitted to be conveyed in the X direction. Further, the front end portion G1 of the glass sheet G in the transport direction is in contact with a plurality of strip-shaped guide members 70B wound between the first transport roller 20A and the second (downstream) transport roller 20B, and It is guided so as not to fall to a position where the height position is lower than the outer peripheral surface 28 of the conveying roller 20A. Further, the rear end portion G2 of the glass sheet G in the transport direction is similarly wound The plurality of strip-shaped guide members 70A that are wound around the upstream side of the first transport roller 20A are in contact with each other, and are guided so as not to fall to a position where the height position is lower than the outer peripheral surface 28 of the first transport roller 20A. Thereby, the rear end portion G2 of the glass sheet G can be prevented from sagging to the lower side of the first conveying roller 20A by the respective belt-shaped guiding members 70A.
於該搬送狀態下,玻璃板G之前側端部G1係由下游側之各帶狀導引構件70B支持,且搬送方向之中間部分由搬送輥20A之各彈性構件50驅動,後側端部G2由上游側之各帶狀導引構件70A支持。因此,玻璃板G即便於中間部分被頂起之狀態下產生撓曲,亦保持大致水平之狀態地被搬送。 In the conveyance state, the front end portion G1 of the glass sheet G is supported by the belt-shaped guide members 70B on the downstream side, and the intermediate portion of the conveyance direction is driven by the elastic members 50 of the conveyance roller 20A, and the rear end portion G2 is driven. It is supported by each of the strip-shaped guiding members 70A on the upstream side. Therefore, even if the glass plate G is deflected in a state in which the intermediate portion is lifted up, it is conveyed while maintaining a substantially horizontal state.
如圖4(B)所示,若於X方向上搬送玻璃板G,則玻璃板G之搬送方向之前側端部G1與捲繞於搬送輥20A及20B間之帶狀導引構件70B接觸而限制高度位置,且後側端部G2與自第一個搬送輥20A之外周面28在半徑方向上突出之彈性構件50之上側外周(相較旋轉中心為上側)接觸,被傳遞X方向之驅動力。於該搬送狀態下,玻璃板G係前側端部G1由下游側之各帶狀導引構件70B支持,且搬送方向之中間部分自搬送輥20A之各彈性構件50分開,後側端部G2與搬送輥20A之各彈性構件50接觸地被驅動。因此,玻璃板G即便成為中間部分懸浮之狀態,亦將前側端部G1及後側端部G2保持大致水平之狀態地進行搬送。 As shown in FIG. 4(B), when the glass sheet G is conveyed in the X direction, the front end portion G1 in the conveyance direction of the glass sheet G is in contact with the belt-shaped guide member 70B wound between the conveyance rollers 20A and 20B. The height position is restricted, and the rear end portion G2 is in contact with the upper side of the upper side of the elastic member 50 that protrudes in the radial direction from the outer peripheral surface 28 of the first conveying roller 20A (the upper side is closer to the center of rotation), and is driven in the X direction. force. In the conveyance state, the front end portion G1 of the glass sheet G is supported by the belt-shaped guide members 70B on the downstream side, and the intermediate portion of the conveyance direction is separated from the elastic members 50 of the conveyance roller 20A, and the rear end portion G2 and Each of the elastic members 50 of the conveying roller 20A is driven in contact. Therefore, even if the glass plate G is in a state in which the intermediate portion is suspended, the front end portion G1 and the rear end portion G2 are conveyed in a substantially horizontal state.
如圖4(C)所示,若進一步在X方向搬送玻璃板G,則玻璃板G之搬送方向之前側端部G1藉由帶狀導引構件70B而導引至第2個搬送輥20B之上側(相較旋轉中心為上側),從而與圖4上逆時針方向轉動之彈性構件50之外周接觸。與此同時,前側端部G1自彈性構件50被傳遞旋轉方向之驅動力得以,一面被頂起至帶狀導引構件70B之上方一面在X方向移動。又,後側端部G2與捲繞於搬送輥20A及20B間之帶狀導引構件70B接觸,從而導引高度位置。於該搬送狀態下,玻璃板G係前側端部G1由第2個搬送輥20A之各彈性構件50驅動,且搬送方向之 中間部分自各帶狀導引構件70B懸浮之狀態,且後側端部G2由上游側之各帶狀導引構件70B支持。因此,玻璃板G即便成為中間部分懸浮之狀態,亦將前側端部G1及後側端部G2保持大致水平狀態地搬送。 As shown in FIG. 4(C), when the glass sheet G is further conveyed in the X direction, the front end portion G1 of the glass sheet G in the conveyance direction is guided to the second conveyance roller 20B by the belt-shaped guide member 70B. The upper side (the upper side than the center of rotation) is in contact with the outer periphery of the elastic member 50 which is rotated counterclockwise in FIG. At the same time, the front end portion G1 is transmitted from the elastic member 50 in the rotational direction, and is moved in the X direction while being lifted up above the belt-shaped guiding member 70B. Further, the rear end portion G2 is in contact with the belt-shaped guide member 70B wound between the conveyance rollers 20A and 20B to guide the height position. In the conveyance state, the front end portion G1 of the glass sheet G is driven by the elastic members 50 of the second transfer roller 20A, and the conveyance direction is The intermediate portion is suspended from the respective belt-shaped guiding members 70B, and the rear-side end portion G2 is supported by the respective belt-shaped guiding members 70B on the upstream side. Therefore, even if the glass plate G is in a state in which the intermediate portion is suspended, the front end portion G1 and the rear end portion G2 are conveyed in a substantially horizontal state.
圖4(D)所示,若進而在X方向上搬送玻璃板G,則玻璃板G以搬送方向之大致中間部分之下表面與第2個搬送輥20B之彈性構件50之外周接觸之方式在X方向被搬送。此時,玻璃板G之搬送方向之前側端部G1與捲繞於下游側之搬送輥20間之各帶狀導引構件70C接觸,以不落入至高度位置低於搬送輥20B之外周面28之位置之方式被導引。又,玻璃板G之搬送方向之後側端部G2亦同樣地,與上游側之各帶狀導引構件70B接觸,以不落入至高度位置低於搬送輥20B之外周面28之位置之方式被導引。藉此,防止玻璃板G之前側端部G1於上述搬送過程中,嵌入至第2個搬送輥B之下側。 As shown in Fig. 4(D), when the glass sheet G is further conveyed in the X direction, the glass sheet G is in contact with the outer surface of the elastic member 50 of the second conveying roller 20B in the lower middle surface of the substantially intermediate portion in the conveying direction. The X direction is carried. At this time, the belt-side guide member 70C between the front end portion G1 in the conveyance direction of the glass sheet G and the conveyance roller 20 wound on the downstream side comes into contact with each other so as not to fall to the height position lower than the outer circumference of the conveyance roller 20B. The way of the position of 28 is guided. In addition, the rear end portion G2 of the glass sheet G in the transport direction is also in contact with each of the strip-shaped guide members 70B on the upstream side so as not to fall to a position where the height position is lower than the outer peripheral surface 28 of the transport roller 20B. Being guided. Thereby, the front end part G1 of the glass plate G is prevented from being fitted to the lower side of the 2nd conveyance roller B in the said conveyance process.
如此般,玻璃板G係前側端部G1及後側端部G2與捲繞於各搬送輥20間之各帶狀導引構件70A~70C接觸,並且一面導引高度位置一面進行搬送,因此,亦於搬送輥20間搬送時,以不下降至低於搬送輥20之外周面28之位置方式受到限制,從而防止與搬送輥20碰撞。 In this manner, the front end portion G1 and the rear end portion G2 of the glass sheet G are in contact with the respective belt-shaped guiding members 70A to 70C wound between the respective conveying rollers 20, and are conveyed while guiding the height position. When the conveyance rollers 20 are transported between the conveyance rollers 20, they are restricted so as not to fall below the outer circumferential surface 28 of the conveyance roller 20, thereby preventing collision with the conveyance roller 20.
又,若玻璃板G之厚度變薄(例如厚度為0.4mm以下),則玻璃板G之剛性降低,因此,與各帶狀導引構件70接觸之部分以外成為略微向下方撓曲之狀態地被搬送。再者,玻璃板G係如上述之圖2(B)、(C)所示,由於各帶狀導引構件70以於搬送輥20之軸向,左右對稱之方式配置,且將帶狀導引構件70與玻璃板G之搬送方向(搬送輥20之旋轉方向)平行地捲繞,因此,以保持玻璃板G之左右方向(與搬送方向正交之方向)之平衡之方式,將複數個部位頂起,故而不會較大地下降。又,由於玻璃板G之前側端部G1係與帶狀導引構件70一併於搬送方向上移動,且接觸於搬送輥20之彈性構件50之上側外周(相較旋轉中心為上側),因此,可防止嵌入至搬送輥20之下側,從而可順利地進行 玻璃板G之搬送。 In addition, when the thickness of the glass sheet G is reduced (for example, the thickness is 0.4 mm or less), the rigidity of the glass sheet G is lowered, and therefore, the portion in contact with each of the strip-shaped guide members 70 is slightly deflected downward. It is carried. In addition, as shown in FIG. 2 (B) and (C) above, each of the strip-shaped guide members 70 is disposed so as to be bilaterally symmetrical in the axial direction of the transport roller 20, and the strip guide is disposed. Since the lead member 70 is wound in parallel with the conveyance direction of the glass sheet G (the rotation direction of the conveyance roller 20), a plurality of the guide members 70 are balanced so as to maintain the balance between the left and right directions of the glass sheet G (the direction orthogonal to the conveyance direction). The part rises up, so it does not fall much. In addition, since the front end portion G1 of the glass sheet G moves together with the belt-shaped guide member 70 in the conveyance direction and contacts the outer circumference of the upper side of the elastic member 50 of the conveyance roller 20 (the upper side is closer to the rotation center), , can be prevented from being embedded on the lower side of the conveying roller 20, so that smooth operation can be performed The glass plate G is transported.
再者,於各搬送輥20間未捲繞帶狀導引構件70之情形時,若玻璃板G之厚度較薄(例如厚度為0.4mm以下),則存在通過第一個搬送輥20之玻璃板G之前側端部G1於通過第2個搬送輥20時,在第2個搬送輥20之旋轉方向上被捲入,導致嵌入至第2個搬送輥20之下側而破損之虞。然而,根據本實施形態,由於捲繞於各搬送輥20間之各帶狀導引構件70一面支持玻璃板G一面在搬送方向上行進,因此,可防止玻璃板G之前側端部G1嵌入至搬送輥20之下側,並且亦可防止後側端部G2成為下垂之狀態而與搬送輥20接觸。 Further, when the strip-shaped guiding member 70 is not wound between the respective conveying rollers 20, if the thickness of the glass sheet G is thin (for example, the thickness is 0.4 mm or less), the glass passing through the first conveying roller 20 exists. When the front end portion G1 of the plate G passes through the second conveying roller 20, it is caught in the rotation direction of the second conveying roller 20, and is inserted into the lower side of the second conveying roller 20 to be broken. However, according to the present embodiment, since each of the strip-shaped guide members 70 wound between the respective conveyance rollers 20 travels in the conveyance direction while supporting the glass sheet G, it is possible to prevent the front end portion G1 of the glass sheet G from being fitted to the front end portion G1. The lower side of the conveyance roller 20 is also prevented from coming into contact with the conveyance roller 20 in a state where the rear end portion G2 is drooped.
再者,亦於玻璃板G之全長較長之情形,如圖3及圖4所示,玻璃板G之各端部G1及G2由各帶狀導引構件70導引地進行搬送,因此可順利地搬送。又,玻璃板G之厚度越薄,則各帶狀導引構件70之導引越可有效地發揮功能,並且無需調整各搬送輥20之間隔(搬送方向之相隔距離),便可順利地進行玻璃板G之搬送。 Further, in the case where the entire length of the glass sheet G is long, as shown in FIGS. 3 and 4, the end portions G1 and G2 of the glass sheet G are conveyed by the respective belt-shaped guiding members 70, so that Smoothly transported. Further, the thinner the thickness of the glass sheet G, the more effectively the function of guiding the strip-shaped guide members 70 can be, and the glass can be smoothly polished without adjusting the interval between the transport rollers 20 (the distance between the transport directions). Transfer of board G.
又,於上述實施形態中,對搬送平板用之玻璃板G之搬送路徑進行了說明,當然並不限於此,本發明亦可應用於玻璃板之生產線、或使用玻璃板之薄型機器(平板顯示器、觸控面板、LED(Light-Emitting Diode,發光二極體)照明、太陽電池、二次電池等)之生產線。 Moreover, in the above-described embodiment, the transport path of the glass plate G for transporting the flat plate has been described.
