Description
本發明係關於一種玻璃板之切斷裝置、玻璃板之切斷方法、及玻璃板之製造方法。 The invention relates to a cutting device for a glass plate, a cutting method for a glass plate, and a manufacturing method for a glass plate.
於專利文獻1、2等中，揭示有如下之玻璃板之切斷裝置，即，將於上表面加工有切斷線(亦稱為切割線、或劃線)之帶狀玻璃板(亦稱為玻璃帶)一面藉由輥式輸送機沿水平方向搬送，一面沿上述切斷線切斷。 Patent Documents 1, 2, and the like disclose a cutting device for a glass plate, that is, a strip-shaped glass plate (also referred to as a cutting line or a scribing line) having a cutting line (also called a cutting line or a scribing line) processed on the upper surface It is a glass ribbon) while being conveyed in a horizontal direction by a roller conveyor, and cut along the cutting line.
於專利文獻1之切斷裝置中，具備上推輥(以下稱為切斷用輥)作為切斷器件，於專利文獻2之切斷裝置中，具備大致三角柱狀之切割輥(以下稱為切斷用輥)作為切斷器件。使該等切斷用輥相對於帶狀玻璃板之下表面上升移動或旋轉，從而將帶狀玻璃板相對於搬送面而向上方頂起。藉此，於上述切斷線產生彎曲力矩，而將帶狀玻璃板沿切斷線切斷。 The cutting device of Patent Document 1 includes a push-up roller (hereinafter referred to as a cutting roller) as a cutting device, and the cutting device of Patent Document 2 includes a substantially triangular cylindrical cutting roller (hereinafter referred to as a cutting roller). Breaking roller) as a cutting device. These cutting rollers are moved up or rotated with respect to the lower surface of the strip-shaped glass plate, and the strip-shaped glass plate is pushed upward with respect to the conveyance surface. Thereby, a bending moment is generated at the cutting line, and the band-shaped glass plate is cut along the cutting line.
又，專利文獻1、2之切斷裝置係隔著切斷用輥而於帶狀玻璃板之搬送方向之上游側及下游側配置有按壓輥(按壓器件)。該等按壓輥抵接於帶狀玻璃板之上表面。由此，可藉由切斷用輥之切斷動作及按壓輥之按壓作用，而對切斷線之兩側施加相反方向之彎曲力矩，因此，帶狀玻璃板沿切斷線確實地被切斷。 Further, in the cutting devices of Patent Documents 1 and 2, pressing rollers (pressing means) are arranged on the upstream side and the downstream side of the belt glass plate in the conveying direction via the cutting roller. The pressing rollers abut on the upper surface of the glass strip. Therefore, a bending moment in the opposite direction can be applied to both sides of the cutting line by the cutting action of the cutting roller and the pressing action of the pressing roller. Therefore, the band-shaped glass plate is cut accurately along the cutting line. Off.
上述切斷裝置及切斷線加工裝置與利用浮式法等製造玻璃板之玻璃板製造裝置鄰接配置。即，對利用上述玻璃板製造裝置連續地製 造之緩冷後之帶狀玻璃板，一面於該狀態下進行搬送，一面利用上述切斷線加工裝置之切割器加工切斷線。切斷線之加工方向係相對於帶狀玻璃板之搬送方向正交之方向。於切斷線之加工之後，利用上述切斷裝置切斷帶狀玻璃板。藉此，可由帶狀玻璃板獲得特定尺寸之矩形狀玻璃板。 The cutting device and the cutting line processing device are disposed adjacent to a glass plate manufacturing device for manufacturing a glass plate by a float method or the like. That is, the glass plates are continuously manufactured by the glass plate manufacturing apparatus. The slowly-cooled ribbon-shaped glass plate is conveyed in this state while the cutting line is processed by a cutter of the cutting line processing device. The processing direction of the cutting line is a direction orthogonal to the conveying direction of the band-shaped glass plate. After the cutting line is processed, the band-shaped glass plate is cut by the cutting device. Thereby, a rectangular-shaped glass plate of a specific size can be obtained from the band-shaped glass plate.
再者，作為利用上述玻璃板製造裝置所製造之玻璃板，已知有用於建築用、汽車用等之厚度為數毫米(mm)以上之玻璃板、及用於要求較高之尺寸精度與形狀精度之FPD(Flat Panel Display，平板顯示器)等之厚度為0.7mm以下之玻璃板。又，亦已知有隨著所製造之帶狀玻璃板之厚度變薄，帶狀玻璃板之製造速度變快，而帶狀玻璃板之搬送速度變快。 Furthermore, as the glass plate manufactured by the above-mentioned glass plate manufacturing apparatus, a glass plate having a thickness of several millimeters (mm) or more for use in construction, automobiles, and the like is known, and is required for high dimensional accuracy and shape accuracy. FPD (Flat Panel Display, etc.) glass plates with a thickness of 0.7 mm or less. Furthermore, it is also known that as the thickness of the manufactured strip-shaped glass plate becomes thinner, the manufacturing speed of the strip-shaped glass plate becomes faster, and the transport speed of the strip-shaped glass plate becomes faster.

然而，於先前之玻璃板之切斷裝置中，存在剛被切斷後之帶狀玻璃板之前端緣部與配置於切斷用輥之下游側之按壓輥碰撞之問題。該問題之產生頻度隨著帶狀玻璃板之厚度變薄而變高，尤其是於厚度為0.5mm以下之帶狀玻璃板中明顯地產生。即，其原因在於，厚度為0.5mm以下之帶狀玻璃板易彎曲且搬送速度亦較快。 However, the conventional cutting device for glass plates has a problem in that the front edge of the strip-shaped glass plate immediately after cutting has collided with the pressing roller disposed on the downstream side of the cutting roller. The frequency of occurrence of this problem becomes higher as the thickness of the strip-shaped glass plate becomes thinner, especially in a strip-shaped glass plate having a thickness of 0.5 mm or less. That is, the reason is that a band-shaped glass plate having a thickness of 0.5 mm or less is easy to bend and the transfer speed is fast.
關於上述碰撞之問題，只要使下游側之按壓輥相對於切斷用輥，向下游側方向隔開能避免上述碰撞之距離之程度即可。然而，由於帶狀玻璃板具有越薄越易彎曲之性質，故而若下游側之按壓輥過度遠離切斷用輥，則切斷用輥之切斷動作之大半作為使帶狀玻璃板彎曲 之力而發揮作用。由此，無法對切斷線施加有效之彎曲力矩。 Regarding the above-mentioned collision, the pressing roller on the downstream side may be separated from the roller for cutting by a distance to the downstream side so as to avoid the above-mentioned collision. However, since the strip-shaped glass plate is thinner and easier to bend, if the pressing roller on the downstream side is too far away from the cutting roller, most of the cutting operation of the cutting roller is used to bend the strip-shaped glass plate. Force to work. Therefore, an effective bending moment cannot be applied to the cutting line.
亦即，為了將厚度為0.5mm以下之帶狀玻璃板沿切斷線順利地切斷，必須將下游側之按壓輥相對於切斷用輥近接配置，但於該情形時，會發生無法避免上述碰撞之問題的情況。 That is, in order to smoothly cut a strip-shaped glass plate having a thickness of 0.5 mm or less along the cutting line, it is necessary to arrange the pressing roller on the downstream side close to the cutting roller, but in this case, it will inevitably occur. Situation of the above collision problem.
又，厚度為0.5mm以下之帶狀玻璃板之前端緣部因自身重量而易彎曲，故而亦存在於利用輥式輸送機進行搬送中前端緣部與輥碰撞而被捲入至輥之下方之情況。 In addition, the front edge of the strip-shaped glass plate with a thickness of 0.5 mm or less is easily bent due to its own weight, so it also exists when the front edge and the roller collide with each other while being transported by the roller conveyor, and is wound under the roller. Happening.
本發明係鑒於此種情況而完成者，其目的在於提供一種即便為將配置於切斷器件之下游側之按壓器件相對於切斷器件近接配置之玻璃板之切斷裝置，亦可防止剛被切斷後之玻璃板之前端緣部與按壓器件碰撞之玻璃板之切斷裝置、玻璃板之切斷方法、及玻璃板之製造方法。 The present invention has been made in view of such a situation, and an object thereof is to provide a cutting device that can prevent a glass plate from being cut even if a pressing device disposed on the downstream side of the cutting device is disposed near the cutting device.

Moving means.
為了達成上述目的，本發明之一態樣提供一種玻璃板之切斷方 法，其特徵在於包括：搬送步驟，其藉由輥式輸送機將加工有切斷線之玻璃板自上游側向下游側沿水平方向進行搬送；切斷步驟，其藉由利用切斷器件將由上述輥式輸送機進行搬送中之上述玻璃板之下表面向上方頂起，而將上述玻璃板沿上述切斷線切斷；按壓步驟，其將配置於上述切斷器件之下游側之按壓器件抵接於上述玻璃板之上表面而將上述玻璃板之下表面按壓至上述輥式輸送機；以及按壓器件移動控制步驟，其於上述切斷器件之頂起動作結束時，使上述按壓器件自上述玻璃板之上表面退避移動，且於上述玻璃板之前端緣部通過上述按壓器件之下方之後，使上述按壓器件移動而返回到抵接於上述玻璃板之上表面之原來之位置。 In order to achieve the above object, one aspect of the present invention provides a cutting method of a glass plate. The method is characterized in that it includes a conveying step of conveying the glass plate processed with a cutting line in a horizontal direction from an upstream side to a downstream side by a roller conveyor; and a cutting step of using The roller conveyor lifts the lower surface of the glass plate upward during the conveyance, and cuts the glass plate along the cutting line; in the pressing step, the pressing device disposed on the downstream side of the cutting device Abutting the upper surface of the glass plate and pressing the lower surface of the glass plate to the roller conveyor; and a pressing device movement control step that causes the pressing device to automatically move from the pressing device when the lifting operation of the cutting device ends The upper surface of the glass plate moves backward, and after the front edge of the glass plate passes below the pressing device, the pressing device is moved to return to the original position abutting the upper surface of the glass plate.
根據本發明之一態樣，於搬送步驟中，藉由輥式輸送機搬送玻璃板，於切斷步驟中，藉由切斷器件將加工於玻璃板之切斷線之下方之下表面頂起，從而將玻璃板沿切斷線切斷。於該切斷時，由於在按壓步驟中，按壓器件抵接於玻璃板之上表面而將玻璃板之下表面按壓至輥式輸送機，故而玻璃板沿切斷線確實地被切斷。其後，於按壓器件移動控制步驟中，如下所述般藉由控制器件控制按壓器件之動作。即，於切斷器件之頂起動作結束時(包含即將結束之前及剛結束之後)，藉由被控制器件控制之驅動器件使按壓器件自玻璃板之上表面退避移動。按壓器件退避移動之位置較佳為玻璃板之上方，但亦可為玻璃板之側方。藉此，即便為將配置於切斷器件之下游側之按壓器件相對於切斷器件近接配置之玻璃板之切斷裝置，亦可防止剛被切斷後之玻璃板之前端緣部與按壓器件碰撞。而且，於玻璃板之前端緣部通過按壓器件之下方之後，藉由被控制器件控制之驅動器件使按壓器件移動而返回到抵接於玻璃板之上表面之原來之位置。藉此，可沿下一條切斷線切斷玻璃板。 According to an aspect of the present invention, in the conveying step, the glass plate is conveyed by a roller conveyor, and in the cutting step, the lower surface processed below the cutting line of the glass plate is ejected by the cutting device. , So that the glass plate is cut along the cutting line. At the time of this cutting, since the pressing device abuts the upper surface of the glass plate and presses the lower surface of the glass plate to the roller conveyor in the pressing step, the glass plate is surely cut along the cutting line. Thereafter, in the pressing device movement control step, the operation of the pressing device is controlled by the control device as described below. That is, at the end of the jacking operation of the cutting device (including immediately before the end and immediately after the end), the driving device controlled by the control device causes the pressing device to retreat from the upper surface of the glass plate. The position where the pressing device moves back and forth is preferably above the glass plate, but it can also be the side of the glass plate. With this, even if the cutting device is a glass plate in which the pressing device disposed on the downstream side of the cutting device is closely adjacent to the cutting device, it is possible to prevent the front edge of the glass plate immediately after being cut from colliding with the pressing device . In addition, after the front edge of the glass plate passes below the pressing device, the driving device controlled by the control device moves the pressing device and returns to the original position abutting the upper surface of the glass plate. Thereby, the glass plate can be cut along the next cutting line.

於自使用浮式法及下拉法等製造方法之玻璃板製造裝置連續地搬送玻璃板，並切斷該玻璃板之切斷裝置之情形時，隨著玻璃板之厚度變薄玻璃板變得易彎曲，且搬送速度亦變快。由此，可將本發明之一態樣之切斷裝置有效地應用於厚度為0.5mm以下之玻璃板。 When a glass plate is continuously conveyed from a glass plate manufacturing device using a manufacturing method such as a float method and a down-draw method, and the glass plate is cut by a cutting device, the glass plate becomes easier as the thickness of the glass plate becomes thinner. Bends and speeds up. Therefore, the cutting device according to an aspect of the present invention can be effectively applied to a glass plate having a thickness of 0.5 mm or less.
本發明之一態樣較佳為，上述按壓器件抵接於上述玻璃板之上表面之緣部。 In one aspect of the present invention, it is preferable that the pressing device abuts an edge portion of an upper surface of the glass plate.
根據本發明之一態樣，由於按壓器件不抵接於玻璃板之製品面，故而可保護製品面免受按壓器件影響。 According to one aspect of the present invention, since the pressing device does not abut the product surface of the glass plate, the product surface can be protected from being affected by the pressing device.

如圖2般於切斷裝置10中，具備將於上表面加工有切斷線14之帶狀玻璃板12沿切斷線14進行切斷之圓筒形狀之切斷用輥(切斷器件：升降構件)16。又，於切斷用輥16之帶狀玻璃板12之搬送方向之上游側，具備包含複數根圓筒形狀之輥18之輥式輸送機20。帶狀玻璃板12係藉由輥式輸送機20而沿水平方向、且沿箭頭A所示之搬送方向被搬送。進而，於切斷用輥16之上述搬送方向之下游側，具備包含複數根圓筒形狀之輥22之輥式輸送機24。 As shown in FIG. 2, the cutting device 10 is provided with a cutting roller (cutting device: cylindrical shape) that cuts a strip-shaped glass plate 12 with a cutting line 14 on its upper surface and cuts along the cutting line 14. Lifting member) 16. Further, a roller conveyor 20 including a plurality of cylindrical rollers 18 is provided on the upstream side in the conveying direction of the belt-shaped glass plate 12 of the cutting roller 16. The belt-shaped glass plate 12 is transported in a horizontal direction and in a transport direction indicated by an arrow A by a roller conveyor 20. Further, a roller conveyor 24 including a plurality of cylindrical rollers 22 is provided on the downstream side of the cutting roller 16 in the conveying direction.
再者，該等輥18、22係以上表面水平高度成為相同之高度之方式設置，但亦可以朝向下游側高度變高之方式設置。又，切斷用輥16之直徑大於輥18、22之直徑，但亦可將切斷用輥16之直徑設為小於輥18、22之直徑。 In addition, the rollers 18 and 22 are installed so that the horizontal heights of the above surfaces become the same height, but they may also be installed such that the height becomes higher toward the downstream side. The diameter of the cutting roller 16 is larger than the diameters of the rollers 18 and 22. However, the diameter of the cutting roller 16 may be smaller than the diameters of the rollers 18 and 22.
此外，為了易於切斷帶狀玻璃板12，可於切斷用輥16之上述搬送方向之上游側配置按壓輥26，於上述搬送方向之下游側配置按壓輥(按壓器件)28。按壓輥26、28係相同形狀之輥，且設置於相對於切斷用輥16對稱之位置。 Further, in order to easily cut the strip-shaped glass plate 12, a pressing roller 26 may be disposed upstream of the cutting roller 16 in the conveying direction, and a pressing roller (pressing device) 28 may be disposed downstream of the conveying direction. The pressing rollers 26 and 28 are rollers of the same shape and are provided at positions symmetrical to the cutting roller 16.
按壓輥26抵接於帶狀玻璃板12之上表面，藉此，帶狀玻璃板12之下表面被按壓至輥式輸送機20之輥18。又，按壓輥28抵接於即將切 斷之前之帶狀玻璃板12之上表面，從而將該帶狀玻璃板12之下表面按壓至輥式輸送機24之輥22。再者，按壓輥28亦抵接於剛切斷後之矩形狀玻璃板30之上表面，藉此將矩形狀玻璃板30按壓至輥式輸送機24之輥22。 The pressing roller 26 is in contact with the upper surface of the belt-shaped glass plate 12, whereby the lower surface of the belt-shaped glass plate 12 is pressed against the roller 18 of the roller conveyor 20. In addition, the pressing roller 28 abuts on the The upper surface of the band-shaped glass plate 12 before being cut off, so that the lower surface of the band-shaped glass plate 12 is pressed against the roller 22 of the roller conveyor 24. Furthermore, the pressing roller 28 is also in contact with the upper surface of the rectangular glass plate 30 immediately after cutting, thereby pressing the rectangular glass plate 30 to the roller 22 of the roller conveyor 24.
於圖1中，為了明確地表示切斷用輥16之配置位置而省略了輥式輸送機20、24。又，如圖1般按壓輥26、28係沿相對於帶狀玻璃板12之搬送方向正交之方向而配置，且構成為可抵接於帶狀玻璃板12之寬度全域、及矩形狀玻璃板30之寬度全域之長度。按壓輥26、28及切斷用輥16之材質並無特別限定，可使用不會損傷帶狀玻璃板12及矩形狀玻璃板30之材質者。加工於帶狀玻璃板12之上表面之切斷線14之加工方向係與上述搬送方向正交之方向。 In FIG. 1, the roller conveyors 20 and 24 are omitted in order to clearly show the arrangement position of the cutting roller 16. In addition, as shown in FIG. 1, the pressing rollers 26 and 28 are arranged in a direction orthogonal to the conveyance direction of the strip-shaped glass plate 12 and are configured to abut the entire width of the strip-shaped glass plate 12 and the rectangular glass The width of the plate 30 is the entire length. The materials of the pressing rollers 26 and 28 and the cutting roller 16 are not particularly limited, and materials that do not damage the band-shaped glass plate 12 and the rectangular glass plate 30 can be used. The processing direction of the cutting line 14 processed on the upper surface of the band-shaped glass plate 12 is a direction orthogonal to the above-mentioned conveyance direction.
又，若如圖2般自帶狀玻璃板12將矩形狀玻璃板30切離，則輥式輸送機24之輥22之圓周速率係以相對於輥式輸送機20之輥18之圓周速率進行特定時間加速之方式被控制。藉此，被連續地切離之複數個矩形狀玻璃板30係於被隔開特定之間隔之狀態下向輥式輸送機24之下游側之取板部(未圖示)搬送。藉此，可防止因與鄰接之矩形狀玻璃板30之接觸所導致之破損。 In addition, if the rectangular glass plate 30 is cut away from the band-shaped glass plate 12 as shown in FIG. 2, the peripheral speed of the roller 22 of the roller conveyor 24 is performed relative to the peripheral speed of the roller 18 of the roller conveyor 20. The way to accelerate at a specific time is controlled. As a result, the plurality of rectangular glass plates 30 that are continuously cut away are conveyed to a plate-receiving portion (not shown) on the downstream side of the roller conveyor 24 in a state of being separated by a specific interval. This can prevent damage due to contact with the adjacent rectangular glass plate 30.
<關於切斷用輥16與按壓輥28之升降控制> <About Lifting Control of Cutting Roller 16 and Pressing Roller 28>
於切斷裝置10中包括：伺服馬達32，其使切斷用輥16升降移動；及驅動部(驅動器件)34，其使按壓輥28相對於帶狀玻璃板12之上表面於上下方向進退移動。又，於切斷裝置10中包括伺服馬達32、及控制驅動部34之控制部(控制器件：Controller)36。 The cutting device 10 includes a servo motor 32 that moves the cutting roller 16 up and down, and a drive unit (driving device) 34 that advances and retracts the pressing roller 28 with respect to the upper surface of the band-shaped glass plate 12 in the vertical direction. mobile. The cutting device 10 includes a servo motor 32 and a control unit (controller: Controller) 36 that controls the drive unit 34.
驅動部34具備電磁閥及速度控制器，藉由控制部36控制利用上述電磁閥進行之流體(空氣)之供給及停止，藉此，可控制使按壓輥28升降之驅動機構40之升降ON(開始)/OFF(停止)。又，藉由控制部36控制利用上述速度控制器所控制之流體之流量，藉此，可控制驅動機構 40之升降速度。再者，作為驅動部34，亦可使用伺服馬達。 The drive unit 34 includes a solenoid valve and a speed controller. The control unit 36 controls the supply and stop of the fluid (air) using the solenoid valve, thereby controlling the lift ON of the drive mechanism 40 that raises and lowers the pressing roller 28 ( (Start) / OFF (Stop). In addition, the control unit 36 controls the flow rate of the fluid controlled by the speed controller, thereby controlling the driving mechanism. Lifting speed of 40. A servo motor may be used as the driving unit 34.
伺服馬達32、驅動部34係按照自控制部36輸出之動作指令(例如特定頻率之脈波串)而被驅動。伺服馬達32係經由滾珠螺桿裝置等公知之驅動機構38而連結於切斷用輥16，並按照來自控制部36之動作指令而旋轉，且該旋轉運動藉由驅動機構38被轉換為直線運動。藉此，切斷用輥16進行升降移動。切斷用輥16之通常位置係如圖2之二點鏈線所示般被設定為切斷用輥16之上表面水平高度與輥18之上表面水平高度位於相同高度之位置。藉由使切斷用輥16自通常位置上升至圖2之實線所示之上升位置，而將帶狀玻璃板12之下表面向上方頂起。又，切斷用輥16按照自控制部36輸出之動作指令，自上升位置直接下降移動而恢復至通常位置。 The servo motor 32 and the drive unit 34 are driven in accordance with an operation command (for example, a pulse train of a specific frequency) output from the control unit 36. The servo motor 32 is connected to the cutting roller 16 via a known driving mechanism 38 such as a ball screw device, and rotates in accordance with an operation command from the control unit 36, and the rotational motion is converted into a linear motion by the driving mechanism 38. Thereby, the cutting roller 16 moves up and down. The normal position of the cutting roller 16 is set so that the horizontal height of the upper surface of the cutting roller 16 and the horizontal height of the upper surface of the roller 18 are at the same height as shown by the two-dot chain line in FIG. 2. By raising the cutting roller 16 from the normal position to the raised position shown by the solid line in FIG. 2, the lower surface of the band-shaped glass plate 12 is pushed upward. In addition, the cutting roller 16 moves downward from the raised position and returns to the normal position in accordance with an operation command output from the control unit 36.
驅動部34亦同樣地，經由公知之驅動機構40而連結於按壓輥28，且按照來自控制部36之動作指令而被驅動，藉此，按壓輥28進行升降移動。按壓輥28之通常位置係如圖2之實線所示般，被設定為抵接於帶狀玻璃板12之上表面之位置。按壓輥28係藉由自通常位置上升至圖2之二點鏈線所示之上升位置，而相對於帶狀玻璃板12之上表面向上方退避移動。又，按壓輥28按照自控制部36輸出之動作指令，自上升位置直接下降移動而恢復至通常位置。 Similarly, the driving unit 34 is connected to the pressing roller 28 via a known driving mechanism 40 and is driven in accordance with an operation command from the control unit 36, whereby the pressing roller 28 moves up and down. The normal position of the pressing roller 28 is set to a position in contact with the upper surface of the band-shaped glass plate 12 as shown by the solid line in FIG. 2. The pressing roller 28 is moved upward from the upper surface of the band-shaped glass plate 12 by rising from the normal position to the raised position shown by the two-point chain line in FIG. 2. In addition, the pressing roller 28 directly descends from the raised position and returns to the normal position in accordance with an operation command output from the control unit 36.
自控制部36輸出至伺服馬達32之切斷用輥16之上升開始之動作指令、及按壓輥28之上升開始之動作指令係基於明確地掌握切斷用輥16與切斷線14之位置關係之方法、例如來自一面接觸於帶狀玻璃板12一面對帶狀玻璃板12之搬送量進行測量之眾所周知之測量裝置42之輸出信號而被輸出。又，按壓輥28之上升開始之動作指令係於切斷用輥16之頂起動作結束時(包含即將結束之前及剛結束之後)被輸出。藉此，帶狀玻璃板12係藉由切斷用輥16之切斷動作即上升動作與按壓輥28之按壓作用而沿切斷線14確實地被切斷。 The operation command for starting the rising of the cutting roller 16 output from the control unit 36 to the servo motor 32 and the operation command for starting the rising of the pressing roller 28 are based on a clear understanding of the positional relationship between the cutting roller 16 and the cutting line 14 For example, an output signal from a well-known measuring device 42 that measures the conveyance of the belt-shaped glass plate 12 while contacting the belt-shaped glass plate 12 is output. The operation command for starting the pressing of the pressing roller 28 is output when the lifting operation of the cutting roller 16 is completed (including immediately before and immediately after completion). Accordingly, the band-shaped glass plate 12 is reliably cut along the cutting line 14 by the cutting operation of the cutting roller 16, that is, the raising operation and the pressing action of the pressing roller 28.
再者，作為按壓輥28之上升開始之動作控制方法，亦可以相對於切斷用輥16之上升開始時，延遲特定時間而開始上升之方式對驅動部34進行時間控制。又，亦可使用氣缸等驅動器件代替伺服馬達32，但若使用伺服馬達32，則可精細地控制上升開始動作，故而適於厚度較薄之帶狀玻璃板12之切斷。 In addition, as an operation control method for the start of the rising of the pressing roller 28, the driving unit 34 may be time-controlled so as to delay the start of the rising of the cutting roller 16 by a specific time. In addition, a driving device such as an air cylinder may be used instead of the servo motor 32. However, if the servo motor 32 is used, the start-up operation can be finely controlled, and therefore it is suitable for cutting the thin glass plate 12 having a thin thickness.
[切斷裝置10之作用] [Function of the cutting device 10]
圖3(A)~(E)係按時間序列表示切斷用輥16之升降動作及按壓輥28之升降動作之說明圖。再者，圖3所示之箭頭B表示輥18之旋轉方向，箭頭C表示按壓輥26之旋轉方向，箭頭D表示切斷用輥16之旋轉方向，箭頭E表示輥22之旋轉方向，箭頭F表示按壓輥28之旋轉方向。又，箭頭G表示切斷用輥16之升降之移動方向，箭頭H表示按壓輥28之升降之移動方向。 FIGS. 3 (A) to 3 (E) are explanatory diagrams showing the lifting operation of the cutting roller 16 and the pressing operation of the pressing roller 28 in a time series. In addition, the arrow B shown in FIG. 3 indicates the rotation direction of the roller 18, the arrow C indicates the rotation direction of the pressing roller 26, the arrow D indicates the rotation direction of the cutting roller 16, the arrow E indicates the rotation direction of the roller 22, and the arrow F The rotation direction of the pressing roller 28 is shown. The arrow G indicates the moving direction of the lifting roller 16 for lifting, and the arrow H indicates the moving direction of the pressing roller 28 for lifting.
如圖3(A)所示般，藉由輥式輸送機20搬送帶狀玻璃板12(搬送步驟)，當切斷線14逐漸接近切斷用輥16之上方時，基於來自控制部36之動作信號而驅動伺服馬達32(參照圖1、圖2)，從而如箭頭G般開始切斷用輥16之上升移動。 As shown in FIG. 3 (A), when the belt-shaped glass plate 12 is conveyed by the roller conveyor 20 (conveying step), when the cutting line 14 approaches the cutting roller 16 gradually, The servo motor 32 (see FIGS. 1 and 2) is driven by the operation signal, and the upward movement of the cutting roller 16 is started like an arrow G.
然後，如圖3(B)所示般，藉由切斷用輥16之箭頭G所示之上升移動，帶狀玻璃板12之切斷線14之下方之下表面被逐漸頂起。 Then, as shown in FIG. 3 (B), by the upward movement shown by the arrow G of the cutting roller 16, the lower surface below the cutting line 14 of the band-shaped glass plate 12 is gradually raised.
然後，如圖3(C)所示般，於切斷用輥16上升至上升位置時，帶狀玻璃板12沿切斷線14被切斷(切斷步驟)。 Then, as shown in FIG. 3 (C), when the cutting roller 16 is raised to the raised position, the band-shaped glass plate 12 is cut along the cutting line 14 (cutting step).
於圖3(A)~(C)所示之帶狀玻璃板12之切斷時，按壓輥28位於通常位置，抵接於帶狀玻璃板12之上表面而將帶狀玻璃板12之下表面按壓至輥式輸送機24之輥22(按壓步驟)。藉此，帶狀玻璃板12如圖3(C)般沿切斷線14確實地被切斷。 When the band-shaped glass plate 12 shown in FIGS. 3 (A) to (C) is cut, the pressing roller 28 is located at a normal position, and abuts against the upper surface of the band-shaped glass plate 12 and places the band-shaped glass plate 12 below. The surface is pressed against the roller 22 of the roller conveyor 24 (pressing step). Thereby, the band-shaped glass plate 12 is cut | disconnected reliably along the cutting line 14 like FIG.3 (C).
其後，按壓輥28係藉由控制部36如以下般被控制動作(按壓器件移動控制步驟)。 Thereafter, the control roller 36 is controlled to operate as described below by the control unit 36 (pressing device movement control step).
首先，按壓輥28係於圖3(C)所示之切斷用輥16之頂起動作結束時(包含即將結束之前及剛結束之後)，藉由被控制部36控制之驅動部34而如箭頭H般自帶狀玻璃板12之上表面退避移動，從而上升至圖3(D)所示之上升位置。 First, the pressing roller 28 is driven by the driving unit 34 controlled by the control unit 36 when the lifting operation of the cutting roller 16 shown in FIG. 3 (C) is completed (including immediately before and immediately after the end). The arrow H retreats from the upper surface of the band-shaped glass plate 12 and rises to the raised position shown in FIG. 3 (D).
藉此，如圖3(D)般，帶狀玻璃板12之前端緣部12A不與按壓輥26碰撞，而因自身重量向輥22逐漸下落。 Thereby, as shown in FIG.3 (D), the front edge part 12A of the strip-shaped glass plate 12 does not collide with the pressing roller 26, but falls to the roller 22 gradually by its own weight.
因此，根據實施形態之切斷裝置10，即便將按壓輥28相對於切斷用輥16近接配置，亦可防止剛被切斷後之帶狀玻璃板12之前端緣部12A與按壓輥28碰撞。 Therefore, according to the cutting device 10 according to the embodiment, even if the pressing roller 28 is disposed close to the cutting roller 16, it is possible to prevent the front edge portion 12A of the band-shaped glass plate 12 immediately after the cutting from colliding with the pressing roller 28.
其後，按壓輥28於帶狀玻璃板12之前端緣部12A通過按壓輥28之下方之後，藉由被控制部36控制之驅動部34而如圖3(E)般移動而返回到抵接於帶狀玻璃板12之上表面之原來之通常位置。藉此，可沿下一條切斷線14切斷帶狀玻璃板12。 Thereafter, after the pressing roller 28 passes under the pressing roller 28 before the front edge portion 12A of the strip-shaped glass plate 12, it is moved by the driving portion 34 controlled by the control portion 36 as shown in FIG. 3 (E) and returns to the abutment. The original normal position on the upper surface of the band-shaped glass plate 12. Thereby, the strip-shaped glass plate 12 can be cut along the next cutting line 14.
再者，按壓輥28退避移動之位置較佳為如圖3(D)般之帶狀玻璃板12之上方，但亦可為帶狀玻璃板12之側方。又，切斷用輥16係自圖3(C)所示之上方位置沿箭頭G方向下降移動而恢復至圖3(E)所示之通常位置。 In addition, the position where the pressing roller 28 moves back and forth is preferably above the band-shaped glass plate 12 as shown in FIG. 3 (D), but may be the side of the band-shaped glass plate 12. The cutting roller 16 moves downward from the upper position shown in FIG. 3 (C) in the direction of the arrow G and returns to the normal position shown in FIG. 3 (E).
<關於輥18(22)間等之間隙之大小之設定> <Setting the size of the gap between rollers 18 (22) and so on>
厚度為0.5mm以下(更佳為0.3mm以下)之帶狀玻璃板12之前端緣部12A因自身重量而易彎曲，故而存在於利用輥式輸送機20(24)進行搬送中前端緣部12A與輥18(22)之表面碰撞而被捲入至輥18(22)之下方之情況。 The front edge portion 12A of the strip-shaped glass plate 12 having a thickness of 0.5 mm or less (more preferably 0.3 mm or less) is easily bent due to its own weight, and therefore exists in the front edge portion 12A during transportation by the roller conveyor 20 (24) In the case of colliding with the surface of the roller 18 (22) and being drawn under the roller 18 (22).
設定用以防止上述不良情況之輥18(22)間之間隙之大小。 The size of the gap between the rollers 18 (22) to prevent the above-mentioned problems is set.
圖4係用以說明輥18(22)間之較佳之間隙之大小之主要部分放大側視圖。 Fig. 4 is an enlarged side view of a main part for explaining the size of a preferable gap between the rollers 18 (22).
根據圖4，較佳於將利用輥式輸送機20(24)進行搬送中之帶狀玻 璃板12(包含矩形狀玻璃板30)之前端緣部12A(30A)接觸於輥式輸送機20(24)之輥18(22)時之接觸點距輥18(22)之頂點P之高度設為K，將輥18(22)之半徑設為R，將輥18(22)間之間隙之大小(最短距離)設為G時，將G設定為滿足K<R。 According to FIG. 4, it is preferable to use a belt-shaped glass to be conveyed by a roller conveyor 20 (24). Height of the contact point when the front edge 12A (30A) of the glass plate 12 (including the rectangular glass plate 30) contacts the roller 18 (22) of the roller conveyor 20 (24) from the vertex P of the roller 18 (22) When K is set, the radius of the roller 18 (22) is set to R, and when the size (shortest distance) of the gap between the rollers 18 (22) is set to G, G is set to satisfy K <R.
藉由如上述般設定G，即便於在利用輥式輸送機20(24)進行搬送中帶狀玻璃板12(30)之前端緣部12A(30A)因自身重量而向下方彎曲而使前端緣部12A(30A)與輥18(22)之表面碰撞之情形時，亦可防止前端緣部12A(30A)被捲入至輥18(22)之下方。 By setting G as described above, even before the belt glass plate 12 (30) is being conveyed by the roller conveyor 20 (24), the end edge portion 12A (30A) is bent downward due to its own weight, so that the front edge is bent. When the portion 12A (30A) collides with the surface of the roller 18 (22), the leading edge portion 12A (30A) can be prevented from being caught under the roller 18 (22).
再者，滿足K<R之G亦適合於圖3中輥18與切斷用輥16之間之間隙、及切斷用輥16與輥22之間之間隙。又，於圖3中係切斷用輥16始終接觸於帶狀玻璃板12之下表面之形態，但亦可為除了切斷時以外切斷用輥16不接觸於帶狀玻璃板12之下表面之形態、即切斷用輥16退避至帶狀玻璃板12之下方之形態。於該形態中，輥18與輥22之間之G被設定為滿足K<R之值。再者，於下述之圖6之形態中亦同樣地設定G。 Furthermore, G satisfying K <R is also suitable for the gap between the roller 18 and the cutting roller 16 and the gap between the cutting roller 16 and the roller 22 in FIG. 3. In FIG. 3, the cutting roller 16 is always in contact with the lower surface of the strip-shaped glass plate 12, but the cutting roller 16 may not be in contact with the strip-shaped glass plate 12 except when cutting. The shape of the surface, that is, the shape in which the cutting roller 16 is retracted below the band-shaped glass plate 12. In this form, G between the rollers 18 and 22 is set to a value satisfying K <R. It should be noted that G is set in the same manner in the form of FIG. 6 described below.
<關於帶狀玻璃板12之厚度> <About the thickness of the strip-shaped glass plate 12>
又，如上所述，實施形態之切斷裝置10之切斷對象之玻璃板之厚度較佳為0.5mm以下，更佳為0.3mm以下。又，其厚度較佳為0.05mm以上。 As described above, the thickness of the glass plate to be cut by the cutting device 10 of the embodiment is preferably 0.5 mm or less, and more preferably 0.3 mm or less. The thickness is preferably 0.05 mm or more.
於自使用浮式法及下拉法等製法之玻璃板製造裝置連續地搬送帶狀玻璃板，並將該帶狀玻璃板切斷之切斷裝置之情形時，隨著帶狀玻璃板之厚度變薄，帶狀玻璃板變得易彎曲，且搬送速度亦變快。由此，可將實施形態之切斷裝置10有效地應用於厚度為0.5mm以下之帶狀玻璃板12。再者，實施形態之切斷裝置10亦可有效地應用於厚度為0.3mm以下之帶狀玻璃板12。 In the case of a continuous glass belt manufacturing device that uses a glass plate manufacturing apparatus such as a float method and a pull-down method and cuts the belt glass plate, the thickness of the belt glass plate changes. Thin, ribbon-shaped glass plate becomes easy to bend, and the conveying speed also becomes faster. Accordingly, the cutting device 10 according to the embodiment can be effectively applied to a band-shaped glass plate 12 having a thickness of 0.5 mm or less. The cutting device 10 according to the embodiment can be effectively applied to a band-shaped glass plate 12 having a thickness of 0.3 mm or less.
<關於按壓輥之另一形態> <About another form of a pressing roller>
圖5(A)、(B)係表示按壓輥相對於帶狀玻璃板之較佳之抵接位置之平面圖。 5 (A) and 5 (B) are plan views showing preferred contact positions of the pressing rollers with respect to the band-shaped glass plate.
於圖5(A)中，表示邊料被事先切斷之帶狀玻璃板12，於圖5(B)中，表示具有邊料13A之帶狀玻璃板13。又，圖5(A)、(B)所示之二點鏈線L之內側之區域(玻璃板之上表面中之成為製品面之中央之面)為製品玻璃板15。又，所謂邊料13A係指於帶狀玻璃板13之製造時於帶狀玻璃板13之兩緣部沿搬送方向形成之玻璃板，且為厚度較製品玻璃板15厚之玻璃板。 FIG. 5 (A) shows a strip-shaped glass plate 12 in which the side material is cut in advance, and FIG. 5 (B) shows a strip-shaped glass plate 13 having a side material 13A. The area inside the two-dot chain line L (the surface on the upper surface of the glass plate that becomes the center of the product surface) shown in FIGS. 5A and 5B is the product glass plate 15. The edge material 13A refers to a glass plate that is formed along the conveying direction at both edges of the strip-shaped glass plate 13 when the strip-shaped glass plate 13 is manufactured, and is a glass plate that is thicker than the product glass plate 15.
於圖5(A)中，按壓輥28A抵接於除了製品玻璃板15以外之製品玻璃板15之外側區域之玻璃板17，於圖5(B)中，按壓輥28B抵接於邊料13A。 In FIG. 5 (A), the pressing roller 28A is in contact with the glass plate 17 in the area outside the product glass plate 15 other than the product glass plate 15. In FIG. 5 (B), the pressing roller 28B is in contact with the side material 13A. .
藉由如此使按壓輥28A、28B抵接於製品玻璃板15之外側，可保護製品玻璃板15之上表面之品質區域不受按壓輥28A、28B影響。又，對於按壓輥26亦同樣。上述所謂品質區域係指作為FPD用玻璃板被要求嚴格之品質之區域。藉由使按壓輥28A、28B抵接於品質區域之外側，可防止因按壓輥28A、28B之抵接所導致之品質區域之表面缺損。 By making the pressing rollers 28A and 28B abut on the outer side of the product glass plate 15 in this way, the quality region of the upper surface of the product glass plate 15 can be protected from the pressing rollers 28A and 28B. The same applies to the pressing roller 26. The above-mentioned quality region refers to a region where strict quality is required as a glass plate for FPD. By abutting the pressing rollers 28A and 28B on the outside of the quality region, it is possible to prevent surface defects in the quality region caused by the abutment of the pressing rollers 28A and 28B.
<關於切斷器件之另一形態> <About another aspect of a cutting device>
於圖6(A)~(E)中，表示作為另一切斷器件之切斷用旋轉輥(旋轉輥)44。又，於圖6(A)~(E)中，按時間序列表示切斷用旋轉輥44與按壓輥28之升降動作。進而，箭頭J表示切斷用旋轉輥44之旋轉方向，其他箭頭A、B、C、E、F、H所示之方向與圖3之箭頭A、B、C、E、F、H所示之方向相同。 In FIGS. 6 (A) to (E), a rotating roller (rotating roller) 44 for cutting which is another cutting device is shown. In addition, in FIGS. 6 (A) to (E), the raising and lowering operations of the cutting rotary roller 44 and the pressing roller 28 are shown in time series. Further, the arrow J indicates the direction of rotation of the cutting rotation roller 44. The directions shown by other arrows A, B, C, E, F, and H are shown by arrows A, B, C, E, F, and H in FIG. 3. The directions are the same.
於切斷用旋轉輥44之表面(周面)具備：第1突起46，其於旋轉方向上游側將帶狀玻璃板12之下表面向上方頂起；及第2突起48，其於第1突起46之旋轉方向下游側與第1突起46鄰接而配置。 The surface (peripheral surface) of the cutting rotation roller 44 is provided with a first projection 46 which pushes the lower surface of the glass strip 12 upward on the upstream side in the rotation direction, and a second projection 48 which is formed on the first The downstream side of the protrusion 46 in the rotation direction is arranged adjacent to the first protrusion 46.
如圖6(A)所示般，藉由輥式輸送機20搬送帶狀玻璃板12，當切斷線14逐漸接近切斷用旋轉輥44之上方時，如箭頭J般開始切斷用旋轉輥44之旋轉。 As shown in FIG. 6 (A), the belt-shaped glass plate 12 is transported by the roller conveyor 20, and when the cutting line 14 gradually approaches the cutting rotary roller 44, the cutting rotation starts as indicated by the arrow J The rotation of the roller 44.
然後，如圖6(B)所示般，藉由切斷用旋轉輥44之箭頭J所示之旋轉，帶狀玻璃板12之切斷線14之下方之下表面被第1突起46逐漸頂起。 Then, as shown in FIG. 6 (B), by the rotation indicated by the arrow J of the cutting rotation roller 44, the lower surface below the cutting line 14 of the band-shaped glass plate 12 is gradually pushed by the first protrusion 46. Up.
然後，如圖6(C)所示般，於第1突起46朝向上方之位置，帶狀玻璃板12沿切斷線14被切斷。 Then, as shown in FIG. 6 (C), at a position where the first protrusion 46 faces upward, the band-shaped glass plate 12 is cut along the cutting line 14.
於圖6(A)~(C)所示之帶狀玻璃板12之切斷時，按壓輥28位於通常位置，抵接於帶狀玻璃板12之上表面而將帶狀玻璃板12之下表面按壓至輥式輸送機24之輥22。藉此，帶狀玻璃板12如圖6(C)般沿切斷線14確實地被切斷。 When the strip-shaped glass plate 12 shown in FIGS. 6 (A) to (C) is cut, the pressing roller 28 is located at a normal position, and abuts against the upper surface of the strip-shaped glass plate 12 and lowers the strip-shaped glass plate 12 The surface is pressed against the roller 22 of the roller conveyor 24. Thereby, the band-shaped glass plate 12 is cut | disconnected reliably along the cutting line 14 like FIG.6 (C).
其後，按壓輥28於圖6(C)所示之第1突起46之頂起動作之結束時(包含即將結束之前或流量直後之後)，藉由被控制部36(參照圖1、圖2)控制之驅動部34，如箭頭H般自帶狀玻璃板12之上表面退避移動，而上升至圖6(D)所示之上升位置。 Thereafter, at the end of the pushing-up operation of the first protrusion 46 shown in FIG. 6 (C) (including immediately before the end or immediately after the flow rate is straightened), the control unit 36 (see FIG. 1 and FIG. 2) The driving portion 34 controlled by the) moves backward from the upper surface of the band-shaped glass plate 12 like the arrow H, and rises to the raised position shown in FIG. 6 (D).
藉此，如圖6(D)般，帶狀玻璃板12之前端緣部12A不與按壓輥26碰撞，而因自身重量向輥22逐漸下落。 As a result, as shown in FIG. 6 (D), the front edge portion 12A of the band-shaped glass plate 12 does not collide with the pressing roller 26, but gradually falls toward the roller 22 due to its own weight.
因此，根據實施形態之切斷裝置10，即便將按壓輥28相對於切斷用旋轉輥44而近接配置，亦可防止剛被切斷後之帶狀玻璃板12之前端緣部12A與按壓輥28碰撞。 Therefore, according to the cutting device 10 of the embodiment, even if the pressing roller 28 is disposed close to the cutting rotation roller 44, the front edge portion 12A of the band-shaped glass plate 12 immediately after the cutting and the pressing roller 28 can be prevented. collision.
其後，按壓輥28於帶狀玻璃板12之前端緣部12A通過按壓輥28之下方之後，藉由被控制部36控制之驅動部34而如圖6(E)般移動而返回到抵接於帶狀玻璃板12之上表面之原來之通常位置。藉此，可沿下一條切斷線14切斷帶狀玻璃板12。 Thereafter, after the pressing roller 28 passes under the pressing roller 28 before the front edge portion 12A of the band-shaped glass plate 12, it is moved by the driving portion 34 controlled by the control portion 36 as shown in FIG. 6 (E) and returns to the abutment. The original normal position on the upper surface of the band-shaped glass plate 12. Thereby, the strip-shaped glass plate 12 can be cut along the next cutting line 14.
另一方面，根據切斷用旋轉輥44，若如圖6(C)般將帶狀玻璃板12 沿切斷線14切斷，則帶狀玻璃板12之前端緣部12A係如圖6(D)般接觸於第2突起48，而不會下落至切斷用旋轉輥44之輥表面而通過切斷用旋轉輥44。藉此，可防止因前端緣部12A下落至上述輥表面而引起之前端緣部12A之破損。於該情形時，可藉由利用伺服馬達驅動切斷用旋轉輥44，而實施精度較高之切斷。 On the other hand, when the rotating glass 44 for cutting is used, as shown in FIG. When cutting along the cutting line 14, the front edge portion 12A of the strip-shaped glass plate 12 contacts the second protrusion 48 as shown in FIG. 6 (D), and does not fall to the roller surface of the cutting rotary roller 44 and passes through it. Cutting rotation roller 44. This prevents the front edge portion 12A from being damaged due to the front edge portion 12A falling to the roller surface. In this case, the cutting rotation roller 44 can be driven by a servo motor to perform cutting with high accuracy.
本發明之切斷用旋轉輥並不限定於具備第1突起46及第2突起48之形態，例如，亦可為僅具備第1突起46之形態。 The cutting rotary roller of the present invention is not limited to the form provided with the first protrusion 46 and the second protrusion 48, and may be, for example, a form provided with only the first protrusion 46.
