滾輪轉動之監控方法 Monitoring method of roller rotation

本發明係有關於一種監控滾輪的方法,尤其是一種可以監控滾輪轉動是否異常的方法。 The present invention relates to a method of monitoring a roller, and more particularly to a method of monitoring whether the rotation of the roller is abnormal.

在現今生產技術中,捲對捲(Roll to Roll)技術因具有可連續大量生產、製程簡單及成本較低等優點,故廣泛地應用於各個產業。於捲對捲技術中,滾輪是必要的設備之一,也是影響生產良率的主要關鍵。滾輪包含了軸心、軸承及套筒,當軸心或軸承發生故障時,會造成滾輪轉動不順暢,易造成生產異常現象及良率降低。 In today's production technology, Roll to Roll technology is widely used in various industries because of its advantages of continuous mass production, simple process and low cost. In roll-to-roll technology, the wheel is one of the necessary equipment and the main key to the production yield. The roller contains the shaft center, the bearing and the sleeve. When the shaft core or the bearing fails, the roller will not rotate smoothly, which may cause abnormal production and lower yield.

以往在檢測滾輪之軸心或軸承時,大部份是利用接觸式檢測,其又分為人工量測與儀器量測,人工量測為透過有經驗的師傅以手觸摸滾輪表面以判斷滾輪轉動是否順暢,但此種判斷方式過於主觀且無量化數據,因此易發生誤判。而儀器量測為透過震動儀或聽診器進行量測,雖可獲得量化數據,但因使用設備時必須考量使用環境中的溫度、濕度及是否具腐蝕性氣體等易造成損壞設備的因素,因此所獲得數據的準確性降低。 In the past, when detecting the axis or bearing of the roller, most of them use contact detection, which is divided into manual measurement and instrument measurement. The manual measurement is to touch the roller surface by an experienced master to judge the rotation of the roller. Whether it is smooth, but this kind of judgment is too subjective and there is no quantitative data, so it is easy to misjudge. The measurement of the instrument is measured by a vibrometer or a stethoscope. Although quantitative data can be obtained, it is necessary to consider the temperature, humidity, and corrosive gas in the environment, which may easily cause damage to the device. The accuracy of obtaining data is reduced.

除了上述利用接觸性檢測方法外,另一種為預防軸心或軸承 故障的方法是定期保養,例如定期更換相關零組件。然而,此種方法的難度在於週期設定不易,太早更換零件會造成備品零件的浪費,太晚更換又可能導致生產異常。 In addition to the above contact detection method, the other is to prevent the shaft or bearing The method of failure is regular maintenance, such as periodic replacement of related components. However, the difficulty of this method is that the cycle setting is not easy, and replacing parts too early may result in waste of spare parts, and too late replacement may cause abnormal production.

因此,不論是前述接觸式量測滾輪,或是採用定期保養滾輪頻率,皆有其缺點。故目前仍需要一種可以有效監控滾輪轉動的方法。 Therefore, whether it is the aforementioned contact type measuring roller or the regular maintenance of the roller frequency, there are disadvantages.

See also Figure 1 and Figure 2. The monitoring method for the rotation of the roller disclosed in the present invention comprises the following steps:

在步驟S21中,於滾輪100之軸心110之一外端面上設置一第一標示元件150,於第一標示元件150同一側之軸承120端面設置一第二標示元件160。其中,第一標示元件150為軸心110之圓心以外的任意點。 In step S21, a first indicator element 150 is disposed on an outer end surface of one of the shafts 110 of the roller 100, and a second indicator element 160 is disposed on an end surface of the bearing 120 on the same side of the first indicator element 150. The first indicator element 150 is any point other than the center of the axis 110.

於本發明之實施例中,第二標示元件並不限於設置於第一轉動環或第二轉動環上,而僅需滿足於滾輪轉動期間,該第二標示元件會與該第一標示元件進行相對位置移動之條件。 In the embodiment of the present invention, the second indicator element is not limited to being disposed on the first rotating ring or the second rotating ring, but only needs to be satisfied during the rotation of the roller, and the second indicating element is performed with the first indicating element. The condition of relative position movement.

在步驟S22中,使用一攝像元件對具第一標示元件150之軸心110及具第二標示元件160之軸承120端面一起進行攝像以取得一第一影像。此攝像元件例如可為電荷耦合元件(Charge-Coupled Device,CCD)或互補式金屬氧化物半導體(Complementary Metal-Oxide -Semiconductor:CMOS)感應器,但並不限於此。 In step S22, an imaging element is used to image the axis 110 having the first indicator element 150 and the end surface of the bearing 120 having the second indicator element 160 to obtain a first image. The imaging element may be, for example, a Charge-Coupled Device (CCD) or a Complementary Metal-Oxide-Semiconductor (CMOS) inductor, but is not limited thereto.

在步驟S23中,將第一影像傳送至一處理元件以定義第一標示元件150的相對第一坐標為(Xm,Ym)及第二標示元件160的相對第二坐標為(Xn,Yn)。此處理元件例如可為一電腦,但並不限於此。 In step S23, the first image is transmitted to a processing element to define that the relative first coordinate of the first indicator element 150 is (X m , Y m ) and the relative second coordinate of the second indicator element 160 is (X n , Y n ). The processing element can be, for example, a computer, but is not limited thereto.

在步驟S24中,將相對第一坐標為(Xm,Ym)及相對第二坐標為(Xn,Yn)傳送至一計算元件,以計算相對第一標示元件150與相對第二標示元件160間的距離值。此距離值例如可由下列公式計算:[(Xn-Xm)2+(Yn-Ym)2]1/2,(Xm,Ym)為第一標示元件的相對第一坐標,(Xn,Yn)為第二標示元件的相對第二坐標為(Xn,Yn)。 In step S24, the relative first coordinate is (X m , Y m ) and the second relative coordinate is (X n , Y n ) is transmitted to a computing component to calculate a relative first marking component 150 and a relative second marking. The distance value between elements 160. This distance value can be calculated, for example, by the following formula: [(X n -X m ) 2 +(Y n -Y m ) 2 ] 1/2 , (X m , Y m ) is the relative first coordinate of the first indicator element, (X n , Y n ) is the relative second coordinate of the second indicator element being (X n , Y n ).

在步驟S25中,於滾輪持續轉動期間,重覆進行前述步驟S22至步驟S24,以取得複數個距離值。 In step S25, during the continuous rotation of the roller, the above steps S22 to S24 are repeatedly performed to obtain a plurality of distance values.

在步驟S26中,將步驟S25所取得的複數個距離值依下述公式進行曲線配適(Curve fitting)後,以取得一決定係數(Coefficient of determination),公式為y(t)=a*Sin(t*2 π/p)+C,其中y為對應時間序列的各距離值,a為振幅,t為時間序列,p為週期,C為起始時間點的距離值。於本發明之一較佳實施例,於滾輪轉動的時間序列意指滾輪轉動時的各時間點t=1、t=2、t=3、......t=10(秒),將前述步驟的距離值帶入此公式,進行正弦函數之曲線配適後,取得一決定係數。當決定係數越趨近於1,代表滾輪轉動正常。反之,當決定係數越趨近於0,代表滾輪轉動異常。 In step S26, the plurality of distance values obtained in step S25 are curve-fitted according to the following formula to obtain a coefficient of determination, and the formula is y(t)=a*Sin. (t*2 π/p)+C, where y is the distance value of the corresponding time series, a is the amplitude, t is the time series, p is the period, and C is the distance value of the starting time point. In a preferred embodiment of the present invention, the time series of rotation of the roller means that each time point t=1, t=2, t=3, ... t=10 (second) when the roller rotates, The distance value of the previous step is brought into the formula, and after the curve of the sinusoidal function is fitted, a coefficient of determination is obtained. When the coefficient of decision becomes closer to 1, it means that the roller rotates normally. Conversely, when the decision coefficient approaches 0, it means that the wheel is rotating abnormally.

在步驟S27中,監控上述之決定係數,以判斷滾輪轉動是否異常。於本發明之一較佳實施例中,當決定係數小於0.9,則判定滾輪轉動異常。此決定係數的設定可預先設定,或根據檢測人員的實際維修情況進一步調整,並不限定於任一特定方法。 In step S27, the above determination coefficient is monitored to determine whether the wheel rotation is abnormal. In a preferred embodiment of the present invention, when the coefficient of determination is less than 0.9, it is determined that the roller is abnormally rotated. The setting of the determination coefficient can be set in advance or further adjusted according to the actual maintenance condition of the inspector, and is not limited to any particular method.
