另外,另一方案的本發明是一種光學膜輥狀物的製造系統,其一邊輸送具有圖案的長條片狀的光學膜坯料一邊對該光學膜坯料進行分切,將得到的長條片狀的光學膜捲繞成輥狀而製造光學膜輥狀物,其中,具有:放出部,其從光學膜坯料輥放出前述光學膜坯料;輸送部,其將從前述放出部放出的前述光學膜坯料向下游輸送;攝像部,其對由前述輸送部輸送的前述光學膜坯料的前述圖案進行攝像;校準部,其基於由前述攝像部攝像而得到的攝像結果來調整前述光學膜坯料的寬度方向位置;分切部,其配置於比前述攝像部靠下游側的位置,將由前述輸送部輸送的前述光學膜坯料沿長度方向連續地切斷,由此得到前述長條片狀的光學膜;捲繞部,其將通過前述分切部得到的前述光學膜捲繞成輥狀。 According to still another aspect of the invention, there is provided a system for producing an optical film roll which cuts the optical film material while conveying a long sheet-shaped optical film material having a pattern, and obtains a long strip shape. The optical film is wound into a roll to produce an optical film roll, and has a discharge portion that discharges the optical film blank from the optical film blank roll, and a transport portion that discharges the optical film blank from the discharge portion. The imaging unit transmits an image of the optical film blank conveyed by the transport unit, and the calibration unit adjusts a position of the optical film blank in the width direction based on an imaging result obtained by the imaging unit. a slit portion which is disposed on a downstream side of the image pickup portion, and continuously cuts the optical film blank conveyed by the transport portion in a longitudinal direction to obtain the long sheet-shaped optical film; The optical film obtained by the slitting portion is wound into a roll shape.

根據該結構,由於基於光學膜坯料的圖案的寬度 方向位置來調整該光學膜坯料的寬度方向位置,因此能在相對於圖案適當的位置高精度地對該光學膜坯料進行分切。 According to this structure, due to the width of the pattern based on the optical film blank The position of the optical film material in the width direction is adjusted in the direction position, so that the optical film material can be slit with high precision at an appropriate position with respect to the pattern.

另外,作為上述發明的一實施形態,前述攝像部在使被輸送的前述光學膜坯料與沿前述光學膜坯料的長度方向形成為圓弧狀的凸曲面密接的狀態下對前述圖案進行攝像。 Further, in an embodiment of the invention, the image pickup unit images the image in a state in which the conveyed optical film material is in close contact with a convex curved surface formed in an arc shape along a longitudinal direction of the optical film material.

根據該結構,能消除光學膜坯料的輸送中的偏差,減少測定圖案的寬度方向位置時的測定偏差,因此能在相對於圖案更適當的位置高精度地對光學膜坯料進行分切。 According to this configuration, variations in the conveyance of the optical film blank can be eliminated, and measurement deviation in the width direction of the measurement pattern can be reduced. Therefore, the optical film material can be slit with high precision at a position more appropriate for the pattern.

根據該結構,由於圖案的邊界(邊緣)明顯,因此攝像的圖像鮮明,能減少圖案的寬度方向位置的測定誤差。相對於攝像部而言,與以透射光方式照射圖案相比,以反射光方式照射圖案時圖案的邊界(邊緣)更明顯,因此優選。 According to this configuration, since the boundary (edge) of the pattern is conspicuous, the image captured is sharp, and the measurement error of the position in the width direction of the pattern can be reduced. It is preferable that the boundary (edge) of the pattern is more conspicuous when the pattern is irradiated with reflected light than the image irradiated by the image pickup unit.

另外,作為上述發明的一實施形態,前述校準部具有調整前述放出部的寬度方向位置的放出位置調整部。 Further, in an embodiment of the invention, the calibration unit includes a release position adjustment unit that adjusts a position of the release unit in the width direction.

The determination unit (position information acquisition unit) 91 of the information processing device 90 detects the reference line of the image obtained by the image analysis. As shown in FIG. 3, the detected reference line is used as a detection line. It is determined whether the detection line is in a predetermined standard position within the field of view of the camera (the width direction position where the reference line should exist) (or is disposed within a predetermined range). The determination unit 91 measures, for example, the vertical distance from the right end of the viewing range (imaging region) to the reference line (detection line), and determines whether or not the measured value is within a predetermined value. When the determination unit 91 determines that the position in the width direction of the reference line is at a predetermined position (a position in the width direction where the reference line should be present) (or is disposed within a predetermined range), the determination unit 91 may perform no instruction, for example, or may The monitor 95 of the display unit outputs an image.

另一方面,在判斷部91判斷為基準線(檢測線)未位於預先設定的標準位置(基準線應該存在的寬度方向位置)(或未配置於規定的範圍內)的情況下,運算部92求出放出部10的移動方向和移動量。運算部92例如測定基準線自 前述標準位置的偏移方向及偏移量來求出放出部10的移動方向(與偏移方向相反的方向)和移動量。移動量可以與偏移量相同,可以比偏移量大,也可以比偏移量小。然後,控制部93向後述的放出位置調整部60指示上述求出的移動方向和移動量。 On the other hand, when the determination unit 91 determines that the reference line (detection line) is not located at a predetermined standard position (a position in the width direction where the reference line should exist) (or is not disposed within a predetermined range), the calculation unit 92 The moving direction and the amount of movement of the emitting unit 10 are obtained. The calculation unit 92 measures, for example, the reference line from The moving direction (the direction opposite to the offset direction) and the amount of movement of the emitting portion 10 are obtained by the offset direction and the offset amount of the standard position. The amount of movement can be the same as the offset, and can be larger than the offset or smaller than the offset.

<實施例> <Example>

實施例1是上述實施形態1的結構,實施例2是上述實施形態3的結構。比較例1除了代替實施例1的第一攝像部41而 使用巡線感測器以外,與實施例1相同。作為評價,改變膜輸送速度而僅分切600m的量,在分切後的光學膜的長度方向上以1m間隔測定20點從分切端面到基準線(邊緣)的距離,求出測定距離的偏差R。將其結果示於圖7中。圖7中,橫軸表示輸送速度,縱軸表示偏差。 The first embodiment is the configuration of the first embodiment described above, and the second embodiment is the configuration of the third embodiment. Comparative Example 1 is used instead of the first imaging unit 41 of Embodiment 1. The same as in the first embodiment except that the line sensor is used. In the evaluation, the film transport speed was changed, and only the amount of 600 m was cut, and the distance from the slit end face to the reference line (edge) was measured at intervals of 1 m in the longitudinal direction of the slit optical film, and the measurement distance was determined. Deviation R. The results are shown in Fig. 7. In Fig. 7, the horizontal axis represents the conveying speed, and the vertical axis represents the deviation.

實施例1及實施例2能在比比較例1更適當的位置高精度地進行分切。在巡線感測器的情況下,在視場內存在多條線的情況下,不明確是檢測了哪條線,不能適當地測定基準線的寬度方向位置,因此,可推測分切位置的偏差變大。另外,巡線感測器在將高速膜輸送速度高速化時或速度變動時,分切位置的偏差變大。存在弄錯本來應檢測的基準線或不能高精度(清楚)地檢測本來應檢測的基準線、不能正確地測定應檢測的基準線的傾向。另外,具有兩種寬度方向調整功能的實施例2與具有一種寬度方向調整功能的實施例1相比,在即使更高速的情況下也能在相對於圖案適當的位置進行分切。 In the first embodiment and the second embodiment, the slitting can be performed with high precision at a position more appropriate than that of the comparative example 1. In the case of the line sensor, when there are a plurality of lines in the field of view, it is unclear which line is detected, and the position of the width direction of the reference line cannot be appropriately measured. Therefore, the position of the slit can be estimated. The deviation becomes larger. In addition, when the high-speed film conveying speed is increased or the speed is changed, the line-of-sight sensor has a large variation in the slitting position. There is a tendency to correct the reference line to be detected or to detect the reference line to be detected with high accuracy (clearly) and to not accurately measure the reference line to be detected. Further, in the second embodiment having two kinds of width direction adjustment functions, compared with the first embodiment having one width direction adjustment function, it is possible to perform slitting at an appropriate position with respect to the pattern even at a higher speed.
