555970 A7 B7 五、發明説明（1 ) (發明所屬之技術領域） 本發明是關於一種合成樹脂薄膜等的片狀製品之缺陷 記號方法及裝置。 (習知技術） 以往，在合成樹脂薄膜或紙等的製程中，以一定寬度 而且在長又大的帶狀狀態下自動地施以各種處理，最後依 照製品規格切斷成爲所定形狀。檢測未滿足製品規格的缺 陷部分，也在帶狀狀態下自動地進行，而在後續製程能將 缺陷部分之識別成爲容易地，施以記號。例如在製造被使 用於液晶顯示面板的偏光板之際，在合成樹脂薄膜的成形 製程，或賦予朝一定方向的延伸所產生的偏光特性等的製 程中，長又大的帶狀中間製品連續而在各製程被處理，藉 由製品規格被切斷成事先決定的大小或方向。爲了自動地 進行缺陷檢查，必須將缺陷的檢測與有關於缺陷的記號， 沿著片狀製品的搬運路徑加以進行。 第6圖是表示一般性的缺陷記號方法。第6 ( a )圖 是表示裝置的槪略構成；第6 ( b )圖是表示施以記號的 製品狀態。如第6 ( a )圖所示，在記號裝置中，對於以 一定寬度的帶狀並以一定速度搬運的片狀製品1，以攝影 機2攝影表面，並藉由畫像處理進行缺陷3的檢測。在片 狀製品1的搬運方向的下游側，標號器4配設於寬度方向 的一端或兩端。當藉由攝影機2檢測到缺陷3，則在寬度 方向包括缺陷部分，配合從配設攝影機2的位置一直搬運 本紙張尺度適用中國國家標準（ CNS ) A4規格（210 X 297公釐） (請先閱讀背面之注意事項再填寫本頁) 裝· *11 經濟部智慧財產局員工消費合作社印製 -4 -

3 0 4 2 9 5號公報，在移動筆而直接在缺點部位施 以記號的想法，只能在寬度方向僅能在一部位施以記號。 所以在切斷片狀製品1而切出一定形狀的區劃部分時，即 使存在缺陷3也會分成有施以記號7的區劃部分與未施加 的區劃，而對於未施以記號7的區劃部分並不知道存有缺 陷3，有被判斷爲沒有缺陷3之虞。 本發明的主要目的是在於提供一種在後續製程的可確 本紙張尺度適用中國國家標準（CNS ) A4規格（210〆297公釐） -6 -

Description of the invention (1) (Technical field to which the invention belongs) The present invention relates to a method and a device for marking defects of sheet products such as synthetic resin films. (Conventional technology) Conventionally, in the process of manufacturing synthetic resin film or paper, various treatments are automatically performed with a certain width and in a long and tape-like state, and finally it is cut into a predetermined shape according to the product specifications. Detecting defective parts that do not meet product specifications is also performed automatically in a banded state, and the subsequent processes can easily identify defective parts and mark them. For example, when manufacturing a polarizing plate used in a liquid crystal display panel, in the process of forming a synthetic resin film, or in the process of imparting polarizing characteristics caused by extending in a certain direction, a long and strip-shaped intermediate product is continuous and Each process is processed and cut to a predetermined size or direction based on the product specifications. In order to carry out the defect inspection automatically, it is necessary to carry out the detection of the defect and the mark about the defect along the conveyance path of the sheet product. Fig. 6 shows a general defect marking method. Fig. 6 (a) shows a schematic configuration of the device; Fig. 6 (b) shows a state of a product marked with a mark. As shown in FIG. 6 (a), in the marking device, for the sheet-like product 1 conveyed in a belt shape with a constant width and at a constant speed, the surface is photographed with a camera 2 and the defect 3 is detected by image processing. On the downstream side in the conveying direction of the sheet-like product 1, the labeling device 4 is arranged at one end or both ends in the width direction. When the defect 3 is detected by the camera 2, the defect part is included in the width direction, and the paper is always transported from the position where the camera 2 is installed. This paper applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (please first Read the notes on the back and fill in this page) * 11. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs-4-555970 A7 ___B7 V. Invention Description (2) (Please read the notes on the back before filling this page) When the labeler 4 is placed, the labeler 4 operates. A line-shaped mark 5 is drawn on one or both edges of the portion including the defect 3 in the width direction. As shown in FIG. 6 (b), when the sheet-like product 1 is wound to form a roller 6 ', the symbol 5 is viewed from the side in a vortex shape. In paper and the like, the part marked with 5 is removed, and it is used in the longitudinal direction. Fig. 7 is a view showing the idea of a mark of a defect marking device for a sheet-like product disclosed in Japanese Patent Application Laid-Open No. 9-3 0 2 295. In this conventional technique, as for the detection means for optically detecting a defective part, a marking device disposed on the downstream side of the sheet-like product 1 in the conveying direction is movable in the width direction. According to the position information of the defective part detected by the detection means, the pen of the marking device is moved toward the defective position in the width direction, and the tip of the pen is brought into contact with the surface of the sheet-like product 1 at the timing of any pen position to which the defective part is transported. control. With this control, the mark 7 can be directly marked on the defect position on the surface of the sheet-like product 1. (Problems to be Solved by the Invention) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, in the defect marking method shown in Figs. 6 and 7, ink-jet inks using water-based inks or water-based inks or contact pens are used. By attaching the colored ink to the vicinity of the defective part to recognize the defect, but after applying a mark on the sheet-like product, if the sheet-like product is treated with a drug in the subsequent process, the marked ink may infiltrate and disappear. In addition, by contacting the sheet product with other components, the mark may be wiped off and disappear. As the above-mentioned subsequent process, for example, when manufacturing a polarizing plate, there is a process in which a raw material component is alkalized with an alkali solution. This paper size applies Chinese National Standard (CNS) A4 specification (21〇〆297mm) -5- 555970 A7 B7 V. Description of the invention 0) (Please read the precautions on the back before filling this page) As shown in FIG. 6, the end portion in the width direction is marked with a mark '. The length range in which the mark 5 is applied to the sheet-like product 1 can only be obtained as information on where the defect 3 exists in the width direction. Therefore, when slitting or trimming the side edge portion is cut off, the part marked by 5 is cut off, and the information about the position of defect 3 is completely disappeared. Therefore, when the sheet-like product 1 is to be cut finely, it is necessary to first remove the portion marked 5 in the longitudinal direction. However, there are many parts to be removed in the length direction, including defect 3, and there are many good parts that have not been detected for defects. If many good parts are removed, the yield of the product will be reduced. In addition, if the sheet-like product 1 is cut in the longitudinal direction before the fine-cutting process, the fine-cutting process cannot be continuously performed, and thus productivity is lowered. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed a direct mark on the shortcomings as shown in Figure 7. However, it cannot reflect the information on the existence range of the defect 3 in the width direction. In the manufacturing process of the product 1, due to the influence of a roller or the like, the defect 3 is a possibility that a length in the width direction may have a certain degree or a plurality of positions in the width direction. In the case where information about such a width direction is also required, as disclosed in Japanese Patent Application Laid-Open No. 9-3 0 4 2 9 5, the idea of moving a pen and placing a mark directly on a defective part can only be in the width direction. Marks can only be placed on one part. Therefore, when cutting the sheet-like product 1 to cut out a certain shape of the division, even if there is a defect 3, it will be divided into a division with a mark of 7 and an unapplied division. I do not know that there is a defect 3, and there is a possibility that it is judged that there is no defect 3.
