Definitions
- the present invention relates to a method for cutting two kinds of rectangular unit pieces having different optical properties from a base material sheet by cutting using a cutting frame including a cutter.
- the technique of manufacturing a plurality of rectangular unit pieces having a relatively small size by cutting a long length of the base sheet has been used in various fields. For example, a long length base material sheet having a constant width is repeatedly cut by the cutting frame, and a plurality of rectangular unit pieces are simultaneously cut in one cut.
- the size (width) of the base material sheet is specified due to various factors such as the limitation of the base material sheet supplier, the efficiency of the manufacturing process, and the fluctuations in the demand for the rectangular unit pieces, while the size of the rectangular unit pieces is as necessary It is often different.
- the efficiency of the cutting varies greatly depending on how the cutting operation is performed. Low cutting efficiency increases the amount of cutting scrap of the base material sheet discarded after cutting, which ultimately increases the manufacturing cost of the rectangular unit pieces.
- the cutting loss rate is determined by sequentially placing the rectangular unit pieces at positions having such a ratio relationship. Can be minimized. However, when such an integer proportional relationship is not established, the cutting loss rate may vary depending on the arrangement of the monomers. Furthermore, when cutting the rectangular unit pieces according to the optical orientation of the base sheet to be cut differently, a large amount of cutting scrap is inevitably generated.
- a method for increasing the cutting rate of the base sheet is also very important in terms of manufacturing cost of the rectangular unit pieces.
- the cutting rate of the base material sheet may typically vary depending on the conditions of the cutting process, the structure of the cutting frame, and the like. That is, high cutting efficiency may be achieved by an operation configuration for maximizing utilization of the base sheet in the cutting process, an arrangement configuration in which cutters for cutting rectangular unit pieces from the base sheet are optimized, and the like.
- an arrangement configuration in which the rectangular unit pieces corresponding to the cutters are adjacent to each other is generally arranged by arranging cutters (for example, knives) in the cutting frame. It is used.

Therefore, the rectangular unit pieces 20 and 30 are arranged according to the optical direction 15 of the base sheet 150 and 160.
- the rectangular unit pieces 20 may be formed to cut the 'A' unit pieces 20 having an optical direction 25 parallel to the optical direction 15 of the base sheet 150. It is arranged on. However, since an integer proportional relationship does not hold for the width W of the base material sheet 150 with respect to the width of the rectangular unit body 20, cutting loss of the portion W3 x L0 remaining after cutting is generated.
- the rectangular unit pieces 30 are formed of the base sheet 160 to cut the 'B' unit pieces 30 having the optical direction 35 orthogonal to the optical direction 15 of the base sheet 160. It is arranged on. However, since the width W of the base material sheet 160 does not have an integer proportional relationship with respect to the length of the rectangular unit body 30, the cutting loss of the portion W4 x L0 remaining after cutting is generated.
- two or more kinds of rectangular unit pieces having different optical directions have different base sheet material materials depending on the optical directions. Therefore, different types of rectangular unit pieces may not be arranged on the same base sheet to utilize a portion remaining after cutting.
