Detailed Description

The following detailed description of the present invention is given for the purpose of better understanding technical solutions of the present invention by those skilled in the art, and the present description is only exemplary and explanatory and should not be construed as limiting the scope of the present invention in any way.

The concrete structure of the invention is as follows: the arrangement rule and the calculation principle of the fancy typesetting.

Firstly, the fancy typesetting has symmetry and consistent size, and the typesetting shape is similar to a round shape.

Secondly, the calculation principle is mainly matched according to the size of the large materials, and the size of the common single large material is divided into: 1245mm X970 mm; 1245mm X1041 mm; 1245mm X1092 mm; 4 pieces of Panel are calculated according to one large material, and the calculation is totally divided into the following example authentication for explanation;

third, as shown in fig. 2, 1245mm X970mm (open 4: 470X620MM), assuming that the SET size length (length is denoted by letter a) and the width (width is denoted by letter B) is 300mmX145mm, the length and width of the SET size are analyzed first according to the symmetry of the fancy typesetting and the principle of size consistency, and it can be seen that the short side of Panel is 470mm, and 300mm (a) +145mm (B) can be adopted, that is: the short edge is placed in the jointed board, the SET is 1 transverse and 1 vertical, the height of placing the known vertical SET is 300mm, the height of placing the transverse SET is 145mm, and the transverse height is 2 times greater than the vertical height, so that the transverse SET jointed board can be overlapped with 2 transverse SET jointed boards to form a 1 vertical 2 transverse structure, and according to the clip symmetry principle of the fancy typesetting principle, the 1 vertical 2 transverse structure formed by typesetting is copied and rotated by 180 degrees and spliced to the other half, and finally, the fancy clip typesetting design is met (the same principle of figure 3).

Namely: the long side of the SET dimension is more than 2 times of the wide side of the SET dimension, the following 1 vertical and 2 horizontal structures can be spliced out, and then the reasonable typesetting quantity is matched according to the actual size of the SET dimension, and the large material dimension type is combined, so that the utilization rate of the plate is maximized.

As shown in fig. 4, 1245mm X1041mm (open 4: 518X620MM), assuming that the SET size length (length is denoted by letter a) and the X width (width is denoted by letter B) is 230mmX130mm, according to the symmetry of the fancy typesetting and the principle of size consistency, first analyzing the length and width of the SET size, it can be seen that the Panel short side is 518mm, 230mm (a) +130mm (B) can be used, that is: the arrangement of the jointed boards of the short sides shows that SET is 1 transverse and 2 vertical, the height of the vertical SET arrangement is 230mm and the height of the horizontal SET arrangement is 130mm, and the transverse height is smaller than 2 times of the vertical height, so that 1 transverse SET jointed board can be transversely arranged in a superposed mode to form a 1 transverse 2 vertical structure, according to the clip symmetry principle of the fancy typesetting principle, the 1 transverse 2 vertical structure formed by typesetting is formed, a clip structure is formed on the 1 transverse side, the centered SET is used as a reference, the transverse SET is copied and rotated by 180 degrees, and the spliced boards are spliced to the other half to be symmetrical, so that the fancy clip typesetting design is finally met.

Namely: the SET dimension long edge A (less than 2 times of the SET dimension broadside) is larger than the SET dimension broadside B, then the following 2 vertical and 1 horizontal structures can be spliced out, then the reasonable typesetting quantity is matched according to the actual size of the SET dimension, and the large material dimension type is combined, so that the utilization rate of the plate is maximized.

By combining the above principles, the typesetting needs to be formed into a shape and a symmetrical shape, then the horizontal or vertical placement is carried out by combining the size of the SET size, and the matching is carried out according to the size of the large materials, so that the maximum utilization rate of the plates is finally reached.
