Detailed Description
In order that those skilled in the art may better understand the technical solutions of the present invention, the following detailed description of the present invention with reference to the accompanying drawings is provided for exemplary and explanatory purposes only and should not be construed as limiting the scope of the present invention.
The concrete structure of the invention is as follows: the arrangement rule and calculation principle of fancy typesetting.
(1) First, fancy typesetting has symmetry and size consistency, and typesetting shape is similar to a loop shape.
(2) The calculation principle is that the matching is mainly carried out according to the size of the large material, and the size of the commonly used single-web large material is divided into: 1245mm X970mm;1245mm X1041mm;1245mm X1092mm; 4 panels are calculated according to one large material, and the calculation is totally divided into the following example authentication to be explained;
(3) as shown in fig. 2, 1245MM X970MM (4 sheets: 470X620 MM) assuming that the SET size is long (length is denoted by letter a) X wide (width is denoted by letter B) =300 mmX145MM, according to the symmetry of fancy typesetting and the principle of size consistency, the length and width of the SET size are analyzed first, and it can be seen that the Panel short side is 470MM, 300MM (a) +145MM (B), namely: the setting of the jointed boards of the short sides already obtains that the SET is 1 transverse, 1 vertical, the setting height of the known vertical SET is 300mm, the setting height of the horizontal SET is 145mm, from the setting, the horizontal height is 2 times greater than the vertical height, then 2 transverse SET jointed boards can be overlapped transversely, a 1 vertical 2 transverse structure is formed, according to the symmetry principle of the loop shape of the fancy typesetting principle, the 1 vertical 2 transverse structure formed by typesetting is duplicated and rotated 180 degrees again, and the jointed boards are spliced to the other half, and finally the fancy loop-shaped typesetting design (the same principle as that of the graphic representation 3) is met.
Namely: and the SET dimension long side is more than 2 times of the SET dimension wide side, the following 1 vertical 2 horizontal structure can be spliced, and then the reasonable typesetting quantity is matched according to the actual size of the SET dimension, and the utilization rate of the plate is maximized by combining the large-size type.
1 vertical 2 horizontal structure = SET dimension long side >2 times SET dimension wide side
(A+B+B) + (B+B+A) (180 degrees of rotation)
(4) As shown in fig. 4, 1245MM X1041MM (open 4: 518X620 MM), assuming that the SET size is long (long denoted by letter a) X wide (wide denoted by letter B) =230 mmX130MM, according to the symmetry of fancy typesetting and the principle of size consistency, it can be seen that the Panel short side is 518MM, 230MM (a) +130MM (B), that is: the setting of the jointed boards of the short sides is that SET is 1 transverse, 2 vertical, the setting height of the vertical SET is 230mm, the setting height of the horizontal SET is 130mm, from the setting, the transverse height is smaller than 2 times of the vertical height, then 1 transverse SET jointed board which is transversely SET can be overlapped to form a 1 transverse 2 vertical structure, according to the loop symmetry principle of the fancy typesetting principle, the typesetting is formed into a 1 transverse 2 vertical structure, then a loop structure is formed on 1 transverse side, and the SET in the middle is used as a reference, and the SET is duplicated and rotated for 180 degrees, so that the SET is spliced to the other half, and the SET is symmetrical, thereby finally meeting the fancy loop typesetting design.
Namely: the SET dimension long side A (smaller than 2 times of SET dimension broadside) > the SET dimension broadside B, then the following 2 vertical 1 horizontal structure can be spliced, and then the reasonable typesetting quantity is matched according to the actual size of the SET dimension, and the utilization rate of the plate is maximized by combining the large material dimension type.
2 vertical 1 horizontal+1 vertical+1 horizontal structure = SET dimension long side (less than 2 times SET dimension broadside) > SET dimension broadside X2 + SET dimension long side+SET dimension short side (A) + (B) + (B) + (B) + (A) + (A) + (B) + (B) + (B) + (A) (180 degrees rotated) -A
From the principle, the typesetting needs to form a shape of a circle, is symmetrical, is horizontally or vertically placed by combining the size of the SET, is matched according to the size of the large material, and finally achieves the maximum utilization rate of the plate.
