Description

Technical Field

[0001] This invention relates to the field of leather preparation technology, and more specifically, to a method for layout of genuine leather and its preparation method. Background Technology

[0002] After leather is shaped during production, it needs to be cut to meet the production requirements of various products. The most crucial aspect is the leather cutting process. Currently, production is generally carried out by manually placing die-cutting molds or using cutting machines, covering many fields including automobiles, shoes, and bags. To maximize the utilization of limited leather space, leather layout technology has been widely applied in the leather industry, primarily in the footwear sector. Due to the inherent characteristics of leather, there are significant differences in nap length and texture in different locations. Traditional layout methods focus more on leather utilization and cannot guarantee the nap length and texture consistency between different shoe styles. This leads to substandard product quality and significant production costs for companies. A new layout method has been invented that groups all components of a shoe into an adjacent area for layout. Based on a powerful iterative algorithm, it achieves intelligent area selection and intelligent area outline recognition during layout. This layout method effectively solves the problem of inconsistent thickness, nap length, and texture within the same pair of shoes, improving the craftsmanship of shoe manufacturing and better meeting market demands for footwear products. Summary of the Invention

[0003] To address the shortcomings of current materials, this application provides a genuine leather layout method and its preparation method. This invention calculates the total area of ​​the shoe's cut pieces based on the area of ​​each component in a shoe. Through algorithmic calculations, it intelligently selects regions for the leather material. By classifying regions into levels, it enables the layout of each component of a single shoe to be completed within as adjacent areas as possible. This ensures a certain utilization rate and effectively solves the problems of inconsistencies in thickness, nap length, and texture among different components of the shoe upper.

[0004] This invention provides a method for typesetting genuine leather, comprising the following steps:

[0005] S101. Calculate the total area of ​​each component piece of a single or double shoe;

[0006] S102. Intelligent selection of layout areas on leather based on the total area of ​​single and double shoe components;

[0007] S103. Perform a leveling operation on the selected layout area, prioritizing the arrangement of cut pieces within the same or adjacent areas;

[0008] S104. Intelligent recognition of the area outline of a pair of shoes that has been laid out;

[0009] S105. For the identified outlines that have already been included in the layout, the layout calculation for the remaining cut pieces can be performed by removing the areas that have already been included in the layout before calculating the layout.

[0010] Preferably, the step of calculating the sum of the areas of the cut pieces of each component of a single or double shoe includes:

[0011] Based on the area data of each component piece of a single or double shoe imported into the layout software, the program calculates the total area of ​​each component piece.

[0012] Preferably, the step of intelligently selecting the layout area on the leather based on the total area of ​​each component of a single shoe includes: due to the influence of the leather itself, different areas of the same piece of leather may have significant differences in color, texture, and hair length. Assuming that the color, texture, and hair length of all the leathers to be paired do not change abruptly, the layout of the cut pieces of the single shoe close together can ensure that the color, texture, and hair length of a pair of shoes remain consistent. The layout area is divided into areas a, b, c, or more.

[0013] As a preferred option, the total area of ​​the cut pieces of all components of a pair of shoes is X feet. Using X feet as the standard parameter, the algorithm selects the area as follows: First, the first selection area is made in the leather, which is an area area a of size X feet. Area a is composed of many cells. Area a is the area selected by the black thick line. Taking one-tenth of the total area of ​​the cut pieces of a single pair of shoes, which is X feet, as the standard, the size of each cell in area a is X×10-1 feet.

[0014] As a preferred approach, when irregularities or defects in the leather edges prevent some cells from reaching an area of ​​X × 10⁻¹ feet, the algorithm calculates the missing area and, following a top-down, left-to-right order, creates new cells in region b to compensate for the missing area in region a. An initial layout calculation is then performed. If, after simulation, the algorithm finds that the X-foot area is insufficient for the layout of all parts of a shoe, a second region selection is initiated. The size of the second selected region is based on the rightmost column of cells in region a from the first selection, with the selection priority also being top-down and left-to-right. This expands to the second selected region b. If region b is also affected by factors such as leather edge contours or defects and cannot match the area of ​​the rightmost column of cells in region a, the algorithm proceeds accordingly. The above operation is repeated, adding cells from area b to area c to make up for the missing area in area b. After obtaining the size and position of the second selected area b, the algorithm performs a second simulation layout. If areas a and b still cannot meet the layout requirements for single and double shoes, the above operation is repeated to calculate the cells of the third selected area c, and the simulation layout continues until the algorithm finds that areas a, b, and c meet the layout requirements for single and double shoes. The algorithm then stops selecting areas and divides areas a, b, and c into three levels, namely A, B, and C. The priority of placing the pattern pieces during layout is also determined according to the level. The algorithm prioritizes layout in the A level area, and then completes the layout of the remaining parts in the B and C levels in turn. If the layout requirements cannot be met, the simulation layout of the next area continues.

[0015] As a preferred method, the steps for intelligently recognizing the regional outline of a pre-laid-out pair of shoes include:

[0016] After the layout of the first pair of shoes is completed, the algorithm will automatically identify the area after the pattern pieces are laid out and generate a new outline. The specific calculation logic is as follows: after the layout of a pair of shoes is completed, the pattern piece arrangement is obtained. The program generates a new outline based on the outlines of all the outermost pattern pieces in the area. Since there are gaps between the pattern pieces, when passing through the gap between two pattern pieces, and the gap size is too small to insert any of the pattern pieces in the shoe, the extension of the outline can ignore the small gap and extend directly to the contact point closest to the outline of the next pattern piece. Repeating the above calculation can obtain an identification line that fits the outline of the pattern piece.

[0017] When the gap between two fabric pieces is large enough to fit any fabric piece, the extension of the outline will perfectly match the fabric piece outline. If areas b or c still have empty space after being included in the layout, the empty space in that area will be automatically removed. When encountering special cases such as a protruding, elongated, or recessed edge of the leather, the algorithm will avoid these special shaped areas when selecting the first area, i.e., the A-level area, and will use such areas as candidate areas for the B-level area or a lower-level area. In addition, the algorithm will also calculate special cases such as defects and holes according to the requirements of on-site production. When encountering a defect and production requirements do not allow the defect to be occupied, the algorithm will identify the outline of the defect and obtain the corresponding defect size. When selecting an area, the area loss caused by the defect will also be made up by adding cells from other areas to ensure the integrity of the current area size. The calculation method for holes is the same as for defects.

[0018] Preferably, for the identified outlines already involved in layout, the step of removing the areas already involved in layout before calculating the layout of the remaining cut pieces includes:

[0019] Based on the outline of the cut pieces after layout, the algorithm will remove the area within the outline and only use the area outside the outline as the area for subsequent layout. The calculation method is the same as when calculating the layout of the first pair of shoes. The layout calculation will divide the leather into many areas.

[0020] The present invention has the following beneficial effects:

[0021] 1. This invention effectively solves the problem of product defects caused by inconsistencies in factors such as component thickness, nap length, and texture during footwear production, thereby improving product quality and craftsmanship.

[0022] 2. This invention, through the enhancement of iterative algorithms, makes the layout of the typesetting more reasonable.

[0023] 3. This invention optimizes the production process, making footwear cutting and layout more intelligent and standardized. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0033] Example 1:

[0034] The technical solution of this application is a genuine leather typesetting method, including:

[0035] S101. Calculate the total area of ​​each component piece of a single or double shoe; based on the area data of each component piece of a single or double shoe imported into the layout software, the program calculates the total area of ​​each component piece.

[0036] S102. Intelligent selection of layout areas on the leather based on the total area of ​​the components of a single shoe and a pair of shoes; Due to the influence of the leather itself, there may be significant differences in color, texture, and hair length in different areas of the same piece of leather. Assuming that the color, texture, and hair length of all the leathers to be matched do not change abruptly, the layout of the cut pieces of the single shoe and the pair of shoes can ensure that the color, texture, and hair length of a pair of shoes remain consistent.

[0037] In this embodiment, the total area of ​​the cut pieces of all components of a pair of shoes is 0.5 feet. Using 0.5 feet as the standard parameter, the algorithm's region selection process is as follows: First, a region of area 'a' with a size of 0.5 feet is selected in the leather material. Region 'a' is composed of many cells, such as... Figure 1As shown, area 'a' is the region outlined in bold black. Using one-tenth of the total area of ​​a single shoe piece (0.5 feet) as a standard, each cell within area 'a' is 0.05 feet. However, if irregularities or defects in the leather edges prevent some cells from reaching 0.05 feet, then… Figure 1 In regions 1, 2, 3, 6, 11, and 12, the algorithm calculates the size of the missing area and, following a top-down, left-to-right order, creates new cells in region b to compensate for the missing area in region a. An initial layout calculation is then performed. If, after simulation, the algorithm finds that the 0.5-foot area is insufficient to accommodate the layout of all parts of a shoe, a second region selection is performed. The size of the second selected region is based on the rightmost column of cells in region a selected in the first round. Figure 1 Cells 3, 8, and 15 are selected in a top-down, left-to-right order, expanding to the second selected area, area b. Figure 1 In cells 4, 9, and 16, if area b is also affected by factors such as the edge contour or defects of the leather and cannot be equal in area to the rightmost column of cells in area a, then repeat the above operation, that is, add cells from area b to area c to make up for the missing area in area b. After obtaining the size and position of the second selected area b, the algorithm performs a second simulation layout. If areas a and b still cannot meet the layout requirements for single and double shoes, repeat the above operation to calculate the third selected area c. Figure 1 Cells 5, 10, and 7. At this point, the algorithm has already created three areas within the leather, as shown below. Figure 2 As shown, the simulation layout continues. If, after the simulation, the algorithm finds that regions a, b, and c already meet the layout requirements for single and double shoes, the algorithm stops selecting regions and divides regions a, b, and c into three levels: A, B, and C. Figure 5 As shown, the algorithm determines the placement priority of cut pieces based on their level when laying out the layout. It prioritizes layout in the A-level area, and then completes the layout of the remaining parts in the B and C levels in turn.

[0038] S103. Perform a leveling operation on the selected layout area, prioritizing the arrangement of cut pieces within the same or adjacent areas;

[0039] S104. Intelligently recognize the outline of the area of ​​a pair of shoes that has already been laid out; after the layout of the first pair of shoes is completed, the algorithm will automatically recognize the area after the cut pieces are laid out and generate a new outline, such as... Figure 2As shown, the specific calculation logic is as follows: After completing the layout of a pair of shoes and obtaining the arrangement scheme of the cut pieces, the program generates a new outline based on the outlines of all the outermost cut pieces in that area. Because there are gaps between the cut pieces, when passing through the gap between two cut pieces, and the gap size is too small to fit any cut piece in the shoe, the extension of the outline can ignore the small gap and extend directly to the contact point closest to the outline of the next cut piece. Repeating the above calculation yields an identification line that fits the cut piece outline. When the gap size between two cut pieces is large enough to fit any cut piece, such as... Figure 3 and Figure 4 As shown, the extension of the outline will perfectly match the outline of the cut piece. Figure 2 The bold black line segment represents the outline identified by the algorithm. If there are still empty spaces in area b or c after layout, the empty spaces in that area will be automatically removed.

[0040] S105. For the identified outlines that have already been included in the layout, the layout calculation for the remaining cut pieces can be performed by removing the areas that have already been included in the layout before calculating the layout.

[0041] Based on the outline of the cut pieces, the algorithm removes the area within the outline and only uses the area outside the outline as the area for subsequent layout. The calculation method is the same as when calculating the layout of the first pair of shoes. The layout calculation will divide the leather into many areas, such as... Figure 6 As shown.

[0042] Example 2 differs from Example 1 in that: in step S104, when encountering special situations such as a protruding, elongated, or recessed piece on the edge of the leather, ... Figure 5 As shown, when selecting the first region, i.e., the A-level region, the algorithm avoids these special-shaped regions and uses them as candidate regions for the B-level region or lower-level region. In addition, the algorithm will also calculate special cases such as defects and holes according to the requirements of on-site production. When a defect is encountered and production requirements do not allow the defect to be occupied, the algorithm will identify the outline of the defect and obtain the size of the corresponding defect. When selecting a region, the algorithm will also make up for the area loss caused by the defect by adding cells from other regions to ensure the integrity of the current region's area size. When a hole is encountered, the calculation method is the same as for defects.
