Hereinafter, the present invention will be described in detail.

2 is a process chart showing a method for manufacturing a cut product according to the present invention.

Referring to FIG. 2, in the method of manufacturing a cut product according to the present invention, in a method of manufacturing a cut product in which at least two cut lines are disposed and cut in a cut area on a fabric sheet, (a) the control unit may cut at least two cut pieces. Receiving information about a product; (b) the control unit generating a bounding rectangle model for each of the cutting products based on the information of the at least two cutting products; (c) receiving, by the control unit, information on the fabric sheet; (d) setting, by the control unit, a cutting area on the fabric sheet and placing the boundary square model in the cutting area to generate at least two cutting lines on the fabric sheet; And (e) cutting the fabric sheet using the at least two cutting lines.

The step (a) is a step of receiving information on two or more kinds of cutting products, the information on the cutting products may include information such as shape, size, structure, dimensions, quantity, number of products, etc. for the cutting products. The controller may input information about the cutting product.

In particular, the cutting product may have a structure and shape of a polygonal shape, such as a triangle, a square, etc., may have an irregular arbitrary shape, in the manufacturing method according to the present invention by cutting the fabric sheet to form a curved curve as well as a polygonal shape It is possible to manufacture cutting products of various shapes, including.

In this step, the information about the cutting product can be inputted in the form, size, structure, dimensions, etc. of the measured cutting product separately, but also through a method of recognizing using drawing data, images, etc., such as CAD. In addition, pattern data can be input through various paths.

In the step (b), it is a step of generating a bounding rectangle model for each of the cutting products based on the information of the at least two cutting products.

The bounding rectangle model (hereinafter referred to as BR model) for the cut product is modeled by representing the cut product in two dimensions and then creating a rectangle surrounding the cut product. The bounding rectangle model is the same as the two-dimensional area of the cut product, It has a larger area than that.

In addition, at this stage, one or more types of boundary rectangle models may be generated for a specific cutting product, and the minimum bounding rectangle model (MBR) is minimized to minimize the two-dimensional area of the cutting product and the area of the boundary rectangle model. model, or a minimum cutting bounding rectangle (MCBR model) that can minimize the number of cutting to reduce the manufacturing time of the cut product can be generated.

Figure 3 is a two-dimensional structure of the cutting product X, (b) the minimum boundary rectangle model (MBR model) of the cutting product X (c) the minimum cutting boundary rectangle of the cutting product X according to a preferred embodiment of the present invention A conceptual diagram showing a model (MCBR model).

Referring to FIG. 3, the BR model for cutting product X analyzes cutting product X in two dimensions to generate a diagonal line surrounding cutting product X across the cutting product X, and generates the diagonal. BR model information, which is rectangular information surrounding the cutting product X, may be generated based on a diagonal line and a vertex located at the outermost part of the cutting product. As a result, the bounding rectangle model of the cut product may help to easily determine a position for manufacturing the cut product on the fabric sheet by representing the cut product having an arbitrary shape in two dimensions. Therefore, through this method, BR model information about a polygonal cutting product such as a triangle or a square or a cutting product having an irregular arbitrary shape can be generated.

In addition, in this step, the two-dimensionally displayed cutting product X can be rotated in both directions to generate the MBR model of the cutting product X and the MCBR model of the cutting product X, respectively. Can be used as

Specifically, the MBR model generates a minimum boundary rectangle that minimizes the difference between the two-dimensional area and the area of the cut product, thereby minimizing the amount of waste generated from the cut sheet fabric when the cut sheet is manufactured to manufacture the cut product.

MCBR model can minimize the manufacturing time when cutting the fabric sheet to produce the cutting product by creating a minimum cutting boundary square model that can minimize the number of cutting when cutting the fabric sheet to manufacture the cut product. . That is, referring to FIGS. 3 (b) and 3 (c), in the case of the MBR model of the cutting product X as shown in FIG. 3 (b), the spaces 1 to 4 are finally present in the boundary rectangular model. In order to create the cutting product, the cutting must be performed a total of four times. In the case of the MCBR model of the cutting product X, as shown in FIG. Must be performed once.

Therefore, the MBR model can be used when the expensive fabric sheet is utilized, and the MCBR model can be used when the manufacturing process cost is higher than the unit price of the fabric sheet. Based on the information, it is possible to generate a boundary rectangle model for each cutting product, selectively select a boundary rectangle model as needed, and use the selected boundary rectangle model to generate cutting lines to be described later.

In addition, in this step, the shape of the cutting product may be included in the BR model represented by two points, and the BR models are also simply expressed in two points in a complex form of the cut product and placed at a specific position on the fabric sheet. The fabric sheet is divided into two-dimensional areas by appropriately arranging a plurality of cutting products, and the fabric sheet is disposed on the fabric sheet so as to reduce the amount of waste generated from the fabric sheet waste which is cut and discarded, or to shorten the manufacturing process time. Can be.

In the step (c), as a step of receiving information on the fabric sheet, in this step, the information of the fabric sheet can be input through the control unit, the information of the fabric sheet is the shape, size, structure, dimensions of the fabric sheet Information may be included.

The fabric sheet is not particularly limited in material, structure, type or laminated structure, and manufactures pads, seals, suction materials, sound insulation materials, insulation materials, packaging materials, and the like, which are used in the general fields of automobiles, heavy industries, and electronics. It may be a fabric utilized to, and may be used by introducing a single layer fabric or a laminated fabric of a structure laminated two or more layers as a fabric sheet, but is not limited thereto. The fabric sheet may be marked with an area of rectangular structure in the form of a sheet (or film), and may be used by introducing one having a sufficient area to produce two or more kinds of cutting products having different shapes and structures by creating a cutting line.

In addition, the fabric sheet may use a roll fabric wound in a roll, or may introduce both sheet-like fabric sheets, and the width and length of the fabric sheet are not limited. Preferably, the fabric sheet may be a foam type fabric sheet for pad manufacturing used for automobiles, electrical and electronic equipment, industrial equipment, interior materials, and the like.

In step (d), the cutting area is set on the fabric sheet, and the boundary rectangular model is disposed in the cutting area to generate at least two cutting lines for each cutting product on the fabric sheet. In order to manufacture the cutting products, at least two cutting lines may be generated by placing a BR model of two or more cutting products generated in the above-described steps on the sheet, thereby reducing the amount of waste generated from the sheet sheet. have.

4 is a conceptual diagram illustrating a state in which at least two cutting lines are generated by arranging a plurality of cutting rectangles for each cutting product on a fabric sheet according to an exemplary embodiment of the present invention.

Referring to FIG. 4, in this step, at least two cut lines models may be generated on a sheet of fabric using a specific program, and the at least two cut lines models may correspond to a BR model of a final cut product for manufacturing a cut semifinished product. It may include (1) a virtual cutting line representing the same area and (2) a product cutting line to represent a real two-dimensional area of the cutting product located in the BR model of the cutting product to manufacture the cutting product.

Specifically, the specific program described above calculates the area of each BR model for each of the plurality of cutting products to derive the total area, selects an arbitrary area on the fabric sheet to exceed the total area, and then selects two or more cutting products. Create a virtual cut line model (shown as a dotted line in FIG. 4) having a minimum area so that the BR models for the sheet are properly disposed on the sheet without overlapping, and the usage of the cut sheet is minimized. can do.

That is, in this step, the area of the fabric sheet is calculated using the size and dimension information of the fabric sheet input in the step (c), the area of each cut product is calculated, and then the cut product is placed on the fabric sheet. In addition, it is possible to form a virtual cutting line so that the cutting product is densely arranged on the fabric sheet to minimize the amount of waste of the fabric sheet.

In addition, in this step, it is possible to generate and display the coordinate value of the BR model for each cutting product on the fabric sheet, to generate the coordinate value (ax, ay) of the lower left of the BR model, the coordinate value of the upper right (bx , by) can be generated and displayed respectively, and the area of the cutting product for manufacturing the cutting product can be calculated using the corresponding coordinate values, and the BR model of each cutting product placed on the virtual cutting line of the fabric sheet You can check the location.

Therefore, the virtual seam cutting line can be utilized for zero cutting semi-finished product for manufacturing the cutting product, and the cutting semi-finished product can be manufactured through the additional cutting process along the product cutting line.

5 is a tree that allows BR models for a plurality of cutting products to be placed in any area of a fabric sheet in order to create at least two cut lines in any area of the fabric sheet in accordance with a preferred embodiment of the present invention. It is a conceptual diagram which shows the arbitrary structure of a hierarchical structure and a fabric sheet.

Referring to FIG. 5, in this step, the total sum of the areas of each of the two or more kinds of cutting products is calculated, and then an arbitrary area is partitioned on the fabric sheet using information of the fabric sheet to form a hierarchical tree structure R on the fabric. You can create and mark a tree index.

The R-tree index is set by partitioning any cutting area on the sheet, and creating any cutting area as the highest level node (node without parent node) among the nodes of the tree called root. do.

In addition, each node area is created by partitioning the space of the highest level node created using the bounding rectangle model of each foundation product, and creating a lower level node so as to minimize the amount of waste generated from the fabric sheet. Thus, at least two cutting lines may be generated in a short time without additional calculation, and the cutting lines may include both a virtual cutting line for manufacturing the cut semifinished product and a product cutting line for manufacturing the cutting product.

At this time, by using the method of sequentially placing the BR model of the largest cutting product of the BR model of the cutting product, it is possible to shorten the creation time of the virtual cutting line, and the product cutting for the actual cutting product manufacturing within the virtual cutting line Lines can also form structures that include them.

For example, the R-tree index for generating cut lines on the fabric sheet is classified as A by the highest level node A by marking any area on the fabric sheet as A, and the BR models for each cut product are formed in a tree hierarchy. It can be divided into parent node, child node, sibling node, and so on and distributed.

In addition, by separating the upper node and the lower node and then mark the area may be calculated the amount of waste generated in the fabric sheet waste generated in any cutting area of the fabric sheet.

Therefore, if each node region is separated based on the area of each of the plurality of BR models using the R-tree index, as shown in FIG. 5, node A 40, which is an arbitrary cutting region on the fabric sheet, is lowered. Has a structure containing child nodes Aa, Ab, and Ac, and Aa (10) also includes child nodes Aa-1 (4), Aa-2 (3), and Aa-3 (2), Ab (10) includes only Ab (10), Ac (15) generates a virtual cut line model and a product cut line having a hierarchical tree structure containing Ac-1 (6) and Ac-2 (8) In addition, the generated virtual cutting line model may be disposed on the fabric sheet through the batch algorithm MBR model or MCBR model to reduce the processing time of the cutting product, or minimize the amount of waste generated from the fabric sheet.

Therefore, in this step, since the area of the fabric sheet and the area of the cutting product can be expressed as the actual values without distortion, the information of the complicated hierarchical structure with many child nodes or high order can be represented without distortion, and the cutting product The location of each node can be displayed for each node information, so that the visibility of the hierarchical structure becomes clearer.

In addition, each node is stacked on the parent node to solve the cognitive problem of the existing two-dimensional tree map, it is possible to interpret the hierarchical structure as both inclusion and top-level relationship.

In addition, in this step, in order to efficiently visualize the position where the cut product is placed on the far sheet, a tree map can be generated, and the R-tree index of the hierarchical tree structure recursively divides the MBR model to give the far sheet. By filling the spaces of the spaces, it is possible to effectively arrange and visualize a plurality of cutting products and to reduce the amount of fabric sheet waste that is discarded after being cut.

In addition, in order to continuously manufacture a plurality of cutting products, by designating an additional cutting area of the arbitrary region B on the fabric sheet to generate two or more cutting lines having various shapes in succession, thereby manufacturing the cutting products Do it.

Therefore, in this step, the BR models of the plurality of cut products are placed on any area of the cut sheet in a short time, and at least two cut lines models are generated to shorten the processing time of the cut product, or The amount of waste generated can be minimized.

In addition, in this step, at least two cutting line models are generated on the fabric sheet, and then the product cutting lines having the same virtual cutting line as the generated virtual cutting line model and the actual cutting products located inside the BR model It may be configured to further include the step of printing on the upper surface of the fabric sheet.

Therefore, as described above, the virtual cutting line and the product cutting line are separately printed and formed on the surface, thereby cutting along the boundary rectangle of the cutting product to manufacture the cutting semifinished product, and additionally cutting the manufactured cutting semifinished product along the product cutting line. It may be configured to manufacture a cut product, that is, the cut semi-finished product means a rectangular shaped cut cut along a virtual cut line generated according to the bounding rectangle model displayed on the sheet of fabric.

In addition, when the virtual cutting line and the product cutting line are separately printed as described above, it is possible to check whether the cutting of the semi-finished product and the cutting product has been precisely performed. It can also be easily cut through, greatly reducing the manufacturing time.

In particular, in the present step, during the process of printing the virtual cut line and the product cut line on the fabric sheet, further comprising the step of forming a position tag for displaying the position at a point corresponding to the top, bottom, left and right corners of the virtual cut line model Can be configured to

The location tag as described above can check the position of the fabric sheet when cutting the fabric sheet through the prohibition of the location tag to check whether the cutting is precisely performed with the naked eye or a recognition device. It helps to check whether the printing is precisely marked on the fabric sheet.

In the step (e), the fabric sheet is cut using the virtual cut line model to manufacture two or more types of cut products, and each cut product is cut for each node along the virtual cut line indicated in the virtual cut line model. To manufacture each cut semi-finished product, and further cut the manufactured cut semi-finished product to manufacture each cut product.

The process of manufacturing the cut product may be divided into two methods according to the cutting means, and when the cutting means uses a jet water knife, a laser beam light source, or the like as the cutting means, the cutting part 200 may be formed on at least two cutting lines. It is possible to manufacture the cutting product by cutting the fabric sheet directly along the product cutting line exhibiting the same two-dimensional structure as the cutting product located inside the BR model in the included virtual cutting line and product cutting line.

Alternatively, in the case of using a metal knife or a heat medium knife as the cutting means, the cutting part 200 cuts the fabric sheet in the horizontal axis direction (X) and the vertical axis direction (Y) along a virtual cutting line to manufacture the cut semi-finished product, and then cut the product. Cutting products can also be manufactured by additional cutting along the line.

In the method for manufacturing a cut product according to the present invention as described above, a boundary square model is generated for a plurality of cut products having a random shape as well as a polygonal product, and then fabricated using the generated boundary square model. Two or more types of cutting lines can be planetary on the sheet in a short time, and the fabric sheet can be cut along the created cutting lines to shorten cutting time and improve productivity.

In addition, the method for manufacturing a cutting product according to the present invention, by performing the cutting process through the mechanization can reduce the product defect rate and greatly improve the quality and uniformity, it is possible to improve the working environment of the worker.

In particular, in the case of inputting information by setting various cutting product products of the same material used in automobile vehicles in one set configuration, a plurality of cutting products having various shapes on the fabric sheet may be manufactured through one set of cutting processes. This can reduce production time and cost, and can also continuously manufacture various cutting products used in the same vehicle model, thereby greatly improving productivity.

The model generation module 320 may generate BR model information for each cutting product by using the cutting product information input by the information input module 310. To do this, the model generation module analyzes the cutting product in two dimensions to generate a diagonal line surrounding the cutting product across the cutting product, and generates the cutting product based on the created diagonal and the vertex located at the outermost part of the cutting product. BR model information, which is enclosing rectangle information, may be generated, and one or more boundary rectangle models may be generated by rotating the cutting product in both directions. In particular, the boundary rectangle model for each cutting product may generate a minimum boundary rectangle model (MBR model) in which the two-dimensional area of the cutting product and the area of the boundary rectangle model are minimized, or the manufacturing time of the cutting product is minimized by minimizing the number of cuttings. It is also possible to create a minimum cut boundary rectangle model (MCBR model) that allows for shortening.

The positioning module 330 calculates the placement position and direction of each cutting product by using the information of the fabric sheet input through the information input module 310 and the boundary rectangle model generated by the model generation module, and virtually displays the fabric sheet. You can create a crop line.

At this time, the positioning module 330 uses the information such as the material, price of the fabric sheet and labor cost information such as MBR model, or MCBR model that can reduce the manufacturing time of the cutting product by minimizing the number of cutting By selecting the BR model for a plurality of cutting products can be placed on the sheet sheet to generate a virtual cut line model.

The generation of the virtual cut line model may be generated in an arbitrary area of the fabric sheet, and a virtual cut line may be generated in a short time without additional calculation by arranging each node area using the area of the cut product.

In addition, the positioning module 330 may generate and display the coordinate values of the BR model for each cutting product on the fabric sheet, generate the coordinate values (ax, ay) at the lower left of the BR model, and coordinate at the upper right. Values (bx, by) can be generated and displayed respectively, and the area of the cutting semi-finished product for manufacturing the cutting product can be calculated using the corresponding coordinate values, and the cutting product located on the virtual cutting line of the fabric sheet. Check the location of the star BR model.

In addition, the two-dimensional area of the BR model for each cutting product is calculated, the total sum of the calculated areas is calculated, and then an arbitrary area exceeding the total sum of the calculated areas is generated on the fabric sheet to obtain the highest level node. You can separate it by A and mark the area in parentheses.

The storage module 340 may store information generated by the information input module 310, the model generation module 320, and the positioning module 330, and if necessary, transmit the stored information to an external device or display device. It serves to display on the display unit (not shown). The storage module 340 may use various storage means conventionally used for storing information.

The control module 350 serves to control the above-described fabric sheet supply unit and the cutting unit so as to manufacture the cutting product.
