Cutting out product manufacturing method and cutting product manufacturing planning system

The present invention relates to a method of manufacturing a cut product and a manufacturing system for the cut product. [CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to and the benefit of the benefit of the benefit of the benefit of the benefit of the benefit of the disclosure of This case is for reference.

In general, a product formed with a film (or sheet) is manufactured in the form of a material having a size larger than the size of the product to be actually used. For example, such products may include a polarizing plate for use in a display device or the like, or an optical member such as a phase difference plate. In a specific example, the polarizing plate supplier (manufacturer) will have a material having a length and a width greater than the length and width of the actual polarizing plate to be used, taking into consideration various factors such as the efficiency of the manufacturing process and the change in the demand for the polarizing plate. A polarizing plate is manufactured.

In addition, in most cases, the material is manufactured into a belt shape by a continuous process, and the manufactured material is wound around the roll and stored. Next, the material wound around the roller is pulled out and then the material is cut into a unit product having a predetermined size (hereinafter, referred to as "single piece" or "product").

Generally, a method of cutting to simultaneously obtain a plurality of individual pieces is mainly used in cutting materials. For example, a cutting frame equipped with a plurality of cutters is used. Here, the area efficiency of the cut out unit product varies depending on the cutting method. Low cutting efficiency increases the amount of chips (i.e., waste that is discarded after the material is cut), and this ultimately leads to an increase in the manufacturing cost of the product.

A polarizing plate used in a display device such as a television (TV) is manufactured by the following processes: (1) a process for obtaining a polarizer; (2) a process for laminating a polarizer protective film; and (3) layer protection Process of film or heterogeneous film. In the process of obtaining the polarizer, most of them are obtained by dyeing and elongating a polyvinyl alcohol (PVA) film to obtain a polarizer. In the process of the laminated polarizer protective film, a triacetyl cellulose (TAC) film is adhered to both sides of the polarizer by a binder to laminate a polarizer protective film. Here, the polarizing plate may be wound around the roller during each of the processes, and the product that has undergone at least the process (3) is stored by being wound around the roller. When the product is wound around the roll as above, it is advantageous in terms of the transportability of the product to each of the processes, and the storability and handling ability in the cutting process.

Meanwhile, in some cases, cutting a polarizing plate is performed by placing an order to an external company. Here, the availability of a cutting blade for a product that can be cut out may vary for each cutting company. In addition, the availability of materials or semi-finished products for cutting may vary for each cutting company. In addition, the cutting ability, the chamfering ability, the inspection ability, etc. should be taken into consideration together. When the cutting is performed by a plurality of cutting companies as described above, the area efficiency of the material or semi-finished product during cutting may be reduced when undefined and unappropriated cutting plans are dispensed.

The present invention is directed to a method of manufacturing a cut-out product that is capable of improving the area efficiency of a material or a semi-finished product, and a manufacturing system for the cut-out product.

In order to achieve the above object, according to an aspect of the present invention, a method of manufacturing a cut-out product is provided, the method comprising: calculating an area of each combination of a material and a cutting blade for cutting the material into a plurality of single pieces Efficiency; and selecting a combination of a material for making the corresponding single piece and a cutting blade based on the calculated area efficiency.

In addition, according to another aspect of the present invention, a method of manufacturing a cut-out product is provided, the method comprising: selecting a single piece to be cut based on a desired supply amount and a storage amount; based on the selected single piece Information, information about the material, and information about a cutting blade for cutting the material into a plurality of single pieces to calculate an area efficiency of each combination of the material and the cutting blade; and based on the calculation Area efficiency to select the combination of the material used to make the corresponding single piece and the cutting blade.

In addition, according to still another aspect of the present invention, a manufacturing plan system for cutting out a product is provided, the manufacturing plan system comprising: a selection mode for selecting a single piece to be cut based on a desired amount of supply and a storage amount. And a calculation mode for calculating the material and the information based on information about the selected single piece, information about the material, and information about a cutting blade for cutting the material into a plurality of single pieces The area efficiency of each combination of cutters.

Figure 1 is a plan view illustrating a material 10 associated with the present invention.

In the present document, as a subject to be cut, a "material" is a base material on which a film (or sheet) is formed and includes any material having a relatively large size before the material is cut. Further, the type or laminated structure of the material 10 is not particularly limited in the present invention. For example, the material may be selected from an optical member or protective member formed with a film (or sheet) applied to an electrical product, an electronic product, or the like. More specifically, material 10 may be selected from optical components that are applied to display devices such as televisions and monitors. Additionally, material 10 can include a single layer body and/or a laminated body.

In one example, material 10 can be a polarizing plate. Here, the polarizing plate may have a laminated structure including a polarizer and a polarizer protective film formed on the polarizer.

The material 10 can be, for example, in the shape of a belt and can be pulled out from a roll around which the material 10 is wound. The material 10 has a predetermined width X and a predetermined length Y, and the width X and the length Y of the material 10 are not limited. Material 10 can have a width X ranging, for example, from 40 millimeters (mm) to 2,500 millimeters and a length Y ranging from 1,000 centimeters to 3,000 meters. Additionally, material 10 can have a strip shape in which length Y is relatively longer than width X.

Meanwhile, in the present document, "cutting" can be used to mean one or more selected from "slitting cutting" and "unit cutting". Further, in the present invention, "strip cutting" means longitudinally cutting the material 10 in the direction of the length Y to cut the material 10 into a semi-finished product of a belt shape, and "unit cutting" refers to the length. The material 10 is cut in the direction of Y and the direction of the width X to cut the material 10 into a unit product. Here, in the present invention, a strip-shaped semi-finished product obtained by cutting the slit is referred to as a "strip" and a cut-out product obtained by cutting the unit is referred to as " Single piece or "product". Further, in this document, a "material" cut into a single piece or a product can be used as a concept covering the strip (semi-finished product).

The single piece is a final product formed with a single sheet having a length and a width less than the length and width of the material 10, and may have, for example, a quadrangular shape.

In the present document, "area efficiency" refers to a value calculated by dividing the total area of the cut product obtained after the material 10 is cut by the total area of the material 10 before the material 10 is cut. Specifically, the area efficiency can be calculated as the ratio of the area of a plurality of individual pieces (cut products) to be cut out to the area of the material 10. The area efficiency can be shown as a percentage (%) as usual. In addition, the "cut total area of the product" can be calculated by multiplying the area of one cut product by the number of cut products produced. Additionally, maximizing area efficiency refers to minimizing the portion of material 10 that has been discarded after material 10 has been cut.

Further, in this document, "size" may be used to mean one or more selected from the group consisting of: material 10 or the width, length, area, and diagonal length of the cut product (single piece and/or strip). .

Figure 2 is a plan view illustrating a cutting blade 20 associated with the present invention.

The cutter 20 has a structure in which a plurality of cutting units 21 are evenly arranged such that a plurality of single pieces can be cut by one cut. For example, the cutting blades 20 can be arranged to have a plurality of columns. Referring to Figure 2, a cutting blade 20 having two rows 22-1 and 22-2 is shown as an example. The size of each cutting unit 21 can be determined by the horizontal length x and the vertical length y. Additionally, the size of each cutting unit 21 can be substantially the same as the size of a single piece after cutting. For example, the cutting unit 21 may be formed with an opening. Here, as in the pressing process, a plurality of individual pieces can be cut by pressing the cutting blade 20 toward the material 10. As mentioned above, the single piece can be a polarizing plate. Here, the cutter 20 can be classified into various types according to the size of the cutting unit 21 and the absorption axis (or penetration axis). That is, a particular cutting blade 20 should be used to cut a polarizing plate of a particular size and specific absorption axis. Further, the number of rows 22-1 and 22-2 and the interval between the rows may also serve as criteria for classifying the cutter 20. As described above, there are various types of cutting knives, and the size and absorption axis of a single piece that can be cut out can be determined according to the cutting blade 20. Additionally, when the same material 10 is cut with different cutting blades 20, the area efficiency of the material can vary. In addition, even when the cutting blades have the same size of the cutting unit, the area efficiency of the material when the material is cut may vary depending on the number of rows and the interval between the rows.
