Problems solved by technology

[0004] However, it is difficult to carry out pattern matching only in the sewing process, and it is important to consciously cut the pattern matching of each part in the cutting process.

Embodiment approach 1

[0053]

[0054] figure 1 The whole structure of the automatic cutting machine which implements the cutting method of this invention is shown. The automatic cutting machine 1 is composed of a cutting machine main body 3 , a cutting unit 4 , a cover sheet feeding device 5 , a data processing device 6 , a controller 7 , a projector 8 , a camera 9 and a cutting unit driving device 10 .

[0055] On the upper surface of the cutter main body 3, there is provided a table 31 on which the cut patterned sheet 2 (shown with a part cut away in the figure) is placed. The table 31 is constituted by a conveyor belt, and the sheet 2 fed out from a spreading device (not shown) is conveyed in the direction of arrow A by the conveyor belt, and spread on the table 31 . Moreover, the surface of the table 31 is covered with the bristle brush 32 (only a part is shown) so that the table 31 may not be cut at the time of cutting.

[0056] In the following description, as figure 1 As shown, the shee...

Embodiment approach 2

[0126] In Embodiment 1, the cutting of the sheet having the grid-like pattern was described, but in the cutting of the sheet having the stripe-like pattern, the processing steps up to cutting are somewhat different. In this embodiment, refer to Figure 7 The processing procedure for cutting a sheet having a striped pattern will be described focusing on points different from cutting a sheet having a grid pattern.

[0127] Figure 7 (a) is a figure which arrange|positioned the figure of the cut-out member 22a and 22b on the sheet|seat 2A which has the pattern 21A of stripe-shaped vertical stripes. and figure 2 Similarly, in order to make the description easier to understand, a state in which two members are arranged on the square sheet 2A is shown.

Abstract

A method for cutting a sheet comprises cutting the sheet which is placed on a working platform and with patterns along a pattern of a component, wherein, data used for the clipping is corrected corresponding to extension and deflection of the sheet. A pattern (22) of a component is configured on a pattern (12) which is theoretically provided by a sheet that is formed on an imaginary plane (11) corresponding to the sheet (2), each component is provided with pattern indentical points (14). Then, by taking the theoretic pattern (12) as a reference pattern (15), a projector is used to project the reference pattern (15) to the sheet (2) with an actual size, in addition, position and shape of the reference pattern (15) are made to move and deform consistently with position and shape of the pattern of the sheet (2), thereby correcting coordinate data. The corrected coordinate data of the pattern (22) of the component and a pattern of the sheet (2) which is taken by a camera are overlapped to perform display, positions of the indentical points (14) of the component which are corresponding to the pattern of the sheet (2) are interlapped, thereby correcting the coordinate data again.

Description

technical field [0001] The present invention relates to a cutting method for cutting a sheet of cloth or the like placed on a table into parts of a predetermined pattern, and an automatic cutting machine using the method. Background technique [0002] When fabrics, textiles, etc. are made into products such as clothing, it is necessary to cut out each part called a front body, a back body, and a sleeve from a sheet material such as cloth. Usually, an automatic cutting machine is used to cut the sheet placed on the table based on the shape data of each part output from the controller. [0003] On the other hand, when a patterned sheet is used to make clothing or the like, it is necessary to align the patterns in the process of sewing each part. When the pattern that characterizes each part, such as a front body and sleeves, does not match during sewing, the commodity value as clothing material will fall. [0004] However, it is very difficult to carry out pattern alignment ...
