Problems solved by technology

[0006] However, since the above-mentioned conventional cutting device displays the image obtained by shooting the pattern of the cloth on the display device, it is difficult to express the distortion on the display device through the pattern, and it is difficult for the operator to visually recognize the distortion, so there are cases where it is difficult to determine the distortion.
In addition, since the pattern of the cloth whose distortion is corrected by image processing is displayed on the display device, and the operator visually recognizes the display device to designate the position of the cutting pattern, it is difficult for the operator to grasp the actual position of the cutting pattern of the cloth. The problem

Embodiment Construction

[0039] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0040] The cutting device according to the embodiment of the present invention is a plotter-type cutting device that cuts cloth to produce a pattern sheet for clothing. Such as figure 1 As shown, the cutting device 1 includes a cutting table 2 , a stretching device 3 , a projection control device 4 , and a projector 5 .

[0041] The cutting table 2 includes a support surface 21 for supporting a cloth 7 as a sheet, and the cloth 7 is cut along a cutting pattern by a cutting unit 22 driven on the support surface 21 . The supporting surface 21 is formed in a brush shape with flexible bristles implanted therein, and the cloth 7 is fixed by sucking the cloth 7 through the brush-shaped supporting surface 21 by a vacuum pump (not shown). The table origin and coordinates used when driving the cutting unit 22 are set on the supporting surface 21 . Hereinafter, a cas...

Abstract

The invention provides a cutting device, capable of enable an operator to correctly identify the distortion of sheet materials, so that the operator can cut the sheet materials along the cutting patterns corresponding to the distortion of the sheet materials, as a result, the pattern sheets with less distortion can be obtained. The cutting device (1) has a cutting workbench(2), a stretching device (3), a projection controlling device (4) and a projector(5). A grid (6) is projected on the surface of a cloth (7) arranged on a bearing surface (21) of the cutting workbench (2) by the projector (5). An operator visually identifying the grid (6) operates a controller (41) to adjust the position of the adjusting points (P1 to P9) of the grid (6), so that the grid (6) is deformed along the patterns of the cloth (7). The cutting patterns (75,76) are deformed correspondingly to the deformed grid (6), and the deformed grid is projected on the surface of the cloth (7). The position and angle of the cutting patterns (75,76) are adjusted, and the cloth (7) is cut into a shape along the cutting patterns (75,76).

Description

technical field [0001] The present invention relates to a cutting device for cutting a pattern sheet without distortion from a sheet material with distortion. Background technique [0002] As a cutting device that cuts cloth for clothing to produce a design sheet, there is a plotter-type cutting device. This cutting device has a cutting table and a cutting unit. The cutting table has a support surface for supporting cloth. The cutting unit has a built-in cutting edge and is driven in a plane direction on the support surface of the cutting table. Cutting data representing a cutting pattern of a design sheet is input to a cutting device, and the cutting device drives a cutting unit based on the cutting data and operates a cutting blade to cut cloth to produce a design sheet. [0003] In most cutting devices, through a series of cutting steps, a required length of cloth is drawn from a roll formed by winding the cloth into a roll, and placed on a cutting table. Here, the clot...
