WIPO Patent Application WO/2024/101653
Kind Code:
A1
Abstract:
According to the present invention, provided is an apparatus for removing wrinkles from a sheet material, comprising: an expander roll that rotates in a bent state with respect to a rotation axis bent to straighten and remove wrinkles formed in a sheet material being transferred to be wrinkle-removed; a roll bender that generates a bending moment to bend the expander roll; a roll rotator that rotates the expander roll; a roll controller that controls the operation of the roll bender and the roll rotator; a vision camera that photographs one surface of the sheet material being wrinkle-removed, so as to generate an input image; and a wrinkle detection module that uses the input image to detect wrinkles in the sheet material to be detected, wherein the wrinkle detection unit includes a quantification unit that quantifies the level of wrinkles formed in the sheet material being detected and produces wrinkle level information, and the roll controller adjusts, in response to the wrinkle level information, the degree of bending of the expander roll and a rotation position of the expander roll.
