Title:
SHEET SHAPE DETECTING DEVICE AND SHEET SHAPE DETECTING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/248448
Kind Code:
A1
Abstract:
Provided are a sheet shape detecting device and a sheet shape detecting method capable of suppressing an increase in the complexity of the device and improving detection accuracy. The sheet shape detecting device (1) detects the sheet shape of a metal sheet (S) and is equipped with a roll unit (20) having a plurality of rolls (2A-2G) on which a metal sheet (S) is placed and a moving mechanism that moves a group of two or more of the plurality of rolls (2A-2G) along the axial direction as a roll group. The plurality of rolls (2A-2G) are lined up with the width direction of the metal sheet (S) as the axial direction while forming gaps (G) in the axial direction, thereby forming first regions (A1) and second regions (A2), which are longer in the axial direction than the first regions (A1), lined up in alternation in the axial direction. In the roll unit (20), first boundary portions (B1) that switch from a first region (A1) to a second region (A2) from the center portion (C) of the axial direction toward the outside are located on flat portions (21) where the radius is constant among the rolls (2), and second boundary portions (B2) that switch from a second region (A2) to a first region (A1) are located in the gaps (G) between adjacent rolls (2). The moving mechanism can switch between a first state in which the roll group is located at a first position and a second state in which the roll group is located at a second position that is moved in the axial direction from the first position by the length (L1) of the first region (A1) and less than the length (L2) of the second region (A2).
