WIPO Patent Application WO/2023/145352
Kind Code:
A1
Abstract:
Provided is a detection device (10) that detects, during conveyance of a strip-shaped corrugated cardboard sheet (5), a position at an end in a width direction of the corrugated cardboard sheet (5). The detection device (10) is provided with: a measurement means (11, 21) that measures, in a measurement range including a prescribed measurement reference point and one end in the width direction of the corrugated cardboard sheet (5), positions of a plurality of measurement points on a straight line in the width direction; and a specifying means (22) that specifies, on the basis of the plurality of measured measurement points, a true end position in the width direction in a state where the corrugated cardboard sheet (5) is not warped. The specifying means (22) calculates each of distances between adjacent measurement points, adds up all the distances to calculate a sheet width length from the measurement reference point to the end, and specifies a position separated by the sheet width length in the width direction from the measurement reference point as a true end position.
