Title:
METHOD AND SYSTEM FOR MEASURING THE SETTING TIME OF A GYPSUM BOARD
Document Type and Number:
WIPO Patent Application WO/2024/079199
Kind Code:
A1
Abstract:
A computer implemented method (5000) for in-line, real-time monitoring of the time- temperature profile of a continuously produced gypsum board (1013) in a gypsum board manufacturing line (1000). The method (5000) takes as input the signals S-IR of a series of infrared sensors (2001a-d) placed at given distances along the gypsum board manufacturing line between the moulding stage (1001) and the cutting stage (1003) of said gypsum board manufacturing line (1000), and further takes as input the speed S-GB of the continuously produced gypsum board (1013) on the gypsum board manufacturing line (1000). The method (5000) provides as output a corrected time-temperature profile (CTT) of the continuously produced gypsum board (1013). The method (5000) further comprises the following steps: (a) converting (5001) the signals of the series of infrared sensors (2001a-d) into a time- temperature profile based on the speed S-GB of the continuously produced gypsum board (1013) on the gypsum board manufacturing line (1000); (b) processing (5002) the time-temperature profile through a correlation model (C-M) and/or a physical model P-M to calculate a corrected time-temperature profile (CTT).
