Abstract: A system for controlling a line speed of a conveyor belt of a conveyor system during product changeovers in a wallboard production line includes a computer processor, a calculation module for calculating a predetermined mass rate of a supply of ingredients transported on the conveyor belt and deposited into a mixer during a product changeover period, and a speed adjustment module for adjusting the line speed of the conveyor belt, using the processor, based on at least one of the predetermined mass rate and the line speed of the conveyor belt for reducing an overshoot during said product changeover period.

Abstract: System for controlling a conveyor system in a wallboard production line, including a computer processor and a deadband tuning module for controlling at least one of a line speed of a conveyor belt, a foam air amount for a slurry, and an amount of water deposited into a mixer. The deadband tuning module calibrates and sets a hysteresis threshold value based on input data of at least one of the line speed, the foam air amount, and the amount of water. The input data is collected over a predetermined period. A database is provided for storing at least one statistical information of the input data during the predetermined period. The deadband tuning module determines a deadband range based on the hysteresis threshold value and the at least one statistical information using the processor.

Abstract: A system is provided for controlling a line speed of a conveyor belt of a conveyor system during product changeovers in a wallboard production line. A central control module controls operation of a position sensor and a database. The position sensor is located on top of a conveyor table for providing positional information of a slurry head formed in front of a forming plate of the conveyor system. A position detection module receives a position signal from the position sensor, and determines whether the slurry head is located within a predetermined distance relative to the position sensor based on the position signal. A speed adjustment module regulates the line speed of the conveyor belt based on the position signal.

Abstract: Embodiments of a system and a method for detecting voids in a cementitious board can be used in connection with the manufacture of products, including cementitious board products such as gypsum wallboard, for example. Such systems and methods can be used to generate numerical void measurements based upon a series of thermal images obtained during the continuous manufacture of the cementitious board.
