An offtake conveyor with a load-cell-based rejection system is an automated material handling solution used in production lines to weigh products in motion and automatically reject items that do not meet specified weight criteria. This system is commonly referred to as a check weigher with an integrated rejector.
Core Components
? Infeed Conveyor: Spacers or aligns incoming products to ensure they pass over the load cell one at a time with consistent gaps.
? Weighing Conveyor (Load Cell Bed): A highly sensitive, isolated conveyor section mounted directly on one or more strain-gauge or EMFR (Electro-Magnetic Force Restoration) load cells. It measures the precise weight of the product as it moves across.
? Offtake/Outfeed Conveyor: Receives the product from the weighing section. This section houses the tracking sensors and the actual physical rejection mechanism.
? Rejection Mechanism: A mechanical device triggered to remove out-of-spec products from the main line.
? Control Panel (HMI/PLC): The brain of the system. It processes the analog/digital signal from the load cell, compares it against the set target weight tolerances, and signals the rejector.
