Inline conveyor-type checkweigher
This Carton Box Check Weighing Machine is designed for inline quality control of boxed or cartoned products in packaging lines. As each box passes over a dynamic weigh zone on the conveyor, the system automatically weighs it, compares the weight to preset tolerances, and rejects any box that is under- or overweight. Constructed with stainless steel or food-grade frame, high-speed load cells, touch-screen interface and optional reject-mechanisms (pusher, air-jet, flapper), it suits applications from light cartons to heavy boxed goods. Ideal for logistics, packaging, food & beverage, pharmaceuticals or any production line where carton integrity and weight accuracy are key.
