Multihead Weigher Packing Machine

UMEO's Multihead Weigher Packing Machinery achieves precise,high-speed filling of granular products by using multiple independent weighing hoppers and a central computer constantly receives weight readings from all weigh hoppers to instantly calculate the optimal combination of hopper weights that sum to the exact target weight. Step-by-step working principle: At first product feeding from some conveyor hopper or supply tank above the weigher,and product flows down into distribution vibrator to convey the product outward towards the collection hoppers.Then the collection hoppers with some bulk quantity of product and temporarily hold product and release it on demand to the weigh hoppers;the weight hoppers that are typically 10,14,16 or 24 independent weigh hoppers arranged in a circle,which is mounted on its own high-precision load cell which continuously measures the exact weight; meanwhile the CPU instantly performs hundreds or thousands of combinatorial calculations;usually it identifies the optimal combination of 3,4,5 or sometimes more weigh hopper whose summed weights come closest to the exact target weight to discharge by CPU signal.At this time,only the selected weight hoppers in the winning combination open their discharge gates simultaneously.So the multihead weigher also called combination weigher,computer combination weigher and multihead scale.
