COMPENSATION CONTROL METHOD AT TIME OF DELIVERY OF CONSTANT AMOUNT OF SMALL-SIZED SOLID BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for weighing and counting the greater part of a set amount in a large amount charging part and compensating the residual amount in a small amount charging part to accurately deliver raw materials in a set weight and amount, for the purpose of solving the problem that the fine adjustment of a weight and the delivery of an accurate amount can not be performed at the time of delivery of a constant amount of small-sized solids by a conventional combined weighing system. SOLUTION: The raw materials of which the weight is less than the delivery set weight of the raw materials by the weight corresponding to several raw materials are weighed in the large amount charging part and combined with the raw materials of the small amount charging part preliminarily prepared by weighing one or several raw materials to be delivered. By this method, the raw materials are accurately delivered in the set weight.
