Abstract:
PURPOSE: To omit the weighing time of an article carried in a small-amount weighing hopper during the weighing time of total amount of the article by simultaneously controlling the weighing of and discharge from a large- to medium-amount weighing hopper and the small-amount weighing hopper.
CONSTITUTION: A weighing and discharge control means supplies a large to medium quantity of article to a first weighing hopper 3 from a first supplying device 2 and, when the weight value of the hopper 3 measured with a load cell 11 reaches a preset small, value, stops the supply of the article from the device 2 and stores the weight value of the hopper 3. At the same time, the weighing and discharge control means makes the hopper 3 to start discharge and sets the target discharging amount of a second weighing hopper 5 based on the weight value of the hopper 3 and makes the hopper 5 to start discharge. Since the a large- to medium-amount discharge front the hopper 3 and small- amount discharge from the hopper and weighing of the discharged amounts are performed simultaneously, the weighing time required for carrying the article in the small-amount weighing hopper can be omitted.
