ABSTRACT:
A weighing bucket receives product dumped from an overlying holding bucket and causes an underlying load cell to produce an electrical signal representative of the weight of the product in the weighing bucket. After being weighed, the product is swept out of the weighing bucket by a high volume blast of low pressure air produced by an air entraining nozzle. As a result of using air to empty the weighing bucket, the weighing bucket requires no doors or other moving parts and thus may be constructed with high stiffness and with a high natural frequency to reduce low frequency disturbances of the weight signal and to improve the accuracy of such signal as well as to reduce the time required for the weighing cycle.
