Abstract
A weighing vibratory apparatus and method. In one embodiment, an infeed vibratory conveyor element feeds a bulk product to a weighing vibratory conveyor element. In another embodiment, bulk product is fed directly to a weighing vibratory conveyor element and flow rate is determined by measuring the loss of weight therefrom. The weighing vibratory conveyor element includes a weight measuring apparatus that weighs the product at the same time that the product is being dispensed through vibrations. The weight measuring apparatus may be coupled to the vibratory conveyor element through damping mechanisms. An electrical signal output of the weight measuring apparatus may be low-pass filtered to provide an improved signal for feeding to a controller for controlling the flow rate.
