Abstract

A vibratory feeder system is disclosed which employs control circuitry for controlling one or a plurality of vibratory feeders such that product is discharged at a constant weight per unit time. This is preferably achieved by deriving a weight analog representative of product weight and then using this information for controlling product velocity as by modulating the tray velocity or varying the flow of product from a supply source to the tray.
