Pass-through dispenser system with aligned feeder troughs

摘要

A dispensing system using dual linear vibratory feeders, aligned along their longitudinal axes with their dispensing ends at substantially the same vertical location. The feeder trough of one feeder penetrates the structure of the other feeder, allowing them to be aligned and compactly located. Isolation mounts may be used to damp the vibration of the feeders. An optional metering pan serves as an intermediate stage which accepts supplied material and transfers it to the feeder without compaction or bridging. Resilient mounts and an adjustable mass on the pan allow the amount of vibrational energy transmitted to the pan to be adjusted independently of the energy supplied to the feeder by the vibratory motor. A counterweight may be used to shift the center of mass of the fixed portion of the feeder into alignment with that of the vibrating portion.
