  • Piezoelectric vibration generator and vibratory parts feeder incorporating the same
    Patent number: 5008580
    Abstract: A piezoelectric vibration generator interconnecting a base and a vibratory conveyor table of a piezoelectrically driven vibratory parts feeder includes a pair of resilient plate members joined together at their lower ends and disposed in a configuration substantially folded about the joint therebetween. The vibration generator of the folded configuration has a relatively small length and hence is capable of reducing the overall height of the vibratory parts feeder. A further advantage attained by the folded vibration generator is that the amplitude of vibrations is not limited depending upon the distance between the base and the vibratory conveyor table.
