Japanese Patent JP2565547
Kind Code:
B2
Abstract:
A three mass, two trough feeder transfers articles on first and second troughs by vibrating the troughs. First and second leaf springs support the troughs on a base with the troughs in line with each other and with one trough overlapping the other. The ratio of the spring constant of the first leaf springs to the first trough mass equals the ratio of the spring constant of the second leaf spring to the second trough mass. An electromagnetic driver between one of the troughs and the base is excited with a signal having a frequency with an angular velocity equal to the square root of the ratio. A plurality of feeders may be positioned radially outwardly about the periphery of a conical head for distributing articles.
