Abstract:
In a circulating vibratory linear parts feeder including;(a) a main trough for transporting parts in one direction; and (b) a return trough for transporting the parts in the opposite direction to said one direction and arranged closely to said main trough and spaced therefrom with a small gap whereby said parts are transferred from a downstream end of said return trough into an upstream end of said main trough, orienting means in said main trough for orientating parts therein and for discharging the oriented parts from a discharge end to the outside and for returning other parts from a downstream end of said main trough into an upstream end of said return trough whereby said parts are being continuously circulated in the main trough and return trough, the improvements comprising said main trough including a transport surface for orientating said parts and an inward circulating surface being lower than said transport surface; said return trough including a circulating surface; said main trough and said return trough having respective vibratory drives of different frequencies; and means for transferring said other parts from a downstream end of said return trough to an upstream end of said transport surface of said main trough; a discharge guide connected to the end of said main trough for discharging the oriented parts; and means for transferring the parts being led into said inward circulating surface into said circulating surface of said return trough.
