Abstract
In a circulating vibratory linear parts-feeder including: a main trough for transporting parts in one direction; and a return trough for transporting the parts in the opposite direction to the one direction, arranged closely to the main trough, and spaced with a small gap from the main trough, in which the parts are transferred from the downstream end of the return trough into the upstream end of the main trough. The parts are orientated in the main trough by orientating means and discharged from a discharge end to the outside and the other parts are returned from the downstream end of the main trough into the upstream end of the return trough. Thus the parts are being continuously circulated in the main trough and return trough. The main trough has a transport surface for orientating the parts, and an inward circulating surface which is lower than the transport surface. The return trough includes a circulating surface. The main trough and the return trough are vibrated by drives of different frequencies, respectively; and the parts are transferred from the downstream side of the return trough to the upstream end of the transport surface. The orientated parts are discharged from a discharge guide connected to the end of the main trough; and the parts being led into the inward circulating surface are transferred into the circulating surface of the return trough.
