Device for intermittently receiving and continuously delivering objects

摘要

An endless chain passing about a constantly rotating driving wheel and a chain-tensioning driven wheel carries alternately-disposed first and second rollers, with object-driving fingers on the first rollers. Along the upper run of the chain is a fixed ramp having a lower rolling track for the first rollers and an upper rolling track for the second rollers whereby the chain is accordion-folded at a location corresponding to a zone on a table for intermittently receiving objects to be delivered between the fingers. After the fixed ramp is a vertically-reciprocating mobile ramp which produces an intermittent stopping of the fingers in said zone, while allowing the objects taken-up to leave the table with the chain unfolded and hence with a regular pitch and at constant speed.
