ABSTRACT:
A screw conveyer for conveying metal turnings from a machining operation. The chip screw conveyor includes an auger-like screw configured to move metal turnings in a given direction. The conveyor includes a tubular housing and an input chute defining an input opening. A secondary feeder arm is pivoted to the conveyor housing. The arm is pivoted out of the way in direction when agglomerated scraps/chips are dumped threw input opening into the input chute. Once the chips are dumped in place, the arm is allowed to rotate downwardly to press on the top of the agglomerated scraps/chips. This prevents the chips from "bridging" between the sides of the input chute and prevents the scraps from "balling" or rolling on top of the screw in a manner that makes the screw ineffective. The arm creates sufficient force to press the scrap into engagement with the flutes of the screw. In an alternative embodiment, an arm includes a small secondary screw mounted to the arm for moving agglomerated scraps/chips along the arm and into engagement with the underlying screw. In yet another embodiment, an arm includes a vibrator for vibrating the arm to make it more effective.
