This vibratory feeder bowl system is designed to orient and discharge rivets vertically. The 18″ bowl can hold up to 300 parts and includes a vibratory storage hopper, aluminum sound enclosure, inline track, and a dual-pocket isolation shuttle. As parts move through the inline track toward discharge, a sensor monitors when each line reaches capacity. When the sensor detects that parts are present, it triggers the finger hold-back mechanism to stop the flow until the dual-pocket shuttle has picked up the current parts and is ready for more. Once the shuttle returns to its position, the finger releases a new batch of parts for picking.
