Abstract

A tray shuttle and a tray conveyor using the tray shuttle to route magnetic conveyor trays from one conveyor section to another. The trays and the shuttles are propelled by linear-motor stators that produce electromagnetic flux waves that interact with the magnetic fields of permanent-magnet arrays in movers in each tray. Each shuttle has a main holder mover and one or more other movers connected to a linkage that operates one or more pushers that push trays off a tray holder on the shuttles.
