Trap Design for Vibratory Bowl Feeders
vibratory bowl feeder. It consists of a bowl lled with parts surrounded by a helical metal track (Boothroyd et al., 1982; Boothroyd and Dewhurst, 1983). The bowl and track undergo an asymmetric helical vibration that causes parts to move up the track, where they encounter a sequence of mechanical devices such as wiper blades, grooves and traps.
