SORTATION CONVEYOR

摘要

IMPROVED SORTATION CONVEYOR An improved lever arm for a tilt tray sortation conveyor has formula defined unlatching and tipping cam sections. The tipping cam section imparts a constant angular acceleration of about 20 radians/sec.2 to the tray during positive tipping. Such angular acceleration produces a maximum tangential acceleration for any article on the tray, approximately equal to or less than the acceleration of a free falling body. An improved tray latch or index plate has an inclined cam resisting rebound of the tray after initial tipping. Integral shock absorbers disperse impact forces in tray tip-up apparatus and resist elongation of tip-up mounting pin holes. Methods are claimed.
