CONVEYOR INCLUDING CONTROLLED PACKAGE EJECTION CAPABILITIES

摘要

Disclosed is an automated conveyor sortation and item discharge system for sorting items of varying sizes and weights to designated output destinations along a conveyor. Dual-bellows configurations are provided to provide predetermined package discharge characteristics including a planar pushing member and a "self-correction" feature. A self correcting valve mechanism controls the flow of air to the bellows members, the valve mechani sm configured to supply more air to the bellow which is less extended than the other, such that the substantially planar pushing portion of the pusher member tends to remain substantially parallel to the travel path of the conveying surface.
