TRANSFER-ROLLER DESTACKER

摘要

A destacking conveyor and a roller transfer device. The destacking conveyor includes an infeed conveyor feeding articles to a roller transfer device at a first elevation. A discharge conveyor at a lower elevation receives articles dropped from the roller transfer device. The roller transfer device comprises an array of closely spaced rollers whose axial lengths decrease with distance from the infeed conveyor to form an oblique drop-off edge over which articles drop and unstack.

主权项

1. A destacking conveyor comprising:
a first conveyor having an exit end at a first elevation, the first conveyor conveying a mass flow of articles off the exit end; a roller transfer system disposed at the exit end of the first conveyor at the first elevation to receive articles from the first conveyor, wherein the roller transfer system extends in a length direction from an upstream end proximate the exit end of the first conveyor to an opposite downstream end and includes a plurality of closely spaced rollers rotatable on axes arranged to transfer articles away from the exit end of the first conveyor; a second conveyor disposed at a second elevation lower than the first elevation below the roller transfer system to receive articles dropping off the roller transfer system; wherein the axial lengths of the rollers decrease monotonically from the upstream end to the downstream end of the roller transfer system.
