Abstract

An article induction system for preparing a stream of articles, such as mail parcels, for processing employs a series of conveyors operating under control of a controller for feeding articles to an operator at a cull belt at an optimal paced rate. The article induction system includes a destacking section, a separation and alignment section, a buffer section and a culling section manned by an operator. A controller controls the speed of each component based on measurements provided by sensors so as to feed articles to the operator at a desired paced rate.

Claims (11)

1. A method of preparing a stream of articles for processing, comprising the steps of:

singulating the articles using a singulating conveyor to form a series of singulated articles;

aligning the series of singulated articles using an aligning conveyor comprising a narrow belt on a first side and an article pushing belt opposing the narrow belt for pushing articles towards the narrow belt;

buffering the series of singulated articles using a buffer to form a series of buffered articles; and

passing the series of buffered articles from the buffer to an operator at a selected paced rate.

2. A method of preparing a stream of articles for processing, comprising the steps of:

singulating the articles using a singulating conveyor to form a series of singulated articles;

buffering the series of singulated articles using a buffer to form a series of buffered articles; and

passing the series of buffered articles from the buffer to a cull belt manned by an operator at a selected paced rate based on a measurement from an array of sensors at an interface between the buffer and the cull belt.

3. The method of claim 2 , further comprising the step of adjusting a speed of the singulating conveyor based on a fullness measurement of the buffer.

4. The method of claim 2 , further comprising the step of releasing an article from the buffer conveyor to the cull belt when signaled by a controller.
