Abstract
An accumulating conveyor is divided into a plurality of accumulating zones from an infeed end to a discharge end. An accumulation module is associated with each accumulating zone and includes a photo electric sensor, a microprocessor, and input/output connections. Each module is coupled to an actuator that controls the driving of the associated accumulating zone, either engagement or disengagement of the driving force to either move or stop the product thereon. The sensor detects the presence or absence of a product within its zone and communicates the same to the microprocessor. The modules may be set in a singulation mode or a slug mode, the mode determining the throughput of the product within the zone depending on the presence or absence of a product on the upstream and downstream accumulating zone. An enable/disable sleep and jam mode is incorporated into the microprocessor decision process to stop the drive force for the particular zone when no product is forthcoming and to try to dislodge any jammed package from a zone and stop the flow of product upstream thereof. Each accumulation module is in communication with the adjacent accumulation modules both upstream and downstrea…
