Conveyor jam detection system and method

摘要

A conveyor jam detection system and method includes a distance detector located on one side of a conveyor oriented to detect the distance from the detector to parcels on the conveyor. A controller is responsive to the distance detector and is configured to compare distance measurements, to reset a jam count if different distance measurements over time are greater than a threshold, to increment the jam count if different distance measurements over time are less than the threshold, and output a jam condition signal if the jam count exceeds a set limit.

1. A conveyor jam detection system comprising:
a distance detector located on one side of a conveyor oriented to measure the distance from the detector to parcels on the conveyor; a controller responsive to the distance detector and configured:
to compare distance measurements,to reset a jam count if distance measurements differ greater than a threshold,to increment the jam count if distance measurements differ less than the threshold, andoutput a jam condition signal if the jam count exceeds a set limit.
