Abstract
Methods for initiating one or more maintenance procedures on a conveyer system employ a load cell assembly that is supported by a link of a conveyor chain of the system in order to collect tension measurements. According to preferred methods, one or more threshold values for a rate of change in tension along particular portions of a circuit, around which the chain is driven, and/or for a variation in tension profile, from one cycle to another around the circuit, are established for comparison with tension measurements that are collected and/or processed by the load cell assembly, in order to detect operating issues and initiate the appropriate maintenance procedure(s). According to some methods, plots of the rate of change of tension versus time are generated and displayed for an operator to view.
