More Information
Summary:According to one embodiment, a diagnostic system includes a conveyor device first and second sensors and a diagnostic device. The conveyor device includes an endless chain having a plurality of rollers coupled at regular pitches and each fit into a bush, to circularly move between a first sprocket and a second sprocket. The first and second sensors diagonally are disposed apart from each other on a moving path of the chain, irrespective of an operating direction of the conveyor device, to detect a passage of each of the rollers of the chain. The diagnostic device measures an amount of elongation of the chain based on a first detection signal output from the first sensor and a second detection signal output from the second sensor according to movement of the chain during operation of the conveyor device.
