PREVENTIVE MAINTENANCE METHOD

摘要

PROBLEM TO BE SOLVED: To preventively perform adjusting work and changing work for a consumed part by observing the degree of consumption with the lapse of year of a facility. SOLUTION: The deviation amount (x) between the predetermined pulse value in which articles G to be joined from a plurality of sub conveyors and to be conveyed on a main conveyor will pass the positions of detectors 7021 and the actual pulse value in which the articles G passed the positions of the detectors 7021 is found, the total deviation amount value (c) obtained by adding the variation (b) to the mean value (a) found by compiling statistics on the deviation amount (x) for each sub conveyor is compared with the judgment reference value (d), and the presence or absence of necessity for maintenance work is judged.
