摘要：This invention relates to a method of detecting deviation in position andmisshape of transported objects which have a predetermined shape and are successivelytransported at predetermined intervals with the transported objects being maintained ina predetermined direction, comprising the steps of: generating synchronizing signalscorresponding to the transportation intervals on a predetermined cycle; detectingpassage of end portions of the transported objects at predetermined positions;calculating a time interval between the generation of the synchronizing signals and thepassage of the end portions; calculating a mean value and a standard deviation for aprescribed number of the transported objects from time series information; judging atransported object as an object of which position is deviated or shape is deformed whenthe difference between measured time interval and the mean time interval is larger thana criterion which is calculated based on the standard deviation; replacing the oldestinformation on the time interval in the time series information with information on time
interval of a transported object which is judged that a position thereof is not deviated ora shape thereof is not deformed to renew the time series information; and calculating amean value and a standard deviation for the renewed time series information so as to beused for the judgment.
