Abstract
A novel apparatus is provided for inspecting defects in cigarette bundles layered in buckets which are fixed to a bucket conveyor. The defects include tip fall state where the top content of cigarette piece is dropped off, loss of filter and shortage in the number of cigarette pieces. The apparatus consists of a gate time measuring device, a dark time measuring device, a computing device and a comparison device. The gate time measuring device measures gate time showing the passing time of the internal length of buckets, and the dark time measuring device measures dark time showing the passing time of a defective part of cigarette and of spaces between cigarette pieces. The computing device selects the maximum value of the dark time and computes a percentage of the gate time to the maximum value. The comparison device then compares the computed value with a predetermined value so as to determine whether or not there are defects in cigarette piece bundles.
