Detection of Quantitative Faults in Pencil Packet by Analyzing its Capacitance

K V Santhosh, Bhagya R Navada


This paper presents an automated technique for detection of quantitative irregularity in a pencil box. Objective of the proposed work is to design a system for checking the number of pencils in a sealed packet. Dielectric property of pencil is made used to compute the change in capacitance for variation in number of pencils in the pencil box. This change is capacitance is further converted to voltage for quantitative analysis using fuzzy logic algorithms. On identifying the faulty packets, action is taken to reject the packet by moving it away from conveyor. Proposed technique was designed and implemented for real life implementation in factory environment. Validation of designed system was made by testing it for a large set of pencil packets, result produced show successful implementation of proposed work.
