Design and development of low cost crevice testing equipment for process industries

Abstract

Packaging is very important process in many pharmaceutical, food and manufacturing industries. For packaging most of the industries prefers plastic bottles, tins, glass bottles and plastic covers. At the time of packing it’s important to ensure the cans are not damaged. To ensure this handful of techniques are being implemented in the industry. Among them, most common technique is bubble testing method. This method has a drawback of rusting with time and high initial cost. Presence of water in the can may affect the quality of the final product in the can. To overcome these drawbacks PLC and photo resistive effect based system have proposed and developed. This proposed system is classified into transport unit, testing unit and control unit. The transporting unit is a conveyor belt arrangement, testing unit comprises of photo resistive effect based system and control unit to monitor and control overall operation of the system. The control unit rejects damaged cans from the conveyor by monitoring. This system has been developed at low cost and with faster response rate.
