Design and fabrication of tablet strips counter and shifter machine

Abstract

The applications of conveyor are increasing day by day in the manufacturing industries due to its flexibility and accuracy in material handling. Industries like packaging and food processing uses conveyor for the rapid production and less power utilization in material handling. In general, only a single type of object likes tablets, bottles or trays are monitored and controlled on a single conveyor in pharmaceutical industries. The trays or boxes on the conveyor are to be stopped at the required station and material to be filled in the trays on conveyor. This can be done using the induction type proximity sensors and counters placed at different positions in the system. In given system, we have done the design and fabrication of semi-automatic tablet counting and shifting mechanism in belt conveyor used in the packaging and transportation system in tablet packaging for pharmaceutical industries. The number of trays/boxes to be filled by tablets can be transfer by using arrangements of proximity sensors and pneumatic locking along with counting system. The output packaging fixed can be easily altered in between the process.
