This paper presents the idea behind the implementation of stocker conveyor machine with the use of Programmable Logic Controller (PLC) in the automation industry. The main idea behind this machine is to design a conveyor system that conveys the unfinished jobs by loading on the pallet through indexing to gear Hobbing machine. Basic PLC functions like timing, sequencing and controlling were implemented. The hardware contains lifter and stoppers. Induction motors were used for conveyor and lifter while hydraulic cylinders were used for operating the stoppers. Operation of motors and cylinders is completely automated using PLC. The result shows that the machine gives the unfinished job to Hobbing machine one at a time and also receives the finished job from latter in synchronization.
