PLC PROJECT - 2

SYSTEM DESCRIPTION

There are two same object, one with metal casing and vice versa. First and foremost, the system will detecting the object before going the "stamp" process. Next, the inductive sensor will sense the casing of the object and there are piston A and piston B where piston A will operate if the object casing is metal and piston B will operate if the object casing is non-metal. These two piston will only operate after lifting process. Apart from that, we using another piston for lifting purpose and the process will run again when the sensor detect object in initial state.

1. Start

2. Detect object

3. Stamp process

4. Object is metal -- Piston A operate

5. Object is non-metal -- Piston B operate

6. Object exists on lift

7. Lifting

8. End
