The numbers of packages processed by the machine which are counted by the counter are 15-17. We neglect the time consume for the package to travel from one terminal to another. A buzzer was added into the system to alert the labour to collect the package. When the thermocouple senses high temperature from heater the system/production will stop automatically. Emergency stop button added into the system if there is any malfunction occurs.
