Simplification of engineering and precise control of manufacturing process can result in significant cost savings. The most cost-effective way, which can pay big dividends in the long run, is flexible automation; a planned approach towards integrated control systems. The aim of this project is to design a Plc (Programming Logic Controller) based automatic bottle filling system that sense the presence of bottle and level of liquid in it and then fills it accordingly up to a fixed level. In this project we developed proximity sensor using infrared sensor that detects the presence of bottle. Here we use Plc to control the filling of liquid in bottle. Plc provides the sample input to the computer and with these Ladder Logic program generates control signal for solenoid tap and that can be accessed by it through Plc.
Start and stop button is used to drive the conveyor.IR Sensor is used as an input.When bottle reaches the sensor,it senses it and input reaches the relay.The input magnetises the coil of relay and the metallic piece goes from NO to NC switch.Output is given to the valve and valve opens.Two timers are used to control the valve.One RTO timer is used to give time to the valve for which it is to be kept open.Other T-on timer is used to give delay to the RTO timer.Programming is done on plc using ladder language in such a way that when conveyor stops,valve opens and when valve closes,conveyor starts again.
POWER SUPPLY: A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use a switched-mode power supply. Some power supplies have a manual selector for input voltage, while others automatically adapt to the supply voltage. In our project we are using 2 types of power supplies 12volt and 220 volts. Here is diagram of power supply in fig 1.1/ Fig 6.4.Power supply 12 volt. I R sensor: An infrared sensor is an electronic device that emits and/or detects infrared radiation in order to sense some aspect of its surroundings. Infrared sensors can measure the heat of an object, as well as detect motion. Many of these types of sensors only measure infrared radiation, rather than emitting it, and thus are known as passive infrared (PIR) sensors. All objects emit some form of thermal radiation, usually in the infrared spectrum. In a typical infrared sensor like a motion detector, radiation enters the front and reaches the sensor itself at the center of the device. This In our project we are using IR sensor. Here is diagram of intruder sensor in fig18. Fig 6.5. IR sensor PLC (Programmable Logic Controller): Control engineering has evolved over time. In the past humans were the main methods for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to make simple logical control decisions. The development of low cost computer has brought the most recent revolution, the Programmable Logic Controller (PLC). The advent of the PLC began in the 1970s, and has become the most common choice for manufacturing controls. PLCs have been gaining popularity on the factory floor and will probably remain predominant for some time to come. Most of this is because of the advantages they offer. • Cost effective for controlling complex systems. • Flexible and can be reapplied to control other systems quickly and easily. • Computational abilities allow more sophisticated control. • Trouble shooting aids make programming easier and reduce downtime.

Widely finding application in bottling and engineering industries, the chain conveyor has railing for bottle support. The high speed motor runs when strapping process starts. We offer the range in customized dimensions as required by the client. Here is diagram of conveyer in figure 6.7. Fig 6.7. Conveyer Motor : An electric motor is an electric machine that converts electrical energy into mechanical energy. In normal motoring mode, most electric motors operate through the interaction between an electric motor's magnetic field and winding currents to generate force within the motor. In certain applications, such as in the transportation industry with traction motors, electric motors can operate in both motoring and generating or braking modes to also produce electrical energy from mechanical energy.. .
