- 2. INTRODUCTION: • Filling is a task carried out by a machine that packages liquid products such as cold drinks or water. Traditional methods of bottle filling involved placing bottles onto a conveyor and filling only one bottle at a time. • This paper aims at filling bottles simultaneously. • The filling and capping operation takes place in a synchronized manner • The entire system is more flexible and time saving.
- 3. • The filling operations are controlled using Programmable Logic Controllers. • This is because PLC’s are very flexible, cost effective, space efficient and reduces complexity. • By programming the PLC we control the entire system. • Here we are using Delta plc. • Software used is WPL Soft.

- 5. WORKING: • To develop an automatic bottle, filling and capping system with a deduction mechanism using sensors. Automatic filling process for all the bottles simultaneously with a user defined selection for volume to be filled. • Bottles are kept in position in a carton over a conveyor belt; they are sensed to detect their presence. Proximity sensors are used for sensing the bottles. Depending on the output of the sensor the corresponding pumps switch on and filling operation takes place. • If the bottle is not present then the pump in that position is switched off, thereby avoiding wastage of the liquid. The filling operation is accompanied with a user-defined volume selection menu which enables the user to choose the volume of liquid to
- 6. • The filling process is done based on timing. Depending on the preset value of the timer the pump is switched on for that particular period of time and the filling is done.
- 7. • Once the bottles are detected in the input side the conveyor motor switches ON and it starts moving in the forward direction. The bottles then reach the desired position for filling and the conveyor stops. The corresponding pumps in process tank switch ON and filling operation takes place. For e.g. if only bottle is present then inlet valve switches ON.
- 8. SENSORS (PROXIMITY SENSORS) • Proximity sensor is a sensor that are used to detect the presence of nearby objects without coming in physical contact. Inductive sensor creates a symmetrical, oscillating magnetic field close to the sensing surface. Presence of metallic object near sensing area causes the
- 9. INLET VALUE: • The valve through which a fluid is drawn into the cylinder of a positive- displacement engine, pump, or compressor. Also known as induction valve.

- 12. CONCLUSION: The main objective of this paper is to develop a bottle filling system based on certain specifications. 1 More features can be added to this system as follows: Depending on the size, shape and weight of the bottles, Filling operations can be implemented. Capping operation can be done using a piston arrangement. 2
