Project Summary

The objective of this paper is to design, develop and monitor “Tablet filling and capping using PLC with SCADA”. This project provides with a lots of benefits like low power consumption, low operational cost, less maintenance, accuracy etc. This project is a vast application used in number of industries like milk industries, chemical, food, mineral water and many industrial manufactures. Our paper aims at filling and capping bottles simultaneously. The filling and capping operation take s place at a same time but with some intervals. It also includes a user-defined number of tablets selection menu through which the user can input the desired number of tablets to be filled in the bottles. The entire system is much more flexible and time saving. Tablet Filling is a task that is carried out by an automated machine. In this project, the filling of the bottles is controlled by using a controller known as PLC which is also the heart of the entire system. A programmable logic controller (PLC) is a digital computer used for the automation of various electrochemical processes. We have controlled the entire system by the help of PLC and the ladder diagram. Also to design, the SCADA screen has been used for monitoring of the purpose.

Project Objectives

The field of automation has had a notable impact in a wide range of industries beyond manufacturing. Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services. Automation plays an increasingly important role in the world economy. Automation puts this continuity into consistent practice. Totally Integrated Automation covers the complete production line, from receipt of goods, the production process, filling and packaging, to shipment of goods. So by implementing the use of PLC’s in these processes, industries will initiate towards the era of new industrialization. PLC plays a very important role in the world of automation. It makes the whole process simple, flexible and accurate. A tablet filling system with PLC allows the user to fill the bottle till a desired level without wastage of the tablets. Ladder logic is used to control the sequence of the PLC. In addition to this, the use of SCADA has also been implemented for the monitoring of the entire system

Project Implementation Method

METHODOLOGY Bottles are kept in position over a conveyor belt. They sensed the presence of those bottles. IR sensors are used for sensing the non-metallic bottles and inductive sensors for metallic bottles. Depending on the output of the sensor the corresponding containers will switch on and tablet filling operation takes place. In metallic bottles red tablet will be filled and in non-metallic bottles yellow tablets. If a particular bottle is not present then the container in that position is switched off, thereby avoiding wastage of the tablets. The filling operation is followed with a user-defined number selection menu which enables the user to choose the number of tablets to be filled. The filling process is done based on timing. Depending on the preset value of the timer the container is switched on for that particular period of time and the filling is done. After filling operation, the capping operation is done. One container puts a cap on every bottle and another will press it tightly for the convenience purpose.

Benefits of the Project

HARDWARE DESCRIPTION

1) PROGRAMMABLE LOGIC CONTROLLER A programmable logic controller (PLC) is a digital computer used for the automation of various electrochemical processes. It is the Heart of the entire Automation System. We are using PLC because they are flexible, easy to program and space efficient.

2) SOLENOID VALVE It is an electromagnetic valve which is used to control the flow of various types of liquids. By opening and closing the desired amount of liquid or no. of tablets is selected. It is very much efficient to use in the automation process.

3) SENSORS In this project we have used Optical and Inductive sensors. Inductive sensors sense the metallic type bottles whereas optical sensors sense the non-metallic type bottles. These sensors play a vital role in automation type project.

4) DC MOTOR The main use of the DC motor is for the Conveyor system. Conveyor Belt is used to make the different types bottles move forward followed by the DC Motor. The motor used in our project works on 12V DC supply. The speed of the motor is 10- 12 RPM. In the
