INTRODUCTION
India is fast developing industrially. The industrial growth, particularly during the last decade, has been considerable. This growth, of course, is not free from the attendant problems. In a country like ours, which has mainly an agricultural based economy, the industrial development is very likely to change the existing conditions.
Low Cost Automation
Low Cost Automation (popularly known as LCA), is the introduction of simple pneumatic, hydraulic, mechanical and electrical devices into the existing production machinery, with a view to improving their productivity. This would also enable the operation of these equipment by even semi-skilled and unskilled labor, with a little training. This will involve the use of standardized parts and devices to mechanize or automate machines, processes and systems. Utilizing a human being as a source of energy is an inefficient method, in addition to being boring and monotonous to the worker.
The aim of the project is to fill oil to three different height compressor. This type of filling is used in many industries. By this process, we are able to fill the different classes of objects. With the advent of liberalization and globalization, it is necessary that industries explore method of enhancing automation and productivity to acquire greater competitiveness. In the regard, low cost Automation (LCA) is a technology that promises to be very useful for any kind of manufacturing organization.
PROGRAMMABLE LOGIC CONTROLLERS (PLC)
PLC can be defined as a digital electronic device that uses a programmable memory to store instructions such as logic, sequencing, timing, counting and arithmetic to control machines or processes. The purpose of a PLC was to directly replace electromechanical relays as logic elements, substituting instead a solid digital computer with a stored program, able to emulate the interconnection of many relays to perform certain logical tasks.
PLC software
Bosch Rexroth IndraLogic PLCs are used to build PLCs programming in Ladder logic. IndraWorks is the carrier system for integration of the Bosch Rexroth engineering tools. Rexroth IndraLogic is based on the CoDeSys technology of Smart Software Solutions (3S). IndraLogic 1.32 is based on CoDeSys version 2.3, service pack 4. IndraLogic puts a simple approach to the powerful IEC 61131-3 language at the disposal of the PLC programmer.
IDENTIFICATION OF EXISTING PROBLEM
The problems that were persisting in the field of filling machine were identified and noted down. They are as follows.
• Manual inspection are slower and inaccurate practice in mass production.
• The rate of production was affected due to the use of manual inspection systems.
• Comparatively low quality assurance to the customers.
• Sometimes in special environments which are dangerous and not conductive for human operation.
CONCLUSION
The main aim of this project is to provide a low cost automated oil filling system. The present system will provides a great deal of applications in the field of low cost automation, especially in mass production industries where there are large number of components to be processed and handled in a short period of time and there’s need for increased production.
