Abstract Nowadays Automation plays a vital role in industrial applications. This proposal deals with PLCs (Programmable Logic Controller) for automation in material handling. This system is mainly used for storing and retrieving the unprocessed materials in a manufacturing unit. We use proximity sensors to detect the nearby objects. The main objective of this paper is to built an automation system coordinated by using PLC integration. Keywords- Proximity Sensor–Programmable Logic Controller –Conveyor

I. INTRODUCTION A Programmable Logic Controller, is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. It is a solid state device that uses soft wired logic contained in the controller’s memory to duplicate the functions of relays and hard wired solid state control devices. In operation, the memory unit sequentially scans inputs (Sensors, limit switches, push buttons, photo cells) in cyclic fashion to determine which output (contacts, motor starters, pilot lights, converters) should be turned on or off. It uses a programmable memory to store instructions and execute specific functions that include ON/OFF control, timing, counting, sequencing, arithmetic and data handling.

II. IMPORTANCE OF AUTOMATION Automation plays a very important role in our generation. It has brought a drastic changes in home applications and industries. One of its applications in the industry is automated storage and retrieval system (ASRS). ASRS is an integrated engineering system that requires the knowledge of electrical, electronics, mechanical and computer engineering in its design. The storage retrieval equipment consists of special mechanism responsible for transferring the products input/output to a point in the shelves, a system for recording and arranging the products, a system for reading and executing an order, a system for locating and retrieving the products through an advanced technology.

III. EXISTING SYSTEM In dynamic industrial location the collection of unprocessed materials or composed products is done by automated guided vehicles, which has an important role in the movement of these competitive conditions. The control and speed of production and storage retrieval systems is done by means of human operated forklifts and hence the stock data management are more difficult. The sensing capacity of the system is very poor. The existing method is unable to find the present materials in the storage area. The storing and delivery time of the system is very low and some errors are created by human work.
