It can only fill approximately one bottle at a time. The process can be efficiently used in water fillingsystem. These types of fluids are handled mainly by the solenoid valve and nozzle used. So the range of fluid types is not so wide. Positioning the solenoid valve is a critical issue and proper care is needed. Another disadvantage is, no proper guidance for the bottles to move. And making the system to cause imbalance vibration. This system is constrained by height (max 6.6’’ inch) of the bottle of a specific volume.
A Programmable Logic Controller, PLC or Programmable 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. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory. A PLC is an example of a hard real time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result.
Automation is one of successful field in today’s world and it has become the backbone of control engineering. Automation plays an increasingly important role in the world economy and in daily experience. The goal is to provide plant operators and engineers the tools to monitor and control their plant more efficiently. Automation is nothing but taking a system or process and making it automatic by eliminating human work as much as possible. Mixing of liquids is a common process in the paint industry; medical industry; chemical industry; pharmaceutical industry etc. The most important step in mixing the liquid is defining the accurate proportion of constituent liquid element; which can be effectively and accurately performed with the help of machinery without manual intervention. This system is designed for automated level control; liquid mixing and filling of bottles. The system is designed for filling the mixture of two liquids in equal proportion. It consists of three sub system namely level controller; liquid mixer and bottle filler. The entire process is controlled and automated with the help of PLC. PLCs are widely used in automation industry and process control systems due to its ability for being user programmable. AutomaticLiquid level controller is designed to automate, monitor and control liquid level in the tank with the aim to reducing cost and human intervention along with prevention of industrial accidents due to overflowing of the tank. Level controllers are used for different industries as well as domestic household purpose to automatically control the operation of motor thereby avoiding wastage of resources. Automated liquid mixer performs mixing of different liquid in predetermined proportions. The input to the control valve is given from the PLC. According to the ladder program the valve will works and controls it‘s flow.

Most industrial processes require objects or substances to be moved from one location to another, or a force to be applied to hold, shape or compress a product. Such activities are performed by Prime Movers; the workhorses of manufacturing industries. In many locations all prime movers are electrical. Rotary motions can be provided by simple motors, and linear motion can be obtained from rotary motion by devices such as screw jacks or rack and pinions. Where a pure force or a short linear stroke is required a solenoid may be used (although there are limits to the force that can be obtained by this means). Electrical devices are not however, the only means of providing prime movers. Enclosed fluids (both liquids and gases) can also be used to convey energy from one location to another and, consequently, to produce rotary or linear motion or apply a force. Fluid based systems using liquids as transmission media are called hydraulic systems. Gas- based systems are called Pneumatic systems. The most common gas is simply compressed air. Although nitrogen is occasionally used
In this paper a Programmable Logic Controller is designed with the ARM7 LPC2378 controller platform with full software support of LabVIEW. In addidtion to this three systems automatic bottle fillingsystem, automatic level control system and alarm annunciator system were discussed and their system automation performed using the embedded PLC. These systems were designed and tested on the embedded PLC. FBD is found to be more user friendly than any other language of the IEC 61131-3 standard. The direct connections of the input and output ports to function blocks in FBD makes it easy to use and understand. The tedious task of addressing the elements is thus eliminated. Using LabVIEW for programming the embedded PLC has saved the efforts of programming the ARM processor in embedded C language.Programming the embedded PLC has thus become user friendly. Embedded PLC is found to be less costly to other PLC’s. As the processor board has all the IO ports available on it there will be very minor cost increase if user needs to increase the number of IO.
Industry automation becomes a spacious field in manufacturing which had important role in an extensive range of industries beyond manufacturing [1,2]. Nowadays the rapid development of manufacturing and technology has led to an increase in production level.. Where the production managers are faced challenged to reduce the cost of the product with maintaining product quality within a time framework and due to the increased demand for on consumer products so competition among manufacturing companies has become dependent on cost, accuracy, time, and quality for that the key to such a problem is the use of integrated processes in the industry. Programmable logic controller(PLC) is extensively used in industrial automation and it act as a brain in industry application. PLCs in the industrial field are utilized to control a certain process in order to get better performance and higher accuracy to give more production in an efficient manner. This paper present, design and implementation water filling machine system for different sized bottles by using PLC.

In this new technological era automation has always played a major role in the industries in developing the productivity and reducing human effort beyond our expectation. Automation is the combination use of control system and technology to reduce human effort. Automation has outpaced mechanization where humans work with hand and use of muscular strength to operate the machinery. It has not only played an important role in the industrial world but also an increasingly important role in the developing the world economy. One of the most important applications of automation is in the soft drink and other beverage industries, where a measured amount of particular liquid is to be filled in bottles. This can prove to be a difficult job without having an automated system capable of doing it. Today the beverage industry are moving towards complete automated solution starting from manufacturing, quality testing control, monitoring productivity, shipping, and to shipment delivery tracking. Our research is an application of automated system which will reduce human effort in beverage filing in the manufacturing unit. We have developed a bottle filling automated system with specific quantity. This automated system is controlled and operated using a PLC (Programmable Logic Controller) and is monitored using SCADA (Supervisory Control and Data Acquisition).
This work has a complete application of mechanization. These processes are controlled by PLC and monitored by using SCADA. PLC and SCADA are the important part of the bottle filling the system. As the system controlled according to the programmed PLC and SCADA is used to monitor the process in system. This system utilizes a start/stop control of the engine when we on the switch then motor gets started. Bottles are kept in conveyor line which will be attached to the motor. When a motor is switched on then conveyor will start moving. At the point when bottle goes under the tank then a sensor senses the bottle and the valve open for the specific time period as programmed in the programming for that time the liquid filled into the bottle. The rate gets affected by the position of the valve. The required filling operation depends on user categorized volume through which user can pick the volume of fluid to be filled.

Abstract— Cutting is a compressive and shearing phenomenon, where cutting a materials like paper, timber, pipes to the required length in any manufacturing industry is the initial step. Increasing in Global competition and technological advances are forcing manufactures designers and engineers rapidly produce strategies decreasing products development cost and time. Manufactures who exit at a same time have the option of selecting optimum technologies or processes to coincide with their manufacturing surrounding. The main idea of this work is to design a prototype model for automating the cutting process for varying length in continuous cutting process with reduced time and cost which may applicable in industry. Programmable Logic controller (PLC) and Human Machine Interface (HMI) is used to propose new approach, HMI is designed to enter the values like length, rpm, number of counts and HMI is connected to PLC by RS485 serial communication protocol. PLC is programmed to control the servo motor where entered values are converted to pulses and when targeted length is reached PLC will actuate pneumatic press to cut the paper to solve the problem of continuous cutting process for varying length.
The pneumatic circuit of automatic stamping machine is as shown in the figure 2. It consists of 3 cylinders which is controlled by the DC valves as shown in the figure. The inductive sensors sense the extended and retarded positions of the cylinders. The sensors sense the cylinder position and send the signal to the PLC. The PLC executes the sequential program and activates the required solenoid valve accordingly. The ladder program of the PLC is similar to that of the electronic circuit as shown in the figure 4.2. It consists of 6 inputs and 4 outputs. S1 & S2 are the input signals from the clamping cylinder and Y1 is the output from the PLC that activates the clamping cylinder. The cylinder is controlled by a 3\2 way solenoid actuated spring return DCV .B1 & B2 are the input signals from the stamping cylinder. Y2 is the output from the PLC to activate the stamping cylinder. Y3 is the output signal to retard the stamping cylinder to its home position. There are to solenoids provided to the stamping cylinder to ensure more control over the stamping operation. The cylinder is controlled by a 5\2 way double solenoid DCV
of (4-20) mA is sent to the DAQ in which ADC converts the analog data to digital data and feed it to the Personal computer. The Personal computer acts as the controller and data logger. The DAC module of the DAQ converts this manipulated variable to analog form into 4-20 mA current signals. The I/P converter converts the current signal to pressure in the range of (3- 15) psi, which regulates the flow of water into the conical tank based on the outflow rate of the tank.
As we know that one programming device, such as a personal computer or a laptop is necessary to interface with the PLC. We need a programming device connected to the PLC. Programming devices helps us to enter the required program/commands into the PLC memory and troubleshoot the PLC ladder logic program. The program is entered in the form of relay ladder logic and is responsible to check the operation sequence.
In India, rag pickers play an important role in the collecting ,disposing of urban solid waste. This process has its limitation and it was time consuming as well .Rag pickers and conservancy staff have higher morbidity due to infections of skin, respiratory, gastrointestinal tract and multisystem allergic disorders, in addition to a high prevalence of bites of rodents, dogs and other vermin.this system is still at large in most parts of india .also there was no emphasis on waste segregation ,so segregating recyclable items from amongst other became a tedious task.
Laboratory experiments are the most important part of a robotics education, since students can apply and verify in practice the theoretical knowledge acqui- red during lectures [2-6]. One of the aims in robotic education, therefore, is to teach the techniques and possible challenges of theoretically-based design me- thods when applied in practice. Experimental study is the most important part of robotic education, but expe- rimental studies can be conducted using different methods. One of them is the traditional method. Tradi- tional experimental studies cover any method that involves conducting experiments in a real, physical laboratory at specific time. In this type study, students must be present in the laboratory during the ex- perimental study period and all experiments must be

The preprocessing is a primary step to load the text into the proposed system and involves cleaning the noisy text containing grammatical and typographical errors. The major problem in text summarization is that the size of the document is not well known. Thus each word in the documents wasrepresented by the terms in the vector space model, which causes the number of dimensions to be too high for the text summarization algorithms. This preprocessing method plays a vital role in reducing the number of dimensions passed to the text summarization process. In this paper, the followed pre-processing methods were applied, namely, Removal of Stop Words, Punctuation Removal, Removal of Extra White Spaces, Word Stemming, Key Phrase Identification, Sentence Segmentation and Tokenization.
