automatic liquid filling machine

Project Title

automatic liquid filling machine

Project Area of Specialization Mechanical EngineeringProject Summary

Our project is to design automatic liquid filling machine as in most industries liquid filling machines are not completely automatic and quite expensive to install. We are using mechanical components in the design like nozzle, compressor, gaskets along with mechanisms like Geneva mechanism and Cam-follower mechanism. Pressure difference technique will be used to fill the bottle and remove extra water from the bottle. Compressor will generate vacuum first in the overflow bottle and then in the bottle to be filled and due to pressure difference water will flow from water reservoir to the bottle and then extra water will flow towards overflow bottle again by pressure difference. Bottles will be placed in a tray and tray will move downward after filling a certain bottle where it will be rotated so the next bottle will be in position of the nozzle and then it will raise up to the nozzle and filling will start. We are using cam follower to raise and descend the tray and Geneva mechanism to rotate the tray. In dwell time of Geneva mechanism tray will raise, bottle will be filled and tray will descend down. In first dwell of cam follower mechanism bottle will be filled and in second dwell tray will be rotated. Mostly in industries where liquid filling machines are used complex changes are required to change volume flow rate when different sized bottles are used therefore we are using pressure difference technique to avoid these changes that reduce production rate by consuming time. To make the prototype financially effective we are using used medicine bottles as the containers to be filled with liquid.

Project Objectives

Basic objective of our project was to develop a liquid filling automatic machine that would operate on phenomena of pressure difference and would be simple to operate as current machines operated by industry are not fully automatic usually that leads to reduce rate of production. We aimed to develop a machine that would not require complex hardware and programming changes unlike the status quo. We aim to develop a machine using mechanical components like nozzles, compressors and seals that would operate on mechanical mechanisms like Geneva mechanism, cam mechanism and pressure difference technique. Using these techniques, we can change volume flow rate by simply changing pressure difference generated by compressor. Initially we aim to create a prototype of machine so that we can look over the working and improve it according to our requirements and observations and the dynamics of industry. We also aim to develop a machine manual that would assist the operator regarding working of machine and also provide standard values of pressure difference required to fill a certain volume.

Project Implementation Method

The practical implementation of our project is very diverse. Initial prototype would be based on the idea of filling carbonated drinks such as we have seen in Pepsi co and coca cola. Our project can be used in these above-mentioned companies and due to its low cost, it can also be used by smaller local companies thus giving them more room for improvement of quality within a given cost. Apart from this, our machine is also useable in oil companies where barrels are to be filled or by cooking oil companies at their bottling site. Only difference in above case would be of grade of mechanical parts as they are supposed to work with the liquids that are not going to damage them of effect their working or another difference that would be there will be of pressure difference required to be generated for same volumes to be filled, for this purpose we will create separate manuals for ease of operation and improved versatility.

Benefits of the Project

Basic benefit of our project is more of industrial rather than for community or some other group. The basic benefit that we kept in mind was inaccurate filling of liquid in bottles which sometimes costed large firms millions of dollars once produced in bulk if the machine was filling slightly more than required and in other case it led to bad name in market when it was filling slightly less than the displayed volume. To encounter this, we developed a system that is more accurate so that we can reduce losses on both ends. Apart from this our project will lead to cheaper filling of bottles at almost same rate if not more thus saving millions of rupees which can be later be diverted to be used in other purposes. We have developed a system that has hardware that can be changed easily in case a company decides to use another liquid to fill in machine or they want to fill bottles of different size/design/volume. Volume filled can be changed by simply changing the pressure difference generated by compressor, nothing else will be required to achieve this purpose. This saved time can be used as a production thus enhancing production rate and thus efficiency of labor and machine both.

Technical Details of Final Deliverable

Liquid filling machine used in industry are mostly not automatic and require complex change in hardware and programming if you want to vary volume flow rate or total volume filled in each succession. Hence our aim was to design a machine using mechanical components like compressors, nozzles and seals; we used mechanical mechanism like Geneva mechanism and cam mechanism to develop a machine which can vary volume flow rate and hence volume filled in each bottle by simply adjusting pressure difference generated by compressor. Standard calculations for each volume will be given in manuals provided with machines. Another aim of this project is to provide ease of operation and maintenance, in case any parts need to be changed, it can be changed with bare minimum technical training and will not require as such specialized labor to change it. One of the aims of our project is to implement all mechanism mentioned above successfully; Geneva mechanism is used to rotate the tray and cam mechanism is used to raise the tray so that bottle can come in contact with the nozzle and a proper seal is ensured so that pressure difference generated by the compressor is not lost due to leakage in seal thus reducing the volume filled as compared to preset value. Apart from the above-mentioned deliverables we also provided with mathematical calculations for technical parts along with proper analysis on software so that operation of machine is easier to understand and adjust according to the needs of individual firms.
