Abstract - Vibratory bowl feeders are used to feed small
parts into various stations. At each station parts will be rejected, accepted or send for the further machining processes depending upon the orientation of the part. This analysis was for Unity Bushes & Tools Company who was looking to increase the production by increasing the part feed rate by using vibratory bowl feeder. The Scope of this analysis is to produce detailed analysis of the vibration system required to move the parts through the system and show how different spring configurations would affect the flow of the part through the system. From this analysis, we are able in to increase production and reliability of the system. Key Words: vibratory Bowl feeder, feeding processes, automation in feeding, small parts feeding mechanism
1. INTODUCTION This work focused on real time application of vibratory feeder approached us to improve the function of the bowl feeder in order to speed up the cycle time on the grinding machine . This will increase the productivity on the line . A vibratory feeder is an instrument that uses vibration to "feed" material to a process or machine. Vibratory feeders use both vibration and gravity to move material. Gravity is used to determine the direction, either down, or down and to a side, and then vibration is used to move the material. They are mainly used to transport a large number of smaller objects. Versatile and rugged vibratory bowl feeders will be used for automatic feeding of small to large and differently shaped industrial parts. This technique is old but still commonly used automation machine available by changing the parameters as per the requirements for aligning and feeding machine parts, electronic parts, plastic parts, chemicals, metallic parts, glass vials, pharmaceuticals, foods, miscellaneous goods etc. Standard and custom designs, vibratory bowl feeders will be useful to various industrial sectors for automating high-speed production lines and assembly systems. With these easy-to-use and high-performing partfeeding machines, customers from varied industrial sectors have achieved lower error rates, less power consumption, better profits, better rates of efficiency and less dependency on manpower. Vibratory bowl feeder is ideal tool to get the Š 2017, IRJET

required, oriented output of the components at specific feed rate. In this project we have designed a vibratory bowl feeder for feeding dowel pins to the grinding machine to increase production by increasing part feeding rate by using vibratory bowl feeder. Designing proper bowl feeder for specific part feeding application is critical. Variety of factors such as part size and geometry, orientation required, feed rate, direction of output (clockwise, anti-clockwise) are just a few factors that affect the bowl design. The vibration test is carried out for confirmation of the work. We have design the bowl to suit the requirement of Unity Bushes & Tools Co. Pune.Finally, we have made vibratory bowl feeder as per the company requirements and verified it by doing the actual operation on grinding machine with satisfactory performance.
1.1 OBJECTIVE
Our aim in this project is to design vibratory bowl feeder that would replace or can be an alternate the manual feeding to centre less grinding machine used in feeding of small components in various work stations. Vibratory feeders use both vibration and gravity to move material. Gravity is used to determine the direction, either down, or down and to a side, and then vibration is used to move the material.
1.2 SCOPE It has been difficult to work manually in feeding of small parts like dowel pins , small nuts , castle nuts etc. By providing feeding mechanism it becomes easy to use by the operator as well as it gives high performing part feeding mechanism. This automation is beneficial for industrial sector to achieve lower error rates and less power consumption, better profits, better rate of efficiency and less dependency of man power.
2. METHODOLOGY
The electromagnetic parts feeder is a two-mass system. Mass one consists of the heavy base and rubber isolator feet, as well as the electromagnet. Mass two consists of the bowl mounting plate (often called the cross arm), the armature, and the bowl. The two masses are connected through four sets of leaf springs.
