1. Graphical analysis of channel shaped
components feeding on a vibratory bowl feeder

2. What are vibratory bowl
feeders?
 Vibratory bowl feeders are the universal type
feeders used to feed small parts on assembly line
in required quantity and in desired orientation.

3. feeder

5. Basic working of the feeder
 The system consists of a vibratory bowl feeder
and a transformer. It converts Electro-
magnetically produced vibrations into mechanical
vibrations.
 It consists of a bowl mounted on a base by three
inclined leaf springs. An electro magnet is fixed
rigidly to the top spring holder and bowl and the
vibrations are transferred to the spiral conveying
track of the bowl.
 The transformer consists of a frequency selector
ranging from 0-100 Hz. Hence this became one
of the three parameters for experimentation.

6. Objective
 Presently, graphical analysis of channel shaped
sheet metal components on the feeder.
 Workpiece-

7. Objective
 Then the behavior of parts was observed in the
feeder and accordingly the path of the feeder was
modified to get the required orientation of the
work pieces.
 Selected orientation

8. Selected Parameters and their
range
 Frequency of operation: 52-61 Hz
 Part Population: 75-300
 Part Length: 20-40mm

9. Procedure
 Experiment was performed based on these
parameters and observations were taken.
 The experiment was carried out by taking one
factor at a time.
 Feed Rate V/s different parameters graphs were
plotted
 Effects due to all the three on feed rate were
studied.

13. CONCLUSION
On the basis of graphical analysis done by
experimentation following are the conclusions
drawn:
 Effect of frequency on feed rate- In general it is
seen that with increase in frequency, the feed rate
increases. However the highest feed rate was
obtained at 55 Hz.
 Effect of part population on feed rate-Feed rate
increases for increasing population and the best
feed rate contains part population of 300.
 Effect of part length- It is also increasing with
increasing part length. And the highest feed rate
is achieved at part length of 20mm.
