Project History

Sleeve Ring Assembly Machine
– Human operator
– Would benefit from automation

Project Presented
– Lubricate
– Load
Requirements

Customer
– Load two types of ring seals
– Reject defective rings
– Operate at reasonable rate
– Jam infrequently
– Machine cost must be reasonable

Engineering
– Quantifies customer requirements
Targets

Engineering
– Load Teflon and O-rings with varying
diameter of 1 +/- 0.25 inches.
– Ensure 100% of twisted rings do not
enter SRAM
– 120 sleeves assembled per hour
– Zero jams per shift
– $22,000 budget
The Inspiration


Challenge of
loading four vertical
rings at same time
“The Pringles Can”
– Five plates
– Four spring loaded
flaps
– Arms release and
reset
Overall Process
Sub-systems

Greenfield Feeders,
Inc.
– Vibratory bowl,
dampening stand,
and hopper

Miltec
– Conveyor belt,
lubrication module

APF

Custom bowl allows for 1,000 rings to be
stored
– Allows for longer autonomous run time
– Or more sleeves per hour at faster rate

Proper part loading
– Set up and jam clearing times below target values
– Zero jams per shift (statistically insignificant)

Total cost of $16,800
Conclusion




Reliable mechanical system
Meets or exceeds all targets
Affordable cost
Increase in efficiency
