Caps Stuck During Transfer
Caps are charged with static electricity by repeated friction and separation caused by the vibration of the feeder bowl. A Coulomb force works on the charged caps to make them cling to the bowl or chute of the feeder bowl.
This Coulomb force prevents the movement of the caps and they become stuck.
Conventional countermeasures
Handled by workers
- Labor costs are high.
- Workers cannot constantly address the problem, so the operating ratio decreases.
Countermeasures with static eliminators (ionizers)
The caps do not clog the feeder bowl so the labor of workers addressing the clogging can be reduced.
Improvements and Effects
Words from the worksite
Reduced labor cost for addressing clogging
Labor cost per worker: $20/hour x Working time of 5 minutes x 5 lines x 8 hours x 250 days = $16,700/year
The system can be made flexible to address increased/decreased numbers of lines.
