Effect
Cycle Time reduced, Choco Tei (Short Stoppage of Production Line)
ELECYLINDER Rod type (EC-R7)
Air conditioned factory floor
1 Equipment overview [Application]
A device for opening and closing the hatch located at the process where cardboard boxes are conveyed to the shipping platform.
There are five conveyor lines in this factory, using five hatches in total.

2 Disadvantages of air cylinders
Disadvantage ❶ Impact at the upper and lower ends damaged the acrylic panels of the hatches,
which required annual replacement.
Disadvantage ❷ Due to production line HVAC and cycle time issues, the open/close time could not be reduced.
3 Improvement with ELECYLINDER implementation ˜Adjustment of velocity achieved fast and smooth open/close
motion and eliminated impact damage to the hatches.
4 Cost reductions achieved with improvement
Hatch panel replacement was no longer required, reducing costs as follows.
Hatch panel cost: $300 per piece
Replacement operation cost: $36 per replacement
Total for five production lines: ($300 + $36) × 5 = $1,680
Cost reduction of $1,680 per year has been achieved.
