Quality inspection device
Defective product discharge line
A device that performs visual inspection of toilet rolls
and extracts dirty or cracked defective products to
the discharging conveyor. The device returns to the
standby position after pushing defects onto the discharging conveyor.
2 Disadvantages of air cylinders
Disadvantage ❶ Velocity could not be set high enough
due to the risk of workpieces being flung off the conveyor at high velocity. Disadvantage ❷ Shipping line conveyor was operated at low speed to match the discharging speed.
3 Improvement with ELECYLINDER implementation
˜Smooth acceleration and deceleration even at high velocity means no more workpiece overshoot.
Speed of discharge: Air cylinders 4.2 s ELECYLINDER 3.0 s ˜Speed of shipping line conveyor was increased.
Shipping line conveyor speed: Air cylinders 4.2m/min ELECYLINDER 6m/min
4 Cost reductions achieved with improvement
Production volume per hour increased by 40%
(Conventional) 1,500 units"(Improved) 2,100 units = Productivity improved by 600 units/day.
Production volume per day: 15,000
(Originally) 10 hours"(Improvement) 7.1 hours = Reduction of 2.9 hours per day.
Labor costs: $18 per hour per operator with 230 working days per year
2.9 hours x $18 x 230 days = $12,000
Cost reduction of $12,000 per year has been achieved.
