Cutting Cords to Variable Specified Lengths – CT-Effects Application Example
[ Robot/Electric Actuators ]


  • [Issues until now]

    – Air cylinders were used to feed a cord to a specified length.

    – It took time to manually adjust the stopper position each time the product type was changed. (About 5 minutes per changeover = 1 hour/day)

    – It was difficult to cut the correct length, causing workers to repeatedly inspect and adjust the cutting.

  • [Improved with Motorization]

    – Manually adjusting the stopper position was totally eliminated. Adjustments are now done by entering the feed amount on a touch panel. Manual changeovers are a thing of the past.

    – Using a value command function in the ROBO Cylinder made it easy to cut lengths of specified varieties. The manual labor for adjustments was significantly reduced.

    [Improvement Results]

    – Production was increased from 7 hours per day to 8 hours.

    – Reducing the number of steps also reduced labor costs.

Reduced man-hours needed for:
– changeover time: 60 minutes/day
– cut inspection and adjustment time: 120 minutes/day
→ Total of 3 hours/day
(Annual Example)
– Labor Time of 3 hours/day (times 250 days/year)
– 3 hours X $10 X 250 days
If labor costs $10/hour
→ Annual Savings of $7,500

Electricity costs reduced with motorization

(Example) Work load: 3kg, Moving distance: 200m
Cycle time: 3 sec. One-day running time: 8 hours

Annual operation days: 250 days
Unit Price: (Air) $0.24/m3 (Electric) $0.15/KWH

〈 Annual Electricity Costs 〉Approximately 95% reduced
Air Cylinder$117.67/year
(Cylinder inner diameter φ25mm)
Electric Cylinder$5.67/year
