We would like to share with you this Application Improvement Example.
   Application Example   

Conveyor Transfer Equipment

Equipment Overview

  1. Equipment for transferring between two conveyors. (6,000 boxes/day)
  2. Workpieces are transferred between two conveyors that are located in different levels and changed their directions.

   Before Improvement

  Previous equipment  

➤ A box packed with cakes is transferred on an inclined roller conveyor to the X direction and stops when it makes contact with a stopper.
The air cylinder [A] moves upward to lift the box.
The air cylinder [B] retracts to draw the box in.
The air cylinder [A] moves down to put the box on the lower level conveyor.
➤ The workpieces move on the inclined conveyor to the next process.
The air cylinder [B] moves forward to push out the fork to prepare for the next operation.


    ➤ Due to shock at the time of a stop, the box sometimes dropped out, causing a "choco-tei" (a temporary stop).
    ➤ To recover from a "choco-tei", it takes about 10 minutes for speed adjustment of the air cylinder.
    ➤ "Choco-tei" occurred about 5 times per day: A total of 50 minutes (10 min. x 5 times)/day was spent for recovery.

   After Improvement


  Improved Equipment  

The air cylinder has been replaced by an ELECYLINDER.


Acceleration/speed/deceleration are numerically specified, achieving a smooth and high-speed operations without shock.

"Choco-tei" (a temporary stop) has been eradicated.

  Effects     After replacing an air cylinder with an ELECYLINDER

The working hours has been reduced by 50 minutes per day.
      Recovery time of 50 minutes per day from "choco-tei" (temporary stops) has been eliminated.

Annual saving for labor cost is US $2,400.
      US$12 x 50 minutes (10 min. x 5 times) x 240 days = US$2,400.
      * (Condition: Labor cost US$12/hr, Annual operation 240 days.) Exchange Rate: 1 (USD) = 100 (Japanese Yen)
