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.

      Problems  

    ➤ 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The air cylinder has been replaced by an ELECYLINDER.
 

  Improvements  

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

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

  Effects     (Condition: Labor cost US$12/hr, Annual operation 240 days.)

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.
