This process carries a pair of parts, and then does spot welding in 3 locations per part. Until now, because it was done manually, more workers were needed to increase production to meet customer demand. In addition, since the project of high-mix low-volume production has been increasing in recent years, the welding process was automated using our ROBO Cylinders this time. It cost $12,000 ($6,000 / unit × 2 units) to build the two units, but it was amortized over 7.5 months.
(Personnel Expenses was calculated at $10 / hour)
After changing to ROBO Cylinder
Due to the manual labor, large differences had come out in production volume and quality depending on the workers. But with the result of the automation, since the parts stop at the same location repeatedly for welding, the quality is stable, and the defects became almost zero.
Compared to the manual labor, cycle time is improved, and production has increased significantly.
Since the worker was now only responsible for the placement and removal of the parts, and they can now handle the two units alone, the labor cost is now half.
In a system for performing the alignment of some resin blocks, the ROBO Cylinder was adopted. The company’s products include designer plates to be used on the floor of a house by bonding resin blocks.
Previously, an air cylinder was used, this was changed to ROBO Cylinder which improved the cycle time and reduced the occurrence of Choco-Tei events.
When air cylinder was used
Because the resin blocks were misaligned by the impact of the air cylinder stop, they were operating it at a reduced speed. However, Choco-Tei was still occurring about 10 times a day because of the misalignment due to unstable speed. To rearrange the resin block and to recover from Choco-Tei, it took about 1 minute.
After changing to ROBO Cylinder
By replacing air cylinder to ROBO Cylinder, and adjusting the pressing force and acceleration/deceleration, they could increase the operating speed while minimizing the impact at the time of stop. In addition, Choco-Tei was reduced to near zero.
