Motorizing the removal of defective products made high speed possible and lowered costs.
[Issues Until Now]
An air cylinder was used for the movement of the plate that removes defective products.
Adjusting air pressure was difficult, and removal speed was unstable. This caused defective products to get stuck on the entry of the conveyor when the speed became low.
The speed of the removal conveyor was set slow to ensure the removal of defective products.
[Improvement with Motorization]
Removal speed was stabilized. This prevented defective items from getting caught at the entrance of the removal conveyor.
The speed of the removal conveyor was raised.
[Improvement Results]
Line speedincreased by 40%
Production per day increased from 15,000 units to 21,000 units (1 line)
A small and thin type Robo Cylinder® and a MEC controller have been adopted for labeling glass bottles for beverages.
When the bottle is placed on top of rollers, the rollers rotate in sync with the feeding of the label.
As the label is fed, it is transferred from the paper onto the bottle. The label is fixed by pressing down on it with Robo Cylinder®.
An Air cylinder was considered, but the equipment was motorized so that it could be used in places without compressed air.
Robo Cylinder® can use the same input/output circuit as an air cylinder, and as construction without a PLC was possible, the equipment was produced at a low price.
Shampoo Filling Equipment Cut the operating hours by 18% by being able to change the speed during use.
1. Increased the discharge flow rate to shorten the fill time.
2. Achieved only 0.2 minute of changeover time.
Sequential Feeder Non-woven Fabric Punching Line Reliable movements resulted in a defective rate of 0%.
1. Significantly reduced the defect rate.
2. ROBO Cylinders have a service life of 10 years or longer.
