Previously, dishes were manually fed and retrieved into the machine but it was to be automated using air cylinders to reduce cycle time and labor costs.
Initially, the dishes deviated in position from the suction pad by the impact on the YZ air cylinders which resulted in shutting down the machine and production did not increase.
It was decided to consider using electric actuators instead.
A system combining a two slider rotary nut NS actuator as the Y-axis, and RCP4-SA5C actuators as the Z-axes was considered.
The NS can operate without having the sliders collide since they can move independently on the same axis. It is also able to accelerate and decelerate faster thus allowing the cycle time to be shortened and stop without impact.

A retaining ring, called the circlip, is used to assemble the pin that connects the connecting rod and the piston of the engine parts.
Since the circlip is manually assembled, variations will occur. If the circlip is improperly seated in the groove, it becomes a problem in that it ends up falling off later.
The ROBO Cylinder RCP3-TA4R table type was adopted into an automatic inspection machine after the manual assembly which eliminated the circlip failure.
The circlip is now inspected for being at the correct position at the assembly stage. It can be double checked using the zone output signal and the position complete output signal to confirm whether the circlip is positioned within the tolerance range.
The ROBO Cylinder has been adopted into a machine to automatically knead buckwheat flour.
Previously, a rack and pinion mechanism along with a gear reduction general purpose motor was used for the up and down kneading motion of the flour. However, since the buckwheat flour is very viscous, this not only caused a problem with the motor and gear reducer but also broke teeth in the rack which resulted in a lack of pressing force.
By changing to ROBO Cylinders, this solved the problem of gear teeth being broken by eliminating the gear rack, and it also made possible an improvement in the pressing force. The flour was kneaded with a stronger force which lead to improved quality and reduced the cycle time.
Furthermore, compared to the conventional machine, the structure of the machine became simpler by reducing wiring and programming efforts, thus a significant cost reduction was also realized.
