Loading/unloading loader for processing machines

The production efficiency is improved by 1.16 times

Compared to the equipments in the past by having no short-time breakdown and shortening the cycle time by 1 second.

[Purpose]
After putting the automobile parts flowing on the conveyor into the processing machine and completing the processing, it is used for pick & place to return from the processing machine to the take-out conveyor.

 

[Improvement effect]

≪Before improvement≫
Since the work piece being transported was dropped by the shock when the air cylinder was stopped, the speed of the air cylinder had to be dropped in order to be used. (Facility cycle time including machining time is 7 seconds)

 

≪After improvement≫

By replacing the air cylinder with the electric actuator, it became possible to smoothly accelerate and decelerate without dropping the work piece, and the maximum speed was raised. Therefore, it was possible to shorten the cycle time to 6 seconds. As a result, the production volume per day has become 1.16 times that of the previous model.
