WARE HANDLING SERVO MECHANISM SERVO INVERT SERVO TAKE-OUT BDF A.P. PUSHER

WARE HANDLING SERVO MECHANISM BDF, first in the world on the 1992, has designed and implemented in the I.S. Machines the Servo Invert and Take-Out mechanisms with the objective to reduce the defects in the finish and neck area. The result of this engineering program has been the realisation of a new state-of-the-art on the glass technology for the electronic control systems and for the servo mechanisms controlled by brushless servo motors with mathematical interpolation motion profiles.

SERVO INVERT Electric cams with interpolation Sinusoidal acceleration deceleration Process control during the motion Easy set-up with computer or hand terminal Check of end-stroke positions Defects reduction on container finish Productivity increase (constant setup) Reduction of manual adjustments Elimination of hydraulic cushioning Very low energy consumption due to the energy recovery control Main Data Minim.
