winder machine designed for precision winding of Emergency Locking Retractor
assemblies spring. This machine is quite compact with self-contained control
panels. Error free sequential operation is ensured with the help of positive
feedback interlocks interfaced to the Servo drive. All the co-ordination
movements are performed with the help of pneumatic actuators.
basic structure is fabricated out of Aluminium Extrusion Structure with
suitable enclosures for housing the control and pneumatic panels. This
fixture assembly is capable of holding all type of ELR housing and is
of universal type.
control system is based on industrial standard and highly reliable Servodrive.
It controls the operating sequence of the various operating elements with
the help of feedback signals from various status sensors and switches.
Since the winder a machine is for winding and rewinding the ELR spring
through a preset number of turns, a servo positioning system is employed.
servo positioning system is smart motion control card (i.e.) high-speed
precision closed loop digital servo controls.
