This display unit is a nut-rotation type actuator configured for vertical specification, where two independently operating sliders move work parts from one rack to the other installed at different heights.
The nut-rotation type actuator is characterized by its integration of motor and slider. The ball screw is fixed and the nut is rotated to move the actuator. This operating principle also supports a multi-slider mechanism where multiple sliders are installed and operated independently.
The vertically oriented slider comes with a brake. Incorporation of the brake makes it easy to design vertical configurations, which has been difficult with linear servos.
