High Speed & Consistent Bottle Capping

SMAC actuators can provide linear with rotary motion all in one actuator. With these actuators the user can adjust position, force, velocity and torque in all axes, show the different quality check capabilities such as cap height, torque and angle, force required to press in, distance in both linear and rotary traveled, and even check the clicks on child proof / safety caps.

SMAC Advantages for Closure

  • Locate lead in thread location (height & angle)
  • Report seated cap height and angle
  • Report torque or linear force required to seat cap
  • Detect cross threading
  • Detect damages threads
  • Check clicks on child proof / safety caps
  • Easy to use GUI
  • Utilizes SMAC's patented Soft-Land
  • Approximately half the price of competitor linear rotary actuators

Linear Rotary Actuators

The precision Z-theta motion within one small actuator, providing a convenient pick, orient and place. A wide variety of linear rotary actuators are offered with either direct drive or gearbox equipped rotary units.

The vacuum-built-in shaft through the rotary motor is available for some models to prevent dust build-up in the unit. These z-theta actuators can easily be programmed to control force/torque, position and velocity in all axes at the same time with feedback capability. SMAC's unique, patented "Soft-Land" function enables the unit to gently land on a delicate component with a controlled force to avoid damage of both the component and the actuator.

What is a Soft-Land™?

The Soft-Land™ is a patented unique routine which allows the actuator rod or gripper jaw to land on the surface of a component with a low programmed force. It gives extremely accurate sensing of product location or dimensions. This is particularly useful for handling delicate or high value components.

The routine consists of a controlled low force approach in velocity mode, while the position error is constantly monitored. Once contact is made the position error builds up until a pre-programmed figure is reached - resulting in the rod maintaining position on the surface of the component.

  • Gentle touch – as low as 10g
  • Detect objects / obstructions
  • Used in:
    • Capping
    • Pick and place of delicate objects
    • Gauging of fragile or pliant materials
    • Switch / material testing
    • Many, many others

Capping Graphical User Interface (GUI)

User configurable threaded bottle/container capping applications. Detect and report no/obstructed cap. Adjust force and torque, show the different quality check capabilities such as cap height, torque limit, force required to press-in, and even check the clicks on child proof caps.
