Leak Detection System
Beyond Bottles: This same in-line inspection solution can be used for soft pouch packaging such as contact lenses or coffee "pods."
What is a Soft-Land™?
The Soft-Land™ is a patented unique routine which allows the actuator rod to land on the surface of a container 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 container.
SMAC STACK is ideal for eject applications. SMAC STACK combines multiple functions into a single assembly by stacking various control functions together. SMAC STACK is a cost effective solution for automating multiple axes with a built-in controller option via CANopen, Ethernet/IP and EtherCAT. It simplifies installation and reduces cabling of multi-actuators. It allows easy, quick exchange of units, which reduces down time. Easy to customize to fit application requirements.

Product used: LAL95 series linear
Problem: The current method for leak detect has been tapping on the top of lid and sensing the pressure. This is difficult technique with low accuracy.
Solution: Sense side of bottle, push with specific force and determining the movement to determine pressure in bottle. This is primarily in bottles pressurized by nitrogen filled bottles (soda, etc) where they are more solid. If there is a leak the spring back is greater. The cycle rate is 20 Hz. Since the SMAC actuator can sense the surface, apply programmable force and monitor position of movement we are a game changing solution, much more accurate than vacuum decay / pressure decay leak testing.
