Industrial Applications

1. High-Precision Rotary Sorting Station for Packaging

Utilizes the Festo DSM-25-270-CC-A-B to rotate and divert packaged products onto separate conveyor lines. The integrated shock absorbers at both ends smoothly decelerate the load, preventing product damage or jarring at the end of the pneumatic stroke.

Problem Solved

Eliminates product bounce and misalignment during high-speed conveyor sorting. The 0.03 kgm² permissible mass moment of inertia and built-in shock absorbers ensure stable handling of medium-weight items, while the 0.1 degree repetition accuracy guarantees exact alignment with the outfeed conveyors.

Shock absorption0.1 deg repetition accuracyDouble-acting vane0.03 kgm² inertia

2. Automated Part Orientation in Electronic Assembly

Integrates the rotary actuator into an assembly cell to flip or orient electronic housings before final screw insertion. The actuator's wide and adjustable rotation range is configured to align asymmetrical parts perfectly into their mating fixtures.

Problem Solved

Solves the need for precise and flexible angular orientation of parts prior to automated assembly. The adjustable swivel angle up to 246 degrees handles complex geometry positioning, and the 5 Nm theoretical torque at 6 bar provides ample force to smoothly rotate the custom tooling and part, accommodating axial loads up to 50 N.

3. Pneumatic End-of-Arm Tooling (EOAT) Wrist for Gantry Robots

Acts as a compact wrist joint on a gantry robot's end effector, providing robust rotational freedom to pick and place parts at varying angles during automated CNC machine tending operations.

Problem Solved

Overcomes the payload limitations of lightweight gantry arms by providing a high power-to-weight ratio. Weighing only 710 g, it minimizes the end-of-arm mass while delivering reliable, repetitive rotary motion at a 1 Hz maximum frequency. The position detection via proximity switch allows seamless feedback to the machine's PLC.
