Non-contact transfer picking device includes high-grade polymer version
Non-Contact Transfer (NCT) unit from Rexroth is a unique picking device for robotics that operates on the Bernoulli principle, which applies airflow under the device to create a vacuum and lift force between the center and circumference. The line is now expanded to include a high-grade polymer version.
In the last few years, the NCT transfer system has solved many customer problems associated with how to effectively handle materials that are porous, delicate, or have rough or soft surfaces. Now, in addition to the standard aluminum version, the NCT is available in PEEK (Polyetheretherketone), a high-grade polymer. The material expands the potential applications of the NCT to areas where aluminum components are not suitable.
Resistance to chemicals, conventional solvents, acids, salts and oil are properties that make this new version of the NCT an ideal handling component for the packaging and food/beverage industries, the company said. FDA- and EG-approved materials guarantee the safe use of these components, even in direct contact with food products. A low friction coefficient and high resistance to wear ensure a long service life and hygienic handling.
The Rexroth NCT unit provides a solution to many robotic handling challenges where suction cups are not feasible because good contact cannot be made with an object’s surface. Another advantage of the NCT is that a machine with mechanical grippers can be easily converted to the NCT, since it does not require a vacuum generator, unlike other devices that operate using vacuum pressure. The NCT series is available in four sizes accommodating lift capacities up to 2 pounds (0.9 kg) each, and multiple NCTs can be used together for lifting larger weights.
