Bags and pouches can be difficult to grip, especially when the contents create an uneven surface because of their shape, hardness, or frozen condition. Although carbon graphite robot arms powered by dynamic servos can achieve incredible speeds, they also generate enough g-force to knock the bag from the gripper.
With more than 40 years of case packing experience, Edson Packaging Machinery engineers applied their expertise to a new compact robotic case packing system that operates at high speed and uses the flexible 2-axis delta robot system. Along with the robot, the engineers also combined software, servos, and advanced vacuum and gripper systems into the packaging system.
Edson selected Elau to supply the 2-axis delta arm. The delta robot differs visibly from most case packers with its sleek, uncluttered work envelope. It is built of a stiff, lightweight, durable carbon fiber composite for the same reason that high performance aerospace structures use this material. It is easy to sanitize and clean, and is fully enclosed for clean room operation. A stainless steel version is also available.
Elauâ€šÃ¢â‚¬â„¢s software control program limits the robot armâ€šÃ¢â‚¬â„¢s acceleration without loosing control, plus it reduces programming for the engineers. By smoothing arm operation, it also makes for gentler product handling and longer arm life.
In the software program, a software object takes conventional servo-driven parameters for packaging machines and automatically transforms them into the complex kinematic algorithms robots require to synchronize all axes about the tip of the robot arm.The rest of the electrical system is supplied by Schneider Electricâ€šÃ¢â‚¬â„¢s packaging technology and solutions center (PTASC).
