Edson debuts delta robot case packer

Edson, specialists in case packing of hard-to-handle flexible packages, introduces an all-new, ELAU-enabled delta robot packer, the RPd 270, at PACK EXPO booth N-4345

Sustainability will drive flexible packaging usage to higher levels than ever. That’s good news for Edson Packaging Machinery. With over 40 years of case packing experience, they thoroughly understand difficult to handle packs. Now they’ve applied that knowledge to a new robotic case packing system launching at PACK EXPO International 2008, booth N-4345.

Edson already offers a line of proven top load, gantry-style robotic case packers that provide fast, gentle handling of flexible and rigid products ranging from personal care to frozen foods.

What makes the new Edson RPd 270 different is its compact, modular, high speed, highly flexible 2-axis delta mechatronic design using ELAU packaging solutions (booth E-6413).

Robotics: the ultimate in mechatronic design

The new delta robot differs visibly from most case packers with a sleek, uncluttered work envelope that holds several practical advantages. It’s easy to sanitize and clean out, is fully enclosed for clean room operation, and provides the hallmark mechanical simplicity of a true mechatronic design. A stainless steel version is also available.

Partnering with Schneider Electric’s packaging specialist, ELAU, Edson has combined ELAU’s purpose-built robotic, automation and servo module technologies with their own vast application knowledge to optimize performance.

Mastering the intricacies of Flexible Packaging

Standup pouches (SUPs), 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 highly dynamic servos can achieve incredible speeds, they can also generate enough g-force to knock the bag from the gripper.

Edson has mastered these and other challenges in classic, multidisciplinary mechatronics fashion – through software, mechanical design, servos and advanced vacuum and gripper systems.

For example, ELAU supplies an exclusive software object that limits the robot arm’s acceleration to the maximum without losing control of the product. It’s not available from other automation suppliers, and it simplified robot programming for Edson’s engineers. By smoothing arm operation, it also makes for gentle product handling and longer arm life.

Technology takes the mystery out of robotics

Likewise, ELAU has taken the mystery out of robot programming through its robotic transformation – a software object that takes the parameters a mechanical engineer would apply to a conventional servo-driven packaging machine and automatically transforms them into the complex kinematic algorithms that robots require to synchronize all axes about the tip of the robot arm.

General automation suppliers have announced robot control capabilities, but due to their underlying architecture they are unable to process fast enough to compete with proprietary robot controls. To deliver the promised performance, therefore, Edson offers its robotic case packer only as an ELAU-enabled system.

The rest of the electrical system is supplied by Schneider Electric’s packaging technology and solutions center (PTASC), for a single source of supply and worldwide support.

Edson has selected ELAU to supply its 2-axis delta arm, a design that’s also purpose-built for packaging applications. It is built of a stiff, lightweight, durable carbon fiber composite for the same reason that high performance aerospace structures use this material.

The 2-axis delta concept offers the reach, payload and efficiency needed for case packing, compared to articulated robots or 3-axis delta pick-and-place robots.

About Edson Packaging Machinery

Edson is a specialist in ‘end packaging’ automation and has served small and Fortune 500 companies on 5 continents, for over 40 years. To achieve this success, Edson develops advanced packaging systems to handle the latest in packaging formats, and offer full ‘end of line’ integrated solutions.

With the focus on sustainable packaging, providing flexible packaging systems is key; however the real level of success is in providing responsive ‘after market’ service for repair, upgrades and modifications to handle new packages. Complementary to the automation itself is Edson’s offer of integrated ancillary equipment, such as conveyors, accumulators, RFID scanners, lane diverters, adaptive motion controls and easy to program interfaces.

World-wide customer support is provided through Edson’s network of regional automation partners, and teamed with ELAU’s factory support centers, users can be confident of fast and competent service.
