Beckhoff at Motek 2011: Hall 9, Booth 9108
TwinCAT software ensures exact synchronisation in delta robots from KOCH Pac-Systeme GmbH
Handling technology: PLC, robotics and Motion Control on one platform

Beckhoff is presenting its automation solutions for assembly and handling technology at the Motek 2011. The live application of the KRH-D delta robot from KOCH Pac-Systeme GmbH at the Beckhoff trade fair booth provides an insight into the capabilities of the PC- and EtherCAT-based control technology. Modern, high-performance PC technology in combination with high-speed Ethernet communication integrates robotics on a single hardware and software platform alongside PLC, Motion Control and measurement technology. This means that a proprietary controller can be omitted, communication is simplified and, hence, the productivity of the plant is increased.

With the delta robot KRH-D KOCH Pac-Systeme GmbH has created an overall concept for versatile handling solutions with highest picking performances. The specialist for packaging machines from the Black Forest provides a pick and place solution with flexible working area up to Ø 1,200 mm and extreme accelerations and velocities. This is possible due to lightweight construction with CFRP structure elements. The resulting gain of time and saving of costs with product feeding into packaging machines are only two of the many advantages of the state-of-the-art KOCH robot KRH-D. This robot can be integrated into any KOCH packaging machine and also can be used separately as stand-alone solution.

KOCH uses the TwinCAT Kinematic Transformation software library based on TwinCAT NC I and G-code (DIN 66025) to control the delta robot. It was developed by Beckhoff especially for robot kinematics, e.g. for pick-and-place tasks. Depending on the application, the delta robot in the insertion zone must pick up the non-orientated item to be packed from a continuously running conveyor belt and place it into the blister pack. The necessary synchronisation to the conveyor belt for picking up and setting down workpieces is enabled by the TwinCAT ‘Flying Saw’ and ‘Cam Plate’ libraries. The position of the item to be packed is precisely detected by an image processing system (Conveyor Tracking). TwinCAT processes the imported image data so that the robot can accurately grasp the released item to be packed and place it into the blister. Together with the Beckhoff EtherCAT terminals, the EtherCAT servo drives and servo motors ensure the dynamic and reliable control of the delta robot.

On the KOCH Pac-Systeme GmbH:

KOCH Pac-Systeme GmbH is a successfully expanding medium-sized company with 200 employees worldwide. At the main location in Pfalzgrafenweiler KOCH develops, constructs and sells customized machines and lines – from the individual machine to the complex packaging line. Since July, 2006 KOCH Pac-Systeme GmbH is a member of the Uhlmann Group and with that provides a further competence of special packaging machines in the pharmaceutical branch. Classical branches for packaging machines manufactured by KOCH are established in the sectors non-food, medical care, body care and cosmetics. With that KOCH Pac-Systeme GmbH provides packaging solutions right down the line: from the small blister sealing machine to the complex packaging line including robot, product handling and end-of-line packaging.
