Industrial Robots (articulated-arm, RV-6S series) Small Robots Enhance Production Flexibility
▲Every year the over 70 injection moulding machines at the plant manufacture around 500 different products with production runs between 100,000 and a million units. Robots are now used to handle the delicate moulded parts to prevent expensive wastage. In the past RKT used linear robots for this task, but they were slow and inflexible and increasingly unable to cope with the wide product range, high output and frequently-changing production tasks.
▲Articulated-arm robots with 6 degrees of freedom (DOF)were found to be a better alternative. These robots’ movement capabilities predestine them for tasks like inserting and removing parts into and from injection moulding machines. RKT gradually replaced the linear units with articulated-arm robots. Today these handling tasks are performed by 15 small robots, most of them RV 6S models with up to 6kg payloads and a reach of 696mm. The robots were delivered by the Robtec GmbH of Ergolding, which also handled the system planning and the integration of robots in the manufacturing cells.
▲The robots are installed on the injection moulding machines. When the mould opens the robot’s arm reaches in at high speed, removes the parts using a vacuum gripper and then places them on a conveyor belt or in a collectionbin. Often the robot must remove up to 48 parts simultaneously and place parts precisely in a variety of different cavities.
