Schmalz Solution Increases Pick Rate in Food Processing

The solution consists of two UR cobots and the vacuum gripping solution from Schmalz: A vacuum end effector PXT was configured for each cobot. These end effectors are modular and therefore particularly flexible. If the geometry of the food trays changes at a later date, the components can be recombined. The PXT end effectors have been specially developed for applications that require precise and gentle handling of food packaging. The PSPF bellows suction cups used are made of FDA-compliant silicone and have a particularly soft sealing lip. This prevents the formation of folds in the plastic film and ensures that the trays remain in perfect condition. Another important component of the gripping solution is the Compact Pump GCPi from Schmalz. This vacuum generator supplies the grippers on the robot arm with the required vacuum and, together with the electrical 3/2-way compact valves LQEi, forms a powerful system. The GCPi works with an efficient double-head membrane pump, which is equipped with an integrated energy-saving control. This control regulates the speed of the pump as required, resulting in efficient use of energy and a reduction in operating costs. Thanks to the decentralized installation of the LQEi compact valves on the gripper, Schmalz achieves extremely fast evacuation and placement times. A conveyor belt brings the packaged and labeled plastic trays to the pick-up point of the Schmalz end effectors. Each of the two PXT grippers picks up four food packs and places them in the waiting load boxes – every five seconds, one layer at a time, 96 picks per minute. A roller conveyor then transports these crates to the dispatch area. The entire system works purely electrical. Optimized flow cross-sections and cable lengths enable the gripped workpieces to be put down quickly and reliably without compressed air. This lowers operating costs.
