file into both robotic cells, ready for automated case loading. “Brillopak’s robot is impressive to watch. It never misses a beat and is capable of orientating packs quicker than any person is able to do,” comments Andy This level of presentation precision was one of the key drivers behind automating the case loading operation at Rushden. Previously, potato packs were loaded manually into crates. It was labour intensive, incurred packing bottlenecks and resulted in messy tray presentation. STAFF SATISFACTION Having worked on both the manual packing and now automated lines, machine operative Dave reflects on the differences the robot cells have made to workers and waste. Noting that the UniPaker cell is much more product and user friendly, Dave comments: “By removing 90% of the physical labour from the packing production area, health & safety and people’s approach to teamwork has improved. It’s a much calmer environment and so much better for staff welfare. It’s almost hypnotic to watch when the robots are running.” Additionally, with the introduction of the robotic lines and glove end effector, Dave reports less product rework as a result of split bags. A simple, intuitive HMI means that it’s easy for operatives to select the correct programme and case loading patterns for product changeovers David adds: “Suctioning polybags of heavier potatoes with varied shapes is equally challenging. Because it’s not a smooth surface, bags frequently sag and drop onto the packing conveyor, causing the packing line to stop. These frequent line stops have a significant impact on line efficiency and ultimately bottom line profit.” Rather than using stainless steel, which would add to the weight being repeatedly lifted, Brillopak designed the end-effector using soft food-grade material. DELTA DEXTERITY For this Morrisons potato packing line, Brillopak installed two specialist four- arm Spider (Delta) robots within each robotic cell. Each robot has a payload of 5kg, including a head with rotation functionality. In most fresh produce applications a three-arm robot will offer sufficient payload highlights David. With a reach of 1130mm - 30% more than similar sized robots - the UniPaker system delivers dexterity in a compact footprint. Rumble conveyors settle the packs and deliver them in single Describing the robot lines as easy to operate, Dave says the system set up and HMI is intuitive to use, particularly for product changeovers. Having been involved in writing guidelines for team members to reference he affirms: “It’s so straightforward to use that I’m never worried about pressing the wrong button and breaking the system!” Forming part of a site-wide investment in front and back end manufacturing improvements, the Rushden site has seen improvements in Overall Equipment Effectiveness (OEE). Andy attributes these improvements to the increased packing speed, better presentation, less front to back end bottlenecks and fewer staff frustrations. www.brillopak.co.uk 33
