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 A simple, intuitive HMI means it’s easy for operatives to select the correct programme and case loading patterns for product changeovers “Previously, pierced bags has been one lifted, Brillopak designed the end-effector of the downsides to using grippers using soft food-grade material. on automated case loading systems,” says Brillopak director David Jahn. DELTA DEXTERITY “Additionally, when layer picking grippers For this Morrisons potato packing line, or bomb bay doors release potatoes Brillopak installed two specialist four- into trays, they are typically dropped in a arm Spider (Delta) robots within each haphazard way above each tray in order robotic cell. Each robot has a payload for the tooling to have space to open. Not of 5kg, including a head with rotation only does this damage the product, the functionality. In most fresh produce presentation is quite hit and miss.” applications a three-arm robot will offer sufficient payload highlights David. David adds: “Suctioning polybags of 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. 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!” heavier potatoes with varied shapes is With a reach of 1130mm - 30% more equally challenging. Because it’s not a than similar sized robots - the UniPaker smooth surface, bags frequently sag and system delivers dexterity in a compact drop onto the packing conveyor, causing footprint. Rumble conveyors settle the the packing line to stop. These frequent packs and deliver them in single file into Equipment Effectiveness (OEE).
