Manufacturing a wide range of spring waters, flavoured waters, functional waters, school compliant drinks, premium sparkling pressés, fruit juices and own label brands, Radnor Hills first approached RMGroup in 2018 to investigate automating an end-of-line palletising operation with a robot arm.

On the line, packs of bottles needed to be palletised at a rate of 14 packs per minute. Given the throughput and pallet stack formats, RMGroup needed to ensure that the robotic solution could multi pick packs up to four at any one time, and then place them onto a pallet in one’s, two’s, three’s or four’s, to keep up with the production line throughput. By using ABB robot studio, RMGroup’s mechanical design and technical department recommended the use of a bespoke gripper, thereby enabling the robot to stack the packs onto pallets at the desired rate. Robot studio also helped RMGroup to decide which ABB robot would be best suited for the project, thereby optimising the ROI.

Following the success of the initial installation, RMGroup has since supplied another two ABB end-of line palletising systems at the site. A second was installed on Radnor’s tetra pack line, the requirement being to palletise cardboard cartons from dual production lines at a rate of 6 cases per minute; a third line was installed on Radnor’s canning line, involving a much higher output of 24 packs, 12 of which needed to be palletised on euro pallets, at 20 cases per minute.
