Manufacturing a wide range of spring waters, flavored waters, functional waters, school compliant drinks, premium sparkling pressés, fruit juices, and private label brands, Radnor Hills is an award-winning and growing beverage business. To keep up with demand, it first approached robotics integrator RMGroup in 2018 to investigate automating an end-of-line palletizing operation with a robot arm.
On the line, packs of bottles needed to be palletized 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 formats of one, two, three, or four to keep up with the production line throughput.

Following the success of the initial installation, RMGroup has since supplied another pair of ABB end-of line palletizing systems at the site. A second was installed on Radnor’s tetra pack line, the requirement being to palletize paperboard 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 palletized on euro pallets, at 20 cases per minute.
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.
“The benefits of working with RMGroup and what we feel they particularly do well, is first and foremost they listen to us,” says David Pope, Radnor Hills’ General Manager. “They take on board our requirements - they don't tell us what we should be doing, they listen and come back with us with solutions to make it happen. The whole team has been a pleasure to work with, especially the engineers, who have been extremely knowledgeable and helpful throughout the whole process.”
William Watkins, Radnor Hills' Managing Director added: “I think RMGroup’s experience, their backup and the fact that they have a very conscientious team, means that they really make sure that they don't leave you until you are absolutely 100% happy that the machinery they’ve installed is working absolutely as you expect it to.” -PW
