Once full drums are rolled onto the dumping station platform, a hydraulic cylinder raises and seats the drum rim against a discharge hood. A second hydraulic cylinder then tips the drum to an angle of 45o, 60o or 90o with a motion- dampening feature. At full rotation, the slide gate opens to allow controlled discharge of material into downstream process equipment. After the empty container is returned to its upright position, the rolling motion is reversed, and the container is September/October 2018 halted in front of a pneumatically-actuated pusher, which transfers the empty drum to the return conveyor for removal. Meanwhile, another full drum rolls into position on the dumping platform. Photoelectric sensors located along the powered roller conveyor relay the position of empty and full drums to the system controller, which actuates the conveyor to advance full and empty drums on completion of each dumping cycle. The system is also offered in high-lift configurations for dumping into elevated receiving equipment, and in open-chute and dust-free designs for dumping of boxes, bins, pails and other containers. www.flexicon.com turnkey robotic palletising line from Brillopak is claimed to have doubled throughput at the Muntons malted ingredients factory in Stowmarket, UK, and in less than 18 months achieved a return on investment by increasing efficiency and reducing the maltster’s reliance on manual labour. Prior to the automated installation, the Stowmarket mill was operating at maximum capacity, producing 17,000 tonnes of whole, crushed, flaked and milled malted ingredients annually. Used by the food and beverage industries, the business has experienced significant demand for malt ingredients, both domestically and internationally, with high volumes being distributed to Europe, North America, Russia, South East Asia, Japan, Africa and the Caribbean. “Increasing consumer demand for balanced and fortified diets has meant food manufacturers are using malt ingredients as a natural way to add flavour and sweetness to products,” noted Brillopak director David Jahn. Market analysts expect the global malt ingredients market to expand at a CAGR of 7 percent during the period to 2021. As a major supplier in the sector, Muntons wanted to ramp up production and packing capacity. One of the bottlenecks identified by Muntons was its palletising line, which stacks 25 kg sacks of grain from two bagging lines, one manual and one automatic. The challenge was that the existing layer palletiser wasn’t fast or flexible enough to cope with the existing throughput. “We could only ever run one bagging line into it,” explained David Mercer, project engineer at the time of the installation at Muntons. “In the past we’d been able to get around this with careful planning, but it had reached the point where we needed to increase packing volumes.” To facilitate a higher throughput, palletising machine maker Brillopak designed a dual line robotic palletising system incorporating a Nachi LP 130 four axis robot. Brillopak increased the robot’s reach range within the compact factory footprint and low ceiling area by mounting the robot on a plinth. “This enables the robot to work around obstacles like slipsheets and sacks,” commented Jahn. Sacks from two separate packing lines feed the Nachi robot. Each line passes through a bag flattener, metal detector and labeller onto a pick- up conveyor. The robot feeds two different pallet stations, each with its own pallet dispenser. In order to cater to different sack sizes, the robot head automatically adjusts and loads two pallets at a time. Full pallets are moved down the line to a stretch wrapper with hooder. From there they are fed to a series of outfeed conveyors. Palletising at least 600 bags an hour, the Stowmarket site has more than achieved its manufacturing goal of doubling throughput. “We wanted 50 percent more throughput but we got more,” said Mercer. To minimise machine downtime and line stoppages, Brillopak created and tested 65 different pallet load recipes for each robot line, accommodating every conceivable combination of bag size and type. “We wanted a robot that would be easy for us to programme,” explained Mercer. “Our operators appreciate the speed at which product changeovers can now be completed at the touch of a button.” The entire system is driven from a recipe-driven colour touchscreen HMI. Robot signals are fed to the HMI meaning that there is no requirement for the operator to use the robot pendant. For safety, the system is zoned into two areas, with safety guarding and CAT 4 light guards. www.brillopak.co.uk A Brillopack robotic palletising line should yield a return on investment within less than 18 months at Muntons’ Stowmarket malted ingredients factory
