Two of the highest speed stretch wrapping systems in Australia have recently been installed in a Friskie pet food factory in country New South Wales.
The Robopac Genisis stretch wrappers were supplied by R.A.Technologies, part of the group that also includes Robotic Automation , one of the leading robotic palletiser suppliers.
According to director Colin Wells the systems at the Friskies plant can stretch wrap at a rate of 110 pallet loads an hour each. And that includes an auto top sheet.
The rotary systems, which circle the stationery pallet load, use cast film and have a built-in pre-stretch feature which stretches the film up to 300 per cent, as required.
Wells said the system got its speed from its rotary action and a unique, patented on board generator, similar in principle to a bicycle dynamo, which eliminated the need for a costly and high maintenance slip-ring type of power delivery system.
The stretch wrappers also came with automatic roll change, which meant enough film could be stacked up for a whole shift and the machine would change spools automatically without requiring any labour.
Wells said that as well as installing the Robopac wrappers, R.A.Technologies had upgraded the associated pallet conveying systems.
