ROBOTS AS MASTER BUTCHERS An innovative solution for processing pork and removing bones from pork legs can be seen in this Japanese system, which incorporates three Stäubli sixaxis RX160 HE robots operating as master butchers. The specifications for robotics in a meat factory could not be more onerous. Chief among them are the strict hygiene requirements that apply to the handling of fresh meat. In addition, expectations in terms of speed, precision and flexibility are set high, as no fewer than 500 pork legs enter and leave the line each hour. The functionality of the robots operating within this system are at the highest levels possible, given the special conditions prevailing in the meat processing industry. Also, because no one piece of pork is the same as another, flexibility is required to allow high-speed processing Simon Jenkins expands on the capabilities of this system: “This system clearly demonstrates what the latest generation technologies are capable of and therefore what can be achieved here in the UK. In this application, an X-ray system is used to detect the position of the bones within the meat, and the exact incision line for the robots is then calculated. A perfect solution, but one that is also subject to the vagaries of the meat processing industry. The fact that the meat hanging on its hook is liable to shift its position on the overhead conveyor within certain limits means that the robots must operate in a highly coordinated way to achieve the correct cut and avoid the bones.” The de-boning system represents a high level application of robots within the food sector, however there are also many other less complex applications, such as handling and packing products, where robots can be used to address the numerous issues facing the UK’s food manufacturers. Of course, this will require investment by manufacturers, and historically the traditional short term view on payback on capital projects is often cited as a reason to avoid investing in new equipment or technology such as robotics or automation. Taking an alternative view, either on the duration of the payback period and / or considering flexible financing options such as hire or leasing, may open the door to the introduction of the technology which could potentially transform productivity levels. Improvements as a result of this investment may actually contribute to the security of contracts with customers and ultimately the long term future of the business. The flexibility of robots, for example, allows them to be used for new products or new contracts and their inherent reliability means that they will provide years of service. Having this type of technology in place when bidding for new contracts can also differentiate suppliers and provide a competitive advantage. www.staubli.com FDPP - www.fdpp.co.uk 51
