Robots Fit For Food Production A combination of economic drivers determine which technology is best suited Integrating robots further upstream in and future concerns over long term for bacteria control, and to show how the manufacturing process does bring labour resources within the UK’s food European Hygienic Engineering & Design additional complications, including the manufacturing sector has initiated a Group (EHEDG) hygienic guidelines have variability of food products, the fragile significant rise in interest towards robots been used to improve the engineering of and often perishable characteristics of the in recent times. these technologies. product to be handled, high production However, as robots continue to move Historically, robots first found their further upstream in the manufacturing way into the food-manufacturing processes, the requirements for sector through end of line packaging Today’s robot technologies have cleanliness, hygiene and food safety and palletizing applications. The ready successfully addressed the issues of high become more stringent. This means availability of robots with a high payload speed, and deal with product variability that robot manufacturers, system capacity and large work envelopes made and positioning through the use of integrators and end users must give them the ideal fit for these relatively sophisticated sensors and machine vision serious consideration, not only to adhering simple applications. Safety considerations systems. In addition, clever and innovative to current food safety directives, but within these applications were focused gripper concepts have made it possible for ensuring that the type of robot used and entirely on protecting operators through robots to handle a vast array of different its design characteristics are appropriate the use of fencing and / or light-guard food products. for the specific application. systems. Other than maintaining the In this article by Staubli UK’s Laurence Wood, robot technologies are considered from a cleanliness standpoint to 16 FDPP - www.fdpp.co.uk integrity of the cartons and populated pallet, within this environment there are minimal requirements and few considerations in relation to hygiene. speeds and of course a much greater emphasis on cleanliness and hygiene. From a hygiene and cleanliness perspective, using robots does eliminate the many potential opportunities for human borne sources of contamination
