Frozen beef patties go robotic

Since Ivor Karan established his feedlot in 1974, Karan Beef has seen steady growth. Now the firm’s top-quality beef products are benefitting from robotic cartoning.

Robotic end effectors are guided to the precise position of the incoming flow-wrapped patties by a vision system.

Located just south of Johannesburg, Karan Beef is a leading supplier of high-quality beef products in South Africa. In recent years, the firm has seen so much growth in sales of its frozen hamburger patties, an upgrade in packaging operations was essential.

Karan turned to USS Pactech for the packaging equipment it needed. That firm represents both Cama Group and PFM, two well known Italian packaging machinery OEMs that Karan identified as the answer to its requirements. From PFM came three Zephyr flow wrappers. And from Cama came the following: a Model FA 024 carton forming machine, four in-line Triaflex Delta Robots, and one Model CD 058 carton closing machine.

“We had a limited space available in the plant out of which we needed greater production,” says Gavin Paton, Technical & Production Manager at Karan Beef. “Before this equipment arrived, we were putting the factory through 20-hour days to keep up with demand. Now we get more production out of a single-shift day. And we have capacity available that will let us continue to grow. On top of all that, we have been able to put 45 people into more meaningful positions elsewhere in the company.”

The individual patties, each one weighing 50 g, are frozen in two spiral freezers just ahead of the three flow wrappers. Karan always wraps the patties in pairs in a single layer, one ahead of the other. Clear biaxially oriented polypropylene is the film applied by the PFM wrappers.
