The pre-packed sandwich market is enormous, but the production of sandwiches is very labour intensive. This project included industrial partners, Gunstones Bakery, who manufacture sandwiches for Marks and Spencer, INBIS plc and the University.
The project involved the design, construction and testing of an automated system for the assembly and packaging of triangular sandwiches. The work analysed the current manual production techniques and developed a number of modular workstations, which could be incorporated into an existing line in place of human operators. The developed machine completes the final assembly of the sandwich and then cuts and packages it into a plastic skillet (container) for dispatch.
To test the overall performance of the system, real plant trials were conducted with the machine in a sandwich production factory.
