A system in which a succession of products (12) to (16) traverse a gap between two conveyors (10, 18), comprises a ring (32) carrying an array of one or more equi-spaced laser displacement transducers (36-42) connected to a computer (48). The ring is disposed perpendicular to the direction of product movement, such that each product (e.g. a log of food) passes through its central region, the ring being rotatable in a continuous or oscillatory manner. Signals received by the computer from the transducers are stored and computed to determine the shape and/or size of the product to enable the product to be cut into an optimum number of pieces. A method is described for determining volume and thereby weight using mean density values for the products, of irregularly shaped bulk product, particularly fresh meat. |
