<p>The surveillance system comprises: moving means (12, 13) for causing indeterminate quantities of product to run in a form of a substantially flat and continuous layer within an inspection space (20); means (25, 26) for illuminating the product running in the inspection space (20), at least a television camera (21) destined to acquire a continuous succession of images of the product running in the inspection space (20), a transfer device (30) of the product located downstream of the inspection space (20), destined to receive the inspected product, an expulsion group (41, 42) of the product, acting on a normal flow of the product along the downstream transfer device (30) in order on command to deviate a limited quantity of the product towards a discharge, an electronic processing device (51) destined to control images acquired by the television camera (21) and to command activation of the expulsion group (41, 42) of the product, when the processing device (51) detects at least a single defective product, the activation being commanded such as to expel a limited mass of product containing the single defective product. The moving means are able to cause the products, one by one, to roll, with a rotation about an axis thereof, in the inspection space (20). A system is realised which is able to optimally eliminate the defective products, operating automatically on the production line and preferably located just upstream of the packing stage.</p> |
