<p>The apparatus of the invention consists of an ordinary laser scanner (such as for example those used for the reading of optical codes) in which the data obtained from the scanning are processed, for detecting the presence and the position, on a supply plane, of objects having heights even very different among themselves. The detection of the presence of an object, and its position, is carried out taking advantage of the luminous contrast between the surface of the same object and the bearing surface of the supply plane. The detection of the presence and the position of the object can be combined with the reading of an optical code positioned on the object. Furthermore, the use of a modulated light laser scanner, allows the implementation of the above mentioned operations with the measurement of the distance of the object from the same scanner, in this way calculating the overall encumbrance of the same object. This allows the optimization of distribution process and management of warehouses in the handling plants for the distribution and sorting of objects. <IMAGE></p> |
