Device for continuous movement of objects with symmetry, use for visual inspection and control

摘要

A device for controlling a continuous movement of an object with symmetry of revolution ( 1 ) comprises a conveyor ( 5 ) having two parallel guides, ( 6 ) and at least one pair of belts ( 8 ) stretched on the guides, between and on which these objects move at the level of the guides. These belts form an angle ( 11 ) between a top track and a lower track of each of the belts. The belts in the pair have the same direction of rotation around the guides, the same value of the measured angle ( 11 ) from the upper track to the lower track, and the same displacement speed. Preferably, the pair of belts consists of a single folded belt.
