<p>Buffer storage unit for accumulating and releasing, in rows which are equidistant or have a programmed timing, products which arrive from a continuous advancement line and are arranged in non-equidistant rows, including a first conveyor belt (2) and a second conveyor belt (3) which are respectively actuated continuously and stepwise, and which have respective active portions (2a,3a) extending horizontally after one another. The belts are closed on themselves in a loop and are wound around respective sets of rollers, and the output roller (5a) of the first belt (2) and the input roller (7a) of the second belt (3) are mounted on a first slider (8) which is horizontally slidingly guided and which is associated with actuation elements which are controlled by sensors (16,17) which detect the presence of the products. The first one (16) of the sensors is arranged at the output of the active portion (2a) of the first belt (2), and the second one (17) is arranged at the output of the active portion (3a) of the second belt (3), so that upon the arrival of a product at the first sensor (17) the slider (8) is actuated in the direction opposite to the product advancement direction and so that upon the release of a product from the second belt (3) the slider (8) is actuated in the product advancement direction. <IMAGE></p> |
