Abstract: A device for stacking articles includes a feeding conveyor including a plurality of contact elements, each for making contact with a single article to convey it along a conveying path. A first transport surface supports the articles along a first portion of the conveying path. A predetermined number of conveying planes support the articles along a second portion of the conveying path which follows the first portion of the conveying path, including a first conveying plane positioned at a first height; a second conveying plane positioned at a second height different from and higher than the first height; and a movable surface for directing articles, movable between a number of positions equal to the predetermined number of conveying planes, to selectively and alternatively connect the first transport surface with one of the conveying planes.

Abstract: A device for the accumulation and release of products arranged within containers comprises a main accumulation unit with a reception opening and a first delivery opening, the containers being guided between the openings. The device is provided with a second accumulation unit operationally in communication with the main unit and having a second delivery opening. The device uses an actuator for selectively moving containers loaded with products from the main accumulation unit to the second unit, in order to selectively by-pass the first delivery opening and enable containers to be unloaded at the second delivery opening provided in the second accumulation unit.
