Abstract: A mail sorting device wherein an inclined supporting surface cooperates with a guide device presenting a number of push surfaces spaced along the supporting surface and movable from a back stop towards a front stop adjacent to the upper end edge of the supporting surface. The supporting surface supports a number of flat rectangular mail items grouped into stacks interposed between adjacent push surfaces; and the sorting device presents a grip-and-carry device facing the end edge of the supporting surface, and in turn presenting a gripping head movable to and from the supporting surface to withdraw one mail item at a time from the stack and feed it to a conveyor device. The guide device provides for feeding the push surfaces back from the front stop to the back stop.

Abstract: An accumulating device having ten accumulating units connected at the input to a conveyor belt system and designed to house a number of mail items. Each accumulating unit comprises a conveyor system composed of two belts contacting each other along a substantially straight portion and having a sensor for generating an enabling signal upon a mail item being fed into the accumulating unit. As a consequence of the enabling signal, the belts are shifted one discrete step so that the mail items fed into the accumulating unit are inserted between the two belts and overlap one another.

Abstract: A device whereby a pile of rectangular items is placed on an inclined surface and pushed towards the straight front edge thereof by a push unit. The surface presents two pairs of conveyor belts parallel to each other and coplanar with the surface; and the pile is arrested upon a bottom portion of the first item in the pile activating a first or second limit stop sensor, which activates a respective pair of belts so as to move the bottom left or right portion of the item and so orient the item in relation to a gripping plane. A gripping unit with two suction cups movable along a three-dimensional trajectory grips the oriented item and feeds it to a follow-up conveyor belt.

Abstract: A robot for emptying a postal machine having a plurality of containers into which the postal items (letters and cards) are delivered and form a substantially ordered stack of items, one on top of another. The robot includes a base structure located on a rectilinear structure arranged parallel to a wall of the postal machine and a columnar structure which is fixed to the base structure and supports a slide slidable vertically on the columnar structure itself. The slide supports a pair of arms which are slidable relative to the slide and have gripper devices at their ends arranged to be introduced into one of the containers to grasp a stack of postal items, to withdraw them from the container and to deposit them on a conveyor belt.
