Abstract
An automatic feeder device for loading full trays over the hopper of machines for packing cigarettes and for discharging empty trays from the hopper, with the aid of a tray-carrying casing which is provided with a gate for closing the tray mouth and with tray-holding arms cooperating with the bottom of the tray. The device includes a path (4) for feeding full trays (2'), this path being directed towards the hopper (1), and a path (6) for discharging empty trays (2'), the discharge path being arranged below the tray-feeding path and being directed away from the hopper. A loading-and-unloading inclined frame (8-8, 9, 10) extends adjacent the paths and has an upper fore end which is disposed adjacent the hopper. The frame is swingably mounted so that it can alternately assume two angular positions: a less inclined position in which its upper fore end is lowered toward the inlet of the hopper, and another more inclined position in which its upper fore end is lifted from the inlet of the hopper. The tray-carrying casing is so mounted as to be both longitudinally slidable and rotatable with respect to the frame, from an overturned upper position over the inlet of the hopper, through an upstanding intermediate position where the empty tray is released to the discharge path, to an upstanding lower position where a full tray is received from the tray-feeding path, and then back to the hopper.
