A tile stacking apparatus, comprising: a stacking zone of tiles, in which the tiles are progressively stacked on one another; conveyor means, for conveying tiles to be stacked towards the stacking zone; the conveyor means comprising two conveyor elements, which: are arranged above the stacking zone such as to convey a tile to be stacked into a transfer position which is proximal to the storage zone; are distanced from one another such as to respectively contact a first lateral edge and a second lateral edge of the tile to be stacked, thus supporting the tile to be stacked; are configured such that a pressure exerted on the upper wall of the tile to be stacked which has arrived in the transfer position can lead to a disengaging of the conveyor elements from the tile to be stacked; the apparatus further comprising a mobile release element for acting on the upper wall of the tile to be stacked, once the tile to be stacked has arrived in the transfer position, such as to cause disengagement of the tile to be stacked from the conveyor elements; characterised in that it comprises: aspirating gripping means of the tile to be stacked, activatable such as to retain the tile to be stacked; the aspirating gripping means being mobile between the transfer position and the stacking zone, such as to enable gripping the tile to be stacked when the tile is arranged in the transfer position, the transfer of the tile to be stacked towards the stacking zone and the release of the tile to be stacked in the stacking zone; and in that the mobile release element comprises a stem and a roller, borne idle by the stem, the roller being arranged in such a way as to press on the upper wall of the tile to be stacked, once the tile has reached the transfer position, such as to determine the disengagement of the tile to be stacked from the conveyor elements. a stacking zone of tiles, in which the tiles are progressively stacked on one another; conveyor means, for conveying tiles to be stacked towards the stacking zone; the conveyor means comprising two conveyor elements, which: are arranged above the stacking zone such as to convey a tile to be stacked into a transfer position which is proximal to the storage zone; are distanced from one another such as to respectively contact a first lateral edge and a second lateral edge of the tile to be stacked, thus supporting the tile to be stacked; are configured such that a pressure exerted on the upper wall of the tile to be stacked which has arrived in the transfer position can lead to a disengaging of the conveyor elements from the tile to be stacked; the apparatus further comprising a mobile release element for acting on the upper wall of the tile to be stacked, once the tile to be stacked has arrived in the transfer position, such as to cause disengagement of the tile to be stacked from the conveyor elements; characterised in that it comprises: aspirating gripping means of the tile to be stacked, activatable such as to retain the tile to be stacked; the aspirating gripping means being mobile between the transfer position and the stacking zone, such as to enable gripping the tile to be stacked when the tile is arranged in the transfer position, the transfer of the tile to be stacked towards the stacking zone and the release of the tile to be stacked in the stacking zone; and in that the mobile release element comprises a stem and a roller, borne idle by the stem, the roller being arranged in such a way as to press on the upper wall of the tile to be stacked, once the tile has reached the transfer position, such as to determine the disengagement of the tile to be stacked from the conveyor elements. aspirating gripping means of the tile to be stacked, activatable such as to retain the tile to be stacked; the aspirating gripping means being mobile between the transfer position and the stacking zone, such as to enable gripping the tile to be stacked when the tile is arranged in the transfer position, the transfer of the tile to be stacked towards the stacking zone and the release of the tile to be stacked in the stacking zone; and in that the mobile release element comprises a stem and a roller, borne idle by the stem, the roller being arranged in such a way as to press on the upper wall of the tile to be stacked, once the tile has reached the transfer position, such as to determine the disengagement of the tile to be stacked from the conveyor elements.
