Energy-saving charge transport system in the press-furnace line

An energy-saving charge transport system in a press-furnace line, for articles to be baked from the press to the furnace and for articles baked to a finished product storage area, having two levels of a heat tunnel, wherein

• articles to be baked are arranged on empty transport pallets in two trains of the press, two heat recovery tunnels, the right heat recovery tunnel and the left heat recovery tunnel are situated under the furnace and outside said furnace, the furnace comprises inside two on the contrary movable tracks for articles to be baked,
• each of the heat recovery tunnel having a down level for baked articles and an upper level for raw articles, said baked and raw articles moveably on the contrary directions, said levels arranged respectively with the right train of the press and the left train of the press,
• a first actuator cyclically pushes the pallets with the product to be baked arranged in the first train and delivers the pallets onto the upper level of the first heat recovery tunnel, the transport pallets with the raw charge are delivered, one after the other, to a first elevator, that delivers the pallets with the raw charge onto a level of left-hand furnace track, after which the actuator positions them in a furnace on left-hand track, and after covering the whole length of the left track and after baking them, the pallets with the baked charge are delivered to the second elevator, and the second elevator transports the pallets with the baked charge onto a lower level of a second heat recovery tunnel, the actuator positions the pallet with the baked charge along the second heat recovery tunnel, and further the actuator moves the pallets with the baked charge along the second heat recovery tunnel under the raw charge moved in contrary direction in an upper level of this second heat recovery tunnel, as far as to the pallet unloading station, while in the pallet unloading station, a finished product is taken off the pallets and directed to a finished product storage area after which the empty transport pallets are returned to a press,
• simultaneously the actuator cyclically pushes the pallets with the product to be baked arranged in the second train and delivers the pallets onto an upper level of a second heat recovery tunnel, the transport pallets with the raw charge are delivered, one after another, to the second elevator that delivers the pallets with the raw charge onto a level of right-hand furnace track, after which the actuator positions them on the right-hand track, after covering the whole length of the right track and after baking them, the pallets with the baked charge are delivered to the first elevator that transports the pallets with the baked charge onto the lower level of the first heat recovery tunnel, the actuator positions the pallets with the baked charge along the first heat recovery tunnel and the actuator moves the pallets with the baked charge along the first heat recovery tunnel under the raw charge moved in contrary direction in an upper level of this first heat recovery tunnel, as far as to a pallet unloading station where a finished product is taken off the pallets and directed to a finished product storage area, while empty transport pallets are returned to a press.
