Date Jun. 25, 1992.A supply container holds a large amount of citrus fruits from which juice is to be pressed out which fruits are to leave one after the other the supply container through an opening. In order to transport the citrus fruits a partial area of the floor surface located in the center of the container of the otherwise inclined rising floor surface is formed by a plurality of parallel rollers located side by side. All have a non-circular cross-section with a circumferential shape composed of three convexly domed circumferential sections and are driven in the same sense of rotation and the same angular position, such that citrus fruits which rest on the rollers are transported in a direction towards the exit opening. Because the citrus fruits located in a plurality of layers in the supply container are apt to form a bridge due to the consistence of their surfaces the entire amount of citrus fruits positioned in the container is additionally kept moving by pistons which move up and down between the fruits, which pistons project upwards through the inclined rising floor surface adjacent the row of rollers. At both sides of the row of rollers three pistons are respectively mounted to a rail extending under the bottom floor. The two rails are interconnected at one of their ends by a pivot axis. Rotating cams which are positioned under the rails and on an axis of one of the driven rollers cause the up and down movement of the rails and the pistons. |
