Device for feeding objects in a chamber filled with gaseous medium

摘要

The invented device is formed by an object feeding module (4) that is mounted in slidable manner in a guide of a lifting device (2) and that is situated opposite a processing chamber (3) orifice. The processing chamber (3) is provided at its inlet with a flange (9). Said object feeding module (4) is separated from the processing chamber (3) by an obturator (7) controlled by a hydraulic cylinder (8). The object feeding module (4) is pushed against the processing chamber (3) by a cover (11) with a pressure piston (12). The module (4) having also a feeding piston (14) is connected by means of a spring (6) with a device (5) serving for defining its position with a compressed air line (13). In the feeding module (4) closed position, pressure in the internal space (Y) thereof is higher than pressure of a working medium contained in inner space (X) of the processing chamber (3). In a modification the object feeding module (4) is formed by a charging casing (1), that opens on both inlet and outlet sides. Alternatively, object feeding module (4) can be formed by a platform (21) that is fixedly coupled with the processing chamber (3) that is slidably controlled by a charging case (22).
