1. An aseptic filling machine for envelope-type bags having a filling mouth closed by a removable cap located on a side of the envelope, the filling machine comprising:
an empty bag supply device and a removal device to remove the bags when filled; a carousel device equipped with a rotating platform having continuous motion on which at least two filling stations are located, said at least two filling stations being circumferentially equidistant, each filling station comprising a rest plane for the bag and a filling group; a feeder and positioning device of the empty bag in a first filling station; and a discharging device of the filled bags from the filling station adjacent the first station, each filling group comprising:
a sterile chamber;a raising device configured to raise the mouth of an empty bag lying on the rest plane internally of the sterile chamber;an overpressure device configured to place the sterile chamber in slight overpressure;a removal device configured to remove the cap from the filling mouth and position the cap by a side of the filling mouth, and vice versa, said removal device being placed internally of said sterile chamber; anda dispenser-batcher device that is vertically slidable into the sterile chamber and configured to engage with the filling mouth,wherein the removal device comprises a radial vertical plate that is solidly constrained to the carousel, on which a plate slides vertically, the plate comprising a horizontal shelf that rotatably supports a tubular body in which a coaxial shaft is inserted, a displacement mechanism being provided configured to vertically move the plate, the tubular body being inserted in the underlying sterile chamber, jaws of a first pair of pliers being hinged between the ends of the tubular body and the shaft, and a device being provided configured to rotate, in a coordinated and independent way, the tubular body and the shaft about the axis such as to open and close the first pair of pliers and rotate the tubular body and the shaft by at least 90°.
