ABSTRACT:
An automated liquid container filling apparatus is disclosed which automatically fills cups with a fluid and then seals the cups with covers. The apparatus includes a circular table which is rotatably mounted on a base member for rotation about an axis perpendicular to the base member, having a plurality of holes therethrough spaced at equal angles about the circumference of the table. A motor is mounted to the base member and is operatively connected to the table for periodically rotating the table through the angle. A cup dispenser is mounted on the base member at a first position over the table, having a plurality of cups stored in a storage portion and a cup delivery mechanism adjacent to the cup storage portion which is operatively connected to the motor, for periodically dispensing one of the plurality of cups into each of the holes in the table, in synchronism with the periodic table rotation. A filling station is mounted on the base member at a second position over the table, having a fluid reservoir storing a fluid to be dispensed into the cups and a fluid delivery mechanism connected to the reservoir, which is operatively connected to the motor for periodically dispensing a predetermined volume of the fluid through a delivery nozzle connected therewith, into each of the cups in the holes in the table, in synchronism with the periodic table rotation. A cover dispenser is mounted on the base member at a third position over the table, having a plurality of cup covers stored in a cover storage portion and a vacuum picking nozzle adjacent to the cover storage portion which is operatively connected to the motor for periodically picking one of the plurality of covers and placing it over the mouth of each one of the cups filled with fluid in the holes in the table in synchronism with the periodic table rotation. A heat sealing station is mounted on the base member at a fourth position of the table, having a heating element which is operatively connected to a motor for periodically heating the cover placed over the mouth of each one of the cups filled with the fluid in the holes in the table, to heat seal the cover to the cup in synchronism with the periodic table rotation. A cup removal station is mounted on the base member at a fifth position adjacent to the table, having an elevator which is operatively connected to the motor, for periodically raising the heat sealed cup from the level of the table to the level of a removal ramp. The removal station also has a rake which is operatively connected to the motor, for periodically pushing the raised, heat sealed cup onto the removal ramp in synchronism with the periodic table rotation. The resulting automated liquid container filling apparatus automatically fills cups with fluid and seals the covers in a more sanitary and efficient manner than has been available in the prior art.
