Claim 7:
8. A method for emptying a container (100), containing a fluid product, by means of a system (1) according to claim 1, the method comprising the following steps:
arranging the container (100) in a predetermined position below the pumping unit (2) comprising at least the pump (5) and the scraping plate (4);
moving the pumping unit (2) close to a mouth of the container (100);
detecting the passage of the pumping unit (2) at the first level of the container (100);
upon detection of the passage of the pumping unit (2) at the first level, activating the pump (5);
making the pumping unit (2) descend towards a bottom of the container (100) so that the pump (5) sucks the product inside the container (100) during the descent of said pumping unit (2);
detecting the passage of the pumping unit (2) at the second level of the container (100), said second level being lower than said first level;
upon detection of the passage of the pumping unit (2) at the second level, stopping the descent of the pumping unit (2);
deactivating the pump (5);
dispensing air coming from the air supply circuit to the pumping unit (2) inside the container (100);
making the pumping unit (2) return upwards towards the mouth of the container (100) through the combined action of the pneumatic cylinder (6) which is operatively active on the pumping unit (2) and of dispensed air;
detecting the further passage of the pumping unit (2) at said first level;
upon detection of the further passage of the pumping unit (2) at said first level, interrupting the dispensing of air;
extracting the pumping unit (2) from the container (100) through the action of the pneumatic cylinder (6).
