Abstract
A method for detecting the defective status of an article intended to be contact-filled with a pourable product stored in a tank using a filling device includes creating a tight-fluid contact between an opening of an article and a first fluidic line defined by the filling device; setting a second valve in a second closed position; setting a first valve in a first open position; measuring the flow of the pourable product along the first fluidic line; and detecting that the article is defective if the flow is greater than a threshold value.
Claims15
A method for detecting the defective status of an article intended to be contact-filled with a pourable product stored in a tank using a filling device, comprising:
- creating a tight-fluid contact between an opening of the article and a first fluidic line;
- setting at least one second valve in a second closed position;
- setting a first valve in a first open position;
- measuring a flow of the pourable product along the first fluidic line;
- detecting that the flow is greater than a threshold value;
- and
- detecting that the article is defective when the flow is greater than the threshold value,
- wherein the filling device comprises:
- the first fluidic line fluidly connectable in a selective way with the tank, connected with a filling mouth of the filling device, and adapted to convey the flow of the pourable product from the tank towards the filling mouth;
- the first valve interposed along the first fluidic line and adapted to be selectively arranged either in the first open position in which the first valve allows the flow of the pourable product along the first fluidic line and towards the filling mouth or in a first closed position in which the first valve prevents the pourable product from flowing along the first fluidic line;
- a second fluidic line fluidly connected with the filling mouth and adapted to allow an escape of an aeriform contained in the article during filling of the article;
- and
- the at least one second valve interposed along the second fluidic line and adapted to be selectively arranged either in a second open position in which the at least one second valve allows the escape of the aeriform along the second fluidic line and away from the filling mouth or in the second closed position in which the at least one second valve prevents the aeriform from escaping flowing along the second fluidic line.
A filling device for contact-filling an article with a pourable product, comprising:
- a filling mouth adapted to be in tight-fluid contact with an opening of the article during filling of the article;
- a first fluidic line fluidly connectable in a selective way with a tank, connected to the filling mouth, and adapted to convey a flow of the pourable product from the tank towards the filling mouth;
- a first valve interposed along the first fluidic line and adapted to be selectively arranged either in a first open position in which the first valve allows the flow of the pourable product along the first fluidic line and towards the filling mouth or in a first closed position in which the first valve prevents the pourable product from flowing along the first fluidic line;
- a second fluidic line fluidly connected with the filling mouth and adapted to allow an escape of an aeriform contained in the article during the filling of the article;
- at least one second valve interposed along the second fluidic line and adapted to be selectively arranged either in a second open position in which the at least one second valve allows the escape of the aeriform along the second fluidic line and away from the filling mouth or in a second closed position in which the at least one second valve prevents the aeriform from escaping along the second fluidic line;
- a measuring device adapted to measure a quantity associated with the flow of the pourable product along the first fluidic line;
- and
- a control unit programmed for:
- setting the at least one second valve in the second closed position;
- setting the first valve in the first open position;
- and
- detecting that the article is defective if the flow is greater than a threshold value.
