Title: AN AUTOMATIC LIQUID FILLING DEVICE
Abstract:
The present invention relates to an automatic liquid filling device essentially consisting of a support structure (5) which is rotatably engaged with a parallelogram with bearings (4) which is connected to an upright (20), secured to one end of which there is a plate (2), which is envisaged to support a container (3) to fill. Furthermore, engaged with the parallelogram with bearings (4) on the opposite side to the upright (20) is a plate (40), on which a pair of contact elements (60 and 70) rest, the said elements being engaged with the respective shafts, each one of which being located inside a corresponding proportional valve (6 and 7) engaged with the support structure (5). The device comprises a pair of valves (6 and 7) which are structurally identical but operate in an inverse manner, wherein the proportional valve (7) manages an air inlet while the valve (6) manages an outlet. In particular, the valve (7) features a first pipeline (72) connected to a "tap" ( 140) envisaged to manually adjust the opening speed of a shutter ( 1 1 ) and a second pipeline (73) which is connected to a pressure regulator ( 1 7) whose task is to manage the response of the weighing unit (8 1 ) featured on the parallelogram with bearings (4). Furthermore, the valve (6) features a first pipeline (62) connected to a contractile linear actuator (9) and a second pipeline (63 ) which is connected to the pressure regulator ( 17). In particular, the device comprises : a horizontal support (50) engaged with the support structure (5 ) and from which a vertical support (51) branches off, the latter supporting a contractile linear actuator (9) envisaged to manage the dispensing of the liquid into the container; a three-way pneumatic valve (12) located at the free end of the horizontal support (50), equipped with a control wheel (120), to actuate a valve (13) envisaged to manage the passage of a flow of air into the proportional valve (7) through a pipeline (130); and a pipe (14) located below the horizontal support (50) and connected, at one end, to a tank containing the product to dispense and, at the other end, to a dispenser (15), which is equipped, internally, with a cylindrical choke (16) for the gradual inlet of the liquid into the container (3).
