Patent number: 9174364Abstract: The pellet dosing apparatus comprises a hopper (10) pouring pellets (1) on a chute (30) which is vibrated by a vibrator device (3) to move the pellets (1) forward along the chute until dropping them from a discharging end (30a). A counting device (20) is arranged for counting the number of pellets (1) falling from said discharging end (30a) of the chute (30) into a dosing container (4). The pellets (1) are retained in the dosing container (4) by transferring means until their number reaches an amount corresponding to a pre-established dose determined by control means based on a counting signal received from said counting device (20). The control means then control the transferring means to transfer the pellets from the dosing container to an output duct.Type: GrantFiled: May 9, 2014Date of Patent: November 3, 2015Assignee: ULTRASION, SLInventors: Francesco Puliga, Matias Sacristán Erriquez, Antoli Plantà Torralba, Francisco Javier Plantà Torralba

Patent number: 8758000Abstract: The apparatus comprises a melting chamber (6) in communication with a molding cavity made up by two half-molds (1, 2) in a close position, an inlet duct (3) through which plastic material is fed into said melting chamber (6), an ultrasound vibration element (4) activated by an ultrasound generator (5) and provided with an end portion inserted in the melting chamber (6) through an access opening thereof, and motion means for generating a relative displacement between the ultrasound vibration element (4) and the melting chamber (6). The ultrasound vibration element (4) is supported by adjustment means so as to adjust the position of a longitudinal axis (E) thereof in two cross directions (X, Y) perpendicular to each other and perpendicular to an axial direction (Z) parallel to a longitudinal axis of the melting chamber (6).Type: GrantFiled: November 13, 2012Date of Patent: June 24, 2014Assignee: Fundacio Privada AscammInventors: Francesco Puliga, Matías Sacristán Erriquez, Francisco Javier Plantà Torrallba, Alfons Navarro Solanilla

Patent number: 8182255Abstract: Device and apparatus for selective deposition of molten plastic material and method of manufacture by selective deposition. The device and the apparatus include a melting chamber communicated with a portion of a sonotrode of an ultrasonic transducer, a passage for feeding plastic material, and at least one outlet opening for supplying molten plastic material dropwise or continuously. A feeding of plastic material to the melting chamber is provided. The method includes feeding plastic material to the melting chamber configured in a device for selective deposition installed in a head of a piece of industrial manufacturing equipment, which is moved according to a strategy of its path defined by numerical control on a deposition area, and pouring plastic material melted by ultrasound through the outlet opening.Type: GrantFiled: August 25, 2008Date of Patent: May 22, 2012Assignee: Fundacio Privada AscammInventors: Francisco Xavier Plantà Torralba, Francesco Puliga, Alvaro Pallares Bejarano
