摘要:
A machine (1) for forming glass articles has at least one gob delivery unit (6) for conveying the gobs of glass to a forming mould (3) selectable from a plurality of forming moulds; the unit (6) having an upper inclined channel (7) with a rectilinear axis (8), a lower deflector (13) having an outlet portion (15) facing the mould (3), and an adjustment device (18) for varying the position of the outlet portion (15) upon variation in the mould (3) utilised; the adjustment device (18) having an attachment element (31a) coupled to the outlet portion (15), and a pair of actuators (24) (32) for moving the attachment element (31a) in two rectilinear directions (22) (30), of which one (30) lies in a vertical plane (P2) substantially parallel to the axis (8) of the channel (7).
摘要:
A punch assembly (1) for a machine for shaping glass articles, in which at least one casing (7), adapted to support a punch (11) for movement relative to the casing (7), is connected to its own fixed support (2) by a rapid-connection device (12) which has two jaws (13) carried by one component selected from the fixed support (2) and the casing (7), and a pair of counter elements (24) each associated with a respective jaw (13) and carried by the other of the fixed support (2) and the casing (7); the counter elements (24) being movable under the action of a drive unit (28) between an operative position in which they cooperate with the jaws (13) to attach the casing (7) to the fixed support (2) and a rest position in which the counter elements (24) are disengaged from the jaws (13) allowing the casing (7) to be moved away from the fixed support (2).
摘要:
An actuating assembly (1) for moving glass articles (2) and including a gripping member (5) for positively engaging an article (2) for transfer; a pneumatic actuator (6) for moving the gripping member, in use, to and from the article (2); an angular actuator (4) for rotating the pneumatic actuator (6) about a rotation axis (7); and a pneumatic circuit (61) for connecting the pneumatic actuator (6) to a compressed air source; the pneumatic circuit (61) having a first (83a) and a second (83b) pair of compressed air passages (83), a first selection assembly (65,73,74,79,80) for selectively connecting the pairs (83a)(83b) of passages to the compressed air source, and a second selection assembly (86) for selectively connecting the pairs (83a)(83b) of passages to the pneumatic actuator (6).
摘要:
A method for supplying air under pressure to a plurality of pneumatic operating units (1a, 1b) of a forming machine for forming glass articles; the method comprising the steps of determining, for each of the operating units (1a, 1b) and for at least one operating condition of the operating unit (1a, 1b) itself, an optimum value of a parameter of the air flow to be supplied, of memorizing this optimum value and activating a valve assembly (13, 14) associated with the unit itself to deliver the respective air flow by means of a control signal depending solely and only on the memorised optimum value.

摘要:
A glass gob distributor (1) wherein at least one gob distributing body (8) is connected to a fixed frame (2) so as to rotate about a respective hinge axis (11), and is moved in relation to the frame (2) by an actuating assembly (14) for positioning the distributing body (8) in a number of angular gob feed positions; the actuating assembly (14) having a linear electric motor (44) controlled by an electronic control unit (48), and the translating member (45) of which is connected positively to the distributing body (8) by a linear-rotary motion converting device (16).
