摘要:
A push device (1), for transferring glass articles (2) from an intermediate supporting plate (3) to an unloading conveyor, has at least one seat (13) for housing an article and which is bounded by at least two flat supporting surfaces (10a)(11a) converging with each other and forming between them an angle (A) of over 90°; the article being retained close to a convergence area (14) of the flat supporting surfaces by a circuit for feeding compressed air between the flat supporting surfaces.
摘要:
In a proportional valve assembly (1), particularly for supplying compressed air on a glassware molding machine (3), a tubular body (18), having an axis (6) and air inlet (19) and outlet (20) ports, houses a slide member (22) which is slid axially along the axis (6), to open and close the inlet and outlet ports, by a linear actuator (9), on the one hand, and, on the other, by the reaction exerted by an elastic body (26) and the compressed air; the elastic body (26) being spaced apart from the slide member (22) and connected to the slide member by a relatively moving device (37).
摘要:
The control system is defined by at least one subsystem for controlling electric motors, and by a subsystem for controlling pneumatic article molding movements, each subsystems including a central unit (50, 51), a plurality of peripheral units (60, 61), and a second-level serial bus (56, 57) interposed between the respective central unit (50, 51) and respective peripheral units (60, 61). A first-level serial bus (54) is connected between the two central units (50, 51); the peripheral units (60, 61) are intelligent types; and the first-level bus (54) and second-level buses (56, 57) are "fieldbuses" in CANbus technology and employ a CANopen protocol.
摘要:
A punch assembly (1) for producing hollow glass articles in a mold has a punch member (3), which is moved to and from the mold along a straight axis (5) by an electric motor positioned eccentrically with respect to the straight axis (5) and connected to the punch member (3) by a rotary-to-linear motion conversion assembly (20), and a releasable angular connecting assembly (24) interposed between the motor (16) and the motion conversion assembly (20).
摘要:
An apparatus (1) for forming and feeding a molten glass gob (2) has a fixed supporting frame (4); a guide (11) integral with the frame (4) and having a substantially vertical axis (12); a slide (13) fitted in axially-sliding manner to the guide (11); and at least one feed plunger (6) parallel to the axis (12), connected integrally to the slide, and moved cyclically to form the glass gob (2) by a linear electric motor connected directly to the slide (13).
摘要:
In a glassware molding machine (1), the half-molds (5) of a mold (3) are moved between an open position and a closed position and cooled by an actuating and cooling assembly (12) having a fixed supporting structure (13) and, for each half-mold (5), a respective supporting and actuating arm (15) fitted to the relative half-mold (5) and hinged to the fixed supporting structure (13) to rotate about a fixed hinge axis (25a); each supporting arm (15) internally defining a chamber (25) communicating with a ring of cooling conduits (10) formed through the half-molds (5), and the chamber having an inlet (30) formed through an outer lateral wall (31) of the supporting arm (15) to receive cooling air from a compressed-air tank (39) of the machine (1).
摘要:
A timing control system for a hollow glassware production line having a plurality of sections includes a machine controller (42); a plurality of section driving boards (44); a main serial bus (43) interposed between the machine controller (42) and the section driving boards; and a plurality of actuators (48) controlled by the section driving boards (44); the intelligent control operations being concentrated in the machine controller (42).
