摘要:
An assembly (1) for transferring glass articles (5), wherein a powered articulated arm (10) is hinged to a fixed support (2) to rotate about a fixed hinge axis (13), and moves a pusher (18) between an engage position engaging the articles (5) on a supporting surface (3), and a release position to release the articles onto a linear conveyor (7); the pusher (18), in the release position, projects from the articulated arm (10), in the travelling direction of the articles (5) on the conveyor, beyond a plane (25) containing the fixed hinge axis (13) and perpendicular to the travelling direction (9) of the articles (5) on the conveyor, so that the centre of gravity (G) of the group of articles transferred is located downstream, in the travelling direction of the articles (5) on the conveyor, from the plane (25) containing the fixed hinge axis.
摘要:
In a transfer unit (1) for transferring glass articles (2) from a supporting surface to a carry-off conveyor, a pickup member (7), for engaging the articles (2) for transfer, is moved between a pickup position and a release position by an actuating device (7a) having a single articulated arm (8), and two electric motors activated independently to move the pickup member (7) with respect to the articulated arm (8), and to move different portions (9) (10) of the articulated arm (8) with respect to one another.
摘要:
A method and machine (1) for producing hollow glass articles, whereby a mass (6) (11) of glass for shaping is deposited inside a respective mold (3) (3a) and shaped by a shaping air jet fed into the mold (3)(3a); the characteristics of the air jet being varied, during the shaping of the mass (6) (11) of glass, on the basis of a memorized reference time profile (S) (R).
摘要:
A plant (1) for forming glass articles in which an extrusion plunger (13) and a shearing unit (16) are piloted by a control unit (39a) to form a plurality of first glass gobs (3) and a plurality of second glass gobs (4); the first gobs (3) and the second gobs (4) differ from each other at least in their respective weights and are advanced by a gob distributor (8) to respective forming sections (6) (7) which form simultaneously first continuous orderly successions (5a) and second continuous orderly successions (5b) of first glass articles (1 a) and second glass articles (1 b) respectively which differ from each other.
摘要:
A control system (10) is disclosed for controlling a glassware molding machine (1) having a number of forming sections (4), each for successively forming a number of glass articles. The control system has a number of automatisms (10a-10c) for controlling respective actuating mechanisms of the machine (1), which cooperate to form the glass articles; and a central control unit (14) connected individually to the automatisms (10a-10c) and having a processing unit (14b) configured to control and coordinate activation of the actuating mechanisms of the automatisms (10a-10c). The processing unit (14b) is configured to determine the activation times of the actuating mechanisms of the automatisms (10a-10c) on the basis of a desired production plan, and to transmit corresponding control signals to the automatisms (10a-10c).
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:
An assembly (35a) for adjusting the height of a gripping mechanism on a machine (1) for molding glass articles (2) has an upright (10) supporting a gripping head (20) for gripping the glass articles (2), and an actuating assembly (22) for activating the gripping head (20) and, in use, moving the gripping head (20), with respect to the upright (10), between a gripping position gripping the glass articles (2), and a release position releasing the glass articles (2) onto a supporting surface (4); the upright (10) has a bottom connecting portion (23, 30), which is connected to a structure (3) of the machine (1) so as to slide in a vertical direction (29), and the height of which is adjustable by means of a motor (36) located beneath the supporting surface (4) and in parallel with a transmission (55) activated by a crank (51).
