An assembly for controlling the weight of a glass gob on a glassware molding machine has a punch for at least partly penetrating the gob and controlled by a fluidic linear actuator having an outer sleeve of paramagnetic material, and a piston which slides inside the sleeve; the piston being connected integrally to the punch; and movement of the piston being controlled by a linear transducer having a movable member fitted to the piston, and a fixed member located outside the sleeve.

An assembly for transferring glass articles, wherein a powered articulated arm is hinged to a fixed support to rotate about a fixed hinge axis, and moves a pusher between an engage position engaging the articles on a supporting surface, and a release position to release the articles onto a linear conveyor; the pusher, in the release position, projects from the articulated arm, in the travelling direction of the articles on the conveyor, beyond a plane containing the fixed hinge axis and perpendicular to the travelling direction of the articles on the conveyor, so that the centre of gravity of the group of articles transferred is located downstream, in the travelling direction of the articles on the conveyor, from the plane containing the fixed hinge axis.

Method and transfer assembly for transferring glass articles

A push device, for transferring glass articles from an intermediate supporting plate to an unloading conveyor, has at least one seat bounded by two flat supporting surfaces converging with each other and forming between them an angle of over 90&#xb0;, and by at least one further supporting surface adjustable in position with respect to at least one of the two flat supporting surfaces; the article being retained close to a convergence area of the two flat supporting surfaces by a circuit for feeding compressed air between the two flat supporting surfaces.

A push device, for transferring glass articles from an intermediate supporting plate to an unloading conveyor, has at least one seat for housing an article and which is bounded by at least two flat supporting surfaces converging with each other and forming between them an angle of over 90&#xb0;; the article being retained close to a convergence area of the flat supporting surfaces by a circuit for feeding compressed air between the flat supporting surfaces.

In a transfer unit for transferring glass articles from a supporting surface to a carry-off conveyor, a pickup member, for engaging the articles for transfer, is moved between a pickup position and a release position by an actuating device having a single articulated arm, and two electric motors activated independently to move the pickup member with respect to the articulated arm, and to move different portions of the articulated arm with respect to one another.

A method and device for transferring glass articles from an intermediate supporting plate to an unloading conveyor, wherein the article to be transferred is positioned and retained inside a seat on a movable member by feeding compressed air through the movable member; the compressed air being fed in close to an edge of a dihedron formed by two plates of the movable member, and being oriented upwards towards the article to divide the incoming compressed air into two lateral streams laterally and at least partly surrounding the article, and into an upward-directed rear stream.

A transfer unit for transferring glass articles from a supporting surface to a carry-off conveyor, the transfer unit includes a pickup member for engaging the articles for transfer and is hinged to one end of an actuating arm to rotate with respect to the actuating arm about a movable hinge axis under the control of a control unit for adjusting the position of the pickup member independently of the position of the actuating arm.

A punch assembly for producing hollow glass articles in a mold has a punch member, which is moved to and from the mold along a straight axis by an electric motor positioned eccentrically with respect to the straight axis and connected to the punch member by a rotary-to-linear motion conversion assembly, and a releasable angular connecting assembly interposed between the motor and the motion conversion assembly.

In a proportional valve assembly, particularly for supplying compressed air on a glassware molding machine, a tubular body, having an axis and air inlet and outlet ports, houses a slide member which is slid axially along the axis, to open and close the inlet and outlet ports, by a linear actuator, on the one hand, and, on the other, by the reaction exerted by an elastic body and the compressed air; the elastic body being spaced apart from the slide member and connected to the slide member by a relatively moving device.

An assembly for adjusting the height of a gripping mechanism on a machine for molding glass articles has an upright supporting a gripping head for gripping the glass articles, and an actuating assembly for activating the gripping head and, in use, moving the gripping head, with respect to the upright, between a gripping position gripping the glass articles, and a release position releasing the glass articles onto a supporting surface; the upright has a bottom connecting portion, which is connected to a structure of the machine so as to slide in a vertical direction, and the height of which is adjustable by means of a motor located beneath the supporting surface and in parallel with a transmission activated by a crank.
