摘要:
A table (1) for scoring sheets (2) of glass has a supporting structure (3); and a board (4) defining a supporting plane (5) for a sheet (2) for scoring; the board (4) being associated with a peripheral safety barrier (15) extending close to the peripheral edge of the board (4) and at least upwards from the supporting plane (5) to retain the sheet on the supporting plane.
摘要:
A method and assembly for picking up sheets (2) of glass from a pack (3) of superimposed sheets at a storage station (4), whereby the first sheet (2a) in the pack (3) is engaged by a gripping and retaining device (9) and removed from the storage station (4); withdrawal of the first sheet (2a) being performed by performing a first test movement of the gripping and retaining device (9), by determining, as a result of the test movement, a characteristic (P;S;G) of the sheet material (2a; 24) moved during the test movement, by comparing the determined characteristic (P;S;G) with a corresponding reference characteristic relative to the first sheet (2a), and by commanding movement of the gripping and retaining device (9) as a function of the comparison.

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:
A machine (1) for grinding coated sheets of glass (2) has a supporting surface (9) for a sheet (3) of glass for grinding, and two grinding units (10) (11) located on opposite sides of the supporting surface (9); each grinding unit (10) (11) having at least one first grinding wheel (16) for grinding a portion of a peripheral edge (3a) of the sheet (3) of glass, and a second grinding wheel (18) for removing a portion (4a) of the layer of material coating the sheet (3) of glass.
摘要:
A unit (1) for parting a sheet (2) of glass, having at least one notch line (3), has a support (4) for supporting the sheet (2), and a parting device (6) movable about the support (4) and having a movable stop member (13) and a movable pressure member (16), which are located close to an outer peripheral edge (4a) of the support (4) and are of respective lengths (L1)(L2), measured parallel to the notch -line (3), shorter than the notch line (3), so as to only cooperate with a peripheral portion (2a) of the sheet (2) projecting from the support (4); a central control unit (23) being provided to control the movement of the pressure member (16) and stop member (13) as a function of the thickness (S) of the sheet and/or the length (L) of the notch line (3).
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).
