摘要:
A machine for moulding hollow glass items comprises a basement (2') supporting a plurality of modules (4') placed side by side, having first and second devices (13, 14) supplying cooling air for parison and blow moulds. A first (VI, 16-22) and a second (V2, 26-31) air supply arrangement supply independently the first and second supply devices (13, 14). Both supply air flows (F1, 15, F2, 25, 25') get independently through each module (4') through the basement (2') and within the module.
摘要:
A mould-supporting system for a machine for forming hollow glassware, comprising: a supporting structure (12); a first carriage (2) and a second carriage (4), which are slidably mounted respectively on a first bar (14) and a second bar (16) of said supporting structure, and carry, respectively, a first mould-carrier arm (6) and a second mould-carrier arm (8); and means (42, 44) for controlling mutual displacement of said first and second carriages between a position where they are set close to one another and a corresponding position where they are set apart. The system is characterized in that, on one between said first and second carriages, means (24) are provided for guiding the other between said first and second carriages during their mutual displacement.

A mould-supporting system for a machine for forming hollow glassware, comprising: a supporting structure (12); a first carriage (2) and a second carriage (4), which are slidably mounted, respectively, on a first bar (14) and a second bar (16) of said supporting structure, and, moreover, are slidably mounted on a third bar of said supporting structure, common to the two carriages, said first and second carriages carrying, respectively, a first mould-carrier arm (6) and a second mould-carrier arm (8); and means (42, 44) for controlling mutual displacement of said first and second carriages between a position where they are set close to one another and a corresponding position where they are set apart, wherein said first and second carriages comprise a first tubular portion that engages, respectively, said first and second bars via first sliding means, and a second tubular portion that engages said third bar via second sliding means. The second sliding means enable adjustment of the position of the second tubular portion in a direction transverse to the third bar.

In a system for supporting moulds in a machine for forming hollow articles made of glass, each mould (8) is associated to an air-distribution body (13) for distributing cooling air within passages (11, 12) made in the body of the mould. Each air-distribution body (13) receives the cooling air from a supply system including a telescopic duct (16), which has its ends connected by means of ball-and-socket joints to a vertical inlet duct (14), fixed to a supporting structure, and to an end duct (15), fixed to the structure of the air-distribution body (13). The system envisages fast-coupling means for connection between the aforesaid end duct (15) and the structure of the air-distribution body (31).

A pusher system for hollow glassware forming I.S. machines comprises at least one pusher device (1) having a stationary structure (6, 7), a movable gripping head (3) and driving means for said head (3). The driving means comprise a kinematic arrangement with articulated arms (10a, 11a, 11b) for supporting the gripping head (3). The kinematic arrangement comprises: - two main arms (10a, 11a) rotatably mounted on said stationary structure (6, 7), rotation of each main arm (10a, 11a) being driven by a respective said motor (15, 18), - at least a third arm (11b) articulated to one (11a) of said main arms (10a, 11a) around a first axis (C), and - a movable structure (10b) for supporting the gripping head (3), articulated both to said third arm (11b) around a second axis (D) and to the other one (10a) of the main arms (10a, 10b) . The main arms (10a, 11a) can rotate around a same rotation axis (A) or around respective axes of rotation (A', A') that are spaced apart and parallel to each other, and the first and second axes (C, D) are parallel to each other and to the axis (A) or the axes (A', A') of rotation of the main arms (10a, 10b).
摘要:
Described herein is a system for feeding glass gobs, for I.S. hollow-glassware forming machines, comprising an extrusion plunger (35) and a cutting unit (38), which are directed by a control unit (12) that controls corresponding servo systems (16, 17) for forming a sequence of glass gobs, there being comprised in said sequence of glass gobs at least one first gob (G1) and a subsequent second gob (G2) having a mass different from said first gob (G1), said control system (12) being configured for directing said extrusion plunger (35) according to at least one first motion profile (P) for extruding said first gob and according to a second different motion profile (P2, P3, P4) for extruding said second gob (G2). According to the invention, said control system (12) is configured for controlling a portion (p2) prior to an instant of cutting (x t , x t2 ) of said second motion profile (P2, P3, P4), imposing that said portion (p2) should determine in the second gob (G2) a mass of glass coinciding with a mass determined, in the second gob (G2), by a corresponding portion (p) prior to a corresponding instant of cutting (x t1 ) in the first motion profile (P).
