<p>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).</p> |
