摘要:
A transfer assembly (1) for transferring glass articles (2) from a supporting surface (P) onto an unloading conveyor (4), wherein a pickup member (7), for engaging the articles (2) for transfer, is hinged to one end of a first powered actuating rod (13), and is connected to one end of a second powered actuating rod (14) movable independently of the first powered actuating rod (13) to adjust the angular position of the pickup member (7) about a movable hinge axis (23) as the pickup member (7) rotates between a pickup position and a release position in which the articles (2) are released onto the unloading conveyor (4).
摘要:
A conveyor (1) and method, according to which a glass sheet (2) is selectively moved forward in a longitudinal direction (46) and in a direction (47) transversal to the longitudinal direction (46), by using at least one assembly (9) of wheel conveying units (10) distributed on a horizontal plane (P) and each having a fixed support frame (15), one or more drawing wheels (25) arranged in vertically fixed position with respect to the horizontal plane (P), a first transmission (27) to rotate the drawing wheels (25) about a horizontal axis (22a) parallel to the plane (P), and a second transmission (37) to rotate the drawing wheels (25) about a vertical hinge axis (18) orthogonal to the horizontal plane (P).
摘要:
The edges of a sheet (3) of glass travelling in a longitudinal direction (4) are ground by a grinding assembly (7) having a fixed frame (8); a movable frame (16); a grinding wheel (27); a supporting arm (22) supporting the grinding wheel (27) and fitted to the movable frame (16); and an actuating device (9, 10) interposed between the fixed frame (8) and the movable frame (16), and having a first powered guide-slide assembly (9) for moving the movable frame (16) in a direction (11a) parallel to a longitudinal travelling direction (4) of the sheet (3), and a second powered guide-slide assembly (10) for moving the movable frame (16) with respect to the fixed frame (8) in a direction (13a) perpendicular to the longitudinal direction (4); the grinding assembly (7) also having a locator (28) fixed to the supporting arm (22) and defining a stop to keep the sheet (3) at a distance from the grinding wheel (27); and a compensating device (30) interposed between the supporting arm (22) and the movable frame (16), and having a third guide-slide assembly (23) and a flexible controlled-damping device (31).
摘要:
In a machine (1) for forming glass items, a mold (4) has two half-molds (6, 7) movable between a closed forming position and an open extraction position by a mold opening/closing group (10), wherein two handling arms (8), each connected to a respective half-mold (6, 7), are rotated about respective fixed hinge axes (9) by a single linear actuator (12), the mobile member (19) of which translates in a direction (18) parallel to the fixed hinge axes (9), and is connected to the handling arms (8) by a mechanical transmission having a respective guide-and-slide assembly (19) for each handling arm (8).
摘要:
On a glassware molding machine (1), a molten glass rope (4) travelling in a feed direction (A) is cut crosswise into at least one glass gob (8) by supplying thermal energy to the cutting portion of the rope (4) by means of a heating head (11), so as to locally alter the viscosity of the rope (4) and detach the gob (8).
摘要:
A system (3) for feeding glass sheets (4) to at least one sheet processing line (6) has a sheet withdrawal station (7), in which are housed stands (9) (10) for supporting packs (13) of sheets and a loading machine (7) mobile in a rectilinear transfer direction (8) to withdraw the sheets from the stands (9) (10) and transfer them to the processing line; the stands (9)(10) being arranged along the transfer direction (8) on opposite sides of the loading machine (7) and having first (9b) and, respectively, second inclined side resting surfaces (10b) of the respective sheet pack facing the loading machine (7) and converging one towards the other and downwards, and being mobile from and towards the withdrawal station (7) under the thrust of a common transfer unit (22). A production plant for processing glass sheets uses also said system.
摘要:
The edges of a sheet (3) of glass travelling in a longitudinal direction (4) are ground by an edge bevelling assembly (7) having a fixed frame (8); a movable frame (16); a grinding wheel (27); a supporting arm (22) supporting the grinding wheel (27) and fitted to the movable frame (16); and an actuating device (9, 10) interposed between the fixed frame (8) and the movable frame (16), and having a first powered guide-slide assembly (9) for moving the movable frame (16) in a direction (11a) parallel to a longitudinal travelling direction (4) of the sheet (3), and a second powered guide-slide assembly (10) for moving the movable frame (16) with respect to the fixed frame (8) in a transverse direction (13a) perpendicular to the longitudinal direction (4); the edge bevelling assembly (7) also having a reference locator (50a) which, in use, is positioned against a longitudinal lateral surface (3c), parallel to the longitudinal direction, of the sheet (3); a relative-motion assembly (50) for enabling movement, parallel to the transverse direction (13a), of the reference locator (50a) with respect to the supporting arm (22); and a device (54) for detecting the position of the reference locator (50a) with respect to the supporting arm (22).
