Abstract
The present relates to a device and a procedure for the extrusion and application of a spacer profile of insulating glass, particularly for a machine adapted to compose the spacer frame directly against one or more glass panes constituting the insulating glass starting from a thermoplastic product prevalently contained in drums, displacing the extrados thereof to an adjustable and controlled distance referred to the margin of one or more glass panes.
Claims12
A device for the extrusion and application of a spacer profile of insulating glass, comprising at least one feeler located upstream of an extrusion nozzle that identifies a position of a margin of a glass pane and transmits a position signal to a controller which, through axes H, V, ϑ, driven by synchronous motors, actuates a keeping of a mutual position of the nozzle and margin of the glass pane at a distance p which is set through an operator interface.
A device for the extrusion and application of a spacer profile of insulating glass wherein an extrusion nozzle, through mechanisms comprising:
- an actuator;
- a mechanical transmission;
- a support;
- an actuator/compensator;
- a connection to slide;
- and a transducer, all located in a synchronous carriage;
- a sensor, located in an extrusion head, interfaced with one another and operating in connection with an ubication of a perimeter face of a glass pane, during a relative movement of the nozzle, the extrusion nozzle following an actual position, not a theoretical position, of such face along a transverse axis Z, with control of force applied by the nozzle against the face of the glass pane in perimeter portions in which the pane receives the extrusion of the spacer profile.
A procedure for the extrusion and application of a spacer profile of insulating glass, comprising keeping a mutual position of a nozzle and margin of a glass plate at a constant distance p, which is set through an operator interface, chasing an actual position of the margin of the glass pane, which may be different from a theoretical geometric position, so that a peripheral cavity identified by inner faces of the glass pane and a spacer profile is homogeneous along a complete perimeter of the insulating glass, and filling with a secondary sealant performing structural bonding and gas and water vapor tightness functions.
