Abstract
A device and a method for filling with a gas other than air an insulating glazing unit composed of at least two glass panes and at least one spacer frame, comprising a movable and a fixed bed. The fixed bed is provided with retractable suckers suitable to capture a lower flap of a glass pane and move therewith with a motion of retraction with respect to the movable bed, such as to provide straightening of the lower flap of the glass pane.
Claims11
A device for filling with gas other than air an insulating glazing unit, comprising:
- at least one conveyor that supports and conveys glass panes and spacer frames composing the insulating glazing unit with an arrangement that is slightly inclined with respect to the vertical plane along a longitudinal horizontal axis that is parallel to a base of the insulating glazing unit;
- a perforated manifold that can be throttled in a longitudinal extension thereof and is arranged along a base of the insulating glazing unit;
- a fixed bed that constitutes an extension of the at least one conveyor and is provided with support and conveyance means;
- a movable bed that is movable parallel to said fixed bed and is adapted to capture a glass pane by way of a row of suckers and to keep the glass pane at a distance from a subsequent glass pane provided with a spacer frame supported on said fixed bed for injection of gas fed by said perforated manifold;
- an inflatable tubular gasket, which is arranged longitudinally to, and faces a face plate of said conveyance means, so as to provide a seal between the fixed bed and the movable bed toward the base of the insulating glazing unit suitable to allow gas filling of the insulating glaring unit;
- and
- a sealing system formed by said tubular gasket and a gasket supported on said manifold and said conveyance means formed by a belt conveyor, said manifold and conveyor belt being each movable independently of the other along at least one of:
- respective substantially vertical axes;
- and respective substantially horizontal axes.
A method for filling with gas other than air an insulating glazing unit composed of at least two glass panes and at least one spacer frame, comprising:
- feeding by way of at least one belt conveyor a glass pane on a support and conveyance means, between a substantially vertical fixed bed and a substantially vertical movable bed;
- capturing said glass pane by way of fixed suckers provided on said movable bed;
- feeding a subsequent glass pane provided with a spacer frame on said support and conveyance means so as to rest against said fixed bed;
- capturing a lower flap of said subsequent glass pane by way of retractable suckers provided on a lower band of said fixed bed arranged adjacent said belt conveyor;
- moving said retractable suckers along with the lower flap of said subsequent glass pane by a retraction motion with respect to said movable bed that carries out straightening of the lower flap of the subsequent glass pane to align a lower edge of the subsequent glass pane with said fixed bed;
- and
- injecting gas by way of a perforated manifold in the gas chamber formed by the glass pane and subsequent glass pane.
