Patent ID: 7785432

Claim:
Method for positioning glass sheets, that are arranged in pairs one opposite the other, in a vertical assembly and pressing device for insulating glass panes which is part of a production line for insulating glass panes, in which a first glass sheet and a second glass sheet carrying a spacer, intended for an insulating glass pane, are fed into the assembly and pressing device in upright position, standing on a horizontal conveyor and leaning against a first supporting device, the assembly and pressing device comprising an arrangement consisting of two pressure plates that can be transferred from a first position, in which they are inclined in opposite directions, to a second position in which they are positioned one in parallel to the other, by (a) conveying the first glass sheet, leaning against the first supporting device, on a first track of the horizontal conveyor into a predefined first position in which it is stopped; (b) transferring the first glass sheet in a direction transverse to the conveying direction of the horizontal conveyor into a position opposite the first position, in which it stands on the horizontal conveyor in upright position, supported against the second supporting device inclined in a direction opposite to the direction of the first supporting device; (c) conveying the second glass sheet, leaning against the first supporting device into the first position; (d) synchronously conveying the first and the second glass sheets, leaning against their respective supporting devices into a predefined second position on a second track of the horizontal conveyor that can be driven separately from the first track of the horizontal conveyor; (e) repeating the steps (a) to (d) at least once for glass sheets intended for assembly of at least one further insulating glass pane; (f) conveying the glass sheet pairs, standing upright on the second track of the horizontal conveyor, into the opened assembly and pressing device, which latter comprises a third track of the horizontal conveyor that can be driven separately from the second track of the horizontal conveyor; (g) stopping the glass sheet pairs in the assembly and pressing device.
