Abstract:
A device for the attachment of spacer frames (18) to glass panes (5) during the course of the manufacture of insulating glass panes comprises a frame-like holder (8) for the spacer frames (18), the upper, horizontal leg (11) of the frame-like holder (8) being displaceable upwards and downwards. At least two grippers (30) equipped with hooks (50) are mounted to the upper, horizontal leg (11) of the frame-like holder, these grippers being movable to and fro, for the insertion of spacer frames (18) in the device, between a take-over position associated with the end of an overhead conveyor (19) for spacer frames (18) and a delivery position wherein the spacer frames (18) are set into the frame-like holder (8). The hooks (50) are pivotably mounted to the grippers (30) so that they can be moved out of the range of the spacer frame (18) during the return movement of the grippers (30) into the take-over position. Furthermore, lifting members (55) are provided at the lower leg (10) of the frame-like holder. By an upward pivoting of the lifting members (55), the lower leg of a spacer frame (18) is reliably moved onto the clamping means (16).
Abstract:
A spacer frame for insulating glass has corners in which the radii of curvature of the inner wall and the outer wall each are of a larger radius than the side portions of the hollow shaped bar portion. The spacer frame may be manufactured in an apparatus provided for that purpose, having two displaceable bending heads, by first simultaneously bending a hollow shaped bar portion twice through 90.degree., and then further bending it twice through 90.degree. between the corners, wherein, before the operation of bending the corners, the inner wall of the hollow shaped bar portion is curved inwardly and two notches are produced in the outer wall.
Abstract:
An apparatus for fitting spacer frames to panes of glass in the manufacture of insulating glass has a support wall and a frame which is movable towards and away from the support wall and the upper horizontal limb of which can be moved upwardly and downwardly for the purpose of adaptation to the height of a spacer frame, while retractible pins, clamp means and pressure pins for the spacer frame are provided on the frame of the apparatus.
Abstract:
A device for the assembly of insulating glass panes comprises an upright wall equipped with supporting rollers, the lower edge of this wall being provided with driven conveying rollers for glass panes, and a carrier with guide rollers for glass panes movable into or out of the upper zone of the glass panes. The wall can be shifted forward and backward at right angles to its plane by at least the thickness of one glass pane with its spacer frame attached thereto, transversely to the conveying direction of the glass panes. A beam liftable and lowerable underneath the wall carries lifting lugs and guide rollers engaging between the conveying rollers. Furthermore, a measuring device at least partially fixedly mounted on the framework is provided, for example a photoelectric cell, to detect the thickness of a glass pane with its spacer frame attached thereto and to shift the wall backward by this amount.
Abstract:
The invention relates to apparatus for conveying insulating glass panes which are slightly inclined from the vertical and have edge grooves filled with a sealing compound. Pairs of mutually opposite supports are provided, which are moved in the direction of conveyance and have substantially horizontal supporting surfaces and engage the lower edge face of each of the individual glass panes of each insulating glass pane only in an outer portion of the lower edge face. Backing rollers are provided, which are freely rotatably mounted on substantially vertical axes and adapted to engage the insulating glass pane only close to its upper edge.
