Definitions

  • the invention is based on a method for producing perforated, frame-shaped spacers filled with a desiccant for edge-sealed insulating glass by bending and / or plugging together hollow profile bars.
  • spacer frames of hollow profiled bars which usually consist of Afuminium or steel to start to cut them into pieces of suitable length, to be filled with a granular drying agent, at the ends with foam plug to close, and with corner connectors, which are inserted into the ends of the cut hollow profile bars to form rectangular frames.
  • spacer frames for edge-glued insulating glass in one piece from a single hollow profile bar which is bent at right angles to form the frame corners at four points in such a way that the two ends of the hollow profile bar then face one another and can be connected to one another, for example by inserting a connecting element, through which the hollow profile rod is closed at the same time.
  • the hollow section bar In a modification of this method of production, it is also possible to bend the hollow section bar to form the corners only at three different locations by 90 °, in such a way that the two ends of the hollow section bar then meet in the area of the fourth corner of the frame, where they are closed and connected by a corner connector that is inserted into the ends of the rod.
  • the hollow profile bars are provided with a perforated wall from the start, namely that wall which in the later spacer frame represents the inner wall.
  • the perforation is necessary so that when the insulating glass pane is assembled, the desiccant can absorb and bind the moisture contained in the interior of the insulating glass pane.
  • Molecular sieves in the form of free-flowing granules are usually used as drying agents.
  • each spacer frame must be used to form an insulating glass pane as soon as possible after its completion, because if it were stored for a long period under normal ambient conditions, it would absorb and bind moisture from the air and then in the insulating glass pane, in which it is installed, can no longer absorb any more moisture or insufficient moisture to reliably prevent fogging of the inside of the insulating glass pane. It is therefore customary to immediately coat the finished spacer frames on both of their side surfaces (the flanks) with an adhesive (usually a butyl rubber) and immediately insert them between two glass plates that are bonded together by the adhesive. It is also common to fill a remaining edge joint of the insulating glass panes, which is delimited by the two individual glass plates and the outer wall of the spacer frame, with a sealing compound (usually a thiokol).
  • an adhesive usually a butyl rubber
  • the invention has for its object to enable a more flexible, more rational and therefore less expensive manufacture of spacer frames. This object is achieved by a method with the features specified in claim 1.
  • the connecting elements with which the abutting ends of the hollow profile bars are connected to one another are usually fixed and at the same time sealed by injection of an adhesive.
  • the adhesive used is usually the same adhesive with which the spacer frame is also coated on its two flanks at a later point in time.
  • weld or solder the hollow profile rod ends lying in a joint of the frame can also be used in the method according to the invention.
  • spacer frames which have not yet been perforated and which have been produced according to the invention can be used further for installation in insulating glass, they must first be perforated so that the desiccant can develop its intended effect in the insulating glass pane.
  • This necessary perforation occurs according to the invention only shortly before the frames are installed between two glass panes, preferably in connection with the coating of the frames with an adhesive, since this coating is also usually carried out shortly before the frames are installed.
  • a frame is preferably perforated simultaneously with its coating with an adhesive.
  • the advantage of the invention is that it is now possible to manufacture and temporarily store spacer frames. This is particularly efficient because you no longer need a separate device or system for frame production for each individual insulating glass assembly line, but more than one insulating glass assembly line can be operated with a single such system.
  • the work sequence - when producing the spacer frames no longer has to be coordinated with the production program of an insulating glass assembly line, rather one can produce spacer frames from mutually identical hollow profile bars for longer periods than before and also over longer periods than before to produce frames with mutually identical dimensions, which means that Output a device or system for the production of spacer frames is considerably enlarged because dead times, which are required to convert the system to changed hollow profile bars and changed frame sizes, largely disappear.
  • the claims 4-6 contain suitable devices for performing the method according to the invention.
  • An endless belt which is moved over a flat surface, is particularly suitable as a stand-up conveyor for the spacer frames.
  • this device For perforating the frame leg resting on the stand-up conveyor, this device has at least one roller which can be pivoted out of an ineffective position, in which it does not engage in the running plane of the frame, and an effective position, in which it rests on the frame leg resting on the stand-up conveyor is.
  • This roller is provided on its circumference with radially projecting thorns which penetrate into the wall of the lower frame leg and perforate it. So that the force that the mandrels need to penetrate is not too great, it is advisable to use hollow profile bars, the wall of which is weakened in a longitudinal strip. Such training is possible without difficulty, if you manufacture the hollow section bars, as is customary, by extrusion.
  • the required contact pressure of the roller provided with mandrels can be achieved by means of the pivot drive of the roller, and preferably by means of a pneumatic or hydraulic piston-cylinder unit.
  • a spiked roller is preferably attached in the vicinity of a pair of mutually facing nozzles arranged on both sides of the erecting conveyor, which nozzles are used to coat the two flanks of the frame leg resting on the erecting conveyor with an adhesive.
  • the frame is rotated - by hand or with an automatically operating swiveling device - by 90 ° and then the frame leg now lying below is perforated and optionally coated with the adhesive, and this is repeated until all four frame legs are perforated. Thereafter, the perforated spacer frame is installed as soon as possible in an insulating glass pane, the manner of installation not being the subject of the present invention.
  • the perforation of the spacer frames could also be accomplished by means of one or more needles going up and down, which act on the wall of the respective frame leg to be perforated.
  • the drive of such a needle could take place in a similar manner as is known in sewing machines, the drive of the needle being driven by the drive-up conveyor, with which the frame leg under the needle. is promoted, would be synchronized.
  • Such a needle with its associated mechanics like a roller provided with spikes, should be able to be swung out of the running plane of the spacer frame.
  • the accompanying drawing shows schematically and partially in cross section a device for coating spacer frames on both sides, which is also equipped with a roller for perforating the spacer frames.
  • the drawing shows a vertically cut ab stand frame 1, which stands on a horizontally conveying stand-up conveyor 2 and is leaned against a support wall 4, which is inclined a few degrees against the vertical.
  • the conveying direction of the erecting conveyor 2 is perpendicular to the plane of the drawing.
  • Both the stand-up conveyor 2 and the support wall 4 rest on a frame 3, the mechanical elements which establish the connection between the frame 3 and the stand-up conveyor 2 and the support wall 4 being omitted because they are not important for the understanding of the invention are.
  • Two nozzles 12 for coating the flanks 5 and 6 of the spacer frame are arranged opposite one another on both sides of the stand-up conveyor 2, spaced above the stand-up conveyor in such a way that the nozzle openings lie precisely against the flanks 5 and 6 of the bottom of the stand-up conveyor Frame legs 1a are directed.
  • roller 9 which can be swiveled up about an axis parallel to the installation conveyor 2 from a position in which it rests on the upper side of the lower frame leg 1a to a position which lies outside the running plane of the frame 1.
  • This roller is provided with spikes 10 which protrude radially from the roller and are evenly distributed along the circumference along a circular line.
  • the device contains at least one other role, however without mandrels, which is arranged pivotably in the same way as the roller 9, is not driven, but is free-running and serves to ensure a slip-free transport of the spacer frame 1 on the stand-up conveyor 2.
