Definitions

  • the invention relates to a method for filling hollow profile strips to be bent into spacer frames with hygroscopic material, in which the hygroscopic material is filled from one end into the hollow profile strip, optionally supported by a carrier gas stream.
  • DE-OS 3 312 764 Another proposal (DE-OS 3 312 764) is to constantly roll the outside of the profile with a pressure roller during the bending process when bending spacer hollow profiles that are filled with hygroscopic material in order to close the hygroscopic material from the corner area oust.
  • the invention has for its object to provide a method of the type mentioned with the hollow profile strips can be filled with hygroscopic material so that they can be easily bent into spacer frames with sharp corners, without the risk that the hollow profile strip during the bending processes in Area of the corners bursts or is deformed, or the hygroscopic material is reduced to dust during the bending process.
  • this object is achieved in that the filling process is interrupted as soon as the hygroscopic material filled into the hollow profile bar reaches a point on the hollow profile bar in which a corner is to be bent that the spacer frame then the Inner wall forming the hollow profile strip is arched, and that the filling of hygroscopic material into the hollow profile strip is continued after arching the wall of the hollow profile strip, and so on until four points of the side wall have been arched in the hollow profile strip.
  • the procedure according to the invention ensures that there is practically no hygroscopic material in the region of the locations of the spacer hollow profile strip which are bent to form the corners of a spacer frame, so that the bending process is not hindered.
  • the arching of the wall of the hollow profile strip which later forms the inner surface of the spacer frame considerably facilitates the bending process, as is known per se from DE-PS 3 223 881.
  • the invention further relates to a device for filling hollow profile strips, which are intended as spacer frames or parts of such spacer frames for insulating glass panes, with hygroscopic material, with a device for filling the hygroscopic material into the hollow profile strip, with a support for the hollow profile strip and optionally with an arrangement to generate a carrier gas stream supporting the filling process, for example a blower.
  • this device is characterized in that an embossing die is provided which, for arching the wall of the hollow profile bar forming the inner surface of a spacer frame, can be advanced to the hollow profile bar lying on the support and can be retracted after a working stroke and with a sensing device assigned to the embossing die , which emits a control signal as soon as the filling level of hygroscopic material in the hollow profile strip has reached the sensing device, that the embossing stamp and the sensing device can be displaced along the support for the hollow profile strip, the at least one drive for the filling head and the stamping die being able to be stopped as soon as the stamping stamp has reached a point on the hollow profile strip in which a corner is formed when the hollow profile strip is subsequently bent to form the spacer frame.
  • the device shown in the drawing has a frame 1 which is placed on a floor 3 via feet 2.
  • the frame 1 has a support 4 for a spacer hollow profile bar 5 to be filled (the hollow profile bar 5 is shown disproportionately thick in order to improve the clarity of the drawing).
  • a storage container 6 for hygroscopic material is provided at the upper end of the support 4, which slopes away at an angle, from which a line 7 extends, which can be closed by a shut-off element 8.
  • the free end 9 of the line 7 projects into the interior of the hollow profile strip 5 to be filled.
  • At least one guide rail 10 is also attached to the machine frame 1 and is arranged parallel to the support 4, above the latter.
  • a carriage 11 is displaceable in the direction of the double arrow 12 parallel to the support 4 by a drive, not shown, which can be designed as a drive with an endless toothed belt, an endless chain, a pinion-rack gear, or a spindle drive.
  • a drive not shown
  • stamping dies can be exchangeably attached to the piston rod of the pressure medium motor 14 in order to be able to adapt the device to different profile shapes and sizes.
  • the carrier 13 carries, on an arm 17 projecting from the support 4, a sensing device 18 which emits a control signal as soon as the fill level of hygroscopic material 19 in the hollow profile strip 5 reaches the sensing device 18.
  • a hollow profile strip 5 is placed on the support 4, having previously been closed at its lower end 20 by a plug 21, e.g. was closed from foam plastic.
  • the embossing die 16 is aligned with respect to the hollow profile strip 5 so that it is arranged at a point in which a hollow profile strip 5 then, after it has been filled with hygroscopic material 19, has a Corner is bent.
  • a spacer frame e.g. the device known from DE-PS 3 223 881 or the device known from DE-GM 87 05 796 can be used.
  • the sensing device 18 which works, for example, on an ultrasound basis, it emits a control signal which is evaluated on the one hand to abort the filling process (the Shut-off device 8 is closed) and on the other hand controls the pressure medium motor 14, whereupon the embossing die 16 advances and creates a trough-like depression 23 in the wall 22 of the hollow profile strip (this is the wall that will later form the inner surface of the spacer frame) by the wall 22 is arched inwards. The stamp 16 is then withdrawn again and the filling process is continued.
  • the embossing die 16 and the sensing device 18 are moved by the drive, not shown, to the next position of the profile strip 5, in which a corner is to be bent (the position shown in the drawing). This procedure is repeated until four trough-like depressions 23 have been embossed in the hollow profile strip 5 and the hollow profile strip has been filled with hygroscopic material up to its end connected to the filling device.
  • the support 4 for the hollow profile strip 5 does not necessarily have to be aligned obliquely.
  • the hollow profile strip 5 can also be arranged horizontally in the device.
