Definitions

  • the invention relates to a method and a device for the mechanical application of an elastoplastic strip as a spacer on a glass pane, which is intended for assembly with at least one further glass pane to form an insulating glass unit.
  • the spacers between a two or more glass panes comprising insulating glass unit made of aluminum or steel hollow sections.
  • a spacer also referred to as a "swiggle strip" in the form of a strip with a rectangular cross-section, which is provided with protective films, comes from a storage drum or reel and is applied to the glass pane by means of a device equipped with a reversible head.
  • This band-shaped spacer based on butyl rubber is tough-plastic, highly adhesive (which is desirable to achieve a gas-tight connection first with the first and then the second glass pane of the insulating glass unit), and has a highly temperature-dependent viscosity.
  • a method having the features of the preamble of claim 1 is known from US-A-5888341 known.
  • the invention has for its object to provide a method and an apparatus that allow a clean, accurate application of elastoplastic spacer bands.
  • the invention is based on the finding that the quality deficiencies observed when using correspondingly modified, known devices for applying plastic spacer strips are not caused by the electrical control of the device, ie the machine control, but by the material itself in conjunction with the previously known ones Devices usual type of tape transport, which exerts on the tape, albeit small train and / or thrust. While the resulting low elongations and compressions were harmless due to the plasticity of the tape, it was found that the polyurethane-based elastoplastic spacer tape has some form of memory which tends to cause the tape elongated and / or compressed to tend to be bandy, to resume its original length and its original cross-section, this return operation being able to extend with decreasing speed over a period of several hours.
  • the core idea of the invention is to guide the band from the supply drum to the application site free from tensile stresses or shear stresses, regardless of the multiple application rates.
  • the second pair of rollers is best located near the point of application.
  • the equalizing section which is usually arched, acts as a buffer for small over or under delivery of the strip by the first pair of rolls in proportion to the rate at which the second pair of rolls feed the strip to the point of application.
  • the band in the balancing line deviates laterally, transverse to its direction, and thus describes a larger arc.
  • the tape speed during application is not constant but usually (at a rectangular glass) at least four times between zero and a maximum value changes.
  • the slight differences in synchronization which may also occur, inter alia, due to different slippage of the band relative to the first and the second pair of rollers, are compensated by the changes in position of the band guided to a certain extent flaccidly through the compensation section.
  • the tape length in the compensation section is monitored.
  • the speed and thus the peripheral speed of the first pair of rollers is readjusted so that the desired length is reached again.
  • the speed and thus the peripheral speed of the second roller pair is controlled exclusively according to the instantaneous application speed, which depends on the speed of the relative movement between the application tool and the glass pane.
  • the strip length in the equalizing section can be determined in a very simple manner by means of at least one sensor responding to the position of the strip, because the strip moves in the compensating section, transversely to its transport direction, depending on overfeeding or underdelivery.
  • Suitable sensors are known to the person skilled in the art.
  • two sensors can be used in the form of two light barriers, one of which detects the maximum permissible deviation of the strip from the stretched layer and the other the maximum allowable approach to this stretched position.
  • the peripheral speed of the first pair of rollers is increased or decreased in dependence on the determined by means of at least one sensor position of the band in the compensation path, so that the band in the compensation path remains tension-free at least in the vicinity of a predetermined desired position.
  • the band is supported in the compensation path at least substantially without sagging, to prevent the band under the influence of its own weight undergoes elongation.
  • the band can be guided and supported in the compensating section in an arc with a radius that depends primarily on the difference between the peripheral speeds of the first and second roller pairs. This can be achieved in particular by a plurality of guide rollers and guide roller pairs.
  • the band is best supplied by means of an applicator head which can be turned around an axis orthogonal to the plane of the glass pane and on which the first pair of rollers and all subsequent band transport and band guiding devices are arranged.
  • the elastoplastic band can be readily rotated according to the rotational movements of the Applizierkopfes about its longitudinal axis, so that the proposed tape transport and tape guiding devices could be arranged outside the Applizierkopfes with the exception of the second pair of rollers, it is despite the greater design effort for the Applizierkopf better to arrange the tape transport and tape guide devices on this, in order to ensure a tension-free feeding of the tape to the Applizierstelle.
  • the storage drum should generally have a controllable via the machine control drive.
  • a preferred embodiment of this device is characterized in that the balancing section between the first and second roller pair comprises at least one slit-shaped guide for the belt, wherein the long axis of the guide slot is substantially orthogonal to the tape transport direction, and the slot width only slightly larger than the width of the band is.
  • a pivotable lever is expediently arranged at the point of application, which supports the band near the application point, in particular during the turning of the application head.
  • the device for the mechanical application of an elastoplastic spacer strip on a glass comprises a slightly inclined against the perpendicular support wall for the gas disk, a plurality of separately controllable horizontal conveyor in the lower edge of the support wall, at a distance from the support wall a parallel to this column and a slide movable up and down the column supporting an applicator head. All the above parts are known per se, as well as their movements. With devices of this type, inter alia, the edge joints between an insulating glass unit forming glass sheets are filled with sealant or applied plastic spacers. In the drawing, therefore, only the special Applizierkopf for applying an elastoplastic spacer tape is shown.
