Definitions

  • the invention relates to a method with - the features specified in the preamble of claim 1.
  • a method is known for example from DE-OS 3 408 688.
  • DE-PS 2 816 437 or DE-PS 2 845 475 the sealing of the corner regions of the insulating glass panes presents particular problems.
  • one or more sealing nozzles are moved along the edge of an insulating glass pane and fill a pasty sealing compound (usually a thiokol) into the edge joint.
  • the sealing nozzles lie against the edge of the two glass panes, which delimit the respective edge joint, and the nozzle opening from which the sealing compound emerges is directed against the spacer, by means of which the two glass panes are glued to one another and which determines the depth of the edge joint.
  • a sealing nozzle is not in the vicinity of a corner of the insulating glass pane, it is not particularly difficult to fill the edge joint evenly with the sealing compound and to achieve a smooth surface of the sealing compound which does not protrude beyond the edge of the glass panes, because the front side of the sealing nozzle has the Edge joint locally covers and the sealant smoothes.
  • DE-OS 3 408 688 proposes three corners of the insulating glass pane cover that edge joint section which adjoins an edge joint section which is being sealed by a sealing nozzle by a cover and scraper plate which is flush with the edge joint section which is just being sealed by the sealing nozzle.
  • the sealing nozzle accordingly moves towards this plate during the sealing process and finally slides with its front side over the edge of the plate lying on the corner of the pane. It is thereby achieved that the sealing nozzle, when it extends beyond the corner under consideration, does not pull out part of the sticky sealing compound adhering to the front side of the nozzle from the edge joint; rather, the sealing compound is stripped through the edge of the plate from the front of the nozzle and retained in the edge joint.
  • the plate prevents a part of the sealant from escaping again at the adjacent edge joint section which is not covered by the sealing nozzle and which would be open without such a plate, when the sealing compound is injected into the edge joint immediately before reaching the corner. So that the plate itself does not pull sealing compound out of the edge joint, it is pulled off the edge of the insulating glass pane.
  • the invention has for its object to provide a suitable for use in automatic sealing devices method for sealing rectangular insulating glass panes, which leads to edge joints that are also completely filled in the corner area, but without leading to a protrusion of sealing compound, so that rework for Removal of such a supernatant is unnecessary.
  • the subsequent edge joint section in the area of the common corner is not covered by a covering and stripping element; Rather, such a covering and stripping element is placed on the edge joint section which is sealed first, after the leakage of sealing compound from the sealing nozzle is interrupted when the corner region is reached and the sealing nozzle from the first Edge joint section was removed; the same sealing nozzle or another sealing nozzle is brought into contact with the adjoining edge joint section in the area of the same corner and begins to seal it starting from the corner, the covering and stripping element lying against the previously sealed edge joint section ensuring that there is a suitable joint in the corner region of the edge joint bubble-free sealing can build up sufficient dynamic pressure without causing an undesired protrusion of the sealing compound at the previously sealed edge joint section.
  • claim 1 demands that the sealing nozzle and the covering and stripping element should cover the edge joint to some extent; this means a cover that is so tight that it prevents the pasty sealant from flowing out, but allows air to pass through, so that the air displaced during sealing can escape from the corner area of the edge joint.
  • sealing can take place in a corresponding manner.
  • a special feature is the sealing of the fourth and last corner of the insulating glass pane, because if the sealing nozzle approaches the last corner when sealing the fourth and last edge joint section, then the other edge joint section belonging to the last corner is already sealed; It would therefore make little sense to proceed formally at this corner as at the other corners and to remove the sealing nozzle from the last sealed edge joint section when it reaches the corner and to apply it to the subsequent edge joint section, because only the area of this last corner has to be sealed. Rather, it is more expedient to leave the sealing nozzle on the last sealed edge joint section for sealing the last corner and to apply the covering and stripping element to the adjoining edge joint section.
  • DE-OS 3 408 688 also describes a corresponding sequence of the sealing process for sealing the last corner of an insulating glass pane, but this does not suggest a planned procedure, as is to be protected by this patent application.
  • the teaching of DE-OS 34 308 688 consists in applying the covering and scraper plate to the adjoining edge joint section each time a sealing nozzle approaches a corner, so that the sealing nozzle against the Edge of the cover and scraper plate runs.
  • the teaching of DE-OS 34 308 688 there is even no covering and stripping plate at all, because it is the corner that never ends, but only the starting point of the sealing process for both in this corner coinciding edge joint sections.
  • the invention also differs from the prior art formed by DE-OS 3 408 688 in that when all four corners of the insulating glass pane are sealed, the sealing nozzle rests with respect to the insulating glass pane while it fills the covered corner area of the edge joint with sealing compound, and in that only then is the covering and stripping element removed from the edge of the insulating glass pane.
  • the prior art on the other hand, only sealing compound emerges from the sealing nozzle as long as it is moved relative to the insulating glass pane, and since this movement is essentially uniform, it is hardly possible to exactly in the corner region of an insulating glass pane exactly the amount required to completely fill the edge joint Apply sealant, especially if the edge joint is particularly deep due to the use of curved spacer frames.
  • the corner area of the edge joint is sealed with a stationary sealing nozzle
  • the delivery capacity of the pump delivering the sealant to the sealing nozzle assumed to be constant
  • the control commands required for this can be derived, for example, from a predetermined control program.
  • sensors are state of the art, for which reference is made to DE-OS 3 217 410.
  • the procedure is preferably such that the sealant emerges from the sealant.
  • tion nozzle shortly before the sealing nozzle reaches the end of the edge joint section, so that the strand of the sealing compound does not extend directly to the end of the edge joint section.
  • Another advantage of this procedure is that there is initially a larger free space in the corner area of the edge joint, which can be filled more easily but without protrusion when the corner area is subsequently filled with a sealing nozzle that is stationary relative to the insulating glass pane, than if, as in the prior art, this additional one There would be no free space.
  • the sealing of the first edge joint section of an insulating glass pane preferably begins shortly after the beginning of this edge joint section.
  • the distance at which a strand of sealing compound ends before the end of an edge joint section must be matched to the length of the covering and stripping element in such a way that the covering and stripping element completely covers the remaining space in the edge joint section.
  • the covering and stripping element could first be brought into its covering position, in which it rests on the edge of the insulating glass pane in the already sealed edge joint section, and could then bring the sealing nozzle into contact with the adjoining edge joint section.
  • the covering and stripping element is intended to abut the front of the nozzle, it is more favorable to first bring the sealing nozzle into its sealing position in which it rests, and then to bring the covering and stripping element into its covering position in which it is applied hits the front of the nozzle.
  • the procedure is such that the covering and stripping element is first applied to the edge of the insulating glass pane at a distance from the front of the sealing nozzle and then allowed to slide along the edge until it abuts the sealing nozzle.
  • This ensures on the one hand that the sealing nozzle and the covering and stripping element seal the corner region of the edge joint together tightly; on the other hand, the covering and stripping element, while sliding along the edge of the insulating glass pane, can have a smoothing effect on the sealing compound which has already been filled in.
  • insulating glass panes can be sealed in any position.
  • Devices in which the insulating glass panes are sealed horizontally (DE-OS 2 309 295, DE-OS 2 845 475, DE-OS 2 907 210) or those in which they stand on a horizontal conveyor and against are suitable for carrying out the method, for example a support device can be sealed leaned (eg DE-OS 2 816 437 or DE-OS 2 846 785), provided that the necessary covering and stripping elements are provided there and ensures a process sequence according to the invention.
  • a tool arrangement consisting of a sealing nozzle and a covering and stripping element, in which the latter is arranged on a carrier which follows the movements of the sealing nozzle, for example in such a way that the covering and stripping element and the Sealing nozzle are arranged on a common carrier.
  • the covering and stripping element should only be placed in the corner area at the edge of the insulating glass pane, it is expediently displaceable on its support both at right angles to the level of the insulating glass pane and in the plane of the insulating glass pane. This makes it possible to keep the covering and stripping element at a distance from the insulating glass pane while the sealing nozzle moves relative to the insulating glass pane.
  • the covering and stripping element consists of a part intended for bearing against the edge of the insulating glass pane and a spring which can be deflected at an acute angle, and can be deflected at its distant end, at the protruding end of which an actuating device for the covering and stripping element acts transversely to its contact surface, the Tip of that acute angle is directed against the sealing nozzle.
  • the covering and stripping element can be act as a sheet from which an arm is cut out and bent to form an acute angle, or an angular sheet formed in another way.
  • This design has the advantage that the covering and stripping element resiliently moves to the edge of the insulating glass pane when it is moved against the edge of the insulating glass pane with the actuating device, which can be a pneumatic piston-cylinder unit, for example applies and at the same time - due to the resulting reduction in the acute angle - glides along the edge of the insulating glass pane until it abuts the front of the sealing nozzle. In this way, the desired tight coverage of the corner area of the edge joint is achieved with the least effort.
  • the actuating device which can be a pneumatic piston-cylinder unit, for example applies and at the same time - due to the resulting reduction in the acute angle - glides along the edge of the insulating glass pane until it abuts the front of the sealing nozzle.
  • Another advantage of using an angle plate as a covering and stripping element is that it can twist somewhat if it is sufficiently soft and also comes into contact with the edge of both individual glass panes of the insulating glass pane if their edges are not exactly aligned. It is even better, however, to ensure that the covering and stripping element is pressed more strongly against the glass edge over which it is last pulled during the respective stripping process.
  • the covering and stripping element rests with sufficient pressure on both glass pane edges, so that the glass pane edge protrudes less far no sealant is pulled out of the edge joint; rather, the covering and stripping element is cleanly stripped off on the outer edge of the less protruding glass pane edge.

  • the sequence of movements of the sealing nozzles and the covering and stripping elements does not change if the insulating glass pane is sealed horizontally.
  • the elements that support, support and move the insulating glass pane are state of the art; they have been omitted from the drawings for simplicity since they are not required to understand the invention.
  • the insulating glass pane is formed by two individual glass panes which are connected to one another by a spacer frame 2 glued in between them.
