Definitions

  • the present invention relates to a multiple glazing with plastic seals according to the preamble of claim 1.
  • Such multiple glazing with plastic seals are known from French patent publications No. 1,439,844, 1,527,165, 2,211,413, 2,287,278, 2,288,069, 2,294,314, 2,294,313, 2,294,140, 2,317,465.
  • the intermediate cord may be a mixture of butyl rubber and polyisobutylene, and the assembly joint may be of polysulfide.
  • double glazing for example, we proceed as follows: the intermediate bead is deposited over the entire periphery of a first sheet of glass, the two ends of the bead are joined together to ensure the continuity of this intermediate bead , a second sheet of glass is applied to this bead, parallel to the first film, a light pressure is applied, and between the edges are sheets of glass thus separated, outside the intermediate bead, over the entire periphery, the putty of the assembly joint, the glazing thus formed is introduced into an oven and allowed to remain there until polymerization of the putty of the assembly joint. At the exit of the oven, the multiple glazing is finished.
  • the glazing obtained is of good quality, the intermediate cord and the outer seal are perfectly bonded to each other on the one hand and to the glass sheets on the other hand, and they complement each other to ensure perfect sealing of the enclosed air space and good resistance to compression, qualities which keep well with aging.
  • these plastic seals give the glazing a flexibility and an elasticity which results in a capacity of said glazing to withstand significant stresses, even when poorly distributed, to withstand vibrations and to accept deformations due for example to expansion.
  • the manufacture of such glazing is expensive.
  • the polysulphide polymerization oven represents a significant investment, it consumes energy and a certain number of glass breakages occur there.
  • the polysulphide used must be rapidly polymerized to limit the residence time in the oven and so that, as soon as they leave, the glazing produced has sufficient compressive strength to be able to be stored stacked.
  • This fast-curing polysulfide is also expensive.
  • the present invention aims to reduce the manufacturing costs of multiple glazing with plastic seals and more particularly glazing comprising a polysulfide seal, by eliminating in the production line of said glazing, the polymerization oven, by using a polysulfide and generally plastics polymerizing at room temperature, at a non-accelerated speed, therefore less costly, but by introducing into said glazing, at the time of their manufacture, spacers of low cost, which preserve the qualities of glazing with joints made of plastic materials, intended to maintain the spacing between the glass sheets until the polymerization is done.
  • the invention as described in claim 1 proposes to introduce in a standing position, in the plastic seals, a reduced number of spacers, practically without thickness, of height equal to the spacing between the glass sheets, of short length compared to the dimensions of the glazing, having a sufficient crushing resistance to maintain the spacing between the glass sheets, as long as the joint or joints are not polymerized, but nevertheless deformable under significant pressures.
  • Each spacer is in contact with each glass sheet of the glazing by a reduced number of points, and preferably by only one or two points, so as to maintain the flexibility of the viou and the ability to absorb vibrations and deformations.
  • these spacers are staples embedded in the plastics of the legs, arranged in said plastics so that the joints of said staples are perpendicular to the plane of the glass sheets.
  • an intermediate cord having on the outside, a tongue, in which the staples are stitched; they thus remain perfectly in place pending the application of the second glass sheet and the injection of the assembly putty.
  • These staples can be put in place by an automatic staple gun, located immediately after the means for laying the intermediate cord on the first sheet of glass, said gun advantageously being controlled by a logic system.
  • these spacers are push pins with a crown head and preferably a plurality of points, said push pins being stitched laterally in the joints and being advantageously placed pressed against and between the two joints.
  • these spacers are spring turns with an axis parallel to the glass sheets.
  • spacers are in small numbers, with reduced overall dimensions, practically without thickness, with limited crushing resistance, so that they do not modify the characteristics of the finished glazings, in particular the characteristics of flexibility, tightness and appearance.
  • Each spacer will have a sufficiently low crush resistance to be able to deform under a reduced weight which will not be more than 3 kg.
  • the invention also relates to methods and to a device for manufacturing such glazing.
  • FIG. 1 shows in section a double glazing with plastic seals for which the invention is particularly suitable.
  • This glazing consists of two sheets of glass 1 and 2 kept assembled at a certain distance from each other by peripheral seals, namely an intermediate bead 3 and an outer seal 4.
  • the spacers are staples 5 in the shape of a U, with legs whose height is equal to the spacing between the sheets of the glass of the multiple glazing.
  • These clips 5 are arranged between the two sheets of glass, preferably parallel to their sides and at the interface of the intermediate bead 3 and the outer seal 4, to remain invisible, to remain protected from corrosion by the seals and to avoid d '' alter said seals in their shape, properties or functions.
  • these staples may have one of the shapes shown in FIGS. 3A and 3B, namely a general U shape with two legs 6 and 7 and a bridge 8 connecting them, preferably of short length, or even better in rounded form to have only a reduced number of contact points or even a single point of contact with the glass sheets.
  • These staples will have sufficient crushing resistance to keep the glass sheets 1 and 2 apart, even in the case of stack storage, pending the polymerization of the outer seal 4.
  • each clip 5 must be deformable under a load of the order of a kilo or which must not exceed 3 kg.
  • the number of clips per glazing and the resistance of each clip can be adapted to the type of manufacture of the vi horrs and glazing stacking mode the main thing is that the glazing after manufacture, before polymerization of the outer seal 4, can be handled and stored without crushing their internal space and that after polymerization of said seal, the staples do not alter not the "flexibility" of the glazing, the seals 3 and 4 then being sufficient to maintain the constant thickness of this internal space themselves.
  • the essential portion of the cord 3, which provides the seal between the glass sheets is absolutely not injured by the stitching of the staples 5 and it can deform during pressing without modifying the orientation of the tongue 20 and at the same time staple time 5.
  • This particular shape is obtained from the section of the intermediate cord 3 by giving the nozzle of the extruder which produces it an appropriate shape.
  • the staples can be put in place using a pneumatic stapler, preferably automatic, placed after the cord extrusion device 3.
  • this stapler is fixed to the head of the extruder, so when in the corners of the glazing, the glazing on the one hand and the extruder head on the other hand are raised to facilitate the laying of the cord and the rotation of the glazing (see French patent publication no. 2 294 140 already mentioned) the stapler is also lifted at the same time as the extruder and therefore does not hinder the movements of the glazing.
  • the triggering of the stapler is controlled by means of a logic system.
  • a cell for detecting the presence of glazing normally exists in a multiple glazing production line, just before the extruder (see French publication No. 2,294,140).
  • a timer relay to take account of the cell-nozzle distance of the extruder and the speed of movement of the glass sheets, this cell triggers extrusion; it interrupts the passage of the rear edge of the glass sheet, possibly with a certain delay.
  • This same cell can similarly initiate the operation of the logic system which controls the stapler, another timer relay then being interposed between the cell and the logic system to adjust the start of stapling according to the position of the cell and the stapler and the running speed of the glass.
  • a detection cell independent of that which controls the extrusion, can be specially provided for controlling stapling.
  • the logic system can be designed to operate the stapler at regular time intervals, for example every 1/2 seconds, which corresponds to a staple every 15 cm in the case where the sheets of glass run at 30 cm / second.
  • the logic system is designed to stop stapling while the glazing is stopped during rotation operations.
  • the position of the first staple is determined on each side of the glazing.
  • the spacers are thumbtacks 9 with a circular head 10, hollowed out in its center, so as to resemble a crown, practically without thickness, of diameter equal to l 'desired spacing between the glass sheets 1 and 2, and with points such as 11, for example three in number, perpendicular to the head 10, of sufficient length to allow a stitching in the thickness of the joints 3 or 4, but despite everything less than the thickness of said joints 3 or 4.
  • a length of the order of 2 mm will be very suitable when the thickness of the joints 3 or 4 is of the order of 3 or 4 mm.
  • thumbtacks 9 will be stitched laterally in the thickness of the intermediate bead 3 by their points 11, then then covered by the mastic of the joint 4.
  • thumbtacks 9 will have the same resistance to deformation as the staples 5, and under load they can mainly deform by ovalization.
  • They can be put in place with the same frequency as staples 5. They can be placed by hand, or preferably with an automatic machine, stitching or tacking them laterally on the cord, machine of the same type and ordered by the same way that the automatic stapler.
  • the spacers are coiled spring turns 12, arranged in the joints 3 and 4 with the axis 13 of the spring parallel to the plane of the glass sheets.
  • the resistance to crushing of these spring turns in the direction perpendicular to the axis 13 must be of the same order of magnitude as that of the staples or push pins.
  • the spacers may remain in the glazing after polymerization of the plastics of the seals, they will no longer be useful, but they will not alter the qualities of the glazing either.
  • the invention has been described by taking as an example multiple glazing having two seals in two different plastics, namely one being a mixture of butyl rubber and polyisobutylene, the other being polysulfide, but it also applies in the case of glazing having a single joint or having more than two joints, whatever the nature of the plastic material which constitutes each joint.
