Definitions

  • the invention relates to a device for applying the seal and calibrating multiple glazing.
  • the multiple glazings require, for their subsequent mounting in the sliding or articulated frame of frames intended to receive them, to undergo at the time of assembly, with lateral interposition of corrugated frame seals, a pressing-calibration, requiring the application of '' a very high pressure while respecting an accuracy of 0.25 mm.
  • the first consists of pinching simultaneously and sequentially the double or multiple glazing, after interposition of the seals, by exerting on a movable plate, via a cylinder, a force corresponding to the pressure that one wishes to obtain; the calibration being obtained, in this case, by adjustable stops arranged at the four corners of the support table.
  • the second means consists in gradually bringing the glazing closer together, after interposition of the seals, by using several pairs of rollers of the same diameter, with a center distance adjustable individually and collectively, so as to bring, in stages successive, the thickness of multiple glazing to the ideal thickness.
  • roller press offers, compared to the first, the advantage of being easily integrated into an assembly line incorporating a window washing machine and a discharge station automatic, given its continuous operation, the fact remains that the use of rollers requires, given the linear form of the pressure exerted by them on the double or multiple glazing, use a large number of pairs of rollers to reduce the risk of glass breakage, thus performing very gradual calibration. This procedure however complicates the press without completely eliminating the risk of breakage, with all the constraints that these impose on productivity, both by limiting the running speed (4m / min maximum) and by the duration of chain interruptions to eliminate broken glazing.
  • the present invention aims to remedy these drawbacks, by proposing a machine equipped with a pressing and calibration device ensuring regular progressiveness of the calibration and of the pressure during the mounting of the joint (s) of the double or single glazing units.
  • the method of pressing the seal and calibrating multiple glazing units according to the invention mainly consists in ensuring a progressive and regular tightening of the multiple glazing units, while the latter is moving, until a determined thickness is obtained.
  • the tightening pressure is applied in a regular gradient, from the inlet to the outlet of the calibration device.
  • the tightening value can be adjusted according to the initial thickness of the multiple glazing and the calibration that one wishes to obtain.
  • a device allowing the application of this process consists essentially of two endless bands each stretched between two rollers, one of which is kept fixed in position relative to a frame and the other of which is adjustable in position relative to said frame; the active strand of each of the endless bands being kept in contact with a sliding path located between the active and passive strands of each of the bands, in the space left free between the drive rollers of each band.
  • the bearings of the drive shafts of the rollers of the endless belt adjustable in position, as well as the corresponding sliding path, are integral with a chassis adjustable in distance and in inclination relative to the frame of the machine.
  • the tension of the endless belts is obtained by means of a screw and nut system secured to the adjustable frame, and oblong holes made in the fixing lugs of the bearings of the roller shafts.
  • the transverse position, relative to the sliding path, of the entry roller of the endless belt adjustable in position is adjustable by means of a screw and nut system with fine pitch secured to the adjustable frame, allowing to adjust the relative inclination of the two sliding paths, so as to ensure the progressive tightening of the multiple glazing during its movement.
  • the degree of inclination of the two sliding paths relative to each other can be very low, of the order of one to two degrees.
  • the best results have been obtained with a degree of inclination of about one degree and a center distance of 50 to 60 cm between the input and output rollers.
  • the position of the chassis supporting the endless belt adjustable in position and its sliding path is adjustable by means of a system of slides and sliding slides controlled by screw and nut.
  • All the drive rollers of the endless belts are integral in rotation and their drive in rotation is ensured by a system of sprockets and transmission chain.
  • the two endless belts used in the device according to the invention are preferably made of polyvinyl chloride of approximately 3 mm thick, the Shore hardness of which is from 80 to 85: this hardness indeed makes it possible to ensure good pressing while preserving the fragility of the glass.
  • the input and output rollers of the device are preferably provided with a rubber coating of approximately 15 mm thick, whose Shore hardness is from 60 to 70.
  • the advantages obtained thanks to the present invention essentially consist in that the pressing of the seal and the calibration of the multiple glazing are ensured in a regular and precise manner during a relatively rapid scrolling of these, compatible with the productivity of the other means. constituting the whole process. Given its design and its adjustment systems, the device is suitable for automatic remote control combined with that of the other means of the process.
  • This machine comprises a frame 1 supporting on the one hand bearings 2 and 3 adjustable in position by systems of screws 4 and nut 5, in which the shafts 6 and 35 rotate of the input rollers 7 and output 8 ensuring the drive and the tension of the lower endless belt 90, and on the other hand a lower sliding path 10; of frames 11 supporting, by means of slides 13 and 14, of slides 15, 16 and 17, 18, of nuts 19, 20 and 21, 22 and of screws 23 and 24, an adjustable frame 12 supporting on the one hand bearings 25 and 26 adjustable in longitudinal position by a system of screws 4 and nut 5, in which respectively rotate the shaft 27 of the input roller 28 and the shaft 29 of the output roller 30 ensuring the drive and the tension of the upper endless belt 310, and on the other hand the upper sliding path 32; the transverse position of the bearing 25 of the shaft 27 of the input roller 28 of the upper endless belt 310, relative to the upper sliding path 32 being obtained by a system of screws 33 and nut 34 with fine pitch.
  • the shafts 6, 27, 29 and 35 for driving the rollers 7, 8, 28 and 30 are ripe and secured in rotation by means of chain sprockets 36, 37, 38 and 39 and a transmission chain 40 , whose tension and return are provided by pinions 41, 42, 43 and 44, one of which is driven by a motor.
  • the sliding paths 10 and 32 are located between the active strands 91 and 311 and the passive strands 92 and 312 of each of the endless bands 90 and 310.
  • the active strands 91 and 311 of the bottom 90 and upper 310 endless bands are held in abutment against the lower 10 and upper 32 sliding paths; which ensures the application of the seal and the gradual and regular calibration of the multiple glazing during the scrolling thereof by eliminating any risk of bending of the active strands 91 and 311.
  • Adaptation of the device to the number of glazings to be assembled, to the thickness of these and to the final imposed calibration can be obtained very quickly and precisely by action on the screws 23 and 24 for operating the adjustable frame 12.
  • the rotation of these screws can be ensured remotely by means of stepping motors or other similar means, there is therefore nothing to prevent the adaptation of the device and its control being provided by a digital control with adaptation by volume counter in combination with other means of production incorporated into the same process.
  • the device has been described and shown in a horizontal position, but there is nothing to prevent it, for reasons of bulk or incorporation into a process, from being arranged vertically subject to minor adaptations which do not call into question the method and method of construction.
