Definitions

  • the operation can moreover involve glass sheets of different dimensions, yet belonging to the same "insulating glass pane", in such a way as to obtain a step between the edges of the sheets, which is required in order to enable fitting it to a special type of window, that is, the one forming the so called continuous window paneling or the so called structural windows. And it is indeed these types of "stepped insulating glass panes" that this patent application deals with.
  • the "insulating glass pane” (3) is formed by the composition of two or more glass sheets (1) separated by one or more spacer frames (2) that are generally hollow and drilled with micro holes on the surface facing inwards, such spacer frames containing hygroscopic material in their hollow part and having a butyl sealant on the lateral faces (constituting the so called first sealing) and an air gap (or air gaps) delimited by the glass sheets (1) and by the spacer frame(s) (2) being able to contain air or gas or gas mixes that impart special properties to the double-glazing, for example thermoinsulating and/or soundproofing properties.
  • spacer profile (2) with essentially rectangular section in synthetic foam material (including but not limited to: silicone and epdm) incorporating hygroscopic material in its mass.
  • the joining of the glass sheets (1) and spacer(s) frame(s) (2) is obtained with two levels of sealing, the first having the function of creating hermetic sealing and initial bonding between such components and involving the lateral surfaces of the frame and the portions of adjacent glass sheets already mentioned beforehand, the second having the function of creating definitive cohesion between the components and mechanical resistance of the joining of the components and involving the space formed by the external surface of the spacer frame (2) and the faces of the glass sheets up to their edge (see fig. 1 ).
  • the first level of sealing is replaced by an adhesive, for example an acrylic adhesive, already spread over the lateral faces of the same "spacer profile" (2) and covered with a removeable protective film.
  • the glass sheets (1) used in composing the "insulating glass pane” (3) can have different shapes in function to the use of such pane, for example the external glass sheet (external in respect to the building) can be normal or reflective (to limit heat transmittance during the summer months) or stratified/armoured (against forced entries and acts of vandalism) or stratified/tempered (for safety purposes) or combined (for example reflective and stratified in order to achieve a combination of properties), the internal glass sheet (internal in respect to the building) can be normal or low emissivity (to limit heat dispersion during the winter months) or stratified/tempered (for safety purposes) or combined (for example low emissivity and stratified in order to achieve a combination of properties).
  • the external glass sheet (1M) can be bigger than the internal sheet (or sheets) (1m) for all the extension of the perimeter or only on one side or on some sides (see fig. 1 ).
  • the known technique in fact teaches how to spread the sealant on the surface of the protruding part of the bigger glass sheet (1M) only with manual procedure, using the machine only to extrude the sealant (more frequently a bicomponenent product that therefore must be metered and mixed with the aid of known machines) more or less against such surface (1M) and making use of spatulas (whereby the name “spatula-coating") to manually distribute the sealant, independently from the automatic or manual sealing already carried out in correspondence to the perimeter edge alone.
  • US 4 145 171 discloses a nozzle apparatus for sealing the edges of multi-pane windows, even in cases where the edges are misaligned.
  • the main task of the subject matter of this patent application is therefore that of inventing a device that enables the automatic spreading of the sealant on the portion of the surface protruding out of the bigger glass sheet (1M) in respect to the smaller glass sheet (1m), in particular solving the even greater problem of carrying out the "spatula-coating" also in correspondence to the singular areas of the glass sheet (1) composed of the portions of the sheets themselves where the perimeter band changes direction, for example, 90° in the right angles of rectangular glass sheets (1) or with angles other than 90° in the cusps of polygonal glass sheets (1') or sheets that are otherwise shaped.
  • the same device is moreover able to carry out the "spatula-coating" on curvilinea glass sheets (1'') and (1''') having portions with curvilinea configuration and portions with rectilinear configuration.
  • a device This is achieved by a device according to claim 1.
  • a device Generally it is achieved by extending the known extrusion nozzle (101) with an orthogonal extension (106) composed of a manifold with adjustable extension and in direct communication with a slit (107) from which the sealant destined for the "spatula-coating" exits.
  • the amount of sealant metered by the metering pump of the known sealing machine (10) in addition to filling the space defined between the boundary of the spacer frame (2) and the adjacent glass sheets, must also include the portion defined by the protrusion of the bigger glass sheet (1M) in respect to the smaller glass sheet (1m) with the required coating thickness.
  • the portions described above correspond to areas that, when multiplied by the speed, determine the flow rate of the metering pump.
  • the adjustment of the capacity will be determined by the depth of the spacer frame (2) for the known technique, and also by the extension of the step of the two glass sheets (1M, 1m) for the part relative to the "spatula-coating" regarding the innovative technique.
  • FIGURE 2 illustrates a global view of the device, including the parts [such as the nozzle (101) and the motor (102)] that interface with the known parts of the automatic sealing machine, but excluding such known parts as they have already been described extensively and in detail in the prior patents listed previously.
  • FIGURES 3 to 7 illustate the various processing stages according to which the device (100) spreads the sealant on the internal face of the protruding part of the bigger glass sheet, in particular in the following stages: initial ( Fig. 3 ), intermediate on the first horizontal lower side ( Fig. 4 ), final on the first horizontal lower side ( Fig. 5 ), intermediate execution of the corner between the first horizontal lower side and the second vertical front side ( Fig. 6 ), intermediate on the second vertical front side ( Fig. 7 ), the successive stages constituting a repetition of such illustrated stages.
  • FIGURE 8 illustrates the essential and inventive composition of the device.
  • FIGURES 9 and 10 illustrate the details of the coupling of the device, which is the subject matter of this application, with the details of the known devices of the automatic sealing machine [such as the extrusion nozzle (101), the sealant delivery hose, the feeler for measuring the depth of the spacer frame (2)].
  • the same figures also indicate the control components of the shutter.
  • FIGURES 11 to 14 illustrate the result on the "insulating glass pane" (3) produced, corresponding to the stages illustrated in figures 4 to 7 .
  • the glass sheet (1), the spacer frame (2) and the "insulating glass pane” (3) are identified with one digit numbers.
  • the most frequent situation is indicated with (3), the polygonal shape with (3'), the curvilinear shape with (3''), the mixed shape with (3''').
  • the known components of the automatic sealing machine (10) are identified with two digit numbers.
  • the main components of the new device (100) are identified with three digit numbers starting from the only ones known (101) and (102).
  • FIGURE 15 illustrates an example of the inclusion of the device (100) and the automatic sealing machine (10) in the "insulating glass pane” (3) production line (front view) and does not include: electric/electronic panel, control desk and safety devices.
  • FIGURE 16 illustrates an example of the inclusion of the device (100) and the automatic sealing machine (10) in the "insulating glass pane” (3) production line (plan view) and includes: electric/electronic panel (11), control desk (12) and safety devices, indicated generically with (13) whether mechanical safety guards or optical barriers or laser barriers or electrosensitive mats etc., as, in addition to the functional, qualitative and productive aspects characteristic to the contents of this finding, special attention is also dedicated to the aspects inherent to accident prevention.
  • the electric panel (11) and control desk (12) differ from those of the known technique as regards the implementation of all those commands and controls required to make the device (100), which is the subject matter of this application, operate.
  • the way the "insulating glass pane” (3) is positioned, in particular its initial positioning, is fundamental for the proper operationg of the process carried out by the known part of the head (100), in particular by the known nozzle (101) both in the rectangular version and in particular in the shaped version which shall be dealt with further ahead, as well as for the coordination of the horizontal movement of the "insulating glass pane” (3) and the vertical movement of the vertical carriage, not drawn, bearing the head (100).
  • a sensor detects the position of the margin of the glass sheet and, through the PLC logic (programmable logic controller), supplies the information needed to follow the rectangular perimeter of the "insulating glass pane” to the drives for the horizontal movement of the "insulating glass pane” (3) and the vertical movement of the head (100).
  • PLC logic programmable logic controller
  • the synchronous motor (102) has a further role, not only for shaped "insulating glass panes” (3) but also for “insulating glass panes” (3) with rectangular shape, in combination with the synchronous motor (103) that drives the screw (104), integral by means of the support (105) with the plate (106), the latter being provided with slit (107) and shutter (108) connected to the nut screw (109).
  • the shutter (108) must assume diverse positions with the cylindrical housing and the slit (107) of the plate (106) not only in function to the step between the bigger glass sheet (1M) and the smaller glass sheet(1m) but also in function to the angled position of the head (100) in respect to the "insulating glass pane” (3), as can be deduced from figures 6 and 13 .
  • the sealing head (100) equipped with many components such as the device that reads the step (commonly called "depth") between the edge of the smaller glass sheet (1m) and the external part of the spacer frame (2), the blade that shaves the corners, the sealant delivery hose, the sensors that read the glass sheet, etc.
  • the innovation consists in having added, to the nozzle (101), known and used for extruding the sealant against the peripheral joining for the part delimited by the external edge of the smaller glass sheet (1m) and the external part of the spacer frame (2), an extension formed by the plate 106, constituting an integral part of the nozzle (101), equipped with a slit (107) that can be partialized by means of the shutter (108).
  • slit (107) is placed automatically against the face of the bigger glass sheet (1M), in correspondence to the band that extends out of alignment with the external edge of the smaller glass sheet (1m).
  • the parallelism of the flat face of the plate (106) with the flat face of the bigger glass sheet (1M) is achieved by means of the casing (110) having at least two bushings (111) integral with the same casing and slidling on at least two pins (112) fixed on the known part of the head (100), the casing (110) itself is pushed against the glass sheet by the spring (113), whose reaction is discharged on the known structure of the head (100) where the opening/closing valve of the sealant generically indicated with (117) is also housed.
  • a sliding block spacer (114) in self-lubricating plastic material that protrudes, in respect to the face (106), in a measure equal to the required thickness of the sealant to be spread on the protruding face of the bigger glass sheet (1M).
  • a counter-action wheel (115) supported by a bracket (116) fixed to the known head (100) is conveniently located to counter the force exercised by the spring (113).
  • the function of the synchronous motor (103) carrying out the positioning of the shutter (108) is that of placing the shutter at the point corresponding to the step and keeping it there for all the required length regarding that side, as well as changing the length side per side based on the information coming from the process computer contained in the electric/electronic panel (11) and interfaced with the user by means of the desk (12).
  • the head (100) After terminating the execution of the first lower side (3a) of the "insulating glass pane" (3), the head (100) in its entirety carries out a rotation (90° in the case of the rectangular glass sheet as described before) by means of the action of the synchronous motor (102) and the relative mechanical transmission known.
  • this is only a transitory stage during which the valve (117) is closed more or less before, opened more or less after, in certain cases controlled intermittently, in certain cases with adjustment of capacity, in such a way as to apply the right amount of sealant in corrispondence to the corner perimeter joining.
  • the drives of the motors (102) and (103) act convienently, coordinated by the process computer contained in the electric/electronic panel (11) as described in the next paragraph.
  • the synchronous motor (103) that carries out the positioning of the shutter (108) and the motor (102) that carries out the angled positioning of the head (100) are electric axis interlinked as to change the position of the shutter (108) that must partialize the slit (107) in function to the angular stage, the protrusion of the previously finished side (3a) and the next side to be sealed (3b) and the shape of the "insulating glass pane" (3), the most simple case being the rectangular shape here described.
  • Such correlations are coordinated by the process computer contained in the electric/electronic panel (11) and are interfaced with the user by means of the desk (12).
  • the sealing of the fourth corner (3d/3a) and the relative "spatula-coating" can be carried out simply by effecting the vertical run of the head (100) until the sliding block spacer (114) reaches the margin of the bigger glass sheet (1M) and then effecting a horizontal movement of the "insulating glass pane” (3) until it disengages from the sealing and "spatula-coating" devices and proceeds towards the unloading station of the finished product.
  • a variant of the finding, but inherent practically only to the software and thus using the variants of the same known devices for the sealing part and the same device described for the "spatula-coating" part, is the one costituited by the logic combination of the drives, respectively, the horizontal traslation of the "insulating glass pane” (3), the vertical traslation of the head (100), the rotation of the head (100), by means of the synchronous motor (102), the positioning of the shutter (108) by means of the synchronous motor (103) as to enable the "spatula-coating" on an "insulating glass pane” (3') having a shape other than rectangular being it a regular or non-regular polygonal or on an "insulating glass pane” (3'') having a shape other than rectangular being it curvilinear or on an "insulating glass pane” (3''') having a shape other than rectangular it containing both rectilinear and curvilinear parts.
  • the electric drives of the four motors two for the horizontal and vertical axes known, respectively moving the "insulating glass pane” (3) and the head (100), one (102) for the rotation of the known head (100) and used also for the "spatula-coating", one (103) specific for the adjustment of the shutter, are interlinked by means of electric axis (numerical control).
  • an automatic sealing machine 10 which includes the device for the "spatula-coating", located at the end of the line that produces insulating glass, in respect to which sealing machine the preceding machines (coupling machine and gas filling machine) are located to the left; it is not difficult to imagine a description and relative figures in the case of specular layouts or other different layouts, for example including a change of direction of the line.
  • the sequence of the sealing and the "spatula-coating" of the sides described can be changed based on the global needs of the insulating glass pane production line, cycle time optimizing, alternating of stepped sides in respect to those that are not stepped, etc.
  • a different sequence does not entail changes to the inventive concept but only implies intervention on the software.
