Definitions

  • the invention is concerned with the problem of connecting two or more individual glass panes to form an insulating glass pane with the interposition of a metal spacer frame and at the same time sealing the insulating glass pane by means of a hot glue.
  • infrared radiators are used to heat the hot glue, which are arranged on both sides of the double pane (insulating glass pane). Since a system for assembling insulating glass panes must be suitable for the production of insulating glass panes with a wide variety of formats (the edge lengths of the panes typically vary between 0.3 m and 2.5 m in panes produced according to the generic method), one used to the state of the art Technology belonging device a continuous furnace, which has two mutually parallel fields of closely arranged, permanently burning infrared emitters, the size of the fields being adapted to the largest possible disc formats. Between the two fields, the insulating glass panes are heated by diffuse infrared radiation.
  • the working speed of the device consisting of a continuous furnace and a continuous press should not be slower than the speed of the other stations of the production line in which the continuous furnace and the continuous press are integrated.
  • the permanent heat loss must be dissipated, which is expensive.
  • heat-resistant materials have to be used in the continuous furnace, which makes the conveyor particularly expensive.
  • thermal insulation must be used, which the useless radiation, i. H. collect the radiation passing through the insulating glass pane and the radiation passing the insulating glass pane, and finally the heat generated must be removed from the room in which the continuous furnace is installed.
  • the invention has for its object to provide a method that allows to heat the hot glue between the individual glass panes of an insulating glass pane with less installed heating power, with less heat loss and with little equipment and time and then press the insulating glass panes.
  • the invention solves this problem with a method for producing the firm bond of insulating glass panes, the individual glass panes of which are connected by spacer frames coated with hot glue on three sides and at the same time are kept at a distance, by heating the hot glue in the space between the individual glass panes and the side surfaces of the spacer frame by simultaneously both sides Irradiating the insulating glass with heat radiation from elongated heat radiators, in particular with short-wave infrared radiation from elongated infrared light emitters, and then pressing the insulating glass panes to their final thickness as long as the hot glue is still hot, in that the heat radiation is only during one time to heat the hot glue to its working temperature sufficient time interval is generated and bundled and is aimed essentially only at the edge region of the insulating glass panes.
  • the radiant heat is only applied locally where it is needed, as a result of which the radiation duration and the installed electrical power of a person working according to the method Vorrich are low.
  • the heat radiators are only switched on at intervals, namely not longer than the edge of an insulating glass pane between them, the energy consumption also drops sharply compared to the prior art.
  • Radiation types that can be bundled and allow heating up of hot glue strands in reasonable time periods can be considered as heat radiation.
  • Short-wave infrared radiation which is emitted by so-called infrared light emitters, is particularly suitable. Infrared light emitters have the property which is very valuable for the invention, requiring practically no heating-up time when switched on; rather, radiators provide the full heating power almost immediately after switching on.
  • thermal insulation measures can be reduced to a minimum and the ventilation of a device for carrying out the method can be carried out by convection instead of with a ventilation device required in the prior art.
  • the invention therefore no longer uses two fields of heat radiators whose diffuse radiation field is traversed by the insulating glass panes as a whole, but instead linear radiators arranged in a targeted manner from both sides to the edge regions of the insulating glass panes and the position of which constantly changes with the changing pane formats is adjusted.
  • heating of the insulating glass panes is possible both when the insulating glass pane is at a standstill and in a continuous process.
  • the hot-melt strands along the individual spacer frame legs are irradiated and heated as a whole with the disc at rest, ie. that is, in a device operating according to the method, the disks are stopped for irradiation (claim 4).
  • this is not a disadvantage in terms of working speed, because the infrared light emitters available today have power outputs of up to 60 W / cm. this enables the hot glue to heat up to its working temperature within a few seconds.
  • the cycle times resulting therefrom for devices operating according to the method are not higher than the cycle times of other stations in an insulating glass production line with which a device according to the invention must work.
  • a quite simple device through which the insulating glass panes are guided lying or standing on a conveyor, is characterized in that at least two parallel and facing each other, straight-line heat radiators are provided parallel or at right angles to the conveying direction and on both sides parallel to the conveying plane of the insulating glass panes, and that a pair of pressure beams is arranged next to the heat radiators, the pressure beams of which run parallel to the heat radiators, and that at least one pivoting device is provided for pivoting the insulating glass panes by 90 ° (claim 5).
  • the transport of the disks can be done in the usual way, that is, for. B. lying on roller tables or standing on a roller table or a conveyor belt, wherein in the case of standing transport the disks are usually based on a support wall (roller wall, air cushion wall or the like). Because of the smaller footprint, the transport of standing insulating glass panes is preferred (so-called vertical system).
  • the conveying plane of an insulating glass pane is understood to mean a plane lying in the conveyed insulating glass pane and parallel to the pane surfaces.
  • One pair of lamps is arranged so that the incoming insulating glass pane dips with one of its edges into the space between the lamps and then stops. Then the emitters are switched on for a predetermined period of time in which they heat up the hot-melt strand running on this edge of the pane. Subsequently, by moving the disc or the pressure beam, which are preferably coupled to the radiators next to which they are arranged and are jointly displaceable (claim 22), the edge of the disc with the heated hot-melt strand is brought between the pressure beam, for which purpose a displacement path of a few centimeters is sufficient, and the edge of the pane is pressed to the final thickness.
  • the disk After the release of the disk by the press beam, the disk is transferred to a known swivel device, swiveled by 90 ° and brought with the second edge between the infrared radiators by means of the conveyor device. The processes are repeated until all four edges of the insulating glass pane are pressed together. The disc is then removed.
  • the processes are controlled in the usual way by switches which respond to the position of the pane, in particular switches which respond in a contactless manner, and by time switches.
  • the two emitters can run parallel to the conveying direction. Each disc must then be swiveled three times through 90 °.
  • the two radiators are preferably arranged at right angles to the conveying direction; in this case, the two edges of the disks running perpendicular to the conveying direction can first be heated and pressed in succession. The disc is then pivoted through 90 ° and the other two disc edges, which now run perpendicular to the conveying direction, are machined. Overall, only one swivel process is required.
  • radiators running in the conveying direction two or four units can sensibly be used, with radiators running at right angles to the conveying direction, two units of radiators and press beams can be used.
  • each edge of the pane is processed in a different unit; with two units, two opposite edges of the insulating glass panes are processed in the same unit.
  • two units of pairs of radiators and pressure beams can also be provided and arranged in such a way that two edges of each insulating glass pane can be processed at the same time.
  • the units consisting of pairs of radiators and associated pairs of press beams can be arranged at right angles to one another, so that two adjacent edges of the insulating glass panes can be machined.
  • a swiveling process in which the disc is swiveled by 90 ° (claim 8).
  • an arrangement is particularly preferred in which the pairs of emitters and press beams are parallel to one another; With this arrangement, any crossing of radiators in the area of the window corners is avoided.
  • At least one pair of emitters, together with the associated pair of press beams, must be displaceable in parallel, so that adaptation to changing pane formats is possible (claim 9).
  • the displacement of the emitters and pairs of pressure beams can be carried out automatically by sensing the size of each incoming insulating glass pane by means of sensors and using the measurement signal to control a servo drive which carries out the required displacement.
  • two groups of two radiator pairs and press beam pairs can be arranged one behind the other in the transport direction, in a manner analogous to the arrangement according to claims 6 and 7, with a pivoting device for the insulating glass panes in between lies, so that to increase the throughput of the device two disks can always be processed at the same time. If the first two edges of a pane are machined, it is pivoted and handed over to the second group for machining the other two edges, so that the first group can already accommodate the following pane (claim 10).
  • a device for carrying out the method according to the invention through which the insulating glass panes are guided lying or standing on a conveyor device and which does not require a pivoting device for the insulating glass panes, is the subject of claim 11 characterized in that two pairs of mutually parallel and facing each other, rectilinear, arranged on both sides parallel to the conveying plane of the insulating glass panes are provided, of which one pair runs parallel and the other pair perpendicular to the conveying direction, and in that a pair of pressure beams is arranged next to each pair of radiant heaters, the Press beams run parallel to the heat radiators, at least one of the units formed from a heat radiator and from the associated press beam pair being displaceable parallel to itself and parallel to the conveying plane.
  • the device contains only two units made of a pair of press beams and infrared radiators, one of which is oriented in the conveying direction and the other is oriented transversely thereto. If the insulating glass pane first reaches a unit running parallel to the conveying direction, then the pane edge parallel to the conveying direction is first machined, then the unit is shifted to the opposite pane edge (or - in a kinematic reversal - the pane is shifted until its opposite edge is in the effective range of the heat radiators) Press beam unit is) and this processed.
  • the insulating glass pane is then conveyed further and its front edge reaches the effective area of the unit consisting of a pair of heat radiators and a pressure beam that runs perpendicular to the conveying direction.
  • the disc is conveyed on until the rear edge of the disc comes into the effective range of the unit; after processing the rear edge of the disc, the disc is removed.
  • an alternative device through which the insulating glass panes are guided lying or standing on a conveyor, according to the invention, is characterized in that two pairs of mutually parallel and facing each other, rectilinear, arranged on both sides parallel to the conveying plane of the insulating glass panes parallel to the conveying direction and two further such pairs are provided perpendicular to the conveying direction, such that either an insulating glass pane can be machined on all four edges or two insulating glass panes on two edges each, and that a pair of pressure beams is arranged next to each pair of heat radiators, the pressure beams of which run parallel to the heat radiators, wherein at least one of the units formed from a pair of heat radiators and from the associated press beam pair is displaceable parallel to itself and parallel to the conveying plane.
  • the front disk edge is processed first, then the rear disk edge and then the two disk edges running in the conveying direction. If you have the two units connected directly to one another in space, you can even process the rear edge of the disc at the same time with one of the disc edges running in the conveying direction.
  • Such devices require only moderate installed electrical power (claim 12).
  • An increase in throughput can be achieved in such devices working without a pivoting device by arranging two units of heat radiators and pairs of pressure beams in parallel and transversely to the conveying direction in the conveying direction in such a way that two insulating glass panes can be processed simultaneously (claim 13).
  • the arrangement in the quadrant is somewhat more complex than the arrangement of the angular units at such a distance that two insulating glass

  • This can e.g. B. happen that one of the transverse to the direction of the heat radiator pressure beam units shortly before and the other unit shortly behind the two parallel to the conveying direction heat radiator press beam units.
  • the front edge of an incoming insulating glass pane can first be processed.
  • the disc is then transported into the area of the two units parallel to the conveying direction, where the two edges of the discs parallel to the conveying direction are processed. At the same time, the following pane can be processed on its front edge.
  • the first disc is then transported further for processing its rear edge into the work area of the rear heat radiator press beam pair unit, which has reached the heat radiators parallel to the conveying direction and runs transversely to the conveying direction, while at the same time the second disc advances into the working area of the units parallel to the conveying direction and the subsequent one
  • the third disc advances with its front edge into the working area of the front unit, which runs in front of the heat radiators which are parallel to the conveying direction and runs transversely to the conveying direction (claim 16).
  • the two units running transversely to the conveying direction both in front of or behind the two units running parallel to the conveying direction (claim 17). If the transverse to the conveying units z. B. are located behind the units running parallel to the conveying direction, then the two edges parallel to the conveying direction are processed by an incoming insulating glass pane. Subsequently, the front edge of the disk is moved and processed in the working area of the front unit running transversely to the conveying direction, while at the same time the following disk runs into the working area of the units parallel to the conveying direction and is processed there.
  • the first disc then advances until its rear edge lies in the working area of the rear, transverse to the conveying direction, while at the same time the second disc in the working area of the front, transverse to the conveying direction and a subsequent third disc in the working area of the units parallel to the conveying direction advances u. s. w.
  • the two units running transversely to the conveying direction can also be connected to form a compact, higher-level unit (claim 22).
  • an alternative device through which the insulating glass panes are guided lying or standing on a conveyor, is characterized according to the invention in that four rod-shaped or tubular heat radiators are provided on both sides parallel to the conveying plane of the insulating glass panes, at least two of which are parallel to themselves are displaceable in the conveying plane and which together form a square of variable size, and that a press, preferably a static press, is arranged behind the square in the conveying direction.
  • Beam presses, roller presses and roller presses which can be used in the context of the invention, have long been used successfully in the production of an insulating glass type in which the metallic spacer frames between the panes are coated on both sides with a butyl rubber strand.
  • the hot melt adhesives used in the invention after being activated by heating, are considerably softer and less tough than butyl rubber strands. Therefore, the height and the uniformity of the pressing pressure with insulating glass glued with hot glue must be kept under control much more carefully than with insulating glass glued with butyl rubber.
  • the hot glue can in places to such an extent from the space between a spacer and the adjacent glass plate are squeezed out so that there is direct contact between the glass plate and the spacer. However, this must be avoided under all circumstances.

  • a device that can work with a continuous press and through which the insulating glass panes are led lying or standing on a conveyor is characterized according to the invention in that four pairs of mutually facing heat radiators are provided parallel to the conveyor plane, two pairs of which are parallel and two pairs run at right angles to the conveying direction, whereby at least one of the pairs parallel to the conveying direction can be moved parallel to itself and to the conveying plane to adapt to different Isoller glass pane dimensions, that in addition to heat radiators running at right angles to the conveying direction, one each also forms in the form of press beam pairs At right angles to the conveying direction of the pressing beam is arranged, and that a continuous press for the two disc edges running in the conveying direction adjoins the heating zone formed from the heat radiators running parallel to the conveying direction 24).
  • the heat radiators running at right angles to the conveying direction can preferably be moved synchronously with the insulating glass panes in the conveying direction (claim 25) and because a continuous press connects to the heating zone with the heat radiators, the insulating glass panes can also be machined at least partially in one pass, e.g. .

  • Each insulating glass pane 7 is first statically heated and pressed with its front edge in the first vertical unit 3b, then conveyed further in the direction of arrow 2 until its rear edge reaches the area of the second vertical unit 3b and is statically heated and pressed there , while at the same time the front edge of the subsequent insulating glass pane 7 is processed in the first vertical unit 3b.
  • insulating glass pane 7 Downstream of the vertical units are two pairs of horizontal heat radiators 12, of which the upper pair is adjustable in height. Between the heat radiator pairs 12, the two horizontal edges of an insulating glass pane 7 are heated continuously and then pass into a continuous roller press 17 immediately downstream of the heat radiators 12 acts; one part of this belt or roller press is installed stationary in the area of the lower pane edge and the upper part of the belt or roller press is expediently arranged in a height-adjustable manner together with the upper heat radiator 12. If insulating glass panes 7 are machined, the horizontal edges of which are shorter than the horizontal heat radiators, then the horizontal pane edges can of course also be heated statically instead of in a continuous process.
  • FIG. 11 A device similar to FIG. 10 is shown in FIG. 11, but the horizontal heat radiators 12 are arranged at such a great distance from the vertical units 3b that during the heating of an insulating glass pane 7 between the horizontal heat radiators 12 the subsequent insulating glass pane is already heated in the second unit 3b and can be pressed. In total, three insulating glass panes 7 can be processed simultaneously in this device.
  • the continuous press 17 can also be advantageously used for the press quality by means of a statically operating surface press, e.g. B.
  • a plate press 18 can be used as in the example of the following Fig. 12.
  • FIG. 12 shows a device with four pairs of heat radiators 12c-f arranged in the square.
  • a pair of emitters 12c is arranged so as not to be displaceable along the conveyor belt 1 and, with its tips, at which no feed lines emerge, abuts the jackets of a vertically arranged, vertically displaceable pair of emitters 12d; this in turn abuts with its tips, from which no supply lines emerge, against the jackets of an upper pair of radiators 12e, which runs parallel to the conveying direction 2 and can be displaced both horizontally and vertically; this in turn abuts with its tips, from which no supply lines emerge, against the jackets of a vertically, horizontally and horizontally displaceable pair of radiators 12f, which in turn abuts with the tips of the jackets of the lower pair of radiators 12c.
  • This quarters can be adapted to most disc sizes.
  • all four edges of an insulating glass pane are heated at the same time.
  • the emitters 12c-f are switched off and the disk is conveyed to a downstream static press 18, where it is pressed as a whole to its final thickness between two press plates.
  • Fig. 13 shows in detail the section of the arrangement of a double infrared illuminator 12 obliquely to a triple insulating glass pane 7.
  • the mirrored reflector 12 is arranged in a cross-sectionally approximately U-shaped, beveled aluminum reflector 19, which additionally shields the radiator 12 and the Heat radiation additionally bundles on the two spacer frames 8.
  • the opening of the reflector 19 extends right up to the insulating glass pane 7. Because of the oblique arrangement of the radiator 12 with its main radiation direction 21 at an angle of approximately 45 ° to the plane of the insulating glass pane 7, the side surfaces of the two spacer frames 8 facing the radiator 12 can be subjected to heat radiation at the same time will.
  • the emitters 12 are displaceable in the direction of the arrow 20, for displacing the main radiation direction 21, especially when changing from double to triple insulating glass panes, also in the direction of arrow 22 parallel to the pane surface.
  • a radiator 12 of the same type On the opposite side of the insulating glass pane 7 there is a radiator 12 of the same type in a mirror-image arrangement, which has only been omitted for the sake of simplicity.
  • Corresponding devices which are also suitable for producing triple insulating glass panes, can also be realized with units in which heat radiators 12 are used, not the heat radiators 12 arranged on both sides of the panes 7, but the edge joints 10 of the panes 7.
