Definitions

  • the invention relates to a device with the features specified in the preamble of claim 1.
  • Such a device is known from DE-OS 23 10 502.
  • the two glass sheets to be connected are clamped together with a spacer in the form of a bracket or bellows and standing on a horizontal conveyor and leaning against a support roller field with their respective lower edges passed over a stationary nozzle from which a hot-melting material emerges and enters as a strand into the intermediate space between the two glass sheets and bonds with its two mutually counter überlie g edges.
  • the pair of glass panels is pivoted as a unit by 90 ° about an axis perpendicular to the plane of the pane, and then a strand in the edge region which is now below injected from the hot-melting material.
  • rollers are provided on both sides of the disk running plane, which exert a slight pressure on the outer surface of the two glass sheets at the moment the hot-melting material is injected, in order to keep the distance constant throughout.
  • the two glass sheets to be connected have to be clamped together before the injection of the hot-melt material with the interposition of a spacer, and that this spacer has to be removed from the hot-melt material again before the last strand is injected.
  • a rational, automatically running connection of two glass panels is not possible in this way.
  • a further disadvantage of the known device is that the pair of glass panels clamped together has to be rotated three times by 90 °, since this requires a pivoting device which, particularly in the case of larger glass panel formats, has to be constructed in a complex manner, quite apart from the fact that a relatively large amount is required for pivoting glass panels Time and space needed.
  • the invention has for its object to provide a device of the type mentioned, in which a rotation of the glass panels is not required and which are in a special way for a rational, automated connection from glass panels to insulating glass panes.
  • the horizontal conveyor has separate supporting elements for supporting the two glass sheets over one of their large surfaces, one of which defines the plane of the pane, while the other defines a plane parallel to it.
  • the pane running plane is understood here to mean a plane parallel to the glass sheets, which coincides with the outer large area of one of the two glass sheets when the glass sheets are transported on the horizontal conveyor, and in the case of transported glass sheets the lower large area of the lower glass sheet, and in the case of a horizontal conveyor which the glass panels are transported standing and leaning against the support elements, the large rear surface of the rear glass panel.
  • the horizontal conveyor known from DE-OS 23 10 502 also has supporting elements for the large rear surface of the rear glass panel.
  • the front glass panel is supported by the spacer firmly clamped between the two glass panels.
  • the invention now uses separate support elements which are arranged on the horizontal conveyor in such a way that they define a plane parallel to the plane of the disk running, whereby they hold the second glass sheet at a predetermined distance from the first glass sheet lying in the disk running plane, while the two glass sheets are conveyed synchronously on the horizontal conveyor and / or are connected to one another by injecting an initially pasty and subsequently solidifying material into the space between them.
  • hot-melt adhesives or thiocols are suitable as materials for this.
  • a nozzle is provided according to the invention, which can be moved parallel to the plane of the disk running transversely to the transport direction of the horizontal conveyor.
  • one nozzle can be used, but several nozzles can also be provided, which are used one after the other or partially at the same time for injecting the pasty mass into the space between two glass sheets. If several nozzles are provided, then at least one of them can be moved in the manner described.
  • nozzles and their movements including those in which a nozzle can also be moved in the transport direction or counter to the transport direction of the glass panels in order to be able to seal the edges of resting glass panel pairs parallel to the transport direction are described in DE-PS 28 16 437 and DE-PS 28 46 785; they can be transferred to the present invention insofar as they act on insulating glass panes which are not pivoted during processing.
  • both nozzles start their work simultaneously or approximately simultaneously at a first common corner and end simultaneously or approximately simultaneously at the opposite corner, so that the two strands generated by them are connected to each other at both ends as long as they are still fresh (hot), whereby a tight connection of the two strands can easily be achieved.
  • the support elements for the glass sheet arranged at a distance from the pane running plane can be brought out of engagement with this glass sheet individually or in groups by an actuating device. You can use this actuator easy to control automatically if you provide sensors that provide information about the position of the respective glass panel pair and the nozzles. In that edge area of a pair of glass panels, in which the initially pasty and then solidifying mass is already injected, this mass can take over the necessary support of the glass panels arranged at a distance from the plane of the pane instead of the already disengaged Ao support elements.
  • a spacer which dips into the intermediate space between the two glass sheets and which keeps the two glass sheets at the necessary distance in the vicinity of the nozzle openings and which ensures that the one injected between the glass sheets is provided at a constant distance ahead of the nozzle openings of the nozzles
  • the strand of pasty mass has exactly the required width, which corresponds to the distance between the glass sheets.
  • the weight of the upper or front glass panel which is arranged at a distance from the plane of the pane running, can already ensure that the glass panels are lying or inclined.
  • pressure elements in particular rollers, are preferably provided on both sides of the spacer, by means of which the two glass sheets are pressed against the spacer during the injection of the pasty mass.
  • the invention is applicable both to devices with a horizontal conveyor on which the glass sheets are transported lying, as well as on devices with a horizontal conveyor on which the glass sheets are transported standing.
  • a suction device that is movable parallel and transversely to the disk running plane is expediently provided in such a device, for example a suction plate, which can be placed on the upper glass sheet in order to compensate for its sagging by suction.
  • the suction device is therefore designed to be movable parallel to the plane of the pane in order to be able to bring it approximately in the middle of the glass sheet in the case of changing formats of the glass sheets.
  • rollers which plunge into the space between the two glass sheets and roll on the inside of the glass sheet which is arranged at a distance from the plane of the pane. It is not one required that the rollers are completely immersed in the space between the two glass panels; it is sufficient if they do so with part of their scope. Tapered rollers are particularly suitable for this purpose, they only enter the space between the glass panels with the larger part of their circumference in diameter and can still be used even with small distances between the two glass panels.
  • pins could also be used to support the glass panel arranged at a distance in front of the plane of the pane, which plunge into the space between the two glass panels.
  • these pins should consist of a material with a low coefficient of friction or should be drivable synchronously with the horizontal conveyor.
  • the support elements are rollers, they can be designed to run freely, but it is also entirely possible to design them to be drivable so that they can contribute to advancing the glass panels on the horizontal conveyor.
  • the support elements it is not necessary for the support elements to support the glass sheets over a larger area of their respective large area, rather it is sufficient to support the glass sheets only at their edge, in particular on those two edges which run in the transport direction of the horizontal conveyor.
  • the support of the glass plate which is arranged at a distance from the plane of the pane, is preferably two for the transport direction of the horizontal parallel lines of support elements, in particular of support rollers, of which at least one line can be displaced parallel to the plane of the disk running transversely to the direction of transport in order to be able to adapt the device to changing formats of the glass sheets.
  • a lower row of support elements which only protrude slightly above the installation level of the horizontal conveyor and a second row of support elements which are arranged such that they can be adjusted in height, the support elements of the lower row preferably being used can be lowered below the level of the horizontal conveyor.
  • the distance of the support elements for the front or upper glass panel from the pane running plane can preferably be changed.
  • the pressing elements which are arranged on both sides of the spacer, can be acted upon in the simplest case by mechanical springs.
  • a pneumatic piston-cylinder unit or a similarly operating actuating device is preferably provided, which makes it possible to press the pressing elements against the glass panels at will and to lift them off at will.
  • such an actuating device also enables adaptation to different insulating glass pane thicknesses. Because even with different insulating glass the outside of the one glass sheet is always in the pane running plane, there is no need to arrange the pressing elements lying in the pane running plane with the pressure exerting surface, although it can be advantageous to store them with limited displaceability, in particular flexible.
  • the opposing pressure element (s) can be displaced transversely to the plane of the pane.
  • the piston rod of the piston-cylinder unit is connected to the pressing element (s) on one side and its cylinder to the pressing element (s) on the other side of the disc running plane (flying connection), expediently for the pressing elements, the Pressure exerting surface should lie in the disc running plane, only provides a small displacement path, but a larger displacement path for the opposing pressure elements.
  • the nozzle and the spacer assigned to it can be separate components, but the two are preferably arranged on a common support; in particular, the nozzle itself can be the spacer. Since the spacer is in contact with both glass plates and is moved relative to the glass plates when the pasty mass is injected, it is expedient if the flanks of the spacer are made of a plastic with low friction coefficients exist. In addition, it is expedient if the spacer is chamfered in order to facilitate its insertion into the space between the two glass sheets.
  • the nozzle In order to produce a strand from the pasty mass between the two glass sheets, it is not always necessary to allow the nozzle to be immersed in the space between the two glass sheets; the device known from DE-OS 23 10 502 also shows a non-immersing nozzle. Preferably, however, the nozzle is immersed in the space in such a way that the nozzle opening is opposite to the direction of relative movement of the nozzle with respect to the glass sheets. Such an arrangement is favorable for the production of a uniform, straight line.
  • the nozzle, the spacer (if the nozzle is not itself the spacer) and the pressing elements are arranged on a common carrier and are displaceable and pivotable therewith.
  • a two-layer composite strand is preferably produced from two different components, the two layers extending from one to the other glass sheet and the first layer consisting of a material which, although adhering to the glass sheets, is not water-vapor tight and contains a granular drying agent (for example Molecular sieves), which is able to bind moisture present inside the insulating glass pane, whereas the second, outer layer contains no desiccant and instead seals the interior of the insulating glass pane against the external atmosphere in an absolutely tight manner.
  • a granular drying agent for example Molecular sieves
  • the two outlets are to arrange openings or the outlets of the two feed channels in the alternatively provided one outlet opening of the nozzle in relation to the direction of movement of the nozzle relative to the glass panels;
  • the two outlet openings of which are opposite to the direction of movement of the nozzle relative to the glass panels the two outlet openings are naturally oriented such that they are adjacent to one another at the same distance from the plane of the pane.
  • a horizontal conveyor which has two in a row Has separately drivable sections, the support elements arranged in the first section of the horizontal conveyor for the large area of the glass sheet lying at a distance from the pane running plane being adjustable separately from those in the second section, and the first section of the horizontal conveyor together with its support elements for the two glass sheets being perpendicular in one direction is adjustable to the disc running plane.
  • the two glass sheets to be connected can be brought to cover at a predetermined distance and then jointly transferred to the second section.
  • An example of the first section of the horizontal conveyor is described in DE-OS 28 20 630. The mode of operation will be described in detail later with reference to the accompanying drawings.
  • the best way to inject the pasty mass into the space between the two glass sheets is to use a nozzle which is movable and progressively pivotable by 90 ° in the claimed manner, or two nozzles, one of which can be displaced in the claimed manner and is progressively pivotable through 90 °, while the other is arranged at the level of the stand-up conveyor and is only intended to produce a strand along the lower edge of the glass sheets.
  • This one nozzle or these two nozzles can be arranged between the two sections of the horizontal conveyor mentioned in the previous paragraph.
  • the first section of the horizontal conveyor expediently has two separate, parallel, side-by-side, optionally separately or jointly drivable stand-up conveyors for the two glass panels to be covered, which convey the two glass panels separately in succession and bring them to a distance; the two glass sheets can then be transferred together into the second section of the horizontal conveyor.
  • Such stand-up conveyors are described in DE-PS 30 38 425 and in DE-PS 34 00 031.
  • Such a stand-up conveyor can be used with advantage both in one embodiment of the device according to the invention with only one nozzle and in one embodiment with two nozzles.
  • an advantageous further development of the invention provides that the horizontal conveyor above the erecting conveyor has at least one auxiliary conveyor which can be driven synchronously with the erecting conveyor and which acts on the edge the glass panel or on the outer large surfaces of the glass panels and thereby pushing or pulling the glass panels in addition to the stand-up conveyor.
  • Pushing in the transport direction (x) could be effected by a stop acting on the rear edge of the glass sheets, pushing against the transport direction (x) by a stop acting on the front edge of the glass sheets, which, if required, moves from an inactive position behind the pane running plane into a effective position can be advanced or swiveled.
  • an auxiliary conveyor is provided which acts on the outer large surfaces of the glass sheets, in particular one which is formed by suction conveyors arranged opposite one another on both sides of the disk running plane. These can be suction plates, which are placed on the two large outer surfaces of the glass panels and the glass panels in addition haul to the driven stand-up conveyor synchronously with it.
  • suction conveyor belts such as those in the older German patent application P 35 29892.8 and in the German patent application filed by Mr. Karl Lenhardt on the same day as the present patent application with the title "Device for the slip-free conveyance of piece goods in any position, in particular in inclined or iw vertical position "are described.

  • five such conveying members 80 and 81 are arranged in the sub-station 2b for each of the two glass sheets 31 and 32 in the transport direction, which support jaws 82 and 83 with surfaces parallel to the plane of the disk run 10 for bearing against the glass sheets 31 and 32.
  • every second conveyor link 80 and 81 supports supports 46 and 45, respectively, in such a way that the front conveyor link 80 does not support any supports when the opposite rear conveyor link 81 supports support 45, and vice versa.
  • the supports 45 and 46 protrude so little beyond the jaws 83 and 82 that they do not reach the edge joint formed between the two glass panels 31 and 32.
  • the distance between the front supports 46 and the rear supports 45 can be changed in order to adapt to insulating glass panes of different thicknesses.
  • An example of such promotional songs and their drive is described. is in DE-PS34 00 031 /.
  • a useful similar horizontal conveyor with opposing supports in pairs is described in DE-PS 30 38 425.
  • the sub-station 2b has two auxiliary conveyors 70a and 70b which are the same as the sub-station 2a and which extend at least over part of the length of the sub-station 2b, starting from their inlet end.
  • the auxiliary conveyors 70a and 70b preferably extend over the full length of the sub-station 2b, in the example of FIGS. 8 to 16 there are two auxiliary conveyors in succession, each of which is as long as the auxiliary conveyors 70a and 70b in the first sub-station 2a.
  • a support wall which is preferably designed as an air cushion wall and for this purpose has holes distributed over its surface, from which air flows out, which creates an air cushion between the support wall and the glass panels being conveyed, on which the glass panels float.
  • the second sub-station 2b of the sealing station 2 is followed by a removal station 84, the construction of which largely corresponds to the construction of the second sub-station 2b, but does not have the auxiliary conveyors 70a and 70b or the upper support roller row 11.
  • the nozzle 36 has two feed channels 51 and 52, which run obliquely towards one another in two closely adjacent, parallel, elongated off outlet openings 53 and 54 open, which are opposite to the direction of movement of the nozzle relative to the two glass panels 31 and 32.
  • Different pasty materials can be fed through the two feed channels 51 and 52, which connect at the outlet of the nozzle to form a composite strand 67 consisting of two layers 65 and 66.
  • the separating surface between the two layers 66 and 67 runs transversely to the pane running plane 10 from one glass sheet 31 to the other glass sheet 32.
  • the nozzle 36 is dimensioned a little narrower than the predetermined distance between the two glass panels 31 and 32, so that it can be immersed in the space between the glass panels. So that the two glass panels 31 and 32 in the nozzle area exactly maintain the required distance, the nozzle openings 53 and 54 are preceded by a spacer 55, which in the example shown consists of a slide shoe 56, which is attached to the nozzle body and its flanks exactly the predetermined distance to have.
  • the slide shoe 56 is made of a material which has a low coefficient of friction compared to glass. The fact that it is attached to the nozzle body means that it can be easily replaced if necessary due to wear due to friction. So that the spacer 55 can be easily inserted into the space between the two glass panels 31 and 32, the slide shoe 56 is provided with a chamfer 68 at the edges with which it dips into the space between the glass panels.
  • Two free-running pressure rollers 57 and 58 are provided on both sides of the spacer 55, the axes of rotation 59 and 60 of which are arranged parallel to the disk running plane 10. These pressure rollers 57 and 58 press the two glass sheets 31 and 32 against the spacer 55 and thereby secure their predetermined spacing, so that the composite strand 67 can be produced in the required width that corresponds to this spacing.
  • the pressure rollers 57 and 58 are mounted in a carrier 50 which is displaceable in the direction perpendicular to the pane running plane 10 and which embraces the edge of the glass sheet pair 31, 32 in a bow shape. Since the rear glass sheet 32 in the horizontal conveyor 3, on which the nozzle 36 is arranged, always has a constant position determined by the disk running plane 10, there is only a very small displacement path of perhaps only 0.5 for the pressure roller 57 mounted behind the disk running plane 10 mm required. For the opposing pressure roller 58, a larger displacement path is provided for adaptation to insulating glass panes of different thicknesses.
  • the axes 59 and 60 of the two pressure rollers are connected to one another by a pneumatic piston-cylinder unit 62, 63, for example in such a way that the piston rod 63 with the axis 59 of the rear pressure roller and the cylinder 62 with the axis 60 of the front pressure roller connected is.
  • the two pressure rollers 57 and 58 are thus actuated together by the piston-cylinder unit 62, 63 connected to them in a floating manner.
  • the pressure rollers 57 and 58 are at their greatest distance, after immersion they are pressed pneumatically against the two glass sheets.
  • the nozzle 36 When the nozzle 36 is moved around the corners of the glass panels 31, 32, the nozzle body only partially slides out of the space between the two glass panels; As shown in Fig. 7, the portion of the nozzle 36 remains in which. the outlet openings 53 and 54 are located between the glass panels 31, 32.
  • the nozzle 36 can be pivoted about an axis 37 running perpendicular to the disk running plane 10, which is close to the outlet opening 54 which is the deepest in the space between the two glass panels 31 and 32 .
  • the position of the axis of rotation 37 is also selected such that it lies approximately in the alignment of the surface 69 of the resulting verbuna strand 67 facing the interior of the insulating glass panes; the pivoting of the nozzle 36 takes place from a position in which the axis 37 is at the same distance from the two adjacent edges of the insulating glass pane formed from the glass panels 31 and 32 (see FIG. 7); this ensures that a capillary formation of the composite strand 67 is obtained in the corner region of the insulating glass pane.
  • the spacer 55 slides out of the space between the two glass panels 31 and 32 when approaching a window corner; this means that each time the nozzle 36 is pivoted, the pressure rollers 57 and 58 must first be removed from one another and, after pivoting, must be moved toward one another again in order to press the glass panels 31 and 32 again against the spacer 55.
  • the nozzle 36 like the pressure rollers 57 and 58, is attached to the carrier 50 and, together with the latter, can be pivoted about the axis 37.
  • the carrier 50 in turn is attached to the carriage 34 (Fig. 1); the carriage 34 itself cannot be pivoted.
  • the nozzle 36 is arranged on the carrier 50 so as to be adjustable in the direction perpendicular to the plane of the pane 10 (part 64). To adapt to different distances between the glass panels 31 and 32, the nozzle 36 can be exchanged for wider or narrower nozzles.
  • the process of assembling an insulating glass pane in an assembly line which works with only one nozzle 36 is described below with reference to FIGS. 8 to 16.
  • the sequence up to the positioning of two glass panels 31 and 32 congruently at a distance in the pairing station 1 has already been described further above, so that the following description can take its starting point in FIG. 9.
  • the two glass plates 31 and 32 positioned in the pairing station 1 are moved together into section 4 of the horizontal conveyor, which is located in the first sub-station 2a of the sealing station, and rapidly into section 41 of the horizontal conveyor transferred to the sealing station in the second sub-station 2b.
  • the frame 8 is moved back to its starting position (as in FIG. 8), so that the first glass sheet of the next pair of glass sheets can enter there.
  • the pair of glass panels 31, 32 is advanced by the horizontal conveyor 41 to a position in which the glass panels 31 and 32, with their rear, top-to-bottom edge, lie in a predetermined position in the space between the horizontal conveyors h 4 and 41; this position is shown in FIG. 11.
  • the device 33 brings the nozzle 36 to the lower rear corner of the glass panels 31 and 32, dips into the space between them and moves up the rear edge of the glass panels to the rear upper corner and progressively produces a strand 67 of initially pasty mass between the two glass sheets 31 and 32 from bottom to top.
  • the upward movement of the nozzle 36 is stopped and, as shown in detail in FIG. 7, in a clockwise direction swiveled by 90 °.

  • the two glass sheets 31 and 32 are along the lower edge by the lower support rollers 11 in the horizontal conveyor 4 and by the auxiliary conveyors 70a and 70b, on the rear edge and on the upper edge in the area between the rear upper corner and the nozzle 36 by the strand 67 already generated, and in the area from the nozzle 36 to the front upper corner by the spacer 55 associated with the nozzle 36 and by the upper support rollers 12 in the horizontal conveyor 41.
  • the backward movement of the glass sheet pair 31, 32 continues until it reaches the position shown in FIG. 13, in which the nozzle 36 has reached the front upper corner and the front edge of the glass sheets 31, 32 at a predetermined position in the area between the horizontal conveyors 4 and 41 lies.
  • the nozzle 36 With the glass plate pair 31, 32 at rest, the nozzle 36 is now pivoted again clockwise by 90 ° and then moves down along the front edge of the glass plate pair until it reaches the lower front corner of the glass plate pair (FIG. 13).
  • the nozzle 36 is pivoted a further 90 ° clockwise and the pair of glass plates 31, 32 is then moved forward in the direction of the arrow x while at the same time injecting the pasty mass into the space along the lower edge of the glass plates, which in turn enter the area of the horizontal conveyor 41 and are taken over by the latter.
  • the glass panels 31, 32 can run into the horizontal conveyor 41 over their full length without a stop, since the sealing process is ended when the lower lower corner is reached by the nozzle 36 and the nozzle is automatically closed.
  • the nozzle 36 is now rotated a further 90 ° clockwise and is now ready to seal the next pair of glass plates, which has meanwhile run into the horizontal conveyor 4 (FIG. 15).
  • the sealed insulating glass pane formed from the glass panels 31 and 32 is rapidly conveyed from the second sub-station 2b of the sealing station into the removal station 84 and stopped there (FIG. 16).
