    The invention relates to a method for cutting laminated glass and an apparatus with which the method of the invention can be carried out. For the cutting of laminated glass, various methods and devices are known in the prior art, in which connection, for example, to AT 403 688 B, EP 0 708 741 B, AT 403 908 B, EP 1 475 356 A and EP 1 044 930 A can be referenced.
    Basically, the cutting (parts) of laminated glass is worked so that both glass panes of the laminated glass are scratched and then the cutting lines are opened, for example, by arching, buckling or bending of the glass sheets, followed by the existing between the glass panes composite film (polyvinyl butyral film, PVB- Foil) is separated.
    Known techniques are straightforward for making blanks of laminated glass whose edges are straight and include right angles.
    When blanks of laminated glass were to be made with special shapes, for example blanks in which at least two edges are not perpendicular to each other and / or an edge is bent, it was necessary to manually cut special shapes and reposition the laminated glass at least once.
    In the prior art, when making special shapes bounded by straight edges, with at least one edge oriented obliquely, that is, not perpendicular to the adjacent edge, the laminated glass was manually positioned under a laser indicating the cut line and thereafter the laminated glass (FIG. automatically) cut.
    When blanks of laminated glass were to be made into special shapes with sheets, they were made by hand by means of stencils and hand cutters by first cutting the top and then the bottom glass sheet.
    The invention has for its object to provide a method and apparatus for its implementation, in which when cutting the bearing plate (large format of the laminated glass) and special shapes can be cut, no longer manually repositioned or cut with a template.
    This object is achieved according to the invention with a method having the features of claim 1 or with a device which has the features of independent, directed to the device claim.
    Preferred embodiments of the invention are the subject of the dependent claims.
    In the method according to the invention, it is provided that a bridge (e.g., a positioning bridge) holds the laminated glass (e.g., laminated safety glass, " VSG ") to the cutting table and couples with the laminated glass cutter. Thereafter, the laminated glass cutter and the positioning bridge, which holds the glass, are put into combined movements, which as a result results in a movement of the laminated glass cutter relative to the laminated glass to be divided, which corresponds to the special shape to be produced. With special forms with bends, it is provided that the cutting wheel is guided tangentially to the cut both above and below. This means that the disc with the positioning bridge is moved in both directions and at the same time the laminated glass cutter, so that as a result the desired special shape with a straight edge or edge in the form of a sheet can be produced.
    Further details and features of the invention will become apparent from the following description of a preferred
    Embodiment with reference to the drawings. It shows:
    1 schematically a distribution scheme for laminated glass,
    2 is a schematic sectional view of a two-pane laminated glass (laminated safety glass, "VSG"),
    3 is an oblique view of an apparatus for dividing laminated glass,
    4 shows the device from FIG. 3 in a different view, and FIG. 5 shows a detail of the device from FIGS. 3 and 4 in the area of the laminated glass cutters.
    The blanks designated 1 in Fig. 1 are common blanks in which all edges of the blanks are straight and meet each other at right angles in all corners. The blank 2 in Fig. 1 is a so-called special form, since there includes an edge with the edges lying at its ends another angle (once a sharp, even an obtuse angle) as a right angle.
    Also, the blank 3 in Fig. 1 is a special form, since an edge is not straight but curved.
    Finally, the term special form also the blank 4 understood that has no straight edges.
    The structure of laminated glass 5 (laminated safety glass, " VSG ") schematically shown in Fig. 2 shows that laminated glass 5 has two glass sheets 6, 7 joined together by a plastic film 8, in particular a polyvinyl butyral film.
    For dividing laminated glass 5, it is necessary to score the glass sheets 6, 7 and then to bend the laminated glass 5, once to one side, so that the cut in the one glass sheet 6, and then to the other side, so that the cut in the other glass 7 is opened. Following this, in particular after the two parts have been pulled apart, 4 4 ············ t · 4 · · · · · · · 4 4 ························ The laminated glass 5, which has been obtained by breaking, cut the plastic film 8 (polyvinyl butyral film). To this end, various proposals have been made which use the use of cutting blades, the heating or the insertion of laser beams.
    A device 10 suitable for carrying out the method according to the invention, shown in FIGS. 3 and 4, comprises a cutting table 11 with a horizontal support for laminated glass 5, in which a laminated glass cutter 13 reciprocates (arrow 16) on a bridge 12 fixed relative to the cutting table 11. is movable. The laminated glass cutter 13 has a tool 14 disposed above, and a tool 15 disposed below the laminated glass 5 to be divided (Fig. 5) and an arbitrarily formed device for cutting the composite film 8. The tools 14 and 15 are used e.g. by means of cutting wheels for scribing the upper 6 and the lower glass pane 7 of the laminated glass 5. The tools of the laminated glass cutter 13 are rotatable by drives (not shown) about an axis perpendicular to the plane of the laminated glass 5.
    Furthermore, the device 10 according to FIGS. 3 and 4 has a positioning bridge 20 on which a plurality of stops (not shown) with holding devices 21 (suction heads 22 subjected to negative pressure) are provided for the laminated glass 5 to be divided. The positioning bridge 20 is guided on the edges of the cutting table 11 and can be adjusted by means of a drive, not shown, transversely to its longitudinal extension (arrow 23) along the cutting table 11. This positioning bridge 20 may for example have a structure which is described in EP 1 475 356 A1 for the conveyor 100 shown there in FIG. Any other embodiment of a positioning bridge 20 capable of not only aligning but also holding laminated glass 5, according to the present invention, by moving the laminated glass 5 into blanks during the performance of dividing laminated glass 5, is also contemplated. 5 5 ··· # ·· • · '·· • · "♦ · · • ·« • Ψ' · * · · • · • ♦ * * · · · # ♦
    In carrying out the method according to the invention, the positioning bridge 20 is effectively coupled to the laminated glass cutter 13, so that the movements of Positionierbrücke 20, and thus held by her laminated glass 5 on the one hand, and the movements of the laminated glass cutter 13 along its bridge 12 {cutting bridge) on the other hand matched , and as a result of movement of the laminated glass cutter 13 relative to the laminated glass 5 along the circumference of the desired blank 1, 2, 3 or 4 is achieved.
    By correspondingly moving {arrow 23} of the laminated glass 5 with the aid of the positioning bridge 20 and the method (arrow 16) of the laminated glass cutter 13 along the cutting bridge 12, the laminated glass 5 is divided in order to obtain in particular blanks 2, 3 or 4 with a special shape. Essentially, it follows that the laminated glass 5 by means of the positioning bridge 20 transversely to the longitudinal extension of the cutting bridge 12 moves back and forth (arrow 23) and at the same time the laminated glass cutter 13 along the cutting bridge 12 transversely (arrow 16) to the direction of movement (Arrow 23) of the laminated glass 5 (effected by moving the positioning bridge 20) is moved. By these coordinated and combined movements results in a movement of the laminated glass cutter 13 relative to the laminated glass 5, which corresponds to the outline of the blank 2, 3 or 4 with the desired special form.
    If special forms 3, 4 with at least one bent edge are to be produced with the method according to the invention and the device 10 according to the invention, it is additionally ensured that the laminated glass cutter 13 is rotated during the execution of the bent cut, so that the effective direction of its tools 14, 15 {for example its cutting wheel) is always aligned tangentially to the arc shape of the edge of the blank 3, 4 to be produced.
    Advantages of the method and the invention. Devices are dependent on the embodiment of the invention in the following:
    Special forms 2, 3, 4 are immediately cut when cutting the bearing plate (large-sized laminated glass 5) and do not need to be positioned by hand again or cut with a template.
    The invention allows for special shapes with at least one " leaning " Edge (e.g., special form 2 of Fig. 1). Likewise, the method according to the invention and the device allow special shapes to be produced which have at least one bent edge, for example the special shapes 3 and 4 of FIG. 1.
    A further advantage of the invention is that existing installations and cutting tables can be retrofitted for the production of blanks made of laminated glass (VSG) so that they can carry out the method according to the invention.
    In summary, an embodiment of the invention can be described as follows:
    For splitting laminated glass 5 into blanks with special shapes, a laminated glass cutter 13 with two cutting tools 14, 15 is moved along a cutting bridge 12 fixed relative to a cutting table 11. At the same time, the laminated glass 5 to be divided is moved transversely to the direction of movement of the laminated glass cutter 13 by a positioning bridge 20 on which it is fixed by means of holding devices 21. By a combination of the movements of the laminated glass cutter 13 along the cutting bridge 12 and the laminated glass 5 by means of the positioning bridge 20 in a direction transverse to the direction of movement of the laminated glass cutter (arrow 16) direction (arrow 23) blanks and special shapes with any outline shape without manual intervention and without Repositioning of laminated glass 5 are made.
