    [0001] The present invention relates to the field of breakage of a glass sheet, more particularly to the breaking of a complex shape in a glass sheet. To achieve such a break, two operations follow one another: - a preliminary operation of tracing one or more surface cracks on the surface of the glass using, for example, a glass wheel or a laser; these cracks form lines at the contours of the form; this operation is called the "cut" operation; an operation for propagating the initial surface crack through the thickness of the glass sheet; this operation is called the "break" operation and allows to separate the shape that we want to cut from the original glass sample, called primitive. There are currently two techniques for breaking glass, depending on the complexity of the volume to be cut: For simple shapes with straight edges not penetrating inside the form (no concavity on the shape), it is possible to use a rectilinear inverse breaking technique, illustrated in Figures 1 a & 1 b. This involves making a straight cut through, that is to say from one edge to another (Fig.1a), then to put the entire crack in extension by lifting the glass sheet along the entire length of the crack, by means of a bar (Fig.lb) or one or more point contacts.
    [0002] Nevertheless, this method does not allow to cut complex shapes. For forms of non-rectilinear contours, one works from a sheet of glass of dimensions larger than the shape to be cut. This leaf is called primitive and generally has the shape of a trapeze. The different cutting steps are illustrated in Figure 2a - 2d.
    [0003] We start from a primitive having the shape of a square (Fig.2a), a rectangle or a trapezium. For example, using a glass wheel, draw the outline of the shape to be cut (Fig.2b). Additional cuts in the form of straight segments are disposed at the periphery of the shape to be cut. These segments are called additional features and allow a good break of the part of the primitive located outside the shape to be cut. A multi-step rom page of the primitive part located outside the cut-out shape leads to obtaining different pieces called "falls" around the complex shape to be cut (Fig.2c). The shape to be cut is then isolated from the falls of the primitive (Fig.2d). In the case of cutting complex shapes described here, the breaking is performed by a technique of local bending of the initial crack by pressing on the fall or by grasping the fall. The bending is done by a lever arm mechanism by pressing the glass sheet, outside the shape and in a limited number of points, on a hard or soft coating. FIGS. 3a to 3d are diagrams in section of the breakage of a glass sheet 15 by flexing an initial crack of complex shape using a bending of the outside part to the shape to be cut out . Figures 3a and 3b relate to the case of breaking on a flexible mat. A force is applied on the fall by support until rupture and separation of the fall.
    [0004] In Figures 3c and 3d, this is the example of breaking on a hard carpet. The glass sheet is placed cantilever so that a force applied to the drop by support or gripping, allows to deform the glass sheet until rupture. Nevertheless, these techniques have several disadvantages.
    [0005] In the case of FIGS. 3c and 3d, there is a loss of a sacrificial glass surface necessary for canting during the break. In addition, there may be problems with the cutting quality of the complex shapes, because when we apply a support on the drop, it is generally not possible to create a bending stress at any point on the cutting line. . This is particularly the case for the re-entrant shapes (concave on the shape to be cut). In this case, it is possible to bend the glass at the entrance of the concave part, but as soon as the crack has spread a little, and before we could lift the tool that exerts the support, the stress field in crack head is modified by the geometry of the cutting line. The pure flexion exerted at the beginning of the concave part is quickly transformed into shear stress and generates scales. In the case of shapes with small radius, the crack can propagate outside the initial cutting line and generate scrap. This situation is shown diagrammatically in FIGS. 4 and 5. An adjustment of the support points can solve this problem but it remains a difficulty. Moreover, this results in a limitation of the complex shapes that can be achieved, particularly in the case of geometries with small concave radii of curvature (deep curved zones) where it is difficult to properly place a fulcrum. These difficulties make the breaking of the concave shapes particularly delicate. If the radius of curvature is small, the adjustments of the positions and the efforts of the points of support become long and delicate. In production, the breaking of these 15 geometries is often sensitive to the slightest variation of working parameters and can generate many rejects. Moreover, the propensity of the stress field at the crack head to change from a pure bending mode to a shear mode is exacerbated when the glass thickness increases. The re-entrant shapes are thus deemed very difficult to perform for thick glass of 3.85 or 5 mm. An object of the invention is to facilitate the cutting of complex shapes in glass sheets. For this purpose, the subject of the invention is a process for breaking a complex shape in a glass sheet, comprising: a step of tracing a cutting line on the surface of the glass, by means of a tool cutting; - A step of breaking by means of a local support means applied opposite face and facing the cutting line, the local support means being moved and supported along the cutting line, on said opposite face; - Support means-plane cut line side, facing the local support means during the breaking step. This method makes it possible to reduce the area of sacrificial glass between two volumes. It is even conceivable to cut several pieces from a large glass sheet with pieces that can be touched at certain points. We can then consider cutting with a maximum nesting of shapes and a very significant reduction of falls. Indeed, it is not necessary to create a primitive square, rectangle or trapezoidal shape close to the complex shape to obtain. It is possible to cut the complex shape directly into the large format sheet in which several complex shapes can be cut. This allows an optimization of the positions of the complex shapes in the glass sheet, and thus a reduction in the cost of the raw material "glass". It is also possible to create primitives some of whose edges are ready to shape and of complex shape while the shaping of the other edges is performed during the second cutting step. In general, it is a question of realizing all or part of the complex-shaped edges from the first cutting step on the production line. It is still possible to shape all the edges during the second cutting step, that is to say to continue to cut at first primitives whose edges are not ready to shape, but by providing smaller "trim" widths than before. More complex cuts may also be made, particularly "re-entrant" cut-outs and for thick glasses, and with good performance. Since the position adjustment is linked to the contour, adjusting the position of the supports is also easier. In addition, this breaking technique can be integrated on an existing line.
    [0006] According to particular embodiments, the method also has one or more of the following characteristics, taken alone or in any technically possible combination: the local support means is mounted rolling to roll on the glass sheet; - The local support means is a ball or a roulette preferably rounded; the local support means is applied with a support force chosen as a function of the local radius of curvature of the shape to be cut; - The local support means is applied in continuous support along the cutting line; The local support means is applied with a force having at least one periodic component; the method uses a suction table for plane support means, the suction table carrying the glass sheet by suction of the upper face of the glass sheet, during the step of breaking or cutting; the method is used to cut at least two interleaved and / or tangential complex shapes in the same glass sheet. The subject of the invention is also a process for manufacturing a plurality of complex-shaped glazings from a large-sized rectangular float glass sheet having at least one dimension corresponding to the width of the float glass ribbon from which it is produced using the method of any of the preceding claims for cutting at least a portion of said glazings. According to a particular embodiment, the manufacturing method comprises: on a first cutting station of said glass sheet, a step of tracing at least one cutting line corresponding to at least one edge ready to shape glazing, a first step of breaking, on a second cutting station, a step of tracing at least one cutting line corresponding to at least one other edge ready to shape glazing; a second breaking step. According to particular embodiments, the manufacturing method also has one or more of the following characteristics, taken alone or in any technically possible combination: the precision of marking the cutting lines on the first cutting station is +/- 0.2mm; the second cutting station incorporates a precise focusing step at +/- 0.1mm; on the first cutting station, the cutting line is a rectilinear line crossing the glass sheet from one edge to the other; - on the first cutting station, the cutting line forms an edge ready to shape several windows on the same side of the cutting line; - On the first cutting station, the cutting line also forms an edge ready to shape several windows on the other side of the cutting line; - On each side of the cut line, the edges ready to shape are the same edge of the glazing; - On each side of the cutting line, the edges ready to shape are the opposite edges of the glazing; the first breaking step forms a primitive for each glazing unit to be manufactured, the second breaking step forming the glazing unit ready to shape; the method comprises at least one additional cutting station, with at least one additional breaking step; the method comprises, after the second breaking step, a step of shaping the glazing; - shaping is a grinding; two grinding steps are carried out; the large-format glass sheet has at least a dimension of at least 2.9m. The invention also relates to a machine for breaking a complex shape in a glass sheet, comprising: - a cutting tool and means for automatically moving said tool to make a cutting line perpendicular to the surface of the glass on a first face of a glass sheet; - A local support means and means for automatically moving the local support means and / or the glass sheet relative to the other, the machine being configured to apply the local support means against the opposite face of the first face of the glass sheet and move it opposite and along the cutting line so as to break the complex shape; - a planar support means against said first face of the glass sheet, opposite the means The invention will be better understood on reading the description which will follow, to be made solely by way of non-limiting example, with reference to the following figures: FIGS. schematic views in vertical section of different steps of a method according to a particular embodiment of the invention - Figures 7a-7c, 8a-8c, 9a-9c and 10a-10c are also schematic views in vertical section steps performed by four break-in machines 11a and 11b illustrate an example of a cutting design permitted by the invention according to a first example of a production line, the white lines representing the edges along their contour ready to be shaped and the dashed lines the drawing of the lines. cutting during the first cutting step on the line. Figures 12a and 12b are views similar to Figures 11a and 11b for another example of a production line. Figures 6a-6c schematically illustrate a method according to a particular embodiment of the invention, consisting first of all in a step of drawing a line 2 (or "line") of cutting, that is to say of creating a crack on a first face 4A of the glass sheet 4, followed by a reversal step of the glass sheet, for a posterior step of local support facing the crack, on the opposite face 4B to the first face. The drawn cut line corresponds for example to the contour of the complex shape to cut, without additional features. Note that throughout the text, "complex shape" means a curved line, or succession of lines, at least some of which are not rectilinear, or straight lines with changes of direction forming at least a concave portion. Two nested forms mean that a convex part of one encroaches into a concave part of the other, ie the outline of the two forms can not be separated by a straight line. By two tangent forms are meant that they have a common part at their contour. Also note that the sheet of glass to be cut is flat. The tracing of the cutting line is for example carried out by means of a glass wheel 6 or any other suitable cutting instrument, such as for example a laser. The cutting line 2 is a crack intended to allow the breaking along this line during the breaking step. It is therefore a partial cut, i.e. only on a part of the thickness of the glass sheet. This is what is meant by "cut line" throughout the text.
    [0007] With this method, as explained above, it is possible to remove all or part of the additional features according to the method of the prior art. Indeed, the additional lines may only be necessary to open the contour in order to extract the shape and no longer to facilitate the breaking of the complex shapes.
    [0008] As illustrated in FIG. 6c, the first face 4A of the glass sheet 4, on which the cutting line 2 has been made, is pressed on a plane bearing surface 8. This is for example a soft carpet. The deformability of the flat bearing surface 8 is chosen so as to control the stress field exerted by the local support means. Mastering the stress field makes it possible to control the propagation length of the crack. The goal is that the crack propagates to a predetermined length depending on the shape to be cut. The length chosen for the crack will be smaller if the local radius of curvature is small. If the crack propagates too fast, the surface should be chosen less deformable or the pressure of support weaker. If the crack propagates too slowly, it will be necessary to choose a more deformable surface or a greater pressing pressure. For a sheet of standard silico soda-lime glass of "Planilux" type with a thickness of 3.15 mm, the parameters were as follows: Cutting parameters: 25 Wheel: angle 150 °, width = 1 mm, diameter: 5 mm Speed displacement wheel: 100m / min Force exerted on the glass = 50N Penetration wheel in the glass: 4 / 100mm Glass thickness: 3,15mm 30 Parameters of inverse fracture: Tool of rupture: type wheel, diameter: 5mm, width: 1mm Speed of movement tool: 30 m / min Force exerted on the glass = 70N 3024136 - 9 - Hardness coating of the flat support means: hard felt mats: 45-52 shores The local support means 10 is for example a ball of any suitable type, or other local support means of any suitable type, for example a wheel, preferably a toric wheel. The ball has for example a diameter of 1 mm. As a variant, the diameter is chosen of any suitable type, in particular up to 10 or even 20 mm. The local support means 10 is preferably chosen rigid, for example steel or a suitable plastic material.
    [0009] The local support means 10 is moved along the cutting line over the entire length of the cutting line, preferably by exerting a continuous resting force, for example of constant intensity. As a variant, however, the support is continuous but of variable intensity, for example chosen as a function of the local radius of curvature of the form to be cut and, for example, supplemented by a periodic intensity variation, that is to say a vibrant support. In another variant, the support on the glass sheet is made discontinuously. The local support means is moved relative to the glass sheet. Note however that alternatively, it is the glass sheet that is moved, or both. In general, this is a relative displacement of the local support means 20 with respect to the glass sheet 4. The flat bearing surface 8 is for example formed by a table, and therefore by a continuous flat surface. However, alternatively, the planar support surface 8 may not be continuous. It could be for example several flat supports obtained for example by pieces of tables. What is important 25 is that, in relation to the local support 10, a plan support 8 be provided, that is, support at least twice as wide as the support provided by the support means. local, in order to get a clean break. Also note that the flipping step is optional. It is possible, for example, to use a suction table to lift the glass sheet 4 and thus press the local support means 10 from below, the first face 4A of the glass sheet being then against the suction table. This is explained in more detail below. Figures 7a-7c, 8a-8c, 9a-9c and 10a-10c schematically illustrate four different types of machines for carrying out the method. The machine of Figures 7a-7c uses a suction table 12. A sheet of glass 4 is conveyed to a cutting table 14 (Figure 7a). A standard cutting machine 16 can then be used to make a cutting line 2 along the contour of the complex shape to obtain. The suction table 12 is for example brought above the cutting table 14, as shown in Figure 7b, so as to suck the glass sheet 4 by its first face 4A.
    [0010] In a third step (FIG. 7c), the local support means 10 is brought against the opposite face 4B of the glass sheet 4, facing the cutting line 2. The suction table 12 can also be configured so as to that the falls fall by gravity while the one or more complex shapes that have been cut remain sucked by the suction table 12 and are conveyed by it further, as shown in the right-hand diagram of FIG. 7c. However, it is understood that this is a simple example of a machine and that it is possible to envisage variants of any suitable type. The machine has at least one computer and a memory on which machine control programs are stored. The programs are able to control the machine of Figures 7a-7c, more particularly to control the cutting tool 6, the suction table 12 and the local support means 8. It is the same for the other machines of Figures 8a -8c, 9a-9c and 10a-10c. The machine of Figures 7a-7c has the advantage of not requiring transfer of the glass sheet 4 on a conveyor before breaking, and thus avoid a geometric registration to know the position of the cutting line 2, likewise than a gain of space. Figures 8a-8c illustrate a machine comprising a conveyor 18 for transferring the glass sheet from its cutting site to its breaking point. The cutting step of Figure 8a is similar to that of Figure 7a. Figure 8b illustrates the transfer by the conveyor 18 to the breaking point. Figure 8c illustrates the breaking step. To prevent a reversal of the glass sheet 4, a flat bearing surface 8 is applied against the first face 4A. The opposite face 4B against which the local support means 10 is supported is in turn cantilevered so that the area corresponding to the cutting line 2 is clear of the support table 20 carrying the glass sheet 4 by its so-called opposite side 4B. Alternatively, it is of course possible to provide a reversal of the glass sheet 4 as explained above with respect to the method. However, a machine according to FIG. 8c also makes it easier to choose and adapt the rigidity and hardness of the plane bearing material 8. FIGS. 9a-9c illustrate a variant of the example of FIGS. 8a-8c, FIG. variant in which the breaking is performed through a flexible conveyor belt 22 of the glass sheet. It should be noted that the local support means 10 need not necessarily be in direct contact with the glass. Note also that alternatively Figures 8a-8c and 9a-9c, the transfer can be performed by a suction table 24. This is also illustrated in Figure 10a. But the machine of Figures 10a-10c also differs from the previous ones for other reasons. The main difference is that the glass sheet is rotated during the breaking step, while remaining in its plane, as shown in Figure 10b. It is a rotation around a perpendicular to the general plane of the glass sheet. Furthermore, in FIG. 10b, the support plate 26 of the glass sheet 4 is sufficiently flexible so that the local support means 10 can press on the opposite face 4B through the support plate 26 and thus break the complex glass sheet following the contour of the complex shape. A planar support means 8 is pressed against the first face 4A of the glass sheet, in a manner similar to FIG. 8c.
    [0011] The local support means 10 is, for example, mounted in two dimensions only, thanks to the rotation of the glass sheet 4. FIG. 10c illustrates the separation of the complex shape by means of a suction table 28. In a variant it is another means of any suitable type. 3024 136 - 12 The following description aims to explain the advantages of the invention on the configuration possibilities of the production line. Beforehand, it is worth recalling the following. The cut-outs of complex-shaped glazings, ie for example motor vehicle glazings, are generally made in two stages from a "large format" glass sheet, also called "PLF" for "Large Shelf Plate" or DLF. . It is glass sheets of which at least one dimension corresponds to the width of the float glass ribbon from which they are derived. The "PLFs" are obtained directly by transverse cutting in the float glass ribbon. The width of the PLFs corresponds to the width of the float glass ribbon. Their length corresponds to the length of cut ribbon. DLFs are smaller glass sheets, the length of which corresponds to the width of the float glass ribbon. The DLFs are obtained either directly by cutting in the float glass ribbon but with a cut ribbon length smaller than the width of the float glass ribbon, or else by cutting the PLF transversely to its length. Thus, in practice, PLFs have minimum dimensions of at least 2.9m by at least 4.7m and DLFs of dimensions of at least 2.9m by at least 1.3m.
    [0012] In order to manufacture a complex shaped glazing, subsequent cutting steps are necessary. PLF or DLF are generally cut first of rectangular or trapezoidal glass sheets 30, called "primitives". These are sheets of glass whose shape is a polygon containing the final glazing of complex shape 32 to be made while leaving all the way round a "trim" 34 sufficient to proceed with the break. This is illustrated in FIG. 11. In a second step, a second cutting station is used to shape the glazing to be shaped, that is to say to cut the "trimmers" 34 all around the primitive 30 so that the edges of the glazing 32 are now ready to shape. For this, several cutting lines are for example made as illustrated in Figures 2a-2d for an example of square primitive. Shaping consisting of grinding is then performed later. 3024 136 - 13 The cutting of the primitives 30 in the PLF or DLF is thus performed on a first cutting station while shaping of the ready-to-shape glazing 34 is performed on a second cutting station. At each cutting station one proceeds: - to trace cutting lines; and at break along the cutting lines. Figs. 12a-12b illustrate cutout design examples in which the dashed lines represent the form to be cut ready to shape while the dotted lines represent the cutting lines made on the first cutting station. As illustrated by FIGS. 12a-12b, an advantage of the invention is that it makes it possible to make cuts of at least some edges of complex shape on the first cutting station, ie on the cutting station of the primitive 30. Cut out edges ready to shape on the first cutting station can reduce falls, avoiding to provide "trimmers" on these edges. In the case of Figure 12a, some edges 36 of complex shape only are cut in their complex shape while other edges 38 will be only in the second cutting step on the second cutting station.
    [0013] In the example of FIG. 12b, the shape cutout ready to shape the entire contour of the glazing is made on the first cutting station (the entire contour is in dashed lines 36). Figures 13a-13b illustrate another advantage of the invention, namely to allow to nest complex shapes to cut. Such a configuration will also reduce falls, as can be seen from Figs. 13a and 13b. In addition, the cut according to the form ready to shape can, as explained above for Figures 12a and 12b, start from the first cutting step on the first cutting station. In Figure 13a, two of the edges 36 are cut on the first cutting station, said "primitive" cutting station, even if it is no longer primitive in the strict sense. In FIG. 13b, the shape cut-out ready to shape over the entire contour of the glazing unit is made entirely on the first cutting station, without the passage of the "primitive" cutting step, in a manner similar to FIG. 12b.
