Definitions
- the present invention relates to the field of cutting pieces of glass in glass sheets of large dimensions.
- the glass is generally manufactured in the form of a continuous ribbon, for example a continuous ribbon of float glass or cast glass.
- This ribbon is then cut into sheets of glass called “motherglass” (literally “mother glass” in French even if this term is not used); which sheets are for example "PLF” (Large Format Glass Trays), typically of dimensions 3.21 m by about 6m or “DLF” of dimensions approximately 2.55m by 3.21m.
- PPF Large Format Glass Trays
- a defect analysis step is performed prior to this cutting to check whether the glass ribbon corresponds to defect specifications. If there are out-of-specification defaults, the motherglass is cut out by excluding a certain length of the ribbon corresponding to the off-specification portion of the ribbon.
- the defects are for example marked with an ink so as to identify them later without a new analysis.
- the motherglass can then be stacked in different piles according to the defect specification classes.
- the motherglass can then undergo one or more transformation processes (for example depositing a layer, laminating, ).
- the motherglass are for example analyzed for possible defaults and thus check whether the quality corresponds to a predetermined specification. Otherwise, the motherglass is rejected.

- an application glass such as a glass for automotive glazing, glazing for solar application, for example photovoltaic, glazing for OLED application, mirror or building glazing at a second manufacturer, client of the first.
- the first manufacturer produces in a plant 2 called "float glass", a continuous ribbon 4 of float glass on a bath of tin. Defects in the ribbon 4 are analyzed by a detection device 6 (of any suitable type), then the ribbon 2 cut into a motherglass 8.
- the detection device is for example a device called “scanner” in the industry and intended to analyze the glass to detect defects.
- Information concerning the defects relating to each motherglass is stored in a database 10.
- the defects are marked with an identifier 12, for example a barcode, an RFID chip or other means of any suitable type.

- the defects are not stored in this way, that is to say by registration in an electronic memory. They are for example marked by an ink on the defects of the glass, which ink will for example be read by a camera.
- the motherglass are, for example, then stacked 14 and stored 16 before being conveyed for a transformation process 18, for example for depositing a coating with a "coater", typically at least one conductive or dielectric coating, transparent or reflective , and having thicknesses of a few tens or hundreds of nanometers in thickness, or for example for a lamination process or a mirror formation.
- a transformation process for example for depositing a coating with a "coater”, typically at least one conductive or dielectric coating, transparent or reflective , and having thicknesses of a few tens or hundreds of nanometers in thickness, or for example for a lamination process or a mirror formation.
- the motherglass are for example analyzed by a second detection device 20, in particular for the purpose of detecting defects in the treatment or treatments performed.
- the detection device 20 is for example a "scanner" as mentioned above.
- the detection device 20 is able to identify the motherglass 8, for example by means of a barcode reader. It is furthermore for example connected to the database 10 so as to be able to use the stored fault information for each motherglass, for example for a more detailed inspection of the areas with known defects, and so as to be able to store the new information. of defects generated by the detection device 20 for each motherglass 8 analyzed.
- the detection device 20 comprises for example in addition to or in replacement of the "scanner", a camera detecting the position of the tasks at the entrance of the line of transformation.
- Database 10 is optional. It may be an alternative of a removable memory medium and read by the detection device 20 or a tool connected to the detection device 20.
- the motherglass 8 are again stacked 22 and stored 24, for example on the basis of the stored fault information, before being routed to a client.
- the customer is the one who will cut the motherglass into pieces of glass, typically several sheets of glass with identical dimensions. Note that alternatively, it is not a customer but the first manufacturer itself, for example an internal transformer.
- the customer has a calculator tool 28 in which stored programs are able to provide an optimum cutting plane for example on groups of several motherglass or on one, in order to minimize the amount of glass to be rejected.
- the customer has for example an identifier reader to identify each motherglass 8 and for example has access to the database 10, which is for example connected to the calculator tool 28 by an information system such as the Internet.
- the information is for example filtered by a filter 30, so that only the information useful to the customer is accessible or so that this information is accessible in a compatible format.
- the customer is, for example, equipped with a camera detecting the position and / or the color and / or the size of the tasks at the same time. input of the cutting line and transmitting this information to the computer 28.
- the motherglass are cut 32 according to the cutting planes that the computer 28 has selected for each motherglass 8.
- the cut pieces are for example washed 34 before being optionally analyzed by a third detection device 36 and then for example assembled in a multiple glazing building or automotive glazing.
- thermoplastic interlayer for example PVB type.
- the invention relates more particularly to the dynamic generation of an optimum cutting plane.
- a first aspect of the invention it is in effect to generate dynamically an optimum cutting plane for each of the glass sheets according to the information relating to the defects that have been stored, the optimum being obtained by a iterative and automatic calculation, for example by a linear optimization.
- FIG. 2 illustrates an example of a motherglass for which various defects have been listed, namely, a pinhole-type defect 36 on the coating, a bubble-type defect 38, a 40 scratch type defect on the glass, and a defect 42 type surface defect.
- the dynamic generation is, in this example, carried out by a linear optimization, that is to say by the iterative resolution of a problem of optimization of a linear function on a convex polyhedron representing constraints on the variables, the constraints being linear equations.
- a linear optimization that is to say by the iterative resolution of a problem of optimization of a linear function on a convex polyhedron representing constraints on the variables, the constraints being linear equations.
- it is a dynamic calculation optimization program of any suitable type.
- the advantage of linear programming is its speed of calculation.
- the program calculates only one cutting plane, which is known to be optimum.
- the objective chosen is to minimize a function representative of the number of primitives including at least one defect.
- the function provides a value representative of the number of cut glass pieces in the generated cutting plane and / or a sum of one or more dimensions of the cut glass pieces such as the total area of the cut glass pieces. and / or a sum of the cost of cut pieces of glass.
- the pieces to be cut also called “primitives” in the industry, are rectangles (see Figure 3).
- the image is for example pixelated and a polygon, whether it is a rectangle, a parallelogram or other, is then a combination of pixels.
- rectangles For each primitive, here being rectangles, two variables and two parameters are used here to define its position relative to the motherglass. Indeed, the rectangles have in this example always the same orientation, that is to say, an orientation with the length parallel to the length of the motherglass.
- the coordinates of abscissae x m and ordinates , for example, of the lower left corner of each primitive i are for example, chosen as variables to represent the position of each rectangle.
- the variables indicate an angle of the primitive with respect to a reference, so as to be able to move the primitive in rotation during the optimization.
- the two parameters (constant by definition) chosen here are the length and the width of the rectangle, which make it possible to calculate, from the coordinates of the lower left corner of the piece to be cut, the ordinate from the upper left corner and the abscissa from the bottom right corner.
- these are parameters of any type adapted to indicate the dimensions or the orientation of the primitive.
- intersection constraint of two primitives is introduced.
- the constraint "Intersection (i, j)" of two primitives is equal to 1 if two primitives overlap and 0 otherwise. This constraint must of course be equal to 0.
- n is an integer corresponding to the number of primitives that one wishes to be able to cut into the sheet.
- IntersectionQ actually contains 4 constraints, namely
- the value of the function is calculated by creating a matrix of n rows and m columns, where m is an integer corresponding to the number of defects.
- Each defect is defined by a rectangle whose positioning is defined for example in the same way as the primitives, namely with ⁇ ,, ⁇ , Xj.fin and yn. In the same way as for primitives, it is more generally a closed figure of any suitable type, for example a polygon.
- a function Fault (i, j) 1 in case of intersection of the primitive rectangle i with the default rectangle j and equal to 0 otherwise by checking at least one of the four inequalities mentioned above for the constraint IntersectionQ.
- Default (i, j) is not a constraint but a value used to calculate the objective function to maximize.
- the calculator then calculates Default (i, j) for each primitive i.
- the iterations are performed from this initial cutting plane, for which the function to be optimized is calculated during a first initialization step.
- linear programming is only one of many possibilities to generate an optimal cutting plan by a dynamic calculation, as well as the way to pose the problem to be solved and to solve it.
- the function may not be linear, as well as the equations induced by the constraints.
- Another possibility to extend the example above is to consider primitives of different sizes and / or with different orientations.
- One way of doing, for primitives rectangles, is to consider as variables, besides the coordinates ( ⁇ ,, ⁇ , yuni) of the lower left corner, the length and the width to determine the size, and an angle of orientation of the rectangle to determine the orientation.
- Compliance with the specifications is, for example, integrated into the objective function or considered as a constraint.
- the optimization can be performed for several fault acceptance criteria.
- the types of defects and the acceptance of these defects for each type of primitive are then for example parameters taken into account by the program.
- the default calculation (i, j) then takes these parameters into account.
- the value of Fault (i, j) will for example be equal to 0 if it intersects with defects of an acceptable type for the primitive considered.
- the acceptance criteria are for example different for different pieces of glass to be cut and / or different motherglass.
- FIG. 4 illustrates an example of an optimum cutting plan in which the defects 36 and 38 are considered acceptable for the pieces of glass concerned, while the defects 40 and 42 are not acceptable for any of the pieces to be cut.
- the primitives are divided into different zones corresponding to different criteria for acceptance of the defects, so as to provide an optimum cutting plane according to different fault acceptance criteria for different areas of the pieces to be cut.
- the various areas of acceptance of the defects are, for example, rectangles included in each other inside the piece to be cut.
- each zone inside the primitive (z1 and z2 in FIG. 4) is for example defined by four parameters, namely for example the relative coordinates of its lower left corner relative to the lower left corner of the primitive, its length and width.
- zone z2 inside zone z1.
- the number of zones in a primitive is for example an additional parameter of the primitive.
- the "Fault" function described above can be adapted as follows.
- Criteria for accepting defects for the different zones are for example defined as additional parameters of each zone.
- the defects are for example assigned parameters such as their size or type (bubble, scratch %) to accept them differently in each zone. This is however necessary in the simplest case where each zone accepts either all the defects taken into account, or none.
- PositionFault (i, z1 j) 1 if intersection of the area rectangle z1 with the default rectangle j and equal to 0 otherwise by checking at least one of four inequalities similar to those mentioned above for the intersection of the primitives. This function checks for the presence of the fault in the zone.
- PositionFault (i, z1 j) 1
- the program then proceeds in the same manner as described above for calculating the objective function.
- DefaultType (i, z1, j) 1 if the type is not accepted for zone z1 and 0 otherwise, and
- the program then proceeds in the same manner as described above for calculating the objective function.
- the various aspects of the invention can be applied to many glassmaking processes.
- FIG. 1 can be generalized to manufacturing processes of any suitable type.
- the number of fault analysis steps is of any suitable type.
- An advantage of the identification of the motherglass 8 or the ink marking of the defects is to enable these different analyzes to be carried out independently, each detection device then being for example provided with one or more readers for identifying the motherglass and connected to the database 10.
- the identifier especially in the case of a marking of the identifier, it will advantageously be a marking on the edge of the motherglass, so as to easily read these once stacked.
- the customer is then able to identify the different types of defects, their size and their position and can, for example by automatic readers, for example cameras, generate itself defect information useful to the plan optimization program cutting.
- Another aspect of the method of Figure 1 relates to the location and timing of the optimization.
- the optimization of the cut is performed at the customer, that is to say in the one who cuts. Nevertheless, this optimization can of course be carried out at the motherglass manufacturer, insofar as the information concerning the pieces of glass to be cut and the criteria for accepting defects are known to him.
- This optimization at the manufacturer of motherglass will be all the more advantageous that it will allow him to perform cutting optimizations on more large numbers of motherglass for example by grouping the motherglass intended for different customers.
- the distribution of motherglass to different customers can be divided according to results of the optimization, avoiding in this way to send a customer a motherglass that will not be optimum while this motherglass would have been more optimal to cut at another customer.
- the motherglass manufacturer can of course also make a first cut of a motherglass for example to send a part to a first client and the other party to a second client, customers performing a second cut in these pieces.
