Definitions
- the present invention relates to a method of generating a sequence of cutting planes of a sequence of pieces of glass in a sequence of glass sheets.
- the invention also relates to a device for generating a sequence of cutting planes for implementing such a method.
- Flat glass is generally produced continuously in the form of a ribbon in which finely sized trays or sheets of glass, usually of large size generally not exceeding 9m x 4m, are cut.
- "Jumbo" glass sheets (6m x 3.21m) are examples of glass sheets that can be cut into the ribbon.
- a cutting plane can be considered as a tiling of the glass sheet by geometric shapes, generally rectangular and of different sizes, representing the pieces to be cut, and arranged in such a way as to reduce the total area of the falls. that is, the unworkable surface at the cut.
- the glass sheets in which the pieces are cut may also have defects. These defects must be excluded from the parts to be cut. It is then necessary to adapt the cutting plane so that the defects are located in the falls.
- US2005023337 A1 discloses a method of cutting glass pieces from a continuously produced glass ribbon. To be implemented, this method presupposes the preliminary knowledge of the pieces to be cut before cutting so that the cutting plane is continuously adapted according to the location of the defects detected on the glass ribbon. This method only makes it possible to cut pieces according to cutting planes corresponding to tilings of pieces in the same direction with a limited number of choice of cutting lines. It generates many falls. In addition, it is not applicable to the cutting of pieces of glass in glass sheets. In most installations, the glass sheets are stored, often stacked, before being subsequently cut from a transformer and / or at the appropriate time to the order of a customer.
- the manufacturer of the glass sheets does not have the prior knowledge of the parts to be cut or the tolerance with which the possible defects of the glass sheet may be taken into account by the transformer.
- the pieces of glass are cut a posteriori in a batch comprising a certain sequence of glass sheets to which the cutting plane or planes of said pieces must be adapted to take into account the defects they contain.
- the document WO 2014128424 A1 discloses a cutting method in which the cutting plane of each sheet is adapted, on the fly, at the moment when the glass sheet is depilated.
- the nature and location of the defects it contains are known only at the moment of unstacking.
- the cutting plane is optimized using an algorithm that explores the space of possible permutations of the pieces to be cut so as to place the defects in the falls. When this is not possible, the defects are placed in the smallest parts or areas of the parts to be masked during assembly.
- the present invention solves these problems. It relates to a method for generating a sequence of cutting planes of a P-sequence of glass pieces in a sequence F of glass sheets, said glass pieces being intended to be stacked according to order constraints and / or positioning on one or more trestles C 3 ⁇ 4 , said method comprising the following steps:
- the advantage of the process of the invention is that it anticipates the presence of defects possibly present in the glass sheets by taking them into consideration as soon as the cutting planes are generated and not subsequently.
- the method of the invention saves time and reduce glass losses at the time of cutting. It makes it possible to generate a single sequence of cutting planes for the cutting of the entire sequence of the parts and therefore avoids the modification of the cutting planes during unstacking of the glass sheets to take into account the defects that they can present. This results in an increase in production yields with elimination of almost all defects.
- the order and / or positioning constraints are chosen from the orientation of the pieces of glass in each bridge C k and / or the order of the pieces of glass in each bridge C k .
- the constraints of order and / or positioning of the pieces of glass for each easel are generally defined by the customer specifications to which the cut pieces are intended.
- the parts can be ordered and positioned according to the characteristics of the processes used by the customers for their possible transformation or assembly. The advantage for the customers is a reduction of the handling steps of the parts, and thus of the risks of breakage related to this manipulation.
- some parts can be placed in portrait mode and others in landscape mode in a certain order.
- the optimization criterion O can then be chosen so as to select the one that contributes to the reduction of the largest glass losses.
- the optimization criterion O is chosen from a minimum total area of loss criteria or a minimum number of cut sheet glass criteria.
- the generation of the sequence S i of cutting planes PDi j leaves can also be performed according to the cutting constraints of the glass pieces for each bridge C k .
- the cut can be a guillotine cut.
- the cutting planes may comprise several hierarchical levels of cutting. These hierarchical levels correspond to the orders and directions according to which the cuts are made according to the type of cut used.
- the guillotine cut-out generally passes right through the entire sheet of glass parallel to one of its edges. The order and orientation in which the pieces are cut in a cutting plane must make it possible to use such a cutting mode while minimizing the falls.
- the defects that may possibly comprise the glass sheets are generally of different types and sizes. Depending on the intended applications for each of the glass pieces, certain defects may be tolerated in said rooms.
- the generation of the sequence S i of cutting planes PD i of the glass sheets is carried out so that pieces of glass to be cut include defects satisfying a criterion of severity Y previously defined.
- the criterion of severity Y can be defined according to the final application aimed for the pieces of glass. This criterion can then correspond to set threshold values for one or more characteristics of the defects, and below which these defects have little effect for this application. For example, the same defect having a given size may be tolerated for use of the glass pieces as glazing of a building and not for a use as glazing of a vehicle.
- the severity criterion is therefore generally defined on the basis of the customer specifications for which the parts are intended.
- the criterion of severity Y is chosen from a criterion of size of the defects, a criterion of density of the defects on the glass sheet, a criterion of nature of the defects or a criterion of optical deterioration, alone or in combination.
- the pieces of glass are free of any defects.
- the generation of the sequence (s) S i of cutting planes PD ⁇ j of the glass sheets is carried out so that all the defects are placed in the glass falls, outside the chopping pieces.
- Steps (c) and (d) of the method of the invention are implemented by computer.
- the invention also relates to a computer program comprising instructions for carrying out the steps of the method of generating a sequence of cutting planes according to the invention in all possible embodiments.
- the steps of the method can be implemented using any type of programming language compiled into a binary form or directly interpreted in the form of computer-executable arithmetic or logic instructions or any programmable information processing system.
- the computer program may be part of a software package, that is, a set of executable instructions and / or one or more datasets or databases.
- the instructions of the computer program can implement the method of the invention using several types of algorithm.
- the generation of the sequences S i of the cutting planes PD i of the step (c) and / or the selection of one of the sequences S i of the cutting planes PD i of the step (d) are carried out at using an exploratory dendrogram, a heuristic or metaheuristic search method, a Lagrangian linear dualisation optimization, or a dynamic programming.
- the time required for the generation of one or more sequences S j of cutting planes PD may be relatively long and not very compatible with the rates Manufacturing.
- it may be advantageous for the duration necessary for the execution of the step of generating the sequence (s) S i of the cutting planes PD i of the glass sheets does not exceed a predefined duration.
- Said duration may in particular be predefined to meet the constraints of a manufacturing schedule.

Examples of symbol forming a code readable by the slice are described in the document WO 2015/121548 A1.
