BACKGROUND OF THE INVENTION This plate or this panel may be of any porous construction material, for example based on fibers such as mineral wool or wool of bio-based materials or a wool comprising different types of fibers. The panel may also be a pressed mineral fiber panel or a panel based on bio-based materials, such as wood or other natural fibers, or based on polymer fibers, or based on a mixture of different types of fibers. etc.
    These porous building materials can be produced by in-line processes where a dry or liquid mixture is prepared, especially in air suspension of fibers, this mixture containing a binding agent, and the mixture is deposited or distributed on an organ. conveyor and subjected to setting operations or hardening of the binding agent. Finally a solid material is obtained which is cut to the desired dimensions to shape a final product, if necessary before subsequent processing steps. A first cut is made in line to separate individual elements, and one or more cutting operations can be performed in recovery workshops.
    In the online processes, there are cutting devices such as guillotine saws, band saws, circular saws, or cutters or routers. However, these cutting devices also have the disadvantage of generating a lot of dust, which is potentially dangerous for operators. In addition, these cutters generally have saw teeth shifted in the thickness, which can generate significant waste and waste material.
    There are also devices with high pressure water jets, which can certainly limit the dust but have the disadvantage of bringing a significant amount of water on the cutting surfaces, which can be absorbed by the porous material and penalize the properties including mechanical material at the expense of the quality of the final construction.

Other features and advantages of the invention will now be described with reference to the drawings, in which: FIG. 1 represents a front view of a cutting device according to the invention; • Figure 2 shows a side view in detail of the cutting device according to the invention; • Figure 3 shows a sectional view of an example of cutting in a plate or a panel, made with the device according to the invention.
    The reference numbers which are identical in the different figures represent similar or identical elements. The invention relates to a device for cutting a plate or a panel of porous construction material, comprising means for moving the plate or the panel, which comprise at least one conveyor, able to move according to a direction X, a wire adapted to cut the plate or panel, and means for scrolling the yarn in a direction Y perpendicular to the X direction of movement of the plate or panel.
    The wire makes it possible to limit as much as possible the losses of material and the waste generated because the wire is much thinner than the saws of the known cutting devices. In addition, wire cutting generates virtually no dust, which improves the working conditions of the operators.
    Particularly in the case of a rock wool product containing granules of fiber material, it has been observed that the particulate cutting residues are considerably reduced in number and mass, and that they contain much less grain than with a conventional cut, the grains remaining mainly included in the mineral product. It is assumed here that the cutting wire creates a path between the fibers, respectively between the fibers and the grains, and releases the fibers by separating the fibrous entanglement, rather than breaking the fibers. This can be achieved by choosing a sufficiently fine wire with respect to the defects of the fibrous product, typically of smaller diameter than the size of the unpaired particles which can be from 1 to several millimeters in diameter.
    The term "plate or panel" is either a continuous strip or an object of substantially parallelepiped shape, which generally results from cutting in line after curing of the binder, and which may even have been cut off offline later. The term "plate or panel" includes plates or panels adapted to be rolled for marketing.
    Figure 1 shows a front view of the cutting device according to the invention.
    The plate or panel 1 of porous construction material, intended to be cut on the device according to the invention, has for example a density greater than or equal to 5 kg / m3, in particular at least 10 kg / m3, especially at least 20 to 25 kg / m3 and preferably less than 180 kg / m3.
    The cutting device according to the invention comprises means for moving a plate or a panel 1 of porous construction material in a direction X, and a wire 2 adapted to cut the plate or the panel 1. The cutting device according to the invention also comprises means 8, 9 for scrolling the yarn 2 in a direction Y perpendicular to the direction X of displacement of the plate or the panel 1. Here, the means for scrolling 8, 9 of the yarn are coils. Alternatively, the wire can scroll in the Y direction by a back and forth motion or reciprocation.
    According to the embodiments, the wire may be fixed relative to the direction Z or able to move in this direction Z, the direction Z being perpendicular to both the X direction of movement of the plate or panel 1 and to y-direction of yarn 2 scrolling.
    The means for moving the plate or the panel 1 comprise at least one conveyor 3, 4. The conveyor 3, 4 is a horizontal belt conveyor on which the plate or the panel 1. The conveyor can move forward or backward depending on the cutting needs. The direction of displacement is the X axis in FIG. 1. The plate or the panel 1 can rest horizontally, placed flat, or vertically, placed on its edge, on the conveyor 3, 4.
    The conveyor 3, 4 is preferably in two parts when the wire 2 is able to move in the direction Z. Thus, a space is provided between the two conveyor parts 3, 4 to allow the passage of the wire 2 for cutting transverse of the plate or panel 1, without being impeded by the conveyor.
    When the plate or the panel 1 is in the form of horizontal continuous strip, the wire 2 can allow cutting in line, for example in two in the thickness. The wire 2 is then fixed and the plate or the panel rests horizontally on the conveyor.
    When the plate or panel 1 is in the form of horizontal continuous strip, the wire 2 may also allow a transverse cut in line, for example to form plates or panels of substantially parallelepiped shape. The wire 2 is then able to move in the Z direction.
    When the plate or panel 1 rests vertically on the conveyor 3, 4 horizontal, the wire 2 may be fixed relative to the Z axis or able to move in the Z direction.
    According to the embodiments, the cutting device according to the invention can therefore comprise means for moving the wire 2 in the direction Z, these displacement means allowing a displacement of the wire 2 in a direction Z perpendicular to both the direction X of displacement of the plate or panel 1 and the Y direction of travel of the wire 2. Thus, the device allows for cuts in two directions perpendicular to each other. In this way, several different cuts can be made in one pass. Moreover, by combining the two movement movements in the X and Z directions, it is possible to make cuts of various shapes.
    Furthermore, when the plate or the panel 1 rests vertically on the horizontal conveyor, the device comprises gripping means 5, 6, 7 of the plate or the panel 1 in order to maintain the plate or the panel in position. In this case, the gripping means 5, 6, 7 of the plate or panel 1 are able to move simultaneously and in the same direction X as the conveyor 3, 4 for uniform movement of the plate or panel 1.
    The gripping means of the plate or panel 1 comprises a vacuum gripping system 5, 6, 7. The vacuum gripping system 5, 6, 7 consists of grippers 5, 6 under vacuum fixed on a movable support 7 adapted at the same time as the conveyor or conveyors 3, 4 during the cutting of the plate or the panel 1. The vacuum grippers 5, 6 may be in the form of plates pierced with a multitude of orifices connected to a means depressurization; the diameter of the orifices are chosen according to the force that it is desired to apply locally on the plate or the panel 1. The grippers 5, 6 may have different sizes, as shown in FIG. 1. The plate or the panel 1 must be perfectly held by vacuum grippers 5, 6 during cutting by the wire 2 to allow cutting as accurate as possible. Larger grippers allow better maintenance of small plates or panels. The vacuum grippers 5, 6 must be able to hold the plate 1 without constraining it, without deforming it. These vacuum grippers take up the forces exerted by the wire during the displacement of the plate or panel 1 and / or wire 2 to ensure perfect control of the dynamic positioning of the plate or panel, and avoiding any slippage of the plate or of the panel relative to the gripper. The synchronization of the different movements is ensured by a numerical control system. In Figure 1, only the vacuum grippers 5 maintain the plate or panel 1 because in this embodiment the plate or panel is reduced in size. Vacuum grippers 6, peripherals, are used in addition to the vacuum grippers 5 for plates or panels 1 of larger size.
    The wire 2 is preferably a steel wire with a diameter of between 300 μm and 2 mm, in particular between 400 μm and less than 1 mm, in particular between 400 μm and 700 μm, preferably between 420 μm and 550 μm to improve the cutting quality, even between 480 pm and 520 pm to further improve the quality of the cut. The steel wire may comprise on its surface abrasive particles, which are for example diamond, zirconium oxide or boron nitride. The size of the abrasive particles is preferably between 30 and 80 μm. The space between the abrasive particles is preferably between 10 μm and 20 μm. The presence of abrasive particles makes it possible to make a clean cut, which makes it possible to overcome a subsequent sanding.
    According to one embodiment of the invention, the wire 2 is fixed at each of its ends to a coil 8, 9. The wire 2 is wound on the two coils 8, 9, the space between the two coils 8, 9 being greater than at least one dimension of the plate or panel 1 to be cut. The yarn 2 is preferably vertical (along the Y axis), as shown in FIGS. 1 and 2. Each of the lower 8 and upper 9 coils is rotated by a motor (not shown). The coils 8, 9 are slaved to each other by a servo system to maintain a constant wire tension and to control the speed of travel of the wire 2. This servo system is described in more detail later in the text. The wire 2 has a length for example between 5 and 15 km. It unwinds from one reel to wind on the other reel. When one reel 8, 9 is empty and the other is full, the direction of travel of the yarn 2 is reversed so that the yarn winds on the empty reel and unwinds from the full reel.
    Figure 2 shows a side view in detail of the cutting device according to the invention.
    The wire 2 is guided, at the exit of each of the coils 8, 9, by a guide pulley 10, 11 respectively, which ensures the positioning of the wire 2 relative to the plate or panel 1 to be cut. At the exit of each of the guide pulleys 10, 11, the wire is further guided by a roller 12, 13 respectively, which makes it possible to position the wire even more precisely. Thus, when the wire 2 is in the vertical position (along the Y axis), as in FIGS. 1 and 2, the wire 2 passes for example through the lower coil 8 then through the lower guide pulley 10 and then by the roller 12 lower then by the upper roller 13 and then by the upper guide pulley 11 and the upper coil 9. When cutting by the wire 2, the plate 1 passes between the two rollers 12, 13.
    The linear speed of travel of the wire 2 is between 10 m / s and 20 m / s, preferably between 14 m / s and 16 m / s, or even equal to 15 m / s, to further improve the quality of the cutting. The wire 2 scrolls dry, without passage in a coolant.
    The tension of the yarn 2 is between 150 N and 500 N, preferably between 250 N and 350 N to further improve the quality of the cut. The tension of the diamond wire depends on the diameter of the wire. The more the wire is stretched, the more its flexion is reduced. As the wire 2 can be subjected to very high stresses, it is preferably made of steel with a very high elastic limit that can withstand stresses up to 1000 MPa, or even 2000 MPa.
    The diameter, the linear speed and the tension of the yarn 2 are three very important parameters for a clean cut of the plate. Also, the cutting device according to the invention comprises several sensors connected to the servo system, which allow the servo system to adapt in real time (every 5 ms) the speed of rotation of the coils 8, 9 to maintain constant linear velocity and tension during cutting.
    Thus, the cutting device comprises, in front of each coil 8, 9 an optical sensor 14, 15 respectively, which measures the diameter of the coil (or more precisely the outside diameter of the coil of wire on the coil): as As explained above, the diameter of the spool varies during cutting as the thread unwinds from one spool to wind on the other spool. This variation in diameter is taken into account in real time to adjust the winding / unwinding speed of the coils 8, 9 and to guarantee the desired linear speed. The data of these optical sensors 14, 15 also allow evaluation of the remaining wire length on each of the coils.
    The cutting device also comprises two positioning measuring sensors 16, 17 positioned respectively between the lower spool 8 and the lower guide pulley 10, and between the upper spool 9 and the upper guide pulley 11. These sensors 16 and 17 measure the position and the bending of the wire 2 along the axis X. Each of the coils 8, 9 is mounted on a worm, 80, 90 respectively, with an axis parallel to the direction X, to allow a real-time alignment between the position of the wire 2 winding / unwinding of the coils 8, 9 and the position of the guide pulleys 10, 11, along the axis X. The sensors 16, 17 make it possible to adjust this function of troncannage.
    The cutting device also comprises a bending measurement sensor 18 positioned between the rollers 12, 13. This flexion measuring sensor 18 makes it possible to measure the deformation of the wire along the X axis, imposed by the thrust made by the product in its relative displacement with respect to the wire. The data of this flexion measuring sensor 18, coupled to the data of the optical sensors 14, 15, make it possible to adjust the tension of the thread in real time by adjusting the winding / unwinding speed of the coils 8, 9. bending 18 thus allows to adjust the straightness of the wire.
    The positioning and bending measurement sensors 16 to 18 are, for example, digital strips provided with a plurality of laser beams which detect the trace of the wire.
    Thanks to these sensors 14 to 18, which are means of very precise control of the tension of the yarn, it is thus possible to minimize the vibration amplitude of the yarn, so that no more waves are perceptible by a visual examination of the yarn. cut face, which gives an almost perfect aesthetic. The tension of the yarn, adjusted to avoid vibrations, causes the yarn to behave more like a wedge that spreads a crack in the material than a knife that cuts the fibers in half.
    Finally, the assembly formed by the wire 2, the coils 8, 9, the guide pulleys 10, 11, the rollers 12, 13 and the sensors 14 to 18 is mounted on a frame or an upright (not shown), even associated with moving means (not shown). These displacement means allow a displacement of the wire 2 in the direction Z of FIG. 1, or along an axis perpendicular to both the direction of movement of the plate or the panel 1, which is along the axis X, and to Y direction of yarn 2. The two movement movements along the X and Z axes can be combined to make cuts of complex shape. The speed of movement of the wire 2 along the Z axis is between 10 mm / s and 2 m / s, in particular between 10 mm / s and 250 mm / s for cutting at the edges in order to allow precision of the geometric pattern edges.
    The cutting device according to the invention makes it possible to cut a plate or a panel 1: in its width or length in order to obtain a plate or panel of smaller size, in its thickness in order to obtain at least two plates or panels of a thickness less than that of the plate or of the starting panel, and / or - on its edges in order to make a rabbet or any other form of edge detail.
    During cutting, the speed of movement of the plate or panel 1 is between 500 mm / s and 2 m / s for cutting in the thickness of the slitting type and between 10 mm / s and 2 m / s, in particular between 10 mm / s and 250 mm / s for cutting on the edges to allow a precision of the geometric pattern of the edges. The plate or the panel 1 moves by joint movement of the conveyors 3, 4 and the vacuum gripping system 5, 6, 7.
    The rabbets or edge cutouts can have any imaginable shape, with geometries as varied as square, rectangles, triangles, polygonal, rounded, curvilinear, sinusoidal, etc ...
    Movement movements of the plate or panel, movements of wire movement, winding / unwinding speeds of reels, worm movements and actuation of vacuum grippers are motorized and controlled by a system. general control of the device.
    The cutting device according to the invention allows for example acoustic panels mineral wool ceiling. The rabbets of such acoustic panels, made on each of its edges, are intended to rest on a metal frame fixed to the ceiling. Such panels are generally square in shape but can also be rectangular. When the plate or panel is cut in two in thickness from a veneered board or panel on both its main faces, the resulting panel usually has a veil on only one of its main faces . A veil can then be glued to the other main face of the panel from the cut.
    The cutting device according to the invention allows for example to cut a plate or a panel at a time in its thickness, transversely in its width, and on its edges to make rabbets or any other edge detail, as shown in FIG. 3 for example.
    3 shows a sectional view of an example of cutting in a plate or a panel, made with the device according to the invention, along a path defined by the succession of sections marked by the capital letters.
    Thus, the plate or the panel can be cut on one of its edges to make a rabbet (mark T), then in two in its thickness (mark A), then transversely in its width with simultaneous cutting of rabbets (marks B, C, D, E), then cut in half again in the thickness (mark F), and so on so as to form several plates or panels with grooves cut on two opposite edges. Each plate or panel obtained is then rotated 90 ° to make a transverse cut in the direction of the initial length with simultaneous cutting rabbets on the two remaining edges. The rotation of 90 ° can be carried out by means of a vacuum gripper system similar to the grippers 5, 6 arranged opposite the grippers 5, 6. Alternatively, the cut panels can be conveyed to another cutting station equipped with another wire arranged to perform the rabbet cutting on the remaining edges.
    It is also possible to first cut the plate or panel to the correct size and then cut the rabbets.
    We then obtain one or more plates or panels, for example square or rectangular, with rabbets on each of their edges. The invention also relates to a cutting method implementing the cutting device according to the invention.
    Thus, the method of cutting plate or panel of porous construction material comprises the following steps: - supply of a plate or a panel 1 of porous construction material, - displacement of the plate or panel 1 in one direction X by displacement means 3, 4 which comprise at least one conveyor, - cutting of the plate or panel by a wire 2 capable of scrolling in a direction Y perpendicular to the X direction of movement of the plate or panel 1.
    During cutting, the plate or the panel 1 moves through the conveyor 3, 4. It can be held thanks to the vacuum gripping system 5, 6, 7. The wire 2 can be adapted to move in a direction perpendicular to both at the X direction of movement of the plate or panel 1 and Y direction of the wire.
    The cutting process can be performed online, at the end of the production line of the plate or panel 1. In this case, the cutting device is installed in line, the speed of movement of the plate or panel 1 is at least 1 or 2 m / min, preferably at least 15 m / min, or even at least 30 m / min, the cutting can be performed in the thickness or on the edges.
