Definitions
- the present invention relates to the production of structures needle-punched textiles for use in the manufacture of parts protection used at high temperatures, structural parts engines - rockets or very high-speed brake discs performance for aviation or land vehicles.
- the discs To resist these shear forces generating a delamination effect, the discs must be manufactured in such a way as to minimize structural heterogeneities. Indeed, a non uniform has local areas of stress with characteristics heterogeneous substances which considerably increase the risks of tear.
- brake discs are developed from a reinforcing textile structure, formed of a plurality of layers superimposed and needled by a set of barbed needles penetrating in the z direction, ie transversally to the layers.
- the textile structure After cutting, the textile structure is carbonized, densified to using a material forming a matrix and is eventually subject to to a heat treatment.
- the layers are superimposed on a support.
- a downward movement in steps is generally imposed on the support as the layering and needling of different layers. The mechanical characteristics of the final product thus obtained heavily dependent on the actual needling density selected for the reinforcement textile structure.
- the patent application EP 0 695 823 sought to improve the knowledge of the penetration depth of the needles by means of feeler rolls measuring the position of the upper surface of the textile structure between needling operations and arranged laterally to the working area of the needles.
- the present invention therefore proposes a needling machine and its associated method which overcomes this disadvantage by allowing a measurement of the actual penetration of the needles into the textile structure at needling taking into account its deformation during operations needling of the different layers that compose it.
- a needling machine of a textile structure formed of a plurality of superposed layers comprising a vertically movable needling table, a head needling device having a determined number of barbed needles and disposed vertically above said needling table, and means drive the needling head to give it a movement vertical alternative defining a low point of maximum penetration of needles in said textile structure, characterized in that it comprises in addition measuring means arranged at said head needling device for measuring the position of an upper surface of said textile structure at said low point of maximum penetration of the needles.
- these measuring means are arranged in a median plane of said needling head perpendicular to a direction in advance of said textile structure.
- these means of measuring the position of the upper surface of said textile structure comprise an optical measuring assembly without contact.
- it is a laser transmitter / receiver of the wide beam type.
- these measurement means may comprise a mechanical touch probe.
- a sensor is provided, preferably inductive or optical type, for determining said low point of penetration maximum needles and processing means to control the vertical displacement of said needling table according to the measuring the position of the upper surface of the textile structure performed at the said point of maximum penetration of the needles by the said measuring means.
- the invention also relates to the method used in the aforementioned machine and the textile structure obtained by this method.
- the measurement of the position of the upper surface of the textile structure is carried out by means of instantaneous measurements recorded in real time along the entire length of the textile structure.
- FIGS. 2 Two examples of realization of a machine allowing needling of a flat textile structure are shown in FIGS. 2.
- the invention is not limited to only the manufacture of flat structures and that of forming a structure by winding a fibrous web also finds application with the present invention, whether it is an annular winding of a tablecloth or helical fabric in coils superimposed flat, or a winding a sheet in turns superimposed on a mandrel.
- the machine conventionally comprises a so-called table 10 needling for supporting layers 12 or webs of width and length determined according to the final structure to be achieved, and will be brought one after the other to be superimposed in layers successive.
- the table is placed in line with a needling head 14 comprising, mounted on a needle board 16, a predetermined number barb needles 18 of known type, and which can be animated by a vertical reciprocating motion by one or more crank-handle assemblies 20 motorized by a single engine or not.
- a stripper 22 fixed on a frame 24 of the machine is mounted above the table needling to prevent the textile structure from being driven during the rise of needles.
- the table as the stripper are respectively pierced with holes 26, 28 for the passage of the needles.
- the table is vertically movable by means of a drive device 30 consisting for example of a motorized worm.
- a drive device 30 consisting for example of a motorized worm.
- Several series of drive rollers 32, 34 (also called input / output presses) arranged upstream and downstream of the machine provide transport horizontal of the textile structure towards the needling head.
- the stroke of the needles being constant with respect to the frame to which they are connected and the table needling being positioned at a known distance from this built, it is easy to show that the penetration distance of the needles in the textile material directly depends on the thickness of material existing between the needling table and the measured upper surface.
- the measuring means 36 are fixed on the frame 24 and it is expected that the needle board 16 (and the stripper 22) is pierced of an orifice 38 (respectively a through hole 40) to allow a cooperation of these measuring means with the upper surface of the textile structure.
- this cooperation may be done without contact (with a distance measurement of the position of the upper surface of the textile structure) or with contact (by the descent a mechanical probe on the upper surface of the textile structure).
- Figure 1 illustrates a preferred embodiment of the invention in which these contactless measuring means are constituted by an optical measuring unit such as a laser transmitter / receiver 42.
- the transmitter directs a laser beam, through the needle board, towards the upper surface of the structure textile (after having passed through the stripper) which then reflects it towards the receiver.
- the transmitter distance / needling table being assumed known by a prior measure, the determination of the distance emitter / upper surface of the textile structure, by path analysis back and forth of the laser beam, then is enough to accurately assess the thickness of the textile structure supported by the needling table.
- this laser assembly is preferably of the wide beam type (because this model laser by allowing measurements over the entire length of the beam ensures an integration effect).
- the use of a set optical infrared measurement is quite feasible without however, be privileged.
- FIG. 2 illustrates an alternative embodiment in which the measuring means consist of a mechanical probe formed an internal piston 44 fixed to the frame 24 and on which can slide a outer sleeve 46 whose slightly rounded end is intended for come into direct contact with the textile structure (after having crossed the needle board and stripper).
- This sliding of the sleeve is provided by the controlled injection of a fluid, preferably compressed air, in the piston from a control module 48 fixed 24.
- the fluid pressure is adjusted according to the nature of the textile structure to needling (hardness, rebound reaction) and adjusted way to avoid rebound of the sleeve on this textile structure.
- the sleeve also has at its upper part a collar reflector 50 intended to cooperate with an optical assembly of measured as a laser transmitter or infrared receiver 52 also fixed on the frame.
- the transmitter directs its radiation towards the collar of the sleeve which then reflects it to the receiver.
- the distance transceiver when the tip of the probe is in contact with the needling table, being assumed to be known by a prior measure, the determination of the transmitter / receiver distance when this end is in contact with the upper surface of the textile structure (by analysis the return path of the beam radiated) is again sufficient to evaluate precisely the thickness of the textile structure supported by the table needling.
- the means of measure 36 are preferably arranged in a median plane of the head needling 14 perpendicular to a direction of advance of the structure textile (it is of course not forbidden to deviate significantly). They can be split, when this textile structure is presented under the form of two adjacent plates advancing parallel to each other under the needling head.
- the needling head may comprise two needle boards independent devices arranged side by side, the measuring means then being placed substantially in the center of each of these boards.
- this figure 3 shows the machine, in the frame of the previous alternative embodiment, in two positions distinct, one (left part of this figure 3) corresponding to a resting position, the needling head being in the raised position, and the other (right part) corresponding to a position of this head at a low point of maximum needle penetration.
- the determination of the lowest point of maximum penetration of needles is performed in real time by a sensor 54, for example from inductive or optical type, integral with the frame and cooperating for example with a determined cam profile 56 of the crank-rod assembly 20 of vertical reciprocating movement of the needling head.
- This cam profile allows you to define a period of time (and not only a moment of unique and instantaneous measurement) during the descent of the needle board, preferably in the vicinity of the low point, during which the measuring means 36 will be active and can make the acquisition of several measures from which will be determined, at level of a processing module 58 connected on the one hand to the sensor 54 and on the other hand to the measuring means 36, a first average value of the thickness of the needled layers.
- the needling process implemented in the machine of the invention can be summarized as follows. First, superimpose a second layer thickness on a first layer thickness placed on the needling table and bind by barbed needles of a needling head, and according to predetermined conditions, the thicknesses of the two layers thus superimposed, then relatively move the table needling with respect to the needling head of a displacement step determined function of the position of a top surface of the two superimposed layers measured at a low point of maximum penetration needles by appropriate measuring means, and finally superimpose a third layer thickness on the previous two and bind this third layer thickness on the previous two according to the same predetermined conditions. These steps will then be repeated for following layers until the desired thickness for the structure textile.
- the process used in the machines described above consists in placing on the table 10 first or even two layers superimposed which are then bound by needling by means of the board with needles 16 while being moved horizontally over the entire length of the textile structure by advance rollers 32, 34.
- the table then descended from a determined displacement step to be able to superimpose a third layer which is in turn needled with the two more and so on until you get the desired thickness.
- this determined displacement step is not fixed or subject to a predefined descent law, but it results from the actual penetration of the needles into the layers of the textile structure measured at the low point of penetration maximum needles to obtain the actual needling density desired for this textile structure, constant or progressive density in the thickness of the textile structure. So, we measure in the center of the needles the position of the upper surface of this textile structure to handle the no descent of the needling table, so that these needles penetrate into the textile structure of a given distance.
