Description

Title of the invention: Distribution tool for covering module

Technical area

The present presentation relates to a distribution tool for covering module, as well as a covering module and a rope manufacturing installation comprising such a distribution tool.

Such a distribution tool allows to properly distribute the ribbons

intended for guiping a guiping rope. It is in particular particularly useful for manufacturing cords comprising several superimposed layers, for example composite cords intended to form springs, in the automotive field in particular.

Prior art

The automotive industry requires the manufacture of large springs and high stiffness for the suspension of road vehicles. Historically, these automotive springs are made of metal. However, in recent years, in particular in order to obtain significant mass gains, developments have been carried out to produce such springs in composite materials.

Such composite springs are thus produced from a composite rope, formed from a plurality of fibrous layers impregnated with resin, wound around one another, shaped and then solidified by polymerization of the resin. In certain processes, the fibers of the different layers pass through a resin bath after the winding of each new fibrous layer, which is very tedious and generates significant losses of resin.

To date, among the known prepreg processes, the layers can be wound one by one in a discontinuous process during which the same rope during manufacture will have to run in full in a wrapping device as many times as layers to be superimposed: such a process allows very good regularity of the winding and control of each layer at the cost of an extremely long cycle time. According to another method, the cord traverses during its manufacture, continuously and in a single pass, a plurality of covering modules winding each fibrous layer one after the other. Such a continuous process offers a much shorter cycle time but raises important problems of regularity of the windings and therefore, in the end, of quality and conformity of the final spring.

Indeed, due to the continuous nature of this process, the slightest winding defect of any layer cannot be detected and affects the winding of all the following layers. In particular, in the event of poor distribution of the ribbons forming each layer, there is the appearance of local deformations or even oscillations along the rope.

Such defects can appear in the case of poor distribution between several ribbons forming the same fibrous layer, leading to overlaps in certain places and voids in others, or between ribbons forming different neighboring layers, certain ribbons of a subsequent layer can for example hinder the correct deposition of the ribbons of the anterior layer.

There is therefore a real need for a distribution tool for module

covering making it possible to resolve, at least in part, the drawbacks inherent in known methods.

Statement of the invention

The present disclosure relates to a distribution tool for covering module, comprising a sleeve, intended to rotate integrally with the covering module, the sleeve comprising a peripheral surface, an axial passage, provided to allow the axial passage of a guiding rope, and at least one guide opening extending between the peripheral surface and the axial passage and provided for guiding a ribbon intended to guiper the guiding rope.

Thus, thanks to such a distribution tool, it is possible to guide the various ribbons intended to guide the guiper string so as to control their position at the time of their application on the guiper rope: this ensures distribution correct ribbons relative to each other, which results in a regular wrapping of the guiper string, minimizing overlapping of ribbons or the appearance of voids between the ribbons.

As a result, it is possible to ensure regularity and a high covering quality all along the rope, even when many ribbons are wound simultaneously. It is thus possible to easily and effectively guipate ropes having large diameters and / or a large number of superimposed layers. In particular, when several layers are

overlapping, it is possible to bring together the successive covering modules, or even to merge certain covering modules, so as to reduce

the overall size of the covering or rope-making installation.

Such a distribution tool thus makes it possible to manufacture ropes

highly technical complexes for very demanding applications such as the manufacture of composite springs for example. The very regularity of the strings made possible by such a distribution tool in particular ensures maximum mechanical strength and reduces the risk of failure, or even breakage, of the spring in operation.

In addition, thanks to such a distribution tool, it is also possible

to accelerate the scrolling of the rope while maintaining a regularity and a satisfactory covering quality: this then makes it possible to reduce the cycle time of the covering process. Thus, a uniform distribution of the ribbons is obtained on the circumference of the rope, continuously and whatever the speed of

production.

In some embodiments, the sleeve has several

guide openings provided in a single row around the peripheral surface. In other words, the guide openings in the same row are located at the same level in the axial direction. When the production of a given layer requires the juxtaposition of several ribbons, this makes it possible to control the distribution of these ribbons within this layer.

In general, it is preferable that each guide opening

guides a single ribbon. In some embodiments, a row of guide openings comprises between 3 and 12 guide openings. This is preferably the case for all the rows of sleeve guide openings.

In some embodiments, the guide openings of at least one row are distributed equitably around the axial passage. This is preferably the case for all rows of sleeve guide openings.

In some embodiments, the sleeve has, in the axial direction, several rows of at least one guide opening. This makes it possible to deposit several fibrous layers within the same covering module, thereby reducing the costs and the space requirement of the complete installation. These different layers can also constitute sub-layers of the same layer of greater thickness: in particular, depending on the ribbons used, it is possible that the demarcation between the successively deposited sub-layers of the same layer is no longer , or practically more, visible in the finished product.

In some embodiments, the sleeve has between 1 and 4

rows of guide openings.

In some embodiments, the rows of guide openings are equidistant from each other.

In some embodiments, at least one first row

guide openings includes a different number of guide openings than a second row of guide openings. This makes it possible to use different types of ribbons, of different sizes for example, or even to ensure a uniform deposit of the ribbons even when the diameter of the rope changes during manufacture.

In some embodiments, the number of guide openings is increasing by traversing the rows in the axial direction. By “ascending” is meant that the number of guide openings has increased strictly between the first row and the last row, the first row preferably being the most upstream row, and that no row has fewer openings. guide than the previous row; however, two successive rows may possibly have the same number of guide openings. This allows a significant growth in the diameter of the rope during manufacture, and therefore the deposition of a greater number of layers.

In certain embodiments, the guide openings of at least one row are offset circumferentially relative to the guide openings of the immediately preceding row and / or of the row

immediately following. This is preferably the case for all rows of sleeve guide openings. This makes it possible to offset the overlapping area of the ribbons within a given layer with respect to the overlapping area of the ribbons in a neighboring layer, which improves the regularity of the wrapping, layer after layer.

In some embodiments, at least one guide opening, and preferably each guide opening, is axially inclined. This inclination is preferably identical for all the guide openings in the same row. It can also be the same or different between the rows. For example, this inclination can be between 10 ° and 80 °, preferably between 35 ° and 55 °.

In some embodiments, at least one guide opening, and preferably each guide opening, is tilted tangentially. This inclination is preferably identical for all the guide openings in the same row. It can also be the same or different between the rows.

In some embodiments, at least one guide opening, and preferably each guide opening, is fitted with a ring facilitating sliding. In particular, this ring may have a coefficient of kinetic friction lower than that of the peripheral surface of the sleeve. This ring can in particular be made of ceramic or Teflon.

In some embodiments, at least one guide opening, and preferably each guide opening, has a circular section.

In some embodiments, at least one guide opening, and preferably each guide opening, has a diameter between 5 and 10 mm. In some embodiments, at least one guide opening, and preferably each guide opening, is a section of a slot extending axially along the peripheral surface of the sleeve. Several sections of the same slot can thus form guide openings for different rows. This also makes it possible to control the angular distribution of the ribbons while allowing, if necessary, a degree of freedom axially.

In some embodiments, the distribution tool further comprises at least one guide ring extending transversely from the peripheral surface of the sleeve and comprising at least one eyelet cooperating with said at least one sleeve guide opening to guide a ribbon to guide the guiding rope. These eyelets make it possible to control the axial distribution of the ribbons when the guide openings take the form of slot sections.

In some embodiments, the distribution tool comprises a guide ring per row of guide openings.

In some embodiments, the guide ring of a row

given has as many eyelets as there are guide openings in this row.

In some embodiments, at least one eyelet is offset

tangentially to the guide opening with which it cooperates. This allows you to control the tangential inclination of the ribbons near the rope.

In other embodiments, at least one eyelet is aligned in the axial direction with the guide opening with which it cooperates.

In certain embodiments, the sleeve comprises a plurality of slots extending axially substantially all along the peripheral surface of the sleeve, the number of these slots being greater than the maximum number of guide openings provided within d 'one row. In other words, these slots extend over a space covering at least each of the rows of guide openings. Providing a larger number of slits makes it possible to offset the ribbons of a layer tangentially with respect to those of a neighboring layer or to adapt the same distribution tool to several applications using different numbers of ribbons.

In some embodiments, at least one guide ring is removable. The sleeve can thus be common to several applications and easily adapted by adding one or more suitable guide rings.

The present presentation also relates to a covering module, comprising a wheel mounted in rotation and provided with a central passage provided to allow the passage of a covering rope, at least one coil mounted on said wheel, and a tool distribution according to any one of the embodiments

previous, mounted on the wheel so that the axial passage of the sleeve of the distribution tool is centered on the axis of rotation of the wheel.

The present disclosure also relates to an installation for manufacturing a rope, comprising an axial drive device for the rope, and at least one wrapping module according to a previous embodiment.

In some embodiments, the installation includes several wrapping modules in this way, some can rotate clockwise and others counterclockwise.

In some embodiments, the installation comprises a module for supplying or producing a core, provided upstream of the first covering module.

The present presentation also relates to a method of manufacturing rope, using at least one covering module comprising

a wheel mounted in rotation and provided with a central passage,

a plurality of spools mounted on said wheel, and

a distribution tool mounted on said wheel, this distribution tool comprising a sleeve comprising a peripheral surface, an axial passage, centered on the axis of rotation of the wheel, and several rows of at least one guide opening, each opening guide extending between the peripheral surface and the axial passage,

in which a guiding cord passes through the central passage of the wheel and through the axial passage of the sleeve, and

in which at least one guide opening of a first row guides a first ribbon intended to guide the guiding rope and at least one guide opening of a second row guides a second ribbon intended to guide the guiding rope.

Naturally, all or part of the characteristics mentioned above with regard to the distribution tool, the covering module and / or the rope manufacturing installation can be transposed to this process.

In certain embodiments, each guide opening in each row guides a ribbon intended to guide the guiding rope.

In certain embodiments, certain ribbons intended to guide the

guiper rope include different materials. More specifically, the material of the fibers and / or the material of the matrix of these ribbons may be different. For example, the fibers of certain ribbons can be glass fibers; the fibers of other ribbons can be carbon fibers. Hybrid strings are thus obtained comprising several different materials.

In other embodiments, all the ribbons intended to guide the

guiper string include the same material.

In some embodiments, the core is produced in a first

material and all of the other layers are made of a second material, different from the first material.

In some embodiments, the layers wound in a first direction are made of a first material while the layers wound in a second direction are made of a second material, different from the first material. Here again, the fibers and / or the matrix of the layers may vary.

In some embodiments, the core is produced in a first

material, the layers wound in a first direction are made of a second material and that the layers wound in a second direction are made of a third material, these three materials being different.

The present description also relates to a composite cord comprising an axial core and a superposition of fibrous layers, wound

alternately clockwise and counterclockwise, each consisting one or more sublayers wound in the same direction,

wherein the odd rank layers include a first material while the even rank layers include a second material absent from the odd rank layers.

In some embodiments, the layers of odd rank include first fibers formed in a first material while the layers of even rank include second fibers formed in a second material. For example, the first fibers are glass fibers while the second fibers are carbon fibers, or vice versa.

In some embodiments, the core includes fibers of the same material as the layers of even rank.

In the present description, the terms "axial", "radial", "tangential",

"Interior", "exterior" and their derivatives are defined with respect to the main axis of the distribution tool, that is to say the axis of its axial passage, also corresponding to the direction of travel of the rope or the axis of rotation of the covering modules. The term "axial plane" means a plane passing through this main axis and by "radial plane" a plane perpendicular to this main axis; finally, the terms “upstream” and “downstream” are defined in relation to the running of the rope.

In the present description, the term "ribbon" means any type of structure

fibrous intended to be wound on the rope: it can in particular be single threads, bundles of threads, bands etc.

Description of the embodiments

In order to make the presentation more concrete, examples of distribution tools and rope manufacturing installations are described in detail below, with reference to the accompanying drawings. It is recalled that the invention is not limited to these examples.

FIG 1 shows a rope manufacturing installation 1 according to the description.

It comprises a core production module 10, provided at the upstream end of the installation 1, that is to say at the right end in FIG 1, a succession of covering modules 20, and a drive device 30, provided at the downstream end of the installation 1, that is to say at the left end of FIG 1.

The core embodiment module 10 comprises a wheel 1 1 provided with a

plurality of coils 12. A wire 13 is drawn from each coil 12 and the wheel 11 is rotated so as to rotate together the wires 13 of the different coils 12, thus forming a core strand 14. In the present example, the 'soul 14 takes the form of a strand of son turned together; however, the core 14 could also take the form of a braid, a rod, or even a tube.

The drive device 30 comprises a drum 31 driven in rotation by a motor. The free end of the core 14 is fixed on the drum 31 and the latter is rotated, which tends the core 14 and causes the latter to travel downstream before it is wound around the drum 31.

As can be seen in FIGs 1 and 2, each covering module 20 comprises a wheel 21 provided with a central passage 21 to Each covering module 20 is inserted between the core production module 10 and the device drive 30, the axis of rotation A of all the covering modules 20 being aligned with the axis of rotation of the core-making module 10. The core 14, and more generally the cord during manufacture 24 , thus crosses each covering module 20 by extending along the common axis of rotation A of all the modules 20 before being wound around the drum 31 of the device

30.

Each covering module 20 comprises one or more sets 22a, 22b, 22c of coils 22, each set of coils being intended to form a fibrous layer of the final cord 50. In the present example, for reasons of simplification of the description, the coils 22a, 22b, 22c are presented in separate plans; however, in practice it is possible to install all coils 22a, 22b, 22c in the same plane and then distribute their ribbons 23 in different rows using the distribution tool 40 and / or pulleys.

The ribbons 23 include a fibrous reinforcement impregnated with a matrix

organic, of the thermosetting type. In the present example, these are glass fibers impregnated with an epoxy resin; each ribbon takes the form of a strip 5 mm wide and 0.5 mm thick.

Each covering module 20 thus comprises a distribution tool 40

mounted in the center of the wheel 21, so that the main axis of the distribution tool 40 is aligned with the axis of rotation A of the wheel 21, and therefore with the direction of travel of the rope during manufacture 24. The distribution tool 40 rotates integrally with the wheel 21 of the covering module 20.

A first example of a distribution tool 40 is better visible in FIGS 3 to 7. It comprises a sleeve 41, substantially cylindrical, having a cylindrical peripheral surface 42 and a cylindrical axial passage 43. The distribution tool 40 is installed so that the rope during manufacture 24 extends axially along the axial passage 43.

The sleeve 41 further comprises guide openings 44 extending between the peripheral surface 42 and the axial passage 43. These guide openings 44 are organized in rows 44a, 44b, 44c in the axial direction, the sleeve 41 comprising as many rows 44a, 44b, 44c as the covering module 20 considered comprises sets of coils 22a, 22b, 22c, that is to say as many rows 44a, 44b, 44c as of fibrous layers deposited by the module covering considered 20. These rows 44a, 44b, 44c are separated by an axial distance d of at least 10mm, more precisely 15 mm in the present example.

Each row 44a, 44b, 44c includes as many guide openings 44 as coils 22 within the set 22a, 22b, 22c considered, that is to say as many guide openings 44 as ribbons 23 juxtaposed necessary to form the fibrous layer considered. Within each row 44a, 44b, 44c, the guide openings 44 are regularly spaced from one another in the circumferential direction, that is to say equitably distributed around the axial direction A: thus, in this example, rows 44a and 44b have each three guide openings 44 at 120 ° from each other while the row 44c has four guide openings 44 at 90 ° from each other.

Each guide opening 44 is inclined both in the axial direction, downstream, and in the tangential direction, in the direction opposite to the direction of rotation of the wheel 21. Thus, in the present example, the direction of the guide openings 44 forms an angle l of 5 ° with the radial direction in the radid plane and an angle m of 45 ° with the radial direction in the axial plane.

In addition, each guide opening 44 is equipped with a ring

sliding 45, made of ceramic, inserted in the guide opening 44.

Thus, from each coil 22 of the covering module 20 is pulled a ribbon 23 which is passed through its dedicated guide opening 44 before being applied to the rope during manufacture 24. Consequently, when the wheel 21 of the covering module 20 is rotated, the ribbons 23 of each reel 22 are deposited and wound around the rope during manufacture 24, for its part traveling from upstream to downstream using the drive device 30, so forming one or more additional fibrous layers on the rope during manufacture 24.

More specifically, the guide openings 44 of each row 44a, 44b, 44c guide the ribbons 23 intended to form the same fibrous layer so as to control their distribution around the rope during manufacture 24 and, thus, juxtapose the ribbons 23 of the same fibrous layer correctly without creating an overlap or void between the ribbons 23. In addition, the axial separation between the rows 44a, 44b, 44c makes it possible to separate the ribbons 23 intended for a fibrous layer from those intended for another fibrous layer so as to prevent them from interfering with each other; they also make it possible to control the locations of the rope at the level of which the different sets of ribbons will be deposited and, in particular, to ensure a sufficient interval between them to allow the stabilization of the layer

previous before depositing the next layer.

Thus, each covering module 20 makes it possible to add to the incoming rope a plurality of fibrous layers all wound in the same direction, consequently increasing the diameter of the rope during manufacture 24. In in particular, the successive covering modules 20 can rotate in opposite directions in order to deposit fibrous layers having directions

different windings.

Thus, wrapping module 20 after wrapping module 20, new

fibrous layers are deposited and the diameter of the rope 24 increases until it reaches a final rope 50 winding on the drum 31 of the drive device 30. In this respect, naturally, it is understood that the increase in the diameter of the rope 24 is exaggerated in FIG 1.

The structure of the final cord 50 thus obtained is visible in FIG 8. It comprises a core 59, extending in the axial direction A and having an axial orientation, and a superposition of fibrous layers 52-1, 52 -2, 52-3, 52-4, wound alternately clockwise and counterclockwise, each consisting of one or more sublayers wound in the same direction.

It can be noted in particular in this FIG 8 that once the rope 50 is finished, the interface between the different sub-layers can no longer, or can only with difficulty, be discerned so that one obtains layers 52-1, 52-2, 52-3, 52-4 substantially homogeneous. The thickness of these layers 52-1, 52-2, 52-3, 52-4 can however be variable depending on the number of sublayers that each of the layers 52-1, 52-2, 52-3 contains. 52-4 considered.

Incidentally, it should be noted that if FIG 8 represents only 4 layers, it is only for obvious reasons of simplification, the number of layers of such a rope 50 can naturally be greater.

In the example of FIG 8, all the ribbons used are made in the

same material and have the same dimensions: consequently, all the layers 52-1, 52-2, 52-3, 52-4 are homogeneous and therefore differ only in their orientation and, possibly, in their thickness depending on the number of sublayers they contain.

However, in other examples, certain layers could include ribbons of material and / or different dimensions. For example, FIG 9 illustrates a second example of a final rope 50 'also comprising an axial core 59' and a superposition of fibrous layers 52-1 ', 52-2', 52-3 ', 52-4', wound alternately clockwise and counterclockwise, each consisting of one or more underlayers wound in the same direction.

However, in this second example, the layers of odd rank 52-1 ', 52-3' are produced from ribbons of a first material, for example glass fibers, while the layers of even rank 52-2 ' , 52-4 ', as well as the core 59, are produced from ribbons made of a second material, for example carbon fibers.

Here again, the interface between the different sub-layers can no longer, or can only with difficulty, be discerned so that layers 52-1, 52-2, 52-3, 52 are obtained. -4 substantially homogeneous. On the other hand, the interface between the odd layers 52-1 ', 52-3' and pairs 52-2 ', 52-4' is all the more visible since, in addition to the change in orientation, the change in nature of the fibers.

FIGS 10 to 12 illustrate a second embodiment of a distribution tool 140 according to the description.

In this second example, the distribution tool 140 comprises a sleeve 141, substantially cylindrical, comprising a cylindrical peripheral surface 142 and a cylindrical axial passage 143.

The sleeve 141 further comprises slots 146 made in its

peripheral surface 142 axially along the sleeve 141, with the exception of its ends, and bringing the axial passage 143 into communication with the outside. In the present description, the sleeve 141 has twelve slots 146 equitably distributed in the circumferential direction.

The distribution tool 140 also includes guide rings 147a, 147b, 147c attached in radial planes around the sleeve 141, at an axial distance d constant from each other. The distribution tool 140 comprises as many guide rings 147a, 147b, 147c as the covering module 20 considered comprises sets of coils 22a, 22b, 22c, that is to say as many guide rings 147a , 147b, 147c as fibrous layers deposited by the covering module considered 20.

Each guide ring 147a, 147b, 147c includes eyelets 148, more precisely as many eyelets 148 as coils 22 within the set 22a, 22b, 22c considered, that is to say as many eyelets 148 as juxtaposed ribbons 23 necessary to form the fibrous layer considered. On the same guide ring 147a, 147b, 147c, the eyelets 148 are regularly spaced from each other in the circumferential direction.

Each ribbon 23 is engaged in an eyelet 148 and a section 146a, 146b,

146c of a slot 146 of the sleeve 141 located downstream of the guide ring 147a 147b, 147c considered and forming a guide opening 144 for the ribbon 23 considered.

The position of the eyelet 148 relative to the associated slot 146 makes it possible to

adjust the inclination of the ribbon 23 when it is deposited on the rope during manufacture 24.

The eyelets 148 can be fitted with sliding rings 145

analogous to those of the first example. An equivalent coating can also be deposited in the slots 146.

In addition to these structural differences, the distribution tool 140 of this second example works in a completely analogous manner to that of the first example.

Although the present invention has been described with reference to specific embodiments, it is obvious that modifications and

changes can be made to these examples without departing from the general scope of the invention as defined by the claims. In particular, individual characteristics of the different embodiments

illustrated / mentioned can be combined in additional embodiments. Therefore, the description and the drawings must be

considered in an illustrative rather than restrictive sense.

It is also obvious that all the characteristics described with reference to a method can be transposed, alone or in combination, to a device, and conversely, all the characteristics described with reference to a device can be transposed, alone or in combination, to a method.
