Description

L'invention est relative à un touret pour le déroulement de couronnes de tubes, de profilés ou autres, en particulier en matière plastique, du genre de ceux qui comprennent deux flasques d'extrémité et un moyeu s'étendant suivant toute la longueur axiale, au moins l'un des flasques d'extrémité étant démontable , et au moins un flasque intermédiaire déterminant, entre les flasques d'extrémité, des logements séparés pour au moins deux couronnes différentesThe invention relates to a drum for the unwinding of tube crowns, profiles or others, especially plastic, like those include two end flanges and a hub extending along the entire axial length, at least one end flanges being removable, and at least one determining intermediate flange, between the flanges end, separate accommodation for at least two different crowns

Des tourets sont utilisés, notamment, pour la pose de tubes en matière plastique servant de gaines pour les câbles téléphoniques. Les longueurs de tubes à mettre en place sont généralement importantes et le diamètre extérieur des tourets peut dépasser deux mètres pour recevoir des couronnes correspondant à une longueur suffisamment élevée de tube plastique. Pour le déroulement du tube, le touret est monté rotatif sur un support, généralement prévu sur un engin de transport tel qu'une remorque ou un camion.Drums are used, in particular, for laying plastic tubes serving as sheaths for telephone cables. The lengths of tubes to be used places are usually important and the diameter outside of the drums can exceed two meters for receive crowns corresponding to a length sufficiently high plastic tube. For the course of the tube, the reel is rotatably mounted on a support, generally provided on a transport unit such as a trailer or truck.

On connaít, d'après AT-B-40 860 et FR-A-386 350, un dévidoir pliant comprenant deux roues et un ou plusieurs disques intermédiaires pour permettre de dévider différentes espèces de fils. Les deux roues sont réunies de manière démontable à l'aide de plusieurs tringles vissées dans des coulisses délimitées par des bras s'étendant suivant des rayons de chaque roue. Lors du pliage, on enlève les roues de l'arbre qui les porte en position de travail. Les tringles définissent un contour d'enroulement polygonal, avec aux sommets des changements de direction relativement brusques susceptibles de dégrader les produits enroulés, en particulier s'il s'agit de tubes en matière plastique . La mise en place des produits sur les tringles n'est en outre pas décrite. We know, from AT-B-40 860 and FR-A-386 350, a folding dispenser comprising two wheels and one or more intermediate discs to allow unwinding different kinds of yarn. The two wheels are joined together removable way using several screwed rods behind the scenes delimited by arms extending along spokes of each wheel. When folding, we remove the wheels from the shaft which brings them to the position job. Rods define a winding contour polygonal, with direction changes at the vertices relatively abrupt likely to degrade products wound, in particular in the case of tubes made of material plastic. The installation of products on the rods is also not described.

L'invention a pour but, surtout de fournir un touret de construction simple et économique, permettant une mise en place facile et rapide d'un nombre variable de couronnes de tubes sur le touret pour permettre un déroulement simultané de plusieurs tubes, ou profilés, destinés à différentes applications.The object of the invention is, above all to provide a simple and economical construction reel, allowing quick and easy installation of a variable number of tube crowns on the reel to allow simultaneous unwinding of several tubes, or profiles, for different applications.

Selon l'invention, un touret du genre défini précédemment est caractérisé par le fait que l'autre flasque d'extrémité du touret est fixe et solidaire d'un tambour sur lequel peut être engagée la (les) couronne (s), que le moyeu est un moyeu tubulaire central solidaire de ce flasque d'extrémité fixe, coaxial à l'intérieur du tambour et muni à une extrémité de moyens de fixation rapide pour le flasque démontable , qu'au moins un anneau formant le flasque intermédiaire est engagé sur le tambour et que des moyens de blocage du ou des flasques intermédiaires relativement au tambour sont prévus. According to the invention, a reel of the defined kind previously characterized by the fact that the other end flange of the reel is fixed and secured to a drum on which the crown (s) can be engaged, that the hub is a central tubular hub integral with this fixed end flange, coaxial inside the drum and provided at one end with quick fastening means for the removable flange, that at least one ring forming the intermediate flange is engaged on the drum and only means for blocking the intermediate flange (s) relative to the drum are provided.

Le nombre de flasques intermédiaires engagés sur le tambour est de préférence au moins égal à deux pour déterminer au moins trois logements annulaires séparés.The number of intermediate flanges engaged on the drum is preferably at least two for identify at least three separate annular housings.

Généralement l'autre flasque d'extrémité du touret est fixe et solidaire du tambour et le moyeu tubulaire central est solidaire de ce flasque d'extrémité fixe.Usually the other end flange of the drum is fixed and integral with the drum and the tubular hub central is integral with this fixed end flange.

Les moyens de blocage des flasques intermédiaires comprennent, de préférence, au moins un élément, en particulier un tube, solidaire du flasque fixe, en saillie parallèlement à l'axe du tambour à partir du flasque fixe, et situé radialement à l'intérieur de la paroi du tambour, laquelle paroi comporte au moins une fente longitudinale ayant même position angulaire que cet élément, tandis que chaque flasque intermédiaire comprend au moins une tige en saillie radialement vers l'intérieur, munie à son extrémité tournée vers le centre d'une fourche équipée d'un moyen de serrage, cette tige étant destinée à être engagée dans la fente longitudinale du tambour, l'ensemble étant tel que la fourche de la tige vient coiffer ledit élément en saillie solidaire du flasque fixe qui peut être serré entre les branches de cette fourche.Means for blocking intermediate flanges preferably include at least one element, in in particular a tube, integral with the fixed flange, projecting parallel to the axis of the drum from the fixed flange, and located radially inside the wall of the drum, which wall has at least one longitudinal slot having the same angular position as this element, while each intermediate flange comprises at least one rod in radially inwardly projecting, provided at its end facing the center of a fork fitted with a means of tightening, this rod being intended to be engaged in the longitudinal slot of the drum, the assembly being such that the stem fork covers said protruding element secured to the fixed flange which can be clamped between the branches of this fork.

Généralement deux tiges en saillie radialement vers l'intérieur, équipées chacune d'une fourche de serrage et diamétralement opposées, sont prévues sur chaque flasque intermédiaire, tandis que deux fentes correspondantes diamétralement opposées sont prévues dans la paroi du tambour ; deux éléments en saillie à partir du flasque fixe sont en outre prévus en correspondance avec ces fentes, pour assurer le blocage du flasque intermédiaire.Generally two rods projecting radially towards inside, each equipped with a clamping fork and diametrically opposed, are provided on each flange intermediate, while two corresponding slots diametrically opposed are provided in the wall of the drum; two elements projecting from the fixed flange are also provided in correspondence with these slots, to block the intermediate flange.

De préférence, vers l'extrémité du moyeu éloignée du flasque fixe, des rayons de soutien sont prévus partant du moyeu et fixés, à leur extrémité éloignée du moyeu, contre la face interne de la paroi du tambour.Preferably towards the far end of the hub fixed flange, supporting radii are provided of the hub and fixed, at their end remote from the hub, against the inside of the drum wall.

Chaque élément de blocage en saillie axiale à partir du flasque fixe est compris angulairement entre deux rayons de soutien et une barre d'appui, s'étendant suivant une corde entre deux rayons de soutien, est reliée rigidement au dit élément en saillie.Each locking element projecting axially from the fixed flange is angularly between two support spokes and a support bar, extending along a cord between two support spokes is connected rigidly to said projecting element.

Les moyens de fixation rapide du flasque démontable peuvent comprendre, du côté du moyeu, un manchon central mâle muni, sur sa surface extérieure, d'un logement parallèle à l'axe, pour une clavette, et du côté du flasque mobile un manchon central femelle muni d'une rainure parallèle à l'axe propre à recevoir une partie de la clavette lorsque le manchon femelle est engagé sur le manchon mâle, de sorte qu'un blocage en rotation du flasque démontable sur le moyeu est ainsi obtenu ; des moyens de retenue axiale sont en outre prévus entre le moyeu et le flasque démontable.The means of rapid fixing of the removable flange may include, on the hub side, a central sleeve male provided with a housing on its outer surface parallel to the axis, for a key, and on the side of the flange mobile a central female sleeve provided with a groove parallel to the proper axis to receive part of the key when the female sleeve is engaged on the male sleeve, so that a rotation blocking of the flange removable on the hub is thus obtained; ways to axial retainers are also provided between the hub and the removable flange.

Ces moyens de retenue axiale peuvent comprendre une bague, ou crabot, engagée en bout de moyeu, cette bague comportant un trou taraudé radial avec lequel une vis coopère et fait saillie, par un pion d'extrémité, dans l'alésage de la bague, le manchon mâle du moyeu comportant une rainure parallèle à l'axe débouchant, en retrait de l'extrémité du moyeu, dans une rainure en arc de cercle propre à recevoir le pion de la vis, grâce à un déplacement en translation suivi d'une rotation entre la bague et le moyeu.These axial retaining means may include a ring, or dog clutch, engaged at the end of the hub, this ring having a radial tapped hole with which a screw cooperates and protrudes, by an end pin, in the bore of the ring, the male sleeve of the hub comprising a groove parallel to the through axis, set back from the end of the hub, in an arcuate groove suitable for receiving the screw pin, thanks to a displacement in translation followed by a rotation between the ring and the hub.

Avantageusement, la paroi du tambour est composée d'un nombre pair de pales, supérieur à deux, en particulier égal à huit, chaque pale ayant la forme d'un secteur cylindrique, et étant séparée des deux pales voisines par une fente. Les génératrices des pales peuvent présenter une légère inclinaison conique , notamment pour faciliter l'engagement des couronnes sur le tambour.Advantageously, the wall of the drum is composed an even number of blades, greater than two, in particular equal to eight, each blade having the shape of a sector cylindrical, and being separated from the two neighboring blades by a slit. The generators of the blades may have a slight conical tilt, especially to facilitate the engagement of the crowns on the drum.

Selon une réalisation particulièrement simple, chaque flasque d'extrémité comprend des tubes, en particulier à section carrée, partant d'un manchon central et formant des rayons reliés deux à deux, dans leur zone d'extrémité éloignée du centre, par des plaques en forme de trapèze, en particulier soudées aux rayons, tandis que la face du flasque située vers l'intérieur du touret est formée par un anneau continu dont le diamètre intérieur est sensiblement égal à celui du tambour.According to a particularly simple embodiment, each end flange comprises tubes, in particular with square section, starting from a central sleeve and forming rays linked two by two, in their area far away from the center, by plates in the form of trapezium, in particular welded to the spokes, while the face of the flange located towards the inside of the east drum formed by a continuous ring whose inner diameter is substantially equal to that of the drum.

Les rayons du flasque d'extrémité fixe sont situés à mi-distance angulaire entre les fentes séparant les pales du tambour, tandis que les moyens de fixation du flasque démmontable sur le moyeu sont agencés pour qu'en position fixe du flasque démontable, les rayons de ce flasque démontable soient engagés dans les extrémités des fentes du tambour.The spokes of the fixed end flange are located half angular distance between the slots separating the blades of the drum, while the means for fixing the flange removable on the hub are arranged so that in position fixed of the removable flange, the spokes of this flange removable are engaged in the ends of the slots of the drum.

Le diamètre extérieur des flasques intermédiaires est, de préférence, inférieur au diamètre extérieur des flasques d'extrémité.The outside diameter of the intermediate flanges is preferably less than the outside diameter of the end flanges.

Le diamètre du tambour peut atteindre et dépasser 150 cm, tandis que le diamètre des flasques d'extrémité peut atteindre et dépasser 250 cm. La longueur du tambour est choisie en fonction du nombre de flasques intermédiaires que l'on souhaite pouvoir installer sur ce tambour. Dans le cas de la mise en place de deux flasques intermédiaires, conduisant à trois logements pour trois couronnes différentes, la longueur du tambour est de l'ordre de 100 cm.Drum diameter can reach and exceed 150 cm, while the diameter of the end flanges can reach and exceed 250 cm. The length of the drum is chosen according to the number of flanges intermediaries that we want to be able to install on this drum. In the case of the installation of two flanges intermediaries, leading to three dwellings for three different crowns, the length of the drum is around 100 cm.

    • En se reportant aux dessins, notamment aux figures 1 et 2, on peut voir un touret 1 pour le déroulement de couronnes C de tubes, profilés ou autres, en matière plastique.Referring to the drawings, in particular to the figures 1 and 2, you can see a drum 1 for the progress of crowns C of tubes, profiles or the like, of material plastic.

    Le touret comprend un tambour 2, c'est à dire un cylindre de révolution, sur lequel sont engagées les couronnes C, deux flasques d'extrémité 3, 4 pour maintenir axialement les couronnes sur le tambour, et un moyeu 5 coaxial à l'intérieur du tambour 2.The drum comprises a drum 2, that is to say a cylinder of revolution, on which are engaged the crowns C, two end flanges 3, 4 to hold axially the crowns on the drum, and a hub 5 coaxial inside the drum 2.

    Le flasque 3 est fixe et solidaire du tambour 2. L'autre flasque d'extrémité 4 est démontable. Le moyeu 5 s'étend suivant toute la longueur axiale du tambour 2 et est muni, à son extrémité éloignée du flasque fixe 3, de moyens de fixation rapide F pour le flasque démontable 4. Dans l'exemple représenté sur la figure 2, deux anneaux 6, formant flasques intermédiaires, sont engagés sur le tambour 2 pour déterminer entre les flasques d'extrémité 3, 4 et entre les deux flasques intermédiaires 6, trois logements séparés pour trois couronnes différentes de tubes Ta, Tb, Tc. Des moyens de blocage B de chaque flasque intermédiaire 6 relativement au tambour 2 sont prévus.The flange 3 is fixed and integral with the drum 2. The other end flange 4 is removable. Hub 5 extends along the entire axial length of the drum 2 and is provided, at its end remote from the fixed flange 3, with quick fixing means F for the removable flange 4. In the example shown in FIG. 2, two rings 6, forming intermediate flanges, are engaged on the drum 2 to determine between the end plates 3, 4 and between the two intermediate flanges 6, three separate housings for three different tube crowns Ta, Tb, Tc. Blocking means B of each flange intermediate 6 relative to the drum 2 are provided.

    Les moyens de blocage B comprennent, solidaires du tambour et du flasque fixe 3, deux éléments 7 en saillie parallèlement à l'axe du tambour à partir du flasque fixe 3. Les deux éléments 7 sont diamétralement opposés et situés radialement à l'intérieur de la paroi du tambour 2. La paroi de ce tambour comporte, suivant le même diamètre que les éléments 7, deux fentes longitudinales opposées 8 (fig. 1) s'étendant suivant toute la longueur du tambour et débouchant à l'extrémité éloignée du flasque fixe 3. Les fentes 8 peuvent être obtenues en rabattant vers l'intérieur des zones de largeur sensiblement moitié de celle de la fente, de part et d'autre d'un trait de coupe.The blocking means B comprise, integral with the drum and fixed flange 3, two projecting elements 7 parallel to the axis of the drum from the fixed flange 3. The two elements 7 are diametrically opposed and located radially inside the wall of the drum 2. The wall of this drum has, according to the same diameter as the elements 7, two opposite longitudinal slots 8 (fig. 1) extending along the entire length of the drum and opening at the far end of the fixed flange 3. The slots 8 can be obtained by folding back towards inside areas of width substantially half of that of the slot, on either side of a cutting line.

    Chaque élément 7 est avantageusement constitué par un tube carré dont l'extrémité 9, du côté du flasque 3, est recourbée à angle droit et soudée sur une barre transversale 10 s'étendant suivant une corde, entre deux rayons 11, 12, constitués par des tubes à section carrée ou rectangulaire , du flasque d'extrémité 3.Each element 7 is advantageously constituted by a square tube whose end 9, on the side of the flange 3, is bent at right angles and welded to a bar transverse 10 extending along a cord, between two spokes 11, 12, consisting of square section tubes or rectangular, end flange 3.

    Le moyeu 5 comporte, à distance du flasque fixe 3, des rayons de soutien 13, constitués par des tubes à section carrée ou rectangulaire, situés dans un plan moyen orthogonal à l'axe géométrique du moyeu 5 et régulièrement espacés angulairement. Ces rayons 13 sont solidaires du moyeu 5, notamment par soudure et sont fixés, également par soudure, à leur autre extrémité contre la face interne du tambour 2. Dans l'exemple considéré, ces rayons 13 sont au nombre de huit et ont même disposition angulaire que les rayons 11, 12 du flasque fixe. L'élément en saillie 7 est compris angulairement entre deux rayons 13 à égale distance et s'étend au delà du plan des rayons 13, comme visible sur la figure 2. L'extrémité de l' élément 7 est à l'intérieur du tambour 2, en retrait de l'autre flasque d'extrémité 4. The hub 5 comprises, at a distance from the fixed flange 3, support spokes 13, constituted by tubes with square or rectangular section, located in a medium plane orthogonal to the geometric axis of the hub 5 and regularly angularly spaced. These spokes 13 are integral with the hub 5, in particular by welding and are fixed, also by solder, at their other end against the internal face of the drum 2. In the example considered, these spokes 13 are at number eight and have the same angular layout as the spokes 11, 12 of the fixed flange. The protruding element 7 is angularly between two rays 13 at equal distance and extends beyond the plane of the rays 13, as visible on Figure 2. The end of element 7 is inside of the drum 2, set back from the other end flange 4.

    Une barre d'appui 14 s'étend suivant une corde entre deux rayons 13 parallèlement à la barre 10 et de préférence à même distance radiale de l'axe du moyeu 5. L'élément 7 est relié rigidement par une entretoise soudée 15 à la barre d'appui 14.A support bar 14 extends along a rope between two spokes 13 parallel to the bar 10 and preferably at the same radial distance from the hub axis 5. Element 7 is rigidly connected by a welded spacer 15 to the support bar 14.

    Chaque flasque intermédiaire comprend deux tiges 16 diamétralement opposées, avantageusement formées par une longueur de tube à section carrée, en saillie radialement vers l'intérieur de chaque flasque intermédiaire 6. Les deux tiges 16 d'un même flasque 6 sont diamétralement opposées. L'extrémité tournée vers le centre de chaque tige 16 est munie d'une fourche 17 propre à venir coiffer l'élément 7 avec possibilité de coulissement relatif. Chaque fourche 17 est équipée d'un moyen de serrage, par exemple une vis 18 à oreilles, vissée dans un trou taraudé d'une des branches de la fourche 17 et orientée orthogonalement à la direction longitudinale de l'élément 7.Each intermediate flange includes two rods 16 diametrically opposite, advantageously formed by a tube length with square section, radially projecting inward of each intermediate flange 6. The two rods 16 of the same flange 6 are diametrically opposite. The end facing the center of each rod 16 is provided with a fork 17 suitable for styling element 7 with possibility of relative sliding. Each fork 17 is equipped with a clamping means, by example an 18 wing screw, screwed into a tapped hole of one of the branches of the fork 17 and oriented orthogonally to the longitudinal direction of the element 7.

    Les bords intérieur et extérieur, dans le sens radial, des flasques intermédiaires 6 sont constitués par des tubes 19, 20 à section circulaire, cintrés suivant le contour des flasques. La présence de ces tubes 19, 20 permet d'éviter toute arête vive susceptible d'endommager les tubes en matière plastique lors du déroulement.Inner and outer edges, in the direction radial, intermediate flanges 6 are constituted by tubes 19, 20 with circular section, bent according to the contour of the flanges. The presence of these tubes 19, 20 avoids any sharp edges liable to damage plastic tubes during unwinding.

    Le tambour 2 comporte un nombre pair de fentes 8, au moins égal à deux. Dans l'exemple de réalisation illustré sur les dessins, le nombre de ces fentes est égal à huit. Les positions angulaires des fentes 8 correspondent aux bissectrices des angles formés par les rayons 11, 12 du flasque fixe 3. Le tambour 2 est ainsi constitué par huit pales 21, en forme de secteur cylindrique, en saillie à partir du flasque fixe 3, et supportées au voisinage de leur extrémité, à mi-largeur, par les rayons 13. De préférence, les pales 21 présentent une légère inclinaison, par exemple de 5/1000, de manière à se rapprocher de l'axe à partir du flasque fixe 3. Cette inclinaison facilite la mise en place des couronnes de tubes sur le tambour 2. The drum 2 has an even number of slots 8, at least two. In the example of realization illustrated in the drawings, the number of these slots is equal at eight. The angular positions of the slots 8 correspond to the bisectors of the angles formed by the rays 11, 12 of the fixed flange 3. The drum 2 is thus constituted by eight blades 21, in the shape of a cylindrical sector, projecting from from the fixed flange 3, and supported in the vicinity of their end, half-width, by the spokes 13. De preferably, the blades 21 have a slight inclination, for example from 5/1000, so as to approach the axis from the fixed flange 3. This inclination facilitates the placement of tube crowns on the drum 2.

    Le flasque démontable 4 comprend un manchon central femelle 22 d'où partent des rayons 23, formés par des tubes à section carrée, en nombre égal à celui des rayons 11, 12 du flasque fixe 3. Les rayons de chaque flasque sont reliés deux à deux , dans leur zone éloignée de l'axe du tambour, du côté extérieur du touret, par des plaques P en forme de trapèze isocèle, soudées aux rayons suivant les deux côtés du trapèze. Vers l'intérieur du touret, les rayons des flasques 3 et 4 sont soudés à un anneau continu respectivement 24, 25 dont le diamètre intérieur est égal ou supérieur au diamètre extérieur du tambour 2. Cet anneau détermine une surface interne lisse pour les deux logements compris entre les flasques d'extrémité et les flasques intermédiaires 6.The removable flange 4 includes a central sleeve female 22 from which rays 23 emerge, formed by tubes with square section, equal in number to that of spokes 11, 12 of the fixed flange 3. The spokes of each flange are connected two by two, in their zone far from the axis of the drum, on the outside of the drum, by P-shaped plates isosceles trapezoid, welded to spokes on both sides of the trapeze. Towards the inside of the drum, the radii of flanges 3 and 4 are welded to a continuous ring respectively 24, 25 whose internal diameter is equal or greater than the outside diameter of the drum 2. This ring determines a smooth internal surface for the two housings between the end flanges and the flanges intermediaries 6.

    Le contour circulaire extérieur des flasques d'extrémité 3 et 4 est formé par un tube 26 à section carrée ou rectangulaire, cintré suivant la circonférence et constituant une bande de roulement du touret sur le sol. Le diamètre extérieur de cette bande de roulement est supérieur au diamètre extérieur des flasques intermédiaires 6.The outer circular outline of the flanges end 3 and 4 is formed by a section tube 26 square or rectangular, curved along the circumference and constituting a tread of the drum on the ground. The outer diameter of this tread is greater than the outside diameter of the intermediate flanges 6.

    Les moyens de fixation rapide F comprennent, du côté du moyeu 5, un manchon central mâle 27. Ce manchon 27 comporte un alésage dans lequel est engagée l'extrémité du moyeu 5, sur lequel est soudé le manchon. Le diamètre extérieur du manchon 27 est égal, aux tolérances près, au diamètre intérieur de l'alésage du manchon femelle 22 qui peut ainsi être engagé sur ce manchon 27.The quick fixing means F include, side of the hub 5, a central male sleeve 27. This sleeve 27 has a bore into which the end of the hub 5, on which the sleeve is welded. The diameter outside of sleeve 27 is equal, except for tolerances, to internal diameter of the bore of the female sleeve 22 which can thus be engaged on this sleeve 27.

    Le manchon 27 est muni, à son extrémité arrière, d'une collerette 28 et comporte, sur sa paroi cylindrique externe, un logement 29 à bords parallèles aux génératrices du manchon . Le logement 29 peut recevoir une clavette 30 montrée sur la figure 11. La profondeur du logement 29 est inférieure à l'épaisseur de la clavette 30 qui, lorsqu'elle est placée dans ce logement 29, fait saillie sur la surface cylindrique extérieure du manchon 27. La partie en saillie de la clavette 30 peut s'engager dans une rainure 31 (figure 8) prévue dans l'alésage du manchon femelle 22 du flasque démontable 4. Le blocage en rotation du manchon femelle 22 relativement au manchon 27 est assuré par cette clavette 30. A mi-longueur du logement 29 et de la clavette 30 un trou taraudé respectivement 32, 33 propre à recevoir une vis peut être prévu.The sleeve 27 is provided, at its rear end, a flange 28 and comprises, on its cylindrical wall external, a housing 29 with edges parallel to the generators of the sleeve. The housing 29 can receive a key 30 shown in Figure 11. The depth of the housing 29 is less than the thickness of the key 30 which, when is placed in this housing 29, protrudes from the surface outer cylindrical of the sleeve 27. The projecting part of the key 30 can engage in a groove 31 (Figure 8) provided in the bore of the female sleeve 22 of the removable flange 4. Locking in rotation of the sleeve female 22 relative to the sleeve 27 is provided by this key 30. Halfway through the housing 29 and the key 30 a tapped hole respectively 32, 33 suitable for receiving a screw can be provided.

    La longueur axiale de la partie du manchon 27, situé en avant de la collerette 28, est supérieure à la longueur axiale du manchon 22.The axial length of the part of the sleeve 27, located in front of the flange 28, is greater than the axial length of the sleeve 22.

    L'extrémité du manchon 27, qui fait saillie au delà du manchon 22 lorsque ce dernier est en butée axiale contre la collerette 28, comporte deux rainures 34a, 34b diamétralement opposées, parallèles à l'axe du manchon. Ces rainures débouchent, à leur extrémité intérieure, dans une rainure associée 35a, 35b en arc de cercle s'étendant par exemple sur 30°. Les deux rainures en arc de cercle 35a, 35b sont également diamétralement opposées, comme visible sur la figure 7.The end of the sleeve 27, which projects beyond of the sleeve 22 when the latter is in axial abutment against the collar 28, has two grooves 34a, 34b diametrically opposite, parallel to the axis of the sleeve. These grooves open at their inner end into a associated groove 35a, 35b in an arc extending by example on 30 °. The two arcuate grooves 35a, 35b are also diametrically opposite, as visible in figure 7.

    Une bague 36, ou crabot, (voir figure 10) est prévue pour être montée en bout du manchon mâle 27. Cette bague 36 comporte, à mi-longueur, deux trous taraudés diamétralement opposés 37a, 37b. Une vis 38 à tête moletée est propre à coopérer avec l'un des trous 37a, 37b. L'extrémité de la vis éloignée de la tête comporte un pion 39 propre à faire saillie dans l'alésage de la bague 36 et à s'engager dans la rainure 34a ou 34b puis dans la rainure 35a ou 35b grâce à un déplacement en translation suivi d'une rotation entre la bague 36 et le manchon 27.A ring 36, or dog clutch, (see Figure 10) is intended to be mounted at the end of the male sleeve 27. This ring 36 has, at mid-length, two tapped holes diametrically opposed 37a, 37b. A knurled head screw 38 is suitable for cooperating with one of the holes 37a, 37b. The end of the screw away from the head has a pin 39 suitable for projecting into the bore of the ring 36 and to engage in the groove 34a or 34b then in the groove 35a or 35b thanks to a displacement in translation followed of a rotation between the ring 36 and the sleeve 27.

    Les cotes des différents éléments sont telles que lorsque le manchon 22 est en appui contre la collerette 28, la bague 36 est en appui contre la face avant du manchon 22 lorsque le pion 39 est logé dans la rainure 35a ou 35b (voir figure 5).The ratings of the different elements are such that when the sleeve 22 is in abutment against the flange 28, the ring 36 is in abutment against the front face of the sleeve 22 when the pin 39 is housed in the groove 35a or 35b (see figure 5).

    L'ensemble de ces éléments constitue des moyens de retenue axiale du manchon femelle 22 relativement au manchon mâle 27. All of these elements constitute means of axial retention of the female sleeve 22 relative to the male sleeve 27.

    En vissant la vis 38 dans le trou taraudé 37a ou 37b, on peut exercer une pression par le pion 39 contre le fond de la gorge 35a ou 35b de sorte que la bague 36 se trouve également bloquée en rotation.By screwing the screw 38 into the tapped hole 37a or 37b, pressure can be exerted by the pin 39 against the bottom of the throat 35a or 35b so that the ring 36 is also finds it locked in rotation.

    On peut prévoir, comme visible sur la figure 2, des crochets 40 fixés contre la surface interne d'une pale du tambour 2, le long d'une génératrice.As can be seen in FIG. 2, it is possible to provide hooks 40 fixed against the internal surface of a blade of the drum 2, along a generator.

    Ceci étant les opérations de mise en place des couronnes de tubes sur le touret et le fonctionnement de ce touret sont les suivants.This being the operations of setting up the tube crowns on the reel and the operation of this reel are as follows.

    Pour la mise en place de la première couronne de tube Ta on démonte, au préalable, le flasque 4 et les anneaux intermédiaires 6 ; on peut alors engager axialement la couronne de tube Ta sur le tambour 2. Cette opération s'effectue manuellement ou à l'aide de moyens de levage selon le poids de la couronne. Le flasque 3 est maintenu dans un plan sensiblement vertical.For the installation of the first crown of Ta tube we dismantle, beforehand, the flange 4 and the intermediate rings 6; we can then engage axially the tube crown Ta on the drum 2. This operation is done manually or using lifting means depending on the weight of the crown. The flange 3 is maintained in a substantially vertical plane.

    Un premier flasque intermédiaire 6 est ensuite mis en place en engageant les tiges 16 dans les fentes 8 diamétralement opposées du tambour 2, situées au droit des éléments en saillie 7 qui sont reçus dans les fourches 17. On fait coulisser axialement le flasque 6 jusqu'à la couronne de tube Ta et on bloque ce flasque 6 sur les éléments 7 en serrant ces derniers dans les fourches 17 à l'aide des vis 18.A first intermediate flange 6 is then put in place by engaging the rods 16 in the slots 8 diametrically opposite of the drum 2, located to the right of the protruding elements 7 which are received in the forks 17. The flange 6 is made to slide axially up to the tube crown Ta and we block this flange 6 on the elements 7 by tightening these in the forks 17 to using screws 18.

    On met ensuite en place la deuxième couronne de tube Tb autour du tambour 2 jusqu'à venir en appui axial contre le premier flasque intermédiaire 6.We then put in place the second crown of tube Tb around the drum 2 until it comes to axial support against the first intermediate flange 6.

    Puis on installe le deuxième flasque intermédiaire 6 comme expliqué pour le premier.Then we install the second intermediate flange 6 as explained for the first.

    Enfin, on met en place la troisième couronne de tube Tc sur l'extrémité du tambour 2 et on assemble le flasque démontable 4 avec l'extrémité du moyeu 5.Finally, we put in place the third crown of Tc tube on the end of the drum 2 and we assemble the removable flange 4 with the hub end 5.

    Pour cela, après avoir placé la clavette 30 dans le logement 29 du manchon 27, on présente le flasque 4 de telle sorte que la rainure 31 de son manchon 22 reçoive la partie extérieure de la clavette 30. On fait coulisser le flasque 4 jusqu'à ce que le manchon 22 vienne en appui contre la collerette 28. Il est à noter que la position angulaire déterminée par la clavette 30 et la rainure 31 est telle que les rayons 23 du flasque 4 viennent s'engager dans les extrémités des fentes 8 du tambour. Les rayons 23 sont ainsi orientés suivant les bissectrices des angles formés par les rayons 11, 12 du flasque fixe 3.For this, after placing the key 30 in the housing 29 of sleeve 27, the flange 4 of so that the groove 31 of its sleeve 22 receives the outer part of the key 30. We slide the flange 4 until the sleeve 22 comes to bear against the flange 28. It should be noted that the position angular determined by the key 30 and the groove 31 is such that the spokes 23 of the flange 4 engage in the ends of the slots 8 of the drum. Rays 23 are thus oriented along the bisectors of the angles formed by the spokes 11, 12 of the fixed flange 3.

    On assure ensuite le blocage axial du manchon 22 en mettant en place la bague 36 équipée de la vis 38, par un mouvement de coulissement axial suivi d'une rotation, comme expliqué précédemment.It then ensures the axial locking of the sleeve 22 in setting up the ring 36 fitted with the screw 38, by a axial sliding movement followed by rotation, as explained previously.

    Les extrémités intérieures des tubes de chaque couronne peuvent être attachées au tambour 2, notamment aux crochets 40, pour éviter un glissement des couronnes lors du déroulement des tubes.The inner ends of the tubes of each crown can be attached to the drum 2, in particular to the hooks 40, to prevent sliding of the crowns during of the unwinding of the tubes.

    Le touret 1, ainsi équipé de trois couronnes de tubes, est ensuite installé sur un porte-touret muni d'un arbre propre à traverser le moyeu 5 pour permettre la rotation de l'ensemble du touret 1.Reel 1, thus equipped with three crowns tubes, is then installed on a reel holder fitted with a clean shaft through the hub 5 to allow the rotation of the entire reel 1.

    On peut alors dérouler simultanément les trois tubes Ta, Tb, Tc pour leur pose, par exemple dans une tranchée.We can then unroll the three simultaneously Ta, Tb, Tc tubes for their installation, for example in a trench.

    Le touret de l'invention est d'une construction simple et sa mise en oeuvre est rapide. Il permet de ne travailler qu'avec un seul engin porte-touret se trouvant sur le chantier de pose des tubes.The reel of the invention is of a construction simple and its implementation is fast. It does not work with only one reel-holding machine located on the pipe laying site.

    Le touret permet d'effectuer des économies de transport à l'aller puisque seuls les tubes en couronnes sont à transporter par camion ; ils peuvent être transportés en quantité importante ce qui réduit le coût du transport. En outre il n'y a aucuns frais de retour du touret vers le lieu de fabrication des couronnes de tubes.The reel saves transport to go since only the tubes in crowns are to be transported by truck; they can be transported in large quantities which reduces the cost of transport. In addition there is no cost of returning the reel to the place of manufacture of the tube crowns.

    Le touret permet de gagner de l'espace sur le chantier et de dérouler simultanément plusieurs couronnes de tubes.The reel saves space on the site and unroll several crowns simultaneously of tubes.

    Il s'adresse à tous types de tubes ou de profilés en matière plastique pouvant être enroulés, par exemple en polyéthylène (PE), en chlorure de polyvinyle (PVC), en polypropylène (PP).It is suitable for all types of tubes or profiles of plastic which can be rolled up, for example in polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP).

    2. Reel according to Claim 1, characterized in that the number of intermediate plates (6) fitted onto the drum (2) is at least equal to two, so as to define at least three separate annular housings.
    3. Reel according to Claim 1 or 2, characterized in that the means (B) of immobilizing the intermediate plates (6) comprise at least one element (7), particularly a tube, secured to the fixed plate (3), projecting parallel to the axis of the drum (2) from the fixed plate and lying radially inside the wall of the drum, which wall has at least one longitudinal slot (8) in the same angular position as this element (7), while each intermediate plate (6) comprises at least one rod (16) projecting radially inwards and, at its end facing towards the centre, fitted with a fork (17) equipped with a clamping means (18), this rod (16) being intended to engage in the longitudinal slot (8) in the drum, the assembly being such that the fork (17) of the rod sits over the said projecting element (7) secured to the fixed plate, which can be clamped between the branches of this fork.
    4. Reel according to Claim 3, characterized in that there are two diametrically opposed rods (16) projecting radially inwards, each equipped with a clamping fork (17) on each intermediate plate (6), while there are two corresponding diametrically opposed slots (8) in the wall of the drum, with two corresponding projecting elements (7).
    5. Reel according to one of Claims 1 to 4, characterized in that the hub (5) comprises, some distance from the fixed plate (3), supporting spokes (13) starting from the hub and extending as far as the internal face of the wall of the drum (2).
    6. Reel according to Claim 5, characterized in that each axially projecting element (7) starting from the fixed plate (3) lies angularly between two supporting spokes (13) and that a support bar (14), running along a chord between two supporting spokes (13) is rigidly connected to the said element (7).
    7. Reel according to one of the preceding claims, characterized in that the quick-fit connection means (F) for the removable plate (4) comprise, on the same side as the hub (5), a male central sleeve (27) equipped with a housing (29) for a key (30) parallel to the axis and, on the same side as the mobile plate (4), a female central sleeve (22) equipped with a groove (31) parallel to the axis, capable of housing the key when the female sleeve (22) is fitted over the male sleeve (27) so that the removable plate (4) is thus prevented from rotating on the hub (5), there also being means (35a, 35b, 36, 38) for the axial retention of this removable plate.
    8. Reel according to Claim 7, characterized in that the means of axial retention comprise a ring (36) fitted on the end of the hub, and a screw (38) cooperating with a tapped hole (37a, 37b) in the ring and projecting in the form of an end peg (39) into the bore of the ring (36), the male sleeve (27) of the hub comprising a groove (34a, 34b) parallel to the axis, meeting a circular arc-shaped groove (35a, 35b) to house the peg (39) by virtue of a translational displacement followed by a rotation between the ring (36) and the hub (5).
    9. Reel according to one of the preceding claims, characterized in that the wall of the drum (2) is made up of eight paddles (21) in the form of cylindrical sectors, separated by eight slots (8).
    10. Reel according to one of the preceding claims, characterized in that each end plate (3, 4) comprises tubes starting from a central sleeve and forming spokes (11, 12; 23) connected in pairs in their end region, on the outside, by trapezium-shaped panels (P), particularly ones welded to the spokes, and on the inside, by a continuous annulus (24, 25) covering the panels and the spokes.
