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.

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.
L'invention consiste, mises à part les
dispositions exposées ci-dessus, en un certain nombre
d'autres dispositions dont il sera plus explicitement
question ci-après à propos d'un exemple de réalisation
décrit avec références aux dessins ci-annexés, mais qui
n'est nullement limitatif.
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
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
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
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
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
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
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
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
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,
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
Puis on installe le deuxième flasque intermédiaire
6 comme expliqué pour le premier.Then we install the second
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
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
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
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
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.
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).
