Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne un touret connecté et un procédé d'obtention d'un touret connecté.The present invention relates to a connected drum and a method of obtaining a connected drum.

ETAT DE LA TECHNIQUESTATE OF THE ART

Un touret est un dispositif de stockage d'un câble comprenant deux joues et un tambour (aussi appelé fût) agencé entre les deux joues. Chaque joue présente une surface externe et une surface interne opposée à la surface externe. Les surfaces internes respectives des deux joues sont mutuellement en regard et délimitent un espace de stockage d'un câble enroulé autour du tambour.A drum is a device for storing a cable comprising two cheeks and a drum (also called drum) arranged between the two cheeks. Each cheek has an outer surface and an inner surface opposite to the outer surface. The respective internal surfaces of the two cheeks are mutually opposite and delimit a storage space of a cable wound around the drum.

Dans le sillage du développement de l'Internet des objets, il a été proposé d'intégrer à un touret présentant une telle structure une balise de sorte à obtenir un touret « connecté ». La balise comprend une interface de communication pour émettre des signaux transportant des données relatives au touret et/ou au câble stocké dans l'espace de stockage, sous forme de signaux radios, infrarouges, visuels ou sonores.In the wake of the development of the Internet of Things, it has been proposed to integrate a reel having such a structure a tag so as to obtain a "connected" reel. The beacon includes a communication interface for transmitting signals carrying data relating to the reel and / or the cable stored in the storage space, in the form of radio, infrared, visual or sound signals.

Il a été proposé en particulier de loger la balise dans une cavité formée dans l'une des deux joues. La cavité est borgne et débouche exclusivement dans la surface externe de la joue. Le document WO 03/057610 A1 décrit un tel touret ainsi qu'un procédé pour l'obtenir, selon les préambules des revendications 1 et 13.It has been proposed in particular to house the beacon in a cavity formed in one of the two cheeks. The cavity is one-eyed and opens exclusively into the outer surface of the cheek. The document WO 03/057610 A1 describes such a drum and a method for obtaining it, according to the preambles of claims 1 and 13.

Une telle disposition de la balise a toutefois pour inconvénient d'exposer la balise à de potentielles agressions extérieures susceptibles de l'endommager, par exemple du fait du frottement entre deux joues de deux tourets mis côte-à-côte lors de leur stockage.However, such an arrangement of the beacon has the disadvantage of exposing the beacon to potential external aggression likely to damage it, for example because of the friction between two cheeks of two reels placed side by side during their storage.

Une telle disposition a également comme conséquence d'augmenter les risques de mauvaise transmission des signaux. En effet, la surface externe d'un touret est généralement amenée à être en regard de ou être plaquée contre un autre touret, un mur ou un autre obstacle au cours de sa manutention et de son transport.Such an arrangement also has the consequence of increasing the risks of poor signal transmission. Indeed, the outer surface of a drum is generally brought to be facing or be pressed against another drum, a wall or other obstacle during its handling and transport.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

Un but de l'invention est de mieux protéger une balise d'un touret connecté contre des agressions extérieures et d'améliorer la qualité de transmission des signaux émis par une telle balise.An object of the invention is to better protect a beacon of a drum connected against external aggression and improve the quality of transmission of the signals emitted by such a beacon.

A cet effet il est proposé un touret selon la revendication indépendante 1 comprenant :

  • une joue présentant une surface interne délimitant un espace de stockage d'un câble, une cavité étant formée dans la joue,
  • une balise au moins en partie logée dans la cavité et comprenant une interface de communication pour émettre des signaux transportant des données relatives au touret et/ou au câble stocké dans l'espace de stockage,
dans lequel la cavité débouche dans la surface interne.For this purpose it is proposed a drum according to independent claim 1 comprising:
  • a cheek having an inner surface delimiting a storage space of a cable, a cavity being formed in the cheek,
  • a beacon at least partly housed in the cavity and comprising a communication interface for transmitting signals carrying data relating to the reel and / or the cable stored in the storage space,
wherein the cavity opens into the inner surface.

La cavité débouchant dans la surface interne offre la possibilité de positionner facilement cette balise vers l'espace de stockage du câble de façon à ce que cette balise ne dépasse pas de la surface externe de la joue du touret, quitte même à ce que la balise dépasse de la surface interne de la joue du touret si cette balise est trop volumineuse pour être contenue entièrement dans la cavité.The cavity opening into the internal surface offers the possibility of easily positioning this beacon towards the storage space of the cable so that this beacon does not protrude from the outer surface of the cheek of the reel, even if the beacon protrudes from the inner surface of the cheek of the reel if this beacon is too large to be contained entirely in the cavity.

De plus, le fait que la cavité débouche dans la surface interne autorise une propagation de signaux émis par la balise vers l'espace de stockage puis vers l'extérieur de la balise. Ces signaux ne sont pas perturbés par la présence d'un touret adjacent, d'un mur ou d'un autre obstacle qui serait en regard ou plaqué contre la surface externe de la joue du touret. La qualité de transmission de signaux par la balise s'en trouve donc améliorée.In addition, the fact that the cavity opens into the inner surface allows a propagation of signals emitted by the beacon to the storage space and then to the outside of the beacon. These signals are not disturbed by the presence of an adjacent drum, a wall or other obstacle that would be opposite or pressed against the outer surface of the cheek of the drum. The quality of signal transmission by the beacon is thus improved.

De préférence, le touret comprend un tambour présentant une surface d'enroulement délimitant également l'espace de stockage, et la cavité est plus proche du bord libre circonférentiel que de la surface d'enroulement. Un câble comprenant des parties métalliques et stocké dans l'espace de stockage est susceptible de former une cage de Faraday et donc de perturber la transmission signaux comportant les données émises par la balise. Un câble ne comprenant pas de parties métalliques fait quoi qu'il en soit écran vis-à-vis de la propagation des signaux. Qui plus est, la présence éventuelle d'eau dans les interstices entre plusieurs portions du câble enroulé est également un problème, car même dans le cas d'un câble diélectrique cette présence d'eau atténuera différents types de signaux. Par conséquent, positionner la balise à proximité du bord libre circonférentiel de la joue a pour effet d'éloigner la balise d'un câble stocké dans l'espace de stockage, et donc limiter l'apparition de ces perturbations après enroulement d'un câble dans l'espace de stockage.Preferably, the drum comprises a drum having a winding surface also delimiting the storage space, and the cavity is closer to the circumferential free edge than to the winding surface. A cable comprising metal parts and stored in the storage space is capable of forming a Faraday cage and thus disturbing the transmission signals comprising the data transmitted by the beacon. A cable not including any metal parts does anyhow screen vis-à-vis the propagation of signals. Moreover, the presence of water in the interstices between several portions of the coiled cable is also a problem, because even in the case of a dielectric cable this presence of water will attenuate different types of signals. Therefore, positioning the beacon near the free circumferential edge of the cheek has the effect of moving the beacon of a cable stored in the storage space, and thus limit the appearance of these disturbances after winding a cable in the storage space.

De préférence, le touret comprenant en outre un câble enroulé dans l'espace de stockage entre la surface d'enroulement et la cavité sans recouvrir la cavité. Dans une telle configuration, la qualité de transmission des signaux alors garantie, ceux-ci n'étant pas gênés par le câble enroulé.Preferably, the drum further comprising a cable wound in the storage space between the winding surface and the cavity without covering the cavity. In such a configuration, the quality of signal transmission then guaranteed, they are not hindered by the coiled cable.

Dans un premier mode de réalisation, la joue présente une surface externe opposée à la surface interne et la cavité débouche également dans la surface externe.In a first embodiment, the cheek has an outer surface opposite to the inner surface and the cavity also opens into the outer surface.

Ces caractéristiques permettent d'augmenter le volume de la cavité et donc de permettre un logement d'une balise dans une joue de touret particulièrement fine, et ce sans que la balise ne dépasse de la surface externe de la joue, et par ailleurs sans que la balise ne dépasse de la surface interne de la joue empiétant de la sorte sur l'espace de stockage du câble, ce qui risquerait de gêner l'enroulement du câble dans cet espace de stockage ou son dévidage hors de cet espace de stockage. Ceci permet également d'offrir un accès plus facile à la cavité, par exemple à des fins de maintenance.These characteristics make it possible to increase the volume of the cavity and thus to allow the housing of a beacon in a particularly thin drum lug, and this without the beacon protruding from the outer surface of the cheek, and without the beacon protruding from the inner surface of the cheek so encroaching on the storage space of the cable, which could interfere with the winding the cable in this storage space or its unwinding out of this storage space. This also makes it possible to offer easier access to the cavity, for example for maintenance purposes.

Eventuellement, la balise est positionnée par rapport à la joue pour affleurer au moins en partie la surface externe de la joue sans faire saillie à l'extérieur de la joue.Optionally, the beacon is positioned relative to the cheek for flush at least partially the outer surface of the cheek without protruding outside the cheek.

De préférence, la balise comprend une butée agencée pour venir en appui contre la surface interne de la joue, de sorte à empêcher une sortie de la balise hors de la cavité par la surface externe. Une telle butée est particulièrement efficace pour éviter une sortie intempestive de la balise qui serait de nature à l'exposer à des agressions extérieures.Preferably, the beacon comprises an abutment arranged to abut against the inner surface of the cheek, so as to prevent an exit of the beacon from the cavity by the outer surface. Such a stop is particularly effective to prevent an inadvertent exit of the beacon that would be likely to expose it to external aggression.

La butée peut présenter une surface libre de forme convexe orientée pour être en regard d'un câble stocké dans l'espace de stockage. Une butée présentant une telle surface convexe a l'avantage de préserver l'intégrité d'un câble stocké dans l'espace de stockage du touret.The stop may have a convex shaped free surface oriented to be opposite a cable stored in the storage space. An abutment having such a convex surface has the advantage of preserving the integrity of a cable stored in the reel storage space.

Dans un deuxième mode de réalisation, la cavité est une cavité borgne débouchant exclusivement dans la surface interne. Avec une telle cavité borgne, la joue elle-même constitue une barrière empêchant la balise de dépasser du touret par la surface externe de la joue, ou de sortir de manière intempestive de la joue par une telle surface externe. La protection de la balise contre des agressions extérieures est donc garantie sans qu'il soit nécessaire d'intégrer une butée à cet effet dans la balise, ce qui simplifie la fabrication de la balise.In a second embodiment, the cavity is a blind cavity opening exclusively in the inner surface. With such a blind cavity, the cheek itself is a barrier preventing the beacon from protruding from the drum by the outer surface of the cheek, or inadvertently out of the cheek by such an outer surface. The protection of the beacon against external aggression is guaranteed without the need to incorporate a stop for this purpose in the beacon, which simplifies the manufacture of the beacon.

Par ailleurs, la balise peut comprendre un boîtier contenant l'interface de communication, des moyens de fermeture étanche du boîtier, des moyens de fixation du boîtier à la joue, dans lequel les moyens de fermeture étanche et les moyens de fixation sont configurés pour que le boîtier puisse être fermé de manière étanche avant la fixation du boîtier à la joue.Moreover, the beacon may comprise a housing containing the communication interface, means for sealing the housing, means for fastening the housing to the cheek, in which the sealing means and the fixing means are configured so that the housing can be closed tightly before fixing the housing to the cheek.

Le boîtier peut comprendre une base et un couvercle, et les moyens de fermeture étanche du boîtier peuvent comprendre : au moins un élément de clipsage du couvercle à la base et un joint d'étanchéité agencé pour rendre le boîtier étanche lorsque le couvercle est clipsé à la base, ou au moins une soudure du couvercle à la base réalisée par ultrasons.The housing may comprise a base and a cover, and the sealing means of the housing may comprise: at least one clip-on element of the cover at the base and a seal arranged to make the housing watertight when the cover is clipped to the base, or at least a weld of the lid to the base made by ultrasound.

Les moyens de fixation du boîtier à la joue peuvent comprendre au moins une première paroi du boîtier et une vis soit agencée pour traverser la première paroi et pénétrer dans la joue, soit vissée dans le boîtier de sorte à solliciter la première paroi vers la joue.The fastening means of the housing to the cheek may comprise at least a first wall of the housing and a screw is arranged to pass through the first wall and penetrate into the cheek, or screwed into the housing so as to urge the first wall towards the cheek.

Dans le cas où la cavité débouche également dans la surface externe de la joue, la vis peut pénétrer dans la joue par une surface intérieure de la cavité reliant mutuellement les surfaces interne et externe de la joue.In the case where the cavity also opens into the outer surface of the cheek, the screw can penetrate into the cheek by an inner surface of the cavity interconnecting the inner and outer surfaces of the cheek.

Selon un autre aspect de l'invention, il est proposé un procédé d'obtention d'un touret connecté selon la revendication indépendante 13 à partir d'un touret comprenant une joue présentant une surface interne délimitant un espace de stockage d'un câble, et d'une balise comprenant une interface de communication pour émettre des signaux transportant des données relatives au touret et/ou à un câble stocké dans l'espace de stockage. Ce procédé comprend des étapes de formation d'une cavité dans la joue débouchant dans la surface interne, et de logement de la balise dans la cavité formée débouchant dans la surface interne.According to another aspect of the invention, there is provided a method for obtaining a connected drum according to the independent claim 13 from a drum comprising a cheek having an inner surface delimiting a storage space of a cable, and a beacon comprising a communication interface for transmitting signals carrying data relating to the reel and / or a cable stored in the repository. This method comprises steps of forming a cavity in the cheek emerging in the inner surface, and housing the beacon in the formed cavity opening into the inner surface.

DESCRIPTION DETAILLEE DE MODES DE REALISATION DE L'INVENTIONDETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

En référence aux figures 1 et 2 , un touret 1 comprend conventionnellement deux joues 2, 3 et un tambour 4 agencé entre les deux joues 2, 3.With reference to Figures 1 and 2 , a drum 1 conventionally comprises two cheeks 2, 3 and a drum 4 arranged between the two cheeks 2, 3.

Le tambour 4 est un support d'enroulement d'un câble à stocker dans le touret 1. Il présente une surface libre d'enroulement 6 s'étendant autour d'un axe central X du touret 1. Le tambour est typiquement de révolution, voire cylindrique.The drum 4 is a winding support for a cable to be stored in the drum 1. It has a free winding surface 6 extending around a central axis X of the drum 1. The drum is typically of revolution, even cylindrical.

La joue 2 présente une surface externe 8 et une surface interne 10 opposées.The cheek 2 has an outer surface 8 and an inner surface 10 opposite.

Les deux surfaces 8 et 10 opposées sont planes, en forme de couronne ou de disque.The two opposite surfaces 8 and 10 are planar, crown-shaped or disc-shaped.

La joue 2 présente par ailleurs un bord libre circonférentiel 12, par exemple de profil circulaire. Le bord libre circonférentiel 12 relie la surface interne 10 à la surface externe 8.The cheek 2 also has a circumferential free edge 12, for example of circular profile. The circumferential free edge 12 connects the inner surface 10 to the outer surface 8.

La joue 2 présente une épaisseur entre sa surface externe 8 et sa surface interne 10, mesurée parallèlement à l'axe central X, qui est comprise entre quelques millimètres, typiquement 1 ou 2 millimètres, et une centaine de millimètres.The cheek 2 has a thickness between its outer surface 8 and its inner surface 10, measured parallel to the central axis X, which is between a few millimeters, typically 1 or 2 millimeters, and a hundred millimeters.

L'autre joue 3 présente une forme identique à celle de la joue 2.The other plays 3 has a shape identical to that of the cheek 2.

Les surfaces internes respectives des deux joues 2, 3 sont mutuellement en regard et délimitent avec la surface d'enroulement 6 un espace de stockage E d'un câble enroulé autour du tambour 4 de forme annulaire.The respective internal surfaces of the two cheeks 2, 3 are mutually opposite and delimit with the winding surface 6 a storage space E of a cable wound around the drum 4 of annular shape.

Une cavité C est formée dans la joue 2. La cavité C débouche dans la surface interne 10 laquelle donne dans l'espace de stockage E.A cavity C is formed in the cheek 2. The cavity C opens into the inner surface 10 which gives into the storage space E.

Cette cavité C débouche également dans la surface externe 8 de la joue 2 : elle est donc traversante.This cavity C also opens into the outer surface 8 of the cheek 2: it is therefore through.

La cavité C forme un conduit ayant une surface 14 reliant la surface interne 10 de la joue 2 à la surface externe 8 de la joue 2. Cette surface 14 est par exemple de révolution autour d'un axe parallèle à l'axe central X du touret 1, voire cylindrique.The cavity C forms a duct having a surface 14 connecting the inner surface 10 of the cheek 2 to the outer surface 8 of the cheek 2. This surface 14 is for example of revolution about an axis parallel to the central axis X of the drum 1, or cylindrical.

De préférence, la cavité C est plus proche du bord libre circonférentiel 12 que de l'axe central. Très préférentiellement, la cavité C est plus proche du bord libre circonférentiel 12 que de la surface d'enroulement 6 du tambour 4.Preferably, the cavity C is closer to the free circumferential edge 12 than to the central axis. Very preferably, the cavity C is closer to the free circumferential edge 12 than to the winding surface 6 of the drum 4.

Les joues 2, 3 du touret 1, voire également le tambour 4, sont réalisées en bois contreplaqué ou en métal tel que du fer.The cheeks 2, 3 of the drum 1, or even the drum 4, are made of plywood or metal such as iron.

Une balise 16 est au moins en partie logée dans la cavité C de sorte à obtenir un touret 1 connecté.A beacon 16 is at least partially housed in the cavity C so as to obtain a reel 1 connected.

La balise 16 comprend un boîtier et une interface de communication de signaux, contenue dans le boîtier.The beacon 16 comprises a housing and a signal communication interface contained in the housing.

L'interface de communication est configurée pour émettre des signaux transportant des données relatives au touret 1 et/ou à un câble stocké dans l'espace de stockage E. Les signaux émis par l'interface de communication peuvent être des signaux radio, infrarouge, visuels, sonores, etc.The communication interface is configured to transmit signals carrying data relating to the reel 1 and / or to a cable stored in the storage space E. The signals emitted by the communication interface may be radio signals, infrared signals, visual, sound, etc.

Dans une application particulière, les données transmissibles par l'interface de communication comprennent des données de géolocalisation du touret 1.In a particular application, the data transmissible by the communication interface comprise geolocation data of the reel 1.

La balise 16 peut en particulier être équipée d'un premier module de localisation spécifique qui va permettre de communiquer avec, d'une part, d'autres modules de localisation du même type insérés dans des balises d'autres tourets connectés, et d'autre part avec un deuxième module de localisation intégré à un terminal d'utilisateur comprenant une caméra, un écran, et une application de réalité augmentée, permettant à un utilisateur d'un tel terminal d'assurer une localisation précise à faible distance du touret (quelques dizaines de mètres). Le terminal d'utilisateur est par exemple un smartphone, et le deuxième module de localisation est fixé par simple collage au dos du smartphone.The beacon 16 may in particular be equipped with a first specific location module which will make it possible to communicate with, on the one hand, other locator modules of the same type inserted in beacons of other connected reels, and on the other hand. secondly with a second location module integrated into a user terminal comprising a camera, a screen, and an augmented reality application, enabling a user of such a terminal to ensure a precise location at a short distance from the drum (a few tens of meters). The user terminal is for example a smartphone, and the second location module is fixed by simply sticking to the back of the smartphone.

La recherche du touret connecté 1 se fait alors par l'utilisation de l'application exécutée par le terminal qui, en première approche, guide l'utilisateur du terminal vers le touret connecté 1 en lui donnant des informations en temps réel sur la direction à prendre, et la distance par rapport au touret. Ensuite, lorsque le touret 1 est à proximité du terminal, l'application incruste dans des images acquises par la caméra et montrant le touret un marqueur supplémentaire qui désigne spécifiquement le touret connecté 1 dans ces images, avant de les afficher sur l'écran du terminal.The search for the connected drum 1 is then done by the use of the application executed by the terminal which, as a first approach, guides the user of the terminal to the connected drum 1 by giving him real time information on the direction to take, and the distance to the reel. Then, when the drum 1 is near the terminal, the application embosses in images acquired by the camera and showing the drum an additional marker which specifically refers to the connected drum 1 in these images, before displaying them on the screen of the drum. terminal.

La balise 16 peut également comprendre d'autres composants électroniques contenus dans le boîtier, par exemple au moins un des composants suivants :

  • un ou plusieurs capteurs adaptés pour acquérir des signaux porteurs de certaines des données à transmettre par l'interface de communication,
  • une mémoire mémorisant des données permettant d'identifier un type du touret et/ou un type du câble enroulé dans l'espace de stockage E,
  • une batterie pour alimenter en énergie les autres composants électroniques de la balise 16, notamment l'interface de communication.
The beacon 16 may also comprise other electronic components contained in the housing, for example at least one of the following components:
  • one or more sensors adapted to acquire signals carrying some of the data to be transmitted by the communication interface,
  • a memory storing data making it possible to identify a type of reel and / or a type of cable wound in the storage space E,
  • a battery for supplying power to the other electronic components of the beacon 16, in particular the communication interface.

En référence à la figure 3 , le boîtier comprend une base 18 et un couvercle 20.With reference to the figure 3 The housing comprises a base 18 and a cover 20.

La base 18 présente une paroi de fond 22 et une paroi latérale 24, ces parois définissant un logement pour recevoir les composants électroniques de la balise 16 dont l'interface de communication notamment.The base 18 has a bottom wall 22 and a side wall 24, these walls defining a housing for receiving the electronic components of the beacon 16 including the communication interface in particular.

La base 18 présente une forme de révolution autour d'un axe de la balise 16.The base 18 has a shape of revolution around an axis of the beacon 16.

Le rayon externe de la paroi latérale 24 est sensiblement égal au rayon de la surface 14 définissant la cavité C dans la joue 2.The outer radius of the side wall 24 is substantially equal to the radius of the surface 14 defining the cavity C in the cheek 2.

La paroi de fond 22 comprend une collerette 26 ayant un rayon externe plus grand que le rayon externe de la paroi latérale 24. La collerette 26 forme une butée destinée à venir en contact avec la surface interne 10 de la joue 2.The bottom wall 22 comprises a collar 26 having an outer radius greater than the outer radius of the side wall 24. The collar 26 forms a stop intended to come into contact with the inner surface 10 of the cheek 2.

La collerette 26 présente une surface libre 28 de forme convexe. Cette surface libre est orientée pour être en regard d'un câble stocké dans l'espace de stockage E, lorsque la balise 16 est reçue dans la cavité C.The collar 26 has a free surface 28 of convex shape. This free surface is oriented to be opposite a cable stored in the storage space E, when the beacon 16 is received in the cavity C.

Par ailleurs, la paroi latérale 24 présente une surface interne 30 donnant à l'intérieur du boîtier et une surface externe 32 donnant à l'extérieur du boîtier. La surface externe 8 est cylindrique de révolution autour du même axe que la base 18.On the other hand, the sidewall 24 has an inner surface 30 giving inside the housing and an outer surface 32 to the outside of the housing. The outer surface 8 is cylindrical in revolution about the same axis as the base 18.

La balise 16 comprend des moyens de fixation du boîtier au touret 1. Ces moyens de fixation comprennent une pluralité de vis 34, 36 (ici deux) et une pluralité de passages correspondants 38, 40, chaque passage présentant un orifice interne débouchant dans la surface interne 30 et un orifice externe débouchant dans la surface externe 32 de la paroi latérale 24.The tag 16 comprises means for fixing the casing to the drum 1. These fixing means comprise a plurality of screws 34, 36 (here two) and a plurality of corresponding passages 38, 40, each passage having an internal orifice opening into the surface. internal 30 and an external opening opening into the outer surface 32 of the side wall 24.

Les vis 34, 36 présentent chacune un filetage externe adapté pour coopérer avec les passages 38, 40. Chaque vis 34, 36 présente un trou borgne de forme hexagonale destiné à recevoir l'extrémité d'un outil de forme complémentaire afin de la mettre en rotation, et donc la visser.The screws 34, 36 each have an external thread adapted to cooperate with the passages 38, 40. Each screw 34, 36 has a hexagonal shaped blind hole intended to receive the end of a tool of complementary shape in order to put it into shape. rotation, and thus screw it.

Les passages 38, 40 présentent chacun un filetage interne adapté pour coopérer avec une des vis 34, 36.The passages 38, 40 each have an internal thread adapted to cooperate with one of the screws 34, 36.

Chaque passage 38, 40 est orienté pour qu'une vis 34, 36 traversant le passage puisse pénétrer par ailleurs dans la surface 14 de la joue 2 reliant la surface interne 10 de la joue 2 à la surface externe 8 de la joue 2, lorsque la balise 16 est logée dans la cavité C formée dans la joue 2.Each passage 38, 40 is oriented so that a screw 34, 36 passing through the passage can also penetrate into the surface 14 of the cheek 2 connecting the inner surface 10 of the cheek 2 to the outer surface 8 of the cheek 2, when the beacon 16 is housed in the cavity C formed in the cheek 2.

De préférence, l'orientation des passages 38, 40 est adaptée pour que l'axe de vissage de chaque vis 34, 36 soit orienté compris entre 0 et 90 degrés par rapport à l'axe de révolution de la base 18, par exemple à 45 degrés.Preferably, the orientation of the passages 38, 40 is adapted so that the screw axis of each screw 34, 36 is oriented between 0 and 90 degrees relative to the axis of revolution of the base 18, for example to 45 degrees.

La paroi latérale 24 comporte de préférence deux parties 42, 44 faisant saillie vers l'intérieur de la base 18, les passages 38, 40 étant formés respectivement dans ces parties 42, 44.The side wall 24 preferably has two inwardly projecting portions 42, 44 of the base 18, the passages 38, 40 being formed respectively in these portions 42, 44.

Les deux parties 42, 44 sont reliées également à la paroi de fond 22, et présentent chacun un sommet dans lequel est ménagé l'orifice interne des passages 38, 40.The two parts 42, 44 are also connected to the bottom wall 22, and each have a top in which is formed the internal orifice of the passages 38, 40.

Par ailleurs, le couvercle 20 présente une forme générale de disque dont le rayon extérieur est sensiblement égal au rayon intérieur de la paroi latérale 24 de la base 18.Furthermore, the cover 20 has a general disc shape whose outer radius is substantially equal to the inner radius of the side wall 24 of the base 18.

Plusieurs orifices traversants 46, 48 sont ménagés dans le couvercle 20. Ces orifices 46, 48 sont positionnés de sorte à être en regard des passages 38, 40 ménagés dans la base 18, lorsque le couvercle 20 est rapporté sur la base 18. Ainsi, les vis 34, 36 peuvent être insérées dans les passages 38, 40 via les orifices 46, 48 ménagés dans le couvercle 20, même après fermeture du boîtier au moyen du couvercle 20.Several through orifices 46, 48 are formed in the cover 20. These orifices 46, 48 are positioned so as to face the passages 38, 40 formed in the base 18, when the cover 20 is attached to the base 18. Thus, the screws 34, 36 can be inserted into the passages 38, 40 via the orifices 46, 48 formed in the cover 20, even after closing the housing by means of the cover 20.

Par ailleurs, le diamètre des orifices traversants 46, 48 est plus grand que le diamètre de chaque vis 34, 36. De la sorte, le couvercle 20 peut être éloigné de la base 18 même si les vis 36, 36 ont été passées à travers les passages 38, 40 de la base 18.Moreover, the diameter of the through holes 46, 48 is greater than the diameter of each screw 34, 36. In this way, the cover 20 can be moved away from the base 18 even if the screws 36, 36 have been passed through. passages 38, 40 of the base 18.

La balise 16 comprend par ailleurs des moyens de fermeture étanche du boîtier. Ces moyens de fermeture comprennent des moyens de clipsage du couvercle 20 à la base 18 et un joint d'étanchéité 50.The tag 16 further comprises means for sealing the housing. These closing means comprise means for clipping the cover 20 to the base 18 and a seal 50.

Le joint d'étanchéité 50 comprend une forme globalement annulaire. Il est fixé à la surface interne 30 de la paroi latérale 24 de la base 18 et aux sommets des parties 42, 44.The seal 50 comprises a generally annular shape. It is attached to the inner surface 30 of the side wall 24 of the base 18 and to the vertices of the parts 42, 44.

Deux trous sont formés dans le joint d'étanchéité 50 de sorte que les passages 38, 40 puissent être accessibles depuis l'intérieur de la base 18 même après fixation du joint d'étanchéité 50 à la base 18.Two holes are formed in the seal 50 so that the passages 38, 40 can be accessible from inside the base 18 even after fixing the seal 50 to the base 18.

Les moyens de clipsage comprennent par exemple des pattes 52, 54, 56 formées sur le pourtour du couvercle 20, et des évidements correspondants débouchant dans la surface interne 30 de la paroi latérale 24 de la base 18 dans lesquels les pattes 52, 54, 56 sont reçues lorsque le couvercle 20 est posé contre le joint d'étanchéité 50.The clipping means comprise, for example, lugs 52, 54, 56 formed around the periphery of the cover 20, and corresponding recesses opening into the internal surface 30 of the side wall 24 of the base 18 in which the lugs 52, 54, 56 are received when the cover 20 is placed against the seal 50.

Dans une variante de réalisation non illustrée, les moyens de fermeture étanches comprennent au moins un cordon de soudure du couvercle 20 à la base 18 appliqué par la mise en œuvre d'un procédé de soudure par ultrasons connu de l'état de la technique. Dans ce cas, le boîtier est de préférence dans un matériau fusible (thermoplastique). Il n'est plus nécessaire dans ce cas de recourir au joint d'étanchéité 50. Toutefois, dans cette variante, la balise 16 ne peut plus être ouverte sans être endommagée, ce qui en fait un produit à usage unique.In an alternative embodiment not illustrated, the sealed closure means comprise at least one weld seam of the cover 20 to the base 18 applied by the implementation of an ultrasonic welding process known from the state of the art. In this case, the housing is preferably in a fusible material (thermoplastic). It is no longer necessary in this case to use the seal 50. However, in this variant, the tag 16 can not be opened without being damaged, which makes it a disposable product.

Les différentes pièces du touret 1 connecté sont assemblées de la manière suivante.The various parts of the connected drum 1 are assembled in the following manner.

Dans une première étape, l'interface de communication, et les autres composants électroniques de la balise 16 mentionnés précédemment sont logés dans le logement défini dans la base 18.In a first step, the communication interface and the other electronic components of the beacon 16 previously mentioned are housed in the housing defined in the base 18.

Dans une deuxième étape, le couvercle 20 est rapproché de la base 18 de sorte à reposer sur toute sa circonférence sur le joint d'étanchéité 50. Au cours de ce rapprochement, les pattes sont légèrement fléchies puis s'insèrent, par retour élastique, dans les évidements ménagés dans la paroi latérale 24 de la base 18. Le boîtier de la balise 16 est alors fermé de manière étanche, comme illustré en figure 4 . In a second step, the cover 20 is brought closer to the base 18 so as to rest on its entire circumference on the seal 50. During this approach, the tabs are slightly bent and then fit, by springback, in the recesses formed in the side wall 24 of the base 18. The housing of the beacon 16 is then sealed, as illustrated in FIG. figure 4 .

Par ailleurs, les deux vis 34, 36 sont passées à travers les deux orifices 46, 48 ménagés dans le couvercle 20, de sorte qu'elles pénètrent dans les passages 38, 40 ménagés dans la base 18, sans toutefois ressortir de la base 18 via les orifices externes des passages 38, 40.Moreover, the two screws 34, 36 are passed through the two orifices 46, 48 formed in the cover 20, so that they penetrate the passages 38, 40 formed in the base 18, without however leaving the base 18 via the external openings of the passages 38, 40.

Dans une troisième étape, la balise 16 fermée est insérée dans la cavité C. La balise 16 est insérée plus précisément dans la cavité C par la surface interne 10 de la joue, en commençant par le couvercle 20 (comme cela est indiqué par la flèche montrée en figure 2), et jusqu'à ce que la collerette 26 vienne en appui contre la surface interne 10 de la joue 2.In a third step, the closed beacon 16 is inserted into the cavity C. The beacon 16 is inserted more precisely into the cavity C by the inner surface 10 of the cheek, starting with the lid 20 (as indicated by the arrow shown in figure 2 ), and until the collar 26 bears against the inner surface 10 of the cheek 2.

Dans cette position, la balise (et plus précisément le couvercle 20) est accessible depuis la surface externe 8 du touret 1 puisque la cavité C formée dans la joue 2 est traversante.In this position, the beacon (and more precisely the cover 20) is accessible from the outer surface 8 of the drum 1 since the cavity C formed in the cheek 2 is through.

Dans cette même position, le boitier (notamment le couvercle 20) affleure au moins en partie la surface externe 8 de la joue 2.In this same position, the housing (in particular the cover 20) is at least partially flush with the outer surface 8 of the cheek 2.

Dans une quatrième étape, les deux vis 34, 36 sont vissées de sorte qu'elles ressortent hors du boîtier de la balise 16 par la paroi latérale 24 puis pénètrent dans la surface 14 de la joue 2, ce qui permet de fixer la balise 16 à la joue 2.In a fourth step, the two screws 34, 36 are screwed so that they emerge out of the beacon housing 16 by the side wall 24 and then penetrate the surface 14 of the cheek 2, which allows to fix the beacon 16 on the cheek 2.

En variante, les vis 34 et 36 sont passées à travers les deux orifices 46, 48 ménagés dans le couvercle 20 après l'insertion de la balise 16 dans la cavité C.Alternatively, the screws 34 and 36 are passed through the two orifices 46, 48 formed in the cover 20 after the insertion of the beacon 16 into the cavity C.

L'installation de la balise 16 dans le touret 1 est alors terminée. On a ainsi obtenu un touret 1 connecté.The installation of the beacon 16 in the reel 1 is then complete. There was thus obtained a connected drum 1.

Ultérieurement, un câble peut être enroulé autour du tambour 4 dans l'espace de stockage E. La balise 16 demeure relativement éloignée d'un tel câble dans la mesure où la cavité C est à proximité du bord libre circonférentiel 12 de la joue 2.Subsequently, a cable may be wound around the drum 4 in the storage space E. The beacon 16 remains relatively far from such a cable insofar as the cavity C is close to the free circumferential edge 12 of the cheek 2.

L'interface de communication de la balise 16 émet des données relatives au touret 1 et/ou au câble enroulé dans l'espace de stockage E. Par exemple, l'une de ces données permet de géolocaliser le touret 1.The communication interface of the beacon 16 transmits data relating to the reel 1 and / or the cable wound in the storage space E. For example, one of these data makes it possible to geolocate the reel 1.

On a représenté en figure 5 un deuxième mode de réalisation de la balise 16.We have shown in figure 5 a second embodiment of the beacon 16.

Cette balise 16 diffère de la balise selon le premier mode de réalisation par le fait que les moyens de fermeture étanche et les moyens de fixation du boîtier à la joue 2 sont configurés de sorte que le boîtier ne puisse être refermé qu'après l'avoir fixé à la joue 2.This beacon 16 differs from the beacon according to the first embodiment in that the sealing means and the fastening means of the casing to the cheek 2 are configured so that the casing can be closed again after having attached to the cheek 2.

Dans ce mode de réalisation, les moyens de fermeture du boîtier ne comprennent pas de moyens de clipsage 52, 54, 56, mais comprennent des vis 60, 62, 64 distinctes des vis 34, 36 destinées à être insérées dans les passages 38, 40 de la base 18. On trouve ainsi deux types de vis dans la balise 16 : des vis de fixation 34, 36 du boîtier à la joue 2, comme dans le premier mode de réalisation, et des vis 60, 62, 64 de fermeture étanche du boîtier.In this embodiment, the closing means of the housing do not include clipping means 52, 54, 56, but comprise screws 60, 62, 64 separate screws 34, 36 intended to be inserted into the passages 38, 40. of the base 18. There are thus two types of screws in the beacon 16: fastening screws 34, 36 of the casing to the cheek 2, as in the first embodiment, and screws 60, 62, 64 for sealing of the case.

Les vis de fermeture 60, 62, 64 présentent une portion filetée et une tête de diamètre plus large que celui de la portion filetée.The closure screws 60, 62, 64 have a threaded portion and a head of larger diameter than that of the threaded portion.

La base 18 comprend des passages supplémentaires 66, 68, 70 destinés à recevoir et coopérer avec les vis de fermeture 60, 62, 64. Ces passages supplémentaires 66, 68, 70 ne débouchent pas à l'extérieur du boitier, mais uniquement à l'intérieur du boîtier. De plus, ils présentent un axe d'insertion de vis parallèle à l'axe de référence Y du boîtier.The base 18 includes additional passages 66, 68, 70 for receiving and cooperating with the closing screws 60, 62, 64. These additional passages 66, 68, 70 do not open out of the box, but only to the outside. inside the case. In addition, they have a screw insertion axis parallel to the reference axis Y of the housing.

Par ailleurs, les orifices 46, 48 et 49 ménagés dans le couvercle 20 (ici au nombre de trois) sont destinés à recevoir les vis de fermeture du boîtier et à être alignés avec les passages supplémentaires formés dans la base 18. Ces orifices 46, 48 49 présentent par ailleurs un diamètre adapté pour permettre aux vis de fermeture 60, 62, 64 de retenir le couvercle 20 contre le joint d'étanchéité 50 lorsque ces vis de fermetures sont vissées dans les passages supplémentaires de la base 18.Furthermore, the orifices 46, 48 and 49 formed in the cover 20 (here three in number) are intended to receive the closure screws of the housing and to be aligned with the additional passages formed in the base 18. These orifices 46, 48 49 present by Moreover a diameter adapted to allow the closing screws 60, 62, 64 to retain the cover 20 against the seal 50 when these closure screws are screwed into the additional passages of the base 18.

Les différentes pièces d'un touret 1 connecté embarquant une balise 16 selon le deuxième mode de réalisation sont assemblées de la manière suivante.The various parts of a connected drum 1 embodying a tag 16 according to the second embodiment are assembled in the following manner.

Dans une première étape, l'interface de communication, et les autres composants électroniques de la balise 16 mentionnés précédemment sont logés dans le logement défini dans la base 18.In a first step, the communication interface and the other electronic components of the beacon 16 previously mentioned are housed in the housing defined in the base 18.

Par ailleurs, les deux vis de fixation 34, 36 sont passées à travers les deux orifices 46, 48 ménagés dans le couvercle 20, de sorte qu'elles pénètrent dans les passages 38, 40 ménagés dans la base 18, sans toutefois ressortir de la base 18 via les orifices externes des passages 38, 40.Moreover, the two fastening screws 34, 36 are passed through the two orifices 46, 48 formed in the cover 20, so that they penetrate the passages 38, 40 formed in the base 18, without however coming out of the base 18 via the external openings of the passages 38, 40.

Dans une deuxième étape, la base 18 de la balise 16 selon le deuxième mode de réalisation est seule insérée dans la cavité C, de la même manière que pour le premier mode de réalisation.In a second step, the base 18 of the beacon 16 according to the second embodiment is only inserted in the cavity C, in the same way as for the first embodiment.

Dans une troisième étape, une fois que la collerette 26 est en butée contre la surface interne 10 de la joue, les vis de fixation 34, 36 sont vissées dans la joue 2 de la même manière que dans le premier mode de réalisation, à ceci près que le couvercle 20 n'a pas encore été rapporté sur la base 18 pour fermer le boîtier.In a third step, once the collar 26 abuts against the inner surface 10 of the cheek, the fixing screws 34, 36 are screwed into the cheek 2 in the same manner as in the first embodiment, at this point. near that the lid 20 has not yet been attached to the base 18 to close the housing.

Dans une quatrième étape, le couvercle 20 est posé contre le joint d'étanchéité 50 de sorte que les orifices 46, 48, 49 ménagés dans le couvercle 20 soient alignés avec les passages supplémentaires 66, 68, 70 formés dans la base 18. Les vis de fermeture 60, 62, 64 sont insérées dans ces orifices 46, 48, 49 puis les passages supplémentaires 66, 68, 70, de sorte à fermer le boîtier de la balise 16.In a fourth step, the cover 20 is placed against the seal 50 so that the orifices 46, 48, 49 formed in the cover 20 are aligned with the additional passages 66, 68, 70 formed in the base 18. closing screws 60, 62, 64 are inserted into these orifices 46, 48, 49 and the additional passages 66, 68, 70, so as to close the housing of the beacon 16.

On a représenté en figures 6 et 7 un troisième mode de réalisation de la balise 16.We have shown in Figures 6 and 7 a third embodiment of the beacon 16.

Cette balise 16 diffère du premier mode de réalisation par des moyens de fixation de la balise 16 à la joue 2 qui sont de forme différente.This beacon 16 differs from the first embodiment by means of fixing the beacon 16 to the cheek 2 which are of different shape.

Ces moyens de fixation comprennent deux languettes 72 formées dans la paroi latérale 24 de la base 18 (seule l'une des deux languettes est visible sur la figure 6). Chaque languette 72 est agencée pour être sollicitée vers l'extérieur de la balise lorsqu'une vis de fixation est insérée dans un passage correspondant, de sorte que les languettes 72 viennent en appui contre la surface 14 de joue 2 lorsque la balise 16 a été insérée dans la cavité C de la joue, et ainsi maintenir la balise 16 fixe par rapport à la joue 2.These fixing means comprise two tabs 72 formed in the side wall 24 of the base 18 (only one of the two tabs is visible on the figure 6 ). Each tongue 72 is arranged to be urged towards the outside of the beacon when a fixing screw is inserted in a corresponding passage, so that the tongues 72 bear against the cheek surface 2 when the beacon 16 has been inserted in the cavity C of the cheek, and thus maintain the beacon 16 fixed relative to the cheek 2.

Dans un quatrième mode de réalisation de balise 16 non illustré, les moyens de fermeture du boîtier peuvent revêtir d'autres formes (par exemple, des pas de vis sur le sur le couvercle 20 et la base 18 pour permettre un vissage du couvercle 20 sur la base 18).In a fourth embodiment of beacon 16 not shown, the closing means of the housing can take other forms (for example, screw threads on the cover 20 and the base 18 to allow screwing of the cover 20 on the base 18).

L'invention ne se limite pas aux seuls modes de réalisations décrits ci-dessus.The invention is not limited to the embodiments described above.

Plusieurs balises 16 peuvent être assemblées avec un même touret 1, que ce soit sur la même joue 2 ou bien sur les deux joues 2, 3 du touret 1.Several tags 16 can be assembled with the same drum 1, either on the same cheek 2 or on both cheeks 2, 3 of the drum 1.

Les joues 2, 3 peuvent par ailleurs présenter des surfaces interne et externe 8, 10 non planes. Par exemple, un touret métallique (fer) peut comprendre une surface externe 8 de joue 2 qui présente une pluralité de dégagements radiaux et un anneau circonférentiel dans lequel le bord libre est défini. Le touret métallique peut toucher un touret voisin par son anneau circonférentiel. Une joue 2 d'un tel touret métallique est généralement très fine. La cavité C est alors traversante, et ménagée dans l'un des dégagements radiaux. La balise 16 peut faire saillie dans un de ces dégagements radiaux, mais sans toutefois aller au-delà de de l'anneau circonférentiel, suivant une direction parallèle à l'axe X. De cette manière, la balise ne touche pas un touret voisin qui serait en contact avec cet anneau.The cheeks 2, 3 may furthermore have inner and outer surfaces 8, 10 which are not flat. For example, a metal drum (iron) may comprise an outer surface 8 of cheek 2 which has a plurality of radial clearances and a circumferential ring in which the free edge is defined. The metal drum can touch a neighboring drum by its circumferential ring. A cheek 2 of such a metal drum is generally very fine. The cavity C is then through, and formed in one of the radial clearances. The beacon 16 can protrude into one of these radial clearances, but without however going beyond the circumferential ring, in a direction parallel to the axis X. In this way, the beacon does not touch a neighboring reel which would be in contact with this ring.

Dans d'autres modes de réalisation, la cavité C dans laquelle la balise 16 est reçue est borgne, c'est-à-dire débouche exclusivement dans la surface interne 10. Une partie de la joue 2 forme ainsi une barrière être la balise 16 et la surface externe 8 de la joue. Dans ce cas, il peut être prévu que la balise 16 ne comprenne pas de collerette 26.In other embodiments, the cavity C in which the beacon 16 is received is blind, that is to say opens exclusively into the inner surface 10. Part of the cheek 2 thus forms a barrier to be the beacon 16 and the outer surface 8 of the cheek. In this case, it can be expected that the beacon 16 does not include a collar 26.
