Abstract

The system linearly deploys a laminated steel band (8), cold-drawn, curved in its width, and having sufficient thickness for providing sufficient rigidity to the system. The steel band is rolled over multiple turns on a motorized wheel. The band is maintained on the wheel by pressure rollers (4), and is fixed to an adjustable axle (7) that is adjusted by displacement in a slot (9).

Description

La présente invention concerne un dispositif de signalisation qui autoriseThe present invention relates to a signaling device which allows

ou non l'accès à un lieu soumis à restrictions (voie routière à péage, parc de stationnement...). Les systèmes actuels de contrôle d'accès de type barrière automatique à lisse rigide présentent des inconvénients tels que:  or not access to a place subject to restrictions (toll road, parking lot ...). The current rigid barrier automatic barrier type access control systems have disadvantages such as:

leur manque de rapidité, - leur mécanique fragilisée par de fortes contraintes, principalement au niveau du réducteur, d'où un manque de fiabilité leur encombrement et leur manque de sécurité lors d'une collision avec un véhicule ou pour le personnel intervenant dans leur périmètre immédiat.  their lack of speed, - their mechanics weakened by strong constraints, mainly at the gearbox, resulting in a lack of reliability their size and their lack of safety in a collision with a vehicle or for personnel involved in their scope immediate.

- leur manque de souplesse de fonctionnement, ex. : inversion de commande en cour de fermeture ou d'ouverture - leur coût élevé, même pour des modèles peu performants Le principe consiste à déployer linéairement un ruban (8) d'acier laminé, étiré à froid et préformé curviligne dans sa largeur, et d'une épaisseur suffisante pour donner la rigidité nécessaire au système (ruban à mémoire de formes, curviligne et linéaire, qui joue le rôle d'une lisse dans une barrière classique). Le ruban est enroulé sur plusieurs tours sur une roue (5) motorisée, Deux galets de sortie (6) profilés assurent la stabilité du ruban pendant les mouvements de sortie et de rentrée. Le ruban est maintenu sur la roue support (5) par plusieurs galets presseurs (4). Les mouvements du ruban sont contrôlés par plusieurs capteurs ou cellules: - Un capteur détecte de rotation du support (1) ; il donne la mesure de la longueur de ruban déployée ainsi que la vitesse du déploiement.  - their lack of operational flexibility, ex. : inversion of control during closing or opening - their high cost, even for poorly performing models The principle consists in linearly deploying a ribbon (8) of rolled steel, cold drawn and preformed curvilinear in its width, and of sufficient thickness to give the necessary rigidity to the system (shape memory tape, curvilinear and linear, which plays the role of a smooth in a conventional barrier). The ribbon is wound on several turns on a motorized wheel (5). Two profiled output rollers (6) ensure the stability of the ribbon during the exit and re-entry movements. The tape is held on the support wheel (5) by several pressure rollers (4). The movements of the ribbon are controlled by several sensors or cells: - A sensor detects rotation of the support (1); it gives the measure of the length of ribbon deployed as well as the speed of deployment.

Groupe de plusieurs capteurs (2) qui définit une zone de freinage et indique que le ruban est en position rentrée (fin de course) Une cellule (3) qui indique que le ruban est correctement déployé et qu'aucun objet étranger ne se trouve dans sa zone de fonctionnement.  Group of several sensors (2) which defines a braking zone and indicates that the ribbon is in the retracted position (limit switch) A cell (3) which indicates that the ribbon is correctly deployed and that no foreign object is in its operating area.

^ Un capteur (10) qui indique que le ruban n'a pas été arraché (dégondage de sécurité) La sécurité, pendant le déploiement, est obtenu en fixant l'extrémité du ruban (8) à un axe (7) réglable se trouvant prêt du son point de départ. Le ruban décrit donc une courbe qui se déplace au fur et à mesure du déploiement. L'extrémité du ruban est sertie autour de l'axe (7) afin de permettre le dégondage. L'axe (7) est également réglable par déplacement dans la lumière (9) pour permettre de trouver la stabilité optimum du ruban pendant la phase de démarrage Ce dispositif permet de résoudre la majorité des problèmes causés par un système classique en effet: = il permet des coûts moindres du fait de sa simplicité - il permet d'installer des systèmes de barrières dans des parcs de hauteur de plafond 5 restreinte d'obtenir une vitesse d'ouverture et de fermeture dans un laps de temps inférieur aux systèmes utilisés actuellement la sécurité, le ruban se déformant facilement au contact d'un objet étranger ^ le système peut, dans certain cas, redémarrer de lui-même, ex.: chute du ruban: il suffit alors de rentrer le ruban à petite vitesse pour qu'il reprenne sa place.  ^ A sensor (10) which indicates that the tape has not been torn off (safety release) Safety during deployment is obtained by fixing the end of the tape (8) to an adjustable axis (7) located ready from its starting point. The ribbon thus describes a curve that moves as the deployment unfolds. The end of the tape is crimped around the axis (7) to allow the release. The axis (7) is also adjustable by displacement in the light (9) to allow to find the optimum stability of the ribbon during the startup phase This device solves most of the problems caused by a conventional system indeed: = it allows for lower costs because of its simplicity - it makes it possible to install barrier systems in low ceilings parks 5 to obtain a speed of opening and closing in a shorter period of time than the systems currently in use. safety, the tape deforming easily in contact with a foreign object ^ the system can, in some cases, restart itself, eg: fall of the ribbon: it is then enough to enter the ribbon at low speed so that it resume his place.

É il permet avec un seul équipement de gérer deux voies en accès à l'alternat cas particulier utilisé dans les gares de péage autoroutières équipées de voies de télé-péage.  E it allows with a single equipment to manage two lanes in access to the alternat particular case used in toll stations equipped with highway toll roads.

- son mécanisme plus fluide (à comparer aux contraintes mécaniques d'un système de 15 barrière classique au niveau des biellettes et du réducteur moteur) permet d'obtenir une plus grande fiabilité - il autorise une gestion électronique de type asservissement linaire, avec une maîtrise plus fine des commandes d'ouverture et de fermeture (gestion du déploiement au centimètre prêt, inversion à tout instant sans aucune difficulté).  its more fluid mechanism (to be compared to the mechanical stresses of a conventional barrier system at the rods and the motor gearbox) makes it possible to obtain greater reliability; it allows electronic management of linear servo-control type, with a degree of control; finer opening and closing commands (deployment management centimeter ready, inversion at any time without any difficulty).

Les dessins en annexe montrent le système sans motorisation elle ne fait pas partie de l'invention. Les capteurs ou cellules sont indiqués à titre indicatif Ils donnent une idée de l'électronique d'asservissement à concevoir.  The attached drawings show the system without motorization it does not form part of the invention. The sensors or cells are indicative. They give an idea of the servo electronics to be designed.

Les figures montrent également les différents organes fonctionnels de l'invention ainsi que de mode d'exploitation: mode standard de barrière classique et mode de fonctionnement à l'alternat, La pièce maîtresse est le ruban d'acier qui devra avoir toutes les caractéristiques mécaniques pour garder une mémoire de forme curviligne et linéaire. La seconde pièce est une roue pour le mode standard et un ensemble de deux galets profilés pour le mode alternat dans les deux cas ils devront épouser la forme curviligne du ruban et le maintenir dans sa position linéaire, Dans le mode standard la roue (6) devra être la plus légère possible; elle comportera sur sa face inférieure et sur sa circonférence une échelle graduée permettant une Iecture optique qui aura pour rôle de générer des tops au niveau d'un capteur optique (1) et permettre ainsi une gestion électronique de l'asservissement. Les galets presseurs (4) sont montés sur un axe qui peut se déplacer latéralement et compensé par un ressort.  The figures also show the various functional components of the invention as well as the operating mode: conventional standard barrier mode and alternating mode of operation. The centerpiece is the steel strip which must have all the mechanical characteristics. to keep a curvilinear and linear shape memory. The second piece is a wheel for the standard mode and a set of two profiled rollers for the alternating mode in both cases they will have to fit the curvilinear shape of the ribbon and keep it in its linear position, In the standard mode the wheel (6) should be as light as possible; it will comprise on its underside and on its circumference a graduated scale allowing an optical reading which will have the role of generating tops at an optical sensor (1) and thus allow electronic management of the servocontrol. The pressure rollers (4) are mounted on an axis which can move laterally and compensated by a spring.

Remarques: le ruban enroulée autour de la roue et plaqué par les galets presseur se comporte comme un ressort et a tendance à vouloir se dérouler (mémoire linéaire). 5 - La motorisation peut se faire de plusieurs manières: o Par la roue support du ruban (5) o Par l'un des galets de sortie (6) Dans le cas du mode alternat d'un système de barrière automatique qui gère deux accès, la roue support de ruban est remplacée par deux galets (Il) et (12) dont l'un est motorisé (Il) et le second (12) supportera une roue phonique lu par une cellule optique pour la gestion électronique du déploiement  Notes: The ribbon wrapped around the wheel and pressed by the pinch rollers acts as a spring and tends to unwind (linear memory). 5 - The motorization can be done in several ways: o By the ribbon support wheel (5) o By one of the output rollers (6) In the case of the alternate mode of an automatic barrier system that manages two accesses , the ribbon support wheel is replaced by two rollers (II) and (12), one of which is motorized (II) and the second (12) will support a sound wheel read by an optical cell for the electronic management of the deployment
