L'inhibition de la barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 est un moyen important d'identifier les marchandises par rapport au personnel.<\/span><\/p>

Comment y parvient-il ?<\/span><\/p>

Il existe trois m\u00e9thodes : l'inhibition de type X (crois\u00e9e) avec 2 cellules photo\u00e9lectriques, l'inhibition de type L avec 2 cellules photo\u00e9lectriques et l'inhibition s\u00e9quentielle en mode T avec 4 cellules.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

L'inhibition est une fonction qui suspend temporairement le fonctionnement protecteur d'une barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9. C'est comme si vous mettiez votre t\u00e9l\u00e9phone en mode \u201cNe pas d\u00e9ranger\u201d : les appels entrants sont ignor\u00e9s pendant une courte p\u00e9riode, mais le t\u00e9l\u00e9phone reste enti\u00e8rement fonctionnel.<\/span><\/p>

Pour ce faire, il utilise des capteurs d'inhibition externes pour faire la distinction entre les mat\u00e9riaux et le personnel. Cela permet aux marchandises d'entrer et de sortir librement de la zone dangereuse prot\u00e9g\u00e9e, tout en garantissant que si quelqu'un tente d'y p\u00e9n\u00e9trer, la machine s'arr\u00eatera imm\u00e9diatement de fonctionner, \u00e9vitant ainsi toute blessure.<\/span><\/p>

Dans les sections suivantes, nous expliquerons en d\u00e9tail les trois m\u00e9thodes de muting mentionn\u00e9es ci-dessus.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Le mode de type X permet de transporter des marchandises de la zone s\u00fbre vers la zone dangereuse, tout en interdisant au personnel de p\u00e9n\u00e9trer dans la zone dangereuse \u00e0 partir de la zone s\u00fbre.<\/span><\/p>

Le nom vient de la disposition des deux capteurs photo\u00e9lectriques d'inhibition : leurs faisceaux lumineux \u00e9mis et re\u00e7us se croisent, formant un \u201cX\u201d, comme l'illustre l'image ci-dessus.<\/span><\/p>

Une condition essentielle de cette configuration est que le point d'intersection des deux faisceaux lumineux doit \u00eatre situ\u00e9 \u00e0 l'int\u00e9rieur de la zone dangereuse.<\/span><\/p>

Cette disposition sp\u00e9cifique des passages \u00e0 niveau fait qu'il est extr\u00eamement difficile pour une personne de bloquer accidentellement ou intentionnellement les deux faisceaux de capteurs en m\u00eame temps. En emp\u00eachant ce sc\u00e9nario de double blocage, le syst\u00e8me \u00e9vite les erreurs logiques et garantit que les fonctions de s\u00e9curit\u00e9 ne sont pas contourn\u00e9es involontairement.<\/span><\/p>

Par exemple, dans la pratique, nous pouvons transporter en douceur des mat\u00e9riaux de la zone de s\u00e9curit\u00e9 \u00e0 la machine sur le tapis roulant sans d\u00e9clencher l'arr\u00eat de la machine. Parall\u00e8lement, la logique (voir le tableau ci-dessous) est con\u00e7ue de mani\u00e8re \u00e0 ce que, si quelqu'un tente d'entrer, le syst\u00e8me d\u00e9tecte de mani\u00e8re fiable l'intrusion et arr\u00eate imm\u00e9diatement l'appareil pour garantir la s\u00e9curit\u00e9.<\/span><\/p>

Lors de l'installation de barri\u00e8res immat\u00e9rielles de s\u00e9curit\u00e9 et de capteurs d'inhibition, il convient de respecter les 4 points suivants :<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  1. Selon le <\/span>ISO 13855<\/span><\/a><\/span>, La hauteur d'installation de l'axe optique le plus bas d'une barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 doit \u00eatre inf\u00e9rieure \u00e0 300 mm ; si elle est sup\u00e9rieure \u00e0 cette hauteur, des personnes peuvent grimper \u00e0 l'int\u00e9rieur, ce qui peut entra\u00eener des blessures.<\/span><\/li>
  2. La hauteur minimale d'installation des cellules photo\u00e9lectriques d'inhibition doit \u00eatre sup\u00e9rieure \u00e0 l'axe optique le plus bas.<\/span><\/li>
  3. Lorsque des marchandises traversent la barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9, la distance entre les marchandises et le bord de la grille immat\u00e9rielle de s\u00e9curit\u00e9 doit \u00eatre inf\u00e9rieure \u00e0 180 mm ; dans le cas contraire, le personnel peut traverser la barri\u00e8re avec les marchandises, ce qui constitue un danger.<\/span><\/li>
  4. L'intersection des faisceaux de deux jeux de cellules photo\u00e9lectriques d'inhibition doit se trouver dans la zone de danger.<\/span><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Au contraire, le mode d'inhibition de type L est con\u00e7u pour permettre aux marchandises de se d\u00e9placer des zones dangereuses vers les zones s\u00fbres, tout en emp\u00eachant les objets ou les personnes de se d\u00e9placer des zones s\u00fbres vers les zones dangereuses.<\/span><\/p>

    Voyons comment il identifie les biens et le personnel.<\/span><\/p>

    Il s'appuie principalement sur deux capteurs photo\u00e9lectriques d'inhibition install\u00e9s dans la zone dangereuse. Sa logique est la suivante :<\/span><\/p>

    1. Si la s\u00e9quence d'entr\u00e9e est : Inhibition de la cellule photo\u00e9lectrique A(<\/span>Ce capteur est plus \u00e9loign\u00e9 du rideau lumineux de s\u00e9curit\u00e9)<\/span> ->Interruption de la cellule photo\u00e9lectrique B(<\/span>Ce capteur est le plus proche du rideau lumineux de s\u00e9curit\u00e9)<\/span>-> barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9, l'automate peut \u00eatre programm\u00e9 et d\u00e9terminer que l'entr\u00e9e se fait d'une zone dangereuse vers une zone s\u00fbre, c'est-\u00e0-dire une entr\u00e9e de marchandises. Par cons\u00e9quent, la barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 sera mise en mode d'inhibition et d\u00e9sactiv\u00e9e. Il est important de noter que lorsque le capteur B est bloqu\u00e9, le temps d'inhibition commence \u00e0 d\u00e9compter. Le temps d'inhibition doit correspondre \u00e0 l'heure de sortie des marchandises et ne doit pas \u00eatre trop long.<\/span><\/li>
    2. Si la s\u00e9quence est invers\u00e9e, c'est-\u00e0-dire rideau lumineux de s\u00e9curit\u00e9 ->capteur photo\u00e9lectrique d'inhibition, l'automate peut \u00eatre programm\u00e9 et d\u00e9terminer que l'entr\u00e9e est une entr\u00e9e pour le personnel. Par cons\u00e9quent, l'API d\u00e9clenchera une sortie et arr\u00eatera imm\u00e9diatement le fonctionnement de la machine d\u00e8s que la lumi\u00e8re de la barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9 sera bloqu\u00e9e.<\/span><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      Ce mode d'inhibition utilise quatre capteurs photo\u00e9lectriques pour \u00e9tablir une s\u00e9quence d'entr\u00e9e\/sortie stricte, ce qui permet au syst\u00e8me de faire une distinction fiable entre le personnel et les marchandises.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      Ce mode d'inhibition est con\u00e7u pour maintenir la productivit\u00e9 en permettant aux marchandises d'entrer et de sortir sans d\u00e9clencher l'arr\u00eat de la machine, tout en garantissant que toute personne tentant de p\u00e9n\u00e9trer dans une zone dangereuse est imm\u00e9diatement d\u00e9tect\u00e9e et que la machine peut \u00eatre arr\u00eat\u00e9e en toute s\u00e9curit\u00e9.<\/span><\/p>

      Comme le montre le sch\u00e9ma ci-dessus, deux capteurs d'inhibition A et B sont par exemple install\u00e9s sur le c\u00f4t\u00e9 gauche de la barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9, tandis que deux autres capteurs d'inhibition C et D sont install\u00e9s de l'autre c\u00f4t\u00e9 de la barri\u00e8re immat\u00e9rielle de s\u00e9curit\u00e9.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      Il convient de noter que la taille des marchandises doit \u00eatre sup\u00e9rieure \u00e0 la distance entre le capteur d'inhibition A et le capteur d'inhibition B, ainsi qu'entre le capteur C et le capteur D.<\/span><\/p>

      La logique devrait donc \u00eatre la suivante :<\/span><\/p>

      1. A->AB->B->rideau lumineux de s\u00e9curit\u00e9, la fonction d'inhibition est activ\u00e9e,<\/span><\/li>

          En r\u00e9sum\u00e9, l'inhibition de type X (crois\u00e9e) pour les barri\u00e8res immat\u00e9rielles de s\u00e9curit\u00e9 est utilis\u00e9e lorsque des marchandises passent d'une zone s\u00fbre \u00e0 une zone dangereuse, tout en emp\u00eachant le personnel d'y p\u00e9n\u00e9trer.<\/span><\/p>

          L'inhibition de type L est utilis\u00e9e dans le sens inverse, c'est-\u00e0-dire lorsque des marchandises passent d'une zone dangereuse \u00e0 une zone s\u00fbre.<\/span><\/p>

          L'inhibition de type T prend en charge les mouvements dans les deux sens, ce qui permet aux marchandises d'entrer dans la zone dangereuse ou d'en sortir.<\/span><\/p>

          Les trois m\u00e9thodes d'inhibition permettent de distinguer efficacement les marchandises et le personnel et garantissent une protection fiable de l'op\u00e9rateur.<\/span><\/p>
