Definitions

  • the present invention refers to an automatic limit switch device for geared motors installed in the central axis of roller doors, which entails a series of relevant and advantageous features against which They are currently used for the same purpose.
  • Its purpose is to automatically regulate the location of the microswitches for the control of raising and lowering the roller doors, being driven by the reduction motor of the door itself.
  • the end-of-stroke device that constitutes the object of the invention, is integrated by a "U" support in which three rods, a threaded center, are laid longitudinally. and which defines the spindle to move a drive piece in the thread and with functions of the nut that complements this nut-screw device; and two other parallel and lateral rods that are affected by an annular striatum.
  • the spindle has a support on the outside of the "U” support, a pinion through which it receives movement from the geared motor that drives the roller door.
  • the respective limit switches are guided, which are actuated by the corresponding pin provided in; the drive piece or nut of the device inherent to the spindle.
  • Each of these limit switches is provided with its corresponding micro-suppressor and a tilting piece that will be in charge of setting the end of ca It runs at the desired location, so that both limit switches are axially separated at the distance corresponding to the travel of the roller door, measured by the stroke made by the drive piece of the spindle-nut device.
  • the drag piece and both ends of the race are initially aligned in the direction perpendicular to the respective guide bars, these three elements being also joined by an easily removable strip.
  • this strip is removed and then the motor is started to cause the door to lift.
  • the limit switch that commands the stop is not dragged - in the door closing situation, only the other limit switch moving until the engine stops when the desired position for lifting the door is reached.
  • Immobility of the limit switches is achieved by means of a brake pin that is driven into the groove of the respective rod in which it is guided during installation.

Abstract

Le dispositif de fin de course automatique pour motoréducteurs montés sur l'axe central de portes enroulables concerne un dispositif qui offre toute une série de caractéristiques améliorées par rapport au dispositif utilisé actuellement à cette fin. Il a pour objet de réguler automatiquement l'emplacement les microrupteurs afin de commander la montée et la descente de portes enroulables lorsqu'elles sont actionnées par le motoréducteur de la porte qui lui est associée. D'une manière générale, il comprend un support (1) en 'U' où s'étendent longitudinalement trois barres, une barre centrale filetée (2) représentant la broche permettant de déplacer une pièce d'entraînement qui est vissée sur cette broche et avec fonction d'écrou qui complète ce dispositif vis-écrou, et les deux autres barres parallèles et latérales (6 et 7) qui présentent un rainurage annulaire. Dans les deux barres latérales sont incorporées deux fins de course (8 et 9) qui sont solidaires de la pièce d'entraînement au moyen d'une réglette commune (12) que l'on peut retirer afin de rendre indépendantes les deux fins de course et les positionner dans la position axialement distante correspondant aux situations de montée et de descente de la porte, la pièce d'entraînement étant l'élément d'actionnement des microrupteurs des fins de course. Le blocage de chaque fin de course dans sa position sélectionnée s'effectue compte tenu du fait que chaque fin de course possède, outre son microrupteur correspondant, un doigt basculant (11) qui se plante dans les rainures de la barre striée sur laquelle il glisse lorsque la pièce d'entraînement, qui le maintenait déconnecté, s'éloigne.
