Definitions

  • the present invention relates to an elevator door control device.
  • the elevator door control device is a device in which the torque of a door motor or the like is transmitted to a door panel via a transmission mechanism, and thereby a car door is automatically opened and closed in the horizontal direction.
  • a position switch for detecting that the door panel lies at the full-open position and the full-close position is generally provided.
  • a light switch which detects the full-open position and the full-close position by utilizing light shield (shading) or reflection, has been widely used because of being highly accurate as compared with switches of other types such as a mechanical switch and being relatively invulnerable to foreign matters, water, and the like.
  • the conventional elevator door control device has been a device in which the position of elevator door is detected by this light switch (light transmitting/receiving device).
  • This control device is designed to prevent the door panel from being operated at a high speed by malfunction occurring on account of the hindrance of light passage caused by dust, oil, and the like sticking to the detecting element of the light switch.
  • control device As the control device as described above, there has been known a control device that is provided with a total of three light switches: one light switch for detecting, by shading, that the door panel lies at the full-open position, and two light switches for detecting, by shading, that the door panel comes close to the full-close position, and these light switches control the travel speed of door panel so as to become slow when the light switch is shaded by a light shielding plate provided on the door panel (for example, refer to Patent Literature 1).
  • an elevator door control device that is a control device for likewise detecting the door position by using a light switch (light transmitting/receiving device), and is designed to prevent the malfunction of door occurring on account of the irradiation of external light even in the case where the light switch is irradiated with external light

  • the door position can be recognized by one or more shield plates provided on the door panel traversing the light transmitting/receiving devices of a plurality of position switches provided along the travel direction of door panel.
  • the elevator door control device since the plural numbers of position switches, which are the light transmitting/receiving devices that are generally more expensive than the shield plates, are used, the elevator door control device has a problem in that the whole of the control device also becomes expensive, and the cost increases.
  • a configuration in which one position switch and two shield plates are provided, and thereby the full open position and the full close position of door panel are detected is also conceivable.
  • the same detection signal is generated from the position switch. Therefore, this configuration has a problem that the control device and the like cannot judge which of the full open position and the full close position is the position of door panel.
