Problems solved by technology

Therefore, when this sliding door is applied to an elevator, the door may be reversed to open several times when closing the door, resulting in a decrease in operating efficiency.
In addition, in order to detect obstacles from the landing side, it is necessary to install light emitters and cameras at each landing, resulting in increased costs

Embodiment approach 1

[0042] figure 1 It is a block diagram showing the elevator according to Embodiment 1 of the present invention. In the drawing, a winding device 2 is provided on the upper portion of the hoistway 1 . The winding device 2 has a spool 3 and a winding motor 4 that rotates the spool 3 . A wire rope 5 serving as a suspension means is wound around the drum 3 .

[0043] A car 6 as a lifting body is connected to the end of the steel rope 5 . The car 6 is suspended in the hoistway 1 by the steel rope 5 , and is lifted and lowered in the hoistway 1 by the winding device 2 . A plurality of car guide rails 7 are provided in the hoistway 1 to guide the raising and lowering of the car 6 .

[0044] The car 6 has a car frame 8 connected to the rope 5 and a car chamber 9 supported by the car frame 8 . On the front of the car chamber 9, a car doorway 10 is provided as a first doorway. The hall 11 is provided with a hall doorway 12 as a second doorway. The car doorway 10 and the landing do...

Embodiment approach 2

[0071] Next, Figure 10 It is a horizontal cross-sectional view of the sliding door device of an elevator according to Embodiment 2 of the present invention, Figure 11 It is viewed from the landing side Figure 10 Front view of the car door mechanism in . In the drawing, the light emitter 32 is attached to the door-closing side end of the front surface (the surface facing the landing door 29 ) of the car door 22 . That is, the light emitter 32 and the car door 22 move together.

[0072] In addition, the first camera 34 is disposed at a height different from that of the upper end portion of the light emitting surface 32a. Here, the first camera 34 is disposed at a position lower than the upper end portion of the light emitting surface 32a. Furthermore, the first camera 34 is arranged such that the straight line B connecting the upper end of the light emitting surface 32 a and the first camera 34 is always non-parallel to the optical axis A of the lens system of the first c...

Embodiment approach 3

[0083] Next, Figure 15 It is a schematic block diagram showing a control circuit of a sliding door apparatus for an elevator according to Embodiment 3 of the present invention. In the drawing, a door position measuring device 45 is provided at the drive portion of the car doors 21, 22, and outputs signals corresponding to the positions of the car doors 21, 22. For example, an encoder mounted on a motor of the door driving device 15 can be used as the door position measuring device 45 . The image length judging unit 40 sends information on the reference length of the luminous surface image corresponding to the positions of the car doors 21 and 22 to the image processing judging unit 42 based on the information from the door position measuring device 45 . The control device has an opening and closing control unit 41 , an image processing determination unit 42 , a main control unit 43 , and an image length determination unit 40 . Other structures are the same as those in Embod...

Abstract

In a slide door device, a first doorway is opened and closed by a first door and a second doorway facing the first doorway is opened and closed by a second door. At a side portion of the space between the first doorway and the second doorway, there is placed imaging means for imaging the space side. An image processing and determination section determines, based on image data from the imaging means, whether there is an obstacle in the space.

Description

technical field [0001] The present invention relates to a sliding door device for automatically moving a door horizontally and an elevator using the sliding door device. Background technique [0002] In the existing sliding door device, a light emitter with a long and continuous light-emitting surface is provided on one of the vertical frames on the left and right of the entrance, and a light-emitting device for photographing the light-emitting surface is provided on the vertical frame opposite to the light emitter. Camera (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-338846 [0004] In the conventional sliding door device as described above, since the light emitter and the camera are installed on the vertical frame, when a part of passengers or luggage approaches the door, sometimes it will be lost even at a position where it is not actually caught by the door. will be detected as an obstacle. Therefore, when th...
