Problems solved by technology

[0004] In the above-mentioned existing sliding door device, since the two light emitters emit light at the same time, the light reflected by the obstacle is incident on the camera, making it difficult to detect that the light from the opposite light emitter is blocked by the obstacle, which may cause Detection accuracy drops

Embodiment approach 1

[0024] figure 1 It is a front view of the car door device (sliding door device) of the elevator according to Embodiment 1 of the present invention seen from inside the car. In the drawing, a car 1 ascending and descending in a hoistway is provided with a car entrance 1a. The car doorway 1a is opened and closed by first and second car doors 2a, 2b that are elevator doors that move horizontally. A car doorway frame 3 is provided around the car doorway 1a.

[0025] The car doorway frame 3 has: first and second vertical frames 3a, 3b provided on the left and right sides of the car doorway 1a; an upper horizontal frame 3c provided between the upper ends of the first and second vertical frames 3a, 3b; And the lower horizontal frame 3d provided on the floor portion of the car entrance 1a.

[0026] A car operation panel 4 is provided on the front surface of the second vertical frame 3b. The car operation panel 4 is provided with a display device 5 , an alarm device 6 , a plurality...

Embodiment approach 2

[0053] under, Figure 9 It is an explanatory diagram showing the lighting timing of the first and second light emitters and the imaging timing of the first and second cameras according to Embodiment 2 of the present invention. Embodiment 2 replaces Embodiment 1 ( image 3 ) in step 2 and step 3, other structures and control methods are the same as in Embodiment 1.

[0054] In this way, even if the first and second off-time images are acquired before the second on-time image is acquired, similar to the first embodiment, it is possible to eliminate the influence of light reflected by obstacles and detect obstacles more reliably.

Embodiment approach 3

[0056] under, Figure 10 It is a front view of the landing door device (sliding door device) of the elevator according to Embodiment 3 of the present invention seen from the landing. In the figure, the landing entrance 21 is provided in the landing. The hall doorway 21 is opened and closed by first and second hall doors 22a, 22b that are elevator doors that move horizontally in conjunction with the car doors 2a, 2b. A hall doorway frame 23 is provided around the hall doorway 21 .

[0057] The landing doorway frame 23 has: first and second vertical frames 23a, 23b provided on the left and right sides of the landing doorway 21; an upper horizontal frame 23c provided between the upper ends of the first and second vertical frames 23a, 23b; And the lower horizontal frame 23d provided in the floor part of the boarding point entrance / exit 21.

[0058] In front of the first vertical frame 23a, a display device 24, an alarm device 25, an up call button 26, and a down call button 27 ...

Abstract

A slide door device in which a first light emitter and first imaging means are arranged on one side of a doorway and a second light emitter and second imaging means are arranged on the other side. The first light emitter has a first light emission surface, and the second light emitter has a second light emission surface facing the first light emission surface. A control device controls the first and second light emitters and the first and second imaging means to detect an obstacle in the vicinity of the doorway, and the control device also controls opening and closing of a door depending on whether or not an obstacle is present. Further, the control device causes the first and second light emitters to emit light at timings offset from each other.

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, the left and right vertical frames of the entrance and exit are provided with: a pair of light emitters with long and continuous light-emitting surfaces; The whole is included in the monitoring area (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-338846 [0004] In the above-mentioned existing sliding door device, since the two light emitters emit light at the same time, the light reflected by the obstacle is incident on the camera, making it difficult to detect that the light from the opposite light emitter is blocked by the obstacle, which may cause Detection accuracy drops. Contents of the invention [0005] The present invention is proposed to solve the above problems, and its...
