Description

The present invention relates to a step balustrade detection device for a passenger conveyor that detects that a foreign substance is caught in a gap between a step and a balustrade.

Conventionally, there is known an escalator step balustrade gap detection device provided on a truss and provided with a skirt guard switch for detecting foreign matter being caught between a step and a balustrade skirt guard. The skirt guard switch is arranged so that the skirt guard is sandwiched between the step and the skirt guard switch. When a foreign object is caught in the gap between the step and the skirt guard, the skirt guard is pushed toward the skirt guard switch, and the skirt guard switch detects the displacement of the skirt guard. As a result, it is detected that a foreign substance is caught in the gap between the step and the skirt guard (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 10-279246

However, there is a time lag between the time when a foreign object is caught in the gap between the step and the balustrade and the time when the skirt guard switch detects the displacement of the balustrade. As a result, it takes time to detect that a foreign substance is caught in the gap between the step and the balustrade. As a result, there is a problem that it takes a lot of time from the time when a foreign substance is caught in the gap between the step and the balustrade to the time when the step is stopped in an emergency.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a passenger conveyor capable of faster detecting that a foreign substance is caught in a gap between a step and a balustrade. It provides a detection device for sandwiching a step balustrade gap.

The step balustrade gap detection device of the passenger conveyor according to the present invention is a light emitting device that emits light upward from the gap between the step and the balustrade, a camera that captures the gap and the moving handrail from above, and a camera. In the image, the image analysis device that extracts the gap shading part that is the part that is shaded in the gap and the object placement part that is the part where the object is placed on the moving handrail, and the image analysis device that extracts it. It is provided with a gap foreign matter pinching determination device for determining whether or not a foreign matter is pinched in the gap based on the gap light-shielding portion and the object placement portion.

According to the step balustrade crevice detection device of the passenger conveyor according to the present invention, the crevice shading portion and the object mounting portion are extracted from the image taken by the camera, and the extracted crevice shading portion and the object mounting portion are extracted. Based on, it is determined whether or not a foreign substance is caught in the gap. As a result, it is possible to detect that a foreign substance is caught in the gap between the step and the balustrade more quickly.

When the user 9 is riding on the moving handrail 3, the dimension of the gap shading portion in the moving direction of the step 1 is larger than the reference value which is a preset value in the image taken by the camera 6. The user ride-on determination device 83 determines whether or not the dimension of the gap shading portion in the moving direction is larger than the reference value. When it is determined that the dimension of the gap shading portion in the moving direction is larger than the reference value, the user ride-on determination device 83 determines that the user 9 has climbed onto the moving handrail 3. The reference value is 30 cm. The reference value is not limited to this, and may be another value.

When it is determined that the user 9 is sandwiched between the gap G between the step 1 and the balustrade 2, the control panel main body 81 stops the movement of the step 1 and the moving handrail 3. It should be noted that the movement of the step 1 and the moving handrail 3 may be decelerated instead of stopping the movement of the step 1 and the moving handrail 3. Further, in this case, the notification control unit 84 causes the notification device 4 to notify the user about the alert.

When it is determined that the user 9 has climbed onto the moving handrail 3, the control panel main body 81 stops the movement of the step 1 and the moving handrail 3, respectively. It should be noted that the movement of the step 1 and the moving handrail 3 may be decelerated instead of stopping the movement of the step 1 and the moving handrail 3. Further, in this case, the notification control unit 84 causes the notification device 4 to notify the user about the alert.

The escalator step balustrade gap detection device that detects that foreign matter is caught in the gap G between the step 1 and the balustrade 2 is a notification device 4, a light emitting device 5, a camera 6, an image analysis device 7, and a gap foreign matter pinch.
