Embodiment approach 1
[0028] refer to Figure 1 ~ Figure 2 The escalator 10 of Embodiment 1 is demonstrated.
[0029] (1) Escalator 10
[0030] based on figure 1 The structure of the escalator 10 is demonstrated. figure 1 It is explanatory drawing which looked at the escalator 10 from a side.
[0031] The frame of the escalator 10 , that is, the truss 12 spans the upper and lower floors of the building 1 and is supported using support angle irons 2 , 3 .
[0032] Inside the machine room 14 on the upper side of the upper end of the truss 12, a driving device 18 for running the steps 30, a pair of left and right drive sprockets 24, 24, and a pair of left and right handrail belt sprockets 27, 27 are provided. The driving device 18 has: a motor 20 composed of an induction motor (induction motor); a speed reducer; an output sprocket mounted on an output shaft of the speed reducer; a driving chain 22 driven by the output sprocket; Disc brakes that stop and stay stopped. The drive sprocket 24 is rot...
Embodiment approach 2
[0056] Next, refer to image 3 The escalator 10 of Embodiment 2 is demonstrated.
[0057] In the past, even in the case of installing the first sensor and the second sensor, there are cases where the first sensor is respectively installed on the left and right pair of railings 36, the second sensor is respectively installed on the left and right pair of railings 36, and a total of four sensors are installed. situation.
[0058] In this embodiment, an embodiment will be described in which, even when such a pair of left and right sensors are provided, it is possible to perform operation from a stopped state to a low speed and acceleration from a low speed to a rated speed with one type of sensor. for normal operation.
[0059] The difference between this embodiment and Embodiment 1 is that, as image 3 As shown, the area sensor 70 is disposed opposite to the sides of the skirt 44 of the pair of left and right railings 36 , 36 , respectively.
[0060] The first detection rang...

Abstract
The present invention provides a passenger conveyor capable of switching from a stopped state to a low speed operation and a normal speed from a low speed to a rated speed by one sensor. The area sensor (70) is placed at the entrance of the railing (36). The area sensor (70) outputs a detection signal including the detection distance to the control unit (50) when the passenger is detected within the first detection range. The control unit (50) accelerates the step (30) from the stopped state to the low speed when the detection signal is input. When the detection distance included in the detection signal is shorter than the set distance, it is assumed that the passenger enters the second detection range, and the step (30) is accelerated from the low speed to the rated speed.
Description
[0001] This application is based on Japanese patent application 2016-239022 (filing date: December 09, 2016), and enjoys the priority benefit of this application. This application incorporates the entire contents of this application by reference. technical field [0002] Embodiments of the present invention relate to a passenger conveyor. Background technique [0003] In passenger conveyors such as escalators and moving walkways, the steps are stopped to save energy when no passengers are on board. Then, when a passenger is detected, the step is raised from a stopped state to a predetermined low speed, and then raised to a rated speed to perform normal operation. [0004] In the above-mentioned passenger conveyor, conventionally, two sensors for detecting passengers are provided, and when the first sensor detects a passenger, it starts to run at a low speed from a stop state, and when the second sensor detects a passenger, it runs at a low speed. The low speed speed is inc...
