no. 1 approach

[0054] figure 1 It is a figure which shows the overall schematic structure of the escalator in 1st Embodiment. 10 in the figure represents the whole escalator.

[0055] The escalator 10 is, for example, installed obliquely between the upper and lower floors of a building, and circulates a plurality of steps (steps) 11 between the landing of the upper machine room 12 and the landing of the lower machine room 13 . Each rung 11 utilizes figure 2 The illustrated endless link chains 14 are connected to each other and arranged in a truss 15 installed under the floor of the building. Inside the truss 15, an upper sprocket 16 and a lower sprocket 17 are arranged, and a connecting chain 14 is wound between them.

[0056] A driving device 18 having a motor, a speed reducer, or the like is coupled to either one of the upper sprocket 16 and the lower sprocket 17 (in this example, the upper sprocket 16 ). Driven by the driving device 18, the sprockets 16 and 17 rotate, and the plurali...

no. 2 approach

[0110] Next, a second embodiment will be described.

[0111] The above-mentioned first embodiment is a mirror system in which two optical axes are formed using a reflector, whereas the second embodiment is a mirrorless system in which two optical axes are formed without using a reflector.

[0112] Figure 16 It is a figure which shows the structure of the abnormality detection system of a mirrorless system in 2nd Embodiment.

[0113] On the circuit side of the escalator 10, the left wheel 27a and the right wheel 27b of the step 11 are supported by a pair of guide rails 31a, 31b provided on both sides of the step 11, and move from left to right. The difference from the above-mentioned first embodiment is that there is no reflector 53 as a reflector, and instead, two sets of transmissive photoelectric sensors 70a, 70b are used to form two optical axes 73a, 70b on the travel paths of the wheels 27a, 27b. 73b.

[0114] The first transmissive photoelectric sensor 70a is separate...

no. 3 approach

[0135] Next, a third embodiment will be described.

[0136] The third embodiment is a configuration in which two optical axes cross each other in a mirrorless abnormality detection system.

[0137] Figure 19 It is a figure which shows the structure of the abnormality detection system of a mirrorless system in 3rd Embodiment. In addition, the same code|symbol is attached|subjected to the same part as said 2nd Embodiment, and it demonstrates.

[0138] There is a configuration in which the passage of the left wheel 27a and the right wheel 27b of the step 11 is detected at two positions using two sets of transmissive photoelectric sensors 70a and 70b. The difference from the above-mentioned second embodiment is that the optical axis 73a of the first transmissive photoelectric sensor 70a intersects with the optical axis 73b of the second transmissive photoelectric sensor 70b.

[0139] That is, the light projection part 71a and the light projection part 71b are spaced apart by a...

Abstract

The present invention provides an anomaly detecting system capable of determining a symptom of an anomaly of a wheel during operation and responding before entering a state in which an emergency stopis required. The anomaly detecting system of a passenger conveyor of one embodiment uses a light projecting portion (51),a light receiving portion (52) and a mirror (53) of a transmissive photoelectric sensor (50) to form two optical axes (54, 55) on the traveling path of the wheel (27). The displacement of the wheel 27 in the width direction of the guide rail is detected based on time of the wheel traveling through the two optical axes (54, 55), the traveling speed of a step (11), and the positional relationship of the two optical axes (54, 55).

Description

technical field [0001] Embodiments of the present invention relate to an abnormality detection system of passenger conveyors such as escalators and moving walks. Background technique [0002] A passenger conveyor (man conveyor) such as an escalator or a moving walk has a plurality of steps (steps) connected in a loop by a chain. Driven by a motor, these steps are circularly moved along the guide rails arranged inside the truss, so that passengers riding on the steps are transported from one landing to another landing. [0003] On the left and right sides of the steps, front wheels pivotally supported by the chain and rear wheels mounted below the riser surfaces (kick plates) of the steps are provided. These wheels (front wheels and rear wheels) are composed of rubber rollers and bearings that rotatably support the rubber rollers, and move on guide rails. [0004] Here, when the passenger conveyor is operated for a long time, the rubber roller of the wheel may deteriorate, ...
