Problems solved by technology

However, even if the passenger conveyor is stopped after the pedal is deformed so that the comb plate comes into contact with the pedal to apply pressure to the valleys of the comb teeth, there is a high possibility that the comb teeth and the pedal have been damaged, and the repair of the passenger conveyor takes a long time. time

no. 1 Embodiment approach example

[0043] figure 1 It is a schematic configuration diagram schematically showing the passenger conveyor 1 .

[0044] The passenger conveying facility 1 is an inclined passenger conveying facility, that is, a so-called escalator, installed between an upper floor 100 and a lower floor 101 of a building structure. The passenger conveyor 1 includes a housing 2 , an upper access floor 3 a , a lower access floor 3 b , a handrail 4 , a handrail 5 , a plurality of steps 6 , a control unit 7 , and a drive unit 8 .

[0045] The housing 2 is installed across the upper floor 100 and the lower floor 101 . The housing 2 is composed of an upper horizontal section 9A, a lower horizontal section 9B, and an inclined section 9C. Hereinafter, the direction extending from the lower floor 101 to the upper floor 100 in the frame 2 is referred to as the longitudinal direction of the frame 2 . In addition, let the left-right direction in the state which looked at the housing 2 from the lower floor 101...

no. 2 Embodiment approach example

[0092] In this embodiment example, the control unit 7 of the passenger conveyor 1 that detects a failure of the displacement detection sensor 17 itself and adjusts the value of the sensor output of the displacement detection sensor 17 will be described.

[0093] Figure 8 It is a flowchart showing an example of processing by the control unit 7 for detecting an abnormality of the pedal 11 . The control unit 7 can automatically perform adjustment and failure judgment of the displacement detection sensor 17 . In the figure, the displacement detection sensor 17 is simply referred to as "sensor". In addition, in Figure 8 In the shown processing, an example using the displacement detection unit 16a provided on the upper access floor 3a will be mainly described, and an example using the displacement detection unit 16b provided on the lower access floor 3b that performs the same operation will be omitted.

[0094] First, the control unit 7 determines whether or not the passenger c...

Abstract

The invention provides a passenger conveying device, an abnormality detection device of the passenger conveying device and an anomaly detection method of the passenger conveying device. When a foreignmatter enters a gap between a comb plate and a pedal, the passenger conveying device is controlled to stop, and the possibility of damage to the comb plate and the pedal is high. A displacement detection part is arranged on a comb plate arranged on one side opposite to the pedal, detects the displacement of the pedal which moves horizontally in the height direction. When the displacement amount that deviates from the reference displacement calculated on the basis of the displacement of the pedal exceeds a threshold value used for detecting an abnormality of the pedal before the pedal is in contact with the comb teeth, and the control part detects that an abnormality occurs in the pedal, different actions which correspond to the abnormality of the pedal are performed according to differentthreshold values which are exceeded by the displacement amount deviating from the reference displacement.

Description

technical field [0001] The invention relates to passenger conveying equipment, an abnormality detecting device for passenger conveying equipment and an abnormality detecting method for passenger conveying equipment. Background technique [0002] In general, an escalator as an example of passenger conveyance equipment includes a frame provided across an upper floor and a lower floor, a guide rail attached to the frame, and a plurality of steps that circulate while being guided by the guide rail. An endless step chain is connected to a plurality of steps, and the step chain is rotationally driven by a drive mechanism, whereby the plurality of steps circulates. [0003] Patent Document 1 discloses a safety device for passenger conveyance equipment, which is provided with a pressure-sensitive element provided on the back side of the front end side of the comb plate of the entrance (the top of the valley between the comb teeth). ), which stops the passenger conveyor in response ...
