The balustrade 3 is provided with an endless moving handrail 4. The steps and the moving handrail 4 are circulated while being synchronized.

  In the passenger conveyor 1 having such a configuration, the passenger gets on the step from one of the lower entrance 2 and the upper entrance and grabs the movable handrail 4 as appropriate. Thereby, a passenger can move safely to the other of the lower entrance 2 and the upper entrance.

  In FIG. 1, the passenger conveyor 1 is in the ascending operation. That is, the passenger can move from the lower entrance 2 to the upper entrance using the passenger conveyor 1.

  In the present embodiment, a load detection device 6 that is used for the operation control device is provided below the entrance, that is, below the floor board 5 of the lower entrance 2. The load detection device 6 has a function of detecting a vertically downward load applied to the floor board 5.

Next, the operation control apparatus will be described in more detail with reference to FIG.
FIG. 2 is an enlarged view of a main part of the passenger conveyor operation control apparatus according to Embodiment 1 of the present invention.

  In FIG. 2, reference numeral 7 denotes a truss beam of the passenger conveyor 1. A support plate 8 is provided on the upper surface of the truss beam 7. An elastic body 9 is provided between the upper surface of the support plate 8 and the lower surface of the floor plate 5. The elastic body 9 is made of rubber or a coil spring. The elastic body 9 elastically supports the floor board 5 from below.

  A plurality of load detection devices 6 are provided between the support plate 8 and the lower surface of the floor plate 5. These load detection devices 6 are set so as to detect different loads. In the present embodiment, two load detection devices 6 are provided for these load detection devices 6.

  Each of these load detection devices 6 includes a first limit switch 10 and a second limit switch 11. The first and second limit switches 10 and 11 can change the setting of the detected load by changing the arrangement.

  The first limit switch 10 has a function of operating when a first detection load is applied to the floor board 5 and the floor board 5 moves downward against the elastic force of the elastic body 9. Here, the first detected load is set to a distributed load when a load of 1.5 passengers (about 90 kgf = about 882 N) is applied to one step of the passenger conveyor 1.

  The second limit switch 11 operates when a second detection load is applied to the floor board 5 and the floor board 5 moves below the operating position of the first limit switch 10 against the elastic force of the elastic body 9. Is provided. Here, the second detected load is set to a distributed load when a load of two passengers (about 120 Kgf = 1176 N) is applied to one step of the passenger conveyor 1.

  Reference numeral 12 denotes a speed control device. The speed control device 12 has a function of decelerating the passenger conveyor 1 when the first limit switch 10 operates continuously for a predetermined time. Further, the speed control device 12 has a function of stopping the passenger conveyor 1 when the second limit switch 11 operates continuously for a predetermined time.

  In the operation control device for the passenger conveyor 1 having such a configuration, when the number of people who intend to use the passenger conveyor 1 increases to some extent and the load applied to the floor board 5 reaches the first detection load, the first limit switch 10 operates.

  When this operation continues for a certain time, the speed control device 12 decelerates the passenger conveyor 1. The change in the operating speed of the passenger conveyor 1 informs the person who intends to use the passenger conveyor 1 that the situation is different from the normal situation.

  Even in such a situation, when the number of people who intend to use the passenger conveyor 1 increases and the load applied to the floor board 5 reaches the second detection load, the second limit switch 11 operates.

When this operation continues for a certain time, the speed control device 12 stops the passenger conveyor 1.
The stoppage of the passenger conveyor 1 informs the person who intends to use the passenger conveyor 1 that the passenger conveyor 1 is unusable.

  According to Embodiment 1 demonstrated above, when the load detection apparatus 6 detects the load more than a 1st detection load continuously for a fixed time, the speed control apparatus 12 decelerates the passenger conveyor 1. FIG. Moreover, when the load detection apparatus 6 detects the load more than a 2nd detection load continuously for a fixed time, the speed control apparatus 12 stops the passenger conveyor 1. FIG.

  For this reason, it is possible to alert a person who intends to use the passenger conveyor 1 and to prevent passengers exceeding the standard from getting on the step. Further, it is possible to prevent the passenger conveyor 1 during the ascending operation from descending due to an overload applied to the step.

  Further, the first detected load is set to a distributed load when a load for 1.5 passengers is applied to one step of the passenger conveyor 1. For this reason, before the load applied to the passenger conveyor 1 reaches the rated load (drive capacity load or braking capacity load), it is possible to inform the person who intends to use the passenger conveyor 1 that the situation is different from normal.

  In addition, the second detected load is set to a distributed load when a load for two passengers is applied to one step of the passenger conveyor 1. For this reason, when the load applied to the passenger conveyor 1 reaches the rated load, it is possible to inform the person who intends to use the passenger conveyor 1 that the passenger conveyor 1 is unusable.

  The load detection device 6 includes an elastic body 9, a first limit switch 10, and a second limit switch 11. For this reason, it is possible to prevent passengers exceeding the specified number from riding on the steps with a simple configuration.

  In the first embodiment, the case where the load detection device 6 is provided at the lower entrance 2 of the passenger conveyor 1 during the ascending operation has been described. However, even if the load detection device 6 is provided at the upper entrance of the passenger conveyor 1 during the descending operation, it is possible to prevent passengers exceeding a specified level from getting on the step. In this case, it is possible to prevent the descending speed of the passenger conveyor 1 from increasing.

  Moreover, in Embodiment 1, it demonstrated by the case where the load concerning the floor board 5 was detected with the 1st and 2nd limit switches 10 and 11. FIG. However, the load detection applied to the floor board 5 can also be performed by a load sensor that generates a signal by the load.

  Further, a warning device that issues a warning when the load detection device 6 continuously detects a load that is equal to or greater than the first detection load or greater than or equal to the second detection load may be provided in the passenger conveyor 1 or in the vicinity of the passenger conveyor 1. . In this case, it is possible to more reliably prevent passengers exceeding the standard from getting on the step.
