Description

  The present invention relates to a passenger conveyor operating method and apparatus.

  Conventionally, a passenger conveyor has a structure in which an upper sprocket driven by a driving device arranged on the upper side in the main frame of the conveyor and a lower sprocket corresponding to the upper sprocket are arranged, and a step chain is spanned between both sprockets. In this, a number of steps are arranged.

  By the way, if there is a crowded situation at the entrance / exit of the passenger conveyor, especially if the congestion situation at the exit / exit continues, there is a possibility that the safety of passengers may not be protected. Means are provided for installing a broadcasting device capable of notifying passengers who are moving the place (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 5-294591

  Even if the passenger conveyor provided with a conventional broadcasting device is in a crowded situation at the entrance and exit, the passenger conveyor itself maintains constant speed operation, so as a means to ensure passenger safety only with broadcasting means There was a problem that an effective effect could not be obtained.

  The present invention has been made to solve the above-described problems. Even when the passenger is congested due to the stagnation of passengers at the entrance / exit of the passenger conveyor, the safety of passengers at the entrance / exit of the passengers at the entrance / exit is ensured simultaneously. It is an object of the present invention to provide a passenger conveyor operating method and apparatus capable of smoothing the flow.

  In the passenger conveyor operating method according to claim 1 of the present invention, the load applied to the floor surface of the passenger entrance of the passenger conveyor is detected, and when the detected value exceeds the set load range, or the detected value falls below the set load range. In this case, the passenger conveyor is slowly decelerated or stopped, and the normal operation is performed from the slowly accelerated operation after the detected value reaches the set load range.

  According to the passenger conveyor operating method according to claim 1 of the present invention, the load applied to the floor surface of the passenger conveyor entrance is detected, and when the detected value exceeds the set load range, or the detected value falls within the set load range. When the speed is lower, the passenger conveyor is slowly decelerated or stopped, and after the detected value reaches the set load range, normal operation is performed from the slow speed, and the detected value of the load applied to the floor of the entrance / exit If the vehicle exceeds the load normally assumed (corresponding to the number of passengers assumed on the floor), or if the detected value falls below the load assumed, the passenger conveyor is slowly decelerated or stopped. Even if there is congestion due to stagnation at the entrance / exit floor, the safety of passengers on the steps is ensured, the flow of passengers at the entrance / exit is smoothed, and driving suitable for the passenger's usage situation is possible, and further setting Load range If it does not reach becomes possible to stop the operation, this power dissipation is reduced.

Embodiment 1 FIG.
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a side view of an upper portion serving as an entrance / exit of a passenger conveyor device according to Embodiment 1 of the present invention. In FIG. 1, a floor surface 1 at a passenger entrance / exit is a beam 3a provided on a passenger conveyor main frame 2. It is installed in a state supported by 3b.
4a and 4b are load detectors, which are arranged between the floor surface 1 and the beams 3a and 3b.
As the load detectors 4a and 4b, for example, load converters such as compression type load cells are used.
Moreover, although the load detectors 4a and 4b shown in FIG. 1 are so-called plural arrangements provided at respective portions of the beams 3a and 3b, a single installation may be used.

The following operation will be described.
When the passenger moves to the entrance and exits and passes over the floor surface 1, the load value of the passenger is measured by the load detectors 4a and 4b.
By setting the initial state to the own weight of the floor surface 1 itself, the load value as a variation due to the passenger's load can be measured. By measuring and recording the fluctuation value of this load, the weight of the passenger or cargo moving on the floor surface 1 can be grasped.
At this time, by registering a load in which the number of passengers that can be ridden on the floor surface 1 is registered as a set load, a comparison with the set load is performed (arithmetic processing), thereby overcrowding the passengers on the floor surface 1. It is possible to identify whether there is a state and whether an unexpected heavy object is loaded.

Embodiment 2. FIG.
FIG. 2 is a side view of the upper part of the passenger conveyor apparatus according to the second embodiment of the present invention, which is substantially the same structure as the apparatus shown in the first embodiment, except that the floor surface 1 is narrowed. Divided parts 1a and 1b are provided with load detectors 4a, 4b, 4c and 4d, respectively. By subdividing the floor surface 1, the detected load W1 when passing on the floor surface 1a and the floor It is possible to measure the detected load W2 when passing on the surface 1b, and to grasp the moving state of the passenger or the cargo or the deviation of the passenger or the cargo on the floor surface, that is, the partial concentration state.

Embodiment 3 FIG.
FIG. 3 is a configuration diagram of the operation control means of the passenger conveyor device using the load detection device according to Embodiment 3 of the present invention. 4a, 4b are load detectors, 5 is a drive device, 6 is a control device, 7a, 7b is an information transmission means.

The steps of the passenger conveyor are driven by the drive device 5 and are controlled by the control device 6.
The control device 6 operates by outputting an operation command to the drive device 5 when the load detectors 4a and 4b detect passage of passengers or cargo.
The information transmission means 7a and 7b transmit guidance, warning, etc. by voice or light emission, etc., and by using this together with the load detectors 4a and 4b, the stagnation of passengers at the entrance and exit of the passenger conveyor When the vehicle is congested on the floor, there is an effect that it is possible to ensure the safety of the passengers on the step and at the same time to operate the passengers more smoothly at the passenger ports.

FIG. 4 is a flowchart showing an example of the operation of the passenger conveyor according to the present invention, which will be described below.
First, the passenger conveyor is activated, a steady operation (step 8) is performed, and it is determined whether or not to continue the operation (whether or not the stop switch is activated) (step 9).
When not stopping, the load value detected by the load detector 4a ... is compared with the set load value, that is, the load in which the number of passengers who can ride on the floor surface 1 is set (step 10). Then, it is determined that the weight is excessive, a slow deceleration command is issued, and the transition of the steps of the passenger conveyor is decelerated (step 11).
At the same time, the information transmission means 7a and 7b are operated (step 11). Again, if the load value detected by the load detectors 4a exceeds the set load, the step is gently stopped (steps 12 and 13).

  When the detected load value is smaller than the set load value in step 10, it is further determined whether the minimum installed load value, that is, the own weight value of the floor surface 1 or the like is less than or equal to (step 14). In this case, the steady operation is continued, and when it is less than or equal to the minimum set load value, the deceleration operation by the slow deceleration command is performed (step 15).

The operation time is counted by a timer (step 16), and if the load value is maintained even after a certain time, for example, one round of the step, the step is gently stopped (step 17). If the specified time is not exceeded, maintain slow deceleration operation.
Further, it is determined whether or not the detected load value exceeds the minimum set load value (step 18). If it does not exceed, the stopped state is maintained, and if it exceeds, the slow acceleration is started and the steady operation is performed (step 8).

As described above, according to the above-described embodiment, when congestion occurs due to stagnation of passengers on the passenger conveyor or on the floor surface 1, the safety of passengers on the steps is ensured and at the same time The flow can be made smooth, and driving suitable for the use situation of passengers becomes possible.
In addition, since the load detector is applied, it is possible to cope with an easy configuration, and when it is not in a normal usage form, for example, when it is used for transporting vending machines and their contents and other heavy objects. Since the information transmission means is used in combination, unauthorized operation is avoided by the operation of the information transmission means, and damage to each device constituting the passenger conveyor and occurrence of an accident are prevented in advance.
In addition, when the set load range value is not reached, the operation can be stopped to save energy.
