The present invention relates to a variable-speed passenger conveying device and its operating method, in particular to a variable-speed passenger conveying device with a large speed difference between boarding and stepping out and its operating method.

Background technique

[0002]

Generally speaking, for the purpose of energy saving and improvement of passenger transport capacity, according to the degree of congestion of passengers, as a variable-speed passenger conveying equipment, the moving speed is switched to three or more gears, such as Patent Document 1. Japanese Patent Laid-Open No. 2004- The variable-speed passenger conveying equipment disclosed in the 224539 communiqué.

Contents of the invention

[0004]

In the variable-speed passenger conveying apparatus disclosed in Patent Document 1 above, when it is necessary to increase the speed from the initial moving speed to a high speed, for example, due to the crowding of passengers, it does not wait for the passenger who got on at the initial moving speed to step out of the pedal. Start to speed up, because the passenger who is riding in at the initial moving speed has a large speed difference when stepping out of the pedal compared with the moving speed when he was riding in, so it is possible that when stepping out of the pedal Create fear. As a result, the occupants feel uneasy about their own actions when stepping off the steps, and this creates a psychological burden, which may cause them to fall near the step exit.

[0005]

An object of the present invention is to provide a variable-speed passenger conveying device that does not cause passengers who get on at the initial moving speed to increase the speed of the moving speed from the initial moving speed to a high speed. Feeling uneasy when stepping off the pedal.

[0006]

In order to achieve the above object, the variable-speed passenger conveying equipment of the present invention is constituted as follows: when increasing the moving speed from the initial moving speed to a high-speed moving speed, firstly, the moving speed is increased to a value between the initial moving speed and the speed to which the speed should be increased. The intermediate moving speed between the high-speed moving speeds, and after running for a specified time, increase the moving speed to the high-speed moving speed that should be increased to. Here, if it is a variable-speed passenger conveyor whose moving speed is set to multiple moving speeds, the so-called intermediate moving speed may be the set intermediate moving speed, or it may be between the initial moving speed and the speed to be increased. An intermediate movement speed halfway between the high speeds reached. In addition, in the case of a variable-speed passenger conveyor whose moving speed is set to the second-speed moving speed, the intermediate moving speed refers to one-half between the initial moving speed and the high-speed moving speed to which the speed should be increased. The intermediate movement speed at .

[0007]

By first increasing the moving speed to the above-mentioned intermediate moving speed, and after running for a specified time, increasing the moving speed to the specified high-speed moving speed, the passenger who rides in at the initial moving speed can move at a different speed. Stepping out of the pedals within a specified time without becoming excessively large, does not cause a sense of fear due to a large difference in moving speed when stepping out of the pedals, and can reduce anxiety about the movement when stepping out of the pedals. And, as a variable-speed passenger conveying device, it can finally increase the moving speed from the initial moving speed to a high-speed moving speed. In addition, since the speed difference between the intermediate moving speed and the high-speed moving speed that should be accelerated to is the same as the speed difference between the initial moving speed and the intermediate moving speed, the passengers who get in after accelerating to the intermediate moving speed are the same as Passengers who get in at the initial moving speed will not feel too large a difference in moving speed when they step out of the pedals after increasing the speed to the intermediate moving speed.

Invention effect

Specific implementation form

[0009]

Hereinafter, a first embodiment of the variable-speed passenger conveyor according to the present invention, that is, a horizontally-arranged variable-speed electric tunnel with no height difference between steps will be described with reference to FIGS. 1 to 3 .

[0010]

The variable-speed electric tunnel 1 has a body frame 2 arranged between floors separated by a predetermined distance, a plurality of pedals 3 arranged in the body frame 2 and guided by it to move cyclically, and arranged on the length of the body frame 2. The entrance side floor 4 and the exit floor side floor 5 for riding in and stepping out of the pedal 3 on both ends of the direction, the pedal chain 6 connecting the plurality of pedals 3 in an endless form, and The two ends of the length direction of the body frame 2 hang the driving sprocket 7 and the driven sprocket 8 of the endless pedal chain 6, and the driving motor 9 for driving the driving sprocket 7 to run. Both sides of the moving direction of the pedal 3 are vertically supported on the railing 10 on the body frame 2 and the moving handrail 11 that moves synchronously with the pedal 3 under the guidance of the periphery of the railing 10 .

[0011]

The driving motor 9 is set to be powered by an inverter device 12, which can make the moving speed of the pedal 3, that is, the moving speed of the variable-speed electric channel 1, for example, within the speed range of 0-40m per minute. variable speed. The inverter device 12 receives a command signal from the control device 13 to change the moving speed of the pedal 3, thereby controlling the rotation speed of the drive motor 9. A programmed moving speed change command signal is output to the inverter device 12 at a set time, or an operator operates the switch 15 to output a moving speed change command signal to the inverter device 12 .

[0012]

In the above configuration, the inverter device 12, the control device 13, the timer 14, and the changeover switch 15 correspond to the speed switching device for switching the pedal moving speed in the present invention.

[0013]

The operation mode of the variable-speed electric tunnel 1 having the above-mentioned structure will be described below with reference to FIG. 1 .

[Operation mode 1]

In the variable-speed electric tunnel 1 that can operate at a moving speed of up to 40 m/min in order to increase the transport capacity of passengers, the pedal 3 is stopped for energy-saving operation if there are no passengers after activation. After the stop operation lasted for a period of time, because it was close to the time period when a large number of passengers were expected to ride in, the timer 14 or the switch 15 output a signal to the control device 13, and after the control device 13 received the signal, it sent a signal to the inverter device 12. After outputting the moving speed change command signal, the inverter device 12 increases the rotational speed of the driving motor 9 and increases the moving speed of the pedal 3 to a maximum speed of 40 m/min in the order of a→b→c. Then, run according to the order of d→e, after the passenger rush hour passes, in order to carry out energy-saving operation again, make the pedal 3 that runs with the speed of 40 m/min stop moving according to the order of e→f→g.

[0014]

At this time, the passenger who rides on the pedal 3 at a moving speed of 40 m/min will not feel the pedal 3 when stepping out because the pedal still moves at a speed of 40 m/min and the moving speed remains unchanged. Poor movement speed.

[Operation mode 2]

In the variable-speed electric tunnel 1 that can operate at a moving speed of up to 40 m/min in order to increase the transport capacity of passengers, after starting, if there are no passengers, the pedal 3 is operated in the order of a → h in order to perform energy-saving operation. For example, run at a low speed of 20 m/min. After running at this speed for a period of time, because it is close to the time period when a large number of passengers are expected to take in, so by the operation of timer 14 or switch 15, the moving speed is changed from 20 meters to 20 meters according to the order of h→i→j→d. /min up to 40m/min at high speed. Then, after running in the order of d→e, after the rush hour for passengers has passed, in order to perform energy-saving operation again, the pedal 3 running at a speed of 40 m/min is made to run at a speed of 20 m/min again in the order of e→f→k. The speed runs, and then stops running in the order of k→l.

[0015]

At this time, the passenger who rides on the pedal 3 at a moving speed of 40 m/min will not feel the pedal 3 when stepping out because the pedal still moves at a speed of 40 m/min and the moving speed remains unchanged. Poor movement speed.

[Operation mode 3]

In the variable-speed electric tunnel 1 that can operate at a moving speed of up to 40 m/min in order to increase the transport capacity of passengers, after starting, if there are no passengers, the pedal 3 is operated in the order of a → h in order to perform energy-saving operation. For example, run at a speed of 20 m/min. After running at this speed for a period of time, although some passengers get in, because it is an idle period, the moving speed is not converted to a speed of 40 m/min. Therefore, the passenger who rides into the pedal 3 at a speed of 20 m/min will not feel the speed difference when stepping out of the pedal because the pedal 3 still moves at a speed of 20 m/min.

[0016]

However, if the passenger rides on the pedal 3 that moves at an initial moving speed of 20 m/min, since it is close to the time period when a large number of passengers are expected to ride in, the operation of the timer 14 or switch 15 is performed according to h→i The order of →j→d increases the moving speed from 20 m/min to 40 m/min at high speed. The pedal 3 is running at a high speed, so the passenger may be uneasy about the action when stepping out of the pedal, thus causing a psychological burden.

[0017]

For this reason, when the pedal 3 is running at a speed of 20 m/min, if an instruction to increase the moving speed to 40 m/min is received, the speed will not be increased to 40 m/min immediately, but according to h→ In the order of i→m, the moving speed is first increased to an intermediate moving speed of, for example, 30 m/min between the initial moving speed of 20 m/min and the high-speed moving speed that should be increased to 40 m/min, And after running for a specified time at a speed of 30 m/min, increase the moving speed to a high-speed moving speed of 40 m/min in the order of m→n→e. Here, the predetermined time basically refers to the time obtained by adding a margin time to the time required to move by the pedal 3 on the entrance side to the exit side.

[0018]

By adopting the above-mentioned operation mode 3, when a passenger who rides on the pedal 3 moving at an initial moving speed of 20 m/min steps out from the pedal 3 whose speed is increased to 30 m/min, since the difference in moving speed is reduced to 10 m/min, So you won't feel too much movement speed difference. As a result, when stepping off the pedals, the occupant does not feel uneasy about the movement when stepping off the pedals, and thus does not impose a psychological burden. And, take the passenger of the pedal 3 that moves with the intermediate moving speed of 30 m/min after the speed-up, although it is to step out from the pedal 3 after the speed-up to 40 m/min, but because the moving speed difference is only 10 meters /min, so it is the same as the passenger who rides in at the initial moving speed of 20 m/min, and will not feel an excessive difference in moving speed.

[0019]

In the above, in the operation modes 2 and 3, the case of running at a low speed of 20 m/min in the energy-saving operation was explained, but the variable-speed electric passageway 1 installed in a facility with a long period of time when there are few passengers In the energy-saving operation, the low-speed operation mode of about 10 m/min can also be adopted.

[0020]

The operation mode 3 described above will be described below with reference to the processing flow in FIG. 3 .

[0021]

When the variable-speed electric channel 1 starts, it is judged whether it is an idle period (1). At this time, it is judged by presetting the speed change program started by the timer 14 of the control device 13, or by operating the switch 15. judge. If the starting time coincides with the peak period, immediately perform high-speed operation (6) with a moving speed of 40 m/min, and if it is an idle period, perform low-speed operation (2) with a moving speed of 20 m/min, that is, energy saving run. Then, in the low-speed operation, when approaching or reaching the peak period, the control device 13 judges whether the timer 14 or the changeover switch 15 have sent the speed-up instruction (3), if there is no speed-up instruction, then still maintain the low-speed operation (2 ), and if an acceleration command is received, increase the movement speed to the middle of 30 m/min between the high-speed movement speed of 40 m/min and the initial movement speed of 20 m/min Move speed for medium speed run (4). Then, it is judged by the control device 13 whether the operation with the intermediate moving speed has passed the prescribed time (5), if the prescribed operating time has not passed, then still maintain the middle speed operation (4), and if the prescribed running time has been passed time, then the speed of movement is increased to 40 m/min to carry out high-speed operation (6). Then, when running at high speed (6), it is judged by the control device 13 whether it has entered the idle period (7) again, if it has not entered the idle period, it still maintains the high-speed operation (6) of 40 meters per minute, and if it has Entered idle period, then carry out low-speed operation (8) with the initial moving speed of 20 meters/min. Then, during the running period, it is repeatedly judged whether the speed-up command (3) is received during the low-speed running (8), until finally the running is stopped.

[0022]

Fig. 4 is a variable-speed electric tunnel as a second embodiment of the variable-speed passenger conveyor according to the present invention.

[0023]

In the first implementation form shown in Figure 2, the speed-up command is output through the operation of the timer 14 or the switch 15, while in the second implementation form shown in Figure 4, the first implementation form is cancelled. Timer 14 and changeover switch 15 have adopted the method of detecting whether there is a passenger, and carrying out variable speed operation with the operation mode 3 shown in Fig. 1 .

[0024]

A specific structure will be described below with reference to FIG. 4 . In addition, the same parts as in FIG. 2 are denoted by the same symbols as in FIG. 2 , and detailed description thereof will be omitted.

[0025]

In order to output to the control device 13 an instruction signal for instructing the switching of running speeds, on the entrance-side guide grid 16 located at the entrance-side floor 4 side and the exit-side guide grid 17 located at the exit-side floor 5 side, along Passenger's advancing direction, the first passenger detection sensor 18A, the second passenger detection sensor 18B, the first step out passenger detection sensor 19A, the second step out passenger detection sensor 19B are set respectively, according to the signals detected by these sensors, The number of passengers or the moving speed of the passengers is detected by the passenger detection device 20 and the passenger detection device 21 , and the detection results are output to the control device 13 to switch the running speed.

[0026]

The operation of detecting the presence or absence of a passenger to perform variable-speed operation will be described below. First, after starting, the passenger is detected by the first passenger detection sensor 18A and the second passenger detection sensor 18B; low speed operation. During running stop or when running at a low speed of 10-20 m/min, if no passenger is detected, and from the time when the passenger passes through the first passenger detection sensor 18 to the time when the passenger passes through the second passenger detection sensor 18 When the interval time until the sensor 18B is long, it is judged to belong to the idle period. At this time, if it is in the stop state, it will run at a low speed of 20 m/min, and if it is in a state of running at a low speed of 10 to 20 m/min, it will still run at this moving speed.

[0027]

If a passenger enters the entrance-side guide grid 16 during a stop of operation or during low-speed operation, and the interval from when the passenger passes through the first passenger detection sensor 18A to when the passenger passes through the second passenger detection sensor 18B is When the time is shorter, it is judged to belong to the peak period, and immediately switches from a stop state or a low-speed operation state to a high-speed operation moving at a high speed of 40 m/min to transport passengers at a high speed.

[0028]

And, if there is a passenger who gets in during the low-speed operation of the idling period, if the interval time from when the passenger passes through the first passenger detection sensor 18A to when it passes through the second passenger detection sensor 18B is relatively short. For a short time, then of course it is judged to belong to the peak period, and a high-speed operation of 40 m/min is carried out. But as mentioned above, if the passengers who take in at a low speed of 20 m/min step out from the pedal at a high speed of 40 m/min after the acceleration, they may feel the excessive difference in moving speed. There is a sense of fear, so the control device 13 does not immediately perform a high-speed operation of 40 m/min after receiving the signal from the passenger detection device 20 indicating that it belongs to the peak period, but outputs to the inverter device 12 Switch to the switching signal of the medium speed operation of 30 meters per minute, and make the driving motor 9 speed up. Then, the medium-speed operation is maintained until the first step-out passenger detection sensor 19A and the second step-out passenger detection sensor 19B detect the passenger or the moving speed of the passenger in the low-speed operation. Afterwards, after the control device 13 receives the signal from the step-out passenger detection device 21, it outputs a change command to the inverter device 12 to switch to the high-speed operation of 40 m/min.

[0029]

In addition, it can also be arranged that if a passenger is first detected by the second step-out passenger detection sensor 19B and then detected by the first step-out passenger detection sensor 19A on the side of the step exit, the control device 13 judges the passenger. The passenger is a passenger who enters from the step exit, and the passenger is warned by voice.

[0030]

According to each embodiment described above, when switching from low-speed operation to high-speed operation, by performing medium-speed operation for a predetermined time, passengers who get in during low-speed operation will not feel excessive movement speed when stepping out from the pedals. Difference. And, although the subsequent passenger who gets in at the intermediate speed steps out from the pedal at the high speed, since the speed difference at this time is the same as the speed difference between the low-speed operation and the medium-speed operation, during the medium-speed operation Passengers who get in will not feel an excessive difference in moving speed when stepping out from the pedals.

[0031]

In addition, in the above-mentioned embodiments, the variable-speed passenger conveyor of the present invention has been described by taking the horizontally installed variable-speed electric tunnel as an example. However, it goes without saying that the present invention can also be applied to a variable-speed passenger conveyor and an escalator installed at an angle.
