Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
1. Configuration 1-1. Overview FIG. 1 is a schematic side view of an escalator according to the first embodiment. The escalator 1 in the present embodiment is an escalator of an automatic driving system that automatically starts a step when a user is detected. The escalator 1 is an example of a passenger conveyor.

The escalator 1 has an escalator body 10, a motor 20, an inverter 30, a control device 40, and the like.

The escalator main body 10 is installed in a state of being bridged between two floors F1 and F2 of the building. The escalator body 10 includes a plurality of steps 11 connected endlessly, a pair of left and right handrails 12, and a power transmission mechanism (not shown) that transmits the power of the motor 20 to the steps 11 and the handrail 12. , A floor plate 19 and the like that respectively configure the floor surfaces of the entrance 5 and the exit 6. The plurality of steps 11 and the handrail 12 are circularly driven by the power of the motor 20. In the escalator 1 according to the present embodiment, the floor F1 is provided with the entrance 5, and the floor F2 is provided with the exit 6. However, the present invention provides the floor F2 with the entrance 5. It is also applicable to the case where the floor F1 is provided with an exit.

The inverter 30 supplies AC power to the motor 20. The inverter 30 converts the frequency of the input AC power into a frequency according to the drive speed of the step 11, and outputs the frequency-converted AC power. The inverter 30 performs operations such as starting, stopping, and frequency conversion of electric power supply based on a command transmitted from the control device 40.

The motor 20 operates at a rotation speed that is proportional to the frequency of the AC power supplied from the inverter 30. The motor 20 is composed of, for example, an induction motor.

The control device 40 controls the operation of the escalator 1.

FIG. 2 and FIG. 3 are an enlarged side view and an enlarged plan view of the doorway 5 portion of the escalator 1 according to the first embodiment.

Each of the left and right hand rails 12 has a turn-back portion (nuel portion) 12n that is bent in an arc shape and turned back at both ends in the longitudinal direction. The escalator body 10 has a balustrade 18 that supports the handrail 12 so that it can travel. The inlets 16 are provided below the left and right folded portions 12n, respectively. The inlet 16 is an opening for introducing the handrail 12 into the handrail accommodating space below the balustrade 18 or discharging the handrail 12 from the handrail accommodating space to an external space, and is provided in the inlet guard 17 below the balustrade 18. There is.

The balustrade 18 is provided with a photoelectric sensor 61 in the vicinity of the folded portion 12n. The configuration and the like of the photoelectric sensor 61 will be described later.

FIG. 4 is a diagram showing an electrical configuration of the control device 40 of the escalator 1 according to the first embodiment.

The control device 40 has a control unit 41 and a storage unit 42. The control device 40 is configured using a programmable logic controller (PLC).

The storage unit 42 stores programs and various data. The programs include programs for realizing various functions of the control device 40 of the present embodiment.

The control unit 41 reads the program and the data from the storage unit 42, and performs arithmetic processing based on the read program and the data. As a result, various functions of the control device 40 are realized.

The control device 40 inputs a signal from the photoelectric sensor 61. The control device 40 controls the driving of the steps 11 by controlling the frequency of the electric power supplied from the inverter 30 to the motor 20 based on the signal input from the photoelectric sensor 61.

The photoelectric sensor 61 is an example of a user detection unit, and has a light projecting unit 61a and a light receiving unit 61b that are arranged to face each other. The photoelectric sensor 61 detects a user who passes a position Pd at a predetermined distance Lx from the tip of the comb 19a. In the present embodiment, the predetermined distance Lx is set to 912 mm, for example. It should be noted that the predetermined distance Lx may be longer or shorter than 912 mm.

Here, FIG. 10 is an enlarged side view of the entrance portion of the conventional automatic driving escalator. In the conventional JEAS-410B (standard revision 06-02), as shown in FIG. 10, regarding the automatic driving escalator, the distance between the photoelectric sensor for user detection provided on the photoelectric pole and the comb tip of the floor plate is set. It stipulates that the distance between the photoelectric sensor and the tip of the folded portion (nuel portion) should be 1700 mm or more, or 1000 mm or more. However, in an actual building, the above distance may not be ensured due to restrictions on the design of the building. In that case, JEAS-410B stipulates that the user should be allowed to accelerate while boarding, but the acceleration should be 0.1 m/s ² . The acceleration of 0.1 m/s ² is an acceleration that causes a gentle acceleration that does not cause the user who gets on the step to fall.

In response to this regulation, in the present embodiment, the distance between the tip of the folded-back portion 12n of the doorway 5 and the tip of the comb 19a shown in FIGS. 2 and 3 is the prescribed distance (1700 mm) prescribed by JEAS-410. It is set to a shorter distance (for example, 1000 mm). Further, the photoelectric sensor 61 is installed on the balustrade 18 in the vicinity of the folded portion 12n. According to such a configuration, automatic operation control can be performed without providing a photoelectric pole or an entrance prevention fence. Therefore, the aesthetic appearance of the escalator 1 and the building can be improved.

Here, when the user is detected by the photoelectric sensor 61, if the stopped step 11 is activated at an acceleration of 0.1 m/s ² , the user feels that something is wrong with the start of the step being very slow. There is a risk of having it. In order to suppress this, the following configuration is adopted in this embodiment.

FIG. 5 is a diagram illustrating speed control when the escalator is activated. In the present embodiment, when the inverter 30 does not supply AC power, that is, when the step 11 is not driven, when a signal indicating that the user has passed is received from the photoelectric sensor 61, control is performed. The device 40 causes the inverter 30 to output AC power having a predetermined frequency f1 lower than the rated frequency f2 when the step 11 is driven at the rated speed V2. Then, during the time T1, the frequency of the AC power to be output is increased at a predetermined frequency gradient from the predetermined frequency f1 to the rated frequency f2 so that the acceleration of the step 11 becomes an acceleration α1 of 0.1 m/s ² or less. Let The predetermined frequency gradient is (f2-f1)/T1.

Here, the predetermined frequency f1 is a frequency higher than 0 (zero) and lower than the rated frequency f2, and is, for example, 10 Hz. The speed V1 (predetermined speed V1) when the predetermined frequency f1 is 10 Hz is, for example, 5 m/min. The predetermined speed V1 is set to a speed at which a user who is about to get on the stopped escalator 1 can clearly recognize that the step 11 has started to move. The rated frequency f2 is, for example, 60 Hz. The speed V2 (rated speed V2) when the rated frequency f2 is 60 Hz is, for example, 30 m/min. The rated speed V2 may be set to a speed such as 20 m/min according to the installation environment. The acceleration α1 is an acceleration that satisfies the condition for ensuring the safety of the user who gets on the step 11, and is 0.1 m/s ² (a predetermined acceleration of 0.1 m/s ² or less) defined by JEAS. Is set as an example). The acceleration α1 may be an acceleration smaller than 0.1 m/s ² .

2. The automatic operation control of the escalator 1 by the operation control device 40 will be described in more detail with reference to a flowchart.

FIG. 6 is a flowchart illustrating a process of generating a driving command based on the detection result of the photoelectric sensor 61 by the control device 40. FIG. 7 is a flowchart illustrating automatic operation control of the escalator 1 by the control device 40. The processes according to the flowcharts of FIGS. 6 and 7 are executed in parallel.

The control device 40 determines whether the user is detected by the photoelectric sensor 61 of the doorway 5 (S11). For example, the control device 40 determines whether or not the signal output from the photoelectric sensor 61 of the doorway 5 indicates that the user is detected.

When the user is not detected (NO in S11), the control device 40 executes the determination in step S11 again.

When the user is detected (YES in S11), the control device 40 generates an operation command for the escalator 1 (S12).

Next, with reference to FIG. 7, automatic operation control of the escalator 1 by the control device 40 will be described.

The control device 40 determines whether or not a driving command has been generated (S21).

When the driving command is not generated (NO in S21), the control device 40 executes the determination of step S21 again.

When the driving command is generated (YES in S21), the control device 40 resets the driving time Tf to 0 (zero) (S22), and then starts measuring the driving time Tf (S23).

The control device 40 determines whether the escalator 1 is in operation (S24). The fact that the escalator 1 is in operation means that the steps 11 are driven and are moving.

If the escalator 1 is in operation (YES in S24), the control device 40 determines whether or not an operation command has been generated (S29).

When the driving command is generated (YES in S29), the control device 40 returns to the process of step S22 described above.

When the escalator 1 is not in operation in the determination in step S24 (NO in S24), the control device 40 causes the inverter 30 to drive the step 11 at the rated speed V2 as described above with reference to FIG. The AC power of a predetermined frequency f1 lower than the rated frequency f2 is output, and the frequency of the AC power to be output is from the predetermined frequency f1 to the rated frequency f2 during time T1, and the acceleration of the step 11 is 0.1 m/s ² or less. The acceleration is increased to a predetermined acceleration α1 (S25). That is, the step 11 is activated at the predetermined speed V1 corresponding to the predetermined frequency f1, and the speed of the step 11 is increased at the predetermined acceleration α1 to the rated speed V2 corresponding to the rated frequency f2. When AC power of a predetermined frequency f1 is supplied to the motor 20 from the inverter 30 and the step 11 starts moving, a small amount of time is required to start moving the step 11 due to inertia of the step 11 being stopped or the slip of the motor 20. Delay may occur, which is substantially negligible in the present invention. That is, the step 11 may immediately start moving at the predetermined speed V1 corresponding to the predetermined frequency f1.

After executing step S25 or when the driving command is not generated in the determination of step S29 (NO in S29), the control device 40 determines whether the driving time Tf is equal to or more than the predetermined driving time To (S26). ). The predetermined operation time To is a time obtained by adding a predetermined margin time to the movement time until the step 11 coming out from the tip of the comb 19a of the floor plate 19 of the entrance 5 is hidden by the floor plate 19 of the exit 6, that is, It is set to a time obtained by adding a predetermined margin time to the time from when the user gets on the escalator 1 until the user gets off the escalator 1. Here, the operation time Tf being equal to or longer than the predetermined operation time To is an example of a predetermined stop condition.

When the operating time Tf is not equal to or more than the predetermined operating time To (NO in S26), the control device 40 returns to the process of step S24.

When the operating time Tf is equal to or longer than the predetermined operating time To (YES in S26), the control device 40 determines whether the escalator 1 is stopped (S27). “During stop” means that the step 11 is not driven and is stopped.

When the escalator 1 is stopped (YES in S27), the control device 40 returns to the process of step S21.

When the escalator 1 is not stopped (NO in S27), the control device 40 stops the operation of the escalator 1 (S28). That is, the control device 40 causes the inverter 30 to stop supplying electric power to the motor 20 and stops driving the step 11.

Here, when a new user enters through the entrance 5 and a new driving command is generated in step S12 of FIG. 7 during driving at the rated speed V2, the control device 40 generates the driving command. (YES in S29), the operating time Tf is reset to 0 (zero) (S22), and the measuring of the operating time Tf is newly started (S23). Therefore, the determination regarding the predetermined driving time To in step S26 is performed based on the driving time Tf that is based on the time when a new driving command is generated. Therefore, the new user is escalator 1 (step 11). The operation at the rated speed V2 is continued until it gets off from.

3. Action of Escalator of this Embodiment The action of the escalator 1 of this embodiment will be described with reference to FIG. When the user is detected by the photoelectric sensor 61 of the doorway 5 while the escalator 1 is stopped, that is, the step 11 is stopped, the inverter 30 causes the motor 20 to drive the step 11 at the rated speed. AC power having a predetermined frequency f1 lower than the rated frequency f2 is supplied, and subsequently, the frequency of the AC power to be output is from the predetermined frequency f1 to the rated frequency f2, and the acceleration of the step 11 is 0.1 m/s ² or less. Is increased to a predetermined acceleration (α1). That is, the step 11 is started at the predetermined speed V1, and the speed of the step 11 increases to the rated speed V2 at the predetermined acceleration α1. Then, the step 11 is driven at the rated speed V2 until a predetermined stop condition is satisfied.

Here, the acceleration α1 is an acceleration that satisfies the condition for ensuring the safety of the user who gets on the step 11 as described above, and is set to the above-mentioned 0.1 m/s ² defined by JEAS. There is. In the present embodiment, when the user is detected, the steps 11 are immediately started at the predetermined speed V1 and are driven at the acceleration α1, so that when the user passes through the floor plate 19 and gets on the steps 11. The acceleration of the step 11 is already α1 (0.1 m/s ² ). Therefore, the safety of the user who gets on the step 11 can be appropriately maintained.

Further, the predetermined speed V1 is a speed at which a user who is about to get into the stopped escalator 1 can clearly recognize that the step 11 has begun to move, whereby the movement of the step can be started. It is possible to prevent the user from having an uncomfortable feeling of being extremely slow.

When time T1 elapses after the acceleration at the acceleration α1 is started, the acceleration is switched to zero, and the operation is performed at the rated speed V2.

As described above, according to the escalator 1 of the present embodiment, it is possible to prevent the user from feeling uncomfortable when the escalator 1 is automatically started.

(Embodiment 2)
The escalator 1 according to the second embodiment will be described. In the second embodiment, differences from the first embodiment will be mainly described.

FIG. 8 is an enlarged side view of the doorway 5 portion of the escalator 1 according to the second embodiment. FIG. 9 is an enlarged plan view of the doorway 5 portion of the escalator 1 according to the second embodiment.

In the present embodiment, a reflection type beam sensor 161 is provided as the user detection unit instead of the photoelectric sensor 61 of the first embodiment.

The reflective beam sensor 161 is arranged in each of the left and right inlet guards 17. Each reflective beam sensor 161 has a light projecting unit and a light receiving unit. The reflective beam sensor 161 detects a user who enters the detection area Rd. The detection region Rd has a width that is approximately the same as the distance (width) between the left and right hand rails 12, and is in the anti-riding direction from the tip position P1 of the folded-back portion 12n (the distance L1 from the tip of the comb 19a). Further, it extends to the position of the distance L2 (the position of the distance L2 from the tip of the comb 19a).

Other configurations are the same as those in the first embodiment.

According to the escalator 1 of the second embodiment, when the distance from the tip of the comb 19a to the tip position P1 of the folded portion 12n is the same as that of the first embodiment, the user who tries to get on the escalator 1 is In comparison with the first embodiment, it can be detected at a position farther from the comb 19a (a position at a distance L2 from the tip of the comb 19a). That is, the user who is about to board can be detected earlier than in the first embodiment. Therefore, the steps 11 can be activated at an earlier timing before getting on the user. Therefore, the user can visually confirm that the escalator 1 has started from a farther position, and can get on the board more smoothly.

To drive.

According to the escalator of the first and second embodiments, in the passenger conveyor of the automatic driving method, it is possible to prevent the user from feeling uncomfortable when the escalator is automatically started.

(2) In the escalator of the second embodiment,
The detection area (Rd) of the user detection unit (161) extends in the anti-boarding direction from the tips of the folded-back portions (12n) of the left and right handrails (12).

According to the escalator of the second embodiment, it is possible to detect a user trying to get on the escalator at an earlier timing and activate the step (11) at an earlier timing. Therefore, it becomes possible for the user to visually confirm that the escalator has started from a distant position and to get on smoothly.

(Embodiment 3)
In the first and second embodiments, when the control device 40 receives the signal indicating that the user has passed from the user detection unit (the photoelectric sensor 61 or the reflection type beam sensor 161) of the doorway 5, the escalator is turned on. An example in which the step 11 is driven by being activated has been described. However, the user detection unit similar to that of the first and second embodiments is also provided at the exit 6, and when the user detection unit of the exit 6 detects a user who tries to get in from the exit 6, the operation is performed. As in the first and second embodiments, the step 11 may be activated at a predetermined speed V1 corresponding to the predetermined frequency f1 and continuously driven for a time of, for example, several seconds. The driving direction of the steps 11 at this time is the same as that when the user is detected by the user detection unit (61 or 161) of the entrance 5. That is, the steps 11 are moved from the entrance 5 side toward the exit 6 side. As a result, the user who tries to get in from the exit 6 can recognize that he/she is currently at the exit 6 and is going to enter in the opposite direction. In particular, in the present embodiment, the step 11 immediately starts moving at the predetermined speed V1, so compared with the case where the step 11 starts to move gently at the acceleration α1 from the speed 0, the user who tries to get in from the exit 6 You can recognize more clearly that you are going in the opposite direction. Therefore, the reverse approach of the user can be suppressed more appropriately. In addition, when the user detecting unit of the exit 6 detects a user who tries to get in from the exit 6 while the step 11 is stopped, the step 11 is driven as described above and a buzzer or the like is operated. May be sounded to call the user's attention. As a result, it is possible to more appropriately suppress the reverse approach of the user.

(Embodiment 4)
In the first and second embodiments, the example in which the photoelectric sensor 61 or the reflection type beam sensor 161 is provided as the user detection unit at the entrance 5 has been described. However, both the photoelectric sensor 61 and the reflection type beam sensor 161 may be provided in the doorway 5. In this case, when the control device 40 receives a signal indicating that the user has passed from the reflection type beam sensor 161 of the doorway 5, the step 11 corresponds to the predetermined frequency f1 as in the first and second embodiments. It is started at a predetermined speed V1 and the speed is increased by acceleration α1. When the signal indicating that the user has passed is received from the photoelectric sensor 61 of the doorway 5 after the start-up, the step 11 is continuously driven for the predetermined operation time To similar to the first embodiment. If a signal indicating that the user has passed is not received from the photoelectric sensor 61 of the entrance 5 even after a lapse of a certain time after the start, the driving of the step 11 is stopped. The above-mentioned fixed time is a time shorter than the predetermined operation time To and is, for example, 20 seconds. With this configuration, similarly to the second embodiment, the step 11 can be driven at a timing earlier than that of the first embodiment, and only a person other than the elevator user has passed the front of the entrance 5. In such a case, it is possible to prevent the step 11 from being continuously driven for the predetermined operation time To. Therefore, energy saving can be improved as compared with the second embodiment.
