Description

[Technical field]

[0001] This specification relates to a people conveyor. [Background technology]

[0002] Conventionally, for example, a people conveyor includes steps that run to transport people, a load detection unit that detects the load transported by the steps, and a processing device that controls the running speed of the steps (for example, Patent Document 1). In the people conveyor according to Patent Document 1, the running speed of the steps is changed according to the load detected by the load detection unit.

[0003] However, for example, when an elderly person or a child tries to get on a step, if the step's running speed is fast, it may be difficult for the elderly person or a child to get on the step. Therefore, there is a demand to appropriately set the running speed of the step, taking into consideration not only the load that the step carries, but also, for example, the elderly person or a child using the person conveyor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions in order to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, some of the components may be omitted in order to facilitate understanding.

[0009] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] Hereinafter, one embodiment of the passenger conveyor will be described with reference to Figures 1 to 4. Note that the following embodiment is provided as an example to aid in understanding the configuration of the passenger conveyor, and is not intended to limit the configuration of the passenger conveyor.

[0011] As shown in Figure 1, a person conveyor 1 may include, for example, a structure 2 installed on a main body, a transport section 3 for transporting people (passengers), a pair of balustrade sections 4 (only one is shown in Figure 1) arranged to sandwich the transport section 3 in a first direction D1, a drive section 5 for driving the transport section 3 and the balustrade sections 4, and a processing device 6 for controlling the entire device.

[0012] In Figure 1, the first direction D1 is the first horizontal direction (also called the "width direction") D1 which is a direction parallel to the horizontal direction, the second direction D2 is the second horizontal direction (also called the "front-to-back direction") D2 which is a direction parallel to the horizontal direction and perpendicular to the first horizontal direction D1, and the third direction D3 is a vertical direction perpendicular to the first horizontal direction D1 and the second horizontal direction D2, and is the up-down direction D3.

[0013] The passenger conveyor 1 according to this embodiment is an escalator with a stepped tread surface for transporting passengers, but is not limited to such a configuration. For example, the passenger conveyor 1 may be a moving walkway with a flat tread surface for transporting passengers.

[0014] The transport unit 3 may, for example, as in this embodiment, include an endless annular running unit 3a that rotates and runs when driven by the drive unit 5, and a plurality of steps 3b that are connected to the running unit 3a to run together with the running unit 3a and have tread surfaces on which people stand in order to transport people. Although not particularly limited, the running unit 3a may be, for example, a roller chain.

[0015] Also, for example, the running portions 3a may be provided as a pair separated from each other in the first horizontal direction D1, and the steps 3b may be disposed between the pair of running portions 3a, 3a. The steps 3b may be connected to the respective running portions 3a so as to be rotatable about the first horizontal direction D1.

[0016] The driving unit 5 may include, for example, as in this embodiment, a rotating unit 5a around which a first end of the running unit 3a in the second horizontal direction D2 is wound and which rotates about an axis in the first horizontal direction D1, a supporting unit 5b that supports a second end of the running unit 3a in the second horizontal direction D2, and a driving source 5c that rotates the rotating unit 5a. As a result, the step 3b is reversed by the rotating unit 5a and also reversed by the supporting unit 5b.

[0017] Although not particularly limited, the rotating part 5a may be, for example, a sprocket. Furthermore, although not particularly limited, the support part 5b may be, for example, a guide member that guides the running part 3a to rotate in the reverse direction, or may be, for example, a rotating member (for example, a sprocket) around which the running part 3a is wound and which rotates about an axis in the first horizontal direction D1. Furthermore, although not particularly limited, the driving source 5c may be, for example, a motor.

[0018] The balustrade section 4 may include, for example, an endless circular handrail belt 4a that rotates and runs, a balustrade main body section 4b that supports the handrail belt 4a, and a cover section 4c that covers the lower part of the balustrade main body section 4b. Note that, for example, the handrail belt 4a may run by being driven by the drive section 5, and the running of the handrail belt 4a may be synchronized with the running of the step 3b.

[0019] The structure 2 may, for example, include a machine room 2a arranged at each end in the second horizontal direction D2 as in this embodiment. The passenger conveyor 1 may, for example, include a floor plate 1a attached to the structure 2 so as to cover the machine room 2a from above as in this embodiment. As a result, the floor plate 1a constitutes boarding and disembarking sections 1b arranged at each end in the second horizontal direction D2 of the conveying section 3 for getting on and off the conveying section 3.

[0020] As shown in Fig. 2, the people conveyor 1 is equipped with a load detection unit 7 that detects the load transported by the step 3b. The people conveyor 1 may also be equipped with a speed detection unit 8 that detects the running speed of the step 3b and a person detection unit 9 that detects people riding on the step 3b, as in this embodiment. The driving unit 5 may also be equipped with a change unit 5d that changes the running speed of the step 3b, as in this embodiment.

[0021] The change unit 5d is not particularly limited, but may be, for example, an inverter that changes the frequency of the power supplied to the motor that is the driving source 5c in order to change the rotational speed of the rotating unit 5a, or may be, for example, a gear device that switches the gear that meshes with the rotating unit 5a in order to change the rotational speed of the rotating unit 5a.

[0022] The speed detection unit 8 is not particularly limited, and may be, for example, a sensor (e.g., a proximity sensor, a photoelectric sensor) that detects the teeth on the outer periphery of the rotating part 5a, or may be, for example, a sensor (e.g., an encoder) that detects the rotation of the rotating part 5a, or may be, for example, a sensor (e.g., an encoder) that detects the rotation of a roller that rotates by contacting the step 3b.

[0023] The human detection unit 9 may detect a person at the boarding and disembarking section 1b, for example, to detect a person getting on the person conveyor 1 (step 3b). The human detection unit 9 is not particularly limited, and may be, for example, a photoelectric sensor, or may be, for example, a camera that captures images from above or the side, or may be, for example, a load cell that detects the weight of a person from below, or may be, for example, an inverter or a wattmeter that detects the load (for example, torque value, power value) of the motor that is the driving source 5c.

[0024] The configuration of the load detection unit 7 is not particularly limited. For example, the load detection unit 7 may be configured by an inverter or a power meter that detects the torque value or power value of the driving source 5c, and the speed detection unit 8. Specifically, for example, when the traveling speed in step 3b is the same, the power value of the driving source 5c increases as the load transported in step 3b increases. Therefore, the processing device 6 may calculate the load transported in step 3b (for example, a load rate relative to a rated load) based on the power value of the driving source 5c and the speed of the speed detection unit 8.

[0025] Also, for example, the load detection unit 7 may be configured with a human detection unit 9. For example, the more people who get on step 3b, the greater the load to be transported on step 3b. Therefore, the processing device 6 may calculate the load to be transported on step 3b (for example, a load rate relative to a rated load) based on detection by the human detection unit 9 (for example, a cumulative detection time in a predetermined time, a number of detections in a predetermined time, etc.).

[0026] Furthermore, the passenger conveyor 1 may be equipped with an input unit 10 to which various information is input, and an output unit 11 to which various information is output, as in the present embodiment. Although not particularly limited, for example, the information input to the input unit 10 may be operation mode information (manual operation selection, automatic operation selection), operation instruction information (operation start instruction, operation stop instruction), step travel direction information (upper side conveyance selection, lower side conveyance selection), step travel speed information (rated speed operation selection, low speed operation selection), etc.

[0027] Also, although not limited to, the input unit 10 may be, for example, a switch (push button switch, select switch, etc.), a touch panel, etc. Also, although not limited to, the output unit 11 may be, for example, a display unit that displays information (for example, an electronic bulletin board, an indicator light), a sound generating unit that emits information as sound (for example, a buzzer, a speaker), a signal output unit that outputs a signal to the outside (for example, a central monitoring panel, etc.), etc.

[0028] The processing device 6 may include, for example, as in this embodiment, an acquisition unit 12 that acquires each piece of information (data) from each unit 7 to 10, a storage unit 13 that stores each piece of information, a calculation unit 14 that calculates each piece of information, and a control unit 15 that controls each unit 5, 11. The processing device 6 may be a computer that includes, for example, a processor such as a CPU and an MPU (for example, the calculation unit 14, the control unit 15), memories such as a ROM and a RAM (for example, the acquisition unit 12, the storage unit 13), various interfaces, and the like.

[0029] As a result, the processor executes the program stored in the memory, and the software and hardware work together to realize the units 12, 13, 14, and 15 of the processing device 6. The processing device 6 may be configured, for example, with a software circuit, or may be configured, for example, with a hardware circuit, or may be configured, for example, with a combination of a software circuit and a hardware circuit.

[0030] The processing device 6 may be configured, for example, as one device, or may be configured, for example, as multiple devices that can communicate with each other. Specifically, the units 12, 13, 14, and 15 of the processing device 6 may be provided, for example, in one device, or may be provided, for example, distributed across multiple devices that can communicate with each other.

[0031] The calculation unit 14 may, for example, as in this embodiment, include a presence determination unit 14a that determines the presence or absence of a person on the people conveyor 1 based on detection by the person detection unit 9, and a load determination unit 14b that determines the load being conveyed by the step 3b based on detection by the load detection unit 7. The control unit 15 may, for example, as in this embodiment, include a drive control unit 15a that controls the change unit 5d in order to control the running speed of the step 3b based on detection by the speed detection unit 8, and an output control unit 15b that controls the output unit 11.

[0032] The configuration of the passenger conveyor 1 according to this embodiment is as described above, and next, a method for controlling the running speed of step 3b according to this embodiment will be described. Note that the following method is an example to help understand the method for controlling the running speed of step 3b, and does not limit the method for controlling the running speed of step 3b.

[0033] <First Operation Control> First, a method of controlling the travel speed in step 3b when the processor 6 is executing the first operational control will be described.

[0034] In the first operation control, when the load determination unit 14b determines that the load detected by the load detection unit 7 is equal to or greater than the first set value, the drive control unit 15a sets the maximum running speed of step 3b as the first running speed. Although not particularly limited, the running speed of step 3b may be, for example, constant at the first running speed (including not only the same speed but also approximately the same speed with an error of ±10%), or may be, for example, a speed within a predetermined range with the first running speed as the maximum speed.

[0035] Furthermore, when the load determination unit 14b determines that the load detected by the load detection unit 7 is less than the first set value, the drive control unit 15a sets the maximum traveling speed of step 3b to a second operating speed that is slower than the first operating speed. Although not particularly limited, the traveling speed of step 3b may be, for example, constant at the second operating speed (including not only the same but also approximately the same with an error of ±10%), or may be, for example, a speed within a predetermined range with the second operating speed as the maximum speed.

[0036] Also, although not particularly limited, the first set value may be, for example, a value corresponding to a load factor of 15% to 25% of the rated load. Also, although not particularly limited, the first operating speed may be, for example, 25 m / min to 30 m / min, and the second operating speed may be, for example, 20 m / min to 25 m / min.

[0037] The presence determination unit 14a determines the presence or absence of a person based on the detection by the person detection unit 9. Although not particularly limited, for example, when the person detection unit 9 detects a person, the presence determination unit 14a may determine that a person is present, and for example, when a set time (for example, the time for step 3b to travel a distance of 1 / 2 revolution + 30 seconds) has elapsed after the person detection unit 9 last detected a person, the presence determination unit 14a may determine that no person is present.

[0038] When the presence determination unit 14a determines that a person is present, the drive control unit 15a sets the driving state (high-speed driving state) in which the traveling speed in step 3b is the driving speed (first driving speed or second driving speed). On the other hand, when the presence determination unit 14a determines that no person is present, the drive control unit 15a sets the driving state in which the traveling speed in step 3b is a standby speed slower than the second driving speed (slower than a third driving speed described later). Although not particularly limited, the standby speed may be, for example, zero (0 m / sec) to 10 m / min.

[0039] In this embodiment, when the presence determination unit 14a determines that no person is present, the running speed in step 3b becomes the standby speed, but the present invention is not limited to this configuration. For example, the running speed in step 3b may be the driving speed (first driving speed or second driving speed) regardless of the detection by the person detection unit 9. That is, the drive control unit 15a may be configured to set the vehicle in a driving state (high-speed driving state) regardless of the detection by the person detection unit 9.

[0040] <Second Operation Control> Next, a method of controlling the travel speed in step 3b when the processor 6 is executing the second operational control will be described.

[0041] In the second operation control, regardless of the load detected by the load detection unit 7, the drive control unit 15a sets the maximum running speed in step 3b to a third running speed that is equal to or lower than the second running speed. Although not particularly limited, the running speed in step 3b may be constant at the third running speed (including not only the same speed but also approximately the same speed with an error of ±10%), or may be a speed within a predetermined range with the third running speed as the maximum speed. Although not particularly limited, the third running speed may be 15 m / min to 20 m / min. The third running speed may be slower than the second running speed, for example, as in this embodiment.

[0042] The presence determination unit 14a determines the presence or absence of a person based on the detection by the person detection unit 9. Although not particularly limited, for example, when the person detection unit 9 detects a person, the presence determination unit 14a may determine that a person is present, and for example, when a set time (for example, the time for step 3b to travel a distance of 1 / 2 revolution + 30 seconds) has elapsed after the person detection unit 9 last detected a person, the presence determination unit 14a may determine that no person is present.

[0043] When the presence determination unit 14a determines that a person is present, the drive control unit 15a sets the driving state (low-speed driving state) in which the traveling speed in step 3b is the driving speed (third driving speed). On the other hand, when the presence determination unit 14a determines that no person is present, the drive control unit 15a sets the driving state in which the traveling speed in step 3b is a standby speed that is slower than the third driving speed. The standby speed may be, for example, zero (0 m / sec) to 10 m / min, without being particularly limited thereto.

[0044] In this embodiment, when the presence determination unit 14a determines that no person is present, the running speed in step 3b becomes the standby speed, but the present invention is not limited to this configuration. For example, the running speed in step 3b may be the driving speed (third driving speed) regardless of the detection by the person detection unit 9. That is, the drive control unit 15a may be configured to set the vehicle in a driving state (low-speed driving state) regardless of the detection by the person detection unit 9.

[0045] <Operation switching control> Next, the operation switching control in which the processing device 6 switches between the first operation control and the second operation control will be described with reference to FIGS.

[0046] 3 and 4, for example, when operation start information is input to the input unit 10 at the start time (around 6:00 in FIG. 4) ("Y" in S1), the processing device 6 executes the first operation control (S2). Then, the processing device 6 executes the first operation control (S2) until the predetermined first time (10:00 in FIG. 4) ("N" in S3).

[0047] Thereafter, when the first time arrives ("Y" in S3), if the load determining unit 14b determines that the load detected by the load detecting unit 7 is less than the first set value ("Y" in S4), the processing device 6 immediately switches from the first operation control to the second operation control (S5). This makes it possible to execute the second operation control during the time period when, for example, elderly people and children often use the people conveyor 1.

[0048] On the other hand, when the first time arrives ("Y" in S3), if the load determination unit 14b determines that the load detected by the load detection unit 7 is equal to or greater than the first set value ("N" in S4), the processing device 6 continues the first operational control (S2). As a result, when the load to be transported in step 3b is large, the travel speed in step 3b can be set to a speed according to the load. Therefore, for example, it is possible to prevent congestion of people at the boarding and disembarking section 1b.

[0049] After that, when the load determining unit 14b determines that the load detected by the load detecting unit 7 is less than the first set value ("Y" in S4), the processing device 6 switches from the first operation control to the second operation control (S5). As a result, the second operation control is executed after the load to be transported in step 3b is reduced.

[0050] Furthermore, when the predetermined second time (4:00 p.m. in FIG. 4) arrives ("Y" in S6), if the load determination unit 14b determines that the load detected by the load detection unit 7 is equal to or greater than the first set value ("Y" in S7), the processing device 6 immediately switches from the second operation control to the first operation control. This makes it possible to set the travel speed in step 3b to a speed appropriate to the load during the time period when the load being transported in step 3b is high.

[0051] On the other hand, when the second time arrives ("Y" in S6), if the load determining unit 14b determines that the load detected by the load detecting unit 7 is less than the first set value ("N" in S7), the processing device 6 continues the second operation control (S5). This makes it possible to prevent the travel speed of step 3b from becoming faster than necessary for the load being transported in step 3b, for example.

[0052] After that, when the load determining unit 14b determines that the load detected by the load detecting unit 7 is equal to or greater than the first set value ("Y" in S7), the processing device 6 switches from the second operation control to the first operation control (S8). This allows the travel speed in step 3b to be set to a speed according to the load after the load being transported in step 3b increases. Then, for example, when information to stop operation is input to the input unit 10 at the stop time (around 10 p.m. in FIG. 4) ("Y" in S9), the processing device 6 stops operation.

[0053] Meanwhile, when the second operation control is being executed (S5), if the load determination unit 14b determines that the load detected by the load detection unit 7 is equal to or greater than a second set value that is greater than the first set value ("Y" in S10) before the second time arrives ("N" in S6), the processing device 6 switches from the second operation control to the first operation control (S11).

[0054] As a result, even if the second operation control is being executed, the first operation control is executed when the load to be transported in step 3b is large. Therefore, since the travel speed in step 3b can be set to a speed according to the load, for example, congestion of people at boarding and disembarking section 1b can be suppressed.

[0055] After that, when the load determining unit 14b determines that the load detected by the load detecting unit 7 is less than the second set value ("Y" in S12), the processing device 6 switches from the first operation control to the second operation control (S5). Although not particularly limited, the second set value may be, for example, a value corresponding to a load factor of 40% to 50% of the rated load.

[0056] In this way, the processing device 6 switches between the first operating control and the second operating control, so that the first operating control can set the running speed of the step 3b to a speed according to the load, while the second operating control can set the running speed of the step 3b to a speed that makes it easy for elderly people and children to ride on the step 3b, regardless of the load.

[0057] Therefore, the running speed in step 3b can be appropriately adjusted. In order to prevent the running speed in step 3b from changing suddenly, the acceleration / deceleration of the running speed in step 3b is not particularly limited, but may be set to, for example, 0.1 m / (sec) 2 It is preferable that:

[0058] [1] From the above, the passenger conveyor 1, as in this embodiment, Step 3b of traveling to transport the person; A load detection unit 7 that detects the load conveyed in step 3b; A processing device 6 for controlling the travel speed in step 3b, The processing device 6 switches between a first operation control and a second operation control, The first operation control sets the maximum traveling speed of the step 3b to a first operating speed when the load detected by the load detection unit 7 is equal to or greater than a first set value, and sets the maximum traveling speed of the step 3b to a second operating speed slower than the first operating speed when the load detected by the load detection unit 7 is less than the first set value; The second operation control sets the maximum traveling speed of the step 3b to a third operation speed that is equal to or lower than the second operation speed, regardless of the load detected by the load detection unit 7. This configuration is preferred.

[0059] According to this configuration, in the first operation control, when the load detected by the load detection unit 7 is equal to or greater than the first set value, the maximum running speed in step 3b is set to the first running speed, whereas when the load detected by the load detection unit 7 is less than the first set value, the maximum running speed in step 3b is set to the second running speed which is slower than the first running speed. This allows the first operation control to set the running speed in step 3b to a speed according to the load.

[0060] On the other hand, the first operation control and the second operation control are switched, and in the second operation control, the maximum running speed of the step 3b is set to the third running speed, which is equal to or lower than the second running speed, regardless of the load detected by the load detection unit 7. This allows the running speed of the step 3b to be set to a speed at which elderly people and children can easily ride on the step 3b, regardless of the load. Therefore, the running speed of the step 3b can be set appropriately.

[0061] [2] In addition, in the passenger conveyor 1 described above in [1], as in this embodiment, The processing device 6 switches between the first operational control and the second operational control at a predetermined time. This configuration is preferred.

[0062] According to this configuration, since the first operation control and the second operation control are switched at a preset time, it is possible to set a time period during which the first operation control is executed and a time period during which the second operation control is executed. This makes it possible to set a time period during which the travel speed of step 3b is set to a speed according to the load, and a time period during which the travel speed of step 3b is set to a speed that is easy for elderly people and children to ride on step 3b, regardless of the load.

[0063] [3] In addition, in the passenger conveyor 1 described in [2] above, as in this embodiment, The processing device 6 switches from the first operation control to the second operation control when the load detected by the load detection unit 7 after a predetermined first time has arrived is less than the first set value. This configuration is preferred.

[0064] According to this configuration, if the load is less than the first set value at the first predefined time, the first operational control is immediately switched to the second operational control. On the other hand, if the load is equal to or greater than the first set value at the first predefined time, the first operational control is continued, and thereafter, if the load becomes less than the first set value, the first operational control is switched to the second operational control.

[0065] [4] In addition, in the passenger conveyor 1 of [2] or [3] above, as in this embodiment, The processing device 6 switches from the second operation control to the first operation control when the load detected by the load detection unit 7 after a second predetermined time has arrived is equal to or greater than the first set value. This configuration is preferred.

[0066] According to this configuration, if the load is equal to or greater than the first set value at the second predefined time, the second operational control is immediately switched to the first operational control. On the other hand, if the load is less than the first set value at the second predefined time, the second operational control is continued, and thereafter, if the load becomes equal to or greater than the first set value, the second operational control is switched to the first operational control.

[0067] [5] In addition, in any one of the passenger conveyors 1 described above in [1] to [4], as in this embodiment, When the load detected by the load detection unit 7 becomes equal to or greater than a second set value that is greater than the first set value while the second operation control is being executed, the processing device 6 switches from the second operation control to the first operation control. The following configuration is also possible.

[0068] According to this configuration, when the second operational control is being executed, the maximum traveling speed in step 3b is set to the third operational speed regardless of the load. On the other hand, when the second operational control is being executed, if the load becomes equal to or greater than a second set value that is greater than the first set value, the second operational control is switched to the first operational control.

[0069] The passenger conveyor 1 is not limited to the configuration of the embodiment described above, nor is it limited to the above-mentioned effects. Furthermore, the passenger conveyor 1 can be modified in various ways without departing from the spirit of the present invention. For example, it is possible to select one or more of the configurations and methods of the various modified examples described below and adopt them in the configurations and methods of the embodiment described above.

[0070] (A) In the passenger conveyor 1 according to the above embodiment, the number of times the first operation control is switched to the second operation control is one in a day. However, the passenger conveyor 1 is not limited to such a configuration. For example, the number of times the first operation control is switched to the second operation control may be multiple in a day. Although not particularly limited, for example, as shown in FIG. 5, the number of times the first operation control is switched to the second operation control may be two in a day.

[0071] (B) In addition, in the passenger conveyor 1 according to the above embodiment, the number of times per day the second operation control is switched to the first operation control is one. However, the passenger conveyor 1 is not limited to such a configuration. For example, the number of times per day the second operation control is switched to the first operation control may be multiple. Although not particularly limited, for example, as shown in FIG. 5, the number of times per day the second operation control is switched to the first operation control may be two.

[0072] (C) In addition, in the passenger conveyor 1 according to the above embodiment, the processing device 6 is configured to switch between the first operation control and the second operation control at a predetermined time. However, the passenger conveyor 1 is not limited to such a configuration.

[0073] For example, the processing device 6 may be configured to switch between the first operation control and the second operation control when operation switching instruction information is input to the input unit 10. Also, for example, the processing device 6 may be configured to switch between the first operation control and the second operation control based on the weather (for example, detection by a rain detection unit that detects rain, detection by an illuminance detection unit that detects illuminance, detection by a temperature detection unit that detects temperature, etc.).

[0074] Also, for example, the first operational control may be performed when the load detected by the load detection unit 7 is maintained at or above a first predetermined value for a first predetermined time. Although not particularly limited, for example, the first predetermined value may be a value corresponding to a load factor of 40% to 50% of the rated load, and the first predetermined time may be, for example, 30 minutes to 60 minutes.

[0075] Also, for example, the second operation control may be performed when the load detected by the load detection unit 7 is maintained to be less than a second predetermined value for a second predetermined time. Although not particularly limited, the second predetermined value may be a value smaller than the first predetermined value, for example, a value corresponding to a load factor of 5% to 10% of the rated load, and the second predetermined time may be, for example, 10 minutes to 30 minutes.

[0076] (D) In ​​addition, in the passenger conveyor 1 according to the above embodiment, the processing device 6 is configured to switch from the first operation control to the second operation control when the load detected by the load detection unit 7 after the first predetermined time is reached is less than the first set value. However, the passenger conveyor 1 is not limited to such a configuration. For example, the processing device 6 may be configured to switch from the first operation control to the second operation control when the first predetermined time is reached, regardless of the load detected by the load detection unit 7.

[0077] (E) In addition, in the passenger conveyor 1 according to the above embodiment, the processing device 6 is configured to switch from the second operation control to the first operation control when the load detected by the load detection unit 7 after the second predetermined time is reached is equal to or greater than the first set value. However, the passenger conveyor 1 is not limited to such a configuration. For example, the processing device 6 may be configured to switch from the second operation control to the first operation control when the second predetermined time is reached, regardless of the load detected by the load detection unit 7.

[0078] (F) In addition, in the passenger conveyor 1 according to the above embodiment, the processing device 6 is configured to switch from the second operation control to the first operation control when the load detected by the load detection unit 7 becomes equal to or greater than a second set value that is greater than the first set value while the second operation control is being executed. However, the passenger conveyor 1 is not limited to such a configuration. For example, the processing device 6 may be configured to maintain the second operation control regardless of the load detected by the load detection unit 7 while the second operation control is being executed.

[0079] (G) In addition, in the passenger conveyor 1 according to the above embodiment, the third operating speed is slower than the second operating speed. However, the passenger conveyor 1 is not limited to such a configuration. For example, the third operating speed may be the same as the second operating speed.

[0080] (H) For example, the order of execution of each process, such as operations, procedures, steps, and stages, in the methods and apparatuses shown in the claims, specifications, and drawings, may be arbitrary, so long as the result of a previous process is not used in a subsequent process. For example, even if the description uses "first," "next," etc. for convenience, it does not mean that the processes must be executed in that order. [Explanation of symbols]
