Description

[Technical Field]

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

[0002] Conventionally, for example, a people conveyor has been equipped with a circular running part that rotates and runs, a support part that supports a first lateral end of the running part, and a detection part that detects movement of the support part (for example, Patent Document 1). The detection part detects that the support part has moved to a first movement position that is a first distance away from the initial position, and that the support part has moved to a second movement position that is a second distance away from the initial position that is smaller than the first distance.

[0003] In the passenger conveyor of Patent Document 1, the detection unit is composed of a single sensor. As a result, the position of the detection unit is fixed, and the first movement position is set, and accordingly, the second movement position is also necessarily set. Therefore, the first movement position and the second movement position cannot be set separately. [Prior art documents] [Patent documents]

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

[0009] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish 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. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] An embodiment of a passenger conveyor will be described below with reference to Figures 1 to 7. 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, the passenger 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 the second direction D2, a drive section 5 for driving the transport section 3 and the balustrade sections 4, and a processing section 6 for controlling the entire device.

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

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

[0014] The transport unit 3 includes a circular running unit 7 that rotates and runs, and a plurality of steps 8 connected to the running unit 7. For example, as in this embodiment, the running unit 7 may be configured to rotate and run by being driven by the drive unit 5, and the plurality of steps 8 may be connected to the running unit 7 and run together with the running unit 7. In this way, the steps 8 run with people on board.

[0015] The drive unit 5 may include, for example, as in this embodiment, a rotation unit 5a on which a first end of the traveling unit 7 in the first horizontal direction D1 is hooked and which rotates about an axis in the second horizontal direction D2, a drive source 5b that rotates the rotation unit 5a, and a braking unit 5c that brakes the rotation of the rotation unit 5a. The drive unit 5 also includes a support unit 9 on which a second end of the traveling unit 7 in the first horizontal direction D1 is hooked and which supports the second end of the traveling unit 7 in the first horizontal direction D1.

[0016] The step 8 is reversed by the rotating unit 5a and also reversed by the support unit 9. Although not particularly limited, the rotating unit 5a may be, for example, a sprocket (drive sprocket). Furthermore, although not particularly limited, the drive source 5b may be, for example, a motor and inverter. Furthermore, although not particularly limited, the braking unit 5c may be, for example, a brake.

[0017] The balustrade section 4 may, for example, as in this embodiment, comprise a 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 running sections 7 and steps 8.

[0018] The structural body 2 may include, for example, machine rooms 2a arranged at each end in the second horizontal direction D2, as in this embodiment. The structural body 2 may also have, for example, a truss structure or a girder structure made up of a plurality of frames 2b to 2e (see FIGS. 3 and 4).

[0019] The passenger conveyor 1 may, for example, include a floor plate 10 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 10 constitutes boarding and disembarking sections 1a located at each end of the transport section 3 in the first horizontal direction D1 for passengers to get on and off the steps 8 of the transport section 3.

[0020] 2, for example, a pair of running sections 7 may be provided spaced apart in the second horizontal direction D2, and multiple steps 8 may be disposed between the pair of running sections 7, 7. Also, for example, as in this embodiment, the transport unit 3 may be provided with a connecting shaft 3a connecting the pair of running sections 7, 7, and the steps 8 may be rotatably coupled to the connecting shaft 3a. As a result, the steps 8 are connected to each running section 7 so as to be rotatable about an axis in the second horizontal direction D2.

[0021] For example, as in this embodiment, the step 8 may include a step roller 8a that can rotate about an axis in the second horizontal direction D2, and a step body 8b that is rotatably connected to the step roller 8a. For example, as in this embodiment, the step body 8b may include a tread portion 8c on which a person stands, a rise portion 8d that is formed in a curved shape, and a pivot portion 8e that is rotatably connected to the connection shaft 3a.

[0022] The running section 7 is not particularly limited, but may include, for example, as in the present embodiment, a chain 7a formed in a ring shape and running rollers 7b, 7c rotatably connected to the chain 7a around an axis in the second transverse direction D2. That is, the running section 7 may be a roller chain, for example, as in the present embodiment. Also, for example, as in the present embodiment, the first running roller 7b among the plurality of running rollers may be rotatably connected to an end of the connecting shaft 3a, and the second running roller 7c among the plurality of running rollers may be arranged away from the connecting shaft 3a.

[0023] For example, as in this embodiment, a pair of support parts 9 may be provided so as to sandwich the step 8 in the second horizontal direction D2. Note that Fig. 3 only shows the support part 9 on one side (the side opposite to the arrow direction of the second horizontal direction D2). Also, Fig. 3 shows only the first running roller 7b, and does not show the second running roller 7c. Also, in Fig. 3, the structure 2, the chain 7a of the running part 7, and the floor plate 10 are shown by two-dot chain lines.

[0024] 3, the support portion 9 may include, for example, a support main body portion 9a, a travel guide portion 9b that guides the travel portion 7, and a roller guide portion (not shown) that guides the step rollers 8a (see FIG. 2) of the step 8. As a result, the travel portion 7 is guided by the travel guide portion 9b so as to turn back its travel direction, and the step 8 is guided by the roller guide portion so as to turn back its travel direction.

[0025] The support body 9a may be formed in a plate shape extending in the up-down direction D3 and the first horizontal direction D1, as in the present embodiment. The travel guide 9b may be a plate-shaped rail fixed to the support body 9a, as in the present embodiment. However, the present embodiment is not limited to this configuration, and the support 9 may be, for example, a sprocket (driven sprocket) around which the travel part 7 is wound and which can rotate about an axis in the second horizontal direction D2.

[0026] For example, as in the present embodiment, the structure 2 may include an upper frame 2b and a lower frame 2c extending in the first horizontal direction D1, a vertical frame 2d extending in the vertical direction D3 and connecting the upper frame 2b and the lower frame 2c, and a horizontal frame 2e extending in the horizontal directions D1 and D2 and connecting the frames 2b to 2d. Although not particularly limited, the structure 2 may include, for example, a diagonal frame extending at an angle and connecting the frames 2b to 2e.

[0027] The people conveyor 1 may, for example, as in this embodiment, be equipped with a movement mechanism 11 that enables the support portion 9 to move in the first lateral direction D1 relative to the structure 2. This allows the support portion 9 to move in the first lateral direction D1 relative to the structure 2.

[0028] The moving mechanism 11 includes an elongated body 11a fixed to the support unit 9 and extending in the first horizontal direction D1, and a tension applying unit 11b that applies a force to the running unit 7 to apply tension to the running unit 7. The moving mechanism 11 may also include, for example, a support roller 11c connected to the support unit 9, and a support guide unit 11d fixed to the structure 2 and extending in the first horizontal direction D1 to guide the support roller 11c in the first horizontal direction D1, as in the present embodiment.

[0029] The tension applying portion 11b may, for example, as in this embodiment, include an elastic portion 11e that elastically deforms in the first lateral direction D1, a first retaining material 11f that is fixed to the elongated body 11a and holds a first end of the elastic portion 11e, and a second retaining material 11g that is fixed to the structure 2 and holds a second end of the elastic portion 11e.

[0030] As a result, elastic deformation of elastic portion 11e in first lateral direction D1 applies an elastic restoring force in the first lateral direction D1 to support portion 9 via elongated body 11a. Therefore, tension can be applied to running portion 7 by tension applying portion 11b. Although not particularly limited, elastic portion 11e may be, for example, a helical spring into which elongated body 11a is inserted, as in this embodiment.

[0031] 3 and 4, the passenger conveyor 1 is equipped with a first detection unit 12 that detects that the support member 9 has moved from its initial position to a first movement position that is separated in the first horizontal direction D1 by a first distance W1 (see FIG. 5), and a second detection unit 13 that detects that the support member 9 has moved from its initial position to a second movement position that is separated in the first horizontal direction D1 by a second distance W2 (see FIG. 6) that is smaller than the first distance W1. The passenger conveyor 1 also is equipped with a first detectable member 14 that is detected by the first detection unit 12, and a second detectable member 15 that is detected by the second detection unit 13.

[0032] The first detection unit 12 includes a first detection main body 12a fixed to the structure 2 and a first mover 12b movable relative to the first detection main body 12a. When the first mover 12b comes into contact with the first detected portion 14, the first mover 12b moves from the non-detection position to the detection position, and the first detection unit 12 detects that the support portion 9 has moved to the first movement position. Note that the first detection unit 12 may be disposed inside the machine room 2a, for example, as in this embodiment.

[0033] The second detection unit 13 includes a second detection main body 13a fixed to the structure 2 and a second mover 13b movable relative to the second detection main body 13a. When the second mover 13b comes into contact with the second detected portion 15, the second mover 13b moves from the non-detection position to the detection position, and the second detection unit 13 detects that the support portion 9 has moved to the second movement position. Note that the second detection unit 13 may be disposed inside the machine room 2a, for example, as in this embodiment.

[0034] In the first detection unit 12, for example, as shown in Fig. 5(a), when the support unit 9 is located in the initial position, the first mover 12b is away from the first detected portion 14 and is located in the non-detection position. Then, as shown in Fig. 5(b), when the support unit 9 (see Fig. 3) moves to a first movement position that is away from the initial position by a first distance W1, the first mover 12b moves from the non-detection position to the detection position. This allows the first detection unit 12 to detect that the support unit 9 has moved to the first movement position.

[0035] Thereafter, for example, as shown in Fig. 5(c), even if the support portion 9 returns to the initial position, the first movable element 12b is held at the detection position. Then, for example, by operating the first detection portion 12, the first movable element 12b returns from the detection position to the non-detection position as shown in Fig. 5(a).

[0036] In this way, in the first detection unit 12, the first movable element 12b is held at the detection position by moving to the detection position, and is returned from the detection position to the non-detection position by being operated. Note that the first detection unit 12 may include, for example, as in this embodiment, a holding unit (not shown) that holds the first movable element 12b at the detection position, and an operating unit (for example, a push switch) 12c that is operated to return the first movable element 12b from the detection position to the non-detection position.

[0037] In the second detecting section 13, for example, as shown in Fig. 6(a), when the support section 9 (see Fig. 3) is located in the initial position, the second movable element 13b is away from the second detected section 15 and is located in the non-detection position. Then, as shown in Fig. 6(b), when the support section 9 moves to a second movement position that is away from the initial position by a second distance W2, the second movable element 13b moves from the non-detection position to the detection position.

[0038] As a result, the second detection unit 13 detects that the support unit 9 has moved to the second movement position. After that, for example, as shown in Fig. 5(c), when the support unit 9 returns to the initial position, the second movable element 13b automatically returns from the detection position to the non-detection position.

[0039] In this way, second movable element 13b automatically returns from the detection position to the non-detection position in second detection unit 13. Note that second detection unit 13 may include, for example, a return unit (not shown) that applies force to second movable element 13b to return second movable element 13b from the detection position to the non-detection position, as in this embodiment.

[0040] 3 and 4, the people conveyor 1 may, for example, as in this embodiment, be equipped with a first fixing means 16 that fixes the first detection unit 12 to the structure 2, and a second fixing means 17 that fixes the second detection unit 13 to the structure 2. As a result, the first detection unit 12 and the second detection unit 13 are separate units, and further, the first detection unit 12 and the second detection unit 13 are fixed to the structure 2 individually.

[0041] Note that the first and second fixing means 16, 17 may be configured, for example, as in the present embodiment, to be able to change the positions of the detection units 12, 13 in the second lateral direction D2 relative to the structure 2. Although not particularly limited, the first and second fixing means 16, 17 may include, for example, first brackets 16a, 17a fixed to the structure 2, second brackets 16b, 17b fixed to the detection units 12, 13, and fasteners (for example, screw members) 16c, 17c that fix the first brackets 16a, 17a and the second brackets 16b, 17b.

[0042] Furthermore, the passenger conveyor 1 may be provided with, for example, a third fixing means 18 for fixing the first detectable portion 14 to the support portion 9 by fixing the first detectable portion 14 to the elongated body 11a, as in this embodiment, and a fourth fixing means 19 for fixing the second detectable portion 15 to the support portion 9 by fixing the second detectable portion 15 to the elongated body 11a.

[0043] As a result, the first detectable portion 14 and the second detectable portion 15 are separate bodies, and moreover, the first detectable portion 14 and the second detectable portion 15 are individually fixed to the support portion 9. Therefore, the first movement position and the second movement position of the support portion 9 can be individually set.

[0044] Furthermore, the third and fourth fixing means 18, 19 may be configured, for example, as in this embodiment, to be able to change the positions of the detection targets 14, 15 in the first horizontal direction D1 relative to the support 9. Although not particularly limited, the third and fourth fixing means 18, 19 may include clamps 18a, 19a that are female-threaded members that screw into the elongated body 11a, which is a male-threaded member, and that clamp the detection targets 14, 15 in the first horizontal direction D1.

[0045] Therefore, for example, the first movement position and the second movement position of the support unit 9 can be changed by changing the positions of the detection units 12 and 13 relative to the structure 2 or by changing the positions of the detection target units 14 and 15 relative to the support unit 9. In this way, not only can the first movement position and the second movement position of the support unit 9 be set individually, but the first movement position and the second movement position of the support unit 9 can also be changed individually.

[0046] 7, the passenger conveyor 1 may include, for example, an input unit 20 to which various information (data) is input, and an output unit 21 to which various information is output. Although not particularly limited, information input to the input unit 20 may include, for example, instruction information (e.g., start / stop (start / stop) instruction information, operation mode (automatic / manual) instruction information, travel direction (up / down) instruction information, etc.), and information output by the output unit 21 may include, for example, operation information (up operation / down operation) and abnormality information.

[0047] The input unit 20 may include, for example, a switch (push button switch, select switch, etc.), a touch panel, etc. Although not particularly limited, the input unit 20 may be disposed, for example, at the end of the balustrade part 4 in the first horizontal direction D1.

[0048] The output unit 21 may include, for example, a display output unit 21a (e.g., an electronic bulletin board or a signal light) that displays information, a sound output unit 21b (e.g., a buzzer or a speaker) that emits the information as sound, and an external output unit 21c that outputs a signal to the outside (e.g., a central monitoring room in the same building or a different building). Although not particularly limited, the display output unit 21a and the sound output unit 21b may be disposed, for example, at the end of the balustrade part 4 in the first horizontal direction D1.

[0049] For example, as in this embodiment, the processing unit 6 may include an acquisition unit 6a that acquires each piece of information from each unit 12, 13, and 20, a storage unit 6b that stores each piece of information, a calculation unit 6c that calculates each piece of information, and a control unit 6d that controls each unit 5 and 21. The processing unit 6 may be a computer that includes, for example, a processor such as a CPU and an MPU (for example, the calculation unit 6c, the control unit 6d), memories such as a ROM and a RAM (for example, the acquisition unit 6a, the storage unit 6b), various interfaces, etc.

[0050] As a result, the processor executes the program stored in the memory, and the software and hardware work together to realize the units 6a to 6d of the processing unit 6. The processing unit 6 may be configured, for example, by a software circuit, or may be configured, for example, by a hardware circuit, or may be configured, for example, by a combination of a software circuit and a hardware circuit.

[0051] The processing unit 6 may be configured as a single device, or may be configured as multiple devices that can communicate with each other. Specifically, the units 6a to 6d of the processing unit 6 may be provided in a single device, or may be distributed across multiple devices that can communicate with each other.

[0052] Although not particularly limited, the second movement position may be, for example, a position where the support part 9 is located when the running part 7 is extended to an extent that requires maintenance. Furthermore, although not particularly limited, the first movement position may be, for example, a position where the support part 9 is located when the running part 7 is broken.

[0053] Then, when the second detection unit 13 detects that the support unit 9 has moved to the second movement position, the processing unit 6 causes the output unit 21 to output information that the support unit 9 has moved to the second movement position (hereinafter referred to as "second movement information"). As a result, when the second detection unit 13 detects the movement of the support unit 9, the output unit 21 outputs the second movement information. Therefore, for example, it is possible to recognize from the output unit 21 that the running unit 7 has extended to an extent that maintenance is required, without having to remove the floor plate 10 and check the support unit 9 and running unit 7 inside the machine room 2a.

[0054] When the second detection unit 13 detects that the support unit 9 has moved to the second movement position, the processing unit 6 maintains the operation of the drive source 5b. As a result, when the second detection unit 13 detects the movement of the support unit 9, the traveling unit 7 maintains traveling.

[0055] On the other hand, when first detection unit 12 detects that support unit 9 has moved to the first movement position, processing unit 6 causes output unit 21 to output information that support unit 9 has moved to the first movement position (hereinafter referred to as "first movement information"), and also stops the operation of drive source 5b. As a result, when first detection unit 12 detects the movement of support unit 9, output unit 21 outputs the first movement information, and running unit 7 stops traveling. Therefore, when running unit 7 breaks, running of running unit 7 stops, and also, it is possible to make output unit 21 recognize that running unit 7 has broken.

[0056] Then, when the first detection unit 12 has detected the movement of the support unit 9 for a first set time, the processing unit 6 stops the operation of the drive source 5b. As a result, when the first detection unit 12 has detected the movement of the support unit 9 for a first set time, the traveling unit 7 stops traveling.

[0057] Therefore, for example, if the traveling unit 7 breaks and the first detector 12 detects the movement of the support unit 9, the traveling unit 7 immediately stops traveling. Although not particularly limited, the first set time may be, for example, 0.5 seconds or less, or may be, for example, zero. Note that, for example, if the first set time is zero, when the first detector 12 detects the movement of the support unit 9, the processing unit 6 stops the operation of the drive source 5b.

[0058] On the other hand, when a second set time longer than the first set time has elapsed since the second detection unit 13 detected the movement of the support unit 9, the processing unit 6 causes the output unit 21 to output second movement information. As a result, when the state in which the second detection unit 13 detected the movement of the support unit 9 continues for the second set time, the output unit 21 outputs the second movement information.

[0059] Therefore, for example, even if second detection unit 13 erroneously detects movement of support unit 9 for just an instant due to vibration of second detectable part 15, it is possible to prevent second detection unit 13 from erroneously detecting movement of support unit 9 and outputting second movement information erroneously from output unit 21. Although not particularly limited, the second set time may be, for example, 1 to 10 seconds.

[0060] 3 and 4, the elongated body 11a includes a support and fixing part 11h fixed to the support part 9, a first detectable and fixing part 11i fixed to the first detectable part 14, and a second detectable and fixing part 11j fixed to the second detectable part 15. Since the running part 7 is hooked onto the support part 9 and the support part 9 supports the running part 7, there is a risk that as the running part 7 moves away from the support and fixing part 11h, the amplitude (amount of displacement) due to vibration of the elongated body 11a will increase.

[0061] In contrast, first detectable fixed part 11i is arranged closer to supporting and fixing part 11h in first horizontal direction D1 than second detectable fixed part 11j. That is, the distance between first detectable fixed part 11i and supporting and fixing part 11h in first horizontal direction D1 is shorter than the distance between second detectable fixed part 11j and supporting and fixing part 11h.

[0062] This makes it possible to prevent the amplitude (amount of displacement) of the first detectable fixed part 11i from increasing due to the vibration of the elongated body 11a, and therefore to prevent the amplitude (amount of displacement) of the first detectable part 14 from increasing due to the vibration of the elongated body 11a. Therefore, for example, it is possible to prevent the first detecting part 12 from erroneously detecting the movement of the support part 9 and causing the traveling part 7 to stop traveling.

[0063] Moreover, when the second detection unit 13 detects the movement of the support unit 9 while the traveling unit 7 is traveling, the processing unit 6 does not cause the output unit 21 to output the second movement information. As a result, when there is a risk that the support unit 9 and the elongated body 11a will vibrate, the output unit 21 does not output the second movement information.

[0064] On the other hand, when the second detection unit 13 detects the movement of the support unit 9 while the traveling unit 7 is stopped, the processing unit 6 causes the output unit 21 to output the second movement information. This causes the output unit 21 to output the second movement information when there is no risk of the support unit 9 and the elongated body 11a vibrating. Therefore, for example, it is possible to prevent the second detection unit 13 from erroneously detecting the movement of the support unit 9 due to vibration of the second detectable part 15, which would cause the output unit 21 to erroneously output the second movement information.

[0065] 5, in the first detection unit 12, the first movable element 12b is moved to the detection position and held at the detection position, and is operated to return from the detection position to the non-detection position. As a result, the first movable element 12b is held at the detection position by moving to the detection position, and the first detection unit 12 can reliably detect the movement of the support element 9.

[0066] The first mover 12b is operated to return from the detection position to the non-detection position, so that, for example, in order to return the first mover 12b to the non-detection position, the floor plate 10 is removed and the first detection unit 12, the support unit 9, the running unit 7, etc. can be confirmed inside the machine room 2a.

[0067] 6, the second movable element 13b automatically returns from the detection position to the non-detection position. As a result, when the support unit 9 returns from the second movement position toward the initial position, the second movable element 13b automatically returns from the detection position to the non-detection position. Therefore, for example, it is possible to prevent the second detection unit 13 from erroneously detecting the movement of the support unit 9 and the output unit 21 from erroneously outputting the second movement information.

[0068] [1] As described above, the passenger conveyor 1, as in this embodiment, a structure 2 installed on the skeleton; a circular running portion 7 that rotates and runs; a support unit 9 that supports an end of the traveling unit 7 in the first horizontal direction D1 and is movable in the first horizontal direction D1 relative to the structure 2; a tension applying unit 11b that applies a force to the running portion 7 in order to apply tension to the running portion 7; a first detection unit 12 fixed to the structure 2 and configured to detect that the support unit 9 has moved from an initial position to a first movement position spaced a first distance W1 in the first lateral direction D1; a second detection unit (13) fixed to the structure (2) and configured to detect that the support unit (9) has moved from the initial position to a second movement position in the first lateral direction (D1) by a second distance (W2) smaller than the first distance (W1); The first detection unit 12 and the second detection unit 13 are separate units and are individually fixed to the structure 2. This configuration is preferable.

[0069] According to this configuration, the first detection unit 12 detects that the support unit 9 has moved to the first movement position, and the second detection unit 13 detects that the support unit 9 has moved to the second movement position. The first detection unit 12 and the second detection unit 13 are separate units, and are fixed individually to the structure 2. This allows the first movement position and the second movement position to be set individually.

[0070] [2] In addition, the passenger conveyor 1 described above in [1] is, as in this embodiment, an output unit 21 that outputs information; the output unit 21 outputs movement information of the support unit 9 when the second detection unit 13 detects movement of the support unit 9; The traveling unit 7 continues traveling when the second detection unit 13 detects the movement of the support unit 9, and stops traveling when the first detection unit 12 detects the movement of the support unit 9. This configuration is preferable.

[0071] With this configuration, when the second detection unit 13 detects the movement of the support unit 9, the output unit 21 outputs movement information of the support unit 9, and the traveling unit 7 continues traveling. Also, when the first detection unit 12 detects the support unit 9, the traveling unit 7 stops traveling.

[0072] [3] In addition, the passenger conveyor 1 of [2] above, as in this embodiment, the output unit 21 outputs movement information of the support unit 9 when the second detection unit 13 detects movement of the support unit 9 while the traveling unit 7 is stopped, and does not output movement information of the support unit 9 when the second detection unit 13 detects movement of the support unit 9 while the traveling unit 7 is traveling; This configuration is preferable.

[0073] According to this configuration, since the traveling unit 7 is supported by the support unit 9, there is a risk that the support unit 9 will vibrate when the traveling unit 7 is traveling. However, if the second detection unit 13 detects the movement of the support unit 9 while the traveling unit 7 is traveling, the output unit 21 does not output movement information of the support unit 9. As a result, when there is a risk that the support unit 9 will vibrate, the output unit 21 does not output movement information of the support unit 9 even if the second detection unit 13 detects the movement of the support unit 9.

[0074] On the other hand, if the second detection unit 13 detects the movement of the support unit 9 when the traveling unit 7 is stopped, the output unit 21 outputs the movement information of the support unit 9. As a result, if the second detection unit 13 detects the movement of the support unit 9 when there is no risk of the support unit 9 vibrating, the output unit 21 outputs the movement information of the support unit 9.

[0075] [4] In addition, in the passenger conveyor 1 of the above [2] or [3], as in this embodiment, the traveling unit (7) stops traveling when a state in which the first detection unit (12) detects the movement of the support unit (9) has elapsed for a first set time; The output unit 21 outputs movement information of the support unit 9 when a second set time longer than the first set time has elapsed since the second detection unit 13 detected the movement of the support unit 9. This configuration is preferable.

[0076] With this configuration, traveling unit 7 stops traveling when the first detection unit 12 continues to detect the movement of support unit 9 for the first set time. As a result, when first detection unit 12 detects the movement of support unit 9, traveling unit 7 immediately stops traveling.

[0077] On the other hand, when the state in which second detection unit 13 has detected the movement of support unit 9 has elapsed for a set time, output unit 21 outputs movement information of support unit 9. As a result, when second detection unit 13 continues to detect the movement of support unit 9, output unit 21 outputs movement information of support unit 9.

[0078] [5] In addition, in any one of the passenger conveyors 1 described above in [2] to [4], as in this embodiment, a first detection target portion 14 fixed to the support portion 9 and detected by the first detection portion 12; a second detection target portion 15 fixed to the support portion 9 and detected by the second detection portion 13; The first detection unit 12 is a first detection main body 12a fixed to the structure 2; a first mover (12b) that is movable relative to the first detection main body (12a) and that detects movement of the support (9) by coming into contact with the first detection target (14) and moving from a non-detection position to a detection position; The first movable element 12b moves to the detection position and is held at the detection position, and returns from the detection position to the non-detection position by being operated, The second detection unit 13 is a second detection main body 13a fixed to the structure 2; a second mover (13b) that is movable relative to the second detection main body (13a) and that detects movement of the support (9) by coming into contact with the second detection target (15) and moving from a non-detection position to a detection position; The second movable element 13b automatically returns from the detection position to the non-detection position. This configuration is preferable.

[0079] According to this configuration, first movable element 12b is held at the detection position by moving to the detection position, and therefore first detector 12 can reliably detect the movement of support element 9. Furthermore, first movable element 12b returns from the detection position to the non-detection position by being operated.

[0080] Furthermore, the second movable element 13b automatically returns from the detection position to the non-detection position, so that when the support portion 9 returns from the second movement position to the initial position, the second movable element 13b automatically returns from the detection position to the non-detection position.

[0081] [6] In addition, in any one of the passenger conveyors 1 described above in [2] to [5], as in this embodiment, a long body 11a fixed to the support portion 9 and extending in the first horizontal direction D1; a first detection target 14 fixed to the elongated body 11a and detected by the first detection unit 12; a second detection target portion 15 fixed to the elongated body 11a and detected by the second detection portion 13; The elongated body 11a is a support fixing portion 11h fixed to the support portion 9; a first detection target fixed portion 11i fixed to the first detection target portion 14; a second detection target fixed portion 11j fixed to the second detection target portion 15, The first detectable fixed portion 11i is disposed closer to the support fixed portion 11h than the second detectable fixed portion 11j in the first horizontal direction D1. This configuration is preferable.

[0082] According to this configuration, the first detectable part 14 detected by the first detecting part 12 and the second detectable part 15 detected by the second detecting part 13 are fixed to the elongated body 11a extending in the first horizontal direction D1. Since the running part 7 is supported by the support part 9, when the running part 7 runs, there is a risk that the amplitude (amount of displacement) due to vibration of the elongated body 11a will increase as the running part 7 moves away from the support fixing part 11h.

[0083] In contrast, first detectable fixed part 11i is arranged closer to support fixed part 11h than second detectable fixed part 11j in first horizontal direction D1. This makes it possible to prevent the amplitude (amount of displacement) of first detectable fixed part 11i from increasing due to vibration of elongated body 11a, and therefore makes it possible to prevent the amplitude (amount of displacement) of first detectable part 14 from increasing due to vibration of elongated body 11a.

[0084] The passenger conveyor 1 is not limited to the configuration of the above-described embodiment, nor is it limited to the above-described effects. Furthermore, various modifications can be made to the passenger conveyor 1 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 above-described embodiment.

[0085] (A) In the passenger conveyor 1 according to the above embodiment, the output unit 21 is configured to output first movement information when the first detector 12 detects movement of the support member 9, and to output second movement information when the second detector 13 detects movement of the support member 9. However, the passenger conveyor 1 is not limited to this configuration.

[0086] For example, output unit 21 may be configured not to output the first movement information when first detection unit 12 detects movement of support unit 9. Alternatively, output unit 21 may be configured not to output the second movement information when second detection unit 13 detects movement of support unit 9.

[0087] (B) Furthermore, in the passenger conveyor 1 according to the above embodiment, the running section 7 continues to run when the second detection section 13 detects the movement of the support section 9, while the running section 7 stops running when the first detection section 12 detects the movement of the support section 9. However, the passenger conveyor 1 is not limited to this configuration.

[0088] For example, traveling unit 7 may be configured to stop traveling when second detection unit 13 detects movement of support unit 9. Alternatively, for example, traveling unit 7 may be configured to continue traveling when first detection unit 12 detects movement of support unit 9.

[0089] (C) Furthermore, in the people conveyor 1 according to the above embodiment, the output unit 21 is configured to output second movement information when the second detection unit 13 detects movement of the support unit 9 while the traveling unit 7 is stopped, whereas the output unit 21 does not output second movement information when the second detection unit 13 detects movement of the support unit 9 while the traveling unit 7 is traveling. However, the people conveyor 1 is not limited to this configuration.

[0090] For example, output unit 21 may be configured not to output the second movement information when second detection unit 13 detects movement of support unit 9 while traveling unit 7 is stopped. Alternatively, output unit 21 may be configured to output the second movement information when second detection unit 13 detects movement of support unit 9 while traveling unit 7 is traveling.

[0091] (D) Furthermore, in the passenger conveyor 1 according to the above embodiment, the traveling unit 7 stops traveling when the first detection unit 12 has detected the movement of the support unit 9 for a first set time, and the output unit 21 outputs second movement information when the second detection unit 13 has detected the movement of the support unit 9 for a second set time that is longer than the first set time. However, the passenger conveyor 1 is not limited to this configuration. The second set time may be, for example, shorter than the first set time, or may be, for example, the same as the first set time.

[0092] (E) Furthermore, in the passenger conveyor 1 according to the above embodiment, the first detector 12 is configured to detect the movement of the support member 9 by the first mover 12b coming into contact with the first detectable member 14, thereby moving from a non-detection position to a detection position. However, the passenger conveyor 1 is not limited to this configuration. For example, the first detector 12 may be a photoelectric sensor that detects the first detectable member 14 without coming into contact with it.

[0093] (F) Furthermore, in the passenger conveyor 1 according to the above embodiment, the second detecting unit 13 is configured to detect the movement of the support member 9 by the second mover 13b coming into contact with the second detected member 15, thereby moving from a non-detection position to a detection position. However, the passenger conveyor 1 is not limited to this configuration. For example, the second detecting unit 13 may be configured as a photoelectric sensor that detects the second detected member 15 without coming into contact with the second detected member 15.

[0094] (G) Furthermore, in the passenger conveyor 1 according to the above embodiment, the first mover 12b of the first detector 12 is configured to move to the detection position, be held at the detection position, and return from the detection position to the non-detection position when operated. However, the passenger conveyor 1 is not limited to this configuration. For example, the first mover 12b of the first detector 12 may be configured to automatically return from the detection position to the non-detection position.

[0095] (H) Furthermore, in the passenger conveyor 1 according to the above embodiment, the second mover 13b of the second detection unit 13 is configured to automatically return from the detection position to the non-detection position. However, the passenger conveyor 1 is not limited to this configuration. For example, the second mover 13b of the second detection unit 13 may be configured to move to the detection position, be held at the detection position, and then return from the detection position to the non-detection position when operated.

[0096] (I) Furthermore, in the passenger conveyor 1 according to the above embodiment, the first detectable part 14 is fixed to the support part 9 by being fixed to the elongated body 11a, and the second detectable part 15 is fixed to the support part 9 by being fixed to the elongated body 11a. However, the passenger conveyor 1 is not limited to this configuration. For example, the first detectable part 14 may be fixed directly to the support part 9. Also, for example, the second detectable part 15 may be fixed directly to the support part 9.

[0097] (J) Furthermore, in the passenger conveyor 1 according to the above embodiment, the first detectable fixed portion 11i is arranged closer to the support fixed portion 11h in the first horizontal direction D1 than the second detectable fixed portion 11j. However, the passenger conveyor 1 is not limited to this arrangement. For example, the second detectable fixed portion 11j may be arranged closer to the support fixed portion 11h in the first horizontal direction D1 than the first detectable fixed portion 11i.

[0098] (K) Furthermore, in the passenger conveyor 1 according to the above embodiment, the detecting units 12, 13 are configured so that their positions in the second horizontal direction D2 relative to the structure 2 can be changed by the fixing means 16, 17, and the detected units 14, 15 are configured so that their positions in the first horizontal direction D1 relative to the support unit 9 can be changed by the fixing means 18, 19. However, the passenger conveyor 1 is not limited to this configuration.

[0099] The detectors 12 and 13 may be configured, for example, to be able to change their positions in the first horizontal direction D1 relative to the structure 2. The detectors 12 and 13 may also be configured, for example, to be able to change their positions in each of the first horizontal direction D1 and the second horizontal direction D2 relative to the structure 2.

[0100] The detected parts 14, 15 may be configured, for example, such that the positions thereof in the second horizontal direction D2 are changeable relative to the support part 9. The detected parts 14, 15 may be configured, for example, such that the positions thereof in each of the first horizontal direction D1 and the second horizontal direction D2 are changeable relative to the support part 9.

[0101] Furthermore, for example, the detecting units 12 and 13 may be configured so that their positions relative to the structure 2 cannot be changed, and the detected units 14 and 15 may be configured so that their positions relative to the support unit 9 cannot be changed. Although not particularly limited, for example, the detecting units 12 and 13 may be fixed to the structure 2 by welding, and the detected units 14 and 15 may be fixed to the support unit 9 or the elongated body 11a by welding. Even in such a configuration, the first movement position and the second movement position can be set individually by adjusting the positions of the respective welds.

[0102] (L) Furthermore, in the passenger conveyor 1, for example, as shown in Figure 8, the long body 11a may be configured to have a first male screw material 11k fixed to the support portion 9 (see Figure 3) and the first detectable portion 14, a second male screw material 11m fixed to the second detectable portion 15, and a female screw material 11n connecting the first male screw material 11k and the second male screw material 11m.

[0103] With this configuration, for example, the second detecting section 13 and the second detectable section 15 can be newly installed on an existing passenger conveyor 1 that only has the first detecting section 12 and the first detectable section 14. In Figure 8, the second detecting section 13 and the second fixing means 17 are shown by two-dot chain lines.

[0104] (M) It should be noted that, for example, the order of execution of each process, such as operations, procedures, steps, and stages, in the systems, methods, programs, and devices shown in the claims, specifications, and drawings, can be realized in any order, as long as the output of a previous process is not used in a subsequent process. For example, even if the terms "first" and "next" are used for convenience, this does not mean that the processes must be executed in that order. [Explanation of symbols]
