[0005] Patent Document 1: Japanese Patent Application Publication No. 2011-219247 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In conventional measurement and adjustment tools like those described above, the position of the recording section relative to the scale section is checked while the position of the skirt board relative to the step is adjusted so that the size of the gap between the skirt board and the step is within the allowable range at multiple measurement points. Therefore, it is not easy to determine whether the size of the gap is appropriate along the entire length of the skirt board.

[0008] This disclosure was made to solve the aforementioned problems, and its purpose is to provide an inspection device and method for passenger conveyors that can easily determine whether the size of the gap between the steps and the skirt is appropriate.

[0009] Methods for solving problems

[0010] The passenger conveyor inspection device disclosed herein includes: a support platform having a base portion disposed on a step and a roller mounting portion disposed on the base portion; and a detection roller rotatably disposed on the roller mounting portion. When the base portion is disposed on the step, the detection roller protrudes from the side of the step and rotates when in contact with the skirt panel. The device detects whether the size of the gap between the step and the skirt panel is abnormal by determining whether the detection roller rotates when the step is moved while the base portion is disposed on the step.

[0011] The passenger conveyor inspection method disclosed herein includes: a setting step in which an inspection device having a support platform and an inspection roller rotatably mounted on the support platform is set onto a step, and the protrusion amount of the inspection roller protruding from the side of the step is set; and a judgment step in which, while moving the step, the inspection roller is checked to see if it rotates due to contact with the skirt board, thereby determining whether the size of the gap between the step and the skirt board is appropriate.

Detailed Implementation

[0026] The embodiments will now be described with reference to the accompanying drawings.

[0027] Implementation method 1.

[0028] Figure 1 This is a schematic side view of the escalator according to Embodiment 1. In the figure, a truss 11 is erected between the upper and lower floors of the building. Multiple steps 12 are supported by the truss 11. The multiple steps 12 are connected in a ring. Figure 1 The image shows only a portion of the multiple rungs 12.

[0029] A pair of left and right railings 13 are erected on the truss 11. Each railing 13 has a railing body 14 and a skirt 15. The skirt 15 is disposed between the lower end of the railing body 14 and a plurality of steps 12.

[0030] Each railing 13 has a movable handrail 16 installed on its main body 14. The movable handrail 16 moves synchronously with the movement of the multiple steps 12.

[0031] A drive motor 17, a pair of upper sprockets 18 on the left and right, and a control panel 19 are provided in the first end of the truss 11. The first end is the upper end of the truss 11 in the length direction.

[0032] The drive motor 17 rotates the upper sprocket 18. The control panel 19 controls the operation of the escalator by controlling the drive motor 17.

[0033] A pair of lower sprockets 20 are provided at the second end of the truss 11. The second end of the truss 11 is the lower end on the lower side in the length direction of the truss 11.

[0034] A pair of annular step chains 21 are wound around a pair of upper sprockets 18 and a pair of lower sprockets 20. Multiple steps 12 are connected to the pair of step chains 21 respectively. As the upper sprockets 18 rotate, the step chains 21 circulate, and the multiple steps 12 circulate along the movement path.

[0035] The movement paths of multiple steps 12 include outbound routes and return routes. The outbound route is the section where the user can ride the step 12. The return route is the section where the step 12 returns from the end of the outbound route to the beginning of the outbound route.

[0036] Figure 2 It is an enlarged representation Figure 1 The side view of section II shows the status during the inspection operation. Additionally, in Figure 2 The railing 13 is omitted in the text.

[0037] Although Figure 1 The details are omitted, but the truss 11 is equipped with a drive rail 22 and a follower rail 23. The drive rail 22 guides the movement of multiple steps 12. The follower rail 23 controls the attitude of each step 12.

[0038] Each step 12 has a frame 24, a tread 25, a vertical plate 26, a step shaft 27, a pair of left and right drive rollers 28, and a pair of left and right follower rollers 29.

[0039] The tread 25 is fixed to the upper part of the frame 24. That is, when the step 12 is in the outgoing section of the movement path, the tread 25 is located on the upper part of the frame 24. The vertical plate 26 is fixed to the lower end of the frame 24.

[0040] The step shaft 27 is positioned at the upper end of the frame 24 along the width direction of the step 12. The width direction of the step 12 is perpendicular to both the direction of movement of the step 12 and the vertical direction. Figure 2 The direction perpendicular to the paper. The direction of movement of step 12 is, for example,... Figure 2 The upward direction is indicated by arrow A.

[0041] The step shaft 27 is connected to a pair of step chains 21. Thus, multiple steps 12 are connected to form a loop.

[0042] A pair of drive rollers 28 are rotatably mounted on the step shaft 27 on both sides of the step 12 in the width direction. In addition, the pair of drive rollers 28 roll on a pair of drive tracks 22 as the step 12 moves.

[0043] A pair of following rollers 29 are rotatably disposed on both sides of the lower end of the frame 24 in the width direction of the step 12. In addition, the pair of following rollers 29 roll on a pair of following tracks 23 as the step 12 moves.

[0044] Two inspection devices 50 are installed on one of the multiple steps 12 located in the outgoing section. Hereinafter, the step 12 with the inspection devices 50 will be referred to as the "object step".

[0045] Two inspection devices 50 are installed on the target tread when checking whether the gap between the step 12 and the skirt 15 is appropriate. In this example, the two inspection devices 50 are arranged at the upper and lower ends of the tread 25 of the target step.

[0046] The gap between step 12 and skirt 15 has an allowable range. For example, the minimum allowable range is 1mm and the maximum is 4mm. In this case, a gap smaller than 1mm or a gap larger than 4mm is considered abnormal.

[0047] Each inspection device 50 includes a support platform 51 and an inspection roller 54. The support platform 51 has a base portion 52 and a roller mounting portion 53. The base portion 52 is disposed on the tread 25 of the target step. The roller mounting portion 53 is disposed on the base portion 52.

[0048] The detection roller 54 is rotatably mounted on the roller mounting portion 53. The rotation center of the detection roller 54 is parallel to a direction in the inclined portion of the path section that is perpendicular to the moving direction of the step 12 and perpendicular to the width direction of the step 12.

[0049] Figure 3 It is observed along arrow III. Figure 2 The front view of the ladder 12 and the inspection device 50. Figure 4 It is an enlarged representation Figure 3 The front view of section IV.

[0050] Multiple anti-slip strips 25a are provided on the upper surface of the tread 25. Each anti-slip strip 25a is provided in a groove of the tread 25 along the front-back direction of the step 12. The front-back direction of the step 12 is a direction that is perpendicular to the width direction of the step 12 and perpendicular to the vertical direction in the passageway.

[0051] A plurality of protrusions 52a are provided on the lower surface of the base portion 52. The base portion 52 is mounted on the tread 25 of the target step by embedding each protrusion 52a into the corresponding tread anti-slip strip 25a. When the base portion 52 is mounted on the tread 25, the side of the base portion 52 is coplanar with the side of the step 12.

[0052] Each skirt panel 15 is positioned opposite the side of the step 12 with a gap between them. When the base portion 52 is mounted on the tread 25, the detection roller 54 protrudes from the side of the step 12 toward the side of the skirt panel 15.

[0053] The detection roller 54 rotates when it comes into contact with the skirt plate 15. In addition, the outer periphery of the detection roller 54 is made of a soft material that deforms when pressed by the skirt plate 15.

[0054] The inspection device 50 detects whether the size of the gap between the step 12 and the skirt plate 15 is abnormal by checking whether the detection roller 54 rotates when the multiple steps 12 are moved while the base part 52 is set on the target step.

[0055] Figure 5 It means Figure 4 A top view of the base portion 52. A fitting hole 52b is provided on the upper surface of the base portion 52. The planar shape of the fitting hole 52b is oblong. The length direction of the fitting hole 52b is parallel to the width direction of the step 12.

[0056] Figure 6 It means Figure 4 A perspective view of the roller mounting portion 53. A cylindrical rotating shaft portion 53a is provided at the upper end of the roller mounting portion 53. The detection roller 54 is rotatably mounted on the rotating shaft portion 53a.

[0057] A fitting protrusion 53b is provided at the lower end of the roller mounting portion 53. The fitting protrusion 53b is embedded in the fitting hole 52b. That is, the base portion 52 and the roller mounting portion 53 in Embodiment 1 are composed of different components.

[0058] The roller mounting portion 53 can be mounted and detached from the base portion 52. Furthermore, the orientation in which the roller mounting portion 53 is mounted relative to the base portion 52 can be changed between a first orientation and a second orientation. The first orientation is... Figure 6 The orientation shown. The second orientation is the same as... Figure 6 The opposite direction.

[0059] The rotating shaft portion 53a is located closer to one side of the center of the fitting protrusion 53b. Therefore, the position of the detection roller 54 in the width direction of the step 12 is different when the roller mounting portion 53 is mounted on the base portion 52 in the first orientation and when the roller mounting portion 53 is mounted on the base portion 52 in the second orientation.

[0060] Therefore, the position of the detection roller 54 relative to the base portion 52 can be changed between a first position and a second position along the width direction of the step 12. By mounting the roller mounting portion 53 to the base portion 52 in a first orientation, the detection roller is located in the first position relative to the base portion 52. Furthermore, by mounting the roller mounting portion 53 to the base portion 52 in a second orientation, the detection roller 54 is located in the second position relative to the base portion 52.

[0061] The first position is the position where the detection roller 54 does not contact the skirt plate 15 if the gap between the step 12 and the skirt plate 15 is greater than or equal to the minimum allowable value. Alternatively, the first position is the position where the detection roller 54 contacts the skirt plate 15 when the gap is less than the minimum value.

[0062] The second position is the position where the detection roller 54 contacts the skirt plate 15 if the gap size is below the maximum allowable value. Additionally, the second position is the position where the detection roller 54 does not contact the skirt plate 15 when the gap size exceeds the maximum value.

[0063] When the detection roller 54 is in the second position, the amount by which the detection roller 54 protrudes from the side of the object step is greater than the amount by which the detection roller 54 protrudes from the side of the object step when it is in the first position.

[0064] Therefore, when the step 12 is moved while the detection roller 54 is in the first position, by confirming that the detection roller 54 is rotating, an anomaly that the gap size is less than the minimum value can be detected.

[0065] Furthermore, when the step 12 is moved while the detection roller 54 is in the second position, an anomaly where the gap size exceeds the maximum value can be detected by confirming that the rotation of the detection roller 54 has stopped.

[0066] Preferably, the inspection roller 54 has a pattern for the operator to visually confirm whether the inspection roller 54 is rotating.

[0067] Figure 7 It means Figure 4 A top view of the first example of the pattern on the detection roller 54. Figure 8 It means Figure 4 A top view of a second example of the pattern on the detection roller 54.

[0068] exist Figure 7 In the middle, the upper surface of the detection roller 54 has multiple straight line patterns 54a radially arranged. Figure 8 In the middle, the upper surface of the detection roller 54 has a plurality of dot patterns 54b at equal intervals. Such patterns can also be made on the side of the detection roller 54.

[0069] Next, an example of the steps for an inspection operation using the inspection device 50 will be described. With multiple steps 12 stopped, the operator selects one step 12 located in the lower bend of the path section as the target step and removes the step 12 above the target step.

[0070] Next, the operator sets up two inspection devices 50 on the object step. At this time, the position of the detection rollers 54 in the two inspection devices 50 is set to the first position. That is, the protrusion amount of each detection roller 54 from the side of the object step is set to the minimum value.

[0071] The operator rides on a step 12 that allows them to visually see the positions of each detection roller 54, such as the target step or the step below the target step, and moves the escalator upward. If the detection roller 54 rotates during the upward movement, the operator marks the position of the rotation of the detection roller 54 in the skirt panel 15.

[0072] After the object step has moved to the upper end of the destination section, the operator stops the escalator. Furthermore, if there are marked areas on the skirt panel 15, the operator adjusts the position of the skirt panel 15 to ensure that the gap size at the marked areas is within acceptable limits.

[0073] Afterwards, the operator sits in a position where they can visually see each detection roller 54, and lowers the escalator to mark the position where the detection roller 54 in the skirt panel 15 has rotated.

[0074] After the object step has moved to the lower end of the destination section, the operator stops the escalator. Furthermore, if there are marked areas on the skirt panel 15, the operator adjusts the position of the skirt panel 15 to ensure that the gap size at the marked areas is within acceptable limits.

[0075] Next, the operator changes the position of each detection roller 54 to the second position and performs the same operation as described above. However, in this case, a mark is made at the position where the rotation of the detection roller 54 stops.

[0076] Afterwards, the operator checks the gap between the opposite side skirt 15 and the side of the step 12 using the same steps as described above, and adjusts the position of the skirt 15 as needed.

[0077] Thus, the inspection method for the escalator in Implementation Method 1 includes a setup process and a judgment process.

[0078] The setting process involves placing two inspection devices 50 onto the step 12 and setting the protrusion amount of the inspection roller 54 from the side of the step 12.

[0079] The judgment process is as follows: while moving the step 12, it is confirmed whether the detection roller 54 rotates due to contact with the skirt plate 15, thereby determining whether the size of the gap between the step 12 and the skirt plate 15 is appropriate.

[0080] Furthermore, the setup process includes a first setup process and a second setup process. Moreover, the judgment process includes a first judgment process and a second judgment process. The first judgment process is performed between the first setup process and the second setup process. The second judgment process is performed after the second setup process.

[0081] In the first setting process, the protrusion amount of the detection roller 54 protruding from the side of the step 12 is set to either a first protrusion amount or a second protrusion amount. In the second setting process, the protrusion amount of the detection roller 54 protruding from the side of the step 12 is set to the other of the first protrusion amount and the second protrusion amount.

[0082] The first protrusion amount is the protrusion amount of the detection roller 54 when it is in the first position. That is, the first protrusion amount is as follows: if the size of the gap is above the minimum value of the allowable range, the detection roller 54 does not contact the skirt plate 15; if the size of the gap is less than the minimum value, the detection roller 54 contacts the skirt plate 15 and rotates.

[0083] The second protrusion amount is the protrusion amount of the detection roller 54 when it is in the second position. That is, the second protrusion amount is as follows: if the size of the gap is below the maximum value of the allowable range, the detection roller 54 contacts the skirt plate 15 and rotates; if the size of the gap exceeds the maximum value, the detection roller does not contact the skirt plate 15.

[0084] In this escalator inspection device 50 and inspection method, the size of the gap between the step 12 and the skirt panel 15 is detected by whether the detection roller 54 rotates. Therefore, it is easy to determine whether the size of the gap between the step 12 and the skirt panel 15 is appropriate.

[0085] This can improve the efficiency of installation and maintenance work and reduce the time spent on the work.

[0086] Furthermore, in the inspection device 50, the position of the detection roller 54 relative to the base portion 52 can be changed between a first position and a second position. Additionally, in the inspection method, the amount of protrusion of the detection roller 54 from the side of the step 12 is switched between a first protrusion amount and a second protrusion amount. Therefore, it is easy to determine whether the size of the gap is within the allowable range.

[0087] Furthermore, the orientation of the mounting roller 53 relative to the base portion 52 can be changed between a first orientation and a second orientation. Moreover, by switching between the first and second orientations, the position of the detection roller 54 can be switched between a first position and a second position. Therefore, the efficiency of the inspection operation can be further improved.

[0088] Furthermore, a fitting hole 52b is provided in the base portion 52, and a fitting protrusion 53b is provided in the roller mounting portion 53. Therefore, the position of the inspection roller 54 can be switched between the first position and the second position with a simple structure. As a result, the efficiency of the inspection operation can be further improved.

[0089] Furthermore, the outer periphery of the detection roller 54 is made of a soft material that deforms when pressed by the skirt plate 15. Therefore, it is possible to detect anomalies where the gap between the step 12 and the skirt plate 15 is smaller than the minimum value using a simple structure.

[0090] In addition, the inspection roller 54 is patterned. Therefore, the operator can visually confirm whether the inspection roller 54 is rotating through its simple structure. This further improves the efficiency of the inspection operation.

[0091] Alternatively, one or more holes, one or more recesses, or one or more protrusions can be provided on the detection roller 54 to replace the pattern.

[0092] Alternatively, in the inspection method, the inspection at the first protrusion level can be performed after the inspection at the second protrusion level.

[0093] Implementation method 2.

[0094] then, Figure 9 This is a side view of the inspection device 60 according to Embodiment 2. Figure 10 This is a block diagram showing the main parts of the inspection device 60 in Embodiment 2.

[0095] The inspection device 60 of Embodiment 2 has two inspection device bodies 61, a control device 58, and an LED display device 59.

[0096] In addition to the structure of the inspection device 50 in Embodiment 1, each inspection device body 61 also includes a base 55, a detection plate 56, and a sensor 57.

[0097] The platform 55 is fixed to the upper surface of the detection roller 54 and rotates together with the detection roller 54. The detection plate 56 is fixed on the platform 55 and rotates together with the platform 55. In addition, the detection plate 56 is made of iron circular plate. On the detection plate 56, a plurality of slits or holes are provided at equal intervals along the circumference of the detection plate 57.

[0098] Sensor 57 is supported on base 52. Sensor 57 is positioned opposite the upper surface of detection piece 56. Sensor 57 detects the rotation of detection piece 56, i.e., the rotation of detection roller 54. For example, a proximity sensor may be used as sensor 57.

[0099] Signals from sensors 57 of each inspection device body 61 are input to control device 58. Control device 58 controls LED display device 59 based on signals from sensors 57 of each inspection device body 61. Control device 58 is placed near inspection device body 61, for example on the object step or on an adjacent step 12 of the object step.

[0100] The LED display device 59 indicates whether each detection roller 54 is rotating. The LED display device 59 is equipped with two indicator lights corresponding to the detection rollers 54 of the two inspection device bodies 61. Each indicator light illuminates when the corresponding detection roller 54 is detected to be rotating.

[0101] The LED display device 59 can also receive command signals from the control device 58 via wireless communication. In this case, by making the LED display device 59 portable, the operator can confirm whether the size of the gap is appropriate from a position away from the main body 61 of the inspection device.

[0102] The other structures and inspection methods of Embodiment 2 are the same as those of Embodiment 1.

[0103] With such an inspection device 60 and inspection method, the same effect as in embodiment 1 can be obtained.

[0104] In addition, it can more clearly confirm whether the inspection roller 54 is rotating, which can further improve the efficiency of the inspection operation.

[0105] Furthermore, the number of inspection devices 50 in Embodiment 1 and the number of inspection device bodies 61 in Embodiment 2 are not particularly limited. For example, in Embodiment 1, only one inspection device 50 may be provided at the center of the front-back direction of the step 12. Similarly, in Embodiment 2, only one inspection device body 61 may be provided at the center of the front-back direction of the step 12.

[0106] Furthermore, in embodiments 1 and 2, the planar shape and number of the fitting hole 52b and the fitting protrusion 53b are not limited to the examples described above. For example, the planar shape of the fitting hole 52b may also be rectangular, elliptical, etc.

[0107] Alternatively, in embodiments 1 and 2, a fitting hole may be provided in the roller mounting portion 53, and a fitting protrusion may be provided in the base portion 52.

[0108] Furthermore, in embodiments 1 and 2, the position of the detection roller 54 relative to the base portion 52, that is, the amount of protrusion of the detection roller 54 from the side of the step 12, may not be phased, but can be continuously adjusted.

[0109] In addition, in embodiments 1 and 2, the base portion 52 and the roller mounting portion 53 may not be different components, but may be configured as a single component.

[0110] Furthermore, in Embodiment 2, the display device is not limited to the LED display device 59.

[0111] In addition, in embodiments 1 and 2, the passenger conveyor is not limited to escalators, but can also be a moving walkway.

[0112] The preferred embodiments have been described in detail above, but are not limited to the embodiments described above. Various modifications and substitutions can be made to the embodiments described above without departing from the scope of the claims.

[0146] (Note 8)

[0147] A method for inspecting a passenger conveyor, comprising:

[0148] In the setting process, an inspection device having a support platform and a detection roller rotatably mounted on the support platform is mounted on a step, and the protrusion amount of the detection roller protruding from the side of the step is set; and

[0149] In the judgment process, while moving the steps, it is confirmed whether the detection roller rotates due to contact with the skirt board, thereby determining whether the size of the gap between the steps and the skirt board is appropriate.

[0150] (Note 9)

[0151] According to the inspection method for passenger conveyors described in Appendix 8, wherein,

[0152] The setting process includes a first setting process and a second setting process.

[0153] The determination process includes a first determination process performed between the first setting process and the second setting process, and a second determination process performed after the second setting process.

[0154] In the first setting step, the protrusion amount is set to either a first protrusion amount or a second protrusion amount.

[0155] In the second setting step, the protrusion amount is set to the other one of the first protrusion amount and the second protrusion amount.

[0156] The first protrusion amount is as follows: if the size of the gap is greater than or equal to the minimum allowable range, the detection roller does not contact the skirt panel; if the size of the gap is less than the minimum allowable range, the detection roller contacts the skirt panel and rotates.

[0157] The second protrusion amount is as follows: if the size of the gap is below the maximum value of the allowable range, the detection roller contacts and rotates with the skirt board; if the size of the gap exceeds the maximum value, the detection roller does not contact the skirt board.
