Description

TECHNICAL FIELD

[0001] The present application relates to an inspection device for a passenger conveyor. BACKGROUND

[0002] In the operation confirmation inspection of an assembled passenger conveyor, there is an inspection of confirming the presence or absence of abnormal sound (abnormal vibration) by circulating the step (stair). As one example of the abnormal sound that occurs frequently, there is an abnormal sound caused by the contact of the circulating step and the apron provided on both sides thereof.

[0003] The worker who assembles the passenger conveyor in the factory tries to adjust the installation of the apron by relying on the sound to infer the occurrence site, but since the inspection environment in the factory is not necessarily a silent state, it is sometimes difficult to distinguish the surrounding noise and the abnormal sound.

[0004] On the contrary, in order to not rely on the sound, an automatic gap measuring device of a passenger conveyor provided with a distance sensor and a controller is known (for example, Patent Literature 1) which performs an inspection in a short time as to whether or not the gap between each of the two side surfaces of the step and the apron is within the allowable range. In this automatic gap measuring device, the controller acquires the measurement data obtained by the distance sensor in time series during the step travel, and when the gap threshold value is exceeded, it is determined that a gap abnormality has occurred.

[0007] Patent Literature 1: Japanese Patent Laid-Open No. 2018-122944 SUMMARY

[0008] PROBLEMS TO BE SOLVED BY THE INVENTION

[0009] The inspection device for a passenger conveyor described in Patent Literature 1 does not take into account the bending of the step that occurs in the circulation due to the gap of the step wheel (gap in the axle direction), the gap of the step and the step chain, the installation error of the guide rail on which the step wheel travels, and the like.

[0010] Such a bent step does not always travel on the designed step travel center line. Therefore, in the inspection device for a passenger conveyor of Patent Literature 1, although it is possible to detect whether or not the apron is installed with a predetermined amplitude, it is difficult to determine whether or not it is installed at a predetermined position with respect to the reference core (absolute coordinates) of the passenger conveyor frame (hereinafter, simply referred to as "frame").

[0011] In this state, that is, in the case where the position of the apron is adjusted only by the gap information (relative coordinates) of the step and the apron without considering the amount of bending of the step, the positions of the aprons on both sides are not adjusted with respect to the reference core (absolute coordinates) of the frame. Therefore, depending on the bending state of the step, an abnormal sound can sometimes occur again after adjustment, and there is a problem that adjustment is required again.

[0012] The present application was completed in view of the above problems, and an object thereof is to provide an inspection device for a passenger conveyor that effectively checks whether the positions of aprons noncontactly provided on both sides of a step are appropriate.

[0013] Technical means for solving the technical problem

[0014] The present application that solves the above problems is an inspection device for a passenger conveyor that can measure the assembled mutual positions, including: a reference core provided in a frame and parallel to the advancing direction of the passenger conveyor; a step that can simulate an actual working state and perform inspection as an inspection jig; a reference core sensor provided to the step; a distance sensor provided to the step and detecting an apron distance from the side surface of the step to the apron; and a control section that calculates the position of the apron with respect to the reference core using the output signals of the reference core sensor and the distance sensor.

[0015] Effects of the invention

[0016] According to the present application, an inspection device for a passenger conveyor that effectively checks whether the positions of aprons noncontactly provided on both sides of a step are appropriate is provided. The above problems, structures, and effects become more apparent through the following embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0033] Embodiments of the present application will be described below using the drawings. In addition, the same reference numerals are assigned to the same structures in each drawing, and the description is sometimes omitted in the case of overlapping descriptions. The drawings used are Figures 8 to 15 An escalator 1, which is a main application object of the present application, is exemplified, and will be referred to as a passenger conveyor 1 in the following with an upper concept.

[0034] The present device 100 is an inspection jig for accurately performing position adjustment of the apron 4 in a short time at a stage where the passenger conveyor 1 is assembled in a factory before installation. The present device 100 is used in a state where the passenger conveyor 1 is assembled in the factory. Figure 16 A basic example of the present device 100 will be described. A modified example of the present device will be described using Figure 1

[0035] In addition, the control section 104 shown in each drawing and a bending amount determination section not shown are formed by executing a program stored in a memory by a microcomputer or the like. In addition, the various constituent elements of the present application do not need to necessarily exist independently, but one constituent element can be constituted by a plurality of components, a plurality of constituent elements can be constituted by one component, a certain constituent element can be a part of another constituent element, a part of a certain constituent element can be duplicated with a part of another constituent element, and the like.

[0036] (Basic configuration of passenger conveyor)

[0037] Figures 8 to 10 is a schematic side view of a general passenger conveyor 1, which is an application object of the present device 100 (see Figure 1 ). The passenger conveyor 1 is conveyed to a construction site and installed in a state where one piece (a railing 3 or a particularly long and large division) is assembled as shown in Figure 2 The passenger conveyor 1 further generally includes a landing 11, a frame 12, an endless step chain 13, a plurality of steps 5, an apron 4, the railing 3, a handrail 2, and a drive device 8.

[0038] The landing 11 is provided so as to coincide with the height of each of an upper floor and a lower floor, so that passengers get on and off. The frame 12 is supported so as to span the upper and lower landings 11. The plurality of steps 5 are connected to the endless step chain 13 and move in a loop. The apron 4 is erected on both sides of the moving direction of the steps 5. The railing 3 is provided at the upper portion of the apron 4.

[0039] ​The handrail 2 is guided to circulate around the periphery of the balustrade 3. In the frame 12, one end thereof in the longitudinal direction is supported by a shaft on the driving side end gear 6, and the other end is supported by a shaft on the driven side end gear 7. The step chain 13 is wound in a circulatable manner across the driving side end gear 6 and the driven side end gear 7.

[0040] The driving side end gear 6 is driven by a driving device 8 in the vicinity thereof via a short driving chain 9. The handrail 2 is also driven in synchronization with the steps 5 by the power of the driving device 8.

[0041] (Basic configuration of the steps)

[0042] Next, using Figure 2 , only one of the connected steps 5 is close-uped, and the other steps are deleted from the drawing to be described. Figure 2 is a side sectional view for explaining the posture of the steps 5 in the middle portion of the frame 12. The steps 5 are mainly composed of a tread 16 on which a passenger rides, a cushion 17, a front wheel 18, a rear wheel 19, a bracket 20, and a step guide 21.

[0043] In addition, here, the designations of the front wheel 18 and the rear wheel 19 are premised on the passenger conveyor 1 being operated in the ascending direction. If the direction of movement is reversed, the front-rear relationship is reversed, and the designations are changed. However, since this does not coincide with the essence of the present invention, this is not taken into consideration, and only the case in which the passenger conveyor 1 has the front wheel 18 built in the step chain 13 is exemplified.

[0044] As shown in Figures 3 to 7 , the passenger conveyor 1 is a structure in which a front wheel guide rail 22 and a rear wheel guide rail 23 are provided in the frame 12, and the steps 5 move thereon. In order to suppress the bending of the steps 5, the step guide 21 is provided to project from the side surface of the bracket 20 toward the apron 4, and in order to prevent the approach of the two, a spacer is installed to be interposed between the opposing surfaces (see Figures 9 to 11 , Figure 14 , and Figures 3 to 7 ).

[0045] (Malfunction of the installation of the apron)

[0046] Using Figure 3 , a state of extreme malfunction of the installation of the apron 4 is shown to be described. Figure 3 is a plan view showing a step difference generated in the continuation portion of the apron 4 as a sample of a gap abnormality that should be detected by the present device 100.

[0047] In Figure 3 , at least in the case of plan view, the apron 4c is connected to the apron 4d by a good continuation that maintains linearity. In this case, the gap between the side surface of the bracket 20 and the apron 4 is substantially maintained in the ideal state. In contrast to this,Figure 4 The skirting plate 4a cannot maintain straightness with the skirting plate 4b. Therefore, the gap between the side of the bracket 20 and the skirting plate 4a is not ideal.

[0048] Figure 3 Is as with Figure 4 Samples of different types of gap anomalies, shown in a top view representing the bending of the skirt panel's fin. Figure 5 At least from a top view, the joints of skirt panels 4a and 4b are curved, thus they cannot maintain straightness.

[0049] Therefore, the sides of the bracket 20 and the skirt panel 4a are not parallel, and their gap is not ideal.

[0050] Figure 3 Is as with Figure 4 and Figure 5 Samples of gap anomalies of different types are illustrated in a top view of a skirting panel 4e that is warped relative to the direction of step advance. Figure 6 In the meantime, at least from a top view, the warped skirt-shaped guard plate 4e is not parallel to the side of the support 20, and the gap between them is not ideal.

[0051] Figures 3 to 5 Is as with Figure 6 Samples of gap anomalies of different types are illustrated in the top view of the skirting plate 4a, which is neither a continuation nor parallel to the direction of the step's advance. Figure 7 In the case of a top view, when the opposite skirt panels 4a and 4c are not parallel, the skirt panel 4a, which is not parallel to the direction of the step's movement, is not parallel to the side of the bracket 20, and their gap is not ideal.

[0052] (The steps are bent)

[0053] Figures 3 to 6 Is as with Figure 7 Examples of different types of gap anomalies are illustrated by a top view of the skirt panels 4 arranged parallel to the center line 14 of the step and the step 5b that slides and bends in a right-angle direction forward between them.

[0054] exist Figure 8 The diagram shows the bending state of step 5. Due to the clearance of the wheels of step 5 (clearance in the axle direction), the clearance between step 5 and step chain 13, and installation errors of the guide rails for the wheels of step 5, step 5 bends slightly during the cycle. Therefore, step 5 does not always travel stably on the designed step travel centerline 14.

[0055] [Basic example]

[0056] Figure 1This is a schematic side view illustrating the installation of the device 100 as an inspection fixture and the partial perspective inspection of the passenger conveyor 1. Additionally, for Figure 8 The parts described in the text are the same, and repeated descriptions are omitted.

[0057] In the configuration Figure 8 Of the multiple steps 5 of the passenger conveyor 1, only the step shown in the middle position of the frame 12 is replaced with this device 100. The reason for showing this device 100 in the middle position is simply because... Figure 9 It is easily visible and located at a position connected according to the cyclic operation of the other steps 5. Furthermore, the passenger conveyor 1 includes a reference core 101 parallel to the direction of travel of the step 5. This reference core 101 is disposed within the frame 12.

[0058] In this device 100, the reference core 101 is a single linear material such as piano wire or fishing line, and it is stretched securely within the frame 12, positioned so as not to cause interference during the circulation of the device 100. Furthermore, for ease of explanation, although the illustration shows the reference core 101 aligned with the designed step travel centerline on the same plane, the reference core 101 can also be positioned at any location within the frame 12.

[0059] Next, we will refer to Figure 10 and Figure 9 This device 100 is described in detail. Figure 8 Is Figure 10 This is a schematic side view of the device 100 shown only in a partially magnified perspective view under the current state. Figure 9 Partial perspective from the direction of travel on the steps Figure 9 A schematic front view of the device 100 is shown. Additionally, in Figure 2 In China, for Figure 9 The structure of step 5, including the front wheel 18, step chain 13, and front wheel guide rail 22, is not shown in the figure for simplicity, but is actually installed.

[0060] In addition to the structure of the ladder 5 described above, the device 100 also includes a reference core sensor 102, a distance sensor 103, a control unit 104, and a power supply unit 105. The reference core sensor 102 is connected to the main body of the device 100 via a reference core sensor support 106.

[0061] In the device 100, which is a basic example, the reference core sensor 102 is assumed to be a laser transmission type sensor, which detects the position of the reference core 101 from the position of the laser beam blocked by the reference core 101. Additionally, as an example of the distance sensor 103, a laser distance sensor is assumed to be installed towards the skirt plates 4 in order to determine the relative distance between a pair of skirt plates 4.

[0062] In Figure 11 , a case where distance sensors 103 are provided on both upper and lower sides is illustrated. This is to confirm the size at the upper and lower positions when adjusting the position of the apron 4.

[0063] Figure 10 is a partial perspective Figure 10 of the device 100 to show a schematic front view of the step bending state. As Figure 11 and Figure 12 indicated, in the positional relationship between each sensor 103 possessed by the device 100 and the object measured with them, the distance from the reference core 101 to the apron 4 is calculated as follows in Equations (1), (2) for the left and right sides, respectively.

[0064] Right apron position: W R = X R + W / 2 - X C · · · (1)

[0065] Left apron position: W L = X L + W / 2 - X C · · · (2)

[0066] Here, W is the relative distance in the pair of distance sensors 103, and is therefore known.

[0067] Figure 11 is a schematic side view of the device 100 partially seen from a viewpoint corresponding to Figure 1 , and a graph showing the bending amount detection value, in the state of Figure 13 . The graph is used to explain the use of data acquired by the reference core sensor 102.

[0068] Figure 1 is a schematic side view of a passenger conveyor that is an applicable object of the device 100 partially seen from a viewpoint corresponding to Figure 14 , and a graph showing the gap detection value. The graph shows the right apron position W R calculated from the reference core sensor 102 and the distance sensor 103.

[0069] The above is the basic structure of the device 100. The acquired measurement data can be recorded in a memory in the control section 104, and then the memory can be read out to confirm the measurement results. At this time, the entire storage medium can be taken out, but it is preferable to be able to confirm the inspection results on the spot in real time. In accordance with this desire, the device 100 (same reference numerals) with good convenience of use and improved practicality is shown in Figure 14 . Figure 10 is a schematic side view of the device 100 (same reference numerals) with good convenience of use and improved practicality. Figure 11 and Figure 14A detailed side view of the device 100 is shown in a partial perspective view.

[0070] Figure 15 The device 100 shown (by the same reference numeral) is a structure in which a wireless communication section 107 and a posture angle sensor 108 are added. The posture angle sensor 108 is capable of detecting a posture angle of the device 100, a traveling vibration of the device 100. The posture angle refers to an angle with respect to the horizontal, and is used to indicate, for example, whether the step 16 is oriented toward the ceiling or is reversed.

[0071] Figure 14 is a functional block diagram of the system structure of the device 100. Figure 16 The data acquired by the reference core sensor 102, the left and right distance sensors 103, and the posture angle sensor 108 are collected in the control section 104, and are wirelessly transmitted to the PC, tablet terminal, or the like 113 outside the passenger conveyor 1 via the wireless communication section 107. In addition, the wireless communication section 117 can be built into the tablet terminal or the like 113.

[0072] Such a device 100 is capable of acquiring the position of the apron 4 in absolute coordinates based on the reference core 101 disposed within the frame 12, and thus more accurately grasps the adjustment amount of the apron 4 on the basis of considering the amount of bending of the step 5, thereby contributing to shortening the position adjustment time of the apron 4.

[0073] In addition, in order to determine the position of an abnormal sound generated due to contact of the device 100 with the apron 4, the device 100 is caused to circulate at a constant speed, and thus the current position (distance of movement) of the device 100 is found from the time from the start position or the reference position of the inspection. Since the acceleration at the time of start is also known and is fixed, this data can be stored in advance in the memory of the control section 104 to be reflected in the operation.

[0074] [Modified Example]

[0075] In the above description, in the basic example of the device 100, the reference core 101 is a wire such as a piano wire, Figure 16 a modified example in which this is replaced by a laser is shown. Figure 8 is a partial perspective view of the device 100 corresponding to Figure 8 is a schematic side view of a passenger conveyor inspection device (main body section is the same as the basic example, and is also referred to as "the device") to which a modified example of the device 100 shown in

[0076] The laser irradiator 109 is disposed at an arbitrary position within the frame 12 (the frame in the vicinity of the drive side end gear 6 or the driven side end gear 7), and the laser irradiation point is aligned with the reference position target 111 to irradiate the laser 110 in a manner parallel to the advancing direction of the step 5 of the passenger conveyor 1.

[0077] Instead of the reference core sensor 102, the light position sensor 112 is installed on the passenger conveyor inspection device 100, and by detecting the position of the laser light 110, the amount of bending of the device 100 can be measured in absolute coordinates. The structure other than the above is the same as that of the device 100 described in the basic example.

[0078] [Supplement]

[0079] The application object of the device 100 is a passenger conveyor 1 such as an escalator 1 and an automatic line (commonly known as a moving sidewalk). In the assembly adjustment of these passenger conveyors 1, the device 100 is an inspection jig for efficiently dynamically checking whether the apron 4 provided on both sides of the step 5 that is circulating is installed at a predetermined position.

[0080] The inspection jig refers to a device mainly used for checking and confirming whether the size, shape, etc. satisfy the accuracy for a product in the middle of assembly or after assembly. When measuring by using a vernier caliper, a micrometer, etc. without using such an inspection jig, the accuracy and speed differ depending on the worker, and in addition, the inspection in the working state of the product is often difficult.

[0081] Therefore, by using such a dedicated inspection jig as the device 100, it is effective to appropriately simulate the actual working state of the product, suppress individual differences, and efficiently perform the determination of whether the product is qualified or not.

[0082] The device 100 has the following structure, action, and effects.

[0083] [1] Figure 1 The device 100 illustrated is an inspection device 100 for a passenger conveyor capable of measuring the assembly mutual positions between components. The device 100 is provided with a reference core 101, a step 5, a reference core sensor 102, a distance sensor 103, and a control section 104. The reference core 101 is a single wire provided in the frame 12 and stretched in parallel with the advancing direction of the passenger conveyor 1.

[0084] The device 100 is an inspection jig (dynamic inspection jig) capable of simulating the actual working state of the passenger conveyor 1 to perform inspection (dynamic inspection). In the device 100, the reference core 101 is provided in the frame 12, and the distance sensor 103 is provided so as to face the reference core 101. Figure 8 、 Figure 12 、 Figure 13 and Figure 15 In the passenger conveyor 1 illustrated in Figs. 1 to 3, as the step chain 13 is driven to circulate, the steps 5 engaged with the step chain 13 also perform a circulating motion. For the assembly finished product of such a passenger conveyor 1, one of the plurality of steps 5 connected to the step chain 13 is replaced with the device 100 as an inspection jig. Thereby, the actual working state of the passenger conveyor 1 is simulated.

[0085] The first function and appearance of such an apparatus 100 is the step 5, and is configured to have the inspection jig as the second function built in the housing of the step 5. That is, the apparatus 100 functions as the inspection jig as the second function, and thus satisfies the appearance and the first function as the step 5 while simulating the actual working state of the passenger conveyor 1.

[0086] As shown in Figure 8 , as the inspection jig, the apparatus 100 is provided with a reference core sensor 102, a distance sensor 103, a control section 104 that performs appropriate arithmetic processing of these detection signals, and a power supply section 105 that drives them. The reference core sensor 102, as shown in Figure 10 , is provided at the front end of a reference core sensor pillar 106 that is vertically provided below the step 5, and is a positional relationship that non-contactingly surrounds the reference core 101.

[0087] As shown in Figure 11 and Figure 13 , the distance sensor 103 is provided at the step 5, and detects the apron distance X from the side surface of the step 5 to the apron 4. The control section 104 comprehensively controls the entire apparatus 100, and using the output signals of the reference core sensor 102 and the distance sensor 103, calculates the position of the apron 4 with respect to the absolute coordinates of the reference core 101.

[0088] According to such an apparatus 100, it is possible to effectively check whether the positions of the aprons 4 provided at both sides of the step 5 that is circulating are appropriate. At this time, the apron distance X detected as the relative position of the bend of the apparatus 100 in the absolute coordinates is subjected to arithmetic processing by the control section 104, and thus a high-precision measurement result is obtained.

[0089] [2] In the above-mentioned [1], it is preferable that the control section 104 stores information that associates the current position of the apparatus 100 and the calculated position of the apron 4 in the dynamic inspection of the passenger conveyor 1, and appropriately outputs the information.

[0090] The current position is calculated based on the position of the reference point in the measurement data stored while the step 5 mounted on the step chain 13 moves as the inspection jig at a prescribed speed, and the elapsed time from the reference time. The position of the apron 4 is also detected by the distance sensor 103 provided at the step 5 as the apron distance X from the side surface of the step 5 to the apron 4. According to such an apparatus 100, Figure 11 , it is possible to effectively check whether the positions of the aprons 4 provided at both sides of the step 5 that is circulating are appropriate, as shown in the graph.

[0091] [3] In the above-mentioned [1], the reference core 101 is preferably formed of a single linear member that is stretched by a tension force within a prescribed range, at a position that does not interfere with the cyclic motion of the step 5. The linear member is preferably, for example, a piano wire or a fishing line. The reference core sensor 102 has a housing space that is U-shaped in cross section orthogonal to the advancing direction of the passenger conveyor 1.

[0092] The reference core 101 needs to be housed and engaged in the space non- contact ly. When the space of the reference core sensor 102 is too large, the precision decreases, and thus is limited to a prescribed size. Therefore, the reference core 101 is not a problem as long as it is less slack and does not interfere with the moving part, but in order not to interfere with the moving part, in order to maintain an appropriate tension force, it is preferable to have a tension force adjustment mechanism via a spring or the like. Thereby, the reference core 101 can be simply and reliably configured.

[0093] [4] In the above-mentioned [1], the control section 104 can include a bending amount determination section not shown. The bending amount determination section determines the bending amount as shown in Equations (1), (2), Figure 12 and Figure 14 First, the skirtboard distance W from the reference core 101 to the skirtboard 4 is calculated using the time-series data of the reference core sensor 102. The change width of the skirtboard distance W is set as the bending amount X0 of the step 5. Then, threshold value determination is performed on whether the bending amount X0 is within the allowable range.

[0094] Based on this, it is possible to realize a dynamic inspection jig for the position of the skirtboard 4 that has not been considered in the past in the passenger conveyor 1. That is, in the relative coordinates that do not take into account the bending amount X0, the position of the skirtboard 4 cannot be correctly known, leaving the possibility of a failure occurring later. In this regard, since the absolute coordinates that take into account the bending amount X0, the device 100 can correctly know the position of the skirtboard 4.

[0095] [5] In the above-mentioned [1], the control section 104 of the device 100 is preferably capable of communicating at least any one of operation information, storage contents, and calculation results with an external electronic terminal 113 in a wireless manner via the wireless communication sections 107, 117. The electronic terminal 113 that becomes the communication object of the control section 104 functions as a remote control console and a result indicator of the device 100 outside the passenger conveyor 1.

[0096] The device 100 is a dynamic inspection jig for the passenger conveyor 1, and if all operations are performed by a person, it will be accompanied by dangerous work. The device 100, which is a dynamic inspection jig that can measure the skirtboard distance X from the side surface of the step 5 to the skirtboard 4 and the distance W from the reference core 101 to the skirtboard 4 during movement, is made safe and correct.

[0097] At this time, the device 100 is mounted on a set of measuring instruments and is performing measurements on a step 5 that is moving at a normal walking speed or in inspection mode at a very low speed. Therefore, from the point of view of preventing danger, even skilled personnel should not approach it. Therefore, the wirelessly connected electronic terminal 113 can be used safely and conveniently outside the passenger conveyor 1 as a remote control console and result indicator for the device 100.

[0098] [6] such as Figure 15 and Figure 16 As shown, the device 100 described above [1] may further include a posture angle sensor 108. This posture angle sensor 108 is preferably capable of detecting at least one of the posture angle of the step 5 forming the inspection fixture and travel vibration. According to the device 100, the conditions required for inspection are detected by the detection output of the posture angle sensor 108 for the posture and travel speed of the step 5, and the control unit 4 identifies this state and appropriately issues a command to perform or stop the inspection. As a result, a good inspection fixture that is easy to use can be provided.

[0099] [7] In the above [1], such as ​ As shown, the reference core 101 is formed by a laser beam with the projection angle and other parameters correctly initially set. This laser beam is received by the reference core sensor 102, and the position of the reference core 101 can be detected by the detection output of the reference core sensor 102.

[0100] In the previous basic example [3], a single linear object formed from piano wire, fishing line, etc., was used as the reference core 101. In this case, it is not easy to maintain a straight shape for a long time in order to prevent the single linear object from slackening and stretching. In contrast, in the present device 100 of [7], the reference core 101 formed by laser light is not an actual object, so it rarely deviates due to aging.
