Description

Inspection device for passenger conveyor

Technical Field

The present invention relates to an inspection device for a passenger conveyor.

Background

In the operation confirmation inspection of the assembled passenger conveyor, there is an inspection of circulating steps (steps) to confirm the presence or absence of abnormal sounds (abnormal vibrations). As an example of abnormal sounds that occur frequently, there is abnormal sounds that are caused by contact between a circulating step and a skirt guard disposed on both sides thereof.

An operator who assembles the passenger conveyor at the factory estimates the occurrence position by sound and tries to adjust the installation of the skirt guard, but since the inspection environment in the factory is not always in a mute state, it is sometimes difficult to distinguish the surrounding noise and abnormal sound.

In contrast, in order to check whether or not the gap between each of the both side surfaces of the step and the skirt guard is within an allowable range in a short time without depending on the sound, an automatic gap measuring device for a passenger conveyor provided with a distance sensor and a controller is known (for example, patent literature 1). In this automatic clearance measurement device, the controller acquires measurement data obtained by the distance sensor in time series during running of the steps, and determines that a clearance abnormality has occurred when a clearance threshold value is exceeded.

Disclosure of Invention

Technical problem to be solved by the invention

The inspection device for a passenger conveyor described in patent document 1 does not consider step bending occurring in a cycle due to a gap of a step wheel (a gap in an axle direction), a gap between a step and a step chain, an installation error of a rail on which the step wheel travels, and the like.

Such curved steps do not travel all the way on the designed step travel center line. Therefore, in the inspection device for a passenger conveyor of patent document 1, it is possible to detect whether or not the skirt guard is mounted at a predetermined width, but it is difficult to determine whether or not it is mounted at a predetermined position with respect to a reference core (absolute coordinate) of a passenger conveyor frame (hereinafter, simply referred to as "frame").

In this state, that is, in the case where the position of the apron board is adjusted only by the gap information (relative coordinates) between the steps and the apron board irrespective of the bending amount of the steps, the positions of the apron boards 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 steps, an abnormal sound may be generated again after the adjustment, and there is a problem in that it takes time to adjust again.

The present invention has been made in view of the above-described problems, and an object thereof is to provide an inspection device for a passenger conveyor that efficiently inspects whether or not the position of a skirt guard plate disposed on both sides of a step in a noncontact manner is appropriate.

Technical means for solving the technical problems

The present invention for solving the above-mentioned problems is an inspection device for a passenger conveyor capable of measuring an assembly mutual position, comprising: a reference core set in the frame and parallel to the advancing direction of the passenger conveyor; a step as an inspection jig capable of simulating an actual operation state and performing inspection; a reference core sensor disposed on the step; a distance sensor which is disposed on the step and detects a skirt guard plate distance from a side surface of the step to the skirt guard plate; and a control unit that calculates the position of the apron guard relative to the reference core using the output signals of the reference core sensor and the distance sensor.

Effects of the invention

According to the present invention, an inspection device for a passenger conveyor is provided that effectively inspects whether or not the position of a skirt guard plate disposed on both sides of a step in a noncontact manner is appropriate. The problems, structures, and effects other than those described above will become more apparent from the following description of the embodiments.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same components are denoted by the same reference numerals, and when the description is repeated, the description may be omitted. An escalator 1 as a main object of the present invention is illustrated using fig. 1 to 7, and is hereinafter referred to as a passenger conveyor 1 in the above concept.

The present apparatus 100 is an inspection jig for accurately adjusting the position of the apron guard 4 in a short time at the stage of assembling the passenger conveyor 1 in a factory before installation. A basic example of the present apparatus 100 will be described with reference to fig. 8 to 15. A modification of the present apparatus will be described with reference to fig. 16.

The control unit 104 shown in the figures and the bending amount determination unit not shown in the figures are formed by executing a program stored in a memory by a microcomputer or the like. The various components of the present invention need not necessarily exist independently, but may be configured by a plurality of members, a plurality of components may be configured by one member, a certain component may be a part of another component, a part of a certain component may overlap a part of another component, or the like.

(basic constitution of passenger conveyor)

Fig. 1 is a schematic side view partially seen through a general passenger conveyor 1 as a suitable object of the present apparatus 100 (see fig. 8 to 10). The passenger conveyor 1 is transported to a construction site and installed in a factory in a state where it is assembled to complete one block (the balustrade 3 or particularly long and large-sized divided) as shown in fig. 1. The passenger conveyor 1 generally further includes a landing 11, a frame 12, an endless step chain 13, a plurality of steps 5, a skirt guard 4, a balustrade 3, a handrail 2, and a drive device 8.

The boarding and disembarking table 11 is arranged to match the height of each of the upper floor and the lower floor so that passengers can ride on and off. The frame 12 is supported across the boarding and disembarking table 11. The plurality of steps 5 are connected to an endless step chain 13 and move in a cycle. The skirt guards 4 stand on both sides of the movement direction of the steps 5. The balustrade 3 is disposed on the upper portion of the skirt guard 4.

The handrail 2 can be guided to the periphery of the balustrade 3 for circulation. The frame 12 has one end in the longitudinal direction pivotally supporting the driving side end gear 6 and the other end pivotally supporting the driven side end gear 7. The step chain 13 is wound in a recyclable manner across the drive-side end gear 6 and the driven-side end gear 7.

The drive-side end gear 6 is driven by a drive device 8 in its vicinity via a short drive chain 9. The handrail 2 is also driven in synchronism with the steps 5 by the power of the driving means 8.

(basic construction of step)

Next, only one step 5 of the plurality of steps connected is described in close-up with reference to fig. 2, and the other steps are removed from the figure. Fig. 2 is a side sectional view for explaining the posture of the step 5 in the middle portion of the frame 12. The steps 5 are mainly composed of a tread 16, a pad 17, a front wheel 18, a rear wheel 19, a bracket 20, and a step guide 21 on which a passenger sits.

Here, the references to the front wheels 18 and the rear wheels 19 are assumed that the passenger conveyor 1 operates in the ascending direction, respectively. If the direction of movement is reversed, the relationship will also reverse, so the designation will also change. However, since this is not in conformity with the essence of the present invention, this is not considered, and only the case where the front wheels 18 are built in the step chain 13 in the passenger conveyor 1 is exemplified.

As shown in fig. 2, the passenger conveyor 1 has a structure in which a front wheel rail 22 and a rear wheel rail 23 are disposed in a frame 12, and a step 5 moves thereon. In order to suppress the bending of the steps 5, the step guide 21 is disposed so as to protrude from the side surface of the bracket 20 toward the skirt guard 4, and is attached so as to be interposed between the facing surfaces to form spacers (see fig. 3 to 7, 9 to 11, and 14).

(poor mounting of Apron guard)

The mounting failure of the apron protector 4 will be described with reference to fig. 3 to 7, which show extreme states. Fig. 3 is a plan view showing a step generated in the relay portion of the skirt guard 4 as a sample of the gap abnormality to be detected by the present apparatus 100.

In fig. 3, the skirt guard 4c is connected to the skirt guard 4d through a good relay portion that maintains linearity, at least in a plan view. In this case, the gap between the side surface of the bracket 20 and the skirt guard 4 is maintained substantially in an ideal state. In contrast, the skirt guard 4a in fig. 3 cannot maintain linearity with the skirt guard 4 b. Therefore, the gap between the side surface of the bracket 20 and the skirt guard 4a is not ideal.

Fig. 4 is a plan view showing bending of the relay portion of the skirt guard as a sample of the abnormal gap in the mode different from fig. 3. In fig. 4, at least in a plan view, the relay portion between the skirt guard 4a and the skirt guard 4b is curved, and therefore, linearity cannot be maintained.

Therefore, the side surfaces of the bracket 20 and the skirt guard 4a are not parallel to each other, and a gap therebetween is not ideal.

Fig. 5 is a plan view illustrating a skirt guard 4e having a warp with respect to the step advancing direction as a sample of the gap abnormality in the mode different from that of fig. 3 and 4. In fig. 5, the skirt guard 4e having warpage is not parallel to the side surface of the bracket 20 at least in a plan view, and a gap therebetween is not ideal.

Fig. 6 is a plan view illustrating the skirt guard 4a which is not parallel to the step advancing direction even if it is not a relay, as a sample of the gap abnormality different from those of fig. 3 to 5. In fig. 6, at least in a plan view, when the opposing guard plates 4a, 4c are not parallel, the guard plate 4a which is not parallel to the step advancing direction is not parallel to the side surface of the bracket 20, and the gap between them is not ideal.

(state of step bending)

Fig. 7 is a plan view illustrating, as a sample of the gap abnormality different from fig. 3 to 6, the skirt guards 4 on both sides disposed parallel to the step running center line 14 and the steps 5b laterally sliding and bending in the forward right angle direction therebetween.

In fig. 7, a curved state of the steps 5 is shown. The steps 5 are slightly curved in the cycle due to a gap of the wheels of the steps 5 (a gap in the axle direction), a gap of the steps 5 and the step chain 13, an installation error of a rail on which the wheels of the steps 5 travel, and the like. Therefore, the steps 5 do not always stably run on the step running center line 14 in design.

Basic example

Fig. 8 is a schematic side view illustrating the passenger conveyor 1 in a partial perspective view with the present apparatus 100 as an inspection jig mounted. In addition, the portions described in fig. 1 are the same as those indicated by the same reference numerals, and duplicate description is omitted.

Of the plurality of steps 5 disposed in the passenger conveyor 1 of fig. 8, only one step shown in the intermediate position of the frame 12 is replaced with the cost device 100. The reason for showing the present device 100 in the neutral position is simply that it is easily visible in fig. 8 and is located somewhere where it is connected according to the cyclic operation of the other steps 5. Further, the passenger conveyor 1 comprises a reference core 101 parallel to the advancing direction of the steps 5. The reference core 101 is disposed in the frame 12.

In the present device 100, the reference core 101 is a single linear object such as a piano wire or a fishing line, and is not loosely stretched in the frame 12, and is disposed at a position where no disturbance occurs when the present device 100 is circulated. For convenience of explanation, the reference core 101 is shown as being disposed on the same plane as the step running center line in design, but the reference core 101 may be disposed at any position of the frame 12.

Next, the present apparatus 100 will be described in detail with reference to fig. 9 and 10. Fig. 9 is a schematic side view of the present apparatus 100 in the state of fig. 8, which is only partially enlarged in perspective. Fig. 10 is a schematic front view of the present apparatus 100 from the step traveling direction partial perspective view 9. In fig. 9, the front wheel 18, the step chain 13, and the front wheel rail 22 shown in the configuration of the steps 5 in fig. 2 are not shown for simplicity of the drawing, but are actually attached.

The present device 100 includes a reference core sensor 102, a distance sensor 103, a control unit 104, and a power supply unit 105 in addition to the configuration of the steps 5. The reference core sensor 102 is connected to the body of the present device 100 by reference core sensor struts 106.

In the present apparatus 100 as a basic example, as the reference core sensor 102, a laser light transmission type sensor is assumed, and the position of the reference core 101 is detected from the position of the laser light blocked by the reference core 101. Further, as an example of the distance sensor 103, a laser distance sensor is assumed, and the laser distance sensor is attached to the skirt guard 4 in order to measure the relative distance between the pair of skirt guard 4.

Fig. 9 illustrates a case where the distance sensors 103 are disposed at two positions on the upper and lower sides of a single side. This is to confirm the dimensions at the upper and lower positions when adjusting the position of the skirt guard 4.

Fig. 11 is a schematic front view of the present device 100 of the partial perspective view 10 showing a step bending state. As shown in fig. 10 and 11, in the positional relationship between each sensor 103 provided in the present apparatus 100 and the object to be measured using the sensor, the distance from the reference core 101 to the skirt guard 4 is calculated as shown in the following equations (1) and (2), respectively.

Right side apron guard position: w (W) _R ＝X _R +W/2－X _C ····(1)

Left side apron guard position: w (W) _L ＝X _L +W/2－X _C ····(2)

Here, W is the relative distance in the pair of distance sensors 103, and is thus known.

Fig. 12 is a schematic side view of the apparatus 100 in a partial perspective view corresponding to the viewpoint of fig. 1 in the state of fig. 11, and a graph showing a bending amount detection value. The graph is used to illustrate the use of the data acquired by the reference core sensor 102.

Fig. 13 is a schematic side view partially seen through a passenger conveyor as an application object corresponding to the present apparatus 100 of fig. 1, and a graph showing a gap detection value. The graph shows the right side apron guard position W calculated from the reference core sensor 102 and the distance sensor 103 _R 。

The above is the basic structure of the present apparatus 100. The acquired measurement data can be recorded in a memory in the control unit 104, and the memory can be read out to confirm the measurement result. In this case, the entire storage medium may be taken out, but it is preferable to confirm the inspection result in real time on the spot. In accordance with this desire, fig. 14 shows the present device 100 (same reference numerals) which is excellent in use convenience and has improved practicality. Fig. 14 is a detailed side view corresponding to fig. 10 and 11, showing the present device 100 in a partial perspective view only.

The present apparatus 100 shown in fig. 14 (by the same reference numerals) is configured with a wireless communication unit 107 and a posture angle sensor 108 added thereto. The attitude angle sensor 108 can detect an attitude angle of the present apparatus 100 and a traveling vibration of the present apparatus 100. The attitude angle is an angle with respect to the horizontal, and is used to indicate whether the pedal 16 is oriented toward the ceiling or is inverted, for example.

Fig. 15 is a functional block diagram showing the system configuration of the present apparatus 100 of fig. 14. The data acquired by the reference core sensor 102, the left-right distance sensor 103, and the attitude angle sensor 108 are collected in the control unit 104, and are wirelessly transmitted to a PC, a tablet terminal, or the like 113 outside the passenger conveyor 1 via the wireless communication unit 107. The wireless communication unit 117 may be incorporated in the tablet terminal 113 or the like.

Since the present apparatus 100 can acquire the position of the apron guard 4 based on the absolute coordinates of the reference core 101 disposed in the frame 12, the adjustment amount of the apron guard 4 can be grasped more accurately in consideration of the bending amount of the steps 5, and the adjustment time of the position of the apron guard 4 can be shortened.

In order to determine the position where the abnormal sound is generated due to the contact between the device 100 and the apron protector 4, the device 100 is circulated at a constant speed, whereby the current position (movement distance) of the device 100 is obtained from the time from the inspection start position or the reference position. Since the acceleration at the time of start-up is also known and fixed, this data may be stored in advance in the memory of the control section 104 to be reflected in the calculation.

Modification example

In the above description, in the basic example of the present apparatus 100, the reference core 101 is a wire such as a piano wire, and fig. 16 shows a modification in which the wire is replaced with a laser. Fig. 16 is a schematic side view of a passenger conveyor inspection device (the main body is the same as the basic example, also referred to as the "present device") according to a modification of the present device 100 shown in fig. 8.

The laser irradiator 109 is disposed at an arbitrary position (a frame near the driving side end gear 6 or the driven side end gear 7) within the frame 12, and irradiates the laser 110 in alignment with the reference position target 111 so as to be parallel to the advancing direction of the steps 5 of the passenger conveyor 1.

Instead of the reference core sensor 102, the optical position sensor 112 is mounted on the passenger conveyor inspection device 100, and detects the position of the laser light 110, thereby measuring the bending amount of the device 100 in absolute coordinates. The structure other than the above is the same as that of the present apparatus 100 described in the basic example.

[ supplement ]

Suitable objects of the present device 100 are passenger conveyors 1, such as escalators 1 and moving walkways (commonly known as travelators). In the assembly adjustment of the passenger conveyor 1, the present apparatus 100 is a checking jig for effectively and dynamically checking whether the skirt guards 4 disposed on both sides of the steps 5 to be circulated are mounted at predetermined positions.

The inspection jig is a device for inspecting parts, products during assembly or after assembly, and checking whether or not the dimensions, shapes, and the like meet accuracy. When measuring with a vernier caliper, a micrometer, or the like without using such an inspection jig, there are many cases where the accuracy and the speed are different depending on the operator, and inspection in the working state of the product is difficult.

Therefore, it is effective to properly simulate the actual operation state of the product, suppress individual variation, and effectively determine whether the product is acceptable or not, using a dedicated inspection jig such as the present apparatus 100.

The present device 100 has the following structure, operation, and effects.

[1] The present apparatus 100 shown in fig. 8 is an inspection apparatus 100 for a passenger conveyor capable of measuring the assembly mutual position between the respective components. The present device 100 includes a reference core 101, a step 5, a reference core sensor 102, a distance sensor 103, and a control unit 104. The reference core 101 is a single wire rod set in the frame 12 and stretched in parallel with the advancing direction of the passenger conveyor 1.

The present apparatus 100 is an inspection jig (dynamic inspection jig) capable of simulating the actual operation state of the passenger conveyor 1 to inspect (dynamically inspect). In the passenger conveyor 1 shown in fig. 1, 8, 12 and 13, the endless driving of the step chain 13 is accompanied by the endless movement of the plurality of engaged steps 5. For the assembled completed product of such a passenger conveyor 1, one of the plurality of steps 5 connected to the step chain 13 is replaced with the present apparatus 100 as an inspection jig. Thereby simulating the actual operating state of the passenger conveyor 1.

The first function and the appearance of the present device 100 are the steps 5, and an inspection jig as a second function is built in the housing of the steps 5. That is, the present apparatus 100 functions as a second function as an inspection jig, and therefore satisfies the appearance and the first function as the steps 5 while simulating the actual operation state of the passenger conveyor 1.

As shown in fig. 15, the present apparatus 100 includes, as an inspection jig, a reference core sensor 102, a distance sensor 103, a control unit 104 for performing appropriate arithmetic processing on these detection signals, and a power supply unit 105 for driving them. As shown in fig. 8, the reference core sensor 102 is disposed at the front end portion of the reference core sensor column 106 vertically provided below the step 5, and surrounds the reference core 101 in a noncontact manner.

As shown in fig. 10 and 11, the distance sensor 103 is disposed in the step 5, and detects the apron guard distance X from the side surface of the step 5 to the apron guard 4. The control unit 104 comprehensively controls the entire apparatus 100, and calculates the position of the guard panel 4 with respect to the absolute coordinates of the reference core 101 using the output signals of the reference core sensor 102 and the distance sensor 103.

According to the present apparatus 100, it is possible to effectively check whether or not the positions of the skirt guards 4 disposed on both sides of the steps 5 to be circulated are appropriate. At this time, the control unit 104 performs an arithmetic processing for correcting the apron guard distance X detected as the relative position of the curve of the present apparatus 100 on an absolute coordinate, thereby obtaining a measurement result with high accuracy.

[2] In the above [1], the control unit 104 preferably stores information relating the current position of the apparatus 100 to the calculated position of the apron guard 4 in the dynamic inspection of the passenger conveyor 1, and can appropriately output the information.

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 is moved at a prescribed speed as the inspection jig, and the elapsed time from the reference time. The distance sensor 103 provided in the step 5 detects the apron guard distance X from the side surface of the step 5 to the apron guard 4 also for the position of the apron guard 4. According to this apparatus 100, as shown in the graph of fig. 13, it is possible to effectively check whether or not the positions of the skirt guards 4 disposed on both sides of the steps 5 to be circulated are appropriate.

[3] In the above [1], the reference core 101 is preferably formed of a single linear material obtained by stretching a tensile force relaxed within a predetermined range at a position not interfering with the cyclic operation of the steps 5. The string is preferably, for example, a piano string, a fishing line, or the like. The reference core sensor 102 has a receiving space having a U-shaped cross section orthogonal to the advancing direction of the passenger conveyor 1.

The reference core 101 needs to be housed and engaged in the space in a noncontact manner. When the space of the reference core sensor 102 is excessively large, the accuracy is lowered, and thus, the reference core sensor is limited to a predetermined size. Therefore, although the reference core 101 has no problem as long as it has little slack and does not interfere with the operation portion, it is preferable to provide a tension adjustment mechanism via a spring or the like in order to maintain an appropriate tension so as not to interfere with the operation portion. This enables the reference core 101 to be simply and reliably configured.

[4]The method of [1]]The control unit 104 may include a bending amount determination unit, not shown. The bending amount determination unit determines the bending amount as shown in expression (1), expression (2), fig. 11 and fig. 12. First, the apron guard distance W from the reference core 101 to the apron guard 4 is calculated using the time series data of the reference core sensor 102. The width of the change in the apron guard distance W is set to the bending amount X of the step 5 ₀ . Then, for the bending amount X ₀ And judging whether the threshold value is in the allowable range or not.

Based on this, the bending amount X of the steps 5 in the passenger conveyor 1, which has not been conventionally considered, can be realized ₀ Dynamic inspection jigs for the position of the apron guard 4. That is, the bending amount X is not considered ₀ The position of the skirt guard 4 cannot be known correctly, leaving the possibility of a future failure. In this regard, due to the consideration of the bending amount X ₀ The present apparatus 100 can accurately know the position of the skirt guard 4.

[5] In the above [1], the control unit 104 of the present apparatus 100 is preferably capable of wirelessly communicating at least any one of the operation information, the stored content, and the calculation result with the external electronic terminal 113 via the wireless communication units 107, 117. The electronic terminal 113 to be a communication target of the control unit 104 is used as a remote control console and a result indicator of the present apparatus 100 outside the passenger conveyor 1.

The present apparatus 100 is a dynamic inspection jig for the passenger conveyor 1, and if all operations are performed by a person, dangerous operations are accompanied. The present apparatus 100, which is made safe and correct, is a dynamic inspection jig that is capable of measuring the skirt guard distance X from the side of the step 5 to the skirt guard 4 and the distance W from the reference core 101 to the skirt guard 4 during movement.

In this case, since the present apparatus 100 is configured to mount and measure a set of measuring tools on one step 5 moving at a slight speed at a normal speed of walking or as an inspection mode, it is preferable that the apparatus is not closed by even a skilled operator from the viewpoint of preventing danger. Thus, the wirelessly connected electronic terminal 113 can be safely and conveniently used outside the passenger conveyor 1 as a remote console and a result indicator of the present apparatus 100.

[6] As shown in fig. 14 and 15, the present apparatus 100 of [1] above may further include a posture angle sensor 108. The attitude angle sensor 108 is preferably capable of detecting at least one of an attitude angle and a running vibration of the step 5 forming the inspection jig. According to the present apparatus 100, the condition required for the inspection is detected by the detection output of the attitude angle sensor 108 with respect to the attitude and the moving speed of the step 5, and the control unit 4 recognizes the state and appropriately issues an instruction to execute the inspection or stop the inspection. As a result, a good inspection jig that is easy to use can be provided.

[7] In [1], as shown in fig. 16, the reference core 101 is formed of a laser beam having a light projecting angle or the like accurately set initially, and the laser beam is received by the reference core sensor 102, and the position of the reference core 101 may be detected by the detection output of the reference core sensor 102.

In the above-mentioned [3] of the previous basic example, a single line-shaped object formed of a piano wire, a fishing line, or the like is exemplified as the reference core 101. In this case, it is not easy to maintain a straight shape for a long period of time in order to stretch the single string-shaped article without relaxing it. In contrast, in the present apparatus 100 of [7], the reference core 101 formed of the laser beam is not an actual object, and thus, is less likely to be deviated due to aging.
