Embodiment 1.
Fig. 1 is a perspective view of an armrest tensile body inspection device of a passenger conveyor in embodiment 1. Fig. 2 is a longitudinal sectional view of an armrest tensile body inspection device of a passenger conveyor in embodiment 1.
In fig. 1, a moving handrail 1 is provided in a ring shape in a passenger conveyor. For example, the moving handrail 1 is provided to an escalator. For example, the moving handrail 1 is provided to a moving sidewalk. The moving handrail 1 includes a plurality of tensile members 2. The plurality of tensile members 2 are arranged in the movable handrail 1 side by side in the width direction of the movable handrail 1. The plurality of tensile members 2 are each provided in a ring shape like the moving handrail 1.
The handrail tensile body inspection device 3 is used by an operator at the time of maintenance inspection of the passenger conveyor. The handrail tensile body inspection device 3 includes a housing 4, a roller 5, a pair of magnetizers 6, a magnetic sensor 7, a signal processing circuit 8, an inner wiring 9, and an inner connector 10.
The frame 4 forms the outer contour of the handrail tensile body inspection device 3. For example, the outer shape of the housing 4 is formed in a rectangular shape. The width of the rectangular shape is set to be equal to the width of the moving handrail 1.
One of the pair of rollers 5 is provided at a lower portion of one side of the frame 4 in the longitudinal direction of the moving handrail 1. One of the pair of rollers 5 is set to have a width equal to the width of the moving handrail 1. The other of the pair of rollers 5 is provided at a lower portion of the other side of the frame 4 in the longitudinal direction of the moving handrail 1. The other of the pair of rollers 5 is set to have a width equal to the width of the moving handrail 1.
The pair of magnetizers 6 is arranged in parallel on the front surface side of the moving handrail 1 inside the frame 4. One of the pair of magnetizers 6 is adjacent to one of the pair of rollers 5 in the longitudinal direction of the moving handrail 1. One of the pair of magnetizers 6 is set to have a width equal to the width of the moving handrail 1. The other of the pair of magnetizers 6 is adjacent to the other of the pair of rollers 5 in the longitudinal direction of the moving handrail 1. The width of the other of the pair of magnetizers 6 is set to be equal to the width of the moving handrail 1. The pair of magnetizers 6 each have a magnetizer-side magnet 6a.
The magnetic sensor 7 is provided on the front surface side of the moving handrail 1 inside the housing 4. For example, the magnetic sensor 7 is a leakage flux type sensor. The magnetic sensor 7 is disposed between the pair of moving armrests 1. The width of the magnetic sensor 7 is set to be equal to the width of the moving handrail 1. The magnetic sensor 7 includes a detection element 7a and a magnetic sensor-side magnet 7b.
The signal processing circuit 8 is provided inside the housing 4. For example, the signal processing circuit 8 is provided above the magnetic sensor 7. The signal processing circuit 8 is electrically connected to the detection element 7a.
The inner wiring 9 is provided inside the housing 4. One end of the inner wiring 9 is electrically connected to an output portion of the detection element 7a.
The inner connector 10 is provided on the outer surface of the housing 4. The inner connector 10 is electrically connected to the other end of the inner wiring 9.
The external device 11 has a function of storing information. The external device 11 has a function of displaying information.
One end of the outer wiring 12 is electrically connected to an input portion of the external device 11.
The outer connector 13 is electrically connected to the other end portion of the outer wiring 12. The outer connector 13 is mechanically and electrically detachable from the inner connector 10.
As shown in fig. 2, the pair of magnetizer-side magnets 6a are each formed in a C-shape. For example, the pair of magnetizer-side magnets 6a are permanent magnets. In each of the pair of magnetizer-side magnets 6a, the S-pole is disposed on a side close to the magnetic sensor 7. The N pole is arranged on the side remote from the magnetic sensor 7. The end of the S pole and the end of the N pole are disposed so as to face each other along the longitudinal direction of the moving handrail 1.
The detection element 7a is disposed opposite to the moving handrail 1. For example, the detection element 7a is a magnetoresistive element such as AMR, GMR, TMR. For example, the detection element 7a is a magneto-impedance element. The detection element 7a is, for example, a hall element. For example, the detection element 7a is a pickup coil.
The magnetic sensor side magnet 7b is disposed above the detection element 7a. For example, the pair of magnetic sensor side magnets 7b are permanent magnets. In the magnetic sensor side magnet 7b, the end of the S pole is disposed to face upward. The end of the N-pole is disposed to face downward.
Next, an inspection method of the tensile body 2 of the moving handrail 1 will be described with reference to fig. 3 to 7.
Fig. 3 to 7 are longitudinal sectional views of an handrail tensile body inspection device of a passenger conveyor in embodiment 1.
In fig. 3, arrow a indicates the magnetization direction of tensile member 2. Arrow B indicates the direction of the magnetic field generated by the pair of magnetizer-side magnets 6a. Arrow C indicates the direction of the magnetic field generated by the magnetic sensor side magnet 7b. The magnetic field of the magnetic sensor side magnet 7b is adjusted so as not to affect the normal tension body 2.
The tensile body 2 is not magnetized at the left side of the handrail tensile test device 3. Therefore, the magnetization direction is not uniform inside the tensile member 2, including the broken wire rod 2 a.
As shown in fig. 4, when the handrail tensile body inspection device 3 moves to the left, the broken wire 2a is magnetized in the right direction by the magnetic field of one of the pair of magnetizer-side magnets 6a. As a result, the magnetization directions of the broken wires 2a are uniform.
As shown in fig. 5, when the handrail tensile body inspection device 3 is moved further to the left, the magnetization direction of the broken wire rod 2a is maintained in a uniform state.
As shown in fig. 6, when the handrail tensile body inspection device 3 moves further to the left, the broken wire 2a is reversed by the magnetic field of the magnetic sensor side magnet 7b. At this time, the detection element 7a detects the fluctuation of the magnetic field.
As shown in fig. 7, when the handrail tensile body inspection device 3 moves further to the left, the broken wire 2a is reversed again by the magnetic field of the magnetic sensor side magnet 7b. At this time, the detection element 7a detects the fluctuation of the magnetic field.
Although not shown, information of the detection result of the detection element 7a is stored in the external device 11. This information is displayed on the external device 11 as needed.
When the handrail tensile body inspection device 3 moves rightward, the broken wire 2a is magnetized in the leftward direction by the magnetic field of the other of the pair of magnetizer-side magnets 6a. As a result, the magnetization directions of the broken wires 2a are uniform. Then, the detection element 7a detects the fluctuation of the magnetic field similarly to the case where the handrail tensile body inspection device 3 moves rightward.
According to embodiment 1 described above, the magnetic sensor 7 magnetizes the wire 2a magnetized by the magnetizer 6 in the direction opposite to the magnetization direction of the magnetizer 6, and detects the fluctuation of the magnetic field. The variation of the magnetic field at this time is large. Therefore, breakage of the wire 2a in the tensile member 2 can be detected more reliably.
In addition, only one of the pair of magnetizers 6 may be provided. In this case, if the direction and the moving direction of the handrail extension body inspection device 3 are accurately set, the breakage of the wire 2a in the extension body 2 can be detected more reliably.
In contrast, as shown in embodiment 1, if a pair of magnetizers 6 is provided, it is not necessary to pay attention to the direction and the moving direction of the handrail tensile body inspection device 3, and it is possible to more reliably detect the breakage of the wire rod 2a in the tensile body 2.
In addition, the N pole and S pole of all the magnets in the device may be changed.
Next, modification 1 of the magnetic sensor 7 will be described with reference to fig. 8.
Fig. 8 is a longitudinal cross-sectional view of modification 1 of the magnetic sensor used in the handrail tensile body inspection device of the passenger conveyor in embodiment 1.
As shown in fig. 8, the magnetic sensor 7 includes a detection element 7a and a pair of magnetic sensor side magnets 7b.
The detection element 7a is provided to be able to detect a magnetic field.
One of the pair of magnetic sensor side magnets 7b is provided above one side of the detection element 7a. In one of the pair of magnetic sensor side magnets 7b, an end of the S-pole is disposed to face upward. The end of the N-pole is disposed to face downward.
The other of the pair of magnetic sensor side magnets 7b is provided above the other side of the detection element 7a. The other of the pair of magnetic sensor side magnets 7b is provided in parallel with one of the pair of magnetic sensor side magnets 7b in the longitudinal direction of the moving handrail 1. In the other of the pair of magnetic sensor side magnets 7b, the end of the S-pole is disposed to face upward. The end of the N-pole is disposed to face downward.
At this time, the magnetic force is more likely to reach a far place directly below the magnetic sensor 7. Therefore, the broken wire 2a located deep in the moving handrail 1 can also exert a magnetic force. As a result, breakage of the wire 2a in the tensile member 2 can be detected more reliably.
Next, a modification 2 of the magnetic sensor 7 will be described with reference to fig. 9.
Fig. 9 is a longitudinal cross-sectional view of modification 2 of the magnetic sensor used in the handrail tensile body inspection device of the passenger conveyor according to embodiment 1.
As shown in fig. 9, the magnetic sensor 7 includes a detection element 7a and a pair of magnetic sensor side magnets 7b.
The detection element 7a is provided to be able to detect a magnetic field.
One of the pair of magnetic sensor side magnets 7b is provided above the detection element 7a at a position separated from one side of the detection element 7a in the longitudinal direction of the moving handrail 1. In the magnetic sensor side magnet 7b, the end of the N pole is disposed to face upward. The end of the S-pole is disposed to face downward.
The other of the pair of magnetic sensor side magnets 7b is provided above the detection element 7a at a position separated from the other side of the detection element 7a in the longitudinal direction of the moving handrail 1. The other of the pair of magnetic sensor side magnets 7b is provided in parallel with one of the pair of magnetic sensor side magnets 7b in the longitudinal direction of the moving handrail 1. In the magnetic sensor side magnet 7b, the end of the S pole is disposed to face upward. The end of the N-pole is disposed to face downward.
At this time, the magnetic force is more likely to reach a far place directly below the magnetic sensor 7. Therefore, the broken wire 2a located deep in the moving handrail 1 can also exert a magnetic force. As a result, breakage of the wire 2a in the tensile member 2 can be detected more reliably.
Embodiment 2.
Fig. 10 is a longitudinal sectional view of an armrest tensile body inspection device of a passenger conveyor in embodiment 2. The same or corresponding parts as those of embodiment 1 are denoted by the same reference numerals. The description of this portion is omitted.
In embodiment 2, a pair of magnetizer-side magnets 6a are each formed in a U shape. In each of the pair of magnetizer-side magnets 6a, the S-pole is disposed on a side close to the magnetic sensor 7. The N pole is arranged on the side remote from the magnetic sensor 7. The end of the S pole and the end of the N pole are arranged to face the moving handrail 1 side.
According to embodiment 2 described above, in each of the pair of magnetizer-side magnets 6a, the end of the S-pole and the end of the N-pole are arranged toward the moving handrail 1 side. Therefore, each of the pair of magnetizer-side magnets 6a can be easily manufactured.
However, in each of the pair of magnetizer-side magnets 6a, the outside magnetic field toward the outside increases. Therefore, the handrail tensile body inspection device 3 of embodiment 2 can be applied to a case where the coercivity of the tensile body 2 and the wire 2a is greater than that of the outside magnetic field.
Next, a modification of the magnetizer 6 will be described with reference to fig. 11.
Fig. 11 is a longitudinal sectional view of a modification of the magnetizer used in the handrail tensile body inspection device of the passenger conveyor in embodiment 2.
In the magnetizer 6 of fig. 11, the magnetizer-side magnet 6a includes a pair of magnetizer-side magnet portions 14a and a yoke portion 14b.
One of the pair of magnetizer-side magnet portions 14a is formed in a rectangular shape. In one of the pair of magnetizer-side magnet units 14a, an end of the S-pole is disposed to face upward. The end of the N-pole is disposed to face downward.
The other of the pair of magnetizer-side magnet portions 14a is formed in a rectangular shape. In the other of the pair of magnetizer-side magnet portions 14a, the end of the S-pole is disposed downward. The end of the N-pole is disposed to face upward.
The yoke portion 14b is a soft magnetic material. The yoke portion 14b is formed in a rectangular shape. The yoke portion 14b is disposed above the pair of magnetizer-side magnet portions 14 a. One side of the yoke portion 14b is connected to the S pole of one of the pair of magnetizer-side magnet portions 14 a. The other side of the yoke portion 14b is connected to the N pole of the other of the pair of magnetizer-side magnet portions 14 a.
At this time, each of the pair of magnetizer-side magnets 6a is manufactured by a pair of rectangular magnetizer-side magnet portions 14a and a rectangular yoke portion 14b. Therefore, each of the pair of magnetizer-side magnets 6a can be manufactured more easily.
Embodiment 3.
Fig. 12 is a longitudinal cross-sectional view of an armrest tensile body inspection device for a passenger conveyor in embodiment 3. The same or corresponding parts as those of embodiment 1 are denoted by the same reference numerals. The description of this portion is omitted.
In embodiment 3, each of the pair of magnetizer-side magnets 6a is formed in a rectangular shape. In each of the pair of magnetizer-side magnets 6a, an end of the S-pole is disposed to face upward. The end of the N-pole is disposed to face downward.
According to embodiment 3 described above, the pair of magnetizer-side magnets 6a are each formed in a rectangular shape. Therefore, each of the pair of magnetizer-side magnets 6a can be manufactured more easily.
However, the magnetic fields of the pair of magnetizer-side magnets 6a do not form a closed loop. Therefore, the handrail tensile body inspection device 3 of embodiment 3 can be applied to a case where the surroundings of each of the pair of magnetizer-side magnets 6a do not have a magnetic body that interferes.
Next, a modification of the magnetizer 6 will be described with reference to fig. 13.
Fig. 13 is a longitudinal sectional view of a modification of the magnetizer used in the handrail tensile body inspection device of the passenger conveyor in embodiment 3.
As shown in fig. 13, in each of the pair of magnetizers 6, a pair of magnetizer-side magnets 6a are respectively formed in a rectangular shape. In each of the pair of magnetizer-side magnets 6a, an end of the S-pole is arranged to face the magnetic sensor 7 side in the longitudinal direction of the moving handrail 1. The end of the N pole is disposed to face the side opposite to the magnetic sensor 7 side in the longitudinal direction of the moving handrail 1.
In this case, each of the pair of magnetizer-side magnets 6a is also formed in a rectangular shape. Therefore, each of the pair of magnetizer-side magnets 6a can be manufactured more easily.
Embodiment 4.
Fig. 14 is a longitudinal cross-sectional view of an handrail tensile body inspection device of a passenger conveyor in embodiment 4. The same or corresponding parts as those of embodiment 1 are denoted by the same reference numerals. The description of this portion is omitted.
In the handrail tensile body inspection device 3 of embodiment 4, the magnetizer 6 is arranged such that the end of the S pole and the end of the N pole of the magnetizer-side magnet 6a face the moving handrail 1. The magnetic sensor 7 is arranged between the S pole and the N pole of the magnetizer 6.
According to embodiment 4 described above, the number of magnetizers 6 is only one. Therefore, the breakage of the wire 2a in the tensile member 2 can be detected more reliably with a simple structure.
In addition, the magnetic force of magnetizer 6 is applied to tensile member 2 for a longer period of time than in embodiments 1 to 3. Therefore, the magnetization direction can be fixed even for the tensile member 2 having a small coercive force.
In embodiment 1 to embodiment 4, a plurality of detection elements 7a may be provided so as to face the plurality of tensile members 2, respectively. In this case, it is possible to determine which of the plurality of tensile members 2 the wire rod 2a breaks in the tensile member 2.
In embodiments 1 to 4, the handrail tensile test device 3 may be fixed and the movable handrail 1 may be moved. In this case, too, the breakage of the wire 2a in the tensile member 2 can be detected more reliably.
In embodiment 1 to embodiment 4, the bending portion of the moving handrail 1 may be inspected at the upper or lower portion of the passenger conveyor. In this case, inspection can be easily performed while suppressing the shake of the moving handrail 1.
In embodiment 1 to embodiment 4, each of the pair of magnetizers 6 may be composed of a soft magnetic material such as iron, an electromagnetic steel plate, or permalloy, and a magnet.
In embodiment 1 to embodiment 4, each of the pair of magnetizers 6 may be constituted by an electromagnet.
In the pair of magnetizer-side magnet 6a and magnetic sensor-side magnet 7b according to embodiment 1 to embodiment 4, the S-pole and the N-pole may be reversed.
The handrail tensile body inspection device 3 according to embodiment 1 to embodiment 4 may be provided inside the passenger conveyor. In this case, the work of the worker may not be required.
