Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, as an inspection apparatus for a handrail of a passenger conveyor, as disclosed in Japanese Patent Application Laid-Open No. 8-192980, a roller abutting on the surface of a handrail and a vertical displacement of the roller are detected. With a detector,
When the displacement is large, an abnormal condition has been developed.

[0003]

In the above conventional example, while the handrail is being rotated, the vertical displacement of the roller is extracted as an output signal, and the signal is recorded on a recorder. For this reason, when the handrail is rotated continuously for one or more rotations, there is a problem that output signals based on the vertical displacement of the roller at the same location of the handrail are duplicated and recorded on the recorder. Also, if the handrail is stopped before making one rotation, the entire circumference of the handrail surface is not inspected, and an output signal based on the vertical displacement of the roller over the entire circumference of the handrail is not recorded on the recorder. was there.

An object of the present invention is to provide an inspection apparatus for a handrail of a passenger conveyor which can solve the above-mentioned problems with a simple configuration.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a detecting means for detecting an uneven state of a surface of a handrail, data of an uneven state of the handrail surface before use of the handrail detected by the detecting means, and data after the use of the handrail. Storage means for storing handrail surface unevenness state data; determining means for comparing the handrail surface unevenness state data before using the handrail with the handrail surface unevenness state data after using the handrail to determine whether there is an abnormality; And position detecting means for determining the start and end of recording of the handrail surface unevenness state data of the storage means.

According to this configuration, the position detecting means can store the handrail surface unevenness state data of the necessary portion of the handrail in the storage means without duplication.

Further, the position detecting means comprises a sheet-like position mark provided on the outer surface of the ear of the handrail and a sensor for detecting the position mark. When the sensor detects the position mark, the sensor detects the position mark. , A detection signal is sent to the storage means and the storage means is switched between a storage start operation and a storage stop operation.

Thus, it is possible to easily store the output signal based on the vertical displacement of the roller by one rotation of the handrail in the storage means.

Then, as shown in step S5, the handrail upper surface unevenness state data, the handrail side surface unevenness state data, and the like are continuously stored in the storage means 5 as shown in step S5. Simultaneously with the storage, the judgment means 6 compares the handrail surface unevenness state data before the use of the handrail 2 with the handrail surface unevenness state data after the use of the handrail 2 to determine the presence or absence of an abnormality at any time. The result of the determination is displayed on the display means 8 at any time.

(4) Thereafter, in step S6, when the sensor 7B of the position detecting means 7 detects the position mark 7A again, the flow shifts to step S7 to stop the recording of the handrail surface unevenness state data in the storage means 5. .

(5) Thereafter, the operation of the passenger conveyor 1 is stopped, the rotation of the handrail 2 is stopped, and the inspection device 3 for the handrail and the position detecting means 7 including the sensor 7 and the position mark 7A are cleared. The work to check the unevenness of all handrail surfaces is completed.

According to the above operations (1) to (5), (a) When the handrail 2 is rotated and the sensor 7B detects the position mark 7A, the handrail surface unevenness state detected by the detection means 4 is detected. Beginning by storing the data in the storage means 5, the storage is continued until the handrail 2 goes around once and the sensor 7B detects the position mark 7A again, and when the sensor 7B detects the position mark 7A again, the storage means is started. The storage of the handrail surface unevenness state data in No. 5 is stopped. Therefore, only the handrail surface unevenness state data for one round of the handrail 2 can be reliably stored in the storage unit 5, and data in the same location of the handrail 2 is prevented from being redundantly stored in the storage unit 5. it can.

(B) The irregularities on the handrail 2 can be found from the handrail surface unevenness state data. Before the steel cord embedded in the handrail 2 jumps out of the surface of the handrail 2, the handrail 2 Exchange or repair can be performed.

(C) Damage such as cutting of the steel cord in the handrail 2 or abnormal deviation or meandering of the steel cord
Changes in the surface irregularities of the handrail can be grasped in a short time, and the maintenance of the sign of the handrail can be achieved.

[0025]
